Title:
PROPELLER, POWER ASSEMBLY, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/062389
Kind Code:
A1
Abstract:
A propeller (10), a power assembly (100), and an unmanned aerial vehicle, relating to the technical field of propellers. The propeller (10) comprises: a hub (11) and at least two blades (12); the hub (11) comprises a housing (111), an upper cover (112), and at least two gears (113); the upper cover (112) is mounted at one end of the housing (111) and is able to rotate with respect to the housing (111); the upper cover (112) is provided with a teeth part (1121); the at least two gears (113) are received in the housing and are meshed with the teeth part (1121); the at least two blades (12) have one-to-one correspondence to the at least two gears (113); one end of each blade (12) is mounted inside the housing and is fixedly connected to the corresponding gear (113); each blade (12) is able to rotate with respect to the housing (111); during rotation, the upper cover (112) drives the at least two gears (113) to rotate, so as to enable the at least two blades (12) to rotate with respect to the housing (111), thereby changing the pitch of the blades (12). According to the method, the pitch of a propeller (10) can be adjusted, and thus an unmanned aerial vehicle using the propeller (10) can adapt to different flight requirements.
