TPF09-01-2699 车辆安全气囊讯号撷取系统
技术领域
本发明涉及一种车辆安全气囊讯号撷取系统，尤其涉及一种用于车祸中，车 辆的安全气囊爆开时， 撞击讯号撷取的技术， 具体而言指一种在车祸撞击中， 藉 由装设于安全气囊外缘等处的撷取单元设计， 当安全气囊爆开时， 撷取单元而能 以压掣压掣开关、 以拉扯拉动开关或以感测器感测， 如温度、 声响等， 而能撷取 到车辆撞击讯号， 进而开启外加式装置， 如用于防止车辆发生火灾的预防装置等 给车辆， 在车祸中可提升安全防护层次， 使乘员生命能获得更高保障。 背景技术
按，车辆只要尚需由人为操控驾驶，车祸发生就无法避免；但车辆整体性能、 安全与配备， 日新月异， 如加强车体结构、 配备多颗安全气囊等， 蔚为流行； 安 全气囊被研发使用迄今已有二十多年， 已是相当成熟稳定技术； 全球除了亚洲地 区以外， 其他地区几乎已列为基本配备， 当车辆发生车祸撞击时， 引爆安全气囊 作动是经由电子控制单元 （Electronic Control Unit ECU) 管控， 在处理撞击 讯号后， 点燃底火与充气剂， 使高压钢瓶能瞬间 （约 45毫秒内） 充气， 提供安 全防护； 早期车辆只配备两颗安全气囊， 至今已有多颗安全气囊配置， 供车辆遭 不同部位撞击时， 引爆相关安全气囊， 提供更高层次安全防护； 多颗安全气囊配 置， 相对电子控制单元 （ECU) ， 也需配合设计， 足见电子控制单元 （ECU) 是依 需求渐而设计开发； 由于驾驶员与方向盘相近， 安全气囊在爆开时， 以超过时速 300公里以上速度冲向驾驶员， 因此， 方向盘安全气囊容量遭限制， 而安全气囊 容量越大， 安全防护程度越佳， 所以， 方向盘的安全气囊， 有改良的空间， 方向 盘如能采自动溃缩设计，在车祸时，抵销冲向驾驶员冲击力与增大安全气囊容量， 则是很好构想； 除此之外， 车辆更应朝如何使乘员在车祸中， 减少惯性撞击力与 碰撞方向发展， 以保障乘员生命安全。
车祸撞击， 容易引发车辆火警事故； 又随油价高涨与温室效应， 电动车、 电 动巴士…等已蔚为主流，但电动车辆存在有使用中、充电中与静止无故着火实例， 更因车祸中， 专用电瓶遭撞击破裂而短路、 着火事故； 中东地区等恐怖攻击或遭 纵火…，车辆有容易着火与迅速蔓延特性，车辆备有自动灭火装置应是基本需求; 车厂对所配用车用电子系统与装置， 力求完整， 如出现线路遭擅改而影响原有功 能， 往往是车主损失与责任问题困扰； 现车用电子， 如配置视讯 （DVD ) 、 卫星 导航 （GPS ) 、 ( 3G) 通讯等配备是时潮趋势， 如能整合这些配备功能， 可创造 出其他功效， 例如整合卫星导航 （GPS ) 、 ( 3G) 通讯等装置， 在车祸中， 可自 动报案， 并由卫星导航 （GPS ) 定位而施予救援， 足见目前车辆在安全防护上， 仍有缺口， 即待填补。
如图 1所示，习知的车辆安全气囊 20作动过程如下：由电门锁 90控制启动、 行驶车辆， 如发生车祸撞击时， 装置于车上的检知元件 11， 如撞击感测器， 检 知撞击讯号后， 经讯号导线 15传至电子控制单元 （ECU) 10 内处理输出讯号， 由讯号导线 15引爆安全气囊 20， 提供安全防护， 如图 1所示； 因实际需求发展， 车辆已配置多颗安全气囊 20， 以符合车祸出现前方撞击或侧边撞击等需求。
又如图 2所示， 如将外加式装置 30， 如自动灭火装置…的电源线 35， 擅接 于安全气囊 20讯号导线 15上， 如藉以撷取电子控制单元 （ECU) 10引爆安全气 囊 20作动的撞击讯号，则无法启动外加式装置 30，并将造成电子控制单元（ECU) 10与安全气囊 20失灵； 而外加式装置 30， 如为自动灭火装置， 如采用电磁阀为 开启灭火装置， 在火警需一段时间灭火工作与电磁阀通电开启、 断电则关闭背景 下， 电子控制单元 （ECU) 10采瞬间电流引爆安全气囊 20设计是无法配合； 又 所述外加式装置 30启动方式亦采前述安全气囊 20点燃底火与充气剂，使高压钢 瓶（亦可为灭火钢瓶）能瞬间充气致动技术， 如欲并联安全气囊 20讯号导线 15， 因由电子控制单元（ECU)输出瞬间启动讯号， 一分为二， 结果造成两者皆异常， 反而无法保证提供安全防护。 发明内容
缘是， 本发明在于解决现有安全气囊车辆， 在车祸中， 当安全气囊爆开， 藉以低成本、 简单的撷取讯号装置， 能同步撷取撞击讯号， 有效启动外加式装置 等， 如用于防止车辆发生火灾的预防装置等， 而能提供更高层次安全防护。
本发明主要藉由下列的技术手段，来具体实现前述的功效与目的，其包括有: 一组电子控制单元（ECU)； 于车辆上置有多个可感测车祸撞击的检知元件， 当车祸撞击时， 电子控制单元 （ECU) 能处理检知元件传回撞击讯号， 引爆安全 多个安全气囊； 包含配置于驾驶座、 乘客座、 左、 右侧边帘幕等安全气囊， 藉讯号导线与电子控制单元 （ECU) 连线， 当车辆发生不同部位撞击时， 透过电 子控制单元 （ECU) 处理而能引爆相关部位安全气囊， 提供安全防护；
多个撷取单元； 能与外加式装置与独立电瓶连线， 撷取单元藉安全气囊爆开 时， 以压掣开关或以拉线拉扯开关方式， 或以感测器感测， 如温度、声响等方式， 启动加式装置。 一或多个外加式装置， 其为安全防护装置， 如车辆的方向盘退缩装置、车辆 座椅安全防护装置、 用于防止车辆发生火灾的预防装置等安全防护装置；

依前述所言， 安全气囊 20已是相当成熟、 稳定的车用安全装置， 其是利用 电流点燃底火与充气剂， 而使高压钢瓶能于瞬间 （约 45毫秒） 释放高压气体使 安全气囊 20充气， 同理， 藉此技术， 例如高压钢瓶内充填灭火气体且有一定容 量， 则高压钢瓶成为能自动灭火的灭火器， 藉撷取单元 5作动， 而高压钢瓶同时 开启， 形成自动灭火效果， 其他外接式装置 30配合此技术， 而能发挥原设计功 效。
而撷取单元 5， 设置于安全气囊 20本体外缘上或相邻部位处， 当安全气囊 20爆开时， 可启动撷取单元 5与外接式装置 30 ; 而撷取单元 5有多种型式设计， 详述如下：
请先参阅图 4〜图 6所示， 有一压掣元件 50， 含有一固设于安全气囊 20相 邻部位处壁面的基板 51， 且基板 51两侧搭配一组连杆件 53， 支撑有一压板 52， 压板 52对应未作动的安全气囊 20表面，且基板 51与压板 52间设有一微动压掣 开关 55， 其中压板 52与微动压掣开关 55间保持有一微小间距且使微动压掣开 关 55呈断电状态， 当安全气囊 20爆开充气过程， 必压掣压板 52， 使微动压掣 开关 55经压掣后有一段时间通电；
又如图 7、 图 8所示， 撷取单元 5另一型式设计， 有一拉扯元件 60， 含有一 微动伸出开关 61， 微动伸出开关 61有一可伸缩的作动杆 62， 微动伸出开关 61， 由一压框 65套住于定位卡座 67上， 使作动杆 62内缩而呈现断路状态， 压框 65 由一拉线 66环套安全气囊 20本体外缘上， 拉线 66另一端固设微动伸出开关 61 上， 当安全气囊 20爆开时， 拉扯拉线 66后使压框 65脱离， 微动伸出开关 61的 作动杆 62瞬间伸出， 呈现有一段时间通电状态， 如图 8、 图 9所示。
而前述微动压掣开关 55与微动伸出开关 61，两种型式结合微型电路控制开 关与连组件， 其功能藉取其体积甚小， 有利于装配； 更可以由市面贩售功能相同 的电路控制开关替代， 以求品质可靠度， 并降低成本。 撷取单元 5另一型式设计， 由感测器 70装置于安全气囊 20金属外缘上， 当 安全气囊 20爆开后， 感测器 70感测安全气囊 20爆开时的温度与震爆、 声响达 到设定一定设定范围时， 例如感测温度达设定 85 ° C、 如感测声响达设定 150dB 值， 而感测器 70能启动且呈现有一定时间通电状态， 如图 8、 图 9所示； 如此 设计， 搭配用于防止车辆发生火灾的预防装置， 可解决遭纵火、 无故着火、 恐怖 攻击等车辆着火事故； 而配置多颗安全气囊 20的车辆， 当车辆出现不同部位撞 击时， 引爆相对应部位安全气囊 20， 同时由爆开安全气囊 20的撷取单元 5， 连 线外接式装置 30， 如用于防止车辆发生火灾的预防装置， 对引擎、 油箱、 电动 车的电力发动机、 电瓶处进行灭火， 如图 13所示。 基于外加式装置在使用时可 靠度需求， 可将前述压掣元件 50与拉扯元件 60， 以混合搭配使用， 如图 10及 图 11所示， 能获到确实作动的效果； 由于交通事故发生， 宜于短时间内抢救， 车辆上的卫星导航器材 （GPS ) 与 （3G ) 通讯、 视讯器材 （CCD ) 藉一装置整合三 者器材功能， 设定自动发话、 报案等功能的设计， 当安全气囊 20爆开时， 撷取 单元 5能使前述装置发挥功效而通讯报案外， 并藉卫星导航器材 （GPS ) ， 寻找 事故地点， 救援单位能藉视讯器材 （CCD ) 器材， 检视客舱内乘员受困情形。
藉此， 透过撷取单元 5的设计， 当车祸发生安全气囊 20爆开时， 可同撷取 安全气囊 20爆开的讯号， 使外接式装置 30发挥功效， 自可组构成同步且作动确 实的车辆安全气囊讯号撷取系统， 适用于现有使用中车辆， 而另外电子控制单元 ( ECU) 10， 针对前述车辆安全防护的缺口， 在现有电子控制单元 （ECU) 10 设 计系统， 将输出讯号电路中， 扩大输出讯号功能， 加植线路， 除连线安全气囊 20外， 并连线外接式装置 30， 纳入重新开发新型式电子控制单元 （ECU) 10系 统中， 期盼不久将来， 能将新型式电子控制单元（ECU ) 10与外加式装置 30， 列 为标准配备，装置于新型式车辆上，除填补前述缺口外，更能符合时代潮流需求。
