The invention relates to the technical field of automobile parts, and provides a threshold beam collision structure, a frame assembly and a vehicle. An inclined part inclined from inside to outside is arranged at the end part of the doorsill beam; the sliding assemblies are correspondingly arranged at the ends of the doorsill beam at intervals and detachably connected with the side wall at the ends of the doorsill beam. The sliding assembly is provided with a sliding part parallel to the inclined part at intervals. The sliding assembly can be separated from the side wall under the action of external force, and falls outwards from the side wall at the end of the doorsill beam 1 in the mode that the sliding part slides along the inclined part in an attached mode. Both the frame assembly and the vehicle comprise the threshold beam collision structure, and can slide along the inclined part of the end part of the threshold beam through the sliding component when the vehicle is collided, so that the wheel falls off outwards from the side wall at the end part of the threshold beam or is bent outwards from the side wall at the end part of the threshold beam; therefore, the collision impact load borne by the doorsill beam can be reduced, and the relatively serious damage of the collision impact load to a vehicle body is reduced.
本公开涉及汽车部件技术领域,提供了一种门槛梁碰撞结构、车架总成及车辆,前者包括门槛梁和滑移组件;门槛梁端部设有由内向外倾斜的倾斜部;滑移组件间隔对应设置于门槛梁的端部,且与门槛梁端部处的侧围可分离连接;滑移组件具有与倾斜部平行间隔的滑移部;滑移组件能够在外力作用下与侧围分离,并通过滑移部贴沿倾斜部滑动的方式从门槛梁1端部处的侧围向外脱落。该车架总成及该车辆均包括上述的门槛梁碰撞结构,均能够在车辆发生碰撞时,通过滑移组件贴沿门槛梁端部的倾斜部滑动,使得车轮从门槛梁端部处的侧围向外脱落或使得车轮从门槛梁端部处的侧围向外弯折,从而可以减小门槛梁承受的碰撞冲击载荷、降低碰撞冲击载荷对车身造成相对严重的破坏。
