At the present time, it is spreading as an important communication means.

As described above, since the portable terminal is a wireless communication device, a battery, which is a power supply source configured to be freely separated from and coupled to the portable terminal and to be charged, is required.

Hereinafter, a power supply device of a conventional portable terminal will be described with reference to the drawings.

As shown in FIG. 1, the portable terminal is integrally coupled to the main body 10 and one side of the main body 10 by a hinge so that the folder 20 can be opened. On the back, a battery 30 for supplying power is coupled.

As shown in FIG. 2, the other side of the main body unit 10 is provided at the rear surface of the battery coupling surface 11 so as to couple the battery 30 for supplying power required for operation of the mobile terminal.

The battery coupling surface 11 forms a support protrusion 13 having a plurality of fixing grooves 12 at the bottom thereof. Power terminal coupling protrusions (+,-) 14 are formed on both sides of the support protrusion 13, respectively, and are fixed to the fixing grooves 12 so that the battery 30 supported by the support protrusion is engaged. The coupling protrusion 15 and the coupling protrusion 15 for canceling the locking by pushing the coupling protrusion 15 are configured to be supported by the inner elastic member on the upper rear side of the main body 10.

The battery 30 coupled to the battery coupling surface is a plate having a predetermined thickness and a plurality of fixing protrusions corresponding to the fixing groove 12 of the lower end of the main body coupling surface 31 coupled to the battery coupling surface 11 ( 32, and a power supply terminal 33 is formed on the upper surface thereof so as to be in close contact with the power terminal coupling projection 33 to supply power.

In addition, the fixing groove 15 of the main body portion 10 is configured on the upper side so that the defect groove 16 is formed to be fixed to the coupling protrusion 15 after being fixed to the fixing groove 12.

In the conventional portable terminal, only one battery can be mounted in one portable terminal. Therefore, if the rechargeable battery is depleted, the mobile terminal can be utilized only by unconditionally recharging or replacing it with a new one, and when the terminal rechargeable battery is exhausted in an emergency or out of line, information stored in the portable terminal cannot be read or waiting for a call. have.

In order to solve the above problems, the present invention uses two batteries to share a single battery using a battery having a symmetrical shape of the front and the rear, so that the battery is stored in the mobile terminal due to the discharge of the battery during an emergency or when going out. The purpose is to solve the problem of inability to use information and call waiting.

According to the present invention devised to achieve the above object, a dual mode battery having a power terminal in the front and rear, respectively, to supply power by combining two portable terminals; A portable terminal comprising a power terminal coupling protrusion corresponding to the power supply terminal and a coupling means for coupling the dual mode battery to the rear of the main body to receive power from the dual mode battery on the rear of the main body; This is achieved by the dual mode power supply of the terminal.

Hereinafter, the configuration and operation of the dual mode power supply of the portable terminal of the present invention will be described in detail with reference to the accompanying drawings.

3 and 4 are cross-sectional views of a dual mode power supply device of the mobile terminal of the present invention, and FIG.

As shown in FIGS. 3 and 4, the mobile terminals 100 and 200 are integrally coupled by a hinge to allow the folder unit 120 to be opened on one side of the main body unit 110 and the main body unit 110. The dual mode battery 130 for supplying power is coupled to the rear surface of the main body unit 110, and the main body portions of the portable terminal are coupled to the front and rear surfaces of the dual mode battery, respectively.

The portable terminal 100, 200 is a portable terminal that can be used by sharing the dual-mode power supply, and the description and the description of the same structure and function are omitted.

On the other side of the main body 110, the battery engaging surface 111 is provided on the rear surface to be coupled to one surface of the dual-mode battery 130 for supplying power required for operation of the mobile terminal.
