The frame palm rest 44 is formed with engagement holes 64 at predetermined intervals in the Y direction on one (left side) side end 44A thereof. The engagement hole 64 engages with the engagement portion 25 shown in FIG. 4 of the palm rest unit 10 when the palm rest unit 10 and the main body unit 11 are combined. The shape of the engagement hole 64 is, for example, a substantially concave shape.

FIG. 12 is a partially enlarged perspective view of the vicinity of the right side end of the main unit 11 shown in FIG.
The frame palm rest 44 includes a side end portion 44B at a side end opposite to the side end portion 44A. Engagement holes 65 are formed at predetermined intervals in the Y direction at the other side end 44 </ b> B of the frame palm rest 44. The engaging hole 65 engages with the engaging portion 28 shown in FIG. 4 of the palm rest unit 10 when the palm rest unit 10 and the main unit 11 are combined. The shape of the engagement hole 65 is, for example, a substantially concave shape. That is, the engagement hole 65 has a shape that is symmetrical to the engagement hole 64.

13 is a cross-sectional view of the frame palm rest 44 shown in FIG.
The frame palm rest 44 includes an engaging claw 66 that engages with the engaging portion 30 of the palm rest 12. The engaging claw 66 has a substantially rectangular cross section that fits into the concave portion 31 of the engaging portion 30 of the palm rest 12.

FIG. 14 is a cross-sectional view of the main body 3 shown in FIG.
On the side wall 12D of the palm rest 12, an engagement protrusion 70 that protrudes from the side wall 12D toward the outside of the palm rest 12 is formed. The direction in which the engagement protrusion 70 protrudes is, for example, the Y direction orthogonal to the longitudinal direction of the frame palm rest 44 (X direction in FIG. 14).

  An engagement claw 71 that engages with the engagement protrusion 70 is formed on the frame palm rest 44. The direction in which the engaging claws 71 protrude is a direction (Y direction shown in FIG. 14) orthogonal to the longitudinal direction of the frame palm rest 44.

  Next, as shown in FIG. 3, a welding pin (not shown) of the palm rest 12 is inserted into the hole 17 of the keyboard 13 and welded (ST1504). Thereby, the palm rest 12 and the keyboard 13 are welded at a plurality of locations, and the palm rest unit 10 shown in FIG. 2 is manufactured.

  Next, the process of combining the palm rest unit 10 with the main unit 11 will be described.

  20 is a plan view showing a state in which the palm rest unit 10 is overlapped with the main body unit 11 while being displaced, and FIG. 21 is a cross-sectional view of the palm rest unit 10 and the main body unit 11 shown in FIG. In FIG. 20 and subsequent figures, the illustration of the hinge 4 is omitted.

  First, as shown in FIG. 20, the palm rest unit 10 is overlapped with the main unit 11 in a slightly displaced state (ST1505). That is, the main body unit 11 and the palm rest unit 10 are shifted and overlapped in a direction orthogonal to the longitudinal direction of the palm rest unit 10 (Y direction in FIG. 20).

  At this time, as shown in FIG. 21, the engaging portion 30 of the palm rest 12 is not engaged with the engaging claws 66 of the frame palm rest 44. That is, the engaging portion 30 is aligned with the stepped portion 76 of the frame palm rest 44. Further, the engaging portion 25 of the palm rest 12 is in a state of entering the engaging hole 64 of the frame palm rest 44, but the engaging portion 25 and the engaging hole 64 are not fitted. Further, the engagement protrusion 70 of the frame palm rest 44 is not fitted to the engagement claw 71 of the palm rest 12. Further, the engagement protrusion 18 of the receiving plate 15 is in a state where it enters the engagement hole 61 of the frame palm rest 44, but the engagement protrusion 18 and the engagement hole 61 are not fitted. .

  22 is a plan view showing a state in which the palm rest unit 10 is slid and combined with the main body unit 11, and FIG. 23 is a DD cross-sectional view of the palm rest unit 10 and the main body unit 11 shown in FIG.

  Next, as shown in FIG. 20, the main body unit 11 and the palm rest unit 10 are combined by sliding the palm rest unit 10 in the Y direction with respect to the main body unit 11 (ST1506).

  As a result, as shown in FIG. 23, the engaging portion 30 of the palm rest 12 engages with the engaging claw 66 of the frame palm rest 44. Further, the engaging portion 25 of the palm rest 12 is fitted into the engaging hole 64 of the frame palm rest. Specifically, the first wall portion 26 overlaps the frame palm rest 44 and abuts on the protrusion 80. The second wall portion 27 abuts against an end portion that forms the engagement hole 64 of the frame palm rest 44. The protruding portion 80 is a protruding portion formed so as to protrude from the surface 81 on the side facing the bottom 41 of the frame palm rest 44. Further, the claw 62 is fitted in the engagement hole 19 of the engagement protrusion 18. When the palm rest unit 10 is slid with respect to the main body unit 11, the hook portion 18 </ b> B reliably guides the claw portion 62 into the engagement hole 19.

<Action etc.>
As described above, according to the present embodiment, the main body 3 of the electronic device 1 includes the frame palm rest 44 on which the printed circuit board 42 and the heat dissipation unit 43 can be mounted. By screwing a screw into the boss 60 of the frame palm rest 44 from the frame palm rest 44 side, the frame palm rest 44 and the bottom 41 are integrated by this screw.

  For this reason, since it is not necessary to fix the printed circuit board 42 and the heat radiating unit 43 to the bottom 41, it is not necessary to form a boss | hub, a rib, etc. in the bottom 41. FIG. Accordingly, the boss 47, screw holes, ribs and the like are not formed on the inner surface 46 of the bottom 41 except for the peripheral edge of the bottom 41. As a result, the exterior surface 45 of the bottom 41 is superior in design because no sink marks or the like are formed at the time of molding, compared to a bottom having a boss or rib.

  The frame palm rest 44 is substantially the same size as the bottom 41 and, for example, magnesium is used as the constituent material thereof, so that the strength of the main body 3 can be reliably ensured. In particular, the strength against twisting or bending of the main body 3 can be improved.

  As shown in FIG. 4, a plurality of engaging protrusions 16 and 18 are formed on the bottom surface of the receiving plate 15 of the palm rest unit 10 in a dispersed manner. Further, as shown in FIG. 4, a plurality of engaging portions 25 are formed on the inner surface of the side wall 12 </ b> A of the palm rest 12, and a plurality of engaging portions 28 are formed on the inner surface of the side wall 12 </ b> B of the palm rest 12. ing. A plurality of engaging portions 30 are formed on the side wall 12 </ b> C of the palm rest 12. An engagement protrusion 70 is formed on the side wall 12D of the frame palm rest 12 (see FIG. 14).

  On the other hand, an engagement hole 61 is formed on the surface of the frame palm rest 44 as shown in FIG. As shown in FIG. 11, a plurality of engagement holes 64 are formed in one side end 44 </ b> A of the frame palm rest 44. A plurality of engagement holes 65 are formed in the other side end 44B of the frame palm rest 44 as shown in FIG. As shown in FIG. 13, an engaging claw 66 is formed on the frame palm rest 44. Then, an engaging claw 71 is formed at the end of the frame palm rest 44 opposite to the side where the engaging claw 66 is formed, as shown in FIG.

  As a result, as shown in FIG. 23, by engaging the palm rest unit 10 in the Y direction with respect to the main unit 11, the engaging protrusions 16 and 18 are fitted in the engaging holes 61, and a plurality of engaging portions 25 and the engaging portion 28 are fitted in the engaging holes 64 and the like, respectively. Then, the engaging claws 66 fit into the plurality of engaging portions 30, and the engaging projections 70 fit into the engaging claws 71. As a result, the palm rest unit 10 and the main unit 11 can be combined and integrated without using screws or the like. As a result, a screw or the like is not exposed from the front surface side and the back surface side of the main body portion 3, and the main body portion 3 excellent in design can be realized.

  Further, the number of screws conventionally used for combining the main unit and the palm rest unit can be reduced. Specifically, in the past, 74 screws were used, but in this embodiment, the number can be reduced to 52.

  Further, the plurality of engaging protrusions 16 and 18 on the bottom surface of the receiving plate 15 of the palm rest unit 10 are fitted into the plurality of engaging holes 61 of the frame palm rest 44 and are hooked and connected at a plurality of dispersed positions. As a result, the keyboard 13 can be prevented from floating, and the keyboard feeling felt by the user can be improved.

  The heat dissipation unit 43 includes, for example, a heat pipe but does not include a heat dissipation fan. As a result, the size and thickness of the heat dissipation unit 43 can be reduced, and as a result, the main body 3 can be reduced in size and thickness.

  As shown in FIG. 14, the heat dissipation unit 43 is provided in contact with the electronic component 73 and the frame palm rest 44. Therefore, the heat generated by the electronic component 73 and the like can be dispersed by the heat radiating unit 43 and can be dispersed in a wider range by the frame palm rest 44. As a result, the heat generated in the electronic component 73 and the like can be efficiently dispersed and the inside of the main body 3 can be cooled.

  The engaging protrusion 18 of the receiving plate 15 of the palm rest unit 10 includes a flange 18B. For this reason, as shown in FIGS. 20 and 21, when the palm rest unit 10 is slightly shifted with respect to the main body unit 11, the engagement protrusion 18 may not enter the engagement hole 61 of the frame palm rest 44. Conceivable. However, in this case, the flange portion 18 </ b> B is placed on the surface of the frame palm rest 44. As a result, the operator can easily know that the palm rest unit 10 is not aligned with a predetermined position with respect to the main unit 11. Therefore, the palm rest unit 10 and the main unit 11 can be combined with each other more reliably, and productivity can be improved.

  In the said embodiment, the example which combined the main body unit 11 and the palm rest unit 10 by sliding the palm rest unit 10 with respect to the main body unit 11 was shown. However, the method of combining the main unit 11 and the palm rest unit 10 is not limited to this.

<Modification>
FIG. 24 is a cross-sectional view of the vicinity of a screwing portion of a main body portion of an electronic device according to a modification. In the present modification, the same components as those in the above embodiment are denoted by the same reference numerals, description thereof will be omitted, and different points will be mainly described.

  The electronic device according to the present modification does not include the engagement protrusion 16 and the engagement hole 61 necessary for combining the main unit and the palm rest unit by sliding compared to the above embodiment, and the palm rest 12 ′ and the frame palm rest 44 ′. And are screwed at the four corners.

  That is, screw holes 90 are formed at the four corners of the palm rest 12 ′, and screw holes 92 are formed at the positions of the frame palm rest 44 ′ corresponding to the screw holes 90. The palm rest unit and the main unit are overlapped, and screws 93 are screwed into these screw holes 90 and 92 from the screw hole 90 side. The upper end of the screw 93 is located behind the screw hole 90 from the surface of the palm rest 12 ′. A cushion member 94 is embedded in the screw hole 90. The cushion member 94 is a blindfold member that blinds the screw hole 90 and is a cushioning member for buffering an impact that occurs when the display portion is closed with respect to the main body portion.

  According to such a configuration, the palm rest 12 ′ and the frame palm rest 44 ′ can be connected by the screw 93, and the shock generated when the screw hole 90 is blinded and the display unit is closed by the cushion member 94 is buffered. can do. Therefore, as in the above-described embodiment, the screw holes and the like can be made invisible from the surface, so that it is possible to realize the electronic device 3 ′ having excellent design.

  The present invention is not limited to the above embodiment. The present invention can be implemented with various modifications within the scope of its technical idea. The scope of implementation belongs to the technical scope of the present invention.

  In the above embodiment, the heat radiation unit 43 and the printed board 42 are mounted on the frame palm rest 44 and screwed to the bottom 41 (ST1501-ST1503), and then the keyboard 13 and the palm rest 12 are welded (ST1504). However, even if ST1504 is performed before ST1501-ST1503, electronic device 1 can be similarly manufactured.

  As long as the engagement protrusions 16 and 18 of the palm rest unit 10 and the engagement hole 61 of the frame palm rest 44 can be engaged with each other by sliding, the shape of each other is not particularly limited.

  The shape of the engagement hole 64 is not particularly limited as long as it is a shape that can be engaged with the engagement portion 25, and can be changed as appropriate. Further, the number of the engagement holes 64 can be appropriately changed according to the size of the frame palm rest 44. The shape of the engagement hole 65 is not particularly limited as long as it is a shape that can be engaged with the engagement portion 28, and can be changed as appropriate. For example, the shape of each engagement hole 65 may be different. Even with such a configuration, the palm rest unit 10 and the main unit 11 can be combined in the same manner as in the above embodiment.
