Press the wiper controller located next to the steering wheel to turn it off. Below is additional information about wipers: 1. Basic Introduction: The wiper is a tool installed on the front windshield of motor vehicles to prevent rain and other debris from obstructing the driver's view. The wiper assembly includes components such as the motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. When the driver activates the wiper switch, the motor starts. The motor's speed, after being decelerated and torque-increased by the worm gear mechanism, drives the swing arm. The swing arm then moves the four-bar linkage, which in turn causes the shaft mounted on the front panel to oscillate left and right, ultimately driving the wiper blade to sweep across the windshield. 2. Working Principle: The power source of the wiper comes from the motor, which is the core of the entire wiper system. The motor's quality requirements are quite high, typically using a DC permanent magnet motor. The wiper motor installed on the front windshield is usually integrated with the worm gear mechanism. The worm gear mechanism serves to reduce speed and increase torque, with its output shaft driving the four-bar linkage. This converts continuous rotational motion into oscillating motion. The motor's return switch contacts, combined with the relay's resistor-capacitor charging and discharging functions, enable the wiper to sweep at regular intervals.
