[Branden]

The method to turn off the rear wiper of the car: There is a switch on the car's wiper lever; you can change different gears by toggling it. The default state of the knob is at the "O" position at the bottom, which is the gear to turn off the rear wiper. Adjusting the knob to the middle position turns on the rear wiper. The wiper is a tool installed on the front windshield of motor vehicles to simply clean rainwater and other debris that may obstruct vision. The power source of the wiper comes from an electric motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives a four-bar linkage mechanism, which converts continuous rotational motion into a left-right oscillating motion.
