The invention relates to the technical field of obstacle avoidance for unmanned aerial vehicles, and discloses an obstacle avoidance device for an unmanned aerial vehicle and an obstacle avoidance method thereof.The obstacle avoidance device comprises an unmanned aerial vehicle body, and a plurality of unmanned aerial vehicle cantilevers are fixedly connected to the side wall of the unmanned aerial vehicle body. By arranging the linkage mechanism, when the unmanned aerial vehicle climbs, the top of the unmanned aerial vehicle collides with an obstacle, an anti-collision frame in the linkage mechanism firstly makes contact with the obstacle, the anti-collision frame is extruded by the obstacle to drive a sliding pipe to slide downwards along a protection rod, and the sliding pipe drives a limiting block to extrude a compression spring along the protection rod; the limiting block drives the sliding block at one end of the first linkage rod to slide inwards along the sliding groove frame, the sliding block drives the friction block at one end of the second linkage rod to move upwards along the rotating shaft, and when the friction block and the extrusion friction sleeve extrude each other, friction is generated between the friction block and the extrusion friction sleeve, so that the rotating speed of the rotating shaft on the extrusion friction sleeve is reduced.
本发明涉及用于无人机的避障技术领域,且公开了一种用于无人机的避障装置及其避障方法,包括无人机主体,无人机主体的侧壁固定连接有若干个无人机悬臂。本发明通过设置联动机构,当无人机爬高时,无人机的顶部碰撞到障碍,联动机构中的防撞架首先接触到障碍,防撞架受到障碍的挤压带动滑动管沿着防护杆向下滑动,滑动管带动限位块沿着防护杆挤压压缩弹簧,限位块带动联动杆一一端的滑动块沿着滑槽架向内部滑动,滑动块带动联动杆二一端的摩擦块向上沿着旋转轴移动,当摩擦块与挤压摩擦套相挤压时,摩擦块与挤压摩擦套产生摩擦,这样设置有利于挤压摩擦套上的旋转轴的转速降低。
