Description

机动车辆的牵引电池的导电体和信号导体的保持设备
技术领域
本发明涉及一种用于机动车辆的牵引电池的导电体和信号导体的保持设备。
背景技术
在电动车辆以及混合动力车辆中安装有牵引电池。此类牵引电池具有多个彼此电互连的电池模块。每个电池模块具有多个彼此电互连的电池单元。一方面导电体和另一方面信号导体用于使牵引电池的电池模块互连。导电体优选被实施为汇流排并且用于从牵引电池开始朝向该机动车辆的电动机器的方向传输电能。此外，在该电动机器以发电机的方式运行时，这些汇流排用于从电动机器开始朝向牵引电池的方向传输电能。信号导体用于传输通信信号，以便尤其提供关于这些电池模块的电压信息和温度信息以用于控制目的和调节目的。
由这些导电体传输的电流可能导致非期望的电气效应或电磁效应，这些电气效应或电磁效应影响藉由这些信号导体进行的通信信号的传输。因此，在从实践中已知的机动车辆中，以距导电体间距较大的方式来铺设信号导体。
然而，导电体与信号导体在空间上的分隔无法在机动车辆的所有区域中以足够的规模实现。于是在这种情况下，经屏蔽的信号导体有所帮助。
然而，信号导体的屏蔽必须被接地。为此，相应信号导体的屏蔽必须接触到接地电位。这是高耗费且容易出错的。
发明内容
因此，存在对用于机动车辆的牵引电池的导电体和信号导体的保持设备的需求，即使在导电体与至少一个信号导体之间的间距较小的情况下，该保持设备也以简单的方式提供这些导电体与相应的信号导体之间的良好屏蔽。因此，本发明的目的在于，提供一种这样的保持设备。
该目的通过具有如下特征的用于机动车辆的牵引电池的导电体和信号导体的保持设备来实现：该保持设备具有：板形的基体，该板形的基体具有纵向侧和横向侧以及在这些纵向侧与横向侧之间延伸的顶侧和底侧；用于引导并且固定该牵引电池的导电体的元件，这些元件被布置在顶侧和底侧中的一侧；用于引导并且固定该牵引电池的至少一个信号导体的元件，这些元件被布置在顶侧和底侧中的另一侧，其中该板形的基体提供该信号导体或每个信号导体相对于这些导电体的EMV屏蔽，其中该板形的基体在相对的纵向侧和/或在相对的横向侧具有用于将该保持设备紧固在该机动车辆的框架上并使其接地的区段。
该保持设备具有板形的基体，该板形的基体具有纵向侧和横向侧以及在这些纵向侧与横向侧之间延伸的顶侧和底侧。
在顶侧和底侧中的一侧布置有用于引导并且固定牵引电池的导电体的元件。
在顶侧和底侧中的另一侧布置有用于引导并且固定该牵引电池的至少一个信号导体的元件。
该板形的基体提供该信号导体或每个信号导体相对于这些导电体的EMV屏蔽。
该板形的基体在相对的纵向侧和/或在相对的横向侧具有用于将该保持设备紧固在该机动车辆的框架上并使其接地的区段。
根据本发明的保持设备允许这些电导体相对于该信号导体或每个信号导体的有效屏蔽，尤其即使当相应的信号导体以距导电体相对较小的间距延伸时也是如此。可以省去经屏蔽的信号导体。无需使经屏蔽的信号导体的屏蔽接地。
根据一个有利的改进方案，用于引导并且固定这些导电体的这些元件沿该板形的基体的相对的纵向侧定位。用于将该保持设备紧固在该机动车辆的框架上并使其接地的这些区段优选沿该板形的基体的相对的横向侧定位。用于引导并且固定该信号导体或每个信号导体的这些元件平行于该板形的基体的纵向侧延伸。根据本发明的保持设备的这种设计方案是特别优选的，以便良好地引导一方面这些导电体以及另一方面这些相应的信号导体，并且另一方面以简单的方式提供相应的信号导体相对于这些导电体的可靠的屏蔽。
附图说明
本发明的优选改进方案自从属权利要求和以下的说明中得出。本发明的实施例将借助附图进行详细说明，但并不局限于此。在附图中：
图1在根据本发明的用于机动车辆的牵引电池的导电体和信号导体的保持设备的区域中示出机动车辆的局部的透视图；
图2示出穿过图1的横截面；
图3示出图2的细节。
具体实施方式
图1在牵引电池的区域中示出被设计为电动车辆或混合动力车辆的机动车辆的车身结构的局部，其中由图1中的牵引电池示出了电池模块10。在此，电池模块10被定位在牵引电池的电池壳体中，其中该电池壳体优选是机动车辆的框架的组成部分。因此，图1示出支板11，这些支板为机动车辆的框架的以及因此电池壳体的组成部分，并且形成用于电池模块10的对应的容纳空间。在此，在机动车辆的前部区域以及机动车辆的后部区域中定位有多个电池模块10，其中在被定位在机动车辆的前部部分与被定位在机动车辆的后部部分中的电池模块10之间还布置有电池模块10，该电池模块可以与其他的电池模块10电互连并且在信号方面互连。每个电池模块10具有模块壳体10a和电池单元10b。
图1和图2示出导电体12，这些导电体用于尤其在电池模块10之间形成串联连接的情况下使电池模块10电互连。因此在图1中，第一导电体12以接口13连接到电池模块10的第一连接触点，另一个导电体12以接口13联接到电池模块10的第二连接触点。图1还示出第三导电体12，该第三导电体在电池模块10上延伸，其他两个导电体12以其接口13连接在该电池模块上。
图1、图2还示出信号导体14。这个信号导体14用于在这些电池模块10之间或在这些电池模块与控制装置之间传输数据信号或通信信号。
在图1和图2中所示的配置中，在电池模块10之上定位有根据本发明的保持设备15，该保持设备在图3中在横截面图中与导电体12和信号导体14一起以单独图示被示出。
保持设备15具有板形的基体，该板形的基体具有纵向侧16和横向侧17。在纵向侧16与纵向侧17之间延伸有板形的基体15的顶侧18以及底侧19。
在顶侧18和底侧19中的一侧(在所示的实施例中在顶侧18)布置有用于引导并且固定导电体12的元件20。
在此，这些元件20沿板形的基体的相对的纵向侧16定位，其中用于引导并且固定导电体19的这些元件20包括螺纹螺栓20a和螺母20b(这些螺母与螺纹螺栓20a共同作用)以及紧固区段20c。
相应的紧固区段20c区段式地环绕相应的导电体12。
螺纹螺栓20a延伸穿过相应导电体12的紧固区段20c，其中螺母20b将相应导电体12的相应紧固区段20c固定在相应的螺纹螺栓20a处。
在板形的基体的顶侧18和底侧19中的另一侧(在所示的实施例中在底侧19)布置有用于引导并且固定相应的信号导体14的元件，其中用于引导并且固定相应的信号导体14的这些元件平行于板形的基体15的纵向侧16延伸。因此，这些元件21一方面包括平行于基体15的纵向侧16延伸的一条引导通道21a，该引导通道用于引导相应的信号导体14；并且另一方面包括被布置在引导通道21a中的多个固定夹21b，这些固定夹将信号导体14保持在引导通道21a中。
在此，以沿引导通道21a的纵向方向分布的方式定位有多个这样的固定夹21b。
因此，导电体12平行于保持设备15的纵向侧16延伸，相应的信号导体14同样平行于纵向侧16延伸、然而相对于保持设备或板形的基体在顶侧18和底侧19中的另一侧更靠内地延伸。
除了用于引导并且固定导电体12的元件20、20a、20b和20c以及用于引导并且固定相应的信号导体14的元件21、21a、21b之外，保持设备15的板形的基体在相对的纵向侧16和/或在相对的横向侧17(在所示的实施例中在两个相对的横向侧17)具有用于将保持设备紧固在机动车辆的框架(即在机动车辆的在图1中所示的支板11)上并使其接地的区段22。因此，保持设备15在信号导体14从引导通道21a中显露出来的两侧或两端处是接地的。通过在两侧或两端进行紧固和接地，尤其提高了接地的功能安全。如果可能在一侧或在一端无意地松开用于对保持装置进行紧固和接地的相应区段22，则布置在另一端的区段22仍始终确保对保持设备的紧固和接地。
优选地，保持设备15的板形的基体实施成金属性的并且由此实施成导电的。导电体12也实施成金属性的并且由此实施成导电的。而导电体12的紧固区段20c是由不导电的材料实施而成的。
因此，本发明提出一种用于机动车辆的牵引电池的高电压导电体12和低电压信号导体14的保持设备15，该保持设备一方面用于引导并且固定优选形成为汇流排的导电体12、用于引导并且固定相应的信号导体14、并且用于使信号导体14相对于导电体12屏蔽，以便为相应的信号导体提供EMV屏蔽。根据本发明的保持设备15是结构简单的，并且允许对相应的信号导体14进行有效的屏蔽。
