The invention discloses an unmanned aerial vehicle undercarriage structure, and relates to the field of unmanned aerial vehicles. The structure comprises a vehicle body, the outer surface of the vehicle body is provided with a group of support frames, the upper surface of each support frame is provided with a propeller, the lower part of each support frame is provided with a hinge frame, and a first damping assembly is arranged between the support frame and the hinge frame; and a lifting rod is hinged to the bottom end of each hinged frame. The design structure is reasonable, through cooperative arrangement of the wheels, the lifting rods, the sleeves, the first springs, the lifting rods, the hinge frames, the sliding blocks, the sliding boxes and the second springs, during landing, the wheels move upwards under the action of upward thrust of the ground, the sleeves can move upwards when the wheels move upwards, and movement of the sleeves can be weakened through the first springs; therefore, the damping effect of the device is improved, the supporting frame is prevented from being broken due to vibration, and the service life of the device is prolonged.

    本发明公开了一种无人机起落架结构,涉及无人机领域,包括包括机体,所述机体的外表面安装有一组支撑架,每个所述支撑架的上表面均安装有螺旋桨,每个所述支撑架的下方均设有铰接架,且支撑架和铰接架之间设置有第一减震组件,每个所述铰接架的底端均铰接有起落杆。本发明设计结构合理,它通过轮子、起落杆、套筒、第一弹簧、起落杆、铰接架、滑块、滑动箱、第二弹簧的配合设置,降落时,轮子将受到地面向上的推力向上移动,轮子向上移动能够套筒向上移动,利用第一弹簧能够对套筒的移动进行削弱,从而提高该装置的减震效果,防止支撑架因震动发生断裂,延长了该装置的使用寿命。
