Therefore, it should not be understood as limiting the scope of protection of this application.

[0028] The following is combined with Figure 1 This application is described in further detail.

[0029] The present application provides a lightweight integral I-shaped wing-body docking diffuser structure, comprising: a first docking diffuser portion 1, a second docking diffuser portion 2 and an I-shaped connecting portion 3.

[0030] Specifically, such as Figure 1 As shown, the first docking diffuser 1 is a plate-like structure with a predetermined curvature, including one or more. When there are multiple first docking diffusers 1, two adjacent first docking diffusers 1 are connected as a whole through an I-shaped connecting portion 3; the second docking diffuser 2 is a plate-like structure with a predetermined curvature, including two. The two second docking diffusers 2 are symmetrically arranged at both ends of the first docking diffuser 1, and the second docking diffuser 2 and the first docking diffuser 1 are connected as a whole through an I-shaped connecting portion 3; the cross-section of the I-shaped connecting portion 3 is I-shaped. During assembly, the integral I-shaped wing-fuselage docking diffuser structure formed by the first docking diffuser 1, the second docking diffuser 2 and the I-shaped connecting portion 3 is fitted on the wing-fuselage docking frame through the I-shaped connecting portion 3. The position of the I-shaped connecting portion 3 corresponds to the position of the wing spar. One side of the integral I-shaped wing-fuselage docking diffuser structure is glued to the wing-fuselage docking frame, and the other side is glued to the fuselage wall panel.

[0031] In one embodiment of the present application, see Figure 1The integral I-shaped wing-body docking diffuser structure includes a first docking diffuser 1 and two second docking diffusers 2, wherein one second docking diffuser 2 is arranged at the first end of the first docking diffuser 1 and is connected to the first docking diffuser 1 through an I-shaped connecting portion 3; the other second docking diffuser 2 is arranged at the second end of the first docking diffuser 1 and is connected to the first docking diffuser 1 through an I-shaped connecting portion 3.

[0032] It is understandable that the lightweight integral I-shaped wing-body docking diffuser structure of the present application is not limited to the specific structural form in the above-mentioned embodiment. The number of I-shaped connecting parts 3 can also be adjusted as needed according to the number of wing spars, that is, the I-shaped connecting parts 3 can be increased by increasing the number of first docking diffusers 1. In another embodiment of the present application, the integral I-shaped wing-body docking diffuser structure includes two first docking diffusers 1 and two second docking diffusers 2, wherein the two first docking diffusers 1 are connected as a whole through the I-shaped connecting part 3; one second docking diffuser 2 is arranged at the first end of the integral structure composed of the two first docking diffusers 1, and is connected to the first docking diffuser 1 through the I-shaped connecting part 3; another second docking diffuser 2 is arranged at the second end of the integral structure composed of the two first docking diffusers 1, and is connected to the first docking diffuser 1 through the I-shaped connecting part 3. By analogy, when the number of I-shaped connecting parts 3 needs to be increased, it is only necessary to add a corresponding number of first docking diffusers 1, and the multiple first docking diffusers 1 can be designed to have different lengths.

[0033] In a preferred embodiment of the present application, the integral I-shaped wing-body docking diffuser structure is integrally formed using an integral carbon fiber composite material laminate structure.

[0034] In a preferred embodiment of the present application, assembly holes are provided on the first docking diffuser 1 , the second docking diffuser 2 and the X-shaped connecting portion 3 to assist in the assembly of the wing-body docking frame or the fuselage panel.

[0035] In a preferred embodiment of the present application, the horizontal projection of the first butt-diffuser portion 1 is rectangular, while the horizontal projection of the second butt-diffuser portion 2 is trapezoidal. It is understood that the structural shapes of the first butt-diffuser portion 1 and the second butt-diffuser portion 2 can be selected based on practical needs. In this embodiment, the two second butt-diffuser portions 2 have different lengths.

[0036] The lightweight integral "X"-shaped wing-body docking diffusion structure of the present application can diffuse the concentrated load transmitted from the wing to the fuselage wall panel, meeting the need for load diffusion at the wing-body docking point.

[0037] The lightweight, integral, "X"-shaped wing-fuselage docking and diffusion structure proposed in this application boasts exceptional integrity, distributing loads at the wing-fuselage docking point with a single component. While meeting installation and load-bearing requirements, it features a simple design, mature manufacturing methods, a limited number of connectors, low weight, low cost, and ease of manufacturing and assembly, demonstrating significant practical application value. This application has been successfully deployed on a certain unmanned aerial vehicle (UAV) and an all-composite general-purpose aircraft, achieving excellent results.

[0038] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
