The invention relates to an automobile body part, in particular to an automobile body side doorsill reinforcing structure. According to the technical scheme, the car body side doorsill reinforcing structure comprises a side doorsill with a groove-shaped section and an outward top and a reinforcer body matched with the inner side of a groove of the side doorsill, and the reinforcer body is formed by bending a steel plate and is provided with an upper cavity protruding outwards and a lower cavity protruding outwards. The lower edge of the upper cavity and the upper edge of the lower cavity are connected to form a connecting frame protruding inwards, and the section of the connecting frame is in a glasses shape. According to the reinforcing structure, it is guaranteed that the strength of the automobile body side wall threshold is high enough when the automobile is subjected to side collision, meanwhile, the formed cavity can reduce the invasion amount of the automobile threshold and can transmit and disperse energy, the material thickness can be properly reduced due to the cavity, and cost is saved on the premise that the collision performance is not affected.

    本发明涉及汽车车身部件,具体涉及一种车身侧围门槛加强结构。本发明的技术方案是一种车身侧围门槛加强结构,包括断面呈凹槽形且顶部向外的侧围门槛,与侧围门槛凹槽内侧配合的加强件本体,所述加强件本体由一块钢板弯折成型,具有一个向外凸起的上空腔、一个向外凸起的下空腔,上空腔的下边和下空腔的上边相连构成一个向内凸起的连接架,断面呈眼镜形。该加强结构不仅保证车辆在发生侧碰时车身侧围门槛强度足够高,同时形成腔体能够降低汽车门槛侵入量,并能够传递分散能量,因为腔体的产生可适当减小料厚,在不影响碰撞性能的前提下节约成本。
