1 to 3 show a charging device according to an embodiment, and are a front explanatory view, a main part rear view when the AC adapter terminal is not used, and a main part rear view when the AC adapter terminal is used.
The external shape of the main body (10) of the charging device is a flat, substantially rectangular parallelepiped with rounded corners and is easy to carry. As the outer shape, a shape that is easy to carry, such as a substantially elliptical column shape, can be adopted as appropriate.

The main body (10) is provided with a control circuit for receiving power from the outside and supplying power to an external mobile terminal, and a battery that is connected to the control unit and can be charged and discharged. As the battery, a chargeable / dischargeable secondary battery such as a lithium ion battery, a nickel cadmium battery, or a small sealed lead-acid battery can be used.
A battery storage box may be provided and a commercially available dry battery may be mounted.
Further, the battery may not be provided.

An AC adapter terminal (20), which is a power receiving terminal that can be connected to an external power supply source such as an AC outlet disposed in a house, is provided at the rear end of the main body (10).
The AC adapter terminal (20) when not in use is accommodated in a recess (11) provided on the outer surface of the main body (10), as shown in FIG.

A substantially rod-shaped shaft body (12) is erected from the main body (10) in the recess (11). The shaft (12) is inserted through the hole (21) of the AC adapter terminal (20). By the engagement between the shaft body (12) and the hole portion (21), the plug portion (22) located at the end of the AC adapter terminal (20) is rotatably supported around the shaft body (12). Is done.
The plug portion (22) can be rotated by 0 to 180 °, and if it is rotated by about 90 ° or more, the plug portion (22) protrudes out of the recess (11) and can be connected to an AC outlet or the like. FIG. 3 shows a state in which the plug portion (22) is rotated 180 °.

  The rotation engagement means of the AC adapter terminal (20) with respect to the main body (10) is arbitrary, and conventionally known engagement means such as uneven fitting can be used as appropriate. Moreover, as long as the shape of the recess (11) can accommodate the AC adapter terminal (20), any shape can be applied.

A power supply terminal (30) through which power is supplied to the mobile terminal to be charged is disposed on the side of the main body (10). That is, one cable (31) is connected to the side surface of the main body (10), the cable (31) branches into two cables (32) (33), and both the cables (32) ( 33) are connected to the dock terminals (34) and (35), respectively.
Instead of the dock terminals (34) and (35), a plurality of Lightning connectors (36) or a plurality of microUSB terminals (37) may be provided similarly.

In the illustrated example, one cable (31) is fixed to the main body (10). However, the connection between the cable (31) and the main body (10) is detachable via a pin jack terminal or the like. Also good. Moreover, the structure which connects a some cable (31) to a main-body part (10) may be sufficient. Further, the cable (31) may be configured not to branch or may be configured to branch into three or more.

A plurality of dock terminals (34), (35) can be connected to a portable terminal having a dock terminal such as iPhone, iPad, iPod, etc., and a plurality of terminals can be charged simultaneously.
The dock terminal is a connection terminal used to connect a portable electronic communication device to an external device, facilitates connection to various external devices, stereo audio output, video output, serial communication transmission / reception, USB Terminals for inputting / outputting various signals such as transmission / reception, FireWire transmission / reception, power supply, and ground are included. Specifically, the following 30-pin connector is provided. 1: F / W_CHG_GND, 2: F / W_CHG_GND, 3: TPA +, 4: USB_D +, 5: TPA-, 6: USB_D-, 7: TPB +, 8: USB_PWR, 9: TPB-, 10: ACC_ID, 11: F / W_CHG_PWR +, 12: F / W_CHG_PWR +, 13: ACC_PWR, 14: RESERVED, 15: USB_GND, 16: DGND, 17: RESERVED, 18: TX, 19: RX, 20: ACC_DET, 21: S_Y, 22: S_C, 23 : CVBS, 24: REM_SENSE, 25: AUDIO_LIN, 26: AUDIO_RIN, 27: AUDIO_LOUT, 28: AUDIO_ROUT, 29: AUDIO_GND, 30: DGND.
In addition, the Lightning connector is a small version of the dock terminal. Compared with the dock terminal, the dock terminal includes analog signal terminals, whereas the Lightning connector is all 8-pin digital signals and is reversible with no front and back. Because of this shape, there is an advantage that it can be easily connected without confirming the orientation.

  According to the charging device as described above, charging to the portable terminal and storing to the internal battery can be performed simultaneously or selectively. To that end, when the AC adapter terminal (20) is connected only to the external power supply source, the battery is charged, and when the power supply terminal (30) is connected only to the portable terminal, the battery is charged. When the power is supplied to the portable terminal, the AC adapter terminal (20) is connected to the external power supply source and the power supply terminal (30) is connected to the portable terminal, the power is supplied to the portable terminal, A control circuit that can charge the battery may be provided.

When a cap is provided on the back surface of the main body (10) and a storage space for the battery is provided under the cap so that the secondary battery is detachable from the main body (10), the battery is charged after charging. It can be removed and used for another electrical product.
Moreover, you may attach the lamp | ramp which shows the remaining capacity of a battery, and a charging / discharging state. Then, the present charging device can be used for checking the battery capacity.
