Further, the second feature is provided with: a single operation lever (60) which restricts the vertical movement of the battery (B) by being pressed downward in a state where the battery (B) is housed in the battery case (40); and a link mechanism (L) that connects the operating lever (60) and the terminal holder (74).

In addition, the third characteristic is that the operating lever (60) is configured to be slidable up and down along the longitudinal direction of the battery (B), and has a swing-type pressing bracket (45) that presses the upper surface (102) of the battery (60) when the operating lever (60) is moved to the lowermost position.

In addition, the battery case (40) is disposed below an openable seat (23) provided in the saddle-ride type vehicle (1), and a boss (84) positioned above the operating lever (60) is provided on the bottom surface of the seat (23).

Further, according to a fifth aspect, the boss (84) does not abut against the operating lever (60) in a state where the operating lever (60) is depressed to a predetermined lowermost position.

In addition, according to a sixth aspect of the present invention, the terminal holder (74) is a substantially U-shaped plate-like member covering a lower portion of the housing-side terminal (90), and a cylindrical support shaft (98) extending downward from a lower surface of the terminal holder (74) is inserted into a through hole (74a) formed in the terminal holder (74), whereby the terminal holder (74) and the housing-side terminal (90) are configured to be slidable in the vertical direction, and the spring (97) is a coil spring wound around the support shaft (98).

In addition, according to a seventh aspect, the support shaft (98) around which the spring (97) is wound is provided in a pair with the case-side terminal (90) therebetween.

Effects of the invention

According to a first aspect, a battery attachment/detachment structure for a saddle-ride type vehicle includes: a plurality of substantially rectangular parallelepiped batteries (B) that supply electric power to a power source of the saddle-ride type vehicle (1); a battery case (40) that houses the battery (B); a battery-side terminal (75) provided on the lower surface (107) of the battery (B); a case-side terminal (90) that engages with the battery-side terminal (75); the battery mounting/dismounting structure for a saddle-ride type vehicle is provided with a terminal bracket (74) which supports a case-side terminal (90) so as to be movable between a connection position (U) connected to the battery-side terminal (75) and a retreat position (D) separated from the battery-side terminal (75), wherein a spring (97) is arranged between the case-side terminal (90) and the terminal bracket (74), and the spring (97) applies a force in a direction in which the case-side terminal (90) is pressed against the case-side terminal (90), so that a pressing force which presses the case-side terminal against the battery-side terminal can be generated in a state in which the case-side terminal is moved to the connection position. Thus, even when the battery moves upward in the vehicle body, for example, when the battery passes over a large slope, the case-side terminal can be made to follow the movement of the battery and maintain the electrical connection.

According to the second feature, the present invention includes: a single operation lever (60) which restricts the vertical movement of the battery (B) by being pressed downward in a state where the battery (B) is housed in the battery case (40); and a link mechanism (L) for connecting the operating lever (60) and the terminal holder (74), so that the vertical movement of the battery can be restricted by a single operating lever, and the battery can be easily attached and detached. In addition, even when a minute dead stroke occurs in the operation of the operation lever due to the link mechanism including a plurality of rotary shafts, the housing-side terminal and the battery-side terminal can be absorbed by the spring after coming into contact with each other, and the preload can be effectively applied to the both terminals.

According to the third feature, the operation lever (60) is configured to be slidable vertically along the longitudinal direction of the battery (B), and has a swing-type pressing bracket (45) that presses the upper surface (102) of the battery (60) when the operation lever (60) is moved to the lowermost position, so that not only the case-side terminal is pressed against the battery-side terminal by the urging force of the spring but also the upper surface of the battery is pressed by the pressing bracket by pressing the operation lever downward, and the electrical connection between the terminals is easily maintained.

According to the fourth feature, the battery case (40) is disposed below an openable seat (23) provided in the saddle-type vehicle (1), and a boss (84) located above the operating lever (60) is provided on the bottom surface of the seat (23), so that the operating lever can be depressed by the boss when the seat is closed in a state where the operating lever is lifted upward from a predetermined lowermost position, and therefore the operating lever can be depressed by the boss when the seat is closed in a state where the operating lever is lifted upward from the predetermined lowermost position.

According to the fifth feature, since the boss (84) does not abut against the operating lever (60) in a state where the operating lever (60) is depressed to the predetermined lowermost position, the boss of the seat back portion is set to abut against the operating lever and be pushed into the minimum position when the operating lever is not depressed sufficiently at the time of closing the seat, and the boss does not abut against when the operating lever is depressed to the predetermined lowermost position, whereby it is possible to prevent a load from being further applied to the operating lever that is depressed sufficiently.

According to the sixth feature, the terminal holder (74) is a substantially U-shaped plate-like member covering the lower side of the case-side terminal (90), and a cylindrical support shaft (98) extending downward from the lower surface of the terminal holder (74) is inserted into a through hole (74a) formed in the terminal holder (74), whereby the terminal holder (74) and the case-side terminal (90) are configured to be slidable in the vertical direction, and the spring (97) is a coil spring wound around the support shaft (98), so that the case-side terminal can be biased toward the battery side with a simple structure.

According to the seventh feature, since the pair of support shafts (98) around which the spring (97) is wound are provided with the case-side terminal (90) interposed therebetween, the slide mechanisms of the terminal holders are provided on both sides of the case-side terminal, and therefore, the case-side terminal can be prevented from being tilted, and a smooth slide operation can be performed. This can maintain good electrical connection between the case-side terminal and the battery-side terminal.

According to the eighth aspect, two batteries (B) are arranged in line, a single operation lever (60) is provided, the single operation lever (60) is pressed downward in a state where the batteries (B) are housed in the battery case (40) to regulate the vertical movement of the batteries (B), and the terminal holders (74) provided on the two batteries (60) are coupled to the operation lever (60), so that the tolerance may be increased by providing terminal holders for the two batteries, respectively.

The terminal holder 74 is formed in a substantially U shape so as to surround the side surfaces of the battery B in the vehicle body longitudinal direction.

According to the above configuration, the link mechanism L having a structure including a "lever" based on the fulcrum, the force point, and the action point can be obtained. More specifically, the link mechanism L can be obtained in which the terminal holder 74 is raised when the operation lever 60 is pushed down and the terminal holder 74 is lowered when the operation lever 60 is pulled up, with the first swing shaft 71 as a fulcrum, the second swing shaft 68 as a force point, and the third swing shaft 72 as an action point. Further, by coupling the two terminal holders 74 to the link mechanism L, a structure in which the two terminal holders 74 are moved up and down by the single operation lever 60 can be obtained. Further, the terminal holder 74 can be moved up and down with a small force by utilizing the principle of leverage. The arm member 70 and the base plate 73 may be made of a thin plate-like metal.

Fig. 11 is a perspective view of the operating lever 60. The operating lever 60 for operating the link mechanism L is formed of a thin plate-like metal at a lower end portion 67 connected to one end portion of the arm member 70, and the upper side including the grip portion 61 and the partition portion 62 is formed of a hard synthetic resin or the like, thereby achieving weight reduction. In addition, the lower end portion 67 is deeply insert-molded in the longitudinal direction of the leg portion 66, so that the strength of the leg portion 66 can be improved.

Between the grip portion 61 and the partition portion 62, a grip opening 60a through which the occupant passes the fingers is formed. Further, a coupling portion 69 that couples the grip portion 61 and the dividing portion 62 is formed in the vehicle body front-rear direction of the grip opening 60 a. The left and right side surfaces of the connecting portion 69 in the vehicle width direction are formed in a tapered shape whose width is narrowed downward.

A side end surface 63a that abuts the tapered surface 51, which is the tapered side surface of the positioning recess 52, and an upper end surface 63b that abuts the lower portion of the pressing bracket 45 by pulling up the operating lever 60 and pushes up the same are formed on the positioning plate 63 extending in the vehicle width direction between the leg portion 66 and the dividing portion 62. A chamfered portion 63c is provided at a corner portion on the lower side of the positioning plate 63 which is substantially square in front view. Further, a stopper member 65 standing downward is formed at a lower portion of the pressing portion 64.

The side end surface 63a of the positioning plate 63 inserted into the positioning recess 52 has a tapered shape whose width is narrowed downward. Thus, by housing the positioning plate 63 in the positioning concave portion 52 provided with the tapered surface 51 functioning as a guide, the operating lever 60 can be smoothly held at the neutral position only by pressing down the operating lever 60. Further, by providing the chamfered portion 63c at the corner portion on the lower side of the positioning plate 63, the chamfered portion 63c comes into contact with the tapered surface 51 of the positioning concave portion 52 when the operation lever 60 is pushed down, and the operation of pushing down the operation lever 60 can be performed more smoothly.

Fig. 12 is a partially enlarged view of fig. 11. Fig. 13 is an enlarged perspective view showing the structure around the stopper member 65. As described above, both side surfaces of the connecting portion 69 in the vehicle width direction have a tapered shape whose width is narrowed as it goes downward. Thus, when battery B is pulled out upward from battery case 40, even if the upper end of battery B contacts operating lever 60, operating lever 69 can be smoothly retracted by the tapered shape of coupling portion 69, and battery B can be easily pulled out. Further, a stopper member 65 provided at a lower portion of the pressing portion 64 abuts against a top surface of the upper housing 41 positioned between the pressing brackets 45 on the left and right in the vehicle width direction, and defines a lowermost position of the operation lever 60. The stopper member 65 is provided with three weight-reduction recessed portions, and is formed in a substantially rectangular parallelepiped shape extending in the vehicle width direction.

Fig. 14 is a perspective view showing an XIV-XIV line section of fig. 4. Two batteries B are arranged in the vehicle width direction. The operating lever 60 is formed with a grip portion 61 that protrudes upward beyond the upper surface 102 of the battery B in a state where the battery B is housed in the battery case 40, and a partition portion 62 that is inserted between the batteries B in a state where the battery B is housed in the battery case 40. The dividing portion 62 is formed to be narrower than the width of the grip portion 61, and a grip opening 60a through which the occupant passes the fingers is formed between the grip portion 61 and the dividing portion 62. This prevents batteries B from interfering with each other by dividing portion 62, protects batteries B from impact, and improves the heat dissipation effect of batteries B. Further, by inserting a finger through the grip opening 60a, the wide grip portion 61 is easily gripped, and the attachment/detachment operation of the battery B is facilitated. The dividing portion 62 may be extended further downward to improve the insulating function between the batteries B.

Fig. 15 and 16 are front views showing the structure of the link mechanism L. Fig. 15 shows a state in which the operation lever 60 is pulled up, and fig. 16 shows a state in which the operation lever 60 is pushed down to a predetermined lowermost position. The pressing bracket 45 pivotally supported by the battery case 40 so as to be swingable is biased by an elastic member in a direction to press the upper surface of the battery B. Here, when the operating lever 60 is pulled up, the upper end surface 63b of the positioning plate 63 abuts against the lower surface of the pressing bracket 45, and the operating lever 60 is pulled up against the urging force of the elastic member, whereby the pressing bracket 45 swings upward and becomes an upright state. At the same time, the terminal holder 74 connected to the link mechanism L is lowered to the retracted position D by pulling up the operating lever 60, and the case-side terminals 90 are separated from the batteries B.

On the other hand, when the operating lever 60 is pushed down, the pressing bracket 45 swings in a direction of pressing the upper surface 102 of the battery B by the urging force of the elastic member. At the same time, when the operating lever 60 is pushed down, the terminal holder 74 connected to the link mechanism L is raised to the connection position U, and the case-side terminal 90 is connected to a battery-side terminal (see fig. 27) provided at the bottom of the battery B.

That is, by pressing down the single operation lever 60, the upper surfaces 102 of the two batteries B are pressed by the pressing brackets 45, and the case-side terminals 90 are engaged with the battery-side terminals provided on the lower surfaces of the batteries B, whereby the batteries B can be held so as to be sandwiched from above and below. This stably holds the battery B, and can maintain good electrical connection even when the battery B crosses a large slope. Further, since the two batteries B are held at the same time by holding the grip portion 61 positioned above the batteries B and pressing down the operating lever 60 and the operating lever 60 is pulled up to be in a state where the batteries B can be removed, the convenience of the operation of removing the batteries B can be improved.

The operating lever 60 is configured to be swingable about the second swing shaft 68 in a state where the operating lever 60 is pulled upward and the terminal holder 74 is moved to the retracted position D. Thus, even when the operation lever is disposed between two batteries disposed in proximity to each other, the operation lever 60 can be swung when the battery B is pulled out upward, thereby preventing interference with the battery B. Thus, the two batteries B can be disposed as close as possible, the space required for housing the batteries B can be reduced, and the battery case 40 can be downsized.

In the present embodiment, two batteries B are arranged in line in the vehicle width direction, and the first swing shaft 71, the second swing shaft 68, and the third swing shaft 72 are arranged at positions overlapping the batteries B when viewed from the front of the vehicle body, and therefore, the battery case 40 and the vehicle body can be downsized by arranging the link mechanism L at positions overlapping the batteries B when viewed from the front of the vehicle body.

Fig. 17 is a perspective view showing the pressing bracket 45 in a state where the operating lever 60 is pressed down to a predetermined lowermost position. Fig. 18 and 19 are perspective views of the pressing bracket 45 on the vehicle body rear side as viewed from the vehicle body rear side. Fig. 18 shows a state in which the upper surface 102 of the battery B is pressed, and fig. 19 shows a state in which the battery B rises upward in accordance with the pulling operation of the operation lever 60.

The pressing bracket 45 includes a main body portion 45c pivotally supported by the pivot shaft 45a, an elastic member 45d biasing in a direction to press the upper surface 102 of the battery B, and a pressing portion 45B fixed to the main body portion 45c and abutting against the upper surface 102 of the battery B. The main body 45c is formed of metal such as aluminum or hard synthetic resin, and the pressing portion 45b can be formed of resin such as rubber. A bottomed box-shaped interference portion 45e, with which the upper end surface 63b of the positioning plate 63 abuts from below, is provided on the vehicle width direction inner side of the main body portion 45 c. The elastic member 45d is a coil spring wound around the swing shaft 45a, and can apply a biasing force in one direction to the swing operation of the pressing bracket 45 with a simple structure.

Fig. 20 is a left side view of the pressing bracket 45 showing a state in which the operating lever 60 is pressed down to a predetermined lowermost position. In a state where the operation lever 60 is depressed, the interference portion 45e is formed in a shape protruding downward of the pressing bracket 45 at a vehicle body front side (vehicle body rear side) with respect to the swing shaft 45 a. The pressing portion 45b is disposed on the vehicle width direction outer side and the vehicle body front side of the interference portion 45 e.

Fig. 21 is a sectional view taken along line XXI-XXI of fig. 4. In this figure, battery B is omitted for the sake of explanation. The swing shaft 45a of the push bracket 45 is disposed to be slidable in the vertical direction with respect to the operating lever 60 so as to be directed in the vehicle width direction. This facilitates the swinging of the pressing bracket 45 in conjunction with the sliding operation of the operating lever 60. Further, since the two corners 61a on the upper end side of the grip portion 61 are formed by curved surfaces, the battery B can be protected even if the side surface of the battery B abuts against the operation lever 60 when the battery B is inserted into the battery case 40.

Fig. 22 is a sectional view taken along line XXII-XXII of fig. 21. Fig. 23 is a sectional view taken along line XXIII-XXIII in fig. 21. The pressing bracket 45 is provided with a contact portion 49 that comes into contact with the operating lever 60 when the operating lever 60 is pressed down. The contact portion 49 includes a first contact portion 49a (see fig. 22) which is not located on the radially outer side of the rocking shaft 45a, and a second contact portion 49b (see fig. 23) which is disposed close to the radially outer side of the rocking shaft 45 a.

The area of contact between the first contact portion 49a provided near the center in the vehicle width direction and the operating lever 60 is set larger than the area of contact between the second contact portion 49b provided near the outer side in the vehicle width direction and the operating lever 60. Thus, the holding force by the pressing bracket 45 can be increased by increasing the contact area with the operating lever 60 in the region not overlapping with the swing shaft 45a of the pressing bracket 45 in the axial direction.

According to the above-described configuration of the contact portion 49, the battery B is accommodated in the battery case 40, and the operation lever 60 is pressed down, whereby the pressing bracket 45 presses the upper surface 102 of the battery B, and the operation lever 60 is brought into contact with the pressing bracket 45. That is, the operation lever 60 restricts the swing operation of the pressing bracket 45, and thus, even when the battery B passes over a large slope, the battery B is prevented from moving upward in the vehicle body, and good electrical connection can be maintained.

Fig. 24 is a front view showing the relationship between the battery B and the operating lever 60 in the middle of storage. The battery B is formed in a substantially rectangular parallelepiped shape that is long in the vertical direction of the vehicle body. When battery B is pulled upward with terminal holder 74 set at retracted position D, inclined side surface 103a provided at a position close to the upper side of battery B is pushed open and swings in a direction away from battery B. That is, by pulling up battery B, operation lever 60 is automatically swung to enable battery B to be removed, and thus the operation of removing battery B becomes easy. The inclination of the center line C of the operating lever 60 is set to such a degree that the inclined side surface 103a can automatically swing to the opposite side along the shape of the coupling portion 69 of the operating lever 60 even when the battery B on the inclined side of the operating lever 60 is pulled out. Further, an upper corner portion of the grip portion 61 of the operating lever 60 functions as a guide member for abutting against the vehicle width direction inner side surface of the battery B and accommodating the battery B at a predetermined position when the battery B is inserted.

Fig. 25 is a perspective view of a seat pan 80 constituting a bottom of the seat 23 viewed from a lower side of the vehicle body. Fig. 26 is a sectional view taken along line XXVI-XXVI in fig. 4. In fig. 26, the seat 23 is also shown, as well as a seat pan 80. A fixing member 82 for fixing to the hinge mechanism 44 is provided at the front end of the seat pan 80, and a pair of left and right anti-vibration rubbers 84a that absorb shock and vibration when the seat 23 is closed and a hook 83 that engages with the seat latch mechanism 110 are provided at the rear end of the seat pan 80. Further, bosses 84 are provided at the front and rear of the center in the vehicle width direction of the seat pan 80 so as to abut on the upper surface of the operating lever 60. The boss 84 can be formed of a hard synthetic resin or the like. A recess 85 that avoids interference with the pressing portion 64 of the operating lever 60 is formed around the boss 84 on the vehicle body front side.

The boss 84 has a function of pressing the operation lever 60 when the seat 23 is closed in a state where the operation lever 60 is lifted upward from the predetermined lowest position, but is set so as not to abut against the operation lever 60 in a state where the operation lever 60 is pressed down to the predetermined lowest position. Thus, when the operating lever 60 is not sufficiently depressed when the seat 23 is closed, the boss 84 is set to abut against the operating lever 60 and be pushed into the minimum position where the battery-side terminal 75 and the case-side terminal 90 are electrically connected, and when the operating lever 60 is depressed to the predetermined minimum position, the boss 84 does not abut against the operating lever 60, thereby preventing a load from being further applied to the operating lever 60 that is sufficiently depressed.

Fig. 27 is a structural explanatory diagram of the battery-side terminal 75. Fig. 28 is a perspective view of the case-side terminal 90. The battery side terminal 75 is embedded at a position on the lower surface 107 of the battery B near the outer side in the vehicle width direction. The battery-side terminal 75 is formed with a slit 76 into which seven terminal plates 94 of the case-side terminal 90 are inserted, and an engagement hole 77 into which a positioning pin 93 supported by a support portion 93a on the outer side of the terminal plate 94 is inserted.

A through hole 92 is formed in the base plate 91 of the terminal block 94 and the positioning pin 93 for supporting the case-side terminal 90, and the through hole 92 passes through a support shaft for allowing the case-side terminal 90 to slide with respect to the terminal holder 74 (see fig. 29 and 30). A protection plate 94a for protecting the terminal plate 94 is erected on a side of the terminal plate 94, and a harness holder 95 for supporting a harness for supplying electric power is provided on a lower surface of the bottom plate 91.

Fig. 29 and 30 are explanatory views of the structure of the preload mechanism for pressing the case-side terminal 90 against the battery-side terminal 75. Fig. 29 shows a state in which the operating lever 60 is pushed down to a position at which the case-side terminal 90 engages with the battery-side terminal 75, and fig. 30 shows a state in which the operating lever 60 is further pushed down to a predetermined lowest position to apply a preload. Fig. 29 and 30 (b) are enlarged cross-sectional views of the dotted circle portion of (a).

The case-side terminal 90 is supported slidably in the vertical direction with respect to the terminal holder 74 by a cylindrical support shaft 98 inserted through a through hole 74a formed in the terminal holder 74. The coil spring 97 around the support shaft 98 is configured to generate an elastic force in a direction of separating the terminal holder 74 from the case-side terminal 90. The longest distance between the terminal holder 74 and the housing-side terminal 90 is limited by the snap ring 98a, and the shortest distance between the terminal holder 74 and the housing-side terminal 90 is limited by the cup-shaped member 96 disposed on the lower surface of the bottom plate 91 and covering the coil spring 97.

In the present embodiment, when the battery B is housed in the battery case 40 and the operation lever 60 is pressed down, the electrical connection of the case-side terminal 90 and the battery-side terminal 75 is completed immediately before the lowermost position of the operation lever 60 is reached, and the coil spring 97 is further pressed down to the lowermost position, so that the preload is generated by contraction. In this case as well, a gap 99 between the cup-shaped member 96 and the terminal holder 74 can be ensured.

As described above, according to the preload mechanism of the present embodiment, the spring 97 that biases the case-side terminal 90 in the direction of pressing the case-side terminal 90 against the case-side terminal 90 is disposed between the case-side terminal 90 and the terminal holder 74, and thus the pressing force that presses the case-side terminal 90 against the battery-side terminal 75 can be generated in the state where the case-side terminal 90 is moved to the connection position. Thus, even when the battery B moves upward in the vehicle body, for example, when the battery B passes over a large slope, the case-side terminals 90 can be kept electrically connected following the movement of the battery B.

Further, since the single operation lever 60 that restricts the vertical movement of the battery B by being pressed downward in a state where the battery B is housed in the battery case 40 and the link mechanism L that couples the operation lever 60 and the terminal holder 74 are provided, the vertical movement of the battery B can be restricted by the single operation lever 60, and the attachment/detachment work of the battery B becomes easy. Even when the operation of the operating lever 60 is lost due to the link mechanism L including a plurality of rocking shafts, the coil spring 97 can absorb the movement after the case-side terminal 90 comes into contact with the battery-side terminal 75, and the preload can be effectively applied to both terminals.

Further, by providing a pair of support shafts 98 of the winding coil spring 97 with the case-side terminal 90 interposed therebetween, the sliding mechanism of the terminal holder 74 is provided on both sides of the case-side terminal 90, and thus, the case-side terminal 90 can be prevented from being inclined, and a smooth sliding operation can be performed. This can maintain good electrical connection between the case-side terminal 90 and the battery-side terminal 75.

The shape and structure of the battery, the number and mounting position of the battery, the shape and structure of the battery case and the operation lever, the shape and structure of the pressing holder and the terminal holder, the shape and structure of the link mechanism and the preload mechanism, and the like are not limited to the above-described embodiments, and various modifications are possible. The battery attachment/detachment structure for a saddle-ride type vehicle according to the present invention can be applied to a saddle-ride type three-wheeled electric vehicle, a four-wheeled electric vehicle, and the like.
