[0009] (Background to the content of each embodiment) In recent years, the number of places where unmanned aerial vehicles such as drones equipped with various parts such as cameras are used is expanding, and one example is disaster relief sites. In such sites, in order to respond to situations that change from moment to moment, it is necessary to quickly set up and start operating the unmanned aerial vehicle. In addition, at disaster relief sites, workers may wear protective clothing that is not suitable for delicate work for their own protection, so there is a demand for unmanned aerial vehicles to be easily set up without the need for delicate work.

[0010] Therefore, in the following embodiment, an example of an unmanned aerial vehicle that can be installed more quickly and easily is described.

[0011] Hereinafter, with reference to the drawings as appropriate, each embodiment specifically disclosing the unmanned aerial vehicle and storage device according to the present disclosure will be described in detail.

Note that the attached drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] In the following description, when a plurality of equivalent parts are provided, the suffixes a, b, ... are added to the reference numerals, and the suffixes are specified when describing each of them individually. On the other hand, when describing each of them in common, the suffixes are omitted. In the following description, expressions such as "first" and "second" are merely used to distinguish from other components, and are not intended to be interpreted as being limited to a specific part. Therefore, these expressions can be appropriately interpreted according to the configuration, etc. In addition, a three-dimensional coordinate system is shown in the drawings used in the following description, and the orientation of these corresponds to each other in each drawing. In the three-dimensional coordinate system, the X-axis indicates the front-rear direction, the Y-axis indicates the width direction (left-right direction), and the Z-axis indicates the height direction.

[0013] <Embodiment 1> [Equipment configuration] 1 to 7 are perspective views for explaining the appearance and state of an unmanned aerial vehicle 1 according to this embodiment. The unmanned aerial vehicle 1 according to this embodiment includes a main body unit 10, an arm unit 20, legs 30, and a camera 40. Inside the main body unit 10, for example, a control device, a storage device, a battery, a communication device, a sensor device, evacuation equipment, and the like, all of which are not shown, are provided.

[0014] The control device (not shown) may be configured using, for example, a central processing unit (CPU), a graphical processing unit (GPU), a micro processing unit (MPU), a digital signal processor (DSP), or a field-programmable gate array (FPGA). The control device realizes various functions, for example, by reading out various programs and data stored in a storage device (not shown). The storage device is a storage unit for storing various data and programs, and may be configured, for example, from a volatile / non-volatile storage device such as a random access memory (RAM), a read only memory (ROM), or a flash memory.

[0015] The battery is a power source for supplying power to each part in the main body 10 and each motor provided in the arm 20. The communication device is a part for performing wireless communication with an external terminal (for example, an operation terminal described later), and may use any combination of communication standards and frequency bands such as Wi-Fi (registered trademark) and Bluetooth (registered trademark). The sensor device is a part for detecting information on the state of the unmanned aerial vehicle 1 and the surrounding environment, and may include multiple types of sensors. Examples of sensors include a position sensor, a distance sensor, an air pressure sensor, a gyro sensor, an acceleration sensor, a magnetic sensor, and a sound sensor. The position sensor performs positioning using a Global Navigation Satellite System (GNSS), represented by a Global Positioning System (GPS). Examples of evacuation equipment include a parachute device, which is used when an abnormality occurs.

[0016] The unmanned aerial vehicle 1 is provided with a plurality of arm units 20 having an openable / closable structure. In the configuration of this embodiment, an example in which four arm units 20a, 20b, 20c, and 20d are provided is shown. However, this is not limited to this, and three or less or five or more arm units 20 may be provided as long as stable flight is possible. A more detailed configuration example of the arm unit 20 will be described later using FIG. 7. The unmanned aerial vehicle 1 is provided with a plurality of leg units 30 having an openable / closable structure. In the configuration of this embodiment, an example in which two leg units 30a and 30b are provided is shown. However, this is not limited to this, and one or three or more leg units 30 may be provided as long as stable installation and landing are possible. A more detailed configuration example of the leg unit 30 will be described later using FIG. 8.

[0017] The camera 40 is an imaging device for acquiring images of the surroundings of the unmanned aerial vehicle 1. The camera 40 is installed on the main body 10 via a three-axis gimbal, and enables capturing images while suppressing vibration during flight, etc. The camera 40 can pan, tilt, and zoom within a predetermined range based on instructions from a control device. The camera 40 may be an optical camera or an infrared camera. The unmanned aerial vehicle 1 according to this embodiment is equipped with a power cable 50, the details of which will be described later. In response to this configuration, the camera 40 may have its shooting parameters (angle of view, etc.) adjusted so that the power cable 50 is not included in the captured image.

[0018] The unmanned aerial vehicle 1 in this embodiment can be switched by an operator between a state during flight (hereinafter also referred to as the "unfolded state") and a state for storage in a storage device 100 or the like described below (hereinafter also referred to as the "folded state").

[0019] FIG. 1 is a view of the unmanned aerial vehicle 1 in a folded state as viewed from the front side. FIG. 2 is a view of the unmanned aerial vehicle 1 in a folded state as viewed from the side. FIG. 3 is a view of the unmanned aerial vehicle 1 in a folded state as viewed from the bottom side. FIG. 4 shows the state in which the four arm sections 20a, 20b, 20c, and 20d are unfolded from the folded state of FIG. 1. FIG. 5 shows the state in which the propellers 25 provided on each of the four arm sections 20a, 20b, 20c, and 20d are unfolded from the state of FIG. 4. FIG. 6 shows the state in which the two legs 30a and 30b are unfolded from the state of FIG. 5, which is the deployed state.

[0020] FIG. 7 is an external view of the unmanned aerial vehicle 1 in the deployed state, seen from the rear side. A power cable 50 is connected to the rear side of the unmanned aerial vehicle 1 so that power can be supplied from the outside. Therefore, the unmanned aerial vehicle 1 according to this embodiment corresponds to a so-called wired drone. By providing the power cable 50, it is possible to fly for a longer period of time than when only the battery in the main body 10 is used. Note that the battery in the main body 10 may be omitted, and the unmanned aerial vehicle 1 may be operated only by power supply via the power cable 50. In this embodiment, the unmanned aerial vehicle 1 may be allowed to fly within a predetermined range based on the position of the storage device 100 described later, and the length of the power cable 50 may be specified corresponding to this range.

[0021] (Arm section) FIG. 8 is an external view showing a configuration example of the arm unit 20 included in the unmanned aerial vehicle 1 according to this embodiment. As described above, the unmanned aerial vehicle 1 according to this embodiment has four arm units 20a, 20b, 20c, and 20d, all of which have the same configuration. The arm unit 20 is configured to extend from the main body unit 10 and is connected to the main body unit 10 via the connecting unit 21. The connecting unit 21 is configured to be rotatable along a rotation axis defined in the horizontal direction, and this allows the arm unit 20 to transition between the state shown in FIG. 1 and the state shown in FIG. 4. The connecting unit 21 includes a rotation restriction member 21a that restricts the range in which it can rotate. The connecting unit 21 can rotate to a position where the rotation restriction member 21a contacts the main body unit 10. The rotation restriction member 21a may be provided on the main body unit 10 side.

[0022] The connecting part 21 is connected to one end of the columnar member 22, and the fixed member 23 is connected to the other end. The columnar member 22 is configured in a cylindrical shape, and power lines and the like can be passed through the inside of the columnar member 22. The motor unit 24 is installed on the fixed member 23. The motor unit 24 receives a power supply (control signal) from the main body unit 10 side via a power line (not shown) passing through the columnar member 22, and performs a rotational operation. The type of the motor unit 24 is not particularly limited, and for example, a brushless DC (Direct Current) motor or the like may be used. The motor unit 24 is provided with a propeller 25. In this example, an example in which two propellers 25a and 25b are provided is shown. When the motor unit 24 performs a rotational operation, the propellers 25a and 25b connected thereto also rotate. In the unmanned aerial vehicle 1 according to this embodiment, in the deployed state, the propeller 25 is installed vertically below the motor unit 24. Therefore, when in the folded state as shown in FIG. 1, the propeller 25 is disposed so as to face inward, that is, toward the center of the main body 10.

[0023] (leg) FIG. 9 is an external view showing a configuration example of the leg 30 of the unmanned aerial vehicle 1 according to this embodiment. As described above, the unmanned aerial vehicle 1 according to this embodiment has two legs 30a and 30b, both of which have the same configuration. The leg 30 is connected to the main body 10 via the connecting portion 31. The connecting portion 31 is configured to be rotatable along a rotation axis defined in the horizontal direction, and this allows the leg 30 to transition between the state shown in FIG. 4 and the state shown in FIG. 5. The connecting portion 31 is provided with a rotation restriction member 31a that restricts the range of rotation. In addition, a rotation restriction member 31b is also provided on the main body 10 side. The connecting portion 31 can rotate to a position where the rotation restriction member 31a contacts the main body 10. In the opposite direction, the connecting portion 31 can also rotate to a position where a part of the connecting portion 31 contacts the rotation restriction member 31b on the main body 10 side.

[0024] A coupling portion 31 is connected to one end of the columnar member 32, and a connection member 33 is connected to the other end. The connection member 33 connects the columnar member 32 to a columnar member 34. The columnar member 34 has a certain bent shape, and buffer members 35 are installed on both ends of the columnar member 34. The buffer members 35 absorb the impact when the unmanned aerial vehicle 1 lands.

[0025] The material of each part of the unmanned aerial vehicle 1 is not particularly limited. It may be configured to realize durability and light weight, assuming the conditions at the site where it will be used. For example, the pillar member 22 of the arm unit 20 and the pillar member 32 of the leg unit 30 may be made of carbon. In addition, the cushioning member 35 of the leg unit 30 may be made of a sponge material such as polyurethane foam or polyethylene foam.

[0026] [Storage in storage device] The unmanned aerial vehicle 1 according to the present embodiment is used together with a cable winding device 2, a power supply device 3, and an operation terminal 4. The cable winding device 2 is a device for winding up a power cable 50 connected to the unmanned aerial vehicle 1, which is a wired drone. The cable winding device 2 detects slack or tension in the power cable 50 and controls winding or releasing the power cable. The power supply device 3 supplies power to the cable winding device 2 and the unmanned aerial vehicle 1 via the power cable 50. The power supply device 3 only needs to have a device configuration and function related to power supply to the unmanned aerial vehicle 1 and the cable winding device 2, and the configuration is not particularly limited. The power supply device 3 may be an AD / DC converter or a DC / DC converter. The operation terminal 4 is an information processing terminal for controlling the operation of the unmanned aerial vehicle 1. The unmanned aerial vehicle 1 performs, for example, flight control and camera control based on instructions from an operator via the operation terminal 4. The operation terminal 4 may be, for example, a tablet terminal equipped with a touch panel display, a mobile terminal such as a POS terminal, or the like.

[0027] FIG. 10 shows an example of a configuration in which an unmanned aerial vehicle 1, a cable winding device 2, a power supply device 3, and an operation terminal 4 are stored together in a box-shaped storage device 100. For example, in a disaster site, if each device is managed separately, convenience for emergency response decreases. Therefore, each device according to this embodiment is configured to be able to be stored in a single storage device 100. In the storage device 100, cushioning material 5 is provided between each device, and it is configured to suppress contact between the devices.

[0028] Although omitted in Fig. 10, the cable winding device 2 and the power supply device 3 are connected in a state in which electricity can be conducted. Furthermore, even when the unmanned aerial vehicle 1 is in the stored state (folded state), the power cable 50 is connected, and the unmanned aerial vehicle 1 and the power supply device 3 are connected in a state in which electricity can be conducted via the power cable 50.

[0029] When using the unmanned aerial vehicle 1, the unmanned aerial vehicle 1 and the operation terminal 4 are taken out, and the unmanned aerial vehicle 1 is manually deployed as shown in Fig. 6. The desired flight operations can then be performed by operating the unmanned aerial vehicle 1 via the operation terminal 4. Therefore, when using the unmanned aerial vehicle 1, there is no need to take out the cable winding device 2 and the power supply device 3 from the storage device 100.

[0030] The unmanned aerial vehicle 1 is stored in the storage device 100 in a folded state shown in Figs. 1 to 3. In the folded state, the arm unit 20 and the leg unit 30 are configured not to interfere with each other. In addition, the unmanned aerial vehicle 1 is configured so that the propeller 25 side of the arm unit 20, i.e., the side to be inserted into the storage device 100, is narrowed in the folded state. In other words, the rotatable range of the connecting unit 21 is designed so that the propeller 25 side of the arm unit 20 is located closer to the center of the main body unit 10 than the connecting unit 21 side. In other words, in the folded state, the tip of the arm unit 20 is located closer to the center of the main body unit 10 than the connecting unit 21 when viewed from the vertical direction (Z-axis direction). Similarly, the rotatable range of the connecting unit 31 is designed so that the connection member 33 side of the leg unit 30 is located closer to the center of the main body unit 10 than the connecting unit 31 side. At this time, as shown in Fig. 3, it is advisable to arrange the tip of the arm unit 20 on the propeller 25 side so as to be hidden within the range of the leg unit 30 when viewed from below. By configuring in this manner, it is possible to arrange the leg unit 30 so as to prevent the tip of the arm unit 20 from contacting the storage device 100 when storing the unmanned aerial vehicle 1 in the storage device 100. Also, since the propeller 25 is located on the inside in the folded state, it is possible to prevent contact with the propeller 25 from the side when storing the unmanned aerial vehicle 1 in the storage device 100.

[0031] Furthermore, as shown in FIG. 2, the lengths of the arm section 20 and the leg section 30, more specifically, the lengths of the pillar-shaped member 22 of the arm section 20 and the pillar-shaped member 32 of the leg section 30, are specified so that, in the height direction, the tip of the arm section 20 on the propeller 25 side is closer to the main body section 10 than the position of the leg section 30 in the folded state.

[0032] As described above, the unmanned aerial vehicle (e.g., unmanned aerial vehicle 1) according to this embodiment includes a main body (e.g., main body 10), a plurality of arms (e.g., arm sections 20a, 20b, 20c, 20d) that are connected to the main body by a first connecting member (e.g., coupling section 21) and extend from the main body, and a propeller (e.g., 25) that rotates by a motor (e.g., 24) disposed on the free end side of each of the plurality of arms, each of the plurality of arms being configured to be foldable around a rotation axis of the first connecting member defined in the horizontal direction, and the propellers of each of the plurality of arms are located closer to the center of the main body than the arm sections when the provided arms are folded. This configuration makes it possible to provide an unmanned aerial vehicle with improved convenience in handling. In particular, it becomes possible to make the size of the unmanned aerial vehicle compact when stored. Furthermore, it becomes possible to easily remove the unmanned aerial vehicle from the storage device while suppressing contact with the propellers.

[0033] The unmanned aerial vehicle is connected to the main body by a second connecting member (e.g., coupling portion 31) and includes legs (e.g., legs 30) extending from the main body, and the legs are configured to be foldable around the rotation axis of the second connecting member, which is defined in the horizontal direction. This configuration makes it possible to make the size of the unmanned aerial vehicle compact when stored.

[0034] In addition, the arm portions and the legs are configured not to interfere with each other when the arm portions and the legs are folded. With this configuration, the arm portions and the legs do not interfere with each other when the arm portions and the legs are folded, making it possible to prevent damage, etc.

[0035] In addition, when the arms are folded, the free ends of the arms are located closer to the center of the main body than the first connecting member. This configuration makes it easier to remove the arms from and store them in the storage device.

[0036] In addition, when the leg is folded, the free end side is located closer to the center of the main body than the second connecting member side. This configuration makes it possible to easily remove the leg from and store it in the storage device.

[0037] The unmanned aerial vehicle also includes a power cable (e.g., power cable 50) for receiving power from an external source during flight, and a camera (e.g., camera 40), and the camera's imaging range is configured so as not to include the power cable. This configuration allows the camera's imaging range to be determined in accordance with the presence of the power cable.

[0038] Furthermore, the storage device (e.g., storage device 100) stores an unmanned aerial vehicle (e.g., unmanned aerial vehicle 1), an operation terminal (e.g., operation terminal 4) for operating the unmanned aerial vehicle, a cable winding device (e.g., cable winding device 2) for winding up a power cable (e.g., 50) connected to the unmanned aerial vehicle, and a power supply device (e.g., power supply device 3) that supplies power to the unmanned aerial vehicle via the power cable, and the unmanned aerial vehicle is stored in the storage device with the power cable connected, and the unmanned aerial vehicle can be used with the cable winding device and power supply device stored in the storage device. This configuration makes it possible to provide a storage device that can improve the convenience of handling the unmanned aerial vehicle.

[0039] (Other variations) In the above embodiment, an example is shown in which the device has two legs, each of which is T-shaped. However, the present invention is not limited to this, and the device may have, for example, three or more legs, each of which is I-shaped. Also, the device may be configured with a plurality of legs connected to each other, and the portion connecting the legs may be configured to be expandable and contractible when switching between the folded state and the unfolded state. In such a configuration, for example, the portion where the buffer member is provided (corresponding to the connection member 33) may be configured in a circular or rectangular loop shape.

[0040] Furthermore, the storage of the unmanned aerial vehicle 1 and its peripheral devices in the storage device 100 is not limited to the configuration in Fig. 10, and the arrangement may be adjusted as appropriate. For example, when the power supply device 3 is connected to an external power supply source, the storage device 100 may be configured so that a cable for this connection can be further arranged inside the storage device 100. Therefore, the storage device 100 may be configured to have an opening or interface for connecting to an external device, taking into consideration dustproofing, waterproofing, fireproofing, and the like.

[0041] In the above embodiment, an example has been shown in which the shooting parameters are adjusted so that the power cable 50 is not included in the image captured by the camera 40. This is not limited to this, and for example, image processing may be performed to delete the area of ​​the power cable from the captured image, or the orientation of the unmanned aerial vehicle 1 itself may be changed so that the power cable is not included in the captured image.

[0042] The present disclosure also covers programs and storage media that realize the functions of the apparatus of the above-mentioned embodiments and that are supplied to the apparatus via a network or various storage media and that are read and executed by a computer within the apparatus.

[0043] Although various embodiments have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to the examples. It is clear to a person skilled in the art that various modifications, corrections, substitutions, additions, deletions, and equivalents may be made within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present disclosure.
