DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a battery pack used in a portable electronic device such as a portable telephone inside the device.

[0002]

2. Description of the Related Art With the rapid spread of mobile communication networks, portable electronic devices such as mobile phones have been reduced in size.
Many of such portable electronic devices adopt a structure in which a separate rechargeable battery pack is incorporated.

[0005] For example, as shown in FIG. 5, a conventional battery pack 1 includes a storage portion 2 a provided on the back of a mobile phone main body 2.
Cushioning material 3a such as a sponge attached to the back surface of a battery cover 3 which is detachably fixed to the battery cover 3 and forms a casing of the electronic device.
Is pressed toward the mobile phone main body 2 to be fixed.

The battery cover fixing means engages a locking claw 3b provided at one end of the battery cover 3 with a recess provided in the portable telephone body 2 and a stopper receiving member provided at the other end. The hole 3c is fixed by fitting a stopper 4 slidably provided in the mobile phone main body 2.

[0005]

As described above, resin components including the battery cover 3 are used for the components such as the casing of the mobile phone, as described above. The thickness is also thinner. Therefore, when a shock is applied to the mobile phone main body 2 such as when the mobile phone is dropped or the like, the built-in battery pack 1 pushes the battery cover 3 back through the cushioning material 3a or directly hits the battery cover 3 or the like. As a result, the battery cover 3 was elastically deformed, the engagement portions were disengaged, and the battery cover 3 was detached from the mobile phone main body 2 in some cases.

To prevent the battery cover 3 from coming off,
It is conceivable to increase the fitting amount (shown by A in the figure) of the stopper 4 to the stopper receiving hole 3c, that is, to lengthen the fitting portion of the stopper 4, but if this is adopted, the sliding amount of the stopper 4 ( (Indicated by B in the figure). However, increasing the slide amount of the stopper 4 leads to an increase in the slide structure itself, and it is impossible to reduce the size of the mobile phone.

In addition to the battery pack fixing structure shown in FIG. 5, a cover-integrated battery in which a rechargeable battery is incorporated in a battery cover as in a battery pack storage structure disclosed in Japanese Utility Model Application No. 6-60052, for example. Some use a structure that uses a pack. However, even in such a structure, since the impact due to the self-weight or drop of the rechargeable battery is directly applied to the battery cover, similarly, there is a problem that the battery cover is easily detached.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a battery pack fixing structure for a mobile phone, which does not cause a battery cover or a battery pack to come off even when subjected to an impact due to a fall or the like. I have.

[0009]

As means for solving the above-mentioned problems, a pair of gripping portions which are supported in a housing of an electronic device so as to be able to approach and separate from each other, and the pair of gripping portions are directed in the approaching direction. And a pair of gripping parts for holding the battery pack housed inside the electronic device.

[0010] Further, as a grip release means for separating the pair of grip portions against the urging force of the elastic body, a moving body supported so as to be movable in one direction between the pair of grip portions is provided. A widened portion whose width is gradually increased from the front to the rear in the moving direction is provided on the body, and when the moving body is moved when the battery pack is taken out, the widened portion pushes the pair of gripping portions outward. In this way, the battery pack is released from the restraint.

The grip release means is fixed to a battery cover mounted over the battery pack housed in the electronic device, and the operating portion provided on the outer portion of the electronic device is operated to operate the grip. When the battery cover is unlocked by operating the operation unit in conjunction with the battery cover fixing means for releasing the fixing, the grip release means is operated in conjunction with this to release the restraint of the battery pack.
