Problems solved by technology

The inside of the main beam is provided with a connecting plate connecting the outer plate of the main beam and the mounting plate of the main beam. The overall cross-sectional shape of the main beam is mostly in the shape of "mesh" or "field". Alloy main girders are not good in terms of deformation stiffness and bending resistance, especially when the collision force acts on the non-connected part of the outer plate of the main girder and the connecting plate, the absorption efficiency of the main girder to the collision energy is lower

Abstract

The invention provides an aluminum alloy automobile anti-collision beam, and relates to the field of anti-collision beams. The aluminum alloy automobile anti-collision beam comprises two fixed bases, first mounting positioning holes are fixedly formed around one side of each fixed base; buffer box bodies are fixedly connected to one side of each fixed base, the same metal cross beam is fixedly connected to the sides, away from the fixed bases, of the two buffer box bodies, and the metal cross beam is arranged to have a radian; a gravity groove is formed in the middle end of the side, away from the fixed bases, of the metal cross beam, a cavity area formed between the inner walls of the metal cross beam is a cross beam inner cavity, cross beam reinforcing ribs are arranged in the cross beam inner cavity, and the cross beam reinforcing ribs are shaped like a Chinese character 'gong'. The aluminum alloy automobile anti-collision beam has the advantage of being high in anti-collision performance.

Description

technical field [0001] The invention relates to the technical field of anti-collision beams, in particular to an aluminum alloy automobile anti-collision beam. Background technique [0002] Anti-collision beams, as a common safety protection device on automobiles, are widely used in various vehicles. Anti-collision beams are mainly used to absorb the collision energy during low-speed collisions of vehicles, and minimize the damage to the body caused by the impact force. [0003] The aluminum alloy anti-collision beam in the prior art mainly includes a main beam, an energy-absorbing box and a longitudinal beam, and the main beam is connected to the longitudinal beam through the energy-absorbing box. The inside of the main beam is provided with a connecting plate connecting the outer plate of the main beam and the mounting plate of the main beam. The overall cross-sectional shape of the main beam is mostly in the shape of "mesh" or "field". Alloy girders are not good in terms...
