Description

Technical Field

[0001] This application belongs to the field of automatic car wash technology, specifically relating to an automatic brushing device and method for preventing jamming on the side of a vehicle. Background Technology

[0002] In existing technologies, vehicle side washing equipment plays a crucial role in automated car wash operations. It can specifically clean the sides of the vehicle, improving the overall cleanliness and thoroughness of the wash, ensuring wash quality, meeting car owners' cleaning needs, and simultaneously increasing the operational efficiency of automated car wash equipment to adapt to large-scale continuous car wash scenarios. However, current vehicle side washing equipment on the market has some shortcomings.

[0003] In existing technologies, to meet the washing needs of vehicle sides, a structure with upright roller brushes is typically used. The upright roller brushes are driven to adhere to the vehicle sides for thorough washing. However, such vehicle side washing equipment generally lacks anti-jamming functionality. When the vehicle side washing equipment malfunctions, the automatic car wash line's conveyor system continues to transport vehicles to the side washing equipment according to a preset program. This results in excessive collisions between the vehicles and the malfunctioning equipment, potentially leading to jamming. During continuous car wash operations, this problem can cause subsequent collisions between multiple vehicles, resulting in paint scratches, dents, and other damage, causing financial losses for car owners. Furthermore, it can exacerbate the malfunction of the side washing equipment, paralyzing the entire automatic car wash line and severely impacting the continuity and efficiency of the washing operation.

[0004] Therefore, in order to comprehensively improve the safety, reliability, operational stability, and protection of vehicles and equipment, avoid jamming and collision accidents, and ensure the smooth operation of continuous car wash operations, it is now urgent to make improvements to enhance the user experience and the overall effect of automatic car wash operations. Summary of the Invention

[0005] This application addresses the technical problem that existing vehicle side-washing devices generally lack anti-jamming functionality. When the equipment malfunctions, the automatic car wash line's conveyor continues to transport vehicles according to a preset program, leading to excessive collisions or even jamming between the vehicles and the malfunctioning side-washing device. During continuous car wash operations, this can cause multiple vehicles to collide in succession, resulting in damage such as scratches and dents, exacerbating the malfunction of the side-washing device, and even paralyzing the entire automatic car wash line, severely affecting the continuity and efficiency of car wash operations. Therefore, this application proposes an anti-jamming automatic side-washing device for vehicles.

[0006] In order to solve the technical problems raised in this application, this application also provides a method for preventing jamming in an automatic side washing device for vehicles.

[0007] This application adopts the following solution: This application provides an automatic anti-jamming washing device for the side of a vehicle, including a support mechanism, a washing mechanism rotatably disposed at one end of the support mechanism, a washing station disposed between the support mechanism and the washing mechanism, and an anti-jamming mechanism disposed between the washing mechanism and the support mechanism. The anti-jamming mechanism includes a drive component disposed between the washing mechanism and the support mechanism, and a damping buffer component disposed between the washing mechanism and the support mechanism. The output end of the drive component is disposed on the washing mechanism, and the movable end of the damping buffer component is disposed on the washing mechanism. When the vehicle to be washed is placed in the washing station, the drive component can be used to drive the washing mechanism to rotate away from the vehicle to be washed.

The plurality of rotating arms and the plurality of vertical brushes together form the scrubbing station, and the anti-jamming mechanism is disposed between the rotating arm and the support mechanism.

[0009] In some feasible embodiments, the scrubbing mechanism further includes an angle adjustment mechanism disposed between the rotating arm and the support mechanism, the angle adjustment mechanism being used to adjust the tilt angle of the rotating arm relative to the support mechanism in the vertical direction.

[0010] In some feasible embodiments, the angle adjustment mechanism includes a plurality of adjustment holes disposed at one end of the rotating arm near the support mechanism, an adjustment column disposed on the support mechanism at the corresponding position of the adjustment hole, and a fastener disposed on the adjustment column. The cross-sectional shape of the adjustment hole is racetrack-shaped, and the plurality of adjustment holes are spaced apart around the center of the rotating arm.

[0011] In some feasible embodiments, the scrubbing mechanism further includes limiting components disposed on both sides of the rotating arm, the limiting components being used to limit the rotation angle of the rotating arm relative to the support mechanism.

[0012] In some feasible embodiments, the limiting component includes limiting seats on both sides of the rotating arm, limiting posts on the limiting seats, and buffer blocks on the limiting posts near one end of the rotating arm. When the rotating arm rotates relative to the support mechanism, the buffer blocks can abut against the side of the rotating arm to limit the rotation angle of the rotating arm.

[0013] In some feasible embodiments, a boss is also provided between any of the rotating arms and the support mechanism, the boss being used to stagger the arrangement of two adjacent rotating arms.

[0014] In some feasible embodiments, the upright brush is rotatably mounted on the rotating arm, and a linkage rod assembly is provided between the rotating arm and the upright brush. The linkage rod assembly includes connecting ears respectively provided on the upright brush and the rotating arm, and telescopic rods respectively provided on the connecting ears at both ends.

[0015] In some feasible embodiments, the system also includes a mounting rail disposed on the rotating arm and a matching grating assembly disposed on the mounting rail.

[0016] In some feasible embodiments, a spray assembly is also included on the rotating arm, the output end of the spray assembly facing the vertical brush, the spray assembly being used to deliver cleaning fluid to the vertical brush to wet the vertical brush.

[0017] To address the technical problems raised in this application, this application also provides a method for preventing jamming in an automatic side-washing device for vehicles, comprising the following steps: Obtain the conveying parameters of the vehicle to be washed, including the conveying speed of the conveying mechanism, the time the vehicle stays at the washing station, and the deflection angle of the vertical brush relative to the rotating arm. The vehicle to be washed is placed on the conveying mechanism, and it is determined whether the conveying speed of the conveying mechanism is lower than the first threshold; it is determined whether the dwell time of the vehicle to be washed at the brushing station is greater than the second threshold; it is determined whether the deflection angle of the vertical brush relative to the rotating arm is greater than the third threshold. If any of the above judgment results are yes, the control module controls the drive component to drive the rotating arm to rotate away from the vehicle to be washed to a preset safe avoidance position. If all the above judgment results are negative, continue to acquire the conveying parameters of the vehicle to be washed until any of the above judgment results are positive, and then control the drive component to drive the rotating arm to rotate to the preset safe avoidance position.

The anti-jamming mechanism includes a drive component and a damping buffer component, with the output end of the drive component and the movable end of the damping buffer component both located on the washing mechanism. By setting an anti-jamming mechanism between the support mechanism and the washing mechanism, when there is a risk of the vehicle getting stuck, the drive mechanism rotates away from the vehicle to avoid it. The damping buffer component enhances the smoothness of movement, effectively preventing excessive collisions and jamming between the vehicle and the washing device in case of equipment failure, preventing subsequent collisions, and improving car washing efficiency. It has the advantages of simple overall structure, easy operation, low implementation cost, reduced maintenance cost, improved user experience, and ease of promotion and implementation.

[0030] Combination Figures 1 to 11 The following content further illustrates the technical solution proposed in this application. This application adopts the following technical solution: an automatic anti-jamming washing device for the side of a vehicle, comprising a support mechanism X, a washing mechanism 1 rotatably disposed at one end of the support mechanism X, a washing station disposed between the support mechanism X and the washing mechanism 1, and an anti-jamming mechanism 2 disposed between the washing mechanism 1 and the support mechanism X. The anti-jamming mechanism 2 includes a drive assembly 20 disposed between the washing mechanism 1 and the support mechanism X, and a damping buffer assembly 21 disposed between the washing mechanism 1 and the support mechanism X. The output end of the drive assembly 20 is disposed on the washing mechanism 1, and the movable end of the damping buffer assembly 21 is disposed on the washing mechanism 1. When the vehicle to be washed is placed in the washing station, the drive assembly 20 can drive the washing mechanism 1 to rotate away from the vehicle to be washed. A method for preventing jamming in an automatic washing device for the side of a vehicle includes the following steps: Obtain the conveying parameters of the vehicle to be washed, including the conveying speed of the conveying mechanism, the time the vehicle stays at the washing station, and the deflection angle of the vertical brush relative to the rotating arm. The vehicle to be washed is placed on the conveying mechanism, and it is determined whether the conveying speed of the conveying mechanism is lower than the first threshold; it is determined whether the dwell time of the vehicle to be washed at the brushing station is greater than the second threshold; it is determined whether the deflection angle of the vertical brush relative to the rotating arm is greater than the third threshold. If any of the above judgment results are yes, the control module controls the drive component to drive the rotating arm to rotate away from the vehicle to be washed to a preset safe avoidance position. When the drive assembly drives the rotating arm to rotate, the damping buffer assembly simultaneously plays a buffering role, absorbing the instantaneous driving force and preventing the rotating arm from impacting and damaging the vehicle or equipment. If all the above judgment results are negative, continue to acquire the conveying parameters of the vehicle to be washed until any of the above judgment results are positive, and then control the drive component to drive the rotating arm to rotate to the preset safe avoidance position.

[0031] This application provides an automatic anti-jamming washing device and method for the side of vehicles. It includes a support mechanism, a washing mechanism rotatably mounted at one end of the support mechanism, a washing station located between the support mechanism and the washing mechanism, and an anti-jamming mechanism located between the washing mechanism and the support mechanism. The anti-jamming mechanism includes a drive component and a damping buffer component, with the output end of the drive component and the movable end of the damping buffer component both located on the washing mechanism. By setting an anti-jamming mechanism between the support mechanism and the washing mechanism, when there is a risk of the vehicle getting stuck, the drive mechanism rotates away from the vehicle to avoid it. The damping buffer component enhances the smoothness of movement, effectively preventing excessive collisions and jamming between the vehicle and the washing device in case of equipment failure, preventing subsequent collisions, and improving car washing efficiency. It has the advantages of simple overall structure, easy operation, low implementation cost, reduced maintenance cost, improved user experience, and ease of promotion and implementation.

[0032] In this embodiment, the brushing mechanism 1 includes at least two rotating arms 10 rotatably disposed at one end of the support mechanism X, and a vertical brush 11 disposed at the end of the rotating arm 10 away from the support mechanism X. The multiple rotating arms 10 and the multiple vertical brushes 11 together form the brushing station, and the anti-jamming mechanism 2 is disposed between the rotating arm 10 and the support mechanism X.

[0033] In actual implementation, after the equipment is started, the support mechanism X first completes positioning and fixation to ensure the stability of the overall structure. The brushing mechanism 1 enters the initial working state: two oppositely arranged rotating arms 10 are located in the preset working position, and the vertical brush 11 connected to the end away from the support mechanism X is simultaneously deployed. Multiple rotating arms 10 and vertical brush 11 together form a brushing station that conforms to the standard vehicle size (the station size can be adapted to most conventional vehicles, achieved through the initial angle positioning of the rotating arms). At this time, the anti-jamming mechanism 2 is in standby state: the drive component 20 (such as a pneumatic push rod) maintains the initial extension and retraction amount, and the damping buffer component 21 (such as a hydraulic damper, elastic damping sleeve, etc.) is in a natural extension and retraction state. The moving ends of both are firmly connected to the rotating arms 10 to ensure effective force transmission. The control module completes parameter initialization, presets the first threshold (lower limit of conveying speed), the second threshold (upper limit of dwell time), the third threshold (upper limit of rotation angle), and the safety avoidance position parameters, and connects with the conveying mechanism signal.

[0034] Furthermore, the first threshold is 50% of the normal operating speed of the conveying mechanism (e.g., 0.2 m / s), the second threshold is twice the time required for a vehicle to pass through the washing station (e.g., 60 s), and the third threshold is the maximum safe deflection angle of the vertical brush relative to the rotating arm (e.g., 15°); the preset safe avoidance position is a position where the distance between the vertical brush and the side of the vehicle to be washed is ≥10 cm.

[0035] The vehicle to be washed is transported to the entrance of the washing station via a conveyor mechanism (such as a conveyor belt). Simultaneously with the start of the conveyor mechanism, the control module triggers a parameter acquisition program to acquire three core conveying parameters in real time: ① the conveying speed of the conveyor mechanism (monitored by a speed sensor on the conveyor mechanism); ② the dwell time of the vehicle at the washing station (timed by photoelectric sensors at the station entrance / exit); ③ the deflection angle of the vertical brush 11 relative to the rotating arm 10 (monitored by a grating assembly installed at the connection between the vertical brush and the rotating arm; the deflection angle is positively correlated with the contact pressure, e.g., for every 1° increase in deflection angle, the contact pressure increases by 5N). After the vehicle has fully entered the washing station, the conveyor mechanism maintains a stable speed. Supported by the rotating arm 10, the vertical brush 11 contacts the side of the vehicle, achieving the washing operation on the side of the vehicle through its own rotation.

[0036] The control module (host computer, tablet, etc.) continuously analyzes the three collected parameters in real time to determine if there is a risk of jamming: ① If the conveying speed is lower than the first threshold, it indicates that the vehicle may stop moving due to a malfunction (such as jamming of the conveying mechanism or the vehicle's brakes not being released). In this case, the vertical brush continuously rubs against the side of the vehicle in a fixed position, which can easily cause jamming; ② If the vehicle's dwell time at the washing station is greater than the second threshold, even if the conveying speed is normal, it may become relatively stationary due to abnormal vehicle size or obstruction by foreign objects in the station, leading to jamming; ③ If the deflection angle of the vertical brush relative to the rotating arm is greater than the third threshold, it indicates that the lateral resistance experienced by the vertical brush exceeds the safe range (such as protrusions on the side of the vehicle or debris entangled in the vertical brush). Continuous force will cause the rotating arm to be unable to rotate normally, thus causing jamming. The control module uses "OR logic" for judgment; as long as any parameter triggers the threshold, it is determined that there is a risk of jamming.

[0037] When a risk of jamming is detected, the control module immediately sends a drive signal to the drive component 20 of the anti-jamming mechanism 2. The output of the drive component 20 generates a driving force, causing the rotating arm 10 to rotate around its connection point with the support mechanism X in a direction away from the vehicle to be washed (i.e., expanding the brushing station space). During this process, the damping buffer component 21 works simultaneously: on the one hand, it absorbs the instantaneous driving force of the drive component 20 through its own damping characteristics, avoiding the impact caused by the rapid rotation of the rotating arm 10 (preventing impact damage to the side of the vehicle or the equipment structure); on the other hand, it buffers the vibration during the rotation of the rotating arm 10, ensuring smooth rotation. The rotating arm 10 drives the vertical brush 11 to move away from the vehicle simultaneously until it reaches the preset safe avoidance position (this position ensures that the vertical brush is completely out of contact with the vehicle, eliminating the risk of jamming). The drive component 20 stops working, and the damping buffer component 21 maintains its current extension and retraction state, keeping the avoidance position of the rotating arm 10 stable.

[0038] If none of the parameters trigger the threshold (no risk of jamming), the control module continues to monitor the parameters, the brushing mechanism 1 maintains its initial working state, and the vertical brush 11 continues to rotate and brush until the vehicle completely passes through the brushing station, completing the side cleaning. If the avoidance has been triggered, after the control module detects that the risk of jamming has been eliminated (such as the conveying speed returning to normal, the dwell time no longer exceeding the standard, and the vertical brush angle returning to the safe range), the drive component 20 reverses the drive, causing the rotating arm 10 to reset to the initial working position, and the damping buffer component 21 resets synchronously. The equipment returns to the normal brushing state, waiting for the next vehicle to be washed to enter.

[0039] In actual implementation, this solution adopts a "multi-parameter collaborative monitoring" mode, covering three types of jamming risk sources: conveying speed, residence time, and contact pressure (indirectly reflected by angle). This avoids misjudgments or omissions caused by monitoring a single parameter (such as failing to identify jamming caused by abnormal vehicle size when only speed is monitored). At the same time, the anti-jamming mechanism 2, through the cooperation of the drive component and the damping buffer component, ensures both rapid response of the avoidance action (active force exerted by the drive component) and avoids impact damage during the avoidance process (impact reduction by the damping component). This effectively solves the technical problems of "stopping immediately upon jamming" and "easy collision upon jamming" in traditional washing equipment, reducing the probability of equipment failure and vehicle maintenance costs.

[0040] In this embodiment, the brushing mechanism 1 further includes an angle adjustment mechanism 3 disposed between the rotating arm 10 and the support mechanism X. The angle adjustment mechanism 3 is used to adjust the tilt angle of the rotating arm 10 relative to the support mechanism X in the vertical direction.

[0041] In this embodiment, the angle adjustment mechanism 3 includes a plurality of adjustment holes 30 disposed at one end of the rotating arm 10 near the support mechanism X, an adjustment column 31 disposed on the support mechanism X at the corresponding position of the adjustment holes 30, and a fastener disposed on the adjustment column 31. The cross-sectional shape of the adjustment hole 30 is racetrack-shaped, and the plurality of adjustment holes 30 are spaced apart around the center of the rotating arm 10.

[0042] In actual implementation, the angle adjustment mechanism 3 operates as follows: The rotating arm 10, near the support mechanism X, has multiple racetrack-shaped adjustment holes 30 spaced around its center. The support mechanism X has a corresponding adjustment post 31. The operator pushes the rotating arm 10, causing the adjustment post 31 to slide within the adjustment hole 30 at the target position (the racetrack-shaped holes provide travel space for tilt adjustment). When the tilt angle of the rotating arm 10 reaches the preset value for the vehicle model, the adjustment hole 30 and the adjustment post 31 are secured and locked by fasteners (such as lock nuts) on the adjustment post 31, completing the angle positioning. This stage ensures that the vertical brush 11 can form the optimal contact angle with the side of the vehicle, laying the foundation for subsequent cleaning effectiveness.

[0043] In actual implementation, by adjusting the vertical tilt angle of the rotating arm, it can precisely adapt to vehicles with different body heights (such as microcars, SUVs, and mid-to-large sedans) and different side curvatures (such as fastback models and boxy models), solving the problems of the original fixed-angle rotating arm being unable to adapt to irregularly shaped vehicles and the vertical brush not adhering tightly to the vehicle body during cleaning. The design of the racetrack-shaped adjustment hole 30 provides continuous stroke space for angle adjustment. Combined with multiple intervald adjustment holes, it can achieve precise adjustment in multiple levels and small steps, meeting the personalized adaptation needs of different vehicle models.

[0044] Furthermore, the contact angle between the vertical brush and the side of the vehicle directly affects the cleaning effect. The angle adjustment mechanism allows the vertical brush to always contact the side of the vehicle at the optimal angle. Whether it is a raised part such as the waistline of the body and the area near the wheel arch, or a recessed part such as the area below the door, it can effectively clean the area. This avoids the problem of dead corner residue caused by the "sweeping" cleaning of the vertical brush under the original fixed angle, and improves the uniformity and thoroughness of cleaning.

[0045] In this embodiment, the brushing mechanism 1 further includes limiting components 4 disposed on both sides of the rotating arm 10, the limiting components 4 being used to limit the rotation angle of the rotating arm 10 relative to the support mechanism X.

[0046] In this embodiment, the limiting component 4 includes limiting seats 40 disposed on both sides of the rotating arm 10, limiting posts 41 disposed on the limiting seats 40, and buffer blocks 42 disposed on the limiting posts 41 near one end of the rotating arm 10. When the rotating arm 10 rotates relative to the support mechanism X, the buffer blocks 42 can abut against the side of the rotating arm 10 to limit the rotation angle of the rotating arm 10.

[0047] In this embodiment, a boss 5 is also provided between any of the rotating arms 10 and the support mechanism X, the boss 5 being used to stagger the arrangement of two adjacent rotating arms 10.

[0048] In actual implementation, the thickness and installation position of the boss 5 are designed to create an interleaved arrangement between adjacent rotating arms 10 (i.e., adjacent rotating arms 10 have a height difference in the horizontal direction and are not coplanar). The core purpose of this interleaved layout is to avoid structural interference between adjacent rotating arms 10 during rotation, and to provide a basis for the subsequent interleaved brushing of the vertical brush 11. After assembly, the interleaved gaps of each rotating arm 10 are checked to ensure there is no risk of collision. The connection between the boss 5 and the rotating arms 10 and the support mechanism X is secured with bolts to ensure structural stability.

[0049] In this embodiment, the upright brush 11 is rotatably mounted on the rotating arm 10, and a linkage rod group 6 is provided between the rotating arm 10 and the upright brush 11. The linkage rod group 6 includes connecting ears 60 respectively provided on the upright brush 11 and the rotating arm 10, and telescopic rods 61 with both ends respectively provided on the connecting ears 60.

[0050] In this embodiment, the mounting rail 7 is provided on the rotating arm 10, and the grating assembly 8 is matched and provided on the mounting rail 7.

[0051] In this embodiment, a spray assembly 9 is also provided on the rotating arm 10. The output end of the spray assembly 9 faces the vertical brush 11. The spray assembly 9 is used to deliver cleaning fluid to the vertical brush 11 to wet the vertical brush 11.

[0052] In actual implementation, during equipment assembly, precise installation and debugging of each newly added component are required: ① Linkage rod group 6: Fix two sets of connecting ears 60 to the rotating shaft of the vertical brush 11 and the rotating arm 10 respectively; the two ends of the telescopic rod 61 are hinged to the connecting ears 60 through pins to ensure that it can extend and retract flexibly; through the extension and retraction of the telescopic rod 61, the vertical brush 11 is driven to swing around the mounting shaft of the rotating arm 10; ② Grating assembly 8: Fix the mounting guide rail 7 along the length of the rotating arm 10, install the grating transmitter and receiver at both ends of the guide rail respectively, arrange the grating ruler against the guide rail, connect the grating reading head to the sliding part (or vertical brush mounting seat) on the rotating arm 10, and debug the signal transmission of the grating assembly 8 to ensure that the position information of the vertical brush 11 can be accurately collected; ③ Spray assembly 9: Fix the spray pipe and nozzle to the rotating arm 10, ensuring that the output end of the nozzle faces the bristle area of ​​the vertical brush 11, connect the cleaning fluid delivery pipeline and the booster pump, and debug the spray range and pressure of the nozzle to ensure that the cleaning fluid can evenly cover the vertical brush 11. Meanwhile, the boss 5 maintains the staggered layout of adjacent rotating arms 10, and the limiting component 4 presets the limit rotation angle of the rotating arm 10.

[0053] In actual implementation, the linkage assembly 6, through the coordinated extension and retraction of the telescopic rod 61 and the rotation of the connecting ear 60, drives the vertical brush 11 to swing flexibly, adaptively conforming to the concave and convex contours of the car body side (such as waistline, wheel arch, and around door handles), solving the problem that traditional fixed-post vertical brushes cannot accurately conform to irregularly shaped parts, ensuring thorough cleaning without blind spots. The flexible linkage structure of the linkage assembly can buffer the contact pressure between the vertical brush 11 and the car body, avoiding paint scratches caused by rigid contact, while also reducing excessive wear on the bristles and extending the service life of the vertical brush; the extension and retraction stroke of the telescopic rod 61 can limit the maximum swing angle of the vertical brush, preventing loss of posture control. The grating assembly 8, through the grating ruler on the mounting rail 7 and the reading head, can collect the position data of the vertical brush 11 in real time, providing precise vertical brush posture feedback to the control module; if the vertical brush position exceeds the preset range, it can be judged as abnormal in advance (such as bristle entanglement, vertical brush deviation), assisting the anti-jamming mechanism to act in advance, improving the accuracy of risk prediction.

[0054] This application provides an automatic anti-jamming washing device and method for the side of vehicles. It includes a support mechanism, a washing mechanism rotatably mounted at one end of the support mechanism, a washing station located between the support mechanism and the washing mechanism, and an anti-jamming mechanism located between the washing mechanism and the support mechanism. The anti-jamming mechanism includes a drive component and a damping buffer component, with the output end of the drive component and the movable end of the damping buffer component both located on the washing mechanism. By setting an anti-jamming mechanism between the support mechanism and the washing mechanism, when there is a risk of the vehicle getting stuck, the drive mechanism rotates away from the vehicle to avoid it. The damping buffer component enhances the smoothness of movement, effectively preventing excessive collisions and jamming between the vehicle and the washing device in case of equipment failure, preventing subsequent collisions, and improving car washing efficiency. It has the advantages of simple overall structure, easy operation, low implementation cost, reduced maintenance cost, improved user experience, and ease of promotion and implementation.

10. A method for preventing jamming in an automatic washing device for the side of a vehicle according to any one of claims 1-9, comprising the following steps: Obtain the conveying parameters of the vehicle to be washed, including the conveying speed of the conveying mechanism, the time the vehicle stays at the washing station, and the deflection angle of the vertical brush relative to the rotating arm. Place the vehicle to be washed on the conveyor mechanism and determine whether the conveying speed of the conveyor mechanism is lower than the first threshold; determine whether the dwell time of the vehicle to be washed at the washing station is greater than the second threshold. Determine whether the deflection angle of the vertical brush relative to the rotating arm is greater than the third threshold. If any of the above judgment results are yes, the control module controls the drive component to drive the rotating arm to rotate away from the vehicle to be washed to a preset safe avoidance position. If all the above judgment results are negative, continue to acquire the conveying parameters of the vehicle to be washed until any of the above judgment results are positive, and then control the drive component to drive the rotating arm to rotate to the preset safe avoidance position.
