The invention discloses a connecting rod folding portable four-rotor unmanned aerial vehicle with a protection mechanism, and relates to the technical field of unmanned aerial vehicles. The problems that on one hand, propellers of an existing rotor wing folding type unmanned aerial vehicle are not protected; on the other hand, when a protection structure is additionally arranged on the propeller, if the propeller is collided by an obstacle, external force borne by the propeller can be transferred to the folding rotor wings, the folding rotor wings are in a soft limiting mode, when the force borne by the collision exceeds a certain degree, faults can happen, and the falling phenomenon can be caused seriously. The unmanned aerial vehicle with the structure is high in folding efficiency; on the other hand, the four rotors are designed into two layers respectively, and the four rotors can be located at the same height through one pressing and stacking action; and the magnetic rings are arranged on the outer surfaces of the guide limiting pieces, so that the four protection covers are connected with one another to form a force closed ring, the wing blades are better protected, the bearing capacity of the protection covers can be further improved through the design, and the fault or falling phenomenon is avoided. The invention is applicable to the technical field of unmanned aerial vehicles.
一种带保护机构的连杆折叠便携式四旋翼无人机,涉及无人机技术领域。为解决现有旋翼折叠式无人机一方面没有对其螺旋桨进行保护;另一方面对螺旋桨加上保护结构时,如果受到障碍物的碰撞所受的外力会转移到折叠旋翼上,折叠旋翼为软限位方式当碰撞所受的力超过一定程度时会发生故障,严重时会导致跌落现象的问题。此种结构的无人机折叠效率高;另一方面将四旋翼分别设计成两层,进行一压叠动作即可实现四旋翼处于同一高度;并且再结合导向限位件的外表面上设有磁环,让四个保护罩相互连接形成力闭环,从而对机翼叶片起到更好的保护作用,并且这样设计可以进一步提升保护罩的承受能力,避免发生故障或跌落的现象发生。本发明适用于无人机技术领域。
