  The present invention relates to a power supply device, and more particularly to a portable power supply device that supplies power to an electronic device.

Due to the continuous progress of science and technology, electronic products have been reduced in size and become portable. For example, an electronic product such as a mobile phone, a personal digital assist (PDA), a navigator, a mobile Internet device (MID), or an electronic book. These electronic products have the advantage that they are convenient to carry and can be used at any time, but on the other hand, there is a problem that the so-called power holding time becomes insufficient as the processing speed increases.

  Therefore, a portable power supply device having a secondary battery having a larger capacity than the secondary battery provided in the above-described various portable electronic products has been developed. The portable power supply device is used to charge the electronic device that has consumed power. Such a power supply device has the advantage of being convenient for carrying.

  However, the conventional portable power supply device can be charged only by a wired method when charging the power supply device itself or charging the electronic product from the power supply device. For this reason, if the charging cord is lost, charging cannot be performed, resulting in a serious situation. Improvements have been desired in this regard. Therefore, a contactless charging method was developed. However, a portable power supply device that employs a non-contact charging method cannot select charging by a wired method. This is also a drawback.

This device has a non-contact charging method and a wired method, and a portable power supply device that can arbitrarily select a charging method when charging the power supply device itself or charging an electronic product from the power supply device. It is an issue to provide.

  Therefore, as a result of intensive studies in view of the drawbacks found in conventional products, the present inventor has at least one first connector, a transformer module that is electrically connected to the first connector, and an electrical A current collecting unit electrically connected, a booster module electrically connected to the current collecting unit, at least one second connector electrically connected to the booster module, the booster module and the transformer module A wireless transmitter / receiver module that is electrically connected, and a portable power supply that charges the power supply itself or charges an external electronic device using a non-contact charging method or a wired method. Attention was paid and the present invention was completed based on such knowledge.

This device will be specifically described below. The portable power supply device according to claim 1 includes at least one first connector, a transformer module electrically connected to the first connector, a current collecting unit electrically connected to the transformer module, and the current collector. A booster module that is electrically connected to the electrical unit; at least one second connector that is electrically connected to the booster module; and a wireless transceiver module that is electrically connected to the booster module and the transformer module. Be prepared.

According to a second aspect of the present invention, in the portable power supply device, the first connector in the first aspect is a universal serial bus connector or a micro universal serial bus connector, and the second connector is a universal serial bus. Connector or micro-universal serial bus connector.

  According to a third aspect of the present invention, there is provided a portable power supply device according to the first aspect, wherein the wireless transmission / reception module according to the first aspect is a wireless transmission / reception module capable of receiving or transmitting electrical energy, and is not connected to an electronic device including the wireless transmission / reception module and a secondary battery. This is a transmission / reception module that performs contact charging.

  According to a fourth aspect of the present invention, the portable power supply device further includes a light emitting module that is electrically connected to the booster module.

The power supply device according to the present invention is not only convenient to carry and convenient for use, but also for charging the power supply device itself or charging the electronic product from the power supply device, either a non-contact charging method or a wired method. Can also be selected, which further enhances convenience and practicality in use. Furthermore, by having a simple structure, the service life of the power supply device can be extended, and the production cost can be reduced and the competitiveness of the product in the market can be increased.

It is the block diagram which showed the structure of the portable power supply device by this device. It is explanatory drawing which showed the aspect which charges the portable power supply device disclosed in FIG. 1 by a non-contact charging method. It is explanatory drawing which showed the aspect which charges an electronic product with a non-contact charge system from the portable power supply device disclosed in FIG. It is explanatory drawing which showed the usage condition of the portable power supply device by this invention. It is the block diagram which showed the structure of the portable power supply device by other embodiment.

This device has a non-contact charging method and a wired method, and a portable power supply device that can arbitrarily select a charging method when charging the power supply device itself or charging an electronic product from the power supply device. Providing
In order to describe the structure and characteristics of such a portable power supply device, a specific example will be given and described below with reference to the drawings.

As disclosed in the block diagram of FIG. 1, the portable power supply device according to the present invention includes a first connector 11 in which the power supply device 1 is at least one or more universal serial bus connectors or micro universal serial bus connectors. And at least one or more of a transformer module 12 electrically connected to the first connector 11, a current collecting unit 13 electrically connected to the transformer module 12, and a booster module 14 electrically connected to the current collector unit 13.
