Car wiper structure and the importance of wiper motor

The car wiper is one of the important parts of the car. Its function is to scrape off water droplets, dust, snow and other debris on the glass through the wiper blade on rainy days or other situations where the windshield needs to be cleaned, ensuring that the driver The vision is clear.

The structure of a car wiper consists of five main components: motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly.

1. The electric motor is the core component that drives the wiper. It is powered by the battery and converts electrical energy into mechanical energy, which determines the power performance and life of the wiper.

2. The reducer converts the high-speed rotation of the motor into the low-speed rotation of the wiper arm. It also plays the role of transmitting torque and adjusting the movement range of the wiper arm.

3. The four-bar linkage mechanism converts the rotation direction of the wiper arm into a linear direction, allowing the wiper blade to swing back and forth on the windshield.

4. The wiper arm spindle is a component that connects the wiper arm and the four-bar linkage mechanism. It can rotate within a certain angle to adapt to different shapes of windshields.

5. The wiper blade assembly is a component used to clean rainwater on the windshield. It consists of a rubber wiper blade and a metal frame. The rubber wiper blade fits the glass surface, and the metal frame provides support and elasticity.
