图 2是本发明所述背板实施例一的拆分结构示意图;
图 3是图 1中框角构件的结构示意图；
图 4是图 1中框边构件的结构示意图；
图 5是图 1中框角构件与框边构件拼接结构示意图; 图 6是本发明所述背板实施例二的组装结构示意图。
其中： 1、 框架； 11、 框角构件； 12、 框边构件； 13、 凸耳； 14、 凹槽； 2、 底板； 21、 挡板； 22、 框条； 3、 螺钉。
【具体实施方式】
本发明公开一种液晶显示装置， 所述液晶显示装置包括背板， 作为本发明 背板的实施例一， 如图 1至图 5所示， 包括框架 1和底板 2, 所述框架 1为拼接 式， 包括四个框角构件 11和多个等长的框边构件 12。
本实施例中， 所述框架 1四边中每边由一个或多个框边构件 12拼接而成， 长度方向上具体为两个框边构件 12, 宽度方向上为一个框边构件 12, 所述框边 构件 12与框角构件 11、框边构件 12与框边构件 12之间可以通过螺钉螺接或铆 钉铆接， 从而实现相邻两个构件的快速拼接， 框角构件 11可以提高背板框角处 的强度。
本发明背板采用模块化设计， 把背板的框架 1分解成框角构件 11和等长的 框边构件 12多个单元， 并将其设计标准化， 在液晶显示装置新产品开发时， 只 需要从标准化模块单元中选择框角构件 11和不同数量的框边构件 12搭配拼接 使用即可， 构件的通用性非常高， 从而减少了专用模具开发费用以及缩短产品 的开发周期， 而且可以避免单机种开发时大量呆滞料处理不便的问题， 达到降 成本的目的。
如果所述四个框角构件 11为同一规格， 那么只需一种框角构件 11和一种 框边构件 12就可以拼接出多种尺寸的背板， 需要的模具数量会更少， 通过性更 高。
本发明所述框边构件 12与框角构件 11之间可以具有通用的接口结构。 具 体到本实施例中， 所述接口结构为一个构件上设置凸耳 13, 另一构件上对应设 置凹槽 14, 所述凸耳 13被限定在凹槽 14内。 如图 3和图 4所示， 所述框角构 件 11上设置有凹槽 14， 与框角构件 11连接的框边构件 12上对应设置有凸耳 13 , 所述凸耳 13被限定在凹槽 14内， 然后凸耳 13和凹槽 14上开设有通孔， 螺钉 3穿过通孔把框角构件 11和框边构件 12锁紧。 凸耳 13和凹槽 14定位结 构可以防止相拼接的两个构件以螺釘或铆钉为轴心相对旋转， 增加背板结构强 度。
本发明所述框边构件 12之间也可以具有通用的接口结构，本实施例具体接 口结构为在所述相连接的两个框边构件 12上均设置有凸耳 13， 所述凸耳 13与 相邻的框边构件主体相贴合， 并被螺钉或铆钉锁紧， 当然框边构件 12之间也可 以采用上面所述的凸耳和凹槽配合结构。
作为上述实施例的简单变形， 所述框角构件上设置有凸耳， 与框角构件连 接的框边构件上对应设置有凹槽， 所述凸耳被限定在凹槽内， 同样能达到目的。
本实施例中， 所述底板 2由多块同规格的挡板 21拼接而成， 所述挡板 21 通焊接、 镙接或铆接在框架 1上， 对背板的底板 2也采用拆分设计， 然后进行 拼接组装， 是模块化设计思想的进一步深入， 能进一步降低成本和缩短开发周 期。
作为本发明背板的实施例二， 如图 6所示， 所述底板 2由多块框条 22拼接 成栅格结构， 除了具有实施例一中的有益效果外， 还可以节省底板 2材料， 降 低成本。
当然， 本发明所述的背板也可以不采用框角构件， 而是只包括多个等长的 框边构件， 处于框角的两个框边构件采用特别结构垂直拼接固定， 框边上的框 边构件之间采用通用接口进行首尾拼接， 也能实现模块化设计， 并获得相应的 有益效果。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若千简单推演或替 换， 都应当视为属于本发明的保护范围。
