具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下文的公开提供了许多不同的实施例或例子用来实现本申请的不同结构。为了简化本 申请的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本申请。此外，本申请可以在不同例子中重复参考数字和/或字母。这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施例和/或设置之间的关系。此外，本申请提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的可应用于性和/或其他材料的使用。
下面参考附图描述根据本申请实施例的集流盘100、储能装置200及用电设备300。
如图1、图2和图3所示，根据本申请第一方面的实施例的集流盘100，包括集流本体1、第一翻边2和第二翻边3，集流本体1沿轴向相对的两侧为第一表面和第二表面，第一翻边2连接集流本体1的外边沿，第一翻边2相对集流本体1朝向第一表面弯折，第二翻边3连接第一翻边2的外边沿，第二翻边3相对第一翻边2朝向所述第二表面弯折，且沿远离集流本体1的中心方向延伸设置壳体101。
需要说明是的，集流本体1的第一表面为靠近卷芯102的一侧，第二表面为远离卷芯102的一侧。第二翻边3沿远离集流本体1的中心方向延伸设置，可以理解为第二翻边3沿远离电池的卷芯102的方向延伸设置。
具体的，如图1、图2和图3所示，本申请实施例的集流盘100包括集流本体1，集流本体1沿轴向相对的两侧为第一表面和第二表面，请结合图7，第一表面用于与电池的卷芯102连接，第二表面用于与电池的端盖104连接。第一翻边2连接集流本体1的外边沿，第一翻边2相对集流本体1朝向内侧弯折以扣在电池的卷芯102上，从而将集流本体1定位在卷芯102上，使得集流本体1与卷芯102进行焊接时，不易发生偏移，方便进行焊接操作。第二翻边3连接第一翻边2的外边沿，第二翻边3相对第一翻边2朝向第二表面弯折，且沿远离集流本体1的中心方向延伸设置以抵接电池的壳体101，第二翻边3抵接在电池的壳体101上，对集流盘100和卷芯102的相对位置进一步定位，提高了定位效果，同时，第二翻边3连接在第一翻边2的外边沿，第二翻边3相对第一翻边2朝向第二表面弯折，且远离集流本体1的中心方向设置，这样，第一翻边2和第二翻边3能够形成夹角，当第一翻边2一侧受到卷芯102挤压时，抵接在电池的壳体101的第二翻边3在另一侧提供一定的支撑力，使得第一翻边2不易变形，保证了第一翻边2对集流盘100和卷芯102的定位效果，便于集流盘100与卷芯102的装配。
由此，根据本申请的集流盘100，通过在第一翻边2的外边沿连接第二翻边3，第二翻边3相对第一翻边2朝向所述第二表面弯折，且沿远离集流本体1的中心方向延伸设置以抵接电池的壳体101，第二翻边3抵接在电池的壳体101上，对集流盘100和卷芯102的相对位置进一步定位，提高了定位效果，同时，第二翻边3使得第一翻边2受到挤压时不易变形，保证了第一翻边2对集流盘100和卷芯102的定位效果，便于集流盘100与卷芯 102的装配。
可以理解的是，第一翻边2的延伸方向与集流本体1的延伸方向之间的夹角可以为锐角、直角或钝角。例如，如图4所示，当第一翻边2与集流本体1的夹角为锐角时，集流本体1的尺寸大小大于卷芯102横截面的尺寸大小；如图5所示，当第一翻边2与集流本体1的夹角为直角时，集流本体1的尺寸大小可以等于卷芯102横截面的尺寸大小；如图6所示，当第一翻边2与集流本体1的夹角为钝角时，集流本体1的尺寸大小等于卷芯102横截面的尺寸大小。其中，此处的“尺寸”可以是面积、直径、长度或宽度中的任意一个。具体地，当“集流本体1的尺寸”是指集流本体1的面积，则“卷芯102横截面的尺寸”是指卷芯102横截面的面积；当“集流本体1的尺寸”是指集流本体1的直径，则“卷芯102横截面的尺寸”是指卷芯102横截面的直径，集流本体1和卷芯102横截面二者均为圆形；当“集流本体1的尺寸”是指集流本体1的长度，则“卷芯102横截面的尺寸”是指卷芯102横截面的长度，集流本体1和卷芯102横截面二者均为矩形；当“集流本体1的尺寸”是指集流本体1的宽度，则“卷芯102横截面的尺寸”是指卷芯102横截面的宽度，集流本体1和卷芯102横截面二者均为矩形。
在本申请的一些实施例中，如图3所示，第一翻边2的延伸方向与集流本体1的延伸方向之间的夹角为第一夹角，第一夹角大于90度，使得集流本体1的尺寸大小可以设置为与电池的卷芯102(图7所示)的横截面的尺寸大小相同，节省了生产成本，且便于将集流盘100盖扣在电池的电芯上。此处的“尺寸”的解释同上文，在此不再赘述。
在一些实施例中，电池的卷芯102在靠近上述集流盘100的一端为上表面，上表面与卷芯102的侧面的夹角为第三夹角，第三夹角与第一夹角的角度相同，以便于集流盘100与电池的卷芯102贴合。
在本申请的一些实施例中，如图1所示，第一翻边2与第二翻边3之间的夹角为第二夹角，第二夹角小于90度，增大了第二翻边3与电池的壳体101(图7所示)之间的抵接面的面积，提高了第二翻边3与电池的壳体101连接的稳定性。
在一些实施例中，第二翻边3与电池的壳体101之间具有重合面。优选的，第二翻边3完全贴合在电池的壳体101上。
在本申请的一些实施例中，如图1所示，沿所述集流本体1的轴向，第二翻边3的边沿超过第一表面，进一步增大了第二翻边3与电池的壳体101之间的抵接面的面积，这样，提高了第一翻边2和第二翻边3在集流本体1与电池的壳体101之间形成的弯折的弹性件的结构稳定性，延长了弹性件的使用寿命。
在一些实施例中，如图1和图2所示，第一翻边2与集流本体1之间的第一连接线为圆形或圆弧形，第一翻边2为沿第一连接线延伸的曲面片，使得第一翻边2沿电池的卷芯 102和集流本体1的周向设置，便于扣在电池的卷芯102上。
需要说明的是，电池的卷芯102为圆柱状，集流本体1的外轮廓为圆形。当第一翻边2与集流本体1之间的第一连接线为圆形时，第一翻边2为绕集流本体1外轮廓的圆环状的曲面片；当第一翻边2与集流本体1之间的第一连接线为圆弧形时，第一翻边2为圆弧状的曲面片，且第一翻边2为多个，多个第一翻边2沿集流本体1的外轮廓均匀分布，例如，第一翻边2可以为三个、四个、五个、六个等。
在一些实施例中，如图1和图2所示，第一翻边2与所述第二翻边3之间的第二连接线为圆形或圆弧形，第二翻边3为沿第二连接线延伸的曲面片，使得第二翻边3与第一翻边2连接的一侧与第一翻边2的外边沿完全重合，对第一翻边2的各处进行缓冲，进一步减小了第一翻边2受到挤压时发生变形的几率。
在一些实施例中，第一翻边2与集流本体1之间为圆弧过渡连接；第一翻边2与第二翻边3之间为圆弧过渡连接，便于第一翻边2与集流本体1的连接以及第一翻边2与第二翻边3的连接，同时，提高了第一翻边2与集流本体1以及第一翻边2与第二翻边3之间的弹性缓冲作用，减小了第一翻边2受到挤压发生变形的几率，且节省了材料。
在本申请的一些实施例中，如图1和图2所示，集流本体1包括主体部11、第一连接部12和第二连接部13，第一连接部12连接主体部11，第一连接部12为至少两个且环绕主体部11分布，第一翻边2连接在第一连接部12的远离主体部11的一端，第二连接部13位于相邻两个第一连接部12之间，且在周向方向上每相邻两个第一连接部12均设置有第二连接部13，第二连接部13用于连接卷芯102，第二连接部13连接主体部11和第一翻边2中至少一个。主体部11通过第一连接部12连接第一翻边2，第一翻边2环绕集流本体1分布，对集流本体1的各个方向进行定位，通过第二连接部13连接卷芯102，第二连接部13位于相邻两个第一连接部12之间，且在周向方向上每相邻两个第一连接部12均设置有第二连接部13，使得卷芯102与集流本体1具有多个连接位点，提高了连接的可靠性和稳定性。
在一些实施例中，如图1和图2所示，每个第二连接部13上设有多条焊线131，焊线131在沿第二连接部13的厚度方向上贯通，便于将第二连接部13与电池的卷芯102进行焊接。在本申请中，第二连接部13为花瓣状。
在一些实施例中，第二连接部13与主体部11或第一翻边2连接。
在本申请的一些实施例中，如图1和图2所示，第一连接部12和第二连接部13之间形成有第一隔槽14，第一隔槽14在集流盘100的厚度方向上贯通设置，使得第一连接部12和第二连接部13的至少部分可分离，当卷芯102震动时，第二连接部13可相对主体部11弯曲一定角度，以缓冲部分力的作用，从而降低第二连接部13与卷芯102的连接断开 的几率。
在本申请的一些实施例中，第一翻边2为环形且连接所有第一连接部12，环形第一翻边2便于生产安装，提高了生产效率。
在本申请的一些实施例中，如图1和图2所示，第一翻边2与第一连接部12的数量相同且与第一连接部12一一对应连接，至少两个第一翻边2沿其周向间隔分布，且第一翻边2与第二连接部13之间形成有第二隔槽15，第二隔槽15在集流盘100的厚度方向上贯通设置，和/或第二翻边3与第一翻边2的数量相同且与第一翻边2一一对应连接，至少两个第二翻边3沿其周向间隔分布。通过设置与第一连接部12的数量相同且与第一连接部一一对应连接第一翻边2，且至少两个第一翻边2沿集流盘100周向间隔分布，使得集流盘100周向上具有多个定位点，提高了定位效果。通过在第一翻边2与第二连接部13之间形成贯通的第二隔槽15，使得第二连接部13靠近第一翻边2的一侧也能够相对主体部11弯曲一定角度，进一步提高了缓冲作用，降低第二连接部13与卷芯102的连接断开的几率。通过设置与第一翻边2的数量相同且与第一翻边2一一对应连接的第二翻边3，且至少两个第二翻边3沿其周向间隔分布，使得集流盘100上具有多个由第一翻边2和第二翻边3形成的弯折的弹性件，增强了缓冲效果。
如图7所示，根据本实用新型第二方面实施例的储能装置200，包括壳体101、卷芯102及上述实施例中的集流盘100，壳体101的至少一端设有开口，卷芯102容纳于壳体101内，集流盘100容纳于壳体101内，集流盘100通过第一翻边2扣在卷芯102的一端。
具体的，如图7所示，壳体101的至少一端设有开口，以便将卷芯102放入壳体101内。集流盘100通过第一翻边2扣在卷芯102的一端，集流盘100与卷芯102焊接时，两者发生错位，便于集流盘100与卷芯102的装配。在本申请方案中，储能装置200可以是电池单体，也可以是电池单体组成的电池模组、电池包和电池簇等。
根据本申请实施例的电池单体，通过采用上述的集流盘100，提高了电池单体的装配稳定性，提高了装配效率。
在一些实施例中，集流盘100包括第一集流盘和第二集流盘103，第一集流盘和第二集流盘103分别位于卷芯102的两端，第一集流盘和第二集流盘103的结构可以相同，也可以不同。
在一些实施例中，如图7所示，储能装置200还包括端盖104，端盖104封闭连接在开口上。
在一些实施例中，壳体101为铝制壳体101，端盖104与壳体101的开口通过激光焊接在一起。
在一些实施例中，如图7和图8所示，壳体101的一端设有开口且另一端为封闭端， 第二集流盘103对应封闭端设置，请结合图9，第二集流盘103的边缘具有第三翻边4以扣在卷芯102的端部。通过设置第三翻边4将第二集流盘103扣在卷芯102远离开口的一端，避免第二集流盘103与卷芯102连接时发生错位，便于第二集流盘103与卷芯102的装配。
具体的，如图9所示，第三翻边4与第二集流盘103的集流本体1垂直。第二集流盘103上的第二连接部13与第三翻边4连接。
