以下将对本申请提供的膨胀阀线圈组件作进一步说明。
图1a和图1b为一实施例中提供的膨胀阀线圈组件的结构示意图，参考图1a、图1b和图3，膨胀阀线圈组件包括：线圈单元10以及外壳20。
线圈单元10上设置有安装平台110，所述安装平台上局部凸出设有连接 部100，外壳20套设于连接部100，并与安装平台110固定连接；连接部100的侧壁呈凹凸结构设置，外壳的内侧与连接部100的侧壁之间填充有密封材料。
线圈单元10可以包括绕组部件和导线部件，绕组部件包括定子极板、定子外壳、骨架及绕制在骨架上的漆包线，漆包线引出端连接在插针上，并通过注塑工艺在绕组部件外面包覆一层树脂，即包封层。线圈单元10上设置有连接部100，导线部件与绕组部件通过连接部100件连接。具体地，导线部件包括引线以及连接在引线一端的线路板，插针一端穿过预留在线路板上的小孔并使用锡焊与连接部100连接。连接部100可以与线圈单元10一体成型，当膨胀阀线圈组件处于工厂制造阶段时，线圈单元10与连接部100一体成型制造，可以加强膨胀阀线圈组件的稳固性。
外壳20套设于连接部100，并与安装平台110固定连接。具体地，外壳20罩扣在线路板的外侧并可以通过超声波焊接与安装平台110焊接在一起，以使外壳20与安装平台110熔接为一体。外壳20为绝缘外壳20，外壳20与安装平台110固定连接可以更好地密封线圈内的导线部件。
连接部100的侧壁呈凹凸结构设置。其优点为：就一个面而言，相对于将侧壁设置为平整的表面而言，将侧壁设计为凹凸结构，而可形成更多的表面。当在外壳20与连接部100之间的缝隙填充密封材料时，密封材料可与侧壁之间具有更多的接触表面，因而可促使线圈单元10内的导线部件与外界更好地密封绝缘。密封材料可以是环氧树脂或其他绝缘材料，具体材料本实施例不作限制。
连接部100侧壁可以是台阶结构、水波纹结构等凹凸结构，凹凸结构的具体形式和凹凸结构的凹凸程度本实施例不作限制，只要可以增大外壳与连接部100侧壁的结合面积即可。当膨胀阀线圈组件放置于液体中时，液体首先通过外壳与连接部100的连接处向线圈单元10内部渗透，并逐渐经由外壳与连接 部100之间的密封材料渗透至线圈单元10内部的导线部件。本实施例通过在外壳与连接部100之间的缝隙内填充密封材料，可以对液体的流动起到一定的阻挡作用，减缓液体的渗透速度，可以提高膨胀阀线圈的防水性能。另外，本实施例通过将连接部100的侧壁设置为凹凸结构，可以增加密封材料的密封面积，增加液体的渗透难度，从而可以进一步提高膨胀阀线圈的防水性能。
上述膨胀阀线圈组件，包括线圈单元10以及外壳20；线圈单元10上设置有安装平台，安装平台110上局部凸出设有连接部100，外壳20套设于连接部100，并与安装平台固定连接；连接部100的侧壁呈凹凸结构设置，外壳的内侧与连接部100之间填充有密封材料。通过将连接部100的侧壁设置为凹凸结构，可以增加密封材料的密封面积，延长液体渗透到线圈单元10内的距离，进而增加了液体渗透的难度，提高膨胀阀线圈组件的防水性能。
在一实施例中，参考图2a、图2b和图3，连接部100包括第一侧壁101、第二侧壁102、第三侧壁103以及第四侧壁104；连接部100的至少一个侧壁的表面呈凹凸结构。具体地，第一侧壁101与第三侧壁103相对设置，第二侧壁102与第四侧壁104相对设置。参见图3，外壳20为半包围的结构，即外壳20包括底面201、第一立面202、第二立面203和第三立面204。外壳20的底面201与连接部100相对设置，外壳20的第一立面202与连接部100的第一侧壁101连接，外壳20的第二立面203与连接部100的第二侧壁102连接，外壳20的第三立面204与连接部100的第四侧壁104连接，连接部100的第三侧壁103的对应位置未被外壳20罩设，通过在连接部100的第三侧壁103位置注入密封材料，以密封线圈内的导线部件。
在一实施例中，连接部100的至少一个侧壁开设有凹槽，以在连接部100的侧壁表面上形成凹凸结构。例如，可以在连接部100的任一侧壁上开设有凹 槽，也可以选择两个或三个侧壁上开设凹槽，也可在连接部100的四个侧壁上均开设凹槽。当在连接部100的四个侧壁上均开设有凹槽时，每一侧壁上的凹槽可以相连接，以在连接部100的周向形成环形凹槽，以更好地对液体进行隔离，提高膨胀阀线圈组件的防水性能。
在一实施例中，凹槽的横截面形状为开口的多边形，例如可以为三角形或四边形中的至少一种，也可以是其他不规则的形状。例如，连接部100每一侧壁上凹槽的形状均为四边形，以便于生产制造；或，连接部100第一侧壁101上的凹槽的形状为三角形，第二侧壁102上凹槽的形状为四边形。可以理解的是，连接部100每一侧壁上凹槽的形状可以为任意形状，本实施例不作限制。
在一实施例中，参见图2a和2b，第一侧壁101、第二侧壁102、第三侧壁103以及第四侧壁104上均开设有至少一条凹槽。
连接部100的四个侧壁上可以均开设多条凹槽，且不同侧壁上的凹槽的横截面的形状可以相同，也可以不同。另外，同一侧壁上的多条凹槽也可以不同。例如，第一侧壁101上开设有3条凹槽，3条凹槽的横截面的形状可以分别为三角形，四边形以及圆形/类圆形。
本实施例中，连接部100的四个侧壁上均开设有凹槽，其中，第一侧壁101上开设有第一凹槽1011，第二侧壁102上开设有第二凹槽1021，第三侧壁103上开设有第三凹槽1031，第四侧壁104上开设有第四凹槽1041。第一凹槽1011、第二凹槽1021、第三凹槽1031和第四凹槽1041的形状均为四边形，连接部100周向上形成一条环形凹槽。通过在连接部100的四个侧壁均开设有凹槽，可以在连接部100的四个侧壁表面均形成凹凸结构，从而可以增加密封材料的密封面积，可以增加膨胀阀线圈组件不同方向的液体渗透的难度，有效提高膨胀阀线圈组件的防水性能。
另外，凹槽的深度和宽度可以由本领域普通技术人员根据设计细节和需求来进行适当的改变。例如，凹槽的深度可以在凹槽的各个点处改变。
在一实施例中，同一侧壁上开设多条凹槽的深度相同；或，多条凹槽的深度呈梯度递减，或，多条凹槽的深度呈梯度递增，从而可以更好的避免液体在线圈单元10处集中，实现更好的隔离效果。本实施例中，同一侧壁上开设多条凹槽的深度相同。
在一实施例中，参见图2a和图2b，第一侧壁101、第二侧壁102和第四侧壁104上还设置有凸台。其中，第一侧壁101上设有第一凸台1012，第二侧壁102上设有第二凸台1022，第四侧壁104上设有第四凸台1042。
凸台可以与连接部100一体成型，也可以单独设置，并与连接部100的侧壁连接，且凸台单独设置时，其材质可以与连接部100的材质相同，也可以不同。凸台可以与凹槽间隔设置，以进一步增加密封材料的密封面积，延长液体渗透到线圈单元10内的距离，进而增加液体渗透的难度，提高膨胀阀线圈的防水性能。
在一实施例中，参见图4a和图4b，连接部100的第三侧壁103上还设置有第三凸台1032，从而连接部100的四个侧壁上均开设有凹槽，且还有与凹槽间隔设置的凸台。本实施例中连接部100的四个侧壁表面均形成凹凸结构，且通过凹槽和凸台的间隔设置增大了连接部100侧壁的凹凸程度，从而可以进一步增加外壳与连接部100各个侧壁的结合面积，进而增加膨胀阀线圈组件不同方向的液体渗透的难度，有效提高膨胀阀线圈的防水性能。
在一实施例中，连接部100的至少一个侧壁上设有凸台，以在连接部100的侧壁表面上形成凹凸结构。如图5a和图5b所示，第一侧壁101、第二侧壁102、第三侧壁103以及第四侧壁104上均设有至少一个凸台。其中，第一侧 壁101上设有第一凸台1012，第二侧壁102上设有第二凸台1022，第三侧壁103上设有第三凸台1032，第四侧壁104上设有第四凸台1042。
在连接部100的四个侧壁上均设有凸台，可以更大程度上增大密封材料的密封面积，进而增加膨胀阀线圈组件不同方向的液体渗透的难度，有效提高膨胀阀线圈的防水性能。
在一实施例中，凸台的横截面形状为多边形，例如可以是三角形或四边形中的至少一种，也可以是其他不规则的形状。另外，凸台的厚度可以由本领域普通技术人员根据设计细节和需求来进行适当的改变。连接部100的四个侧壁上可以均开设有多个凸台，且不同侧壁上的凸台的形状可以为三角形或四边形中的至少一种。另外，同一侧壁上的多条凹槽的形状也可以不同。例如，第一侧壁101上设有3个凸台，3个凸台的形状可以分别为三角形、四边形和圆柱形。
本实施例中，第一侧壁101、第二侧壁102和第四侧壁104上均设有两个凸台，其中，第一侧壁101上设有第一凸台1012和第五凸台1013，第二侧壁102上设有第二凸台1022和第六凸台1023，第四侧壁104上设有第四凸台1042和第七凸台1043，第三侧壁103上设有一个第三凸台1032。第一凸台1012、第二凸台1022、第四凸台1042的形状和厚度相同，第三凸台1032、第五凸台1013、第六凸台1023和第七凸台1043的形状和厚度相同。
通过在连接部100的四个侧壁均设有凸台，可以在连接部100的四个侧壁表面均形成凹凸结构，从而可以增加密封材料的密封面积，进而增加膨胀阀线圈组件不同方向的液体渗透的难度，有效提高了膨胀阀线圈组件的防水性能。
在其中一个实施例中，如图3以及图6所示，提供了另一种膨胀阀线圈组件，膨胀阀线圈组件包括：线圈单元10以及外壳20。线圈单元10上设置有 安装平台110，所述安装平台上局部凸出设有连接部100，外壳20套设于连接部100，并与安装平台110固定连接；连接部100的侧壁和/或所述外壳20的内侧呈凹凸结构设置，外壳的内侧与连接部100的侧壁之间填充有密封材料。
在其中一个实施例中，可以单独只有连接部100的侧壁呈凹凸结构设置；也可以单独只有外壳20的内侧呈凹凸结构设置；还可以连接部100的侧壁和外壳20的内侧均呈凹凸结构设置。连接部100包括第一侧壁101、第二侧壁102、第三侧壁103以及第四侧壁104；连接部100的至少一个侧壁的表面呈凹凸结构。具体地，第一侧壁101与第三侧壁103相对设置，第二侧壁102与第四侧壁104相对设置。外壳20为半包围的结构，即外壳20包括底面201、第一立面202、第二立面203和第三立面204。外壳20套设于连接部100，外壳20的第一立面202与连接部100的第一侧壁101抵靠；外壳20的第二立面203与连接部100的第二侧壁102抵靠；外壳20的第三立面204与连接部100的第四侧壁104抵靠。所述第一立面202、所述第二立面203以及第三立面204中的至少一个上设置有凹槽和/或凸台。具体地，外壳20与连接部100抵靠的第一立面202、第二立面203以及第三立面204上均呈凹凸结构设置。凹凸结构包括：台阶结构或水波纹结构。更具体的，第一立面202、第二立面203以及第三立面204上设置有立面凸台2021。第一立面202、第二立面203以及第三立面204还设置有密封凸条2022，密封凸条2022用于外壳20套设于连接部100时增强外壳20与连接部100之间密封性能，也即增强防水性能。连接部100的第一侧壁101、第二侧壁102、第三侧壁103以及第四侧壁104表面呈凹凸结构设置，具体的可以设置凹槽和/或凸台。
在其中一个实施例中，如图7-9所示，线圈单元10的插针穿过预留在线路板上的小孔与线路板连接。线路板通过引线与接头120连接，通过接头120 连接至外部装置。

以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
