The present invention provides a vehicle energy absorbing device, which comprises a primary energy absorbing box (2) and a secondary energy absorbing box (5), said primary energy absorbing box (2) having a U-shaped cross section with a bottom (24) and a wall (25) extending therefrom, said secondary energy absorbing box (5) being nested inside said primary energy absorbing box (2). In the crash of a car with a pedestrian, said secondary energy absorbing box (5) of the vehicle energy absorbing device according to the present invention can provide continuous stiffness when said primary energy absorbing box (2) is nearly collapsed, so as to protect lower legs of pedestrians and reduce harms to legs of pedestrians. The vehicle energy absorbing device of the present invention can meet the requirements of both GB/T24550-2009 and GB 17354. It can not only decrease harms to lower legs of pedestrians, but also reduce damages to automobiles as a result of low-speed crash. |
