[0033] The principles for implementing the present invention are as follows: by transmitting coolant through the circulating liquid cooling system 13, the battery pack 22 can be cooled and dissipated; when maintaining the charging socket area, the plug part 10 can be disengaged from the socket by controlling the plug cylinder 9, and the dust box 8 can be operated to vacuum the internal area of ​​the protective box 4. Furthermore, the intermediate dust suction part 11 can be moved between the plug part 10 and the socket by controlling the electric cylinder 7, and the plug part 10 and the socket can be dusted by the intermediate dust suction part 11.

[0034] When the moving mechanism is working, ventilation and heat dissipation operations can be performed. Specifically, inside the upper box body 1, through the slide seat 20, the outside and the inside of the upper box body 1 are connected through the filter air inlet 6. The air enters from the filter air inlet 6 and can be filtered through the filter air inlet 6 for dust treatment. Then the air enters from the air holes on the execution cylinder 34, is transmitted to the connecting seat 35, and then is transmitted to the transmission box 29, and is released through the air outlet 5 to achieve ventilation cooling, which is beneficial to heat dissipation.

[0035] Furthermore, the dust removal operation can be performed through the execution cylinder 34, that is, the dust and impurities inside the upper box body 1 enter from the air holes on the execution cylinder 34, are transmitted to the connecting seat 35, and then are transmitted to the transmission box 29, and are released through the air outlet 5; specifically, the dust removal operation can be performed on the side and top of the battery pack 22. When the execution cylinder 34 is in a vertical state, the dust removal operation can be performed on the side of the battery pack 22.
