Description
The present invention relates to an arm coupling device for an unmanned airplane, and more particularly, to an arm coupling device for an unmanned airplane, in which a plurality of arms are provided on four sides of a base, To an arm coupling device of an unmanned airplane capable of reducing storage and transportation volume by allowing motors and wings to be separated from and stored in a gas.
In recent years, the need for unmanned aerial vehicles is increasing in environments where people can not work. Unmanned aerial vehicles (UAVs) are increasingly required to provide information on enemy cloaking in aerial image acquisition, aerial photographing, powerline inspection or battlefield situations in disaster / disaster areas, or to carry out reconnaissance missions and surveillance missions through unmanned aerial vehicles .
A conventional unmanned airplane has been disclosed in Japanese Patent No. 1366208. This allows the user to conveniently move, assemble, and disassemble the air vehicle, and the first and second fixing members formed on the lower fixing member can be used for the landing gear unit And the landing gear is firmly fixed to the lower fixing part, thereby preventing further shaking or distortion when the airplane is in flight.
Domestic patent No. 1042200 is also a unmanned airplane, which reduces the weight of the arm connecting the airframe and the rotor to reduce the weight of the aircraft. However, these conventional patents are disadvantageous in that they occupy a large storage volume when the unmanned airplane is not used, because the rotor arm is installed in the unfolded state. Also, when the unmanned airplane is transported, it requires a lot of space for loading in the vehicle, so that the number of passengers is limited.
The inventor of the present invention has registered the unmanned airplane with the patent No. 1456035 in view of this. The arm fixing member is provided between the upper and lower plates of the base so as to reduce the storage width of the arms extended to the four sides of the base. The arm connecting member is provided on the rotor arm. The arm connecting member and the arm fixing member are provided with means for transferring lifting force generated when the wing is rotated to the gas through the rotor arm.
However, the registered patent of the present inventor has a problem that since the arm is folded to the lower part of the gas, the height is rather increased, so that the storage volume can not be reduced significantly, and in particular, it is troublesome when the driver directly moves the gas and moves the long distance.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide an air conditioner which has a plurality of arms in four directions of a gas and has wings rotated by motors at the ends of the arms, The motor and the wings are separated from and stored in the gas, the storage volume can be reduced, and the fixing body for coupling the arm to the gas can be separated and formed symmetrically with each other, And a lever for holding the arm between them is pivoted so as to be rotatable, thereby facilitating assembly of the arm coupling device of the unmanned airplane.
To this end, the present invention provides an arm coupling device for an unmanned airplane in which a plurality of arms having wings rotated by a motor are provided at free ends, and fixed ends of the arms are fitted to the four sides of the base, Wherein the fixing body is formed with an insertion hole into which the fixed end of the arm is inserted; A pair of levers are rotatably provided on both sides of the fixed body, and a part of each of the levers is protruded from the fitting hole so as to be engaged with an engaging groove formed on both sides of the fixed end of the arm, And to be coupled to the body.
According to the present invention, since the arm connecting the gas and the motor is completely separated from the gas, the volume of the unmanned airplane can be reduced. It is also possible to mount motors with different outputs on a single body, the length of the arms varying in proportion to the output of the motor and the number of revolutions of the wing. That is, when assembling a small output unmanned airplane, a short arm can be used compared to a large output unmanned airplane.
In the present invention, the fixing body is provided as means for fixing the arm to the base, which is divided into two. In this case, the two fixed bodies may be injection-molded in the same mold, or may be continuously produced automatically in a CNC machine tool. After producing one model like this, the two fixed bodies overlap each other and the lever is interposed between them. When the arm is inserted into the fixing body, grooves formed on the outer circumferential surfaces of both sides of the arm are caught by the side surfaces of the levers, and the arms are caught in the fixing body State.
Therefore, one embodiment of the present invention is advantageous in that productivity can be improved and injection mold ratio can be reduced since a single fixed body is continuously produced and then a pair is assembled so as to face each other.
