Bead elimination scheme of vehicle rearview mirror and vehicle window glass

Abstract

The invention relates to a bead elimination scheme of a vehicle rearview mirror and vehicle window glass, wherein a hydrophilic washing liquid which is rich in a surfactant, has good water affinity and can markedly reduce the interfacial tension of water is used for eliminating beads, a spray device is formed by adding a washing pump, a water pipe, a cable, a spray head and a control switch to a traditional washer kettle on a vehicle, the spray head is arranged on a rearview mirror and/or a vehicle window decorative cover plate, the appearance problem of the spray head is solved through an inlaid or built-in mode, and the hydrophilic liquid is simultaneously sprayed on the rearview mirror and the vehicle window glass to immediately eliminate the beads and keep no sticking of the beads within a period of time.

Description

Technical field: [0001] The invention belongs to the technical field of auto parts design, and in particular relates to a scheme for eliminating water droplets on automobile rearview mirrors and vehicle window glass. Background technique: [0002] On rainy days, the outside rearview mirrors (rearview mirrors for short) and the front side window glass (window glass for short) are covered with water droplets and affect the driver's sight has always been a major traffic hazard. Many methods have been invented to solve this problem: [0003] (1) Mechanical type, such as installing wipers, etc., has a disadvantage of complex structure and unsightly appearance. [0004] (2) The electronic type, such as ultrasonic water removal, has a complex structure and cannot remove water drops on the window glass. [0005] (3) Blowing type, with electric fan blowing and natural air guide, although the structure is simple, the effect of removing water droplets is not good. [0006] (4) Electr...

AI Technical Summary

Problems solved by technology

[0003] (1) Mechanical type, such as installing wipers, etc., its disadvantage is that the structure is complicated and not beautiful

[0004] (2) Electronic type, such as ultrasonic water removal, etc., has a complex structure and cannot remove water droplets on the window glass

[0005] (3) Blowing type, with fan blowing and natural air guide, although the structure is simple, but the effect of removing water drops is not good

[0006] (4) Electric heating type, that is, adding electric heating wires behind the lens. This is the only technology put into use at present, but it can only defrost, and the effect of removing water droplets is not good, and it cannot remove frost and water droplets on the window glass

[0007] (5) Liquid spray type: that is, spray liquid to the rearview mirror to remove water drops. Although there are many better methods, they are not perfect

For example, in the Chinese utility model patent with the notification number CN2413953Y, the water nozzle affects the appearance of the rearview mirror and cannot remove the water droplets on the window glass

Another utility model patent with the announcement number CN201021262Y, the nozzle is directly installed on the door, which seriously affects the appearance

A common defect of these methods is that the design of the nozzle is neglected, which will affect the appearance of the whole vehicle or the rearview mirror, and there is no improvement to the sprayed liquid, and the use of ordinary water or existing cleaning fluid to remove water droplets is very poor.

[0008] To sum up, so far, people have not found a comprehensive, perfect and practical solution to eliminate water droplets on car rearview mirrors and window glass
