[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for accommodating a battery, and more particularly to a structure for preventing rattling of the accommodated battery.

[0002]

2. Description of the Related Art Conventionally, as one of battery storage units provided in a device case of an electronic device or the like, there is one shown in FIG. In FIG. 1, a device case 1 of an electronic device is partially configured as a removable battery cover 2, and a space defined by the battery cover 2 and the device case 1 is configured as a battery storage unit 3. . The inside of the battery housing 3 is formed in a flat cylindrical shape, and the battery 4 is housed in the battery housing 3.
The battery 4 is configured as a battery in which a plurality of (here, four) batteries are bundled and connected, and the battery is packed with a shrinkable tube or the like. Then, the battery cover 2 is removed, the battery 4 is inserted into the battery storage section 3, and the battery cover 2 is attached to the device case 1.
, The battery 4 can be stored in the battery storage unit 3.

In this type of structure, since the standard value for the outer diameter of a single battery has a large tolerance, the outer diameter of the packed battery 4 varies. In addition, since the inner dimensions of the battery housing 3 are formed so as to conform to the maximum value of the outer shape of the battery 4, a gap is generated between the battery 4 and the battery housing due to variations in the battery dimensions, and the backlash is generated. Is generated, and abnormal noise is easily generated in the device case 1.

In order to prevent this, conventionally, elastic members 9 and 10 such as sponges are attached to the inner surface of the device case 1 and the inner surface of the battery cover 2 as shown in FIG.
The elastic members 9 and 10 fill the gap between the battery housing 3 and the battery 4 to prevent rattling.

[0005]

In the above-described conventional battery housing structure, the elastic members 9 and 10 are used to fill the gap between the battery housing portion 3 and the battery 4 to prevent rattling therebetween.
Is pasted, there is a problem that the pasting work becomes troublesome.

[0006] That is, in order to cope with the one elastic material, the inner surface of the battery cover 2 is placed on the inner surface of the battery in the longitudinal direction and the thickness direction.
Even when the battery is attached in an L-shape over the surface, since the area of the battery 4 that enters the battery housing portion 3 is large, the pressing in the thickness direction is not so effective and insufficient. Therefore, it is necessary to prevent the backlash by pressing the longitudinal direction with the elastic material 10 attached to the battery cover 2 and the thickness direction with the elastic material 9 attached to the device case 1. Since the elastic material 9 to be attached to the inside is attached to the inner surface of the cylindrical space, the assembling workability is extremely deteriorated.

Further, since two elastic members 9 and 10 are used, there is a problem that the number of parts and the cost of parts increase.

An object of the present invention is to provide a battery housing structure in which the number of parts is reduced and the workability of assembly is improved.

[0009]

The battery housing structure of the present invention includes a part of the equipment case on the bottom surface and the inner back side of the equipment case facing the battery housing defined by the equipment case and the battery cover. A pressing portion formed in a tongue shape and provided with an elastic force is provided. One pressing portion is pressed against the device case, and the other pressing portion is pressed against the battery cover.

In this configuration, the battery accommodated in the battery accommodating portion comes into contact with the protruding portion and is pressed by the elastic force of the pressing portion against the inner surface of the device case or the inner surface of the battery cover. Prevent rattling.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view of an embodiment of the battery housing structure of the present invention, and FIG. 2 is a partially cutaway side view thereof. In these figures, reference numeral 1 denotes an electronic device case formed of resin or the like, and an opening is provided in a part thereof. A battery cover 2 is detachably provided in this opening, and a flat cylindrical space is defined by the battery cover 2 and the device case 1, and this space is configured as a battery storage unit 3. Further, reference numeral 4 denotes a battery, which is configured as a plurality of (here, four) batteries which are bundled and connected and covered with a shrink tube or the like as in the past.

Here, the internal dimensions of the battery housing 3 are as follows:
Pressing pieces 5, 6 formed by cutting a part of the device case 1 in a tongue shape on the inner bottom surface and the inner rear side surface of the device case 1 while being set to be larger than the maximum value of the outer dimensions of the battery 4. Is provided. The pressing pieces 5 and 6 have some elasticity depending on the material of the device case 1, and each tip has a position smaller than this size, assuming the minimum value of the external dimensions of the battery 4. The projections 7, 8 with the leading edge positioned at the top are integrally formed. Needless to say, the pressing pieces 5, 6 and the projections 7, 8 can be formed simultaneously with the resin molding of the device case 1.

Therefore, according to this configuration, after the battery cover 2 is removed, the battery 4 is inserted into the battery storage section 3, and the battery cover 2 is mounted on the equipment case 1, whereby the storage of the battery is realized. . And the battery 4 stored at this time is
The inner and bottom surfaces of the pressing pieces 5 and 6 abut against the projections 7 and 8 of the pressing pieces 5 and 6, respectively, and are pressed against the inner surface of the device case 1 and the inner surface of the battery cover 2 by the elastic force of the pressing pieces 5 and 6, respectively. You. Thereby, the gap between the inner shape of the battery housing 3 and the outer shape of the battery 4 is absorbed, and it is possible to prevent rattling between the two.

This eliminates the need for an operation of bonding a plurality of elastic members as in the related art, thereby reducing the number of parts and improving the assembling workability.

[0016]

As described above, according to the present invention, a pressing portion provided with an elastic force is provided on a part of a device case facing a battery housing portion, and a protrusion contacting the outer surface of the battery is provided by the pressing portion. The battery housed in the battery housing is pressed against the inner surface of the device case or the inner surface of the battery cover by the protrusion and the pressing portion, and the backlash between the battery housing and the battery is reduced. Can be prevented. This eliminates the need for a plurality of elastic members to prevent rattling, thereby reducing the number of parts and improving the assembly workability.
