输出极连接片作为将电池电连接于外部装置的结构，在电池中占据重要地位。目前，为了固定安装输出极连接片，需要在端板上安装输出极底座，然后再通过输出极底座固定安装输出极连接片。
相关技术中，输出极底座包括底座本体和四个限位板。四个限位板分别固定于底座本体的四个角部，且与底座本体一体成型。在固定输出极连接片时，先将输出极连接片从相邻两个限位板之间穿过，然后通过螺栓等固定件将输出极连接片固定于输 出极底座，并将输出极底座固定于端板。
发明人发现，在固定输出极连接片时会产生扭力，而限位板为薄壁结构，在扭力作用或其他原因下较易损坏，如果将限位板与底座本体一体成型，限位板发生损坏时就需要将输出极底座整体从端板上拆卸下来，才能更换限位板，很不方便。另外，将限位板与底座本体一体成型，使得输出极底座只能用来固定单一规格的输出极连接片，普适性和可维护性比较低。而输出极连接片的规格较多，如果输出极底座不适用，则也需要将输出极底座整体从端板上拆卸下来，工作量和工作难度较大，且输出极底座的适用范围很局限。
基于此，本申请实施例提供一种输出极底座，该输出极底座的两个限位组件活动连接于底座本体沿第二方向的两端，移动限位组件便可以调整两个限位组件沿第二方向的间距，来适应不同规格的输出极连接片。并且，当限位组件损坏时，可以很方便地将限位组件从底座本体上拆卸下来并更换，并不需要将输出极底座整体从端板上拆卸下来再更换。因此，本申请实施例提供的输出极底座可以用来固定不同规格的输出极连接片，普适性较高，且可维护性较高，维护工作量和难度也较低。
在一些实施例中，如图1至图3所示，本申请实施例提供了一种输出极底座103，该输出极底座103包括底座本体1和两个限位组件2。底座本体1用于固定输出极连接片102并沿第一方向X固定在端板101上。两个限位组件2分别活动连接于底座本体1沿第二方向Y的两端，两个限位组件2沿第二方向Y的间距可调，两个限位组件2用于限制输出极连接片102的位置，第二方向Y与第一方向X垂直。
底座本体1可以是塑料或者塑胶材料制成，且底座本体1可以是注塑成型的塑料件或塑胶件，以便起到对输出极连接片102绝缘保护的作用。底座本体1沿第一方向X设置有装配孔，用于配合螺栓、销轴等固定件将输出极连接片102固定于底座本体1，并将底座本体1固定于端板101。这里需要说明的是，端板101一般位于电池单体104沿堆叠方向的两侧，用于抵抗电池单体104的膨胀力，此处的第一方向X可以与电池单体104的堆叠方向垂直。
两个限位组件2的结构可以相同。两个限位组件2可以以底座本体1的几何中心对称分布在底座本体1沿第二方向Y的两端，也可以不对称分布，本申请实施例对此不做限定。限位组件2活动连接于底座本体1，因此，限位组件2不仅可以安装于底座本体1，还可以从底座本体1拆卸下来。在将两个限位组件2安装于底座本体1时，可以根据所要固定的输出极连接片102沿第二方向Y的尺寸来调整两个限位组件2在第二方向Y上的间距。例如，当所要固定的输出极连接片102沿第二方向Y的尺寸为10mm时，可以将两个限位组件2沿第二方向Y的间距调整为10.5mm。
在调整两个限位组件2沿第二方向Y的间距时，可以将第一个限位组件2朝靠近/远离第二个限位组件2的方向移动，也可以将第二个限位组件2朝靠近/远离第一个限位组件2的方向移动，还可以将两个限位组件2同时相向移动/同时背向移动，以减小/增大两个限位组件2的间距，本申请实施例对此不做限定。
当两个限位组件2固定于底座本体1沿第二方向Y的两端时，可以在第二方向Y上限制输出极连接片102的位置，可以减少输出极连接片102相对底座本体1发生晃 动的可能，提高了电池100的安全性。
本申请实施例中，输出极底座103的两个限位组件2活动连接于底座本体1沿第二方向Y的两端，移动限位组件2便可以调整两个限位组件2沿第二方向Y的间距，来适应不同规格的输出极连接片102。并且，当限位组件2损坏时，可以很方便地将限位组件2从底座本体1上拆卸下来并更换，并不需要将输出极底座103整体从端板101上拆卸下来再更换。因此，本申请实施例提供的输出极底座103可以用来固定不同规格的输出极连接片102，普适性较高，且可维护性较高，维护工作量和难度也较低。
图4和图5示出了本申请实施例提供的输出极底座103固定不同规格的输出极连接片102的结构示意图。如图4所示，该输出极底座103中两个限位组件2沿第二方向Y的间距为L1，如图5所示，该输出极底座103中两个限位组件2沿第二方向Y的间距为L2。示例地，L1可以是22mm，L2可以是28mm，L1＜L2，图4中输出极底座103可以用来固定较窄的输出极连接片102，图5中输出极底座103可以用来固定较宽的输出极连接片102。
在一些实施例中，如图6和图7所示，限位组件2可以包括第一连接板21、第二连接板22以及限位板23。第一连接板21和第二连接板22沿第一方向X间隔设置，限位板23用于连接第一连接板21和第二连接板22的一端。第一连接板21、第二连接板22与限位板23之间形成容纳槽24，底座本体1沿第二方向Y的端部安装于容纳槽24。
第一连接板21和第二连接板22靠近限位板23的端部可以与限位板23朝向底座本体1的一侧连接。第一连接板21和第二连接板22可以平行设置，第一连接板21和第二连接板22沿第一方向X的间距可以根据底座本体1沿第二方向Y的端部的厚度来设置。其中，底座本体1沿第二方向Y的端部的厚度是底座本体1沿第二方向Y的端部在第一方向X上的尺寸。
限位板23沿第一方向X可以凸出于底座本体1背向端板101的一侧。这样，位于底座本体1沿第二方向Y的两端的两个限位板23可以在第二方向Y上限制输出极连接片102的位置。
第一连接板21和第二连接板22与限位板23之间形成的容纳槽24可以是U型的容纳槽24。底座本体1沿第二方向Y的端部可以部分容纳于容纳槽24，也可以全部容纳于容纳槽24，本申请实施例对此不做限定。当底座本体1沿第二方向Y的端部安装于容纳槽24时，第一连接板21朝向第二连接板22的表面可以与底座本体1朝向第一连接板21的表面贴紧，第二连接板22朝向第一连接板21的表面可以与底座本体1朝向第二连接板22的表面贴紧，这样，第一连接板21和第二连接板22可以将底座本体1沿第二方向Y的端部夹紧，从而提高限位组件2在底座本体1沿第二方向Y的端部的固定牢靠性。
限位组件2的限位板23与两个连接板之间形成容纳槽24，将底座本体1沿第二方向Y的端部安装于容纳槽24，便可实现限位组件2在底座本体1沿第二方向Y的端部的连接，连接方式简单易行，提高了连接限位组件2和底座本体1的效率。
在一些实施例中，如图6至图9所示，第二连接板22的一端可以与限位板23 转动连接。
示例地，第二连接板22靠近限位板23的端部可以与限位板23靠近底座本体1的一侧转动连接。
将第二连接板22的一端与限位板23转动连接，如图8和图9所示，在转动第二连接板22时，可以改变容纳槽24的槽口尺寸。示例地，如图8所示，当将第二连接板22向远离第一连接板21的方向转动时，可以增大容纳槽24的槽口尺寸；如图9所示，当将第二连接板22向靠近第一连接板21的方向转动时，可以减小容纳槽24的槽口尺寸。其中，容纳槽24的槽口是第一连接板21未与限位板23连接的端部，以及第二连接板22未与限位板23连接的端部之间形成的开口。
在需要将限位组件2安装于底座本体1沿第二方向Y的两端时，可以先将第二连接板22向远离第一连接板21的方向转动，增大容纳槽24的槽口尺寸。然后，将底座本体1沿第二方向Y的端部伸入安装槽。最后，将第二连接板22向靠近第一连接板21的方向转动，减小容纳槽24的槽口尺寸，以将底座本体1沿第二方向Y的端部夹紧在容纳槽24中。
将第二连接板22的一端与限位板23转动连接，可以很方便地通过转动第二连接板22来调节容纳槽24的槽口尺寸，从而便于将底座本体1沿第二方向Y的两端安装于容纳槽24，实现底座本体1与限位组件2的活动连接。基于此，可以将底座本体1沿第二方向Y的端部与容纳槽24的配合方式设置为过盈配合，在不增加安装难度的同时可以提高底座本体1和限位组件2连接的牢靠性。
为了实现第二连接板22与限位板23的转动连接，在一些实施例中，限位板23上可以设置有第一合页片，第二连接板22上可以设置有第二合页片，限位板23和第二连接板22可以通过包含第一合页片和第二合页片的合页结构实现转动连接。
在另一些实施例中，限位板23和第二连接板22可以通过轴孔结构实现转动连接。
示例地，如图10所示，限位板23可以设置有固定轴231，第二连接板22的一端具有安装孔221，固定轴231插入安装孔221，以将第二连接板22转动连接在限位板23上。
固定轴231可以是限位板23靠近第二连接板22的端部沿第二方向Y设置的。安装孔221可以是第二连接板22靠近限位板23的端部沿第二方向Y设置的。安装孔221和固定轴231的横截面形状可以是圆形、方形、菱形、三角形等，只要安装孔221与固定轴231相匹配，使得固定轴231可以插入安装孔221，并不会轻易从安装孔221滑脱即可，本申请实施例对此不做限定。
本实施例中，将固定轴231插入安装孔221，便可以将第二连接板22转动连接在限位板23上，连接方式简单，可操作性强。
在一些实施例中，如图2所示，底座本体1沿第二方向Y的端部朝向第一连接板21的表面设置有至少一个第一限位结构11，第一连接板21朝向底座本体1的表面设置有至少一个第二限位结构211，第一限位结构11和第二限位结构211互相配合，底座本体1和限位组件2通过第一限位结构11和第二限位结构211活动连接。
如图11所示，底座本体1沿第二方向Y可以包括第一端部12、第二端部13和中间部14，第一端部12和第二端部13位于中间部14的两侧。第一端部12和第二端部13均可以设置有第一限位结构11。
以第一端部12为例，第一端部12设置的第一限位结构11的数量可以与第一连接板21设置的第二限位结构211的数量相同，当然也可以不相同。
当第一端部12设置的第一限位结构11为一个时，这个第一限位结构11可以设置在第一端部12的任意位置，例如，可以设置在第一端部12靠近中间部14的部位，也可以设置在第一端部12远离中间部14的部位。当第一连接板21设置的第二限位结构211为一个时，这个第二限位结构211可以设置在第一连接板21的任意位置，例如，可以设置在第一连接板21靠近底座本体1的中间部14的一侧，也可以设置在第一连接板21远离该中间部14的一侧。只要满足第一限位结构11和第二限位结构211互相配合，可以将底座本体1和限位组件2活动连接起来即可，本申请实施例对此不做限定。
当第一限位结构11和第二限位结构211为多个时，多个第一限位结构11和多个第二限位结构211的配合关系可调。例如，可以将靠近外侧的第一限位结构11与靠近内侧的第二限位结构211配合，也可以将靠近内侧的第一限位结构11与靠近外侧的第二限位结构211配合。当将靠近外侧的第一限位结构11与靠近内侧的第二限位结构211配合时，可以调大两个限位组件2沿第二方向Y的间距；当将靠近内侧的第一限位结构11与靠近外侧的第二限位结构211配合时，可以调小两个限位组件2沿第二方向Y的间距。其中，外侧指的是远离底座本体1的中间部14的一侧，内侧指的是靠近底座本体1的中间部14的一侧。
本实施例中，底座本体1和限位组件2可以通过第一限位结构11和第二限位结构211活动连接。当第一限位结构11和第二限位结构211为多个时，调整多个第一限位结构11和多个第二限位结构211的配合关系，可以调整两个限位组件2沿第二方向Y的间距，有利于增大输出极底座103的适用范围。
在此需要说明的是，为了实现底座本体1和限位组件2的活动连接，本申请实施例还可以将第一限位结构11设置在底座本体1沿第二方向Y的端部朝向第二连接板22的表面，将第二限位结构211设置在第二连接板22朝向底座本体1的表面。本申请实施例对第一限位结构11和第二限位结构211的设置位置不做限定。
在一些实施例中，如图2、图6、图7、图11所示，第一限位结构11和第二限位结构211中的一者为滑槽，另一者为滑轨。
以底座本体1的第一端部12为例，如图2和图11所示，第一限位结构11可以是第一端部12的上表面向下表面凹陷形成的滑槽，第二限位结构211可以是第一连接板21的下表面朝第二连接板22凸起形成的滑轨。或者，第一限位结构11可以是第一端部12的上表面朝向第一连接板21凸起形成的滑轨，第二限位结构211可以是第一连接板21的下表面向上表面凹陷形成的滑槽。其中，第一端部12的上表面是第一端部12朝向第一连接板21的表面，第一端部12的下表面是第一端部12朝向第二连接板22的表面；第一连接板21的上表面是第一连接板21背向第二连接板22的表面， 第一连接板21的下表面是第一连接板21朝向第二连接板22的表面。
将第一限位结构11和第二限位结构211中的一者设置为滑槽，另一者设置为滑轨，使得第一限位结构11和第二限位结构211中的一者可以沿另一者滑动，从而可以通过滑动的方式在底座本体1上活动连接或拆卸限位组件2，拆装方式简单易行，可以提高限位组件2的拆装效率。
在一些实施例中，如图2、图6、图7、图11所示，第一限位结构11和第二限位结构211沿第三方向Z延伸设置；或者，第一限位结构11和第二限位结构211沿第二方向Y延伸设置，图中未示出。其中，第一方向X、第二方向Y、第三方向Z相互垂直。
当第一限位结构11和第二限位结构211沿第三方向Z延伸设置时，限位组件2可以沿第三方向Z活动连接于底座本体1沿第二方向Y的端部。当第一限位结构11和第二限位结构211沿第二方向Y延伸设置时，限位组件2可以沿第二方向Y活动连接于底座本体1沿第二方向Y的端部。本申请实施例对第一限位结构11和第二限位结构211的延伸方向不做限定。
通过上述方案，可以将限位组件2沿第二方向Y活动连接于底座本体1沿第二方向Y的端部，也可以将限位组件2沿第三方向Z活动连接于底座本体1沿第二方向Y的端部，使得限位组件2与底座本体1的连接更加灵活多样。
在一些实施例中，如图2和图3所示，该输出极底座103还可以包括卡接板3。卡接板3沿第一方向X凸出于底座本体1背向端板101的一侧，卡接板3固定在第二连接板22远离限位板23的端部，用于限制输出极连接片102的位置。
卡接板3可以在底座本体1沿第二方向Y的端部安装于容纳槽24之后固定在第二连接板22远离限位板23的端部，也可以先将卡接板3固定在第二连接板22远离限位板23的端部，再将底座本体1沿第二方向Y的端部安装于容纳槽24，本申请实施例对此不做限定。
当底座本体1沿第二方向Y的端部安装于容纳槽24时，卡接板3可以平行于限位板23。
卡接板3沿第一方向X凸出于底座本体1背向端板101的一侧，使得卡接板3可以配合限位板23沿第三方向Z限制输出极连接片102的位置。当底座本体1沿第二方向Y的两端均设置有卡接板3，且这两个卡接板3沿第一方向X均凸出于底座本体1背向端板101的一侧时，这两个卡接板3可以沿第三方向Z限制输出极连接片102的位置。
在一些实施例中，如图6和图7、图12所示，第二连接板22远离限位板23的端部可以设置有弹性部222，卡接板3与弹性部222相对的部位设置有卡槽31，弹性部222与卡槽31互相配合。
弹性部222可以是卡扣，弹性部222可以卡入卡槽31，并与卡槽31卡接配合。弹性部222可以采用耐磨性较好的材料制成，例如，弹性部222可以是金属材质。这样，可以延长弹性部222的使用寿命。弹性部222也可以是采用与第二连接板22相同的材质制成，如塑料或橡胶材质。这样，弹性部222可以与第二连接板22一体成型， 便于降低制造工艺成本。
如图13所示，弹性部222可以包括第一弹性悬臂222a和第二弹性悬臂222b，第一弹性悬臂222a和第二弹性悬臂222b均包括相对的固定端和自由端。第一弹性悬臂222a的固定端和第二弹性悬臂222b的固定端均固定连接在第二连接板22远离限位板23的端部，第一弹性悬臂222a的自由端和第二弹性悬臂222b的自由端均朝卡接板3延伸。
向第一弹性悬臂222a和第二弹性悬臂222b的自由端施加相向的作用力时，第一弹性悬臂222a的自由端和第二弹性悬臂222b的自由端相互靠近，弹性部222得以伸入卡槽31。第一弹性悬臂222a和第二弹性悬臂222b具有弹性，在自身弹性作用下，如图14和图15所示，第一弹性悬臂222a的自由端和第二弹性悬臂222b的自由端可以与卡槽31卡接并维持该卡接状态，从而实现卡接板3与第二连接板22的连接。
在此需要说明的是，为了提高卡接板3与第二连接板22的连接强度，弹性部222的数量可以为多个，且可以间隔分布在第二连接板22远离限位板23的端部。相应地，卡槽31的数量也可以为多个，且多个卡槽31与多个弹性部222一一相对。
本实施例中，将弹性部222卡进卡槽31便可以实现卡接板3与第二连接板22的连接，连接方式简单可靠，可以提高输出极底座103的装配效率。
在一些实施例中，如图13至图15所示，第二连接板22远离限位板23的端部可以设置有定位柱223，如图12所示，卡接板3与定位柱223相对的部位设置有定位孔32，定位柱223与定位孔32互相配合。
定位柱223可以是空心柱状结构，也可以是实心柱状结构。定位柱223的横截面形状可以是圆形、方形、菱形、三角形等。定位柱223的横截面是定位柱223沿第一方向X的截面。
定位柱223沿第三方向Z的尺寸可以大于弹性部222沿第三方向Z的尺寸，这样，当卡接板3向第二连接板22靠近，以在第二连接板22远离限位板23的端部固定卡接板3时，定位柱223可以先进入定位孔32，为卡接板3与第二连接板22的装配提供位置导向，便于弹性部222快速准确地插入卡槽31。
定位柱223的设置，可以为卡接板3与第二连接板22的装配提供位置导向，便于弹性部222快速准确地插入卡槽31。另外，当底座本体1沿第二方向Y的两端均具有定位柱223时，如果底座本体1相对端板101发生晃动或旋转时，定位柱223可以承受部分力，有效减少作用于弹性部222的力，从而可以减小对弹性部222这种易损件的损伤，延长输出极底座103的使用寿命。
在一些实施例中，如图12所示，卡接板3朝向底座本体1的一面可以设置有卡接部33，卡接部33卡在第一连接板21背向底座本体1的表面上。
卡接部33可以是凸出于卡接板3朝向底座本体1的一面的凸台，该凸台可以沿第二方向Y延伸设置。沿第二方向Y，该凸台的尺寸可以小于或等于卡接板3的尺寸。
将卡接部33卡在第一连接板21背向底座本体1的表面上，便于将底座本体1沿第二方向Y的端部夹紧在容纳槽24中，减少限位组件2相对于底座本体1发生 晃动的可能。
进一步地，在一些实施例中，如图6和图7所示，第一连接板21背向底座本体1的表面在靠近卡接板3的一侧可以设置有向第二连接板22凹陷的卡接槽212，卡接部33可以卡在该卡接槽212内来锁紧限位组件2和底座本体1。这种情况下，卡接部33背向第二连接板22的一侧可以与第一连接板21背向第二连接板22的表面在第一方向X上平齐，从而可以在第三方向Z上为输出极连接片102提供更大的空间，减少因卡接部33凸出于第一连接板21背向第二连接板22的表面而对输出极连接片102产生干涉的可能。
根据本申请的一些实施例，如图1、图4和图5所示，本申请实施例还提供一种电池100，包括多个电池单体104、端板101、输出极连接片102和前面实施例中的输出极底座103。端板101用于限制多个电池单体104的位置；输出极底座103沿第一方向X固定于端板101上；输出极连接片102固定于输出极底座103。
本申请实施例中的电池100是指包括一个或多个电池单体104以提供更高的电压和容量的单一的物理模块。例如，本申请中所提到的电池100可以包括电池模块或电池包等。且本申请中所提到的电池单体104可以是圆柱电池单体或方形电池单体或其他各种形状的电池单体104。
根据本申请的一些实施例，本申请实施例还提供一种用电装置，包括前面实施例中的电池100，并且电池100用于为用电装置提供电能。
用电装置可以是汽车、手机、便携式设备、笔记本电脑、轮船、航天器、电动玩具和电动工具等等。汽车可以是燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等；航天器包括飞机、火箭、航天飞机和宇宙飞船等等；电动玩具包括固定式或移动式的电动玩具，例如，游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等；电动工具包括金属切削电动工具、研磨电动工具、装配电动工具和铁道用电动工具，例如，电钻、电动砂轮机、电动扳手、电动螺丝刀、电锤、冲击电钻、混凝土振动器和电刨等等。本申请实施例对上述用电装置不做特殊限制。
根据本申请的一些实施例，参见图1至图9，本申请提供了一种输出极底座103，包括底座本体1、两个限位组件2和两个卡接板3。底座本体1用于固定输出极连接片102并沿第一方向X固定在端板101上。两个限位组件2分别活动连接于底座本体1沿第二方向Y的两端，两个卡接板3分别活动连接在两个限位组件2的端部。两个限位组件2沿第二方向Y的间距可调，且两个限位组件2具有容纳槽24。当底座本体1沿第二方向Y的端部安装于容纳槽24内后，卡接板3可以将底座本体1沿第二方向Y的端部锁紧在容纳槽24内，以将限位组件2连接于底座本体1。
本领域的技术人员能够理解，尽管在此的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本申请的范围之内并且形成不同的实施例。例如，在权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
