Title:
PROPELLER, POWER APPARATUS, POWER SYSTEM, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/236820
Kind Code:
A1
Abstract:
Provided are a propeller, a power apparatus, a power system, and a multi-rotor unmanned aerial vehicle. The power apparatus comprises a driving motor (70) used for being connected to a propeller (2) to drive the propeller (2) to rotate; the driving motor (70) comprises a rotating portion and an upper cover (20); the upper cover (20) is of a single-layer structure and directly connected to a rotor of the driving motor (70); moreover, the rotor and the upper cover (20) of the driving motor are respectively made of different materials; the upper cover (20) is used for being fixedly connected to the propeller (2), so that the rotor of the driving motor (70) is fixedly connected to the propeller (2); and when the rotor of the driving motor (70) rotates, the propeller (2) is driven to rotate. The upper cover (20) is of the single-layer structure and directly connected to the rotor of the driving motor (70), and it is not needed to additionally provide a propeller seat to load the upper cover (20) on the driving motor (70), thereby reducing the number of parts, realizing the effect of reducing the weight of the power apparatus, and being beneficial for reducing the size of the unmanned aerial vehicle. Moreover, the upper cover (20) can be made of a material that is different from the material of the rotor and light in weight, and thus, the weight of the power apparatus can be further reduced.
