Description

The present invention relates to a battery holder, a battery module, and a battery unit, and more particularly to a battery holder, a battery module, and a battery unit that can be easily handled in a state where a plurality of batteries are connected in a column.

In order to create the required voltage with dry batteries, several dry batteries are connected in series or in parallel to create the required voltage, so it is common practice to mount multiple dry batteries in tandem. Considering the ease of handling such a battery-mounted battery, a column-connected battery (or battery pack) in which n dry batteries are connected in a column is known. A battery pack is, for example, a sheet in which a plurality of batteries are assembled into one.

For example, in Patent Document 1, single dry batteries are stacked in vertical series and connected, and the dry batteries stacked in vertical series are integrally coated with a heat-shrinkable coating body, so that the dry batteries are connected and used in vertical series. It has been proposed to make it easy to replace for various devices.

JP-A-2002-216727

However, the above-mentioned battery pack has the following problems. In the case of a column-connected battery (or battery pack) in which n dry batteries are connected in a column, the dry batteries are grouped together in an integral shape (battery pack), so that the battery pack must be replaced when replacing. When the battery pack consists of a plurality of dry batteries, the voltage drop of the entire battery pack depends on the dry batteries that are severely deteriorated. Originally, it is efficient to replace only the dry battery whose deterioration is severe.

Further, when n dry batteries are connected one by one in multiple stages, if the dry batteries in the back are to be replaced, the replacement work may take time. This is because the batteries in the back are hard to reach and difficult to remove.

In addition, when the number of batteries to be replaced is large, there is a human error such as incorrect mounting of the dry battery orientation (electrode orientation). In that case, it is necessary to visually confirm the orientation and replace it, but it may be difficult to remove it as described above. Therefore, when the number of batteries to be replaced is large, human error is likely to occur.

When replacing the dry battery, the access direction is limited, for example, the installed equipment is fixed or the installed equipment is heavy and cannot be moved. In such a case, it is necessary to remove the battery mounting part from the installed equipment with a tool or to attach / detach the dry battery by some method.

An object of the present invention is to provide a battery holder, a battery module, and a battery unit capable of mounting a plurality of dry batteries, making it easy to handle the plurality of dry batteries as a unit, and easily replacing only some of the dry batteries. is there.

Generally, when accessing the battery pack installed inside the columnar member 300 through the opening 300a to the columnar member 300, the length of a single battery constituting the battery pack × the length of the number of columns Work space is required. Therefore, the opening 300a of the columnar member 300 needs to be wide by the distance L2 shown in FIG. 11D. Further, in order to access the battery pack installed inside the columnar member 300, a corresponding work space is required.

On the other hand, in the battery unit 100 accommodating the battery module 10 of the present embodiment, as described in the battery module of FIG. 6, one connecting member 3 is developed, and the connecting member 3 and the L-shaped fixing portion 1 are connected to each other. The connection point can be bent. More specifically, the battery module 10 is pulled up from the battery unit 100 installed inside the columnar member 300, and as shown in FIG. 12A, one connecting member 3 is developed, and the connecting members 3 and L are developed. The connection point with the mold fixing portion 1 can be bent. As a result, if there is an opening 300b having a width corresponding to the length of the single battery + the length corresponding to the diameter of the battery, the battery module of the battery unit of the present embodiment can perform installation work and maintenance work. As shown in FIG. 12B, the battery module of the battery unit installed inside the columnar member 300 can be accessed even from the opening 300b narrower than the opening 300a by a distance L3. According to the battery unit and the battery module of the present embodiment, the battery can be inserted and removed in a narrow space.

In the battery unit and the battery module of the present embodiment, for example, when the battery modules are housed in a plurality of rows, the battery module in the back of the device can be accessed from a narrow opening and easily inserted and removed. Can be done.

In the battery pack of the background technology, when mounting a battery pack composed of a combination of n batteries, it is necessary to provide a work space for inserting and removing n battery packs. On the other hand, in the battery unit and the battery module of the present embodiment, one connecting member 3 can be unfolded and the connecting portion between the connecting member 3 and the L-shaped fixing portion 1 can be bent. As a result, if there is an opening 300b corresponding to the length of the single battery + the length corresponding to the diameter of the battery, the battery module of the battery unit of the present embodiment can perform installation work and maintenance work.
