Title:
FOLDING PROPELLER, POWER ASSEMBLY, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/033769
Kind Code:
A1
Abstract:
Disclosed in the present application are a folding propeller, a power assembly, and an unmanned aerial vehicle. The folding propeller comprises: a propeller hub, at least two blade assemblies, and a connector for pivoting the propeller hub and the blade assembly. Each of the blade assemblies is rotatable relative to the propeller hub and a rotation axis of each of the blade assemblies is perpendicular to an axial centerline of the propeller hub. In the folding propeller provided by the embodiment of the present application, the blade assembly can be folded up or down with respect to the propeller hub to improve space utilization and facilitate carrying. Moreover, when applied to a tilting rotor unmanned aerial vehicle, the blade assembly can also be folded during flight to reduce flight resistance.
