Wiper blade

Wiper blades are commonly used body accessories for automobiles. They are mainly used to wipe off rainwater on the windshield in rainy weather, and are also used to wash the windshield. The power source of the wiper blade comes from the electric motor, which is the core of the entire wiper blade system.

PRODUCT DETAILS

Wipers generally include vacuum wipers, electric wipers, and wipers with electronic control units. The disadvantage of the vacuum wiper is that the moving speed of the wiper blade is unstable. When the vacuum of the engine is reduced (for example, when the car is climbing a slope), the wiper blade will stop and blur the driver's vision. Vacuum wipers were eliminated in 1972, replaced by electric wipers.

The electric motor on the electric wiper drives the output shaft through the worm gear on the armature shaft and drives the output gear through the idler gear and the idler shaft, and then the output arm connected to the wiper link is manipulated by the output shaft. When the motor rotates, the output arm and connecting rod are driven to move forward and backward.

The resistor on the control switch is connected with the armature winding of the motor to control the speed of the motor. The driver can pull the switch as needed to make current flow into the input circuit of the motor.
