Abstract

The utility model relates to a rotary automatic compression windscreen wiper which is pivoted with two symmetrical subracks at two outer sections at the length direction of a main frame. The inner side segments of two subracks are respectively pivoted with an arc-shaped fixing frame. Two outer segments of the fixing frame and the outer side segments of the subracks are movably provided with clamping bodies. The calking groove point at the lower part of each clamping body and the strip frame-shaped metal clamping body are inserted. A double blade is preliminarily inserted in the metal clamping body and is inserted in the calking groove point of each clamping body with the metal clamping body. The middle section of the main frame is pivoted with two groups of symmetric compression mechanisms. The compression mechanism is composed of an airfoil-shaped pressing reed, a pivot shaft and a gear. The inner side segment of the compression mechanism of the main frame is provided with a preforce mechanism which acts on the compression mechanism. When the wind force exceeds the preset value, the pressurized fins automatically lift and press.

Description

Rotary automatic compression windscreen wiper

The utility model relates to automobile-used parts, and particularly a kind of sleet and fog that is used to strike off on the vehicle glass is employed rotary from the dynamic pressure rain brush.

Present automobile-used rain brush has two kinds, and a class is formed in one, and a kind of is to have swingable two chip architecture of scraping, though the former is simple in structure, strikes off weak effect.The latter is in order still to leave the problem of stain after solving the former and striking off, then adopt scraping back and forth and smear glass face when action, be alternately to contact and scrape and smear with glassy phase with two different scraping blades, but this Wiper structure complexity, and its blade insert or cleaning brush etc. all must be held or fixed by an integrated strip shape pole socket bar cramp, therefore, it lacks flexibility, make the scraping blade fixed on it or cleaning brush when contacting with glass surface because of really up to the mark generation of its rectangular seat bar presses distortion, cause scraping blade or cleaning brush scrape the face of closing and glass surface can't be combined closely.And as adopting resilient plastic cement to make rectangular seat bar, then meeting is out of shape because of aging after using a period of time, also can influence scraping blade and the closed contact of scraping the face of closing, therefore, all exists the problem of influence or forfeiture cleaning effect.The Windshield of especially most of automobiles is the fitfull cambered surface, and it is more outstanding that this problem then seems.

The purpose of this utility model just is to overcome the existing in prior technology deficiency, both can scrape resultant pressure and provide a kind of because of the corresponding change of wind-force size, again can by the direction of rain brush action not coplanar automatically different the scraping of the face of closing of scraping of transposing close effective rotary follow-up pressure rain brush.

The purpose of rotary follow-up pressure rain brush is to realize by following technical scheme:

Section is articulated with the assistant support of two symmetries outside body frame body length direction two, be articulated with the fixed mount of a bent body shape on two assistant support medial segments again separately, fixed mount two outside on section and the segmentum laterale of assistant support all active card clamp is housed, the caulking groove place and metal clip strip cabinet frame of each clamp bottom is inserted embedding mutually, two scraping blades then insert in advance in metal clip and with metal clip and together insert the caulking groove place that is embedded in each clamp, be pivoted with the pressing mechanism of two groups of symmetries in body frame body stage casing, pressing mechanism is by the pressurization fin of wing shape, pivot and gear constitute, pressing mechanism medial segment at the body frame body is equiped with the pre-force mechanisms that acts on mutually with pressing mechanism, when wind-force surpasses preset value, the pressurization fin starts automatically exerts pressure, and, scrape the plane of action that closes but clamp rotation certain angle also can change automatically because of the difference that scrapes direction because the presser feet activity of each clamp and hack lever is nested.

Therefore: remarkable result of the present utility model is:

1, because pressurization the ingenious of fin applies, makes scraping blade to be pressed or removes and exert pressure that can fit with glass surface all the time for scraping blade provide the actv. assurance, has improved cleaning effect along with the size of wind-force.

2, the setting of pre-force mechanisms makes that the predetermincd tension of fin can be regulated, to reach indirect control to the exert pressure size of pressure of fin.

3, because geometrical clamp and each pin of scraping blade or rain brush are that activity is nested, make clamp on the presser feet position, to rotate certain radian, so, scraping blade changes direction and scrapes and can move face when smearing certainly and carry out work, both guaranteed the service life of scraping blade, make elasticity, the abrasion loss of scraping blade keep the two sides identical again, improved applying effect with glass surface.
