Anti-collision structure device at front end of automobile

Abstract

The invention discloses an anti-collision structure device at a front end of an automobile. The anti-collision structure device comprises a front anti-collision beam, two absorption boxes, front longitudinal beams in one-to-one correspondence with the absorption boxes and a supporting plate. Each front longitudinal beam is of a closed dodecagon frame structure formed by combining four U-shaped frames, and the cross section of each front longitudinal beam has a hollow cross frame structure; the two absorption boxes are fixedly arranged on the inner sides of the two ends of the front anti-collision beam respectively, one end of each front longitudinal beam is fixedly connected to the front anti-collision beam through one absorption box, and the other end of the front longitudinal beam is fixedly connected to the supporting plate. According to the anti-collision structure device, the mass of an automobile body is reduced. According to the device, the section shape of the front longitudinal beam is changed, a more reasonable layout scheme is selected, the dodecagon has a better collision energy absorption effect by being compared with a quadrangle, a hexagon and an octagon, the anti-collision performance of a vehicle can be enhanced; and casualties of passengers are reduced as much as possible when traffic accidents happen.

Description

technical field [0001] The application relates to an anti-collision structure device for the front end of an automobile. Background technique [0002] With the rapid increase in the number of passenger cars, the number of casualties caused by car collisions continues to increase. The frontal collision safety performance design of automobiles has been highly valued by the automobile industry. The so-called frontal collision is that the head of the vehicle directly collides with an obstacle. There are three common types, namely 100% rigid barrier collision, 40% overlap offset frontal collision and 25% overlap offset frontal collision. Here, 100% rigid barrier collision is used for research. When a car crashes, the body structure deforms first, and in a very short time, passengers interact with the car's restraint systems. Reasonable optimized design of the body structure can maximize the deformation and energy absorption of the anti-collision structure, thereby providing st...

Problems solved by technology

At present, the design of energy-absorbing mechanisms in the automotive industry is far from reaching the upper limit. Traditional energy-absorbing mechanism designs and metal materials no longer have performance advantages. The optimization of its materials and structures still needs further improvement.
