The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication terminal having a slide module for semi-automatically sliding the second body with respect to the first body.

The mobile communication terminal is a portable wireless communication device. Such mobile communication terminals may be classified into various classifications, such as bar type, flip type, fold type, slide type, and swivel type, depending on their mechanical form.

Among them, the slide-type mobile communication terminal includes a main body (or first body) in which a printed circuit board is embedded and a battery is mounted, and a slide unit (or second body) in which a display is mounted. Here, the slide portion is slid relative to the main body portion in an open state covering only a part of the main body portion in a closed state disposed to completely cover the main body portion.

For such sliding, a slide module is installed between the main body portion and the slide portion. In particular, recently, when the user pushes the slide part to some extent, the semi-automatic slide module, in which the remaining sliding is automatically made by an elastic force, is widely used.

However, such a slide module is formed in a plate shape and is formed of members that are mounted on facing surfaces of the main body portion and the slice portion, respectively, and merely slide with respect to each other, thereby requiring a space (area) in which such members are installed. Accordingly, the sliding stroke of the slide part is bound to have a certain limit due to the influence of such members. This also means that there is a limit in reducing the area where the slide part covers the main body part, that is, the area that cannot be utilized even in the open state.

Furthermore, the exposure of the signal line electrically connecting the main body portion and the slide portion during operation of the slide module is aesthetically undesirable. In addition, the signal line exposed separately from the slide module may be damaged by contact with the main body.

In view of the necessity as described above, the present invention is to provide a mobile communication terminal having a slide module that can maximize the sliding stroke.

In order to achieve the above object, the slide module according to an aspect of the present invention includes a connection guide portion, a rotary lever, a sliding slot, and a signal line storage portion.

The connection guide part is formed of a guide rail and a rail receiving part corresponding to each other, and slidably connects the first body and the second body. At this time, the direction of the connection guide portion is disposed to face the longitudinal direction of the first body or the second body, the sliding of the second body is made along the longitudinal direction of the first body. The rotary lever is rotatably mounted to either one of the first body and the second body. As the first body or the second body is slid, the other end of the rotary lever rotates while drawing an arc-shaped trajectory with a predetermined radius. The other end of the rotary lever is inserted into a sliding slot formed along the width direction of the other of the first body or the second body. Accordingly, the other end of the rotary lever slides along the sliding slot, thereby converting a rotational movement about one end of the rotary lever into sliding with respect to the longitudinal direction of the first body of the second body. At this time, the elastic force providing portion is formed between the rotary lever and the body that is rotatably mounted, to give an elastic force to the rotation of the rotary lever. Accordingly, the second body is provided with an elastic force during sliding with respect to the first body, thereby sliding automatically.

Accordingly, the sliding guide is guided by the connecting guide portion, semi-automatic sliding is possible by the rotary lever, the sliding slot and the elastic force providing portion. At this time, as a rotation lever or the like is introduced for the semi-automatic sliding, the stroke of the semi-automatic sliding can be made longer.

The rotary lever may be composed of a rotating shaft, a sliding shaft, and a connecting rod. The axis of rotation is rotatably coupled to the body on which it is installed. For such rotatable coupling, the housing may further include a housing coupled to the body on which the rotating shaft is installed. The housing has a hollow shape in which both ends are opened to rotatably receive the rotation shaft therein. The sliding shaft is formed to be inserted into the sliding slot. The connecting rod is formed to connect the rotating shaft and the sliding shaft to determine the radius of the semi-circular rotating trajectory formed by the sliding shaft.

 The signal line accommodating part is formed on the rotation lever to accommodate the signal lines for electrically connecting the first and second bodies. The signal line storage part may have a hollow part respectively formed in the rotating shaft and the sliding shaft, and a receiving groove formed in the connecting rod and communicating with the hollow parts. By employing the signal line storing portion, it is possible to prevent the signal line from being exposed to the outside during the operation of the slide module.

The elastic force providing unit may include a fixed cam, a movable cam and an elastic member. The fixed cam and the movable cam are mounted on the housing and the rotating shaft, respectively. Here, the fixed cam is fixedly coupled to the housing, but the movable cam is slidably coupled with respect to the axial direction of the rotating shaft. For this coupling, the fixed cam and the movable cam may be configured in a hollow form surrounding the outer circumference of the rotating shaft. In addition, the fixed cam and the movable cam respectively have corresponding hills and valleys to impart rotational force to the rotary lever by their interaction. At this time, an elastic member is formed between the movable cam and the rotary shaft, thereby enabling elastic rotation of the rotary lever by its elastic force.

The sliding guide part is formed between the rotating shaft and the movable cam to guide the axial sliding with respect to the rotating shaft of the movable cam. The sliding guide part may include a slide groove formed in the axial direction on any one of the rotating shaft and the movable cam, and a slide protrusion formed on the other of them and inserted into the slide groove to slide.

A mobile communication terminal having a slide module according to another aspect of the present invention includes a first body, a second body, and the above slide module.

As described above, as the stroke of the slide module can be enlarged, the exposure space of the first body is maximized in the open state in which the second body slides with respect to the first body to expose the first body. Accordingly, it is possible to utilize even a space that has not been utilized conventionally. In particular, QWERTY KEY can be arranged in such exposed space. This is not to enlarge the first body itself, but to utilize its unused space, and it is useful not to be opposed to the slimming tendency of the terminal in that the size of the first body does not increase according to this utilization.

Furthermore, as the signal line storing part is formed, the signal line is not exposed to the outside during the sliding of the second body with respect to the first body. This ensures that the aesthetics are not impaired according to the exposure of the signal line during sliding opening and closing of the terminal, and the signal line is prevented from being damaged, thereby ensuring smooth operation of the terminal.

The elastic force providing unit 370 will be described with reference to FIGS. 3 and 4.

3 is a partial cross-sectional view taken along the line III-III of FIG. 2, and FIG. 4 is an enlarged exploded perspective view of the fixed cam and the movable cam of FIG.

The fixed cam 371 is mounted to a wall that defines the inner hollow of the housing 360. The movable cam 373 is slidably mounted to the rotary shaft 331 along its axial direction, and does not rotate independently with respect to the rotary shaft 331. The elastic member 375 is disposed between the housing 360 and the movable cam 373 to press the movable cam 373 against the fixed cam 371. The housing 360 is coupled to the second body 200 by fastening means 380 such as, for example, a bolt.

Referring to FIG. 4, the fixed cam 371 and the movable cam 373 have a hollow shape surrounding the rotating shaft 331. Further, on the facing surfaces of these 371 and 373, protruding portions 371a and 373a and valleys 371b and 373b which are not formed are formed, respectively. Further, a guide protrusion 373c is formed on an inner wall defining the hollow portion of the movable cam 373, and is inserted into the slide groove 331b formed in the axial direction on the outer circumferential surface of the rotation shaft 331. The guide protrusion 373c forms a sliding guide part together with the slide groove 331b, so that the movable cam 373 can slide along the axial direction of the rotation shaft 331.

Referring back to FIG. 3, the signal line SL for electrically connecting the first body 100 and the second body 200 to the second body 200 through the hollow part 331a of the rotation shaft 331. Extend into. A detailed connection state of the signal line SL will be described in more detail with reference to FIG. 5 (and FIG. 2).

FIG. 5 is an enlarged perspective view of a rotating lever for explaining a structure in which a signal line is accommodated in the rotating lever of FIG. 2.

As illustrated in the figure, the signal line storage part is formed in the rotary lever 330 to receive a signal line SL electrically connecting the first body 100 and the second body 200. Specifically, the signal line storing part includes a hollow part 331a of the rotating shaft 331 and a receiving groove 335a formed in a groove shape on the connection rod 335 and a hollow part 333a of the sliding shaft 333. Accordingly, the signal line SL electrically connected to the printed circuit board (not shown) embedded in the first body 100 extends to the outside through the sliding slot 350 of the first body 100. The signal line SL passes through the hollow portion 333a of the sliding shaft 333 of the rotary lever 330-the receiving groove 335a of the connecting rod 335-the hollow portion 331a of the rotating shaft 331. It is electrically connected to a display module (not shown) in the second body 200.

Next, the operation method of the slide module and a mobile terminal having the same according to the present invention will be described.

Referring to FIG. 1, the user grips the first body 100 to push the second body 200 into an open state. In this case, the connecting guide 310 guides the sliding direction of the second body 200 with respect to the first body 100 (see FIG. 2).

Referring to FIG. 2, in the process of pushing the second body 200, the rotation shaft 331 of the rotation lever 330 is semi-automatically rotated by the elastic force providing unit 370 (see FIG. 3). When the rotary lever 330 rotates, the sliding shaft 333 of the rotary lever 330 is caught by the sliding slot 350 of the first body 100 and only slides along it. Accordingly, the second body 200 is semi-automatically sliding with respect to the first body 100 as the connection guide 310 guides.

3 and 4, the operation of the elastic force providing unit 370 is as follows.

As the second body 200 is pushed, the rotating lever 330 inserted into the sliding slot 350 is caught and rotated about the rotating shaft 331. Accordingly, the movable cam 373 slidably coupled to the rotation shaft 331 may elastically interact with the fixed cam 371 coupled to the housing 360.

Specifically, the peak 371a of the movable cam 373 rides over the peak 371a from the valley 371b of the fixed cam 371 while being pressed by the elastic member 375 against the fixed cam 371. Proceed in the direction. In this process, the movable cam 373 slides in the axial direction of the rotation shaft 331 in a direction away from the fixed cam 371 under the guides of the slide guides 331b and 373c while winning the elastic force of the elastic member 375. Accordingly, when the peak portion 373a of the movable cam 373 faces the peak portion 371a of the fixed cam 371, the distance between the movable cam 373 and the fixed cam 371 is maximized and the elastic member 375 is spaced apart. The compression force of is also maximized. In this state, the peak portion 373a of the movable cam 373 is rotated semi-automatically by the elastic pressing force of the elastic member 375 while riding over the peak portion 371a of the fixed cam 371. This semi-automatic rotation ends at the moment when the elastic member 375 is fully inflated, that is, at the point where the peak portion 373a of the movable cam 373 rests on the valley portion 371b of the fixed cam 371.

Here, the semi-automatic rotation within a predetermined angle range in the elastic force providing unit 370 has a large rotational displacement by the connecting rod 335 of the rotary lever 330 having a predetermined length, this rotational displacement is the sliding shaft 333 ) And the second slot 200 semi-automatically sliding with respect to the first body 100 by the mutual cooperation of the sliding slot (350). Accordingly, while sliding between the open and closed states of the terminal is implemented semi-automatically, it is possible to maximize the sliding stroke.

Referring to FIG. 5, the signal line SL connecting the first body 100 and the second body 200 is rotated during the rotation of the rotary lever 330 for semi-automatic sliding of the second body 200 as described above. The signal line storing parts 331a and 333a and 335a formed in the lever 330 are accommodated so as not to be exposed to the outside. Accordingly, there is no possibility of appearance problems or damage caused by the signal line SL being exposed to the outside.
