The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle shockproof undercarriage which comprises a shockproof frame, a mounting frame is slidably connected to the interior of the shockproof frame, a cross connecting frame is fixedly connected to the interior of the mounting frame, and an unmanned aerial vehicle is detachably mounted on the cross connecting frame through an adjusting mechanism. The first rack drives the driving gear and the disc to rotate clockwise, the front end of the pawl is connected with the inner ratchet wheel in a clamped mode, so that the inner ratchet wheel and the disc synchronously rotate clockwise, the inner ratchet wheel drives the second rack to slide leftwards through the first transmission gear, and the second rack drives the second rack to slide leftwards through the second transmission gear. The second rack extrudes the buffer spring, the counter-acting force generated by the buffer spring partially counteracts the upward elastic force generated by the first damping mechanism, the springback speed and strength of the first damping mechanism are weakened, the damping process is more stable and slow, the damping effect of the device is optimized, and damage to the unmanned aerial vehicle due to the high springback speed is avoided.

    本发明涉及无人机技术领域,具体涉及一种无人机防震起落架,包括防震架,所述防震架的内部滑动连接有安装框,安装框内固定连接有十字连接架,十字连接架上通过调节机构可拆卸安装有无人机,所述防震架和安装框之间对称设置有两个第一减震机构,本发明通过第一齿条带动主动齿轮和圆盘顺时针转动,棘爪的前端将和内棘轮卡接,使内棘轮和圆盘顺时针同步转动,内棘轮通过第一传动齿轮带动第二齿条向左滑动,第二齿条挤压缓冲弹簧,缓冲弹簧产生的反作用力对第一减震机构产生的向上的弹力进行部分抵消,减弱第一减震机构回弹的速度和强度,使减震过程更加平稳缓和,优化了装置的减震效果,避免了因回弹速度快对无人机造成损伤。
