具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
请参阅图1和图2，图1是本申请实施例提供的一种可折叠终端1000在一种状态下的结构示意图，图2是图1所示可折叠终端1000在第二种状态下的结构示意图。
其中，为了便于描述，定义图2所示可折叠终端1000的宽度方向为X轴方向，可折叠终端1000的长度方向为Y轴方向，可折叠终端1000的厚度方向为Z轴方向，X轴方向、Y轴方向和Z轴方向两两相互垂直。
可折叠终端1000可以为手机、平板电脑、个人计算机、多媒体播放器、电子书阅读器、笔记本电脑、车载设备或可穿戴设备等可折叠的电子产品。本实施例中，可折叠终端1000 为可折叠手机。即，可折叠终端1000为可以在折叠状态和展开状态之间切换的手机。本申请实施例中，以可折叠终端1000可沿X轴方向发生折叠或者展开为例进行说明。
其中，图1所示可折叠终端1000处于折叠状态，图2所示可折叠终端1000处于展开状态。示例性的，图2所示可折叠终端1000的展开角度α为180度。即，图2所示可折叠终端1000处于展平状态。需要说明的是，本申请实施例举例说明的角度均允许存在少许偏差。例如，图2所示可折叠终端1000的展开角度α为180度是指，α可以为180度，也可以大约为180度，比如170度、175度、185度和190度等。后文中举例说明的角度可做相同理解。
应当理解的是，本申请实施例所示可折叠终端1000为可发生一次折叠的终端。在其他一些实施例中，可折叠终端1000也可以为可发生多次(两次以上)折叠的终端。此时，可折叠终端1000可以包括多个部分，相邻两个部分可相对靠近折叠至可折叠终端1000处于折叠状态，相邻两个部分可相对远离展开至可折叠终端1000处于展开状态。
请一并参阅图3，图3是图1所示可折叠终端1000沿I-I处剖开的剖面结构示意图。其中，沿“I-I处剖开”是指沿I-I线所在的平面剖开，后文相关的类似描述可做相同理解。
本实施例中，可折叠终端1000包括可折叠装置100、显示屏200、装饰件300和防尘件400。可折叠装置100设有第一安装槽101和第二安装槽102，第二安装槽102环绕第一安装槽101设置。显示屏200安装于第一安装槽101，装饰件300安装于第二安装槽102，且环绕显示屏200设置。防尘件400位于显示屏200与装饰件300之间。
在其他一些实施例中，显示屏200可以不安装于第一安装槽101，而安装于可折叠装置100的其他位置，和/或，装饰件300可以不安装于第二安装槽102，而安装于可折叠装置100的其他位置，本申请实施例对显示屏200和装饰件300与可折叠装置100之间的装配关系不作具体限定。
可折叠装置100包括第一壳体110、第二壳体120以及转动机构130，转动机构130连接于第一壳体110和第二壳体120之间，以实现第一壳体110和第二壳体120之间的转动连接。第一壳体110和第二壳体120可通过转动机构130相对转动，使得可折叠装置100在折叠状态和展开状态之间相互切换。具体的，第一壳体110和第二壳体120可相对转动至相对设置，以使可折叠装置100处于折叠状态，如图1所示。此时，转动机构130处于折叠状态。第一壳体110和第二壳体120也可相对转动至相对展开，以使可折叠装置100处于展开状态，如图2所示。此时，转动机构130处于展开状态。示例性的，图2所示可折叠终端1000处于展平状态，第一壳体110和第二壳体120之间的夹角为α。此时，转动机构130处于展平状态。
第一壳体110设有第一凹槽1101和第二凹槽1102，第二凹槽1102环绕第一凹槽1101设置。第一凹槽1101和第二凹槽1102的开口均位于第一壳体110的顶面。第一凹槽1101和第二凹槽1102均自第一壳体110的顶面向底面的方向凹陷。其中，第二凹槽1102位于第一壳体110远离转动机构130的位置。示例性的，第二凹槽1102呈“匚”字型。
第二壳体120和第一壳体110的结构相同，且相对转动机构130镜像对称。第二壳体120设有第三凹槽1201和第四凹槽1202，第四凹槽1202环绕第三凹槽1201设置。第三凹槽1201和第四凹槽1202的开口均位于第二壳体120的顶面。第三凹槽1201和第四凹槽 1202均自第二壳体120的顶面向底面的方向凹陷。其中，第四凹槽1202位于第二壳体120远离转动机构130的位置。示例性的，第四凹槽1202呈“匚”字型。如图1至图3所示，第三凹槽1201和第一凹槽1101形成上文第一安装槽101，第四凹槽1202和第二凹槽1102形成上文第二安装槽102。
需要说明的是，本申请实施例描述可折叠终端1000时所采用“顶”和“底”等方位用词主要依据可折叠终端1000于附图2中的展示方位进行阐述，以朝向Z轴正方向为“顶”，以朝向Z轴负方向为“底”，其并不形成对可折叠终端1000于实际应用场景中的方位的限定。
请一并参阅图4，图4是图2所示可折叠终端1000在第一种实施例下显示屏200的结构示意图。
显示屏200安装于第一壳体110和第二壳体120。显示屏200包括第一显示部分210、第二显示部分220和可折叠部分230，可折叠部分230连接于第一显示部分210和第二显示部分220之间。具体的，第一显示部分210安装于第一壳体110，第二显示部分220安装于第二壳体120，可折叠部分230与转动机构130相对设置。其中，可折叠部分230可沿X轴方向发生弯折。
应当理解的是，可折叠部分230与转动机构130相对设置，是指，可折叠部分230在可折叠装置100上的投影至少部分覆盖转动机构130，或者，转动机构130在显示屏200上的投影至少部分覆盖可折叠部分230。
如图1所示，可折叠终端1000处于折叠状态时，第一显示部分210和第二显示部分220相对设置，可折叠部分230发生弯折。此时，显示屏200处于折叠状态，显示屏200的外露面积比较少，可大大降低显示屏200被损坏的概率，实现对显示屏200的有效保护。如图2所示，可折叠终端1000处于展开状态时，第一显示部分210和第二显示部分220相对展开，可折叠部分230不发生弯折而展平。此时，第一显示部分210、第二显示部分220和可折叠部分230两两之间的夹角均为α，显示屏200具有大面积的显示区域，实现可折叠终端1000的大屏显示，提高用户的使用体验。
应当理解的是，本申请实施例所示可折叠终端1000采用向内折叠的方式进行折叠，可折叠终端1000处于折叠状态时，显示屏200位于可折叠装置100的内侧。在其他一些实施例中，可折叠终端1000也可以采用向外折叠的方式进行折叠，可折叠终端1000处于折叠状态时，显示屏200位于可折叠装置100的外侧。

需要说明的是，本申请实施例所提及的“A层叠于B”，是指A至少部分覆盖B，此时，A与B之间可以直接接触，也可以间接接触。比如，上文所描述的“保护贴膜250层叠于显 示面241”，是指保护贴膜250在显示面241所在平面的投影的至少部分位于显示面241。此时，保护贴膜250也可以与显示面241直接接触，保护贴膜250也可以通过其他膜层结构与显示面241间接接触，即保护贴膜250与显示面241之间也可存在其他膜层结构，后文中有关“层叠”的描述可做相同理解。
显示面板240包括第一部分244、第二部分245和第三部分246，第三部分246连接于第一部分244和第二部分245之间。保护贴膜250包括第一保护部分251、第二保护部分252和第三保护部分253，第三保护部分253连接于第一保护部分251和第二保护部分252之间。第一保护部分251贴合于第一部分244，且与第一部分244形成第一显示部分210。第二保护部分贴合252于第二部分245，且与第二部分245形成第二显示部分220。第三保护部分253贴合于第三部分246，且与第三部分246形成可折叠部分230。
请一并参阅图6，图6是图2所示可折叠终端1000在第一种实施例下的平面结构示意图。
装饰件300安装于第一壳体110和第二壳体120，且环绕显示面板240设置。本实施例中，装饰件300还环绕保护贴膜250设置，且与保护贴膜250间隔设置。即，保护贴膜250位于装饰件300的内侧，且与装饰件300间隔设置，也即，保护贴膜250相对于装饰件300内缩，以在可折叠终端1000的整机组装完成后，便于将保护贴膜250贴合于显示面板240。其中，装饰件300的内边缘与保护贴膜250的边缘之间的距离为w 1。即，保护贴膜250相对装饰件300的内边缘内缩w 1。示例性的，w 1在0.5mm～1mm之间。
需要说明的是，本申请实施例描述可折叠终端1000时所采用“内”和“外”等方位用词主要依据可折叠终端1000于附图2中的展示方位进行阐述，以靠近可折叠终端1000的中心为“内”，以远离可折叠终端1000的中心为“外”，其并不形成对可折叠终端1000于实际应用场景中的方位的限定。
装饰件300包括第一子装饰件310和第二子装饰件320。第一子装饰件310安装于第一壳体110，且环绕第一部分244设置。第二子装饰件320安装于第二壳体120，且环绕第二部分245设置。具体的，第一子装饰件310安装于第二凹槽1102，第二子装饰件320安装于第四凹槽1202。示例性的，第一子装饰件310和第二子装饰件320均呈“匚”字型，且关于转动机构130镜像对称。

第二子装饰件320与第一子装饰件310的结构相同。第二子装饰件320包括第二安装部322和第二装饰部321，第二装饰部321固定连接于第二安装部322的顶部。示例性的，第二子装饰件320的横截面呈“T”字型。具体的，第二安装部322安装于第四凹槽1202， 第二装饰部321凸出于第四凹槽1202，且遮盖第二部分245的边缘和第二壳体120的边缘，以在可折叠终端1000折叠和展开过程中，遮挡第二显示部分220的边缘和第二壳体120的边缘之间的间隙，保证可折叠终端1000的外观一致性。其中，第二装饰部321遮盖非显示区域243的边缘，以避免第二装饰部321影响显示区域342的正常显示。此时，保护贴膜250的边缘与第二子装饰件320中第二装饰部321的内边缘之间的距离为w 1。
需要说明的是，显示面板240采用多层结构层叠而成，可折叠终端1000在折叠状态和展开状态之间切换的过程中，多层结构之间会沿垂直于折叠轴线的方向(图示Z轴方向)发生相互错动，导致显示面板240中第一部分244的边缘与第一壳体110之间的间隙、以及显示面板240中第二部分245的边缘与第二壳体120之间的间隙处于变化状态，间隙时大时小，第一子装饰件310遮盖了第一部分244的边缘与第一壳体110的边缘，以遮盖第一部分244与第一壳体110之间的间隙，第二子装饰件320遮盖第二部分245的边缘与第二壳体110的边缘，以遮盖第二部分245与第二壳体120之间的间隙，保证了可折叠终端1000的外观一致性，提高了可折叠终端1000的外观美观度。
防尘件400粘接于装饰件300，且在装饰件300的作用下被压缩而抵接于显示面板240。具体的，防尘件400位于第一子装饰件310与显示面板240之间，还位于第二子装饰件320与显示面板240之间。其中，防尘件400的厚度为d。示例性的，防尘件400可为背胶、泡棉或软件等。

本实施例中，第一盖板层31包括第一柔性结构层33和柔性胶层34，第二盖板层32包括第二柔性结构层35。柔性胶层34连接于第一柔性结构层33和第二柔性结构层35之间。第一柔性结构层33的面积小于第二柔性结构层35的面积。柔性胶层34的面积小于或等于第一柔性结构层33的面积。
示例性的，第一柔性结构层33和第二柔性结构层35可采用透明聚酰亚胺(CPI)、聚对苯二甲酸乙二醇酯(PET，polyethylene glycol terephthalate)、热塑性聚氨酯弹性体(TPU)或超薄玻璃(UTG，ultra thin glass)等模量和硬度较高的材料制成，柔性胶层34可采用光学胶(OCA，optically clear adhesive)等模量和硬度较低的材料制成。其中，第一柔性结构层33和第二柔性结构层35的材料可以相同，也可以不同。
在其他一些实施例中，第一盖板层31也可以包括多层第一柔性结构层33和多层柔性胶层34，一层柔性胶层34连接于第一柔性结构层33和第二柔性结构层35之间，其余柔性胶层34连接于相邻两层第一柔性结构层33之间，和/或，第二盖板层32包括多层第二柔性结构层35和多层柔性粘接层(图未示)，每一层柔性粘接层连接于相邻两层第二柔性结构层35之间，本申请对此不作具体限定。
保护贴膜250的面积小于第一盖板层31的面积。具体的，保护贴膜250层叠于第一盖板层31的顶面。其中，保护贴膜250层叠于第一盖板层31的顶面的中间区域。此时，第一盖板层31的周侧面位于保护贴膜250的周侧面的外侧。本实施例中，保护贴膜250和第一盖板层31均位于装饰件300的内侧，第二盖板层32、显示功能层20和支撑层10均位于装饰件300的底侧。具体的，保护贴膜250和第一盖板层31均位于第一装饰部311和第二装饰部321之间，第二盖板层32、显示功能层20和支撑层10均位于第一装饰部311和第二装饰部321的底侧。
应当理解的是，第一盖板层31的周侧面，是指第一盖板层31中连接于第一盖板层31的顶面和第一盖板层31的底面之间的表面。后文中有关“周侧面”的描述可做相同理解。
此外，防尘件400位于第二区域322与装饰件300之间。同样的，防尘件400也位于边缘区域248与装饰件300之间。示例性的，防尘件400可粘接于装饰件300，且在装饰件300的作用下被压缩而抵接于第二区域322。其中，第一子防尘件410位于第二盖板层32与第一装饰部311之间，第二子防尘件420位于第二盖板层32与第二装饰部321之间。此时，第二盖板层32位于防尘件400和显示功能层20之间，第二盖板层32可保护显示功能层20，不仅可防止防尘件400磨损显示功能层20，还可以避免装饰件300对显示功能层20的刮擦，保证可折叠终端1000的使用可靠性。
本实施例中，第一盖板层31位于装饰件300的内侧，防尘件400位于第二盖板层32与装饰件300之间，使得第一盖板层31沿Z轴方向上共用防尘件400和装饰件300的厚度空间，不仅可以减小可折叠终端1000的厚度，而且在可折叠终端1000处于折叠状态时，还可以减小显示面板240的第一部分244与第二部分245之间的距离D，进而减小处于折叠状态的可折叠终端1000的厚度，有利于实现可折叠终端1000的轻薄化设计。
请参阅图9至图11，图9是图2所示可折叠终端1000在第二种实施例下的平面结构示意图，图10是图1所示可折叠终端1000在第二种实施例下沿I-I处剖开的局部剖面结构示意图，图11是图2所示可折叠终端1000在第二种实施例下沿II-II处剖开的局部剖面结构示意图。
本实施例所示可折叠终端1000与上述第一种实施例所示可折叠终端1000的不同之处在于，可折叠终端1000处于折叠状态时(如图10所示)，第一盖板层31的周侧面位于保护贴膜250的周侧面的内侧，即，第一盖板层31相对保护贴膜250内缩。第一盖板层31 的周侧面与保护贴膜250的周侧面之间的距离为w 3。示例性的，w 3在0.2mm～1mm之间。其中，第一柔性结构层33的周侧面和柔性胶层34的周侧面均位于保护贴膜250的周侧面的内侧，柔性胶层34的周侧面还位于第一柔性结构层33的周侧面的内侧。
可折叠终端1000处于展开状态时(如图9和图11所示)，第一盖板层31的周侧面与保护贴膜250的周侧面齐平。此时，w 2＝w 1。其中，第一柔性结构层33的周侧面和柔性胶层34的周侧面均与保护贴膜250的周侧面齐平。应当理解的是，第一盖板层31的周侧面与保护贴膜250的周侧面齐平，是指第一盖板层31的周侧面与保护贴膜250的周侧面基本齐平。此时，第一盖板层31的周侧面与保护贴膜250的周侧面之间的距离在加工误差之内。示例性的，加工误差为±0.2mm。
需要说明的是，在可折叠终端1000的组装过程中，第一盖板层31可与保护贴膜250采用一体裁切工艺，最后随保护贴膜250一起加工成型并贴附于第二盖板层32上，以提高第一盖板层31的周侧面与保护贴膜250的周侧面的对齐程度。
上述第一种实施例所示的可折叠终端1000处于展开状态时，使用者会看到保护贴膜250的周侧面和第一盖板层31的周侧面，即显示屏200上会看到两圈外形。而本实施例所述可折叠终端1000处于展开状态时，由于第一盖板层31的周侧面与保护贴膜250的周侧面齐平，显示屏200上仅看到保护贴膜250的周侧面，即显示屏200上仅看到一圈外形，提高了可折叠终端1000的外观精致度。
请参阅图12和图13，图12是图1所示可折叠终端1000在第三种实施例下沿I-I处剖开的局部剖面结构示意图，图13是图2所示可折叠终端1000在第三种实施例下沿II-II处剖开的局部剖面结构示意图。
本实施例所示可折叠终端1000与上述第一种实施例所示可折叠终端1000的不同之处在于，可折叠终端1000处于折叠状态时(如图12所示)，第一盖板层31的周侧面位于保护贴膜250的周侧面的内侧，即，第一盖板层31相对保护贴膜250内缩。其中，第一柔性结构层33的周侧面和柔性胶层34的周侧面均位于保护贴膜250的周侧面的内侧，柔性胶层34的周侧面还位于第一柔性结构层33的周侧面的内侧。
可折叠终端1000处于展开状态时(如图13所示)，第一盖板层31的周侧面位于保护贴膜250的周侧面的内侧，即，第一盖板层31仍相对保护贴膜250内缩。其中，第一柔性结构层33的周侧面和柔性胶层34的周侧面均位于保护贴膜250的周侧面的内侧，柔性胶层34的周侧面与第一柔性结构层33的周侧面齐平。在其他一些实施例中，柔性胶层34的周侧面也可位于第一柔性结构层33的周侧面的内侧。
本实施例中，显示屏200还包括遮挡层260，遮挡层260位于保护贴膜250的底面的边缘。其中，遮挡层260可采用不透光材料制成。比如，遮挡层260可为黑色油墨层，或者，遮挡层260可为通过丝印工艺形成的黑色丝印。可折叠终端1000处于折叠状态或展开状态时，遮挡层260可遮挡第一盖板层31的周侧面。其中，遮挡层260的宽度为w 4。示例性的，w 4在0.2mm～1mm之间。
应当理解的是，保护贴膜250的底面的边缘，是指保护贴膜250的底面中靠近保护贴膜250的周侧面的区域。后文中有关“边缘”的描述可做相同理解。
本实施例所述可折叠终端1000处于展开状态时，第一盖板层31的周侧面位于保护贴 膜250的周侧面的内侧，遮挡层260遮挡了第一盖板层31的周侧面，显示屏200上仅看到保护贴膜250的周侧面，即显示屏200上仅看到一圈外形，改善了显示屏200的视觉效果，提高了可折叠终端1000的外观精致度。
在其他一些实施例中，保护贴膜250可包括多层贴膜层(图未示)和一层或多层胶层(图未示)，任一胶层均连接于相邻两个贴膜层之间。此时，遮挡层260可位于一层贴膜层的底面的边缘。同样的，在可折叠终端1000处于展开状态时，遮挡层260可遮挡第一盖板层31的周侧面，提高可折叠终端1000的外观精致度。此外，胶层的面积可小于贴膜层的面积，即胶层可相对贴膜层内缩。此时，胶层的周侧面位于贴膜层的周侧面的内侧。当贴膜层与胶层发生相互错动时，遮挡层260还可以遮挡胶层错动后的残留痕迹，可进一步提高可折叠终端1000的外观精致度。
请参阅图14和图15，图14是图1所示可折叠终端1000在第四种实施例下沿I-I处剖开的局部剖面结构示意图，图15是图2所示可折叠终端1000在第四种实施例下沿II-II处剖开的局部剖面结构示意图。
本实施例所示可折叠终端1000与上述第一种实施例所示可折叠终端1000的不同之处在于，第一盖板层31的顶面包括第三区域311和第四区域312，第四区域312环绕第三区域311设置。示例性的，可折叠终端1000处于展开状态时，第三区域311和第四区域312之间以装饰件300的内表面为分界线进行划分。具体的，第三区域311位于装饰件300的内侧，第四区域312位于装饰件300的底侧，即装饰件300遮盖第四区域312。其中，第三区域311与中心区域247相对应，第四区域312与边缘区域248相对应。此时，保护贴膜250层叠于第三区域311。
本实施例中，保护贴膜250位于装饰件300的内侧，第一盖板层31、第二盖板层32、显示功能层20和支撑层10均位于装饰件300的底侧。具体的，保护贴膜250位于第一装饰部311和第二装饰部321之间，第一盖板层31、第二盖板层32、显示功能层20和支撑层10均位于第一装饰部311和第二装饰部321的底侧。
此外，装饰件300设有避让空间301，避让空间301与第四区域312相对设置，用于避让第一盖板层31的第四区域312，以防止第一盖板层31与装饰件300发生干涉。具体的，第一子装饰件310设有第一避让空间313。其中，第一避让空间313设于第一装饰部311。示例性的，第一避让空间313呈缺口状。第一避让空间313位于第一装饰部311朝向保护贴膜250的一侧，且与第一子防尘件410间隔设置。第一避让空间313的开口位于第一装饰部311的底面。第一避让空间313自第一装饰部311的底面向顶面的方向凹陷，且贯穿第一装饰部311朝向保护贴膜250的表面。
第二子装饰件320设有第二避让空间323，第二避让空间323与第一避让空间313围合形成避让空间301。其中，第二避让空间323设于第二装饰部321。示例性的，第二避让空间323呈缺口状。第二避让空间323位于第二装饰部321朝向保护贴膜250的一侧，且与第二子防尘件420间隔设置。第二避让空间323的开口位于第二装饰部321的底面。第二避让空间323自第二装饰部321的底面向顶面的方向凹陷，且贯穿第二装饰部321朝向保护贴膜250的表面。
可折叠终端1000处于折叠状态和展开状态时，第四区域312在装饰件300上的投影， 部分位于第一避让空间313内，部分位于第二避让空间323内。此时，第一盖板层31可与防尘件400和装饰件300共用沿Z轴方向上的厚度空间，有利于实现可折叠终端1000的轻薄化设计。此外，可折叠终端1000处于折叠状态时，由于装饰件300遮挡第四区域312，显示屏200上仅看到保护贴膜250的边缘，即显示屏200上仅看到一圈外形，改善了显示屏200的视觉效果，提高了可折叠终端1000的外观精致度。
