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 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 for supplying a main power is separated from the main body;

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

switching terminals configured to connect the power control circuit with the battery for supplying a main power or the auxiliary power supply module;

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

second terminals which are provided in the auxiliary power supply module to be connected therewith, and are configured to, when the battery for supplying a main power is separated from the main body, contact with the switching terminals to connect the auxiliary power supply module with the power control circuit.

2. The device according to claim 1, wherein the switching terminal is formed by bending conductive metal having self-elasticity, is configured to, when the battery for supplying a main power is separated from the main body, be in contact with the second terminal, and

is configured to, when the battery for supplying a main power is connected to the main body, be pressed together with the first terminal by the connection terminal of the battery for supplying a main power so as to deform a shape thereof, and be disconnected from the second terminal.

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

is provided by protruding at a point corresponding to the connection terminal of the battery for supplying a main power, and

is configured to, when being pressed by the connection terminal of the battery for supplying a main power, be pushed inside of the main body so as to contact with the switching terminal.

4. 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.

5. The device according to claim 1, wherein the auxiliary power supply module further comprises a third terminal which contacts with the battery for supplying a main power, and

is configured to receive and store a power from the battery for supplying a main power through the third terminal.

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