Description

  The present invention relates to a mobile terminal. In particular, the present invention relates to a mobile terminal in which a display casing of a mobile terminal having a display casing and a key operation casing is overlapped by rotating about 180 degrees with respect to the key operation casing.

2. Description of the Related Art There is known a portable terminal that has a display casing and a key operation casing and in which the display casing is reversed and overlapped with the key operation casing. For example, Patent Document 1 discloses a mobile communication device provided with a display casing having a display section, an operation casing having an operation section, and a hinge section that connects the display casing and the operation casing in an openable and closable manner. In the portable communication device, an opening / closing axis X and a rotation axis orthogonal to the opening / closing axis X are provided in the hinge portion, and the display portion of the display housing is supported so as to be turned upside down around the rotation axis.
JP 2007-110589 A

  However, the portable communication device disclosed in Patent Document 1 includes a hinge portion having an opening / closing axis and a rotation axis that are orthogonal to each other for the purpose of inverting the display portion of the display housing around the rotation axis. Such a hinge part has a complicated structure and may increase the manufacturing cost. Further, the complicated structure of the hinge part may cause a decrease in product reliability. Furthermore, such a structure of the hinge portion has a large space occupation volume, and there are many problems as a structure to be adopted for a portable terminal that is desired to be downsized or thinned.

  In order to solve the above-described problems, in the first embodiment of the present invention, a lower housing, an upper housing that can be held by being overlapped with the lower housing, and the upper housing with respect to the lower housing. A holding unit that holds the upper case so as to be rotatable by 180 degrees, a lower operation unit provided on an upper case facing surface that faces the upper case of the lower case, and a lower case according to the rotation of the upper case with respect to the lower case The main display unit provided on the display surface that is one of the two opposing surfaces of the upper casing that faces the upper casing, and the upper portion provided on the operation surface that is the other opposing surface of the two opposing surfaces And an operation unit.

  The above summary of the invention does not enumerate all the necessary features of the present invention, and sub-combinations of these feature groups can also be the invention.

  Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the scope of claims, and all combinations of features described in the embodiments are included. It is not necessarily essential for the solution of the invention.

  In the following description, when the term “upper” or “lower” is used, a member located at the upper part in an assumed operation state is indicated as “upper”, and a member located at the lower part is indicated as “lower”. However, depending on how the mobile terminal 10 is used, the top and bottom of the member may be reversed, and the positional relationship between the “upper” and “lower” members may not match the name. That is, the term “upper” or “lower” in this specification is merely an index and does not mean an actual positional relationship.

  In addition, when the term “abbreviation” is used in the following description, a range that can be identified in the technical sense is used as the meaning of “abbreviation”. For example, in the case of “approximately 180 degrees”, there may be a case where it actually deviates from 180 degrees due to a manufacturing error of the member shape or a margin of a member position assumed at the time of design. Such a deviation range is included in the “substantially” range. In addition, even if the designer deliberately designs with a deviation from 180 degrees, technically meaningless deviation is intended by the designer, such as when the deviation does not produce a significant technical effect. Regardless of whether or not, it is included in the “substantially” range.

  FIG. 1 shows an appearance of the portable terminal 10 according to the present embodiment in one state. The mobile terminal 10 includes an upper housing 100 and a lower housing 200. In the drawing, the mobile phone 10 is shown in a state where the upper housing 100 is overlapped with the lower housing 200 and the upper housing 100 is closed with respect to the lower housing 200. The mobile terminal 10 can be used as, for example, a mobile phone in the state shown in FIG. Hereinafter, this state is referred to as “position 1”.

  FIG. 2 shows an appearance of the mobile terminal 10 in another state. In the figure, the mobile terminal 10 in a state where the upper casing 100 is opened with respect to the lower casing 200 is shown. The portable terminal 10 can be used as, for example, a portable information terminal in the state shown in the figure. Hereinafter, this state is referred to as “position 2”.

  FIG. 3 shows an appearance of the mobile terminal 10 in yet another state. In the drawing, the mobile phone 10 is shown in a state where the upper housing 100 is overlapped with the lower housing 200 and the upper housing 100 is closed with respect to the lower housing 200. However, the state in position 1 is different from the state in which the upper housing 100 is rotated 180 degrees with respect to the lower housing 200. In the state shown in the figure, the portable terminal 10 can be used as, for example, a camera, a television, a portable game machine, or a portable book terminal. Hereinafter, this state is referred to as “position 3”.

  FIG. 4 shows an appearance of the back surface of the mobile terminal 10 in the position 1 or 3. The mobile terminal 10 of the present embodiment includes an upper casing 100, a lower casing 200, a hinge 300, a lower rotating shaft 410, and an upper rotating shaft 420. The upper housing 100 includes a sub display unit 110, an upper operation unit 120, a main display unit 130, an auxiliary operation unit 140, a groove 150, a notch 160, a speaker 190, and a microphone 195. The lower housing 200 includes a protruding portion 210, a hinge support portion 220, a lower operation portion 230, an imaging optical system 240, a battery pack 250, a composite switch 260, and a slide switch 265.

  The upper housing 100 and the lower housing 200 have a rectangular shape having substantially the same size. The upper housing 100 is held so as to be able to rotate about 180 degrees with respect to the lower housing 200 and can be held by being overlapped with the lower housing 200. A mechanism in which the upper casing 100 is held so as to be rotatable by 180 degrees with respect to the lower casing 200 can be realized as follows.

  Two hinge support portions 220 that support the hinge 300 are provided at both ends of the long side of the lower housing 200. One end of each of the two hinges 300 is rotatably supported by the two hinge support portions 220. Then, the two side surfaces of the upper housing 100 are rotatably supported on the other ends of the two hinges 300. The rotatable support can be realized, for example, by arranging a rotation shaft at the rotation center.

  That is, by allowing the lower rotation shaft 410 to pass through the hole opened in the hinge support part 220 and the hole opened in the hinge 300, the hinge 300 is held rotatably with respect to the hinge support part 220. Further, the upper rotary shaft 420 is rotatably held with respect to the hinge 300 by passing the upper rotary shaft 420 through the hole opened in the hinge 300 and the hole opened in the side surface of the upper housing 100. Here, the axial direction of the lower rotating shaft 410 and the upper rotating shaft 420 is substantially parallel, and is also substantially parallel to the long side direction of the upper casing 100 or the lower casing 200. The lower rotating shaft 410 and the upper rotating shaft 420 may be formed integrally with the hinge 300.

  With the above mechanism, the upper casing 100 is held so as to be rotatable about 180 degrees with respect to the lower casing 200, and can be held while being superimposed on the lower casing 200. According to the above mechanism, the upper casing 100 can be reversed and overlapped with the lower casing 200 without using a hinge by two rotation axes orthogonal to each other, that is, a so-called swivel rotating hinge. As a result, the structure can be simplified and the manufacturing cost can be reduced. In addition, the reliability of the product can be increased. Furthermore, since the structure is simplified, the occupied space volume can be reduced and the product can be made smaller or thinner.

  The upper housing 100 and the lower housing 200 have a rectangular shape as described above. In the following description, the surfaces of the upper housing 100 and the lower housing 200 are defined for convenience. A main display unit 130 is disposed on one surface of the upper housing 100, and an upper operation unit 120 is disposed on the other surface of the upper housing 100. Therefore, one surface of the upper housing 100 in which the main display unit 130 is disposed is denoted as “display surface”, and the other surface of the upper housing 100 in which the upper operation unit 120 is disposed is denoted as “operation surface”.

  However, it does not mean that all members arranged on the “display surface” have a display function, or that all members arranged on the “operation surface” have an operation function. Further, the surface of the lower housing 200 facing the upper housing 100 is referred to as an “upper housing facing surface”, and the opposite surface is referred to as an “upper housing non-facing surface”.

  The upper housing 100 and the lower housing 200 are made of, for example, high-performance engineering plastic, and electronic circuits are mainly arranged inside. The electronic circuit disposed inside is, for example, a drive circuit of a liquid crystal display device that is an example of the main display unit 130 or the sub display unit 110, a numeric keypad that is an example of the upper operation unit 120, or an operation button that is an example of the auxiliary operation unit 140. It may be a control circuit or the like. Further, it may be a control circuit for controlling the mobile terminal 10 or the like.

  The hinge 300 holds the upper casing 100 so as to be rotatable about 180 degrees with respect to the lower casing 200 by the mechanism described above. The hinge 300 is an example of a holding unit. In addition, the hinge 300 is rotated about the lower rotation axis 410, the first position where the angle between the upper housing facing surface and the long side of the hinge 300 is approximately 0 degrees, the second position where the angle is approximately 90 degrees, or The angle is fixed at the third position exceeding 90 degrees. The angle of the third position can be exemplified by 135 degrees or 160 degrees, for example.

  Examples of the mechanism for fixing the hinge 300 to the angle include the following mechanisms. For example, the lower rotating shaft 410 is fixed to the lower casing 200 and small protrusions are formed on the lower rotating shaft 410. On the other hand, a small groove is formed in a hole through which the lower rotating shaft 410 of the hinge 300 passes. The small protrusion and the small groove are engaged with each other, and the hinge 300 is fixed when the small protrusion is engaged. In addition, any mechanism that can control the movement and fixing of the hinge 300 such as providing a clutch in the sliding portion of the lower rotating shaft 410 can be adopted.

  A sub display unit 110, an upper operation unit 120, a speaker 190, and a microphone 195 are provided on the operation surface of the upper housing 100. A groove 150 is formed on the operation surface of the upper housing 100. On the display surface of the upper housing 100, a main display unit 130 and an auxiliary operation unit 140 are provided. Further, a cutout 160 is formed in the upper housing 100.

  The sub display unit 110 is responsible for display at the position 1 and presents information such as time, a call waiting screen, and operation status. The display content of the sub display unit 110 changes according to the operation of the upper operation unit 120. For example, when a number key is pressed, the number is changed. The upper operation unit 120 is responsible for operations at position 1, and can be exemplified by a numeric keypad, for example.

  The main display unit 130 is responsible for display at position 2. The main display unit 130 has a larger display area than the sub display unit 110, and is suitable for an application that requires a large screen display, such as when playing a game or watching a television or video. Further, the display content of the main display unit changes according to the operation of the lower operation unit 230 or the auxiliary operation unit 140. For example, when a character key which is the lower operation unit 230 is pressed, the character is displayed or the like is changed. Alternatively, in the game operation, the game display is changed, for example, an arrow key that is the auxiliary operation unit 140 is pressed to instruct the progress of the game.

  The auxiliary operation unit 140 performs an operation at position 2 or position 3. An example of the auxiliary operation unit 140 is an arrow key. The keys of the auxiliary operation unit 140 are suitable for, for example, game operations or page turning key operations in an electronic book terminal.

  The groove 150 is formed in the vicinity of the short side of the upper housing 100 and fits the hinge 300 in the position 1 or position 3 state. Further, the depth of the groove 150 is deeper than the thickness of the hinge 300. Since the groove 150 is formed, the upper surface of the hinge 300 does not protrude with respect to the operation surface of the upper casing 100 and does not hinder the operation. It can also provide a clean design.

  The notches 160 are formed at the four corners of the upper housing 100. In the state of position 1 or position 3, the hinge support part 220 and the protrusion part 210 of the lower housing 200 are fitted. Since the hinge support portion 220 protrudes from the upper housing facing surface of the lower housing 200, the upper housing 100 can be brought into close contact with the lower housing 200 due to the notch 160. The notch 160 corresponding to the protrusion 210 corresponds to the hinge support 220 when the upper housing 100 is inverted.

  The speaker 190 generates a reception sound when the mobile terminal 10 is used as a telephone, for example. The microphone 195 collects sound when the mobile terminal 10 is used as a telephone, for example.

  The lower casing 200 has a protrusion 210, a hinge support section 220, and a lower operation section 230 on the upper casing facing surface. The lower casing 200 has an imaging optical system 240 and a battery pack 250 on the non-facing surface of the upper casing. A composite switch 260 and a slide switch 265 are provided on the side surface of the lower housing 200.

  The protrusion 210 fits into the notch 160 of the upper housing 100. Due to the presence of the protrusion 210, the presence of the notch 160 is not a concern, and the design at position 1 or position 3 is improved. The hinge support part 220 supports the hinge 300. The hinge support part 220 has a shape in which the U-shape is laid down horizontally, and holds the hinge so as to be rotatable by the lower rotating shaft 410 after sandwiching the hinge between both side surfaces. In addition, since the hinge support part 220 holds the rotating part of the hinge 300, the rotating part of the hinge 300 fits into the notch part 160 simultaneously with the hinge support part 220.

  The lower operation unit 230 performs an operation at position 2. An example of the lower operation unit 230 is a character keyboard. The imaging optical system 240 can be used for, for example, a camera that can be used at position 3 or video shooting. The battery pack 250 supplies power to the mobile terminal 10.

  The composite switch 260 has, for example, three button inputs in the center and both sides. The buttons on both sides can be applied to increase / decrease input of the volume when used as a telephone or as a music player, for example. When used as a camera, for example, it can be applied to zoom-in or zoom-out input. When used as an electronic book, for example, it can be applied to page feed or return input.

  The central button of the composite switch 260 can be applied to, for example, a press talk button or a voice dial button when used as a telephone. For example, when used as a camera, it can be applied to designation input of a wide-angle shooting mode. When used as an electronic book, for example, it can be applied to a character enlargement function button.

  The slide switch 265 performs an input operation by sliding. For example, it can be applied to the power button of the mobile terminal 10. For example, it can be applied to a shutter when used as a camera. Various other functions can be assigned to the composite switch 260 and the slide switch 265.

  5 to 14 sequentially show the movement of the upper housing 100 when the mobile terminal 10 is viewed from the side. In FIG. 5, the mobile terminal 10 is in the position 1 state. In this state, the upper surface of the upper housing 100 is denoted by B. In this state, the upper housing 100 and the hinge 300 are fixed. That is, the rotation of the upper casing 100 around the upper rotation shaft 420 is in a state of being suppressed.

  In FIG. 6, the upper housing 100 starts to open. The opening movement of the upper casing 100 is a rotational movement around the lower rotating shaft 410. In this state, the upper housing 100 and the hinge 300 are fixed.

  In FIG. 7, the upper casing 100 is perpendicular to the lower casing 200. That is, the angle formed by the long side of the hinge 300 and the upper casing facing surface of the lower casing 200 is 90 degrees. At this time, it is released. That is, the upper housing 100 can be rotated around the upper rotation shaft 420. If the upper casing 100 is moved further in the direction of expansion or the upper casing 100 is rotated about the upper rotation shaft 420, the fixing operation of the upper casing 100 and the hinge 300 once released becomes effective again.

  FIG. 8 shows a state in which the angle between the long side of the hinge 300 and the upper housing facing surface of the lower housing 200 is 90 degrees or more from the state of FIG. 7, that is, the upper housing 100 is further expanded. In this state, the mobile terminal 10 is in the position 2 state. In this state, the upper housing 100 and the hinge 300 are fixed in this state.

  9 shows a state in which the upper casing 100 is rotated around the upper rotation shaft 420 from the state of FIG. In this state, the mechanism for fixing the upper casing 100 and the hinge 300 is effective. However, although the mechanism to be fixed is effective, the fixing itself is not effective unless the upper housing 100 and the hinge 300 are positioned so as to be fixed. Therefore, in the state shown in FIG. 9, a rotational movement about the upper rotation shaft 420 of the upper housing 100 is possible.

  FIG. 10 shows a state where the upper casing 100 is further rotated from the state of FIG. FIG. 11 shows a state in which the upper housing 100 is further rotated from the state of FIG.

FIG. 12 shows a state where the upper housing 100 is further rotated from the state of FIG. 11 and the hinge 300 is fitted into the groove 150 of the upper housing 100. In this state, the upper casing 100 and the hinge 300 are fixed.

  FIG. 13 shows a state in which the upper casing 100 is moving in the closing direction with respect to the lower casing 200. In this state, the upper housing 100 and the hinge 300 are fixed.

  FIG. 14 shows a state in which the upper housing 100 is completely closed with respect to the lower housing 200. In this state, the upper casing 100 and the hinge 300 are fixed, and a mechanism for fixing the upper casing 100 and the lower casing 200 is also working. Here, the upper surface of the upper casing 100 changes from B to A. That is, this state becomes the position 3 state. Compared with the state of FIG. 5, the upper casing 100 is inverted and overlaid on the lower casing 200.

  FIG. 15 is an enlarged view of the vicinity of the side surface of the upper housing 100 in FIG. The hinge 300 is fitted in the groove 150 of the upper housing 100, and the upper surface of the hinge 300 is lower than the upper surface (operation surface) of the upper housing 100. That is, the thickness of the hinge 300 is thinner than the depth of the groove 150. Further, the cutout portion 160 of the upper housing 100 corresponds to the hinge support portion 220 and the protruding portion 210 of the lower housing 200. The level difference due to the notched portion of the notched portion 160 provided by the presence of the hinge support portion 220 is alleviated by the protruding portion 210.

  FIG. 16 shows a part of the mobile terminal 10 viewed from the direction a in FIG. FIG. 17 shows a part of the mobile terminal 10 viewed from the direction b in FIG. FIG. 18 shows the mobile terminal 10 viewed from the direction c in FIG.

  An electrode 310 is disposed on the upper surface of the hinge 300 and an electrode 320 is disposed on the lower surface. The electrodes 310 and 320 are connected to an electronic circuit inside the lower housing 200. Further, an electrode 170 and an electrode 175 are disposed on the groove bottom surface of the groove 150 of the upper housing 100. The electrode 170 is arranged so that it is positioned on the front side in the case of position 1 and the back side in the case of position 3, and the electrode 175 is arranged on the back side in the case of position 1 and on the front side when it is in position 3. Has been. The electrode 170 and the electrode 175 are connected to an electronic circuit inside the upper housing 100. Note that the electrode 310, the electrode 320, the electrode 170, and the electrode 175 are examples of contacts.

  When the mobile terminal 10 is in position 1 or position 2, the electrode 320 and the electrode 175 are connected as shown in the figure. On the other hand, when the mobile terminal 10 is in the position 3, the upper housing 100 is inverted, so that the electrode 310 and the electrode 170 are connected. That is, when the hinge 300 is fitted into the groove 150, the electrode 320 and the electrode 175 or the electrode 310 and the electrode 170 are connected. Since the electrode 170 and the electrode 175 are disposed on the bottom surface of the groove 150, there is an effect that the electrode is protected.

  Thus, in the portable terminal 10 of this embodiment, the combination of the electrodes connected by a position differs. Thereby, for example, a combination of electrodes to be connected can be detected and used as an element for determining the position. Further, the operation of the mobile terminal 10 can be varied depending on the combination of electrodes to be connected.

  For example, if the electrode 320 and the electrode 175 are connected and the rotation angle of the hinge 300 around the lower rotation shaft 410 is detected by another method, the mobile terminal 10 is detected as being in the position 1 and is carried. Application software as a telephone can be activated. Moreover, it can detect that the portable terminal 10 exists in the position 2, and can start application software as a portable information terminal. Alternatively, it is possible to detect that the electrode 310 and the electrode 170 are connected, and to start application software for watching TV or video. Arbitrary operations that differ depending on the position can be preferentially executed.

  A mechanism for fixing and releasing the upper casing 100 with respect to the hinge 300 and a mechanism for fixing and releasing the upper casing 100 with respect to the lower casing 200 will be described with reference to FIGS. As shown in the figure, the hinge 300 is provided with a magnet 330, and the magnet 180 and the magnet 182 are arranged in a portion (including a case where the upper casing 100 is opposed to the magnet 330). The magnet 330, the magnet 180, and the magnet 182 may be arranged on the opposite side of the side surface. In addition, a magnet 270 is provided in the center portion on the front side of the lower housing 200, and a magnet 184 is disposed in a portion facing the magnet 270 of the upper housing.

  For example, the magnet 330 and the magnet 270 may be permanent magnets. Magnet 180, magnet 182 and magnet 184 may be electromagnets, for example. By arranging the magnets in this way and performing control to reverse the polarity of the electromagnets, the upper housing 100 and the hinge 300 can be fixed and released using the attractive force or repulsive force between the magnets, Fixing and releasing from the lower housing 200 can be controlled. The upper housing 100 may include a control unit that reverses the polarities of the magnets 180, 182 and 184.

  Now, when the mobile terminal 10 is in position 1 or position 3, control is performed so that the magnet 180, the magnet 182 and the magnet 184 are not energized. If the magnetic core of the electromagnet is made of a ferromagnetic material such as iron, for example, the upper casing 100 and the hinge 300, and the upper casing 100 and the lower casing 200 are loosely fixed by the attractive force of the permanent magnets at the opposing positions.

  Here, for example, the slide switch 265 is operated, and a control command for applying a current in a direction to generate a repulsive force between the magnet 184 and the magnet 270 to the magnet 184 is given to the control unit. Then, a repulsive force exceeding a loose attractive force is generated between the magnet 184 and the magnet 270, the upper housing 100 and the lower housing 200 are released from being fixed, and the upper housing 100 is slightly opened by the repulsive force. Become. That is, for example, if such a function is given to the slide switch 265, a push-open function can be realized. At this time, the upper casing 100 and the hinge 300 are fixed by passing a current in a direction to generate an attractive force to the magnet 180 or the magnet 182 located at the position facing the magnet 330.

  Next, when the portable terminal 10 is in a state where the hinge 300 moves from the position 1 or the position 3 to a position (second position) perpendicular to the lower housing 200, that is, an operation of opening the upper housing 100 is performed. In this case, a current in a direction to generate an attractive force is passed through the magnet 180 or the magnet 182 located at a position facing the magnet 330. Thereby, the upper housing | casing 100 and the hinge 300 are fixed.

  When the hinge 300 is in a position (second position) perpendicular to the lower housing 200, the magnet 180, the magnet 182 and the magnet 184 are controlled not to be energized. As a result, the upper casing 100 and the hinge 300 are coupled with a low attractive force, and can be easily rotated by applying a small force. However, when it is detected that the upper casing 100 starts to rotate with respect to the hinge 300, an attractive force is generated in the magnet 180 or the magnet 182 that faces the magnet 330 when the upper casing 100 has finished rotating 180 degrees in the rotation direction. Flow current in the direction. As a result, the angle between the upper housing 100 and the hinge 300 is 0 degree (the fourth position or the fifth position), and the upper housing 100 and the hinge 300 are fixed.

  When the hinge 300 is at an angle exceeding 90 degrees with respect to the lower housing 200, the upper housing 100 is shifting to the position 2 state or is in the position 2 state. In this case, a current in a direction that generates an attractive force is passed between the magnet 330 and the magnet 180. Thereby, the upper housing | casing 100 and the hinge 300 are fixed.

  By controlling the polarity of the magnet as described above, it is possible to control the fixing or releasing of the hinge 300 and the upper housing 100 and the fixing or releasing (push open) of the upper housing 100 and the lower housing 200. Although the generation control of the attractive force and repulsive force by the electromagnet has been described here, the permanent magnet may be physically moved to control the attractive force and repulsive force between the magnets.

  In the above embodiment, the example in which the operation of the mobile terminal 10 is different depending on the connection between the two electrodes disposed on the hinge 300 and the two electrodes disposed on the bottom surface of the groove 150 has been described. The operation may be different. For example, the mobile terminal 10 includes a sensor that detects the direction of gravity, and detects the direction of the mobile terminal 10 detected by the sensor, that is, whether the main display unit 130 is in landscape orientation or portrait orientation, and varies application software to be activated. For example, the operation may be different. For example, the game mode may be automatically set for the landscape orientation and the book browsing mode for the portrait orientation.

  It is clear from the above description that the mobile terminal 10 of the present embodiment can be applied to various usage modes. For example, in position 1, telephone transmission / reception, mail check, voice memo transmission, electronic money application, entrance / exit management, TV remote control, music mobile phone, radio, recording, clock, simple calculator, and many other applications can be applied.

  In position 2, for example, mail transmission / reception, Internet search, electronic dictionary, web browsing, and other applications using a character keyboard (QWERTY keyboard) can be applied. In position 3, for example, applications such as camera or movie shooting, television or video viewing, games, map search, map navigation, learning, etc. can be applied in a landscape orientation. In the vertically oriented state, for example, applications such as comic browsing, electronic book reading, or electronic library browsing can be applied.

  FIG. 19 shows a case where the mobile terminal 10 is used as a television at position 3.
