[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figure 1-3 As shown, a low-cost integrated UAV aileron fixed connection structure includes an aileron shaft 5, an aileron reinforcement rib 2 and a wing reinforcement rib 1;

[0026] The aileron reinforcement ribs 2 are provided in multiple groups, and the aileron reinforcement ribs 2 are fixedly mounted below the aileron shaft 5 through the shaft fixing member 4;

[0027] An aileron connecting plate 3 is installed above the aileron shaft 5, and a wing reinforcement rib 1 is fixed on the top of the aileron connecting plate 3;

[0028] When working, the number, size and thickness of the aileron connecting plate 3 and the shaft fixing part 4 can be changed at will according to the length and strength requirements of the aileron. The parts of each part are installed in place through the drone assembly tooling. When assembling the aileron, the aileron reinforcing rib 2, the aileron connecting plate 3 and the shaft fixing part 4 are passed through the tooling on the aileron shaft 5. Because there is no aileron end rib fixing space and mounting structure on the wing, the entire aileron is in a suspended state. First, the shaft fixing part 4 is used to fix the aileron reinforcing rib 2 and the aileron shaft 5 to prevent the aileron shaft 5 from moving left and right during rotation, causing the aileron shaft 5 to fall off. The aileron connecting plate 3 and the aileron shaft 5 are clearance-matched to ensure that the aileron shaft 5 can rotate. The aileron connecting plate 3 is positioned to the position of the wing reinforcing rib 1. The aileron connecting plate 3 needs to detect the web surface of the wing reinforcing rib 1 and fit with it, and then fasteners are used to connect and fix it. The overall connection structure of the device is simple, meets the low-cost use requirements, and is convenient to install and disassemble, thereby improving the disassembly and assembly efficiency.

[0029] The rotating shaft fixing part 4 is formed as a whole by a sliding sleeve and a connecting plate, and the rotating shaft fixing part 4 is connected and fixed to the aileron rotating shaft 5 and the aileron reinforcement rib 2 respectively through a fixing bolt 6; during operation, the rotating shaft fixing part 4, the aileron rotating shaft 5 and the aileron reinforcement rib 2 are connected and fixed by a fixing bolt 6 to prevent the rotating shaft from moving and facilitate the disassembly and replacement of the aileron reinforcement rib 2.

[0030] The bottom of the aileron connecting plate 3 is slidably sleeved on the aileron rotating shaft 5, and the upper part of the aileron connecting plate 3 is connected and fixed to the aileron reinforcing rib 2 by the fixing bolt 2 7; during operation, the aileron connecting plate 3 is connected and fixed to the aileron reinforcing rib 2 by the fixing bolt 2 7 to support the rotation of the aileron and facilitate the disassembly and maintenance of the entire device.

[0031] The wing reinforcement ribs 1 and aileron reinforcement ribs 2 are both made of composite materials. During operation, the composite materials maintain a lightweight structure while exhibiting excellent strength and rigidity. They possess high tensile strength, bending resistance, and fatigue resistance, enabling them to withstand heavy loads and ensure the reliability of the device in high-intensity operating environments. This improves the device's structural safety and extends its service life. Furthermore, mold-laying molding shortens the production cycle, significantly improves production efficiency, and effectively reduces material waste during the manufacturing process, further reducing costs.

[0032] The wing reinforcement rib 1 is configured as an inwardly concave shell-like structure; when in operation, the weight of the device can be reduced while maintaining the strength of the wing reinforcement rib 1 .

[0033] The middle of the aileron reinforcement rib 2 is hollow; when working, the hollow structure can greatly reduce the overall weight of the device, which helps to improve efficiency and reduce energy consumption; in addition.

[0034] Example 2

[0035] See also Figure 4 As shown, compared with Example 1, as another implementation of the present utility model, a cross-shaped support frame 8 is fixed in the middle of the cavity of the aileron reinforcement rib 2, and the cavity of the aileron reinforcement rib 2 is filled with a lightweight filler 9; during operation, by adding the plate support frame 8 and the lightweight filler 9 to the cavity of the aileron reinforcement rib 2, the rigidity and compressive strength of the aileron reinforcement rib 2 can be increased, and the bending resistance of the aileron reinforcement rib 2 can be effectively improved.

[0036] Working principle: the aileron reinforcement rib 2, the aileron connecting plate 3, and the shaft fixing part 4 are passed through the aileron shaft 5 through the tooling. Because there is no space and mounting structure for fixing the end ribs of the aileron on the wing, the entire aileron is in a suspended state. First, the shaft fixing part 4 is used to fix the aileron reinforcement rib 2 to the aileron shaft 5 to prevent the aileron shaft 5 from moving left and right during rotation, causing the aileron shaft 5 to fall off. The aileron connecting plate 3 and the aileron shaft 5 are clearance-matched to ensure that the aileron shaft 5 can rotate. The aileron connecting plate 3 is positioned to the position of the wing reinforcement rib 1. The aileron connecting plate 3 needs to detect the web surface of the wing reinforcement rib 1 and fit with it, and then it is connected and fixed with fasteners. The overall connection structure of the device is simple, which meets the low-cost use requirements, and is convenient for installation and disassembly, thereby improving the disassembly and assembly efficiency.
