Two conductive posts 3 are fixedly connected to the side wall and the bottom of each battery module 1. The conductive posts 3 are adapted to the docking slots 2. Several first positioning strips 4 are fixedly connected to the side wall of the conductive posts 3. Each docking slot 2 is provided with a conductive cylinder 5. Several second positioning strips 6 are fixedly connected to the inner wall of the conductive cylinder 5. The first positioning strips 4 and the second positioning strips 6 are adapted to each other.

[0025] A clamping component is provided in the docking groove 2, and a connecting component is provided on the left and right side walls of the battery module 1.

[0026] like Figure 3 As shown, the clamping assembly includes a screw 7 rotatably connected to the bottom surface of the docking groove 2, a threaded sleeve 8 fixedly connected to the bottom surface of the guide cylinder 5, the screw 7 and the threaded sleeve 8 being threadedly connected, and worm gears 9 being fixedly connected to the side walls of the screw 7. After the two worm gears 9 mesh at their rear sides, there is a common worm 10. The worm 10 is rotatably connected to the battery module 1, and a rotating wheel 11 is fixedly connected to the left end of the worm 10.

[0027] Both the first positioning strip 4 and the second positioning strip 6 are trapezoidal structures, and the first positioning strip 4 and the second positioning strip 6 are arranged opposite to each other.

[0028] When the conductive post 3 is inserted into the docking groove 2, the first positioning strip 4 and the second positioning strip 6 are interlocked. Through the cooperation of the trapezoidal structure, the side wall of the first positioning strip 4 and the side wall of the second positioning strip 6 are tightly attached to each other. Both the first positioning strip 4 and the second positioning strip 6 are made of high-quality conductive materials such as aluminum and copper, which can realize the stable transmission of electrical energy and prevent problems such as electric arc and excessive temperature caused by poor connection, thereby enhancing the circuit safety performance.

[0029] like Figure 1 andFigure 4 As shown, the connecting assembly comprises a movable plate 12 rotatably connected to the left and right side walls of the battery module 1 near the bottom surface, the side wall of the movable plate 12 is provided with a groove 13, the left and right side walls of the battery module 1 are fixedly connected with hanging rods 14 near the top surface, the groove 13 corresponds to the hanging rod 14, and the top surface of the groove 13 is provided with a limiting assembly.

[0030] When it is necessary to combine multiple battery modules 1 for use, the upper and lower battery modules 1 can be hung by cooperation between the movable plate 12 and the hanging rod 14, and the battery modules 1 can be used as a whole during carrying or transporting, so that the power supply capacity is larger, the power is higher, and the power supply time is longer.
