[0039] When installing the battery body 1, place it in the limit frame 61, support it through the support movable plate 67, and then rotate the threaded assembly rod 24 to drive the bearing drive plate 3 to move downward under the action of the thread. As the bearing drive plate 3 moves downward, the two closed door panels 38 will be driven to move toward each other under the action of the first supporting connecting rod 37, covering the box opening of the battery carrying box 2, but not closed together, so that the battery body 1 can be protected under the action of the battery carrying box 2 and the closed door panels 38. In addition, when the bearing drive plate 3 moves downward, the support base frame 4 and the bearing drive plate 3 will be The distance between them becomes smaller, so that under the action of the second support connecting rod 42, the movable carrying plate 5 will be driven to move in the direction of the carrying driving plate 3, and then the connecting carrying plate 7 will be driven to move so that the support locking rod 74 is inserted into the support fixing hole 11, so as to realize the support and fixation of the battery body 1.

When the shock-absorbing strip 8 moves upward, the piston plate 86 will be pushed to move into the piston chamber 58 under the action of the third supporting connecting rod 82. In this way, the air in the piston chamber 58 can be blown out from the blowing pipe 581 under the action of the piston plate 86, so that the wind blows toward the battery body. 1 can play a certain role in assisting heat dissipation.
