Abstract

The invention discloses a composite bumper beam assembly, and belongs to the technical field of vehicles. The composite bumper beam assembly comprises a composite beam; the composite beam comprises abeam body and a rib body; the beam body is provided with a containing cavity and made of composites with continuous fibers; and the rib body is of a grid-shaped structure, and is arranged in the containing cavity, connected with the beam body and made of composites with discontinuous fibers. According to the composite bumper beam assembly, the beam body serves as a main body of the composite beamand is formed by the composites with the continuous fibers, and lightweight design of vehicle bodies is facilitated while the anti-collision property of the composite bumper beam assembly is improved;the grid-shaped rib body is made of the composites with the discontinuous fibers, arranged in the containing cavity and connected with the beam body; and after the beam body is collided, the grid-shaped rib body can further achieve the impact buffering effect, and thus the overall buffering property of the composite bumper beam assembly is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a composite material bumper beam assembly. Background technique [0002] The front and rear ends of the car are fitted with bumper beam assemblies. The bumper beam assembly plays the role of absorbing and mitigating external impact, and protecting the safety of the vehicle body and occupants. [0003] In the prior art, the automobile bumper crossbeam assembly generally includes a crossbeam and a collision buffer, which is connected with the vehicle body. On both sides of the crossbeam, the crossbeam distributes the energy generated by the collision to the two collision buffers as evenly as possible, so that the energy can be absorbed by the collision buffer to the maximum extent, and the collision force is evenly transmitted to other energy-absorbing parts. [0004] However, in the prior art, the beam is generally made of metal, which is not conducive to the lightweight des...
