Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply device, and more particularly to a power supply device capable of switching a power supply included in a battery pack itself to various types of power supplies.

[0002]

2. Description of the Related Art Most commonly used power supply switching devices are transformers for converting AC electricity in the market to DC electricity. For example, this type of transformer is capable of converting 110V or 220V voltage in the market. Converting to 5V and powering electrical equipment to which 5V voltage is applied has the disadvantage that individual transformers can only convert electricity in the market to a single voltage, If the electrical equipment requires a voltage of 6V, another 110V transformer must be used to convert the market electricity to 6V voltage. If you are outside, you cannot supply power to electrical equipment with a transformer, and you have to carry a battery and go out.

[0003]

SUMMARY OF THE INVENTION In view of the above problems in the conventional power supply switching device, an object of the present invention is to provide a power supply device capable of switching the power supply of a battery pack to various types of power supplies.

[0004]

In order to achieve the above object, the present invention comprises a storage unit capable of accommodating a battery pack, and a second connector provided in the storage unit.
A case provided with a connector for outputting one or more power supplies on the outside, and each of the connectors provided in the case and outputting the power and the second connector in the storage unit are electrically connected, and the battery pack is provided. A power supply that is housed in the storage unit and converts the output voltage of the battery pack into a plurality of different voltages and outputs the power from a different connector when the first connector and the second connector are electrically connected to each other; And a switching circuit.

[0005] Each connector provided outside the case for outputting power is provided with a third connector for supplying 5V power, a fourth connector for supplying 9V power, and 12 connectors.
It is more preferable to use a fifth connector for supplying V power, or to provide a cover that can open and close the storage section of the case to accommodate a battery pack.

According to the present invention constructed as described above, a battery pack is inserted into a storage portion of a case to electrically connect a first connector and a second connector, and a plurality of power supplies of the battery pack are provided by a power supply switching circuit. And power can be output from the third connector, the fourth connector, and the fifth connector, respectively. Therefore, it is possible to selectively output a desired voltage from a connector that outputs a predetermined voltage as necessary, and to simultaneously charge the battery pack while the battery pack is being converted from a power source. To do so, insert the connector attached to the appliance into any of the third, fourth, and fifth connectors, receive power output from the battery pack power supply, and attach an AC-DC adapter to the power supply switching circuit. In addition, the battery pack can be charged in the opposite direction.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described based on embodiments, but the present invention is not limited to these examples.

As shown in FIGS. 1 and 2, the power supply 2 of the present invention
Is composed of a case 20 and a power supply switching circuit 22.

[0009] The case 20 has a recessed storage portion 201 on a side surface thereof, which is capable of accommodating a general battery pack (the battery pack will be described later). The second connector 203 may be attached to the inner wall surface of the storage unit 201, and a third connector 221 that outputs one or more power sources outside the case 20 may be provided. 4 connector 223, and 5th
Is provided.

The power supply switching circuit 22 is provided in the case 20 and has a second connector 203 and a third power supply switching circuit 22 for converting and outputting the power of the battery pack.
, The fourth connector 223, and the fifth connector 225 are electrically connected to each other, and the power supply switching circuit 22 has been conventionally and generally used, and thus the description thereof is omitted.

The battery pack 10 includes a first connector 101, and the first connector 101 is used to electrically connect to the second connector 203 (the description of the structure of the battery pack 10 is omitted since it is also well known in the related art). In this embodiment, the battery pack 10 can be applied to a battery pack used in a mobile phone, a battery pack of a notebook computer, and other battery packs.

As shown in FIGS. 1 and 2, a power supply switching circuit
22 converts the power of the battery pack 10 to a power supply of 5V, 9V and 12V (other power supplies can also be converted, here, 5V, 9V and 12V
The battery pack 10 can be converted from the direction A into the storage unit 201 of the case 20 (A in FIG. 1).
The first connector 101 and the second connector 203 are electrically connected to each other, and the power supply of the battery pack 10 is converted to 5 V, 9 V, and 12 V by the power supply switching circuit 22, and the third Output is performed from the connector 221, the fourth connector 223, and the fifth connector 225. In addition, the power supply switching circuit 22 can simultaneously charge the battery pack 10 while the battery pack 10 is converting power, and when used, the connector attached to the electric device can be connected to any one of the power supply switching circuits 22. Power can be supplied from the battery pack 10 by inserting it into the output side connector, and the battery pack 10 can be charged.

[0013]

Therefore, if the user carries the battery pack and the power supply of the present invention when going out, the power supply can be switched and charged at any time, and the power supply of the present invention can simultaneously convert various types of power. Since it is possible, a suitable power supply can be supplied to the electric device from the battery pack by inserting the connector of the electric device into any output side connector of the power supply switching circuit for outputting a power supply suitable for the electric device.
