The invention belongs to the technical field of aviation, particularly relates to the technical field of unmanned aerial vehicle wing rotation, and particularly relates to a folding wing unfolding rotating shaft mechanism. The folding wing unfolding rotating shaft mechanism comprises wings and a connecting base fixed to an unmanned aerial vehicle, and two connecting bosses are fixedly arranged onthe connecting base. The two connecting bosses are rotationally connected with the wing root of one wing separately. A sliding rail is fixedly arranged in the connecting base between the connecting bosses. Driving force is provided through a gunpowder actuator cylinder, a rack is pushed to move, a first gear and a second gear are driven to rotate synchronously, and the left wing and the right wingrotate at the same time to be unfolded quickly. The left wing and the right wing adopt independent rotating shafts, and compared with a coaxial unfolding mechanism, the connecting mode is simple, andreliable wing root connection is easily ensured. Compared with multi-connecting-rod force transmission, the transmission of the folding wing unfolding rotating shaft mechanism is achieved in a gear and rack meshing mode, so that the structure is compact, and rotation is more stable.
本发明一种折叠机翼展开转轴机构涉及本发明属于航空技术领域,特别是无人机机翼转动技术领域,具体涉及一种折叠机翼展开转轴机构,包括机翼及固定在无人机上的连接底座,所述连接底座上固定设置有两个连接凸台,两个连接凸台分别与一个机翼的翼根转动相连;所述连接凸台之间的连接底座上固定设置有一滑轨;本发明通过火药作动筒提供驱动力,推动齿条移动,带动第一齿轮和第二齿轮同步转动,实现左右机翼同时旋转转开,以实现机翼迅速展开。左右机翼采用独立的旋转轴,相比于共轴展开机构,连接方式简单,易确保了机翼根部连接可靠。通过齿轮齿条啮合方式传动,相比于多连杆传力,结构紧凑,转动更平稳。
