Crash box, anti-collision beam and electric automobile

Abstract

The invention provides a crash box, an anti-collision beam and an electric automobile and belongs to the field of vehicle engineering. The crash box comprises a box body extending in a first preset direction; the cross section of the box body is of octagonal shape; the cross section of the box body is a plane perpendicular to to the first preset direction; a plurality of crumple structures are arranged on the box body; the plurality of crumple structures are arranged in the first preset direction at intervals; and each crumple structure comprises an indentation and a crumple hole on the same cross section. The anti-collision beam comprises the crash box. The automobile comprises the anti-collision beam. The crash box has the advantages that the energy absorption effect is good and the protection performance is strong. The anti-collision beam has the advantages that the anti-collision performance is excellent and the safety performance of the electric automobile can be effectively improved. The electric automobile has the advantages that the safety performance is excellent and life safeties of drivers and passengers can be effectively protected.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to an energy-absorbing box, an anti-collision beam and an electric vehicle. Background technique [0002] In recent years, with the aggravation of environmental pollution, pollution control has become the main topic of contemporary society. In response to the troubles of large pollution sources such as electric vehicle exhaust emissions, new energy electric vehicles have emerged as the times require and will become the darling of the electric vehicle industry. As a new energy electric vehicle, electric vehicles have many characteristics such as energy saving and environmental protection, and are one of the main directions for the development of new energy electric vehicles. [0003] However, the energy-absorbing box of the existing electric vehicle adopts the original structure of the traditional automobile, and the energy-absorbing box of the original structure has the defects of...
