下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的折叠式电子设备进行详细地说明。
请参考图1至图52，本申请实施例公开一种折叠式电子设备，所公开的折叠式电子设备包括框体、铰链机构200和柔性屏幕300。
框体包括第一壳体110和第二壳体120，第一壳体110和第二壳体120通过铰链机构200转动连接，以使折叠式电子设备具有展开状态和折叠状态。可选地，铰链机构200包括底座210、屏幕支撑侧板和转动臂，底座210为铰链机构200的其他组成部件提供安装基础，屏幕支撑侧板通过转动臂与底座210转动连接。第一壳体110和第二壳体120可通过屏幕支撑侧板与底座210转动连接，从而实现第一壳体110和第二壳体120的相对转动。
在一种可选的实施例中，屏幕支撑侧板的数量为两个，分别包括第一屏幕支撑侧板220和第二屏幕支撑侧板230，第一屏幕支撑侧板220和第二屏幕支撑侧板230分别位于底座210的两侧，第一屏幕支撑侧板220与第一壳体110相对应，第二屏幕支撑侧板230与第二壳体120相对应。转动臂包括 第一转动臂240和第二转动臂250，第一屏幕支撑侧板220通过第一转动臂240与底座210转动连接，第二屏幕支撑侧板230通过第二转动臂250与底座210转动连接。当然，铰链机构200的具体结构为现有技术，本文不作赘述。
柔性屏幕300设置于框体，可选地，柔性屏幕300设置于第一壳体110和第二壳体120上。此时柔性屏幕300随着第一壳体110和第二壳体120相对转动位置的不同，以实现折叠式电子设备的展开和折叠。
本申请公开的折叠式电子设备可以为外折式电子设备，也可以为内折式电子设备。例如，折叠式电子设备可以为外折式电子设备。当折叠式电子设备处于折叠状态时，折叠式电子设备的体积较小，此时折叠式电子设备可以仅使用第一壳体110或第二壳体120上的屏幕区域。此时电子设备的正反两面均为两个独立的显示区域。当折叠式电子设备处于展开状态时，电子设备的体积增大，第一壳体110上的柔性屏幕300的显示区域和第二壳体120上的柔性屏幕300的显示区域形成一个面积较大的整体显示区域，使得电子设备的显示面积也成倍增加。这里的折叠式电子设备仅设置有一个能够折叠的柔性屏幕300。
再例如，折叠式电子设备可以为内折式电子设备。此时当折叠式电子设备处于折叠状态时，柔性屏幕300被折叠在框体内，因此需要在第一壳体110或第二壳体120背离柔性屏幕300的一侧额外设置一个显示屏，在电子设备处于折叠状态的情况下，可以使用额外设置的显示屏进行显示操作。
本申请公开的折叠式电子设备还包括支撑件400和粘接件500，支撑件400位于柔性屏幕300与铰链机构200之间，支撑件400的至少部分与柔性屏幕300的折弯区域310相对设置，此时支撑件400的至少部分可以覆盖折弯区域310。柔性屏幕300和铰链机构200中的一者通过粘接件500与支撑件400粘接。此时支撑件400仅能够粘接在其中一者上，不能同时粘接在柔性屏幕300和铰链机构200上。
具体的操作过程中，支撑件400可在铰链机构200的作用下，其局部或整体跟随柔性屏幕300一同弯折或展开，从而与折弯区域310动态匹配。
可选地，支撑件400可以为板状结构，也可以为层状或片状结构。支撑件400的具体形状本文不作限制。支撑件400可以为钢片或者可弯折的塑胶结构，当然支撑件400还可以采用其他材料制作，对于支撑件400的具体制 作材料本文不作限制。
本申请公开的实施例中，支撑件400能够将铰链机构200与折弯区域310分隔开，从而能够避免铰链机构200与柔性屏幕300发生干涉的风险，故而使得柔性屏幕300损坏的风险较小，从而提高了折叠式电子设备的安全性和可靠性。
另外，支撑件400还能够覆盖铰链机构200上的孔、洞区域，从而提高了柔性屏幕300的支撑可靠性，避免柔性屏幕300局部发生凹陷。此外支撑件400覆盖铰链机构200上的孔、洞区域，能够避免折叠式电子设备整机跌落磕碰伤导致主屏进气失效的风险。
本申请公开的实施例中，支撑件400设置于折弯区域310与铰链机构200之间，能够弱化铰链机构200的底座210及屏幕支撑侧板之间不平整带来的影响，最大可能性的保证折痕均匀一致性。
进一步地，折叠式电子设备还可以包括第一填充层410和第二填充层430，第一填充层410可以贴设于支撑件400朝向柔性屏幕300一侧的表面，第二填充层430可以贴设于支撑件400朝向铰链机构200一侧的表面。
此方案中，支撑件400的两侧均铺设有填充层，从而阻隔支撑件400与铰链机构200的金属结构直接发生剐蹭，以及阻隔支撑件400与柔性屏幕300的保护膜直接剐蹭，从而能够减小折叠式电子设备由于剐蹭造成的异响。另外，支撑件400的两侧均铺设有填充层，还能够避免铰链机构200的润滑油脂溢流至支撑件400与柔性屏幕300的保护膜之间，故而还能够避免折叠式电子设备的溢油异响。因此本申请公开的折叠式电子设备能够进一步降低其在折叠状态和展开状态切换过程中的异响。
另外，填充层用于填充支撑件400与柔性屏幕300以及支撑件400与铰链机构200之间的间隙，从而起到提升落球可靠性性能以及支撑柔性屏幕300下凹的作用，以减轻柔性屏幕300的折痕的凹陷程度，故而提高了折叠式电子设备的显示性能。
可选地，第一填充层410或第二填充层430开设有通孔，通孔外露支撑件400的部分表面，粘接件500的至少部分可以位于通孔内，从而使得柔性屏幕300或铰链机构200通过粘接件500直接与支撑件400粘接。或者，柔性屏幕300可以通过粘接件500与第一填充层410粘接，再或者，铰链机构200可以通过粘接件500与第二填充层430粘接。此时柔性屏幕300和铰链 机构200通过第一填充层410和第二填充层430间接与支撑件400粘接。
上述实施例中，支撑件400可以采用厚度为0.01mm的手撕钢片，为了保证支撑件400的刚度，支撑件400可以采用3层厚度为0.01mm的手撕钢片叠置而成，当然支撑件400的厚度可以根据实际工况灵活选择，本文不作限制。粘接件500可以为双面胶、胶水等粘接结构，当然粘接件500还可以为其他粘接结构，本文不作限制。
在另一种可选的方案中，如图1至7所示，支撑件400通过粘接件500可以与折弯区域310粘接。此方案中，支撑件400不容易与柔性屏幕300的保护膜发生相对位移，因此可以杜绝支撑件400与柔性屏幕300的保护膜之间发生摩擦异响的问题，同时也可以规避支撑件400与柔性屏幕300的保护膜之间的吸附异响问题。因此能够进一步降低折叠式电子设备的异响，从而进一步提升折叠式电子设备的用户体验。
此外，由于支撑件400与折弯区域310粘接在一起，因此支撑件400与柔性屏幕300为一体式结构，因此支撑件400与柔性屏幕300之间不容易发生相对位置，因此折叠式电子设备在整机跌落时，不容易受到铰链机构200搓动的影响造成支撑件400撕裂的风险，因此提高了支撑件400的安全性和可靠性。
进一步地，支撑件400的中部区域可以通过粘接件500与折弯区域310的中部区域粘接。这里的中部区域是指在折弯区域310上靠近折弯区域310中心位置的区域，也可以理解为靠近折弯区域310的折弯中心轴线的区域。折弯区域310关于折弯中心轴线对称，这里折弯中心轴线也可以理解为铰链机构200的转动中心轴线，还可以理解为折弯区域310的中心线。以折弯区域310的中心线为基准，中心线的两侧且折弯区域310内的一定范围内，界定出与中心线相平行的第一边界线和第二边界线，中心线位于第一边界线和第二边界线之间。第一边界线与中心线之间的距离为第一距离，第二边界线与中心线之间的区域为第二距离，第一距离与第二距离之间的比值可以为1比0.8，或为0.8比1，此时第一边界线和第二边界线之间在折弯区域310上界定的区域即为折弯区域310的中部区域。当然支撑件400的中部区域也可以采用上述方式界定，本文不再赘述。
此方案中，粘接件500既位于支撑件400的中部区域，又位于折弯区域310的中部区域。支撑件400通过粘接件500与折弯区域310的中部区域粘 接，折弯区域310在折弯后，其底部呈水滴状，因此其中部区域可近似为平面，因此将支撑件400粘接在中部区域，其折弯与展开过程中粘接区域422a的形变较小，因此其粘接性能更好，粘接更加牢固。
另外，支撑件400的中部区域可以通过粘接件500与折弯区域310粘接，支撑件400向折弯区域310的两侧延伸的距离基本相同，因此支撑件400对折弯区域310的支撑力更加均衡，支撑效果更好。
进一步地，在折叠式电子设备还包括第一填充层410和第二填充层430的情况下，支撑件400的中部区域通过第一填充层410和粘接件500与折弯区域310的中部区域粘接。这里的支撑件400的中部区域可以理解为第一填充层410的中部区域。
上述实施例中，第一填充层410和第二填充层430均可以采用泡棉等材料制作，或者，第一填充层410可以为泡棉，第二填充层430可以为高温胶纸，当然第一填充层410和第二填充层430还可以为其他材料本文不作限制。
在另一种可选的实施例中，粘接件500可以具有相背设置的第一粘接面和第二粘接面，第二粘接面可以为网格粘接面，第一粘接面朝向第一填充层410，第二粘接面可以朝向折弯区域310。此方案中，网格粘接面朝向柔性屏幕300的保护膜，既满足粘接牢固的要求，又能够实现重复可拆卸，因此避免粘接件500拉扯坏柔性屏幕300的保护膜。
在另一种可选的实施例中，如图1和图8所示，粘接件500可以为长条形结构，粘接件500的延伸方向与折弯区域310的中心线的延伸方向可以相同。此方案既能够使得支撑件400与折弯区域310粘接牢固，又能够尽量避免由于粘接件500拉扯柔性屏幕300而产生似粘非粘的异响。
在另一种可选的实施例中，在折叠式电子设备处于展开状态下，也就是铰链机构200、柔性屏幕300和支撑件400均处于展平位置，粘接件500的正投影可以位于第一填充层410的正投影内，第一填充层410的正投影可以位于支撑件400的正投影内。
此方案中，粘接件500不会凸出于第一填充层410和支撑件400，因此避免造成粘接件500与铰接机构发生粘连的风险。
进一步地，在折叠式电子设备处于展开状态下，支撑件400的正投影可以位于第二填充层430的正投影内。此方案中，支撑件400向第二填充层430内缩，也就是说支撑件400的边缘不凸出于第二填充层430的边缘，从而避 免支撑件400在折叠或展开过程中与铰链机构200发生摩擦的风险，进一步提高了折叠式电子设备的可靠性。
在一种可选的实施例中，在折叠式电子设备处于展开状态下，支撑件400的边缘与第二填充层430的边缘之间的距离可以大于或等于3mm，也就是说，第二填充层430的边缘凸出支撑件400的边缘距离可以大于或等于3mm。当然，支撑件400的边缘与第二填充层430的边缘之间的距离还可以为其他数值，本文不作限制。
相关技术中，为了减少转动臂与屏幕支撑侧板之间的高度差，屏幕支撑侧板开设有连接槽，转动臂的部分位于连接槽内。然而，折叠式电子设备在展开状态和折叠状态切换时，支撑件400的边缘会发生滑移，从而容易使得支撑件400的边缘插入连接槽内，故而使得支撑件400被拉扯发生变形或断裂。
基于此，在另一种可选的实施例中，支撑件400的边缘可以开设有避位豁口；避位豁口可以与连接槽相对设置。
在一种可选的实施例中，支撑件400相背的两侧边缘分别可以开设有第一避位豁口403和第二避位豁口404。第一屏幕支撑侧板220可以开设有第一连接槽221，第一转动臂240的部分可以位于第一连接槽221内，第一避位豁口403可以与第一连接槽221相对设置。
第二屏幕支撑侧板230可以开设有第二连接槽231，第二转动臂250的部分可以位于第二连接槽231内，第二避位豁口404可以与第二连接槽231相对设置。
此方案中，避位豁口对连接槽进行避位，从而使得支撑件400与连接槽相对的位置设置较大的内缩，从而使得折叠式电子设备在展开状态和折叠状态切换时，支撑件400的边缘不容易插入连接槽内，进而使得支撑件400不容易与铰链机构200发生干涉，从而进一步提高了折叠式电子设备的安全性和可靠性。
上述实施例中，在折叠式电子设备包括第一填充层410和第二填充层430的情况下，由于第一填充层410的正投影小于支撑件400的正投影，因此第一填充层410不容易插入连接槽，故而仅需要在第二填充层430和支撑件400的对应位置开设避位豁口。
本申请公开的第一种折叠式电子设备如图1至图7所示，支撑件400的 中部区域通过第一填充层410和粘接件500与折弯区域310的中部区域粘接。图8至图10为本申请公开的第一种折叠式电子设备中支撑件400、第一填充层410和第二填充的结构示意图。
本申请公开的实施例中支撑件400可以与铰链机构200连接，在一种可选的实施例中，支撑件400可以与第一屏幕支撑侧板220或第二屏幕支撑侧板230相连接，也就是说，支撑件400一侧固定在第一屏幕支撑侧板220或第二屏幕支撑侧板230上，另一侧为活动侧。此时，折叠式电子设备在折叠状态和展开状态切换时，支撑件400的滑动距离较大，因此折叠式电子设备的异响较大。
基于此，本申请还公开了第二种折叠式电子设备，如图11至图15所示，支撑件400的表面开设有分割裂缝421，分割裂缝421可以将支撑件400分隔出相对活动连接的固定部422和弯折部423，固定部422可以通过粘接件500固定粘接于铰链机构200的底座210。如图52所示，固定部422可以通过粘接件500固定粘接于C1、C2、C3、C4和C5中的至少一个或多个区域内。折叠式电子设备在折叠和状态切换的过程中，底座210的位置始终不变，因此底座210相对固定，故而将固定部422粘接在底座210上。折叠式电子设备在折叠状态和展开状态切换的过程中，弯折部423可随柔性屏幕300的折弯区域310弯折。
在具体的操作过程中，固定部422通过粘接件500与底座210进行粘接，因此折叠式电子设备在折叠状态和展开状态切换的过程中，固定部422的一端始终相对于底座210固定，弯折部423在铰链机构200的作用下随着屏幕折弯或展平。同时，固定部422的一端还与折弯部连接，因此固定部422将弯折部423拉住，从而避免弯折部423在弯折的过程中发生跑偏的现象。
此方案中，支撑件400的固定部422固定在底座210上，底座210位于第一屏幕支撑侧板220和第二屏幕支撑侧板230之间，因此支撑件400固定在铰链机构200的中间区域上。支撑件400的固定部422固定在底座210的方案相比于支撑件400单侧粘接屏幕支撑侧板方案来说，支撑件400的滑动距离和滑动速率缩减为原来的一半，因此支撑件400的固定部422与底座210粘接固定可以将支撑件400的位移缩减一半，故而相应的速率也会缩减一半，因此会进一步降低折叠式电子设备的异响。
在一种可选的实施例中，固定部422可以包括并列设置的粘接区域422a 和连接区域422b，粘接区域422a通过连接区域422b与弯折部423相连接，粘接区域422a可以通过粘接件500与底座210粘接。这里的连接区域422b可以理解为弹性臂，连接区域422b可以作为固定部422的弯折端，从而实现粘接区域422a与弯折部423的可相对活动连接。也可以理解为，固定部422的部分表面通过粘接件500与底座210粘接，粘接件500与弯折部423之间的区域即为连接区域422b，由于弯折部423与连接区域422b之间也具有分割裂缝421，因此弯折部423与连接区域422b之间能够发生弹性形变，故而使得折叠式电子设备在折叠状态和展开状态切换的过程中，弯折部423对连接区域422b的拉扯力较小，故而使得支撑件400与底座210的粘接可靠性较高。
另外，本申请中的支撑件400的固定部422的具有较长的弹性臂，因此可容纳铰链机构200更多的变形，故而能够大大改善支撑件400撕扯的问题，因此能够进一步提高支撑件400的可靠性和安全性。
在一种可选的实施例中，如图17至图20所示，固定部422可以为条形结构，条形结构的一端为自由端，另一端为连接端，连接端与弯折部423连接，此时粘接区域422a为固定部422靠近自由端的一侧的区域，而连接区域422b为固定部422靠近连接端一侧的区域。
在另一种可选的实施例中，如图23至图25所示，固定部422可以为十字形结构，十字形结构的其中相对的两端可以为连接端，另外相对的两端可以为自由端。粘接件500靠近自由端设置。
在另一种可选的实施例中，如图26至图28所示，连接区域422b可以为弹性结构，例如，连接区域422b可以为弹簧、或者网状结构。在弹性结构的作用下，活动部与弯折部423可以加大连接距离，从而大幅减轻连接区域422b对粘接区域422a的拉扯破坏，进而进一步提高了支撑件400的安全性和可靠性。
当然，固定部422还可以采用如图29至图37所示的方案中的结构，本申请仅公开了几种可行的方案不用于限定固定部422的具体结构，只要能够实现固定部422与弯折部423相对活动结构，均属于本申请的保护范围。
在另一种可选的实施例中，如图20所示，折叠式电子设备还可以包括第一填充层410和第二填充层430，第一填充层410可以覆盖支撑件400朝向柔性屏幕300的一侧的表面，且第一填充层410贴设于弯折部423。此时第 一填充层410覆盖固定部422，由于第一填充层410贴于弯折部423上，因此第一填充层410也相对于固定部422活动。
固定部422上可以设置有粘接件500，弯折部423朝向铰链机构200的一侧的表面上可以设置有第二填充层430。
此方案中，支撑件400的两侧均铺设有填充层，从而阻隔支撑件400与铰链机构200的金属结构直接发生剐蹭，以及阻隔支撑件400与柔性屏幕300的保护膜直接剐蹭，从而能够减小折叠式电子设备由于剐蹭造成的异响。另外，支撑件400的两侧均铺设有填充层，还能够避免铰链机构200的润滑油脂溢流至支撑件400与柔性屏幕300的保护膜之间，故而还能够避免折叠式电子设备的溢油异响。因此本申请公开的折叠式电子设备能够进一步降低其在折叠状态和展开状态切换过程中的异响。
另外，填充层用于填充支撑件400与柔性屏幕300以及支撑件400与铰链机构200之间的间隙，从而起到提升落球可靠性性能以及支撑柔性屏幕300下凹的作用，以减轻柔性屏幕300的折痕的凹陷程度，故而提高了折叠式电子设备的使用性能。
上述实施例中，为了避免支撑件400与第二填充层430之间存在较大的间隙，第二填充层430的厚度略小于粘接件500的厚度，或者第二填充层430的厚度与粘接件500的厚度相等。
上述实施例中，固定部422的连接区域422b悬空设置，因此容易造成损坏，为此，在另一种可选的实施例中，折叠式电子设备还可以包括第三填充层440，第三填充层440与第二填充层430可以并列设置，第三填充层440可以粘接于连接区域422b朝向底座210的一侧，第二填充层430和第三填充层440之间可以具有分隔间隙。
此方案中，第三填充层440能够对连接区域422b进行支撑，从而避免连接区域422b悬空，进一步避免了固定部422被损坏的风险，因此进一步提高了支撑件400的可靠性和安全性。另外，第二填充层430和第三填充层440之间预留分隔间隙，从而避免弯折部423在弯折的过程中造成第二填充层430和第三填充层440发生相互挤压的风险。
这里的第一填充层410、第二填充层430和第三填充层440均可以为泡棉，当然还可以为其他材料，本文不作限制。
如图20和图22所示，第二填充层430可以包括多个部分，第二填充层 430的多个部分需要预留出固定部422的外露区域，从而使得固定部422通过外露区域外露出来。第二填充层430的具体结构可以根据实际工况灵活选择，本文附图20和附图22仅公开一种可行的结构，不用于限定第二填充层430的具体结构。
上述实施例中，由于第一填充层410铺设在支撑件400的表面上，因此固定部422容易粘连在第一填充层410上，以使的第一填充层410破坏固定部422与底座210之间的粘接结构。为此，在另一种可选的实施例中，折叠式电子设备还可以包括隔离层450，隔离层450可以设置于第一填充层410与支撑件400之间，且固定部422的至少部分可以与隔离层450相对设置。此方案中，隔离层450能够避免固定部422粘接在第一填充层410上，从而不容易破坏固定部422与底座210之间的粘接结构，因此进一步提高了折叠式电子设备的可靠性和安全性。
可选地，隔离层450可以采用泡棉、塑胶、手撕钢等材料制作，当然隔离层450还可以采用其他材料制作，本文不作限制。
需要注意的时，这里的隔离层450设置于固定部422与第一填充层410之间，其不能与固定部422发生粘接，其仅起到隔离第一填充层410和固定部422的作用。
在另一种可选的实施例中，弯折部423的表面面积可以大于固定部422的表面面积。此方案中，弯折部423的表面面积更大，从而使得对柔性屏幕300的折弯区域310的支撑效果更好。
在另一种可选的实施例中，固定部422的数量可以为至少两个，至少两个固定部422沿铰链机构200的转动轴线的延伸方向间隔设置。此方案中固定部422的数量为多个，因此能够增大支撑件400与底座210的粘接面积，故而提高了支撑件400与底座210的粘接可靠性。
可选地，至少两个固定部422可以对称设置，这里的对称设置可以是中心对称，也可以为轴对称。此时，至少两个固定部422的粘接面积相同，因此受力更加均衡。
本申请还公开了第三种折叠式电子设备，如图38至图41所示，在一种可选的实施例中，支撑件400的数量可以至少为两个，分别可以包括第一支撑件401和第二支撑件402。粘接件500可以包括第一粘接层510和第二粘接层520。
第一支撑件401可以通过第一粘接层510与第一屏幕支撑侧板220粘接，如图52所示，第一支撑件401可以通过第一粘接层510粘接与A区域。且第一支撑件401覆盖部分底座210。此时，第一支撑件401的部分延伸至底座210的上方。第二支撑件402可以通过第二粘接层520与第二屏幕支撑侧板230粘接，如图52所示，第二支撑件402可以通过第二粘接层520粘接与B区域。且第二支撑件402覆盖部分底座210。此时，第二支撑件402的部分延伸至底座210的上方。第一支撑件401和第二支撑件402之间可以设置有间隔间隙610。
此时，第一支撑件401和第二支撑件402之间设置有间隔间隙610，因此第一支撑件401和第二支撑件402完全断开，有助于支撑件400一侧固定跟随铰链机构200进行弯折，而未固定的一侧容易绕铰链机构200的中间区域折弯。
此方案相比于单个支撑件400单侧固定的方式来说，第一支撑件401和第二支撑件402可以将位移缩减为原来的一半，故而相应的速率也会缩减一半，因此会进一步降低折叠式电子设备的异响。另外，第一支撑件401和第二支撑件402之间的间隔间隙610与底座210相对，而底座210与折弯区域310相对，因此柔性屏幕300在折叠的过程中，间隔间隙610可以对折弯区域310进行避让，从而减小对折弯区域310的作用力，降低折弯区域310的损坏风险。
上述实施例中，屏幕支撑侧板与底座210之间具有一定的间隙，折叠式电子设备在折叠状态和展开状态切换的过程中，支撑件400容易插入到底座210的下方。
基于此，在另一种可选的实施例中，第一支撑件401朝向第二支撑件402的一侧可以设置有凸起部4011，第二支撑件402朝向第一支撑件401的一侧开设有配合豁口4021，凸起部4011的至少部分可以位于配合豁口4021内。
此方案中，支撑件400设置有凸起部4011，在折叠式电子设备处于折叠状态下，凸起部4011还可以搭接在底座210上，因此能够避免支撑件400在动态折弯的过程中插入底座210的下方，因此能够进一步提高折叠式电子设备的安全性和可靠性。
可选地，凸起部4011可以开设与第一支撑件401的中部区域，当然还可以开设于其他区域，本文不作限制。
在另一种可选的实施例中，第一支撑件401和第二支撑件402朝向柔性屏幕300的一侧表面可以均贴设有相应的第一填充层410，第一支撑件401和第二支撑件402朝向其对应的屏幕支撑侧板的一侧可以均贴设有相应的第二填充层430。第一屏幕支撑侧板220通过第一粘接层510与第一支撑件401相对应的第二填充层430粘接。第二屏幕支撑侧板230通过第二粘接层520与第二支撑件402相对应的第二填充层430粘接。
此处的第一填充层410和第二填充层430的作用与上述实施例中的第一填充层410和第二填充层430的作用相同，本文不再赘述。
上述实施例中，屏幕支撑侧板的形变区容易发生形变，从使得支撑件400边缘凸起，进而容易造成支撑件400与柔性屏幕300发生摩擦异响。
基于此，在另一种可选的实施例中，第一支撑件401上设置的第一填充层410背离第二支撑件402的一侧可以设置有第一避让豁口411，第一避让豁口411可以与第一屏幕支撑侧板220的形变区相对设置。
第二支撑件402上设置的第一填充层410背离第一支撑件401的一侧可以设置有第二避让豁口412，第二避让豁口412与第二屏幕支撑侧板230的形变区相对设置。
此方案中，第一填充层410上开设避让豁口能够避开屏幕支撑侧板的形变区，从而不容易使得支撑件400发生翘曲，进而不容易造成支撑件400与柔性屏幕300发生摩擦异响。
可选地，屏幕支撑侧板尤其在中间和两侧位置容易发生变形凸起，因此避让豁口开设于第一支撑件401和第二支撑件402的中间和两侧位置上。
为了提高屏幕支撑侧板与支撑件400的粘接强度，在另一种可选的实施例中，如图46所示，第一粘接层510和第二粘接层520均可以开设有点胶槽530，第一粘接层510和第二粘接层520上的点胶槽530均贯穿其粘接面。此方案中，屏幕支撑侧板与支撑件400采用点胶加粘胶的双重固定形式，从而保证了支撑件400折弯过程中不容易发生相对位移，从而进一步提高了支撑件400粘接可靠性。
如图46所示，第一粘接层510和第二粘接层520均包括并列设置的第一粘接部和第二粘接部，第一粘接部和第二粘接部可以均为双面胶，第一粘接部设置有豁口，第二粘接部靠近豁口设置，从而使得第一粘接部和第二粘接部围成点胶槽530。当然第一粘接层510和第二粘接层520还可以为其他结 构，本文不作限制。需要注意的是，点胶槽530需要预留点胶泄流口，从而便于点胶的过程中排除内部空气，提高点胶的可靠性。
本申请还公开的第四种折叠式电子设备如图48至图51所示，在一种可选的实施例中，粘接件500可以包括第一粘接层510和第二粘接层520。支撑件400可以包括依次连接的第一区域405、伸缩区域406和第二区域407，第一区域405可以通过第一粘接层510与第一屏幕支撑侧板220粘接。如图52所示，第一区域405的至少部分可以通过第一粘接层510粘接与A区域。第二区域407可以通过第二粘接层520与第二屏幕支撑侧板230粘接。如图52所示，第二区域407的至少部分可以通过第二粘接层520粘接与B区域。伸缩区域406的至少部分可以与折弯区域310相对设置。
具体，支撑件400的两侧在固定的情况下，伸缩区域406跟随着铰链机构200进行拉伸，支撑件400在铰链机构200与柔性屏幕300的共同作用下，形成包裹折弯区域310的水滴状。
此方案中，在铰链机构200折叠过程中，支撑件400的伸缩区域406能够进行拉伸弯折，从而使得支撑件400与屏幕支撑侧板的粘接位置受到的拉扯力较小，故而不容易造成支撑件400从屏幕支撑侧板上脱落，从而提高了折叠式电子设备的可靠性和安全性。另外，本方案中的结构也使得折叠式电子设备的异响较小。
上述实施例中，伸缩区域406可以为网状结构。此时可以通过对支撑件400的刻蚀以得到网状结构，因此使得支撑件400的制作工艺简单，成本较低。
在另一种可选的实施例中，伸缩区域406还可以为弹性结构，例如弹簧结构，当然伸缩区域406还可以为其他结构，本文不作限制。
上述实施例中，第一区域405和第二区域407可以对应设置有第一填充层410和第二填充层430。或者第一填充层410和第二填充层430覆盖支撑件400的相背的两侧表面，第一填充层410和第二填充层430与伸缩区域406相对应的区域也设置有对应伸缩结构，因此第一填充层410和第二填充层430也可以蚀刻有网状结构。
在折叠式电子设备包括第一填充层410和第二填充层430的情况下，第一填充层410、支撑件400和第二填充层430均可以设置有定位部460，从而便于第一填充层410、支撑件400和第二填充层430定位装配，提高第一填 充层410、支撑件400和第二填充层430的装配精度。
可选地，定位部460可以为定位孔，第一填充层410的定位孔、支撑件400的定位孔和第二填充层430的定位孔相对设置，从而对第一填充层410、支撑件400和第二填充层430的装配位置进行定位。或者，定位部460还可以为标识部，例如，圆形标识，十字形标识等结构，通过对应的标识部之间对应，从而对第一填充层410、支撑件400和第二填充层430的装配位置进行定位。
本申请实施例公开的电子设备可以是智能手机、平板电脑、电子书阅读器、可穿戴设备(例如智能手表)、电子游戏机等设备，本申请实施例不限制电子设备的具体种类。
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。
