이동통신단말기의 배터리 충전장치{BATTERY CHARGE APPARATUS FOR MOBILE COMMUNICATION TERMINAL}Battery Charger for Mobile Phones {BATTERY CHARGE APPARATUS FOR MOBILE COMMUNICATION TERMINAL}

본 발명은 이동통신단말기의 배터리 충전장칭에 관한 것으로, 특히 태양에너지를 충전하는 충전용 배터리와 단말기를 구동하는 구동용 배터리를 분리하고, 그 구동용 배터리의 배터리의 잔여전압을 항상 감지하여, 일정전압 이하일 경우에 충전용 배터리의 전압을 구동용 배터리에 충전함으로써 안정적으로 단말기에 전원을 공급할 수 있도록 한 이동통신단말기의 배터리 충전장치에 관한 것이다.The present invention relates to a battery charging device of a mobile communication terminal, and in particular, separating a rechargeable battery for charging solar energy and a driving battery for driving the terminal, and always detects the residual voltage of the battery of the driving battery, The present invention relates to a battery charging device of a mobile communication terminal capable of stably supplying power to a terminal by charging a driving battery with a voltage of a rechargeable battery when the voltage is less than the voltage.

일반적으로, 이동통신단말기는,장치의 휴대성(이동성)과 통화의 편리성 때문에 사용이 급증하고 있으며, 무선인터넷접속과 같은 다양한 부가기능이 추가되고 있어서 활용범위가 증가하고 있다.In general, mobile communication terminals are rapidly increasing in use due to the portability (mobility) of devices and convenience of calls, and their range of use is increasing due to the addition of various additional functions such as wireless Internet access.

이러한 휴대성을 위하여 이동통신단말기는 재충전이 가능한 배터리를 교환하여 사용할수 있도록 착탈이 가능한 방식으로 설계, 제조되고 있다.For this portability, the mobile communication terminal is designed and manufactured in a detachable manner so that a rechargeable battery can be used in exchange.

종래 사용되는 배터리는 리튬-이온형이 주로 사용되고 있으며 이동통신단말기 본체의 소형화를 위하여 배터리 본체의 소형화에도 많은 노력을 기울이고 있다.Conventionally, a lithium-ion type battery is mainly used, and much effort has been made to miniaturize the battery main body in order to miniaturize the main body of the mobile communication terminal.

그러나 배터리 본체의 소형화가 진행됨에 따라서 배터리 자체의 충전용량이 감소하기 때문에 사용시간이 단축되는 문제점이 발생된다.However, as the miniaturization of the battery body proceeds, a problem arises that the usage time is shortened because the charging capacity of the battery itself decreases.

더욱이 게임, 무선인터넷과 같은 부가기능이 추가됨에 따라서 핸드폰의 사용시간이 직접 통화보다 부가기능의 실행에 치우치기 때문에 배터리가 거의 소모되어서 실제 통화 시에 용량부족을 겪게 되는 등의 문제점이 있었다.Furthermore, as additional functions such as games and wireless Internet are added, the use time of the mobile phone is more biased to execute the additional functions than direct calls, and thus there is a problem that the battery is almost depleted and the capacity is insufficient during the actual call.

또한 충전용량의 감소로 인하여 자주 재충전된 배터리로 교환하여야 하는 불편함이 있다.In addition, there is an inconvenience to be replaced with a frequently recharged battery due to a decrease in the charging capacity.

이를 해결하기 위하여, 도1과 같이 태양으로부터 방사되는 광을 이용하여 충전할 수 있는 태양열 충전용 판넬(1)을 구비하여, 평상시에는 통상의 충전기를 이용하여 이동통신단말기(3)의 배터리(2)를 충전시키고, 사용중이 아닌 경우에 태양에너지를 이용하여 배터리(2)를 충전을 시킬 수 있는 태양전지를 이용한 충전장치가 구비된 배터리장치가 제공되고 있다.In order to solve this problem, a solar charging panel 1 that can be charged using light emitted from the sun as shown in FIG. 1 is normally used, and the battery 2 of the mobile communication terminal 3 is normally used using a conventional charger. ) And a battery device provided with a charging device using a solar cell capable of charging the battery 2 using solar energy when not in use.

그러나, 이러한 장치는, 실외에서 또는 실내에서 충전기가 없고, 아울러 태양이 없어 태양 에너지를 충전시킬 수 없는 경우에는 안정적으로 전원을 공급하지 못하여, 이동통신단말기를 장기간 사용하게 되면 배터리장치의 잔량전압이 거의 소모되어 이동통신단말기를 사용하지 못하게 되는 문제점이 있다.However, such a device does not have a charger outdoors or indoors, and when the solar energy cannot be charged due to the absence of the sun, the device cannot be stably supplied with power. There is a problem that it is almost consumed and cannot use the mobile communication terminal.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 태양에너지를 충전하는 충전용 배터리와 단말기를 구동하는 구동용 배터리를 분리하고, 그 구동용 배터리의 배터리의 잔여전압을 항상 감지하여, 일정전압 이하일 경우에 충전용 배터리의 전압을 구동용 배터리에 충전함으로써 안정적으로 단말기에 전원을 공급할 수 있도록 한 이동통신단말기의 배터리 충전장치를 제공함에 그 목적이 있다.The present invention has been made in order to solve the above problems, the solar battery is separated from the rechargeable battery for driving the drive battery for driving the terminal, and the residual voltage of the battery of the drive battery to always detect, It is an object of the present invention to provide a battery charging device of a mobile communication terminal that can stably supply power to a terminal by charging a voltage of a rechargeable battery to a driving battery when the voltage is lower than the voltage.
