作为进一步的改进,所述泄压阀装置中包括有一本体区域及一薄化区域,所述薄化区域包括复数条凹陷形成的所述压痕,复数所述压痕相交于一位于所述薄化区域上形成一所述破裂点,复数所述压痕等角度间隔地从所述破裂点向外延伸。
作为进一步的改进,第二盖体中还具有一容置空间,所述容置空间中开设有一第二开口,所述容置空间中还设有一电源连接器,所述电源连接器露出于所述第二开口。

附图说明

图2为图1所示的立体分解图。
图3为本实用新型具有泄压阀装置的电池模组的泄压阀装置之立体图。
图4为图1中IV-IV线剖面图。
图5为第图5中V圈之放大图。
具体实施方式
为详细说明本实用新型的技术内容、构造特征、所实现的目的和功效,以下结合具体实施例并配合附图予以详细说明。
请参阅图1、图2及图5,本实用新型具有泄压阀装置的电池模组100包括一多串并联电池模组1、一壳体2、一第一盖体3、至少一泄压阀装置4及一第二盖体5。
所述多串并联电池模组1包括复数组并联的复数电池11,以及将复数电池11固定住的支架12。本实施例中,以六个电池11为一组,共有十四组电池组,每一电池组的正负极交错设置。
所述壳体2包覆住多串并联电池模组1。
第一盖体3装设于壳体2的一端,第一盖体3开设有至少一第一开口31。第二盖体5装设于壳体2的另一端。
请参阅图2至图5,泄压阀装置4装设于第一开口31中,泄压阀装置4中包括有一本体区域41及一薄化区域42,该薄化区域42的厚度小于本体区域41的厚度。薄化区域42包括复数条凹陷形成的压痕421,复数压痕421相交于一位于薄化区域42上形成一破裂点422,复数压痕421等角度间隔地从破裂点422向外延伸。本实施例中,设有四个压痕421,但实施上该复数压痕421的数量不以本实施例为限,只要能相交于破裂点22上即可。
所述泄压阀装置4为小型薄片单独射出成型后埋射成型到塑胶主本体的设计,由于塑胶厚度不一,如此单独射出成型在埋设的方法,可以改善单一塑胶本体厚度不一时,射出成型困难的情形。
本实用新型具有泄压阀装置的电池模组100使用时,当多串并联电池模组1内部有气体压力时,由于薄化区域42会于厚度较薄的复数压痕421处产生应力集中的现象,且上述应力会顺着复数压痕421汇聚集中于破裂点422,使得破裂点422处会受到最大的应力,即薄化区域42上最脆弱的部位会位于破裂点422处。一旦多串并联电池模组1内部的气体压力超过一定阀值时,薄化区域42会先于破裂点422产生裂缝,并沿着复数压痕421向外裂开以释出气体,由于复数压痕421呈放射状裂开,因此不会有物件分离而射伤使用者的风险。
此外,从一点放射状渐趋裂开的方式,能先由从小裂缝开始逐渐释出高压气体,以逐渐降低内部压力,接着在该等压痕421继续向外裂开时,由于内部气体已经有部分释出,所以内部气体压力较低,使得气体释出的速度也能获得减缓,借以避免高压气体大量释出而发出爆裂声。
请参阅图1、图2及图4,第一盖体3还连接有一把手6,把手6具有两向下凸伸形成的第一连接部61,第一盖体3的外表面上设有两对应第一连接部61而设的第二连接部32,第一开口31位于两第二连接部61之间,即泄压阀装置4设置于两第二连接部61之间。具体地,第一开口设在两第二连接部61间的中间位置,即泄压阀装置4设置于两第二连接部61之间的中间位置。
第二盖体5中还具有一容置空间51,容置空间51中开设有一第二开口52,容置空间51中还设有一电源连接器53,电源连接器53露出于第二开口52,可以与外部进行电连接,以将多串并联电池模组1中的电力向外输出。
承上所述,藉由在第一盖体3上设置泄压阀装置4,使得多串并联电池模组1中产生的气压能从中排出,避免气体堆积在电池组中,以防止电池组中电池11的损坏。
