A self-adaptive pressure regulation automobile wiper control method

Abstract

The present invention provides a method for controlling an automobile wiper with adaptive pressure adjustment, the method is realized based on an automobile wiper device, and the device includes a blade module, a bracket module and an air pressure module; the blade module includes a blade frame , the lower end surface of the scraper frame is provided with exhaust holes arranged at equal intervals; 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. A bracket module is connected to the upper end of the scraper frame; an air pipe is arranged in the groove; the air pressure module includes an air cavity; The formed air pressure is transmitted to the wiper device to provide downforce for the wiper; at the same time, it is a device that can automatically increase the downforce of the wiper blade when the vehicle speed is high.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to an automobile wiper control method for adaptive pressure regulation. 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....

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
