Reinforced Battery Box Bearing Plate for Impact Buffering

The patent applies local quality by adding reinforcing members with cavities at specific locations on the bearing plate rather than uniformly thickening the entire plate. The cavities are strategically positioned to provide local reinforcement where impact forces are most likely to occur, maintaining thin overall plate thickness while enhancing specific areas for improved impact resistance.

The patent employs composite material structure by combining the bearing plate with reinforcing members that have cavity structures. This composite design integrates two different structural elements - the thin base plate and the reinforced protruding portions with cavities - to achieve both space efficiency and enhanced mechanical strength simultaneously.

Instead of uniformly increasing the bearing plate thickness throughout, the patent applies local quality by adding reinforcing members with cavities only at specific critical locations. This localized reinforcement approach provides enhanced impact resistance where needed while maintaining thin plate thickness in non-critical areas, thus minimizing overall space occupation.

The patent transitions from a two-dimensional uniform thickness approach to a three-dimensional structure by adding protruding portions with cavities. This dimensional change allows the reinforcing members to extend outward from the plate surface, providing enhanced strength without increasing the in-plane dimensions or overall space occupation of the battery box.

The patent applies merging by integrating the reinforcing members as integral parts of the bearing plate structure rather than separate attachable components. The reinforcing members are formed as protruding portions directly from the plate material, combining the functions of the base plate and reinforcement elements into a single unified structure, thereby reducing assembly complexity.

The patent employs parameter changes by modifying the geometric parameters of the bearing plate structure - specifically by adding cavities within the protruding portions of the reinforcing members. This geometric parameter modification (introducing void spaces) enhances the mechanical properties and energy absorption capacity without requiring additional materials or complex multi-component assemblies.
