具体实施方式
参照图 1和图 2所示，本发明提供了一种背光模组的拼接背板 100，装配于背光模组 200 的背面， 所述拼接背板 100包括装配部 10和支撑部 12， 所述装配部 10的水平高度平齐或 低于支撑部 12的水平高度，通过各装配部 10相互叠加将若干个拼接背板 100组合装配在一 起。
所述拼接背板 100作为大尺寸背光模组 200的支撑机构， 装设于背光模组 200的背面， 其由若干组拼接式背板 1相互叠合拼接而成，通过多组拼接式背板 1的延伸来支撑整个背光 模组 200， 这样， 可不必成型大尺寸的背板 1来进行背光模组的支撑， 分块成型的背板尺寸 不需太大， 成型简易， 组合支撑更为稳固， 受力均匀， 不易变形。
参照图 2和图 3所示，将两两相邻背板 1相互叠合的部分设为装配部 10， 非装配部为支 撑部 12，在所述背板 1的装配部 10与支撑部 12之间成型有台阶面 14，所述台阶面 14呈直 角。所述装配部 10的水平高度低于支撑部 12的水平高度， 即相邻背板中其中一个背板的台 阶面大于另一背板的台阶面。 设相邻叠合的两背板为第一背板 la和第二背板 lb， 第一背板 la的第一装配部 101低于第一支撑部 121， 在第一背板 la中， 第一装配部 101和第一支撑 部 121之间形成第一台阶面 141 ;第二背板 lb的第二装配部 102低于第二支撑部 122，在第 二背板 lb中， 第二装配部 102和第二支撑部 122之间形成第二台阶面 142。 当第一背板 la 和第二背板 lb相互叠合时，所述第一背板 la的第一装配部 101与第一支撑部 121的高度差 大于第二背板 lb的第二装配部 102和第二支撑部 122的高度差， 即第一台阶面 141的高度 差大于第二台阶面 142的高度差， 使得两背板相互叠合时， 第二背板 lb叠加在第一背板 la 的第一台阶面 141上， 这时， 第一装配部 101和第二装配部 102对齐叠合， 由此将第一背板 la和第二背板 lb组合在一起， 且由于台阶面的设置， 使得装配部不会造成拼接背板的整体 凸起， 保证了整个拼接背板 1的平整。
优选地， 所述相邻背板的装配部 10和支撑部 12之间的台阶面 14高度差相差一倍， 使 得组装后的拼接背板厚度较小。 所述台阶面倾斜角为 90° ~150° 。
为了将两个背板更好地固定在一起， 当将相邻背板叠合在一起后， 需要通过固定件 300 从其侧面套入， 以将两装配部装配在一起。 所述固定件 300优选为螺钉， 其两端端部 30向 内延伸，通过一内部端部 30扣压于所述第二装配部 102之上，所述内侧端部 30的水平高度 低于或平齐于支撑部的水平高度， 由此将两个装配部扣合固定在一起。通过这种结构的固定 件进行装配， 拆装方便， 无需破坏背板的结构。
为了使得整体拼接背板更为稳固，所述背板 1上凸设若干条加强棱 132，所述加强棱 132 交错设置构成框体， 以增强背板的强度。
参照图 4-图 6所示， 为了更进一步增强拼接背板的强度， 在所述拼接背板后增设有水平 补强支架 400， 增加背板在水平方向的强度， 所述水平补强支架 400与拼接背板的长轴相水 平。所述水平补强支架 400上设有若干个卡槽 402，通过所述卡槽 402与背板 1的加强棱 132 相卡合， 以将水平补强支架 400装配于背板 1之后背。 各卡槽 402相互平行， 呈十字形， 根 据加强棱 132的分布间距而对应设置。 若干条水平补强支架 400架设于背板的背面中部。
参照图 1所示， 因背光模组的拼接背板整体较大， 如在同侧叠合， 会造成重心偏移， 为 了使得拼接背板整体平衡稳定，将所述一个拼接背板与另一个拼接背板相叠合， 且两者相互 叠合的装配部相错， 使得拼接背板的上下部分相平衡， 避免因重心偏移而造成失衡。
为了进一步固定整个拼接背板， 在所述拼接背板后增设有垂直补强支架 500， 增加背板 在垂直方向的强度，所述垂直补强支架 500和水平补强支架 400相互交错相叠， 组成框体结 构。 在本实施例中， 垂直补强支架 500和水平补强支架 400对称地装配于拼接背板的背面， 其中，垂直补强支架 500装配于水平补强支架 400的底部，所述垂直补强支架 500上设有若 干个卡槽 502， 通过所述卡槽 502与背板 1的加强棱 132相卡合， 以将垂直补强支架 500装 配于背板 1之后背。在本实施例中， 所述垂直补强支架 500设为 6条， 通过交错相叠的水平 补强支架 400和垂直补强支架 500进一步加强拼接背板的整体强度。
组装时， 首先将待组装的两拼接背板 1相互叠合， 将两个装配部 10相互叠加， 然后， 用固定件 300在装配部的侧面将两者锁靠在一起；接着，在背板 1的背部装配上若干条水平 补强支架 400，增加背板水平方向的强度，并在水平补强支架 400上装配上垂直补强支架 500， 将所有补强支架连为一体， 再通过螺钉固定于背板上， 以增加背板的整体强度。
