Blade-free wiper system of automobile

Abstract

The invention discloses a novel blade-free wiper system which comprises a wiper drive mechanism, wiper arms which are connected to the wiper drive mechanism and can be driven to move by the wiper drive mechanism, and ultrasonic transmitters positioned at the ends of the wiper arms. The blade-free wiper system improves the wiping effect without causing abnormal sounds due to the friction of bladesagainst glass.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, in particular to an automobile wiper blade-less wiper system. Background technique [0002] The wiper is a component that is mainly used to clean the rain, frost and snow on the front windshield, so that it can ensure that the front windshield can also have a good view in rainy weather. In addition, the wiper will also be used to clean up the dirt on the windshield, such as the dust after long-term parking, the muddy water splashed on the windshield when off-road, and the water after the rain. Because of air pollution, the burden on the wipers is obviously much heavier, and the frequency of use is very high. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] 1. In rainy days, when the rainfall is heavy, it is necessary to turn on the high-speed wiper, but this does not guarantee the dr...

AI Technical Summary

Problems solved by technology

[0004] 1. In rainy days, when the rainfall is heavy, it is necessary to turn on the high-speed wiper, but this does not guarantee the driver's good vision and affects the safety of driving;

[0005] 2. In the conventional wiper system, the wiper blade is in direct contact with the front windshield glass. The pressing force and the degree of fit between the wiper blade and the glass directly determine the wiping effect. It is difficult to control on the real car, and it is easy to cause dirty wiping and pressure. Abnormal friction noise caused by excessive tightening force, resulting in complaints from customers;

[0007] 4. The rubber strips currently on the market are made of synthetic rubber, and the life span is generally 8-12 months. The life span is short, which increases the later use cost; and the aging of the rubber strips in the later stage affects the scraping effect, resulting in a decrease in driving safety
