The invention relates to an aircraft technology, in particular to a portable telescopic folding aircraft which is used for solving the problems that a rotating arm is large in occupied space, propeller blades are prone to being damaged, a protection structure for other parts of an unmanned aerial vehicle does not exist, and normal flight of the unmanned aerial vehicle is affected by increased wind resistance of the protection structure. Through the telescopic design between the rotating main arm and the rotating supporting arm, the rotating arm provided with the propeller blades can be contracted to reduce the occupied space, the propeller blades are contained in the inner side of the containing groove, the probability of collision with objects is reduced, the probability that the propeller blades are damaged is reduced, and the service life of the propeller blades is prolonged. Damage to the protection frame and the propeller blades caused by impact acting force is reduced through buffering of the traction springs on the acting force when the protection frame is impacted, and damage to the unmanned aerial vehicle caused by the acting force is reduced through buffering of the buffering springs on the acting force borne by the adjusting rod and the supporting frame. And a protection structure composed of the adjusting rod, the first electrified spring, the supporting frame and the like can contract to reduce wind resistance.

    本发明涉及飞行器技术,用于解决旋转臂占用空间大,易造成螺旋桨叶损伤,无无人机其他部件的防护结构,且防护结构增大风阻影响无人机正常飞行的问题,具体为一种便携的伸缩折叠式飞行器,本发明通过旋转主臂和旋转支臂之间的可伸缩式设计,使安装螺旋桨叶的旋转臂可收缩减小占用空间,螺旋桨叶被收纳在收纳槽内侧,减小与物体发生碰撞的可能性,使螺旋桨叶遭受损伤的可能性降低,通过牵引弹簧在防护架受到撞击时对作用力的缓冲,减小撞击作用力对防护架和螺旋桨叶造成的损伤,通过缓冲弹簧对调节杆和支撑架受到作用力的缓冲,减小作用力对无人机造成的损伤,且由调节杆、通电弹簧一和支撑架等组成的防护结构可进行收缩减小风阻。
