[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figs. 1-7, the multi-functional landing gear of many rotor wing unmanned aerial vehicles, has landing gear and protective guard two kinds of functions concurrently. Described many rotor wing unmanned aerial vehicles are have two rotors and above without man-machine. Described multi-functional landing gear comprises umbrella shape protective guard 10, landing gear body 9, anchor 6, drag spring 7, running block 5, connecting rod 4, increases steady card 3, power motor 12.
Described anchor 6 is fixed on below unmanned wing bar 1, landing gear body 9 rear end and anchor 6 are hinged, umbrella shape protective guard 10 is installed on landing gear body 9 front end, landing gear body 9 rear end is connected with wing bar 1 through drag spring 7, connecting rod 4 is connected to form by two quarter butt movable axis, wing bar 1 time end is fixed in connecting rod 4 one end, the other end is fixed on the rotation axis bottom of landing gear body 9 rear end, power motor 12 is arranged in the middle part of unmanned aerial vehicle body, wing bar 1 is provided with running block 5, traction rope 11 is walked around running block 5 one end and is connected with the movable axis of connecting rod, the other end is connected with power motor 12. landing gear body is in vertical position when landing, and can outwards lift when flying.
Further, having rotation axis 8 in described anchor 6, described landing gear body 9 is arranged on rotation axis 8, and landing gear body 9 can flexible rotating.
Further, described wing bar 1 front end is provided with and increases steady card 3, lifts to blocking in increasing surely blocks during vertex at landing gear body 9, prevents from rocking. Increasing steady card 3 is rectangular block, and bottom has oblique deep-slotted chip breaker, and landing gear can be wrapped in wherein after lifting.
