In other embodiments, the locking pin 32 may be clamped in such a way that a locking groove is provided in the lock 50.
Specifically, referring to fig. 14, since the locking pin 32 needs to move in the direction of the lock catch 50, in order to facilitate the relative sliding of the locking pin 32 and the lock catch 50, the locking surface 52 gradually inclines downward in the direction away from the middle wing 10, and when the outer wing 20 is in the closed state, the included angle between the locking surface 52 and the horizontal plane is between 12 ° and 18 °, so that the locking surface 52 is inclined downward, and when locking with the locking pin 32, a guiding effect is generated for the movement of the locking pin 32, and meanwhile, the locking pin 32 can smoothly contact with the locking surface 52 of the lock catch 50, so that the intermittent motion can be counteracted. For example, the angle between the lock surface 52 and the horizontal surface may be set to 12 °,13 °, 15 °, 17 °, 18 °, or the like, and is not limited thereto.
In a specific embodiment of the present invention, the included angle between the locking surface 52 and the horizontal plane is 15 °, and by this included angle, the locking pin 32 can smoothly move onto the locking surface 52 of the lock catch 50, and locking of the locking pin 32 can be achieved under the pressure of the second elastic member 38.
The folding wing 100 is used as follows:
(1) When the unmanned aerial vehicle is in a flying state and gradually stops on the parking apron, the parking apron is provided with a magnetic mechanical arm 200, the outer wing 20 is in a closed state, the locking pin 32 is locked on the lock catch 50, and the whole folding wing 100 is positioned above the magnetic mechanical arm 200;
(2) When the outer wing 20 is folded, the magnetic mechanical arm 200 is electrified, the magnetic mechanical arm 200 generates a magnetic field, and the magnetic component 40 in the folding wing 100 is attracted to each other, so that a magnetic force is given to the magnetic component 40, the magnetic force pulls the magnetic component 40 to move downwards, the magnetic component 40 drives the sliding block 35 to slide relative to the fixed frame 25 and the first mounting plate 21 of the outer wing 20, the first elastic component 60 is compressed, and when the sliding block 35 moves to abut against the locking pin 32, the locking pin 32 is gradually driven to separate from the lock catch 50, and meanwhile, the movement of the lock catch 50 compresses the second elastic component 38;
(3) The magnetic mechanical arm 200 contracts downwards to drag the unmanned aerial vehicle to move, the outer wing 20 slides relative to the surface of the magnetic mechanical arm 200, and under the action of the magnetic force of the magnetic mechanical arm 200, the outer wing 20 rotates to 90 degrees relative to the middle wing 10, so that the folding of the middle wing 10 is realized;
(4) When the outer wing 20 and the middle wing 10 need to be closed, the magnetic force is cancelled, a pushing force is provided for the outer wing 20, at this time, the sliding block 35 slides along the fixing frame 25 towards the initial direction under the action of the elastic force of the first elastic piece 60, the locking pin 32 moves towards the lock catch 50 under the action of the second elastic piece 38, and finally, the locking pin is pressed on the locking surface 52 of the lock catch 50 under the pressure of the second elastic piece 38, so that the locking with the lock catch 50 is realized, and meanwhile, the outer wing 20 is closed relative to the middle wing 10.
