本实施例中的电子油泵主要能够为车辆润滑***和/或冷却***的工作介质提供流动的动力，具体能够为车辆传动***中的润滑***和/或冷却***的工作介质提供流动的动力。
参见图1，电子油泵100包括泵壳体、第一转子组件2、定子组件4、第二转子组件3以及电控板组件6；泵壳体设有泵内腔，第一转子组件2、定子组件4、第二转子组件3以及电控板组件6置于泵内腔，本实施例中，泵内腔包括第一腔80和第二腔90，第一转子组件2设置于第一腔80，定子组件4、第二转子组件3设置于第二腔90，定子组件4套设于第二转子组件3的外周，第一转子组件2靠近泵轴9的第一端设置，第二转子组件3靠近泵轴9的第二端设置；第一转子组件2、第二转子组件3、隔离件5以及电控板组件6沿着电子油泵的轴向排布，第二转子组件3设置于第一转子组件2以及电控板组件6之间。参见图1，定子组件4包括定子铁芯41和线圈42，电子油泵100工作时，电控板组件6通过控制通过定子组件4的线圈42中的电流按照预定的规律变化，从而控制定子组件4产生变化的激励磁场，第二转子组件3在激励磁场的作用下转动，第二转子组件3能够直接或间接地带动第一转子组件2中的部分零件转动，第一转子组件2转动时，第一转子组件2之间的液压腔的容积发生变化，使得工作介质被压出至出流口从而产生流动的动力。
参见图1，本实施例中，泵壳体包括第一壳体8、第二壳体7和第三壳体1，第一壳体8分别与第二壳体7及第三壳体1相对固定连接；本实施例中，第三壳体1与第二壳体7通过螺钉或螺栓连接，这样设置使电子油泵的拆装更加方便，从而有利于电子油泵的第一转子组件2的维修，在一实施例中，第三壳体1与第二壳体7也可以通过其他的方式连接，譬如插接、卡接等方式；第二壳体7与第一 壳体8固定连接，在一实施例中，第二壳体7与第一壳体8通过螺钉或螺栓连接，这样设置一方面使电子油泵的拆装更加方便，本实施例中，由于电控板组件6设置于第二壳体7和第一壳体8之间的空腔内，这样还有利于电子油泵中电控板组件6的维修，另一方面还可以使第二壳体7与第一壳体8的连接更可靠，在一实施例中，第二壳体7与第一壳体8也可以通过插接、卡接或等其他的连接方式。
参见图2，第一转子组件2包括第一转子21和第二转子22，第一转子21包括多个内齿，第二转子22包括多个外齿，第一转子21的内齿和第二转子22的外齿之间形成有液压腔801，本实施例中，液压腔801也是第一腔80的一部分，本实施例中，第一转子21套设于第二转子22的外周。再参见图1，电子油泵还包括进流口11和出流口12，工作介质能够通过进流口11进入液压腔801，工作介质能够通过出流口12离开液压腔801；由于第一转子21与第二转子22之间存在一定的偏心距，第二转子22在转动时，第二转子22的部分外齿与第一转子21的部分内齿啮合，从而带动第一转子21转动，在第一转子21和第二转子22旋转一圈的过程中，液压腔801内容积发生变化，当第一转子组件2从起始处转动到一个角度时，液压腔801内的容积逐渐增大从而形成局部真空，工作介质就从进流口11被吸入至液压腔801，当第一转子21和第二转子22继续转动时，原来充满工作介质的液压腔801容积逐渐减小，工作介质受到挤压，从而使得进入液压腔801内的工作介质被压出至出流口12从而产生流动的动力；本实施例中，电子油泵100还包括泵轴9，泵轴9能够带动第一转子组件2中的部分结构转动，本实施例中，泵轴9能够带动第二转子22转动，泵轴9与第二转子22连接，第二转子靠近泵轴9的第一端，泵轴9与第二转子组件3连接，第二转子组件3靠近泵轴9的第二端设置；第二转子组件3通过泵轴9带动第二转子22转动，从而实现第一转子组件2的转动，即第二转子22与第一转子21通过内外齿的啮合实现传动。
参见图1，第一腔80能够有工作介质流通，第一腔80与第二腔90连通设置，第一腔80内的部分工作介质能够进入第二腔90并与位于第二腔90内的定子组件4至少部分接触，这样使得第二腔内的工作介质能够与定子组件进行热量的交换或传递，从而有利于定子组件4的散热，在一实施例中，电子油泵100包括第一流道20和第二流道30，第一腔80内的部分工作介质能够通过第一流道20进入第二腔90并与位于第二腔90内的定子组件4接触，然后位于第二腔90内的工作介质能够通过第二流道30流出，从而使得位于第二腔90内的工作介质具有流动性，流动的工作介质更加有利于定子组件的散热；参见图1，电子油泵100还包括隔 离件5，定子组件4设置于隔离件5的第一侧，电控板组件6设置于隔离件5的第二侧，隔离件5与接线端子10固定连接，接线端子10与隔离件5的连接处密封设置，隔离件5与泵壳体之间设置有密封结构，使得隔离件5与泵壳体的连接处密封设置，第二腔90与电控板组件6所在侧不能通过接线端子10与隔离件5的连接处连通，第二腔90与电控板组件6所在侧不能通过隔离件5与泵壳体的连接处连通，这样有利于防止工作介质进入电控板组件6所在侧，从而有利于防止工作介质对电控板组件6的性能造成不良影响，进而避免影响电子油泵的性能。
参见图16，隔离件5设有沟槽50，沟槽50设置于隔离件5的外周侧壁，结合图1，电子油泵100包括密封圈70，密封圈70设置于隔离件5的沟槽50内，通过隔离件5以及密封圈70能够阻止工作介质沿着隔离件5的外周侧壁进入电控板组件6所在侧。
参见图13至图16，隔离件5包括凹槽53，凹槽53自隔离件5的上表面52凹陷设置，凹槽53未贯穿隔离件5，接线端子10穿过凹槽53，设置于凹槽53内的接线端子10的外周与形成凹槽53的内壁之间具有空隙，该空隙内填充有密封胶(未图示)；结合图1，本实施例中的电子油泵100在工作时，第二腔90内有工作介质进入，这样有利于定子组件4的散热，为了防止工作介质从接线端子10与隔离件5的连接处渗入电控板组件6所在的一侧，因此在凹槽531内填充有密封胶，这样有利于防止工作介质通过从接线端子10与隔离件5的连接处渗入电控板组件6所在的一侧；本实施例中，通过隔离件5与接线端子10的一体注塑成形实现固定连接，然后通过在凹槽53内填充密封胶进行密封，从而防止因零部件在注塑过程中产生气孔等缺陷从而使得工作介质通过气孔渗入至图1中的电控板组件6所在侧。在一实施例中，在满足注塑不产生气孔等缺陷的前提下，接线端子10也可以与隔离件5直接注塑固定实现密封，此时不需要设置凹槽53以及在凹槽53内填充密封胶进行密封。参见图1和图13，本实施例中，隔离件5位于第二壳体7的腔体内，隔离件5的至少部分外周侧壁与第二壳体7的内周侧壁紧配，从而实现隔离件5的固定。
参见图1，电子油泵100包括进流口11和出流口12，进流口11设置为供工作介质的进入，出流口12设置为供工作介质的流出，本实施例中，进流口11包括第一进流口111、第二进流口112以及第三进流口113，第一进流口111和第二进流口112连通设置，第一进流口111和第三进流口113连通设置，出流口12包括第一出流口121和第二出流口122，第一出流口121和第二出流口122连通设置，以 下将对本实施例中电子油泵的进流口11和出流口12进行具体描述。
参见图3至图6，第三壳体1包括进流口11，进流口11包括第一进流口111、第二进流口112以及第三进流口113，第一进流口111和第二进流口112连通设置，第一进流口111和第三进流口113连通设置，工作介质通过第一进流口111进入电子油泵，进入电子油泵的工作介质一部分通过第二进流口112进入图1中的第一流道20，另一部分工作介质通过第三进流口113进入图2中的液压腔801，这样设置有利于工作介质的分流；在一实施例中，一部分工作介质通过第二进流口112进入图1中的第一流道20，进而进入图1中的第二腔90并与位于第二腔90内的定子组件接触，另一部分工作介质通过第三进流口113进入图2中的液压腔801，进而使得进入液压腔801内的工作介质通过液压腔容积的变化产生流动的动力。参见图4，第三壳体1包括端面13，结合图1，端面13与第二壳体7接触设置，第三壳体1包括第一出流口121，第一出流口121自第三壳体1的端面13向远离第三壳体1的端面13方向凹陷设置，将第一出流口121向第三壳体1的端面正投影，第一出流口121的外边缘至少部分与第三壳体1的端面13的外边缘重合，这样有利于工作介质的流出；参见图7，第二壳体7设有第二出流口122，第二出流口122自第二壳体7的上表面71向远离第二壳体7的上表面71方向凹陷设置，将第二出流口122向第二壳体7的上表面71正投影，第二出流口122的外边缘至少部分与第二壳体7的外周侧壁的边缘重合，这样有利于工作介质的流出；结合图1，当第三壳体1和第二壳体7组装在一起时，第一出流口121的位置和第二出流口122的位置相对设置，从而使得第一出流口121与第二出流口122连通，从而有利于工作介质的流出。本实施例中，出流口12包括第一出流口121和第二出流口122，且第一出流口121和第二出流口122分别设置在不同的两个壳体上，这样设置有利于简化模具；在一实施例中，也可以只包括一个出流口，此时出流口可以设置第一壳体8上。
第三壳体1至少包括两个第一定位孔14，在一实施例中，参见图3至图6，本实施例中，第三壳体1包括两个第一定位孔14，第一定位孔14为通孔，第一定位孔14沿着第一壳体7的中心轴线非对称设置；第三壳体1包括第一部分15和第二部分16，第一部分15与第二部分16一体成形，第一部分15的外周直径小于第二部分16的外周直径，第一定位孔14成形于第二部分16。
