The counterweight mounting support is fixedly connected to the lithium ion power supply module 10. The various counterweight modules have different mass specifications and are detachably connected to the counterweight mounting support through standardized interfaces. The quick locking mechanism is arranged between the counterweight module and the counterweight mounting support and is used to realize quick installation and disassembly of the counterweight module.

[0042] Embodiment One

[0043] As shown in Figures 1-4 The counterweight module comprises a counterweight block 20, which is fixed to the bottom of the lithium ion power supply module 10 through the counterweight mounting support and is used to increase the counterweight.

[0044] The counterweight mounting bracket comprises a pair of fixed brackets 12 fixedly connected to the two side walls of the lithium ion power supply module 10. Among them, the fixed bracket 12 is in the shape of "L", one side of which is welded and fixed to the side wall of the lithium ion power supply module 10, and a row of first mounting holes 122 is formed on the other side. In addition, a plurality of reinforcing sheets 121 are fixedly connected to the inner corner of the fixed bracket 12, which are in the shape of a triangle. The reinforcing sheets 121 located at the inner corner of the fixed bracket 12 can guarantee the structural strength of the fixed bracket 12 and prevent it from deforming, thereby ensuring the stable and reliable connection between the lithium ion power supply module 10 and the counterweight 20.

[0045] The quick locking mechanism comprises a pre-positioning assembly arranged between the lithium ion power supply module 10 and the counterweight 20, and two rows of first screw holes 21 symmetrically arranged on the counterweight 20. Each row of first screw holes 21 is matched with each row of first mounting holes 122. After aligning the first screw holes 21 with the first mounting holes 122, the lithium ion power supply module 10 and the counterweight 20 can be fixed and installed by using a bolt to pass through the first mounting hole 122 and screw into the first screw hole 21.

[0046] Among them, the pre-positioning assembly comprises a pair of limiting slots 22 formed on the counterweight 20 and a pair of limiting blocks 13 fixed to the bottom of the lithium ion power supply module 10. The pair of limiting slots 22 and the pair of limiting blocks 13 are both in the shape of "T" and matched with each other.
