Embodiment Construction

[0054]In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top", "bottom" etc. used in this specification is based on the orientation or positional relationship shown in the drawings, and is only In order to facilitate the description of the invention and simplify the description, it does not indicate or imply that the device or element referred to must have a speci...

Abstract

Embodiments of the invention specifically disclose a folding propeller, a power assembly and an unmanned aerial vehicle, belonging to the technical field of propellers. The folding propeller comprisesa propeller hub, at least two paddles and at least two connecting members, wherein the propeller hub is used for mounting the folding propeller onto a drive unit and comprises a first surface and a second surface which are arranged face to face; the first surface faces the drive unit, and the second surface has its back facing the drive unit; each of the paddles is mounted on the second surface by one corresponding connecting member; and the blades can both rotate relative to the propeller hub. Thus, the rotational damping between the paddles and the propeller hub can be adjusted by only adjusting the frictional force of one contact surface during injection molding, so mold adjustment is convenient, batch production can be realized and production cost can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of propellers, in particular to a folding propeller, a power assembly using the folding propeller, and an unmanned aerial vehicle using the power assembly. Background technique [0002] UAV is an unmanned aircraft that controls the flight attitude through radio remote control equipment and built-in programs. Because of its advantages such as flexible maneuvering, quick response, unmanned, and low operating requirements, it has been widely used in aerial photography, Plant protection, power inspection, disaster relief and many other fields. With the development of wireless Internet, wireless local area network and image processing technology, drones have been favored by more and more users. [0003] The propeller is an important part of the power assembly of the UAV. It usually consists of a propeller hub and two or more axisymmetrically distributed propeller blades. The propeller blade...
