Abstract

The invention discloses a metal / composite material integrated bumper device, which belongs to the technical field of automobile lightweight and collision safety. The bumper device comprises a bumper beam metal outer panel, a bumper beam composite material inner panel, an energy-absorbing box, a composite material inner panel reinforcing rib and a composite material lock buckle. Based on the design concept of lightweight and modularized automobiles, the invention comprehensively utilizes the characteristics of strong metal bearing capacity, high specific strength of composite materials, good impact energy absorption and complex geometry, and adopts advanced direct injection molding and adhesion integration Made by molding process. The integrally formed automobile bumper device has high integration, shortens the assembly process, has good economic benefits, and is easy to popularize. The use of composite materials reduces the weight of the bumper, realizes lightweight, reduces vehicle fuel consumption, reduces exhaust emissions, designs and manufactures a rib structure with good load-bearing capacity, and improves the collision safety of the vehicle bumper.

Description

technical field [0001] The invention relates to a bumper device capable of deforming and absorbing energy during a car collision, in particular to a bumper device integrated with metal / composite materials, which adopts a direct injection molding adhesion integrated molding process, and combines the metal bearing capacity The advantages of high strength, good rigidity, light weight of composite materials, and the ability to form complex geometries form a lightweight and integrated metal and composite material hybrid bumper structure, which belongs to the field of automotive lightweight and crash safety technology. Background technique [0002] Globally, environmental protection and energy crisis are getting more and more attention. It is imperative to reduce the weight of automobiles, save energy and reduce emissions. Automobile lightweight has become an important development direction of the automobile industry. However, it should be noted that the weight reduction of automo...
