これらの図を参照して、蓄電池用トレー１は、側部２０と底部３０とを有する。側部２０は、長手側側壁２１と短手側側壁２２とを有する。長手側側壁２１は、蓄電池用トレー１の長手方向に延在する。長手側側壁２１の内周面側には、底部３０から上方に向かって延在するリブ２１ａが複数本設けられる。長手側側壁２１には薄肉部２１ｂと厚肉部２１ｃが設けられる。薄肉部２１ｂは蓄電池が膨張した場合に蓄電池と長手側側壁２１との接触を防止するために設けられる。厚肉部２１ｃは、薄肉部２１ｂよりも肉厚に設けられてリブ２１ａを保持している。短手側側壁２２にはリブ２２ａが設けられており、リブ２２ａは蓄電池５０に当接する。   With reference to these drawings, the storage battery tray 1 has a side portion 20 and a bottom portion 30. The side part 20 has a long side wall 21 and a short side wall 22. The longitudinal side wall 21 extends in the longitudinal direction of the storage battery tray 1. A plurality of ribs 21 a extending upward from the bottom 30 are provided on the inner peripheral surface side of the longitudinal side wall 21. The long side wall 21 is provided with a thin portion 21b and a thick portion 21c. The thin portion 21b is provided to prevent contact between the storage battery and the longitudinal side wall 21 when the storage battery expands. The thick part 21c is provided thicker than the thin part 21b and holds the rib 21a. A rib 22 a is provided on the short side wall 22, and the rib 22 a contacts the storage battery 50.

底部３０は中央底部３５と、中央底部３５よりも深さの浅い外側底部３６とを有する。このように底部３０を２段構造とすることで、底部３０の強度を向上させることができる。底部３０には、複数の凸部３１，３３が設けられており、これらの凸部３１，３３以外の部分が、電解液を溜める空間３２，３４とされている。   The bottom 30 has a central bottom 35 and an outer bottom 36 that is shallower than the central bottom 35. Thus, the intensity | strength of the bottom part 30 can be improved by making the bottom part 30 into a 2 step | paragraph structure. The bottom portion 30 is provided with a plurality of convex portions 31 and 33, and portions other than the convex portions 31 and 33 are spaces 32 and 34 in which the electrolytic solution is stored.

蓄電池用トレー１は、さらにフランジ部４０を有する。フランジ部４０は、短手側側壁２２側に設けられており、フランジ部４０には貫通孔４１が形成されている。フランジ部４０は蓄電池用トレー１を台に固定するための部分であり、厚肉に構成される。   The storage battery tray 1 further has a flange portion 40. The flange portion 40 is provided on the short side wall 22 side, and a through hole 41 is formed in the flange portion 40. The flange portion 40 is a portion for fixing the storage battery tray 1 to the base, and is configured to be thick.

図１０は、実施の形態に従った蓄電池用トレーに蓄電池を収納した使用状態を示す斜視図である。図１１は、押さえ金具と、蓄電池と、実施の形態に従った蓄電池用トレーとの分解斜視図である。図１２は、実施の形態に従った蓄電池用トレーに蓄電池を収納した使用状態を示す横断面図である。図１３は、実施の形態に従った蓄電池用トレーに蓄電池を収納した使用状態を示す縦断面図である。 (2) Usage State of Storage Battery Tray 1 FIG. 10 is a perspective view showing a usage state in which the storage battery is stored in the storage battery tray according to the embodiment. FIG. 11 is an exploded perspective view of the presser fitting, the storage battery, and the storage battery tray according to the embodiment. FIG. 12 is a cross-sectional view showing a use state in which the storage battery is stored in the storage battery tray according to the embodiment. FIG. 13: is a longitudinal cross-sectional view which shows the use condition which accommodated the storage battery in the tray for storage batteries according to embodiment.

これらの図を参照して、蓄電池用トレー１の使用時には、蓄電池用トレー１に蓄電池５０が嵌め合わせられる。この例では３つの蓄電池５０が１つの蓄電池用トレー１に嵌め合わせられる例を示しているが、１つの蓄電池用トレー１にさらに多くの、または少ない蓄電池５０が嵌め合わせられてもよい。蓄電池５０は長手方向と有し蓄電池用トレー１の長手方向と蓄電池５０の長手方向とが一致するように蓄電池５０は蓄電池用トレー１に嵌め合わせられる。蓄電池５０は押さえ金具５１により押圧されており、押さえ金具５１はボルト５２によりフランジ部４０に固定される。   With reference to these drawings, when the storage battery tray 1 is used, the storage battery 50 is fitted into the storage battery tray 1. In this example, three storage batteries 50 are fitted into one storage battery tray 1, but more or fewer storage batteries 50 may be fitted into one storage battery tray 1. The storage battery 50 is fitted in the storage battery tray 1 so that the storage battery 50 has a longitudinal direction and the longitudinal direction of the storage battery tray 1 matches the longitudinal direction of the storage battery 50. The storage battery 50 is pressed by a pressing metal 51, and the pressing metal 51 is fixed to the flange portion 40 by a bolt 52.

蓄電池用トレー１は難燃材、たとえば、ＵＬ９４Ｖ−０規格を通過するものとすることが好ましい。さらに、蓄電池用トレー１は高強度・耐酸性材料により構成される。蓄電池用トレー１の下部には、電解液を溜める空間３２，３４を設けており、蓄電池用トレー１内に、蓄電池５０から漏れた電解液を溜めることができる。蓄電池５０の膨張によって蓄電池用トレー１が割れることを防止するために、蓄電池５０の膨張分の余裕を蓄電池用トレー１に設け、蓄電池５０の四隅をリブ２１ａ，２２ａで固定する形状としている。膨張分の余裕のスペースは、蓄電池５０の上部で液漏れが発生した場合の下まで液が流れるためのスペースを兼ねている。このような構成とすることで、絶縁シートで導電部分を包んだり、折ったりする手間がなくなるため、組立作業性が向上する。蓄電池用トレー１は成型品のため、大量生産に適しており、コストを削減することが可能となる。   The storage battery tray 1 preferably passes a flame retardant material, for example, UL94V-0 standard. Furthermore, the storage battery tray 1 is made of a high-strength, acid-resistant material. Spaces 32 and 34 for storing the electrolytic solution are provided below the storage battery tray 1, and the electrolytic solution leaking from the storage battery 50 can be stored in the storage battery tray 1. In order to prevent the storage battery tray 1 from cracking due to the expansion of the storage battery 50, the storage battery tray 1 is provided with a margin for expansion of the storage battery 50, and the four corners of the storage battery 50 are fixed by the ribs 21a and 22a. The space for the expansion is also used as a space for the liquid to flow to the bottom when a liquid leak occurs in the upper part of the storage battery 50. With such a configuration, there is no need to wrap or fold the conductive portion with the insulating sheet, so that the assembly workability is improved. Since the storage battery tray 1 is a molded product, it is suitable for mass production, and the cost can be reduced.

（３）蓄電池５０の膨張
図１４は、実施の形態に従った蓄電池用トレーに蓄電池を収納した使用状態を示す平面図である。図１５は、実施の形態に従った蓄電池用トレーに蓄電池を収納して蓄電池が膨張した使用状態を示す平面図である。 (3) Expansion of storage battery 50 FIG. 14 is a plan view showing a use state in which the storage battery is stored in the storage battery tray according to the embodiment. FIG. 15 is a plan view showing a use state in which the storage battery is expanded by storing the storage battery in the storage battery tray according to the embodiment.

これらの図を参照して、隣接する蓄電池５０間の隙間をＷ１、蓄電池５０と短手側側壁２２との間の隙間をＷ２、蓄電池５０と長手側側壁２１との間の隙間をＷ３とした場合に、Ｗ１が、Ｗ２およびＷ３よりも大きい。蓄電池５０の寿命末期には、蓄電池５０は、図１５中の点線で示すように、膨張する場合がある。この場合でも、上記の隙間が設けられているため、蓄電池用トレー１が割れることを防止できる。さらに、隙間が存在することで蓄電池５０の上部から電解液が漏れた場合であっても、この隙間を経由して下部へ電解液が流れ込んで蓄電池用トレー１内に電解液を保持することが可能である。蓄電池５０が膨張しやすい方向の隙間を大きくすることができる。   Referring to these drawings, the gap between adjacent storage batteries 50 is W1, the gap between storage battery 50 and short side wall 22 is W2, and the gap between storage battery 50 and long side wall 21 is W3. In some cases, W1 is greater than W2 and W3. At the end of the life of the storage battery 50, the storage battery 50 may expand as shown by the dotted line in FIG. Even in this case, since the gap is provided, the storage battery tray 1 can be prevented from cracking. Further, even when the electrolyte leaks from the upper part of the storage battery 50 due to the presence of the gap, the electrolyte can flow into the lower part via the gap to hold the electrolyte in the storage battery tray 1. Is possible. The gap in the direction in which the storage battery 50 easily expands can be increased.

つまり、蓄電池用トレー１は、複数の蓄電池５０を収納可能な、絶縁材により構成される蓄電池用トレー１であって、蓄電池用トレー１の底には蓄電池５０を支持する凸部３１，３３と電解液を溜める空間３２，３４が設けられ、複数の蓄電池５０の各々は位置決め部材としてのリブ２１ａ，２２ａと接触して位置決めされると共に、複数の蓄電池５０間には隙間が設けられており、蓄電池５０は膨張することが可能である。各々の蓄電池５０は、少なくとも４か所でリブに当接することで位置決めされる。複数の蓄電池５０は各々の蓄電池５０の長手方向に沿って並んで配置される。蓄電池用トレー１は難燃性材料により構成される。蓄電池用トレー１は、長手側側壁２１と短手側側壁２２とを有し、長手側側壁２１には薄肉部２１ｂと厚肉部２１ｃが設けられ、厚肉部２１ｃにリブ２１ａが接続されている。蓄電池用トレー１の底部３０は、中央底部３５と、中央底部３５よりも深さの浅い外側底部３６とを有する。   That is, the storage battery tray 1 is a storage battery tray 1 made of an insulating material that can store a plurality of storage batteries 50, and the bottoms of the storage battery tray 1 have convex portions 31 and 33 that support the storage battery 50. Spaces 32 and 34 for storing the electrolytic solution are provided, and each of the plurality of storage batteries 50 is positioned in contact with ribs 21a and 22a as positioning members, and a gap is provided between the plurality of storage batteries 50. The storage battery 50 can expand. Each storage battery 50 is positioned by contacting the ribs at at least four locations. The plurality of storage batteries 50 are arranged side by side along the longitudinal direction of each storage battery 50. The storage battery tray 1 is made of a flame retardant material. The storage battery tray 1 has a long side wall 21 and a short side wall 22. The long side wall 21 is provided with a thin portion 21b and a thick portion 21c, and a rib 21a is connected to the thick portion 21c. Yes. The bottom 30 of the storage battery tray 1 has a center bottom 35 and an outer bottom 36 that is shallower than the center bottom 35.
