Title:
MULTIROTOR UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/103037
Kind Code:
A1
Abstract:
Provided is a multirotor unmanned aerial vehicle (1), comprising: a body (11), multiple arms (12), and a number of rotor assemblies (13) equal to the number of arms (12). The multirotor unmanned aerial vehicle (1) is provided with a first rotor assembly (131) and a second rotor assembly (132) having motors rotating in opposite directions, so as to cause a first blade (1311) and a second blade (1321) to rotate in opposite directions. A first engagement mechanism (1311b) of the first rotor assembly (131) is different from a second engagement mechanism (1321b) of the second rotor assembly (132). A first coupling mechanism (1312b) of the first rotor assembly (131) is different from a second coupling mechanism (1322b) of the second rotor assembly (132). Thus, the first blade (1311) can only be assembled with a first motor (1312) and the second blade (1321) can only be assembled with a second motor (1322). The structural differences between the engagement mechanisms and the coupling mechanisms can be easily distinguished by a user, thereby avoiding the issue in which an aerial vehicle cannot fly normally because the blades that rotate in opposite directions have been installed backwards.
