The unmanned aerial vehicle undercarriage comprises a vehicle body, an outer skirt frame is fixedly connected to the outer side of the bottom end of the vehicle body, a plurality of connecting holes are formed in the periphery of the top end of the outer skirt frame, vehicle arms are arranged in the connecting holes, and one ends of the vehicle arms are located at the circle centers of the connecting holes. Through the arrangement of the adjustable undercarriage, a transmission bevel gear is driven by a main bevel gear to drive a driving rod to rotate, meanwhile, a sliding block is driven by the driving rod to slide towards the opposite side or the opposite direction, and the bottom ends of supporting strips following the sliding block are opened and closed outwards or close to each other; at the moment, the supporting guide wheels installed at the bottom ends of the supporting strips roll towards the two sides or the opposite sides, so that the height of the gravity center of the unmanned aerial vehicle is adjusted according to the self weight of the unmanned aerial vehicle or the take-off and landing environment, stability of the unmanned aerial vehicle is guaranteed, and losses caused by falling of the unmanned aerial vehicle due to collision caused by too high gravity center are prevented.

    本发明公开了一种无人机起落架和无人机,涉及无人机技术领域,包括机体,所述机体底端外侧固定连接有外裙架,所述外裙架的顶端四周皆开设有数个连接孔,且连接孔的内部皆设置有机臂,所述机臂一端位于连接孔的圆心处。本发明通过设置的可调节起落架,通过传动锥齿轮受到主锥齿轮传动使其带动驱动杆进行旋转,同时滑块受到驱动杆的传动使其向相对侧或者相反方向滑动,其跟随的支撑条底端向外开合或者相互靠近,此时安装于支撑条底端的支撑导轮向两侧滚动或者向相对侧滚动,从而有利于根据无人机自重或者起降环境,以此来调整无人机重心的高低,保证无人机稳定,防止重心过高发生碰撞,导致无人机发生倾倒造成损失。
