Automotive collision energy absorbing device

The utility model discloses an automotive collision energy absorbing device, which comprises an energy absorbing beam, a front cross beam and a longitudinal engine compartment beam. The energy absorbing beam is of a wedge-shaped structure with the front part smaller than the rear part, an upper plate and a lower plate are arranged on the energy absorbing beam, wherein the upper plate is provided with a weight relief collapsing hole and an upper collapsing rib, and the lower plate is provided with a lower collapsing rib. The majority of the energy generated in collision can be absorbed through collapsing deformation. The utility model can achieve the uniform energy-absorbing effect within a short distance, thereby ensuring that sufficient living space can be provided for passengers in the compartment, and realizing the function of protecting the safety of the passengers. Moreover, the utility model has the advantages of light weight, simple structure and low cost.
