The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In one embodiment, a method for controlling a car washer lateral brush 210 is provided, wherein the car washer comprises: the washing machine comprises a controller, a conveying device, a bracket 201 and a transverse brush 210, wherein the conveying device is used for conveying a vehicle 100 to be washed, and the transverse brush 210 is arranged on the bracket 201; the track of the horizontal brush 210 for cleaning the vehicle 100 to be cleaned sequentially comprises a first section cleaning track and a second section cleaning track, the first section cleaning track comprises the cleaning track before the horizontal brush 210 contacts the antenna 110, and the second section cleaning track comprises the cleaning track when the horizontal brush 210 contacts the antenna 110;

as shown in fig. 5, the method includes:

step S102: when the horizontal brush 210 is located at the first stage of the cleaning track, the controller controls the horizontal brush 210 to rotate reversely.

In one embodiment, the car washer further comprises: an encoder coupled to a motor for driving the conveyor, the encoder for outputting to the controller a coded value indicative of coordinates of the vehicle 100 to be washed; the initial position of the horizontal brush 210 is located at the starting point of the first cleaning track, and the starting point of the first cleaning track corresponds to a first coordinate;

when the horizontal brush 210 is located at the first section of the cleaning track, the horizontal brush 210 is controlled to reversely rotate, which specifically includes:

when the received code value is equal to a first preset code value, determining that the transverse brush 210 is located in a first section of cleaning track and controlling the transverse brush 210 to rotate reversely; wherein, the first preset code value is used for indicating that the head of the vehicle 100 to be washed reaches the first coordinate.

The vehicle 100 to be washed is parked on the chain plate 200, the motor drives the chain plate 200, and the chain plate 200 drives the vehicle 100 to be washed to move forward. The car washing platform is used as a coordinate axis and is divided into a plurality of coordinates corresponding to different code values, and the controller can judge the rotating angle of the code disc according to the received code signals, so that the running length of the chain plate 200 is obtained, and the coordinates of the car are further judged. As shown in fig. 1, the first coordinate is a coordinate of the vehicle 100 to be washed when the vehicle 100 to be washed contacts the horizontal brush 210, and the first coordinate corresponds to a starting point of the first washing trajectory, i.e., a point a. When the code value received by the controller is equal to the first preset code value, it is determined that the horizontal brush 210 is located in the first segment of the cleaning track and the horizontal brush 210 is controlled to rotate reversely. The transverse brush 210 rotates reversely, and the transverse brush 210 can receive the counterforce provided by the vehicle body when being attached to the vehicle body and rotating reversely, so that the transverse brush 210 can brush the vehicle roof from the vehicle head along the engine hood. Meanwhile, the bristles rotating reversely have the same movement direction when contacting with the vehicle body, so that the obstruction of the transverse brush 210 to the vehicle body movement is reduced.

Step S104: when the transverse brush 210 is located at the second segment of the cleaning track, the controller controls the transverse brush 210 to rotate in the forward direction.

In one embodiment, the start point of the second segment of the cleaning track corresponds to a second coordinate;

when the horizontal brush is located second section washing orbit, control horizontal brush forward rotation specifically includes:

when the received code value is equal to a second preset code value, judging that the transverse brush reaches the starting point of a second section of cleaning track and controlling the transverse brush to rotate in the forward direction; and the second preset code value is used for indicating that the vehicle head to be washed reaches the second coordinate.

As shown in the first drawing, when the transverse brush 210 cleans to the starting point of the second cleaning track, that is, point B is in front of the antenna 110, that is, the transverse brush 210 starts to turn when approaching the antenna 110, and the distance from point B to the antenna 110 may be designed according to the requirement, for example, the distance from point B to the antenna 110 is 30 cm. Of course, it is understood that point B may also be the antenna 110 position, i.e., the lateral brush 210 begins to turn when it contacts the antenna 110. When the received code value is equal to a second preset code value, the controller determines that the transverse brush 210 reaches the start point of the second section of the cleaning track and controls the transverse brush 210 to rotate in the forward direction. In addition, for some vehicles with tail wings, since the tail part is also in the second section of the cleaning track, the lateral brush 210 also rotates forward, and the lateral brush 210 brushes the tail in the direction in which the tail extends. When the horizontal brush 210 is located in the second cleaning track, the horizontal brush 210 is controlled to rotate in the forward direction, that is, when the horizontal brush 210 contacts the antenna 110, the horizontal brush 210 rotates in the forward direction to avoid the bristles from winding and damaging the antenna 110 and the tail during rapid rotation.

The design principle of the preset code value is as follows: recording a coordinate (X1, 0) when the vehicle to be washed reaches the starting point of the first section of washing track by taking the length of the car washer as an X axis; with the advance of the vehicle 100 to be washed, the vehicle brush is always attached to the vehicle body, the vehicle to be washed advances, the vehicle brush moves on the vehicle body, when the vehicle brush moves to the starting point of the second section of cleaning track, the coordinate (X2, 0) of the vehicle at the moment is recorded, and the distance of the first section of moving track is X2-X1; the rotating angle of the motor is pushed out according to X2-X1, so that the rotating angle of the coding disc is known, and a corresponding coding value is calculated; the code value is a second preset code value, and when the code value received by the controller is equal to the second preset code value, the transverse brush is controlled to rotate in the forward direction.

In another embodiment, when the vehicle 100 to be washed enters the car washing platform, the position of the antenna 110 of the vehicle 100 to be washed at this time is detected by the sensor, and the coordinates of the vehicle head and the antenna 110 at this time are obtained by the encoder, so as to obtain the coordinate difference between the two. When the coordinate difference between the vehicle head and the coordinates of the transverse brush 210 is equal to the coordinate difference between the vehicle head and the antenna 110, it is determined that the antenna 110 of the vehicle 100 to be washed should have reached the position of the transverse brush 210, i.e., the transverse brush 210 is located in the second section of the washing track. At this time, the controller controls the transverse brush 210 to turn to wash the antenna 110 forward. When the transverse brush 210 is located in the second segment of the cleaning track, the transverse brush 210 is controlled to rotate in the forward direction, that is, when the transverse brush 210 contacts the antenna 110, the transverse brush 210 rotates in the forward direction to avoid winding the antenna 110 or damaging the antenna 110 when the bristles rotate rapidly.

As shown in fig. 2-3, in one embodiment, the reverse direction is a clockwise direction from a left side perspective of the vehicle 100 to be washed, and the forward direction is a counterclockwise direction from a left side perspective of the vehicle 100 to be washed.

Fig. 2 shows that when the horizontal brush 210 is located at the first washing track, the horizontal brush 210 rotates reversely, i.e. clockwise according to the left side view of the vehicle 100 to be washed. Fig. 3 shows the horizontal brush 210 in a second cleaning trajectory, in which the horizontal brush 210 rotates in a forward direction, i.e., counterclockwise direction, as viewed from the left side of the vehicle 100 to be cleaned.

when the received code value is equal to a third preset code value, controlling the moving mechanism to act, so that the moving mechanism drives the transverse brush 210 to move at the same speed as the vehicle 100 to be washed; wherein the third preset code value is used to indicate that the rear of the vehicle 100 to be washed reaches the first coordinate.

When the code value received by the controller is equal to the third preset code value, the vehicle tail reaches the position of the transverse brush 210, and the design principle of the third preset code value is the same as the above. The controller controls the movement mechanism to move, so as to drive the horizontal brush 210 to move at the same speed as the vehicle 100 to be washed. Since the vehicle 100 to be washed is driven by the chain plate 200 to move forward, the speed of the vehicle 100 to be washed is known, and therefore, the transverse brush 210 and the tail of the vehicle 100 to be washed can be kept relatively still only by controlling the speed of the moving mechanism to drive the transverse brush 210 to be the same as the speed of the vehicle 100 to be washed, so that the tail of the vehicle 100 to be washed can be effectively washed.

In one embodiment, the moving mechanism includes a swing arm 204 and a swing cylinder 205, the swing arm 204 is pivotally connected to the lifting arm 202 at one end and is connected to the horizontal brush 210 at the other end, and the swing cylinder 205 is connected to the swing arm 204 at one end and is connected to the support frame 201 at the other end.

As shown in fig. 4, the moving mechanism includes a swing arm 204 and a swing cylinder 205, one end of the swing arm 204 is pivotally connected to the lifting arm 202, the other end of the swing arm is connected to the horizontal brush 210, and one end of the swing cylinder 205 is connected to the swing arm 204, and the other end of the swing cylinder is connected to the support 201. When the code value received by the controller is equal to the second preset code value, the swing cylinder 205 is controlled to extend to drive the transverse brush 210 connected to one end of the swing arm 204 to move in the advancing direction of the vehicle 100 to be washed, and the transverse brush 210 and the tail of the vehicle 100 to be washed can be kept relatively still by controlling the speed of the swing cylinder 205 to drive the transverse brush 210 to be the same as the speed of the vehicle 100 to be washed, so that the tail of the vehicle 100 to be washed can be effectively washed.

In one embodiment, there is provided a car washer including: the washing machine comprises a controller, a conveying device, a bracket 201 and a transverse brush 210, wherein the conveying device is used for conveying a vehicle 100 to be washed, and the transverse brush 210 is arranged on the bracket 201; the track of the horizontal brush 210 for cleaning the vehicle 100 to be cleaned sequentially comprises a first section cleaning track and a second section cleaning track, the first section cleaning track comprises the cleaning track before the horizontal brush 210 contacts the antenna 110, and the second section cleaning track comprises the cleaning track when the horizontal brush 210 contacts the antenna 110;

the controller is configured to:

when the transverse brush 210 is located at the first section of the cleaning track, controlling the transverse brush 210 to rotate reversely;

when the transverse brush 210 is located at the second section of the cleaning track, controlling the transverse brush 210 to rotate in the forward direction;

the reverse direction is a clockwise direction determined from a left side perspective of the vehicle 100 to be washed, and the forward direction is a counterclockwise direction determined from a left side perspective of the vehicle 100 to be washed.

Compared with the prior art, the method has the following beneficial effects:

(1) when the transverse brush 210 is located in the first section of moving track, the transverse brush 210 is controlled to rotate in the forward direction, and when the transverse brush 210 rotates in the reverse direction in fit with the vehicle body, the transverse brush 210 can receive the reaction force provided by the vehicle body, so that the transverse brush 210 can brush the vehicle roof from the vehicle head along the engine hood. Meanwhile, the bristles rotating reversely have the same movement direction when contacting with the vehicle body, so that the obstruction of the transverse brush 210 to the vehicle body movement is reduced.

(2) When the transverse brush 210 is located in the second segment of the moving track, the transverse brush 210 is controlled to rotate in the forward direction, that is, when the transverse brush 210 contacts the antenna 110, the transverse brush 210 rotates in the forward direction to avoid winding the antenna 110 or damaging the antenna 110 when the bristles rotate rapidly.

In one embodiment, the car washer further comprises: an encoder coupled to a motor for driving the conveyor, the encoder for outputting to the controller a coded value indicative of coordinates of the vehicle 100 to be washed; the initial position of the horizontal brush 210 is located at the starting point of the first cleaning track, and the starting point of the first cleaning track corresponds to a first coordinate;

when the horizontal brush 210 is located at the first section of the cleaning track, the horizontal brush 210 is controlled to reversely rotate, which specifically includes:

when the received code value is equal to a first preset code value, determining that the transverse brush 210 is located in a first section of cleaning track and controlling the transverse brush 210 to rotate reversely; wherein, the first preset code value is used for indicating that the head of the vehicle 100 to be washed reaches the first coordinate.

In one embodiment, the start point of the second segment of the cleaning track corresponds to a second coordinate;

when the horizontal brush 210 is located in the second section of the cleaning track, the horizontal brush 210 is controlled to rotate in the forward direction, which specifically includes:
