The present invention relates to a slide-type portable terminal capable of opening and closing the upper body by sliding up and down with respect to the lower body, and more particularly, the upper-body while maintaining the advantages inherent in the slide-type portable terminal. By separately partitioning the LCD screen, the LCD screen can be erected at an angle, so that the portable LCD device can stand on the LCD screen to more conveniently watch (view) mobile multimedia broadcasting or video through the LCD screen. It is about.

A slide type terminal in a portable terminal such as a mobile phone, a personal digital assistant (PDA), an MP3 player, a portable multimedia player (PMP), a digital multimedia broadcasting mobile phone (DMB phone), and the like is shown in FIG. Likewise, the upper main body 20 is connected to the lower main body 10 by a predetermined sliding mechanism (not shown), and is configured to slide up and down. Such a slide type portable terminal provides a unique design aesthetic different from the so-called 'bar type', 'flip type', or 'folding type', which have been mainstream in the past. It can be said that it can be configured in a very compact form.

In such a slide-type portable terminal, a plurality of input key buttons 12 are installed on the front of the lower main body 10, and uses such as a liquid crystal screen 22 and a 'navigation' on the front of the upper main body 20. The function keys 24 used to have the structure installed. Therefore, while the large liquid crystal screen 22 exposed to the upper main body 10 can be always checked, when the upper main body 20 is pushed up against the lower main body 10, the input key button on the lower main body 10 side is pressed. (12) can also be used.

In such a slide type portable terminal, a so-called 'semi-automatic slide mechanism' is known in which the upper body 20 is automatically opened and closed by the role of a predetermined elastic member when the upper body 20 is moved to a predetermined point. Moreover, what is called an "automatic slide mechanism" which opens and closes automatically by a motor etc. is known.

Among them, conventional examples of slide-type portable terminals using a semi-automatic slide mechanism are disclosed in Korean Utility Model Registration No. 20-0308165 (announced March 19, 2003), and Korean Patent Publication No. 10-2004-0104358. Publication (published Dec. 10, 2004), Republic of Korea Patent Publication No. 10-2005-0029974 (published March 29, 2005), Republic of Korea Patent Publication No. 10-2005-0046519 (May 18, 2005) Publicly disclosed), Korean Patent Application No. 10-2004-0088994 (filed November 03, 2004), and the like.

The common configuration of the semi-automatic slide mechanism disclosed in the above materials allows sliding movement of two slide members in the form of plates or blocks and slidingly joining the two slide members in a 'ring spring', 'torsion spring'. It is connected to an elastic member formed in the form of a tension (coil) spring ', and the other slide member with respect to one slide member is a turning point (critical point) in which the elastic restoring force of the elastic member acts in the opposite direction. By sliding to a point, the slide member is automatically opened or closed by the elastic pressing force of the elastic member.

In addition, conventional examples of a slide-type portable terminal using an automatic slide mechanism are disclosed in Korean Unexamined Patent Publication No. 10-2004-0086951 (published October 13, 2004) and Korean Unexamined Patent Publication No. 10-2005-0141271. (Published May 04, 2005) and the like.

The common configuration of the automatic slide mechanism disclosed in this publication or the like is slidably coupled to two slide members that form a plate or / and a block. One of the two slide members is fixed to the lower body and the other to the upper body. Then, the slide operation is automatically performed by operating at least one of the two slide members by a drive source such as a motor.

Accordingly, the above-mentioned 'semi-automatic slide mechanism' and 'automatic slide mechanism' include two slide members (typically, 'guide' and 'slider' are combined) that are slidably coupled to each other. One is connected to the lower body and the other is connected to the upper body in the same configuration. However, it can be said that the sliding movement of the two slide members is different in that an elastic member is used or otherwise a driving source such as a motor is used.

In the accompanying drawings, a semi-automatic slide mechanism disclosed in Korean Patent Application No. 10-2004-0088994 is shown as an example of the conventional automatic or semi-automatic slide mechanism. The semi-automatic slide mechanism 30a shown in FIG. 2 utilizes the property of being stretched again (restored) when the long tensile coil spring 30 is bent. Specifically, the semi-automatic slide mechanism 30a couples the slide member 50 to the guide member 40 so that linear movement is possible, and connects the tension coil spring 30 to the guide member 40 and the slide member ( 50). In such a semi-automatic slide mechanism 30a, when the guide member 40 is fixed to the lower main body of the terminal and the slide member 50 is fixed to the upper main body of the terminal, the upper main body and the lower main body slide. This is possibly connected. Therefore, when the upper body is pushed upwards or downwards, the tension coil spring 30 is bent at first, and reaches the intermediate point to reach the turning point of elastic pressing force, after which the tension coil spring 30 is again Try to be restored. Therefore, after the upper body is moved up to a certain section, even if no further force is applied, the upper body is automatically moved to the open position or the closed position by the elastic restoring force of the tension coil spring.

As described above, the conventional slide-type portable terminal has the above-mentioned advantages in terms of design and convenience, but in some cases, these advantages hinder the development of a better (convenient) terminal. Also works as.

For example, current mobile phones, PDAs, MP3 players, portable multimedia players, DMB phones, and the like, call functions, digital video recording functions, multimedia recording / playback functions, games, mobile multimedia broadcasting (DMB) service functions, financial settlement functions, home use It is being developed into a so-called 'portable digital composite device' or 'portable multimedia composite device' that includes both remote control and monitoring functions. Therefore, it will be apparent that the portable terminal in the form of a slide should be able to perform all the above functions smoothly. However, the conventional slide-type portable terminal is insufficient to meet all of the above requirements due to its shape limitations. For example, the conventional slide-type portable terminal has a structure in which the upper main body is simply slid up and down with respect to the lower main body, so that the direction in which the LCD screen can be viewed is determined in only one direction. Therefore, when using a function that requires viewing the LCD screen for a long time for the purpose of receiving a DMB broadcast or playing a game, the user should always hold the terminal in his hand for a long time and continuously adjust the LCD screen in front of his or her own stand, or I had to accept the inconvenience of putting it up.

On the contrary, since the folding portable terminal has a structure in which the upper main body can be rotated at a predetermined angle (typically 135 degrees) with respect to the lower main body by connection by a rotary hinge body, such a rotation function can be easily modified or applied. It can be configured to open and stand the upper body with a liquid crystal screen at a necessary angle alone. For example, Korean Patent Application Publication No. 10-2004-077168 (published on September 04, 2004) and Korean Utility Model Registration No. 20-0353084 (announced on June 22, 2004) and the like have a lower body and a lower body. By applying the hinge structure of the upper body, a technique for mounting or stopping the angle of the upper body at a constant angle is disclosed. However, in the technique disclosed in the above-described Korean Patent Publication No. 10-2004-077168, the angle of the liquid crystal screen itself is not changed, but the top body having the liquid crystal screen is tilted and mounted on the lower body. Therefore, when the upper main body is mounted at an angle, there is a disadvantage in that the input keys of the lower main body are covered by the upper main body and cannot be used. In addition, in the technique disclosed in the Republic of Korea Utility Model Registration No. 20-0353084, the existing hinge body connecting the upper body having the LCD screen using the elastic member and the cam 'angle suitable for call' (about 135 degrees ~ 150 degrees), and the upper body is held at an angle of 90 degrees against the force that elastically presses the upper body in the opening direction by a hinge body in which the elastic member and the cam are combined. By providing another fixing device using an elastic member for stopping at an intermediate angle, it is difficult to configure the arrangement of the force between the hinge body and the fixing device. For example, if the elastic force of the elastic member of the fixing device is too weak, it is difficult to stop at the 'intermediate angle', and if the elastic force of the fixing device is too strong, it is set from the 'middle angle' to the 'angle suitable for the call'. It requires too much force to open, so even when opened outside the 'intermediate angle', the inertial force that pushed the upper body is still in operation, causing the upper body to be pushed with a greater force than the 'angle suitable for the call', There are disadvantages such as breakage of the hinge body and the hinge portion of the upper body and the lower body. Apart from these drawbacks, above all, the technologies disclosed in the above two publications are all called "foldable portable terminals," and therefore, there is a limit that cannot maintain the above-mentioned basic advantages or characteristics pursued by the "slide-type terminals." have.

On the other hand, a similar example of the form configured to view the LCD screen of the slide-type portable terminal for a long time is disclosed in Republic of Korea Utility Model Registration No. 20-0363291 (August 1, 2004), Republic of Korea Utility Model Registration No. 20-0378901 ( March 16, 2005).

In the terminal disclosed in Korean Utility Model Registration No. 20-0363291, in order to reduce the phenomenon that electromagnetic waves generated from the LCD screen interfere with the antenna, the lower main body and the upper main body are connected with two supports, and the upper main body is pushed. The upper support itself is inclined slightly by the two support bases in a state spaced apart from the lower support. However, since the upper body is deformed into an unusual shape in which the upper body is spaced apart from the lower body, it cannot be classified as a slide type terminal of a typical meaning in which the upper body slides closely to the lower body. In addition, for this reason it is not possible to enjoy the above-mentioned advantageous characteristics inherent in the traditional slide type terminal. In particular, if the user wants to make a call after opening the upper main body, the upper main body is always spaced apart from the lower main body to form an inclined shape in the end, thereby causing discomfort or inevitability.

In addition, the Utility Model Registration No. 20-0378901 discloses a separate case that can be mounted on a desk or the like by mounting the slide-type terminal. Therefore, in order to view the LCD screen for a long time, there is an inconvenience of carrying the case separately, and when there is no place where the case can be placed, such as when moving, there is a disadvantage that it cannot be used.

The present invention was developed in view of the various conventional circumstances as described above, and an object of the present invention, while retaining the advantages of the slide-type terminal as it is, separately partitioning only the LCD screen portion relative to the upper body to stand at a predetermined angle The present invention provides a slide-type portable terminal capable of standing up a liquid crystal screen, which enables a user to enjoy a content such as a broadcast or a video more conveniently through a liquid crystal screen, and has a simple structure and is convenient to use.

Hereinafter, with reference to the accompanying drawings will be described in detail preferred embodiments of the present invention.

3a and 3b are for explaining the external form of the terminal to be implemented in the slide-type portable terminal according to the present invention.

First, in the terminal according to the present invention shown in FIG. 3A, the lower body 100 and the upper body 200 use one of the known slide mechanisms described above in the up and down directions, similar to a general slide type terminal. Sliding movement is coupled to. The upper main body 200 has a liquid crystal panel unit 250 is divided into compartments and assembled separately. That is, the upper body 200 is formed of a combination of the upper case portion 210 and the liquid crystal panel 250. The liquid crystal panel 250 has a liquid crystal screen 251. The lower main body 100 is provided with various input keys 101.

In the present embodiment, the planar area of the liquid crystal panel 250 is made smaller than the planar area of the upper case 210. In addition, the liquid crystal panel 250 is configured to move and stand in a direction orthogonal to the longitudinal direction of the upper case part 210, that is, in a lateral direction.

To this end, an accommodating groove 211 is formed in the upper case portion 210 of the upper body 200, and the liquid crystal panel unit 250 is inserted into the accommodating groove 211. Here, it is preferable that the surface of the liquid crystal panel unit 250 has a height that matches the surface of the upper case unit 210 in terms of a telephone function or an aesthetic aspect.

The width and depth of the cutout groove 211c are sufficiently formed to push the liquid crystal panel 250b by inserting a user's finger.

6A and 6B schematically illustrate another type of slide-type portable terminal to be implemented in the present invention.

In the present embodiment, the movement and the standing operation of the liquid crystal panel 250c are performed in the longitudinal direction of the upper case part 210c. Also in this case, the liquid crystal screen 251 can be enjoyed as a long screen.

However, in the present embodiment, the upper main body 200 is divided into two parts, the upper case part 210c and the liquid crystal panel part 250c, up and down, so as to have a plane area of the same size. At the same time, the liquid crystal panel 250c is disposed on the upper surface of the upper case 210c in a simple seated form. Here, it becomes a natural and preferable form that the various function keys 212 and the receiver 213 are arranged on the upper surface of the liquid crystal panel unit 250c other than the liquid crystal screen 251.

(Example 1)

7A to 7D show a first preferred embodiment of the slide-type portable terminal of the present invention.

As shown in Figure 7a to 7d, the slide-type portable terminal of the present invention, the lower main body 100 and the upper main body 200 is the sliding movement in the longitudinal direction with each other in the same way as a conventional slide type terminal conventional Possibly combined. In addition, according to the present invention, the upper main body 200 is divided into an upper case part 210 and a liquid crystal panel part 250. The liquid crystal panel 250 has a liquid crystal screen 251. The liquid crystal panel 250 is accommodated in the accommodation groove 211 of the upper case 210. As described above, the surface of the liquid crystal panel 250 is formed to be coplanar with the surface of the upper case 210.

The liquid crystal panel unit 250 is pivotally coupled to one end (right side in the drawing) of the lower end of the liquid crystal panel 250 so as to be slid by the linear movement guide 300 and to be the center of rotation. In addition, the connection link 400a connects the upper case part 210 and the liquid crystal panel part 250. As the liquid crystal panel unit 250 slides, the connection link 400a gradually raises the opposite side of the pivot coupling unit of the liquid crystal panel unit 250 so that the liquid crystal panel unit 250 is erected.

Therefore, the upper case part 210 forming the upper main body 200 is opened and closed by sliding upward and downward with respect to the lower main body 100. In addition, the liquid crystal panel 250 having the liquid crystal display 251 may have a first position overlapping the upper case portion 210 by a combined movement of the linear motion guide 300 and the connection link 400a. (A position closed in a horizontal state) and a second position (upright position) that is erected at an angle from the upper case portion 210.

In the present embodiment, the linear motion guide 300 specifically includes a guide rail 310 and a sliding block 320. The guide rail 310 is fixed to the upper case portion 210. The sliding block 320 is slidably coupled to the guide rail 310. In addition, one lower end of the liquid crystal panel 250 is pivotally coupled to the sliding block 320 via a pivot shaft 252.

In the present embodiment, when the liquid crystal panel 250 is in the above-described first and second positions, the sliding block 320 is stopped, and when a predetermined force is applied again, the first and second positions are applied. It further includes an elastic locking mechanism 330 to escape.

The elastic locking mechanism 330 according to the present embodiment includes an opening groove 321 formed in the sliding block 320, an elastic member 322 inserted into the opening groove 321, and the elastic member ( And a ball 323 seated at the tip of 322. In addition, the guide rail 310 is formed with a locking groove 311 having a size to which the ball 323 can be fitted in a predetermined amount at the point to be the first position and the second position. According to this configuration, the ball 323 is stopped by the locking groove 311 by the elastic pressing force of the elastic member 322, the movement of the sliding block 320 is stopped. In addition, when the sliding block 320 is pushed beyond the elastic pressing force of the elastic member 322, the elastic member 322 is compressed, the ball 323 can come out of the locking groove 311.

Here, the latching grooves 311 may be formed at various points corresponding to angles at which the liquid crystal panel 250 is to be stopped, although not shown in the drawings as well as the first and second positions. In this way, the liquid crystal panel 250 can be stopped at various angles according to the user's taste or convenience.

On the other hand, the connection link 400a, the guide groove 253 and the rotation bar 410. The guide groove 253 is formed in the liquid crystal panel unit 250 in a predetermined length along its moving direction. The pivoting bar 410 is pivotally coupled to one end of the pivot bar 411 in the moving direction of the liquid crystal panel 250 by a pivot shaft 411, and the other end thereof is the liquid crystal panel part. The sliding groove is coupled to the guide groove 253 of the 250 through the guide shaft 412.

A standing process of the liquid crystal screen 251 in the slide-type portable terminal according to the first embodiment of the present invention made as described above will be described with reference to FIGS. 8A to 8D. Since the upper and lower sliding operations of the upper main body 200 with respect to the lower main body 10 have already been described and are the same as the known ones, the upper case 200 of the upper main body 200, which is a main part of the present invention, is described here. Only the moving and standing processes of the liquid crystal panel unit 250 will be described.

First, in FIG. 8A, the liquid crystal panel 250 having the liquid crystal display 251 overlaps the upper case 210 (substantially inside the receiving groove 211). In addition, this state is a state suitable for use while moving the upper main body 200 up and down with respect to the lower main body 100 as in the conventional general slide type terminal. In this state, the ball 323 of the sliding block 320 is partially inserted into the engaging groove 311 formed at the first position of the guide rail 310 by the elastic pressing force of the elastic member 322.

In this state, when the liquid crystal display 251 stands up, as shown in FIG. 8B, one end (right end in the drawing) of the liquid crystal panel 250 which is pivotally coupled by the pivot axis 252 is shown. Push in the opposite direction (left in drawing).

Then, the ball 323 inserted into the locking groove 311 of the guide rail 310 receives the lifting force to leave the locking groove 311 while compressing the elastic member 322, and thus the sliding block 320 is The left side moves along the guide rail 310. At this time, since the lower end of the liquid crystal panel unit 250 is pivotally coupled to the sliding block 320, the rotation is freely maintained with the sliding block 320. In addition, the liquid crystal panel unit 250 is connected to the upper case unit 210 by the connection link 400a. Therefore, in response to the liquid crystal panel unit 250 moving together with the sliding block 320, the pivoting bar 410 of the connection link 400a is about the pivot shaft 411 with respect to the upper case 210. Rotation is performed and the guide shaft 412 moves along the guide groove 253 of the liquid crystal panel 250 to raise the tip of the liquid crystal panel 250. The lower end rotates about the pivot shaft 252 while moving along the sliding block 320, and at the same time, the front end thereof is lifted by the pivoting bar 410, whereby the liquid crystal panel 250 is erected.

When the liquid crystal panel unit 250 is moved to the state of FIG. 8D through the state of FIG. 8C, the liquid crystal panel unit 250 is erected to have a maximum slope determined in the initial design.

Then, the sliding block 320 is stopped at the second position by the elastic pressing force of the elastic member 322, and thus the liquid crystal panel 250 is also stopped at the second position. When the terminal is placed on a horizontal surface of a desk or the floor, the liquid crystal screen 251 of the liquid crystal panel 250, which is erected in the above-described operation, faces the user's gaze and thus can be viewed more comfortably. In addition, when the terminal is held by hand, the LCD screen 251 may be faced even when the arm is comfortably held in a horizontal state. Therefore, the conventional inconvenience of intentionally tilting the entire terminal to make eye contact with the LCD screen 251. The box disappears.

In order to lay down the liquid crystal display 251, which is viewed as described above, the upper end portion of the liquid crystal panel 250, which is standing at the second position, is pressed above the elastic pressing force of the elastic member 322. Then, the ball 323 inserted into the locking groove 311 of the guide rail 310 receives the lifting force and compresses the elastic member 322 to escape the locking groove 311 corresponding to the second position from the second position. The movement starts towards the first position. Subsequently, the sliding block 320 and the connection link 400a move in the reverse order of the 'standing order' described above, so that the liquid crystal panel 250 is laid down, and is horizontally positioned in the receiving groove 211 of the upper case part 210. It is stored.

(Example 4)

13A to 13C show a slide-type portable terminal according to a fourth embodiment of the present invention.

In the present exemplary embodiment, the movement of the liquid crystal panel 250 is implemented by using the previously known slide mechanism. Among the slide mechanisms described above, the semi-automatic slide mechanism is disclosed in Republic of Korea Utility Model Registration No. 20-0308165, Republic of Korea Patent Publication No. 10-2004-0104358, Republic of Korea Patent Publication No. 10-2005-0029974, Republic of Korea It has been introduced that there are a variety of forms, such as Publication No. 10-2005-0046519, Republic of Korea Patent Application No. 10-2004-0088994. In addition, such a semi-automatic slide mechanism, the two slide members in the form of a plate or / and block form to be slidably coupled, the two slide members' ring spring ',' torsion spring 'tension (coil) spring' Connected to an elastic member in the form of a back, and slides the other slide member with respect to one slide member to a point where the elastic restoring force of the elastic member becomes a turning point (critical point) acting in the opposite direction, the The slide member is automatically opened or closed by the elastic pressing force of the elastic member.

In addition, the automatic slide mechanism connects two slide members that are slidably coupled to each other, that is, a 'guide' and a 'slider', one of which is connected to the lower main body, and the other of which is connected to the upper main body and slides thereof. It described that the movement is made automatically by using a drive source such as a motor.

In the present embodiment, the use of the semi-automatic slide mechanism 30a shown in FIG. 2 is described as an example among the above-mentioned various semi-automatic slide mechanisms. In principle, they are all the same, so they can all be applied in the same way.

For example, the guide member and the slide member of the automatic slide mechanism or the semi-automatic slide mechanism are implemented by fixing the guide member to the upper case portion 210 and pivotally coupling the slide member to the liquid crystal panel unit 250.

That is, such a slide mechanism can be said to replace the linear motion guide 300 and the elastic locking mechanism 330 in the above-described first, second, and third embodiments. However, the use of the semi-automatic slide mechanism adds the convenience of automatically moving further when the movement of the liquid crystal panel portion exceeds a certain range by an elastic member provided to have a turning point of restoring force. On the other hand, the use of the automatic slide mechanism adds the convenience that the movement of the liquid crystal panel portion is automatically performed by a drive source such as a motor.

As shown in FIGS. 13A to 13C, the guide member 40 of the slide mechanism 30a described above is fixed to the bottom of the receiving groove 211 of the upper case part 210 by means of a screw 41 or the like. In addition, one end of the liquid crystal panel unit 250 is pivotally coupled to the slide member 50 of the slide mechanism 30a. In the embodiment shown in the drawings, the pivot coupling is provided with a fastener 51 on the upper surface of the slide member 50, the liquid crystal panel 250 is inserted into the fitting groove 51 and the insertion groove loosely. 254 is formed, and the support member 51 is inserted into the insertion groove 254 and then coupled to the hinge shaft 52. Therefore, the liquid crystal panel unit 250 can rotate about the hinge axis 52 with respect to the slide member 50. In addition, the guide member 40 and the slide member 50 are connected by the tension coil spring 30 (in the case of automatic connection to a drive source such as a motor). The movement range of the slide member 50 with respect to the guide member 40 is set according to the size of the standing angle of the liquid crystal panel 250.

The connecting link in the present embodiment uses the same connecting link as the connecting link 400a in the first embodiment. That is, the connection link 400a may include a guide groove 253 formed at a predetermined length in the liquid crystal panel unit 250 along the moving direction thereof, and one end thereof may be pivoted on the upper case portion 210. It is pivotally coupled in the movement direction of the liquid crystal panel unit 250 by the other end thereof, the other end thereof is coupled to the guide groove 253 of the liquid crystal panel unit 250 through the guide shaft 412 to enable the sliding movement It is configured to include a rotating bar 410.

In the slide-type portable terminal according to the fourth embodiment of the present invention, when the liquid crystal panel unit 250 is pushed in the moving direction to stand the liquid crystal panel unit 250, the liquid crystal panel unit 250 is hinged ( The slide member 50, which is pivotally coupled by 52, moves along the guide member 40. In the moving process, the tension coil spring 30 is bent, and when the elastic transition point (threshold point) passes, the liquid crystal panel 250 automatically moves to the second position by the elastic restoring force of the tension coil spring 30. Will move. In this case, as described in detail through the first embodiment, the free end of the liquid crystal panel unit 250 is raised by the movement of the liquid crystal panel unit 250 by the action of the connection link 400a. You can do it.

On the contrary, the operation of closing the liquid crystal panel 250 toward the upper case 210 also works in the same manner. That is, when the upper end of the standing liquid crystal panel 250 is pressed, the slide member 50 in which the liquid crystal panel 250 is pivotally coupled by the hinge axis 52 is formed along the guide member 40. It will move towards the location. In the moving process, the tension coil spring 30 is bent again, and when the elastic transition point (threshold point) passes, the liquid crystal panel unit 250 automatically moves to the first position by the elastic restoring force of the tension coil spring 30. Will move to. Therefore, as described in detail through the first embodiment, the free end of the liquid crystal panel 250 is lowered according to the action of the connection link 400a and the movement of the liquid crystal panel 250. It can be stored in a horizontal state in the receiving groove 211 of the unit 210.
