DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] See Figures 1-5, the utility model relates to a quick disassembly and assembly device for a battery PACK, which includes a fixed frame 1, a lifting platform 2 for driving the fixed frame 1 to lift, a moving slide 3, a screw lifter 4 and a manual winch 5. The fixed frame 1 is placed on the lifting platform 2, and the lifting platform 2 drives the fixed frame 1 to lift. A screw lifter 4 is installed in the fixed frame 1, and the screw 4.1 of the screw lifter 4 is horizontally arranged. The screw nut 4.2 of the screw lifter 4 is fixedly connected to the moving slide 3, and the screw nut 4.2 drives the moving slide 3 to move horizontally in the fixed frame 1. In order to ensure the stable translation of the moving slide, sliding guide rails 6 are provided on the inner walls of both sides of the fixed frame 1, and guide rail sliders 7 corresponding to the sliding guide rails 6 are provided on the outer walls of both sides of the moving slide 3.

[0021] Two manual winches 5 are symmetrically arranged on both sides of the fixed frame 1 through winch mounting plates 8. The manual winches 5 are located at the rear end of the fixed frame 1, and the two winch mounting plates 8 are symmetrically installed on the left and right sides of the fixed frame 1.

[0022] A steel wire rope 9 is wound on the manual winch 5, and the movable end of the steel wire rope 9 is connected to a buckle 10. The battery PACK 11 is provided with a fixed ear 12 corresponding to the buckle 10.

[0023] A limiting block 3.1 is provided at the rear end of the moving slide 3 corresponding to the battery PACK 11.

[0024] The screw lifter 4 includes a worm and gear reducer 4.3 and a screw 4.1 adapted to the worm and gear reducer 4.3. The worm and gear reducer 4.3 is fixed at the rear end of the fixed frame 1. A screw nut 4.2 is sleeved on the screw 4.1, and the free end of the screw 4.1 is fixed at the front end of the fixed frame 1 through a screw bearing 13. The input end of the worm and gear reducer 4.3 is connected to a hand crank or a driving motor to drive the screw 4.1 to rotate, and the screw nut 4.2 drives the moving slide 3 thereon to move horizontally.

[0025] Working principle:

[0026] When disassembling the battery PACK, the lifting platform 2 drives the fixed frame 1 to be adjusted to an appropriate height. Connect the buckle 10 at the movable end of the steel wire rope 9 of the two manual winches 5 to the fixed ear 12 of the battery PACK 11, and rotate the manual winch 5. The steel wire rope 9 drags the battery PACK 11 from the battery cluster frame onto the moving slide 3 to realize the disassembly of a single battery PACK.

[0027] When the battery PACK is installed, place the battery PACK 11 on the moving slide 3 and limit it by the limit block 3.1. Manually or electrically drive the screw lifter 4. The screw 4.1 rotates, driving the screw nut 4.2 to drive the moving slide 3 forward. Since the limit block 3.1 is located behind the battery PACK 11, when the moving slide 3 continues to move forward, the limit block 3.1 slowly pushes the battery PACK 11 into the battery cluster rack, realizing the installation of a single battery cluster rack.
