具体实施方式
下面结合附图和实施例对本公开作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与发明相关的部分。
需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明。
请参考图1为本实施例提供的一种复合式电磁阀，包括串联连接且一体注塑成型的泄气电磁阀401和充气电磁阀402；充气电磁阀402的第一部位区域415与气源的出气口连接；泄气电磁阀401的第二部位区域417与被充气袋连接；充气电磁阀402的第二部位区域417连接至泄气电磁阀401的第一部位区域415；充气电磁阀402上电、泄气电磁阀401断电时实现充气；充气电磁阀402断电、泄气电磁阀401上电时通过泄气电磁阀401的第三部位区域418实现排气；复合式电磁阀置于气源顶端，可与气源构成同一结构体。其中，充气电磁阀402为二位二通电磁阀，充气电磁阀402的第二部位区域417配置成向泄气电磁阀401进气，充气电磁阀402的第一部位区域415配置成让气源进气；泄气电磁阀401为二位三通电磁阀，泄气电磁阀401的第二部位区域417配置成给被充气袋充气，泄气电磁阀401的第三部位区域418配置成向空气中泄气，泄气电磁阀401的第一部位区域415配置成接收来自充气电磁阀402的气体；复合式电磁阀置于气源顶端，构成同一结构体，以便达到集成化的紧凑布置结构的目的。
其中，泄气电磁阀401的第一部位区域415为泄气电磁阀401的进气口，泄气电磁阀401的第二部位区域417为泄气电磁阀401的出气口，泄气电磁阀401的第三部位区域418为泄气电磁阀401的泄气口；充气电磁阀402的第一部位区域415为充气电磁阀402的进气口；充气电磁阀402的第二部位区域417为充气电磁阀402的出气口；此处，气源的类型，可选地，气泵、车身自带气源或者其他可作为气源的部件。
充气电磁阀402的第二部位区域417位于复合式电磁阀中间的结构连接部处，且其连接至泄气电磁阀401的第一部位区域415并与其轴向错开，且通过注塑膜芯403连接；注塑膜芯403内开设有三通口；三通口的一端与充气电磁阀402的第二部位区域417连接，一端与泄气电磁阀401的第一部位区域415连接，另一端通过密封球12密封。其中，由于充气电磁阀402的第二部位区域417和泄气电磁阀401是轴向错开的，因此两者之间只能采用设有三通口的注塑模芯3桥接式连接，桥接产生多余的气孔通过密封球12过盈配合安装堵住。
如图6所示，此处，充气电磁阀402的第二部位区域417与泄气电磁阀401的第一部位区域415还可通过连接通道416连接，进而代替三通口连接，使得充气电磁阀402的第二部位区域417与泄气电磁阀401的第一部位区域415直接实现连通，这样能够对结构达到简化的效果，在其他实施例中，还可以用其他连接部件连接充气电磁阀402与泄气电磁阀401。
充气电磁阀402的第一部位区域415安装有进气嘴，进气嘴通过U型铁11与注塑膜芯403的侧壁连接。泄气电磁阀401的第三部位区域418安装有出气嘴，出气嘴的侧壁通过U型铁11与注塑膜芯403的侧壁连接。其中，充气电磁阀402的进气嘴配置成连接气源的出气口，充气电磁阀402的出气嘴配置成连接被充气袋。U型铁11不仅将出气嘴和进气嘴与复合式电磁阀的骨架8连接，而且还具有增加磁场的效果。
如图5所示，充气电磁阀402和/或泄气电磁阀401的金属阀芯406为扁平式和花键式中的一种。采用扁平式或花键式的金属阀芯406与电磁阀壳体之间存在间隙，间隙作为电磁阀第一部位区域、第二部位区域之间的气路通道。
如图1所示，充气电磁阀402的腔体的下端为第一部位区域415，上端为第二部位区域417；腔体内从上至下依次设有硅胶帽410、金属阀芯406、弹簧409；当充气电磁阀402上电的时候，硅胶帽410随着金属阀芯406往下移动，第一部位区域415安装有进气嘴，进气嘴通过U型铁11与注塑膜芯403的侧壁连接，进气嘴与充气电磁阀402连接，再连接气源的出气口，实现充气功能，气流流经泄气电磁阀401，进而进入被充气袋，从而实现充气功能；与充气电磁阀402的结构一样的泄气电磁阀401的腔体的左下端为第一部位区域415、右下端为第三部位区域418，上端为第二部位区域417；腔体内从下至上依次设有硅胶帽410、金属阀芯406、弹簧409；第三部位区域418安装有出气嘴，出气嘴的侧壁通过U型铁11与注塑膜芯403的侧壁连接；当泄气电磁阀401上电的时候，泄气电磁阀401的金属阀芯406往上移动，第二部位区域417和第三部位区域418导通，被充气袋内的气体从第二部位区域417内进入后从第三部位区域418排出，实现泄气。
因此本实施例的技术方案不仅在一个复合式电磁阀上实现了充气和泄气，并且充气电磁阀402和泄气电磁阀401同时关断的时候，还可实现保压功能，并且在复合式电磁阀的外部还设有上壳13，对复合式电磁阀起到保护作用，进一步地，将此结构集成在一个PCB板14上，进一步提高了器件的集成度，简化了结构和安装。
具体的工作步骤具体如下：
本技术方案中，通过设计二位二通的电磁阀或者二位三通电磁阀作为充气电磁阀和二位三通的电磁阀作为泄气电磁阀，两个电磁阀形成一个电磁阀模组，具有三种工作状态：
1.如图3所示，充气电磁阀402上电、泄气电磁阀401断电，充气电磁阀402通电金属阀芯406下移，气体由气源通过充气电磁阀402的第一部位区域415进入充气电磁阀402，再由充气电磁阀402的第二部位区域417通过注塑膜芯403的通道进入至泄气电磁阀401的第一部位区域415，最后由泄气电磁阀401的第二部位区域417进入到被充气袋，实现充气；
2.如图4所示，充气电磁阀402断电、充气电磁阀402的金属阀芯406由弹簧409推动上移回位，封闭充气电磁阀402的第二部位区域，禁止气流通过；泄气电磁阀401上电，泄气电磁阀401通电金属阀芯406上移，由于充气电磁阀402的第二部位区域不再通过气体，气体由被充气袋进入泄气电磁阀401，经由泄气电磁阀401的第二部位区域417，然后由泄气电磁阀401的第三部位区域418排出，实现泄气；
3.如图1所示，充气电磁阀402断电、泄气电磁阀401断电；气体无法进入泄气电磁阀401，实现被充气袋内的气压保持。
如图2所示，本实施例提供的一种泵阀模组，包括气泵4；气泵4的每个出气口均安装有一个上述实施例中的复合式电磁阀；充气电磁阀402的第一部位区域415与气泵4的出气口连通；可选的复合式电磁阀的数量为4个，且4个复合式电磁阀集成安装在与气泵4一体化成型的壳体内。在其他实施例中，复合式电磁阀的数量可以是根据需求设置的其他数值。
可选地，泵阀模组的气路内安装有压力传感器5，压力传感器5安装在泵阀模组的气路内或者 安装在复合式电磁阀内部。压力传感器5对气路系统进行监测，以实现较复杂的控制。压力传感器5的安装位置可选以下任意一项方式：
1、安装在气泵给所有复合式电磁阀供气的气路上，配置成对气泵的供气气压进行检测；
2、安装在复合式电磁阀与被充气袋的气路上，此时压力传感器5的数量与复合式电磁阀的数量一致，分别配置成监测被充气袋内的压力；
3、压力传感器5同时安装在气泵给所有复合式电磁阀供气的气路上和复合式电磁阀与被充气袋的气路上；此时可对整个泵阀模组内各个气路的气压进行全面的监测。
本实施例提供一种汽车座椅，汽车座椅的腰托和/或侧翼支撑结构的气源由上述实施例中的泵阀模组提供，汽车座椅的腰托和/或侧翼支撑结构的气囊由复合式电磁阀充气或泄气，本实施例中的汽车座椅实现了对多路气囊的不同调节和控制。
请参考图7为本公开实施例用于汽车座椅的按摩电磁阀泵阀模组的一种实施方式的结构示意图，一种用于汽车座椅的按摩电磁阀泵阀模组20，包括：配气层23，还包括：与配气层23的出气口密封连接的电磁阀10。配气层23，连接在模组中气泵输出端，靠近气泵一端与气泵各个出气口连通，远离气泵一端设有至少一个出气口。
需要说明的是，本实施例提供的复合式电磁阀与上述实施例提供的复合式电磁阀属于同一结构。
请参考图9为本公开电磁阀进气状态的一种实施方式的结构示意图，此图所示的是电磁阀通电状态，箭头所指方向为气体流动方向。
请参考图10为本公开电磁阀排气状态的一种实施方式的结构示意图，此图所示的是电磁阀未通电状态，箭头所指方向为气体流动方向。
如图9-图11所示，电磁阀10包括：阀体本体101；阀体本体101侧壁环设有电磁线圈102。阀体本体101内设有配气腔103且配气腔103两端分别为进气口和排气口；其侧壁上设有与配气腔103连通且朝向与排气口同侧的支气道104。排气口配置有内设有气道105的排气件106且排气件106下方设有内置于配气腔103内的阀芯107；排气件106与阀芯107共同套设有第一弹性元件108；通过切换电磁线圈102通断电的状态，能够调节排气件106与阀芯107之间有无间隙。
其中：阀体本体101，为基础结构，具体地，其可以一体注塑成型。其侧壁环设有电磁线圈102。可选地，请参考图11所示的电磁阀的一种实施方式的结构示意图。阀体本体101外壁环设有容置腔110且容置腔110内绕设有电磁线圈102。当电磁线圈通电时，能够在阀体本体内周围产生磁场，以对受磁部件进行磁化，使得受磁部件之间产生相应的动作。
配气腔，设有阀体本体内部，其两端分别为进气口和排气口。进气口用于连接气体供应的结构。支气道104，设有阀体侧壁且与配气腔连通。其自由端连接有气袋30。
基于上述设计，配气腔和支气道104形成了相互连通且能够允许气体在其内部流通。阀体本体内的配置腔内设计有受磁部件，即：安装于排气口处的排气件106和设于配气腔内部的阀芯107，排气件106与阀芯之间通过第一弹性元件108连接。可选地，排气件106和阀芯107材质为铁。
可选地，阀芯107顶部中心嵌设有橡胶块，排气件106吸引阀芯107时，用于对排气件106底部密封。可选地，阀芯107底部中心嵌设有橡胶帽，当在第一弹性元件108的作用下，阀芯107复位时，用于对配气腔进口密封。
当电磁阀10通电时，阀体本体101内建立磁场，排气件106与阀芯107作为受磁部件，排气件106和阀芯107受电磁线圈所产生的磁场影响，二者近端磁性相异，固定设置的排气件106能够吸引阀芯107，排气件106与阀芯107之间无间隙，此时第一弹性元件108被压缩，固定设置的排气件106能够吸引使得阀芯107位置被提高，并暴露进气口，进气口、配气腔、支气道104形成充气通路，此状态下的电磁阀10能够经由此充气通路为气袋30充气。
当电磁线圈102处于非通电状态时，排气件106和阀芯107失去磁场的影响，阀芯106会在第一弹性元件108的作用下，向远离排气件106的方向移动至阀芯107返回至配气腔103内初始位置，以将进气口封闭，也即排气件106和阀芯107之间存在间隙，支气道104、配气腔103、气道形成泄气通路。
本实施方式中通过调节电磁线圈102是否通电的状态，能够调节排气件106与阀芯107之间是否相互吸引，最终通过切换电磁线圈102通断电的状态，能够调节排气件106与阀芯107之间有无间隙的状态。当切换电磁线圈102至通电状态时，排气件106与阀芯107之间无间隙，此时充气通路内有气体流动；当切换电磁线圈102至断电状态时，排气件106与阀芯107之间有间隙，此时泄气通路内有气体流动。将充气通路的状态切换为泄气通路的状态，能够适应气袋30的工作状态由充气状态切换为泄气状态。
支气道104与排气口在同一侧，能够使得充气端和泄气端位于同一侧，使得电磁阀的整体结构体积得以明显减小，进而使得用于汽车座椅的按摩电磁阀泵阀模组的整体结构得以进一步地减小。
请参考图13所示的用于汽车座椅的按摩电磁阀泵阀模组的一种实施方式的结构示意图。本实施例具体地对配气层进行结构优化，即：配气层23上设有至少三个出气口；电磁阀10的数量为至少三个且与出气口一一对应密封连接。

请参考图17所示的电磁阀的一种实施方式的结构示意图。还包括：纵向跨设于阀体本体101外壁的第一U型铁111；第一U型铁111上设有允许进气口和排气件106自由端暴露的通孔。
本实施方式中给出了能够增大电磁线圈所形成的磁场的磁通量，以辅助上述作业过程。具体地，U型铁，在图17中其跨设在阀体本体侧壁，也即其水平设置且其开口朝向阀体本体，其两个自由端分别与阀体本体侧壁固接。为便于进气口和排气口暴露第一U型铁111上设有允许进气口和排气件106自由端暴露的通孔。
请参考图18所示的电磁阀的一种实施方式的结构示意图。阀芯107上相对靠近排气件106的一端密封槽1072且密封槽1072内设有第一密封圈。当电磁阀能够经由充气通路为气袋充气时，排气件106和阀芯107受电磁线圈102所产生的磁场影响，二者近端磁性相异，固定设置的排气件106能够吸引阀芯107，为防止气体自二者之间的缝隙进入气道而溢出，本实施方式可选地设计有第一密封圈。
请参考图19所示的电磁阀泵阀模组的一种实施方式的结构示意图。图20为本公开复合式电磁阀保压状态的一种实施方式的结构示意图，其中图20给出了复合式电磁阀的具体结构。配气层23的至少一个出气口上配置有复合式电磁阀40；复合式电磁阀40包括：包括串联连接且一体注塑成型的泄气电磁阀401和充气电磁阀402；充气电磁阀402的第一部位区域415与气源的出气口连接；泄气电磁阀401的第二部位区域417与被充气袋连接；充气电磁阀402的第二部位区域417连接至泄气电磁阀401的第一部位区域415；充气电磁阀402上电、泄气电磁阀401断电时实现充气；充气电磁阀402断电、泄气电磁阀401上电时通过泄气电磁阀401的第三部位区域418实现排气；复合式电磁阀置于气源顶端，可与气源构成同一结构体。其中，充气电磁阀402为二位二通电磁阀，充气电磁阀402的第二部位区域417用于向泄气电磁阀401进气，充气电磁阀402的第一部位区域415用于让气源进气；泄气电磁阀401为二位三通电磁阀，泄气电磁阀401的第二部位区域417用于给被充气袋充气，泄气电磁阀401的第三部位区域418用于向空气中泄气，泄气电磁阀401的第一部位区域415用于接收来自充气电磁阀402的气体；复合式电磁阀置于气源顶端，构成同一结构体，以便达到集成化的紧凑布置结构的目的。
如图20所示，充气电磁阀402的腔体的下端为第一部位区域415，上端为第二部位区域417；腔体内从上至下依次设有硅胶帽410、金属阀芯406、弹簧409；当充气电磁阀402上电的时候，硅胶帽410随着金属阀芯406往下移动，第一部位区域415安装有进气嘴，进气嘴通过第二U型铁411与注塑膜芯403的侧壁连接，进气嘴与充气电磁阀402连接，再连接气源的出气口，实现充气功能，气流流经泄气电磁阀401，进而进入被充气袋，从而实现充气功能；与充气电磁阀402的结构一样的，泄气电磁阀401的腔体的左下端为第一部位区域415、右下端为第三部位区域418，上端为第二部位区域417；腔体内从下至上依次设有硅胶帽410、金属阀芯406、弹簧409；第二部位区域417安装有出气嘴，出气嘴的侧壁通过第二U型铁411与注塑膜芯403的侧壁连接；当泄气电磁阀401上电的时候，泄气电磁阀401的金属阀芯406往上移动，第二部位区域417和第三部位区域418导通，被充气袋内的气体从第二部位区域417内进入后从第三部位区域418排出，实现泄气。
因此本实施例的技术方案不仅在一个复合式电磁阀上实现了充气和泄气，并且充气电磁阀402 和泄气电磁阀401同时关断的时候，还可实现保压功能，并且在复合式电磁阀的外部还设有上壳，对复合式电磁阀起到保护作用，进一步地，将此结构集成在一个PCB板上，进一步提高了器件的集成度，简化了结构和安装。
本实施方式中，通过设计二位二通的电磁阀或者二位三通电磁阀作为充气电磁阀和二位三通的电磁阀作为泄气电磁阀，两个电磁阀形成一个电磁阀模组，具有三种工作状态：
1.如图22所示，充气电磁阀402上电、泄气电磁阀401断电，充气电磁阀402通电金属阀芯406下移，气体由气源通过连接通道416进入充气电磁阀402，再由充气电磁阀402的第二部位区域417通过注塑膜芯403的通道进入至泄气电磁阀401的第一部位区415，最后由泄气电磁阀401的第二部位区域417进入到被充气袋，实现充气。
2.如图21所示，充气电磁阀402断电、泄气电磁阀401上电，泄气电磁阀401通电金属阀芯406上移，连接通道416不再通过气体，气体由被充气袋进入泄气电磁阀401，经由泄气电磁阀401的第二部位区417，然后由泄气电磁阀401的第三部位区域418排出，实现泄气。
3.如图20所示，充气电磁阀402断电、泄气电磁阀401断电；气体无法进入泄气电磁阀401，实现被充气袋内的气压保持。

请参考图24和图25所示的用于汽车座椅的按摩电磁阀泵阀模组的一种实施方式的结构示意图。配气层23上还设有调压突起21且调压突起21内设有调压凹槽211；调压凹槽211底部设有与配气层23连通的调压孔212；调压突起21内配置有溢流阀22。
在该模组的结构中，为保证配气层中气体压力的稳定性，配气层中部设有与其内部连通的调压突起且调压突起内配置有具备稳压功能的溢流阀，当配气层气压大于安全阈值时气体自溢流阀处进行溢流从而使气压恢复至安全阈值内。
此外，本实施例中还公开有溢流阀的具体结构，请参考图25。溢流阀22包括：底部进入调压孔212内的溢流柱221、环设于溢流柱221外壁的限位环222、套设于溢流柱221侧壁且位于限位环222上方的第二弹性元件223和套设于溢流柱221顶部且正中开设有通槽的顶盖224；位于限位环222下方的溢流柱221侧壁套设有第二密封圈225。其中：溢流柱221，底部进入调压孔内以固定，起支撑作用，便于安装其他元件。
限位环222，设于溢流柱221外壁，将溢流柱分为位于限位环上方的第一柱段和位于限位环下方的第二柱段。第一柱段，其侧壁套设有第二弹性元件223，且其顶端套设有内部设有开设有通槽的顶盖224。第一柱段和通槽的槽壁之间设有调压间隙。通槽的底部与第二弹性元件的顶部相卡接。第二柱段，套设有第二密封圈225。
基于上述设计，当配气层内气压未超出阈值时，在第二弹性元件的作用下，溢流柱上的限位环与第二密封圈紧密接触，防止溢流阀泄气。当配气层内气压超出阈值时，气流进入溢流柱底部与调压孔之间的第一间隙，并将限位环顶起，使得第一间隙与调压凹槽连通，而后经由调压间隙排出至配气层外，实现调压目的并保证了配气层中气体压力的稳定性。
