The invention discloses a threshold beam, a threshold assembly and a vehicle, the threshold beam comprises a first cavity and a second cavity which are adjacently arranged, the first cavity is arranged close to the interior of the vehicle, the second cavity is arranged close to the exterior of the vehicle, and the upper wall and/or the lower wall of the first cavity extends out of the second cavity in the Z-axis direction; an acute angle is formed between the upper wall and/or the lower wall of the first cavity and the inner side wall of the first cavity. The threshold beam can be deformed by guiding collision, the force transmission path is coherent and efficient, the energy absorption effect is better, the collision force is effectively dispersed, and the safety performance is improved.
本发明揭示了门槛梁、门槛总成以及车辆,门槛梁包括邻接设置的第一腔体和第二腔体,所述第一腔体靠近车辆的内部设置,所述第二腔体靠近车辆的外部设置,所述第一腔体的上壁和/或下壁沿Z轴方向延伸出所述第二腔体,所述第一腔体的上壁和/或下壁相对于所述第一腔体的内侧壁形成锐角。本发明实现了门槛梁能够通过引导碰撞变形,传力路径连贯高效,吸能效果更好,有效分散碰撞力,提升安全性能。
