The invention relates to a collision protection assembly and a commercial vehicle. The collision protection assembly comprises an energy absorption module which comprises a plurality of energy absorption units, and each energy absorption unit comprises a first energy absorption piece and at least two second energy absorption pieces; one ends of all the second energy-absorbing pieces are intersected, and the other ends of all the second energy-absorbing pieces extend radially; the first energy absorption piece is supported at the intersection of all the second energy absorption pieces in a deformable mode in the first direction; every two adjacent energy absorption units are in force transmission connection through at least part of the second energy absorption pieces of the energy absorption units. When one energy absorption unit or multiple energy absorption units of the collision protection assembly are impacted, every two adjacent energy absorption units are in force transmission connection through at least part of the second energy absorption pieces of the energy absorption units, and the impacted energy absorption units can transmit impact force to the adjacent energy absorption units through the second energy absorption pieces of the energy absorption units; and the impact force continues to be transmitted to other adjacent energy absorption units through the energy absorption unit, so that dissipation and conduction of the collision load are achieved, and local crushing caused by instability of the protection assembly is avoided.
本申请涉及一种碰撞防护总成及商用车。该碰撞防护总成,包括:吸能模块,包括多个吸能单元,每一吸能单元包括第一吸能件和至少两个第二吸能件;全部第二吸能件的一端相交设置,另一端呈辐射状延伸;第一吸能件沿第一方向可形变地支撑于全部第二吸能件的相交处;其中,每相邻的两个吸能单元之间通过自身的至少部分第二吸能件力传递连接。当碰撞防护总成的一个吸能单元或多个吸能单元受到冲击,由于每相邻的两个吸能单元之间通过自身的至少部分第二吸能件力传递连接,受冲击吸能单元能够通过自身的第二吸能件将冲击力传递至相邻吸能单元,并由该吸能单元继续传递至其他相邻吸能单元,从而实现碰撞载荷的耗散和传导,避免防护总成失稳造成局部压溃。
