Description

背光模组、 背板及液晶显示装置
【技术领域】
本发明涉及液晶显示领域， 更具体的说， 涉及一种背光模组、 背板及液晶 显示装置。
【背景技术】
现量产中的液晶模组均使用整体式的背板。 一般使用金属冲压或者塑料注 射方式整体成型， 使得产品比较重， 产品的材料成本较高。 大尺寸产品需使用 较大的冲压设备， 成本较高， 对应的模具尺寸很大， 结构复杂， 模具成本也很 高。 如图 1所示为现有的一种背板结构简图， 该背板由整块金属整体沖压形成， 其板面上同时也冲压出用于固定 PCB的凸包 80， 其本身耗材较多， 并且重量较 大， 加工过程也繁瑣。 随着市场竟争的日益激烈， 有效的降低设计成本变得越 来越重要， 于是节省材料成本和简化组装工艺成为各设计者研究的重要方向， 于是在原有的整体背板设计上发展处了镂空或是拼接背板的设计， 在一定程度 上降低了成本， 但是拼接或镂空背板强度下降， 进而使得原本在背板上固定的 PCB板变的不易。
凸包， 是设置于背板上用于固定 PCB板等组件的结构， 凸包一般凸出于背 板板面 , PCB板通过螺钉或其他锁附件固定在凸包上， 进而避免 PCB与背板板 面直接接触造成短路。 如图 1所示的现有背板， 该背板上的凸包 80在背板制作 时一体冲压成型于背板之上， 这样背板上的凸包 80的位置是固定的， 难以适应 不同尺寸的 PCB板； 同时对于不同尺寸的 PCB , 以及不同组件数量需求的背光 模组， 需要重新开模制作相应的背板， 针对不同尺寸的 PCB板， 需要开模制作 新的背板， 因此其通用性不好， 并且生产成本在这种情况下会较高。
【发明内容】
本发明所要解决的技术问题是提供一种节约材料、 通用性好的背光模组、 背板及液晶显示装置。
本发明的目的是通过以下技术方案来实现的： 一种背光模组， 包括背板、
PCB板以及用于将 PCB板固定到背板上的锁附件， 所述背板包括由多个支架组 成框架， 及设置在所述支架上的架桥， 所述支架或架桥上设置有滑槽， 所述锁 附件通过其底部的固定结构安装到所述滑槽上。
优选的， 所述滑槽上设置有用于固定 PCB的锁附件， 所述锁附件可以根据 PCB的尺寸设置在滑槽上的相应位置。 通过对 PCB尺寸的确定， 将锁附件设置 在滑槽上的相应位置， 从而可以用一种规格的背板安装不同尺寸的 PCB。
优选的， 所述锁附件为凸包， 所述凸包的底部设置有将其本身安装到所述 滑槽上的固定结构。 凸包具有较好的锁附 PCB的效果， 其可以避免 PCB的电路 短路。
优选的， 所述固定结构为凸包底部设置的螺纹孔。 凸包可以通过螺釘安装 到背板上， 安装方便， 并且可拆卸。
优选的， 所述螺纹孔贯穿凸包。 这样可以仅用一颗螺釘就能实现 PCB、 凸 包以及背板三个组件的相互固定， 螺钉穿过 PCB、 凸包以及背板， 并通过螺母 锁紧， 使三个组件固定。
优选的， 所述固定结构为一体设置在凸包底部的铆釘。 铆接的方式比较筒 单， 同时可以使用机械完成， 方便快捷， 可靠性高。
优选的，所述锁附件为独立蘑菇头。蘑菇头锁附 PCB的方式较为方便快捷。 优选的， 所述锁附件通过螺钉安装到背板上， 所述锁附件可以在滑槽上移 动。 在进行 PCB的安装之前， 可以事先将锁附件安装到背板上， 但是并不进行 锁紧， 使得锁附件可以在滑槽上移动， 这样， 在对各种尺寸的 PCB进行锁附时， 将锁附件移动到相应尺寸的位置， 锁附 PCB后在将锁附件锁紧在背板上， 从而 不需要事先量测位置， 使得安装的过程更为快捷。
优选的， 所述锁附件通过螺钉或铆钉安装到背板上并锁紧， 所述锁附件固 定在所述滑槽上。 这种方式安装精度高。 一种背板， 所述背板包括由多个支架组成框架， 及设置在所述支架上的架 桥， 所述支架或架桥上设置有用于安装锁附件的滑槽。
一种液晶显示装置， 其包括了如上任一所述的背光模组。
本发明由于将背板由多个支架组成框架结构， 在框架上设置用于安装 PCB 等组件的架桥， 支架以及架桥都可以使用通用的成型件组合而成， 制造成本较 低， 并且节约了大量的材料； 同时， 通过在架桥上设置滑槽用以设置凸包， 凸 包可以在滑槽上的任意位置固定， 从而可以根据 PCB尺寸， 将凸包设置在滑槽 上的相应位置， 以使背板可以适应于具有不同 PCB板尺寸或者不同数量的组件 的背光模组或液晶显示装置。

【具体实施方式】
本发明实施例提供一种液晶显示装置， 包括液晶面板和背光模组， 所述背 光模组底部设有背板。 背板包括由多根支架组成的框架， 框架上设有多个架桥， 架桥可以用于固定 PCB和其它背光模组的组件，所述支架或架桥上设置有滑槽， 凸包等用于锁附 PCB的锁附件通过其底部的固定结构安装到所述滑槽上。
针对此方案， 本发明通过以下优选的实施例进一步说明：
如图 2所示本实施例的框架式背板， 背板通过多个支架 110组合成主框架 100, 再配合相应的架桥 120组合固定在支架上， 所述支架包括首尾相连的上 支架 111、 下支架 113、 左支架 114、 右支架 112， 组成整个背板的大框架， 大框 架里面还设有两个中心支架 115, 中心支架 115的两端分别固定在上、 下两个支 架上面。 各个支架上以及两个支架之间设有多个架桥， 架桥 120 上设置有滑槽 121 , 支架以及架桥上相应的设置有固定 PCB板等组件所需要的凸包 800， 在本 实施例中， 凸包 800为作为单独零件存在的凸包。 如图 2所示， 框架式背板的 主框架 100上设置有多个架桥 120, 架桥 120上设置有滑槽 121 (如图 3所示为 一个架桥上设置凸包 800的情况），凸包 800作为单独存在的零件安装在滑槽 121 内。 可以根据 PCB的尺寸需要而进行位置的调整， 其调整范围在滑槽 121内， 从而可以实现对该种尺寸的 PCB的锁附， 这样， 此一种类型的背板可以通用于 多种背光模组。
为了安装上的方便， 可以事先将凸包通过螺钉安装到所述滑槽上， 但并不 将螺釘锁紧， 使凸包可以在滑槽上滑动， 针对 PCB的尺寸将凸包滑动到相应的 位置， 锁附 PCB后再将螺钉进行锁紧。 也可以针对 PCB的尺寸， 直接通过螺钉 或铆釘固定凸包， 再锁附 PCB, 以减少工序。
在本实施例中， 滑槽同样可以设置在支架上， 进而提供更多的凸包安装位 置， 满足一些组件较多的背光模组。
当然， 除了使用凸包将 PCB锁附到背板上外， 也可以使用其它的类似锁附 件， 如蘑菇头等。 将蘑菇头制作成单体存在的零件， 与凸包一样可以安装在滑 槽内， 同样可以达到针对不同 PCB尺寸的锁附。
如图 4及图 6所示为本实施例作为独立零件存在的凸包 800,此类凸包并不 在背板生产时成形在背板上， 而是在需要使用凸包的时候， 在背板 1 的相应位 置上将凸包 800安装上去， 以达到灵活运用凸包 800来定位各种尺寸的 PCB等 组件。
如图 4所示， 凸包 800具有一用于安装固定 PCB板等组件的螺纹孔 810, 该螺纹孔 810—直贯通该独立凸包 800,以使独立凸包 800可以通过螺钉 811从 下方固定到背板 1上， 同时又可以在上方固定 PCB板， 相应的， 背板 1上应当 设置有与所述凸包 800的螺纹孔 810大小相当的凸包安装孔即滑槽， 以使凸包 800能够固定到背板 1上。 同样的， 也可以仅使用一个螺钉配合螺母实现 PCB、 凸包以及背板之间的固定， 如图 5所示， 由于螺纹孔贯通了整个凸包 800, 进而 可以通过一个螺釘 811配合螺母 812直接将 PCB300锁附到背板 1上。
为了使安装方便， 如图 6所示凸包的底部可以设置成铆钉类似的结构， 即 将铆釘与凸包一体成型， 凸包 800的下端部分与背板 1的连接是铆接形式， 即 凸包 800通过铆钉 820铆接到背板 1上。 铆接的方式相对于螺钉连接的方式， 其比较快捷， 并可通过机器完成， 提高生产的效率。 如图 7所示， 凸包 800通 过铆钉 820固定到背板 1上， 然后 PCB300通过螺钉 811固定到凸包上， 完成对 PCB300的锁附。
为了节约材料， 以及加工方便， 凸包可以由板件直接沖压形成， 如图 8 所 示， 凸包 800 内部为镂空结构， 其整体由一板件材料制作而成， 既节约材料， 又方便制作。
当然， 本实施例中所述的独立凸包 800 的形状并不限于图中所示的锥形截 面形状， 相对于其它形状如方形也能达到相应的用途。
在本实施例中， 才艮据背光模组中 PCB的尺寸， 再在相应位置上设置相应的 凸包； 同时， 根据不同数量的 PCB板组件， 设置相应的凸包数量。
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。
