Air-ground amphibious mini unmanned aerial vehicle

Abstract

The invention provides an air-ground amphibious mini unmanned aerial vehicle which comprises a rack, an upper rotor wing component, four lower rotor wing components and a connecting rod. The upper rotor wing component comprises an upper paddle and an upper motor arranged on the rack, the upper paddle is connected with a rotating shaft of the upper motor, and the upper end of the connecting rod is rotatably connected with the rack through an upper steering motor with a self-locking function; center connecting lines of the two lower rotor wing components which are arranged oppositely are perpendicular to each other, each lower rotor wing component comprises a base, an annular hub, a plurality of rollers, a lower paddle and a lower motor, each base is rotatably connected with the lower end of the connecting rod through a lower steering motor with a self-locking function, the center of each annular hub is connected with a base bearing, the rollers are arranged along the periphery of the corresponding annular hub and rotate around a rotating shaft in the tangential direction of the corresponding annular hub, each lower motor is arranged on the corresponding base, and each lower paddle is connected with a rotating shaft of the corresponding lower motor. Lower rotor wings of the unmanned aerial vehicle can realize air-ground amphibious switching by swinging the connecting rod.

Description

technical field

[0001] The invention relates to an unmanned aerial vehicle technology, and Terne is a ground-air amphibious miniature unmanned aerial vehicle. Background technique

[0002] Traditional large-scale UAVs mainly use four-rotor, six-rotor or multi-rotor to perform tasks such as shooting, monitoring and reconnaissance in the near-ground environment. However, due to reasons such as complex structure and difficult manipulation, the development of large-scale quadrotor UAVs has been relatively slow. . In recent years, with the advancement of new materials, micro-electro-mechanical (MEMS), micro-inertial navigation (MIMU) and flight control technologies, micro-UAVs have developed rapidly and have gradually become the focus of attention.

[0003] Micro drones are especially suitable for monitoring, reconnaissance and other tasks in near-ground environments (such as indoors, urban areas and jungles, etc.), and have broad military and civilian prospects; at the same tim...
