具体实施方式
下面结合附图和具体实施例对本申请作进一步说明：
参加图1和图2，流体控制组件可以应用于热管理系统，热管理系统可以为车辆热管理系统，如新能源车辆热管理系统。流体控制组件100包括驱动部件1、阀部件2、连接块3以及流道板4，阀部件2与连接块3连接，驱动部件1能够驱动阀部件2动作，驱动部件1与连接块3连接，流道板4与连接块3连接，流体控制组件100具有通道，通道的数量可以为多个，在驱动部件1的作用下，阀部件2能够控制通道中的两个或多个通断，进一步地，阀部件2在控制通道中的两个或多个连通时，阀部件2可以直通连通或节流连通通道中的两个或多个。定义直通连通为不改变或者趋于不改变(如压损范围＜1％)工作流体流过阀部件前后的压力，定义节流连通为工作流体流过阀部件前的压力大于流过阀部件后的压力，定义连接包括固定连接或限位连接或可拆卸连接或密封连接或注塑连接。
参加图2和图3，阀部件2的数量可以为多个，在本实施例中，阀部件2沿线性依次排布，阀部件2包括第一阀部件21、第二阀部件22、第三阀部件23、第四阀部件24、第五阀部件25，相应地，连接块3具有安装腔，安装腔的数量与阀部件的数量相同，在本实施例中，安装腔同样可以沿线性依次排布，安装腔包括第一安装腔31、第二安装腔32、第三安装腔33、第四安装腔34、第五安装腔35，部分阀部件位于安装腔，阀部件与连接块3连接，具体地，在本实施例中，部分第一阀部件21位于第一安装腔31，部分第二阀部件22位于第二安装腔32，部分第三阀部件23位于第三安装腔33，部分第四阀部件24位于第四安装腔34，部分第五阀部件25位于第五安装腔35。驱动部件1包括驱动机构，驱动机构的数量可以为多个，在本实施例中，驱动机构包括第一驱动机构11、第二驱动机构12、第三驱动机构13、第四驱动机构14、第五驱动机构15，驱动部件1还包括外壳体16和电路板17，外壳体16形成容纳腔160或者外壳体16形成容纳腔160的至少一部分，驱动机构和电路板17位于容纳腔160，电路板17与外壳体16连接，在本实施例中电路板17与外壳体16通过螺钉可拆卸连 接。又一部分阀部件位于容纳腔160，驱动机构位于阀部件位于容纳腔160部分的外周，驱动机构与电路板17电连接和/或信号连接，具体地，在本实施例中，第一驱动机构11套设于第一阀部件21位于容纳腔160部分的外周，第一驱动机构11与电路板17电连接和/或信号连接；第二驱动机构12套设于第二阀部件22位于容纳腔160部分的外周，第二驱动机构12与电路板17电连接和/或信号连接；第三驱动机构13套设于第三阀部件23位于容纳腔160部分的外周，第三驱动机构13与电路板17电连接和/或信号连接；第四驱动机构14套设于第四阀部件24位于容纳腔160部分的外周，第四驱动机构14与电路板17电连接和/或信号连接；第五驱动机构15套设于第五阀部件25位于容纳腔160部分的外周，第五驱动机构15与电路板17电连接和/或信号连接。
参见图2、图4以及图5，由于驱动机构的结构并无明显差别，为避免赘述，以第一驱动机构11为例进行说明，第一驱动机构11包括线圈组件111、包塑壳体112以及插针113，以线圈组件111、插针113等为注塑嵌件，一体注塑形成包塑壳体112，包塑壳体112包塑至少部分线圈组件111，插针113的一端位于包塑壳体112内与线圈组件111电连接和/或信号连接，插针113的另一端位于包塑壳体112外，与电路板17电连接和/或信号连接，从而实现第一驱动机构11与电路板17的电连接和/或信号连接。需要指出的是，作为其他实施方式，阀部件和驱动机构的数量还可以为其他，具体可根据实际应用的需要来确定。
参见图2至图5，在上述结构中，驱动部件1的驱动机构电连接和/或信号连接至同一电路板17，阀部件2连接至同一连接块3，在驱动机构和阀部件的数量为多个的情况下，这样有利于流体控制组件100的结构紧凑，同时节约材料成本。但这样导致外壳体16在长度方向的尺寸较长，连接块3在长度方向的尺寸较长，定义长度方向为阀部件2的线性分布方向，由于外壳体16为塑料材质，连接块3为金属材质，两者之间的线膨胀系数不同，随着流体控制组件100在热管理系统中运行出现温度变化时，两者沿长度方向的伸缩量不同，这样在尺寸累积的情况下，外壳体16沿长度方向的伸缩量要大于连接块3沿长度方向的伸缩量，其中电路板17与外壳体 16连接(如本实施例中通过螺钉可拆卸连接)，即电路板17随外壳体16的伸缩量从动，而驱动机构套设于阀部件2的外周，阀部件2又随连接块3的伸缩量从动，这样驱动机构通过阀部件2限位，也即驱动机构与电路板17电连接和/或信号连接的插针通过阀部件2限位，而为保证阀部件2能够更好地感应驱动机构产生的激励磁场，驱动机构的内周壁与阀部件2的外周壁贴合设置或仅留有微小间隙，这样导致电路板17在从动过程中相对插针形成位移偏差，可能导致插针与电路板17的连接点(如在本实施例中通过焊接固定连接)的应力集中，使连接点连接不牢靠，从而影响驱动机构与电路板17电连接和/或信号连接的稳定性和可靠性。需要指出的是：定义长度方向只是为方便理解而对方向的界定；另外由于外壳体16在其他方向上的尺寸相对较短，线性膨胀形成的累积偏差较小，在此不多做考虑。
为解决上述问题，参见图2、图4至图6，以第一驱动机构11为例，第一驱动机构11还包括托块114，托块114与插针113连接，在本实施例中，以插针113为注塑嵌件，一体注塑形成托块114，插针113贯穿托块114设置，沿阀部件2的轴向，托块114比电路板17靠近驱动机构设置，在本实施例中，托块114靠近插针113与电路板17电连接和/或信号连接的一端。托块114与外壳体16连接，具体地，以第一驱动机构11的托块114与外壳体16连接为例，在本实施例中，外壳体16还包括凸起筋161，沿外壳体16的宽度方向，凸起筋161自外壳体16的内壁面162朝远离内壁面162的方向凸起形成，定义宽度方向为与长度方向在同一水平面内且与长度方向垂直的方向，凸起筋161对称设置，凸起筋161形成有限位槽1611，沿外壳体16的高度方向，限位槽1611自凸起筋161的上端面向内凹陷形成，定义高度方向为与长度方向和宽度方向所在水平面垂直的方向，定义沿高度方向，凸起筋161靠近电路板17的端面为上端面。部分托块114位于限位槽1611形成的槽腔，沿外壳体16的长度方向，托块114通过限位槽1611限位。通过设置托块，并使托块114与外壳体16连接(如在本实施例中通过限位槽1611限位连接)，这样托块能够随外壳体16的伸缩量从动，且沿阀部件2的轴向，拖块与插针的连接点比插针与电路板17的连接点靠近驱动机构设置，这样有利于将插针与电路板17连接点的应力 转移或部分转移至托块114与插针113的注塑连接点，从而有利于减少插针与电路板17的连接点的应力集中，从而有利于提高插针113与电路板17电连接和/或信号连接的稳定性和可靠性。另外，在本实施例中，托块114还与电路板17抵接，设置托块114与电路板17抵接，用于对电路板17进行支撑，一方面更有利于减少插针与电路板连接点的应力集中，另一方面有利于增强电路板117强度。
参加图4、图6至图8，驱动机构与外壳体16连接，具体地，以第一驱动机构11与外壳体16连接为例，在本实施例中，第一驱动机构的包塑壳体112还包括台阶部1121，台阶部1121为非旋转体，如图4、8所示，壳体112的沿宽度方向的截面为矩形，台阶部1121的沿宽度方向的截面也为矩形，装入后，台阶部1121相对壳体112的内腔无法旋转，相应地，外壳体16还包括内卡扣165，内卡扣165同样沿外壳体16的宽度方向，自外壳体16的内壁面162向朝远离内壁面162的方向凸起形成，内卡扣165可以对称设置。沿外壳体16的高度方向，台阶部1121位于内卡扣165的卡扣部和外壳体16的底壁163之间，内卡扣165的卡扣部与台阶部1121抵接，台阶部1121与外壳体16的底壁163抵接，第一驱动机构11通过台阶部1121和内卡扣165的卡扣部配合实现与外壳体16的限位连接。设置台阶部1121为非旋转体，并使台阶部1121与外壳体16连接，一方面有利于驱动机构装配定位方便，另一方面有利于驱动机构在与阀部件2的间隙范围内随外壳体16沿长度方向从动，一定程度上也有利于减少插针与电路板17的连接点的应力集中，提高插针与电路板17电连接和/或信号连接的稳定性和可靠性。
参见图1和图9，驱动部件1还通过外壳体16与连接块3连接，具体地，在本实施例中，外壳体16还包括外卡扣164，沿外壳体16的高度方向，外卡扣164自底壁163的外壁面朝远离该外壁面的方向凸起形成，外卡扣164的数量为多个且可以对称设置，相应地，连接块3还包括卡扣槽36，沿外壳体16的宽度方向，卡扣槽36自连接块3的侧壁面向内凹陷形成，驱动部件1与连接块3连接时，外壳体16的底壁163与连接块3抵接，外卡扣164的卡扣部与卡扣槽36抵接，至少部分外卡扣164的卡扣部位于 卡扣槽36形成的槽腔。设置驱动部件1与连接块3卡扣连接，一方面有利于减少连接空间，使结构趋于紧凑和小型化，另一方面有利于外壳体16在线性膨胀伸缩时，通过卡扣槽36进行长度方向的从动，相比与外壳体16与连接块3通过螺钉或其他方式固定连接时，有利于减少外壳体16因线性膨胀而造成的应力集中，有利于提高外壳体16的使用寿命。
参见图2和图3，连接块3还包括凸起部37，在本实施例中，沿安装腔的轴向，凸起部37自连接块3的底壁朝远离底壁的方向凸起形成，定义沿安装腔的轴向，连接块3靠近流道板4的壁为底壁。凸起部37的数量可以为多个，在本实施例中，凸起部37包括第一凸起部371、第二凸起部372、第三凸起部373、第四凸起部374、第五凸起部375、第六凸起部376、第七凸起部377，凸起部37可以沿线性依次排布，凸起部37具有连通口，连接块3还具有第一通道38和第二通道39，第一通道38包括第一接口381，就连接块3单个零部件而言，第一安装腔31通过第一通道38连通第一接口381和第一凸起部371的连通口，第二安装腔32通过第一通道38连通第一接口381和第二凸起部372的连通口，第三安装腔33连通第三凸起部373的连通口和第四凸起部374的连通口，第四安装腔34通过第二通道39连通第五凸起部375的连通口和第六凸起部376的连通口，第五安装腔35通过第二通道39连通第六凸起部376的连通口和第七凸起部377的连通口。
