Description

一种安全带辅助佩戴装置 技术领域
本发明涉及汽车安全设备领域，具体涉及一种安全带辅助佩戴装置。
 背景技术
传统安全带锁舌的起始位置一般位于安全带导向环和安全带下固定点之间。这种安全带的主要缺点在于：锁舌在起始位置时处于悬空状态，当车辆转弯或者颠簸时，锁舌容易撞击内饰板（材料一般为塑料）或周边零件，发出噪音；除此之外，对于身材较小的乘客，当其将座椅向前滑动到其舒适位置时，安全带锁舌通常离其身体较远，其佩戴安全带锁舌时需要向后大幅度扭转身体才能够拿取锁舌，实现佩戴功能，操作便利性较差。

 本发明的实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
请参图1-3，本发明提供一种安全带辅助佩戴装置，包括锁舌1、锁头2、伸缩机构4、吸附件5、第二传动件6、第一传动件7、动力源8。
其中，伸缩机构4安装在汽车的座椅3上，吸附件5内嵌于伸缩机构4远离座椅3的一端，第二传动件6、第一传动件7、动力源8均内嵌于座椅3内部。
锁头2内部安装有第一传感器，座椅3内部安装有第二传感器和控制模块，锁头2内的第一传感器用于感测锁舌1当下是处于锁止状态还是解锁状态，并将锁舌1的状态信号传送给座椅3内部的控制模块，座椅3的第二传感器用于感测目前是否有乘客坐在座椅3上，并将感测到的信号传送给控制模块。具体地，第一传感器可以是接近传感器，其在感测到锁舌1插入锁头2内时向控制模块发送锁止信号，在感测到锁舌1远离锁头2时向控制模块发送解锁信号。第二传感器可以是重力传感器，其在感测到座椅3上的重量超过设定的重量阈值时，向控制模块发送载客信号，表明座椅3上有乘客存在，并在感测不到座椅3上有重量或者座椅3上的重量没有超过重量阈值时，向控制模块发送空载信号，表明座椅3上没有乘客存在。在本实施例中，控制模块设于座椅3内部，可以理解地，控制模块也可以设置在其它位置，只要使第一传感器和第二传感器与控制模块信号连接即可。
伸缩机构4安装在座椅3的靠近安全带的靠背侧翼9上，位于距坐垫10 40cm的高度处，该高度位置的设计能够让乘客更加方便地拿取锁舌1。进一步的地，伸缩机构4包括一可伸缩的矩形壳体，该壳体的外端封闭，内端开口，且该壳体包括若干段相互套设在一起的子壳体，这些子壳体的横截面尺寸（包括长度和宽度）由壳体的外端向壳体的内端逐渐增加，即，越靠近壳体外端的子壳体的长度和宽度越小，越靠近壳体内端的子壳体的长度和宽度越大。另外，这些子壳体的尺寸设置使得相邻子壳体之间的连接不易因外部拉力而断开。如此，使得这些子壳体可在伸缩机构4内部的伸缩驱动机构11的驱动下向外移动，使壳体伸长，或向内收缩，使壳体缩短。吸附件5设于靠近壳体外端的子壳体上，本实施例的吸附件5为磁体。第二传动件6安装在伸缩机构4壳体的开口端和第一传动件7之间。伸缩驱动机构11位于伸缩机构4的壳体内，其外端与伸缩机构4的壳体连接，其内端的一侧与第二传动件6相连接。本实施例中的伸缩驱动机构11为四连杆机构，其包括多组枢接在一起的连杆，每组连杆的中部交叉且枢转连接，且每组连杆的端部与相邻组的连杆枢接，最外侧的连杆的外端与最外端的子壳体枢接，最内侧的其中一根连杆的内端与第二传动件6枢转连接。本实施例中的第二传动件6为直齿条，第一传动件7为与直齿条配合的齿轮，动力源8为与第一传动件7连接的电机。动力源8与第一传动件7连接，能够驱动第一传动件7带动第二传动件6水平运动，进而带动伸缩驱动机构11垂直运动，实现伸缩机构4的伸缩。
在本实施例中，在乘客未坐上座椅前，锁舌1吸附在吸附件5上，当乘客坐在座椅3上时，位于座椅3上的第二传感器将载客信号传给位于座椅3内部的控制模块，然后，控制模块向动力源8发送驱动信号，驱动动力源8带动第一传动件7沿第一方向转动，带动第二传动件6水平运动，使伸缩驱动机构11在第二传动件6的带动下向外垂直运动，吸附件5向外伸出，将吸附的锁舌1推送至乘客面前。
当乘客坐好后，将安全带锁舌1插入锁头2中，锁头2内部的第一传感器感测到安全带锁舌1，将锁止信号传送给控制模块，控制模块向动力源8发出反向运转信号，驱动动力源8带动第一传动件7反向转动，第一传动件7带动第二传动件6反向水平运动，第二传动件6带动伸缩驱动机构11垂直向内收缩，使吸附件5和伸缩机构4缩回。
当乘客将锁舌1从锁头2中取出时，锁舌1在安全带卷收器作用下回收，当经过座椅3侧翼位置时，锁舌1被吸附件5吸附在伸缩机构4上，便于乘客下次拿取，同时避免了在不使用安全带时锁舌1触碰车体其他结构而产生异响。
经过上面的叙述可以知道，本发明提供的安全带辅助佩戴装置，在身材较小的乘客将座椅向前滑动至其舒服的位置后，伸缩机构能够将安全带锁舌送至方便乘客拿取的位置，不需要扭转身体抓取锁舌，佩戴方便；同时，伸缩机构伸出后，能更直接地提醒乘客在车辆启动前佩戴安全带；另外，在安全带不使用时，吸附件能够吸附安全带锁舌，避免在车辆行驶过程中，因锁舌的晃动而产生的异响。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
