The present invention relates to a charging station for wireless charging the drone.

In general, drones are unmanned aerial vehicles operated by radio waves or by their own programs. The drone is equipped with a camera, sensor, and communication system. Drones can range in weight from 25g to 1200kg, and vary in size. Drones were first created for military use, but are being used extensively for aerial photography and delivery. In addition, drones are being used in a variety of areas, including monitoring facilities, monitoring border areas, spraying pesticides, and measuring air quality.

Hereinafter, a wireless charging station for a drone according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In this specification, the same or similar reference numerals are assigned to the same or similar configurations in different embodiments, and the description is replaced with the first description.

1 is a perspective view showing a state in which the drone (D) landed on the wireless charging station 100 for a drone according to an embodiment of the present invention, and FIG. 2 is a lifting driving in the wireless charging station 100 for a drone of FIG. 1 It is a conceptual cross-sectional view showing the operation of the module 130.

Referring to these drawings, the wireless charging station 100 for the drone, the housing 110, the lifting drive module 130, the door module 150, the alignment module 170, and the wireless power transmission module 210 is optional It can contain as.

The housing 110 forms a basic skeleton in which the elevation driving module 130, the door module 150, and the like are installed. The housing 110 may have a substantially rectangular parallelepiped shape. To this end, the housing 110 may have a lower plate 111, a side wall plate 113, an upper plate 115, and a landing plate 117. The side wall plate 113 extends in the height direction from the bottom plate 111 and may form four side surfaces corresponding to the four corners of the bottom plate 111. Accordingly, the lower plate 111 and the side wall plate 113 may form an accommodation space 114 with an open top. The upper plate 115 is generally disposed parallel to the lower plate 111 and is disposed above the side wall plate 113. The landing plate 117 is disposed as a part of the top plate 115, but is separated from the top plate 115, and the drone D is a target for landing. Landing plate 117 is located in the center of the top plate 115, it may be arranged to be surrounded by the top plate 115.

The elevation driving module 130 is configured to elevate the landing plate 117 within the accommodation space 114. The landing plate 117 may be moved in the vertical direction V by the elevation driving module 130. To this end, the elevation driving module 130 may be installed to connect the lower plate 111 and the landing plate 117. As the landing plate 117 is elevated by the lift driving module 130, it is positioned at the same height as the top plate 115 to form one plate therewith, or separated from the top plate 115 to vertically ( It may be located at a height between the top plate 115 and the bottom plate 111 along V). The lifting driving module 130 may specifically include the first link 131, the second link 132, and the lifting driving force generating unit 135. The first link 131 and the second link 132 are rotatably connected to the lower plate 111 and the landing plate 117, respectively, and are disposed in an X-shape crossing each other. The first link 131 and the second link 132 may correspond to both corners of the landing plate 117, and may be provided in pairs. The lifting driving force generating unit 135 is configured to slide one end of one of the first link 131 and the second link 132. The lifting driving force generating unit 135 may be configured by a motor, a ball screw, an LM guide, or the like. When the motor rotates in one direction and the nut of the ball screw moves, one end of the second link 132 connected to the nut also moves in the horizontal direction (H). As a result, the first link 131 and the second link 132 have their connecting points as the central axis of rotation, so that the angle formed between them increases, and the landing plate 117 descends in the vertical direction (V). When the motor rotates in the other direction, the angle formed by the first link 131 and the second link 132 decreases, and the landing plate 117 rises in the vertical direction (V).

The door module 150 is configured to close the landing plate 117 or expose it to the outside. To this end, the door module 150 may include a door 151 that is movably coupled to the sidewall plate 113. The door 151 may specifically include a pair of sliding doors that are slidably coupled to the side wall plate 113. The pair of sliding doors move close to each other along the horizontal direction H or the moving direction to cover the landing plate 117, or move away from each other to expose the landing plate 117 to the outside. To this end, the sliding door includes a cover body 152. The cover body 152 is formed to surround the outside of the side wall plate 113. When the pair of sliding doors are in contact with each other, they form a dome as a whole to cover the landing plate 117.

The alignment module 170 is configured to align the drone D landing on the landing plate 117 for wireless charging. The alignment module 170 may be installed on the housing 110, specifically, the landing plate 117. Alignment module 170 may rotate the drone (D) in a vertical position, or may be moved to a fixed position.

The wireless power transmission module 210 is configured to land on the landing plate 117 and wirelessly charge the drone D aligned by the alignment module 170. To this end, the wireless power transmission module 210 may be installed to access the drone (D) through the landing plate (117). The wireless power transmission module 210 may be configured to have a wireless power transmission pad that transmits a wireless power signal to the wireless power receiving pad of the drone (D).

Now, referring to FIGS. 3 and 4, the alignment module 170 will be described in detail.

3 is a perspective view showing the alignment module 170 of FIG. 1 together with the top plate 115 and the landing plate 117.

Referring to this drawing, the alignment module 170 performs both of rotating the drone (D, see FIG. 1) in an orthogonal position and moving the drone D to the correct position, or by performing one selected among them. (D) is configured to align the wireless power transmission module (210, Fig. 1). The drone (D) is in communication with the communication module 220 and lands on the landing plate 117, so that it is not always arranged to receive the wireless power signal from the wireless power transmission module 210. The role of is needed.

The alignment module 170 may include a rotation induction unit 171 and a movement induction unit 175. If the rotation induction unit 171 is configured to rotate the drone (D) to the drone (D) in a forward position (attitude to look forward), the movement induction unit 175 moves the drone (D) to the correct position It is a configuration to (translate). The attitude and the positioning are those in which the drone D is set in an ordered state to be wirelessly charged effectively by the wireless power transmission module 210. On the other hand, the drone (D) in the state that the drone (D) landed on the landing plate (117) may not be in a posture based on posture and may not be in a fixed position based on position. In that case, the rotation induction unit 171 may operate first and the movement induction unit 175 may operate, or, conversely, the movement induction unit 175 may operate first. Alternatively, depending on the landing state of the drone D, only the movement guidance unit 175 may be operated or only the rotation guidance unit 171 may be operated. For this optional operation, a camera (not shown) for detecting the landing state of the drone D may be additionally installed in the door module 150 (FIG. 1). In this embodiment, the rotation induction unit 171 is first operated to rotate the drone (D) in a forward position, and then the movement induction unit (175) operates to move the drone (D) converted to a forward position into a fixed position. It will be explained mainly.

The rotation induction unit 171 may include a rotation contact member 172. The rotary contact member 172 has a contact surface in contact with the leg of the drone D. The contact surface of the rotary contact member 172 may have a substantially straight shape. The rotating contact member 172 may also be disposed along the Y direction (Y) in the vertical direction relative to the landing plate (117).

The movement induction unit 175 may include a movement contact member 176. The moving contact member 176 also has a contact surface in contact with the leg of the drone D. Unlike the contact surface of the rotary contact member 172, the contact surface of the movable contact member 176 may have a V-shape. The movable contact member 176 may also be disposed along the Y direction (Y).

In the relationship between the rotary contact member 172 and the movable contact member 176, the rotary contact member 172 may be disposed below the movable contact member 176. In addition, the movable contact member 176 and the rotary contact member 172 is in an idle state (state in this drawing) before contact with the drone D, the contact surface of the rotary contact member 172 is that of the movable contact member 176 It may be located closer to the center of the landing plate 117 (the point where the opening 119 is located) than the contact surface. This causes the rotating contact member 172 to contact the leg of the drone D before the moving contact member 176, so that the rotating induction unit 171 affects the drone D before the moving induction unit 175. Go crazy.

The rotation induction unit 171 and the movement induction unit 175 may be provided in pairs, respectively. Accordingly, they can be arranged symmetrically to each other with respect to the center of the landing plate 117. In addition, each pair can move to be close to each other toward the center direction C toward the center from the edge of the landing plate 117. To guide the rotation induction unit 171 and the movement induction unit 175 in the center direction C, the alignment module 170 may further include a guide rail 179. The guide rail 179 is installed on the landing plate 117 and is disposed along the X direction (X), which is the horizontal direction of the landing plate 117. The guide rails 179 may be arranged to form a pair on each side region of the landing plate 117. Unlike the above, the rotation induction unit 171 and the movement induction unit 175 may be provided only one each. In this case, a reference structure (not shown), which serves as a reference for the alignment of the drone D, is installed on the landing plate 117, so that each of the rotation induction unit 171 and the movement induction unit 175 is the reference structure. The drone (D) can be aligned with respect to.

The alignment module 170 may include a landing detection sensor 191, a posture position sensor 195, and a takeoff detection sensor 199 to understand the state of the drone D. Landing detection sensor 191 is installed on the upper plate 115 is a configuration that detects whether the leg (L, see FIG. 1) of the drone (D) is seated on the landing plate (117). The landing detection sensor 191 is an optical sensor having a light emitting unit and a light receiving unit, which irradiates light from the light emitting unit toward the leg L of the drone D and receives the light from the light receiving unit. If the light receiving unit does not receive the light, it may be understood that the drone D has landed. The light-emitting portion and the light-receiving portion extend in the X direction (X), and may be formed to detect the leg L even when the landing position of the drone D is changed. Landing detection sensor 191 may correspond to the two legs (L) of the drone (D), may be respectively arranged on both sides of the opening (119). The posture position sensor 195 is a sensor for grasping whether the drone D is aligned in a forward position and a forward position. The posture position sensor 195 may be installed at the center of the movable contact member 176. The posture position sensor 195, for example, a gap sensor may be used. The takeoff detection sensor 199 is installed on the upper side of the door module 150, and is a sensor for determining whether the drone D takes off from the landing plate 117 and floats over the door module 150. The take-off detection sensor 199 is also formed of a light-emitting unit and a light-receiving unit, and the light-emitting unit and the light-receiving unit may be respectively installed on the door modules 150 on both sides.

FIG. 4 is an assembled perspective view of the alignment module 170 showing an additional configuration related to the alignment module 170 of FIG. 3, and FIG. 5 shows the rotation connecting unit 171 and the moving induction unit of the adjustment connecting member 189 of FIG. 4 (175) is a perspective view showing a connected state.

Referring to these drawings, the rotation induction unit 171 may further include a rotation slider 173. An end of the rotary contact member 172 is connected to the rotary slider 173. The rotating slider 173 is slidably connected to the guide rail 179. Similarly, the movement induction unit 175 may further include a movement slider 177. The moving slider 177 is connected to an end of the moving contact member 176 (FIG. 3). The moving slider 177 is also slidably connected to the guide rail 179. A moving contact member 176 is also coupled to the moving slider 177. The movable contact member 176 may be screwed with the upper surface of the movable slider 177, but this drawing does not indicate it.

The alignment module 170 may further include an alignment driving force generating unit 181 that drives the movement induction unit 175 in the center direction (C, FIG. 3) of the landing plate 117. The alignment driving force generating unit 181 may have a driving source 182, a rotating shaft 184, and a transmission arm 186. The driving source 182 is configured to generate a rotational force, and may be installed on the bottom surface of the landing plate 117. The driving source 182 may be specifically configured to include a motor, a ball screw, a rotating arm connected to a nut of the ball screw, and the like. The rotating shaft 184 is connected to the driving source 182 and rotated, and is disposed to penetrate the landing plate 117. The transmission arm 186 connects the rotating shaft 184 and the moving contact member 176 so that the rotational force generated in the driving source 182 is transmitted to the moving induction unit 175. The connection between the transfer arm 186 and the movable contact member 176 may be made by a connection pin 187 installed at one end of the transfer arm 186. The connecting pin 187 may be rotatably inserted into the movable contact member 176. In the alignment driving force generating unit 181, only the rotating shaft 184 penetrates the landing plate 117, and when the through hole is sealed with a sealing material, foreign matter such as rain is inside the space 114 (FIG. 2). Can lower the likelihood of penetration.

In order to drive the rotary contact member 172 together with the movable contact member 176 in the central direction C, the alignment driving force generating unit 181 may further include an adjustment connecting member 189. The adjustment connecting member 189 is configured to connect the rotating contact member 172 and the moving contact member 176, specifically, the rotating slider 173 and the moving slider 177 to be spaced apart from each other. The adjustment connecting member 189 may have a casing 189a and a damping element (not shown). The casing 189a may be formed in a substantially cylindrical shape. When the rear end of the casing 189a is connected to the moving slider 177, the front end of the casing 189a may be disposed adjacent to the rotation slider 173. The casing 189a has an open slot (not shown) extending along its longitudinal direction, and the rotary contact member 172 extends into the casing 189a through the open slot. The portion of the rotary contact member 172 located inside the casing 189a is elastically supported against the inner wall of the casing 189a by the damping element. The damping element can be, for example, a coil spring.

The alignment process of the drone D according to the above configuration will be described with reference to FIGS. 6 to 10.

First, FIG. 6 is a control block diagram of a wireless charging station 100 for a drone.

Referring to this drawing, the control module 230 is provided for controlling the lift driving module 130, the door module 150, the alignment module 170, the wireless power transmission module 210, and the communication module 220. do. The control module 230 is installed in the interior space 104 and may include a computing device.

The control module 230 may use the detection results of the landing detection sensor 191, the posture position sensor 195, and the takeoff detection sensor 199 when operating the lift driving module 130 or the like.

The specific control method of the control module 230 will be sequentially described with reference to FIG. 7 and the like.

First, FIG. 7 is a partial perspective view of a main part showing a state in which the drone D lands on the landing plate 117 in FIG. 1.

Referring to this drawing, as the drone D has just landed on the landing plate 117, both legs L of the drone D are biased to the right in the figure around the opening 119. In addition, both legs (L) of the drone (D) is rotated clockwise in the drawing, the drone (D) is in a twisted state with respect to the landing plate (117). Accordingly, it can be said that the state of the drone D is out of position and position.

8 is a partial perspective view of a main part showing a state in which one rotation induction unit 171 in contact with the leg L of the drone D in FIG. 7.

Referring to this drawing, the control module 230 determines that the drone D lands on the landing plate 117 through the landing detection sensor 191. Thereafter, the control module 230 operates the alignment drive force generating unit 181 (FIG. 4) in the alignment module 170. According to the operation of the alignment driving force generating unit 181, the rotation induction unit 171 and the movement induction unit 175 are moved in the center direction (C).

As the rotation induction unit 171 and the movement induction unit 175 approach toward the leg L of the drone D, the rotation contact member 172 of the rotation induction unit 171 moves the movement induction unit 175. Prior to the moving contact member 176, the leg L is pressed. Thereby, the drone D is rotated in a twisted posture (counterclockwise on the drawing).

9 is a partial perspective view of a main part showing a state in which both rotation induction units 171 in contact with the legs L of the drone D in FIG. 8.

Referring to this drawing, a pair of rotation induction units 171 located on both sides of the landing plate 117 is provided to both legs L of the drone D by additional operation of the alignment driving force generating unit 181. It comes into contact.

Thereby, the attitude of the drone D can be maintained firmly. Furthermore, the rotation induction unit 171 not only rotates the drone D in a forward position, but also adds a function of moving the drone D in the X direction X or the center direction. Nevertheless, the rotation induction unit 171 is still defined as the rotation induction unit 171 in that the main function is to rotate the drone D.

FIG. 10 is a partial perspective view of a main portion showing a state in which the central portion of the mobile induction unit 175 is in contact with the leg L of the drone D in FIG. 9.

Referring to this drawing, although the alignment driving force generating unit 181 is additionally operated, the rotary contact member 172 reaching the end of the guide rail 179 does not advance further toward the central direction C. The rotating contact member 172 is held in place while being damped by the damping element, and the moving contact member 176 is further moved in the central direction (C). Thereby, the movable contact member 176 comes into contact with the leg L of the drone D. Since the movable contact member 176 has a V-shaped contact surface, the drone D moves in the X direction (X) while simultaneously moving in the Y direction (Y). As a result, the drone D reaches a state in which it is aligned in a fixed position in a normal position as in this figure. This alignment state of the drone D is detected by the posture position sensor 195 and transmitted to the control module 230.

Next, with reference to FIG. 11 (again, FIGS. 1 to 10), the operation method of the drone wireless charging station 100 will be described.

11 is a conceptual diagram showing a method of operating the drone wireless charging station 100.

In the standby state before the drone D approaches the drone wireless charging station 100, the door module 150 is in a closed state closing the landing plate 117 (Fig. 11 (a)).

As the drone D approaches the drone wireless charging station 100, the control module 230 causes the door 151 of the door module 150 to move in the horizontal direction H to expose the landing plate 117. {Fig. 11 (b)}.

When the drone D lands on the landing plate 117, the landing detection sensor 191 detects the leg L of the drone D. Based on the detection result, the control module 230 determines whether the drone D is seated on the landing plate 117. When the leg L is not properly detected, the control module 230 determines that the drone D is not properly seated on the landing plate 117 and communicates with the drone D through the communication module 220 You can force the drone (D) to take off and land again. When the landing detection sensor 191 detects the leg L, the control module 230 operates the alignment module 170, specifically, the rotation induction unit 171 and the movement induction unit 175. Thereafter, the posture position sensor 195 detects whether the drone D is in the correct position, and if it is not, the control module 230 may cause the alignment module 170 to restart (FIG. 11 ( c)}.

If it is determined that the drone (D) is positioned in the correct position, the control module 230 operates the wireless power transmission module 210. Of the wireless power transmission modules 210, the wireless power transmission pad (not shown) rises to approach or contact the drone D, and transmits a wireless power signal to the wireless power receiving pad of the drone D. Furthermore, the wireless power transfer pad is positioned between the two legs L of the drone D to prevent the drone D from being pushed to one side by the wind (Fig. 11 (d)).

The control module 230 controls the lift driving module 130 to lower the landing plate 117 supporting the drone D toward the lower plate 111. Thereby, the drone D is located in the accommodation space 114 (Fig. 11 (e)).

In a state where the drone D is lowered, the control module 230 controls the door module 150 so that the door 151 closes the landing plate 117. Thereby, the wireless power transmission module 210 may wirelessly charge the drone (D) while the drone (D) is located within the closed space by the housing (110) and the door module (150). In order to make this more secure, the control module 230 may lower the landing plate 117 first and allow the wireless power transmission module 210 to operate while the door 151 is closed.

When the drone D is about to take off after wireless charging, the control module 230 may operate the door 151 to close the landing plate 117 based on the detection result of the takeoff detection sensor 199. Thereby, it is possible to prevent the drone D from being damaged because the door 151 is closed while the drone D does not take off properly.

The wireless charging station for a drone as described above is not limited to the configuration and operation of the embodiments described above. The above embodiments may be configured such that all or part of each of the embodiments are selectively combined to make various modifications.
