作为本公开的一个方面，提供一种阻尼装置，其中，如图1和图2所示，所述阻尼装置包括壳体110、导向滚轮120、摩擦筒130和缓冲轴(参见图3中的附图标记150)。如图3和图4中所示，缓冲轴150包括轴本体151和缓冲件152。
缓冲件152的安装部相对于摩擦筒130固定地设置在壳体110内，轴本体151的一端与缓冲件152相连。
轴本体151的另一端设置在壳体110的底板上，导向滚轮120可旋转地设置在轴本体151上。
摩擦筒130套设在导向滚轮120外部，并与壳体110分离，导向滚轮120的外径小于摩擦筒130的内部尺寸，以使得摩擦筒130的内表面与导向滚轮120的外表面之间存在间隔。
壳体110的侧壁112上设置有第一导线入孔112a和第一导线出孔112b，摩擦筒130上设有第二导线入孔130a和第二导线出孔130b，第一导线出孔112b能够在第一导线入孔112a与第二导线入孔130a相对时与第二导线出孔130b相对。
本公开所提供的阻尼装置与室外设备(例如，CPE)配合使用，其中，所述室外设备设置在室外，本公开所提供的阻尼装置设置在室内。在安装时，室外设备的导线200的一端通过壳体110的第一导线入孔112a进入壳体110内部，随后导线200的一端通过摩擦筒130上的第二导线入孔130a进入摩擦筒130和导向滚轮120之间的间隔。导线在摩擦筒130和导向滚轮120之间的间隔绕过导向滚轮120并从摩擦筒130上的第二导线出孔130b穿出，最终导线通过壳体110的侧壁112上的第一导线出孔112b从阻尼装置中穿出，并与室内的电子设备相连，这就使得在初始状态下，摩擦筒130被导线200悬挂在壳体110内。
当所述室外设备固定在相应的安装基础上时，如图3所示，所述阻尼装置中，摩擦筒130在导线200的作用下，在所述阻尼装置的壳体110内悬空，并且导向滚轮120与摩擦筒130之间无接触。当以较慢的速度抽拉导线200时，导向滚轮120可以绕所述轴本体旋转，从而可以完成阻尼装置与室外设备的导线进行组装。
在所述阻尼装置中，导向滚轮120被所述缓冲轴设置在壳体中。缓冲件152在受到外力作用时，该缓冲件152发生弹性变形，从而可以在一定范围内移动。因此，导线200受到外力时，力传导至摩擦筒130，在摩擦筒130的带动下，缓冲件152的安装部可以在一定范围内移动。导向滚轮120与摩擦筒130之间存在间隔，当摩擦筒130移动至与该摩擦筒130的内表面与导向滚轮120的外表面相接触后，如导线仍继续移动、并驱动该导向滚轮120转动时，导向滚轮120与摩擦筒130之间将产生摩擦力，该摩擦力会阻止导向滚轮120的进一步转动。
当所述室外设备的固定装置失效、且所述室外设备从安装基础上脱落、并向下坠落时，会带动导线向下移动。如图4所示，导线受到所述室外设备带来的向下的作用力，具有从弯曲状态变成直线状态的趋势，从而上抬摩擦滚筒130，摩擦滚筒130带动缓冲件上移，使得导向滚轮120与缓冲件152产生作用力并压缩缓冲件152，最终使得缓冲件152产生弹性变形，并达到使得摩擦筒130与导向滚轮120接触的程度，导向滚轮120与摩擦筒130接触后，在摩擦力的作用下，导向滚轮120被卡住，无法进一步绕轴本体151转动。在所述室外设备下坠的过程中，导线始终与导向滚轮120紧密结合，因此，所述导线的表面与导向滚轮120的表面之间也存在摩擦力。当导向滚轮120被卡住、无法旋转后，导线也无法快速地从导向滚轮120滑过，因此，导线移动的速度会降低，甚至会停止移动，导线移动速度降低后，与导线相连的室外设备的坠落速度也会降低，导线停止移动后，室外设备也会停止下坠，从而可以降低室外设备从该室外设备的安装基础上脱落后伤人的风险。
还需要说明的是，缓冲件152在受到外力作用时产生弹性变形，当所述室外设备坠落时，导线经过缓冲件152的缓冲作用，移动一小段时间后才停止移动，并非即刻停止移动，因此，本公开所提供的阻 尼装置还可以避免因导线突然停止移动而被扯断，从而可以避免室外设备因坠落而造成停止运行，并避免室外设备的坠落影响用户使用所述室外设备。例如，当室外设备为CPE时，在CPE的导线上设置所述阻尼装置可以避免通信中断。
缓冲件152在处于变形状态时，存在弹性势能，释放弹性势能产生恢复力。解除所述室外设备因跌落而作用在导线上的力之后(例如，对室外设备进行了重新安装固定后)，弹性势能释放，在缓冲件152的恢复力作用下，摩擦筒130可以回到初始位置(即，缓冲件152处于初始状态时摩擦筒130所在的位置)，轻轻拉动导线时，导线滚轮120可以转动，并允许导线通过阻尼装置，并能够完成室外设备以及相应组件的重新安装。
在本公开中，对缓冲件152的具体结构不做特殊的限定，例如，缓冲件152可以是弹簧、弹性片等具有弹性的结构。缓冲件152还可以为电磁铁，当导向滚轮130下落至与摩擦筒接触时，电磁铁可以通电并吸附设置在导向滚轮120上或者摩擦筒130上的导磁件，使得导向滚轮120与摩擦筒130接触并产生摩擦力。
在本公开中，对摩擦筒130的表面状态没有特殊的要求，只要该摩擦筒130的外表面与导向滚轮120的外表面接触时产生的摩擦力能够阻碍导向滚轮130继续转动即可。
在本公开中，对制成摩擦筒130以及导向轮130的材料均不做特殊的限定。例如，可以利用塑料分别制成摩擦筒130以及导向轮130。
在本公开中，对壳体110的具体结构也不做特殊的限定。例如，如图1和图2中所示，壳体110可以包括底板111、环绕底板111设置的侧壁112、以及与底板111相对设置的顶板113。需要指出的还是，虽然图1和图2中示出的壳体110为矩形八面体结构，但是，本公开并不限于此，所述壳体110还可以为圆柱形、棱柱形等其他结构。
在本公开中，对如何将摩擦筒130与缓冲件152的安装部相对固定设置不做特殊的限定。例如，可以利用粘结件、或者紧固件直接将缓冲件152设置在摩擦筒的筒壁上。
在本公开中，为了便于设置，所述阻尼装置还可以包括安装板140，该安装板140固定设置在摩擦筒130背离底板111的一端，并且安装板140与底板111相对设置，且安装板140朝向摩擦筒130的内部延伸，以使得安装板140在底板111上的正投影的至少一部分落在摩擦筒130在底板111上的正投影所限定的区域内。缓冲件152的安装部固定设置在安装板140对应于摩擦筒130的内部空间的部分上。
通过设置安装板140，可以使得轴本体151位于摩擦筒130内部，并便于安装导向滚轮120，以使得导向滚轮120的外表面与摩擦筒130的内表面之间存在间隔。
作为一种实施方式，当所述阻尼装置组装完毕后、无外力作用的情况下，导向滚轮120的外表面与摩擦筒130的内表面之间均匀间隔。相应地，摩擦筒130为圆筒，所述阻尼装置组装完毕、且导线200穿过所述阻尼装置后，无外力作用的情况下，轴本体151的轴线与摩擦筒130的轴线重合。当摩擦筒130为圆筒时，导向滚轮120的外径小于摩擦筒130的内径。
为了限制摩擦筒130的移动范围，作为一种实施方式，如图4所示，安装板140上设置有安装孔141，缓冲件152设置在安装孔141中，轴本体151的一端插入安装孔141中。
由于安装孔141的尺寸是有限的，因此，轴本体151的一端仅能在安装孔141所限定的空间内移动，从而可以确保摩擦筒130必然能够移动至与导向滚轮120接触的位置。并且，一旦摩擦筒130移动至与导向滚轮120相接触的位置，便不会发生较大幅度的移动，确保导向滚轮120与摩擦筒130之间的摩擦力能够将导向滚轮锁定。
在本公开中，安装孔141可以沿厚度方向贯穿安装板140，也可以不贯穿安装板140，只要确保安装孔的一个开口朝向所述壳体的底板即可。
作为一种实施方式，安装孔为矩形孔，当所述阻尼装置、以及所述室外设备安装就位后，安装孔的长度方向为竖直方向。这样，轴本体151的背离所述壳体的底板的一端就可以在安装孔141的限定作用下做竖直方向的往复移动。
如上文中所述，壳体110包括底板111，轴本体151的一端朝向底板111。在本公开中，对轴本体151如何安装在壳体110的底板111上不做特殊的限定。例如，可以利用粘结件将轴本体151粘结在底 板111上，还可以在底板111上设置安装孔，将轴本体151插入安装孔中。
在图6中所示的实施方式中，底板111上设置有弧形的导向槽161，轴本体151的另一端插入弧形的导向槽161中，这样当缓冲件152被压缩、并使得导向滚轮120与摩擦筒130接触后，随着导线的进一步作用，轴本体151的一端仍然能够在导向槽161的引导下摆动，增加了所述阻尼装置受到的来自导线的冲击所持续的时间、从而可以减小阻尼装置冲击力(相应地，减小阻尼装置施加在导线上的反作用力)。即，导向滚轮120不会突然停止转动，从而可以避免导线因导向滚轮120的突然停转而被扯断。作为一种实施方式，当缓冲件152受到的力超过缓冲件152的初始弹力两倍时，轴本体151在导向槽161的引导下发生摆动。
图5中所示的是从顶板一侧观察阻尼装置的示意图，图中的圆形虚线为摩擦筒130的朝向壳体的底板的端面的轮廓，图中的圆弧形虚线为轴本体151的位于导向槽161中的一端的移动轨迹。
图6中所示的是从底板一侧观察阻尼装置的示意图，图中圆形虚线为摩擦筒130背离壳体的底板的端面的轮廓。并且，图6中还示出了轴本体151可以在导向槽161的引导作用下滑动。
为了便于摩擦筒130复位，作为一种实施方式，所述壳体的底板上还设置有辅助复位机构，所述辅助复位机构设置在所述导向槽的一端，并且，所述辅助复位机构能够在所述轴本体接触所述辅助复位机构时向所述轴本体提供远离所述辅助复位机构的推力。
在本公开中，对辅助复位机构的具体结构不做特殊限定。例如，所述辅助复位机构可以是设置在导向槽末端的弹簧或弹性片。当轴本体移动至导向槽末端时，会压缩所述辅助复位机构，辅助复位机构产生的恢复力有助于所述轴本体带动所述摩擦筒回归至初始位置。
作为一种实施方式，如图6所示，所述壳体的底板上还设置有与弧形的导向槽161连通的容纳腔162，轴本体151朝向所述壳体的底板的一端插入导向槽161中后与导向槽161的侧壁之间形成密封接触。所述阻尼装置还可以包括伸缩盖，所述伸缩盖设置在所述壳体的底板上，并覆盖所述容纳腔，所述伸缩盖与所述轴本体之间形成密封接触，且所述伸缩盖能够随所述轴本体的移动而伸缩，以使得所述容纳腔、所述导向槽、所述伸缩盖以及所述轴本体围成密封腔室。
在使用阻尼装置时，可以在所述容纳腔中设置液压油。由于所述导向槽与所述容纳腔连通，当轴本体处于初始位置时，液压油分布在导向槽以及容纳腔中。当轴本体发生摆动、将液压油完全挤压至容纳腔中后，液压油会产生推动轴本体的压力，有助于轴本体的复位。
在本公开中，可以先不向阻尼装置的容纳腔162中注入液压油。在需要将阻尼装置与室外设备组装在一起时，再向容纳腔162中注入液压油。
为了便于操作，可以预先向容纳腔162、导向槽161和所述伸缩盖形成的密封腔室中设置液压油。
当然，也可以不在所述容纳腔中设置液压油，只利用压缩气体所产生的气体压力也可以实现辅助所述轴本体复位的作用。
如上文中所述，导线200在导向滚轮120和摩擦筒130之间的间隔中绕过导向滚轮120。为了便于导线200带动导向滚轮120转动、并实现导向滚轮120与摩擦筒130接触后的自锁，导线200可以绕导向滚轮120的半周。
摩擦筒130和壳体110设置为导线200依次穿过所述第一导线入孔、所述第二导线入孔、所述第二导线出孔、所述第一导线出孔、且缓冲件152处于初始状态时，所述第一导线入孔、所述第二导线入孔、所述第二导线出孔、所述第一导线出孔排列在同一直线上，以使得所述导线至少绕所述导向滚轮半周。换言之地，当摩擦筒130处于初始状态时，第一导线入孔112a、第二导线入孔130a、第二导线出孔130b、第一导线出孔112b依次排列在同一直线上，以使得所述导线至少绕所述导线滚轮半周。
作为本公开的一种实施方式，如图2中所示，摩擦筒130和壳体110设置为导线200依次穿过所述第一导线入孔、所述第二导线入孔、所述第二导线出孔、所述第一导线出孔、且缓冲件152处于初始状态时，第一导线入孔112a、第二导线入孔130a、第二导线出孔130b、第一导线出孔112b依次排列在导向滚轮120的直径所在的直线上，从而可以使得导线200绕导向滚轮120半周。换言之，当摩擦筒130处于初始状态时，第一导线入孔112a、第二导线入孔130a、第二导线出孔130b、第一导线出孔112b依次排列在导向滚轮120的直径所在的直线上，从而可以使得导线200绕导向滚轮120半周。
作为本公开的第二个方面，提供一种CPE组件，所述CPE组件包括CPE，其中，所述CPE组件还包括本公开第一个方面所提供的上述阻尼装置，所述CPE的导线分别穿过所述第一导线入孔、第二导线入孔进入所述摩擦筒与所述导向滚轮之间的间隙，并且所述导线绕过所述导向滚轮通过所述第二导线出孔和所述第一导线出孔从所述阻尼装置穿出。
在使用时，所述CPE设置在室外，本公开所提供的阻尼装置设置在室内。在安装时，CPE的导线200的一端通过壳体110的第一导线入孔112a进入壳体110内部，随后导线200的一端通过摩擦筒130上的第二导线入孔130a进入摩擦筒130和导向滚轮120之间的间隔。导线在摩擦筒130和导向滚轮120之间的间隔绕过导向滚轮120并从摩擦筒130上的第二导线出孔130b穿出，最终导线通过壳体110的侧壁112上的第一导线出孔112b从阻尼装置中穿出，并与室内的电子设备相连，这就使得在初始状态下，摩擦筒130被导线200悬挂在壳体110内。
当CPE固定在相应的安装基础上时，如图3所示，所述阻尼装置中，摩擦筒130在导线200的作用下，在所述阻尼装置的壳体110内悬空，并且导向滚轮120与摩擦筒130之间无接触。当以较慢的速度抽拉导线200时，导向滚轮120可以绕所述轴本体旋转，从而可以完成阻尼装置与室外设备的导线进行组装。
在所述阻尼装置中，导向滚轮120被所述缓冲轴设置在壳体中。缓冲件152在受到外力作用时，该缓冲件152发生弹性变形，从而可以在一定范围内移动。因此，导线200受到外力时，力传导至轴本体151，在轴本体151的带动下，缓冲件152可以在一定范围内移动，最终使得摩擦筒130也可以在一定范围内移动。导向滚轮120与摩擦筒130之间存在间隔，当摩擦筒130移动至与该摩擦筒130的内表面与导向滚轮120的外表面相接触后，如导线仍继续移动、并驱动该导向滚轮120转动时，导向滚轮120与摩擦筒130之间将产生摩擦力，该摩擦力会阻止导向滚轮120的进一步转动。
当所述CPE的固定装置失效、且所述CPE从安装基础上脱落、并向下坠落时，会带动导线向下移动。如图4所示，导线受到所述室外设备带来的向下的作用力，导向滚轮120带动轴本体151下压缓冲件152，使缓冲件152产生弹性变形，并达到使得摩擦筒130与导向滚轮120接触的程度，导向滚轮120与摩擦筒130接触后，在摩擦力的作用下，导向滚轮120被卡住，无法进一步绕轴本体151转动。在所述CPE下坠的过程中，导线始终与导向滚轮120紧密结合，因此，所述导线的表面与导向滚轮120的表面之间也存在摩擦力。当导向滚轮120被卡住、无法旋转后，导线也无法快速地从导向滚轮120滑过，因此，导线移动的速度会降低，甚至会停止移动，导线移动速度降低后，与导线相连的CPE的坠落速度也会降低，导线停止移动后，CPE也会停止下坠，从而可以降低CPE从该CPE的安装基础上脱落后伤人的风险。
还需要说明的是，缓冲件152在受到外力作用时产生弹性变形，当所述CPE坠落时，导线经过缓冲件152的缓冲作用，移动一小段时间后才停止移动，并非即刻停止移动，因此，本公开所提供的阻尼装置还可以避免因导线突然停止移动而被扯断，从而可以避免CPE因坠落而造成停止运行，并避免通信中断。
缓冲件152在处于变形状态时，能够产生恢复力。解除所述CPE因跌落而作用在导线上的力之后(例如，对CPE进行了重新安装固定后)，弹性势能释放，在缓冲件152的恢复力作用下，摩擦筒130可以回到初始位置，轻轻拉动导线时，导线滚轮120可以转动，并允许导线通过阻尼装置，并能够完成CPE以及相应组件的重新安装。
对于CPE而言，导线200为数据线。
本文已经公开了示例实施例，并且虽然采用了具体术语，但它们仅用于并仅应当被解释为一般说明性含义，并且不用于限制的目的。在一些实例中，对本领域技术人员显而易见的是，除非另外明确指出，否则可单独使用与特定实施例相结合描述的特征、特性和/或元素，或可与其它实施例相结合描述的特征、特性和/或元件组合使用。因此，本领域技术人员将理解，在不脱离由所附的权利要求阐明的本公开的范围的情况下，可进行各种形式和细节上的改变。
