Description

一种多节点安全锁定装置及服务器
本申请要求在2021年5月28日提交中国专利局、申请号为202110592204.9、发明名称为“一种多节点安全锁定装置及服务器”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
本申请涉及服务器技术领域，更进一步涉及一种多节点安全锁定装置及服务器。
背景技术
服务器内部通常安装至少两个节点模块，每个节点模块可以从服务器中抽出，当两个或以上节点模块同时抽出时，造成服务器的重心偏移，重心移至服务器外壳之外，容易导致服务器倾斜掉落。
因此在操作时，需要操作人员时间注意不要同时抽出两个节点模块，但人为操作难以保证不出现错误，因此服务器倾倒的问题时有发生，特别是在实验室中进行测试时，服务器未安装于服务器机架上，倾倒现象更容易发生。
目前在家具领域，为了防止两个抽屉同时被抽出，也设置了相应的锁定结构，现有的防止抽屉同时抽出来的结构方案占用了前端两侧的空间。但对于横向阵列服务器节点前端空间以及节点左右两侧空间受限的系统构架下，例如1U或者2U高度的机箱，侧边被滑轨占用，不能使用现有的技术方案。再者，服务器节点的内部模组存在需要从侧面维护的场景，服务器节点侧边的空间不能被联动互锁结构或者滑轨占用，否则会影响节点模组内侧维护。
对于本领域的技术人员来说，如何在不占用节点模块前端两侧空间的情况下，保证节点模块无法同时被抽出，是目前需要解决的技术问题。

具体实施方式
本申请的核心在于提供一种多节点安全锁定装置，在不占用节点模块前端两侧空间的情况下，当一个节点模块抽出时，防止其他对应的节点模块抽出，降低服务器倾倒的风险。
为了使本领域的技术人员更好地理解本申请的技术方案，下面将结合附图及具体的实施方式，对本申请的多节点安全锁定装置进行详细的介绍说明。
本申请提供一种多节点安全锁定装置，该装置包括导向轨1、锁定杆2和导向板3，导向轨1设置在机箱上，锁定杆2限位安装在导向轨1上，锁定杆2相对于导向轨1滑动，锁定杆2垂直于节点模块的移动方向平移。
导向板3安装在节点模块上，导向板3与节点模块同步移动，导向板3上设置若干个导向槽31，锁定杆2上凸出设置若干个限位柱21，每个限位柱21可对应插入一个导向槽31中，限位柱21和导向槽31相互配合移动，限位柱21能够相对于导向槽31沿导向路径移动；需要注意的是，限位柱21随锁定杆2做直线移动，导向槽31随导向板3做直线移动，锁定杆2和导向板3的运动方向大致相互垂直，但限位柱21相对于导向槽31沿其导向路径做复合运动。
当一个节点模块被抽出时，导向槽31的侧边对限位柱21施加作用力，使锁定杆2平移到锁定位置，由其他的限位柱21阻挡其他的节点模块被抽出。导向板3与对应的限位柱21从导向槽31的缺口处分离，当限位柱21到达导向槽31的缺口处时，节点模块可以完全被抽出。
当节点模块被向内推回时，其对应的限位柱21从导向槽31的缺口处进入，导向槽31的侧壁推动限位柱21，导向槽31使锁定杆2平移到解锁位置。
本申请在每个节点模块上分别设置独立的导向板3，每个导向板3上设置有导向槽31，由于锁定杆2无法沿节点模块的运动方向移动，当锁定杆2位于锁定位置时，限位柱21与导向槽31的侧壁相互配合限位，此时向外拉动节点模块时被对应的限位柱21阻挡，该节点模块无法被抽出。
当锁定杆2位于解锁位置时，此时所有的导向板3不受限位柱21的阻挡，任意一个节点模块可以被抽出，当某一个节点模块被抽出时，带动锁定杆2重新移动到锁定位置。
该锁定杆2可以对应匹配两个或以上数量的节点模块，确保操作时一次只允许抽出一个节点模块，其他的节点模块无法被抽出，该装置不占用节点模块前端两侧空间，防止重心偏移发生危险。
结合图1A所示，为多节点安全锁定装置与机箱相互装配的结构图，图中A表示机箱，B表示节点模块，节点模块沿图中双箭头所示方向移动；图1B为图1A内端部分的局部放大图。导向轨1的长度方 向沿X轴方向，节点模块沿Y轴方向移动。
本方案中的导向槽31优选为垂直于导向板3板面贯通设置的开孔，此开孔形成导向路径，导向槽31为不封闭式的开孔，其中一侧与外界连通；采用开孔的形式方便加工，除了开孔的形式之外，还可以在导向板3的板面上凸出设置导向块形成导向路径。
导向槽31由分别位于两侧并相对凸出设置的止挡块32和导向斜块33形成，结合图1B所示，导向槽31相当于在矩形孔的相对两个侧壁上凸出设置止挡块32和导向斜块33，导向槽31整体近似“S”字形结构。
止挡块32和导向斜块33在节点模块的移动方向上的投影具有重叠部分，也即图中Y轴方向上的投影具有重叠部分，止挡块32相对于导向斜块33更靠外侧。
止挡块32包括阻挡边321和解锁导向边322，阻挡边321平行于锁定杆2的平移方向，解锁导向边322和阻挡边321形成锐角；止挡块32的外形呈三角形，阻挡边321与导向槽31最靠外侧(OUTER)的边之间具有间距，可容纳限位柱21；当限位柱21与此阻挡边321接触时，向外拉动节点模块时受到限位柱21的阻挡，无法被拉出，实现锁定效果。
导向斜块33包括上锁导向边331，上锁导向边331与阻挡边321形成锐角，上锁导向边331朝向内侧(INNER)倾斜，当节点模块向外拉出时，限位柱21与上锁导向边331接触，由于上锁导向边331倾斜设置，可以推动锁定杆2向锁定位置移动。
相应地，当拉出的节点模块被推回时，限位柱21与解锁导向边322接触，解锁导向边322和上锁导向边331大体平行，解锁导向边322推动锁定杆2向解锁位置移动。
结合图2A所示，为被向外抽出的节点模块所对应的限位柱21相对于导向槽31的移动路径；当节点模块向外抽出时，节点模块沿Y轴方向移动，此时限位柱21按箭头Ⅰ方向移动，接触导向斜块33的上锁导向边331，沿上锁导向边331按箭头Ⅱ方向移动，最后按箭头 Ⅲ方向移动，此时节点模块与锁定杆2相互分离，锁定杆2因上锁导向边331沿导向轨1在实际空间中完成了从左向右平移。
如图2B所示，为未被抽出的节点模块锁定过程所对应的限位柱21相对于导向槽31的移动路径，限位柱21相对于未被抽出的导向板3向右沿箭头Ⅳ平移，最终到达图2C所示的位置；图2C为未被抽出的节点模块所对应的限位柱21受到止挡块32阻挡的结构示意图。
由于节点模块被抽出时沿Y轴方向做直线运动，限位柱21只能沿X轴方向做直线运动，因此当抽出的节点模块沿箭头Ⅱ方向移动时，推动锁定杆2沿X轴移动，其他的限位柱21沿箭头Ⅳ移动，到达图2C所示的位置。限位柱21对止挡块32的阻挡边321接触产生阻挡，此时未被抽出的节点模块无法沿Y轴方向被抽出。
如图3A所示，为抽出的节点模块向内移动时所对应的限位柱21相对于导向槽31的移动路径；节点模块带动导向板3沿Y轴方向移动，限位柱21沿箭头Ⅰ移动接触止挡块32的解锁导向边322，沿解锁导向边322按箭头Ⅱ移动。
如图3B所示，为未被抽出的节点模块解锁过程所对应的限位柱21相对于导向槽31的移动路径；限位柱21和锁定杆2沿箭头Ⅲ所示的方向移动，到达解锁位置后全部的导向板3均不受到限位柱21的阻挡，任意一个节点模块可以被抽出。
导向斜块33还包括复位导向边332，复位导向边332在导向槽31的缺口处形成喇叭口，复位导向边332和上锁导向边331之间形成锐角，也即整个导向斜块33呈锐角三角形，由于形成了哈喇口结构，当限位柱21沿图3A中的箭头Ⅰ移入导向槽31时具有更大的容错空间，若限位柱21与复位导向边332接触时也可以保证正常进入。
结合图4A和图4B所示，图4B表示将联动互锁杆锁定杆2中中部切剖矩形孔的示意结构；导向轨1上设置阻尼弹片11，阻尼弹片11在竖向上具有弹力，可以被向下按压或者向上回弹，在不受外力的作用下，阻尼弹片11因弹力向上顶出；锁定杆2上设置两个阻尼孔22，两个阻尼孔22沿锁定杆2的长度方向设置，阻尼弹片11具有球面形 的凸起，阻尼弹片11上的球形凸起可分别卡入阻尼孔22实现弹性限位；当锁定杆2平移至解锁位置或锁定位置时，阻尼弹片11分别与其中一个阻尼孔22弹性限位。
结合图4A，当一个节点模块被抽出时，带动锁定杆2朝向右下方移动，阻尼弹片11卡入左侧标注LOCK的阻尼孔22；当该节点模块被推回时，带动锁定杆2朝向左上方移动，阻尼弹片11卡入右侧标注UNLOCK的阻尼孔22。当锁定杆2在解锁位置和锁定位置之间的范围移动时，阻尼弹片11被下压与锁定杆2的下表面接触。
通过设置阻尼孔22和阻尼弹片11，当到达解锁位置或锁定位置时产生明确的反馈，并且从解锁位置或锁定位置向另一位置移动时需要克服较大的阻力，防止意外出现解锁或锁定。
具体地，如图1B所示，导向板3横向凸出设置在节点模块的内端部；除此之外，导向板3还可设置在节点模块的下方。
在上述任一技术方案及其相互组合的基础上，本申请还包括解锁连杆4，解锁连杆4的延伸方向与节点模块的移动方向平行，解锁连杆4可沿长度方向移动；解锁连杆4的内伸端设置解锁斜边41，解锁斜边41处的宽度大于解锁连杆4中间主体部分的宽度，当解锁连杆4沿解锁方向移动时，解锁斜边41带动锁定杆2从锁定位置移动到解锁位置。通过解锁连杆4可以独立地将锁定杆2移动到解锁状态，从而解除对其他节点模块的锁定，在需要的情况下，可以操作解锁连杆4解锁其他的节点模块。
具体地，解锁方向平行于节点模块移动方向，解锁连杆4的外伸端转动连接解锁把手42，转动解锁把手42时能够带动解锁连杆4与节点模块平行的方向向外移动实现解锁。
如图4A所示，为解锁连杆4的结构示意图；图4B为解锁连杆4推动锁定杆2的过程示意图。解锁连杆4的长度方向与节点模块的移动方向平行，先沿弯箭头①转动解锁把手42，解锁连杆4同步沿箭头②移动，通过解锁斜边41带动锁定杆2沿箭头③移动，推动锁定杆2解锁。
本申请还提供一种服务器，包括上述的多节点安全锁定装置，该服务器能够实现相同的技术效果。
