We often see old drivers who like to brag that they know cars as well as they know themselves, but there is a place on a car that we can see every day. It is usually invisible. I won't pay attention. to it, but it has many uses and is very practical. This is a triangular window.
When you see this, you will be wondering what effect a triangular window can have, you should look for it carefully, that is, make car more beautiful. Is it really true? In fact, beauty is only part of role of triangular windows, and functions of triangular windows are also different in different parts. If you don't believe me, let's look down.
There are two types of triangular windows that we commonly see in cars: one is installed on front door, called A-pillar triangular window, and other is pressed against rear door, called C-pillar triangular window. Let's first look at functions of triangular A-pillar window.
In junior high school, we learned that when lengths of three sides of most stable triangle are determined, area and shape of triangle are completely determined. This property is called triangle stability, and car's triangle window is no exception. In design, triangle window acts as a stable corner, so unless car's exterior is seriously impacted, it will not be easily deformed under normal circumstances.
We also found that A-pillar triangular window position is very thin, right where windshield meets window, because sloped front windshield will interfere with driver's view to a certain extent. , so triangular window in A-pillar The design here is also designed to expand driver's field of vision and prevent traffic accidents caused by blind spots. Since it's mounted next to windshield to improve driver's view, will it help windows? Of course I have. A triangular window in A-pillar helps to raise and lower windows and glass smoothly and smoothly, preventing accidents.
A C-pillar-mounted triangular window mounted on a rear door is usually door-mounted or C-pillar-mounted. There is not much difference between C-pillar triangular window installed in these two locations. triangular window, triangular C-pillar window Windows can help rear passengers expand their field of vision. When getting out of car, it is convenient to observe whether there are people and cars passing in rear, and avoid safety accidents in rear caused by blindly opening door. And triangular window in C-pillar can also increase illumination inside car, making interior of car brighter. The C-pillar triangular window has two similarities with A-pillar triangular window: firstly, it is a smooth and stable lift rail that can help windows and glass, and secondly, it has excellent stability for whole car structure. .
However, when you "decorate" your car, you should not stick a triangular window on film. Do not choose triangular windows when breaking glasses, not to mention difficulty of matching, and money spent is more than four windows. It is better for your own wallet to be rational about car.
