Surface texture of windscreen wiper

Abstract

The windscreen wiper surface texture comprises a windscreen wiper strip and a triangular windscreen wiper blade rubber strip connected with the bottom of the windscreen wiper strip, the windscreen wiper blade rubber strip comprises a connecting part, a concave part and a wedge-shaped surface part, the bottom of the connecting part is connected with the concave part, the bottom of the concave part is connected with the wedge-shaped surface part, and the wedge-shaped surface part is connected with the connecting part. Groove textures are arranged on the two sides of the wedge-shaped face part. The invention aims to change rainwater existing when a windscreen is in contact with a wiper blade by introducing a groove texture on the surface of the rubber strip of the wiper blade, and a solid-liquid-solid contact state in a drainage state is converted into a solid-solid state through a groove, so that the drainage effect is enhanced. Different area rates, inclination angles, shapes, depths and the like have different changes on the friction force between the windscreen wiper and the windscreen, optimization design needs to be carried out in combination with different influence factors of actual conditions on the surface texture, the friction performance of a part surface contact friction pair is obviously improved, and therefore friction abrasion of the friction pair is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of wiper blades, in particular to the surface texture of wiper blades. Background technique [0002] Friction is a ubiquitous phenomenon in human production and life, and human beings have explored and utilized it for thousands of years. Friction refers to the interaction between two relatively moving surfaces, the process of which is the transfer of the entire energy of material wear, the destruction of the contact surface of the object and the loss of the entire material, especially in the process of mechanical operation. It plays an important role in the life of mechanical operation. From an economic point of view, friction and wear will always cause energy consumption and reduce the life of machinery, so the study of friction is of great significance to the entire national economy. [0003] Surface texture refers to the processing of micro-texture patterns such as pits and dents with a certain ...

Problems solved by technology

[0004] Tiny hard particles will appear on the windshield when the car is running in bad weather (strong wind, heavy rain, etc.), and the accumulated tiny particles will damage the wiper blade of the car, thereby reducing its service life and affecting the driver's field of vision; in addition, When the car is in contact with rainwater, the wiper blade is in contact with the windshield while there is a water medium in the middle, forming a solid-liquid-solid contact surface, which makes it impossible to completely remove rainwater and foreign matter
