Description

一种转动机构及可折叠的电子设备
本申请要求于2022年11月15日提交到国家知识产权局、申请号为202223033825.2、名称为“一种转动机构及可折叠的电子设备”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
本申请涉及折叠屏终端技术领域，特别涉及一种转动机构及可折叠的电子设备。
背景技术
可折叠的电子设备，例如：折叠屏手机，可以在机身上贴合内折方式或外折方式的柔性可折叠显示屏，以在机身完全展开后为用户提供更大的显示区域。机身主要包括两个框体，两个框体可绕转动机构转动。其中，转动机构包括轴盖及设置在轴盖上的滑槽支架和主摆臂，滑槽支架所形成的滑槽与对应的主摆臂一端两侧的滑动部滑动连接，主摆臂的另一端与对应侧的框体连接。两侧的框体所连接的主摆臂可在对应滑槽内往复滑动，以实现机身的开合。
为了防止主摆臂在闭合过程中从滑槽内脱出，相关技术是在主摆臂的滑动部上设置凸出部，其中，该凸出部能够在主摆臂闭合时沿滑槽支架内的限位槽滑动至滑槽支架上设置的止位部上，以对主摆臂的滑动进行限位。为了方便组装，滑槽支架通常为拆件式结构，主要包括上支架和下支架，上支架和下支架被配置为可形成与滑动部相适配的滑槽。在转动机构的组装过程中，可以先将下支架安装在轴盖上，再将主摆臂安装在下支架上，具体将滑动部嵌入至滑槽内，将凸出部伸入至限位槽内，最后将上支架对应焊接在下支架的预设位置，以形成与主摆臂相适配的滑槽。
然而，由于滑槽支架为拆件式结构，零件数量较多，因此整体的配合公差链比较长，而且由于焊接的过程中会存在公差，因此在将上支架对应焊接在下支架的预设位置以后，上支架相对于下支架的位置可能会存在一定的偏移，造成滑槽的宽度增大，进而使得主摆臂的滑动部与滑槽的配合间隙增大，主摆臂在滑动的过程中容易产生晃动，影响用户体验。
发明内容
本申请实施例提供一种转动机构及可折叠的电子设备，减小甚至避免了转动机构在装配过程中的公差，从而改善或者避免了滑槽支架上的滑槽的宽度偏大，而与主摆臂上的滑动部配合间隙过大的情况发生，提高了主摆臂在滑动过程中的稳定性。
本申请实施例提供一种转动机构，包括主摆臂、滑槽支架和轴盖，该主摆臂包括滑动部和凸出部，主摆臂包括沿长度方向相对设置的第一端和第二端，第二端用于连接电子设备的框体，凸出部设置在主摆臂沿长度方向相对的两端中的第一端端面上，滑动部设置在主摆臂沿宽度方向相对的侧面，该滑槽支架具有与滑动部相适配的滑槽，以及用于容纳凸出部的滑道，滑道为弧形槽，在滑动部在滑槽内往复滑动时，凸出部沿滑道滑 动，滑槽支架为一体式结构，该轴盖位于滑槽支架背向主摆臂的一侧，轴盖和滑槽支架的其中一者上设置有止位部，止位部凸出于轴盖朝向滑槽支架的内表面，且位于滑道靠近滑槽支架边缘的一端，在主摆臂从展开位置转动到闭合位置时，凸出部与止位部配合，以防止主摆臂从滑槽靠近滑槽支架边缘的一端脱出。
本申请实施例提供的转动机构，凸出部设置在主摆臂沿长度方式相对的两端中的第一端端面上，止位部设置在轴盖和滑槽支架的其中一个上，滑槽支架为一体式结构，且开设有与凸出部相适配的滑道，一方面，保证了设有凸出部的主摆臂能够装入至一体式结构的滑槽支架内，使得凸出部在主摆臂闭合后与止位部配合，而确保主摆臂不会脱出滑槽支架与轴盖的组装结构中，另一方面，整体零件数量少，方便组装，而且也可以避免滑槽支架上形成的滑槽由于装配问题造成的宽度增大的情况，从而使得滑槽与主摆臂配合间隙适中，主摆臂在滑动的过程不易晃动，提高用户体验。
在一种可行的实现方式中，止位部朝向滑道的一侧具有第一端面，在主摆臂从展开位置转动到闭合位置时，凸出部抵接在第一端面上。这样，凸出部与止位部不易在抵接的位置产生滑动或偏移，抵接更加稳定和牢靠。
在一种可行的实现方式中，滑道包括滑道内底壁、沿凸出部的滑动方向相对设置的开口端和滑道端壁，滑道内底壁位于开口端与滑道端壁之间，凸出部用于在滑动部沿滑槽往复滑动时沿滑道内底壁活动，滑道端壁被配置为止位部的第一端面，在主摆臂从展开位置往闭合位置转动时，凸出部经开口端进入至滑道内，且在主摆臂转动至闭合位置时，凸出部抵接在滑道端壁上。这样，滑道可以较好地适配凸出部的运动轨迹，且在滑道端壁对凸出部进行止位，结构上简单有效，易于加工。
在一种可行的实现方式中，凸出部一体成型设置在主摆臂的第一端端面上。这样，凸出部与主摆臂一体成型，加工较为简单，并且不易脱落，结构的可靠性更高。
在一种可行的实现方式中，主摆臂的第一端端面向第二端的方向形成有凹陷部，凹陷部靠近第二端的一端还设置有容纳槽，容纳槽与凹陷部连通，凸出部嵌设于容纳槽内，且凸出部的一端伸出凹陷部的表面。这样，凸出部可拆卸地连接在主摆臂上，使得主摆臂、滑槽支架和轴盖之间的组装方式可以更加灵活，也能够更好地适应一体式结构的滑槽支架。
在一种可行的实现方式中，止位部设置在轴盖上。这样，在轴盖与滑槽支架组装之后，止位部才会与主摆臂的凸出部配合并起到防脱的作用，主摆臂与滑槽支架可以先完成组装，再整体组装在轴盖上，整体结构构思巧妙，易于加工，且成本较低，方便带有凸出部的主摆臂的组装。
在一种可行的实现方式中，止位部还包括与第一端面连接的第二端面，在主摆臂转动至展开位置时，主摆臂朝向轴盖的第一侧面抵接于第二端面。这样，在主摆臂从闭合位置转动至展开位置后，止位部的第二端面还可以起到对主摆臂的限位作用，从而防止主摆臂转动过度，对其他零部件造成损伤。
在一种可行的实现方式中，止位部的第二端面垂直于止位部的第一端面。这样，使得主摆臂闭合位置和展开位置之间可以转动90度，更加符合用户的实际使用需求和体验。
在一种可行的实现方式中，滑道设置在滑槽支架朝向主摆臂的一侧表面。这样，滑道并未凸出滑槽支架的表面，从而不会对主摆臂的运动轨迹造成影响，也能使得凸出部 在主摆臂上的设置可以更加灵活。
在一种可行的实现方式中，滑槽支架朝向主摆臂的一侧表面形成有凸台，凸台向内凹陷形成滑道，滑道将凸台分隔为第一凸起和两个第二凸起，两个第二凸起相对设置在第一凸起的两侧，第一凸起和两个第二凸起共同围合成滑道，其中，第一凸起被配置为止位部，第一凸起朝向滑道的一侧为滑道端壁，主摆臂上的凹陷部用于在凸出部往滑道内滑动时避让第二凸起，主摆臂上还形成有避让孔，第一凸起用于在主摆臂处于展开位置时穿设于避让孔。这样，止位部设置在滑槽支架上，有利于轴盖的标准加工，另外第二凸起的弧面可以设置的较长且与主摆臂的凹陷部底面的转动轨迹相适配，从而增加主摆臂转动时与滑槽支架的滑动配合面积，使得主摆臂的转动可以更加顺畅，用户体验更佳。
在一种可行的实现方式中，在主摆臂转动至展开位置时，主摆臂朝向轴盖的第一侧面抵接于滑槽支架边缘背向轴盖的顶面。这样，即使设置了第一凸起，也不会限制主摆臂的展开位置。
在一种可行的实现方式中，凸出部设置在主摆臂的第一端的中心位置，主摆臂包括两个滑动部，两个滑动部分别设置在第一端沿宽度方向相对的两侧。这样，主摆臂的结构可以更加对称，从而在转动时受力较为均匀，有利于提升用户的使用手感。
另一方面，本申请实施例提供一种可折叠的电子设备，包括如第一方面以及第一方面的各种可实现方式中任一项的转动机构，以及可绕该转动机构转动的第一框体和第二框体，其中，第一框体和第二框体分别连接在转动机构中主摆臂的第二端。
本申请实施例提供的电子设备，采用的转动机构的滑槽支架为一体式结构，凸出部设置在主摆臂沿长度方式相对的两端中的第一端端面上，止位部设置在轴盖和滑槽支架的其中一个上，整体零件数量少，方便组装，而且也可以避免滑槽支架上形成的滑槽由于装配问题造成的宽度增大的情况，从而使得滑槽与主摆臂配合间隙适中，主摆臂在滑动的过程不易晃动，提高用户体验。

图1a是一种内折叠屏手机的形态示意图，图1b是一种外折叠屏手机的形态示意图。参照图1a和图1b所示，本申请实施例提供一种可折叠的电子设备。
需要说明的是，本申请实施例的电子设备可以包括但不限于手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、手持计算机、触控电视、对讲机、上网本、POS机、个人数字助理(personal digital assistant，PDA)、可穿戴设备例如耳机、蓝牙眼镜等、虚拟现实设备等具有可折叠功能的移动或固定终端，此处不做限制。
下面以折叠屏手机为例，进行具体说明。
参照图1a和图1b所示，其中，可以将折叠屏手机的宽度方向定义为x方向，将手机的高度方向定义为y方向，将手机的厚度方向定义为z方向。图1示出的为沿x方向尺寸小于沿y方向尺寸的形态的手机。对于沿x方向尺寸大于沿y方向尺寸的形态的手机图1中不再单独示意。参照图1a和图1b所示，传统的折叠屏手机根据其屏幕弯折方向的不同可以包括内折叠屏手机和外折叠屏手机等。其中，内折叠屏手机如图1a所示，外折叠屏手机如图1b所示。
参照图1a所示，内折叠屏手机的机身2能够向可折叠显示屏3一侧折叠，可折叠显示屏3在机身2折叠后隐藏于机身2内侧，由此形成可折叠显示屏3在机身2折叠状态下隐藏，在机身2展开状态下呈现正常直屏的效果。外折叠屏手机的机身2能够向可折叠显示屏3的背面一侧折叠，可折叠显示屏3在机身2折叠后环绕于机身2外侧，由此形成可折叠显示屏3在机身2折叠状态下环绕机身2，形成环绕屏，在机身2展开状态下呈现正常直屏的效果。
图2是内折叠屏手机展开状态的结构示意图。参照图2所示，图2为内折叠屏手机展开状态下xz平面的示意图，该内折叠屏手机可以包括：机身2和可折叠显示屏3，可折叠显示屏3贴设于机身2的一个表面。其中，对于可以实现一次对折的内折叠屏手机来说，其机身2可以包括第一框体50和第二框体60，第一框体50和第二框体60分别设置于转动机构1的两侧。当用户对机身2施加一定的力以转动第一框体50和第二框体60时，第一框体50和第二框体60可绕转动机构1转动，实现展开和折叠。在机身2其中一个框体(例如：第二框体60)的另一个表面上还贴设有外屏4，以便于在可折叠显示屏3在机身2折叠状态下隐藏后，内折叠屏手机仍能通过外屏4实现正常直屏效果。
图3是转动机构的完整结构示意图。如图3所示，转动机构1可以包括轴盖30，以及设置在轴盖30上的滑槽支架20和主摆臂10。另外转动机构1还包括副摆臂70，副摆臂70用于控制电子设备的可折叠显示屏的闭合形态。图3中副摆臂70以xxx进行标示，以便于与主摆臂10进行更明显地区分。转动机构1两侧还连接有可绕转动机构1转动的第一框体50和第二框体60。滑槽支架20所形成的滑槽与对应的主摆臂10一端两侧的滑动部滑动连接，主摆臂10的另一端通过连接块与对应侧的第一框体50(或者第二框体60)连接。第一框体50和第二框体60所连接的主摆臂10可在对应滑槽内往复滑动，以实现机身的开合。为了防止主摆臂10在闭合过程中从滑槽内脱出，通常需要在转动机构1上设置防脱结构。其中，需要说明的是，主摆臂10和副摆臂70均可以为多个，并按照预设规则排布，例如：沿电子设备的y方向主摆臂10和副摆臂70在转动机构1的一侧交替设置，沿平行于电子设备的x方向主摆臂10和副摆臂70相对设置等，本申请实施例对主摆臂10和副摆臂70的具体排布方式不作限定，后续只以单个主摆臂10为例进行具体说明。
图4是传统的转动机构中主摆臂位于闭合位置时的示意图。图5是传统的转动机构中主摆臂位于展开位置时的示意图。如图4和图5所示，相关技术中的转动机构100包括设置在主摆臂110的滑动部111上的凸出部112，该凸出部112能够在主摆臂110闭合时沿滑槽支架120内的限位槽L滑动至滑槽支架120上设置的止位部121上，以对主摆臂110的滑动进行限位。
参照图4和图5所示，传统的凸出部112设置在滑动部111背向滑槽支架120正面 的一侧，使得该凸出部112与滑动部111形成朝向滑槽122内壁的弯折结构，则可以理解的是，限位槽L形成于滑槽122的内壁上，且水平向内延伸。这就使得为了在此种防脱结构下方便组装，滑槽支架120通常为拆件式结构，主要包括上支架123和下支架124，上支架123和下支架124被配置为可形成与滑动部111相适配的滑槽122。
在转动机构100的组装过程中，可以先将下支架124安装在轴盖130上，再将主摆臂110安装在下支架124上，具体将滑动部111嵌入至滑槽122内，将凸出部112伸入至限位槽L内，最后将上支架123对应焊接在下支架124的预设位置，以形成与主摆臂110相适配的滑槽122。
然而，由于上述滑槽支架120为拆件式结构，零件数量较多，因此整体的配合公差链比较长，而且由于焊接的过程中会存在公差，因此在将上支架123对应焊接在下支架124的预设位置以后，上支架123相对于下支架124的位置可能会存在一定的偏移，造成滑槽122的宽度增大，进而使得主摆臂110的滑动部111与滑槽122的配合间隙增大，主摆臂110在滑动的过程中容易产生晃动，影响用户体验。
本申请实施例提供一种转动机构及可折叠的电子设备，将滑槽支架设计为一体式结构，可以减少零件数量，也可以避免装配问题造成的滑槽宽度增大的情况，另外还对应提供有与一体式滑槽支架相适配的在第一端端面上设置有凸出部的主摆臂，以确保具有凸出部的主摆臂能够方便的装入至一体结构的滑槽支架内，凸出部通过与设置在轴盖或者滑槽支架上的止位部相配合可以防止主摆臂脱出。
下面结合附图，通过各个实施例，对本申请所提供的方案进行介绍说明。
图6是本申请实施例提供的转动机构在主摆臂位于闭合位置时的结构示意图。图7是本申请实施例提供的转动机构在主摆臂位于展开位置时的结构示意图。图8是本申请实施例提供的一种主摆臂的结构示意图，其中，视图a为主摆臂10一个角度的结构图；视图b为主摆臂10另一个角度的结构图。图9是本申请实施例提供的一种滑槽支架和止位部的结构示意图。图10是图8和图9所示的结构组装后所形成的转动机构在闭合状态的剖面示意图。图11是图10所示转动机构在展开状态的剖面示意图。参照图6至图11所示，本申请实施例提供的转动机构1包括主摆臂10、滑槽支架20和轴盖30。主摆臂10包括沿长度方向相对设置的第一端a和第二端b，第二端b用于连接电子设备的框体(例如第一框体50或第二框体60)。主摆臂10包括滑动部11和凸出部12。凸出部12设置在主摆臂10沿长度方向相对的两端中的第一端端面a1上，滑动部11设置在主摆臂10沿宽度方向相对的侧面。
滑槽支架20具有与滑动部11相适配的滑槽21，以及用于容纳凸出部12的滑道22。滑道22为弧形槽。在滑动部11在滑槽21内往复滑动时，凸出部12沿滑道22滑动，滑槽支架20为一体式结构。轴盖30位于滑槽支架20背向主摆臂10的一侧，轴盖30和滑槽支架20的其中一者上设置有止位部40(参照图9至图11所示)，止位部40凸出于轴盖30朝向滑槽支架20的内表面，且位于滑道22靠近滑槽支架20边缘的一端。在主摆臂10从展开位置转动到闭合位置时，凸出部12与止位部40配合，以防止主摆臂10从滑槽21靠近滑槽支架20边缘的一端脱出。
在一种实现方式中，参照图9所示，本申请实施例提供的止位部40朝向滑道22的一侧具有第一端面41，在主摆臂10从展开位置转动到闭合位置时，凸出部12抵接在第一端面41上。这样，凸出部12与止位部40不易在抵接的位置产生滑动或偏移，抵 接更加稳定和牢靠。
参照图8所示，在一种实现方式中，主摆臂10包括两个滑动部11，两个滑动部11分别设置在第一端a沿宽度方向相对的两侧。凸出部12可以设置在主摆臂10的第一端a的中心位置。这样，主摆臂10的结构可以更加对称，从而在转动时受力较为均匀，有利于提升用户的使用手感。在其他实现方式中，主摆臂10的第一端端面a1向第二端b的方向可以形成有凹陷部，凸出部12可以设置在凹陷部的中心位置，且凸出部12的一端伸出凹陷部的表面。或者，凸出部12也可以不设置在第一端a的中心位置。本申请实施例对凸出部12在第一端端面a1上的具体设置位置不作限定。
在一种实现方式中，参照图8所示，凸出部12可以一体成型设置在主摆臂10的第一端端面a1上。这样，凸出部12与主摆臂10一体成型，加工较为简单，并且不易脱落，结构的可靠性更高。在其他实现方式中，凸出部12也可以与主摆臂10焊接或者可拆卸连接，本申请实施例不作具体限定。
参照图9所示，图9所示的滑槽支架20和止位部40可以与图8所示的主摆臂10相适配。在一种实现方式中，滑道22可以设置在滑槽支架20朝向主摆臂10的一侧表面。具体地，滑槽支架20朝向主摆臂10的一侧表面向内凹陷形成该滑道22。滑道22可以包括滑道内底壁221、沿凸出部的滑动方向相对设置的开口端222和滑道端壁223，滑道内底壁221位于开口端222与滑道端壁223之间，凸出部用于在滑动部沿滑槽21往复滑动时沿滑道内底壁221活动。其中，滑道端壁223被配置为止位部40的第一端面41。在主摆臂10从展开位置往闭合位置转动时，凸出部12经开口端222进入至滑道22内，且在主摆臂10转动至闭合位置时，凸出部12抵接在滑道端壁223上。这样，滑道22可以较好地适配凸出部12的运动轨迹，且在滑道端壁223对凸出部12进行止位，结构上简单有效，易于加工。
在一种实现方式中，参照图9所示，止位部40可以设置在轴盖30上。这样，在轴盖30与滑槽支架20组装之后，止位部40才会与主摆臂10的凸出部12配合并起到防脱的作用，主摆臂10与滑槽支架20可以先完成组装，再整体组装在轴盖30上，整体结构构思巧妙，易于加工，且成本较低，方便带有凸出部12的主摆臂10的组装。需要说明的是，在此种实现方式下，由于止位部40设置在轴盖30上，与滑槽支架20为两个独立的部件，因此滑槽支架20上的滑道22的滑道端壁223是由止位部40的第一端面41充当的，也就是说，在轴盖30未与滑槽支架20装配的情况下，滑道22的开口端222和滑道内底壁221，与滑道端壁223是分离的状态。
另外，在主摆臂10的第一端端面a1向第二端b的方向形成有凹陷部，凸出部12设置在凹陷部上，且凸出部12的一端伸出凹陷部的表面的情况下，图9所示的滑槽支架和止位部也可以相适配，并利用设置在轴盖30上的止位部40与凸出部12配合进行防脱止位。需要说明的是，通过本申请实施例提供的凸出部12和止位部40的设置位置，本领域技术人员可以结合具体的情况和需求对滑槽支架20上的滑道22做适应性的结构调整，具体的结构也应均位于本申请实施例的保护范围之内。
参照图10和图11所示，止位部40朝向滑道22的一侧具有第一端面41，在主摆臂10从展开位置转动到闭合位置时，凸出部12抵接在第一端面41上。止位部40还包括与第一端面41连接的第二端面42，在主摆臂10转动至展开位置时，主摆臂10朝向轴盖30的第一侧面抵接于第二端面42。这样，在主摆臂10从闭合位置转动至展开位 置后，止位部40的第二端面42还可以起到对主摆臂10的限位作用，从而防止主摆臂10转动过度，对其他零部件造成损伤。在一种实现方式中，止位部40的第二端面42可以垂直于止位部40的第一端面41。这样，使得主摆臂10闭合位置和展开位置之间可以转动90度，更加符合用户的实际使用需求和体验。在其他实现方式中，第二端面42与第一端面41也可以呈大于90度的夹角，其中夹角的开口方向朝向轴盖30底面。具体可以根据情况和经验进行调整，本申请实施例对此不作具体限定。
在一种实现方式中，如图10和图11所示的转动机构的组装顺序为：先将主摆臂10安装在滑槽支架20上，再将滑槽支架20连同主摆臂10一起整体安装在轴盖30上。其中，安装主摆臂10时，可以将主摆臂10的滑动部11对准滑槽21的入口，并将凸出部12对准滑道22后，将滑动部11和凸出部12对应滑入滑槽21和滑道22即可完成安装。在安装在轴盖30上之后，止位部40会与凸出部12相配合，从而防止主摆臂10的滑动部11从滑槽21脱出。这样，本申请实施例提供的滑槽支架20设计为一体式结构，且开设有与凸出部12相适配的滑道22，凸出部12设置在主摆臂10沿长度方式相对的两端中的第一端端面a1上，止位部40设置在轴盖30上，通过凸出部12的适配设计可以保证设有凸出部12的主摆臂10能够装入至一体式结构的滑槽支架20内，使得凸出部12在主摆臂10闭合后与止位部40配合，如此，转动机构整体零件数量少，方便组装，而且也可以避免滑槽支架20上形成的滑槽21由于装配问题造成的宽度增大的情况，从而使得滑槽21与主摆臂10配合间隙适中，主摆臂10在滑动的过程不易晃动，提高用户体验。
图12是本申请实施例提供的另一种主摆臂的结构示意图。图13是本申请实施例提供的另一种滑槽支架和止位部的结构示意图。图14是图12和图13所示的结构组装后所形成的转动机构在闭合状态的结构示意图，其中，视图c为转动机构在闭合状态的立体结构图，视图d为转动机构在闭合状态的剖面结构图。图15是图14所示转动机构在展开状态的结构示意图，其中，视图e为转动机构在展开状态的立体结构图，视图f为转动机构在展开状态的剖面结构图。参照图12至图15所示，在另一种实现方式中，主摆臂10包括两个滑动部11，两个滑动部11分别设置在第一端a沿宽度方向相对的两侧。主摆臂10的第一端端面a1向第二端b的方向形成有凹陷部13。凹陷部13靠近第二端b的一端还设置有容纳槽14，容纳槽14与凹陷部13连通。凸出部12嵌设于容纳槽14内，且凸出部12的一端伸出凹陷部13的表面。这样，凸出部12可拆卸地连接在主摆臂10上，使得主摆臂10、滑槽支架20和轴盖30之间的组装方式可以更加灵活，也能够更好地适应一体式结构的滑槽支架20。在一种实现方式中，容纳槽14可以设置在凹陷部13靠近第二端b的一端的中心位置。容纳槽14可以为T型槽，相应地，凸出部12可以为T型块，且T型块的纵边伸出凹陷部13的表面。在其他实现方式中，容纳槽14还可以为一字型槽，或者其他形状，本申请实施例对此不作具体限定。凸出部12可以焊接在容纳槽14中，也可以通过其他方式嵌设于容纳槽14内，本申请实施例对此不作限定。
参照图13所示，图13所示的滑槽支架20和止位部40可以与图12所示的主摆臂10相适配。在一种实现方式中，滑槽支架20朝向主摆臂10的一侧表面形成有凸台23，凸台23向内凹陷形成滑道22，滑道22可以包括滑道内底壁221、沿凸出部12的滑动方向相对设置的开口端222和滑道端壁223，滑道内底壁221位于开口端222与滑 道端壁223之间，凸出部12用于在滑动部11沿滑槽21往复滑动时沿滑道内底壁221活动。滑道22将凸台23分隔为第一凸起231和两个第二凸起232。两个第二凸起232相对设置在第一凸起231的两侧，第一凸起231和两个第二凸起232共同围合成滑道22，其中，第一凸起231被配置为止位部40，第一凸起231朝向滑道22的一侧为滑道端壁223。与图13的滑槽支架20相适配，图12所示的主摆臂10上的凹陷部13用于在凸出部12往滑道22内滑动时避让第二凸起232。另外主摆臂10上还形成有避让孔15，第一凸起231用于在主摆臂10处于展开位置时穿设于避让孔15。避让孔15的尺寸和形状可以根据第一凸起231的尺寸和形状来确定，本申请实施例不作具体限定。这样，止位部40设置在滑槽支架20上，有利于轴盖30的标准件加工，另外第二凸起232的弧面可以设置的较长且与主摆臂10的凹陷部13底面的转动轨迹相适配，从而增加主摆臂10转动时与滑槽支架20的滑动配合面积，使得主摆臂10的转动可以更加顺畅，用户体验更佳。
参照图14和图15所示，第一凸起231被配置为止位部40，第一凸起231朝向滑道22的一侧为滑道端壁223，也就相当于止位部40的第一端面41。在主摆臂10从展开位置转动到闭合位置时，凸起部12抵接在第一端面41上。在主摆臂10转动至展开位置时，主摆臂10朝向轴盖30的第一侧面抵接于滑槽支架20边缘背向轴盖30的顶面。这样，即使设置了第一凸起231，也不会限制主摆臂10的展开位置。
在一种实现方式中，如图14和图15所示的转动机构的组装顺序为：先将滑槽支架20安装在轴盖30上，再将不含凸起部12的主摆臂10安装在滑槽支架20上，在将主摆臂10的滑动部11对应滑入滑槽21以后，最后将凸起部12嵌设在容纳槽14内，从而完成安装。在安装完成之后，凸起部12与第一凸起231朝向滑槽21的端面(即滑道端壁223)相抵接，从而防止主摆臂10的滑动部11从滑槽21脱出。这样，本申请实施例提供的滑槽支架20设计为一体式结构，还具有凸台23，凸台23向内凹陷形成与凸起部12适配的滑道22，从而增加主摆臂10转动时与滑槽支架20的滑动配合面积，使得主摆臂10的转动可以更加顺畅，用户体验更佳，而且凸出部12可拆卸地设置在主摆臂10凹陷部13的容纳槽14内，第一凸起231被配置为止位部40，通过可拆卸式的凸出部12的适配设计可以保证设有凸出部12的主摆臂10能够装入至具有凸台23的一体式结构的滑槽支架20内，使得凸出部12在主摆臂10闭合后与止位部40配合，整体转动机构的结构巧妙，易于组装，具有较强的实用性。
如此，本申请实施例提供的转动机构，凸出部设置在主摆臂沿长度方式相对的两端中的第一端端面上，止位部设置在轴盖和滑槽支架的其中一个上，滑槽支架为一体式结构，且开设有与凸出部相适配的滑道，一方面，保证了设有凸出部的主摆臂能够装入至一体式结构的滑槽支架内，使得凸出部在主摆臂闭合后与止位部配合，而确保主摆臂不会脱出滑槽支架与轴盖的组装结构中，另一方面，整体零件数量少，方便组装，而且也可以避免滑槽支架上形成的滑槽由于装配问题造成的宽度增大的情况，从而使得滑槽与主摆臂配合间隙适中，主摆臂在滑动的过程不易晃动，提高用户体验。
另外，本申请实施例提供的可折叠的电子设备，采用的转动机构的滑槽支架为一体式结构，凸出部设置在主摆臂沿长度方式相对的两端中的第一端端面上，止位部设置在轴盖和滑槽支架的其中一个上，整体零件数量少，方便组装，而且也可以避免滑槽支架上形成的滑槽由于装配问题造成的宽度增大的情况，从而使得滑槽与主摆臂配合间隙适 中，主摆臂在滑动的过程不易晃动，提高用户体验。
容易理解的是，本领域技术人员在本申请提供的几个实施例的基础上，可以对本申请的实施例进行结合、拆分、重组等得到其他实施例，这些实施例均没有超出本申请的保护范围。
以上的具体实施方式，对本申请的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上仅为本申请的具体实施方式而已，并不用于限定本申请的保护范围，凡在本申请的技术方案的基础之上，所做的任何修改、等同替换、改进等，均应包括在本申请的保护范围之内。
