[0021] Specifically, positioning holes 2 are drilled at the four corners of the top surface of the gimbal 1, and are fixedly connected to the bottom end of the drone body by positioning bolts, so as to facilitate initial installation.

[0022] Specifically, the fixing plate 16 is adhesively fixed to the bottom surface of the shooting box 3, and connecting screw holes are tapped at the four corners of the upper end surface of the fixing plate 16 located outside the shooting box 3. One end of the connecting plate 10 is a semicircular structure, and the other end is a rectangular structure, and the four corners of the rectangular structure are also tapped with connecting screw holes, and the fixing plate 16 is detachably connected to the fixing plate 16 through the connecting screw holes of the fixing plate 16 by fixing bolts 17.

[0023] Specifically, the top of the fixed end of the first motor 11 is embedded and fixed in the bottom end surface of the semicircular structure of the connecting plate 10, and the output shaft of the first motor 11 is fixedly connected to the top of the guide bracket 12, so that the first motor 11 can rotate and drive the fine adjustment of the horizontal angle of the guide bracket 12 and the casing 8.

[0024] Specifically, the guide bracket 12 is a U-shaped rod structure, and a semicircular protrusion 20 protrudes to one side in the middle of the horizontal top of the guide bracket 12, and a bottom hole for placing the output shaft of the first motor 11 is opened at the center of the top surface of the protrusion 20. The bottom end of one side of the two groups of end legs of the guide bracket 12 is opened with a socket 19, one group of which is hingedly connected to the outer side of the casing 8 through a pin shaft, and the output shaft of the third motor 18 fixedly connected to the outer side of the casing 8 is inserted into the other group of sockets 19, and the third motor 18 is fixed on the side of the guide bracket 12, so that when the third motor 18 rotates, the vertical angle of the casing 8 can be fine-tuned. At the same time, the first motor 11, the second motor 14, and the third motor 18 are all servo motors, which can realize forward and reverse motion.

[0025] Specifically, the bottom end of the casing 8 is sealed with a bottom cover 13 by screws and can be disassembled later. Two groups of second motors 14 are embedded and fixed on the inner wall of the casing 8, and the first guide support rod 5 and the second guide support rod 6 are both L-shaped structures, wherein both ends of the L-shaped structure of the first guide support rod 5 and the second guide support rod 6 are arc-shaped structures and have arc-shaped through holes.

[0027] Working principle: When using the drone fill light device, the operator first fixes and connects the various components of the new drone fill light device according to corresponding needs, and then fixes the gimbal 1 at the bottom position of the drone body. When flying at night, the two groups of fill lights 7 fill light the shooting of the camera 4 in the shooting box 3 during the shooting process. At the same time, when it is necessary to adjust the distance between the two groups of fill lights 7 (that is, the distance between the camera 4), the two groups of second motors 14 in the box are started to work. Here, the two groups of second motors 14 can be started separately. The second motor 14 rotates, driving the transmission shaft 15 to rotate, thereby driving the first guide on the transmission shaft 15 fixedly connected to the transmission shaft 15. When the support rod 5 or the second guide support rod 6 rotates, and the first guide support rod 5 and the second guide support rod 6 rotate, it will drive another group of first guide support rods 5 and another group of second guide support rods 6 to rotate on another group of transmission shafts 15, and then drive the rotation of the fill light 7 to achieve arc movement of the fill light 7. At the same time, the first motor 11 and the third motor 18 can also be started to rotate. The rotation of the first motor 11 drives the horizontal rotation of the guide bracket 12 and the casing 8 to adjust the horizontal angles of the two groups of fill lights 7. The rotation of the third motor 18 drives the casing 8 to rotate in the guide bracket 12, and fine-tunes the vertical angles of the casing 8 and the two groups of fill lights 7 until the fill light requirements of the fill lights 7 are adjusted.
