Field of the Invention The present invention relates to a portable terminal, and in particular, a configuration for opening and closing of a sliding cover is very simple, the opening and closing operation is sure, and is suitable for suppressing the deterioration of the opening and closing performance of the sliding cover due to component wear in the long term. A slide hinge module and a portable terminal using the same.

In general, a communication terminal may be classified into a wired or wireless communication terminal, and a wired communication terminal is a typical office or home telephone, and a wireless communication terminal is a typical example of a PCS, a cellular phone, or a PDA. Wireless communication terminals are commonly referred to as mobile communication terminals or portable terminals because they provide portability and mobility to a user.

Due to the development of the technology, such a portable terminal provides a user with text information, image information, a game, etc., beyond the step of delivering only simple voice information. The type of the mobile terminal is largely a bar type and a flip type with a cover. It can be divided into flip type and folder type.

Folder-type mobile terminal has a structure that can open and close the folder when a call or mobile phone can solve the problem that the length of the bar-type or flip-type mobile terminal, but the hinge portion connecting the upper folder and the lower folder is easily damaged. There is a problem.

In order to solve the problem of the folding portable terminal, a sliding portable terminal in which the cover is moved up and down automatically by a sliding type has been proposed. Until now, most sliding type mobile terminals are opened and closed by sliding the cover semi-automatically using the elastic force of the torsion spring. However, when the elastic force of the torsion spring is used as described above, the elastic force of the torsion spring decreases as time passes, and the problem of opening and closing of the cover is deteriorated. Therefore, in recent years, various types of slide-type portable terminals have been developed to avoid the use of torsion springs.

2 is a reference perspective view showing a portable terminal using a slide hinge module of the present invention according to the first embodiment.

As shown, the portable terminal of the present invention includes a main body 100, a sliding cover 200, a rotating arm 300 constituting the hinge module (H) and the driving means 400. As a result, when the user applies a force to the sliding cover 200, the sliding cover 200 is manually moved from the main body 100 to a predetermined position, and when the user passes the predetermined position by the elastic restoring force of the slide hinge device H. The sliding cover 200 is opened and closed while automatically sliding.

The main body 100 is provided with a keypad 110 in the lower front, the upper portion of the main body 100, the rotating arm 300 is accommodated in the substantially fan-shaped concave portion 120 is formed so that the rotation operation is formed. do.

The sliding cover 200 is installed to open and close while sliding in the vertical direction on the front of the main body 100. However, when the sliding cover 200 is moved upward and the keypad 110 of the main body 100 is exposed to the outside, the sliding cover 200 is opened. In contrast, the sliding cover 200 is moved downward. When the keypad 110 of the exposed body 100 is hidden, the sliding cover 200 is considered to be closed. In order to smoothly open and close the sliding cover 200, a predetermined slide protrusion for receiving the guide rails 230 and the guide rails 230 formed in the main body 100 and the sliding cover 200. Preferably, 130 is formed.

The rotary arm 300 and the drive means 400 serves to open and close the sliding cover 200 by cooperating together while forming a slide hinge module (H). In the following, the configuration thereof will be described in detail.

3 is a perspective view of a hinge module according to the first embodiment of the present invention, Figure 4 is an exploded perspective view for explaining the hinge module of the present invention according to the first embodiment, Figure 5 is a first embodiment Figure 9 is a plan view for explaining the hinge module of the present invention.

As shown, the hinge module of the present invention is composed of a rotary arm 300 and the drive means (400).

The rotary arm 300 receives the linear force provided by the elastic restoring force of the compression spring 420 and rebounds to open and close the sliding cover 200 while rotating upward or downward. To this end, the rotary arm 300 has a contact portion 310 for converting a linear force into a rotary force at the rear end.

The contact portion 310 is rotatably connected to the connecting portion 440 of the driving means 400 by the shaft 314, the end of the shaft 314 penetrating the connecting portion 440 to the earring for separation 315) is fitted. In this case, a predetermined through hole 441 through which the shaft 314 penetrates is formed in the connection part 440. In addition, the profile of the contact portion 310 is formed of the first inclined line 312 in the opening direction and the second inclination line 313 in the closing direction inclined on both sides of the protruding transition portion 311. This can be seen as a general ">" form. Here, the transition portion 311 of the contact portion 310 is formed to be curvature, not sharply formed so as to suppress the wear caused by the contact. In addition, the first slope line 312 and the second slope line 313 are formed in a symmetrical form, that is, isometric and equilateral. Then, when the sliding cover 200 is opened and closed, the moving distances reaching the transition time point are the same. In addition, if the first inclination line 312 and the second inclination line 313 are configured asymmetrically by applying a slight deformation to the contact portion 310, the transition point is reached when the sliding cover 200 is opened and closed. The moving distances can be different from each other (this will be described later with reference to FIG. 7).

In addition, the rotary arm 300 is rotatably coupled with the sliding cover 200. To this end, a cylindrical joint protrusion 316 is simply formed or installed at the tip of the rotary arm 300, and a joint groove 216 into which the joint protrusion 316 is fitted is formed in the sliding cover 200 (Fig. 2). Here, the joint groove 216 is formed in the form of a long hole in the left and right directions to allow the left and right displacement or play of the joint protrusion 316 according to the movement trajectory of the end of the rotary arm 300 when rotating.

The driving means 400 includes a pusher 410, a compression spring 420 and the housing 430. First, the pusher 410 is installed in the housing 430 to enable a straight reciprocating movement, and a flat slip surface 411 is formed in contact with the profile of the contact portion 310 of the rotary arm 300.

The compression spring 420 is received deep within the housing 430 and serves to push the pusher 410 in the direction in which the contact portion 310 is installed by the elastic restoring force.

The housing 430 is formed to have a predetermined accommodation space for receiving the pusher 410 and the compression spring 420. The housing 430 is open at one side to facilitate the reception of the pusher 410 and the compression spring 420. In addition, a predetermined opening portion 431 is formed at the front end of the housing 430 so that the front end of the pusher 410 having the slip surface 411 is exposed to the outside. In addition, a connection part 440 is formed at the front end of the housing 430 so that the contact part 310 of the rotary arm 300 is rotatably connected. Here, the contact portion 310 is coupled to an appropriate position of the connection portion 440 so that the profile can remain in contact with the slip surface 411 of the pusher 410.

6a to 6c are reference views for explaining the operation of the hinge module when opening and closing the sliding cover according to the first embodiment of the present invention.

As shown, Figure 6a shows the state of the slide hinge module in a state in which the sliding cover 200 is completely closed, the first inclined line 312 and the pusher formed in the closing direction of the contact portion (310) The slip surface 411 of 410 is in balance with the forces in contact with each other. At this time, the joint protrusion 316 is in a state located inward of the joint groove 216.

When the sliding cover 200 is moved by the upward direction opened by the user while the sliding cover 200 is closed as described above, when the sliding cover 200 starts to move, the rotary arm 300 connected to the sliding cover 200 is rotated. . At this time, the pusher 410 is gradually pushed while the contact portion 310 of the rotary arm 300 also rotates. Then, the elastic restoring force of the compression spring 420 resists the rotation of the contact portion 310 while resisting the pusher 410 retreating toward itself. As a result, the sliding cover 200 has a tendency not to open against the force of the user.

At this time, when the user removes the force applied to the sliding cover 200, the sliding cover 200 is retracted by the elastic restoring force of the compression spring 420 to return to the original state as shown in Figure 11a. However, if the user continues to apply the force while overcoming the resistance of the compression spring 420, the first inclination line 312 of the contact portion 310, and then the transition portion 311 pushes the pusher 410 The state of FIG. 6B is reached. At this time, the joint protrusion 316 is in a state located outside the joint groove 216.

6B illustrates the state of the slide hinge module at the moment when the transition portion 311 of the contact portion 310 and the slip surface 411 of the pusher 410 face each other. At this point, the elastic restoring force of the compression spring 420 becomes a transition point in which the sliding restoring force acts in the opening direction in the closing direction of the sliding cover 200. In this state, when the compression spring 420 is pressed and compressed, the elastic energy is accumulated at the highest level, and when the contact part 310 rotates a little more and passes the transition point, the contact part 310 has the sliding cover 200. It turns sharply in the open direction. Therefore, afterwards, even if a user does not apply force to the sliding cover 200, the sliding cover 200 automatically slides upwards to be in a completely open state as shown in FIG. 6C.

FIG. 6C illustrates a state of the slide hinge module in which the sliding cover 100 is completely opened. The second slope line 313 and the second inclination line of the contact portion 310 formed in the closing direction of the sliding cover 200 are illustrated in FIG. The slip surface 411 of the pusher 410 is in contact. At this time, since the elastic energy accumulated in the compression spring 420 is at a minimum state, and the contact portion 310 and the pusher 410 have stable surface contact, the sliding cover 200 is opened unless external force is applied again from the outside. State is maintained.

only. In the opening and closing process of the sliding cover 200 as described above, the left and right displacement is generated while the rotary arm 300 draws a curved trajectory. Accordingly, the joint protrusion 316 of the distal end of the rotary arm 300 moves left and right within the joint groove 216 of the sliding cover 200.

As such, the rotating arm 300 converts the linear force provided by the driving means 400 into the rotational force by the contact portion 310 formed at the rear end thereof to rotate the sliding cover 200. It will open and close. In this process, although the contact friction between the profile of the contact portion 310 and the pusher 410 always occurs, unlike the rotation cam according to the prior art, the wear and tear caused by the strong shear resistance hardly occurs and the opening and closing of the sliding cover 200 The operation is made clearer.

Meanwhile, in order to be in a closed state in the open state of the sliding cover 200, a user force may be applied in a downward direction of closing the sliding cover 200 in the state of FIG. 6C. At this time, the user applies a force only until the transition time point at which the transition part 311 of the contact part 310 and the slip surface 411 of the pusher 410 face each other, and the sliding cover 200 is automatically closed. This operation is substantially the same as when the sliding cover 200 is opened, so a detailed description thereof will be omitted.

Next, the configuration of the present invention according to the modified embodiment will be described.

7 is a reference diagram for explaining a rotating arm of the present invention according to the first modified embodiment.

As shown, the modified rotation arm according to the present invention has an open direction in which the profile of the contact portion 320 in contact with the slip surface 411 of the pusher 410 is inclined on both sides of the protruding transition portion 321. The first inclined line 322 and the second inclined line 323 of the closing direction is formed, the first inclined line 322 and the second inclined line 323 may be formed asymmetrically.

As described above, the distances at which the sliding cover 200 reaches the transition point when the sliding cover 200 is opened and closed by the asymmetric structures of the first and second inclined lines 322 and 323 may be different. have. For example, as shown in FIG. 7, when the contact part 320 is formed in the opening direction, the distance reaching the transition point when the sliding cover 200 is opened is shorter than the distance reaching the transition point when the sliding cover 200 is closed. Therefore, the sliding cover 200 can be opened more easily. On the contrary, when the contact part 310 is formed in the closing direction, the distance reaching the transition point becomes short when the sliding cover 200 is closed, so that the sliding cover 200 can be easily closed. Therefore, if the asymmetric structure of the contact portion 310 is properly utilized, the transition point of the sliding cover 200 can be adjusted to the user's convenience.

8 is a reference diagram for explaining a rotating arm of the present invention according to a first embodiment modified in another form.

As shown, the rotary arm according to the present invention has a profile of the contact portion 330 in the neutral direction of the rest portion 333, the first inclined line 334 in the open direction inclined to both sides around the rest portion 333 And a second slope line 335 in the closing direction.

Thus, the slip surface 411 of the pusher 410 is in contact with the rest portion 333 in the middle of the alternating contact between the first inclined line 334 and the second inclined line 335 to balance the force. Thus, the sliding cover 200 has a rest period which maintains only half the open state. On the other hand, before and after the pause, the contact portion 330 reacts with the pushing force of the pusher 410 and rotates in another direction in which the sliding cover 200 is opened and closed. Here, the transition parts 331 and 332 formed while the resting part 333 and the first inclined line 334 and the second inclined line 335 meet each other between the opening direction and the neutral direction of the sliding cover 200, And a transition between the closing and neutral directions. As described above, when the sliding cover 200 has a deformed configuration that allows the opening and closing of the sliding cover 200 step by step, the degree of exposure of the portable terminal main body 100 can be set in steps.

Here, the profile of the contact portion 330 may be modified to have a larger number of inclined lines as needed.

On the other hand, the present invention may take the configuration that the pusher 410 of the drive means 400 as well as the rotary arm 300 is deformed. This will be described below with reference to FIGS. 9 to 14.

9 to 14 are partial reference views for explaining the pusher of the driving means according to the present invention according to the first embodiment which is modified in various forms.

First, FIG. 9 is a symmetrical view of a first acceleration line 452 and a second acceleration line 453 inclined at both sides of the shifting portion 451 protruding from the profile of the pusher 450 according to the present invention. It is characterized in that formed in the <"form. According to such a configuration, the moment when the transition portion 311 of the contact portion 310 comes into contact with the shift portion 451 of the pusher 450 and goes to the first acceleration line 452 or the second acceleration line 453. As the operation is made rapidly, the transition operation of changing the opening and closing direction of the sliding cover 200 is made rapidly, and the opening and closing speed of the sliding cover 200 is also increased.

Here, when the first acceleration line 452 and the second acceleration line 453 of the pusher 450 are formed to be symmetrical with each other, the speed at which the sliding cover 200 opens and closes and the distance to the transition point are equal. .

Meanwhile, when the first acceleration line 452 'and the second acceleration line 453' are formed to be asymmetric with respect to the shift portion 451 'of the pusher 450', the sliding cover is formed as shown in FIG. The speed at which the 200 opens and closes and the distance to the transition point when opening and closing vary. Therefore, if the asymmetric structure of the pusher 450 ′ is properly used, the transition point of the sliding cover 200 can be adjusted to the user's convenience.

11 is characterized in that the profile of the pusher 460 has a neutral portion 461 with acceleration lines 462 and 463. To this end, the profile of the pusher 460 is protruded so that the neutral portion 461 formed in a plane without inclination and the first acceleration line 462 and the second acceleration line 463 inclined at both sides with respect to the neutral portion 461. Is formed. According to such a configuration, when the contact portion 310 is in contact with the neutral portion 461 of the pusher 460, the opening and closing speed of the sliding cover 200 is made smooth as before the deformation, and then the first acceleration line 462. Alternatively, it has an operating characteristic that is made suddenly while being crossed over to the second acceleration line 463.

12 is characterized in that the profile of the pusher 470 is formed flat, but the recessed groove 471 is formed in the center is the transition portion 311 is matched. According to this configuration, at the time when the transition part 311 and the concave groove 471 are mated when the sliding cover 200 is opened and closed, it has both a pause and a transition point at which the opening and closing operation of the sliding cover 200 is temporarily suspended. do.

As such, when the rotary arm 300 'is configured to be elastic in a two-section link structure, its end portion can move while drawing a linear orbit rather than an arc shape. Therefore, the recess 120 'is deformed into a triangular shape in a fan shape. For the same reason, the joint groove 216 ′ of the sliding cover 200 into which the joint protrusion 316 is inserted is formed only to the extent that the joint protrusion 316 is rotatably fitted in the form of a left-right direction.

As such, when the rotary arm 300 'is deformed into a flexible two-section link structure, the left and right widths of the trajectory drawn during rotation can be reduced. Therefore, the configuration space for opening and closing of the sliding cover 200 can be reduced, and a space for installing other components can be secured, thereby facilitating the implementation of a slim portable terminal having a thin left and right width and thickness.

16 is a reference perspective view for explaining the rotating arm of the present invention according to the first embodiment modified in another form.
