How to Use the Car Wiper Switch?

[Kyle]

The method to use the wiper is to push the wiper control upward for an automatic return, which activates the wiper once, while downward it is divided into three gears. Below is relevant information about car wipers: 1. Basic Introduction: The wiper, also known as a windscreen wiper, is a device used to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. Due to legal requirements, almost all cars are equipped with wipers. Rear windows of vehicles such as hatchbacks and SUVs also have wipers. Apart from cars, other means of transportation like trains and trams are also equipped with wipers. Some engineering machinery, such as cranes, also have wipers installed. 2. Operating Principle: The power source of the wiper comes from an electric motor, which is the core of the entire wiper system. 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, and its output shaft drives a four-bar linkage mechanism, which converts continuous rotational motion into left-right swinging motion.
