Description

Automatic regulating system for transmittance of window glass

Technical Field

The utility model provides a window glass transmittance automatic regulating system for automatically regulated window glass front windshield receives the transparency of shining the direct light department in the vehicle driving process, belongs to vehicle safety equipment and makes technical field.

Background

In the process of driving at night, if meeting a meeting vehicle, the light emitted by the opposite vehicles directly irradiates the eyes of the driver, and traffic accidents are easy to happen, so that a device capable of blocking the strong light when the strong light irradiates the eyes of the driver from the outside of the vehicle is needed to be designed, and the traffic accidents are avoided.

GB 7258-2017 technical conditions for motor vehicle operation safety stipulate that the visible light transmittance of the front windshield glass and glass except the windshield glass for the visual area part of a driver is more than or equal to 70 percent. The light transmittance of the automobile glass is generally 75% -80%, so if a front windshield is attached to the automobile film when the problem that the driver is exposed to strong light is solved, the light transmittance of the automobile film can meet the requirement only when the light transmittance reaches more than 90%. From the safety perspective, the sight of a driver can be seriously affected by the fact that a dark car film is attached to the front windshield glass, and especially when light is dark, great potential safety hazards can be brought. With the continuous upgrading and updating of the functions of the automobile glass, the quality requirement on the glass is higher and higher, and the quality problem caused by the introduction of new technology is also followed. Therefore, from the viewpoints of visual effect, humanization, intellectualization and the like, it is necessary to design an intelligent front windshield transmittance control system for an automobile.

After consulting a large amount of data and designing a large amount of experiments, the inventor finds that: conventional dimming glass solutions are available on the market PDLC (polymer dispersed liquid crystal), EC (electrochromic) and SPD (suspended particles). The intelligent dimming scheme newly introduced by Beijing east (BOE) can control dye molecules to rotate under the drive of voltage, change the transmittance and realize the continuous adjustment of bright and dark states. The PDLC light-adjusting glass is transparent when being powered on and is in a fog state when being powered off, and the application scene of the PDLC is limited due to the fact that the haze is large, so that the PDLC light-adjusting glass is suitable for being applied to meeting room partitions and cannot be widely applied to automobile glass.
