Description

The vehicle glass face rainwater brush of convertible angle

The utility model relates to a kind of glass face rainwater brush, mainly refers to the rainwater brush of observer car wind glass face.

At present, the rainwater brush that the vehicle glass face is commonly used, as shown in Figure 1, form by big joint bone A, middle joint bone B, trifle bone C and rubber scraping article D etc., borrow compressing of rainwater brush swing arm (end shows among the figure), make and respectively save the change that bone itself produces curved arc, contact closely with the vehicle glass face and, scrape off rainwater and dirt thereof on the glass face through the drive that rainwater is brushed swing arm to adjust rubber scraping article D; But, because vehicle glass all becomes arc surfaced, and diverse location becomes different curved arcs, its cambered surface rate of different automobile types is also different in addition, yet, rubber scraping article D contacts with the close of vehicle glass face, then for the effect that compresses that helps rainwater brush swing arm, again because rubber scraping article D is arranged to vertical strip of vertical glass, cause rubber scraping article D flexural deformation more difficult, thereby, impel first that to compress deformation force bigger, second save the bone easy quick adjusting of the more healing and change different close contact curved arcs, but relative cost can improve, so general rainwater brush becomes under the excessive situation of arc in joint limited and fast quick-action of bone or glass, the gap that easily goes out to have wiper not to arrive produces, again since rubber scraping article D system contact with the vehicle glass face with leading edge, this leading edge then is positioned at rainwater brush swing arm and compresses on the line of action, friction force strengthens when causing swing, thereby the also raising relatively of the swing application of force of rainwater brush swing arm, and also easily causes the wearing and tearing of rubber scraping article.

In view of this, the purpose of this utility model is at big or middle, the joining place of joint between bone, cooperate so that interior projection and guide groove are movable, the joint bone can be done the swing of translation-angle in making, allow fixed rubber scraping article on the trifle bone again, higher rainwater swing arm compresses line of action, alleviates the contact force of rubber scraping article to the glass face, and the rubber scraping article is several.

The purpose of this utility model is achieved in that a kind of vehicle glass face rainwater brush of convertible angle comprises big joint bone, middle joint bone, trifle bone and rubber scraping article, it is characterized in that: at big joint epiphysis edge and middle joint bone central authorities joining place, be connected with the guiding groove hole kink with interior projection, in addition, between big joint bone and middle joint bone joining place, be provided with lining.Above-mentioned convex is an one with big joint epiphysis edge.Projection is the screw that is connected big joint epiphysis edge in above-mentioned.Projection is the rivet post that two ends are riveted on big joint bone two ora terminalis in above-mentioned.Projection is to be fixed on the projection that the lining in the big joint bone inwardly stretches out in above-mentioned.

Owing to adopt such scheme: can reduce the damage of rubber scraping article, the rubber scraping article is contacted with the close of glass face, can also promote the scraping effect.

Below in conjunction with drawings and Examples the utility model is further specified.

Among the figure: save projection, 7 guiding groove holes, 8 linings in bone, 3 trifle bones, 4 rubber scraping articles, the 5 fixed strip seats, 6 in the 1 big joint bone, 2.

First embodiment, shown in Fig. 2-4, it mainly is by big joint bone 1, middle joint bone 2, trifle bone 3, rubber scraping article 4 and fixed strip seat 5 are formed by combining, wherein big joint bone 1, middle joint bone 2 and trifle bone 3 slightly are different from commonly uses the rainwater brush, articulate with big joint bone 1 central authorities and rainwater brush swing arm, in 2 in bone of joint be articulated in big joint bone 1 ora terminalis place with central authorities, joint bone 2 ora terminalis places during trifle bone 3 is fixed in central authorities again, rubber scraping article 4 is to save in being clipped in admittedly respectively on the ora terminalis of bone 2 and trifle bone 3, and the joining place that saves 2 in bone 1 and middle joint bone greatly flexibly connects with projection in big joint bone 1 both sides 6 and guiding groove hole 7 (opening slotted eye) on the middle joint bone 2, certain decides the swing of angle to joint bone 2 according to interior projection 6 works in making, in order to make it swing smooth and easy and to avoid noise, 2 in bone of joint can add lining 8 in big joint bone 1 reaches again.

Second embodiment, as shown in Figure 5, the interior projection 6 that saves greatly on the bone 1 is the screw that is connected on big joint bone 1 ora terminalis, and the guiding groove hole 7 on the middle joint bone 2 is the sealing through hole.

The 3rd embodiment, as shown in Figure 6, the two ora terminalis inner bending still that saves bone 1 greatly becomes interior projection 6, and the guiding groove hole 7 on the middle joint bone 2 is the opening slotted eye.

The 4th embodiment, shown in Fig. 7,8, interior projection 6 is the rivet post on two ends are riveted on square 1 liang of ora terminalis of big joint bone, and the guiding groove hole 7 on the middle joint bone 2 is the sealing through hole.

The 5th embodiment, shown in Fig. 9,10, interior projection 6 is the rivet post on two ends are riveted on square 1 liang of riveting ora terminalis of big joint bone, and guiding groove hole 7 (sealing through hole) is on square 2 liang of walls of middle joint bone.

The 6th embodiment, as shown in figure 11, lining 8 is fixed in the square big joint bone 1, and lining 8 also inwardly stretches out two interior projections 6, and two guiding groove holes 7 are respectively the sealing through holes on middle joint bone 2 two sides.

Several rubber scraping article 4 sleeves of the present utility model (rubber-like steel disc or plastic cement material) on fixed strip seat 5, the rubber scraping article 4 that forms plural number is sandwiched on the ora terminalis of middle joint bone 2 and trifle bone 3 again, rubber scraping article 4 can be made large and small different size in case of necessity, be positioned to the height different conditions, tilt slightly in order to fixed strip seat 5, most rubber scraping articles 4 are posted simultaneously on the glass face.

When implementation and operation uses, rainwater brush swing arm will drive the swing back and forth of big joint bone 1, reach the middle joining place that saves 2 in bone and save bone 1 greatly, form the kink structure of displacement mutually with interior projection 6 and guiding groove hole 7, make vulcanite scraper be subjected to 4 resistibilitys that are subjected to glass, joint bone 2 is done the swing that certain decides angle with the wiper direction in can driving, make rubber scraping article 4 fixed on the trifle bone 3 become oppositely directed little shape that inclines in company with checker, the crimping edge line that forms with glass with inclination rubber scraping article 4 departs from the vertical active line that compresses big joint bone 1 of rain brush swing arm, and impel 4 one-tenth side sigmoids of rubber scraping article, thereby the drag that compresses distortion is less, so identical application force that compresses, can have moderate finite deformation effect and distortion adjustment faster, cause and to fit tightly on the glass face of different automobile types and continuous change radian, and do not have the generation in wiper gap, in addition since the crimping edge line of rubber scraping article 4 departed from the rain brush swing arm and vertically compressed on the active line of big joint bone 1, thereby the friction force can impel wiper the time reduces, relatively alleviated the swing application of force load of rainwater brush swing arm, and be difficult for causing the wearing and tearing of rubber scraping article 4, again with several rubber scraping article 4 sleeves on fixed strip seat 5, the plural scraping article that forms, when middle joint bone 2 is done certain swing of deciding angle with the wiper direction, then can post simultaneously on glass by most root rubber scraping articles 4, cause to have multiple wiper and promote the scraping effect, and it is more effective that rubber scraping article 4 is positioned to different height states.
