The invention discloses a zero-gravity seat framework mechanism and a vehicle, and relates to the technical field of automobile seats, and the zero-gravity seat framework mechanism comprises a support fixed in the vehicle; the seat framework is arranged at the upper part of the bracket; the seat framework comprises a cushion framework and a backrest framework, the lower end of the backrest framework is hinged to the first end of the cushion framework, and the first end of the cushion framework is rotationally connected to the first end of the support; the lead screw driving device is fixedly connected to the support, a lead screw of the lead screw driving device does linear motion, and the lead screw is connected to the second end of the cushion framework in a driving mode and drives the second end of the cushion framework to ascend and descend. The lead screw of the lead screw driving device drives the front end of the cushion framework to ascend or descend through linear motion, compared with other driving devices such as a driving gear, the linear driving mode is smooth in transmission and small in influence of loads, shaking caused by sharp changes of the loads in the seat angle adjusting process can be reduced, and the adjusting effect of the seat angle is improved. And the riding comfort is improved.

    一种零重力座椅骨架机构以及车辆,涉及汽车座椅技术领域,零重力座椅骨架机构包括支架,固定于车辆内部;座椅骨架,设置于支架的上部;座椅骨架包括坐垫骨架和靠背骨架,靠背骨架的下端铰接于坐垫骨架的第一端,坐垫骨架第一端转动连接于支架的第一端;丝杆驱动装置,固定连接于支架,丝杆驱动装置的丝杆做直线运动,丝杆驱动连接于坐垫骨架的第二端,驱动坐垫骨架的第二端上升和下降。本发明丝杠驱动装置的丝杆通过做直线运动驱动坐垫骨架的前端上升或者下降,直线驱动方式相较于其他驱动装置如驱动齿轮,传动比较平顺,受负载的影响小,可以减小座椅角度调节过程中,由于负载出现急剧变化出现的抖动,提高乘坐舒适性。
