背景技术
在现有网络的通讯中继环节中，尤其是偏向终端的节点处，基本都是选用小型机柜或者模块之类的结构作为载体。出于使用维护的需求，在此类结构上，通常存在门板、盖板之类的结构，以旋转打开的方式，露出腔体内部线路结构，方便现场维护操作。此类节点大多存在于户外、高空，以挂装形式存在，考虑到门板、盖板等重量以及户外作业时经常出现的大风，而操作过程通常是单人操作的情况，出于维护便捷性和操作人员安全角度考虑，需要门板、盖板等在打开状态下保持位置不变，所以对应的转动连接机构需要一定的静态摩擦力，即阻尼的存在。
相关技术中，门板、盖板等与小型机柜、模块等之间的转动连接机构一般采用铰链结构，在一种方案中，铰链包括底板、第一立板、第二立板和枢转轴，第一立板和第二立板设置在底板的两端，第一立板和第二立板分别与底板一体成型，第一立板开设有第一通孔，第二立板开设有第二通孔，第一通孔设有第一边轴，第二通孔设有第二边轴，枢转轴的一端插入第一边轴中，枢转轴的另一端插入第二边轴中，底板开设有第一定位孔、枢转轴开设有第二定位孔，通过第一定位孔使用螺钉可将铰链连接到物体上，通过第二定位孔使用螺钉可将门连接到铰链上。
但是，上述铰链结构存在零件数目多、装配效率低、成本较高的问题。并且，上述铰链结构仅适合跨度定距装配，当跨度变化时，需要不同规格的铰链，产品规格的统一化较低。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请，下面将结合附图对本申请实施例的实施方式进行详细描述。
铰链是目前最常用的转动连接机构，铰链又称合页是用来连接两个固体并允许两者之间做相对转动的机械装置。铰链可由可移动的组件构成，或者由可折叠的材料构成。铰链一般用在门窗或者橱柜上，其特点是在柜门关闭时带来缓冲功能，最大程度的减小柜门关闭时与柜体碰撞发出的噪音，或者使柜门在打开状态下保持位置不变，便于使用者从柜中取物或者避免柜门夹伤使用者。
但是，现有的铰链结构一般都存在结构复杂、制造成本高、转动不灵活、使用寿命短等问题，并且无法在室外环境下长期使用，不能适用于例如网络通讯中继环节中以挂装形式存在于户外、高空的机柜或者模块类结构中。所以对上述问题进行改进便成为亟需解决的问题。
图1为一铰链的结构示意图，参考图1所示，铰链1包括底板2、第一立板3、第二立板4和枢转轴5，第一立板3和第二立板4设于底板2的两端，第一立板3和第二立板4分别与底板2一体成型，第一立板3开设有第一通孔6，第二立板4开设有第二通孔7，枢转轴5的两端分别在第一通孔6和第二通孔7中转动设置，底板2上开设有第一定位孔8，枢转轴5上开设有第二定位孔9，第一定位孔8用于将铰链1连接到物体上，第二定位孔9用于将门连接到铰链1上。
图2为图1中提供的铰链的一应用场景图，其铰链1可以应用在机柜10上，结合图1和图2所示，机柜10包括：机柜本体11、门板12以及图1中所示的铰链1。铰链1通过6个紧固件穿过第一定位孔8与机柜本体11紧固连接，通过5个紧固件穿过第二定位孔9与门板 12紧固连接，实现门板12与机柜本体11之间的转动，并且铰链1具有一定阻尼效果，在门板12在打开状态下可以保持位置不变。
虽然图1中所示的铰链1在传统的铰链上进行了改进，但是仍旧存在一系列问题。
例如，图3为图1中提供的铰链的分解结构示意图，参考图3所示，图1中所示铰链1具有核心部件10件，零件数目多；涉及的工艺包括：钣金工艺、机加工艺、冷镦工艺、注塑工艺、模切工艺等，涉及的加工工艺多。
再例如，铰链1需要使用6个紧固件通过第一定位孔8将铰链1连接到机柜本体11上，再使用5个紧固件通过第二定位孔9将门板12连接到铰链1上，其装配需要采用紧固件11件，并且还需要在机柜本体11和门板12上机加对应的孔洞，配零件较多、装配过程复杂，从而导致装配效率低，进而导致成本偏高。
另外，由于铰链1中底板2的长度已经固定，当门板12与机柜本体11转动连接处的宽度发生变化时，铰链1的规格也要随之改变，所以图1中所示的铰链1仅适合跨度定距装配，当跨度变化时，便需要采用不同规格的铰链1，导致产品规格的统一化较低。
为了解决上述问题，本申请实施例提供一种机柜及阻尼销，其中，阻尼销包括公轴和母轴两个核心部件，涉及工艺和零件数目少。并且，阻尼销应用在机柜中时，无需采用装配零件。从而可提高装配效率，降低成本。另外，阻尼销还可适用于不同跨度、不同阻尼力大小的多种工况，有利于提高产品规格的统一化。
下面结合附图对本申请提供的实施例作详细描述。
图4为本申请一实施例提供的机柜200的结构示意图，图5为图4中提供的机柜200的分解结构示意图，参考图4和图5所示，本申请实施例提供的机柜200包括：壳体20、与壳体20转动设置的盖板30以及至少一个阻尼销40，示例性的，在本实施例中，以阻尼销40为两个进行说明。
其中，图6为本申请一实施例提供的阻尼销40的结构示意图，图7为图6中提供的阻尼销40的剖面结构示意图。参考图6和图7所示，本申请实施例提供一种阻尼销40，可作为物体间的转动连接机构，包括：公轴41以及母轴42。
其中，公轴41包括大头端411以及与大头端411一端端面连接的插销412，母轴42具有插孔421，插销412转动设置在插孔421中，并且至少部分插销412的外侧壁与插孔421的内侧壁过盈配合。通过插销412的外侧壁与插孔421的内侧壁过盈配合可实现阻尼销40的阻尼效果，并且可以通过调整插销412的外侧壁与插孔421的内侧壁之间的过盈量、插销412与插孔421的配合长度和插销412外柱面的大小可对阻尼力进行调整以满足各种工况的需求。
图8为本申请实施例提供的阻尼销40与第一安装座21和第二安装座31装配后的剖面图，结合图5和图8所示，壳体20具有第一安装座21，盖板30具有第二安装座31，示例性的，在本申请附图中，第一安装座21和第二安装座31均具有安装孔，阻尼销40穿过安装孔使得阻尼销40的大头端411和阻尼销40的母轴42中的其中一个固定装配在第一安装座21内，阻尼销40的大头端411和阻尼销40的另一个固定装配于第二安装座31内。本申请实施例中，以大头端411固定装配于第一安装座21内，母轴42固定安装在第二安装座31内为例进行说明。当然，在本申请的其他实施例中，也可以是，大头端411装配于第二安装座31内，母轴42安装在第一安装座21内。
完成装配后，转动盖板30，第二安装座31带动母轴42转动，由于第一安装座21位于壳体20上，第一安装座21使得大头端411保持不动，如此，便可实现盖板30与壳体20之间的转动连接。并且，由于阻尼销40阻尼力力的存在，在盖板30打开后，盖板30可以保持 位置不变，便于操作人员对机柜200进行维护，具有一定的防误夹功能，保证操作人员的安全性。常见应用场景包括室外模块、机柜等，对于高空作业的操作人员，可起到释放双手的作用。
应理解的是，本申请实施例提供的阻尼销40，包括公轴41和母轴42两个核心部件，相比相关技术中的转动连接机构，零件数目大为减少。并且，本申请实施例提供的阻尼销40涉及冷镦工艺和机加工艺，加工工艺和加工工序少。另外，本申请实施例提供的阻尼销40与器件连接时采用的装配零件少甚至不需要装配零件。综上，本申请实施例提供的阻尼销40可有效减少零件数量和装配零件数量，减少装配量和装配空间，提升装配效率，减少成本。再者，本申请实施例提供的阻尼销40体积小，当转动连接部位跨度发生变化时，可根据具体工况设置一个、两个或两个以上的阻尼销40，无需对阻尼销40的规格进行变更，有利于产品规格的统一化。
另外，本申请实施例提供的阻尼销40在阻尼力方面还具有可编辑性，一般情况下，阻尼销40为配对使用，当转动连接部位跨度较大时，可在两个阻尼销40之间增加一个或更多阻尼销40，多个阻尼销40的阻尼力可以不同，装配时可通过排列组合方式，实现不同的阻尼效果。
例如，图9为本申请实施例提供的阻尼销40的阻尼力可编辑性的解释图，参考图9所示，以两种阻尼销40和两个装配位置为例进行说明，图9中，两种阻尼销40分别具有阻尼力a和阻尼力b，a不等于b，将阻尼销40装配于第一安装座21和第二安装座31中，通过搭配，可实现总阻尼力a+a、a+b、b+b三种不同的阻尼效果。同时，因两个阻尼销40独立存在，故不受两个装配位置之间的间距限制。
又例如，以两种阻尼销40和三个装配位置为例进行说明，两种阻尼销40分别具有阻尼力a和阻尼力b，a不等于b，通过搭配，可实现总阻尼力a+a+a、a+a+b、a+b+b、b+b+b四种不同的阻尼效果。
需要说明的是，在本申请实施例中，在壳体20上设置第一安装座21，在盖板30上设置第二安装座31仅为一种示例，当然也可以将阻尼销40直接与壳体20和盖板30进行连接，比如，可以将阻尼销40的大头端411和母轴42分别与壳体20和盖板30进行焊接、卡接、粘接等常规连接方式。在此，对阻尼销40与壳体20和盖板30之间的连接方式不做限定，只需保证阻尼销40的大头端411与母轴42分别与壳体20和盖板30中的其中一个连接，使得大头端411与母轴42之间能进行相对转动即可。
可以理解的是，本申请实施例提供的阻尼销40不限于应用在通信领域户外机柜200或模块在维护时盖板30的敞开定位，作为一种极简的转动阻尼系统，可在更改其体积大小后通过灵活搭配各种形态的零件，应用在家用、玩具等多种设计有旋转阻尼系统的领域。
当然本申请不止于此，继续参考图7所示，在本申请的一些实施例中，可以在插孔421的内侧壁上设置第一限位凸台4211，第一限位凸台4211与插销412卡接可以限制插销412在插孔421的轴向上的位移，示例性的，如图7所示，可以将插销412远离大头端411的一端与第一限位凸台4211卡接，防止公轴41和母轴42在使用过程中松脱，保证阻尼销40的结构稳定性。
继续参考图7所示，作为一种插销412与第一限位凸台4211卡接的实施方式，可以在插销412远离大头端411的一端设置盲孔4121，此时，插孔421可以为母轴42内设置的通孔，当插销412插入插孔421后，在插孔421远离大头端411的一端对盲孔4121采取旋铆涨开工艺，使盲孔4121对应的插销412的外径大于第一限位凸台4211的内径，从而使盲孔4121的 外侧壁与第一限位凸台4211卡接，防止公轴41和母轴42在使用过程中松脱，保证阻尼销40的结构稳定性。
图10为本申请一实施例提供的阻尼销40的分解结构示意图，图11为图10的剖面结构示意图，参考图10和图11所示，在本申请的一些实施例中，阻尼销40还可以包括：环形弹片43，环形弹片43用于套设在盲孔4121的外侧壁上，并且环形弹片43的外周壁与插孔421的内侧壁过盈配合，通过调节环形弹片43与插孔421的过盈量可对阻尼力起到一定的辅助调节作用。
继续参考图10和图11所示，在本申请的一些实施例中，阻尼销40还可以包括：密封盖44，密封盖44封盖在插孔421远离大头端411的一端，起到防尘、密封、防水以及装饰作用，使阻尼销40适应于户外等多种工况。
参考图10所示，在本申请的一些实施例中，还可在插销412的外侧壁上开设凹槽4122，凹槽4122用于存储辅助介质，例如阻尼膏等，以降低公轴41和母轴42相对转动过程中产生的热量，减少磨损，提升阻尼销40的使用寿命。
其中，凹槽4122可采用如图10中与插销412轴向平行的直槽，也可采用与插销412轴向垂直的环形槽，还可为在插销412外侧壁上的螺旋槽等，在此，对凹槽4122的数量以及形状不做限制。
继续参考图10所示，在本申请的一些实施例中，阻尼销40的大头端411远离插销412的一端呈导向曲面状，为阻尼销40安装于第一安装座21和第二安装座31内提供导向作用。还可在母轴42远离大头端411的外侧壁上设置第二限位凸台422，第二限位凸台422在阻尼销40安装于第一安装座21和第二安装座31后起到止动作用。
阻尼销40的装配方式可参照图12所示，图12为本申请一实施例提供的阻尼销40装配于第一安装座21和第二安装座31的装配示意图，阻尼销40的装配方式为单向插入，第一安装座21和第二安装座31的安装孔重叠好之后，从第二安装座31一侧，使阻尼销40具有导向曲面状的大头端411先入，直到第二限位凸台422与第二安装座31止动为止。
当然，阻尼销40的装配方式也可以是双向插入，此时，阻尼销40的外观如图13所示，图13为本申请一实施例提供的阻尼销40的外观图，如图13所示，阻尼销40的大头端411远离插销412的一端以及母轴42远离大头端411的一端均呈导线曲面状，整体类似于胶囊形态。母轴42远离大头端411的一端不再具有第二限位凸台422，其他特征均同上述阻尼销40具有的特征相同。该阻尼销40可以一端先固定装配于第一安装座21，然后另一端再固定装配于第二安装座31。
继续参考图6和图13所示，在本申请实施例中，关于阻尼销40固定于第一安装座21和第二安装座31的固定方式可以为，在大头端411的外周面和母轴42的外周面上设置滚花45，大头端411上的滚花45和母轴42上滚花45分别与第一安装座21和第二安装座31的安装孔的内侧壁铆接配合，以此来完成阻尼销40与第一安装座21和第二安装座31的固定安装。此时，应确保滚花45与对应装配区域的铆合抗扭力大于插销412和插孔421的配合阻尼力，确保装配好后不存在盖板30晃动的问题。可以理解的是，通过滚花45与第一安装座21和第二安装座31的安装孔铆合装配的方式，可以使得装配简单易行，使用场景广泛，可有效节省装配解空间，节省螺钉装配时所需的螺纹孔机加。
需要提到的是，关于阻尼销40与第一安装座21和第二安装座31的固定装配方式还可以利用阻尼销40、第一安装座21和第二安装座31异形截面形式，例如，可以将阻尼销40的的整体外观设置成柱状体，第一安装座21和第二安装座31的安装孔设计成矩形孔，将横截 面为矩形的阻尼销40插入矩形的安装孔中完成阻尼销40与第一安装座21和第二安装座31的装配。
综上，本申请采用功能细分、高度解耦的方法，将承担转动阻尼效果的核心部件提取出来，并以阻尼销的形式存在。在一定程度上，规避阻尼力、装配装配间距、装配方式等因素对于转动连接机构的影响，对于提升装配灵活性、降低装配难度、节省装配空间、缩减成本及增强产品形态归一化方面，起到了重大的改善作用。
本申请实施例提供的阻尼销的优势可以主要归纳于三个方面：
1、传统的转动连接机构装配零件和加工工序繁多。本申请提供的阻尼销加工工艺种类和零部件数量均减少50％，大幅度减少了零件种类和加工工序，减少了阻尼件重量，提升了装配效率，有利于自动化设备制造。
2、传统的转动连接机构装配过程繁琐，涉及11个孔位的机加，匹配装配是采用螺钉、销钉等零件。本申请提供的阻尼销采用穿插铆合方式装配，不涉及定位销轴和装配螺钉，可有效提升阻尼系统的装配效率，节省装配时间60％以上。
3、传统的转动连接机构选型种类受限自身跨度和阻尼的制约，其对于不同跨度的诉求无法兼容。本申请提供的阻尼销采用配对方式使用，可兼容多种跨度，同时可通过不同阻尼力的阻尼销搭配的方式，实现多种组合阻尼力，可有效提升产品的归一化水平。
