The invention relates to a doorsill beam assembly and an automobile. The assembly comprises a doorsill beam body and a reinforcing structure, the doorsill beam body is a hollow structure formed by extruding metal materials, a plurality of body separation surfaces are arranged in the doorsill beam body, and the body separation surfaces are used for separating the doorsill beam body into a first cavity and a plurality of second cavities in the radial direction of the doorsill beam body; and the reinforcing structure is a hollow structure formed by extruding metal materials, the first cavity is filled with the reinforcing structure, and the radial section shape of the reinforcing structure is matched with the radial section shape of the first cavity. The capability of resisting crushing deformation of the doorsill beam can be improved, and the small offset collision performance of the automobile is improved.

    本发明涉及一种门槛梁组件及汽车。包括门槛梁本体和加强结构,门槛梁本体为采用金属材料挤压成型的中空结构,门槛梁本体内设置有多个本体分隔面,本体分隔面用以沿门槛梁本体的径向将门槛梁本体分隔成第一腔体和多个第二腔体;加强结构为采用金属材料挤压成型的中空结构,加强结构填充在第一腔体内,加强结构的径向截面形状与第一腔体的径向截面形状匹配。本发明可以提高门槛梁的抵抗压溃变形的能力,提升汽车小偏置碰撞性能。
