A motor 27 is mounted on the slide block 16, which is used to drive the lead screw 3001.

[0031] A moving mechanism is provided inside the upper housing 1 for ventilation, heat dissipation, dust removal, and expansion detection. The moving mechanism includes a moving seat 23 that is slidably installed inside the upper housing 1. A lifting platform 26 is raised and lowered on the moving seat 23.

A connecting seat 35 is rotatably installed on the moving frame 31. An actuator cylinder 34 is rotatably installed on the connecting seat 35. A detector is provided on the bottom side of the actuator cylinder 34.

[0032] The moving mechanism is driven by lead screw 18; the moving seat 23 on the moving mechanism is slidably fitted on lead screw 18 and guide rod 19, and guide rod 19 and moving seat 23 form a helical pair; a transmission box 29 is provided on the lifting platform 26, and the top of the transmission box 29 is connected to the air outlet 5; a lifting electric cylinder 24 is provided on the moving seat 23, which is used to control the movement of the lifting platform 26; a motor 27 is provided on the lifting platform 26, and a gear 28 is provided on the output shaft of the motor 27; a gear ring 25 is rotatably mounted on the lifting platform 26, and the gear ring 25 and gear 28 form a gear pair; a drive lead screw 3001 is rotatably mounted on the lifting platform 26, and one end of the drive lead screw 3001 is connected to a lead screw gear 30, and the lead screw gear 30 and gear ring 25 form a gear pair; the drive lead screw 3001 is used to drive the actuator; the movable frame 31 on the actuator and the drive screw 3001 form a screw pair; the first rotating motor 32 has a hollow structure and is connected to the transmission box 29; the actuator cylinder 34 sucks up dust and transmits it to the transmission box 29; the movable frame 31 is equipped with a second rotating motor 33 for driving the connecting seat 35; the first rotating motor 32 is installed on the top of the connecting seat 35 for driving the actuator cylinder 34; the actuator cylinder 34 has a hollow structure and air holes are arranged on its surface and top; the detector includes a telescopic contact rod 36 that is telescopically arranged on the bottom side of the actuator cylinder 34; a pressure-sensitive detection sensor 37 is arranged between the telescopic contact rod 36 and the bottom side of the actuator cylinder 34; the pressure-sensitive detection sensor 37 is used to detect and feedback the telescopic displacement change of the telescopic contact rod 36.

[0033] The principle of this invention is as follows: Coolant is transferred through the circulating liquid cooling system 13 to dissipate heat from the battery pack 22; when maintaining the charging port area, the plug part 10 can be disengaged from the port by controlling the plug cylinder 9, and the dust collection box 8 can work to vacuum the internal area of ​​the protective box 4. Furthermore, the intermediate dust collection part 11 can be moved between the plug part 10 and the port by controlling the electric cylinder 7, and the intermediate dust collection part 11 can perform dust removal operation on the plug part 10 and the port.

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

[0035] Furthermore, dust removal can be performed via the actuator 34. Dust and impurities inside the upper housing 1 enter through the air vent on the actuator 34, are transported to the connecting seat 35, and then to the transmission box 29, where they are released through the air outlet 5. Specifically, dust removal can be performed on the sides and top of the battery pack 22. When the actuator 34 is in a vertical position, dust removal can be performed on the sides of the battery pack 22; when the actuator 34 is in a horizontal position, dust removal can be performed on the top of the battery pack 22. The actuator 34 is driven by the rotating motor 33 to achieve deflection, switching between vertical and horizontal states. It can also be operated by the motor 27, which, under gear transmission, causes the gear ring 2... 5. Rotation causes the lead screw gear 30 and drive lead screw 3001 to rotate, and the moving frame 31 to slide, thereby adjusting the position of the moving frame 31, that is, adjusting the position of the actuator cylinder 34 and the side of the battery pack 22. The lifting platform 26 can be moved by the lifting cylinder 24 to adjust the height position of the actuator cylinder 34. When the motor 12 works, the lead screw 15 rotates and the slide 16 moves, completing the first direction adjustment of the moving mechanism. When the motor 27 works, the lead screw 28 rotates and the moving seat 23 moves, completing the second direction adjustment of the moving mechanism, so that the mechanism can be positioned inside the upper housing 1 to be located at the position of each battery pack 22.

[0036] When the actuator 34 is located on the side of the battery pack 22 and is in a vertical position, it can detect the expansion of the side of the battery pack 22, that is, detect whether the surface of the battery pack 22 is bulging. Specifically, by adjusting the position of the actuator 34, the telescopic contact rod 36 is brought into contact with the surface of the battery pack 22. By moving and adjusting, the telescopic contact rod 36 moves on the surface of the battery pack 22. When it passes through the bulging area, the telescopic contact rod 36 extends and retracts. The pressure-sensitive detection sensor 37 detects and provides feedback on the extension and retraction displacement of the telescopic contact rod 36, thereby completing the detection of the bulging area. This can remind the operator to replace and maintain the battery pack in a timely manner to avoid safety hazards.
