본 발명은 이동식 안테나구조를 갖는 이동통신단말기에 관한 것으로, 특히 슬라이딩 커버부가 오픈될 경우 래크와 피니언기어의 운동에 따라 안테나도 이동되 어 몸체부와 수직된 방향으로 자동으로 돌출되는 이동식 안테나구조를 갖는 이동통신단말기에 관한 것이다.The present invention relates to a mobile communication terminal having a mobile antenna structure, and in particular, when the sliding cover is opened, the antenna is also moved according to the motion of the rack and pinion gear so that the mobile antenna structure is automatically projected in a direction perpendicular to the body portion. It relates to a mobile communication terminal having.

일반적으로 무선 데이터 통신(wireless data communication)은 이동중인 사람이 무선 송수신이 가능한 휴대형 단말기를 이용하여 문자, 숫자, 영상 등 각종 데이터를 무선으로 주고 받는 통신기능을 말한다. 즉, 셀룰러폰, 휴대용 컴퓨터, 팩시밀리, 신용카드 조회기등 각종 단말기를 이용하여 이동중에 양방향으로 자료를 교환하거나 검색하는 이동 통신체계이다. 그런데, 이러한 무선 테이터 통신은 크게 전용 패킷망, 셀룰러, PCS, TRS, 그리고 CT-2 등의 무선 통신망을 통하여 이루어지게 되는데, 이때 최근에 제조되는 상기와 같은 이동통신단말기들은 다양한 구조 예컨대, 폴더형이나 혹은 슬라이드 업(Slide-up)형태의 구조로 이루어진다.In general, wireless data communication refers to a communication function of wirelessly transmitting and receiving various data such as letters, numbers, and images by using a portable terminal capable of wireless transmission and reception. That is, a mobile communication system that exchanges or retrieves data in both directions while moving by using various terminals such as a cellular phone, a portable computer, a facsimile, and a credit card inquiry machine. By the way, such wireless data communication is largely made through a wireless communication network such as a dedicated packet network, cellular, PCS, TRS, and CT-2, wherein the recently manufactured mobile communication terminals have various structures, Or it consists of a slide-up (Slide-up) structure.

그러면, 상기와 같은 종래 슬라이드 업형 이동통신단말기를 도 1을 참고로 살펴보면, 상하로 슬라이딩되면서 몸체의 상면에 LCD패널(70)이 설치되는 슬라이딩 커버부(71)와, 상기 슬라이딩 커버부(71)가 상하로 슬라이딩 되도록 양측에 레일(72)이 구비된 몸체부(73)와, 상기 몸체부(73)의 일측에 설치되어 RF신호를 송수신처리하는 안테나(74)를 포함한다. Then, referring to the conventional slide-up mobile communication terminal as described above with reference to FIG. 1, the sliding cover part 71 in which the LCD panel 70 is installed on the upper surface of the body while sliding up and down, and the sliding cover part 71. It includes a body portion 73 is provided with a rail 72 on both sides so as to slide up and down, and an antenna 74 is installed on one side of the body portion 73 for transmitting and receiving RF signals.

여기서, 상기 안테나(74)는 통상 헬리컬 안테나와 모노폴(MONOPOLE) 안테나가 사용된다. 그리고, 상기 슬라이딩 커버부(71) 혹은 몸체부(73)의 일측에는 사용자의 기능설정신호를 입력시키는 키패드(75)가 구비된다. Here, the antenna 74 is typically used a helical antenna and a monopole antenna. In addition, one side of the sliding cover 71 or the body portion 73 is provided with a keypad 75 for inputting a function setting signal of the user.

한편, 상기와 같은 종래 슬라이드 업형 이동통신단말기의 동작을 살펴보면, 단말기 사용자가 통화하기를 원할 경우 먼저, 상기 단말기(76)의 슬라이딩 커버부 (71)를 상부방향으로 밀게되는데, 이때, 상기 슬라이딩 커버부(71)는 커버부(71)의 후면과 결합되어 있는 몸체부(73)의 레일(72)을 따라 상부방향으로 이동하게 된다. 그리고, 상기 슬라이딩 커버부(71)나 몸체부(73)에 형성된 키패드(75)를 통해 통화하고자 하는 통화 상대방의 전화번호를 눌러 기지국 시스템(77)으로 채널할당을 요구하게된다. 그러면, 상기 단말기(76)의 채널할당 요구신호가 안테나(74)를 통해 기지국 시스템(77)으로 송출하게 되는데, 이때, 사용자는 단말기(76)를 자신에 귀에 대고 기지국 시스템(77)으로부터 송출되는 통화 연결음을 확인하게 된다. 그리고, 상기 기지국 시스템(77)으로부터 채널이 할당되어 통화 상대방과 통화가 이루어지면 자신의 귀에 대고 있는 단말기(76)를 통해 통화를 실행하게 된다. 여기서, 상기 단말기(76)의 송수신상태를 좀 더 양호하게 유지하기위해서는 상기 몸체부(73)의 일측에 구비된 안테나(74)를 상부방향으로 뽑아 사용하면 된다.On the other hand, looking at the operation of the conventional slide-up type mobile communication terminal as described above, if the terminal user wants to make a call, first, the sliding cover portion 71 of the terminal 76 is pushed upwards, wherein the sliding cover The portion 71 moves upward along the rail 72 of the body portion 73 coupled to the rear surface of the cover portion 71. Then, by pressing the phone number of the call counterpart through the keypad 75 formed on the sliding cover portion 71 or the body portion 73 to request a channel assignment to the base station system 77. Then, the channel allocation request signal of the terminal 76 is transmitted to the base station system 77 through the antenna 74, in which the user sends the terminal 76 to his ear and is transmitted from the base station system 77. You will see the ring back tone. When a channel is allocated from the base station system 77 and a call is made to the call counterpart, the call is executed through the terminal 76 placed on its ear. Here, in order to better maintain the transmission and reception state of the terminal 76, the antenna 74 provided on one side of the body portion 73 may be pulled out and used.

그러나, 상기와 같은 종래 슬라이드 업형 이동통신단말기는 안테나를 수동으로 뽑아 올리거나 넣는 방식이기 때문에 단말기 사용자가 통화품질을 양호하게 유지하기위해서는 통화할 때마다 매번 이 안테나를 뽑아 올려주어야 하므로 안테나의 사용이 상당히 불편하였으며, 또한, 단말기 사용자가 안테나를 뽑아 사용하는 것이 불편하여 대부분 안테나를 뽑지않은 상태에서 통화를 실행하게 되므로 그에 따라 단말기의 통화품질도 상당히 저하된다는 문제점이 있었다.However, the conventional slide-up mobile communication terminal as described above is a method of manually pulling up or inserting the antenna, so that the user of the terminal must pull up the antenna every time in order to maintain good call quality. It was quite inconvenient, and also, the user of the terminal is uncomfortable to use the antenna unplugged to perform the call in most unplugged antenna, so there was a problem that the call quality of the terminal is significantly reduced.

이에 본 발명은 상기와 같은 종래 제반 문제점을 해결하기 위해 발명된 것으로, 단말기의 슬라이딩 커버부의 후면 일측에 래크기어부와 이에 연동하는 피니언 기어부를 설치하고 단말기 몸체부의 일측에 회동가능한 몸체축을 상기 피니어의 축과 연동되게 형성하면서 몸체축에 이동가능한 안테나의 일단부를 연결시키므로써,슬라이딩 커버부가 오픈될 경우 안테나도 이동되어 몸체부와 수직된 방향으로 돌출되는 이동식 안테나구조를 갖는 이동통신단말기를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, the pinion gear portion interlocking with the rack gear portion on the rear side of the sliding cover portion of the terminal and the body shaft rotatable on one side of the terminal body portion By connecting one end of the movable antenna to the body shaft while forming in conjunction with the axis of the, to provide a mobile communication terminal having a mobile antenna structure that the antenna is moved and protrudes in a direction perpendicular to the body when the sliding cover is opened. The purpose is.

또한, 본 발명의 다른 목적은 단말기의 부착된 안테나가 최상의 방사상태가 되도록 이동하였다가 복원되므로 그에 따라 단말기의 통화품질을 상당히 향상시키는 이동식 안테나구조를 갖는 이동통신단말기를 제공하는데 있다.     In addition, another object of the present invention is to provide a mobile communication terminal having a mobile antenna structure to significantly improve the call quality of the terminal, since the attached antenna of the terminal is moved and restored to the best radiation state.

상기와 같은 목적을 달성하기 위한 본 발명은 슬라이딩 커버부가 몸체부의 상면을 슬라이딩하는 슬라이드 업형 이동통신단말기에서, The present invention for achieving the above object in the slide-up type mobile communication terminal sliding the upper cover of the body portion,

상기 슬라이딩 커버부의 후면 일측에 래크기어부와 이에 연동하는 피니언기어부가 설치되어 있고, 상기 몸체부의 일측에는 회동가능한 몸체축을 상기 피니언기어의 축과 연동되게 설치하며, 상기 몸체축에는 수평상태에서 수직상태로 선회하면서 이동가능한 안테나의 일단부가 연결되도록 설치되는 이동식 안테나구조를 갖는 이동통신단말기를 제공한다.On the rear side of the sliding cover part, a rack gear part and a pinion gear part interlocked therewith are installed, and on one side of the body part, a rotatable body axis is installed to be interlocked with the axis of the pinion gear, and the body axis is in a vertical state in a horizontal state.

On the other hand, when the call of the terminal 10 is terminated, the user of the terminal 10 pulls the sliding cover 2 downward. Then, the sliding cover portion 2 is moved downward along the rail 3 of the body portion 4 coupled to the rear surface of the cover portion 2.

여기서, 상기 슬라이딩 커버부(2)가 하부방향으로 이동하게 될 경우 이 슬라이딩 커버부(2)의 후면에 설치된 피니언기어(6)가 래크기어(5)를 따라 상부방향으로 회전을 하게 되는데, 이때, 상기 피니언기어(6)가 회전함에 따라 이 피니언기어(6)의 축에 연결된 몸체축(7)도 함께 연동된다. 그리고, 상기 몸체축(7)이 회전을 하게 되면 이 몸체축(7)에 연결된 안테나(8)도 도 3에 도시된 바와같이 몸체부(4)와 수평상태에 있다가 수직상태로 선회하게 된다. 그리고, 상기 슬라이딩 커버부(2)가 몸체부(4)의 레일(3)을 따라 완전히 당겨져 원래위치로 돌아올 경우 상기 슬라이딩 커버부(2)의 후면측에 위치한 피니언기어(6)도 래크기어(5)의 상부측으로 완전히 회전한 상태에 이르게 된다. 이때, 상기 피니언기어(6)가 완전히 회전한 상태가가 되면 이 피니언기어(6)와 연동되는 몸체축(7)에 연결된 안테나(8) 역시 몸체부(4)의 상면으로 복귀하게 된다.Here, when the sliding cover 2 is moved in the lower direction, the pinion gear 6 installed on the rear of the sliding cover 2 is rotated upward along the rack gear 5, At this time, as the pinion gear 6 rotates, the body shaft 7 connected to the shaft of the pinion gear 6 is also interlocked. When the body shaft 7 rotates, the antenna 8 connected to the body shaft 7 also rotates in a vertical state while being in a horizontal state with the body portion 4 as shown in FIG. 3. . In addition, when the sliding cover 2 is completely pulled along the rail 3 of the body 4 and returned to its original position, the pinion gear 6 located on the rear side of the sliding cover 2 is also a rack gear. It reaches the state which rotated completely to the upper side of (5). At this time, when the pinion gear 6 is completely rotated, the antenna 8 connected to the body shaft 7 interlocked with the pinion gear 6 also returns to the upper surface of the body portion 4.

이상 설명에서와 같이 본 발명은 단말기의 슬라이딩 커버부의 후면 일측에 래크기어부와 이에 연동하는 피니언기어부를 설치하고 단말기 몸체부의 일측에 회동가능한 몸체축을 상기 피니어의 축과 연동되게 형성하면서 몸체축에 이동가능한 안테나의 일단부를 연결시킴으로써, 슬라이딩 커버부가 오픈될 경우 래크와 피니언기어의 운동에 따라 안테나도 이동되어 몸체부와 수직된 방향으로 돌출되게 되므로 그에 따라 안테나의 송수신감도를 상당히 높이는 장점을 가지고 있다.As described above, the present invention provides a rack gear part and a pinion gear part interlocked with one side of the sliding cover part of the terminal, and a rotatable body shaft formed on one side of the terminal body part so as to be interlocked with the shaft of the pinion. By connecting one end of the movable antenna, when the sliding cover is opened, the antenna is moved according to the motion of the rack and the pinion gear and protrudes in a direction perpendicular to the body part, thereby increasing the transmission and reception sensitivity of the antenna accordingly. .

또한, 본 발명에 의하면, 단말기의 부착된 안테나가 최상의 방사상태가 되도록 이동하였다가 복원되므로 그에 따라 단말기의 통화품질을 상당히 향상시키는 효과도 있다.     In addition, according to the present invention, since the attached antenna of the terminal is moved to restore the best radiation state, there is an effect of significantly improving the call quality of the terminal accordingly.
