具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施方式中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本申请的具体实现方式构成任何限定，各个实施例在不矛盾的前提下可以相互结合相互引用。
现有柔性屏终端的可折叠柔性屏长度固定，柔性屏在展平和折叠过程中会被拉伸和挤压，进而导致柔性屏受到拉力和压力而容易损伤，缩短柔性屏使用寿命。本申请部分实施例的目的在于提供一种可折叠终端，其柔性屏在折叠和展平过程中不会被拉伸和挤压，延长柔性屏使用寿命。
本申请的第一实施方式涉及一种可折叠终端，该终端可以是任何终端设备，如手机、平板电脑、笔记本电脑、可穿戴设备等。
如图1所示，可折叠终端包括柔性屏1、第一收纳转轴2、第二收纳转轴3、折叠转轴4、第一壳体5以及第二壳体6。柔性屏1的一端连接固定于第一收纳转轴2，柔性屏1部分缠绕 于第一收纳转轴2上。当柔性屏1弯曲折叠或展开时，第一收纳转轴2进行旋转，以释放或卷起柔性屏1。第一收纳转轴2与第二收纳转轴3平行并列设置，柔性屏1的另一端连接固定于第二收纳转轴3，柔性屏1部分缠绕于第一收纳转轴2和第二收纳转轴3中的至少一者上。柔性屏1折叠时，第一收纳转轴2进行旋转以释放柔性屏1；当柔性屏1展开时，第二收纳转轴3进行旋转以卷起柔性屏1，使两个转轴交替实现释放、卷起动作，满足无限次折叠过程中的柔性1长度调节。第一收纳转轴2的边缘与第一马达10相连，马达10通过驱动第一收纳转轴2的端部旋转，以带动第一收纳转轴2进行旋转，第二收纳转轴3的边缘与第二马达11相连，马达11通过驱动第二收纳转轴3的端部旋转，以带动第二收纳转轴3进行旋转，如图2所示。
需要说明的是，第一收纳转轴2与第二收纳转轴3均为双向旋转转轴，使得第一收纳转轴2与第二收纳转轴3可以随时正转或者反转，以交替进行释放、卷起动作。
需要说明的是，第一壳体5和第二壳体6经由折叠转轴4枢转连接，折叠转轴4处于第一壳体5和第二壳体6之间，使得第一壳体5和第二壳体6均可以绕折叠转轴4进行旋转，第一收纳转轴2设于第一壳体5内部空间内，第二收纳转轴3设于第二壳体6内部空间内。为了便于理解和说明，本实施例以第一收纳转轴2设于第一壳体5内部空间的边缘位置、第二收纳转轴3设于第二壳体6内部空间的边缘位置为例，以使第一收纳转轴2、第二收纳转轴3之间留有较大的空间放置其他元件，本实施例不对第一收纳转轴2、第二收纳转轴3在第一壳体5、第二壳体6内部空间的位置做具体限制。
如图1所示，初始状态下柔性屏1大部分缠绕于第一收纳转轴2，少部分缠绕于第二收纳转轴3，可折叠终端从展平状态开始折叠至折叠状态的过程如图3所示，，此时第一收纳转轴2在使用者左侧，第二收纳转轴3在使用者右侧，柔性屏1朝向上方，第一壳体5绕折叠转轴4逆时针转动。柔性屏1绕折叠转轴4发生弯曲折叠，柔性屏1的弯曲折叠区域由于弯曲拉伸，柔性屏1受到的拉力逐渐增大，第一马达10带动第一收纳转轴2顺时针转动，释放部分长度的柔性屏1，使柔性屏1的表面长度增加，以缓解柔性屏1受到的拉力，从而使柔性屏1不会受到损伤，最终折叠至如图4示的状态。
如图5所示，当需要展平时，可折叠终端从折叠状态开始展平至展平状态，第一壳体5绕着折叠转轴4顺时针转动。在从折叠到展平的过程中，原本拉长的柔性屏1又趋于变短，柔性屏1受到的两侧的挤压力逐渐增大，第二马达11带动第二收纳转轴3顺时针转动，同时逐渐将柔性屏1缠绕在第二收纳转轴3上，使柔性屏1的表面长度减少，以缓解柔性屏1受到的压力，从而使柔性屏1不会受到损伤，最终展平至如图6所示的状态。
如图7所示，当再次需要折叠时，具有柔性屏的可折叠终端的左半部分即第一壳体5绕着折叠转轴4逆时针转动。在从展平到折叠的过程中，柔性屏1受到的拉力逐渐增大，第一马达10带动第一收纳转轴2顺时针转动，释放部分长度的柔性屏1，使柔性屏1的表面长度增加，以缓解柔性屏1受到的拉力，从而使柔性屏1不会受到损伤，最终折叠至如图8所示的状态。
如图9所示，当再次需要展平时，第一壳体5绕着折叠转轴4顺时针转动。在从折叠到展平的过程中，柔性屏1受到的两侧的挤压力逐渐增大，第二马达11带动第二收纳转轴3顺时针转动，同时逐渐将柔性屏1缠绕在第二收纳转轴3上，使柔性屏1的表面长度减少，保证从折叠到展平的过程中可以缓解柔性屏1受到的压力，从而使柔性屏1不会受到损伤，最终展平至如图10所示的状态。
如图3至图10所示，每经过一次折叠，第一收纳转轴2就会释放一部分缠绕在其上的柔性屏1；再经过一次展平，第二收纳转轴3就会缠绕回收一部分柔性屏1；当第一收纳转轴2上缠绕的柔性屏1全部释放完时，柔性屏1的缠绕部分全部缠绕在第二收纳转轴3上，此时第一马达10、第二马达11转动方向改变，每经过一次折叠，第二收纳转轴3就会释放一部分缠绕在其上的柔性屏1；再经过一次展平，第一收纳转轴2就会缠绕回收一部分柔性屏1，这样循环往复，此外，由于多次折叠、展平过程中柔性屏1从第一收纳转轴2一侧逐步转移到第二收纳转轴3一侧，或从第二收纳转轴3一侧逐步转移到第一收纳转轴2一侧，在转轴转动方向尚未切换期间的每一次弯曲折叠，都是柔性屏1不同的区域进行弯曲，以减少使用固定区域进行弯曲所导致的疲劳损伤。
需要说明的是，为了便于理解和说明，本实施例以柔性屏1围绕折叠转轴4以背离柔性屏的折叠方向进行折叠为例，折叠完成后第一壳体5、第二壳体6相接触。实际应用中还可以选择柔性屏1围绕折叠转轴4相对折叠、即折叠完成后柔性屏1的左右两部分相接触的折叠方式，本实施例不对柔性屏1的折叠方向做具体限制。
综上，本实施例中，通过使用第一收纳转轴2与第二收纳转轴3相互配合，在每一次折叠和展平过程中，轮流对柔性屏1进行释放和卷起，不仅缓解了每一次折叠和展平时柔性屏1由于拉伸和挤压而受到的拉力和压力，还使柔性屏1在第一收纳转轴2与第二收纳转轴3之间循环移动，以改变每次柔性屏1的弯曲区域，解决柔性屏局部疲劳损伤的问题。
本申请的部分实施例，通过将柔性屏缠绕于第一收纳轴，在柔性屏被弯曲折叠过程中通过第一收纳转轴转动释放一定长度的柔性屏、在柔性屏被展开的过程中通过第二收纳转轴转动卷起一定长度的柔性屏，以适时调整柔性屏的长度，实现弯曲折叠的柔性屏在受到拉力时 可以释放柔性屏缓解拉力、在受到压力时可以通过收起柔性屏缓解压力，保护柔性屏不受到损伤，解决在一些情形中柔性屏在展平和折叠时会受到拉力和压力而导致损伤的问题，大大延长柔性屏的使用寿命。
本申请的第二实施方式涉及一种可折叠终端。第二实施方式与第一实施方式大致相同，主要区别之处在于：在本申请第二实施方式中，柔性屏1设有应力检测层7。第一马达10、第二马达11分别与应力检测层7相连，根据应力检测结果控制马达的转动角度，进而控制柔性屏1所释放或回收的长度。
需要说明的是，为了便于理解和说明，本实施例以应力检测层7贴附设置于柔性屏1背面为例，本实施例不对应力检测层7设置方式做具体限制。
如图11所示，当具有柔性屏的可折叠终端从展平到折叠时，柔性屏1受到的拉力逐渐增大，应力检测层7会实时检测柔性屏1受到的拉力，当柔性屏1受到的拉力超过系统设置的安全阈值时，第一马达10会带动第一收纳转轴2转动，同时逐渐释放绕在其上的柔性屏1直至柔性屏1受到的拉力低于系统设置的安全阈值，从而使柔性屏1的表面长度增加，保证从展平到折叠的过程中，柔性屏1受到的拉力始终小于系统设置的安全阈值，从而使柔性屏1不会受到损伤。
当具有柔性屏的可折叠终端从折叠到展平时，柔性屏1受到的两侧的挤压力逐渐增大，应力检测层会实时检测柔性屏1受到的拉力，当柔性屏1受到的挤压力超过系统设置的安全阈值时，第二马达11会带动第二收纳转轴3转动，同时逐渐将柔性屏的缠绕部分缠绕在第二收纳转轴3上直至柔性屏1受到的拉力低于系统设置的安全阈值，使柔性屏1的表面长度减少，保证从折叠到展平的过程中，柔性屏1受到的挤压力始终小于系统设置的安全阈值，从而使柔性屏1不会受到损伤。
本实施例中，通过在柔性屏1背面设置应力检测层7，可以随时监测柔性屏1所受到的应力大小，一旦发现柔性屏1所受应力大于设置的安全阈值时，就会通过第一马达10带动第一收纳转轴2转动或第二马达11带动第二收纳转轴3转动，适时调整柔性屏1，通过使应力检测层与第一马达10、第二马达11相连，根据应力检测的结果对马达进行控制，进而控制第一收纳转轴2和第二收纳转轴3的转动，检测到拉力或压力达到预设值时再放松或收紧柔性屏1，确保在柔性屏1的耐受力范围内实现柔性屏的释放、卷起。
本申请的第三实施方式涉及一种可折叠终端。第三实施方式与第一实施方式大致相同，主要区别之处在于：在本申请第三实施方式中，柔性屏1与第一壳体5、第二壳体6之间的 贴合处有开口缝隙9，开口缝隙9设有硅胶密封层8，硅胶密封层8通过粘胶或点胶等方式与第一壳体5、第二壳体6相连接。柔性屏1一端经由开口缝隙9延伸至第一壳体5内以连接固定于第一收纳转轴2上，柔性屏1另一端经由开口缝隙9延伸至第二壳体6内以连接固定于第二收纳转轴3上。
如图12所示，柔性屏1在与第一壳体5、第二壳体6的贴合处会有接缝空隙，外部空间的水或者灰尘会通过这些接缝空隙进入可折叠终端内部，导致可折叠终端内部元件损坏失灵，造成损失。本实施例中在壳体与柔性屏1的接缝空隙处设置硅胶密封层8，可以将可折叠终端内部空间与外部空间向隔绝，实现防水和防尘的目的。硅胶密封层8通过粘胶或点胶的方式，粘连在第一壳体5、第二壳体6内壁上以密封开口缝隙9，开口缝隙9即为柔性屏1和第一壳体5、第二壳体6内壁之间的空隙。
本实施方式通过在柔性屏1与第一壳体5、第二壳体6之间贴合的开口缝隙9设置硅胶密封层8，保护可折叠终端的内部元件不受外界水及灰尘的污染，更好的延长了可折叠终端的寿命。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内。
本领域的普通技术人员可以理解，上述各实施方式是实现本申请的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本申请的精神和范围。
