下面通过具体的实施例并结合附图对本申请做进一步的详细描述。
可折叠终端具有折叠后体积小，展开后屏幕尺寸大的优势，是未来终端产品的发展趋势，现在全球各大手机厂商均已在专利上布局，并有相关可折叠终端产品上市。
参见图1和图2所示的终端100，包括支撑组件2、折叠组件1和柔性显示屏20。支撑组件2包括第一支撑板21和第二支撑板22，第一支撑板21和第二支撑板22通过折叠组件1连接，柔性显示屏20连接于第一支撑板21和第二支撑板22，两支撑板和柔性显示屏20能以折叠组件1为中心进行弯折翻转，在终端100折叠合拢时，第 一支撑板21和第二支撑板22之间具有夹角α(α为锐角)，并存在厚度方向的间隙b。其中间隙b的存在具有如下缺陷：
1、间隙b的存在导致两支撑件视觉上呈现明显合不拢状态，影响产品外观体验。
2、间隙b的存在使得大颗粒异物极易进入两支撑件构造的内部腔体，与柔性显示屏20形成夹心结构，当终端100受到挤压和震动时极易造成屏幕划伤和刺破，影响产品质量。
有鉴于此，本申请实施例提供了一种折叠机构及终端，能够解决上述技术问题。
本申请一实施例提供一种终端100，该终端100可以是手机、平板电脑、笔记本等。参见图3所示为本申请实施例终端100的外观结构图，参见图4所示为本申请实施例终端100的爆炸图。终端100包括折叠机构10和柔性显示屏20，折叠机构10包括折叠组件1、支撑组件2和遮蔽组件3，折叠组件1具有第一支撑板21和第二支撑板22，柔性显示屏与折叠组件1和支撑组件2连接，具体连接方式可以是通过胶黏剂c连接。其中，终端100在合拢时，第一支撑板21和第二支撑板22之形成具有间隙，而遮蔽组件3则能遮蔽第一支撑板21和第二支撑板22之间的间隙，既美化了终端100折叠后的外观，又能减少异物进入第一支撑板21和第二支撑板22之间构造的内部腔体，降低异物划伤或刺破柔性显示屏20的概率，从而保护了柔性显示屏20，提高了产品质量，延长了产品使用寿命。
参见图4和图5所示，本申请一实施例提供一种折叠机构10，应用于终端，该折叠机构10包括：折叠组件1、支撑组件2和遮蔽组件3，其中，折叠组件1包括第一折叠板11和第二折叠板12，支撑组件2包括第一支撑板21和第二支撑板22，第一支撑板21连接于第一折叠板11，第二支撑板22连接于第二折叠板12，遮蔽组件3至少沿第一支撑板21和第二支撑板22的长度方向的边延伸设置，第一折叠板11和第二折叠板12驱动连接于遮蔽组件3，第一折叠板11和第二折叠板12合拢时，能驱动遮蔽组件3移动，以遮蔽第一支撑板21和第二支撑板22之间的间隙。
其中，参见图4中的坐标轴，X轴方向为长度方向，Y轴方向为宽度方向，Z轴方向为厚度方向。第一支撑板21和第二支撑板22包括长度方向的边和宽度方向的边，其中长度方向的边应当被理解为第一支撑板21和第二支撑板22两侧平行于X轴方向的两个边，而宽度方向的边应当被理解为第一支撑板21和第二支撑板22两侧平行于Y轴方向的两个边。
本实施方案中，遮蔽组件3可以位于第一支撑板21和第二支撑板22的表面，且至少沿着第一支撑21和第二支撑板22的长度方向的边的边沿延伸。例如：可以在第一支撑板21和第二支撑板22两侧的长度方向的边的边沿设置凹陷槽，在第一折叠板11和第二折叠板12展开时，遮蔽组件3可以至少部分嵌入于凹陷槽内，不影响终端展开状态的外观，而在第一折叠板11和第二折叠板12合拢时，遮蔽组件3能由凹陷槽升起，遮蔽第一支撑板21和第二支撑板22之间的间隙。
本申请实施例中，考虑到第一折叠板11和第二折叠板12合拢时，两者之间会存在间隙，影响外观，且间隙的存在，容易导致大颗粒异物进入第一折叠板11和第二折叠板12之间，而划伤或刺破柔性显示屏20，给用户造成财产损失，因此在折叠机构10上设置了遮蔽组件3，遮蔽组件3可以遮蔽第一支撑板21和第二支撑板22之间 的间隙，既美化了终端100折叠后的外观，又能减少异物进入第一支撑板21和第二支撑板22之间构造的内部腔体，降低异物划伤或刺破柔性显示屏20的概率，从而保护了柔性显示屏20，提高了产品质量，延长了产品使用寿命。
参见图4至图7所示，在一种可能实施的方案中，折叠机构包括驱动组件4，第一折叠板11和第二折叠板12通过驱动组件4驱动连接于遮蔽组件3，第一折叠板11和第二折叠板12合拢时，能带动驱动组件4运动，使得驱动组件4驱动遮蔽组件3升起，以遮蔽第一支撑板21和第二支撑板22之间的间隙，第一折叠板11和第二折叠板12展开时，能带动驱动组件4运动，使得驱动组件4驱动遮蔽组件3降落。
在该实施方案中，驱动组件4将第一折叠板11和第二折叠板12的翻转运动转换为遮蔽组件3的升降运动，使得在第一折叠板11和第二折叠板12合拢时，遮蔽组件3自动升起遮蔽两者之间的间隙，遮蔽组件3在第一折叠板11和第二折叠板12展开时降落复位，不影响终端100在展开时的外观效果。
参见图4至图7所示，在一种可能的实施方案中，遮蔽组件3具有第一轨迹槽33，第一轨迹槽33沿终端100的长度方向延伸设置，其中术语“长度方向”可以参见图4和图5中的X轴方向。驱动组件4可滑动地连接于第一轨迹槽33，第一折叠板11和第二折叠板12合拢时，能使得驱动组件4沿第一轨迹槽33滑动，以带动遮蔽组件3升起，第一折叠板11和第二折叠板12展开时，能使得驱动组件4沿第一轨迹槽33滑动复位，以带动遮蔽组件3降落。
在该实施方案中，遮蔽组件3设置第一轨迹槽33，在第一折叠板11和第二折叠板12展开、合拢的过程中，可带动驱动组件4沿着第一轨迹槽33往复滑动，从而驱动遮蔽组件3升降运动。
参见图5至图7所示，在一种可能的实施方案中，第一轨迹槽33包括沿终端100的长度方向(参见图5的X轴方向)设置的第一端331和第二端332，且沿终端100的厚度方向，第一端331位于第二端332的上方，驱动组件4由第一端331滑入第二端332时，能驱动遮蔽组件升起，驱动组件4由第二端332滑入第一端331时，能驱动遮蔽组件降落。需要说明的是上述术语“厚度方向”参见图4或者图5中的Z轴方向。
在该实施方案中，第一轨迹槽33的第一端331和第二端332位于不同的高度位置，则在驱动组件4滑动的过程中，可驱动遮蔽组件3按照第一轨迹槽33对应的运动轨迹升降运动，当驱动组件4滑动至第一端331时，则遮蔽组件3降落至最低位置，当驱动组件4滑动至第二端332时，则遮蔽组件3升起至最高位置。
具体的，第一轨迹槽33包括连接第一端331和第二端332的弧形过渡段333，其中，弧形过渡段333由第一端331平滑过渡至第二端332，如此使得驱动组件4可沿着第一轨迹槽33平稳的滑动，不会受到大的阻力，减少了驱动组件4在滑动中的负荷，延长了各部件的使用寿命。
参见图8和图9所示，在一种可能的实施方案中，第一支撑板21和第二支撑板连接有连接座23，连接座23具有第二轨迹槽232a，第二轨迹槽232a沿终端100的厚度方向延伸，遮蔽组件3具有连接条34，连接条34可滑动地连接于第二轨迹槽232a，第一折叠板11和第二折叠板12合拢时，连接条34能由第二轨迹槽232a向外滑出， 第一折叠板11和第二折叠板12展开时，连接条34能滑入第二轨迹槽232a。
在该实施方案中，遮蔽组件3中部位置与两折叠板之间通过驱动组件4连接，遮蔽组件3靠近四个角的位置均设置连接条34，通过连接条34与两支撑板连接座23上的第二轨迹槽232a滑动连接，如此在驱动组件4驱动遮蔽组件3中部升降时，则遮蔽组件3四个角处的连接条34可沿着第二轨迹槽232a滑动，使得遮蔽组件3整体升降。
具体的，第二轨迹槽232a为向第一折叠板11或第二折叠板12一侧凸出的弧形槽，连接条34为弧形，曲率与第二轨迹槽232a相匹配。
该实施方案中，第二轨迹槽232a为弧形槽，具有相应的圆心，该圆心可以不在终端100上，在遮蔽组件3升降的过程中，连接条34沿着第二轨迹槽232a滑动，遮蔽组件3整体以圆心为旋转中心转动。
参见图8和图9所示，在一种可能的实施方案中，第一支撑板21和第二支撑板均设有贯通槽24，贯通槽24沿终端100的厚度方向(参见图8的Z轴方向)延伸，连接座23包括连接板231和插接板232，插接板232设有第二轨迹槽232a，连接板231连接于相应的第一支撑板21或第二支撑板22，插接板232插入贯通槽24。
在该实施方案中，在第一支撑板21和第二支撑板22上设置贯通槽24，使得连接座23插接在该贯通槽24内，第二轨迹槽232a位于贯通槽24内，连接条34可以直接插入该第二轨迹槽232a内，在连接座23上开设第二轨迹槽232a，简化了两支撑板的结构，利于批量生产，且连接座23与第一支撑板21、第二支撑板22的装配结构简单，提高了组装效率。
具体的，第一支撑板21和第二支撑板22背离遮蔽组件3的一侧均设置有安装槽25，安装槽25底壁设置贯通槽24，连接板231嵌入安装于安装槽25内，连接板231上设置有连接孔231a，紧固件穿过连接孔231a连接于安装槽25的底壁。
在该实施方案中，连接板231嵌入安装于安装槽25内，连接板231表面和两支撑板表面平滑连接。
参见图10为本申请实施例折叠组件1的结构示意图，图11为图10的局部放大图，图12为折叠组件1展开示意图，图13是折叠组件1合拢的状态图，在一种可能的实施方案中，第一折叠板11和第二折叠板12均设有导向槽13，导向槽13沿终端100的长度方向延伸设置，驱动组件4可滑动地连接于导向槽13，第一折叠板11和第二折叠板12合拢或展开时，导向槽13限定驱动组件4沿导向槽13的延伸方向滑动。
在该实施方案中，导向槽13的设置能限制驱动组件4的滑动轨迹，确保动力稳定的传输。其中，参见图6所示，弧形过渡段333由第一端331向第二端332的方向依次包括第一过渡段333a和第二过渡段333b，其中第一过渡段333a与导向槽13在沿终端100宽度方向上的投影相重合，而第二过渡段333b由第一过渡段333a末端向终端100宽度方向的下方弯曲，第一端331和第二端332具有高度差，使得驱动组件4可以将遮蔽组件3中部位置托起相应的高度。
参见图5至图13所示，在一种可能的实施方案中，驱动组件4包括驱动销钉411，驱动销钉411可滑动地连接于第一轨迹槽33，且驱动销钉411可滑动地连接于导向槽 13。
在第一支撑板21和第二支撑板22合拢的过程中，驱动销钉411在第一过渡段333a滑动时，两折叠板和遮蔽组件3同步转动，当驱动销钉411滑入第二过渡段333b内时，折叠板和遮蔽组件3在终端100厚度方向相互分离，驱动销钉411推动遮蔽组件3升起，实现对第一支撑板21和第二支撑板22之间间隙的遮蔽，而在遮蔽组件3升起的过程中，在第二轨迹槽232a和连接条34的限位作用下，遮蔽组件3整体以上文记载的圆心为旋转中心转动。
参见图12和图14所示，在一种可能的实施方案中，驱动组件4包括驱动件41，折叠机构10还包括支架5，驱动件41一端设有转动连接部412，另一端设有驱动销钉411，转动连接部412可转动连接于支架5。
在该实施方案中，驱动件41一端可转动连接于支架5，另一端通过驱动销钉411可滑动地连接于折叠板，在第一折叠板11和第二折叠板12合拢或展开时，能驱动该驱动销钉411沿导向槽13滑动，使得转动连接部412沿支架5转动，另外折叠机构10还可以包括装饰盖8，装饰盖8覆盖安装于支架5外部。
在一种可能的实施方案中，遮蔽组件3沿第一支撑板21和第二支撑板22的周向设置。
需要说明的是，遮蔽组件3沿第一支撑板21和第二支撑板22的周向设置可以理解为：遮蔽组件沿着第一支撑板21和第二支撑板22一周边沿延伸设置，遮蔽组件3包括沿第一支撑板21和第二支撑板22的长度方向的边的边沿延伸设置的遮蔽段和沿着第一支撑板21和第二支撑板22的宽度方向的边的边沿延伸设置的遮蔽段。
例如：可以在第一支撑板2121和第二支撑板2222的一周边沿设置凹陷槽，遮蔽组件3至少部分嵌入于凹陷槽内，不影响终端展开状态的外观，而在第一折叠板11和第二折叠板12合拢时，遮蔽组件33能由凹陷槽升起，遮蔽第一支撑板2121和第二支撑板2222之间的间隙。
在第一支撑板21和第二支撑板22合拢时，第一支撑板21和第二支撑板22除了连接折叠板的一边，其他三个边均被遮蔽组件3遮蔽，从而实现全方位遮蔽第一支撑板21和第二支撑板22之间的间隙，进一步降低异物进入第一支撑板21和第二支撑板22之间的概率。
参见图3至图5所示，在一种可能的实施方案中，遮蔽组件3包括第一遮蔽件31和第二遮蔽件32，第一遮蔽件31沿第一支撑板21的周向设置；第二遮蔽件32沿第二支撑板22的周向设置，驱动组件4包括两驱动件41，第一折叠板11和第二折叠板12分别通过两驱动件41连接于第一遮蔽件31和第二遮蔽件32。
其中，需要说明的是，上述的第一遮蔽件31沿第一支撑板21的周向设置，可以理解为第一遮蔽件31沿第一支撑板21除连接折叠组件1的一边的其他三个边的边沿延伸设置。而上述的第二遮蔽件32沿第二支撑板22的周向设置，可以理解为第二遮蔽件32沿第二支撑板22除连接折叠组件1的一边的其他三个边的边沿延伸设置。
该实施方案中，第一折叠板11和第二折叠板12合拢时，能分别驱动两驱动件41运动，以带动第一遮蔽件31和第二遮蔽件32升起，遮蔽第一支撑板21和第二支撑板22之间的间隙。若遮蔽组件3为一体件，则至少需要将弯折处设置为柔性结构， 如此则在终端合拢时，会受到遮蔽组件3施加的阻力，不利于终端完全的合拢，针对于此，本申请实施方案中，将遮蔽组件3设置为两个遮蔽件，两个遮蔽件分别连接于折叠机构可相对转动的两部分结构上，不影响折叠机构折叠合拢，且在遮蔽机构合拢时，该两个遮蔽件相贴合，遮蔽第一支撑板21和第二支撑板22之间的间隙。
其中，第一遮蔽件31和第二遮蔽件32可以升起至相贴合，从而遮蔽第一支撑板21和第二支撑板22之间的间隙。
参见图14所示为折叠组件的爆炸图，参见图15所示为图14中局部放大图，参见图16所示为折叠组件与支架的配合结构图，参见图17所示为支架部分的装配结构图。在一种可能的实施方案中，支架5安装有同步传动组件6，两驱动件41通过同步传动组件6传动连接，同步传动组件6限定两驱动件41同步转动，以使得第一遮蔽件和第二遮蔽件同步升降。
在该实施方案中，通过设置同步传动组件6，使得第一折叠板11和第二折叠板12在合拢或展开时，两驱动件41随两折叠板同步转动，从而驱动第一遮蔽件31和第二遮蔽件32同步升降，完成遮蔽动作。
具体的，支架5可以具有装配槽51，同步传动组件6包括设置于装配槽51内的同步齿轮组，驱动件41的转动连接部412设有啮合齿，两驱动件41的转动连接部412均设于装配槽51内，并分别与同步齿轮组两端的两个齿轮相啮合，其中，同步齿轮组具有偶数个齿轮。转动连接部412和同步齿轮组的各齿轮均设置有贯通槽，折叠机构10还包括多个销钉9，各销钉9贯穿各贯通槽，并连接于装配槽51上。
在该实施方案中，驱动件41的转动连接部412与同步齿轮组端部的齿轮啮合，使得两驱动件41同步反向运动，驱动第一遮蔽件和第二遮蔽件同步升降。
参见图14至图17所示，在一种可能的实施方案中，支架5具有旋转槽52，第一折叠板11和第二折叠板12均设有连接凹槽14，折叠机构10包括转动连接件7，转动连接件7具有转动体71，转动体71可转动连接于旋转槽52，转动连接件7远离转动体71的一端嵌入安装于连接凹槽14。
具体的，旋转槽52内设有弧形轨迹条521，转动体71设有弧形轨迹槽71a，弧形轨迹槽71a可滑动地连接于弧形轨迹条521。
该实施方案中，在合拢该折叠机构10时，对支撑板施加弯折力，支撑板、折叠板与转动连接件7一起沿弧形轨迹条521与弧形轨迹槽71a配合形成的运动轨迹旋转。折叠板同时能带动驱动销钉411运动，驱动销钉411带动转动连接部412和同步齿轮组同步旋转。折叠板和支撑板在运动过程中具有确定的轨迹，在合拢至终点位置时，两折叠板具有夹角α，夹角α为锐角。夹角α的存在使得终端100在折叠后，具有棒球形的间隙，本申请的遮蔽组件3在升起后，能够遮蔽该间隙，既美化了终端100折叠后的外观，又保护了柔性显示屏20，显著的提高了产品质量。
