The invention belongs to the technical field of unmanned aerial vehicles, in particular to a six-wing unmanned aerial vehicle capable of achieving multi-azimuth landing emergency stop. The invention provides the following scheme to solve the problems that an existing unmanned aerial vehicle is long in landing time when landing, and easily collides with other objects on a landing surface and damages parts of the unmanned aerial vehicle when sliding on some small-area landing surfaces for a long time. The six-wing unmanned aerial vehicle capable of achieving multi-azimuth landing emergency stopcomprises an annular fixed frame which sleeves the outer side of an unmanned aerial vehicle body, wherein a plurality of support columns are fixedly connected between the annular fixed frame and the side end of the unmanned aerial vehicle body; buffer legs are fixedly connected to the lower ends of the support columns; roller wheels are connected to the lower ends of the buffer legs; power mechanisms are fixedly connected to the buffer legs; and a direction sensor is connected to the lower end of the unmanned aerial vehicle body. After the unmanned aerial vehicle touches the ground, a plurality of micro servo motors drive the roller wheels to roll in different directions according to a slide direction, detected by the direction sensor, of the unmanned aerial vehicle, so that the unmanned aerial vehicle is subjected to force opposite to the original slide direction, thus realizing emergency stop of the unmanned aerial vehicle.
本发明属于无人机技术领域,尤其是一种多方位落地急停六翼无人机,针对现有的无人机在落地时停落时间长,而在一些面积较小的停落面上,滑行过长则容易与停落面上的其他物体发生碰撞,损坏无人机零件的问题,现提出以下方案,包括在无人机机身外侧套设有环形固定架,环形固定架与无人机机身侧端之间固定连接有多个支撑柱,支撑柱下端固定连接缓冲腿,且缓冲腿下端连接有滚轮,缓冲腿上固定连接有动力机构,无人机机身下端连接有有方向传感器。本发明可在无人机触地后,根据方向传感器检测到无人机的滑动方向使得多个微型伺服电机驱动滚轮进行不同方向上的滚动,从而使得无人机增大其受到与原滑动方向相反的力,从而实现无人机的急停。
