Description

组合式背板和其装配方法以及使 其的背光模组 技术领域
本发明涉及一种液晶显示部件， 更具体来说涉及用于液晶显示面板的背板。 本发明还涉及这种组合式背板的装配方法和使用这种组合式背板的背光模组。 背景技术
液晶显示装置具有机身薄、 节省电能等优点而得到了广泛应用。 目前， 市售 液晶显示装置绝大部分为背光型液晶显示器， 其包括液晶显示面板和背光模组。 液晶显示面板的工作原理是在两片平行的玻璃之间设置液晶分子， 通过控制液晶 分子的方向将背光模组的光线折射来产生画面。 由于液晶显示面板本身不发光， 需要借助背光模组来提供光源以正常显示影像。 因此， 背光模组成为液晶显示装 置的重要部件之一。
背光模组通常包括： 背板、 导光板、 背光源和光学膜;†。 在现有技术中， 背 板通常采 整体式结构， 这种结构的体积较大， 导致其生产磨具的体积巨大， 保 养困难， 并 对冲压成型技术亦要求较高。
在现有技术中， 存在图 11结构的背板： 该背板包括本体 22及连接于该本体 22上的第一支架 24„本体 22包括基板 222, 第一支架 24包括第一底板 242及垂 直连接于第一底板 242的第一侧板 244。 第一底板 242远离第一侧板 244的一端 设有第一折弯部 246和连接于第一折弯部 246的水平设置的第一延伸部 248。 第 一延伸部 248搭接在基板 222—端上，并通过铆钉或螺钉固定连接与该基板 222， 即组合背板通过本体 22和支架 24拼接而成。 这种背板虽然分成两部分， 但是仍 然是整体式结构， 当背板的面积较大时， 这会给装配工作带来不便。 因此， 急需 一种便于生产和装配的背板。
针对上述问题， 本发明提出了一种组合式背板， 这种组合式背板通过多个插 板拼接形成， 能方便地生产所需尺寸的背板。 本发明还提出了这种组合式背板的 装配方法和使 ]¾这种组合式背板的背光模组。 根据本发明的第一方面， 提出了一种组合式背板， 包括由多个设置有插槽的 框架条形成的框架， 以及多个设置有弯折壁的插板， 其中弯折壁与插槽形状匹配 地接合， 使得多个插板能安装到框架中以形成组合式背板。
根据本发明的组合式背板采用了插接式装配， 简化了装配操作。 通过安装不 同数量的插板能够制造不同尺寸的背板， 从而不再需要为大尺寸的背板单独制造 模具， 降低了大尺寸背板的生产难度和生产成本。
在一个实施倒中， 框架条的横截面为 L形， 沿其长度方向在其内部贯穿式设 置有插槽。 在一个实施 ^中， 插板包括至少两个第一插板和至少一个位于两个第 一插板之间的第二插板， 其中， 第一插板包括矩形板体和设置在其三个边缘的弯 折壁， 第二插板包括矩形板体和两个设置在其相对边缘的弯折壁。 在一个优选的 实施例中， 弯折壁为 L形， 插槽也为 L形。 L形框架条的横向延伸部分的尺寸小 于或等于 L的弯折壁的横向延伸部分的尺寸。这些结构使得通过将插板的 L形弯 折壁推入到框架条的 L形插槽内即可完成插板的安装， 方便了背板的装配。
在一个实施例中， 插板包括矩形板体和设置在其四个边缘的弯折壁。 这样， 可将插板制诈为相同， 不需要多套模具， 降低了生产成本。 另外， 在装配状态中， 相邻插板的弯折壁会顶靠在一起， 这提高了插板的装配强度。 在一个优选的实施 例中， L形弯折壁的横向延伸部分的尺寸相等。 这样可将框架条制作为相同， 同 样不需要多套模具， 降低了生产成本。
在一个实施例中，插板的 L形弯折壁的竖向延伸部分设置有多个第一固定孔， 在 L形框架条上设置与第一固定孔相对应的第二固定孔。 在安装状态中， 可借助 于固定件将第一固定孔与第二固定孔固定连接在一起， 从而将插板与框架条牢固 地连接在一起。 特别是还可以将相邻的插板通过第一固定孔固定连接在一起， 从 而提高装配强度。 在一个优选的实施例中， 相邻的框架条通过角形连接件相连。
在 ·个实施倒中， 框架条为铝材。 铝材具有较低的密度， 以降低整个组合式 背板的重量。
根据本发明的第二方面， 提供了装配根据上文所述的组合式背板的方法， 包 括， 歩骤一： 将两条框架条平行设置； 步骤二： 在两条框架条之间装入第一个插 板， 并且将插板推到两条框架条的端部； 步骤三： 向第一个插板上以垂直于两条 平行的框架条的方式装入第三框架条； 步骤四： 在第一个插板的后侧继续装入预 定数量的插板； 歩骤五： 在最后一个插板上以垂直于两条平行的框架条的方式装 入第四框架条。
根据本发明的第―三方面， 提供了 ·种背光模组， 其包括根据上文所述的组合 式背板。
在本申请中， ]¾语 "横向"规定为在装配状态中与插板的板体平行的方向， "竖向"规定为与横向垂直的方向。
与现有技术相比，本发明的优点在于：本发明的背板通过多块插板拼接而成， 通过安装不同数量的插板就能够制造不同尺寸的背板， 从而不再需要为大尺寸的 背板单独制造模具， 降低了大尺寸背板的生产难度和生产成本。 在框架条 ή设置 有 L形插槽， 在插板上设置有 L形弯折壁， 这样可方便地将插板与框架条装配在 一起， 简化了装配。

在付图中，相同的部件使用相同的附图标记。附图并未按照实际的比例绘制。 具体实施方式
下面将结合爾图对本发明诈进一步说明。
图 1示意性地显示了根据本发明的组合式背板 10 (以下称之为背板 10) 。 背板 iO包括由四个框架条 i ia、 l ib, :i ic、 i ld组成的框架 11和安装在框架 i i 内的多个插板 12。 为了制造不同尺寸的背板 10， 可将框架条制造成相应的长度 并 拼接相应数量的插板 12。 图 1仅显示了矩形的背板 10, 实际上背板 10还可 以为其他形状。 框架条的数量也不限于四个， 当背板 0 的尺寸较大时， 可以使 ]¾多个框架条。 在一个实施例中， 框架条选择为铝村， 以减小背板 10的重量。
下面以框架条】1 a为飼，来描述框架条〗 la与插板 12之间的连接。在框架条 】1 a内设置插槽， 并且在插板 12的边缘设置与插槽相应的弯折壁。 在一个实施例 中，插板 12设计为包括矩形板体 30和设置在板体 30四个边缘的 L形弯折壁 31， 如图 3所示。 弯折壁 3 包括与板体 30处于同一平面的橫向延伸部分 32和与板 体 30垂直的竖向延伸部分 33 , 图 4显示了将插板 12的弯折壁 31弯折之后的形 式。 框架条 11a构造为其横截面为 L形， 沿框架条 a长度方向在其内部贯穿式 设置有 L形插槽 20 (如图 2所示） 。 插槽 20的尺寸与弯折壁 31的尺寸相匹配， 从而可将插板 12的弯折壁 31插入插槽 20内 （如图 5所示） ， 并能推动插板 12 沿着框架条 l ia运动以进行装配， 这大大简化了背板 )的安装。 为了便于生产， 弯折壁 31 的横向延伸部分 32的尺寸构造为相同， 竖向延伸部分 33的尺寸也构 造为相同。
下面根据图 8-】0来描述根据本发明的背板 10的装配步骤。
首先将框架条 11a和 1 1c平行固定设置， 框架条 11a和 l】c之间的距离与插 板 12的尺寸相匹配。接着将第一块插板】2a两端的弯折壁 31分别插入 11a和 l】c 的插槽 20内并推到框架条 i la和 11c的一个端部， 完成初歩圏定。接着， 根据图 8中的箭头方向将侧部框架条 l ib插入到插板 12的另一个弯折壁 31上以将插板 12完全固定。 然后， ^框架条 11a和 11c的另一端部继续插入预定数量的插板， 如图 9中的箭头所示。 最后， 在最后插入的插板 i2d上在插入框架条 l id, 如图
10中的箭头所示， 完成背板 10的装配。
为了使得背板 10更加牢固， 可选择在插板 12的 L形弯折壁 3】 的竖向延伸 部分 33设置有多个第一固定孔 34，在 L形框架条上设置与第一圏定孔 34相对应 的第二固定孔 35。 在装配结束后， 可借助于固定件 36, 飼如螺栓将插板 12与相 应的框架条固定连接在一起， 并将相邻的插板 12 也固定连接在一起。 另夕卜， 还 可以使用角形连接件 （未示出） 将相邻的框架条固定连接在一起， 从而提高背板 10的强度。
还应理解地是， 插板还可具有两种类型， 第一插板 12'包括在三个弯折壁 3 Γ (如图 6所示） ， 第二插板 12"仅包括两个弯折壁 3 " (如图 7所示） 。 插板 12' 必须与插板 12"配合在一起使用， 其中插板 12'安装在背板 10的两端 （即与侧部 框架条 l ib和 l id相邻） ， 而插板 12"安装在两个插板 12'之间。 容易理解地是, 在这两种插板 12'、 〗2"的弯折壁上也设置有固定孔， 以将插板 12'、 12"与框架 条固定连接， 提高背板 10的强度。
虽然没有在爾图中说明， 但是本发明的背板 10 也能够用于背光模组中， 并 且能提高背光模组的装配效率。
虽然已经参考优选实施例对本发明进行了描述， 但在不脱离本发明的范围的 情况下， 可以对其进行各种改进并且可以用等效物替换其中的部件。 尤其是， 只 要不存在结构冲突， 各个实施例中所提到的各项技术特征均可以任意方式组合起 来。 本发明并不局限于文中公开的特定实施例， 而是包括落入权利要求的范围 Λ 的所有技术方案。
