The present invention relates to a mobile phone battery equipped with a contactless smart card chip configured to perform functions such as subway fare payment.

As the entry into the credit society accelerates, the use of credit cards such as smart cards is increasing. These credit cards are mainly developed from cards using magnetic strips, and are mainly composed of contactless smart cards that transmit and receive data wirelessly. On the other hand, the use of mobile phones (or mobile phones) has also exploded, becoming a necessity for everyday people to carry, and products combining mobile phones and smart cards are being used on the market. The combination of mobile phone and smart card provides convenience to users by increasing the portability and convenience of the products that have been established as daily necessities.

1 is a separation state diagram of a conventionally used mobile phone, the mobile phone is separated into a main body 10 and the battery 20 for supplying power to the mobile phone. The main body 10 is equipped with an LCD display window, an antenna, a microphone, a speaker, a keypad, etc., and performs all functions. The battery 20 is equipped with electrodes for recharging, detachable, and supplies only power for operation. have. When the battery 20 is exhausted, the user detaches the battery 20 and charges it using a charger, and then installs the battery 20 again.

A smart IC chip is mounted on a conventional mobile phone as described above and used with a smart card. 2 shows the installation state of the smart IC chip 16, and shows the back of the mobile phone main body 10 for mounting the battery 20.

After the IC chip 16 is mounted as described above, the battery 20 is coupled. In use, the mobile phone is used within 10 cm of the smart card reader in the same direction as the conventional smart card.

However, the method of embedding the IC chip in the mobile phone as described above has a disadvantage in that it increases the manufacturing cost of the mobile phone because it must be applied to each mobile phone model from the initial design stage of the mobile phone. In addition, since different IC chip specifications are applied to each manufacturer, IC chip compatibility is difficult and there is a problem of fundamentally restricting participation of general smart card manufacturers, not mobile phone manufacturers. In addition, when a cell phone malfunction occurs, the smart card function is also stopped at the same time, causing inconvenience in use.

The present invention is to solve the above problems, an object of the present invention is to provide a smart IC chip module capable of inputting and outputting data in a non-contact manner to a conventional battery for mobile phones, mobile e-commerce, debit transactions, bus or subway fare payment To provide a cell phone battery with a contactless smart card chip configured to perform such functions.

Another object of the present invention is to operate a credit card function even when a cell phone failure occurs even when used in a mobile phone is equipped with a non-contact smart card chip is easy to replace the smart IC chip To provide a battery.

As shown, the inner cover 32 having the electrode 36 exposed to the outside, the battery pack 34 charged with the operating power, and the separator to block the contact with the battery pack 34 ( 38), an electromagnetic shielding plate 40 for blocking electromagnetic waves, and an outer cover 46 of the battery provided with an electrode 36a.

The outer cover 46 has a chip module receiving groove 44 formed at a predetermined depth, and the smart IC chip module 42 is mounted therein. When the smart IC chip module 42 receives a radio frequency signal of a specific frequency band from the outside in a non-contact manner, the smart IC chip module 42 is used to generate a power required for operation to record / read data and transmit a signal. The structure of the smart IC chip module 42 is described later.

The smart IC chip module 42 performing contactless data communication is mounted on the outer cover 46 which is exposed to the outside when mounted on the mobile phone for accurate operation. In addition, the electromagnetic shielding plate 40 is mounted in close contact with the smart IC chip module 42 in order to prevent the influence of the internal device of the mobile phone and to block the influence from the mobile phone when the smart IC chip module 42 is operated. do.

The electromagnetic shielding plate 40 may be formed using a shielding material having a function of coating an electromagnetic shielding paint on the surface of the PET film or reflecting or absorbing electromagnetic waves. In addition, instead of using the electromagnetic wave shielding plate 40, it can be configured by coating a coating having an electromagnetic wave blocking function on the back surface is not formed the antenna of the board.

The separator 38 is intended to block direct contact between the electromagnetic shielding plate 40 and the battery pack 34, and may be configured using a conventional PET material.
