CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a U.S. National Stage application under 35 U.S.C. § 371 of an International Application number PCT/KR2018/002447, filed on Feb. 28, 2018, which is based on and claimed priority of a Korean patent application No. 10-2017-0027378, filed on Mar. 2, 2017, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

Various embodiments of the present disclosure relate to an apparatus for preventing over-discharge of a battery and an electronic device including the apparatus.

BACKGROUND ART

An electronic device such as a portable terminal, etc., refers to a device that provides an electronic note function such as schedule management, etc., an entertainment function for enjoying multimedia such as music or moving images or a game, and a communication function such as Internet connection, voice communication, etc., and may be used while being carried by a user. Such portable terminals include a built-in or removable battery, thus being provided with power such that the user may use the terminal while carrying the terminal. To make the electronic device elegant in terms of design while improving a waterproof/dustproof effect of the electronic device, an exterior of the electronic device may be formed as one piece and a built-in battery may be used.

DETAILED DESCRIPTION OF THE INVENTION

Technical Problem

When an electronic device including a built-in battery is left for a long time in a power-off state, the built-in battery may be over-discharged. When the built-in battery is over-discharged, swelling of the battery occurs, degrading performance of the built-in battery.

An electronic device according to various embodiments of the present disclosure prevents over-discharge of the battery through blocking an electrical connection between a built-in battery and a circuit board provided with power from the battery, when the battery is not used for a long time.

Technical Solution

An electronic device including an over-discharge preventing apparatus according to various embodiments of the present disclosure includes a housing including a first opening, a first electronic component arranged inside the housing, a second electronic component electrically connected with the first electronic component, and a switch configured to electrically connect the first electronic component with the second electronic component or block an electrical connection between the first electronic component and the second electronic component, by an external force exerted by a pin inserted through the first opening.

An electronic device including an over-discharge preventing apparatus according to various embodiments of the present disclosure may further include a housing including a first face facing a first direction and a second face facing a second direction that is opposite the first direction, the housing further including a first opening formed between the first face and the second face, a battery arranged inside the housing, a circuit board configured to receive power from the battery, and a switch electrically connecting the battery with the circuit board or blocking an electrical connection between the battery and the circuit board, by the external force exerted by the pin inserted through the first opening.

A method for using an electronic device including an over-discharge preventing apparatus according to various embodiments of the present disclosure includes an operation of inserting a pin into a first opening formed in a housing of the electronic device, an operation in which a movable member of a switch arranged between a battery and a circuit board received with power from the battery receives an external force of the pin, an operation in which the movable member is movement-limited by a locking portion, an operation in which the movable member releases a contact between the first terminal and the second terminal, and an operation of blocking an electrical connection between the battery and the circuit board as the contact between the first terminal and the second terminal is released.

Advantageous Effects

An electronic device that prevents over-discharge of a battery according to various embodiments of the present disclosure may selectively block or make an electrical connection between the battery and a circuit board as a switch is pressed by insertion of a pin through a first opening formed in a housing.

The electronic device that prevents over-discharge of the battery according to various embodiments of the present disclosure may improve the waterproof/dustproof effect of the electronic device because of no need for a separate hole by using the first opening formed in the housing.
