The original windshield wipers were operated by moving the internal levers of the car back and forth by hand. Nowadays, when it comes to windshield wipers, most people think of electric windshield wipers. The wipers keep the windows clean by constantly moving back and forth across the windshield to remove stagnant water. When the speed of the wiper reaches value, its power is amazing, and sometimes even drive the car to swing left and right. What is the mechanism that makes the wiper rocker move so magically? Windshield wipers can be found on car windshields, some car headlights, airplanes and even spaceships.
The wiper combines two mechanical techniques: one is powered by an electric motor and a decelerating worm wheel. Second, through the linkage mechanism to drive the motor wiper.
It takes a lot of power for the motor and the gear to move the wipers up and down the windshield at high speed. To generate this power, the designers used a worm wheel at the output end of a small motor. Worm reduction gear can increase the torque of the motor by about 50 times, while reducing the output speed of the motor by 50 times. The power output from the reduction gear operates the linkage mechanism to move the wiper back and forth. Inside the motor/gear assembly is a circuit that can sense the understop of the wiper. The circuit supplies power to the wiper, which cuts off the motor when it stops at the bottom of the windshield. The circuit can also be intermittently set according to the wiper, so that the wiper is temporarily paused in the wiper process. A short camshaft is connected with the output shaft of the reduction gear of the linkage mechanism. The camshaft rotates with the rotation of the wiper motor. The camshaft is connected to a long rod; when the camshaft rotates, it drives the rod back and forth. The long pole is connected to a short pole which drives the driver's side wiper. Another long pole transfers power from the driver's side to the passenger's side.
Control the windshield wiper to keep the windshield clear on rainy and snowy days. Household cars use electric wipers, the switch is located on the steering column side of the wiper combination handle, fast, slow, stop three positions. Cleaning fluid nozzle button switch-spray cleaning fluid to the glass, generally located in the end of the wiper combination handle, press once to spray a cleaning fluid to the glass
