What is the working principle of the New Santana wiper?

[Simoes]

The power source of the wiper comes from the motor, which is the core of the entire wiper system. Main principle: The wiper has quite high quality requirements for the motor. It adopts 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, and its output shaft drives the four-bar linkage mechanism, which converts continuous rotational motion into left-right swinging motion. Extension: 1. Wiper control system: Through the electronic control system, not only can the delay control of the wiper be achieved, but also some other complex controls. 2. The electronic control system includes a dual-speed motor and two limit switches. The following functions can be achieved through a handle switch: washing, wiping, high-speed wiping, low-speed wiping, intermittent wiping, and delay control. More complex electronic control systems can also achieve swing adjustment pressure control and rain-sensing control.
