AI Technical Summary

Technical Problem

In the existing technology, the car door is easily pushed significantly into the vehicle interior during a side collision, causing the risk of injury to the occupants. In addition, the overlapping size of the traditional door anti-collision beam is difficult to adjust arbitrarily, and it is impossible to effectively reduce the intrusion of the car door.

Method used

A longitudinal door anti-collision beam is designed with a groove perpendicular to its longitudinal extension direction and is connected to the vehicle door by mechanical fixation. The groove forms a large axial resistance torque to resist lateral impact and reduce door intrusion.

Benefits of technology

Without increasing materials and costs, the dimensional stability and side impact resistance of the door are improved, the intrusion of the door during side collision is reduced, and the safety of the passengers is improved.

Abstract

The invention relates to a door impact beam (20) for reducing door intrusion in the event of a lateral impact of a motor vehicle, the door impact beam (20) having an elongate shape and being arranged on a door body (10) of a door of the motor vehicle in the longitudinal direction (120) of the motor vehicle by means of at least one component of the longitudinal extension direction (23) thereof, and wherein the door impact beam (20) is arranged on the door body (10) of the door of the motor vehicle in the longitudinal direction (120) of the motor vehicle. The door impact beam (20) forms a surface in a plane in at least one of the end regions (21, 22) of the door impact beam (20) and has at least one recess (31, 32) in the surface (40), which recess extends perpendicular to the longitudinal extension direction (23) of the door impact beam (20). The invention also relates to a vehicle door equipped with the door impact beam and a motor vehicle having the vehicle door.
