Folding-unfolding structure, rotor power assembly and tilting rotorcraft

Abstract

The present invention discloses a folding-unfolding structure, a rotor power assembly and a tilting rotorcraft. The folding-unfolding structure comprises a tilting device, a mounting table, an adapter, a driving part, a push-pull part and a plurality of lever parts. One end of the push-pull part is sildingly connected to the tilting device, the other end of the push-pull part is fixedly connected with the driving part; the adapter is connected with the driving part and the lever parts; the lever parts are used for mounting and fixing a to-be-folded part, rotatably connected to the mounting table and can rotate relative to the adapter, the tilting device drives the push-pull part to move, and thus the ends, away from the adapter, of the lever parts are driven to move upwards or downwards through the driving part and the adapter, to fold or unfold the to-be-folded part. By applying the technical scheme, the wind resistance during the flight process of unmanned aerial vehicles can be decreased, and the flight endurance is prolonged.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a folding structure, a rotor power assembly and a tilt rotor. Background technique [0002] The tiltrotor has two attitudes, the rotorcraft attitude and the fixed-wing attitude. Generally, the rotorcraft attitude is used to achieve vertical take-off and landing, while the fixed-wing attitude is used for cruising. After taking off with the rotorcraft, it is converted into a fixed-wing attitude flight Cruising can greatly extend the endurance time of the aircraft. However, when in the fixed-wing attitude, the two front power components and the blades need to continue to rotate to provide power for the fixed-wing flight and do not need to be retracted. However, after the two rear power components are tilted to the fixed-wing state, the motor stops. At this time, the airflow direction cuts the blades vertically, and the wind resistance is relatively large. In this c...

Problems solved by technology

However, after the two rear power components are tilted to the fixed-wing state, the motor stops. At this time, the airflow direction cuts the blades vertically, and the wind resistance is relatively large. In this case, more power is required to reach the predetermined flight speed, which will reduce Battery life, this situation needs to be improved
