Description

座椅调节开关
技术领域
本发明涉及一种座椅调节开关,所述座椅调节开关具有通过感应栓杆操作的并布置在共同的支撑板上的多个多路力传感器,其中至少一个按钮罩作为操作元件与感应栓杆连接。
背景技术
座椅调节开关通常具有多个可以用于控制各种功能的开关元件。这些开关元件中的至少一个操作元件通常以风格化的座椅轮廓的形式形成。座椅轮廓可以被设计为离散块或整体。风格化的座椅轮廓可以用于控制至少一些功能头枕向上/向下和向前/向后、座椅靠背向前/向后以及座垫前部向上/向下、后部向上/向下和向前/向后。
与过去常见的座椅调节开关相比,现代座椅调节开关优选地使用具有一个或多个开关阀值的力传感器。力传感器通常设计为在机械上非常坚固的。
根据德国专利申请DE 10 2015 014 878A1已知了一种具有力传感器系统的通用座椅调节开关。该文件具体描述了一种用于调节机动车辆座椅的操作装置。开关罩布置在操作装置的基体上,所述开关罩围绕至少一个旋转轴旋转并沿着至少一个方向平移。至少一个检测装置通过确定作用在开关罩上操作力的大小和方向来检测开关罩的位移。根据该操作力,车辆的座椅是可以调节的。
根据德国专利申请DE 10 2014 014 021A1已知了一种电容式多路力传感器形式的检测装置的简单并且有利的实施例,该申请的全部内容在此通过引用结合到本文件中。
DE 10 2014 014 021A1中描述的多路力传感器具有栓杆状的操纵杆,该操作杆与壳体的上部刚性连接。在壳体内部,操作杆与金属或金属化板连接。当操作杆转动时,极板同时相对于电路板上的金属或金属化表面转动,从而使由极板和表面排列形成的电容器的电容值随着操作杆的转动而变化。由于壳体的上部必须同时发生弹性变形才能使操作杆转动,因此多路力传感器相当坚硬的,非常适合应用于座椅调节开关。为了实现特别坚固的设计,操作杆和壳体的上部都可以由金属制成。
要实现座椅调整开关,开关罩,即由用户操作的操作元件,必须连接到至少一个多路力传感器。
缺点是,特别是在由金属制成的多路力传感器的情况下,需要进行昂贵的后处理,以实现用于连接按钮罩的合适形状,例如弹簧夹头、导向面或底切。通常,这里使用的几何形状是通过简单的车削过程或通过滚轧加工而成。铣削工艺也偶尔被使用。多路力传感器的金属栓杆具有滚花、锯齿状轮廓或配合弹簧。
形状接合的建立通常只在一定的条件下是可能的,因此按钮罩的紧固通常是摩擦性的。发现以这种方式创建的连接通常不满足所有公差位置和温度范围内的拉力和扭力的要求。
发明内容
本发明的目的是建立一个通用的座椅调整开关,使按钮罩可以以特别简单和经济高效的方式与感应栓杆进行特别稳定的连接。
根据本发明,该目的通过以下方式实现:感应栓杆穿过接收套筒,所述接收套筒与支撑板制成一体并通过柔性区域与支撑板的其他部分连接,并且连接到感应栓杆的至少一个的按钮罩与接收套筒形成形状接合。
附图说明
下面本发明的示例性实施例将参考附图示出和解释。
附图中:
图1座椅调整开关的剖面图,
图2以单独的图示显示了支撑板,以及
图3以单独的图示显示了传感元件。
在图1中示出了一个组装的座椅调节开关沿着具有附加的按钮罩3的多路力传感器1的剖面。
具体实施方式
多路力传感器1按照电容测量原理起作用并且由布置在一块支撑板4上的一个金属传感元件9和一块在其上获得导体结构(这里未示出)的印刷电路板8组成。
传感元件在图3中作为单个部件示出的传感元件9具有基本上圆筒形的感应栓杆2。金属或金属化的感应板7与感应栓杆2的下端部连接,当感应栓杆2绕其纵向轴线转动时,所述感应板也发生转动。
这改变了感应板7相对于布置在印刷电路板8上的导体结构的位置。感应板7与单个的导体结构形成电容器,他们的电容值随感应板7转动发生变化。电容的变化可以通过电子设备(在此处也未示出)进行评估,以确定感应板7的位置变化,从而确定作用在感应栓杆2上的操作力。感应栓杆2的转动通过附接的按钮罩3实现。
这里的座椅调节开关例如总共具有五个这样的多路力传感器1,它们能够连接到多个单个的按钮罩3或者一个共同的按钮罩3。
提供一块支撑板4,用于布置和固定传感元件9并且实现至少一个按钮罩3与传感元件9的金属感应栓杆2之间的稳定耦合。
支撑板4作为单个组件在图2中示出。此处作为单个组件示出的支撑板4也可以可选地集成到现有的壳体中。
图2中所示的支撑板4设计为一个用合成材料注塑成型的平面板,在该平面板上一体地形成多个接收套筒5,这里根据所提供的传感器的数量是五个。接收套筒5的纵轴线与板平面垂直对齐。围绕接收套筒5的多个旋紧开口11是可识别的。定心销12也围绕接收套筒5布置,从支撑板4的下侧垂直突出。
图3中示出了单个传感元件9。传感元件9由原先为正方形或矩形的金属板构成,从该金属板沿其对角线方向切割出带状的旋紧连接板13和定心臂15。这些旋紧连接板13和定心臂15的端部构造成旋紧孔眼14和定心孔眼16。定心孔眼16设计为长孔和孔的组合,目的是将传感元件9于支撑板4定中心。
与旋紧连接板13和定心臂15一体地连接的金属板的部分因此构造成近似三叶草形的感应板7,垂直突出的圆筒形感应栓杆2牢固地连接到其中心。
在组装座椅调节开关后,多个传感元件9布置在图2所示的支撑板4的下侧,其中其感应栓杆2插入到接收套筒5中并且具有旋紧孔眼14的旋紧连接板13通过螺栓与支撑板4中的旋紧开口11连接。为了精确定位,在支撑板4下侧布置的定心销12插入传感元件9的定心孔眼16中。
从图1中可以看出,多路力传感器1的感应栓杆2各自穿过接收套筒5,使得接收套筒5各自同心地围绕感应栓杆2的部分长度。
为了使感应栓杆2能够可转动,支撑板4在各个接收套筒5周围形成周向的柔性区域6,其具有曲折或波纹管的形状,同时大大地减小壁厚。此外,该实施例具有保护多路力传感器1免受湿气和灰尘影响的优点,因为接收套筒5和支撑板4的其他区域之间的周向的柔性区域6各自形成封闭表面。
在支撑板4的制造中的优点在于,由于这些变薄的柔性区域6的大面积连接,仍提供足够的横截面在注塑过程中填充接收套筒5的内部区域,而无需预留单独的注射点。
在图1中还可以看出,感应栓杆2的自由端部段插入按钮罩3中并且被在按钮罩3中成型的内壁包围。按钮罩3的外壁插入接收套筒5的上部扩展的部分。
为此,接收套筒5被设计为使其与至少一个按钮罩3形成形状接合的连接并且能够接收施加到按钮罩3上的拉力和扭矩。为了建立形状接合,接收套筒5可以具有例如如图2中所示成型的凹槽10。在这些凹槽10中,可以使用在按钮罩3上成型的凸条。
一方面,由于在至少一个按钮罩3和接收套筒5之间存在形状接合的连接,并且感应栓杆2分别被接收套筒5和至少一个按钮罩3包围,因此不需要感应栓杆2与至少一个按钮罩3之间附加的摩擦连接或形状接合连接。
因此,如图3中特别清楚地示出的感应栓杆2能够各自构造为简单的圆筒形金属销。因此,可以有利地节省用于在感应栓杆2的端部成形连接结构的复杂的再加工。
