FIG. 3B is a sectional view taken along line BB in FIG. 1, FIG. 3 shows a hinge mechanism, FIG. 3A is a plan view, and FIG. 3B is a sectional view taken along line CC. is there.

  The portable charger shown in FIGS. 1 to 3 is a device for charging a rechargeable battery mounted on a portable information device such as a mobile phone or a portable game device, and the charger main body 11 is flat. It is formed in a rectangular box shape. A panel storage chamber 13 having an opening 12 at the top is provided inside the charger main body 11, and a battery chamber 14 is provided at one end of the panel storage chamber 13 via a partition plate 13 a.

  The battery chamber 14 houses a rechargeable battery 15 that can store electricity. A terminal block 17 having a connection terminal 16 detachably connected to an external terminal of the portable information device is provided on the upper part of the charging battery 15. A through hole 18 through which the terminal block 17 can project and retract is provided on the side wall of the charger main body 11 facing the front end surface of the terminal block 17. The terminal block 17 is slidably supported by a guide member 19 as a projecting and retracting guide mechanism, and a lock member 20 constituting a lock mechanism is fixed to the terminal block 17.

  The lock member 20 is bent in a substantially L shape, and the upper lock claw 21 is provided so as to protrude upward through a guide hole 23 provided in the upper surface plate 22 constituting the battery chamber 14. That is, by sliding the lock member 20 along the guide hole 23, the terminal block 17 protrudes from the through hole 18, and at the same time, the lock claw 21 protrudes from the opening edge of the opening 12 of the charger body 11. It has become.

  In the opening 12 of the charger main body 11, an end edge 11a opposite to the battery chamber 14 and the left and right edges 11b, 11c of the opening 112 are respectively provided with a plurality of deployment panels 25a via hinge mechanisms 24a-24c. To 25c. The development panels 25a to 25c are thin plates and are formed in a size that can be stored in a plane in the panel storage chamber 13 of the charger body 11.

  Since the hinge mechanisms 24a to 24c and the plurality of deployment panels 25a to 25c have the same structure, only one (the hinge mechanism 24c and the deployment panel 25c of the left edge portion 11c) will be described. That is, the main body side pivot shaft 26 having the pivot hole 26a is provided at both longitudinal ends of the left side edge portion 11c of the charger main body 11. A panel-side pivot shaft 27 having pivot pins 27a at both ends is provided at the center in the longitudinal direction of the development panel 25c.

  The pivot pin 27a of the panel side pivot shaft 27 is pivotally supported in the pivot hole 26a of the main body side pivot shaft 26. Therefore, the expansion panel 25c is rotatable about the pivot pin 27a, and when the expansion panel 25c is rotated inward, the expansion panel 25c is stored in the panel storage chamber 13 (first usage pattern). When 25c is rotated outward, the deployment panel 25c is inverted and deployed outside the charger body 11 (second usage pattern).

  Furthermore, a solar cell 28 made of a thin film is provided on the inner surface of the expansion panel 25c, that is, when the surface is expanded from the charger main body 11 and switched to the second usage pattern. A solar cell 28 made of a thin film is also provided on the inner bottom surface of the panel storage chamber 13. These solar cells 28 are electrically connected to the charging battery 15, and the charging battery 15 is electrically connected to the connection terminal 16.

One end of the torsion spring 29 is locked to the main body side pivot shaft 26 side, and the other end side is locked to the panel side pivot shaft 27 side, and the expansion panel 25c is attached to the charger main body 11 by the elasticity of the torsion spring 29. It is energized in the direction to deploy outward.

  Since the plurality of expansion panels 25a to 25c are configured to be stored in the panel storage chamber 13 of the charger main body 11 in the order of the expansion panels 25a, 25b, and 25c in a plane, the hinge mechanisms 24a to 24c. Is attached to the side edge of the charger body 11 with a step. That is, the hinge mechanisms 24a, 24b, and 24c are provided in the order from the low position to the high position of the side edge of the charger body 11, and the deployment panels 25a to 25c are placed in the panel storage chamber 13 of the charger body 11 without interfering with each other. It can be stored.

  Next, the operation of the portable charger configured as described above will be described.

  When the portable charger is not used, as shown in FIG. 1 (a), a plurality of expansion panels 25a to 25c are stored in the panel storage chamber 13 of the charger main body 11, and are the uppermost expansion panels. A lock claw 21 is engaged with the upper edge of 25c. Therefore, the expansion panel 25c is not unintentionally expanded. Further, the terminal block 17 is sunk from the through hole 18 on the side wall of the charger body 11 by the sliding of the lock member 20, so that the terminal block 17 does not interfere with other members when the portable charger is carried. 16 breakage can be prevented in advance.

  Further, when charging the charging battery 15 in the charger main body 11, if the lock member 20 is slid in the direction of the arrow a along the guide hole 23, the terminal block 17 becomes a through hole in the side wall of the charger main body 11. 18 protrudes. At the same time, the lock member 20 is slid in the direction of the arrow a, and the lock claw 21 is unlocked from the upper edge of the deployment panel 25c, which is positioned at the uppermost position.

Therefore, the deployment panel 25c located at the uppermost stage automatically rotates about the pivot pin 27a by the urging force of the torsion spring 29, and is deployed from the panel storage chamber 13 to the outside of the charger main body 11 to be solar cell 28. Is exposed. Next, the unfolding panel 25b located at the second stage is also automatically rotated about the pivot pin 27a by the urging force of the torsion spring 29, and unfolded from the panel storage chamber 13 to the outside of the charger main body 11 and sun. The battery 28 is exposed. Finally, the deployment panel 25a located at the lowermost stage is also automatically rotated about the pivot pin 27a by the urging force of the torsion spring 29, and is deployed from the panel storage chamber 13 to the outside of the charger body 11 to be solar cells. 28 is exposed.

  Therefore, as shown in FIG. 1B, when all the deployment panels 25 a to 25 c are deployed, the solar cells 28 provided on the deployment panels 25 a to 25 c are exposed and the inner bottom surface of the panel storage chamber 13 is exposed. The provided solar cell 28 is also exposed. Each solar cell 28 is in a state where it can receive light, solar energy is converted into electric energy, and a charging current flows from each solar cell 28 to the charging battery 15 to charge the charging battery 15.
