背景技术
随着柔性显示技术的发展，柔性屏越来越多的应用于终端设备。在终端设备中，通常将柔性屏和柔性屏支撑结构相结合，利用柔性屏支撑结构实现柔性屏的弯曲或者折叠。与传统屏幕相比，柔性屏具有的优势，例如，其体积轻薄，功耗低，而且由于柔性屏幕可弯曲、具有柔性等特点，其应用场景越来越广。但现有技术中柔性显示屏的支撑结构在柔性显示屏展开时，滑移机构直接作用于屏体，使得折叠的屏体展开，这就会导致屏体受力过大，影响屏体的使用寿命。

本申请提供一种支撑结构件及显示装置，旨在能够向柔性显示面板提供良好的支撑，提高柔性显示面板的使用寿命。
本申请第一方面的实施例提供了一种支撑结构件，用于柔性显示面板，支撑结构件包括：主体支撑件，包括用于承载部分柔性显示面板的承载部；滑移支撑件，沿第二方向可移动地连接于主体支撑件，滑移支撑件包括沿第一方向间隔分布的第一支撑部和第二支撑部，第一支撑部用于伸出主体支撑件并与承载部共同支撑柔性显示面板；推顶件，沿第二方向可移动地 连接于第二支撑部，推顶件包括止挡部，止挡部凸出于第二支撑部上用于支撑柔性显示面板的支撑面，以使止挡部能够止挡于柔性显示面板的一端并推动柔性显示面板移动。
本申请第二方面实施例还提供了一种显示装置，包括上述任一第一方面实施例的支撑结构件；柔性显示面板，具有相对的第一端和第二端，第一端连接于主体支撑件，第二端位于第二支撑部并被止挡部止挡，以使止挡部能够推动第二端沿远离主体支撑件的方向移动。
在本申请实施例的支撑结构件中，支撑结构件包括主体支撑件、滑移支撑件和推顶件，滑移支撑件沿第二方向可移动地连接于主体支撑件，当滑移支撑件沿第二方向相对主体支撑件移动时，滑移支撑件的第一支撑部能够与主体支撑件的承载部共同支撑柔性显示面板，以增大显示面积，实现大屏显示。此外，推顶件的止挡部设置于滑移支撑件的第二支撑部上，止挡部凸出于第二支撑部的支撑面，使得止挡部能够止挡于柔性显示面板的一端，通过止挡部能够推动柔性显示面板移动，使得部分折叠于第二侧的柔性显示面板移动至第一侧。在本申请实施例中，通过推动柔性显示面板的一端来实现大屏显示，止挡部作用于柔性显示面板的一端而非柔性显示面板的表面，能够减小柔性显示面板的受力，提高柔性显示面板的使用寿命。

在另一些可选的实施例中，驱动部件400包括第一驱动组410和第二驱动组420。第一驱动组410包括相互啮合的第一驱动轮411和第一齿条412，第一齿条412连接于止挡部310并沿第二方向延伸成型。第二驱动组420包括相互啮合的第二驱动轮421和第二齿条422，第二齿条422连接于第二支撑部220并沿第二方向延伸成型，第二驱动轮421和第一驱动轮411相互啮合。
第一驱动组410通过第一驱动轮411和第一齿条412驱动止挡部310移动，第二驱动组420通过第二驱动轮421和第二齿条422驱动滑移支撑件200移动。第一驱动轮411和第二驱动轮421相互啮合，使得第一驱动轮411和第二驱动轮421能够联动，当第一驱动轮411组通过第一齿条412推动止挡部310移动时，第二驱动轮421组也会通过第二齿条422推动滑移支撑件200移动。
可选的，第二驱动轮421包括同轴设置的第一齿轮421a和第二齿轮421b，第一齿轮421a和第一驱动轮411相互啮合，第二齿轮421b和第二齿条422相互啮合，且第一齿轮421a的半径为第二齿轮421b半径的整数倍。
在这些可选的实施例中，第二驱动轮421包括第一齿轮421a和第二齿 轮421b，第一齿轮421a和第一驱动轮411相互啮合，那么第一齿轮421a的转速和第一驱动轮411的转速相同，第一齿轮421a转动的距离与第一驱动轮411转动的距离相等。第二齿轮421b和第二齿条422相互啮合，第二齿轮421b用于驱动第二齿条422相互啮合。第一齿轮421a的半径为第二齿轮421b半径的整数倍，那么第一齿轮421a转动的距离是第二齿轮421b转动距离的整数倍，从而实现第二速率V2是第一速率V1的整数倍。
可选的，第二速率V2与第一速率V1的比值与第一齿轮半径与第二齿轮半径的比值相等。
如上，在一些可选的实施例中，当第二速率V2是第一速率V1的两倍，即V1:V2＝1:2时，第一齿轮421a的半径是第二齿轮421b半径的两倍，相同时间内第一齿轮421a转动的距离是第二齿轮421b转动距离的两倍，进而使得第二速率V2是第一速率V1的两倍。
在另一些可选的实施例中，当第二速率V2是第一速率V1的3倍时，第一齿轮421a的半径是第二齿轮421b半径的3倍，相同时间内第一齿轮421a转动的距离是第二齿轮421b转动距离的3倍，进而使得第二速率V2是第一速率V1的3倍。
本申请实施例的驱动部件400，结构简单，实施方便，能够实现显示装置的轻量化和简单化设置目的。
在本申请实施例提供的支撑结构件20中，驱动第一驱动组410和第二驱动组420的方式有多种，例如令第一驱动组410为主动驱动组。可以利用驱动结构驱动第一驱动组410中的第一驱动轮411进行转动，使得第一驱动轮411带动第一齿条412和第二驱动轮421转动，第二驱动轮421带动第二齿条422转动。或者利用驱动结构驱动第一驱动组410中的第一齿条412进行移动，第一齿条412带动第一驱动轮411转动，第一驱动轮411带动第二驱动轮421转动，第二驱动轮421带动第二齿条422移动。
在另一些实施例中，还可以令第二驱动组420为主动驱动组。可以利用驱动结构驱动第二驱动组420中的第二驱动轮421进行转动，使得第二驱动轮421带动第二齿条422和第一驱动轮411转动，第一驱动轮411带动第一齿条412转动。或者利用电机驱动第二驱动组420中的第二齿条422 进行移动，第二齿条422带动第二驱动轮421转动，第二驱动轮421带动第一驱动轮411转动，第一驱动轮411带动第一齿条412移动。
驱动结构的设置方式有多种，例如驱动结构为电机结构。在一些实施例中，驱动结构为卷绕驱动件430，以通过卷绕驱动件430驱动第一驱动轮411和/或第二驱动轮421转动，并推顶件300和滑移支撑件200移动。
例如以第一驱动组410为主动驱动组，卷绕驱动件430可以驱动第一驱动组410的第一驱动轮411进行转动，使得第一驱动轮411带动第二驱动轮421转动，进而第一齿条412和第二齿条422移动。
在一些可选的实施例中，还可以令第二驱动组420为主动驱动组，卷绕驱动件430可以驱动第二驱动组420的第二驱动轮421进行转动，使得第二驱动轮421带动第一驱动轮411转动，进而带动第二齿条422和第一齿条412移动。
如图12和图13所示，本申请实施例以第二驱动组420为主动驱动组为例进行说明。卷绕驱动件430设置于第二驱动轮421，卷绕驱动件430驱动第二驱动轮421转动，第二驱动轮421带动第一驱动轮411转动，第二驱动轮421还带动第二齿条422移动，第一驱动轮411带动第一齿条412移动。
当第二驱动轮421包括第一齿轮421a和第二齿轮421b时，卷绕驱动件430可以设置于第一齿轮421a和第二齿轮421b中的任一者。例如，卷绕驱动件430可以设置于体积较大的第一齿轮421a，第一齿轮421a能够为卷绕驱动件430提供足够的设置空间。
卷绕驱动件430例如为卷簧。第一齿轮421a例如包括让位槽，卷簧卷绕于第一齿轮421a内。在柔性显示面板10处于折叠状态、支撑结构件20处于收缩状态时，卷绕驱动件430处于收缩状态，卷绕驱动件430能够向第一齿轮421a施加卷绕驱动力，使得第一齿轮421a和第二齿轮421b同步转动，第二齿轮421b带动第二齿条422移动，第二齿条422带动滑移支撑件200沿远离主体支撑件100的方向移动，使得支撑结构件20由收缩状态向展开状态转变。同时，第一齿轮421a和第一驱动轮411啮合，第一齿轮421a带动第一驱动轮411转动，第一驱动轮411带动第一齿条412，第一 齿条412带动推顶件300推动柔性显示面板10由折叠状态向展平状态转变。
驱动部件400的数量可根据实际设计变化，驱动部件400可以设置一组，一组驱动部件400驱动推顶件300和滑移支撑件200移动。
在另一些实施例中，驱动部件400为两组以上，两组以上的驱动部件400沿第三方向间隔分布。通过两组以上的驱动部件400驱动推顶件300和滑移支撑件200在第三方向上的不同部位，一方面能够保证推顶件300和滑移支撑件200受力平衡，另一方面各驱动部件400使用较小的力即可推动推顶件300和滑移支撑件200移动。
例如，驱动部件400为两组，两组驱动部件400沿第三方向间隔分布，且两组驱动部件400相对于沿第二方向延伸的轴线对称分布，两组驱动部件400的第一齿条412相互连接设置，使得两组驱动部件400能够更加同步地驱动推顶件300和滑移支撑件200移动。
在一些可选的实施例中，支撑结构件20还包括锁止部件500，锁止部件500包括止动部510和按压部520。止动部51与第一驱动轮411和/或第二驱动轮421啮合。按压部520通过连接杆530与止动部510固定连接，连接杆530绕旋转轴540可转动设置，以使按压部520带动止动部510移动并与第一驱动轮411和/或第二驱动轮421相互啮合或相互分离。
在这些可选的实施例中，按压按压部520使得连接杆530能够转动，连接杆530带动止动部510与第一驱动轮411和/或第二驱动轮421啮合或分离，从而能够控制第一驱动轮411和/或第二驱动轮421的转动。
例如当第二驱动组420件为主动驱动组，第二驱动轮421包括第一齿轮421a和第二齿轮421b，第一齿轮421a内设置有卷簧，止动部510用于与第一齿轮421a相互啮合。且当支撑结构件20在收缩状态下，卷簧处于收缩状态，止挡部310与第一齿轮421a相互啮合阻止第一齿轮421a在卷簧的作用力下转动。按压按压部520，按压部520带动连接杆530绕旋转轴540转动，连接杆530带动止动部510与第一齿轮421a相互分离。第一齿轮421a不会受到止动部510的作用力，第一齿轮421a在卷簧的作用力下转动，带动第一齿轮421a组转动，使得驱动部件400能够驱动推顶件300和滑移支撑件200移动。当取消按压按压部520，按压部520复位，连接杆 530带动止动部510与第一齿轮421a相互啮合，第一齿轮421a受力不会转动，从而使得推顶件300和滑移支撑件200停止移动。
止动部510例如呈齿条状，止动部510上设置有间隔分布的两个以上锯齿，使得止动部510能够与第一驱动轮411和/或第二驱动轮421相互啮合。
连接杆530的形状设置方式有多种，连接杆530可以呈平直状或者弯折状，只要按压按压部520能够使得连接杆530带动止动部510与第一齿轮421a啮合或分离即可。
在一些可选的实施例中，锁止部件500还包括弹性部550，弹性部550一端连接于连接杆530靠近止动部510的一侧，弹性部550可往复变形设置，以使弹性部550能够带动止动部510与第一驱动轮411和/或第二驱动轮421啮合。可选的，弹性部550的一端连接连接杆530，弹性部550的另一端固定于滑移支撑件200。
在这些可选的实施例中，弹性部550连接于连接杆530，且位于旋转轴540朝向止动部510的一侧，弹性部550可往复变形设置，在弹性部550的弹性作用力下，连接杆530能够带动止动部510与第一驱动轮411和/或第二驱动轮421啮合。
例如，当第二驱动组420为主动驱动组，第二驱动轮421包括第一齿轮421a和第二齿轮421b，当取消按压按压部520，连接杆530在弹性部550的作用力下回弹，连接杆530带动止动部510重新与第一齿轮421a相互啮合。
可选的，按压部520凸出于主体支撑件100设置。便于用户由主体支撑件100的外部通过按压部520控制推顶件300和滑移支撑件200的移动。
参阅图3至图10，例如，主体支撑件100还包括连接于承载部110在支撑结构件20第三方向上两侧的侧板120，侧板120上设置有让位孔121，按压部520由让位孔121内伸出。可选的，让位孔121位于侧板120的远离滑移支撑件200的一端，且靠近主体支撑件100的端部，如此设置，符合人体工程学设计，方便用户操作按压部520。
可选的，主体支撑件100还包括与承载部110沿第一方向间隔设置的 背板，侧板120连接于承载部110和背板之间。滑移支撑件200的第二支撑部220设置于背板，并相对背板沿第二方向可移动设置。
参阅附图6、9、11，第一支撑部210包括沿第三方向间隔分布的两个以上第一支撑横梁211。承载部110包括沿第二方向依次分布的第一承载部110a和第二承载部110b，第二承载部110b位于第一承载部110a朝向过渡连接部230的一侧，第二承载部110b包括沿第三方向间隔分布的两个以上第二支撑横梁111，且第二支撑横梁111和第一支撑横梁211沿第三方向依次交替分布，使得第一支撑部210和承载部110能够在同一平面支撑柔性显示面板10，从而保证用于支撑柔性显示面板10的表面的平整性，减少对柔性显示面板10的摩擦，进一步提高柔性显示面板10的使用寿命。第二支撑梁111上设有固定弹性部550另一端的固定柱。
