具体实施方式
为了更好地理解本申请，下面结合图1至图9对本申请实施例的可折叠结构件及显示装置进行详细描述。
请一并参阅图1至图3，根据本申请实施例提供的显示装置，显示装置包括显示面板1和用于支撑显示面板1的可折叠结构件2。显示装置能够在展平状态和弯折状态之间转变。弯折状态包括内折状态和外折状态。
显示面板1可在显示装置厚度方向(图1中的Z方向)上设置于可折叠结构件2的一侧，在内折状态，显示面板1位于内折状态下显示装置的内表面并被可折叠结构件2包裹，以使可折叠结构件2向显示面板1提供更好的保护作用。在外折状态，显示面板1位于外折状态下显示装置的外表面，可折叠结构件2被折叠在显示面板1内，显示面板1能够更好的显示。
在另一些实施例中，显示面板1亦可设置于显示装置在厚度方向上的两侧，在内折状态和外折状态，均有显示面板1进行显示。显示面板1例如呈环状，可折叠结构件2位于环状显示面板1内。
请参阅图4，可折叠结构件2可以为上述第一方面实施例提供的显示装置中的可折叠结构件2。
当显示装置处于展平状态时，可折叠结构件2处于展平状态，可折叠结构件2的展平状态参照图1所示。当显示装置处于内折状态时，可折叠结构件2处于内折状态，可折叠结构件2的内折状态参照图2所示。当显示装置处于外折状态时，可折叠结构件2处于外折状态，可折叠结构件2的外折状态参照图3所示。
在本申请实施例的可折叠结构件2中，可折叠结构件2包括结构主体100和卡扣组件200。结构主体100包括沿第一方向(图4中的X方向) 设置的第一主体部110、第二主体部120和弯折部130，结构主体100可以通过弯折部130在展平状态、内折状态和外折状态之间转变。当支撑结构件用于支撑显示面板1时，支撑结构件能够带动显示面板1在不同状态之间转变，实现显示面板1的多状态显示。卡扣组件200包括相互卡扣配合的第一卡扣件210和第二卡扣件220，第一卡扣件210和第二卡扣件220中的一者设置第一主体部110，另一者设置于第二主体部120，使得当结构主体100位于内折状态和外折状态时，第一主体部110和第二主体部120均能够通过第一卡扣件210和第二卡扣件220相互卡扣配合。因此在本申请实施例中，通过设置第一卡扣件210和第二卡扣件220，能够解决显示装置折叠后不能保持而自动打开的问题。
第一卡扣件210和第二卡扣件220在结构主体100上的设置位置有多种。参照图4，结构主体100包括在可折叠结构件2厚度方向(图4中的Z方向)上相对设置的第一表面140和第二表面150及连接第一表面140和第二表面150的侧表面160。第一卡扣件210和第二卡扣件220设置于侧表面160，从而避免第一卡扣件210和第二卡扣件220与显示面板1发生干涉。
侧表面160包括在可折叠结构件2宽度方向(图4中的Y方向)上相对设置的第一侧面161和第二侧面162，第一卡扣件210和第二卡扣件220设置于第一侧面161和/或第二侧面162，弯折部130的弯折折线沿宽度方向延伸。第一侧面161和第二侧面162通常是用户在使用显示装置时不会持握的一面，第一卡扣件210和第二卡扣件220设置于第一侧面161和/或第二侧面162。当可折叠结构件2用于显示装置时，第一卡扣件210和第二卡扣件220不影响用户持握显示装置，还能够避免用户持握影响第一卡扣件210和第二卡扣件220相互卡扣配合。
第一卡扣件210设置于第一主体部110远离第二主体部120的一侧，第二卡扣件220设置于第二主体部120远离第一主体部110的一侧。即第一卡扣件210和第二卡扣件220的设置位置距离弯折部130较远，使得第一卡扣件210和第二卡扣件220之间使用较小的卡扣力即可实现卡扣配合。
第一卡扣件210和第二卡扣件220相互卡扣配合的方式有多种。第二卡扣件220相对第二主体部120在第一位置和第二位置之间可转动设置，以使在内折状态下，第一主体部110和第二主体部120能够通过第一卡扣件210和位于第一位置的第二卡扣件220相互卡扣连接，在外折状态下，第一主体部110和第二主体部120能够通过第一卡扣件210和位于第二位置的第二卡扣件220能够相互卡扣连接。
在这些可选的实施例中，第二卡扣件220的位置可转动设置，在内折和外折状态，可以通过一个第二卡扣件220与第一卡扣件210配合实现第一主体部110和第二主体部120的卡扣连接，以简化卡扣组件200的结构。
第一位置是指第二卡扣件220在该位置时，内折状态下的可折叠结构件2的第一主体部110和第二主体部120能够相互卡扣连接。如图2所示，图2中的第二卡扣件220位于第一位置。
第二位置是指第二卡扣件220在该位置时，外折状态下的可折叠结构件2的第一主体部110和第二主体部120能够相互卡扣连接。如图3所示，图3中的第二卡扣件220位于第二位置。
第二卡扣件220相对第二主体部120在第一位置和第二位置之间可转动设置的方式有多种，例如第二卡扣件220绕沿第一方向延伸的第二轴线可翻转设置。当结构主体100由内折状态转变至外折状态时，第一卡扣件210由第二卡扣件220在结构主体100厚度方向上的一侧移动至第二卡扣件220的另一侧。如图2和图3所示，当结构主体100由内折状态转变至外折状态时，第一卡扣件210由第二卡扣件220的上方移动至下方。第二卡扣件220可翻转设置，当结构主体100由内折状态转变至外折状态时，通过翻转第二卡扣件220使得第二卡扣件220能继续与第一卡扣件210卡扣配合。
第一卡扣件210和第二卡扣件220的设置方式有多种。参阅图5和图6，第一卡扣件210包括卡扣柱211，第二卡扣件220包括与卡扣柱211卡扣配合的卡扣环221，卡扣环221相对第二主体部120绕第二轴线可翻转设置。通过翻转卡扣环221，使得在内折状态和外折状态下，第一主体部 110和第二主体部120均能够通过卡扣柱211和卡扣环221相互卡扣配合。
参阅图5，卡扣柱211背离第一主体部110的一端设置有与卡扣环221卡扣配合的固定部212，以使卡扣环221能够止挡于固定部212朝向第一主体部110的一侧。当卡扣柱211和卡扣环221相互配合时，至少部分卡扣环221能够位于固定部212和第一主体部110之间，固定部212向卡扣环221提供限位力，保证卡扣环221和卡扣柱211相对位置的稳定性。
固定部212的个数和形状设置方式有多种。参阅图5，固定部212设置为位于卡扣柱211的圆柱面上的凹陷结构，卡扣环221卡扣在凹陷结构上，在内折状态或外折状态下，卡扣环221和卡扣柱211相互配合时，固定部212能够向卡扣环221提供限位力。或者固定部212设置为两个凸起结构且分别设于卡扣环221在厚度方向上的两侧，在内折状态和外折状态下，卡扣环221和卡扣柱211相互配合时，固定部212能够向卡扣环221提供限位力。
在另一些可选的实施例中，固定部212呈环状，环绕于卡扣柱211的周侧设置。当卡扣柱211和卡扣环221相互卡扣配合时，固定部212能够向卡扣环221提供不同方向上的限位力。
卡扣柱211设置于第一主体部110的方式有多种，例如卡扣柱211固定于第一主体部110的侧面。在另一些可选的实施例，卡扣柱211沿自身延伸方向可伸缩地设置于第一主体部110。可选的，卡扣柱211在位于第一主体部110内的位置和伸出第一主体部110外的位置之间可移动设置。当可折叠结构件2位于展开状态，无需卡扣柱211和卡扣环221配合时，卡扣柱211位于第一主体部110内，保证可折叠结构件2外观的完整和美观性。当可折叠结构件2位于内折状态或外折状态，需要卡扣柱211和卡扣环221相互配合时，卡扣柱211伸出于第一主体部110外，使得第一主体部110和第二主体部120能够通过卡扣柱211和卡扣环221相互卡扣配合。
在另一些可选的实施例中，第二卡扣件220相对第二主体部120绕沿第二方向延伸的第一轴线可转动设置，使得第二卡扣件220相对第二主体 部120能够在第一位置和第二位置之间转动。
当第二卡扣件220设置于第一侧面161和/或第二侧面162时，第二方向为宽度方向，第一轴线沿宽度方向延伸。当第二卡扣件220设置于沿第一方向相对的端面上时，第二方向和第一方向平行，第一轴线沿第一方向延伸。只要第二卡扣件220绕第一轴线转动能够在第一位置和第二位置之间转动，使得内折状态和外折状态下的第一主体部110和第二主体部120均能够通过第二卡扣件220和第一卡扣件210相互卡扣连接即可。
当第二卡扣件220相对第二主体部120绕第一轴线可转动设置时，可选的，第二卡扣件220相对第二主体部120可转动至第一位置和第二位置之间的预设位置，以使当第一主体部110和第二主体部120之间呈预设角度，可折叠结构件2呈V形的状态下，第一主体部110和第二主体部120能够通过第一卡扣件210和位于预设位置的第二卡扣件220相互卡扣设置。预设位置可以为第一位置至第二位置路径上的任一位置。通过设置第二卡扣件220位于预设位置，第一主体部110和第二主体部120之间呈现预设角度，满足用户的多样化需求。
第二卡扣件220相对第二主体部120可转动的设置方式有多种。参照图6，第二卡扣环221还包括连接销222，连接销222可转动地连接于第二主体部120，卡扣环221通过连接销222连接于第二主体部120，卡扣环221相对于连接销222绕轴线可翻转设置。卡扣环221通过连接销222相对第二主体部120可转动设置，便于将卡扣环221通过翻转和转动的方式设置于指定位置。
请一并参阅图6和图7，第二主体部120上开设有安装孔121。连接销222包括在其延伸方向上分布的连接端222a和安装端222b，卡扣环221连接于连接端222a，安装端222b可转动地连接于安装孔121，连接销222可转动地设置于第二主体部120上的安装孔121内。
可安装端222b的径向尺寸小于连接端222a的径向尺寸。安装端222b的径向尺寸较小，能够减小连接销222在第二主体部120上占据的空间。
请一并参阅图7和图8，连接端222a包括开口相对设置的两个连接孔222c，卡扣环221具有相对设置的两个自由端221a，各自由端221a分别 可转动地设置于各连接孔222c内。卡扣环221由条状结构件弯折形成，条状结构件的两端对接形成卡扣环221，因此在卡扣环221上形成相对设置的两个自由端221a。各自由端221a能够分别设置于各连接孔222c内，从而将卡扣环221连接于连接端222a上。
自由端221a的截面呈圆形，连接孔222c具有圆柱形的内壁面，使得自由端221a在连接孔222c内可转动设置，令卡扣环221能够通过两个自由端221a和连接孔222c的配合相对连接端222a可翻转设置。
参照图6，第二主体部120还包括与安装孔121连通的让位空间122，安装端222b由安装孔121伸入让位空间122，第二卡扣件220还包括止挡部223，止挡部223位于让位空间122并连接于安装端222b，以防连接销222由安装孔121脱落。
在这些可选的实施例中，通过。
请一并参阅图7至图9，安装端222b上设置有令连接销222稳定固定于第二主体部120上的止挡部223。止挡部223包括呈环状的本体部223a和位于本体部223a上的缺口223b，止挡部223通过缺口223b将本体部223a套设于安装端222b。止挡部223通过设置缺口223b来安装于安装端222b，能够提高可折叠结构件2的安装效率。
安装端222b上设置有安装槽222d，以使止挡部223能够卡扣于安装槽222d内。
参阅图6，第二主体部120上设置有收纳卡扣环221的让位槽123。让位槽123内设置有挤压部124，以使卡扣环221位于让位槽123内时，挤压部124和卡扣环221过盈配合，从而保证卡扣环221和让位槽123相对位置的稳定性。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
