Embodiment Construction

[0006] The wiper is driven by a motor, and the rotary motion of the motor is converted into the reciprocating motion of the scraping arm through a four-bar linkage mechanism, thereby realizing the wiper action. Generally, when the motor is turned on, press the wiper working switch to make the wiper work. By selecting high-speed and low-speed gears, there are three gears: low speed, high speed, and intermittent, which can change the current of the motor to control the speed of the motor, thereby controlling the working speed of the wiper. The wiper assembly includes motor, reducer, four-bar linkage, wiper arm spindle, wiper blade assembly, etc. When the switch of the wiper is pressed, the motor starts, the speed of the motor drives the swing arm through the deceleration and torque increase of the worm gear, the swing arm drives the four-bar linkage mechanism, the four-bar linkage mechanism drives the shaft to swing left and right, and finally the shaft drives the wiper blade S...
