Car elevator switch principle
The car lift switch is an electric switch used to control the lifting function of the car's window or roof. Its working principle is mainly composed of the following parts: motor, switch, relay and control module.
1. Motor: The car elevator switch realizes the lifting of the window or roof by controlling the forward and reverse of the motor. The motor is usually powered by a DC power source, turning forward to open the window or roof, and turning backward to close the window or roof.
2. Switch: The switch is the trigger device that operates the function of the car elevator. When the user presses the button on the switch, the switch will send the corresponding signal to the control module, thus controlling the direction and speed of the motor.
3.Relay: Relay is a kind of electromagnetic switch, used to control the large current on and off. In automotive elevator switches, relays are usually used to provide high-power current from the power supply to the motor to ensure that the motor can operate normally.
4. Control module: The control module is the main control unit of the car elevator switch, which is responsible for receiving the signal sent by the switch and controlling the motor movement. The control module passes
The signal of the break switch is used to determine the working state of the motor, and the speed and lifting position of the motor can be adjusted. When the user presses the button on the car elevator switch, the switch will send a signal to the control module. After receiving the signal, the control module switches the forward and reverse rotation of the motor through the control relay. When the motor starts to rotate, the function of lifting and lowering is realized through a slide or zipper mechanism connected to the window or roof of the car.
In general, the car elevator switch uses the motor, switch, relay and control module to work with each other, and realizes the lifting function of the car window or roof through the positive and reverse of the motor.
Car lifting switch is broken how to repair
The method of repairing the automobile lift switch mainly includes checking and replacing the switch, cleaning the mud tank or rubber strip, refixing the screw, replacing the elevator, and reinstalling the guide rail.
Check and replace the switch: First, check whether the lift switch is damaged. If the switch is damaged, replace it with a new one. This is the most direct and common repair method.
Clean the mud tank or rubber strip: If the mud tank or rubber strip has foreign objects, deformation or damage, it also needs to be replaced. Keeping these components clean and intact is essential to ensure the proper functioning of the lift switch.
Refix the screw: If the lifter fixing screw is loose, you need to refix the screw. This ensures that the lifter can work stably and avoid failure due to loosening.
Replace with new lifter: If the glass lifter itself is damaged, a new lifter needs to be replaced. This may require professional tools and skills, and it is recommended to go to a professional repair shop for replacement.
Reinstall the guide rail: If the guide rail is installed in a wrong position, reinstall it. This involves adjusting the position of the guide rails to ensure that they can properly guide the lifting and lowering of the glass.
Other possible repair methods include checking the circuit diagram, removing debris, checking the aging or short circuit of the window lifter, and replacing the lifter itself. These methods may involve more complex repair work, such as circuit inspections and replacement of electronic parts.
It should be noted that there may be many reasons for the failure of the door glass, and it needs to be carefully investigated. During the repair process, if you encounter difficulties or uncertainties, it is recommended to seek the help of professionals to avoid causing greater damage.
