Description

  The present invention relates to a slide rotation hinge, and more particularly to a slide rotation hinge that slides and rotates a display unit of a portable electronic device such as a mobile phone, a PDA, or a portable game machine.

  2. Description of the Related Art Conventionally, there is a mobile phone that includes a slide mechanism that slides a display unit casing with respect to an operation unit casing to be in an extended state and a rotation mechanism that rotates the display unit casing from a vertically long state to a horizontally long state. When viewing TV on a mobile phone, the display housing is placed in the landscape orientation. FIG. 10 shows a conventional cellular phone disclosed in Patent Document 4 as an example. FIG. 10A shows the closed state of the display unit casing and the operation unit casing. FIG. 10B shows a state immediately before the slide is fully opened. FIG. 10C shows a state in which the display housing is rotated by 45 degrees. FIG. 10D shows a state in which the display housing is rotated 90 degrees. FIG. 10 (e) shows an exploded perspective view of the mobile phone. FIG. 11 shows an exploded perspective view of the lock unit.

  In this cellular phone, as shown in FIG. 10E, a display unit casing provided with a display unit such as a liquid crystal screen and an operation unit casing provided with an operation unit such as an input key are overlapped. Configured. The display unit housing and the operation unit housing are connected by a hinge device. The hinge device includes a rail unit that is fixed to the back surface of the display unit housing, a fixed unit that is fixed to the operation unit housing, and a middle that slides up and down on the rail unit and rotatably supports the fixed unit. It consists of a body. The display unit housing is rectangular, and a recess is provided on the back surface of the display unit housing to accommodate the rail unit. The operation unit casing is a rectangle having the same size as the display unit casing, and a recess capable of accommodating the fixed unit is provided in the vicinity of the end portion in the longitudinal direction.

  In the intermediate body, a slide movement unit that slides and a lock unit that slides and locks the slide movement at a predetermined position are arranged side by side in the slide movement direction, and a rotation unit is arranged on the back of the slide movement unit. . An electronic circuit in the display unit housing and an electronic circuit in the operation unit housing are electrically connected through a cable through a hole provided in the rail unit, the intermediate body, and the fixed unit. Each component of the rail unit is attached to a rectangular plate-shaped base that is slightly smaller than the display unit housing. On two long sides of the base of the rail unit, straight guide rails are provided in parallel to each other. Retaining prevention bodies are provided at both ends of each guide rail.

  As shown in FIG. 11, the base of the lock unit is a rectangle that is long in the slide width direction, and U-shaped guide locking portions are provided at both left and right ends. A guide member having a U-shaped cross section formed of a resin material is attached to each guide locking portion symmetrically. The guide member has a guide groove formed in a straight line in the sliding direction on the inner side. The guide grooves of the two guide members are configured to be parallel to each other in a state where the guide members are attached to the guide locking portions. At the upper right position of the base of the lock unit, there is provided a U-shaped rotation restricting protrusion protruding upward. A slide lock recess for slide lock is formed on the inner surface of the lock member in the left-right direction. On the upper right side of the base of the lock unit, a guide hole for attaching the pressing member so as to be linearly movable in the left-right direction and a shaft support hole for rotatably attaching the rotating member are provided in order from the inside to the outside.

  In the pressing member, a straight pressing surface is formed on the left side surface (inner side surface) in the sliding direction, and a curved guide surface is formed on the lower side of the right side surface. A guide protrusion is formed on the back surface of the pressing member to engage with the guide hole of the base of the lock unit. When the guide protrusion engages with the guide hole, the pressing member moves in a straight line from side to side without rotating. The rotating member is formed in a shape in which a part of a circle is cut out, and a convex pressing guide surface is formed at a position connecting the cutout portion to the outer circumference of the circle. An interlocking protrusion for interlocking with the link arm is formed on the back surface of the rotating member. An interlocking recess is provided at the end of the link arm on the base side. The interlocking recess is configured to engage with the interlocking protrusion of the rotating member, so that the link arm and the rotating member are always rotated.

  In the closed state shown in FIG. 10A, the upper position of the rail unit is engaged with the intermediate body positioned above the operation unit casing. At this time, the intermediate lock unit and the slide moving unit are connected so as not to be separable, and the rotation cam is restricted from rotating with respect to the rotation base. The rotation restricting member is biased rightward by a rotation restricting spring, and the rotation restricting protrusion on the right side of the rotation restricting member is in contact with the inside of the U-shaped portion of the rotation restricting protrusion on the upper right side of the lock member. . For this reason, both rotation control protrusions are mutually locked, and the lock unit and the slide moving unit are integrated so that they cannot be separated in the sliding direction.

  Here, the lock unit and the slide movement unit are connected by a link arm via a rotation unit and a fixed unit. For this reason, when the lock unit and the slide movement unit are separated and moved, the rotation unit and the link arm rotate in conjunction with each other. However, in a state where the lock unit and the slide moving unit cannot be separated, the rotation unit and the link arm cannot rotate, and their rotation is restricted.

  As shown in FIG. 10B, when the display unit casing is slid upward with respect to the operation unit casing, the rail unit guided by the intermediate body slides upward. Since the rotation restriction by the rotation restriction member is continuously performed during the sliding movement, the fixed unit cannot rotate with respect to the intermediate body. Further, the slide urging spring is urged in the closing direction until the intermediate point is reached, and when the user releases the hand in this state, the slide slidably moves to the closed state. When the intermediate point is crossed, it is urged in the opening direction and automatically slides to the fully open state even if the user releases the hand. Here, just before the slide opening operation is completed, the lock member begins to be caught in the space between the lock member and the pressing member.

  When the rail unit slides to the uppermost position and the slide opening operation is completed, the lock member is completely sandwiched in the space between the lock member and the pressing member, and a state in which these functions can be performed in series. Further, when shifting to the fully open position, the rotation restriction release protrusion comes into contact with the inclined surface of the rotation restriction member, and further moves in a straight line from here to the rotation restriction release protrusion so that the rotation restriction release protrusion is against the urging force of the rotation restriction spring. The member is moved in a straight line to the left in the width direction to shift to a fully open state. As a result, the rotation restricting protrusion of the rotation restricting member does not come into contact with the rotation restricting protrusion of the lock unit, and the lock unit and the slide moving unit can be separated. For this reason, the link arm and the rotary unit can be operated, and the slide moving unit and the fixed unit can be rotated by the rotary unit. By shifting to this state, the display unit housing can be rotated with respect to the input housing.

  When the rotating cam starts to rotate with respect to the rotating base, the angle regulating member moves outward in the width direction, and the roller rides on the guide surface from the recess. At this time, due to the rotation of the rotating cam, the fixed base fixed to the rotating cam also rotates, and the link arm whose one end is pivotally supported by the fixed base also rotates around the rivet from the straight state in the width direction of the hinge device. That is, the rotation center of the fixed base, the rotation center of the rivet that is rotatably supported by the fixed base and the tip of the link arm, and the rotation of the rivet that is rotatably supported by the lock unit at the lock unit. Since the U-shaped link connecting the center in this order is configured, the link arm also rotates when the fixed base rotates by this link function.

  When the link arm rotates, the rotating member in which the interlocking protrusion is engaged with the interlocking recess of the link arm is rotated. Due to the rotation of the rotating member, the pressing guide surface of the rotating member presses the curved guide surface of the pressing member, and thereby the pressing member moves in the width direction in a direction approaching the lock member. When the pressing member moves, the locking member is pressed against the pressing surface of the pressing member and moves in the width direction in a direction approaching the slide lock concave portion of the lock member, and the lock convex portion of the lock member contacts the slide lock concave portion of the lock member. Mating. Thereby, the lock member provided in the rail unit and the lock member provided in the lock unit are caught, and the lock unit is slide-locked to the rail unit so that the lock unit does not slide.

  As shown in FIG. 10C, when the display unit housing and the operation unit housing are further rotated, the slide moving unit further slides with respect to the rail unit by the action of the link arm. As shown in FIG. 10 (d), when the display unit housing and the operation unit housing are further rotated, the slide moving unit is further slid relative to the rail unit by the action of the link arm, and can be rotated to the slide moving unit. The center of rotation of the fixed unit attached to the rail unit is located at the center position of the rail unit.

  At this time, the roller fits into the recess of the rotating cam and is fixed in a state rotated 90 degrees. Further, the link arm is also rotated 90 degrees to be in a straight line in the sliding direction of the hinge device. When the rotation angle approaches 90 degrees due to the biasing force of the bumper spring, the roller on the guide surface tries to fall into the recess, so it rotates naturally and rotates at a rotation angle of 90 degrees. Will settle down. In this way, the entire mobile phone is in a T-shaped viewing state. When returning from the viewing state to the open state, the reverse operation is performed. The viewing state shown in FIG. 10 (d) is changed to the open state through the rotation state shown in FIG. 10 (c).

  When returning from the open state to the closed state, the reverse operation is performed. From the open state to the closed state shown in FIG. 10A through the slide state shown in FIG. When the sliding movement starts from the open state toward the closed state, the rotation restricting member that has been pressed to the left by the rotation restriction releasing protrusion is released from the pressure of the rotation restriction releasing protrusion. At this time, the rotation restricting member is engaged with the rotation restricting protrusion by the urging force of the rotation restricting spring, and the lock unit and the slide moving unit are locked in a state where they cannot be separated. For this reason, it will be in the rotation control state which a link arm and a rotation unit cannot operate | move. Until the intermediate body slides to the middle point of the rail unit until the intermediate body slides to the middle point of the rail unit, it tries to return to the open state by the biasing force of the spring. Automatically slides to the closed state by force.

  In this way, sliding opening / closing of the display unit casing and the operation unit casing and 90 ° rotation of the display unit casing can be realized. While the display unit housing and the operation unit housing are slid, the rotation of the display unit casing is unintentionally rotated without being intentionally rotated. The slide can be opened and closed. In addition, after shifting to the fully open state, the display unit housing can be rotated with respect to the operation unit housing. At this time, since the slide moving unit rotates while sliding in the return direction due to the lock unit lock and the link arm, the center position in the longitudinal direction of the display unit housing is 90 ° rotated. And the display unit housing is symmetrical.

  In this state, since the display unit is horizontally long, the user can view the television or the like in an easy-to-view state. In this way, the display case does not rotate as if it protrudes to the left or right, and the entire mobile phone can be in a well-balanced viewing state in which it is T-shaped. During the rotation from the fully open state to the viewing state rotated 90 degrees, the amount of slide movement is regulated by the link arm, so that stable rotation and sliding can be realized. A support unit for rotating and supporting the display unit housing on the back side is not necessary. Since only the display unit housing and the operation unit housing are visible on the appearance, and the hinge device does not appear outside, the mobile phone is simple and beautiful. Hereinafter, some examples of the related art related to the slide rotation mechanism of the display unit will be given.

  The “mobile communication terminal” disclosed in Patent Document 1 improves operability by positioning an operation unit below the center of the screen when the screen is horizontally long for TV reception or the like. As shown in FIG. 12 (a), the support shaft that rotatably supports the second housing portion having the display screen portion with respect to the first housing portion having the operation portion is the second housing. The part can be moved in a direction substantially perpendicular to the support shaft.

  The “mobile phone” disclosed in Patent Document 2 can change the orientation of the display unit. As shown in FIG. 12B, the main body unit rotatably supports the display unit. When the display unit is rotated to change the direction, the operation unit slides and protrudes from the main body unit. When the display unit is rotated to return its orientation, the operation unit is stored in the main body unit.

  In the “slide device” disclosed in Patent Document 3, the display unit smoothly slides and rotates with respect to the operation unit, and is click-engaged and positioned at a predetermined position. As shown in FIG. 12 (c), it is a slide device that slidably connects an operation unit and a display unit. A guide rail is provided in the display unit, and a slide unit that is guided by the guide rail and slides is provided in the operation unit. A click engagement portion is provided at a predetermined position of the guide rail. An engagement pin that engages with the click engagement portion is provided on the slide portion. The engagement pin is elastically pressed by the pin pressure unit.

The “hinge mechanism” disclosed in Patent Document 4 can change the liquid crystal screen between a vertically long state and a horizontally long state. A hinge mechanism for connecting the display unit casing and the operation unit casing is provided at a portion where the display unit casing and the operation unit casing overlap. A slide rail is fixed to the display housing. The intermediate body engages with the slide rail and slides on the slide rail. The fixing unit is fixed to the operation unit casing. At the rotary connection part, the fixed part is rotatably connected to the intermediate body.

  However, the conventional sliding rotary hinge has the following problems. The lock mechanism for preventing the rotation during the sliding operation and the sliding operation during the rotation is complicated, and the hinge device cannot be thinned.

  1 to 5, the slider plate 1 is a substrate fixed to the display unit housing. The guide rail 2 is a guide member fixed to both sides of the slider plate. The combination spring 4 is a set of coil springs that connect the slider plate and the intermediate plate. The spring retaining pin 5 is a pin for fixing one end of the assembled spring to the slider plate. The spring retaining pin 6 is a pin for fixing the other end of the assembled spring to the intermediate plate. The rotation guide pin 7 is a pin that is movably held in the groove of the intermediate plate and guided to the groove of the rotation plate. The rotating shaft 12 is a rotating shaft for rotating operation that passes through the intermediate plate and is fixed to the rotating plate.

There is a through hole through the cable in the center.

  The intermediate plate 13 is a member that connects the rotating plate and the slider plate by a sliding operation and a rotating operation. The rotating plate 14 is a substrate fixed to the operation unit casing. The rotation spring 15 has one end fixed to the rotation plate and the other end fixed to the intermediate plate, and is a spring that assists the rotation operation. The spring retaining pin 16 is a pin that fixes the rotating spring to the rotating plate. The sleeve 17 is a cylinder through which the rotation guide pin passes. The tap pin 18 is a screw hole fixed to the rotating plate. The curved groove 19 is a groove provided in the rotating plate for guiding the rotation guide pin. The linear convex portion 21 is a linear portion whose edge is parallel to the slide rail among the convex portions provided on the slider plate, and the edge hits the linear notch portion of the rotating shaft during the sliding operation to prevent rotation. It is a part for. The inclined convex part 22 is a part of the convex part provided on the slider plate, the edge of which is inclined with respect to the slide rail, and the part of the edge that hits the rotation axis during the rotational operation and prevents the sliding operation It is.

The blindfold 24 is an L-shaped bent portion provided at the end of the intermediate plate, and is a blindfold for preventing the inside from being seen.

  The function and operation of the slide rotation hinge in the first embodiment of the present invention configured as described above will be described. First, an outline of the slide rotation hinge will be described with reference to FIG. A state in which the display unit casing is superimposed on the operation unit casing (fully closed state) is as shown in FIG. When the display unit casing is slid with respect to the operation unit casing to reach the maximum extension state, the state is as shown in FIG. In this state, when the display unit housing is rotated in-plane by 90 degrees, the state is as shown in FIG. The slider plate 1 shown in FIGS. 1D and 1E is fixed to the display unit housing. The slider plate 1 is attached and fixed to the display unit housing through screws or the like through a plurality of through holes provided in the slider plate 1. A guide rail 2 that guides the sliding movement of the intermediate plate 13 is fixed to the slider plate 1.

  The rotating plate 14 shown in FIG. 1 (e) is fixed to the operation unit casing. The slider plate 1 may be fixed to the operation unit casing, and the rotating plate 14 may be fixed to the display unit casing. The intermediate plate 13 shown in FIGS. 1D and 1E is slidably combined with the slider plate 1 and is slidable relative to the slider plate 1. The intermediate plate 13 is rotatably coupled to the rotating shaft 12 fixed to the rotating plate 14 and is rotatable with respect to the rotating plate 14. A rotating shaft 12 that is a shaft for rotating operation passes through the intermediate plate 13 and is fixed to the rotating plate 14 by caulking or the like. A tap pin 18 is fixed to the rotating plate 14 by caulking or the like, and a tap groove is formed in the inner hole of the tap pin 18. The rotation plate 14 is fixed to the operation unit housing with screws using the tap pins 18.

  The rotation guide pin 7 is swingably held in the groove of the intermediate plate 13, passes through the curved groove 19 of the rotation plate 14, the spring 15 for rotation, and the sleeve 17 in this order, and rotates through the sleeve 17. It is connected to one end of the spring 15 for use. The other end of the rotation spring 15 is fixed to the rotation plate 14 with a spring retaining pin 16. The rotation guide pin 7 moves along the curved groove 19 of the rotation plate 14 while moving along the groove of the intermediate plate 13 to guide the rotation of the intermediate plate 13. Depending on the shape of the curved groove 19, the amount of deflection of the rotating spring 15 changes. When the rotation guide pin 7 is at both ends of the curved groove 19, the rotation spring 15 presses the rotation guide pin 7 against the end of the curved groove 19, so that the rotation guide pin 7 is held stably. When the rotation guide pin 7 is in the center of the curved groove 19, the rotation spring 15 is compressed and acts to push the rotation guide pin 7 in the direction of either end of the curved groove 19. Help.

  One end of the assembled spring 4 is fixed to the slider plate 1 by a spring retaining pin 5 by caulking or the like. The other end of the assembled spring 4 is fixed to the intermediate plate 13 with a spring retaining pin 6 by caulking or the like. When in the fully closed state and in the extended state, the assembled spring 4 presses the intermediate plate 13 against the end of the slider plate 1, so that it is stably held. When the intermediate plate 13 is in the central portion of the slider plate 1, the combination spring 4 is compressed and acts to push the intermediate plate 13 toward either end of the slider plate 1 to assist the sliding operation.

  During the slide operation, the rotation operation is blocked by the rotary shaft 12 and the linear convex portion 21, but it can be rotated at the slide position where the maximum extension state is achieved. During the rotating operation, the sliding operation is blocked by the rotating shaft 12 and the inclined convex portion 22, but it can be slid at the rotational position where it is in the vertically long state.

  When the rotating operation is blocked or the sliding operation is blocked, the slider plate 1 may be damaged because the rotating shaft 12 hits the slider plate 1. In order to prevent the appearance surface (surface exposed to the outside) of the slider plate 1 from being damaged, at least one of the surfaces of the slider plate 1 and the rotating shaft 12 facing each other is covered with a protective member such as a resin. Also, in order to prevent the outer surface of the intermediate plate 13 (the surface exposed to the outside) from being scratched by the rotating operation of the rotating plate 14, the intermediate plate 13 faces the rotating plate 14, The portion exposed to the outside is recessed and separated so as to escape from the rotating plate 14 from other portions.

  Next, the sliding operation will be described with reference to FIG. In the fully closed state shown in FIG. 2A, the assembled spring 4 is in an open state, and the intermediate plate 13 is pressed above the slider plate 1. Therefore, the display unit casing and the operation unit casing are stably closed. At this time, since the convex portion of the slider plate 1 is in contact with the rotating shaft, the slider plate 1 is in a state where it cannot rotate.

  When the display unit housing and the operation unit housing are slid by applying a force, the slider plate 1 moves upward in the drawing as shown in FIG. Therefore, in order to further slide the display unit casing and the operation unit casing, it is necessary to apply more force. Also at this time, since the convex portion of the slider plate 1 is in contact with the rotating shaft, the slider plate 1 is in a state where it cannot rotate.

  If the slide operation is continued and the intermediate portion of the slide stroke is exceeded, the combination spring 4 changes in the opening direction, so that the combination spring 4 applies a force in a direction that supports the slide operation. A sliding operation can be performed only by applying a weak force or without applying a force, and the extended state shown in FIG. The assembled spring 4 is in an open state, and the intermediate plate 13 is pressed below the slider plate 1. Therefore, the display unit casing and the operation unit casing maintain a stable open state. At this time, since the linear convex portion 21 of the slider plate 1 does not come into contact with the rotating shaft 12, the intermediate plate 13 can be rotated.

  As shown in the cross-sectional view of FIG. 2D, the rotating shaft 12 is in contact with the edge of the linear convex portion 21 of the slider plate 1 in the fully closed state and during the slide. If it is attempted to rotate in this state, the edge of the linear convex portion 21 collides with the rotating shaft 12, so that the rotating operation is prevented. As shown in the cross-sectional view of FIG. 2 (e), in the extended state, the edge of the linear convex portion 21 and the edge of the inclined convex portion 22 of the slider plate 1 are separated from the rotation shaft 12, so that the rotation operation also slides. Operation is also possible. Further, in the middle of the rotation, since the edge of the inclined convex portion 22 of the slider plate 1 is in contact with the rotary shaft 12, the sliding operation is prevented.

  Next, the rotation operation will be described with reference to FIG. In the extended state, when a force is applied to rotate the display unit casing in-plane with respect to the operation unit casing, the slider plate 1 and the intermediate plate 13 are moved to the rotating plate 14 as shown in FIG. Rotate against. The rotation guide pin 7 moves along the curved groove 19 of the rotation plate 14. At this time, as shown in FIG. 3C, since the edge of the inclined convex portion 22 of the slider plate 1 hits the rotating shaft 12, the sliding operation cannot be performed. When the rotation guide pin 7 is in the center of the curved groove 19, the rotation spring is compressed, and the rotation guide pin 7 is pushed in the direction of either end of the curved groove 19 to assist the rotation operation. When the display unit casing is further rotated, as shown in FIG. When the rotation guide pin 7 comes to the end of the curved groove 19, the rotation spring presses the rotation guide pin 7 against the end of the curved groove 19, so that the rotation guide pin 7 is held stably.

  The example in which the inclined convex portion 22 is provided as a structure for preventing the sliding operation during the rotating operation has been described. However, this portion may have an arc shape as shown in FIG. Alternatively, a linear or curved edge connected to the edge of the linear convex portion at a right angle or an acute angle may be used. In other words, any shape that does not hinder the rotation of the rotating shaft 12 and has a shape in which the tip of the linear convex portion 21 is in contact with the circumferential portion of the rotating shaft 12 is acceptable. These are collectively referred to as a slide prevention convex portion. In addition, the position where the slide prevention convex portion is provided has been described as an example of the position where the rotary shaft 12 comes in the maximum extended state, but may be the position where the rotary shaft 12 comes in the fully closed state, or may be provided in both positions. Also good. Furthermore, it can also be provided at an intermediate position. However, if the rotation is performed at an intermediate position, the slide cannot be completely prevented during the rotation. Therefore, it is necessary to provide a mechanism such as a click stop so as to suppress the slide operation.

  The rotation angle has been described as an example of 90 degrees, but may be smaller than 90 degrees. For example, in order to rotate by 60 degrees, the curved groove 19 may be made a length corresponding to 60 degrees. In order to rotate to an angle larger than 90 degrees, such as 180 degrees or 360 degrees, the shape of the intermediate plate 13 or the rotating plate 14 is changed so that the curved groove 19 has a length corresponding to the rotation angle. Or, a lever, a link mechanism, a crank mechanism, or the like can be used to rotate the short curved groove 19 to a large angle.

  Next, protection of the external surface of the slider plate will be described with reference to FIG. The upper half of the back side of the slider plate 1 is a portion (appearance surface) that can be seen as the back side of the display unit housing in the maximum extension state. This portion may come into contact with the rotating shaft 12 when the casing is bent during the sliding operation. If it comes in contact, it will be scratched and will look bad. In order to avoid this, the surface of the rotating shaft 12 and the slider plate 1 facing each other is covered with a protective material such as resin. For example, it coats with a fluororesin. Both may be covered, or only one of them may be covered. Further, the edge of the linear convex portion 21 and the slide-preventing convex portion of the slider plate 1 has a function of blocking rotation and sliding, so that it may come into contact with the rotating shaft and be damaged. In order to avoid this, a resin film is placed on both or one of the edge and the rotating shaft. The elasticity of the resin film can prevent the metal member from being scratched.

  Next, protection of the outer surface of the intermediate plate will be described with reference to FIG. In the horizontally long state shown in FIG. 5A, about half of the back side of the intermediate plate 13 is a portion (appearance surface) that can be seen as the back side of the display unit housing, as shown in FIG. 5B. This portion comes into contact with the rotating plate 14 during the rotation operation, so that it is scratched and looks bad. In order to avoid this, as shown in FIG. 5 (b), the intermediate plate 13 is recessed from the other part so that the part that becomes the external surface is escaped from the rotary plate 14 as shown in FIG. Release. The boundary between the contacted part and the recessed part is as shown in FIGS. Further, a blindfold 24 of an L-shaped end is provided at the end of the intermediate plate 13 to make it blindfold. Since the inside of the intermediate plate 13 is not visible, the appearance is improved. In addition, a through hole is provided in the central portion of the rotating shaft 12 so that a cable that electrically connects the upper housing and the lower housing is passed.

  As described above, in the first embodiment of the present invention, during the sliding operation of the slide rotary hinge, the edge of the linear convex portion of the slider plate hits the linear notch of the rotary shaft of the rotary plate, and the rotary plate rotates.

  The function and operation of the slide rotation hinge in the second embodiment of the present invention configured as described above will be described. First, an outline of the slide rotation hinge will be described with reference to FIG. The slide rotation hinge holds the display unit case slidably with respect to the operation unit case, and allows the display unit case to rotate in-plane up to 90 degrees with respect to the operation unit case in the maximum extension state. To do. In the fully closed state, the slide rotation hinge is as shown in the perspective view of FIG. A display unit housing is mounted on the slider plate 1. The rear surface of the hinge portion is as shown in the perspective view of FIG. An operation unit casing is attached on the rotating plate 14. An intermediate plate 13 is slidably attached to the slider plate 1, and is further attached to the rotating plate 14 so as to be rotatable about the rotating shaft 12. A rotation mechanism is mounted on the intermediate plate 13. The rotation mechanism includes a rotation prevention plate that engages with a rotation prevention pin of the rotation plate 14 so as to prevent the rotation operation during the slide operation, and a slide prevention that prevents the slide operation from hitting the rotation shaft 12 of the rotation plate 14 during the rotation operation. Pin 3 is provided. The slider plate 1 is provided with a cut-and-raised projection for removing the rotation prevention plate from the rotation prevention pin in the maximum extension state.

  As shown in FIG. 6 (c), an L-shaped blindfold 24 is provided at the end of the intermediate plate 13 to provide blindfold. Since the inside of the intermediate plate 13 is not visible, the appearance is improved. In addition, a through hole is provided in the central portion of the rotating shaft 12 so that a cable that electrically connects the upper housing and the lower housing is passed.

  Next, the function of each component of the slide rotation hinge will be described with reference to FIGS. The slider plate 1 is attached and fixed to the display unit housing through screws or the like through a plurality of through holes provided in the slider plate 1. A guide rail 2 that guides the sliding movement of the intermediate plate 13 is fixed to the slider plate 1. A rotation prevention pin 9 and a rotation prevention plate 10 are provided to prevent rotation so that the slider plate 1 does not rotate during the sliding operation. As shown in FIG. 8A, the rotation prevention pin 9 passes through the arc-shaped groove of the intermediate plate 13 and is fixed to the rotation plate 14 by caulking or the like. During the rotation operation, the arc-shaped groove provided in the intermediate plate 13 freely moves back and forth. However, during the slide operation, the rotation cannot be performed by the concave portion provided in the rotation prevention plate 10, so that the rotation operation is blocked.

  A part of the slider plate 1 is bent into an L-shape, and a cut-and-raised protrusion is provided. When the slider plate 1 slides and reaches a maximum extension state, the cut-and-raised protrusion pushes the rotation prevention plate 10 and the rotation prevention state is Canceled. During the rotating operation, the slider plate 1 rotates together with the intermediate plate 13. A slide blocking pin 3 is fixed to the slider plate 1 by caulking or the like so that the slider plate 1 does not slide during the rotating operation. Even if the slide operation is attempted during the rotation operation, the slide operation is prevented because the slide prevention pin 3 hits the rotation shaft 12. Since the rotary shaft 12 is cut into an oval shape, the slide blocking pin 3 can pass through the side surface of the rotary shaft 12 during a sliding operation.

  As shown in FIG. 8A, the rotating shaft 12, which is a rotating operation shaft, passes through the intermediate plate 13 and is fixed to the rotating plate 14 by caulking or the like. A tap pin 18 is fixed to the rotating plate 14 by caulking or the like, and a tap groove is formed in the inner hole of the tap pin 18. The rotation plate 14 is fixed to the operation unit housing with screws using the tap pins 18. During the sliding operation, the intermediate plate 13 is held by the rotation plate 14 by the rotation prevention pin 9 and the rotation prevention plate 10 and slides relative to the slider plate 1. During the rotation operation, the slider plate 1 is held by the slide prevention pin 3 and the rotation shaft 12 and rotates with respect to the rotation plate 14.

  As shown in FIG. 8B, the rotation guide pin 7 is swingably held in the groove of the intermediate plate 13, and the curved groove 19, the rotation spring 15 and the sleeve 17 of the rotation plate 14 are arranged in this order. It penetrates and is connected to one end of the rotation spring 15 through a sleeve 17. The other end of the rotation spring 15 is fixed to the rotation plate 14 with a spring retaining pin 16. The rotation guide pin 7 moves along the curved groove 19 of the rotation plate 14 while moving along the groove of the intermediate plate 13 to guide the rotation of the intermediate plate 13. Depending on the shape of the curved groove 19, the amount of deflection of the rotating spring 15 changes. When the rotation guide pin 7 is at both ends of the curved groove 19, the rotation spring 15 presses the rotation guide pin 7 against the end of the curved groove 19, so that the rotation guide pin 7 is held stably. When the rotation guide pin 7 is in the center of the curved groove 19, the rotation spring 15 is compressed and acts to push the rotation guide pin 7 in the direction of either end of the curved groove 19. Help.

  As shown in FIG. 8 (c), one end of the assembled spring 4 is fixed to the slider plate 1 with a spring retaining pin 5 by caulking or the like. The other end of the assembled spring 4 is fixed to the intermediate plate 13 with a spring retaining pin 6 by caulking or the like. When in the fully closed state and in the extended state, the assembled spring 4 presses the intermediate plate 13 against the end of the slider plate 1, so that it is stably held. When the intermediate plate 13 is in the central portion of the slider plate 1, the combination spring 4 is compressed and acts to push the intermediate plate 13 toward either end of the slider plate 1 to assist the sliding operation.

  As shown in FIG. 8D, the rotation prevention plate 10 is fixed to the intermediate plate 13 so as to be able to rotate about the shaft pin 8 as a rotation axis. The shaft pin 8 is fixed to the intermediate plate 13 by caulking or the like. The holding spring 11 has one end fixed to the intermediate plate 13 and the other end fixed to the rotation prevention plate 10 as shown in FIG. The rotation prevention plate 10 is pushed in the direction of the rotation prevention pin 9 so that the rotation prevention plate 10 does not come off the rotation prevention pin 9. During the sliding operation, as shown in FIG. 8 (e), the concave portion of the rotation prevention plate 10 is fitted with the rotation prevention pin 9 to prevent the rotation operation of the intermediate plate 13. When the slider reaches the maximum extension state by sliding, one end of the rotation prevention plate 10 is pushed by the cut and raised protrusion of the slider plate 1 and is slightly rotated, and the recess of the rotation prevention plate 10 is rotated as shown in FIG. Is disengaged from the rotation prevention pin 9 and the intermediate plate 13 can be rotated.

  Next, the slide operation and the rotation operation will be described with reference to FIG. In FIG. 9, the slider plate 1 is drawn as a transparent material for the sake of explanation. As shown in FIG. 9A, in the fully closed state, the assembled spring 4 is in an open state, and the intermediate plate 13 is pressed above the slider plate 1. Therefore, the display unit casing and the operation unit casing are stably closed. At this time, since the rotation prevention pin 9 is fitted in the recess of the rotation prevention plate 10, the intermediate plate 13 is held by the rotation plate 14. Therefore, the slider plate 1 cannot be rotated.

  When the display unit housing and the operation unit housing are slid by applying a force, the slider plate 1 moves upward in the drawing as shown in FIG. 9B, and the combination spring 4 is slightly closed. Therefore, in order to further slide the display unit casing and the operation unit casing, it is necessary to apply more force. Also at this time, since the rotation prevention pin 9 is fitted in the recess of the rotation prevention plate 10, the intermediate plate 13 is held by the rotation plate 14, and the slider plate 1 cannot rotate.

  If the slide operation is continued and the intermediate portion of the slide stroke is exceeded, the combination spring 4 changes in the opening direction, so that the combination spring 4 applies a force in a direction that supports the slide operation. A sliding operation can be performed only by applying a weak force or without applying a force, and the extended state shown in FIG. 9C is obtained. The assembled spring 4 is in an open state, and the intermediate plate 13 is pressed below the slider plate 1. Therefore, the display unit casing and the operation unit casing maintain a stable open state. At this time, one end of the rotation prevention plate 10 is pushed by the cut and raised protrusion of the slider plate 1 to rotate slightly, and the concave portion of the rotation prevention plate 10 is detached from the rotation prevention pin 9 so that the intermediate plate 13 can be rotated. It becomes. In the extended state, the rotation guide pin 7 is at the end of the curved groove 19, and the rotation spring 15 presses the rotation guide pin 7 against the end of the curved groove 19, so that it is stably held. The rotating spring 15 is not visible in FIG.

  When a force is applied so that the display unit housing rotates in-plane with respect to the operation unit housing in the extended state, the slider plate 1 and the intermediate plate 13 are moved to the rotating plate 14 as shown in FIG. Rotate against. The rotation prevention pin 9 moves in the arc-shaped groove of the intermediate plate 13, and the rotation guide pin 7 moves along the curved groove 19 of the rotation plate 14. At this time, the slide blocking pin 3 is in contact with the circumference of the rotary shaft 12, and there is no degree of freedom in the sliding direction, so a sliding operation cannot be performed. When the rotation guide pin 7 is in the center of the curved groove 19, the rotation spring 15 is compressed, and the rotation guide pin 7 is pushed in the direction of either end of the curved groove 19 to assist the rotation operation. When the display unit casing is further rotated, as shown in FIG. When the rotation guide pin 7 comes to the end of the curved groove 19, the rotation spring 15 presses the rotation guide pin 7 against the end of the curved groove 19, so that the rotation guide pin 7 is stably held.

  The rotation angle has been described as an example of 90 degrees, but may be smaller than 90 degrees. For example, in order to rotate by 60 degrees, the curved groove 19 has only to be 60 degrees long. In order to rotate to an angle larger than 90 degrees, such as 180 degrees or 360 degrees, the shape of the intermediate plate 13 or the rotating plate 14 is changed so that the curved groove 19 has a length corresponding to the rotation angle. Or, a lever, a link mechanism, a crank mechanism, or the like can be used to rotate the short curved groove 19 to a large angle.

  The protection of the outer surface of the intermediate plate will be described. In the horizontally long state, about half of the back side of the intermediate plate 13 is a portion (appearance surface) that can be seen as the back side of the display unit housing. This portion comes into contact with the rotating plate 14 during the rotation operation, so that it is scratched and looks bad. In order to avoid this, the part of the intermediate plate 13 facing the rotating plate 14 that is the appearance surface is recessed from the other part so as to escape from the rotating plate 14 and separated. Further, an L-shaped end portion is provided at the end of the intermediate plate to make it blindfolded. Since the inside of the intermediate plate becomes invisible, the appearance is improved.

  As described above, in the second embodiment of the present invention, during the sliding operation, the rotation prevention plate engages with the rotation prevention pin of the rotation plate to prevent the rotation operation, and in the maximum extended state, the cutting plate provided on the slider plate. The raising projection part removes the rotation prevention plate from the rotation prevention pin so as to be rotatable, and during the rotation operation, the slide prevention pin hits the rotation axis of the rotation plate so as to prevent the slide operation. The locking mechanism becomes simple, the hinge device becomes thinner, and the mobile phone can be made thinner.

  The slide rotation hinge of the present invention is optimal as a hinge that slides and rotates a display unit of a portable electronic device.
