Abstract

本实用新型公开了一种锂离子电池的防爆膜组合件，本实用新型涉及电池防爆技术，本实用新型的目的是提供一种便于安装、更换和适用范围广的一种锂离子电池的防爆膜组合件。本实用新型的技术方案是，包括防爆膜，环形塑料体内的下部固连有防爆膜。本实用新型用于锂离子电池防爆。

Description

一种锂离子电池的防爆膜组合件
技术领域：
本实用新型涉及一种电池防爆技术，特别是一种锂离子电池的防爆膜组合件。
背景技术：
锂离子动力电池或者超级电容，在使用过程中因内部会产生大量的气体，在达到极限时不能释放就会导致爆炸，而现有防爆膜的结构多为焊接或者其他固接结构，虽然避免电池爆炸，但防爆膜一旦破裂而不能更换，造成电池报废。
发明内容：
本实用新型的目的是提供一种便于安装、更换和适用范围广的一种锂离子电池的防爆膜组合件。本实用新型的技术方案是，包括防爆膜，其特征在于：环形塑料体内的下部固连有防爆膜。所述防爆膜，其外沿与环形塑料体相接触部分为波纹或外端为L形。本实用新型与现有技术比较具有安装、更换方便且使用范围广的显著优点。
附图说明：
附图是本实用新型锂离子电池的防爆膜组合件。
具体实施方式：
为了解决现有电池防爆膜在爆破后不能更换的缺限，本实用新型采用了将防爆膜注塑在环形塑料体中形成防爆膜组合件。防爆膜2处在环形塑料体1的部分设有波纹或者其外缘为折弯，以增强其与环形塑料体间的牢固性。作为实施此防爆膜组合件的一个实施例：在锂电池的盖板5上设有一台阶孔4，此台阶孔与防爆组合件相配，在台阶孔的上部为螺纹，下端面与防爆膜组合件的下端面相对。
本实用新型的防爆和更换方法是，将预制的内设防爆膜(铜箔或铝箱)的防爆膜组合件置于盖板的螺纹台阶孔中，用管螺纹体3将防爆组合件固定在盖板上，当更换防爆膜时，松开螺纹管，即可更换，十分方便和快捷。

Claims (2)

1.一种锂离子电池的防爆膜组合件，包括防爆膜，其特征在于：环形塑料体内的下部固连有防爆膜。
2.如权利要求1所述的一种锂离子电池的防爆膜组合件，其特征在于：所述防爆膜，其外沿与环形塑料体相接触部分为波纹或外端为L形。
