Description

Drone station equipped with the function to guide the drone to the correct position

The present invention relates to a drone station equipped with the function of guiding a drone to a fixed position. The electric current unit mounted on the landing skid of the drone is grounded to the charging ground plate of the take-off and landing pad so that the drone can be charged. This relates to a drone station equipped with the function to guide a drone to a fixed location.

A drone is an unmanned aerial vehicle (UAV) shaped like an airplane or helicopter that can fly and be controlled by radio wave guidance without a pilot on board. These drones were developed for military use in the past, but as their prices drop and they become smaller, they are expanding to civilian use. They are used in a variety of fields, including simple flight practice, high-altitude video photography, agriculture and forestry control, delivery, and weather information collection.

When the drone's flight mission is over or the power supply is insufficient, the drone lands at a drone station, and power is supplied from the drone station to the landed drone to charge the drone.

Meanwhile, in recent years, operations such as drone flight, takeoff and landing at the drone station, and drone power charging are performed automatically. However, if the drone does not land at the correct location of the drone station, the drone will not be properly charged. In other words, if the drone fails to land in the correct position at the drone station, the current-carrying unit mounted on the drone skid and the charging ground plate provided at the drone station are not accurately grounded, resulting in a problem in which power is not properly supplied.

Let's look at Korean Patent Registration No. 10-2394878, a prior art that aims to solve the above-mentioned problems.

In the prior art, when a drone lands at a drone station but fails to land at the correct location, the drone can be moved to the correct landing location of the drone station by moving the position of the drone through a movement guide that moves the drone provided at the drone station. Technical features are disclosed.

However, in the prior art, if the landing skid of the drone lands within the range formed by the up-down, left-right, and left-right movement guides, the drone can be positioned correctly. However, in the state where the up-down movement guide and the left-right movement guide are not connected to each other, the guide range of the up-and-down movement guide If the drone lands outside the guide range of the left and right movement guides, or the left and right movement guides are moved after the movement of the up and down movement guides, the drone is caught in the up and down movement guides while being guided by the up and down movement guides, and the drone can no longer move. In situations where this is not possible, a problem may arise where the guide function of the left and right movement guides is disabled.

Therefore, as long as the drone lands on a take-off and landing pad within a certain range, the drone is moved to a fixed location where charging can proceed, but the technical feature is that the drone can be moved while minimizing the problems caused by the above-described prior art. There is an urgent need for research on drone stations equipped with .

In this process, the thickness or size of the components shown in the drawing may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are terms defined in consideration of functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, definitions of these terms should be made based on the content throughout this specification.

Description will be made with reference to FIGS. 1 to 7.

The drone station according to the present invention includes a take-off and landing platform (100) on which the drone (200) takes off and lands, a landing skid movement guide (300), a guide bar (350), a guide power transmission plate (400), and a rack gear and pinion gear (520, 522, 540, 542). and an actuator 600.

The drone 200 may take off or land on the takeoff and landing pad 100.

In order to charge the battery of the drone 200 when the drone 200 lands on the takeoff and landing pad 100, the charging ground where the electrically conductive part 222 mounted on one side of the landing skid 220 of the drone 200 is grounded. Plates 140 may be mounted on the takeoff and landing pad 100 at regular intervals. In other words, this charging ground plate 140 is located at a portion where the energizing part 222 mounted on the landing skid 220 of the drone can be grounded when the drone 200 landing on the takeoff and landing pad 100 is in the correct position. Can be installed.

The landing skid movement guide 300 is mounted on the takeoff and landing platform 100, and may be mounted in multiple numbers. The landing skid 220 of the landed drone can be guided to move to the correct position by the landing skid movement guide 300.

The landing skid movement guide 300 may be mounted to enable straight movement toward a predetermined reference point of the takeoff and landing platform 100. Here, the predetermined reference point of the takeoff and landing pad 100 may be the center of a certain range of the takeoff and landing pad 100 formed by a plurality of charging ground plates 140.

These plurality of landing skid movement guides 300 may be two pairs of landing skid movement guides 300 that are symmetrical to each other with respect to a predetermined reference point of the take-off and landing platform 100. Preferably, a pair of landing skid movement guides 300 are mounted in a diagonal direction based on a predetermined reference point of the takeoff and landing platform 100, and in a diagonal direction above based on a predetermined reference point of the takeoff and landing platform 100. A pair of landing skid movement guides 300 may be mounted in different diagonal directions perpendicular to .

Ultimately, the two pairs of landing skid movement guides 300 may be four landing skid movement guides 300 mounted separately from each other. One landing skid movement guide 300 may be mounted in two diagonal directions based on a predetermined reference point of the takeoff and landing platform 100.

When both of these two pairs of landing skid movement guides 300 move linearly toward a predetermined reference point of the takeoff and landing platform 100, ultimately, the two pairs of landing skid movement guides 300 move linearly toward one point, At this time, the two pairs of landing skid movement guides 300 may move linearly at the same time. Preferably, the two pairs of landing skid movement guides 300 can move linearly at the same time at the same speed by the operation of the actuator 600, which will be described later.

When the two pairs of landing skid movement guides 300 move forward, the take-off and landing platform 100 can simultaneously move linearly toward a predetermined reference point, and when the two pairs of landing skid movement guides 300 move backward, the take-off and landing platform 100 can also move in a straight line. It can be simultaneously moved in a straight line in the opposite direction of the predetermined reference point of (100).

The landing skid movement guide 300 may be composed of a first side 320 and a second side 340 extending from the first side 320 and bent at a certain angle. Each landing skid movement guide 300 is mounted so as to be positioned diagonally based on a predetermined reference point of the takeoff and landing platform 100. Preferably, the first side 320 and the second side 340 are aligned with each other. It can be connected at right angles.

After the drone 200 lands on the front part 101 of the takeoff and landing pad 100, the landing skid movement guide 300 moves straight toward a predetermined reference point of the takeoff and landing pad 100, and the landing skid 220 of the drone The landing skid movement guide 300 is in contact with the landing skid 220 of the drone so that the energizing part 222 mounted on the landing skid 220 of the drone is positioned in a state of being grounded to the charging ground plate 140. can be moved.

That is, the landing skid movement guide 300 may be configured to move in a straight line by a preset distance while the distance to move in a straight line is already preset. Here, the preset distance means that the landing skid movement guide 300 moves by the preset distance. When moving in a straight line, the landing skid 220 of the drone in contact with the drone is moved so that the energizing part 222 can be positioned in a grounded state on the charging ground plate 140, which may be in a preset state.

The landing skid 220 of the drone in contact with the landing skid movement guide 300 moves according to the movement of the landing skid movement guide 300, and once the landing skid 220 of the drone in contact with the landing skid movement guide 300 ), so that it can be moved while properly seated on the landing skid movement guide 300, the landing skid 220 of the drone first needs to be properly seated on the landing skid movement guide 300.

One end 322 of the first side 320 of the landing skid movement guide 300 is not restricted in movement by steps, etc. when the landing skid 200 of the drone in contact moves to the inside of the landing skid movement guide 300. It may be slanted rather than stepped so that it can be guided naturally. The same applies to the end 342 of the second side 340 of the landing skid movement guide 300.

Furthermore, to prevent the landing skid 200 of the drone guided inside the landing skid movement guide 300 from deviating in the upward direction of the landing skid movement guide 300, the top of the landing skid movement guide 300 is attached to the takeoff and landing platform 100. ) may be more protruding in the direction of a predetermined reference point. Accordingly, even if an external force is applied in the upward direction while the landing skid 200 of the drone is located inside the landing skid movement guide 300, its departure can be controlled by this protruding top.

Driving force is required for the landing skid movement guide 300 to move in a straight line at the front part 101 of the takeoff and landing pad, and the components that transmit the driving force to the landing skid movement guide 300 will be described.

A guide hole 120 of a certain length may be formed in the takeoff and landing pad 100 in the direction in which the landing skid movement guide 300 moves linearly. These guide holes 120 may be formed as a pair in a portion where one landing skid movement guide 300 is mounted.

Furthermore, a connection fixing part 150 extending downwardly so as to penetrate the above-mentioned guide hole 120 is coupled to one side of the landing skid movement guide 300, and may be coupled one to each side. This connection fixing part 150 may be moved linearly forward or linearly backward along the guide hole 120.

While one side is coupled to the landing skid movement guide 300, the other side of the connection fixing part 150 may be coupled to the guide power transmission plate 400 located at the rear of the takeoff and landing platform 100. Accordingly, the landing skid movement guide 300 can be moved in a straight line by the movement of the guide power transmission plate 400.

The guide power cutting plate 400 can be moved linearly along the transmission plate guide rail 450 mounted on the rear portion 102 of the takeoff and landing platform 100.

An actuator 600 may be mounted on the rear portion 102 of the takeoff and landing pad 100. Each actuator 600 may be mounted on each landing skid movement guide 300, and the operation of each actuator 600 is controlled by a control unit, but each actuator 600 may be controlled separately. In addition, of course, each actuator 600 can be controlled to operate at the same time with the same power.

By the operation of the actuator 600, the guide power transmission plate 400 can be moved linearly along the transmission plate guide rail 450, and the guide power is applied while the connection fixing part 150 is penetrated through the guide hole 120. Since it is coupled to the transmission plate 400, the landing skid movement guide 300 can ultimately move linearly due to the linear movement of the guide power transmission plate 400.

More specifically, a first rack gear 522 coupled to the rod 610 of the actuator 600, a first pinion gear 520 engaged with the first rack gear 620, and a first pinion gear 520. ), the second pinion lower gear (540-1) is engaged with the second pinion lower gear (540-1), and the rotation axis is coupled so that the rotation axis is the same as the rotation axis of the second pinion lower gear (540-1). A second rack gear 542 may be configured to be mounted on one side of the second pinion gear 540 and the guide power transmission plate 400 and meshed with the second pinion gear 540.

Accordingly, the rod 610 of the actuator is expanded and contracted by the operation of the actuator 600, and the first rack gear 522 mounted on the rod 610 of the actuator is mounted on the rear portion 102 of the takeoff and landing platform 100. It moves linearly along the first rack gear rail (650). The linear movement of the first rack gear 522 rotates the first pinion gear 520 engaged therewith, and this rotational force moves the second pinion lower gear 540-1 engaged with the first pinion gear 520. It is transmitted to the second pinion gear 540 through, and the rotation of the second pinion gear 540 is converted into linear movement of the second rack gear 542 engaged therewith, and eventually the second rack gear 542 is mounted. The guide power transmission plate 400 can be moved in a straight line.

The diameter of the second pinion gear 540 may be larger than the diameter of the first pinion gear 520. In order to enable the second rack gear 542 to move a longer distance through the second pinion lower gear 540-1 and the second pinion gear 540 by moving the rod 610 of the actuator a short distance. am. Accordingly, the landing skid movement guide 300 can satisfy the movement according to the distance to be moved only by moving the rod 610 of the actuator a short distance.

As described above, the plurality of landing skid movement guides 300 are mounted separately, and all of them move in a straight line simultaneously toward a predetermined reference point of the takeoff and landing pad 100. In other words, the landing skid can be moved in a straight line by gathering a plurality of landing skid movement guides 300 at a predetermined reference point of the takeoff and landing pad 100. In order to move in a straight line in a manner in which a plurality of landing skid movement guides 300 are gathered together, the plurality of landing skid movement guides 300 must be separated from each other.

During the process of gathering a plurality of landing skid movement guides (300) toward a predetermined reference point of the take-off and landing platform (100), one landing skid movement guide (300) and another nearby landing skid movement guide (300) are separated from it. When the landing skid 220 of the drone is located between the two, the landing skid 220 of the drone may not be in contact with the landing skid movement guide 300, and as a result, it is difficult to position the drone 200 properly. It can happen.

In order to solve this problem, the drone station according to the present invention is mounted on one landing skid movement guide 300 and another landing skid movement guide 300 among a plurality of landing skid movement guides 300, It may further include a guide bar 350 connecting one landing skid movement guide 300 and the other landing skid movement guide 300.

Furthermore, when the landing skid movement guide 300 moves linearly toward a predetermined reference point of the takeoff and landing platform 100, the guide bar 350 can be configured to slide along one side of the landing skid movement guide 300. there is.

This guide bar 350 has one side in close contact with the first side 320 of one landing skid movement guide 300, and the other side is in close contact with the second side 340 of the other landing skid movement guide 300. It can be configured to slide while in close contact.

A hole 352 may be formed inside the guide bar 350, and a guide roller 310, one side of which is fixedly mounted on the first side 320 or the second side 340, is installed in this hole 352. It can be. That is, while one side of the guide roller 310 is fixed to the first side or the second side 340, the roller portion of the guide roller 310 can be mounted in close contact with the inner surface of the hole 352. .

The diameter of the hole 352 is smaller than the roller diameter of the guide roller 310, and once the guide bar 350 is attached to the first side 320 or the second side 340 by the guide roller 310. The guide bar 340 may be configured so that it cannot be separated from the guide roller 310 in the mounted state.

The guide bar 350 mounted on the second side 340 is configured to slide along the second side 340, and can ultimately be configured to slide while controlled by the guide roller 310. . During the process of sliding the guide bar 350 on the guide roller 310 fixed to the second side 340, a roller among the guide rollers 310 comes into close contact with the inside of the hole 352 of the guide bar 350. As the guide bar 350 rotates, it can guide the sliding movement.

This guide bar 350 connects the plurality of landing skid movement guides 300, and can cover areas that cannot be covered with only the plurality of landing skid movement guides 300.

Furthermore, when a plurality of landing skid movement guides 300 are gathered toward a predetermined reference point of the take-off and landing platform 100, the distance between the landing skid movement guides 300 becomes narrow, and the guide bar 350 is connected to the second side 340. As the guide bar 350 slides along (the other end of the guide bar 350 in close contact with the second side 340 moves outward), the length of the guide bar 350 may be adjusted according to the narrowing gap.

Ultimately, a certain range can be formed on the front part 101 of the takeoff and landing pad 100 by connecting a plurality of landing skid movement guides 300 and the guide bar 350. With the drone 200 landing within this certain range, the area of this certain range narrows due to the movement of the landing skid movement guide 300 and the guide bar 350, and as the area of this certain range narrows, the landing of the drone naturally occurs. The skid 220 is moved, and eventually the drone 200 is positioned in the correct position with the energizing part 222 mounted on the landing skid 220 of the drone grounded to the energizing ground plate 140.

In this state, when comparing the linear movement direction of the landing skid movement guide 300 and the sliding movement direction of the guide bar 350, the landing skid movement is based on the horizontal or vertical direction in which the guide bar 350 is sliding. The guide 300 can be moved linearly in the diagonal direction.

By connecting a plurality of landing skid movement guides 300 and guide bars 350, the drone 200 lands within a certain range formed on the front part 101 of the take-off and landing pad 100, and the landing skid 220 of the drone lands. When located on the side of the skid movement guide 300, the landing skid movement guide 300 moves in a straight line and the end of the landing skid 220 of the drone is moved in the direction of the correct position while in contact with the landing skid movement guide 300. You can.

Since the distance from the predetermined reference point of the takeoff and landing platform 100 to the landing skid movement guide 300 in the diagonal direction is longer than the distance to the guide bar 350, the end of the landing skid 220 of the drone is the guide bar. When located on the (350) side, the guide bar 350 moves and pushes the end of the drone's landing skid 220, and thus the end of the drone's landing skid 220 is pushed toward the landing skid movement guide 300. And, finally, the end of the landing skid 220 of the drone can be seated and moved at the edge of the landing skid movement guide 300 that is the furthest away from the predetermined reference point of the take-off and landing pad 100.

As the landing skid movement guide 300 moves in a straight line, the landing skid 220 of the drone moves with the end seated on the edge of the landing skid movement guide 300, and eventually falls on the landing skid 220 of the drone. The drone 200 is positioned in a state in which the mounted energizing part 222 is grounded to the energizing ground plate 140.

Even if a plurality of landing skid movement guides 300 are gathered toward a predetermined reference point of the take-off and landing platform 100 and reach the final point, the length of the landing skid movement guide 300 is relatively short, so the landing skid movement guide 300 ) are not entangled with each other.

However, when each guide bar 350 slides without direction, the guide bar 350 moved from the landing skid movement guide 300 next to it and the guide moved from the landing skid movement guide 300 below As the bars 350 are gathered into one landing skid movement guide 300, a problem may occur in which multiple guide bars 350 become entangled with each other.

Therefore, when the guide bar 350 is slidably moved, directionality needs to be given to the sliding movement of the guide bar 350 so that the guide bars 350 do not become entangled with each other.

As described above, the landing skid movement guide 300 may be composed of a first side 320 and a second side 340 extending from the first side 320 and bent at a certain angle.

In this state, a trouser support 330 may be formed on the first side 320 to protrude outward to support one end of the guide bar 350 in a contact state, and on the second side 340, a guide bar ( 350) may be without a trouser support so that it can slide without being supported by anything.

Accordingly, when a plurality of landing skid movement guides 300 move linearly toward a predetermined reference point of the takeoff and landing platform 100, one end of the guide bar 350 is the first end of any one landing skid movement guide 300. While in contact with the pants support 330 formed on the side 320, the guide bar 350 may slide along the second side 340 of another landing skid movement guide 300.

That is, when the landing skid movement guide 300 moves linearly toward a predetermined reference point of the takeoff and landing platform 100, the pants support 330 formed on the first side 320 of any one landing skid movement guide 300 While supporting one end of the guide bar 350, the guide bar 350 is pushed toward the second side 340 of the other landing skid movement guide 300. As the pushed guide bar 350 slides on the second side 340 of another landing skid movement guide 300, the other end of the guide bar 350 moves along the second side of the other landing skid movement guide 300. It deviates outward from the side 340.

As the sliding movement of each guide bar 350 is given direction, even if the landing skid movement guides 300 are gathered together, the problem of the guide bars 350 becoming entangled with each other does not occur.

Above, the present invention has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention, but these are merely illustrative examples, and various modifications and equivalent alternatives can be made by those skilled in the art from the embodiments of the present invention. It will be appreciated that embodiments are possible. Therefore, the scope of protection of the present invention should be determined by the scope of the patent claims.
