Title: PROPELLER, POWER SYSTEM, AND UNMANNED AERIAL VEHICLE
Abstract:
A propeller (20), a power system (100) comprising the propeller (20), and an unmanned aerial vehicle comprising the power system (100). The propeller (20) is configured to be connected to a drive device (10) and can be driven by the drive device (10) to rotate; the propeller (20) comprises a blade base (21) and blades (22) connected to the blade base (21); the blade base (21) comprises a plurality of snap-in portions (230) which can be securely connected to the drive device (10) in a predetermined direction; the blade base (21) further comprises a first foolproof portion (251) provided corresponding to at least one snap-in portion (230); the first foolproof portion (251) abuts against the corresponding snap-in portion (230) and can prevent the blade base (21) from being connected to the drive device (10) along a direction other than the predetermined direction. The snap-in portion (230) and the first foolproof portion (251) of the propeller (20) abut against each other, such that the propeller (20) is only allowed to be connected to the drive device (10) in the predetermined direction; moreover, the structure of the snap-in portion (230) and the first foolproof portion (251) abutting against each other is easy to shape and process.
