第一方面，本申请提供一种可折叠机构，包括基座、第一摩擦件、第一摆臂和按键，第一摩擦件安装于基座的内侧，第一摆臂包括第一转动部和第一凸起部，第一转动部转动连接基座，且位于第一摩擦件的顶侧，并与第一摩擦件相对设置，第一凸起部设于第一转动部的表面，且环绕第一转动部的转动中心设置，按键安装于基座，且可相对基座在第一位置和第二位置之间移动；
可折叠机构处于悬停角度范围内，且按键处于第一位置时，第一凸起部与第一摩擦件间隔设置；
可折叠机构处于悬停角度范围内，且按键处于第二位置时，第一凸起部与第一摩擦件相互摩擦。
本申请所示可折叠机构中，按键可相对基座在第一位置和第二位置之间移动，若不需要使用悬停功能，可将按键拨动至第一位置，在开合可折叠机构至悬停角度范围内时，第一凸起部与第一摩擦件间隔设置，第一摩擦件不会与第一摆臂的第一凸起部接触，即，第一摩擦件不会对第一摆臂相对基座的转动造成干涉，可折叠机构的开合顺畅，有助于改善可折叠终端的开合手感，提高用户的使用体验。
当需要使用悬停功能时，可将按键拨动至第二位置，在开合可折叠机构至悬停角度范围内时，第一凸起部与第一摩擦件发生接触且相互摩擦，第一凸起部与第一摩擦件之间产生的摩擦力能够使第一摆臂保持一定的角度，从而使可折叠机构达到悬停效果。
一种实施方式中，第一摩擦件包括装配部、摩擦部和自由部，装配部安装于基座，摩擦部固定连接于装配部的一侧，且与第一转动部相对设置，自由部固定连接于摩擦部背离装配部的一侧；
基座设有滑动孔，滑动孔连通基座的内侧和外侧，且与按键相对设置；
可折叠机构还包括支撑块，支撑块穿设于滑动孔，且固定连接于按键，并可在按键的带动下相对基座移动；
按键处于第一位置时，支撑块与自由部错位设置，摩擦部与第一凸起部间隔设置。其中，摩擦部可相对基座处于水平状态，摩擦部与第一转动部之间的距离较大，第一摆臂相对基座转动的过程中，第一凸起与摩擦部之间不会接触，保证了第一摆臂相对基座转动的流畅性。
可折叠机构处于悬停角度范围内，且按键处于第二位置时，支撑块抵接自由部，摩擦部与第一凸起部相互摩擦。其中，摩擦部相对基座处于倾斜状态，摩擦部与第一转动部之间的距离较小，第一摆臂相对基座转动的过程中，第一凸起部与摩擦部之间会发生接触而相互摩擦，第一凸起部与摩擦部之间产生摩擦力可将第一摆臂维持在一定角度，从而实现可折叠机构的悬停效果。
一种实施方式中，支撑块包括背离按键的支撑面，支撑块设有止挡部，止挡部设于支撑块背离按键的一侧，且相对支撑面凸出；
按键处于第二位置时，支撑面抵接自由部，止挡部位于自由部朝向第一位置的一侧。
在按键自第一位置朝向第二位置移动时，止挡部可止挡摩擦件的自由部，避免按键移动距离过大而无法导致支撑块无法支撑自由部的问题，保证可折叠机构在不实现悬停功能和使用悬停功能之间切换时的可靠性。
一种实施方式中，支撑块还包括过渡面，过渡面与支撑面连接，沿第一位置向第二位置的方向上，过渡面与支撑面之间的距离越来越大，按键处于第一位置时，过渡面位于支撑面朝向自由部的一侧。

一种实施方式中，基座设有限位部，限位部设于基座的内侧，限位部包括限位部分，限位部分位于自由部的顶侧，且与自由部相对设置。
限位部可限制自由部朝向限位部的方向的运动距离，避免自由部发生较大形变而影响第一摆臂相对基座的转动，保证第一摆臂相对基座的转动顺畅性，有助于提高可折叠终端的开合手感，提升用户的使用体验。
一种实施方式中，可折叠机构还包括第二摆臂，第二摆臂包括第二转动部，第二转动部转动连接基座，可折叠机构在展开状态和折叠状态之间切换时，第一摆臂相对基座的转动方向为第一方向，第二摆臂相对基座的转动方向为第二方向，第二方向与第一方向相反。
可折叠机构在展开状态和折叠状态之间切换时，若第一摆臂相对基座沿逆时针方向转动，则第二摆臂相对基座沿顺时针方向转动，若第一摆臂相对基座沿顺时针方向转动，则第二摆臂相对基座沿逆时针方向转动。
需要说明的是，第一摆臂和第二摆臂均可相对基座转动，有助于保证可折叠机构在折叠状态和展开状态之间切换时的转动稳定性。可以理解的是，在其他一些实施例中，可折叠机构可以只包括第一摆臂，而不包括第二摆臂，或者，可折叠机构可以只包括第二摆臂，而不包括第一摆臂，即，可折叠机构也可以只有一侧可相对基座摆动，本申请对此不做具体限制。
一种实施方式中，可折叠机构还包括第二摩擦件，第二摩擦件安装于基座的内侧，且位于第二转动部的底侧，并与第二转动部相对设置，第二摆臂还包括第二凸起部，第二凸 起部设于第二转动部的表面，且环绕第二转动部的转动中心设置；
可折叠机构处于悬停角度范围内，且按键处于第一位置时，第二凸起部与第二摩擦件间隔设置；

本申请中，利用按键、第一摩擦件和第一摆臂的第一凸起部之间的结构配合、以及第二摩擦件和第二摆臂的第二凸起部之间的结构配合来使实现可折叠终端的悬停功能，可折叠机构的结构简单、体积小且成本低，而且，用户在使用悬停功能和不使用悬停功能时的切换操作简单，可通过拨动按键快读实现悬停功能切换，有助于提高用户的使用体验。
一种实施方式中，可折叠机构还包括同步组件，同步组件安装于基座，且用于带动第一摆臂和第二摆臂相对基座同步转动。
一种实施方式中，可折叠机构包括阻尼组件，阻尼组件包括第一转动轴、第二转动轴、第一弹性件、第二弹性件、阻尼支架、第一摆臂和第二摆臂，第一转动轴、第二转动轴、第一弹性件、第二弹性件和阻尼支架均安装于基座的内侧，第一转动轴和第二转动轴间隔且相对设置，阻尼支架套设于第一转动轴和第二转动轴，第一弹性件和第二弹性件位于阻尼支架的同一侧，第一弹性件套设于第一转动轴，第二弹性件套设于第二转动轴，第一摆臂套设于第一转动轴，且与阻尼支架分别抵接第一弹性件的相对两端，并与阻尼支架铰接，第二摆臂套设于第二转动轴，且与阻尼支架分别抵接第二弹性件的相对两端，并与阻尼支架铰接。

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、完整地描述。
请参阅图1和图2，图1是本申请实施例提供的可折叠终端1000处于折叠状态下的结构示意图，图2是图1所示可折叠终端1000处于展开状态下的结构示意图。
可折叠终端1000可以为手机、平板电脑、个人计算机、多媒体播放器、电子书阅读器、笔记本电脑、车载设备或可穿戴设备等可折叠的电子产品。本实施例中，可折叠终端1000为可折叠手机。即，可折叠终端1000为可以在折叠状态和展开状态之间切换的手机。
其中，为了便于描述，定义图1所示可折叠终端1000的宽度方向为X轴方向，可折叠终端1000的长度方向为Y轴方向，可折叠终端1000的厚度方向为Z轴方向，X轴方向、Y轴方向和Z轴方向两两相互垂直。示例性的，可折叠终端1000的转动轴线的延伸方向平行于Y轴方向。即，可折叠终端1000能够绕Y轴方向相对展开或相对折叠。
需要说明的是，本申请实施例中所提及的平行和垂直等关于相对位置关系的限定词，均是针对当前工艺水平而言的，而不是数学意义上绝对的严格的定义，允许存在少量偏差，近似于平行和近似于垂直均可以。例如，A与B平行，是指A与B之间平行或者近似于平 行，A与B之间的夹角在0度～10度之间均可。例如，A与B垂直，是指A与B之间垂直或者近似于垂直，A与B之间的夹角在80度～100度之间均可。
其中，图1所示可折叠终端1000处于折叠状态。此时，可折叠终端1000沿X轴方向上的尺寸较小，可折叠终端1000便于携带。图2所示可折叠终端1000处于展开状态。示例性的，图2所示可折叠终端1000的展开角度α为180度。换言之，图1所示可折叠终端1000处于展平状态。此时，可折叠终端1000沿X轴方向上的尺寸较大，可折叠终端1000具有较大的显示面积。
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所示可折叠终端1000的展开角度α为为180度是指，α可以为180度，也可以大约为180度，比如170度、175度、185度和190度等。后文中举例说明的角度可做相同理解。
应当理解的是，本申请实施例所示可折叠终端1000为可发生一次折叠的终端。在其他一些实施例中，可折叠终端1000也可以为可发生多次(两次以上)折叠的终端。此时，可折叠终端1000可以包括多个部分，相邻两个部分可相对靠近折叠至可折叠终端1000处于折叠状态，相邻两个部分也可相对背离展开至可折叠终端1000处于展开状态。
请一并参阅图3，图3是图2所示可折叠终端1000的分解结构示意图。
可折叠终端1000包括可折叠装置100和显示屏200，显示屏200安装于可折叠装置100。显示屏200包括背离可折叠装置100的显示面201，显示面201用以显示文字、图像或视频等信息。本实施例中，显示屏200包括第一显示部分210、第二显示部分220和可折叠部分230，可折叠部分230连接于第一显示部分210和第二显示部分220之间。其中，可折叠部分230可绕Y轴方向发生弯折。
如图1所示，可折叠终端1000处于折叠状态时，可折叠装置100和显示屏200均处于折叠状态，第一显示部分210和第二显示部分220相对设置，可折叠部分230发生弯折。此时，显示屏200的外露面积比较少，可大大降低显示屏200被损坏的概率，实现对显示屏200的有效保护。
如图2所示，可折叠终端1000处于展平状态时，可折叠装置100和显示屏200均处于展平状态，第一显示部分210和第二显示部分220相对展平，可折叠部分230不发生弯折而展平。此时，第一显示部分210和第二显示部分220之间的夹角、第一显示部分210和可折叠部分230之间的夹角、以及二显示部分220和可折叠部分230之间的夹角均为α，显示屏200具有大面积的显示区域，实现可折叠终端1000的大屏显示，提高用户的使用体验。
应当理解的是，本申请实施例所示可折叠终端1000采用向内折叠的方式进行折叠，可折叠终端1000处于折叠状态时，显示屏200位于可折叠装置100的内侧。在其他一些实施例中，可折叠终端1000也可以采用向外折叠的方式进行折叠，可折叠终端1000处于折叠状态时，显示屏200位于可折叠装置100的外侧。
请参阅图3和图4，图4是图3所示可折叠终端1000中可折叠装置100的分解结构示意图。
可折叠装置100包括第一壳体110、第二壳体120以及可折叠机构130，可折叠机构130连接于第一壳体110和第二壳体120之间，以实现第一壳体110和第二壳体120之间的转 动连接。具体的，第一壳体110承载第一显示部分210，第二壳体120承载第二显示部分220。换言之，第一显示部分210安装于第一壳体110，第二显示部分220安装于第二壳体120。其中，可折叠机构130与可折叠部分230相对设置。
第一壳体110和第二壳体120可通过可折叠机构130相对转动，使得可折叠装置100在折叠状态和展开状态之间相互切换。具体的，第一壳体110和第二壳体120可相对转动至相对设置，以使可折叠装置100处于折叠状态，如图1所示。此时，可折叠机构130处于折叠状态。第一壳体110和第二壳体120也可相对转动至相对展平，以使可折叠终端1000处于展平状态，如图2所示。此时，第一壳体110和第二壳体120之间的夹角为α，可折叠机构130处于展平状态。
第一壳体110设有第一收容槽1101，第一收容槽1101位于第一壳体110朝向第二壳体120的一侧。第一收容槽1101的开口位于第一壳体110的顶面。第一收容槽1101自第一壳体110的顶面向底面的方向凹陷，且贯穿第一壳体110朝向第二壳体120的侧面。其中，第一壳体110朝向第二壳体120的侧面即为第一壳体110的左侧面。
需要说明的是，本申请实施例描述可折叠终端1000时所采用“顶”、“底”、“左”、“右”、“前”和“后”等方位用词主要依据可折叠终端1000于附图2中的展示方位进行阐述，以朝向Z轴正方向为“顶”，以朝向Z轴负方向为“底”，以朝向X轴正方向为“右”，以朝向X轴负方向为“左”，以朝向Y轴正方向为“后”，以朝向Y轴负方向为“前”，其并不形成对可折叠终端1000于实际应用场景中的方位的限定。
此外，第一壳体110还设有第一安装部140，第一安装部140设于第一收容槽1101的槽底壁面，且位于第一壳体110朝向第二壳体120的侧面和第一收容槽1101的槽侧壁面之间，并与第一壳体110朝向第二壳体120的侧面和第一收容槽1101的槽侧壁面均间隔设置。具体的，第一安装部140自第一收容槽1101的槽底壁面朝向第一收容槽1101的开口的方向延伸。示例性的，第一安装部140成方形块状，第一安装部140的长度方向平行于Y轴方向。
其中，第一安装部140包括第一侧面和第二侧面，第一侧面为第一安装部140背离第一收容槽1101的槽侧壁面的表面，第二侧面与第一侧面相背设置。第一安装部140设有第一滑孔1401，第一滑孔1401的开口位于第一侧面。其中，第一滑孔1401自第一侧面朝向第二侧面的方向凹陷，且贯穿第二侧面。
第二壳体120和第一壳体110的结构相同，且相对可折叠机构130镜像对称。第二壳体120设有第二收容槽1201，第二收容槽1201位于第二壳体120朝向第一壳体110的一侧。第二收容槽1201的开口位于第二壳体120的顶面。第二收容槽1201自第二壳体120的顶面向底面的方向凹陷，且贯穿第二壳体120朝向第一壳体110的侧面。其中，第二壳体120朝向第一壳体110的侧面即为第二壳体120的右侧面。此外，第二壳体120还设有第二安装部150，第二安装部150设有第二滑孔1501。需要说明的是，第二安装部150和第二滑孔1501的结构可分别参照上述第一安装部140和第一滑孔1401的相关描述，在此不再赘述。
可折叠装置100处于展平状态时，即第一壳体110和第二壳体120之间的夹角为α时，第一壳体110的第一收容槽1101和第二壳体120的第二收容槽1201围合形成收容空间 1301。可折叠机构130安装于收容空间1301，且与第一壳体110和第二壳体120均滑动连接。其中，部分可折叠机构130安装于第一壳体110的第一收容槽1101，且与第一安装部140滑动连接，部分可折叠机构130安装于第二壳体120的第二收容槽1201，且与第二安装部150滑动连接。
目前，可折叠终端往往采用可折叠机构来实现折叠、展开和悬停。然而，由于使用环境、使用时间和产品批次等因素，现有的可折叠机构在开合的过程中，往往会有卡顿现像，影响用户的使用体验。而且，由于零部件制造公差原因或者长期使用造成零部件磨损的问题，如果可折叠终端展开使用一段时间后调整为悬停状态，悬停状态很有可能无法保持稳定实现，同样会导致可折叠终端在开合过程有卡顿感，影响用户的使用体验。需要说明的是，本申请描述可折叠终端所提及的“开合过程”是指“在折叠状态和展开状态之间切换的过程”。

可折叠机构130由折叠状态进入展平状态时，即可折叠机构130由折叠状态进入展平状态时，也即可折叠终端1000由折叠状态进入展平状态时，每一摆臂50中，每一摆臂50的第一铰接面517的波峰会进入一个第二铰接面811的波谷，同时每一第二铰接面811的波峰也会进入一个摆臂50的第一铰接面517的波谷。此时，两个摆臂50转动产生的阻尼力较小，可以使用户体验到可折叠终端1000展平到位的手感。
两个弹性件82均位于阻尼支架81背离第一铰接面517的一侧，且分别套设于两个转动轴20。其中，两个弹性件82分别为第一弹性件84和第二弹性件85，第一弹性件84套设于第一转动轴21，第一弹性件84的两端分别抵接阻尼支架81和第一摆臂51，第二弹性件85套设于第二转动轴22，第二弹性件85的两端分别抵接阻尼支架81和第二摆臂52。示例性的，弹性件82可为弹簧。两个垫片83可分别位于两个弹性件82背离阻尼支架81的一侧，且分别套设于两个转动轴20，并分别夹持于一个弹性件82和一个摆臂50的第二子转动部516之间。
需要说明的是，本实施例中，两个摆臂50均为可折叠机构130的阻尼摆臂，而不需要增加新的摆臂来实现可折叠机构130的悬停功能，有助于简化可折叠机构130的结构。在其他一些实施例中，两个摆臂50也可以不为可折叠机构130的阻尼摆臂，而为其他可以与第一壳体110和第二壳体120连接的摆臂，本申请对此不做具体限制。
请参阅图11、图12、图14和图15，用户使用本实施例所示可折叠终端1000的过程中，若不需要使用悬停功能，可将按键31拨动至第一位置，两个支撑块32的支撑面322分别相对两个限位部分1162露出，在开合可折叠终端1000时，两个摩擦件40的摩擦部45均不会与两个摆臂50的第一凸起部514接触，即，两个摩擦件40的摩擦部45不会对两个摆臂50的转动造成干涉，可折叠终端1000开合顺畅。
当用户需要使用悬停功能时，可将按键31拨动至第二位置，两个支撑块32的支撑面322可分别抵接两个摩擦件40的自由部44，以使两个摩擦件40的摩擦部45相对基座10倾斜，从而减小两个摩擦件40的摩擦部45与两个摆臂50的第一凸起部514之间的距离，在开合可折叠终端1000至悬停角度范围内时，两个摩擦件40的摩擦部45可分别与两个摆臂50的第一凸起部514接触而发生摩擦，摩擦部45与第一凸起部514产生的摩擦力能够使两个摆臂50保持一定的角度，从而达到悬停效果。
本实施例所示可折叠终端1000的可折叠机构130中，利用按键31、支撑块32、第一摩擦件41和第一摆臂51的第一凸起部514之间的结构配合、以及第二摩擦件42和第二摆臂52的第二凸起部524之间的结构配合来使实现可折叠终端1000的悬停功能，可折叠机构130的结构简单、体积小且成本低，而且，用户在使用悬停功能和不使用悬停功能时的切换操作简单，可通过拨动按键31快读实现悬停功能切换，有助于提高用户的使用体验。
