Description

Anti-collision beam structure capable of improving small-offset collision safety Technical Field The utility model relates to the technical field of automobile anti-collision, in particular to an anti-collision beam structure capable of improving the safety of small offset collision. Background With the gradual increase of the holding quantity of automobiles, the number of accidents of the automobiles is also gradually increased, and the safety of the automobiles in the collision process is an increasingly focused problem. In such a context, the middle guard led to a 25% small offset collision in 2017. When the vehicle collides with the front face, the contact area of the small offset collision and the barrier is only 25 percent of the width of the vehicle, so that the longitudinal beam is basically avoided, the energy during collision is almost transmitted to the passenger cabin without being blocked, the front suspension, wheels and steering mechanism of the vehicle can be displaced backwards, and the vehicle can possibly invade the passenger cabin to cause injury to passengers in severe cases. Based on the working condition, the anti-collision beam is required to have enough strength, and the existing anti-collision beam structure mostly adopts the whole size to thicken or extends the width of the anti-collision beam to meet the requirement of small offset collision, so that the weight of the vehicle body is increased, but the effect is general. Disclosure of utility model The utility model is used for overcoming the defects of the prior art and providing an anti-collision beam structure capable of improving the safety of small offset collision so as to solve the problems mentioned in the background art.
