[0006] The front, rear, left, and right position mechanism is used to adjust the front and rear relative position of the battery, and comprises: a cylinder (1), a guide rail (2), a floating joint (4), a guide rail base plate (13), and a base plate (21); the guide rail (2) is arranged on the base plate (21); the guide rail base plate (13) is arranged on the guide rail (2) and slides on the guide rail; the cylinder (1) is connected to the guide rail base plate (13) via the floating joint (4) to drive the guide rail base plate to move forward and backward;

[0007] The battery rotating top angle folding mechanism is arranged above the guide rail bottom plate (13), and comprises: a first motor (12), a second motor (27), a linear guide rail (3), a second guide rail (5), a synchronous wheel, a synchronous belt, and a ball screw. The first motor (12) drives the battery rotating top angle folding mechanism to move left and right through the synchronous wheel, the synchronous belt, and the ball screw, and then rotates the second motor (27) to flatten the battery top angle on the battery sealing edge.

[0008] Beneficial Effects

[0009] Prevent the diaphragm and pole pieces inside the battery from being stretched and damaged, causing battery short circuit and unstable current. BRIEF DESCRIPTION OF THE DRAWINGS
