The invention provides a PLA-based 3D printing unmanned aerial vehicle wing structure and an unmanned aerial vehicle, the PLA-based 3D printing unmanned aerial vehicle wing structure comprises a plurality of independent wing boxes and carbon fiber tubes, each wing box comprises a plurality of longitudinal walls, two rib plates and skins covering the longitudinal walls and the rib plates, and the carbon fiber tubes sequentially penetrate through the wing boxes in the unfolding direction of a wing to be spliced into the wing structure. The skin and the longitudinal wall are integrally formed through 3D printing, and the rib plates are bonded with the rib plates, the skin and the longitudinal wall to form the wing structure after being manufactured through 3D printing. In order to reduce the load of the wing skin on the bending moment, a gap is formed between the adjacent wing boxes, the deformation amount of each wing box skin and the deformation displacement of the carbon fiber tube are analyzed and obtained by establishing a wing structure model, and the gap between the adjacent wing boxes is designed according to a wing deformation result. According to the design structure, on the premise that the aerodynamic performance of the wing is not influenced, the bending moment bearing of the wing skin is reduced, and the strength of the wing structure is ensured.

    本发明提供了一种基于PLA的3D打印无人机机翼结构及无人机,包括多个独立翼盒、以及碳纤维管,翼盒包括多个纵墙、两个肋板以及覆盖在纵墙和肋板上的蒙皮,碳纤维管沿机翼展向依次穿过翼盒,拼接成所述机翼结构。蒙皮与纵墙采用3D打印一体而成,肋板采用3D打印制作后,与肋板、蒙皮和纵墙粘接组成机翼结构。为减少机翼蒙皮对弯矩的承载,相邻翼盒之间设有间隙,本发明中通过建立机翼结构模型,分析获得各翼盒蒙皮的变形量及碳纤维管的变形位移,根据机翼变形结果设计相邻翼盒间隙。该设计结构在不影响机翼气动性能的前提下,减少了机翼蒙皮对弯矩的承载,确保了机翼结构的强度。
