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

Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0038] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

Abstract

The invention discloses a folding structure, a rotor power assembly and a tilt rotor, wherein the folding structure includes a first motor, a mounting platform, a connecting piece, a driving piece and a plurality of lever pieces; The mounting platform is provided with the plurality of levers; the first motor includes a rotating shaft, and the rotating shaft of the first motor is threadedly engaged with the driving member, the driving member is connected to the adapter, and the rotating shaft The connecting piece is rotatably connected with the plurality of lever pieces. The technical scheme of the invention can reduce the wind resistance encountered by the drone during flight, and prolong the flight endurance time.

Description

Technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a folding and retracting structure, a rotor power assembly and a tilt rotor aircraft. Background technique [0002] The tilt-rotor aircraft has two attitudes, namely 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 cruise, and the rotorcraft is used to convert to a fixed-wing attitude after takeoff. Cruising can greatly extend the life of the aircraft. However, in the fixed-wing attitude, the front two power components, the blades need to continue to rotate to provide power for the fixed-wing flight, and do not need to be folded. 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 blade vertically, and the wind resistance is large. In this case, more power is...
