Description

  The present invention relates to an electronic device in which a stand for standing is rotatably provided on a back surface of a device housing.

  In recent years, tablet personal computers (tablet PCs) having a touch panel type liquid crystal display and no physical keyboard are rapidly spreading. In general, tablet PCs may be operated while being held by hand or placed on a desk or the like, and when operated while placed on a desk or the like, a stand is used to stand up. May be used in a standing position.

  For example, Patent Document 1 discloses an electronic apparatus having a stand that is provided on the back surface of a stand so as to be rotatable via a hinge.

JP 2009-158669 A

  In the configuration described in Patent Document 1, when using a stand that is housed along the back surface of the electronic device, it is necessary for the user to hook the end of the stand with a fingertip or a nail and cause it from the back surface. . For this reason, for example, a user with a thick finger or a user with a short nail may not be able to raise the stand easily and smoothly.

  The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide an electronic apparatus that can use a stand easily and smoothly.

  The electronic device according to the present invention is rotatably connected to the device housing via a hinge portion, and can be rotated between a storage position along the back surface of the device housing and a standing position protruding from the back surface. An electronic device capable of holding the device housing in a standing posture by setting the stand to the standing position, and the stand is a support end side connected to the hinge portion. The first magnet and the second magnet are arranged so that the poles facing the back side of the device casing are different from each other, and the first magnet and the second magnet are provided side by side on the opposite open end side. The device casings have a polarity that attracts each other when facing the first magnet of the stand while the stand is in the storage position, and repels each other when facing the second magnet. The case side magnet and the machine A slide member provided to be slidable within the housing, and moving the housing-side magnet to a closed position facing the first magnet and an open position facing the second magnet; and sliding the slide member to the housing It has an operation part which moves a body side magnet to the closed position and the open position.

  According to such a configuration, when using the stand in the storage position, the casing-side magnet and the second magnet are simply moved by sliding the operation portion to move the casing-side magnet to the open position facing the second magnet. The stand pops up due to the repulsive force between the magnets. For this reason, the user can rotate the stand that has been popped up to the upright position by simply lifting it, and the stand can be used easily and smoothly. In addition, when the stand is in the storage position, the first magnet is attracted to the housing-side magnet, so that the storage position can be stably held.

  The housing side magnet may have a first elastic member that biases the slide member in a direction from the open position toward the closed position. If it does so, a case side magnet can be normally arranged in a closed position, a stand can be easily held in a stowed position, and it can be smoothly popped up from this state.

  The hinge portion may have an intermediate lock mechanism that holds the stand at a predetermined angular position between the storage position and the standing position. If it does so, the stand popped up by operation of an operation part can be held in that state, and it will be prevented that the stand which popped up closes in a stowed position again, and the operativity of a stand improves further.

  The hinge portion may have a second elastic member that urges the stand in the storage position in a rotation direction toward the standing position. If it does so, in addition to the repulsive force between a housing | casing side magnet and a 2nd magnet, a stand can be popped up more smoothly using the urging | biasing force by a 2nd elastic member.

  The intermediate lock mechanism is provided with a stand attachment portion that rotates around the axis of the hinge portion together with the stand, and a second cam surface that can slide in contact with a first cam surface provided on the stand attachment portion, A cam member in which the second cam surface is urged by the second elastic member in a direction close to the first cam surface in a state of being movable along the axial direction of the portion, and the second cam surface The stand may be held at the predetermined angular position by abutting and holding the first cam surface. Then, it becomes possible to hold the stand at a predetermined angular position with a simple structure using cam surfaces that are in sliding contact with each other.

  The hinge portion is configured so that a rotation torque between the storage position and the first angle position is from the first angle position to the standing position in a rotation direction in which the stand moves from the storage position to the standing position. The structure set smaller than the rotation torque in between may be sufficient. As a result, a smoother pop-up operation of the stand and improved stability at the standing position are achieved.

  The stand has the first magnet and the second magnet on one side of the open end, and has a third magnet or an adsorbed body on the other side of the open end, The housing may be configured to include the adsorbed body or the third magnet that adsorbs each other while facing the third magnet or the adsorbed body of the stand in a state where the stand is in the storage position. . If it does so, the shakiness of the stand in a storage position can be suppressed more.

  According to the present invention, when using the stand in the storage position, the casing-side magnet and the second magnet are simply moved by sliding the operation unit to move the casing-side magnet to the closed position facing the second magnet. The stand pops up due to the repulsive force between the two. For this reason, the user can rotate the stand that has been popped up to the upright position by simply lifting it, and the stand can be used easily and smoothly.

It is a figure which shows the state made to pop up, and FIG.4 (C) is a figure which shows the state which made the stand 14 the standing position. FIG. 5 is a schematic cross-sectional view taken along the line VV in FIG. 3 in a state where the stand 14 is in the storage position, and FIG. 6 is a diagram of VV in FIG. 3 in a state where the stand 14 is popped up. It is a schematic cross section along a line. 7 is a schematic cross-sectional view taken along the line VII-VII in FIG. 3 in a state where the stand 14 is in the storage position, and FIG. 8 is a view in FIG. 3 in which the stand 14 is popped up. It is a schematic cross section along a -VII line.

  As shown in FIGS. 3, 5, and 6, a first magnet (adsorption magnet) 24 </ b> N and a second magnet (on the right side in FIG. 3) are provided on one side (right side in FIG. 3) near the open end 14 b of the stand 14. (Repulsion magnet) 24S is provided side by side. The first magnet 24N and the second magnet 24S are set so that the poles facing the back surface 12a side of the device housing 12, that is, the inner surface 14c of the stand 14, are different from each other. In the present embodiment, the first magnet 24N closer to the inner side of the stand 14 is arranged so that the north pole faces the inner surface 14c, and the second magnet 24S closer to the outer side of the stand 14 faces the inner face 14c. It is arranged. That is, an S pole magnet can be attracted to the first magnet 24N, and an N pole magnet can be attracted to the second magnet 24S.

  A housing-side magnet 26S is provided in the recessed portion 20 of the device housing 12 at a position facing the first magnet 24N and the second magnet 24S of the stand 14 that are in the storage position. The case-side magnet 26S is arranged so that the south pole faces the inner surface 14c of the stand 14 (the surface of the recess 20). The casing-side magnet 26S is alternatively movable between a position facing the first magnet 24N and a position facing the second magnet 24S. The housing-side magnet 26S attracts the first magnet 24N and holds the stand 14 in the storage position (see FIGS. 4A and 5), and the stand that repels the second magnet 24S and is in the storage position. A pop-up function (see FIG. 4B and FIG. 6) for rotating 14 in the opening direction is generated.

  As shown in FIGS. 5 and 6, a slide member 32 that is slidable along the direction in which the first magnet 24 </ b> N and the second magnet 24 </ b> S are arranged (left-right direction in FIG. 5) is provided in the device housing 12. ing. A housing side magnet 26 </ b> S is held on one end side of the slide member 32. An operation portion 34 is integrally fixed to the other end side of the slide member 32. The operation unit 34 includes an operation knob 34 a that is slidably disposed in a recess 36 formed in the back surface 12 a of the device housing 12. The operation knob 34 a has a step that allows the user to hook a fingertip or a nail, and is a protrusion for sliding the housing-side magnet 26 </ b> S via the slide member 32.

  The slide amount of the slide member 32 is controlled by the slide position of the operation knob 34 a in the recess 36. The slide member 32 is slidable from a position (closed position) where the casing-side magnet 26S held on one end side faces the first magnet 24N of the stand 14 to a position (open position) facing the second magnet 24S. The operation knob 34 a may be provided not on the back surface 12 a of the device housing 12 but on the side surface.

  A coil spring (first elastic member) 40 is disposed between the other end surface of the slide member 32 on the operation unit 34 side and the support piece 38 provided on the device housing 12. The coil spring 40 constantly urges the slide member 32 so that the housing-side magnet 26S moves in the direction from the second magnet 24S on the proximal side of the operation knob 34a toward the first magnet 24N on the distal side. In a state where no external force is applied to the operation knob 34a, the slide member 32 is at the most advanced position by the biasing force of the coil spring 40, and the housing side magnet 26S faces the first magnet 24N (see FIG. 5). .

  As shown in FIGS. 3, 7, and 8, a third magnet 42 is provided on the other side (the left side in FIG. 3) near the open end 14 b of the stand 14. In the recess 20 of the device housing 12, an adsorbed body 44 is provided at a position facing the third magnet 42 of the stand 14 as the storage position. The attracted body 44 is a metal plate that can be attracted to a magnet. The third magnet 42 is attracted to the attracted body 44 when the stand 14 is in the storage position, and generates a holding function (see FIG. 7) that holds the stand 14 in the storage position. The attracted member 44 may be provided on the stand 14 side, and the third magnet 42 may be provided on the device housing 12 side.

  In the present embodiment, the adsorption force between the third magnet 42 and the object to be adsorbed 44 is set between the magnet and the metal, so that the attraction force is the first magnet 24N and the housing side that are attracted to each other. It is set smaller than the attractive force between the magnet 26S. In other words, it is preferable that the attractive force between the third magnet 42 and the attracted body 44 is set smaller than the repulsive force between the second magnet 24 </ b> S and the housing-side magnet 26 </ b> S that repel each other. . Of course, both the stand 14 side and the device housing 12 side may be configured by magnets that attract each other, and the attraction force may be set smaller than the repulsive force between the second magnet 24S and the housing side magnet 26S.

  FIG. 9 is an enlarged perspective view of a main part showing a state of the hinge part 18 in a state where the stand 14 is in the storage position, and FIG. 10 is a main part showing a state of the hinge part 18 in a state where the stand 14 is popped up. FIG. FIG. 11 is an enlarged perspective view of a main part showing a state of the hinge portion 18 in a state where the stand 14 is in an upright position.

  As shown in FIGS. 9 to 11, one hinge portion 18 connected to the support end portion 14 a on one side where the first magnet 24 </ b> N and the second magnet 24 </ b> S of the stand 14 are provided has a rotation shaft 46. And an intermediate lock mechanism 48 for holding the stand mounting portion 22 rotatable around the rotation shaft 46 at a predetermined angular position.

  The rotation shaft 46 is a shaft member that is connected and fixed to the device housing 12 (back cover 12c) so as to straddle the portion of the recess 20 in which the support end portion 14a of the stand 14 is accommodated (see also FIG. 3).

  The intermediate locking mechanism 48 moves the stand 14 at a predetermined angular position (for example, 10 degrees when the storage position is 0 degree) between the storage position (see FIG. 4A) and the standing position (see FIG. 4C). This is a mechanism that holds the pop-up position (see FIG. 4B). The intermediate lock mechanism 48 includes a stand attachment portion 22 and a cam member 50.

  The stand attachment portion 22 rotates around the axis of the rotary shaft 46, the rotary cylinder portion 52 provided rotatably around the axis of the rotary shaft 46, the mounting plate 54 protruding from the outer peripheral surface of the rotary cylinder portion 52, and the axis of the rotary shaft 46. The rotary cam portion 56 is provided so as to be capable of being connected and fixed integrally with the rotary cylinder portion 52 and the mounting plate 54. The mounting plate 54 is fastened and fixed to the support end portion 14a of the stand 14 using a fastener such as a screw (not shown). As a result, the stand 14 and the rotating cylinder portion 52, the mounting plate 54, and the rotating cam portion 56 of the stand mounting portion 22 rotate integrally around the rotation shaft 46. The rotating cam portion 56 has a first cam surface 56a on the end surface of the cylindrical portion in which the rotating shaft 46 is inserted. The first cam surface 56 a is an inclined surface that is inclined in the axial direction toward the circumferential direction of the rotation shaft 46.

  In the case of this embodiment, between the rotating cylinder part 52 and the rotating shaft 46, the stand 14 is in the direction from the storage position toward the standing position, from the storage position to the first angle position (pop-up position in this embodiment). Is set to be smaller than the rotational torque from the first angular position to the standing position. In other words, the rotational torque from the storage position of the stand 14 to the pop-up position is set to almost zero, while the maximum rotational torque is set to be generated at least in the standing position.

  The cam member 50 is a cylindrical member that is externally attached to the rotation shaft 46 so as not to rotate around the rotation shaft 46 and is movable in the axial direction, and is disposed adjacent to the rotation cam portion 56. Yes. The cam member 50 has a second cam surface 50 a that faces the first cam surface 56 a of the rotating cam portion 56 so as to be slidable on the end surface on the rotating cam portion 56 side. The second cam surface 50a is an inclined surface that is inclined in the axial direction toward the circumferential direction of the rotation shaft 46, and is symmetrical to the first cam surface 56a. A coil spring (second elastic member) 60 is provided between the end surface of the cam member 50 opposite to the rotating cam portion 56 side and the end surface of the end nut 58 screwed into the end portion of the rotating shaft 46. It is arranged. The coil spring 60 constantly urges the cam member 50 in the direction in which the second cam surface 50a is close to the first cam surface 56a.

  In addition, as shown in FIG. 3, the other hinge part 19 connected with the support end part 14a of the other side part side in which the 3rd magnet 42 of the stand 14 was provided is a rotating cam from one hinge part 18 mentioned above. In this configuration, the portion 56, the cam member 50, and the coil spring 60 are omitted. That is, although not specifically illustrated, the hinge portion 19 includes a rotation shaft 46 and a stand attachment portion 22 having a rotary cylinder portion 52 and an attachment plate 54. The hinge part 19 may have the same configuration as the hinge part 18.

  Next, the operation | movement which uses the stand 14 of the electronic device 10 is demonstrated.

  First, as shown in FIG. 4A, when the stand 14 is in the storage position, the slide member 32 is at the most advanced position by the biasing force of the coil spring 40 as shown in FIG. It is in the closed position facing the first magnet 24N on the stand 14 side. For this reason, an attractive force is generated between the housing-side magnet 26S and the first magnet 24N. Further, as shown in FIG. 7, the object to be attracted 44 faces the third magnet 42 on the stand 14 side, and an attracting force is generated in both. As a result, the both sides of the open end portion 14b of the stand 14 are attracted to the device housing 12 side, so that the stand 14 is held in the storage position in a stable state without rattling.

  In this state, the hinge portion 18 is in a position where the second cam surface 50a of the cam member 50 is in contact with the first cam surface 56a of the rotating cam portion 56 of the stand mounting portion 22 as shown in FIG. It is in. For this reason, the second cam surface 50a is elastically moved in the direction close to the first cam surface 56a by the biasing force of the coil spring 60, that is, in the opening direction from the storage position to the standing position via the first cam surface 56a. Is pressed. However, since the open end 14b side of the stand 14 is attracted and held to the device housing 12 as described above, the stand 14 is not opened by the pressing force of the second cam surface 50a against the first cam surface 56a. Absent.

  Next, when the stand 14 in the storage position is rotated to the standing position, the operation knob 34a is slid in a releasing direction (rightward in FIGS. 3 and 5) away from the stand 14. Thereby, as shown in FIG. 6, the slide member 32 slides against the urging force of the coil spring 40, and the housing side magnet 26S becomes the open position facing the second magnet 24S on the stand 14 side. For this reason, as shown in FIGS. 6 and 8, a repulsive force is generated between the housing-side magnet 26 </ b> S and the second magnet 24 </ b> S, and the attractive force between the third magnet 42 and the object to be attracted 44 is blocked. The open end 14b side of the stand 14 is raised (popped up).

  At this time, in the hinge portion 18, the second cam surface 50a presses the stand 14 in the opening direction from the storage position toward the standing position via the first cam surface 56a by the biasing force of the coil spring 60 as shown in FIG. (See the solid arrow in FIG. 9). For this reason, since the urging force of the coil spring 60 of the hinge portion 18 is applied together with the repulsive force between the housing-side magnet 26S and the second magnet 24S, the stand 14 is located between the third magnet 42 and the attracted member 44. Pops up reliably regardless of the adsorption power. Moreover, in the hinge portions 18 and 19, the rotational torque between the rotating cylinder portion 52 of the stand mounting portion 22 and the rotational shaft 46 is set to zero or very small from the storage position to at least the pop-up position. For this reason, the stand 14 can be popped up more smoothly.

  As the stand 14 pops up in this manner, the rotating cam portion 56 rotates together with the stand 14 in the hinge portion 18, and the first cam surface 56 a moves in a direction to retract from the second cam surface 50 a. Then, the second cam surface 50a moves in the axial direction so as to follow the first cam surface 56a while being in sliding contact with the first cam surface 56a by the urging force of the coil spring 60 (see the solid line arrow in FIG. 10). When the end surfaces of the cam member 50 and the rotating cam portion 56 come into contact with each other and the movement of the cam member 50 is restricted, the second cam surface 50a and the first cam surface 56a are completely engaged with each other as shown in FIG. Abut. As a result, since the rotation of the first cam surface 56a is restricted by the second cam surface 50a, the rotation in the direction returning to the storage position of the stand 14 fastened to the mounting plate 54 is restricted.

  As a result, the stand 14 is held in the pop-up position (intermediate lock state) as shown in FIGS. That is, in the electronic device 10, the stand 14 is automatically popped up and held at the pop-up position only by sliding the operation knob 34 a in the releasing direction from the state where the stand 14 is in the storage position.

  When the external force on the operation knob 34a is released, the sliding member 32 and the operation knob 34a slide in the holding direction by the urging force of the coil spring 40, and the housing side magnet 26S again becomes the closed position facing the first magnet 24N side. . However, since the stand 14 is held in the pop-up position, a sufficient space is generated between the housing-side magnet 26S and the first magnet 24N so that almost no attracting force is generated. It is also possible to prevent the camera from returning to the storage position again.

  After the stand 14 reaches the pop-up position, the open end 14b side is lifted with a fingertip or the like, and the stand 14 is rotated to the standing position shown in FIGS. 2 and 4C. As a result, the electronic device 10 can be held in an upright position via the stand 14. At this time, the hinge portions 18 and 19 are set so that the rotational torque between the rotary cylinder portion 52 of the stand mounting portion 22 and the rotational shaft 46 is maximized at least in the standing position. The standing position of the can be held stably without rattling.

  On the other hand, as shown in FIG. 4C, when the stand 14 in the standing position is rotated to the storage position, the open end 14b side of the stand 14 is pushed down with a fingertip or the like. Then, in the hinge part 18, the stand 14 rotates in the direction shown by a broken line arrow in FIG. 11 from the state at the standing position shown in FIG. As a result, the first cam surface 56a and the second cam surface 50a abut at the pop-up position shown in FIG. When the stand 14 is further pushed down from this state, the second cam surface 50a receives a pressing force from the first cam surface 56a, and the cam member 50 moves back in the axial direction (see the broken line arrow in FIG. 10). The state shown in FIG.

  At the same time, the first magnet 24N and the third magnet 42 on the open end 14b side of the stand 14 are attracted to the housing side magnet 26S and the attracted body 44 (see FIGS. 5 and 7). As a result, the stand 14 is again held in the storage position shown in FIG.

  As described above, in the electronic device 10 according to the present embodiment, the stand 14 is provided side by side on the open end 14b side opposite to the support end 14a side connected to the hinge portions 18 and 19. While having the 1 magnet 24N and the 2nd magnet 24S, the 1st magnet 24N and the 2nd magnet 24S are set so that the pole which faces the back surface 12a side of the apparatus housing | casing 12 may differ. Further, the device casing 12 attracts each other when facing the first magnet 24N in a state where the stand 14 is in the storage position, and has a polarity that repels each other when facing the second magnet 24S. 26S, a slide member 32 that is slidable within the device housing 12 and moves the housing-side magnet 26S to a closed position facing the first magnet 24N and an open position facing the second magnet 24S, and a slide member 32 has an operation unit 34 that slides 32 to move the housing-side magnet 26S to the closed position and the open position.

  Therefore, when using the stand 14 in the storage position, the casing-side magnet 26S is simply moved by sliding the operation knob 34a of the operation section 34 to move the casing-side magnet 26S to the open position facing the second magnet 24S. And the second magnet 24S cause the stand 14 to pop up. For this reason, the user can rotate the stand 14 to the upright position simply by lifting the open end 14b side of the stand 14 popped up, and the stand 14 can be used easily and smoothly. Further, when the stand 14 is in the storage position, the first magnet 24N is attracted to the housing-side magnet 26S, so that the storage position can be stably held.

  In addition, since the electronic device 10 is configured to hold the stand 14 with the attracting force of the magnet in the storage position and to pop up with the repulsive force of the magnet, the shape of the recess 20 is set to a shape that substantially matches the shape of the stand 14. It is possible to prevent the stand 14 from rattling at the storage position. In other words, for example, in a configuration in which the stand 14 is held by mechanical engagement means, an overstroke that normally takes a large rotation range of the stand 14 is required, but the electronic device 10 does not require this overstroke. Therefore, the apparatus housing 12 can be thinned.

  In the electronic device 10, the housing-side magnet 26 </ b> S has a coil spring 40 that biases the slide member 32 in a direction from the open position toward the closed position. For this reason, the casing-side magnet 26S can be placed in a closed position during normal times. Thereby, the stand 14 can be easily held in the storage position, and the pop-up operation can be smoothly performed from this state.

  In the electronic device 10, the hinge portion 18 includes an intermediate lock mechanism 48 that holds the stand 14 at a predetermined angular position between the storage position and the standing position, in this embodiment, the pop-up position. Thereby, the stand 14 popped up by the operation of the operation unit 34 can be held in that state, and the popped stand 14 is prevented from closing again to the storage position.

  In this case, the hinge portion 18 includes a coil spring 60 that urges the stand 14 in the storage position in the rotation direction toward the standing position. Thereby, in addition to the repulsive force between the housing side magnet 26S and the 2nd magnet 24S, the stand 14 can be popped up more smoothly using the urging force by the coil spring 60. Further, the intermediate lock mechanism 48 can more stably hold the stand 14 at the pop-up position.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.
