AI Technical Summary

Technical Problem

Traditional door anti-collision beams are prone to severe deformation and intrusion in side collisions, and their low stiffness makes it difficult to effectively disperse and absorb impact energy.

Method used

Design a side impact protection component for a car door, including an impact plate, first and second impact protection parts, a trapezoidal impact block, a reinforcing strip group, a circular limiting groove and a V-shaped reinforcing part, which is integrally molded to improve structural strength and rigidity, and disperse and absorb impact force.

Benefits of technology

It improves the protective performance of the door in side collisions, prevents excessive intrusion of the door, enhances the stiffness and deformation resistance of key edges, and optimizes material distribution to reduce component weight.

Abstract

This utility model discloses a side impact protection component for an automobile door, comprising: an impact plate, with a first impact part and a second impact part protruding on its upper and lower sides, respectively; staggered trapezoidal impact blocks protruding on the first and second impact parts; reinforcing strips on both sides of the trapezoidal impact blocks; an inwardly extending strip-shaped mounting groove between the first and second impact parts; a circular limiting groove on the strip-shaped mounting groove; a bonding plate on the left side of the impact plate; and an inwardly folded arc-shaped mounting edge on the right side of the impact plate. The right side of the strip-shaped mounting groove extends to one-third of the mounting edge, and a protruding V-shaped reinforcing part is provided on the mounting edge. This utility model achieves efficient dispersion and absorption of impact force by setting trapezoidal impact blocks, a first impact part, and a second impact part, and strengthens key edges using the V-shaped reinforcing part and the arc-shaped mounting edge, thereby improving the overall protective performance of the car door in side collisions.
