The invention discloses a rotor wing structure of a triphibian unmanned aerial vehicle, which comprises an outer frame, an inner rotating frame and a paddle rotating platform, and is characterized inthat the outer frame comprises an outer contour, a lug and a lower supporting rod piece; the inner rotating frame is connected with the outer frame through balls, a rectangular partition plate is laidon the outer ring of the inner rotating frame, locking points are fixedly arranged on the upper portion of an inner ring, and an upper end net-shaped structure is connected with the inner rotating frame; a telescopic device is fixedly arranged on the lower supporting rod piece; a motor and a propeller are arranged at the end of the telescopic device. In the flight mode, the rotor wing is parallelto the horizontal position, blades rotate normally, when the triphibian unmanned aerial vehicle is switched to the sea-land form, the rotor wing is perpendicular to the horizontal position, the telescopic device pushes the blades into net-shaped structure inserting grooves to be matched, then an inner rotating ring is driven to rotate, and the walking and water treading capacity is achieved. Compared with the prior art, three functions of sea, land and air are integrated on the rotor wing, the appearance is similar to a protective cover, and the propeller is prevented from accidentally injuring people.
本发明公开一种三栖无人机的旋翼结构,包括外框架、内转架以及桨叶旋转平台,所述的外框架,包括外轮廓、凸耳与下方支撑杆件;内转架与外框架通过滚珠衔接,内转架外圈敷设矩形隔板,内圈上部固设锁点,上端网状结构与内转架连接;下方支撑杆件上固设一个伸缩装置;所述伸缩装置端部安设电机与螺旋桨。飞行模式下,旋翼平行于水平位置,桨叶正常旋转,切换到海陆形态时,旋翼垂直于水平位置,伸缩装置将桨叶推进到网状结构插槽中契合,进而带动内转圈旋转,实现行走和踩水的能力。与现有技术相比,本发明将海陆空三功能集中于一体于旋翼上,外形似保护罩,防止螺旋桨意外伤人。
