Description

背光模组
技术领域
本发明涉及液晶显示技术领域，尤其涉及一种背光模组。
背景技术
背光模组是液晶显示面板的关键零组件之一，用于供应充足的亮度与分布均匀的光源，使其能正常显示影像。背光模组包括前框、液晶面板、导光板、胶框、背板等等。其中，前框用于固定液晶面板，胶框用于固定导光板及背板。或者额外增加导光板固定板，用于固定导光板。
现有的背光模组设计中，前框的固定方式一般为螺丝固定或者卡勾固定。螺丝固定主要是把前框通过螺丝锁固在背板。如此背板上面需要进行攻牙操作，而且螺丝锁固也需要工时，该方法不利于节约成本。卡勾固定通过设置在前框的侧面的卡勾将前框固定在背板上。虽然其安装简单，但是该卡勾结构容易引起前框正面外翻，从而造成前框与液晶显示面板之间的间隙过大。
发明内容
本发明的主要目的是提供一种背光模组，旨在实现背光模组的前框及胶框的简单安装及拆卸。
本发明提供了一种背光模组，包括前框及胶框，所述前框与所述胶框通过扣接结构连接，该扣接结构包括设置在前框反面上的扣台及设置在胶框正面上、且与所述扣台扣接的扣勾，所述前框的反面设置有与该面垂直连接的第一凸起，所述扣台设置在所述第一凸起的侧壁；所述胶框的正面设置有与该面垂直连接的第二凸起，所述扣勾设置在该第二凸起的侧壁；所述扣台具有第一卡持面及扣勾导入部，扣勾具有第二卡持面及扣台导入部，第二卡持面的面积比第一卡持面的面积大。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
以下将结合附图及实施例，对实现发明目的的技术方案作详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参照图1至图5，图1是本发明背光模组的剖面示意图；图2是图1中设置有扣台的前框一实施例的俯视结构示意图；图3是图2沿A-A线的剖面示意图；图4是图1中设置有扣勾的胶框一实施例的俯视结构示意图；图5是图4沿B-B线的剖面示意图。背光模组包括前框10及胶框20。该前框10与胶框20之间通过扣接结构30连接。该扣接结构30包括两部分，分别为设置在前框10反面上的扣台31和设置在胶框20正面上、且与所述扣台31扣接的扣勾32。该扣台31与扣勾32之间为可拆卸连接，且扣台31与扣勾32均为弹性件。在这里需要说明的是，该前框10的反面是指与胶框20进行装配的一面。胶框20的正面是指与前框10进行装配的一面。
在本发明一种实施方式中，扣台31可以为设置在前框10反面的凹槽，则扣勾32为设置在前框20正面的呈钩状的凸块，该凸块卡抵于凹槽的内端面。在本发明另一种实施方式中，扣台31可以为设置在前框10反面的呈钩状的凸块，则扣勾32为设置在胶框20正面的凹槽，该凸块卡抵于凹槽的内端面。在本发明又一种实施方式中，扣台31可以为设置在前框10反面的呈钩状的凸块，扣勾为设置在前框20正面的呈钩状的凸块，两钩状的凸块互相配合扣接。凡是可以形成可拆卸连接的扣台31及扣勾32结构，能达到固定前框10及胶框20的目的的扣接结构30，均在本发明的专利保护范围内。
本发明通过扣接结构的设置，使得前框10与胶框20形成可拆卸组装，而且不需要借助其他工具。而且扣台31与扣勾32分别设置在前框10的反面及胶框20的正面，解决了现有技术中卡勾结构易引起前框10正面外翻，从而造成前框10与液晶显示面板之间间隙过大的问题。
上述前框10的反面设置有与该面垂直连接的第一凸起41及第三凸起43，所述扣台31设置在所述第一凸起41的侧壁。所述胶框20的正面设置有与该面垂直连接的第二凸起42，该第二凸起42卡持于第一凸起41与第三凸起43之间，所述扣勾32设置在该第二凸起42的侧壁。组装时，胶框20的第二凸起42由第一凸起41及第三凸起43的间隙卡入，由于第一凸起41与第二凸起42上分别设有扣台31及扣勾32，则将使第一凸起41与第三凸起43发生形变。待第一凸起41及第三凸起43的弹性形变恢复，则其扣台31将与扣勾32形成干涉，第三凸起43抵靠第二凸起42，使第一凸起41与第三凸起43形成类似于夹子的结构将第二凸起42夹紧，从而使前框10与胶框20固定。拆卸时，则对第二凸起42施加拉力，挤压第一凸起41及第三凸起43发生形变，从而使得扣台31与扣勾32脱离干涉。
上述第一凸起41、第二凸起42及第三凸起43均为筒状结构，且第三凸起43位于第一凸起41的内侧，所述第二凸起嵌入到所述第一凸起41及第三凸起43之间。
上述扣台31设有扣台导入部311。上述扣勾32设有扣勾导入部321。该扣台导入部314与扣勾导入部324均用于扣台31快速地与扣勾32扣接。
如图6所示，其为图1中A部的局部放大示意图。上述扣台31与第二凸起42形成过隙配合，该扣台31的一部分嵌入到第二凸起42中，扣台31嵌入第二凸起42并抵接第二凸起42的接触面定义为第一卡持面312；扣勾32与第一凸起41形成过隙配合，该扣勾32的一部分嵌入到第一凸起41中，扣勾32嵌入第一凸起41并抵接第一凸起41的接触面定义为第二卡持面322。上述扣台31与扣勾32通过相互扣接使第一凸起41与第二凸起42相互固定，其中第一卡持面312的面积比第二卡持面322的面积小。
参照图7及图8，图7为图1中设置有扣台的前框另一实施例的俯视结构示意图；图8为图1中设置有扣勾的胶框另一实施例的俯视结构示意图。与上述实施例不同的是，前框10的反面设置的第一凸起51与第三凸起53均呈长条状，且并排设置，第一凸起51与第三凸起53均为两个，上述扣台31设置在第一凸起51的内侧壁。胶框20的正面设置的第二凸起52也呈长条结构，且并排设置，第二凸起52也为两个，上述扣勾32设置在第二凸起52的内侧壁。通过两个相对设置的扣台31，使得两扣勾32对应与卡持在扣台31，从而加强了前框10与胶框20之间的固定。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
