Description
본 발명은 휴대 단말기에 관한 것으로서, 메인 배터리의 충전 잔량이 부족할 때 예비되어 있는 배터리를 이용하여 충전 시까지 휴대 단말기에 비상적으로 전원을 공급해 줄 수 있는 백업 배터리를 내장한 휴대 단말기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal, and more particularly, to a portable terminal having a built-in backup battery capable of emergencyly supplying power to a portable terminal until charging using a battery which is reserved when the main battery is low in charge.
일반적으로 휴대 단말기는 3.7V 리튬이온(Li-ion) 배터리를 사용하고 있다. 이 배터리는 충전기를 이용하여 충전되어 휴대 단말기에 계속적으로 전원을 공급할 수 있다. 휴대 단말기에는 배터리의 충전 잔량이 LCD에 표시되어 있으며 휴대 단말기 사용 중 배터리의 충전 잔량이 부족하게 되면 배터리가 부족하다는 메시지를 사용자에게 알려준다. In general, portable terminals use a 3.7V Li-ion battery. The battery can be charged using a charger to continuously supply power to the mobile terminal. In the mobile terminal, the remaining charge of the battery is displayed on the LCD. If the remaining charge of the battery is insufficient while the portable terminal is in use, the user is notified of a low battery.
도 1은 종래의 휴대 단말기의 충전 구조를 나타낸다. 1 shows a charging structure of a conventional portable terminal.
충전기(5)를 통해 배터리(3)를 충전시킬 때 스위치(4)가 레귤레이터(regulator)(2)와 충전기(5)를 연결시키므로 충전과 동시에 MSM(1)에 전원이 공급된다. 배터리(3)의 충전 상태는 MSM(1)의 BATT_ADC 단자에 입력되는 배터리(3)의 전압 레벨에 의해 결정된다. 즉, MSM은 입력된 전압 레벨을 ADC 값(HEX 값)으로 변환하여 단계별 기준에 맞는 배터리바를 LCD에 표시하고 또한 충전기(5)의 LCD 상태를 표시해서 사용자로 하여금 배터리(3)의 충전 상태를 파악할 수 있도록 한다. 배터리(3)의 충전이 완료되어 충전기(5)를 제거하면 스위치(4)는 배터리(3)를 레귤레이터(2)에 연결시켜 이후 배터리(3)가 휴대 단말기에 전원을 공급하게 된다. 스위치(4)의 동작은 MSM(1)의 GPIO 단자에서 나온 신호에 의해 제어된다.When the battery 3 is charged through the charger 5, the switch 4 connects the regulator 2 and the charger 5, so that power is supplied to the MSM 1 at the same time as charging. The state of charge of the battery 3 is determined by the voltage level of the battery 3 input to the BATT_ADC terminal of the MSM 1. That is, the MSM converts the input voltage level into an ADC value (HEX value) to display a battery bar meeting the step-by-step criteria on the LCD, and also to display the LCD state of the charger 5 so that the user can check the state of charge of the battery 3. Make it understandable. When the charging of the battery 3 is completed and the charger 5 is removed, the switch 4 connects the battery 3 to the regulator 2 so that the battery 3 supplies power to the portable terminal. The operation of the switch 4 is controlled by the signal from the GPIO terminal of the MSM 1.
종래의 휴대 단말기를 사용할 때 배터리(3)의 충전 잔량이 부족하더라도 곧바로 충전이 가능한 상황에서는 별 문제가 없겠으나, 일정한 시간 내에 충전을 할 수 없는 상황에서는 휴대 단말기가 자동으로 오프되는 상황이 발생할 수 있기 때문에 사용자에게 불편을 주거나 특히 급한 통화가 필요할 때 사용자를 당황스럽게 할 수 있다. When using a conventional mobile terminal, even if the remaining charge of the battery 3 is insufficient, there is no problem in the situation that can be charged immediately, but in a situation that can not be charged within a certain time the situation that the mobile terminal is automatically turned off may occur. This can be embarrassing for users when they are inconvenient or especially when they need an urgent call.
본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로서, 휴대 단말기에 비상시에 사용할 수 있는 배터리를 내장하여 휴대 단말기의 배터리가 나가더라도 전원이 오프되는 상황 없이 계속해서 휴대 단말기를 사용할 수 있도록 한 백업 배터리를 내장한 휴대 단말기를 제공하는 것을 목적으로 한다. The present invention has been made to solve the above problems, the built-in battery that can be used in an emergency in the mobile terminal, even if the battery of the mobile terminal, even if the power is turned off, the backup can continue to use the mobile terminal An object of the present invention is to provide a portable terminal with a built-in battery.
이를 위해, 본 발명에 의한 백업 배터리를 내장한 휴대 단말기는 그 내부에 백업 배터리를 내장하여, 메인 배터리의 충전 잔량이 부족해지면 상기 메인 배터리 대신에 상기 백업 배터리가 상기 휴대 단말기에 전력을 공급하는 것을 특징으로 한다. To this end, the portable terminal with a built-in backup battery according to the present invention has a built-in backup battery therein, the backup battery to supply power to the portable terminal instead of the main battery when the remaining charge of the main battery is insufficient. It features.
이하, 첨부된 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 의한 백업 배터리를 내장한 휴대 단말기의 충전 구조를 나타낸다. 2 shows a charging structure of a portable terminal incorporating a backup battery according to the present invention.
도 2에서 알 수 있는 바와 같이, 본 발명은 종래의 휴대 단말기와 동일하게 MSM(1), 레귤레이터(2), 배터리(3), 스위치(4) 및 충전기(5)를 비롯하여 비상시 사용되는 백업 배터리(6)를 내장하고 있다. As can be seen in Figure 2, the present invention is a backup battery that is used in emergency, including the MSM (1), regulator (2), battery (3), switch (4) and charger (5) as in the conventional portable terminal (6) is built in.
본 발명에서 충전기(5)를 이용하여 메인 배터리(3)를 충전하게 되면 동시에 백업 배터리(6)도 충전기(5)에 연결되어 함께 충전되도록 구성되어 있다. 그리고 스위치(4)는 레귤레이터(2)와 충전기(5)를 연결하여 충전하는 동안 충전기(5)를 통해 휴대 단말기에 전력이 공급된다. When the main battery 3 is charged using the charger 5 in the present invention, the backup battery 6 is also connected to the charger 5 and configured to be charged together. The switch 4 is supplied with power to the portable terminal through the charger 5 while the regulator 2 and the charger 5 are connected and charged.
충전이 완료되어 충전기(5)를 메인 배터리(3)에서 제거하게 되면 메인 배터리(3)는 레귤레이터(2)와 연결되어 MSM(1)에 전력이 공급됨으로써, 사용자는 메인 배터리(3)의 전원 공급에 의해 휴대 단말기를 사용하게 된다. When the charging is completed and the charger 5 is removed from the main battery 3, the main battery 3 is connected to the regulator 2 to supply power to the MSM 1, so that the user can supply power to the main battery 3. The portable terminal is used by supply.
휴대 단말기의 일정 시간 사용으로 메인 배터리(3)의 충전 잔량이 부족해지면 MSM(1)은 BATT_ADC 단자에 입력되는 메인 배터리(5)의 전압 레벨을 감지하여 그 사실을 인지하고 GPIO 단자를 통해 스위치(4)의 동작을 제어한다.If the remaining charge of the main battery 3 becomes insufficient due to the use of the mobile terminal for a certain period of time, the MSM 1 detects the voltage level of the main battery 5 input to the BATT_ADC terminal and recognizes the fact, and switches it through the GPIO terminal. 4) control the operation.
즉, 메인 배터리(3)의 충전 잔량이 일정한 수치 이하로 떨어지면 MSM(1)은 스위치(4)의 동작을 제어하기 위한 신호를 보낸다. 이 제어신호에 의해 스위치(4)에서 레귤레이터(2)와 메인 배터리(3)와의 연결이 끊어지고 백업 배터리(6)가 레귤레이터(2)와 연결된다. 이에 따라 메인 배터리(5)의 충전 잔량이 부족해지더라도 휴대 단말기는 즉시 백업 배터리(6)의 전력을 공급받을 수 있게 된다. That is, when the remaining charge of the main battery 3 falls below a certain value, the MSM 1 sends a signal for controlling the operation of the switch 4. The control signal disconnects the regulator 2 from the main battery 3 at the switch 4 and the backup battery 6 is connected to the regulator 2. Accordingly, even when the remaining charge of the main battery 5 is insufficient, the portable terminal can immediately receive the power of the backup battery 6.
백업 배터리(6)에 의해 전력이 공급되는 동안에는 휴대 단말기의 LCD에 그 사실이 표시되어 사용자로 하여금 백업 배터리(6)의 충전 잔량이 없어지기 전까지 메인 배터리(3)를 재충전할 수 있도록 주지시켜 준다.While the power is supplied by the backup battery 6, the fact is displayed on the LCD of the portable terminal, which reminds the user to recharge the main battery 3 until the backup battery 6 is no longer charged. .
백업 배터리(6)의 구조는 전자시계나 계산기 등에서 사용되는 원형의 형태를 가질 수 있고, 또한 현재 CDMA 단말기에서는 적용하고 있지는 않지만 GSM 단말기에서 사용되는 SIM 카드와 같은 슬림형의 형태를 가질 수도 있다. 이러한 형태를 갖는 백업 배터리(6)는 휴대 단말기에 삽입 가능하도록 되어 있어서, 사용자는 휴대 단말기로부터 쉽게 백업 배터리(6)를 분리하거나 다른 것으로 교체할 수 있다.The structure of the backup battery 6 may have a circular shape used in an electronic clock, a calculator, or the like, and may also have a slim shape such as a SIM card used in a GSM terminal, although not currently applied in a CDMA terminal. The backup battery 6 having this form is designed to be inserted into the portable terminal so that the user can easily detach the backup battery 6 from the portable terminal or replace it with another one.
상기와 같이 본 발명은 백업 배터리를 내장하여 메인 배터리의 충전 잔량이 부족해지더라도 휴대 단말기의 대기 및 통화시간을 연장시켜줄 수 있는 효과가 있다. As described above, the present invention has an effect of prolonging the standby and talk time of the mobile terminal even when the remaining charge of the main battery is insufficient due to the built-in backup battery.
따라서, 본 발명에 의한 백업 배터리를 내장한 휴대 단말기를 사용하면 휴대 단말기가 저전압 메시지를 알려주어도 충분한 시간 동안 백업 배터리에 의해 휴대 단말기를 사용할 수 있어서 사용자에게 사용상의 여유와 편리함을 줄 수 있다. Therefore, when the portable terminal having the built-in backup battery according to the present invention is used, the portable terminal can be used by the backup battery for a sufficient time even when the portable terminal notifies the low voltage message, thereby providing a user with room for convenience and convenience.
