Abstract

The invention discloses an anti-collision bar for an automobile body. A core part of the anti-collision bar is made of a particle enhanced foam aluminum-based composite material; an elastic material layer surrounds the core part; a rectangular steel pipe is arranged outside the elastic material layer. An iron-based alloy material fully meets the requirement on external intensity of a product; aluminum-based alloy better ensures that the product is better in impact resistance effect; meanwhile, the mass of the product is reduced.

Description

technical field [0001] The invention relates to an anti-collision strip for an automobile body, belonging to the technical field of auto parts. Background technique [0002] When we drive daily, we will inevitably encounter small scratches and bumps, which will seriously affect the body of our car. If we don’t go out for a long time, it is easy to rust. In order to protect our car models, many car owners Began to install car anti-collision strips for cars, car anti-collision strips are also called protective strips, anti-scratch strips, etc. Prevent the side of the car body from being scratched or bruised by foreign objects, and play a protective role. The existing anti-collision strip has complicated processing technology and poor anti-collision effect. Contents of the invention [0003] An anti-collision strip for an automobile body, the core of which is a particle-reinforced foamed aluminum-based composite material, the core is wrapped with an elastic material layer, ...
