It is a cross section. 6A is a partial perspective view showing an LCD accommodating panel of the liquid crystal panel constituting the mobile terminal of the present invention, and FIG. 6B is a partial perspective view showing one side hinge of the liquid crystal panel constituting the mobile terminal of the present invention.

As shown therein, the mobile terminal according to the present invention has a battery (not shown), and includes a keypad 110 having an input button such as a number key, a power key, and a function key, and the inside of the keypad 110. A main body 100 including a circuit board (not shown) for converting an input signal into a circuit signal and a microphone 120 positioned at a lower end thereof; A speaker 201 provided at the top and a liquid crystal display 202 for displaying data input from the keypad 110 of the main body 100, the sliding end of the sliding end on the upper surface of the main body 100, It includes a liquid crystal panel 200 which is a sliding moving part to rotate in.

The configuration of the body 100 and the liquid crystal panel 200 will be described in more detail.

First, the main body 100 is protruded to a predetermined degree upward on both side walls thereof to form a protruding bent wall 130, and the guide rail 212 of the liquid crystal panel 200 to be described later is formed on the inner surface of the protruding wall 130. Guide grooves 131 are inserted and guided.

On the inner wall surface of the rear end of the guide groove 131, as shown in Figure 4a, a stopper portion 132 for limiting the movement of the guide piece 223 of the hinge 222 to be described later protrudes. The guide piece 223 is formed in the longitudinal direction of the hinge portion 220, but may be formed in the thickness direction.

At this time, the stop of the stopper 132 is guided through the guide rail 212 of the liquid crystal panel 200 to be described later, the guide piece 223 of the hinge cam 222 so as to catch the guide groove 131 It protrudes from the wall.

The inner surface of the front guide groove 131 of the stopper portion 132 is formed with a round portion 133 protruding, the center portion is formed with a seating groove 134 on which the guide piece 223 can be seated.

Here, the stopper portion 132 may protrude from the lower surface of the rear end of the guide groove 131, as shown in Figure 4b. Accordingly, the thickness H of the guide piece 223 of the hinge cam 222 described later is equal to the height H 'of the guide groove 131, and the thickness h of the guide rail 212 is the guide groove. It is formed smaller than the height W from the upper surface of 131 to the upper surface of the stopper 132.

At this time, a round portion protrudes from the inner surface of the front guide groove 131 of the stopper portion 132, and a seating groove 134 on which the guide piece 223 is seated is formed at the center portion thereof.

1.1 Hinge configuration and electrical and circuit connection using cables

On one side of the main body 100 is formed a cable movement passage 150 in which a film-type cable 140 (see FIG. 5A) is connected to a circuit board (not shown) in the main body 100. Since the main body 100 and the liquid crystal panel 200 are referred to as a convenience division, the cable movement path 150 may be formed on the liquid crystal panel 200 side.

In this case, as shown in FIG. 11, the cable movement passage 150 may be formed by extending in front of the main body 100 to sufficiently secure the accommodation and movement space of the cable 140.

The cable movement passage 150 is drawn out from the cable movement passage 150 on the upper surface of the main body 100 on which the cable movement passage 150 is formed, and preferably on the upper surface of the main body 100 adjacent to the wall surface 131a on which the guide groove 131 is formed. A cable moving groove 135 is formed to allow the cable 140 connected to the LCD module (not shown) of the panel 200 to move together when the liquid crystal panel 200 moves, so that the projection wall 130 It is formed inward from the vertical extension of the bent end.

In other words, by taking a form similar to that of FIG. 5D, it is desirable to take a structure in which the cable 140 is concealed without being visible to the naked eye even in the sliding expansion. In addition, as shown in FIG. 5D, the groove 160 and the protrusion 260 for suppressing the flow in the left and right directions may be placed on one side or both sides to increase the robustness of the terminal. Similarly, it is also possible to put the shapes 161 and 261 of the locking step in FIG. 5D on one side or both sides.

As shown in FIGS. 10 and 12, the cable 140 positioned in the cable movement path 150 has been folded as the liquid crystal panel 200 moves in the direction of the arrow while being folded in the left and right zigzag. It can be installed to move together while unfolding in the cable moving passage (150). In particular, as shown in FIG. 12, when the cable movement passage 150 extends downward from the side of the terminal, even when the terminal is slid and folded, it is possible to sufficiently secure a space in which the cable can be accommodated.

In addition, another installation form of the cable 140, as shown in Figure 13a and 13b, may be installed in a state in which the upper and lower double nested in the cable movement passage 150 of the main body 100.

The liquid crystal panel 200 accommodates an LCD module (not shown) and has a hinge portion 211 at one end thereof, and a guide rail guided along guide grooves 131 of the main body 100 at lower sides of both outer walls. The LCD accommodating panel 210 having the 212 formed therein, and hinge parts 220 respectively coupled to both sides of the hinge part 211 of the LCD accommodating panel 210.

The hinge portion 211 of the LCD accommodating panel 210 has a space therein, and a cylindrical protrusion 213 is formed at one center portion of the outer surface of the hinge portion 211 to communicate with the inner space, and at the center portion of the other outer surface. As illustrated in FIG. 5C, an end portion 214a of the conventional hinge cam module 214 installed at the other side thereof is protruded. The hinge cam module 214 serves to change the elasticity of the straight direction of the spring that the hinge cam module has to the elasticity of the rotation direction through the cam structure.

The hinge portion 220 includes a hinge 222 which is formed integrally at both ends of the connecting piece 221 and has a space therein, and the inner side of the hinge 222 has a central portion of the hinge portion 211. A connecting hole 222a is formed to allow the cylindrical protrusion 213 to be rotatably inserted, and an end portion of the hinge cam module 214 installed at the other side of the hinge portion 211 is formed at the central portion of the inner side of the hinge 222. A fixing hole 222b into which 214a is inserted and fixed is formed. In addition, a cable through hole 222c through which the cable 140 may pass is formed at the bottom surface of the one hinge 222.

Although the cable 140 may pass through the structure as shown in FIG. 6B, but the cable 140 remains stable even when the cable 140 is rotated by 180 degrees after the sliding expansion, the hinge parts 220 and 222 may be disposed as shown in FIG. 6C. It is desirable to have a space 224 in which the cable is received. In Figure 6c 225 is a conceptual representation of the axis of rotation of the hinge. In FIG. 6C, the 224a is indicated by a hidden line, which means that the space 224 in which the cable is accommodated is hidden from the rear side rather than seen from the front side. In Fig. 6C, i, j, k, are not particularly meaningful lengths, and may be appropriately configured. In FIG. 6C, j> l (L means the radius to the rotation axis in lowercase letters), k> l is to ensure a sufficient space to accommodate the cable, but is not necessarily so.

FIG. 6D is a plan view showing that the liquid crystal panel 200 is divided into two parts, the LCD accommodating panel 210 and the hinge portion 220. In FIG. 6D, the lengths of h, h ', and h' 'may be appropriately configured. In order for the hinge portion 222 to rotate smoothly in FIG. 6D, it is preferable that the three sides are circular as shown in 222 partial cross-sectional view 1, but at least have a chamfered structure with a length of h '' as in 222 partial cross-sectional view 2. .

Instead of constructing a hinge directly between the main body 100 and the liquid crystal panel 200, the LCD housing panel 210, the hinge 200, which is enlarged by sliding the portion 200 as illustrated in FIGS. 2 and 6A through 6D. Configuring the hinge into two parts of the branch 220 is one of the important parts of the present invention that provides the firmness of the hinge configuration.

Accordingly, the cable 140 drawn out from the cable moving passage 150 passes through the cable moving groove 135 of the main body 100 to allow the cable passage hole 222c and the cylindrical protrusion 213 of the LCD accommodating panel 210. And it is connected to the LCD module accommodated in the LCD receiving panel 210 via the hinge portion 211. The cable 140 connecting the main body 100 and the liquid crystal panel 200 to pass through the rotation axis of the hinge provides a structure in which the cable is not subjected to pressure even if the liquid crystal panel is rotated 180 degrees after sliding expansion. This applies to the “all” case of electrically connecting two hinged objects.

Guide pieces that move along the guide grooves 131 of the main body 100 on the outer side surfaces of the both side hinges 222, have a cross section identical to the cross-sectional shape of the guide grooves 131, and have rounded ends. 223 is formed.

Here, the guide piece 223 of the hinge 222 is formed in the same extension line as the guide rail 212 when the LCD receiving panel 210 is coupled.

At this time, when the degree of protrusion of the guide piece 223 is T and the degree of protrusion of the guide rail 212 is t, the T is larger than t. In addition, the stopper 132 formed at the end of the guide groove 131 of the main body 100 protrudes from the inner surface of the guide groove 131 so that the guide rail 212 passes and the guide piece 223 abuts. .

Hereinafter, the cable connection configuration for connecting the main body 100 and the liquid crystal panel 200 in a circuit will be described in more detail.

As shown in the drawing, the hinge portion 211 of the LCD accommodating panel 210, the cylindrical projection 213 is inserted into the connecting hole 222a of the hinge 222, withdrawal from the main circuit board 100 The cable 140 passes through the cable through hole 222c of the hinge 222, the cylindrical projection 213 of the LCD receiving panel 210 and the hinge portion 211 in order to be connected to the LCD module.

In this case, the cable 140 has a sufficient length such that the liquid crystal panel 200 does not restrict sliding movement on the main body 100.

1.2 Fixation using flexible locking member

On the other hand, when the liquid crystal panel 200 is slid in the main body 100, a predetermined point, for example, the liquid crystal panel 200 is slid to move to expose only the function key button to a button or a limited button in use It may be provided with a locking means 300 so that movement can be limited at the point to use only. The locking means is applicable to any means.

This will be described with reference to FIG. 7, and FIG. 7 is a cross-sectional view illustrating a locking means of the mobile terminal according to the present invention.

As shown therein, the groove 310 is formed at a predetermined point of the guide groove 131 of the main body 100, that is, the front end, the rear end, or the center, and the groove 310 has a mixture of rubber or rubber and plastic. A flexible locking member 320 of a similar material is inserted and fixed, and one side of the flexible locking member 320 is provided with an exposed portion 321 protruding to a predetermined level from the plane of the groove 310. This flexible locking member will also be referred to as "restoration protrusion" for convenience.

The guide rail 212 of the liquid crystal panel 200 corresponding to the groove 310 is provided with a groove 330 corresponding to the outer surface shape of the exposed portion 321 of the flexible catching member 320.

At this time, the longitudinal front and rear portions of the groove 330 may be formed in an oblique or round shape so as to soften the guide of the locking member 320. See FIG. 14H. In addition, as shown in FIG. 14I, at least 1/2 of the flexible locking member having a ball shape may be included in a surface on which the locking member is fixed. As shown in FIGS. 14I and 14J, if the flexible locking member is not completely fixed but simply stays in the object including the locking member, the detachable object may be easily attached due to the fluidity.

Therefore, while the liquid crystal panel 200 moves along the guide groove 131 of the main body 100, a locking operation that may be caught at a predetermined point is performed.

In this case, the groove 310 of the guide groove 131 of the main body 100 may be formed so as to correspond to the outer shape of the hook member 320 is not exposed, the locking member 320 is a groove ( 310, more firmly fixed.

Here, the locking means 300 may be formed on any side of both sides of the main body 100 and the liquid crystal panel 200 in contact with each other without having to be formed in the guide rail and the guide groove.

The use of a flexible locking member made of rubber or rubber-like material can provide a fixing effect without employing a complicated structure such as a spring. The rubber-like material does not age due to wear and fine flow. It is an advantage that can be suppressed. In the interference fit method using the flexibility of the plastic material, there are disadvantages such as not being able to suppress even fine flow, aging due to wear. This can be applied to "all" cases (including non-sliding movements) where the force acts at right angles to the direction of motion to exert a fixed force. For example, a similar structure may be applied to the case in which the part of the circle shown in FIG. 4A and the terminal in FIG. 8 are fixed after expansion, and the case is not coupled in a sliding manner as shown in FIG. 14K.

1.3 Partial Expansion of the Terminal

As shown in Fig. 8, it is possible to use the mobile terminal while exposing only some function buttons of the mobile terminal during sliding expansion. Using some necessary functions (eg, menu moving function and selecting function) in a state in which only a part of the terminal is extended will provide convenience in using a menu type service provided by the current mobile carrier. This is called sliding "partial expansion" or sliding "partial expansion" for convenience. The locking means for stopping after the partial expansion can use any method.

In FIG. 8, the movement button is placed on the lower side of the numeric keypad rather than on the upper side, which can be found to be particularly useful when the sliding part is expanded.

1.4 Realization of Currency Angle (Reflection Angle)

As shown in Fig. 3 and Fig. 11a, after the sliding is completed, it is possible to automatically achieve a call angle or reflection angle (an angle similar to that of the current folder or flip type terminal). This may refer to the flip and the terminal body forming a predetermined angle when the flip is opened in the current flip-type terminal, and the ridge portion 214b and the valley portion of the hinge cam module (214 in FIG. 5C) at a predetermined reflection angle. The hinge can be configured so that the (214c) is in an engaged state (for convenience, referred to as a "hinge cam equilibrium state").

Furthermore, in order to prevent it from being easily detached with a constant support force in the reflection angle state, in addition to the ridge portion 214b and the valley portion 214c of the hinge cam module 214, the “small ridge portion and the valley portion 214d or 214e shape) ”May be placed as in FIG. 6E.

1.5 Auxiliary Liquid Crystal

Meanwhile, the auxiliary liquid crystal screen 202 ′ may be provided on the other side of the liquid crystal panel 200 where the main liquid crystal screen 202 is located.

At this time, the auxiliary liquid crystal 202 ′ is provided on the back of the main liquid crystal 202, and as shown in FIG. 9, the auxiliary liquid crystal screen 202 ′ is not overlapped with a portion where the main liquid crystal screen 202 is installed. Can be installed on Therefore, when the liquid crystal panel 200 is folded to the end of the main body 100 in the state in which the main liquid crystal screen 202 is exposed to the outside, and then folded in a folding manner, the auxiliary liquid crystal screen 202 'is exposed to the outside. It becomes a state.

Therefore, since the LCD screens are not overlapped, the thickness of the LCD screen can be greatly reduced compared to the existing dual folder mobile terminal (terminal sold in Korea and a terminal adopting liquid crystal on the outer surface of the folding model). I would have to.

1.6 Side Screw Assembly

On the other hand, the assembly of the liquid crystal panel and the main body 100 of the present invention, as shown in Figure 15, the mounting groove in which one surface is opened to the outside on a predetermined side wall formed with the guide rail 213 of the housing case accommodating the LCD module, etc. A 501 is formed, and a screw groove hole 501 'through which the screw 500 can be coupled is formed in the inner wall of the mounting recess 501 opposite to the open surface. The cover covering the upper part of the housing case is formed with a coupling protrusion 502 seated in the mounting groove 501 of the housing case on a predetermined side wall corresponding to the mounting groove 501, the coupling protrusion 502 is A thread through hole 502 ′ is formed through which the screw 500 can pass.

At this time, the outer side of the threaded through hole 502 'of the overlapping protrusion 502 has an extension portion in which the screw head is seated so as to have the same plane as the outer surface of the coupling protrusion 502 when the screw 500 is engaged.

In this way, the assembly of the liquid crystal panel is made through the side of the liquid crystal panel using a screw. The screw assembly method through the side of the liquid crystal panel may be equally applicable to the assembly method of the main body. This is called "side screw assembly method" for convenience, so that the screw is not exposed to the front of the terminal. This will be particularly helpful when the battery is mounted on the side, such as in an earlier application.

1.7 Terminal Operation

The operation of the mobile terminal having the sliding liquid crystal panel according to the present invention configured as described above will be described with reference to FIGS. 10 and 11A to 11C.

Likewise, when the liquid crystal panel 200 is temporarily restrained at a predetermined point during the sliding movement by being seated in the groove 330 formed in the guide rail 212 of the liquid crystal panel 200, the force is continuously applied in the movement direction as described above. Proceed with the same sliding action.

In the above description, the liquid crystal panel in which the LCD module is installed in the sliding component has been described, but on the contrary, the LCD module may be formed on the main body, and a number key or a function key may be installed in the sliding component.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

2. Combine optical mouse function in mobile terminal

The notebook PC already has a mouse function. Optical mice are now widely used in desktop PCs. Optical mice can be employed in notebook PCs and other mobile terminals. 16A shows the movement of the cursor according to the movement of the current optical mouse. Fig. 16B shows the direction of movement of the cursor according to the movement of the hand in the light sensing unit when the optical mouse is turned upside down. The hand acts as a mouse pad. In the left and right directions, the cursor moves as the hand moves, but in the up and down directions, the cursor moves as opposed to the hand movement.

In order to operate the mouse with the optical mouse module mounted on the terminal and the optical sensing unit exposed to the surface of the terminal as in FIG. 16B, the optical mouse is made to coincide with the direction of movement of the hand and the cursor as in FIG. All you have to do is design and install the module. Incorporating an optical mouse module in a mobile terminal that requires mouse functionality will help miniaturize the terminal.

As described above, the mobile terminal according to the present invention allows the liquid crystal panel having a liquid crystal screen to slide on the main body of the terminal and to be folded like a general folding type when the movement is completed, thereby allowing liquid crystals according to the user's convenience. There is an effect that can increase the user's convenience by allowing the screen to be used in an exposed state or in an unexposed state.

In addition, the present invention has the effect that can be provided with the maximum liquid crystal screen compared to the size of the terminal.
