Description

一种摩擦铰链及包含该摩擦铰链的车辆内部部件 技术领域
本公开涉及摩擦副，更具体地涉及一种摩擦铰链及包含该摩擦铰链的车辆内部部件。
背景技术
已知摩擦铰链总成被用来在旋转方向上提供摩擦扭矩。现有技术中的摩擦铰链总成的分件相对复杂，至少包括壳体、摩擦片和芯轴三部分，其中，壳体固定不动，一片或多片摩擦片被限位在壳体内，芯轴与旋转部件相固连并可旋转运动，运动时通过摩擦片孔的内圆与芯轴外圆摩擦提供扭矩。
显然，该已知的摩擦铰链总成的单件的加工精度要求高，例如轴芯精磨、摩擦片精冲等，总成装配难度大，例如每个摩擦片都须精确对位装配，导致总成价格高的问题。
公开内容
为了解决上述现有技术中的总成价格高等问题，本公开提供一种摩擦铰链及包含该摩擦铰链的车辆内部部件。

具体实施方式
下面结合附图，给出本公开的较佳实施例，并予以详细描述。
如图1所示，根据本公开的一个优选实施例的摩擦铰链安装在车辆V的虚线框圈出的内饰功能件产品的旋转铰链部位。如图2所示，根据本公开的摩擦铰链A被安装在副仪表板翻转扶手B上。如图3所示，根据本公开的摩擦铰链A被安装在翻转屏幕C上。应该理解，图示的应用场景及部位仅作为示例而非限制，其还可以被应用于例如翻转小桌板、旋转屏幕、座椅头枕耳片等部件，这些车辆内部部件均包括固设于车辆中的固定部件和相对于固定部件可旋转的旋转部件。
如图4-图5所示，根据本公开的一个优选实施例的摩擦铰链A包括摩擦轴1和壳体2，其中，摩擦轴1和壳体2之间通过相对运动产生摩擦力，摩擦轴1集成有芯轴和摩擦片的功能，运动时通过壳体2的孔内壁与摩擦轴1的外圆摩擦提供扭矩。在本实施例中，摩擦轴1和壳体2过盈装配。应该理解，理论上0间隙或极小间隙+油脂也是可行的。在本实施例中，壳体2固定不动，即壳体2与固定部件固连，摩擦轴1与旋转部件固连并可旋转运动。应该理解，壳体也可以“变更结构型式”后与旋转部件固连，而摩擦轴与固定部件固连。
与现有技术中独立的摩擦片相比，本公开的摩擦铰链A将摩擦片与芯轴合并为一个新零件，即摩擦轴1，总成零件数量从原有至少三个(或更多摩擦片)减少为仅有两件，并且在将摩擦轴1装配到壳体2时，摩擦轴1不需要精确对位，圆周任意角度位置均可装入，降低装配难度，使得成本更低， 更有利于批量化生产。
如图6所示，摩擦轴1包括轴端接口11和封盖12，其中，轴端接口11与旋转部件连接，封盖12固定连接在轴端接口11上。在本实施例中，轴端接口11包括圆柱两侧切平台结构。应该理解，该圆柱两侧切平台结构仅作为示例而非限制。
摩擦轴1包括悬臂结构15，其固定连接在封盖12的背向轴端接口11的端面上以提供弹性变形。实际上，该悬臂结构15形成为芯轴摩擦部，其厚度D可以根据需要进行调节，即相应调节扭矩。
在具有独立的摩擦片的现有技术中，摩擦部位为摩擦片内圆与芯轴外圆之间，需要通过变更摩擦片数量来阶梯性调整摩擦扭矩，不能做到任意扭矩的变更。本公开的摩擦铰链A的摩擦部位变更为摩擦轴1的外圆与壳体2的孔内壁之间，在制造成型过程中可通过机加工无级调整芯轴摩擦部的厚度D，在设计范围内调整到任意需要的摩擦扭矩，使翻转产品能够实现任意角度停止或缓慢关闭功能。
如图7所示，悬臂结构15在轴向上包括连接部151和悬臂部152，其中，悬臂部152通过连接部151连接于封盖12。
悬臂部152和封盖12之间限定开槽13，从而使得悬臂部152成型为弹性结构。应该理解，开槽13的尺寸可根据需要进行调整，从而提供所需的扭矩。
悬臂部152的内部形成有贯通孔14，从而使得悬臂部152成型为弹性结构。特别地，该贯通孔14通过缝隙141与外界连通，从而使得悬臂部152形成为非闭合环形结构。在本实施例中，贯通孔14并不位于悬臂部152的旋转中心，其偏心设置以使得悬臂部152的环形结构具有渐变的厚度，如图8所示。
悬臂部152的外部形成有三个摩擦凸点16，其与壳体2的孔内壁过盈装配并提供旋转摩擦扭矩，如图8所示。在本实施例中，在图示的方位下，两个摩擦凸点16左右对称地分别位于缝隙141的两侧，另一个摩擦凸点16位于缝隙141的正下方，即与缝隙141同处于悬臂部152的同一径向方向上，这种布置能够在摩擦轴1相对于壳体2正转或反转时提供相同的摩擦扭矩/摩擦力。应该理解，摩擦凸点16的具体位置和数目可以根据需要进行调整。
如图9所示，壳体2包括封口21和壳腔22，其中，壳腔22提供空腔以供摩擦轴1的悬臂结构15插入其中形成摩擦副，封口21连接固定在壳腔22的出口处以与摩擦轴1的封盖12配合形成封闭空间，从而保护其中容纳的摩擦副，防止异物进入。具体地，壳腔22的孔内壁与摩擦轴1的摩擦凸点16进行过盈配合。
图10示出了摩擦轴1的一种实施变型，其与图6至图8中所示的摩擦轴1的区别之处仅在于，对于形成于悬臂部152外部的三个摩擦凸点16，在图示的方位下，第一摩擦凸点16a和第二摩擦凸点16b左右对称地分别位于缝隙141的两侧，但第三摩擦凸点16c并非位于缝隙141的正下方，而是位于缝隙141下方更靠近第二摩擦凸点16b的位置，即第三摩擦凸点16c与缝隙141不在悬臂部152的同一径向方向上从而与第一摩擦凸点16a和第二摩擦凸点16b隔有不同距离。基于这种布置，悬臂部152的位于第一摩擦凸点16a与第三摩擦凸点16c之间的第一区段152a的长度大于悬臂部152的位于第二摩擦凸点16b与第三摩擦凸点16c之间的第二区段152b的长度。
在摩擦轴1的图示方位下，这种布置能够在摩擦轴1相对于壳体2向右旋转时提供较大的力臂，而在摩擦轴1相对于壳体2向左旋转时提供较小的力臂，即能够使得摩擦轴1相对于壳体2向右旋转时所需的力小于摩擦轴1相对于壳体2向左旋转时所需的力，因此，这种布置能够达到正转和反转提供不同的摩擦扭矩/摩擦力的效果。
此外，根据其它未示出的实施变型，无论多个摩擦凸点16采取上述何种布置方式，悬臂部152均可以形成沿其轴向的多层结构，即厚度D可以由多层形成，相邻两层之间设置有开槽，并且每一层均设置有一个或多个摩擦凸点16。
壳体2还包括安装点23和安装结构24，其中，安装点23形成在安装结构24上以使得壳体2固定不动。在本实施例中，安装点23为螺钉孔，螺钉穿过螺钉孔安装以将壳体2与固定支架安装连接。应该理解，这里的螺钉孔仅作为示例而非限制，例如铆接孔等结构也可以用在此处。在本实施例中，安装结构24为耳片，其顶触在固定支架上以防止壳体2发生转动。
显然，通过摩擦轴1的开槽13的宽度，或贯通孔14的形状，可控制悬臂结构15的变形刚度。通过摩擦凸点16的凸起尺寸可控制摩擦轴1与壳 体2的过盈量。通过变形刚度和过盈量，可控制摩擦轴1与壳体2的过盈部位的正压力，进而控制相对旋转时的摩擦扭矩。
以上所述的，仅为本公开的较佳实施例，并非用以限定本公开的范围，本公开的上述实施例还可以做出各种变化。即凡是依据本公开的权利要求书及说明书内容所作的简单、等效变化与修饰，皆落入本公开的权利要求保护范围。本公开未详尽描述的均为常规技术内容。
