Wiper mounting plate frame  

Overview of wipers: A wiper is a tool for simply cleaning the front glass of a motor vehicle to prevent rainwater and other dirt from affecting the view. Operating principle: The power source of the wiper comes from the electric motor, which is the core of the entire wiper system. The quality requirements of wiper motors are quite high. It uses a DC permanent magnet motor. 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 the four-bar linkage mechanism, and the continuous rotational motion is changed into a left-right swing motion through the four-bar linkage mechanism. The wiper motor adopts a 3-brush structure to facilitate speed changes. The intermittent time is controlled by the intermittent relay. The return switch contact of the motor and the charge and discharge function of the relay's resistance an…
