The invention provides a threshold stiffening beam assembly, a threshold beam and a vehicle, and belongs to the technical field of vehicles. The sill stiffening beam assembly includes a sill stiffening beam and a support. The doorsill stiffening beam comprises a bottom plate, a top plate and a plurality of vertical plates, and a cavity is formed between every two adjacent vertical plates. The supporting piece is located at the end of the doorsill stiffening beam and comprises at least one supporting boss, and the supporting bosses extend into the cavity and abut against the vertical plates on the two sides. When the doorsill stiffening beam assembly is installed on the doorsill inner plate, the connecting piece penetrates through the supporting boss and the vertical plates on the two sides of the supporting boss and is connected with the doorsill inner plate. Due to the fact that the connecting piece penetrates through the at least two vertical plates, impact force borne by the doorsill reinforcing beam can be dispersed to be borne by the multiple vertical plates under the working condition of small-offset frontal collision, the doorsill reinforcing beam is not prone to being torn by the connecting piece, the doorsill beam can play a role in abutting against a barrier, the invasion amount of an A column of a vehicle into a cab is small, and the safety of the vehicle is improved. And the safety performance of the vehicle is improved.
本公开提供了一种门槛加强梁组件、门槛梁和车辆,属于车辆技术领域。门槛加强梁组件包括门槛加强梁和支撑件。门槛加强梁包括底板、顶板和多个竖板,相邻两个竖板之间具有腔体。支撑件位于门槛加强梁的端部,支撑件包括至少一个支撑凸台,支撑凸台伸入腔体,并与两侧的竖板相抵。当门槛加强梁组件安装在门槛内板上时,连接件穿过支撑凸台和支撑凸台两侧的竖板并与门槛内板连接。由于连接件穿过至少两个竖板,所以,在小偏置正面碰撞工况下,门槛加强梁受到的冲击力,会分散至由多个竖板承受,使得门槛加强梁不易被连接件撕裂,门槛梁能够起到顶住壁障的作用,车辆的A柱侵入驾驶舱的侵入量较小,提高了车辆的安全性能。
