Abstract
An unmanned aerial vehicle (UAV) including a fuselage frame and a propulsion system coupled to the fuselage frame. The propulsion system includes a first propulsion device and a second propulsion device. The first propulsion device includes a first rotor blade assembly and a first rotor mount assembly, and the second propulsion device includes a second rotor blade assembly and a second rotor mount assembly. The first rotor mount assembly is configured to not allow the second rotor blade assembly to be assembled to the first rotor mount assembly.
Claims20
An unmanned aerial vehicle (UAV) comprising:
- a fuselage frame;
- and
- a propulsion system coupled to the fuselage frame and including:
- a first propulsion device including:
- a first rotor blade assembly including a first portion connecting two first blades;
- and
- a first rotor mount assembly including:
- a first rotor seat including:
- a first base;
- a first lock structure protruding from an upper surface of the first base, the first lock structure including a first recess opening towards the upper surface of the first base and configured to receive a first part of the first portion, the first part of the first portion being above the upper surface, and an uppermost surface of the first portion being not higher than a top surface of the first lock structure;
- and
- a second lock structure arranged at the first base, the second lock structure including a second recess opening towards the first base and configured to receive a second part of the first portion, and the uppermost surface of the first portion being not higher than a top surface of the second lock structure;
- and
- a first resilient member configured to provide an elastic force to the first portion to constrain the first portion in the first recess and the second recess;
- and
- a second propulsion device including:
- a second rotor blade assembly including a second portion;
- and
- a second rotor mount assembly including:
- a second rotor seat including:
- a second base;
- a third lock structure arranged at the second base, the third lock structure including a third recess opening towards the second base and configured to receive a first part of the second portion;
- and
- a fourth lock structure arranged at the second base, the fourth lock structure including a fourth recess opening towards the second base and configured to receive a second part of the second portion;
- and
- a second resilient member configured to provide an elastic force to the second portion to constrain the second portion in the third recess and the fourth recess;
- wherein the first rotor mount assembly is configured to not allow the second rotor blade assembly to be assembled to the first rotor mount assembly.
