The invention discloses a rear anti-collision beam assembly and a vehicle, the rear anti-collision beam assembly comprises a rear anti-collision beam and a plurality of energy absorption boxes, the plurality of energy absorption boxes are connected between a vehicle body rear floor and the rear anti-collision beam, each energy absorption box comprises a first shell and a second shell, the first shell and the second shell are matched to define an energy absorption cavity, and the energy absorption cavities are communicated with the first shell and the second shell. In the height direction of the vehicle, the first shell and the second shell are in sliding fit so as to be used for adjusting the sectional area of the energy absorption cavity in the height direction. The rear anti-collision beam assembly and the energy absorption box are of a split structure, in this way, the sectional area of the energy absorption cavity in the height direction of the vehicle can be adjusted through sliding fit of the first shell and the second shell, and therefore the rear anti-collision beam assembly can have certain adaptability to the tail shape change of the vehicle, a mold does not need to be developed again, and the cost is reduced. Therefore, the universality of the rear anti-collision beam assembly is better, the development period is shortened, and the cost is reduced.
本发明公开了一种后防撞梁组件和车辆,所述后防撞梁组件,包括:后防撞梁,多个吸能盒,多个所述吸能盒连接于车身后地板与所述后防撞梁之间,且所述吸能盒包括第一壳体和第二壳体,所述第一壳体和所述第二壳体配合以限定出吸能腔,其中,在车辆的高度方向上,所述第一壳体与所述第二壳体滑动配合以用于调节所述吸能腔在所述高度方向上的截面积。本发明的后防撞梁组件,吸能盒构造为分体式结构,这样,能够通过第一壳体和第二壳体的滑动配合来调节吸能腔在车辆的高度方向上的截面积,从而使得后防撞梁组件能够对车辆的尾部造型变化具有一定的适应性,不需重新开发模具,这样,能使后防撞梁组件的泛用性更好,且利于缩短开发周期以及降低成本。
