The invention relates to the technical field of automobile design and manufacturing, in particular to an energy absorption threshold beam assembly and a vehicle. The energy-absorbing doorsill beam assembly comprises a doorsill outer plate, a doorsill inner plate and a doorsill reinforcing beam, and a cavity is formed between the doorsill outer plate and the doorsill inner plate. The doorsill stiffening beam is arranged in the cavity and comprises a plurality of crumple units sequentially arranged in the Y direction, the section of each crumple unit is in an 8 shape, each crumple unit comprises a first energy absorption cavity and a second energy absorption cavity, a buffering section is connected between each first energy absorption cavity and the corresponding second energy absorption cavity, each first energy absorption cavity comprises a first inclined plate, and each second energy absorption cavity comprises a third inclined plate. The first inclined plate and the third inclined plate are connected to the two ends of the buffering section respectively and located on the same side of the buffering section, and the ends, away from the buffering section, of the first inclined plate and the third inclined plate are arranged in the direction away from each other. The embodiment of the invention provides an energy-absorbing threshold beam assembly and a vehicle. The problem that in the related technology, the collision performance of a threshold beam is poor is solved.
