It is about.

일반적으로, 폴더형 휴대단말기는 휴대가 용이하도록 본체부의 상면 일 측에 폴더부가 힌지부에 의하여 접철 가능하게 고정되며, 상기 본체부의 배면에 탈착 가능하게 결합되는 밧데리에 의하여 전원을 공급받아 운용되는 휴대용 통신 기기이다.In general, the folding portable terminal is foldably fixed to the upper side of the main body portion by a hinge portion for easy portability, the portable is operated by being supplied with power by a battery detachably coupled to the back of the main body portion Communication device.

이하, 도 1 내지 도 3은 종래의 폴더형 휴대단말기의 폴더 개폐 감지 장치를 도시한 것으로서, 이에 도시한 바와 같이, 종래의 폴더형 휴대단말기(100)는 본체부(110)와, 폴더부(120), 그리고, 상기 본체부(110)의 상면 일 측에 상기 폴더부(120)가 접철 가능하게 결합하는 힌지부(130)로 구성된다.1 to 3 illustrate a folder open / close detection device of a conventional foldable portable terminal. As shown in the drawing, the conventional foldable portable terminal 100 includes a main body 110 and a folder ( 120, and a hinge portion 130 to which the folder portion 120 is foldably coupled to one side of an upper surface of the main body portion 110.

상기 본체부(110)는 케이스 내부에 전자신호를 송수신 및 기타 무선통신을 위한 전자회로기판인 피시비와, 상기 피시비의 상측에 문자 및 숫자 등의 정보를 입력하기 위한 키패드(111)와, 상기 케이스 후면에 착탈 가능하게 부착되어 휴대단말기의 운용상 필요한 전원을 공급하는 밧데리(112)가 부착된다.The main body 110 includes a PCB, which is an electronic circuit board for transmitting and receiving electronic signals and other wireless communications, a keypad 111 for inputting information such as letters and numbers on the PCB, and the case. Removably attached to the rear side is a battery 112 for supplying power necessary for the operation of the mobile terminal is attached.

상기 폴더부(120)는 상기 본체부(110)의 피시비에서 발생한 전기적 신호를받아 휴대단말기의 운용상태를 보이기 위한 엘시디(121)와, 음성정보를 들을 수 있도록 하는 스피커(122)가 구비된다.The folder unit 120 includes an LCD 121 for receiving an electrical signal generated from the PCB of the main body unit 110 to show an operating state of the portable terminal, and a speaker 122 for listening to voice information.

상기 폴더부(120)의 개폐여부에 따라 상기 엘시디(121)에 전원을 온/오프하도록 폴더부(120)의 개폐 여부를 감지하여 감지된 신호를 제어부로 보내기 위한 개폐 감지부가 구비된다.An opening / closing detection unit is provided to detect whether the folder unit 120 is opened or closed so as to turn on / off the power to the LCD 121 according to whether the folder unit 120 is opened or closed and send a detected signal to the controller.

상기 개폐 감지부는 자력을 갖는 자성체와, 상기 자성체에 자력을 감지하는 자기센서(140)로 구성되며, 상기 자성체는 상기 폴더부(120)의 전면에 내설되고, 상기 자기센서(140)는 상기 폴더부(120)의 전면에 내설된 상기 자성체에 대응하는 본체부(110)의 상면에 내설되도록 한다.The opening and closing detection unit is composed of a magnetic body having a magnetic force, and a magnetic sensor 140 for detecting a magnetic force on the magnetic body, the magnetic body is built in the front of the folder unit 120, the magnetic sensor 140 is the folder It is to be installed on the upper surface of the body portion 110 corresponding to the magnetic material in the front of the portion 120.

또한, 상기 자성체는 폴더부(120)의 내부에 내장된 스피커(122)에 사용되는 자성체가 사용될 수 있으면, 이때 자기센서(140)는 폴더부(120)의 스피커(122)에 대응하는 본체부(110)의 전면에 내장되도록 한다.In addition, if the magnetic material can be used a magnetic material used in the speaker 122 built in the folder portion 120, the magnetic sensor 140 is the body portion corresponding to the speaker 122 of the folder portion 120 To be embedded in the front of the (110).

이와 같은 구성에 의하여, 종래의 폴더형 휴대단말기의 폴더 개폐 감지 장치의 동작은, 도 3에서 도시한 바와 같이, 폴더형 휴대단말기를 사용하기 위하여 본체부(110) 상면에 접철된 폴더부(120)를 개방시키면 상기 폴더부(120) 내부에 내장된 스피커(122)에 사용되는 자성체가 상기 본체부(110)에 내장된 자기센서(140)로부터 멀어지게 되면, 상기 자기센서(140)가 자성체의 자력 범위 내에서 벗어나게 되어 상기 자기센서(140)에서 폴더부(120)의 개폐 여부를 감지한 신호가 제어부로 보내고 폴더부(120)의 엘시디(121)에 전원을 인가하도록 한다.By such a configuration, the operation of the folder open / close detection device of the conventional clamshell portable terminal is, as shown in FIG. 3, the folder portion 120 folded on the upper surface of the main body 110 to use the clamshell portable terminal. If the magnetic body used for the speaker 122 embedded in the folder unit 120 is moved away from the magnetic sensor 140 embedded in the main body unit 110, the magnetic sensor 140 is magnetic. The magnetic force is out of the range of the magnetic sensor 140 to detect whether the folder portion 120 is opened or closed to send to the control unit to apply power to the LCD 121 of the folder portion 120.

또한, 사용자가 폴더형 휴대단말기를 사용한 후 폴더부(120)를 본체부(110)에 접철되도록 힌지부(130)를 중심으로 회전시켜 자성체의 자력 범위 내에 자기센서(140)가 위치하게 되면, 자기센서(140)에 의해 감지된 신호가 제어부에 입력되어 엘시디(121)의 전원을 차단하도록 한다.In addition, when the user uses the foldable portable terminal, the folder unit 120 is rotated about the hinge unit 130 so as to be folded to the main body unit 110 so that the magnetic sensor 140 is positioned within the magnetic force range of the magnetic body. The signal sensed by the magnetic sensor 140 is input to the controller to cut off the power of the LCD 121.

그러나, 상기 자기센서(140)에서 감지하는 상기 자성체의 자력 범위가 제한됨에 따라 본체부(110) 상면으로부터 폴더부(120)가 개방되는 개방각(Θ)을 자유롭게 조절하기가 어렵고, 조절을 한다 하더라고 감도가 높은 자기센서를 사용하거나, 또는 자력의 범위가 넓은 즉, 자력이 강한 자성체를 사용하여야 하여 개방각(Θ)을 조절해야하는 문제점이 발생한다.However, as the magnetic force range of the magnetic body sensed by the magnetic sensor 140 is limited, it is difficult to freely adjust the opening angle Θ at which the folder 120 is opened from the upper surface of the main body 110, and adjust. However, a problem arises in that the opening angle Θ is adjusted by using a magnetic sensor having high sensitivity or by using a magnetic body having a wide range of magnetic force, that is, a strong magnetic force.

또한, 폴더형 휴대단말기(100)의 사용자가 엘시디(121)에 디스플레이 되는 정보를 확인하기 위해서는 폴더부(120)가 본체부(110) 상면으로부터 90°이상 개방되어야 하는데, 상기 자기센서(140)가 자성체의 자력을 감지하는 범위는 30°이내이기 때문에 30 ~ 90°의 범위에서는 엘시디에 불필요한 전원이 인가되어 밧데리의 사용시간을 단축시키는 문제점이 발생한다.In addition, in order for the user of the folding portable terminal 100 to check the information displayed on the LCD 121, the folder unit 120 should be opened at least 90 ° from the upper surface of the main body unit 110. The magnetic sensor 140 Since the magnetic field of the magnetic body detects magnetic force within 30 °, unnecessary power is applied to the LCD in the range of 30 to 90 °, thereby shortening the battery usage time.

상기 문제점을 해결하기 위하여 안출된 본 발명에 따르면 보다 적절한 폴더부의 개방각 이후에서 엘시디에 전원이 인가되도록 하기 위한 폴더형 휴대단말기의 폴더 개폐 감지 장치의 제공을 그 목적으로 한다.According to the present invention devised to solve the above problems, it is an object of the present invention to provide a folder opening and closing detection device of a clamshell portable terminal for applying power to the LCD after the opening angle of a more appropriate folder.

폴더형 휴대단말기(1)의 본체부(10)로부터 폴더부(20)가 개방되는 상태에 따라, 먼저, 폴더부(20)가 본체부(10)의 상면에 접철된 상태 즉, 개방각이 0°인 상태와, 폴더부(20)가 개방되어 상기 폴더형 휴대단말기(1)의 이용자가 폴더부(20)의 전면에 구비된 엘시디를 통하여 디스플레이되는 정보를 확인할 수 있는 개방각 90°인 상태와, 그리고, 폴더부(20)가 본체부(10)로부터 완전 개방된 개방각 150°인상태로 나눌 수 있다.According to the state in which the folder portion 20 is opened from the main body portion 10 of the clamshell portable terminal 1, first, the state in which the folder portion 20 is folded on the upper surface of the main body portion 10, that is, the opening angle is changed. 0 ° state, the folder portion 20 is opened so that the user of the foldable portable terminal 1 has an opening angle of 90 ° so as to confirm the information displayed through the LCD provided on the front of the folder portion 20. And the folder portion 20 can be divided into a state with an opening angle of 150 ° completely opened from the main body portion 10.

따라서, 폴더부(20)의 하부 내측면에 구비된 자기센서(41)가 폴더 고정돌기(31)의 외주면의 개방각 90°이전 즉, 자성체(42)가 구비되지 않은 구간에서는 자기 감지 신호를 발생시키기 않음으로써 제어부에서 폴더부(20)의 엘시디로 전원을 인가하지 않도록 한다.Therefore, the magnetic sensor 41 provided on the lower inner surface of the folder portion 20 is before the opening angle of 90 ° of the outer peripheral surface of the folder fixing projection 31, that is, in the section where the magnetic body 42 is not provided, the magnetic sensing signal is provided. By not generating, the control unit does not apply power to the LCD of the folder unit 20.

그리나, 폴더부(20)가 힌지부(30)를 회전하여 본체부(10)로부터 개방되면, 상기 자기센서(41)는 폴더부(20)의 개방각 90°이후로 폴더 고정돌기(31) 내부에 내설된 자성체(42)와 접하여 자력 감지 신호를 제어부에 보내어 제어부가 폴더부(20)의 엘시디(미도시)로 전원을 인가하도록 한다.However, when the folder portion 20 rotates the hinge portion 30 and is opened from the main body portion 10, the magnetic sensor 41 has a folder fixing protrusion 31 after the opening angle of the folder portion 90 °. The magnetic force 42 is contacted with the internally installed magnetic body 42 to transmit a magnetic force detection signal to the controller so that the controller applies power to an LCD (not shown) of the folder unit 20.

또한, 상기된 폴더부(20)의 엘시디에 전원이 온/오프되는 개방각은 항상 90°고정되는 것은 아니며, 폴더형 휴대단말기(1)의 폴더부(20)가 개방되는 형태나 또는 사용상태에 따라, 폴더 고정돌기(31) 내부의 자성체(42)가 가설되는 개방각의 범위에 따라 조절 가능하다.In addition, the opening angle at which the power is turned on / off in the LCD of the folder part 20 is not always fixed by 90 °, and the folder part 20 of the clamshell portable terminal 1 is open or in a state of use. According to this, the magnetic body 42 inside the folder fixing projection 31 is adjustable according to the range of the opening angle is hypothesized.

이상 설명한 바와 같이, 본 발명에 따르면, 사용자가 디스플레이 되는 휴대단말기의 영상 정보를 감지할 수 있는 폴더부의 엘시디로 인가되는 전원을 절약하여 밧데리의 사용 시간을 증가시키고, 폴더부가 적절하게 제대로 닫히지 않은 경우에는 전원을 차단할 수 있는 효과를 갖으며, 또한, 폴더부의 엘시디에 전원을 인가하기 위한 폴더부의 개방각을 미세 조절할 수 있는 효과를 갖는다.As described above, according to the present invention, when the user saves the power applied to the LCD of the folder unit that can sense the image information of the displayed mobile terminal, increases the usage time of the battery, and the folder unit is not properly closed. It has the effect of shutting off the power, and also has the effect of finely adjusting the opening angle of the folder portion for applying power to the LCD of the folder portion.
