随着柔性屏的发展，折叠式显示屏的电子设备受到越来越多的关注。一种折叠式显示屏的电子设备中，在柔性屏底部固定设置支撑片，铰链通过螺丝锁合在支撑片上。通常采用人工用电批锁紧螺丝。在人工锁螺丝作业过程中，由于作业手法、扭力等都有波动，使得柔性屏表面容易局部受力不均，出现凹凸不平等缺陷，影响柔性屏的平整度。
发明内容
为解决上述问题，本发明实施例公开一种提供提高柔性屏的平整度的电子设备及柔性装置。
第一方面，本发明实施方式提供一种柔性装置，包括柔性屏、支撑片及铰链，所述柔性屏包括可弯折区域，所述支撑片固定于所述可弯折区域，所述铰链通过胶体与所述支撑片背离所述柔性屏的一侧粘接。

为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图4为本发明一实施方式提供的电子设备的平面示意图。
图5为本发明第二实施方式提供的柔性装置的部分剖视图。
图6为本发明第三实施方式提供的柔性装置的部分剖视图。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，图1为本发明第一实施方式提供的电子设备的立体结构示意图。电子设备100包括第一框体101、第二框体102及柔性装置103。柔性装置103固定装设于第一框体101及第二框体102上，第一框体101及第二框体102用于支撑及保护柔性装置103。
本实施例中，电子设备100为手机。可以理解，在其它实施例中，电子设备100可以是但不限于无线电电话、平板电脑、游戏机、阅读器、寻呼机、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，简称GPS)接收器的个人数字助理(Personal Digital Assistant，简称PDA)。
请结合参阅图2，图2为沿图1所示的II-II线的部分剖视图。柔性装置103包括柔性屏10、支撑片30及铰链50。柔性屏10包括可弯折区域11。支撑片30固定于可弯折区域11。铰链50通过胶体60与支撑片30背离柔性屏10的一侧粘接。
由于通过胶体60将铰链50与支撑片30固定连接，柔性屏10不易产生表面局部受力不均的现象，提高了柔性屏10的平整度。另外，通常采用点胶设备进行自动化点胶，相较于人工锁螺丝固定的作业方式，有利于降低物料和生产成本，及提高生产效率。
本实施方式中，柔性屏10为柔性显示屏，可弯折区域11为柔性屏10的 局部区域，可弯折区域11位于柔性屏10的大致中部位置。可以理解，柔性屏10可以为柔性触控屏、柔性触控显示屏；不限定可弯折区域11设于柔性屏10的中部，柔性屏10的整个区域可以均为可弯折区域11。
支撑片30与柔性屏10层叠设置。支撑片30固定于柔性屏10的可弯折区域11，用于支撑可弯折区域11，以防止柔性屏10的可弯折区域11起拱。支撑片30具弹性变形能力。本实施方式中，支撑片30为钢片。柔性屏10背离支撑片30的一面为显示面。可以理解，不限定支撑片30为钢片，支撑片30也可以由其他具一定弹性的材料制成，例如弹性塑料片等。支撑片30包括相背设置的第一表面31及第二表面33，其中第一表面31朝向柔性屏10设置并与柔性屏10固定相接。
进一步地，柔性屏10包括层叠设置的屏体15及保护层17。保护层17与第一表面31固定连接，用于保护屏体15，防止支撑片30对屏体15造成磨损。本实施例中，保护层17是液态金属片，所述液态金属片固定贴合于屏体15的背面。所称液态金属是指将合金加热到熔融态，然后以超快的冷却速度冷却，使合金晶格来不及有序排列结晶便固化，因为是非结晶状态，像玻璃，所以又被称为非晶合金、液态金属或金属玻璃。液态金属的特性是长程无序(短程有序)、亚稳态、一定程度上的物理特性各向同性、没有确切熔点、具有玻璃转化温度点等，具有固态、金属、玻璃的特性，可以在一定条件下具有高强度、高硬度、塑性、热传导和耐磨性等。也就是说，所称的液态金属在常温实质上是固态的，只不过其某些特性接近液体，所以称之为液态金属。
在其他实施例中，不限定保护层17的制作材料，例如，保护层17可以是固定贴合于屏体15背面的耐磨塑胶片或耐磨橡胶片等等。
铰链50通过胶体60与支撑片30背离柔性屏10的一侧的第二表面33粘接，用于实现柔性屏10的弯折、展开。铰链50位于第一框体101与第二框体102之间。
电子设备100的柔性屏10通过铰链50折弯或展开时，铰链50能够相对第二表面33滑动，胶体60发生弹性变形，即胶体60产生将铰链50拉向支撑片30的作用力，而使支撑片30与铰链50保持相互靠近，减少铰链50与支撑片30脱离的可能性，从而防止柔性屏10因铰链50与支撑片30的分离而导致 的拱起，提高了柔性屏10的平整度。
换而言之，电子设备100的柔性屏10通过铰链50折弯或展开时，支撑片30与铰链50相对滑动，胶体60在支撑片30相对铰链50滑动时被拉伸变形，即胶体60类似于橡皮筋能够被拉伸变形，以补偿铰链50相对支撑片30运动时的弧长。
本实施方式中，胶体60为有机硅胶胶水固化而成的弹性胶体。可以理解，不限定胶体60为有机硅胶固化而成，其也可以为光敏胶胶水固化而成的弹性胶体，一实施例中，在点胶设备对铰链50的点光敏胶胶水完成后，光敏胶胶水通过紫外光照射后能固化，此时，所述光敏胶胶水固化成具有弹性的固态胶。
由于胶体60具有弹性，因而可以在铰链50相对支撑片30滑动时产生拉伸形变。当铰链50与支撑片30的相对位置恢复时，胶体60由于自身的弹性将自动收缩形变恢复初始状态，而不会出现被拉断的情况。
在一实施方式中，胶体60的形变程度与铰链50相对支撑片30的滑动距离成比例关系，即满足c
2＝a
2+b
2，其中c为胶体60拉伸变形之后的长度，a为铰链50相对于支撑片30的滑动距离，b为铰链50与支撑片30之间在厚度方向上的距离。换句话说，胶体60的拉伸幅度满足设定：设铰链50相对于支撑片30的滑动方向为X，支撑片30的厚度方向为Y，当铰链50相对于支撑片30滑动时，胶体60沿着相对X及厚度方向Y均倾斜的方向拉伸变形。
铰链50设有多个贯通铰链50设置的点胶孔51，用于容纳胶体60。点胶孔51包括连通设置的第一开口511及第二开口513，其中第一开口511为点胶孔51朝向支撑片30一侧的开口，第二开口513为点胶孔51背离支撑片30的一侧的开口。点胶孔51内的弹性胶体60通过第一开口511与支撑片30朝向铰链50的第二表面33粘接。本实施方式中，第一开口511的口径小于第二开口513。点胶时，点胶设备的点胶针头从第二开口513伸入进行点胶，胶水从第一开口511流出至支撑片30，胶水固化后形成粘接点胶孔51内壁与支撑片30的胶体60。
本实施方式中，胶体60未填满整个点胶孔51，及并未填满第一开口511。可以理解，胶体60可以填满整个点胶孔51。可以理解，胶体60可以填满第一开口511，以防止灰尘等杂物通过第一开口511进入支撑片30与铰链50之 间，影响柔性屏10的平整度。
由于通过凹设于铰链50背离支撑片30的一侧的第二开口513进行点胶，方便了点胶设备的点胶操作，以及防止溢胶污染铰链50的其余区域。由于点胶孔51贯通于铰链50，通过控制第一开口511朝向支撑片30一端的口径大小，有利于控制胶体60与支撑片30的接触面积，连接于胶体60拉伸变形时的形变量，防止支撑片30与铰链50分离，柔性屏10不会发生拱起。
请参阅图3，图3为本发明一实施方式提供的电子设备的省略部分结构的示意图。铰链50包括第一区域501及两个第二区域503。第一区域501位于两个第二区域503之间。第一区域501大致位于铰链50的中部，每个第二区域503大致位于铰链50的端部。
多个点胶孔51位于铰链50的第一区域501。本实施方式中，铰链50可绕平行于第一方向的轴线旋转弯曲，第二开口513的较长边沿第一方向延伸，第二开口513的较短边沿垂直第一方向的第二方向延伸。第一开口511大致呈条形，第一开口511的较长边沿垂直第一方向的第二方向延伸，有利于释放铰链50在折弯或展开柔性屏10时产生的应力，从而提高铰链50的使用寿命。贯通部513的较长边的长度与容纳部511的较短边的长度大致相同。可以理解，不限定第一开口511、第二开口513的形状，可以为圆形、三角形等其他形状。
铰链50于第二区域503内贯通设有多个第一通孔55，电子设备100还包括多个第一锁紧件70。每个锁紧件70穿过一个第一通孔55与支撑片30固定连接。本实施方式中，锁紧件70为螺丝。电子设备100的柔性屏10通过铰链50折弯或展开时，铰链50相对第二表面33滑动，锁紧件70能够产生将铰链50拉向支撑片30的作用力，而使支撑片30与铰链50保持相互靠近，减少铰链50与支撑片30脱离的可能性，从而防止柔性屏10因铰链50与支撑片30的分离而导致的拱起，提高了柔性屏10的平整度。
可以理解，不限定点胶孔51的分布区域，点胶孔51可以分布于第一区域501、第二区域503及/或铰链50的其他区域，实现铰链50与支撑片30通过胶体60粘接即可。
可以理解，可以省略锁紧件70，通过对第一通孔55进行点胶形成胶体60，第一通孔55内的胶体60与第一通孔55的内壁及支撑片30粘接。
可以理解，请参阅图4所示，图4为本发明一实施方式提供的铰链的区域示意图。铰链50于第一区域501内贯通开设多个第二通孔57，柔性装置还包括第二锁紧件80，第二锁紧件80穿设于第二通孔57并与支撑片固定相接。第二通孔57间隔点胶孔51设置。通过胶体60粘接及锁紧件70锁合两种方式，将铰链50固定于支撑片30上。
请参阅图5所示，图5为本发明第二实施方式提供的柔性装置的部分剖视图。第二实施方式提供的柔性装置与第一实施方式提供的柔性装置的结构大致相同，不同在于，点胶孔51凹设于铰链50朝向支撑片30的一侧，点胶孔51不为通孔。
请参阅图6所示，图6为本发明第三实施方式提供的柔性装置的剖面示意图。第三实施方式提供的柔性装置与第一实施方式提供的柔性装置的结构大致相同，不同在于，支撑片30的第二表面33具有凹槽331，用于收容胶体60。点胶设备通过第二开口513于点胶孔51内点胶，胶水从第一开口511流入凹槽33内，从而将铰链50与支撑片30粘接。由于第二表面33具有收容胶体60的凹槽331，防止胶体60进入第二表面33的其他区域，造成铰链50与支撑片30之间的不平整，有利于提高柔性屏的平整度。
可以理解，可以省略点胶孔51，于支撑片30朝向铰链50的一面涂覆胶水，及/或于铰链50朝向支撑片30的一面涂覆胶水，胶水固化后形成固态的胶体60，实现连接支撑片30与铰链50。
以上所述是本发明的优选实施例，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
