When it comes to Japanese cars, there are always many friends who talk to me about car safety. "The iron sheet is thin!", "The car is too light!" The people who hold such arguments seem to be a lot of people around me, and such a "people cloud and cloud" seems to have been passed down for a long time and become the so-called "truth." Is the Japanese car really unsafe? FAW Toyota uses the new Corolla “All-round Safety†science laboratory to spread knowledge about car safety.
Many of my friends are actually not just “talking to hearsayâ€. They will go to the 4S shop and have real experience contact with the real car, and the heavy closing sound seems to be more popular with consumers. Indeed, the heavy closing sound seems to represent a series of "invisible safety" such as the thickness of the door panel and the materials used. There were two kinds of closing sounds on the experimental scene. It seems that there is a special feeling of heavyness, but when the mystery is revealed, it is not difficult to find that these sounds can be deliberately dealt with. As long as the damping rubber and the sound-insulating cotton on the door are handled properly, the same door can obtain two completely different sound effects.
"That car is safer at least in collisions? This should be physical knowledge!" But it seems that Toyota has subverted this traditional understanding with its own experiments. Toyota's own hybrid electric vehicle Prius and flagship model crown weights of 1420kg and 1700kg, respectively, but in the 64km / h collision test between the two did not show the crown has an overwhelming advantage.
“Which steel plate thickness can determine safety?†But it seems that things are not as absolute as we think. Two doors, also from Corolla, gave very different results when subjected to a 20kg free fall, and the thickness of the steel plates was exactly the same. The result of this is mainly the side impact steel beam structure from the inside of the door. Under the same steel plate thickness, the structure seems to help us get the desired result.
Professor Zhang Jinchang, a car safety expert from Tsinghua University, and the famous racing driver Lu Binglun, also shared knowledge about car safety. The two showed their experience and knowledge of car safety through comparative imagery and their own car experience. As the authoritative collision mechanism in China, C-NCAP also showed the new five-star safety collision results of Cola and the specific subjects of C-NCAP collision in this scientific laboratory activity.
Regarding the passive safety design of the car, Toyota engineers explained the Corolla's GOA body design. GOA body technology is unique to Toyota. It is a passive safety technology developed after repeated collision experiments based on the safety standards of most countries in the world, combined with the actual occurrence of accidents. Its core technology is a body structure with a high-intensity cockpit and efficient absorption of impact energy. When the car is at the moment of impact, the safety body cuts and absorbs the collision force in a self-sacrificing manner, and then distributes the force evenly to the skeleton of each part of the body through the integral body, while the cockpit uses high-strength materials to minimize the interior. The degree of deformation of the space maximizes the protection of the occupants in the cockpit. The collapsible car body located in front of and behind the car can not only cope with the impact accident, but also enhance the cockpit protection in all directions, alleviating the secondary impact, which is beneficial to the driver to escape or be saved.
summary:
In today's increasingly developed transportation, the safety performance of automobiles has become more and more concerned by consumers. Whether it is a "breaking" stubborn view or a new standard of "standing", the pursuit of "all-round safety" of automobiles will become a car. The new normal of the family, the new five-star safety performance of Corolla will also provide a positive reference for consumers to choose cars and vehicles. However, we also remind readers that there is no 100% safe vehicle in the world. Don't over-trust your driving skills. At the crucial moment, fasten your seat belt and use the child seat correctly is the real weapon.
