The invention discloses an electric telescopic mechanism of an unmanned aerial vehicle undercarriage. The electric telescopic mechanism comprises a folding arc-shaped undercarriage, a damping mechanism, driving motors, a transmission device, a pull rope set and a control system. The folding arc-shaped undercarriage is fixedly mounted at the bottom of the unmanned aerial vehicle body and comprisestwo arc-shaped foldable supporting rods and rotating shafts arranged on the supporting rods; spring reset devices are installed on one sides of the supporting rods, and when the pull rope is released,the supporting rods can be rapidly reset. The damping mechanism is fixedly installed at the end, away from the fuselage, of the folding arc-shaped undercarriage, the driving motors are fixedly installed at the edge of the fuselage of the unmanned aerial vehicle and are two gear motors, and rotating heads are arranged at the two ends respectively. The electric telescopic mechanism is simple in structure, flexible to operate and control, wide in force bearing range, safe, stable and high in reaction speed, and the undercarriage can be retracted and landed through the pull rope when the unmannedaerial vehicle takes off or quickly reset in emergency.
本发明公开了一种无人机起落架电动伸缩机构,包括:折叠弧形起落架、减震机构、驱动马达、传动装置、拉线绳组和控制系统。折叠弧形起落架,固定安装在无人机机身的底部,包括为两个弧形可折叠的支撑杆,设置在支撑杆的上的转动轴;支撑杆的一侧安装有弹簧复位装置,当拉线绳释放时可以使支撑杆快速复位。减震机构固定安装在折叠弧形起落架远离机身的一端,驱动马达固定安装在无人机机身的边缘处,为两组减速电机且两端分别设置有转动头。本发明结构精简,操控灵活,承力范围广,能够在无人机起飞时通过拉绳将起落架收回,降落或突发状况时快速复位,安全稳定,反应速度快。
