Car triangular windows, as the name suggests, are small triangular windows on cars. Its existence may make many people wonder, what is it for? Is it just designed for aesthetics? Is it dismantling or negligible? Depending on the installation location, there are two main types of car triangular windows: triangular windows on the front door and triangular windows on the rear door. They also serve different roles, but they are all designed to improve visibility, lighting, ventilation, comfort and safety for drivers and passengers.
The triangular window on the front door is mainly to reduce the side blind area caused by excessive tilt of the front windshield, so as to effectively expand the driver's field of vision. According to research, because the A-pillar of the car needs to meet a certain strength, the shape of the A-pillar of many cars is very thick. An 8cm wide A-pillar will make the driver's left side appear about 68°, about 2 on the right side3° blind spot. The listening degree is not large, 10 degrees are not reached, but in fact, more than a certain distance, the range of blind spots is actually relatively large. Or Southwest Jiaotong University, Master Jun Zhang** shares with you, "Research and Design of A-pillar Blind Spot Elimination System Based on TMS320DM642".
As mentioned above, the 6° blind spot angle covers more than 5 meters beyond 50 meters2 meters. What is the concept? The body length of a BMW 7 Series, a large BMW. In order to reduce the impact of blind spots caused by the A-pillar, many cars have made a triangular window under the A-pillar to improve this problem. The journal "Operator (Automobile Consumption Report)" also has **, the spear and shield of the car A-pillar", which is mentioned above. In order to be able to balance the issue of strength and visibility, the ingenious "triangular window" design was born. The existence of the triangular window can not only improve the strength of the A-pillar of the vehicle, but also ensure the driving vision.
In addition to increasing visibility, triangular windows on the front doors increase the amount of light and ventilation in the car. When driving on cloudy days or in tunnels, natural light is very important for the driver's vision. The triangular window can make up for the lack of light caused by the window glass and improve the visual comfort of the driver. At the same time, the triangular window can also allow more air circulation in the car, relieving the feeling of stuffiness in the car, thereby reducing the driver's fatigue.
In addition to the function of the triangular window on the front door, the triangular window on the rear door also has an important role, which is to allow the rear window to be raised and lowered freely. We used to ** "The rear window can't be lowered to the bottom, what is this design for?" is also mentioned. The back part of the rear window glass, looking vertically, actually pressed down the window has reached the position of the rear tire. As a result, the rear door panel as a whole is actually an oblique one, and the door panel as a whole is an oblique one. The window glass is going to go down, there is a place to put it, and it's hard to insert the glass into the tires underneath, right? The appearance of the triangular window solves this problem, it makes a triangle of the glass above the tire, and the rest of the glass can be raised and lowered freely. It's like: we put rice in a bowl, and if the rice is too big to fit in, I get rid of a little bit, isn't it still the same as the rice? Right?
The triangular window on the rear door can also increase the visibility and lighting effect of rear passengers, and improve the comfort of the ride. Li Ruirong published in the journal "Times Automobile", "Structural Design of Triangle Window of Rear Side Door", it is said that the design of triangle window not only considers the appearance effect and manufacturing quality requirements, but also needs to consider the vision and light transmission requirements. The design of the triangular window can obtain a larger viewing area and better lighting effect for the passengers in the car, which well complements the vision requirements of the rear personnel. The impact of the field of view on the comfort of rear passengers is actually quite large. It's a bit like: the same room, a room with a window is definitely more comfortable and comfortable to live in than a room without a window, and the reason is the same.
Through the above introduction, we can see that although the car triangular window looks inconspicuous, it has a role that cannot be underestimated. It can increase the vision and lighting effect of drivers and passengers, and reduce blind spots and potential safety hazards; It allows the rear window to be raised and lowered freely, increasing stability and safety; It also improves the structural strength of the body, reduces wind resistance and noise, and improves driving comfort. Therefore, when driving or riding in a car, we should pay attention to protect the triangular window and use it correctly. Don't wait until the car is scrapped to regret not cherishing this little part. The car triangular window is a subtlety in car design and a microcosm of car culture, which deserves our in-depth understanding and appreciation.
