[0011] <Outline of frame assembly 1> Hereinafter, a frame assembly 1 for an unmanned aerial vehicle according to one embodiment of the present invention will be described. The frame assembly 1 of this embodiment has a structure for fixing a fixing member to a plurality of frame members.

[0012] The frame members are made of, for example, carbon fiber reinforced plastic (CFRP). The fixing members can also be made of CFRP. The fixing members can be made in a plate shape and fixed to multiple frame members to ensure the rigidity of the frame assembly 1. The rigidity of the frame assembly 1 can also be ensured by using rod-shaped fixing members as diagonal braces to span between multiple frame members.

[0013] Furthermore, the fixing members can be riveted to the frame members, which makes it possible to omit mechanisms such as clamps, thereby reducing the weight of the frame assembly 1. Rivets can be placed in two locations on one frame member.

[0014] Also, the fixing member can be plate-shaped, and the frame member can be sandwiched between two fixing members. This ensures the rigidity of the frame assembly 1 in the vertical direction (the clamping direction). An opening can be provided on one side of the plate-shaped fixing member. This reduces the weight of the frame assembly 1 and makes it easy to place various parts, etc., in the opening. <Configuration of frame assembly 1> FIG. 1 is a top view of a frame assembly 1 of this embodiment. The frame assembly 1 of the example of FIG. 1 can be used for an unmanned aerial vehicle that flies with the direction of the arrow F as the forward direction. The frame assembly 1 includes two parallel frame members 211 and 212 extending in a left-right direction perpendicular to the front-rear direction. At one end of the frame members 211 and 212, frame members 221 and 222 parallel to the front-rear direction are arranged. At the other end of the frame members 211 and 212, frame members 223 and 224 parallel to the front-rear direction are arranged. In addition, frame members 225 and 226 are provided between the frame members 211 and 211, extending parallel to the front-rear direction at a distance from the ends of the frame members 211 and 211. In addition, frame members 213 and 214 parallel to the left-right direction may be provided from the frame members 225 and 226 toward the outside of the frame assembly 1, respectively.

[0015] Plate-shaped fixing members 31 and 32 are disposed on the left and right ends of the frame assembly 1. The fixing member 31 is fixed to each of the frame members 211, 212, 213, 221, 222, and 215 by rivets 40. The fixing member 31 is riveted at multiple locations to each of the frame members 211, 212, 213, 221, 222, and 215. Similarly, the fixing member 32 is fixed at multiple locations to each of the frame members 211, 212, 214, 223, 224, and 216 by rivets 40. An opening 11 is formed in the center of the frame assembly 1. When the frame assembly 1 is used in an aircraft, various payloads can be placed in this opening 11.

[0016] Fig. 2 is a top view of the frame assembly 1 of this embodiment. In the example of Fig. 2, fixing members 33 and 34 are further arranged opposite to the fixing members 31 and 32 of the frame assembly 1 shown in Fig. 1. The frame members 211, 212, 213, 221, 222, and 225 are sandwiched between the fixing members 31 and 33. Similarly, the frame members 211, 212, 223, 224, and 226 are sandwiched between the fixing members 32 and 34. The fixing member 33 is fixed to each of the frame members 211, 212, 213, 221, 222, and 225 at multiple locations by the rivets 40. Similarly, the fixing member 34 is fixed to each of the frame members 211, 212, 223, 224, and 226 at multiple locations by the rivets 40.

[0017] Fig. 3 is a cross-sectional view taken along line AA in Fig. 2. The fixing members 31 and 33 are shown to be fixed to the frame member 222 with a rivet 40, and are also fixed to the frame member 213 with a rivet 40. The end of each frame member may be spaced apart from the other frame members, and in the example of Fig. 3, a gap 12 is provided between the end 2221 of the frame member 222 and the frame member 213.

[0018] Returning to Fig. 2, frame member 33 is provided with openings 331 and 332. Therefore, in the top view of Fig. 2, fixed member 31 is visible from openings 331 and 332. Similarly, frame member 33 is provided with openings 341 and 342, and fixed member 32 is visible from above frame assembly 1 through openings 341 and 342. When frame assembly 1 is used in an aircraft, it is possible to arrange, for example, a control mechanism in openings 331, 332, 341, 342.

[0019] Fig. 4 is a diagram for explaining another configuration example of the frame assembly 1. As shown in Fig. 4, the fixing member 3 that fixes the multiple frame members 21 and 22 can be triangular rather than rectangular. Also, the fixing member 3 can be of any shape. Here too, the fixing member 3 is fixed to each of the frame members 21 and 22 by rivets 40 at multiple points.

[0020] FIG. 5 is a diagram for explaining another configuration example of the frame assembly 1. As shown in FIG. 5, the longitudinal direction of the multiple frame members 21 and 22 does not have to be perpendicular. In the example of FIG. 5, the fixing member 3 is riveted to each of the frame members 21 and 22 at multiple locations with rivets 40. As shown in FIG. 5, it is also possible to fix the two frame members 21 and 22 with rivets 40 (P) without providing a gap between them. In the frame assembly 1 shown in FIG. 1 and FIG. 2, the ends of some or all of the frame members may also be fixed to other frame members.

[0021] Although the present embodiment has been described above, the above embodiment is intended to facilitate understanding of the present invention, and is not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit of the present invention, and equivalents thereof are also included in the present invention.
