Wiper

Abstract

The invention discloses a wiper which comprises a main supporting framework, an elastic adjusting part, at least one auxiliary framework, at least one secondary framework and a connecting seat. The elastic adjusting part has a certain radian and is fixedly connected onto the main supporting framework, the auxiliary frameworks are movably connected onto the main supporting framework and have a certain swinging degree of freedom on the main supporting framework, the secondary frameworks are movably connected onto the elastic adjusting part and have a certain swinging degree of freedom on the elastic adjusting part, the connecting seat is mounted in the middle of the main supporting framework, and a connecting groove is formed in the connecting seat. The wiper is simple to assemble, force can be uniformly applied to a wiper component, so that the wiper component can be effectively fitted with glass, foreign matter removing effects are improved, the wiper can be connected with various wiper arms, the wiper is convenient to use, and production cost and assembly can be reduced.

Description

technical field [0001] The invention relates to a wiper blade, which belongs to the technical field of wiper blades. Background technique [0002] At present, the automobile wipers of the prior art generally include a wiper arm and a wiper strip. The fixed end of the wiper arm is pivoted on the automobile, and the movable other end of the wiper arm is pivotally connected to the wiper strip. The fixed end of the wiper arm is The shaft pivots and swings to drive the scraper to sweep the windshield of the car. At present, the wiper brackets are mainly divided into bracket type wipers and boneless wipers. The bracket type wipers are composed of a main bracket and an auxiliary bracket. The structure of the bracket is generally a stamped and bent part. The force applied to each point on the blade is uneven, and the swing angle of each part is also uneven. The rigidity of the steel blade of the cartilage type wiper is not easy to optimize. Too low rigidity of the steel blade will ...

AI Technical Summary

Problems solved by technology

At present, the wiper brackets are mainly divided into bracket type wipers and boneless wipers. The bracket type wipers are composed of a main bracket and an auxiliary bracket. The structure of the bracket is generally a stamped and bent part. The force applied to each point on the blade is uneven, and the swing angle of each part is also uneven. The rigidity of the steel blade of the cartilage type wiper is not easy to optimize. Too low rigidity of the steel blade will result in insufficient force when wiping. Too high will cause the wiper blade to be unable to stick to the glass, so no matter whether the rigidity is too high or too low, rainwater and foreign matter cannot be completely removed; different types of wiper arms, and each manufacturer has different types of wiper arms. The same wiper cannot be connected with multiple types of wiper arms. It is very inconvenient to use and is not conducive to mass production.
