Description

本申请涉及通信领域，具体而言，涉及一种转轴、终端设备、转轴控制方法、存储介质及电子装置。
背景技术
随着技术的进步，设备厂商研发出了越来越多类型的终端设备。目前，人们对于大屏幕、多任务处理等方面的要求越来越高，双屏设备(例如，双屏手机)应运而生。为了减小设备尺寸，双屏设备中的两个屏幕需要进行折叠，而两个屏幕所在的本体需要通过转轴连接，从而达到可折叠的效果。除此之外，原始的折叠设备，例如包含一个屏幕和一个键盘的设备，同样也需要将两个本体通过转轴连接起来，达到可折叠的效果。随着技术的发展，还可能会出现更多本体的折叠设备，这些本体之间也同样需要转轴进行连接。以上有两个或两个以上本体的折叠设备在本文中均统一成为折叠设备。
图1是相关技术中的转轴结构示意图。相关技术中，对于连接两个本体的转轴，多采用如图1所示的固定不动的转轴结构。如图1所示，该转轴结构通常由压板101A、压板101B及轴体102三个主要部分组成，除此之外，还可以设置有碟簧103、凸轮104A和凸轮104B。

具体实施方式
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
实施例1
图2是根据本申请实施例1的转轴22在固定部21中的转动和平移的示意图，该实施例提供了一种转轴22，该转轴22可以但不限于应用在折叠设备的两个或两个以上本体之间的连接。
所述转轴22可以被安装于固定部21(该固定部21可以是固定设置于折叠设备本体中的固定部)中，如图2所示，所述转轴22在转动的过程 中在所述固定部21中滑动，其中，所述转轴22转动的角度与所述转轴22在所述固定部21中滑动的位移之间存在对应关系。
在将该转轴22应用于具体的折叠设备时，根据折叠设备各个本体的功能及预期实现的折叠及展开效果，可以灵活设置所述转轴22在转动的过程中在所述固定部21中滑动的方向，图2中仅以横向滑动为例。例如，在双屏设备中，如果希望展开后屏幕在同一水平面，可以令所述转轴22在转动的过程中在所述固定部21中沿横向滑动；再例如，如果希望展开后折叠设备的两个或多个本体不在水平面上而是在竖直面上有高低差异，可以令所述转轴22在转动的过程中在所述固定部21中沿纵向滑动；再例如，如果希望展开后折叠设备的两个或多个本体在水平面上的距离发生变化，可以令所述转轴22在转动的过程中在所述固定部21中沿轴向滑动。根据实际的需要，还可以令所述转轴22在转动的过程中在所述固定部21中沿多个方向中的一个或多个方向组合滑动。
在将该转轴22应用于具体的折叠设备时，根据折叠设备各个本体的功能及预期实现的折叠及展开效果，可以对以上的转轴22转动的角度与转轴22在固定部21中滑动的唯一之间存在的对应关系进行不同的设置。以一个双屏设备为例，所述对应关系可以包括以下至少之一：
所述转轴22转动的角度α为0°时，所述转轴22在所述固定部21中滑动的位移为0，优选地，所述转轴22可以完全缩进所述固定部21；
所述转轴22转动的角度α为180°时，所述转轴22在所述固定部21中滑动的位移为最大位移，所述转轴22至少一部分突出所述固定部21；
所述转轴22转动的角度α为0°<α<180°时，所述转轴22在所述固定部21中滑动的位移与角度α满足预设对应关系。
为了便于理解，以下举一个具体点的例子，图3是根据本申请实施例1的转轴22在固定部21中的转动和平移的示例性示意图。在图3中，折叠设备包括两个相对独立的物理结构部分，称为两个本体，分别为第一本体(例如，可以是双屏手机中的A屏)31和第二本体(例如，可以是双 屏手机中的B屏)32。当第二本体32发生相对于第一本体31的翻转移动(该翻转移动为相对的，按照用户使用习惯，也可以是第一本体31发生相对于第二本体32的翻转移动)时，整个转轴结构22将从第一本体32的内部滑动出来，翻转加上滑动，共同完整翻屏的动作。如图3(a)所示，当第一本体31和第二本体32完全折叠时，转轴22转动0°时，转轴22在固定部21中可以位移为0；如图3(b)所示，当第一本体31和第二本体32之间开始翻转，例如，转轴22转动60°时，转轴22在固定部21中可以位移总行程的1/3；如图3(c)所示，当第一本体31和第二本体32之间翻转到互相垂直的位置，即转轴22转动90°时，转轴22在固定部21中可以位移总行程的2/3；如图3(d)所示，当第一本体31和第二本体32完全翻开时，即转轴22转动180°时，转轴22在固定部21中可以位移到最大行程。
该方案摒弃了固定不动的转轴结构，使得转轴22整体所在的位置随着转轴22的转动发生变化，从而能够根据实际使用需要，设计出随着转轴22的翻转带动转轴22在固定部21中的位移发生恰当的变化，从而达到预期的翻转效果，使得折叠设备的两个本体31和32达到所期望的组合状态。该方案可以解决相关技术中固定不动的转轴结构应用到折叠设备中时可能导致机体厚度增加、展开间隙较大、可靠性较低、影响用户使用效果等问题中的至少之一。该方案能够满足折叠设备的翻转设计，且具有需求空间小、不易损坏、可靠性高等优点。
本领域技术人员应当能够理解，以上的效果可以通过多种硬件结构来实现，以下通过实施例的方式给出示例性的实现方式。图4是根据本申请实施例1的转轴结构的示意图。所述转轴22可以包括：轴体221，以及可绕所述轴体221转动的第一转轴压板222和第二转轴压板223。所述第一转轴压板222包括：固定壳体2221、位移控制机构2222及伸缩板2223，其中，
所述固定壳体2221固定安装在所述固定部21中；
所述位移控制机构2222被安装于所述固定壳体2221上，并与所述伸 缩板2223的一端相连接，用于控制所述伸缩板2223在所述固定壳体2221中滑动；
所述伸缩板2223的另一端套装于所述轴体221上。
其中，所述位移控制机构2222与所述伸缩板2223的一端相连接可以保证所述位移控制机构2222能够带动所述伸缩板2223在所述固定壳体2221中平移。在具体实施时，可以采用以下两种连接方式：
连接方式一
一种具体的连接方式可以是所述位移控制机构2222与所述伸缩板2223二者直接连接。为了在所述伸缩板2223滑动到最大位移位置后将其暂时固定卡位，所述固定壳体2221边缘可以设有第一凸出部2228，所述伸缩板2223的侧面设有第二凸出部(可以通过在伸缩板2223的本体上的适当位置设置凸出部，或者可以通过将伸缩板2223的本体的宽度设置为阶梯式来实现)，所述第一凸出部2228与所述第二凸出部相配合，阻挡所述伸缩板2223滑出所述固定壳体2221所形成的空间。
连接方式二
另一种具体的连接方式可以是所述位移控制机构2222与所述伸缩板2223通过一个向内弯曲的转换垫片2224连接，例如，所述位移控制机构2222可以通过所述转换垫片2224与所述伸缩板2223的一端相连接，通过使用该转换垫片2224，能够使得所述位移控制机构2222与所述伸缩板2223在所述固定壳体2221中的放置位置在伸缩板伸缩方向上更加集中。为了防止所述伸缩板2223滑出所述固定壳体2221，可以在所述固定壳体2221边缘向内设有第一凸出部2228，用于阻挡所述转换垫片2224滑出所述固定壳体2221所形成的空间。
按照以上的结构，所述位移控制机构2222能够带动所述伸缩板2223在所述固定壳体2221中平移。如果为了实现更好的效果，使得移动的平滑度更好，可以在该结构中添加一定的缓冲装置，例如，可以在所述转换垫片2224与所述伸缩板2223之间设置有第一弹簧2225，所述转换垫片 2224与所述伸缩板2223之间沿所述第一弹簧2225的伸缩方向滑动连接(可以采用各种滑动连接方式，例如，可以设置一滑轨)。
为了防止所述第一弹簧2225的侧向震颤，所述转换垫片2224面向所述伸缩板2223方向可以延伸出用于约束所述第一弹簧2225侧向运动的片状结构2226，相应地在所述伸缩板2223上与所述片状结构对应的位置开有与所述片状结构相配合的凹槽2227。
为了在所述伸缩板2223滑动到最大位移位置后将其暂时固定卡位，所述固定壳体2221内侧还可以设有相互配合的凸台，用于在所述伸缩板2223缩回所述固定壳体2221达到最大位移时，卡住所述转换垫片2224。在所述伸缩板2223从滑动状态进入最大位移位置、或从最大位移位置向回滑动的情况下，在所述位移控制机构2222作用于所述伸缩板2223的力的作用下，该相互配合的凸台可以被突破(即该凸台可以被越过而不再承担卡位功能)。可以采用模拟和/或实验的方式，通过调整凸台的高度、弧度和/或所述位移控制机构2222的作用力来实现这一效果。
所述位移控制机构2222主要用于实现根据控制信号，带动所述伸缩板2223在所述固定壳体2221中滑动。所述位移控制机构2222可以用于接收基于所述第一转轴压板222和第二转轴压板223之间的夹角产生的控制信号，并根据所述控制信号带动所述伸缩板2223按照与所述夹角对应的位移在所述固定壳体2221中滑动。在具体实现中，可以有多种结构来实现这一预期效果。例如，转轴22伸缩的过程可以依靠的电磁及弹簧机构，还可以使用马达、液压方式提供动力，配合霍尔器件增加角度传感器，当角度传感器感应到翻盖打开的状态后，根据打开的角度，实时反馈给电机、液压机构信号，电机、液压机构驱动转轴22进行伸缩的动作。以下分别进行说明。

实施例7
该实施例中，详细描述了采用位移控制机构2222实现结构一时，转轴翻出过程和闭合动作中各个部件的运作过程。该实施例中以霍尔开关作为角度传感器为例进行了描述。
该实施例中，第一转轴压板22包括：伸缩板2223；转换垫片2224；第二弹簧22223；第一弹簧2225；固定壳体2221；第一磁铁22221；第二磁铁22222几个部分组成。固定壳体2221的空间承载伸缩板2223、转换 垫片2224、第二弹簧22223、第一弹簧2225，同时要与整机连接。第一磁铁22221贴在固定壳体2221的特定位置。转换垫片2224装配到固定壳体2221内，第二弹簧22223在转换垫片2224与固定壳体2221内；第一弹簧2225放置在伸缩板2223与转换垫片2224内。
可见，在该实施例中，在一侧压板上通过由霍尔开关控制的磁铁驱动内置弹簧来达到伸缩整个转轴的目的。霍尔开关判断转轴未被打开时，整个转轴内置在壳体中，当霍尔开关判断转轴开始翻转时，触发电磁铁，从而推动转轴向外移动，当霍尔开关判断转轴开始闭合时，反向位触发电磁铁，使转轴在翻转闭合的过程中闭合。
图11是根据本申请实施例7的第一本体和第二本体翻转闭合时转轴内部的部件的运动方向示意图。
如图11所示，当霍尔开关接受到闭合信号确认物理结构部分31和32即第一本体31和第二本体32，即将翻转闭合时，驱动第一磁铁22221产生磁性吸引第二磁铁22222向图11箭头方向运动，由于第二磁铁22222及第二弹簧22223和转换垫片2224固定在一起，此时转换垫片2224也向图11中箭头方向运动，同时第一弹簧2225压缩，推动伸缩板2223向图11箭头所示的相反方向运动，因为第二弹簧22223的力量大于伸缩板内弹簧的力量，所以整体上面伸缩板2223是向图11箭头所示方向运动的，这样伸缩板2223实现了缓慢的向图11所示方向运动。伸缩板2223进入到固定壳体2221的空间中，当运动动作结束后。转换垫片2224进入到固定壳体2221的凸台中，卡住转换垫片2224。转换垫片2224完成了缩回的动作。图12是根据本申请实施例7的第一本体和第二本体翻转闭合最终状态示意图。
图13是根据本申请实施例7的第一本体和第二本体翻转打开时转轴内部的部件的运动方向示意图。
如图13所示，当霍尔开关接受到关闭信号确认物理结构部分31和32，即第一本体31和第二本体32，即将翻转打开时，第一磁铁22221产生磁 性推动第二磁铁22222向图13所示箭头方向运动，由于第二磁铁22222及第二弹簧22223和转换垫片2224固定在一起，此时转换垫片2224也向图13中箭头方向运动，同时第一弹簧2225伸长，推动伸缩板2223向图13箭头所示的相反方向运动，因为第二弹簧22223的力量大于伸缩板内弹簧的力量，所以整体上面伸缩板2223是向图13箭头所示方向运动的，这样伸缩板2223实现了缓慢的向图13所示方向运动。当运动动作结束后。第二磁铁22222进入到固定壳体2221的凸台中被凸台卡住，转换垫片2224完成了伸出的动作。图14是根据本申请实施例7的第一本体和第二本体翻转不完全打开中间状态示意图。

当角度传感器检测到夹角的变化后，处理器会产生信号，发出指令使电动马达22224通电转动，由于电动马达22224和齿条22225相互啮合，在电动马达22224转动的过程中齿条做水平的移动，又由于齿条22225和伸缩板2223是固定在一起的，所有在电动马达22224转动的过程中，伸缩板2223做水平的移动，实现转轴在固定部21中的移动。
实施例9
该实施例中，详细描述了采用位移控制机构2222实现结构三时，转轴移动的运作过程。
第一本体31上设一开放的容纳部(对应于上述固定部21)用于容纳转轴22的第一转轴压板222，所述第一转轴压板222包括：固定壳体2221、位移控制机构2222及伸缩板2223。位移控制机构2222可以是液压泵(液压驱动装置22226的一个实例)和液压杆(传动杆22227的一个实例)的结合。液压杆可以水平伸缩，液压杆4和伸缩板2223两者刚性连接，连接方式为焊接，铆接，或螺栓连接.
当角度传感器检测到夹角的变化后，处理器会产生信号，发出指令使液压泵通电，液压泵使液压油进入到液压杆中推动液压杆伸缩运动，由于液压杆和伸缩板2223是固定在一起的，所以在液压杆运动的过程中带动伸缩板2223做水平的移动，实现转轴在固定部21中的移动。
实施例10
本实施例描述了在采用不同位移控制机构的实现结构的情况下，控制信号的产生过程及控制信号的具体形式。需要说明的是，以下内容仅仅用于理解本申请，并不构成对本申请的限定。
对于位移控制机构2222实现结构一
当第一本体和第二本体之间的夹角变化时，角度传感器会检测到这个变化，然后产生一个控制信号到处理器，处理器发出指令给电磁铁通电，使电磁铁产生磁性(N极或S极)，具体为转轴伸出时和弹簧连接磁铁的极性相反，转轴缩回时和弹簧连接磁铁的极性相同，弹簧驱动的形式下，弹簧选定后，弹力也就确定下来。磁性的大小根据弹簧弹力的大小改变电流的大小来调整，使磁铁的相互驱动力大于弹簧的弹力。
对于位移控制机构2222实现结构二
第一本体和第二本体之间的夹角变化时，角度传感器会检测到这个变化，然后产生一个控制信号到处理器，处理器发出指令给电机通电，调整通电电流的大小来改变电机的转速。即可调整齿条的移动速度，对应关系为0-180°对应整个转轴的位移从零到最大，角度和位移可分为任意相等的份数(如简单分成三份，即夹角0°时位移为零，夹角60°时位移为1/2, 夹角180°时，位移最大)。
对于位移控制机构2222实现结构三
和电机控制方式类似，第一本体和第二本体之间的夹角变化时，角度传感器会检测到这个变化，然后产生一个控制信号到处理器，处理器发出指令给液压泵(液压泵也可以看成是一个电机)，通过控制电流的大小调整液压泵中液体的体积来驱动液压杆(此处液压杆类似于电机控制方式中的齿条)带动转轴进行移位。
根据本申请，转轴转动的同时转轴在固定部中可以同步滑动，转轴转动的角度和转轴在固定部中的位移有相互的对应关系。该方案摒弃了固定不动的转轴结构，使得转轴整体所在的位置随着转轴的转动发生变化，从而能够根据实际使用需要，设计出随着转轴的翻转带动转轴在固定部中的位移发生恰当的变化，从而达到预期的翻转效果，使得折叠设备的两个本体达到所期望的组合状态。该方案可以解决相关技术中固定不动的转轴结构应用到折叠设备中时可能导致机体厚度增加、展开间隙较大、可靠性较低、影响用户使用效果等问题中的至少之一。该方案能够满足折叠设备的翻转设计，且具有需求空间小、不易损坏、可靠性高等优点。
显然，本领域的技术人员应该明白，上述的本申请的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本申请不限制于任何特定的硬件和软件结合。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护 范围之内。
