Windshield wiper strip support, forming method and windshield wiper sheet with windshield wiper strip support

Abstract

The invention discloses a windshield wiper strip support, a forming method and a windshield wiper sheet with the windshield wiper strip support. The windshield wiper strip support comprises a longitudinal slot which faces toward a windshield wiper strip and used for containing a back strip of the windshield wiper strip. The windshield wiper strip support is characterized by being provided with a back board extending in the longitudinal direction. A plurality of first lug parts and a plurality of second lug parts, wherein the first lug parts and the second lug parts are connected with the back board. The first lug parts are arranged on one transverse side of the back board at intervals, the second lug boards are arranged on the other transverse side of the back board at intervals, the longitudinal slot is formed by the back board, the first lug parts and the second lug parts in a surrounding mode, and the back board, the first lug parts and the second lug parts are all made of metal material. While the whole windshield wiper strip support has good strength, production cost is reduced. In addition, due to the fact that the first lug parts and the second lug parts are arranged at intervals, the whole windshield wiper strip support has reasonable rigidity and elasticity, and the whole windshield wiper strip support can be used smoothly.

Description

technical field [0001] The invention relates to the field of wiper blades, and more specifically relates to a wiper strip bracket, a forming method and a wiper blade with the wiper strip bracket. Background technique [0002] Chinese Invention Patent Publication No. CN101500862A discloses a wiper blade consisting of a wiper strip bracket, a wiper strip and an engaging element, the wiper strip bracket having a substantially rectangular hollow profile in cross-section with a Strip and for receiving the longitudinal slot of the back strip in the wiper strip, the wiper strip bracket has a groove in the region of the engagement element on the side of the wiper strip bracket opposite the engagement element, the groove has an undercut longitudinal side The longitudinal side wall matches the longitudinal side wall of the undercut in the longitudinal groove associated with the engagement element. [0003] In this way, it forms a dovetail connection with the undercut longitudinal sid...

AI Technical Summary

Problems solved by technology

[0004] Among them, the wiper strip bracket is made of one-time plastic injection molding, which generally has the disadvantages of low material strength, strong material brittleness, and poor fatigue resistance. In order to ensure the strength and service life of the wiper strip bracket, it is necessary to use more expensive Plastics even have relatively complex structures, and these will bring about problems in material cost, mold cost, and processing and molding, which have the disadvantages of high cost and difficult implementation
