Description

转动调节器
技术领域
本发明涉及一种转动调节器，其带有：固定部件（定子）的，在该固定部件上布置有电容式传感面；和能相对固定部件转动运动的部件（转子），该部件构造电容式传感面的操作面。
背景技术
具有集成电容式传感器的转动调节器原则上公知。如DE 10 2004010 406 B3介绍一种信息和娱乐***，该***具有集成有接触敏感表面的转动调节器。接触敏感的表面在此特别是可以实施为触摸屏，并且设置为手写识别的输入装置。当然，该文献在此没有公开触摸屏和转动调节器的结构构造的细节。
为在转动调节器上构造接触敏感的表面如下是适宜的，即，电的组件布置在固定部件上，特别是为了使这些元件的电的连接不限制转子的转动运动。本身的操作面可以通过转子的外表面实现，从那里出发的接触作用于定子上传感面的电的组件。
在可转动操作面下面的静立传感面处，为使干扰性摩擦影响最小化，转子的内表面与传感面之间需要一定的间距，由此产生与传感面的气隙。
接触敏感的电容式传感器的特性在很大程度上依赖于例如人的手指可以影响的操作面与本身的传感面之间的材料布置。对于精确的信号评价来说决定性的是材料特有的相对介电常数εr和材料厚度。在这种情况下，空气的相对介电常数（εr=1.0）与优选加工成转动调节器组件的（例如像转子的）热塑性塑料的相对介电常数（εr=2.5-3.5）存在很大差别。通过这种特性，转子与传感面之间存在的气隙的宽度过度地影响所检测到的电容值。
存在如下困难，即，操作面与传感面之间的相对位置和间距在扭转转子时不能得到准确保持。根据转子转动支承的精度，操作面的不同位置可能与传感面具有不同的间距，此外，该间距在转子转动时还会改变。由此电容式传感器的电的特性明显依赖于操纵位置，并且此外，在转动操纵时也不恒定。
发明内容
目的在于，提供一种转动调节器，其中尽可能消除由旋转的操作面与静立的电容式传感面之间变化的间距造成的传感误差。
该目的依据本发明由以下方式得以实现，即，操作面与传感面之间布置有至少一个进行间距固定的机构，以及弹簧元件将传感面压向操作面的方向。
依据本发明因此采取的措施是，操作面与传感面之间存在的间距首先尽可能小地、并且其次在其延展中尽可能恒定地保持。
优选地，进行间距固定的机构可以实施为抗扭地受支承的滑盘，该滑盘几乎完全填满操作面与传感面之间的间隙。滑盘的材料和表面构造如此的选择，使得转子的底面尽可能低摩擦地沿滑盘之上运动，并且此外，滑盘具有与转子材料和定子材料尽可能良好匹配的介电常数。
作为滑盘的备选方案，传感面上或操作面上也可以设置有成型的销子或凸起部，它们作为隔离支架与操作面或传感面配合作用。隔离支架同样满足如下目的，即，预先给定定子部件与转子部件之间恒定的和尽可能小的间距。出现的摩擦力可以通过隔离支架的适当表面构造很低地保持。
任何情况下都设置有弹簧元件，该弹簧元件将传感面压向转子的方向，从而一个或多个进行间距固定的机构紧密包围在传感面与转子的底面之间。
特别有利的是，弹簧元件是电的开关的组成部分。这种布置除了平衡转子的摆动外，同时还可以在保持恒定气隙的情况下构造转动调节器的压力开关功能。
附图说明
附图示出本发明的实施例并在下面借助附图进行详细说明。其中：
图1示出转动调节器的示意剖面图；
图2示出另一转动调节器的示意剖面图；
图3示出一种转动调节器实际构造的剖面图。
具体实施方式
图1和2分别以剖面图示出依据本发明的转动调节器的示意结构。转动调节器由静立地布置的、***形构造的定子3组成，围绕该定子周围布置有转子4。转子4作为空心圆柱式的转轮构造，该转轮可转动地支承在转动调节器的静立的外壳部件8上。
承载传感面2的支撑板6通过弹簧元件7与定子3连接。这里仅示意地示出的传感面2优选通过平面延伸的导体结构形成，该平面延伸的导体结构与未示出的电子处理装置电地连接。导体结构构造一个电容器***，该***通过电容变化可以位置解析地评价物体的、在由转子4表面构造的操作面1处的接近。
为达到，转子4相对传感面2可以无干扰性摩擦地转动，传感面2与转子4的底面具有间距地布置。为可以使该间距能尽可能少地干扰性地影响电容测量，需要间距首先尽可能小，并且其次在整个传感面2上尽可能恒定，并且第三在转子4转动时尽可能少地变化。
为满足这些条件，设置有至少一个进行间距固定的机构（5'、5″），该机构将传感面2与转子4之间的间距尽可能小地和恒定地保持。
图2示出作为进行间距固定的机构在传感面2上或在转子4的底面上成型的多个隔离支架5″。该隔离支架5″具有销子或局部凸起部的形状。隔离支架5″的形状和表面如此地构造，使得能运动地贴靠的面，也就是转子4的底面或传感面2可以尽可能低摩擦地沿隔离支架5″滑动。隔离支架5″的垂直延展在图2中比例上强烈夸张地示出，从而产生的气隙9在实际布置中比这里所示可能窄得多，并且因此对转动调节器的导电特性只有少许的影响。特别有利的是，气隙9不仅很窄，而且在操纵转动调节器时，也就是在相对定子3转动转子4时以较高的精度保持恒定，这是因为通过弹簧元件7的压紧力，传感面2始终紧密贴靠在隔离支架5″上。
图1示出传感面2与转子4的底面之间的滑盘5′作为进行间距固定的机构。滑盘5′优选实施为具有尽可能光滑且低摩擦的表面的、柔软的塑料盘或塑料膜，必要的话该表面可以额外地利用润滑材料覆层。滑盘5′优选填满传感面2与转子4底面之间的整个间隙，从而使得滑盘5′与传感面2之间的、或与转子4的底面之间的气隙可以忽略。滑盘5′的材料的介电常数有与组成转子4的材料类似的数值。滑盘5′优选只有少许可压缩性，从而使得该滑盘不会由于转子4相对于定子3可能出现的摆动发生值得一提的收缩。
图3示出转动调节器的一种真实设计方案的剖视图。转动调节器布置在操作孔板11的内部，并利用其底面直立在优选通过电路板形成的基面12上。压力开关10与电路板电地连接，其开关杆13可以逆着弹簧元件7′的复位力操纵。
转动调节器定子3的***形区段14贴靠在开关杆13上。经由***形段14和开关杆13，弹簧元件7′的力作用于定子3，并且将水平定向的支撑板6压向滑盘5′，该滑盘由此又紧密贴靠在罩式转子4的底面上。弹簧元件7′的力导致，在转动操纵转子4时，承载电的传感器的定子3与转子4之间几乎不出现间隙。由此在接触操作面1时，电的特性几乎不依赖于操纵位置，而且在扭转转子4时也不改变。
通过压力开关10完成压力开关功能，该压力开关功能可以通过在操作面1上的按压操纵触发。按压操纵例如可以设置用于操纵地触发此前通过接触操作面1选取的开关功能。因为即使在按压操纵时，转子3与定子4之间的间距也不变，所以压力开关功能对电容式传感器的质量绝对没有不利影响。
