具体而言，该电子设备10可以包括柔性屏20和屏幕卷曲装置(图未示)，柔性屏20与屏幕卷曲装置连接，柔性屏20可以是OLED柔性显示屏或者AMOLED(Active-matrix organic light-emitting diode，有源矩阵有机发光二极体或主动矩阵有机发光二极体)柔性显示屏等。屏幕卷曲装置为本申请提供的屏幕卷曲装置。
在柔性屏20未展开时，部分柔性屏20暴露在电子设备10的正面，作为电子设备10的显示区域，而另一部分柔性屏20通过屏幕卷曲装置卷曲在电子设备10内部；在在柔性屏20展开后，卷曲在电子设备10内部柔性屏20被屏幕 卷曲装置推出，电子设备10的显示区域增大。通过屏幕卷曲装置，能够实现电子设备10的多种形态的切换。

请参阅图3和图4，图3是本申请屏幕卷曲装置一实施例的结构示意图，图4是图3中A-A’截面的结构示意图。屏幕卷曲装置30包括固定件100、滑动件200以及阻隔件300。
具体地，滑动件200与固定件100相邻设置，滑动件200可以相对于固定件100滑动。例如在本实施例中，固定件100和滑动件200平行设置，滑动件200能够与固定件发生相对运动，且滑动件200与固定件100始终保持平行的状态。
可选地，可以采用电机驱动的方式，电机驱动滑动件200运动，使滑动件200能够与固定件发生相对滑动。
为了更好的理解本实施例中屏幕卷曲装置的工作方式，请一并参阅图3～5，图5是图4实施例中屏幕卷曲装置与柔性屏连接的结构示意图。
在本实施例中，柔性屏20一部分固定在固定件100远离滑动件200的一侧，另一部分从固定件100远离滑动件200的一侧起，延伸至滑动件200远离固定件100的一侧。在作为电子设备的显示装置时，柔性屏20位于固定件100一侧的部分作为显示区域，位于滑动件200一侧的柔性屏20位于电子设备内部被隐藏。在电子设备需要展开柔性屏20时，滑动件200相对于固定件100产生滑动，位于电子设备内部的部分柔性屏20被滑动件推出，与原本固定在固定件100上的柔性屏20组成新的显示区域，显示区域面积增大。在电子设备需要回收柔性 屏20时，会相对于固定件100往原始方向滑动，把推出的部分柔性屏20回拉，减小电子设备的显示区域的面积。
可选地，位于固定件100一侧的柔性屏20可以通过粘接的方式与固定件100固定，位于滑动件200一侧的柔性屏20可以通过挂绳连接或者粘接的方式与滑动件200连接。
在相关技术中，滑动件200与固定件100之间都会设置一定的距离，防止在滑动的过程中滑动件200与固定件100接触，产生滑动摩擦。但为了减小电子设备厚度，滑动件200与固定件100不能设计得过远。因此，在滑动件200与固定件100产生滑动时，滑动件200滑动的方向有可能会产生偏移，往固定件100所在的方向滑动，如此难免会与固定件100接触产生滑动摩擦。滑动件200与固定件100产生滑动摩擦不仅有可能会使滑动件200卡死、难以滑动，柔性屏20无法展开或者回收。加上滑动件200与固定件100都是采用铝合金等金属材料制成，在滑动时甚至有可能会磨损滑动件200或者固定件100，造成电子设备的损坏。
为了解决上述问题，在本实施例中，滑动件200和固定件100之间设有阻隔件300。阻隔件300用于间隔固定件100和滑动件200，防止固定件100与滑动件200接触。在滑动件200与固定件100产生滑动运动时，由于阻隔件300的存在，能够防止滑动件200与固定件100直接接触，保护滑动件200与固定件100不受滑动摩擦的影响。
在本实施例中，阻隔件300与滑动件200保持在0.5mm左右的距离，阻隔件300设于滑动件200靠近固定件100的一侧，而固定件100与阻隔件300保持在0.1～0.2mm左右的距离。在理想状态下，阻隔件300不会与固定件100接触，而若滑动件200在滑动时偏移，往固定件100的方向滑动，此时阻隔件300会与固定件100接触，将滑动件200与固定件100间隔开来，防止滑动件200与固定件100之间产生滑动摩擦。
在其他的实施例中，阻隔件300也可以设于固定件100靠近滑动件200一侧，阻隔件300与滑动件200保持一定的距离，同样也能达到相同的效果，此处不作限定。
进一步地，屏幕卷曲装置30还可以包括装饰件400，装饰件400用于装饰、封装，可以设于滑动件200远离固定件100的一侧，与滑动件200连接。
一并参阅图5和图6，图6是图3实施例中屏幕卷曲装饰的爆炸结构示意图，图7是图6实施例中的区域放大图。在本实施例中，阻隔件300包括滚轮301，滚轮301用于将阻隔件300与固定件100的滑动摩擦力转化成滚动摩擦力。
滚轮301设于滑动件200靠近固定件100的一侧，并且滚轮301与固定件100的距离在0.1～0.2mm左右。在滑动件200相对于固定件100发生滑动时，理想状态下阻隔件300不与固定件100接触。但是实际使用情况下滑动件200会往固定件100的方向偏移，导致阻隔件300与固定件100接触，此时滚轮301能够在固定件100上滚动，产生滚动接触。由于滚动摩擦的摩擦力小于滑动摩擦，因此阻隔件300采用滚轮301的方式能够有效减小阻隔件300与固定件100接触后的摩擦力，进一步减小滑动件200与固定件100之间的滑动阻力。
具体而言，在上述实施例中，阻隔件300还可以进一步包括转轴302以及两个转轴支架303。滑动件200内至少设有两个凹槽201，转轴支架303固定安装在滑动件200的凹槽201内。
可选地，转轴支架303可以通过粘接、螺丝连接、卡扣等方式固定在凹槽201内。例如在采用卡扣的方式时，凹槽201内设有卡槽，而转轴支架303设有对应的卡扣，在转轴支架303安装在凹槽201时，卡扣与卡槽扣合。
转轴支架303设有轴孔3031，分别位于两个凹槽201内的两个转轴支架303的轴孔3031相对设置，转轴302的两队插置在轴孔3031内，并与两个转轴支架303保持固定。
滚轮301为管道状，滚轮301套设在转轴302上，在滚轮301与固定件100滚动接触时，滚轮301能够绕着转轴302转动。为了确保滚轮301能够正常滚动，滚轮301在套设在转轴302时，保持滚轮301与转轴302的距离在0.01～0.03mm内，例如0.01mm、0.015mm、0.02mm、0.025mm、0.03mm。在此距离下，滚轮301既能够绕着转轴302转动，又不会在转轴302上松动。
可选地，转轴支架303可以由塑胶材料制成，例如可以使用PA+50％GF材料(尼龙+50％玻璃纤维)。塑胶材料具有良好的加工性能，成型性良好，可以按需求制备出预设形状，使得塑胶材料制备得到的转轴支架303可以较好地安装在凹槽201中。
可选地，转轴302可以由金属材料制成。例如经过热处理后的不锈钢420，其具有较强的耐磨性、腐蚀性和硬度。
可选地，滚轮301可以由树脂材料制成，可选为POM材料。POM材料具有较高的弹性模量，硬度堪比金属，但是重量轻，不会过度增大整体重量。
在示例性的实施例中，滚轮301的数量为两个，每个滚轮301都有对应用于安装滚轮301的转轴支架303、转轴302。两个滚轮301分别设于滑动件200靠近固定件100一侧的不同位置，例如可以是滑动件200的两个角落、滑动件200的两边。设置两个滚轮301可以加强阻隔件300的间隔效果，在其他的实施例中，阻隔件300的数量可以是两个以上，每个阻隔件300设在滑动件200靠近固定件100一侧的不同位置。
因此，在上述实施例中，滑动件200与固定件100之间采用了阻隔件300间隔的方式，防止了滑动件200与固定件100直接接触的情况出现。同时，阻隔件300包括滚轮301，降低了在阻隔件300与固定件100接触时产生的摩擦力大小，使得滑动件200的滑动更顺畅，屏幕在推拉时不会产生顿挫感，减小了固定件100和滑动件200被划伤的风险。
请参阅图8，图8是本申请屏幕卷曲装置另一实施例的结构示意图。在其他的一些实施例中，为了降低制作阻隔件300的成本，屏幕卷曲装置30包括固定件100、滑动件200以及阻隔件300，阻隔件300可以包括泡棉层310，固定件100与滑动件200的结构和功能和上述实施例类似，此处不再赘述。
具体地，泡棉层310为经过压缩后的可压缩泡棉，可压缩泡棉在压缩后铺设在滑动件200靠近固定件100的一侧。泡棉层310可以采用粘接的方式与滑动件200连接，泡棉层310用于间隔固定件100和滑动件200。阻隔件300与滑动件200保持在0.5mm左右的距离，泡棉层310的厚度在0.2mm～0.4mm左右。
泡棉层310具有一定的弹性，重量轻，能够起到一定的间隔效果。同时泡棉层310结构简单，易于制备。
可选地，泡棉层310也可以铺设于固定件100靠近滑动件200的一侧，此处不作限定。
请参阅图9，图9是本申请屏幕卷曲装置又一实施例的结构示意图。在此实施例中，屏幕卷曲装置30包括固定件100、滑动件200以及阻隔件300，阻隔件300可以包括树脂块320，固定件100与滑动件200的结构和功能和上述实施例类似，此处不再赘述。
树脂块320固定在滑动件200靠近固定件100一侧，在滑动件200往固定 件100一侧偏移时，同样也起到间隔固定件100和滑动件200的作用。
树脂块320可选为POM材料，具有很强的耐磨性。树脂块320的数量可以是多个，不同的树脂块320设于滑动件200靠近固定件100一侧的不同位移，共同在滑动件200往固定件100方向滑动时起到支撑、间隔的作用。
在更多的实施例中，阻隔件300还可以采用无纺布、水凝胶、泡沫等材料制成，凡是在固定件100和滑动件200设置间隔物以达到阻隔效果的技术方案，均在本申请的保护范围内。
综上，本申请提供了屏幕卷曲装置和电子设备的实施例，屏幕卷曲装置能够有效保护内部结构，防止滑动件以及固定件直接接触产生的滑动磨损，延长电子设备的使用寿命。阻隔件还可以使用滚轮结构，进一步减小阻隔件与固定件之间的摩擦力，使得滑动件滑动地更顺畅，改善目前卷轴屏电子设备在展开或者回收时出现的顿挫感的情况。
