[0054] Working principle: The wiring of the present invention is through FPC wiring, and the main control module 51, the auxiliary control module 52, the first driving part 1101, the second driving part 1111 and the motor are connected through the FPC wiring.
[0055] The first support frame 401, the second support frame 402 and the third support frame 403 play the role of connecting and guiding the cable. In the specific installation process, the FPC cable and the surfaces of the first support frame 401 and the third support frame 403 are fixed by double-sided adhesive tape, and the FPC cable passes through the gap between the second support frame 402 and the first rotating arm 1102 bracket, so that the FPC cable does not contact the rotating part of the UAV rotor bracket structure 11, which can prevent the FPC cable from being torn and twisted, thereby increasing the service life;
[0056] Among them, the wire inlet groove 6 and the second angle component 8 are used for the FPC wire row to enter the first shell 11011 and the second shell 11110 and connect with the corresponding first drive component 11012, the first angle group and the second drive component 11111, and the second angle component 11112, and the wire outlet groove 3 is used for the FPC wire row to enter the interior of the drone fuselage body 1 and connect with the main control module 51.
[0057] The main control module 51 controls the start of the driving motor 10121, and at the same time, the electromagnet 1332 is energized, and the driving motor 10121 drives the driving gear 10122 to rotate, and the driving gear 10122 drives the driven gear 10123 to rotate, and the driven gear 10123 rotates, and the rotating shaft 1103 is driven to rotate, and the rotation of the rotating shaft 1103 drives the first rotating arm 1102 to rotate, and the rotation of the first rotating arm 1102 drives the second rotating section 111 at its end to rotate along the circumferential direction of the rotating shaft 1103. When the rotating shaft 1103 rotates, the ratchet 10131 coaxially mounted therewith is driven to rotate, and since the electromagnet 1332 is energized, the electromagnet 1332 attracts the iron column 1333, and the iron column 1333 drives the connecting piece 1334 to move, and the connecting piece 1334 drives the pawl 10132 to rotate, so that the pawl 10132 is separated from the ratchet 10131, and the ratchet 10131 can rotate freely. It can be seen that when the electromagnet 1332 is not energized, the rotating shaft 1103 is locked by the cooperation of the ratchet 10131 and the pawl 10132, that is, the first rotating arm 1102 is locked, which can be used to lock the angle of the first rotating arm 1102 when the power is off.
[0058] Similarly, after the main control module 51 controls the start of the driving motor 2, the driving motor 2 drives the driving gear 2 to rotate, the driving gear 2 drives the transmission gear 2 meshing therewith to rotate, the transmission gear 2 drives the rotating shaft 2 1113 to rotate, the rotating shaft 1113 rotates and drives the second rotating arm 1112 to rotate, and the second rotating arm 1112 drives the rotating wing mechanism at its end to rotate along the circumferential direction of the rotating shaft 2 1113, thereby adjusting the pitch angle of the rotating wing mechanism;
[0059] When the rotating shaft 1103 and the rotating shaft 2 1113 rotate, the brake shaft 1 1031 and the brake shaft 2 11123 connected thereto are driven to rotate, and the rotation angles of the rotating shaft 1103 and the rotating shaft 2 1113 are detected by the hollow shaft angle sensor 1 10141 and the hollow shaft angle sensor 2 11121 mounted on the brake shaft 1 11031 and the brake shaft 2 11123, and the angle information is transmitted to the main control module 51. The main processor processes the angle information, and when the set angle is reached, the drive motor 1 10121 and the drive motor 2 are controlled to stop rotating, and the angles of the first rotating section 110 and the second rotating section 111 are fixed; the brake shaft 1 11031 and the brake shaft 2 11123 are locked by the electromagnetic power-off brake 7 and the electromagnetic power-off brake 2 respectively, so that the first rotating section and the second rotating section can be kept from rotating when the power is off.
[0060] By controlling the electromagnetic power-off brake 7 to brake, the brake shaft 11031 is stopped, and the flip angle of the first rotating arm 1102 can be locked in cooperation with the driving motor 10121.
[0061] Since the driving motor 10121 is far away from the propeller, the torque borne by the driving motor 10121 is the largest, so an electromagnetic power-off brake 7 is installed to reduce the burden of the driving motor 10121;
[0062] Driving motor 1 10121 and driving motor 2 can adopt stepping motors to make angle control more precise. The flip and pitch angles of the rotor mechanism 2 can be adjusted through the cooperation of the first rotating section 110 and the second rotating section 111, which can enhance the maneuverability of the UAV and enable it to complete some difficult movements.
