Title:
UNMANNED AERIAL VEHICLE PROVIDED WITH RETRACTABLE AND EXTENSIBLE UNDERCARRIAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/090942
Kind Code:
A1
Abstract:
An unmanned aerial vehicle provided with a retractable and extensible undercarriage device comprises a fuselage (200), a photographing device (300), a flight state detection device, an undercarriage (400), an undercarriage driving mechanism, and a control unit (250). By means of the flight state detection device, conditions about takeoff, landing and other flight states are correctly recognized, and accordingly the unmanned aerial vehicle is automatically controlled to automatically retract and extend the undercarriage (400). When the unmanned aerial vehicle leaves the land and takes off, the undercarriage (400) gradually moves to a position outside the photographing range of a lens module (320) according to a state in which the unmanned aerial vehicle is in a liftoff state, so that the undercarriage (400) is prevented from shading the visual field of the photographing device (300), thereby improving an effective photographing range, and avoiding limitation of a photographing visual angle.
