The manufacturer introduces the main composition and use of car wipers

Cars are currently a common means of transportation in cities. Due to some national policies, the number of vehicles in cities has greatly increased, which has increased the sales and production of car wipers. When it rains, it is inevitable to use the car's boneless wiper to remove rainwater on the front glass of the car to prevent blurred vision.

The wiper assembly includes a wiper motor, a reducer, a four-link mechanism, a wiper arm spindle, a wiper blade, etc. When the driver presses the switch of the wiper, the motor starts. The speed of the motor drives the swing arm through the deceleration and torsion increase of the worm gear. The swing arm drives the four-link mechanism, which drives the shaft mounted on the front wall to swing left and right. , The wiper blade is driven by the shaft to sweep the windshield.

The power source of the wiper comes from the electric motor, which is the core of the entire wiper system. The quality requirements of wiper motors are quite high. 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 decelerate and increase the torsion, and its output shaft drives the four-bar linkage mechanism, through which the continuous rotary motion is changed to the left and right swing motion.

The wiper motor adopts a 3-brush structure to facilitate speed change. The intermittent time is controlled by an intermittent relay, and the charge and discharge functions of the return switch contact of the motor and the resistance and capacitance of the relay are used to make the wiper wipe according to a certain period. The wiper blade rubber strip is a tool to directly remove rain and dirt on the glass. The wiper strip is pressed against the glass surface by the spring strip, and its lip must match the angle of the glass in order to achieve the required performance.

All in all, car wiper is an indispensable appliance for cars. The development of wiper is very fast. At present, it is not only used in cars, but other vehicles have similar devices to remove rainwater in rainy days.
