Description

液晶显示装置及其背光模组和框架单元
【技术领域】
本发明涉及液晶领域，具体涉及一种液晶显示装置及其背光模组和框架单元。
【背景技术】
现有技术中，液晶显示装置的组装方式很多都是将液晶面板放置在背光模组上，导光板设置于背板组件的支承部上，背光模组的中框抵压导光板以实现导光板的固定。
然而，在液晶显示装置的使用过程中，由于中框抵压导光板，因此会受到导光板施加的一个反作用力，在该反作用力的作用下，中框会发生外翻从而造成液晶显示装置的损坏。
【发明内容】
本发明实施例所要解决的技术问题是提供一种液晶显示装置及其背光模组和框架单元，能够解决液晶显示装置使用过程中中框外翻的问题。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种液晶显示装置，该液晶显示装置包括液晶面板、光源、导光板以及框架单元，。框架单元包括支架和中框。支架设置有相连接的支承部和竖直部，支承部用于承载液晶显示装置的导光板，竖直部远离支承部的一端设置有配合部，配合部靠近导光板的一端设置有配合面，配合面由竖直部靠近导光板的一侧向竖直部远离导光板的一侧倾斜；中框靠近导光板的一端抵压导光板，中框靠近支架的部分设置有倒U型槽，配合部容设于倒U型槽中，配合面与倒U型槽靠近导光板一侧的内表面相抵接。光源设置在述竖直部上，导光板设置在支承部上，中框上设置有承载部，液晶面板设置于承载部上。
其中，配合面为平面或曲面。
其中，支架由铝材制成。
其中，配合部靠近导光板一端的顶部设置有装配角。
其中，配合部远离导光板的一侧设有钩合部，倒U型槽远离导光板的部分设置有钩合槽，钩合部与钩合槽钩合式配合。
其中，配合部远离支承部的一侧与倒U型槽的内表面紧密配合。
其中，支承部和竖直部一体成型。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种背光模组，该背光模组包括光源、导光板以及框架单元，框架单元包括支架和中框。支架设置有相连接的支承部和竖直部，支承部用于承载液晶显示装置的导光板，竖直部远离支承部的一端设置有配合部，配合部靠近导光板的一端设置有配合面，配合面由竖直部靠近导光板的一侧向竖直部远离导光板的一侧倾斜。中框靠近导光板的一端抵压导光板，中框靠近支架的部分设置有倒U型槽，配合部容设于倒U型槽中，配合面与倒U型槽靠近导光板一侧的内表面相抵接。其中，导光板设置在支承部上，光源设置在竖直部上。
其中，配合面为平面或曲面。
其中，支架由铝材制成。
其中，配合部靠近导光板一端的顶部设置有装配角。
其中，配合部远离导光板的一侧设有钩合部，倒U型槽远离导光板的部分设置有钩合槽，钩合部与钩合槽钩合式配合。
其中，配合部远离支承部的一侧与倒U型槽的内表面紧密配合。
为解决上述技术问题，本发明采用的又一个技术方案是：提供一种用于液晶显示装置的框架单元，该框架单元包括支架和中框。支架设置有相连接的支承部和竖直部，支承部用于承载液晶显示装置的导光板，竖直部远离支承部的一端设置有配合部，配合部靠近导光板的一端设置有配合面，配合面由竖直部靠近导光板的一侧向竖直部远离导光板的一侧倾斜。中框靠近导光板的一端抵压导光板，中框靠近支架的部分设置有倒U型槽，配合部容设于倒U型槽中，配合面与倒U型槽靠近导光板一侧的内表面相抵接。
其中，配合面为平面或曲面。
其中，支架由铝材制成。
其中，配合部靠近导光板一端的顶部设置有装配角。
其中，配合部远离导光板的一侧设有钩合部，倒U型槽远离导光板的部分设置有钩合槽，钩合部与钩合槽钩合式配合。
其中，配合部远离支承部的一侧与倒U型槽的内表面紧密配合。
本发明实施例通过在液晶显示装置支架的配合部上设置倾斜的配合面，并将该配合面与中框上的倒U型槽的内表面相抵接。当中框由于挤压导光板而受到导光板施加的一个垂直导光板向上方向的反作用力F1，中框会向远离导光板的方向翻转，从而带动中框上的倒U型槽挤压配合面。由于配合面由支架靠近导光板的一侧向支架远离导光板的一侧倾斜，因此支架会施加给中框一个倾斜于导光板向下的反作用力F2。反作用力F1与反作用力F2相互平衡，从而确保了中框不会由于受导光板的反作用力而翻转。

优选地，支架10由铝材制成，以增强液晶显示装置的散热效果，当然，支架10也可以由其他具有散热功能的材料制成，在此不作限定。
具体而言，支架10包括支承部11和竖直部12。支承部11用于承载液晶显示装置的导光板40。
竖直部12上方设置有配合部121，配合部121上设置有钩合部1211，钩合部1211可以设计为一凸出于竖直部12外表面设置的凸台，也可以设计成其他结构，在此不作限定。配合部121异于钩合部1211的一侧顶部设置有装配角1212，装配角可以为倒圆角，也可以为倒C角，其设置的目的是方便支架10与中框20的装配。装配角1212的下方设置有配合面1213，配合面1213由竖直部12上设置装配角1212的一侧向竖直部12上设置钩合部1211的一侧倾斜。配合面1213可以是一倾斜平面，也可以是一倾斜曲面，其具体结构可视框架单元的结构设计而定，本发明对此不作限定。
在本实施例中，支承部11与竖直部12之间相互连接设置，需要注意的是，其连接方式可以为焊接，也可以为一体成型或其他的连接方式。换句话说，支承部11和竖直部12的连接方式可以视背板组件自身的结构设计而定，本发明对此不作限定。
中框20靠近竖直部12的部分设置有倒U型槽21，倒U型槽21的开口大小与配合部121顶部大小相匹配以允许配合部121容设于倒U型槽21中。倒U型槽21内进一步设置有钩合槽211，倒U型槽21设置钩合槽211一侧的底部设置有钩状部212。中框20远离倒U型槽21的一侧设置有承载部22以及压合槽23。
上面介绍了支架10和中框20的具体结构，下面详细说明支架10和中框20的装配方式。
在本实施例中，配合部121容设于倒U型槽21内，且配合部121远离支承部11的端面与倒U型槽21的内表面紧密配合，钩状部212抵住钩合部1211的下表面以使钩合部1211容设于钩合槽211内。配合面1213抵靠倒U型槽21远离钩合槽211一侧的内表面以实现配合部121与倒U型槽21远离钩合槽211一侧的内表面的配合。当然，也可以在装配角1212与配合面1213之间设置一过渡区域，通过该过渡区域抵接倒U型槽21远离钩合槽211一侧的内表面以实现配合部121与倒U型槽21远离钩合槽211一侧的内表面的配合。配合部121与倒U型槽21远离钩合槽211一侧的内表面的配合方式还可以根据液晶显示装置的设计而灵活的进行设置，在此不作限定。
在本实施例中，液晶显示装置的光源30设置于竖直部12上，其具体连接方式可以是通过导热胶贴附或通过螺丝锁附于竖直部12上，光源30设置的位置及其与支架10的连接方式在此不作限定。
液晶显示装置的导光板40设置在支承部11上，具体地，可以在支承部11靠近导光板40的一面设置缓冲垫（未标示），导光板40设置于该缓冲垫上，以达到更好的装配效果。导光板40远离支承部11的一面与中框20相抵接。优选地，中框20通过压合件60实现与导光板40的抵接，压合件60为一弹性材料且设置于压合槽23内。压合件60与压合槽23之间的配合关系可以为过盈配合，也可以是其它形式，本发明对此不作限定。压合件60下表面抵接导光板40，从而将导光板40固定于支架10和中框20之间。
液晶显示装置的液晶面板50设置于承载部22上，承载部22的具体结构及其与液晶面板50的装配方式可以视液晶显示装置的设计而定，本发明对此不作限定。
以上所述为本发明一实施例用于液晶显示装置的框架单元的结构及各部件之间的连接关系，下面结合图4详细说明本实施例避免中框20外翻的原理，图4是图1所示的框架单元避免中框外翻的原理示意图。
在液晶显示装置的使用过程中，由于中框20挤压导光板40，因此中框20会受到一个导光板40施加的反作用力F1，其方向垂直导光板40平面向上。中框20受F1的作用后，会沿背离导光板40方向翻转。由于中框20翻转过程中会挤压配合面1213，因此中框20将受到一个配合面1213施加的反作用力F2，其方向垂直于配合面1213向下，也就是倾斜于导光板40平面向下。F2与F1相互平衡，因此便可以确保中框20不会因导光板40施加的反作用力而翻转。
本发明实施例在框架单元的支架10的配合部121上设置倾斜的配合面1213，并将该配合面1213与中框20上的倒U型槽21的内表面相抵接。当中框20受导光板40的反作用力F1翻转时，配合面1213会对中框20施加另外一个力F2使得中框20受力平衡，避免了中框20的翻转。本发明实施例能够使支架10和中框20之间的配合更加紧密，有效防止中框20外翻。
需要说明的是，以上所述仅为本发明其中一个实施例，在本发明其他的实施例中，可以将倒U型槽设置在支架的竖直部上，配合部设置在中框上，配合部容设于倒U型槽中；又或者是在支架的竖直部上设置一U型槽，在中框上设置配合部，在配合部远离导光板的一侧设置有配合面，配合面由配合部远离导光板的一侧向配合部靠近导光板的一侧倾斜，通过U型槽和配合部的配合实现支架和中框的配合。由于其他实施例各部件结构、连接方式以及防止中框外翻的原理与上述实施例基本相同，故在此不作赘述。
不难理解，由于本发明其他的实施例均采用了倾斜设置的配合面，故其他实施例也能够使支架和中框之间的配合更加紧密，有效防止中框的外翻。
本发明实施例还提供了一种背光模组，该背光模组包括光源、导光板和上述的框架单元。其中，框架单元包括支架和中框等。如前所述，光源设置于支架的竖直部上，导光板设置在支架的支承部上。竖直部上方设置有配合部，配合部上设置有配合面；中框靠近竖直部的部分设置有倒U型槽。配合部容设于倒U型槽中以实现支架和中框的连接配合，其中，配合面抵接倒U型槽靠近配合部一侧的内表面。由于背光模组各部件的结构和连接方式已经在上文中作了详细说明，故在此不再赘述。
不难理解，由于本实施例背光模组采用了上一实施例所述的框架单元，故而能够使支架和中框之间的配合更加紧密，并有效防止中框外翻。
本发明实施例还提供了一种液晶显示装置，该液晶显示装置包括液晶面板和上一实施例所述的背光模组。其中，液晶面板设置于支架的承载部上。背光模组的框架单元包括支架和中框等。如前所述，液晶显示装置的光源设置于支架的竖直部上，导光板设置在支架的支承部上。竖直部上方设置有配合部，配合部上设置有配合面；中框靠近竖直部的部分设置有倒U型槽。配合部容设于倒U型槽中以实现支架和中框的连接配合，其中，配合面抵接倒U型槽靠近配合部一侧的内表面。由于液晶显示装置各部件的结构和连接方式已经在上文中作了详细说明，故在此不再赘述。
容易理解的是，由于本实施例液晶显示装置采用了上述实施例所述的框架单元，故而能够使支架和中框之间的配合更加紧密，并有效防止中框外翻。
以上所述仅为本发明的实施例，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。
