具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。在本申请的说明书、权利要求书及上述附图中描述的一些流程中，包含了按照特定顺序出现的多个操作，这些操作可以不按照其在本文中出现的顺序来执行或并行执行。操作的序号如101、102等，仅仅是用于区分各个不同的操作，序号本身不代表任何的执行顺序。另外，这些流程可以包括更多或更少的操作，并且这些操作可以按顺序执行或并行执行。需要说明的是，本文中的“第一”、“第二”等描述，是用于区分不同的模块、模型、设备等，不代表先后顺序，也不限定“第一”和“第二”是不同的类型。此外，下述的各实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1a、图1b、图3a和图3b分别示出了本申请实施例提供的两种计算机用扩展模组实现结构的示意图。参见图1a、图1b、图3a所示，所述扩展模组100包括托架1及第一电路板2。其中，托架1上设有连接装置。第一电路板2，其设置在所述托架1上，且所述第一电路板2具有用于电连接所述计算机的电连接结构21以及用于电连接外部设备 的电连接端口22，所述第一电路板2通过线缆与所述计算机电连接；所述第一电路板2具有相对的两端，所述电连接结构21自所述第一电路板的第一端引出或位于所述第一电路板2的第一端，所述第一电路板2的第二端设有所述电连接端口22；所述托架1的端部设有与所述安装口适配的端板12，所述端板12上设有第一通孔，所述电连接端口22通过所述第一通孔伸出，使得所述扩展模组100连接到所述计算机上时所述电连接端口22外露。
所述连接装置包括锁紧结构及释放部件31。参见图2所示，在所述扩展卡模组100自所述计算机壳体6上的安装口61插入后，所述锁紧结构锁紧使得所述扩展卡模组100与所述壳体6内部结构连接，且所述释放部件31及所述电连接端口22外露；所述释放部件31被触发后，所述锁紧结构解锁使得所述扩展卡模组100与所述壳体6内部结构脱开连接。
具体的，如图2所示的实施例，所述计算机的壳体6内可设有但不限于：安装架63。所述安装架63具有相对设置、且间隔开形成第二安装空间62的两个立架。所述两个立架中的一个立架上设有与所述锁紧结构配合的适配结构。该立架上的所述适配结构即上文中提及的所述壳体6内部结构。所述锁紧结构与所述适配结构配合，实现所述锁紧结构的锁紧使得所述扩展卡模组100与计算机连接。例如，所述锁紧结构包括卡钩，相应的壳体6内部结构可以是与卡钩适配的卡孔。扩展卡模组插入至所述卡钩与所述壳体6内部的卡孔位置对应时，卡钩卡入卡孔内，完成锁紧。
进一步的，如图2所示，两个立架上可设置有引导槽。引导槽可以是如图2中所示的结构形成的，用来引导扩展模组100的插入。如图2所示，立架上设有多个孔，孔边缘向第二安装空间内突出，上下两个孔的相邻的两条孔边缘可形成所述引导槽。在所述立架上设置孔，一是可以减轻计算机整机重量，二是能形成所述引导槽，用以引导扩展模组的插入方向。再进一步的，如图2所示，两个立架之间设置有末端板，所述末端板与两个立架围成一个U字形第二安装空间。
本实施例中所述的释放部件31的触发可人为触发。例如，按下释放部件，或拔出释放部件、或旋转释放部件等方式触发。本实施例中的所述锁紧结构与释放部件联动，比如所述释放部件被向外拔出，所述锁紧结构解锁；或者，所述释放部件被按下，所述锁紧结构解锁；又或者，旋转释放部件，所述锁紧结构解锁；等等。
图5示出了连接装置的一种可实现的方案。参见图5所示，所述锁紧结构包括弹性执行件32。所述释放部件31位于设定位置时，所述弹性执行件32处于伸出状态，所述扩展卡模组100自所述安装口61插入过程，所述弹性执行件32受力形变缩回；所述扩展卡模组100插入至与所述壳体6内部结构位置对应时，所述弹性执行件32复位至所述伸出状态，与所述壳体6内部结构配合，将所述扩展卡模组100连接在所述计算机上。具体的，如弹性执行件32包括卡钩322，卡钩322在扩展模组插入计算机的第二安装空 间的过程先形变缩回，然后扩展模组插入到卡钩322的位置与壳体内部结构(即立架上的卡孔)位置对应时，卡钩322弹性复位处于伸出状态，并插入卡孔内。被触发的所述释放部件31离开所述设定位置，如图6所示，所述弹性执行件32随所述释放部件31动作至缩回状态，所述扩展卡模组100与所述壳体6内部对应结构脱开连接。
继续参见图5所示，所述释放部件31通过螺纹连接在所述托架1上。具体实施时，所述释放部件31可以是拇指螺丝。所述释放部件31与所述托架1接触时处于所述设定位置；如图6所示，通过螺纹旋转所述释放部件31远离所述托架1的过程，即触发所述释放部件31离开所述设定位置的过程。
在一种可实现的技术方案中，如图5和图6所示，所述弹性执行件32包括扭簧321及固定件323，所述扭簧321具有第一弹性端及第二弹性端；所述第一弹性端设有卡钩322；所述第二弹性端随所述释放部件31动作；所述固定件323设置在托架1上，所述扭簧321套设在所述固定件323上。
进一步的，所述扭簧321第二弹性端与所述释放部件31的随动，可以是通过将所述扭簧321第二弹性端与释放部件31连接来实现随动。释放部件31可直接与扭簧的第二弹性端连接，也可通过中间件与扭簧的第二弹性端连接。通过连接实现随动，容易理解，因为扭簧的第二弹性端与释放部件31直接或间接连接，释放部件31动作，扭簧就会跟着动作。在释放部件31远离托架1的移动时，扭簧321的第二弹性端随着移动，使得扭簧321绕固定件323旋转，进而所述扭簧321的第一弹性端缩回至缩回状态。此时，卡钩322从壳体6内部结构的卡孔出来，扩展模组100便与计算机脱开连接，向外抽即可将扩展模组100拔出。
如图5和图6所示的释放部件和扭簧的结构设计，可实现扩展模组插入计算机的壳体时，卡钩自动弹出实现扩展模组自锁固定；但扩展模组要拔出计算机时，必须拧动释放部件(如拧松以远离托架)，才能使卡钩解锁。这样的设计同时还可达到安装和拆卸时的防呆功能：插入时，不需要释放部件，即可保证扩展模组可靠自锁固定；拔出时，则必须触发释放部件(通过螺纹旋转)解锁，防止意外误操作将扩展模组拔出。
如图2和图4所示，所述安装口61可设置计算机壳体6的前面板或后面板上，这样，扩展模组100便可从计算机壳体6的前面板或后面板上插入或拔出，实现无需拆下壳体面板插拔扩展模组的目的。若本实施例提供的扩展模组安装的计算机为数据中心的服务器，则采用本实施例提供的方案服务器即可在服务器不下架的情况下，实现扩展模型的插拔更换，可节省大量的时间，缓解拆卸不便的问题，运维时停机时长可大大缩短。
综上内容可知，本申请实施例提供的技术方案的关键创新点包括但不限于如下几点：
1、实现免拆计算机壳体的方式拆装扩展模组，方便扩展模组的更换或检修。
2、具有防呆设计的连接装置。如上述内容，安装扩展模组时直接将扩展模组插入计算机壳体上安装口内的第二安装空间内，锁紧装置便能自动锁紧；在需要拆卸扩展模组 时，需用户触发释放部件(如拧松释放部件)，扩展模组才能脱开与计算机的连接，这样的防呆设计可防止意外误操作将扩展模组拔出。
进一步的，所述第一电路板2具有相对的两端，所述电连接结构21自所述第一电路板的第一端引出或位于所述第一电路板2的第一端，所述第一电路板2的第二端设有所述电连接端口22。所述托架1具有相对的两端，所述托架1的第一端与所述第一电路板2的第一端对应，所述托架1的第二端与所述第一电路板2的第二端对应；所述托架1的第二端设有与所述安装口61适配的端板12，所述端板12上设有第一通孔；所述电连接端口22通过所述第一通孔伸出。这样在扩展模组安装到计算机的壳体内后，端板12及伸出所述端板12的电连接端口22外露，这样便于通过电连接端口22连接外部设备。所述释放部件31设置在所述端板12上，并位于所述电连接端口22的一侧。在扩展模组安装到计算机的壳体内后，释放部件31也外露，这样方便触发(如旋转、拔出或按下等等)。
如图1a和图1b所示的一种实施例的结构，所述电连接结构21为位于所述第一电路板2的第一端处的插接结构，所述插接结构在所述托架1的第一端处超出所述托架1，以便于所述插接结构插入对应的电连接插槽。在一个具体的应用场景中，本实施例中的计算机可为服务器。比如在数据中心中部署的服务器集群，多个服务器需通过PCIE扩展模组进行互联。即，本实施例中的第一电路板2可以是PCIE扩展电路板，所述电连接结构21为所述PCIE扩展电路板上的金手指结构。
如图2所示，所述计算机壳体内部结构中的末端板(上文中有提及)上可设置有电连接插槽。具体实施时，如图2所示，该电连接插槽7可以是用于电连接第一电路板2与线缆81电连接的插槽。例如，第一电路板2为PCIE扩展电路板，其上设有金手指结构，该电连接插槽7与该金手指结构适配。另外，线缆81可以是cable(有限电视)线缆。此处，使用线缆将扩展模组(即其包括的第一电路板2)和计算机内部的部件(如主板)电连接，省去转接板(riser转接板)，有助于提升扩展模组的高速信号传输质量，降低转接板对信号传输质量的不利影响。
对于现有计算机(如服务器)上已使用的PCIE扩展卡，这类扩展卡大多为图3c中所示的扩展卡结构。对于这类PCIE扩展卡来说，想采用上述实施例对应的设计思想，为方便拆装。本实施例还提供了一种可兼容已有PCIE扩展卡的方案。如图3a和3b所示，所述第一电路板2可以是图3c所示的PCIE扩展卡。所述托架1上设有第二电路板8，所述第二电路板8上设有连接电路、插座及线缆。图3a和3b中未详细示出第二电路板8的结构，可参见图3c。所述连接电路分别与所述插座与线缆的一端电连接。所述PCIE扩展卡的插接结构插入所述插座上。相应的，所述电连接结构21为图3a和图3b中示出的从第二电路板8引出的所述线缆81，所述线缆81从所述PCIE扩展卡的第一端(即与所述PCIE扩展卡的电连接端口相对的一端)引出。
同样的，所述线缆81可以是cable(有限电视)线缆，或其他类型的线缆，本实施例对此不作限定。
更具体的，如图3a和图3b所示，所述托架1的对应所述PCIE扩展卡的第一端(即与所述PCIE扩展卡的电连接端口相对的一端)的端部可设置有卡尾限位件15。
进一步的，所述第二电路板8位于所述PCIE扩展卡的一侧；所述第二电路板8具有朝向所述PCIE扩展卡的第一面以及背向所述PCIE扩展卡的第二面；所述插座位于所述第一面；所述线缆81的一端位于所述第二面；所述线缆81自所述第二面引出至所述第二面，并在所述第二面侧收拢于线缆护板16内，沿着所述线缆护板16从所述PCIE扩展卡的第一端(即与所述PCIE扩展卡的电连接端口相对的一端)引出，以与所述计算机电连接。如图4所示，所述第二电路板8上引出的线缆81自所述PCIE扩展卡的第一端延伸出以与计算机的主板电连接。
如图3c中所示的PCIE扩展卡，电连接端口22设置在PCIE扩展卡的端部，金手指结构(即本文中提及的电连接结构的一种具体的实现形式)位于PCIE扩展卡的侧边。对于图3c中所示的PCIE扩展卡，本实施例中的第二电路板8可设置在托架的第二侧板112处。例如，图3c中示出的第二电路板8与第二侧板112平行设置，第二电路板8的第一面背向其紧挨的第二侧板112；第二电路板8的第二面朝向其紧挨的第二侧板112。安装PCIE扩展卡时，托架1上的第一侧板111处敞开，将安装PCIE扩展卡自第一侧板111处插入以使PCIE扩展卡的金手指结构插入第二电路板8的第一面上的插座，然后使用紧固件(如螺钉)将第一侧板111安装在托架1的托板上或图3b中的卡尾限位件的端部上。
如图4所示，所述PCIE扩展卡安装在如图3a所示的托架上后，PCIE扩展卡便于托架上的第二电路板完成了电连接；PCIE扩展卡的金手指结构(即电连接结构的一种实现形式)通过托架上的线缆81被引出。然后，直接通过线缆81与计算机电连接，比如通过线缆81与计算机的主板电连接，省去了转接板，有助于提升扩展模组的高速信号传输质量，降低转接板对信号传输质量的不利影响。
本实施例中的所述托架的结构可参见图1a、图1b、图3a和图3b所示。所述托架1包括：托板(未明确示出)、两个侧板及所述端板12。其中，两个侧板分别为第一侧板111、第二侧板112。第一侧板111和第二侧板112及所述端板12均设置在所述托板的板边缘，且所述端板12位于所述两个侧板之间。所述锁紧结构包括卡钩322；所述两个侧板中的一个侧板上设有开口。如图1所示的实施例，第二侧板112上设有开口。所述卡钩322能伸出所述开口用以与所述壳体6内部结构(如卡孔)连接，所述卡钩322还能从所述开口处缩回用以与所述壳体6内部结构脱开连接。
进一步的，如图1a、图1b、图3a和图3b所示，所述端板12上设有与所述托板平行的顶板13；所述顶板13及所述托板的底部中的至少一个上设有弹性条5，所述弹性条 5用于与所述安装口61的相应侧口内壁相抵接。
再进一步的，如图1a、图1b、图3a和图3b所示，所述托架1还包括两个连接板14；所述端板12位于所述两个连接板14之间；所述两个连接板14在所述托架1的第二端处，分别与对应侧的所述顶板13的板边缘、所述端板12的板边缘及侧板(即第一侧板111和第二侧板112)的板边缘连接；所述两个连接板14中的至少一个连接板上设有弹性件4，所述弹性件4用于与所述安装口61的相应侧口内壁相抵接。
通过设置弹性条5可消除扩展模组与安装口的口内壁在第一方向上的间隙，可防止扩展模组100在第一方向上的晃动。上述弹性件4的设置可消除扩展模组与安装口的口内壁在第二方向上的间隙，可防止扩展模组100在第二方向上的晃动。其中，第一方向和第二方向垂直。例如，第一方向为竖直方向，第二方向为水平方向。
图7和图8示出了连接装置的另一种可实现结构。参见图7和图8所示，所述连接装置包括杠杆扳手52。所述杠杆扳手52的一端与所述托架1旋转连接，所述杠杆扳手52的位于旋转轴53的位置处设有插舌54，所述托架1的对应所述插舌54的位置处设有开口，便于所述插舌54在所述开口处伸缩。所述杠杆扳手52的远离所述旋转轴53的另一端设有把手552及紧固结构551，所述托架1上设有与所述紧固结构551配合工作的配合结构。如图7所示，在所述扩展卡模组自所述计算机壳体上的安装口插入后，所述杠杆扳手52的远端(即把手552端)朝靠近所述托架1的方向旋转，所述插舌54伸出(如图7所示)与所述壳体内部结构连接，所述杠杆扳手52的远端旋转至与所述托架1的配合结构对应时，通过所述紧固结构551与所述配合结构锁定所述扩展卡模组与所述计算机壳体的连接；如图8所示，所述紧固结构551与所述配合结构脱开连接后，所述杠杆扳手52的远端超远离所述托架1的方向旋转，所述插舌54缩回，所述扩展卡模组与所述计算机壳体脱开连接。
具体的，如图8所示，所述紧固结构551可包括螺纹杆及弹簧。其中，螺纹杆与把手552连接，所述弹簧套设在螺纹杆上，并位于把手552与杠杆扳手之间连接。用户旋转把手，所述螺纹杆就可被旋入托架的螺纹孔中完成连接。即，所述托架上的配合结构可以是与螺纹杆配合的螺纹孔。
下面分别以具体的产品形态为例对本申请上述实施例提供的设计方案进行说明。即下面的实施例将扩展模组限定在了PCIE扩展模组上。一种是采用本申请实施例提供的设计理念设计出的PCIE扩展模组。该PCIE扩展模组与图1所示的结构类容。所述PCIE扩展模组包括：托架1及PCIE扩展电路板。这里的PCIE扩展电路板对应于图1中的第一电路板。其中，托架1上设有连接装置，所述连接装置包括锁紧结构及释放部件31。PCIE扩展电路板设置在所述托架1上，且所述PCIE扩展电路板具有用于电连接所述计算机的电连接结构21以及用于电连接外部设备的电连接端口22。如图2所示，在所述扩展卡模组100自所述计算机壳体6上的安装口61插入后，所述锁紧结构锁紧使得所述 扩展卡模组与所述壳体6内部结构连接，且所述释放部件31及所述电连接端口22外露；所述释放部件31被触发后，所述锁紧结构解锁使得所述扩展卡模组与所述壳体内部结构脱开连接。
可将上文中的第一电路板替换为本实施例中的PCIE扩展电路板即可。PCIE(Peripheral Component Interconnect Express)是一种高速串行计算机扩展总线标准。PCIE属于高速串行点对点双通道高带宽传输，所连接的设备分配独享通道带宽，不共享总线带宽，主要支持主动电源管理，错误报告，端对端的可靠性传输，热插拔以及服务质量(QOS)等功能。PCIE是计算机总线的一个重要分值，它沿用现有的PCI编程概念及信号标准，并且构建了更加高速的串行通信系统标准，且随着计算机技术的发展而不断更新升级，可以支撑的传输速率越来越快。
这里需要说明的是：本实施例对PCIE扩展电路板上的电路设计不作限定，任意可实现PCIE扩展功能的电路均可。只要PCIE扩展电路板的电连接结构及电连接端口为本实施例中提及设计方式即可。另外，本实施例中所述连接装置包括的锁紧结构及释放部件、托架等的结构，可参见上述实施例及附图的内容，此处不作赘述。
另一种是采用本申请实施例提供的设计理念设计出的兼容已有PCIE扩展卡的托架组件。现有PCIE扩展卡(如图3b所示的PCIE扩展卡)安装在本实施例提供的托架组件上便可得到便于拆装的PCIE扩展卡模组，如图3a所示的PCIE扩展卡模组。具体的，本实施例提供的所述托架组件包括：所述托架1及第二电路板8。所述托架1具有第一安装空间，所述第一安装空间用于安装PCIE扩展卡。所述托架上设有所述第二电路板，所述第二电路板上设有连接电路、插座及线缆；所述连接电路分别与所述插座与线缆的一端电连接；所述PCIE扩展卡的插接结构插入所述插座上；所述线缆的另一端用以与计算机电连接；所述托架具有锁紧结构及释放部件；在所述托架自计算机壳体上的安装口插入后，所述锁紧结构锁紧使得所述托架与所述壳体内部结构连接，且所述释放部件及所述PCIE扩展卡的电连接端口外露；所述释放部件被触发后，所述锁紧结构解锁使得所述托架与所述壳体内部结构脱开连接。
这里需要说明的是：本实施例对PCIE扩展卡的具体结构不作限定。另外，本实施例中所述连接装置包括的锁紧结构及释放部件、托架等的结构，可参见上述实施例及附图的内容，此处不作赘述。
图2和图4示出了本申请实施例提供的一种计算机的局部结构示意图。图2和图4，为了方便看到计算机机箱内部的结构，将机箱壳体的一部分可去除了，将机箱内部结构暴露出来。本实施例中的计算机可以是用户使用的台式计算机、也可以是服务器、还可以是数据中心内的服务器集群中的服务器等等，本实施例对此不作限定。具体的，如图2和图4所示，所述计算机包括机箱。机箱具有壳体6，所述壳体6上设有安装口61。所述壳体6内设有与所述安装口61连通的第二安装空间62；以及上述实施例中提供的 所述计算机用扩展模组、或上述实施例提供的所述PCIE扩展模组、或PCIE扩展卡安装在上述实施例提供的所述托架组件后得到的PCIE扩展卡模组。所述计算机用扩展模组、所述PCIE扩展模组或所述PCIE扩展卡模组设置在所述第二安装空间内，并能通过所述安装口拆装。
这里需要说明的是：有关所述计算机用扩展模组、所述PCIE扩展模组或所述PCIE扩展卡模组的具体结构可参见上文中的相应描述，此处不作赘述。
现有通用PCIE扩展卡，如图3b所示的PCIE扩展卡，诞生于PC时代，其设计的方案是将PCIE扩展卡设置在计算机的机箱内。在更换或检修时，需拆计算机的壳体，再对PCIE扩展卡进行更换或检修。对于超大规模数据中心中的计算机(又称服务器)，若大多数计算机都需要拆壳体，势必需浪费很长时间。另外，现有通用PCIE扩展卡，受限于PCIE规范结构形态限制，在计算机(如服务器)中安装，必须通过转接板(如riser转接板)与计算机的主板连接。其不但增加了转接板的物料成本，又因为转接，增加了通信链路中的损耗，无形中增加了高速通信设计的困难度和设计成本。
采用本申请各实施例提供的技术方案实现的计算机(如服务器)具有但不限于如下技术效果：
1、本申请一实施例提供的扩展模组，从计算机上拆装方便。
2、本申请另一实施例还提供了一种兼容现有PCIE扩展卡的方案，即提供了一种托架组件，将现有PCIE扩展卡安装在该托架组件上，即可实现拆装方便的目的。
3、本申请各实施例采用线缆实现扩展模组或PCIE扩展卡与计算机主板的电连接，取消转接板，有助于提升扩展模组的高速信号传输质量，降低转接板对信号传输质量的不利影响。
4、可基于不同高度和宽度PCIE扩展卡，设计相应的托架组件，以兼容各类复杂功能的PCIE扩展卡的安装，以使各类PCIE扩展卡均具有便利的拆卸功能。
进一步的，本申请还一实施例提供一种服务器集群。该服务器集群包括多个服务器。所述多个服务器中的服务器上设有上述实施例提供的所述计算机用扩展模组、或上述实施例提供的所述PCIE扩展模组、或PCIE扩展卡安装在上述实施例提供的所述托架组件后得到的PCIE扩展卡模组。所述多个服务器中的任一服务器通过所述计算机用扩展模组、所述PCIE扩展模组或所述PCIE扩展卡模组，与所述多个服务器中除所述服务器之外的至少一个服务器链接。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
