实施例一
本实施例提供了一种箱体、显示模组和显示装置。其中，箱体参与构成显示模组，多个显示模组共同拼接为一个显示装置。因此，为了能够更清楚的说明本实施例中的箱体的技术特征以及有益效果，本具体实施例方式中，以采用了上述箱体的显示模组和显示装置为例来进行说明。
请参看图1，本实施例提供的显示装置，包括多个显示模组300，多个所述显示模组300的周侧相互拼接，组成一显示面。
请结合参看图2和图3，其中，显示模组300包括箱体100和安装在箱体100的前安装面110的显示板模块200，以及安装在箱体100的后安装面的电源及控制模块（未示出）。其中，显示板模块200包括呈矩阵状排列的多个RBG光源；电源及控制模块，则连接外部电源，然后为显示板200供电，以及提供控制信号。本实施例中，以显示装置呈平面状显示为例来进行说明，在其他实施例中，也可以是曲面显示或者斜面显示等等。
请参看图4，本实施例所提供的显示装置，在装配后，可以拆卸位于中间位置的显示模组300，从而具有可以前后维护的效果。其中，如何拆卸位于中间位置的显示模组300，具体在于箱体的结构变化。具体的如下：
所述箱体100包括：用于安装显示板模块200的前安装面110，以及设于所述前安装面110的后侧，并且围绕所述前安装面110设置的周侧面（未标注）。其中，本实施例中箱体100整体呈长方体状，当然，在其他实施例中，箱体也可以是其他形状，例如圆饼状、沙漏状或者其他形状等等。
所述周侧面沿周向均匀设有一第一区域（未标注）和一第二区域（未标注）。其中，所述第一区域和第二区域可以具有明显的界线，例如第一区域为上侧面和左侧面，第二区域为下侧面和右侧面，从而转角处即为明显的界线。当然，也可以不具有明显的界线，例如第一区域包括部分上下侧面，以及全部左侧面，而第二区域包括身下部分上下侧面，以及全部右侧面。或者，第一区域仅设置于左侧面，而第二区域仅设置于右侧面。
所述第一区域凸设有多个第一连接结构160；请结合参看图5、图6和图7，所述第一连接结构160的后侧面与其他箱体100的第二连接结构170的前侧面配合连接。其中，第一连接结构160全部设置在第一区域内。
所述第二区域凸设有与多个所述第一连接结构160对应的多个第二连接结构170，请结合参看图8和图9，每一所述第二连接结构170的前侧面与对应的所述第一连接结构160的后侧面呈对应设置；所述第二连接结构170的前侧面与其他箱体100的第一连接结构160的后侧面配合连接。其中，第二连接结构170全部设置在第二区域内。并且，与第一连接结构160呈对应设置。本实施例中所说的第二连接结构170的前侧面与第一连接结构160的后侧面呈对应设置，其含义是：上述的前侧面和后侧面呈共面设置，从而实现相互直接连接；或者是对齐设置，通过中间增加垫片等来间接连接。其中，共面是包括严丝合缝的状态，以及具有几十/几百丝米间隙或者误差的正常制造装配状态。
其中，第一连接结构160和第二连接结构170可以是卡扣连接、螺接或者是插销连接等等。从而可以达到可拆卸连接的效果。在装配时，由于第一连接结构160的后侧面作为配合面，因此，第一连接结构160在拆卸时，向后无法移动，而可以向前侧移动。而第二连接结构170的前侧面作为配合面，因此，第二连接结构170在拆卸时，向前无法移动，而可以向后侧移动。进一步的，由于第一连接结构160和第二连接结构170分布于箱体100的第一区域和第二区域。从而可以以第一区域和第二区域之间的中线为轴线而转动，如图4所示。进而可以将位于显示装置中间的箱体100进行旋转然后取出，达到可前后维护的效果。
因此，本实施例所提供的显示装置，通过所述箱体100的周侧面沿周向均匀设置一第一区域和一第二区域。并且所述第一区域凸设有多个第一连接结构160；所述第二区域凸设有与多个所述第一连接结构160对应的多个第二连接结构170。其中，所述第一连接结构160和第二连接结构170的连接配合面相反。从而，能够将位于显示装置中间的箱体100进行旋转然后取出，达到可前后维护的效果。
进一步的，在本实施例中，所述箱体100采用长方体结构。所述周侧面包括上侧面120、下侧面130、左侧面140和右侧面150。
所述第一区域和第二区域呈分布于穿过前安装面110中心的一轴线180的两侧状设置。轴线180穿过前安装面110的中心，从而使得周侧面在轴线180的两边具有相等的面积。进而能够便于箱体100在拆卸时转动，而在转动时减少与其他箱体之间的干涉情况。可以了解的是，轴线180为虚拟的，并非实体存在。
在本实施例中，所述轴线180穿过一对角。请参看图3，该对角为右上角和左下角。从而上侧面120和左侧面140为第一区域，而下侧面130和右侧面150为第二区域。
当然，在其他实施例中，还可以是：
所述轴线180穿过上侧面120和下侧面130，或者，
所述轴线180穿过左侧面140和右侧面150，或者。
例如轴线180穿过上侧面120和下侧面130的中间位置；或者轴线180穿过上侧面120的中间偏右1/2的位置，则轴线180将穿过下侧面130的中间偏左1/2的位置。相应的，轴线的两侧，分别为第一区域和第二区域，再分别在第一区域内设置第一连接结构160和第二连接结构170。
进一步的，在本实施例中，所述第一连接结构160和第二连接结构170包括突出的连接板，以及贯通所述连接板前后侧的安装孔；所述第一连接结构160和第二连接结构170通过螺接固定。
本实施例中，设置第一连接结构160和第二连接结构170呈突出连接板设置，则具有结构简单和便于制造的效果。在本实施例中，第一连接结构160和第二连接结构集成在箱体100上，从而可以具有较高的制造精度。
进一步的，所述连接板的安装孔与显示板模块200伸出箱体100部分的边缘对齐，从而便于在多个箱体100拼接后，相邻的显示板模块200能够实现无缝对接。
具体的，所述第一连接结构160设于上侧面120和左侧面140；所述第二连接结构170设于下侧面130和右侧面150。从而装配工人在需要维护一个显示模组300时，卸掉其固定的螺丝，然后驱动显示模组300，而使其顺时针转动，从而能够前后翻面而便于拆卸和维修。
具体的，所述上侧面120凸设有多个上连接板，具体包括上连接板12、上连接板121、上连接板122、上连接板123和上连接板124。所述上连接板上设有贯通所述上连接板前后侧的安装孔（未标注）；该安装孔用于供螺栓穿过，以螺接固定。
所述左侧面140凸设有多个左连接板，具体包括左连接板141、左连接板142、左连接板143、左连接板144，所述左连接板上设有贯通所述左连接板前后侧的安装孔（未标注）；该安装孔用于供螺栓穿过，以螺接固定。
所述上连接板和左连接板组成所述第一连接结构160。
所述下侧面130凸设有多个下连接板，具体包括下连接板131、下连接板132、下连接板133、下连接板134，所述下连接板上设有贯通所述下连接板前后侧的安装孔；该安装孔用于供螺栓穿过，以螺接固定。
所述右侧面150凸设有多个右连接板151、右连接板152、右连接板153、右连接板154，所述右连接板上设有贯通所述右连接板前后侧的安装孔；该安装孔用于供螺栓穿过，以螺接固定。
所述下连接板和右连接板组成所述第二连接结构170。
本实施例中，通过在箱体100的每一侧面设置多个连接板，从而能够增强与其他箱体100之间的连接强度。
进一步的，在本实施例中，位于同一侧的多个连接板呈前后方向上错位设置。例如：请参看图6，上侧面110上的上连接板121和上连接板124位于一个高度，而上连接板122和上连接板123位于另一高度。再例如：请参看图7，左侧面140上的左连接板141和左连接板143位于一个高度，而左连接板142位于另一高度。
本实施例通过将同一侧的多个连接板，设置为错开式，则一方面，可以避免箱体100在铸造后，其同一侧面上的应力集中的情况；另一方面，可以同一侧面的连接板与其他箱体100的连接板连接时，受力较分散，从而使得箱体100的框架能够更牢固和稳定。
进一步的，本实施例中，一侧的多个连接板分别与背对侧的多个连接板呈前后方向上错位设置。例如：请参看图6，上侧面110上的上连接板121和对应的下侧面的下连接板131呈错位设置。再例如：请参看图7，左侧面140上的左连接板141与对应的右侧面150上的右连接板151呈错位设置。
本实施例中，通过设置背对侧的一对连接板呈错位设置，从而能够便于在两者前后对齐后，通过螺栓连接。并且在连接之后，显示板模块200能够位于同一个平面。
当然，在其他实施例中，背对侧的一对连接板也可以设置在同一平面，或者是不同的平面上，但是还未达到完全错开的程度。然后再通过直接连接的方案连接，或者是其他连接件来实现连接和固定的功能。在直接连接后，可以将将显示屏拼接为曲面或者斜面状；而通过其他连接件来实现连接，则可以将显示屏拼接为平面、曲面或斜面状。
进一步的，请结合参看图6至图9，从前安装面110向后的方向上分为多层；
位于一侧的至少两个连接板设于不同层。
位于一侧的多个连接板的所在层与背对侧的多个连接板的所在层，呈不同层状设置。例如，一侧设置在1层和2层，则另一侧设置在3层和4层；或者，
一侧设置在1层和3层，另一侧设置在2层和4层；再或者，
一侧设置在1层和4层，另一侧设置在2层和3层；再或者，
一侧设置在1层和4层，另一侧设置在2层和5层；3层留空等等。
具体的，本实施例中：
从前安装面110向后的方向上分为四层；位于一侧的连接板设于相间隔的两层，位于背对侧的连接板设于相间隔的另外两层。其中，图中Z轴方向为从前向后的方向。请参看图6，上侧面110上的上连接板121和上连接板124位于第一层，而上连接板122和上连接板123位于第三层，从而多个上连接板实现了呈错开状设置。相应的，与上连接板对应的下连接板中：下连接板131和下连接板134位于第二层，而下连接板132和下连接板133位于第四层，从而既实现了多个下连接板呈错开状设置，还实现了多个下连接板和对应的多个上连接板呈错开设置。
因此，本实施例中，通过设置位于一侧的连接板设于相间隔的两层，而背对侧的连接板设于相间隔的另外两层。从而结构简单精巧的实现一侧的多个连接板呈错位设置，并且背对侧的连接板也呈错位设置。达到一方面使得箱体100的框架牢固稳定，另一方面，便于箱体100在拆卸时可以绕轴线180进行旋转。
实施例二
本实施例提供了一种显示装置。本实施例以上一实施例为基础，对其中的连接板上的安装孔部分进行了改进。为了能够使得描述更清楚和简洁，未做改动的部分，沿用上述实施例中的标号。本实施例，具体如下：
请结合参看图10和图11，所述箱体100还包括用于定位相互连接的箱体的契合定位结构。
所述契合定位结构包括设于第一连接结构160上的第一契合平面和第一契合凸起，以及设于第二连接结构170上的第二契合平面和第二契合凹陷。其中，本实施例的契合定位结构形成于安装孔部分。具体以形成于左连接板141，和对应的右连接板151上的契合定位结构为例来进行说明。
所述左连接板141的安装孔的后侧周缘向后凸出，形成所述第一契合凸起1411，所述第一契合凸起1411的周面呈圆锥周面状设置；所述第一契合平面1412呈围绕所述第一契合凸起1411的圆环状设置。
所述右连接板151的安装孔的前侧周缘径向向外扩张，形成所述第二契合凹陷1511，所述第二契合凹陷1511的周面呈圆锥周面状设置；所述第二契合平面1512呈围绕所述第二契合凹陷1511的圆环状设置。
在装配到位时，所述第一契合平面1412和第二契合平面1512相互贴合，所述第一契合凸起1411和第二契合凹陷1511相互契合，以定位相互连接的两箱体的空间位置。
本实施例中将定位的契合定位结构集成在箱体100上，从而无需另外设计定位机构，降低箱体100的成本。
进一步的，通过对第一契合凸起1411的外周面进行精加工，以及对第二契合凹陷1511的内周面进行精加工。就可以实现整个箱体的定位加工，精度提高的同时也降低了加工成本。
请结合参看图10和12，进一步的，所述第一连接结构160和第二连接结构170上对应的安装孔对齐时，构成形状前后对称的贯通孔，用于供螺接杆件190从前侧面和后侧面无差别插入并连接。例如：左连接板142和右连接板152采用的螺接杆件190由前向后插入螺接。而左连接板143和右连接板153采用的螺接杆件190由后向前插入螺接。
本实施例中，螺接杆件190可从前面或背面，或者前面和背面同时多方向安装，提供了更大的产品设计灵活性和应用范围。其中，螺接杆件190可是松不脱螺钉、其他螺钉、螺栓、拉钉、铆钉等，相应成本较低。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的申请构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
本申请技术方案通过，通过所述箱体的周侧面沿周向均匀设置一第一区域和一第二区域。并且所述第一区域凸设有多个第一连接结构；所述第二区域凸设有与多个所述第一连接结构对应的多个第二连接结构。其中，所述第一连接结构和第二连接结构的连接配合面相反。从而，能够将位于显示装置中间的箱体进行旋转然后取出，达到可前后维护的效果。因此，具有工业实用性。
