1 is a view for explaining an operation of a mobile terminal.

As shown in the drawing, the mobile terminal 100 may be in a form of foldable body BD. For example, it means that one end and the other end of the body BD may be folded in a close and / or mutually contacting manner. At least one side of the body (BD) may be provided with a display (D).

The display D may be formed substantially on the entire surface of at least one surface of the body BD. This may be different from the conventional folder phone. In other words, unlike the conventional folder phone in which the display area is present in a part of one surface, the mobile terminal 100 according to the embodiment of the present invention has one display positioned to one end and the other end of the body BD .

The display D may be in a flexible form. That is, if the body BD is folded, it means that the display D can also be folded accordingly. This may be a different feature from the conventional display. The flexible display D may be located in substantially the entire area of at least one side of the body BD.

The mobile terminal 100 may have a certain thickness. That is, it means that it may have a thickness of T in the Z direction. The thickness of the mobile terminal 100 may be the sum of the Z directions of the mobile terminal 100 including the body BD and the display D,

The mobile terminal 100 may be in a first state S1 or a first state S2.

The first state S1 may be a state in which the body BD is extended. For example, if the body BD is divided into a plurality of regions, a state in which the bodies BD divided into a plurality of regions are arranged on the same plane may be the first state S1. In the first state S1, the mobile terminal 100 may be viewed as a stick.

The second state S2 may be a state in which the body BD is bent. For example, a state in which one region of a body BD divided into a plurality of regions is folded into another region may be a second state S2. In the second state S2, the length of the mobile terminal 100 can be seen to be about half.

In the process of bending from the first state S1 to the second state S2, a difference in length may occur between the inner side surface and the outer side surface of the body BD. The difference in length may occur due to the thickness T of the mobile terminal 100. [ That is, due to the thickness T, a difference may occur between the first radius R1, which is the radius to the inner surface of the body BD, and the second radius R2, which is the radius to the outer surface of the body BD. The length of the outer surface of the body BD may be longer than the length of the inner surface of the body BD in the second state in which the body BD is folded due to the difference between the first and second radii R1 and R2. If the length of the outer surface of the body BD is longer than the length of the inner surface of the body BD, wrinkles may occur in the display D on the inner side of the body BD when the body BD is folded.

In the second state S2, the first radius R1 of the inner side of the body BD may be required. This can be clearly understood in view of the fact that the display D positioned on the inner side of the body BD may be damaged when the display D is folded flat. Therefore, the mobile terminal 100 may need a structure for maintaining the first radius R1 in the body in the second state.

2 to 4 are views showing a mobile terminal according to an embodiment of the present invention.

As shown in these drawings, the mobile terminal 100 according to the embodiment of the present invention can be configured to be in any one of the first state and the second state and / or the middle state of the first and second states have.

FIG. 2 shows front and rear views when the mobile terminal 100 according to the embodiment of the present invention is in the first state. As shown, the body 230 of the mobile terminal 100 may include a first body 210 and a second body 220. The display D may be located on the first and second bodies 210 and 220. The display D may be positioned on one of the first and second bodies 210 and 220 continuously.

3 (a) illustrates a situation in which the mobile terminal 100 according to the embodiment of the present invention is in the middle state of the first and second states. As shown in the figure, the first and second bodies 210 and 220 of the mobile terminal 100 may be in a third state bent at a predetermined angle. The change from the first state to the second state and / or the fixation to the third state may be via the hinge assembly L connecting the first and second bodies 210, 220.

FIG. 3 (b) illustrates a situation where the mobile terminal 100 according to the embodiment of the present invention is in the second state. The mobile terminal 100 may be in a second state in which the first and second bodies 210 and 220 are rotated about the hinge assembly L. [ In the second state, the first and second bodies 210 and 220 may be in a superimposed state. In the second state, the display D may be located in the inner region of the first and second bodies 210,220.

4 shows the position of the hinge assembly L included in the mobile terminal 100 according to an embodiment of the present invention. As shown, the hinge assembly L may be positioned between the first and second bodies 210 and 220.

The substrate P may be positioned inside the mobile terminal 100. The substrate P may be positioned on any one of the first and second bodies 210 and 220. For example, the substrate P may be located on the first body 210.

The battery B may be located inside the mobile terminal 100. The battery B may be located in the other of the first and second bodies 210 and 220. That is, the battery B may be located in a different body than the substrate P. For example, the battery B may be located on the second body 220.

A plurality of sound output units O1 and O2 and / or a plurality of microphones M1 and M2 may be disposed inside the mobile terminal 100. For example, one end region and the other end region of the first and second bodies 210 and 220.

The hinge assembly L may be located inside the mobile terminal 100. The hinge assembly L may connect the first and second bodies 210 and 220. The hinge assembly L may be positioned in the middle of the first and second bodies 210 and 220.

The hinge assembly L may be connected to the first and second bodies 210 and 220 through a support plate SP connected to both sides.

5 and 6 are views showing a change of a display according to an operation of the mobile terminal according to the present invention.

5 (a), the display D is positioned on the hinge assembly L in the first state, with the sides on the first and second bodies 210 and 220 have.

The display D can maintain a flat shape in the first state. That is, the display D is not bent. In this case, the upper surface of the support plate SP connected to the hinge assembly L may have the same height as the upper surface of the hinge assembly L and the first and second bodies 210 and 220. Accordingly, the user can concentrate more on the flat display D screen.

Alternatively, as shown in FIG. 5 (b), at least a portion of the display D may move from the second state to a recessed area (RA). The recessed area RA can be formed by moving the support plate SP to the inside of the body 230. At least a portion of the display D may have a constant curvature DR and may move into the recessed area RA. Thus, the difference in length between the inner side surface and the outer side surface of the body 230 can be compensated for.

The support plate SP can slide to the inside of the body 230 while the mobile terminal 100 changes from the first state to the second state. The display D supported by the support plate SP can be recessed with a certain radius DR inside the body 230 together with the support plate SP.

Only the center portion of the hinge assembly L among the recessed regions RA can be attached to the display D as shown in Fig. That is, the portion of the depression area RA where the display D is bent in the second state may not be attached to the display D.

Since the center of the hinge assembly L is attached to the display D, the display D may be recessed inward to have a certain radius DR while changing from the first state to the second state. If the center portion of the hinge assembly L is not attached to the display D, it can be changed into a random shape without having a radius. In this case, the display D may be twisted and tangled inside. Further, a wrinkle can be formed on the display D.

The region except for the depression region RA can maintain the display D in a flat state in the second state. Accordingly, the body 230 and the display D can be attached to the region excluding the depression region RA.

7 to 12 are views showing the structure of a mobile terminal 100 according to an embodiment of the present invention.

The hinge assembly L may be connected to the first and second bodies 210 and 220 as shown in FIG. The hinge assembly L may be connected to the link fixing portion LF fixed to the first and second bodies 210 and 220 by the link connection portion LC. The link connecting portion LC and the link fixing portion LF may be located at both ends and a central portion of the hinge assembly L. [ However, the present invention is not limited thereto, and the link connecting portion LC and the link fixing portion LF may be located at various portions so as not to be separated from the first and second bodies 210 and 220.

The link connection portion LC can be attached to the lower surface of the support plate SP. The link connecting portion LC can slide inward of the body when changing from the first state to the second state. Thereby, the support plate SP is also guided by the link connection LC, and can slide inward when changing from the first state to the second state.

The frame cover FC can be positioned at the lower end of the hinge region HA. The frame cover FC can shield the link fixing portion LF and the hinge assembly L so that at least a part thereof is not exposed at the rear face. The frame cover FC can engage with the body 230 through at least one screw. Accordingly, the link fixing portion LF located between the frame cover FC and the body 230 can be prevented from being separated.

The frame cover FC may be formed with a groove GR at a portion corresponding to the link connection portion LC. The groove GR may be a space in which the link connecting portion LC slides inward from the second state. That is, it means that the link link LC can be located in the groove GR in the second state.

The back cover BC may be positioned on the rear surface of the body 230 and the frame cover FC. The back cover BC can shield the rear surface and the side surface of the body 230. [ The back cover BC may have a curvature at its tip. Accordingly, the user can feel that the appearance is neat.

As shown in FIG. 8, the hinge assembly L can be coupled with the body 230 by the protrusion 235 at both ends. The protruding portion 235 may extend from the fixed axis SC of the hinge assembly L. [ The fixed axis SC may include a first fixed axis SC1 serving as a rotation center of the first body 210 and a second fixed axis SC2 serving as a rotation center of the second body 220. [ The first protruding portion 235a may extend from the first fixed axis SC1 and the second protruding portion 235b may extend from the second fixed axis SC2. The projecting portion 235 may be coupled to the body 230 through at least one screw.

And can be coupled to the body 230 by a link fixing portion (LF) connected from a link connecting portion (LC) located at both ends and a central portion of the hinge assembly (L). Since the hinge assembly L is engaged with the body 230 by the projecting portion 235 and the link fixing portion LF, the force when the hinge assembly L is rotated can be dispersed. Accordingly, the projecting portion 235 and the link fixing portion LF can be prevented from being damaged by force.

The first link 264 may be located at the center and both ends of the hinge assembly L, as shown in Fig. The first link 264 may be shaped to enclose the hinge assembly L. [ The first link 264 may be in the shape of a ring with an empty center. The first link 264 can be protruded on both sides. The protruding portion of the first link 264 may be coupled with the link connection and the link support.

The hinge assembly L may include at least one hole. At least one hole may engage the hinge assembly L and the body. At least one hole may be located on the first link 264. At least one hole located on the first link 264 may be fixed to the first link 264 even if the hole is changed from the first state to the second state.

A spring SP, a cam CA, and an interlocking cam ICA may be positioned inside the hinge assembly L. The spring SP may be shaped to surround the fixed axis SC. The spring SP can add elasticity so that the mobile terminal can be fixed at a certain angle.

The cam CA may be located above the spring SP. The cam CA contacts the spring SP and can move up and down by the elastic force of the spring SP. The cam CA may include a protruding portion projecting upward. The projecting portion may be a portion to be inserted into the stopper ST. That is, it means that it can be a portion inserted into a recess depressed toward the upper side of the stopper ST.

The interlocking cam ICA can be positioned on the upper side of the stopper ST. The interlocking cam ICA can guide the first fixed shaft SC1 and the second fixed shaft SC2 to move in conjunction with each other.

The cam CA and the interlocking cam ICA may be configured to simultaneously enclose the first and second fixed axes SC1 and SC2. Accordingly, the first and second fixed axes SC1 and SC2 can be interlocked with each other.

As shown in FIG. 10, in the display device according to the present invention, the spring SC and the cam CA can keep the mobile terminal in a constant state.

10 (b), the spring SP holds the first state S1 or the second state S2 in which the projected portion of the cam CA is fitted in the groove of the stopper ST So that an elastic force can be applied toward the groove.

The protrusion of the cam CA in the first state S1 is caught in one depression of the stopper ST and the length of the spring SP may be the first length SPD1. In this case, the spring SP is not compressed and the elastic force may not be applied toward the stopper ST.

On the other hand, in the third state S3 between the first state S1 and the second state S2, the projection of the cam CA deviates from the depression of the stopper ST, and the length of the spring SP May be a second length (SPD2) shorter than the first length (SPD1). In this case, the spring SP is compressed and an elastic force can be applied toward the stopper ST. Accordingly, the fixed axis SC may attempt to move to the first state S1 or the second state S2.

In the third state S1, the projecting portion of the cam CA again fits in the other depression of the stopper ST, and the length of the spring SP can be restored to the first length SPD1.

In the present invention, the protruding portion and the depression are fitted only in the portion where the first state S1 and the second state S2 are formed. However, the present invention is not limited to this, An elastic force can be applied to prevent the mobile terminal from rotating even in a state other than the state S1 and the second state S2.

As shown in Fig. 11, the interlocking cam ICA can slide up and down the fixed shaft SC in accordance with the rotation of the fixed shaft SC. The guide rail 275 can be positioned on the fixed axis SC. The guide rail 275 may be a portion where the cam ICA slides on the fixed shaft SC. The guide rail 275 may have a shape in which a groove is spirally formed on the fixed shaft SC. The guide rail 275 can engage with the projection projecting inward of the interlocking cam ICA. When the state changes from the first state to the second state, the projection of the interlocking cam ICA engages with the guide rail 275, and the interlocking cam ICA can move up and down. That is, as the fixed axis SC rotates, it means that the interlocking cam ICA can move up and down along the guide rail 275.

The guide rails 275 of the first fixed shaft SC1 and the guide rails 275 of the second fixed shaft SC may be opposite to each other in the helical direction. Accordingly, when the state changes from the first state to the second state, the first and second fixed axes SC1 and SC2 can simultaneously rotate inward.

Both the first and second fixed shafts SC1 and SC2 can be guided by the guide rails 275. Accordingly, the angle of the first fixed axis SC1 from the ground surface and the angle of the second fixed axis SC2 from the ground surface can be the same. That is, the first fixed axis SC1 and the second fixed axis SC2 can move in conjunction with each other.

The link link LC and the link supporter LS can be connected between the first link 264 and the second link 266 as shown in Fig. The first link 264 and the second link 266 may be similar to each other. The first link 264 and the second link 266 may be connected to the first hole 281 by a link connection LC and the second hole 283 by a link support LS. The second link 266 may be connected to the link fixing portion LF through the third hole 285. Since the shapes of the first and second links 264 and 266 are similar, the angle of the link connecting portion LC from the ground and the angle from the ground of the link fixing portion LF may be the same. That is, the link connecting portion LC and the link fixing portion LF are parallel.

13 to 15 illustrate operations of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 13 (a), the link connecting portion LC and the link supporting portion LS can be parallel to the y-axis direction in the first state. That is, the link connecting portion LC and the link supporting portion LS located on both sides of the hinge assembly L can be positioned in a straight line.

The distance between the link connecting portion LC and the link supporting portion LS in the first state may be the same as the distance between the first hole 281 and the second hole 283 in the z axis direction. That is, in the first state, the distance between the link connecting portion LC and the link supporting portion LS means that it can be determined by the z-direction component between the first hole 281 and the second hole 283. Accordingly, the link connecting portion LC can be positioned apart from the upper end of the link supporting portion LS.

13 (b), in the third state that is the intermediate state of the first and second states, the link connecting portion LC and the link supporting portion LS can have a certain angle with respect to the y-axis. That is, the link connecting portion LC and the link supporting portion LS can rotate toward the center portion of the hinge assembly L. [ In this case, the shapes of the first and second links 264 and 266 remain unchanged, and only the link connecting portion LC and the link supporting portion LS can be moved.

In the third state, the distance between the link connecting portion LC and the link supporting portion LS may be shorter than the distance between the first hole 281 and the second hole 283 in the z-axis direction. That is, in the third state, the distance between the link connecting portion LC and the link supporting portion LS can affect the z-direction component as well as the y-direction component between the first hole 281 and the second hole 283. The y-direction distance between the first hole 281 and the second hole 283 may be much shorter than the z-direction distance. Accordingly, the distance between the link connection portion LC and the link support portion LS can be shortened as the state changes from the first state to the second state.

As shown in FIG. 13C, in the second state, the link connecting portion LC and the link supporting portion LS may be at an angle of 90 degrees with respect to the y-axis. In this case, the shapes of the first and second links 264 and 266 remain unchanged, and the link connecting portion LC, the link supporting portion LS and the link fixing portion LF can be rotated 90 degrees inside the hinge assembly L have.

The distance between the link connecting portion LC and the link supporting portion LS in the second state may be the same as the distance between the first hole 281 and the second hole 283 in the y axis direction. That is, in the second state, the distance between the link connecting portion LC and the link supporting portion LS can be determined by the y-direction component between the first hole 281 and the second hole 283. The y-direction distance between the first hole 281 and the second hole 283 may be much shorter than the z-direction distance. Accordingly, the distance between the link connection portion LC and the link support portion LS can be shortened as the state changes from the first state to the second state. Accordingly, the link connecting portion LC can contact at least part of the link supporting portion LS. That is, when the state changes from the first state to the second state, it means that the link connecting portion LC can move toward the link supporting portion LS.

Although the figure is shown as being raised when the link fixing portion LF changes from the first state to the second state, the position of the link fixing portion LF in the body is not changed, The link connecting portion LC and the link supporting portion LS may be lowered.

When the mobile terminal according to the present invention changes from the first state to the second state, the link connecting portion LC moves toward the link supporting portion LS, and the height of the link fixing portion LF can be increased. Accordingly, the support plate SP supported by the link connection portion LC can move to the inside of the body to which the link fixing portion LF is connected. Thus, a space for storing the display D can be secured.

The fixed frame 315 and the rotary frame 319 can be connected to both sides of the hinge assembly L as shown in Fig. The hinge assembly L may be connected to one end of the fixed frame 315 and the rotary frame 319 may be connected to the other end. When the fixed frame 315 changes from the first state to the second state, the position can be fixed. That is, the fixed frame 315 does not move regardless of the rotation.

One end of the rotation frame 319 is connected to the fixed frame 315 and the other end can be inserted into the slide groove 330 located in the body. The slide groove 330 may have a shape recessed inwardly of the body. The slide groove 330 may include a locker LC at one end thereof. The locker LC may be a portion where the depressed shape is further extended downward than other portions of the slide groove 330. [ In the first state, the other end of the rotating frame 319 can be inserted into the locker LC. Accordingly, when a force exceeding a predetermined level is not applied, the rotating frame 319 may be caught in the locker LC without rotating. That is, the rotating frame 319 is fixed, which means that the display D can maintain a flat state.

When a force more than a predetermined level is applied to the body, the rotating frame 319 can slide off the locker LC and slide in the slide groove 330. In the second state, the other end of the rotary frame 319 may be positioned on the opposite side of the locker LC of the slide groove 330. In addition, a space for storing the display D may be formed on the hinge assembly L. [

As shown in FIG. 15, the slide groove 330 may be located at a portion where the fixed frame 315 and the rotating frame 319 are connected. A portion of the fixed frame 315 and the rotating frame 319 connected to each other in the first state may be caught in the locker LC of the slide groove 330. [ That is, the rotating frame 319 is fixed to the locker LC, so that the display D can maintain a flat state.

When a force more than a predetermined level is applied to the body, the rotating frame 319 can slide off the locker LC and slide in the slide groove 330.
