在本申请中，所提及的电池是指包括多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提及的电池可以包括电池模块或电池包等。
电池包括围框和设置于围框内的电池单体。围框通常包括侧板和端板，侧板与端板连接围成空间，以容纳电池单体，实现对电池单体的定位。围框的材质通常为金属，具有较好的强度，便于保护电池单体。
电池的生产过程中，电池的生产效率是一个不可忽视的问题。对于电池制造来说，影响生产效率的主要因素是装配质量，例如，围框的装配质量。
发明人发现，现有技术中，为了保证围框具有一定的强度，侧板与端板的连接通常采用焊接的方式固定。侧板与端板焊接前，需要在侧板与端板的连接处预留焊接所需缝隙，以便于侧板与端板焊接。侧板与端板焊接时，容易出现爆孔、虚焊、下塌等不良问题，进而影响焊缝强度，导致围框的强度不足。引起上述不良问题的原因在于：侧板与端板焊接定位夹具装配不到位，导致焊缝错位，装配间隙过大容易下塌或虚焊，焊接功率过大或焊接表面脏污容易导致爆孔，影响围框的装配质量，从而影响装配良品率，导致生产效率较低。
鉴于此，为了解决围框的装配质量较低而导致生产效率较低的问题，发明人经过深入研究，设计了一种围框，该围框包括一对侧板和一对端板，一对侧板沿第一方向相对设置，一对端板沿与第一方向垂直的第二方向相对设置，端板设置于一对侧板之间，端板与侧板采用第一凸起与第一凹槽嵌入压合的方式连接，保证连接强度。
该围框，通过第一凸起与第一凹槽的嵌入压合的方式，实现端板与侧板的连接，替代了焊接的连接方式，避免了焊接不良导致的围框强度较弱的情况，能够保证端板与侧板的连接强度，使得整个围框具有较高的强度，装配质量高，生产效率高。

请参照图4至图7，图4为本申请一些实施例提供的围框11的结构示意图，图5为图4的A处局部放大图，图6为本申请一些实施例提供的围框11的结构示意图，图7为图6的B处放大图。
根据本申请的一些实施例，本申请提供了一种围框11，用于电池100，如图4至图7所示，围框11包括一对侧板111和一对端板112。一对侧板111沿第一方向X相对设置，一对端板112沿与第一方向X垂直的第二方向Y相对设置，端板112设置于一对侧板111之间。其中，端板112的沿第一方向X的两端分别设置有第一凹槽121，侧板111的面向端板112的一侧设置有第一凸起122；或者，端板112的沿第一方向X的两端分别设置有第一凸起122，侧板111的面向端板112的一侧设置有第一凹槽121；第一凸起122被配置为嵌入第一凹槽121，以限制端板112相对于侧板111沿第二方向Y移动。
如图2所述，电池100包括围框11和多个电池单体20，多个电池单体20堆叠设置于围框11内。一对端板112分别位于电池单体20堆叠方向的两端，也即，第二方向Y为电池单体20的堆叠方向，端板112用于在电池单体20的堆叠方向上对电池单体20起到限位的作用。
一对侧板111沿第一方向X相对设置，端板112设置于一对侧板111之间，侧板111和端板112围成用于容纳电池单体20的空间。端板112的沿第一方向X的两端分别与侧板111连接，限制端板112相对于侧板111沿第二方向Y移动，即可实现对电池单体20在第二方向Y上的限位。
本申请实施例的端板112和侧板111均为金属件，具有较好的强度，同时，侧板111具有一定的韧性，侧板111能够发生形变，且发生形变后，侧板111仍具有较好的强度。端板112与电池单体20的大面相对应，端板112与电池单体20具有较大的对应面积，端板112用于在第二方向Y上对电池单体20起到限位以及保护电池单体20的作用，因此，端板112的厚度较厚，端板112的厚度通常大于侧板111的厚度。
如图4和图5所示，在端板112的沿第一方向X的两端分别设置有第一凹槽121，侧板111的面向端板112的一侧设置有第一凸起122的方案中，端板112的沿第 一方向X的两端的结构相同，便于加工；由于侧板111的厚度相对端板112的厚度小，侧板111相对于端板112容易发生形变，在侧板111与端板112配合时，侧板111朝向端板112挤压并嵌入端板112的第一凹槽121内，当侧板111与端板112配合后，侧板111的嵌入第一凹槽121的部分形成第一凸起122。
如图6和图7所示，在端板112的沿第一方向X的两端分别设置有第一凸起122，侧板111的面向端板112的一侧设置有第一凹槽121的方案中，端板112的沿第一方向X的两端的结构相同，便于加工；由于侧板111的厚度相对于端板112的厚度小，侧板111相对于端板112容易发生形变，在侧板111与端板112配合时，侧板111朝向端板112挤压并包裹端板112的第一凸起122，当侧板111与端板112配合后，侧板111的包裹第一凸起122的部分形成第一凹槽121。
根据本申请实施例的围框11，用于电池100，以容纳电池单体20，通过第一凸起122与第一凹槽121的嵌入压合的连接方式，实现端板112与侧板111的连接，替代了焊接的连接方式，避免了焊接不良导致的围框11强度较弱的情况，能够保证端板112与侧板111的连接强度，使得整个围框11具有较高的强度，装配质量高，生产效率高。
根据本申请的一些实施例，可选地，如图4至图7所示，第一凸起122和第一凹槽121均沿第三方向Z延伸，第三方向Z垂直于第一方向X和第二方向Y。
第一凸起122和第一凹槽121均沿第三方向Z延伸，第三方向Z可以为第一凸起122的长度方向，也即，第三方向Z可以为第一凹槽121的长度方向，使得第一凸起122和第一凹槽121在第三方向Z上具有较长的尺寸，端板112与侧板111在第三方向Z上具有较长的连接区域，换句话说，端板112和侧板111在第三方向Z上具有较高的连接稳定性。
可选地，在端板112的沿第一方向X的两端分别设置有第一凹槽121、侧板111的面向端板112的一侧设置有第一凸起122的方案中，第一凹槽121可以沿第三方向Z贯穿端板112，也即，第一凹槽121可以由端板112的第三方向Z上的一端延伸至端板112的第三方向Z上的另一端，使得端板112与侧板111的连接稳定性较强，同时，便于加工成型，降低制造成本。
可选地，在端板112的沿第一方向X的两端分别设置有第一凸起122、侧板111的面向端板112的一侧设置有第一凹槽121的方案中，第一凸起122可以沿第三方 向Z贯穿端板112，也即，第一凸起122可以由端板112的第三方向Z上的一端延伸至端板112的第三方向Z上的另一端，使得端板112与侧板111的连接稳定性较强，同时，便于加工成型，降低制造成本。
第一凸起122和第一凹槽121沿第三方向Z延伸，保证端板112与侧板111的连接稳定性，以便于限制端板112相对于侧板111沿第二方向Y移动。
根据本申请的一些实施例，可选地，沿第一凹槽121的底部指向第一凹槽121的开口的方向，第一凹槽121的宽度逐渐增大。
例如，图8为本申请一些实施例提供的端板112的俯视图，图9为图8的C处局部放大图，如图8和图9所示，以端板112的沿第一方向X的两端分别设置有第一凹槽121为例，第一方向X为第一凹槽121的深度方向，第一凹槽121沿第一方向X开设，也即，第一凹槽121的开口和第一凹槽121的底部沿第一方向X分布。
沿第一凹槽121的底部指向第一凹槽121的开口的方向，第一凹槽121的宽度逐渐增大，换句话说，第一凹槽121的开口较大，随着第一凹槽121的深度的增加，第一凹槽121宽度逐渐减小，便于加工成型；同时，第一凹槽121的设置形式，便于第一凸起122嵌入第一凹槽121，便于实现侧板111与端板112的压合，保证侧板111与端板112接触良好，保证端板112与侧板111的连接稳定性。
根据本申请的一些实施例，可选地，第一凸起122与第一凹槽121之间填充有密封胶。
第一凸起122与第一凹槽121之间填充有密封胶，可以为在端板112与侧板111配合之前，在第一凸起122或第一凹槽121内涂敷密封胶，再将第一凸起122嵌入第一凹槽121内，实现端板112与侧板111的连接，保证第一凸起122与第一凹槽121之间的密封胶分布均匀。
第一凸起122与第一凹槽121嵌入压合后，第一凸起122与第一凹槽121的槽面贴合，密封胶填充于第一凸起122与第一凹槽121之间，实现端板112与侧板111之间的连接密封，避免液体或其他杂质等进入围框11内，保证围框11的密封效果。
根据本申请的一些实施例，可选地，第一凹槽121的底部设置有溢胶槽123。
溢胶槽123为用于容纳密封胶的区域，在端板112与侧板111装配前，在溢胶槽123内涂敷密封胶，在第一凸起122嵌入第一凹槽121内时，第一凸起122的凸出部嵌入溢胶槽123并将溢胶槽123内的密封胶挤出以填满第一凹槽121，实现强度密 封。
如图4、图5和图9所示，端板112的沿第一方向X的两端分别设置有第一凹槽121，溢胶槽123位于第一凹槽121的底部。
溢胶槽123位于第一凹槽121的底部，以便于在第一凸起122与第一凹槽121嵌合时，引导密封胶流动，使得密封胶能够填满第一凹槽121，保证第一凸起122与第一凹槽121密封配合。
根据本申请的一些实施例，可选地，溢胶槽123的截面为矩形。
溢胶槽123设置于第一凹槽121的槽底，并且溢胶槽123的延伸方向与第一凹槽121的延伸方向一致。溢胶槽123沿垂直于第一凹槽121的底部的方向开设，例如，溢胶槽123可以沿第一方向X开设。
溢胶槽123的截面是指在垂直于溢胶槽123的延伸方向的平面上的截面。
矩形的溢胶槽123，便于加工，同时有利于侧板111与端板112在自动冲压时提前寻址端板112冲压位置，便于实现侧板111与端板112的冲压定位。
在其他实施例中，溢胶槽123的截面还可以为其他形状，例如三角形、多棱形或异形等。
根据本申请的一些实施例，可选地，第一凸起122的与第一凹槽121的底部对应的凸出部设置有溢胶槽123。
如图6和图7所示，端板112的沿第一方向X的两端分别设置有第一凸起122，溢胶槽123位于第一凸起122的与第一凹槽121的底部对应的位置。
根据本申请的一些实施例，可选地，沿第二方向Y，侧板111的两端分别超出一对端板112。
侧板111的两端分别超出一对端板112是指，沿第二方向Y，端板112的外表面到与其相邻的侧板111的端部之间具有一定的距离。端板112的外表面是指端板112的远离另一个端板112的表面。
侧板111的端部超出端板112，预留侧板111折弯长度，以保证侧板111与端板112压合时，侧板111与端板112具有较大的连接面积，保证侧板111与端板112的连接稳定性。
根据本申请的一些实施例，可选地，沿第二方向Y，侧板111超出端板112的长度为10mm-20mm。
侧板111超出端板112的长度是指，沿第二方向Y，侧板111的端部和与其相邻的端板112之间的距离。
侧板111超出端板112的长度满足10mm-20mm，保证侧板111与端板112的连接稳定性，保证围框11围成的空间较大。如果侧板111超出的长度过大，则浪费安装空间。
请参照图10，图10为本申请一些实施例提供的围框11的分解结构示意图。根据本申请的一些实施例，可选地，如图10所示，围框11还包括：底板113，一对侧板111从底板113的沿第一方向X的两个边缘沿垂直于底板113的方向延伸，如图4和图6所示，一对端板112位于底板113和一对侧板111围成的空间内。
一对侧板111从底板113的沿第一方向X的两个边缘沿垂直于底板113的方向延伸，可以理解为，一对侧板111与底板113构成U字形结构。
一对端板112位于底板113和一对侧板111围成的空间内，沿第三方向Z，端板112位于底板113上。

隔板114为用于分隔围框11内的空间的部件，以将围框11内的空间分区。隔板114的数量可以为一个或多个，根据设计需求设置隔板114的数量。
当围框11设置有隔板114时，隔板114与侧板111连接，便于分割围框11围成的空间，便于管理设置于围框11内的电池单体20。
根据本申请的一些实施例，隔板114的沿第一方向X的两端分别设置有第二凹槽，侧板111的面向隔板114的一侧设置有第二凸起，或者，隔板114的沿第一方向X的两端分别设置有第二凸起，侧板111的面向隔板114的一侧设置有第二凹槽； 第二凸起被配置为嵌入第二凹槽，以限制隔板114相对于侧板111沿第二方向Y移动。

在隔板114的沿第一方向X的两端分别设置有第二凹槽，侧板111的面向隔板114的一侧设置有第二凸起的方案中，隔板114的沿第一方向X的两端的结构相同，便于加工；由于侧板111的厚度相对隔板114的厚度小，侧板111相对于隔板114容易发生形变，在侧板111与隔板114配合时，侧板111朝向隔板114挤压并嵌入隔板114的第二凹槽内，当侧板111与隔板114配合后，侧板111的嵌入第二凹槽的部分形成第二凸起。
在隔板114的沿第一方向X的两端分别设置有第二凸起，侧板111的面向隔板114的一侧设置有第二凹槽的方案中，隔板114的沿第一方向X的两端的结构相同，便于加工；由于侧板111的厚度相对于隔板114的厚度小，侧板111相对于隔板114容易发生形变，在侧板111与隔板114配合时，侧板111朝向隔板114挤压并包裹隔板114的第二凸起，当侧板111与隔板114配合后，侧板111的包裹第二凸起的部分形成第二凹槽。
隔板114与侧板111采用第二凸起与第二凹槽嵌入压合的方式，保证隔板114与侧板111的连接强度。当需要设置隔板114时，需要先将隔板114与一对侧板111装配，再进行端板112与一对侧板111的装配。
