Description

汽车驾驶座椅安全防护方法及装置 技术领域
本发明涉及一种汽车的安全系统，尤指一种汽车驾驶座椅安全防护方法及装置。
背景技术
'汽车安全'是汽车面世以来造车者孜孜不倦的追求！无数主动式的或者被动式的安全装置被发明出来，并不断地装配到汽车上，以期提高汽车的安全性。汽车的安全性能在近百年来不断地提升是有目共睹的，但是由于汽车性能不断地提升、使用者不断的增加以及道路的拥挤日益加重，所导致的交通事故还是有增无减，交通伤亡事故始终无法避免。综合总结所有交通事故人们不难发现，除被撞击的行人或非机动车以外，机动车驾驶员的死亡率明显高于车内其它乘客。按理说，驾驶员掌控着第一手交通情况，也更专注于交通状况，也具备第一反应的本能性自我保护而躲避直接的撞击，同时还受到安全带或者安全气囊的保护。但是，为何驾驶员的死亡率仍远高于其身旁的副驾驶座？原因就在于突出约30公分的方向盘。
这突出的方向盘毫无疑问严重挤占了驾驶员的生存空间，车祸发生时，撞击产生的巨大冲击力也使方向盘成为直接伤害驾驶员的'凶器'。不可否认，安全带和安全气囊的发明，大大地降低了驾驶员及乘客的伤亡率，但是它们仍然没有解决驾驶员被挤占的生存空间的问题。
发明内容
本发明所要解决的技术问题在于提供一种汽车驾驶座椅安全防护方法或装置，通过该方法或装置，在汽车发现撞击时，可增加驾驶员的生存空间，以便尽可能的减少驾驶员的死亡率。

具体实施方式
下面结合附图和具体实施例对本发明作进一步详述。
本发明所揭示的是一种汽车驾驶座椅安全防护方法，在驾驶座椅上安装电子触发装置，该电子触发装置在常规状态将驾驶座椅的椅座或椅背锁固；当汽车发生车祸撞击力达到预定值时，由汽车安全系统（例如安全气囊）的控制器（例如安全气囊的触发器）触发该电子触发装置，由该电子触发装置解除驾驶座椅的椅座或椅背的锁定状态，使驾驶座椅可以向后移动一定距离或者使椅背向后翻倒。当座椅向后移动或者椅背向后翻倒时，就可以增加驾驶员的生存空间，而且向后的移动力还可以缓冲向前的撞击力，达到安全防护的目的，从而减少驾驶员的死亡率。
根据上述思路，本发明设计了如下几种汽车驾驶座椅安全防护装置，如图1到图4所示，为本发明所述安全防护装置的第一较佳实施例。所述的汽车驾驶座椅安全防护装置包括与汽车安全系统的控制器电连接的电子触发装置、座椅导轨组1及安全导轨2。其中：
对于设有安全气囊的汽车来说，所述的控制器可以是安全气囊的触发器；对于没有安全气囊的汽车来说，所述的控制器可以是汽车其它安全系统的控制器，也可以是单独设置的控制器。该控制器在现有技术领域，属于根据汽车撞击触发控制的常规技术，在此不详细描述。
所述的座椅导轨组1为原有的用以调节座椅前后位置的调节机构的一部分，其功能和结构与目前汽车的座椅导轨的功能和结构相同。
所述的安全导轨2可以固定安装在汽车底盘上，位于所述座椅导轨组1的下方，且该座椅导轨组1与安全导轨2之间以可以相对前后滑移的结构配合安装。该可以相对前后滑移的结构属于本技术领域的常规结构，例如图中实施例，为相互配合的T形滑块及滑槽，在此不一一例举说明。所述的安全导轨2也可以固定安装在座椅的椅座下方，位于所述座椅导轨组1的上方，该座椅导轨组1则安装在汽车底盘之上，且该座椅导轨组1与安全导轨2之间同样以可以相对前后滑移的结构配合安装。
所述的电子触发装置可以根据不同的结构而设置，在本实施例中，该电子触发装置为电子锁3。该电子锁3安装在所述安全导轨2上，其锁舌可以插在所述座椅导轨组1的插孔11内。该电子锁也可以安装在所述座椅导轨组上，其锁舌可以插在所述安全导轨的插孔内（未予图示）。
本实施例的工作原理为（以图中所述实施例进行说明）：当汽车处于正常状态时，所述电子锁3的锁舌伸于座椅导轨组1的插孔11内，从而将座椅导轨组1固定在安全导轨2上的常规位置。在发生严重事故时，汽车的安全系统启动，例如安全气囊被触发，在安全气囊被触发的同时，所述的电子锁3受控制器的控制而解锁，使座椅导轨组1可在安全导轨2上任意前后滑移，驾驶员被固定在安全带上因惯性作用会向前冲出，而爆开的安全气囊则阻止其继续向前冲甚至于反弹回来，此时可向后滑动一定距离的座椅将起到缓冲的作用，从而增加了驾驶员的生存空间，大大减轻了撞击力。
为了不影响后座乘客的安全，驾驶座椅向下移动的距离需要考虑，正常汽车后座的腿部空间约有40公分以上，为此设定整个驾驶座椅除了正常调节的距离以外，还可以向后退20公分，向后退20公分的软靠背并不会给后座乘客（即使是有乘客的情况下）造成严重的腿部伤害。
如图5及图6所示，为本发明所述安全防护装置的第二较佳实施例。所述的汽车驾驶座椅安全防护装置包括与汽车安全系统的控制器电连接的电子触发装置、控制齿轮4及倾斜齿轮5。其中：
所述的控制器与上述第一实施例相同，在此不赘述。
所述控制齿轮4安装在驾驶座椅的椅座上，所述倾斜齿轮5安装在驾驶座椅的椅背上，两齿轮在常规状态下相互啮合，并可以受座椅角度控制装置（图中示出）控制，以便可以调节座椅椅背的角度。座椅的角度调节结构及功能也属于现有技术领域的常规技术，在此也不详细描述。
所述电子触发装置在本实施例中为电磁阀（图中未示出），该电磁阀与所述控制齿轮4的转轴6连接，当电磁阀动作时，可带动转轴6移动，并带动控制齿轮4一同移动，从而令控制齿轮4与倾斜齿轮5脱离啮合状态。
本实施例的工作原理为：当汽车处于正常状态时，所述的转轴6处于常规位置，所述控制齿轮4与倾斜齿轮5相互啮合，座椅的椅背可根据需要任意调节角度。而当发生严重事故时，汽车的安全系统启动，例如安全气囊被触发，所述控制器控制电磁阀动作，带动转轴6及控制齿轮4向远离倾斜齿轮5的一侧移动，从而使相互啮合的控制齿轮4与倾斜齿轮5脱离啮合状态，这样倾斜齿轮5失去了受力，座椅靠背完全脱离齿轮的控制，使靠背瞬间向后倒下，以此来缓冲撞击力，并大大增加了驾驶员的避险及生存空间。
如图7所示，为本发明所述安全防护装置的第三较佳实施例。本实施例是将上述第一实施例所述设置在驾驶座椅下方的安全防护装置与第二实施例所述设置在驾驶座椅靠背处的安全防护装置同时设置在一个驾驶座椅上。这样，当撞击力达到启动安全防护系统时，座椅可向后移动，同时椅背也可向后翻倒，这样可更大限度的增加驾驶员的生存空间，增加缓冲，减少死亡率。
综合上述，当发生严重碰撞事故时，绷紧的安全带将驾驶员固定在座椅上后，爆开的安全气囊，向后退的座椅以及瞬间后倒的靠背，将极大的减轻驾驶员整个胸腔的冲击力，结合这四项安全装置的触发，驾驶员所承受的撞击力将大大的减弱，其生存率的提高也是毫无疑问的。
再如图8、9所示，为本发明所述安全防护装置的第四较佳实施例，本实施例是上述第二实施例的另一种控制齿轮锁定结构。所述的汽车驾驶座椅安全防护装置同样包括与汽车安全系统的控制器电连接的电子触发装置、控制齿轮4及倾斜齿轮5，所述控制器、控制齿轮4及倾斜齿轮5的结构与相对位置均与上述第二实施例相，不再详细描述。
本实施例所不同的是，所述的电子触发装置为齿轮定位电子锁7，该齿轮定位电子锁7安装在齿轮定位器8上，该齿轮定位器8上设有一倾斜槽81，所述控制齿轮4的转轴6设置于该倾斜槽81内，且在常规状态时位于倾斜槽81的顶部。所述齿轮定位电子锁7的锁舌在常规状态伸出并抵顶于所述转轴6的下方，从而将转轴6定位在令所述控制齿轮4与倾斜齿轮5相互啮合的状态。
本实施例的工作原理为：当汽车处于正常状态时，所述的转轴6由齿轮定位电子锁7锁固在常规位置，从而令所述控制齿轮4与倾斜齿轮5相互啮合，此时座椅的椅背可根据需要任意调节角度。而当发生严重事故时，汽车的安全系统启动，例如安全气囊被触发，所述控制器控制齿轮定位电子锁7动作，令锁舌缩回，转轴6失去齿轮定位电子锁7的受力后，控制齿轮4在自身重力的作用下沿着倾斜槽81向下滑落，从而使相互啮合的控制齿轮4与倾斜齿轮5脱离啮合状态，这样倾斜齿轮5失去了受力，座椅靠背完全脱离齿轮的控制，使靠背瞬间向后倒下。
所述第四实施例构造也可以联合上述第一实施例构造共同设置于驾驶座椅上。
以上所述，仅为本发明的较佳实施例而已，并非用来限定本发明实施的范围。故但凡依本发明的权利要求和说明书所做的变化或修饰，皆应属于本发明专利涵盖的范围之内。
