Description

Technology Field

[0001] The present invention relates to a drone that implements a display in the air. Specifically, the present invention relates to a drone that is structurally designed to be stable to prevent collisions between adjacent drones and is designed with a plurality of light source units to precisely implement an aerial display. Background Technology

[0002] Drones are small unmanned aerial vehicles that are commonly utilized in various fields in modern society, such as photography, reconnaissance, and logistics delivery. Recently, the significance of drone applications is being re-evaluated as they are being used as a new concept media platform to implement large-scale aerial displays. By having multiple drones synchronize and perform cooperative flight, these aerial displays are gaining attention as an innovative technology because, unlike conventional fixed display devices, they can create three-dimensional and colorful video and graphic effects without spatial limitations.

[0003] The basic principle of implementing aerial displays using drones involves equipping individual drones with LED panels, projectors, or other light source devices and synchronizing them via a precise position control and real-time communication system to form a single, integrated video or three-dimensional image. Such a system essentially requires algorithms capable of finely controlling the flight paths and positions of each drone, as well as sensor systems that recognize the surrounding environment and nearby drones.

[0004] Existing drone systems suffer from limitations in terms of lightweight design and durability, resulting in reduced stability of onboard equipment and a risk of damage caused by impact. In particular, it has been pointed out that when multiple drones fly collectively, structural vulnerabilities are easily exposed, and the accumulation of minute errors occurring during flight can lead to a degradation of the overall system's performance.

[0005] Furthermore, drone collisions are one of the biggest safety challenges in implementing aerial displays. Existing technologies lack adequate spacing and collision avoidance systems, resulting in a high risk of mutual collisions when multiple drones fly simultaneously. Since such issues can also arise from drone position control and communication errors, as well as unexpected external factors, the introduction of additional safety mechanisms is required for stable operation.

[0006] Finally, while precise control of the light source devices mounted on each drone is essential for implementing high-resolution displays, existing drone technology has frequently experienced degradation in display quality due to structural limitations aimed at ensuring flight stability and communication delays. These issues stem from complex causes, such as drone synchronization errors, positional inaccuracies, and limitations on data transmission speeds, ultimately negatively impacting the image quality and visual effects of aerial displays.

[0007] Therefore, there is a need for drone technology that enhances structural stability, improves collision avoidance systems, and introduces precision control functions for high-resolution image rendering.

[0008] In this regard, Korean Patent Publication No. 10-2024-0113865 discloses an air drone display. The disclosed document relates to a technology for fixing the air display of a drone in the air as a 2D plane or a 3D stereoscopic image to form a TV monitor. The problem to be solved

The control part may include a pair of side frames formed on both sides of the outer frame and including a truss structure, a body part located on the inner side of the outer frame and connecting the pair of side frames, and a control part connected to the upper surface of the body part and controlling the light-emitting operation of the light-emitting part and the rotational operation of the propulsion part.

Unless otherwise stated, the description in any one embodiment may also apply to other embodiments, and specific descriptions shall be omitted to the extent of overlap.

[0019] FIG. 1 is a perspective view of a drone (1) implementing an aerial display according to an embodiment of the present invention, and FIG. 2 is an upper plan view of a drone (1) implementing an aerial display according to an embodiment of the present invention.

[0020] Referring to FIGS. 1 and 2, a drone (1) according to an embodiment of the present invention can generate a display screen in the air by flying in the air and generating light. For example, a large display panel can be designed in the air by generating various lights on one side of the drone (1) according to an embodiment of the present invention and forming a cluster of multiple drones (1).

[0021] Specifically, one drone (1) generates light of various colors or various shapes on its front surface, and in a state where multiple drones (1) are arranged so that the front surfaces of multiple drones (1) form a single plane, the multiple front surfaces of multiple drones (1) can be implemented as a large display. A central server controls the clustered drones (1) individually so that one light source of one drone (1) functions to become a single pixel, thereby enabling the large display by the drones (1) according to the embodiment of the present invention to precisely transmit the screen.

[0022] In addition, the drone (1) according to an embodiment of the present invention may include a structurally stable form for aerial flight. For example, the drone (1) can further enhance structural stability by placing a component that generates propulsion for aerial flight on the upper side and a component that controls flight movements at the center of gravity.

[0023] In addition, the drone (1) can maintain overall structural balance by designing a truss structure on both sides and stably combining a configuration that controls flight movements with the truss structure.

[0024] Additionally, the drone (1) can be designed to maintain its attitude well during flight by appropriately reflecting a grid frame structure and a frame intersection structure while also arranging a configuration that generates light on the front surface.

[0025] Through this, the drone (1) according to the embodiment of the present invention can reduce shaking during aerial flight and prevent collisions between adjacent drones (1).

[0026] Next, the drone (1) according to an embodiment of the present invention can form a display screen more precisely when implementing a display in the air. For example, the drone (1) can form a plurality of configurations that generate light on the front surface and arrange the plurality of light sources so as to be spaced apart by a certain distance range. In addition, the drone (1) can adjust the amount of light emitted by each of the plurality of light sources to a specific range.

[0027] A drone (1) according to an embodiment of the present invention may include an outer frame (10), a light-emitting part (11), a propulsion part (12), and a control part (13).

[0028] The outer frame (10) can form the exterior of the drone (1). For example, the outer frame (10) may be a plurality of frames designed at the outermost edge. In other words, the outer frame (10) can form the skeleton of the drone (1). That is, the outer frame (10) can be designed in the form of a minimum skeleton necessary for the flight and light generation operations of the drone (1).

[0029] The outer frame (10) may include a material with excellent lightness, shock absorption, or ease of processing. For example, the outer frame (10) may include an aluminum alloy, plastic, or carbon fiber composite material. Additionally, the outer frame (10) may be formed from a 3D printable material such as polycarbonate (PC), ABS, or nylon-based synthetic resin. Using such materials enables rapid prototyping and customized design of the drone structure, and can provide advantageous benefits in terms of implementing complex shapes or reducing weight. Furthermore, wires for interconnecting electrical components such as the light-emitting unit (11), control unit (13), and power supply unit (14) may be inserted and wired inside the outer frame (10). This internal wiring method prevents wires from being exposed to the outside of the drone (1), thereby providing a sense of unity in appearance, while also preventing the wires from coming into contact with external impacts or foreign matter during flight, thereby improving durability and safety. Moreover, since aerodynamic resistance is reduced compared to externally exposed wiring, flight efficiency is also increased.

[0030] As a specific embodiment, a guide groove or cable channel for inserting a wire may be formed inside the outer frame (10). The guide groove may be designed to extend to each part, such as the light-emitting part (11), the control part (13), the propulsion part (12), and the power supply part (14), and may be injection molded into an internal molding structure having a certain cross-section. As a result, the wire is stably fixed without shaking within the frame and can be protected from vibration or shock.

[0031] In addition, considering the installation and maintenance of wires, a part of the outer frame (10) may be designed to be detachable or sliding, and a connector or terminal for wire connection may be embedded in the internal space of the frame so that electrical connection between modules is possible without external exposure. Therefore, the effect is that the replacement or maintenance of modules of the drone (1) becomes easy, and functionality can be maintained without external damage even if wires are repeatedly detached.

[0032] This internal wiring structure goes beyond merely improving aesthetics; it serves as a technical feature that achieves functional advancements in various aspects, including structural stability, electrical reliability, aerodynamic efficiency, and ease of maintenance. In particular, in environments requiring high-density swarm flight for aerial displays, it can enhance overall system reliability by fundamentally eliminating the possibility of failures caused by wire interference between drones or external exposure.

[0033] Additionally, the outer frame (10) may include a cube shape. That is, the outer frame (10) may be a cube shape that forms a hollow space on the inside and is formed as a frame at each corner.

[0034] The light-emitting unit (11) can generate light. For example, the light-emitting unit (11) may be formed on the front surface of the outer frame (10) and may irradiate light toward the front direction of the outer frame (10). Additionally, the light-emitting unit (11) may be composed of a plurality of light sources to generate light of various colors.

[0035] The light-emitting part (11) may include a light-emitting frame (110) and a plurality of light source parts (111).

[0036] A light-emitting frame (110) may be formed on the front surface of the outer frame (10). For example, the light-emitting frame (110) may be formed on a part of the front surface of the outer frame (10). Specifically, based on the view from the front, the outer frame (10) may be formed only as a frame formed along the perimeter of the front surface, and the light-emitting frame (110) on the front surface of the outer frame (10) may be formed only up to a portion that is 2 / 3 of the way from the bottom surface of the outer frame (10) toward the top. A propulsion frame (120), which will be described later, may be formed in the portion of the front surface of the outer frame (10) where the light-emitting frame (110) is not formed.

[0037] Additionally, the light-emitting frame (110) may include a grid frame structure. For example, the light-emitting frame (110) may be formed such that a plurality of frames intersect each other in a cross shape to form an intersection point. That is, based on the view from the front, a plurality of light-emitting frames (110) may be formed perpendicular to the lower surface and side of the outer frame (10).

[0038] A plurality of light source units (111) can generate light independently of each other. Additionally, a plurality of light source units (111) may be formed on the front surface of the outer frame (10) and on the light-emitting frame (110). For example, a plurality of light source units (111) may be formed along the perimeter of the front surface of the outer frame (10) and at the grid points of the grid structure of the light-emitting frame (110). At this time, the plurality of light source units (111) may be spaced apart from each other at a constant interval.

[0039] Specifically, based on the view from the front, a plurality of light source units (111) can be formed by aligning rows and columns while being spaced at equal intervals. That is, the plurality of light source units (111) can be formed in a grid pattern. Preferably, the light source units (111) can be composed of 16 units and arranged in rows and columns in a '4x4' pattern.

[0040] The light source unit (111) may include a light-emitting diode using a semiconductor device that emits light when voltage is applied. For example, the light source unit (111) may generate light in various regions, such as ultraviolet, visible light, or infrared light, by utilizing the electroluminescence effect.

[0041] According to the structure of the light-emitting frame (110) and the structure of the plurality of light source units (111), when a plurality of drones (1) form a cluster to create a large display, each light source unit (111) functions as an independent pixel, allowing for a more precise display screen. Furthermore, according to the structure of the light-emitting frame (110) and the structure of the plurality of light source units (111), even if the drone (1) is hit by wind in the forward and backward directions during flight, the resistance to wind is reduced, thereby increasing the flight stability of the drone (1).

[0042] The propulsion unit (12) can generate propulsion through rotational motion to enable the drone (1) to fly. For example, the propulsion unit (12) is located on the inner side of the outer frame (10) and can function to enable the drone (1) to fly by generating rotational force through a rotating wing configuration.

[0043] Specifically, the propulsion unit (12) may include a propulsion frame (120) and a plurality of rotating blades (121).

[0044] The propulsion frame (120) can be connected to the inner side of the outer frame (10). For example, the propulsion frame (120) can be formed on the upper side of the inner side of the outer frame. That is, as previously described, the propulsion frame (120) can be formed on the upper 1 / 3 portion of the outer frame (10) based on the view from the front. Additionally, the propulsion frame (120) can be formed in a direction parallel to the ground. That is, the propulsion frame (120) can be formed in a direction parallel to the upper and lower surfaces of the outer frame (10).

[0045] The propulsion frame (120) may include a grid frame structure. For example, the propulsion frame (120) may be formed such that a plurality of frames intersect each other in a cross shape to form an intersection point. That is, based on the view from the top, the propulsion frame (120) may be formed perpendicular to the front surface, rear surface, and both sides of the outer frame (10). In other words, the intersecting propulsion frame (120) may be formed in a grid arrangement, so that rows and columns are aligned.

[0046] Multiple rotating blades (121) can generate thrust through rotational motion. For example, the rotating blades (121) are designed in the shape of an airfoil, so that when rotating, they create a pressure difference between the upper and lower surfaces of the blades and push air downwards, thereby causing the drone (1) to rise, move forward, or move backward by the reaction force.

[0047] A plurality of rotating blades (121) may be connected to the upper side of the propulsion frame (120). For example, a plurality of rotating blades (121) may be located at the grid points of the grid structure of the propulsion frame (120). In other words, based on the view from the upper side, a plurality of rotating blades (121) may be located within the area where the outer frame (10) is formed and may be formed symmetrically with respect to the center point of the outer frame (10).

[0048] Specifically, the rotating blades (121) may be composed of a total of four. For example, based on the view from the top, the propulsion frame (120) is divided into a total of 16 areas by a grid-like arrangement, and the four rotating blades (121) may be formed at the intersections of the propulsion frame (120) so as to be symmetrical with respect to the center point of the outer frame (10).

[0049] Additionally, the rotating blade (121) is positioned between the upper surface of the outer frame (10) and the propulsion frame (120), and is positioned on the inner side of the outer frame (10), thereby being protected from collisions with adjacent drones (1) or surrounding obstacles.

[0050] FIG. 3 is a perspective view of a control unit (13) according to an embodiment of the present invention.

[0051] Referring to FIG. 3, the control unit (13) can control the light emission operation of the light-emitting unit (11) and the rotation operation of the propulsion unit (12). For example, the control unit (13) can combine a high-speed processing device such as a microcontroller and an FPGA to precisely control changes in brightness, color, frequency, and pattern of various light-emitting elements, such as LEDs and OLEDs, mounted on the light-emitting unit (11). To this end, the control unit (13) may include a driver circuit and a digital signal processing algorithm for individual control of the light-emitting unit (11).

[0052] Additionally, the control unit (13) can adjust the speed, torque, pitch angle, etc. of the rotating blade (121) in real time through a motor control algorithm and a power control module. For example, the control unit (13) can collect position, attitude, speed, and altitude information of the drone (1) in real time by utilizing various sensors such as an IMU, gyroscope, accelerometer, GPS, and barometer, or a drone-specific module that integrates the above sensors (e.g., FPV Flight Controller), and can precisely control the rotational movement of the propulsion unit (12) through the collected sensor data.

[0053] The control unit (13) may be connected to both sides of the outer frame (10) and located on the inner side of the outer frame (10). For example, when viewed from above, the control unit (13) may be located within the area where the outer frame (10) is formed. In addition, the control unit (13) may be designed to ensure structural stability in terms of the center of gravity of the drone (1).

[0054] Specifically, the control unit (13) may include a pair of side frames (130), a body unit (131), and a control unit (132).

[0055] Side frames (130) can be formed as a pair on both sides of the outer frame (10). That is, the outer frame (10) includes a front side, a rear side, a bottom side, a top side, and both sides, and side frames (130) can be formed as a pair on the sides of the outer frame (10).

[0056] The side frame (130) may include a truss structure. For example, the side frame (130) may include a pair of first side portions (1300) formed upward from the lower surface of the outer frame (10) and inclined so that they become closer to each other as they go upward, and a pair of second side portions (1301) formed upward from the upper side of the first side portions (1300) and inclined so that they become further apart from each other as they go upward.

[0057] Specifically, a pair of first side portions (1300) may be connected to the vertices of the lower and front surfaces of the outer frame (10) or the vertices of the lower and rear surfaces of the outer frame (10), respectively. Additionally, a pair of second side portions (1301) may be connected to the front surface of the outer frame (10) or the rear surface of the outer frame (10), respectively. At this time, the respective connection points where the pair of first side portions (1300) and the pair of second side portions (1301) are connected may be spaced apart from each other at a constant interval.

[0058] Consequently, the side frames (130) can be formed in a shape that gets closer to each other and then further apart as they move from the lower surface of the outer frame (10) upward. In other words, the side frames (130) may include a triangular shape.

[0059] The body portion (131) may connect a pair of side frames (130) and be located on the inner side of the outer frame (10). For example, the body portion (131) may be connected at a connection point where the first side portion (1300) and the second side portion (1301) are connected. The body portion (131) may be connected to each connection point so that each connection point is connected. In other words, the body portion (131) may be connected to a total of four connection points and formed integrally to span across the inner side of the outer frame (10).

[0060] Specifically, the body portion (131) may include a plate shape and be formed in a constant longitudinal direction to cross both sides of the outer frame (10). For example, the longitudinal direction of the body portion (131) may be parallel to the lower surface of the outer frame (10). Additionally, the longitudinal direction of the body portion (131) may be parallel to the front surface of the outer frame (10). Furthermore, the upper surface of the body portion (131) may include a flat surface, and the adjustment portion (132), which will be described later, may be coupled and connected to the upper side of the flat surface of the body portion (131).

[0061] More specifically, the body portion (131) may include a first body portion (1310) that is coupled to the connection point of the first side portion (1300) and the second side portion (1301), and a second body portion (1311) that is formed from the first body portion (1310) to the opposite first body portion (1310), includes a plate shape, and is connected to the adjustment portion (132).

[0062] The control unit (132) can control the light emission operation of the light-emitting unit (11) and the rotation operation of the propulsion unit (12). In other words, the control unit (132) can precisely control the brightness, color, frequency, and pattern changes of various light-emitting elements, such as LEDs and OLEDs, mounted on the light-emitting unit (11) by combining a high-speed processing device such as a microcontroller and an FPGA. In addition, the control unit (132) can adjust the speed, torque, pitch angle, etc. of the rotating blade (121) in real time through a motor control algorithm and a power control module.

[0063] The control portion (132) can be connected to the upper surface of the body portion (131). For example, the control portion (132) can be connected to the upper surface of the body so that the control portion (132) is located within the area where the body portion (131) is formed, based on a view from the upper side.

[0064] The propulsion frame (120) may be located above the second side portion (1301). That is, the propulsion frame (120) may be located above the body portion (131) and the control portion (132). Additionally, when viewed from above, the area where the body portion (131) is formed and the area where the plurality of rotating blades (121) are formed may be different from each other. That is, the rotating blades (121) may not be located above the body portion (131).

[0065] According to the positional relationship between the body part (131) and the rotating wing (121) as described above, when the rotating wing (121) rotates to generate lift, the body part (131) does not act as an obstacle, so the thrust generated by the rotating wing (121) can be acted more effectively.

[0066] A drone (1) according to an embodiment of the present invention may further include a power supply unit (14) that supplies power to a light-emitting unit (11), a propulsion unit (12), and a control unit (13). The power supply unit (14) may be formed as a pair on both lower sides of the body unit (131). For example, when viewed from above, the pair of power supply units (14) may be spaced apart at equal intervals in different directions with respect to the control unit (132). In other words, when viewed from above, the pair of power supply units (14) may be located within the area where the body unit (131) is formed and may be formed symmetrically with respect to the control unit (132).

[0067] A drone (1) according to an embodiment of the present invention may further include a lower frame (15) formed on the lower surface of an outer frame (10). The lower frame (15) may be formed to be connected to each vertex of the lower surface of the outer frame (10) and intersect with one another. That is, the lower frame (15) may be formed diagonally on the lower surface of the outer frame (10). According to the structure of such a lower frame (15), shaking during flight of the drone (1) is reduced, thereby increasing flight stability.

[0068] A drone (1) according to an embodiment of the present invention may further include an upper surface frame (16) formed on the upper surface of an outer frame (10). The upper surface frame (16) may be formed to be connected to each corner of the upper surface of the outer frame (10) and intersect with one another. That is, the upper surface frame (16) may be formed parallel to the corners of the upper surface of the outer frame.

[0069] In addition, when viewed from the upper side, the area where the upper frame (16) is formed and the area where the rotating blade (121) is formed may be different. According to this structure, the upper frame (16) can protect the rotating blade (121) from adjacent drones (1) or the external environment without interfering with the operation of generating propulsion for the rotating blade (121).

[0070] A drone (1) according to an embodiment of the present invention may further include a support frame (17) that connects the upper surface of an outer frame (10) and a propulsion frame (120). The support frame (17) may be formed perpendicular to the upper surface of the outer frame (10) and may be formed in multiple numbers. For example, the support frame (17) may support the grid point portion of the upper surface frame (16) and the portion where the upper surface frame (16) is connected to the upper surface of the outer frame (10). With such a structure, the structural stability of the propulsion frame (120) can be increased.

[0071] On the other hand, the rear surface of the outer frame (10) may form an empty space. For example, there may be no separate frame on the rear surface of the outer frame (10). In other words, the front surface of the outer frame (10) has a light-emitting part (11) formed thereon, but the rear surface of the outer frame (10) corresponding to the front surface of the outer frame (10) where the light-emitting part (11) is formed may be an empty space.

[0072] FIG. 4 shows a drone (1) according to an embodiment of the present invention emitting actual light, and FIG. 5 shows a drone (1) according to an embodiment of the present invention forming a cluster to implement an aerial display.

[0073] Referring to FIGS. 4 and 5, a drone (1) according to an embodiment of the present invention can generate a display screen in the air. In other words, the drone (1) can be formed in multiple numbers to form a cluster and form a large display panel.

[0074] To implement a sophisticated display, a plurality of light source units (111) may be spaced apart from each other at a specific distance, and the light source units (111) may emit light at a specific amount. Specifically, the distance at which the plurality of light source units (111) are spaced apart from each other may be 100 mm to 150 mm. If the distance at which the plurality of light source units (111) are spaced apart from each other is less than 100 mm, the light generated by the plurality of light source units (111) may overlap with each other, and the image quality of the aerial display may be degraded. Conversely, if the distance at which the plurality of light source units (111) are spaced apart from each other exceeds 150 mm, the total area occupied by the drone (1) swarm may become excessively large, increasing the difficulty of controlling the drone (1) swarm that implements the display, and as the spacing between the light source units increases, the spacing between pixels handled by individual drones may also widen, raising concerns that the overall resolution quality of the display may be degraded. This makes precise image representation difficult and disrupts visual continuity, which can negatively affect the completeness of the display implementation.

[0075] Additionally, the amount of light emitted by the light source unit (111) may be 200 lumens (lm) to 300 lumens (lm). If the amount of light emitted by the light source unit (111) is less than 200 lumens (lm), the screen of the aerial display may become dark and the image quality may be reduced. Conversely, if the amount of light emitted by the light source unit (111) exceeds 300 lumens (lm), power consumption increases as a large number of drones (1) are used, and the image time of the display may be significantly shortened.
