Abstract
Example embodiments relate to a vehicle energy absorbing device that includes a primary energy absorbing box and a secondary energy absorbing box, the primary energy absorbing box having a U-shaped cross section with a bottom and a wall extending therefrom, the secondary energy absorbing box being nested inside the primary energy absorbing box. In the event of a collision between a car and a pedestrian, the secondary energy absorbing box of the vehicle energy absorbing device is configured to provide continuous stiffness when the primary energy absorbing box is almost collapsed, so as to protect lower legs of pedestrians and reduce harm thereto. The vehicle energy absorbing device can not only decrease harm to lower legs of pedestrians, but also reduce damage to automobiles as a result of a low-speed collision.
