Description

一种前框及背 组
【技术领域】
本发明涉及液晶显示领域， 更具体的说， 涉及一种前框以及使用该前框的 背光模组。
【背景技术】
背光模组为液晶显示装置的关键零组件之一。 功能在于供应充足的亮度与 分布均匀的光源， 使液晶显示装置能正常显示影像。
前框在背光模组及液晶显示装置中起外观及支撑件的作用， 以图 1 所示为 例， 液晶背光模组的结构一般包括： 前框 1、 导光板 3、 光源 4、 胶框 5、 背板 6 以及 PCB板 7等部件， 液晶面板 2则设置在背光模组之上， 而前框 1设置在背 光模组的最外侧， 并且对背光模组内的组件进行环围式的包裹整合。 中国实用 新型专利 CN2725935Y液晶荧幕前面壳组件公开了一种前框的结构， 如图 2所 示， 该前框 1为镂空的方形板件结构， 其四周设置有环围的侧壁 11 , 前框 1所 用材料可以是钢板、 可以是铝板、 也可以是塑料或橡胶等。 从成本制作上来看， 钢板、 铝板等金属件已不适于现有前框 1的制造， 对于前框 1的侧壁 11 , 往往 需要增加几步加工工序来实现， 从而提高了加工的成本。
【发明内容】
本发明所要解决的技术问题是提供一种结构强度高且节约材料成本的前框 以及使用该前框的背光模组。
本发明的目的是通过以下技术方案来实现的： 一种前框， 所述前框还包括 至少一层与之层叠设置的层叠板。
优选的， 所述层叠板为前框的周边结构翻折后形成， 所述周边结构为前框 的侧壁或无侧壁的平板边。 通过翻折可以很容易的形成曾叠板。 为了降低成本， 有的前框仅设置了一个或几个侧壁， 其它周边均是平板边， 所以层叠板可以设 置在侧壁以及平板边上。 2
优选的， 所述前框仅设有一层层叠板。 仅设置一层层叠板， 即可达到强度 要求， 又不会过多的增加前框的占用空间。
优选的， 所述前框四周设置有侧壁， 所述层叠板设置在所述侧壁上。 通过 对侧壁增加层叠板以提高前框的强度， 从而可以减小前框的整体厚度， 节约材 料制作成本。
优选的， 所述前框上包括至少一个无侧壁的平板边， 所述层叠板设置在所 述至少一个平板边上。 一般为了节约材料成本和筒化生产工艺， 会将前框的一 个或几个侧壁去掉形成平板边， 同时也保留至少一个侧壁， 然而侧壁本身可以 对前框起到加强作用， 去掉后形成的平板边强度较弱， 所以在平板边上设置层 叠板， 以提高平板边的强度， 从而提高前框的整体强度。
优选的， 所述前框包括一个侧壁以及三个平板边。 一般为了节约材料成本 和筒化生产工艺， 会将前框的三个侧壁去掉形成平板边， 保留一个侧壁， 所以 在平板边上设置层叠板， 以提高三个平板边的强度， 从而提高前框的整体强度。
优选的， 所述层叠板设置在所述前框的内侧面。 前框为外观件， 为保证结 构的优化设计， 层叠板最好设置在前框的内侧面。
优选的， 所述前框为塑胶结构， 所述层叠板为金属板。 一般前框包括多种 材质， 塑胶结构的前框材料成本较为低廉， 因而也被广泛应用， 但是塑胶的结 构强度较低， 通过增加高强度的金属层叠板， 可提高塑胶前框的强度。
优选的， 所述金属板粘接在所述塑胶结构的前框上。 粘接方式优于其它如 螺釘、 铆釘， 可以避免在前框上钻孔或其它结构设置等， 避免造成层叠板的结 构强度降低。
本发明一种背光模组的目的是通过以下技术方案来实现的： 一种背光模组， 包括胶框， 及固定在胶框上的前框， 包括了如上所述的前框。
优选的， 所述前框上至少有一个无侧壁的平板边， 所述平板边上设置有层 叠板， 所述胶框与层叠板抵接。 胶框上对应于层叠板的位置， 进行避让的切薄 设计以使得胶框不至于顶到层叠板， 而使得层叠板的设置不会造成模组厚度的 增力口。
本发明由于在前框上增设了一层与所述前框层叠设置的层叠板， 使得前框 的结构厚度增加， 进而提高前框的整体强度， 在强度得以提高的情况下， 可以 减少前框的板面厚度或是取消前框的一些结构如侧壁， 或者选用更为廉价的结 构材料， 以达到节约材料成本的目的。
【附图说明】

图 2是现有一种前框的结构筒图，
图 3是一种前框结构筒图，
图 4是本发明实施例的前框在液晶背光模组中的结构截面图，
图 5是本发明实施例的前框的截面结构图。
其中： 1、 前框； 2、 液晶面板； 3、 导光板； 4、 光源； 5、 胶框； 6、 背板； 7、 PCB板； 11、 侧壁； 12、 平板边； 13、 层叠板。
【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
前框在液晶显示装置以及背光模组中主要起到外观件的作用， 同时也起到 结构支撑的作用。 一般来说， 前框为镂空的方形结构， 在前框的四周设置有侧 壁， 在设计中， 为了节约材料成本以及筒化加工工艺， 会取消部分侧壁的设计， 如仅保留一个侧壁， 而取消另外三个侧壁使得前框的三个周边形成平板边。 如 图 3所示， 在本发明中， 为了节约材料和筒化生产工艺， 取消前框 1上的三个 侧壁， 仅保留一个侧壁 11 , 另外三边形成平板边 12, 当然， 也可根据需要决定 保留侧壁的个数。 另外， 如图 4所示， 前框 1上另外附加了一层层叠板 13, 层 叠板 13设置在平板边 12的内侧， 并且该层叠板 13由平板边 12翻折形成， 这 样， 平板边 12的厚度是原来的 2倍， 提高了平板边 12处的强度， 在平板边 12 及其上的层叠板 13的支撑作用下， 整个前框 1的强度也得以提高， 从而避免了 由于取消了三个侧壁 11而造成前框 1的强度减弱。 所述层叠板 13的设置， 并 不限于平板边 12的位置处， 对于侧壁 11等， 也是可以行的。 层叠板 13的设置 可以有效提高前框 1 的周边结构 （包括平板边和侧壁） 的厚度， 从而提高周边 结构的强度， 在前框 1 的强度得以提高的情况下， 可以使得削减前框的板厚以 及部分结构如侧壁等， 从而节约了前框的材料成本并筒化了加工工艺。
如图 4及图 5所示为本发明实施例， 前框 1的层叠板 13是通过平板边 12 翻折形成， 但是， 并不限于此种情况， 比如层叠板 13是另外添加设置， 通过螺 釘、 铆釘以及胶水等粘接上去， 对于一些可粘性较好的材料， 以粘接方式最为 方便和可靠， 粘接方式不用对层叠板开孔或其它结构设置， 进而不会造成层叠 板的强度下降。 层叠板 13是向着前框 1的内侧面翻折的， 当然， 也可以向外侧 翻折， 但是， 前框 1 除了支撑作用外也是一个外观件， 向外翻折将影响到工业 设计的需求性。 有的前框使用金属结构， 也有的前框使用塑胶结构， 相比而言， 塑胶结构的前框在材料成本上更为低廉。 因此， 可以通过采用金属结构或强度 高的材料的层叠板添加层叠设置在塑胶结构的前框上， 以提高塑胶结构的整体 强度。
在背光模组中， 胶框 5对应于层叠板 13设置的位置处， 胶框进行必要的切 薄设计， 以使得层叠板 13与胶框 5的抵接处不会造成干涉， 从而避免层叠板 13 的设置不会造成背光模组厚度的增加。
在本发明的实施例中， 因为层叠板的设计， 使得前框的强度得到提高， 所 以前框的材料可以优选用塑胶材料。 当然， 也可以选用塑胶的框体加上金属结 构的层叠板， 以获得更高的结构强度。
另外， 在本发明实施例中， 通过翻折后形成的层叠板 13相对于其它方式固 定上去的层叠板， 其结构强度上要优于其它方式， 因为在弯折处形成的圓形结 构强度也较大， 如圓柱形结构要比长方体状的长柱在结构上强度要大， 并且层 叠板 13与平板边 12相互连接， 进一步增强其可靠性。 这样， 则不需要在平板 边 12及层叠板 13上设置孔以适应螺釘、 铆釘等的设置， 也避免了因为打孔而 造成强度的减弱。
对于现有的前框， 可以不必取消周边的侧壁， 对于此类前框， 也可以在侧 壁上添加层叠板以提高前框的强度， 在前框的强度得以保证的情况下， 可以适 当削减材料降低前框的板厚， 或者使用更为廉价的结构材料， 从而达到节约材 料成本的目的。
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， 还可以做出若干筒单推演或替 换， 都应当视为属于本发明的保护范围。
