Minicar impact-proof beam energy absorption box capable of controlling impact energy absorption and residual deformation

Abstract

The invention relates to a minicar impact-proof beam energy absorption box capable of controlling impact energy absorption and residual deformation, which is used for solving the problem of the energy absorption of a front impact-proof beam and comprises a transverse beam and energy absorption boxes symmetrically arranged on both sides of the transverse beam, wherein the improved energy absorption boxes are provided with bulged and concave guide tendons regularly distributed; the bulged guide tendons and the concave guide tendons are alternately arranged on the side walls of the energy absorption boxes; the positions of the bulged and the concave guide tendons on the two relative side walls of the energy absorption boxes are corresponding; and the positions of the bulged and the concave guide tendons on the two adjacent side walls of the energy absorption boxes are corresponding. The invention has the advantages that the guide tendons regularly distributed are successively squashed and absorb energy when the front impact-proof beam of an automobile is impacted through the optimization design of the guide tendons arranged on the energy absorption boxes, and the front impact-proof beam presents an S-shaped squashing type when deforming; the energy absorption can be satisfied, and the height of the energy absorption boxes after deforming can be effectively overlaid and supported at the same time; the residual deformation of the energy absorption boxes after squashing can be guaranteed; and the deformation mode of the energy absorption box basically coincide to the expected design through CAE analysis and test confirmation.

Problems solved by technology

Most of the existing energy-absorbing boxes have guide ribs with irregular structures on the box body. It is difficult to control the deformation process and energy absorption of the structure of the energy-absorbing box when such guide ribs collide. Usually, when the energy is absorbed for a long time, the The amount of crushing is very large, and when reducing the amount of guiding ribs to reduce the amount of crushing, the energy absorption is reduced, and it is difficult to achieve a balance
