承载箱体和拼接显示装置 技术领域
本公开涉及显示领域，特别涉及一种承载箱体和拼接显示装置。
背景技术
大型显示屏幕通常由多个子显示面板组件进行矩阵排列拼接构成，依靠每一子显示面板组件的播放画面进行组合形成整体的大型显示屏幕的画面。

具体实施方式
为使本领域技术人员更好地理解本公开的技术方案，下面结合附图和具体实施方式对本公开作进一步详细描述。
以下将参照附图更详细地描述本公开。在各个附图中，相同的元件采用类似的附图标记来表示。为了清楚起见，附图中的各个部分并没有 都按比例绘制。此外，在图中可能未示出某些公知的部分。
在下文中描述了本公开的许多特定的细节，例如部件的结构、材料、尺寸、处理工艺和技术，以便更清楚地理解本公开。但正如本领域的技术人员能够理解的那样，可以不按照这些特定的细节来实现本公开。
图1A为本公开实施例所涉及承载箱体的一种结构示意图。图1B为本公开实施例中承载箱体与子显示面板组件进行装配前的一种结构示意图。图2为本公开实施例所涉及拼接显示装置的一种结构示意图。图3为本公开实施例所涉及拼接显示装置的一种爆炸结构示意图。如图1至图3所示，承载箱体包括：箱体主体2和至少一个拼缝调节结构组件3。
其中，箱体主体2用于承载多个子显示面板组件1；每个拼缝调节结构组件3对应相邻设置的两个子显示面板组件1，拼缝调节结构组件3与箱体主体2连接，拼缝调节结构组件3用于调节对应相邻设置的两个子显示面板组件1之间的拼缝宽度。
在本公开实施例中，通过箱体主体2上拼缝调节结构组件3可以调节所对应相邻设置的两个子显示面板组件1之间的拼缝宽度，整个过程无需将子显示面板组件1从承载箱体上拆卸下来，可有效避免子显示面板组件1之间发生磕碰、子显示面板组件1出现损伤的问题，从而可降低拼接显示装置的成本，提高拼接显示装置的良率。同时，通过拼缝调节结构组件3的调节，可提高所对应相邻设置的两个子显示面板组件1之间的拼接精度，有利于提高拼接显示装置的显示性能。
图4为本公开实施例中子显示面板组件的一种结构示意图。图5为本公开实施例中子显示面板组件的一种俯视示意图。图6为本公开实施例所涉及子显示面板组件的一种爆炸结构示意图。图7为本公开实施例中拼缝调节结构组件处的一种截面示意图。图8为图7中区域A的局部放大示意图。如图4至图8所示，在一些实施例中，子显示面板组件1包括：显示基板11和固定框架12。
其中，显示基板11固定于固定框架12的一侧；箱体主体2包括底板22和支撑结构24，支撑结构24位于底板22的一侧，支撑结构24用于承载子显示面板组件1，底板22配置为与子显示面板组件1相对设置；拼缝调节结构组件3位于底板22上且配置为能够与对应相邻设置的两个子显示面板组件1内固定框架12相接触，以调节对应相邻设置的两个子显示面板组件1内固定框架12之间的间距。
也就是说，在本公开实施例中，通过拼缝调节结构组件3与对应相邻设置的两个子显示面板组件1内固定框架12相接触，并对对应相邻设置的两个子显示面板组件1内固定框架12之间的间距进行调节，从而实现对相邻设置的两个子显示面板组件1之间的拼缝宽度的调节。
在一些实施例中，显示基板11的衬底材料可为玻璃、聚酰亚胺(PI)或者其他适合的材料。
具体的，该拼接显示装置的子显示面板组件1可为液晶子显示面板组件、有机发光二极管(OLED)子显示面板组件，优选的子显示面板组件1为微型无机发光二极管子显示面板组件。
在一些实施例中，拼缝调节结构组件3配置为能够沿底板22的法线方向进行运动，且能够伸入至对应相邻设置的两个子显示面板组件1内固定框架12之间，并与对应相邻设置的两个子显示面板组件1内固定框架12的外侧壁12A相接触。
在本公开实施例中，通过拼缝调节结构组件3伸入至对应相邻设置的两个子显示面板组件1内固定框架12之间，并对相邻设置的两个子显示面板组件1内固定框架12的外侧壁12A进行挤压，以使得对应相邻设置的两个子显示面板组件1内固定框架12之间的间距发生变化，从而实现对固定框架12之间的间距的调节。
在一些实施例中，拼缝调节结构组件3包括：顶杆31，顶杆31包括：杆体301和伸入部302，杆体301贯穿底板22，伸入部302固定于 杆体301靠近子显示面板组件1的一端；在沿着靠近杆体301的方向上，伸入部302在平行于底板22的截面的截面面积逐渐增大；伸入部302的部分外侧壁配置为与对应相邻设置的两个子显示面板组件1内固定框架12的外侧壁12A相接触。
其中，在一定范围(由伸入部302的外侧壁形貌、子显示面板组件1内固定框架12的外侧壁12A的形貌所决定)内，伸入部302伸入至对应相邻设置的两个子显示面板组件1内固定框架12之间的深度越深，则所对应相邻设置的两个子显示面板组件1内固定框架12之间的间距越大。
图9为本公开实施例中不同伸入部与所接触的两个固定框架的多种结构示意图。如图9所示，在一些实施例中，伸入部302在垂直于底板22的截面的截面形状为三角形(参见图9中(a)和)(b)中所示情况)或等腰梯形(参见图9中(c)和)(d)中所示情况)；在一些实施例中，子显示面板组件1内固定框架12的外侧壁12A上用于与对应的拼缝调节结构组件3内伸入部302相接触的部分为竖直面(参见图9中(a)和)(c)中所示情况)或坡度角β为锐角的斜坡面(参见图9中(b)和)(d)中所示情况)。
需要说明的是，图9中所示情况仅起到示例性左右，其不会对本公开的技术方案产生限制；在公开实施例中伸入部302在垂直于底板22的截面的截面形状还可以采用其他形状(例如，将图中等腰梯形的腰设计为曲线)、子显示面板组件1内固定框架12的外侧壁上用于与对应的拼缝调节结构组件3内伸入部302相接触的部分也可以为其他形貌(例如，将外侧壁上用于与对应的拼缝调节结构组件3内伸入部302相接触的部分设计为曲面)。在本公开实施例中，仅需保证在一定范围(根据实际需要来设计)内，伸入部302伸入至对应相邻设置的两个子显示面板组件1内固定框架12之间的深度越深，可使得所对应相邻设置的两个 子显示面板组件1内固定框架12之间的间距越大即可。
在一些实施例中，伸入部302的形状为圆锥形、四棱锥形、圆台形或四棱台形。
在一些实施例中，拼缝调节结构组件3还包括：伸入定位结构32，底板22上对应拼缝调节结构组件3位置形成有第一限位槽23，第一限位槽23配置为容纳伸入定位结构32并将伸入定位结构32限位于不同深度；第一限位槽23的底部形成有过孔，杆体301贯穿过孔，伸入定位结构32与杆体301远离伸入部302的一端相连。
在本公开实施例中，可通过伸入定位结构32来推动杆体301进行运动，从而对伸入部302的伸入深度进行控制，以实现对所对应相邻设置的两个子显示面板组件1内固定框架12之间的间距的控制。
作为一个示例，当需要增大某相邻设置的两个子显示面板组件1之间的拼缝宽度时，可通过对应的伸入定位结构32来推动杆体301朝子显示面板组件1进行运动，此时伸入部302的伸入深度变深，该相邻设置的两个子显示面板组件1内固定框架12之间的间距增大，从而实现该相邻设置的两个子显示面板组件1之间的拼缝宽度增大。
作为另一个示例，当需要减小某相邻设置的两个子显示面板组件1之间的拼缝宽度时，可将伸入定位结构32从第一限位槽23内抽出部分并进行固定(由第一限位槽23进行限位固定)。此时，存在两种情形：
情形一，若伸入定位结构32与杆体301远离伸入部302的一端固定相连，则伸入定位结构32带动杆体301朝远离子显示面板组件1的一侧运动，此时可适当的对该相邻设置的两个子显示面板组件1朝拼缝的方向进行挤压，拼缝宽度不断减小，直至该相邻设置的两个子显示面板组件1内固定框架12与伸入部302相接触，拼缝宽度不再变化。
情形二，若伸入定位结构32与杆体301远离伸入部302的一端非固定相连，则杆体301远离伸入部302的一端与伸入定位结构32分离，此 时可适当的对该相邻设置的两个子显示面板组件1朝拼缝的方向进行挤压，该相邻设置的两个子显示面板组件1内固定框架12推动杆体301朝远离子显示面板组件1的一侧运动，拼缝宽度不断减小，直至该杆体301远离伸入部302的一端与伸入定位结构32相接触，拼缝宽度不再变化。
在一些实施例中，伸入定位结构32包括调节螺丝，第一限位槽23的内侧壁形成有与调节螺丝的外螺纹相匹配的内螺纹。也就是说，可通过旋转调节螺丝可控制调节螺丝置于容纳槽内的长度，从而能够对伸入部302的伸入深度进行控制。
在本公开实施例中，通过调节螺丝可对伸入部302的伸入深度进行精准控制；另外，在安装人员通过调节螺丝对伸入部302的伸入深度进行调节的过程中，安装人员还可以同时从拼接显示装置的正面观察调节效果。
图10为本公开实施例中拼缝调节结构组件的一种截面示意图。如图10所示，在一些实施例中，顶杆31还包括：限位部303，限位部303固定于杆体301远离伸入部302的一端；拼缝调节结构组件3还包括：弹性部件33，弹性部件33的一端与限位部303相连，弹性部件33的另一端与第一限位槽23的底部相连。其中，弹性部件33始终处于压缩状态。此时，在将伸入定位结构32从第一限位槽23内抽出部分后，即便伸入定位结构32与杆体301远离伸入部302的一端非固定相连，但在弹性部件33的作用下，限位部始终是与便伸入定位结构32相连，也就是说杆体301会跟随伸入定位结构32朝远离子显示面板组件1的一侧运动，此后仅需按照情形一中所描述，适当的对该相邻设置的两个子显示面板组件1朝拼缝的方向进行挤压，直至该相邻设置的两个子显示面板组件1内固定框架12与伸入部302相接触。
在一些实施例中，调节螺丝的直径为3mm～5mm，调节螺丝的长度为 4mm～6mm(顶杆31的移动距离为4mm～6mm)；顶杆31的长度为8mm～12mm。
基于同一发明构思，本公开实施例还提供了一种拼接显示装置，该拼接显示装置包括：多个子显示面板组件和承载箱体，其中该承载箱体可采用上述实施例中所提供的承载箱体，对于承载箱体的具体描述可参见前面实施例中的内容。
在一些实施例中，相邻设置的两个子显示面板组件1所配置的拼缝调节结构组件3的数量为1个或多个。也就是说，相邻设置的两个子显示面板组件1之间的拼缝宽度可通过对应的1个或多个拼缝调节结构组件3来进行调节。
在一些实施例中，任意相邻设置的两个子显示面板组件1均配置有对应的拼缝调节结构组件3。也就是说，任意相邻设置的两个子显示面板组件1之间的拼缝宽度均可通过对应的拼缝调节结构组件3来进行调节。
在一些实施例中，子显示面板组件1包括：显示基板11和固定框架12，显示基板11固定于固定框架12的一侧；箱体主体2包括底板22和支撑结构24，支撑结构24位于底板22的一侧，支撑结构24用于承载子显示面板组件1，底板22配置为与子显示面板组件1相对设置；拼缝调节结构组件3位于底板22上且配置为能够与对应相邻设置的两个子显示面板组件1内固定框架12相接触，以调节对应相邻设置的两个子显示面板组件1内固定框架12之间的间距；此时，相邻设置的两个子显示面板组件1所配置的拼缝调节结构组件3的数量为1个，拼缝调节结构组件3位于对应相邻设置的两个子显示面板组件1内固定框架12之间的中间位置。
参见图3所示，该拼接显示装置包括沿第一方向X和第二方向Y呈阵列2×4排布的8个子显示面板组件1-1～1-4、2-1～2-4。针对该8 个子显示面板组件1-1～1-4、2-1～2-4，配置有10个拼缝调节结构组件3，分别处于图3中Q1～Q10所在区域；其中，任意相邻设置的两个子显示面板组件均配置有对应的1个拼缝调节结构组件3。
作为一个示例，图3中沿第一方向X相邻设置的子显示面板组件1-1与子显示面板组件1-2，二者所对应的拼缝调节结构组件3位于二者固定框架12之间的中间位置Q1，通过该拼缝调节结构组件3可调节子显示面板组件1-1与子显示面板组件1-2在第一方向X上进行微移，以对子显示面板组件1-1与子显示面板组件1-2之间的间隙宽度进行调节。
作为另一个示例，图3中沿第二方向Y相邻设置的子显示面板组件1-1与子显示面板组件2-1，二者所对应的拼缝调节结构组件3位于二者固定框架12之间的中间位置Q4；通过该拼缝调节结构组件3可调节子显示面板组件1-1与子显示面板组件2-1在第二方向Y上进行微移，以对子显示面板组件1-1与子显示面板组件2-1之间的间隙宽度进行调节。
在一些实施例中，固定框架12的外侧壁12A上设置有磁铁4，相邻设置的两个子显示面板组件1内固定框架12的相对外侧壁所设置的磁铁4分别具有相吸的磁性。也就是说，相邻设置的两个子显示面板组件1内固定框架12通过磁铁4相吸，可使得在所对应的拼缝调节结构组件3内的伸入部302伸入至对应的两个固定框架12之间时，该两个固定框架12始终保持能够对伸入部302产生挤压作用力(该相邻设置的两个子显示面板组件1内的固定框架12朝拼缝的方向进行自动挤压)。
参见图6所示，在一些实施例中，拼接显示装置还包括：第一线路板6，位于固定框架12远离显示基板11的一侧，第一线路板6与固定框架12活动连接。第一线路板6具有第一连接端口61。
此外，拼接显示装置还包括：第二线路板(未示出)，固定在箱体主体2的安装面(未示出)上，第二线路板与第一线路板6固定连接，例如第二线路板可以为多端口转发器。
其中，第一线路板6被配置为向子显示面板组件1传输数据信号，以形成子显示面板组件1的显示画面，具体地，子显示面板组件1中包括设置于显示基板11非显示侧的3个柔性电路板FPC1、FPC2、FPC3，第一线路板6中的第一接线口62、第二接线口63、第三接线口64分别与FPC1、FPC2、FPC3电气连接。固定框架12用于固定显示基11，即固定框架12和显示基板11两者是固定安装的。第一线路板6与第二线路板电连接，第二线路板可以通过第一线路板6向子显示面板组件1中的显示基板11提供数据信号。固定框架12与第一线路板6活动连接，这样第一电路板与显示基板11活动连接。
需要说明的是，第二线路板上具有与第一线路板6的第一连接端口61固定连接的第二连接端口。第二线路板可位于第二连接端口所在结构板的背离第二连接端口的一侧。
在一些实施例中，第一线路板6可为PCB板，固定框架12的形成材料可为压铸铝、铝合金，或者其他适合的材料。
第一线路板6包括：至少一个第二限位槽131；固定框架12上设置有：至少一个第二定位柱135，和至少一个第三螺纹孔136和至少一个固定孔132。其中，第二限位槽131的数目与第二定位柱135和第三螺纹孔136的数目之和相同。第二定位柱135用于与部分第二限位槽131装配，以实现第一线路板6与固定框架12的装配对位；而第二限位槽131和第三螺纹孔136通过螺纹连接件133连接，以实现第一线路板6与固定框架12的装配固定；其中，螺纹连接件133包括弹簧垫片134。
在一些实施例中，第一线路板6的第二限位槽131和固定框架12的第三螺纹孔136通过螺栓和螺母连接，并且螺栓和螺母之间具有弹簧垫片134，弹簧垫片134对第一线路板6和固定框架12之间的连接具有缓冲作用。弹簧垫片134可为压缩弹簧。
每个子显示面板组件1还包括：铁磁材料片8，在拆卸拼接显示装 置中的子显示面板时，可以通过带有磁性的静电吸盘，将子显示面板从承载箱体上分离。其中，磁材料片8上设置有与固定框架12上设置的固定孔132一一对应的安装孔137，利用固定孔132和安装孔137通过固定件(例如螺钉)实现磁材料片8和固定框架12的装配连接。
箱体主体2上划分有与子显示面板组件1一一对应的多个安装区域，每个安装区域内设置有相应的安装面。子显示面板组件1与箱体主体2的安装过程大致如下：
对于每一个子显示面板组件1而言，在子显示面板组件1固定安装在箱体主体2对应的安装区域之前，首先需将与各个子显示面板组件1对应连接的第一线路板6进行装配。在一些实施例中，第一线路板6上的一部分第二限位槽131与子显示面板组件1的固定框架12上的第二定位柱135相互卡合装配(即第二定位柱135伸入对应的第二限位槽131中)，第一线路板6上的其余第二限位槽131与子显示面板组件1的固定框架12上的第三螺纹孔136通过螺栓和螺母连接，此时，螺栓和螺母可以进行初步地紧固，以实现子显示面板组件1与第一线路板6的连接即可。由于第二限位槽的斜向设计以及第二限位槽截面积大于的螺栓、螺母以及第二定位柱的截面，故螺栓、螺母和第二定位柱均可以沿其所在槽体滑动，即子显示面板组件1与第一线路板6之间可以实现沿第二限位槽131的槽体所在区域的相对移动。
接着，将装配有第一线路板6的子显示面板组件1与箱体主体2进行装配：第一线路板6的第一连接端口61与设置在箱体主体2的第二线路板的第二连接端口固定连接。
再接着，利用拼缝调节结构组件3对所对应的相邻设置的两个子显示面板组件1之间的拼缝宽度进行调节。在此过程中，由于微调结构组件位于固定框架12上，并且显示基板11与第一线路板6活动连接，因此对子显示面板组件1的微调并不会影响第一线路板6与第二线路板的 之间的电连接。
在一些实施例中，子显示面板组件1的固定框架12在朝向箱体主体2的一侧上设置有平头钉82，而箱体主体2的安装面在对应每个子显示面板组件1的每个区域中对应设置有多个磁性结构81。例如，图4和图5所示情况中每个子显示面板组件1上设置有6个平头钉82，箱体主体2的对应区域设置有8个磁性结构81。平头钉82的材料可以包括如铁、镍、钴、铁质镀锌、不锈铁等铁磁金属或铁磁合金材料；由于磁性结构81具有磁力，故可以向安装有平头钉的子显示面板提供磁性吸附力。可以理解的是，考虑装配公差和工件尺寸公差，在子显示面板组件1安装到箱体主体2上后，磁性结构81与平头钉82在显示基板的发现方向上可以具有不超过0.3mm的间距。箱体主体2中磁性结构81可以为各个子显示面板组件1提供可靠的吸附力，从而使得拼接显示装置具有较高的可靠性。
