Description

多功能胶框及背光模组
技术领域
本发明涉及液晶显示领域，特别涉及多功能胶框及背光模组。
背景技术
随着液晶显示市场竞争越来越激烈，各液晶显示产品开发商在设计产品时往往需要考虑如何提高产品的生产效率，提升产品的竞争力。背光模组作为液晶显示器液晶面板的关键组件之一，其结构的改进将为提高液晶显示器的生产效率与产品性能起到至关重要的作用。如图1所示，现有液晶显示产品的背光模组结构一般由：背板，反射片，导光板，光学膜片，发光单元，胶框41，液晶面板42，前框43等结构组成。胶框41的主要功能就是支撑液晶面板42、压光学膜片、有利于整个背光的结构稳定性和防止灰尘进入模组内部等；前框43的主要作用是固定液晶面板42，防止液晶面板42跳脱，同时遮挡液晶面板42的非显示区和漏光现象。现行主要的固定方式就是通过卡勾或螺丝将胶框41固定在后盖上，放置液晶面板42后，盖上前框43压住液晶面板42，同时通过卡勾或螺丝将前框43固定在后盖上。这种固定方式由于需要对前框43和胶框41分别进行两次固定动作，操作复杂，组装效率低，且分散的零部件数量多，定位时容易遗漏，导致产品质量下降。

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
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。
如图2所示，图2为本发明一实施例中多功能胶框的结构示意图，该实施例提出的多功能胶框，包括支撑液晶面板的框体10和与该框体10外边框活动连接的盖体20，盖体20沿框体10外边框翻转，压住液晶面板边缘，并与框体10扣合。
如图3所示，图3a为图2所示多功能胶框的A向剖视图，图3b为图3a所示多功能胶框中盖体展开的结构示意图，图3c为图3a所示多功能胶框中盖体翻转后的结构示意图。该实施例中，盖体20设有卡孔21，框体10设有对应于卡孔21的卡勾11，盖体20与框体10扣合时，卡勾11伸入卡孔21并与该卡孔21卡合。
本实施例中，在框体10上设有第一凹槽12，卡勾11设在第一凹槽12底部；在盖体20上设有对应于第一凹槽12的第二凸槽22，第二凸槽22可伸入第一凹槽12，卡孔21设在第二凸槽22顶部。当盖体20翻转后，其相对于弯折部位的对边压住液晶面板30，第二凸槽22伸入第一凹槽12，通过按压盖体20，使卡勾11***卡孔21并与卡孔21卡合；当因维修或需要更换液晶面板时，只需扳动卡勾11即可将卡勾11从卡孔21中抽出，重新展开盖体20。此外，框体10和盖体20的扣合部位还可以利用螺钉固定，例如在盖体20上设有安装螺钉的通孔，在框体10上设有对应于通孔的螺纹孔，盖体20与框体10扣合时，螺钉穿过通孔并固定于螺纹孔中。本实施例通过简单的卡勾11或螺钉固定盖体20与框体10，不仅可以防止液晶面板脱落，还便于安装与拆卸，同时由于框体10与盖体20一体注塑成型，减少了零部件个数，有利于降低成本。
本实施例中，框体10与盖体20通过塑胶注射一体成型，盖体20与框体10成为一个整体部件，以减少分散零部件个数。盖体20与框体10之间通过弯折部位活动连接，盖体20可沿弯折处多次翻转。当盖体20展开时，将液晶面板放置于框体10上表面的平台上；当盖体20向上翻转时，盖体20相对于框体10内侧的一面压住液晶面板，且盖体20与框体10通过卡扣或螺钉等方式扣合在一起，以固定液晶面板不松动。此外，本实施例中盖体20为方块状，每个盖体20上设有一个用于与框体10扣合的扣合结构，例如用来***卡勾的卡孔，或用来***螺钉的通孔等，盖体20数量为至少两个，分别排列于框体10两相对外边框，以确保压住液晶面板时施力均匀。例如，当盖体20为四个时，可分别分布在框体10相对两侧边框，每一侧边框分别分布两个盖体20，且两两相对；或四个盖体20分别分布在框体10的四个侧边框，每一侧边框分别分布一个盖体20，位置设在侧边框中部。本实施例在框体10上添加盖体20，以盖体20代替传统的前框，且框体10与盖体20一体注塑成型，减少了零部件个数，有利于降低成本；安装时，只需翻转盖体20，并使盖体20与框体10扣合，即可完成安装，组装方便快捷，有利于提高背光模组的装配效率。
如图4所示，图4为本发明另一实施例中多功能胶框的结构示意图，该实施例中盖体20为长条状，框体每条外边框对应的盖体20上设有多个用于与框体10扣合的扣合结构，例如用来***卡勾的卡孔，或用来***螺钉的通孔等。当长条状的盖体20为两个时，分别设在框体10相对两侧边框；当长条状的盖体20为四个时，分别设在框体10的四个侧边框，以确保对压住的液晶面板均匀施力。本实施例由于将多个扣合结构组装在一个盖体20上，安装时只需要翻转一次盖体20，可以使安装更加快捷，有利于提高组装效率。
参照图2、图3和图4，本发明实施例还提及背光模组，包括液晶面板30，还包括多功能胶框，该多功能胶框包括支撑液晶面板30的框体10和与该框体10外边框活动连接的盖体20，盖体20沿框体10外边框翻转，压住液晶面板30边缘，并与框体10扣合。本实施例中的多功能胶框可包括上述图2至图4所示实施例中所有技术方案，其详细结构可参照前述实施例，在此不作赘述。由于采用上述多功能胶框的方案，本发明背光模组相对现有的背光模组而言，省去了传统的前框，安装更加方便，有利于提高背光模组以及相关液晶显示产品的组装效率，且减少了分散零部件数量，有利于降低成本。
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等效流程变换，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。
