具体实施方式
为使本申请实施方式的目的、技术方案和优点更加清楚，下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述，显然，所描述的实施方式是本申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施方式，都属于本申请保护的范围。因此，以下对在附图中提供的本申请的实施方式的详细描述并非旨在限制要求保护的本申请的范围，而是仅仅表示本申请的选定实施方式。
在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
在本申请的第一方面，提供一种防护组件10，参见图1至图12所示，防护组件10包括：防护件110和防护盖130，防护件110包括：防护件本体111和高压绝缘座112，防护件本体111沿第一方向延伸，防护件本体111沿与第一方向相交的第二方向具有彼此相背的第一侧面1111和第二侧面1112，高压绝缘座112的数量为两个，且两个高压绝缘座112分别设置在防护件本体111第一侧面1111的两端，一个高压绝缘座112用于固定正极母排，一个高压绝缘座112用于固定负极母排102，防护盖130的数量为两个，两个防护盖130分别盖合于两个高压绝缘座112上；其中，防护件本体111的第一侧面1111设置有与电池模组100的盖板103连接的第一连接部113，第二侧面1112设置有与电池模组100的端板104连接的第二连接部114。
具体来讲，上述中的防护件本体111可以是平板状，也可以是如图1中所示出的有两个台阶，两个台阶中间开设有减重缺口，且两个高压绝缘座112分别设置于一个台阶上；上述中的防护件本体111沿与第一方向相交的第二方向具有彼此相背的第一侧面1111和第二侧面1112，此处的相交是指第一方向和第二方向不平行，比如：第二 方向与第一方向垂直。
上述中的一个高压绝缘座112用于固定正极母排，一个高压绝缘座112用于固定负极母排102，这里的固定可以是夹设式的固定，也可以是螺接式的固定，还可以是其他方式的固定，此处不做具体限定。
上述中的两个防护盖130分别盖合于两个高压绝缘座112上，换言之，一个防护盖130盖合于一个高压绝缘座112上，另一个防护盖130盖合于另一个高压绝缘座112上。
在一个具体实施例中，参见图9至图12所示，装配电池模组100时，首先，通过防护组件10第二表面1112侧的第二连接部114将防护组件10固定于电池模组100的端板104的上端；而后，将正极母排和负极母排102分别固定于两个高压绝缘座112上，并将两个防护盖130分别盖合于两个高压绝缘座112上；最后，通过防护组件10第一表面1111侧的第一连接部113与电池模组100的盖板103连接即可。
在本申请实施例中，通过一个防护组件能够同时固定正极母排和负极母排，从而能够减少电池模组的零部件数量，提高电池模组的集成度。
具体实施时，防护盖130可以是可拆卸的盖合于高压绝缘座上112，这里的可拆卸的盖合可以是防护盖130卡合式的盖合于高压绝缘座112上，也可以是防护盖130螺接式的盖合于高压绝缘座112上，还可以是其他方式的可拆卸式盖合连接方式。
在本申请一个实施例中，参见图1、图2、图4至图6及图9所示，高压绝缘座112沿第二方向开设有具有内螺纹的孔位1121，且高压绝缘座112沿第一方向的两个彼此相背的侧面分别设置有第一卡合部1122，防护盖130的内侧设置有适配第一卡合部1122的第二卡合部1301；其中，第二方向与第一方向垂直。
具体来讲，上述中的高压绝缘座112沿第二方向开设有具有内螺纹的孔位1121，由此通过一个具有外螺纹的螺柱穿过正极母排和一个高压绝缘座112上的孔位1121能够将正极母排固定于防护组件10的一个高压绝缘座112上，进而通过另一个具有外螺纹的螺柱穿过负极母排102和另一个绝缘座112上的孔位1121能够将负极母排102固定于防护组件10的另一个高压绝缘座112上；上述中的高压绝缘座112沿第一方向的两个彼此相背的侧面分别设置有第一卡合部1122，防护盖130的内侧设置有适配第一卡合部1122的第二卡合部1301，这里，第一卡合部1122和第二卡合部1301中，一个可以是凸起，另一个是与凸起适配的凹部，比如：第一卡合部1122为条形凸起，条形凸起的延伸方向为与第一方向垂直的第三方向，第二卡合部1301为条形凹槽；或者，第一卡合部1122为如图1-图12中所示出的条形凹槽，条形凹槽的延伸方向为与第一方向垂直的第三方向，第二卡合部1301为如图1-图12中所示出的条形凸起。
当第一卡合部1122为条形凸起，条形凸起的延伸方向为与第一方向垂直的第三方向，第二卡合部1301为条形凹槽时，第一卡合部1122的上端为斜面，换言之，第一卡合部1122沿第一方向的截面为梯形或三角形，从而使得防护盖130盖合于高压绝缘座112时沿着斜面缓缓卡入，以防止高压绝缘座112上的第一卡合部1122断裂；同样 地，当第一卡合部1122为如图1-图12中所示出的条形凹槽，条形凹槽的延伸方向为与第一方向垂直的第三方向，第二卡合部1301为如图1-图12中所示出的条形凸起时，参见图8所示，第二卡合部1301的下端为斜面，换言之，第二卡合部1301沿第一方向的截面为梯形或三角形，从而使得防护盖130盖合于高压绝缘座112时沿着斜面缓缓卡入，以防止防护盖130上的第二卡合部1301断裂。
需要说明的是，为了使防护盖130卡合于高压绝缘座112时更顺利，参见图8所示，防护盖130沿第一方向的两个侧部分别开设有孔1302，以提升防护盖130沿第一方向的两个侧部的弹性，以使防护盖130在卡入高压绝缘座112时微变形，从而使得防护盖能够更顺利的卡合于高压绝缘座。
在本申请一个具体实施例中，参见图1至图12所示，高压绝缘座112沿第二方向设置有嵌螺母以形成具有内螺纹的孔位1121，而嵌螺母与高压绝缘座112之间的连接结构更牢固，从而使得防护组件的结构强度更好。
在本申请一个实施例中，参见图5和图6所示，高压绝缘座112背离防护件本体111第一侧面1111的表面设置有母排限位结构1123，母排限位结构1123包括：第一条形限位凸起和第二条形限位凸起，第一条形限位凸起和第二条形限位凸起均垂直于第一方向；其中，第一条形限位凸起和第二条形限位凸起之间的间隔距离等于母排的宽度，由此，正极母排/负极母排102置于第一条形限位凸起和第二条形限位凸起之间时受到第一条形限位凸起和第二条形限位凸起限制，以防止正极母排/负极母排在装配时的移位，从而能够提升装配效率。
在本申请一个实施例中，参见图4和图5所示，防护组件10还可以包括：限位结构115，限位结构115设置在防护件本体111的第二侧面1112，限位结构115包括：长度不同的第一限位柱和第二限位柱，第一限位柱的一端和第二限位柱的一端均与防护件本体111的第二侧面1112连接，第一限位柱和第二限位柱紧挨且第一限位柱和第二限位柱的连线与第一方向垂直。本实施例中，当通过具有外螺纹的螺柱将正极母排/负极母排螺接于高压绝缘座112上的孔位1121时，需要旋动螺柱，该过程将导致防护件本体的转动，而限位结构能够限制旋动螺柱时防护件本体的转动，从而提升装配效率。
在本申请一个实施例中，参见图1、图2及图4-图6所示，第二连接部114为自防护件本体111的第二侧面1112向远离防护件本体111第二侧面1112的方向延伸的卡接脚，卡接脚远离防护件本体111第二侧面1112的一端设置有勾合部；其中，限位结构115的数量为多个，至少一个第二连接部114设置在两个限位结构115之间。本实施例中通过具有勾合部的卡接脚来实现防护组件与电池模组的端板的连接，不仅结构简单，而且制作简便。
具体实施时，其一，卡合部的延伸方向可以是沿着第一方向，可以是与第一方向相反的第二方向，还可以是与第一方向垂直且不是第二方向的方向，当卡接脚的数量为多个时，多个卡接脚上的卡合部的延伸方向可以彼此相同，也可以彼此不同，当彼 此不同时使得防护组件和电池模组的端板连接更牢固，故优选多个卡接脚上的卡合部的延伸方向彼此不同；其二，第二连接部114的数量可以是多个，而限位结构115的数量也可以是多个，彼此交错设置，以更好的防止防护件本体的转动。
在本申请一个实施例中，参见图5和图7所示，第一连接部113为自防护件本体111的第一侧面1111向远离防护件本体111第一侧面1111的方向延伸的第一凸部，第一凸部沿第二方向开设有螺接孔位1131，且第一连接部113设于两个高压绝缘座112之间，第一凸部为具有开口的空心结构；和/或，参见图1所示，防护件本体111的第一侧面1111向远离防护件本体111第一侧面的方向延伸有第二凸部116，第二凸部116背离防护件本体111的表面向远离第二凸部116的方向延伸有定位柱1161。
具体来讲，上述中的第一连接部113为自防护件本体111的第一侧面1111向远离防护件本体111第一侧面1111的方向延伸的第一凸部，第一凸部沿第二方向开设有螺接孔位1131，这里，电池模组100的盖板103开设有与螺接孔位1131适配的孔位，从而能够通过螺柱将盖板103和第一凸部连接；上述中的防护件本体111的第一侧面1111向远离防护件本体111第一侧面的方向延伸有第二凸部116，第二凸部116背离防护件本体111的表面向远离第二凸部116的方向延伸有定位柱1161，这里，电池模组100的盖板103开设有与定位柱1161对应的定位孔，从而在将第一凸部和盖板103连接时能够通过定位柱和定位孔的配合更快速的将第一凸部的螺接孔位1131对准盖板103上与此对应的孔位。
本实施例中，其一，通过螺接孔位使得能够通过螺柱螺接电池模组的盖板和防护组件的方式实现电池模组的盖板和防护组件的连接，且空心结构能够减少防护组件的制作材料，减轻防护组件的重量，同时降低防护组件的制作成本；其二，通过定位柱能够在防护组件与盖板连接的过程中预先定位，从而能够提升防护组件与盖板之间的安装效率。
具体实施时，防护组件10可以开设孔位、缺口等以减少防护组件的制作材料，减轻防护组件的重量，同时降低防护组件的制作成本。
基于同一发明构思，本申请第二方面提供一种电池模组100，参见图9至图12所示，电池模组100包括：防护组件10和框体，框体设置有容置电芯的容置空间，框体包括：第一端板、第一侧板、第二端板、第二侧板及底板，第一端板、第一侧板、第二端板及第二侧板依次首尾连接并均连接在底板的同一侧以限定出容置空间；其中，第一端板远离底板的表面设置有连接防护组件10的第二连接部114的第三连接部105。
本实施例中，通过将第一方面中的防护组件设置在电池模组中，从而能够减少电池模组的零部件数量、提高电池模组的集成度。
在本申请一个具体实施例中，参见图9至图12所示，第三连接部105为第一端板远离底板的表面凹陷所形成的凹槽，凹槽的形状与防护组件10的第二连接部114和限位结构115相匹配，换言之，第二连接部114和限位结构115均插接于凹槽内，且凹 槽内开设有适配勾合部的勾合凹部，勾合部和勾合凹部的配合以使防护组件固定于第二端板上。本实施例中凹槽的设置结构简单，且便于制作。
需要说明的是，本申请实施例提供的电池模组中的防护组件与第一方面中的防护组件实施例的描述是类似的，具有同第一方面中防护组件实施例相似的有益效果。对于本申请电池模组实施例中未披露的技术细节，请参照本申请中防护组件实施例的描述而理解，此处不再赘述。
在本申请的描述中，需要理解的是，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。
另外，在本申请的描述中，需要理解的是，术语“纵”、“横”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“轴向”、“径向”、“”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申请和简化描述，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申请的限制。
此外，在本申请中，除非另有明确的规定和限定，术语“连接”、“相连”等应做广义理解，例如可以是机械连接，也可以是电连接；可以是直接连接，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定、对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
