Abstract

PURPOSE:To store both a battery cell and a battery pack even in the case between the different battery cells. CONSTITUTION:A hollow-shpaed battery cell storing part 3 is provided in a casing 2. This storing part 3 is formed into a width considerably larger than a diameter of a battery cell of standard size to mount a retaining plate 7 through springs 8 to one side surface. The battery cell 9 and a battery pack 10 are press-fixed to the other side part of the storing part 3 by the retaining plate 7. An electrode 11 of the battery pack 10 is provided in a position brought into contact with a battery cell contact 5.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery storage structure capable of housing both battery cells and battery packs.

0002

[Prior Art] Conventionally, this type of battery storage method is as follows:
It is roughly divided into the following two types. That is, in the first method, a housing is provided with a storage part in which a battery pack is stored in the battery storage part, and a battery storage container having the same external shape and the same electrode position as the battery pack storage part is prepared. This is a method in which battery cells are stored through this storage container. Moreover, the second method is a method in which the battery pack has the same external shape and electrode position as the battery cells in which it is housed.

0003

The first method described above requires a special container for accommodating the battery cells. Furthermore, the second method has the disadvantage that it is not possible to accommodate a battery pack that is composed of battery cells having different diameters from those of the battery cells to be accommodated. The present invention has been made in view of the above-mentioned conventional drawbacks, and its purpose is to provide a battery storage structure that can store both battery cells and battery packs even between different types of battery cells. It is in.

0004

[Means for Solving the Problems] In order to achieve this object, the battery storage structure according to the present invention is formed in a housing and has a hollow battery storage structure having a width larger than the diameter of the battery cells to be stored. , a battery cell terminal provided in this battery storage part, and a presser plate that presses the battery side part from the side part of the battery storage part by means of a biasing means, and the battery stored in the battery storage part The electrode position of the pack is matched to the battery cell terminal.

[0005]

[Function] In the battery storage structure according to the present invention, the battery cells and the battery pack are fixed in a predetermined position in the battery storage part by the holding plate even when the diameters of the batteries are different, and in this position, the electrodes of the battery and the battery pack are Connected to the common contacts of the storage compartment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below with reference to the drawings. FIG. 1 is a plan cross-sectional view of a state in which standard-sized battery cells are housed, and FIG. 2 is a side cross-sectional view of the same. In these figures, 2 is a housing of the portable data input/output device, and a hollow battery storage section 3 is formed therein. The housing portion 3 is formed to be considerably larger than the diameter of the battery cell 9 in the width direction, and slightly larger than the diameter of the battery cell 9 in the height direction. A lid 4 is detachably attached to the opening side of the storage section 3, and the box of nine battery cells can be inserted into the storage section 3 by removing the lid 4. Further, a spring terminal 5 for the battery cell 9 is attached to the inner surface of the storage portion 3 in the opposite direction from the opening side. Furthermore, a presser plate 7 is disposed on one side of the storage portion 3 via a spring 8. Therefore, the housed battery cell 9 is pressed against the other side of the housing part 3 by the holding plate 7, its movement is restricted, and it is fixed so as to be connected to the spring contact 5. Note that the concave surface 7a formed on the side surface of the holding plate 7 is for regulating the movement of the battery 9 in the vertical direction.

FIG. 3 is a plan sectional view showing the state in which the battery pack 10 is housed in the storage section, and FIG. 4 is a side view of the same sectional view. 10
is a battery pack composed of battery cells of a different shape from the standard-sized battery cells 9 described above. When inserting this battery pack 10 into the storage section 3, the holding plate 7 moves against the spring 8 and presses and fixes the battery pack 10 against the other side of the storage section 3 in the same way as the battery cells 9. . When this battery pack 10 is stored in the storage section 3, the spring contact 5
An electrode 11 is provided at a position in contact with.

[0008]

Effects of the Invention As described in detail above, according to the battery storage structure according to the present invention, it is possible to press the side of the battery cell or the battery pack into the battery storage part to one side of the storage part. The holding plate to be fixed is biased by a spring, and the electrodes of the battery pack are placed in a position that matches the contact terminals for the battery cells in the compartment, so that a single battery compartment or a battery of a different size can be placed in the battery compartment. As a result, in the case of a battery-driven device such as a data input/output device, the battery can be used both as a cell and as a battery pack without having to prepare two types of battery storage sections.
