Abstract

The utility model relates to a front windshield, and particularly relates to a variable color front windshield. The variable color front windshield comprises a common glass layer and an optical glass layer, and a film is clamped between the common glass layer and the optical glass layer. The variable color front windshield mainly solves the problem of difficulty of a current automobile windshield in preventing intense light from interfering with the sight of a driver, not only reduces interference of the intense light with the sight of the driver, but also effectively reduces temperature in a cab.

Description

The changeable colour front windshield

Technical field

The utility model relates to Windshield, particularly a kind of changeable colour front windshield.

Background technology

The front windshield of existing vehicle all can not variable color, the sunburst in summer is mapped on Windshield, not only the eyes of chaufeur very easily are subject to the stimulation of high light, cause the dimness of vision, and high light is rushed across glass and can be made the temperature in operator's compartment raise, thereby make the chaufeur tired spirit, be easy to accident.

Nowadays, normally adopt the mode of pasting solar film on the car inner glass in summer, and install an air-conditioner to reduce temperature in operator's compartment, but aforesaid way can't be avoided the strong interference on Driver Vision.

The utility model content

The purpose of this utility model is to provide a kind of changeable colour front windshield, it mainly solves existing windshield and is difficult for intercepting the interference problem of high light to pilot's line of vision, it not only reduces the interference of high light to pilot's line of vision, but also can effectively reduce the temperature in operator's compartment.

For achieving the above object, the utility model is to realize like this.

A kind of changeable colour front windshield is characterized in that: it comprises simple glass layer and optical glass layer, sandwiched film between this simple glass layer and optical glass layer.

Technique effect of the present utility model is:

1, reduce the interference of high light to pilot's line of vision;

2, effectively reduce the temperature in operator's compartment;

3, increase the intensity of Windshield.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Refer to Fig. 1, the utility model discloses a kind of changeable colour front windshield.As shown in the figure: it comprises simple glass layer 1 and optical glass layer 2, sandwiched film 3 between this simple glass layer 1 and optical glass layer 2.

Simple glass of the present utility model once 1 main component is silicate, and the optical glass layer 2 in the utility model also has the composition of potassium except silicate.This optical glass hardness is large, not easy to wear, and visibility is good, and, in the glass for lenses of manufacturing light-sensitive sunglasses, except general raw material, also to add the tiny crystal grains of appropriate silver halide and aerugo, after making eyeglass, when being subject to strong illumination, silver halide wherein can be decomposed into silver and halogen.Because it is dark that the particulate of silver is, so colour of lens just deepens.When light dimmed (weak), silver and halogen are under the effect of catalyst oxidation copper, and chemical combination generation silver halide again, so the color of eyeglass has shoaled again.So the secret of variable color is the decomposition of silver halide under different condition and regroups.According to experimental results show that: the light-sensitive sunglasses eyeglass is by solar radiation after 5 minutes, and the high light by eyeglass can decay to original 50%; After eyeglass is kept out of the sun 5 minutes, can recover light 23%, after about 1 hour, can return to original true qualities fully.Because the silver halide added and aerugo combine together with optical glass; so light-sensitive sunglasses are variable color repeatedly; the long-term use; can protect eyes to avoid high light stimulates; photo chromic glass general look color after variable color mainly contains grey and dark brown two kinds; in the selection of flash glass, can answer client's hobby to select and grey, the flash glass of dark brown mixing variable color.

The foregoing is only preferred embodiment of the present utility model, not be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should be technology category of the present utility model.

Claims

1. a changeable colour front windshield, it is characterized in that: it comprises simple glass layer (1) and optical glass layer (2), sandwiched film (3) between this simple glass layer (1) and optical glass layer (2).
