[0008] (Background to this disclosure) Electronic devices with multiple connected housings come in a variety of shapes. For example, some electronic devices have a cavity formed in the center of the width direction at the front end. The cavity is formed for the purpose of accommodating, for example, a battery. In such electronic devices, some of the multiple housings have a recess formed by cutting away a portion corresponding to the cavity from the front end toward the back. As a result, some of the housings have narrow portions on both sides of the recess that protrude from the back toward the front.

[0009] When a housing having a narrow portion is molded, the narrow portion may be deformed toward the recess due to thermal contraction. If such deformation occurs, when the housing having the narrow portion is connected to another housing, the relative positional misalignment between the narrow portion and the other housing may make the connection difficult.

[0010] One possible solution to the above-mentioned deformation of the narrow portion is to provide a plate-like rib on the housing that is to be connected to the other housing having the narrow portion. The rib is provided in a position adjacent to the narrow portion when not deformed. When the housing having the narrow portion is connected to the other housing, the connection is made while forcibly returning the deformed narrow portion to its original position before deformation. The narrow portion that has been forcibly returned to its original position attempts to return to the deformed position due to elastic force. The deformation of the narrow portion due to elastic force is restricted by the rib.

[0011] However, because the strength of the plate-like ribs is weak, if the elastic force of the narrow portion is strong, there is a risk that the ribs may bend or crack, resulting in damage to the ribs.

[0012] Therefore, the inventors discovered that by connecting the narrow portion to another housing via a boss portion and a receiving portion into which the boss portion is inserted, the strength of the connecting portion between the narrow portion and another housing can be increased, thereby reducing the possibility of the housing being damaged by the elastic force of the narrow portion, and have come to the following disclosure.

[0013] (Embodiment 1) [Overall configuration] FIG. 1 is a perspective view of an example of an electronic device according to an embodiment of the present disclosure, as viewed from above. FIG. 2 is a perspective view of an example of an electronic device according to an embodiment of the present disclosure, as viewed from below. The X, Y, and Z directions in the figure represent the width, depth, and height directions of the housing 2, respectively. The X, Y, and Z directions are orthogonal to each other. In this specification, for convenience of explanation, in the Y direction, the side where the hinge unit 7 is provided is referred to as the rear side, and the side where the touchpad 5 is provided is referred to as the front side. That is, the direction of the arrow indicating the Y direction in the figure is the rear direction, and the direction opposite to the arrow is the front direction. Also, in the X direction, the right and left sides are defined when viewing the electronic device 1 from the front. That is, the direction of the arrow indicating the X direction in the figure is the right direction, and the direction opposite to the arrow is the left direction. Also, in the Z direction, the side where the keyboard 4 and the touchpad 5 are exposed is referred to as the upper side, and the side where the cover unit 81 is provided is referred to as the lower side. That is, the direction of the arrow indicating the Z direction in the figure is the upward direction, and the direction opposite to the arrow is the downward direction. The X direction is an example of a second direction. The Y direction is an example of a first direction, and the Z direction is an example of an opposing direction.

[0014] In this embodiment, the electronic device 1 is a notebook-type personal computer (laptop PC), as shown in FIGS.

[0015] The electronic device 1 includes a housing 2 and a housing 3. The housings 2 and 3 each have a thin, box-like outer shell and are rectangular when viewed from above.

[0016] The housing 2 houses a keyboard 4 and a touchpad 5. The housing 3 houses a liquid crystal panel 6. In this specification, the keyboard 4 and the touchpad 5 may be referred to as input units 4, 5, and the liquid crystal panel 6 may be referred to as a display unit 6.

[0017] The housings 2 and 3 are connected via a hinge unit 7. The hinge unit 7 is provided at the end of the housing 2 in the depth direction (Y direction), i.e., at the rear end of the housing 2. The hinge unit 7 rotatably connects the housings 2 and 3. The hinge unit 7 allows at least one of the housings 2 and 3 to rotate, allowing the electronic device 1 to be opened and closed. Specifically, the hinge unit 7 allows the electronic device 1 to be placed in an open state and a closed state. The "open state" refers to a state in which the housings 2 and 3 are separated from each other, exposing the input units 4 and 5 and the display unit 6. The "closed state" refers to a state in which the housings 2 and 3 are arranged opposite each other, the input units 4 and 5 and the display unit 6 face each other, and the input units 4 and 5 and the display unit 6 are not exposed.

[0018] The housing 2 includes an upper housing 10 and a lower housing 20. The upper housing 10 is an example of a first housing. The lower housing 20 is an example of a second housing. In this embodiment, the upper housing 10 and the lower housing 20 are made of a metal material. Examples of metal materials include magnesium alloys. The upper housing 10 and the lower housing 20 may also be made of a material other than a metal, such as a resin material.

[0019] The upper housing 10 and the lower housing 20 each extend in the X direction and the Y direction. The upper housing 10 and the lower housing 20 face each other in the Z direction.

[0020] As shown in Fig. 2, the lower housing 20 has a plurality of through holes 23. The upper housing 10 has a plurality of boss portions 13 (see Fig. 4). Each of the plurality of boss portions 13 has a hole. The boss portions 13 are inserted into the through holes 23, and screws are inserted into the through holes 23 from the side opposite the boss portions 13 and screwed into the holes in the boss portions 13, thereby connecting the lower housing 20 and the upper housing 10.

[0021] The upper housing 10 faces the housing 3 when the electronic device 1 is in the closed state. The lower housing 20 is located on the opposite side of the housing 3 with respect to the upper housing 10 when the electronic device 1 is in the closed state.

[0022] The space between the upper housing 10 and the lower housing 20 is the internal space of the housing 2. A keyboard 4 and a touchpad 5 are housed in this internal space.

[0023] An outer surface 10A (see FIG. 1) of the upper housing 10 faces the liquid crystal panel 6 of the housing 3 when the electronic device 1 is in the closed state.

[0024] As shown in Fig. 1, two openings are formed on the outer surface 10A. The larger of the two openings is formed in the rear portion 11 of the upper housing 10. The smaller of the two openings is formed in the front portion 12 of the upper housing 10.

[0025] The rear portion 11 of the upper housing 10 is a portion of the upper housing 10 on one side in the Y direction. The front portion 12 of the upper housing 10 is a portion of the upper housing 10 excluding the rear portion 11, and is a portion on the other side in the Y direction. In other words, one side in the Y direction refers to the rear side, and the other side in the Y direction refers to the front side. The rear portion 11 faces a main body portion 21 of the lower housing 20, which will be described later, in the Z direction. The front portion 12 of the upper housing 10 faces two protrusions 22 of the lower housing 20, which will be described later, in the Z direction. The rear portion 11 is an example of a portion of the first housing on one side in the first direction. The front portion 12 is an example of a portion of the first housing on the other side in the first direction, and is an example of an opposing portion.

[0026] The keyboard 4 is exposed to the outside of the housing 2 through the larger of the two openings. The touchpad 5 is exposed to the outside of the housing 2 through the smaller of the two openings.

[0027] As shown in FIG. 2, the lower housing 20 includes a main body 21 and two protrusions 22.

[0028] The main body 21 is a portion of the lower housing 20 on one side in the Y direction (the rear part of the lower housing 20), and faces the rear part 11 of the upper housing 10 in the Z direction.

[0029] The two protrusions 22 are portions of the lower housing 20 on the other side in the Z direction (the front portion of the lower housing 20). The two protrusions 22 protrude forward (the other side in the Z direction) from a part of the front end of the main body 21. In this embodiment, one of the two protrusions 22 protrudes forward from the left end of the front end of the main body 21, and the other of the two protrusions 22 protrudes forward from the right end of the front end of the main body 21.

[0030] The two protrusions 22 face the front part 12 of the upper housing 10 in the Z direction. In detail, one of the two protrusions 22 faces the left end part of the front part 12 of the upper housing 10 in the Z direction, and the other of the two protrusions 22 faces the right end part of the front part 12 of the upper housing 10 in the Z direction.

[0031] A lid portion 81 is provided between the two protrusions 22. The lid portion 81 is attached to the lower housing 20 by known means such as fitting or screw fastening. The lid portion 81 is detachable from the lower housing 20.

[0032] 3 is a perspective view of the front portions of the upper and lower housings. As shown in FIG. 3, when the lid portion 81 is detached from the lower housing 20, a cavity 82 is formed between the two protrusions 22. The cavity 82 is formed by the two protrusions 22, the main body 21, and the front portion 12 of the upper housing 10. When the lid portion 81 is attached to the lower housing 20, the cavity 82 is formed by the two protrusions 22, the main body 21, the front portion 12 of the upper housing 10, and the lid portion 81. In this embodiment, a battery for supplying power to the electronic device 1 is placed in the cavity 82.

[0033] 4 is an exploded perspective view of FIG. 3. As shown in FIGS. 3 and 4, a receiving portion 24 is formed on each of the two protruding portions 22 of the lower housing 20. In this embodiment, the receiving portion 24 protrudes from the protruding portion 22 toward the cavity 82. The receiving portion 24 extends in the Y direction from the protruding base end 22A of the protruding portion 22 to the protruding tip 22B. The protruding base end 22A is a connection portion of the protruding portion 22 with the main body portion 21, and is shown imaginarily by a dashed line. The protruding tip 22B is located on the opposite side of the protruding portion 22 from the protruding base end 22A in the Y direction. The receiving portion 24 is provided on the end of the protruding portion 22 that is on the upper housing 10 side in the Z direction.

[0034] 5 is a bottom view of the front left side of the lower housing. The receiving portions 24 formed on each of the two protrusions 22 have the same configuration. Therefore, of the receiving portions 24 formed on each of the two protrusions 22, the configuration of the receiving portion 24 formed on the left protrusion 22 will be described below, and a description of the configuration of the receiving portion 24 formed on the right protrusion 22 will be omitted.

[0035] 5, each of the receiving portions 24 has three through holes 25. The through holes 25 are an example of holes. The three through holes 25 penetrate the receiving portion 24 in the Z direction.

[0036] One of the three through holes 25, through hole 25A, is formed at a tip side position 22C of protrusion 22. Tip side position 22C is a position closer to protrusion tip 22B than protrusion base end 22A of protrusion 22. In other words, tip side position 22C is a position somewhere in the front half of protrusion 22 in the Y direction. In this embodiment, through hole 25A is formed at a position within 10 mm from protrusion tip 22B.

[0037] The other through hole 25B of the three through holes 25 is formed at a base end position 22D of the protrusion 22. The base end position 22D is closer to the protrusion base end 22A than to the protrusion tip 22B of the protrusion 22. In other words, the base end position 22D is a position in the rear half of the protrusion 22 in the Y direction.

[0038] The remaining one of the three through holes 25, that is, through hole 25C, is formed between through hole 25A and through hole 25B. In this embodiment, through hole 25C is formed in the center of protrusion 22 in the Y direction.

[0039] When viewed from the Z direction, through hole 25A is circular. On the other hand, when viewed from the Z direction, through holes 25B and 25C have a shape in which the length in the X direction is longer than the length in the Y direction. In other words, through holes 25B and 25C are elongated holes.

[0040] Screws 9 (see FIG. 4) are inserted into through holes 25A and 25B. The diameter of head 91 of screw 9 is longer than the diameter of through hole 25A. The diameter of head 91 of screw 9 is also longer than the length of through hole 25B in the Y direction. Therefore, head 91 of screw 9 inserted into through holes 25A and 25B is supported by receiving portion 24 without passing through through holes 25A and 25B.

[0041] 4, boss portions 14 are formed on the front portion 12 of the upper housing 10. In this embodiment, six boss portions 14 are formed on the front portion 12 of the upper housing 10. Each of the six boss portions 14 protrudes in the Z direction from the upper housing 10 toward the protrusion 22 of the lower housing 20.

[0042] Three of the six bosses 14 face the receiving portion 24 of the right protrusion 22 of the two protrusions 22 of the lower housing 20 in the Z direction. Each of the three of the six bosses 14 can be inserted into one of three through holes 25 formed in the receiving portion 24 of the right protrusion 22.

[0043] The remaining three of the six boss portions 14 face the receiving portion 24 of the left protrusion 22 of the two protrusion portions 22 of the lower housing 20 in the Z direction. Each of the remaining three of the six boss portions 14 can be inserted into one of three through holes 25 formed in the receiving portion 24 of the left protrusion 22.

[0044] That is, when viewed from the Z direction, each of the six boss portions 14 overlaps with the through-hole 25 formed in the receiving portion 24.

[0045] 6 is a bottom view of the front left side of the upper housing. The three bosses 14 facing the receiving portion 24 of the right-side protrusion 22 in the Z direction have the same configuration as the three bosses 14 facing the receiving portion 24 of the left-side protrusion 22 in the Z direction. Therefore, the following will describe the configuration of the three bosses 14 facing the receiving portion 24 of the left-side protrusion 22 in the Z direction, i.e., the bosses 14 formed on the front left side of the upper housing 10, and will not describe the configuration of the bosses 14 formed on the front right side of the upper housing 10.

[0046] As shown in Fig. 6, one of the three boss portions 14, boss portion 14A, is formed on front portion 12 at a position facing tip end position 22C (see Fig. 5) of protruding portion 22 in the Z direction. In this embodiment, boss portion 14A is formed at a position within 10 mm from protruding tip end 22B when viewed from the Z direction. Boss portion 14A is inserted into through hole 25A. Boss portion 14A is an example of a tip end boss.

[0047] Another one of the three boss portions 14, boss portion 14B, is formed on front portion 12 at a position facing base end position 22D (see FIG. 5) of protruding portion 22 in the Z direction. Boss portion 14B is inserted into through hole 25B. Boss portion 14B is an example of a base end boss.

[0048] The remaining one of the three boss portions 14, boss portion 14C, is formed between boss portion 14A and boss portion 14B. Boss portion 14C is inserted into through hole 25C.

[0049] Holes 14Aa and 14Ba are formed in the boss portions 14A and 14B. On the other hand, no hole is formed in the boss portion 14C. Thread grooves are formed on the inner surfaces of the holes 14Aa and 14Ba. This allows screws 9 to be threaded into the holes 14Aa and 14Ba, as shown in FIG. 7. FIG. 7 is a bottom view of the front left side of the upper and lower housings. Note that a hole may be formed in the boss portion 14C into which the screw 9 is threaded, or the holes 14Aa and 14Ba may not be formed in the boss portions 14A and 14B.

[0050] Fig. 8 is a cross-sectional view of the upper and lower housings taken along line AA in Fig. 7. Fig. 9 is a cross-sectional view of Fig. 8 exploded into the upper and lower housings and screws.

[0051] The receiving portion 24 has three protrusions 26 that protrude in the Z direction toward the boss portion 14. As shown in Figures 8 and 9, a through hole 25A is formed in one of the three protrusions 26. Although not shown, the other two of the three protrusions 26 have through holes 25B and 25C formed in each.

[0052] 8 and 9, the fixing of boss portion 14A to receiving portion 24 by screw 9 will be described below. Note that the fixing of boss portion 14B to receiving portion 24 by screw 9 is similar to the fixing of boss portion 14A to receiving portion 24 by screw 9, and therefore the description thereof will be omitted.

[0053] The boss portion 14A is inserted into the through hole 25A of the receiving portion 24 from above (one side in the Z direction). At this time, the tip surface 27 of the protrusion 26 is in contact with the upper housing 10. The screw 9 is inserted into the through hole 25A of the receiving portion 24 from below (the other side in the Z direction). The screw 9 is inserted into the hole 14Aa of the boss portion 14A inserted into the through hole 25A and screwed into it. At this time, the head 91 of the screw 9 is supported by the receiving portion 24 without passing through the through holes 25A and 25B. As a result, the receiving portion 24 is sandwiched between the boss portion 14A and the screw 9. In other words, the boss portion 14A and the receiving portion 24 are fixed by the screw 9.

[0054] The boss portion 14C is inserted into the through-hole 25C of the receiving portion 24 from above (one side in the Z direction), but the boss portion 14C and the receiving portion 24 are not fixed together by the screw 9.

[0055] As shown in FIG. 9 , in this embodiment, the thickness T1 of the receiving portion 24 is 0.9 mm. Also, in this embodiment, the height H of the boss portion 14 is 2.7 mm, and the diameter R of the boss portion 14 is 3.4 mm. In this case, as shown in FIG. 8 , the total thickness T2 of the receiving portion 24 and the head 91 of the screw 9 is 3.2 mm. By setting the thickness T1 of the receiving portion 24 to 0.9 mm or more, the strength of the receiving portion 24 is increased, thereby suppressing deformation due to the elastic force of the protrusion 22 corresponding to the narrow portion described above. Furthermore, by setting the height H of the boss portion 14 to 2.7 mm or more, the engagement with the screw 9 can be strengthened. Note that the above-mentioned dimensions are those when a screw 9 with a diameter of 2 mm is used. If a screw with a diameter other than 2 mm is used, the appropriate dimensions may differ from the above-mentioned dimensions.

[0056] [effect] According to the electronic device 1 of this embodiment, the following effects can be achieved.

[0057] In this embodiment, the boss portion 14 is inserted into the through hole 25 of the receiving portion 24. Therefore, the entire periphery of the side surface of the boss portion 14 inserted into the through hole 25 faces the inner surface of the receiving portion 24 that constitutes the through hole 25, and the entire periphery of the side surface of the boss portion 14 can come into contact with the inner surface of the receiving portion 24. In other words, the receiving portion 24 can embrace the boss portion 14 over its entire periphery. This increases the strength of the connection between the boss portion 14 and the receiving portion 24. As a result, it is possible to reduce the possibility of damage to the upper housing 10 or the lower housing 20 caused by the elastic force of the protruding portion 22 of the lower housing 20 acting on the upper housing 10.

[0058] In this embodiment, the boss portion 14 is inserted along the Z direction into the through hole 25 of the receiving portion 24. Therefore, the length of the electronic device 1 in the Z direction can be made shorter than in a configuration in which the boss portion 14 is not inserted along the Z direction into the through hole 25 of the receiving portion 24 and the boss portion 14 and the receiving portion 24 are positioned adjacent to each other in the Z direction.

[0059] When the lower housing 20 is molded, a position of the protrusion 22 near the protrusion tip 22B is deformed more by thermal contraction than a position near the protrusion base end 22A of the protrusion 22. In other words, if the deformation of the protrusion 22 is corrected when the upper housing 10 and the lower housing 20 are connected, the elastic force of the protrusion 22 at the tip-side position 22C near the protrusion tip 22B is greater than the elastic force of the protrusion 22 at the base-side position 22D near the protrusion base end 22A. In this embodiment, the boss 14A is inserted into the through-hole 25A of the receiving portion 24 at the tip-side position 22C where the elastic force is greater. Therefore, the deformation of the corrected protrusion 22 due to the elastic force can be suppressed by the boss 14A and the receiving portion 24 into which the boss 14A is inserted.

[0060] According to this embodiment, through holes 25B and 25C of receiving portion 24 are elongated holes. Therefore, even if protruding portion 22 is significantly deformed and therefore misaligned with respect to upper housing 10, boss portions 14B and 14C can be easily inserted into through holes 25B and 25C of receiving portion 24.

[0061] In this embodiment, boss portions 14B and 14C, excluding boss portion 14A, are inserted into the elongated holes (through holes 25B and 25C) of receiving portion 24. This makes it possible to easily connect boss portions 14B and 14C to receiving portion 24 even if the relative positions of boss portions 14B and 14C with respect to receiving portion 24 are misaligned in the longitudinal direction of the elongated holes.

[0062] In this embodiment, the length in the X direction of the elongated hole into which the boss portion 14 is inserted is longer than the length in the Y direction of the elongated hole. Therefore, even if the deformation direction of the protrusion 22 is in the X direction, that is, even if the boss portion 14 is misaligned in the X direction with respect to the receiving portion 24, the boss portion 14 can be easily inserted into the elongated hole of the receiving portion 24.

[0063] In this embodiment, the diameter of the head 91 of the screw 9 is longer than the length of the elongated hole in the Y direction. Therefore, the screw 9 can maintain the connection between the boss portion 14 and the receiving portion 24. Therefore, the length of the elongated hole in the X direction can be increased without interfering with the ability of the screw 9 to maintain the connection between the boss portion 14 and the receiving portion 24.

[0064] Typically, when lower housing 20 is molded, the amount of deformation due to thermal contraction is smaller at a position closer to protruding base end 22A of protruding portion 22 than at a position closer to protruding tip 22B of protruding portion 22. In this embodiment, boss portion 14B is inserted into through hole 25B at base end position 22D, where the amount of deformation is smaller than at tip end position 22C, and therefore boss portion 14B and receiving portion 24 can be easily connected.

[0065] In this embodiment, the electronic device 1 is a laptop PC, but the electronic device 1 is not limited to this. The electronic device 1 may be any device in which a plurality of housings are connected together.

[0066] In this embodiment, an example has been described in which the lower housing 20 has the receiving portion 24 and the upper housing 10 has the boss portion 14, but this is not limiting. For example, the upper housing 10 may have the receiving portion 24 and the lower housing 20 may have the boss portion 14, contrary to this embodiment.

[0067] In this embodiment, an example has been described in which the electronic device 1 has six boss portions 14 and six through holes 25 into which the boss portions 14 are inserted. More specifically, an example has been described in which three through holes 25 are formed in each of the two protruding portions 22 of the lower housing 20, and a boss portion 14 is formed opposite each of the through holes 25. However, the number of boss portions 14 and through holes 25 is not limited to this. For example, two through holes 25 may be formed in each of the two protruding portions 22 of the lower housing 20, and a boss portion 14 may be formed opposite each of the through holes 25. In this case, the electronic device 1 has four boss portions 14 and four through holes 25 into which the boss portions 14 are inserted.

[0068] In this embodiment, an example has been described in which one receiving portion 24 is formed on each of the two protruding portions 22 of the lower housing 20, and three through holes 25 are formed in each of the receiving portions 24, but this is not limiting. For example, three receiving portions 24 may be formed on each of the two protruding portions 22 of the lower housing 20, and one through hole 25 may be formed in each of the receiving portions 24. In other words, one through hole 25 may be formed in one receiving portion 24.

[0069] In this embodiment, an example in which the receiving portion 24 is provided with the protrusion 26 has been described, but the receiving portion 24 does not necessarily have to be provided with the protrusion 26.

[0070] In this embodiment, an example is described in which the through hole 25A into which the boss portion 14A, which is the tip side boss, is inserted is not an elongated hole, and the through holes 25B, 25C into which the boss portions 14B, 14C, which are not tip side bosses, are inserted are elongated holes, but this is not limited to this.

[0071] For example, the through hole 25A into which the boss portion 14A, which is the boss on the tip side, is inserted may be an elongated hole. In other words, all the boss portions 14 may be elongated holes.

[0072] Also, for example, only one of the through holes 25B, 25C into which the boss portions 14B, 14C that are not tip-side bosses are inserted may be an elongated hole. In other words, at least one of the boss portions 14 may be an elongated hole, or at least one of the through holes 25B, 25C into which the boss portions 14B, 14C that are not tip-side bosses are inserted may be an elongated hole.

[0073] Furthermore, for example, neither of the through holes 25B, 25C into which the boss portions 14B, 14C that are not the tip-end bosses are inserted need be elongated holes. In other words, not all of the boss portions 14 need be elongated holes.
