It is moved on the downside of windshield the influence caused by driver that makes a noise and is less than sending when rain brush swings to windshield centre
Make sound influence caused by driver.So the rain brush that the present invention designs swings to windshield interposition in rubber flap 5
When setting;Rubber flap 5 can be away from the side movement of windshield;And rubber flap 5 is when swinging on the downside of windshield;Rubber
Glue scraper plate 5 can be towards close to the movement of the side of windshield.
Specific embodiment: when the windshield wiper that people are designed using the present invention;Driving motor 6 is opened to switch;So that
Driving motor 6 works;I.e. 6 shaft of driving motor rotates;The rotation of 6 shaft of driving motor drives rain brush swing rod 3 to swing;Rain brush swing rod
3, which swing three drive blocks 2 of drive, swings;Since drive block 2 is corresponding to two C-shaped plate springs 10 in 3 swing process of rain brush swing rod
Under the action of be always positioned at the centre of arc-shaped guide rail 8.So three swings of drive block 2 just will drive three arc-shaped guide rails 8 and swing;
Three arc-shaped guide rails 8, which are swung, successively drives two the 6th rubber fixed plates, 20, two the 5th rubber fixed plates, 19, two the first rubbers
Glue fixed plate 4, two the 4th rubber fixed plates, 18, two third rubber fixed plates 17 and two the second rubber fixed plate 16 pendulum
It is dynamic;Two swings of third rubber fixed plate 17 just will drive the swing of scraper plate fixed plate 14;Scraper plate fixed plate 14, which is swung, drives rubber
Scraper plate 5 is swung;Rubber flap 5 can first swing certain angle in 5 swing process of rubber flap, then to by swinging to keeping out the wind
Glass is cleared up;When rubber flap 5 swings to windshield middle position during the swing and connects with the stuck mechanism of rain brush
When touching;Rubber flap 5 will stop swinging;But driving motor 6 also will continue to rotate at this time;So driving motor 6 will drive rain
Brush swing rod 3 and drive block 2 continue to swing;The swing of drive block 2 can compress corresponding C-shaped plate spring 10;Drive block 2 swings meeting band simultaneously
Dynamic drive rack 11 is swung;The swing of drive rack 11 just will drive the rotation of second gear 9;9 rotation driven gear of second gear turns
Axis rotation;Rotary gear shaft rotation drives first gear 7 to rotate;The rotation of first gear 7 drives spool gear 23 to rotate;23 turns of spool gear
It is dynamic to drive contracting rack gear 12 mobile away from the side of windshield;Side mobile band of the contracting rack gear 12 away from windshield
Dynamic scraper plate fixed plate 14 is mobile away from the side of windshield;A sidesway of the scraper plate fixed plate 14 away from windshield
It is dynamic to drive rubber flap 5 mobile away from the side of windshield;That is rubber flap 5 and the contact area of windshield subtracts
It is small;It, which is acted on, is reduced because rubber flap 5 carries out in wiping process in the windshield to automobile, and rubber flap 5 is wiping
When changing on direction;Because windshield sends out rubber flap 5 relative to windshield the extruding force of rubber flap 5
Life beats and makes a noise;When driving motor 6 stops operating;Drive block 2 can be gradually restored under the action of C-shaped plate spring 10
Position originally;In 2 recovery process of drive block;Rubber flap 5 can also be restored to original position;When driving motor 6 is reversed
When rotation;The rotation of 6 shaft of driving motor will drive 3 backswing of rain brush swing rod;3 backswing of rain brush swing rod drives three drivings
2 backswing of block;Three swings of drive block 2 just will drive three 8 backswings of arc-shaped guide rail;Three arc-shaped guide rails 8 swing according to
Two the first rubber fixed plates 4, two the 4th of the 5th rubber fixed plate 19, two of the 6th rubber fixed plate 20, two of secondary drive
18, two third rubber fixed plates 17 of rubber fixed plate and two the second rubber fixed plates 16 are swung;Two third rubber are fixed
The swing of plate 17 just will drive 14 backswing of scraper plate fixed plate;Scraper plate fixed plate 14, which is swung, drives 5 backswing of rubber flap;In
Rubber flap 5 can first swing certain angle during 5 backswing of rubber flap, then be carried out clearly by swinging to windshield
