Description

  The present invention relates to an information processing apparatus in which a first main body member and a second main body member are configured to be relatively rotatable.

  There is known an information processing device (for example, a foldable mobile phone device) in which a first main body member and a second main body member are configured to be relatively rotatable around a predetermined rotation axis. The information processing apparatus includes a shaft member that passes through a first shaft member hole formed in the first body member and a second shaft member hole formed in the second body member.

  The shaft member includes a first shaft component member and a second shaft component member configured to be able to rotate relative to each other around the rotation shaft by engaging with each other. The first shaft component member is fixed to the first main body member in a state of being accommodated in the first shaft member hole. The second shaft component member is fixed to the second body member in a state of being accommodated in the second shaft member hole.

The shaft member includes a first shaft component member and a second shaft component member when a rotation angle formed by the first shaft component member and the second shaft component member is within a preset rotation angle range. Is configured to generate a torque for causing relative rotation. For this reason, a hole for accommodating a coil spring or the like is formed in the second shaft component member. The hole is formed so as to open toward the first shaft constituent member side of the second shaft constituent member.
JP 2001-116038 A

  By the way, when the second shaft component member is formed by pressing a flat plate-like member, the outer wall surface parallel to the rotation axis of the second shaft component member has an opening (that is, the first hole). A protruding portion that protrudes outward with respect to the rotating shaft may be formed at an end portion on the side of the one shaft component member. In particular, as the size of the second shaft component member decreases, the processing accuracy decreases, and thus the protrusion is easily formed.

  Therefore, the cross-sectional shape of the hole (the first shaft member hole or the second shaft member hole) in which the second shaft component member is accommodated is not formed in the projecting portion (that is, as designed). When the first main body member and the second main body member are formed so as to have the same shape as the cross-sectional shape of the second shaft constituent member in the case of There is a problem that it cannot be incorporated into the information processing apparatus at a planned (designed) position. If the cross-sectional shape of the hole is increased as a whole in order to cope with this problem, there arises a problem that the shaft member freely moves in the hole (that is, looseness occurs).

  For this reason, the object of the present invention is to solve the above-mentioned problem that “when the protruding portion is formed on the outer wall surface of the shaft member, the shaft member cannot be incorporated at the designed position”. Is to provide a simple information processing apparatus.

In order to achieve such an object, an information processing apparatus according to an aspect of the present invention provides:
A shaft member including a first shaft component member and a second shaft component member configured to be relatively rotatable around a predetermined rotation axis by engaging with each other;
A first shaft member hole in which the first shaft component member is accommodated is formed, and the first shaft component member is accommodated in the first shaft member hole. A first body member to which the constituent members are fixed;
A second shaft member hole in which the second shaft component member is accommodated is formed, and the second shaft member is accommodated in the second shaft member hole. A second body member to which the constituent members are fixed;
And the first main body member and the second main body member are configured to be relatively rotatable about the rotation axis.

  Further, in the first main body member and the second main body member, the inner wall surface forming the first shaft member hole and the second shaft member hole is formed on the second shaft component member. A gap is provided between the inner wall surface and the outer wall surface in a predetermined gap forming region including a position closest to the end on the first shaft component side of the outer wall surface parallel to the rotation axis. Formed as follows.

  According to the present invention configured as described above, the shaft member can be incorporated at the designed position even when the protruding portion is formed on the outer wall surface of the shaft member.

An information processing apparatus according to one aspect of the present invention
A shaft member including a first shaft component member and a second shaft component member configured to be relatively rotatable around a predetermined rotation axis by engaging with each other;
A first shaft member hole in which the first shaft component member is accommodated is formed, and the first shaft component member is accommodated in the first shaft member hole. A first body member to which the constituent members are fixed;
A second shaft member hole in which the second shaft component member is accommodated is formed, and the second shaft member is accommodated in the second shaft member hole. A second body member to which the constituent members are fixed;
And the first main body member and the second main body member are configured to be relatively rotatable about the rotation axis.

  Further, in the first main body member and the second main body member, the inner wall surface forming the first shaft member hole and the second shaft member hole is formed on the second shaft component member. A gap is provided between the inner wall surface and the outer wall surface in a predetermined gap forming region including a position closest to the end on the first shaft component side of the outer wall surface parallel to the rotation axis. Formed as follows.

  According to this, even when the protruding portion is formed at the end portion on the first shaft component side of the outer wall surface of the second shaft component member, the first shaft member hole and the second shaft member are formed. It is possible to avoid contact between the inner wall surface forming the shaft member hole and the protruding portion. As a result, the shaft member in which the protruding portion is formed on the outer wall surface of the second shaft component member can be incorporated into the information processing apparatus at the planned (designed) position.

in this case,
In the second body member, the gap forming region is a direction along the rotation axis of the inner wall surface forming the second shaft member hole, and the second body member is separated from the second shaft component member. Formed so as to include a region from the end on the first direction side toward the first shaft component to a position away from the end of the first direction by a predetermined gap forming region length toward the second direction opposite to the first direction. It is preferred that

  According to this, even when the protruding portion is formed at the end portion on the first direction side of the outer wall surface of the second shaft component member, the first main body member side (that is, the shaft member is The shaft member is inserted into the second shaft member hole by moving the shaft member in the second direction by the length of the second shaft component in the direction along the rotation axis plus the gap forming region length. can do.

  Thus, for example, in the state where the first shaft member hole and the second shaft member hole are coaxially opposed to each other when the information processing apparatus is assembled, the first body member and the second body member The shaft member can be incorporated into the information processing apparatus even if the length of the relative movement in the direction along the rotation axis is relatively short. Specifically, after the shaft member is inserted into the second shaft member hole from the first body member side, the first shaft member hole and the second shaft member hole are coaxially opposed to each other. The first body member and the second body member are arranged as described above, and then the shaft member is moved in the second direction, whereby the shaft member (the first shaft component member) is moved to the first shaft member. Can be inserted into the service hole.

in this case,
The second main body member has a gap forming region length from an end portion on the first direction side of the second shaft constituent member to an end portion on the first direction side of the shaft member. It is preferable that the length is longer than the length in the first direction.

  According to this, when the shaft member is inserted into the second shaft member hole from the first main body member side, the end of the shaft member on the first direction side is the opening of the second shaft member hole. Can be located in a plane formed by the. Therefore, when the information processing apparatus is assembled, the first main body member and the second main body member are rotated about the rotation shaft in a state where the first shaft member hole and the second shaft member hole are coaxially opposed to each other. The shaft member can be incorporated into the information processing apparatus even if the length that can be relatively moved in the direction along the axis is extremely short.

in this case,
In the second main body member, the inner wall surface forming the second shaft member hole is opposite to the first shaft component member of the outer wall surfaces parallel to the rotation axis of the second shaft component member. Formed to contact the side edge,
In the second shaft component member, an end portion of the outer wall surface parallel to the rotation axis on the side opposite to the first shaft component member is in contact with the inner wall surface forming the second shaft member hole. By doing so, it is preferable to be configured to be fixed to the second main body member.

  According to this, the edge part on the opposite side to the 1st axis | shaft component member among the outer wall surfaces of a 2nd axis | shaft component member, and the inner wall surface which forms the hole for 2nd axis members contact. Thereby, the second shaft component member is fixed to the second main body member. Accordingly, it is possible to prevent the second shaft component member from freely moving in the second shaft member hole. That is, the second shaft component member can be reliably fixed to the second main body member.

In another aspect of the information processing apparatus,
The second main body member is formed so that the gap forming region includes all the region of the inner wall surface forming the second shaft member hole,
It is preferable to provide a fixing member that fixes an end of the second shaft component member opposite to the first shaft component member to the second body member.

  According to this, when assembling the information processing apparatus, the first main body member and the second main body member are arranged so that the first shaft member hole and the second shaft member hole are coaxially opposed to each other. In the state where the shaft member is disposed, the shaft member is inserted into the second shaft member hole from the end opposite to the first shaft member hole of the second shaft member hole, and the shaft member is further inserted into the second shaft member. By moving in a direction from the member hole toward the first shaft member hole, the shaft member (the first shaft component member) can be inserted into the first shaft member hole. Thereafter, the second shaft component member can be fixed to the second main body member by the fixing member. That is, according to the above configuration, the shaft member can be easily incorporated into the information processing apparatus.

in this case,
The shaft member is a first shaft component when the rotation angle around the rotation axis formed by the first shaft component and the second shaft component is within a preset rotation angle range. And the second shaft constituent member are preferably configured to generate a torque that causes relative rotation about the rotation axis.

in this case,

  Hereinafter, embodiments of an information processing apparatus according to the present invention will be described with reference to FIGS.

<First Embodiment>
As shown in FIG. 1 which is an exploded view of a part of a casing constituting the mobile phone device 1, the mobile phone device 1 as an information processing apparatus according to the first embodiment has a first casing (first Main body member) 10, second housing (second main body member) 20, and shaft member (hinge unit) 30.

  FIG. 2 is a view of the mobile phone device 1 as viewed from the back in a state where the first housing 10, the second housing 20, and the shaft member 30 are incorporated in the mobile phone device 1. Hereinafter, the description will be continued using a right-handed orthogonal coordinate system including the X axis, the Y axis, and the Z axis.

  FIG. 3 is a diagram of the mobile phone device 1 viewed from the front in a state where the first housing 10, the second housing 20, and the shaft member 30 are incorporated in the mobile phone device 1. 4 is a cross-sectional view of the cellular phone device 1 taken along a plane including line 4-4 of FIGS. 2 and 3 and perpendicular to the X axis.

  As illustrated in FIGS. 1 to 5, the shaft member 30 is a columnar member that extends along the Y axis (rotary axis). That is, the outer wall surface parallel to the Y axis of the shaft member 30 constitutes the outer peripheral surface of the column that extends along the Y axis.

  The shape of the cross section obtained by cutting the outer wall surface parallel to the Y-axis of the shaft member 30 with a plane orthogonal to the Y-axis is a substantially rectangular shape that is curved so that the short side protrudes outward. As shown in FIG. 5A, the shaft member 30 includes a first shaft component member 31 and a second shaft component member 32 that are disposed adjacent to each other in the direction along the Y axis.

  Furthermore, as shown in FIG. 5B, which is a cross-sectional view of the shaft member 30 taken along a plane orthogonal to the X axis, the shaft member 30 includes a cam member 33, a shaft member 34, a compression coil spring 35, and the like. .

The first shaft constituent member 31 constitutes a portion of the shaft member 30 on the Y axis positive direction side.
The second shaft component member 32 is a member formed by pressing a flat plate member (steel plate) made of metal (in this example, steel). The second shaft constituting member 32 constitutes a portion of the shaft member 30 on the Y axis negative direction side. The second shaft component member 32 is formed with a cam member accommodation hole RH1 that opens toward the positive Y-axis direction (the first shaft component member 31 side). The cam member accommodation hole RH1 is a cylindrical space.

  The end of the first shaft component member 31 on the Y axis negative direction side has a columnar shape with a smaller diameter than the cam member accommodation hole RH1. The end of the first shaft component member 31 on the Y axis negative direction side is accommodated in the cam member accommodation hole RH1. The first shaft component member 31 is formed with a cam hole CH1 that opens in the negative Y-axis direction. The cam hole CH1 is a cylindrical space.

  Further, on the outer wall surface on the Y axis negative direction side of the portion constituting the outer periphery of the cam hole CH1 in the first shaft component member 31 (the end surface on the Y axis negative direction side of the first shaft component member 31). A cam surface CS1 is formed. That is, the outer wall surface CS1 on the Y axis negative direction side of the portion constituting the outer periphery of the cam hole CH1 in the first shaft constituent member 31 has a different position in the Y axis direction according to the rotation angle around the Y axis. It is formed as follows.

  The cam member 33 is a columnar member having substantially the same diameter as the cam member accommodation hole RH1. The cam member 33 is accommodated in the cam member accommodation hole RH1. The cam member 33 is disposed adjacent to the first shaft component member 31 on the Y axis negative direction side of the first shaft component member 31 in the cam member accommodation hole RH1. The cam member 33 is formed with a cam hole CH2 that opens in the positive Y-axis direction. The cam hole CH2 is a cylindrical space having the same diameter as the cam hole CH1.

  Further, a cam surface CS2 is formed on the outer wall surface on the Y-axis positive direction side (the end surface on the Y-axis positive direction side of the cam member 33) of the portion constituting the outer periphery of the cam hole CH2 in the cam member 33. Yes. That is, the outer wall surface CS2 on the Y-axis positive direction side of the portion constituting the outer periphery of the cam hole CH2 in the cam member 33 is formed so that the position in the Y-axis direction differs according to the rotation angle around the Y-axis. ing.

  A guide groove (concave portion) 32a extending along the Y axis is formed on the inner wall surface of the second shaft component member 32 forming the cam member accommodation hole RH1. Further, a convex portion that is accommodated in the guide groove 32 a is formed on the outer wall surface parallel to the Y axis of the cam member 33. Thus, the cam member 33 is configured to be movable in the cam member accommodation hole RH1 in the Y-axis direction, and is configured to be non-rotatable with respect to the second shaft component member 32.

  The shaft member 34 is a columnar member. The shaft member 34 passes through the first shaft component member 31, the second shaft component member 32, and the cam member 33 so as to pass through the center in a cross section obtained by cutting the shaft member 30 by a plane orthogonal to the Y axis. The shaft member 34 extends along the Y axis. Each of the first shaft component member 31, the second shaft component member 32, and the cam member 33 is rotatable with respect to the shaft member 34. That is, the first shaft constituent member 31 and the second shaft constituent member 32 are capable of relative rotation about the Y axis (rotary axis).

  The compression coil spring 35 is disposed so as to surround the shaft member 34 between the bottom surface of the cam member accommodation hole RH1 and the outer wall surface on the Y axis negative direction side of the cam member 33. The compression coil spring 35 biases the cam member 33 toward the Y axis positive direction. Thereby, the cam surface CS2 of the cam member 33 and the cam surface CS1 of the first shaft constituting member 31 come into contact with each other. That is, the first shaft constituent member 31 is engaged with the second shaft constituent member 32 via the cam member 33.

  With such a configuration, when the first shaft constituent member 31 and the cam member 33 (that is, the second shaft constituent member 32) rotate relative to each other around the Y axis, the cam surface CS1 and the cam surface CS2 come into contact with each other. Changes. As a result, since the position of the cam member 33 in the Y-axis direction changes, the force by which the compression coil spring 35 pushes the cam member 33 in the Y-axis positive direction changes due to the change in the degree to which the compression coil spring 35 is compressed. Thereby, the shaft member 30 has the first shaft configuration when the rotation angle around the Y axis formed by the first shaft configuration member 31 and the second shaft configuration member 32 is in a preset rotation angle range. Torque is generated to try to relatively rotate the member 31 and the second shaft component member 32 about the Y axis.

  As shown in FIG. 4, the first housing 10 is formed with a first shaft member hole HS <b> 1 that opens in the negative Y-axis direction. The inner wall surface 11 that forms the first shaft member hole HS1 includes a first inner wall surface 11a, a second inner wall surface 11b, and a third inner wall surface 11c.

  The first inner wall surface 11 a is the most Y-axis negative direction side portion of the inner wall surface 11. In the first casing 10, the position of the first inner wall surface 11 a is parallel to the Y axis of the second shaft constituent members 32 in a cross section obtained by cutting the mobile phone device 1 along a plane orthogonal to the Y axis. It is formed so as to be positioned on the outer side with respect to the Y axis by the gap length L3 from the position of the outer wall surface.

  The second inner wall surface 11 b is a portion adjacent to the first inner wall surface 11 a on the Y axis positive direction side with respect to the first inner wall surface 11 a of the inner wall surface 11. In the first casing 10, the position of the second inner wall surface 11 b is parallel to the Y axis of the first shaft component 31 in a cross section obtained by cutting the mobile phone device 1 along a plane orthogonal to the Y axis. It is formed so as to be located at substantially the same position as the position of the outer wall surface.

  The third inner wall surface 11c is a portion adjacent to the second inner wall surface 11b on the Y axis positive direction side with respect to the second inner wall surface 11b of the inner wall surface 11 (that is, the portion closest to the Y axis positive direction side). It is. In the first casing 10, the position of the third inner wall surface 11 c is parallel to the Y axis of the first shaft constituent members 31 in a cross section obtained by cutting the mobile phone device 1 along a plane orthogonal to the Y axis. It is formed so as to be located on the inner side with respect to the Y axis by a predetermined length from the position of the outer wall surface.

  With such a configuration, in a state where the first shaft component member 31 is accommodated in the first shaft member hole HS1, the second inner wall surface 11b and the first shaft component member 31 are parallel to the Y axis. The first shaft component 31 is fixed to the first housing 10 so as not to rotate by contacting the wall surface.

In addition, the second housing 20 is formed with a second shaft member hole HS2 that opens toward the positive Y-axis direction. The second casing 20 is arranged such that the first shaft member hole HS1 and the second shaft member hole HS2 are coaxially opposed to each other.
The inner wall surface 21 that forms the second shaft member hole HS2 includes a first inner wall surface 21a and a second inner wall surface 21b.

  The first inner wall surface 21a is a gap forming region from the end of the inner wall surface 21 on the Y-axis positive direction (the first direction that is the direction from the second shaft component member 32 toward the first shaft component member 31). This is a portion up to a position separated by a length L2 toward the Y-axis negative direction (second direction opposite to the first direction). The gap forming region length L2 is from the end of the second shaft component member 32 on the Y axis positive direction (first direction) side to the Y axis positive direction (first direction) side of the shaft member 30. It is longer than the length L1 in the Y-axis direction to the end.

  In the second casing 20, the position of the first inner wall surface 21 a is parallel to the Y axis of the second shaft constituent members 32 in a cross section obtained by cutting the mobile phone device 1 along a plane orthogonal to the Y axis. It is formed so as to be positioned on the outer side with respect to the Y axis by the gap length L3 from the position of the outer wall surface.

  The second inner wall surface 21 b is a portion of the inner wall surface 21 on the Y axis negative direction side with respect to the first inner wall surface 21 a. In the second casing 20, the position of the second inner wall surface 21 b is parallel to the Y axis of the second shaft constituent members 32 in a cross section obtained by cutting the mobile phone device 1 along a plane orthogonal to the Y axis. It is formed so as to be located at substantially the same position as the position of the outer wall surface.

  With such a configuration, in a state where the second shaft component member 32 is accommodated in the second shaft member hole HS2, the second inner wall surface 21b and the second shaft component member 32 are parallel to the Y axis. The second shaft component member 32 is fixed to the second housing 20 so as not to rotate by contacting the end of the wall surface on the Y axis negative direction side.

  According to the above configuration, the first casing 10 and the second casing 20 can be relatively rotated about the Y axis (rotating axis).

  Furthermore, according to the first embodiment, as shown in FIG. 4, the inner wall surfaces 11 and 21 that form the first shaft member hole HS1 and the second shaft member hole HS2 in the gap forming region R1. And a gap between the second shaft component member 32 and the outer wall surface parallel to the Y axis. In the gap forming region R1, the inner wall surfaces 11 and 21 are located at the end of the outer wall surface parallel to the Y axis of the second shaft component member 32 on the Y axis positive direction (first shaft component member 31) side most. It is an area including a close position.

  Therefore, even if the protrusion 32b is formed at the end of the outer wall surface of the second shaft constituent member 32 on the Y axis positive direction (first shaft constituent member 31) side, the first shaft It is possible to avoid contact between the inner wall surfaces 11 and 21 forming the member hole HS1 and the second shaft member hole HS2 and the protruding portion 32b. As a result, the shaft member 30 in which the protrusion 32b is formed on the outer wall surface of the second shaft component member 32 can be incorporated into the mobile phone device 1 at a planned (designed) position.

  Furthermore, according to the first embodiment, even when the protruding portion 32b is formed at the end on the Y axis positive direction side of the outer wall surface of the second shaft component member 32, the first housing. From the body 10 side (that is, by moving the shaft member 30 in the negative Y-axis direction), the gap member region length L2 is set to the length of the second shaft component member 32 in the direction along the Y-axis. Can be inserted into the second shaft member hole HS <b> 2 by the length added.

  Thus, when the cellular phone device 1 is assembled, the first casing 10 and the second casing are arranged in a state where the first shaft member hole HS1 and the second shaft member hole HS2 are coaxially opposed to each other. The shaft member 30 can be incorporated into the mobile phone device 1 even when the length of the relative movement of the body 20 in the direction along the Y axis is relatively short.

  Specifically, first, as shown in FIG. 6A, the shaft member 30 is disposed on the Y axis positive direction side with respect to the second shaft member hole HS2. Then, by moving the shaft member 30 in the Y-axis negative direction (the direction of the arrow AR1), the shaft member 30 is inserted into the second shaft member hole HS2 from the Y-axis positive direction side.

  By the way, in the said 1st Embodiment, the clearance gap formation area length L2 is the axis | shaft member 30 from the edge part (namely, protrusion part 32b) of the Y-axis positive direction side among the 2nd shaft structural members 32. Is longer than the length L1 in the Y-axis direction up to the end on the Y-axis positive direction side.

  Therefore, as shown in FIG. 6B, when the shaft member 30 is inserted into the second shaft member hole HS2 from the Y-axis positive direction side, the end portion of the shaft member 30 on the Y-axis positive direction side Can be positioned in a plane formed by the opening of the second shaft member hole HS2. Therefore, when the mobile phone device 1 is assembled, the first casing 10 and the second casing are arranged in a state where the first shaft member hole HS1 and the second shaft member hole HS2 are coaxially opposed to each other. As will be described later, the shaft member 30 can be incorporated into the mobile phone device 1 even when the length that can be relatively moved in the direction along the Y axis is extremely short.

  Next, as shown in FIG. 6C, the first housing 10 is arranged so that the first shaft member hole HS1 and the second shaft member hole HS2 are coaxially opposed to each other. The second housing 20 is arranged. Thereafter, the shaft member 30 (the first shaft component member 31) can be inserted into the first shaft member hole HS1 by moving the shaft member 30 in the positive Y-axis direction (that is, in the direction of the arrow AR2). it can.

  In this manner, the first shaft component member 31 is fixed to the first housing 10 in a state where the first shaft component member 31 is accommodated in the first shaft member hole HS1, and the second The second shaft constituent member 32 can be fixed to the second housing 20 in a state where the shaft constituent member 32 is accommodated in the second shaft member hole HS2. That is, the first housing 10, the second housing 20, and the shaft member 30 can be incorporated into the mobile phone device 1.

  Further, according to the first embodiment, the end of the outer wall surface of the second shaft component member 32 on the Y axis negative direction side (the side opposite to the first shaft component member 31), and the second shaft The inner wall surface 21b forming the member hole HS2 comes into contact. Thereby, the second shaft constituent member 32 is fixed to the second casing 20. Therefore, it is possible to prevent the second shaft component member 32 from freely moving in the second shaft member hole HS2. That is, the second shaft component member 32 can be securely fixed to the second housing 20.

  In addition, according to the first embodiment, a hole that opens at the outer wall surface (design surface) on the Y axis positive direction side of the first housing 10 is formed, and the shaft member 30 is formed via the hole. The shaft member 30 can be incorporated into the mobile phone device 1 without being inserted. Therefore, as shown in FIG. 7, it is possible to avoid the formation of a hole that opens in the outer wall surface of the first housing 10 on the Y axis positive direction side.

The inner wall surface 21 that forms the second shaft member hole HS2 includes a first inner wall surface 21a and a third inner wall surface 21c.

  The first inner wall surface 21a is separated from the end on the Y axis positive direction side of the inner wall surface 21 toward the Y axis negative direction side by a length shorter than the length of the second shaft component member 32 in the Y axis direction. The part up to the position. In the second casing 20, the position of the first inner wall surface 21 a is parallel to the Y axis of the second shaft constituent members 32 in a cross section obtained by cutting the mobile phone device 1 along a plane orthogonal to the Y axis. It is formed so as to be positioned on the outer side with respect to the Y axis by the gap length L3 from the position of the outer wall surface.

  The third inner wall surface 21 c is a portion on the Y axis negative direction side of the inner wall surface 21 with respect to the first inner wall surface 21 a. In the second casing 20, the position of the third inner wall surface 21 c is parallel to the Y axis of the second shaft constituent members 32 in a cross section obtained by cutting the mobile phone device 1 along a plane orthogonal to the Y axis. It is formed so as to be located on the outer side with respect to the Y axis by a length longer than the gap length L3 from the position of the outer wall surface.
