What is the reason why the car rear window glass is designed into two parts

Some cars' doors It's too long, and if it's made into a whole window, the window can't fall completely, so the rear triangle window may be on the door. There are also cars, car doorsAlthough the design is long, more glass is needed to optimize the field of view, so there is a design of two rear triangle windows.

After the power is on, the temperature of the glass rises, and no water vapor or frost will be produced on the glass, eliminating the potential for accidents.

Therefore, the designer divided the rear window glass of the car into two parts, one part is fixed, and the other part is liftable. The width of the liftable window glass is roughly close to the position of the door, and the minimum bottom length of the shape is also considered for lifting! The rear window can be divided into two parts. Of course, this design also makes the car more beautiful and generous as a whole.

Yes, in fact, you can look at this matter from another angle. If there are children at home, sitting in the back row of the car, the glass cannot be lowered 100%, which is also a protective measure, which is equivalent to adding a baffle.

Domineering. Large tires should be equipped with a large wheel arch. For some models, the shape of the wheel arch will make the lower half of the rear door panel narrow. When the rear window glass falls, the lower half of the door panel does not have enough space to accommodate the glass, which will cause the window glass to be unable to the end.

It turns out that the mysterious horizontal line on the rear glass of the car plays this role

In the freezing morning, the rear gear will freeze and frost, and the function of the defrost remover is to heat the rear gear glass. In the cold winter, the temperature difference inside and outside the car is very large. At this time, fog and frost will form on the rear window of the car. If you encounter a situation where you need to reverse, it is difficult for the driver to see the condition of the rear car through the rear window.

In general, what we often see are some red horizontal lines. The function of these resistance wires is to heat the glass. When you encounter some foggy weather, or the window is foggy, you can turn on the button. After the button is turned on, the resistance wire will start to work, and the fog in the car will gradually dissipate.

There is another function, which is the receiving antenna. You don't know this. Now some cars can't see the antenna, so where is the antenna installed? It's on these horizontal lines. It is very strong to receive signals one by one as antennas, because the coverage area is wider.

Is it necessary to stick the rear window film of the car

1. Theoretically, there is no need to stick the film on the car, unless it is always full, you can consider pasting the film on both rear windows for three reasons.

2. Although the car film has a certain effect of blocking heat and ultraviolet rays, the car rear window film is of little significance, and it is generally not recommended.

3. It's best to stick it, firstly, it can play the role of heat insulation, and secondly, it can play an explosion-proof role. Because the side and rear gear of the car are all tempered glass, once it is broken, it is full of small particles splashing everywhere, which is easy to cause safety hazards, but it will not be covered with a film. The front windshield of the car is the main heat source radiation area for the heating of the air in the car.

4. The rear window of Yinglang needs a film. The membrane has heat insulation, explosion-proof, anti-ultraviolet and other functions. If the weather is sunny and the sun is strong and you drive by yourself, you are much less likely to get sunburned. Especially for new cars, it is recommended to apply a glass film. If you have an old car, you also need to put a film on the car glass to take care of your car.

5. Regarding this problem, you need to deal with it according to your own preferences. There is no absolute conclusion on whether the rear glass needs to be filmed. Of course, it has an impact on the driving vision, because car film has both advantages and disadvantages, which needs to be measured and decided by individuals.

Can the window behind the car be opened?

1. Yes. The rear window of the Mercedes-Benz two-door e-class coupe can be opened. The rear glass of this car can be lowered separately. Tips: When driving at high speed, it is generally not recommended to open the window, but if you want to open the window, it is recommended to open the rear single window, and do not open the two windows on the same side at the same time.

2. The rear window is generally not opened while driving.There are horizontal lines on the rear window. Touch this horizontal line, and you will find that it is a film stuck to the glass! The driver observed the situation behind the car from the reflector above the cab. In winter, it is warmer inside the car than outside the car, and the rear window glass is prone to water vapor or frost.

3. First of all, it is not practical to open the rear windshield of the car, and it is also a test of sealing. This design is laborious and unpleasant.

4. During driving, when the car is fast, the biggest disadvantage of opening the window is that it will make a lot of noise. You can try to open diagonal windows, such as left front and right rear or right front and left rear windows. This can not only significantly reduce the noise, but also maintain the circulation of the air in the car.

5. The switch of the rear window of the car is located on the driver's door of the car.To use the switch of the rear window of the car, you need to start the engine of the car first and connect the electronic system of the whole car. The specific operation steps of using the switch of the rear window of the car are as follows: open the door on the driver's side of the car.

car rear window glass thin lines are so useful

1. These thin lines on the rear window are not It's all antennas, and most of them are heating wires.

2. One is the heating wire, also known as the defroster, which is similar to the "heating resistance wire". Multiple lines of "heating resistance wire" are evenly distributed on the rear glass of the car. The defroster is generally only available in the north. In the cold morning, the rear gear will freeze and frost. The function of the defroster is to heat the rear gear glass.

3. It can receive more stable signals. This method of integrating the antenna into the glass was first invented by Heinz Linden Meier, a professor at the Bundeswehr University in Munich. Because it is printed on the glass, it is also called a printed antenna, which uses the existing electric heating wire on the rear shield as the signal receiving line.

4. When the car encounters rainy and snowy weather, the rear windshield is foggy or snowy, the rear windshield heating function can be turned on to evaporate the fog and snow, and the obstruction of sight leakage.In addition to the heating function, some manufacturers also integrate vehicle signal receivers with heating lines, thus dividing vehicle antennas into several lines.
