本申请要求于2022年09月20日提交中国专利局、申请号为202211146001.8、申请名称为“转动机构及电子设备”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
本申请涉及电子产品技术领域，尤其涉及一种转动机构及电子设备。
背景技术
随着柔性折叠屏技术日趋成熟，折叠终端产品的应用也越来越广泛。折叠终端产品(如折叠手机、折叠平板、折叠电脑等)需要满足较高的外观形态及较好的体验，这样才能被消费者所接受。目前，折叠终端产品常通过装设于轴盖支架上的摆臂实现转动运动。然而，现有的摆臂滑槽的结构设置易影响整机厚度。
发明内容
本申请的实施例提供一种转动机构及电子设备，转动机构的结构设置有利于在保证摆臂的转动运动的基础上，实现整机的减薄。
第一方面，本申请提供一种转动机构，所述转动机构包括支架、第一主摆臂和第二主摆臂；
所述支架设有第一转动槽和第二转动槽，所述第一转动槽和所述第二转动槽分布在所述支架的相对两侧；
所述第一转动槽包括第一滑轨和两个第二滑轨，两个所述第二滑轨分别位于所述第一滑轨的相对两侧，并与所述第一滑轨沿所述支架的长度方向并排设置，所述第一主摆臂安装于所述第一转动槽，所述第一主摆臂能够在所述第一滑轨和两个所述第二滑轨上滑动，所述第一主摆臂能够相对所述支架转动；
所述第二转动槽包括第三滑轨和两个第四滑轨，两个所述第四滑轨分别位于所述第三滑轨的相对两侧，并与所述第三滑轨沿所述支架的长度方向并排设置，所述第二主摆臂安装于所述第二转动槽，所述第二主摆臂能够在所述第三滑轨和两个所述第四滑轨上滑动，所述第二主摆臂能够相对所述支架转动，所述第二主摆臂与所述第一主摆臂的转动方向相反。
可以理解的是，第一滑轨和第二滑轨能够供摆臂在其上滑动，而通过摆臂在第一滑轨和第二滑轨上的滑动运动，可以实现摆臂与支架的转动运动。此设置下，通过将第一转动槽(摆臂滑槽)设置在支架上，可以充分利用支架上的空间而合理布局第一转动槽的结构，相较于现有技术中将摆臂滑槽设置在摆臂上的结构，可以使摆臂在折叠状态下占用较小的空间，有利于实现整机的轻薄化。
另外，通过在第一转动槽设置第一滑轨和两个第二滑轨，能够使摆臂的滑动轨迹由第一滑轨和两个第二滑轨共同限定。一方面，由第一滑轨和两个第二滑轨共同限定摆臂的滑动轨迹可以降低对第一转动槽的精度要求，从而降低支架的加工难度和加工成本。另一方面，由第一滑轨和两个第二滑轨共同限定摆臂的滑动轨迹可以使第一滑轨和两个第二滑轨呈分布式排列，分布式排列的多个滑轨能够增加第一转动槽的强度，使摆臂在滑轨上滑动 时不易变形卡死，可靠性佳。
第二转动槽的效果同理。
一种可能的实施方式中，所述第一主摆臂包括第一滑动部和两个第二滑动部，两个所述第二滑动部连接于所述第一滑动部的相对两侧，所述第一滑动部安装于所述第一滑轨，每一所述第二滑动部均安装于一个所述第二滑轨。
此设置下，能够使第一转动体的结构与支架的第一转动槽的结构相匹配，第一滑动部的结构与第一滑轨的结构相匹配，第二滑动部的结构与第二滑轨的结构相匹配，有利于使第一主摆臂能够相对支架进行流畅的转动运动。
一种可能的实施方式中，所述第一滑动部和两个所述第二滑动部配合形成第一凹陷区，部分所述第一滑轨位于所述第一凹陷区。
此设置下，能够使第一滑动部相对于两个第二滑动部内凹。当第一滑动部在第一滑轨上滑动时，第一滑动部相对于两个第二滑动部内凹而形成的第一凹陷区能够提供一定的空间以收容第一滑轨，有利于在局限化的空间布局里提高转动机构的空间利用率，可靠性佳。
一种可能的实施方式中，所述第一主摆臂上设有第一通孔，所述第一通孔与所述第一凹陷区连通，所述第一通孔用于供所述第一滑轨穿过。
此设置下，能够使第一滑轨和第一主摆臂的转动运动不会相互影响，有效避免因第一滑轨阻碍第一主摆臂转动而导致的转动机构卡死的问题发生。
一种可能的实施方式中，所述第一滑轨包括两个相对设置的第一凸部，每一所述第一凸部背离所述第一转动槽的底壁的表面均与所述第一滑动部接触，每一所述第一凸部均包括第一端和第二端，所述第一端相对所述第二端靠近所述支架的边缘设置，每一所述第一凸部沿垂直于所述第一转动槽的底壁方向的截面高度自所述第一端向所述第二端方向逐渐变小。
此设置下，能够使第一端作为第一凸部中的高点位置，第二端作为第一凸部中的低点位置，从而使第一滑轨的轨道路径呈现自高向低，自支架的边缘逐渐向支架的中心靠近的结构设置，有利于充分利用支架的结构空间而实现第一滑轨具有高低落差和一定倾斜角度的轨道设置，可靠性佳。
一种可能的实施方式中，所述转动机构还包括基座，所述支架固定至所述基座，所述基座上设有安装柱，所述第一滑轨还包括第一连接部，所述第一连接部连接在两个所述第一凸部的第一端之间，所述第一连接部和两个所述第一凸部配合围设出安装空间，所述支架设有安装孔，所述安装孔位于两个所述第一凸部之间并靠近所述第一连接部设置，所述安装柱穿过所述安装孔，所述安装柱位于所述安装空间内。
此设置下，一方面，能够通过安装孔和安装柱的对应设置而实现支架与基座装配时的快速定位，有利于方便快捷的将支架组装至基座上。另一方面，能够通过安装孔与安装柱的对应设置而实现支架与基座的卡持连接，限制支架与基座之间的相对移动，保证支架与基座之间不发生倾斜、错位、晃动等移位情况。另外，第一连接部和两个凸部配合形成的安装空间还可以收容安装柱，能够在不额外占用转动机构的空间的基础上，充分利用支架上的空间，有效提高支架的空间利用率。
一种可能的实施方式中，每一所述第一滑轨均包括第一凸块和第一轨道结构，所述第 一凸块连接于所述第一转动槽的侧壁，所述第一轨道结构连接于所述第一转动槽的底壁，所述第一凸块与所述第一轨道结构间隔设置，所述第二滑动部位于所述第一凸块与所述第一轨道结构的间隙区域内。
通过在第一转动槽的侧壁设置第一凸块，可以对安装于第一转动槽的摆臂起到限位作用，有利于避免安装于第一转动槽的摆臂脱离第一转动槽的情况发生。示例性地，第一轨道结构可以为弧形。
一种可能的实施方式中，所述第一轨道结构设有第一镂空部，所述第一镂空部与所述第一凸块相对设置，所述第一镂空部贯穿所述第一转动槽的底壁。
可以理解的是，通过设置第一镂空部，可以使支架可以通过模具成型的方式制备，简化了支架的加工工艺，有利于降低生产成本，提高生产效率。
一种可能的实施方式中，所述第一转动槽和所述第二转动槽为一体式结构。
可以理解的是，第一转动槽和第二转动槽均为一体式结构。相对于现有技术中转动槽通过多个零件拼接而成的组装结构，一体式结构的第一转动槽和第二转动槽具有不需要拆件、零件数量少、加工和制造都较为简便、成本较低、尺寸精度高等优点。能够将因多个零件拼接而成所造成的组装公差较大、存在虚位搓动、焊接难度高、返修难度大等问题所造成的不良影响降低到最小，可靠性佳。
一种可能的实施方式中，所述转动机构还包括基座，所述支架固定至所述基座，所述第一转动槽和所述第二转动槽在所述基座上的正投影完全落在所述基座上。
可以理解的是，由于第一转动槽和第二转动槽的正投影完全落在基座上，故而可以使支架适配第一转动槽和第二转动槽的结构设置而也处于基座所划分出的空间范围内，使支架的尺寸适配基座的尺寸而不会相对基座凸出，也即为，第一转动槽和第二转动槽不会相对基座凸出。此设置下，能够将因支架相对基座凸出而对整机厚度的影响降低到最小，有利于实现整机的轻薄化。
第二方面，本申请还提供一种电子设备，所述电子设备包括第一壳体、第二壳体和如上所述的转动机构，所述转动机构连接在所述第一壳体和所述第二壳体之间。

本申请的实施例提供一种转动机构及应用转动机构的电子设备，转动机构的结构设置有利于在保证摆臂的转动运动的基础上，实现整机的减薄。
其中，电子设备可以为任何具有可折叠的性能的设备，其能够在用户的操作下实现展开和闭合。电子设备包括但不限于手机(cellphone)、笔记本电脑(notebook computer)、平板电脑(tablet personal computer)、膝上型电脑(laptop computer)、个人数字助理(personal digital assistant)、可穿戴式设备(wearable device)或车载设备(mobile device)等。本申请实施例中，以电子设备为手机为例进行说明。
图1是本申请实施例提供的电子设备400处于折叠状态的结构示意简图，图2是图1所示电子设备400处于中间状态时的结构示意简图，图3是图1所示电子设备400处于展开状态时的结构示意简图。其中，图2所示电子设备400的展开角度α为120度，图3所示电子设备400的展开角度β为180度。
为了便于描述，将电子设备400的长度方向定义为X方向，将电子设备400的宽度方向定义为Y方向，将电子设备400的厚度方向定义为Z方向。X方向、Y方向和Z方向两两相互垂直。
需要说明的是，本申请实施例举例说明的角度均允许存在少许偏差。例如，图2所示电子设备400的展开角度α为120度是指，α可以为120度，也可以大约为120度，比如110度、115度、125度或130度等。图3所示电子设备400的展开角度β为180度是指，β可以为180度，也可以大约为180度，比如0度、5度、185度和190度等。后文中举例说明的角度可做相同理解。
本申请实施例所示电子设备400为可发生一次折叠的电子设备。在其他一些实施例中，电子设备400也可以为可发生多次(两次以上)折叠的电子设备。此时，电子设备400可以包括多个部分，相邻两个部分可相对靠近折叠至电子设备400处于折叠状态，相邻两个部分可相对远离展开至电子设备400处于展开状态。
图4是本申请实施例提供的电子设备400的一种结构示意图，图5是图4所示电子设备400的爆炸示意图。
请结合参阅图4和图5，电子设备400包括折叠装置200和柔性显示屏300，柔性显示屏300安装于折叠装置200。柔性显示屏300包括第一部分310、第二部分320和可折叠部 分330。可折叠部分330位于第一部分310和第二部分320之间，可折叠部分330可以发生弯折。第一部分310、第二部分320和可折叠部分330共同构成柔性显示屏300。
本申请的实施例中，柔性显示屏300可以为有机发光二极管(organic light-emitting diode，OLED)显示屏，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light-emitting diode，AMOLED)显示屏，迷你发光二极管(mini organic lightemitting diode)显示屏，微型发光二极管(micro organic light-emitting diode)显示屏，微型有机发光二极管(micro organic light-emitting diode)显示屏，量子点发光二极管(quantum dot light emitting diodes，QLED)显示屏。
折叠装置200包括第一壳体210、第二壳体220和转动机构100，第一壳体210设有第一容置槽230，第二壳体220设有第二容置槽240，第一容置槽230和第二容置槽240连通形成容置槽。转动机构100安装于容置槽，并与第一壳体210和第二壳体220固定连接，以实现第一壳体210和第二壳体220之间的转动连接。第一壳体210和第二壳体220可通过转动机构100相对转动，使得折叠装置200在折叠状态和展开状态之间相互切换。第一壳体210和第二壳体220还设有容置空间(图未示)，容置空间用于容纳电子设备400的处理器、电路板、摄像模组等电子元件以及结构元件。
其中，如图1所示，第一壳体210和第二壳体220的相对转动使得折叠装置200处于折叠状态，是指第一壳体210和第二壳体220通过转动机构100转动，且彼此相互靠近，第一壳体210与第二壳体220承载柔性显示屏300的面相对。实际上，在应用过程中，折叠装置200完全折叠状态下，装于第一壳体210和第二壳体220的柔性显示屏300折叠后，第一部分310和第二部分320层叠并部分接触，当然，也可以完全接触。
如图2所示，第一壳体210和第二壳体220相对转动使得折叠装置200处于中间状态，是指第一壳体210和第二壳体220通过转动机构100转动，且彼此相互远离使第一壳体210和第二壳体220之间的夹角越来越大，或者，是指第一壳体210和第二壳体220通过转动机构100转动，且彼此相互靠近使第一壳体210和第二壳体220之间的夹角越来越小。
如图3所示，第一壳体210和第二壳体220相对转动使得折叠装置200处于展开状态，是指第一壳体210和第二壳体220通过转动机构100转动，且彼此相互远离，第一壳体210和第二壳体220之间的夹角继续增大，可以接近180度或者等于180度。
柔性显示屏300连接于折叠装置200。具体而言，第一壳体210承载柔性显示屏300的第一部分310，第二壳体220承载柔性显示屏300的第二部分320，柔性显示屏300的可折叠部分330与转动机构100相对设置。可以理解的是，第一壳体210和第二壳体220通过转动机构100相对转动，通过第一壳体210和第二壳体220相对靠近带动柔性显示屏300折叠，以使电子设备400折叠。当电子设备400处于折叠状态时，柔性显示屏300的可折叠部分330发生弯折，第一部分310和第二部分320相对设置。此时，柔性显示屏300处于第一壳体210和第二壳体220之间，可大大降低柔性显示屏300被损坏的概率，实现对柔性显示屏300的有效保护。
本申请的实施例中，第一壳体210和第二壳体220通过转动机构100相对转动，通过第一壳体210和第二壳体220相对远离带动柔性显示屏300展开，以使电子设备400展开至中间状态。当电子设备400处于中间状态时，第一壳体210和第二壳体220展开至夹角 为α，第一部分310和第二部分320相对展开，并带动可折叠部分330展开。此时，第一部分310和第二部分320之间的夹角为α。本实施例中，α为120度。在其它实施例中，α也可以大约为120度，也可以是110度、115度、125度或130度等。
第一壳体210和第二壳体220通过转动机构100相对转动，通过第一壳体210和第二壳体220相对远离带动柔性显示屏300进一步展开，直至电子设备400展开。当折叠装置200处于展开状态时，第一壳体210和第二壳体220之间的夹角为β。可折叠部分330展开，第一部分310和第二部分320相对展开。此时，第一部分310、第二部分320和可折叠部分330之间的夹角均为β，柔性显示屏300具有大面积的显示区域，实现电子设备400的大屏显示，提高用户的使用体验。本实施例中，β为180度。在其它实施例中，β也可以大约为180度，可以是0度、5度、185度和190度等。
请结合参阅图6和图7，图6是图5所示的电子设备的转动机构100的结构示意图，图7是图6所示的转动机构100的分解示意图。
转动机构100可以包括基座10、支架20、转动摆臂组件30和压板摆臂组件40。支架20安装于基座10，支架20与基座10固定连接。转动摆臂组件30安装于支架20，并可相对支架20转动，通过转动摆臂组件30与支架20的转动连接能够实现基座10与转动摆臂组件30的转动连接。压板摆臂组件40安装于支架20，并可相对支架20转动，通过压板摆臂组件40与支架20的转动连接能够实现基座10与压板摆臂组件40的转动连接。示例性地，压板摆臂组件40可以与转动摆臂组件30滑动且转动连接。转动摆臂组件30相对基座10转动时，带动压板摆臂组件40相对基座10转动，进而实现转动机构100的转动，并使转动机构100在折叠状态和展开状态之间相互切换。
为了便于描述，本申请的实施例设置对称轴O(如图6所示)。其中，对称轴O与X方向垂直，且对称轴O穿过转动机构100的中心。
需说明的是，图6和图7的目的仅在于示意性的描述基座10、支架20和转动摆臂组件30的连接关系，并非是对各个设备的连接位置、具体构造及数量做具体限定。而本申请实施例示意的结构并不构成对转动机构100的具体限定。在本申请另一些实施例中，转动机构100可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
请结合参阅图8和图9，图8是图6所示的转动机构100的基座10和支架20的结构示意图，图9是图8所示的支架20与基座10的组装示意图。基座10可以包括底板11、第一端板12和第二端板13。第一端板12和第二端板13分别连接至底板11的两侧，第一端板12和第二端板13在Y方向相对设置。底板11设有多个安装柱14，多个安装柱14在底板11上间隔设置。在X方向上，位于底板11一侧的多个安装柱14与位于底板11另一侧的多个安装柱14关于对称轴O对称设置。
支架20固定连接至基座10，支架20与基座10的底板11相对设置。示例性地，支架20与基座10可以通过螺栓、胶水、焊接等方式固定连接。本申请的实施例中，支架20由四个子支架组成，本实施例中，四个子支架为分体式结构。四个子支架分别为第一子支架201、第二子支架202、第三子支架203和第四子支架204。第一子支架201、第二子支架202、第三子支架203和第四子支架204在Y方向上依次间隔排布。其中，第一子支架201 位于基座10的Y轴负方向一侧，第四子支架204位于Y轴正方向一侧。当然，在其他的一些实施例中，四个子支架也可以是一体成型结构。
请参阅图10，图10是图6所示的支架20的第一子支架201的结构示意图。
第一子支架201固定连接至基座10，第一子支架201设有第一转动槽21a和第二转动槽22a，第一转动槽21a和第二转动槽22a在X方向和Y方向上均间隔设置。第一转动槽21a和第二转动槽22a在基座10上的正投影可以完全落在基座10上。可以理解的是，由于第一转动槽21a和第二转动槽22a的正投影完全落在基座10上，故而可以使第一子支架201适配第一转动槽21a和第二转动槽22a的结构设置而也处于基座10所划分出的空间范围内，使第一子支架201的尺寸适配基座10的尺寸而不会相对基座10凸出，也即为，第一转动槽21a和第二转动槽22a不会相对基座10凸出。此设置下，能够将因第一子支架201相对基座10凸出而对整机厚度的影响降低到最小，有利于实现整机的轻薄化。
本申请的实施例中，第一转动槽21a和第二转动槽22a均为一体式结构。相对于现有技术中转动槽通过多个零件拼接而成的组装结构，一体式结构的第一转动槽21a和第二转动槽22a具有不需要拆件、零件数量少、加工和制造都较为简便、成本较低、尺寸精度高等优点。能够将因多个零件拼接而成所造成的组装公差较大、存在虚位搓动、焊接难度高、返修难度大等问题所造成的不良影响降低到最小，可靠性佳。
请继续参阅图10，第一转动槽21a可以包括第一滑轨211a和两个第二滑轨212a。第一滑轨211a设于第一转动槽21a的底壁。两个第二滑轨212a分别设于第一转动槽21a的两个相对设置的侧壁，两个第二滑轨212a分别位于第一滑轨211a的相对两侧，两个第二滑轨212a与第一滑轨211a沿支架20的长度方向(Y方向)并排设置。示例性地，第一转动槽21a的底壁为弧形。
可以理解的是，第一滑轨211a和第二滑轨212a能够供摆臂在其上滑动，而通过摆臂在第一滑轨211a和第二滑轨212a上的滑动运动，可以实现摆臂与第一子支架201的转动运动。此设置下，通过将第一转动槽21a(摆臂滑槽)设置在第一子支架201上，可以充分利用第一子支架201上的空间而合理布局第一转动槽21a的结构，相较于现有技术中将摆臂滑槽设置在摆臂上的结构，可以使摆臂在折叠状态下占用较小的空间，有利于实现整机的轻薄化。
另外，通过在第一转动槽21a设置第一滑轨211a和两个第二滑轨212a，能够使摆臂的滑动轨迹由第一滑轨211a和两个第二滑轨212a共同限定。一方面，由第一滑轨211a和两个第二滑轨212a共同限定摆臂的滑动轨迹可以降低对第一转动槽21a的精度要求，从而降低第一子支架201的加工难度和加工成本。另一方面，由第一滑轨211a和两个第二滑轨212a共同限定摆臂的滑动轨迹可以使第一滑轨211a和两个第二滑轨212a呈分布式排列，分布式排列的多个滑轨能够增加第一转动槽21a的强度，使摆臂在滑轨上滑动时不易变形卡死，可靠性佳。

本申请的实施例中，第一轨道结构218a设有第一镂空部219a，第一镂空部219a与第一凸块217a相对设置，第一镂空部219a沿Z方向贯穿第一转动槽21a的底壁。可以理解的是，通过设置第一镂空部219a，可以使第一子支架201可以通过模具成型的方式制备，简化了第一子支架201的加工工艺，有利于降低生产成本，提高生产效率。
第二转动槽22a可以包括第三滑轨221a和两个第四滑轨222a。第三滑轨221a设于第二转动槽22a的底壁。两个第四滑轨222a分别设于第二转动槽22a的两个相对设置的侧壁，两个第四滑轨222a分别位于第三滑轨221a的相对两侧，两个第四滑轨222a与第三滑轨221a 沿支架20的长度方向(Y方向)并排设置。示例性地，第二转动槽22a的底壁为弧形，

另外，通过在第二转动槽22a设置第三滑轨221a和两个第四滑轨222a，能够使摆臂的滑动轨迹由第三滑轨221a和两个第四滑轨222a共同限定。一方面，由第三滑轨221a和两个第四滑轨222a共同限定摆臂的滑动轨迹可以降低对第二转动槽22a的精度要求，从而降低第一子支架201的加工难度和加工成本。另一方面，由第三滑轨221a和两个第四滑轨222a共同限定摆臂的滑动轨迹可以使第三滑轨221a和两个第四滑轨222a呈分布式排列，分布式排列的多个滑轨能够增加第二转动槽22a的强度，使摆臂在滑轨上滑动时不易变形卡死，可靠性佳。
