The invention relates to the technical field of unmanned aerial vehicles, and in particular, relates to an anti-falling structure for an oblique photogrammetry unmanned aerial vehicle, wherein the anti-falling structure comprises a buffer box; a connecting hole is formed in the buffer box, a connecting bolt is inserted in the connecting hole, a spring is sleeved on the connecting bolt, an air bag groove is formed in the buffer box, and an air bag is inserted in the air bag groove. According to the technical scheme, the buffer box is in threaded connection with an aircraft body, and when an aircraft falls and touches the ground, rolling wheels are squeezed by the aircraft body and move outwards; meanwhile, an eccentric wheel is jacked upwards, and the air bag on the buffer box can be jacked out of the air bag groove to make contact with the aircraft body, so that the buffering effect can be achieved to a great extent, and the aircraft body is protected; and when the connecting bolt is extruded by the aircraft body, the connecting bolt moves downwards, so that a spring on the bolt is extruded and compressed, and the downward impact force of the aircraft body can be buffered, so that an auxiliary buffering effect is achieved, the buffering device is protected, and the service life is prolonged.
本发明涉及无人机技术领域,具体为一种倾斜摄影测量无人机用的防坠结构,包括缓冲盒,所述缓冲盒上开设有连接孔,所述连接孔中插接有连接螺栓,所述连接螺栓上套接有弹簧,所述缓冲盒上开设有气囊槽,所述气囊槽中插接有气囊,通过本技术方案的实用,缓冲盒螺纹连接在机身上,当飞机坠落触地时,滚轮受到机身的挤压,向外侧移动,同时将偏心轮往上顶,可以将缓冲盒上的气囊顶出气囊槽,与机身相接触,这样可以很大程度上起到缓冲的作用,保护了机身,且连接螺栓在受到机身的挤压时,往下运动使螺栓上的弹簧受到挤压,产生压缩,也能帮助缓冲机身向下的冲击力,从而起到辅助缓冲的作用,且也使缓冲装置受到了保护,增加了使用寿命。
