The hinged type extension arm comprises a storage frame, a driving part, a square spline shaft, a lead screw and a plurality of folding and unfolding truss units, one side face of the storage frame is of an open structure, an assembly plate is arranged on the side face, opposite to the open structure, of the storage frame, and the driving part is installed in the storage frame; one end of the square spline shaft is vertically mounted in the center of the assembly plate, and the lead screw sleeves the square spline shaft in a matched and sliding manner; nuts are arranged in the centers of the multiple folding and unfolding truss units, and when the multiple folding and unfolding truss units are in a folded state, the nuts of all the folding and unfolding truss units are in threaded connection with the lead screws. Wherein the driving part is in transmission connection with the square spline shaft and can drive the square spline shaft to rotate, the square spline shaft drives the lead screw to rotate and penetrate out of the center positions of the multiple folding and unfolding truss units, and after the lead screw stretches out to a preset position, the lead screw continues to rotate so as to drive the multiple folding and unfolding truss units to be sequentially unfolded outwards from the interior of the storage frame.

    本发明涉及一种基于伸缩丝杠螺母拖拽的铰接式伸展臂,包括收纳框架、驱动部、方花键轴、丝杠和多个折展桁架单元,收纳框架的一侧面为敞口结构,收纳框架与敞口结构相对的一侧面设有装配板,驱动部安装在收纳框架内,方花键轴的一端垂直安装在装配板的中心位置,丝杠适配滑动套设在方花键轴上;多个折展桁架单元的中心位置均设有螺母,多个折展桁架单元在折叠状态下,每个折展桁架单元的螺母均与丝杠螺纹连接;其中,驱动部与方花键轴传动连接并能够驱动方花键轴转动,方花键轴带动丝杠转动并从多个折展桁架单元的中心位置穿出,当丝杠伸出到预设位置后,丝杠继续转动进而驱动多个折展桁架单元依次从收纳框架内向外展开。
