TECHNICAL FIELD

The present invention relates to a mobile device.

BACKGROUND ART

A terminal may be classified into a mobile device (mobile/portable terminal) and a fixed terminal (stationary terminal) according to whether it may move. Further, the mobile device may be classified into a portable terminal (handheld terminal) and a holdable terminal (vehicle mounted terminal).

Functions of the mobile device are being diversified. For example, the functions include data and voice communication, picture shooting and video shooting through a camera, voice recording, reproduction of a music file through a speaker system and outputting of an image or a video to a display unit. Some terminals have an electronic game playing function added thereto or perform a multimedia player function. In particular, recent mobile devices may receive multi-cast signals that provide visual contents such as broadcasting, video and a television program.

Such a terminal has the diversified functions, and thus is implemented in a form of a multimedia player having complex functions including, for example, shooting of a picture or a video, reproduction of a music file or a video file, a game, reception of broadcasting or the like.

Further, as the mobile device is considered as a personal portable item for representing personality of a user, various design forms thereof are required. The design forms include structural changes and modifications for allowing the user to more easily use the mobile device.

Modifying a structural portion of the terminal may be considered to support and increase the functions of the terminal.

In a mobile device according to the related art, a body in which electronic elements such as a display unit that outputs an image, a printed circuit board and a battery are provided is a single case, and thus, a design change of the mobile device is restrained. Further, because various configurations should be arranged inside the single case, it is difficult to design an inner structure of the mobile device.

FIG. 1is a front perspective view illustrating a mobile device according to an embodiment of the present invention, andFIG. 2is an exploded perspective view illustrating the mobile device according to the embodiment of the present invention.

Referring toFIGS. 1 and 2, a mobile device1according to the embodiment of the present invention includes a first body100through which an image is output, a second body200arranged in parallel to the first body100and having an electronic element for transferring electric power and a control instruction to the first body100, and a connection member300electrically connecting the first body100and the second body100to each other.

The first body100includes a case110(for example, a frame, a housing, a cover and the like) defining an outer appearance. As illustrated, the case110may include a first front case111and a first rear case113. Various kinds of electronic elements are arranged inside an inner space formed by coupling between the first front case111and the first rear case113. At least one middle case may be additionally arranged between the first front case111and the first rear case113.

Such a case110may be formed by injecting synthetic resin or may be formed of metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti) and the like.

The first body100has a bar-shaped terminal body. A display unit101is arranged on a front surface of the first body100to output information. As illustrated, a window101aof the display unit101is mounted on the first front case111to define the front surface of the first body100together with the first front case111.

Dissimilar to the above example where the inner space accommodating various kinds of electronic elements is defined by a plurality of cases, the first body100may be formed such that the inner space is defined by one case. In this case, the first body100formed of synthetic resin or metal and corresponding to a unibody extending from a side surface to a rear surface may be implemented.

Meanwhile, the mobile device100may include a waterproof part (not illustrated) preventing water from being permeated into the terminal body. For example, the waterproof part may include waterproof members provided between the window101aand the first front case111and between the first front case111and the first rear case113to seal the inner space when they are coupled to each other.

The display unit101displays (outputs) information processed by the second body100. For example, the display unit101may display information on an execution screen of an application program driven by the mobile device1or information on a user interface (UI) and a graphic user interface (GUI) according to the information on the execution screen.

The display unit101may include at least one of a liquid crystal display (LCD), a thin-film transistor-liquid crystal display (TFT LCD), an organic light emitting diode (OLED), a flexible display, a three-dimensional display and an electronic-ink display.

The display unit101may include a touch sensor detecting a touch on the display unit101to receive input of a control instruction through a touch scheme. Using the same, when a touch is made on the display unit101, the touch sensor detects the touch, and a control unit (not illustrated) generates a control instruction corresponding to the touch based on the same. The contents input through the touch scheme are a letter or a number, or a menu item that may be indicated or designated in various modes.

Meanwhile, the touch sensor is formed in a film form having a touch pattern to be arranged between the window101aand a display (not illustrated) on a rear surface of the window101aor may be a metal wire directly patterned on the rear surface of the window101a. Further, the touch sensor may be formed integrally with the display. For example, the touch sensor may be arranged on a substrate of the display or may be provided inside the display.

In this way, the display unit101may have a touch screen together with the touch sensor, in which case the touch screen may function as a user input unit.

The second body200is arranged in parallel to the first body100to be spaced apart from the first body100by a predetermined interval. Thus, the size and the shape of the second body200may be the same as those of the first body100.

The second body200includes a case210(for example, a frame, a housing, a cover and the like) defining an outer appearance. As illustrated, the case210may include a second front case211and a second rear case213. Various kinds of electronic elements are arranged inside an inner space formed by coupling between the second front case211and the second rear case213. At least one middle case may be additionally arranged between the second front case211and the second rear case213.

When a surface of the second body200, which faces the first body100, is assumed as a front surface and an opposite surface thereto is assumed as a rear surface, an auxiliary display unit220through which an image is output may be provided on the front surface of the second body200.

Like the display unit101, the auxiliary display unit220may include at least one of a liquid crystal display (LCD), a thin-film transistor-liquid crystal display (TFT LCD), an organic light emitting diode (OLED), a flexible display, a three-dimensional display and an electronic-ink display. Further, the auxiliary display unit220may also include a touch sensor detecting a touch on the display unit220to receive input of a control instruction through a touch scheme.

Thus, the auxiliary display unit220may perform a control such that the same screen as the image output on the display unit101or a different image therefrom is output.

A first camera240may be mounted on one side edge of the auxiliary display unit220. A first detection sensor242is provided on one side of a left edge and a right edge of the second body200and a second detection sensor244is provided on the other side of the left edge and the right edge of the second body.

The leftward or rightward movements of the first body100and the second body200are detected by the first detection sensor242and the second detection sensor244, and descriptions thereof will be made below. Further, a distance between the mobile device1and a subject is detected by a detection sensor, which is closer to the first camera240, among the first detection sensor242and the second detection sensor244.

The first camera121aprocesses an image frame of a still image or a moving image obtained by an image sensor in a shooting mode or a video call mode. The processed image frame may be displayed on the display unit101or the auxiliary display unit220and may be stored in a memory.

The connection member300is coupled to the first body100and the second body200at lower ends of the first body100and the second body200, respectively, to mutually electrically connect the first body100and the second body200to each other.

As illustrated in the drawings, the connection member300includes a body310defining an outer appearance, a first installation part301and a second installation part303provided on an upper surface of the body310, on which the first body100and the second body200are positioned, respectively.

The body310has a semicircular side surface having a groove formed at a center thereof.

A material of the boy310may be a flexible material. Thus, when an external force is applied to the body310, the body310is deformed, so that various angles may be formed such that the first body100and the second body200may move in a direction in which they cross each other or in a direction in which they are parallel to each other.

Further, a material of the boy310may be a rigid material not deformed by the external force. In this case, the connection member300is coupled to the first body100and the second body300to fix the first body101and the second body200to each other.

Hereinafter, for convenience of description, an example where the material of the body310is manufactured of a flexible material will be described.

Meanwhile, catching protrusions301and302to be coupled to the first body100and the second body200and terminals322and324to be electrically connected to the first body100and the second body200are formed in the first installation part301and the second installation part303, respectively. A coupling structure of the connection member300and the bodies100and200will be described below.

FIG. 3is a sectional view illustrating a rear surface of the second body according to the embodiment of the present invention.

Referring toFIG. 3, a second camera270may be arranged on a rear surface of the second body200. In this case, the second camera270has a shooting direction that is substantially opposite to the first camera240.

Further, a rear input unit230may be provided on a rear surface of the second body200as an example of the user input unit. The rear input unit230is manipulated to receive input of an instruction for controlling an operation of the mobile device1, and input contents may be variously set. For example, the rear input unit230may receive input of instructions such as an ON/OFF operation of a power source, start, termination, and scrolling and instructions such as adjusting of the size of sounds output by a voice outputting unit and switching of the display unit101into a touch recognition mode. The rear input unit230may be implemented in which a touch input, a push input and an input by a combination thereof may be performed.

In detail, the rear input unit230includes a first button part232exposed from the rear surface of the second body200to the outside to receive a push input having a first function and a second button part234having keys arranged on opposite sides of the first button part232to receive a push input having a second function that is different from the first function. The second button part234has a through-hole at a center thereof so that the first button part232is arranged at a center of the second button part234.

As an example of a user input, the first function may be a function related to the ON/OFF operation of the power source and activation of the display unit101, and the second function may be a function related to scrolling of output information of the display unit or adjusting of the volume of sounds output by the mobile device1.

The rear input unit230may be arranged to overlap the auxiliary display unit201on a front surface thereof in a thickness direction of the terminal body. As an example, the rear input unit230may be arranged at a rear upper end of the second body200such that the user may easily manipulate the terminal body using an index finger when holding the terminal body by one hand. However, the present invention is not necessarily limited thereto, and a location of the rear input unit230may be changed.

In this way, when the rear input unit230is provided on the rear surface of the second body200, a new type of user interface may be implemented using the same. Further, the display unit151may be a larger screen due to the above-described touch screen or the rear input unit230.

FIG. 4is a perspective view illustrating a state in which the first body is relatively moved with respect to the second body according to the embodiment of the present invention, andFIG. 5is a side sectional view illustrating the mobile device in a state in which a button part is manipulated according to the embodiment of the present invention.

Referring toFIG. 4, because the body310of the connection member300is manufactured of a flexible material, the first body100may be relatively moved with respect to the second body200. It is apparent that the second body200may be relatively moved with respect to the first body100. Further, although a state in which the first body100is moved in a vertical direction that is a direction in which it goes farther away from the second body200is illustrated in the present drawing, the first body100may be moved to left and right sides of the ‘second body200.

When a surface of the first body100, on which the display unit101is formed, is assumed as a front surface and an opposite surface thereto is assumed as a rear surface, a button part120as another example of the user input unit may be provided on the rear surface of the first body100.

The button part120is manipulated to receive input of an instruction for controlling an operation of the mobile device1, and input contents may be variously set. For example, referring toFIG. 5, when an image frame processed by the second camera270in a camera shooting mode is displayed on the display unit101, the user pushes the front surface of the first body100and the rear surface of the second body200such that the rear surface of the first body100comes into contact with the front surface of the second body200.

Because of this, since the button part120is pushed on the front surface of the second body200, a camera shooting instruction is transferred to the second camera270to perform shooting.

Further, functions related to the ON/OFF operation of the power source or the activation of the display unit101may be performed through the pushing of the button part120.

Hereinafter, a structure of the connection member300will be described.

FIG. 6is a perspective view illustrating the connection member according to the embodiment of the present invention, andFIG. 7is an exploded perspective view illustrating the connection member according to the embodiment of the present invention.

Referring toFIGS. 6 and 7, as described above, the first installation part301on which the first body100is positioned and the second installation part303on which the second body is positioned are provided on the upper surface of the body310while a groove311formed in the body310is interposed therebetween.

In detail, the first installation part301includes a first installation surface301aon which a bottom surface of the first body100is positioned, and the second installation part303includes a second installation surface303aon which a bottom surface of the second body200is positioned.

Further, first catching protrusions302to be inserted into coupling grooves formed in the first body100are formed at opposite side edges of the first installation surface301a, respectively, and second catching protrusions304to be inserted into coupling grooves formed in the second body200are formed at opposite side edges of the second installation surface303a, respectively.

Meanwhile, the body310includes a first frame311defining an outer appearance and a second frame312fitted in the first frame311.

The first frame311has the groove311inward formed on a semicircular cross-section thereof. Further, the second frame312is coupled to an inside of the first frame311in which the groove311is formed. That is, an outer peripheral surface312aof the second frame312comes into contact with an inner peripheral surface of the groove311so that the first frame311and the second frame312are coupled to each other.

A connection part320is provided between the first frame311and the second frame312. The connection part320is coupled to the first body100and the second body200to electrically connect the first body100and the second body200to each other.

The connection part320includes a flexible substrate321that is deformable by an external force, a first terminal322formed at one end of the flexible substrate321and inserted into the first body100, and a second terminal324formed at the other end of the flexible substrate321and inserted into the second body200.

Further, through-holes are formed in the first installation part301and the second installation part303such that the first terminal322and the second terminal324pass therethrough, respectively. Thus, as illustrated, when the first installation part301and the second installation part303are coupled to the upper surface of the body310, the first terminal322and the second terminal324protrude upward from the installation surfaces301aand303a, respectively.

FIG. 8is a sectional view illustrating a state in which the first body and the second body are coupled to the connection member according to the embodiment of the present invention.

Referring toFIG. 8, coupling grooves103and203extending toward insides of the first body100and the second body200are formed on the bottom surfaces of the first body100and the second body200, respectively. The coupling grooves103and203are formed at opposite ends of the bottom surfaces of the first body100and the second body200to correspond to the catching protrusions302and304formed on the installation surfaces301aand303aof the connection member300, respectively.

Further, first protrusions303extending toward insides of the coupling grooves103are formed at ends of the first catching protrusions302, respectively, and second protrusions305extending toward insides of the coupling grooves203are formed also at ends of the second catching protrusions304, respectively.

As illustrated, when the catching protrusions302and304are inserted into the coupling grooves103and203, respectively, the first protrusions303are caught by the first front case111of the first body100, and the second protrusions305is caught by the second rear case213of the second body200. Thus, the first body100and the second body200may be mutually electrically connected to each other through the connection member300.

Meanwhile, although not illustrated, the first body100and the second body200may be coupled to the connection member300by a magnetic force. In this case, as metals are attached to the bottom surfaces of the first body100and the second body100or the installation surfaces301aand303aand magnets are coupled to the others thereof, the first body100and the second body200may be coupled to the connection member300.

FIG. 9is a perspective view illustrating a state in which the first body is decomposed according to the embodiment of the present invention.

Referring toFIG. 9, the first body100includes a case110defining an outer appearance, a window101adefining a front surface of the case110, a display unit101outputting an image on a rear surface of the window101a, and an auxiliary battery140and an auxiliary substrate part130arranged inside the case110.

As described above, the case110is formed by coupling the first front case111and the first rear case113to each other, and the display unit101, the auxiliary battery140, and the auxiliary substrate part130are arranged in an inner space defined by coupling the first front case111and the first rear case113.

An exposure hole113is formed on a front surface of the first front case111such that the display unit101is exposed to the outside through the window101a. Further, the window101ais inserted into edges of the exposure hole113on the front surface of the first front case111.

The auxiliary substrate part130is arranged on a rear surface of the display unit101, and electronic elements for driving the first body110are mounted thereon. A groove132on which the auxiliary battery140is seated is formed on one side of the auxiliary substrate part130, and the auxiliary battery140is provided along a circumference of the groove132to supply electric power required by the first body110.

In this way, as the auxiliary battery140and the auxiliary substrate part130are provided even in the first body100, the first body100may be independently driven even when the first body100and the second body200are separated from each other. Meanwhile, it is apparent that the mobile device1may be designed such that the auxiliary battery140and the auxiliary substrate part130are not auxiliary conceptual configurations of a main battery250and a main substrate part260arranged in the second body200, which will be described below.

The first rear case113covers the rear surface of the first body100. The hole113is formed on the first rear case113such that a pressure of the button part120is transferred, and a push pressure of the button part120is transferred to the auxiliary substrate part130through the hole113.

An exposure hole212is formed on a front surface of the second front case211such that the auxiliary display unit220is exposed to the outside through the window220a. Further, the window220ais inserted into edges of the exposure hole212on the front surface of the second front case211. The auxiliary display unit220is formed to have a size that is relatively smaller than that of the display unit101so as to assist a displayed screen of the display unit101or display another screen. In contrast, it is apparent that the auxiliary display unit220is also formed to correspond to the size of the display unit101.

The main substrate part260is arranged on a rear surface of the display unit220, and electronic elements for driving the first body100and the second body200are mounted thereon. A groove262on which the main battery250is seated is formed on one side of the main substrate part260, and the main battery250is provided along a circumference of the groove262to supply electric power required for driving the mobile device100.

The second rear case213covers the rear surface of the second body200. The rear input unit230and holes214and271through which the second camera270is exposed to the outside are formed on the second rear case213. Thus, the second camera270mounted on the main substrate part260is exposed to the outside, and a push pressure of the rear input unit230is also transferred to the main substrate part260.

The auxiliary module400is formed to correspond to the sizes and the shapes of the first mounting part100and the second mounting part200and is mounted on a space S defined by the first mounting part100and the second mounting part200.

The auxiliary module400may have various functions. As an example, the auxiliary module400may function as a large capacity battery to supply electric power required for driving the mobile device1. In this case, the auxiliary module400may supply electric power while being driven together with the main battery250and the auxiliary battery140and may serve as a battery pack used when the capacities of the main battery250and the auxiliary battery140are exhausted.

As another example, the auxiliary module400may serve as a speaker outputting stereoscopic sounds. In this case, the auxiliary module400may be implemented in a form of a loud speaker outputting various alarm sounds or reproduction sounds of multi-medias. Thus, the auxiliary module400may output the stereoscopic sounds together with speakers installed in the first body100and the second body200to satisfy a hearing sense of the user.

Referring toFIG. 12, the auxiliary module400may be formed to have an approximately plate shape corresponding to the sizes of the first body100and the second body200. An insertion groove410is formed on one surface of the auxiliary module400. The button part120formed on a rear surface of the first body100is inserted into the insertion groove410. Thus, when the auxiliary module400is mounted in the space S, the first body100and the auxiliary module400are not spaced apart from each other by the button part120.

Further, connection terminals420are formed above the button part120to be electrically connected to the first body100. Thus, the connection terminals420will be described below.

Referring toFIG. 13, the auxiliary module400may be coupled to the first body100and the second body200by a magnetic force. In detail, a first metal part180is formed inside the first body100to be adjacent to the rear surface of the first body100, and a second metal part280is formed inside the second body200to be adjacent to the front surface of the second body200. Further, a magnet part430may be provided inside the auxiliary module400to be parallel to a vertical direction in which the first and second metal parts180and280face each other.

That is, the auxiliary module400is a magnetic member having a magnet provided therein, and the first and second metal parts180and280which are magnetic bodies are mounted on the insides of the first body100and the second body200, so that the first body100and the second body200are maintained to be in close contact with the auxiliary module400by an interaction between the magnetic member and the magnetic bodies.

Thus, when the auxiliary module400is mounted in the space S, a magnetic force is generated between the magnetic part430and the first and second metal parts180and280, so that the auxiliary module400is fixed to the space S.

A protrusion is formed at an upper end of the auxiliary module400so that the auxiliary module400may be fixed through a catching structure at upper ends of the first body100and the second body200.

Referring toFIG. 14, the first body100may further include clips290to be electrically connected to the auxiliary module400. Further, holes291through which the clips290are exposed to the outside may be formed on the rear surface of the first body100. The holes291are formed to face the connection terminals420provided in the auxiliary module400, respectively, when the auxiliary module400is mounted in the space S.

The clips290extend from one side of the auxiliary substrate part130arranged inside the first body100to be exposed to the outside of the first body100through the holes291. Thus, the auxiliary module400is mounted in the space S and the clips290come into contact with the connection terminals420provided in the auxiliary module400, so that the auxiliary module400and the first body100are electrically connected to each other.

Meanwhile, although an example where the clips290extend from the inside of the first body100toward the outside of the first body and the connection terminals420are arranged on a surface of the auxiliary module400, which faces the first body100, is described in the present embodiment, it is probable that the clips290extend from the inside of the second body200toward the outside of the second body200and the connection terminals420are arranged on a surface of the auxiliary module400, which faces the second body100, so that an electric connection is achieved.

Thus, when the auxiliary module400functions as a battery pack, the auxiliary module400may supply electric power to the first body100and the second body200, and when the auxiliary module400functions as a speaker, the auxiliary module400may output sounds according to a control instruction.

Hereinafter, a shooting process for the mobile device1will be described.

FIG. 15is a flowchart illustrating the shooting process of the mobile device according to the embodiment of the present invention,FIG. 16is a view illustrating a home screen displayed on the mobile device according to the embodiment of the present invention, andFIG. 17is a view illustrating a shooting screen displayed on the mobile device according to the embodiment of the present invention.

Referring toFIGS. 15 to 17, first, the user activates the home screen on the display unit101(S100). As an example, the home screen can be activated on display unit101by pushing the rear input unit230provided on the rear surface of the second body200. Thus, as illustrated inFIG. 16, the home screen is displayed on the display unit101.

In a state in which the home screen is output on the display unit101, the user moves the first body100relatively to a left side of the second body200(S200). Thus, the first camera240and the first detection sensor242provided on the front surface of the second body200have been covered by the first body100and are exposed to the outside as the first body100is moved to a left side. The control unit detects that the first camera240and the first detection sensor242are exposed, and displays a shooting screen on the display unit101, as illustrated inFIG. 17(S300).

When the shooting mode is output to the display unit101, an image frame of a subject is output to the display unit101by the first camera240. Here, the first detection sensor242measures a distance from the subject to adjust a focus of the first camera240.

When recognizing the image frame output to the display unit101and wanting shooting, the user pushes the rear input unit230(S400). Shooting is performed as the rear input unit230is pushed (S500), and the processed image frame may be displayed on the display unit101or the auxiliary display unit202and may be stored in the memory.

Further, the user performs shooting by directly touching a shooting button (B) provided on the shooting screen, on the shooting screen output to the display unit101. In this case, the shooting is performed only using the shooting button (B) without pushing the rear input unit230.

Thus, there is an advantage in that the user may enter the shooting mode using a simple operation in which the first body100and the second body200are moved.

FIG. 18is a view illustrating a home screen displayed on the mobile device according to the embodiment of the present invention,FIG. 19is a view illustrating a home screen when the first body is moved to a left side according to the embodiment of the present invention, andFIG. 20is a view illustrating a home screen when the first body is moved to a right side according to the embodiment of the present invention.

Referring toFIGS. 18 to 20, in the mobile device1, as the first body100is moved to left and right sides of the second body200, a selected icon may be changed.

When the first body100is moved to a left side of the second body200, the first detection sensor242formed on the front surface of the second body200is exposed to the outside, and thus the control unit detects that the first body100is moved to the left side, by recognizing this fact.

Further, when the first body100is moved to a right side of the second body200, the second detection sensor244formed on the front surface of the second body200is exposed to the outside, and thus the control unit detects that the first body100is moved to the right side, by recognizing this fact.

As an example, when any one of icons of the home screen is selected as illustrated inFIG. 18and the first body100is moved relatively to the left side of the second body200as illustrated inFIG. 19, the selected icon is changed to a left icon.

Further, when the first body100is moved relatively to a right side of the second body200as illustrated inFIG. 20, the selected icon is changed to a right icon.

Thus, the user may simply and conveniently manipulate the screen through movements of the first body100and the second body200in addition to the touch.

The selected icon may be activated by pushing the button part120.

FIG. 21is a view illustrating a map screen displayed on the mobile device according to the embodiment of the present invention,FIG. 22is an enlarged view illustrating the map screen displayed on the mobile device according to the embodiment of the present invention, andFIG. 23is a reduced view illustrating the map screen displayed on the mobile device according to the embodiment of the present invention.

Referring toFIGS. 21 to 23, in the mobile device1, as the first body100is moved to left and right sides of the second body200, the screen may be enlarged or reduced.

When the first body100is moved to a left side of the second body200, the first detection sensor242formed on the front surface of the second body200is exposed to the outside, and thus the control unit detects that the first body100is moved to the left side, by recognizing this fact.

Further, when the first body100is moved to a right side of the second body200, the second detection sensor244formed on the front surface of the second body200is exposed to the outside, and thus the control unit detects that the first body100is moved to the right side, by recognizing this fact.

As an example, as illustrated inFIG. 21, the map screen is output to the display unit101, the user moves the first body100to the left side of the second body200. The control unit detects that the first detection sensor242is exposed to the outside, and the map screen is enlarged as illustrated inFIG. 22. Here, a degree to which the map is enlarged is adjusted through a duration time for which a state in which the first body100is moved to a left side is maintained.

When the user moves the first body100to a right side of the second body200, the control unit detects that the second detection sensor244is exposed to the outside, and the map screen is reduced as illustrated inFIG. 23. The degree to which the map is reduced is adjusted through a duration time for which a state in which the first body100is moved to a right side is maintained.
