一种防护组件、电池及用电设备
本申请要求于2022年01月25日提交国家知识产权局、申请号为202220203578.7、申请名称为“一种防护组件、电池及用电设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电化学装置技术领域，特别是涉及一种防护组件、电池及用电设备。
 背景技术
节能减排是汽车产业可持续发展的关键，电动车辆由于其节能环保的优势成为汽车产业可持续发展的重要组成部分。对于电动车辆而言，电池技术又是关乎其发展的一项重要因素。
相关技术中，在电池内部设置有许多元器件，元器件之间可通过各元器件的导电件实现电连接，元器件的导电件一般为金属件，如铜巴等。在电池的拆装和使用中，会使导电件部分裸露。由于导电件具有电传导特性，裸露的导电件会产生安全隐患，降低电池的安全性能。
 技术问题
本申请实施例的目的在于提供一种防护组件、电池及用电设备，以降低电池内元器件的导电件裸露的概率，提高电池的安全性能。
 技术解决方案
本申请第一方面的实施例提供了一种防护组件，防护组件应用于电池的转接装置，转接装置包括转接导电件，防护组件包括主体部、保护盖、连接件和限位件。保护盖与主体部滑动连接，保护盖可沿转接导电件的延伸方向移动；连接件与保护盖固定连接；限位件与主体部连接，且限位件与连接件压接，限位件可沿竖直方向移动；限位件沿竖直方向移动，使连接件及保护盖沿转接导电件的延伸方向移动，且保护盖至少部分覆盖转接导电件的一端。
本申请实施例的技术方案中，转接装置的转接导电件设置于转接装置主体上，且转接装置上包括用于与电池内元器件的连接端。保护盖与主体部滑动连接且可沿转接导电件的延伸方向移动，也就是保护盖可朝向转接导电件的连接端移动，从而部分或完全覆盖转接导电件的连接端，以对连接端及与连接端连接的其他元器件的导电件进行保护。此外，由于限位件可沿竖直方向移动且与连接件压接，当限位件受到外界提供的向下的力时，限位件沿竖直方向向下移动，使连接件在压力的作用下沿转接导电件的延伸方向移动。由于连接件与保护盖固定连接，连接件带动保护盖沿转接导电件的延伸方向移动，具体为沿远离转接导电件的连接端的方向移动，从而使连接端至少部分露出以与电池内其他元器件连接。也就是，防护组件可在转接装置需要与元器件连接时将转接导电件的连接端露出，且保护盖可移动至连接端的上方以对连接端及与连接端连接的元器件的导电件进行保护，降低元器件的导电件裸露的概率，提高电池的安全性能。
一些实施例中，防护组件还包括导轨，导轨设置于主体部上且延伸方向平行于转接导电件的延伸方向，保护盖与导轨滑动连接。保护盖通过导轨与主体部实现滑动连接，使其可快速的遮挡保护转接导电件的连接端及元器件的导电件，保护盖可与导轨卡接，使得保护盖的安装便捷，且保护盖不易于由导轨及主体部上脱落，连接稳定性较高。
一些实施例中，防护组件还包括第一导杆，第一导杆沿竖直方向设置，第一导杆的一端与主体部固定连接，限位件与第一导杆滑动连接。第一导杆在限位件移动过程中为限位件进行导向，限制限位件沿水平方向移动的趋势。
一些实施例中，第一导杆的远离主体部的一侧侧面上设置有凸起结构。由此，凸起结构限制了限位件沿竖直方向的移动距离，降低了限位件因向上移动距离过大而由第一导杆上脱落的概率。
一些实施例中，防护组件还包括第二导杆和弹性元件，第二导杆的两端与主体部固定连接，且第二导杆平行于转接导电件的延伸方向设置；弹性元件套接于第二导杆外，且连接件的远离限位件的一侧与弹性元件的一端抵接。弹性元件的反弹力可推动连接件及保护盖沿靠近连接端及元器件的导电件的方向移动，使得保护盖可快速移动至元器件的导电件的上方并对其进行遮挡，进一步降低元器件的导电件裸露的概率，提高电池的安全性能。
一些实施例中，连接件靠近限位件的一侧表面为倾斜面；和/或限位件靠近连接件的一侧表面为倾斜面。倾斜面的设置可以使得在限位件沿竖直方向向下移动的过程中，连接件在限位件提供的推动力的作用下可以沿导轨的延伸方向移动。
一些实施例中，主体部与转接装置固定连接，且主体部和转接装置连接方式包括一体注塑。主体部和转接装置一体注塑，可以提高防护组件和转接装置的连接紧固性，且可以简化制造工艺。
一些实施例中，保护盖为塑料件。保护盖用于覆盖转接导电件，塑料件具有良好的绝缘性，且塑料件可以根据使用要求加工成多种形状的产品，满足复杂的加工要求，且加工工艺简单，成本较低。
本申请第二方面的实施例提供了一种电池，电池包括上述实施例中任一所述的防护组件，防护组件应用于电池的转接装置。
本申请第三方面的实施例提供了一种用电设备，用电设备包括上述实施例中的电池，电池用于向用电设备提供电能。

节能减排是汽车产业可持续发展的关键，电动车辆由于其节能环保的优势成为汽车产业可持续发展的重要组成部分。对于电动车辆而言，电池技术又是关乎其发展的一项重要因素。相关技术中，在电池内部设置有许多元器件，如高压盒等。高压盒具有用于将内部电路引出以与其他元器件连接的导电件，即高压铜巴。而在电池的拆装和使用中，高压盒的高压铜巴处于裸露状态，易于产生安全隐患，影响电池的安全性能。
目前，对高压盒等元器件的高压铜巴的防护方式多为用绝缘胶带将高压铜巴的裸露部位包缠隔离。但在高压铜巴外包缠绝缘胶带不但费时，而且绝缘胶带相比高压盒也易老化，具有安全风险。随后采用高压铜巴保护盖结构对高压铜巴进行防护，目前的高压铜巴保护盖与高压盒壳体或高压铜巴等多采用卡扣连接，在通过保护盖对高压铜巴进行防护的过程中，保护盖易于出现脱落或保护盖的连接卡扣断裂等现象，使得高压铜巴裸露，产生安全隐患。
基于以上考虑，为了降低电池内元器件的导电件裸露的概率，提高电池的安全性能，发明人经过深入研究，设计了一种防护组件。即本申请实施例提供的防护组件，通过限位件沿竖直方向移动带动连接件及防护组件相对于主体部滑动，且滑动方向为转接导电件的延伸方向，从而使保护盖沿远离或靠近转接导电件的连接端的方向移动，从而使保护盖部分或完全覆盖转接导电件的连接端，对连接端及与连接端连接的其他元器件的导电件进行保护，提高降低电池内元器件的导电件裸露的概率，提高电池的安全性能。
本申请实施例提供一种使用包括上述防护组件的电池作为电源的用电设备，用电设备可以为但不限于手机、便携式设备、笔记本电脑、电瓶车、电动汽车、轮船、航天器、电动玩具和电动工具等，例如，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。

本申请实施例中，电池2还包括电池箱体5(或称罩体)，电池箱体5内部具有容纳空间，多个电池单体6容纳于容纳空间内。如图2所示，电池箱体5可以包括两部分，这里分别称为第一部分51和第二部分52。第一部分51和第二部分52可通过扣合、粘接等方式连接，以形成容纳空间。多个电池单体6相互并联或串联或混联组合后置于第一部分51和第二部分52连接后形成的电池箱体5内。其中，第一部分51和第二部分52的形状可以根据多个电池单体6组合而成的形状确定。
其中，电池箱体5用于对至少一个电池单体6进行保护，从而降低电池2外部的液体或其他异物对至少一个电池单体6的充电或放电的影响。其中，电池单体6可呈圆柱体、扁平体、长方体或其它形状等，本申请实施例对此不作限定。电池单体6的封装方式包括但不限于柱形电池单体、方体方形电池单体和软包电池单体等，本申请实施例对此也不作具体限定。

本申请第一方面的实施例提供了一种防护组件8，请参照图3和图4，防护组件8应用于电池2的转接装置7，转接装置7包括转接导电件71，防护组件8包括主体部81、保护盖82、连接件83和限位件84。保护盖82与主体部81滑动连接，保护盖82可沿转接导电件71的延伸方向移动。连接件83与保护盖82固定连接；限位件84与主体部81连接，且限位件84与连接件83压接，限位件84可沿竖直方向移动。限位件84沿竖直方向移动，使连接件83及保护盖82沿转接导电件71的延伸方向移动，且保护盖82至少部分覆盖转接导电件71的一端。
本申请实施例中，转接装置7为固定于电池箱体5内部，用于在电池2内的元器件之间实现电连接的组件，例如，转接装置7可设置于电池模组或电池单体6与高压盒之间，实现电池模组或电池单体6与高压盒的电连接。转接导电件71设置于转接装置7主体上，转接导电件71具有至少两个连接端72，至少两个连接端72用于分别与元器件的导电件连接，实现元器件之间的电传导。例如，转接导电件71的一个连接端72可与电池模组连接，另一个连接端72可与高压盒的高压铜巴连接，且如图3所示，连接端72与高压铜巴压接后可通过紧固件固定连接。其中，紧固件包括但不限于螺栓、螺钉等。此外，转接导电件71的材料包括但不限于铜、铝等，转接装置7主体的材料包括但不限于塑料、橡胶等。
本申请实施例中，主体部81为防护组件8的主要组成部分，主体部81可以用于支撑固定防护组件8的各个结构，如保护盖82、连接件83及限位件84等。主体部81的材料可以为塑胶、塑料或具有绝缘层的金属等，本申请实施例对此不作限定。转接导电件71的延伸方向为靠近或远连接端72的方向，如图3中S方向。为便于描述，下面将转接导电件71的延伸方向简称为第一方向。
本申请实施例中，保护盖82与主体部81滑动连接，保护盖82可沿靠近连接端72的方向移动，以对连接端72进行遮挡及保护。其中，转接导电件71的连接端72所在的位置也就是与其连接的元器件的导电件所在的位置，因此保护盖82用于遮挡及保护元器件的导电件，如高压盒的高压铜巴。保护盖82整体可以为凹槽状，如图4所示，保护盖82可以包括两个相对平行设置的侧壁及连接两个侧壁的顶壁，两个侧壁与顶壁共同形成遮挡容纳空间，转接导电件71的连接端72可置于遮挡容纳空间内。此外保护盖82还可以为平板状、弧面状等，本申请对此不作具体限定。
本申请实施例中，连接件83与保护盖82固定连接，用于带动保护盖82沿转接导电件71的延伸方向移动。限位件84与连接件83压接，限位件84用于在向下移动时为连接件83提供向下的压力及平行于第一方向的推动力，从而使连接件83及与其固连的保护盖82可沿第一方向移动，具体的，沿远离连接端72的方向移动。此外，连接件83沿靠近连接端72的方向移动时，连接件83还用于向限位件84提供向上的驱动力，使限位件84沿竖直方向向上移动。其中连接件83和限位件84的材料可包括塑料、金属等，本申请实施例对此不作限定。
本申请实施例的技术方案中，如图4所示，转接装置7的转接导电件71设置于转接装置7的主体上，且转接装置7包括用于与电池2内元器件连接的连接端72。保护盖82与主体部81滑动连接且可沿转接导电件71的延伸方向移动，也就是保护盖82可朝向转接导电件71的连接端72移动，从而部分或完全覆盖转接导电件71的连接端72，以对连接端72及与连接端72连接的其他元器件的导电件进行保护。此外，由于限位件84可沿竖直方向移动且与连接件83压接，当限位件84受到外界提供的向下的力时，限位件84沿竖直方向向下移动，使连接件83在压力的作用下沿转接导电件71的延伸方向移动。由于连接件83与保护盖82固定连接，连接件83带动保护盖82沿转接导电件71的延伸方向移动，具体为沿远离转接导电件71的连接端72的方向移动，从而使连接端72至少部分露出以与电池2内其他元器件连接。也就是，防护组件8可在转接装置7需要与元器件连接时将转接导电件71的连接端72露出，且保护盖82可移动至连接端72的上方以对连接端72及与连接端72连接的元器件的导电件进行保护，降低元器件的导电件裸露的概率，提高电池2的安全性能。
此外，与相关技术中卡扣连接的保护盖82相比，本申请实施例提供的保护盖82与主体部81滑动连接，降低了在使用过程中卡扣掉落导致元器件带电的导电件裸露的概率，提高了电池2的安全性。
根据本申请的一些实施例，请参照图4，防护组件8还包括导轨85，导轨85设置于主体部81上且延伸方向平行于转接导电件71的延伸方向，保护盖82与导轨85滑动连接。
本申请实施例中，导轨85为设置于主体部81上，且在保护盖82滑动过程中为保护盖82进行导向的结构。导轨85的延伸方向也就是保护盖82相对主体部81的滑动方向，即导轨85的延伸方向为第一方向（图4中箭头所示的方向）。导轨85可以为U型导轨或T型导轨等，本申请对此不作限定。进一步的，导轨85也可以为沿第一方向延伸的导杆，保护盖82可以套接于导杆并与导杆滑动连接。导轨85的材料可以为金属、塑料或塑胶等，本申请对此也不作具体限定。当导轨85及主体部81的材料均为塑料或塑胶时，导轨85及主体部81可一体注塑成型，以降低防护组件8制作工艺的复杂度。
本申请实施例中，保护盖82通过导轨85与主体部81实现滑动连接，保护盖82可与导轨85卡接，使得保护盖82的安装便捷，且保护盖82不易于由导轨85及主体部81上脱落，连接稳定性较高。保护盖82通过导轨85相对于主体部81沿第一方向滑动，减小了保护盖82滑动过程中与主体部81的摩擦力，加快保护盖82的移动速度，使其可快速遮挡保护转接导电件71的连接端72及元器件的导电件。
根据本申请的一些实施例，请参照图4、图5和图7，防护组件8还包括第一导杆86，第一导杆86沿竖直方向设置，第一导杆86的一端与主体部81固定连接，限位件84与第一导杆86滑动连接。
本申请实施例中，如图5所示，第一导杆86为设置于主体部81上，且在限位件84移动过程中为限位件84进行导向的结构。第一导杆86的延伸方向也就是限位件84的移动方向，即第一导杆86的延伸方向为竖直方向。第一导杆86可以为圆形导杆或半圆形导杆，本申请对此不作限定。进一步的，第一导杆86也可以为沿竖直方向延伸的导轨结构，限位件84可以卡接于导轨结构并与导轨结构滑动连接。第一导杆86的材料可以为金属、塑料或塑胶等，本申请对此也不作具体限定。当第一导杆86及主体部81的材料均为塑料或塑胶时，第一导杆86及主体部81可一体注塑成型，以降低防护组件8制作工艺的复杂度。
本申请实施例中，限位件84通过第一导杆86与主体部81实现滑动连接，限位件84可套接于第一导杆86上，使得限位件84的安装便捷，且限位件84不易于由第一导杆86及主体部81上脱落，连接稳定性较高。第一导杆86在限位件84移动过程中为限位件84进行导向，限制了限位件84沿水平方向移动的趋势。
根据本申请的一些实施例，请参照图4、图6和图7，第一导杆86的远离主体部81的一侧侧面上设置有凸起结构87。
本申请实施例中，如图6所示，凸起结构87为设置于导杆外侧表面上且沿远离导杆的方向凸起的结构。用于限制限位件84沿竖直方向的移动距离。凸起结构87的形状可以与第一导杆86相适配，即凸起结构87可以为绕第一导杆86外侧周向设置的环状凸起，提升对限位件84的限位效果。此外，凸起结构87还可以为段状凸起或点状凸起，本申请对此不作限定。凸起结构87与第一导杆86可以为一体结构。凸起结构87可设置于导杆的顶端外侧，也可以设置于导杆外侧的其他位置，可根据实际需求进行调整，如根据所需的限位件84的移动距离进行调整，本申请对此不作具体限定。
本申请实施例中，第一导杆86的一端与主体部81固定连接，另一端的侧面上设置有凸起结构87，主体部81及凸起结构87限定出限位件84沿竖直方向的移动距离。具体的，当限位件84通过第一导杆86向下移动时，主体部81可以限制限位件84继续向下移动，当限位件84通过第一导杆86向上移动时，凸起结构87可以限制限位件84继续向上移动，防止限位件84脱离第一导杆86。
根据本申请的一些实施例，请参照图4、图7和图8，防护组件8还包括第二导杆88和弹性元件89，第二导杆88的两端与主体部81固定连接，且第二导杆88平行于转接导电件71的延伸方向设置；弹性元件89套接于第二导杆88外，且连接件83的远离限位件84的一侧与弹性元件89的一端抵接。
本申请实施例中，如图8所示，第二导杆88用于支撑弹性元件89，第二导杆88可以内嵌于主体部81内，此时可通过位于第二导杆88两端的主体部81对弹性元件89进行限位，第二导杆88两端也可以设置环状凸起，以对弹性元件89进行限位，降低弹性元件89由第二导杆88上脱落的概率。第二导杆88也可以与主体部81卡接或锁付连接，本申请实施例对此不作限定。
弹性元件89为通过自身的弹力及反弹力带动与其连接的连接件83移动的结构。弹性元件89包括但不限于弹簧、弹片等。
本申请实施例中，防护组件8具有第一工作状态及第二工作状态。下面以与转接装置7连接的元器件为高压盒为例对防护组件8的工作状态进行说明。当元器件为高压盒时，防护组件8上的限位件84可以与高压盒的上壳体连接。
第一工作状态时，限位件84受到向下的压力而沿竖直方向向下移动，且向下移动的过程中提供给连接件83一个沿第一方向的推动力，使得连接件83带动保护盖82沿第一方向移动，具体为沿远离连接端72的方向移动，从而使转接导电件71的连接端72至少部分裸露，此时连接端72可以与高压盒上的导电片连接。并且在连接件83移动的过程中压缩弹性元件89，使其处于压缩状态。其中，限位件84可以与高压盒的上壳体连接，高压盒上壳体向下闭合与下壳体连接时，上壳体可以给予限位件84向下的力，限位件84通过第一导杆86沿竖直方向向下移动。
第二工作状态时，限位件84受到的向下的力撤销，连接件83受到的沿第一方向的推动力减小直至消失，此时弹性元件89受到的压缩力减小至小于弹性元件89的反弹力，使得弹性元件89的反弹力能够推动连接件83及保护盖82沿第一方向移动，具体为沿靠近连接端72的方向移动，从而使保护盖82至少部分遮盖转接导电件71的连接端72，此时弹性元件89处于自然状态。例如，在限位件84与高压盒的上壳体连接的情况下，当高压盒或高压盒内部元器件需要维修更换时，高压盒的上壳体打开，限位件84不再受到上壳体提供的向下的压力，此时在弹性元件89反弹力的作用下，保护盖82移动并至少部分遮盖转接导电件71的连接端72及高压盒的导电件，降低维护更换人员误触而发生安全隐患的概率。
本申请实施例中，弹性元件89的反弹力可驱动连接件83及保护盖82沿靠近连接端72及元器件的导电件的方向移动，使得保护盖82可快速移动至元器件的导电件的上方并对其进行遮挡，进一步降低元器件的导电件裸露的概率，提高电池2的安全性能。
根据本申请的一些实施例，请参照图3、图4和图5，连接件83靠近限位件84的一侧表面为倾斜面；和/或限位件84靠近连接件83的一侧表面为倾斜面。
本申请实施例中，如图5所示，连接件83靠近限位件84的一侧表面为倾斜面时，且连接件83倾斜面上的最低点相较于最高点更靠近第一导杆86设置。限位件84表面靠近连接件83的一侧表面为倾斜面时，限位件84倾斜面上的最低点相较于最高点更远离第一导杆86设置。倾斜面可以使限位件84在沿竖直方向向下移动时，使与限位件84压接的连接件83可以沿第一方向移动。也可以使连接件83沿第一方向移动时，使与连接件83压接的限位件84可以沿竖直方向向上移动。
本申请实施例中，当连接件83靠近限位件84的一侧表面为倾斜面，此时限位件84靠近连接件83的一侧表面可以为倾斜面，也可以为其他形态的表面，例如圆形、方形等，本申请实施例对此不作限定。当限位件84靠近连接件83的一侧表面为倾斜面时，连接件83表面靠近限位件84的一侧表面可以为倾斜面，也可以为其他形态的表面，本申请实施例对此不作限定。
进一步的，连接件83靠近限位件84的一侧表面为倾斜面时，限位件84靠近连接件83的一侧表面可以为与连接件83的倾斜面互补的倾斜面。此时在限位件84提供的沿第一方向的推动力的作用下，连接件83沿第一方向移动；以及连接件83在弹性元件89的反弹力作用下推动限位件84沿竖直方向移动的效率较高。
根据本申请的一些实施例，请参照图3，主体部81与转接装置7固定连接，且主体部81和转接装置7连接方式包括一体注塑。
本申请实施例中，如图3所示，主体部81和转接装置7一体注塑，可以保证防护组件8和转接装置7的连接紧固性，也可以简化制造工艺，降低生产成本。主体部81和转接装置7主体部81还可以通过粘接、卡接和锁付连接等方式固定连接，本申请实施例对此不作限定。主体部81和转接装置7主体的材料都可以为塑料，使用塑料材料不仅能够降低成本，提高绝缘性，还可以满足复杂的制造工艺要求。
根据本申请的一些实施例，保护盖82为塑料件。
本申请实施例中，保护盖82用于覆盖转接导电件71，塑料件具有良好的绝缘性，且塑料件可以根据使用要求加工成多种形状的产品，满足复杂的加工要求，且加工工艺简单，成本较低。
本申请第二方面的实施例提供了一种电池2，电池2包括上述实施例中任一所述的防护组件8，防护组件8应用于电池2的转接装置7。
本申请实施例的技术方案中提出的一种使用防护组件8的电池2中，转接装置7的转接导电件71设置于转接装置7主体上，且转接装置7包括用于与电池2内元器件的连接端72。保护盖82与主体部81滑动连接且可沿转接导电件71的延伸方向移动，也就是保护盖82可朝向转接导电件71的连接端72移动，从而部分或完全覆盖转接导电件71的连接端72，以对连接端72及与连接端72连接的其他元器件的导电件进行保护。此外，由于限位件84可沿竖直方向移动且与连接件83压接，当限位件84受到外界提供的向下的力时，限位件84沿竖直方向向下移动，使连接件83在压力的作用下沿转接导电件71的延伸方向移动。由于连接件83与保护盖82固定连接，连接件83带动保护盖82沿转接导电件71的延伸方向移动，具体的沿远离转接导电件71的连接端72的方向移动，从而使连接端72至少部分露出以与电池2内其他元器件连接。也就是，防护组件8可在转接装置7需要与元器件连接时将转接导电件71的连接端72露出，且保护盖82可移动至连接端72的上方以对连接端72及与连接端72连接的元器件的导电件进行保护，降低元器件的导电件裸露的概率，提高电池2的安全性能。
本申请第三方面的实施例提供了一种用电设备，用电设备包括上述实施例中的电池2，电池2用于向用电设备提供电能。
本申请实施例的技术方案中提出的一种用电设备中，由于用电设备包括上述电池2，故用电设备具有上述电池2的所有优点。用电设备可以是上述任一应用该电池2的设备或系统。
