The lock/unlock system 10 includes a delivery box 12, a mobile terminal 70, and a management server 80. The delivery box 12 is used in general households, etc., and is capable of receiving delivery packages unattended. The delivery box 12 is used to deliver the package by locking the door 16 after the package is delivered by a delivery company.

The delivery box 12 includes a box main body 13 that is a substantially rectangular parallelepiped exterior, a luggage compartment 14 provided inside the box main body 13, a door 16 that opens and closes an opening 15 of the luggage compartment 14, and a door 16 that can be locked and unlocked. An electronic lock 20 is provided. The luggage compartment 14 has a substantially rectangular parallelepiped box shape that accommodates luggage (not shown) in a removable manner.

The door 16 closes an opening 15 on the front side F of the luggage compartment 14. The door 16 is a single-opening type that is attached to the delivery box 12, and can open and close the opening 15 of the luggage compartment 14 by swinging around a vertical axis (not shown) at the right R end. . The door 16 can be opened by grasping and pulling the case 21 of the electronic lock 20 fixed to the door 16 when the lock portion 35 (FIG. 3) of the electronic lock 20 is in an unlocked state.

The mobile terminal 70 is carried by the user who is the recipient of the package. The mobile terminal 70 is a smartphone, a tablet terminal, or the like. When taking out the package, the user uses the mobile terminal 70 to communicate with the communication unit 33 (FIG. 3) of the electronic lock 20 of the delivery box 12 and unlock the electronic lock 20. The management server 80 communicates with the mobile terminal 70 and performs user authentication and the like.

The electronic lock 20 will be explained in detail below using FIGS. 2 to 4. FIG. 2 is a view of the electronic lock 20 taken out from the delivery box 12 and viewed from the front side F of the door. FIG. 3 is a block diagram showing the configuration of the electronic lock 20.

The electronic lock 20 is attached to the door 16 and allows the door 16 to be electrically locked and unlocked. Specifically, the electronic lock 20 has a case 21 formed of resin or metal, an unlocking code input unit 31, a power supply unit 34, a lock unit 35, an open button 38, a delivery button 39, a first lighting unit 40, a second lighting unit 41, a door sensor 42, and a control device 43.

The case 21 includes a case body 22 that accommodates a plurality of components, and a front plate portion 23 that is fixed to the case body 22 so as to close an opening at the front F end of the case body 22. The front plate portion 23 has a substantially rectangular plate shape that is long in the vertical direction. A substantially rectangular parallelepiped-shaped protrusion 24 that is elongated in the vertical direction is formed in the center of the front plate portion 23 so as to bulge toward the front side F. The front side F end of the protrusion 24 is exposed to the front side F of the door 16 through a rectangular opening 17 formed at the left L end of the door 16. A numeric keypad operation section 32, an open button 38, a delivery button 39, a first lighting section 40, and a second lighting section 41, which will be described later, are exposed on the front side F through a plurality of holes in the protrusion 24. As a result, the numeric keypad operation section 32, the open button 38, the delivery button 39, the first lighting section 40, and the second lighting section 41 are installed on the outside of the door 16.

The case body 22 accommodates a communication section 33, a power supply section 34, a lock section 35, a door sensor 42, and a control device 43 shown in FIG. A latch bolt 36, which will be described later and which forms the lock portion 35, is capable of protruding outward from a side wall (not shown) at the left L end of the case body 22 and retracting into the case body 22. The door sensor 42 is also capable of protruding outward from the side wall at the left L end of the case body 22 and retracting into the case body 22.

3, the unlocking code input unit 31 has a numeric keypad operation unit 32 and a communication unit 33. The numeric keypad operation unit 32 is installed on the outside of the door 16 and has a number of buttons 32a that can be pressed. Information indicating that the button 32a has been pressed is output to the control device 43 (FIG. 3). The communication unit 33 is capable of communicating with a mobile terminal 70 carried by a user who receives a package from the delivery box 12. As a result, the communication unit 33 receives a signal transmitted from the mobile terminal 70 by operating the mobile terminal 70, and outputs the received signal to the control device 43. As described below, when the door 16 is closed and the lock unit 35 is locked in the second locking state by pressing the delivery button 39 described below, the lock unit 35 is unlocked by inputting an unlocking code to the unlocking code input unit 31.

The power supply section 34 includes a battery, and supplies power to the control device 43 and a motor 37a (FIG. 4) that constitutes a bolt drive section 37, which will be described later.

Figure 4 is a schematic diagram showing the latch bolt 36 and bolt driver 37 of the electronic lock 20 and the latch receiver 13a provided on the box body 13 when the door 16 is locked. The lock section 35 of the electronic lock 20 has the latch bolt 36 and the bolt driver 37, and has the function of keeping the door 16 closed. The latch bolt 36 is biased by a spring 35a in a direction that protrudes outward from the side wall of the left side L of the case 21 (Figure 2). The bolt driver 37 has a motor 37a, a first gear 37b fixed to the motor shaft of the motor 37a, a second gear 37c meshing with the first gear 37b, and a lever 37d fixed to the second gear 37c.

A lever 37d is engaged with the inner end of the latch bolt 36. The power of the motor 37a is transmitted to the lever 37d via the first gear 37b and the second gear 37c, and the latch bolt 36 can be moved in the projecting direction or the retracting direction. The motor 37a is controlled by a control device 43. When the motor 37a is driven in the forward direction (direction of arrow A in FIG. 4) by power supply to the motor 37a, the second gear 37c rotates in one direction (direction of arrow B in FIG. 4), causing the lever 37d to rotate. The engaged latch bolt 36 resists the biasing force of the spring 35a and retreats to the inside of the case 21 (FIG. 2). At this time, even if the lock part 35 is unlocked and the door 16 is closed, the latch bolt 36 is retracted from the latch receiving part 13a provided in the part of the box body 13 facing the left L end of the door 16. Therefore, the door 16 can be opened and closed.

On the other hand, after the motor 37a is driven in the opposite direction by power supply to the motor 37a, when the drive of the motor 37a is stopped due to the power supply being stopped, the latch bolt 36 is moved by the biasing force of the spring 35a to the case 21 (Fig. 2) Projects outward. When the door 16 is closed in this state, the latch bolt 36 enters the latch receiving part 13a and this state is maintained, so the lock part 35 is locked and the door 16 cannot be opened. Note that the configuration of the lock portion 35 is not limited to the configuration shown in FIG. 4, and various configurations can be adopted.

On the open button 38, for example, the words "open" are displayed. After the lock unit 35 has been unlocked by inputting an unlock code into the unlock code input unit 31 and after the door 16 has been opened and closed, that is, the door 16 has been opened and then the door 16 has been closed. Later, when the control device 43 locks the lock portion 35 in the first locked state, the control device 43 unlocks the lock portion 35 by pressing the open button 38. In the "first locked state", the control device 43 unlocks the lock unit 35 when the open button 38 is pressed without inputting an unlock code to the unlock code input unit 31. As a result, the lock portion 35 is unlocked by pressing the open button 38, so that the door 16 can be opened freely without being limited to a specific user who can input the unlock code.

The delivery button 39 displays, for example, the words "delivery". After the delivery agent presses the open button 38 to unlock the lock 35 and then stores the package in the baggage compartment 14 and closes the door 16, the control device 43 controls the delivery button 39 to be pressed. , locks the lock portion 35 in the second locked state. In the “second locked state”, the control device 43 unlocks the lock unit 35 only when an unlock code is input to the unlock code input unit 31. Thereby, unlocking of the lock unit 35 can be limited to a specific user who can input the unlock code.

The first lighting unit 40 and the second lighting unit 41 are configured to include a light source such as a light emitting diode (LED). The first lighting unit 40 can change the color when lit. For example, each first lighting unit 40 can be lit in either green or red. The lighting state of each lighting unit 40, 41 is controlled by a control unit 43. Although not shown, an audio output unit is disposed within the case 21, and the operation of the audio output unit is controlled by the control unit 43.

The door sensor 42 has a pressing part 42a (FIG. 2) that is urged to protrude outside the case 21 by, for example, a spring, and when the door 16 is closed, the pressing part 42a is pressed by a portion fixed to the box body 13. However, when the contact is pushed so that its protrusion becomes smaller, the contact closes and turns on. On the other hand, in the door sensor 42, when the door 16 is in an open state, the pressing part 42a is not pressed and the amount of protrusion thereof increases, so that the contact opens and is turned off. Thereby, the door sensor 42 detects the open/closed state of the door 16 based on the on/off state. The detection signal of the door sensor 42 is output to the control device 43.

The control device 43 includes an arithmetic processing unit, which is constituted by, for example, an MCU (Micro Controller Unit), and a storage unit. The storage unit may be a RAM, a ROM, or the like. The arithmetic processing unit has a function of reading and executing programs and the like pre-stored in the storage unit. The storage unit has a function of temporarily storing read programs and processing data, and a function of pre-storing control programs, predetermined thresholds, and the like.

The control device 43 executes a program to realize the main function of the device, system, or method of the present disclosure. The type of the arithmetic processing unit is not important as long as it can realize the function by executing the program. For example, the arithmetic processing unit may be a CPU. The arithmetic processing unit may be composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (large scale integration). The multiple electronic circuits may be integrated into one chip or may be provided on multiple chips. The multiple chips may be integrated into one device or may be provided on multiple devices. A non-transitory recording medium such as an optical disk or a hard disk drive may be used as the storage unit. An external storage device may be connected to the control device 43 as the storage unit. The program may be stored in advance in the recording medium or may be supplied to the recording medium via a wide area communication network including the Internet.

The control device 43 controls the door 16 to be able to open and close when the lock 35 is unlocked by inputting an unlock code to the unlock code input unit 31. The unlock code may be input using the mobile terminal 70 or the numeric keypad operation unit 32. Furthermore, after the lock 35 is unlocked by inputting the unlock code, and the door 16 is opened and closed, i.e., after the door 16 is opened and then closed, the control device 43 controls the lock 35 to be locked in the first locking state. At this time, the control device 43 determines the open state of the door 16 using the detection signal of the door sensor 42.

Furthermore, when the delivery button 39 is pressed while the door 16 is closed, the control device 43 controls the lock unit 35 to lock in the second locking state.

The delivery operation by the delivery company will be described with reference to FIG. 5. FIG. 5 is a sequence chart showing the process or operation of the electronic lock 20 and the delivery company at the time of delivery in the embodiment. FIG. 5 shows a case where the electronic lock 20 is initially locked in the first locking state (S1) and the door 16 is closed. In this case, when the delivery company performs the unlocking operation by pressing the open button 38 (S2), the control device 43 controls the audio output unit and the first lighting unit 40 to notify the user that the door can be unlocked by audio and lighting. For example, the audio output unit outputs a "beep" sound and the first lighting unit 40 lights up in green. On the other hand, if the electronic lock 20 cannot be unlocked due to a malfunction or the like, the audio output unit outputs a "beep" sound and the first lighting unit 40 lights up in red. In FIGS. 5 to 7, the first lighting unit 40 is indicated as "LED1". Furthermore, as an unlocking control, the control device 43 drives the motor 37a in the forward direction (S3), links the motor 37a with the gears 37b and 37c (open state) (S4), retracts the latch bolt 36 into the case 21 (S5), and unlocks the lock 35 (S6). At this time, the control device 43 controls the audio output unit and the first lighting unit 40 to notify the user that the lock has been unlocked by audio and lighting. For example, the audio output unit outputs a "beep beep" sound and the first lighting unit 40 lights up in red.

After the lock 35 is unlocked, the delivery person can open the door 16 by grabbing and pulling the exposed part of the case 21 of the electronic lock 20 on the front side of the door 16 (S7). In this way, in the first locking state, the delivery person can unlock the lock 35 and open the door 16 by pressing the open button 38 without inputting the unlocking code to the unlocking code input unit 31. Then, when the control device 43 determines that the door 16 is open because the door sensor 42 is off (S8), it drives the motor 37a in the reverse direction (S9) to project the latch bolt 36 outside the case 21, and then stops the motor 37a to stop the interlocking between the motor 37a and each gear 37b, 37c (to the closed state) (S10). In this state, the latch bolt 36 is in a state of projecting from the case 21 due to the biasing force of the spring 35a. This causes the control device 43 to prepare for the first locking state.

After the courier puts the package into the baggage compartment 14, the door 16 is closed (S11). At this time, the latch bolt 36 protrudes from the case 21, but by approaching the latch receiving part 13a in the direction of the arrow α in FIG. While being pushed by the latch receiving portion 13a, the latch receiving portion 13a is held. As a result, the control device 43 locks the lock portion 35 in the first locked state and determines that the door 16 is closed due to the door sensor 42 being turned on (S12, S13). In this state, the latch bolt 36 is locked to the latch receiving portion 13a and cannot be moved in the direction opposite to the direction of the arrow α in FIG. 4, so the first locked state is maintained. In this first locked state, it is still possible to unlock the lock portion 35 by pressing the open button 38. Therefore, even if the door 16 accidentally closes due to wind or the like after the delivery company opens the door 16 and before putting the package into the baggage compartment 14, by pressing the open button 38 again, the unlock code input section 31 The lock part 35 can be unlocked and the door 16 can be opened without inputting an unlock code to the door.

Then, when the delivery company presses the delivery button 39 with the door 16 closed (S14), the control device 43 locks the lock part 35 in the second locked state (S15). At this time, the control device 43 controls the sound output section and the first lighting section 40 to notify the transition to the second locked state by sound and lighting. For example, the audio output section outputs the sound "pi" and the first lighting section 40 lights up in red. In the second locked state, the lock section 35 is unlocked only when an unlock code is input to the unlock code input section 31. When the open button 38 is pressed in the second locked state (S16), the control device 43 controls the audio output section and the first lighting section 40 to notify by sound and lighting that the lock cannot be unlocked. For example, the audio output section outputs a "pi-pi" sound, and the first lighting section 40 lights up in red.

Next, the baggage removal operation will be explained using FIG. 6. FIG. 6 is a sequence chart showing the processing or operation of the electronic lock 20, the delivery company, the user, the mobile terminal 70, and the management server 80 during the baggage removal operation in the embodiment. In the example of FIG. 6, the user performs an operation to unlock the electronic lock 20 using the mobile terminal 70. Specifically, first, the electronic lock 20 is locked in the second locked state and is in the receiving state (S20). In this case, as shown in FIG. 5, even if the open button 38 is pressed, the lock part 35 is not unlocked, and the control device 43 uses the audio output part and the first lighting part to indicate that the lock cannot be unlocked. 40 sound and lighting. On the other hand, the user performs a connection operation using the mobile terminal 70 to perform Bluetooth (registered trademark) wireless communication with the communication unit 33 of the electronic lock 20 (S21, S22). At this time, for example, the mobile terminal 70 and the communication unit 33 perform a connection operation for BLE (Bluetooth (registered trademark) Low Energy) wireless communication. Then, when the wireless connection is established, the control device 43 controls the second lighting unit 41 to notify this fact. For example, the second lighting section 41 lights up in green. In FIGS. 6 and 7, the second lighting section 41 is shown as "LED2". At this time, the audio output section does not output sound. Then, the user starts an application program for a retrieval operation on the mobile terminal 70 (S23). When this program is executed, the user's preset authentication code is transmitted to the management server 80 (S24), and the management server 80 and the mobile terminal 70 are linked together (S25). At this time, the management server 80 authenticates the user when the received authentication code matches the authentication code stored in the management server 80, and sends information on the completion of receiving the goods associated with the authentication code to the mobile terminal 70. Send. When the mobile terminal 70 receives the information that the receipt is completed from the management server 80, the application program transmits the unlock code as a release communication to the communication unit 33 of the electronic lock 20 by wireless communication using Bluetooth (registered trademark). S26, S27). At this time, if the unlock code input to the communication unit 33 matches the unlock code stored in the control device 43 of the electronic lock 20, the control device 43 determines that an unlock instruction has been given (S28). , controls the audio output section and the first lighting section 40. For example, the audio output section outputs the sound "pi" and the first lighting section 40 lights up in green. At this time, the second lighting section 41 remains lit in green. On the other hand, if the unlock code transmitted from the mobile terminal 70 does not match the unlock code stored in the control device 43, the control device 43 determines that an unlock instruction has not been given, and the voice output unit and controls the first lighting section 40. For example, the audio output section outputs a "pi-pi" sound, and the first lighting section 40 lights up in red.

When the control device 43 determines that an unlocking command has been issued, the control device 43 performs unlocking control similar to the processes of (S3) to (S6) in FIG. 5, as processes (S29) to (S32) in FIG. 6, to unlock the lock unit 35. When the lock unit 35 is unlocked, the control device 43 controls the audio output unit and the first lighting unit 40. For example, the audio output unit outputs a "beep beep beep" sound, and the first lighting unit 40 lights up in red.

This allows the user to open the door 16 (S33) and take out the luggage. Due to the opening of the door 16, the control device 43 determines that the door sensor 42 is turned off (S34), similarly to the processes from (S8) to (S10) in FIG. 5, and drives the motor 37a in the opposite direction ( After S35), the motor 37a is stopped, and the interlocking between the motor 37a and each gear 37b and 37c is stopped (closed) (S36). In this state, the latch bolt 36 protrudes from the case 21 due to the urging force of the spring 35a. Thereby, the control device 43 prepares for the first locked state.

When the user closes the door 16 (S37) and the control device 43 determines that the door sensor 42 is turned on (S38), it locks the lock part 35 in the first locked state (S39). In this case, the lock portion 35 can be unlocked by simply pressing the open button 38 similarly to step S16 in FIG.

FIG. 7 is a sequence chart showing processing or operations performed by the electronic lock 20, the delivery company, and the user during another example of a baggage removal operation in the embodiment. In the example of FIG. 7, the user performs an operation to unlock the electronic lock 20 using the numeric keypad operation section 32. Specifically, first, the electronic lock 20 is locked in the second locked state and is in the receiving state (S40). In this case, even if the open button 38 is pressed, the lock part 35 is not unlocked, and the control device 43 notifies the user that the lock cannot be unlocked by the sound output part and the first lighting part 40 and the lighting state. . On the other hand, the user inputs an unlock code into the electronic lock 20 using the numeric keypad operation section 32 (S41, S42). For example, the user presses the enter button 32b (FIG. 2) after inputting the unlock code number using the numeric keypad operation section 32. If the unlock code entered using the numeric keypad operation unit 32 matches the unlock code stored in the control device 43 of the electronic lock 20, the control device 43 determines that an unlock instruction has been given (S43), and outputs a voice message. The output section and the first lighting section 40 are controlled. For example, the audio output section outputs the sound "pi" and the first lighting section 40 lights up in green. On the other hand, if the unlock code input using the numeric keypad operation unit 32 does not match the unlock code stored in the control device 43 of the electronic lock 20, the control device 43 determines that an unlock instruction has not been given. and controls the audio output section and the first lighting section 40. For example, the audio output section outputs a "pi-pi" sound, and the first lighting section 40 lights up in red.

If the control device 43 determines that a release instruction has been given, the control device 43 performs the same steps as the steps (S3) to (S6) in FIG. 5 as the steps (S44) to (S47) in FIG. The unlocking control is performed to unlock the lock portion 35. When the lock section 35 is unlocked, the control device 43 controls the audio output section and the first lighting section 40. For example, the audio output section outputs a "pi-pi-pi" sound, and the first lighting section 40 lights up in red.

This allows the user to open the door 16 (S48) and remove the luggage. As a result of this opening of the door 16, the control device 43 determines that the door sensor 42 has been turned off (S49), similar to the processes (S8) to (S10) in FIG. 5, and drives the motor 37a in the reverse direction (S50), and then stops the motor 37a and stops the linkage between the motor 37a and each of the gears 37b and 37c (setting the door in the closed state) (S51). In this state, the latch bolt 36 is protruding from the case 21 due to the biasing force of the spring 35a. This causes the control device 43 to prepare for the first locking state.

Then, when the user closes the door 16 (S52) and the control device 43 determines that the door sensor 42 is turned on (S53), it locks the lock part 35 in the first locked state (S54). In this case, the lock portion 35 can be unlocked by simply pressing the open button 38 similarly to step S16 in FIG.

According to the locking/unlocking system 10 for the delivery box 12 of this example, the burden on the delivery company when depositing the parcel in the delivery box 12 can be reduced, and the parcel can be stored safely. For example, even if the delivery person of the delivery company does not have an input device for an unlocking code such as a mobile terminal 70, the parcel can be easily delivered to the delivery box 12. In addition, there is no need to limit the delivery companies that can deliver parcels to specific companies that have an input device. Furthermore, even if the door 16 is accidentally closed due to wind or some other reason after the delivery company opens it, the door can be easily opened by simply pressing the open button 38. This reduces the burden on the delivery company when depositing the parcel. Furthermore, after the delivery company presses the delivery button 39, the door 16 can be unlocked only by specific users who can input the unlocking code, so the parcel can be stored safely.

The unlocking code input unit 31 also includes both a numeric keypad operation unit 32 installed on the outside of the door 16, and a communication unit 33 that receives a signal transmitted from the mobile terminal 70 by operating the mobile terminal 70. This allows the user to select either the numeric keypad operation unit 32 or the mobile terminal 70 according to the user's preference, etc., and use it to unlock the electronic lock 20.

The unlocking code input unit 31 may be configured to include only one of the numeric keypad operation unit 32 and the communication unit 33. If the unlocking code input unit 31 includes only the communication unit 33 out of the numeric keypad operation unit 32 and the communication unit 33, the numeric keypad operation unit 32 can be omitted from the door 16, thereby improving the design of the exterior of the door 16.

In the above embodiment, the door sensor 42 is integrally provided in the case 21 of the electronic lock 20. However, the present disclosure is not limited to this, and the door sensor 42 may be provided in a part other than the case 21 of the electronic lock 20 so as to be able to detect the opening and closing of the door 16, and the detection signal of the door sensor 42 may be transmitted to the control device 43 of the electronic lock 20 via a signal line or the like.
