配置成连接底座2和边框1的齿轮组件5，齿轮组件5包括配置成 与底座2转动连接的齿轮部件51、配置成与边框1连接的第一齿条52、配置成与滑动部件4连接的第二齿条53，第一齿条52和第二齿条53均与齿轮部件51啮合；
张紧组件6，张紧组件6与底座2连接，且与滑动部件4抵接，用以向滑动部件4施加与滑动部件4运动方向相反的作用力。
本公开实施例提供的柔性屏抽拉组件中，包括与显示装置10的边框1滑动连接的底座2、配置成与柔性屏3的移动端连接的滑动部件4、配置成连接滑动部件4与底座2的齿轮组件5以及与滑动部件4抵接以保证滑动部件4稳定运动的张紧组件6。将齿轮组件5中的第一齿条52与显示装置10的边框1连接，使第一齿条52形成齿轮组件5的固定端。由于底座2与齿轮部件51转动连接，底座2在外力作用下向远离第一齿条52的方向运动使，齿轮部件51绕自身轴线方向转动，第二齿条53在齿轮部件51的转动作用下，向远离第一齿条52的方向运动，使齿轮组件5拉伸，将柔性屏3展开，以增加显示装置10显示区的显示面积。同理，在底座2受外力作用朝向第一齿条52运动时，齿轮部件51转动，带动第二齿条53向靠近第一齿条52的方向运动，使齿轮组件5收缩，将柔性屏3收回，以减小显示装置10显示区的显示面积，从而实现了显示装置10显示区面积的调节。在齿轮组件5拉伸以及收缩的过程中，张紧组件6保持与滑动部件4抵接，以消除第二齿条53与齿轮部件51之间的虚位，从而保证滑动部件4运动的稳定性，有效避免了柔性屏3在拉伸以及收回的过程中产生不平整、晃动以及屏幕歪斜的问题，进而保证了柔性屏3在拉伸以及收回的过程中的稳定性，提高了显示装置10的使用体验。
图3为本公开实施例所述柔性屏抽拉组件抽拉过程的结构示意图，图4为本公开实施例所述柔性屏抽拉组件抽拉至极限位置的示意图，图5为本公开实施例所述张紧组件的爆炸图，图6为本公开实施例所述显示装置的爆炸图。如图3至图6所示，在一些实施例中，张紧组件6包括设置于底座2朝向滑动部件4一侧的滑轨组件和设置于滑动部件4上的滑动组件，滑轨组件包括弧形轨道61，滑动组件包括配置成与弧形轨道61的凸起面配合的滑块62和配置成与滑块62连接弹性 部件63，弹性部件63与滑动部件4抵接。
上述张紧组件6包括滑轨组件和滑动组件，滑轨组件设置于底座2，滑动组件设置于滑动部件4上，滑动组件与滑轨组件配合，以实现张紧组件6与滑动部件4的抵接。
具体地，由于滑块62与弧形轨道61的凸起面配合，在柔性屏3展开过程中，滑动部件4施加以滑块62沿滑动部件4运动方向的作用力，使滑块62与弧形轨道61抵接，弧形轨道61对滑块62产生与滑动部件4运动方向相反的作用力，该作用力通过滑块62传递至弹性部件63中，使弹性部件63与滑动部件4之间抵接，并对滑动部件4施加与滑动部件4运动方向相反的作用力，使配置成驱动滑动部件4运动的第二齿条53中的齿部与齿轮部件51中的齿部紧密啮合，从而实现了消除虚位的效果。
在滑块62到达弧形轨道61的顶部位置时，弧形轨道61与滑块62抵接产生的作用力消失。然后滑块62继续沿弧形轨道61滑动，由于弧形轨道61与滑块62之间产生的与滑动部件4滑动方向相反的作用力消失，滑块62可在不受外力作用下沿弧形轨道61滑动至弧形轨道61的端部，从而实现柔性屏3的自动展开。
在一些实施例中，滑动组件包括连接板64，连接板64设置在滑动部件4的一侧，配置成承载安装弹性部件63以及滑块62，连接板64上沿平行于滑动部件4的延伸方向设置有开槽65，滑块62与开槽65配合。
上述滑动组件中，通过在连接板64上设置开槽65，限制了滑块62在连接板64上的运动方向，在滑块62沿弧形轨道61运动过程中，滑块62在连接板64上沿开槽65的方向运动，使与滑块62连接的弹性部件63进一步被压缩，当滑块62运动至弧形轨道61的顶部后，滑块62可在弹性部件63产生的回复力的作用下沿开槽65的方向以及滑轨的方向运动至弧形轨道61的底部，从而实现柔性屏3的自动展开。
具体地，弹性部件63包括扭簧，扭簧的一端与滑块62连接，扭簧的另一端与连接板64连接，配置成使扭簧的中部与滑动部件4抵接。
通过设置扭簧，在扭簧的一端设置滑块62，另一端与连接板64 连接，在滑块62运动过程中，扭簧被压缩，使扭簧的主体部分与滑动部件4保持抵接，从而保证滑动部件4运动的稳定性。
在一些实施例中，弧形轨道61背离凸起面的一侧形成平面，连接板64朝向所述底座2的一侧设置有限位挡块67，限位挡块67与平面配合，在滑动部件4运动过程中，限位挡块67与上述平面抵接，并沿平面运动，以保证滑动部件4沿直线方向稳定运动，避免滑块62受弧形导轨凸起面的作用力时，滑动部件4的运动方向发生偏移。
具体地，上述限位挡块67为尼龙圈。
在一些实施例中，滑轨组件还包括限位部66，弧形轨道61的两端均设置有限位部66。
上述弧形轨道61的两端均设置限位部66，以实现对滑块62初始位置以及终点位置的限位作用，有效防止滑块62滑轨组件脱离。
图7为本公开实施例所述滑动部件与底座滑动配合结构的示意图。如图7所示，在一些实施例中，底座2上设置有第一滑动配合部7，滑动部件4上设置有配置成与第一滑动配合部7滑动配合的第二滑动配合部8。
通过在底座2上设置第一滑动配合部7，在滑动部件4上设置第二滑动配合，以实现滑动部件4与底座2之间的滑动连接，从而实现滑动部件4与底座2之间相对运动方向的限制，保证底座2与滑动部件4的运动方向一致，从而保证柔性屏3展开或收回时，运动方向的稳定性。
在一些实施例中，第一滑动配合部7和第二滑动配合部8中，至少一者的配合面包括自润滑材料层。
通过设置自润滑材料层，可有效减小滑动部件4与底座2之间的滑动摩擦力，保证滑动部件4与底座2之间滑动顺畅，并减小柔性屏3展开或收回过程中底座2与滑动部件4之间摩擦产生的声音。
具体地，自润滑材料层可以包括尼龙。
在一些实施例中，还包括压板9，压板9设置在齿轮组件5背离底座2的一侧，与齿轮部件51转动连接。
通过设置压板9，可对齿轮组件5起到保护作用。
图8为本公开实施例所述显示装置展开前的示意图，图9为本公开实施例所述显示装置展开后的示意图。如图1至图9所示，在一个实施例中，提供了一种显示装置10，包括上述的柔性屏抽拉组件。
本公开实施例提供的显示装置10中，包括边框1以及与边框1滑动连接的底座2，通过底座2相对边框1产生相对滑动，带动齿轮组件5、配置成与柔性屏3的移动端连接的滑动部件4移动，从而实现了柔性屏3显示面积大小的调节。并且，通过设置张紧组件6，提高了柔性屏3运动的稳定性，从而提高了显示装置10使用的稳定性，以及使用体验。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本公开的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本公开构思的前提下，还可以做出若干变形和改进，这些都属于本公开的保护范围。因此，本公开专利的保护范围应以所附权利要求为准。
