Crash Beam Support Structure for Dual-Speed Impact Performance

The patent applies local quality by adding a beam support structure specifically at the connecting part between the crash beam body and crash box, rather than reinforcing the entire crash beam globally. This localized reinforcement targets the critical stress concentration area, improving crash performance where needed most while avoiding unnecessary material and cost increases in other areas.

The beam support is divided into a first part connected to the crash box and a second part connected to the crash beam body, with the parts being perpendicular to each other. This segmentation allows the reinforcement structure to adapt to the complex stress distribution at the connecting part, providing effective support while using less material than a solid global reinforcement would require.

By concentrating the reinforcement at the specific location of the connecting part rather than throughout the entire structure, the patent improves crash performance with minimal additional structural complexity. The beam support is a simple L-shaped component that integrates easily into the existing crash beam structure.

Instead of adding complex reinforcement throughout the entire crash beam structure, the patent inverts the approach by adding a simple localized support element at the critical connecting part. This inverted thinking - focusing on the specific weak point rather than the whole structure - achieves better crash performance with less complexity.
