The invention provides a bionic butterfly aircraft. The bionic butterfly aircraft comprises a rack, a pair of wings, a driving device, a steering engine, a bevel gear transmission device, a six-connecting-rod-universal-joint steering device and a hose. The six-connecting-rod-universal-joint steering mechanism is located on the front side of the whole rack, and universal joints are embedded in the rack, are distributed in a symmetrical mirror image mode in the stable and normal flight process and are fixed and controlled through sleeves distributed on the two sides of the rack. The six connecting rods are connected with the sleeves and the steering engines located on the front side of the rack through the connecting shafts, the steering engines on the front side drive the connecting rods to rotate, torque is transmitted to the universal joints through the sleeves, so that the wings are controlled to yaw, the universal joints ensure that flapping frequencies at the two ends are consistent in the yaw generation process, and stable steering in the flight process is achieved. The helical gear transmission mechanism is composed of six helical gears, the torque of the steering engine is transmitted through mutual meshing of the helical gears, the transmission space is reduced through the ingenious helical gear design, and the helical gear transmission mechanism can turn in a smaller turning radius. It is worthy that the wings are divided into the front wings and the rear wings through the hoses, in the flight process, the front wings drive the rear wings to better simulate flight of the butterfly, and therefore the performance of the whole system is improved. The bionic butterfly aircraft has a unique and ingenious steering mechanism, maneuvering and stability in a low-energy-consumption state are achieved, cost is low, and innovativeness is achieved.

    本发明提供了一种仿生蝴蝶飞行器,其包括机架,一对机翼,驱动装置,舵机,斜齿轮传动装置,六连杆‑万向节转向装置,软管。该六连杆‑万向节转向机制,位于整个机架的前侧,万向节嵌在机架之内,在平稳正常飞行过程中呈对称镜像分布,由分布在机架两侧的套筒将其固定并控制。所述六连杆通过连接轴与套筒和位于机架前侧的舵机相连,前侧舵机带动连杆旋转,将转矩通过套筒传递至万向节,从而控制机翼产生偏航,所述万向节在产生偏航的过程中保证了两端扑翅频率一致,实现飞行过程中的平稳转向。所述斜齿轮传动机制,由六个斜齿轮组成,通过斜齿轮之间的相互啮合,传递舵机力矩,巧妙的斜齿轮设计减小了传动空间,使其能在更小的转弯半径内转弯。值得提及的是,本发明通过软管将翅膀分为前翅与后翅,在飞行过程中,通过前翅带动后翅可更好地模拟蝴蝶的飞行,从而提高整个系统性能。该仿生蝴蝶飞行器,拥有独特巧妙的转向机制,实现了低耗能状态下的机动与稳定,成本低,具有创新性。
