[0036] As Figure 2 shown in the drawings, the clamping assembly 300 comprises a moving base 310, the moving base 310 is slidably connected to the clamp base 100 along the first direction, and the top of the moving base 310 is slidably connected with a push plate 320.

The push plate 320 can abut against the single battery 10. First, the moving base 310 drives the push plate 320 and the driving member 330 to move to the appropriate position, realizing the rough positioning of the push plate 320 and the single battery 10, and then driving the push plate 320 to further approach the single battery 10 through the driving member 330, using the push plate 320 to abut against the side wall of the single battery 10, realizing the clamping and fixing of the single battery 10. The above structure is simple and convenient, and can reduce the maintenance cost of the battery clamp.

[0037] Specifically, the clamp base 100 is provided with a second guide rail 120 extending along the first direction, and a plurality of second guide rails 120 are arranged at intervals, specifically two second guide rails 120.

When the push plate 320 contacts the single battery 10, the clamp 331 is pressed down at this time, so that the cam of the clamp 331 rotates and pushes the push rod 332 forward, and the push rod 332 can apply a pushing force along the first direction to the push plate 320. The clamp 331 is fixed while realizing the abutment and fixation of the push plate 320 of the clamping assembly 300 to the single battery 10.

[0039] Further, the clamping assembly 300 further comprises a connecting bracket 340, a bottom of the connecting bracket 340 is slidingly connected to the moving base 310, the connecting bracket 340 is connected with the push plate 320, and an elastic member 341 extending along the first direction is arranged between the push plate 320 and the connecting bracket 340. In the process of abutting against the single battery 10, if the push plate 320 is subjected to too large a pushing force, the single battery 10 will be damaged due to extrusion. The arrangement of the elastic member 341 can control the pushing force to which the push plate 320 is subjected, the extrusion force to which the elastic member 341 is subjected is the pushing force to which the push plate 320 is subjected, that is, the arrangement of the elastic member 341 can play a buffering role, so that the single battery 10 is not damaged due to extrusion when the single battery 10 is clamped and fixed by the battery clamp, and the reliability in use is improved.

[0040] Specifically, the top wall of the moving base 310 is provided with a third guide rail 313 extending along the first direction, and the connecting bracket 340 is slidingly connected to the third guide rail 313.

In this embodiment, the moving base 310 can be freely moved along the first direction on the top wall of the clamp base 100. When the moving base 310 is moved into position, the fixing pin 311 is inserted into the pin hole 312 and into the corresponding positioning hole 110, thereby fixing the moving base 310 and the clamp base 100, limiting the movement of the moving base 310, avoiding the failure of the clamping assembly 300 to fix the single battery 10 during the movement of the battery clamp, and improving the use reliability of the battery clamp.

In this embodiment, the lifting seat 410 is used to lift the fixing boss 420, and the fixing boss 420 protrudes from the top wall of the bearing table 200 after being lifted. After the bearing table 200 bears the single battery 10 placed in the third direction, the fixing boss 420 and the clamping assembly 300 jointly clamp and fix the single battery 10.

Specifically, the lifting seat 410 is provided with a sliding block, and the bearing table 200 fixed on the clamp base 100 is provided with the first guide rail 230. The first guide rail 230 is spaced apart along the first direction, specifically two first guide rails 230, and the bearing table 200 is provided with two first guide rails 230 on the two opposite inner walls along the third direction, and the two first guide rails 230 are symmetrically arranged. The first guide rail 230 is used for guiding and positioning the movement of the lifting seat 410, so as to ensure that the lifting seat 410 drives the fixed boss 420 to move accurately and smoothly along the third direction to the preset position, and to realize reliable fixing of the single battery 10.
