Description

柔性屏支撑装置及显示终端 技术领域
本申请涉及显示技术领域，例如涉及一种柔性屏支撑装置及显示终端。
背景技术
手机、平板电脑等显示类智能终端产品，为了给用户带来更好的感官享受，大屏幕化已经成为必然的发展趋势。然而，屏幕越大也会使智能终端的体积变大，不便于随身携带。面对这个两难问题，柔性屏显示类智能终端产品应运而生。柔性屏可以自由弯曲，它使显示类智能终端产品能够摆脱固有的刚性结构，实现更加多样化的结构形式，如弯曲造型，屏幕卷曲收纳等，从而减小显示类智能终端产品的体积。柔性屏智能终端能够兼具大屏的感官享受以及小屏的方便携带，已经成为智能终端产品的重要发展方向。
使用柔性屏的移动终端，主要有两个方向：
一个方向是使用柔性屏的3维(3-Dimension，3D)曲面手机，3D曲面的柔性屏以曲面形态制作好后，在使用过程中形态不会进行动态变化。这种方案的优点是：生产难度相对较小，工艺技术也比较成熟，已经实现了大规模量产；但缺点是：只对柔性屏做静态曲面应用，并没有将柔性屏的优势充分发挥出来。
另一个方向是将柔性屏应用于折叠机上，通过翻折方式实现终端屏幕尺寸的大小转换。但这种方式并没有缩小终端的体积，在减小屏幕的同时厚度会随之增加，仍然存在不便于携带的问题；同时，双屏折叠机已经实现了折叠机的基本功能，因此将柔性屏应用于折叠机并不能给用户带来全新的体验。
相关技术中将柔性屏应用在3D曲面屏和柔性折叠屏两个方面，虽然能够改变平面显示的局限，但这两种方式并没有缩小终端的体积及充分发挥柔性屏的优势。
发明内容
申请提供一种柔性屏支撑装置及显示终端，能够实现可扩展式柔性屏的自如卷曲和伸展，使用户既能享受大屏的感官效果，又能方便携带，提升用户体验。

卷绕机构2设置有两组，两组卷绕机构2对称设于壳体1开口的两侧。支撑结构3也对称设置有两组，两组支撑结构3一一对应地与两组卷绕机构2连接。本实施例中，支撑结构3由硬质材质制作，两组支撑结构3相对的表面设有啮合齿31，在非啮合状态下，支撑结构3能够向啮合齿31所在的一侧弯曲，呈可弯曲的板状结构；两组支撑结构3通过彼此的啮合齿31相互啮合后，能呈现出硬质的直板形状，从而对柔性屏100形成硬性支撑，避免柔性屏100在使用过程中发生弯曲。支撑结构3的第一端与卷绕机构2固定连接，并能随卷绕机构2的旋转而释放或卷曲，两组支撑结构3的第二端通过啮合齿31相互啮合并伸出壳体1的开口。上述设置使得，当需要使用柔性屏100时，可通过抽拉支撑结构3的第二端，将支撑结构3和柔性屏100拉出，由于相互啮合后的支撑结构3呈现为展平状态，能为柔性屏100提供硬性支撑平面，便于用户观看和使用屏幕；当需要收纳柔性屏100时，可通过卷绕机构2将支撑结构3和柔性屏100弯曲卷绕，能使柔性屏100卷曲收纳于壳体1内，节省空间，方便携 带。
为便于将柔性屏100和支撑结构3抽出壳体1，本实施例的柔性屏支撑装置还包括抽拉部4，抽拉部4固定于支撑结构3的第二端，抽拉部4可选为抽拉把手。如图6所示，本实施例中还设置有复位机构23，复位机构23设置为使卷绕机构2旋转收卷支撑结构3，以实现对柔性屏100的卷曲收纳。
可选地，支撑结构3上还设有磁性件，两组支撑结构3的磁性件具有相异的磁性，以使两组支撑结构3啮合后，能通过磁性作用相吸合。本实施例中，磁性件可以为永磁体，也可以为电磁铁，只要能实现两组支撑结构3的磁性吸合即可。参考图2，当需要使用扩展屏幕时，沿图2中水平粗箭头方向拉动抽拉部4，支撑结构3与其上的柔性屏100一起从壳体1内拉出，卷绕机构2随之沿着图2中弧形粗箭头方向转动，释放支撑结构3与其上的柔性屏100；由于两组支撑结构3均设有啮合齿31，二者能够通过啮合齿31相互啮合，同时由于两组支撑结构3带有相异的磁性，二者能够通过磁性作用交错吸合，从而更好地避免了两组支撑结构3发生分离，能为其上的柔性屏100提供硬性支撑平板，提高了装置的使用可靠性。
图4示出本申请实施例提供的一种梯形啮合齿31的示意图。图5示出本申请实施例提供的一种三角形啮合齿31的示意图。参考图4-图5，本实施例的啮合齿31可以为三角形齿，也可以为梯形齿，或者渐开线形齿、圆弧形齿等，只要保证两组支撑结构3上的啮合齿31能够相互匹配啮合，实现支撑结构3对柔性屏100的硬性支撑作用即可。同时，啮合齿31应尽可能设置为较为细小的结构，以增大支撑结构3的弯曲卷绕能力。本实施例可用于双面柔性屏产品，此时两组支撑结构3的非啮合面均设置有柔性屏100，以实现可扩展双面屏设计；也可以用于单面柔性屏产品，此时仅在一组支撑结构3的非啮合面设置有柔性屏100，以作为单面柔性屏的支撑结构，而且在该情况下，另一组支撑结构3的非啮合面也可以设置可弯曲柔性材质薄板，例如塑胶材质或金属材质的薄板等。
图6示出本申请实施例提供的另一种柔性屏支撑装置的结构示意图。参考图6，本申请实施例中卷绕机构2包括转动环22，支撑结构3的第一端与转动环22固定连接，例如可通过胶粘、紧固件或卡扣结构固定于转动环22上。复位机构23的一端与转动环22固定连接，复位机构23能随转动环22的转动而上紧或放松，设置为使转动环22旋转收卷支撑结构3。本实施例在抽出支撑结构3时，转动环22随之发生转动，使复位机构23上紧；而需要收纳支撑结构3和柔性屏100时，放开支撑结构3和柔性屏100，在复位机构23恢复力的作用下，转动环22带动支撑结构3及柔性屏100转动复位，使支撑结构3和柔性屏100缠绕在转动环22上。可选地，该复位机构23为发条或卷簧，其结构简单， 安装方便，工作可靠。
图7示出本申请实施例提供的一种卷绕机构的第一状态示意图，图7中粗箭头方向表示转动环22的旋转方向。图8示出本申请实施例提供的一种卷绕机构的第二状态示意图，图8中粗箭头方向表示转动环22的旋转方向。图9示出本申请实施例提供的一种卷绕机构的第三状态示意图。参考图7-图9，本实施例还包括单向锁止机构，以实现柔性屏100扩展拉伸的随时停止。单向锁止机构包括固定棘轮21、棘爪25和弹性件26，固定棘轮21固定于壳体1内，转动环22套设于固定棘轮21上，转动环22能相对于固定棘轮21转动。复位机构23的一端与固定棘轮21的轴心固定连接。固定棘轮21的周面均匀设置有多个齿槽24；棘爪25的一端与转动环22通过弹性件26可伸缩连接，棘爪25的另一端能沿齿槽24滑动或锁止于齿槽24中。上述设置使得棘爪25能够随转动环22一起转动，使支撑结构3和柔性屏100能够顺利展开或卷曲，同时通过棘爪25与齿槽24的限制作用，阻止转动环22自动复位，使用户能够自如拉出需要长度的柔性屏100。可选地，上述弹性件26为弹簧，转动环22内设置有凹槽，弹簧的一端与棘爪25固定连接，另一端与凹槽的底部抵接，以简化结构，方便安装。可选地，齿槽24的横截面包括弯曲斜边和止挡直边，如图7所示，棘爪25能沿弯曲斜边沿顺时针方向滑动，而止挡直边能够阻止棘爪25沿逆时针方向转动。本实施例使得在屏幕拉伸扩展过程中，可按照用户的需求实现显示屏大小的任意调节，在任何屏幕大小状态下，支撑结构3都能对其上的柔性屏100提供可靠的硬性支撑保护。
该柔性屏支撑装置还包括解锁机构，解锁机构可以通过手动方式实现或者通过***自动控制。当解锁机构采用手动方式时，可在壳体1上设置机械推钮，机械推钮与弹性件26或棘爪25连接，通过推动机械推钮能使弹性件26收缩，以带动棘爪25脱离齿槽24，从而实现对棘爪25的解锁，此时，旋转环22在发条的恢复力作用下能够带动支撑结构3及柔性屏100复位，从而使柔性屏100弯曲收纳在壳体1内。当解锁机构采用自动方式时，可设置驱动组件，驱动组件与弹性件26或棘爪25连接，驱动组件能使弹性件26收缩，以带动棘爪25脱离齿槽24；同时驱动组件与控制***信号连接，用户可通过软件界面或按键等方式控制驱动组件动作，以带动棘爪25脱离齿槽24，从而实现对棘爪25的解锁。采用自动控制的方式进一步提高了产品的智能性，提升了用户体验。本实施例中，驱动组件可以为电机及传动机构、电磁铁机构、气缸机构、液压缸机构、电动推杆机构等。
本申请实施例的工作原理如下：
当需要将柔性屏100拉伸扩展时，旋转环22沿着图7粗箭头所示方向顺时 针转动，带动棘爪25沿着齿槽24的弯曲斜边顺时针滑动，弯曲斜边将棘爪25逐渐顶起，压缩弹性件26，棘爪25一直滑动到图8所示齿槽24的弯曲斜边的顶部位置；同时随着旋转环22的转动，复位机构23逐渐上紧，产生逆时针恢复的反弹力。
旋转环22继续顺时针转动，带动棘爪25从图8位置滑动到图9所示齿槽24的止挡直边位置，如果此时柔性屏100停止拉伸扩展，旋转环22停止顺时针转动，由于复位机构23被上紧，有逆时针恢复的反弹力，所以旋转环22此时有逆时针恢复的趋势，但由于棘爪25卡入齿槽24中，此时旋转环22不会转动，所以柔性屏100的拉伸扩展可以随时停止。
当需要将柔性屏100卷曲收纳时，通过操作壳体1上的机械推钮或通过软件***控制驱动组件动作，使弹性件26收缩，带动棘爪25离开齿槽24，则旋转环22在复位机构23逆时针恢复的反弹力带动下，会逆时针转动，将其上的支撑结构3和柔性屏100卷曲收纳。
本申请实施例提供的柔性屏支撑装置，通过两组支撑结构3相互啮合，使柔性屏100展平时，支撑结构3能为柔性屏100提供硬性支撑平面；在两组支撑结构3分离后，通过卷绕机构2带动支撑结构3卷曲，能使柔性屏100卷曲收纳在壳体1内。
本申请实施例还提供一种显示终端，包括柔性屏100，还包括上述的柔性屏支撑装置，其中，柔性屏100设置于柔性屏支撑装置上。当显示终端为单面柔性屏时，柔性屏100的数量为一个，此时两组支撑结构3中的一组与柔性屏100固定贴合，例如可通过粘接等方式将柔性屏100固定于支撑结构3的非啮合面；并且此种情况下，另一组支撑结构3也可以设置可弯曲柔性材质的薄板。当显示终端为双面柔性屏时，柔性屏100的数量为两个，两组支撑结构3一一对应地与两个柔性屏100固定贴合，同样可通过粘接等方式将柔性屏100固定于支撑结构3的非啮合面。
本申请实施例利用柔性屏100的可弯曲收纳特性，并辅助以巧妙的支撑结构3和卷绕机构2，实现了柔性屏100的灵活扩展与回收，使显示终端的屏幕可以自如地扩大和缩小，且厚度并不会随之增加，小屏模式时尺寸小，便于随身携带；而需要观看视频或玩游戏时，可以轻松转换为大屏模式，体验更好的感官享受，从而兼具大屏和小屏的双重优点，带给用户全新的使用体验。
