To this end, the present invention provides a unmanned airplane having a plurality of wing portions for generating lifting force on a streamlined gas, and a landing device on a motor shaft having a motor for rotating the propeller at the ends of the wing portions, A motor fixing part for fixing the motor to the end of the motor; A bearing cap rotatably supported by a bearing is provided at an end of a motor shaft of the motor fixed to the motor fixing portion; The bearing cap has a landing portion contacting the ground at a lower end thereof. The motor shaft is rotated at a high speed through the bearing even if the landing portion is in contact with the ground.
Description
The present invention relates to a unmanned airplane having a landing device on a motor shaft. More particularly, the present invention relates to a unmanned airplane having a motor shaft and a motor for rotating the propeller at the end of the wing, And a landing device capable of maintaining a stationary state regardless of the rotation of the motor is vertically installed at an end of the motor shaft. The wing portions serve as a structure for installing the landing device while helping the flight, To a motorized shaft having a landing device.
In recent years, the need for unmanned aerial vehicles is increasing in environments where people can not work. Unmanned aerial vehicles (UAVs) are increasingly needed to provide information on enemy cloaking in aerial image acquisition, aerial photographing, power line inspection or battlefield situations in disaster / disaster areas that are difficult to access, or to carry out reconnaissance missions and surveillance missions through UAV . Also, since the unmanned airplane, which is manufactured in small size, can be easily operated by the general public, its utilization as a playground is gradually increasing.
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 easily and easily assembled and disassembled while firmly fixing the body portion and the lower fixing portion. It is possible to minimize the shock transmitted from the weight of the airplane when the airplane landing, and firmly fix the landing device to the lower fixing unit, thereby further preventing the airplane from being shaken or distorted.
Domestic patent no. 101437323 is also a unmanned airplane, which promptly injects into a fire scene where firefighters can not enter, accurately grasping the fire situation, and equipped with fire fighting equipment to suppress the fire early.
However, these conventional patents have disadvantages in that the structure is complicated and the weight of the gas increases because a separate arm must be separately installed on the base for the landing device. Also, during the flight, there is a problem that the apparatus for folding up the arm for the landing device is not provided so as to obstruct the flight. Conventional unmanned aerial vehicles do not have separate wings, so they fly only by the force of a propeller, which causes a problem that a gas crashes when the propeller is stopped.
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 a wind turbine generator having left and right wings formed on both sides of a base and a tail blade formed at the rear, A landing device capable of maintaining a stationary state regardless of the rotation of the motor is vertically installed at the end of the motor shaft so that the wing portions serve as a structure for installing the landing device while helping the flight, And an unmanned airplane having a landing device on a motor shaft that simplifies the structure because a landing device is installed on the shaft.
To this end, the present invention provides a unmanned airplane comprising a plurality of wing portions for generating lifting force on a streamlined gas, and a landing device on a motor shaft having a motor for rotating the propeller at the ends of the wing portions, A motor fixing part for fixing the motor to the end of the motor; A bearing cap rotatably supported by a bearing is provided at an end of a motor shaft of the motor fixed to the motor fixing portion; The bearing cap has a landing portion contacting the ground at a lower end thereof. The motor shaft is rotated at a high speed through the bearing even if the landing portion is in contact with the ground.
According to the present invention, the left and right wings are provided on both sides of the UAV, and the tail wing is provided on the rear side. These wings generate lift during flight, so even if the output of the motor is adjusted weakly, it is possible to reduce the battery consumption by preventing the fall of the gas. Further, since the motor fixing portion for fixing the motor is provided at the end of each wing portion, a separate arm for mounting the motor is not required.
The end of each of the motor shafts is provided with a landing device that maintains a stop state regardless of the rotation of the motor. The landing device is connected to the motor shaft via a bearing, wherein the inner ring of the bearing is fixed to the motor shaft and the outer ring is fixed to the landing device. Therefore, even if the landing device is placed on the ground and is in the stationary state, the motor shaft is connected to the inner ring and separated from the landing device, so that the operation of the motor is not hindered.
In the unmanned airplane of the embodiment of the present invention, the motors are mounted on the left and right wing portions and the tail wing portions on both sides of the base body, and the landing device is provided at the lower portion of each motor. Therefore, the structure is simple, And the cost of producing airplanes can be reduced.
