Abstract

The utility model discloses a novel wiper blade of a car. The wiper blade comprises a snap spring, a fixed seat, turbulence wings, spring leaves, an adhesive tape and end covers, wherein the snap spring is arranged inside the upper end of the fixed seat; the lower end of the fixed seat is provided with a slot; the spring leaves are fixedly arranged in the slot of the fixed seat; the turbulence wings are sleeved on the spring leaves; the adhesive tape is fixedly arranged at the bottoms of the spring leaves; and the end covers are respectively sleeved at two ends of the spring leaves and are fixed with two ends of the spring leaves. The wiper blade has the characteristics of attractive appearance, small volume and light weight; the variety and the number of parts are greatly reduced, thereby facilitating the manufacturing and assembling, and effectively reducing the cost; as the two spring leaves are made of same materials, the manufacturing precision can be reduced; the turbulence wings are made from rubber-plastic co-extrusion materials with relatively high rigidity, and thus the wiper blade has a good anti-falling property; and as the overall height is reduced and the wiper blade is made of light materials, the wind resistance can be effectively reduced, the wiper blade is prevented from being blown off, and the use effect of the wiper blade is guaranteed.

Description

A kind of new automobile scraping blade

Technical field

The utility model relates to motor, more particularly, relates to a kind of new automobile scraping blade.

Background technology

Traditional automobile scraping blade generally comprises nearly 10 kinds of jump ring, permanent seat, the flow-disturbing wing, spring leaf, adhesive tape etc., amounts to nearly 20 parts, thereby has following a plurality of shortcomings:

1, fitting process is comparatively complicated, and operation is long, and difficulty is higher;

2, the quantity of spring leaf is three, and material is not identical yet, is respectively corrosion-resistant steel (304), carbon tool steel (SK5) material, makes accuracy of manufacture have relatively high expectations;

3, stream the wing and adopt softer elastomeric material, in use easily come off;

4, the scraping blade volume is larger, and the size higher (35mm) of permanent seat top to adhesive tape bottom, easily increases windage, and in galloping, wind-force easily blows scraping blade to hike up, and can't with glass gluing, cause scraping blade effect price differential;

5, outward appearance is also not succinctly attractive in appearance.

The utility model content

For the above-mentioned shortcoming existed in prior art, the purpose of this utility model is to provide a kind of new automobile scraping blade, can reduce parts, reduces and manufactures and assembly difficulty.

For achieving the above object, the utility model adopts following technical scheme:

This new automobile scraping blade, comprise jump ring, permanent seat, the flow-disturbing wing, spring leaf, adhesive tape and end cap, described jump ring is located in the permanent seat upper end, the permanent seat lower end is provided with draw-in groove, spring leaf is fixedly arranged in the draw-in groove of permanent seat, and the flow-disturbing wing is sheathed on spring leaf, and adhesive tape is fixedly arranged on the spring leaf bottom, end cap is set in respectively on the two ends of spring leaf, and fixes.

The quantity of described spring leaf is two, be arranged side by side in draw-in groove, and the middle part of each spring leaf is provided with fixedly bayonet socket, in order to the boss with corresponding setting in draw-in groove, tightens mutually fixing; Described adhesive tape upper end is placed between two spring leafs.

The two ends of described each spring leaf also are respectively equipped with the anti-back bayonet socket, in order to the boss with corresponding setting in end cap, tighten mutually fixing.

The material of described two spring leafs is identical, is carbon tool steel.

The material of the described flow-disturbing wing is rubber and plastic co-extrusion material.

Described jump ring adopts polyformaldehyde material, and described permanent seat adopts the PBT+PET-GF30 material, and described adhesive tape adopts natural rubber or nitrile rubber material, and described end cap adopts the polybutylene terephthalate material.

Described permanent seat top to the height of adhesive tape bottom is 28mm.

In technique scheme, new automobile scraping blade of the present utility model comprises jump ring, permanent seat, the flow-disturbing wing, spring leaf, adhesive tape and end cap, described jump ring is located in the permanent seat upper end, the permanent seat lower end is provided with draw-in groove, spring leaf is fixedly arranged in the draw-in groove of permanent seat, the flow-disturbing wing is sheathed on spring leaf, and end cap is set in respectively on the two ends of spring leaf, and fixes.This scraping blade has the characteristics such as outward appearance is good, volume is little, lightweight, by kind and the quantity that significantly reduces parts, thereby facilitated, manufactures and assembling, effectively reduces cost; And adopt two identical spring leafs of material can reduce its accuracy of manufacture; The flow-disturbing wing adopts the relatively hard rubber and plastic co-extrusion material of quality, has slip-off preventing preferably; By reducing its whole height, and adopt light material to make, can effectively reduce windage, avoid scraping blade to be blown and hike up, guaranteed the result of use of scraping blade.

The accompanying drawing explanation

Fig. 1 is the schematic perspective view of scraping blade of the present utility model;

Fig. 2 is the elevational schematic view of scraping blade of the present utility model;

Fig. 3 is that A-A in Fig. 1 is to cross-sectional schematic;

Fig. 4 is that B-B in Fig. 2 is to cross-sectional schematic.

The specific embodiment

Further illustrate the technical solution of the utility model below in conjunction with drawings and Examples.

Refer to shown in Fig. 1～Fig. 4, new automobile scraping blade of the present utility model comprises jump ring 1, permanent seat 2, the flow-disturbing wing 3, spring leaf 4, adhesive tape 5 and end cap 6 these six kinds of parts altogether, wherein, described jump ring 1 is located in permanent seat 2 upper ends, and permanent seat 2 lower ends are provided with draw-in groove, and spring leaf 4 is fixedly arranged in the draw-in groove of permanent seat 2, two flow-disturbing wings 3 are sheathed on respectively on the left and right sides of spring leaf 4, adhesive tape 5 is fixedly arranged on spring leaf 4 bottoms, and end cap 6 is set in respectively on the two ends of spring leaf 4, and fixes.Wherein, the quantity of described spring leaf 4 is two, be arranged side by side in draw-in groove, and the middle part of each spring leaf 4 is provided with fixedly bayonet socket 7, fixedly bayonet socket 7 can adopt the form of dual-mouth, tighten mutually fixingly in order to the boss with corresponding setting in draw-in groove, play the effect of stationary spring 4 and adhesive tape 5; And described adhesive tape 5 upper ends are placed between two spring leafs 4 and fix.The two ends of described each spring leaf 4 also are respectively equipped with anti-back bayonet socket 8, and this anti-back bayonet socket 8 can adopt the form of single-bayonet, in order to the boss with the interior corresponding setting of end cap 6, tighten mutually fixingly, play the effect that prevents that end cap 6 from exiting.In addition, the material of described two spring leafs 4 is identical, is the carbon tool steel as SK5.The material of the described flow-disturbing wing 3 is rubber and plastic co-extrusion material.In order to make this automobile scraping blade expendable weight, all the other each parts adopt respectively following material: described jump ring 1 adopts polyformaldehyde (POM) material, described permanent seat 2 adopts the PBT+PET-GF30 material, and (PBT is the polybutylene terephthalate, PET is the polyethylene terephthalate, GF30 is 30% glass fibre), described adhesive tape 5 adopts natural rubber (NR) or nitrile rubber (NBR) material, and described end cap 6 adopts polybutylene terephthalate (PBT) material.The height of described permanent seat 2 tops to adhesive tape 5 bottoms is designed to 28mm.
