JP 2019-23020 A

However, when the delivery destination has limited space, such as an average home, it is difficult to provide a drone port to receive a drone or a space for the drone to land. On the other hand, there is a demand for technology that enables delivery by drone even when the delivery destination has limited space.

In view of these issues, the present invention aims to provide a delivery box that enables delivery by drone even when the delivery destination has limited space.

The present invention provides the following solutions.
A delivery box having a storage space for storing items that can be delivered, which is installed on both the inside and outside of an exterior wall of a building, and which can be delivered from above by a flying drone,
a storage section that protrudes outward from the outer wall of the building, forms the storage space whose inside can be cooled by a cooling device, and has openings on the inside and outside of the building through which the object to be stored can be put in and taken out of the storage space;
an opening/closing unit that opens and closes the opening,
The opening disposed on the outside of the building is open upward,
The opening located inside the building is formed in a box shape open at the top, can be inserted and removed from the storage space, and is opened and closed by a drawer that can pull the items stored in the storage space formed outside the exterior wall of the building inward from the exterior wall of the building.

The present invention makes it possible to provide a delivery box that enables delivery by drone, even when the delivery destination has limited space.

Below, a detailed description of the mode for carrying out the present invention (hereinafter, the embodiment) will be given with reference to the attached drawings. In the following figures, the same elements are given the same numbers or symbols throughout the description of the embodiment.

(Exterior configuration)
1, 2, 3 and 4 are diagrams illustrating the external configuration of a delivery box according to an embodiment of the present invention.
Figures 1 and 2 show an example of a delivery box 1 installed in a detached building such as a house, where Figure 1 is a view of the delivery box 1 from the outside of building B and Figure 2 is a view of the delivery box 1 from the inside of building B.
Figures 3 and 4 show an example of a delivery box 1 installed in a building B (e.g., an apartment building) that is higher than a detached house, with Figure 3 being a view of the delivery box 1 from the outside of building B and Figure 4 being a view of the delivery box 1 from the inside of building B.

In the example shown in Figures 1 and 3, the delivery box 1 stores luggage (items L) delivered by a delivery company device 150 (e.g., an aerial drone, etc.) that transports luggage (items L) ordered by a user from a luggage collection point W operated by a delivery company.

1 and 3 show an example in which a delivery company uses a delivery person's device 150 (e.g., a flying drone, etc.), but the items to be stored in the delivery box 1 may be delivered by a person. Also, in the example shown in FIG. 1 and 3, the delivery person's device 150, which is a flying drone, suspends the item L with a wire and places it in the delivery box 1. However, this is not limited to this. For example, if the item L is a relatively light item such as medicine, the item L may be held directly by the delivery person's device 150 without using a wire, and the delivery person's device 150 may be lowered to the vicinity of the delivery box 1, and then the delivery person's device 150 may release its hold on the item L and drop the item L into the delivery box 1. Also, the delivery person's device 150 is not limited to a flying drone, and may be any device such as an automatically driven automobile.

The delivery box 1 has a storage space S for storing items that can be delivered, and is equipped with a storage section 2 and an opening/closing section 3.

The storage unit 2 forms a storage space S inside and has an opening 21 through which the stored object L can be put in and taken out of the storage space S. It is preferable that the storage unit 2 forms the storage space S with an exterior member having thermal insulation properties. This makes it possible to store the stored object L stored in the storage space S in a frozen or refrigerated state. The storage unit 2 may also be equipped with a cooling device that cools the storage space S.

Furthermore, it is preferable that the delivery box 1 is provided, for example, on both the inside and outside of the exterior wall of the building B. In this case, it is preferable that the storage section 2 has an opening 21 on both the inside and outside of the building B. The opening 21 provided on the outside of the building B is open toward the top. Furthermore, the opening 21 provided on the inside of the building B is open toward the horizontal direction.

The opening/closing section 3 includes an opening/closing door 31 that opens and closes the opening 21 provided on the outside of the building B, and a drawer 32 that opens and closes the opening 21 provided on the inside of the building B and can be inserted and removed from the storage space S.

The opening/closing door 31 is connected to the storage unit 2 so that it can rotate around a rotation axis whose side edge extends horizontally, and opens the opening 21 upward by rotating upward. The opening/closing door 31 may also open and close the opening 21 under the control of the control unit 10 (see FIG. 5), which will be described later.

The drawer 32 is formed in a box shape with an open top and includes a bottom plate that is inserted into and removed from the storage space S, side plates that stand upright from the side edges of the bottom plate, a front plate that stands upright from the tip of the bottom plate, and a front plate that stands upright from the front end of the bottom plate and opens and closes the opening 21 provided inside the building B.

By configuring the opening/closing section 3 in this manner, the opening/closing door 31 opens outside the building B, and the user can remove the stored item L stored in the storage space S from above the opening 21 by pulling out the drawer 32 from the storage space S inside the building B.

(Functional configuration)
FIG. 5 is a diagram showing the functional configuration of the delivery box according to the embodiment of the present invention.
The delivery box 1 is equipped with a control unit 10, an operation reception unit 20, and a weighing unit 30, and is connectable via a network to an order reception server 100 that receives orders from users for items (contained items L) that they wish to have delivered, a delivery device 150 (e.g., an aerial drone, etc.) that transports the luggage (contained items L) ordered by the user, and a user terminal 50 (e.g., a smartphone, etc.) operated by the user.

The control unit 10 includes an order reception unit 11, a communication unit 12, an opening/closing unit 13, and a notification unit 14.

The order reception unit 11 receives the order details for the contained items L based on the operation reception unit 20 (see FIG. 2) or user operations via the user terminal 50, or the weighing results of the weighing unit 30, generates order information indicating the order details, and stores it in a storage means.

The communication unit 12 transmits the order information generated by the order reception unit 11 to the order reception server 100. The order information includes product information indicating the product to be contained in the item L, quantity information indicating the quantity of the product, location information indicating the location of the delivery (location information indicating the location of the delivery box 1), etc. When the order reception server 100 receives the order information, the delivery company delivers the contained item L to the delivery box 1 based on the order information, for example, by the delivery company device 150. Note that if location information indicating the location of the delivery (location information indicating the location of the delivery box 1) has been registered in advance in the order reception server 100, the order information does not need to include location information.

The opening/closing unit 13 includes an opening/closing mechanism that opens and closes the opening/closing door 31 (see Figures 1 and 3). The opening/closing mechanism includes a motor, a link mechanism that rotates the opening/closing door 31 by the driving force of the motor, and a door control unit that controls the motor. The door control unit drives the motor to open and close the opening/closing door 31 based on the operation of the user or delivery company at the operation reception unit 20 (see Figures 1 and 3). In addition, the door control unit may receive, for example, request information requesting that the opening/closing door 31 be opened from the delivery company device 150 (e.g., an airborne drone, etc.), and open and close the opening/closing door 31 when the request information is received.

The notification unit 14 notifies that the contained item L has been stored in the storage space S of the storage unit 2. For example, when the contained item L is stored in the storage space S, the notification unit 14 transmits delivery completion information indicating that the delivery of the contained item L has been completed to the operation reception unit 20 (see FIG. 2) or the user terminal 50. When the operation reception unit 20 or the user terminal 50 receives the delivery completion information, it displays on the display means that the delivery of the contained item L has been completed, or outputs a sound from the sound output means. This makes it possible to notify the user that the delivery of the contained item L has been completed.

The operation reception unit 20 includes reception means (e.g., buttons, touch panels, etc.) for receiving operations from a user or delivery company, display means (e.g., touch panels, displays, etc.) for displaying a screen based on operations from the user or delivery company, audio output means (e.g., speakers, etc.) for emitting sound, audio acquisition means (e.g., microphones, etc.) for acquiring sound, transmission means for transmitting various information received by the reception means to the control unit 10 via wired or wireless communication, and control means for controlling these various means.

The operation reception unit 20 may also, for example, acquire a user's voice order using a voice acquisition means, analyze the acquired voice using a control means, and transmit the analyzed order content to the order reception unit 11 of the control unit 10 using a transmission means.

The operation reception unit 20 may also be connected to the Internet, obtain information about various products and information indicating advertisements from an external device, and display this information on the display means. When information about products displayed on the display means (e.g., a touch panel, etc.) is selected, the operation reception unit 20 may transmit order details for ordering these products to the order reception unit 11 of the control unit 10 via the transmission means.

For example, in the operation reception unit 20, under the control of the control means, regular buttons (which can be customized by the user and correspond to pre-set products (e.g., eggs, milk, pork, beer, mayonnaise, soy sauce, sugar, flour, toilet paper, etc.)) may be displayed on the display means, and when the user operates the regular button, the order details for ordering the product associated with the regular button may be transmitted to the order reception unit 11 of the control unit 10 by the transmission means.

In addition, the operation reception unit 20 may obtain price information indicating the prices of products at multiple stores (e.g., online supermarkets with which the operation unit has an affiliated contract) from an external device under the control of the control means, and display buttons for accessing the stores, for example, in a ranking format in order of lowest price, on the display means. When a button is operated by a user, the order details for ordering a product from the store associated with the button may be transmitted to the order reception unit 11 of the control unit 10 by the transmission means.

The operation reception unit 20 may also store in the storage means a menu table in which menus are associated with products (e.g., food, etc.) required to realize the menu. This menu table may further associate each menu with the amount required to realize the menu, the amount of nutrients when the menu is consumed, etc.

The operation reception unit 20, under the control of the control means, may refer to the menu table, extract a menu item according to the total amount specified by the user, display the extracted menu item on the display means, and, when the menu item is selected by the user, transmit the order details for ordering the product associated with the menu item to the order reception unit 11 of the control unit 10 via the transmission means.

The operation reception unit 20 may also, under the control of the control means, refer to the menu table, extract a menu containing the amount of nutrients according to the results of the health check input by the user, display the extracted menu on the display means, and, when the menu is selected by the user, transmit order details for ordering a product associated with the menu to the order reception unit 11 of the control unit 10 via the transmission means.

The operation reception unit 20 may be a standalone device or a function of various home appliances (e.g., a refrigerator, etc.). The operation reception unit 20 may be attached to the storage unit 2 or may be integrated with the weighing unit 30.

By providing such an operation reception unit 20, products can be ordered simply by operating the buttons on the operation reception unit 20, which contributes to preventing forgetting to buy products, assisting people who have difficulty shopping, and reducing the time spent shopping. In addition, in the event of a viral pandemic, it will be possible to prevent infection during shopping and face-to-face deliveries. Furthermore, when a viral infection spreads, it is expected that infections in hospitals and during shopping and face-to-face deliveries will decrease, slowing the overall spread of infection, which will also lead to a reduction in the overall number of deaths from infection until a vaccine or medicine can be developed.

FIG. 6 is a diagram illustrating the external configuration of the measuring unit according to the embodiment of the present invention.
The weighing unit 30 has an object to be contained placed thereon and generates weighing information indicating the weight of the object to be contained L. Specifically, the weighing unit 30 includes a placement unit 301 on which the object to be contained L is placed, and a weighing unit 302 that generates weighing information indicating the weight of the object to be contained L placed on the placement unit 301.

In the example shown in FIG. 6, the loading section 301 is formed in a box shape with an open top, but it can be formed in any shape, such as a plate shape or a ball shape, as long as the contents can be placed thereon.

The weighing unit 302 includes a weight sensor (pressure sensor) that detects the weight of the contained object L placed on the placement unit 301, a control means that generates weighing information indicating the weight of the contained object L based on the signal detected by the weight sensor, and a transmission means that transmits the weighing information to the control unit 10 via wired or wireless communication.

7 and 8 are diagrams illustrating a usage mode of the measuring unit according to the embodiment of the present invention.
The weighing unit 30 is disposed, for example, in a refrigerator as shown in FIG. 7, but may be disposed anywhere, such as in a food shelf or within the storage space S of the storage unit 2.

As shown in FIG. 8, the weighing unit 30 weighs the weight of the contained object L placed on the placement unit 301 using the weighing unit 302. Then, the weighing unit 302 generates weighing information when, for example, the weighed weight of the contained object L becomes equal to or less than a weight preset by the user, and transmits the weighing information to the control unit 10.

In addition, the weighing unit 30 of the delivery box 1 may detect the weight of the contained item L at a predetermined interval (e.g., once a day) and transmit the weighing information, and the order reception unit 11 of the control unit 10 may generate order information indicating the order details for the contained item L when the weight indicated by the weighing information falls below a weight preset by the user.

The weighing unit 30 may also have identification information for identifying each individual item. The order receiving unit 11 of the control unit 10 may store in a storage means a weighing unit table that associates this identification information with the ordered item. In this case, the weighing unit 30 transmits the identification information and the weighing information to the order receiving unit 11. The order receiving unit 11 may then refer to the weighing unit table and generate order information indicating the order details of the item (contained item L) associated with the received identification information based on the identification information and the weighing information.

The functional configuration of the control unit 10, the operation reception unit 20, and the weighing unit 30 described above is merely an example, and one functional block (database and functional processing unit) may be divided, or multiple functional blocks may be combined into one functional block. Each functional processing unit is realized by a computer program executed by a CPU (Central Processing Unit) built into each device, which reads a computer program (e.g., a core software or an application that causes the CPU to execute the above-mentioned various processes) stored in a storage device (storage means) such as a ROM (Read Only Memory), a flash memory, an SSD (Solid State Drive), or a hard disk. That is, each functional processing unit is realized by the computer program reading and writing necessary data such as a table from a database (DB; Data Base) stored in the storage device or a storage area on the memory, and in some cases controlling related hardware (e.g., an input/output device, a display device, a communication interface device). In addition, the database (DB) in the embodiment of the present invention may be a commercial database, but it also means a simple collection of tables and files, and the internal structure of the database itself is not important.

Such a delivery box 1 has the following advantages.
According to the delivery box 1, the opening 21 of the storage section 2 is open toward the top, so that the stored item L unloaded from a delivery device 150 (e.g., a flying drone) hovering in the sky can be stored in the storage space S of the storage section 2 through the opening 21.
Therefore, it is possible to provide a delivery box that enables delivery by drone even if the delivery destination has limited space.

In addition, by opening the opening 21 of the storage section 2 upward, the number of components in the various sensors and drive mechanisms can be reduced compared to a configuration in which a receiving plate is extended to receive packages from drones, making it possible to provide an inexpensive drone-compatible delivery box. Also, while the weight of packages that can be received is relatively limited when the receiving plate is extended, the delivery box 1 allows packages to be received directly by the storage section 2, reducing the possibility of mechanical failure.

Furthermore, according to the delivery box 1, the storage section 2 forms the storage space S with an exterior material having thermal insulation properties, and can be equipped with a cooling device.
This makes it possible to reduce the number of deaths from a possible future pandemic and respond to super-aging regions in drone-compatible food delivery and medicine delivery to refrigerated and frozen stores. In particular, in areas where there is a labor shortage even at all times, the delivery box 1 with a freezing and refrigeration function is likely to be useful for medicine delivery by drone. In addition, the delivery box 1 with a freezing and refrigeration function is very suitable for delivering refrigerated medicine when the user is absent or when it is difficult to meet the user due to illness. In addition, the delivery box 1 with a freezing and refrigeration function can be used as a second refrigeration or freezer, and is suitable for stocking up, improving the quality of life. In addition, in current home delivery, products that require freezing and refrigeration often need to be handed over in person, and when the user is absent, it is often handled by the delivery company's absence slip. In addition, the delivery box 1 with a freezing and refrigeration function can store products that require freezing and refrigeration, so the effort of redelivery by the delivery company can be reduced, and the labor costs, gasoline costs, and communication costs for redelivery can all be environmentally friendly. In addition, according to the delivery box 1 having a freezing and refrigeration function, even if a user orders a product that needs to be frozen and refrigerated, there is no need to set a time to receive the product, and the user's schedule is not restricted by the time to receive the product.

In addition, according to the delivery box 1, the storage section 2 is provided on both the inside and outside of the exterior wall of the building B.
This eliminates the need for the user to go outside the house to carry the delivered item inside, so the user is not affected by rainy or snowy days, and the burden on the user can be reduced when the user is sick and unable to move. Also, by installing the box on both the inside and outside of the exterior wall of the building B, it becomes possible to supply power from inside the room to operate the delivery box 1 electrically, improving safety compared to when the power source is installed outside.

In addition, the delivery box 1 is provided with a drawer 32 that can be opened and closed through an opening 21 provided on the inside of the building B and can be inserted and removed from the storage space S.
This allows it to be used in factories, etc. For example, the lower part of the drawer 32 can be configured with a conveyor belt, and luggage and materials from the storage space S can be carried indoors by the conveyor belt and then moved to a mail storage area. With such a configuration, luggage can be received even on days when the factory is closed, when there is no one there, or at night, making it possible to smoothly deliver luggage and alleviate labor shortages.

Furthermore, according to delivery box 1, a user can perform operations on the delivery box to order items to be contained from the order reception server, and the ordered items can be received by the delivery box.
This allows ordering and receiving of items to be completed using only the delivery box, improving usability by simplifying the equipment and procedures compared to, for example, ordering using other devices (such as a smartphone or personal computer).

Furthermore, according to the delivery box 1, an order for an item to be contained can be made to the order reception server based on the weight of the item generated by the weighing section, and the ordered item can be received by the delivery box.
This improves usability, because, for example, when an item placed on the weighing section is used and falls below a preset weight, the item can be automatically ordered and received.

Although the present invention has been described above using embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be clear to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, it is clear from the claims that forms incorporating such modifications or improvements can also be included in the technical scope of the present invention.
