Basic structure of a windshield wiper
The electric windshield wiper is driven by a motor and typically consists of components such as the wiper arm, the wiper blade assembly, rubber wiper blades, blade holders, blade supports, the wiper arm spindle, the wiper baseplate, the electric motor, the reduction mechanism, the drive rod assembly, the drive rod hinges, the wiper switch, and the wiper switch knob. Of course, wipers equipped with a wiper ECU also feature an electronic control unit (ECU). The electric windshield wiper is driven by an electric motor; the left and right wiper blades are pressed against the outer surface of the windshield by the wiper arm. The motor rotates the reduction mechanism, which in turn drives the drive rod system to perform reciprocating motion, causing the wiper arm and blades to swing from side to side and effectively wipe the windshield.
