在所述显示模组的厚度方向上，所述第一连接板件的高度小于所述第一金属板件的高度以及所述第二金属板件的高度。
所述第一连接板件包括金属部及有机材料部。所述金属部包括第一面和第二面。所述第一面面向所述显示屏。所述第二面与所述第一面相背设置。所述金属部设有多个通孔。各所述通孔自所述第一面贯穿至所述第二面。所述有机材料部位于所述多个通孔内且固接所述金属部。
可以理解的是，金属部的硬度及刚度大于有机材料部的刚度及硬度。此时，因为第一连接板件同时具有金属部及有机材料部，所以第一连接板件的整体刚度及硬度较为适中。当电子设备处于打开状态时，第一连接板件具有足够的刚度及硬度来支撑显示屏的弯折区，以防止显示屏的弯折区出现塌陷的问题，也即保证显示屏具有较佳的表面平整度。当电子设备在展开或者折叠的过程中，因为第一连接板件具有较佳的柔韧性，所以第一连接板件对显示屏的弯折影响较小。换言之，在电子设备的折叠过程中或者展开的过程中，有机材 料部能够吸收在弯折时所产生的应力。
此外，转动装置的第一支撑板、第二支撑板及第三支撑板上一般设置有较多的凹槽或者通孔。该凹槽或者通孔可以作为部件的避让空间或者用于锁紧紧固件。而在第一连接板件设置有通孔，且通孔内未设置有机材料部的方案中，当电子设备处于打开状态时，转动装置的第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘容易挤压第一连接板件。因为通孔的周缘的应力较为集中，所以通孔的周缘能够以较大的挤压力挤向光学胶，光学胶发生凸出，以使显示屏出现黑斑或者亮线等问题。而在本实施方式中，通过将有机材料部设置在金属部的通孔内，从而当转动装置的第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘挤压第一连接板件时，有机材料部可以吸收部分挤压力，从而防止通孔的周缘的应力过于集中，也即防止光学胶因过度挤压而发生凸出，进而避免显示屏出现黑斑或者亮线等问题。
此外，第一金属板件与第二金属板件的硬度与刚度较大。此时，当电子设备在折叠过程中或者展开的过程中，第一金属板件具有较佳的硬度及刚度来支撑显示屏的第一非弯折区，第二金属板件具有较佳的硬度及刚度来支撑显示屏的第二非弯折区，从而防止显示屏出现塌陷的问题，也即保证显示模组具有较佳的表面平整度。
此外，第一金属板件、第一连接板件及第二金属板件能够形成一个整体部件(支撑件)。此时，作为一个整体部件的支撑件安装于显示屏的方式较为简单，也即显示模组的组装方式能够得到简化。
一种实现方式中，所述第一金属板件、所述金属部及所述第二金属板件为一体成型结构，也即第一金属板件、金属部及第二金属板件为一个整体结构。此时，第一金属板件、金属部及第二金属板件之间的连接牢固度更佳。此外，第一金属板件、金属部及第二金属板件的形成步骤较少，可以减少支撑件的投入成本。
一种实现方式中，所述多个通孔形成多个第一通孔组。所述多个第一通孔组在第一方向上排布。各所述第一通孔组均包括多个第一通孔。同一个所述第一通孔组内的多个第一通孔在第二方向上间隔排布。相邻两个所述第一通孔组的多个第一通孔彼此交叉排布。所述第二方向为所述第一金属板件朝向所述第二金属板件的方向。所述第一方向垂直于所述第二方向。例如，所述第一方向为所述电子设备的宽度方向，也即X轴方向。所述第二方向为所述电子设备的长度方向，也即Y轴方向。
在本实施方式中，通过在金属部设置第一通孔组，可以提高第一连接板件的整体柔韧性，保证显示模组具有较佳的柔韧性。再者，在第一通孔内设置有机材料部时，第一连接板件的整体柔韧性可以进一步地提高。此时，当电子设备在折叠或者展开的过程中，设置在第一通孔组内的有机材料部可以有效地吸收弯折力，也即避免金属部的侧面因应力过大而造成显示模组不容易弯折。
一种实现方式中，所述多个通孔还形成两个第二通孔组。所述两个第二通孔组分别位于所述多个第一通孔组的两侧。各所述第二通孔组均包括多个第二通孔。同一个所述第二通孔组内的多个第二通孔在所述第二方向上间隔排布，且每个所述第二通孔均贯穿所述金属部的侧面。
在本实施方式中，通过多个第二通孔贯穿金属部的侧面，以防止金属部的侧部发生局 部应力集中。此时，在电子设备展开或者折叠过程中，第二通孔能够吸收显示模组在弯折过程中的应力，也即避免金属部的侧面因应力过大而造成显示模组不容易弯折。
一种实现方式中，所述第一通孔为条形孔。所述第一通孔的延伸方向平行于所述第一方向。在所述第二方向上，所述第一通孔的宽度在0.15毫米至3毫米的范围内。
在本实施方式中，当第一通孔的延伸方向平行于X轴方向，且在Y轴方向上第一通孔的宽度在0.15毫米至3毫米的范围内时，在X-Y平面上金属部形成的镂空区域的面积较大。此时，设置于第一通孔内的有机材料部在X-Y平面上的面积也较大。因此，在电子设备展开或者折叠过程中，有机材料部能够吸收弯折过程中的应力，也即避免金属部因应力过大而造成显示模组不容易弯折，从而提高显示模组的弯折效果。
可以理解的是，为了能够保证支撑件具有较大的硬度及刚度，一般支撑件开设的通孔都比较小。而在本实施方式中，通过在第一通孔内设置有机材料部，有机材料部可以一定程度地提高第一连接板件的硬度及刚度，此时，金属部上开设的第一通孔的尺寸较大(具体的，在Y轴上，第一通孔的宽度的最大值可以达到3毫米)。此外，在支撑件加工过程中，可以较大程度地减少第一通孔的加工数量，从而节省支撑件的投入成本。
一种实现方式中，在所述第二方向上，同一个所述第一通孔组内的相邻两个所述第一通孔之间的距离在0.05毫米至0.8毫米的范围内。
可以理解的是，为了能够保证支撑件具有较大的柔韧性，一般支撑件上的相邻两个第一通孔之间的距离都比较小，也即第一通孔之间的金属部的尺寸较小。而在本实施方式中，两个第一通孔之间的距离可以做得较大(例如，在Y轴上，两个第一通孔之间的距离的最大值可以达到0.8毫米)。此时，通过在第一通孔内设置有机材料部，从而既可以保证支撑件具有较佳的硬度及刚度，又可以一定程度地提高支撑件的柔韧性。
一种实现方式中，所述有机材料部注塑连接所述金属部，也即有机材料部通过注塑工艺形成金属部上，并与金属部连接。
可以理解的是，有机材料部通过注塑与金属部连接，可以提高有机材料部与金属部的连接牢固度，且有机材料部与金属部形成的第一连接板件的整体性较佳。
一种实现方式中，所述有机材料部的材质包括P4U，所述有机材料部的材质还包括PU、TPU、TPE、TPR、TPV及EVA中的至少一种。
可以理解的是，当电子设备处于正常使用的状态(也即，电子设备未处于碰撞或者冲击的状态下)时，P4U与PU能够保持较柔软的状态，也即第一连接板件的弹性模量较小。此时，当电子设备在展开或者折叠的过程中，第一连接板件对显示屏的折叠或者展开的影响较小，也即P4U与PU能够保证第一连接板件具有较佳的弯折性。
此外，当电子设备处于碰撞或者冲击状态下，P4U与PU将受到金属部的剧烈碰撞或冲击。此时，P4U与PU内的分子能够立刻相互锁定，迅速收缩变硬。此时，第一连接板件的弹性模量显著提高，从而防止显示屏受到第一连接板件的挤压而发生变形。当P4U与PU受到的冲击力或者挤压力消失时，P4U与PU能够快速地恢复至柔软状态，也即P4U与PU从硬到软发生变化，从而保证显示模组能够继续实现弯折或者展开。
一种实现方式中，所述有机材料部的材质包括紫外固化胶或者热固化胶。
在本实施方式中，当所述有机材料部的材质包括紫外固化胶或者热固化胶时，有机材 料部与金属部的连接牢固度较佳，且有机材料部与金属部形成的第一连接板件的整体性较佳。此外，有机材料部的形成方式较为简单，容易操作。
一种实现方式中，在所述显示模组的厚度方向上，所述金属部的高度在0.015毫米至0.3毫米的范围内。这样，在保证第一连接板件的硬度及刚度的同时，又能够使得第一连接板件的柔韧性较佳。换言之，第一连接板件的硬度及刚度适中。
一种实现方式中，在所述显示模组的厚度方向上，所述第一金属板件及所述第二金属板件的高度在0.1毫米至0.5毫米的范围内。这样，第一金属板件与第二金属板件具有足够的硬度及刚度，从而在电子设备展开或者折叠的过程中，第一金属板件与第二金属板件能够有效地支撑显示屏。此外，第一金属板件与第二金属板件的厚度较薄，第一金属板件与第二金属板件也不会较大程度增加显示模组的厚度。
一种实现方式中，所述支撑件还包括缓冲件。所述缓冲件固定于所述显示屏与所述第一连接板件之间，或者，所述缓冲件固定于所述第一连接板件远离所述显示屏的表面。
所述缓冲件固定于所述显示屏与所述第一连接板件之间。此时，当第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘挤压第一连接板件时，第一连接板件将挤压力传递至缓冲件。此时，缓冲件可以吸收部分挤压力，从而进一步地避免显示屏因过度挤压而出现黑斑或者亮线等问题。
此外，当第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘挤压第一连接板件时，若第一连接板件发生断裂，并挤向显示屏。此时，缓冲件也可以防止断裂的第一连接板件直接刺穿或者挤向显示屏，从而较大程度地避免显示屏出现黑斑或者亮线等问题。
所述缓冲件固定于所述第一连接板件远离所述显示屏的表面。
可以理解的是，通过在第一连接板件背离显示屏的表面设置缓冲件，从而进一步地提高面向显示屏的弯折区设置的支撑件的柔韧性。当电子设备在展开或者折叠的过程中，面向弯折区设置的支撑件具有较佳的柔韧性，从而避免因支撑件的硬度及刚度较大而影响显示屏的弯折，也即，在电子设备的折叠过程中或者展开的过程中，缓冲件能够吸收在弯折时所产生的应力。
此外，通过在第一连接板件背离显示屏的表面设置缓冲件，从而当电子设备处于打开状态时，转动装置的第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘挤压在缓冲件上。这样，缓冲件能够吸收部分挤压力。此时，金属部的通孔的周缘的应力不会较为集中，也即金属部的通孔的周缘挤压显示屏的力较小，从而较大程度地防止显示屏出现黑斑或者亮线等问题。
一种实现方式中，所述缓冲件与所述有机材料部为一体成型结构。此时，缓冲件与有机材料部的整体性较佳，连接牢固度也较佳。
一种实现方式中，所述支撑件包括金属片。所述支撑板还包括固定胶。所述固定胶固定于所述金属片与所述第一连接板件之间。
可以理解的是，当第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘挤压第一连接板件时，第一连接板件将挤压力传递至金属片。此时，因为金属片的整体性较佳，金属片不容易因发生断裂而刺穿或者挤压显示屏，从而较大程度地防止显示屏出现黑 斑或者亮线等问题。
此外，当第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘挤压第一连接板件时，若第一连接板件的金属部发生断裂，并挤向显示屏。此时，因为第一连接板件与显示屏之间设置有金属片，所以金属片可以防止金属部直接刺穿或者挤压显示屏，从而较大程度地防止显示屏出现黑斑或者亮线等问题。
一种实现方式中，所述支撑件还包括第一子缓冲件及第二子缓冲件。所述第一子缓冲件固定于所述显示屏与所述第一连接板件之间。所述第二子缓冲件固定于所述第一连接板件远离所述显示屏的表面。
可以理解的是，第一子缓冲件、第二子缓冲件及第一连接板件的相互配合，此时，面向显示屏的弯折区设置的支撑件的整体刚度与硬度较为适中。当电子设备处于打开状态时，支撑件具有足够的刚度及硬度来支撑显示屏的弯折区，从而防止显示屏的弯折区出现塌陷或者凹坑的问题，也即保证显示模组具有较佳的表面平整度。
此外，通过在第一连接板件靠近显示屏的表面设置第一子缓冲件，在第一连接板件背离显示屏的表面设置第二子缓冲件，从而显著地提高面向显示屏的弯折区设置的支撑件的柔韧性。此时，当电子设备在展开或者折叠的过程中，面向弯折区设置的支撑件具有较佳的柔韧性，从而防止显示模组因支撑件的硬度及刚度较大而影响显示屏的弯折，也即，在电子设备的折叠过程中或者展开的过程中，缓冲件能够吸收弯折过程时所产生的应力。
此外，通过在第一连接板件靠近显示屏的表面设置第一子缓冲件，在第一连接板件背离显示屏的表面设置第二子缓冲件，从而当电子设备处于打开状态时，转动装置的第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘挤压在第二子缓冲件。这样，因为第二子缓冲件具有较佳的柔韧性，所以第二子缓冲件具有足够的柔韧性来吸收部分挤压力。此时，金属部的通孔的周缘的应力不会较为集中，也即金属部的通孔的周缘挤压显示屏的力较小，从而较大程度地防止显示屏出现黑斑或者亮线等问题。此外，当第二子缓冲件将部分挤压力通过第一连接板件传递至第一子缓冲件，第一子缓冲件也能够再次吸收部分挤压力。此时，显示屏受到较大的挤压力进一步地减少，从而较大程度地防止显示屏出现黑斑或者亮线等问题。
一种实现方式中，所述第一子缓冲件、所述有机材料部以及所述第二子缓冲件为一体成型结构。此时，所述第一子缓冲件、所述有机材料部以及所述第二子缓冲件的整体性较佳，连接牢固度也较佳。
一种实现方式中，所述支撑件还包括面向所述显示屏的弯折区的第二连接板件及第三金属板件，且所述第一金属板件、所述第二连接板件、所述第三金属板件、第一连接板件以及所述第二金属板件依次连接。在所述显示模组的厚度方向上，所述第二连接板件的高度小于所述第一金属板件的高度以及所述第二金属板件的高度。所述第二连接板件设有所述通孔。所述第二连接板件包括所述金属部及位于所述通孔的所述有机材料部。所述有机材料部固接于所述金属部。
在本实施方式中，因为第二连接板件同时具有金属部以及有机材料部，所以第二连接板件的整体硬度及刚度较为适中，也即支撑件的部分区域具有较佳的柔韧性。此时，支撑件的柔韧性较佳的区域的数量可以提高。故而，在支撑件固定于显示屏时，第二连接板件 也可以固定于显示屏的弯折区中弯曲角度较大的区域，以保证显示屏的弯折区具有较佳的弯折效果。

此外，通过将有机材料部设置在金属部的通孔内，从而提高第一连接板件的柔韧性，此时，当转动装置的第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘挤压第一连接板件时，有机材料部具有足够的柔韧性来吸收部分挤压力，从而防止通孔的周缘的应力过于集中，也即防止光学胶因过度挤压而发生凸出，进而避免显示屏出现黑斑或者亮线等问题。
此外，通过在金属部的通孔内设置有机材料部，从而使得金属部与有机材料部形成一体结构，也即第一连接板件的整体性较佳。此时，金属部与有机材料部的连接牢固度较佳。故而，当第一支撑板、第二支撑板及第三支撑板上的凹槽或者通孔的周缘挤压第一连接板件时，因为金属部与有机材料部的连接牢固度较佳，所以金属部不容易因发生断裂而刺穿或者挤压显示屏。

具体实施方式
请参阅图1，图1是本申请实施例提供的电子设备处于打开状态下的结构示意图。电子设备100可以为平板电脑、手机、照相机、个人计算机、笔记本电脑、车载设备或者可穿戴设备。图1所示实施例的电子设备100以手机为例进行阐述。其中，为了便于描述，如图1所示，定义电子设备100的宽度方向为X轴。电子设备100的长度方向为Y轴。电子设备100的厚度方向为Z轴。
请参阅图2，并结合图1所示，图2是图1所示电子设备处于折叠状态下的结构示意图。
电子设备100包括第一壳体10、第二壳体20及显示模组30。第一壳体10和第二壳体20能够相对展开，以处于打开状态。第一壳体10和第二壳体20也能够相对折叠，以处于闭合状态。换言之，第一壳体10和第二壳体20能够在闭合状态和打开状态之间相互切换。其中，图1示意了电子设备100处于打开状态。图2示意了电子设备100处于闭合状态。
此外，显示模组30可以用于显示图像和视频等。显示模组30包括第一部分34、第二部分35及第三部分36。第二部分35连接于第一部分34与第三部分36之间。第一部分34、第二部分35与第三部分36均位于第一壳体10与第二壳体20的同一侧。此外，第一部分34固定于第一壳体10。第二部分35位于第一壳体10与第二壳体20之间。第三部分36固定于第二壳体20。
可以理解的是，当电子设备100处于打开状态时，第一部分34、第二部分35及第三部分36大致呈180°(允许些微偏差，例如165°、177°或者185°)。此时，显示模组30具有连续的大面积显示区域，也即显示模组30能够实现大屏显示，用户的体验性较佳。 当电子设备100处于闭合状态时，显示模组30相互折叠。具体的，第二部分35发生弯折。第一部分34与第三部分36在Z方向上相互重叠。此时，显示模组30的展开面积较小，有利于降低显示模组30发生损坏的概率。
此外，附图2示意了当电子设备100处于闭合状态时，显示模组30处于第一壳体10与第二壳体20之间，也即显示模组30能够内折。在其他实施方式中，当电子设备100处于闭合状态时，第一壳体10与第二壳体20也可以位于第一部分34与第三部分36之间，也即显示模组30可以外折。具体的本实施例不做限定。
此外，附图1与附图2均示意了电子设备100可以发生一次折叠。在其他实施方式中，电子设备100也可以发生多次折叠，也即显示模组20可以包括多个部分。每两个部分之间可以发生折叠。
可以理解的是，第一壳体10和第二壳体20有多种连接关系，例如转动连接、滑动连接、可拆卸式扣合连接等。在本实施例中，以第一壳体10转动连接第二壳体20为例进行说明。请参阅图3与图4，图3是图1所示的电子设备100的部分分解示意图。图4是图3所示的电子设备的转动装置安装于第一壳体与第二壳体的示意图。电子设备100还包括转动装置40。转动装置40连接第一壳体10与第二壳体20。转动装置40能够使第一壳体10和第二壳体20相对转动以折叠或展开。转动装置40位于第一壳体10和第二壳体20之间，且转动装置40与显示模组30的第二部分35相对设置。
其中，转动装置40可以包括第一支撑板41、第二支撑板42及第三支撑板43。第二支撑板42位于第一支撑板41与第三支撑板43之间。此外，第一支撑板41、第二支撑板42及第三支撑板43与显示模组30的第二部分35面向设置。
此外，第二支撑板42的一侧活动连接于第一支撑板41。第二支撑板42的另一侧也活动连接于第三支撑板43。换言之，第一支撑板41、第二支撑板42及第三支撑板43彼此之间能够相互活动。此外，第一支撑板41背离第二支撑板42的一侧活动连接于第一壳体10。第三支撑板43背离第二支撑板42的一侧活动连接于第二壳体20。此时，通过第一支撑板41、第二支撑板42及第三支撑板43的相互配合，第一壳体10与第二壳体20能够相对转动以折叠或展开。
可以理解的是，当电子设备100展开至打开状态时，第一支撑板41、第二支撑板42与第三支撑板43共同支撑显示模组30的第二部分35。

请参阅图7，图7是图4所示的电子设备的显示模组在A-A线处的一种实施方式的部分剖面示意图。显示屏31可以包括依次层叠设置的背膜311、显示面板312、偏光片313(Polarizer，POL)及保护盖板314。换言之，显示面板312位于背膜311与偏光片313之间。保护盖板314固定于偏光片313背离显示面板312的表面。背膜311可用于支撑显示面板312。显示面板312用于显示图像及视频等。保护盖板314用于保护偏光片313及显示面板312等。
此外，显示屏31还包括光学胶315。光学胶315固定于偏光片313与保护盖板314之间。光学胶315既可以使得显示面板312发出的显示光线传播出电子设备100的外部，又可以提高显示模组30的柔韧性。
一种实施方式中，显示屏31可以为触控屏。显示屏31能够用于根据用户的触控动作产生触控信号。具体的，当用户在显示屏31上点击摄像软件的图标时，显示屏31能够根据用户的点击动作产生触控信号，并将触控信号传输至电子设备100的处理器(图未示)。处理器接收触控信号，并根据触控信号打开摄像软件。处理器可以安装于第一壳体10(请参阅图4)，也可以安装于第二壳体20(请参阅图4)。
其中，显示面板312可以具有触控功能，也即显示面板312具有触控面板的功能。例如，采用on-cell技术将触控面板嵌入到显示面板312的发光层上。在其他实施方式中，显示面板312也可以不具有触控功能。此时，显示屏31还包括触控面板(图未示)。触控面板可以固定在保护盖板314与偏光片313之间，也可以位于偏光片313与显示面板312之间。
请再次参阅图7，显示屏31包括相背设置的外表面316及内表面317。显示屏31的外表面316指的是用户在正常使用电子设备100时，显示屏31朝向用户的表面，也即显示屏31的显示侧。显示屏31的内表面317指的是当显示模组30安装于第一壳体10与第二壳体20时，显示屏31朝向电子设备100的内部的表面，也即显示屏31的非显示侧。显示模组30的支撑件32固定于显示屏31的内表面317。一种实施方式中，支撑件32可以通过OCA光学胶、PVB胶、泡棉胶或其组合材质等固定于显示屏31的内表面317。附图7示意了支撑件32与显示屏31的内表面317之间设置有光学胶39。
在本申请中，支撑件32的结构具有多种设置方式。下文将结合相关附图具体介绍四种支撑件32的设置方式。可以理解的是，在每个实施例中，支撑件32的结构均具有较佳的柔韧性以及较佳的强度和硬度。此外，支撑件32也具有较佳的整体性以及表面平整度。
第一种实施例：请再次参阅图7，支撑件32包括第一金属板件321、第一连接板件322、 第二金属板件323及缓冲件324。第一连接板件322连接于第一金属板件321与第二金属板件323之间。缓冲件324位于第一金属板件321与第二金属板件323之间，且缓冲件324固定于第一连接板件322与显示屏31之间。附图7通过虚线区别开第一金属板件321、第一连接板件322、第二金属板件323。可以理解的是，第一金属板件321朝向第二金属板件323的方向为电子设备100的长度方向，也即Y轴的正方向。垂直于第一金属板件321朝向第二金属板件323的方向为X轴方向。
此外，在Z方向上，第一连接板件322的高度为H1。第一金属板件321的高度为H2。第二金属板件323的高度为H3。H1小于H2。H1小于H3。
此外，结合附图6所示，第一金属板件321面向第一弯折区3181设置。第一金属板件321为显示模组30的第一部分34的一部分。第一连接板件322与缓冲件324均面向弯折区3182设置。第一连接板件322与缓冲件324均为第二部分35的一部分。第二金属板件323面向第二非弯折区3183设置。第二金属板件323为第三部分36的一部分。第一连接板件322与缓冲件324均能够发生弯折。
请再次参阅图6及图7，当电子设备100处于闭合状态时，第一连接板件322与缓冲件324发生弯折，第一金属板件321与第二金属板件323相对设置。附图6示意了支撑件32大致呈水滴型。在其他实施方式中，支撑件32的形状也可以呈环形。具体的，本申请不做限制。当电子设备100处于打开状态时，第一金属板件321、第一连接板件322、第二金属板件323及缓冲件324大致呈180°(允许些微偏差，例如165°、177°或者185°)。
其中，第一金属板件321与第二金属板件323的材质为金属材料。例如，第一金属板件321与第二金属板件323可以为但不仅限于为铜、铝、铍铜、不锈钢或者钛合金等。此时，第一金属板件321与第二金属板件323具有较佳的硬度及刚度。
缓冲件324的材质可以为但不仅限于为高分子材料。此时，缓冲件324具有较佳的柔韧性。
请参阅图7，第一连接板件322包括金属部3221及有机材料部3222。金属部3221包括相背设置的第一面3223及第二面3224。第一面3223面向显示屏31。金属部3221设有多个通孔3225。各通孔3225自第一面3223贯穿至第二面3224。有机材料部3222位于多个通孔3225内，并固接于金属部3221。此外，缓冲件324覆盖金属部3221和有机材料部3222。可以理解的是，在Y轴的方向上，有机材料部3222的数量不仅限于附图7所示意的六个。
其中，金属部3221的材质可以为但不仅限于为铜、铝、铍铜、不锈钢或者钛合金等。此时，金属部3221具有较佳的硬度及刚度。
此外，有机材料部3222的材质可以为但不仅限于为高分子材料。此时，有机材料部3222具有较佳的柔韧性。
可以理解的是，金属部3221的硬度及刚度大于有机材料部3222的刚度及硬度。此时，因为第一连接板件322同时具有金属部3221及有机材料部3222，所以第一连接板件322的整体刚度及硬度较为适中。当电子设备100处于打开状态时，第一连接板件322具有足够的刚度及硬度来支撑显示屏31的弯折区3182，以防止显示屏31的弯折区3182出现塌陷的问题，也即保证显示屏31具有较佳的表面平整度。当电子设备100在展开或者折叠的 过程中，因为第一连接板件322具有较佳的柔韧性，所以第一连接板件322对显示屏31的弯折影响较小。换言之，在电子设备100的折叠过程中或者展开的过程中，有机材料部3222能够吸收在弯折时所产生的应力。
此外，转动装置40的第一支撑板41、第二支撑板42及第三支撑板43上一般设置有较多的凹槽或者通孔。该凹槽或者通孔可以作为部件的避让空间或者用于锁紧紧固件。而在第一连接板件322设置有通孔3225，且通孔3225内未设置有机材料部3222的方案中，当电子设备100处于打开状态时，转动装置40的第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘容易挤压第一连接板件322。因为通孔3225的周缘的应力较为集中，所以通孔3225的周缘能够以较大的挤压力挤向光学胶39，光学胶39发生凸出，以使显示屏31出现黑斑或者亮线等问题。而在本实施方式中，通过将有机材料部3222设置在金属部3221的通孔3225内，从而当转动装置40的第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压第一连接板件322时，有机材料部3222可以吸收部分挤压力，从而防止通孔3225的周缘的应力过于集中，也即防止光学胶39因过度挤压而发生凸出，进而避免显示屏31出现黑斑或者亮线等问题。
此外，当第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压第一连接板件322时，第一连接板件322将挤压力传递至缓冲件324。此时，缓冲件324可以吸收部分挤压力，从而进一步地避免显示屏31因过度挤压而出现黑斑或者亮线等问题。
此外，当第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压第一连接板件322时，若第一连接板件322发生断裂，并挤向显示屏31。此时，缓冲件324也可以防止断裂的第一连接板件322直接刺穿或者挤向显示屏31，从而较大程度地避免显示屏31出现黑斑或者亮线等问题。
此外，第一金属板件321与第二金属板件323的硬度与刚度较大。此时，当电子设备100在折叠过程中或者展开的过程中，第一金属板件321具有较佳的硬度及刚度来支撑显示屏31的第一非弯折区3181，第二金属板件323具有较佳的硬度及刚度来支撑显示屏31的第二非弯折区3183，从而防止显示屏31出现塌陷的问题，也即保证显示模组30具有较佳的表面平整度。
此外，第一金属板件321、第一连接板件322、第二金属板件323及缓冲件324能够形成一个整体部件(支撑件32)。此时，作为一个整体部件的支撑件32安装于显示屏31的方式较为简单，也即显示模组30的组装方式能够得到简化。
一种实施方式中，第一连接板件322的金属部3221的两侧分别连接第一金属板件321和第二金属板件323，且第一金属板件321、金属部3221及第二金属板件323为一体成型结构，也即第一金属板件321、金属部3221及第二金属板件323为一个整体结构。此时，第一金属板件321、金属部3221及第二金属板件323之间的连接牢固度更佳。此外，第一金属板件321、金属部3221及第二金属板件323的形成步骤较少，可以减少支撑件42的投入成本。
具体的，通过CNC加工在一个整体的板件上形成依次连接的第一金属板件321、第一连接板件322的金属部3221及第二金属板件323。在其他实施方式中，也可以通过注塑工 艺或者化学腐蚀等方式形成依次连接的第一金属板件321、金属部3221第一连接板件322及第二金属板件323。
在其他实施方式中，第一金属板件321、金属部3221及第二金属板件323也可以通过焊接形成或者卡扣扣合连接。
一种实施方式中，第一金属板件321、第二金属板件323及第一连接板件322的金属部3221的材质相同。此时，支撑件32的物料种类较少，可以节省支撑件32的物料准备步骤，减少支撑件42的投入成本。
一种实施方式中，第一金属板件321、第一连接板件322的金属部3221、第二金属板件323一次成型。可以理解的是，一次成型包括挤出成型、注射成型、模压成型、压延成型等方式。这样，支撑件32的加工工艺步骤较少，可以减少支撑件32的成本投入。
请再次参阅图7，在Z方向上，也即在显示模组30的厚度方向上，金属部3221的高度H1在0.015毫米至0.3毫米的范围内。这样，在保证第一连接板件322的硬度及刚度的同时，又能够使得第一连接板件322的柔韧性较佳。换言之，第一连接板件322的硬度及刚度适中。
请再次参阅图7，在Z方向上，第一金属板件321的高度H2与第二金属板件323的高度H3在0.1毫米至0.5毫米的范围内。这样，第一金属板件321与第二金属板件323具有足够的硬度及刚度，从而在电子设备100展开或者折叠的过程中，第一金属板件321与第二金属板件323能够有效地支撑显示屏31。此外，第一金属板件321与第二金属板件323的厚度较薄，第一金属板件321与第二金属板件323也不会较大程度增加显示模组30的厚度。
请参阅图8，图8是图7所示的显示模组的第一连接板件的部分结构示意图。金属部3221设有多个第一通孔组M及两个第二通孔组N。两个第二通孔组N分别位于多个第一通孔组M的两侧。附图8示意了在X轴的正方向的一个第二通孔组N。可以理解的是，在X轴的负方向的也相应设置有一个第二通孔组N。当然，在其他实施方式中，金属部3221也可以不设置两个第二通孔组N。
多个第一通孔组M在X轴方向上排布。可以理解的是，在X轴方向上，每两个第一通孔组M可以相互平行设置，但也可以允许些微偏差，例如155°、166°或者177°。此外，每个第一通孔组M均包括多个第一通孔3226。多个第一通孔3226在Y轴方向上间隔排布。可以理解的是，在Y轴方向，每两个第一通孔3226的连线可以相互平行设置，但可以允许些微偏差，例如155°、166°或者177°。此外，附图8示意了相邻两个第一通孔组M的多个第一通孔3226彼此交叉排布，也即相邻两个第一通孔组M的第一通孔3226之间具有重叠部分。在其他实施方式中，第一通孔组M的多个第一通孔3226也可以彼此间隔排布。
其中，各第二通孔组N均包括多个第二通孔3227。同一个第二通孔组N的多个第二通孔3227在Y轴方向上间隔排布。可以理解的是，在Y轴方向，每两个第二通孔3227可以相互平行设置，但可以允许些微偏差，例如155°、166°或者177°。此外，同一个第二通孔组N的多个第二通孔3227贯穿金属部3222的侧面。附图8示意了在X轴的正方向的第二通孔组N的多个第二通孔3227贯穿金属部3222的侧面。
此外，附图8示意了每个第二通孔3227的至少部分位于两个第一通孔3226之间，也 即第二通孔3227与第一通孔3226具有重叠部分。在其他实施方式中，每个第二通孔3227也可以与第一通孔3226间隔设置。
在本实施方式中，通过在金属部3221设置第一通孔组M及两个第二通孔组N，可以提高第一连接板件322的整体柔韧性，保证显示模组30具有较佳的柔韧性。再者，在第一通孔3226和第二通孔3227内设置有机材料部3222时，第一连接板件322的整体柔韧性可以进一步地提高。此时，当电子设备100在折叠或者展开的过程中，有机材料部3222可以有效地吸收弯折力，从而不会影响电子设备100的折叠及展开。
此外，通过多个第二通孔3227贯穿第一连接板件322的侧面，以防止第一连接板件322的侧部发生局部应力集中。此时，在电子设备100展开或者折叠过程中，第二通孔3227能够吸收显示模组30在弯折过程中的应力，也即避免第一连接板件322的侧面因应力过大而造成显示模组30不容易弯折。
请参阅图9并结合图8所示，图9是图8所示的第一连接板件未包括有机材料部的部分结构示意图。第一通孔3226为条形孔。第一通孔3226的延伸方向平行于X轴方向。在Y轴方向上，第一通孔3226的宽度d1在0.15毫米至3毫米的范围内。例如，d1等于0.15毫米、0.26毫米、1毫米、2毫米或者3毫米。在其他实施方式中，第一通孔3226的延伸方向也可以平行于Y轴方向。
在本实施方式中，当第一通孔3226的延伸方向平行于X轴方向，且在Y轴方向上第一通孔3226的宽度d1在0.15毫米至3毫米的范围内时，在X-Y平面上金属部3221形成的镂空区域的面积较大。此时，设置于第一通孔3226内的有机材料部3222在X-Y平面上的面积也较大。因此，在电子设备100展开或者折叠过程中，有机材料部3222能够吸收弯折过程中的应力，也即避免金属部3221因应力过大而造成显示模组30不容易弯折，从而提高显示模组30的弯折效果。
可以理解的是，为了能够保证支撑件32具有较大的硬度及刚度，一般支撑件开设的通孔都比较小。而在本实施方式中，通过在第一通孔3226内设置有机材料部3222，有机材料部3222可以一定程度地提高第一连接板件322的硬度及刚度，此时，金属部3221上开设的第一通孔3226的尺寸较大(具体的，在Y轴上，第一通孔3226的宽度d1的最大值可以达到3毫米)。此外，在支撑件32加工过程中，可以较大程度地减少第一通孔3226的加工数量，从而节省支撑件32的投入成本。
一种实施方式中，第二通孔3227为条形孔。第二通孔3227的延伸方向平行于X方向。在Y轴方向上，第二通孔3227的宽度d2在0.15毫米至3毫米的范围内。例如，d2等于0.15毫米、0.26毫米、1毫米、2毫米或者3毫米。在其他实施方式中，第二通孔3227的延伸方向也可以平行于Y方向。
本实施方式中，当第二通孔3227的延伸方向平行于X轴方向，且在Y轴上第二通孔3227的宽度d2在0.15毫米至3毫米的范围内时，在X-Y平面上金属部3221形成的镂空区域的面积较大。此时，设置于第二通孔3227内的有机材料部3222在X-Y平面上的面积也较大。因此，在电子设备100展开或者折叠过程中，有机材料部3222能够吸收显示模组30在弯折过程中的应力，也即避免金属部3221因应力过大而造成显示模组30不容易弯折，从而提高显示模组30的弯折效果。
可以理解的是，为了能够保证支撑件32具有较大的硬度及刚度，一般支撑件开设的通孔3225都比较小。而在本实施方式中，金属部3221上开设的第二通孔3227的尺寸可以开设得较大(具体的，在Y轴上，第二通孔3227的宽度的最大值可以达到3毫米)。此时，在支撑件32加工过程中，可以较大程度地减少第二通孔3227的加工数量，从而节省支撑件32的投入成本。
一种实施方式中，在Y轴方向上，同一个第一通孔组M内的相邻两个第一通孔3226之间的距离d3在0.05毫米至0.8毫米的范围内。例如，d3等于0.05毫米、0.1毫米、0.2毫米、0.5毫米、0.6毫米或者0.8毫米。
可以理解的是，为了能够保证支撑件32具有较大的柔韧性，一般支撑件32上的相邻两个通孔3225之间的距离都比较小，也即通孔3225之间的金属部3221的尺寸较小。而在本实施方式中，两个第一通孔3226之间的距离d3可以做得较大(例如，在Y轴上，两个第一通孔3226之间的距离d3的最大值可以达到0.8毫米)。此时，通过在通孔3225内设置有机材料部3222，从而既可以保证支撑件32具有较佳的硬度及刚度，又可以一定程度地提高支撑件32的柔韧性。
可以理解的是，设置于通孔3225内的有机材料部3222的形成方式具有多种方式。
第一种实施方式，请再次参阅图7至图9，有机材料部3222注塑连接金属部3221，也即有机材料部3222通过注塑工艺形成金属部3221上，并与金属部3221连接。
具体的，通过注塑工艺在金属部3221的通孔3225内注塑高分子材料。当高分子材料冷却固化后，高分子材料形成有机材料部3222。
可以理解的是，有机材料部3222通过注塑与金属部3221连接，可以提高有机材料部3222与金属部3221的连接牢固度，且有机材料部3222与金属部3221形成的第一连接板件322的整体性较佳。
一种实施方式中，有机材料部3222的材质包括PU、热塑性聚氨酯弹性体橡胶(Thermoplastic polyurethanes，TPU)、热塑性弹性体(Thermoplastic Elastomer，TPE)、热塑性橡胶材料(Thermo-Plastic-Rubber material，TPR)、热塑性硫化橡胶(thermoplastic polyolefin，TPV)、乙烯-醋酸乙烯共聚物(Ethylene Vinyl Acetate Copolymer，EVA)中的至少一种。有机材料部3222的材质还包括P4U。在本实施方式中，有机材料部3222的材质包括P4U以及PU。在其他实施方式中，有机材料部3222的材质也可以包括P4U、TPR以及TPV。
可以理解的是，当电子设备100处于正常使用的状态(也即，电子设备100未处于碰撞或者冲击的状态下)时，P4U与PU能够保持较柔软的状态，也即第一连接板件322的弹性模量较小。此时，当电子设备在展开或者折叠的过程中，第一连接板件322对显示屏31的折叠或者展开的影响较小，也即P4U与PU能够保证第一连接板件322具有较佳的弯折性。
此外，当电子设备100处于碰撞或者冲击状态下，P4U与PU将受到金属部3221的剧烈碰撞或冲击。此时，P4U与PU内的分子能够立刻相互锁定，迅速收缩变硬。此时，第一连接板件322的弹性模量显著提高，从而防止显示屏31受到第一连接板件322的挤压而发生变形。当P4U与PU受到的冲击力或者挤压力消失时，P4U与PU能够快速地恢复至柔软状态，也即P4U与PU从硬到软发生变化，从而保证显示模组30能够继续实现弯折或者展 开。
一种实施方式中，缓冲件324与有机材料部3222为一体成型结构。此时，缓冲件324与有机材料部3222的整体性较佳，连接牢固度也较佳。
一种实施方式中，缓冲件324的材质与有机材料部3222的材质相同，也即缓冲件324的材质包括P4U。缓冲件324的材质还包括PU、TPU、TPE、TPR、TPV、EVA中的至少一种。此时，支撑件32的物料种类较少，可以节省支撑件32的物料准备步骤，减少支撑件42的投入成本。
一种实施方式中，缓冲件324与有机材料部3222一次成型。具体的，在通孔3225内注塑未固化的高分子材料时，未固化的高分子材料溢出通孔3225，并固化在第一金属板件321与第二金属板件323之间，形成缓冲件324。
在本实施方式中，通过将缓冲件324与有机材料部3222一次成型，这样支撑件32的加工工艺步骤较少，可以减少支撑件32的成本投入。
第二种实施方式，有机材料部3222通过紫外固化和热固化与金属部3221连接。具体的，有机材料部3222包括紫外固化胶或者热固化胶。
一种实施方式中，有机材料部3222包括紫外固化胶。具体的，通过在通孔3225内填充未固化的紫外固化胶。通过紫外光照射未固化的紫外固化胶。未固化的紫外固化胶在紫外光下固化形成有机材料部3222。
在本实施方式中，有机材料部3222通过紫外固化与金属部3221连接，可以提高有机材料部3222与金属部3221的连接牢固度，且有机材料部3222与金属部3221形成的第一连接板件322的整体性较佳。此外，有机材料部3222的形成方式较为简单，容易操作。
一种实施方式中，缓冲件324与有机材料部3222为一体成型结构。此时，缓冲件324与有机材料部3222的整体性较佳，连接牢固度也较佳。
一种实施方式中，缓冲件324的材质与有机材料部3222的材质相同，也即缓冲件324包括紫外固化胶。此时，可以节省支撑件32的物料准备步骤，减少支撑件42的投入成本。
一种实施方式中，缓冲件324与有机材料部3222一次成型。具体的，在通孔3225内填充未固化的紫外固化胶时，未固化的紫外固化胶溢出通孔3225。此时，通过紫外光同时照射通孔3225内的未固化的紫外固化胶，以及第一金属板件321与第二金属板件323之间的未固化的紫外固化胶。通孔3225内的未固化的紫外固化胶固化形成有机材料部3222。第一金属板件321与第二金属板件323之间的未固化的紫外固化胶固化形成缓冲件324。
在本实施方式中，通过将缓冲件324与有机材料部3222一次成型，这样，支撑件32的加工工艺步骤较少，可以减少支撑件32的成本投入。
一种实施方式中，有机材料部3222包括热固化胶。
具体的，通过在通孔3225内填充未固化的热固化胶。热固化胶可以为但不仅限于为胶水。此时，胶水在常温下可以自然固化，以形成有机材料部3222。
一种实施方式中，缓冲件324与有机材料部3222为一体成型结构。此时，缓冲件324与有机材料部3222的整体性较佳，连接牢固度也较佳。
一种实施方式中，缓冲件324的材质与有机材料部3222的材质相同，也即缓冲件324包括热固化胶。此时，支撑件32的物料种类较少，可以节省支撑件32的物料准备步骤， 减少支撑件42的投入成本。
一种实施方式中，缓冲件324与有机材料部3222一次成型。
具体的，在通孔3225内填充未固化的热固化胶，未固化的热固化胶溢出通孔3225，并流向第一金属板件321与第二金属板件323之间。通孔3225内的未固化的热固化胶固化形成有机材料部3222。第一金属板件321与第二金属板件323之间的未固化的热固化胶固化形成缓冲件324。
在本实施方式中，通过将缓冲件324与有机材料部3222一次成型，这样，支撑件32的加工工艺步骤较少，可以减少支撑件32的成本投入。
在其他实施方式中，支撑件32也可以不设置缓冲件324。此时，第一连接板件322与显示屏31之间为镂空区域。镂空区域指的是第一连接板件322与显示屏31之间填充空气。当当然，因为光学胶39具有弹性，所以当电子设备100在展开或者折叠的时候，通孔3225内可以允许少些部分光学胶39挤入。
在其他实施方式中，支撑件32也可以不包括缓冲件324。但支撑件32包括金属片324。具体的请参阅下文描述。
请参阅图10，图10是图4所示的电子设备的显示模组在A-A线处的另一种实施方式的部分剖面示意图。支撑件32包括金属片324。金属片324的材质可以为但不仅限于为铜、铝、铍铜、不锈钢或者钛合金等。支撑板32还包括固定胶3241。固定胶3241固定于金属片324与第一连接板件322之间。换言之，金属片324通过固定胶3241连接于第一连接板件322与显示屏31之间。可以理解的是，固定胶3241以为但不仅限于为双面胶、泡棉胶或者胶水。
具体的，当加工出一体成型结构的第一金属板件321、第一连接板件322以及第二金属板件323时，将金属片324通过固定胶3241固定在第一连接板件322朝向显示屏31的表面。此时，第一金属板件321、第一连接板件322、第二金属板件323及金属片324形成一个整体。
可以理解的是，当第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压第一连接板件322时，第一连接板件322将挤压力传递至金属片324。此时，因为金属片324的整体性较佳，金属片324不容易因发生断裂而刺穿或者挤压显示屏31，从而较大程度地防止显示屏31出现黑斑或者亮线等问题。
此外，当第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压第一连接板件322时，若第一连接板件322的金属部3222发生断裂，并挤向显示屏31。此时，因为第一连接板件322与显示屏31之间设置有金属片324，所以金属片324可以防止金属部3221直接刺穿或者挤压显示屏31，从而较大程度地防止显示屏31出现黑斑或者亮线等问题。
上文具体描述了有机材料部3222的形成方式。下文将再具体描述另一种结构的支撑件32。
请参阅图11，图11是图4所示的电子设备的显示模组在A-A线处的另一种实施方式 的部分剖面示意图。支撑件32还包括第二缓冲件3256及面向显示屏31的弯折区3182的第三金属板件3251及第二连接板件3252。此外，第二缓冲件3256固定于第二连接板件3252与显示屏31的弯折区3182之间。
在Z方向上，第二连接板件3252的高度H4小于第一金属板件321的高度H2以及第二金属板件323的高度H3。第二连接板件3252能够发生弯折。
第二连接板件3252设有通孔3225。第二连接板件3252包括金属部3221及位于通孔3225的有机材料部3222。有机材料部3222固接于金属部3221。
可以理解的是，本实施方式的通孔3225的设置方式可参阅上述各个实施方式中第一连接板件322的通孔3225的设置方式。这里不再赘述。本实施方式的金属部3221的材质及设置方式可参阅上述各个实施方式中第一连接板件322的金属部3221的材质及设置方式。这里不再赘述。本实施方式的有机材料部3222的材质及设置方式可参阅上述各个实施方式中第一连接板件322的有机材料部3222的材质及设置方式。这里不再赘述。
在本实施方式中，因为第二连接板件3252同时具有金属部3221以及有机材料部3222，所以第二连接板件3252的整体硬度及刚度较为适中，也即支撑件32的部分区域具有较佳的柔韧性。此时，支撑件32的柔韧性较佳的区域的数量可以提高。故而，在支撑件32固定于显示屏31时，第二连接板件3252也可以固定于显示屏31的弯折区3182中弯曲角度较大的区域，以保证显示屏31的弯折区具有较佳的弯折效果。
在其他实施例中，第二缓冲件3256也可以固定于第二连接板件3252远离显示屏31的表面，此时，第二连接板件3252固定于显示屏31。或者，在其他实施例中，支撑件32也可以不包括第二缓冲件3256。
在其他实施方式中，支撑件32还可以包括第四金属板件、第五金属板件、……、第S金属板件。S为大于等于六的整数。此外，支撑件32还可以包括第三连接板件、第四连接板件、……、第P连接板件。P为大于等于五的整数。第P连接板连接两个金属板件之间。第P连接板件设有通孔3225。所述第二连接板件包括金属部3221及位于通孔3225的有机材料部3222。有机材料部3222固接于金属部3221。
上文具体描述了显示模组30的第一种实施例：显示模组30包括缓冲件324。缓冲件324固定于第一连接板件322与显示屏31之间。下文通过相关附图具体描述第二种实施例：缓冲件324固定于第一连接板件322背离显示屏31的表面。
第二种实施例中，与第一种实施例相同的内容不再赘述。换言之，第一种实施例的大部分内容可以直接应用于第二种实施例。
请参阅图12，图12是图4所示的电子设备的显示模组在A-A线处的再一种实施方式的部分剖面示意图。缓冲件324固定于第一连接板件322背离显示屏31的表面。此时，第一连接板件322连接于显示屏31。本实施方式的缓冲件324的材质以及形成方式可参阅第一种实施例的缓冲件324的材质及形成方式。这里不再赘述。
可以理解的是，第一连接板件322与缓冲件324相互配合之后，面向弯折区3182设置的支撑件32的整体刚度与硬度较为适中。此时，当电子设备100处于打开状态时，支撑件32具有足够的刚度及硬度来支撑显示屏31的弯折区，从而防止显示屏31的弯折区出现塌 陷问题，也即保证显示模组30具有较佳的表面平整度。
此外，通过在第一连接板件322背离显示屏31的表面设置缓冲件324，从而进一步地提高面向显示屏31的弯折区3182设置的支撑件32的柔韧性。当电子设备100在展开或者折叠的过程中，面向弯折区3182设置的支撑件32具有较佳的柔韧性，从而避免因支撑件32的硬度及刚度较大而影响显示屏31的弯折，也即，在电子设备100的折叠过程中或者展开的过程中，缓冲件324能够吸收在弯折时所产生的应力。
此外，通过在第一连接板件322背离显示屏31的表面设置缓冲件324，从而当电子设备100处于打开状态时，转动装置40的第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压在缓冲件324上。这样，缓冲件324能够吸收部分挤压力。此时，金属部3221的通孔3225的周缘的应力不会较为集中，也即金属部3221的通孔3225的周缘挤压显示屏31的力较小，从而较大程度地防止显示屏31出现黑斑或者亮线等问题。
第三种实施例中，与第一种实施例相同的内容不再赘述。换言之，第一种实施例的大部分内容可以直接应用于第三种实施例。
请参阅图13，图13是图4所示的电子设备的显示模组在A-A线处的再一种实施方式的部分剖面示意图。支撑件32还包括第一子缓冲件3242及第二子缓冲件3243。第一子缓冲件3242固定于第一连接板件322与显示屏31之间。第二子缓冲件3243固定于第一连接板件322背离显示屏31的表面。本实施方式的第一子缓冲件3242与第二子缓冲件3243的材质与第一种实施例的缓冲件324的材质相同。这里不再赘述。
此外，因为第二子缓冲件3243固定于第一连接板件322背离显示屏31的表面，所以当电子设备100处于打开状态时，转动装置40的第二支撑板42支撑于第二子缓冲件3243。
可以理解的是，第一子缓冲件3242、第二子缓冲件3243及第一连接板件322的相互配合，此时，面向显示屏31的弯折区3182设置的支撑件32的整体刚度与硬度较为适中。当电子设备100处于打开状态时，支撑件32具有足够的刚度及硬度来支撑显示屏31的弯折区3182，从而防止显示屏31的弯折区3182出现塌陷或者凹坑的问题，也即保证显示模组30具有较佳的表面平整度。
此外，通过在第一连接板件322靠近显示屏31的表面设置第一子缓冲件3242，在第一连接板件322背离显示屏31的表面设置第二子缓冲件3243，从而显著地提高面向显示屏31的弯折区3182设置的支撑件32的柔韧性。此时，当电子设备100在展开或者折叠的过程中，面向弯折区3182设置的支撑件32具有较佳的柔韧性，从而防止显示模组30因支撑件32的硬度及刚度较大而影响显示屏31的弯折，也即，在电子设备100的折叠过程中或者展开的过程中，缓冲件324能够吸收弯折过程时所产生的应力。
此外，通过在第一连接板件322靠近显示屏31的表面设置第一子缓冲件3242，在第一连接板件322背离显示屏31的表面设置第二子缓冲件3243，从而当电子设备100处于打开状态时，转动装置40的第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压在第二子缓冲件3243。这样，因为第二子缓冲件3243具有较佳的柔韧性，所以第二子缓冲件3243具有足够的柔韧性来吸收部分挤压力。此时，金属部3221的通孔3225的周缘的应力不会较为集中，也即金属部3221的通孔3225的周缘挤压显示屏 31的力较小，从而较大程度地防止显示屏31出现黑斑或者亮线等问题。此外，当第二子缓冲件3243将部分挤压力通过第一连接板件322传递至第一子缓冲件3242，第一子缓冲件3242也能够再次吸收部分挤压力。此时，显示屏31受到较大的挤压力进一步地减少，从而较大程度地防止显示屏31出现黑斑或者亮线等问题。
此外，通过将第一子缓冲件3242覆盖有机材料部3222，也即第一子缓冲件3242覆盖了金属部3221的通孔3225，从而显著地提高了支撑件32的表面平整度以及整体性。当支撑件32受到转动装置40的挤压力时，第一连接板件322的金属部3222不容易因发生断裂而刺穿显示屏31。
一种实施方式中，第一子缓冲件3242、第二子缓冲件3243及第一连接板件322的有机材料部3222为一体成型结构。此时，第一子缓冲件3242、第二子缓冲件3243及第一连接板件322的有机材料部3222的整体性较佳，且连接牢固度也较佳。
一种实施方式中，第一子缓冲件3242、第二子缓冲件3243及第一连接板件322的有机材料部3222一次成型。
举例而言，第一子缓冲件3242、第二子缓冲件3243通过注塑与第一连接板件322连接。具体的，通过注塑工艺在金属部3221的通孔3225内注塑高分子材料。此外，高分子材料可以溢出通孔3225，并流向第一金属板件321与第二金属板件323之间。当高分子材料冷却固化后，高分子材料将一次形成有机材料部3222、第一子缓冲件3242和第二子缓冲件3243。
在本实施方式中，通过将第一子缓冲件3242、第二子缓冲件3243及第一连接板件322的有机材料部3222一次成型，可以简化支撑件32的加工工艺，从而减少支撑件32的成本投入。
在其他实施方式中，第一子缓冲件3242与第二子缓冲件3243的形成方式也可参阅第一种实施方式的缓冲件324的其他形成方式。例如，通过紫外固化方式或者热固化方式形成，或者第一子缓冲件3242与第二子缓冲件3243的材质也可以为金属。具体的这里不再赘述。
上述通过相关附图介绍了显示模组30的三种结构的实施例。在这三种实施例中，在Z方向上，第一连接板件322的高度H1小于第一金属板件321的高度H2以及第二金属板件323的高度H3。这样，通过在第一连接板件322上可以设置缓冲件324，以进一步地提高支撑件32的柔韧性。下文将通过相关附图介绍显示模组30的第四种实施例：在Z方向上，第一连接板件322的高度H1等于第一金属板件321的高度H2以及第二金属板件323的高度H3。这样，在本实施例中第一连接板件322不再额外设置缓冲件324，可以简化显示模组30的结构复杂性。
第四种实施例中，与第一种实施例相同的内容不再赘述。换言之，第一种实施例的大部分内容可以直接应用于第四种实施例。
请参阅图14，图14是图4所示的电子设备的显示模组在A-A线处的再一种实施方式的部分剖面示意图。在Z方向上，第一连接板件322的高度H1均等于第一金属板件321的高度H2以及第二金属板件323的高度H3。
可以理解的是，金属部3221的硬度及刚度大于有机材料部3222的刚度及硬度。此时，因为第一连接板件322同时具有金属部3221及有机材料部3222，所以第一连接板件322的整体刚度及硬度较为适中。当电子设备100处于打开状态时，第一连接板件322具有足够的刚度及硬度来支撑显示屏31的弯折区3182，以防止显示屏31的弯折区3182出现塌陷或者凹坑的问题，也即保证显示模组30具有较佳的表面平整度。当电子设备100在展开或者折叠的过程中，因为第一连接板件322具有较佳的柔韧性来发生弯折，所以第一连接板件322影响显示屏31的弯折较小。换言之，在电子设备100的折叠过程中或者展开的过程中，有机材料部3222能够吸收金属部3221在弯折时所产生的应力，此时，第一连接板件322对显示屏31的弯折的影响较小。
此外，通过将有机材料部3222设置在金属部3221的通孔3225内，从而提高第一连接板件322的柔韧性，此时，当转动装置40的第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压第一连接板件322时，有机材料部3222具有足够的柔韧性来吸收部分挤压力，从而防止通孔3225的周缘的应力过于集中，也即防止光学胶39因过度挤压而发生凸出，进而避免显示屏31出现黑斑或者亮线等问题。
此外，通过在金属部3221的通孔3225内设置有机材料部3222，从而使得金属部3221与有机材料部3222形成一体结构，也即第一连接板件322的整体性较佳。此时，金属部3221与有机材料部3222的连接牢固度较佳。故而，当第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压第一连接板件322时，因为金属部3221与有机材料部3222的连接牢固度较佳，所以金属部3221不容易因发生断裂而刺穿或者挤压显示屏21。
一种实施方式中，有机材料部3222朝向显示屏31的表面与金属部3221的第一面3223齐平。此时，有机材料部3222占满通孔3225。这样，第一连接板件322的表面的平整度也较佳，也即通孔3225的周缘通过有机材料部3222连接。当第一支撑板41、第二支撑板42及第三支撑板43上的凹槽或者通孔的周缘挤压第一连接板件322时，金属部3221的通孔3225的周缘不再能够挤压显示屏31，从而防止显示屏31出现黑斑或者亮线等问题。
在其他实施例中，请参阅图15，图15是图4所示的电子设备的显示模组在A-A线处的再一种实施方式的部分剖面示意图。支撑件32还包括面向显示屏31的弯折区3182的第三金属板件3251及第二连接板件3252。此外，第一金属板件321、第二连接板件3252、第三金属板件3251、第一连接板件322以及第二金属板件323依次连接。
此外，在Z方向上，第二连接板件3252的高度均等于第一金属板件321的高度H2(请参阅图14)以及第二金属板件323的高度H3(请参阅图14)。
第二连接板件3252也包括金属部3221以及位于通孔3225的有机材料部3222。有机材料部3222固接于金属部3221。
可以理解的是，本实施方式的通孔3225的设置方式可参阅第一种实施例中第一连接板件322的通孔3225的设置方式。这里不再赘述。本实施方式的金属部3221的材质及设置方式也可参阅第一种实施例中第一连接板件322的金属部3221的材质及设置方式。这里不再赘述。本实施方式的有机材料部3222的材质及设置方式可参阅第一种实施例中第一连接板件322的有机材料部3222的材质及设置方式。这里不再赘述。
在本实施方式中，通过额外设置第二连接板件3252，从而增加支撑件32的柔韧性较佳的区域，进而在支撑件32固定于显示屏31时，第二连接板件3252可以固定于显示屏31的弯折区3182中弯曲角度较大的区域，以保证显示屏31的弯折区3182具有较佳的弯折效果。
在其他实施方式中，支撑件32还可以包括第四金属板件、第五金属板件、……、第S金属板件。S为大于等于六的整数。此外，支撑件32还可以包括第三连接板件、第四连接板件、……、第P连接板件。P为大于等于五的整数。第P连接板连接两个金属板件之间。第P连接板件设有通孔3225。且第P连接板件包括金属部3221及位于通孔3225的有机材料部3222。有机材料部3222固接于金属部3221。具体的，本实施方式不再赘述。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
