Also comprise the scrubber in fixing operator's compartment, be connected with water pipe on scrubber, water pipe is connected on the water jet being arranged on outside operator's compartment.
Described controller is connected with motor by wire harness.
Described motor is as power resources, and motor gear moves in a circle, and drives quadric linkage to do return motion.
Described motor internal is provided with when motor moves to reset position and forms and open circuit, and makes motor out-of-work ' C ' type contact disk.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is by the car body at front windshield downside, rain brush being installed, and using motor as propulsion source, the motion of driving rain brush, controls rain brush by controller simultaneously and do high speed, low speed, reset and intermittent moment; The utility model propulsion source is power supply, because electric current and voltage fluctuation is little, so the wiper frequency stabilization of rain brush, and adopt behind electronic source, make whole device volume little, simple in structure, cheap, easy to maintenance, actv. has been saved cost installing space.
Further, the utility model is at motor internal setting ' C ' type contact disk, and when motor moves to reset position, formation is opened circuit, and motor quits work, and without hand reset, windshield wiper automatically resets to initial position.
