In the process that the vertical brush cross beam 3 rotates around the rotating shaft 4, the situation that one spring 7 is shortened and the other spring 7 is lengthened is generated, and the two springs 7 generate torque opposite to the rotation direction of the vertical brush cross beam 3 to the opposite brush cross beam 3, so that the vertical brush 2 can be attached to the head or the tail of a vehicle more tightly; in addition, after the frame assembly 1 drives the vertical brush 2 and the vertical brush beam 3 to be separated from the vehicle head or the vehicle tail, the vertical brush beam 3 can be automatically reset under the action of the two springs 7 so that the vertical brush 2 is in a vertical state.

Referring to fig. 5, two trigger rods 37 are fixed at one end of the vertical brush beam 3, and a first contact limit switch 36 coupled with the central controller is fixed at one side of the frame assembly 1 close to the end of the vertical brush beam 3, the extending direction of a contact of the first contact limit switch 36 is parallel to the extending direction of the vertical brush beam 3, the two trigger rods 37 are respectively located at two sides of the contact of the first contact limit switch 36, and the axes of the two trigger rods 37 are both located in a vertical plane extending along the moving direction of the frame assembly 1; when the vertical brush 2 does not generate an included angle in a direction perpendicular to a vertical plane on which the axis of the rotating shaft 4 is located, the contact of the first contact type limit switch 36 is located at the middle between the two trigger rods 37.

When the vehicle head or the vehicle tail is cleaned, the frame assembly 1 drives the vertical brush beam 3 to move towards the direction close to the vehicle head or the vehicle tail continuously, when the vertical brush 2 contacts the vehicle head or the vehicle tail, the vertical brush 2 is stressed and inclines along the moving direction of the frame assembly 1, the vertical brush beam 3 also rotates around the rotating shaft 4, in the process, the corresponding trigger rod 37 gradually rotates towards the contact close to the first contact limit switch 36 until the first contact limit switch 36 is triggered, at the moment, the central controller controls the frame driving mechanism to stop running and controls the frame driving mechanism to run reversely for a period of time, when the frame driving mechanism stops, the frame assembly 1 and the vertical brush 2 stop going forward, when the frame driving mechanism runs reversely, the trigger rod 37 triggering the first contact limit switch 36 is separated from the first contact limit switch 36, and at the moment, the central controller controls the frame driving mechanism to stop running and controls the rotary driving mechanism 24 to start, the vertical brush 2 keeps an inclined state attached to the head or the tail of the vehicle and rotates around the axis of the vertical brush to realize the brushing of the head or the tail of the vehicle.

Referring to fig. 5, if the frame assembly 1 should be stopped, or if the tilting angle of the vertical brush 2 is too large due to the movement of the vehicle body caused by the misoperation of the driver, the vertical brush 2 will gradually form a rigid contact with the vehicle head or the vehicle tail, further causing damage to the car body or causing potential safety hazard, for this reason, one end of the vertical brush beam 3 is fixed with two limiting rods 39, and one side of the frame assembly 1 close to the end of the vertical brush beam 3 is fixed with a second contact limit switch 38 coupled with the central controller, the extending direction of the contact of the second contact limit switch 38 is parallel to the extending direction of the vertical brush beam 3, two limit rods 39 are respectively positioned at two sides of the contact of the second contact limit 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 stop rods 39 are both located in a vertical plane extending along the moving direction of the frame assembly 1; before the limit rod 39 triggers the second contact limit switch 38, the trigger rod 37 will contact the contact of the first contact limit switch 36, and after the second contact limit switch 38 triggers, the contact of the first contact limit switch 36 will be deformed, for this reason, both the first contact limit switch 36 and the second contact limit switch 38 adopt a coil spring type travel switch with deformable contact and capable of automatic resetting, in this embodiment, a coil spring type travel switch model WL01NJ is adopted.

When the tilting angle of the vertical brush 2 is too large and the first contact limit switch 36 is triggered, the limit rod 39 will gradually approach the contact of the second contact limit switch 38, and at this time, the central controller controls all driving mechanisms of the vertical brush device including the rotary driving mechanism 24, the frame driving mechanism, the transverse driving mechanism 9 and the like to stop operating, so as to prevent the vertical brush 2 from continuously approaching the head or tail of the vehicle to damage the vehicle body or cause potential safety hazards.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
