[0023] Combination Figures 3 to 16 As shown, a bracket device for fixing the tail fin of a UAV includes two frame bodies 1 spaced apart from each other, the gap between the two frame bodies 1 forming an accommodating space for the tail fin body 100; each frame body 1 includes an upper crossbeam 1a and a lower crossbeam 1b spaced apart vertically, and a diagonal beam 1c is welded to the front end of the upper crossbeam 1a and the lower crossbeam 1b; a plurality of support plates 2 are welded between the lower crossbeams 1b of the two frame bodies 1, the support plates 2 being used to support the bottom edge of the tail fin body 100; Multiple tail fin fixing plates 3 are installed between the inclined beams 1c of the two frame bodies 1 by screws. The tail fin fixing plates 3 are used to be screwed to the fixing hole plate 101 of the tail fin body 100. A trailing edge mounting plate 4 and a trailing edge center support plate 5 are installed between the upper crossbeams 1a of the two frame bodies 1 by screws. The trailing edge mounting plate 4 is used to support the connecting lug plate 201 of the wing trailing edge 200 and is screwed to the connecting lug plate 201. The trailing edge center support plate 5 is used to support the middle part of the bottom surface of the wing trailing edge 200.

[0024] Combination Figures 13 to 16As shown, by adopting the above structure, when loading the tail fin body 100 and the wing trailing edge 200, first remove the trailing edge mounting plate 4, the trailing edge center support plate 5, and the tail fin fixing plate 3. At this time, the upper part and front end of the entire bracket device are open, which makes it easy to hoist the tail fin body 100 into the gap between the two frame bodies 1. After placing the tail fin body 100 into the gap between the two frame bodies 1, the support plate 2 provides support for the bottom of the tail fin body 100. Adjust the position of the tail fin body 100, and connect and fix the tail fin fixing plate 3 to the fixing hole plate 101 on the tail fin body 100 with screws. Then, fix both ends of the tail fin fixing plate 3 to the inclined beam 1c with screws. This completes the loading and fixing of the tail fin body 100. Next, the trailing edge mounting plate 4 and the trailing edge center support plate 5 are fixed to the upper crossbeam 1a of the two frame bodies 1 with screws. Then, the wing trailing edge 200 is loaded, and the connecting lug 201 of the wing trailing edge 200 is placed on the trailing edge mounting plate 4 and fixed with screws. At the same time, the trailing edge center support plate 5 is used to support the wing trailing edge 200 at the middle position of the bottom surface. Thus, the wing trailing edge 200 is fixedly installed on the bracket device. After the bracket device is loaded with the tail fin body 100 and the wing trailing edge 200, the resulting integrated structure can be placed in a container for transportation.

[0025] Combination Figure 3 , Figure 5 As shown, to better support the tail fin body 100, the number of support plates 2 is at least three. Each support plate 2 has a concave block 7 on its top surface, and the top surface of the concave block 7 has a concave support groove for supporting and engaging with the lower edge of the tail fin body 100, thus providing good support. Furthermore, to prevent rigid contact between the tail fin body 100 and the concave block 7 and to protect the tail fin body 100, vibration damping pads 8 are adhered to the concave support grooves of the concave blocks 7.

[0026] Combination Figure 3 , Figure 5As shown, the frame body 1 also includes multiple vertical rods 1d and multiple first diagonal braces 1e and second diagonal braces 1f. The multiple vertical rods 1d are arranged in parallel and spaced apart. The upper end of the vertical rod 1d is welded to the upper crossbeam 1a, and the lower end is welded to the lower crossbeam 1b. A first diagonal brace 1e is arranged between two adjacent vertical rods 1d. The upper end of the first diagonal brace 1e is welded to the intersection of one of the vertical rods 1d and the upper crossbeam 1a, and the lower end is welded to the intersection of the other vertical rod 1d and the lower crossbeam 1b. The upper part of the diagonal beam 1c extends beyond the upper crossbeam 1a. To increase stability, a second diagonal brace 1f is welded between the top of the diagonal beam 1c and the upper crossbeam 1a. By utilizing the vertical rods 1d, the first diagonal braces 1e, and the second diagonal braces 1f, the entire frame body 1 is made more stable. Furthermore, in order to increase the stability of the entire bracket device, connecting rods 9 are welded between the front and rear ends of the lower crossbeams 1b of the two frame bodies 1 respectively; multiple connecting rods 9 are welded between the vertical rods 1d at the rear ends of the two frame bodies 1; and multiple connecting rods 9 are welded between the rear ends of the upper crossbeams 1a of the two frame bodies 1.

[0027] Combination Figure 7 As shown, the tail fin fixing plate 3 has a protruding boss 3a in the middle, and the two end faces of the boss 3a form limiting surfaces for engaging between the inclined beams 1c of the two frame bodies 1. The two ends of the boss 3a extend to form flange plates 3b, which are used to rest on the inclined beams 1c and are screwed together with the inclined beams 1c. When loading the tail fin body 100, since the tail fin fixing plate 3 is first connected and fixed to the fixing hole plate 101 on the tail fin body 100 with screws, an adjusting shim 10 is provided between the flange plate 3b and the inclined beam 1c to facilitate the screw connection between the tail fin fixing plate 3 and the inclined beam 1c. By using adjusting shims 10 of different thicknesses, it is easier to screw the tail fin fixing plate 3 and the inclined beam 1c together.

[0028] Combination Figure 8 , Figure 14 As shown, a groove 4a is provided on the top surface of the trailing edge mounting plate 4 to support the connecting lug 201 of the wing trailing edge 200. A threaded hole is provided on the bottom of the groove 4a. After the connecting lug 201 is placed on the groove 4a of the trailing edge mounting plate 4, the screw passes through the connecting lug 201 and is screwed into the threaded hole of the groove 4a to fix it.

[0029] Combination Figure 8 and Figure 13 , Figure 15 As shown, a limiting groove 5a is provided on the top surface of the support plate 5 in the trailing edge to support and engage with the bottom center of the wing trailing edge 200. The limiting groove 5a serves to limit the movement of the wing trailing edge 200.

[0030] Combination Figure 3 , Figure 5 , Figure 15 and Figure 16 As shown, in order to better support the wing trailing edge 200, a trailing edge rear support plate 6 is also installed between the upper crossbeams 1a of the two frame bodies 1 by screws. The trailing edge rear support plate 6 is used to support the bottom surface of the rear part of the wing trailing edge 200 and is connected to the wing trailing edge 200 by screws.

[0031] Combination Figure 3 , Figure 4 and Figure 11 As shown, a bearing support plate 11 is welded onto the lower crossbeam 1b, and a rolling bearing 12 is rotatably mounted on the bearing support plate 11. The bearing support plate 11 and the rolling bearing 12 are connected by a pin 13. The pin 13 passes through the rolling bearing 12 and the bearing support plate 11 in sequence and is screwed onto a nut 14. A cotter pin 15 is provided between the nut 14 and the pin 13. By providing the rolling bearing 12, the entire bracket assembly is made easier to slide inside the container when it is loaded into the container.

[0032] Combination Figure 3 , Figure 4 and Figure 12 As shown, the bracket assembly also includes a locking block 16, which has an arc-shaped engaging portion 16a and a bolt mounting portion 16b, with bolt through holes provided on the bolt mounting portion 16b. Once the bracket assembly has moved to its designated position inside the container, the locking block 16 locks the entire assembly in place. Specifically, the bolt mounting portion 16b is fixed to the container by bolts, and the arc-shaped engaging portion 16a has an arc-shaped surface for engaging with the outer circumferential surface of the rolling bearing 12 to achieve locking.
