Technical Field

The technology described in the present specification relates to a snap structure.

Background

An engagement structure in which a convex portion of a door panel is fitted into a concave portion of a door trim is known. In this engagement structure, when the locking claw of the door trim is inserted into the hole provided in the door panel and the locking claw of the door trim is locked to a portion of the hole edge of the hole of the door panel, which portion is opposed to the convex portion of the door panel, the convex portion of the door panel is fitted into the concave portion of the door trim. An example of such an engagement structure is disclosed in japanese patent application laid-open No. 2009-222108. With such an engagement structure, the state in which the door trim is attached to the door panel is stabilized.

Disclosure of Invention

Problems to be solved by the invention

However, since the door panel has high rigidity and is difficult to bend, a high insertion force is required when the locking claw is inserted into the hole. In order to reduce the insertion force, it is also conceivable to increase the dimension of the locking claw in the protruding direction, but the space on the back side of the door panel where the locking claw is disposed is generally designed to be as small as possible, and there is a problem that the dimension of the locking claw in the protruding direction cannot be increased. Further, when a force in a direction opposite to the insertion direction of the locking claw into the hole portion of the door panel is applied to the door trim, there is a possibility that the hole edge portion of the hole portion of the door panel, which the locking claw contacts, is deformed in a direction away from the locking claw, and there is a risk that the locking claw is easily disengaged from the door panel.

The technology described in the present specification has been made in view of the above circumstances, and an object thereof is to provide an engaging structure that is compact and can achieve engagement between members without requiring a high insertion force.

Means for solving the problems

The engagement structure between the 1 st member and the 2 nd member includes a locking claw and a receiving portion. The locking claw protrudes from a 2 nd member opposing surface of the 1 st member opposing the 2 nd member toward the 2 nd member. The receiving portion protrudes from an opposite surface of the 2 nd member on the opposite side to the 2 nd member opposing surface in a direction opposite to the 2 nd member opposing surface, and has a receiving space therein communicating with a through hole formed in the 2 nd member. The receiving and accommodating portion includes a locking portion, a supporting portion, and two slits. The locking portion is formed in a plate shape protruding from the opposite surface. The support portion protrudes from the opposite surface so that at least a part of an inner surface of the support portion faces an inner surface of the locking portion, and supports the locking claw. The slit is provided between two end edges of the locking portion extending in the protruding direction and end edges of the support portion adjacent to the end edges of the locking portion, respectively, and the slit is connected to the housing space. The housing space is defined by the locking portion and the support portion. A part of the locking claw is disposed in the housing space, and the other part of the locking claw is engaged with the locking portion.

In the above-described engagement structure, since the engagement portion is separated from the support portion by the slit, the engagement portion is easily bent, and when the engagement claw is inserted into the housing space, the engagement portion is pushed up by the engagement claw, the housing space is enlarged, and the engagement claw is more easily inserted into the housing space. That is, the engagement structure can engage the locking claw with a lower insertion force to the locking portion than an engagement structure including a receiving portion without a slit. Further, since the locking portion is easily bent, the locking claw can be inserted into the housing space with a low insertion force without increasing the dimension of the locking claw in the protruding direction.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the technology described in the present specification, it is possible to provide an engaging structure that is compact and can achieve engagement between components without requiring a high insertion force.

Detailed Description

< embodiment 1 >

Embodiment 1 will be described with reference to fig. 1 to 9.

As shown in fig. 1, the vehicle door 1 includes a door panel 2, a door trim 10 (1 st member), and a garnish 30 (2 nd member). The door trim 10 is provided so as to cover the lower inner surface of the door panel 2. The garnish 30 is attached to the door trim 10 so that a part thereof is exposed from the back side of the door trim 10 to the front side of the door trim 10, and constitutes a part of the exterior surface of the door trim 10. The door trim 10 includes a plurality of locking claws 11 that protrude in the Z-axis direction from a back surface 10A (No. 2 member-facing surface) facing the garnish 30 toward the garnish 30. As shown in fig. 1 and 2, the garnish 30 includes a plurality of receiving portions 31 that protrude in a direction opposite to the back surface 10A from the back surface 30A (opposite surface) on the side opposite to the back surface 10A. The receiving portions 31 are disposed at positions corresponding to the locking claws 11, and each receiving portion 31 has a receiving space 34 in the interior thereof, in which the corresponding locking claw 11 can be received. A through hole 34A communicating with the housing space 34 is formed in the garnish 30 at a position corresponding to the housing space 34, and serves as an insertion port for inserting the locking claw 11 into the housing space 34. The locking claw 11 is inserted into the housing space 34 along the Z-axis direction.

As shown in fig. 2 and 5, the receiving portion 31 includes the locking portion 32, the support portion 33, and two slits 35. The locking portion 32 is formed in a plate shape protruding from the back surface 30A. The locking portion 32 has a base end portion connected to the back surface 30A and a protruding end portion 36 located on the opposite side of the base end portion and including an end edge (protruding end edge) in the protruding direction of the locking portion 32. The support portion 33 is formed in a horizontally long U-shape protruding from the back surface 30A in the Z-axis direction so that at least a part of the inner surface thereof faces the inner surface of the engaging portion 32. The locking portion 32 is separated from the support portion 33 in the Y axis direction, and is inclined such that the protruding end portion 36 is closer to the support portion 33 than the base end portion. The housing space 34 is a space surrounded by the locking portion 32 and the support portion 33, and the support portion 33 defines substantially half of the housing space 34. The locking portion 32 has a 1 st edge and a 2 nd edge extending in the projecting direction thereof, and slits 35 are provided between the 1 st edge and an edge of the support portion 33 adjacent to the 1 st edge, and between the 2 nd edge and an edge of the support portion 33 adjacent to the 2 nd edge, respectively.

The locking claw 11 includes a main body 25, a convex portion 12, two 1 st ribs 27, two 2 nd ribs 28, and two 3 rd ribs 26. The main body 25 protrudes in a direction (Z-axis direction) from the rear surface 10A toward the garnish 30. As shown in fig. 7, the main body 25 has a base end portion 25A disposed between the back surface 10A and the garnish 30, an intermediate portion 25B disposed in the housing space 34, and a protruding end portion 25C disposed outside the housing space 34 on the side away from the back surface 10A. As shown in fig. 2 and 3, the locking claw 11 has a 1 st surface 17 (a locking portion facing surface), two 2 nd surfaces 18, a 3 rd surface 16 (a support portion facing surface), and a convex portion 12. As shown in fig. 7, in a state where the locking claw 11 is inserted into the housing space 34, the region of the intermediate portion 25B in the 1 st surface 17 faces the locking portion 32, and the region of the intermediate portion 25B in the 3 rd surface 16 faces the support portion 33. The 2 nd surface 18 is disposed between the 1 st surface 17 and the 3 rd surface 16 at the end edges extending in the Z-axis direction. The convex portion 12 protrudes from the region of the protruding end portion 25C in the 1 st surface 17. Further, a recess 20A recessed from the 1 st surface 17 toward the 3 rd surface 16 is provided between the convex portion 12 of the locking claw 11 and the back surface 10A (the base end portion 25A and the intermediate portion 25B). The projecting end 25C of the locking claw 11 is provided with a recess 20C that is recessed from the 1 st surface 17 toward the 3 rd surface 16.

As shown in fig. 2 to 4, 7, and 9, the locking claw 11 includes two 1 st ribs 27, two 2 nd ribs 28, and two 3 rd ribs 26. Each of the 1 st ribs 27 is a plate-like portion protruding from the 1 st surface 17 at the base end portion 25A, and is connected to the rear surface 10A. Each of the 2 nd ribs 28 is a plate-shaped portion protruding from a portion of the corresponding 2 nd surface 18 close to the back surface 10A in the X-axis direction (a direction orthogonal to the protruding direction of the locking claw 11 and the direction in which the locking portion 32 is separated from the support portion 33), and is connected to the back surface 10A. Each of the 3 rd ribs 26 is a plate-like portion protruding from a portion of the 3 rd surface 16 close to the rear surface 10A, and is connected to the rear surface 10A.

As shown in fig. 3 and 8, the convex portion 12 has a 1 st inclined surface 13 (abutment surface), a 2 nd inclined surface 14, and a top surface 15. The top surface 15 is a top surface of the convex portion 12 and extends in the X-axis direction. The top surface 15 has a 1 st end edge and a 2 nd end edge separated in the Z-axis direction (the projecting direction of the locking claw 11), the 1 st inclined surface 13 is inclined from the 1 st end edge of the top surface 15 close to the back surface 30A toward the 1 st surface 17, and the 2 nd inclined surface 14 is inclined from the 2 nd end edge far from the back surface 30A toward the 1 st surface 17 and the projecting end of the locking claw 11. For convenience of description, in a state where the locking portion 32 is in contact with the 1 st inclined surface 13 (see fig. 6 and 7), a relationship between an axis 37 of the locking portion 32 in the protruding direction and the normal 19 of the 1 st inclined surface 13 is shown in fig. 8 as a virtual view in which the locking portion 32 is separated from the 1 st inclined surface 13 in a direction along the axis 37. The axis 37 is inclined toward the 1 st surface 17 with respect to the normal 19 such that the protruding end side of the locking portion 32 is closer to the 1 st surface 17 than the base end side. The inclination of the axis 37 with respect to the normal line 19 may be about 1 degree.

As shown in fig. 1, when the garnish 30 is attached to the door trim 10, the locking claw 11 is first inserted into the accommodating space 34 in the receiving container 31. As shown in fig. 2 and 7, the distance in the Y-axis direction between the inner surface of the locking portion 32 and the inner surface of the support portion 33 is set smaller than the dimension from the 3 rd surface 16 to the top surface 15 of the convex portion 12 of the locking claw 11. Therefore, when the locking claw 11 is inserted into the receiving section 31, the locking claw 11 pushes up the locking section 32 by the 2 nd inclined surface 14 and enters the housing space 34. At this time, the locking claw 11 receives a reaction force in a direction from the locking portion 32 toward the support portion 33, but the 3 rd surface 16 is supported by the support portion 33, and therefore the locking portion 32 can be pushed up while overcoming the reaction force.

When the locking claw 11 is pushed until the convex portion 12 passes over the protruding end portion 36, as shown in fig. 5 to 7, the locking portion 32 is elastically restored, and the 1 st inclined surface 13 engages with the protruding end portion 36. That is, the locking claw 11 is engaged with the locking portion 32. This state is referred to as an engagement state between the locking claw 11 and the locking portion 32. When the locking claws 11 and the locking portions 32 are in the engaged state, the garnish 30 is mounted on the door trim 10. When the locking claw 11 and the locking portion 32 are in the engaged state, the 3 rd rib 26 abuts against the garnish 30, so that the locking claw 11 is held at an appropriate position with respect to the receiving container portion 31, and the engaged state of the locking claw 11 and the protruding end portion 36 can be stabilized.

Next, the effects of the present embodiment will be described. Since the locking portion 32 is separated from the support portion 33 by the slit 35, when pushed up by the locking claw 11 inserted into the housing space 34, the locking portion 32 is easily bent in a direction to expand the housing space 34. According to such a configuration, the insertion force required to insert the locking claw 11 into the housing space 34 is reduced as compared with an engagement structure including a receiving portion not provided with the slit 35. Since the locking portion 32 is separate from the support portion 33, the locking portion 32 can be inclined toward the support portion 33. According to such a configuration, even if a force acts to disengage the locking claw 11 from the housing space 34 when the locking claw 11 and the locking portion 32 are in the engaged state, the locking portion 32 can prevent the locking claw 11 from disengaging from the housing space 34. Therefore, the garnish 30 can be made less likely to detach from the door trim 10 than in the conventional engagement structure. Further, since it is not necessary to provide the locking claw 11 and the receiving section 31 with a large protruding dimension from the back surfaces 10A and 30A or to increase the width of the locking claw 11 in order to provide an engagement structure that is easy to insert and difficult to detach, a compact engagement structure can be provided as compared with a conventional engagement structure. Such an engagement structure can be applied to a narrow space.

When the locking claw 11 and the locking portion 32 are in the engaged state, when the locking claw 11 is to be pulled out, a force toward the support portion 33 acts on the protruding end portion 36, and the protruding end portion 36 is pressed toward the support portion 33. Therefore, the projecting end portion 36 can be prevented from sliding on the 1 st inclined surface 13 and causing the locking claw 11 to come out of the housing space 34. According to such an engagement structure, the garnish 30 can be more hardly detached from the door trim 10.

Since the 3 rd rib 26 is not provided in the region of the intermediate portion 25B of the 3 rd surface 16, the region of the intermediate portion 25B of the 3 rd surface 16 abuts against the support portion 33 when the locking claw 11 and the locking portion 32 are in the engaged state. If the 3 rd rib 26 is provided on both the base end portion 25A and the intermediate portion 25B of the 3 rd surface 16, the support portion 33 may be scraped by the 3 rd rib 26 when the locking claw 11 is inserted into the housing space 34. The 3 rd rib 26 of the present embodiment is provided only in the region of the base end portion 25A of the 3 rd surface 16, and therefore such a problem is hardly caused. Further, since the region of the intermediate portion 25B in the 3 rd surface 16 contacts the support portion 33, the frictional force increases, and the locking claw 11 is more difficult to be disengaged from the housing space 34. Further, since the 3 rd rib 26 is provided in the region of the base end portion 25A of the 3 rd surface 16, it is difficult for the base end portion 25A of the locking claw 11 to bend due to the reaction force received from the locking portion 32 when the locking claw 11 is inserted into the housing space 34.

< embodiment 2 >

Embodiment 2 is explained with reference to fig. 10. The engagement structure of the present embodiment includes the locking claw 211 and the receiving section 231 having different configurations from the locking claw 11 and the receiving section 31 of embodiment 1. In the description of the present embodiment, the same structure, operation, and effects as those of embodiment 1 may not be repeatedly described.

The receiving portion 231 of the garnish 230 (member 2) includes a locking portion 232, a support portion 233, a housing space 234, two slits 235, and two coupling portions 240. The locking portion 232 is formed in a plate shape protruding from the rear surface 230A (opposite surface). The locking portion 232 has a base end portion connected to the rear surface 230A and a protruding end portion 236 located on the opposite side of the base end portion and including an end edge (protruding end edge) in the protruding direction of the locking portion 232. The support portion 233 is formed in a horizontally long U-shape protruding from the back surface 230A in the Z-axis direction so that at least a part of the inner surface thereof faces the inner surface of the locking portion 232. The locking portion 232 is separated from the support portion 233 in the Y axis direction, and is inclined such that the protruding end portion 236 is closer to the support portion 233 than the base end portion. The housing space 234 is a space surrounded by the locked portion 232 and the support portion 233, and the support portion 233 defines substantially half of the housing space 234. The locking portion 232 has a 1 st edge and a 2 nd edge extending in the projecting direction thereof, and slits 235 are provided between the 1 st edge and an edge of the support portion 233 adjacent to the 1 st edge, and between the 2 nd edge and an edge of the support portion 233 adjacent to the 2 nd edge, respectively. The slit 235 is connected to the receiving space 234. A connecting portion 240 of the connecting portion 240 protrudes from the rear surface 230A of the garnish 230, and connects the 1 st end edge of the locking portion 232 and the end edge of the support portion 233 adjacent to the 1 st end edge. The other coupling portion 240 protrudes from the back surface 230A of the garnish 230, and couples the 2 nd end edge of the locking portion 232 and the end edge of the support portion 233 adjacent to the 2 nd end edge. The protruding dimension of the connecting portion 240 from the rear surface 230A is smaller than the protruding dimension of the locking portion 232 from the rear surface 230A and the protruding dimension of the support portion 233 from the rear surface 230A.

The degree of elastic deformation of the locking portion 232 in the Y-axis direction can be adjusted by adjusting the projection dimension of the coupling portion 240 from the back surface 230A in the Z-axis direction. Therefore, it is possible to adjust the balance between the insertion force required to insert the locking claw 211 into the housing space 234 and the holding force required to hold the locking claw 211 and the locking portion 232 in the engaged state.

The locking claw 211 of the door trim 210 includes a body 225, a convex portion 212, two 1 st ribs 227, and two 2 nd ribs 228. The main body 225 has a base end portion 225A, an intermediate portion 225B, and a protruding end portion 225C similar to the base end portion 25A, the intermediate portion 25B, and the protruding end portion 25C of the main body 25 of embodiment 1. The body 225 has a 1 st surface 217 (a surface facing the locking portion), two 2 nd surfaces 218, and a 3 rd surface 216 (a surface facing the support portion). The locking claw 211 includes a convex portion 212 having the same configuration as the convex portion 12 of embodiment 1, and the convex portion 212 protrudes from the region of the protruding end portion 225C in the 1 st surface 217. The 1 st rib 227 is formed in a plate shape protruding from a region of the base end portion 225A of the 1 st surface 217, and is connected to the rear surface 210A (the 2 nd member opposing surface). The 2 nd rib 228 is formed in a plate shape protruding from the 2 nd surface 218 in the X axis direction, and is connected to the rear surface 210A.

With such a configuration, the possibility of the support portion 233 being scraped off when the locking claw 211 is inserted into the housing space 234 can be further reduced as compared with embodiment 1. Further, the 1 st rib 227 and the 2 nd rib 228 reinforce the base end portion 225A of the locking claw 211, and therefore, it is difficult for the base end portion 225A of the locking claw 211 to bend due to a reaction force received from the locking portion 232 when the locking claw 211 is inserted into the housing space 234. Further, when the locking claw 211 and the locking portion 232 are in the engaged state, the 1 st rib 227 abuts on the garnish 230, so that the locking claw 211 is held in an appropriate position with respect to the receiving container 231, and the engaged state of the locking claw 211 and the locking portion 232 can be stabilized.

< embodiment 3 >

Embodiment 3 will be described with reference to fig. 11 and 12. The engagement structure of the present embodiment includes the locking claw 311 and the receiving container portion 331 having different configurations from the locking claw 11 and the receiving container portion 31 of embodiment 1 and the locking claw 211 and the receiving container portion 231 of embodiment 2. In the description of the present embodiment, the same structures, operations, and effects as those of embodiments 1 and 2 may be omitted from redundant description.

As shown in fig. 11, the locking claw 311 of the door trim 310 (the 1 st member) protrudes from the back surface 310A (the 2 nd member-facing surface) of the door trim 310, and includes a main body 325, two convex portions (the 1 st convex portion 312A and the 2 nd convex portion 312B), two 1 st ribs 327, and two 2 nd ribs 328. The main body 325 has a base end 325A, an intermediate portion 325B, and a protruding end 325C similar to the base end 25A, the intermediate portion 25B, and the protruding end 25C of the main body 25 of embodiment 1. The body 325 has a 1 st surface 317 (the locking portion facing surface), two 2 nd surfaces 318, and a 3 rd surface 316 (the support portion facing surface). The 1 st projection 312A projects from the area of the projecting end 325C in the 1 st face 317, and the 2 nd projection 312B projects from the area of the projecting end 325C in the 3 rd face 316.

The receiving portion 331 of the garnish 330 (member 2) includes a locking portion 332, a support portion 333, a housing space 334, and two slits 335. The locking portion 332 is formed in a plate shape protruding from the rear surface 330A (opposite surface), and has a 1 st protruding end portion 336. The support part 333 is formed in a plate shape protruding from the back surface 330A so that at least a part of the inner surface thereof faces the inner surface of the locking part 332, and has a 2 nd protruding end part 337. The housing space 334 is defined by the locking portion 332 and the support portion 333. A through hole 334A is formed in the garnish 330 at a position corresponding to the housing space 334, and serves as an insertion port for inserting the locking claw 311 into the housing space 334. The engaging portion 332 and the supporting portion 333 are inclined with respect to the Z-axis direction such that the distance between the 1 st projecting end portion 336 and the 2 nd projecting end portion 337 in the Y-axis direction is smaller than the dimension of the through hole 334A in the Y-axis direction. The locking portion 332 has a 1 st edge and a 2 nd edge extending in the projecting direction, and slits 335 are provided between the 1 st edge and an edge of the support portion 333 adjacent to the 1 st edge and between the 2 nd edge and an edge of the support portion 333 adjacent to the 2 nd edge, respectively, and the slits 335 are connected to the housing space 334.

As shown in fig. 12, the 1 st projection 312A has a 1 st inclined surface 313A (abutment surface), a 2 nd inclined surface 314A (abutment surface), and a top surface 315A. The top surface 315A has a 1 st end edge and a 2 nd end edge separated in the projecting direction of the locking claw 311, the 1 st inclined surface 313A is inclined from the 1 st end edge of the top surface 315A toward the 1 st surface 317, and the 2 nd inclined surface 314A is inclined from the 2 nd end edge of the top surface 315A toward the 1 st surface 317 and the projecting end of the locking claw 311. The 2 nd projection 312B has a 1 st inclined surface 313B (abutment surface), a 2 nd inclined surface 314B, and a top surface 315B. The top surface 315B has a 1 st end edge and a 2 nd end edge that are separated in the projecting direction of the locking claw 311, the 1 st inclined surface 313B is inclined from the 1 st end edge of the top surface 315B toward the 1 st surface 317, and the 2 nd inclined surface 314B is inclined from the 2 nd end edge of the top surface 315B toward the 1 st surface 317 and the projecting end of the locking claw 311. That is, when the locking claw 311 is viewed from the first 2 nd surface 318 side, the tip end has a shape like an arrow.

By configuring the locking claw 311 in this manner, the locking portion 332 and the support portion 333 can be configured to tilt toward each other. When the locking claw 311 is inserted into the housing space 334 and pushed until the 1 st and 2 nd convex portions 312A and 312B pass the 1 st and 2 nd protruding end portions 336 and 337, the locking portion 332 and the support portion 333 elastically return, the 1 st inclined surface 313A of the 1 st convex portion 312A engages with the 1 st protruding end portion 336, and the 1 st inclined surface 313B of the 2 nd convex portion 312B engages with the 2 nd protruding end portion 337. In a state (engaged state) in which the locking claw 311 is engaged with the locking portion 332, when a force acts to disengage the locking claw 311 from the housing space 334, the locking portion 332 and the support portion 333 are further inclined in a direction toward each other, and therefore, disengagement of the locking claw 311 from the housing space 334 can be suppressed.
