Abstract
The utility model pertains to a cleaning device for a vehicle, in particular a vehicle windshield wiper, with the purpose of mainly solving the problems of reducing the power for the wiper, synchronizing the two wipers, and reducing the size of the motor and the cost. The main technical characteristics of the utility model are that a soft shaft is arranged between two motors to realize the forced synchronization of the two wipers, and the reducing devices of the motors are used to drive the cranks, the rocking arms and the swing stems respectively, and further propel the two wipers to swing. The utility model can be widely used on various vehicles.
Description
The utility model belongs to motor washer, and particularly a kind of is the vehicle windscreen Windshield Wiper of feature with the transmission.
The Windshield Wiper that prior art is used divides electronic and pneumatic two kinds basically.And electric wiper can divide single motor-driven and Dual-motors Driving Windshield Wiper.
Existing single motor-driven Windshield Wiper is to drive a cover kinematic mechanism by motor output shaft, drive two rain brush kinematic mechanisms again by this cover mechanism, make the swing of two rain brush, the shortcoming of this Windshield Wiper is mechanism's complexity, consumption of power is big, needs bigger installing space, and installs, adjusts, keeps in repair all very difficult, the shortcoming of Dual-motors Driving Windshield Wiper is that consumption of power is big, and disadvantage is that also two rain brush stationary problems are difficult to solve.
The purpose of this utility model be the design a kind of simple in structure, power is little, remains the synchronous new vehicle Windshield Wiper of two rain brush during use, to overcome the deficiencies in the prior art.
The utility model purpose is achieved in that between two motors with a flexible axle forced synchronization, transmission system by two motors, the output shaft of two change-speed boxs drives two cranks, rocker mechanism respectively, and the fork of two rocker mechanisms drives the swing of two rain brush respectively, finishes the Windshield Wiper working in reciprocating mode.
Below in conjunction with accompanying drawing the utility model is described.
Accompanying drawing 1 is the utility model scheme drawing.
Accompanying drawing 2 is accompanying drawing 1 cut-away view.
Referring to accompanying drawing:
Electrical motor 1 drives worm gear 9 through worm screw 8, and output shaft 10 drives rocking bar 2 and rotates, and rocking bar 2 makes fork 4 swings through connecting rod 3, and fork 4 is captiveed joint with rain brush axle 7, the pendulum angle of angle " promptly " rain brush of fork 4 swings.Because each is driven two rain brush by an electrical motor 1, so the rotating speed of electrical motor is little may asynchrony phenomenon just appear two rain brush in full accord at work easily, with a flexible axle forced synchronization swing of two rain brush is consistent in the middle of two electrical motors.In order Windshield Wiper to be applicable to use under various environment and to be convenient to power supply on the car, electrical motor 1 adopts the double speed permanent magnet direct current motor.Adopt the flexible axle structure for the ease of synchronizing shaft 5 is installed, change-speed box 6 adopts worm gear, worm structure, and its advantage is that the converter speed ratio large volume is little.In order to make crank, rocker mechanism flexible, connecting rod 3 connects with adopting ball journal 11 being connected of fork 4 rocking bars 2.Change-speed box 9 and rain brush axle sleeve 12 are fixed on the frame 13 simultaneously.Frame 13 is directly installed on can finish the fixing of Windshield Wiper on the car body.
