具体实施方式
下面详细描述本申请的实施例，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，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述根据本申请实施例的电动总成1。
如图1-图19所示，根据本申请实施例的电动总成1包括箱体总成100、电机200、变速器400和冷却装置。
箱体总成100内设有安装板160，安装板160将箱体总成100内的空间分隔出沿电机轴210的轴向排列的电机容纳腔110和变速器容纳腔120。电机200设在电机容纳腔110内。变速器400设在变速器容纳腔120内，电机200与变速器400动力耦合连接。所述冷却装置设在电机容纳腔110内且对箱体总成100进行冷却。
根据本申请实施例的电动总成1，通过将电机200和变速器400设在箱体总成100内，相比相关技术中变速器的前箱体与电机的前端盖连接的电机总成，电机200和变速器400共用一个箱体总成100，实现电动总成1的一体化设计，不仅可以省去设置多个箱体总成100结构，而且可以省去连接电机总成和变速器总成所需的螺栓，便于简化电动总成1的结构，减少电动总成1的零件数量，提高电动总成1的集成度，提高电动总成1的生产效率。
并且，电机200和变速器400共用一个箱体总成100，相比相关技术中电机总成和变速器总成单独设置，可以节省空间，便于缩短电动总成1的轴向距离，使电动总成1的结构紧凑合理，提高电动总成1的空间利用率，便于电动总成1的设置。同时便于电动总成1的安装和维修，便于提高电动总成1的可靠性和稳定性。
此外，通过电机200和变速器400共用一个箱体总成100，可以减少电机200和变速器400集成使用的零部件，便于减轻电动总成1的重量，例如当电动总成1应用于车辆11 中，可以降低所述车辆11的整体重量，便于降低所述车辆11的成本，降低所述车辆11的能量损耗，提高所述车辆11的工作效率，提高所述车辆11的续航能力。
同时，通过设置箱体总成100箱体总成100内设有安装板160，装配过程仅需要进行一次装夹，便于电动总成1的装配成型，便于减小电动总成1的误差，便于电机200和变速器400的安装和设置，便于提高电机200和变速器400的同轴度和径向上安装的准确性，便于提高电动总成1的工作性能。
进一步地，通过在所述冷却装置设在电机容纳腔110内且对箱体总成100进行冷却，这样不仅可以利用所述冷却装置对电机200进行冷却，便于电机200的温度范围，避免电机200温度过高而影响电机200的正常工作，甚至造成电机200的损坏，保证电机200工作的可靠性和稳定性，而且所述冷却装置可以同时对箱体总成100进行冷却，一方面可以控制箱体总成100的温度范围，使箱体总成100合适的温度范围内稳定运行，而且可以通过箱体总成100进一步对箱体总成100内的变速器400进行冷却，从而便于提高电动总成1整体的散热性能，提高电动总成1的工作可靠性和稳定性。
由于所述冷却装置可以对箱体总成100进行冷却，相比相关技术中电动总成的冷却方式，所述冷却装置不但可以对电机200进行冷却，也可以对箱体总成100进行冷却，使电动总成1可以充分受到所述冷却装置的冷却，并且可以提高电动总成1各处的冷却均匀性，增强电动总成1的冷却效果，提高电动总成1的冷却可靠性。
因此，根据本申请实施例的电动总成1具有结构紧凑、冷却效果好等优点。
下面参考附图描述根据本申请具体实施例的电动总成1。
在本申请的一些具体实施例中，如图1-图19所示，根据本申请实施例的电动总成1包括箱体总成100、电机200、变速器400和冷却装置。
具体地，安装板160构造为箱体总成100的一部分，所述冷却装置通过安装板160对箱体总成100进行冷却。这样不仅便于安装板160的设置，而且可以通过安装板160传递热量，提高电动总成1的整体冷却效果，例如电机壳体140和变速器箱体101也可以受到冷却。例如，可以通过电机容纳腔110内的电机冷却液对安装板160进行冷却，箱体总成100通过安装板160传递热量，进一步使变速器400的壳体得到冷却，从而使变速器400壳体内的变速器400得到冷却。
根据本申请的一个实施例，安装板160构造为前箱体180的一部分，所述冷却装置通过安装板160对前箱体180进行冷却，使箱体总成100整体得到冷却，例如，电机容纳腔110内的电机冷却液可以同时对电机200和安装板160进行冷却，并通过安装板160传递热量。总之，通过电机容纳腔110内的电机冷却液可以同时对前箱体180和变速器400进行冷却。
根据本申请的另一个实施例，安装板160构造为电机壳体140的一部分，因为电机冷却液对电机壳体140进行冷却，这样也可以对安装板160进行冷却，并通过安装板160传递热量，使变速器箱体101也可以受到冷却，从而使箱体总成100得到冷却，提高电动总成1的整体冷却效果。总之，通过电机200内的电机冷却液也可以同时对电机壳体140和变速器400进行冷却。
根据本申请的一个实施例，所述冷却装置为液冷装置，电机容纳腔110内设有电机冷却液道，所述液冷装置通过所述电机冷却液道将冷却液输送至安装板160以及电机200。具体而言，所述液冷装置可以为水冷装置。这样可以利用液冷装置对电机200，并通过安装板160对电动总成1整体进行冷却，保证电动总成1可靠地散热，提高电动总成1的冷却效果，避免温度过高而影响电动总成1的正常工作。
具体地，变速器容纳腔120内设有变速器冷却液道，所述变速器冷却液道与所述电机冷却液道连通，所述变速器冷却液道将所述冷却液输送至变速器400。这样可以利用液冷装置同时对电机200和变速器400进行冷却，进一步提高电动总成1的整体进行冷却效果，提高电动总成1的散热性能，进一步提高电动总成1的冷却效果，保证电动总成1的工作可靠性和稳定性。
更为具体地，变速器400的壳体内可以设置冷却润滑液，变速器400的壳体套设在变速器400外周，便于对变速器400起到冷却散热效果，而安装板160设置在变速器400端部一侧，主要对变速器400端部进行冷却散热，两种冷却方式各有侧重，共同达到对变速器400充分冷却的效果。另一方面，通过电机200的电机冷却液冷却变速器400，同时变速器400的润滑冷却液冷却电机200，冷却方式各有侧重，通过两者的组合加强对电动总成1的冷却效果，共同达到对电动总成1充分冷却的效果。
根据本申请的另一个实施例，所述冷却装置为风机，所述风机设在电机容纳腔110内，所述风机对安装板160和电机200进行送风。这样可以利用所述风机对安装板160和电机200进行风冷散热，便于提高电动总成1的散热效果。
可选地，电机200与安装板160之间的距离小于预设距离。这里需要理解的是，所述预设距离为使安装板160对电机200进行冷却的最大距离，本领域的技术人员可以通过电动总成1的额定电压与额定电流得出。例如，电机200与安装板160之间的距离可以小于10毫米，优选为7.5毫米。由于预设值可以设置为一个较小的值，以使电机200和安装板160之间的距离很小，这样可以使得电机200和安装板160之间相互近距离冷却，在安装板160冷却后，电机200能快速得到冷却。
可选地，如图9和图10所示，安装板160朝向电机200和/或变速器400的一侧设有筋条。由于所述筋条使得箱体总成100的刚度增强，固有频率提高，可以避免电动总成1 发生共振，便于降低电动总成1的噪声。这样可以增加电机200内的电机冷却液或气流与安装板160的接触面积，使所述冷却装置对安装板160的冷却更加充分。
具体地，电机200转动过程中，应力通过轴承传递到箱体总成100，在箱体总成100上增加所述筋条，有利于增加箱体总成100的刚性和强度，避免箱体总成100与电机200的线圈接触，防止电机200的元器件发生损坏，进一步提高电机200的工作可靠性和稳定性。
进一步地，所述筋条将安装板160与电机200之间的空间分隔为多个空腔162。这样便于空腔162的形成，便于利用通过空腔162的空气对电机200进行冷却。
根据本申请的一个实施例，如图12所示，所述筋条包括沿电机200的周向延伸的环形筋条163。这样可以提高箱体总成100的刚性和强度，提高箱体总成100的结构稳定性，提高箱体总成100的散热能力和冷却效果。
根据本申请的另一个实施例，如图10所示，所述筋条包括沿电机200的径向延伸的条状筋条161，条状筋条161为多个且多个条状筋条161沿安装板160的周向间隔设置。这样可以使箱体总成100的受力更加均匀，进一步便于提高箱体总成100的刚性和强度，进一步便于提高电动总成1的降噪性能和散热性，提高电动总成1的冷却效果。
根据本申请的另一个实施例，所述筋条包括沿电机200的周向延伸的环形筋条163和沿电机200的径向延伸的条状筋条161，条状筋条161为多个且多个条状筋条161沿安装板160的周向间隔设置。这样可以同时提高箱体总成100沿电机200的周向和径向的刚性和强度，提高箱体总成100的结构可靠性，进一步提高箱体总成100的散热面积，提高电动总成1的散热冷却性能。
具体地，条状筋条161距离安装板160的高度由内至外逐渐减小。这样可以减小条状筋条161的设置空间，避免条状筋条161占用箱体总成100内过多的空间，进一步便于电机200和变速器400的安装和设置。另一方面，条状筋条161距离安装板160高度由内至外逐渐减小，中心最高，可以承受轴承对箱体总成100形成的高强度载荷。
根据本申请的一个实施例，箱体总成100包括变速器箱体101和电机箱体102，变速器箱体101包括前箱体180和后箱体190，电机箱体102包括电机壳体140和电机后端盖150，前箱体180和电机壳体140相邻设置，安装板160构造为前箱体180的一部分或者电机壳体140的一部分。这样便于电动总成1成为三段式结构，便于变速器容纳腔120和电机容纳腔110的形成，便于电动总成1的安装和拆卸。同时，安装板160是前箱体180的一部分或者电机壳体140的一部分，将安装板160集成在箱体总成100上，可以提高箱体总成100的结构更加合理紧凑，可以使安装板160受到变速器400润滑液的冷却作用，提高安装板160的润滑冷却效果。
进一步地，前箱体180和电机壳体140一体成型或者可拆卸连接。这样电动总成1可以为三段式结构，便于电机200和变速器400的设置。
根据本申请的另一个实施例，如图9和图10所示，箱体总成100包括变速器箱体101和电机箱体102，变速器箱体101包括前箱体180和后箱体190，电机箱体102包括电机前端盖170、电机壳体140和电机后端盖150，安装板160构造为前箱体180的一部分或者电机前端盖170的一部分。这样便于电动总成1成为三段式结构，便于变速器容纳腔120和电机容纳腔110的形成，便于电动总成1的安装和拆卸。同时，安装板160是前箱体180的一部分或者电机壳体140的一部分，将安装板160集成在箱体总成100上，可以提高箱体总成100的结构更加合理紧凑，可以使安装板160受到变速器400润滑液的冷却作用，提高安装板160的润滑冷却效果。
根据本申请的一个实施例，如图2所示，电机壳体140、电机前端盖170和前箱体180一体成型或者电机壳体140、电机前端盖170和前箱体180两者之间可拆卸连接。这样可以提高箱体总成的结构灵活性，便于优化箱体总成100的结构，便于减轻箱体总成100的重量，提高电动总成1的续航能力。
根据本申请的另一个实施例，电机前端盖170和前箱体180一体成型，且电机壳体140与电机前端盖170可拆卸地连接。这样便于简化箱体总成100的装配过程，提高箱体总成100的装配效率。
根据本申请的另一个实施例，电机前端盖170和电机壳体140一体成型，且电机前端盖170与前箱体180可拆卸地连接。这样便于变速器箱体101和电机箱体102的相互分离，便于提高箱体总成100的结构灵活性。
根据本申请的另一个实施例，电机壳体140和电机前端盖170通过螺栓连接，电机前端盖170和前箱体180通过螺栓连接，电机壳体140和电机后端盖150通过螺栓连接。这样便于电机壳体140、电机前端盖170、前箱体180和后箱体190的加工成型，便于简化成型工艺。电机壳体140前箱体180后箱体190电机后端盖150电机壳体140前箱体180后箱体190电机后端盖150电机壳体140前箱体180电机壳体140。由于电机前端盖170、电机壳体140和电机后端盖150均可拆卸，这样可以调节电机200的长度，例如电机壳体140可作为一个标准件单独调节长度，提高电机200的结构灵活性和应用范围。
具体地，如图9所示，前箱体180的外表面与电机壳体140的外表面之间连接有第一连接筋181、第二连接筋182和第三连接筋183中一个或多个，第一连接筋181连接在电机壳体140和前箱体180的上端面之间(上下方向如图9中的箭头A所示)，第二连接筋182连接在电机壳体140和前箱体180的下端面之间，第三连接筋183位于第一连接筋181与第二连接筋182之间。这样可以加强前箱体180和电机壳体140之间的连接强度，避免 前箱体180和电机壳体140的连接处出现强度薄弱点而造成变形或损坏，提高箱体总成100的整体结构性能。
可选地，如图3所示，变速器400包括主轴300，主轴300与电机200的电机轴210动力耦合连接，电机轴210和主轴300中的至少一个穿过轴过孔130与另一个相连，主轴300与电机200的电机轴210通过花键相连。这样便于电机轴210与主轴300直接传动，可以省去额外的传动结构，进一步简化电动总成1的结构，提高电动总成1的集成度，便于将电机200输出的动力及时传递到变速器400，便于提高电动总成1的传动效率，便于提高电动总成1动力传输的及时性和准确性。这样可以利用花键对主轴300和电机轴210进行固定和定位，避免主轴300和电机轴210之间发生相对转动，便于电动总成1的可靠传动，便于保证电动总成1的传动效率。这样不仅可以省去连接主轴300和电机轴210的其他结构，从而进一步简化电动总成1的结构，提高电动总成1的集成度，而且由于主轴300和电机轴210相互套接进一步缩短电动总成1的轴间距，进一步便于控制电动总成1在电机轴210轴向上的尺寸。
进一步地，如图2所示，主轴300上设有轴孔310，轴孔310的内周面设有内花键311，电机轴210的外周面设有外花键211，电机200的电机轴210配合在轴孔310内且内花键311与外花键211相互配合。这样便于内花键311的加工，有利于提高内花键311的加工精度，利用内花键311和外花键211相互配合，不仅可以实现主轴300和电机轴210的传动连接，而且可以实现主轴300和电机轴210的可靠定位，进一步防止主轴300和电机轴210之间发生相对转动。同时电机200为三段式电机，主轴300和电机轴210相互套接设置，电机200的长度可以根据需要进行调节，便于改变电机200的扭矩和功率，便于提高电机200的兼容性。
具体地，轴孔310沿主轴300的轴向贯通主轴300，轴孔310内配合有挡油板320，挡油板320、轴孔310的内周壁和电机轴210共同限定出储油腔330，储油腔330内填充有润滑油，挡油板320上设有通气孔350。这样便于润滑油的设置，能有效的防止轴孔310内润滑油的泄露，起到保护花键润滑系统的作用。这样可以使主轴300具有储油的功能，可以对花键进行润滑和冷却，通气孔350可以将产生的气体适时排出，设置沿主轴300的轴向贯通的轴孔310，可以避免轴孔310内存在气体而影响电机轴210和主轴300的安装。
更为具体地，挡油板320与轴孔310之间以及电机轴210的外周面与轴孔310的内周面之间配合有密封挡圈340。这样便于对储油腔330进行密封，可以避免储油腔330内的润滑油发生泄露，提高储油腔330的密封效果。
具体地，如图2所示，电动总成1还包括多个轴承，多个所述轴承分别套设在电机轴210和主轴300外且沿电机轴210和主轴300的轴向间隔设置。这样便于电机轴210和主 轴300顺畅地转动，便于提高电机轴210和主轴300转动的可靠性和准确性。
根据本申请的一个实施例，如图8所示，多个所述轴承包括第一轴承510、第二轴承520和第三轴承530，第一轴承510和第二轴承520分别邻近主轴300的两端设置，第三轴承530邻近电机轴210远离主轴300的一端设置。这样不仅便于电机轴210和主轴300的设置，进一步便于电机轴210和主轴300顺畅地转动，而且可以减少所述轴承的数量，降低电动总成1的成本。
具体地，第三轴承530设在电机轴210远离变速器400的一端与箱体总成100之间，第一轴承510设在主轴300远离电机200的一端与箱体总成100之间，第二轴承520设在电机200轴靠近主轴300的一端和主轴300靠近电机轴210的一端中的至少一个与箱体总成100之间。这样可以使电机轴210和主轴300的受力更加均衡，便于提高电动总成1的工作性能。
可选地，第二轴承520套设在主轴300外且位于主轴300与电机轴210在轴向上的重叠处。这样可以利用第二轴承520对主轴300和电机轴210进行支撑，保证主轴300和电机轴210的设置可靠性。由于主轴300与电机轴210在轴向上的重叠处是转动形成应力集中的地方，通过第二轴承520的有效支撑，可以防止主轴300与电机轴210发生断裂，提高主轴300与电机轴210的工作性能。
根据本申请的另一个实施例，如图7所示，电动总成1还包括第四轴承540，第四轴承540套设在电机轴210上且位于电机轴210与电机壳体之间。这样可以利用第四轴承540加强对电机轴210的支撑，进一步提高电机轴210的设置可靠性。
具体地，第四轴承540在电机轴210的轴向上位于主轴300和电机200的定子之间。这样可以使主轴300和电机200的受力更加均匀，便于提高主轴300和电机200之间动力传递的可靠性和稳定性。
可选地，如图11所示，电机壳体140的外表面设有沿电机壳体140的外表面布设的加强筋141。这样不仅便于提高电机壳体140的强度，而且可以增加电机壳体140的表面积，提高电机壳体140的散热性能。
具体而言，电机后端盖150拆卸后可以敞开变速器容纳腔120。这样可以便于对变速器400进行更换和维护。
进一步地，电机容纳腔110远离变速器容纳腔120的一端端面可以敞开，电机200安装在箱体总成100后电机后端盖150封盖电机容纳腔110。
可选地，电机壳体140和电机后端盖150以及前箱体180和后箱体190通过螺栓安装。这样不仅可以保证电机壳体140和电机后端盖150之间以及前箱体180和后箱体190之间固定连接的可靠性和稳定性，而且在电动总成1发生故障时，可以快速地拆卸箱体总成100， 进一步便于电动总成1的维护。
具体地，如图2所示，第一轴承510位于电机后端盖150上，第二轴承520和第四轴承540分别设在轴过孔130的两端，第三轴承530位于电机容纳腔110远离变速器容纳腔120的端面上。这样可以使主轴300和电机200的受力更加均匀，进一步便于提高电动总成1的结构稳定性。
更为具体地，主轴300上设有第一主轴定位槽和第二主轴定位槽，第一轴承510配合在所述第一主轴定位槽内，第二轴承520配合在所述第二主轴定位槽内。电机轴210上设有第三电机轴定位槽和第四电机轴定位槽，第三轴承530配合在所述第三电机轴定位槽内，第四轴承540配合在所述第四电机轴定位槽内。箱体总成100上设有与所述轴承相配合的箱体定位槽。这样可以利用所述定位槽对所述轴承进行定位，便于所述轴承的可靠设置，便于提高所述轴承位置的准确性。
可选地，电动总成1通过箱体总成100上的悬置安装点能够直接安装到所述车辆11的底盘上。这样进一步便于电动总成1的安装，便于提高所述车辆11的安装效率，降低所述车辆11的安装成本。
具体地，如图6所示，变速器400包括差速器组件440、第一齿轮410、第二齿轮420、第三齿轮430和传动轴450，第一齿轮410套设在主轴300上，第二齿轮420和第三齿轮430套设在传动轴450上，第一齿轮410和第二齿轮420啮合，第三齿轮430和差速器组件440啮合。这样便于变速器400实现变速传动。
可选地，如图1所示，箱体总成100包括圆筒形的电机壳体140和与电机壳体140相连的变速箱前箱体总成180，电机容纳腔110设在电机壳体140，变速器容纳腔120设在前箱体180和后箱体190，变速箱箱体从电机壳体140的外周面向外凸出。这样便于箱体总成100对电动总成1进行保护。
具体地，如图6所示，电机轴210与主轴300、传动轴450和差速器组件440的轴线平行。这样便于电动总成1顺畅地传递动力。
可选地，电动总成1还包括控制器500，控制器500安装在设在箱体总成100外，且与箱体总成100固定连接。这样便于控制器500的集成化设置，可以省去在控制器500与电机200之间设置外接三相线，便于优化电动总成1的结构，降低电动总成1的成本，避免安装外接三相线影响电动总成1的密封效果，防止电动总成1发生漏电，便于提高电动总成1的工作效率，提高电动总成1的抗干扰能力，降低电动总成1的故障率。
根据本申请的一个实施例，如图13所示，电动总成1还包括导电片20，导电片20用于连接控制器500和电机200。例如，导电片20具有控制器接线端和电机接线端，所述控制器接线端用于连接控制器500，例如连接控制器500的三相线，所述电机接线端用于 连接电机200，例如连接电机200的三相线，导电片20通过螺栓固定于控制器500。这样可以省去外接三相线和接线座，三相线长度减小，省去接线座结构，成本降低。
具体地，电机200包括电机主体203和接线装置204，接线装置204安装于电机主体203上，电机主体203具有多条引线2031，接线装置204包括多个导电片20，多个导电片20分别与对应的引线2031相连，其中，导电片20具有控制器连接端，导电片20的所述控制器连接端用于直接连接控制器500。
换言之，控制器500直接连接导电片20一端的所述控制器连接端，导电片20的另一端连接电机主体203的引线2031(引线可以是电机绕组的引线)，这样，控制器500可以控制电机主体203，并且通过导电片20连接电机控制器100和电机主体203可以使电机200的整体结构更加紧凑。
一些具体实施例中，接线装置204还包括支撑板205，支撑板205相对固定地安装于电机主体203上，支撑板205上设有定位嵌件206，定位嵌件206的两端分别伸出支撑板205上相对的两侧表面，且导电片20的一部分嵌入于定位嵌件206内，导电片20的所述控制器连接端伸出定位嵌件206。换句话说，支撑板205固定安装于电机主体203上，定位嵌件206伸出支撑板205的两侧，导电片20嵌入定位嵌件206内且两端伸出定位嵌件206一部分用于分别与引线2031和所述控制器连接端相连，其中，定位嵌件206对导电片20提供支撑定位。
进一步地，多个导电片20并排设置且相互间隔开。可以理解的是，相互间隔开的多个导电片20可以避免发生短路或者连接混乱的情况出现。
也就是说，导电件10的电机接线端与导电片20一一对应连接，导电件10与导电片20电导通，导电件10与导电片20直接连接，不需要导线或其它连接装置，这样，可以使电机总成1的线路变短，提高了抗干扰能力，且极大的节省了空间。
一个具体实施例中，导电件10与导电片20螺钉连接。螺钉连接为自锁连接，连接稳定不易松动，且拆装方便。当然，上述实施例仅是示意性的，并不能理解为对本申请保护范围的限制，例如，导电件10与导电片20之间可以是插接、卡接、焊接或铆接等。
根据本申请的另一个实施例，如图16所示，电动总成1还包括导电片20，导电片20卡接在控制器500或导电片20通过螺栓固定于控制器500。导电片20具有控制器接线端和电机接线端，所述控制器接线端用于连接控制器500，例如连接控制器500的三相线，所述电机接线端用于连接电机200，例如电机200的三相线，导电片20卡接在控制器500。这样便于导电片20的拆卸和安装，并且可以省去外接三相线和接线座，三相线长度减小，省去接线座结构，成本降低。
具体地，电机总成1包括电机200和控制器500。电机200包括电机主体203和接线 装置204，接线装置204安装于电机主体203上，所述电机主体203具有多条引线2031，所述接线装置204包括多个导电片20，多个所述导电片20分别与对应的所述引线2031相连，所述导电片20具有控制器连接端。所述电机控制器100安装于所述电机200上，所述电机控制器100具有导电件10，所述导电件10具有用于连接电源的电源连接端和用于直接连接电机200的电机连接端2212，其中，所述导电件10的电机连接端2212和所述电极片的控制器连接端中的一个具有插接结构且另一个与所述插接结构插接连接。
换言之，导电件10的电源连接端连接电源，导电件10的电机连接端2212与导电片20的控制器连接端相连，也即电机控制器100直接连接导电片20一端的所述控制器连接端，导电片20的另一端连接电机主体203的引线2031(引线2031可以是电机绕组的引线)，这样，电机控制器100可以控制电机主体203，并且通过导电片20连接电机控制器100和电机主体203可以使电机200的整体结构更加紧凑。
此外，导电件10的电机连接端2212与电机200的导电片20之间通过插接结构相连，可以理解的是，相较于绝缘线路走线的方式，插接连接方式简单，简化了工序，节省时间。而且遇到磕碰情况时可以保证电机导电片20完整，减少折弯、折断导电片20等情况的出现。
也就是说，导电件10的电机连接端2212与导电片20一一对应连接，导电件10与导电片20电导通，导电件10与导电片20直接连接，不需要导线或其它连接装置，这样，可以使电机总成1的线路变短，提高了抗干扰能力，且极大的节省了空间。
一些实施例中，导电片20上设有限位槽，所述插接结构的上设有限位凸部，所述限位凸部适于扣入所述限位槽内。所述插接结构与导电片20连接时，所述限位凸部与限位凹槽配合，这样，可以增大插接片2211与电导电片20之间的接触面积，且可以防止插接片2211在震动的过程中与导电片20之间出现短暂脱离，防止接触不良的情况出现。
