具体实施方式
为了使本技术领域的人员更好地理解本说明书中的技术方案，下面将结合本说明书实施例中的附图，对本说明书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说明书一部分实施例，而不是全部的实施例。基于本说明书中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本说明书保护的范围。
以下是通过特定的具体实施例来说明本发明实施方式，本领域技术人员可由本说明书所公开的内容了解本发明的优点与效果。本发明可通过其他不同的具体实施例加以施行或应用，本说明书中的各项细节也可基于不同观点与应用，在不悖离本发明的构思下进行各种修改与变更。另外，本发明的附图仅为简单示意说明，并非依实际尺寸的描绘，事先声明。以下的实施方式将进一步详细说明本发明的相关技术内容，但所公开的内容并非用以限制本发明的保护范围。
应当可以理解的是，虽然本文中可能会使用到“第一”、“第二”、“第三”等术语来描述各种组件或者信号，但这些组件或者信号不应受这些术语的限制。这些术语主要是用以区分一组件与另一组件，或者一信号与另一信号。另外，本文中所使用的术语
“或”，应视实际情况可能包括相关联的列出项目中的任一个或者多个的组合。
参照图1所示，本申请实施例公开了一种万向滚珠组件，包括支撑座1和滚珠2，所述支撑座1的一端设置有能形成限位槽的限位部6，所述限位部6用于将所述滚珠2部分地限制在所述限位槽内；所述滚珠2具有伸出所述限位槽的第一侧部和与所述第一侧部相对的第二侧部，所述万向滚珠组件还包括一环形圈3，所述环形圈3设置在所述第二限位槽的第二侧部和所述支撑座1之间。此外，支撑座1的上还设置有用于与板材4连接的连接部5，从 而使其可以通过连接部5被安装于板材4上。虽然如图所示的连接部5位于支撑座1相对远离限位部的一端，但在一些实施例中，连接部也可以位于支撑座1的其他位置，例如相对邻近限位部6的位置，具体结构将在下文中结合其他附图进行阐述。
借由上述结构，通过环形圈3取代了现有设计中的小滚珠，因此，具有环形圈3的万向滚珠组件可以快速安装在金属板材4上，并且保持板材4背面平整。从而使得滑动组件1可以在满足滑动需求的前提下，可以提供较大推出力(正/侧推出力)。例如，可以用于抽屉式机柜或可更换电源模组等之中。
在本实施方式中，所述环形圈3可以由不锈钢材料制成，不锈钢材料即具备一定的强度还可以避免生锈。例如，对于铝，铜，锌合金，尼龙塑料等材料而言，这些材料的硬度不达标，对于铁而言易生锈。因此，本申请人创造性的选取不锈钢材料作为环形圈3的材料。
为了保证滚动顺畅，需要该环形圈3的表面光滑且无异物杂质。在环形圈3成型过程中，一般通过焊接将环形圈3，但为了弥合焊接所带来的焊缝，可以通过震光处理形成无痕O型环。
结合图2和图3所示，在组装时，可以依次将环形圈3和滚珠2放入支撑座1的限位槽中，然后使用专用的压合模具将支撑座1的开口径缩小，此时环形圈3、滚珠2以及支撑座1稳固结合为一个整组件，即完成组装。组装后的万向滚珠组件如图2，实现了快速在薄板上安装，并提供较大推出力和稳定、耐磨滑动功能。
参照图2和图3所示，在加工时，在板材4上开合适大小的孔。将组装后的万向滚珠组件放入安装孔中并采用压合模具进行压铆安装。安装后支撑座1紧紧结合在板材4上，滚珠2活动顺畅，且板材4背面保持平整不会与其他零件有干涉风险。如图所示，支撑座1相对邻近滚珠2的第二侧的表面为水平表面，并且其与板材4的一侧大体齐平，所示环形圈3被布置于在水平面上，以形成对滚珠2的良好支撑。
图4至图7示出了四种万向滚珠组件通过压铆或者翻铆固定在板材4上的四种不同的板材4系统。在连接后，所述连接部5可以呈台阶状，也可以根据需要呈坡面状。其中，箭头方向为板材4的装入方向。
优选地，所述支撑座1背离所述滚珠2的一侧端面与所述板材4背离所述滚珠2的一侧端面齐平。
图8示出了根据本申请另一实施例的万向滚珠组件的示意图。如图所示，支撑座1在邻近滚珠2的第二侧部的表面上设置有凹陷部7，环形圈3被布置于凹陷部7之中。凹陷部7的形状和尺寸可以被构造为阻止环形圈3在凹陷部7内发生运动。例如，凹陷部7可以被构造为环形圈3的外切多变形状的凹陷部，或者与环形圈形状大体匹配的圆形凹陷部。虽然如 图所示的凹陷部的深度与环形圈3的截面直径d1大体相当，但是在一些实施例中，凹陷部的深度也可以被设置为小于d1，从而尽量避免与滚珠2或其他部件发生干涉。
滚珠组件的环形圈3和滚珠的尺寸可以进一步设置，以保证滚珠组件的滚动能力和稳定性。当环形圈为O型环时，如图8所示，并且所述O型环的内径d2被设置为：
其中所述K为常数，并且所述K大于0。
优选地，在一些实施例中，常数K的数值范围为d1的四分之一至d1的两倍。
图9示出了根据本申请另一实施例的万向滚珠组件的示意图。如图所示，其支撑座1在邻近滚珠的第二侧部的一端设置有封闭端盖8，该封闭端盖8与支撑座1的主体之间固定连接。一些实施例中，封闭端盖8通过其连接段9与支撑座1的主体之间可拆卸地连接，例如，封闭端盖8的连接段9的外表面设置有外螺纹，其与支撑座1的主体上的相应位置的内螺纹匹配以实现螺纹连接。当然，一些实施例中，封闭端盖8与支撑座1的主体之间也可以采用压铆连接。
需要说明的是，图9所示结构的万向滚珠组件的组装过程可以更为简易，以进一步提高生产效率。具体地，不同于以上对于图2和3所示组装方法的描述，其限位槽部分可以预先成形，随后可以依次将环形圈3和滚珠2放入支撑座1的限位槽中，然后在将封闭端盖连接至支撑座1，从而完成整体组装。
图10示出了根据本申请再一实施例的万向滚珠组件的示意图。如图所示，其连接部5位于所述支撑座相对邻近限位部6的位置，从而在板材4的上方空间有效或对最终滚珠高度有效的情况下，在有效实现较低高度的同时而不影响滚动性能。如图所示，在这种构造下，支撑座1背离滚珠2的一侧端面突出于板材4背离滚珠2的一侧端面。
以上所公开的内容仅为本发明的优选可行实施例，并非因此局限本发明的申请专利范围，所以凡是运用本发明说明书及图式内容所做的等效技术变化，均包含于本发明的申请专利范围内。
本说明书中的各个实施例采用递进的方式描述，各个实施例之间相同或相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。虽然通过实施例描绘了本申请，本领域普通技术人员知道，本申请有许多变形和变化而不脱离本申请的精神，
希望所附的实施方式包括这些变形和变化而不脱离本申请。
