Description

一种灵敏度高、便于安装、成本低的汽车防夹条 技术领域
本发明涉及汽车防夹技术领域，具体地说，是一种灵敏度高、便于安装、成本低的汽车防夹条。
背景技术
在现有的车门防夹系统中主要有如下几种方式：通过传感器、生命检测仪器、机械结构检测车门是否夹到物体或人，并将检测结果反馈到单片机由它控制车门再度打开，以实现安全防护的作用。现有的设计都存在以下缺陷：车门关闭后的启动过程中，或在行车中关闭车门时，如乘客是在车门外且身体或衣物被车门夹住，将马上摔倒并卷入车底，并有可能造成身亡。由于现有的设备无法满足安全防护的需求，因此时常发生乘客的背包或身体被车门夹住，而后被卷入车底最终付出生命代价的事件，而发生这些事件的最大原因与车门防夹功能不完善有关。
为了达到防止夹伤乘客的要求，通常会在车门设置防夹条，直接获知车门关闭时是否有障碍状态，以减少对乘客的伤害。现有的防夹条通过金属骨架安装到金属支架上，金属支架再通过螺钉紧固到车门钣金上，在防夹条的橡胶体内设置包括正负导线的防夹检测结构。当车门在关闭的过程中碰到障碍时，正、负导线受到挤压发生接触，形成电路回路短路电阻，防夹模块检测到此信号后，发出警报或控制车门方向运动。
现有技术公开了多种汽车防夹条，例如中国专利2017209522646和2017106492944公开了一种汽车防夹条，设有防夹条、固定支架、密封固定装置、导线、导线接口、防夹控制器，所述的防夹条设有第一导线、第二导线、导电体、绝缘体、装配部件、电阻。中国专利2016212745005公开了一种汽车防夹条，设有第一导线、第二导线、导电体、绝缘体、骨架、固定支架、电阻以及防夹控制模块；所述电阻设置在防夹条的端部；所述电阻两端分别与第一导线、第二导线的一端相连；所述第一导线与第二导线另一端与防夹控制模块连接；所述防夹控制模块设置在防夹条另一端部；所述第一导线与第二导线设置在导电体内部；所述骨架设置在导电体下部；所述绝缘体包裹在骨架与导电体的表面；所述固定支架设置在绝缘体外侧。中国专利2016207864593公开了一种新型汽车防夹条，包括防夹条、固定支架、密封固定盖、导线、导线插口和胶带，导线的两端分别连接防夹条内部的导电材料和导线插口，密封固定盖为中间有通孔的环形结构，其中间孔穿过导线后，安装在需穿过导线的车身或车门钣金件孔上。现有的防夹条存在如下 缺点：(1)防夹模块通过正负导线及导电材料压迫接触的方式进行检测，由于使用惯性，防夹障碍部位容易集中在防夹条特定部位，如果经常发生压迫触碰容易导致接触部位磨损或氧化，造成灵敏度下降甚至失灵；(2)通过固定件或紧固螺钉的方式进行固定，防夹条零件数量多、重量大，安装工序繁琐，浪费材料及人工时间，成本高，且不美观。因此针对现有技术的缺点，有必要研发一种灵敏度高、便于安装、成本低的汽车防夹条。
发明内容
本发明的第一个目的是针对现有技术中的不足，提供一种灵敏度高、便于安装、成本低的汽车防夹条。
为实现上述第一个目的，本发明采取的技术方案是：

2、现有技术的防夹条通过压迫接触的方式进行防夹检测，这种检测结构存在灵敏性差和误动作率高的问题，由于使用惯性，防夹条的误夹障碍部位容易集中在特定部位(例如车门右下角)，如果在该部位经常发生误夹障碍压迫，容易导致防夹条内导电体接触部位磨损或氧化，造成灵敏度下降甚至失灵。本发明在连接导线与防夹条本体的连接处设置压力传感器，在绝缘橡胶体的上端内部设置气囊体，在气囊体末端对应于压力传感器的位置设置喷嘴，气囊体受挤压变形产生压力报警信号，通过压力报警信号和电阻报警信号同时报警，提高防夹条检测灵敏度。采用本实施例的结构，可以提高防夹模块的检测灵敏度，避免由于导电体接触部位磨损或氧化造成的灵敏度下降甚至失灵，提高防夹条的使用安全性。

本实施例的汽车防夹条的使用方法：将装配好的汽车防夹条通过金属骨架装配在汽车侧门或尾门边缘，将防夹控制器通过传输模块与汽车中控进行连接。当汽车尾门或侧门夹到障碍物时，障碍物首先会将气囊体挤压变形，气囊体内的空气从喷嘴喷出形成气流，该气流对压力传感器施加压力，压力传感器受到压力后产生压力信号，压力传感器将此压力信号传递给防夹控制器的处理器，处理器根据受到的压力值变化发出信号，通过传输模块传输至汽车中控，并通过报警模块进行压力报警。当障碍物进一步施压使绝缘橡胶体内的导电体挤压靠近直至接触，形成电路回路，从而短路电阻，防夹控制器的处理器根据接收到的电阻值变化发出信号，通过传输模块传输至汽车中控，并通过报警模块进行电阻报警。汽车中控可根据接收到的不同报警信号进行智能化处理，当汽车中控同时接收到压力报警信号和电阻报警信号时，汽车中控控制汽车尾门或侧门，使其停止运行，起到防夹控制功能。当汽车中控只接收到单独一种报警信号时，汽车中控语音提示司机人工检查车门是否夹到障碍物。
现有技术的防夹条通过压迫接触的方式进行防夹检测，这种检测结构存在灵敏性差和误动作率高的问题，由于使用惯性，防夹条的误夹障碍部位容易集中在特定部位(例如车门右下角)，如果在该部位经常发生误夹障碍压迫，容易导致防夹条内导电体接触部位磨损或氧化，造成灵敏度下降甚至失灵。本实施例在连接导线与防夹条本体的连接处设置压力传感器，在绝缘橡胶体的上端内部设置气囊体，在气囊体末端对应于压力传感 器的位置设置喷嘴，气囊体受挤压变形产生压力报警信号，通过压力报警信号和电阻报警信号同时报警，提高防夹条检测灵敏度。采用本实施例的结构，可以提高防夹模块的检测灵敏度，避免由于导电体接触部位磨损或氧化造成的灵敏度下降甚至失灵，提高防夹条的使用安全性。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明方法的前提下，还可以做出若干改进和补充，这些改进和补充也应视为本发明的保护范围。
