Description

一种正反面装配式LED显示模组及拼装式LED显示屏 技术领域
本实用新型涉及LED显示屏技术领域，尤其是一种正反面装配式LED显示模组以及基于此显示模组所形成的拼装式LED显示屏。
背景技术
随着LED显示技术以及城市建设进程的不断发展，户外LED显示屏作为传播媒体的广告新载体得到了越来越多的运用，其不但能够实现动态画面的显示，而且画面内容能够不断地进行更新。
目前，传统的LED显示屏(尤其是面积比较大的显示屏)一般是利用结构件将多个小尺寸的屏体单元拼接而成，为了保证拼接结构的稳定性，对结构件设计了非常复杂的结构，由此也导致施工过程非常缓慢、费时费力、不易拆装及维护等。同时，每个屏体单元的显示部分又是由多块显示模组拼装而成，为保证屏体单元显示的效果以及显示部分的表面平整度，一般是将显示模组放置于屏体单元的箱体后，通过螺丝、铆钉等连接件由显示模组的后侧将显示模组固定于箱体上；如此，当其中一个显示模组出现故障后，需要整个屏体单元或者整个显示屏进行拆卸，才能够对出现故障的显示模组进行拆卸维护或者更换；通常为避免上述问题的发生，人们一般会在显示屏的背面预留足够的维修空间，以便安装人员或者维护人员进入显示屏后面对其进行安装维护，然而，这种方式无疑会占用较大的建筑空间，当LED显示屏的安装场地和环境无法提供这个空间时，依然需要将LED显示屏整体从墙面上拆卸下来进行维护，从而给显示屏的维修保养造成了极大的方便。

具体实施方式
以下结合附图对本实用新型的实施例进行详细说明，但是本实用新型可以由权利要求限定和覆盖的多种不同方式实施。
如图1至图3所示并结合图5所示，本实施例提供的一种正反面装配式LED显示模组，它包括模组主板体1，在模组主板体1上、沿前后方向开设有若干个过孔2，在模组主板体1的背面、与每个过孔2相临近的位置设置有一安装固定块，在安装固定块上、与过孔1相对中的位置套接有一前紧锁螺丝3，同时在安装固定块上还开设有至少一个后置螺孔4。如此，可利用单独配置的工具(如具有与过孔2的孔径相适配的长杆状螺丝刀，螺丝刀的端部的形状与前紧锁螺丝3的螺帽孔位形状相匹配，如十字形、六角形等等)经由过孔2将前紧锁螺丝3锁固于显示屏箱体或者显示屏框架上，以此可实现显示模组的正面装配与拆卸；同时，根据拼装的具体环境或者要求，也可对显示模组进行反面拆装，即：通过螺丝等连接件与后置螺孔4的配合，直接从显示模组的背面将显示模组固定于显示屏箱体或者显示屏框架上；从而增加了显示模组拆装的多样性，使其不受拼装环境的限制，极大地提高了显示模组拆装、维护及更换的便捷性。
为保证显示模组在进行正面装配时，能够快速准确地与显示屏箱体或显示屏框架进行结构装配；本实施例的前紧锁螺丝3包括贯穿于安装固定块分布的主杆部31、形成于主杆部31的前端并与安装固定块的前表面相抵的螺帽 部32以及贯穿于螺帽部32开设并延伸至主杆部31内的多边形锁孔部33(其可采用正六边形，当然并不只限于此形状)，多边形锁孔部33与过孔2相对中，同时，主杆部31的后端部的截面形状设置为多边形(如正六边形等等，但不限于此形状)，在主杆部31的前端部的外壁上形成有外螺纹34。如此，可预先在显示屏箱体或者显示屏框体上开设与前紧锁螺丝3相对位的孔位(孔位的入口形状可与主杆部31的后端部的形状相同)，当对显示模组进行装配时，可将单独配置的工具穿过过孔2，使工具的端头插套于多边形锁孔部33内，而后利用主杆部31的后端部与相对应的孔位的形状关系快速且准确地将主杆部31插套于对应的孔位内，通过对前紧锁螺丝3的旋转操作并利用外螺纹34将前紧锁螺丝3最终锁固在显示屏箱体或者显示屏框体上。
为进一步优化整个显示模组的结构，本实施例的安装固定块包括固定于模组主板体1的背面的横梁板5以及装设于横梁板5的中部并与模组主板体1相分离的纵向板6，前紧锁螺丝3套接于纵向板6上，而后置螺孔4则开设于横梁板5上；如此，通过将前紧锁螺丝3与后置螺孔4的隔离分开设置可有效提高对显示模组的正面拆装及背面拆装的便利性。
由于显示面积较大的显示屏大都由多块显示模组拼装而成，因此，为实现显示模组之间的无缝拼接，保证显示屏的显示效果，本实施例的模组主板体1包括外框11以及由前至后顺序地装设有外框11内的面罩12、LED灯板(图中未标注)和后盖板13，面罩12的其中一个侧壁的后端或其中两个相邻的侧壁的后端形成有第一错位搭台121，面罩12上、与第一错位搭台121所处的侧壁相对称的侧壁的前端形成有第二错位搭台122。如此，相邻的两个显示模组拼装时，可通过在各自的面罩12上所形成的错位搭台构成错位叠置的关系，从而避免在显示模组的正面出现较大的拼装缝隙，并最终实现屏体的无缝拼接。
另外，在模组主板体1的背侧还可根据具体情况设置具有出线端口的电气连接座A和电气连接座B，以在一个显示模组单独使用或者多个显示模组拼装时提供接线空间。
基于上述显示模组，如图4至图10所示同时结合图1至图3，本实施例还提供了一种拼装式LED显示屏，它包括通过若干个拼装结构件拼装为一体的若干个框体(即构成一个大面积的显示屏框体)，在每个框体的正面均装设有至少一块显示模组(即每个框体的正面可由多个显示模组拼装成显示屏的显示部分)，本实施例的显示模组采用上述的一种正反面装配式LED显示屏模组，显示模组经由过孔1并通过前紧锁螺丝3由框体的前侧锁固于框体上或通过套接于后置螺孔4内的第一螺栓连接件(图中未示出)由框体的后侧锁固于框体上。从而整个显示屏的显示模组可根据具体安装环境及要求进行正面拆装或者反面拆装，尤其是采用正面拆装时，对整个显示屏的维护不会受到建筑空间的限制；同时，也可利用装设于相邻的两个框体上的不同显示模组所具有的错位搭台的结构保证显示屏正面不会出现过大的拼装缝隙。
为提高显示屏装配的快捷性，同时保证显示屏拼装后的结构稳固性；本实施例的拼装结构件包括装设于每个框体的右下角处的第一角码7、左下角处的第二角码8、右上角处的第三角码9以及左上角处的第四角码10；本实施例的框体可由四个边框首尾相接构成，且在首尾相接处通过对应的角码进行固定。其中，第一角码7的右侧壁的中部向右延伸后形成有第一叠置台71，第二角码8的底面向左延伸后形成有用于供第一叠置台71叠置放置的第二叠置台81，第三角码9的顶面向右延伸后形成有用于供第二叠置台81叠置放置的第三叠置台91，第四角码10的左侧壁的中部向左延伸后形成有用于供第三叠置台91叠置放置的第四叠置台101；同时，本实施例的拼装结构件还包括若干个贯穿于第一叠置台71、第二叠置台81、第三叠置台91和第四叠置台101分布的第二螺栓连接件a。
如此，当整个显示屏包括至少四个呈“田”字形分布框体时，位于显示屏中心处的拼接位置会呈现第一叠置台71、第二叠置台81、第三叠置台91和第四叠置台101顺序叠置分布的情况，在此处利用第二螺栓连接件a可将四个框体的相应角码进行锁固，而在显示屏的四周的拼接位置则会呈现第一角码7与第三角码9相叠置、第二角码8与第四角码10相叠置、第一叠置台71与第二叠置台81相叠置、第三叠置台91与第四叠置台101相叠置等状态，在这些拼装位置均可利用第二螺栓连接件a作进一步锁合，从而可利用第二螺栓连接件a对相应叠置的角码构成强大的牵制力，保证显示屏拼装后的结构稳固性；当显示屏由若干个呈“一”型分布的框体构成或者由若干个顺序叠置的框体构成时，即可利用上述结构原理(即对应的角码相叠置或者对应的叠置台相叠置)，通过第二螺栓连接件a进行锁固。
为进一步提高显示屏拼装后的结构稳固性，同时增强每个框体本身的结构强度，在第一角码7的左侧还形成有固定于框体的底边框右端侧上的第一固定板72，在第二角码8的右侧还形成有固定于框体的底边框的左端侧上的第二固定板82，在第三角码9的左侧还形成有固定于框体的顶边框的右端侧上的第三固定板92，在第四角码10的右侧还形成有固定于框体的定边框的左端侧的第四固定板102；同时，拼装结构件还包括若干个贯穿于第一固定板72和第三固定板92分布和/或贯穿于第二固定板82和第四固定板102分布的第三螺栓连接件b；以此，在利用每个框体自身的角码来实现框体拼装并保证框体结构稳固性的同时，也可利用第三螺栓连接件b对相互间呈上下叠置分布的两个框体作进一步锁合，以此，可在每个角码上均形成至少一个位于框体外侧的第二螺栓连接件b的锁紧点和一个位于框体内侧的第三螺栓连接件c的锁紧点，从而能够有效地增强显示屏的整体结构的稳固性。
为增强框体拼装的快捷性，提高拼装效率并同时增强显示屏的结构稳固性，在第二叠置台81的上表面上、第四叠置台101的上表面、第三角码9的本体的上表面以及第四角码10的本体的上表面均设置有若干个定位柱c，相 应地，在第一叠置台71上、第三叠置台91上、第一角码7的本体的底面上以及第二角码8的本体的底面上均开设有若干个与定位柱c对位配合的定位孔d。如此，在框体拼装时，可利用定位孔d与定位柱c的对位配合快速地将待对位的角码进行对位摆放，以便通过后续的螺栓连接件进行锁固，与此同时，定位柱c也可间接起到增强相对应的两个角码之间叠置后的结构牢固性。
为能够为诸如电源、系统板等器件提供安装空间，在每个框体的后侧中部均装设有一控制箱(此时可将显示模组的电气连接座A和B置于控制箱内)，本实施例的控制箱包括固定于框体的其中两个对称边框(如顶边框与底边框)之间的底壳e以及固定于框体内并位于底壳e的后侧且与底壳e并行分布的衔接盖板f，在底壳e的两个对称侧壁(如左侧壁和右侧壁)上均设置有一第一卡槽e1，在衔接盖板f的对称侧边上均设置有一与第一卡槽e1并行分布的第二卡槽f1，在衔接盖板f与底壳e的两个对称侧壁所形成的空隙之间装设有一弧形盖板g，在弧形盖板g上、与第一卡槽e1相邻的侧边上设置有一与第一卡槽e1对位卡合的第一卡凸g1、与第二卡槽f1相邻的侧边上设置有一对位插套于第二卡槽f1内的第二卡凸g2。如此，显示模组无论是正面装配还是反面装配，均可直接从控制箱的侧面方向对弧形盖板g进行拆卸，以便对控制箱内的器件进行维护(当显示模组采用正面装配时，只需将显示模组从框体拆卸下来后进行操作即可；基于此，可实现整个显示屏的正反面拆装及维护的性能。
另外，本实施例的控制箱也可设置于框体的侧边处(此时可将显示模组的电气连接座A和B置于控制箱内)，以便于对相邻的显示屏单元的控制部分进行线路等方面的整合，即：框体包括两个相互间呈上下并行分布的横向边框h以及两个截面均呈“L”形的纵向边框k，横向边框h和纵向边框看通过拼装结构件(即相应的角码)围合呈框体结构，在每个纵向边框k上、位于纵向边框k的两个侧壁之间均装设有一弧形盖板g；利用弧形盖板g与纵向边框k共同构成一个类似于控制箱的独立空间，当对控制箱内的器件进行维护 时，也可采用上述原理对弧形盖板g进行拆卸。当然本实施例的两种控制箱的结构可同时存在于同一个框体内，其具体设置形式取决于设计要求以及现场安装要求。
以上所述仅为本实用新型的优选实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
