【具体实施方式】
本发明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, 其中, 在背板板面上设置有多个用于安装凸包的多个孔。 针对 此方案, 本发明通过以下优选的实施例进一步说明:
在背光模组中, 大部分组件都需要安装固定在背板上, 如 PCB需要通过背 板上的凸包固定到背板上, 而背板可由一整块或多块板件或多块不同材料的板 件加工制作而成。
如图 2所示为一个由一整块板件加工而成的背板, 在其板面上设置有通孔 122,通孔 122的位置可以根据较为常用的 PCB或其他组件的尺寸设置在背板板 面上的相应位置上, 也就是说, 针对每一种规格的 PCB, 背板板面上均设置有 相应的多个通孔 122, 凸包 800可以根据需要选择的固定到多个通孔 122上, 根 据多种规格的 PCB的尺寸, 对应的设置多个位置的孔, 使得一个背板能够适应 多种尺寸的 PCB, 也避免了一些非必要的孔, 使得背板的强度不会被削弱; 或 者, 也可以是一系列等间距的标准孔, 该类标准孔覆盖了多种规格的 PCB所需 要的通孔 122, 以便于加工, 凸包 800可以根据 PCB的尺寸需要选择的固定到 标准孔上。 凸包 800作为一单独存在的零件安装在通孔 122内, 根据不同尺寸 规格的 PCB , 将凸包 800设置在相应位置的通孔 122上, 从而可以实现将该种 尺寸的 PCB锁附到背板上。
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通 孔内, 同样可以达到针对不同 PCB尺寸的锁附。
如图 3及图 5所示为本实施例中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 位置的通孔上将凸包 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 3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可以通过螺釘 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, 如通孔或滑槽, 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釘配合螺母 实现 PCB、 凸包以及背板之间的固定, 如图 4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 5 所示凸包的底部可以设置成铆釘类似的结构, 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通过铆釘 820铆接到背板 1上。 铆接的方式相对于螺釘连接的方式, 其比较快捷, 并可通过机器完成, 提高生产的效率。 如图 6所示, 凸包 800通 过铆釘 820固定到背板 1上, 然后 PCB 300通过螺釘 811固定到凸包上, 完成 对 PCB 300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 7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, 根据背光模组中 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, 还可以做出若干筒单推演或替 换, 都应当视为属于本发明的保护范围。
