Description

[0001] The present invention relates to a flying object capable of flying in rainy conditions,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a unmanned aerial vehicle equipped with a driving motor on a body of a unmanned aerial vehicle.

Many unmanned aerial vehicles are being researched and developed in modern times and are being operated in various industries. Unmanned aerial vehicles (UAVs) and unmanned aerial vehicles (UAVs) have a wide range of applications in the aviation industry. They are also used in conventional unmanned reconnaissance aircraft and unmanned fighter planes for disaster monitoring, relief, meteorological observation, Aerial photography, entertainment, and the like, and is expanding to include more fields.

The conventional unmanned aerial vehicle is constituted by a plurality of motors and electronic components, and is equipped with a drive motor at the outer end of the boom as in Korean Patent Registration No. 1456035, and a propeller is mounted at the upper or lower end of the drive motor to generate lift Method is being used.

In this type of unmanned aerial vehicle, waterproofing of electronic equipment is required for flying in case of rainy weather, but waterproofing is limited due to the motor exposed to the surface. Even if the waterproof coating spraying of electronics is recently produced, The coating is not meaningful due to the physical rotation and heat generated when the waterproof spray is applied. Rather, the coating liquid may be dried and powdered, and may have adverse effect of accumulating foreign matter in the motor.

In addition, as described above, since the propeller is directly fixed to the motor to generate lift, the number of motors and propellers can not be maintained at 1: 1, so that a high output is generated while maintaining a small number of booms In this case, two motors are installed at the upper and lower parts of the boom end, and the propulsive direction of the propeller connected thereto is different from each other to raise the lift. However, due to the obstruction of airflow caused by the reverse rotation of the two propellers, There is a drawback that it is only about 1.5 times the effect of drainage.

Further, when the two propellers rotate in opposite directions, vibration occurs due to the difference between the crossing angle of the two propellers and the minute rotation speed, which may cause the propeller mounting angle to be deformed and cause a failure in flight .

Hereinafter, embodiments of the present invention will be described in detail with reference to FIG. 1 through FIG. 3 and an embodiment.

More particularly, the present invention relates to a unmanned aerial vehicle capable of flying in a rainy day. More specifically, a driving motor is provided at the center of a flying body, and the power is transmitted to a propeller by using a timing pulley, a timing belt and a shaft. The present invention relates to a unmanned aerial vehicle (10) which can fly in a strong wind due to a reduction in the resistance area against wind by using a pair of rotating propellers, thereby facilitating the flight of the unmanned aerial vehicle.

Throughout this specification, the term 'unmanned aerial vehicle' refers to an aeronautical vehicle capable of being remotely controlled without a person on board. In addition, the unmanned aerial vehicle of the present specification may be a commercial aircraft which has been recently commercialized and is called a dragon, a multi-copter, a multi-rotor, or the like.

1 to 3, the unmanned flying vehicle 10 includes a body 100, a plurality of booms 200, a propeller 300, a driving unit 400, and a driving motor 500 .

 1, the body 100 includes an upper plate 101 connected to one side of the boom 200 for fixing and supporting the plurality of booms 200, 102, and the driving motor 500 may be disposed below the lower plate 102.

In addition, it may further include a fixing plate 103 for fixing and supporting the driving motor 500 provided below the lower plate 102. Here, the fixing plate 103 may be provided as a casing that surrounds the driving motor 500, and can prevent a sudden rain, water, or liquid from failing during flight, .

In addition, the main body 100 of the unmanned air vehicle 10 may further include components for remote control.

The plurality of booms (200) of the present invention are radially disposed about the body (100) and extend in the longitudinal direction, and may have a predetermined internal space.

More specifically, the boom 200 may have a hexahedral shape and may form a space in which the driving unit 400 may be provided. However, the boom 200 is not limited to a hexahedral shape.

In addition, the number of the booms 200 is selected from the group consisting of 4, 6, and 8, and when the booms 200 are disposed radially with respect to the body 100, But it is not limited thereto.

For example, when the number of the booms 200 radially provided is four, the angle between the booms 200 may be about 90 degrees when the body 100 is the center. Further, when the number of the booms 200 is six, the angle between each boom 200 may be about 60 degrees. In addition, when the number of the booms 200 is eight, the angle between each boom 200 may be about 45 degrees, but the present invention is not limited thereto.

2, the propellers 300 connected to the respective booms 200 are alternately and alternately arranged in the order of arrows shown in FIG. 2, And may be provided to rotate in the forward / reverse directions.

In addition, the propeller 300 may be provided on the outer side of the end portion of the boom 200, and each of the propellers 300 may be provided on each of the upper and lower portions of the boom 200.

Here, the pair of propellers 300 can rotate in the same direction.

3, the driving unit 400 may include a first timing pulley 401, a second timing pulley 402, a timing belt 403, and a shaft 404. Referring to FIG.

More specifically, when the boom 200 extending from the body 100 in the longitudinal direction is viewed from one end of the body 100 toward the other end of the propeller 300, Is provided with the first timing pulley 401 at one inner side of the boom 200 and the second timing pulley 402 at the other end so that the first The timing pulley 401 and the second timing pulley 402 may be connected and rotated.

In addition, the driving motor 500 is rotatably connected to the first timing pulley 401 to transmit power.

More specifically, the timing belt 403 is rotated by the rotation of the first timing pulley 401 which receives the rotational force generated from the driving motor 500, and the second timing pulley 402 connected thereto is rotated As the shaft 404 rotatably inserted in the center of the second timing pulley rotates, the propeller 300 rotates to generate lift and fly.

The second timing pulley 402 may be connected to the shaft 404 so as to be rotatable with respect to the shaft 404. The shaft 404 may extend outwardly through the boom 200, And a propeller 300 may be connected.

In this case, the shaft 404 is provided with the upper and lower ends of the boom 200 in the reverse direction with respect to the boom 200, and the propeller 300 can be fixed using a fixing means such as a nut.

For example, when the propeller 300 is connected to a shaft having a screw thread direction or a reverse screw direction, the boom 200 is mounted on the upper and lower portions of the shaft 404, The fixing means such as one of the upper and lower nuts of the shaft 404 is loosened by the propeller 300 rotating in the respective co-rotating directions so that the propeller 300 can not be stably fixed.

Therefore, the upper and lower threaded directions of the shaft 404 are formed in opposite directions to each other, thereby preventing loosening of fixing means such as a nut due to rotation of the pair of propellers 300 installed at the upper and lower portions.

 According to the present invention, as described above, since two small propellers 300 are mounted on the upper and lower sides of one shaft 404, there is no physical obstruction between the two propellers 300, The propeller 300 can be mounted on the end of the boom 200 more easily and the mounting angle of the propeller 300 can be maintained at about 90 degrees without vibration of the motor due to the existing motor being directly connected to the propeller It is possible to do.

In addition, by using two small propellers 300, which are one-half the size of a conventional large propeller, the rotational area generated when using a conventional large propeller can be reduced by half, and the propeller 300 Because it rotates in the same direction, the lift generated when one large propeller is used is maintained, but it is possible to fly even in strong winds due to the reduction of the resistance area against the wind due to the reduced cross sectional area reduced by half.

In addition, since the unmanned aerial vehicle using two propellers provided at the lower portion of the existing upper stage uses the propeller rotating in opposite directions, the air flow due to the reverse rotation is obstructed, resulting in a reduction of 1.5 times However, the rotation of the propeller 300 in the same direction according to the present invention makes it possible to increase the lift by two times with the same energy.

In addition, the pair of propellers 300 according to the present invention can use a fixed pitch, and the wings of the propeller are formed so that both of the pair of propellers move in the upward direction when the propeller is rotated. The lift can be adjusted to raise or lower.

For example, the wings of the propeller may use a constant pitch.

In addition, since the conventional unmanned aerial vehicle uses the driving unit 400 as one motor for each boom 200 in contrast to the case where the number of motors and propellers is maintained at 1: 1, The weight can be reduced, the lift can be increased, the energy efficiency can be improved, the flying weight can be reduced, and the flight efficiency can be improved.
