The embodiment of the invention relates to the technical field of propellers, and particularly discloses a folding propeller, a power assembly and an unmanned aerial vehicle. The folding propeller comprises a propeller hub, at least two propeller blades and at least two connecting pieces. The propeller hub is used for installing the folding propeller to a driving device. The propeller hub comprises a first surface and a second surface which are oppositely arranged, the first surface faces the driving device, and the second surface deviates from the driving device; each paddle is installed on the second surface through the corresponding connecting piece, and each paddle can rotate relative to the paddle hub. By means of the mode, rotation damping between the paddle and the paddle hub can be adjusted only by adjusting the friction force of one contact face during injection molding and mold adjustment, mold adjustment is convenient, batch production is facilitated, and the production cost is reduced.
本发明实施例涉及螺旋桨技术领域,具体公开了一种折叠螺旋桨、动力组件及无人机。所述折叠螺旋桨包括桨榖、至少两个桨叶以及至少两个连接件,所述桨榖用于将所述折叠螺旋桨安装至驱动装置;所述桨榖包括相对设置的第一表面和第二表面,所述第一表面朝向所述驱动装置,所述第二表面背离所述驱动装置;每个所述桨叶通过与其对应的一个所述连接件安装在所述第二表面,每个所述桨叶均能够相对所述桨榖旋转。通过上述方式,本发明实施例能够在注塑调模时仅需调整一个接触面的摩擦力即可调整桨叶与桨榖之间的转动阻尼,方便调模,有利于批量化生产,降低生产成本。
