The invention discloses an undercarriage of a vertical take-off and landing unmanned aerial vehicle. The device comprises a connecting frame, a triangular lug plate on the lower side of the connectingframe is rotationally connected with an angular connecting plate; first spring positioning grooves are symmetrically formed in the lower side, close to the two ends, of the connecting frame. Second spring positioning grooves are symmetrically formed in the upper side, close to the two ends, of the angular connecting plate. A compression spring is limited between the first spring positioning groove and the second spring positioning groove, a through hole penetrating through the connecting plate is formed in the first spring positioning groove, a preload adjusting column is connected into the through hole in a threaded mode, supports are symmetrically fixed to the two ends of the angular connecting plate, horizontal rod parts are arranged at the outer ends of the supports, and multifunctional contact pins are rotationally supported on the outer sides of the horizontal rod parts. The multifunctional contact pin is arranged at the outer end of the support and comprises four contact faces,switching of the bottommost contact face, namely the actual contact face, can be achieved through the micro servo motor, adjustment of the rigidity of the compression spring can be achieved by rotating the preloading adjusting column, and stability during stopping is guaranteed.

    本发明公开了一种垂直起降无人机起落架,包括连接架,连接架的下侧三角耳板转动连接有角形连接板,且连接架的下侧靠近两端对称设有第一弹簧定位槽,角形连接板的上侧靠近两端对称设有第二弹簧定位槽,第一、第二弹簧定位槽之间限制有压缩弹簧,第一弹簧定位槽中开设有贯穿连接板的穿孔,且穿孔中螺接有预载调节柱,角形连接板的两端对称固定有支架,支架的外端设有水平杆部,且水平杆部的外侧转动支撑有多功能接触脚。本发明在支架的外端设置多功能接触脚,多功能接触脚包含四个接触面,利用微型伺服电机可实现最底侧接触面即实际接触面的切换,通过旋转预载调节柱能够实现压缩弹簧刚度的调节,保障停落时的稳定性。
