汽车座椅气动腰托用泵阀一体机
本申请要求于2019年04月01日提交中国专利局，申请号为201910256177.0，申请名称为“汽车座椅气动腰托用泵阀一体机”的中国发明专利申请的优先权，其与本申请的全部内容通过引用结合在本申请中。
技术领域
本申请属于气动腰托用气泵领域，具体涉及一种将气泵和气阀融为一体的汽车座椅气动腰托用泵阀一体机。
背景技术
近几年我国汽车工业发展势头强劲，中国已经成为继美、日之后第三个汽车年产破千万辆的国家，进入千万辆汽车大国行列。而且，随着个人家庭收入的提高，汽车已经不仅仅是机关和企业单位的办公和代步工具，汽车已经成为目前家庭消费的首选，人们除了对于汽车的品牌、安全和质量提出更高的要求外，更加重视驾驶的舒适性，这其中汽车座椅的舒适性是至关重要的。
为了减少长时间驾驶所带来的疲劳，汽车座椅上通常安装有腰托，目前市场上安装在汽车座椅上的腰托有三种，分别为手动腰托、电动腰托和气动腰托。但手动腰托需手动操作，操作扭力大，经常导致使用者感觉不便，费力；电动腰托结构复杂，零部件多，成本高，可靠性差；所以气动腰托是整个市场的理想选择。
气动腰托所用的气泵和气阀为整个气动腰托的核心部件。市场现有的大部分为气泵和气阀分开，即独立气阀与独立气泵相互间以管道等气路相连。然而，泵与阀分开形式存在以下缺点：(1)两个零部件较一个零部件需要更多运输、储存、管理等成本；(2)泵和阀之前需要用气管连接，占用空间大，且造成装配、工装、人员的成本浪费；(3)多个部件配合较单个部件可靠性也较差，气路管道等容易发生气体泄漏、脱落等不良。
中国专利CN 208010548 U公开了一种“带常开电磁气阀的泵阀一体 式微型气泵”，该气泵将泵顶盖设计成圆柱形腔体，圆柱形腔体与二位二通常开电磁气阀配合相连，使泵顶盖形成上下分别连接二位二通常开电磁气阀及气泵的结构，实现泵阀一体式结构，减少了气路管道，降低了气体泄漏等不良现象产生。然而，该结构性能过于单一，功能较少，使用气泵时不能同时实现对多个产品的充、放气。
