Description

Technical Field

[0001] This invention relates to a mold structure for a connector between the transition section and the upper inverted section of a UAV wing. Specifically, it relates to a mold structure for preparing a carbon fiber composite connector between the transition section and the upper inverted section of a UAV wing. More particularly, it relates to a wing connector mold structure and a method for manufacturing the wing connector. Background Technology

[0002] In the development and manufacturing of UAVs, the connecting component between the wing transition section and the dihedral section serves to connect them according to design requirements, creating an angle between them. To improve connection strength and precision, and to ensure airfoil accuracy and stability so as to control the UAV's pitch angle within the allowable error range, high requirements are placed on the strength, rigidity, and precision of the connecting component.

[0003] The manufacturing cost of connectors depends on the manufacturing method, which in turn affects the manufacturing time and the quality of the finished product. In the manufacturing process of carbon fiber composite connectors, while traditional composite laminates offer excellent mechanical properties, the addition of multiple layers of carbon cloth significantly increases the weight of the finished product, raising manufacturing costs and complicating subsequent processing. Therefore, focusing on the lightweight and high-strength technical requirements of UAVs, the application of foam-core carbon fiber composite connectors is beneficial for reducing the weight of finished components, improving manufacturing accuracy, and lowering manufacturing costs. However, structurally, carbon fiber-coated foam-core connectors are very difficult to mold in one piece due to their complex structure, complex parting lines, porous nature, and the need for side core pulling. Therefore, the design of the connector mold structure, assembly, and demolding is crucial.

[0004] In terms of quality, the manufacturing precision of the connector between the transition section and the inverted section, a crucial component of the drone's wing, directly affects the drone's aerodynamic characteristics. Therefore, a reasonable connector mold design is essential to ensure the connector is lightweight, high-strength, and high-precision. However, there are currently few reports on the design of drone wing connector molds. Summary of the Invention
