Description

Technical Field

[0001] The utility model relates to a special vehicle appliance, in particular to a windshield wiper. Background Art

[0002] Electric windshield wipers are driven by an electric motor and generally consist of a wiper arm, wiper blade assembly, rubber wiper blade, wiper blade holder, wiper blade support, wiper arm spindle, wiper base plate, motor, reduction gear, drive lever system, drive lever hinge, wiper switch, and wiper switch knob. Wiper systems equipped with a wiper ECU also include an electronic control unit (ECU). Electric windshield wipers are driven by an electric motor. The left and right wiper blades are pressed against the windshield surface by the wiper arms. The motor rotates the reduction gear, which, through the drive lever system, causes the wiper arms and wiper blades to swing left and right, wiping the windshield. The electric motor in an electric wiper drives the output shaft via a worm gear on the armature shaft, which in turn drives the output gear via an idler gear and idler shaft. The output shaft then operates the output arm connected to the wiper connecting rod. Rotation of the motor drives the output arm and connecting rod, moving them forward and backward. The resistor on the control switch is connected to the armature winding of the motor to control the speed of the motor. The driver can flip the switch as needed to allow current to flow into the input circuit of the motor.

[0003] However, for special vehicles, which usually travel on special muddy roads and experience large vibrations and bumps during travel, existing wipers are prone to malfunction or damage. Therefore, there is a need for a wiper with high stability and durability to solve this technical problem. Utility Model Content
