Description

A kind of Windshield Wiper

Technical field

The utility model relates to the product that uses on a kind of automobile, is specifically related to a kind of Windshield Wiper of automobile air window glass.

Background technology

The Windshield Wiper of automobile air window glass is meant and is used for the parts of scraping automobile air window glass outer surface effectively, and it can bear the thrust of floating rule, and has one to be suitable for installing and the fixing support of scraping blade.Now the structure of the Windshield Wiper on the market is: the support of Windshield Wiper is formed by connecting by a plurality of component compositions such as long-armed, transition arm and galianconism, and these a plurality of members are respectively by rivet, and riveted joint place is isolated fixing with plastic bushing.

Because a plurality of members of Windshield Wiper are to be formed by connecting by rivet respectively, many one staking process in making fitting process, and also used rivet bar is corrosion-resistant steel, increased manufacturing expense; And the riveted joint crudy is difficult for stable; Rivet uses the blackout coating on rivet head surface, back easily to come off and shinny for a long time, and the exposed surface that can't reach Windshield Wiper is answered the requirement of blinding free phenomenon.

Summary of the invention

For overcoming the defective of prior art, the technical problems to be solved in the utility model provided a kind of easy to assembly, be connected firmly, cost is low, be easy to process and assemble, satisfy the Windshield Wiper that exposed surface is answered the requirement of blinding free phenomenon.

The technical solution of the utility model is: this Windshield Wiper, comprise long-armed, galianconism and transition arm, and be provided with scraping blade in the mounting groove at galianconism two ends, it is d that there is diameter at the middle part of galianconism ₁The galianconism through hole, the equal bifurcated in the two ends of transition arm be preceding fork and the back fork, it is D that preceding fork and back vent portion are provided with diameter respectively ₁First through hole and second through hole, it is d that a long-armed end has diameter ₁Long-armed through hole, long-armedly all be connected by attaching parts with transition arm, galianconism and transition arm, attaching parts comprises two cylinders at bridge shape parts two ends, the diameter of inboard cylinder and outer cylinder is respectively d and D, wherein d=d ₁, D=D ₁

Because a plurality of members of the present utility model are to be formed by connecting by attaching parts, avoided the use of rivet, so easy to assembly, be connected firmly, cost is low, be easy to process and assemble, satisfy the requirement that the automobile exposed surface is answered the blinding free phenomenon.

The specific embodiment

With reference to the accompanying drawings, will be described in detail the specific embodiment of the present utility model.

Fig. 1 is an overall structure scheme drawing of the present utility model.Windshield Wiper is generally formed by the component composition of a plurality of long-armed 7, galianconism 1, transition arm 2, and member is the amount doesn't matter, installs in the mounting groove 4 of galianconism and fixing scraping blade 6.Fig. 2 is the partial enlarged drawing of Fig. 1.Fig. 3 is that the A-A of Fig. 2 is to view.This Windshield Wiper comprises long-armed 7, galianconism 1 and transition arm 2, is provided with scraping blade 6 in the mounting groove 4 at galianconism 1 two ends, and it is d that there is diameter at the middle part of galianconism 1 ₁Galianconism through hole 11, the equal bifurcated in the two ends of transition arm 2 is preceding fork 21 and back fork 22, it is D that preceding fork 21 and back fork 22 are respectively equipped with diameter ₁First through hole 23 and second through hole 24, it is d that an end of long-armed 7 has diameter ₁Long-armed through hole 71, long-armed 7 all are connected by attaching parts 3 with transition arm 2, galianconism 1 and transition arm 2, attaching parts 3 comprises two cylinders at bridge shape parts 33 two ends, the diameter of inboard cylinder 31 and outer cylinder 32 is respectively d and D, wherein d=d ₁, D=D ₁Certainly, diameter D that also can first through hole ₁Diameter D with second through hole ₂Unequal, it is d that an end of long-armed 7 has diameter ₂Long-armed through hole 71, with long-armed be and attaching parts 3 similar second attaching partss with transition arm bonded assembly parts, second attaching parts comprises two cylinders at the second bridge shape parts two ends, and the diameter of the second inboard cylinder and second outer cylinder is respectively d ' and D ', wherein d '=d ₂, D '=D ₂

Fig. 4 is that galianconism and the transition arm of Fig. 3 installed preceding constitution diagram.The preceding fork 21 of transition arm and back fork 22 are uneven before installation.At first, the cylinder of attaching parts is inboard to be cooperated with galianconism through hole 11, the preceding fork of the transition arm before installing and back fork are uneven, i.e. punching out in advance is a trapezoidal shape, preceding fork with transition arm during assembling press-fits into shape shown in Figure 3 with the back fork, and galianconism 1 and transition arm 2 are linked together by attaching parts 3.As a same reason, long-armed 7 and transition arm 2 also link together by attaching parts 3 or with attaching parts 3 similar second attaching partss.

In addition, members such as galianconism, long-armed, transition arm all adopt cold continuous rolling high-quality mild steel plate or steel band punching out to form, and attaching parts adopts high performance plastics injection molded.Attaching parts has been isolated institute's bonded assembly steel component, when Windshield Wiper is worked, has avoided the friction between the steel component, has reduced motion noise, and is provided service life.
