[0122] <Outline of the frame assembly 1>

[0123] Hereinafter, a frame assembly 1 for an unmanned aircraft according to an embodiment of the present utility model will be described. The frame assembly 1 of this embodiment has a structure for fixing a fixing member to a plurality of frame members. The raw material of the frame member is, for example, CFRP (Carbon Fiber Reinforced Plastic). The raw material of the fixing member can also be CFRP. By setting the fixing member as a plate shape and fixing it to a plurality of frame members, the rigidity of the frame assembly 1 can be ensured. Alternatively, a rod-shaped fixing member can be used as a diagonal brace (Japanese:筋交い) and placed between a plurality of frame members to ensure the rigidity of the frame assembly 1.

[0124] In addition, the fixing member can be riveted and fixed to the frame member. Thereby, mechanisms such as jigs can be omitted, and the weight reduction of the frame assembly 1 can be achieved. Two rivets can be arranged at two positions for one frame member.

[0125] In addition, by setting the fixing member as a plate shape, the frame member can be clamped by two fixing members. Thereby, the rigidity in the vertical direction (the clamping direction) of the frame assembly 1 can be ensured. An opening can be provided in at least one of the plate-shaped fixing members. Thereby, the weight reduction of the frame assembly 1 is achieved, and it is convenient to arrange various components in the opening.

[0126] <Structure of the frame assembly 1>

[0127] Figure 1 It is a top view of the frame assembly 1 of this embodiment. Figure 1 The frame assembly 1 of the example can be used for an unmanned aircraft flying in the forward direction indicated by the arrow symbol F. The frame assembly 1 includes two parallel frame members 211 and 212 extending in the left-right direction perpendicular to the front-rear direction. Frame members 221 and 222 parallel to the front-rear direction are arranged at one end of the frame members 211 and 212. Frame members 223 and 224 parallel to the front-rear direction are arranged at the other end of the frame members 211 and 212. In addition, between the frame members 211 and 212, frame members 225 and 226 extending parallel to the front-rear direction are provided at a distance from the ends of the frame members 211 and 212. Alternatively, frame members 213 and 214 parallel to the left-right direction can be provided respectively from the frame members 225 and 226 toward the outside of the frame assembly 1.

[0128] Plate-shaped fixing members 31 and 32 are disposed at the left and right ends of the frame assembly 1. The fixing member 31 is fixed to the frame members 211, 212, 213, 221, 222, 225 by rivets 40 at the edge position of the fixing member 31 and the middle position in the front-back direction along the frame members 211, 212, 213, 221, 222, 225. The fixing member 31 is fixed to the frame members 211, 212, 213, 221, 222, 225 by rivets 40 at a plurality of locations. Similarly, the fixing member 32 is fixed to the frame members 211, 212, 214, 223, 224, 226 by rivets 40 at the edge position of the fixing member 32 and the middle position in the front-back direction along the frame members 211, 212, 214, 223, 224, 226. An opening 11 is formed in the central portion of the frame assembly 1. When the frame assembly 1 is used for a flying object, various payloads can be placed in the opening 11 .

[0129] Figure 2 It is a plan view of the frame assembly 1 according to the present embodiment. Figure 2 In the example, Figure 1 The frame assembly 1 shown has fixing members 33 and 34 disposed opposite to the fixing members 31 and 32. The frame members 211, 212, 213, 221, 222, and 225 are sandwiched by the fixing members 31 and 33. Similarly, the frame members 211, 212, 223, 224, and 226 are sandwiched by the fixing members 32 and 34. The fixing member 33 is fixed to the frame members 211, 212, 213, 221, 222, and 225 at multiple locations by rivets 40. Similarly, the fixing member 34 is also fixed to the frame members 211, 212, 223, 224, and 226 at multiple locations by rivets 40.

[0130] Figure 3 yes Figure 2 AA cross-sectional view. It shows that the fixing members 31 and 33 are fixed to the frame member 222 by the rivet 40 and are also fixed to the frame member 213 by the rivet 40. The ends of each frame member can be separated from the other frame members, such as Figure 3 In the example, a gap 12 is also provided between the end 2221 of the frame member 222 and the frame member 213. Figure 2 , the fixing member 33 is provided with openings 331 and 332. Figure 2In the top view of the frame assembly 1, the fixing member 31 can be observed from the openings 331 and 332. Similarly, the fixing member 34 is provided with openings 341 and 342, and the fixing member 32 can be observed from above the frame assembly 1 through the openings 341 and 342. When the frame assembly 1 is used for an aircraft, a control mechanism or the like can be arranged in the openings 331, 332, 341, 342.

[0131] Figure 4 1 is a diagram for explaining another structural example of the frame assembly 1. Figure 4 As shown, the fixing member 3 fixing the plurality of frame members 21 and 22 can be set to a triangle instead of a rectangle. In addition, the fixing member 3 can be set to any shape. Here, the fixing member 3 is riveted and fixed to the fixing frame members 21 and 22 at a plurality of locations by rivets 40, respectively.

[0132] Figure 5 1 is a diagram for explaining another structural example of the frame assembly 1. Figure 5 As shown, the longitudinal directions of the plurality of frame members 21 and 22 may not be perpendicular. Figure 5 In the example of FIG. 1 , the fixing member 3 is riveted and fixed to the frame members 21 and 22 at multiple locations by rivets 40. Figure 5 As shown, it is also possible to fix the two frame members 21 and 22 with rivets 40 (P) without providing a gap between the two frame members 21 and 22. Figure 1 , Figure 2 In the frame assembly 1 shown, the end portions of a part or all of the frame members may be fixed to other frame members.
