Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Next, with reference to the drawings, a drone 100 according to an embodiment of the present invention is described.

As shown in fig. 1, the drone 100 according to an embodiment of the present invention may include: the aircraft comprises an aircraft body assembly 1, an arm device 2, a power device 3 and a driving device 4, wherein the two ends of the length of the arm device 2 are respectively the inner end and the outer end, the inner end of the arm device 2 is arranged on the aircraft body assembly 1, the power device 3 is arranged on the outer end of the arm device 2, the power device 3 comprises a power unit 31, and the power unit 31 comprises a power motor 311 and a propeller 312 arranged on the power motor 311. From this, when power device 3 during operation, power motor 311 can drive screw 312 and rotate to provide power for the flight of unmanned aerial vehicle 100.

As shown in fig. 2, the driving device 4 is mounted at the outer end of the horn device 2, and the driving power unit 31 rotates relative to the horn device 2 about a predetermined axis L, which is parallel to or coincides with a central axis L5 of the outer end of the horn device 2.
