The invention discloses a coaxial folding double-propeller mechanism and an aircraft. The coaxial folding double-propeller mechanism comprises a sleeve assembly, an inner shaft assembly, a linkage assembly and a driving structure. The sleeve assembly comprises a sleeve and a first paddle hinged to the sleeve. The inner shaft assembly comprises an inner shaft and a second paddle hinged to the inner shaft. The linkage assembly comprises a linkage seat, a rotating seat, a first connecting structure and a second connecting structure. The linkage base is slidably arranged on the outer side of the sleeve in a sleeving mode. And the linkage seat and the rotating seat are rotationally connected and axially positioned, so that the linkage seat and the rotating seat synchronously slide. The two ends of the first connecting structure are connected with the first paddle and the linkage base correspondingly so that the linkage base can drive the first paddle to be unfolded when sliding. The two ends of the second connecting structure are connected with the rotating base and the second paddle correspondingly so that the second paddle can be driven to be unfolded when the rotating base slides. And the driving structure drives the linkage seat to slide along the axis of the sleeve. Compared with the prior art, the problem that the paddles cannot be unfolded when the rotating speed is low can be solved.

    本发明公开了一种共轴折叠双桨机构及飞行器,共轴折叠双桨机构包括套管组件、内轴组件、联动组件和驱动结构。套管组件包括套管和铰接于套管上的第一桨叶。内轴组件包括内轴和铰接于内轴上的第二桨叶。联动组件包括联动座、旋转座、第一连接结构和第二连接结构。联动座滑动套设于套管外侧。联动座与旋转座转动相连且轴向定位,以使联动座与旋转座同步滑动。第一连接结构的两端分别连接第一桨叶和联动座,以使联动座滑动时能够驱动第一桨叶展开。第二连接结构的两端分别连接旋转座和第二桨叶,以使旋转座滑动时能够驱动第二桨叶展开。驱动结构驱动联动座沿套管的轴线滑动。与现有技术相比,本发明能够解决桨叶转速较低时无法展开的问题。
