Vehicle Hood Inner Panel Reinforcement Bead Layout

The reinforcement structure is segmented into multiple directional components: first reinforcement bead extending in the vehicle width direction, second reinforcement bead extending in the vehicle front-rear direction, and third reinforcement bead extending diagonally. This segmentation allows each bead to independently bear loads in specific directions, effectively preventing cavity formation while maintaining overall lightweight design.

The invention transitions from conventional single-direction or two-direction reinforcement to three-dimensional reinforcement by adding the third reinforcement bead that extends diagonally from the stopper contact portion. This multi-dimensional arrangement creates a spatial load distribution network that significantly enhances rigidity without proportionally increasing weight.

Multiple reinforcement functions are merged into a single integrated bead structure. The first, second, and third reinforcement beads are formed as continuous protrusions from the hood inner panel, combining load-bearing, structural support, and deformation prevention functions into one unified reinforcement system rather than separate components.

The reinforcement beads are formed integrally with the hood inner panel through the same molding process, allowing the panel to reinforce itself without requiring additional parts or assembly steps. The beads are self-contained structural features that automatically provide the necessary reinforcement when formed during panel manufacturing.
