 本发明的实施方式
为了能够更清楚地理解本申请的实施例的上述目的、特征和优点，下面结合附图和具体实施方式对本申请的实施例进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请的实施例还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不限于下面公开的具体实施例的限制。
下面参照图1至图10描述根据本申请的一些实施例。
如图1所示，本实施例提出的一种油泵装置100，主要包括电机结构110和泵结构103两个部分，其中，电机结构110包括有驱动轴1101，驱动轴1101绕沿轴向延伸的轴线旋转，泵结构103则包括有泵壳体1032和泵转子，泵转子在驱动轴转动的情况下发生相同的转动，可以相对于泵壳体1032转动，从而对流体介质，例如润滑油起到一定的加压驱动效果。具体地，泵壳体1032主要包括有轴向设置的泵体105和泵盖104，泵盖104和泵体105之间设置有收纳部，用于收纳泵转子，可以理解，收纳部的一部分可以位于泵体105内，一部分位于泵盖104内，或者收纳部可完全设置在泵体105内或泵盖104内。对于泵转子而言，其包括啮合的第一转子部106和第二转子结构108，其中，第一转子部106与驱动轴1101是一体成型的，从而在装配过程中，通过泵体105对第一转子部106进行支撑，可减少零件数量，减少装配工序。
需要强调的是，如图9所示，第一转子部106采用一体式的结构，将与电机转子一同转动的驱动轴1101和与第二转子结构108配合的第一转子部106一体成型制造，并利用泵体105或利用加装的滚动轴承对第一转子部106进行支撑，通过一体成型，可极大的提高驱动轴1101与第一转子部106的同轴度，同时也可压缩第一转子部106整体的轴向尺寸。
可以理解，对于油泵装置而言，直接将驱动轴1101与泵体滑动配合，在泵体和驱动轴1101之间存在较小的间隙的基础上，润滑油会形成油膜，从而在不增加额外的轴承结构的基础上，即可起到类似于滑动轴承的效果，充分利用油泵结构103的特性，可减少轴承结构的数量，但需要补充的是，为了保证二者之间的油膜厚度，可采用较大直径的驱动轴1101，使得仅需增加一部分径向尺寸，即可极大程度的降低轴向尺寸，而油泵装置的径向尺寸通常受到电机结构110的尺寸影响，对于驱动轴1101而言，具有较大的可选范围，故而可通过增加一部分泵体105内部的径向尺寸换取整机的外部轴向尺寸，从而使得在不增加油泵装置外在的径向尺寸的基础上，实现降低整机外在轴向尺寸的效果。
其中，驱动轴1101与电机转子之间的连接方式包括但不限于过盈配合、键配合、螺纹配合、花键配合、粘胶配合等。
进一步地，通过设置电机壳102，电机壳102具有腔体，即电机腔1024，从而可为电机结构起到保护的作用，对于泵壳体而言，则会对内部设于泵腔的泵转子起到保护作用，减少受外部环境的影响，尤其是与第一转子部106一体成型的驱动轴1101可相对于泵壳体1032实现相对滑动的转动。
在一个具体的实施例中，电机壳102和泵壳体1032可以做成一体结构。
在另一个具体的实施例中，电机壳102和泵壳体1032也可以做成分体结构。
对于第一转子部106和第二转子结构108而言，通过第一齿1065和第二齿1082的啮合实现对润滑油的驱动。
在一个实施例中，第一转子部106设有外齿，即第一齿1065，第二转子结构108设有内齿，即第二齿1082。
在另一个实施例中，第一转子部106设有外齿，即第一齿1065，第二转子结构108设有外齿，即第二齿1082。
可以理解，第一齿1065和第二齿1082并不是全部啮合的，在啮合过程中，前一对齿尚未脱离啮合，后一对齿已经进入啮合，每个第一齿1065的齿面均会与第二齿1082的齿面接触，形成密闭容腔，随着第一转子部106的自转，密闭容腔的体积会发生变化，如果不能连通卸荷通道，就会形成困油容积。由于液体的可压缩性很小，当困油容积由大变小时，存在于困油容积中的液体收到挤压，压力急剧升高，同时困油容积中的液体（一般为润滑油）也从一切可泄漏的缝隙中强行挤出，使得驱动轴1101和轴承1184都会承受很大的冲击载荷，增加功率损失并使得油发热，引起噪音和振动，降低齿轮泵的工作平稳性和寿命。当困油容积由小变大时形成真空，使得溶于液体中的空气分离出来产生气泡，带来气蚀、噪音、振动、流量和压力脉动等危害。消除困油现象的方法，采用在齿轮的两端盖上开卸荷槽，使得封闭容积减小时卸荷槽与压油腔连通，封闭容积增大时通过卸荷槽与吸油腔连通。
具体地，第一转子部106通过与第二转子结构108的共轭曲线齿形轮廓的啮合，每一个齿都相互接触，同方向带动第二转子结构108转动。第一转子部106将第二转子结构108内腔分隔为多个工作腔。
进一步地，第一转子部106和第二转子结构108的中心并不重合，是偏移的，多个工作腔容积随着电机转子1102的转动发生变化，容积增大的区域形成一定真空，进油口就设置在该部位，容积减小的区域压力提高，出油口则对应设置在此处。
其中，还设置有电机腔1024和泵腔1026，通过将二者轴向分布，更便于利用电机结构的结构对泵体进行驱动，也即在电机转子1102的作用下会带动第一转子部106一同转动。
需要说明的，根据具体形状的不同，可将第一转子部106的部分设置在泵腔1026中，或者全部第一转子部106设置在泵腔1026内。
进一步地，还单独设置有轴承槽1182和轴承1184，通过限制第一转子部106的驱动轴1101上设置轴承1184，可对驱动轴1101起到一定的支撑效果。具体地，电机壳102上直接开设有轴承槽1182，将轴承1184放置到轴承槽1182内后，可直接将第一转子部106的驱动轴1101穿过轴承1184，从而实现支撑。
其中，对于轴承槽1182的位置而言，可以设置在电机结构的端部。进一步，可以设置在电机结构朝向第二转子结构108的一端，也即设置在轴向中间部位。
其中，位于轴承槽1182内的轴承1184可以为滚动轴承1184，也可以为滑动轴承1184，只要保证起到支撑作用即可。
进一步地，还单独设置有油封槽和油封，通过在驱动轴上设置油封，电机腔的部分直接开设有油封槽，将油封放置到油封槽内后，可直接将驱动轴穿过油封，从而在油封的作用下实现密封，从而起到防止液体介质流入电机结构中的效果。
其中，对于油封槽的位置而言，可以设置在电机结构的端部。进一步，可以设置在电机结构朝向第二转子结构的一端，也即设置在轴向中间部位。
在另一个具体的实施例中，同时设置有轴承槽和油封槽。
在一个具体的实施例中，如图7所示，既不设置轴承槽，也不设置油封槽。
如图1所示，本实施例提出的一种油泵装置100，主要包括电机结构110和泵结构103两个部分，其中，电机结构110包括有驱动轴1101，驱动轴1101绕沿轴向延伸的轴线旋，泵结构103则包括有泵壳体1032和泵转子，泵转子在驱动轴转动的情况下发生相同的转动，可以相对于泵壳体1032转动，从而对流体介质，例如润滑油起到一定的加压驱动效果。具体地，泵壳体1032主要包括有轴向设置的泵体105和泵盖104，泵盖104和泵体105之间设置有收纳部，用于收纳泵转子，可以理解，收纳部的一部分可以位于泵体105内，一部分位于泵盖104内，或者收纳部可完全设置在泵体105内或泵盖104内。对于泵转子而言，其包括啮合的第一转子部106和第二转子结构108，其中，第一转子部106与驱动轴1101是一体成型的，从而在装配过程中，通过泵体105对第一转子部106进行支撑，可减少零件数量，减少装配工序。
需要强调的是，第一转子部106采用一体式的结构，将与电机转子一同转动的驱动轴1101和与第二转子结构108配合的第一转子部106一体成型制造，并利用泵体105对第一转子部106进行支撑，通过一体成型，可极大的提高驱动轴1101与第一转子部106的同轴度，同时也可压缩第一转子部106整体的轴向尺寸。
其中，如图2和图8所示，第一转子部106的外端设置有轴凸部1122，同时在泵盖104上设有形状位置相对应的槽部1124，在轴凸部1122和槽部1124的配合下，轴凸部1122可作为另一个滑动配合的载体，在电机转子1102转动时，可带动轴凸部1122一同转动，使得轴凸部1122的外壁与槽部1124的槽壁相对滑动。
此外，对于轴凸部1122而言，还可对泵盖104的安装起到一定的定位作用，同时也可在径向方向上受到槽部1124的限制，从而减少径向方向的窜动。
可以理解，轴凸部1122与第一转子部106也是一体成型的，轴凸部1122可作为类似于端部轴承1184的效果，与槽部配合形成摩擦副起到支撑的效果。同时，由于轴凸部1122是直接伸入到泵盖104内的，泵盖104则设有内陷的槽部1124，同样可以在不增加轴向尺寸的基础上，利用原有结构即可实现增强支撑的效果。
可以理解，对于油泵装置100而言，直接将驱动轴1101与泵体105滑动配合，在泵体105和驱动轴1101之间存在较小的间隙的基础上，润滑油会形成油膜，从而在不增加额外的轴承1184结构的基础上，即可起到类似于滑动轴承1184的效果，充分利用油泵结构的特性，可减少轴承1184结构的数量，但需要补充的是，为了保证二者之间的油膜厚度，可采用较大直径的驱动轴1101，使得仅需增加一部分径向尺寸，即可极大程度的降低轴向尺寸，而油泵装置100的径向尺寸通常受到电机结构的尺寸影响，对于驱动轴1101而言，具有较大的可选范围，故而可通过牺牲一部分径向尺寸换取轴向尺寸的减小，从而使得在不增加油泵装置100的径向尺寸的基础上，实现降低轴向尺寸的效果。
如图4、图5和图6所示，本实施例提出的一种油泵装置100，主要包括电机结构110和泵结构103两个部分，其中，电机结构110包括有驱动轴1101，泵结构103则包括有泵壳体1032和泵转子，泵转子可以相对于泵壳体1032转动，从而对流体介质，例如润滑油起到一定的加压驱动效果。具体地，泵壳体1032主要包括有轴向设置的泵体105和泵盖104，泵盖104和泵体105之间设置有收纳部，用于收纳泵转子，可以理解，收纳部的一部分可以位于泵体105内，一部分位于泵盖104内，或者收纳部可完全设置在泵体105内或泵盖104内。对于泵转子而言，其包括啮合的第一转子部106和第二转子结构108，其中，第一转子部106与驱动轴1101是一体成型的，从而在装配过程中，通过泵体105对第一转子部106进行支撑，可减少零件数量，减少装配工序。
需要强调的是，第一转子部106采用一体式的结构，将与电机转子一同转动的驱动轴1101和与第二转子结构108配合的第一转子部106一体成型制造，并利用泵体105对第一转子部106进行支撑，通过一体成型，可极大的提高驱动轴1101与第一转子部106的同轴度，同时也可压缩第一转子部106整体的轴向尺寸。
其中，第一转子部106的外端设置有第一轴槽部1142，同时在泵盖104上设有形状位置相对应的凸起1144，在第一轴槽部1142和凸起1144的配合下，第一轴槽部1142可作为另一个滑动配合的载体，在电机转子1102转动时，可带动第一轴槽部1142一同转动，使得第一轴槽部1142的槽壁与凸起1144的外壁相对滑动。
此外，对于第一轴槽部1142而言，还可对泵盖104的安装起到一定的定位作用，同时也可在径向方向上受到凸起1144的限制，从而减少径向方向的窜动。
可以理解，第一轴槽部1142与第一转子部106也是一体成型的，第一轴槽部1142可作为类似于端部轴承1184的效果，与槽部配合形成摩擦副起到支撑的效果。同时，由于泵盖104上的凸起1144是直接伸入到第一轴槽部1142内的，同样可以在不增加轴向尺寸的基础上，利用原有结构即可实现增强支撑的效果。
在一个具体的实施例中，如图4所示，第一轴槽部1142为圆槽。
在另一个具体的实施例中，如图3所示，第一轴槽部1142为环形槽，即其槽底呈圆形或环形，通过将第一轴槽部1142的中心线设置在驱动轴1101上，使得在第一转子部106受电机转子1102带动转动的情况下，第一轴槽部1142会与泵盖104上的凸起1144相配合。
可以理解，由于第二转子结构108套设在第一转子部106的径向外侧，为了实现加压驱动的效果，会将第二转子结构108相对于第一转子部106偏心设置。
需要强调的是，第一转子部106采用一体式的结构，将与电机转子1102一同转动的驱动轴1101和与第二转子结构108配合的第一转子部106一体成型制造，并利用泵体对第一转子部106进行支撑，可极大的提高驱动轴1101与第一转子部106的同轴度，同时也可压缩第一转子部106整体的轴向尺寸。
如图1所示，本实施例提出的一种油泵装置100，主要包括泵体105和位于泵体105一端的泵盖104，泵体105具有泵腔1026，一方面可对内部的结构起到保护的作用，减少受外部环境的影响，可对内部的第一转子部106、第二转子结构108和电机结构起到支撑作用，尤其是第一转子部106的驱动轴1101可相对于泵体105实现相对滑动的转动。具体地，电机结构主要包括有同轴的电机转子1102和电机定子1104，电机定子1104固定设置在泵体105内，电机转子1102则可相对于电机定子1104发生转动，此时，由于在泵腔1026内还设有一体的第一转子部106，驱动轴1101可直接伸入电机转子1102，使得电机转子1102在电机定子1104作用下转动时，会带动第一转子部106一同发生转动，进而实现与第二转子结构108的配合，从而对第一转子部106和第二转子结构108之间的润滑油起到一定的加压驱动效果。
其中，如图6所示，第一转子部106的内端设置有第二轴槽部1162，同时在泵体105的相对位置上设有形状相适配的配合部1164，在第二轴槽部1162和配合部1164的配合下，第二轴槽部1162可作为另一个滑动配合的载体，在电机转子1102转动时，可带动第二轴槽部1162一同转动，使得第二轴槽部1162的槽壁与配合部1164的外壁相对滑动。
此外，对于第二轴槽部1162而言，还可对泵盖104的安装起到一定的定位作用，同时也可在径向方向上受到凸起1144的限制，从而减少径向方向的窜动。
需要强调的是，第一转子部106采用一体式的结构，将与电机转子1102一同转动的驱动轴1101和与第二转子结构108配合的第一转子部106一体成型制造，并利用泵体对第一转子部106进行支撑，可极大的提高驱动轴1101与第一转子部106的同轴度，同时也可压缩第一转子部106整体的轴向尺寸。
在上述任一实施例的基础上，在泵盖104上设置贯通的输油通道1042，可在不拆开泵盖104的情况下，向泵腔1026内输入润滑油。具体地，输油通道1042和第一转子部106与第二转子结构108之间的间隙在轴向方向上是存在重叠区域的，故而通过在泵盖104的外端面输入润滑油，润滑油会沿输油通道1042流入第一转子部106和第二转子结构108中。
在上述任一实施例的基础上，对第一转子部106的径向尺寸进行限定，限定第一转子部106的径向尺寸更大，以便于与第二转子结构108进行配合，从而实现油泵的作用。
在上述任一实施例的基础上，如图2所示，驱动轴1101可直接选用光轴，便于加工，或者如图5所示，选用阶梯轴，可根据阶梯实现轴向定位，便于装配。
在选用阶梯轴的基础上，可利用台阶部分的结构，对台阶部分进行再次加工，例如可设置滚动轴承，或者设置密封结构等。
在上述任一实施例的基础上，电机结构110主要包括有同轴的电机转子1102和电机定子1104，电机定子1104固定设置在电机壳102内，电机转子1102则可相对于电机定子1104发生转动，此时，由于在泵腔1026内还设有一体的第一转子部106，驱动轴1101可直接伸入电机转子1102，使得电机转子1102在电机定子1104作用下转动时，会带动第一转子部106一同发生转动，进而实现与第二转子结构108的配合，从而对第一转子部106和第二转子结构108之间的润滑油起到一定的加压驱动效果。

其中，传动结构204可以为发动机、减速器、二合一电驱动系统和三合一电驱动系统总成中的一个或多个。
其中，车辆200可以为特种车辆200，且车辆200具有油泵装置100的所有优点。值得说明的是，车辆200可以为传统的燃油车，也可以为新能源汽车。其中，新能源汽车包括纯电动汽车、增程式电动汽车、混合动力汽车、燃料电池电动汽车、氢发动机汽车等。
