Abstract
A single-piece, lightweight, energy-absorbing, and impact resistant battery tray for a battery enclosure for a vehicle includes a lower floor including an impact resisting structure, upwardly sloping side walls integrally formed with the lower floor, and a peripheral flange integrally formed with the upwardly sloping side walls and including an energy absorbing structure.
Claims18
A battery tray for a battery enclosure for a vehicle, the battery tray comprising:
- a lower floor comprising an impact resisting structure, wherein the impact resisting structure comprises:
- a first layer including continuous fibers embedded in a polymeric matrix;
- a second layer attached to a first side of the first layer and including flame resistant fibers;
- and
- a third layer attached to a second side of the first layer, opposite the first side, and including a fiber-reinforced polymer (FRP) corrugated structure;
- upwardly sloping side walls integrally formed with the lower floor;
- and
- a peripheral flange integrally formed with the upwardly sloping side walls and comprising an energy absorbing structure.
