본 발명에 의한 폴더형 이동통신 단말기의 충격완화 및 개폐장치 및 그의 제어방법은 일정 간격만큼 전면케이스를 밀어 열어줌으로써 개방을 용이하게 하고, 차폐시에도 완충적으로 닫혀질 수 있도록 구현한 것으로, 본 발명의 폴더형 이동통신 단말기는 도3에 도시된 바와 같이, 각종 데이터신호를 입력하는 키패드와 송화부가 구비된 본체(1)와; 이동통신 단말기의 상황을 디스플레이하는 LCD와 스피커장치를 포함하는 수화부가 구비된 폴더(2); 및 폴더(2)를 본체(1)에 대해 회동가능하게 결합시키는 힌지부(3)로 크게 구성된다. Shock mitigation and opening and closing device and control method of the clamshell mobile communication terminal according to the present invention is implemented to facilitate the opening by pushing the front case by a predetermined interval, and to be closed buffered even when shielding. As shown in FIG. 3, a folding mobile communication terminal of the invention includes: a main body 1 having a keypad for inputting various data signals and a talker; A folder (2) provided with a receiving unit including an LCD and a speaker device for displaying the situation of the mobile communication terminal; And a hinge portion 3 which rotatably couples the folder 2 to the main body 1.
상기와 같이 구성된 폴더형 이동통신 단말기에 있어서, 본체(1)의 송화부 하측에는 소정크기의 유출입구(1a)가 형성되고, 상기 힌지부(3)에는 폴더의 개폐동작에 따른 각운동을 감지하는 각운동감지센서(4)가 구비된다.In the foldable mobile communication terminal configured as described above, an outlet opening 1a having a predetermined size is formed at the lower side of the talker of the main body 1, and the angular motion of the hinge part 3 is detected according to the opening and closing operation of the folder. An angular motion sensor 4 is provided.
또한, 도4에 도시된 바와 같이 상기 본체(1)에는 각운동감지센서(4)의 감지유무에 따라 인쇄회로기판으로부터 전원을 인가받아 정, 역회전동작하는 모터(5)와; 상기 모터(5)의 축(5a)에 연결되며 그의 회전력을 전달받는 피니언기어(6)와; 버섯모양의 헤드(7a)와 그로부터 연장되는 막대(7b)로 이루어져 상기 본체(1)의 유출입구(1a)내에 위치되며, 그 막대(7b)의 일면에는 상기 피니언기어(6)와 치합하여 그의 회전운동을 직선운동으로 변환하는 랙기어(미도시)가 형성되어 상기 폴더(2)의 개폐동작시 본체(1)의 유출입구(1a)를 통해 유출입되면서 본체(1)와 폴더(2)의 접촉력에 따른 충격을 완화시키는 댐퍼(7)로 구성된다.In addition, as shown in Figure 4, the main body 1 has a motor (5) for forward and reverse rotation by receiving power from the printed circuit board in accordance with the presence or absence of the angular motion sensor (4); A pinion gear 6 connected to the shaft 5a of the motor 5 and receiving a rotational force thereof; It consists of a mushroom head 7a and a rod 7b extending therefrom and is located in the outlet 1a of the main body 1, and one surface of the rod 7b is engaged with the pinion gear 6 so that A rack gear (not shown) for converting the rotational motion into a linear motion is formed to flow in and out through the inlet and outlet 1a of the main body 1 during the opening and closing operation of the folder 2. It is composed of a damper (7) to mitigate the impact of the contact force.
여기에서, 상기 댐퍼(7)는 완충력이 강한 고무재질로 이루어진다. Here, the damper 7 is made of a rubber material having a strong buffering force.
본 발명의 실시예에서는 상기 댐퍼(7)가 피니언(6) 및 랙의 구조에 의해 전후 직진하면서 본체(1)의 유출입구(1a)를 통하여 유출되는 구조를 제시하고 있지만, 이에 국한하는 것은 아니고, 상기 모터(5)의 축에 편심캠을 장착하여 편심량만큼 댐퍼(7)가 승강되도록 할 수도 있다.In the embodiment of the present invention, the damper 7 is shown to flow through the outlet inlet (1a) of the main body 1 while going straight back and forth by the structure of the pinion 6 and the rack, but is not limited thereto. In addition, the eccentric cam may be mounted on the shaft of the motor 5 so that the damper 7 may be lifted by the eccentric amount.
상기와 같이 구성된 본 발명의 작용상태를 도5a 내지 도5e와 도6의 도면을 참조하여 설명하면 다음과 같다.The working state of the present invention configured as described above will be described with reference to FIGS. 5A to 5E and FIG. 6.
본 발명은 폴더(2)의 개폐상황에 따라 두가지 모드로 나뉘어져 동작한다. 즉, 일반적인 폴더(2)의 개폐일때, 즉 문자메세지 확인, 인터넷, 게임등을 하거나, 통화를 시도하기 위해 사용자가 임의로 폴더(2)를 개방하는 경우와, 콜신호착신모드에 의해 폴더(2)를 개방하는 경우에 한해 동작한다.The present invention operates in two modes according to the opening and closing situation of the folder (2). That is, when the general folder 2 is opened or closed, that is, when the user arbitrarily opens the folder 2 for text message checking, the Internet, a game, or attempts to make a call, the folder 2 is opened by the call signal reception mode. Only works if you open).
먼저, 도5a에 도시된 바와 같이 사용자가 임의로 폴더(2)를 개방하는 경우에, 폴더(2)의 열림상태를 각운동감지센서(4)가 감지하고, 이 신호를 MSM(Mobile Station Modem)에 인가한다(S1, S2).First, when the user arbitrarily opens the folder 2 as shown in FIG. 5A, the angular motion sensor 4 detects the open state of the folder 2, and this signal is detected by the mobile station modem (MSM). (S1, S2).
상기 MSM은 폴더(2)가 개방되고 있음을 인식하여 모터(5)에 전원이 인가되도록 제어신호를 인쇄회로기판에 송출한다(S3).The MSM recognizes that the folder 2 is open and transmits a control signal to the printed circuit board so that power is applied to the motor 5 (S3).
상기와 같은 MSM의 제어동작에 의해 상기 모터(5)가 정회전 구동하면, 도5b에 도시된 바와 같이 상기 모터(5)의 축(5a)에 연결된 피니언기어(6)와 댐퍼(7)에 형성된 랙기어의 조합에 의해 회전운동이 직선운동으로 변환되어 상기 댐퍼(7)를 상향이동시킨다. 이에따라 상기 댐퍼(7)가 본체(1)의 유출입구(1a)를 통해 외부로 돌출되는 것이다(S4). When the motor 5 is driven in the forward rotation by the control operation of the MSM as described above, as shown in FIG. 5B, the pinion gear 6 and the damper 7 connected to the shaft 5a of the motor 5 are rotated. The rotational motion is converted into a linear motion by the combination of the rack gears formed to move the damper 7 upward. Accordingly, the damper 7 is protruded to the outside through the outlet 1a of the main body 1 (S4).
도5c 및 도5d에 도시된 바와 같이 상기 폴더(2)를 완전 개방한 상태에서 사용자가 임의시간동안 이동통신 단말기 사용을 완료한 후, 닫힘동작을 수행할 경우에는 상기 폴더(2)가 본체(1)에서 돌출된 댐퍼(7)에 부딪혀 충격을 완화하게 된다(S5, S6). 그리고, 도5e에 도시된 바와 같이 상기 각운동감지센서(4)가 폴더(2)의 닫힘상태를 감지하여 MSM에 인가하게 되면, 상기 MSM은 소정시간(본 실시예에서는 1 ∼ 2초) 경과후 상기 모터(5)를 역회전시켜 상기 댐퍼(7)를 본체(1) 내부 공간으로 유입시킴으로써 상기 본체(1)와 폴더(2)가 완전하게 닫히게 되는 것이다(S7, S8, S9, S10).As shown in FIGS. 5C and 5D, when the user completes the use of the mobile communication terminal for a predetermined time while the folder 2 is completely opened, the folder 2 is stored in the main body (2). The shock is alleviated by hitting the damper 7 protruding from 1) (S5, S6). As shown in FIG. 5E, when the angular motion sensor 4 detects the closed state of the folder 2 and applies it to the MSM, the MSM passes a predetermined time (1 to 2 seconds in this embodiment). Then, the motor 5 is rotated in reverse to introduce the damper 7 into the space inside the main body 1 so that the main body 1 and the folder 2 are completely closed (S7, S8, S9, and S10). .
이와는 별도로 콜신호가 착신되었을 경우(S11)에는, 이를 상기 MSM이 바로 인식하여 모터(5)가 구동하도록 인쇄회로기판에 제어신호를 송출하게 된다. 이에 따라 상기 모터(5)가 구동하여 댐퍼(7)를 상향이동시키게 되고, 폴더(2)와 본체(1)사이의 간격이 벌어짐으로써 상기 폴더(2)가 개방되기 편리한 위치로 놓이게 된다(도5b 상태로 됨).In addition, when a call signal is received separately (S11), the MSM recognizes it immediately and sends a control signal to the printed circuit board to drive the motor (5). Accordingly, the motor 5 is driven to move the damper 7 upwards, and the gap between the folder 2 and the main body 1 is widened so that the folder 2 is placed in a convenient position for opening (FIG. 5b).
상기 상태에서 사용자가 폴더(2)를 개방하여 통화를 하고, 상기 통화가 완료되면, 도5d와 도5e의 동작을 수행하고, 닫혀지게 되는 것이다. In this state, the user opens the folder 2 to make a call. When the call is completed, the user performs the operations of FIGS. 5D and 5E and is closed.
이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것이 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 통상의 지식을 가진자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and will be apparent to those skilled in the art without departing from the technical spirit of the present invention.
전술한 바와 같이 본 발명에 따르면, 종래기술인 힌지부의 스프링 탄성에 의해 쉽게 열려지지 못하도록 설계되어 있는 구조를 모터의 동작에 의해 댐퍼가 상승하여 폴더와 본체사이가 벌어지도록 함으로써 폴더의 개폐를 용이하게 하며, 또한 상기 폴더를 닫을 때 그의 운동에너지 및 이에 따른 충격이 댐퍼를 통해 흡수됨으로써 각종 키패드와 디스플레이부의 액정손상을 방지하고 기기의 수명을 늘릴 수 있는 효과가 있다.According to the present invention as described above, the damper is raised by the operation of the motor is designed so that it is not easily opened by the spring elasticity of the hinge portion of the prior art to facilitate the opening and closing of the folder by opening between the folder and the main body. In addition, when the folder is closed, the kinetic energy and the impact thereof are absorbed through the damper, thereby preventing the liquid crystal damage of various keypads and the display unit and increasing the life of the device.
