CN2224754Y - Antiglare glass for vehicles moving in opposite directions at night - Google Patents

Abstract

The utility model discloses an antiglare glass for vehicles moving in opposite directions at night. When the front windshield of the driver and the glass of two headlights are produced, the front windshield of the driver and the glass of two headlights are processed to have the polarization to the light and the penetrating directions are in a vertical plane and the included angle of the penetrating directions and the horizontal surface is 45 DEG, besides the technique requirement of the appearance. The antiglare glass has simple structure and is transparent and nearly colorless. The antiglare glass does not affect the sight of the driver. After the vehicle adopts the utility model, the antiglare glass not only can avoid the headlight of the other side from dazzling, but also can make the driver always clearly see the light rays emitted by own headlights when vehicles move in opposite directions at night. The antiglare glass for vehicles moving in opposite directions at night has ideal antiglare effect.

Description

The vehicle anti-glare glass of giving another the right of way night

The utility model relates to a kind of vehicle anti-dazzle device at night.

Various vehicles are when giving another the right of way night, and chaufeur not big light opening does not just see the loading situation and the actual width of the place ahead road conditions and the other side's vehicle.If big light opening must make the other side's chaufeur dazzle, dazzle the eyes, produce the blind area again, so very easily cause overturning, collide, hinder traffic accident such as pedestrian.Generation for fear of this traffic accident, there is the people that the headlight of vehicle is adapted as anti-glare light at present, it is when giving another the right of way, additional operations by both sides' chaufeur, change the power of the direction of illumination and the light of own automobile front lamp, briefly be exactly that you open that I close, I open your and close, thereby it is non-dazzing to reach both sides' chaufeur, sees the place ahead road conditions separately clearly.This glare reduction techniques not only makes the driver's operation trouble, can only singlehandedly grasp bearing circle when giving another the right of way, and also needs the tacit agreement of both sides' chaufeur to cooperate and just can finish.And anti-dazzle effect is to realize reluctantly that by both sides' chaufeur intermittent operation and the headlight illumination that reduces vehicle its effect is not ideal.

" vehicle night give another the right of way antiglare sheet " (hereinafter to be referred as antiglare sheet) utility application (application number: 95241577.1 that the utility model and the applicant submitted to Patent Office of the People's Republic of China on May 10th, 95; The applying date: on May 10th, 95) principle of comparing and antiglare effect are the same, but product configurations is different fully, and Applicable scope is also different.The former convenience type non-drying glue antiglare sheet be cambic it be applicable to the various vehicles that using, the latter then is applicable to just at the design-calculated new vehicle.

After adopting the utility model, not only overcome prior art---the weak point of anti-glare light, make vehicle before dispatching from the factory, just solve anti-dazzle problem at night, and more help the normalisation of vehicle, convenient user, service life is also longer than antiglare sheet.

The purpose of this utility model reaches by following measure: when making vehicle driver's front windshield and two headlight glass covers, except that technical requirementss such as outward appearance own, light transmittance, further processing makes it satisfy following 2 points again: first, it is made polarizability handle, make them have polarization characteristic light; The second, add the direction of shaking thoroughly that also makes them man-hour (or claiming polarization direction) all should be in vertical guide with the angle of horizontal surface in 10 ° to 80 ° scopes.

The give another the right of way night surface configuration of anti-glare glass of this vehicle can be designed to circle, rectangle and oval-shaped vehicle driver's front windshield and large lampshade as required.

Description of drawings is as follows:

Fig. 1 is an outside drawing of the present utility model.

Fig. 2 is the use location figure of the utility model on vehicle.

The sign 1 of Fig. 1 and Fig. 2 is the direction of shaking thoroughly of anti-glare glass.

The utility model is further described below in conjunction with embodiment, this vehicle anti-glare glass of giving another the right of way night, when being Windshield before making the vehicle driver and two headlight glass covers, except that technical requirementss such as outward appearance own, light transmittance, further processing makes it satisfy following 2 points again: first, it is made polarizability handle, make them have polarization characteristic light; The second, add the direction of shaking thoroughly that also should guarantee to make them man-hour all should be in vertical guide with the angle of horizontal surface be 45 °.The give another the right of way night surface configuration of anti-glare glass of this vehicle can be designed to Windshield and headlight glass cover before circle, rectangle and the oval-shaped chaufeur as required.Like this as long as all adopted vehicle of the present utility model when giving another the right of way night, because the direction of shaking thoroughly consistent (angle is zero) of shake thoroughly direction and the vehicle headlight anti-glare glass cover of anti-glare glass before both sides' chaufeur, and just in time form orthogonality relation (angle is 90 °) with the direction of shaking thoroughly of the other side's oncoming vehicle headlight anti-glare glass, so according to Malus' law: I=I ₀COS ²θ.(wherein: I ₀Be light intensity before the transmission; I is a light intensity after the transmission).Both sides' chaufeur produces frosting phenomenon when observing the other side's automobile front lamp, no longer dazzle the eyes, and can fully see the emitted illuminating ray of headlight separately simultaneously again clearly.And the secondary lamp (as Cornering Lamp, Fog-proof light, warning lamp etc.) of observing the other side's vehicle had no effect.

The utility model has following advantage compared to existing technology: this vehicle anti-glare glass of giving another the right of way night is easy to manufacture, and cost is not high, and antiglare effect is very desirable, the user is no longer included any requirement, and reach anti-dazzle function automatically.

Claims (2)

1, a kind of vehicle of making by polarized glass anti-glare glass of giving another the right of way night, it is characterized in that it shake thoroughly direction in vertical guide with the angle of horizontal surface in 10 ° to 80 ° scopes.

2, the vehicle according to claim 1 anti-glare glass of giving another the right of way night is characterized in that the surface configuration of anti-glare glass can be designed to circle, rectangle and oval-shaped chaufeur front windshield and automobile front lamp cover.
