Abstract
An impact absorbing system includes a first rocker panel and a second rocker panel spaced from the first rocker panel, a housing including a bottom extending between the first and second rocker panels and a side extending from the bottom, and an energy absorber that is deformable relative to the side and defines a repeating pattern of cells. The energy absorber is bonded to the side between the side and the first rocker panel and each cell has a central axis transverse to the side.
Claims18
An impact absorbing system comprising:
- a first rocker panel and a second rocker panel spaced from the first rocker panel;
- a housing including a bottom extending between the first and second rocker panels and a side extending from the bottom;
- and
- an energy absorber that is deformable relative to the side and defines a repeating pattern of cells;
- wherein the energy absorber is bonded to the side between the side and the first rocker panel and each cell has a central axis transverse to the side;
- wherein each cell includes a cell wall extending along the central axis from an exposed end to a bonded end directly bonded to the side.
A battery support comprising:
- a housing including a bottom and a side extending from the bottom, the side presenting an inner surface and an outer surface, the housing being configured to receive a battery for an electric vehicle at the inner surface;
- and
- an energy absorber that is deformable relative to the side and defines a repeating pattern of cells;
- wherein the energy absorber is bonded to the outer surface of the side and each cell has a central axis transverse to the outer surface;
- wherein each cell includes a cell wall extending along the central axis from an exposed end to a bonded end directly bonded to the side;
- wherein each cell has a side length perpendicular to the central axis, and each cell wall has a wall thickness, the ratio of the side length to the wall thickness being 170-190 for each cell;
- wherein each cell has a length of 50 mm along the central axis.
A vehicle comprising:
- a frame;
- a first rocker panel and a second rocker panel spaced from the first rocker panel, the first rocker panel and the second rocker panel being supported by the frame;
- a housing supported by the frame and including a bottom extending between the first and second rocker panels and a side extending from the bottom;
- and
- an energy absorber that is deformable relative to the side and defines a repeating pattern of cells;
- wherein the energy absorber is bonded to the side between the side and the first rocker panel and each cell has a central axis transverse to the side;
- wherein the cells each include a cell wall extending along the central axis from an exposed end to a bonded end directly bonded to the side.
