Description
Technical Field
The application belongs to the technical field of glass, and particularly relates to a vehicle window glass device and a preparation method and application thereof.
Background
When strong light irradiates the eyes, the eyes of a person are dazzled, and dangerous situations are easy to occur, for example, when vehicles such as automobiles are driven, if the eyes of the driver are dazzled due to the light irradiation, the visual field of the driver becomes fuzzy, objects displayed in the visual field are not clear, and traffic accidents are easy to occur, so that the driver often wears devices such as sunglasses to avoid problems caused by strong light irradiation.
However, on one hand, wearing sunglasses makes the visual angle of the driver in a dark field, which causes the pupil enlargement of the eyes of the driver, and the pupil enlargement for a long time can cause the eyes of the driver to be degraded and damaged; on the other hand, the shading principle of the sunglasses is that light is absorbed and then diffused, and the principle that light is absorbed and then diffused leads a driver to be in a dim visual field, so that the pupil is in an amplification-reduction dynamic transition, and the pupil is in the dynamic transition in the driving process, so that the eyes of the driver are tired, the visual field becomes fuzzy, the position of things in the visual field is judged to be deviated, and traffic accidents are easy to happen.

Detailed Description
The application provides a vehicle window glass device and a preparation method and application thereof, and through the improvement of vehicle window glass components, a driver can avoid the irradiation of strong light without wearing sunglasses, and the technical problems of eye degeneration, damage and eye fatigue caused by the fact that the driver wears the sunglasses in the prior art are solved.
The technical solutions in the embodiments of the present application will be described clearly and completely below, and it should be understood that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The reagents or raw materials used in the following examples are commercially available or self-made.
Example 1
The present application example 1 provides a first silver halide based photochromic window glass device, in which the photochromic material is silver bromide.
The principle of silver bromide as a photochromic material is as follows:
and (3) decomposition reaction: 2AgBr ═ 2Ag + Br2The reaction conditions are illumination and heating;
and (3) combination reaction: ag + Br ═ AgBr.
Shine on window glass as the strong light source, be located the four light intensity sensors in window glass's four corners, can convert the intensity of acquireing light into digital signal to because four light intensity sensors set up four angles at on-vehicle glass respectively, so the light intensity that every sensor received is inconsistent, and when the strong light source was close to light intensity sensor, light intensity sensor's output can be great, otherwise, the output can weaken. The position of the strong light source is judged by comparing the output signals of the four light intensity sensors;
and then the light intensity sensor sends the position of the strong light source to the ultraviolet light generator, and the ultraviolet light generator can adjust the irradiation position through the motor and start ultraviolet light to irradiate corresponding car window glass, so that the silver bromide in the car window glass is subjected to decomposition reaction. Because the condition of the decomposition reaction is illumination, the ultraviolet ray with higher energy can effectively promote the decomposition direction of the silver bromide. Since the combination reaction of silver (Ag) atoms and bromine (Br) atoms needs to occur in a weak light, the combination reaction can be effectively suppressed under irradiation of ultraviolet light.
When the reaction of silver bromide proceeds to a certain extent, that is, the number of bromine atoms has already reached a certain extent. Because bromine is brownish yellow, the vehicle window glass is changed from colorless to brownish yellow, and strong light can be effectively resisted, so that signals received by the light intensity sensor can be greatly reduced. When the signal is reduced to be smaller than a set fixed value, the ultraviolet light irradiation module can be automatically closed, the decomposition reaction of the silver bromide is stopped, and the shading effect is achieved.
After the strong light source disappears, because a large amount of silver atoms and bromine atoms exist in the glass and the condition of weak light is met, the combination reaction can start to be carried out, and because the silver bromide atoms are colorless, the vehicle window glass can gradually recover from brown yellow to a colorless state, thereby completing the processes of color change and recovery once.
It should be noted that the light intensity sensor has a model number of GY-302. The sensor does not distinguish between ambient light sources and has an accuracy of 1 Lux (Lux).
Example 2
The second silver halide-based photochromic window glass device is provided in the embodiment 2, and the difference between the embodiment 2 and the embodiment 1 is that the photochromic material in the window glass is silver chloride, and the window glass changes from colorless to green under the strong light irradiation.
Example 3
A third silver halide based photochromic glazing unit is provided in example 3 of the present application, which example 3 differs from example 1 in that the light generator is an infrared light generator.
It can be confirmed from the above embodiments 1 to 3 that the light intensity sensors distributed at four corners of the window glass device provided by the present application can accurately position the irradiation positions of the strong light, so as to start the light generators such as ultraviolet light, etc., and irradiate the corresponding positions of the window glass, so that the photochromic atomic crystals such as silver bromide, etc. contained in the window glass are decomposed in the positive direction, and the decomposed yellow and green halogen is used to make the window glass appear dark colors such as brown yellow, green, etc., thereby blocking the irradiation of the strong light. Therefore, the problem that the normal driving of the driver is influenced by strong sunlight or high beam irradiation can be solved, and the vision of the driver can be protected from being damaged to the greatest extent;
compared with other light generators, the ultraviolet light generator well solves the problem that the existing color-changing glass is slow in color change after being irradiated by strong light. Compared with the common light irradiation, the color-changing glass is color-changed, the wavelength of ultraviolet light is short, higher energy is provided, the decomposition rate of silver halides such as silver bromide is accelerated, and the blocking effect of the car window glass on strong light is improved.
In the several embodiments provided in the present application, it should be understood that the disclosed apparatus and method may be implemented in other ways. For example, the above-described embodiments of the apparatus are merely illustrative, and for example, a division of a unit is merely a division of a logic function, and an actual implementation may have another division, for example, a plurality of units or components may be combined, some features may be omitted, or not executed. In addition, the shown or discussed mutual coupling or direct coupling or communication connection may be an indirect coupling or communication connection through some interfaces, devices or units, and may be in an electrical, mechanical or other form.
The foregoing is only a preferred embodiment of the present application and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
