The invention discloses a vehicle doorsill beam structure and a vehicle. The vehicle doorsill beam structure comprises an outer doorsill beam, an inner doorsill beam and a doorsill load-sharing beam, a first energy absorption cavity is formed in the inner doorsill beam, the inner doorsill beam is fixedly connected to the inner side of the outer doorsill beam, and a second energy absorption cavity is defined between the outer doorsill beam and the inner doorsill beam; one part of the doorsill load-sharing beam extends into the first energy absorption cavity, and the other part of the doorsill load-sharing beam is arranged in the second energy absorption cavity. The energy absorption effect of the vehicle doorsill beam structure is better, so that the collision safety performance of the vehicle doorsill beam structure is better, most collision force can be absorbed when a vehicle is subjected to lateral collision, the situation that the intrusion amount of a passenger compartment is too large in the collision process is avoided, the integrity of the passenger compartment can be guaranteed, and therefore the safety of passengers is guaranteed.

    本发明公开了一种车辆门槛梁结构和车辆,其中车辆门槛梁结构包括:外门槛梁、内门槛梁和门槛分载梁,所述内门槛梁内具有第一吸能空腔,所述内门槛梁固定连接在所述外门槛梁的内侧,以在所述外门槛梁与所述内门槛梁之间限定出第二吸能空腔;所述门槛分载梁的一部分伸入到所述第一吸能空腔内,所述门槛分载梁的另一部分设置在所述第二吸能空腔内。该车辆门槛梁结构的吸能效果更好,以使其的碰撞安全性能更好,以能够在车辆受到侧向碰撞时吸收大部分的碰撞力,避免在碰撞过程中乘员舱侵入量过大,以能够保证乘员舱的完整性,从而保证乘员的安全。
