What's the car triangle window for? It is said that 90% of car owners don't know.

I believe my friends have noticed that there is a special window in the car, which is triangular and looks different. But most of my friends don't know what this triangular window is for. Thought it was just a simple decoration. Today, Lungu will tell friends about its function, so that we can improve the posture of the car again.

Where do triangular windows often appear?

There are generally two kinds of triangular windows in the car. One is the triangular window on the side of the A-pillar, which we call the front door triangular window for the time being. The other is the triangular window near the C-pillar, which we call the back door triangular window for the time being. Let me talk about their functions respectively.

Front door triangular window

The common triangular window of the front door is the triangular window design between the front cross beam and the A-pillar. Now many cars are reserved directly on the front door.

The main function is to avoid the side blind area caused by the excessive inclination of the front windshield, which can increase the driver's vision. I think friends who drive will have a deep understanding of this.

In addition, the triangular window of the front door can also meet the requirements of the guide rail of the glass lifter, and the guide rail of the B-pillar and the glass guide rail need to be kept highly parallel.

Rear door triangular window

Generally, there are two kinds of triangular windows in the back door: one is installed on the back door and the other is installed on the C-pillar. Let's talk about the two separately.

Triangular window installed at the back door

The triangular window installed at the back door generally adopts the installation method of sealing strip on glass, mainly from the perspective of aesthetic design, which can make the whole car look more beautiful.

In addition, the manufacturing difficulty of the rear movable window can be appropriately reduced, and the size of the glass can be divided by the triangular window, so that the glass will be more stable when it rises and falls.

Fixed triangular window installed on C-pillar

The fixed triangular window installed on the C-pillar not only makes the whole car look beautiful, but also increases the lighting in the back seat, which meets the passengers' demand for the view.

In fact, the triangular window is not designed for driving vision, but for ventilation. In the early 1940s, a triangular window could be opened, which is why it has a window character.

What should I pay attention to in daily use of triangular windows?

Don't shoot the triangle window.

Don't stick the triangular window when sticking the car film. According to the regulations, the included angle of the front triangle window is not allowed to film, otherwise it will hinder the driver's line of sight. ?

Triangular windows don't match, they are more expensive.

Although the triangular window is not large in area, it is still very expensive because of poor matching. Don't be a triangular window at the back door, it's more expensive than a few big glasses in your car! Therefore, Lungu reminds friends that if your car key is unfortunately left in the car, don't smash it at the smallest triangular window, it is the most expensive one, so be sure to remember it.

Wheel valley summary:

First of all, the triangle has a stable function, so the triangle window has a good effect on the stability of the whole car frame.

The function of the triangular window of the front door: reduce the blind area and meet the requirements of the guide rail of the glass lifter. The role of the back door triangular window: beautiful, increase lighting, and make the glass rise and fall more smoothly.
