The invention discloses a low-sitting-posture seat adjusting mechanism and a seat framework, and the low-sitting-posture seat adjusting mechanism comprises a height adjusting assembly which comprises a U-shaped guide bracket, a driving motor, a lead screw and a boss; the outer surface of the seat basin assembly is fixedly connected with a rear pipe, the inner surface of one side of the seat basin assembly is in shaft connection with a first connecting plate, one end of the first connecting plate is connected with a second connecting seat through a shaft, the lower surface of the second connecting seat is in sliding connection with a lower left side sliding rail, and the inner surface of the other side of the seat basin assembly is in shaft connection with a second connecting plate. One end of the second connecting plate is connected with a first connecting base through a shaft, a driving system is optimized, particularly, a traditional combination of a gear and a toothed plate is replaced with a combination of a motor and a lead screw nut mechanism, the space at the rear end can be released, and the height of the seat in the vertical direction can be further compressed. Meanwhile, the backrest rotating shaft can move downwards, so that the problem that the waist is jacked by a large-angle flat framework is solved, and the comfort of a vehicle seat is synchronously improved.

    本发明公开了一种低坐姿座椅调节机构以及座椅骨架,其包括:高调组件,高调组件包括U型导向支架、驱动电机、丝杆、凸台;坐盆总成,坐盆总成的外表面固定连接有后管,坐盆总成的一侧内表面轴连接有第一连板,第一连板的一端通过轴连接有连接座二,连接座二的下表面滑动连接有下左侧滑轨,坐盆总成的另一侧内表面轴连接有第二连板,第二连板的一端通过轴连接有连接座一,通过优化驱动系统,尤其是用电机和丝杆螺母机构的组合来取代传统的齿轮和齿板的组合,可以释放后端空间,可以进一步压缩座椅在竖直方向的高度。同时,靠背转轴可以实现下移,解决了大角度翻平骨架顶腰的问题,同步改善车辆座椅舒适性。
