技术领域
本申请涉及电池技术领域，特别是涉及一种电池采样组件及电池箱。
背景技术
随着新能源技术不断发展，电池箱的应用越来越广泛，常用于混合动力汽车或电动汽车。因此，电池箱的安全性及可靠性尤为重要。
为了确保电池箱的安全运行，需要对电池箱内各单体电池的电压、温度等信息进行采集，以监测各单体电池的运行情况，进而保证电池箱的安全运行。由于柔性电路板具有柔性且体积小，可以为电池箱节省一定内部空间且成本低，因此被广泛用于电池箱中对单体电池的电压、温度等信息进行采集。
用于采集信息的柔性电路板需要与电池采样控制单元连接，即CSC，通过CSC将采集的信息最终传输至电池管理系统。然而，现有技术中的柔性电路板在应用至电池箱中进行采样时，存在如下问题，柔性电路板在连接至单体电池带电后，柔性电路板用于与CSC连接的接头处的插针容易进入金属碎屑而造成短路，影响电池箱的采样安全。
因此，亟需一种新的电池采样组件及电池箱。
发明内容

一方面，根据本申请实施例提出了一种电池采样组件，包括：柔性电路板及设置于柔性电路板的连接器，柔性电路板能够与待测单体电池电连接，连接器包括基座及设置于基座并相互电连接的第一接头及第二接头，连接器通过第一接头与柔性电路板电连接，第二接头用于与外界器件电连接；其中，第二接头包括多个间隔设置且位于基座内的插针以及设置于基座并与插针一一对应的插孔，插针延伸至与其对应的插孔。
另一个方面，根据本申请实施例提供一种电池箱，包括：电池箱体；电池模组，设置于电池箱体，电池模组包括多个层叠设置的单体电池、将多个单体电池串联和/或并联的连接片以及相互间隔并夹持多个单体电池设置的两个端板；电池采样控制单元，连接于其中一个端板；及上述的电池采样组件，柔性电路板设置于电池模组并与连接片电连接，第二接头与电池采样控制单元电连接。
根据本申请实施例提供的电池采样组件及电池箱，电池采样组件包括柔性电路板及设置于柔性电路板的连接器，连接器包括基座及设置于基座并相互电连接的第一接头及第二接头，第一接头与柔性电路板电连接。使用时，可以通过柔性电路板与待检测的单体电池电连接，以采集单体电池的信息，通过第二接头与电池采样控制单元等外界器件电连接，以将采集的单体电池的信息最终传输至电池管理系统。由于第二接头包括多个间隔设置且位于基座内的插针以及设置于基座并与插针一一对应的插孔，插针延伸至相应的插孔，使得第一接头在与单体电池连接带电后，连接器既能够通过插孔保证与外界器件的连接，同时由于基座的防护，能够有效的避免第二接头的多个插针之间进入金属碎屑而造成短路，保证电池箱的采样安全。

本申请实施例提供的电池采样组件，能够用于采集电池箱内各单体电池的电压及温度等信息。且在连接至单体电池并带电后，能够避免出现短路现象，能够保证电池系统的采样安全。
为了更好地理解本申请，下面结合图1至图8根据本申请实施例的电池采样组件及电池箱进行详细描述。
请参阅图1，图1示出了本申请实施例的电池采样组件的分解示意图。本申请实施例提出了一种电池采样组件1，包括柔性电路板10及设置于柔性电路板10的连接器20。柔性电路板10具体可以采用蚀刻线路的形式起到传导电压、温度及供电作用。柔性电路板10能够与待测单体电池电连接，具体可以与串联和/或并联各待测单体电池的连接片键合。
请一并参阅图2至图5，图2示出了图1中A处放大图，图3示出了本申请实施例的连接器20的轴测图，图4示出了图3所示结构的仰视图，图5示出了本申请实施例的连接器20的局部剖视图。如图2至图5所示，连接器20包括基座21及设置于基座21并相互电连接的第一接头22及第二接头23。连接器20通过第一接头22与柔性电路板10电连接，以获取并传输柔性电路板10所采集的各单体电池的电压及温度等信息。本实施例中，第一接头22优选包括多个间隔设置且安装于基座21的连接针221，各连接针221的局部沿其各自的长度方向延伸出基座21预定距离，所说的预定距离不做具体尺寸限定，可以根据实际需要设定，同时，第一接头22并不限于上述结构，只要能够保证便于与柔性电路板10电连接，以获取所采集的单体电池信息均可。
连接器20的第二接头23包括多个间隔设置且位于基座21内的插针 231以及设置于基座21并与插针231一一对应的插孔232，插针231延伸至与其对应的插孔232。第二接头23用于与电池采样控制单元等外界器件电连接，以将采集的单体电池的信息最终传输至电池管理系统。第二接头23采用上述结构，使得第一接头22在与单体电池连接带电后，由于基座21的防护，能够有效的避免第二接头23的多个插针231之间进入金属碎屑而造成短路，保证电池箱的采样安全。同时，相应设置于基座21内并与插针231一一对应的插孔232能够满足与电池采样控制单元等外界器件的电连接要求。电池采样控制单元的连接端子穿入插孔232即可与第二接头23相应的插针231电连接，以获取单体电池的电压及温度等信息。
作为一种可选的实施方式，由于第二接头23的各个插针231的直径较小，在应用至电池箱，获取并传输信息时比较容易歪斜，而相邻的两插针231之间的距离较小，一旦相邻的插针231因歪斜而搭接到一起时，很容易引起短路，进而给电池箱的采样造成不必要的损失。因此，作为一种可选的实施方式，插孔232的孔壁沿与其相对应的插针231的延伸方向延伸形成限位部26，使得插针231与外界器件连接的一端被限制于相应的限位部26内。即使在与外界器件连接时，也能够有效的避免插针231歪斜，进而能够更好的保证电池采样组件1的安全性能。
由于第二接头23在与电池采样控制单元等外界器件连接时，需要将基座21的局部插接进入相应的设备中，以使得第二接头23与相应的设备电气连接。由此，作为一种可选的实施方式，在基座21上设置有沿插针231的延伸方向延伸的导向部24以及位于导向部24端面的定位部25，通过设置导向部24能够给基座21提供相应的导向，进而准确快捷的与相应的设备电连接。
本实施例中，导向部24的结构可以为沿着插针231的延伸方向延伸的导向条，导向条可以与基座21一体成型。同时，相应设置的定位部25能够限制基座21插接进入设备中的深度，能够避免第二接头23与设备之间接触不良，保证二者的可靠的电连接。同时，也能够避免二者之间的过插接现象的发生，避免第二接头23的插针231因过插接而损伤。定位部25可以为凸出于基座21表面的凸块结构，可以与基座21一体成型，当 然，只要能够起到限位作用的其他结构均可。
请继续参阅图1，作为一种可选的实施方式，电池采样组件1进一步包括绝缘片30，绝缘片30连接于柔性电路板10厚度方向的下表面12且与柔性电路板10层叠设置，绝缘片30与柔性电路板10可以采用胶接形式连接。绝缘片30的形状及尺寸优选与柔性电路板10的形状及尺寸相同。
由于柔性电路板10一般设置于单体电池的顶盖上，以采集单体电池相应的电压及温度等信息，因此，柔性电路板10与单体电池之间保持绝缘是必要的。而相应设置的绝缘片30能够起到良好的绝缘作用，在电池采样组件1应用至电池箱时，可以将绝缘片30设置于单体电池与柔性电路板10之间，以满足柔性电路板10与单体电池之间的绝缘要求，进而保证电池箱的采样安全。同时，相应设置的绝缘片30还能够对柔性电路板10起到提高强度的作用，使得柔性电路板10不易被撕裂。
绝缘片30材质优选采用PC、PET等材料制成，当然，也可以采用满足绝缘要求的其他材料制成。绝缘片30的厚度为0.05mm～0.3mm之间的任意数值，包括0.05mm及0.3mm两个端值。更为优选的，本申请实施例的绝缘片30的厚度为0.175mm，在满足绝缘要求的基础上，能够有效的降低绝缘片30所占用的空间，同时能够尽量缩短键合线的长度。
由于电池采样组件1在应用至电池箱中，与单体电池及电池采样控制单元等设备连接时，柔性电路板10在其厚度方向大多需要进行折弯处理，以越过诸如端板等构件后并与电池采样控制单元等设备连接。为了避免柔性电路板10在被折弯处理时弯折角成死角而导致柔性电路板10在弯折处断裂，作为一种可选的实施方式，电池采样组件1进一步包括柔性垫40，柔性垫40连接于柔性电路板10厚度方向的上表面11且与柔性电路板10层叠设置。柔性垫40在长度方向的尺寸优选小于柔性电路板10在长度方向的尺寸。柔性垫40优选位于柔性电路板10与连接器20相连接的一侧。通过设置柔性垫40，能够在柔性电路板10被折弯时起到缓冲的作用。
柔性垫40与柔性电路板10之间可以采用胶接的形式连接，柔性垫40具体可以采用泡棉、橡胶等材料制成，当然，也可以采用满足缓冲要求的 其他材料制成。柔性垫40的厚度优选为2mm～10mm之间的任意数值，包括2mm及10mm两个端值。更为优选的，本申请实施例的柔性垫40的厚度为2mm，在满足缓冲要求的基础上，能够有效的降低柔性垫40所占用的空间，且满足柔性电路板10的弯折要求。
作为一种可选的实施方式，柔性垫40背离柔性电路板10的表面设置有粘胶层41，所说的粘胶层41优选为双面胶，使得柔性垫40不仅能够在柔性电路板10弯折时起到缓冲的作用，同时能够对弯折后的柔性电路板10起到弯折定型的作用。
请继续参阅图1、图2，为了保证柔性电路板10与连接器20的第一接头22能够可靠的电连接，作为一种可选的实施方式，电池采样组件1还包括加强件50，加强件50为框架结构且连接于基座21，柔性电路板10靠近基座21的端部夹持于加强件50与基座21之间。具体实施时，加强件50面向基座21的表面与基座21可以采用胶粘的形式连接。通过设置加强件50并使得加强件50采用框架结构，能够使得柔性电路板10靠近基座21的端部与基座21的相对位置固定，进而保证柔性电路板10与连接器20的第一接头22可靠的电连接，同时加强件50还能够对第一接头22的各连接针221起到保护作用。
请一并参阅图6、图7及图8，图6示出了本申请实施例的电池箱的结构示意图，图7示出了图6所示电池箱的局部结构示意图，图8示出了图7中B处放大图。
本申请实施例还提供一种电池箱，电池箱包括电池箱体5、电池模组2、电池采样控制单元4及上述任意实施例的电池采样组件1。电池模组2设置于电池箱体5，电池模组2包括多个层叠设置的单体电池201，将多个单体电池201串联和/或并联的连接片202以及相互间隔并夹持多个单体电池201设置的两个端板3，电池采样控制单元4连接于其中一个端板3。本实施例中，电池采样组件1的数量为三组，各电池采样组件1的柔性电路板10设置于电池模组2并与相应的连接片202电连接，各电池采样组件1的第二接头23分别与电池采样控制单元4电气连接，优选的，可以利用电池采样控制单元4的多面板特征，配合柔性电路板10的引脚定义 进行跳线处理，更便于使得连接器20的引脚定义与电池采样控制单元4的引脚定义相匹配。
可以理解的是，电池采样组件1并不限于为三组，具体数量可以根据所需采集的单体电池201的数量及排布设定，只要能够满足单体电池201的信息采集均可。当电池采样组件1具有柔性垫40时，可以将其连同柔性电路板10折弯以越过端板3，同时通过柔性垫40上的粘胶层41将柔性电路板10及柔性垫40与端板3粘接固定。
本申请实施例提供的电池箱，能够通过电池采样组件1采集其内部的各单体电池201的电压及温度等参数信息，并将参数信息通过连接器20传输至电池采样控制单元4，通过电池采样控制单元4能够将参数信息最终传输至电池管理系统，实现对单体电池201的监测。
由于电池箱包括上述各实施例的电池采样组件1，在满足对单体电池201信息采集要求的同时，能够有效的避免连接器20短路现象的发生，保证电池箱的采样安全，使得电池箱能够安全稳定的运行。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
