技术领域
本申请属于电子产品技术领域，具体涉及一种转轴机构和电子设备。
背景技术
随着电子设备行业的快速发展，人们对电子设备的需求不断提高。为了追求更好的用户体验，电子设备正朝着大屏显示发展，为兼顾其便携性，折叠屏电子设备成为当前的主流。市面上的折叠屏电子设备主要分为左右折叠和上下折叠两大类，两者原理类似，即通过手动控制两侧机身开合，并通过转轴机构控制两侧机身开合角度一致。
在常规的转轴机构设计形式中，底座和摆臂压盖通过锁螺丝固定，并且二者之间形成滑槽，虚拟摆臂的轴瓦沿着滑槽转动，使得虚拟摆臂可以绕着转轴机构的中心转动，最终实现折叠屏电子设备的开合。但此种设置方式在电子设备处于折叠状态时，电子设备的两侧机身较容易出现较大的搓动现象，即第一机身和第二机身较容易在垂直于转轴，且平行于第一机身和第二机身的延伸方向的方向上发生错位，其原因在于滑槽对轴瓦的约束性较差，即滑槽尺寸精度较差，而滑槽尺寸精度容易受底座、摆臂压盖和虚拟摆臂的制造公差的影响以及底座和摆臂压盖的装配公差的影响，进而容易使电子设备的两侧机身出现较大的搓动现象，进而影响用户的使用体验。
综上，相关技术涉及的转轴机构的滑槽存在尺寸精度较差的问题。
发明内容
本申请实施例的目的是提供一种转轴机构和电子设备，能够解决相关技术涉及的转轴机构的滑槽存在尺寸精度较差的问题。
本申请实施例提供一种转轴机构，用于转动连接电子设备的第一机身和第二机身，所述转轴机构包括摆臂、摆臂压盖和底座，所述摆臂压盖与所述底座相连，所述摆臂的第一端与所述第一机身或所述第二机身相连，所述摆臂的第二端设有轴瓦，所述摆臂压盖上开设有滑槽，所述轴瓦可滑动地设于所述滑槽中。
本申请实施例提供一种电子设备，包括上文所述的转轴机构、所述第一机身和所述第二机身，所述第一机身和所述第二机身通过所述转轴机构转动连接。
本申请实施例中，由于摆臂压盖本身开设有滑槽，且摆臂的轴瓦滑动地设于滑槽中，由此可知，滑槽的尺寸精度不再受底座的制造公差的影响以及底座和摆臂压盖的装配公差的影响，这在一定程度上使得滑槽的尺寸精度更高，从而使得滑槽对轴瓦的约束性较好，进而使得电子设备处于折叠状态时，第一机身和第二机身较不容易出现较大的搓动现象，进而提升用户的使用体验。

具体实施方式
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地描述，显然，所描述的实施例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，本领域普通技术人员获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例公开的转轴机构进行详细地说明。
请参考图1-图7，本申请公开了一种转轴机构，所公开的转轴机构包括摆臂200、摆臂压盖300和底座400。
转轴机构用于转动连接电子设备的第一机身110和第二机身120，通过转轴机构可使得电子设备的第一机身110的至少部分和第二机身120的至少部分相互靠近或相互远离，以实现电子设备的折叠功能或展开功能。
摆臂200是电子设备实现折叠功能和展开功能的主要部件，摆臂200的第一端与第一机身110或第二机身120相连，此种设置方式使得摆臂200可以与第一机身110或第二机身120同步运动，即当用户折叠或展开电子设备时，摆臂200可跟随第一机身110或第二机身120绕摆臂200的转动轴线旋转，以实现电子设备的折叠或展开。
摆臂压盖300用于保护摆臂200的至少部分，具体地，摆臂压盖300上开设有滑槽310，摆臂200的第二端设有轴瓦210，轴瓦210可滑动地设于该滑槽310中，即轴瓦210与该滑槽310滑动配合，第一机身110或第二机身120相对于转轴机构发生转动时，轴瓦210沿着该滑槽310转动。
底座400是转轴机构的基础部件，其可以为转轴机构的其他部件提供安装基础，具体地，摆臂压盖300与底座400相连，可选地，底座400可以为长条形的非晶材料结构件。
本申请实施例中，由于摆臂压盖300本身开设有滑槽310，且摆臂200的轴瓦210滑动地设于滑槽310中，由此可知，滑槽310的尺寸精度不再受底座400的制造公差的影响以及底座400和摆臂压盖300的装配公差的影响，这在一定程度上使得滑槽310的尺寸精度更高，从而使得滑槽310对轴瓦210的约束性较好，进而使得电子设备处于折叠状态时，第一机身110和第二机身120较不容易出现较大的搓动现象，进而提升用户的使用体验。
可选地，摆臂压盖300包括一体设置的压盖本体320和延伸部330，即在制成摆臂压盖300的过程中，压盖本体320和延伸部330为一体成型，且延伸部330的两端均与压盖本体320相连，延伸部330和压盖本体320之间 形成供轴瓦210滑动的滑槽310。一体成型的压盖本体320和延伸部330使得摆臂压盖300具有较大的结构强度，但此种设置方式使得摆臂压盖200的重量较重以及较不容易成型滑槽310。
另一种实施例中，延伸部330的一端与压盖本体320相连，延伸部330的另一端为自由端，延伸部330和压盖本体320之间形成供轴瓦210滑动的滑槽310。由此可知，仅在延伸部330一端与压盖本体320相连的情况下，就可形成滑槽310，这使得延伸部330的制成材料较少，进而使得摆臂压盖200的重量较轻，且在此种设置方式下，在制成摆臂压盖300时，较容易在压盖本体320和延伸部330之间形成滑槽310，即形成滑槽310的模具较容易从摆臂压盖300上取出，且更便于操作人员操作。
可选地，延伸部330的数量可以为一个，为确保轴瓦210在滑槽310内可以更加稳定地滑动，滑槽310与轴瓦210的接触面积需要设置得较大一些，即延伸部330需要与轴瓦210的接触面积较大，但这会使得延伸部330的尺寸较大，进而使得摆臂压盖300的物料成本较高。
为降低成本，在另一种实施例中，延伸部330的数量为至少两个，其中包括第一延伸部331和第二延伸部332，第一延伸部331和第二延伸部332沿摆臂200的转动轴线所在方向间隔排布，轴瓦210沿摆臂200的转动轴线所在方向的两端分别与第一延伸部331和第二延伸部332滑动配合，即轴瓦210的两端均能与滑槽310接触，且轴瓦210受到的滑槽310的支撑力比较平衡，这使得轴瓦210在滑槽310内转动的更加稳定、可靠。由于轴瓦210的两端均与滑槽310接触，因此，在确保接触稳定性的前提下，第一延伸部331和第二延伸部332的尺寸可以设计的较小些，进而使得摆臂压盖300的物料成本有所降低。
可选地，第一延伸部331的自由端和第二延伸部332的自由端相背设置，此时，在成型滑槽310和压盖本体320之后取出模具时，先将成型压盖本体320的模具取出，再将成型第一延伸部331和压盖本体320形成的滑槽310 的模具和成型第二延伸部332和压盖本体320形成的滑槽310的模具，即两个模具沿滑槽310的轴向，且相反方向上直接取出，由此可知，此种设置方式使得滑槽310的模具更容易取出，且操作速度快，操作步骤简单，省时省力。在该实施例中，由于第一延伸部331的自由端和第二延伸部332的自由端相背设置，即形成的两个滑槽310相背设置，此时，可以将两个滑槽310之间的距离设置的较短一些，进而摆臂压盖300的尺寸也可以较短一些。
可选地，由于轴瓦210设在摆臂压盖300的滑槽310中，为使摆臂压盖300和底座400相连，转轴机构还包括连接件500，连接件500用于连接摆臂压盖300和底座400，但由于轴瓦210具有一定的尺寸，因此，滑槽310占用的摆臂压盖300的空间较多，这使得底座400和摆臂压盖300之间可通过连接件500连接的空间较少，即底座400和摆臂压盖300仅可以在远离轴瓦210处通过连接件500相连，这可能使底座400和摆臂压盖300的连接稳定性较差。
为提升连接稳定性，在另一种实施例中，轴瓦210开设有第一避让口211，第一避让口211位于第一延伸部331和第二延伸部332之间，底座400通过连接件500与摆臂压盖300相连，且连接件500的至少部分位于第一避让口211内。通过此种设置方式使得底座400和摆臂压盖300可连接的空间增多，进而增强连接稳定性，同时，在电子设备处于展开状态的情况下，可以确保底座400能够更加稳定地支撑柔性显示屏。可选地，在该实施例中，连接件500的数量可以为多个，一部分连接件500可以设在远离轴瓦210的位置以连接底座400和摆臂压盖300，另一部分连接件500可以设在靠近轴瓦210的位置以连接底座400和摆臂压盖300，即从第一避让口211处连接底座400和摆臂压盖300。
可选地，第一延伸部331的自由端和第二延伸部332的自由端相对设置，压盖本体320设有第一弧形面321，第一延伸部331和第二延伸部332中一者设有第二弧形面，另一者设有平面，第一弧形面321沿转动轴线所在方向 的两端分别与第二弧形面和平面相对，以形成滑槽310。在此种情况下，轴瓦210可以在第一弧形面321和第二弧形面形成的滑槽310中平稳地滑动，该滑槽310对轴瓦的运动约束性能较好，而第一弧形面321和平面形成的滑槽310对轴瓦210的运动约束性能较差，因此，在整体上对轴瓦210的运动稳定性有不良影响。
为避免上述不良影响，在另一种实施例中，第一延伸部331和第二延伸部332上均设有弧形面，即第一延伸部331设有第二弧形面，第二延伸部332设有第三弧形面，第一弧形面321沿转动轴线所在方向的两端分别与第二弧形面和第三弧形面相对，以形成滑槽310。在此种情况下，滑槽310的两端均与轴瓦210形成较大的接触面积，滑槽310对轴瓦210的两端均具有较好的运动约束性能，这使得轴瓦210能够更稳定地沿着滑槽310转动，进而电子设备的折叠过程和展开过程会更加平顺，同时可以减小滑槽310和轴瓦210的磨损。
该实施例中，在成型滑槽310和压盖本体320时，需使成型滑槽310的模具滑块和成型压盖本体320的模具分体设置，并且在成型结束取出模具和模具滑块时，需先取出成型压盖本体320的模具，然后再取出成型滑槽310的模具滑块，具体是将成型滑槽310的模具滑块沿轴瓦210的转动方向取出，即沿滑槽310的周向滑动取出，即将第一延伸部331和第一弧形面321之间的模具滑块滑动取出，以及将第二延伸部332和第一弧形面321之间的模具滑块滑动取出。
可选地，由于轴瓦210的形状为等直径圆弧形状，因此，可以将第二弧形面和第三弧形面均设置为等直径圆弧面，以及将第一弧形面321的仅与第一延伸部331和第二延伸部332相对设置的部分设置为等直径圆弧面，通过此种设置方式形成的滑槽310与轴瓦210的滑动配合的适配度更高，第一弧形面321的其他部分可以设置为不等直径的圆弧面，这就意味着成型第一弧形面321的模具的结构较为复杂，进而制造成本较高。
为方便制造及简化成型第一弧形面321的模具，在另一种实施例中，第一弧形面321的其他部分也设置为等直径的圆弧面，即第一弧形面321的整体均为等直径圆弧面，由此可使得成型第一弧形面321的模具的结构较为简单，且方便制造，同时制造的成本较低。
一种实施例中，电子设备的柔性显示屏设于第一机身110和第二机身120，在电子设备处于展开状态的情况下，可以通过底座400来支撑柔性显示屏。
在另一种实施例中，为降低底座400的重量，底座400开设有第二避让口410，为避免在电子设备处于展开状态时，柔性显示屏在第二避让口410处发生塌陷的情况，转轴机构还包括第一支撑部600，第一支撑部600设于轴瓦210，在电子设备处于展开状态时，第一支撑部600穿过第二避让口410，并与柔性显示屏接触，以支撑柔性显示屏，即避免电子设备处于展开状态时，柔性显示屏与第二避让口410相对的部分发生下沉现象。
可选地，为降低转轴机构的重量，可以在第一支撑部600上开设有第一减重槽212，但这会影响第一支撑部600对柔性显示屏的支撑效果。
因此，在另一种实施例中，轴瓦210背离第一支撑部600的一侧开设有第一减重槽212；和/或，摆臂压盖300包括压盖本体320，压盖本体320背离滑槽310的一侧开设有第二减重槽322，第一减重槽212和第二减重槽322均用于减轻转轴机构的重量，进而减轻电子设备的重量。
可选地，转轴机构还包括中框支架，中框支架与第一机身110或第二机身120相连，摆臂200的第一端与中框支架通过插销相连，以此实现摆臂200与第一机身110或第二机身120相连，为避免第一机身110和第二机身120朝转轴机构发生轻微运动，摆臂200包括摆臂本体220和沿摆臂200的转动轴线所在方向凸出摆臂本体220的第二支撑部230，第二支撑部230与第一机身110或第二机身120始终抵接，以避免电子设备处于折叠或展开状态时，第一机身110和第二机身120朝转轴机构发生轻微运动，进而避免影响柔性显示屏的显示效果。
可选地，本申请还公开一种电子设备，所公开的电子设备包括前文所述的转轴机构、第一机身110和第二机身120，第一机身110和第二机身120通过转轴机构转动连接。可选地，摆臂200的数量为至少两个，其中一部分摆臂200与第一机身110相连，另一部分摆臂200与第二机身120相连，从而实现第一机身110和第二机身120的同步转动。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
