Windscreen wiper connector suitable for U-shaped windscreen wiper arms and windscreen wiper

Abstract

The invention relates to a windscreen wiper connector suitable for a U-shaped windscreen wiper arm and a windscreen wiper. The windscreen wiper connector comprises a connecting base, a fitting body and a covering hood, wherein a set of longitudinal side plates extend in the fixed surface of the fitting body in the inserting direction of the U-shaped windscreen wiper arm; a set of limiting stops being opposite in positions is arranged on the inner wall of the set of the longitudinal side plates; the distance between every two of the set of the limiting stops is greater than or equal to the width of the windscreen wiper arm, so that when being mounted, the U-shaped windscreen wiper arm is free from being separated by the limiting stops and is easy to mount; besides, an elastic baffle plate extends downwards from the inner side surface of an upper cover, and when the upper cover and the base are closed, a gap is reserved between the elastic baffle plate and the limiting stops, and can beused for offsetting processing errors of a front end hook part of the U-shaped windscreen wiper arm caused by manufacturing, so that the suitability of products is good.

Description

technical field [0001] The invention relates to a wiper connector suitable for a U-shaped wiper arm and a wiper with the wiper connector. Background technique [0002] At present, the wipers used in the market generally have a wiper connector for matching with a wiper arm on a suitable vehicle. The conventional U-shaped wiper arm is connected to the wiper rod through the wiper connector. In order to prevent the wiper arm from falling off from the wiper connector, the patent publication No. CN1263835A discloses a wiper connector 10a, see figure 1 , 2 , the front end of which adds elastic clamping points 5a, 5c. When the U-shaped wiper arm 100a is installed, the front end of the U-shaped wiper arm 100a is nested in the elastic clamping points 5a, 5c of the wiper connector 10a, and the wiper connector The front end of 10a prevents the elastic deformation of the elastic clamping points 5a and 5c by tightly fitting with the wiper rod body 12a, so as to ensure that the U-shape...

Problems solved by technology

[0004] With the same idea, Bosch subsequently developed a flip-type wiper, patent number: 200580012836.2, see Figure 5 , which has a connector 84C, and the front end of the connector 84C also has a positioning crosspiece (elastic card point) 76C, and the front end 12C of the U-shaped scraper arm 10C is embedded in the connector 84C through the positioning crosspiece 76c, in order to To prevent the U-shaped scraper arm 12 from detaching from the connector 84C, a flip cover 50C is added at the rear end of the connector 84C, and the deformation of the positioning crosspiece 76C is prevented by buckling the flip cover 50C and the connector 84C. Provides a solution that can omit the positioning crosspiece 76C, that is, the limit joint 64C is set on the inner side of the flip cover 50C, referring to the 0007th natural paragraph of this specification, the limit joint 64C can directly act on the outer surface of the hook-shaped end. On the contour, that is, the positioning crosspiece 76C that does not rely on elastic deformation, the positioning crosspiece can be provided separately or can be canceled, so the limit joint 64C is rigid and does not have elasticity, otherwise if the limit joint 64C has elasticity, Then, during the wiping process of the wiper, the elastic boundary piece 64C cannot effectively prevent the U-shaped wiper arm 10C from being loosened from the connector 84C.

[0005] However, the above three technical solutions all have elastic clamping points on the wiper connector, and the minimum width between any of the above-mentioned elastic clamping points is smaller than the width of the U-shaped wiper arm. , it is necessary to overcome the bite force between the elastic card points on the wiper connector to be installed smoothly, and the installation is not easy; at the same time, due to the error in the processing of the U-shaped scraper arm, the distance between the tangent line of the outermost arc at the end of the hook and the center point The distance is different. When the distance between the outermost arc tangent and the center point is too long, it is easy to cause the hook-shaped end to be unable to be embedded inside the elastic clamping point, but directly interfere with the elastic clamping point, or even be located at the The outer side of the elastic card point loses the function of the elastic card point to limit the detachment of the U-shaped scraper arm; in the third background technology, although it provides a limit joint for replacing the elastic card point, but because the limit joint It is rigid and not elastic. Therefore, if the U-shaped scraper arm does not meet the processing requirements, the hook-shaped end may interfere with the boundary piece, so that the U-shaped scraper arm cannot be smoothly installed on the wiper connector.
