What is the principle of the wiper?

The principle of the wiper is driven by a motor, which converts the rotational motion of the motor into the reciprocating motion of the wiper arm through a linkage mechanism, thereby achieving the wiping action. Here are some precautions for using the wiper: 1. Maintain hygiene: When there are streak marks on the glass surface, the wiper blade may be dirty. You can sprinkle alcohol on a towel and wipe the surface of the wiper blade. Cleaning once a month can improve the working efficiency of the wiper. 2. Check the rubber: If the wiper makes abnormal noises during operation, the rubber blade may be aged or cracked. If the wear is not severe, you can use sandpaper to smooth out rough spots on the surface. 3. Avoid sunlight: Park the car in a shady place where it is not exposed to the sun, such as a garage. Summer is a season that is particularly harsh on cars. Wiper blades are rubber products, and exposure to sunlight will only accelerate the aging process.
I've driven many cars before, and the principle of the wiper mainly relies on a small motor to drive it. When you press the switch, the motor starts rotating, and then through a linkage, the rotational force is converted into a left-right swinging motion, allowing the wiper arm with the rubber blade to sweep back and forth on the windshield to remove rain or dirt. The design is ingenious, simple, and efficient, but the key is that it has different speed settings, such as a low-speed setting for light rain and a high-speed setting for heavy rain, to prevent blurred vision while driving. I've also found that regularly checking the wiper blades is crucial because when the rubber deteriorates, it can leave water streaks, so they must be replaced in time to avoid accidents. Driving in the rain relies entirely on them, so I think although they're small, they're vital for safety.
