The manta ray imitating aircraft pectoral fin assembly device comprises a fin plate body and a connecting assembly, the fin plate body is in a triangular plate shape, the fin plate body comprises a rigid connecting side edge and a rigid front edge which are integrally connected, and the structure can generate fluctuation of the plate surface in the wing flapping process to improve the propelling effect; a first connecting shaft hole and a second connecting shaft hole which are perpendicular to each other are formed in a right-angle adapter of the connecting assembly and connected with the output shaft and the fin plate body respectively, a protruding limiting structure is arranged on the side edge shaft face of the rotating shaft, and a limiting groove matched with the protruding limiting structure is formed in the inner side edge face of the second connecting shaft hole. The convex limiting structure and the limiting groove are in concave-convex limiting fit at a preset interval, and the rotating angle of the rotating shaft in the second connecting shaft hole is limited within a preset angle range; and an elastic mechanism is connected between the right-angle adapter and the fin plate, and the structure is matched with a fin plate structure so that fluctuation can be generated during working to optimize propulsion.
本发明提供了一种仿蝠鲼航行器胸鳍总成装置,包括鳍板主体以及连接组件,鳍板主体呈类三角形板状,鳍板主体包括一体连接的刚性连接侧缘、刚性前缘,该结构能够在扑翼的过程中产生板面的波动提高推进效果;连接组件的直角转接件设置有相互垂直的第一连轴孔和第二连轴孔,分别与输出轴和鳍板主体连接,旋转轴的侧缘轴面设置有凸起限位结构,第二连轴孔的内侧缘面设置有与凸起限位结构配合的限位槽,凸起限位结构与限位槽之间保持预设间距的凹凸限位配合,将旋转轴在第二连轴孔内的旋转角度限定在预设角度范围内;直角转接件与鳍板之间连接有弹性机构,该结构配合鳍板结构能够在工作时产生波动优化推进。
