具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
参见图1，所示为本发明实施方式一中提供的可弯折终端100处于展开状态的剖视图。该可弯折终端100可以为可弯折的手机、可弯折的平板电脑、可弯曲的显示器等可以弯曲并弯折的各类电子设备。所述可弯折终端100包括柔性显示屏2和可弯折支撑组件1，所述柔性显示屏2包括弯折区22以及非弯折区21，所述弯折支撑组件2包括弯折支撑板112及与弯折支撑板112间隔设置的非弯折支撑板111，所述弯折支撑板112设置于所述柔性显示屏2的弯折区22的背面用于支撑所述弯折区22，且所述弯折支撑板112可相对所述弯折区22滑动，所述非弯折区21固定于所述非弯折支撑板111；当所述柔性显示屏的弯折区22弯折时，所述弯折支撑板112沿朝向非弯折支撑板111的方向相对所述弯折区22滑动。
请一并参照图2，所示为可弯折终端100处于弯折状态的剖视图。柔性显示屏2具有相背设置的正 面和背面，正面为可显示内容的显示面，背面为无法显示内容的非显示面。在本实施方式中，柔性显示屏2包括两个非弯折区21和一个弯折区22，两个非弯折区21分别位于该弯折区22正对的一侧。即弯折区22位于两个非弯折区21之间。当然，在其它实施方式中，柔性显示屏2仅包括一个非弯折区21，非弯折区21位于弯折区22的一侧。
可弯折支撑组件1包括支撑件11、壳体12和滑块13。支撑件11包括一弯折支撑板112和至少一非弯折支撑板111。本实施方式中，所述弯折支撑板112设置于所述柔性显示屏2的弯折区22的背面，用于支撑所述弯折区22的柔性显示屏2，且所述弯折支撑板112可相对所述弯折区22滑动。非弯折支撑板111设置在所述柔性显示屏2的非弯折区21的背面，用于支撑所述非弯折区21的柔性显示屏2。所述非弯折支撑板111可通过光学背胶贴合于所述柔性显示屏2的非弯折区21。在本实施方式中，支撑件11包括一个弯折支撑板112和两个非弯折支撑板111。两个非弯折支撑板111各自分别位于弯折支撑板112正对的一侧。在一实施方式中，两个非弯折支撑板111分别固定连接于弯折支撑板112的一侧，换而言之，支撑件11为一整片的薄金属支撑片。由于所述弯折支撑板112可相对所述弯折区22滑动，故此，当柔性显示屏2弯折时，第二非弯折区21弯折支撑板112的两侧随着柔性显示屏2的弯折而分别朝着柔性显示屏2的非弯折区21滑动。该结构的薄金属片使得柔性显示屏2与弯折支撑板112和非弯折支撑板111装配时，只需要保证两个非弯折支撑板111分别与两个非弯折区21的固定关系即可，而无需考虑两个非弯折支撑板111与弯折支撑板112之间的装配关系，利于装配。
并且,由于是一整块的金属薄片,因而可对柔性显示屏2下方的空间进行密封,防止外界的杂质或水汽进入壳体12内部。在弯折过程中，金属薄片通过变形仍然保持对柔性显示屏2下方空间的密封状态，使得壳体12内部始终保持与外界良好的隔绝。
可以理解的，支撑件11和柔性显示屏2可以形成一个独立的可弯折的显示模组来与其它器件(如壳体12)进行装配以形成具有可弯折性的显示设备。
滑块13设置于所述弯折支撑板112与所述非弯折区21相邻的一侧，用于支撑所述柔性显示屏2的弯折区22。当柔性显示屏1弯折带动弯折支撑板112滑动时，所述弯折支撑板112的弯折驱动所述滑块13朝所述柔性显示屏2的非弯折区21滑动。本实施方式中，滑块13的数量为两个，每一滑块13各自分别与弯折支撑板112针对的两侧固定连接。滑块13整个与弯折支撑板112固定。在另一实施方式中，滑块13部分与弯折支撑板112通过背胶相贴合。设置两个滑块13能够使得弯折支撑板112的两侧在弯折时皆能够通过滑块13的滑动而相应补偿柔性显示屏2的弯折区22与弯折支撑板112之间的长度差。当然，在其它实施方式中，滑块13的数量还可以为一个，一个滑块13可以靠近非弯折支撑板111。
两个滑块13的形状相同。其中，滑块13呈阶梯状，具有主体部131和延伸部132，所述主体部131固设于所述弯折支撑板112的一侧上，所述延伸部132朝着远离所述主体部131的方向延伸。其中，主体部131大致呈矩形块，延伸部132大致呈长条形。在本实施方式中，壳体12开设有导向槽12a。延伸部132收容于壳体12的导向槽12a中。该阶梯状的滑块13可保证滑块13在柔性显示屏2弯折时所述弯折支撑板112能驱动滑块13能平稳地滑动，从而提高了可弯折终端100的弯折可靠性。当然，在其它实施方式中，两个滑块13的形状还可以不相同，例如，靠近一个非弯折支撑板111的滑块13的延伸部132的长度大于靠近另一个非弯折支撑板111的滑块13的延伸部132的长度；另外，两个滑块13的结构还可以不相同，一个滑块13呈阶梯状，一个滑块13可以呈矩形状，等。
壳体12用于支撑非弯折支撑板111，即非弯折支撑板111固设于壳体12上。壳体12包括第一框架121和第二框架123。具体的，两个所述非弯折支撑板111各自固定于所述第一框架121和所述第二框架123上。本实施方式中，两个非弯折支撑板111分别固定于第一框架121和第二框架123上。换言之，所述壳体12与所述非弯折区21正对的位置处设有框架。第一框架121和第二框架123中分别容置有一个滑块13。换言之，当弯折支撑板112弯折时，弯折支撑板112带动两个滑块13分别在第一框架121和第二框架123中滑动。通过所述弯折支撑板112的弯折驱动所述滑块13朝所述非弯折区21滑动，以使所述柔性显示屏2在弯折时所述弯折区22在弯折方向上的长度与所述弯折支撑板112与所述滑块13在所述弯折方向上的长度之和相等。如此，该滑块13在可弯折终端100发生弯折时朝非弯折区21 的滑动可补偿所述弯折支撑板112在弯折过程对柔性显示屏2的拉伸长度进行补偿，避免由于弯折过程中弯折支撑板112被拉扯而损坏，从而提高可弯折支撑组件1和可弯折终端100弯折的可靠性。
请再次参照图1，可弯折支撑组件1还包括与所述滑块13相固定的第一弹性件14。当所述滑块13朝所述柔性显示屏2的非弯折区21滑动时，所述滑块13将挤压所述第一弹性件14使所述第一弹性件14发生形变。请参照图2，当所述弯折支撑板112自弯折状态展开时，所述第一弹性件14形变恢复驱动所述滑块13往所述弯折区22滑动并缩小所述弯折支撑板112与所述滑块13之间在展开方向上的长度之和。本实施方式中，所述第一弹性件14的数量对应滑块13的数量为两个。两个第一弹性件14分别位于第一框架121和一个滑块13之间、和第二框架123和另一个滑块13之间。在可弯折终端100处于弯折状态时，第一弹性件14压缩于框架和滑块13之间，如此，可弯折终端100自弯折状态开始展开时，第一弹性件14驱动滑块13往弯折区22滑动并缩小弯折支撑板112与滑块13在展开方向上的长度之和，换言之，第一弹性件14提供的弹性力能够使得滑块13快速回位。其中，第一弹性件14可以为弹簧。
可弯折支撑组件1还包括形变件15，所述形变件15设置于非弯折支撑板111的局部。本实施方式中，请参照图3和图4，该形变件15设置于非弯折支撑板111靠近弯折支撑板112的一侧。当弯折支撑板112弯折时，滑块13朝柔性显示屏2的非弯折区21的滑动驱动形变件15形变以支撑在弯折状态与所述形变件15正对的柔性显示屏2。本实施方式中，可弯折支撑组件1包括两个形变件15。当弯折支撑板112弯折时，弯折支撑板112相对柔性显示屏2的弯折区22的滑动驱动弯折支撑板112的两侧分别带动一个滑块13朝着两个非弯折支撑板111滑动，使形变件15发生变形，从而实现弯折支撑板112弯折后的长度补偿，防止可弯折终端100在弯折过程中柔性显示屏2被弯折支撑板112拉伸，提高了可弯折终端100的弯折可靠性。
在本实施方式中，所述形变件15夹设在所述弯折支撑板112和所述非弯折支撑板111之间。具体的，每一所述形变件15分别位于一个非弯折支撑板111与弯折支撑板112的连接处、和另一个非弯折支撑板111和弯折支撑板112的连接处。如此，当弯折支撑板112弯折时，滑块13的滑动将快速挤压形变件15，使得滑块13驱动形变件15快速压缩，从而实现弯折支撑板112弯折后的快速长度补偿。当然，在其它实施方式中，形变件15可以与非弯折支撑板111和弯折支撑板112的连接处之间间隔有预设距离，可以理解的，该预设距离需要满足当弯折支撑板112弯折时，滑块13能够挤压形变件15。
在一实施方式中，所述形变件15由所述非弯折支撑板111靠近所述弯折支撑件11的侧边弯折形成，所述形变件15呈凹陷状。可以理解的，该凹陷状为V形、U形或半圆弧形中的至少一种。具体的，非弯折支撑板111的靠近弯折支撑板112的一侧形成一个V形的形变件15。该形变件15在受到滑块13挤压时会变窄，换言之，形变件15发生弹性变形。该结构的形变件15只需在所需位置弯折即可形成，结构简单的同时又具有较佳的变形量。当然，在其它实施方式中，形变件15可以为锯齿形即多个V形连接，或者U形，半圆弧形等。可以理解的，请参照图3和图4，所述可弯折支撑组件1还包括弹性填充件16，所述弹性填充件16填充于所述形变件15。本实施方式中，弹性缓冲件16可以为硅胶、橡胶、泡棉等，通过在形变件15中凹陷空间中进一步设置弹性填充件16，能够使得柔性显示屏2对应形变件15的位置具有更佳的支撑。
请参照图2和图4，可弯折终端100的弯折时各个器件的工作过程为：当弯折支撑板112弯折时，弯折支撑板112相对柔性显示屏2的弯折区22的滑动驱动弯折支撑板112的两侧分别带动一个滑块13朝着两个非弯折支撑板111滑动，使形变件15发生变形，从而实现弯折支撑板112弯折后的长度补偿，防止可弯折终端100在弯折过程中柔性显示屏2被弯折支撑板112拉伸，提高了可弯折终端100的弯折可靠性。
另外，请参照图1和图3，可弯折终端100的展开时各个器件的工作过程为：第一弹性件14驱动滑块13往弯折区22滑动，换言之，第一弹性件14提供的弹性力能够使得滑块13快速回位。另一实施方式中，请参照图5，所述形变件17由弹性材料制成，所述非弯折支撑板111与所述弯折支撑板112之间设置断缝11a，所述形变件17设置于所述断缝11a中。具体的，非弯折支撑板111与弯折支撑板112之间的连接处设置断缝11a，再通过将形变件17填充于该断缝11a之间。该形变件17可以为硅胶、 橡胶、弹簧等具有弹性的材料。可以理解的，由于形变件17具有弹性，弯折支撑板112的两侧在弯折过程中会分别朝着两个非弯折支撑板111滑动，而由于滑块13固定于弯折支撑板112的一侧上，而使得弯折支撑板112的弯折驱动滑块13滑动并挤压该形变件17，使得形变件17发生弹性变形，实现弯折支撑板112弯折后的长度补偿，防止可弯折终端100在弯折过程中柔性显示屏2被弯折支撑板112拉伸，提高了可弯折终端100的弯折可靠性。形变件17凸出于弯折支撑板112，也即，形变件17的厚度比弯折支撑片112厚，如此，形变件17可抵接于滑块13。该结构的形变件17能够弹性变形进行长度的补偿同时，亦能够为柔性显示屏2提供较佳的支撑。
请参照图3和图4，所述滑块13靠近所述形变件的上顶角抵接于所述形变件15上。本实施方式中，滑块13的主体部131的上顶角131a抵接于形变件15上，通过使得滑块13的上顶角抵接于形变件15上，而使得滑块13与形变件15之间的接触为点面接触，其会对形变件15提供更大的挤压力，而使得形变件15能够快速的发生弹性变形，从而实现可弯折终端100发生弯折时滑动13可更加快速地对弯折支撑件112进行长度补偿，进一步提高了可弯折终端100的弯折可靠性。
请再次参照图1和图2，所述壳体12还包括用于支撑弯折支撑板112的可弯折的连接件122，所述连接件122设置于所述第一框架121与所述第二框架123之间并连接所述第一框架121和所述第二框架123。本实施方式中，壳体12与所述柔性显示屏2的弯折区22正对的位置设有连接件122。连接件122包括多个依次铰接的多个铰链1221和固定柱1222。所述固定柱1222的一端收容于所述铰链1221，且所述固定柱1222的另一端固定于所述弯折支撑部上。具体的，多个铰链1221依次铰接形成一排，一排铰链1221的两个侧边分别位于第一框架121和第二框架123中一个铰链1221开设至少一个通孔，固定柱1222的一部分收容于铰链1221的一个通孔中，固定柱1222的另一端固定于弯折支撑板112远离柔性显示屏2的一侧上。其中，固定柱1222可以为刚性螺钉或销钉等。在其它实施方式中，连接件122还可以为包括多个依次啮合连接的齿轮和固定杆。多个依次内核连接的齿轮通过彼此之间的相互啮合而实现连接件122的折叠。固定杆与前述的固定柱1222的作用类似，在此不再赘述。
进一步的，请参照图6和图7，可弯折的连接件122可相对弯折支撑板112滑动。可以理解的，弯折支撑板112上设有滑移槽112a，当所述弯折支撑板112弯折时，所述固定柱可在所述滑移槽112a中滑动，并改变所述连接件122在所述弯折支撑板112弯折方向上的周长。本实施方式中，固定柱1222的另一部分收容于滑移槽112a中，且固定柱1222收容于与滑移槽112a中的部分的尺寸小于滑移槽112a，以实现连接件122在可弯折终端100弯折时，固定柱1222能够相对弯折支撑板112滑动，改变连接件122在弯折支撑板112弯折方向的周长。换言之，可弯折终端100在弯折的过程中，多个固定柱由于与弯折支撑板112为滑动连接，其能够与弯折支撑板112发生适应性的滑动，以保证多个铰链1221与弯折支撑板112的连接可靠性。当然，在其它实施方式中，弯折支撑板112上设有定位凸起，连接件122上对应设置有滑动槽，定位凸起滑动连接于滑动槽中，实现弯折支撑板112与连接件122的滑动连接。
本申请提供的可弯折终端100绕所述连接件122发生弯折时，所述弯折支撑板112随所述连接件122发生弯折，所述弯折支撑板112的弯折驱动所述滑块13朝所述非弯折区21的滑动驱动所述形变件15压缩并支撑与弯折状态下所述形变件15正对的柔性显示屏2，使其较为平整。如此，该滑块13在弯折终端绕连接件122发生弯折时朝非弯折区21的滑动可防止所述弯折支撑板112在随所述连接件122一起弯折过程对屏幕的拉伸长度进行补偿，防止可弯折终端100在弯折过程中柔性显示屏2被弯折支撑板112挤压拉伸，提高了可弯折终端100的弯折可靠性。
本申请第二实施方式提供了一种可弯折终端，该可弯折终端与实施方式一提供的可弯折终端100的结构大致相同，其不同之处主要在于：所述弯折支撑板与所述非弯折支撑板之间设置有间隙，即弯折支撑板与非弯折支撑板之间没有形变件连接，而是通过间隙隔开。当所述弯折支撑板弯折时，所述滑块朝所述柔性显示屏的非弯折区的滑动将使所述间隙的宽度发生变化。
本申请实施方式提供的可弯折终端通过所述弯折支撑板的弯折驱动所述滑块朝所述非弯折区滑动。如此，该滑块在可弯折终端发生弯折时朝非弯折区的滑动可保持柔性显示屏的长度保持不变，避免由于弯折过程中弯折支撑板拉扯柔性显示屏的弯折区而损伤柔性显示屏，从而提高可弯折支撑组件和可弯折 终端弯折的可靠性。
由于柔性显示屏发生弯折的区域与弯折支撑板是可相对滑动而没有直接固定，因而柔性显示屏在弯折时，在弯折区出现的弯折半径差异可以经由弯折支撑板朝非弯折支撑板进行滑动来吸收，从而避免或减少柔性显示屏被拉坏的情况。
本实施方式中所使用的柔性显示屏也可以采用其他类型的柔性显示屏代替，如柔性触摸屏，柔性发光屏等。
以上的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
