Description

一种转接卡、扩展卡组件及服务器
本申请要求于2018年12月24日提交中国专利局、申请号为201811585012.X、发明名称为“一种转接卡、扩展卡组件及服务器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及计算机硬件技术领域，更具体地说，涉及一种转接卡。此外，本发明还涉及一种包括上述转接卡的扩展卡组件及包括该扩展卡组件的服务器。
背景技术
随着人工智能(AI)技术以及超级计算技术的高速发展，服务器对于GPU的需求越来越大，服务器单体中需要越来越多数量的GPU卡进行大量计算，因此，服务器单体中GPU卡的密度越来越高。
现有技术中，标准单组GPU卡通常通过一个转接卡与主板对接，多个标准单组GPU卡和转接卡组合后在服务器内部沿服务器的宽度方向按顺序排列设置。
然而，受数据中心标准机柜的外框结构尺寸规范限制，服务器的内部空间有限，采用现有技术中的GPU卡设置方式将无法充分利用服务器的内部空间，一方面造成服务器部分内部空间结构的浪费，另一方面导致服务器无法支持更多数量的GPU卡。
综上所述，如何优化服务器的内部空间，使服务器能够在有限的内部空间内支持更多数量的GPU卡，是目前本领域技术人员亟待解决的问题。
发明内容
有鉴于此，本发明的目的是提供一种转接卡，体积小，结构紧凑，可应用于服务器。
本发明的另一目的是提供一种包括上述转接卡的扩展卡组件，其结构 紧凑，占用空间小。
本发明的又一目的是提供一种包括上述扩展卡组件的服务器，可在有限的结构空间内支持更多的扩展卡，提高服务器单体的密度和性能。
为了实现上述目的，本发明提供如下技术方案：
一种转接卡，包括相对设置的两个转接板，两个所述转接板的相对侧分别设有至少一个用于插设扩展卡的插槽，两个所述转接板上的所述插槽错开设置，且所有所述插槽在垂直于所述转接板的平面内的投影至少部分重叠，两个所述转接板分别设有用于使对侧所述转接板上的各所述插槽裸露的让位部。
优选地，两个所述转接板上下错开设置，且两个所述转接板中一者最顶端的所述插槽裸露、另一者最低端的所述插槽裸露。
优选地，两个所述转接板沿高度方向的中心线共面，且两个所述转接板中一者最顶端及其最低端的所述插槽均裸露。
优选地，同一所述转接板上相邻两个所述插槽之间设有用于方便插拔扩展卡的间隔。
优选地，所有所述插槽均为PCIE插槽。
优选地，两个所述转接板均设有用于与服务器的主板对接的高密连接器。
一种扩展卡组件，包括上述任意一种转接卡，还包括分别与所述转接卡的两个转接板上的插槽对应插接的扩展卡。
优选地，插设于不同所述转接板上的所述扩展卡的零件面背向设置。
优选地，插设于同一所述转接板上的所有所述扩展卡平行设置。
一种服务器，包括服务器本体，所述服务器本体内设有至少一组上述任意一种扩展卡组件。
本发明提供的转接卡，由于两个转接板上的插槽相对错开设置，同时，所有插槽在垂直于转接板的平面内的投影至少部分重叠，也即，两个转接板上的所有插槽沿垂直于转接板的方向至少共用部分宽度空间，这可以减小两个转接板之间的距离，因此，减小了转接卡整体所占用的空间。
也即，相比于现有技术中的两个标准单体转接卡来说，减小了两个转接板上的插槽整体所占用的宽度空间，当两个转接板上的所有插槽在垂直 于转接板的平面内的投影完全重叠时，可节省一个插槽的宽度空间，进而可以最大程度的减小两个转接板之间的距离，使转接卡的结构紧凑，体积小。当将该转接卡应用于服务器时，可节约服务器的内部空间。
本发明提供的扩展卡组件，包括上述转接卡，因此，其结构紧凑，占用空间小，可应用于服务器内部，以合理化利用服务器的内部空间。
本发明提供的服务器，包括至少一组上述扩展卡组件，由于扩展卡组件相比于现有技术占用空间小，因此，可使服务器在有限的结构空间内放置更多的外插卡，提高了服务器单体的密度和性能。
附图说明

图5为图4的正视图；
图6为图4的俯视图。
图1至图6中的附图标记如下：
1为转接板、11为插槽、12为让位部、13为高密连接器、2为扩展卡。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通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，都属于本发明保护的范围。
本发明的核心是提供一种转接卡，体积小，结构紧凑。本发明的另一核心是提供一种包括上述转接卡的扩展卡组件，其结构紧凑，占用空间小。本发明的又一核心是提供一种包括上述扩展卡组件的服务器，可在有限的结构空间内支持更多的扩展卡，提高服务器单体的密度和性能。
请参考图1-图3，图1为本发明所提供的转接卡具体实施例的结构示意图；图2为图1的左视图；图3为图1的俯视图。
本发明提供一种转接卡，可应用于服务器内，以合理利用服务器的内部空间。该转接卡包括两个相对设置的转接板1，分别为第一转接板1和第二转接板1，两个转接板1相对的一侧分别设有用于插设扩展卡2的插槽11，且每个转接板1上设置的插槽11的数量均为至少一个，也即，第一转接板1朝向第二转接板1的一侧设有至少一个第一插槽11，第二转接板1朝向第一转接板1的一侧设有至少一个第二插槽11，两个转接板1上的插槽11错开设置，且所有插槽11在垂直于转接板1的平面内的投影至少部分重叠。
相应地，两个转接板1分别设有用于使对侧转接板1上的各插槽11裸露的让位部12。也就是说，第一转接板1上对应第二插槽11的位置设有用于让位插设于第二插槽11的扩展卡2的第一让位部12；第二转接板1上对应第一插槽11的位置设有用于让位插设于第一插槽11的扩展卡2的第二让位部12。
具体地，当第二插槽11对应第一转接板1的中间部时，第一让位部12为设于第一转接板1的中间部的第一让位孔；当第二插槽11对应第一转接板1的顶部和/或底部时，第一让位部12为设于第一转接板1的顶部和/或底部的第一让位缺口。
同理，当第一插槽11对应第二转接板1的中间部时，第二让位部12为设于第二转接板1的中间部的第二让位孔；当第一插槽11对应第二转接板1的顶部和/或底部时，第二让位部12为设于第二转接板1的顶部和/或底部的第二让位缺口。
为了描述方便，第一让位部12和第二让位部12统称为让位部12，也即，本发明通过在转接板1上设置让位部12来使对面转接板1上的插槽11裸露，以便于扩展卡2的插拔，换句话说，本发明通过在转接板1上设 置让位部12来避让用于插设于对面转接板1的插槽11内的扩展卡2，以避免干涉扩展卡2插拔。
优选地，让位部12为用于与其所供穿设的扩展卡2的插接端相配合的让位部12。也即，让位部12的形状及尺寸分别与穿设于该让位部12的扩展卡2的插接端相适配。
可以理解的是，本发明提供的转接卡，由于两个转接板1上的插槽11相对错开设置，同时，所有插槽11在垂直于转接板1的平面内的投影至少部分重叠，也即，两个转接板1上的所有插槽11沿垂直于转接板1的方向至少共用部分宽度空间，这可以减小两个转接板1之间的距离，因此，减小了转接卡整体所占用的空间。
也即，相比于现有技术中的两个标准单体转接卡来说，减小了两个转接板1上的插槽11整体所占用的宽度空间，当两个转接板1上的所有插槽11在垂直于转接板1的平面内的投影完全重叠时，可节省一个插槽11的宽度空间，进而可以最大程度的减小两个转接板1之间的距离，使转接卡的结构紧凑，体积小。
需要说明的是，两个转接板1上的插槽11在投影面上的投影可以部分重叠，优选为完全重叠。也即，第一插槽11和第二插槽11在投影面上的投影重叠的面积越大，则两个转接板1之间的距离越小，转接卡整体所占用的空间越小。投影面指垂直于转接板1的平面。
可以理解的是，为了防止两个转接板1上的插槽11相互干涉，两个转接板1上的插槽11错开设置。
本发明对两个转接板1上的插槽11的排布方式不做限定。例如，第一插槽11和第二插槽11可以一一间隔设置，当然，也可以是任意相邻两个第一插槽11之间设有至少两个第二插槽11。
需要说明的是，本文中的宽度方向是垂直于转接板1的方向。
另外，本发明中两个转接板1上的插槽11的规格可以相同，也可以不同。
为了减少转接板1上让位部12的数量，以便于加工及提高转接板1的强度，在上述实施例的基础之上，两个转接板1上下错开设置，且两个转接板1中一者最顶端的插槽11裸露、另一者最低端的插槽11裸露。
优选地，第一转接板1和第二转接板1上下错开设置，第一转接板1最上端的第一插槽11的底部高度高于第二转接板1的顶端高度；第二转接板1最下端的第二插槽11的顶部高度低于第一转接板1的低端高度。
也即，本实施例通过合理布置两个转接板1的位置关系，来让位插入最顶端插槽11以及最低端插槽11内的扩展卡2，而不必为最顶端插槽11和最低端插槽11专门开设让位部12。因此，简化了结构，节省了加工工艺，便于加工，且通过减少让位部12的数量提高了转接板1的结构强度。
在另一种实施例中，两个转接板1沿高度方向的中心线共面，且两个转接板1中一者最顶端及其最低端的插槽11均裸露。
优选地，第一转接板1的高度大于第二转接板1的高度，第一转接板1沿高度方向的中心线与第二转接板1沿高度方向的中心线共面；第一转接板1最上端的第一插槽11的底部高度高于第二转接板1的顶端高度，第一转接板1最下端的第一插槽11的顶部高度低于第二转接板1的低端高度。
也即，本实施例通过两个转接板1的尺寸差来使其中一个转接板1上最顶端及其最低端的插槽11裸露。
当然，还可以是这种情况，两个转接板1的底端平齐，其中一个转接板1的顶端低于另一转接板1的顶端，以使另一转接板1最上端的插槽11裸露。
考虑到转接卡使用的方便性，在上述任一项实施例的基础之上，同一转接板1上相邻两个插槽11之间设有用于方便插拔扩展卡2的间隔。
也就是说，任意相邻的两个第一插槽11之间、以及任意相邻的两个第二插槽11之间均设有合适的间隔，以方便插入相邻两个第一插槽11或第二插槽11中的扩展卡2的插拔，提高使用方便性。
考虑到插槽11的通用性，在上述实施例的基础之上，所有插槽11均为PCIE插槽。
可以理解的是，显卡会用到PCIE插槽；独立声卡、独立网卡、USB 3.0/3.1接口扩展卡2、RAID阵列卡、PCI-E SSD、mSATA SSD、m.2 SSD、M.2无线网卡或者其它M.2接口设备等硬件都可以插到PCIE插槽上，因此，本实施例中的各PCIE插槽可确保转接卡的扩展能力，满足用户的不同需 求。
考虑到各扩展卡2通过转接卡连接到服务器主板上的方便性，在上述实施例的基础之上，两个转接板1均设有用于与服务器的主板对接的高密连接器13。
请参考图4-图6，图4为本发明所提供的扩展卡组件具体实施例的结构示意图；图5为图4的正视图；图6为图4的俯视图。
除了上述转接卡，本发明还提供一种包括上述实施例公开的转接卡的扩展卡组件，该扩展卡组件还包括分别与转接卡的两个转接板1上的插槽11对应插接的扩展卡2。
为了描述方便，扩展卡2包括第一扩展卡2和第二扩展卡2，第一扩展卡2穿设于第二让位部12并与第二插槽11配合插接；第二扩展卡2穿设于第一让位部12并与第一插槽11配合插接。
也即，本实施例将各扩展卡2插入上述转接卡的各插槽11中，形成扩展卡组件。
需要说明的是，本发明对扩展卡2不做具体限定，扩展卡2可以为GPU卡，也可以为其它金手指形式的外插卡；只要扩展卡2能够与转接卡上的各插槽11配合插接即可。
考虑到扩展卡2插拔的方便性及扩展卡组件所占用的整体空间，在上述实施例的基础之上，插设于同一转接板1上的所有扩展卡2平行设置。
优选地，插设于同一转接板1上的所有扩展卡2与转接板1所在平面垂直设置。当然，插设于同一转接板1上的所有扩展卡2也可以倾斜设置，与转接板1具有一定的夹角，具体可以根据所适用的空间需求来设置。
在上述实施例的基础之上，插设于不同转接卡上的扩展卡2的零件面背向设置。
也即，插设于不同转接卡上的扩展卡2的零件面的方向刚好相反，例如，如图6所示，第一扩展卡2的零件面朝上，第二扩展卡2的零件面朝下。
除了上述扩展卡组件，本发明还提供一种包括上述实施例公开的扩展卡组件的服务器，该服务器的其他各部分的结构请参考现有技术，本文不再赘述。
可以理解的是，19寸标准机柜内的宽度尺寸为450mm，通用机架式服务器使用滚珠滑轨支持服务器单体从机柜内部拉出，以便于打开服务器上盖维护服务器内部部件。目前标准滚珠滑轨厚度最薄为6.9mm，承重40KG，按照最薄滑轨标准，机柜内宽度减去服务器左右两侧的滑轨厚度尺寸，即得服务器框体外宽最大尺寸为436.2mm。服务器框体外宽尺寸减去机箱外壳左右两侧的钣金厚度(1.2mm*2)，最终得服务器内部实际可应用的最大尺寸为433.8mm。
而现有技术中标准单组GPU和标准单体转接卡组合后的宽度尺寸为116.4mm，因此，若按116.4mm的宽度尺寸在服务器内部顺序排列标准单组GPU和标准单体转接卡的组合，只能在433.8mm空间内横向排列三组GPU卡和标准单体转接卡组合，也即，服务器内部剩余宽度空间不足以设置第四组GPU卡和标准单体转接卡组合，造成服务器内部剩余宽度空间的浪费，同时，也限制了GPU卡的设置数量。
然而，若采用本发明提供的扩展卡组件，即两张GPU卡使用一个转接卡，转接卡优选通过高密连接器13同主板对接，转接卡两个转接板1上的PCIE插槽沿上下方向相互错开，但在机箱宽度方向上，从顶视图或俯视图看，两个转接板1的PCIE插槽是至少部分重叠的。也即，两个转接板1上的插槽11至少共用部分同一宽度空间，使分别插设于两个转接板1上的扩展卡2的插接部交错设置，节省了一个插槽11的空间。
具体地，本发明的扩展卡组件中两张GPU卡和两张转接板1组合后的整体宽度尺寸为215.05mm，因此，可在内部宽度空间为433.8mm的服务器内并排设置两组该扩展卡组件，即四张扩展卡2，实现1U空间内支持平铺四张GPU卡，同理，可实现2U服务器空间内支持八张GPU卡。
因此，相比于现有技术中两个标准单组GPU和标准单体转接卡组合后的宽度尺寸，本发明所提供的扩展卡组件减少了转接卡和插槽11所占用的整体宽度空间。在最大化利用服务器内部空间的同时，增大了扩展卡2的数量，从而使服务器有限的结构空间内可放置更多的外插卡，提高了服务器单体的密度和性能。
还需要说明的是，在本说明书中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要 求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。术语“上下”、“左右”、“横向”、“宽度”、“顶端”、“底端”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以及特定的方位构造和操作，因此不能理解为对本申请的限制。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
以上对本发明所提供的转接卡、扩展卡组件及服务器进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
