Vehicle wiper device capable of automatically adjusting pressure

Abstract

The invention provides a vehicle wiper device capable of automatically adjusting the pressure. The vehicle wiper device comprises wiper blade modules, bracket modules and an air pressure module; the wiper blade modules comprise wiper blade frames; air discharging holes which are formed at equal distances and at intervals are formed in the lower end faces of the wiper blade frames; telescopic rodsare slidably assembled in the air discharging holes; the parts, extending into the wiper blade frames, of the upper ends of the telescopic rods are provided with limiting pieces; the upper ends of thewiper blade frames are connected with the bracket modules; air pipes are arranged in grooves; and the air pressure module comprises an air cavity. According to the vehicle wiper device capable of automatically adjusting the pressure, the air pressure formed by wind resistance during vehicle travelling is conducted to the wiper device to provide the downward pressure for a wiper; and meanwhile, when the vehicle speed is high, the downward pressure of wiper blades can be automatically increased.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an auto wiper device. Background technique [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 ...

[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 brush wall. After long-term use, the pressure of the spring will decline, resulting in insufficient pressure. Thereby make rain wiper device cleaning not clean; In summary, therefore there is defect
