Problems solved by technology

In the prior art, UAVs try their best to make a fuss about how to make them smaller, and do not comprehensively consider portability from multiple perspectives, so they cannot bring users a perfect sense of portability.
For example, in the non-working state, the blades and arms of the existing UAV are exposed outside, which is easy to cause damage during carrying or transportation, and the exposed blades will also bring danger to personnel

Abstract

The invention discloses a propeller folding device for an unmanned aerial vehicle. The propeller folding device comprises a base board, three or more vehicle arms, a center ring and a steering engine assembly; the vehicle arms are sequentially arranged on the base board in the circumferential direction, one ends of the vehicle arms are hinged to the base board through shafts and can rotate around the hinge points, and the other ends of the vehicle arms are used for intalling propeller assemblies of the unmanned aerial vehicle; the center ring is located in the middle of the base board, a connecting rod is arranged between each engine arm and the center ring, and the steering engine assembly is used for driving the center ring to rotate to push the vehicle arms to rotate to be unfolded or folded through the connecting rods. The propeller folding device has the advantages of being simpler in structure, easier and more convenient to operate, capable of greatly improving the portability and the like.

Description

technical field [0001] The invention mainly relates to the field of unmanned aerial vehicles, in particular to a propeller folding device suitable for multi-axis aircraft. Background technique [0002] At present, in the field of drones, multi-axis aircraft (multi-rotor drones) have attracted a large number of aircraft model enthusiasts and enthusiasts due to their simple structure, low cost, good control ability, hoverability, and suitable for personal use. With the diversity and richness of people's lifestyles, the general public has also developed a strong interest in this kind of aircraft, so the market demand for multi-rotor aircraft is huge, especially consumer-grade aerial photography drones. [0003] The main features of consumer-grade aerial photography drones are comprehensive functions, small and portable, simple operation, and good controllability. Among them, portability is one of the most notable features of consumer-grade aerial photography drones. Even if t...
