The two movable pins 320 in each positioning assembly 300 are slidably connected to the corresponding positioning plates 310 in opposite or away directions for inserting into or removing from the lifting holes on both sides of the battery pack.

[0022] During implementation, the three-axis moving assembly 100 drives the connecting frame 200 to move to directly above the battery pack, and the four positioning plates 310 are respectively located on both sides of the battery pack. Adjust the position of the connecting frame 200 so that the four movable pins 320 move to directly face the four lifting holes on both sides of the battery pack, and the four movable pins 320 are respectively inserted into the four lifting holes, thus completing the connection process between the connecting frame 200 and the battery pack. This lifting device will not cause damage to the battery pack during the process of transporting the battery pack.

[0023] The three-axis moving assembly 100 in this implementation scheme is a structure that drives the connecting frame 200 to move for transporting the battery pack connected to the connecting frame 200 into the shelves of the container.

[0024] In one embodiment, the three-axis moving assembly 100 includes a gantry 110, an XY-axis moving member 120, and a Z-axis moving member 130.

[0025] Among them, the XY-axis moving member 120 can be implemented by using the structure of a cylinder and a slide rail. At the same time, the Z-axis moving member 130 can be implemented by using a hoist wire. In this regard, the present application does not limit the structure of the three-axis moving assembly 100, as long as it can stably drive the connection frame 200 to move.

[0026] The connection frame 200 in this embodiment is rectangular and connected to the mobile end.

[0027] To adapt to battery packs of different model sizes, in one embodiment, further, the connection frame 200 includes two relatively arranged cross plates 210 and two relatively arranged longitudinal plates 220. The two cross plates 210 and the two longitudinal plates 220 are connected end to end to form a frame structure. A plurality of threaded holes 211 are formed in the cross plates 210 along their length directions. The longitudinal plates 220 and the positioning plates 310 can be connected to any of the threaded holes 211 to adjust the lateral position between the four positioning plates 310 and the distance between the two longitudinal plates 220.

[0028] To facilitate adjusting the position of the connection frame 200 relative to the battery pack, in this embodiment, a handle 212 is further installed on the cross plate 210, which is convenient for the operator to control the movement of the connection frame 200.

[0029] Among them, the longitudinal plate 220 includes a fixed plate 221, two sliding plates 222, and an adjusting member 223. The two sliding plates 222 are respectively connected to the two cross plates 210 on the opposite sides. The opposite sides of the two sliding plates 222 are slidably connected to the fixed plate 221 along its length direction via the adjusting member 223 to adjust the distance between the two cross plates 210.

The two movable pins 320 in each positioning component 300 are slidably connected to the corresponding positioning plate 310 in the relative or opposite direction for inserting into or removing from the lifting holes on both sides of the battery pack.

[0034] The movable pin 320 can be manually pushed into the lifting hole. Of course, for the convenience of driving the movement of the movable pin 320, in one embodiment, a driving member is further included and installed on the positioning plate 310. The output end of the driving member is connected to the movable pin 320 for driving the movable pin 320 to move closer to or away from the opposite movable pin 320. Among them, the driving member can be realized by a cylinder. A plurality of cylinders are connected in parallel and connected to a switch installed on the connection frame 200, and the plurality of cylinders can be synchronously controlled through the switch.

[0035] To facilitate knowing whether the movable pin 320 is completely inserted into the lifting hole, a pressure sensor is further included and installed at the free end of the movable pin 320 in this embodiment. When the pressure sensor contacts the bottom wall of the lifting hole and detects a pressure value, it represents whether the movable pin 320 is completely inserted into the lifting hole.

[0036] To more intuitively display the above process, an induction lamp electrically connected to the pressure sensor is further included in this embodiment. The induction lamp is fixedly arranged on the side of the positioning plate 310 away from the movable pin 320.

[0037] Compared with the prior art: The three-axis moving component 100 drives the connection frame 200 to move directly above the battery pack, and the four positioning plates 310 are respectively located on both sides of the battery pack. The position of the connection frame 200 is adjusted so that the four movable pins 320 move to directly face the four lifting holes on both sides of the battery pack, and the four movable pins 320 are respectively inserted into the four lifting holes, thus completing the connection process between the connection frame 200 and the battery pack. This lifting tool will not cause damage to the battery pack during the process of transporting the battery pack.
