背光模组为液晶显示器面板的关键零组件之一, 其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。
背光模组一般包括: 背板、 导光板、 光源等组件, 其中, 背板通常采用金 属件成型来制成, 而金属制作的背板一般成本较高, 另外, 为了固定各种电路 板, 通常还需要铆接各种金属铆柱, 进一步增加了生产成本, 再者, 其加工过 程中需要多种设备共同完成, 而设备成本及生产流程都将增加。 塑胶因为其成 型方便以及价格低廉, 慢慢的在背光模组的背板中得以使用, 但是塑胶的强度 相比金属相差较远, 对于塑胶生产的背板, 往往厚度需要加厚, 以达到需要的 强度。

其中: 100、 背板; 110、 加强结构; 120、 扣件; 121、 柱结构; 130、 热源; 140、 冷沖头; 200、 加强筋; 300、 螺釘。
【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。
背板的结构一般为方形的板件结构, 其中, 背板一般采用金属材料制成, 当然, 也有使用塑胶材料的背板以及同时使用金属和塑胶材料的拼接背板。 对 于塑胶背板, 或是较薄的金属背板, 通常会在背板的板面上设置加强结构以及 通过外加加强筋来提高背板的整体强度, 以达到包装背板强度的情况下, 节约 背板的材料成本。
如图 1-5所示为本发明的实施例, 在本实施例中, 背板 100采用塑胶材料, 当然, 背板 100也不限于其它材料如金属或是多种材料拼接。 如图 1所示, 背 板 100为方形的板件结构, 在其板面上形成有加强结构 110, 该加强结构 110在 背板成型时一起形成, 加强结构 110 的形式不限于图中所示的横竖交叉并且等 距的条形结构, 该加强结构 110的作用在于提高背 100的强度并节约背板的材 料使用量。 如图 2及图 3所示, 在背板 100的板面上还设置有加强筋 200, 通过 设置加强筋 200, 以适应尺寸较大的背板 100, 从而不必提高大尺寸的背板 100 的板厚, 以此来节约材料的用量。 加强筋 200通过螺釘 300锁附在背板 100上, 或者, 也可以通过其它方式锁附在背板 100上, 本实施例中, 加强筋 200的锁 附方式优选如图 4-6所示的方式,如图 5所示,加强筋 200通过扣件 120锁附在 背板 100上, 扣件 120与背板 100是整体件。 如图 6所示, 背板 100在成型时在其板面上形成有柱结构 121 , 在将开有孔 的加强筋 200组装到相应的柱结构 121设置的区域上后, 通过热源 130对柱结 构 121进行加热使其软化, 然后利用冷沖头 140对软化后的柱结构 121进行冷 沖压使其定形形成扣件 120, 该扣件 120的形状与螺釘的形状类似, 但并不限于 图中所示的形状, 只要在柱结构 121上形成有反压加强筋 200的倒扣结构便可 以, 此外, 对于金属结构或者其它材料, 可以直接进行沖压而不需要加热, 但 是, 不管是塑胶或是金属或是其它材料, 加热过后的可塑性较好, 并且加热过 后进行的沖压形成的应力较小, 使得倒扣结构更加稳定。 这样, 由于扣件 120 形成于背板 100的板面上, 与背板 100是整体件, 从而扣件 120可以有效的锁 附住加强筋 200。 对于通过螺纹连接的加强筋, 需要在塑胶材质的背板 100上进 行攻丝形成螺纹, 而塑胶材质的背板 100 强度及刚性较差, 采用螺纹连接使得 螺釘容易松动, 则加强筋 200也会产生松动, 这样就造成了加强筋 200加强效 果的减弱, 但是, 通过形成于背板 100上的扣件 120锁附的加强筋 200, 由于与 背板紧紧的连接着, 在不发生塑性变形的情况下不会产生松动, 因此可以保证 加强筋 200紧紧的锁附在背板 100上, 从而保证了加强筋 200的加强作用。 这 样, 通过加强结构 110及加强筋 200的加强作用, 可以适当的减少背板 100的 材料使用量, 从而节约背板 100的生产成本。
在加强筋 200设置的区域,可以取消加强结构 110的设置,并且,加强筋 200 的厚度最好与所述的加强结构 110的高度相等, 以使加强筋 200不至于凸出于 背板 100过多而影响到其它组件的安装。 加强结构 110及加强筋 200的设置大 大提高了背板 100的结构强度, 而且并不会过多的增加背板的厚度。
由于金属背板的材料成本过高, 本发明实施例优先选用塑胶材料, 而且, 塑 胶材料的可塑性好, 成型比较方便, 不需要过多的加工设备, 从而节约了材料 成本和加工成本。 但是, 本发明的构思依然适用于金属结构的背板, 金属结构 的背板也可以通过设置加强筋, 并通过形成与背板上的扣件进行锁附, 保证加 强筋的加强作用, 在此情况下, 可以适当减小金属背板的板厚, 达到节约材料 成本的目的。
另外, 塑胶材料虽然强度低于金属材料, 但是塑胶材料的可塑性较好, 成型 需要的加工成本都要低于金属材料, 并且价格较为便宜, 因此, 在强度达到要 求的情况下, 塑胶材料要优于金属材料。 但是对于薄型化需求较高的液晶显示 装置, 可以优选金属材质的背板, 因为背板在较高的强度下可以做到比塑胶材 料的背板更薄。
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。
