Cellular Vehicle Impact Structure for Lightweight Energy Absorption

The impact protection structure is divided into multiple individual sections arranged in a cellular pattern. Each section can deform independently during impact, distributing the impact forces across multiple elements rather than requiring a single heavy structure to bear the entire load. This segmentation allows the structure to achieve adequate strength through distributed load-bearing capacity while reducing overall material usage and weight.

The patent employs a cellular structure composed of multiple sections with specific geometric configurations that combine different structural properties. The cellular arrangement creates a composite-like behavior where the interconnected sections work together to provide both strength and energy absorption capabilities, achieving high impact protection with reduced material density compared to solid conventional structures.

By segmenting the structure into multiple lightweight cellular sections, the design achieves adequate strength through distributed load-bearing rather than relying on heavy monolithic components. Each section uses minimal material while contributing to the overall structural integrity, enabling cost-effective production with reduced material costs and lower weight.

The cellular sections incorporate curved surfaces and rounded geometries that efficiently distribute stress during impact. The curved surfaces of the hexagonal or polygonal sections redirect impact forces along optimized stress paths, enhancing the strength-to-weight ratio and allowing lighter materials to provide sufficient protection capability.

The cellular segmentation creates multiple load paths and deformation zones that enhance structural reliability during impact. When impact occurs, the distributed cellular structure provides redundant load-bearing pathways, ensuring that failure of individual sections does not compromise overall protection. This multi-path load distribution maintains reliable impact protection even with lightweight materials.

The cellular structure is designed to deform dynamically during impact, with sections progressively collapsing or bending in a controlled sequence. This dynamic response allows the structure to absorb impact energy through progressive deformation rather than rigid resistance, maintaining reliability by adapting to impact forces while keeping the structure lightweight.

The segmented cellular design allows different parts of the structure to exhibit different mechanical behaviors during impact. The cellular walls provide penetration resistance through their geometric configuration and material properties, while the joints and connections between sections allow controlled deformation and energy absorption. This segmentation enables simultaneous achievement of rigidity for penetration prevention and flexibility for energy management.

Different regions of the cellular structure are designed with locally optimized properties: the cellular walls are configured to resist penetration through appropriate thickness and geometric reinforcement, while the connection zones between sections are designed to deform preferentially for energy absorption. This local differentiation of structural qualities allows the overall structure to simultaneously achieve penetration resistance and deformation capability.
