具体实施方式
在本发明的描述中,需要理解的是,术语“上”、“下”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。
下面通过实施例的方式并结合附图来更清楚完整地说明本发明的第一方面,但并不因此将本发明限制在的实施例范围之中。
如图1-4所示,本实施例1的电池包组件包括电池包总成10和电池固定座20,电池包总成10可拆卸地连接于电池固定座20。该电池包总成10包括电池包1和液冷插件2,电池包1用于安装在电池固定座20内,电池包1可拆卸地连接于电池固定座20内,且电池包1能够在电池固定座20内沿电池包1的长度方向移动,液冷插件2安装于电池包1,且液冷插件2用于插入外部的散热系统30并与散热系统30相连通,液冷插件2的插入方向与电池包1的移动方向相同。
电池包1在电池固定座20内沿电池包1的长度方向移动时,液冷插件2的插入方向与电池包1的移动方向相同,使得液冷插件2能够沿靠近或者远离散热系统30的方向移动,并与外部的散热系统30之间实现插入或者断开,散热系统30可以安装固定在电池固定座20上。当液冷插件2与散热系统30相连通时,外部的散热系统30提供的冷却水将会通过液冷插件2进入至电池包1内,能够均衡电池包1温度,提高电池包1充分能力,直接提高电池包1的使用寿命。同时,便于插接,满足频繁更换。
液冷插件2可以包括设置于电池包1内的至少一个散热管21,散热管21的两端部均露出于电池包1的外表面并用于与散热系统30相连通。散热管21分布于电池包1内能够有效对电池包1内产生的热量进行散热,从而更好地均衡电池包1温度,提高电池包1的性能和使用寿命。同时,散热管21的两端部均露出于电池包1的外表面,便于散热管21的两端与散热系统30相连通。其中,散热管21的一端的插接端口用于输送散热系统30提供的冷却水,散热管21的另一端的插接端口用于排出散热 系统30提供的冷却水,使得外部的散热系统30提供的冷却水通过散热管21能够实现对电池包1的循环冷却,有效对电池包1进行散热,提高电池包1的性能和使用寿命。其中,液冷插件2包括有安装板22,安装板22位于电池包1的外表面并与散热管21相连接。
电池包1的侧壁上设有至少一个第一导向部23,第一导向部23可以沿液冷插件2的插入方向延伸凸起。电池包总成10与散热系统30在插接的过程中,电池包1沿液冷插件2的插入方向移动,使得第一导向部23插入至电池固定座20内,第一导向部23起到导向定位作用,提高了电池包总成10与散热系统30之间的插接精度,大大增强了液冷插件2连接的稳定性,有效避免了渗漏现象。其中,第一导向部23可以连接在安装板22上。当然,在本实施方式中,第一导向部23也可以沿液冷插件2的插入方向向内凹陷。
电池包总成10还可以包括电连接器3,电连接器3包括有极柱安装座31和导电极柱32,极柱安装座31连接于电池包1,极柱安装座31设有安装孔,导电极柱32穿设安装孔,导电极柱32的外壁面上具有至少一个限位部321,限位部321用于限制导电极柱32相对于极柱安装座31沿安装孔的轴线方向向内移动。限位部321抵靠于极柱安装座31并限制导电极柱32在安装孔内的轴线方向向内移动,提高了导电极柱32与极柱安装座31的连接可靠性,进而提高了电连接器3连接的可靠性。
限位部321可以沿安装孔的径向方向向外凸起,且限位部321抵靠于安装孔的内壁面。限位部321凸起的结构不作限定,限位部321的结构可以呈环状、倒刺状等,结构简单,加工制作方便。
安装孔的轴线方向与液冷插件2的插入方向相同。液冷插件2在插接过程中,通过限位部321能够在插接过程中有效限定了导电极柱32在极柱安装座31内的移动,有效避免了导电极柱32在插接过程中产生偏移错位现象,提高了电连接器3在插接过程中电连接的可靠性。
极柱安装座31背向电池包1的一侧设有第二导向部33,第二导向部33可以沿液冷插件2的插入方向延伸凸起。电连接器3通过第二导向部33插入至电池固定座20内并与电池固定座20上的连接器实现电连接,第二导向部33起到导向定位的作用,提高了电连接器3的连接精度,提高了电连接器3电连接的稳定可靠性。当然,第二导向部33也可以沿液冷插件2的插入方向向内凹陷。
电池包总成10还可以包括多个导向限位件4,多个导向限位件4分别连接于电池包1中位于电池包1的长度方向上的两侧壁,且导向限位件4设置成抵靠于电池固定座20中位于电池固定座20的长度方向上两侧壁的内壁面,以将电池包1夹紧于电池固定座20内,电池固定座20的长度方向与电池包1的长度方向相同。导向限位件4在电池包总成10的安装过程中起到导向作用,在电池包总成10安装完成后,电池包总成10的两侧通过多个导向限位件4抵靠于电池固定座20内,使得电池包总成10的两侧在宽度方向上对电池固定座20具有一定的作用力,有效减小电池包1与电池固定座20之间的磨损,提高了电池包1的使用寿命。
