Hereinafter, an example of an embodiment in which the present invention is applied to, for example, an electronic key storage device capable of easily realizing a car sharing system at low cost will be described. The electronic key is an electronic key that is unique to one vehicle shared by a plurality of users who are drivers, and its shape, structure, and size vary depending on the vehicle type of the vehicle. It is assumed that the existing electronic key has an unlock button for unlocking the unlocked vehicle door in a non-contact manner and a lock button for unlocking the unlocked vehicle door in a non-contact manner.

[First Embodiment]
FIG. 1 is a block configuration diagram of an electronic key storage device 1 according to the first embodiment. This electronic key storage device 1 includes a holding mechanism 11, a communication module 12, an unlocking button 21, and a locking button that detachably holds an electronic key 20 having an unlocking button 21 and a locking button 22 in a portable housing 10. The power supply circuit 14 and the pressing mechanism 13 that selectively presses 22 and 22 are housed. The power supply circuit 14 is a DC electric circuit including a replaceable button battery, but may be a circuit electrically connected to a vehicle battery.
The electronic key storage device 1 can be used by being placed in an arbitrary place of a vehicle, for example, an inner pocket of a vehicle door, a rear pocket of a driver's seat or a passenger seat, a dashboard, and the like.

The communication module 12 operates by being supplied with power from the power supply circuit 14, and enables short-range communication with the portable information terminal 50. In the present embodiment, the frequency is 2.4 GHz band, the data rate is 10 kb/s, and the Bluetooth (registered trademark) module with built-in antenna (IEEE802.15.1) is used to perform Bluetooth communication with the portable information terminal 50. To do.
Bluetooth communication is possible only in the coverage area of several meters centering on the built-in antenna of the Bluetooth module. Therefore, there is an advantage that security is maintained as compared with a large-capacity wireless communication having a wide coverage area. Note that, instead of the Bluetooth module, an NFC module or the like that can communicate with an NFC (Near field communication) module that is standardly equipped in recent mobile terminals and the like may be used.

The pressing mechanism 13 selectively presses the unlock button 21 or the lock button 22 of the electronic key 20 each time the communication module receives a predetermined signal, and then autonomously returns to the state before pressing. Is a set of. Specifically, the pressing mechanism 13 includes the first solenoid 131 and the second solenoid 132 that move up and down with respect to the fixed position of the electronic key 20, and the control circuit 133. A displacement mechanism such as the receptacle 134 may be included in the pressing mechanism 13.
The first solenoid 131 and the second solenoid 132 are components each having a displacement body that converts an input electric signal into a physical motion. Specific configuration examples of the first solenoid 131 and the second solenoid 132 will be described in detail later.

The receptacle 134 is an example of a displacement mechanism for fixing the installation positions of the first solenoid 131 and the second solenoid 132 in a freely changeable manner, and may be integrally formed when the base portion 101 is formed. In the illustrated example, the receptacle 134 is formed in an L shape along the long side and the short side of the base portion 101, but the I shape along one long side or one short side and two sides. It may be formed in a U-shape along two long sides.

FIG. 2 is a structural explanatory view of the portable housing 10. In the following description, for convenience, the three-dimensional XYZ X direction is the forward direction (length), the Y direction (width) is the lateral direction (width), and the +Z direction of the Z direction (height) is the upward direction and the −Z direction. May be called downward. The portable housing 10 is composed of a set of a palm-sized base portion 101 formed of hard plastic, which is an example of a radio wave transmitting member, and a cover portion 102 that seals the opening of the base portion 101. ..
The base portion 101 has a two-stage structure, and of a pair of side surface portions extending from the lower bottom portion 101a and facing each other in the Y direction, an engaging portion 101c for fixing the peripheral portion of the upper bottom portion 101b to a portion having a constant height. Are formed. The communication module 12, the first solenoid 131, the second solenoid 132, the control circuit 133, the receptacle 134, and the power supply circuit 14 are mounted in the lower storage space partitioned by the lower bottom portion 101a and the upper bottom portion 101b.
The upper bottom part 101b is a flat plate in which the movable range of the first solenoid 131 and the second solenoid 132 is cut out, and the remaining parts are in the upper storage space formed by the opening of the base part 101 and the upper bottom part 101b. Will be implemented.

The edge portion of the base portion 101 is joined to the outer edge portion of the cover portion 102. A hinge 101d is provided on one end surface portion of the pair of end surface portions of the base portion 101 facing each other in the X direction. Further, a hinge 102d is provided at an end portion of the pair of end portions of the cover portion 102 facing each other in the X direction, which is close to the hinge 101d. The hinge 101d and the hinge 102d are engaged with each other by a hinge shaft (not shown), and the cover portion 102 is rotatable about the hinge shaft. This makes it easy to seal the component storage space of the base portion 101 with the cover portion 102 or to expose the base portion 101 to install or replace components.

It should be noted that the reason that only one end surface portion of the base portion 101 is cut off is a device for facilitating the insertion/removal of the fitting holder 111, which will be described later, by sliding in the X direction through the end surface portion. .. However, when the fitting holder 111 is taken in and out infrequently, the fitting holder 111 may be taken in and out through the opening of the base portion 101, and such a device is not necessarily required. In this case, each of the base portion 101 and the cover portion 102 can be formed in a general box shape, which is advantageous in that the portable housing 10 can be easily mass-produced.

FIG. 3 is a component layout explanatory view of the storage space of the base portion 101 with the cover portion 102 removed, as seen from above, and FIG. 4 is a view of the base portion 101 shown in FIG. Is. For convenience, the components shown in FIGS. 1 and 2 are denoted by the same reference numerals. A fitting holder 111 that holds the electronic key 20 in a detachable manner, and a frame 112 that houses the fitting holder 111 and fixes the fitting holder 111 at a predetermined position are provided in a substantially central portion of the base portion 101.

The fitting holder 111 is an example of a fitting portion for removably fitting the electronic key 20, and is made of an elastic member such as silicone rubber, polyurethane, or polystyrene foam. In this fitting holder 111, one of the substantially rectangular columnar elastic solids or adjacent surface portions (for example, the main surface portion and the short side end portion) are hollowed out along the outer shape (including the thickness) of the electronic key 20. Created.
The size including the thickness of the hollowed hole 111 a is slightly smaller than the outer shape of the electronic key 20. The formation position of the hole 111a is determined according to the installation structure (position etc.) of the holding mechanism 11 described later. Since the fitting holder 111 is made of an elastic member, the electronic key 20 fitted in the hole 111a is held by the elastic force of the hole 111a.

A take-out portion 111b having a size into which the tip of a human finger is inserted is formed on the periphery of any part of the hole 111a of the fitting holder 111. With this take-out portion 111b, the driver can easily remove the electronic key 20 fitted in the fitting holder 111 from the hole 111a. An energizing switch 113 is provided at a predetermined portion of the hole of the fitting holder 111. The energizing switch 113 is, for example, a two-contact switch, and one contact is connected to the power supply circuit 14. The other contact of the energizing switch 113 is connected to the communication module 12 and the pressing mechanism 13. The energizing switch 113 is turned on by the pressing force of the electronic key 20 when the electronic key 20 is held in the fitting holder 111 (an energized state in which the contacts are electrically connected), and the electronic key 20 is removed from the fitting holder 111. When removed, the pressing force is released and the device is turned off (a state in which energization is stopped by disconnecting the contacts).

The electronic key 20 is generally formed in a shape and structure determined for each vehicle or vehicle type, but the overall shape and size is a small size of about several tens of millimeters square. Therefore, by fixing the sizes of the base portion 101 and the frame 112 to the maximum value of the assumed size, creating the fitting holder 111 of a size smaller than that for each electronic key 20, and exchanging it appropriately, The electronic key 20 having any shape and structure can be stored.

Next, the first solenoid 131, the second solenoid 132, the control circuit 133, and the receptacle 134 will be described in detail.
Each of the solenoids 131 and 132 includes a fixed iron core which is a permanent magnet, a movable iron core (plunger) whose one end faces the fixed iron core, a coil in which a copper wire is wound around the plunger in a non-contact manner, and a coil. And a frame that surrounds and fixes the outer surface of the. As these solenoids 131 and 132, DC solenoids that operate with DC power supplied from the power supply circuit 14 via the energizing switch 113 are used, but AC solenoids may be used. However, in this case, the output of the power supply circuit 14 needs to be AC power.

As shown in FIG. 3 and FIG. 4, the receptacle 134 is formed with a recessed groove 134a whose opening is narrower than the hollow portion, and is formed in the frame 1310 of the first solenoid 131 and the frame 1320 of the second solenoid 132. Each has a protrusion (a protrusion 1310a in the example of FIG. 4) slidably engaged with and fixed to the concave groove 134a of the receptacle 134. Thereby, the first solenoid 131 and the second solenoid 132 can independently change their installation positions independently of each other. Therefore, the electronic key 20 having various shapes, structures, and sizes can be easily dealt with.

One end of a connector 1312 is fixed to the tip of the plunger 1311 of the first solenoid 131 with a screw 1312a. At the other end of the connecting tool 1312, an operating tool 1313 that is oriented substantially parallel to the plunger 1311 and points the direction of the unlock button 21 of the electronic key 20 fitted in the fitting holder 111 is fixed by a screw 1313a.
Although not shown in FIG. 4 (shown in FIG. 3 ), one end of the connecting member 1322 is fixed to the tip end portion of the plunger 1312 of the second solenoid 131 by a screw 1322 a. At the other end of the connecting tool 1322, an operating tool 1323 that is oriented substantially parallel to the plunger 1312 and points the lock button 22 of the electronic key 20 fitted in the fitting holder 111 is fixed by a screw 1323a.

In order to freely change the lengths of the connecting members 1312 and 1322, for example, two metal plates of the same size having a plurality of screw holes formed thereon are slid in opposite longitudinal directions in a state of being overlapped with each other. Then, when the desired length is reached, two metal plates may be tightened in the screw holes with bolts and nuts.
By doing so, even if the size of the electronic key 20 and the arrangement of the unlock button 21 and the lock button 22 are different, the electronic key 20 can be stored.

The operating tools 1313, 1323 fixed to the connecting tools 1312, 1322 are made of, for example, soft elastic members formed in the shape of human fingertips. As the elastic member, silicone material, natural rubber, urethane rubber, acrylic rubber, nitrile rubber, hydrin rubber, butyl rubber, styrene butadiene rubber, chloroprene rubber, ethylene propylene rubber, fluororubber and the like can be used. In this embodiment, silicone materials are used as the operation tools 1313 and 1323 for the following reasons.

-Silicone material having a siloxane bond (-Si-O-Si-) as a main skeleton has a helix structure (coil) in molecule, and is more elastic than organic rubber or organic synthetic resin. Further, unlike the material containing carbon, it is chemically inactive, so that it does not corrode the operating tools 1313, 1323 and the like.
・While the sunshine in midsummer is extremely high in the passenger compartment, the silicone, which has a siloxane bond as the main skeleton, has almost no change in properties even after being molded at around 150 degrees Celsius, and can be used semipermanently unless broken.
The embrittlement point of the organic rubber is -20 to -30 degrees Celsius, whereas the embrittlement point of the inorganic silicone having a siloxane bond as the main skeleton is -60 to -70 degrees Celsius, so Maintains elasticity even at temperatures at which various types of elastic materials become brittle, and has excellent low-temperature properties. Therefore, it becomes suitable for long-term use.
-The physical properties of the inorganic silicone, which has a siloxane bond as the main skeleton, are not affected by ozone or ultraviolet rays (organic elastic materials rapidly deteriorate when exposed to ozone or ultraviolet rays). Therefore, it can be used for a long period of time without any maintenance.
-Coloring is easy because it has affinity with pigments and fluorescent substances.

Rubber-based silicone materials have a well-known hardness index. For example, 5 degrees or more and less than 30 degrees measured with a type A durometer (JIS K6253) in the Japan Rubber Association standard (SRIS0101) is "low hardness", 30 degrees or more and less than 50 degrees is "medium hardness", and 50 degrees or more is " It is classified as "high hardness". Low hardness is about the same as human skin, and it is said that about 40 degrees of medium hardness is an eraser, 60 to 70 degrees is a car tire, and 80 degrees is close to a mouse ball hardness. Hardness is determined by the amount of silica powder filler added.

In this embodiment, a silicone material having a hardness of 30 degrees or more and less than 50 degrees is used as the operation tools 1313 and 1323 in order to have a hardness that does not damage the unlocking button 21 and the locking button 22 of the electronic key 20 by pressing. According to the experiments conducted by the present inventors, the silicone material having such a hardness range can ensure the operability, the restoring property, and the durability which are substantially the same as those when the unlocking button 21 or the locking button 22 is pressed with a human finger. It is clear.

The operation tools 1313 and 1323 are stopped at a position farthest from the fitting holder 111 in a state where the energization of the coils of the first solenoid 131 and the second solenoid 132 is stopped (default state). In this state, the fitting holder 111 can be freely replaced with another fitting holder.
On the other hand, when the coil of the first solenoid 131 is energized while the fitting holder 111 is fixed to the frame 112, the plunger 1311 is magnetized by the magnetic force of the coil and attracted to the fixed iron core. As a result, the operation tool 1313 fixed to the tip end portion of the plunger 1311 via the connection tool 1312 presses the unlock button 21 of the electronic key 20 fitted in the fitting holder 111.

Similarly, when the coil of the second solenoid 132 is energized, the plunger 1321 is magnetized by the magnetic force of the coil and attracted to the fixed iron core. As a result, the operation tool 1323 fixed to the tip end portion of the plunger 1321 via the connection tool 1322 presses the lock button 22 of the electronic key 20 fitted in the fitting holder 111.

On the other hand, when the energization of the coils of the solenoids 131 and 132 is stopped, the magnetic force disappears, the plungers 1311 and 1321 are released from the fixed electrode, and autonomously return to the original state. As a result, the operation tools 1313 and 1323 are separated from the unlock button 21 and the lock button 22 of the electronic key 20.

The control circuit 133 is electrically connected to the other end of the energizing switch 113 whose one end is connected to the power supply circuit 14 and the communication module 12, and the state of the energizing switch 113 and the presence/absence of significant signal reception from the communication module 12. Based on the above, the energization and interruption (energization stop) of the coils of the solenoids 131 and 132 are controlled.
Control modes include first to third patterns shown in FIGS. 5A to 5C, and the first control signal and the second control signal selectively transmitted from the portable information terminal 50. One of the patterns is selectively switched based on.

First pattern (FIG. 5A): When the energizing switch 113 is on, the first solenoid 131 and the second solenoid 132 are forcibly deenergized, and the magnetic forces generated in the respective coils are erased. When the energizing switch 113 is off, the control circuit 133 does not operate, but the magnetic field is not generated in the first solenoid 131 and the second solenoid 132, so that the same state occurs.
Second pattern (FIG. 5B): When the energizing switch 113 is on, the coil of the first solenoid 131 is energized for a certain period of time upon reception of the first control signal from the communication module 12, and then the first The energization of the coil of the solenoid 131 is stopped.
-Third pattern (Fig. 5(c)): When the energizing switch 113 is on, the coil of the second solenoid 132 is energized for a certain period of time upon reception of the second control signal from the communication module 12, and then the second The energization of the coil of the solenoid 132 is stopped. The energization time is about 1 second, but it may be another time.

The first control signal is a signal for transmitting the first electric path that connects the control circuit 133 and the coil of the first solenoid 131, and switches from the default disabled state to the enabled (significant signal) in the first circuit, The energization of the coil is allowed only for a certain period of time (for example, about 1 second in which the logic High continues) in which the enabled state continues.
The second control signal is a signal for transmitting a second electric path that connects the control circuit 133 and the coil of the second solenoid 132, and switches from the default disabled state to the enabled (significant signal) in the second circuit. The energization of the coil is allowed only for a certain period of time (for example, about 1 second in which the logic High continues) in which the enabled state continues.

The first pattern is a state in which the first control signal and the second control signal are not significant signals (disabled state). The state in which the first control signal is enabled and the second control signal is disabled is the second pattern. The third pattern is a state in which the second control signal is enabled and the first control signal is disabled. Since the first control signal and the second control signal are both in the disabled state after a fixed time has passed, most of the time remains the third pattern.

The control circuit 133 determines whether the first control signal (first electric path) or the second control signal (second electric path) is a signal ID (for example, a predetermined time) transmitted from the portable information terminal 50 prior to these control signals. It is possible to make a distinction by recognizing the number of pulses or the data identified by the pulse pattern.

Next, the portable information terminal 50 will be described. FIG. 6 is a hardware configuration diagram of the portable information terminal 50. The mobile information terminal 50 is a type of mobile phone having a data processing function, and includes a CPU (Central Processing Unit) 201, a ROM (Read Only Memory) 202, a RAM (Random Access Memory) 203, a storage 204, a communication module 205, and communication. An I/F (Input/Output) 206, an input/output I/F (Input/Output) 207, and a GPS module 208 are provided.

The CPU 201 causes the portable information terminal 50 to operate as a computer by executing the control program stored in the ROM 202 using the RAM 203 as a work area. Since the CPU 201 operates with a clock having a predetermined cycle, the computer has a timer function. The storage 204 is a large-capacity storage device such as an HDD (Hard Disk Drive) or SSD (Solid State Drive). The storage 204 stores an application program (hereinafter, “AP”) downloaded from the network N via the communication I/F 206, various data for AP, a predetermined authentication code used for pairing described later (for example, valid only for a certain period of time). An authentication code such as a one-time password), authority information (for example, ID and password) for accessing a server connected to the network N, and the like are stored.

The network N is, for example, a wide area network such as the Internet, and in the present embodiment, a management server 30 that manages a vehicle use condition or a vacant condition for car sharing by data communication with the portable information terminal 50 is connected. Be present.
The management server 30 includes a vehicle database that records a vehicle usage log in association with a vehicle number. The usage log includes the ID of the user who made the reservation, the date and time of the reservation, the date and time of unlocking/locking the vehicle door, the latest position of the vehicle, and the like. The management server 30 also stores authentication information used for pairing with the electronic key storage device 1 and authority information for permitting access from the portable information terminal 50.

The communication module 205 is a known module that performs Bluetooth communication, which is an example of near field communication, with another communication module, which is the communication module 12 of the electronic key storage device 1 in the present embodiment. The communication I/F 206 performs communication control for bidirectional data communication with the management server 30, for example. The input/output I/F 207 controls input/output with the input device and the output device. The input device is a device that receives input of various instructions from a user through a touch operation on a displayed operation screen, a keyboard operation, or the like, such as a display having a touch panel. The output device is the display (operation screen), speaker, external memory, or the like. The GPS module 208 is a general-purpose module with an antenna that receives GPS data from GPS satellites.

In the portable information terminal 50, the CPU 201 executes the AP stored in the storage 204, for example, the use reservation AP 2041, under the control of the control program (operating system, file system, other utility program, etc.) stored in the ROM 202. , Realizes various functional blocks.

FIG. 7 shows a configuration example of functional blocks realized in the mobile information terminal 50. In the present embodiment, the mobile information terminal 50 includes an input control unit 401, an output control unit 402, a current position detection unit 403, a first communication control unit 404, a second communication control unit 405, an instruction analysis unit 406, and a reservation process execution. An example of functioning as the unit 407 and a main control unit 408 that integrally controls these units is shown.

The input control unit 401 receives various instructions input by the user through the input/output I/F 207. The output control unit 402 outputs an operation screen for the user, a result of data processing performed under the control of the main control unit 408, and the like to a display or the like through the input/output I/F 307. The current position detection unit 403 detects the current position, the current date and time, etc. from the GPS data.

The first communication control unit 404 controls Bluetooth communication performed between the communication module 205 and the communication module 12 included in the electronic key storage device 1 after the use reservation AP 2041 is activated. The first communication control unit 401 performs pairing between the communication module 205 and the communication module 12 prior to Bluetooth communication. For the pairing, on the assumption that the communication module 12 is energized, the authentication code received from the management server 30 is displayed on the display, and the same authentication code as the displayed authentication code is input by the operation of the touch panel. That is what makes it successful. When the pairing is successful, the first communication control unit 401 continues the Bluetooth communication until it receives the communication end instruction, or the pairing is released due to the notification of the power supply stop of the communication module 12 or the like.

When the authentication code is stored in the storage 204 in advance, the pairing can be automatically successful by automatically inputting the authentication code without waiting for the operation of the touch panel. At that time, a token or the like for selectively outputting a plurality of authentication codes is provided, and when the same authentication code as any of the outputable authentication codes is received from the management server 30, the pair is automatically paired. You may make the ring succeed.
Further, even when the use reservation AP 2041 is restarted within a predetermined time after the use reservation AP 2041 is stopped, the pairing may be automatically made successful.

The second communication control unit 405 controls data communication (excluding Bluetooth communication) via the communication I/F 206 and the network N. Prior to this data communication, the second communication control unit 405 compares the authority information stored in the storage 204 with the authority information input by the user. That is, authentication is performed. When the authority information matches, the second communication control unit 405 continues the data communication with the management server 30 until receiving the communication end instruction.

The first communication control unit 401 and the second communication control unit 402 can operate independently. That is, it is possible to perform data communication with the management server 30 while performing Bluetooth communication. It is also possible to perform only Bluetooth communication or only data communication.

The instruction analysis unit 406 analyzes the content of various instructions input from the input control unit 401, and outputs data according to the analysis result. In the present embodiment, authentication data when pairing with the electronic key storage device 1 (when setting is made so that automatic pairing is not performed), authority information when establishing a communication path with the management server 30 and making access. , Instructions for activating and stopping the use reservation AP 2041 (communication path release), data (vehicle number, etc.) requested by the reservation process execution unit 407, the above-mentioned first control signal and second control signal, etc. as one of the analysis results. It shall be output.

The reservation processing execution unit 407 is a function that plays a central role in the usage reservation AP 2041, and under the control of the main control unit 408, cooperates with other functional blocks, the electronic key storage device 1, and the management server 30, and Of the reserved vehicle and use of the reserved vehicle (use of the electronic key 20 dedicated to the vehicle) are performed. The overall procedure of this processing will be specifically described.
Here, for convenience of explanation, the vehicle to be reserved is the vehicle in front of the user who is operating the portable information terminal 50, and the dedicated electronic key 20 is stored with the vehicle door locked. It is assumed that the electronic key storage device 1 is placed in the passenger compartment of the vehicle.

When the use reservation AP 2041 is executed, the reservation processing execution unit 407 uses the AP data stored in the storage 204 to display the initial screen on the operation screen of the display of the portable information terminal 50. FIG. 8A is an exemplary view of an initial screen displayed on the operation screen 500. On the initial screen, an ON image 501 for starting data communication with the management server 30 and an OFF image 502 for ending the data communication are displayed. When the user touch-operates the ON image 501, the second communication control unit 402 establishes a communication path with the management server 30 by the above procedure and starts data communication.

When data communication with the management server 30 becomes possible, the operation screen 500 switches as shown in FIG. 8B. In FIG. 8B, the vehicle number to be used (for example, the last four digits of the license plate) is input to the vehicle number input area 503. Input is performed by touching the ten-key image 504.

When the management server 30 confirms that the vehicle identified by the vehicle number is free and locked by referring to the vehicle database, it newly creates a usage log of the reserved user and stores the usage log in the vehicle. The data is recorded in the database, and the data indicating the use status of the vehicle (the vehicle door is in a locked state, etc.) and the predetermined authentication code are transmitted to the portable information terminal 50. In the portable information terminal 50 that has received the authentication code, the first communication control unit 401 automatically starts pairing with the electronic key storage device 1. When pairing is performed manually, a screen for inputting an authentication code is displayed, and the matching with the input authentication code is determined.

When the pairing is successful, the operation screen 500 is switched as shown in FIG. 8(c). On the operation screen 500 illustrated in FIG. 8C, an unlock image 505 for selecting the unlocking of the vehicle door, a locking image 506 for selecting the locking of the vehicle door, and the initial screen are returned. A button image 507 for is displayed. Since the vehicle door is locked, only the unlocked image 505 that can be selected by the user is highlighted in the illustrated example. The mode of highlighting is a color change, blinking, or the like.

When the unlocking image 505 is touch-operated, the data indicating that the unlocking instruction is input by the instruction analyzing unit 406 is sent to the management server 30 through the second communication control unit 405 together with the vehicle number, the current position, and the current date and time. In addition to transmitting the above-mentioned first control signal, the first control signal is transmitted to the electronic key storage device 1 through the first communication control unit 404.
The management server 30 updates the usage log of the vehicle database based on the received data (records the unlock date and time).
In the electronic key storage device 1, the operation tool 1312 of the first solenoid 131 presses the unlock button 21 of the electronic key 20 upon receiving the first control signal. As a result, the vehicle door is unlocked by the original function of the electronic key 20. When the vehicle door is unlocked, the user can open the vehicle door to enter the vehicle compartment and take out the electronic key 20 from the fitting holder 111 of the electronic key storage device 1.

The user who secures the electronic key 20 can start driving the vehicle using the electronic key 20 or can manually lock/unlock at any time. Therefore, the button image 507 is touched to display the initial screen of FIG. 8A, and the OFF image 502 is touched. Thereby, the data communication with the management server 30 can be ended. At this time, the use reservation AP 2041 may be terminated.

It is assumed that the time required for the user to touch the unlocked image 505 to open the vehicle door and secure the electronic key 20 in the vehicle compartment is less than 3 minutes. When the electronic key 20 is taken out from the electronic key storage device 1, the energizing switch 113 is cut off and the Bluetooth communication is stopped. That is, the pairing is released in the assumed usage mode.
Therefore, the reservation process execution unit 407 forcibly displays the operation screen 500 in FIG. 8A when 3 minutes have elapsed after the unlocked image 505 was touch-operated in the display of the operation screen 500 in FIG. 8C. ) Return to the initial screen. At this time, the reservation process execution unit 407 may forcibly create a state in which the OFF image 502 is touch-operated, and terminate the data communication with the management server 30.

In the display of the operation screen 500 of FIG. 8C, if the pairing is not released within 3 minutes after the touch operation of the unlock image 505, the electronic key 20 is operated by the user even if the vehicle door is unlocked. It is not secured in. Therefore, the reservation process execution unit 407 creates a state in which the locked image 506 is forcibly touched. At this time, the instruction analysis unit 406 causes the second communication control unit 405 to transmit the data indicating that the instruction for the forced lock has been input, together with the vehicle number, the current position, and the current date and time, to the management server 30. Output the second control signal from the electronic key storage device 1 through the first communication control unit 404. The management server 30 updates the usage log of the vehicle database based on the received data (records the locking date and time). In the electronic key storage device 1, the operation tool 1322 of the second solenoid 132 presses the lock button 22 of the electronic key 20 upon receiving the first control signal. As a result, the vehicle door is locked by the original function of the electronic key 20. This maintains security.
The above-mentioned time of 3 minutes is an example, and may be 2 minutes or less than 1 minute, or may be more than 3 minutes. This time may be arbitrarily set by the user.

The user who normally secures the electronic key 20 stores the electronic key 20 in the fitting holder 111 of the electronic key storage device 1 when the operation of the vehicle is completed. As a result, the energizing switch 113 is energized and the electronic key storage device 1 becomes operable. In this state, when the user activates or restarts the use reservation AP 2401 from outside the vehicle compartment, the first communication control unit 404 of the portable information terminal 50 automatically performs pairing with the electronic key storage device 1 and displays it. The operation screen 500 shown in FIG. 8A is displayed on the screen.

When the user touch-operates the ON image 501, authentication and communication channel establishment are performed with the management server 30 in the same procedure as described above, and the operation screen 500 is switched as shown in FIG. 8B. When the user inputs the vehicle number, the management server 30 identifies the usage log associated with the vehicle number from the vehicle database, and obtains data indicating that the vehicle door of the vehicle is unlocked from the portable information terminal 50. Send to. Then, the operation screen 500 on the display of the portable information terminal 50 is switched as shown in FIG. That is, only the locked image 506 is highlighted. The highlighted display mode is the same as in the case of FIG.

When the user touch-operates the lock image 506, the instruction analysis unit 406 sends the data indicating that the lock instruction has been input to the management server 30 through the second communication control unit 405 together with the vehicle number, the current position, and the current date and time. And the second control signal described above is output and is transmitted to the electronic key storage device 1 through the first communication control unit 404.
The management server 30 updates the usage log of the vehicle database based on the received data (records the locking date and time). In the electronic key storage device 1, the operation tool 1322 of the second solenoid 132 presses the lock button 22 of the electronic key 20 upon receiving the first control signal. As a result, the vehicle door is locked by the original function of the electronic key 20.

As described above, according to the electronic key storage device 1 of the present embodiment, a method of sharing the electronic key unique to the vehicle for contactlessly unlocking or locking the vehicle door of the vehicle that can be shared by a plurality of users is provided. It can be implemented easily. That is, the electronic key storage device 1 placed in the passenger compartment of the vehicle holds the electronic key 20 unique to the vehicle, which has the unlock button 21 and the lock button 22, and is unlocked by the first control signal. A pressing mechanism is provided that presses the button 21 and presses the lock button 22 according to the second control signal described above, and each user holds the portable information terminal 50 so that the electronic key 20 exists in the vehicle cabin. ..
As a result, management of one electronic key 20 can be realized easily and at low cost without modifying the existing electric system and electronic key system.

The electronic key storage device 1 selectively presses the unlock button 21 or the lock button 22 of the electronic key 20 by Bluetooth communication with the portable information terminal 50 that is operated outside the vehicle compartment, so that an interference radio wave or a noise signal is generated. It is possible to reduce the situation of malfunction by receiving the information such as

The electronic key storage device 1 also enables energization to the Bluetooth communication and the pressing mechanism by fitting the electronic key 20 into the fitting holder 111, and restricts energization when the electronic key 20 separates from the fitting holder 111. Since the switch 113 is provided, it is possible to prevent waste of electric power and malfunction of the electronic key storage device 1 when the electronic key 20 is taken out, and also to store the electronic key depending on whether short range communication by the portable information terminal 50 is possible or not. It is possible to easily check whether the electronic key 20 is stored in the device 1 from the inside or outside of the vehicle.

The pressing mechanism of the electronic key storage device 1 has a plunger 1311 that presses the unlock button 21 when the communication module 12 receives the first control signal and autonomously returns to the state before pressing after pressing. The lock button 22 is triggered by the reception of the first solenoid 131 and the communication module 12 after a certain period of time has elapsed since the reception of the first control signal, or when the communication module 12 receives the second control signal. And a second solenoid 132 having a plunger 1321 that autonomously returns to the state before pressing after pressing. Therefore, a general-purpose small solenoid applying the principle of electromagnet is used at low cost. It is possible to realize a small pressing mechanism.

Since the communication module 12 performs the Bluetooth communication in which the pairing is started according to the predetermined information and the pairing is released when the energization is stopped, the electronic key storage device 1 can be manufactured at low cost by using general-purpose components.

[Modification]
In the first embodiment, the example in which the electronic key 20 has the unlock button 21 and the lock button 22 has been described, but a function of unlocking the bonnet or the rear door may be added. It is possible. In this case, in FIG. 8C and FIG. 8D, in addition to the unlock button 21 and the lock button 22, the bonnet unlock button and the like are displayed, and when the unlock button is touch-operated. The third control signal may be generated at a timing different from that of the first control signal and the second control signal, which becomes significant only during the period from disable to enable. Further, when it is sufficient to unlock the locked vehicle door, only the unlock button 21 may be provided.

In the first embodiment, the example in which the user can visually recognize the vehicle number of the shared vehicle has been described, but the management server 30 may integrally manage which vehicle is available. In this case, the user operates the portable information terminal 50 to send a search request for a bookable vehicle to the management server 30 together with the current position and the current time. The management server 30 causes the display of the portable information terminal 50 to display the vehicle numbers of one or more vehicles within a predetermined distance range from the current position. The user will input any of the vehicle numbers according to the operation screen 500 of FIG. 8B.

In the first embodiment, an example has been described in which the authentication code used when performing the Bluetooth communication with the electronic key storage device 1 is received from the management server 30, but when it is sufficient to manage each family or organization, The management server 30 does not necessarily have to be provided. In this case, the authentication code can be paired with the electronic key storage device 1 in the portable information terminal 50 that the family member or the organization member has in advance, but the authentication code different from that of another person is stored. However, this may be used for automatic or manual pairing.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the second embodiment, the structure of the pressing mechanism 13 is different from that of the first embodiment. FIG. 9 is a diagram showing a structural example of the pressing mechanism according to the second embodiment. For the sake of convenience, parts having the same functions as those shown in the first embodiment will be described with the same reference numerals. The pressing mechanism of the second embodiment uses a cantilever structure as another example that moves up and down with respect to the fixed position of the electronic key 20, so that the pressing mechanism is simpler and lower than the pressing mechanism 13 of the first embodiment. The electronic key storage device is realized at a cost. In the second embodiment, the cantilever structure for pressing the unlock button 21 of the electronic key 20 is referred to as a first cantilever structure 231 and the cantilever structure for pressing the lock button 22 of the electronic key 20 is referred to as a first cantilever structure. 2 cantilever structure 232.

The first cantilever structure 231 is configured to include a rigid rod body 2311 having both ends and a support body 2312 having a hinge structure. The rod body 2311 corresponds to the connector 1312 of the pressing mechanism 13 of the first embodiment. A screw hole is formed at one end of the rod body 2311. The other end of the rod body 2311 is a free end, and a magnetic body 2313 having a predetermined shape and weight is fixed to the lower side, that is, the end surface facing the base portion 101. Further, an operation tool 2314 is fixed to a portion of the central portion of the rod body 2311 that points the unlock button 21. The operating tool 2314 is made of the same material as the operating tool 1313 in the pressing mechanism 13 of the first embodiment.

The support body 2312 sandwiches one end of the rod body 2311 at a position slightly higher than the thickness (height of the electronic key 20 in the direction away from the base portion 101) when the electronic key 20 is housed in the fitting holder 111. , A bolt is loosely fitted in the screw hole of the rod body 2311 (the bolt is fitted and fixed in a state where the inner surface of the screw hole of the rod body 2311 and the bolt foot surface are slidable with each other), and one end of the rod body 2311 is rotated. Support freely. The other end of the rod body 2311 can be displaced by 180 degrees or more with one end as a base point when the fitting holder 111 is taken in and out, and when the electronic key 20 is housed in and removed from the fitting holder 111.

An electromagnet 2315 is provided in a portion of the lower bottom portion 101a of the base portion 101, which faces the magnetic body 2313 fixed to the other end (free end) of the rod body 2311. The electromagnet 1314 operates by the operation of the control circuit 133 (not shown) so that the electromagnet 1314 is energized for a time during which the first control signal is enabled and magnetically attracts the magnetic body 2313. The magnetic body 2313 is displaced downward by its own weight and the attractive force of the electromagnet 2315. As a result, the operating tool 2314 presses the unlock button 21. When the first control signal is disabled, the magnetic force disappears, the magnetic body 2313 separates from the electromagnet 2315, and accordingly, the operating tool 2314 also separates from the unlock button 21.

Like the first cantilever structure body 231, the second cantilever structure body 232 includes a rigid rod body 2321 having both ends and a support body 2322 having a hinge structure. The rod body 2321 corresponds to the connector 1322 of the pressing mechanism 13 of the first embodiment. A screw hole is formed at one end of the rod body 232. The other end of the rod body 2321 is a free end, and a magnetic body 2323 having a predetermined shape and weight is fixed to the end face directed downward. Further, an operation tool 2324 is fixed to a portion of the central portion of the rod body 2321 that points the lock button 22. The operating tool 2324 has the same shape and material as the operating tool 1323 in the pressing mechanism 13 of the first embodiment.

The support body 2322 sandwiches one end portion of the rod body 2321 at a position slightly higher than the thickness when the electronic key 20 is housed in the insertion holder 111, and loosely fits the bolt into the screw hole of the rod body 2321. One end of the rod body 2321 is rotatably supported. The other end of the rod body 2321 can be displaced by 180 degrees or more with one end as a base point when the electronic key 20 is housed in or removed from the fitting holder 111. This facilitates accommodation and removal of the electronic key 20.

An electromagnet 2325 is provided in a portion of the lower bottom portion 101a of the base portion 101, which faces the magnetic body 2323 fixed to the other end (free end) of the rod body 2321. The electromagnet 1325 is operated by a control circuit 133 (not shown) so as to energize for a time during which the second control signal is enabled and magnetically attract the magnetic body 2323.
The magnetic body 2323 is displaced downward by its own weight and the attractive force of the electromagnet 2325. As a result, the operation tool 2324 presses the lock button 22. When the second control signal is disabled, the magnetic force disappears, the magnetic body 2323 separates from the electromagnet 2325, and accordingly, the operating tool 2324 also separates from the lock button 22.

It should be noted that the first cantilever structure 231, the second cantilever structure 232, and the electromagnets 2315 and 2325 can be arbitrarily changed in their installation positions independently of each other by deforming the shape of the receptacle 134, for example. It is a thing.

<Modification>
The magnetic bodies 2313 and 2323 are explained on the premise that they are metals such as iron oxide that are easily influenced by the magnetic force of the electromagnets 2315 and 2325 and lose their properties as magnets as soon as the influence of the magnetic force disappears. Can also be used. In this case, the electromagnets 2315 and 2325 have different polarities from the permanent magnet when the first control signal and the second control signal are enabled, and the permanent magnets when the first control signal and the second control signal are disabled. It will be arranged so as to have the same polarity. With such a configuration, the pressing force (when the polarities are different) and the repulsive force (when the polarities are) to the unlocking button 21 and the locking button 22 of the electronic key 20 are stronger than those of a metal such as iron oxide. The effect is obtained.

In addition, in order to freely change the length of the rods 2311 and 3221, for example, two metal plates of the same size having a plurality of screw holes formed thereon are overlapped with each other in a direction opposite to the longitudinal direction. The structure may be such that two metal plates are fastened to the screw hole with a bolt and a nut when the desired length is reached.

[Third Embodiment]
Next, a third embodiment of the present invention will be described. The third embodiment is the same as the second embodiment in the configuration of the pressing mechanism, particularly in using the cantilever structure, but is different in that the force transmission mechanism is formed by gears instead of the magnetic body 2313 and the electromagnet 2314. Different from the second embodiment. In the third embodiment, the cantilever structure for pressing the unlock button 21 of the electronic key 20 is called a first cantilever structure 331, and the cantilever structure for pressing the lock button 22 of the electronic key 20 is referred to as a first cantilever structure. 2 cantilever structure 332. 10A to 10D are views showing a structural example of the pressing mechanism according to the third embodiment from different viewpoint directions. For convenience, parts having the same functions as the parts described in the first and second embodiments will be described with the same reference numerals.

The first cantilever structure 331, instead of the magnetic body 2313 described in the second embodiment, loosely fixes one end of the eccentric connecting rod 3313 to the other end of the rod 2311 with a screw or the like, and also the eccentric connecting rod. The other end of 3313 has n (natural number) teeth and is loosely fixed with a screw or the like to a portion eccentric in the peripheral direction from the center of the large gear 3314 having a tip circle diameter N (natural number). With the rotation of the large gear 3314, the rod body 2311 is configured to be displaced upward (+Z direction) and downward (−Z direction).
Further, instead of the electromagnet 2314 described in the second embodiment, the rotating shaft thereof has m (natural number>n: for example, n/2) teeth, and the tip circle has a diameter of M (natural number<N. ) Is provided with a motor 3316 to which the small gear 3315 is fixed. The motor 3316 is preferably a stepping motor that rotates by a constant angle like a second hand of a clock, but it may be a normal DC motor.

The outer end surface of the large gear 3314 meshes with the gear of the small gear 3315 when the other end of the rod body 2311 is displaced so as to approach the lower bottom portion 101a of the base portion 101 with the support body 2312 at one end as a base point, and When the other end of the rod body 2311 is displaced in the opposite direction, it separates from the outer end surface of the pinion gear 3315.
The large gear 3314 and the small gear 3315 are, for example, a pair of spur gears, bevel gears, bevel gears, and straight bevel gears that have substantially the same tooth depth, tooth trace, tooth width, and pitch formed on the outer end surface. , Bevel gears are used. Each gear is made of any one of carbon steel for machine structure, chrome molybdenum steel, stainless steel, phosphor bronze, aluminum bronze, ductile iron, and nylon.

The spur gear is a gear having a tooth trace parallel to the axis at the center of the gear, and the bevel gear is a gear in which the tooth trace of the spur gear is oblique (helical). Bevel gears have the advantages of higher strength and quieter sound than spur gears because the meshing ratio (contact area) between the gears is large. A bevel gear is a gear having a conical outer shape with teeth, and having a shape like an open umbrella. Depending on the arrangement of the motor 3316, bevel gears having different shaft directions can be combined to transmit power. The straight bevel gear is a gear in which the tooth traces of a bevel gear are linear like a spur gear, and the bevel gear is a bevel gear having diagonal bevels like a bevel gear.

The motor 3316 rotates the pinion gear 3315 in the first direction, for example, counterclockwise for the time when the first control signal is enabled by the operation of the control circuit 133 (not shown), and then the first control signal is disabled. It operates so as to rotate the pinion gear 3315 in the second direction, for example, clockwise for a certain period of time.
The small gear 3315 transmits the rotational force to the large gear 3314. Then, the large gear 3314 converts the rotational force into an up-and-down motion (vertical movement) of the rod body 2311 through the eccentric connecting rod 3313. Thereby, when the control circuit 133 receives the first control signal, the operating tool 2314 presses the unlock button 21, and then the operating tool 2314 separates from the unlock button 21. Since the number of teeth of the small gear 3315 is smaller than that of the large gear 3314, the large gear 3314 can be rotated largely with a small amount of rotation.

The second cantilever structure 332 has the same configuration as the first cantilever 331.
That is, instead of the magnetic body 2323, one end of the eccentric connecting rod 3323 is loosely fixed to the other end of the rod body 2321 with a screw or the like, and the other end of the eccentric connecting rod 3323 has n teeth. Then, loosely fix the large gear 3324 having a tip circle diameter N from the center of the large gear 3324 in the peripheral direction with screws or the like, and the rod body 2321 moves upward (+Z direction) and downward as the large gear 3324 rotates. It is configured to be displaced in the (−Z direction).
Further, instead of the electromagnet 2324, a small gear 3325 having m (>n: for example, n/2) number of teeth and a tip circle diameter of M (<N) is fixed to the rotation shaft thereof. A motor 3326 is provided. The types and materials of the gears 3324 and 3325 are the same as those of the first cantilever structure body 331. The motor 3326 is preferably a stepping motor that rotates at a constant angle like a second hand of a clock, but it may be a normal DC motor.

The outer end surface of the large gear 3324 is joined to the gear of the small gear 3325 when the other end of the rod body 2321 is displaced so as to approach the lower bottom portion 101a of the base portion 101 with the support body 2322 at one end as a base point, and the other end When the other end of the rod body 2321 is displaced in the opposite direction, it separates from the outer end surface of the pinion gear 3325. The large gear 3324 and the small gear 3325 are, for example, a pair of spur gears, bevel gears, bevel gears, and straight bevel gears, which have tooth teeth, tooth lines, tooth widths, and pitches that are substantially the same formed on the outer end surface. , Bevel gears are used. The outline of each gear is as described for the first cantilever structure 331.

The motor 3326 rotates the pinion gear 3325 in the first direction, for example, counterclockwise for the time when the second control signal is enabled by the operation of the control circuit 133 (not shown), and then the second control signal is disabled. It operates to rotate the pinion gear 3325 in a second direction, for example clockwise, for a fixed time.
The small gear 3325 transmits the rotational force to the large gear 3324. Then, the large gear 3324 converts the rotational force into a vertical movement (vertical movement) of the rod body 2321 through the eccentric connecting rod 3323. Accordingly, when the control circuit 133 receives the second control signal, the operating tool 2324 presses the lock button 22, and then the operating tool 2324 separates from the lock button 22. Since the number of teeth of the small gear 3325 is smaller than that of the large gear 3324, the large gear 3324 can be rotated largely with a small amount of rotation.

First cantilever structure 331, second cantilever structure 332, motor 331
The installation positions of 316 and 3326 can be changed independently of each other by deforming the shape of the receptacle 134, for example.
