The frame 16 is a frame-like structure having a support surface 160 that supports the battery pack assembly 2. The fixed plate 22 has a plurality of first pulleys 23 mounted on the bottom side thereof, and the first pulleys 23 are supported on the support surface 160. When assembled, the battery pack assembly 2 is moved forward from the rear side, and the first pulley 23 rolls on the support surface 160 of the frame 16. Compared with the surface-to-surface sliding friction mode in the prior art, the friction force in the pulley rolling mode is smaller, and an operator can mount or dismount the battery pack assembly 2 more labor-saving.
The battery pack assembly 2 is substantially rectangular in shape, wherein the front-rear direction is the longitudinal direction thereof, and the first pulleys 23 are distributed dispersedly along the longitudinal direction. In the present embodiment, the first pulleys 23 include six, four of which are located at four corners of the battery pack assembly 2 and the other two of which are located on opposite sides of the middle portion of the battery pack assembly 2 in the width direction. The six first pulleys 23 are divided into two rows, and the three first pulleys 23 in each row are uniformly distributed along the long edge of the battery pack assembly 2, so that the battery pack assembly 2 is supported together, and the smooth movement of the battery pack assembly 2 is ensured. The specific number of the first pulleys 23 is not particularly limited, and the present embodiment is only to illustrate six first pulleys 23, preferably three or more, and preferably uniformly distributed, so as to uniformly support the battery pack assembly 2 during the movement.

The battery pack assembly 2 further comprises a plurality of supporting legs 24, a second pulley 25 is installed at the tail end, also called the bottom end, of each supporting leg 24, the top end of each supporting leg 24 is pivotally connected with the fixing plate 22, so that the supporting legs 24 have a foldable function, and the supporting legs 24 are used for supporting the battery pack assembly 2 on the ground when the battery pack assembly is detached and installed.
In the present embodiment, the battery pack assembly 2 includes four support legs 24, two on the front side and two on the rear side; the connecting points of the top of each supporting foot 24 and the fixing plate 22 are respectively arranged at the four corners of the fixing plate 22. In fact, the specific number of support feet 24 is not limited, but may alternatively be three, for example two behind and one in front; or more than four support legs 24 may be provided as long as the battery pack assembly 2 can be stably supported.
The support feet 24 are horizontally disposed on the bottom side of the fixed plate 22 when folded. The length of the support feet 24 is designed to depend on the height of the frame 16 from the ground such that the absolute height of the battery pack assembly 2 remains substantially constant during removal or installation. With the battery pack assembly 2 partially removed from the frame 16, the second pulleys 25 of the open support feet 24 can be supported on the ground, supporting the battery pack assembly 2 in cooperation with the frame 16.
In the present embodiment, the length of the support foot 24 is adjustable, the support foot 24 includes an upper section 241 and a lower section 242, the upper section 241 is connected to the fixing plate 22, and the lower section 242 has a hollow structure. When the foldable support leg is folded, the lower section 242 is sleeved outside the upper section 241, so that the overall occupied space of the support leg 24 is reduced, when the foldable support leg is used, the lower section 242 is pulled downwards, so that the lower section 242 moves downwards, and the lower section 242 after moving downwards is positioned to the upper section 241 through the concave-convex structure, so that the overall length of the support leg 24 is extended.
Six first mounting brackets 221 and four second mounting brackets 222 are disposed on the fixing plate 22, the first mounting brackets 221 are of an inverted U-shaped structure, and the first pulleys 23 are pivotally connected to openings of the first mounting brackets 221. The second mounting bracket 222 also has an opening, and the top of the upper section 241 of the support foot 24 is pivotally connected to the opening of the second mounting bracket 222. The first mounting brackets 221 and the second mounting brackets 222 may be fixed to the bottom side of the fixing plate 22 by welding, and are arranged in two rows, each row includes three first mounting brackets 221 and two second mounting brackets 222, and the two second mounting brackets 222 are spaced between two adjacent first mounting brackets 221.
The second mounting rack 222 can also limit the supporting legs 24 from over-rotating, and specifically, the second mounting rack 222 corresponding to the supporting leg 24 located at the front side is provided with a blocking wall (not shown) for preventing the supporting leg 24 located in the vertical direction from continuing to rotate forward; the second mounting bracket 222 corresponding to the supporting foot 24 on the rear side is provided with a blocking wall 223 preventing the supporting foot 24 in the vertical direction from continuing to rotate backwards. The support foot 24 terminates in a U-shaped opening 243, and the second pulley 25 is pivotally connected within the U-shaped opening 243.
The battery pack assembly 2 is provided with a handle 224 at the rear side of the fixing plate 22, and when the operator removes the battery pack assembly 2, the stopper (not shown) is removed by opening the rear cover 17, and then the operator pulls the battery pack assembly 2 backward by holding the handle 224. Referring to fig. 6, when the two supporting feet 24 on the rear side are out of the constraint of the frame 16, they can be opened manually or automatically, and the second pulley 25 can contact the ground. At this time, the center of gravity of the battery pack assembly 2 is still on the frame 16, and the frame 16 can support the battery pack assembly 2 alone, so that the battery pack assembly 2 does not fall off until the two support legs 24 on the rear side are opened. A line connecting the center points of the two long sides of the battery pack assembly 2 is defined as a center line, and the front ends of the folded rear support legs 24 are positioned on the rear side of the center line during design. It is ensured that the rear support feet 24 are already able to rest on the ground before half the length of the battery pack assembly 2 is removed from the frame 16.
Continuing to pull the battery pack assembly 2 rearward, the support legs 24 cooperate with the frame 16 to support the battery pack assembly 2. As shown in fig. 7, when the two support legs 24 on the front side are disengaged from the frame 16, and are also manually opened or automatically sprung open, the corresponding second pulleys 25 contact the ground, and when the battery pack assembly 2 is completely disengaged from the frame 16, the support legs 24 on the front side and the rear side support the battery pack assembly 2 together. In the whole process, the battery pack assembly 2 always moves through the rolling of the first pulley 23 and the second pulley 25, so that the friction force is small, and the labor is saved. And the battery pack assembly 2 is always in a state of being supported by the frame 16 and/or the supporting legs 24, so that an operator does not need to lift the battery pack assembly 2 or other carrying tools, and the whole disassembly process is very convenient.
The process of installing the battery pack assembly 2 is reverse to the above process, the two rows of first pulleys 23 are aligned with the guide rails 161, then the battery pack assembly 2 is pushed forward, the supporting legs 24 on the front side are folded, when the center of gravity has moved to the frame 16, the supporting legs 24 on the rear side are folded, and after the battery pack assembly 2 is completely installed, the battery pack assembly is installed by installing a stopper (not shown) and covering the rear cover 17. In the whole installation process, the battery pack assembly 2 always moves through the rolling of the first pulley 23 and the second pulley 25, the friction force is less, the labor is saved, the battery pack assembly 2 does not need to be carried by means of tools, and the battery pack assembly 2 does not need to be lifted.
