Referring to fig. 1 to 16, the folding and unfolding process of the arm 20 of the unmanned aerial vehicle 1 provided in this embodiment is specifically described as follows:

when the arm 20 is unfolded from the folded state, the arm 20 is rotated to rotate the sleeve portion 221 of the pivot member 220 into the fitting cavity 1121 of the fitting portion 112, so that the third outer wall 2215 and the fourth outer wall 2216 are respectively and correspondingly abutted against the two end walls 1122, and the second outer wall 2214 is abutted against the inner arc wall 1123, and at this time, the peripheral wall of the first fitting groove 1124 and the peripheral wall of the second fitting groove 2211 form a circumferential surface together. The second locking member 320 is rotated to move the fourth end 322 closer to the second end 312, so that the circumferential surface formed by the first arc surface 313 and the second arc surface 323 is fitted to the circumferential surface formed by the circumferential wall of the first fitting groove 1124 and the circumferential wall of the second fitting groove 2211. The pulling member 331 is rotated to make the connecting rod 3322 pass through the gap 3123 and extend into the engaging groove 3121, and the two first pivot protrusions 3311 are correspondingly abutted against the two retaining protrusions 3122 one by one, so that the two first pivot protrusions 3311 are retained in the engaging groove 3121. At this time, the pulling member 331 is rotated reversely, so that the first pivot protrusion 3311 presses the inner wall of the engaging groove 3121, and the first pivot protrusion 3311 rotates eccentrically with respect to the second pivot rod 3323, and when the first pivot protrusion 3311 presses the engaging groove 3121, a contact surface between the first pivot protrusion 3311 and the engaging groove 3121 is changed from a surface closer to the axis of the second pivot rod 3323 to a surface farther from the axis of the second pivot rod 3323, thereby increasing the pre-tightening force. In addition, the first arc surface 313 and the second arc surface 323 press the peripheral wall of the first engagement groove 1124 and the peripheral wall of the second engagement groove 2211, respectively. When the trigger 331 rotates until the locking element 333 approaches the locking groove 324, the locking element 333 is pulled to match the locking element 333 with the locking groove 324, so as to fix the trigger 331 and realize the unfolding and fixing of the horn 20.

When the arm 20 is folded from the unfolded state, the unlocking portion 3332 is pressed to disengage the locking portion 3331 from the locking groove 324. The pulling member 331 is rotated to disengage the two first pivot protrusions 3311 from the engaging groove 3121, and the connecting rod 3322 is disengaged from the gap 3123. The second locking fitting 320 is rotated such that the second locking fitting 320 is disengaged from the first locking fitting 310. Then, the horn 20 is rotated to separate the sleeve-joint part 221 from the matching cavity 1121 until the sleeve-joint part is clamped with the fastener 121 on the mounting frame 120, so that the horn 20 is folded and fixed.

To sum up, the embodiment of the present invention provides an unmanned aerial vehicle 1, when the horn 20 is unfolded relative to the fuselage 10, moves through the fourth end 322 of the block assembly 330, until the block assembly 330 blocks with the second end 312, so as to fix the pivot joint member 220 and the fitting portion 112 between the first locking member 310 and the second locking member 320, so as to fix the foldable horn 20 more firmly when the horn 20 is unfolded. Moreover, the folding of the horn 20 is easy to operate, simple in structure and firm in fixation.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
