The embodiment of the invention discloses a gear-type synchronous folding propeller structure, which comprises a propeller hub, a gear-type synchronous folding propeller, a gear-type synchronous folding propeller and a gear-type synchronous folding propeller, the plurality of gear seats are synchronously and rotationally assembled in the mounting groove, the plurality of gear seats are rotationally and symmetrically distributed based on the central axis of the propeller hub, and the intersecting line between the planes where the plurality of gear seats rotate coincides with the central axis of the propeller hub; and the plurality of paddles are fixedly connected to the plurality of gear seats in a one-to-one correspondence manner, and the plurality of paddles extend to the outer part of the mounting groove from the corresponding gear seats. The technical problems that in the prior art, when an unpowered mode of a propeller is switched, folding synchronism of the blades is poor, and synchronous folding of all the blades cannot be completed through one set of driving input are solved.

    本发明实施例公开了一种齿轮式同步折叠螺旋桨结构,包括:桨毂,沿其中心轴延伸方向的一端部开设有安装槽;若干个齿轮座,同步转动装配于所述安装槽的内部,所述若干个齿轮座之间基于所述桨毂的中心轴呈旋转对称分布,且所述若干个齿轮座的转动所处平面之间的交线与所述桨毂的中心轴相重合;若干个桨叶,分别一一对应固接于所述若干个齿轮座,且所述若干个桨叶分别自对应的所述齿轮座延伸至所述安装槽的外部。解决了现有技术对于螺旋桨的无动力模式切换时,桨叶的折叠同步性较差,无法通过一组驱动输入即可完成全部桨叶的同步收拢的技术问题。
