When it is found that the fan blade 2 is too long to cause insufficient space of the containing container during the packaging and transportation of the unmanned aerial vehicle, the driving assembly 3 is started, the driving assembly 3 works to drive the folding assembly 4 to work, so that the fan blade 2 is folded and contracted into the shell 1 along the moving groove 101 until the fan blade 2 is completely arranged in the moving groove 101, thereby achieving the purpose of reducing the size of the unmanned aerial vehicle, so that the unmanned aerial vehicle can be placed in the container for packaging and transportation. By contracting the fan blade 2 of the unmanned aerial vehicle into the shell 1, the fan blade 2 can be further protected from being damaged during the transportation, and the shell 1 can play a certain protection role.

[0030] In this embodiment, preferably, the folding assembly 4 comprises a fixed plate 41 located on one side of the moving groove 101, the fixed plate 41 is fixedly connected with a fixed rod 42 on the inner wall of the shell 1, the fixed plate 41 is axially symmetrically connected with a rotating frame 43 at both ends, the rotating frame 43 is slidably connected with a moving plate 44 in the middle, one end of the moving plate 44 is fixedly connected with the fan blade 2, and the moving plate 44 is rotatably connected with a deflection plate 45 between the end away from the fan blade 2 and the rotating frame 43; when the size of the unmanned aerial vehicle is too large to be conveniently packaged and transported, in the initial state, the deflection plate 45 is coincided with the rotating frame 43 and located in the rotating frame 43, the moving plate 44 is moved to the inside of the shell 1, the moving plate 44 drives the fan blade 2 to move to the inside of the shell 1 along the moving groove 101 until the fan blade 2 completely enters the shell 1, the movement of the moving plate 44 drives the deflection plate 45 to rotate, the rotation of the deflection plate 45 drives the rotating frame 43 to rotate to both sides to form an "eight-shaped" state, at this time, the moving plate 44 is continuously moved, the movement of the moving plate 44 drives the deflection plate 45 to continue to rotate until the deflection plate 45 rotates to the outside of the rotating frame 43 but also is in the same straight line with the rotating frame 43, at this time, the two rotating frames 43 are also in the state of being pasted, at the same time, the moving plate 44 drives the fan blade 2 to completely enter the inside of the shell 1, which can protect the fan blade 2 to a certain extent, and the fixed plate 41 and the fixed rod 42 can provide support.

[0039] The working principle of the present application is: in the initial state, the moving plate 44 drives the fan blade 2 to be located outside the shell 1, at this time the limiting frame 5 is in contact with the two rotating frames 43, that is, the limiting frame 5 wraps the two rotating frames 43, at this time even if the moving plate 44 is moved towards the inside of the shell 1, the movement of the moving plate 44 cannot drive the deflection plate 45 and the rotating frame 43 to rotate, which can ensure the stability of the fan blade 2 and the moving plate 44, when it is found that the fan blade 2 is too long to extend out of the shell 1 during the packaging and transportation of the unmanned aerial vehicle, the driving assembly 3 is started, the rotating shaft 32 is rotated on the top plate of the shell 1, the rotation of the rotating shaft 32 drives the second bevel gear 31 to rotate, the rotation of the second bevel gear 31 drives the first bevel gear 8 to rotate, thereby making the rotating rod 7 rotate, since the rotating rod 7 and the sleeve 6 are threadedly connected, the rotation of the rotating rod 7 drives the sleeve 6 to move inward, thereby driving the moving plate 44 to move inward along the moving groove 101, the movement of the moving plate 44 drives the deflection plate 45 to rotate, the rotation of the deflection plate 45 drives the rotating frame 43 to rotate to both sides, showing an "eight-shaped state", at this time the moving plate 44 is continuously moved, the movement of the moving plate 44 drives the deflection plate 45 to continue to rotate until the deflection plate 45 rotates to the outside of the rotating frame 43 but is in the same straight line with the rotating frame 43, at this time the two rotating frames 43 are also in contact with each other, at the same time, the moving plate 44 drives the fan blade 2 to completely enter the inside of the shell 1, at the same time, the movement of the moving plate 44 drives the first rack 10 to move inward, at this time the lifting plate 9 is in a closed state, the first rack 10 will be engaged with the first gear 11 arranged in the first groove 103 during the movement of the moving plate 44, the rotation of the first gear 11 drives the round rod 12 to rotate, the rotation of the round rod 12 drives the rotating ring 13 to rotate, in the initial state, the end of the jacking rod 15 is in contact with the bottom of the inclined groove 131, when the rotating ring 13 rotates until the inclined surface of the inclined groove 131 is in abutment with the jacking rod 15, at this time the rotating ring 13 is continuously rotated, since the design of the inclined groove 131 drives the jacking rod 15 to move upward along the through hole 14, thereby jacking the lifting plate 9 into the lifting groove 102, after that, the rotation of the rotating ring 13 will not affect the jacking rod 15, that is, the jacking rod 15 continuously keeps the lifting plate 9 in the lifting groove 102, the lifting plate 9 is in a retracted state, during this process, the fan blade 2 will enter the inside of the shell 1 along with the movement of the moving plate 44, when the fan blade 2 enters the inside of the shell 1, the rotating ring 13 is still continuously rotated during this process until the other end of the inclined surface of the inclined groove 131 is in contact with the jacking rod 15, the inclined surface is in a downhill direction relative to the jacking rod 15, the jacking rod 15 will move downward along the through hole 14, thereby driving the lifting plate 9 to move downward along the lifting groove 102, thereby sealing the entrance of the moving groove 101, which can protect the fan blade 2 to a certain extent, in addition, the movement of the moving plate 44 will drive the second rack 16 to move, the movement of the second rack 16 drives the second gear 17 in the second groove 104 to rotate,The rotation of the second gear 17 drives the vertical rod 18 to rotate. Since the vertical rod 18 and the rotating sleeve 19 are threadedly connected, the rotation of the vertical rod 18 drives the rotating sleeve 19 to move, thereby driving the lifting rod 20 to move downward and drive the downward pressing pad 21 to slightly press and fix the fan blade 2. The sliding connection between the lifting rod 20 and the shell 1 can avoid the rotation of the rotating sleeve 19 with the rotation of the vertical rod 18, thereby preventing the damage to the fan blade 2 during the packaging and transportation. This step occurs after the lifting plate 9 is opened and closed again, that is, after the fan blade 2 enters the inside of the shell 1 after the lifting plate 9 is opened, the downward pressing pad 21 is driven to move downward by the second rack 16. When the fan blade 2 reaches the final position, the downward pressing pad 21 just contacts the surface of the fan blade 2. At this time, the lifting plate 9 is also in the closed state. When the unmanned aerial vehicle is used, the moving plate 44 moves along the moving groove 101 to the outside of the shell 1. The second rack 16 is first engaged with the second gear 17, so that the downward pressing pad 21 is released from the contact with the fan blade 2. Then, the first rack 10 is engaged with the first gear 11 to drive the lifting plate 9 to open, thereby facilitating the movement of the fan blade 2 to the outside of the shell 1. When the fan blade 2 moves to the outside of the shell 1, the lifting plate 9 is finally in the closed state under the cooperation of the rotating ring 13, the inclined groove 131 and the top rod 15, thereby protecting the inside of the shell 1. The size of the upper side of the moving groove 101 is larger than the size of the fan blade 2, thereby facilitating the rotation of the vertical rod 18 to drive the downward pressing pad 21 to press and fix the fan blade 2 in this step.
