The invention belongs to the technical field of humanoid robots, and particularly relates to a multistage linear lifting mechanism and a humanoid robot. The first-stage column body is fixedly connected with the bottom mounting piece; the second-stage column body is arranged on the first-stage column body in a sliding manner; the third-stage column body is arranged in the second-stage column body in a sliding manner; the driving device comprises an electric cylinder fixed on the bottom mounting piece and a servo motor connected with the electric cylinder, and the output end of the electric cylinder is connected with the second-stage column body through an electric cylinder connecting piece and a second-stage column connecting piece; the driving device drives the second-stage column body to move relative to the first-stage column body, and drives the third-stage column body to move at the speed twice the moving speed of the second-stage column body through the transmission mechanism. The novel structural layout is adopted, the dynamic upsetting moment resistance of the mechanism is greatly improved, the occupied space of the mechanism is reduced, and the operation speed of the mechanism during action execution is increased.

    本发明属于人形机器人技术领域,具体涉及一种多级线性升降机构及人形机器人,包括:底部安装件;一级柱体,与底部安装件固定连接;二级柱体,滑动设置在一级柱体;三级柱体,滑动设置在二级柱体内;驱动装置,包括固定在底部安装件上的电缸以及与电缸连接的伺服电机,电缸的输出端通过电缸连接件和二级柱连接件与二级柱体连接;驱动装置驱动二级柱体相对于一级柱体运动,并通过传动机构带动三级柱体以二级柱体运动速度的二倍速运动。本发明采用新的结构布局,极大提高了机构的抗动态倾覆力矩能力,以及减小了机构的占用空间,提升了执行动作时的机构运行速度。
