Description

汽车落水救生器 技术领域
本实用新型涉及一种汽车落水救生器。属于车辆配件技术领域。
背景技术
汽车落水事故，死亡率远远高于其它类型的交通事故，在分析大量事故后，发现逃出车辆和游泳上岸是要解决的两个关键问题。
市场现有的此类产品，如申请号为201711128977.1的发明专利公开了一种汽车玻璃窗爆破逃生装置，包含爆破锤、火药仓、防护罩和电弧脉冲装置，能够定向爆破，将玻璃窗击碎，快速，安全而可靠；又如申请号为201610903673.7的发明专利公开了一种用于汽车前挡风玻璃的安全气囊助力脱离装置，包含气囊控制器、引爆拉环和气囊；车内人员能够引爆安全气囊，将前挡风玻璃顶开而逃生；再如申请号为201810856578.5的发明专利公开了一种家用汽车逃生车身装置，包括顶盖和气囊，顶盖与车身通过锁销板和孔头螺栓紧固连接，顶盖能够与车身瞬间分离，打开顶盖的逃生通道，便于驾乘人员逃生，气囊在展开后，与顶盖共同形成船型结构，可作为救生艇使用。
上述专利主要都在车窗上或车顶盖上做文章，但是从事故案例中发现，上述的技术方案不能完全解决事故问题，如果车辆侧翻或者倒扣上述技术方案是无用的，有一个案例为一个水深只有0.5米两个人溺死的事故，因为车辆倒扣在水中，乘车人员来不及解开安全带就溺 死了。
上述的多个技术方案并不能根本解决人员不会游泳的问题，有一个案列为：汽车落水后，丈夫一人自己逃到岸上，因为自己不会游泳，眼睁睁看着妻子和两个孩子溺死的事故。
综上，要在根本上降低汽车落水事故死亡率，必须在逃出车辆和游泳上岸这两个方面下功夫；逃出车辆并且在逃脱的过程中，保证氧气的供给是第一步，游泳上岸或者说漂浮在水面等待救援是第二步，只有解决了这两个问题，才是一个救生器的成熟方案。

进一步的，储液室的顶部开口处设置有堵头，堵头与储液室的顶部开口为松配合。
与现有技术相比，本实用新型的有益效果是：
1、本实用新型一种汽车落水救生器，当汽车落水时，车内人员扣 住拉环拉出救生器，混合液进入反应室后与过氧化钠粉末反应产生氧气，氧气进入气囊，呼吸口阀门此时处于单向导通状态，气囊内持续增压充入氧气；落水人员落水人员用嘴含住呼吸管的外端，并用舌头顶住推杆，橡胶塞被顶出扩口结构，呼气口阀门处于双向导通状态，落水人员能够在水中进行呼吸；落水人员在水中呼吸逃出车外后，将气囊包裹在身上，气囊为落水人员提供浮力，落水人员漂浮在水面等待救援或者游泳；解决了现有落水事故中逃出车辆和游泳上岸两个难题。
2、本实用新型一种汽车落水救生器，落水人员漂浮在水面等待救援或者游泳时，为了防止推杆被误碰导致气囊内气体泄漏，落水人员将保护套套设在呼吸管外端，由于保护套的外端面具有网格状气孔，当气囊内气量不足时，落水人员直接含住保护套外端吹气，即可对气囊补气，保证了气囊的浮力。

参见图5-9，呼吸口阀门17包括阀体17.1、推杆17.3和橡胶塞17.4，推杆17.3设置在阀体17.1内，推杆17.3能够在阀体17.1内移动，橡胶塞17.4设置在推杆17.3的前部，阀体17.1的前端具有扩口结构17.5，橡胶塞17.4位于扩口结构17.5内，推杆17.3中部套设有阀内弹簧17.2，阀内弹簧17.2的一端固定在扩口结构17.5后端内壁，阀内弹簧17.2的另一端固定在推杆17.3的后部，推杆17.3的后端伸出阀体17.1的后端面；
参见图10，在正常状态时，阀内弹簧17.2处于压缩状态，橡胶塞 17.4堵住扩口结构17.5，呼吸口阀门17处于单向导通状态，即只能外界向气囊4内通气。
参见图11，给推杆17.3的后端施加一个向气囊4方向的力时，橡胶塞17.4被顶出扩口结构17.5，呼气口阀门17处于双向导通状态，即气囊4能够向外出气，外界也能够向气囊4进气。
参见图1，拉绳14的一端与反应室3的侧面连接，拉绳14的另一端设置有拉环15，落水人员只需拉动拉环15即可将储液室2、反应室3和气囊4一起拉出。
参见图3，气囊4的一侧设置有固定带4.1，固定带4.1的一端设置有卡槽4.2，固定带的另一端设置有卡扣4.3，落水人员能够将气囊包裹在身上，并用卡槽4.2和卡扣4.3固定。
工作原理：
呼吸口阀门17，阀体17.1，阀内弹簧17.2，推杆17.3，橡胶塞17.4，扩口结构17.5，保护套18，呼吸管19，积水区19.1，孔19.2
储液室2触发开关：车辆正常行驶中，储液室2、反应室3和气囊4置于外壳1内，外壳1置于汽车前排座椅下，当汽车落水时，车内人员扣住拉环15拉出救生器，由于阻挡杆10的外端通过连接绳与外壳1连接，在拉出救生器的同时，阻挡杆10抽离储液室2，此时处于压缩状态的大弹簧5将大活塞8向外顶，大活塞8带着混合液7向上移动，由于没有了阻挡杆10，混合液7给小活塞8向上的压力，使得小活塞8向上移动，最终小活塞8在限位块11的限制下停止向上移动，此时小活塞8将储液室2上端出口露出，混合液7沿着第一连接 管12进入反应室3内。
反应室3内产生氧气：混合液7为氯化钠、水和二氧化锰的混合物，反应室3内盛放有过氧化钠粉末和二氧化锰粉末，混合液7进入反应室3后与过氧化钠粉末反应产生氧气，氧气经第二连接管13进入气囊4，气囊4鼓起，由于呼吸口阀门17此时处于单向导通状态，气囊4内持续增压充入氧气。
落水人员吸氧：落水人员用嘴含住呼吸管19的外端，并用舌头顶住推杆17.3，橡胶塞17.4被顶出扩口结构17.5，呼气口阀门17处于双向导通状态，落水人员能够在水中进行呼吸。
落水人员浮于水面或者游泳：落水人员在水中呼吸逃出车外后，将气囊4利用卡槽4.2和卡扣4.3固定包裹在身上，由于气囊4内具有大量气体，能为落水人员提供浮力，落水人员漂浮在水面等待救援或者游泳时，为了防止推杆17.3被误碰导致气囊4内气体泄漏，落水人员将保护套18套设在呼吸管19外端，由于保护套18的外端面具有网格状气孔，当气囊4内气量不足时，落水人员直接含住保护套18外端吹气，即可对气囊4补气，保证了气囊4的浮力。
参见图1和图4，由于气囊4不可避免的会有液体，呼吸管19的前段开有孔19.2，即使呼吸管9前端插入气囊4内液体，此种结构可以防止液体被落水人员吸出；同时呼吸管19上设置有积水区19.1，在积水区19.1的作用下，即使有少量液体被吸入呼吸管9，此部分液体会停留在积水区19.1，从而可以杜绝了气囊4内液体被吸到落水人员嘴里的可能。
本实用新型一种汽车落水救生器，小弹簧16的一端与限位块11的顶面固定连接，小弹簧16的另一端与顶杆9的横边固定连接，小弹簧16处于压缩状态；混合液7长时间置于储液室2，混合液7中的二氧化锰会附着在储液室2内壁上，使得大活塞6沿储液室2内壁向上移动时阻力变大，此时小弹簧16向上的拉力到辅助大弹簧5推动小活塞8、混合液7和大活塞6。
本实用新型一种汽车落水救生器，储液室2的顶部开口处设置有堵头20，堵头20与储液室2的顶部开口为松配合，车辆正常行驶时，储液室2放置在外壳1内，堵头20对储液室2内部零件起到保护作用，汽车落水时，车内人员扣住拉环15拉出救生器时，由于堵头20与储液室2的顶部开口为松配合，堵20在救生器被拉出的过程中，自然脱落。
在上述实施例中，仅对本实用新型进行示范性描述，但是本领域技术人员在阅读本专利申请后可以在不脱离本实用新型的精神和范围的情况下对本实用新型进行各种修改。
