Description

【技术领域】
本发明属于液晶显示领域， 更具体的说， 涉及一种背光模组及液晶显示装 置。
【背景技术】
现有技术中液晶显示装置一般包括液晶显示面板和背光模组， 由于液晶显 示面板不能发光， 所以需要由背光模组提供发光均匀的面光源， 如图 1 所示， 侧光式背光模组的光源一般为 LED灯条 2, 由于 LED灯条 2发热量较高， 所以 需要设置灯条散热件 3以提高散热效率， LED灯条 2的热量通过灯条散热件 3 传递到背板 1上， 再由背板 1散发到周围空气中。
为了使灯条散热件上的热量快速高效地传递到背板上， 一方面灯条散热件 3应采用传热效果好的材料， 比如铝质挤出型材， 另一方面灯条散热件 3与背板 1内侧表面应充分贴合， 以降低灯条散热件 3与背板 1之间的热接触阻抗， 现有 技术中一般在灯条散热件 3上设置第一固定孔 31 , 在背板 1上设置第二固定孔 11 , 采用螺釘 6把灯条散热件 3紧紧地锁附在背板 1上， 当螺釘 6从背板 1内 部安装时， 为了增加螺釘 6的锁附强度， 背板 1一般会在第二固定孔 11处向外 设置翻边 12, 这样会导致背板 1无法满足外观要求， 不能直接共用为液晶显示 装置的后壳； 当螺釘 6从背板 1外部安装时， 只有螺釘 6的头部露在背板 1外 侧， 能够满足外观要求， 当装配时， 需要将背板 1及散热件 3翻转后反向组装， 此时， 散热件 3在背板 1的下面， 由于背板 1尺寸较大， 视觉上无法确定背板 1 与散热件 3的相对位置， 造成组装困难， 效率低下。
【发明内容】
本发明所要解决的技术问题是提供一种背光模组及液晶显示装置， 所述背 光模组的背板能够满足外观要求， 可直接作为液晶显示装置的后壳。 本发明的技术方案为： 一种背光模组， 包括： 灯条散热件和背板， 所述灯 条散热件上设有第一固定孔， 所述背板上设有第二固定孔， 背光模组还包括连 接件和紧固件， 所述连接件固定在背板的第二固定孔处并向背板内侧伸出， 所 述灯条散热件的第一固定孔套设在连接件上， 所述紧固件与连接件配合把灯条 散热件固定在背板上， 所述连接件从背板外侧安装， 所述第二固定孔处向背板 内侧设有翻边， 所述连接件螺接固定在所述翻边上， 所述翻边上还设有内螺纹， 所述连接件为螺栓， 所述紧固件为螺母。
本发明的另一种技术方案为： 一种背光模组， 包括灯条散热件和背板， 所 述灯条散热件上设有第一固定孔， 所述背板上设有第二固定孔， 背光模组还包 括连接件和紧固件， 所述连接件固定在背板的第二固定孔处并向背板内侧伸出， 所述灯条散热件的第一固定孔套设在连接件上， 所述紧固件与连接件配合把灯 条散热件固定在背板上。
优选的， 所述连接件从背板外侧安装。
优选的， 所述第二固定孔处向背板内侧设有翻边， 所述连接件螺接固定在 所述翻边上。 所述翻边可以使连接件更稳固地固定在背板上， 且能较好地保证 连接件的轴线与背板垂直， 而且不影响背板的外观。
优选的， 所述连接件被位于背板内部的螺母固定在第二固定孔处。
优选的， 所述连接件为螺栓， 所述紧固件为螺母。
优选的， 所述连接件为螺栓， 所述螺栓一端还设有内螺纹， 所述紧固件为 螺釘， 与连接件的内螺纹相配合。

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。
