The doorsill beam structure comprises a doorsill inner plate and a doorsill outer plate, the doorsill inner plate and the doorsill outer plate are fixed, and a rigid cavity is formed between the doorsill inner plate and the doorsill outer plate; the doorsill reinforcing inner plate is fixed to the inner side of the doorsill inner plate, and the side, close to the doorsill outer plate, of the doorsill reinforcing inner plate is sunken to form a first energy absorption cavity; the doorsill reinforcing outer plate is arranged on the side, away from the doorsill inner plate, of the doorsill reinforcing inner plate in a sleeving mode, and the side, close to the doorsill outer plate, of the doorsill reinforcing outer plate is sunken to form a second energy absorption cavity; the first energy absorption cavity and the second energy absorption cavity are distributed in a stacked mode from inside to outside, and the width of the second energy absorption cavity in the vertical direction is smaller than that of the first energy absorption cavity in the vertical direction. Progressive deformation energy absorption can be achieved through the doorsill beam structure, the structural strength of weak outside and strong inside is achieved, absorption of external impact force is facilitated, and damage to a passenger compartment and extrusion to a battery pack are reduced.

    本申请涉及一种门槛梁结构及车辆,其包括:门槛内板和门槛外板,所述门槛内板和所述门槛外板固定,并与所述门槛外板之间形成刚性腔室;门槛加强内板,所述门槛加强内板固定于所述门槛内板的内侧,并朝向靠近所述门槛外板的一侧凹陷形成第一吸能腔室;门槛加强外板,所述门槛加强外板套设于所述门槛加强内板远离所述门槛内板的一侧,并朝向靠近所述门槛外板的一侧凹陷形成第二吸能腔室;所述第一吸能腔室与所述第二吸能腔室自内而外叠加分布,且所述第二吸能腔室沿竖直方向的宽度小于所述第一吸能腔室沿竖直方向的宽度。通过该门槛梁结构可以起到递进变形吸能,达到外弱内强的结构强度,利于外部撞击力吸收,减少对乘员舱伤害和电池包的挤压。
