産業上の利用分野
本発明は、密閉式鉛蓄電池の改良に関するものであり、
とくに自動車用鉛蓄電池などのように数１０ムｈ以上の
比較的容量が大きい密閉式鉛蓄電池に関するものである
。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to improvements in sealed lead-acid batteries.
In particular, it relates to sealed lead-acid batteries with a relatively large capacity of several tens of muh or more, such as lead-acid batteries for automobiles.
従来の技術

し、負極板を気相と接触させる構造を採っている。The typical sealed method for conventional lead-acid batteries is the gas absorption method at the negative electrode. This is a method in which oxygen gas generated from the positive electrode at the end of charging is reacted with the negative electrode plate to suppress a decrease in electrolyte solution due to gas generation during overcharging. For this reason, a structure is adopted in which the electrolytic solution is fixed in a gel state by two vanes or by being absorbed by a mat-like separator, and the negative electrode plate is brought into contact with the gas phase.
ところで、密閉式鉛蓄電池では、電池内部の気圧が高く

し、このような圧力の上昇は電池内部に何か異常が発生
した場合に起こるものである。通常の使用状態において
は発生した酸素ガスは負極板に吸収されてしまうので減
圧状態になっている。By the way, in sealed lead-acid batteries, consideration has been given to safety by adopting a structure in which gas is discharged from a safety valve when the internal pressure of the battery becomes high. However, such a pressure increase occurs when something abnormal occurs inside the battery. Under normal usage conditions, the generated oxygen gas is absorbed by the negative electrode plate, resulting in a reduced pressure state.
発明が解決しようとする問題点
そのため、減圧状態が大きくなると、電槽が外気から押
されてへこみが生じる心配がある。Problems to be Solved by the Invention Therefore, if the reduced pressure becomes large, there is a fear that the battery case will be pushed by the outside air and dented.
従来、密閉式鉛蓄電池の一般的な用途は、ビデオ用、携
帯用掃除機等の電源であり、数ムｈの容量を持った比較
的小形の密閉式鉛蓄電池が実用化されていたつ近年その
用途も拡大され、非常用等の電源あるいは自動車用など
にも要望されてきた。Traditionally, sealed lead-acid batteries have been commonly used as power sources for video devices, portable vacuum cleaners, etc., and in recent years, relatively small sealed lead-acid batteries with a capacity of several μh have been put into practical use. Its uses have also expanded, and it is now being requested as an emergency power source and for automobiles.
減圧による電槽の変形（へこみ）に対し、小形３ベーノ
の電池では電槽の面積も小さく、電槽外壁の厚みを若干
厚くする事で対応できていた。しかし、電池が大きくな
るにしだがって、厚みだけで対応すると非常に厚くカリ
過ぎて、工業的に適さなくなってきた。そこで、電槽材
質などの検討もなされているが、経済性等を考えると未
だ、十分に満足する方法はない。The deformation (denting) of the battery case due to depressurization can be counteracted by making the outer wall of the battery case slightly thicker, since the area of the battery case is small in small 3-benzo batteries. However, as batteries have grown larger, relying only on thickness has become too thick and thick, making it unsuitable for industrial use. Therefore, studies have been made on the material of the battery case, but there is still no method that is fully satisfactory in terms of economic efficiency.
そこで、本発明は電槽外壁面の構造を改良することによ

わり特性状もバラツキが大きくなり、寿命低下の原因に
もなる。Therefore, the present invention suppresses deformation of a sealed lead acid battery by improving the structure of the outer wall surface of the battery case. This deformation of the battery case is not just a cosmetic problem, but if the battery case is deformed and dented, and if left in that state for a long period of time, the strength of the battery case will decrease, increasing the risk of breakage, and increasing safety. It is also undesirable in terms of sex. Furthermore, if the battery case is dented, bulged, or significantly deformed, the group pressure of the electrode plates inside the battery will change, leading to greater variations in characteristics, which may also cause a reduction in service life.
そこで、本発明は電槽の変形を抑制することにより、安
全性、特性の両面から信頼性を高めるものである。Therefore, the present invention improves reliability in terms of both safety and characteristics by suppressing deformation of the battery case.
問題点を解決するだめの手段
本発明は、電槽の短側面の内壁に高さ方向に延びるリプ
を設け、かつ電槽の短側面の外壁にこのリプと直角に交
差するリプを極板群よりも高い位置に設けたものである
。Means for Solving the Problems The present invention provides a lip extending in the height direction on the inner wall of the short side of the battery case, and a lip that intersects this lip at right angles to the outer wall of the short side of the battery case as a group of electrode plates. It is placed at a higher position.

性能のバラツキを抑制して信頼性を高めるものである。Function: With this configuration, it is possible to improve safety by suppressing the deformation of the battery case and preventing it from becoming rigid due to deformation, thereby increasing the strength of the battery case. This is to suppress this and increase reliability.
