The dustproof cloth effectively filters dust particles in the air, ensuring clean air entering the battery box, reducing dust corrosion of the battery, and improving the battery's operational stability.

[0025] 8. The cooling assembly uses a square cooling frame that snaps into the installation gap, with the condenser installed inside the frame. This snap-fit ​​installation method facilitates maintenance and replacement. The condenser absorbs heat from the air, further reducing the temperature of the air entering the battery compartment. Working in conjunction with heat sinks and other heat dissipation structures, it significantly improves the battery compartment's heat dissipation capacity, providing a more suitable working environment for the battery.

Meanwhile, a sunken groove 11 capable of accommodating the motor 43 is formed in the outer box body 1, and a groove cover 12 is further covered on the groove opening of the sunken groove 11 to avoid the exposure of the motor 43. In order to further improve the controllability of the rotating frame 4, two motors 43 are arranged for each rotating frame 4, so as to reduce the risk of being unable to adjust due to damage of a single motor 43.
