Automobile wiper device with automatic pressure adjustment

Abstract

The invention provides an automatic pressure-adjusting automobile wiper device, which includes a scraper module, a bracket module and an air pressure module; Exhaust hole; a telescopic rod is slidably installed in the vent hole, and the upper end of the telescopic rod extends into the inside of the scraper frame to set a limit piece; the upper end of the scraper frame is connected to a bracket module; the An air pipe is arranged in the groove; the air pressure module includes an air cavity; the auto-adjusting pressure automobile wiper device is a kind of air pressure formed by the wind resistance of the automobile running to the wiper device to provide downforce for the wiper; at the same time A device that automatically increases the downforce of the wiper blade when the vehicle speed is high.

Description

Technical field [0001] The present invention relates to the field of auto parts, in particular, to a car wiper device. Background technique [0002] Car wiper is also known as a wiper, water-dial, wiper or windshield rain brush, is used to scrape the rain and dust from the vehicle windshield to improve the visibility of the driver, increase the safety; When the wiper blade is bonded to the car windshield, the car windshield has a certain pressure, thereby ensuring a good cleaning effect of the wiper device; however, the rain on the wiper Most of the rubber materials are made using rubber materials. Since the wiper is long-term exposed in the outside environment, the rain is easily aging, so that the pressure between the rain squeezes and the windshield becomes small and uneven, in scraping Water marks will be left on the windshield, which cannot clean the water stains and dust on the front windshield in front of the vehicle; in order to solve such problems, users must replace the...

AI Technical Summary

Problems solved by technology

[0002] Car wipers, also known as wipers, water dials, wipers or windshield wipers, are devices used to scrape off raindrops and dust attached to the windshield of vehicles to improve the visibility of drivers and increase driving safety; When the wiper blade of the existing wiper device is attached to the windshield of the automobile, it has a certain pressure on the windshield of the automobile, thereby ensuring that the wiper device can achieve a good cleaning effect; however, the rain on the wiper device Most of the wiper strips are made of rubber materials. Since the wiper device is exposed to wind and rain in the external environment for a long time, the wiper strips are prone to aging, which makes the pressure between the wiper strips and the windshield smaller and uneven. Sometimes it will leave water marks on the windshield, so that it is impossible to clean the water stains and dust on the front windshield of the car; Save the cost of using the car; when the car is running at high speed, the wind resistance of the car windshield increases, and the existing wiper blades cannot automatically increase the pressure on the windshield, which will also cause the car windshield to appear unclean. In addition, the existing automobile wiper device mainly guarantees the pressure of the wiper blade on the windshield of the automobile through the spring in the wiper arm. After long-term use, the pressure of the spring will decline, causing insufficient pressure. Thereby make rain wiper device cleaning not clean; In summary, therefore there is defect
