System and method for removing rain from windshield of automobile

Abstract

The invention relates to a system and method for removing rainwater from a windshield of an automobile. The system comprises a windshield, a rainfall sensor, a switch, a high-speed air field generation assembly located in front of the windshield relative to the driving direction of an automobile, and a control device connected with the rainfall sensor and the switch, wherein the control device canstart or stop the high-speed air field generation assembly according to a signal of the switch or the rainfall sensor, the high-speed air field generation assembly comprises a high-speed air field generator and a barrier air field nozzle communicated with the high-speed air field generator, the high-speed air field generator can generate high-speed air flow and transmit the generated high-speed air flow to the barrier air field nozzle, the outlet direction of the barrier air field nozzle faces the windshield, and the high-speed air flow generated by the high-speed air field generator is jetted into a fan-shaped barrier air field according to control of the control device. Therefore, raindrops can be effectively prevented from falling on the windshield, rainwater attached to the windshieldis removed, and the sight of a driver is not disturbed during working.

Description

technical field [0001] The present invention relates to a system and method for removing rainwater from the windshield of an automobile, which removes rainwater or snowflakes (hereinafter collectively referred to as rainwater) on the windshield when rain or snow falls in a non-contact manner by generating an air field. ). Background technique [0002] Cars have become the main means of transportation in modern people's lives. In order to make cars run normally during rain and snowfall, a device for removing rainwater is usually installed before the windshield of the car to remove raindrops, snow water, etc. on the windshield in time. , to provide the driver with the required good line of sight, so that the car can drive normally and safely in rainy conditions, avoiding hidden dangers. [0003] Existing devices for removing rainwater from the front and rear windshields of automobiles usually adopt mechanical wipers, commonly known as wipers or windshield wipers. see Figure...

AI Technical Summary

Problems solved by technology

However, due to its friction with the windshield 3, it will cause wear to the windshield 3 and also accelerate the aging of the wiper blade 2.

On the other hand, even if the wiper blade 2 repeatedly cleans the windshield 3, dirt or dust will still remain on it, and the cleaning effect is not very satisfactory, and the best effect of clear vision cannot be reached.

Although this type of mechanical wiper is usually equipped with a water tank and nozzle 4 to help remove the dirt on the windshield 3, the cleaning effect is not good, especially after use, there will be water marks on the windshield 3 , bubbles, etc., in some cases more unfavorable

[0004] In addition, this reciprocating swing will inevitably affect and hinder the driver's driving line of sight, especially when the amount of rainwater is large, this device cannot remove all the rainwater on the windshield in time, and a part of the windshield is always covered with rainwater , which affects part of the driver's line of sight and poses a hidden danger to driving safety
