Detailed Implementation

[0029] The following detailed description of specific embodiments of this application is based on the accompanying drawings. However, this description is not intended to limit this application, and modifications, substitutions, combinations, and deletions of the constituent elements in the technical solution can be made without departing from the spirit of this application. Furthermore, for ease of explanation, terms such as "up," "down," "forward," "backward," "left," and "right" are used to indicate direction, assuming a normally used state. However, these terms do not limit the usage state of the aircraft wingtip 1000 of this application.

[0030] (The overall structure of the aircraft's wingtip 1000)

[0031] like Figures 1-6 As shown, the wingtip 1000 of the aircraft is equipped with a navigation light 400, a wingtip body 100, a navigation light mounting bracket 200, and a wingtip mounting rib 300.

[0032] The navigation light 400 is roughly teardrop-shaped with a flat bottom and a curved top. A wiring harness (not shown) extends from the bottom of the navigation light 400. This wiring harness is connected to the aircraft body via a wiring harness channel described later, and is used for electrical control such as power supply and signal transmission of the navigation light 400.

[0033] The shape and type of the navigation light 400 are not limited to this embodiment, and any navigation light 400 in the art can be selected according to specific needs.

[0034] The wingtip body 100 has a streamlined shape with a continuously varying thickness. The wingtip body 100 is configured such that its base is elongated and teardrop-shaped, extending vertically upwards from the base and then narrowing in width while curving horizontally. A predetermined navigation light mounting position is provided above the surface of the wingtip body 100 near its top. A wiring channel 130 for the wiring harness of the navigation light 400 is formed inside the wingtip body 100. One end 131 of the wiring channel 130 opens at the navigation light mounting position of the wingtip body 100, and the other end 132 opens at the base of the foam 120 of the wingtip body 100.

[0035] The shape of the wingtip body 100 is not limited to this embodiment, and can be designed into any shape to consider specific aerodynamic requirements. In addition, the mounting position of the navigation light is not limited to this embodiment, and can be any position on the surface of the wingtip body 100. Regardless of how the navigation light mounting position is set, as long as one end 131 of the wiring channel 130 is open at the navigation light mounting position, the wiring harness connection of the navigation light 400 can be realized.

[0036] By setting up a wiring channel 130 as described above, space can be provided inside the wingtip body 100 for the wiring harness of the navigation lights, so that the wiring harness is not exposed outside the wingtip 1000. Therefore, not only will the aerodynamic efficiency of the wingtip 1000 not be affected, but the wiring harness can also be better protected, and the electrical control of the navigation lights 400 can be reliably performed.

[0037] The navigation light mounting bracket 200 is assembled at the navigation light mounting position of the wingtip body 100 for mounting the navigation light 400, and has a bracket cable passage 211 that communicates with one end 131 of the cable passage 130.

[0038] By setting up the navigation light mounting bracket 200 as described above, the replacement and maintenance of the navigation light 400 can be facilitated. For example, a suitable navigation light mounting bracket 200 can be selected according to the navigation light 400, thus ensuring compatibility with different types of navigation lights 400. Moreover, by providing a bracket cable pass 211 in the navigation light mounting bracket 200, the wiring harness of the navigation light 400 can pass through the bracket cable pass 211 into the cable passage 130 and smoothly connect to the main body of the aircraft when the wingtip 1000 is assembled.

[0039] The wingtip mounting rib 300 is used for mounting to the main body of the aircraft. The wingtip mounting rib 300 is assembled to the base of the wingtip main body 100 and has a rib passage 311 that communicates with the other end 132 of the passage 130.

[0040] By setting up the wingtip mounting rib 300 as described above, the various components of the aircraft wingtip 1000 can be assembled and disassembled as a whole relative to the aircraft body, making it convenient to replace and maintain the entire aircraft wingtip 1000. Moreover, by setting the rib wiring port 311 in the wingtip mounting rib 300, the wiring harness of the navigation light 400 can pass through the wiring channel 130 and the rib wiring port 311 smoothly to the aircraft body when the aircraft wingtip 1000 is assembled.

[0041] Here, this embodiment describes an example where the aircraft wingtip 1000 has a wingtip mounting rib 300, but it is also possible to have no wingtip mounting rib 300 and directly mount the aircraft wingtip 1000 to the aircraft body. Alternatively, the wingtip mounting rib 300 may form part of the aircraft body, and the aircraft wingtip 1000 may be attached to or detached from the wingtip mounting rib 300 of the aircraft body.

[0042] (Structure of the wingtip body 100)

[0043] like Figures 3-4As shown, the wingtip body 100 includes a skin 110 and a foam 120 wrapped by the skin 110. The material and manufacturing process of the wingtip body 100 are not limited, but from the perspective of low cost, lightweight and meeting structural stiffness requirements, the skin 110 is preferably made of carbon fiber composite material, and the wingtip body 100 is preferably formed by molding the skin 110 to wrap the foam 120 to form a full-height foam sandwich structure.

[0044] Foam 120 is composed of multiple (four in the figure) segmented foam 121. The assembly surface 122 of each segmented foam 121 is provided with grooves 123, for example by milling. In the assembled state of the segmented foam 121, two opposite grooves 123 are combined to form a wire passage 130.

[0045] By assembling multiple segmented foams 121 to form foam 120 as described above, each segmented foam 121 can be manufactured individually, thereby reducing the thickness specifications of the foam blank required to manufacture each segmented foam 121 and reducing costs. Furthermore, by utilizing the assembly surface 122 of the segmented foams 121 to form the wire passage 130, even if the shape of the wingtip body 100 is a complex curved surface, a meandering wire passage 130 can be easily formed inside the foam 120, reducing the processing difficulty of the wire passage 130.

[0046] Here, this embodiment describes an example where foam 120 is composed of multiple segmented foams 121. However, foam 120 can also be manufactured as a single unit. In this case, for example, a wire passage 130 can be drilled through the entire foam 120 after it has been formed. Regardless of how the wingtip body 100 is formed, as long as one end 131 of the wire passage 130 is open at the navigation light mounting position and the other end 132 is open at the base of foam 120, the function of connecting the wiring harness of the navigation light 400 to the aircraft body can be achieved.

[0047] Furthermore, the number of segmented foam 121 is not limited to four. As long as there are two or more segmented foam 121, the connecting surface 122 can be used to form the line channel 130. In addition, among the multiple segmented foam 121, there may also be segmented foam 121 that are not used to form the line channel 130.

[0048] Furthermore, this embodiment describes an example of forming a wire passage 130 using two grooves 123 with a semi-circular cross-sectional shape, but it is not limited to this. For example, a wire passage can also be formed by combining three grooves with a 120-degree arc cross-sectional shape. Alternatively, a wire passage with a D-shaped cross-section can be formed by combining grooves and planes. Moreover, it is not limited to forming a wire passage using grooves. For example, a wire passage with a polygonal cross-section can also be formed by combining multiple planes.

[0049] Regardless of the number, shape, or combination of the segmented foam 121, as long as the wire passage 130 is formed using at least a portion of the combined surface 122 of the segmented foam 121, a meandering wire passage 130 can be easily formed inside the combined foam 120.

[0050] (Structure of navigation light mounting bracket 200)

[0051] like Figure 5 As shown, the navigation light mounting bracket 200 includes a plate-shaped first mounting panel 210, an annular second mounting panel 220, and a transition support portion 230 connecting the outer edge of the first mounting panel 210 and the inner edge of the second mounting panel 220. The material of the navigation light mounting bracket 200 is not limited, but from the perspectives of low cost, lightweight, and meeting structural rigidity requirements, the navigation light mounting bracket 200 is preferably made of carbon fiber composite material.

[0052] The first mounting panel 210 is for mounting the navigation light 400. The bottom surface of the navigation light 400 serves as the mounting surface connected to the first mounting panel 210, and has a navigation light wiring harness port 401 and a navigation light mechanical interface 402. A wiring harness (not shown) extends from the navigation light wiring harness port 401. The first mounting panel 210 has a bracket cable pass-through port 211 communicating with the navigation light wiring harness port 401, and a support nut 501 corresponding to the navigation light mechanical interface 402 is fixed to the surface opposite to the mounting side of the navigation light 400. The navigation light 400 is mounted to the navigation light mounting bracket 200 by connecting bolts through the navigation light mechanical interface 402 and the first mounting panel 210 to the support nut 501.

[0053] By using the support plate nut 501, when installing or removing the navigation light 400 relative to the navigation light mounting bracket 200, the bolts only need to be operated from the side of the navigation light 400, improving operational convenience. For example, with the navigation light mounting bracket 200 assembled to the wingtip body 100, the navigation light 400 can be installed or removed without removing the navigation light mounting bracket 200. Furthermore, the shape of the first mounting panel 210, the number and position of the support plate nuts 501, and the position of the bracket cable passage 211 can be adjusted according to the navigation light 400, thereby ensuring compatibility with different types of navigation lights 400. In addition, the use of connectors such as bolts and support plate nuts 501 is not limited to; any known connector or connection method can be used.

[0054] The second mounting panel 220 is mounted at a predetermined navigation light mounting position. The skin 110 of the wingtip body 100 has a recessed step 111 at the navigation light mounting position that corresponds to the shape of the second mounting panel 220. The second mounting panel 220 is glued to the recessed step 111.

[0055] By providing a recessed step 111 on the skin 110, the outer surface of the wingtip body 100 can be flush with the outer surface of the navigation light mounting bracket 200 when the navigation light mounting bracket 200 is assembled to the wingtip body 100, thus improving aerodynamic efficiency. However, the recessed step 111 can also be omitted, and the second mounting panel 220 can be directly mounted at the navigation light mounting position. Furthermore, it is not limited to adhesive bonding; any known connector or connection method can be used.

[0056] The navigation light mounting bracket 200, which has a first mounting panel 210, a second mounting panel 220 and a transition support 230, can provide the space required for fixing the mounting plate nut 501 and other connecting parts in the area surrounded by the transition support 230. Furthermore, in the assembled state of the aircraft wingtip 1000, the connecting parts are not exposed to the outside and the aerodynamic efficiency of the aircraft wingtip 1000 is not affected.

[0057] The structure of the navigation light mounting bracket 200 described in this embodiment is only one example. Any other structure can be used as long as the navigation light 400 can be mounted on the wingtip body 100.

[0058] (Structure of wingtip mounting rib 300)

[0059] like Figure 6 As shown, the wingtip mounting rib 300 includes a rib body 310, a first flange 320, and a second flange 330. The material of the wingtip mounting rib 300 is not limited, but from the perspectives of low cost, lightweight, and meeting structural rigidity requirements, the wingtip mounting rib 300 is preferably made of carbon fiber composite material or aluminum alloy.

[0060] The rib body 310 is plate-shaped, corresponding to the shape of the base of the wingtip body 100, and has a rib passage opening 311. The rib passage opening 311 is elongated and communicates with the other end 132 of the passage channel 130 when the wingtip mounting rib 300 is assembled to the wingtip body 100. The rib body 310 is also preferably provided with a weight reduction hole 312 to achieve weight reduction of the aircraft wingtip 1000.

[0061] The first flange 320 extends from the outer edge of the rib body 310 in a direction perpendicular to the plate surface of the rib body 310. The first flange 320 is embedded in the skin 110 at the base of the wingtip body 100. A support nut 502 is fixed to the inner side of the first flange 320 opposite to the skin 110. The wingtip mounting rib 300 is assembled to the wingtip body 100 by connecting bolts through the skin 110 and the first flange 320 to the support nut 502. Here, this embodiment shows an example of a ring of support nuts 502 arranged in a circular pattern at the same height of the first flange 320, but the number and layout of the support nuts 502 are not limited to this. For example, the heights at which multiple support nuts 502 are configured may also be different.

[0062] The second flange 330 extends from the outer edge of the rib body 310 toward the side opposite to the first flange 320 in a direction perpendicular to the plate surface of the rib body 310. The second flange 330 is used for installation onto the aircraft body.

[0063] Based on the wingtip mounting rib 300 described above, by embedding the first flange 320 into the skin 110 and using the support nut 502, when assembling or disassembling the wingtip body 100 relative to the wingtip mounting rib 300, the bolts only need to be operated from the skin 110 side of the wingtip body 100, thus improving operational convenience. For example, with the wingtip mounting rib 300 assembled to the aircraft body, the wingtip body 100 can be assembled or disassembled without removing the wingtip mounting rib 300.

[0064] Furthermore, it is not limited to embedding the first flange 320 within the skin 110; as long as the first flange 320 is installed at the base of the wingtip body 100, the connection between the rib cable passage 311 and the other end 132 of the cable passage 130 can be achieved. For example, the first flange 320 can also be sleeved over the base of the wingtip body 100. Moreover, it is not limited to using fasteners such as bolts and bracket nuts 502; any known fasteners or connection methods can be used.

[0065] The structure of the wingtip mounting rib 300 described in this embodiment is only one example; any other structure can be used as long as it can be installed on the main body of the aircraft.

[0066] (Manufacturing method of aircraft wingtip 1000)

[0067] Next, the manufacturing method of the aircraft wingtip 1000 according to this embodiment will be described.

[0068] The manufacturing method includes the steps of preparing the wingtip body 100, assembling the navigation light mounting bracket 200, assembling the wingtip mounting rib 300, and installing the navigation light 400.

[0069] In the process of preparing the wingtip body 100, multiple segmented foams 121 are manufactured, and the assembly surfaces 122 of the segmented foams 121 are milled to form grooves 123. Then, the multiple segmented foams 121 are assembled to form foam 120. At this time, the grooves 123 are used to form a cable passage 130, with one end 131 of the cable passage 130 opening at a predetermined navigation light mounting position on the wingtip body 100, and the other end 132 opening at the base of the foam 120 of the wingtip body 100. Subsequently, the skin 110 is used to wrap the foam 120 to form a full-height foam sandwich structure wingtip body 100, and an opening is made in the skin 110 at the position corresponding to one end 131 of the cable passage 130.

[0070] During the assembly of the navigation light mounting bracket 200, the second mounting panel 220 is glued to the recessed step 111 of the skin 110. At this time, the bracket cable passage 211 is connected to one end 131 of the cable passage 130.

[0071] In the assembly process of the wingtip mounting rib 300, the first flange 320 of the wingtip mounting rib 300 is embedded in the skin 110 at the base of the wingtip body 100. Bolts are passed through the skin 110 and the first flange 320 and connected to the support nut 502 fixed on the inner side of the first flange 320 opposite to the skin 110. At this time, the rib wire passage 311 is connected to the other end 132 of the wire passage 130.

[0072] In the process of installing the navigation light 400, bolts are passed through the navigation light 400 and the first mounting panel 210 and connected to the bracket nut 501 fixed on the surface of the first mounting panel 210 opposite to the mounting side of the navigation light 400, and the wiring harness of the navigation light 400 is passed through the bracket wire passage 211, the wire passage 130 and the rib wire passage 311.

[0073] In the above manufacturing method, the order of each process is not limited, and this application is not limited to the above manufacturing method. For example, if the wingtip mounting rib 300 is not present, the process of assembling the wingtip mounting rib 300 may also be omitted.

It should be understood that such modifications and variations are included therein as long as they do not depart from the scope of the appended claims.
