The collision energy absorption assembly structure comprises an anti-collision beam and a plurality of energy absorption structures, the energy absorption structures are arranged on the upper side and the lower side of the anti-collision beam at intervals correspondingly, and the two ends of each energy absorption structure are connected with the side face of the anti-collision beam and the side wall of the threshold correspondingly; energy absorption areas used for containing the energy absorption structures are formed between the upper side of the anti-collision beam and the top of an inner cavity of the threshold and between the lower side of the anti-collision beam and the bottom of the inner cavity of the threshold correspondingly, extrusion areas are formed on the upper side and the lower side of the anti-collision beam correspondingly, and the extrusion areas are located at the positions deviating from the energy absorption areas; when the side face of the automobile body is collided, the anti-collision beam is squeezed to enable the squeezing area to move to the energy absorption area, so that the space of the energy absorption area in the vertical direction is reduced, and the squeezing area squeezes the energy absorption structure to enable the energy absorption structure to deform. The anti-collision beam resists impact, deformation of the energy absorption structure further buffers and absorbs energy, and the impact resistance of the threshold is improved. The invention can be widely applied to the technical field of automobile parts.

    本申请公开了一种应用于车身门槛的碰撞吸能总成结构及汽车,碰撞吸能总成结构包括防撞梁和多个吸能结构,防撞梁的上侧和下侧分别间隔布置多个吸能结构,吸能结构的两端分别连接防撞梁的侧面和门槛的侧壁;防撞梁的上侧与门槛的内腔的顶部之间以及防撞梁的下侧与门槛的内腔的底部之间分别形成有用于容纳吸能结构的吸能区,防撞梁的上侧和下侧分别形成有挤压区,挤压区处于偏离吸能区的位置;当车身侧面受到碰撞时,防撞梁受挤压而使挤压区移动至吸能区,以使吸能区在竖直方向上的空间缩小,且挤压区挤压吸能结构,以使吸能结构变形。防撞梁抵抗冲击以及吸能结构变形进一步缓冲吸能,提高门槛的抗冲击能力。本申请可广泛应用于汽车配件技术领域。
