Above-mentioned Modern car wiper, the length of described rain shaving blade wherein equals the length of described loop bar.

Above-mentioned Modern car wiper is hinged between described first cross bar wherein and described linear gear rack bar, and is also hinged between described rain shaving blade and described first cross bar.

Above-mentioned Modern car wiper, wherein said second motor is miniature motor.

Above-mentioned Modern car wiper, wherein said first cross bar is also hollow structure, and the left end in described first cross bar is also provided with the distance measuring sensor of the spacing of left end for measuring described first cross bar and described Windshield lower edge.

The invention has the beneficial effects as follows: by adopting the above-mentioned wiper bar structure containing loop bar, linear gear rack bar and the first cross bar, make the present invention can adjust the structure of wiper neatly, and effectively expand wiper scope, thus greatly improve driver's seat and driving safety.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.

Fig. 1 is the structural representation of Modern car wiper.

In figure: rain shaving blade 1, the first motor 2, loop bar 3, linear gear rack bar 4, first cross bar 5, gear 6, the second motor 7, slide block 8, upper limit position block 9, lower position block 10, distance measuring sensor 11.

Detailed description of the invention

As shown in Figure 1, a kind of Modern car wiper, be located at the outside of the Windshield of automobile, comprise rain shaving blade 1, wiper bar and the first motor 2 for driving wiper bar to carry out reciprocally swinging, wiper bar includes loop bar 3, linear gear rack bar 4 and the first cross bar 5, loop bar 3 is hollow structure, and the bottom of loop bar 3 is connected to the first motor 2, linear gear rack bar 4 is sheathed in loop bar 3, top in loop bar 3 is respectively equipped with the second motor 7 that the gear 6 that is meshed with linear gear rack bar 4 and driven wheel 6 rotate, slide block 8 is also provided with in the bottom of linear gear rack bar 4, both sides in loop bar 3 are also respectively equipped with the chute (not shown) for being embedded slide block 8, also be provided with upper limit position block 9 on the top being positioned at the loop bar 3 below the second motor 7 simultaneously, bottom in loop bar 3 is also provided with lower position block 10, the top of linear gear rack bar 4 is connected with the right-hand member of the first cross bar 5, the left end of the first cross bar 5 is also connected with the top of rain shaving blade 1 simultaneously.

Particularly, for above-mentioned Modern car wiper, wherein the second motor 7 is miniature motor.

By adopting said structure, when wiper performs wiper operation, loop bar 3 and linear gear rack bar 4 is driven to carry out reciprocally swinging by the first motor 2, and then drive rain shaving blade 1 reciprocal wiper on the Windshield of automobile by linear gear rack bar 4, thus the sleet can removed in time under sleety weather on windshield and dust etc., when wish regulates wiper scope or the region of rain shaving blade 1, just rotate by the second motor 7 driven wheel 6, then linear gear rack bar 4 is driven to move along the length direction of loop bar 3 by gear 6, or extend to the lateral direction of loop bar 3, thus upwards expand wiper scope, or extend to the direction, inner side of loop bar 3, downward expansion wiper scope, simultaneously, by arranging slide block 8 and sliding groove structure, more effectively can ensure the smooth linear motion of linear gear rack bar 4 in loop bar 3, and by upper limit position block 9 and lower position block 10, then can retrain linear gear rack bar 4 and slide block 8 moves between extreme higher position and extreme lower position, like this, by the relative position between flexible linear gear rack bar 4 and loop bar 3, rain shaving blade 1 just can carry out wiper to the region of failing before to touch or scope, thus finally greatly extend wiper scope, greatly improve the area of visual field of chaufeur thus, and ensure driving safety.

As preferably, for above-mentioned Modern car wiper, the length of rain shaving blade 1 wherein equals the length of loop bar 3.Like this, when linear gear rack bar 4 drops to extreme lower position, can ensure that the bottom of rain shaving blade 1 can extend the lower edge position of Windshield, thus be conducive to further eliminating wiper dead angle, ensure wiping effect.

As further preferred, above-mentioned Modern car wiper is hinged between the first cross bar 5 wherein and linear gear rack bar 4, and is also hinged between rain shaving blade 1 and the first cross bar 5.Like this, by above two connection location places are all being set to hinged, not only can flexible rain shaving blade 1 relative to the position of linear gear rack bar, all right clearance distance between flexible rain shaving blade 1 and Windshield, thus the thrust achieving adjustment rain shaving blade 1 pair of Windshield flexibly.In addition, pass through articulated structure, also achieving can angle between flexible rain shaving blade 1 and Windshield, to ensure that rain shaving blade 1 can be close on the windshield (even if for different vehicles) with Maximum Contact area all the time, thus further ensure actv. wiper region and good wiping effect.

As further preferred, for above-mentioned Modern car wiper, wherein the first cross bar 5 is also hollow structure, and the left end in the first cross bar 5 is also provided with the distance measuring sensor 11 of the spacing for the left end and Windshield lower edge measuring the first cross bar 5, like this, just can the residing on the windshield position range of real-time perception rain shaving blade 1, further facilitate the flexible to linear gear rack bar and the first cross bar.

In sum, by adopting said structure, making the present invention can adjust the structure of wiper neatly, and effectively expanding wiper scope, thus greatly improving driver's seat and driving safety.

By reference to the accompanying drawings the preferred embodiments of the disclosure and embodiment are explained in detail above, but the present invention is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, various change can also be made without departing from the inventive concept of the premise.
