背景技术
电动车发展初级阶段往往采用通用工业级电容产品以满足电性能的要求，除了电性能，电动汽车对零部件的电气性能及振动性能有着较高的要求。工业级产品的设计没有考虑到振动对产品的影响。而目前市场上设计的电动车电容一个电容有两对端子引出，一对用于IGBT的引出，一对用于直流母线的连接，造成电容内部电极设计复杂，成本高。
发明内容
本发明旨在至少在一定程度上解决现有技术中的上述技术问题之一。为此，本发明第一方面的目的在于提出一种电动汽车的电容器，该电容器中的电容器芯子组采用一对电极连接所述电动汽车的直流母线和绝缘栅双极型基体管。

根据本发明的电动汽车的电容器，具有多个电容器芯子组，且每个电容器芯子组采用一对电极引出，该电极对分别与直流母线和绝缘栅双极型晶体管相连。由此，多个电容器芯子组相互独立地集成在一个电容器内，使电容器安装方便，同时保证了电容器的振动可靠性，每个电容器芯子组通过一对电极既电连接电动汽车的直流母线又电连接绝缘栅双极型晶体管，从而使电容器的内部结构简单，且减少了电容器的电极数量，降低了电容器的成本。
另外，根据本发明上述的电动汽车的电容器，还可以具有如下附加的技术特征：

每个所述卡线槽均包括相互垂直的第一卡线槽部和第二卡线槽部，且所述第一卡线槽部和所述第二卡线槽部间隔开设置。由此，提高了空间利用率。避免将导线全部容纳在卡线槽内，即使导线因加工误差导致连接电极和直流母线的导线长度与卡线槽的延伸长度不一致，也可以快速地被卡线槽卡持，避免导线松动，而且，间隔设置可以提高将导线卡持在卡线槽内的效率。
所述壳体的底壁上设有相互平行的第一凸棱和第二凸棱，且所述第一凸棱和所述第二凸棱间隔形成一个所述第一卡线槽部。由此，使壳体的结构简单，且避免在壳体上开槽造成壳体的局部位置厚度薄的问题，提高了壳体的结构强度。
所述第一凸棱的内壁面上设有第一卡凸，所述第二凸棱上设有与所述第一卡凸相对的第一缺口。可以便于将导线卡入第一卡线槽部内，从而提高第一卡线槽部的卡线效率。
所述壳体的底壁上设有多个第三凸棱，多个所述第三凸棱间隔设置形成多个所述第二卡线槽部。由此，壳体的结构简单，且便于形成第二卡线槽部。
形成所述第二卡线槽部的两个所述第三凸棱中的一个的内侧壁面上设有第二卡凸，且形成所述第二卡线槽部的两个所述第三凸棱中的另一个在于所述第二卡凸对应处形成第二缺口。由此，通过第二卡凸可以将导线稳定的卡持在第二卡线槽部内，而且，与第二卡凸相对的第二缺口可以便于将导线卡入第二卡线槽部内，从而提高第二卡线槽部的卡线效率。
根据本发明第二方面的电动汽车，包括：绝缘栅双极型晶体管、直流母线和电容器。所述电容器为根据本发明前述的电动汽车的电容器，所述电容器的接线端子组中的一对电极与所述绝缘栅双极型晶体管和所述直流母线均电相连。
根据本发明的电动汽车，连接直流母线和绝缘栅双极型晶体管的电容器采用了根据本发明第一方面的电动汽车的电容器。由此，多个电容器芯子组相互独立地集成在一个电容器内，使电容器安装方便，同时保证了电容器的振动可靠性，每个电容器芯子组通过一对电极既电连接电动汽车的直流母线，又电连接绝缘栅双极型晶体管，从而使电容器的内部结构简单，且减少了电容器上电极数量，降低了电动汽车的成本。
所述电极直接连接到所述绝缘栅双极型晶体管上，且所述电极通过导线连接所述直流母线。由此，使电容器的安装方便，提高了电容器的安装效率。

具体实施方式
下面详细描述本发明的实施例，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，旨在用于解释本发明，而不能理解为对本发明的限制。

电动车发展初级阶段往往采用通用工业级电容产品以满足电性能的要求，除了电性能，电动汽车对零部件的电气性能及振动性能有着较高的要求。工业级产品的设计没有考虑到振动对产品的影响。而目前市场上设计的电动车电容一个电容有两对端子引出，一对用于IGBT的引出，一对用于直流母线的连接，造成电容内部电极设计复杂，且由于电极数量较多造成成本高。为此，本发明提出了一种每个电容器芯子组均仅采用一对电极连接直流母线和绝缘栅双极型晶体管的电动汽车的电容器，该电容器专用于连接电动汽车的直流母线和绝缘栅双极型晶体管。
下面参照附图详细描述本发明实施例的电动汽车的电容器100。
如图1和图2所示，根据本发明实施例的电动汽车的电容器100，包括：壳体1、电容器芯子组(未示出)和接线端子组2。
具体而言，所述电容器芯子组为多个，多个所述电容器芯子组相互独立地设置在壳体1内，每个电容器芯子组均相当于一个独立工作的电容，每个电容器芯子组均包括一个或多个电容器芯子(未示出)。其中，多个电容器芯子组相互独立的设置是指，多个电容器芯子组之间没有连接关系，多个电容器芯子组相互独立的运行。接线端子组2为多个，多个接线端子组2设在壳体1上，多个接线端子组2与多个所述电容器芯子组一一对应地相连，且每个接线端子组2均包括伸出壳体1的一对电极21(即两个电极21)。其中，接线端子组2的一对电极用于既与电动汽车的直流母线电连接，又与电动汽车的绝缘栅双极型晶体管200(即IGBT)电连接。
根据本发明实施例的电动汽车的电容器100，具有多个电容器芯子组，且每个电容器芯子组采用一对电极21引出，该电极对与直流母线和绝缘栅双极型晶体管200相连。由此，多个电容器芯子组相互独立地集成在一个电容器内，使电容器安装方便，同时保证了电容 器的振动可靠性，每个电容器芯子组通过一对电极21既电连接电动汽车的直流母线，又电连接绝缘栅双极型晶体管，从而使电容器100的内部结构简单，且减少了电容器100的电极21数量，降低了电容器100的成本。
该电容器100通过一对电极21连接电动汽车的直流母线和绝缘栅双极型晶体管，其中电极21直接连接到绝缘栅双极型晶体管200上，且通过导线连接电极21与电动汽车的直流母线。
此外，一个接线端子组2的一对电极21均连接绝缘栅双极型晶体管，同时此接线端子组2的一对电极21也均与直流母线相连。
进一步地，每个接线端子组2均同时连接绝缘栅双极型晶体管和直流母线。
如图1所示，在本发明的一些实施例中，电极21通过导线300连接直流母线(未示出)，参照图1至图5，多个电极21间隔设置在壳体1的一个侧壁(即如图1所示壳体1的前侧壁)上，且壳体1的底壁上设有与多个电极21对应的卡线槽101，连接所述直流母线和电极21的导线300被卡线槽101卡持，以避免导线300松动或摇晃导致所述直流母线和电极21连接不稳定。由此，在电容器100上设有卡线槽101，可以使电容器100连接电动车直流母线的导线300卡持在卡线槽101内，使连接电容器100时，导线有序不搭接，从而便于该电容器100的连线，提高了电容器100连线的安全性。
本领域普通技术人员可以理解的是，也可以不设置卡线槽101，不采用卡持装置卡持连接电极21和直流母线的导线300，或者采用其它形式的卡持结构卡持导线300。
进一步地，如图1所示，卡线槽101为多个，多个卡线槽101与多个电极21一一对应，多个卡线槽101的入口端1011与壳体1设有电极21的侧壁(即如图1中壳体1的前侧壁)平齐，以便于卡持在卡线槽101内的导线300连接电极21。多个卡线槽101的出口端1012与壳体1的另一个侧壁(即如图1中壳体1的左侧壁)平齐，以便于卡持在卡线槽101内的导线引出。由此，便于导线300连接电极21以及与电动汽车的直流母线连接，从而便于该电容器100的连线和安装，提高了安装电容器100的效率。
有利地，如图1所示，每个卡线槽101均包括相互垂直的第一卡线槽部102和第二卡线槽部103。在该电容器100的安装过程中，电极21直接连接到绝缘栅双极型晶体管上，而连接直流母线的导线一端与电极21连接另一端从电容器100的侧面引出，从而避免了连接电动汽车的直流母线从与设有电极21的侧壁相对的一个侧壁引出而导致导线占用空间大的问题，提高了空间利用率。
换言之，如果将卡线槽101设置成直线形状，使卡线槽101的入口端1011与壳体1的前侧壁平齐，而使卡线槽101的出口端1012延伸至壳体1的后侧壁，卡持在卡线槽101内的导线的一端可以方便地与电极21相连，而卡持在卡线槽101内的导线的另一端从壳体1 的上侧壁引出，由于电极21与绝缘栅双极型晶体管200采用直接连接的方式连接，从壳体1的后侧壁引出的导线将占用较大的空间，且不便于导线连接直流母线。
进一步地，如图1所示，第一卡线槽部102和第二卡线槽部103间隔开设置。由此，避免将导线全部容纳在卡线槽101内，即使导线300因加工误差导致导线300长度与卡线槽101的延伸长度不一致，也可以使导线300快速地被卡线槽101卡持，以及避免导线300松动，而且，间隔设置可以提高将导线300卡持在卡线槽101内的效率。
采用间隔设置的第一卡线槽部102和第二卡线槽部103可以在导线300过长和过短时，都可以使导线300稳定的卡持在卡线槽101内，而且，在将导线300卡持在卡线槽101内时，只需要将导线300的一个端部卡持在第一卡线槽部102内，而将导线300的另一个端部卡持在第二卡线槽部103内即可使导线300被稳定的卡持。从而便于卡线槽101卡持导线300，提高了导线300的安装效率。
有利地，如图1所示，壳体1的底壁上设有相互平行的第一凸棱11和第二凸棱12，且第一凸棱11和第二凸棱12间隔形成一个第一卡线槽部102。由此，使壳体1的结构简单，且避免在壳体1上开槽造成壳体1的局部位置厚度薄的问题，提高了壳体1的结构强度。
当然，也可以在壳体1的底壁上直接开槽形成所述第一卡线槽部102。
进一步地，如图1所示，相邻的连个第一卡线槽部102的外侧壁上连接有加强筋14，以便于提高壳体1的结构强度，以及提高第一卡线槽部102卡线的稳定性。
有利地，第一凸棱11的内壁面上设有第一卡凸111，第二凸棱12上设有与第一卡凸111相对的第一缺口121。由此，通过第一卡凸111可以将导线300稳定的卡持在第一卡线槽102内，而且，与第一卡凸111相对的第一缺口121可以便于将导线300卡入第一卡线槽部102内，从而提高第一卡线槽部102的卡线效率。
此外，可以将第一凸棱11和第二凸棱12中的至少一个设置成自由端向内倾斜的形状，从而形成一个开口小，内部空间大的结构，也可以稳定的卡持导线300。
如图1和图2所示，在本发明的一些示例中，壳体1的底壁上设有多个第三凸棱13，多个第三凸棱13间隔设置形成多个第二卡线槽部103。由此，壳体1的结构简单，且便于形成第二卡线槽部103。
当然，也可以将第二卡线槽部103设置成与第一卡线槽部102类似的结构，例如，采用每个第二卡线槽部103均由两个凸棱间隔形成，且多个第二卡线槽部103的凸棱不共用。采用这种方式形成多个第二卡线槽部103，容易造成壳体1的结构复杂，不便于壳体1的成型。
进一步地，如图1所示，形成第二卡线槽部103的两个相邻的第三凸棱13中的一个的内侧壁面上设有第二卡凸131，且形成第二卡线槽部103的两个相邻的第三凸棱13中的另 一个在与第二卡凸131相对处形成有第二缺口132。由此，通过第二卡凸131可以将导线300稳定的卡持在第二卡线槽部103内，而且，与第二卡凸131相对的第二缺口132可以便于将导线300卡入第二卡线槽部103内，从而提高第二卡线槽部103的卡线效率。
此外，可以将多个第三凸棱13配合形成开口小内部空间大的结构，也可以稳定的卡持导线300。
有利地，壳体1一体形成。由此，提高了壳体1的结构强度，且便于壳体1的成型，提高了壳体1的成型效率且降低了壳体1的成型成本。
下面参照附图描述本发明的一个具体实施例的电动汽车的电容器100。
如图1和图2所示，壳体1内形成有用于容纳多个电容器芯子组的容纳腔104，其中，电容器芯子组为两个，两个电容器芯子组与壳体1之间通过绝缘灌封材料间隔封装，每个电容器芯子组均由一个或多个电容器芯子组成，一个所述电容器芯子组通过从它两端的喷金层引出的导电片分别与一对电极21(即两个电极)实现电连接，且这两个电容器芯子组相互独立。其中，电容器芯子和电容器芯子组可以采用现有技术中的电容器芯子和电容器芯子组，因此，无需对电容器芯子和电容器芯子组进行详细描述，本领域的普通技术人员可以理解电容器芯子和电容器芯子组的具体结构以及它们的组成和工作原理。
本发明的电容器100可以分别与电动汽车的直流母线(或电源线)和绝缘栅双极型晶体管连接，其中，电容器100的电极21直接连接到绝缘栅双极型晶体管上，而直流母线可以通过导线300与电极21相连，其中连接电极21的导线300可以设置压线端子，从而可以使导线300可以方便且稳定的与电极21连接在一起。为了使导线300可以稳定地连接电极21，以及使导线300有序不搭接，本发明在电容器100的壳体1上设置了卡线槽101，从而可以将导线300卡持在卡线槽101内，使导线300稳定且有序。
具体而言，参照图1，壳体1上设有了四个卡线槽101，分别与四个电极21相对，其中，每个卡线槽101均包括第一卡线槽部102和第二卡线槽部103，第一卡线槽部102由相互平行的第一凸棱11和第二凸棱12间隔形成，且第一凸棱11的内壁面上设有第一卡凸111，第二凸棱12上设有与第一卡凸111相对的第一缺口121。壳体1上的相互平行的五个第三凸棱13间隔形成四个第二卡线槽部103，其中，五个第三凸棱13中位于最外侧的两个第三凸棱13的内侧面上设有第二卡凸131，且位于最中间的一个第三凸棱13的两个表面上均形成有第二卡凸131，另外两个第三凸棱13上形成有与第二卡凸131相对的第二缺口132。
本发明将两个相互独立的电容器芯子组合为一体，安装方便，同时保证电动车的振动可靠性；每个电容器芯子组一对电极引出，内部设计简单，节约制造成本。
根据本发明实施例的电动汽车的电容器100，实现了电容器同时与多组电容器芯子组及直流母线的连接，且互不干涉。而且还实现了一对电极可以同时连接IGBT和直流母线。电 容器与IGBT连接通过接插方式，与直流母线连接通过导线300，其中导线300带压线端子，连接到电容器100的电极21。导线300接入电极后，可卡持在外壳上的卡线槽101内，有序排布不搭接，以保证高压安全。
本发明采用一对电极21实现电容器100同时连接直流母线和绝缘栅双极型晶体管的功能，使线有序不搭接，保证高压安全。节省电容制造成本。
本发明的电容器可以为薄膜电容器。
根据本发明实施例的电动汽车的电容器，当电极21与IGBT和直流母线连接时，电容器与IGBT连接通过接插方式，与直流母线连接通过导线300连接，其中导线300上设有压线端子，导线300通过压线端子与电容器的电极相连，实现了一对电极可以同时连接IGBT和直流母线，通过导线300与直流母线连接，减少从电容内部多引出一对连接直流母线的电极，节约成本。直流母线通过带压线端子的导线300与电极连接，导线300可卡持在外壳上的卡线槽101内，有序排布不搭接，以保证高压安全。两组独立电容，于同一壳体中，外壳固定端采用镂空设计，大大增强产品的抗振性能。
根据本发明第二方面实施例的电动汽车，包括：电容器100、绝缘栅双极型晶体管200和直流母线(未示出)。
具体而言，电容器100为根据本发明第一方面实施例所述的电动汽车的电容器，电容器100的接线端子组2分别与绝缘栅双极型晶体管200和所述直流母线相连。
根据本发明实施例的电动汽车，连接直流母线和绝缘栅双极型晶体管200的电容器100采用了根据本发明第一方面实施例的电动汽车的电容器。由此，多个电容器芯子组相互独立地集成在一个电容器内，使电容器安装方便，同时保证了电容器的振动可靠性，每个电容器芯子组通过一对电极21既电连接电动汽车的直流母线，又电连接绝缘栅双极型晶体管，从而使电容器100的内部结构简单，且减少了电容器100上电极21数量，降低了电动汽车的成本。
在本发明的一个实施例中，电极21直接连接到绝缘栅双极型晶体管200上，且电极21通过导线300连接所述直流母线。由此，使电容器100的安装方便，提高了电容器的安装效率。
具体而言，绝缘栅双极型晶体管200上设有连接片，且该连接片上形成有第一螺钉连接孔，电极21上具有第二螺钉连接孔，将电极21叠放在连接片上，并使第一螺钉连接孔与第二螺钉连接孔对齐，最后通过螺钉将电极21和连接片连接到一起。
本领域普通技术人员可以理解的是，电极21与绝缘栅双极型晶体管200也可以采用其它的连接方式。
导线300的端部设有压线端子，且导线300通过所述压线端子与电极21相连。由此， 可以使导线300与电极21连接稳定，从而提高电动汽车的稳定性和安全性。
