Abstract

The present invention provides a portable electronic device having a power maintenance function during replacement of a battery which includes a main body forming an appearance of a portable electronic device, and a battery for supplying a main power which is detachably connected to the main body, and is configured to be charged by an external power and supply the main power to the portable electronic device, wherein the main body includes an auxiliary power supply module, a power control circuit, first terminals connected with switching terminals and the battery for supplying a main power, and second terminals connected with the auxiliary power supply module, such that it is possible to simply and efficiently maintain and control a power supply through a structure of connection terminals even while using a conventional battery contact system.

Claims

1. A portable electronic device having a power maintenance function during replacement of a battery, the portable electronic device comprising:

a main body which forms an appearance of a portable electronic device; and

a battery for supplying a main power which is detachably connected to the main body, and is configured to be charged by an external power and supply the main power to the portable electronic device,

wherein the main body comprises;

an auxiliary power supply module which is fixedly provided inside of the main body, and is configured to supply an auxiliary power to the portable electronic device, when the battery is separated from the main body;

a power control circuit configured to control a power supply to the portable electronic device;

a switching terminal configured to connect the power control circuit with the battery or the auxiliary power supply module;

a first terminal configured to, when the battery is connected to the main body, contact a connection terminal of the battery and the switching terminal to connect the battery with the power control circuit; and

a second terminal which is provided in the auxiliary power supply module to be connected therewith, and is configured to, when the battery is separated from the main body, contact the switching terminal to connect the auxiliary power supply module with the power control circuit, wherein the second terminal is not deformed in a shape when the battery is separated from the main body and when the battery is connected to the main body,

wherein the power control circuit controls the power supply to the portable electronic device when the switching terminal contacts any one of the battery for supplying the main power and the auxiliary power supply module; and

the switching terminal is formed by bending conductive metal having self-elasticity, is configured to, when the battery is separated from the main body, be in contact with the second terminal after being in disconnected with the first terminal, and is configured to, when the battery is connected to the main body, be pressed together with the first terminal by the connection terminal of the battery so as to deform a shape thereof, and be disconnected from the second terminal.

2. The device according to claim 1, wherein the first terminal is formed by bending conductive metal having self-elasticity;

the first terminal is provided by protruding at a point corresponding to the connection terminal of the battery; and

the first terminal is configured to, when being pressed by the connection terminal of the battery, be pushed inside of the main body so as to contact the switching terminal.

3. The device according to claim 1, wherein the second terminal is provided at a point corresponding to the switching terminal, and is formed by bending in an “

L”

shape.

4. The device according to claim 1, wherein the auxiliary power supply module further comprises a third terminal which contacts the battery;

and

the auxiliary power supply module is configured to receive and store a power from the battery through the third terminal.

5. The device according to claim 1, wherein the auxiliary power supply module is to store the power to an extent of maintaining the power-on state of the portable electronic device for 10 to 30 seconds.

6. The device according to claim 1, wherein the first terminal comprises a plurality of the first terminals, the second terminal comprises a plurality of the second terminals, and the switch terminal comprises a plurality of the switch terminals.

7. A portable electronic device comprising:

a battery for supplying a main power to the portable electronic device via a connection terminal; and

a main body to which the battery is detachably connected, the main body comprising;

an auxiliary power supply module provided inside of the main body to supply an auxiliary power to the portable electronic device when the battery is separated from the main body;

a power control circuit to control a power supply to the portable electronic device;

a switching terminal connecting the power control circuit with the battery or the auxiliary power supply module, the switching terminal having self-elasticity;

a first terminal having self-elasticity connected with the battery when the battery is connected to the main body;

a second terminal connected with the auxiliary power supply module when the battery is separated from the main body,

wherein, when the battery is separated from the main body, the first terminal is not in contact with the switching terminal, and the second terminal is in contact with the switching terminal; and

when the battery is connected to the main body, the battery presses the first terminal toward the switching terminal, and the pressed first terminal presses the switching terminal to deform the switching terminal, thereby making the switching terminal be disconnected from the second terminal.

8. The device according to claim 7, wherein the auxiliary power supply module further comprises a third terminal which contacts with the battery;

and

the auxiliary power supply module is configured to receive and store a power from the battery through the third terminal.

9. The device according to claim 7, wherein an end of the switching terminal is bent to form a U shape;

when the battery is separated from the main body, the bent end is in contact with the second terminal; and

when the battery is connected to the main body, the pressed first terminal presses the bent end to make the bent end be not in contact with the end of the second terminal.

10. The device according to claim 7, wherein the second terminal has no elasticity so that the second terminal is not deformed when the battery is separated from the main body, and when the battery is connected with the main body.

11. The device according to claim 7, wherein the first terminal comprises a plurality of the first terminals, the second terminal comprises a plurality of the second terminals, and the switch terminal comprises a plurality of the switch terminals.
