The present invention relates to an unmanned aerial vehicle (UAV), and more particularly, to a propeller that generates a lift force, a torque can be distributed and supplied to a propeller by a single motor, And more particularly, to a UAV that distributes power from a single motor that can be easily modified to suit the intended use of the aircraft.

The most popular unmanned aircraft in recent years is made up of multiple shafts and consists of a number of propellers and a number of motors that can rotate them. It has evolved into many forms as those required for stable balance and rapid rotation of the aircraft. In recent years, there has been a tendency to develop luggage on unmanned aerial vehicles and aircraft capable of carrying people directly, and the size is also becoming larger. However, it is very difficult to obtain the lift required when the air is blown up due to the weight of the propeller and the revolving motor which are made up of multiple axes, and the number of propellers and revolving motors is large. Since the increase in the quantity is essential, there have been many difficulties in making the aircraft due to the weight of the motor.

In order to solve the above-mentioned problems, the present invention uses a single shaft of a power source and a flexible shaft that transmits a rotational force to distribute and supply a stronger rotational force than a combination of motors required for a plurality of propellers, So that the unmanned airplane can float in the air.

According to an aspect of the present invention, there is provided an unmanned aerial vehicle including a plurality of unmanned aerial vehicles for distributing power in a single motor of the present invention,

A sphere provided with a single motor that fixes the plurality of blades at a predetermined interval and provides a rotating force to the flexible shaft so that the propeller can be rotated and floated in the air,

And at least one pair of legs capable of lifting the sphere at a predetermined height from the floor so as to take off and land the fixed sphere.

Further, the blades may include a propeller capable of rotating and obtaining lift, an upper bevel gear and a lower bevel gear integrally coupled to upper and lower portions so as to transmit rotational force to the propeller, and a plurality of A reverse bevel gear which is located at a predetermined interval and is engaged and balanced to balance the rotation of the upper bevel gear and the lower bevel gear, A wing support frame integrally formed with the wing support frame so as to be fitted to a fixing frame of the wing and to protect the flexible shaft; The reverse bevel gear and the connecting bevel gear, which are located between the gear and the lower bevel gear, And a connecting bolt and the connecting nut for fastening to be well in engagement,

And a flexible shaft inserted into the wing support rod and capable of transmitting the rotational force supplied from the single motor to the connecting bevel gear.

The sphere may include a single motor capable of supplying a rotational force to a plurality of blades without a rotary motor, a lower bevel gear coupled to an upper surface of the single motor to transmit rotational force to the upper bevel gear and the connecting bevel gear, A plurality of connecting bevel gears which are positioned between the bevel gear and the lower bevel gear and rotate in the reverse direction at a high speed when the lower bevel gear rotates; And an upper bevel gear meshed with the upper bevel gear.

The sphere may include a base plate having a circular hole at the center and having a predetermined thickness so that a lower portion of a single motor can be inserted and fixed, and a fixing frame capable of fixing the plurality of wing support rods A connecting plate including a support for allowing the bevel gear to rotate smoothly; an upper plate having a fixing groove including a bearing therein so as to firmly fix the upper bevel gear in a central axis direction; And connecting bolts (21a, 22a, 23a) for tightly fastening between the connecting plate and the upper plate to complete the sphere.

The unmanned airplane that distributes the power in a single motor according to the present invention maximizes the rotational force by integrating the number of revolving motors for rotating the propeller into a single motor. It is possible to secure a strong torque due to the increase of the motor size The size of the propeller can be increased, and the load can be increased, resulting in heavy load.

In addition, even if the length of the wing support rod is freely deformed, the rotational force supplied from the central single motor can be uniformly transmitted to the flexible shaft, so that the number of wings can be adjusted and changed according to the purpose of the aircraft, It is possible to load more effectively and to operate more effectively.
