The invention discloses a retractable unmanned aerial vehicle convenient to fly in dangerous terrains, and belongs to the field of unmanned aerial vehicles. According to the scheme, when the unmanned aerial vehicle flies in the dangerous terrains, if the unmanned aerial vehicle encounters the terrains with narrow space, an infrared sensing system firstly performs infrared scanning on the terrains and performs data analysis on the distance; then the size of the unmanned aerial vehicle is compared with the size of the unmanned aerial vehicle, when it is detected that the fuselage of the unmanned aerial vehicle is larger than the front flight space, the infrared sensing system sends information to the contraction control system, and the contraction control system controls the electrically-controlled propeller frame and the supporting frame to start to contract through signal connection; the size of the contracted unmanned aerial vehicle can enable the unmanned aerial vehicle to pass through the narrow space at the moment, and in the contraction process of the electric control propeller frame, a limiting bag sleeve in the electric control propeller frame is slowly embedded into a limiting groove through a through hole under the action of extrusion force to complete fixation of contraction of the electric control propeller frame; therefore, the unmanned aerial vehicle can still fly and cross in narrow space of dangerous terrains.

    本发明公开了一种便于险恶地形飞行的可收缩型无人机,属于无人机领域,本方案可以实现当无人机在险恶地形进行飞行时,如遇到空间狭小的地形后,其红外线感应系统首先对地形进行红外扫描,对其距离进行数据分析,随后与自身尺寸进行比对,当检测出无人机机身大于前方的飞行空间时,红外线感应系统向收缩控制系统发出信息,而收缩控制系统通过信号连接进行控制电控螺旋桨架和支撑架开始收缩,使收缩后的尺寸能使无人机通过此时的狭隘空间,而电控螺旋桨架在收缩的过程中,其内部的限位囊套在挤压力的作用下透过通孔慢慢嵌入进限位槽内完成对电控螺旋桨架收缩的固定,从而致使无人机能够在险恶地形狭隘空间下仍能飞行穿越。
