Engine room force transfer structure dealing with automobile small offset crashes

Abstract

The invention relates to an engine room force transfer structure dealing with automobile small offset crashes. The structure comprises a front anti-collision beam assembly, an engine room longitudinalbeam assembly and a force transfer component which is positioned and connected to the engine room longitudinal beam assembly and corresponds to the front anti-collision beam assembly; the front anti-collision beam assembly comprises an anti-collision beam and an energy absorption box; the structure is characterized in that the force transfer component is formed by connecting a stress component, asupporting component and a main force transfer component, and the whole structure is in a triangular shape. When small offset crashes of automobiles happen, the engine room longitudinal beam sufficiently participates in deformation and energy absorption, and the automobile body kinetic energy is lowered; a power assembly is forced to move in the reverse direction of the crash side, crash impact force on the crash side is timely and effectively transferred to the non-crash side through the power assembly, the longitudinal crash impact force of the automobile body is greatly reduced, the passenger compartment deformation amount is reduced, and life safety of passengers is ensured.

Description

technical field [0001] The invention relates to an automobile body, in particular to a force transmission structure of a cabin for dealing with small offset collisions of automobiles. Background technique [0002] When a car collides head-on with a collision object, the deformation of the main load-bearing structure at the front of the vehicle is required to fully absorb the energy generated by the collision, so as to protect the occupants of the car to the greatest extent. The anti-collision beam assembly and the longitudinal beam of the cabin in the traditional car body structure are designed with reasonable strength to cope with the collision situation when the overlapping area between the vehicle and the collision object is large. However, when the width of the overlapping area between the vehicle and the collision object is less than 25% of the width of the vehicle body, the anti-collision beam assembly and the cabin longitudinal beam cannot fully participate in such a ...

AI Technical Summary

Problems solved by technology

Vehicles tested for the above-mentioned evaluation items are often affected by the chassis and cabin side beams to the passenger compartment because the anti-collision beams and cabin longitudinal beams do not fully participate in the collision energy absorption, and the huge impact force is not effectively weakened, resulting in occupant damage. Huge deformation of the cabin

In this case, the car body and the dummy will get a poor evaluation result, and the overall evaluation result of the small offset collision will also be difficult for consumers to accept, and the safety performance of this model will be questioned
