Automobile anti-collision beam structure based on bionic design

Abstract

The invention discloses an automobile anti-collision beam structure based on bionic design. The automobile anti-collision beam structure comprises a transverse beam body and longitudinal beams which are located at the two ends of the transverse beam body. The automobile anti-collision beam structure is characterized in that the internal structure of the transverse beam body is designed according to the structural characteristics of animal segmental appendage, segmental appendage curling, net shape and egg shape, so that when an automobile is collided, the collision force and energy are transmitted and dispersed along a plurality of paths inside the transverse beam body, the transverse beam body and fixing parts thereof act together to sequentially crush and absorb energy, the collision energy is gradually decreased, and then the impact force and energy transmitted to the longitudinal beams and a passenger compartment are reduced. The number of parts as well as welding connecting parts among all parts is reduced, and the whole automobile weight and cost are lowered; by means of the unique bionic structure of the transverse beam body, the effects that the transverse beam body has a high-strength structure and rapidly transmits, decomposes and absorbs the collision energy are achieved; the automobile anti-collision beam structure can be formed at a time, and the assembling complicacy is reduced; and the purpose of the lightweight design of anti-collision beams is truly achieved from fabrication of single structures.

Description

technical field [0001] The invention relates to automobile component technology, in particular to an automobile anti-collision beam structure based on bionic design. Background technique [0002] The anti-collision beam is used as a protective part in the event of a car collision, and its strength is the key to ensuring the safety of the passengers. The anti-collision beams in the prior art have multiple structural designs, but basically adopt the auxiliary parts of the energy absorber to realize safety protection. For example, the patent announcement number is CN104029646B, an anti-collision beam and a car, including a first anti-collision beam, a second anti-collision beam and a base, the base includes a first inner cavity and a second inner cavity, the first inner cavity and the second inner cavity The first anti-collision beam is connected to the first inner cavity to form a piston structure matching the shape of the first inner cavity, and the second anti-collision bea...

AI Technical Summary

Problems solved by technology

At present, the weight and volume of the anti-collision beam assembly commonly used in electric vehicles are relatively large, which is not conducive to the space layout and lightweight design of the vehicle.

If the lightweight effect is obtained by thinning the parts, the strength of the anti-collision beam will be reduced, which is not conducive to the safety performance of the vehicle
