A speed controller 430 is provided on the top of the caster arm 200. The speed controller 430 is located on the side of the driving mechanism 400. The speed controller 430 is electrically connected to the driving mechanism 400 and the pressure sensor 420, and is used to control the rotation speed and output force of the driving mechanism 400. When the force value signal of any one or more of the pressure sensors 420 is lower than the preset force threshold signal, the pressure sensor 420 sends an opening signal to the speed controller 430, so that the speed controller 430 controls the opening speed of the driving mechanism 400, which can quickly respond to load changes and adjust the force applied to the ground by the lower surface of the balancing wheel 300, thereby realizing automatic adjustment to maintain the balance and stability of the car washing machine.

When the motor 411 rotates, it drives the piston 412 to move linearly, thereby pushing the driving mechanism 413 to slide toward the surface of the balancing wheel 300, and adjusting the force value between the balancing wheel 300 and the ground to balance the forces of the four balancing wheels 300, so as to achieve automatic adjustment to maintain the balance and stability of the car washing machine, so that the automatic balancing wheel 300 system can remain stable under different load conditions, reduce the unstable operation on the inclined ground, improve the stability and reliability of the car washing machine on the inclined ground, and enhance the user's sense of security.

The embodiment of the present application discloses a method for controlling an automatic balancing wheel for a self-service car washing machine. Referring to FIG. 4 , a method for controlling an automatic balancing wheel 300 for a self-service car washing machine includes: using a fault detection system to detect the operating state of a tilt sensor 500. If the fault detection system detects that the tilt sensor 500 is abnormal, the current abnormal information is obtained and sent to a pre-bound maintenance personnel terminal, and an alarm instruction is triggered to prompt the user that there is a problem with the current self-service car washing machine;

When the force value signal of any one or more of the pressure sensors 420 is lower than the preset force threshold signal, the control system 110 sends a start instruction to the speed controller 430 and the drive mechanism 400. When the speed controller 430 receives the start instruction, it receives a speed instruction from the drive mechanism 400 located on the caster arm 200 to control the operating speed of the drive mechanism 400, so that the drive mechanism 400 drives the force mechanism 413 to apply pressure to the balancing wheel 300 where the pressure sensor 420 is installed.

If an abnormality is detected in the tilt sensor 500, the fault detection system will obtain the current abnormality information and send it to a pre-bound maintenance personnel terminal. At the same time, the fault detection system will trigger an alarm command to remind the user with a sound or visual signal that there is a problem with the current self-service car washing machine. When the fault detection system detects normally, the tilt sensor 500 obtains the detected tilt angle signal, and the tilt angle signal will be sent to the control system 110. The control system 110 sends a gravity detection command to the pressure sensor 420, and uses the pressure sensor 420 to detect the force value between the currently tilted balancing wheel 300 and the ground. A quantitative force is applied. When the force value signal of any one or more of the pressure sensors 420 is lower than the preset force threshold signal, the control system 110 sends a start instruction to the speed controller 430 and the drive mechanism 400. When the speed controller 430 receives the start instruction, it receives a speed instruction from the drive mechanism 400 located on the caster arm 200 to control the operating speed of the drive mechanism 400, so that the motor 411 drives the piston 412 and the driving mechanism 413 to move, so that the driving mechanism 413 presses against the balance wheel 300, increases the quantitative force to perform adaptive balance control on the balance wheel 300, realizes real-time monitoring and automatic adjustment of the system, so as to maintain the balance and stability of the car washing machine, thereby improving the user experience and increasing the user satisfaction with the self-service car washing service.

The automatic balancing wheel system for a self-service car washing machine according to claim 1, characterized in that: A tilt sensor (500) is provided at the center of gravity of the bottom of the car washing machine body (100), and the tilt sensor (500) is used to detect the tilt angle of the car washing machine body (100). A fault detection system is provided on the tilt sensor (500), and the fault detection system is used to detect the operating state of the tilt sensor (500). The tilt sensor (500) is electrically connected to the control system (110); The tilt sensor (500) is provided with an angle threshold signal. When the tilt sensor (500) detects that the tilt angle signal of the car washing machine body (100) is greater than the angle threshold signal, the tilt sensor (500) sends a start signal to the control system (110). 8. A method for controlling an automatic balancing wheel for a self-service car washing machine, characterized in that: The operating state of the tilt sensor (500) is detected by using a fault detection system. If the fault detection system detects that the tilt sensor (500) is abnormal, current abnormal information is obtained and sent to a pre-bound maintenance personnel terminal, and an alarm instruction is triggered to prompt the user that there is a problem with the current self-service car washing machine; When the fault detection system detects normally, the tilt angle signal detected by the tilt sensor (500) is obtained, and when the tilt sensor (500) detects that the tilt angle signal of the car washing machine body (100) is greater than the angle threshold signal, the tilt sensor (500) sends a start signal to the control system (110); The control system (110) sends a start signal to the pressure sensor (420). The control system (110) is electrically connected to the pressure sensor (420), the drive mechanism (400) and the speed controller (430). The pressure sensor (420) is used to detect the force value between the current balance wheel (300) and the ground. When the force value signal of any one or more pressure sensors (420) among the plurality of pressure sensors (420) is lower than a preset force threshold signal, the control system (110) sends a start instruction to the speed controller (430) and the drive mechanism (400). When the speed controller (430) receives the start instruction, it sends a speed instruction to the drive mechanism (400) located on the caster arm (200) to control the operating speed of the drive mechanism (400), so that the drive mechanism (400) drives the force mechanism (413) to apply pressure to the balance wheel (300) at the installation location of the pressure sensor (420).
