The invention relates to the technical field of vehicles, in particular to a threshold beam assembly, a vehicle body assembly and a vehicle. The invention aims to solve the problem that the doorsill beam cannot give consideration to battery pack protection and light weight at the same time. In order to achieve the purpose, the doorsill beam assembly comprises a beam body which is an extrusion part, the beam body is in a long strip shape, and a plurality of containing cavities are formed in the beam body in the length direction; and the structural reinforcer is in a long strip shape, the length of the structural reinforcer is smaller than that of the beam body, and the structural reinforcer is arranged in one of the multiple containing cavities and connected with the beam body. According to the doorsill beam assembly, the structural reinforcing part is arranged in one containing cavity of the beam body, and the length of the reinforcing part is smaller than that of the beam body, so that protection of the battery pack and light weight of the doorsill beam can be both considered.

    本发明涉及车辆技术领域,具体涉及一种门槛梁组件、车身总成及车辆。本申请旨在解决门槛梁无法同时兼顾电池包保护和轻量化的问题。为此目的,本申请的门槛梁组件包括:梁主体,梁主体为挤压件,梁主体呈长条形且内部沿长度方向形成有多个容纳腔;结构加强件,结构加强件呈长条形且其长度小于梁主体的长度,结构加强件设置于多个容纳腔中的一个并且与梁主体连接。本申请的门槛梁组件,通过在梁主体的一个容纳腔内设置结构加强件,且加强件长度小于梁主体的长度,可以兼顾电池包的保护和门槛梁的轻量化。
