DETAILED DESCRIPTION

[0041] To make the technical features of the present scheme clear, the present utility model will be described in detail below through specific implementation manners and in combination with the accompanying drawings.

[0042] It should be noted that in the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model can also be implemented in other manners different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0043] As shown in the figure, in order to facilitate description, a right-hand rectangular coordinate system is adopted in the present utility model, and the x-axis direction is also described as rightward, and the z-axis direction is also described as downward. Figures 1-5

[0044] The mobile side brush structure provided by the present utility model is applied to a car washing machine, and specifically comprises a y-axis frame 100, an x-axis frame 200, an x-axis guide rail 300, an x-axis moving seat 400 and a side brush shaft 500.

[0045] Among them, the y-axis frame 100 can move along the y-axis direction on the y-axis guide rail (not shown in the figure) provided by the car washing machine; the x-axis frame 200 is installed on the y-axis frame 100; the x-axis guide rail 300 is installed on the x-axis frame 200, and the x-axis guide rail 300 is arranged along the x-axis; the x-axis moving seat 400 can move along the x-axis direction on the x-axis guide rail 300; the side brush shaft 500 is installed on the x-axis moving seat 400, the side brush shaft 500 can rotate around the z-axis, and the side brush shaft 500 is used for installing the side brush 510.

[0046] Generally, the number of x-axis moving seats 400 is two, and two side brushes 510 can be installed to wipe the vehicle from left and right. The y-axis frame adopts a rectangular frame, and the x-axis frame 200 is installed on the inner side of the y-axis frame.

[0047] ​When working, the vehicle is parked on the top of the conveying belt on the ground, the y-axis frame 100 is located in front of the vehicle at the beginning, the two x-axis moving seats 400 are moved from left and right to the middle, the side brushes 510 on the side brush shafts 500 contact the vehicle body, and the side brushes 510 are driven to clean the vehicle body through the rotation of the side brush shafts 500.

[0048] During the wiping process, the conveying belt drives the vehicle to move forward along the y-axis. At the same time, the two x-axis moving seats 400 are moved from the middle to left and right, and the y-axis frame 100 also needs to move forward with the vehicle to avoid the vehicle advancing to abut against the side brushes 510 on the x-axis moving seats 400 to cause an accident.

[0049] When the two side brushes 510 are moved to left and right sides of the vehicle body respectively, the y-axis frame 100 switches the moving direction to drive the side brushes 510 to move to the tail of the vehicle. During the moving process, the side brushes 510 continue to contact the vehicle body to wipe the vehicle body, and when the tail of the vehicle is wiped, the two x-axis moving seats 400 drive the side brushes 510 to start to move to the middle to wipe the tail of the vehicle.

[0050] During the wiping process of the tail of the vehicle, the vehicle keeps moving forward, so the y-axis frame 100 needs to switch to move forward with the vehicle to enable the side brushes 510 to keep contacting the vehicle body. After the tail of the vehicle is wiped, the y-axis frame 100 and the x-axis moving seats 400 return to the initial positions, so that the above operation can be repeated to wipe and clean the subsequent vehicle.
