Hit into a slim car, people who seriously injured or died in traffic accidents, in the past more than 100 years of the car, had a surprising traffic accident that had a variety of shocking traffic accidents. A person’s life can be more fragile, and it is reflected in a serious traffic accident. Nowadays, the car has already entered thousands of households, making it the most intimate partner of people’s daily travel, and the safety performance of cars has also become a problem that requires high attention.
The safety of the car can be roughly divided into two blocks of active safety and passive safety, and when the collision accident is inevitable, the passive of the vehicle The safety level determines the safety of the personnel in the car, so this is also the meaning of the Work of American IIHS, China’s C-NCAP, China and Branch and other collision testing agencies. These institutions use different orientation collision tests in the market, and release the collision test scores and maintenance economics for consumers. At the same time, they also urge the car companies to use the body structure. Reduce costs, also reduced passive safety performance of the vehicle. In particular, after the introduction of the medium-sized research, it can be found that the intensity of the consumer to the car A column can be described as strong attention. So what is the so-called A column, why consumers care about it?
Generally, from the front windshield of the car seat The windshield is three columns in both sides, according to the ABC order, the column on both sides of the front windshield is called an A column, and the front and rear vehicle doors are the B column, and the back windshield is the column, some models There is also a D column constructed. The consumer will pay attention to the intensity of the car A column, because there have been “the mirror” title of “photo mirror” research on 25% biased collision, detecting a few hot-selling models in the market, lack of strength, In the collision, the A-column has even broken, and the firewall of the vehicle has also caused harm to the fake people due to the collision of the crew.
If you still don’t quite understand the importance of the A column intensity, then you can use the car crew to be a house, andA column, B column, and c column are the load column of the house. If the load column intensity of the house is not enough, then the house will have a hidden danger. Similarly, when the vehicle crashes at a rapid occurrence of a rapid speed, if the huge impact force generated by the collision, if the A column of the car produces a deformation or break, then the occupant’s living space will be compressed, causing the occupant. The injury and even fatal risk factors will be higher. However, if the steel used by the vehicle A column is a super high strength steel, there is no deformation or break in the collision, then the intact passenger cabin naturally reduces the injury and death rate of the occupant in the vehicle. This is also why consumers have such concern to the intensity of the car A column. After all, their own vehicles passively and safely related to their own safety, and life can only be once.
Consumer’s intensity of the car A column in the collision test is so strong Also, on the side, consumers have higher security awareness. In the past, consumers car purchase more attention to this car looks not to the grade, the degree of extent, the price is high, whether the performance is strong, etc., the information of the vehicle is not much better. And when the car company is publicizing the new car, the introduction of safety performance is not the focus.
However, the domestic car ownership has reached 270 million, and the traffic jam on the road can be said to be home. Coupled with electric bicycles on the road, pedestrians can be said to be relatively complicated. The highway in holidays, big jams have also been blamed. When the road conditions are more and more complex, the hidden risk of driving while driving is higher, so consumers are more concerned about the safety of their own travel, and they will also pay attention to the active and passive safety performance of their favorite vehicles. You know, when a collision occurs, no one can predict how the consequences will be produced.
