Detailed Description

(embodiment 1)

An assembly structure of the hood lock device according to embodiment 1 will be described below with reference to fig. 1 to 5. That is, an assembly system including a hood lock device according to embodiment 1 will be described with reference to fig. 1 to 5. In the following description, the vehicle width direction, the vehicle up-down direction, the vehicle front-rear direction, the vehicle right side and the vehicle left side, and the vehicle upper side and the vehicle lower side refer to directions in a state where the hood lock device is mounted on the vehicle.

As shown in fig. 1, a vehicle 10 is equipped with a hood 12 that opens and closes an engine room 11. The hood 12 is swingably supported by an upper edge of a rear portion of the engine room 11 via a hinge (not shown). A hood striker 13 is provided on the inner surface of the hood 12 in a protruding manner. The cover striker 13 includes a hook portion 13A, and the hook portion 13A extends in the vehicle front-rear direction (hereinafter, simply referred to as the front-rear direction) and protrudes downward in a U shape in a state where the cover 12 is closed.

A radiator core support 14 having a substantially rectangular frame shape is provided at the front portion of the vehicle 10. The upper layer 20 constituting the upper portion of the radiator core support 14 is formed of a synthetic resin material, and the portion of the radiator core support 14 other than the upper layer 20 is formed of a metal material.

As shown in fig. 1 and 2, a cover lock device 30 is fixed to the front surface of the upper layer 20. When the cover 12 is closed, the hook portion 13A of the cover striker 13 enters the cover lock device 30, and the cover lock device 30 hooks and locks the hook portion 13A. By locking the hood striker 13 to the hood lock device 30 in this way, the hood 12 is locked in the closed state.

The specific structure of the hood lock device 30 will be described below.

The hood lock 30 is shown in a front view in fig. 2. As shown in fig. 2 and 3, the hood lock device 30 includes a base 31 having a substantially pentagonal shape in front view. The base 31 is formed by bending a metal plate, and has a portion (a notch portion 31A) extending in the vertical direction and notched so as to be open at the upper end of the base 31. The notch 31A has a shape in which the interval between the facing inner surfaces increases toward the vehicle upper side (hereinafter, simply upward). When the cover 12 is closed, the hook portion 13A of the cover striker 13 enters the inside of the cutout portion 31A from the opening at the upper end as shown by the solid arrow in fig. 2.

As shown in fig. 2, the hood lock device 30 has a latch 32. The latch 32 is supported by the base 31 so as to be rotatable about a straight line L1 extending in the front-rear direction, and is constantly urged clockwise in a front view. The latch 32 has a portion (cutout portion 32A) that is cut out so as to be open at the outer edge.

In the state where the cover 12 is opened (opened state), the opening end of the cutout portion 32A of the latch 32 is positioned in the cutout portion 31A of the base 31 in front view. In this opened state, when the hook portion 13A of the hood striker 13 enters the notch portion 31A of the base 31 during the closing operation of the hood 12, the hood lock device 30 enters the notch portion 32A of the latch 32 in the hook portion 13A. When the cover 12 is closed, the hook portion 13A of the cover striker 13 enters the notch portion 32A of the latch 32, and the latch 32 rotates counterclockwise in front view. As a result, the open end of the cutout portion 32A of the latch 32 is positioned outside the cutout portion 31A of the base 31 in the front view (the state shown in fig. 2). Therefore, in the state where the cover 12 is closed (closed state), the hook portion 13A of the cover striker 13 is fitted into a portion surrounded by the inner surface of the notch portion 31A of the base 31 and the inner surface of the notch portion 32A of the latch 32 in front view (state shown in fig. 2). In such a closed state, the rotation of the latch 32 is restricted. Thus, the cover 12 is locked in the closed state.

As shown in fig. 2 and 3, the hood lock device 30 has a catcher 33. The catcher 33 is supported by the base 31 in a rotatable state about a straight line L2 (fig. 2) extending in the front-rear direction, and is constantly urged clockwise in the front view.

The catcher 33 includes an arm portion 34, and the arm portion 34 is disposed on the vehicle right side (hereinafter, only the right side) of the rotation center L2 and extends in the vertical direction. A hook portion 34A that is a portion bent in a hook shape toward the vehicle left side (hereinafter, simply left side) is provided at an upper end of the arm portion 34. The upper end surface 34B of the hook 34A is an inclined surface inclined so as to be positioned on the lower side as facing the projecting end (right end in fig. 2) of the hook 34A.

The catcher 33 includes the lever 35, and the lever 35 is disposed on the left side of the rotation center L2 and extends in the vertical direction. The lever 35 is an operating member that is operated upward when the cover 12 is opened, and when the lever 35 is operated, the catcher 33 rotates counterclockwise in the front view.

When the lever 35 is not operated, the hook 34A of the arm 34 closes the upper opening of the notch 31A of the base 31 in the front view (the state shown in fig. 2). When the cover 12 is closed, the hook 13A of the cover striker 13 abuts on the upper end surface 34B of the hook 34A of the arm 34. At this time, the arm 34 (hook 34A) rotates counterclockwise in front view so as to be pushed and released to the right by the hook 13A of the cover striker 13. Hook portion 13A of cover striker 13 enters notch 31A of base 31.

On the other hand, when the cover 12 is opened, the lever 35 of the catcher 33 is operated upward. As a result, the catcher 33 rotates counterclockwise in the front view, and the hook 34A of the arm 34 moves to a position not overlapping the notch 31A of the base 31 in the front view. As a result, the hook portion 13A of the cover striker 13 can be disengaged from the notch portion 31A of the base 31 without being shielded by the hook portion 34A of the catcher 33, and therefore the cover 12 can be opened.

Hereinafter, a structure for assembling the cover lock device 30 to the upper layer 20 will be described.

The hood lock device 30 has three fixing portions 36, 37, 38 as portions fixed to the upper layer 20. Specifically, a right fixing portion 36 protruding to the right is provided on the right side of the chassis 31, a left fixing portion 37 protruding to the left is provided on the left side of the chassis 31, and a lower fixing portion 38 protruding downward is provided on the lower portion of the chassis 31. Each of these fixing portions 36, 37, and 38 has a substantially flat plate shape extending in the vertical direction and the vehicle width direction, and has an elongated hole-shaped insertion hole 39 extending in the vehicle width direction. The right and left fixing portions 36 and 37 each have a constant width except for the corresponding tip end portion, and extend linearly in the vehicle width direction. In embodiment 1, the right side fixing portion 36 and the left side fixing portion 37 correspond to an engaging portion sandwiched by a pair of engaging pieces.

Three cap nuts 22 having female threads are provided on the upper layer 20. The three cap nuts 22 correspond to the insertion holes 39 of the fixing portions 36, 37, 38 of the cover locking device 30. When the cover lock device 30 is fixed to the upper layer 20, the three bolts 15 (fig. 3) are inserted through the insertion holes 39 of the fixing portions 36, 37, and 38, and are screwed with the three cap nuts 22, respectively. Thereby, the cover lock device 30 is fastened and fixed to the upper layer 20.

As shown in fig. 2 to 4, a pair of right engaging pieces 23 are provided upright at positions corresponding to the right securing portions 36 on the front surface of the upper layer 20 so as to sandwich the right securing portions 36. Further, a pair of left engaging pieces 24 are provided upright at positions corresponding to the left fixing portions 37 on the front surface of the upper layer 20 so as to sandwich the left fixing portions 37. The pair of right engaging pieces 23 are substantially flat plates extending in the front-rear direction and the vehicle width direction, and extend in parallel with each other with a gap therebetween in the up-down direction. The pair of left engaging pieces 24 are substantially flat plates extending in the front-rear direction and the vehicle width direction, and extend in parallel with each other with a gap therebetween in the up-down direction. Of the pair of right engaging pieces 23, the engaging piece 23 on the lower side than the engaging piece 23 on the upper side is thicker. Of the pair of left engaging pieces 24, the engaging piece 24 on the lower side than the engaging piece 24 on the upper side is thicker. The vertical distance between the proximal end portions of the pair of right engaging pieces 23 is substantially the same as the vertical length of the right fixing portion 36. The vertical distance between the base end portions of the pair of left engaging pieces 24 is substantially the same as the vertical length of the left fixing portion 37. A plurality of ribs 25 are integrally formed on the outer side surfaces of the pair of right engaging pieces 23 in the arrangement direction of the pair of right engaging pieces 23. A plurality of ribs 25 are integrally formed on the outer side surfaces of the pair of left engaging pieces 24 in the arrangement direction of the pair of left engaging pieces 24. The plurality of ribs 25 extend in the front-rear direction and the up-down direction, respectively.

The pair of right engaging pieces 23 have facing surfaces, respectively, and these facing surfaces face each other. The pair of left engaging pieces 24 have facing surfaces, respectively, and these facing surfaces face each other. Hook portions 26 as convex portions extending in the vehicle width direction are provided on the opposing surface of the upper right engaging piece 23, the opposing surface of the lower right engaging piece 23, the opposing surface of the upper left engaging piece 24, and the opposing surface of the lower left engaging piece 24, respectively. As shown in fig. 4, the hook portion 26 is provided in the tip end side region of the opposed surface of each of the engaging pieces 23, 24, and a step is provided between the base end side region of the opposed surface of each of the engaging pieces 23, 24 and the corresponding hook portion 26. Further, the projecting end surface 26A of the hook portion 26 is an inclined surface. Specifically, the amount of protrusion of the hook portion 26 decreases from the base end portion toward the tip end portion of the hook portion 26. Therefore, the distance between the two hook portions 26 facing each other increases from the base end portion to the tip end portion of the hook portion 26.

In embodiment 1, the right fixing portion 36, the right engaging piece 23, the left fixing portion 37, and the left engaging piece 24 correspond to a temporarily assembled portion for temporarily assembling the hood lock device 30 to the upper layer 20 by an engaging force.

Hereinafter, a series of operations and effects thereof relating to the assembly of the cover lock device 30 to the upper layer 20 will be described in detail.

When the cover lock device 30 is assembled to the upper layer 20, first, the right engaging piece 23 on the front surface of the upper layer 20 is fitted into the right fixing portion 36 of the cover lock device 30, and the left engaging piece 24 on the front surface of the upper layer 20 is fitted into the left fixing portion 37 of the cover lock device 30. Specifically, as shown in fig. 4, the right fixing portion 36 is pushed between the pair of right engaging pieces 23 and the left fixing portion 37 is pushed between the pair of left engaging pieces 24 while elastically deforming the pair of engaging pieces 23 and 24 so as to be pushed open. At this time, as shown by the hollow arrows in fig. 4, the engaging pieces 23 and 24 on the upper side are elastically deformed so as to be bent upward, and the engaging pieces 23 and 24 on the lower side are elastically deformed so as to be bent downward. When the fixing portions 36 and 37 pass the hook portions 26 of the engaging pieces 23 and 24, the engaging pieces 23 and 24 are restored from elastic deformation, and the hook portions 26 of the engaging pieces 23 and 24 are hooked on the outer edges of the front surfaces of the fixing portions 36 and 37. Thereby, the fixing portions 36 and 37 are sandwiched between the pair of engaging pieces 23 and 24. That is, the right fixing portion 36 is prevented from coming off and falling off from between the pair of right engaging pieces 23, and the left fixing portion 37 is prevented from coming off and falling off from between the pair of left engaging pieces 24.

As described above, according to embodiment 1, the cover lock device 30 can be temporarily assembled to the upper layer 20 by a simple operation of fitting the right fixing portion 36 between the pair of right engaging pieces 23 and fitting the left fixing portion 37 between the pair of left engaging pieces 24.

In embodiment 1, the engaging piece 23 on the lower side of the pair of right engaging pieces 23 than the upper engaging piece 23 is thicker. Of the pair of left engaging pieces 24, the engaging piece 24 on the lower side than the engaging piece 24 on the upper side is thicker. Accordingly, the engaging pieces 23 and 24 on the upper side can be thinned and easily deformed, and therefore, the work of fitting the right fixing portion 36 between the pair of right engaging pieces 23 and the work of fitting the left fixing portion 37 between the pair of left engaging pieces 24 can be smoothly performed. Further, since the lower engaging pieces 23 and 24 can be thickened and relatively hardly deformed, the fixing portions 36 and 37 can be appropriately supported by the lower engaging pieces 23 and 24.

In embodiment 1, a pair of right engaging piece 23 and right fixing portion 36 are provided at the right side portion of hood lock device 30, and a pair of left engaging piece 24 and left fixing portion 37 are provided at the left side portion of hood lock device 30. Therefore, when the hood lock device 30 is temporarily assembled to the upper layer 20, both side portions of the hood lock device 30 are supported by the upper layer 20. Therefore, the cover lock device 30 can be supported in a stable state by the upper layer 20.

In addition, the following is assumed: in the state where the cover lock device 30 is temporarily assembled to the upper deck 20 in this way, the upper deck 20 is transported to an assembly factory where the vehicle 10 is assembled, or the upper deck 20 is transported to a workshop in a next process in the assembly factory. According to embodiment 1, the cover lock device 30 is attached to the upper layer 20 by engagement of the fixing portions 36 and 37 of the cover lock device 30 with the corresponding pair of engagement pieces 23 and 24 of the upper layer 20. Therefore, when the upper layer 20 is transported in a state where the cover lock device 30 is temporarily assembled, the cover lock device 30 can be prevented from being detached from the upper layer 20.

In embodiment 1, the vertical interval in the proximal end region of the pair of right engaging pieces 23 is substantially equal to the vertical length of the right fixing portion 36, and the vertical interval in the proximal end region of the pair of left engaging pieces 24 is substantially equal to the vertical length of the left fixing portion 37. Therefore, when the hood lock device 30 is temporarily assembled to the upper deck 20, the hood lock device 30 can slide in the vehicle width direction with respect to the upper deck 20.

In embodiment 1, the shapes of the engaging pieces 23, 24 and the fixing portions 36, 37 are determined so as to satisfy the requirements of suppressing the right fixing portion 36 from falling out from between the pair of right engaging pieces 23, suppressing the left fixing portion 37 from falling out from between the pair of left engaging pieces 24, and allowing the relative movement of the fixing portions 36, 37 with respect to the engaging pieces 23, 24.

Next, the assembly position of the hood lock device 30 is adjusted as the position of the hood lock device 30 assembled to the upper layer 20. Specifically, the hood 12 is closed in a state where the hood lock device 30 is temporarily assembled to the upper layer 20 fixed to the vehicle 10.

In this case, first, the hook 13A of the cover striker 13 abuts against the upper end surface 34B of the hook 34A of the catcher 33. The upper end surface 34B of the hook 34A is an inclined surface extending downward as it faces the projecting end. Therefore, when the hook portion 13A of the cover striker 13 abuts against the upper end surface 34B, the catcher 33 is rotated counterclockwise in the front view by the pressing of the hook portion 13A of the cover striker 13. Thereby, the hook portion 13A of the cover striker 13 enters the inside of the notch portion 31A of the recessed base 31 so as to push open the hook portion 34A of the catcher 33.

Fig. 5 shows a positional relationship between the base 31 of the hood lock device 30 and the hook portion 13A of the hood striker 13 in a case where the temporary assembly position of the hood lock device 30 is shifted to the left (right in fig. 5). As shown in fig. 5, in this case, the hook portion 13A of the cover striker 13 abuts on the right side (left side in fig. 5) surface of the inner surface of the notch portion 31A of the base 31. Here, as described above, the hood lock device 30 can move in the vehicle width direction with respect to the upper deck 20 even in a state of being temporarily assembled to the upper deck 20. Therefore, when the hook portion 13A of the hood striker 13 abuts against the inner surface (specifically, the right-side surface) of the cutout portion 31A and presses the inner surface of the cutout portion 31A, the hood lock device 30 moves to the right relative to the upper layer 20 as indicated by the solid arrow in fig. 5. On the other hand, when the temporary assembly position of the hood lock device 30 is shifted to the right, the hook portion 13A of the hood striker 13 abuts against and presses the left inner surface of the inner surfaces of the notch portions 31A, and the hood lock device 30 moves to the left with respect to the upper layer 20. On the other hand, in the case where the temporary assembly position of the hood lock device 30 is within the allowable range, the hood lock device 30 does not move relatively with respect to the upper layer 20 when the hood 12 is closed.

By closing the cover 12 in the state where the cover lock device 30 is temporarily assembled to the upper layer 20 in this way, the position of the cover lock device 30 in the vehicle width direction is a position that does not prevent the hook portion 13A of the cover striker 13 from smoothly entering the notch portion 31A of the base 31.

Then, the hood lock 30 is fixed to the upper layer 20. Specifically, the three fixing bolts 15 (fig. 3) are inserted through the insertion holes 39 of the fixing portions 36, 37, and 38 of the cover lock device 30, and are screwed with the cap nuts 22 of the upper layer 20. Thereby, the cover lock device 30 is fastened and fixed to the upper layer 20. In embodiment 1, the cover locking device 30 can be fastened and fixed by the bolt 15 in the state in which the cover 12 is locked in the closed state.

According to embodiment 1, the cover lock device 30 can be temporarily assembled to the upper layer 20 by the work of fitting the right fixing portion 36 between the pair of right engaging pieces 23 of the upper layer 20 and fitting the left fixing portion 37 between the pair of left engaging pieces 24 of the upper layer 20. This allows the hood lock device 30 to be supported by the upper layer 20 before the hood lock device 30 is fixed to the upper layer 20. In this temporarily assembled state, the position of the hood lock device 30 in the vehicle width direction can be adjusted by the operation of moving the hood lock device 30 relative to the upper deck 20. As described above, according to embodiment 1, the work of temporarily assembling the hood lock device 30 and the work of adjusting the position can be easily performed, and therefore the work of assembling the hood lock device 30 can be easily performed.

In embodiment 1, the upper layer 20 of the radiator core support 14 is formed by a synthetic resin material. In general, the upper layer 20 made of synthetic resin is more likely to have larger manufacturing errors than the upper layer made of metal. Therefore, in the assembly structure of embodiment 1 in which the cover lock device 30 is fixed to the upper layer 20 made of synthetic resin, there is a possibility that the relative positions of the cover lock device 30 and the cover striker 13 are deviated. According to embodiment 1, in the assembly structure in which the hood lock device 30 is fixed to the synthetic resin upper layer 20, the position of the hood lock device 30 in the vehicle width direction can be adjusted, and the assembly work of the hood lock device 30 is facilitated.

As described above, according to embodiment 1, the following effects are obtained.

(1) The work of temporarily assembling the cover lock device 30 to the upper layer 20 and the work of adjusting the position of the cover lock device 30 can be easily performed, and therefore the work of assembling the cover lock device 30 is easy.

(2) When the hood lock device 30 is temporarily assembled to the upper layer 20, both side portions of the hood lock device 30 are supported by the upper layer 20, and therefore the hood lock device 30 can be supported in a stable state by the upper layer 20.

(3) By a simple operation of fitting the right fixing portion 36 between the pair of right engaging pieces 23 and fitting the left fixing portion 37 between the pair of left engaging pieces 24, the cover lock device 30 can be temporarily assembled to the upper layer 20 so that the upper layer 20 and the cover lock device 30 can move relatively in the vehicle width direction.

(4) In the assembly structure in which the hood lock device 30 is fixed to the synthetic resin upper layer 20, the position of the hood lock device 30 in the vehicle width direction can be adjusted, and the assembly work of the hood lock device 30 can be easily performed.

(embodiment 2)

Hereinafter, an assembly structure of the hood lock device according to embodiment 2 will be described with reference to fig. 6 and 7, focusing on differences from embodiment 1. In the following, the same components as those in embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In embodiment 2 and embodiment 1, only the engaging piece of the upper layer is different in shape.

The shape of the engaging piece of embodiment 2 will be explained below.

As shown in fig. 6 and 7, a pair of right engaging pieces 41 are provided upright at positions corresponding to the right securing portions 36 on the front surface of the upper layer 40 so as to sandwich the right securing portions 36. Further, a pair of left engaging pieces 45 are provided upright at positions corresponding to the left fixing portions 37 on the front surface of the upper layer 40 so as to sandwich the left fixing portions 37.

The pair of right engaging pieces 41 are plate-shaped extending in the front-rear direction and the vehicle width direction, and extend in parallel with each other with a gap therebetween in the up-down direction. The pair of left engaging pieces 45 are plate-shaped extending in the front-rear direction and the vehicle width direction, and extend in parallel with each other with a gap therebetween in the up-down direction. The pair of right engaging pieces 41 and the pair of left engaging pieces 45 each extend in an S-shaped cross section when viewed in the vehicle width direction. That is, the interval in the base end side region (the left region in fig. 7) of the pair of right engaging pieces 41 is wider than the interval in the tip end side region (the right region in fig. 7) of the pair of right engaging pieces 41. Similarly, the distance between the proximal end regions of the pair of left engaging pieces 45 is wider than the distance between the distal end regions of the pair of left engaging pieces 45.

The distance between the distal ends of the pair of right engaging pieces 41 is substantially equal to the vertical length of the right fixing portion 36, and the distance between the distal ends of the pair of left engaging pieces 45 is substantially equal to the vertical length of the left fixing portion 37. Of the pair of right engaging pieces 41, the engaging piece 41 on the lower side than the engaging piece 41 on the upper side is thickened. Of the pair of left engaging pieces 45, the engaging piece 45 on the lower side than the engaging piece 45 on the upper side is thickened. Further, a plurality of ribs 46 are integrally formed on the outer side surfaces of the pair of right engaging pieces 41 in the arrangement direction of the pair of right engaging pieces 41. A plurality of ribs 46 are integrally formed on the outer side surfaces of the pair of left engaging pieces 45 in the arrangement direction of the pair of left engaging pieces 45. The plurality of ribs 46 extend in the front-rear direction and the up-down direction, respectively.

Further, convex portions (hooking portions 47) extending in the vehicle width direction are provided on the facing surfaces of the pair of right engaging pieces 41 and the facing surfaces of the pair of left engaging pieces 45, respectively. As shown in fig. 7, the hook portion 47 is provided in the distal end side region of the facing surface of each of the engaging pieces 41, 45, and a step is provided between the proximal end side region of the facing surface of each of the engaging pieces 41, 45 and the corresponding hook portion 47. The projecting end surface 47A of each hook 47 is an inclined surface in which the projecting amount of the hook 47 is inclined so as to decrease toward the tip.

In embodiment 2, the right fixing portion 36, the right engaging piece 41, the left fixing portion 37, and the left engaging piece 45 correspond to a temporarily assembled portion for temporarily assembling the hood lock device 30 to the upper layer 40 by an engaging force.

According to embodiment 2 described above, the operational effects described in the following (5) are obtained in addition to the effects similar to the effects described in the above (1) to (4).

(5) In embodiment 2, the pair of right engaging pieces 41 and the pair of left engaging pieces 45 have an S-shaped cross section when viewed in the vehicle width direction. Therefore, compared to the case where the engaging pieces are flat, the flexing portions of the engaging pieces 41, 45 can be made longer, and the engaging pieces 41, 45 can be made to flex easily. Therefore, when the cover lock device 30 is temporarily assembled to the upper layer 40, the work of fitting the right fixing portion 36 between the pair of right engaging pieces 41 and fitting the left fixing portion 37 between the pair of left engaging pieces 45 can be smoothly performed so as to push the pair of engaging pieces 41 and 45 apart.

(embodiment 3)

Hereinafter, an assembly structure of the hood lock device according to embodiment 3 will be described with reference to fig. 8 and 9, focusing on differences from embodiment 1. In the following, the same components as those in embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In embodiment 3 and embodiment 1, the right and left fixing portions of the hood lock device are different in shape.

The shapes of the right and left fixing portions of embodiment 3 will be described below.

As shown in fig. 8 and 9, a right fixing portion 51 protruding to the right is provided on the right side of the base 31 of the hood lock device 50, and a left fixing portion 52 protruding to the left is provided on the left side of the base 31. The right and left fixing portions 51 and 52 are plate-shaped extending in the vehicle width direction. More specifically, the right-side fixing portion 51 and the left-side fixing portion 52 are formed integrally with a base wall 53, an upper wall 54, and a lower wall 55, the base wall 53 extending in a flat plate shape in the vertical direction, the upper wall 54 standing forward from the upper end of the base wall 53, and the lower wall 55 standing forward from the lower end of the base wall 53. In each of the right and left fixing portions 51 and 52, a boundary portion between the corresponding base wall 53 and the corresponding upper wall 54 and a boundary portion between the corresponding base wall 53 and the corresponding lower wall 55 are curved. That is, each of the fixing portions 51 and 52 has an end surface (left end surface in fig. 9) close to the upper layer 20, and an upper portion and a lower portion of the end surfaces of each of the fixing portions 51 and 52 are surfaces curved so as to be separated from the upper layer 20. The end surfaces of the fixing portions 51 and 52 face the upper layer 20 when the cover lock device 50 is temporarily assembled to the upper layer 20.

In embodiment 3, the right fixing portion 51, the right engaging piece 23, the left fixing portion 52, and the left engaging piece 24 correspond to a temporarily assembled portion for temporarily assembling the hood lock device 50 to the upper layer 20 by an engaging force.

According to embodiment 3 described above, the following operational effect (6) is obtained in addition to the same effects as those described in (1) to (4) above.

(6) When the cover lock device 50 is temporarily assembled, the right fixing portion 51 is pushed between the pair of right engaging pieces 23 and the left fixing portion 52 is pushed between the pair of left engaging pieces 24 while being elastically deformed so as to push the pair of engaging pieces 23 and 24 apart. At this time, as shown by the hollow arrows in fig. 9, the engaging pieces 23 and 24 on the upper side are elastically deformed so as to be bent upward, and the engaging pieces 23 and 24 on the lower side are elastically deformed so as to be bent downward. In embodiment 3, the upper and lower portions of the end surfaces of each of the fixing portions 51 and 52 close to the upper layer 20 are curved so as to be away from the upper layer 20. Therefore, at this time, the curved surfaces of the upper and lower ends of the fixing portions 51, 52 abut against the inner surfaces of the pair of engaging pieces 23, 24 (specifically, the protruding end surfaces 26A of the hook portion 26). Thus, the upper and lower ends of the fixing portions 51, 52 are less likely to be caught by the inner surfaces of the engaging pieces 23, 24, and therefore, the work of fitting the right fixing portion 51 between the pair of right engaging pieces 23 and fitting the left fixing portion 52 between the pair of left engaging pieces 24 can be smoothly performed.

(embodiment 4)

Hereinafter, an assembly structure of the hood lock device according to embodiment 4 will be described with reference to fig. 10 to 13, focusing on differences from embodiment 1. In the following, the same components as those in embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In embodiment 4 and embodiment 1, the shapes of the right and left fixing portions of the cover lock device are different from the shape of the engaging piece on the upper layer.

The shapes of the fixing portion and the engaging piece of embodiment 4 will be described below.

First, the right and left fixing portions of embodiment 4 will be described.

As shown in fig. 10 to 13, a right fixing portion 61 protruding to the right is provided on the right side of the base 31 of the hood lock device 60, and a left fixing portion 62 protruding to the left is provided on the left side of the base 31. The right and left fixing portions 61 and 62 are plate-shaped extending in the vehicle width direction. Specifically, the right-side fixing portion 61 and the left-side fixing portion 62 include a flat plate-shaped base wall 63 extending in the vertical direction, an upper arm 64 standing rearward from an upper end of the base wall 63, and a lower arm 65 standing rearward from a lower end of the base wall 63. The upper arm 64 and the lower arm 65 are plate-shaped and extend in parallel extending in the vehicle width direction and the front-rear direction. The upper arm 64 and the lower arm 65 are each provided with an elongated hole (engagement hole 66) extending in the vehicle width direction.

Next, the right and left engaging pieces 71 and 72 of the upper layer 70 and the peripheral structure thereof according to embodiment 4 will be described.

Through holes (slits 73) extending in the vehicle width direction are formed in the upper layer 70 at positions corresponding to the respective arms 64, 65 of the right-side fixing portion 61. In addition, through-holes (slits 73) extending in the vehicle width direction are formed in the upper layer 70 at positions corresponding to the respective arms 64, 65 of the left-side fixing portion 62. The width of each slit 73 is slightly larger than the thickness of the corresponding arm 64, 65, and the length of each slit 73 is longer than the length of the corresponding arm 64, 65 in the vehicle width direction. When the cover lock device 60 is assembled to the upper layer 70, the corresponding arms 64 and 65 are inserted into the respective slits 73.

A pair of right engaging pieces 71 are provided upright on the rear surface of the upper layer 70 at positions corresponding to the right fixing portions 61. The upper surface of the upper arm 64 and the lower surface of the lower arm 65 of the right fixing portion 61 are sandwiched between the pair of right engaging pieces 71. A pair of left engaging pieces 72 are provided upright on the rear surface of the upper layer 70 at positions corresponding to the left fixing portions 62. The upper surface of the upper arm 64 and the lower surface of the lower arm 65 of the left fixing portion 62 are sandwiched between the pair of left engaging pieces 72.

The pair of right engaging pieces 71 extend in parallel in a substantially flat plate shape extending in the front-rear direction and the vehicle width direction. The pair of left engaging pieces 72 extend in parallel in a substantially flat plate shape extending in the front-rear direction and the vehicle width direction. The interval between the facing surfaces of the pair of right engaging pieces 71 is substantially the same as the interval between the upper surface of the upper arm 64 and the lower surface of the lower arm 65 of the right fixing portion 61. The distance between the facing surfaces of the pair of left engaging pieces 72 is substantially the same as the distance between the upper surface of the upper arm 64 and the lower surface of the lower arm 65 of the left fixing portion 62. The pair of right engaging pieces 71 each have a spring portion 75, and the spring portions 75 are surrounded by through holes 74 (fig. 11) extending in a U shape from three directions (rear side, right side, left side). The pair of left engaging pieces 72 each have a spring portion 75 and are surrounded by a through hole 74 extending in a U shape from three directions (rear side, right side, left side). The spring portion 75 is elastically deformable so as to rock in the vertical direction with respect to the peripheral edge portion surrounding the spring portion 75. Engaging protrusions 76 (see fig. 11) protruding in a substantially hemispherical shape are provided at positions of the respective spring portions 75 that face the engaging holes 66.

In embodiment 4, the right fixing portion 61, the right engaging piece 71, the left fixing portion 62, and the left engaging piece 72 correspond to a temporarily assembled portion in which the hood lock device 60 is temporarily assembled to the upper layer 70 by an engaging force.

Hereinafter, the operation of temporarily assembling the cover lock device 60 to the upper layer 70 and the operational effects thereof will be described in detail.

As shown in fig. 13, when the cover lock device 60 is temporarily assembled to the upper layer 70, the upper arm 64 and the lower arm 65 of the right-side fixing portion 61 are inserted into the slit 73 of the upper layer 70, and the upper arm 64 and the lower arm 65 of the left-side fixing portion 62 are inserted into the slit 73 of the upper layer 70. As a result, as shown by the hollow arrows in fig. 13, the right fixing portion 61 is pushed between the pair of right engaging pieces 71 and the left fixing portion 62 is pushed between the pair of left engaging pieces 72 while being elastically deformed so as to push the pair of engaging pieces 71 and 72 (specifically, the spring portions 75 thereof) open. At this time, the spring portions 75 of the upper engaging pieces 71, 72 are elastically deformed so as to bend upward, and the spring portions 75 of the lower engaging pieces 71, 72 are elastically deformed so as to bend downward. When the engaging hole 66 of each arm 64, 65 is located at a position corresponding to the engaging projection 76 of the corresponding spring portion 75, the spring portion 75 is restored from elastic deformation. Accordingly, the engagement projection 76 of each spring portion 75 is fitted into the engagement hole 66 of the corresponding arm 64, 65 (the state shown in fig. 13).

Thus, the fixing portions 61 and 62 (specifically, the arms 64 and 65) are sandwiched by the pair of engaging pieces 71 and 72, and the engaging projections 76 of the corresponding spring portions 75 are fitted into the engaging holes 66 of the arms 64 and 65. Therefore, the right fixing portion 61 and the left fixing portion 62 can be prevented from falling off between the pair of right engaging pieces 71 and the pair of left engaging pieces 72, respectively.

As described above, according to embodiment 4, the cover lock device 60 can be temporarily assembled to the upper layer 70 by a simple operation of fitting the right fixing portion 61 between the pair of right engaging pieces 71 and fitting the left fixing portion 62 between the pair of left engaging pieces 72.

As shown in fig. 10 and 12, in embodiment 4, the length of each slit 73 is longer than the length of the corresponding arm 64, 65 in the vehicle width direction. Therefore, the arms 64 and 65 can move relatively in the vehicle width direction inside the corresponding slits 73. The engagement hole 66 of each arm portion 34 is formed in an elongated hole shape extending in the vehicle width direction. Therefore, the engaging projection 76 of each spring portion 75 can move relatively in the vehicle width direction in the engaging hole 66 of the corresponding arm 64, 65. Therefore, at this time, although the hood lock device 60 is temporarily assembled to the upper layer 70, the hood lock device 60 is slidable in the vehicle width direction with respect to the upper layer 70.

In embodiment 4, the shapes of the engaging pieces 71, 72, the slit 73, and the fixing portions 61, 62 are determined so as to satisfy the requirements of suppressing the right fixing portion 61 from falling out from between the pair of right engaging pieces 71, suppressing the left fixing portion 62 from falling out from between the pair of left engaging pieces 72, and allowing the relative movement of the fixing portions 61, 62 with respect to the engaging pieces 71, 72.

In embodiment 4, the fixing portions 61 and 62 include an upper arm 64 extending in the front-rear direction on the upper side, a lower arm 65 extending in the front-rear direction on the lower side, and a base wall 63 extending in the vertical direction so as to connect the upper arm 64 and the lower arm 65. The pair of right engaging pieces 71 extend in parallel in a substantially flat plate shape extending in the front-rear direction and the vehicle width direction, and are erected so as to sandwich the upper surface of the upper arm 64 and the lower surface of the lower arm 65 of the right fixing portion 61 between the pair of right engaging pieces 71. The pair of left engaging pieces 72 extend in parallel in a substantially flat plate shape extending in the front-rear direction and the vehicle width direction, and are erected so that the upper surface of the upper arm 64 and the lower surface of the lower arm 65 of the left fixing portion 62 are sandwiched between the pair of left engaging pieces 72. Therefore, as shown in fig. 13, the outer surfaces of the fixing portions 61 and 62 (specifically, the upper surface of the upper arm 64 and the lower surface of the lower arm 65) can be configured to come into surface contact with the inner surfaces of the pair of engaging pieces 71 and 72. Thus, the fixing portions 61 and 62 can be supported in a stable state by the pair of engaging pieces 71 and 72.

According to embodiment 4 described above, the following effect (7) is obtained in addition to the same effects as those described in (1) to (4) above.

(7) Since the outer surfaces of the fixing portions 61 and 62 and the inner surfaces of the pair of engaging pieces 71 and 72 can be configured to come into surface contact with each other, the fixing portions 61 and 62 can be supported in a stable state by the pair of engaging pieces 71 and 72.

(embodiment 5)

Hereinafter, an assembly structure of the hood lock device according to embodiment 5 will be described with reference to fig. 14 to 16, focusing on differences from embodiment 1. In the following, the same components as those in embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In embodiment 5 and embodiment 1, the right and left securing portions of the cover lock device are different in shape from the upper layer.

The shapes of the right and left securing portions and the shape of the upper layer in embodiment 5 will be described below.

First, the shapes of the right and left fixing portions of embodiment 5 will be described.

As shown in fig. 14 to 16, a right fixing portion 81 protruding to the right is provided on the right side of the base 31 of the hood lock device 80, and a left fixing portion 82 protruding to the left is provided on the left side of the base 31.

Each of the right-side fixing portion 81 and the left-side fixing portion 82 has a flat plate-like base wall 83 extending in the vehicle width direction and the vertical direction, and one lower arm 84 and two upper arms 85 provided to protrude from an upper end of the base wall 83. The lower arm 84 is provided to project rearward from an upper end of the base wall 83, and has a plate shape extending in the vehicle width direction and the front-rear direction. The projecting end portion of the lower arm 84 is bent downward. In addition, the lower arm 84 is provided with a square through hole (engagement hole 84A). The upper arms 85 are provided at the upper ends of the base walls 83 so as to sandwich the lower arms 84 between the upper arms 85. These upper arms 85 are L-shaped plate-like. More specifically, the base end portion of the upper arm 85 is plate-shaped extending in the vehicle width direction and the vertical direction, and the tip end portion of the upper arm 85 is plate-shaped protruding rearward from the upper end of the base end portion and extending in the vehicle width direction and the front-rear direction. The top end portion of the upper arm 85 extends above the lower arm 84. The protruding end portion of the upper arm 85 is bent upward.

Next, the shape of the upper layer 90 of embodiment 5 will be described.

The upper deck 90 includes a plate-shaped standing wall portion 91 extending in the vertical direction and the vehicle width direction, and a plate-shaped upper wall portion 92 extending in the front-rear direction and the vehicle width direction and projecting rearward from an upper end of the standing wall portion 91. A rectangular engaging projection 92A is provided on the lower surface of the upper wall 92 so as to protrude at a position facing the engaging hole 84A of the lower arm 84. The length of the engagement projection 92A in the vehicle width direction is shorter than the length of the engagement hole 84A of the lower arm 84 in the vehicle width direction.

A through hole (slit 93) extending in the vehicle width direction is provided in the upright wall portion 91 of the upper layer 90 at a position corresponding to the lower arm 84 of the right-side fixing portion 81. In addition, a through-hole (slit 93) extending in the vehicle width direction is also provided in the upright wall portion 91 of the upper layer 90 at a position corresponding to the lower arm 84 of the left-side fixing portion 82. These slits 93 extend along the surface of the standing wall portion 91. The width of the slit 93 is larger than the thickness of the lower arm 84, and the length of the slit 93 is longer than the length of the lower arm 84 in the vehicle width direction. When the cover lock device 80 is assembled to the upper layer 90, the lower arms 84 of the fixing portions 81 and 82 are inserted into the slits 93, respectively. In embodiment 5, the upper arm 85 and the lower arm 84 correspond to a pair of engaging pieces, the upper wall 92 corresponds to an engaging portion, and the right side fixing portion 81, the left side fixing portion 82, and the upper wall 92 correspond to a temporarily-assembled portion for temporarily assembling the hood lock device 80 to the upper layer 90 by an engaging force.

Hereinafter, the operation of temporarily assembling the cover lock device 80 to the upper layer 90 and the operational effects thereof will be described together.

As shown in fig. 16, when the cover lock device 80 is temporarily assembled to the upper layer 90, the lower arms 84 of the fixing portions 81 and 82 are inserted into the slits 93 so that the upper arms 85 of the fixing portions 81 and 82 move along the upper surface of the upper wall portion 92. As a result, as shown by the hollow arrows in fig. 16, the upper wall portion 92 is pushed between the two upper arms 85 and the one lower arm 84 while being elastically deformed so as to push the upper arm 85 and the lower arm 84 apart from each other. At this time, the upper arm 85 is elastically deformed so as to bend upward, and the lower arm 84 is elastically deformed so as to bend downward. When the engaging hole 84A of the lower arm 84 is positioned to face the engaging projection 76 on the lower surface of the upper wall 92, the engaging projection 92A of the upper wall 92 is fitted into the engaging hole 66 of the lower arm 84 (the state shown in fig. 16). Thus, the upper wall portion 92 is sandwiched between the one lower arm 84 and the two upper arms 85, and the engagement projection 76 of the upper wall portion 92 is fitted into the engagement hole 84A of the lower arm 84. Therefore, the fixing portions 81 and 82 are prevented from coming off the upper layer 90 (specifically, the upper wall portion 92).

As described above, according to embodiment 5, the hood lock device 80 can be temporarily assembled to the upper layer 90 by a simple operation of fitting the arms 84 and 85 into the upper layer 90 (specifically, the slit 93 and the upper wall portion 92).

In embodiment 5, the length of the slit 93 is longer than the length of the lower arm 84 in the vehicle width direction, and therefore the lower arm 84 can move relatively in the vehicle width direction inside the slit 93. Further, since the length of the engagement hole 84A of the lower arm 84 in the vehicle width direction is longer than the length of the engagement projection 92A of the upper wall portion 92 in the vehicle width direction, the engagement projection 92A of the upper wall portion 92 can move relatively in the vehicle width direction inside the engagement hole 84A of the lower arm 84. Therefore, at this time, the hood lock device 80 is temporarily assembled to the upper deck 90, but is slidable in the vehicle width direction with respect to the upper deck 90.

In embodiment 5, the shapes of the arms 84, 85, the slit 93, and the upper wall portion 92 are determined so as to suppress the detachment of the fixing portions 81, 82 from the upper layer 90 and to allow the relative movement of the fixing portions 81, 82 with respect to the upper layer 90.

In embodiment 5, the distal end portion of the lower arm 84, the distal end portion of the upper arm 85, and the upper wall portion 92 are each formed in a plate shape extending in the vehicle width direction and the front-rear direction. When the cover lock device 80 is temporarily assembled to the upper layer 90, the upper wall portion 92 is sandwiched between the lower arm 84 and the upper arm 85. Therefore, the inner surfaces of the arms 84 and 85 of the fixing portions 81 and 82 (specifically, the lower surface of the upper arm 85 and the upper surface of the lower arm 84) can be configured to be in surface contact with the outer surface of the upper wall portion 92. In embodiment 5, the upper surface of the lower arm 84 and the lower surface of the upper wall portion 92 are in surface contact. This allows the upper layer 90 to support the fixing portions 81 and 82 in a stable state.

According to embodiment 5 described above, the following operational effect (8) is obtained in addition to the same effects as those described in (1) to (4) above.

(8) Since the upper surfaces of the lower arms 84 of the fixing portions 81 and 82 can be in surface contact with the lower surface of the upper wall portion 92 of the upper layer 90, the fixing portions 81 and 82 can be supported by the upper layer 90 in a stable state.

(embodiment 6)

Hereinafter, an assembly structure of the hood lock device according to embodiment 6 will be described with reference to fig. 17 and 18, focusing on differences from embodiment 1. In the following, the same components as those in embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Embodiment 6 differs from embodiment 1 only in the shape of the upper layer.

The shape of the upper layer of embodiment 6 will be described below.

As shown in fig. 17 and 18, a right pocket 101 for accommodating the right fixing portion 36 is erected at a position corresponding to the right fixing portion 36 on the front surface of the upper layer 100. The right pocket 101 is composed of a plate-shaped bottom wall 102 extending in the vehicle width direction and the front-rear direction on the lower side, a plate-shaped right wall 103 extending in the up-down direction and the front-rear direction on the right side, and a plate-shaped front wall 104 extending in the vehicle width direction and the up-down direction on the front side.

Further, a left side pocket 105 for housing the left side fixing portion 37 is provided at a position corresponding to the left side fixing portion 37 on the front surface of the upper layer 100. The left side pocket 105 is constituted by a plate-shaped bottom wall 106 extending in the vehicle width direction and the front-rear direction on the lower side, a plate-shaped left wall 107 extending in the up-down direction and the front-rear direction on the left side, and a plate-shaped front wall 108 extending in the vehicle width direction and the up-down direction on the front side.

The interval between the right wall 103 of the right bag 101 and the left wall 107 of the left bag 105 is longer than the interval between the right end of the right securing portion 36 and the left end of the left securing portion 37. A substantially rectangular through-hole (insertion hole 109) is formed in each of the front wall 104 of the right bag 101 and the front wall 108 of the right bag 101. These insertion holes 109 are provided at positions that come into contact with the front of the cap nut 22 of the upper layer 100. Further, a recess 109A is formed in the periphery of each insertion hole 109 of the front walls 104 and 108. The recess 109A has a substantially truncated quadrangular pyramid shape with the opening of the insertion hole 109 as the upper bottom.

Engaging protrusions 100A are provided on the front surface of the upper layer 100 so as to protrude above the right side pocket 101 and above the left side pocket 105. The lower surface of each of the engaging projections 100A is a flat surface extending in the vehicle width direction and the front-rear direction, and the projecting end surface of each of the engaging projections 100A is an inclined surface inclined so that the projecting amount of the engaging projection 100A increases downward. The distance between the bottom wall 102 of the right pocket 101 and the lower surface of the engaging projection 100A above the right pocket 101 is longer than the vertical length of the right fixing portion 36. The distance between the bottom wall 106 of the left side pocket 105 and the lower surface of the engaging projection 100A above the left side pocket 105 is longer than the vertical length of the left side fixing portion 37.

In embodiment 6, the right side fixing portion 36, the right side bag 101, the left side fixing portion 37, and the left side bag 105 correspond to a temporarily assembled portion for temporarily assembling the hood lock device 30 to the upper layer 100 by a fitting force.

Hereinafter, a series of operations for assembling the hood lock device 30 to the upper layer 100 and the operational effects thereof will be described in detail.

When the hood lock device 30 is temporarily assembled to the upper layer 100, the right fixing portion 36 is inserted into the right bag 101 from above, the right fixing portion 36 is fitted into the right bag 101, the left fixing portion 37 is inserted into the left bag 105 from above, and the left fixing portion 37 is fitted into the left bag 105.

When the cover lock device 30 is temporarily assembled to the upper layer 100, the rear surfaces of the fixing portions 36 and 37 abut against the corresponding engaging projections 100A. In this case, the projecting end surface of the engaging projection 100A is an inclined surface inclined so that the projecting amount of the engaging projection 100A becomes larger toward the lower side. Accordingly, the rear surfaces of the fixing portions 36 and 37 are configured so as not to be easily hooked by the corresponding engaging projection 100A, and therefore the fixing portions 36 and 37 can be smoothly fitted into the corresponding pockets 101 and 105.

When the corresponding fixing portions 36 and 37 are fitted into the respective bags 101 and 105, the front walls 104 and 108 of the bags 101 and 105 elastically deform so as to tilt forward. When the upper end of each of the fixing portions 36 and 37 passes through the corresponding engaging projection 100A, the corresponding front wall 104 or 108 is restored from elastic deformation. Accordingly, the fixing portions 36 and 37 are pressed from the rear by the inner surfaces of the front walls 104 and 108. Thus, the fixing portions 36 and 37 are sandwiched between the front surface of the upper layer 100 (specifically, the front surface of the cap nut 22) and the inner surfaces of the corresponding pockets 101 and 105, that is, fitted into the corresponding pockets 101 and 105. Therefore, the fixing portions 36 and 37 can be prevented from coming off the inside of the corresponding bags 101 and 105. Even if the cover lock device 30 is displaced upward, the upper ends of the fixing portions 36 and 37 abut against the lower surface of the engaging projection 100A, and therefore, the cover lock device 30 can be prevented from falling off from the upper layer 100.

As described above, according to embodiment 6, the cover lock device 30 can be temporarily assembled to the upper layer 100 by a simple operation of fitting the fixing portions 36 and 37 into the corresponding pockets 101 and 105.

In embodiment 6, the distance between the right wall 103 of the right pouch 101 and the left wall 107 of the left pouch 105 is longer than the distance between the right end of the right securing portion 36 and the left end of the left securing portion 37. Thus, the fixing portions 36 and 37 can move relatively in the vehicle width direction inside the respective bags 101 and 105. Therefore, at this time, although the hood lock device 30 is temporarily assembled to the upper deck 100, the hood lock device 30 is slidable in the vehicle width direction with respect to the upper deck 100.

In embodiment 6, the shapes of the bags 101 and 105 and the engaging projection 100A are determined so as to satisfy the requirements of suppressing the fixing portions 36 and 37 from coming out of the bags 101 and 105 and allowing the fixing portions 36 and 37 to move relative to the bags 101 and 105.

In the work of assembling the hood lock device 30 to the upper layer 100, the hood 12 is closed with the hood lock device 30 temporarily assembled to the upper layer 100 fixed to the vehicle 10, whereby the assembling position of the hood lock device 30 can be adjusted.

Then, the hood lock 30 is fixed to the upper layer 100. Specifically, the fixing bolt is inserted through the insertion hole 39 of the lower fixing portion 38 of the cover lock device 30 and is screwed with the cap nut 22 of the upper layer 100. Further, other bolts are inserted through the insertion holes 109 of the front wall 104 of the right pocket 101 and the insertion holes 39 of the right fixing portion 36, and are inserted through the cap nuts 22 of the upper layer 100. Further, other bolts are inserted through the insertion holes 109 of the front wall 104 of the left pocket 105 and the insertion holes 39 of the left fixing portion 37, and are inserted through the cap nuts 22 of the upper layer 100.

In embodiment 6, the peripheral edge of the insertion hole 109 of each front wall 104, 108 is a recessed portion 109A recessed in a substantially truncated quadrangular pyramid shape with the opening of the insertion hole 109 as the upper bottom. Therefore, when a bolt is inserted into each of the insertion holes 109 of the front walls 104 and 108, the tip end of the bolt is guided to the opening of the insertion hole 109 by the inner surface of the recess 109A. Therefore, the work of fixing the hood lock device 30 to the upper layer 100 by bolt fastening can be easily performed.

According to embodiment 6 described above, the same effects as those described in (1) to (4) above can be obtained.

(7 th embodiment)

Hereinafter, an assembly structure of the hood lock device according to embodiment 7 will be described with reference to fig. 19 and 20, focusing on differences from embodiment 1. In the following, the same components as those in embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Embodiment 7 differs from embodiment 1 only in the shape of the upper layer.

The shape of the upper layer of embodiment 7 will be described below.

As shown in fig. 19 and 20, a gate-shaped engaging portion 114, which is formed by a pair of side walls (specifically, a right side wall 111 and a left side wall 112) and a front wall 113 connecting the pair of side walls 111 and 112, protrudes from the front surface of the upper layer 110 at a position corresponding to the cover lock device 30. In embodiment 7, the engagement portion 114 corresponds to a temporarily assembled portion for temporarily assembling the hood lock device 30 to the upper layer 110 by an engagement force.

The right side wall 111 extends in the front-rear direction at a position on the right side of the base 31 of the hood lock device 30 and on the lower side of the right fixing portion 36. The left side wall 112 extends in the front-rear direction at a position on the left side of the base 31 of the hood lock device 30 and on the lower side of the left fixing portion 37. The distance between the right side wall 111 and the left side wall 112 in the vehicle width direction is longer than the length of the base 31 of the hood lock device 30 in the vehicle width direction. Therefore, when the cover lock device 30 is fitted into the engaging portion 114 of the upper layer 110 in order to be temporarily assembled to the upper layer 110, a gap is formed between the outer surface of the base 31 and the inner surfaces of the side walls 111 and 112. In embodiment 7, when temporarily assembling the hood lock device 30 to the upper layer 110, the hood lock device 30 can be relatively moved in the vehicle width direction with respect to the upper layer 110 by the amount of the gap.

The front wall 113 extends in the vehicle width direction so as to connect the protruding ends of the two side walls 111, 112 to each other. When the cover lock device 30 is fitted into the engagement portion 114 of the upper layer 110, the rear surface of the right side portion and the rear surface of the left side portion of the front wall 113 contact the front surface of the base 31 of the cover lock device 30. In embodiment 7, the movement of the hood lock device 30 in the front-rear direction during temporary assembly is restricted by the contact between the rear surface of the front wall 113 and the front surface of the base 31 of the hood lock device 30.

The upper layer 110 has a plate-like bottom wall portion 115 extending in the front-rear direction and the vehicle width direction below the hood lock device 30. The bottom wall portion 115 is disposed at a position where an end of the lower fixing portion 38 of the hood lock device 30 abuts when the hood lock device 30 is assembled at a proper position. In embodiment 7, when the hood lock device 30 is temporarily assembled to the upper layer 110, the position of the hood lock device 30 in the vertical direction can be determined by bringing the lower fixing portion 38 of the hood lock device 30 into contact with the bottom wall portion 115 of the upper layer 110.

In embodiment 7, the work of temporarily assembling the cover lock device 30 to the upper layer 110 is performed such that the cover lock device 30 is inserted into the engaging portion 114 from above.

In the work related to this provisional assembly, the position of the hood lock device 30 in the vertical direction can be determined by an easy work of bringing the end portion of the lower fixing portion 38 of the hood lock device 30 into contact with the bottom wall portion 115 of the upper layer 110. In addition, when the hood lock device 30 is temporarily assembled to the upper layer 110, since the rear surface of the front wall 113 contacts the front surface of the base 31 of the hood lock device 30, the movement of the hood lock device 30 in the front-rear direction can be restricted by the contact. The distance between the two side walls 111, 112 in the vehicle width direction is greater than the length of the base 31 of the hood lock device 30 in the vehicle width direction. Therefore, even when the hood lock device 30 is temporarily assembled to the upper layer 110, the hood lock device 30 can be relatively moved in the vehicle width direction with respect to the upper layer 110 by the amount of the gap formed between the outer surface of the base 31 and the inner surfaces of the side walls 111 and 112.

In embodiment 7, the shape of the engaging portion 114 is determined so as to satisfy the requirements of suppressing the cover lock device 30 from coming out of the engaging portion 114 and allowing the cover lock device 30 to move relative to the engaging portion 114.

As described above, according to embodiment 7, the cover lock device 30 can be temporarily attached to the upper layer 110 by a simple operation of inserting the cover lock device 30 into the engaging portion 114 from above and fitting the cover lock device into the engaging portion 114.

According to embodiment 7 described above, the same effects as those described in (1) to (4) above can be obtained.

(embodiment 8)

Hereinafter, an assembly structure of the hood lock device according to embodiment 8 will be described with reference to fig. 21 to 23, focusing on differences from embodiment 1. In the following, the same components as those in embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In embodiment 8 and embodiment 1, the right and left securing portions of the cover lock device are different in shape from the upper layer.

The shapes of the right and left securing portions and the upper layer in embodiment 8 will be described below.

First, the right and left securing portions of embodiment 8 will be described.

As shown in fig. 21 to 23, the cover lock device 120 includes a right engaging piece 121, and the right engaging piece 121 is integrally formed with the right fixing portion 36 so as to protrude downward from the lower end of the right fixing portion 36. The cover lock device 120 includes a left engaging piece 122, and the left engaging piece 122 is integrally formed with the left fixing portion 37 so as to protrude downward from the lower end of the left fixing portion 37. These engaging pieces 121 and 122 have a substantially rectangular flat plate shape extending in the vehicle width direction and the vertical direction. The front surfaces of the engaging pieces 121 and 122 are subjected to rough surface processing (knurling processing in embodiment 8).

Next, the shape of the upper layer 130 according to embodiment 8 will be described.

A right bag portion 131 for accommodating the right engaging piece 121 and a left bag portion 132 for accommodating the left engaging piece 122 are provided to protrude from the front surface of the upper layer 130. Each pocket 131, 132 is formed by a bottom wall 133, a right wall 134, a left wall 135, and a front wall 136. The bottom wall 133 is shaped like a plate extending in the vehicle width direction and the front-rear direction below the corresponding pocket 131, 132, and the right wall 134 is shaped like a plate extending in the front-rear direction and the vertical direction on the right side of the corresponding pocket 131, 132. The left wall 135 is formed in a plate shape extending in the vertical direction and the front-rear direction on the left side of the corresponding pocket 131, 132, and the front wall 136 is formed in a plate shape extending in the vehicle width direction and the vertical direction on the front side of the corresponding pocket 131, 132.

Hereinafter, the operation of temporarily assembling the cover lock device 120 to the upper layer 130 and the operational effects thereof will be described together.

When the cover lock device 120 is temporarily assembled to the upper layer 130, the right engaging piece 121 integrated with the right fixing portion 36 is fitted into the right bag portion 131 from above, and the left engaging piece 122 integrated with the left fixing portion 37 is fitted into the left bag portion 132 from above.

Thus, the rear surfaces of the cover lock device 120 (specifically, the rear surface of the right-side fixing portion 36, the rear surface of the left-side fixing portion 37, and the rear surface of the lower-side fixing portion 38) are pressed against the front surface of the cap nut 22 of the upper layer 130. Further, the front surface of the cover lock device 120 (specifically, the front surface of the right engaging piece 121 and the front surface of the left engaging piece 122) is pressed against the rear surface of the front wall 136 of the bag portions 131 and 132. Therefore, at this time, the cover lock device 120 is sandwiched between the front surface of the upper layer 130 (the front surface of the cap nut 22) and the rear surfaces of the front walls 136 of the pockets 131 and 132.

Therefore, the engagement pieces 121, 122 can be prevented from coming out of the pockets 131, 132 and the cover lock device 120 can be prevented from coming out of the upper layer 130. In embodiment 8, as shown in fig. 23(a) and 23(b), the front surfaces of the engagement pieces 121 and 122, that is, the surfaces that come into contact with the rear surfaces of the front walls 136 of the bag portions 131 and 132, are subjected to rough surface processing. Thus, the engaging pieces 121 and 122 are configured to be less likely to come out of the pockets 131 and 132 than in the case where the front surfaces of the engaging pieces 121 and 122 are smooth surfaces.

As described above, according to embodiment 8, the cover lock device 120 can be temporarily assembled to the upper layer 130 by a simple operation of inserting the engaging pieces 121 and 122 integrated with the fixing portions 36 and 37 into the corresponding pocket portions 131 and 132 from above.

In embodiment 8, the right engaging piece 121, the right bag portion 131, the left engaging piece 122, and the left bag portion 132 correspond to a temporarily assembled portion for temporarily assembling the hood lock device 120 to the upper layer 130 by a fitting force.

In embodiment 8, the distance between the right wall 134 and the left wall 135 of each of the bag portions 131 and 132 is longer than the length of the corresponding engaging piece 121 or 122 in the vehicle width direction. Thus, the engaging pieces 121 and 122 can move relatively in the vehicle width direction inside the bag portions 131 and 132. Therefore, at this time, although the hood lock device 120 is temporarily assembled to the upper layer 130, the hood lock device 120 is slidable in the vehicle width direction with respect to the upper layer 130.

In embodiment 8, the shapes of the engaging pieces 121 and 122 and the bag portions 131 and 132 are determined so as to sufficiently prevent the engaging pieces 121 and 122 from coming out of the bag portions 131 and 132 and to allow the engaging pieces 121 and 122 in the bag portions 131 and 132 to move.

According to embodiment 8 described above, the same effects as those described in (1) to (4) above can be obtained.

(embodiment 9)

Hereinafter, an assembly structure of the hood lock device according to embodiment 9 will be described with reference to fig. 24 to 28, focusing on differences from embodiment 1. In the following, the same components as those in embodiment 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Hereinafter, a structure for assembling the cover lock device 30 to the upper layer 20 will be described.

The hood lock device 30 has three fixing portions 36, 37, 38 as portions fixed to the upper layer 20. Specifically, a right fixing portion 36 protruding to the right is provided on the right side of the chassis 31, a left fixing portion 37 protruding to the left is provided on the left side of the chassis 31, and a lower fixing portion 38 protruding downward is provided on the lower portion of the chassis 31. Each of these fixing portions 36, 37, and 38 has a substantially flat plate shape extending in the vertical direction and the vehicle width direction, and has an elongated hole-shaped insertion hole 39 extending in the vehicle width direction. Further, substantially rectangular through holes (fitting holes 40X) are provided in the right fixing portion 36 on the right side of the insertion hole 39 and in the left fixing portion 37 on the left side of the insertion hole 39, respectively.

Three cap nuts 22 having female threads are provided on the upper layer 20. The three cap nuts 22 correspond to the insertion holes 39 of the fixing portions 36, 37, 38 of the cover locking device 30. When the cover lock device 30 is fixed to the upper layer 20, the three bolts 15 (fig. 25) are inserted through the insertion holes 39 of the fixing portions 36, 37, and 38, and are screwed with the cap nuts 22, respectively. Thereby, the cover lock device 30 is fastened and fixed to the upper layer 20.

As shown in fig. 24 to 26, a right-side fitting projection 23X is provided on the front surface of the upper layer 20 so as to project at a position facing the fitting hole 40X of the right-side fixing portion 36. Further, a left-side fitting projection 24X is provided on the front surface of the upper layer 20 so as to project at a position facing the fitting hole 40X of the left-side fixing portion 37. When the cover lock device 30 is assembled to the upper layer 20, the right-side fitting projection 23X is inserted into the fitting hole 40X of the right-side fixing portion 36, and the left-side fitting projection 24X is inserted into the fitting hole 40X of the left-side fixing portion 37.

The right-side fitting projection 23X and the left-side fitting projection 24X have the same configuration. Specifically, each of the fitting convex portions 23X, 24X has a top wall 25X extending in the vehicle width direction and the front-rear direction on the upper side, a right wall 26X extending in the vertical direction and the front-rear direction on the right side, and a left wall 27X extending in the vertical direction and the front-rear direction on the left side, and is U-shaped. The front surface of the right wall 26X and the front surface of the left wall 27X are inclined surfaces inclined such that the distance from the front surface of the upper layer 20 becomes shorter toward the lower side.

In embodiment 9, the distance between the upper surface of the ceiling wall 25X and the lower end of the right wall 26X and the distance between the upper surface of the ceiling wall 25X and the lower end of the left wall 27X are substantially the same as the length of the fitting hole 40X in the vertical direction. The distance between the right side surface of the right wall 26X and the left side surface of the left wall 27X is shorter than the length of the fitting hole 40X in the vehicle width direction. Therefore, in a state (temporarily assembled state) in which the corresponding fitting convex portions 23X and 24X are fitted into the respective fitting holes 40X but the bolts 15 are not fastened and fixed, the respective fitting convex portions 23X and 24X are restricted from moving vertically inside the corresponding fitting holes 40X, and are allowed to move in the vehicle width direction. Thus, in the temporarily assembled state, the hood lock device 30 can slide in the vehicle width direction with respect to the upper layer 20.

The top wall 25X of the right-side fitting convex portion 23X and the top wall 25X of the left-side fitting convex portion 24X are provided at positions spaced apart in the vehicle width direction. Each top wall 25X has a pair of notches 25A extending forward from the rear end. A portion of top wall 25X sandwiched by the pair of cutout portions 25A is referred to as a spring portion 25B. The spring portion 25B is elastically deformable so as to be swingable in the vertical direction with respect to a peripheral edge portion surrounding the spring portion 25B. A convex portion (an engaging projection 25C) extending in the vehicle width direction is provided at an intermediate portion in the front-rear direction of an outer surface (an upper surface) of the spring portion 25B. As shown in fig. 27, when the cover lock device 30 is assembled to the upper layer 20, each engagement projection 25C extends in a state of being adjacent to an inner edge (opening edge) of the fitting hole 40X in the front surface of the corresponding fixing portion 36, 37. In embodiment 9, the spring portion 25B corresponds to an engagement portion.

Hereinafter, a series of operations for assembling the cover lock device 30 to the upper layer 20 and the operational effects thereof will be described in detail.

As shown in fig. 24 and 25, when the hood lock device 30 is assembled to the upper layer 20, first, the right-side fitting projection 23X is fitted into the fitting hole 40X of the right-side fixing portion 36, and the left-side fitting projection 24X is fitted into the fitting hole 40X of the left-side fixing portion 37. Specifically, as shown by the hollow arrows in fig. 27, the spring portions 25B are elastically deformed so as to enter the fitting convex portions 23X and 24X, and the fitting convex portions 23X and 24X are inserted into the corresponding fitting holes 40X. After the fixing portions 36 and 37 pass the engaging projections 25C of the corresponding spring portion 25B, the spring portion 25B is restored from the elastically deformed state. Accordingly, the engaging projection 25C of each spring portion 25B is hooked on the inner edge of the fitting hole 40X in the front surface of the corresponding fixing portion 36, 37 (the state shown in fig. 27). That is, each engaging projection 25C engages with the inner edge of the corresponding engaging hole 40X. Accordingly, the fitting projections 23X, 24X can be prevented from coming off the fitting hole 40X, and the cover lock device 30 can be prevented from coming off the upper layer 20. As described above, according to embodiment 9, the hood lock device 30 can be temporarily assembled to the upper layer 20 by a simple operation of fitting the fitting projections 23X and 24X into the fitting hole 40X.

In embodiment 9, a right-side fixing portion 36 (fitting hole 40X) is provided in a right-side portion of the hood lock device 30 (fig. 24). The upper layer 20 is provided with a right fitting projection 23X corresponding to the right securing portion 36. A left-side fixing portion 37 (fitting hole 40X) is provided in a left portion of the hood lock device 30. The upper layer 20 is provided with a left fitting projection 24X corresponding to the left securing portion 37. Therefore, when the hood lock device 30 is temporarily assembled to the upper layer 20, both side portions of the hood lock device 30 are supported by the upper layer 20. Therefore, the cover lock device 30 can be supported in a stable state by the upper layer 20.

In addition, the following is assumed: the upper layer 20 with the hood lock device 30 temporarily assembled in this manner is transported to an assembly factory where the vehicle 10 is assembled, or transported to a workshop in a next step in the assembly factory. According to embodiment 9, the cover lock device 30 is attached to the upper layer 20 by fitting the fitting hole 40X of each of the fixing portions 36 and 37 and the corresponding fitting convex portions 23X and 24X. Therefore, when the upper layer 20 in a state where the cover lock device 30 is temporarily assembled is conveyed, the cover lock device 30 can be prevented from being detached from the upper layer 20.

Next, the assembling position of the hood lock device 30 is adjusted. Specifically, the hood 12 is closed in a state where the hood lock device 30 is temporarily assembled to the upper layer 20 fixed to the vehicle 10.

In this case, first, the hook 13A of the cover striker 13 abuts against the upper end surface 34B of the hook 34A of the catcher 33. The upper end surface 34B of the hook 34A is an inclined surface extending downward as it faces the projecting end. Therefore, when the hook portion 13A of the cover striker 13 abuts against the upper end surface 34B, the catcher 33 is rotated counterclockwise in the front view by the pressing of the hook portion 13A of the cover striker 13. Thereby, the hook portion 13A of the cover striker 13 enters the inside of the notch portion 31A of the chassis 31 so as to push open the hook portion 34A of the catcher 33.

Fig. 28 shows a positional relationship between the base 31 of the hood lock device 30 and the hook portion 13A of the hood striker 13 in a case where the temporary assembly position of the hood lock device 30 is shifted to the left (right in fig. 28). As shown in fig. 28, in this case, hook portion 13A of cover striker 13 abuts on the right side (left side in fig. 28) surface of the inner surface of notch portion 31A of base 31. Here, as described above, the hood lock device 30 can move in the vehicle width direction with respect to the upper deck 20 even in the state of being temporarily assembled to the upper deck 20. Therefore, when the hook portion 13A of the hood striker 13 abuts against the inner surface (specifically, the right surface) of the cutout portion 31A and presses the inner surface of the cutout portion 31A, the hood lock device 30 moves to the right relative to the upper layer 20 as indicated by the solid arrow in fig. 28. On the other hand, when the temporary assembly position of the hood lock device 30 is shifted to the right, the hook portion 13A of the hood striker 13 abuts against and presses the left inner surface of the inner surfaces of the notch portions 31A, and the hood lock device 30 moves to the left with respect to the upper layer 20. On the other hand, in the case where the temporary assembly position of the hood lock device 30 is within the allowable range, when the hood 12 is closed, the hood lock device 30 does not move relative to the upper layer 20.

By closing the cover 12 in the state where the cover lock device 30 is temporarily assembled to the upper layer 20 in this way, the position of the cover lock device 30 in the vehicle width direction is a position that does not prevent the hook portion 13A of the cover striker 13 from smoothly entering the notch portion 31A of the base 31.

Then, the hood lock 30 is fixed to the upper layer 20. Specifically, the three fixing bolts 15 (fig. 25) are inserted through the insertion holes 39 of the fixing portions 36, 37, and 38 of the cover lock device 30, and are screwed with the cap nuts 22 of the upper layer 20. Thereby, the cover lock device 30 is fastened and fixed to the upper layer 20. In embodiment 9, the cover locking device 30 can be fastened and fixed by the bolt 15 in the state in which the cover 12 is locked in the closed state.

According to embodiment 9, the hood lock device 30 can be temporarily assembled to the upper layer 20 by a simple operation of fitting the corresponding fitting convex portions 23X, 24X of the upper layer 20 into the fitting holes 40X of the fixing portions 36, 37 of the hood lock device 30. Thus, before the hood lock device 30 is fixed to the upper layer 20, the hood lock device 30 can be supported by the upper layer 20. In this temporarily assembled state, the position of the hood lock device 30 in the vehicle width direction can be adjusted by the operation of moving the hood lock device 30 relative to the upper deck 20. As described above, according to embodiment 9, the work of temporarily assembling the hood lock device 30 and the work of adjusting the position can be easily performed, and therefore the work of assembling the hood lock device 30 can be easily performed.

In the 9 th embodiment, the upper layer 20 of the radiator core support 14 is formed by a synthetic resin material. Generally, the upper layer 20 made of synthetic resin is more likely to have larger manufacturing errors than the upper layer made of metal. Therefore, in the assembly structure of embodiment 9 in which the cover lock device 30 is fixed to the upper layer 20 made of synthetic resin, there is a possibility that the relative positions of the cover lock device 30 and the cover striker 13 are deviated. According to embodiment 9, in the assembly structure in which the hood lock device 30 is fixed to the synthetic resin upper layer 20, the position of the hood lock device 30 in the vehicle width direction can be adjusted, and the assembly work of the hood lock device 30 can be easily performed.

As described above, according to embodiment 9, the following effects are obtained in addition to the effects similar to the effects described in (1), (2), and (4) above.

(9) The fitting convex portions 23X, 24X are inserted into the fitting holes 40X, respectively, while elastically deforming the spring portions 25B having the engaging projections 25C. Accordingly, the hood lock device 30 can be temporarily assembled to the upper layer 20 so that the engagement projection 25C engages with the inner edge of the engagement hole 40X. By the engagement of the engaging projections 25C and the inner edge of the fitting hole 40X, the fitting projections 23X and 24X can be prevented from coming off the fitting hole 40X, and the cover lock device 30 can be prevented from coming off the upper layer 20.

(embodiment 10)

Hereinafter, an assembly structure of a hood lock device according to embodiment 10 will be described with reference to fig. 29 and 30, focusing on differences from embodiment 9. In the following, the same components as those in embodiment 9 are denoted by the same reference numerals, and detailed description thereof will be omitted.

The 10 th embodiment and the 9 th embodiment differ only in the shape of the right-side fitting projection.

The right-side fitting projection of embodiment 10 will be described below.

As shown in fig. 29 and 30, the right-side fitting projection 51X includes a cylindrical portion 52X extending in a cylindrical shape in the front-rear direction and four ribs 53X provided on the outer peripheral surface of the cylindrical portion 52X. The four ribs 53X are arranged at 90-degree intervals in the circumferential direction of the outer peripheral surface of the cylindrical portion 52X, and extend radially. Among the four ribs 53X, the rib 53X disposed above is referred to as an upper rib 53A, and the rib 53X disposed below is referred to as a lower rib 53B. The upper rib 53A and the lower rib 53B extend in the vertical direction, and the distance between the upper surface of the upper rib 53A and the lower surface of the lower rib 53B is substantially the same as the vertical length of the fitting hole 40X. When the cover lock device 30 is assembled to the upper layer 50X, the right-side fitting projection 51X is inserted into the fitting hole 40X of the right-side fixing portion 36.

In a state where the right fitting convex portion 51X is fitted into the fitting hole 40X of the right fixing portion 36 and the bolt 15 is not fastened and fixed (a temporarily assembled state), the right fitting convex portion 51X is restricted from moving vertically inside the fitting hole 40X and is allowed to move in the vehicle width direction. Therefore, in the temporarily assembled state, the hood lock device 30 can slide in the vehicle width direction with respect to the upper layer 50X.

According to embodiment 10, the same effects as those described in (1), (2), (4), and (9) above can be obtained.

(embodiment 11)

Hereinafter, an assembly structure of the hood lock device according to embodiment 11 will be described with reference to fig. 31 and 32, focusing on differences from embodiments 9 and 10. In the following, the same components as those in embodiments 9 and 10 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Embodiment 11 differs from embodiments 9 and 10 only in the shape of the right-side fitting projection and the left-side fitting projection.

The shapes of the right-side fitting projection and the left-side fitting projection of embodiment 11 will be described below.

As shown in fig. 31 and 32, the right-side fitting projection 61X and the left-side fitting projection 62X have the same configuration. Each of the fitting projections 61X, 62X has: a plate-shaped lower wall 63X extending in the front-rear direction and the vehicle width direction on the lower side; a front wall 64X having a plate shape and extending in the vertical direction and the vehicle width direction on the front side; and a plate-shaped upper wall 65X extending in the front-rear direction and the vehicle width direction on the upper side. The lower wall 63X is provided protruding from the front surface of the upper layer 60X. The front wall 64X protrudes upward from the front end of the lower wall 63X. The upper wall 65X protrudes rearward from the upper end of the front wall 64X.

The distance in the vertical direction between the lower surface of the lower wall 63X and the upper surface of the upper wall 65X is shorter than the length in the vertical direction of the fitting hole 40X. Thereby, the fitting convex portions 61X and 62X can be inserted into the corresponding fitting holes 40X. Further, a gap is formed between the rear end of the front wall 64X and the front surface of the upper layer 60X. The length of the gap between the rear surface of the upper wall 65X and the front surface of the upper layer 60X in the front-rear direction is substantially the same as the thickness of the fixing portions 36, 37.

When the cover lock device 30 is assembled to the upper layer 60X, the right-side fitting projection 61X is inserted into the fitting hole 40X of the right-side fixing portion 36, and the left-side fitting projection 62X is inserted into the fitting hole 40X of the left-side fixing portion 37.

Specifically, first, the right-side fitting projection 61X is inserted into the fitting hole 40X of the right-side fixing portion 36, and the left-side fitting projection 62X is inserted into the fitting hole 40X of the left-side fixing portion 37. Then, each fixing portion 36, 37 is entered between the rear surface of the upper wall 65X and the front surface of the upper layer 60X in each fixing portion 36, 37. That is, the cover lock device 30 moves downward relative to the upper layer 60X. Accordingly, the upper surface of the inner surface of each fitting hole 40X comes into contact with the upper surface of the lower wall 63X of the corresponding fitting projection 61X, 62X, and the portion of each fixing portion 36, 37 above the corresponding fitting hole 40X is fitted between the rear surface of the upper wall 65X and the front surface of the upper layer 60X (fig. 31).

In embodiment 11, by fitting the right fitting projection 61X into the fitting hole 40X of the right fixing portion 36 and fitting the left fitting projection 62X into the fitting hole 40X of the left fixing portion 37, the corresponding fitting projections 61X and 62X are prevented from coming off from the fitting holes 40X. This can prevent the cover lock device 30 from falling off from the upper layer 60X. As described above, according to embodiment 11, the cover lock device 30 can be temporarily assembled to the upper layer 60X by a simple operation of fitting the corresponding fitting projections 61X, 62X into the fitting holes 40X of the respective fixing portions 36, 37.

In embodiment 11, the length of each of the fitting convex portions 61X, 62X in the vehicle width direction is shorter than the length of the fitting hole 40X of the corresponding fixing portion 36, 37 in the vehicle width direction. Thus, in the temporarily assembled state, the fitting convex portions 61X and 62X are restricted from moving vertically within the fitting holes 40X of the corresponding fixing portions 36 and 37, and are allowed to move in the vehicle width direction. Therefore, in the temporarily assembled state, the hood lock device 30 is slidable in the vehicle width direction with respect to the upper layer 60X.

According to embodiment 11, the same effects as those described in (1), (2), (4), and (9) above can be obtained.

(other embodiments)

The above embodiments may be modified as follows.

In each embodiment, the position of the cover lock device may be adjusted by any operation. That is, the position adjustment of the cover lock device by closing the cover in a state where the cover lock device is temporarily assembled to the upper layer is merely an example. For example, the cover lock device may be moved by a hand of an operator while visually checking the relative positions of the cover striker and the cover lock device.

In embodiment 2, the cross-sectional shape of each of the pair of right engaging pieces 41 and the pair of left engaging pieces 45 as viewed in the vehicle width direction may be a wave shape, a crank shape, or a rectangular wave shape. According to such a configuration, as compared with the case where the engaging pieces are flat, the bent portions of the engaging pieces 41 and 45 can be made longer, and the engaging pieces 41 and 45 can be easily bent.

In the pair of right engaging pieces and the pair of left engaging pieces in embodiments 1 to 3, the thickness of the upper engaging piece and the thickness of the lower engaging piece may be the same, or the lower engaging piece may be thinner than the upper engaging piece.

In any of embodiments 1 to 6 and 8, the temporary assembly portion may be provided only on one of the right and left sides of the cover lock device. For example, when the temporarily assembled portion is provided only on one side of the hood lock device, a support portion that supports the hood lock device (specifically, the fixing portion) from below may be provided on the other side of the hood lock device. With such a configuration, the following can be suppressed: when the hood lock device is temporarily assembled, the hood lock device is inclined so that a portion of the hood lock device where the temporarily assembled portion is not provided is lowered downward by the weight of the hood lock device or an impact when the hood is closed.

For example, the temporary assembly portion of embodiment 1 may be provided on the right side of the hood lock device, and the temporary assembly portion of embodiment 2 may be provided on the left side. The two different temporary assembling portions in embodiments 1 to 6 and 8 to 11 may be combined.

In embodiment 9, the structure for suppressing the corresponding fitting protrusions 23X, 24X from coming off from the fitting holes 40X of the respective fixing portions 36, 37 may be appropriately modified. That is, the fitting convex portions 23X and 24X may have a structure other than the spring portion 25B and the engaging projection 25C. As an example of such a structure, a structure in which grooves (fitting grooves) extending along the front surface of the upper layer 20 are provided at the base end of the upper surface and the base end of the lower surface of the fitting projections 23X and 24X, respectively, can be given. In this case, the distance in the vertical direction between the upper surface and the lower surface of the fitting convex portions 23X and 24X may be slightly larger than the length in the vertical direction of the fitting hole 40X. In this case, the distance in the vertical direction between the bottom surface of the fitting groove in the upper portion and the bottom surface of the fitting groove in the lower portion of the fitting convex portions 23X and 24X may be substantially the same as the length in the vertical direction of the fitting hole 40X. According to such a configuration, the inner edges of the fitting holes 40X can be fitted into the fitting grooves of the fitting convex portions 23X, 24X by pushing the fitting convex portions 23X, 24X into the fitting holes 40X until the inner edges of the fitting holes 40X are fitted into the fitting grooves, and therefore, the fitting convex portions 23X, 24X can be prevented from coming off from the fitting holes 40X.

In embodiment 9, the fitting convex portion (the right fitting convex portion 23X or the left fitting convex portion 24X) may be provided only on one of the right and left sides of the upper layer, and the fitting hole (the fitting hole 40X of the right fixing portion 36 or the fitting hole 40X of the left fixing portion 37) may be provided only on one of the right and left sides of the hood lock device. That is, one of the fitting hole 40X of the right fixing portion 36 and the fitting hole 40X of the left fixing portion 37 may be omitted. In this case, a support portion for supporting the hood lock device (specifically, the fixing portion) from below may be provided in a portion of the hood lock device where the fitting hole is not provided. With such a configuration, the following can be suppressed: when the hood lock device is temporarily assembled, the hood lock device is inclined so that a portion of the hood lock device where the temporarily assembled portion is not provided is lowered downward by the weight of the hood lock device or an impact when the hood is closed.

In embodiment 10, the vertical interval between the upper surface and the lower surface of the right-side fitting projection 51X is set to be substantially equal to the vertical length of the fitting hole 40X of the right-side fixing portion 36, and the shape of the right-side fitting projection 51X can be arbitrarily changed. As such a right-side fitting projection, for example, a structure extending in a cylindrical shape in the front-rear direction, a structure extending in an I-shape in cross section, a structure extending in a circular shape in cross section, a structure extending in a cross-shape in cross section, a structure extending in an H-shape in cross section, or the like can be adopted.

In each embodiment, a fitting hole extending in the vehicle width direction may be formed in the upper layer, and a fitting protrusion protruding toward the upper layer and fitted into the fitting hole so as to be movable in the vehicle width direction may be formed in the fixing portion of the hood lock device.

The assembly structure of each of the above embodiments can also be applied to a cover lock device that is fixed to the upper layer of the radiator core support with an intervening member (a dedicated bracket or the like). In this case, the interposed member corresponds to the assembly portion.

The assembly structure according to each of the above embodiments can be applied to a cover lock device fixed to a metal upper layer.

The assembly structure of each of the above embodiments can also be applied to a hood lock device that is fixed to a portion (e.g., a cross member) other than the radiator core support in the vehicle body. That is, the assembly portion may be provided in the vehicle body or one of a plurality of components constituting the vehicle body.
