附图标记说明：
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属 于本申请保护的范围。此外，应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。在本申请中，在未作相反说明的情况下，使用的方位词如“上”和“下”通常是指装置实际使用或工作状态下的上和下，具体为附图中的图面方向；而“内”和“外”则是针对装置的轮廓而言的。
本申请实施例提供一种显示装置，以下进行详细说明。需要说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
如图1、图2和图8所示，显示装置10包括中框组件100，中框组件100包括至少两个转动连接的中框本体110，通过中框本体110的转动能够保证显示装置10在使用过程中进行折叠。转动连接的两个中框本体110之间具有第一间隙120，能够避免显示装置10在进行折叠时两个中框本体110之间出现干扰。其中，中框本体110具有支撑面111，用于支撑显示装置10中的其他结构，保证显示装置10的结构稳定性。
显示装置10包括滑动组件200，滑动组件200设置在中框本体110的支撑面111上，滑动组件200包括至少两个滑动件210，滑动件210与中框本体110对应滑动连接。通过将滑动组件200分为与中框本体110对应连接的滑动件210，能够避免滑动组件200对中框本体110的转动造成干扰，保证显示装置10的正常使用。
其中，滑动件210的滑动方向与第一间隙120的延伸方向呈夹角。当显示装置10发生跌落时，由于转动连接的两个中框本体110之间存在第一间隙120，且两个中框本体110通过转轴等结构连接，而转轴等结构的自身强度较低，容易发生变形，从而导致两个中框本体110会发生相对移动，直至两个中框本体110相互抵接，即中框本体110的运动方向与第一间隙120的延伸反向呈夹角。
通过将滑动件210的滑动方向与第一间隙120的延伸方向设置呈夹角，使得中框本体110发生位移的过程中，滑动件210能够相对中框本体110进行滑动，以使分别与两个中框本体110滑动连接的滑动件210之间保持相对稳定，从而保证连接在滑动件210上的结构的稳 定。
需要说明的是，本申请实施例中滑动件210的滑动方向与第一间隙120的延伸方向垂直，有助于中框本体110的移动方向与滑动件210的滑动方向的一致性设计，避免在显示装置10跌落过程中中框本体110与滑动件210出现相互干扰，从而保证显示装置10整体的结构稳定性。
显示装置10包括弹性件300，弹性件300连接在中框本体110与滑动件210之间，以使滑动件210沿远离第一间隙120的方向滑动，即在显示装置10跌落过程中，弹性件300作用于滑动件210上的作用力始终沿远离第一间隙120的方向，避免在中框组件100移动过程中，滑动件210随中框组件100一起朝靠近第一间隙120的方向移动，从而进一步保证滑动组件200的相对稳定性。
此外，将弹性件300连接在中框本体110与滑动件210之间，还能够起到对滑动件210的支撑和缓冲作用，既能避免在显示装置10跌落过程中，滑动件210由于自身重力作用随中框本体110一起移动，也能缓解显示装置10跌落过程中产生的冲击力，从而保证显示装置10整体结构的稳定性。
显示装置10还包括显示屏500，显示屏500连接在滑动组件200背离支撑面111的一侧。其中，所用显示屏500为柔性结构，使得显示屏500能够随着中框组件100的转动而折叠，以满足显示装置10的折叠使用功能。
需要说明的是，由于弹性件300作用于滑动件210上的作用力沿远离第一间隙120的方向，当显示屏500连接到滑动组件200背离支撑面111的一侧后，在滑动件210施加的作用力下，显示屏500两端会受到拉伸的作用力，显示屏500自身具有一定的强度，也会施加给弹性件300朝向第一间隙120的反作用力，从而使弹性件300保持受力平衡，同时，显示屏500在拉伸力的作用下也会保持平整，而不会发生弯曲变形。
本申请实施例通过在显示屏500与中框组件100之间设置滑动组 件200，使得中框本体110能够相对滑动件210发生滑动，同时弹性件300促使滑动件210沿远离两个中框本体110之间的第一间隙120滑动，从而保证在显示装置10发生跌落时，滑动组件200始终对显示屏500具有拉伸作用，防止显示装置10跌落时显示屏500发生变形而出现显示不良。
可选的，如图2和图9所示，滑动件210包括至少两个沿第一间隙120延伸方向依次设置的子滑动件211，子滑动件211与中框本体110滑动连接，即滑动件210通过至少两个子滑动件211与中框本体110在第一间隙120延伸方向上的至少两个位置同时进行滑动连接，此种设置方式既能提高滑动件210与中框本体110滑动过程中的稳定性，也能够增大显示屏500与滑动件210的连接面积以及连接稳定性，从而提高显示装置10整体的结构稳定性。
其中，子滑动件211与中框本体110之间设置有弹性件300，以使子滑动件211沿远离第一间隙120的方向滑动，即每个子滑动件211与中框本体110之间均连接有弹性件300，在同等的条件下，能够降低单个弹性件300上的作用力，从而提高弹性件300的使用寿命。此外，在两个弹性件300的共同作用下，还能够增强显示装置10跌落过程中对滑动件210的缓冲作用，从而提高显示装置10的稳定性。
需要说明的是，在显示装置10使用及跌落过程中，每个子滑动件211受到的对应弹性件300的作用力相等，以确保滑动件210整体和显示屏500的受力均匀性，从而保证显示屏500的结构稳定性，改善显示装置10的显示效果。
可选的，如图4至图6所示，中框本体110的支撑面111上对应子滑动件211的位置开设有第一凹槽112，第一凹槽112沿子滑动件211的滑动方向延伸。子滑动件211面向支撑面111的一侧对应第一凹槽112的位置凸设有第一滑动部212，第一滑动部212插入第一凹槽112内，以使子滑动件211与中框本体110滑动连接。通过在中框本体110的支撑面111上开设第一凹槽112，并将子滑动件211上的第一滑动部212插入第一凹槽112内，使第一滑动部212沿第一凹槽 112滑动，此种结构设计既能对子滑动件211的滑动轨迹进行限定，保证子滑动件211的滑动稳定性，也能减小中框本体110和子滑动件211的厚度之和，从而减小显示装置10的整体厚度。
其中，第一凹槽112能够沿子滑动件211的滑动方向贯穿支撑面111的一侧，且第一凹槽112连续延伸，既能保证第一滑动部212具有足够的滑动空间，也便于子滑动件211与中框本体110的滑动安装。
可选的，第一凹槽112具有相对的两个第一侧壁113，第一侧壁113沿子滑动件211的滑动方向延伸，至少一个第一侧壁113上开设有第一子凹槽114，第一子凹槽114的延伸方向与第一凹槽112的延伸方向一致。第一滑动部212对应第一子凹槽114的位置凸设有第一子滑动部213，第一子滑动部213插入第一子凹槽114内，以使子滑动件211与中框本体110滑动连接。通过第一子凹槽114与第一子滑动部213的配合，能够增强子滑动件211相对中框本体110滑动过程中的稳定性，从而提高显示装置10整体结构的稳定性。
在一些实施例中，只在一个第一侧壁113上开设第一子凹槽114，对应的，第一滑动部212也只在其中一侧凸设第一子滑动部213，即第一凹槽112与第一子凹槽114共同形成L型凹槽，第一滑动部212与第一子滑动部213则共同形成L型滑动部，此种结构设计在保证子滑动件211相对中框本体110滑动时的稳定性的同时，能够简化子滑动件211的结构，提高生产效率。
在另一些实施例中，第一凹槽112的相对两个第一侧壁113上均开设有第一子凹槽114，对应的，第一滑动部212的相对两侧均凸设有第一子滑动部213，即第一凹槽112与第一子凹槽114共同形成T型或工字型凹槽，第一滑动部212与第一子滑动部213则共同形成T型或工字型滑动部，此种结构设计能够进一步增强子滑动件211相对中框本体110滑动时的稳定性。
可选的，如图2所示，本申请实施例中弹性件300的一端与第一凹槽112靠近第一间隙120的侧壁连接，弹性件300的另一端与第一滑动部212靠近第一间隙120的一侧连接，以使第一滑动部212沿远 离第一间隙120的方向滑动。即当将第一滑动部212插入第一凹槽112中时，第一滑动部212靠近第一间隙120的一侧与第一凹槽112的侧壁之间留有间隙，弹性件300则设置在该间隙中，且分别与中框本体110和子滑动件211连接。
由于弹性件300促使子滑动件211沿远离第一间隙120的方向滑动，当所用弹性件300为弹簧时，弹性件300始终处于压缩状态，即在显示装置10使用或跌落过程中，子滑动件211作用于显示屏500上的作用力始终为拉伸力，从而保证显示屏500始终保持平整状态，而不会出现弯曲变形导致显示异常。
在一些实施例中，弹性件300的一端与第一凹槽112远离第一间隙120的侧壁连接，弹性件300的另一端与第一滑动部212远离第一间隙120的一侧连接，以使第一滑动部212沿远离第一间隙120的方向滑动。即当将第一滑动部212插入第一凹槽112中时，第一滑动部212远离第一间隙120的一侧与第一凹槽112的侧壁之间留有间隙，弹性件300设置在该间隙中，且分别与中框本体110和子滑动件211连接。
当所用弹性件300为弹簧时，弹性件300始终处于拉伸状态，即在显示装置10使用或跌落过程中，子滑动件211作用于显示屏500上的作用力始终为拉伸力，从而保证显示屏500始终保持平整状态，而不会出现弯曲变形导致显示异常。
可选的，子滑动件211面向支撑面111的一侧对应第一凹槽112的位置凸设有多个第一滑动部212，多个第一滑动部212沿子滑动件211的滑动方向依次间隔设置，即子滑动件211通过多个第一滑动部212与中框本体110滑动连接，以增强子滑动件211相对中框本体110滑动时的稳定性。
其中，支撑面111上与第一滑动部212对应的第一凹槽112可以为多个，即第一凹槽112与第一滑动部212一一对应，以降低子滑动件211从支撑面111上滑落的风险。当然，支撑面111上开设的第一凹槽112也能够在子滑动件211的滑动方向上连续延伸，即多个第一 滑动部212同时在一个第一凹槽112中滑动，此种设计方式能够简化中框本体110的整体结构，降低生产难度，也有助于子滑动件211与中框本体110的安装。
可选的，弹性件300与靠近第一间隙120的第一滑动部212连接，即在子滑动件211的滑动方向上，能够只在离第一间隙120最近的第一滑动部212与中框本体110之间设置弹性件300，以实现对子滑动件211整体位置的限定。
需要说明的是，当支撑面111上开设有多个第一凹槽112，即第一滑动部212与第一凹槽112一一对应时，能够在每个第一滑动部212靠近第一间隙120的一侧与第一凹槽112靠近第一间隙120的侧壁之间均设置弹性件300，此种结构设计方式既能降低单个弹性件300上的作用力，提高弹性件300的使用寿命，也能够增强弹性件300在显示装置10跌落过程中对滑动件210的整体缓冲作用，提高显示装置10的稳定性。
可选的，第一凹槽112沿远离第一间隙120的方向延伸并贯穿支撑面111边缘，即第一凹槽112沿子滑动件211的滑动方向延伸并贯穿支撑面111的一侧，以便于子滑动件211与中框本体110的安装。第一滑动部212远离第一间隙120的一侧与支撑面111边缘之间具有第二间隙218，以形成子滑动件211相对中框本体110滑动时的滑动空间。
在子滑动件211的滑动方向上，第二间隙218的宽度大于或等于第一间隙120的宽度，在显示装置10跌落过程中，中框本体110的最大移动距离为两个中框本体110之间的第一间隙120的宽度，将第二间隙218的宽度设置为大于或等于第一间隙120的宽度，能够避免在中框本体110相对子滑动件211滑动时，子滑动件211从第一凹槽112中滑落，从而影响显示装置10的结构稳定性及显示效果。
其中，当子滑动件211上设置有多个第一滑动部212，支撑面111上开设有一个第一凹槽112时，第二间隙218是指远离第一间隙120的第一滑动部212与支撑面111边缘之间的间隙。当子滑动件211上 设置有多个第一滑动部212，且支撑面111上开设有多个第一凹槽112时，第二间隙218是指每个第一滑动部212远离第一间隙120的一侧与对应的第一凹槽112侧壁之间的间隙，以确保子滑动件211与中框本体110之间的正常滑动。
可选的，第二间隙218的宽度大于或等于1.5mm且小于或等于2.5mm。若第二间隙218的宽度过小，则会导致中框本体110在相对子滑动件211滑动的过程中，子滑动件211从中框本体110上滑落，甚至导致显示屏500发生弯曲变形，影响显示装置10整体的显示效果；若第二间隙218宽度过大，则会导致显示装置10整体尺寸过大，还会影响显示屏500与中框本体110之间的尺寸匹配，从而影响显示装置10的美观性。
本申请实施例中能够将第二间隙218的宽度设置为1.5mm、1.8mm、2mm、2.3mm或2.5mm等，既能保证中框本体110相对子滑动件211的有效滑动，避免显示屏500发生弯曲变形，也能保证显示装置10整体结构的美观性。其中，第二间隙218的宽度的具体值能够根据实际设计需求进行相应调整，此处不错特殊限制。
可选的，滑动件210包括多个子滑动件211，且多个子滑动件211沿第一间隙120的延伸方向依次间隔设置，中框本体110的支撑面111上对应多个子滑动件211的位置则开设有多个第一凹槽112，以使多个子滑动件211沿对应的第一凹槽112滑动。此种设置方式能够进一步提高滑动件210与中框本体110滑动过程中的稳定性，同时也能够增大显示屏500与滑动件210的连接面积以及连接稳定性，从而提高显示装置10整体的结构稳定性。
其中，每个子滑动件211的具体结构设置以及与支撑面111上对应的第一凹槽112之间的配合方式能够参照上述实施例中的相关描述，此处不再一一赘述。
可选的，如图7所示，子滑动件211面向支撑面111的一侧开设有第二凹槽214，第二凹槽214沿子滑动件211的滑动方向延伸。支撑面111上对应第二凹槽214的位置凸设有第二滑动部115，第二滑 动部115插入第二凹槽214内，以使子滑动件211与中框本体110滑动连接。通过在子滑动件211上开设第二凹槽214，并将中框本体110的支撑面111上的第二滑动部115插入第二凹槽214内，使第二滑动部115沿第二凹槽214滑动，此种结构设计既能对子滑动件211的滑动轨迹进行限定，保证子滑动件211的滑动稳定性，也能减小中框本体110和子滑动件211的厚度之和，从而减小显示装置10的整体厚度。
其中，第二凹槽214能够沿子滑动件211的滑动方向贯穿子滑动件211的一侧，且第二凹槽214连续延伸，既能保证第二滑动部115具有足够的滑动空间，也便于子滑动件211与中框本体110的滑动安装。
可选的，第二凹槽214具有相对的两个第二侧壁215，第二侧壁215沿子滑动件211的滑动方向延伸，至少一个第二侧壁215上开设有第二子凹槽216，第二子凹槽216的延伸方向与第二凹槽214的延伸方向一致。第二滑动部115对应第二子凹槽216的位置凸设有第二子滑动部116，第二子滑动部116插入第二子凹槽216内，以使子滑动件211与中框本体110滑动连接。通过第二子凹槽216与第二子滑动部116的配合，能够增强子滑动件211相对中框本体110滑动过程中的稳定性，从而提高显示装置10整体结构的稳定性。
在一些实施例中，只在一个第二侧壁215上开设第二子凹槽216，对应的，第二滑动部115也只在其中一侧凸设第二子滑动部116，即第二凹槽214与第二子凹槽216共同形成L型凹槽，第二滑动部115与第二子滑动部116则共同形成L型滑动部，此种结构设计在保证子滑动件211相对中框本体110滑动时的稳定性的同时，能够简化子滑动件211的结构，提高生产效率。
在另一些实施例中，第二凹槽214的相对两个第二侧壁215上均开设有第二子凹槽216，对应的，第二滑动部115的相对两侧均凸设有第二子滑动部116，即第二凹槽214与第二子凹槽216共同形成T型或工字型凹槽，第二滑动部115与第二子滑动部116则共同形成T 型或工字型滑动部，此种结构设计能够进一步增强子滑动件211相对中框本体110滑动时的稳定性。
需要说明的是，第二滑动部115与第二凹槽214之间的结构设计和相互配合，以及弹性件300在第二滑动部115与第二凹槽214之间的连接方式能够参考上述实施例中对第一滑动部212与第一凹槽112的相关描述，只需保证中框本体110相对子滑动件211的有效滑动，避免显示装置10使用或跌落过程中因弯曲变形而影响显示屏500的显示效果即可，此处不再一一赘述。
可选的，如图9所示，滑动件210还包括连接部217，连接部217连接在相邻的两个子滑动件211之间，连接部217的延伸方向与第一间隙120的延伸方向一致，即子滑动件211与连接部217连接形成一个整体，以提高滑动件210的结构稳定性，同时也能够提高多个子滑动件211相对中框本体110滑动时的一致性。
其中，子滑动件211与连接部217采用一体成型的方式，以减少显示装置10整体的零件数量，进一步提高滑动件210的结构稳定性，从而保证与滑动件210连接的显示屏500的平整性，改善显示装置10整体的显示效果。
可选的，本申请实施例中中框组件100包括多个沿滑动件210的滑动方向并列设置的中框本体110，任意相邻的两个中框本体110转动连接；对应的，滑动组件200包括多个滑动件210，滑动件210与中框本体110一一对应滑动连接。通过多个中框本体110的转动连接，能够满足显示装置10对不同尺寸及形状的需求，以扩大显示装置10的应用范围。
其中，每个中框本体110与对应的滑动件210之间均采用弹性件300进行连接，以确保各滑动件210之间的相对稳定，从而避免显示装置10在使用或跌落过程中显示屏500发生弯曲变形而影响显示效果。
可选的，如图1和图2所示，显示装置10还包括胶框400，胶框400粘贴在滑动件210背离中框本体110支撑面111的一侧，显示 屏500则粘接在胶框400背离滑动件210的一侧。其中，胶框400的形状能够根据滑动件210的具体形状进行设计，以保证显示屏500与滑动件210的连接稳定性。胶框400可以为双面胶等具有一定延展性的粘接材料，以使显示屏500在滑动件210的拉伸作用下依然能够保持相对稳定。
具体的，以显示装置10包括两个中框本体110为例，在进行跌落测试前，显示装置10的结构如图2所示，两个中框本体110之间具有第一间隙120，对应的滑动件210在弹簧和显示屏500的共同作用下保持相对稳定，且弹簧处于压缩状态。在进行跌落测试时，显示装置10的结构如图3所示，位于上方的中框本体110在冲击力的作用下会向位于下方的中框本体110移动，连接在两个中框本体110之间的转轴会发生变形，直至两个中框本体110相互抵接。
跌落过程中，上方的中框本体110相对滑动件210向下移动，上方中框本体110的移动会带动对应弹簧向下移动，使弹簧长度变长，但弹簧仍然处于压缩状态，相对于上方中框本体110而言，位于上方的滑动件210相对中框本体110向上滑动。此时，由于位于下方的弹簧的压缩程度大于位于上方的弹簧的压缩程度，因此滑动组件200在两个弹簧的共同作用下会整体向下移动，以使两个弹簧的压缩程度一致，从而使滑动组件200能够保持受力平衡。在此过程中，由于两个弹簧始终处于压缩状态，使得显示屏500上下两侧始终受到拉伸力的作用，且两个滑动件210的相对位置不会发生改变，从而能够避免在跌落过程中显示屏500因弯曲变形而出现显示异常。
需要说明的是，本申请实施例中的显示装置10应用范围十分广泛，包括电视机、电脑、移动电话、可折叠以及可卷曲显示器等柔性显示及照明，以及可穿戴设备如智能手环、智能手表等，均在本申请实施例中的显示装置10所属应用领域范围内。
