High-pressure airflow automobile windscreen wiper

Abstract

The invention relates to the technical field of automobile parts, and discloses a high-pressure airflow automobile windscreen wiper. The high-pressure airflow automobile windscreen wiper includes an upper scraping arm and a lower scraping arm, the bottom of the upper scraping arm is fixedly connected with a supporting plate, and the bottom of the supporting plate is fixedly connected with an installation arm shaft, the bottom of the installation arm shaft is movably connected with an air jet mechanism, and the top of the upper scraping arm is fixedly connected with an installation mechanism; and the air jet mechanism includes an air pump, the output end of the air pump is fixedly in communication with a first air transmission pipe, one end, away from the air pump, of the first air transmission pipe penetrates through the installation arm shaft and the supporting plate and is fixedly in communication with the bottom of the upper scraping arm, and air circuits are arranged in the upper scraping arm and the lower scraping arm. According to the high-pressure airflow automobile windscreen wiper, rain water from a windscreen surface is convenient to remove, the damage of the windscreen wiper can be effectively avoided, the lower scraping arm is convenient to disassemble and assemble and maintain, and at the same time, the temperature of high pressure airflow is convenient to change,so that the internal and external temperature of an automobile windscreen is consistent.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a high-pressure airflow auto wiper. Background technique [0002] Wipers, also known as wipers, water dials, wipers or windshield wipers, are devices used to wipe off raindrops and dust attached to the windshield of vehicles to improve the visibility of drivers and increase driving safety. Cars almost everywhere have windshield wipers because they are required by law. Vehicles such as hatchbacks and recreational vehicles also have wipers on the rear windows. In addition to cars, other means of transportation are also equipped with wipers, such as trains and trams. Some engineering tools, such as cranes, are also equipped with wipers. [0003] When the existing car wiper is used in rainy days, because the surface material of the wiper is rubber, and the wiper is in direct contact with the windshield, after a long period of friction with the windshield, it is easy to cause th...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the automobile wiper in the prior art is used in rainy days, because the material on the surface of the wiper is rubber, and the wiper is directly in contact with the windshield, after a long time of friction with the windshield, It is easy to cause the wear of the wiper, which affects the effect of scraping the rain, and it is easy to cause scratches on the windshield, which affects the driver's viewing. A high-pressure airflow car wiper is proposed
