Abstract

The utility model discloses the blades used for the windshield wiper; the section thereof presents the shape like a Chinese character ''wang'', namely, three horizontal planes (1, 2, 3) and the vertical splice bar (4) used for connecting the three horizontal planes (1, 2, 3). Also, the extended splice bar (4) top is provided with the blades (5). The S-shaped groove (11) is arranged at the middle and supreme of the three horizontal planes (1, 2, 3) along the vertical orientation. As compared with the existing technology, this utility model sets up the offline groove on the back plane of the blade, so that when the wipers are bended, certain activity space will be available for the horizontal plane of the wipers so as to avoid the corrugation due to the extrusion of the horizontal plane. In this case, the bending deformation of the wiper could be smoothly carried out. Therefore, good elasticity is realized for both the wiper and wiper blade. Meanwhile, the good memory effect is achieved for the blade. So, the wiper could fit the windshield soundly to realize ideal wiping results.

Description

A kind of scraping article that is used on the wiper

Technical field

The utility model relates to the technical field of wiper on the automobile, is meant a kind of scraping article that is used on the wiper especially.

Background technology

At present, used wiper on the general-duty windshield on the market, include support and the scraping article that is fastened on the support, wherein scraping article generally adopts flexible materials such as rubber, and its cross section is " king " font, and the vertical dowel top in the middle of it has extended upward a page sheet, during use, drive support and scraping blade by motor-driven rocking arm, the page or leaf sheet that makes the scraping blade top is reciprocating friction Windshield in a fan-shaped range back and forth, wipes the water droplet and the impurity of glass surface then.Because of wiper need be applicable to different automobiles, and the radian of different its Windshield of automobile is just different, like this, scraping article on the wiper just need bend to different radians, thereby can be close on the Windshield of different radians, could guarantee the scraping effect of scraping article on Windshield.Simultaneously, wiper is when swiping Windshield back and forth, and the radian at its centre position of same Windshield and position, both sides is also slightly different, and like this, scraping article just needs frequent bending activity, coincide with Windshield to adjust at any time.But three Transverse planes in existing " king " font scraping article all are smooth surface, and quality is harder, when scraping article is crooked, these three Transverse planes all can play fold, and that a page or leaf sector-meeting is extruded into is wavy, and the own period of service of materials such as rubber one is long, particularly pass through Exposure to Sunlight, elasticity will reduce, so in the course of time, the page or leaf sheet is just easier be extruded into wavy, when scraping article frequent make flexion the time, can be difficult to be returned to former radian state, page sheet is coincide with Windshield completely, just can not guarantee the result of use of wiper, therefore, await improving.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, and a kind of scraping article that is used on the wiper is provided, and its flexural deformation is flexible, elasticity is better, and recovery effect is good, thereby guarantees that scraping article can coincide well with Windshield, makes wiper scraping effect very desirable.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the scraping article on the wiper, its cross section is " king " font, promptly have three Transverse planes and the vertical dowel that is connected these three Transverse planes, and this dowel top has extended upward a page sheet, it is characterized in that: longitudinally offer sweeping groove on the bottom surface in described three Transverse planes at least.

Described bottom surface is that plane that the cross section is in " king " font scraping article bottom in three Transverse planes, as a kind of improvement of the present utility model, can be on two other Transverse plane of " king " font scraping article the described groove of offering too in described cross section, promptly all longitudinally offer described groove on the lateral surface of three Transverse planes, thereby make the crooked deformation of three Transverse planes all very smooth and easy, flexible.

For further being beneficial to the scraping article distortion, can longitudinally have waist through hole in the side of described three Transverse planes and vertical dowel, more deformation space is reserved in setting up to scraping article of this waist through hole, further makes the scraping article bending more smooth and easy.

If groove is a linear, not to be bending, the frequent bending activity of scraping article so, just make three Transverse plane fractures of scraping article easily, for further guaranteeing the firmness of scraping article, described sweeping groove can be the not grooves on the same level line of various grooves two ends, promptly as S shape, Z-shaped groove etc., also can be various grooves two ends on same horizon, but the groove of the shape that protrude to a side at groove middle part, promptly as Ω shape, v-depressions etc. like this, just can not be in same straight line by groove, guaranteed that scraping article is when bending, Transverse plane all keeps continuously, and connects good, firmly, frequent again bending can not ruptured.

Compared with prior art, advantage of the present utility model is: by offer the non-linear groove on the bottom surface of scraping article, it is sweeping groove, when scraping article is crooked, certain activity space is provided for the Transverse plane of scraping article, avoid taking place the Transverse plane extruding and wrinkling phenomenon, make the crooked deformation of scraping article smooth and easy, flexibly, guaranteed that the cross section is its Transverse plane of scraping article and the page or leaf sheet better elastic of " king " font, page or leaf sheet recovery effect is also more satisfactory, so just can guarantee on the scraping article the page or leaf sheet can with good the coincideing of Windshield, make wiper scraping effect very desirable; And groove is arranged to bending, and guaranteed the good connection of scraping article Transverse plane under the case of bending, easy fracture not, service life is longer.
