The invention provides a high-speed unmanned aerial vehicle empennage deflection mechanism. An empennage deflection assembly comprises a fixing plate, a motor, a lead screw, a nut, a connecting rod, a crank, a rotating shaft and a fixing part. The number of the motors is at least one, the motors are fixed on the fixing plate, each motor is connected with one lead screw, each lead screw is provided with one nut, and the motors drive the lead screws to rotate and drive the nuts to move linearly; two ends of the connecting rod are respectively hinged with a nut and a crank; the two fixing parts are fixed to the fixing plate, the two ends of the rotating shaft extend into the fixing parts respectively to form shaft hole fit, and the crank is fixedly connected with the rotating shaft and the empennage. The empennage deflection assembly is arranged below the wings of the unmanned aerial vehicle. The device has the functions of force increasing and stroke amplifying, the rigidity of the deflection assembly is improved, and the requirements for high-bearing variable configuration and large rigidity of high-speed unmanned aerial vehicle folding empennage deflection can be met.

    本发明提供了一种高速无人机尾翼偏转机构,包含的尾翼偏转组件包括固定板、电机、丝杠、丝母、连杆、曲柄、回转轴、固定部;电机至少有一个,固定在固定板上,每个电机连接一根丝杠,每根丝杠上装配一个丝母,电机带动丝杠转动、驱动丝母直线位移;连杆两端分别与一个丝母、一个曲柄铰接;两个固定部固定在固定板上,回转轴两端分别伸入一个固定部、形成轴孔配合,曲柄与回转轴、尾翼固定连接;尾翼偏转组件设置在无人机机翼下方。本发明具有增力及行程放大功能,提高偏转组件刚度,能够满足高速无人机折叠尾翼偏转要求的高承载变构型、大刚度要求。
