Description

  The present invention relates to a portable electronic device such as a mobile phone, a PDA, and a game machine.

  A portable electronic device having two housings connected so as to be foldable is known (Patent Document 1). In the portable electronic device of Patent Document 1, a connection protrusion is formed in one housing, and a connection recess in which the connection protrusion is received is formed in the other housing, and two housings are formed in the connection protrusion and the connection recess. The body is connected.

  Each casing is configured by fixing two case members facing each other across an electronic component such as a circuit board. The facing direction of the two case members is the same as the direction in which the two housings face each other in the closed state. The two case members have a shape in which the casing is divided substantially at the center in the thickness direction of the casing (the direction facing the other casing in the closed state). That is, each case member is formed with an accommodation recess that is recessed on the side facing the other case member. The opening of the housing recess is formed to be equal to or wider than the bottom surface of the housing recess.

  Here, in the case where the connection concave portion is formed, a connection concave portion having a concave side (opposite side) facing the case where the connection protrusion is formed in the closed state may be formed. In this case, the connecting recess is generally configured by an outer peripheral surface of the case member disposed on the opposite side of the two case members.

JP 2006-238204 A

  For the purpose of improving the airtightness and strength of the casing, the case member on the opposite side (back side) to the opposite side may be formed to a depth equivalent to the thickness of the casing. However, it is difficult to apply a case member having such a depth to a housing in which a connection recess having a recess on the opposite side is formed. The reason for this will be described with reference to the drawings in the embodiment as well, but the outline is as follows.

  In the case member on the back side, if the connecting concave portion is formed by bending and extending the side surface of the accommodating concave portion, an undercut portion is formed, and molding is difficult. In addition, an electronic component must be accommodated obliquely from the opening of the accommodation recess in the portion of the accommodation recess that overlaps the connection recess, and the operation is difficult. If there is no space for housing electronic components in the area overlapping the connecting recess due to difficulty in molding and work, the space in the housing cannot be used effectively, and consequently the size of the portable electronic device is increased. Invite.

  As described above, in a case in which a connecting recess having a concave on the opposite side is formed, if an integrally formed case member having a depth is used, the formation of the connecting recess and the effective use of the space are made compatible. Is difficult.

  The objective of this invention is providing the portable electronic device which can make formation of a connection recessed part and effective utilization of a space compatible.

In other words, the mobile phone 1 has the first housing 3 and the second housing 5 that are coupled so as to be relatively rotatable about the rotation axis RA, and can transition between an open state and a closed state. Each of the first housing 3 and the second housing 5 is connected by a connecting portion 6 at each end. In the closed state, the first housing 3 and the second housing 5 are overlapped. In the open state, the surfaces facing each other in the closed state of the first housing 3 and the second housing 5 are separated from each other, and the first housing 3 and the second housing 5 are arranged substantially in parallel. The 1st housing | casing 3 and the 2nd housing | casing 5 are each formed in the substantially thin rectangular parallelepiped shape, and a mutual outline substantially corresponds in a closed state.

  The first housing 3 includes, for example, a microphone 87 for calling (see FIG. 10), a built-in antenna 81 for communication (see FIG. 10), a speaker 85 for notification (see FIG. 3), and an imaging unit 89 (see FIG. 10), an operation unit 7 (FIG. 1) for receiving a user operation is provided. The operation unit 7 includes a plurality of keys 35. The second housing 5 is provided with, for example, a speaker 83 for calling (see FIG. 10) and a display unit 9 (FIG. 1) for displaying an image.

  In the following, in the first housing 3 and the second housing 5, the sides facing each other in the closed state and the back side thereof may be referred to as the front side and the back side.

The connecting portion 6 is formed in a cylindrical shape with the rotation axis RA as an axis, and includes a first outer portion 51 and a second outer portion 53 that rotate relative to each other around the rotation axis RA. The first outer portion 51 includes the first housing 3
The second outer portion 53 is a part of the second housing 5. For example, two first outer portions 51 are provided in the direction of the rotation axis RA, and the second outer portion 53 is disposed between the two first outer portions 51. The first outer portion 51 and the second outer portion 53 are formed to have substantially the same diameter and are arranged coaxially, and constitute a single cylindrical shape as a whole. The diameters of the first outer portion 51 and the second outer portion 53 are smaller than the sum of the thickness of the first housing 3 and the thickness of the second housing 5 and larger than the thickness of the second housing 5.

  Further, as shown in FIG. 2, the first outer portion 51 and the second outer portion 53 are arranged so that the surface position on the back surface side of the second housing 5 substantially coincides with the back surface of the second housing 5.

In the first housing 3, a connecting recess 3 a (FIG. 6) for housing the second outer portion 53 so that the surface position on the back side of the second outer portion 53 substantially coincides with the rear surface of the second housing 5. Reference) is formed. In other words, the second outer portion 53 constitutes a connecting protrusion disposed in the connecting recess 3a, and the first housing 3 and the second housing 5 rotate relative to each other about the rotation axis RA that penetrates the connecting protrusion. By this, it is connected so that it can fold between an open state and a closed state.

  A hinge unit (not shown) is disposed in the first outer portion 51 and the second outer portion 53 to enable relative rotation around the rotation axis RA of the first housing 3 and the second housing 5. For example, although not particularly illustrated, the hinge unit is fixed to the first case 3 and the second part 5 and is connected to the first part so as to be rotatable about the rotation axis RA. And a second part. Alternatively, the hinge part is a shaft member that is inserted in the direction of the rotation axis RA with respect to the first housing 3 and the second housing 5, and is at least one of the first housing 3 and the second housing 5. It can be rotated. A signal line that connects the electronic circuit in the first housing 3 and the electronic circuit in the second housing 5 is also inserted into the first outer portion 51 and the second outer portion 53.

  FIG. 3 is an exploded perspective view of the first housing 3 as viewed from the front side. FIG. 4 is an exploded perspective view of the first housing 3 as seen from the back side. However, the disassembled parts are different between FIG. 3 and FIG.

  The mobile phone 1 includes a main board assembly 22, a camera unit 24 (FIG. 4), a sub board assembly 25, and a battery 27, which are stacked in order from the front case 11 inside the first housing 3. (FIG. 3).

  The inner case 13 is generally formed in a box shape with the front case 11 side opened, and is erected on the front case 11 side at the base portion 13v facing the back side of the main board 23 and the like, and at the periphery of the base portion 13v. Wall portion 13w. In other words, the inner case 13 has a first recess 13r (FIG. 3) that opens to the front side. An opening for taking in and out the battery 27 is formed in the base portion 13v.

  The front case 11 is generally formed in a box shape thinner than the inner case 13 with the inner case 13 side opened. The front case 11 covers the inner case 13 from the front side, covers the front side of the inner case 13 and surrounds the front side portion of the wall portion 13w.

The rear case 15 is generally formed in a box shape thinner than the inner case 13 with the inner case 13 side opened. An opening for taking in and out the battery 27 is formed on the rear side of the rear case 15. The rear case 15 covers the inner case 13 from the back side, covers the back side of the inner case 13, and surrounds the back side portion of the wall portion 13w.

  The lid 17 is formed in a substantially plate shape having a shape and size substantially the same as the opening on the back side of the rear case 15. The lid 17 is disposed in the opening on the back side of the rear case 15 and closes the opening of the base portion 13v of the inner case 13.

  Thus, the inner case 13 is wrapped by the front case 11, the rear case 15, and the lid body 17. That is, the front case 11, the rear case 15, and the lid body 17 constitute an outer casing 10 (FIG. 5) that wraps the inner case 13 that is an inner casing.

  The front case 11, the inner case 13, the rear case 15, and the lid body 17 are each mainly formed of, for example, a nonconductive resin. The inner case 13 is integrally formed. The front case 11, the inner case 13, and the rear case 15 are fixed to each other by, for example, screws or engaging portions or both. The lid 17 is detachably fixed to the inner case 13 or the rear case 15 or both by an engaging portion or the like.

  As shown in FIG. 3, the front case 11 exposes a plurality of keys 35 that accept user operations. The plurality of keys 35 are provided on the front case 11, for example. For example, the front case 11 includes a case main body 11a formed in a frame shape and a key component 11b bonded to the case main body 11a so as to close the opening of the case main body 11a. The key component 11b is formed by being formed of a material having relatively low rigidity, or by being thin, or both, so that the key component 11b can be easily bent with the user's pressing. Has been. The plurality of keys 35 are formed by forming an index (unevenness, pattern, etc.) indicating the pressed position on the key component 11b.

  The main board assembly 22, the camera unit 24, and the sub board assembly 25 are sandwiched by the front case 11 and the inner case 13 in the stacking direction of these members. Specifically, these members are sandwiched between the front case 11 and the base portion 13v of the inner case 13 on both sides of the first housing 3 in the longitudinal direction. The battery 27 is fitted into the inner case 13 and is prevented from falling off from the inner case 13 by the lid body 17.

  As shown in FIG. 3, the main board assembly 22 includes a main board 23, a shield case 21, a flexible printed wiring board (FPC) 43 (see FIG. 5), and a key sheet, which are sequentially stacked from the rear case 15 side. 19.

  The main board 23 is constituted by, for example, a rigid circuit board based on a hard resin. The main board 23 has a first mounting surface 23a (FIG. 3) on the front case 11 side and a second mounting surface 23b on the back side thereof. A plurality of electronic components 29 are provided on the first mounting surface 23a and the second mounting surface 23b.

  The shield case 21 is made of, for example, metal. Alternatively, the shield case 21 is configured by providing a conductive layer such as a metal layer on the surface of a non-conductive substrate such as a resin. The shield case 21 is connected to the ground layer of the main board 23.

  As shown in FIG. 4, the sub board assembly 25 includes a sub board 26 and a frame 28 that are sequentially stacked from the rear case 15 side.

The sub-board 26 is constituted by, for example, a rigid circuit board based on a hard resin. The sub-board 26 has a third mounting surface 26a on the front case 11 side and a fourth mounting surface 26b on the back side thereof. A plurality of electronic components 29 are provided on the third mounting surface 26a and the fourth mounting surface 26b.

  An external connector 65 as the electronic component 29 is mounted on the third mounting surface 26 a of the sub substrate 26. The external connector 65 is for connecting the mobile phone 1 to another electronic device. A hole 13j for exposing the external connector 65 to the outside is formed in the wall 13w of the inner case 13. The end of the external connector 65 on the opening side is disposed in the hole 13 j together with the end of the sub-board 26.

  The frame 28 is made of, for example, resin. The frame 28 fixes the sub board 26 and the camera unit 24 to the main board assembly 22. For example, the frame 28 holds the sub board 26 by an engaging portion (not shown). The frame 28 is attached to the main board 23 while sandwiching the camera unit 24 with the main board 23.

  The camera unit 24 is arranged with the lens 24a (FIG. 4) side facing the base portion 13v of the inner case 13. A hole 13g for exposing the lens 24a is formed in the base 13v. The camera unit 24 receives light from the subject through the hole 13g and images it.

  Fig.5 (a) is typical sectional drawing of the 1st housing | casing 3 in the Va-Va line | wire of FIG. FIG. 5B is an enlarged view of the region Vb in FIG. FIG. 5C is an enlarged view of the region Vc in FIG.

  As shown in FIG. 5A, the FPC 43 is provided with a plurality of switches 41, for example. The switch 41 is, for example, a pressing switch having a fixed contact 45 and a dome-shaped movable contact 47 that covers the fixed contact 45.

  The key sheet 19 is made of, for example, a non-conductive elastic member having a water shielding property (not permeable to water) such as rubber. The key sheet 19 covers the plurality of switches 41. At the position of the switch 41 on the key sheet 19, a pusher 19g protruding toward the switch 41 is formed. The pressing force of the user is concentrated at the center of the movable contact 47 by the pusher 19g.

  As shown in FIG. 5B, a groove 13e surrounding the opening 13h on the front case 11 side formed by the wall 13w is formed on the top of the wall 13w on the front case 11 side. On the other hand, the key sheet 19 has a packing portion 19e extending over the outer peripheral edge. The key sheet 19 is attached to the inner case 13 by press-fitting the packing portion 19e into the groove portion 13e. As a result, the first recess 13 r (FIG. 3) of the inner case 13 is sealed by the key sheet 19.

  Further, as shown in FIG. 5C, the inner case 13 is provided with a groove 13 f surrounding the opening on the lid 17 side of the inner case 13 on the lid 17 side. On the other hand, the lid 17 has a packing portion 17f that is bonded to the lid body 17a of the lid 17 and extends along the outer periphery of the lid body 17a. The lid 17 is attached to the inner case 13 and hermetically seals the inner case 13 by press-fitting the packing portion 17f into the groove 13f.

In the sealed space formed by the inner case 13, the key sheet 19 and the lid body 17, the FPC 43, the shield case 21, the main board 23, the sub board assembly 25 and the battery 27 are accommodated. In other words, the main substrate 23 and the like are accommodated in the first recess 13r sealed by the key sheet 19.

  FIG. 6 is an exploded perspective view of the first housing 3 as viewed from the connecting portion 6 side. FIG. 7 is a perspective view of the vicinity of the connecting portion 6 between the inner case 13 and the rear case 15 as viewed from the inside of the housing. In FIG. 6, the lid 17 and the key component 11b of the front case 11 are not shown. Moreover, the 1st outer part 51 of the 1st housing | casing 3 is a member fixed to the case main body 11a of the front case 11 (refer FIG. 3), and illustration is abbreviate | omitted in FIG.

  The connection recess 3 a in which the second outer portion 53 is disposed is formed in the inner case 13 and exposed from an opening 10 h (see FIG. 9) formed in the exterior housing 10. The connection recess 3 a is formed by the outer peripheral surface of the inner case 13 with the front side (side facing the second housing 5 in the closed state) as a recess. Specifically, the connecting recess 3a is configured by forming a corner on the rotation axis RA side and the front side of the inner case 13 into a notch shape. For example, the inner surface (concave surface) of the connecting recess 3 a is formed substantially concentrically with the outer peripheral portion of the second outer portion 53 so as to face the outer peripheral surface of the second outer portion 53 with a substantially constant minute gap.

  The connecting recess 3a is provided adjacent to the first recess 13r on the rotation axis RA side of the first recess 13r. As shown in FIG. 7, a partition wall 13x is formed between the first recess 13r and the connection recess 3a. That is, the first recess 13r is not expanded to the area on the back side (rear case 15) side of the connection recess 3a. In other words, the connecting recess 3a and the first recess 13r do not overlap in the facing direction in the closed state of the first casing 3 and the second casing 5.

  A method for assembling the first housing 3 will be described.

  In the first housing 3, first, the main board assembly 22, the camera unit 24, and the sub board assembly 25 are fixed to each other to form an assembly. Specifically, while engaging the camera unit 24 between the main board 23 of the main board assembly 22 and the frame 28 of the sub board assembly 25, the engaging portion 28f of the frame 28 is engaged with the edge of the main board 23. . In the following description, the assembled assembly excluding the key sheet 19 is referred to as an internal assembly 67 (FIGS. 3 and 4).

  Next, the internal assembly 67 is stored in the first recess 13r through the opening 13h of the inner case 13. Here, the main board 23, the shield case 21, and the like have a size that extends across the inner surface of the wall 13 w of the inner case 13. In addition, the region where the external connector 65 and the external connector 65 of the sub-board 26 are mounted protrudes from the main board 23 in a plan view of the main board 23 (as viewed in a direction orthogonal to the main surface of the main board 23). . Therefore, the internal assembly 67 has a shape that does not fit in the opening 13 h of the inner case 13 in a plan view of the main board 23. That is, the internal assembly 67 cannot be inserted into the inner case 13 from the opening 13h in a state where the main board 23 is parallel to the base portion 13v of the inner case 13.

  Therefore, the internal assembly 67 is inserted into the inner case 13 from the opening 13h in a state where the main board 23 is inclined with respect to the base portion 13v. Specifically, first, the external connector 65 side of the internal assembly 67 is inserted into the opening 13h, and further, the external connector 65 is inserted into the hole 13j. Thereafter, the side of the internal assembly 67 opposite to the external connector 65 is inserted into the inner case 13 through the opening 13h. That is, the main board 23 is changed from a state inclined with respect to the base portion 13v to a parallel state.

At this time, the main substrate 23 or the shield case fixed to the main substrate 23 abuts on the wall portion 13w of the inner case 13 or the like. Thereby, the main board 23 is positioned with respect to the inner case 13 in the direction along the main surface of the main board 23.

  When the internal assembly 67 is accommodated in the inner case 13, the key sheet 19 is then attached to the inner case 13. Then, the front case 11, the inner case 13, and the rear case 15 are fixed.

  Here, it is assumed that the first recess 13r is extended to the back side of the connection recess 3a without forming the partition wall 13x (FIG. 7) between the first recess 13r and the connection recess 3a. Think about etc. In this case, an electronic component cannot be put in the expanded portion in a direction orthogonal to the base portion 13v of the inner case 13, and the electronic component must be put obliquely toward the rotation axis RA. Further, if a part of the internal assembly 67 on the side of the rotational axis RA is disposed in the expanded portion, the part on the side of the rotational axis RA must first be put into the opening 13h. This is incompatible with the assembly method in which the external connector 65 is inserted first. Furthermore, since the expanded part becomes an undercut part in injection molding, formation is difficult. If the connecting recess 3a is formed of a member different from the inner case 13, it is difficult to improve the strength and sealing performance of the housing. However, if an electronic component is not arranged on the back side of the connection recess 3a, the space in the housing cannot be effectively used, and the mobile phone 1 is increased in size.

  Therefore, in the mobile phone 1, electronic components are arranged on the back side of the connecting recess 3a as follows.

  FIG. 8 is an exploded perspective view of the inner case 13 on the connecting portion 6 side and the back side. 9 is a cross-sectional view taken along line IX-IX in FIG.

  A second recess 13 i is formed on the back side of the inner case 13. A vibrator 54 is accommodated in the second recess 13i. The second recess 13 i is closed by the inner lid 55 and is also closed by the double-sided tape 56 and the outer lid 57 (see also FIG. 4). Specifically, it is as follows.

  The second recess 13i is formed at a position overlapping the connecting recess 3a in plan view of the first housing 3 (as viewed in the direction facing the second housing 5 in the closed state). More specifically, as shown in FIG. 9, in the second recess 13i, a part of the connecting part 6 side overlaps a part of the connecting recess 3a on the first recess 13r side. The second recess 13i opens on the back side, in other words, on the side opposite to the opening direction of the first recess 13r. For example, the second recess 13i is formed in a substantially rectangular parallelepiped shape.

  The vibrator 54 includes a motor 58 (FIG. 9), a weight 59 (FIG. 8) rotated by the motor 58, and a holder 60 that holds the motor 58.

  The motor 58 is constituted by a rotary motor. Although not specifically shown, the motor 58 includes a field constituting one of the rotor and the stator, an armature constituting the other of the rotor and the stator, a case holding the stator, an output fixed to the rotor and protruding from the case. And a shaft.

  The weight 59 is made of a material having a relatively high density, such as metal, and is fixed to the output shaft of the motor 58 so that the center of gravity is eccentric with respect to the axis of the output shaft of the motor 58. Since the weight 59 is eccentric with respect to the output shaft of the motor 58, when the motor 58 is driven and the weight 59 rotates, vibration occurs.

  The holder 60 is formed of an elastic member such as rubber. Inside the holder 60, a space into which the case of the motor 58 is fitted is formed. The outer peripheral surface of the holder 60 is formed in a shape that can be press-fitted into the second recess 13i. That is, in the first embodiment, the outer peripheral surface of the holder 60 is formed in a rectangular parallelepiped shape having a width that is slightly larger than the width of the second recess 13i (the length in the direction orthogonal to the rotation axis RA). The vibrator 54 is press-fitted into the second recess 13i while elastically deforming the holder 60 with the output shaft parallel to the rotation axis RA.

  The inner lid 55 is formed in a substantially rectangular plate shape with resin, for example. The inner lid 55 may or may not have a size that can completely close the second recess 13i. FIG. 8 illustrates a case where the inner lid 55 is formed in a size that exposes the weight 59 of the vibrator 54.

  The inner lid 55 is engaged with the inner case 13. For example, the inner lid 55 includes a first engagement portion 55a (FIG. 9) provided on the rotation shaft RA side and a second engagement portion 55b (FIG. 8) provided on the opposite side of the rotation shaft RA. Have. The first engaging portion 55 a protrudes outward in the direction along the main body portion of the inner lid 55. The second engaging portion 55 b protrudes in a direction orthogonal to the main body portion of the inner lid 55. A hole is formed in the second engagement portion 55b.

  The inner case 13 is formed with a first engaged portion 13k (FIG. 9) that engages with the first engaging portion 55a. The 1st to-be-engaged part 13k is formed in the inside of the 2nd recessed part 13i by the protrusion part which protrudes in the direction orthogonal to the dent direction of the 2nd recessed part 13i. An engagement recess into which the first engagement portion 55a is inserted is formed on the back side of the second recess 13i of the first engaged portion 13k. The inner case 13 is formed with a second engaged portion (not shown) that engages with the second engaging portion 55b. Similarly to the first engaged portion 13k, the second engaged portion is also formed by a protruding portion that protrudes in a direction orthogonal to the recessed direction of the second recessed portion 13i.

  The inner lid 55 has an engaging recess in which a second engaged portion (not shown) is inserted into the hole of the second engaging portion 55b, and the first engaging portion 55a is adjacent to the first engaged portion 13k. It is attached to the inner case 13 by being inserted into the inner case 13. At this time, the inner lid 55 presses the vibrator 54 (holder 60) in the press-fitting direction of the vibrator 54 into the second recess 13i. The holder 60 is compressed by the bottom surface of the second recess 13 i and the inner lid 55. The reaction force from the vibrator 54 and the force applied to the inner surface of the inner lid 55 due to the vibration of the vibrator 54 are supported by the first engaged portion 13k and a second engaged portion (not shown).

  The outer lid 57 is formed in a generally rectangular plate shape with resin, for example. The outer lid 57 is formed in a size that can completely cover the opening of the second recess 13i.

  The CPU 71 and the memory 73 function as a control unit that performs predetermined calculations based on signals from various units such as the operation unit 7 including the key 35 and executes control of various units such as the image processing unit 79.

  The communication processing unit 75 performs communication with other portable terminal devices and servers via a communication system (telephone network or the Internet) by wireless communication using radio waves. Specifically, the communication processing unit 75 modulates various data such as sound data and image data processed by the CPU 71 and transmits the modulated signal via the antenna 81. The communication processing unit 75 demodulates the signal received via the antenna 81 and outputs the demodulated data to the CPU 71.

  The acoustic processing unit 77 converts the acoustic data from the CPU 71 into an electrical signal, and outputs the signal to the speaker 83 for call or the speaker 85 that outputs a notification sound or the like. The speaker 83 and the speaker 85 convert the electric signal from the sound processing unit 77 into sound and output the sound. On the other hand, the microphone 87 converts the input sound into an electrical signal and outputs the signal to the sound processing unit 77. The acoustic processing unit 77 converts the electrical signal from the microphone 87 into acoustic data, and outputs the acoustic data to the CPU 71.

  The image processing unit 79 converts the image data from the CPU 71 into an image signal and outputs the signal to the display unit 9. In addition, the image processing unit 79 converts the imaging signal (image data) output from the imaging unit 89 into image data of a predetermined format, and outputs the image data to the CPU 71. Note that the imaging unit 89 includes the camera unit 24.

  The motor driver 80 supplies driving power to the motor 58 based on a control signal from the CPU 71. The CPU 71 outputs a control signal to the motor driver 80 in response to, for example, calling a call from another communication terminal or receiving a mail.
