Ladder honeycomb hood structure for a motor vehicle for pedestrian protection

摘要

A ladder honeycomb hood structure for a motor vehicle for pedestrian protection. The ladder has an inner panel having ten numbers of complete equally sized hexagonal of equal diameter cutout with on side making 10° to the horizontal. A first central ladder cutout formed with a horizontal rib. A second central ladder cutout formed with smaller length of horizontal rib than that of the first ladder above the first central ladder. A third central ladder cutout 4 formed below the first central ladder with horizontal rib, merged with a rear channel, having a bigger length than that of the first central ladder. The hood structure arrangement made in such a way that the hexagonal cutouts equally formed on both sides of the central ladders. A number of unequal size hexagonal cutouts formed in the space between equal size hexagons the and hood side section.

1. A ladder honeycomb hood structure for a motor vehicle for pedestrian protection comprising:
an inner panel having ten complete equally sized first hexagon cut-out portions of equal diameter, each of said first hexagon cut-out portions comprises one side disposed at ten degrees to a horizontal direction; a first central ladder cut-out formed with a first rib, said first rib extending in the horizontal direction and having a first length; a second central ladder cut-out located above the first central ladder cut-out, said second central ladder cut-out formed with a second rib, said second rib having a second length shorter than the first length of the first rib, said second rib extending in the horizontal direction; a third central ladder cut-out located below the first central ladder cut-out, said third central ladder cut-out formed with a third rib, said third rib having a third length longer than the first length of the first rib, said third rib extending in the horizontal direction; wherein the first, second, and third ribs of the central ladder cut-outs are disposed to resemble a ladder shape, defining a central ladder; said hood structure is arranged such that said first hexagon cut-out portions are symmetrically formed on both sides of said central ladder; and a plurality of unequally sized second hexagon cut-out portions are formed in a space between the first hexagons and a hood side section.
