为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图来对本发明提供的承载箱体的拼装件和拼接显示装置进行详细描述。
请参阅图1A和图1B，承载箱体1用于承载至少一个显示模组，具体地，显示模组可以通过粘接或者磁吸的方式固定在承载箱体1上。多个承载箱体1拼接组装在一起，以使多个显示模组能够拼接形成大尺寸 的显示屏。例如，如图1A所示，单个承载箱体1包括背板12，该背板12具有朝向显示模组的第一表面，且在该第一表面的边缘处围绕设置有多条侧边，多条侧边的远离上述第一表面的端面用作安装显示模组的安装面(即，图3中示出的侧边11的端面111)，即，显示模组与该安装面相抵。以承载箱体1为矩形箱体为例，上述第一表面为矩形，且侧边为四条，分别为第一侧边11a、第二侧边11b、第三侧边11c和第四侧边11d，其中，第一侧边11a和第二侧边11b相互连接，且在相接的位置处形成一边角；第一侧边11a和第四侧边11d相互连接，且在相接的位置处形成一边角；第三侧边11c和第二侧边11b相互连接，且在相接的位置处形成一边角；第三侧边11c和第四侧边11d相互连接，且在相接的位置处形成一边角，即，矩形的承载箱体1共形成四个边角。并且，在每个承载箱体1的上述第一表面所在一侧，且位于每个边角处均设置有连接结构2。在实际应用中，承载箱体1并不局限于采用矩形箱体，也可以采用其他四边形形状的箱体。
而且，如图1B所示，多个承载箱体1在平行于上述安装面的平面内的X1方向和X2方向上呈矩阵排布，且在X1方向和X2方向上的数量均为4个，当然，在实际应用中，多个承载箱体1可以根据具体需要选择排布方式和数量。
在本实施例中，如图1B所示，至少两个承载箱体1相邻设置，且在相邻设置的承载箱体1的毗邻设置的侧边上的连接结构2，构成连接结构组，例如，两个相邻的承载箱体1的毗邻设置的侧边上的连接结构2组成第一连接结构组20a，四个相邻的承载箱体1的毗邻设置的侧边上的连接结构2组成第二连接结构组20b。其中，每个连接结构组中的不同的连接结构2属于不同的承载箱体1。
当然，在实际应用中，根据排布方式的不同，也可能存在有相邻的三个承载箱体1的情况，在这种情况下，三个相邻的承载箱体1的毗邻设置的侧边上的连接结构2组成第三连接结构组。
在一些实施例中，可选的，同一连接结构组中至少包括相对于第一平面呈轴对称排布的两个连接结构2，其中，该第一平面平行于相邻设置的承载箱体1的毗邻设置的侧边所在平面。具体来说，对于第一连接结构组20a，其有相邻的两个连接结构2，二者呈轴对称排布；对于第二连接结构组20b，其有相邻的四个连接结构2，四者呈轴对称排布。这样设置，可以实现相同的组装结构兼容不同数量的连接结构2组成的连接结构组。
请参阅图2，本实施例提供的拼装件3，其位于承载箱体1的上述背板12的第一表面所在一侧，即，与显示模组相对的一侧，并且，拼装件3与上述连接结构组中的所有连接结构2连接，具体来说，拼装件3既能够与第一连接结构组20a中的两个连接结构2连接，又能够与第二连接结构组20b中的四个连接结构2连接，即能够兼容连接结构2的数量不同的两种连接结构组。并且，拼装件3被设置为能够调整上述连接结构组中的连接结构2对应的侧边上的安装面之间的平整度，即，能够通过调节使相邻的至少两个承载箱体1对应的上述安装面相平齐。
由于上述拼装件3位于承载箱体1的用于安装显示模组的安装面一侧，这可以使安装和调试人员在箱体前侧进行拼接操作，从而可以适用于箱体背面没有足够的安装空间的场景，提高安装便捷性。
上述拼装件3可以有多种结构，例如，在本实施例中，如图2和图3所示，拼装件3包括连接板31和紧固件32(由图2中的虚线框表示)，其中，每个连接结构2均包括与连接板31相对的第一调平面211，该第 一调平面211与上述安装面相互平行；连接板31包括第二调平面311，该第二调平面311与上述连接结构组中的所有连接结构2的第一调平面211相对。例如，对于第一连接结构组20a，第二调平面311与相邻的两个连接结构2的第一调平面211相对；对于第二连接结构组20b，第二调平面311与相邻的四个连接结构2的第一调平面211相对。
上述紧固件32用于将上述连接结构组中的各个连接结构2与连接板31固定连接，并使该连接结构组中的各个连接结构2的第一调平面211均与第二调平面311相贴合，从而可以保证相邻的至少两个承载箱体1对应的上述安装面的平整度。
紧固件32将连接结构2与连接板31固定连接的方式可以有多种，例如，如图3所示，紧固件32与对应的连接结构2采用螺纹连接的方式固定连接，且该紧固件32被设置为向连接板31施加使上述第一调平面211均与上述第二调平面311相贴合的压力，该压力能够保证第一调平面221与第二调平面311保持贴合。
紧固件32包括多个紧固螺钉321，且上述连接结构组中的每个连接结构2与至少一个紧固螺钉321螺纹连接，其中，例如，如图2和图3所示，紧固件32包括四个紧固螺钉321，对于第一连接结构组20a，其有相邻的两个连接结构2，在这种情况下，有两个紧固螺钉321与其中一个连接结构2螺纹连接，其余两个紧固螺钉321与其中另一个连接结构2螺纹连接，即，每个连接结构2与两个紧固螺钉321螺纹连接。对于第二连接结构组20b，其有相邻的四个连接结构2，在这种情况下，四个连接结构2一一对应地与四个紧固螺钉321螺纹连接，即，一个连接结构2连接一个紧固螺钉321。由上可知，连接结构组中的连接结构的数量不同，分配至各个连接结构的紧固螺钉321的数量也不同。
在本实施例中，紧固螺钉321的螺钉头位于连接板31的背离上述第二调平面311的一侧，紧固螺钉321的螺柱贯穿连接板31，并与对应的连接结构2螺纹连接。当紧固螺钉321旋紧时，其会向连接板31施加使上述第一调平面211均与上述第二调平面311相贴合的压力，以保证第一调平面221与第二调平面311保持贴合；同时，通过调整紧固螺钉321的给进量，以使所有的第一调平面221均能够与第二调平面311保持贴合，从而可以实现对不同的箱体之间的平整度的调整。
在一些实施例中，可选的，请参阅图3和图4A，每个连接结构2均设置在背板12的第一表面上，且位于由两个侧边11构成的边角处，该连接结构2可以有多种结构，在一些优选的实施例中，连接结构2包括多个连接柱21，每个连接柱21的一端与背板12的第一表面连接，每个连接柱21的远离该第一表面的另一端的端面用作第一调平面211，即，多个连接柱21的另一端的端面是平齐的，以共同构成该第一调平面211。并且，在每个连接柱21的第一调平面211上均设置有一个螺纹孔22，该螺纹孔22的轴线与连接柱21的轴线重合，二者例如均与上述背板12的第一表面相互垂直。
上述多个连接柱21上的螺纹孔22中有至少一个螺纹孔22用于与对应的上述紧固螺钉321的螺柱螺纹连接。例如，如图4A所示，连接结构3包括三个连接柱21，每个连接柱21的一端均与背板12的第一表面连接，每个连接柱21的远离该第一表面的另一端的端面均用作第一调平面211。在每个连接柱21的第一调平面211上均设置有一个上述螺纹孔22，即，三个连接柱21中分别形成有三个螺纹孔22。在这种情况下，对于第一连接结构组20a，其有相邻的两个连接结构2，在这种情况下，有两个紧固螺钉321与其中一个连接结构2中对应的两个螺纹孔 22螺纹连接，其余两个紧固螺钉321与其中另一个连接结构2中的对应的两个螺纹孔22螺纹连接，即，每个连接结构2中三个螺丝孔22中的两个分别与两个紧固螺钉321螺纹连接，而剩余的一个螺纹孔22没有起连接作用。对于第二连接结构组20b，其有相邻的四个连接结构2，在这种情况下，四个连接结构2中三个螺纹孔22中的一个分别与四个紧固螺钉321螺纹连接，即，一个紧固螺钉321与其中一个连接结构2中对应的一个螺纹孔22螺纹连接，四个螺纹孔22均起到连接作用。由上可知，连接结构组中的连接结构的数量不同，起到连接作用的螺纹孔22的数量也不同。
需要说明的是，上述连接结构3并不局限于本实施例中采用的多个连接柱，在实际应用中，上述连接结构3也可以由其他任意结构的的多个连接件构成，或者上述连接结构3还可以采用一体式结构，至少一个螺纹孔22均设置在该一体式结构中。
在一些实施例中，可选的，连接柱21与背板12一体成型，例如采用压铸的方式一体成型。
在本实施例中，如图4A和图4B所示，在承载箱体1的每一边角处，连接柱21为三个，且对应地，螺纹孔22为三个。例如，如图4B所示，三个螺纹孔22分别为第一螺纹孔22a、第二螺纹孔22b和第三螺纹孔22c，且第一螺纹孔22a、第二螺纹孔22b和第三螺纹孔22c在第一调平面211上的正投影的中心连线构成等腰直角三角形，且该等腰直角三角形的两个直角边分别与构成边角的两个侧边(11a，11b)相互平行。这样设置，可以使构成边角的两个侧边(11a，11b)所对应的螺纹孔的数量和位置相同，从而无论是两个侧边(11a，11b)中的哪一个侧边与其他承载箱体1的相应侧边拼接，螺纹孔的数量和位置都是一致的， 即，呈轴对称排布，进而实现各连接结构组的拼接方式是一致的。
在这种情况下，对于任意两个相邻的承载箱体1，与二者的毗邻设置的侧边相邻的四个螺纹孔22在第一调平面221上的正投影的中心连线构成第一正方形。例如，如图4C所示，在同一第一连接结构组20a的相邻两个连接结构2中，其中一个连接结构2中的第一螺纹孔22a和第三螺纹孔22c与另一个连接结构2中的第一螺纹孔22a和第三螺纹孔22c相邻，四者在第一调平面221上的正投影的中心连线构成第一正方形(如图4C中这四个螺纹孔的中心连线构成的粗线框所示)。
对于四个相邻的承载箱体1，与四者的毗邻设置的侧边相邻的四个螺纹孔22在第一调平面221上的正投影的中心连线构成第一正方形。例如，如图4C所示，在同一第一连接结构组20b的相邻四个连接结构2中，四个第一螺纹孔22a相邻，四者在第一调平面221上的正投影的中心连线构成第一正方形(如图4C中这四个第一螺纹孔22a的中心连线构成的粗线框所示)。
在本实施例中，连接板31为使相分离且独立的多个结构件，连接为一个整体的结构件。如图5所示，该连接板31的第二调平面311上设置有四个通孔313，如图6A和图6B所示，四个通孔313在第二调平面311上的正投影的中心连线构成第二正方形，该第二正方形能够与上述第一正方形重合。紧固件32包括四个紧固螺钉321，四个紧固螺钉321分别穿过四个通孔313，并分别与相邻的至少两个承载箱体1之间的相应的四个螺纹孔22螺纹配合。
例如，对于任意两个相邻的承载箱体1，与二者的毗邻设置的侧边相邻的四个螺纹孔22在第一调平面221上的正投影的中心连线构成第一正方形，在这种情况下，当连接板31处于如图6A所示的位置处时， 四个通孔313在第二调平面311上的正投影的中心连线构成的第二正方形与上述第一正方形重合，从而实现任意两个相邻的承载箱体1之间的组装和水平度的调整，同时如图6A所示，上述连接板31位于承载箱体1的侧边内侧，从而在安装显示模组之后，可以保证连接板31被隐藏在显示模组之后，而不会自箱体的边框外侧暴露出来，不会影响美观性。
在本实施例中，可选的，如图5所示，连接板31的背离上述第二调平面311的表面312上设置有四个凹部314，四个通孔313的一端分别位于四个凹部314的底面上，紧固螺钉321的螺钉头位于该凹部314中。这样，可以避免紧固螺钉321的螺钉头凸出于连接板31的第二表面312，从而可以保证紧固螺钉321不会对显示模组的安装产生影响。
在一些实施例中，可选的，通孔313为光孔。当然，该通孔313也可以为螺纹孔，用以与紧固螺钉321的螺柱螺纹连接。
在一些实施例中，可选的，螺纹孔22的直径小于等于通孔313的直径。这样，可以便于紧固螺钉321穿过通孔313。
在一些实施例中，可选的，通孔313与螺纹孔22的直径的差值范围为大于等于1mm，且小于等于2mm。
在一些实施例中，可选的，通孔313的直径的范围为大于等于5mm，且小于等于10mm；在上述第二正方形的边长方向上的相邻两个通孔313之间的中心距的范围为大于等于10mm，且小于等于30mm。
在一些实施例中，可选的，连接板31采用诸如压铸铝或者铝镁合金等的金属材质；或者，为了适应一些不能使用金属材质的特殊情况，也可以采用诸如PC等的塑料材质。
在一些实施例中，可选的，如图4A和图4B所示，在承载箱体1的每个边角处，三个连接柱21中，最靠近边角的连接柱(即，图4B中 的第一连接柱22a)与构成边角的两个侧边(11a，11b)中的至少一者之间，或者与两个侧边(11a，11b)的相接处之间设置有第一加强筋5a；其余的两个连接柱(即，图4B中的第二连接柱22b和第三连接柱22c)与各自相邻的侧边之间设置有第二加强筋5b，且在其余的两个连接柱(即，图4B中的第二连接柱22b和第三连接柱22c)之间设置有第三加强筋5c。借助第一加强筋5a、第二加强筋5b和第三加强筋5c，可以提高三个连接柱21的强度，从而可以提高结构稳定性。当然，在实际应用中，还可以采用其他任意结构的加强筋，只要能够提高三个连接柱21的强度即可。
在一些实施例中，可选的，第一加强筋5a、第二加强筋5b和第三加强筋5c的远离背板12的第一表面的端面与第一调平面211相平齐，或者低于第一调平面211，例如比第一调平面211低1-2mm。这样，可以避免加强筋凸出于第一调平面211，从而可以保证加强筋不会对连接板31的安装产生影响。
在一些实施例中，为了保证上述拼装件3在位于承载箱体1的用于安装显示模组的安装面一侧时，不会对显示模组的安装产生影响，同时保证拼装件3被隐藏在显示模组之后，而不会自箱体的边框外侧暴露出来，不会影响美观性，可选的，如图7所示，在侧边11的安装面111上，且位于每个边角处设置有避让凹部112，连接板31位于避让凹部112中，并且，安装面111与紧固螺钉321的螺钉头的端面之间具有第一避让间距G1；避让凹部112的侧面112a和与之相邻的连接板31的侧面之间具有第二避让间距G2；侧边11的外周面113和与之相邻的连接板31的侧面之间具有第三避让间距G3。其中，第一避让间距G1可以避免紧固螺钉321的螺钉头的端面凸出于安装面111，同时可以为显 示模组的背面预留一定的避让空间，从而可以保证上述拼装件3在位于承载箱体1的用于安装显示模组的安装面一侧时，不会对显示模组的安装产生影响。第二避让间距G2有助于顺利地将连接板31安装在连接结构2上。第三避让间距G3可以保证拼装件3被隐藏在显示模组之后，而不会自箱体的边框外侧暴露出来，不会影响美观性。
在一些实施例中，可选的，第一避让间距G1、第二避让间距G2和第三避让间距G3均大于等于3mm，例如在大于等于3mm，且小于等于5mm的范围内。
在一些实施例中，显示面板设置在托架上构成显示模组，在承载箱体1组装完成之后，需要将上述托架安装在承载箱体1的侧边11的安装面111上，托架的背面与安装面111直接接触，在这种情况下，安装面111通常会有加工公差(±0.03mm)，同时承载箱体1通常会有平面度公差(0.10mm左右)，而显示模组通常会有厚度公差(±0.10mm)，这三个公差的累计不能保证拼接后的多个显示模组构成的显示面完全平整。为了解决该问题，可选的，如图4A所示，拼装件3还包括至少一个模组调平结构4，用于调整相邻的显示模组之间的平整度。例如，该模组调平结构4包括模组调平本体和四个调节螺钉42，其中，模组调平本体设置在背板12的第一表面上，该模组调平本体例如包括四个支撑柱41，四个支撑柱41分别位于第一表面的与显示模组的托架(图中未示出)的四个边角处相对应的位置处，并且每个支撑柱41中均设置有定位螺纹孔，即，在第一表面的与显示模组的托架(图中未示出)的四个边角处分别设置有四个定位螺纹孔；四个调节螺钉42一对应地与四个定位螺纹孔螺纹连接，四个调节螺钉42用于通过调节自身与定位螺纹孔的相对位置来调节显示模组之间的平整度。
调节螺钉42例如为机米螺丝，其规格可以为M3-M10，长度可以为5-25mm，材质可以为不锈钢，碳钢等。
作为另一个技术方案，本实施例还提供一种拼接显示装置，包括呈矩阵排列的多个承载箱体和用于将多个承载箱体拼接组装在一起的拼装件，其中，每个承载箱体上安装有显示模组，该拼装件包括本实施例提供的上述拼装件。
本发明实施例提供的承载箱体的拼装件和拼接显示装置的技术方案，拼装件位于承载箱体的朝向显示模组的第一表面所在一侧，并被设置为能够调整连接结构组中的连接结构对应的侧边上的安装面之间的平整度。通过使拼装件位于承载箱体的朝向显示模组的第一表面所在一侧，可以适用于箱体背面没有足够的安装空间的场景，提高安装便捷性。
可以解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
