PROPELLER, POWER SET AND UNMANNED AERIAL VEHICLE

WIPO Patent Application WO/2022/227054

A1

A propeller, a power set, and an unmanned aerial vehicle, the propeller comprising a propeller clamp (10), at least two blades (11), and at least two rotating shafts (12); connecting ends (111) of the blades (11) are provided with through holes (112), the propeller clamp (10) is internally provided with accommodating spaces (S) used for accommodating the connecting ends (111), and the rotating shafts (12) penetrate through the through holes (112). In an unfolded state, the propeller clamp (10) abuts against the connecting ends (111) to limit the axial movement of the blades (11) along the rotating shafts (12); and in a folded state, the propeller clamp (10) is released from the connecting ends (111), and the blades (11) can move in the axial direction of the rotating shafts (12). The described structure can to a certain extent avoid the design in which the plane of the fuselage must be lower than the plane of the blades, thus reducing constraints to the structural design of the fuselage, and rendering a simple and compact structure.
