Title: PROPULSION SYSTEM FOR UNMANNED AERIAL VEHICLE, METHOD FOR COUPLING PROPELLER, AND UNMANNED AERIAL VEHICLE
Abstract:
Disclosed is a propulsion system for an unmanned aerial vehicle, the system comprising a propulsion motor (121) and a locking device (203). The propulsion motor (121) is used to drive a propeller (122) of the unmanned aerial vehicle (100). The locking device (203) is used to releasably couple the propeller (122) to the propulsion motor (121). The locking device (203) comprises a matching part (301), a part of the matching part (301) being able to move with respect to the propulsion motor (121) and/or the propeller (122) along a rotating axis (302) of the propulsion motor (121) such that the matching part (301) is located in a matching position where the propeller (122) and the propulsion motor (121) are locked and in a separated position different from the matching position. The propulsion system can improve the safety of the unmanned aerial vehicle. Further disclosed are a propeller for an unmanned aerial vehicle, an unmanned aerial vehicle, a suite of the unmanned aerial vehicle, a method for coupling the propeller to the unmanned aerial vehicle, a controller for the vehicle body, a control system, and a method for operating the controller in the unmanned aerial vehicle.
