Detailed description of the invention
Above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing 1～4 and detailed description of the invention, the utility model is described in further detail.
A kind of telescopic single armed windscreen wiper system, comprises connecting rod, is fixed on scraping blade 11, spring 2 and cable wire 4 on connecting rod, and connecting rod is made up of head rod 1 and the second connecting rod 3, and first connecting rod 1 slidingtype is connected in second connecting rod 3. First connecting rod 1 comprises closing end 1-1 and openend 1-2, between closing end 1-1 and openend 1-2, form cavity 1-3, also be provided with guide groove 1-4 and operation guide groove 1-5 are installed at the inner surface of cavity 1-3, the second connecting rod 3 inserts to be installed after guide groove 1-4, in cavity, after 90 rotations, enter in operation guide groove 1-5, the second connecting rod 3 reciprocatingly slides along the axial direction of head rod 1 in operation guide groove 1-5.
Spring 2 is arranged in the cavity 1-3 of head rod 1, and its one end contacts with the end of head rod 1, and the other end contacts with the end of the second connecting rod 3.
Cable wire 4 one end are fixed on second connecting rod 3, and cable wire 4 other ends are fixed on the output shaft of the first motor 5, and second connecting rod 3 is under cable wire 4 tractive force, drive first connecting rod to carry out stretching motion by spring 2.
Second connecting rod 3 one end are also connected with the output shaft of the second motor 6, and the second connecting rod 3 swings along windshield under the drive of output shaft.
Adopt the control procedure of above-mentioned telescopic single armed windscreen wiper system to be:
First, taking windshield center as axle, windshield is divided into two regions, left and right, the left upper apex of left field is connected with summit, bottom right, then left field is separated into the first wiper district 7 and the second wiper district 8; Summit, right side area upper right is connected with summit, lower-left, right side area is divided into the 3rd wiper district 9 and the 4th wiper district 10.
Secondly, paste sensor at windshield inner surface, specifically comprise: the summit, lower-left in left field arranges first sensor 12, on the summit, upper right of left field, the second sensor 13 is set; In the left upper apex of right side area, the 3rd sensor 14 is set, summit, bottom right in right side area arranges four-sensor 15, the sensor model number adopting in the present embodiment is SME-2480, the detecting head of four sensors all upward, for gathering scraping blade positional information.
The scraping blade position signalling of sensor collection in the present embodiment is transferred to car body controller, car body controller integrated treatment input message, and then feedback corresponding signal control the first motor positive and inverse, that is control the flexible of wiper bar.
Comprise two parts a complete hunting period of wiper bar: the first is swung to the 4th region by first area; It two is to be swung to first area by the 4th region, wiper bar within the scope of windscreen taking 180 ° as cyclic movement. In the present embodiment, the swaying direction of the second connecting rod is determined by the second motor, is the working method of 180 ° of rotatings therefore set the second motor.
If scraping blade is by the first wiper region during to the 4th wiper regional movement:
When scraping blade moves to the first wiper region, if scraping blade positional information do not detected, to control the first motor and discharge cable wire, head rod makes Wiper crank overall elongated under the effect of spring force, and the scraping blade after elongation is cleared up the first wiper region;
When scraping blade moves to the second wiper region, if scraping blade positional information detected, to control the first motor movement and make spring-compressed, Wiper crank entire length reduces, and scraping blade continues the second wiper region to clear up again;
Repeat the processing procedure of scraping blade in the first wiper region when scraping blade moves to the 3rd wiper region, when scraping blade moves to the 4th wiper district, repeat the processing procedure of scraping blade in the second wiper region.
If scraping blade is by the 4th wiper region during to the first wiper regional movement, the reversion of sensor detected state, now:
When scraping blade is at the 4th wiper area operation, scraping blade positional information do not detected, to control the first motor and discharge cable wire, head rod makes Wiper crank extend under the effect of spring force, and the one or four wiper region is cleared up;
When scraping blade moves to the 3rd wiper region, if scraping blade positional information detected, to control the first motor movement and make spring-compressed, Wiper crank length reduces, then the 3rd wiper region is cleared up;
When scraping blade moves to the second wiper region, the first wiper region, repeat the processing procedure of scraping blade in the 4th wiper region, the 3rd wiper region.
Telescopic single armed windscreen wiper system in the present embodiment has auto-lock function, when car body controller does not collect signal, be sensor damage or control system inefficacy etc., car body controller can produce response, controlling the first motor makes it shrink cable wire 4, Compress Spring 2, to minimum duty, reduces wiper region to semicircle state, ensures that driver has the clear visual field of certain area.
Meanwhile, should be specifically noted that following item:
1. ensure that installation of sensors position is accurate, can not arbitrarily dismantle, affect sensor detection accuracy and life-span;
2. prevent dry scraping, in the time of non-rainwater operating mode, should first soak windshield, avoid, because frictional resistance damages motor greatly, causing the irrecoverable distortion of spring.
3. when use in winter, if scraping blade freezes, accumulated snow, not operation by force, needs to remove ice and snow, in order to avoid damage system.
Although more than described detailed description of the invention of the present utility model, but the those skilled in the art in this area are to be understood that, these only illustrate, and can make various changes or modifications to these embodiments, and not deviate from principle of the present utility model and essence. Scope of the present utility model is only limited by appended claims.
