The high voltage terminal pins 140 and the signal terminal pins 141 are arranged in a line in the lateral direction of the vehicle. The high voltage terminal pins 140 are respectively disposed outside the plurality of signal terminal pins 141 in the vehicle width direction. The heights of the upper end portions of the high voltage terminal pins 140 disposed on both sides in the vehicle width direction are higher than the height of the upper end portion of the signal terminal pin 141. Therefore, when the case side connection terminal 43 is displaced integrally with the terminal support block 139 from the retracted position P2 to the connection position P1, the high voltage terminal pin 140 is a terminal portion on the battery 62A (62B) side prior to the signal terminal pin 141. Contact 41

Also, at the lower end of the terminal support block 139, a cable connection wall 143 for connecting the power cable 142 (electric wire) to the high voltage terminal pin 140, and a signal for connecting the signal wire 144 (electric wire) to the signal terminal pin 141 A wire connection 145 is provided. The cable connection wall 143 is disposed on the outer side in the vehicle width direction of the signal line connection portion 145. A bolt 146 for connecting the metal lead of the power cable 142 to the high voltage terminal pin 140 is fastened to the cable connection wall 143 from the outside in the vehicle width direction. The bolt 146 constitutes a fixing means for electrically connecting the power cable 142 to the high voltage terminal pin 140 and also for firmly connecting physically and physically.

A cable support bracket 201 is attached to the terminal support block 139 as shown in FIG. The cable support bracket 201 holds the power cable 142 and the signal line 144 bundled by the clamp device 202. The cable support bracket 201 is supported by a stay (not shown) protruding downward from a lower end near one side of the terminal support block 139 in the vehicle width direction. The cable support bracket 201 extends downward from the terminal support block 139 side and then curves in a substantially J shape in the vehicle width direction along the drawing direction of the power cable 142 and the signal line 144. The clamp device 202 is supported on the distal end side of the curved portion of the cable support bracket 201. The lower end of the cable support bracket 201 and the clamp device 202 are located below the cable connection wall 143 of the terminal support block 139 and the signal line connection portion 145.

A pair of guide projections 147, which are case-side guide portions, project upward at a position outside the case-side connection terminal 43 of the terminal support block 139 in the vehicle width direction. The entire guide projection 147 is formed in a substantially cylindrical shape, and a spherical curved surface or a tapered tapered surface is provided at the tip thereof. The left and right guide protrusions 147 project upward from the upper end portions of the high voltage terminal pin 140 of the case-side connection terminal 43 and the signal terminal pin 141.

On the other hand, on the lower surface of the battery 62A (62B) housed in the resin case portion 132F (132R), a pair of guide holes 148 capable of receiving the left and right guide protrusions 147 on the terminal support block 139 side are provided. The guide hole 148 constitutes a battery side guide portion. Here, when the case-side connection terminal 43 ascends toward the connection position P1 (see FIGS. 17, 25 and 26) with the battery 62A (62B) housed in the resin case portion 132F (132R), The guide protrusion 147 is inserted into the guide hole 148 before the case-side connection terminal 43 contacts and connects with the terminal portion 41 of the battery 62A (62B). In the case of the present embodiment, when the case-side connection terminal 43 is at the retracted position P2, the guide protrusion 147 is separated by the distance L1 between the guide protrusion 147 and the contact portion of the guide hole 148 with the case-side connection terminal 43 and the battery 62A. It is set to be shorter than the separation distance L2 of the terminal portion 41 of (62B). As shown in FIG. 17, the upper end 147 e of the guide protrusion 147 which is the guide end in the battery direction of the guide protrusion 147 is higher than the upper end 140 e of the high voltage terminal pin 140 which is the terminal end of the case connection terminal 43 in the battery direction. It is formed on the side (battery side).

The terminal displacement mechanism 45 includes a terminal holding member 149 that holds the case-side connection terminal 43 via the terminal support block 139. The terminal holding member 149 is made of a metal plate material, and a pair of left and right portions bent and extended upward from both end portions in the vehicle width direction of the base wall 149a extending in the vehicle width direction and the base wall 149a. And a connecting wall 149b. An elongated through hole 150 is formed in a central region in the vehicle width direction of the base wall 149a. The terminal support block 139 is held on the lower surface side of the base wall 149 a via the connection pin 151 and the spring unit 152. A part of the terminal support block 139 held by the base wall 149 a and the case-side connection terminal 43 protrude upward through the insertion hole 150 to the upper side of the base wall 149 a.

Insertion holes 153 into which the connection pins 151 are inserted are formed at both edges of the terminal support block 139 in the vehicle width direction. The inner diameter of the insertion hole 153 is formed larger than the outer diameter of the connection pin 151. The terminal support block 139 is displaceable in a substantially horizontal direction (direction intersecting with the connection direction to the terminal portion 41) in the range of the gap between the insertion hole 153 and the connection pin 151. Therefore, the case-side connection terminal 43 supported by the terminal support block 139 is held by the terminal holding member 149 so as to be relatively displaceable in the direction intersecting the connection direction with respect to the terminal portion 41.

The connection pin 151 is slidably inserted into a support hole 198 provided in the base wall 149 a of the terminal holding member 149. A retaining flange 151 a is integrally provided at the upper end portion of the connection pin 151. The connecting pin 151 is prevented from coming off with respect to the base wall 149a by the abutment of the retaining flange 151a with the upper surface of the base wall 149a.

The spring unit 152 has a cylindrical metal unit case 154 with a bottom, a disc-like stopper plate 155 that can abut the opening end of the unit case 154, and an inner bottom surface of the unit case 154 and the stopper plate 155. And a coil spring 156 which is an elastic member interposed therebetween. The spring unit 152 is disposed below the base wall 149a in a state where the outer bottom surface of the unit case 154 is in contact with the lower surface of the base wall 149a. The connection pin 151 penetrates the bottom wall of the unit case 154 and is coupled to the stopper plate 155 below the unit case 154. Further, the coil spring 156 is disposed in the circumferential area of the connection pin 151.

The case-side connection terminal 43 and the terminal support block 139 are suspended and supported by the terminal holding member 149 via the spring unit 152 and the connection pin 151. The unit case 154 and the stopper plate 155 are maintained in the separated state until a predetermined or more pressing load is input to the case side connection terminal 43 from the upper side. In this state, when a predetermined pressure load is input to the case-side connection terminal 43, the terminal support block 139 is displaced downward relative to the terminal holding member 149 while the coil spring 156 is compressed and displaced. Thus, when the terminal support block 139 is displaced relative to the terminal holding member 149 by a predetermined amount or more, the stopper plate 155 abuts against the unit case 154, whereby the terminal support block 139 (case side connection terminal 43) for the terminal holding member 149 Relative displacement is regulated (see FIG. 26).

The left and right connecting walls 149b of the terminal holding member 149 are rotatably held at the lower end of the metal link plate 157 in the lower region outside the side of the resin case portion 132F (132R). The link plate 157 is a plate member elongated in one direction extending substantially in the vertical direction. The upper end portions of the left and right link plates 157 are rotatably connected to the tips of left and right lever pieces 44 a of the operation lever 44 which is an operation member. A middle region in the extending direction of the left and right lever pieces 44 a is pivotally supported by the left and right support stays 135 attached to the battery support frame 110. The left and right link plates 157 are pulled upward by turning the operation lever 44 in one direction (clockwise direction in FIGS. 14 and 16), whereby the left and right sides of the terminal holding member 149 are moved. Each connecting wall 149b is displaced upward. At this time, the case-side connection terminal 43 held by the terminal holding member 149 is displaced from the retracted position P2 to the connection position P1.
In addition, the code | symbol 197 in FIG. 14, FIG. 16 is a reinforcement frame which is attached to lower end vicinity of the support stay 135 on either side, and reinforces the circumferential area of resin case part 132F (132R).

The lower ends of the left and right link plates 157 and the left and right connection walls 149b of the terminal holding member 149 are linked with each other by inserting a pivot pin 158 into the long hole 159, as shown in FIG. The pivot pin 158 is supported by the left and right connection walls 149 b, and the long holes 159 are formed in the link plate 157. Therefore, when the link plate 157 is pulled upward by the operation of the operation lever 44, as shown in (I) and (II) of FIG. 17B, the pivot pin is moved by a predetermined stroke of the link plate 157. 158 floats in the long hole 159. As a result, with respect to the start of the operation of the operation lever 44, the timing at which the terminal holding member 149 starts the upward displacement is delayed.
FIG. 17B is a diagram showing an operation state of a portion E of FIG. 17A.

The lock mechanism 133 for fixing the battery 62A (62B) to the battery case 42 includes a movable block 160. The movable block 160 is rotatably (displaceably) attached to the upper end portions of the left and right support stays 135 of the battery case 42. When the operating lever 44 pivots from the initial position to the predetermined position range, the movable block 160 pivots in the upper surface direction of the battery case 42 by receiving an operating force from the operating lever 44. The movable block 160 is pressed against the upper surface of the battery 62A (62B), and regulates displacement of the battery 62A (62B) in the removal direction.

FIG. 19 is a view of the operation lever 44 and the movable block 160 as viewed from the upper right front of the support stay 135 on the left side.
The operation lever 44 is rotatably supported by the support stay 135 about the first rotation shaft 162. The first pivoting shaft 162 is a shaft pivotally supported at a front center portion of the support stay 135 substantially in the vertical direction, and is disposed along the vehicle width direction of the vehicle. In some of the drawings, only the axial center o1 of the first rotation shaft 162 is shown.

The movable block 160 of the lock mechanism 133 is rotatably supported by the support stay 135 about a second rotation shaft 163 orthogonal to the first rotation shaft 162. The second pivot shaft 163 is a shaft pivotally supported by the upper end portion of the support stay 135, and is disposed along the longitudinal direction of the vehicle.

In the case of the present embodiment, the first pivoting shaft 162 is arranged such that the axis o1 of the first pivoting shaft 162 overlaps the battery 62A (62B) accommodated in the resin case portion 132F (132R) (see FIG. 20 (c), FIG. 22 (c), FIG. 24 (c) etc.). In addition, the second pivoting shaft 163 is disposed so that the axis o2 of the second pivoting shaft 163 is located outside the battery 62A (62B) housed in the resin case portion 132F (132R) (see FIG. 20 (c), FIG. 22 (c), FIG. 24 (c) etc.).

The operation lever 44 has an operation piece 44b extending along the vehicle width direction, and left and right lever pieces 44a bent and extended in substantially orthogonal directions from both end portions of the operation piece 44b. An intermediate region in the extending direction of the left and right lever pieces 44 a is supported by the first and second support stays 135 by the first pivot shaft 162. The left and right lever pieces 44a are formed to be bent in a substantially L shape in a side view (a substantially L shape in which the tip portion protrudes forward). Hereinafter, the side of the operation piece 44b is referred to as a first extending part 44a-1 with the bent portion of the lever piece 44a interposed therebetween, and the side opposite to the operation piece 44b is referred to as a second extending segment 44a-2 with the bent portion interposed therebetween. I assume. The left and right lever pieces 44a are supported by the support stay 135 at a substantially intermediate position in the extension direction of the second extending piece 44a-2 via the first pivot shaft 162. The upper end portion of the link plate 157 is rotatably connected to the tip end portion of the second extending piece 44a-2 via a connection pin 164.

Here, as shown in FIG. 19, the movable block 160 of the lock mechanism 133 has a pivot 160a, a displacement restricting wall 160b (battery restricting portion), an elastic block 160c (battery restricting portion), and a holding force receiving wall 160 d (holding force receiving portion) and a cam wall 160 e. The pivot portion 160 a is rotatably supported by the second pivot shaft 163. The displacement restricting wall 160b is connected to the pivot portion 160a, and when it is displaced to the inner region of the resin case portion 132F (132R), the displacement of the battery 62A (62B) in the floating direction can be restricted. The elastic block 160c is attached to one surface of the displacement regulating wall 160b, and directly abuts on the upper surface of the battery 62A when the displacement regulating wall 160b regulates the displacement of the battery 62A (62B) in the floating direction. At this time, the elastic block 160c is elastically deformed to cause the elastic force to act on the upper surface of the battery 62A.

The displacement restricting wall 160b of the movable block 160 and the elastic block 160c (battery restricting portion) are outside the batteries 62A and 62B in the battery unfixed state as viewed from the insertion direction of the batteries 62A and 62B with respect to the resin case portion 132F (132R). It is configured to be positioned (see FIG. 20 (c)) and to overlap with the batteries 62A and 62B in the battery fixed state (see FIGS. 22 (c) and 24 (c)).

The holding force receiving wall 160d is provided continuously with the pivot portion 160a, and extends around the second rotation shaft 163 in a direction substantially perpendicular to the displacement control wall 160b. The holding force receiving wall 160d receives a holding load from the lever piece 44a of the operation lever 44, and maintains the state in which the displacement regulating wall 160b and the elastic block 160c regulate the displacement of the battery 62A (62B) in the floating direction. The cam wall 160e is a wall connecting the displacement restricting wall 160b and the holding force receiving wall 160d on the front side, and the back surface 160d-1 (holding force receiving surface) of the holding force receiving wall 160d from the displacement restricting wall 160b side It has a cam surface 160e-1 smoothly continuous in the direction.

In the case of the present embodiment, the holding force receiving wall 160 d (holding force receiving portion) is configured to overlap the lever piece 44 a of the operation lever 44 in the battery fixed state in a direction view along the first pivot shaft 162 (See Figure 19).

The movable block 160 of the lock mechanism 133 has a lock release position in which the displacement restricting wall 160b and the elastic block 160c jump upward in response to the turning operation of the operation lever 44, and the displacement restricting wall 160b and the elastic block 160c are resin cases. It can be pivoted between the lock position in which the part 132F (132R) is inclined by approximately 90 degrees inward. The lock mechanism 133 is in the battery non-fixing state when the displacement restricting wall 160b and the elastic block 160c are in the unlocking position, and is in the battery fixing state when the displacement restricting wall 160b and the elastic block 160c are in the locking position. In addition, each movable block 160 is always urged | biased in the springing direction by the spring which is not shown in figure.

When the battery is not fixed, the operation lever 44 is turned forward to the maximum, and at this time, the operation piece 44b of the operation lever 44 is displaced forward of the insertion and removal opening 136 (inner wall) of the resin case portion 132F (132R). There is. The position of the operation lever 44 at this time is referred to as an initial position. Further, in the battery fixed state, the operation lever 44 is raised to the rear upper side, and at this time, the operation piece 44b of the operation lever 44 is displaced to the upper position of the insertion / removal opening 136 of the resin case portion 132F (132R).

Further, in the first extending portion 44a-1 of the lever piece 44a of the operation lever 44, a cam protrusion 165 which bulges rearward is formed. The cam projection 165 abuts on the cam surface 160e-1 of the movable block 160 in the flipped up state and is in sliding contact with the cam surface 160e-1 when the operation lever 44 is raised from the initial position to the upper rear side. The movable block 160 is pressed in the rotational direction. The movable block 160 is thereby turned from the unlocked position toward the locked position. Thus, when the operation of causing the operation lever 44 progresses and the contact portion of the cam projection 165 reaches the end position of the cam surface 160e-1, the inner side surface (the surface facing inward in the vehicle width direction) of the lever piece 44a is the movable block 160 The holding force receiving wall 160d abuts on the back surface 160d-1. This state continues until the operation lever 44 reaches the maximum pull-up operation position.

The lock mechanism 133 and the terminal displacement mechanism 45 are operated by the common operation lever 44. The operating states of the lock mechanism 133 and the terminal displacement mechanism 45 are determined by the rotational operation position of the operation lever 44. In the terminal displacement mechanism 45 and the lock mechanism 133, the lock mechanism 133 fixes the battery 62A (62B) by the operation of the operation lever 44, and the terminal displacement mechanism 45 displaces the case side connection terminal 43 to the connection position P1 in that state. And so on.

Next, referring to FIGS. 20 to 26, after battery 62A (62B) is inserted into resin case portion 132F (132R), battery 62A (62B) is fixed to resin case portion 132F (132R), and A series of operations for connecting the case side connection terminal 43 to the terminal portion 41 of the battery 62A (62B) will be described.
In the state shown in FIG. 20, the operating lever 44 is in the initial position at which the operating lever 44 is maximally tilted forward. At this time, the tip of the lever piece 44a of the operation lever 44 is positioned at the lowermost position, and the link plate 157 and the terminal holding member 149 of the terminal displacement mechanism 45 are also displaced to the lowermost position. The battery 62A (62B) is inserted in the resin case portion 132F (132R) in this state. At this time, the case side connection terminal 43 is located at the retracted position P2 as shown in FIG. In addition, the movable block 160 of the lock mechanism 133 is positioned at the lock release position that has jumped upward.

When the operation lever 44 is pulled and operated from this state, as shown in FIG. 21, the cam projection 165 of the operation lever 44 abuts on the cam surface 160e-1 of the movable block 160 and is in sliding contact with the cam surface 160e-1. At the same time, the movable block 160 is pivoted in the lock position direction.
At the beginning of the operation of the operation lever 44, the link plate 157 is pulled up by the lever piece 44a, but there is play due to the long hole 159 between the link plate 157 and the terminal holding member 149 as described above. The start of the upward displacement of the holding member 149 is delayed.

When the raising operation of the operation lever 44 proceeds, as shown in FIG. 22, the rotation of the movable block 160 proceeds, and the elastic block 160c of the movable block 160 comes in contact with the upper surface of the battery 62A. At this time, the terminal holding member 149 of the terminal displacement mechanism 45 is displaced upward by pulling up by the operation lever 44 via the link plate 157. Further, at this time, as shown in FIG. 23, the guide projection 147 of the terminal support block 139 is fitted into the guide hole 148 on the lower surface side of the battery 62A (62B), whereby the terminal support block 139 and the case side connection terminal 43 are provided. The position in the direction intersecting with the terminal connection direction is finely adjusted.

When the raising operation of the operation lever 44 further progresses, as shown in FIG. 24, the lever piece 44a of the operation lever 44 comes in contact with the back surface side of the holding force receiving wall 160d of the movable block 160. Thereby, the displacement restricting wall 160b of the movable block 160 is pivoted to a predetermined displacement restricting position, and the displacement of the battery 62A (62B) in the floating direction is restricted via the elastic block 160c. At this time, as shown in FIG. 25, the terminal holding member 149 of the terminal displacement mechanism 45 is further raised by pulling up by the operation lever 44 via the link plate 157, and the case side connection terminal 43 is displaced to the connection position P1. Thus, the case side connection terminal 43 is fitted and connected to the terminal portion 41 of the battery 62A (62B).

When the operation lever 44 is further pulled from the state shown in FIG. 24 and operated in the direction for a predetermined amount, in the terminal displacement mechanism 45, the terminal holding member 149 is further displaced upward as shown in FIG. At this time, the coil spring 156 of the spring unit 152 is compressed, and the case side connection terminal 43 is pressed against the terminal portion 41 of the battery 62A (62B) with a predetermined load. Thereby, the lock of the battery 62A (62B) by the lock mechanism 133 and the terminal connection by the terminal displacement mechanism 45 are completed.
In the case of the present embodiment, when the operation lever 44 is operated to the operation completion position, a click sound such as a tapping sound is generated at an arbitrary position in the battery storage device 64 to complete the operation to the operator A mechanism is provided to

It is provided to enter the space on the front side of the Further, as shown in FIG. 27, the pair of projections 171A and 171B abut on the upper surface of the operation piece 44b of the operation lever 44 when the front and rear operation levers 44 of the battery storage device 64 are in a state before the operation is completed It is set. Therefore, when one of the control levers 44 is not completely operated to the operation completion position, the blocking of the seat 8 is inhibited by the projections 117A and 117B. Therefore, the operator can be notified that the control lever 44 has not reached the operation complete position.

Depending on the position of the operating lever 44, the operating lever 44 can be pushed to the operation complete position by bringing the projections 171A and 171B into contact with the upper surface of the operating piece 44b of the operating lever 44 when the seat 8 is closed. .
