The invention relates to the technical field of automobile part design, and discloses an automobile doorsill beam reinforcing structure and an automobile doorsill beam structure.The automobile doorsill beam reinforcing structure is used for being installed in a cavity of a doorsill beam outer plate, is made of fiber reinforced composites.The automobile doorsill beam reinforcing structure comprises a reinforcing body, a reinforcing rib and a reinforcing rib, the cross section of the reinforcing body is in a C shape in the direction intersecting with the axial direction of the reinforcing body, and first reinforcing spokes extend from the inner side face of the reinforcing body to the opening direction of the reinforcing body. The automobile doorsill beam reinforcing structure provided by the invention is prepared from the fiber reinforced composite material, and meanwhile, the cavity of the doorsill beam outer plate is fully utilized, and the doorsill beam reinforcing structure is designed to be C-shaped, so that the sectional inertia moment of the whole doorsill beam is increased, and the doorsill beam has higher flexural rigidity, and therefore, under the condition that the target rigidity is ensured, the rigidity of the doorsill beam is improved. The weight is greatly reduced, and effective light weight is realized.

    本发明涉及汽车零部件设计技术领域,公开了一种汽车门槛梁加强结构及汽车门槛梁结构,汽车门槛梁加强结构用于安装在门槛梁外板的空腔中,其采用纤维增强复合材料制备而成,车门槛梁加强结构包括:加强主体,沿与加强主体的轴向相交的方向进行截面,加强主体的截面呈C型状,在加强主体的内侧面向加强主体的开口方向延伸出第一加强辐条。本发明提供的汽车门槛梁加强结构,采用纤维增强复合材料制备而成,同时充分利用门槛梁外板的空腔,将门槛梁加强结构设计为C型状,增加了门槛梁整体的截面惯性矩,使其具有更高的抗弯刚度,从而在保证目标刚度的情况下,大幅度的降低了其重量,实现了有效的轻量化。
