Description

  The present application relates to an openable electronic device.

  In recent years, notebook computers, mobile phones, electronic dictionaries, and other various electronic devices have become widespread (see, for example, Patent Documents 1-5).

Japanese Patent Laid-Open No. 10-11170 JP-A-9-259684 JP-A-5-298000 Japanese Patent Laid-Open No. 11-259208 JP 2002-229709 A

  Portable electronic devices are required to be thin. However, for example, electronic devices that handle various types of information such as notebook computers, mobile phones, and electronic dictionaries are arranged with keys for the user to input characters. The key is provided with a key stroke of about several millimeters so that the user can press it down with a finger. Therefore, for example, in an electronic device having an opening / closing structure in which one of two exteriors covers a key provided in the other exterior, such as a notebook computer, various parts such as a key are folded. This may be an obstacle to making the electronic device in a thin state thinner.

  Therefore, for example, various mechanisms such as a link mechanism and a cam mechanism can be considered as a mechanism for moving the component up and down in conjunction with the opening and closing operation. However, the link mechanism and the cam mechanism are easy to adopt for the connecting portion that connects the two exteriors via a single-axis hinge. For example, a liquid crystal panel like a notebook personal computer that has been proposed recently. When the LCD panel is oriented in the left-right direction, it can be used in electronic devices that have a 2-axis hinge that can be turned in the left-right direction as well as those that open and close with a single axis. It is not easy to raise and lower.

  Therefore, in the present application, even when the exteriors are connected by a multi-axis hinge, the parts on the surface of the other exterior covered by one exterior can be moved up and down in conjunction with the opening / closing operation of the exterior. A possible openable electronic device is disclosed.

  The present application discloses the following openable electronic device. That is, in the openable electronic device disclosed in the present application, one end is connected to the first exterior in which the component is disposed on the surface, the openable second exterior that covers the component, and the second exterior, A wire wound around the shaft by the opening / closing operation of the exterior, and an elevating mechanism for moving the component up and down in conjunction with the wire.

  In the case of the above openable electronic device, even when the exteriors are connected by hinges of multiple axes, the parts on the surface of the other exterior covered by one exterior are linked to the opening / closing operation of the exterior. Can be moved up and down.

  Hereinafter, embodiments will be described. The embodiment described below is merely an example, and the technical scope of the present disclosure is not limited to the following aspect.

FIG. 1 is a diagram showing the appearance of a notebook personal computer (hereinafter referred to as “PC”). The PC 1 is an example of an “open / close electronic device” in the present application, and includes a first exterior 2 in which electronic components such as a CPU (Central Processing Unit) and a memory are incorporated, and a second exterior 3 in which a liquid crystal panel 8 is provided. With. A large number of keys 4 (an example of “component” in the present application) are arranged on the surface of the first exterior 2. The first exterior 2 is connected to the second exterior 3 via a connection mechanism 5 having a biaxial hinge.

  FIG. 2 is a diagram showing a main part of the internal structure of the PC 1. The coupling mechanism 5 includes a first hinge 6 that forms a rotation axis parallel to the surface on which the keys 4 are arranged, and a second hinge that forms a rotation axis perpendicular to the surface on which the keys 4 are arranged. Hinge 7. The 1st hinge 6 is provided in the both ends of the support | pillar 22 which lies on the right and left. The second hinge 7 supports the column 22 at the center of the column 22. Therefore, the second exterior 3 can open and close the surfaces of the keys 4 arranged in the first exterior 2 by a rotation operation that rotates around the axis of the first hinge 6. . Further, the second exterior 3 can turn the display surface of the liquid crystal panel 8 left and right by a rotation operation that rotates about the axis of the second hinge 7.

  By the way, the PC 1 is provided with a wire 9 and a lifting mechanism 10. The wire 9 is routed inside the coupling mechanism 5 and inside the first exterior 2. The elevating mechanism 10 has a plate member 14 in which holes 11 into which the keys 4 are fitted are arranged. Compression springs 15 that push up the plate material 14 are arranged at the four corners of the plate material 14.

  A claw 16 that contacts the edge of the hole 11 of the plate member 14 is provided at the bottom of each key 4. Each key 4 is fitted into each hole 11 from below the plate member 14. Therefore, when the plate member 14 moves downward, the keys 4 are pushed down together with the claws 16 that are in contact with the edges of the holes 11.

  From the four corners of the plate member 14, projections 18 each having an inclined surface 19 that inclines obliquely with respect to the vertical direction of the PC 1, which is the up and down direction of the key 4, protrude laterally. The inclined surface 19 forms an obliquely upward inclined surface. A contact member 20 fixed to the wire 9 is disposed in the vicinity of each protrusion 18. When the wire 9 is pulled toward the coupling mechanism 5, the contact member 20 that moves together with the wire 9 approaches the inclined surface 19. When the wire 9 is pulled to the opposite side of the coupling mechanism 5 by the tension spring 25, the contact member 20 that moves together with the wire 9 moves away from the inclined surface 19.

  The contact member 20 is disposed along the left and right edges of the first exterior 2. On the other hand, the 2nd hinge 7 of the connection mechanism 5 exists on the centerline which divides the 1st exterior 2 into right and left. Therefore, the wire 9 is drawn to the second hinge 7 from the left and right edges of the first exterior 2 via the pulley 21 and is routed to the inside of the coupling mechanism 5.

  FIG. 3 is a view showing a state in which the wire 9 is routed inside the coupling mechanism 5. After passing through the second hinge 7, the wire 9 passes through the column 22 of the coupling mechanism 5 lying on the left and right. The wire 9 goes out of the support 22 through the holes 13 provided at the left and right ends of the support 22. The tip of the wire 9 is attached to the end of the first hinge 6 at both ends of the support post 22. The first hinge 6 is provided with a claw 17 for winding the wire 9. Therefore, when the second exterior 3 is moved back and forth and the axis of the first hinge 6 rotates, the wire 9 is wound around the claw 17 and wound around the axis of the first hinge 6. When the wire 9 is wound around the claw 17 and wound around the shaft of the first hinge 6, the contact member 20 fixed to the wire 9 approaches the inclined surface 19.

  FIG. 4 is a diagram showing the up / down state of the key 4. FIG. 4A shows the positional relationship between the contact member 20 and the inclined surface 19 of the protrusion 18. FIG. 4B shows the positional relationship between the key 4 and the plate material 14. In a state in which the wire 9 is entangled with the claw 17 and is not wound around the shaft of the first hinge 6, the contact member 20 is attracted to the tension spring 25 and separated from the inclined surface 19. Therefore, each key 4 pushed up by the push-up mechanism 23 provided in each key 4 protrudes from the surface of the first exterior 2 without being pushed down by the plate material 14 pushed up by the compression spring 15. (See “Key Protrusion” in FIG. 4).

  On the other hand, in a state where the wire 9 is wound around the claw 17 and is wound around the shaft of the first hinge 6, the contact member 20 is drawn toward the coupling mechanism 5 and contacts the inclined surface 19. When the contact member 20 is drawn toward the coupling mechanism 5 and contacts the inclined surface 19, the contact member 20 sandwiched between the inner surface of the first exterior 2 and the inclined surface 19 pushes down the plate material 14. Therefore, each key 4 is pushed down together with the plate material 14 by the claw 16 that contacts the edge of each hole 11 of the plate material 14 and is stored in the first exterior 2 (see “Key storage” in FIG. 4). reference).

  FIG. 5 is a first view showing the states of the lifting mechanism 10 and the coupling mechanism 5 together with the state of the PC 1. In a state where the PC 1 is opened, the wire 9 is entangled with the claw 17 and is not wound around the shaft of the first hinge 6, and the contact member 20 is attracted by the tension spring 25 and is separated from the inclined surface 19. Therefore, each key 4 protrudes from the surface of the first exterior 2.

  FIG. 6 is a second view showing the state of the lifting mechanism 10 and the connecting mechanism 5 together with the state of the PC 1. When the PC 1 is closed, the wire 9 is wound around the claw 17 and is wound around the shaft of the first hinge 6, and the contact member sandwiched between the inner surface of the first exterior 2 and the inclined surface 19. 20 pushes down the plate 14. Accordingly, each key 4 is housed in the first exterior 2.

In the PC 1, when the second exterior 3 is moved forward and the PC 1 is closed, the keys 4 are accommodated in the first exterior 2. Therefore, it is possible to design the PC 1 in the closed state as thin as possible. Further, in the PC 1 described above, when the second exterior 3 is moved later and the PC 1 is opened, each key 4 is protruded from the surface of the first exterior 2. Therefore, the user can easily press each key 4.

  In the lifting mechanism 10, the member connected to the second exterior 3 in order to raise and lower the key 4 is a wire 9. For example, a second hinge such as a link or a cam interlocking with the second exterior 3 is used. It is not a lifting mechanism that is difficult to rotate around the axis 7. Therefore, the lifting mechanism 10 can be applied to an electronic device such as the PC 1 having the connecting mechanism 5 that can direct the liquid crystal panel 8 in the left and right directions. However, the elevating mechanism 10 is not limited to application to an electronic device that can turn the liquid crystal panel 8 in the left and right directions like the PC 1, and for example, the second hinge 7 from the PC 1. The present invention can also be applied to an open / close electronic device that is connected by a single-axis hinge such that is omitted.

  In the lifting mechanism 10 described above, all the keys 4 are lifted and lowered together by the plate material 14. However, the lifting mechanism 10 lifts and lowers a part of the keys 4 arranged in the first exterior 2. There may be. Further, the elevating mechanism 10 may elevate and lower the key 4 with a member other than the plate material 14. The raising / lowering mechanism 10 may raise / lower each key 4 with the member which combined the bar material in the grid | lattice form, for example.

  The lifting mechanism 10 is not limited to application to an openable electronic device in which various electronic components such as the liquid crystal panel 8 are built in the second exterior 3. The lifting mechanism 10 can be applied to, for example, an openable electronic device that covers a key and a liquid crystal panel provided in a first exterior with a second exterior that is a simple plate-like cover. .

  The lifting mechanism 10 is applicable to various electronic devices other than the PC 1. Examples of electronic devices other than the PC 1 to which the elevating mechanism 10 can be applied include mobile phones, electronic dictionaries, and other open / close electronic devices including various open / close mechanisms.

  In the lifting mechanism 10 described above, the wire 9 is pulled by the tension spring 25. However, the wire 9 may be pulled by an elastic body such as rubber.

  FIG. 7 is a third view showing the state of the lifting mechanism 10 and the coupling mechanism 5 together with the state of the PC 1. As shown in FIG. 5, the first hinge 6 is provided with a pair of claws 17 entangled with the wire 9 symmetrically with the axis of the first hinge 6 interposed therebetween. Therefore, the wire 9 is not only when the second exterior 3 is moved forward and the PC 1 is closed, but also when the second exterior 3 is moved later and pushed to the back side of the first exterior 2. It will be in the state wound around the axis | shaft of the 1st hinge 6. FIG. Therefore, in the above-described PC 1, each key is used not only when the second exterior 3 is moved forward and the PC 1 is closed, but also when the second exterior 3 is folded back to the back side of the first exterior 2. 4 is accommodated in the first exterior 2. However, in the PC 1 described above, one of the pair of claws 17 provided symmetrically with the axis of the first hinge 6 interposed therebetween is omitted, and the second exterior 3 is folded back to the back side of the first exterior 2. In this case, the keys 4 may not be accommodated in the first exterior 2.

By the way, the following mechanism is provided in the 2nd hinge 7 with which said PC1 is equipped. FIG. 8 shows the second hinge 7 in detail. FIG. 8A shows the appearance of the second hinge 7. FIG. 8B shows the internal structure of the second hinge 7. The second hinge 7 is a member having a cylindrical shape, and is designed to fit into the hole of the column 22 of the coupling mechanism 5. Therefore, the support column 22 of the coupling mechanism 5 can rotate around the second hinge 7 around an axis orthogonal to the surface on which the keys 4 of the first exterior 2 are arranged. A hole 12 for inserting the wire 9 is provided at the center of the second hinge 7. In addition, a pair of raised portions 24 protruding in a mountain shape are disposed on the upper surface of the second hinge 7 with the hole 12 therebetween. The pair of raised portions 24 are arranged so as to be aligned along the front-rear direction of the PC 1. Inside the second hinge 7, a pair of tunnel-like grooves 26 are formed so as to penetrate obliquely from the middle of the hole 12 toward the outer peripheral surface of the second hinge 7 with the hole 12 interposed therebetween. A pair of groove | channel 26 is formed along the left-right direction of PC1. The groove 26 has a size capable of passing a single wire 9. Since the second hinge 7 has the hole 12, the raised portion 24, and the groove 26, the following functions are realized.

  FIG. 9 is a fourth view showing the state of the lifting mechanism 10 and the connecting mechanism 5 together with the state of the PC 1. For example, when the second exterior 3 is rotated clockwise around the axis of the second hinge 7 so that the liquid crystal panel 8 faces to the left, the wire 9 inserted into the hole 12 of the second hinge 7 is inserted. Rotates around the upper side of the second hinge 7 together with the support 22 of the coupling mechanism 5. However, since the pair of raised portions 24 are arranged on the second hinge 7 along the front-rear direction of the PC 1, the wire 9 routed laterally from above the hole 12 is raised. Ride on part 24. The wire 9 rides on the raised portion 24 except when the liquid crystal panel 8 faces directly in front or directly behind. While the wire 9 rides on the raised portion 24, the wire 9 pulls the contact member 20 toward the coupling mechanism 5 by the height of the raised portion 24. While the contact member 20 is being pulled toward the coupling mechanism 5, as described above, the contact member 20 pushes down the plate member 14, and the key 4 is accommodated in the first exterior 2.

  FIG. 10 is a fifth view showing the state of the lifting mechanism 10 and the connecting mechanism 5 together with the state of the PC 1. In the PC 1, when the second exterior 3 is turned counterclockwise around the axis of the second hinge 7 so that the liquid crystal panel 8 faces to the right, the wire 9 is raised as in the case of the right turn. 24, the contact member 20 pushes down the plate 14, and the key 4 is accommodated in the first exterior 2.

  In the lifting mechanism 10, the member connected to the second exterior 3 in order to raise and lower the key 4 is the wire 9, and thus the raised portion 24 as described above is provided on the second hinge 7. While the key 3 is facing sideways, the key 4 can be depressed to prevent the key 4 from contacting the second exterior 3.

  The lifting mechanism 10 can be modified as follows. FIG. 11 is a view showing a modified example of the up / down state of the key 4. FIG. 11A shows the positional relationship between the contact member 20 and the inclined surface 19 of the protrusion 18. FIG. 11B shows the positional relationship between the key 4 and the plate material 14. In this modification, the inclined surfaces 19 of the protrusions 18 provided at the four corners of the plate member 14 form an inclined surface that is inclined downward. Therefore, in the lifting mechanism 10 of this modification, the contact member 20 is attracted to the tension spring 25 and contacts the inclined surface 19. When the contact member 20 contacts the inclined surface 19, the contact member 20 sandwiched between the inner surface of the first exterior 2 and the inclined surface 19 pushes up the plate member 14, and the key 4 protrudes from the surface of the first exterior 2. (See “Key Protrusion” in FIG. 11).

  On the other hand, in a state where the wire 9 is wound around the claw 17 and wound around the shaft of the first hinge 6, the contact member 20 is drawn toward the coupling mechanism 5 side and is separated from the inclined surface 19. When the contact member 20 moves away from the inclined surface 19, the compression spring 15 pushes down the plate member 14, and the key 4 is accommodated in the first exterior 2 (see “key accommodation” in FIG. 11).

  In this modified example, the key 4 can be moved up and down in conjunction with the movement of the wire 9 as in the lifting mechanism 10 of the above embodiment.

Moreover, although said wire 9 was wound around the nail | claw 17 and was wound around the axis | shaft of the 1st hinge 6, you may wind as follows. FIG. 12 is a view showing a modification of the first hinge 6. The first hinge 6A according to the modified example is, for example, as shown in FIG.
Is provided at the end. When the second exterior 3A is opened and closed, the first hinge 6A rotates following the movement of the second exterior 3A. The end of the wire 9 is fixed to the first hinge 6A. The wire 9 enters the round shaft-like column 22 </ b> A through the hole 13 </ b> A provided in the column 22 </ b> A, and is drawn toward the second hinge 7. In the first hinge 6A according to this modification, when the first hinge 6A rotates, the wire 9 is wound around the support 22A. Even in the first hinge 6 </ b> A according to this modification, the wire 9 can be wound up following the opening and closing of the second exterior 3, similarly to the first hinge 6 of the above embodiment.

  FIG. 13 is a diagram illustrating an application example of the lifting mechanism 10. The above-described lifting mechanism 10 is, for example, an openable electronic device 1B having a connection mechanism in which the first exterior 2B and the second exterior 3B slide and rotate relatively as shown in FIG. It can also be applied to. That is, when the second exterior 3B covers the key 4B of the first exterior 2B, the contact member 20 pushes down the key 4B, and the second exterior 3B is slid to be the key 4B of the first exterior 2B. When the cover 4 is not covered, the contact member 20 moves away from the inclined surface 19 and the key 4B is raised, and when the second exterior 3B is rotated and a part of the key 4B of the first exterior 2B is covered, the wire 9 is raised. The contact member 20 may ride on the part 24 and press down the key 4B.

  By the way, although the said raising / lowering mechanism 10 raises / lowers the keys 4 and 4B which are examples of the "component" said by this application, you may raise / lower other various components. The elevating mechanism 10 may elevate and lower various components such as a speaker unit and an indicator lamp. FIG. 14 is a diagram showing an application example to a speaker unit. For example, the bass reflex type speaker 27 includes a speaker unit 28 and a housing 29. The bass reflex type speaker 27 emits the sound on the back side of the speaker unit 28 to the front side by the housing 29, and thereby amplifies the sound by the phase difference between the sound on the front side of the speaker unit 28 and the sound on the back side. It is aimed, and is particularly effective for amplification of bass. It is desirable that the space of the housing 29 on the back side of the speaker unit 28 has an appropriate volume corresponding to the output of the speaker unit 28. However, for example, in an electronic device that is required to be thin, such as a notebook computer or a tablet computer, it is difficult to secure an appropriate size space on the back side of the speaker unit 28. However, if the lifting mechanism 10 is applied to the lifting / lowering of the speaker unit 28, the speaker unit 28 can be protruded from the housing 29 when the second exterior 3, 3A, 3B is opened. If the speaker unit 28 protrudes from the housing 29, the space in the housing 29 on the back side of the speaker unit 28 increases. Therefore, the sound of the speaker 27 is improved.
