在本实施方式中，以所述电子设备1为内折式电子设备为例进行示意。即，当所述电子设备1处于折叠状态时，所述柔性件30位于所述折叠装置100的内侧。内折式电子设备1可有效降低所述柔性件30受到撞击的可能性，有利于延长所述柔性件30的使用寿命。需要说明的是，本申请提供的主要发明构思也可适用于外折式电子设备。
当所述电子设备1处于展开状态时，所述柔性件30在所述折叠装置100的作用下展开，所述柔性件30能够显露出来，有利于实现大屏幕显示或大屏幕操作。当所述电子设备1处于折叠状态时，便于携带。可以理解地，上面对电子设备1的介绍仅是所述折叠装置100及所述折叠壳体10的一种应用方式的介绍，不应当理解为对本申请提供的折叠装置100和折叠壳体10的限定。下面结合附图对折叠装置100进行介绍。
可以理解地，上面对电子设备1的介绍仅是所述折叠装置100及所述折叠壳体10的一种应用方式的介绍，不应当理解为对本申请提供的折叠装置100和折叠壳体10的限定。下面结合附图对折叠装置100进行介绍。
请一并参阅图4、图5及图6，图4为本申请一实施方式提供的折叠装置一视角下的立体示意图；图5为图4中折叠装置另一视角的立体示意图；图6为图4中折叠装置的分解示意图。所述折叠装置100包括支撑组件1100以及转动组件1200。所述支撑组件1100包括两个支撑件111。所述转动组件1200包括主体120以及设置于所述主体120相对两侧的转动机构130。换而言之，所述转动组件1200包括两个转动机构130，一转动机构130设置于所述主体120一侧，另一转动机构130设置于所主体120的另一侧。在本实施方式中，两个转动机构130的结构相同，下面对一个转动机构130的结构进行描述。所述转动机构130包括第一转动件131、第二转动件132及第三转动件133以及连接件134。所述第一 转动件131的一端转动连接于所述主体120，所述第一转动件131的另一端转动连接于所述支撑件111。所述第二转动件132的一端转动连接于所述主体120，所述第二转动件132的另一端转动连接于所述连接件134。所述第三转动件133的一端转动连接于所述主体120，所述第三转动件133的另一端滑动连接于所述连接件134。所述连接件134与所述支撑件111转动连接，所述连接件134相对所述主体120转动以带动所述第一转动件131、所述第二转动件132及所述第三转动件133转动，进而带动两个所述支撑件111相互弯折或相互展开。
所述支撑件111，也称为斜板，所述支撑件111对应所述柔性件30的可弯折部310设置。在一实施方式中，所述支撑件111通过粘结胶、或双面胶等固定于可弯折部310的相背的两端。在另一实施方式中，所述支撑件111与所述可弯折部310之间并不固定。当两个支撑件111相互弯折时，两个支撑件111用于对所述可弯折部310的位置进行限位，防止所述可弯折部310窜动。
所述支撑件111在所述折叠装置100处于展开状态时展开，在应用于电子设备1时可较好地支撑展开状态的柔性件30。当所述支撑件111在所述折叠装置100处于折叠状态时折叠，且所述支撑件111靠近所述主体120的一端相较于背离所述主体120的另一端倾斜，使得所述折叠装置100处于折叠状态时，两个支撑件111靠近所述主体120的一端之间的距离d1大于两个支撑件111背离所述主体120的另一端之间的距离d2(请参阅图2)。因此，当所述折叠装置100处于折叠状态时，所述折叠装置100的横截面呈现水滴形的收容空间。当所述折叠装置100应用于折叠壳体10及电子设备1时，有利于减小所述折叠壳体10及电子设备1的折合缝隙，提高外观表现力，且增加了对所述电子设备1中的柔性件30的弯折控制，有利于减小所述柔性件30的折痕。
所述主体120也称为承载座，或支架。所述转动组件1200包括主体120以及设置于所述主体120相对两侧的转动机构130。两个所述支撑件111设于所述主体120的相对的两侧，两个所述支撑件111中的一者通过一转动机构130连接所述主体120，两个所述支撑件111中的另一者通过另一转动机构130连接所述主体120。两个转动机构130可沿主体120的中线对称设置，或非对称设置。在本实施方式及本实施方式的示意图中，两个转动机构130沿主体120的中线对称设置。当两个支撑件111呈展开状态时，两个支撑件111分别设置于所述主体120的两侧。
在一实施方式中，所述连接件134可固定至所述壳体500，从而实现当所述壳体500转动时带动所述连接件134转动。所述连接件134与壳体500可以为一体式结构或分体式结构。当连接件134与壳体500为一体式结构时，连接件134与壳体500可通过一道工序制备而成，只不过为了便于理解，人为将连接件134与壳体500进行了不同的命名。当连接件134与壳体500为分体式结构时，连接件134与壳体500为两个独立的部件，通过各种方法例如粘接、螺钉连接、卡扣连接等方法将连接件134固设于壳体500上。本实施方式仅以连接件134与壳体500为分体式结构进行示意性说明。
所述第一转动件131的一端转动连接于所述主体120，所述第一转动件131的另一端转动连接于所述支撑件111。所述第二转动件132的一端转动连接于所述主体120，所述第二转动件132的另一端转动连接于所述连接件134。所述第三转动件133的一端转动连接于所述主体120，所述第三转动件133的另一端滑动连接于所述连接件134。所述连接件134与所述支撑件111转动连接，所述连接件134相对所述主体120转动以带动所述第一转动件131、所述第二转动件132及所述第三转动件133转动，进而带动两个所述支撑件111相互弯折或相互展开。
因此，当所述折叠装置100处于展开状态时，所述支撑件111能够为柔性件30提供更好地支撑；在所述折叠装置100处于折叠状态时，所述折叠装置100的横截面呈现水滴形的收容空间，当所述折叠装置应用于折叠壳体10及电子设备1时，有利于减小所述折叠壳体10及电子设备1的折合缝隙，提高外观表现力，且增加了对电子设备1中的柔性件30的弯折控制，有利于减小所述柔性件30的折痕。
需要说明的是，所谓转动，是指两个运动件可绕转动轴线进行圆周运动。两个运动件转动时，可绕转动轴线运动圆周的部分或全部。比如，第一转动件131的一端转动连接于所述主体120，则，所述第一转动件131与所述主体120可绕转动轴线进行圆周运动。所谓滑动，是指两个运动件平行运动，两个运动件之间只有位移变化，没有角度变化。比如，在本实施方式中，所述第三转动件133的另一端滑动连接于所述连接件134，则表示所述第四转的件133的所述另一端与所述连接件134之间有位移变化， 而没有角度的变化。接下来各个部件之间的转动或滑动时可参阅本处说明，接下来不再赘述。所谓滚动，是指两个运动件之间既有位移变化又有角度变化。
由上述描述可知，所述支撑件111可相互弯折或相互展开，因此，所述折叠装置100具有折叠状态及展开状态，且可由展开状态切换至折叠状态，以及由折叠状态切换至展开状态。可以理解地，所述折叠装置100还具有处于折叠状态及展开状态之间的悬停状态(也称为中间态)。当所述折叠装置100处于折叠状态时，两个所述支撑件111均位于所述主体120的同一侧，且所述支撑件111不能够再继续折叠。当所述折叠装置100处于展开状态时，两个所述支撑件111均位于所述主体120相背的两侧，且两个支撑件111处于平整或近似平整的状态。当两个支撑件111处于平整状态时，两个支撑件111邻近柔性件30设置的表面共面。当两个支撑件111处于近似平整的状态时，两个支撑件111邻近柔性件30设置的表面近似共面。所述折叠装置100的状态和所述电子设备1的状态相关。当所述折叠装置100中的两个支撑件111相互弯折时，会带动所述柔性件30相对弯折；当所述折叠装置100中的两个支撑件111相互展开时，会带动所述柔性件30相互展开。因此，当所述折叠装置100处于折叠状态时，所述电子设备1也处于折叠状态；当所述折叠装置100处于展开状态时，所述电子设备1也处于展开状态。
在本实施方式中，所述第一转动件131的一端连接所述主体120，所述第一转动件131的另一端转动连接于所述支撑件111，其中，所述第一转动件131的所述一端与所述连接件134的所述另一端相背设置。所述第二转动件132的一端转动连接于所述主体120，所述第二转动件132的另一端转动连接于所述连接件134，其中，所述第二转动件132的所述一端与所述第二转动件132的所述另一端相背设置。所述第三转动件133的一端转动连接于所述主体120，所述第三转动件133的另一端滑动连接于所述连接件134，其中，所述第三转动件133的所述一端与所述第三转动件133的所述另一端相背设置。
所述连接件134相对所述主体120转动以带动所述第一转动件131、所述第二转动件132及所述第三转动件133转动，进而带动两个所述支撑件111相互弯折或相互展开，详细描述如下。具体地，当两个转动机构130中的每个连接件134相互靠拢时，两个第二转动件132相对于所述主体120及所述连接件134转动而相互靠拢，两个第三转动件133相对于所述主体120转动且相对于所述连接件134滑动，所述支撑件111相对所述连接件134转动，两个所述第一转动件131相对于所述主体120及所述支撑件111转动，以使两个支撑件111相互折叠。当两个转动机构130中的每个连接件134相互远离时，两个第二转动件132相对于所述主体120及所述连接件134转动而相互远离，两个第三转动件133相对于所述主体120转动且相对于所述连接件134滑动，所述支撑件111相对所述连接件134转动，两个第一转动件131相对于所述主体120及所述支撑件111转动，以使两个支撑件111相互展开。综上所述，本申请实施方式提供的折叠装置100中，所述支撑件111与所述主体120之间、所述第一转动件131与所述支撑件111之间、所述第二转动件132与所述主体120之间、所述第二转动件132与所述连接件134之间、所述第三转动件133与所述主体120之间均为转动连接关系，所述第三转动件133与所述连接件134之间为滑动连接关系。当所述折叠装置100处于展开状态时，能够为所述折叠装置100所承载的柔性件30提供较好的支撑。此外，当所述折叠装置100所应用的电子设备1跌落时，支撑件111相对不容易晃动，具有较好的可靠性。
此外，相关技术中，滚动连接通常是由销钉和滑槽配合实现，异形槽的加工精度不高，支撑件111的运动精度控制较为困难。而本申请实施方式中的折叠装置100中由于存在转动连接和滑动连接，相较于滚动连接而言，加工精度较高，可使得支撑件111的运动精度控制较为容易。
请一并参阅图7至图11，图7为图4中所示的折叠装置沿I-I线的剖面示意图；图8为图7中所示的折叠装置另一视角的示意图；图9为图4中提供的折叠装置中第一转动件与主体及支撑件配合关系示意图；图10为图9所示的结构的立体分解图；图11为图9中沿II-II线的剖面图。请一并参阅图12至图15，图12为7中所示的折叠装置处于折叠状态的剖面示意图；图13为图12中提供的处于折叠状态的折叠装置中第一转动件与主体及支撑件配合关系示意图；图14为图13中所示的结构的立体分解图；图15为图13中沿III-III线的剖面图。因本申请实施方式中，一个第一转动件131与主体120及支撑件111之间的配合关系和另一第一转动件131与主体120及支撑件件111之间的配合关系相同，因此，在部分附图中仅示意出一个第一转动件131及一个支撑件111。所述第一转动件131与所述主体120之间 通过第一圆弧槽1311及第一圆弧轨121配合连接。所述第一圆弧槽1311设置于所述第一转动件131和所述主体120中的一者，所述第一圆弧轨121设置于所述第一转动件131和所述主体120中的另一者。
在本实施方式的示意图中，以所述第一转动件131上具有第一圆弧槽1311，且以所述主体120具有第一圆弧轨121为例进行示意。可以理解地，不应当理解为对本申请第一转动件131与所述主体120之间的转动连接的限定。在其他实施方式中，第一转动件131上还可设置第一圆弧轨121，相应地，所述主体120具有第一圆弧槽1311。在其他实施方式中，所述第一转动件131上具有第一圆弧轨121及第一圆弧槽1311；相应地，所述主体120上具有第一圆弧槽1311及第一圆弧轨121；所述主体120的第一圆弧槽1311与所述第一转动件131上的第一圆弧轨121配合，相应地，所述第一主体120的第一圆弧轨121和第一转动件131上的第一圆弧槽1311配合。具体地，以所述第一转动件131上具有第一圆弧槽1311，且以所述主体120具有第一圆弧轨121为例进进行说明。所述主体120具有第一收容空间120a，所述第一圆弧轨121设置于所述主体120形成所述第一收容空间120a的侧壁上。
为了理解第一收容空间120a的位置，下面先对所述主体120的结构进行描述。所述主体120具有在两个支撑件111呈折叠状态时邻近所述支撑件111的端面。具体地，请参阅图10，将所述两个支撑件111呈折叠状态时邻近所述支撑件111的端面命名为第一端面123，将与所述第一端面123相背的表面命名为第二端面124。此外，所述主体120还具有两个连接面125，两个所述连接面125分别连接所述第一端面123及所述第二端面124。换而言之，所述主体120具有第一端面123、第二端面124、及两个连接面125。所述第一端面123及所述第二端面124相背设置，所述连接面125连接所述第一端面123及所述第二端面124，且两个连接面125相背设置。当两个支撑件111呈折叠状态时，两个支撑件111中的一者位于一个连接面125的一侧，两个支撑件111的另一者位于另一连接面125的一侧；当两个支撑件111呈折叠状态时，两个支撑件111位于第一端面123的一侧，且第一端面123相较于第二端面124邻近两个支撑件111。
在本实施方式中，所述第一端面123的宽度大于所述第二端面124的宽度。由于所述第一端面123需要开设开口安装第一转动件131、第二转动件132及第三转动件133，以及柔性件30等部件，因此，第一端面123的宽度较大，可便于上述部件的安装。第二端面124的尺寸较小，可减小所述主体120的尺寸。另外，所述连接面125为弧形或近似为弧形，可在所述折叠装置100折叠时，可避让所述第一转动件131、第二转动件132及第三转动件133以及壳体500等结构件，防止所述折叠装置100在折叠的过程中上述结构件与连接面125干涉。
所述第一收容空间120a的开口位于所述第一端面123，且贯穿其中一个连接面125。由于所述支撑件111的数目为两个，因此，所述主体120部具有间隔设置的两个第一收容空间120a。在本实施方式的示意图中，以两个第一收容空间120a沿着所述主体120的宽带方向排布为例进行示意。
所述第一收容空间120a的开口位于第一端面123，且贯穿其中的一个连接面125，从而可便于所述第一转动件131装设于所述第一收容空间120a内，便于所述第一转动件131与所述主体120之间配合连接。
所述主体120具有形成所述第一收容空间120a相对的两个侧壁。所述第一圆弧槽1311或第一圆弧轨121设置于两个侧壁中的至少一者。
本实施方式中，所述第一转动件131与所述主体120之间通过第一圆弧槽1311及第一圆弧轨121配合连接，一方面可使得所述第一转动件131可与主体120转动连接，另一方面可方便在第一转动件131及所述主体120上加工形成所述第一圆弧槽1311及第一圆弧轨121，此外，还可便于所述第一转动件131与所述主体120之间装配，且使得装配后的折叠装置100较为紧凑。
此外，所述第一圆弧槽1311和第二圆弧轨122相对转动时的转动轴为虚拟轴，换而言之，所述第一圆弧槽1311和所述第二圆弧轨122相对转动时绕着所述虚拟轴转动。采用虚拟轴的方式相较于实体转轴而言，虚拟转轴的位置可以根据需要设计，第一转动件131与所述主体120的转动轴线更接近理论设计的位置，从而使得所述第一转动件131相较于所述主体120转动时具有较高精度的运动轨迹。此外，在所述折叠装置100在运动的过程中或者在折叠装置100处于展开状态或折叠状态时，不会和所述折叠装置100所承载的柔性件30产生干涉，且还在所述第一转动件131与所主体120的转动轴线更靠近所 述柔性件30时，避免所述第一转动件131损伤或刺穿所述柔性件30。
在本实施方式中，所述主体120具有第一收容空间120a。所述主体120形成所述第一收容空间120a相对的两个侧壁上均设置有所述第一圆弧槽1311及第一圆弧轨121中的一者，所述第一转动件131相背的两侧均设置有所述第一圆弧槽1311及第一圆弧轨121中的另一者。
请继续参阅图10，在实施方式的示意图中，两个所述侧壁沿着所述主体120的长度方向排布。所述主体120形成所述第一收容空间120a相对的两个侧壁上均设置有所述第一圆弧槽1311及第一圆弧轨121中的一者，所述第一转动件131相背的两侧均设置有所述第一圆弧槽1311及第一圆弧轨121中的另一者。因此，当所述第一转动件131与所述主体120配合时通过两个第一圆弧槽1311和两个第一圆弧轨121配合，从而可提升所述第一转动件131相对于所述主体120转动时的稳定性。
在本实施方式的示意图中，以所述主体120形成所述第一收容空间120a的相对的两个侧壁上均设置第一圆弧轨121为例，且所述第一转动件131相背的两侧均设置有第一圆弧槽1311为例进行示意，不应当理解为对本申请实施方式提供的折叠装置100的限定。在其他实施方式中，所述主体120形成所述第一收容空间120a相对的两个侧壁上均设置有第一圆弧槽1311，所述第一转动件131相背的两侧均设置有第二圆弧轨122。在另外的实施方式中，所述主体120形成所述第一收容空间120a的相对的两个侧壁中的一者设置第一圆弧轨121，两个侧壁中的另一种设置第一圆弧槽1311；相应地，所述第一转动件131相背的两侧分别设置有第一圆弧槽1311及第一圆弧轨121，所述第一转动件131的第一圆弧槽1311与所述主体120的第一圆弧轨121配合，所述第一转动件131的第一圆弧轨121和所述主体120的第一圆弧槽1311配合。

具体地，请参阅图14，所述支撑件111具有支撑本体部1113及凸出部1114。所述凸出部1114设置于所述支撑本体部1113朝向所述连接件134的一侧，所述凸出部1114具有第一连接孔1312，所述第一转动件131的所述另一端对应所述凸出部1114设置，且所述第一转动件131的所述另一端具有第一连接孔1312，第一连接轴1111穿设于两个第一连接孔1312中。
本实施方式中，所述第一转动件131与所述支撑件111之间通过第一连接轴1111与第一连接孔1312配合连接，即通过实体的连接轴可使得所述第一转动件131与所述支撑件111可转动连接。实体的连接轴可使得所述第一转动件131与所述支撑件111之间转动连接时需要的空间较小，有益于实现第一转动件131与所述支撑件111配合部件的小型化。此外，所述第一连接轴1111与所述第一连接孔1312之间的配合间隙比较容易控制，不容易产生晃动。

折叠装置100所述装饰件140包括本体部141及侧壁142。所述侧壁142与所述本体部141弯折相连，以形成容置空间140a。所述容置空间140a用于收容所述主体120的至少部分，当两个支撑件111呈展开状态时，两个所述支撑件111分别位于所述侧壁142的外侧。
当两个支撑件111呈展开状态时，两个所述支撑件111分别位于所述侧壁142的外侧，即，所述侧壁142位于所述支撑件111与所述主体120之间，从而使得所述装饰件140能够遮挡支撑件111及所述连接件134形成的组件与所述主体120之间的间隙，进而能够减少或者防止灰尘、水汽等进入到所述主体120及与主体120连接的第一转动件131、第二转动件132及第三转动件133内。
此外，所述装饰件140还能够对所述主体120进行保护。在其他实施方式中，所述装饰件140上还可设置有装饰图案等，以使得所述装饰件140具有更加醒目的装饰效果。
