Description
Technical Field
The invention relates to the field of automobile accessories, in particular to a sectional type windscreen wiper rubber strip structure.
Background
Chinese patent application No. 201710796672.1 discloses an automobile wiper rubber strip, which relates to the technical field of automobile part production, and is prepared by taking nitrile rubber, bismaleimide resin and polymethyl acrylate as main raw materials, adding dimethylbenzene, rosin, cationic starch, diisononyl ester and epoxidized soybean oil, adding various auxiliaries, heating, stirring, carrying out three-time freezing treatment, and carrying out hot melting.
Chinese patent application No. 201810360584.1 discloses a wiper strip including a strip main body made of a first rubber material and a blade portion made of a second rubber material; the knife edge part and the rubber strip main body are integrally co-extruded and molded. The rubber strip main body and the knife edge part are made of different materials so as to meet the requirements of the rubber strip main body and the knife edge part on respective use performance.
With the development of automobile technology, boneless wipers are being used by most automobile factories, and boneless wipers are equipped when most automobile models leave a factory; the main function of the bracket of the windscreen wiper is to support and fix a wiper rubber strip and uniformly disperse the downward pressure from the rocker onto the rubber strip, the boneless wiper disperses the downward pressure by means of the rebound force generated by 1-2 pre-bent reeds, and once the boneless wiper is produced and molded, the rebound force generated by the reeds pressing flat glass by the rocker is fixed.
However, the differences between wiper models are very large, according to the measurement example: the original-mounted cab boneless wiper of the 2015 type Haffh 6 has a length of 600MM, the actually-measured downward pressure of the rocker arm is about 600 gram force, the original-mounted cab boneless wiper of the 2015 type Audi A4L has a length of 600MM, the actually-measured downward pressure of the rocker arm is about 1100 gram force, along with the increasing preservation amount of automobiles, all manufacturers pay attention to huge after-sale markets, no matter international manufacturers or domestic manufacturers, in order to reduce the stock models and achieve good universality during designing of the wipers, the boneless wipers of the same series only can be designed with a spring leaf elasticity, the lower limit of the downward pressure of the rocker arms of most automobile types is adopted during designing of the spring leaf with small elasticity, the design of the spring leaf with small elasticity can ensure that the boneless wipers can be pressed and attached to glass in a flattening mode for most automobile types, scraping is not missed, but when the automobile type with large pressure of the rocker arms is used, the rubber strip close to the lower area of the wiper interface is subjected to overlarge pressure, and the section is quickly flattened to cause abnormal, water marks are generated, and the sight is influenced. In order to solve the problem, manufacturers increase the supporting force by integrally thickening the adhesive tape edge, but the integrally thickened design makes the adhesive tape edge integrally hardened, and the scraping attack angle is changed to generate new problems of jumping and scraping abnormal sound and the like.
