实施例
如图1所示，本发明提供了一种汽车座椅气阀，包括：壳体100，其内设有第一气腔200和第二气腔500；中转气腔300，其设置在所述壳体100内，并与所述第一气腔200和所述第二气腔500均连通，且中转气腔300与气囊连通；记忆合金阀组件700，其设置在所述中转气腔300中，适于在升温后收缩，使所述中转气腔300与所述第一气腔200导通，或使所述中转气腔300与所述第二气腔500导通。
本汽车座椅气阀在壳体100内设置有进气腔210和中转气腔300，并充分利用中转气腔300的空间，将记忆合金阀组件700设置在了中转气腔300中，实现了小型化和轻量化。
如图1所示，所述第一气腔200包括：进气腔210；所述中转气腔300上开有连通所述进气腔210的进气通道310和通向气囊的常开通道320；所述记忆合金阀组件700可以包括：进气记忆合金阀组件400，其设置在所述中转气腔300中，适于在通电升温后收缩并打开所述进气通道310，以将从所述进气腔210进入所述中转气腔300的气体导入所述常开通道320。
如图1和图2所示，所述第二气腔500可以包括：出气腔510；所述中转气腔300上开有连通所述出气腔510的排气通道330；所述记忆合金阀组件700还可以包括：排气记忆合金阀组件600，其设置在所述中转气腔300中，以使气囊内的气体经所述常开通道320进入所述中转气腔300，并从所述排气通道330排入所述出气腔510。参考图1和图2，并列设置有三个所述中转气腔300，三个所述中转气腔300均通过各自的进气通道310与所述进气腔210连通，均通过各自的排气通道330与所述出气腔510连通，通过设置多个中转气腔300，可组成阀组，为气囊提供多路供气、排气。
如图1所示，所述壳体100可以包括：上盖110、壳身120和下盖130；所述进气腔210、中转气腔300、出气腔510设置在所述壳身120上；所述上盖110和下盖130适于在盖合所述壳身120时密封所述进气腔210、中转气腔300、出气腔510；通过设置上盖110、壳身120、下盖130，可以在将进气记忆合金阀组件400和排气记忆合金阀组件600装入中转气腔300中后，最后盖合上盖110，完成组装。
如图3和图2所示，所述中转气腔300内设有贴合中转气腔300一侧壁的阀组件仓座340，所述上盖110的盖合面设有阀组件仓盖111，以在所述上盖110盖合后形成阀组件仓350，并在阀组件仓350的仓外形成凵形气道360；所述进气通道310和所述常开通道320开设在所述凵形气道360同一窄端侧的中转气腔300的腔壁上；所述排气通道330开设在所述凵形气道360另一窄端侧的中转气腔300的腔壁上。即所述阀组件仓座340也为凵形 板，其通过与中转气腔300一侧壁贴合来围成阀组件仓350，以削减掉阀组件仓座340一侧壁，减少相应的体积和重量占用；阀组件仓座340与阀组件仓盖111所形成的阀组件仓350，可在中转气腔300内隔离出空间更小的凵形气道360，如图3所示，并结合图1，所述进气通道310和所述常开通道320开设在所述凵形气道360同一窄端侧的中转气腔300的腔壁上，具体的，所述常开通道320位于所述进气通道310的下方，常开通道320与进气通道310之间无转角，进气时，进气记忆合金阀组件400将进气通道310打开，进入凵形气道360的气体可直接进入常开通道320中，无额外阻力，而排气时，排气记忆合金阀组件600将凵形气道360另一窄端侧的排气通道330打开，气囊内的气体排出时需要经过凵形气道360的两个转角，排气阻力较大，从而得到进气较为迅速而排气较为缓慢的舒适供排效果。
如图5所示，所述阀组件仓座340朝向所述进气通道310的侧壁上开有进气阀下缺口371，如图4所示，所述阀组件仓盖111相应处开有进气阀上缺口372，参考图7，以在盖合后形成进气阀穿装通道373；如图5所示，所述阀组件仓座340朝向所述排气通道330的侧壁上开有排气阀下缺口381，如图4所示，所述阀组件仓盖111相应处开有排气阀上缺口382，参考图7，以在盖合后形成排气阀穿装通道383；从而将进气记忆合金阀组件400和排气记忆合金阀组件600装入中转气腔300中后，盖合上盖110，完成组装；如图6所示，所述进气记忆合金阀组件400还可以包括：进气通电端子410，其设置在所述阀组件仓350的仓底；进气弹簧片420，其一端设置在所述阀组件仓350的仓底；进气记忆合金连接部430，其设置在所述进气弹簧片420的另一端，并通过进气记忆合金丝440与所述进气通电端子410斜拉连接；进气堵头450，其与所述进气通道310适配，并小于所述进气阀穿装通道373，参考图7，以在所述进气记忆合金丝440收缩斜拉进气记忆合金连接部430时通过所述进气阀穿装通道373；具体的，参考图7，进气堵头450略小于进气阀穿装通道373，在被斜拉后不会碰壁即可，同样，排气堵头650也略小于排气阀穿装通道383，在被斜拉后不会碰壁即可。
如图6所示，所述排气记忆合金阀组件600还可以包括：排气通电端子610，其设置在所述阀组件仓350的仓底，并位于所述进气弹簧片420旁；排气弹簧片620，其一端设置在所述阀组件仓350的仓底，并位于所述进气通电端子410旁；排气记忆合金连接部630，其设置在所述排气弹簧片620的另一端，并通过排气记忆合金丝640与所述排气通电端子610斜拉连接；排气堵头650，其与所述排气通道330适配，并小于所述排气阀穿装通道383，参考图7，以在所述排气记忆合金丝640收缩斜拉排气记忆合金连接部630时通过所述排气阀穿装通道383。进气记忆合金阀组件400与排气记忆合金阀组件600通过如此交 错设置，可共用阀组件仓350，图7中的虚线部分为斜拉前的进气堵头450与排气堵头650，需要说明的是，图7中的进气堵头450和排气堵头650同时被斜拉打开仅是示意，并非实际工作情形。如图7和图3所示，所述进气堵头450被斜拉后可将进气通道310打开，此时阀组件仓350也通过进气堵头450与进气阀穿装通道373之间的间隙连通凵形气道360，且此时的间隙较进气堵头450被斜拉前更小，可防止新鲜空气剧烈涌入阀组件仓350内，导致进气记忆合金丝440温度波动，从而保证进气记忆合金丝440稳定地升温变形；当进气通电端子410通电一定时间，气囊充满后，进气通电端子410断电，进气记忆合金丝440恢复原有形状，进气弹簧片420复位，进气堵头450堵住进气通道310，使气囊保压，进气堵头450与进气阀穿装通道373之间的间隙也恢复原来大小，阀组件仓350与凵形气道360可正常进行热交换，防止阀组件仓350积热；当该气囊排气时，使排气通电端子610通电一定时间，排气堵头650被斜拉将排气通道330打开后，气囊内的气体绝大部分直接经凵形气道360排出，只有少部分会经过阀组件仓350后再进入凵形气道360排出，同样能够防止气囊中的空气剧烈涌入阀组件仓350内，导致排气记忆合金丝640温度波动，从而保证排气记忆合金丝640稳定地升温变形；当排气通电端子610通电一定时间后，排气通电端子610断电，排气记忆合金丝640恢复原有形状，排气弹簧片620复位，排气堵头650堵住排气通道330，排气堵头650与排气阀穿装通道383之间的间隙也恢复原来大小，阀组件仓350与凵形气道360可正常进行热交换，防止阀组件仓350积热。
如图1所示，所述第一气腔200还可以包括：缓冲柱形腔220，其上部与所述进气腔210连通，下部连接有一进气嘴230；新鲜空气经进气嘴230进入缓冲柱形腔220缓冲降压后，再进入进气腔210，减少进气噪音；如图7所示，所述常开通道320内设有进气消音填充物240，如图2所示，所述出气腔510内设有出气消音填充物250，进一步减少噪音。
此外，本实施例还提供了一种汽车座椅气阀的工作方法，包括：如上所述的汽车座椅气阀；在壳体100内设置第一气腔200、第二气腔500和中转气腔300；其中，中转气腔300与所述第一气腔200和所述第二气腔500均连通，且中转气腔300与气囊连通；通过记忆合金阀组件700通电升温后收缩，使所述中转气腔300与所述第一气腔200导通，或使所述中转气腔300与所述第二气腔500导通。
本汽车座椅气阀的工作方法涉及的部件及工作过程和工作效果见上文，此处不再赘述。
另外，本实施例还提供了一种汽车座椅，包括：如上所述的汽车座椅气阀；气囊，其设置在座椅中，并与所述汽车座椅气阀连通。
本汽车座椅中的汽车座椅气阀控制气囊充气或排气涉及的部件及工作过程和工作效 果见上文，此处不再赘述。
综上所述，本发明提供的汽车座椅气阀，在壳体内设置有进气腔和中转气腔，并充分利用中转气腔的空间，用阀组件仓座和阀组件仓盖将其隔离成阀组件仓与凵形气道，形成进气时无额外阻力，进气较为迅速，排气时阻力较大，排气较为缓慢的舒适供排效果，同时将进气记忆合金阀组件与排气记忆合金阀组件交错设置，共用一个阀组件仓，但通过进气堵头斜拉引起的，进气堵头与进气阀穿装通道之间间隙的变化，可保证进气时进气记忆合金丝稳定地升温，进气结束后阀组件仓与凵形气道又能正常地进行热交换，防止阀组件仓积热。此外，通过设置缓冲柱形腔、消音填充物，减小供气、排气时的噪声，通过设置进气弹簧片、排气弹簧片，减小了撞击噪音，提高使用感受。
