The invention discloses a seat underframe assembly, and relates to the technical field of vehicle engineering. The seat bottom frame assembly comprises a bottom frame disc, and a first bottom frame leg and a second bottom frame leg which are sequentially arranged along the transverse direction; the underframe disc comprises a frame and a rotating shaft bearing structure fixed to the middle of the frame, the first underframe leg is fixed to the middle of the bottom face of the underframe disc, and the second underframe leg is fixed to the end of the bottom face of the underframe disc. The first underframe leg is of an integrated structure and comprises two stand columns sequentially arranged in the longitudinal direction and a supporting frame connected between the two stand columns. The tops of the stand columns are fixed to the underframe disc. Through the arrangement of the first underframe legs and the second underframe legs, the load transmitted to the underframe disc can be shared, stress concentration can be reduced, and the supporting capacity and the supporting stability are guaranteed. The first underframe leg is close to the rotating shaft bearing structure, and the first underframe leg is arranged to be of an integrated structure, so that the bearing capacity can be guaranteed, and more and severe loads can be borne.

    本发明公开了一种座椅底架组成,涉及车辆工程技术领域。座椅底架组成包括底架盘、以及沿着横向依次设置的第一底架腿和第二底架腿;底架盘包括边框和固定于边框中部的转轴承载结构,第一底架腿固定于底架盘的底面中部,第二底架腿固定于底架盘的底面端部;第一底架腿为一体式结构,包括在纵向依次排布的两个立柱、以及连接于两个立柱之间的支撑架;立柱的顶部固定于底架盘。通过第一底架腿和第二底架腿的设置,可以分担传递到底架盘的载荷,有利于减少应力集中,保证支撑能力和支撑的稳定性。其中,第一底架腿靠近转轴承载结构,通过其设置为一体式结构,可保证承载能力,以能够承担较多且恶劣的载荷。
