具体实施方式
下面详细描述本公开的实施例，参考附图描述的实施例是示例性的，下面详细描述本 公开的实施例。
下面参考图1-图7描述根据本公开实施例的绕组组件100、车载充电器及车辆。
如图1-图3所示，根据本公开实施例的车载充电器的绕组组件100，绕组组件100具有多个引脚端子和多个连接端子。如图1所示，引脚端子可以为四个，且分别为第一端子101、第二端子102、第三端子103和第四端子104，其中，第一端子101和第二端子102可以与车辆的其中一组桥式电路(图1中的Q7、Q8、Q9、Q10为桥式电路的电气元件)电连接，第三端子103和第四端子104可以与车辆的其中另一组桥式电路(图1中的Q11、Q12、Q13、Q14为桥式电路的电气元件)电连接。如图1所示，连接端子可以为三个，且分别为第五端子105、第六端子106和第七端子107。如图1所示，第五端子105、第六端子106和第七端子107可以与整流滤波电路(图1中的Q17、Q18、Q19、Q20为整流滤波电路的电气元件)电连接。
如图2、图3所示，绕组组件100包括变压器绕组110和与变压器绕组110集成在一起的转换器绕组150。可以理解的是，变压器绕组110和转换器绕组150通过集成的形式构造成一个独立的部件，以供车载充电器使用，由此可以减少车载充电器的零部件个数，易于使车载充电器实现小型化、高功率密度设计，从而可以节省生产成本。
具体地，至少一个引脚端子与变压器绕组110直接或间接电连接。例如，如图3所示，第一端子101至第四端子104与变压器绕组110直接电连接；再如，如图5所示，第一端子101和第二端子102与变压器绕组110间接电连接，也即第一端子101和第二端子102通过第一电感绕组160与变压器绕组110电连接，第三端子103和第四端子104与变压器绕组110直接电连接；又如，如图7所示，第一端子101和第二端子102与变压器绕组110间接电连接，也即第一端子101和第二端子102通过第一电感绕组160与变压器绕组110电连接，第三端子103和第四端子104与变压器绕组110间接电连接，也即第三端子103和第四端子104通过第二电感绕组181与变压器绕组110电连接。
如图2、图3所示，转换器绕组150与变压器绕组110彼此嵌套设置，连接端子设于转换器绕组150。这里的“嵌套设置”可以理解为：转换器绕组150外套于变压器绕组110，或者变压器绕组110外套于转换器绕组150。例如，如图3所示，转换器绕组150外套于变压器绕组110的外周。
根据本公开实施例的车载充电器的绕组组件100，通过将变压器绕组110和转换器绕组150以集成的形式构造成一个独立的部件，以供车载充电器使用，由此可以减少车载充电器的零部件个数，易于使车载充电器实现小型化、高功率密度设计，从而可以节省生产成本。
根据本公开的一些实施例，如图2所示，转换器绕组150可以为铜箔冲压折弯构造成 型。需要说明的是，冲压形成的绕组结构，具有工艺简单，生产周期短的优点。此外，铜箔的厚度可以根据电流大小进行调整，进而易于使转换器绕组150适用更多型号的车载充电器。转换器绕组150包括多层铜箔，多层铜箔层叠设置。这里，对铜箔层的数量不做具体限定，主要其可满足承载的电流大小即可。
如图2和图3所示，根据本公开的一些实施例，变压器绕组110包括原边绕组111和副边绕组112，副边绕组112与原边绕组111嵌套设置。变压器绕组110还包括变压器绕线骨架120，变压器绕组110具有绕组槽121，副边绕组112和原边绕组111均设于绕组槽121内。由此，可以将副边绕组112和原边绕组111稳定地安装在变压器绕线骨架120。
如图2、图3所示，绕组组件100还可以包括第一磁路件130，第一磁路件130包括支撑部131和与支撑部131连接的连接部132，支撑部131位于变压器绕组110的下方以支撑变压器绕组110，支撑部131与连接部132构造出L型结构，连接部132的朝向变压器绕组110的表面设有第一变压器磁芯133，第一变压器磁芯133插设于变压器绕组110内。绕组组件100还可以包括第二磁路件140，第二磁路件140的构造与第一磁路件130的构造相同，第一磁路件130位于变压器绕组110的一端，第二磁路件140位于变压器的另一端，第一磁路件130与第二磁路件140粘接，以构造出环形磁回路。第一磁路件130和第二磁路件140之间设有气隙，由此可以调整电感量。需要说明的是，可以通过调整气隙的大小来调整电感量。
如图5所示，绕组组件100还包括第一电感绕组160，至少一个引脚端子与第一电感绕组160直接电连接，变压器绕组110与第一电感绕组160串联且电连接，第一磁路件130的部分位于第一电感绕组160和变压器绕组110之间。需要说明的是，第一磁路件130的位于第一电感绕组160和变压器绕组110的之间的部分可以作为共用磁路结构，该部分结构的磁通抵消。
这里需要说明的是，如图4、图5所示，第一电感绕组160、变压器绕组110和转换器绕组150集成为一个独立部件，由此可以减少车载充电器的零部件个数，一方面易于使车载充电器实现小型化、高功率密度设计；另一方面，还可以减少外接引脚的数量，从而可以节省生产成本。
在对第一电感绕组160和变压器绕组110时，可以包括两种绕法：1)第一电感绕组160的线圈绕制完后直接连续绕制变压器绕组110的原边绕组111；2)变压器绕组110的原边绕组111绕完后，直接连续绕制第一电感绕组160的线圈。这里，对引脚端子的位置不做具体限定，例如，如图2所示，引脚端子为四个，其中两个引脚端子设于第一电感绕组160，其中另外两个引脚端子设于变压器绕组110。
如图5所示，绕组组件100包括第一电感骨架170和第一电感磁芯180，第一电感绕组 160绕设于第一电感骨架170，第一电感磁芯180与第一电感骨架170连接，第一电感磁芯180的部分结构穿设于第一电感绕组160内。为了方便将第一电感绕组160绕设置于第一电感骨架170上，在一些实施例中，如图5所示，第一电感骨架170的外周壁具有绕线槽171，第一电感绕组160绕设于绕线槽171内。
为了进一步提升绕组组件100集成化程度，在一些实施例中，如图6、图7所示，绕组组件100还包括第二电感绕组181。第一电感绕组160位于变压器绕组110的一端，第二电感绕组181位于变压器绕组110的另一端，第二电感绕组181与变压器绕组110串联且电连接。其中，至少一个引脚端子与第二电感绕组181直接电连接。
需要说明的是，第二磁路件140夹设于变压器绕组110和第二电感绕组181之间，第二磁路件140位于第二电感绕组181和变压器绕组110之间的结构可以作为共用磁路结构，该部分结构的磁通相互抵消。
这里还需要说明的是，如图6、图7所示，第一电感绕组160、第二电感绕组181、变压器绕组110和转换器绕组150集成为一个独立部件，由此可以减少车载充电器的零部件个数，一方面易于使车载充电器实现小型化、高功率密度设计；另一方面，还可以减少外接引脚的数量，从而可以节省生产成本。
如图7所示，绕组组件100还包括第二电感骨架182和第二电感磁芯183。其中，第二电感绕组181绕设于第二电感骨架182，变压器绕线骨架120与第二电感骨架182连接。第二电感磁芯183与第二电感骨架182连接，第二电感磁芯183的部分结构穿设于第二电感绕组181内。
在对第一电感绕组160、第二电感绕组181和变压器绕组110时，可以包括两种绕法：1)第一电感绕组160的线圈绕制完后直接连续绕制变压器绕组110的原边绕组111，然后再绕制第二电感绕组181的线圈；2)第二电感绕组181的线圈绕制完后直接连续绕制变压器绕组110的原边绕组111，然后再绕制第一电感绕组160的线圈。这里，对引脚端子的位置不做具体限定，例如，如图7所示，引脚端子为四个，其中两个引脚端子设于第一电感绕组160，其中另外两个引脚端子设于第二电感绕组181。
为了简化车载充电器的绕组组件100，减少绕组组件100的库存部件数量，在一些实施例中，第二电感骨架182与第一电感骨架170的构造相同，第二磁路件140的构造与第一磁路件130的构造相同。此外，在一些实施例中，第一电感磁芯180和第二电感磁芯183的构造也可以相同。
