It had a battery storage structure for storage by sliding fitting. In particular, for example, a portable telephone is intended to be carried, so that it is required to be reduced in size and thickness, and a battery is arranged together with electronic components in an installation space in this narrow case, and a cover is slide-fitted. It is important to efficiently provide a space for this. FIG. 4 is a perspective view showing a conventional battery housing structure employed in such a mobile phone. FIG. 5 is an operation explanatory view showing the fitting operation of the cover 40 shown in FIG.

As shown in FIG. 4, a conventional battery housing structure adopted for a mobile phone includes a case 30 for a mobile phone provided with a housing capable of housing internal components such as an antenna member 39 and a battery, and a case 30 for this case. And a cover 40 that slides and fits. Here, case 30
Is integrally formed with a storage section 31 formed in a concave shape for storing a battery (not shown). This storage part 3
1, a plurality of fitting recesses 32a, 32b, 32c, 32d projecting symmetrically and a rail 38 having concave grooves extending symmetrically in parallel are integrally formed on both side walls in the left-right direction shown in FIG. It is forming. In the peripheral wall of the storage section 31, a rear end fitting concave portion 35 is formed at the rear of the left and right center shown in FIG. 4, and a rectangular engaging hole 36 is formed at the front end.

On the other hand, the cover 40 has side walls at the left and right ends and a rear end of the outer periphery formed in a rectangular thin plate shape, and a plurality of convex portions protruding and extending inward from both ends of the side walls symmetrically from the ends. 42a, 42b, 42c, 42d and a rear end protruding portion 45 protruding inward from the center of the rear portion are integrally formed. The cover 40 is provided on the rail 3 provided on the case 30.
8 and slide projections 48 for guiding the slide operation
Are integrally formed. Further, the cover 40 is formed with a locking claw 46 having a claw shape at the front end of the rear end projection 45 so as to engage with the engagement hole 36 and lock when slidingly fitting the case 30. Is formed.

[0005] In the conventional battery housing structure employed in the mobile phone formed as described above, when the cover 40 is slid and fitted into the housing 31 of the case 30, first, as shown in FIG. The slide projection 48 is aligned with the rear of the slide 38 and inserted. At this time, the protrusions 42a, 42
c is the fitting recesses 32a, 32c and the fitting recesses 32b, 32
d. The case 30 and the cover 40 are fitted by setting the slide protrusion 48 and the protrusion 42 at predetermined positions in this manner. Then, when the case 30 and the cover 40 are fitted, the cover 40 is slid in the forward direction shown in FIG. As a result, the convex portion 42 and the rear end convex portion 45 can be fitted into the fitting concave portion 32 and the rear end fitting concave portion 35 to fix the cover 40 to the case 30. At this time, the cover 40 is attached to the case 30
Is locked by being inserted into the engaging hole 36 and engaging the claw portion.

As described above, the conventional battery housing structure has a plurality of protrusions 42 projecting symmetrically on both sides of the cover 40.
a, 42b, 42c, and 42d are provided, and the cover 40 and the case 3 are slid and fitted into the plurality of fitting recesses 32a, 32b, 32c, and 32d provided in the case 30.
0 was fixed.

[0007]

However, in the conventional battery housing structure, as shown in FIG. 4, for example, when the antenna member 39 is moved into the housing 31 to reduce the total length D of the case 30, the size is reduced. Since the fitting concave portion 32c is located between the antenna member 39 and the storage portion 31 and cannot move the antenna member 39, it is difficult to reduce the size of the case 30. In addition, since the space of the fitting recess 32 is secured on the side surface of the case 30 as described above, there is a problem that the space efficiency in the case 30 is deteriorated. Also,
In the conventional battery housing structure, as shown in FIG.
When the protrusion 42 is slid into the fitting recess 32 a plurality of times and fitted, there is a problem that rattling in the left-right direction occurs and it becomes difficult to effectively fix the fitting. The present invention solves such a conventional problem and provides a battery housing structure that prevents rattling of a cover that occurs in a battery housing of an electronic device case and improves the efficiency of an internal arrangement space. With the goal.

[0008]

and an engaging portion 13b protruding in the vicinity of a.
Therefore, when the engaging protrusion 23 of the cover 20 is engaged with the engaging recess 13, the engaging protrusion 23 is housed inside the engaging recess 13 and does not protrude from the side surface. Can be widely provided.

The storage section 11 of the case 10 has
As shown in the figure, a rib 14 and an opening hole 14a are formed at the front end to form a structure in which the projection 24 of the cover 20 is fitted to eliminate the fitting portion such as the fitting recess 12a. Therefore, an arrangement space can be secured at this position, and components such as the antenna member 19 can be arranged. Accordingly, the case 10 can be made smaller in overall length C shown in FIG. 1 than in the conventional case shown in FIG.

An embodiment in which the battery housing structure according to the present invention thus formed is employed in a mobile phone,
When the cover 20 is slid and fitted into the storage section 11 of the case 10, first, as shown in FIG.
The slide projection 28 is aligned with the rear part, and the projection 24 is brought into contact with the rib 14 as shown in FIG. At the same time, the engaging projection 23 of the cover 20 is inserted into the notch 13a of the engaging recess 13 as shown in FIG.

When the case 10 and the cover 20 are fitted as described above, the cover 20 is slid in the forward direction shown in FIG. At this time, the cover 20 slides with the slide projection 28 and the projection 24 being guided by the rail 18 and the rib 14. Then, the cover 20 is fixed to the case 10 by the protrusion 22 and the rear end protrusion 25 being fitted into the fitting recess 12 and the rear fitting recess 15, respectively. In addition, the locking claw 26 of the cover 20 includes the convex portion 22 and the rear end convex portion 25.
Are respectively fitted into the fitting concave portion 12 and the rear end fitting concave portion 15, and at the same time, they are inserted into the engaging holes 16 of the case 10 and locked by engaging the claws. Thus, the cover 20
Is fixed by sliding into the storage section 11 of the case 10.

Although the embodiment of the battery housing structure according to the present invention has been described in detail, the present invention is not limited to the above-described embodiment, and can be changed without departing from the gist thereof. . For example, although the embodiment in which the battery housing structure according to the present invention is applied to a mobile phone has been described, the present invention is not particularly limited to a mobile communication terminal such as a mobile phone, and may be applied to an electronic device such as a remote controller. Applicable.

[0021]

As described above, according to the battery housing structure of the present invention, the structure of the fitting recess formed on the side surface of the case is made up of protrusions and ribs, so that the internal space can be used and installed. The space can be efficiently improved, and the entire case of the electronic device can be reduced in size. In addition, according to the battery housing structure of the present invention, since the protrusion of the cover is provided so as to be guided along the rib and slidably fit in the case, the protrusion has a play in the lateral direction of the cover. It can be effectively prevented.
