 有益效果
本申请通过在现有的折叠显示装置的铰链的转轴的位置处增加一散热结构，并在散热结构的基材的侧壁上设置有连通孔，连通孔可以连通散热结构的基材层的底壁和侧壁构成的第一收容空间和柔性屏和中框(第一中框和第二中框)之间第二收容空间和第三收容空间，从而使得折叠显示装置的内部空间实现整机连通，如此，可以平衡折叠显示装置的整机热量，使整机热量均匀分散；2)散热结构带有散热叶片，在所述折叠显示装置折叠或展开时，散热叶片会沿铰链的转轴的轴向推送空气，并且形成局部负压，此时，第二收容空间和第三收容空间内的空气会通过连通孔被大气压挤进散热结构的第一收容空间内，形成流动的气流，带走第二收容空间和第三收容空间内的热量，提高了整机内部空气的流通率，达到良好的整机散热效果；3)采用金属(例如：铜)制作散热结构的基材层并在基材层的面向铰链的表面上形成石墨烯层(第一石墨烯层和第二石墨烯层)，由于铜具有良好的导热性能且铜的Z向导热效率很高，因此，第二收容空间和第三收容空间内的热量还可以通过基材层快速转移到石墨烯层，增加了热传导散热速率；另外，将石墨烯层设置在散热结构的基材层上增加了石墨烯层的热辐射的表面积，从而提高了整体热辐射散热效率；4)两种散热方式相结合，不仅能够达到良好的整机散热效果，从而减少烧屏、亮度不均等不良，以保护折叠显示装置内部的电子元器件等，提高折叠显示装置的寿命并改善用户体验。

 本发明的实施方式
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。
在本申请的描述中，需要理解的是，术语“上”、“下”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
本申请可以在不同实施中重复参考数字和/或参考字母，这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施方式和/或设置之间的关系。
本申请针对现有的折叠显示装置能够贴附石墨的区域较少，导致通过热辐射散热的效率不高；并且折叠显示装置的上下中框被转轴分隔开，内部空间联通性不好，极易造成热量分布不均的技术问题，本申请通过在现有的折叠显示装置的铰链的转轴的位置处增加一散热结构，并在散热结构的基材的侧壁上设置有连通孔，连通孔可以连通散热结构的基材层的底壁和侧壁构成的第一收容空间和柔性屏和中框(第一中框和第二中框)之间第二收容空间和第三收容空间，从而使得折叠显示装置的内部空间实现整机连通，如此，可以平衡折叠显示装置的整机热量，使整机热量均匀分散；2)散热结构带有散热叶片，在所述折叠显示装置折叠或展开时，散热叶片会沿铰链的转轴的轴向推送空气，并且形成局部负压，此时，第二收容空间和第三收容空间内的空气会通过连通孔被大气压挤进散热结构的第一收容空间内，形成流动的气流，带走第二收容空间和第三收容空间内的热量，提高了整机内部空气的流通率，达到良好的整机散热效果；3)采用金属(例如：铜)制作散热结构的基材层并在基材层的面向铰链的表面上形成石墨烯层(第一石墨烯层和第二石墨烯层)，由于铜具有良好的导热性能且铜的Z向导热效率很高，因此，第二收容空间和第三收容空间内的热量还可以通过基材层快速转移到石墨烯层，增加了热传导散热速率；另外，将石墨烯层设置在散热结构的基材层上增加了石墨烯层的热辐射的表面积，从而提高了整体热辐射散热效率。
请参阅图1至图5，本申请较佳实施例提供了一种折叠显示装置100，所述折叠显示装置100包括柔性屏(图未示)、第一中框20、第二中框30、铰链(图未示)、电子元器件(图未示)及散热结构10。所述铰链的两端分别固定在所述第一中框20和所述第二中框30上且能够带动所述第一中框20和所述第二中框30相对于所述铰链的转轴折叠或展开。所述柔性屏位于所述铰链上方，所述柔性屏的两端分别固定在所述第一中框20和所述第二中框30上。所述散热结构10位于所述第一中框20和所述第二中框30之间且固定在所述铰链的转轴上。所述散热结构10可以作为所述铰链的转轴盖。所述柔性屏和第一中框20构成一第二收容空间102，所述柔性屏和所述第二中框30构成一第三收容空间103。

在本实施例中，所述底壁111、所述第一侧壁112及所述第二侧壁113一体成型。在其他实施例中，所述底壁111、所述第一侧壁112及所述第二侧壁113还可以通过粘结剂或机械结构连接在一起。
其中，所述第一侧壁112及所述第二侧壁113分别呈弧形，所述第一侧壁112及所述第二侧壁113的弧形的圆心位于所述第一收容空间101内。
其中，定义所述底壁111的长度方向为D1，其中，所述底壁111的长度方向与所述铰链的转轴的轴向方向一致。多个所述第一连通孔14沿所述底壁111的长度方向D1设置在所述第一侧壁112上，多个所述第二连通孔15沿所述底壁111的长度方向D1设置在所述第二侧壁113上。
其中，所述散热结构10还包括至少一个固定块13，所述固定块13沿所述底壁111的长度方向D1等间距或不等间距设置在所述底壁111上。
其中，每个所述固定块13上具有一个固定孔131，所述固定孔131用于固定铰链的转轴。具体地，所述固定孔131用于配合一与之匹配的插销或螺钉固定所述铰链的转轴。
其中，所述散热结构10还包括多个散热叶片12，多个所述散热叶片12收容在所述第一收容空间101内且等间距或不等间距设置在所述底壁111上。优选地，多个所述散热叶片12等间距设置在所述底壁111上。

由于所述固定块13及所述散热叶片12均设置在所述底壁111上，因此，相邻两个固定块13之间具有至少一个所述散热叶片12。
其中，所述散热结构10还包括第一石墨烯层16和第二石墨烯层17，所述第一石墨烯层16形成在所述第一侧壁112上，所述第二石墨烯层17形成在所述第二侧壁113上。所述第一石墨烯层16及所述第二石墨烯层17位于所述第一收容空间101内。所述第一连通孔14还贯穿所述第一石墨烯层16，所述第二连通孔15还贯穿所述第二石墨烯层17。
本申请通过在现有的折叠显示装置的铰链的转轴的位置处增加一散热结构，并在散热结构的基材的侧壁上设置有第一连通孔14和第二连通孔15，第一连通孔14和第二连通孔15连通散热结构10的第一收容空间101和由柔性屏和第一中框20构成的第二收容空间102以及由柔性屏和第二中框30构成的第三收容空间103，从而使得折叠显示装置100的内部空间实现整机连通，如此，可以平衡折叠显示装置100的整机热量，使整机热量均匀分散。
所述散热结构10带有所述散热叶片12，在所述折叠显示装置100折叠或展开时，所述散热叶片12会沿铰链的转轴的轴向推送空气，并且形成局部负压，此时，第二收容空间102和第三收容空间103内的空气会分别通过所述第一连通孔14和所述第二连通孔15被大气压挤进所述散热结构的第一收容空间101内，形成流动的气流，进而带走所述第二收容空间102和所述第三收容空间103内的热量，达到良好的整机散热效果。
本申请提供的折叠显示装置100采用金属(例如：铜)制作所述散热结构10的基材层11并在基材层11的面向铰链的表面上形成第一石墨烯层16和第二石墨烯层17，由于铜具有良好的导热性能且铜的Z向导热效率很高，因此，所述第二收容空间102和所述第三收容空间103内的热量还可以通过所述基材层11快速转移到所述第一石墨烯层16和所述第二石墨烯层17。另外，由于所述第一石墨烯层16和所述第二石墨烯层17设置在了所述散热结构10的基材层11上，从而增加了石墨烯的热辐射的表面积，可以更加快速的将热量辐射出去。
请参次参阅图1，所述第一中框20设置有多个第二固定孔21和多个第三固定孔22，所述第二固定孔21用于固定所述电子元器件，所述第三固定孔22用于固定所述铰链的可相对其转轴翻转的一侧。所述第三固定孔22靠近所述散热结构10。所述第二中框30设置有多个第四固定孔31和多个第五固定孔32，所述第四固定孔31用于固定所述电子元器件，所述第五固定孔32用于固定所述铰链的可相对其转轴翻转的另一侧。所述第五固定孔32靠近所述散热结构10。

综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
