Abstract

The invention provides a connecting arm for a paddle of an unmanned aerial vehicle. The connecting arm comprises a propeller support frame and a connecting body for fixing the paddle, wherein the connecting body is fixedly arranged at one end of the propeller support frame, and is in rolling contact with the surface of the propeller support frame. By implementing the connecting arm, the paddle onthe propeller can be rotated at an arbitrary angle through the rolling-contact connecting mode between the propeller support frame and the connecting body, and rolling contact can realize control of an arbitrary precise rotating angle under control of an external control device and cannot be influenced by environmental factors.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle blade connecting arm. Background technique [0002] At present, the existing UAV propellers are fixed by means of traditional external propellers or nuts, or are integrated with the propeller blades through a built-in threaded propeller cap. The blades of this kind of propeller are not adjustable during flight, but the UAV is performing operations such as aerial photography, agriculture, plant protection, selfie, express delivery, disaster rescue, wildlife observation, video surveillance shooting, surveying and mapping, and news reporting. When flying, precise control of the flight direction is required, but the current one-piece propeller cannot achieve this. [0003] In order to realize the controllability of the blades on the propeller, the solution in the prior art is to process the spinner cap and the blade part separately. Finall...
