Problems solved by technology
With the increasing number of cars, traffic accidents such as collisions and rear-end collisions are common. Therefore, the safety performance of cars is becoming more and more important. At present, the passive safety protection of vehicles is often in exchange for reducing personal injuries by damaging the front of the car to absorb the impact. When a car At the moment of a collision, the huge inertial force will cause the head or tail of the car to be squeezed and severely deformed. At this time, the bumper cannot achieve the purpose of protecting the car body at all.

The invention relates to the field of automobile collision buffering equipment and relates to an active extending type automobile collision buffering device. The invention aims at solving the problemthat the length of a front longitudinal beam of the traditional automobile is not enough during a collision. According to the active extending type automobile collision buffering device, an energy absorbing device of an automobile is expanded outside the automobile; by mounting one set of telescopic buffering device between an automobile sill and an automobile front bumper, the buffering device and the bumper can extend out of the automobile to improve an energy absorbing space effect by using a manual device or an automatic control device before a collision occurs; and therefore, the impact force during the collision is reduced, and safeties of a driver and an automobile body are protected.
Description
technical field [0001] The invention relates to an active extension type automobile collision buffer device, which belongs to the field of automobile collision buffer equipment. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, cars have become an indispensable means of transportation for people to travel. With the increasing number of cars, traffic accidents such as collisions and rear-end collisions are common. Therefore, the safety performance of cars is becoming more and more important. At present, the passive safety protection of vehicles is often in exchange for reducing personal injuries by damaging the front of the car to absorb the impact. When a car At the moment of a collision, the huge inertial force will cause the head or tail of the car to be squeezed and severely deformed. At this time, the bumper cannot achieve the purpose of protecting the car body at all. Therefore, how to preserv...
