The invention provides a side collision protection structure for a vehicle and a vehicle bottom structure. The side collision protection structure is suitable for being connected between a seat cross beam and a doorsill and comprises a body, and the body is provided with a first connecting part used for being connected to the seat cross beam, a second connecting part used for being connected to the doorsill and a third connecting part suitable for being connected to a vehicle seat guide rail; the crumple part is arranged between the second connecting part and the third connecting part; the crumple part is configured to crumple and deform when subjected to transverse impact so as to disperse impact force transmitted to the third connecting part. According to the side collision protection structure, the connecting structure strength needed between the seat cross beam and the doorsill is provided through the body, normal use of the vehicle bottom structure is guaranteed, and meanwhile impact force is absorbed and dispersed through a small amount of displacement when the side face of a vehicle body is subjected to transverse impact or collision through the crumple part; damage of impact force to vehicle seats and power battery packs is reduced, and personal safety of passengers in a vehicle is protected.
本公开提供一种用于车辆的侧面碰撞防护结构以及车辆底部结构。侧面碰撞防护结构适于连接在座椅横梁和门槛之间,并包括:本体,所述本体设有用于连接至座椅横梁的第一连接部、用于连接至门槛的第二连接部,以及适于连接车辆座椅导轨的第三连接部;溃缩部,所述溃缩部布置于第二连接部和第三连接部之间;所述溃缩部配置为在受到横向冲击时溃缩变形,以分散传递至第三连接部的冲击力。本公开的侧面碰撞防护结构通过本体提供座椅横梁和门槛之间所需的连接结构强度,保证车辆底部结构的正常使用,同时通过溃缩部在车身侧面受到横向冲击或碰撞时以少量位移将冲击力吸收分散,减小冲击力对例如车辆座椅以及动力电池包的破坏,保护了车内乘员人身安全。
