Abstract

PROBLEM TO BE SOLVED: To provide a battery storage structure for a battery pack capable of reliably storing plural batteries with a simple structure without rocking them and also reducing the weight of the battery pack. SOLUTION: This battery pack body 1 is formed into a box with a bottom having side walls 2, 3, 4, 5 surrounding it. Its opening part is covered with a lid which is not shown in the Fig. The opening part of the battery pack body 1 is rectangular, and in this case two batteries are stored. A stabilizing block 6 positioning between the two batteries is formed integrally with the battery pack body 1 on the bottom of the battery pack body 1. The stabilizing block 6 has a trapezoidal cross section, and its slant surface abuts on the side surface of the battery. That is, the slant surface of the stabilizing block 6 is formed so as to well fit to the side surface of the battery. A slight force is applied to the side surface of the battery from the stabilizing block by covering the battery with the lid. Accordingly the battery does not move.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery accommodating structure for a battery pack which is attached to, for example, an electronic device main body and supplies power to the electronic device main body.

[0002]

2. Description of the Related Art In recent years, portable electronic devices such as portable telephones have been desired by users as a whole to be thin, lightweight, and compact, and these tendencies have been further strengthened. Such an electronic device employs a plastic battery pack that is easily detachable from the electronic device. In this battery pack, a charge type battery is built in together with a safety circuit. The battery is accommodated in the battery pack according to the specification, but when a plurality of cylindrical batteries are employed, the accommodated batteries need to be semi-fixedly accommodated in the battery pack.

That is, it is necessary to prevent the battery from causing dimensional play in the battery pack. Conventionally, for this purpose, a receiving structure that conforms to the appearance of the battery is integrally formed with the battery pack so that the shape inside the battery pack is integrated with the battery pack, and a plurality of cylindrical batteries are juxtaposed to this. When the structure is adopted, there is a disadvantage that the structure of the battery pack itself becomes complicated or the weight as a whole increases.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a battery pack structure for a battery pack which can store a plurality of batteries with a simple structure without rocking and can reduce the weight of the battery pack. Is what you do.

[0005]

Means for solving the above problems include a box-shaped battery pack main body having a structure in which at least a battery is housed and which can be attached to an electronic apparatus main body, and a bottom portion of the battery pack main body. And a battery stabilizing base formed between the batteries.

[0006]

When the above-mentioned stabilizer is provided in the center of the battery pack body and a plurality of cylindrical batteries are stored on the left and right sides, the tip of the stabilizer abuts on the periphery of the battery so that it can be firmly attached to the battery pack lid. The battery does not swing right and left because of the pressing, and the weight can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings, FIGS. 1 and 2. FIG. 1 shows a plastic battery pack body 1 having an opening. The battery B is housed inside as shown in FIG. That is, the battery pack main body 1 is a box shape with a bottom, and its periphery is constituted by side walls 2, 3, 4, and 5.
This opened portion is covered with a lid (not shown). The battery pack body 1 is rectangular at the opening, and two batteries B are stored in this case.

A stabilizer 6 is formed between the two batteries B and is formed integrally with the battery pack main body 1 at the bottom of the battery pack main body 1. The stabilizer 6 has a trapezoidal cross section,
The trapezoidal oblique surface is provided on the side of battery B. That is, the oblique surface of the stabilizer 6 is adapted to the side surface of the battery B. Then, a slight force is applied to the side surface of the battery by covering the battery B with the lid 7 from the stabilizer 6. Therefore, the battery B does not swing.

The stabilizer 6 may be provided at the center of the bottom of the battery pack body 1 and need not be elongated in the longitudinal direction of the battery pack body 1. Therefore, the weight of the stabilizer 6 can be reduced because it is small. In the above embodiment, the stabilizer 6 is provided at the bottom of the battery pack body. However, the present invention is not limited to this.
May be formed. In addition, the length of the stabilizer 6 can be freely set, and may be formed in the entire longitudinal direction.

[0010]

As described above, according to the present invention, a box-shaped battery pack main body having a structure in which at least a battery is housed and which can be attached to an electronic device main body, and a bottom portion of the battery pack main body and between the batteries are provided. Since the battery stabilizing base is formed so as to be positioned, the weight can be reduced, the structure is simple and the battery is pressed securely, and the battery does not swing in the battery pack body.
