The invention relates to a vehicle and a multi-stage energy absorption structure thereof, the vehicle comprises a floor, a longitudinal beam, a threshold boundary beam, a cross beam and the multi-stage energy absorption structure, the longitudinal beam and the threshold boundary beam extend in the length direction of the vehicle, the threshold boundary beam is arranged on the outer side of the floor in the width direction, the longitudinal beam is arranged below the floor, and the longitudinal beam and the threshold boundary beam are arranged at an interval; the cross beam extends in the width direction of the vehicle and is arranged above the floor, and the end of the cross beam is located above the longitudinal beam. The multi-stage energy absorption structure comprises a first energy absorption piece, a second energy absorption piece and a third energy absorption piece which are independently arranged, the first energy absorption piece is arranged in the doorsill edge beam, the second energy absorption piece is arranged in the interval space between the longitudinal beam and the doorsill edge beam and is connected with the longitudinal beam and the doorsill edge beam, and the third energy absorption piece is connected to the end of the cross beam and the doorsill edge beam. By arranging the multi-stage energy absorption structure, side collision energy can be broken step by step, so that the side collision energy absorption efficiency and the structural stability of the multi-stage energy absorption structure are improved.
本申请涉及一种车辆及其多级吸能结构,车辆包括地板、纵梁、门槛边梁、横梁和多级吸能结构,纵梁和门槛边梁均沿车辆的长度方向延伸,门槛边梁设于地板在宽度方向上的外侧,纵梁设于地板下方,且与门槛边梁间隔设置,横梁沿车辆的宽度方向延伸,横梁设于地板上方,且横梁的端部位于纵梁上方;多级吸能结构包括各自独立设置的第一吸能件、第二吸能件以及第三吸能件,第一吸能件设于门槛边梁内,第二吸能件设于纵梁与门槛边梁之间的间隔空间内,且连接纵梁和门槛边梁,第三吸能件连接于横梁端部和门槛边梁。本申请通过设置多级吸能结构,能够逐级击溃侧面碰撞的能量,从而提高多级吸能结构的侧碰吸能效率和结构稳定性。
