Cable wire 4 one end is fixed on second connecting rod 3, and cable wire 4 other end is fixed on the output shaft of the first motor 5, and second connecting rod 3 drives first connecting rod to carry out fore and aft motion under cable wire 4 tractive force, by spring 2.
Second pipe link 3 one end is also connected with the output shaft of the second motor 6, and the second pipe link 3 swings along windshield under the drive of output shaft.
Embodiment 2:
A control method for telescopic single armed Wiping device, adopts above-mentioned telescopic single armed Wiping device to realize, comprises the following steps:
Step 101: four the wiper regions obtaining windshield, are specially:
First, with windshield center for axle, windshield is divided into two regions, left and right, the left upper apex of left field is connected with bottom right vertex, then left field is separated into the first wiper district 7 and the second wiper district 8; Right side area right vertices is connected with bottom left vertex, right side area is divided into the 3rd wiper district 9 and the 4th wiper district 10.
Secondly, paste sensor at Windshield inside face, specifically comprise: first sensor 12 is set at the bottom left vertex of left field, the second sensor 13 is set at the right vertices of left field; In the left upper apex of right side area, the 3rd sensor 14 is set, at the bottom right vertex of right side area, four-sensor 15 is set, the sensor model number adopted in the present embodiment is SME-2480, the detecting head of four sensors all upward, for gathering scraping blade location information.
The scraping blade position signal of sensor collection in the present embodiment is transferred to car body controller, car body controller comprehensive treatment input information, and then feedback corresponding signal controls the first motor positive and inverse, that is controls the flexible of wiper bar.
Step 102: the swaying direction obtaining the second pipe link, in the present embodiment, a complete oscillation period of wiper bar comprises two parts: the first is swung to the 4th region by first area; It two is swung to first area by the 4th region, wiper bar within the scope of windscreen with 180 ° for cyclic movement.In the present embodiment, the swaying direction of the second pipe link is determined by the second motor, therefore setting the second motor is the mode of operation of 180 ° of rotatings.
Step 103: control Wiper crank work according to swaying direction, comprise following process:
If scraping blade by the first wiper region to the 4th wiper regional movement time:
When scraping blade moves to the first wiper region, if scraping blade location information do not detected, then control the first motor release cable wire, head rod makes Wiper crank overall elongated under 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 location information detected, then control the first motor movement and make spring-compressed, Wiper crank entire length reduces, and scraping blade continues to clear up the second wiper region again;
Repeat the treating process 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 treating process of scraping blade in the second wiper region.
If scraping blade by the 4th wiper region to the first wiper regional movement time, sensor detected state reverse, now:
When scraping blade is at the 4th wiper area operation, scraping blade location information do not detected, control the first motor release cable wire, head rod makes Wiper crank extend under spring force, clears up the one or four wiper region;
When scraping blade moves to the 3rd wiper region, if scraping blade location information detected, then control the first motor movement and make spring-compressed, Wiper crank length reduces, then clears up the 3rd wiper region;
When scraping blade moves to the second wiper region, the first wiper region, repeat scraping blade in the 4th wiper region, the treating process in the 3rd wiper region.
Telescopic single armed Wiping device in the present embodiment has auto-lock function, when car body controller does not collect signal, i.e. sensor degradation 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 mode of operation, 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 sensor mounting location is accurate, arbitrarily can not dismantle, affect sensor detection accuracy and life-span;
2. prevent dry scraping, when non-rainwater operating mode, first should soak windshield, avoid because friction drag is large and damage motor, causing the irrecoverable distortion of spring.
3., during use in winter, if scraping blade freezes, accumulated snow, do not run by force, need ice and snow be removed, in order to avoid damage device.
Although the foregoing describe the specific embodiment of the present invention, the those skilled in the art in this area should be appreciated that these are only casehistorys, can make various changes or modifications, and do not deviate from principle of the present invention and essence to these embodiments.Scope of the present invention is only defined by the appended claims.
