Title:
PROPELLER STRUCTURE, POWER APPARATUS, AND UNMANNED AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2020/062509
Kind Code:
A1
Abstract:
A propeller structure, and a power apparatus and an unmanned aircraft using said propeller structure, the propeller structure comprising a propeller hub (10) and propeller blades (20) connected to the propeller hub (10). A connecting section (11) used for connecting an external drive component is provided on the propeller hub (10), and a propeller release auxiliary section (30) is provided near to the connecting section (11). The propeller release auxiliary section (30) is used to match with a propeller release tool for rapid separation of the connecting section (11) and the external drive component. In the solutions provided in the embodiments of the present invention, the provision of the propeller release auxiliary section (30) on the propeller hub (10) at a position near to the connecting section (11) that connects to the external drive component allows for matching with a propeller release tool for rapid separation of the connecting section (11) and the external drive component even when the end surface (101) of the propeller hub (10) is in contact with the drive component (40). When the power apparatus and the aircraft utilize the present propeller, damage to the drive component because of collision of the propeller during flight can be avoided, and the propeller and the drive component can be separated without damaging the propeller.
