下面结合附图，对本申请实施例进行详细说明。在不冲突的情况下，下述的实施例中的特征可以相互组合。
如图1所示，本申请涉及一种电子设备10。该电子设备10为可折叠的电子设备10，其可以为手机、电脑、平板、电子书等装置。电子设备10可以为LCD电子设备，当然，也可以为OLED电子设备。
电子设备10包括机壳100、支撑板200和显示面板300。
其中，机壳100的表面向内凹陷形成避空110，避空110沿第一方向Y贯穿机壳100。支撑板200设置于机壳100的上方，其个数至少为两个，相邻的两个支撑板200形成支 撑主体210。显示面板300用于实现电子设备10的智能显示，支撑板200配置为支撑显示面板300，即显示面板300固定于支撑板200的上方。在一实施例中，支撑板200可以至少部分与机壳卡扣连接，在另一实施例中，支撑板至少可通过胶粘与机壳部分连接，本申请对此不作具体限定。
当电子设备10为LCD电子设备时，显示面板300为液晶面板，液晶面板包括上基板(未图示)和下基板(未图示)以及位于上基板与下基板之间的液晶层(未图示)。液晶层被上基板与下基板之间产生的电场驱动，以控制图像的显示。
当电子设备10为OLED电子设备时，显示面板300至少包括有机发光二极管(未图示)，有机发光二极管包括阳极、阴极以及位于阳极与阴极之间的有机发光层。在有机发光二极管中，分别来自阳极的空穴和阴极的电子迁移至有机发光层，使得从有机发光层发射光，以显示图像。
在一实施例中，如图2和图3所示，支撑板的数量为两个，显示面板300可在折叠位置11和展平位置12之间切换。当显示面板300自展平位置12切换至折叠位置11时，支撑主体210中的两个支撑板200相对转动，从而使得显示面板300发生弯折，特别是位于两个支撑板200的邻接位置上方的显示面板300发生弯折。两个支撑板200的部分进入避空110，从而带动显示面板300的部分也进入避空110。当显示面板300位于折叠位置11时，支撑主体210中的两个支撑板200被显示面板300所间隔。
需要说明的是，为了清晰地表示各个零部件，在显示面板300和机壳100中绘示有斜线段，该斜线段不表示为剖面线。
将显示面板300位于展平位置12时所处的表面作为基准面。当显示面板300位于折叠位置11时，显示面板300的产生弯折的位置的最低点310低于基准面。
在一些设计中，如图4所示，机壳中没有设置避空，仅采用改变多个支撑板1连接形成的整体的尺寸的方式，以避免显示面板2发生堆叠的情况。在这种设计中，多个支撑板1连接形成链式结构，多个支撑板1的整体尺寸大于显示面板2的尺寸。当要使显示面板2位于折叠位置时，改变相邻的支撑板1的相对位置，从而使得显示面板2跟随支撑板1的运动而运动。在此过程中，部分支撑板1转动，并使得多个支撑板1连接形成的整体向下凹陷，显示面板2跟随支撑板1向下凹陷。由于多个支撑板1连接形成的整体的尺寸大于显示面板2的尺寸，从而使得在折叠位置时，显示面板2可以完全贴合于支撑板1，避免显示面板2出现堆叠的现象。然而，当显示面板2位于展平位置时， 由于多个支撑板1连接形成的整体的尺寸大于显示面板2的尺寸，部分相邻的支撑板1之间存在夹角，即部分支撑板1的一端相对于另一端远离显示面板2，从而使得显示面板2可以撑平，同时，避免显示面板受到拉伸力而发生形变。但是，这样的设置，使得当显示面板2位于展平位置时，显示面板2的各个位置无法均贴合于支撑板1，进而造成显示面板2和支撑板1之间存在间隙，显示面板2的表面不平整、容易受损等情况。
本设计中，如图1-图3所示，通过设置避空110，可对部分弯折后的显示面板300进行容纳，从而避免当显示面板300位于折叠位置11时，显示面板300发生堆叠的情况。同时，当显示面板300自折叠位置11切换至展平位置12时，位于避空110中的部分显示面板300可重新移出避空110并舒展，并由支撑板200进行支撑，所述支撑板与显示面板之间不存在间隙，从而保证显示面板300的平整，避免显示面板300受到损伤。
需要说明的是，支撑板200起到固定显示面板300的作用，当显示面板300位于展平位置12时，支撑板200的各个位置均贴合于显示面板300。然而，由于显示面板300需要在折叠位置11和展平位置12之间切换，当显示面板300自展平位置12切换至折叠位置11的过程中，支撑板200的部分与显示面板300分离。由此可知，显示面板300和支撑板200之间并非处处粘合，特别在相邻的两个支撑板200邻接位置的上方的显示面板300并非通过粘接等方式固定连接于支撑板200。进而，使得当显示面板300切换至折叠位置11时，显示面板300的部分可与支撑板200分离，并产生相对弯折，即显示面板300的弯折位置与显示面板300的贴合于支撑板200的位置平滑连接，得到保护。
结合图2和图3所示，在本实施例中，当显示面板300位于展平位置12时，支撑主体210中的两个支撑板200的表面齐平，支撑板200主体所处的平面作为第一平面203。第一平面203和显示面板300形成的基准面平行。当显示面板300位于折叠位置11时，支撑主体210的两个支撑板200所处的平面平行，并作为第二平面204。需要说明的是，第一平面203垂直于第二平面204。通过上述设置，使得当显示面板300位于折叠位置11时，电子设备10可实现对折的折叠方式，便于实现电子设备10的便捷收纳。在使用电子设备10的过程中，若需要对电子设备10进行收纳，可将电子设备10对折以形成如图3所示的形状。此时，显示面板300弯折，并且被机壳100和支撑板200包围，以得到保护，避免在收纳电子设备10的过程中，外界对电子设备10中的显示面板300造成伤害。举例说明，若将现有的电子设备存放于手提袋、口袋中时，显示面板可能会被同样放置于手提袋、口袋中的钥匙、卡片等尖锐的物体划伤。在本实施例中，通过将电子设备10设置为可折叠的形态，使得显示面板300可完全被机壳100包围，避免钥匙、 卡片等尖锐的物体划伤其表面。在本实施例中，当显示面板300位于折叠位置11时，其可处于熄灭状态。
在本实施例中，避空110的个数为一个，从而使得电子设备10可呈现一折的形态变化。当然，在其他实施例中，避空110的个数还可以为两个或者三个以上，从而使得电子设备10可呈现折叠形态变化。当然，每一个避空110的上方需设置至少一个支撑主体210，且相邻的两个支撑主体210会有一个共用的支撑板200。
在本实施例中，支撑板200上设置有固定点220并且，支撑板200可绕固定点220转动，从而实现支撑板200带动显示面板300在展平位置12和折叠位置11之间切换。
如图2和图3所示，必要时结合图1所示，沿第二方向X，每一支撑板200包括第一端201和第二端202，第一端201相对于第二端202远离避空110。需要说明的是，第二方向X垂直于第一方向Y，并且，第一方向Y和第二方向X均垂直于高度方向H。支撑板200包括第一支撑段211和第二支撑段212。第一支撑段211自第一端201延伸至固定点220，第二支撑段212自第二端202延伸至固定点220。当显示面板300位于展平位置12时，第二支撑段212位于避空110的上方。当显示面板300位于折叠位置11时，第二支撑段212位于避空110的内部。
在上述设置中，当显示面板300位于展平位置12时，位于避空110上方的部分显示面板300可以由支撑板200的第二支撑段212进行支撑。当显示面板300自展平位置12切换至折叠位置11的过程中，位于避空110上方的支撑板200的第二支撑段212旋转并进入避空110中，从而使得展平位置时由支撑板200支撑的部分显示面板300也进入避空110。
如图3所示，当显示面板300位于折叠位置11时，位于避空110中的显示面板300呈圆弧状，以避免显示面板300因局部形变过大造成应力集中的现象。而且当显示面板300位于折叠位置11时，支撑主体210的两个支撑板200之间的距离L大于等于显示面板300的最小弯曲直径。每一显示面板300均具有一个固定的最小弯曲直径，最小弯曲直径为以一具体的数值。通过上述设置，当电子设备10可实现对折的折叠方式，即显示面板300位于折叠位置11时，显示面板300可进行正常的弯折，以保证显示面板300不受损伤。
进一步的，第二支撑段212的长度与避空110的深度相同。当显示面板300位于折叠位置11时，第二支撑段212的表面抵靠于避空110的表面，尤其是支撑板200的第 二端202的端面可抵靠于避空110的底面。通过上述设置，便于实现对支撑板200的有效限位，从而保证显示面板300的形状的稳定性。当然，在其他实施例中，避空110的深度还可以大于第二支撑段212的长度。
需要说明的是，这里所指的第二支撑段212的长度具体为，当显示面板300位于展平位置12时，第二支撑段212沿第二方向X的长度(参考图2所示)；或者是，当显示面板300位于折叠位置11时，第二支撑段212沿高度方向H的长度(参考图3所示)。
进一步的，如图2所示，当显示面板300位于展平位置12时，支撑主体210的两个支撑板200的第二端202相接触。通过上述设置，使得当显示面板300位于展平位置12时，相邻的支撑板200的表面齐平，并且，相邻的支撑板200之间不存在间隙。相邻的支撑板200能够更好的配合并起到支撑显示面板300的作用，从而保证当显示面板300位于展平位置12时，显示面板300的下方的任意位置均设置有支撑板200，避免显示面板300出现下陷、易变形等情况，使显示面板300获得较好的支撑效果。
结合图2和图3所示，图2中沿高度方向H，图3中沿第二方向X，支撑板200包括相对设置的第一表面205和第二表面206，第一表面205配置为抵靠显示面板300；至少在第二端处，第一表面205和第二表面206通过圆弧207连接，并且，自第二表面206指向第一表面205的方向，支撑板200的第二端202的尺寸逐渐收窄。
在上述设置中，当显示面板300处于展平位置12时，支撑主体210中的两个支撑板200通过第二端202的靠近第一表面205的一侧抵靠连接，并用于支撑显示面板300。当显示面板300自展平位置12向折叠位置11切换时，支撑主体210中的两个支撑板200以相反的方向转动，并进入避空110。由于自第二表面206指向第一表面205的方向，支撑板200的第二端202的尺寸逐渐收窄，从而使得在支撑板200转动的过程中，相邻的两个支撑板200的第二端202的转动轨迹之间存在间隙，避免两个支撑板200的第二端202在转动过程中相碰撞，以保证转动的稳定性。
如图5-图8所示，进一步的，电子设备10还包括连接机构400。连接机构400设置于避空110正上方且设置于支撑板200和/或机壳100的沿第一方向Y的两端，以避免连接机构400占用避空110的体积，从而使得当显示面板300位于折叠位置11时，进入避空110中的显示面板300不会与连接机构400接触。
如图5和图6所示，在一实施例中，连接机构400可以为沿单一方向延伸的杆状结构。连接机构400的两端分别连接支撑主体210中的两个支撑板200的固定点220。当 显示面板300在展平位置12和折叠位置11之间切换时，连接机构400与机壳100的避空110的相对位置不发生变化。并且，连接机构400和支撑板200之间的摩擦系数较大，从而可通过连接机构400和支撑板200之间的摩擦力维持连接机构400和支撑板200之间的相对位置的稳定，进而保证显示面板300可相对稳固的固定于展平位置12或者折叠位置11。当然，在其他实施例中，支撑板200和显示面板300之间的限位还可以通过增设其他定位装置的方式予以实现。
由于显示面板300需要在展平位置12和折叠位置11之间切换，机壳100也需要设置为柔性机壳100，或者机壳100的设置避空110的部分需要由柔性的、可发生弹性变形的材料制成。
如图7和图8所示，在另一实施例中，连接机构400包括三个定位点410，其中两个定位点410分别连接支撑主体210中两个支撑板200的固定点220，另一个定位点410连接于机壳100。固定点220和定位点410可通过螺栓连接，当然，也可以通过其他方式实现两者的连接。其中，三个定位点410的连线呈三角形(参考图8中虚线所示)。通过上述设置，使得连接机构400和两个支撑板200之间能够形成稳定的三角形结构。
将固定连接机壳100的定位点410作为第一定位点411，将固定连接支撑板200的固定点220的定位点410作为第二定位点412，第一定位点411到两个第二定位点412的距离相同，三个定位点410的连线形成等边或者等腰三角形。当然，在其他实施例中，三个定位点410的连线也可形成三边均不相等的三角形。
需要说明的是，连接机构400和机壳100可以为单独的两个部件，连接机构400和机壳100可通过焊接、榫接、螺纹连接等各种方式实现连接，当然，连接机构400和机壳100也可以为一体成型的部件。
在上述实施例中，连接机构400的表面贴合于避空110的侧面和底面，从而增大连接机构400和避空110的接触面积。同时，连接机构400的形状与避空110的形状相适配，可增强连接机构400定位的稳定性。连接机构400的底端设有第一定位点411，并通过第一定位点411实现连接机构400与机壳100锁死。
进一步的，当连接机构400的数量为n个时，支撑板200的数量为n+1个，避空的个数也为n个。其中，n为正整数。在上述各实施例中，如图1-图8所示，连接机构400的个数为1个，支撑板200的个数为两个。当然，如图9-图13所示，在其他实施例中，连接机构400的个数还可以为多个，支撑板200的数量始终比连接机构400的数量多一 个。那么，除两端的支撑板外的其他支撑板200的两端可分别包括两个固定点且分别连接两个连接机构400，两端的支撑板仅与连接机构连接的一端设置有固定点。在一些实施例中，所有的支撑板两端都有固定点。连接机构400的数量为多个时，当显示面板位于折叠位置时，显示面板位于避空中的部分能够支撑于支撑板200，从而受到保护。同时，显示面板的另一部分能够进入相邻的两个支撑板200的间隙中，避免显示面板出现堆叠的现象，保证用户的体验。显示设备10的各结构及其具体作用方式请适应性参见上文所述，在此不再赘述。
如图11和12所示，当包含四个支撑板时，显示面板可以有两种完全对折方式。需要说明的是，所述显示设备10可以不设置连接机构，当然，也可以设置任一上述的连接机构(未示出)，本申请对此不作限定。此外，显示面板还可以如图13所示方式折叠。
同理，当包含多个支撑板时，显示面板可以有至少两种对折方式。
另外，需要说明的是，附图中仅示出电子设备一个端面的结构，另一端面具有相同的结构。
以上所述仅是本申请的实施例而已，并非对本申请做任何形式上的限制，任何熟悉本专业的技术人员，在不脱离本申请技术方案的范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本申请技术方案的内容，依据本申请的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本申请技术方案的范围内。
