In general, a vehicle is classified into a method of taking off using lift generated by a slide and a method of taking off and landing vertically by lifting the rotor from the rotation of the rotor.

A typical example of a vehicle capable of vertical takeoff and landing is a helicopter, which generates lift by rotating the vertical axis in which the rotor is installed, and advances by gaining the force in the direction of flight by tilting the plane as the rotor rotates. Has a flight mechanism

However, the helicopter is not only complicated in structure but also poor in maneuverability because the rotor is in charge of lift, thrust, and direction change. For the pitching and rolling movement and forward and backward flight, the rotor blades should be tilted by tilting the tilt plate forward, backward, left and right through cyclic pitch control, which consequently complicates the control mechanism of the main rotor system, resulting in system malfunction. In addition to being the main cause of the airframe, the fuselage is placed directly below the rotating rotor, which impedes the flow of air, resulting in poor efficiency. In particular, the flight stability drops sharply due to weather changes or the surrounding terrain.

Accordingly, there is a need for a new vertical takeoff and landing vehicle that can overcome these shortcomings. Recently, quad-rotor type (QRT) vehicles using four blades or propellers have been developed. A multi-rotor type vehicle including a vehicle is commonly referred to as a 'drone', and is a vehicle flying by using a thrust of a blade or a propeller on three or more driving sources (motors), and a rotor blade of another structure such as a helicopter and a coaxial reversal aircraft. Its structure is relatively simple compared to the aircraft, so it can be developed into a small aircraft.

However, in the case of such a conventional drone, since a plurality of rotors should be spaced apart from each other with a center around the body, there is a disadvantage in that the storage efficiency is not easy due to the large volume and thus the operation efficiency is low.

In order to solve this problem, Patent Document 1, "Foldable vertical takeoff and landing aircraft (Korean Patent No. 10-1461059)", "Upper and lower cover to form the upper and lower surfaces by providing a receiving space therein and A main body comprising a plurality of divided side covers forming side surfaces of the upper and lower covers;

Omit to avoid ambiguity

The rotor drive unit accommodating structure of the drone according to an embodiment of the present invention includes a main body 110, a rotor drive unit 130, and a folding arm 140 as shown in FIGS. 1 to 4.

First, the main body 110 will be described. As shown in FIGS. 1 to 4, the main body 110 is provided with three or more rotation shaft mounting portions 111 formed at positions symmetrical with respect to the central axis. 1 to 4 illustrate the case of a QRT (quad-rotor type, four-rotor type) vehicle which is most widely used, and the rotation shaft is installed.

In the case of the multi-rotor type air vehicle to which the rotor drive part accommodating structure of the drone of the present invention is applied, the number of the rotary shaft mounting parts 111 depends on the number of the rotor drive parts used. And accordingly the folding arm 140 is determined.

Next, the rotor driver 130 will be described. As shown in FIGS. 2 to 4, the rotor driver 130 includes three or more rotors, and typically includes a rotor in which a plurality of rotor blades 133 are installed. 132 and a rotor driving means 131 for driving the rotor 132. In this case, by individually controlling the driving of each rotor driving unit 130, the flight of the drone 100 as a whole Since the technology constituting the rotor driver 130 is a level of technology widely known and practiced in the technical field to which the present invention pertains, a detailed description thereof will be omitted.

Next, the folding arm 140 will be described. As shown in FIGS. 1 to 4, the folding arm 140 is rotated to the rotating shaft mounting unit 111 through the rotating shaft 141 formed at one end thereof. The rotor driving unit 130 is installed at each other end, and the rotor driving unit 130 is mounted at the other end, and the rotor driving unit 130 is inserted into and positioned inside the upper surface of the main body 110 in a stored state. And an upwardly inner curved portion 143 formed to be bent continuously in the direction of the central axis after bending upward in the direction.

That is, by the upwardly inner curved portion 143 formed to be bent upward in the direction of the rotor driver 130 and continuously curved in the central axis direction, the rotor driver ( 130 is inserted inside the upper surface of the main body 110, the extremely compact configuration is possible as a whole very compact configuration is possible.

In this case, at the other end of the folding arm 140, a driving means mounting unit 145 to which the rotor driving unit 130 is mounted is further formed to facilitate replacement or replacement of the rotor driving unit 130. It is desirable to be

On the other hand, during the flight of the drone 100, the collision may occur in the side due to obstacles, etc. In this case, as well as absorb the impact of the collision, it is possible to continue to have both flight capability and flight recovery capability.

Preferably, the folding arm 140 is configured to be temporarily pressed and then returned to its original position with elasticity.

In order to enable such a configuration, the folding arm 140 is moved outwardly by elastic providing means 147 provided between the rotary shaft mounting portion 111 and the rotary shaft 141 as shown in FIGS. 7 and 8. It is characterized in that it is installed to receive the elasticity, the fixing projection insertion groove 146 formed in the folding arm 140, the fixing button 112 installed on the main body 110, and the fixing button 112 It is preferably configured to further include a fixing projection 114 is inserted into the fixing projection insertion groove 146 in the stored state to secure the folding arm 140 in the stored state.

That is, when the fixing button 112 is pressed in the received state, the fixing protrusion 114 is separated from the fixing protrusion insertion groove 146, and the folding arm 140 is moved outwardly by the elastic providing means 147. When the collision occurs on the side due to obstacles or the like during the flight, the folding arm 140 temporarily has elasticity and absorbs the impact while being folded inward. Since the elasticity providing means 147 provides the elasticity in the outward direction and expands again to the use state, it is possible not only to absorb the impact caused by the collision, but also to have the ability to continue flight and flight recovery.

On the other hand, in order to switch from the use state to the storage state, simply press the folding arm 140 until the fixing protrusion 114 is inserted into the fixing protrusion insertion groove 146, the folding arm 140 ) Is fixed in the storage state

On the other hand, the rotor driving unit on the upper side of the main body 110, as shown in Figures 1 and 2 so as to be able to protect the rotor driving unit (130) and the like when carrying in a bag or bag in the storage state. Combined to cover 130

It is preferable that the cover 120 is further configured. In this case, as shown in FIGS. 1 and 2, the upper and lower curved arms 143 may respectively pass through the lower side of the cover 120. It is preferable that the passage part 121 is further formed, respectively.
