Description

车辆安全防撞装置 技术领域
本发明涉及一种应用于车辆上的安全防撞装置， 尤其涉及一种应用 于摩托车或电动车上的防撞装置。 背景技术
由于驾驶摩托车或两轮电驱动车辆安全系数较低， 在摩托车或两轮电 驱动车辆上加装牢固的保险杠是保障安全驾驶的一项重要措施。 但国内并 没有摩托车或两轮电驱动车辆保险杠的相关标准， 而目前市场上也很少有 在车辆上积极设置相关安全保险设施的生产厂家。 一般摩托车生产厂家很 少在整车上设计美观牢固的保险杠， 有的甚至连安装保险杠的位置都未留 出； 而两轮电驱动车辆生产厂家一般只在车身塑料覆盖件整体外观设计过 程中， 附带考虑到起保险杠作用的覆盖件， 且仅仅局限在美观的外表而忽 视覆盖件的整体牢固程度。
而这些现有的保险杠大部分也是针对摩托车或两轮电驱动车辆侧翻和 碰擦时起到一定的保护作用的设计。 例如， 市场现有摩托车大部分保险杠 都是双侧护保险杠， 一般固定在驾驶人膝盖前方的车架上， 向外支伸， 相 当一部分都是消费者自主安装， 一般使用电焊的办法固定在车架上， 这样 摩托车一旦倒地， 首先是保险杠与路面接触， 人身特别是膝盖部位将受到 保护。 而市场上两轮电驱动车辆一般是在车身覆盖件边缘加装一条金属弯 管在碰撞或碰擦中主要起到保护覆盖件的作用， 对于驾驶者并没有起到有 效的保护作用。
而在事故统计中， 相当一部分事故也是摩托车或两轮电驱动车辆正面 确 认 本 碰撞或是先发生了正面碰撞后又发生了车辆侧翻。 摩托车或两轮电驱动车 辆正面碰撞时如果没有緩冲吸能作用进行保护， 碰撞的巨大能量必然会首 先对车轮产生作用， 使车前轮扭曲变形， 破坏车的转向系统和车架， 进而 威胁到驾驶人的安全。 而针对先发生了正面碰撞后又发生了车辆侧翻的情 况， 如果能吸收一部分正面碰撞的能量， 侧翻时候对车辆和人体的损伤也 会相应的有所降低。 由此可见， 针对摩托车或两轮电驱动车辆有效的防撞 保险装置， 尤其是正面碰撞的情况， 目前还存在有很多空白。
鉴于上述问题，有必要提供一种新的安全防撞装置来解决上述不足。
发明内容
