Embodiment 1

[0069] Embodiment 1: in conjunction with all accompanying drawings; a kind of folding helicopter rotor system, it is characterized in that,

[0070] The propeller part includes an upper rotating shaft 214 and a lower rotating shaft 225 nested with each other, an upper rotating group 224 is installed on the upper rotating shaft 214, and a lower rotating group 221 is installed on the lower rotating shaft 225;

[0071] The upper rotating group 224 includes a rotating inner shaft clamp 207 fixed on the upper rotating shaft 214, and more than one folding paddle clamp 208 is arranged on the rotating inner shaft clamp 207. The folding paddle clamp rotating shaft 226 and the rotating inner shaft clamp 207 Integratively connected and the folded paddle hoop rotating shaft protrudes outward based on the rotating inner shaft clamp 207, the folded paddle hoop 208 is sleeved on the folding paddle hoop rotating shaft 226 and can rotate around the folding paddle hoop rotating shaft 226; the mi...

Embodiment 2

[0079] Embodiment 2: As a further improved solution or a side-by-side solution or an optional independent solution, the rotation directions of the upper rotation group 224 and the lower rotation group 221 are inconsistent.

[0080] The substantive technical effect and the realization process of the technical solution here are as follows: the inconsistent direction of rotation is realized by the transmission of the gear train, further realizing the lifting of the drone.

Embodiment 3

[0081] Embodiment 3: As a further improved solution or a side-by-side solution or an optional independent solution, both the upper rotating group 224 and the lower rotating group 221 each include two paddles and the two paddles are arranged symmetrically to each other. The substantive technical effect and the realization process of the technical solution here are as follows: the symmetrical arrangement can conveniently realize the balanced rotation.

Abstract

The invention relates to the field of unmanned aerial vehicles, in particular to a folding helicopter rotor system and a support-free light unmanned aerial vehicle. An upper rotating group (224) comprises a rotating inner shaft hoop (207) fixed on an upper rotating shaft (214), more than one folding paddle hoop (208) is arranged on the rotating inner shaft hoop (207), a folding paddle hoop rotating shaft (226) and the rotating inner shaft hoop (207) are integrally connected, the folding paddle hoop rotating shaft extends outwards based on the rotating inner shaft hoop (207), the folding paddle hoop (208) is sleeved on the folding paddle hoop rotating shaft (226) and can rotate around the folding paddle hoop rotating shaft (226); and the middle part of the folding paddle hoop (208) is rotatably provided with a paddle (210) through a rotating shaft and a torsion spring (209). The system and the unmanned aerial vehicle have the advantages of being diversified in function, foldable, better in using effect, safer, capable of being recycled, capable of achieving self protection and capable of adopting auxiliary power to ascend and descend.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a folding helicopter rotor system and a support-free light unmanned aerial vehicle. Background technique [0002] Since the UAV entered the plant protection market, its high-altitude operation method is conducive to the growth of plants and does not damage plants. It has gradually replaced the traditional operation method and is favored by the majority of users. However, due to the problems of load, battery life and down-pressure wind field, the work efficiency and control effect are mediocre. [0003] UAVs have been widely used in police force, urban management, agriculture, geology, meteorology, electric power and other fields. The flight control computer system of UAVs is the core of the "brain" of UAVs and the central control unit of the flight control system. Computing speed plays a vital role in the control of drones. [0004] At present, most drones are consumer-g...
