[0024] Specifically, the upper rotating arm seat 3 and the lower rotating arm seat 14 are welded to the upper and lower parts of the main frame 1 respectively. The structure of the upper rotating arm seat 3 is relatively complex, mainly because the angle adjustment of the upper rotating arm 7 is required, so a rotating arm adjustment motor 2 is installed on the upper part of the upper rotating arm seat 3.

[0025] The motor shaft 4 of the rotating arm adjustment motor 2 is connected to the upper rotating arm 7 via a connecting pin 6, that is, the connecting pin 6 is fixedly connected to the motor shaft 4, for transmitting power to the upper rotating arm 7 to adjust the angle of the upper rotating arm 7, thereby enabling the rotating arm adjustment motor 2 to control the rotation of the upper rotating arm 7.

[0026] A cleaning brush rotating motor 5 is installed at the front of the upper rotating arm 7. The cleaning brush rotating motor 5 is integrally connected with a gearbox 8 and is connected to a cleaning brush shaft 9 through a connecting shaft of the gearbox 8, so that the cleaning brush shaft 9 drives the cleaning brush 10 to rotate and clean the car body.
