实施本发明的方式
为使本申请的目的、技术手段和优点更加清楚明白，以下结合附图对本申请作进一步详细说明。
图1a和图1b所示分别为本申请一实施例提供的可折叠支撑装置展开状态和折叠状态的结构示意图。如图1a和图1b所示，本申请实施例提供的一种可折叠支撑装置包括：设置于柔性显示屏体1的非显示区一侧的驱动组件2和支撑组件4，驱动组件2可设置于柔性显示屏体1的弯折区并用以实现柔性显示屏体1的折叠或展开，支撑组件4用以支撑并固定柔性显示屏体1的非弯折区，该支撑装置还包括连接驱动组件2和支撑组件4并且相互啮合的转动齿轮21和齿条3，齿条3和转动齿轮21中的一个与驱动组件2固定连接、另一个与支撑组件4固定连接，转动齿轮21沿着齿条3啮合转动并相对位移以实现折叠或展开柔性显示屏体1。
下面以转动齿轮21与驱动组件2固定连接、齿条3与支撑组件4固定连接为例具体的说明本实施例实现的过程。如图1c所示，当柔性显示屏体1折叠时，转动齿轮21逆时针或顺时针旋转，并通过转动齿轮21与齿条3的啮合结构使得齿条3在所处的平面相对转动齿轮21(即相对驱动组件2)向右或向左移动，从而 带动与齿条3固定连接的支撑组件4向右或向左移动，实现驱动组件2与支撑组件4的相对位移。并且，在可折叠式柔性显示装置从展开状态到折叠状态的过程中(即柔性显示屏体的弯折角度越大)，支撑组件4距离驱动组件2越远。当柔性显示屏体1折叠时，齿条3与转动齿轮21啮合运动并带动支撑组件4向远离驱动组件2的方向运动，为柔性显示屏体1的弯折区产生足够的收纳空间，防止直接折叠所导致的柔性显示屏体1的弯折区弯折挤压幅度过大，并且通过产生收纳空间，减小了折叠的角度，进一步减缓弯折挤压幅度，有效防止柔性显示屏体1因折叠而导致显示失效。柔性显示屏体1展开过程为其折叠过程的逆过程，即当柔性显示屏体1展开时，转动齿轮21转动以驱动齿条3运动并带动与齿条3连接的支撑组件4向靠近驱动组件2的方向运动以实现柔性显示屏体1的展开，此处不再赘述。
在另一实施例中，可以是转动齿轮21与支撑组件4固定连接、齿条3与驱动组件2固定连接。当柔性显示屏体1折叠时，转动齿轮21逆时针或顺时针旋转，并在齿条3所处的平面相对齿条3(即相对驱动组件2)向左或向右移动，从而带动与转动齿轮21固定连接的支撑组件4向左或向右移动，实现驱动组件2与支撑组件4的相对位移以折叠柔性显示屏体1。柔性显示屏体1展开过程为其折叠过程的逆过程，即当柔性显示屏体1展开时，转动齿轮21沿齿条3运动并带动与转动齿轮21连接的支撑组件4向靠近驱动组件2的方向运动以实现展开，此处不再赘述。
应当理解，本申请实施例中可以选择转动齿轮21与驱动组件2固定连接、齿条3与支撑组件4固定连接，也可以选择转动齿轮21与支撑组件4固定连接、齿条3与驱动组件2固定连接，本申请实施例对于转动齿轮与齿条的设置位置不做限定。但是出于在折叠或展开时同时实现支撑组件4与驱动组件2的相对运动，本实施例优选地方案为转动齿轮21与驱动组件2固定连接、齿条3与支撑组件4固定连接，柔性显示屏体1折叠或展开时，驱动组件2可直接带动转动齿轮21转动以同时实现支撑组件4与驱动组件2的相对位移。
在一实施例中，该支撑装置还可以进一步包括弯折驱动机构，构造为驱动柔性显示屏体1折叠或展开。在进一步的实施例中，弯折驱动机构可以包括电机等能够提供持续驱动力的驱动机构，电机的动力输出轴连接转动齿轮21，由电机提供动力、动力输出轴带动转动齿轮21沿着齿条3转动并相对位移，从而带动支撑组件4与驱动组件2的相对运动，以实现柔性显示屏体1的折叠或展开。通过设置弯折驱动机构，可以提高柔性显示屏体折叠或展开的效率，同时也可以省去人力折叠或展开所需要的工作量。
图2a和图2b所示分别为本申请一实施例提供的可折叠支撑装置展开状态和折叠状态的结构示意图。如图2a和图2b所示，柔性显示屏体1可以包括第一区 域11、第二区域12以及位于第一区域11和第二区域12之间的弯折区13；当柔性显示屏体1在弯折过程中时，转动齿轮21沿着齿条3转动并相对位移，继而带动柔性显示屏体1的第一区域11或第二区域12折叠运动的同时支撑组件4也向远离驱动组件2的方向移动。通过设置转动齿轮21及齿条3，当柔性显示屏体1折叠时，转动齿轮21沿齿条3运动并相对位移以带动支撑组件4向远离驱动组件2的方向运动，为柔性显示屏体1折叠产生足够的收纳空间，有效防止柔性显示屏体1因折叠而导致显示失效。
应当理解，本实施例中柔性显示屏体1可以是一整体屏体结构，为了表述方便清楚，将柔性显示屏体1划分为第一区域11、第二区域12以及弯折区域13三个部分；柔性显示屏体1也可以是由相互分离的第一区域11、第二区域12以及弯折区域13三部分组成，本实施例对于柔性显示屏体的具体结构不做限定。
在一实施例中，该支撑组件4可以包括至少一个壳体结构；至少一个壳体结构用于支撑并固定柔性显示屏体1的非弯折区。优选地，本实施例中壳体结构可以包括第一壳体41和第二壳体42，第一壳体41和第二壳体42分别支撑并固定上述实施例中的柔性显示屏体1的第一区域11和第二区域12。当柔性显示屏体1折叠时，转动齿轮21沿着齿条3转动并相对位移以带动壳体结构向远离驱动组件2的方向移动，为柔性显示屏体1的弯折区13提供充足的收纳空间，以防止柔性显示屏体1因折叠而导致显示失效。
在一实施例中，该支撑装置可包括多个齿条3以及与多个齿条3分别啮合的多个转动齿轮21。当柔性显示屏体1折叠时，转动齿轮21沿着齿条3转动并相对位移以带动壳体结构向远离驱动组件2的方向移动，为柔性显示屏体1的弯折区域13提供充足的收纳空间，以防止柔性显示屏体1因折叠而导致显示失效。
应当理解，本申请实施例中的齿条及转动齿轮的数量可以根据实际应用场景而定，只要齿条及转动齿轮的数量能够实现柔性显示屏体的折叠操作即可，本申请实施例对于齿条及转动齿轮的数量不做限定。
应当理解，本申请实施例中的与每个壳体结构固定连接的齿条或转动齿轮的数量可以根据实际应用场景而定，可以是每个壳体结构只与一个齿条或转动齿轮固定连接，也可以是每个壳体结构与多个齿条或转动齿轮固定连接，只要与每个壳体结构固定连接的齿条或转动齿轮的数量能够实现柔性显示屏体的折叠操作即可，本申请实施例对于与每个壳体结构固定连接的齿条或转动齿轮的数量不做限定。
在一实施例中，本实施例中可以只在第一壳体41一侧设置齿条3，在柔性显示屏体1折叠或展开时，通过转动齿轮21沿着齿条3转动，从而带动第一壳体41向远离或靠近驱动组件2的方向运动；也可以只在第二壳体42一侧设置齿条3，在柔性显示屏体1折叠或展开时，通过转动齿轮21沿着齿条3转动，从而带动第 二壳体42向远离或靠近驱动组件2的方向运动；或者还可以在第一壳体41和第二壳体42一侧都设置齿条3，在柔性显示屏体1折叠或展开时，通过转动齿轮21沿着齿条3转动，从而带动第一壳体41和第二壳体42向相互远离或靠近的方向运动。
