Description

알에프아이디 안테나 내장형 배터리팩{battery pack with a built-in RFID antenna}Battery pack with a built-in RFID antenna}

본 발명은 무선주파수 식별(Radio Frequency Identification, RFID) 안테나를 내장한 배터리팩에 관한 것으로, 보다 구체적으로는 배터리셀과 RFID 안테나 사이에 소제(flex-suppressor)를 설치하여 RFID 안테나의 수신감도를 높이고 소형화, 슬림화를 달성한 배터리팩에 관한 것이다.The present invention relates to a battery pack having a built-in radio frequency identification (RFID) antenna. More particularly, a flex-suppressor is installed between the battery cell and the RFID antenna to increase reception sensitivity of the RFID antenna. The present invention relates to a battery pack that has achieved miniaturization and slimness.

최근 정보화의 급속한 발달로 각종 상품이나 서비스에 대한 요금지불수단도 현금으로부터 신용카드, 전자화폐 등으로 급속하게 옮겨져 가고 있다. 이러한 추세에 따라 보다 간편하고 손쉽게 상품이나 서비스에 대한 비용결재를 하기 위한 다양한 연구가 이루어지고 있다. 특히, 사용자 정보를 저장하고 금액충전이 가능한 비접촉식 전자칩을 무선통신 단말기에 내장하고, 그 전자칩에 저주파 유도기전력을 형성시키기 위해 무선통신 단말기의 배터리에 루프 안테나를 내장하여 사용 및 금액충전을 편리하게 할 수 있는 비접촉식 전자칩이 내장된 무선통신 단말기가 개발되었다.Recently, with the rapid development of informatization, payment methods for various goods and services are also rapidly shifted from cash to credit cards and electronic money. According to this trend, various researches are being conducted to make payment of goods or services more easily and easily. In particular, a non-contact electronic chip that stores user information and charges money is embedded in a wireless communication terminal, and a loop antenna is built in the battery of the wireless communication terminal to form a low frequency induction electromotive force on the electronic chip for convenient use and money charging. A wireless communication terminal with a built-in contactless electronic chip has been developed.

도 1은 배터리셀 주변에 루프형 안테나를 배치한 종래의 RFID 안테나 내장형 배터리팩을 도시한 평면도이다. 도 1에서 10은 이동통신 단말기 본체에 착탈가능하도록 구성되는 배터리팩을 나타낸다. 배터리팩(10)은 단말기 본체(도시생략)에 공급할 전력을 충전 및 방전하기 위한 배터리셀(12)과, 배터리셀(12)의 바깥 둘레에 나선형으로 수회 권선되어 이동통신 단말기를 카드 판독기에 근접시킴에 따라 카드 판독기와 통신가능하도록 유도기전력을 형성하는 루프 안테나(14)를 구비한다. 한편, 배터리팩(10)에는 배터리셀(12)로부터 전력을 단말기 본체로 공급하기 위한 전원단자(18)와 루프 안테나(14)를 단말기 본체의 전자칩(도시생략)에 연결하기 위한 안테나 연결단자(16)가 구비된다.1 is a plan view illustrating a conventional RFID antenna built-in battery pack in which a loop antenna is disposed around a battery cell. 1 to 10 show a battery pack configured to be detachable from a mobile communication terminal body. The battery pack 10 is a battery cell 12 for charging and discharging the power to be supplied to the terminal body (not shown), and spirally wound around the outer circumference of the battery cell 12 to close the mobile communication terminal to the card reader. And a loop antenna 14 which forms an induced electromotive force so as to be in communication with the card reader. On the other hand, the battery pack 10 has an antenna connection terminal for connecting the power supply terminal 18 and the loop antenna 14 for supplying power from the battery cell 12 to the terminal body to an electronic chip (not shown) of the terminal body. 16 is provided.

이러한 구성을 갖는 배터리팩(10)을 단말기 본체에 결합한 후, 사용자가 판독기(도시생략)에 접근시키면 배터리팩(10)에 내장된 루프 안테나(14)의 유도기전력에 의해 단말기 본체의 전자칩이 기동하게 되어 상품이나 서비스에 대한 전자결재가 이루어지게 된다. 여기에서 전자결재가 이루어지는 구체적인 과정은 본 발명의 본질적인 부분이 아니기 때문에 설명의 간략화를 위해 본 명세서에서는 그에 대하여는 상세히 설명하지 않는다.After the battery pack 10 having such a configuration is coupled to the terminal body, when the user approaches the reader (not shown), the electronic chip of the terminal body is induced by the induced electromotive force of the loop antenna 14 built in the battery pack 10. It is activated to make an electronic payment for goods or services. Since the specific process in which the electronic payment is made here is not an essential part of the present invention, for the sake of simplicity, the specification is not described in detail herein.

그러나 상기와 같은 배터리팩의 구성에서는 배터리셀(12)의 외주변을 따라 RFID 안테나를 나선형으로 수회 권선하여 형성함으로써 배터리팩의 크기가 커지는 문제점이 있었다. 즉 배터리셀 외주변에 RFID 안테나를 수회 권선함으로써 그 RFID 안테나가 차지하는 면적만큼 배터리팩의 면적이 증가하게 되고, 이는 전체 단말기의 외형적 크기를 증가시켜 휴대용으로 사용하는 이동통신 단말기의 본래 목적을 위해서는 매우 불리한 점이 있었다.However, in the configuration of the battery pack as described above, there is a problem that the size of the battery pack is increased by forming the RFID antenna spirally wound several times along the outer periphery of the battery cell 12. That is, by winding the RFID antenna around the battery cell several times, the area of the battery pack is increased by the area occupied by the RFID antenna, which is to increase the external size of the entire terminal and to achieve the original purpose of the mobile communication terminal. There was a very disadvantage.

한편, 이와 같이 배터리팩의 외형이 커지는 문제점을 해소하기 위해, 배터리셀과 RFID 안테나를 상하로 적층하여 배터리팩을 형성하는 방법을 생각해 볼 수 있으나 이 경우에도 두께가 매우 두꺼워지는 문제점이 존재한다. 즉, 적층형으로 구성할 경우에는, 배터리셀의 외부 케이스가 보통 도체로 형성되어 있으므로 RF 카드 판독기(RF card reader)에서 출력되는 전파가 도체케이스에 흡수되어버려 RFID 안테나에 기전력 및 통신신호가 유도될 수 없게 된다. 따라서 이러한 방해요소를 제거하기 위해서는 RFID 안테나와 배터리셀 사이의 간격을 되도록 크게 형성할 수 밖에 없다. 그러나 배터리셀과 RFID 안테나 사이의 간격을 크게 하면 통신감도나 성능은 개선되지만 이동통신 단말기의 소형화, 슬림화라는 추세에는 역행하게 된다.On the other hand, in order to solve the problem that the appearance of the battery pack is increased, it is possible to think of a method of forming a battery pack by stacking the battery cells and the RFID antenna up and down, but there is also a problem that the thickness is very thick. That is, in the case of the stack type, since the outer case of the battery cell is usually formed of a conductor, the electric wave output from the RF card reader is absorbed by the conductor case, so that electromotive force and communication signal can be induced to the RFID antenna. It becomes impossible. Therefore, in order to remove such obstacles, the distance between the RFID antenna and the battery cell can only be formed as large as possible. However, increasing the distance between the battery cell and the RFID antenna improves communication sensitivity and performance, but counters the trend of miniaturization and slimming of mobile communication terminals.

따라서 본 발명의 목적은 상기한 문제점을 해소하여 소형화, 슬림화에 문제를 발생시키지 않으면서도 통신감도나 성능을 저하시키지 않는 RFID 안테나 내장형 배터리팩을 제공하기 위한 것이다.Accordingly, an object of the present invention is to solve the above problems and to provide a battery pack with a built-in RFID antenna that does not reduce communication sensitivity or performance without causing problems in miniaturization and slimming.

도 2에서, 100은 단말장치 본체에 착탈가능하게 구성되는 배터리팩을 나타낸다. 배터리팩(100)은 단말기 본체에 공급할 전력을 충전 및 방전하며 전원단자를 구비한 배터리셀(110)과, 이 배터리셀(110)의 상부에 배치되어 수십 MHz∼수 GHz의 전파 및 노이즈를 제거하는 소제(Flex-suppressor)(120)와, 소제(120)의 상부에 배치되어 RF 판독기(도시생략)로부터의 전원에 의해 유도기전력을 유도받아 판독기와 무선통신을 할 수 있는 RFID 안테나(130)를 포함한다. 배터리팩(100)에 형성되는 RFID 안테나(130)는 루프형 안테나 또는 마이크로 스트립 라인 안테나(micro strip line antenna)인 것이 바람직하다.In FIG. 2, 100 represents a battery pack detachably mounted to a terminal device body.

상술한 본 발명의 바람직한 실시예는 단지 예시의 목적을 위한 것이며, 후술하는 특허청구범위에 기재된 본 발명의 사상과 범위로부터 벗어나지 않고 그 구성요소와, 그 조합 및 배열에 대하여 변경이 행해진 것은 모두 첨부된 특허청구범위에 표현된 내용에 포함되는 것으로 이해되어야 한다.Preferred embodiments of the present invention described above are for illustrative purposes only, and all modifications to the components, combinations and arrangements thereof are attached without departing from the spirit and scope of the invention as set forth in the claims below. It should be understood that it is included in the contents expressed in the claims.

상술한 바와 같이 본 발명의 실시예에 따르는 RFID 내장형 배터리팩의 구성에 의하면 배터리셀(110)과 RFID 안테나(130) 사이에 소제(120)가 형성되므로 판독기(RFID card reader)에서 출력되는 전파가 소제(120)에 의해 차단되어 배터리셀(110)에 흡수되지 않게 된다. 따라서 RFID 안테나(130)에는 기전력 및 통신신호가 유도되게 되어 통신감도나 성능에 대한 저하가 발생하지 않게 된다. 결국 종래의 배터리팩에 비해 소형화, 슬림화의 목적을 달성하면서 성능상의 저하가 없는 우수한 배터리팩을 얻을 수 있게 된다.As described above, according to the configuration of the RFID built-in battery pack according to the embodiment of the present invention, since the sweeping 120 is formed between the battery cell 110 and the RFID antenna 130, a radio wave output from the RFID card reader is generated. Blocked by the cleaning agent 120 is not absorbed by the battery cell 110. Therefore, the electromotive force and the communication signal are induced in the RFID antenna 130 so that the degradation of the communication sensitivity or the performance does not occur. As a result, it is possible to obtain an excellent battery pack without deterioration in performance while achieving the purpose of miniaturization and slimness compared to the conventional battery pack.
