본 발명의 다른 목적, 특징 및 이점들은 첨부한 도면을 참조한 실시예들의 상세한 설명을 통해 명백해질 것이다.Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

이하, 첨부된 도면을 참조하여 본 발명의 실시예의 구성과 그 작용을 설명하며, 도면에 도시되고 또 이것에 의해서 설명되는 본 발명의 구성과 작용은 적어도 하나의 실시예로서 설명되는 것이며, 이것에 의해서 상기한 본 발명의 기술적 사상과 그 핵심 구성 및 작용이 제한되지는 않는다.Hereinafter, with reference to the accompanying drawings illustrating the configuration and operation of the embodiment of the present invention, the configuration and operation of the present invention shown in the drawings and described by it will be described as at least one embodiment, By the technical spirit of the present invention described above and its core configuration and operation is not limited.

도 1은 본 발명의 일 실시예에 따른 배터리팩을 나타낸 도면이다.1 is a view showing a battery pack according to an embodiment of the present invention.

배터리팩(100)은 외부 케이스(101)와, 그 외부 케이스(101)내에 배치되는 배 터리 셀(102)과, 상기 외부 케이스(101)와 배터리 셀(102) 사이에 구성되어 휴대폰 통화시 발생되는 열이 외부로 빠져나가지 않게 하는 보온재(103)를 포함한다.The battery pack 100 is configured between an outer case 101, a battery cell 102 disposed in the outer case 101, and the outer case 101 and the battery cell 102 to generate a mobile phone call. It includes a heat insulating material 103 to prevent the heat to escape to the outside.

상기 보온재(103)가 외부 케이스(101)와 배터리 셀(102) 사이에 들어갈 수 있도록 보온재(103)와 외부 케이스(101) 사이에 외벽을 구성하고 보온재(103)와 배터리 셀(102) 사이에 내벽을 구성한다.An outer wall is formed between the heat insulating material 103 and the outer case 101 to allow the heat insulating material 103 to enter between the outer case 101 and the battery cell 102, and between the heat insulating material 103 and the battery cell 102. Make up the inner wall.

따라서, 상기 보온재(103)에 의한 보온효과에 의해 통화시 발생되는 열이 외부로 빠져나가지 않고 유지되므로 외부의 낮은 온도에 의한 배터리팩(100)의 온도 저하를 어느 정도 막을 수 있으므로 저온에서의 핸드폰 통화시간을 늘릴 수 있다.Therefore, since the heat generated during the call is maintained without escaping to the outside due to the thermal insulation effect by the thermal insulation material 103, the temperature drop of the battery pack 100 due to the external low temperature can be prevented to some extent, so that the mobile phone at low temperature Increase talk time

도 2는 본 발명의 다른 실시예에 따른 배터리팩을 나타낸 도면으로, 상기 일 실시예에 따른 배터리팩(100)의 구성에 주변 온도가 일정치 이하인 경우에 구동되는 발열부(104)를 추가하였다.2 is a view showing a battery pack according to another embodiment of the present invention, the heating unit 104 is added to the configuration of the battery pack 100 according to an embodiment when the ambient temperature is below a certain value. .

즉, 외부 케이스(101)와, 그 외부 케이스(101)내에 배치된 배터리 셀(102)과, 상기 외부 케이스(101)와 배터리 셀(102) 사이에 구성되어 휴대폰 통화시 발생되는 열이 외부로 빠져나가지 않도록 하는 보온재(103) 이외에 주변 온도가 일정치 보다 낮아지는 경우에 구동되어 열을 방출하는 발열부(104)로 구성된다.That is, the heat is generated between the outer case 101, the battery cell 102 disposed in the outer case 101, and the outer case 101 and the battery cell 102 to generate a mobile phone call to the outside. In addition to the thermal insulation material 103 to prevent escape, it is composed of a heat generating portion 104 is driven when the ambient temperature is lower than a predetermined value to release heat.

상기 발열부(104)는 배터리 셀(102)과 보온재(103) 사이에 구성하는 것이 바람직하다.The heat generating unit 104 is preferably configured between the battery cell 102 and the heat insulating material (103).

배터리팩이 장착되는 휴대폰 본체에 외부 온도를 체크하는 온도 센서부(200)와 측정한 온도가 일정치 이하인 경우에 상기 발열부(104)를 구동시키는 발열부 구동 회로(300)를 구비하여 상기 온도 센서부(200)가 감지한 온도가 일정치 이하이면 상기 발열부 구동 회로(300)의 동작이 개시되어 발열(104)를 구동시킨다.The mobile phone body on which the battery pack is mounted is provided with a temperature sensor unit 200 for checking an external temperature and a heating unit driving circuit 300 for driving the heating unit 104 when the measured temperature is equal to or less than a predetermined value. When the temperature detected by the sensor unit 200 is lower than or equal to a predetermined value, the operation of the heating unit driving circuit 300 is started to drive the heating unit 104.

본 실시예에서는 보온재(103)뿐만 아니라 발열부(104)도 함께 구성하고 있기 때문에 배터리팩(100)의 온도를 보다 빠르고 효과적으로 올릴 수 있다. In this embodiment, since the heat generator 104 is configured as well as the heat insulating material 103, the temperature of the battery pack 100 can be raised more quickly and effectively.

또한, 상기 발열부(104)에서 잠깐동안만 온도를 올려 주어도 보온재(103)에 의한 보온효과와 핸드폰 통화중 발열로 배터리팩(100)의 온도를 상온으로 유지시킬 수 있으므로 장시간의 통화가 가능하다.In addition, even if the temperature is raised only for a short time in the heat generating unit 104, the heat insulation effect by the heat insulating material 103 and the heat generated during the phone call can maintain the temperature of the battery pack 100 at room temperature, so long-term communication is possible. .

상기와 같은 본 발명의 휴대폰의 배터리팩은 다음과 같은 효과가 있다.The battery pack of the mobile phone of the present invention as described above has the following effects.

보온재에 의한 보온 효과에 의해 통화시 발생되는 열이 보존되며 발열부를 통해 열을 공급할 수 있어 저온의 분위기에서도 배터리팩의 온도를 상온 수준으로 만들 수 있으므로 저온상태에서 휴대폰의 장시간 통화가 가능한 효과가 있다.The heat generated during the call is preserved by the insulation effect by the heat insulating material, and heat can be supplied through the heat generating part so that the temperature of the battery pack can be made at room temperature even in a low temperature atmosphere. .

이상 설명한 내용을 통해 당업자라면 본 발명의 기술 사상을 이탈하지 아니하는 범위에서 다양한 변경 및 수정이 가능함을 알 수 있을 것이다.Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

따라서, 본 발명의 기술적 범위는 실시예에 기재된 내용으로 한정하는 것이 아니라 특허 청구범위에 의해서 정해져야 한다.Therefore, the technical scope of the present invention should not be limited to the contents described in the examples, but should be defined by the claims.
