Description

휴대 단말기용 무선 충전 배터리{Wireless recharge bettery of mobile terminal}Wireless charging battery for mobile terminal {Wireless recharge bettery of mobile terminal}

본 발명은 휴대 단말기용 무선 충전 배터리에 관한 것으로서, 더욱 상세하게는, 수신측 2차코일을 배터리의 측면에 설치하여 배터리 두께 증가없이 무선 충전 배터리를 제공하는 휴대 단말기용 무선 충전 배터리에 관한 것이다.
The present invention relates to a wireless rechargeable battery for a mobile terminal, and more particularly, to a wireless rechargeable battery for a mobile terminal by providing a secondary rechargeable coil on the side of the battery to provide a wireless rechargeable battery without increasing battery thickness.

일반적으로 휴대 단말기 예를 들어, 휴대폰, 휴대용 게임기, 휴대용 멀티미디어 재생기 등은 전원 공급을 위해 착탈식 배터리를 이용하며, 배터리는 보편적으로 충전식 배터리를 사용한다.In general, a mobile terminal such as a mobile phone, a portable game machine, a portable multimedia player, and the like use a removable battery for power supply, and the battery generally uses a rechargeable battery.

배터리를 충전하기 위해서는 일반 전원과 연결되어 이동 단말기의 배터리에 전기 에너지를 공급하기 위한 충전유닛(또는 충전모체, 충전장치)이 필요하다. 상기 충전 유닛과 배터리에는 외부에 각각 별도의 접촉단자가 구성되어 있어, 두 접촉단자를 서로 접속시켜 선택적으로 배터리를 충전할 수 있도록 되어 있다.In order to charge the battery, a charging unit (or charging mother, charging device) for supplying electrical energy to the battery of the mobile terminal connected to the general power source is required. The charging unit and the battery are provided with separate contact terminals, respectively, so that the two contact terminals can be connected to each other to selectively charge the battery.

그러나, 휴대 단말기의 종류나 타입별로 배터리의 사이즈나 접촉단자의 형태등이 다를 수 있고, 배터리 또는 휴대 단말기를 거치시키는 거치대의 형태나 규격도 다를 수 있으므로, 각각의 휴대 단말기마다 각각의 충전장치를 별도로 제공하고 있다.However, since the type or type of the mobile terminal may vary in the size of the battery or the type of the contact terminal, and the shape or size of the cradle for mounting the battery or the mobile terminal may also vary, Provided separately.

이러한 종래의 문제점을 개선하고자 무선 충전 즉, 무접전 충전장치들이 적용된 휴대 단말기가 출시되고 있다. 무접점 충전방식은 충전유닛에 1차코일(자계발생코일)을 구비하고 단말기와 같은 충전 대상에 2차코일(유도코일)을 구비하여, 상기 단말기가 충전 유닛에 접근할 경우 상기 1차코일과 2차코일간의 유도결합에 의해 단말기를 충전하는 방식이다.In order to improve such a conventional problem, a portable terminal using wireless charging, that is, a contactless charging device has been released. The contactless charging method includes a primary coil (magnetic field generating coil) in a charging unit and a secondary coil (induction coil) in a charging target such as a terminal, and when the terminal approaches the charging unit, The method of charging the terminal by inductive coupling of the second co-day.

이와 같은 종래의 무접점 충전방식은, 충전기에 1차 코일을 설치하여 송전장치를 구성하고, 휴대 단말기에 2차 코일을 설치하여 수전장치를 구성하여 무선으로 휴대장치의 내장 배터리를 충전하는데, 휴대 단말기의 배터리 또는 배터리 케이스에 2차 코일을 설치하여 수전장치를 구성하는 방식이다.In the conventional contactless charging method, a primary coil is installed in a charger to configure a power transmission device, and a secondary coil is installed in a portable terminal to configure a power receiver to wirelessly charge the internal battery of the portable device. A power receiver is constructed by installing a secondary coil on a battery or a battery case of a terminal.

그런데, 휴대폰과 같은 휴대 단말기에서는 두께를 줄이고자하는 노력을 기울이고 있기 때문에 2차 코일을 휴대 단말기 본체 또는 휴대 단말기 배터리 케이스에 내장하여 설치하는 경우, 착탈식 배터리와 연결되는 연결 접점을 필요로 하며, 배터리를 장착한 상태에서 휴대 단말기 자체를 무선 충전기에 올려놓아야 한다는 단점이 있다.However, since efforts are made to reduce the thickness of a portable terminal such as a mobile phone, when the secondary coil is installed in the portable terminal body or the portable terminal battery case, a connection contact connected to the detachable battery is required. The wireless terminal itself must be placed on the wireless charger.

한편, 휴대 단말기의 배터리의 상면 또는 하면에 2차코일을 설치할 수도 있는데, 최근 들어 휴대폰에는 근거리 무선통신을 위한 루프코일 안테나(MFC 코일)가 배터리 표면에 설치되어 있기 때문에 무선 충전을 위한 2차 코일을 배터리에 더 설치하는 경우 배터리 두께가 두꺼워진다는 단점을 피할 수 없다. 휴대폰과 같은 휴대 단말기에서는 박형화(두께가 얇은 단말기)에 많은 노력을 기울이고 있으므로, 배터리의 두께가 두꺼워진다는 것은 휴대폰의 박형화에 위배 된다는 단점을 가진다.
선행기술문헌 : 한국공개특허공보 제10-2012-0008628호(2012.02.01.)On the other hand, the secondary coil may be installed on the upper or lower surface of the battery of the mobile terminal. Recently, the secondary coil for wireless charging has been installed in the mobile phone because the loop coil antenna (MFC coil) for short range wireless communication is installed on the battery surface. If you install more on the battery, the disadvantage of thickening the battery is inevitable. In a portable terminal such as a mobile phone, since much effort is made on thinning (thin thickness terminal), the thickening of the battery has a disadvantage of violating the thinning of the mobile phone.
