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. 1, 4 and 6, the driving device 4 may include a driving mechanism 41 and a pulling wire 42, the driving mechanism 41 is mounted to the body assembly 1, the pulling wire 42 is connected to the driving mechanism 41, and the pulling wire 42 is also connected to the power device 3, for example, the pulling wire 42 may pass through the inside of the arm device 2 or be pulled along the arm device 2 outside the arm device 2, so that the driving mechanism 41 drives the power unit 31 to rotate around the predetermined axis L relative to the arm device 2 through the pulling wire 42.

From this, install actuating mechanism 41 on fuselage assembly 1 can be through acting as go-between 42, the power pack 31 that the pulling is located the outer end of horn device 2 rotates around predetermineeing axis L, in order to change unmanned aerial vehicle 100's flight gesture, for example, change flight direction etc., therefore, install in fuselage assembly 1 through actuating mechanism 41 with among the drive arrangement 4, thereby can make full use of fuselage assembly 1's space, be favorable to improving unmanned aerial vehicle 100's overall structure compactness, and can make unmanned aerial vehicle 100's complete machine focus comparatively concentrate, structural stability is high, compare in the scheme of installing drive arrangement 4 in horn device 2, can reduce the bearing of horn device 2, improve the life of horn device 2.

Thus, the mounting post 321 can more simply and effectively limit the rotation post 322, and the rotational stability of the rotation post 322 can be improved.

In some embodiments of the present invention, as shown in fig. 4, the outer peripheral wall of the rotation post 322 has driving arms 323 respectively located at two sides of the rotation post 322 (where the two sides refer to two sides of a plane passing through the axis of the rotation post 322), the pulling wires 42 are respectively connected to the driving arms 323 at two sides, and the driving mechanism 41 pulls the driving arms 323 at two sides to move oppositely through the pulling wires 42, for example, in the example shown in fig. 4, one pulling wire 42 moves upward and the other pulling wire 42 moves downward to pull the rotation post 322 to rotate. Thus, the pulling wire 42 can simply and effectively pull the rotation post 322 to rotate.

However, the present invention is not limited thereto, and the mounting post 321 and the rotating post 322 may be made of wear-resistant material.

For example, in some embodiments of the present invention, as shown in fig. 5, the outer circumferential wall of the rotation column 322 may have two driving arms 323 spaced apart along the circumference of the rotation column 322 (for example, the two driving arms 323 may be respectively located at two sides of the diameter direction of the rotation column 322), and as shown in fig. 4 and 6, the driving device 4 may include two pulling wires 42, each pulling wire 42 having a first end 421 and a second end 422, the first ends 421 of the two pulling wires 42 being respectively connected to the driving mechanism 41, the second ends 422 of the two pulling wires 42 being respectively connected to the two driving arms 323, and the driving mechanism 41 being configured to drive the two pulling wires 42 to move relatively to pull the rotation column 322 to rotate. Therefore, the pull wire 42 can simply and effectively pull the rotating post 322 to rotate, and the connection between the rotating post 322 and the pull wire 42 is convenient. Of course, the present invention is not limited thereto, for example, in other embodiments of the present invention, the driving device 4 may further include only one pulling wire, both ends of the pulling wire are respectively connected to the two driving arms 323, and the rotation of the rotation column 322 may also be driven by winding the pulling wire forward and backward.

In some embodiments of the present invention, as shown in fig. 4, the power unit 3 may further include: pulley assembly 33, pulley assembly 33 includes a support frame 331 and a pulley 332, support frame 331 is connected to the outer end of the arm device 2, pulley 332 is rotatably installed on support frame 331, and the pull wire 42 is guided by pulley 332. Therefore, the pulley 332 can be fixed to the arm device 2 by the support frame 331, and the guide direction of the wire 42 is changed by the sliding guide function of the pulley 332, so that the working efficiency of the driving device 4 can be improved.

For example, in a specific example, as shown in fig. 5, the pulley assembly 33 may include a support frame 331 and two pulleys 332, the support frame 331 is connected to the outer end of the arm device 2, the two pulleys 332 are respectively rotatably mounted on the support frame 331, and the two pull wires 42 are respectively guided and slid by the two pulleys 332. Therefore, the pulley 332 can be fixed on the arm device 2 through the support frame 331, and the guiding direction of the two wires 42 is changed through the guiding and sliding action of the pulley 332, so that the working effectiveness of the driving device 4 can be improved.

For example, in some embodiments of the present invention, as shown in fig. 6 to fig. 8, when the steering engine 412 drives the adaptor 411 to rotate around the central axis of the central column 4111, the two rotating arms 4112 may be driven to rotate, so that the rotation of the rotating arms 4112 drives the two pull wires 42 to move relatively (i.e., the moving directions of the two pull wires 42 are opposite), so as to pull the rotating column 322 to rotate, thereby driving the propeller 312 to rotate, and changing the flight direction. For example, in some embodiments, after the steering engine 412 drives the adaptor 411 to rotate clockwise by a certain angle to change the flight direction and fly to a predetermined position, the steering engine 412 can drive the adaptor 411 to rotate counterclockwise by a certain angle to complete the flight actions of the drone 100, such as hovering or reverse flight.

From this, steering wheel 412 is not directly continuous with adaptor 411, thereby can utilize gear train 4132 to produce the effect of speed reduction or acceleration rate, and then can set up the steering wheel 412 of different power according to the circumstances of difference, for example, when gear train 4132 is reduction gear train, can utilize reduction gear train's characteristic, when drive arrangement 4 drive power device 3, realize the fine setting of fine setting screw 312 inclination, thereby can improve the flight direction's of unmanned aerial vehicle 100 controllability, simultaneously, can also utilize meshing pivoted characteristic between the gear of each grade in gear train 4132, realize when steering wheel 412 stop work, make the stay wire 42 can keep in this position, thereby further improve the stability of the controllability and the flight of unmanned aerial vehicle 100.
