The battery system of the electric automobile increases the automobile mass by 250-400 kg, and the requirement for light weight of the electric automobile is more urgent. The automobile anti-collision beam assembly plays an energy absorption role in automobile frontal collision, the steel anti-collision beam is generally used in the anti-collision beam assembly of the existing automobile, and when the requirement can be met in the aspect of collision performance, the mass is large, so that the oil consumption is high, the emission is large, and the automobile control performance is reduced. Compared with the traditional steel, the aluminum alloy material has obvious advantages in density, and the energy absorption of unit mass of aluminum in collision is 2 times of that of steel. Therefore, more and more middle-end and high-end vehicle types, especially new energy vehicles favor the anti-collision beam using the aluminum alloy material. Compared with a steel anti-collision beam, the aluminum alloy anti-collision beam has an obvious light weight effect on the premise of meeting the requirement of the automobile collision performance.

Further, the energy absorption boxes are designed in a wave shape so as to induce the energy absorption boxes to crush and absorb energy during collision.
Furthermore, there are two horizontal strengthening ribs and two vertical strengthening ribs in the anticollision crossbeam, all extend to the other end from one section.
Furthermore, the anti-collision beam, the beam inner reinforcing ribs, the wave-shaped energy absorption box and the mounting bottom plate are designed in an integrated mode, and the anti-collision beam, the beam inner reinforcing ribs, the wave-shaped energy absorption box and the mounting bottom plate are formed by precisely casting an integrated aluminum alloy during production.
The energy-absorbing box of this scheme compares conventional non-wave structure at the conquassation in-process, and the conquassation mode is better, and the energy-absorbing effect is better, compares in the isomorphic energy-absorbing box of steel, and the energy-absorbing effect is also better.
