The windshield wipers of an automobile mainly consist of core components such as wiper arms, wiper blades, wiper motors, transmission mechanisms, and connecting rods. Among them, the rubber strip that directly contacts the glass is called a wiper blade (or squeegee), which is fixed on the wiper arm through a metal bracket or elastic structure and is responsible for removing rainwater and debris. The wiper motor provides power, which is converted into the reciprocating swing of the wiper arm through a speed reducer and a four-bar linkage mechanism, ensuring that the wiping range covers the windshield. It is generally recommended to replace them every 12 months to maintain optimal performance. Additionally, avoid dry wiping or using the wipers directly to clean stubborn dirt, as this may damage the rubber strip. Furthermore, using windshield washer fluid can enhance cleaning effectiveness and prolong the service life of the wiper blades.
