[China Glass Network] When buying a car, few small partners pay attention to the glass. I don't know that the glass plays a vital role in the overall structure of the car body. There is even a part of the glass that hides a lot of black technology that you can't think of. Auto glass can also hide high-tech, and many small partners may not believe it, but this is absolutely true. Let's talk to the friends about the black technology hidden behind the glass.
First, the rain sensor function
The rain sensor function is what we call the automatic wiper, but its working principle is not known to many people. The sensor of the automatic wiper adjusts the speed of the wiper in a stepless manner according to the amount of rain falling on the glass. The rain sensor is hidden behind the front windshield. At present, most of the optical sensors are used to determine the amount of rain on the glass by the scattering of light in the glass and raindrops.
Second, the water function
When the car is driving on a rainy day, the rain on the windshield is dripping, which seriously affects the driver's sight and driving safety. In order to improve this situation, more and more models are using hydrophobic glass. Because this kind of glass is coated with an organic fluororesin on the outer surface of the front windshield, when the vehicle is traveling at a speed of 50km/h~60km/h, the raindrops on the glass surface will splash out. Good visibility can be maintained without the use of a wiper.
There are also some advantages to the hydrophobic glass, that is, the dust, dirt, wax, oil and the like on the surface of the glass are easier to remove. Of course, in today's market, there is also a glass flooding agent. As long as it is applied to the surface of the window glass, it can play a role in water immersion. However, as time goes by, the water flooding effect will gradually weaken. Reapply the water repellent.
Third, night vision function
Most of the night vision functions are assembled in luxury models. It uses far-infrared technology to make the darkness look as white, and the driver sees the line clearer and farther in the dark. At night, the instrument panel will become the display screen of the night vision system, and the position of the screen is in front of the driver. It is very convenient to observe. When the infrared detector detects pedestrians in front of the road, it will display a yellow sign to remind The driver should pay attention to safe driving.
Fourth, heating function
I don't know if my friends have observed that there is a lot of thin lines on the windshield behind my car. Is this a simple decoration? Of course not, this is a black technology. When the glass temperature of the rear window of the car rises, these lines can achieve the effect of evaporating water vapor and frost. Of course, this function is basically not used when the spring sun (parameter, picture, inquiry) is bright, but when it is cold or rainy, the temperature difference between the inside and outside of the car is large, and a thin layer of fog appears in the rear glass. Or frost, then the driver can not observe the rear through the rearview mirror, especially when reversing, this heating function is particularly intimate.
Five, anti-fracture prevention through the front block
Driving on the road Almost all the drivers have encountered the cracking of the glass that was suddenly flying. At this time, the sadness of the little friend reminds me of the understanding of the talents. What is even more terrible than this is that the front windshield is penetrated.
Super front glass is stronger than ordinary glass for impact and penetration resistance. Even if the car encounters any spatter in the speed of 120km/h~250km/h, it will not split, and any throwing objects will not penetrate because It is the surface treatment technology of the aircraft cabin glass, so it also solves the problem of the automotive industry for hundreds of years, but there are still many gaps with the bulletproof glass.
Sixth, HUD head up display
How does the HUD look up? In fact, it is a head-up display system, which is currently used in aircraft aids. It can display the important information on the dashboard on the front windshield by mapping. The driver no longer needs to be a “low-headed family†to look at the information on the dashboard. Of course, there will be more energy on the road. In the dangerous situation observation, because the driving safety is greatly improved, but the system is too expensive, and it is currently used in a few luxury models.
