Description

防爆电池
技术领域
本发明涉及电池技术领域,尤其涉及防爆电池。
背景技术
近日,浙江工商局通报了对36款手机的抽查结果,其中合格率仅为25%,大多数手机都存在电池易发生爆炸的隐患,其原因在于手机内的电池可能因短路生热,电池点的气体无处宣泄而发生爆炸,传统手机内的锂电池一般将电池原材的正负极与电池壳体上的触片连接,电池壳体上具有一个抽气孔,在电池原材装入电池壳体后通过抽气孔将电池壳体与电池原材之间的间隙抽真空注入物质,然后再将抽气孔密封。这种电池如果在电池短路时,电池受热原材释放出大量气体,这些气体无法排泄到电池的外部,因此这种电池很容易发生爆炸,影响使用者的生命安全。
发明内容
本发明针对现有技术不足,提供防爆电池,此种防爆电池能够降低电池爆炸的可能性,提高电池使用的安全性。
为了解决上述技术问题,本发明通过下述技术方案得以解决:防爆电池,包括壳体,所述壳体上设置有两个触片,所述壳体内设置有电池原材,所述电池原材的正负极分别连接两个所述触片,所述壳体上设置抽气孔,所述抽气孔内过盈设置有软性塞子,所述塞子一侧为卡盘,所述卡盘一侧贴合所述壳体另一侧贴合所述电池原材,所述卡盘上设置有气道,所述塞子侧壁上设置有气孔,所述气道与所述气孔相通,所述气孔到所述卡盘的距离小于所述壳体的壁厚。设置抽气孔用于将壳体与电池原材之间的空隙抽成真空状态,然后在壳体和电池原材之间注入物质,正常情况下塞子通过过盈配合将抽气孔堵住,当电池短路或碰撞时,壳体内部产生大量气体,壳体内部气压增大会将塞子往外压,当塞子往外压时气孔就会与壳体外部相通,壳体内的气体就会通过气道流出到壳体外部从而壳体内部的气压降低,当气压降低后,由于塞子是软性材料,因此塞子又回复到起初的位置将抽气孔堵住,这样就有效防止了电池爆炸。
上述技术方案中,优选的,所述壳体包括相互配合形成密闭空间的上壳体和下壳体。为了方便加工,将壳体分成上壳体和下壳体。
本发明与现有技术相比,具有如下有益效果:本发明设置抽气孔用于将壳体与电池原材之间的空隙抽成真空状态,然后在壳体和电池原材之间注入物质,正常情况下塞子通过过盈配合将抽气孔堵住,当电池短路或碰撞时,壳体内部产生大量气体,壳体内部气压增大会将塞子往外压,当塞子往外压时气孔就会与壳体外部相通,壳体内的气体就会通过气道流出到壳体外部从而壳体内部的气压降低,当气压降低后塞子又回复到起初的位置将抽气孔堵住,这样就有效防止了电池爆炸。
附图说明
图1为本发明实施例的结构示意图。
图2为本发明实施例中塞子的结构示意图。
具体实施方式
下面结合附图与具体实施方式对本发明作进一步详细描述:参见图1至图2,防爆电池,包括壳体1,所述壳体1上设置有两个触片,所述壳体1内设置有电池原材2,所述电池原材2的正负极分别连接两个所述触片,所述壳体1上设置抽气孔3,所述抽气孔3内过盈设置有软性塞子4,所述塞子4一侧为卡盘41另一侧为圆柱体,所述卡盘41一侧贴合所述壳体1另一侧贴合所述电池原材2,所述卡盘41上设置有气道411,所述塞子4侧壁上设置有气孔42,所述气道411与所述气孔42相通,所述气孔42到所述卡盘41的距离小于所述壳体1的壁厚,为了方便加工,所述壳体1包括相互配合形成密闭空间的上壳体11和下壳体12。
设置抽气孔3用于将壳体1与电池原材2之间的空隙抽成真空状态,然后在壳体1和电池原材2之间注入物质,正常情况下塞子4通过过盈配合将抽气孔3堵住,当电池短路或碰撞时,壳体1内部产生大量气体,壳体1内部气压增大会将塞子4往外压,当塞子4往外压时气孔42就会与壳体1外部相通,壳体1内的气体就会通过气道411流出到壳体1外部从而壳体1内部的气压降低,当气压降低后塞子4又回复到起初的位置将抽气孔3堵住,这样就有效防止了电池爆炸。
