Description

一种镉镍蓄电池的封口结构
技术领域
本发明涉及镉镍蓄电池，特别是一种适用于镉镍蓄电池的封口结构。
背景技术
目前铁路车辆所用或其它固定式蓄电池均要求蓄电池外壳具有较高的耐冲击、振动，能够适应各种高、低温环境，因此蓄电池外壳的材料普遍为聚丙烯材料。在实际生产过程中，聚丙烯材料的蓄电池外壳必须采用热板焊焊接的方式进行封口操作。在热板焊封口过程中容易出现大面凹陷的现象，导致上下容易错位，影响蓄电池的封口效率和质量。
发明内容
本发明的目的是设计一种结构合理、使用效果好的镉镍蓄电池的封口结构。
本发明的技术方案是，一种镉镍蓄电池的封口结构，它包括电池壳体，其特征在于：在电池盖体的底部两侧设有卡合凸板，在卡合凸板的底部设有“V”型的凸起，在电池壳体的两侧设有与卡合凸板相配的卡槽，实现了电池盖与电池壳的嵌套配合，再对电池盖和电池壳体进行焊接，使得卡合凸板的“V”型的突起融化与电池盖粘接为一体。所述的焊接是超声波焊接。
本发明的目的：
1、彻底解决聚丙烯外壳焊接后错位、漏气、外观质量差的情况，电池上盖与电池壳为嵌套式结构，焊接后电池外壳将电池盖完全包覆，电池盖与电池壳外壁平齐。
2、该封口结构采用超声波焊接方式进行焊接，焊接速度和质量远远高于热板焊焊接方式，易操作，效率高，可一定程度上降低成本。
附图说明；
图1是本发明的结构示意图。
具体实施方式：
本发明的具体实施例是：
一种镉镍蓄电池的封口结构，它包括电池壳体5，在电池盖体1的底部两侧设有卡合凸板2，在卡合凸板的底部设有“V”型的凸起4，在电池壳体的两侧设有与卡合凸板相配的卡槽3，实现了电池盖与电池壳的嵌套配合，再对电池盖和电池壳体进行焊接，使得卡合凸板的“V”型的凸起融化与电池盖粘接为一体；本发明述的焊接方式是超声波焊接。
本设计在电池盖的底部卡合凸板的底部设计一个“V”型的凸起，电池盖与电池壳为嵌套配合，焊接时，电池盖“倒V”型的突起融化与电池盖粘接为一体。确保电池壳、盖上下的对接定位，杜绝错位情况，可以提高封口质量和效率；同时该方案优选的采用是超声波焊接方式，相对于热板焊接的方式，本设计快捷、效率高，可一定程度上降低成本。
上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举，而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之内。
