However, in the drawings, the dimensions, ratios, and the like of each part may not be shown so as to completely match the actual ones. Further, details may be omitted depending on the drawings.

  FIG. 1 is an external view of a mobile phone 1 of this embodiment which is an example of an electronic device. 1A is a front view and FIG. 1B is a side view. 2A and 2B are perspective views showing an external appearance of the mobile phone 1, FIG. 2A is a perspective view seen from the front side, and FIG. 2B is a perspective view seen from the back side. Note that in this specification, the up, down, left, and right directions of the mobile phone 1 are the directions shown in FIGS. 1 (A) and 2 (A).

  First, the outline of the first case 30 and the second case 50 included in the mobile phone 1 and the mobile phone 1 will be described, and further, the separation operation of the first case 30 and the second case 50 will be described. The combination operation will be described in detail.

  The mobile phone 1 has a first housing 30 and a second housing 50. The first housing 30 and the second housing 50 can be coupled to each other by an attractive action by magnetic force. 1 and 2, the first casing 30 and the second casing 50 are brought into contact with each other by bringing the bottom of the first casing 30 into contact with the upper edge of the second casing 50. The combined state is shown. As is apparent from FIG. 1B, the first housing 30 and the second housing 50 have a bent appearance at the time of coupling.

  Such a cellular phone 1 can be separated into a first casing 30 and a second casing 50 as shown in FIG. The separated first housing 30 is on the side of the mobile phone 1 and the second housing 50 is on the side of the base phone of the mobile phone 1. As will be described later in detail, the first housing 30 has a power switch 32 disposed on the right side surface so that the operation unit is exposed. The second casing 50 has a volume key 57 arranged on the side surface so that the operation unit is exposed.

  FIG. 4 is an explanatory view schematically showing the arrangement of members of the mobile phone 1. 5 is a cross-sectional view taken along line AA in FIG. 1B, and FIG. 5A shows a state where the first housing 30 and the second housing 50 are separated. FIG. 5B shows a state where the first casing 30 and the second casing 50 are coupled.

  The first housing 30 includes a first member 40 and a second member 41, both of which are ferromagnetic materials. Two second members 41 are provided and arranged on the left and right sides of the lower end of the first housing 30, respectively. In such a direction that the second member 41 is separated from the second housing 50 such that the second member 41 is located closer to the center of the first housing 30 than the first member 40. They are staggered. Here, the direction in which the first housing 40 is separated from the second housing 50 substantially coincides with the vertical direction shown in FIG.

  The first housing 30 has a space 45 into which a later-described fourth member 62 is inserted. The space 45 is open to the outside of the housing at the lower edge of the first housing 30, and the second member 41 is disposed on the back side of the space 45. On the other hand, the first member 40 is disposed along the lower end edge of the first housing 30. Thus, the 1st member 40 and the 2nd member 41 are shifted and arranged.

The second housing 50 includes a third member 61 that is attracted to the first member 40 by a magnetic force. The third member 61 is an iron plate that is a magnetic body.
The second housing 50 is further attracted to the second member 41 by a magnetic attraction action, and is provided so as to be movable from the second housing 50 toward the second member 41. The member 62 is provided. FIG. 6 is an explanatory view showing a part of the second casing 50 by cutting away the inside thereof, and shows the surroundings where the fourth member 62 is arranged. The fourth member 62 shown in FIG. 6 is housed in the second housing 50.
FIG. 7 is an explanatory view showing the interior of each of the first housing 30 and the second housing 50 in a coupled state, with the second member 41 and the fourth member 62 broken away. Indicates the surrounding area. The fourth member 62 shown in FIG. 7 is in a state of moving from the inside of the second housing 50 toward the second member 41.

The fourth member 62 is made of iron, which is a magnetic body, and has a pin shape. More specifically, it has a shape including a small diameter portion 621 on the distal end side and a large diameter portion 622 on the proximal end side. The fourth member 62 can go in and out of the second housing 50 through the hole 50 a provided in the second housing 50. Two such fourth members 62 are provided corresponding to the second member 41.
The operation of the fourth member 62 in and out will be described with reference to FIG. FIG. 8A shows a state where the fourth member 62 is accommodated in the second housing 50. FIG. 8B shows a state in which the fourth member 62 has moved toward the second member 41. When the lower end edge of the first casing 30 is brought close to the upper end edge of the second casing 50 in a state where the fourth member 62 is accommodated as shown in FIG. 8A, the fourth member 62 is It is attracted to the second member 41 by the magnetic force. Then, the fourth member 62 moves so as to be pulled out from the second housing 50 as shown in FIG. 8B and further enters the space 45. At this time, the fourth member 62 moves to a position where the large diameter portion 622 abuts on the inner peripheral surface 501 of the upper end wall of the second casing 50.
As described above, the fourth member 62 is accommodated in the second housing 50 when not receiving the suction action between the second member 41 and the suction action between the fourth member 62 and the second member 41. It moves, is pulled out to the outside, and further enters the space 45.
At this time, the first member 40 and the third member 61 are also attracted to each other by magnetic force, and the first housing 30 and the second housing 50 are coupled.

  The second housing 50 further includes a spring member 62 a that urges the fourth member 62 in a direction to move the fourth member 62 toward the center of the second housing 50. The spring member 62 a returns the fourth member 62 that has not been attracted to the second member 41 by the magnetic force to the second housing 50. As a result, the fourth member 62 is housed again in the second housing 50. The spring member 62a is an example of an elastic body, and can be replaced with another member that can bias the fourth member 41 in the direction in which the fourth member 41 is moved toward the center of the second housing 50.

As described above, the direction in which the first housing 40 is separated from the second housing 50 so that the second member 41 is positioned closer to the center of the first housing 30 than the first member 40 is. It is arranged to shift to. Here, the displacement in the arrangement of the first member 40 and the second member 41 is associated with the amount of movement of the fourth member 62 when sucked by the second member 41. That is, as shown in FIGS. 4 and 5, the displacement S in the arrangement of the first member 40 and the second member 41 is related to the movement amount S of the fourth member 62. The displacement S in the arrangement and the movement amount S of the fourth member 62 are reflected in the depth S of the space 45 as shown in FIG. As a result, the fourth member 62 can penetrate deeply into the space 45. Further, the large diameter portion 622 of the fourth member 62 comes into contact with the inner peripheral surface 501 of the upper end wall of the second housing 50 and is stabilized. As a result, a stable coupling state between the first housing 30 and the second housing 50 can be obtained. That is, in addition to the suction action between the first member 40 and the third member 61, a strong coupled state can be achieved by the suction action between the second member 41 and the fourth member 62. Furthermore, when the pin-shaped fourth member 62 enters the space 45 of the first housing 30, it is possible to prevent the two housings 30 and 50 from being displaced and rattling. By providing two fourth members 62, relative rotation of the two casings 30 and 50 is also suppressed.
Note that when the large-diameter portion 622 of the fourth member 62 is in contact with the inner peripheral surface 501 of the upper end wall of the second casing 50, the tip of the fourth member 62 collides with the second member 41. The dimension S is set so as not to occur.

  As described above, the mobile phone 1 can set the first housing 30 and the second housing 50 in the combined state shown in FIGS. 1 and 2 and the separated state shown in FIG. In addition to these two states, the mobile phone 1 can be in a state in which the first housing 30 and the second housing 50 are overlapped as shown in FIG. The mobile phone 1 has a fifth member 43, a sixth member 44, a seventh member 63, an eighth member in order to make the first housing 30 and the second housing 50 overlap with each other. The member 64 is provided.

  The arrangement of these members will be described with reference to FIG. First, the fifth member 43 made of a ferromagnetic material is first provided in the housing 30. The fifth member 43 is disposed so as to be offset upward and to the right of the center of the first housing 30. In addition, two sixth members 44 made of a ferromagnetic material are provided, and are respectively disposed on the left and right sides of the lower end of the first housing 30. The sixth member 44 is disposed on the back side of the second member 41 as shown in FIG. As described above, the first housing 30 has three members for bringing the first housing 30 and the second housing 50 into a superimposed state.

On the other hand, the seventh member 63 and the eighth member 64 that are both magnetic bodies and are made of iron plates are disposed in the second housing 50. The seventh suction member 63 is disposed at a position corresponding to the position of the fifth member 43 when the first housing 30 and the second housing 50 are overlapped. Further, the eighth member 64 is disposed at a position corresponding to the position of the sixth member 44 when the first housing 30 and the second housing 50 are overlapped. Here, the direction in which the first casing 30 and the second casing 50 are overlapped is such that the right side where the operation unit of the power switch 32 is exposed and the right side where the volume key 57 is exposed are positioned on the same side. It is assumed that they are superimposed on each other.
As described above, the second casing 50 has three members for bringing the first casing 30 and the second casing 50 into a superimposed state.

As described above, since the first casing 30 and the second casing 50 include members at three points, the first casing 30 and the second casing 50 can be superposed in a single direction. Determined. That is, by arranging the members asymmetrically in the upper and lower directions in each case, the direction of superposition of the first case 30 and the second case 50 is determined in a single way. If the first housing 30 and the second housing 50 are overlapped with each other by rotating 180 ° from the temporarily determined direction, the position of the member is shifted, so that it is not possible to enjoy the attracting action by magnetic force. As a result, the first casing 30 and the second casing 50 are not fixed in a state where they are overlapped.
If the first housing 30 and the second housing 50 are overlapped and fixed in a state where the first housing 30 and the second housing 50 are rotated 180 degrees from a predetermined direction, the following inconveniences can be considered. That is, the power switch 32 provided so that the operation unit is exposed on the right side surface of the first housing 30 and the volume key 57 provided so that the operation unit is exposed on the right side surface of the second housing 50. Are located on different sides, which is inconvenient. If it is made to receive a suction action when it overlaps with the direction defined as mentioned above, it will be released from such inconvenience.

  As described above, the cellular phone 1 according to the present embodiment includes a large number of members in order to obtain a combined state as shown in FIGS. 1 and 2 and an overlapped state as shown in FIG. Here, the combination of each member is arranged.

  The combination of the first member 40 and the third member 61 attracts each other by magnetic force. The combination of the second member 41 and the fourth member 62 attracts each other by magnetic force. A combination of the fifth member 43 and the seventh member 64 attracts each other by magnetic force. The combination of the sixth member 44 and the eighth member 63 attracts each other by magnetic force.

  Any one of the members in the above combination may be a ferromagnetic material and the other may be a ferromagnetic material or a magnetic material that is attracted to the ferromagnetic material by a magnetic force. That is, a combination of a permanent magnet, one of which is a ferromagnetic material, and iron, the other, which is a magnetic material.

As shown in FIGS. 1 and 2, the mobile phone 1 can couple and separate the first housing 30 and the second housing 50. Further, as shown in FIG. 10, the first casing 30 and the second casing 50 may be overlapped. The mobile phone 1 can be used in any of these three modes.
The mobile phone 1 has various functional components mounted inside the first casing 30 and the second casing 50 so that any of these three modes can be used.

As described above, the second electric circuit 65 is formed inside the second casing 50.

In the mobile phone 1 as described above, each member for connecting the first housing 30 and the second housing 50 is housed in each housing, so that adhesion of iron sand or the like is suppressed and magnetic force is applied. A decrease in suction force can be suppressed. Thereby, the stable coupling | bonding state of the 1st housing | casing 30 and the 2nd housing | casing 50 can be obtained.
Further, the fourth member 62 acts as a positioning between the first housing 30 and the second housing 50, thereby preventing the two housings 30 and 50 from being displaced and rattling.
Further, when separating the first casing 30 and the second casing, the first casing 30 and the second casing 50 may be simply separated, and the buttons and nails are operated. No special operation is required.

  Further, such a fourth member 62 is difficult to see from the outside when the two casings 30 and 50 are separated and combined, and has little influence on the appearance of the mobile phone 1. For this reason, the cellular phone 1 can obtain a good appearance design with few irregularities in either the state where the first casing 30 and the second casing 50 are coupled or the separated state.

Next, Example 2 will be described with reference to FIGS. 11 and 12.
Example 2 is different from Example 1 in the following points.
First, in the second embodiment, the first contact spring 42 is disposed in the first housing 30 and the second contact spring 66 is disposed in the second housing 50. And different. The first contact spring 42 and the second contact spring 66 are connected to the first electrical circuit 46 disposed in the first housing 30 and the second housing as the fourth member 62 moves. This corresponds to switch means for connecting and disconnecting electrical continuity with the second electrical circuit 65 disposed in the circuit 50.

  The second embodiment is different from the first embodiment in that an interface connector 67 is provided instead of the USB connector 56 in the first embodiment. That is, the second electric circuit 65 includes an interface connector 67 corresponding to a second connector for charging the battery pack 58. The interface connector 65 is a different type of connector from the USB connector 36 for charging the battery pack 37 included in the first electric circuit 46.

  Hereinafter, differences from the first embodiment will be described. Since other configurations are not different from those of the first embodiment, common components are denoted by the same reference numerals in the drawings, and detailed description thereof is omitted.

  First, the arrangement of the first contact spring 42 and the second contact spring 66 will be described with reference to FIG. FIG. 12 is a drawing corresponding to FIG. 8 in the first embodiment, and FIG. 12A shows a state in which the fourth member 62 is accommodated in the second housing 50.
