The pushing part 111 is a rectangular plate with a through hole 114 formed in the center, which is suitable for exposing the charging base 31 in the battery slot. The linkage part 112 is a long piece and is self-propelled. The upper edge of the resisting portion 111 extends in the opposite direction to the battery box 30 . The linkage portion 112 and the pushing portion 111 are approximately perpendicular to each other and connected. The portion 113 is a long piece and extends from one side of the pushing portion 111 in the opposite direction to the battery box 30 . The connecting portion 113 and the pushing portion 111 are approximately perpendicular to each other. From the above, it can be seen that the linkage portion 112 and The connecting portions 113 all extend from the peripheral position (upper edge, one side) of the pushing portion 111 in the direction opposite to the battery box 30 , which means that the outer position of the pushing plate 11 opposite to the rear end of the battery box 30 will be freed, and can It is convenient to inspect the mechanism at the rear end of the battery box 30 .

The driving device 12 includes a base 121 and a telescopic rod 122. The telescopic rod 122 is telescopically disposed on the base 121 and can move toward or away from the base 121. The base 121 is disposed on the outer wall of the battery box 30. And adjacent to the rear end position, one end of the telescopic rod 122 is fixed on the connecting portion 113, so that the push plate 11 can be linearly moved in the front-rear direction toward the front end or the rear end by the driving device 12 relative to the battery box 30. In this embodiment, the driving device 12 is composed of a screw electric cylinder.

One end of the linkage block 13 has an inclined surface 131. The linkage block 13 is fixed on the linkage portion 112 of the push plate 11 and the inclined surface 131 faces the front end direction.

Please refer to FIGS. 1 to 3 . The buckle mechanism 20 includes a fastener 21 , a buckle body 22 , a bracket 23 , a roller 24 , a front shaft 25 , a rear shaft 26 and an elastic member 27 , the fastener 21 protrudes from one end of the buckle body 22 and corresponds to the through groove 31 at the rear end of the battery box 30, so that it can be fastened to the slot 41 at the corresponding position of the battery 40 through the through groove 31. The front end of the fastener 21 A guide surface 211 is formed. The guide surface 211 is a surface extending downward and rearward. The other end of the buckle body 22 is pivoted on the bracket 23 through the rear shaft 26. The elastic member 27 is a torsion spring, which is sleeved The rear shaft 26 and the two ends of the elastic member 27 respectively abut against the bracket 23 and the opposite inner surfaces of the buckle body 22 , and the roller 24 is rotatably disposed on the buckle body 22 through the front shaft 25 and located on the buckle 21 The bracket 23 is fixed on the outer wall of the battery box 30 adjacent to the rear end between the battery box 30 and the rear axle 26 . The position of the roller 24 corresponds to the slope 131 of the linkage block 13 and the moving path position of the linkage block 13 .

When using the present invention, please refer to Figures 1 and 4, taking a battery 40 as an example. One side of the battery 40 is concavely formed with a slot 41. The slot 41 is adjacent to the bottom surface of the battery 40. The battery A rounded corner 42 is formed between the side and the bottom surface of 40. When the battery exchange station is in the standby state, all components in the buckle mechanism 20 except the bracket 23 are in a movable state.

Please refer to FIG. 4 . When the battery 40 enters the front opening of the battery box 30 and moves toward the rear end, the rounded corner 42 of the battery 40 contacts the guide surface 211 of the buckle 21 , and the buckle body 22 rears the shaft 26 In order to rotate the center, the end with the fastener 21 gradually lifts upward and pivots. At this time, the elastic member 27 is compressed. Please refer to Figure 5. When the fastener 21 gradually moves away from the rounded corner 42 of the battery 40 and is located in the slot of the battery 40. At 41 , the elastic force released by the elastic member 27 causes the end of the buckle body 22 with the buckle 21 to pivot downward, and the buckle 21 enters the slot 41 to lock the battery 40 .

When the battery 40 in the battery box 30 is in a charging state, all components of the buckle mechanism 20 are in an immovable state. If a user intends to pull the battery 40 out of the battery box 30 at this time, the locking slot 41 of the battery 40 will The inner wall surface will contact the fastener 21 to prevent the battery 40 from moving outward to achieve the locking effect of the battery 40 .

Please refer to FIG. 6 . When the battery 40 in the battery box 30 is fully charged, the telescopic rod 122 is driven by the driving member of the driving device 12 to operate, and the push plate 11 connected to the telescopic rod 122 also moves toward the front end. , at this time, the linkage block 13 provided on the push plate 11 will contact the roller 24 of the buckle mechanism 20 with its inclined surface 131, so that the rear shaft 26 of the buckle mechanism 20 will be the center of rotation, causing the end with the fastener 21 to lift upward, and the buckle mechanism 20 will The member 21 moves upward simultaneously to disengage from the slot 41 of the battery 40. After the fastener 21 disengages from the slot 41, the pushing portion 111 of the push plate 11 then abuts against the bottom surface of the battery 40 and pushes the battery 40 toward the front end of the battery box 30. Move the opening direction to protrude from the front opening.

During the aforementioned process, since the entire mechanism of the present invention is in a linked state and is closely adjacent to the rear end of the battery box 30, the connecting portion of the pushing plate of the pushing mechanism for connecting with the driving device and the linking portion where the linking block is provided are both It extends in the opposite direction to the outside of the rear end of the battery box and is located on the side and upper edge of its pushing part. Therefore, the space at the rear end of the battery box will not be obstructed by the installation of the pushing mechanism and the buckling mechanism. , and the occupied volume is smaller than the existing technology and is easy to maintain and repair. In addition to reaching In addition to cost reduction, the number of battery boxes 30 can be increased per unit space to improve space utilization efficiency.
