The invention discloses a reconfigurable multi-rotor unmanned aerial vehicle based on bistable hinges. The reconfigurable multi-rotor unmanned aerial vehicle comprises the bistable hinges, rotor assemblies, magnets, grippers and the like. The bistable hinge is composed of a machine body module, a pin shaft and a tension spring. The unmanned aerial vehicle has two different fuselage configurations of an annular (configuration A) and a linear (configuration B), magnet attraction and spring tension are overcome through reaction torque generated by clockwise/anticlockwise rotation of the rotor wings in the same direction, the fuselage hinge steady state is switched, opening/closing of the unmanned aerial vehicle fuselage is achieved, and the wheelbase of the unmanned aerial vehicle is changed while the fuselage configuration of the unmanned aerial vehicle is switched. Moreover, under the two fuselage configurations, the structural stability of the unmanned aerial vehicle is jointly ensured by the tension of the tension springs and the attraction of the magnets. In addition, due to the linear fuselage structure and the hollow annular fuselage structure, the unmanned aerial vehicle has the capacity of shuttling back and forth in a narrow space and grabbing objects.

    本发明公开了一种基于双稳态铰链的可重构多旋翼无人机,包括双稳态铰链、旋翼组件、磁铁和手抓等。其中双稳态铰链由机身模块、销轴与拉力弹簧组成。该无人机具备环形(构型A)与“一”字形(构型B)两种不同的机身构型,通过旋翼同向顺/逆时针旋转产生的反扭矩克服磁铁吸力和弹簧拉力,切换机身铰链稳态,实现无人机机身的“开”/“合”,在转换无人机机身构型的同时改变无人机轴距。并且,在两种机身构型下,拉力弹簧的拉力与磁铁的吸引力共同保证了无人机的结构稳定性。此外,“一”字形机身构型与中空的环形机身构型分别使该无人机具备了穿梭狭窄空间和抓取物体的能力。
