Description

Rechargeable battery with built-in magnetic charger {RECHARGEABLE BATTERY WITH POWER SELF-GENERATOR MODULE INTEGRATED THEREIN}

The present invention relates to a rechargeable battery with a built-in magnetic charger, and more particularly, a magnetic charger is integrally built into a battery of a personal mobile communication terminal including a mobile phone or a PDA terminal, and thus self-charging of the battery is performed whenever necessary without external power supply. The present invention relates to a rechargeable battery with a built-in magnetic charger.

Recently, with the rapid development of electronic and communication technology, personal mobile communication terminals for mobile communication services that can make calls and communication on the go are widely used. Such personal mobile communication terminals include CDMA terminals, GSM terminals, and PCS terminals. PDA terminals and home radios are representatively included.

In general, a personal mobile communication terminal is essentially provided with a rechargeable battery for supplying the operating power at all times during a call / communication call or communication / communication, and the battery requires a charger for recharging the power.

However, since the battery provided in the personal mobile communication terminal has a characteristic of gradually decreasing its lifespan according to its use period, the frequency of charging by the charger becomes frequent, but the charger usually converts AC power into DC power and then personal mobile communication. It is designed to charge the battery of the terminal, so it is impossible to charge the battery in a place where AC power is not supplied, and it is difficult to carry the charger, and the inconvenience of charging the battery of the personal mobile communication terminal exists. to be.

In view of this, in recent years, various types of battery chargers have been developed and commercialized to facilitate charging of batteries of personal mobile communication terminals. For example, battery charging using a common battery is performed. A typical type of battery charger or a magnetic charger in which a series of gears are rotated by a horizontal force acting in a horizontal direction to supply power generated from a generator motor to a battery of a personal mobile communication terminal is charged.

However, in the battery-type charger, a separate battery is required for charging the battery of the personal mobile communication terminal, which is disadvantageous in terms of economics, and a large amount of waste batteries is generated, which is not very appropriate.

In addition, the magnetic charger is advantageous because the battery of the personal mobile communication terminal is charged with the power generated by itself without using the battery, but it is advantageous because the magnetic force cannot be continuously applied in the horizontal direction. The generator motor rotates to generate power, but during periods when the grip force is not applied, back electromotive force is generated due to the characteristics of the generator motor, so that it is difficult to expect satisfactory charging efficiency. Moreover, the magnetic charger of the personal mobile communication terminal Since it is commercialized in a separate form from the battery, the inconvenience of having to carry the magnetic charger always results.

Accordingly, the present invention has been made in view of the above-described prior art, and has a magnetic charger which charges a rechargeable battery in response to a rotational force continuously applied to the battery so as to maximize charging efficiency and a separate magnetic charger. It is an object of the present invention to provide a rechargeable battery with a built-in magnetic charger, which eliminates the necessity of carrying a battery.

In order to achieve the above object, according to a preferred embodiment of the present invention, in a battery with a built-in rechargeable battery cell, one end of the battery is arranged to be folded in the storage / operating position to provide a rotational force for charging the battery It includes a rotary knob provided, a rotary linking member coupled to the other end of the rotary lever and interlocked with the rotary lever, and a plurality of gears and generator motors coupled to the engaging projection of the rotary linking member to rotate interlockedly. Provided is a rechargeable battery with a built-in magnetic charger, in which a magnetic charging module is integrally installed.

According to the present invention, the magnetic charging module and the battery cell are arranged in a horizontal direction, or the magnetic charging module and the battery cell are arranged in a vertical direction.

In addition, the battery is preferably applied to a personal mobile communication terminal.

The rechargeable battery with a built-in magnetic charger according to the present invention having the above-described configuration, when the rotary knob is continuously rotated, its rotational force is transmitted to the generator motor through a plurality of gears constituting the magnetic charging module through the rotary interlocking member. The motor rotates continuously, and the power generated by the rotation of the generator motor is applied to the rechargeable battery cell of the battery to charge the battery cell.
