Novel windscreen wiper

Abstract

The invention provides a novel windscreen wiper. The novel windscreen wiper comprises a steel sheet, a windscreen wiping strip and a rubber sleeve, wherein the windscreen wiping strip is connected with the steel sheet; the rubber sleeve coats the steel sheet; mounting support points of a bracket and the steel sheet are two scattered support points; the distance between the two support points is greater than 50mm. Compared with the prior art, the novel windscreen wiper has the advantages that the bracket is additionally arranged between a windscreen wiping arm and the steel sheet, and the bracket provided by the invention differs from the conventional bracket that the distance between the two mounting support points of the bracket is longer and is 60 to 180mm, so that uniform stress is applied to force-carrying positions of the steel sheet, and the pressure on the windscreen wiping arm is lowered; the steel sheet is connected with the bracket through a buckle rather than compacted tight fixing, so that the steel sheet can be bent by sliding in the bracket so as to be attached to a glass surface; moreover, the buckle can be pre-arranged on the bracket, so that a flattening procedure can be omitted, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of wiper components, in particular to a new type of wiper. Background technique [0002] Existing windshield wiper generally divides two kinds, and a kind of is to have bone wiper, and a kind of is boneless wiper. [0003] The bone wiper is the connection between the wiper arm and the rotating shaft of the wiper. The rotating shaft of the wiper is connected to the wiper strip through a skeleton-shaped connecting rod. Several supporting points on the connecting rod press the wiper strip on the glass, so that the wiper The pressure of each support point on the bar is averaged. The transmission of the pressure is through the car wiper arm → main connecting rod → secondary connecting rod → fixed point of the wiper strip, and finally the force is transmitted to the wiper strip through the steel grip on the wiper strip. The advantage of the bone wiper is that the pressure of the wiper strip is uniform, it is wel...

AI Technical Summary

Problems solved by technology

However, this connection method has the following disadvantages: 1. The force of the steel sheet is concentrated in the middle, while the car glass has a curvature, so the end of the wiper strip cannot fit the glass well, and there are cases where there are water marks on both ends of the wiper

Moreover, because the force is concentrated in the middle of the steel sheet, the pressure requirements of the wiper on the wiper arm of the car are also relatively large; 2. The fixed points of the rotating shaft bracket are concentrated in the middle of the steel sheet, and the distance between the fixed points is relatively small, usually within 50mm. The distance between the fixing points of the wiper bracket is more than 50mm. The fixing method of this bracket is no longer applicable, because when the middle part of the steel sheet is completely fixed, the middle steel sheet cannot be properly deformed to fit the curved surface of the car glass, resulting in Water marks appear when the water is not wiped clean; 3. The clamping position of the existing metal bracket usually needs to add a flattening process to compress the steel bar, and the production efficiency is low
