具体实施方式
以下将结合附图描述根据本发明的方向盘组件的具体实施方式。下面的详细描述和附图用于示例性地说明本发明的原理，本发明不限于所描述的优选实施例，本发明描述的各个实施例既可以单独使用，也可以任意组合，本发明的保护范围由权利要求书限定。
此外，空间相关术语(诸如“上”、“下”、“左”和“右”等)用于描述附图所示的元件与另一个元件的相对位置关系。因此，空间相关术语可以应用到使用时与附图所示的方向不同的方向中。显然，虽然为了易于说明，所有这些空间相关术语指的是附图所示的方向，但是本领域技术人员能够理解可以使用与附图中所示的方向不同的方向。
图1示出根据本发明实施例的方向盘组件的立体图。图2示出根据本发明实施例的方向盘组件的分解图。以下结合图1和图2描述根据本发明实施例的方向盘组件。
如图1和图2所示，本发明提供的方向盘组件1包括方向盘10、传动构件20和电子装置30。方向盘10包括方向盘轮缘11和方向盘中心部12，并且，方向盘轮缘11围绕方向盘中心部12布置。一般地，方向盘10还包括大致在其径向方向上延伸的多个辐射状构件，以连接方向盘轮缘11和方向盘中心部12。能够从图2中观察到，在本实施例中示出了两个辐射状构件，当然，这仅仅是示例，本发明的方向盘组件可以根据实际需求设置其他数量的辐射状构件。
传动构件20被构造为在方向盘10和转向柱(未示出)之间传递转矩，例如，在方向盘10的方向盘中心部12和转向柱之间传递转矩，从而将驾驶员施加在方向盘10上的转矩传递到转向柱，以执行车辆的转向操作。图2中示出的传动构件20包括法兰凸缘，支架21上的螺栓穿过该法兰凸缘上的通孔并且经由螺母300将两者固定到一起，并且之后将被固定到车辆上的预定位置处。
此外，如图2所示，本发明的方向盘组件1还包括电器元件14，在一个实施例中，电器元件14被构造为环状以与方向盘骨架13的环状部的形状适配从而快速地包覆在该环状部上，以及由此被设置在方向盘轮缘12处。当然，设置在方向盘轮缘12处的电器元件14在方向盘10旋转时将与其一起旋转。以及，电子装置30设置在方向盘中心部12处。在本发明的方向盘组件1中，电子装置30被设置为在方向盘10旋转时保持静止，这意味着，电子装置30设置在方向盘中心部12处的同时相对于方向盘始终保持为在运动方面彼此分离的部件，从而确保电子装置30不受方向盘旋转的影响，这将在下文进行更详细地描述。
同样地在图2中，还示出了本发明的方向盘组件1所包括的时钟弹簧单元40，该时钟弹簧单元40被设置在电子装置30的下方。换言之，在方向盘10的轴向上，电子装置30和时钟弹簧单元40被上下叠置，例如，时钟弹簧单元40可以位于电子装置30和传动构件20之间，以在电器元件14、电子装置30分别与车辆之间提供信号传输。
图3示出根据本发明实施例的方向盘组件中时钟弹簧单元的示意图。图4示出根据本发明实施例的方向盘组件的剖视图。以下结合图2、图3和图4详细描述示例性的时钟弹簧单元40。
如图2所示，时钟弹簧单元40包括用于安装时钟弹簧的第一骨架41，该第一骨架41大致为锥状并且经由螺栓400固定到传动构件20的支架21(其始终保持静止并且被螺母300固定到传动构件20的法兰凸缘上)上，并且具体地，第一骨架41包括基座411和从基座411突出的柱状部412。以及，如图3所示，时钟弹簧单元40包括连接到电子装置30的第一连接端40A、连接到电器元件14的第二连接端40B、连接到车辆的第三连接端 40C，其中，第一连接端40A从图3中所示的时钟弹簧单元40的正面穿过通孔到达时钟弹簧单元40的背面，因此，其仅部分可见。而且，时钟弹簧单元40包括内时钟弹簧部分42和围绕其的外时钟弹簧部分43，两个时钟弹簧部分之间允许发生相对转动，并且具体地为外时钟弹簧部分能够相对于内时钟弹簧部分发生相对于转动。内时钟弹簧部分42上设置有以上提到的、供柱状部穿过的通孔以及从该通孔穿过的第一连接端40A。第三连接端40C在本实施例中也设置在了内时钟弹簧部分42上，当然，这仅仅是示例性的，第三连接端可以设置为多个，例如，分别为每个第一连接端以及每个连接端设置一个专用的第三连接端。与此同时，外时钟弹簧部分43上设置有第二连接端40B，在本实施例中，外时钟弹簧部分43上设置有两个第二连接端40B，其两者以一左一右布置的方式在图3中的外时钟弹簧部分43上示出，例如，电器元件14包括用于离手检测的第一电器元件和用于方向盘加热的第二电器元件，相应地两个第二连接端40B分别用于离手检测和方向盘加热两个功能的信号传输。当然这仅仅是示例，电器元件还可以包括心率检测、振动马达、照明、按键等其他类型的元件。
在本发明中，外时钟弹簧部分43被设置为在方向盘10旋转时与其一起旋转，以及，内时钟弹簧部分42被设置为与第一骨架41固定在一起并且由此在方向盘10旋转时保持静止。
以下分别描述内时钟弹簧部分和外时钟弹簧部分的固定。
内时钟弹簧部分42上的如上所述的通孔作为容纳部，以供第一骨架41的柱状部412穿过并且之后将其的至少一部分容纳在其中。而且，内时钟弹簧部分42包括面向基座411的第一侧面42A(即，图3中示为正面)，该第一侧面42A上设置有定位部421(数量示为两个)和固定部422(数量示为四个)，该定位部421用于相对于基座411定位内时钟弹簧部分42，该固定部422用于将内时钟弹簧部分42固定到基座411。能够理解，除了位于中心位置的、用于容纳第一骨架的通孔之外，时钟弹簧单元的其他位置处由于自身内部包含线束的原因而无法设置通孔，因此，上述固定结构结合定位结构将便于完成内时钟弹簧部分的便捷固定。
在一个示例中，如图3和图4所示，第一骨架41的基座411上设置有 与定位部421配合的配合定位部，并且，定位部421被构造为定位销，配合定位部被设置为与该定位销配合的定位孔，以及，固定部422凸出于内时钟弹簧部分42的第一侧面42A并且被构造为螺纹孔，该螺纹孔配合螺栓422将内时钟弹簧部分42固定到第一骨架41上，并且其设置在凸出于第一侧面42A的突伸部内。当然，本发明的方向盘组件不限于上述示例，例如，图6(a)、图6(b)示出了替换实施例，在图6(a)中，定位部被构造为定位孔，配合定位部413被设置为定位销；在图6(b)中，定位部421被构造为定位销，配合定位部被设置为定位孔，以及，固定部422相对于内时钟弹簧部分的第一侧面凹入并且被构造为螺纹孔。
在一个示例中，如图3和图4所示，方向盘骨架13和外时钟弹簧部分43之间设置有转矩传递部，以用于在两者之间传递转矩，具体地，转矩传递部包括转矩传递孔431和插入转矩传递孔431中的转矩传递销，转矩传递销被设置在方向盘骨架13上，转矩传递孔431被设置在外时钟弹簧部分43上。当然，本发明的方向盘组件不限于上述示例，例如，图5(a)、图5(b)和5(c)示出了替换实施例，在图5(a)中，替换转矩传递销432被设置在外时钟弹簧部分43上，替换转矩传递孔132被设置在方向盘骨架13上；在图5(b)中，另一替换转矩传递销433被设置在外时钟弹簧部分43上并且具有膨胀端，其能够防止外时钟弹簧部分42在向上的方向上移动以脱离方向盘骨架13，另一替换转矩传递孔133被设置在方向盘骨架13上；在图5(c)中，又一替换转矩传递销434被设置在外时钟弹簧部分43上，转矩传递部还包括与上述又一替换传递销434配合的槽134，该槽被设置在方向盘骨架13 3的外缘处。当然，任何能够传递转矩的结构均可以用于本发明的外时钟弹簧部分和/或方向盘骨架上。
作为本发明的实施例，转矩传递孔和转矩传递销之间还设置有橡胶套4311，如图4所示，这可以减小转矩传递期间的噪音以及方向盘骨架和外时钟弹簧部分的磨损。
以下继续参照图1和图2描述根据本发明实施例的方向盘组件。
作为一个示例，电子装置30被构造为显示器装置，并且经由螺栓500固定在第一骨架41上，这使得显示器装置在方向盘旋转期间保持静止。 具体地，电子装置30包括安装板32，该安装板32经由螺栓500固定到第一骨架41，这在图4中示出，第一骨架41的柱状部412具有中空结构并且其内表面上设置有螺纹孔，以与螺栓500配合；电子装置30还包括显示器，显示器的底侧上设置有钩部，钩部从安装板32的上侧穿过并且经由弹簧33固定到安装板32的下侧。
此外，显示器和安装板32之间设置有减振单元50，以在使用期间减小显示器周围的振动从而保护显示器。在本实施例中，减振单元50包括设置在显示器和安装板32之间的减振主体51，并且，减振主体51上设置有相较于减振主体51更柔软的减振部52，该减振部52作为相对于减振主体51的单独部分以可拆卸的方式安装到减振主体51上，并且，多个减振部52可以根据空间或其他特殊要求设置在减振主体51的多个不同位置处。以及，减振主体51上还设置有用于限制显示器相对于安装板32的移动距离的第一止挡部53。相应地，显示器的底侧上设置有第二止挡部31，其用于限制显示器相对于安装板32的移动距离，并且，与减振部52在方向盘11的轴向上对准，以同时作为预定位部定位显示器相对于安装板的位置。
作为一个示例，如图1和图2所示，设置有固定销100，安装板上设置有固定孔，该固定销100能够穿过固定孔和方向盘中心部的孔，以在方向盘组件安装到车辆之前(例如，运输期间)固定时钟弹簧单元相对于方向盘的周向上的位置。
需要说明的是，在本发明的方向盘组件中，将时钟弹簧单元设置为内时钟弹簧部分和围绕其的外时钟弹簧部分，内时钟弹簧部分在方向盘旋转时保持静止，以及，外时钟弹簧部分在方向盘旋转时与其一起旋转，两个弹簧部分上分别设置连接端，以用于方向盘不同位置处信号传输的需求。因此，上述设置特别地允许方向盘中心部处的电子装置在方向盘旋转时保持静止、与此同时允许方向盘轮缘处的电器元件在方向盘旋转时与其一起旋转。当电子装置为显示器装置(包括但不限于此，还可以是其他同样期望不与方向盘一起旋转的电子装置)时，由于显示器装置需要在相对于车辆始终静止而不旋转的情形下提供多种功能，所以本发明的方向盘组件是 特别有益的。因此，本发明的方向盘组件能够支持将要配备到方向盘上的多种功能。
如前所述，尽管说明中已经参考附图对本发明的示例性实施例进行了说明，但是本发明不限于上述具体实施方式，本发明的保护范围应当由权利要求书及其等同含义来限定。
