Abstract

本申请提供一种分体式背板及显示装置，分体式背板包括相互连接的上背板和下背板，分体式背板包括用于承载MiniLED灯板的承载面和位于承载面相反一侧的背面，上背板和下背板的背面均设有加强筋，以此加强上背板和下背板的强度和刚度，减少上背板在抬取过程中的形变量，从而减小MiniLED灯板之间碰撞的几率，降低MiniLED灯板发生破碎的风险。

Description

分体式背板及显示装置 技术领域
本申请涉及显示领域，尤其涉及一种分体式背板及显示装置。
 背景技术
现有MiniLED显示装置的背板为分体式结构，如图1所示，图1为现有技术中背板的机构示意图，背板1由上背板11和下背板12组成，上背板11和下背板12的正面贴附有多块分体式的MiniLED玻璃灯板。
 技术问题
分体式背板的下背板12背面设有补强结构，为考虑美观因素，上背板11背面为平坦表面设计。当从分体式背板两个长边的a、b、c、d四个抬取位抬取贴附有MiniLED玻璃灯板的背板1时，挤压应力由上背板11的侧边向中间部分聚集，使得上背板11贴附有MiniLED玻璃灯板的中间部分形变量最大。当从分体式背板的两个短边的e、f、g、h四个抬取为抬取背板1时，挤压应力同样会由上背板11的侧边向中间部分聚集，使得上背板11贴附有MiniLED玻璃灯板的中间部分形变量最大。MiniLED玻璃灯板属于易碎品，背板发生较大的形变时会挤压MiniLED玻璃灯板，使得各MiniLED玻璃灯板之间相互碰撞，增加MiniLED玻璃灯板破碎的风险。故，有必要提供一种分体式背板及显示装置来改善这一缺陷。

 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。在图中，结构相似的单元是用以相同标号表示。
下面结合附图和具体实施例对本申请做进一步的说明：
本申请实施例提供一种分体式背板，下面结合图2进行详细说明。如图2所示，图2为本申请实施例提供的分体式背板2的背面结构示意图，所述分体式背板2包括相互连接的上背板21和下背板22，分体式背板2包括用于承载MiniLED灯板的承载面和位于承载面相反一侧的背面，上背板21的背面设有加强筋23。
具体的，以上背板21为例进行说明。加强筋23包括多条间隔设置的第一加强筋231，第一加强筋231由上背板21远离下背板22的一侧边缘延伸至上背板21靠近下背板22的一侧边缘，并分别与上背板21的上下两侧边缘相交。当从图1所示的a、b、c、d四个抬取位抬取贴附有MiniLED灯板的背板2时，多条沿竖直方向延伸的第一加强筋231可以防止挤压应力由上背板21远离下背板22一侧的边缘向上背板21贴附有MiniLED灯板的中间部分集中，以此在分体式背板厚度不便的情况下，有效提升上背板21整体的强度和刚性，减少上背板21在抬取过程中或者受到外力的作用下贴附有MiniLED灯板的中间部分的形变量，从而减小MiniLED灯板之间碰撞的几率，降低MiniLED灯板发生破碎的风险。
进一步的，上背板21中多条所述第一加强筋231之间相互平行设置，并且相邻两条第一加强筋231之间的距离沿垂直于第一加强筋231的方向由上背板21的左右两侧向中间渐次递减，从而使得上背板231位于中间部分的第一加强筋231的密度高于位于两侧第一加强筋231的密度，以提高上背板21位于中间部分的强度和刚性，减小上背板231中间部分形变量。
当然，在一些实施例中，上背板21中的多条相互平行设置的第一加强筋231之间也可以采用等距设置，即任意相邻两条第一加强筋231之间的距离相等，只要满足相邻两条加强筋之间的距离大于或等于加强筋壁厚的两倍即可。在另一些实施例中，上背板21中的多条第一加强筋21相互之间也可以采用不平行设置，由上背板21的形变集中处向上背板21的各个侧边延伸并与侧边相交，具体第一加强筋231的设置方式可以根据实际需求进行设定，此处不做限制。
在本申请实施例中，下背板22上同样设有加强筋，下背板22上加强筋的设置方式与上背板21的加强筋23的设置方式相同，此处不再赘述。当然，在一些实施例中，下背板22上同样可以采用现有技术中其他加强筋的设置方式或者补强结构，均可以实现对于下背板22刚性和强度的保证，此处不做限制。
在本申请实施例中，上背板21靠近下背板22的一侧设有间隔排布的多个卡扣，下背板22靠近上背板21的一侧设有多个与所述卡扣对应的卡槽，上背板21与下背板22通过卡扣和卡槽的方式固定连接。当然，在一些实施例中，上背板21和下背板22还可以通过螺栓和螺帽固定连接或者通过黏胶粘接等方式固定连接，此处不做限制。
在本申请实施例中，上背板21与设置于其背面的加强筋23为一体成型的结构。可选的，一体式背板2的材料可以为SECC或者SGCC等金属材料，同样也可以为ABS、PP或者PET等高分子聚合物材料，具体可以根据实际需求进行选择，此处不做限制。
本申请实施例还提供一种分体式背板，如图3所示，图3为本申请实施例提供的分体式背板3的结构示意图，其结构与上述实施例所提供的分体式背板2的结构大致相同，包括相互连接的上背板31和下背板32，上背板31的背面设有加强筋33，加强筋33包括多条由上背板31远离下背板一侧边缘延伸至上背板31靠近下背板一侧边缘的第一加强筋331和两条间隔设置的第二加强筋332，第二加强筋332分别位于上背板31远离下背板的一侧边缘和上背板31靠近下背板一侧的边缘，两条所述加强筋332分别连接第一加强筋331的两端，两条第一加强筋331和多条第二加强筋332形成多个封闭的矩形结构。
当从图1所示的a、b、c、d四个抬取位抬取贴附有MiniLED灯板的背板3时，多条竖直方向的第一加强筋331可以防止挤压应力由上背板31远离下背板32一侧边缘向上背板31贴附有MiniLED灯板的中间部分集中。当从图1所示的e、f、g、h四个抬取位抬取贴附有MiniLED灯板的背板3时，两条横向设置的第二加强筋332则可以防止挤压应力由上背板31左右两侧向中间部分集中，以此在分体式背板厚度不便的情况下，进一步有效提升上背板31整体的强度和刚性，减少上背板31在各个侧边的抬取位置抬取过程中或者受到外力的作用下贴附有MiniLED灯板的中间部分的形变量，从而减小MiniLED灯板之间碰撞的几率，降低MiniLED灯板发生破碎的风险。
进一步的，在本申请实施例中分体式背板3的背面还设有加强铝挤34，加强铝挤34设置于所述上背板31和下背板32的连接处，并分别与上背板31和下背板32固定连接，以此增加分体式背板3整体的刚性和强度，并加固上背板31和下背板32连接的稳定性，防止上背板31和下背板32发生变形和脱落。
具体地，加强铝挤34上设有间隔排布的多个通孔，上背板31和下背板32上同样设有与加强铝挤34上的通孔对应的多个通孔，加强铝挤34通过螺栓和螺帽分别与上背板31和下背板32固定连接。
在本申请实施例中，下背板22上同样设有加强筋，下背板22上加强筋的设置方式与上背板21的加强筋23的设置方式相同，此处不再赘述。当然，在一些实施例中，下背板22上同样可以采用现有技术中其他加强筋的设置方式或者补强结构，均可以实现对于下背板22刚性和强度的保证，此处不做限制。
本申请实施例还提供一种分体式背板4，如图4所示，图4为本申请实施例提供的分体式背板4的结构示意图。本申请实施例所提供的分体式背板4的结构与上述实施例所体用的分体式背板的结构大致相同，图4中仅展示出上背板41的部分。本申请实施例所体用的分体式背板4包括上背板41和下背板，上背板41背面设有加强筋42，加强筋42包括多条由上背板41远离下背板4一侧边缘延伸至上背板41靠近下背板一侧边缘的第一加强筋421和两条间隔设置的第二加强筋422，两条所述第二加强筋422沿垂直于第一加强筋421的方向延伸，并且与多条第一加强筋421交叉连接，以形成交叉网格状结构的加强筋。
当从图1所示的a、b、c、d四个抬取位抬取贴附有MiniLED灯板的背板4时，多条竖直方向的第一加强筋421可以防止挤压应力由上背板41远离下背板一侧边缘向上背板41贴附有MiniLED灯板的中间部分集中。当从图1所示的e、f、g、h四个抬取位抬取贴附有MiniLED灯板的背板4时，两条横向设置的第二加强筋422则可以防止挤压应力由上背板41左右两侧向中间部分集中，以此在分体式背板厚度不便的情况下，进一步有效提升上背板41整体的强度和刚性，减少上背板41在各个侧边的抬取位置抬取过程中或者受到外力的作用下贴附有MiniLED灯板的中间部分的形变量，从而减小MiniLED灯板之间碰撞的几率，降低MiniLED灯板发生破碎的风险。
本申请实施例的有益效果：本申请实施例通过在上背板和下背板设计加强筋，以此加强上背板和下背板的强度和刚度，减少上背板在抬取过程中的形变量，从而减小MiniLED灯板之间碰撞的几率，降低MiniLED灯板发生破碎的风险。
本申请实施例还提供一种显示装置，如图5所示，图5为本申请实施例提供的显示装置的结构示意图，显示装置5包括显示面板51、MiniLED光源52以及分体式背板53。显示面板51为现有技术中的液晶显示面板，此处不再赘述。MiniLED光源52设置于分体式背板53上，MiniLED光源52包括多个MiniLED灯板521，每一所述MiniLED灯板521上设有阵列排布的多个MiniLED，多个所述MiniLED灯板521阵列排布于所述分体式背板53的承载面上。本申请实施例所通过的分体式背板53为上述实施例所提供的分体式背板，其应用于本申请实施例所提供的MiniLED显示装置中同样能够实现与上述实施例相同的技术效果，此处不再赘述。
综上所述，虽然本申请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申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为基准。
