The first terminal 41 is an example of the “first supply terminal” and the “power supply terminal” of the present invention.

  The second terminal 42 is a terminal for supplying power to the user terminal held by the second holding unit 20. The second terminal 42 is an example of the “second supply terminal” and the “power supply terminal” of the present invention. The first terminal 41 and the second terminal 42 are, specifically, an electrode group conforming to the shape of the terminal of the user terminal to which the own terminal is connected, and a circuit for stably supplying power to the user terminal. Having. Further, the first terminal 41 and the second terminal 42 also have circuits for the user terminal to transmit and receive data to and from another device.

  The external power supply terminal 43 is a terminal connected to an external power supply. The external power supply terminal 43 is an example of the “external terminal” of the present invention. The first wiring 44 electrically connects the first terminal 41 and the external power supply terminal 43. The second wiring 45 electrically connects the second terminal 42 and the external power supply terminal 43. The first wiring 44 and the second wiring 45 are examples of the “wiring” of the present invention. Specifically, the external power supply terminal 43 has a circuit that distributes power supplied from an external power supply to the first wiring 44 and the second wiring 45.

The first terminal 41 and the second terminal 42 are provided at positions corresponding to the shape of the user terminal. In order to explain the arrangement of both terminals, the user terminal of this embodiment will be described with reference to FIG.
FIG. 2 shows an example of a user terminal held by the user terminal case 1. FIG. 2A illustrates a smartphone 80. The smartphone 80 includes a touch screen 81 that displays an image, a power terminal 82, a battery 84, and a speaker 85.

  The touch screen 81 displays an image and receives a user operation. The power terminal 82 is a terminal for connecting a terminal for supplying power and transmitting and receiving a signal. The power terminal 82 is an example of the “power supply terminal” of the present invention. The power terminal 82 is provided inside the insertion port 83. The battery 84 accumulates power and supplies power to each unit of the device. The speaker 85 outputs the voice of the other party.

  FIG. 2B shows a touch panel display 90. The touch panel display 90 includes a touch screen 91, a power terminal 92 provided at the back of the insertion port 93, and a battery 94. These are the same hardware as each unit of the same name provided in the smartphone 80. However, unlike the smartphone 80, the touch panel display 90 is a terminal specialized in a function of displaying an image and a function of receiving an operation.

  For this reason, the touch panel display 90 has a smaller battery than the smartphone 80 and a correspondingly larger battery 94. The smartphone 80 has a rectangular plate shape, and a power terminal 82 is provided at the center of the lower side surface (a speaker 85 that is placed on the user's ear is provided above the smartphone 80). .

  The lower side support plate 113 of the first holding unit 10 supports the surface having the insertion port 83 of the power terminal 82 (that is, the lower side surface) when the smartphone 80 is held by the first holding unit 10. . The lower support plate 113 is an example of the “support plate” of the present invention. The first terminal 41 is provided at a position on the lower side support plate 113 where the smartphone 80 is inserted into the insertion port 83 of the smartphone 80 when the smartphone 80 is held by the first holding unit 10.

  FIG. 3 shows a state where the user terminal is held. FIG. 3A illustrates the smartphone 80 before being held by the first holding unit 10. As shown in FIG. 3A, the entirety of the smartphone 80 is fitted into the side surface holding portion 11 while inserting the first terminal 41 into the insertion port 83 of the smartphone 80, and as shown in FIG. Is held by the first holding unit 10.

  As shown in FIG. 2B, the touch panel display 90 has a rectangular plate shape like the smartphone 80, and a power terminal 92 is provided at the center of the lower side surface. When the touch panel display 90 is held by the second holding unit 20, the lower surface support plate 213 of the second holding unit 20 supports the surface having the insertion port 93 of the power terminal 92 (that is, the lower side surface). I do.

  The second terminal 42 is provided in the lower side support plate 213 at a position where the touch panel display 90 is inserted into the insertion port 93 of the touch panel display 90 when the second holding unit 20 holds the touch panel display 90. As shown in FIG. 3A, by inserting the entirety of the touch panel display 90 into the side surface holding portion 21 while inserting the second terminal 42 into the insertion port 93 of the touch panel display 90, as shown in FIG. The touch panel display 90 is held by the second holding unit 20.

A more detailed method for fitting the entirety of the smartphone 80 to the side holding unit 11 will be described with reference to FIG.
FIG. 4 illustrates an example of the movement of the lower side support plate 113. The lower side support plate 113 is configured such that at least a portion where the first terminal 41 is provided moves toward the outside of the space where the smartphone 80 is held. The lower side support plate 113 has a rotating shaft member 115 on the side of the rear holding unit 12.

  The rotating shaft member 115 is rotatably supported by, for example, a left side support plate 112 and a right side support plate 114. Therefore, the lower side support plate 113 is supported so as to be rotatable about the rotation shaft member 115. FIG. 4A illustrates the lower side support plate 113 before rotation. The lower side support plate 113 has, for example, a shape in which both ends are fitted into the left side support plate 112 and the right side support plate 114, and the state illustrated in FIG. 4A is maintained unless a user intentionally applies a force. It is supposed to be.

  In the state of FIG. 4A, the first terminal 41 side of the lower side support plate 113 is a space B80 in which the smartphone 80 is held. When a force in the direction A1 toward the outside of the space B80 is applied, the lower side support plate 113 is released from the fitted state at both ends, and moves (rotates) in the direction A1 as shown in FIG. 4B. . The user inserts the first terminal 41 into the insertion port 83 of the smartphone 80 with the lower side support plate 113 moved (rotated) as shown in FIG. 4C.

  Then, the user moves (rotates) the lower side support plate 113 in the direction A2 opposite to the direction A1 (the direction toward the space B80) with the first terminal 41 completely inserted. Then, the entirety of the smartphone 80 is fitted into the side holding unit 11, and the smartphone 80 is held by the first holding unit 10 as illustrated in FIG.

  When fitting the entire touch panel display 90 to the side surface holding unit 21, the user rotates the lower side support plate 213 as in the example shown in FIG. The user terminal case 1 is used in a state where the smartphone 80 is held by the first holding unit 10 and the touch panel display 90 is held by the second holding unit 20 as shown in FIG. It is assumed that the external power supply terminal 43 is connected to the external power supply in this state.

  FIG. 5 shows an example of the user terminal case 1 connected to an external power supply. In FIG. 5, a power cable 50 having a terminal 51 connectable to the external power supply terminal 43, a wiring 52, and an outlet plug 53 is connected to the external power supply terminal 43. When the outlet plug 53 is inserted into the outlet, the power supplied from the external power supply via the power cable 50 is supplied to the smartphone 80 via the first wiring 44 and the first terminal 41.

  This electric power is supplied to the touch panel display 90 via the second wiring 45 and the second terminal 42. As described above, in this embodiment, power can be supplied (charged) to two user terminals (smartphone 80 and touch panel display 90) by using only one power cable 50. Therefore, the convenience in charging two terminals can be improved as compared with the case where two power cables are used to charge two user terminals.

  Further, in the user terminal case 1, power supply terminals (first terminal 41 and second terminal 42) are arranged so as to be inserted into the user terminal while holding the user terminal. The user terminal into which these power supply terminals are inserted is prevented from being caught by the power supply terminals when a force is applied to the user terminal from the holding units (the first holding unit 10 and the second holding unit 20). ing.

  Further, in the user terminal case 1, as shown in FIG. 4, when the power supply terminal is inserted into the insertion port (the insertion ports 83 and 93) of the user terminal, the lower side support plates (lower side support plates 113 and 213) are used. Move). In this embodiment, the user terminal can be easily held in the user terminal case as compared with a case where the lower side support plate is fixed and does not move, for example.

[2] Modifications The embodiment described above is merely an example of the embodiment of the present invention, and may be modified as follows.

[2-1] Support Plate The support plate provided in the side surface holding units (side surface holding units 11 and 21) is not limited to the one described in the embodiment. For example, the support plate on which the power supply terminals (the first terminal 41 and the second terminal 42) are provided is not limited to the lower side, and may be on the upper side or the left and right sides as long as the position corresponds to the insertion port of the user terminal.

  Further, in the embodiment, the support plate is moved as shown in FIG. 4, but the present invention is not limited to this. For example, when the support plate is formed of a soft, ductile rubber or the like, the user may move toward the outside of the space where the user terminal is held by pulling the support plate. Even in this case, the user terminal can be easily held in the user terminal case as compared with the case where the support plate is fixed and does not move.

[2-2] Arrangement of Power Supply Terminals The arrangement of the power supply terminals (the first terminal 41 and the second terminal 42 in the embodiment) may be different from that of the embodiment. For example, when the user terminal case holds a user terminal different from the smartphone 80 and the touch panel display 90, the power supply terminal may be disposed at a position corresponding to the position of the insertion port provided in the user terminal. .

The corresponding position is a position where the power supply terminal is just inserted into the outlet when the user terminal is held in the user terminal case. In addition, the arrangement of the power supply terminals may be variable in order to hold a plurality of user terminals having different positions of the insertion ports.
FIG. 6 shows an example of the lower side support plate and the power supply terminal of this modification. FIG. 6 illustrates the lower side support plate 113a, the terminal portion 47a, and the first wiring 44a.

  The terminal portion 47a has a first terminal 41a and a moving table 46a. The lower side support plate 113a supports the movable table 46a movably along the longitudinal direction A3. The longitudinal direction A3 is a direction along the side surface of the user terminal. The movable base 46a has a first terminal 41a fixed to the user terminal side, and a first wiring 44a attached to the opposite side. The first terminal 41a and the first wiring 44a are electrically connected.

  That is, the lower side support plate 113a has a shape that moves the terminal portion 47a provided with the first terminal 41a along a surface having an insertion port of the user terminal (for example, a lower side surface). By moving the terminal portion 47a along this surface, the terminal portion 47a can be moved to insert the first terminal 41a into the insertion port, regardless of where the insertion port holds the user terminal provided. it can.

It should be noted that there are other methods for making the arrangement of the power supply terminals variable.
FIG. 7 shows another example of the lower side support plate and the power supply terminal of this modification. FIG. 7 illustrates a plurality of lower side support plates 113b, 113c, 113d, and 113e in which the arrangement of the power supply terminals is different. FIG. 7A illustrates the lower side support plate 113b in which the first terminal 41 is disposed at the center in the longitudinal direction A3.

  FIG. 7B illustrates a lower side support plate 113c in which the first terminal 41 is disposed closer to an end in the longitudinal direction A3 than the lower side support plate 113b. FIG. 7C illustrates a lower side support plate 113d in which the first terminal 41 is disposed closer to an end in the longitudinal direction A3 than the lower side support plate 113c. FIG. 7D illustrates the lower side support plate 113e in which the first terminal 41 is disposed closer to the end in the longitudinal direction A3 than the lower side support plate 113d.

  In the example of FIG. 7, for example, from the state in which the first holding unit 10b includes the lower side support plate 113b, the lower side support plate 113b can be replaced with other lower side support plates 113c, 113d, and 113e. The lower surface support plates 113c, 113d, and 113e are support plates at which the first terminals 41 are provided, which are different from the lower surface support plate 113b. The replacement of the lower side support plate is performed, for example, as follows.

  For example, when the rotating shaft member 115 shown in FIG. 4 is detachable from the left side supporting plate 112 and the right side supporting plate 114, the rotating shaft member 115 of the lower side supporting plate 113b is removed, and a new lower side supporting plate is removed. Is attached. Alternatively, a protrusion may be provided on the lower side support plate 113b, and the protrusion may be inserted into a recess of the rear holding unit 12, so that the support plate may be detachable.

  The lower side support plate shown in FIG. 7 is an example, and a lower side support plate in which the first terminal 41 is arranged at a position corresponding to the insertion port of the user terminal which may be held is used. You may be. In the example of FIG. 7, if the position of the insertion port matches the arrangement of the first terminals 41 on the replaceable support plate, a plurality of types of user terminals having different positions of the insertion port are used in the user terminal case. Can be used.

[2-3] Built-in wiring In the embodiment, the first wiring 44 and the second wiring 45 are exposed, but these wirings may be built-in and become invisible.
FIG. 8 shows an appearance of a user terminal case 1f of the present modification. The user terminal case 1f does not include the exposed first wiring 44 and second wiring 45 shown in FIG.

  Instead of these wirings, the user terminal case 1f includes a first holding unit 10f in which the first wiring 44f is embedded, a second holding unit 20f in which the second wiring 45f is embedded, the first wiring 44f, and the second wiring 44f. A connection portion 30f in which the wiring 45f is embedded. For example, the rear holding portion 12f of the first holding portion 10f is formed of a synthetic resin, and a hole through which wiring is passed is formed in advance in a plate-shaped synthetic resin. The first terminal 41 and the external power supply terminal 43 are electrically connected by a first wiring 44f passing through the hole.

  Further, the second terminal 42 and the external power supply terminal 43 are also electrically connected by the second wiring 45f passing through a hole formed in the back surface holding portion 22f. If the wiring is exposed, for example, a problem may occur that the wiring is erroneously pulled and disconnected. In this modification, the wiring is buried as shown in FIG. 8, so that it is possible to prevent the occurrence of a problem due to the application of a pulling force to the wiring. Further, since the wiring is not visible, the appearance of the user terminal case can be simplified as compared with the case where the wiring is exposed.

[2-4] Charging Method In the embodiment, charging by wire is performed, but charging by wireless (so-called wireless charging) may be performed.
FIG. 9 shows an appearance of a user terminal case 1g of the present modification. The user terminal case 1g includes embedded first and second wirings 44g and 45g instead of the exposed first and second wirings 44 and 45 shown in FIG.

  One end of the first wiring 44g is connected to the external power supply terminal 43, and the other end is connected to a wireless charging coil 48g. The coil 48g is embedded in the back holding part 12g of the first holding part 10g, similarly to the first wiring 44g. One end of the second wiring 45g is connected to the external power supply terminal 43, and the other end is connected to a wireless charging coil 49g. The coil 49g is embedded in the back surface holding portion 22g of the second holding portion 20g, like the second wiring 45g.

  As described above, in the user terminal case 1g, the wireless charging coil 48g is provided in the first holding unit 10g, and the wireless charging coil 49g is provided in the second holding unit 20g. In the case of charging via a terminal, a terminal to be inserted into the insertion port is present as a protrusion, and if the user performs rough handling, the terminal may be broken and cause a disconnection.

  In the present modified example, as shown in FIG. 8, a terminal to be inserted into the user terminal is not required, so that disconnection due to damage to the terminal does not occur. Further, since there is no terminal to be inserted into the user terminal, the appearance of the user terminal case can be simplified as compared with the case where the terminal is provided.

[2-5] Charging between terminals Some user terminals have a function (power supply function) of supplying power to another terminal using a battery provided in the terminal itself. In the present modification, charging using the power supply function is performed.

  FIG. 10 illustrates an example of a hardware configuration of each terminal according to the present modification. 10, a first terminal 41h including a charging circuit 411, a power supply circuit 412, and a changeover switch 413, and a second terminal 42h including a charging circuit 421, a power supply circuit 422, and a changeover switch 423 are illustrated. ing. FIG. 10 illustrates an external power supply terminal 43 h including a distribution circuit 431, a relay circuit 432, and a changeover switch 433.

  The charging circuit 411 is a circuit for stably supplying power to a user terminal (the user terminal held in the first holding unit 10) to which the first terminal 41h is connected. The power supply circuit 412 is a circuit for outputting power supplied from a user terminal to which the first terminal 41h is connected (a user terminal held in the first holding unit 10). The changeover switch 413 is a switch that switches between the charging circuit 411 and the power supply circuit 412.

  The charging circuit 421 is a circuit for stably supplying power to a user terminal to which the second terminal 42h is connected (a user terminal held in the second holding unit 20). The power supply circuit 422 is a circuit for outputting power supplied from a user terminal (a user terminal held in the second holding unit 20) to which the second terminal 42h is connected. The changeover switch 423 is a switch that switches between the charging circuit 421 and the power supply circuit 422.

  The distribution circuit 431 is a circuit that distributes the power supplied from the external power supply to the wiring connected to the first terminal 41h and the wiring connected to the second terminal 42h. The relay circuit 432 is a circuit that relays power transmission from the first terminal 41h to the second terminal 42h or power transmission from the second terminal 42h to the first terminal 41h. The changeover switch 433 is a switch that switches between the distribution circuit 431 and the relay circuit 432.

  The changeover switch 413, the changeover switch 423, and the changeover switch 433 each include a physical switch that can be manually switched by a user and a logical switch that can be switched by a control signal transmitted to each other. For example, when the charging circuit 411 is manually selected, the first terminal 41h functions as a charging terminal that relays charging of the user terminal held in the first holding unit 10.

  When the charging circuit 421 is manually selected, the second terminal 42h functions as a charging terminal that relays charging to the user terminal held in the second holding unit 20. When the first terminal 41h and the second terminal 42h both function as charging terminals (both when a charging circuit is selected), the external power supply terminal 43h selects the distribution circuit 431 to supply power to both terminals. Functions as a distribution terminal for distribution to the

  When manually switched to the power supply circuit 412, the first terminal 41h functions as a power transmission terminal that relays power transmission from the user terminal held in the first holding unit 10 to another device. At this time, the changeover switch 413 notifies the changeover switch 423 and the changeover switch 433 that the power supply circuit 412 has been changed. When the power supply circuit 412 is selected, the changeover switch 423 switches the logic switch to the charging circuit 421 because charging cannot be performed even when power is transmitted from the first terminal 41 h (when the charging circuit 421 is selected, the switching is performed as it is. Do not do).

  When the distribution circuit 431 is selected, the switch 433 switches to the relay circuit 432 because the relay cannot be performed even if power is transmitted from the first terminal 41h (when the relay circuit 432 is selected, the switching is performed as it is. Not performed). By performing the above switching, the second terminal 42 h receives the power transmitted from the user terminal held in the first holding unit 10 via the first terminal 41 h and held in the second holding unit 20. Supply to the user terminal.

  In this modification, the direction of power supply may be reversed. In this case, the second terminal 42h functions as a power transmission terminal that relays power transmission from the user terminal held in the second holding unit 20 to another device when manually switched to the power supply circuit 422. Then, the first terminal 41h receives power transmitted from the user terminal held in the second holding unit 20 via the second terminal 42h and supplies the power to the user terminal held in the first holding unit 10. .

  In the present modification, power can be supplied from the user terminal held in the first holding unit 10 to the user terminal held in the second holding unit 20. Therefore, even when the external power supply terminal 43h cannot be connected to the external power supply, for example, when the remaining battery level of one user terminal is low, the user operates the changeover switch, so that the remaining battery level is large. It is possible to charge the user terminal whose remaining battery power is low due to the power supply of the user terminal that is running.

[2-6] Automatic Adjustment of Battery Remaining In the above modified example, the user performed the first switching of the switch. In this modification, the switching is automatically performed based on the remaining battery level of the user terminal.

  FIG. 11 illustrates an example of a hardware configuration of each terminal according to the present modification. FIG. 11 illustrates a first terminal 41j including a switch control unit 413j instead of the switch 413 illustrated in FIG. 10, and a second terminal 42j including a switch control unit 423j instead of the switch 423. FIG. 11 illustrates an external power supply terminal 43j including a switching control unit 433j instead of the changeover switch 433 illustrated in FIG.

  The switching control unit 413j, the switching control unit 423j, and the switching control unit 433j are computers including a processor, a memory, and a storage in addition to the physical switch and the logical switch described in the description of FIG. These control units perform switch switching based on their own judgment in addition to switch switching triggered by user operation described in the description of FIG. Hereinafter, these control units are collectively referred to as “switch control unit 403j”.

  In this modification, the user terminal connected to the first terminal 41j supplies remaining amount data indicating the remaining battery amount of the terminal to the switching control unit 413j. Further, the user terminal connected to the second terminal 42j supplies remaining amount data indicating the remaining battery amount of the terminal to the switching control unit 423j. In this modification, each user terminal executes a program for generating and supplying remaining amount data.

  The switch control unit 403j compares each remaining amount indicated by the remaining amount data supplied from each user terminal, and compares the remaining amount between the user terminal held in the first holding unit 10 and the user terminal held in the second holding unit 20. The first terminal 41j, the second terminal 42j, and the external power supply terminal 43j are controlled so as to transmit power from the one with the largest remaining battery to the one with the smallest remaining battery. This control may be performed by any of the switching control unit 413j, the switching control unit 423j, and the switching control unit 433j, or may be performed by two or more switching control units in cooperation.

  In a state where external power is not supplied, for example, when the remaining battery powers of both user terminals are equal to or more than a first threshold value (for example, 20% or the like), the switch control unit 403j outputs the first terminal 41j and the second terminal 41j. 42j are both charging circuits, and neither power supply is performed. The switch control unit 403j performs the above-described power supply control when the remaining battery power of any of the user terminals is less than the first threshold.

  Specifically, the switch control unit 403j switches the terminal of the user terminal having the larger remaining battery to the power supply circuit and switches the external power supply terminal 43j to the relay circuit 432. By this switching, power supply from the user terminal having the higher remaining battery level to the user terminal having the lower remaining battery level is started. For example, in the case of the smartphone 80 and the touch panel display 90 of the embodiment, power is easily supplied from the touch panel display 90 having a large battery to the smartphone 80 (of course, power may be supplied in the opposite direction).

  Further, the switch control unit 403j is configured to stop the first terminal 41j, the second terminal 42j, and the external power supply terminal so that the power transmission is stopped when the remaining battery level of the user terminal to which power has been supplied becomes equal to or more than a second threshold value (for example, 40%). 43j. Specifically, the switch control unit 403j switches the terminal of the user terminal having the larger remaining battery to the charging circuit, and switches the external power supply terminal 43j to the distribution circuit 431. By this switching, power transmission between the user terminals is stopped.

The switch control unit 403j executes a switching process for switching a terminal circuit based on the above configuration.
FIG. 12 illustrates an example of an operation procedure in the switching process. First, the switch control unit 403j acquires remaining amount data from two user terminals held by the user terminal case (step S11). Next, the switch control unit 403j determines whether or not both the remaining battery amounts indicated by the obtained remaining amount data are equal to or greater than the first threshold value (Step S12), and both are equal to or greater than the first threshold value (YES). If the judgment is made, the process returns to step S11 to continue the operation.

  If it is determined that one of them is not equal to or greater than the first threshold value (NO), the switch control unit 403j sets a terminal connected to the user terminal having the larger remaining battery level among the first terminal 41j and the second terminal 42j to the power supply circuit. (Step S13). Further, the switch control unit 403j switches the external power supply terminal 43j to the relay circuit 432 (Step S13). With this operation, power supply between the user terminals is started. Next, the switch control unit 403j acquires remaining amount data again (step S14).

  Subsequently, the switch control unit 403j determines whether the remaining battery level indicated by the remaining level data acquired from the charging-side user terminal is equal to or greater than a second threshold (step S15). If the switch control unit 403j determines in step S15 that the battery level is not equal to or greater than the second threshold (NO), the switch control unit 403j determines whether the battery level indicated by the level information obtained from the power supply side user terminal is equal to or greater than the first threshold. A determination is made (step S16).

  If the switch control unit 403j determines that the value is equal to or more than the first threshold value in step S16 (YES), the process returns to step S14 to continue the operation. If the switch control unit 403j determines that the value is equal to or greater than the second threshold value in step S15 (YES), the terminal switched to the power supply circuit is switched to the charging circuit, and the external power supply terminal 43j is switched to the distribution circuit 431 (step S17). .

  The switch control unit 403j also performs the operation of step S17 when determining in step S16 that the difference is not equal to or larger than the first threshold (NO). Then, the switch control unit 403j ends the operation procedure after the operation in step S17. When the switching control according to the present modification is performed, the remaining battery levels of the two user terminals held in the user terminal case can be brought closer to each other as compared with a case where the switching control is not performed. The operation time of the user terminal can be made closer.
