Description

Dual folder type mobile communication terminal with self-generating charging device {Dualder folder type mobile phone}

The present invention relates to a dual folder type mobile communication terminal, in particular, a dual folder type mobile communication terminal which supplies power to the terminal itself by converting kinetic energy into electrical energy according to the opening and closing operation of the main folder and hinged subfolders. It is about.

In general, the conventional dual folder type mobile communication terminal 1 (DUAL FOLDER TYPE MOBILE PHONE), as shown in Figure 1, the main folder 10 and the subfolder 20 is mechanically rotated by the hinge device "A". Connected as possible.

The hinge device includes a center hinge arm 21 protruding from the lower end of the subfolder 20 and first and second side hinge arms 11a and 11b protruding from the upper left and right sides of the main folder 10 in the same rotation axis. The hinge was combined.

The subfolder 20 has an earpiece 22 disposed below the liquid crystal display 23, and the main folder 10 has a keypad 12 and a microphone 13 disposed below the subfolder 20. On one side of the upper end of the main folder 10, an antenna device (not shown) and a battery pack 30 on the rear side thereof are provided.

The conventional dual folder type mobile communication terminal 1 configured as described above receives and transmits a radio signal with the other party through an antenna device. Accordingly, when a call connection with the other party is made, the user hears the other party's voice through the earpiece 22 and the microphone. Through (13) he conveyed his voice to the other party.

And the call with a specific counterpart is made by the operation of the keypad 12, and by the manipulation of the keypad 12, specific letters and numbers appear on the liquid crystal display 23.

The wireless call function of the terminal 1 is made of energy supplied from the battery pack 30.

The battery pack 30 recharges power to the battery pack 30 using a separate terminal charger (not shown) when the power supply is exhausted according to the continuous use of the terminal 1.

However, the charger does not supply the charging power to the battery pack 30 by generating power by itself, and by supplying the charging power to the battery pack 30 by changing the external power to fit the battery pack 30. It could not be used where there was no external power.

In addition, the charger is a separate product from the terminal 1, there is an inconvenience that must always carry when recharging the battery pack 30.

Therefore, the present invention has been devised in view of such a point, and in particular, it generates power by itself and converts the power according to the specifications of the battery pack so that a charger is not provided or an external power source is not provided in the vicinity. An object of the present invention is to provide a dual folder type mobile communication terminal capable of supplying charging power to a battery pack.

In order to achieve the above object, the present invention is a battery pack coupled to the rear portion and the main folder in which the first and second side hinge arms protrude from the left and right sides at regular intervals from side to side, and the first and second side hinges. A dual folder type mobile communication terminal comprising a subfolder centered between arms and pivoted up and down;

A driving gear formed on the outer circumference of the center hinge arm of the subfolder, a driven gear meshed with the driving gear and rotating in accordance with the operation of the driving gear, and a protruding end of a rotating shaft coupled to the driven gear, A self-powered charging device, characterized in that it comprises a passive generator for generating power in accordance with the rotation operation, and a rectifier for rectifying the power generated by the passive generator into a rated voltage DC power supply to the charging unit of the battery pack. Provided is a dual folder type mobile communication terminal.

If described in detail with reference to Figures 2 and 3 attached to the configuration and embodiment of the present invention.

2 is a rear view of the dual folder type mobile communication terminal according to the present invention, and FIG. 3 is a rear perspective view showing an operating state of the dual folder type mobile communication terminal according to the present invention.

As shown in FIG. 2, the main battery pack 130 is coupled to the rear part and the first and second side hinge arms 121a and 121b protrude from the left and right sides at regular intervals from side to side. 120 and a subfolder 110 in which a center hinge arm 111 is arranged between the first and second side hinge arms 121a and 121b and pivoted up and down, and a center hinge arm of the subfolder 110. A rotary gear 124 formed on the outer circumferential edge of the 111, a driven gear 122 engaged with the driven gear 112 and rotating according to the operation of the driven gear, and the driven gear 122. The generator is coupled to the protruding end of the manual generator 125 and generates power in accordance with the rotation operation of the driven gear 122, and the power generated by the manual generator 125 is rectified to the rated voltage DC power source battery pack 130 It is composed of a rectifier 126 to be supplied to the charging part of the.

In the main folder 120, the driven gear 122, the manual generator 125 and the rectifier 126 are installed internally, and a through hole 123 is formed at the top of the main folder 120 to follow the through hole 123. A portion of the gear 122 is exposed to the upper end of the main folder 120 to engage with the motive gear 112.

The passive generator 125 is a generator having a conventional structure for generating an induction electromotive force on a coil fixed by a permanent magnet (not shown) that rotates together with the rotating shaft 124.

An embodiment of the present invention made as described above will be described in detail with reference to FIGS. 2 and 3.

The operation of the present invention is a subfolder in which the center hinge arm 111 is hinged to the same axis between the first and second side hinge arms 121a and 121b of the main folder 12 in order to use or not use the terminal 100. When the 110 is rotated and opened as shown by arrows "a" and "b", the motive gear 112 formed on the center hinge arm 111 of the subfolder 110 is used to operate the subfolder 110. The driven gear 122 rotated and engaged therewith is rotated, and the rotating shaft 124 of the passive generator 125 in which the driven gear 122 is constructed is rotated to generate power in the passive generator 125.

That is, power is generated in the passive generator 125 according to the opening and closing operation of the subfolder 110.

The power generated by the passive generator 125 is applied to the rectifier 126 is converted into a constant voltage DC power supply according to the specifications of the terminal 100.

In this way, the power converted by the rectifier 126 is output to the battery pack 130 is charged.

As described above, the present invention can increase the power consumption time of the battery pack according to the use of the terminal by providing a self-powered charging device in the terminal to charge the battery pack by the operation of the folder, the external power source Even if it is not supported, the battery pack can be charged by itself. Especially in an emergency, the battery pack can be easily charged to contribute to the user's convenience.
