Piezoelectric generator for supplying power to portable terminal
A piezoelectric generator for power supply of a portable terminal is provided. The piezoelectric generator includes: a portable terminal case which has a battery mounting part formed on one surface thereof and has parts of the portable terminal mounted therein; a slide part which is formed on opposite side surfaces of a border of the portable terminal case to be able to slide up and down; and a piezoelectric body which has one end or opposite ends connected with the slide part and is disposed in the battery mounting part in a transverse direction, and which vibrates by a sliding movement of the slide part.
1. A piezoelectric generator for power supply of a portable terminal, comprising:
a portable terminal case which has a battery mounting part formed on one surface thereof and has parts of the portable terminal mounted therein, wherein the portable terminal case has a first lateral surface and a second lateral surface opposite to the first lateral surface;
a first slide part on the first lateral surface, wherein the first slide part is configured to slide along the first lateral surface of the portable terminal case;
a second slide part on the second lateral surface, wherein the second slide part is configured to slide along the second lateral surface of the portable terminal case;
a piezoelectric body having a first end and a second end disposed in the battery mounting part in a transverse direction; and
a first connection part connecting the piezoelectric body to an upper surface of the battery mounting part or to an inner part of the portable terminal, wherein the first connection part is configured to transmit a weight of the portable terminal or the inner part of the portable terminal to the piezoelectric body,
wherein the first end of the piezoelectric body is attached to the first slide part or the second end of the piezoelectric body is attached to the second slide part.
2. The piezoelectric generator of claim 1 , further comprising a second connection part which connects the piezoelectric body and a bottom surface of the battery mounting part.
3. The piezoelectric generator of claim 2 , wherein the first connection part and the second connection part are elastic plates, elastic wires, or coil springs.
4. The piezoelectric generator of claim 1 , further comprising an electrode which is formed on at least one surface of the piezoelectric body.
5. The piezoelectric generator of claim 1 , wherein the first slide part protrudes from the first lateral surface of the portable terminal case by a first predetermined distance.
6. The piezoelectric generator of claim 5 , wherein the second slide part protrudes from the second lateral surface of the portable terminal case by a second predetermined distance.
7. A piezoelectric generator for power supply of a portable terminal, comprising:
a portable terminal case which has a battery mounting part formed on one surface thereof and has parts of the portable terminal mounted therein, wherein the portable terminal case has a first lateral surface and a second lateral surface opposite to the first lateral surface;
a slide part having a first slide bar configured to slide along the first lateral surface of the portable terminal case and a second slide bar configured to slide along the second lateral surface of the portable terminal case;
a piezoelectric body having a first end and a second end disposed in the battery mounting part in a transverse direction, and
a first connection part connecting the piezoelectric body to an upper surface of the battery mounting part or to an inner part of the portable terminal, wherein the first connection part is configured to transmit a weight of the portable terminal or the inner part of the portable terminal to the piezoelectric body,
wherein the first end of the piezoelectric body is attached to the first slide bar of the slide part or the second end of the piezoelectric body is attached to the second slide bar of the slide part.
8. The piezoelectric generator of claim 7 , wherein the slide part has an accessory connection part configured to connect to an accessory.
9. The piezoelectric generator of claim 7 , wherein the first slide bar protrudes from the first lateral surface of the portable terminal case by a first predetermined distance.
