技术领域
本申请涉及终端技术领域，尤其涉及一种支撑组件及终端设备。
背景技术
随着手机的不断发展，可折叠手机也逐渐出现在人们的生活中，可折叠手机可以实现屏幕的展开和折叠，展开时可以实现更大的屏幕，折叠时更加便于携带。通常可折叠手机包含有折叠组件、支撑片和柔性屏，其中，支撑片位于折叠组件和柔性屏之间，为柔性屏提供支撑。通过折叠组件的折叠和展开运动带动柔性屏，能够实现可折叠手机的折叠和展开功能。
但是可折叠手机在折叠和展开的过程中，经常会产生异常噪声。
发明内容
为了解决上述技术问题，本申请提供一种支撑组件及终端设备，能够降低可折叠终端设备在折叠和展开过程中所产生的异常噪声。
本申请提供一种支撑组件，包括：支撑件，支撑件具有相对的第一侧面和第二侧面、以及连接于第一侧面和第二侧面之间的第一端面，第一侧面至少具有第一可弯折区，第一可弯折区与第一端面连接，在第一端面上设有槽；粘接结构，粘接结构的至少部分位于第一侧面和第二侧面上。
这样，当支撑组件应用于终端设备中时，支撑组件随着柔性屏的弯折而弯折的过程中，槽可将第一端面隔断为多个部分，各部分的尺寸均小于第一端面的尺寸，因此，在可折叠手机折叠或展开的过程中，各部分更容易产生变形，从而能够降低支撑件上波峰和波谷之间的应力差，进而降低支撑件弯折过程中产生的异常噪音。
在一些可能实现的方式中，支撑件还包括与第一端面相对的第二端面，第二端面为固定端面，第一端面为自由端面。这样，第二端面即为靠近柔性屏的中心的端面，自由端面上所设置的槽，能够更好地吸收支撑件上的应力，从而降低支撑件波峰和波谷之间的应力差，进而减小因应力差产生的异常噪声。
在一些可能实现的方式中，槽沿第一方向的尺寸与第一可弯折区沿第一方向的尺寸的比值范围为：0.35-0.65，第一方向为槽的深度方向。槽的深度方向为从第一端面至第二端面的方向。这样，可减少支撑件在弯折过程中的应力峰值，从而减小支撑件在弯折过程中波峰和波谷之间的应力差，进而降低因应力差产生的异常噪声。
在一些可能实现的方式中，槽沿第一方向的尺寸与弯折区沿第一方向的尺寸之间的比值为0.5。这样，可减少支撑件在弯折过程中的应力峰值，从而减小支撑件在弯折过程中波峰和波谷之间的应力差，从而降低因应力差产生的异常噪声。
在一些可能实现的方式中，槽的数量为多个。这样，可将支撑件的第一端面隔断为多个部分，各个部分的尺寸更小，因此，在终端设备折叠或展开的过程中，各部分更容易产生变形，从而能够降低支撑件上波峰和波谷之间的应力差，进而降低支撑件弯折过程中产生的异常噪音。
在一些可能实现的方式中，粘接结构包括设于第一侧面上的第一背胶结构以及设于第二侧面上的第二背胶结构。这样，当支撑组件应用于终端设备时，可通过第一背胶结构与柔性屏粘接，通过第二背胶结构与折叠组件粘接，因此，可提高支撑组件与柔性屏和折叠组件的粘接强度。
在一些可能实现的方式中，粘接结构还包括：点胶结构，点胶结构的至少部分设于第一侧面和/或第二侧面上。这样，可通过第一背胶结构和点胶结构与柔性屏粘接，和/或可通过第二背胶结构和点胶结构与折叠组件粘接，因此，可以进一步提高支撑组件与柔性屏和/或折叠组件之间的粘接强度。
在一些可能实现的方式中，支撑组件还包括：第一垫片，第一垫片位于第一侧面上；和/或，第二垫片，第二垫片位于第二侧面上。由于点胶结构通常为具有粘性的胶状液体凝固而成，而第一垫片具有一定的厚度，这样，在制作终端设备时，在向第一侧面注入胶状液体后，第一侧面与柔性屏之间能够很好地容纳胶状液体，从而使得形成的点胶结构的粘接强度较高。
在一些可能实现的方式中，第一侧面还具有与第一可弯折区邻接的第一非弯折区，第一背胶结构在第一侧面的投影位于第一非弯折区内。第一非弯折区可以指在终端设备折叠的过程中，始终处于非弯折状态的区域，这样，第一背胶结构不易与柔性屏发生脱粘以及粘接的情况，从而也能够尽可能减少因反复脱粘以及粘接而产生的异常噪声。
在一些可能实现的方式中，第二侧面具有相邻接的第二可弯折区和第二非弯折区，第二背胶结构在第二侧面的部分投影位于第二非弯折区内，第二背胶结构在第二侧面的其他部分投影位于第二可弯折区内。这样，第二背胶结构具有较大的粘接面积，从而能够提高支撑件与折叠组件之间的粘接强度。
在一些可能实现的方式中，第二侧面具有第二非弯折区，第二背胶结构在第二侧面的投影位于第二非弯折区内。这样，在终端设备折叠的过程中，第二背胶结构始终处于非弯折状态的区域，这样，第二背胶结构不易与折叠组件发生脱粘以及粘接的情况，从而也能够尽可能减少因反复脱粘以及粘接而产生的异常噪声。
在一些可能实现的方式中，第一背胶结构的边缘与第一垫片的边缘之间具有间隙；或者，第一背胶结构与第一垫片相接触。这样，在制作终端设备的过程中，在向支撑件上注入胶状液体时，胶状液体可流动至第一背胶结构与第一垫片之间的间隙中，由此可增加点胶结构的粘接面积，从而增加点胶结构的粘接强度。
在一些可能实现的方式中，第一背胶结构上设有用于容纳点胶结构的第一点胶槽。由于第一背胶结构具有一定的厚度，因此，第一点胶槽能够很好地容纳胶状液体，从而能够提高点胶结构的粘接强度。
在一些可能实现的方式中，第一点胶槽设于第一背胶结构朝向第一垫片的边缘。当第一背胶结构与第一垫片之间具有间隙时，在第一点胶槽内注入胶状液体时，胶状液体也会流动至间隙中，这样，能够增加胶状液体凝固后形成的点胶结构的粘接面积，从而提高粘接强度。当第一背胶结构与第一垫片相接触时，第一垫片可与第一背胶结构将第一点胶槽围成封闭的形状，这样，第一点胶槽也能够很好地容纳胶状液体。
在一些可能实现的方式中，第一垫片上设有用于容纳点胶结构的第二点胶槽。由于第一垫片具有一定的厚度，因此，第二点胶槽能够很好地容纳胶状液体，从而能够提高点胶结构的粘接强度。
在一些可能实现的方式中，第二点胶槽设于第一垫片朝向第一背胶结构的边缘。当第一背胶结构与第一垫片之间具有间隙时，在第二点胶槽内注入胶状液体时，胶状液体也会流动至间隙中，这样，能够增加胶状液体凝固后形成的点胶结构的粘接面积，从而提高粘接强度。当第一背胶结构与第一垫片相接触时，第一垫片可与第一背胶结构将第二点胶槽围成封闭的形状，这样，第二点胶槽也能够很好地容纳胶状液体。
在一些可能实现的方式中，第一点胶槽与第二点胶槽连通；或者，第二点胶槽的槽口封闭。当第一点胶槽与第二点胶槽连通时，第一点胶槽和第二点胶槽可围成容纳空间，以很好地容纳点胶结构。当第二点胶槽的槽口封闭时，则第二点胶槽能够很好地容纳点胶结构。因此，本申请能够提高点胶结构的粘接强度。
在一些可能实现的方式中，支撑件上设有用于容纳点胶结构的第三点胶槽。这样，支撑件还可通过点胶结构与柔性屏或折叠组件粘接。
在一些可能实现的方式中，第三点胶槽从第一侧面贯穿至第二侧面。这样，支撑件还可以通过点胶结构与柔性屏和折叠组件粘接。
在一些可能实现的方式中，第二背胶结构上设有用于容纳点胶结构的第四点胶槽。这样，支撑件还可通过第四点胶槽内的点胶结构与折叠组件粘接，因此，能够提高支撑件与折叠组件之间的粘接强度。
在一些可能实现的方式中，第一点胶槽、第二点胶槽、第三点胶槽和第四点胶槽之间的位置关系，满足以下特征中的至少一种：第一点胶槽与第三点胶槽连通；第二点胶槽与第三点胶槽连通；第四点胶槽与第三点胶槽连通。这样，在制作终端设备时，可向第四点胶槽注入胶状液体，胶状液体可流动至第三点胶槽、第一点胶槽和第二点胶槽，因此，制作工艺简单。此外，容纳至第一点胶槽、第二点胶槽、第三点胶槽和第四点胶槽的点胶结构能够对柔性屏、第一背胶结构、支撑件、第二背胶结构和折叠组件起到很好的粘接作用。
在一些可能实现的方式中，第二背胶结构的边缘设有与第四点胶槽连通的开口。这样，在制作终端设备时，可向开口注入胶状液体，胶状液体可从开口处流动至第四点胶槽，由于开口位于第二背胶结构的边缘，因此，工艺简单、操作方便。
在一些可能实现的方式中，支撑件的材料包括钛合金或钛铜合金。由于钛合金和钛铜合金的弹性模量较低，低弹性模量的支撑件更容易弯曲而不易产生异常噪声。因此，可降低支撑件弯折过程中波峰和波谷的应力差，进而降低在弯折过程中产生的异常噪声。此外，由于钛合金和钛铜合金的密度较小，因此，还能够降低支撑件的重量，进而可实现整机减重效果。
本申请还提供一种终端设备，包括至少上述任一项的支撑组件，多个支撑组件中至少存在两个支撑组件的第一端面相对设置。终端设备能够实现上述支撑组件的所有效果。
在一些可能实现的方式中，第一端面相对设置的两个支撑组件中，其中一个支撑组件上的槽与另一个支撑组件上的槽位置错开。在支撑组件为柔性屏提供支撑时，位置错开的槽能够减少柔性屏中较大长度区域出现悬空的情况，因此能够提高柔性屏的使用寿命。
在一些可能实现的方式中，终端设备还包括折叠组件和柔性屏，支撑组件位于折叠组件和柔性屏之间，第一侧面或第二侧面朝向柔性屏，柔性屏具有相对的第三非弯折区和第四非弯折区以及位于第三非弯折区和第四非弯折区之间的第三可弯折区，支撑组件的第一可弯折区在柔性屏的投影位于第三可弯折区内，支撑组件的第一非弯折区在柔性屏的投影位于第三非弯折区或第四非弯折区内。终端设备能够实现上述支撑组件的所有效果。

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，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

本申请实施例的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一目标对象和第二目标对象等是用于区别不同的目标对象，而不是用于描述目标对象的特定顺序。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中，除非另有说明，“多个”的含义是指两个或两个以上。例如，多个处理单元是指两个或两个以上的处理单元；多个系统是指两个或两个以上 的系统。
本申请实施例提供一种支撑组件，支撑组件可应用于可折叠手机。支撑组件30还可以应用于其他具有折叠功能的终端设备，例如，可折叠平板电脑、可折叠游戏机、可折叠个人数字助理(personal digital assistant，PDA)等。
如图1a和图1b所示，可折叠手机至少包括折叠组件10以及固定于折叠组件10一侧面的柔性屏20，折叠组件10能够折叠或展开，以带动柔性屏20折叠或展开。可折叠手机可以为内折折叠手机，即，柔性屏20位于折叠组件10的内侧；可折叠手机也可以为外折折叠手机，即，柔性屏20位于折叠组件10的外侧。当可折叠手机为内折折叠手机时，当折叠组件10的折叠角度为0时，柔性屏20完全包裹在折叠组件10的内部，既可以减小可折叠手机的尺寸，又可以对柔性屏20起到保护的作用；当折叠组件10完全展开时，即，折叠组件10的角度为180°，柔性屏20处于展平态，也处于最大显示面积的状态，此时用户可以在柔性屏20上进行操作。
如图2a所示，可折叠手机还包括固定于折叠组件10和柔性屏20之间的支撑组件30。从图2a中可以看出，折叠组件10需要实现柔性屏20的折叠和展开，其本身具有复杂的结构，因此，在折叠组件10朝向柔性屏20的一面可能存在缝隙、凸起、凹槽和组装孔等结构，也就是说，朝向柔性屏20的一面可能存在凸起或凹陷，尤其是实现折叠组件10弯折的运动区域11，存在较多的凸起或凹陷。当可折叠手机处于展平态时，折叠组件10上的这些结构会影响柔性屏20的平整度，用户手指在柔性屏20上触控或划过时会有凹凸不平感，同时也会降低柔性屏20的使用寿命。因此，位于柔性屏20和折叠组件10之间，且能够为柔性屏20提供支撑的支撑组件30便显得尤为重要。
在本申请一种实施例中，如图2a所示，支撑组件30包括相对的两个支撑件31和多个背胶结构36，多个背胶结构36分别设置在支撑件31与柔性屏20之间以及支撑件31与折叠组件10之间，背胶结构36能够对柔性屏20、支撑件31以及折叠组件10进行粘接。其中，支撑件31为金属薄片，金属薄片覆盖折叠组件10上凹凸不平的运动区域11以及折叠组件10上除运动区域11之外的部分非运动区域12。
为了保证柔性屏20与折叠组件10之间的粘接强度，背胶结构36的宽度应满足预定的宽度要求，如图2b所示，背胶结构36的部分会覆盖至柔性屏20的非弯折区域22，其他部分覆盖至柔性屏20的弯折区域21。其中弯折区域21指的是，当可折叠手机折叠时，柔性屏20的外表面为弧面的区域。由于在可折叠手机折叠或展开的过程中，弯折区域21的曲率在时刻发生变化，柔性屏20的弯折区域21上远离其中心的位置，与柔性屏20的中心之间的距离在时刻发生变化，背胶结构36与柔性屏20之间不断受到剪切力，因此，覆盖至弯折区域21的背胶结构36可能会受到柔性屏20的拉扯而脱粘。当可折叠手机折叠或展开至一定角度后停止时，背胶结构36与柔性屏20重新粘接在一起。而可折叠手机折叠或展开的频率较高，因此，覆盖至弯折区域21的背胶结构36与柔性屏20反复粘接及脱粘，进而产生异常噪声。
此外，如图3所示，支撑件31的材料为SUS301不锈钢。支撑件31的边缘均为直线。如图2a所示，在可折叠手机折叠或展开的过程中，折叠组件10的运动区域11以及柔性屏20的弯折区域21均会产生弯折，支撑件31也会产生弯折。金属薄片的 厚度通常很小，因此，如图4a和图4b所示，支撑件31在弯折的过程中其表面并不是一个平滑的曲面，而是呈现一种高低起伏的波浪状态的曲面。在弯折过程中，弯折弧面上的波峰和波谷所受应力不均，产生应力差(可称为弯折应力)；在弯折停止后，弯折应力释放，金属薄片会由于应力差而产生振动，从而产生异常噪声。
基于此，如图5所示，在本申请另一实施例中，可折叠手机包括折叠组件10、固定于折叠组件10一侧面的柔性屏20、以及固定于折叠组件10和柔性屏20之间的支撑组件30。
如图6所示，支撑组件30包括两个相对的支撑件31、上背胶结构32、下背胶结构35、点胶结构33(图6中未示出)和垫片34。如图5所示，支撑件31的远离柔性屏20中心的部分区域通过上背胶结构32和点胶结构33与柔性屏20粘接。支撑件31的远离柔性屏20中心的部分区域通过下背胶结构35和点胶结构33与折叠组件10粘接。
如图5所示，支撑件31靠近柔性屏20中心的一端为自由端314，两个支撑件31的自由端314相对，且两个支撑件31的自由端314之间具有间隙，以适应可折叠手机折叠或展开的过程中，弯折区域21曲率的变化。
如图6所示，支撑件31通常为金属薄片，且具有两个长边缘和两个短边缘，其中一个长边缘为自由端314。在支撑件31的自由端314上设置有卸力槽311。这样，卸力槽311可将自由端314隔断成多个部分，各部分沿支撑件31长边缘方向的尺寸比支撑件31的长边缘尺寸小，因此，在可折叠手机折叠或展开的过程中，各部分更容易产生变形，从而能够降低支撑件31上波峰与波谷之间的应力差，进而降低支撑件31弯折过程中产生的异常噪音。
在本实施例中，如图6所示，卸力槽311的数量可以为一个，一个卸力槽311可设置在支撑件31的靠近中部的位置。在本申请的其他实施例中，卸力槽311的数量为多个，多个卸力槽311沿支撑件31的自由端314均匀设置，这样可起到更好地降噪作用。
如图7a和图7b所示，支撑组件30的两个支撑件31上的卸力槽311位置错开。若两个支撑件31上的卸力槽311位置相对应，当可折叠手机处于展平态时，柔性屏20在卸力槽311的位置将失去支撑而悬空，且失去支撑的区域的长度大于两个卸力槽311的长度之和，这样，容易出现因柔性屏20的较长长度区域悬空而出现裂纹的情况。因此，支撑组件30的两个支撑件31上的卸力槽311位置错开，能够在一定程度上提高柔性屏20的使用寿命。
需要说明的是，图7a为支撑组件30在第一视角下，弯折第一角度时的结构示意图，图7b为图7a中的支撑组件30在第二视角下，弯折第一角度时的结构示意图，其中第一视角的方向与第二视角的方向相反，也就是说，图7b是从图7a的背面朝向图7a的正面投影后旋转180°获得的视图。从图7a中可以看出支撑件31与柔性屏20之间的粘接结构，从图7b中可以看出支撑件31与折叠组件10之间的粘接结构。
如图7a所示，假定支撑件31的总宽度为D1，支撑件31固定上背胶结构32的区域宽度为D2，支撑件31上固定上背胶结构32的一面上，未固定上背胶结构32的区域(非背胶区域)宽度为D3，则D1＝D2+D3。
本实施例中，对支撑件31进行有限元分析，其中卸力槽311的深度分别为支撑件31其余区域宽度的四分之一、二分之一和四分之三，分析结果分别参照图9a、图9b和图9c。从图9a-图9c中可以看出，当卸力槽311的深度为支撑件31非背胶区域宽度D3的四分之一时，支撑件31的最大应力为748.6Mpa；当卸力槽311的深度为支撑件31非背胶区域宽度D3的二分之一时，支撑件31的最大应力为563.7Mpa；当卸力槽311的深度为支撑件31非背胶区域宽度D3的四分之三时，支撑件31的最大应力为633.2Mpa。因此，卸力槽311深度为支撑件31非背胶区域宽度的二分之一，支撑件31的应力峰值最小，当卸力槽311深度更大或更小时，应力峰值均更大，则波峰和波谷之间的应力也更大，弯折过程中异常噪声也更大。因此，可将卸力槽311的深度设为支撑件31的非背胶区域宽度D3的二分之一，这样，能够使得可折叠手机在折叠或展开的过程中，支撑件31上产生的峰值应力较小，从而能够减小波峰和波谷的应力差，进而能够减少因较大应力产生的异常噪声。
需要说明的是，支撑件31的背胶区域可以为支撑件31朝向柔性屏20的一面上，始终保持平面的区域，支撑件31的非背胶区域可以支撑件31朝向柔性屏20的一面上，随折叠组件10的弯折而弯折的区域。
在本申请的其他实施例中，卸力槽311的深度可设置为支撑件31的非背胶区域宽度D3的35％-65％，参照图9a-图9c中对支撑件31进行有限元分析的分析结果可知，卸力槽311的深度接近支撑件31的非背胶区域宽度D3的二分之一时，其应力较小，因此，将卸力槽311的深度设置为支撑件31的非背胶区域宽度D3的35％-65％，在可折叠手机折叠或展开的过程中，支撑件31上所产生的应力差较小，进而能够减少因应力差造成的异常噪声。
此外，从图5中可以看出，折叠组件10朝向柔性屏20的一面设置有螺钉、凸起、凹槽等局部特征，因此，如图7a所示，在支撑件31上设置多个避让槽312，进行防剐蹭避让，能够降低可折叠手机在折叠或展开的过程中，支撑件31与折叠组件10发生碰撞产生的异常噪声，从而进一步减少可折叠手机的异常噪声。
如图7a所示，支撑件31上设置有六个支撑件点胶槽313，且六个支撑件点胶槽313以支撑件31的中心对称布置。也就是说，在支撑件31中心的两侧，均布置三个支撑件点胶槽313。三个支撑件点胶槽313的长度各不相同。
在本申请的其他实施例中，支撑件点胶槽313的数量可以小于六个或大于六个，当支撑件点胶槽313的数量为一个时，一个支撑件点胶槽313设置在沿支撑件31的长度方向上的中部。
如图8所示，支撑件点胶槽313的部分在柔性屏20上的投影位于弯折区域21内，支撑件点胶槽313的其他部分在柔性屏20上的投影，位于柔性屏20上除弯折区域21以外的非弯折区域22。
支撑件31可采用低密度、低弹性模量金属，具体可采用TI合金(钛合金)或TI-Cu合金(钛铜合金)等。例如，TI合金TA4的弹性模量为116Gpa，图2a所示实施例中支撑件31的材料为SUS301不锈钢，其弹性模量为194Gpa。钛合金TA4的弹性模量比SUS301的弹性模量小，根据胡克定律，低弹性模量的金属薄片更容易弯曲而不易产生异常噪声。因此，支撑件31采用低弹性模量的金属，可降低金属薄片弯折过程 中波峰和波谷的应力差，进而降低在弯折过程中产生的异常噪声。此外，由于TI或TI-Cu合金等金属的密度较小，支撑件31采用TI合金或TI-Cu合金，还能够降低支撑件31的重量，进而可实现整机减重效果。
如图5所示，上背胶结构32固定于柔性屏20与支撑件31之间。上背胶结构32为长条状。上背胶结构32在柔性屏20上的投影，位于柔性屏20的非弯折区域22内，也就是说，上背胶结构32与弯折区域21无重叠。这样，在可折叠手机折叠或展开的过程中，上背胶结构32不易与柔性屏20发生脱粘以及粘接的情况，因此，也能够尽可能减少因反复脱粘以及粘接而产生的异常噪声。
如图7a所示，上背胶结构32具有朝向自由端314的背胶边缘322，在背胶边缘322上设置有上背胶豁口321，上背胶豁口321的数量与支撑件点胶槽313的数量相同，均为六个。且背胶豁口321在上背胶结构32的设置位置，与支撑件点胶槽313在支撑件31上的设置位置相对应。六个背胶豁口321与六个支撑件点胶槽313均一一对应连通，示例性的，六个背胶豁口321在支撑件31上的投影分别落入六个支撑件点胶槽313内。
如图5所示，下背胶结构35固定于支撑件31与折叠组件10之间。
如图6和图8所示，下背胶结构35与上背胶结构32不同。下背胶结构35也为长条状，下背胶结构35的宽度大于上背胶结构32的宽度。具体地，如图8所示，下背胶结构35在柔性屏20上的投影，既覆盖部分非弯折区域22，同时又覆盖部分弯折区域21，这样，下背胶结构35与折叠组件10之间的粘接强度能够满足使用要求。
如图7b所示，下背胶结构35上设置有下背胶点胶槽351，下背胶点胶槽351的数量与支撑件点胶槽313的数量相同，均为六个。下背胶点胶槽351与支撑件点胶槽313的设置位置对应。六个下背胶点胶槽351与六个支撑件点胶槽313均一一对应连通，示例性的，六个下背胶点胶槽351在支撑件31上的投影与多个支撑件点胶槽313均一一对应重合。
如图7b所示，在下背胶结构35的边缘上还朝内延伸设置有注入孔352，注入孔352设置在远离自由端314的一侧，注入孔352与下背胶点胶槽351连通。这样，在制作可折叠手机的过程中，在将折叠组件10、支撑件31、上背胶结构32和下背胶结构35组装在一起后，可以向注入孔352注入胶状液体，胶状液体可从注入孔352流动至下背胶点胶槽351，方便加工。
进一步地，如图7b所示，注入孔352的数量与下背胶点胶槽351的数量相同且位置一一对应，例如，注入孔352的数量也为六个。这样，在制作可折叠手机的过程中，可以向每个注入孔352注入胶状液体，胶状液体便可通过每个注入孔352流动至各下背胶点胶槽351，进而能够使得胶状液体均匀地分布在各下背胶点胶槽351内。
结合图8可知，支撑件31与柔性屏20之间的粘接结构包括上背胶结构32、点胶结构33和垫片34，且两者之间通过上背胶结构32和点胶结构33实现粘接。支撑件31与折叠组件10之间的粘接结构包括下背胶结构35和点胶结构33，且两者通过下背胶结构35和点胶结构33实现粘接。由于脱粘主要发生在柔性屏20与支撑件31之间，因此，在支撑件31与折叠组件10之间仅设置下背胶结构35和点胶结构33，而未设置垫片34以及点胶结构33，能够节省工艺流程，从而节省加工成本。
需要说明的是，上背胶结构32和下背胶结构35均可以为具有粘贴功能的结构，具体可以为胶带，例如，双面胶带、胶膜等。
如图5所示，垫片34设置在支撑件31与柔性屏20之间，且垫片34在支撑件31上的投影可覆盖部分支撑件31，垫片34在支撑件31上的投影与上背胶结构32在支撑件31上的投影无重叠。
如图7a所示，垫片34的垫片边缘341与上背胶结构32的背胶边缘322之间可具有间隙，垫片34上设置有垫片豁口342，垫片豁口342设置在垫片34靠近上背胶结构32的垫片边缘341，且垫片豁口342的数量与上背胶豁口321的数量相同，为六个。垫片豁口342在垫片34上的设置位置，与上背胶豁口321在上背胶结构32上的设置位置相对应。垫片豁口342、上背胶结构32上的上背胶豁口321以及垫片34与上背胶结构32之间的间隙可形成较大的容纳空间，支撑件点胶槽313位于容纳空间在支撑件31上的投影。这样，如图7b所示，在向注入孔352注入胶状液体时，胶状液体可依次通过注入孔352、下背胶点胶槽351、支撑件点胶槽313以及上背胶豁口321、垫片豁口342和间隙所形成的容纳空间，以对如图5所示的柔性屏20、支撑件31以及折叠组件10进行辅助粘接。由此，可增加胶状液体的容纳量，由于胶状液体凝固后形成点胶结构33，因此，能够增加点胶结构33的面积，从而进一步增加折叠组件10、支撑件31和柔性屏20之间的粘接强度，进而减少上背胶结构32与柔性屏20或支撑件31产生脱粘的情况，并进一步减少因脱粘产生的异常噪声。
此外，如图7b所示，注入孔352的数量与下背胶点胶槽351的数量相同且位置一一对应，这样，在制作可折叠手机时，可向每个注入孔352注入胶状液体，每个注入孔352中的胶状液体均可以通过下背胶点胶槽351和支撑件点胶槽313，流动至上背胶结构32和垫片34之间的间隙中，因此，能够使得胶状液体所形成的点胶结构33尽可能均匀地分布在间隙中，从而进一步增加了支撑件31与柔性屏20之间的粘接强度。
在本申请实施例中，垫片34的厚度与上背胶结构32的厚度相同，这样，在组装柔性屏20、支撑件31和折叠组件10后，进行辊压工序的过程中，各点胶槽能够很好地容纳点胶。此外，还能够避免因支撑件31的两侧厚度不均而产生的屏幕局部凹陷等问题，以减轻屏幕点胶后表面光影凹陷效果。
在本申请实施例中，垫片34可以为无粘性垫片34，具体可以为无粘性薄膜，这样，在可折叠手机折叠或展开的过程中，无粘性薄膜不会与柔性屏20之间产生脱粘，也就不会产生额外的异常噪声。
如图7b所示，点胶结构33设置于下背胶点胶槽351、支撑件点胶槽313、上背胶豁口321和垫片豁口342以及垫片边缘341与背胶边缘322之间的间隙内，具体可为在制作可折叠手机的过程中，通过注入孔352注入胶状液体后，胶状液体经注入孔352流动至下背胶点胶槽351、支撑件点胶槽313、上背胶豁口321和垫片豁口342内所形成的结构。点胶结构33能够增加柔性屏20与折叠组件10之间的粘接强度，使得在可折叠手机折叠或展开的过程中上背胶结构32与柔性屏20和支撑件31，以及下背胶结构35与支撑件31和折叠组件10不易产生脱粘的情况，因此，能够在一定程度上降低因脱粘产生的异常噪声。
此外，如图8所示，由于支撑件点胶槽313的部分在柔性屏20上的投影位于弯折区域21内，其他部分在柔性屏20上的投影位于非弯折区域22内，则点胶结构33的部分在柔性屏20上的投影位于弯折区域21内，其他部分在柔性屏20上的投影位于非弯折区域22内。
进一步地，点胶结构33可以采用胶水凝固而成。
在本申请的另一实施例中，与图8所示实施例的区别在于支撑件31与折叠组件10之间的粘接结构不同。具体地，图8所示的实施例中，支撑件31与柔性屏20之间设置有上背胶结构32、点胶结构33和垫片34，支撑件31与折叠组件10之间仅设置下背胶结构35和点胶结构33，也就是说，支撑件31与柔性屏20之间的粘接结构，与支撑件31和折叠组件10之间的粘接结构不同。在本实施例中，如图11所示，支撑件31与折叠组件10之间的粘接结构，与支撑件31与柔性屏20之间的粘接结构相同。
具体地，如图10所示，在支撑件31的两侧均设置一个上背胶结构32和一个垫片34。也就是说，参照图11，在支撑件31和折叠组件10之间也设置有上背胶结构32、点胶结构33和垫片34。支撑件31与折叠组件10之间的上背胶结构32在折叠组件10上的投影，位于折叠组件10的非运动区域12内，也就是说，上背胶结构32与运动区域11无重叠。这样，在可折叠手机折叠或展开的过程中，上背胶结构32不会与折叠组件10发生脱粘以及粘接的情况，因此，也能够尽可能减少因反复脱粘以及粘接而产生的异常噪声。此外，由于在支撑件31和折叠组件10之间除设置上背胶结构32之外，还设有点胶结构33，因此，支撑件31与折叠组件10之间的粘接强度能够满足强度要求。
在本申请的另一实施例中，与图8所示实施例的区别在于垫片34与上背胶结构32之间的位置关系以及点胶结构33。具体地，如图12a所示，垫片34的垫片边缘341和上背胶结构32的背胶边缘322相接触，垫片34靠近上背胶结构32的垫片边缘341上设置有垫片豁口342，且垫片豁口342在垫片34上的设置位置，与上背胶豁口321在上背胶结构32上的设置位置相对应。因此，垫片豁口342与上背胶豁口321合围形成合成点胶槽343。合成点胶槽343与支撑件点胶槽313连通，具体地，合成点胶槽343在支撑件31上的投影与支撑件点胶槽313完全重合。这样，支撑件点胶槽313、下背胶点胶槽351和合成点胶槽343均连通。在制作可折叠手机时，如图12b所示，当向下背胶结构35的注入孔352注入胶状液体时，胶状液体可通过注入孔352依次流动至下背胶点胶槽351、支撑件点胶槽313以及合成点胶槽343，形成点胶结构33。
点胶结构33可对柔性屏20、支撑件31以及折叠组件10进行辅助粘接。由于下背胶点胶槽351、支撑件点胶槽313以及合成点胶槽343的横截面形状均为封闭形状，因此能够很好地容纳胶状液体，从而使得胶状液体凝固后形成的点胶结构33能够很好地对柔性屏20、支撑件31和折叠组件10提供粘接作用。
在本申请的另一实施例中，与图8所示实施例的区别在于上背胶结构32、垫片34的结构以及点胶结构33的设置位置。具体地，如图13所示，在本实施例中，上背胶结构32的背胶边缘322为直线，例如，上背胶结构32上不设置上背胶豁口321。在垫片34上设置呈封闭形状的垫片点胶槽344，垫片点胶槽344、支撑件点胶槽313 和下背胶点胶槽351相互连通，且垫片点胶槽344在支撑件31上的投影、下背胶点胶槽351在支撑件31上的投影与支撑件点胶槽313均重合。
需要说明的是，支撑件点胶槽313在柔性屏20上的投影，可位于柔性屏20的弯折区域21内，这样，点胶结构33在柔性屏20上的投影，位于柔性屏20的弯折区域21内，由于上背胶结构32的背胶边缘322为直线，因此，本实施例中上背胶结构32拥有更大的背胶面积，从而能够进一步增加支撑件31与柔性屏20之间的粘接强度，降低因支撑件31与柔性屏20之间发生脱粘而产生的异常噪声。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
