Abstract

The invention discloses a single-layer variable-distance coaxial structure applied to an unmanned aerial vehicle, and belongs to the technical field of the unmanned aerial vehicles. The structure comprises an actuating unit, a coaxial mechanism and a driving mechanism, wherein the coaxial mechanism comprises an upper rotary sleeve, a lower rotary sleeve and a hollow shaft, and the upper rotary sleeve, a hollow slot and the lower rotary sleeve are sequentially arranged on the hollow shaft in a sleeving manner; the actuating unit can respectively drive the upper rotary sleeve and the lower rotary sleeve to rotate while rotating around the hollow shaft; the driving mechanism is arranged on the bottom end of the hollow shaft in a sleeving manner; therefore, the distance change operation of a rotor wing can be achieved only through driving one rotary sleeve to rotate relative to the other rotary sleeve by the driving mechanism; the distance change operation is simplified via a single-layervariable-distance design; the whole structure is simple, easy to maintain and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, in particular to a single-layer variable distance coaxial structure for unmanned aerial vehicles. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft can track, locate, remote control, telemetry and digital transmission of the UAV through radar and other equipment. The UAV can take off like an ordinary aircraft under radio control or be launched into the air with a booster rocket, or it can be brought into the air by the parent aircraft for flight. When recovering, the UAV can automatically land in the same way as an ordinary aircraft landing process, or it can be recovered with a parachut...
