In the configuration example shown in FIG. 2, eight fastening portions 37 are provided. The battery frame 34 is screwed and fixed to the inner surface 23 a of the second housing member 23 using the fastening portion 37 , thereby fixing the battery device 32 to the second housing member 23 .

Next, the connection structure of the housing members 22 and 23 will be described.

FIG. 3 is an enlarged schematic perspective view of the second hook 44 provided on the battery frame 34 and its peripheral portion. FIG. 4 is a schematic side cross-sectional view of the housing 12 enlarging the first hook 42, the second hook 44, and their surroundings.

As shown in FIGS. 1 and 3, the first housing member 22 is a plate-like member that forms the lower surface 12b of the housing 12. As shown in FIG. As shown in FIGS. 1 and 2, the second housing member 23 is a plate-like member that forms the upper surface 12a of the housing 12, and vertical walls that form the side surfaces of the housing 12 are formed on the four peripheral edges. It has a bathtub shape. The housing members 22 and 23 are mostly made of metal, for example, a magnesium alloy, except that the antenna 30 is surrounded by resin. The shape and material of the housing members 22 and 23 can be changed as appropriate.

As shown in FIG. 2, the housing members 22 and 23 are detachably connected to each other using a plurality of connecting portions 38 arranged along their outer peripheral edges. The connecting portion 38 is a screw that is screwed into a female thread formed on the inner surface 23 a of the second housing member 23 through a through hole formed in the first housing member 22 , for example. A part or all of the connecting part 38 arranged on the front edge part is constituted by an engaging part for engaging a hook provided on one of the housing members 22 and 23 with an engaging hole provided on the other. .

By the way, as described above, the central portion of the first housing member 22 on the side of the lower surface 12b that does not have an upright wall swells downward only with the connecting portions 38 provided at the outer peripheral portions of the housing members 22 and 23. There is a concern that scratches may occur due to friction with a desk or the like. Therefore, the housing 12 of the present embodiment further includes a pair of left and right connecting portions 40 , 40 substantially centrally of the housing members 22 , 23 .

As shown in FIGS. 2 to 4, the left and right connecting portions 40 have the same or similar structures, and therefore will be described without particular distinction. The connecting portion 40 has a first hook 42 and a second hook 44 .

As shown in FIGS. 3 and 4 , the first hook 42 is provided so as to protrude from the inner surface 22 a of the first housing member 22 . The first hook 42 is formed integrally with the first housing member 22 . That is, the first hook 42 is made of the same metal as the first housing member 22, and is made of magnesium alloy in this embodiment. Therefore, the first hook 42 has high strength and rigidity. The first hook 42 is formed at the same time as the first housing member 22 is formed, or formed by cutting or the like after the first housing member 22 is formed. The first hook 42 may be configured as a separate part from the first housing member 22 and fixed to the inner surface 22a by welding, adhesion, or the like. When the first hook 42 is formed as a separate part from the first housing member 22, it is preferable that the first hook 42 is made of, for example, a PC-ABS alloy resin.

The first hook 42 has a base portion 42a, a projecting portion 42b, a first claw portion 42c, and an inclined surface 42d.

The base portion 42a is a plate provided along the inner surface 22a. The projecting portion 42b is a plate projecting upward from the base portion 42a. The base portion 42a may be omitted, and in this case, the projection portion 42b of the first hook 42 may directly project from the inner surface 22a.

The first claw portion 42 c is a claw-shaped portion provided at the tip of the first hook 42 . The first claw portion 42c protrudes rearward from the tip of the projecting portion 42b. 42 d of inclined surfaces are provided in the upper surface of the 1st nail|claw part 42c. The inclined surface 42d is a surface that is gradually inclined downward toward the front.

As shown in FIGS. 3 and 4, the second hook 44 can be engaged with and disengaged from the first hook 42 . The second hook 44 protrudes from the outer peripheral end surface 34a of the battery frame 34 and is bent to have a substantially L shape in a side view. The second hook 44 is provided on the rearward surface of the outer peripheral end surface 34a of the battery frame 34 (see also FIG. 2). Since the second hook 44 is molded integrally with the battery frame 34 , it is made of resin like the battery frame 34 . The second hook 44 may be molded at the same time as the battery frame 34 is molded. The second hook 44 may be configured as a separate component from the battery frame 34 and fixed to the battery frame 34 by screwing, bonding, or the like.

The second hook 44 has a lateral protruding portion 44a, a longitudinal protruding portion 44b, a second claw portion 44c, and an inclined surface 44d.

The lateral protrusion 44a is a plate that protrudes rearward from the outer peripheral end surface 34a. The vertical protruding portion 44b is a plate that continues from the distal end of the lateral protruding portion 44a via a bent portion 44e and protrudes downward. The bent portion 44e is bent at 90 degrees between the projecting portions 44a and 44b. The vertical projection 44b is arranged in parallel just before the projection 42b of the first hook 42. As shown in FIG. Between the projecting portion 42b and the vertical projecting portion 44b, a gap slightly larger than the projecting length of the claw portions 42c and 44c is formed.

The second claw portion 44 c is a claw-shaped portion provided at the tip of the second hook 44 . Specifically, the second claw portion 44c protrudes rearward from the tip of the vertical protruding portion 44b that stands up toward the inner surface 22a of the first housing member 22 . 44 d of inclined surfaces are provided in the lower surface of the 2nd nail|claw part 44c. The inclined surface 44d is a surface that is gradually inclined upward toward the rear. The inclined surface 44 d is substantially parallel to the inclined surface 44 d of the first hook 42 .

Thus, the second hook 44 protrudes from the outer peripheral end surface 34a of the battery frame 34 in a substantially L shape when viewed from the side. Also, the second hook 44 is made of resin, like the battery frame 34 . Therefore, the second hook 44 can swing back and forth about the bent portion 44e. As a result, the second claw portion 44c can be elastically displaced substantially in the front-rear direction (see FIGS. 4 and 5). Here, the protrusion length of the lateral protrusion 44a, that is, the gap between the vertical protrusion 44b and the outer peripheral end surface 34a is slightly larger than the protrusion length of the second claw portion 44c from the vertical protrusion 44b. This gap is for allowing elastic displacement of the projecting portion 44b and the second claw portion 44c.

As shown in FIGS. 2-4, the second hook 44 is positioned adjacent to the fastening portion 37 . Specifically, the pair of second hooks 44 are arranged side by side with the fastening portion 37 projecting rearward from the outer peripheral end surface 34a (see FIG. 2). In the case of the present embodiment, the second hooks 44 are positioned laterally off the lateral center of the housing 12 . The number of installed second hooks 44 may be one or three or more.

The second hook 44 is arranged in a gap C formed between the front end surface 26 a of the board 26 and the rear outer peripheral end surface 34 a of the battery frame 34 . In the configuration example shown in FIG. 2, a notch-shaped recess 26b recessed rearward is formed in the front end face 26a of the substrate 26, and the second hook 44 is arranged in this recess 26b.

FIG. 5 is a side sectional view schematically showing the operation of connecting the housing members 22 and 23 shown in FIG.

When attaching the first housing member 22 to the second housing member 23, first, the housing 12 is turned upside down, and the upper surface 12a of the second housing member 23 is placed on a desk or the like. Next, the first housing member 22 is tilted forward downward, and, for example, the connecting portions 38 at the front edge portions of the housing members 22 and 23 are temporarily fixed.

Subsequently, the first hook 42 is engaged with the second hook 44 while the rear end of the first housing member 22 is lowered onto the first housing member 22 . The engagement of the hooks 42 and 44 is, as shown in FIG. Then, the inclined surface 42 d of the first hook 42 slides on the inclined surface 44 d of the second hook 44 . Then, due to the pressing force between the inclined surfaces 42d and 44d, the vertical protrusion 44b elastically deforms forward and swings. As a result, the second claw portion 44c is elastically displaced forward away from the first claw portion 42c, so that the first claw portion 42c smoothly climbs over the second claw portion 44c and engages with each other (see FIG. 4).

Finally, by fixing all the remaining connecting portions 38, the connecting work of the housing members 22 and 23 is completed.

As described above, the electronic device 10 of the present embodiment includes the first hook 42 provided so as to protrude from the inner surface 22a of the first housing member 22 and having the first claw portion 42c at the tip, and the battery frame 34. A second claw portion 44c that can be elastically displaced by protruding from the outer peripheral end face 34a and being bent, and that is capable of engaging with the first claw portion 42c is provided at the tip that stands up toward the inner surface 22a of the first housing member 22. and a second hook 44 attached.

Therefore, the electronic device 10 can suppress the bending and deformation of the central portion of the first housing member 22 due to the engagement between the hooks 42 and 44, and the connection strength between the housing members 22 and 23 can be increased. Secured. Further, the electronic device 10 is provided so that the second hook 44 on the second housing member 23 side protrudes from the outer peripheral end face 34 a of the battery frame 34 of the battery device 32 . Therefore, an installation space for the second hook 44 and an engagement space for the hooks 42 and 44 are formed outside the battery device 32 . As a result, the hooks 42 and 44 do not erode the volume of the battery device 32, and reduction in battery capacity can be suppressed.

At this time, the second hook 44 protrudes from the outer peripheral end surface 34a of the battery frame 34 and is bent, and is formed in a substantially L shape when viewed from the side, so that the second hook 44 is smoothly elastically displaced. Therefore, when the hooks 42 and 44 are engaged or disengaged, the second claw portion 44c of the second hook 44 is smoothly elastically displaced and escapes from the first claw portion 42c of the first hook 42. FIG. As a result, the attachment and detachment operations of the housing members 22 and 23 can be performed more smoothly, and the hooks 42 and 44 can be prevented from being damaged during the engagement and disengagement operations. Moreover, the second hook 44 is substantially L-shaped when viewed from the side, and can be configured to have a simple shape and a minimum size. Therefore, it is possible to further suppress the second hook 44 from eroding the battery capacity, and the arrangement in the narrow gap C is easy.

Also, the second hook 44 may be formed integrally with the battery frame 34 made of resin. Thereby, the second hook 44 can easily obtain a structure having moderate elasticity. At this time, since the second hook 44 is integral with the battery frame 34 at the base lateral protrusion 44a, high strength can be obtained even though it is made of resin. As a result, the electronic device 10 can prevent the second hook 44 from being damaged even when the housing members 22 and 23 are repeatedly attached and detached.

The first hook 42 may be formed integrally with the metal first housing member 22 . This eliminates the need for an additional part for the first hook 42 , reducing the number of parts and cost, and increasing the strength of the first hook 42 . In addition, since the second hook 44 of the electronic device 10 can be elastically displaced, the first hook 42 need not be elastically displaced.

The second hook 44 may be positioned adjacent to the fastening portion 37 for fixing the battery frame 34 to the second housing member 23 . If the second hook 44 is located far from the fastening portion 37, when the second hook 44 receives a pulling force from the first hook 42, the resin battery frame 34 is bent, and as a result, the first housing There is concern that the member 22 may bend. In this regard, in the electronic device 10 , the second hook 44 is arranged close to the fastening portion 37 . Therefore, the second hooks 44 can hold the first hooks 42 with high rigidity even when subjected to a tensile force from the first hooks 42, and the bending deformation of the first housing member 22 is further ensured. can be suppressed.

The second hook 44 may be arranged in a gap C formed between the board 26 and the outer peripheral end surface 34 a of the battery frame 34 . In this way, the electronic device 10 can secure installation space for the hooks 42 and 44 while maximizing the battery capacity by bringing the rear end surface of the battery device 32 as close to the front end surface 26a of the substrate 26 as possible.

At this time, the second hook 44 may overlap the substrate 26 in the thickness direction of the housing 12 (see FIG. 4). As a result, the second hook 44 can ensure the maximum standing length of the vertical protruding portion 44b, the elastic displacement of the second claw portion 44c becomes smoother, and the amount of displacement becomes more sufficient. On the other hand, the first hook 42 may be located below the bottom surface of the substrate 26 and may not overlap the substrate 26 in the thickness direction of the housing 12 (see FIG. 4). 4, the gap C between the front end surface 26a of the substrate 26 and the outer peripheral end surface 34a can be made narrower, and the battery capacity can be further increased.

It goes without saying that the present invention is not limited to the above-described embodiments, and can be freely modified without departing from the gist of the present invention.
