When cleaning the front or rear of the car, the frame assembly 1 drives the vertical brush beam 3 to move towards the front or rear of the car continuously. When the vertical brush 2 contacts the front or rear of the car, the vertical brush 2 will be stressed and move along the frame. The moving direction of the assembly 1 is inclined, and the vertical brush beam 3 also rotates around the rotating shaft 4. During this process, the corresponding trigger lever 37 gradually rotates toward the contact of the first contact limit switch 36 until the first contact limit switch is triggered. Switch 36. At this time, the central controller controls the frame drive mechanism to stop running and controls the frame drive mechanism to run in reverse for a period of time.

When the frame drive mechanism runs in reverse The trigger rod 37 that triggers the first contact limit switch 36 is disengaged to trigger the first contact limit switch 36. At this moment, the central controller controls the frame drive mechanism to stop running and controls the rotation drive mechanism 24 to start, and the vertical brush 2 will maintain the same The front or rear of the car is attached to the inclined state and rotates around its own axis to realize the brushing of the front or rear of the car.

Referring to Fig. 5, if the frame assembly 1 does not stop when it should be stopped, or the vertical brush 2 is pushed at an excessively large tilt angle due to the movement of the body itself due to the driver's misoperation, the vertical brush 2 will gradually form between the front or rear of the vehicle. Rigid contact, thereby causing damage to the body or causing potential safety hazards, for this reason, two limit rods 39 are fixed at one end of the vertical brush beam 3, and the side of the frame assembly 1 close to the end of the vertical brush beam 3 is fixed with the central control The second contact limit switch 38 is coupled to the device, the contact extension direction of the second contact limit switch 38 is parallel to the extension direction of the vertical brush beam 3, and the two limit rods 39 are located at the second contact limit switch. On both sides of the contacts of the switch 38, the distance between the two limit rods 39 is greater than the distance between the two trigger rods 37, and the axes of the two limit rods 39 are both located in the vertical direction extending along the moving direction of the frame assembly 1. In the straight plane; before the limit lever 39 triggers the second contact limit switch 38, the trigger lever 37 must have contacted the contact of the first contact limit switch 36, and when the second contact limit switch 38 is triggered , the contact of the first contact limit switch 36 has been deformed. Therefore, the first contact limit switch 36 and the second contact limit switch 38 both use coil spring strokes with deformable contacts and automatic reset. Switch, in this embodiment, a coil spring type travel switch with model WL01NJ is used.

When the tilting angle of the vertical brush 2 is too large and the first contact limit switch 36 has been triggered, the limit rod 39 will gradually approach the contact of the second contact limit switch 38, and the central controller controls the All drive mechanisms of the vertical brush device including the rotary drive mechanism 24 , the frame drive mechanism, and the lateral drive mechanism 9 are stopped to prevent damage to the vehicle body or potential safety hazards due to the continuous approach of the vertical brush 2 to the front or rear of the vehicle.

This specific embodiment is only an explanation of the application, and it does not limit the application. Those skilled in the art can make modifications to the embodiment without creative contribution as needed after reading this specification, but as long as the rights of the application are All claims are protected by patent law.
