所述第一弹性胶50为条形状，所述第一弹性胶50沿所述柔性屏33的外侧的长度方向延伸，即，所述第一弹性胶50沿所述柔性屏33的长度方向延伸。
本实施例中，所述支撑片31的宽度大于所述保护层334的宽度，即，所述支撑片31的相对的两外侧分别延伸超出所述保护层334的相对两外侧。所述保护层334的相对两外侧的侧面与所述支撑片31延伸超出所述保护层334的正面之间分别点设有所述第一弹性胶50。所述两外侧为所述电子装置100的可折弯区域335的两外侧。
本实施例中，所述保护层334是液态金属片，所述液态金属片固定贴合于所述屏体332的背面；所述胶体是光敏胶，即，所述电子装置100的所述保护层334与所述支撑片31之间点胶完成后，所述胶体通过紫外光照射后能固化，此时，所述胶体固化成具有弹性的固态胶。
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。

本实施例中，所述柔性屏板3321的宽度小于所述盖板3323的宽度而相对于所述盖板3323内缩，有利于所述盖板3323更好地保护所述柔性屏板3321；所述保护层334的宽度与所述柔性屏板3321的宽度相同。

请一并参阅图10及图11，图10是本申请的第九实施例中的电子装置的结构示意图；图11是图10中沿XI-XI线的剖视图。本申请电子装置的第九实施例的结构与第一实施例的结构相似，不同之处在于：第九实施例中，所述支撑片31背朝所述保护层334的侧面对应所述可折弯区域335处开设有贯通部315，所述贯通部315沿所述支撑片31的厚度方向贯穿所述支撑片31，贯通部315内填充有胶体。本实施例中，所述贯通部315包括多个定位孔，每一定位孔内设有所述胶体，每一定位孔内的胶体为一第二弹性胶54。这些定位孔 均为通孔，呈矩阵式分布于支撑片31上，即各个所述第二弹性胶54沿着所述柔性屏33的变曲轴的方向排列。每一定位孔延伸至所述保护层334，每一定位孔内的第二弹性胶54连接于所述支撑片31与所述保护层334，使所述电子装置100在折弯或展平时，所述支撑片31与所述保护层334不分离。这些定位孔位于所述可折弯区域335相对的两外侧的两个第一弹性胶50之间。注入定位孔的第二弹性胶54形成类似于螺钉结构，所述第二弹性胶54包括收容于所述贯通部315内的杆部542，以及外露于所述贯通部315的头部544。所述头部544粘接所述支撑片31，头部544的直径大于杆部542的直径。第二弹性胶54的杆部542末端与保护层334粘接，杆部542侧壁及头部544与支撑片31粘接，即，所述杆部542粘接所述支撑片31的贯通部315的内侧壁及所述柔性屏33的背面，以将柔性屏33与支撑片31进一步连接起来。通过定位孔内的第二弹性胶54，可以进一步防止柔性屏33的可折弯区域335的中部在变形时发生拱起或翘起的现象。本实施例中，第二弹性胶54可采用光固化胶制成，即在点胶之后，通过UV等方式进行固化。本实施例的弹性胶可以和前述实施例的相同，也可以不同。
应当理解地，本发明实施例提供了多种固定支撑片与保护层的方式，不管是侧面封胶还是中部点胶，每一种方式均单独可实现在厚度方向固持支撑片与柔性屏，在支撑片延伸方向上滑动连接支撑片与柔性屏的目的，从而防止支撑片与柔性屏分离。换句话说，通过侧面封胶与中部点胶任一种方式，支撑片与柔性屏在相对滑动的过程中，支撑片与柔性屏之间在厚度方向的距离被维持住，而在支撑片延伸方向的相对位移则不受弹性胶或胶水的影响。还可以理解地，除了侧面封胶与中部点胶之外，其他任意位置的弹性胶或胶水，只要能确保连接支撑片与柔性屏且具备一定的弹性，均可以实现上述效果。
还可以理解地，第一弹性胶50与第二弹性胶54可以相同，也可以不同，只要能够起到粘接上下两侧的元件并具备一定的弹性的粘胶都可以适用于本发明。
请参阅图12，图12是本申请的第十实施例中的电子装置的结构示意图。本申请电子装置的第十实施例的结构与第五实施例的结构相似，不同之处在于：第十实施例中，所述支撑片31背朝所述保护层334的侧面对应所述可折弯区域335处开设有贯通部315，所述贯通部315沿所述支撑片31的厚度方向贯穿所述支撑片31，贯通部315内填充有第二弹性胶54。本实施例中，贯通部315包括多个定位孔，每一定位孔内设有所述第二弹性胶54，这些定位孔均为通孔，呈矩阵式分布于支撑片31上，即各个所述第二弹性胶54沿着所述柔性屏33的变曲轴的方向排列，每一定位孔延伸至所述保护层334，每一定位孔内的第二弹性胶54连接于所述支撑片31与所述保护层334，使所述电子装置100在折弯或展平时，所述支撑片31与所述保护层334不分离。这些定位孔位于所述可折弯区域335相对的两外侧的两个第一弹性胶50之间。注入定位孔的第二弹性胶54形成类似于螺钉结构，所述第二弹性胶54包括收容于所述贯通部315内的杆部542，以及外露于所述贯通部315的头部544。所述头部544粘接所述支撑片31，头部544的直径大于杆部542的直径。第二弹性胶54的杆部542末端与保护层334粘接，杆部542侧壁及头部544与支撑片31粘接，即，所述杆部542粘接所述支撑片31的贯通部315的内侧壁及所述柔性屏33的背面，以将柔性屏33与支撑片31进一步连接起来。通过定位孔内的第二弹性胶54，可以进一步防止柔性屏33的可折弯区域335的中部在变形时发生拱起或翘起的现象。本实施例中，第二弹性胶54可采用光固化胶制成，即在点胶之后，通过UV等方式进行固化。本实施例的弹性胶可以和前述实施例的相同，也可以不同。
请一并参阅图13及图14，图13是本申请的第十一实施例中的电子装置的结构示意图，图14是图13中沿XIV-XIV线的剖视图。本申请电子装置的第十一实施例的结构与第九实施例的结构相似，不同之处在于：第十一实施例中，所述支撑片31背朝所述保护层334的侧面对应所述可折弯区域335处开设有贯通部317，所述贯通部317包括多个定位槽，这 些定位槽沿所述柔性屏33的弯曲轴的方向排列，每一定位槽沿着垂直于所述弯曲轴的方向延伸，即，每一定位槽沿所述填充槽37的长度方向延伸，且每一定位槽沿所述支撑片31的厚度方向贯穿所述支撑片31。每一定位槽内填充有具有弹性的第二弹性胶54，每一定位槽内的第二弹性胶54连接于支撑片31及保护层334。当所述电子装置100在折弯或展平时，所述定位槽内的第二弹性胶54能使所述支撑片31与所述保护层334不分离。定位槽的长度小于可折弯区域335的长度，即小于所述第一弹性胶50的长度。这些定位槽位于所述可折弯区域335相对的两外侧的两个第一弹性胶50之间。注入每一定位槽的胶水形成类似于螺钉结构，包括位于定位槽内的杆部542及位于定位槽外的头部544。头部544的直径大于杆部542的直径。第二弹性胶54的杆部542末端与保护层334粘接，杆部542侧壁及头部544与支撑片31粘接，以将保护层334与支撑片31进一步连接起来。通过定位槽内的第二弹性胶54，可以进一步防止柔性屏33的可折弯区域335的中部在变形时发生拱起或翘起的现象。本实施例中，第二弹性胶54可采用光固化胶制成，即在点胶之后，通过UV等方式进行固化。此外，本实施例中的第二弹性胶54可以和第一弹性胶50相同，即注入定位槽内的也可以是第一弹性胶50。由于注入定位槽内的第二弹性胶54也是沿可折弯区域335的长度方向延伸，因而可有效减少折弯时对于第二弹性胶54产生的应力，防止第二弹性胶54脱落。进一步地，本实施例的第二弹性胶54是呈条状分布，使得保护层334与支撑片31的粘接面积更大，有利于提升保护层334与支撑片31之间的粘接力。
可以理解地，除屏体外，本发明的柔性屏也可以不包含或仅包含遮光黑胶层、保护层及盖板其中的任一种或多种或所有。
还可以理解地，请参阅图15，为本申请的第十二实施例的电子装置的结构图。本实施例中，电子装置为倒置形态，在可折弯区域335中，其支撑片31位于上层，柔性屏33位于下层。保护层334、遮光黑胶层3325、柔性屏板3321及盖板3323依次层叠于支撑片31下方。支撑片31的宽度小于保护层334的宽度，柔性屏板3321、遮光黑胶层3325的宽度小于保护层334的宽度，盖板3323的宽度大于保护层334的宽度。第一弹性胶50设于支撑片31与保护层334在可折弯区域335相对两侧之间，即第一弹性胶50连接支撑片31在可折弯区域335的每一外侧面与保护层334在可折弯区域335的相应上侧面，以起到密封防尘作用。具体地，保护层334的相对两外侧延伸超出支撑片31的两侧边缘，第一弹性胶50连接支撑片31的外侧面及保护层334超出支撑片31的一侧。由于保护层334的宽度大于支撑片31的宽度，因而在点胶时可以防止第一弹性胶50从保护层334上溢出至盖板3323上。本实施例中，第一弹性胶50可以为光固化胶，即在点胶完成之后通过UV等光线进行固化。更进一步地，由于电子装置100为倒置形态，因而可以继续如图10-14所示的注入第二弹性胶54的步骤。即在点第一弹性胶50之后，可以继续在支撑板52的定位孔或定位槽内点入第二弹性胶54，第二弹性胶54具体的结构及形态可参见上述关于图10-14的实施例。也就是说，这种倒置点胶方式可以使得第一弹性胶50及第二弹性胶54在同一制程中完成，可简化制作过程。当然，也可以先点第二弹性胶54，再点弹性胶，二者顺序可以根据实际需求来调整。
上述各实施例的第一弹性胶50及第二弹性胶54均具有弹性，因而可以在支撑片31相对柔性屏33滑动时产生拉伸形变，当支撑片31与柔性屏33的相对位置恢复时，第一弹性胶50及第二弹性胶54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。进一步地，第一弹性胶50与第二弹性胶54的形变程度与支撑片31相对柔性屏33的滑动距离成比例关系，即满足c2＝a2+b2，其中c为第一弹性胶50与第二弹性胶54拉伸变形之后的长度，a为支撑片31相对于柔性屏33的滑动距离，b为支撑片31与柔性屏33之间在厚度方向上的距离。换句话说，第一弹性胶50与第二弹性胶54的拉伸幅度满足
Figure PCTCN2018098644-appb-000001
设定当支撑片31相对柔性屏33滑动方向为X，支撑片31的厚度方向为 Y，当支撑片31相对柔性屏33滑动时，第二弹性胶54与第一弹性胶50沿着相对X及厚度方向Y均倾斜的方向拉伸变形。
在上述各实施例中，所述第一弹性胶50的粘度小于所述第二弹性胶54的粘度，所述第一弹性胶50及第二弹性胶54粘接于所述保护层334与所述支撑片31。
