Description

Technical Field

[0001] The present invention relates to a ring-shaped rotating body and a propulsion body and a drone utilizing the same, and more specifically, to a rotating body driven by electromagnetic force and manufactured in a ring shape to increase the radius of rotation, and a propulsion body and a drone utilizing the same. Background Technology

[0002] Propellers used in drones and similar applications determine their thrust based on the size of the rotation radius and the motor speed. Existing propellers typically have a central rotating motor with blades fastened to it.

[0003] At this point, the area near the motor swept by the blades is inefficient because the swept area is relatively small relative to the motor's rotational speed.

[0004] Therefore, to obtain thrust higher than the revolutions per minute, long blades need to be designed, but there is a problem that long blades cannot be designed arbitrarily. Summary of the Invention

[0043] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings.

[0044] 1. Examples of Ring-Shaped Rotating Bodies

[0045] Figure 1 A diagram illustrating the annular rotating body according to an embodiment of the present invention, Figure 2 To show Figure 1 A longitudinal cross-section of the body of revolution. Figure 3 To show Figure 1 A diagram of the internal structure of a rotating body.

[0046] Reference Figures 1 to 3 The annular rotating body 100 of this embodiment includes a rotating ring 110, a plurality of permanent magnets 120, a fixed ring 130, a plurality of electric coils 140, a control unit 150, and a sealing component 160.

[0047] The rotating ring 110 is a structure that rotates by an electromagnetic force generated in the rotating body 100. (Refer to...) Figure 2 The rotating ring 110 has a tubular structure with a circular cross-section. A through hole 111 extending 360° along its inner circumferential surface is provided in the rotating ring 110. The rotating ring 110 is made of a non-conductive material; for example, it could be made of plastic.

[0048] Multiple permanent magnets 120 are mounted on the inner side of the rotating ring 110. (See reference...) Figure 3Multiple permanent magnets 120 can be arranged at equal intervals. Although six permanent magnets 120 are illustrated in this figure, the number can be varied according to embodiments. The permanent magnets 120 have a curved shape in an arc so that they can be easily mounted on the inner side of the rotating ring 110.

[0049] The retaining ring 130 serves as a core structure for generating electromagnetic force. Therefore, the retaining ring 130 can be made of a magnetic material, such as a metal like iron (Fe). The retaining ring 130 is made in a circular ring shape, as shown in the figure, and can have a circular cross-section. The retaining ring 130 can be fixedly disposed within the internal space of the rotating ring 110.

[0050] Multiple coils 140 are wound and mounted on a retaining ring 130. (Refer to...) Figure 3 Each permanent magnet has two coils 140. Thus, as shown in the figure, with six permanent magnets 120, there are a total of twelve coils 140. The length of each coil 140 is slightly shorter than half the length of each permanent magnet 120.

[0051] The fixing ring 130 can be made of a composite material in which only the portion on which multiple coils 140 are installed is configured as a magnetic body.

[0052] The control unit 150 is a structure that supplies current to and controls the current of the plurality of coils 140, thereby controlling the operation of the rotating body 100. Like the retaining ring 130, the control unit 150 is also fixedly configured. Although not shown, it has a connecting member (not shown) for fixing the control unit 150 to the retaining ring 130.

[0053] The sealing component 160 is a structure that seals the empty space formed in the center of the rotating ring 110. For example... Figure 2 As shown, the cover component 160 can be made into a disc shape, and a control unit 150 can be mounted on its lower side. The cover component 160, as an additional structure for making the appearance of the rotating body 100 appear clean and neat, can be designed in various sizes and shapes according to embodiments, or can be omitted.

[0054] Figure 4 and Figure 5 The diagram illustrates the rotational action and principle of the annular rotating body of the present invention.

[0055] Reference Figure 4 The annular rotating body 100 of the present invention is provided with wires 170 for connecting the control unit 150 and the plurality of coils 140. Current is supplied from the control unit 150 to the plurality of coils 140 through these wires 170. Figure 4As shown, a wire alignment component 180 for assisting wire routing can be additionally provided on the annular rotating body 100.

[0056] like Figure 4 As shown in part (a), the rotating ring 110 can be driven to rotate clockwise, as... Figure 4 As shown in (b), the rotating ring 110 can be driven to rotate counterclockwise. The direction of the current applied to the plurality of coils 140 is controlled by the control unit 150, and the rotation direction of the rotating ring 110 is controlled by controlling the direction of the current.

[0057] Reference Figure 5 When a current I is applied to multiple coils 140, an electromagnetic force F is generated by the interaction between the magnetic field formed therefrom and the magnetic field provided by multiple permanent magnets 120, and the rotating ring 110 is driven to rotate by the rotational torque caused by the electromagnetic force.

[0058] At this time, the direction of the current I applied to the plurality of coils 140 can be controlled in a manner that changes according to the rotational position (angle) of the rotating ring 110. For example, it can be controlled as follows: Figure 5 As shown in part (a), the direction of the current I applied at the position where a pair of coils 140 face the permanent magnet 120 is as follows: Figure 5 As shown in part (b), the direction of the current I applied to a coil 140 is opposite to that of a permanent magnet 120.

[0059] 2. First embodiment of the propulsion system

[0060] Figure 6 A diagram illustrating the propulsion body of the first embodiment of the present invention, Figure 7 To show Figure 6 A longitudinal cross-section of the propulsion body.

[0061] Reference Figure 6 and Figure 7 The propulsion body 201 of the first embodiment of the present invention includes an annular rotating body 101 and a plurality of blades 210.

[0062] The annular rotating body 101 is provided by the annular rotating body 100 of the aforementioned embodiment. Therefore, the annular rotating body 101 has a rotating ring 110 that is driven to rotate around the central axis X.

[0063] Multiple blades 210 are mounted on the rotating ring 110. Therefore, when the rotating ring 110 is driven to rotate, the multiple blades 210 are also driven to rotate.

[0064] like Figure 7As shown, as the multiple blades 210 rotate, a thrust P is generated in the propulsion body 201. At this time, the thrust P acts along the central axis X of the propulsion body 201. Furthermore, the thrust P can act upwards or downwards depending on the rotation direction of the rotating ring 110.

[0065] like Figure 6 and Figure 7 As shown, multiple blades 210 can be manufactured in the existing well-known propeller blade shape.

[0066] According to the propulsion body 201 of this embodiment, since multiple blades 210 are mounted on an annular rotating ring 110, both short-length blades 210 and a large rotation radius R of the propulsion body 201 can be used. Therefore, at the same rotational speed, the propulsion force generation efficiency can be improved.

[0067] Unlike this embodiment, in the case of an existing propulsion body with a conventional rotary motor located at the center and the motor having a structure with blades, the propulsion efficiency is reduced compared to the rotational speed.

[0068] 3. First embodiment of the unmanned aerial vehicle

[0069] Figure 8 A diagram illustrating a drone according to a first embodiment of the present invention.

[0070] Referring to this content, the drone 301 of this embodiment includes a drone body 320 and a plurality of propulsion units 310 connected thereto. The drone body 320 and the propulsion units 310 can be connected to each other via a connecting frame 330.

[0071] Multiple propulsion bodies 310 serve to generate the lift (propulsion) required for the movement of the UAV. The propulsion body 201 of the first embodiment described above can be used as the propulsion body 310 for use in the UAV 301.

[0072] The drone body 320 includes: a power supply unit for supplying the electricity required for the drone to move; and a control unit for controlling the drone's movements.

[0073] In this embodiment, although it is shown that four propulsion bodies 310 are provided in the UAV 301, the number of propulsion bodies 310 provided in the UAV 301 can be varied, for example, two, three, five, six, etc.

[0074] 4. Second embodiment of the drone

[0075] Figure 9 A diagram illustrating a drone according to a second embodiment of the present invention, Figure 10 To show Figure 9 A longitudinal cross-section of the drone.

[0076] Referring to this content, the unmanned aerial vehicle 302 of the second embodiment of the present invention includes a first propulsion body 341 and a second propulsion body 342.

[0077] The first propulsion body 341 and the second propulsion body 342, as structures used to generate the propulsion (lift) required for the movement of the UAV, can be made of... Figure 6 The propulsion body 201 of the aforementioned embodiment is provided. However, the control unit 150 can be provided as a single unit without the need for separate installations in each propulsion body 341, 342.

[0078] The drone 302 of this embodiment has a pair of propellers 341, 342 aligned along the central axis X. When the drone is in motion, it is controlled by rotating the pair of propellers 341, 342 in opposite directions. This cancels out the rotational force generated by the two propellers, making it easier to control the direction of the drone.

[0079] like Figure 9 and Figure 10 As shown, a passenger seat 350 may be provided in the central part of the drone 302. When the drone 302 is made into a manned version, the passenger seat 350 provides space for people to sit. Alternatively, the drone 302 may also be made into an unmanned version, in which case the passenger seat 350 can be omitted since it is not needed.

[0080] 5. Third embodiment of the unmanned aerial vehicle

[0081] Figure 11 A diagram illustrating a drone according to a third embodiment of the present invention, Figure 12 To show Figure 11 A longitudinal cross-section of the drone.

[0082] Referring to this content, the unmanned aerial vehicle 303 of the third embodiment of the present invention includes a single propulsion body 341.

[0083] The single propulsion body 341, as a structure used to generate the propulsion (lift) required for the movement of the UAV, can be composed of, for example... Figure 6 The propulsion body 201 of the aforementioned embodiment is provided.

[0084] The drone 303 in this embodiment may have only one propulsion body 341, and may be configured using an additional device to counteract the rotational force generated in the direction opposite to the rotational direction of the propulsion body blades or a directional control method of the drone body itself.

[0085] like Figure 11 and Figure 12As shown, a passenger seat 350 can be provided in the center of the drone 303. When the drone 303 is made into a manned version, the passenger seat 350 provides space for people to sit. Alternatively, the drone 303 can also be made into an unmanned version, in which case the passenger seat 350 can be omitted since it is not needed.

[0086] 6. Second embodiment of the propulsion system

[0087] Figure 13 A diagram illustrating the propulsion body of the second embodiment of the present invention, Figure 14 To show Figure 13 A longitudinal cross-section of the propulsion body.

[0088] Referring to this content, the propulsion body 202 of the second embodiment of the present invention includes an annular rotating body 101 and a plurality of blades 220.

[0089] The annular rotating body 101 is provided by the annular rotating body 100 of the aforementioned embodiment. Therefore, the annular rotating body 101 has a rotating ring 110 that is driven to rotate around the central axis X.

[0090] Multiple blades 220 are mounted on the rotating ring 110. Therefore, when the rotating ring 110 is driven to rotate, the multiple blades 220 are also driven to rotate.

[0091] like Figure 14 As shown, as multiple blades 220 rotate, a thrust P is generated in the propulsion body 202.

[0092] like Figure 13 and Figure 14 As shown, the multiple blades 220 are configured with multiple shells arranged at equal intervals along the central axis. The size of the multiple shells decreases as they approach the center. In the accompanying drawings, the multiple blades 220 are composed of 3 shells, but the number of shells can vary in various embodiments, such as 4, 5, 6, etc.

[0093] Each blade 220 has eight fluid through-holes 230 arranged at equal intervals along the circumference. The number of fluid through-holes 230 can be varied depending on the embodiment. When the propulsion body is running, the multiple blades 220 rotate together with the rotating ring 110. At this time, fluid (such as air) from the upper part of the propulsion body flows into the propulsion body through the multiple fluid through-holes 230. The inflowing fluid is branched by multiple outer casings and discharged downwards. With this fluid flow, a pressure greater than that on the upper side is formed on the lower side of the propulsion body 202, and the upward thrust is generated by means of this pressure difference.

[0094] Preferably, the fluid through-hole 230 is configured to be as close as possible to the rotating ring 110.

[0095] According to the propulsion body 202 of this embodiment, since the structure is that the outer shell-shaped blades 220 are mounted on the annular rotating ring 110, a larger rotation radius R can be ensured compared to the case where a conventional rotary motor is used as the rotational force generating mechanism. Therefore, at the same rotational speed, the propulsion force generation efficiency can be improved.

[0096] Figure 15 To show Figure 13 and Figure 14 A diagram showing an alternative embodiment of the propulsion system.

[0097] Referring to this content, among the multiple housings of the blade 220, the innermost housing does not have a fluid passage 230, thereby preventing backflow of air.

[0098] Figure 16 To show Figure 13 and Figure 14 A diagram showing another alternative embodiment of the propulsion system.

[0099] Referring to this content, preferably, the fluid through-hole 230 provided in the blade 220, which is in the shape of a shell, is located as close as possible to the center of the propeller 202. Therefore, the fluid through-hole 230 can be located in the blade 220 in a region close to the center of the propeller, that is, in Figure 16 The region is represented in a flat manner.

[0100] 7. Fourth embodiment of the unmanned aerial vehicle (UAV)

[0101] Figure 17 A diagram illustrating a drone according to a fourth embodiment of the present invention.

[0102] Referring to this content, the drone 304 of the fourth embodiment of the present invention includes a drone body 320 and a plurality of propulsion units 360 connected thereto. The drone body 320 and the propulsion units 360 can be connected by a connecting frame 330.

[0103] Multiple propulsion units 360 serve to generate the lift (propulsion) required for the drone's movement. Figure 13 and Figure 14 The propulsion body 202 of the second embodiment shown can be used as a propulsion body 360 for driving a drone.

[0104] The drone body 320 includes: a power supply unit for supplying the electricity required for the drone to move; and a control unit for controlling the drone's movements.

[0105] In this embodiment, although it is shown that four propulsion bodies 360 are provided in the drone 304, the number of propulsion bodies 360 provided in the drone 304 can be varied, for example, 2, 3, 5, 6, etc.

[0106] 8. Fifth embodiment of the unmanned aerial vehicle (UAV)

[0107] Figure 18 A diagram illustrating a drone according to a fifth embodiment of the present invention is provided. Figure 19 To show Figure 18 A longitudinal cross-section of the drone.

[0108] Referring to this content, the UAV 305 of the fifth embodiment of the present invention includes a first propulsion body 371 and a second propulsion body 372.

[0109] The first propulsion body 371 and the second propulsion body 372, as structures for generating the propulsion (lift) required for the movement of the UAV, can be made of... Figure 13 and Figure 14 The propulsion body 202 of the second embodiment shown is provided. However, the control unit 150 can be provided in a combined form, without the need to be separately provided in each propulsion body 371, 372.

[0110] The drone 305 of this embodiment has a pair of propellers 371, 372 aligned along the central axis X. When the drone is in motion, it is controlled by rotating the pair of propellers 371, 372 in opposite directions. This cancels out the rotational force generated by the two propellers, making it easier to control the direction of the drone.

[0111] like Figure 18 and Figure 19 As shown, a passenger seat 350 can be provided in the center of the drone 305. When the drone 305 is made into a manned version, the passenger seat 350 provides space for people to sit. Alternatively, the drone 305 can also be made into an unmanned version, in which case the passenger seat 350 can be omitted since it is not needed.

[0112] Figure 20 To show Figure 18 and Figure 19 A diagram showing an alternative embodiment of the drone.

[0113] Referring to this content, an air inlet 380 is provided between the central portion of the drone 305, where the cover component 160 or passenger seat 350 is located, and the first propulsion body 371, so that air can be supplied to the upper part of the drone to the second propulsion body 372. The shape and size of the central portion of the drone, such as the cover component 160 and passenger seat 350, can be appropriately modified to provide the air inlet 380.
