Description

一种充气气囊 技术领域
本发明涉及碰撞防护技术领域，具体涉及一种充气气囊。
背景技术
安全气囊是目前最主要使用的自动防护技术之一。被广泛运用在汽车安全防护领域，以及其他安全防护领域。目前安全气囊的作用机理，是依赖高压气瓶或化学反应器短时间内迅速产生高压气体对气囊进行充气。然后充气后的气囊在人体和撞击物之间形成一个缓冲区域，达到保护的目的。
然而制约安全气囊使用范围的一个基本特性，是气囊使用的一次性。由于传统安全气囊一次性的工作原理，一方面使气囊防护的使用成本过高；另一方面，也一定程度上影响气囊的安全性。因为是一次性且昂贵，所以气囊打开门槛的设定比较高。很多低速的交通事故，气囊都未能弹出。同样的问题也存在于将传统气囊技术运用于对人体摔倒的防护。
目前在人体防护(撞击，摔倒等)领域，世界上现有的技术和方法无外乎两类。一类是基于惰性的物理结构(区别于对突发情况主动响应，弹出或变化)，如护垫，头盔，内衬软体等。本身不含智能判断能力，也不存在收折和释放的问题。另一类是基于气囊在突发情况下迅速充气，形成气垫的保护方式。对于老年人脆弱的身体进行摔倒防护，作为老年人随身穿戴的物品，几乎不可能同时做到轻便小巧和防护周全。另外，气囊用于防摔存在重大技术缺陷，且是致命性的，难以克服。气囊技术在应用于防摔时最重要的缺点在于它的打开是一次性的。然而一次性使用，对摔倒的防护存在一个根本矛盾，就是当一个踉跄发生时，决定下一刻摔或不摔的因素包含了比如当时的地面是否湿滑，老人的生理状况，精神状况等等在内的大量不确定因素。这时气囊如果选择不打开，就可能错过了一次真正的摔倒，而选择打开，有很大概率，其实没摔倒，但气囊却废弃了。这些都必须在摔倒发生而尚未完成的一瞬间做出判断。对一次性的气囊防护技术，这是无法克服的两难困境。

具体实施方式
以下结合附图对本发明的示范性实施例做出说明，其中包括本发明实施例的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施例做出各种改变和修改，而不会背离本发明的范围和精神。同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
本发明公开了一种充气气囊，包括：气囊组件，所述气囊组件包括至少一个气室12(所述气室12的数量可以为1个、2个、3个、4个、5个以及多个等，所述气室12的数量越多，所述气囊组件的抗撞击能力越强)，所述气室壁9(气室壁9是气室12的壁)上设置有进气机构，所述进气机构连通所述气室12内腔和气室12外的空气；所述气囊组件具有收合状态和充气状态。所述充气气囊可以做一次性防护气囊使用，也可以做多次循环利用的气囊使用。
所述收合状态和所述充气状态之间可以实现往复循环变化。通过所述进气机构，所述空气可以从外部进入所述气室12内，而所述气室12内的空气不能通过所述进气机构扩散到外部，因此所述气室12能够快速的充气，当其他充满所述气室12后，所述进气机构自动关闭。
所述充气气囊还包括弹性支架和支架锁定装置，所述弹性支架与所述气囊组件的所述气室壁9相连；所述弹性支架与所述气囊组件的所述气室壁9固定连接。
当所述支架锁定装置锁定所述弹性支架时，所述弹性支架和所述气囊组件处于收合状态；
当所述支架锁定装置解锁所述弹性支架时，所述弹性支架展开并带动气囊组件充气。
所述充气气囊还包括弹性支架和支架锁定装置，所述弹性支架构成所述 气囊组件的所述气室壁9；
当所述支架锁定装置锁定所述弹性支架时，所述弹性支架和所述气囊组件处于收合状态；

所述充气气囊还包括牵引机构10，所述牵引机构10与所述气囊组件相连，所述牵引机构10带动所述气囊组件充气。
所述充气气囊包括：驱动机构，所述驱动机构与所述牵引机构10连接，驱动所述牵引机构10，所述驱动机构为所述气囊组件提供动力。
所述充气气囊在不使用时，所述气囊组件呈收合状态，当所述充气气囊使用时，通过所述驱动机构带动所述牵引机构10，所述牵引机构10带动所述气囊组件打开，同时气囊组件上的进气机构吸收空气，将所述气室12充满，所述气室12充满后，所述进气机构关闭。
所述充气气囊包括支撑机构，所述支撑机构包括至少两个支撑单元(所述支撑单元的数量可根据实际应用来确定所述支撑单元的数量，所述支撑单元的数量可以为2个、3个、4个、5个等多个)，所述支撑单元相互连接，所述支撑单元与所述气囊组件连接，所述气囊组件通过所述支撑单元相对之间发生位移形成收合状态和/或充气状态。所述支撑单元可以为板状结构，也可以为框状结构。
在一个具体实施方式中，当所述充气气囊需要展开时，所述驱动机构驱动所述牵引机构10，所述牵引机构10带动所述支撑单元和气囊组件展开，由于气囊组件迅速展开，所述气室12内部的压强小于外部的压强，因此在驱动机构驱动所述牵引机构10展开所述气囊组件时，外部的空气迅速通过所述单向进气机构8进入所述气室12内，当所述气室12内部的压强与外部压强一样时，所述单向进气机构8关闭，所述气室12自动充气完成，所述气室12的整个充气过程，不需要人为的充气，安全耗能低。
所述驱动机构驱动所述牵引机构10，所述牵引机构10带动所述支撑单元和气囊组件展开，所述支撑单元用于支撑所述气囊组件，所述气室通过所述进气机构从外界吸收空气直至所述气室内的气体充满。
在一个具体实施方式中，当所述充气气囊需要展开时，所述支架锁定装置解锁所述弹性支架，所述气囊组件自动弹开，所述气室通过所述进气机构 从外界吸收空气直至所述气室内的气体充满。
所述进气机构为从气室外向气室内腔的单向进气机构8。通过所述单向进气机构8，所述空气可以从外部进入所述气室12内，而所述气室12内的空气不能通过所述单向进气机构8扩散到外部，因此所述气室12能够快速的充气，当其他充满所述气室12后，所述进气机构自动关闭。
所述单向进气机构8可以为单向进气阀、单向通气格栅、单向百叶窗、单向透气材料以及如图2和图7所示的结构等，在本发明中对于单向进气机构8不做具体限定，只要能实现单向进气功能的都可以做本发明的单向进气机构8。
相邻的两个所述支撑单元通过连接轴连接，所述连接轴包括连接杆2和/或扭簧3，相邻的两个所述支撑单元通过所述连接轴的连接杆2和/或扭簧3收合或展开，且相邻的两个所述支撑单元之间的夹角为0-360°；相邻的两个所述支撑单元之间的夹角可以为0°、45°、90°、135°、180°、225°、270°、315°、360°。
所述弹性支架选自硬质、柔质或弹性材质中的一种或多种。
所述支架锁定装置包括锁扣和扣式固件，且所述锁扣和扣式固件位于所述弹性支架的两端，且在所述气囊组件充气后，位于两个相邻的所述弹性支架上的所述锁扣与所述扣式固件锁合。
且在所述气囊组件展开后，位于两个相邻的所述弹性支架上的所述锁扣与所述扣式固件锁合。所述气囊组件未展开时，所述弹性支架被展平或收折，不具支撑能力，所述气囊组件展开时，所述弹性支架支立起，所述弹性支架相互间形成有一定夹角的稳固结构，对撞击方向形成支撑力结构。所述弹性支架一旦展开到最大程度，所述锁扣和扣式固件将相邻的所述弹性支架结构锁合，防止所述弹性支架在受力时退回未展开状态。
所述充气气囊包括：气流通道11，所述气流通道11位于所述气囊组件内，且所述气流通道11的壁上设置有多个与所述气室12贯通的单向进气口，所述气流通道11通过从所述气流通道向所述气室内腔进气的单向进气口与所述气室贯通，即所述气流通道11通过所述单向进气口与多个所述气室12贯通；当所述气囊组件在展开时，由于所述气囊组件内的压强小于外部空气中的压强，因此空气会自动通过所述单向进气机构8进入所述气室12和所述气流通道11内，进入所述气流通道11内的空气通过所述单向进气口进入 到各个所述气室12内，以使各个所述气室12内的空气，迅速充满。
所述充气气囊还包括气体发生机构14，所述气体发生机构14与所述气流通道11连接，并向所述气流通道11充气。
所述气体发生机构14与所述气流通道11连接，所述气体发生机构14能够产生气体，并将产生的气体传输到所述气流通道11内，气体进入所述气流通道11后，通过所述气流通道11上的单向进气口进入所述气室12内，同时由于进入所述气流通道11内的气体具有一定的冲力，该冲力给于所述气囊组件一个展开的推力，所述气囊组件展开，空气通过所述气室壁9上的单向进气机构8进入所述气室12内，因此所述气囊组件能够迅速展开并充气。
在一个具体实施方式中，当需要所述气囊组件展开时，所述气体发生机构14与所述驱动机构同时启动，所述驱动机构通过所述牵引机构10带动所述气囊组件展开，同时所述气体发生机构14通过向所述气流通道11充气，给于所述气囊组件一个展开的推力，两种动力同时使用，使得所述气囊组件能够迅速展开并且迅速充气。
在一个具体实施方式中，当需要所述气囊组件展开时，所述气体发生机构14启动，所述气体发生装置产生的气体进入所述气流通道11中，然后所述支架锁定装置解锁所述弹性支架，所述气室从所述气流通道11中吸收气体，同时还通过所述单向进气机构从外界吸收空气直至所述气室内的气体充满。
所述气室壁9上设置有单向排气机构13；当所述气囊组件展开实施防护后，需要将所述气囊组件收合时，通过所述单向排气机构13将所述气囊组件内的空气排出。在本发明中对于单向排气机构13不做具体限定，只要能实现单向排气功能的都可以做本发明的单向排气机构13。
所述气室壁9由柔性可拆叠材料和/或者刚性可拆叠材料制成，以方便收合所述气囊组件，以使所述充气气囊能够循环利用。
所述气囊组件包括多个气室，所述多个气室相互连通。由于多个所述气室12相互连通，构成几何形状，所述气室12在吸收空气后，所述气室12的形状可以为三棱柱、四棱柱、五棱柱、六棱柱以及各种几何形状，因此本发明所述气室12充气后的形状具体不做限定；当所述气囊组件内的所述气室12充气后，所述气囊组件的形状可以规则的长方体、圆柱体以及不规则 等形状，因此所述气囊组件充气后的形状具体不做限定
多个所述气室12并联和/或串联；所述气室12并联设置时，多个所述气室12各自独立的通过各自的单向进气机构8吸入空气，互相不影响，当发生撞击时，部分所述气室12破坏，不会导致整体所述气囊组件丧失缓冲能力；所述气室12串联设置时，所述气室12吸收气体时，相邻的气室12不仅可以从其单向进气机构8吸收气体，同时还可以从其邻近的所述气室12吸收气体，这样所述气室12吸收气体速度快，因此气室12可以单独并联的方式连接，可以以串联的方式连接，也可以以串联和并联混合的方式组合。
所述气室壁9上设置有用于折叠所述气囊组件的折痕15，所述折痕15的数量以及形状取决于所述气囊组件的大小以及折叠方式；当所述气囊展开后需要收合时，所述气室壁9可以沿着所述折痕15将所述气囊组件压缩，使得所述气囊能够恢复展开前的状态。
本发明还提供一种可穿戴防护设备，所述可穿戴防护设备包括可穿戴基体和所述的充气气囊；其中，所述充气气囊附着于可穿戴基体上，用于人体的防护，当老人发生意外碰撞时，所述充气气囊可以展开提供缓冲，防止老人摔伤。
所述可穿戴基体包含如下至少之一：弹力海绵体、胶体、气垫。
本发明还提供一种汽车安全防护设备，所述汽车安全防护设备包括所述的充气气囊。由于所述充气气囊中的各个气室12相互独立，因此抗冲击能力以及缓冲效果较好，当汽车发生意外事故时，所述充气气囊迅速展开，以减少所述汽车受到的冲击，减少伤亡。
本发明还提供一种船舶安全防护设备，所述船舶安全防护设备包括所述的充气气囊，由于所述充气气囊中的各个气室12相互独立，因此抗冲击能力以及缓冲效果较好，当船舶发生意外事故时，所述充气气囊迅速展开，以减少所述船舶受到的冲击，减少伤亡。

所述连接轴包括连接杆2和扭簧3，两个所述底板1通过所述连接轴的连接杆2和扭簧3收合或展开，且两个所述底板1之间的夹角为0-360°；当所述气囊在不使用时，呈收合状态，相邻的两个所述底板1之间的夹角为0°，当发生碰撞时，所述驱动机构驱动所述牵引框架，两个所述底板1上的两个所述牵引框架以连接杆2为轴，分别向两个相反的方向发生位移，直至所述气囊组件充满气体，当所述气囊组件充满气体时，所述两个所述底板1呈360°展开。
所述牵引框架的两端分别位于所述连接轴的两端，即位于所述牵引框架末端的两个支架4，两个所述支架4的末端与所述连接轴的两端连接，采用这样的设置，当所述驱动机构驱动所述牵引机构10发生位移时，所述牵引机构10带动两个底板1发送位移，进而所述底板1带动所述气囊组件展开。
所述气室壁9由柔性可拆叠材料或者刚性可拆叠材料制成。
如图2所示，所述单向进气机构8为单向进气阀，所述单向进气阀包括阀本体5，位于阀本体5上的多个气孔6，以及覆盖于所述气孔6上的膜片7，所述膜片7的一端固设于所述阀本体5上，所述膜片为柔性膜片，当所述牵引框架运动时，造成所述气囊组件内外气压差，外部的气体将所述柔性膜片7顶开，所述气体通过所述气孔6流入所述气囊组件内，当所述气囊组件充满气体时，所述气囊组件内外气压差为零，所述膜片下落将所述气孔6覆盖，将气体封锁在所述气囊组件内。
本发明所述的充气气囊在不使用时，相邻的两个所述底板1呈收合状态，所述底板1将所述牵引框架以及所述气囊组件均收合在相邻的两个所述底板1之间，相邻的所述两个底板1之间的夹角为0°，当所述充气气囊使用时，通过所述驱动机构带动两个相邻所述底板1上的牵引框架分别向两个相反的方向位移，直至两个所述底板1呈360°，同时气囊组件上的单向进气阀吸收空气，将所述气室12充满，所述气室12充满后，所述单向进气阀关闭，所述牵引架以及底板1对于所述气囊组件具有支撑作用；当所述充气气囊展 开后，需要收合时，所述驱动机构给于所述牵引框架与展开时相反的驱动力，两个所述牵引框架靠拢，相邻的两个所述底板1向所述连接轴靠拢，同时通过所述单向排气机构13将所述气囊组件中所述气室12内的空气向外排出，所述气室壁9沿着所述折痕15将所述气囊组件压缩，当所述气室12内的空气排尽时，两个所述底板1收合在一起，如此即可循环利用。
