In order to support and enhance the functionality of such a mobile terminal, it may be considered to improve the structural and / or software aspects of the mobile terminal.

In recent years, as the thickness of the main body of the mobile terminal has become thinner and the outer appearance of the mobile terminal has become simpler, the structure protruding or recessed from the outer surface of the terminal has been minimized. Accordingly, the structure of separating the cover and the like for separating the battery is minimized, which is advantageous in that the appearance is improved, but the cover is not easy to separate.

Accordingly, it is an object of the present invention to provide a mobile terminal having a removable device for separating a cover by a control command.

According to another aspect of the present invention, there is provided a mobile terminal including a signal input unit, a cover unit covering an area of the power supply unit, And a locking protrusion which is accommodated in the terminal body so as to be movable by the translational movement of the motor unit, the detachment device detachably connecting the cover portion and the terminal main body so as to be detachable, And a control unit for controlling the translational motion of the motor unit based on a control command formed by the signal input unit to separate the cover unit from the cover unit.

As one example related to the present invention, a hole may be formed in the terminal body so that a pin for transmitting an external force can be inserted to separate the latching protrusion and the latching area. Therefore, when the control command can not be applied, the cover unit can be detached from the terminal body by applying a physical force using the pin.

In a related example of the present invention, the hole is formed adjacent to the end of the latching bar, and the hole is arranged to overlap the end surface of the latching bar, so that in a state where a control command can not be applied, The part can be separated.

In one embodiment of the present invention, the terminal body and the cover portion are composed of first and second bodies detachably coupled to each other, and the power supply portion is mounted on the second body, And the motor unit is mounted on the first body and the end of the latching bar may be arranged to engage with the latching area formed on the second body.

In one embodiment of the present invention, the detachment device further includes a latching bar including the latching area and the latching area being disposed to correspond to the latching latch,

Since the engaging protrusion is formed so as to be separated from the engaging area by the expansion of the motor part, a simple structure detachment device can be constructed without rotating and moving.

According to the present invention, the user can easily disconnect the rear cover from the rear case by applying a control command without applying an external force to the rear cover. Since the detachable device for engaging and disengaging the rear cover and the rear case is disposed inside the mobile terminal, it is not necessary to dispose an additional structure on the outer surface of the terminal body to physically separate the rear cover.

Accordingly, it is unnecessary for the user to apply an external force to the mobile terminal with a nail or the like, so that the external force of the terminal body can be minimized, and the physical structure for separation can be omitted from the outer surface of the terminal body. ?? .

The control unit 180 may control the driving or operation of the mobile terminal 100 or may perform data processing, function or operation related to the application program installed in the mobile terminal 100 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

3A and 3B are conceptual diagrams illustrating a structure of a desorption apparatus according to an embodiment of the present invention. 3C is a conceptual diagram for explaining a structure of a motor unit according to an embodiment of the present invention.

2B, 3A, and 3B, a specific structure of the detachable device 300 will be described. The detachable device 300 includes a fixing frame 331 formed on the rear cover 103, a locking bar 341 formed on the rear case 102 and a motor unit 310 for moving the locking bar 341 ). When the rear cover 103 is mounted on the rear case 102, the fixing frame 331 and the locking bar 341 are fixed. When the motor unit 310 is operated by a specific control command The fixing frame 331 and the latching bar 341 are moved by the latching bar 341 and the second elastic part 350 disposed on the latching bar 341 and the rear case 102, Separated.

The fixing frame 331 and the latching bar 341 extend in the first direction d1. The first direction (d1) may correspond to the longitudinal direction of the main body of the mobile terminal (100). The latching bar 341 is movably mounted on the rear case 102. The latching bar 341 includes at least one latching protrusion 341b protruding in a second direction d2 intersecting the first direction d1. But it is not limited thereto, and the spring 320 may be formed in a curved shape protruding in the second direction d2 and being bent in the first direction d1. When a plurality of the locking protrusions 341b are formed, the plurality of locking protrusions 341b are formed to be spaced apart from each other, and the locking protrusions 341b protrude in the same direction from each other. However, But they can protrude in different directions as long as they are parallel to each other.

The latching bar 341 includes a support protrusion 341a protruding in the second direction d2. The support protrusion 341a is engaged with the spring 320 that elastically supports the support bar 341 in the first direction d1. The rear case 102 includes a support frame 104 configured to support the support bar 341 by the spring 320.

The spring 320 is supported on one side of the support bar 341 and the motor unit 310 is disposed on the other side of the support bar 341. The motor unit 310 is fixed to one region of the support frame 102. The support frame 102 may include an accommodating portion (not shown) for accommodating the motor unit 310. The receiving portion (not shown) may be formed by an inner frame constituting an inner space of the terminal body, and may be formed adjacent to an edge region of the terminal body.

Referring to FIG. 3C, the motor unit 310 provides a force f for moving the latching bar 341 in the first direction d1. The motor unit 310 includes a nut 310a and a bolt 310a and includes a switching unit 310a and a motor 310b. The switching part 310a and the motor 310b are connected in the first direction d1. A shaft part 310c is formed at one end of the bolt part 310a. The shaft portion 310c is configured to apply a force in the first direction d1 to another component by movement. And may be made of a material capable of elastic deformation to minimize impact.

When the motor 310b is fixed to the terminal body and the bolt portion 310a is rotated, the nut portion 310a 'is rotated based on relative rotation of the bolt portion 310a and the nut portion 310a' And moves in the first direction (d1). Accordingly, the length of the motor unit 310 increases.

The inner frame constituting the inner space of the terminal main body may form a guide space for guiding the motor unit 310 to be enlarged or reduced along the first direction d1. Referring to FIG. 3A, the guide (not shown) may form a space extending from the support protrusion 341a along the first direction d1.

When the length of the motor unit 310 increases, the support bar 341 moves along the first direction d1 by the motor unit 310. [ The supporting bar 341 moved in the first direction d1 is separated from the fixed frame 331. [

The fixed frame 331 extends in the first direction d1 and is formed on the inner surface of the rear cover 103 facing the rear case 102. [ And protrudes from the inner surface of the rear cover 103, and is fixed to the latching bar 341. The fixed frame 331 includes at least one latching groove 331a. The latching groove 331a may be recessed in the second direction d2 and extend in the first direction d1. The latching groove 331a is formed to correspond to the latching protrusion 341b.

Referring to FIG. 3A, the latching bar 341 is supported by the first elastic part 320 to move in a direction opposite to the first direction d1. Thus, the latching protrusion 341b is engaged with the latching groove 331a. The movement of the latching bar 341 is limited by the first elastic portion 320 and the motor portion 310.

In this case, even if an external force is applied by the user, separation can not be performed due to the shape of the latching protrusion 341b and the latching groove 331a.

Meanwhile, when a specific control command is applied to the mobile terminal 100, the motor unit 310 is driven. The motor of the motor unit 310 rotates in one direction and the length of the motor unit 310 is increased by the conversion unit 310a. The support protrusion 341a moves while reducing the first elastic part 320 by the expansion of the motor part 310. [ By the movement of the support protrusion 341a, the latching bar 341 moves as a whole in the first direction d1.

When the latching bar 341 moves in the first direction d1, the latching protrusion 341b moves to the recessed region of the latching groove 331a in the first direction. The region recessed in the first direction is formed to be wider than the length of the bent region of the engaging projection 341b.

Referring to FIG. 2B, the latching bar 341 and the latching protrusion 341b are separated by the second elastic portion 350 disposed between the rear case 102 and the rear cover 103.

Here, the control command may correspond to an operation of the operation unit formed in the mobile terminal 100 or a touch input applied to the display unit 151, or a specific control command (operation error occurrence) . ≪ / RTI > The motor 310b rotates in one direction to extend the motor unit 310 based on the control command and when the latching bar 341 and the fixed frame 331 are separated, the motor 310b is rotated in the opposite direction Thereby reducing the motor unit 310 again.

For example, the control unit 180 of the mobile terminal 100 may be configured such that a predetermined time elapses after the motor unit 310 is extended or that the rear cover 103 and the rear case 102 are separated from each other And if it is sensed, control the motor 310b to rotate in the opposite direction.

When the length of the motor part 310 is reduced, the latching bar 341 moves in the first direction d1 by the first elastic part 320 and is restored. The locking protrusion 341b is inserted into the locking recess 331a by an external force for engaging the rear cover 103 and the rear case 102. [

The controller may be configured such that the rear case 102 and the rear cover 103 are coupled to each other so that the locking protrusion 341b is inserted into the locking recess 331a, The motor 310b can be rotated in the opposite direction to expand the motor unit 310. [

2B and 3B, the rear case 102 includes a first hole h1 formed along the one direction and passing through the inside of the mobile terminal 100 from the outside. The first hole (h1) is formed in a region overlapping the end surface of the latching bar (341).

The engaging bar 341 moves in the first direction d1 by the pin p inserted through the first hole h1. The first elastic part 320 is contracted by an external force transmitted by the pin p and the locking protrusion 341b is moved from the locking groove 331a by the elastic force of the second elastic part 350 Separated.

In this case, the length of the motor unit 310 does not change, and the motor 310b does not operate.

That is, an external force is applied through the first hole h1 to move the latching bar 341 without driving the motor unit 310 according to a control command, thereby moving the rear cover 103 and the rear case 102, Can be separated. Accordingly, when the user can not operate the motor unit 310, for example, when there is no residual power of the power supply unit, or when an error occurs in the operation of the mobile terminal 100, Can be separated.

According to the present embodiment, the user can easily disconnect the rear cover from the rear case by applying a control command without applying an external force to the rear cover. Since the detachable device for engaging and disengaging the rear cover and the rear case is disposed inside the mobile terminal, it is not necessary to dispose an additional structure on the outer surface of the terminal body to physically separate the rear cover.

Accordingly, it is unnecessary for the user to apply an external force to the mobile terminal with a nail or the like, so that the external force of the terminal body can be minimized, and the physical structure for separation can be omitted from the outer surface of the terminal body. ?? .

When the motor unit 310 is extended in the first direction d1, the locking protrusion 344a is separated from the locking groove 332 and the locking bar 344 is moved, (344a) moves along the guide surface (332 ').

When the first and second bodies 100a and 100b are coupled to each other, the length of the motor unit 310 is shortened and the locking protrusion 344a is caught in the locking recess 332. [

Since the latching bar 344 according to the present embodiment is disposed in one direction with respect to the motor unit 310, it is easy to secure the internal space.

The latching bar 345 included in the desorption apparatus according to FIG. 6C includes a latching protrusion 345a whose vertical surfaces are mutually perpendicular. Both opposing surfaces of the engaging projections 345a are parallel to each other and have an oblique surface gradually becoming narrower toward the end of the other engaging bar 345 facing each other.

The width of the latching groove 334 of the second body 100b to which the latching protrusion 345a of the latching bar 345 is caught is larger than the first thickness of the latching protrusion 345a, .

Accordingly, the motor unit 310 rotates the locking protrusion 345a by about 90 degrees so that the locking protrusion 345a is separated from or inserted into the locking recess 334. When the thin wall thickness of the locking protrusion 345a is overlapped with the locking groove 334 by the rotation of the motor unit 310, the elastic force of the spring 320 causes the locking protrusion 344a, (345a) are separated.

The fixed frame 335 is divided into first and second regions A1 and A2 having different thicknesses to form a step. The fixed frame 335 extends along the first direction d1. . The bent portion of the latching bar 342c is engaged with the first region A1 to prevent the first and second bodies 100a and 100b from being separated.

When the latching bar 342c rotates about the rotation point 342 'by the motor unit 310, the bending part is separated from the first area A1, and the first and second bodies 100a, and 100b are fixed.

Referring to FIG. 6E, the motor unit 310 of the present embodiment includes a shaft 310d having a recess 310d 'formed on one side thereof. The second body 100b includes a locking protrusion 335a protruding in one area. The locking protrusion 335a is seated in a receiving groove 335 formed in one region of the second body 100b. The locking projection 335a is elastically supported by an elastic member 335b disposed inside the receiving groove 335. [

A protruded region of the locking protrusion 335a is seated on the recess portion 310d 'in a state where one region of the locking protrusion 335a protrudes from the receiving groove 335. [

When the length of the motor unit 310 is increased according to the driving of the motor unit 310, that is, when the shaft 310d moves in the first direction d1, the locking protrusion 335a And is separated from the recessed portion 310d '. Further, the locking protrusion 335a is moved to the receiving groove 335 by one surface of the shaft 310d. Accordingly, the first and second bodies 100a and 100b are separated.

Figs. 7A and 7B are conceptual diagrams for explaining the fixing guide portions of the first and second bodies. Fig.

7A and 7B, between the first and second bodies 100a and 100b, the fixed guide portion 336 includes a guide protrusion 336a protruding from the second body 100b, And a guide groove 336b formed in the body 100a. One of the guide protrusions 336a is inserted into the guide groove 336b to prevent the first and second bodies 100a and 100b from being separated from each other.

However, the guide protrusion 336a is formed to be elastically moved into the second body 100b. Therefore, the guide protrusion 336a can be separated from the guide groove 336b by the elastic force and the tension (external force applied by the user) applied to the first and second bodies 100a and 100b.

It is possible to prevent the first and second bodies 100a and 100b from being separated instantaneously by the fixed guide portion.

The third direction d3 is a direction opposite to the first direction d1.

Referring to FIG. 3A again, when the fixing frame 331 moves in the third direction d3, the locking protrusion 341b is separated from the locking groove 331a by the elastic force of the spring 320. FIG. The detachment apparatus according to the present embodiment may further include a roller unit 520 for guiding the movement of the fixed frame 331.

According to the present embodiment, when the movement of the fixed frame 331 can not be controlled based on the control command applied to the mobile terminal 100, the manipulator 510 can be used to separate it by external force.

9A and 9B are conceptual diagrams for explaining a control method of a mobile terminal for opening and closing a cover portion according to different embodiments of the present invention.

Referring to FIG. 9A, the controller 180 activates the battery separating function based on a specific control command (S11).
