The sliding hinge 300 is connected to the slider 200 so as to be slidably movable with respect to the main body 100, and includes a fixed plate 310 and a sliding plate 320.

Here, the fixing plate 310 is fixed to the main body 100, the sliding plate 320 is fixed to the slider 200 and coupled to the fixed plate 310 to enable a linear reciprocating motion. Accordingly, the slider 200 may be slidably moved with respect to the main body 100 according to the linear movement of the sliding plate 320.

The sliding hinge 300 is equipped with an elastic member such as a spring such that the sliding plate 320 is compressed when the sliding plate 320 is moved to a certain extent, and is tensioned when the moving plate is over the set limit, so that the sliding plate 320 automatically slides. . In addition, the magnet member may be mounted to automatically move the sliding plate 320 by the force of the magnet.

On the other hand, as shown in Figure 2, the mobile phone battery self-charging device according to an embodiment of the present invention includes a piezoelectric element 400, the conversion coil 500, the battery 110 and the diode 600. .

In general, a piezoelectric element refers to a semiconductor device that generates electromotive force by an applied pressure or an impact. When an external force is applied to a crystal plate on one side in a predetermined direction, positive and negative charges are proportional to the external force at both ends of the crystal plate. Will occur.

The piezoelectric element 400 according to the present invention refers to any type of semiconductor element capable of generating electromotive force by impact or pressure. As shown in FIG. 2, the keypad 111 provided in the main body 100 is provided. It is attached to the bottom that is not exposed to the outside of).

In addition, the piezoelectric elements 400 may be attached to a plurality of positions at positions corresponding to letters, numbers, and symbols on the keypad 111, respectively.

That is, when the user enters a phone number on the keypad 111 for a mobile phone call or inputs a message for text transmission, pressure is applied to the piezoelectric element 400, thereby causing the piezoelectric element. EMF is generated.

Meanwhile, two first and second power lines 710 and 720 are connected to the plurality of piezoelectric elements 400, respectively, and have positive and negative polarities.
