The invention discloses a doorsill beam assembly and a vehicle, the doorsill beam assembly comprises a doorsill beam, the doorsill beam comprises a doorsill outer plate and a doorsill inner plate, and the doorsill outer plate and the doorsill outer plate are buckled and connected to form a doorsill beam cavity; the first reinforcing assembly comprises a first reinforcing plate and a first supporting plate, the first reinforcing plate is connected with the doorsill outer plate, at least part of the first reinforcing plate is arranged in the doorsill beam cavity, and at least part of the first reinforcing plate and at least part of the doorsill outer plate are arranged in a spaced mode; the first supporting plate is connected with the first reinforcing plate, and at least part of the first supporting plate and at least part of the first reinforcing plate are arranged at intervals to form an energy absorption cavity. By arranging the first reinforcing assembly in the threshold beam, the defects that the side impact performance of the whole vehicle is insufficient and the threshold strength is insufficient can be overcome, the problem that the stress deformation amount is large can be solved, and therefore the rigidity, strength, maintenance, collision and NVH performance of the vehicle can be improved.
本发明公开了一种门槛梁总成和车辆,门槛梁总成包括:门槛梁,门槛梁包括门槛外板和门槛内板,门槛外板和门槛外板扣合连接形成门槛梁型腔;第一加强组件,第一加强组件包括:第一加强板和第一支撑板,第一加强板与门槛外板连接,至少部分第一加强板设置在门槛梁型腔内,且至少部分第一加强板与至少部分门槛外板间隔设置;第一支撑板与第一加强板连接,且至少部分第一支撑板与至少部分第一加强板间隔设置以形成吸能腔。通过在门槛梁内设置第一加强组件,可以改善整车侧碰性能不足和门槛强度不足的缺点,以及受力变形量大的问题,从而可以提升车辆的如刚度、强度、维修、碰撞、NVH性能。
