AI Technical Summary
Existing automotive impact absorption structures are difficult to stably generate axial flattening deformation during a collision, resulting in low energy absorption efficiency.
An automotive impact-absorbing structure employs a first component and a second component made of metallic material, wherein the second component has an axial length of 15% to 75% of the first component and satisfies a specific distance and radius of curvature relationship, and the joint line extends along the circumferential or inclined direction of the first component.
It improves the energy absorption efficiency of the vehicle's impact absorption structure, ensures stable axial flattening deformation during a collision, and enhances the energy absorption performance of the vehicle's interior.
