In many consumer concepts, the thicker the steel plate is, the safer it is. Even the thinner the skins are, the lower the safety of Japanese cars. It is a complete fault.

With the development of science and technology, the application of new information and new planning in thousands of miles a day, the safety function of car body can not be simply judged by the thickness of steel plate. This is like Big Brother's cellphone, when the thicker the battery, the longer the antenna pulled out, the more daunting the thinner, lighter the phone is now, and has more than a decade ago the era of brick machine people can not even imagine the high-tech skills.
Body steel plates also contain high technology that people could not imagine decades ago. At present, car data science is developing at a very fast speed. Under the premise of ensuring safety, lightweight and high rigidity of car body is an important development trend. On the one hand, it can reduce the weight of car body and save fuel, on the other hand, it can increase the space inside the car, speed up progress, reduce resonance, shorten the braking interval and so on.
The research shows that if the car component drops by 10%, the fuel power can be improved by 6%-8%; if the car quality is reduced by 100 kg, the fuel consumption of 100 km can be reduced by 0.3-0.6 liter, the car component can be reduced by 1%, and the fuel consumption can be reduced by 0.7%. Therefore, since 1994, the International Iron and Steel Association has been the first to open the "ultra-light steel car body" project. 35 iron and steel enterprises from 15 continents, 18 countries and 35 countries have participated in the project. They have jointly developed a series of new effects, such as high-strength body masks, ultra-high-strength body structures, lightweight suspensions and engine brackets. That is to say, the models now on the market, as long as they are formal manufacturers and car safety in-depth study of the car companies, are simply using this series of lightweight skills.
So now we choose a car, not to look at the thickness of the steel plate, and from what aspects should we judge the body safety function? This paper takes Lifan Xuanlang as an example, which is now widely regarded as an autonomous MPV model, for everyone to analyze.
First, steel plate information and stamping skills. For example, the body steel of Lifan Xuanlang is supplied by Baosteel, during which more than 50% of the body is made of high strength steel. Some of the steel plates are stamped by hot forming technology, which can effectively improve the compression resistance and deformation resistance of the body. The steel plate grade reaches the submarine standard and can fully guarantee the safety of the personnel in the vehicle when bump occurs.
Next, look at the concealed area of high strength steel. Lifan Xuan Lang mainly conceals in the front, rear, side wall, floor, column, roof and other local, including the entire crew cabin, and the door built-in Seamless High-Strength Steel beams, can withstand very strong instantaneous external impact, absorb most of the impact energy.
Third look at the body structure. Lifan Xuanlang chooses the cage body structure which is more popular now. It is composed of "impact retreat zone" and "high strength cockpit zone". The metal sheets of the body are bent and welded into the frame. When the body is knocked, the "impact retreat zone" folds up like an organ and absorbs the impact force, while the "high-strength cockpit area" ensures a complete living space for passengers.
Of course, high rigidity, lightweight body is only one aspect of car safety, but it is also the most important, any model can not be ignored, as consumers, should fully understand the connotation and value of high rigidity body, in order to truly grasp the safety in their hands.
