The wiper arm converts the rotational motion of the motor into the reciprocating swing of the wiper blade through its connection with the wiper motor. The power of the motor is transmitted to the wiper blade through the lever structure of the wiper blade, allowing it to clean the windshield at a set speed and angle.
2. Support wiper blades
The wiper arm provides stable support for the wiper blades, ensuring that they can maintain good contact with the windshield during the swinging process. It is usually made of sturdy metal materials that can withstand certain pressure and vibration, and the brush blade can work normally under various working conditions.
