请一并参阅图1至图3，图1是本申请第一实施例中的电子装置的立体结 构示意图；图2是图1中沿II-II线的剖视图；图3是图2的分解示意图。本申请的第一实施例中的电子装置100包括一壳体20及设置于所述壳体20上的一柔性显示装置30。所述壳体20包括一第一框体21、一第二框体23及连接于所述第一框体21与所述第二框体23之间的一铰链25。所述柔性显示装置30设置于所述第一框体21、第二框体23及所述铰链25上。所述柔性显示装置30设置有对应所述铰链25的一可折弯区域31及连接于所述可折弯区域31的非折弯区域。所述柔性显示装置30包括一柔性屏32及设置于所述柔性屏32背面的一保护片34，所述柔性屏32的正面为显示面。所述保护片34覆盖所述可折弯区域31。所述保护片34用于防止所述柔性屏32在弯曲时受到摩擦，即，所述保护片34用于保护所述柔性屏32本身及其背面的层叠材料层，防止所述柔性屏32及层叠村料层对应所述可折弯区域31的区域被磨损。所述保护片34可以是耐磨薄片。
本实施例中，所述保护片34可以是硅胶、泡棉、薄金属片如铜箔、液态金属片、记忆合金或其他符合材料。
本实施例中，所述保护片34是液态金属片，所述保护片34的正面贴接于所述柔性屏32的背面，所述保护片34的背面贴接于所述铰链25上。具体的，所述柔性屏32的背面与所述保护片34之间对应所述可折弯区域31的区域能相对滑动，所述柔性屏32的背面与所述保护片34之间对应所述非折弯区域固定贴合；所述保护片34与所述铰链25之间固定连接。当所述电子装置100通过所述铰链25折弯或展平时，所述保护片34与所述柔性屏32之间对应所述可折弯区域31的区域内相对滑动。所述柔性屏32的正面指所述柔性屏32的出光面，所述柔性屏32的背面指背朝所述出光面的面。
本发明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，本发明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。所述液态金属可以为铜、钛、铁、锆、银、镍、镓、金、锑、镉、锌、铟、硅等 中一种或多种材料的合金材料，具体金属优选可获得更低的弹性模量、硬度、延伸性等其他力学性质。
所述保护片34覆盖所述柔性屏32的背面的非折弯区域，这种全覆盖的方式可以避免在保护片34的相对两侧出现段差，导致柔性屏32出现褶皱或外观不良的情况。
在其他实施例中，所述柔性屏32的背面与所述保护片34之间对应所述可折弯区域31及非折弯区域均固定贴合；所述保护片34与所述铰链25之间对应所述可折弯区域31的区域能相对滑动，所述保护片34与所述第一框体21及第二框体23之间固定贴合。当所述电子装置100通过所述铰链25折弯或展平时，所述保护片34与所述铰链25之间相对滑动。
本实施例中选用液态金属片作为保护片34的原因在于液态金属片的耐磨性较佳，当其通过光学胶等方式贴设于柔性屏32的背面时，不仅可以支撑所述柔性屏32，并且可以有效地抵御铰链25对其产生的摩擦，不易出现磨损的情况。另一方面，液态金属片的弹性模量较低，可将其直接粘贴在柔性屏32的背面，在柔性显示装置30弯曲时可跟随柔性屏32一起同步或近似同步拉伸，从而避免柔性显示装置30在弯曲时由于拉伸幅度差异较大导致出现破损的情况。液态金属可选用铜基、钛基、铁基、锆基、银基、镍基、镓基、金基、锑基、镉基、锌基、铟基、硅基等液态金属，并且，相比于现有的弹性模量更低的材料，如硅胶、泡棉、塑胶等，液态金属的强度更高，且耐磨性更佳，可有效地对柔性屏进行支撑。
优选地，所述保护片34的弹性模量大于柔性屏32的弹性模量，保护片34与柔性屏32的弹性模量之差(柔性屏的弹性模量为各膜层的平均弹性模量)大于或等于100Gpa并小于或等于120Gpa，更优选地，小于或等于100Gpa。由于柔性屏的各层膜材(如发光层、基底层、阴极层、阳极层、TFT层等)的弹性模量均在较低范围，如果采用常用的金属片，如钢板、铝板等材料作为保护层直接与柔性屏贴合固定，那么由于常见金属片的弹性模量远大于柔性屏各层膜材的弹性模量，在与柔性屏一同弯折时将容易由于出现拉伸量差异过大而导致柔性屏损坏的情况。因此，本发明采用弹性模量与柔性屏匹配更加接近的液态金属作为保护片，其相比于常见的金属片(如钢片、铝片、铁片等)，弹性模量更接近于柔性屏，且能提供充分的硬度支撑柔性屏，是较为理想的材料。液 态金属保护片34与柔性屏32的弹性模量之差(柔性屏的弹性模量为各膜层的平均弹性模量)大于或等于100Gpa并小于或等于120Gpa，更优选地，小于或等于100Gpa。更优选地，本发明实施例的液态金属保护片的厚度介于5微米(μm)与200微米之间(含本数)。此厚度范围的液体金属保护片能给柔性屏32提供充分的支撑力，且弯折性能优良，可避免保护片34过厚而影响柔性屏弯折的情况。进一步地，液态金属保护片的厚度介于5微米与50微米之间(含本数)，以获得更加理想的弯折性能。
在其他实施例中，所述保护片34还可以是软质耐磨塑胶片、软质耐磨橡胶片或软质硅胶片等。本实施例中，所述电子装置100为手机。可以理解，在其它实施例中，电子装置100可以是但不限于无线电电话、寻呼机、Web浏览器、记事簿、日历以及/或全球定位系统(GPS)接收器的PDA。
本申请电子装置100的柔性屏32的背面设置有保护片34，即，所述柔性屏32的背面对应所述可折弯区域31处与所述铰链25之间是通过所述保护片34接触。当所述电子装置100通过所述铰链25折弯或展平时，所述柔性屏32与所述保护片34之间于所述可折弯区域31处相对滑动，或者所述保护片34与所述铰链25之间相对滑动。由于所述保护片34具有保护作用，因此，所述柔性屏32的背面在所述电子装置100折弯或展平的过程中不会被磨损，故此可确保所述柔性屏32的功能不受影响，另外，所述保护片34还具有支撑所述柔性屏32的作用。
所述第一框体21远离所述第二框体23的一端开设有一导滑槽212，所述导滑槽212内滑动地设置有一滑块214，所述滑块214与所述第一框体21之间沿所述滑块214的滑动方向设置有一弹性件216。本实施例中，所述保护片34的一端固定贴合于所述第二框体23上，所述保护片34的另一端固定贴合于所述第一框体21上，所述保护片34的中部固定于所述铰链25。所述柔性屏32的一端固定贴合于所述滑块214上，所述柔性屏32的另一端固定贴合于所述保护片34的正面对应所述第二框体23的区域上，所述柔性屏32与所述保护片34对应所述可折弯区域31的区域不固定贴合，即，所述柔性屏32的背面与所述保护片34之间在所述可折弯区域31处滑动接触，以便于所述柔性显示装置30折弯与展平。所述弹性件216弹性抵推所述滑块214朝远离所述第二框体23的一端滑动，以向外拉直所述柔性屏32，避免所述电子装置100 在折弯/展平时，所述柔性屏32对应所述可折弯区域31的区域与所述保护片34分离而拱起。
本实施例中，所述弹性件216是弹簧，所述弹簧的一端连接于所述第一框体21，所述弹簧的另一端连接于所述滑块214。
进一步地，所述柔性屏32背面也可设置遮光黑胶层，所述保护片34固定贴合在柔性屏32的遮光黑胶层的背面上，以起到防止或减小柔性屏32的遮光黑胶层被磨损。
如图2所示，所述柔性屏32包括一屏体322、贴设于所述屏体322的背面的一支撑膜324，以及盖设于所述屏体322的正面的一盖板326，所述支撑膜324通过光学背胶328贴接于所述屏体322的背面。所述屏体322即为显示图像的主体。本实施例中，所述保护片34的正面与所述支撑膜324的背面之间对应所述可折弯区域31滑动贴合，所述保护片34固定贴合于所述第一框体21、所述第二框体23及铰链25上。当所述电子装置100通过所述铰链25折弯或展平时，所述保护片34的正面与所述支撑膜324的背面之间对应所述可折弯区域31的区域相对滑动，由于所述保护片34及所述支撑膜324对所述屏体322均具有保护作用，因此，所述保护片34及所述支撑膜324均能防止所述铰链25磨损所述屏体322。
所述支撑膜324可以是PET膜、PI膜或PC膜等。
所述支撑膜324与所述滑块214之间也层叠有光学胶，以使所述柔性屏32与所述滑块214的连接更牢固。所述保护层34与所述所述第一框体21及所述第二框体23之间层叠有光学胶，从而使所述柔性屏32与所述第一框体21及第二框体23的连接更牢固。
在其他实施例中，所述保护片34的正面通过光学胶贴接于所述支撑膜324的背面，即，所述保护片34面朝所述屏体322的侧面固定贴合于所述支撑膜324背朝所述屏体322的侧面，所述保护片34的背面与所述铰链25之间滑动贴合。当所述电子装置100通过所述铰链25折弯或展平时，所述保护片34的背面与铰链25之间相对滑动。由于所述屏体322与所述铰链25之间设置有保护片34，所述保护片34具有耐磨性，因此，所述电子装置100在折弯或展平时不会磨损到所述屏体322。
请参阅图4，图4是本申请第二实施例中的电子装置的部分剖视结构示意 图。本申请的电子装置的第二实施例的结构与第一实施例的结构相似，不同之处在于：第二实施例中，所述柔性显示装置30还包括具有弹性的一支撑片36，所述支撑片36设置所述保护片34的背面，即，所述支撑片36夹设于所述保护片34与所述铰链25之间。所述保护片34的弹性模量小于所述支撑片36的弹性模量。进一步地，所述保护片34的弹性模量与柔性屏32的弹性模量的差值小于支撑片36的弹性模量与保护片34的弹性模量的差值。本实施例中，所述支撑片36覆盖所述第一框体21、第二框体23及铰链25，所述支撑片36随所述铰链25的折弯或展平而弯曲或平铺。
所述支撑片36可以是液态金属片、软质耐磨塑胶片、软质耐磨橡胶片或软质硅胶片等。所述支撑片36也可以由如四氟乙烯层、石墨、二硫化钼或热塑性聚氨酯弹性体橡胶等材料制成。
本实施例中，所述支撑片36是能弯曲的钢片，具体的，所述钢片为不锈钢薄片。所述钢片的厚度大于或等于5微米并小于或等于300微米
本实施例中，所述保护片34通过光学胶、UV胶、背胶等方式固定于柔性屏32的背面。保护片34可全贴合于柔性屏32的整个背面，也可以仅贴合于柔性屏背面的可折弯区域31，即只有在柔性屏32背面的可折弯区域31贴有保护片34，非弯曲区域无保护片34分布。所述支撑片36的背面的一端固定贴合于所述第二框体23上，所述支撑片36的另一端固定贴合于所述第一框体21上，所述支撑片36的中部固定连接于所述铰链25上。具体的，所述支撑片36通过胶接、焊接或卡接等方式固定于所述第一框体21、所述第二框体23及所述铰链25上。所述保护片34与所述支撑片36之间对应所述可折弯区域31的区域相对滑动，所述保护片34与所述支撑片36之间对应所述第二框体23的区域固定贴合。当所述电子装置100通过所述铰链25折弯或展平时，所述保护片34与所述支撑片36之间在所述可折弯区域31的区域内相对滑动，从而能有效地防止所述铰链25磨损到所述柔性屏32。
支撑片36的厚度介于5微米与300微米之间(含本数)，以获得较佳的弯折性能。优选地，支撑片36的厚度大于保护层的厚度，以提供更充分的支撑力度。支撑片36的强度大于保护片34的强度。
在其他实施例中，所述保护片34与所述支撑片36之间对应所述可折弯区域31的区域、所述柔性屏32与所述保护片34之间对应所述可折弯区31的区 域，或者所述支撑片36与所述铰链25之间均可以涂设有助滑物质，更便于所述电子装置100的折弯或展平。
请参阅图5，图5是本申请第三实施例中的电子装置的部分剖视结构示意图。本申请的电子装置的第三实施例的结构与第二实施例的结构相似，不同之处在于：第三实施例中，所述保护片34与所述支撑片36通过弹性胶38连接，所述支撑片36固定贴合于所述铰链25。具体的，所述保护片34于所述可折弯区域31的相对的两外侧边与所述支撑片36之间分别设置有所述弹性胶38。当所述柔性屏30弯曲时，所述支撑片36与所述保护片34在所述可折弯区域31的区域相对滑动，所述弹性胶38在所述保护片34相对所述支撑片36滑动时产生拉伸变形。所述弹性胶38不仅能防止所述保护片34与所述支撑片36在折弯或展平的过程中不分离，并且能防止外部的灰尘进入所述保护片34与所述支撑片36之间而影响所述电子装置的折弯或展平。
本实施例中，所述弹性胶50是光敏胶，所述弹性胶50通过紫外光照射后能固化，固化成的所述弹性胶50具有弹性。
在其他实施例中，所述弹性胶50也可以是有机硅胶胶水，所述有机硅胶胶水固化后具有弹性。
所述弹性胶50在所述可折弯区域31内沿所述柔性屏32的外侧边的长度方向延伸。
请参阅图6，图6是本申请第四实施例中的电子装置的部分剖视结构示意图。本申请的电子装置的第四实施例的结构与第三实施例的结构相似，不同之处在于：在第四实施例中，所述支撑片36面朝所述保护片34的侧面沿所述柔性屏32的外侧边的长度方向开设有胶槽362，即，所述支撑片36的正面沿所述柔性屏32的外侧边的长度方向开设有所述胶槽362。所述弹性胶38收容于所述胶槽362内并贴粘于所述保护片34与所述支撑片36之间。即，所述胶槽362内的弹性胶38延伸出所述支撑片36面朝所述保护片34的侧面，以方便所述支撑片36与所述保护片34的连接。所述胶槽362能增大所述弹性胶38与所述支撑片36的接触面积，从而使所述弹性胶38与所述支撑片36及所述保护片34的粘贴更牢固。
请参阅图7，图7是本申请第五实施例中的电子装置的正面结构示意图。 本申请的电子装置的第五实施例的结构与第三实施例的结构相似，不同之处在于：在第五实施例中，所述支撑片36与所述保护片34之间在所述可折弯区域31的区域内设置有相互间隔的若干弹性胶38，每一弹性胶38沿所述柔性屏32的外侧的长度方向延伸。
在其他实施例中，所述支撑片36面朝所述保护片34的侧面或所述保护片34面朝所述支撑片36的侧面开设有相互间隔的若干胶槽，每一胶槽沿所述柔性屏32的外侧的长度方向延伸。每一胶槽内填充有弹性胶，每一胶槽内的弹性胶连接于支撑片36及保护片34。
在其他实施例中，所述弹性胶50可以是在所述可折弯区域31内沿所述柔性屏32的外侧边的长度方向排列的若干个弹性胶块。
请参阅图8及图9，图8是本申请第六实施例中的电子装置的部分剖视结构示意图；图9是图8的分解示意图。本申请的电子装置的第六实施例的结构与第三实施例的结构相似，不同之处在于：第六实施例中，所述支撑片36面朝所述柔性屏32的侧面对应所述可折弯区域31开设有一收容槽364，即，所述支撑片36的正面开设有所述收容槽364，所述保护片34收容于所述收容槽364内。所述支撑片36的背面通过粘胶、焊接、螺锁、卡扣、磁吸等方式固定贴接于所述铰链25的正面，所述保护片34的正面通过所述光学胶、UV胶、背胶等粘胶固定贴接于所述支撑膜324的背面，此时，所述支撑片36面朝所述柔性屏32的侧面与所述保护片34面朝所述柔性屏32的侧面齐平。参见图10，所述收容槽364沿所述柔性屏32的外侧的长度方向的长度大于所述保护片34沿所述柔性屏32的外侧的长度方向的长度，即，所述保护片34相对的两端面与所述收容槽364相对的两内侧面之间分别设有间隙365。所述收容槽364的长度略大于保护片34的长度。
本实施例中，所述收容槽364覆盖所述可折弯区域31，即，所述收容槽364的开孔面积大于或等于所述可折弯区域31的区域面积。所述保护片34的背面滑动贴接于所述收容槽364的面朝所述柔性屏32的内表面。所述保护片34的背面是所述保护片34背朝所述柔性屏32的侧面，所述收容槽364朝向所述保护片34的内表面为收容槽364的槽底。当所述电子装置100通过所述铰链25折弯或展平时，所述保护片34的背面与所述收容槽364的槽底之间相对滑动，从而能防止所述铰链25磨损所述柔性屏32。
在其他实施例中，保护片34的背面与收容槽364的槽底之间有间隙，具体的，所述保护片374的背面与收容槽346的槽底之间的距离大于或等于10微米并小于或等于300微米。当所述电子装置100通过所述铰链25折弯或展平时，所述保护片34的背面与所述收容槽364的槽底之间相对滑动，但所述保护片34的背面不接触所述收容槽364的槽底。
在其他实施例中，所述收容槽364的开孔面积可以小于所述可折弯区域31的面积。
在其他实施例中，所述收容槽364可穿通所述支撑片36的背面，所述保护片34的背面与所述支撑片36的背面齐平，即，所述保护片34背朝所述柔性屏32的侧面与所述支撑片36背朝所述柔性屏32的侧面齐平。
在其他实施例中，所述保护片34的背面与所述收容槽364的面朝所述柔性屏32的内表面之间设置有助滑物质。
请参阅图10及图11，图10是本申请第七实施例中的电子装置的部分剖视结构示意图；图11是图10中的XI部分的放大图。本申请的电子装置的第七实施例的结构与第六实施例的结构相似，不同之处在于：第七实施例中，保护片34的背面与所述收容槽364的面朝所述柔性屏32的内表面之间有间隙366。当所述电子装置100通过所述铰链25折弯或展平时，所述保护片34在所述收容槽364内滑动，但所述保护片34的背面与所述收容槽364的内表面之间具有间隙365、366而不会摩擦接触，从而能更好地防止所述柔性屏32被磨损。
图8-11的实施例中，保护片34可以是液态金属，支撑片36可以是不锈钢板。液态金属的厚度为5微米至200微米之间(含本数)，不锈钢板的厚度为50微米至300微米之间(含本数)。在图10-11的实施例中，间隙366的宽度(即保护层的背面与收容槽面朝柔性屏的内表面之间的距离)为5微米至300微米(含本数)。通过维持间隙宽度在上述范围，可以有效降低保护片34与支撑片366之间的摩擦，并得以控制整机的厚度。
可以理解地，除屏体322外，本发明的柔性屏32也可以不包含或仅包含盖板326及支撑膜324其中的任一种或多种或所有。
可以理解地，本发明所称“相对滑动”并不限定两个元件之间直接接触并相对滑动，而是还可以包含间隔第三方元件相对滑动，第三方元件也并不限于 实体元件，如片材、膜材等，而是还可以包含非实体元件，如间隙、空间等，或者是实体元件与非实体元件的组合；第三方元件也并不限定为一个，而是可以包含多个。也就是说，只要两个元件有相对滑动的运动关系，不管两个元件的实际位置如何，都可以认为是本发明所称的“相对滑动”的范围内。
以上所述是本发明的优选实施方式，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。
