Description

本発明は、電池ホルダ、電池モジュール、及び電池ユニットに関し、特に複数個の電池を縦列接続した状態での取り扱いが容易になる電池ホルダ、電池モジュール、及び電池ユニットに関する。   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 facilitate handling in a state where a plurality of batteries are connected in cascade.

乾電池で必要な電圧を作るには、幾つかの乾電池を直列、並列に接続して必要な電圧を作るので、複数の乾電池を縦列に搭載することは日常的に行われる。このような電池搭載の取り扱いのしやすさを考慮して、ｎ個の乾電池を縦列に接続した縦列接続電池（又は、電池パック）が知られている。電池パックは例えば、シートで複数の電池を１つの集合体とした物である。   In order to produce the necessary voltage with dry batteries, several batteries are connected in series and in parallel to produce the necessary voltage, and therefore mounting a plurality of dry batteries in tandem is routinely performed. In consideration of the ease of handling of such battery mounting, a cascade connection battery (or battery pack) in which n dry batteries are connected in cascade is known. The battery pack is, for example, a product in which a plurality of batteries are integrated into one sheet.

例えば特許文献１では、単体の乾電池を縦直列に重ね合わせて接続し、縦直列に重ねた乾電池を熱収縮性の被覆体で一体に被覆することにより、乾電池を縦直列に接続して使用する多様な機器に対応して交換し易いものにすることが、提案されている。   For example, in Patent Document 1, a single dry battery is connected in a series-stacked manner, and the dry batteries stacked in a series in series are integrally covered with a heat-shrinkable covering so that the dry batteries are connected in a series in series. It has been proposed to make it easy to replace various devices.

特開２００２−２１６７２７号公報JP 2002-216727 A

しかしながら、上述した電池パックには以下のような課題がある。ｎ個の乾電池を縦列に接続した縦列接続電池（又は、電池パック）の場合、乾電池は一体形状（電池パック）にまとめられているので、交換する際は電池パックを交換することになる。電池パックが複数個の乾電池から成る場合、電池パック全体の電圧低下は劣化の激しい乾電池に左右される。本来は、その劣化の激しい乾電池のみ交換することが効率的である。   However, the battery pack described above has the following problems. In the case of cascade-connected batteries (or battery packs) in which n dry batteries are connected in cascade, since the dry batteries are integrated into a single shape (battery pack), the battery packs are replaced when they are replaced. When the battery pack is composed of a plurality of dry batteries, the voltage drop of the whole battery pack depends on the dry batteries which are severely deteriorated. Originally, it is efficient to replace only the dry batteries whose deterioration is severe.

また乾電池を１個ずつ、ｎ個多段接続している場合に、奥にある乾電池を交換しようとすると、交換作業に時間が掛かることがある。それは奥にある乾電池には手が届きづらく、外すことが困難なためである。   In addition, when n dry batteries are connected one by one in a multi-stage connection, if an attempt is made to replace a dry battery in the back, the replacement work may take time. This is because it is difficult to reach the battery in the back and it is difficult to remove it.

また交換する電池数が多い場合、乾電池の向き（電極の向き）を誤って搭載するなどのヒューマンエラーがある。その場合、目視での向きの確認と交換作業が必要であるが、上記と同様に外すことが困難な場合がある。このため交換する電池数が多い場合には、ヒューマンエラーを招きやすい。   In addition, when there are a large number of batteries to be replaced, there is a human error such as mounting the battery in the wrong direction (electrode direction). In that case, it is necessary to visually confirm the direction and replace it, but it may be difficult to remove it as described above. For this reason, when the number of batteries to be replaced is large, human error is likely to occur.

乾電池を交換する際、アクセス方向が限られている場合、例えば設置機器が固定されていたり、設置機器が重量物で移動ができない場合である。そのような場合、設置機器から電池搭載部を工具で外したり、何らかの方法で乾電池を着脱する必要がある。   When the battery is replaced, the access direction is limited, for example, when the installation device is fixed or the installation device cannot move due to heavy objects. In such a case, it is necessary to remove the battery mounting part from the installation device with a tool or to attach / detach the dry battery by some method.

本発明の目的は、複数の乾電池を搭載でき、複数の乾電池を一体として取り扱いがし易すく、また一部の乾電池だけを交換しやすい、電池ホルダ、電池モジュール、及び電池ユニットを提供することにある。   An object of the present invention is to provide a battery holder, a battery module, and a battery unit that can be equipped with a plurality of dry batteries, can be easily handled as a plurality of dry batteries, and can easily replace only some dry batteries. is there.

図４（ａ）〜図４（ｃ）を使って、電池モジュールの使用方法について説明する。図４（ａ）の電池モジュールは、連結部材３の接続部３ａとＬ型固定部１との接続箇所、連結部材３の薄肉部３ｂでそれぞれ回動することにより、伸縮できる。例えば図４（ｂ）〜図４（ｃ）の矢印方向に伸縮することができる。また、図４（ａ）の電池モジュールは、図４（ａ）のように折り畳まれた状態では、連結部材３とＬ型固定部１とがロックして、折り畳まれた状態を維持することができる。この折り畳まれた状態では、電池モジュールに搭載される複数の電池は、Ｌ型固定部１の開口部１ａ、連結部材３の開口部３ｄを通して端子同士の電気的接続が図られ、直列接続体を構成することができる。Ｌ型固定部１の開口部１ａ、連結部材３の開口部３ｄは、搭載される電池の電極を逃げるための開口である。   The usage method of a battery module is demonstrated using Fig.4 (a)-FIG.4 (c). The battery module of FIG. 4A can be expanded and contracted by rotating at the connection portion between the connecting portion 3a of the connecting member 3 and the L-shaped fixing portion 1 and the thin portion 3b of the connecting member 3, respectively. For example, it can be expanded and contracted in the direction of the arrow in FIGS. 4 (b) to 4 (c). Further, in the battery module shown in FIG. 4A, when the battery module is folded as shown in FIG. 4A, the connecting member 3 and the L-shaped fixing portion 1 are locked to maintain the folded state. it can. In this folded state, the plurality of batteries mounted on the battery module are electrically connected to each other through the opening 1a of the L-shaped fixing part 1 and the opening 3d of the connecting member 3, and the series connection body is formed. Can be configured. The opening 1a of the L-shaped fixing part 1 and the opening 3d of the connecting member 3 are openings for escaping the electrodes of the battery to be mounted.

図４（ａ）の電池ホルダでは、図４（ｂ）のように電池９を搭載することができ、別の電池ホルダを連結して図４（ｂ）の電池モジュールを構成することができる。図４（ｂ）の電池モジュールは、図４（ｃ）や図４（ｄ）に示すように、連結部材３で折り曲げることができる。電池モジュール全体としての取り扱いを考慮して、図４（ｄ）に示されるように、摘み部６を設けることもできる。摘み部６は、Ｌ型固定部１の開口部１ｂに係合させればよい。   In the battery holder of FIG. 4A, the battery 9 can be mounted as shown in FIG. 4B, and another battery holder can be connected to form the battery module of FIG. 4B. The battery module shown in FIG. 4B can be bent by the connecting member 3 as shown in FIGS. 4C and 4D. In consideration of handling of the battery module as a whole, a knob 6 can be provided as shown in FIG. The knob 6 may be engaged with the opening 1b of the L-shaped fixing part 1.

図５Ｂ（ａ）に、本実施形態の電池モジュールの一例として、電池を三つ直列接続した態様の電池モジュール１０を示す。図５Ｂ（ａ）の電池モジュール１０は摘み部６を含む。図５Ｂ（ｂ）では一例として、三つの電池９が搭載された電池モジュールを示している。図５Ｂ（ａ）の電池モジュール１０は電池９を搭載した状態で、図５Ｂ（ｄ）のように連結部材３を展開することができる。   FIG. 5B (a) shows a battery module 10 in a mode in which three batteries are connected in series as an example of the battery module of the present embodiment. The battery module 10 in FIG. 5B (a) includes a knob 6. FIG. 5B (b) shows a battery module on which three batteries 9 are mounted as an example. The battery module 10 of FIG. 5B (a) can expand | deploy the connection member 3 like FIG.5B (d) in the state which mounted the battery 9. FIG.

次に図５Ｂ（ａ）の電池モジュール１０を例に、本実施形態の電池モジュールの効果について説明する。図６に示すように、電池を三つ縦列接続した本実施形態の電池モジュールは、一つの連結部材３を展開し、連結部材３のＬ型固定部１との接続箇所を回動させて曲げることができる。これにより、背景技術のように、縦直列に重ねた乾電池を熱収縮性の被覆体で一体に被覆して構成された電池パックと比較して、狭小な空間へも電池モジュールを設置しやすい。具体的には、図６の距離Ｌ１だけ狭い空間であっても、本実施形態の電池モジュールでは設置作業やメンテナンス作業が可能である。また、接続箇所を展開したり折り曲げることにより、他の電池を電池モジュールから取り外すことなく、中央の電池を挿抜することができ、電池モジュールの搭載や交換の作業を容易に行うことができる。例えば、電池モジュール１０の折り畳まれた連結部材３を展開することによって、複数の電池を電池モジュール１０に装着した状態で、電池と電池との間に空間を形成することができる。これにより、三つ直列接続した電池のうち中央の電池だけを、上記空間を活用して交換することができ、作業が容易になる。   Next, the effect of the battery module of the present embodiment will be described using the battery module 10 of FIG. 5B (a) as an example. As shown in FIG. 6, the battery module of the present embodiment in which three batteries are connected in cascade expands one connecting member 3, and rotates and bends the connecting portion of the connecting member 3 with the L-shaped fixing portion 1. be able to. Thereby, as in the background art, it is easier to install the battery module in a narrow space as compared with a battery pack configured by integrally covering dry batteries stacked in series in series with a heat-shrinkable covering. Specifically, even in a space narrowed by a distance L1 in FIG. 6, the battery module of this embodiment can perform installation work and maintenance work. Further, by unfolding or bending the connection portion, the central battery can be inserted and removed without removing other batteries from the battery module, and the battery module can be easily mounted or replaced. For example, by expanding the connecting member 3 in which the battery module 10 is folded, a space can be formed between the batteries in a state where a plurality of batteries are mounted on the battery module 10. Accordingly, only the central battery among the three batteries connected in series can be replaced using the above space, and the work is facilitated.
