What is a wiper blade and how it works

Wiper blades generally refer to wipers, which are important accessories installed on the windshield. Its role is to remove rain, snow and dust from the windshield, giving the driver a clear and open view. Driving safety is very important for drivers. Wiper blades can reduce the rate of traffic accidents and ensure people’s travel safety. Therefore, it plays an important role in driving safety. Wipers generally include vacuum wipers, electric wipers, and wipers with electronic control units. The downside of wiper vacuums is that the wiper blades move at a erratic speed. When the engine’s vacuum level is reduced (such as when the car is climbing a hill), the wiper blades stop and the driver’s vision is blurred. Vacuum wipers were phased out in 1972, replaced by electric wipers. Working principle: The motor on the electric wiper drives the output shaft through the worm gear on the armature shaft, drives the output gear through the idler gear and the idler gear shaft, and then the output shaft controls the output arm connected to the wiper connecting rod. When the motor rotates, it drives the output arm and link to move back and forth. The resistance on the control switch is connected with the armature winding of the motor to control the speed of the motor, and the driver can toggle the switch as needed to make the current flow into the input circuit of the motor. Replacement frequency: generally about a year, mainly depends on the frequency of use. Also, remember to wipe the wiper blades with a towel every time it rains, which not only increases the service life but also protects the glass.
