Description
Drones that provide lighting functions
[0001] The present invention relates to a drone providing a lighting function, and more particularly, to a drone for replacing an aerial flare.
[0002] Aircraft flares are designed to provide visibility to friendly infantry during nighttime military operations. They are dropped from approximately 6,000 feet, enter a freefall, and then, at approximately 3,000 feet, a timer activates and a parachute is released, providing visible or infrared illumination to the ground. However, aircraft flares have limited illumination duration, making them insufficient for military operations. Furthermore, their use can cause environmental pollution due to the use of flammable materials. Therefore, there is a need to develop environmentally friendly products that provide long-lasting illumination. Lighting drones are gaining attention as an alternative to aircraft flares.

[0030]
[0031] Hereinafter, with reference to the drawings, a drone (1) providing a lighting function according to the present invention will be described.
[0032]
[0033] First, in order to explain that the drone (1) providing the lighting function of the present invention is intended to replace an aerial flare, the process of using the drone (1) will be described.
[0034] The drone (1) is loaded onto an aircraft and enters the operational area at an altitude of 6,000 feet. The drone (1) is then released from the aircraft. At this time, it descends vertically to approximately 1,000 feet, after which the lighting is activated to begin providing illumination to the ground. In other words, the drone (1) of the present invention must be manufactured with a structure that facilitates vertical descent from high altitude to low altitude, and must be durable enough to withstand friction with the air caused by vertical descent.
[0035]
[0036] Figures 1 to 4 illustrate a drone (1) according to one embodiment of the present invention.
[0037]
[0038] A drone (1) providing a lighting function according to one embodiment of the present invention includes a main body (10), a rotating part (20) coupled to the upper end of the main body (10) and including a propeller (23), and a lighting part (30) coupled to extend downward from the lower end of the main body (10), and the propeller (23) is capable of folding toward the main body (10).
[0039]
[0040] A drone (1) according to one embodiment of the present invention includes a main body (10), a rotation part (20), and a lighting part (30). The main body (10) is a component that protects major essential components and serves as a central structure of the drone (1). The rotation part (20) includes a propeller (23) and, by rotating, serves to generate lift for the drone (1). The lighting part (30) is a component that performs a lighting operation for the ground and is a component that emits visible light or infrared rays. The rotation part (20) and the lighting part (30) are respectively arranged in the vertical direction centered on the main body (10).
[0041] At this time, as shown in Fig. 3, the propeller (23) can be folded toward the main body (10). The reason why the propeller (23) is equipped with a folding function is that, due to the nature of the drone (1) of the present invention being transported by aircraft, ease of storage is important, and thus, reducing the volume of the drone (1) is essential. In addition, the drone (1) of the present invention must descend vertically from a high altitude, and thus, durability to withstand large friction with the air is important. Therefore, when descending, it is necessary to protect the propeller (23) portion, which is relatively weak in durability, and accordingly, a folding function of the propeller (23) can be equipped on the drone (1) to minimize concerns about damage due to ground resistance by folding the propeller during descent.
[0042]
[0043] In a drone (1) providing a lighting function according to one embodiment of the present invention, the main body (10) may include a cylindrical housing (11), a motor unit (12) disposed adjacent to the upper end of the main body (10) inside the housing (11) to transmit rotational force to the rotating unit (20), and a power supply unit (13) disposed inside the housing (11) to supply power to the motor unit (12) and the lighting unit (30).
[0044]
[0045] The main body (10) of a drone (1) according to one embodiment of the present invention may include a housing (11), a motor (12), and a power supply (13).
[0046] The housing (11) can be manufactured in a cylindrical shape to minimize air resistance when the drone (1) vertically descends.
[0047] Referring to Fig. 5, the configuration formed inside the main body (10) can be seen. A motor unit (12) and a power supply unit (13) can be formed inside the main body (10). The motor unit (12) is formed adjacent to the upper part of the main body (10) to transmit the rotational power of the rotation unit (20). The power supply unit (13) can be formed as a battery, and the power supply unit (13) is formed so as to be able to supply power to the lighting unit (30) and the motor unit (12).
[0048]
[0049] In a drone (1) providing a lighting function according to one embodiment of the present invention, the rotating part (20) may be formed to be smaller than the diameter of the housing (11), and may include a central rotating body (21) that receives power from the motor part (12) to rotate, and a hinge part (22) that extends outward from the central rotating body (21) and rotates so that the propeller (23) can be folded so as to be in close contact with the main body part (10).
[0050]
[0051] The rotating part (20) of the drone (1) according to one embodiment of the present invention may include a central rotating body (21), a hinge part (22), and a propeller (23).
[0052] The central rotating body (21) is configured to rotate by receiving power directly from the motor unit (12), and is positioned above the upper portion of the main body unit (10). Referring to Fig. 4, the hinge unit (22) is configured to allow the propeller (23) to fold toward the main body unit (10), and is formed to extend toward the outside from the central rotating body (21).
[0053]
[0054] In a drone (1) providing a lighting function according to one embodiment of the present invention, the central rotating body (21) may include a lower rotating body (21a) having a cylindrical structure that directly receives rotational force from the motor unit (12) and extends upward from the upper end of the main body unit (10), and an upper rotating body (21b) formed as a cylindrical structure that is larger than the diameter of the lower rotating body (21a) and smaller than the diameter of the housing (11), and is formed integrally with the lower rotating body (21a) to rotate, and is coupled to the hinge unit (22).
[0055]
[0056] According to an embodiment of the present invention, the central rotor (21) of the drone (1) includes a lower rotor (21a) and an upper rotor (21b). Referring to FIG. 3, the lower rotor (21a) has a structure extending upward from the upper end of the main body (10), and can be seen to have a smaller height than the upper rotor (21b) and the main body (10). The upper rotor (21b) is formed to have a diameter larger than that of the lower rotor (21a) and smaller than that of the housing (11). The reason why the diameter of the upper rotor (21b) is formed to be smaller than that of the main body (10) is to minimize air resistance when the drone (1) vertically descends. In addition, the gap between the upper rotor (21b) and the upper end of the housing (11), i.e., the height of the lower rotor (21a), may be formed to be 1 / 5 or more and 1 / 4 or less of the height of the upper rotor (21b). This means that if the gap between the upper rotor (21b) and the upper part of the housing (11) is formed to be less than 1 / 5 of the height of the upper rotor (21b), air resistance due to the rotation of the upper rotor (21b) may be amplified due to the configuration of the main body (10), which may reduce drone flight efficiency, and if the gap between the upper rotor (21b) and the upper part of the housing (11) is formed to be more than 1 / 4 of the height of the upper rotor (21b), air may enter the space between the upper rotor (21b) and the main body (10) when the drone (1) vertically descends, which may weaken the durability of the rotating part (20).
[0057]
[0058] In a drone (1) providing a lighting function according to one embodiment of the present invention, the main body (20) may include a navigation sensor (14) that measures air pressure and altitude and a control unit (15) that controls the flight of the drone (1).
[0059]
[0060] Referring to FIG. 5, a navigation sensor (14) and a control unit (15) may be arranged inside the main body (20) of a drone (1) according to an embodiment of the present invention. The navigation sensor (14) measures the altitude of the drone (1) and measures the air pressure around the drone (1) to enable the drone (1) to operate at an appropriate altitude. The control unit (15) controls the flight of the drone (1), and in particular, performs flight control during vertical descent or mission execution. The control unit (15) may also be capable of performing a step-by-step mission according to the remaining battery level in order to perform an input mission.
[0061]
[0062] In a drone (1) providing a lighting function according to one embodiment of the present invention, the lighting unit (30) may include a light emitting unit (31) that emits visible light or infrared light and a lighting housing (32) that surrounds the light emitting unit (31) and has an upper portion that matches the diameter of the housing (11) but increases in diameter as it goes downward.
[0063]
[0064] A lighting unit (30) according to one embodiment of the present invention may include a light emitting unit (31) and a lighting housing (32).
[0065] The light emitting unit (31) is configured to emit visible light or infrared light. The light housing (32) can be configured to have a diameter that increases as it goes downward while being connected to the lower end of the housing (11). This is to control the speed of vertical descent while protecting other components of the drone (1) by having the light housing (32) receive air resistance when the drone (1) vertically descends. To this end, the drone must be dropped so that the light housing (32) faces downwards. The heaviest component among the components of the drone (1) is the power supply unit (13) composed of a battery. By arranging the power supply unit (13) adjacent to the light supply unit (30) as shown in FIG. 5, the center of gravity of the drone (1) can be moved downward. Therefore, when the drone (1) vertically descends, the light housing (32) experiences air resistance, thereby protecting other components of the drone (1).
[0066]
[0067] According to one embodiment of the present invention, a rotating part (20) of a drone (1) may additionally be provided with a fixing member (24) that is coupled between the propeller (23) and the hinge part (22) and serves to fix the propeller (23) while rotating about the hinge part (22). By separating the screw formed in the fixing member (24), the propeller (23) may be stored separately from the rotating part (20).
[0068]
[0069] Although the present invention has been described in detail through specific examples, this is intended to specifically explain the present invention, and the present invention is not limited thereto, and it will be apparent that modifications and improvements can be made by those skilled in the art within the technical spirit of the present invention.
[0070] All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be made clear by the appended claims.
