Description

液晶显示装置及其外框组件
【技术领域】
本发明涉及液晶显示领域，尤其涉及一种液晶显示装置及其外框组件。
【背景技术】
液晶显示（Liquid Crystal Display, LCD）装置具有机身薄、省电、辐射低等众多优点，正全面取代冷阴极射线管显示装置和等离子显示装置等。
液晶显示装置包括液晶显示面板、背光模组和外框。其中，外框包括前框和后框，前框和后框二者之一的侧边四周设置有若干通孔、另一个的侧边四周设置若干螺纹孔。液晶显示面板和背光模组层叠放置后分别自液晶显示面板侧和背光模组侧组装前框和后框使二者的侧边相互重叠且通孔与螺纹孔互相对准，然后用螺钉穿入通孔后并拧入螺纹孔中，前框和后框相对固定，同时，液晶显示面板和背光模组通过外框亦相对固定。
然而，上述组装过程中需拧入大量的螺钉，需浪费较多的人力成本和时间成本，从而带来生产效率较低等弊端。
【发明内容】

其中，牵引固定部上设置一个或多个通孔，背板上对应通孔的位置处设置一个或多个螺纹孔，螺钉穿过通孔拧入螺纹孔。
其中，第二盖体沿第一方向设置导引凸条，锁板的对应位置处设置滑槽，滑槽的长度大于导引凸条的长度，以使锁板相对第二盖体沿第一方向滑动时阻止二者沿垂直于第一方向的第二方向发生位移。
本发明的有益效果是：与现有技术相比，本发明液晶显示装置的外框组件的前框上设置若干包括卡扣部的插置部，后框包括第一盖体、第二盖体和位于二者之间的锁板，第一盖体和第二盖体通过定位装置相对定位，第一盖体、锁板和第二盖体对应于插置部的位置处分别设置第一通孔、第二通孔和卡槽，将前框和后框叠放在一起时，插置部依次插入第一通孔、第二通孔和卡槽，此时，仅需沿第一方向拉动锁板，锁板即可卡持于插置部的卡扣部中，接下来将锁板相对第一盖体或者第二盖体固定，前框和后框即可相对固定，组装过程简单。而且，当外框组件需要拆卸时，仅需将锁板相对第一盖体或第二盖体拆下并沿第一方向的反方向推动锁板，即可将前框自后框中取出，拆卸过程亦非常简单。本发明液晶显示装置的外框组件能够快速组装和拆卸，进而能够提高生产效率。

【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
请参照图1至图5，本发明液晶显示装置包括外框组件10、显示面板20和背光模组30。
外框组件10包括前框11和后框12。
前框11包括第一主体部111和若干插置部114。第一主体部111包括设置开口（未标示）的顶面112和自顶面112的边缘垂直延伸且首尾相接的多条侧壁113。插置部114自侧壁113的底部边缘延伸。插置部114上设置卡扣部115。卡扣部115为凹陷设置的凹槽。卡扣部115的形状可以是方形、U形或者半圆形等。
本实施例中，第一主体部111的顶面112为方形顶面，侧壁113有四条，每条侧壁113上均设置有插置部114。设置于每条侧壁113上的插置部114的数量不受本发明说明书和附图的限制。实际应用中，当液晶显示装置的尺寸较小时，亦可以仅在相对的一对侧壁113上或者其中的三条侧壁113上设置插置部114。
后框12包括第一盖体121、第二盖体122和位于二者之间的锁板123。第一盖体121和第二盖体122的形状与前框11的顶面大致相同，锁板123包括比第一盖体121或第二盖体122略小的第二主体部1231和自第二主体部1231的一端延伸的牵引固定部1232。牵引固定部1232上设置一个或多个通孔1235。牵引固定部1232与第二主体部1231位于同一平面上，为了方便下文描述，将牵引固定部1232的延伸方向定义为第一方向X。
第一盖体121、锁板123和第二盖体122上对应于插置部114的位置处分别设置若干第一通孔1211、第二通孔1233和卡槽1222。第一盖体121和第二盖体122上设置使二者相对定位的定位装置。本实施例中，定位装置为设置于第一盖体121上的凸台1212和设置于第二盖体122上的定位凹槽1221。实际应用中定位装置还可以为设置于第一盖体121上的定位凹槽和设置于第二盖体122上的凸台。定位凹槽1221和凸台1212配合以在第一盖体121或第二盖体122的顶面所在的方向上以及在定位凹槽和凸台延伸的方向上限制第一盖体121和第二盖体122的相对位移。
第一盖体121和第二盖体122通过凸台和定位凹槽相互配合后，位于二者之间的锁板123能够在第一盖体121和第二盖体122之间沿第一方向X平移，其中，锁板123的第二主体部1231沿第一方向X上的尺寸小于第一盖体121和第二盖体122。
为了限制锁板123在垂直于第一方向X的第二方向Y上相对第一盖体121或第二盖体122发生位移，优选地，第二盖体122沿第一方向X设置的相对两边上设置导引凸条1223，锁板123的对应位置处设置滑槽1234。滑槽1234的长度小于导引凸条1223的长度。当第二盖体122、锁板123和第一盖体121依次层叠放置使卡槽1222、第二通孔1233和第一通孔1211的中心正对时，导引凸条1223位于滑槽1234中，且滑槽1234在远离牵引固定部1232的一端留有空隙；使得操作者能够沿第一方向X拉动牵引固定部1232。
显示面板20和背光模组30收容于前框11的顶面112和侧壁113形成的围合结构中。背光模组30的背板31上设置一个或多个与牵引固定部1232上的通孔1235对应的螺纹孔（未标示）。
组装液晶显示装置的过程为：将第二盖体122、锁板123、第一盖体121、背光模组30、显示面板20和前框11依次层叠放置，此时，锁板123的滑槽1234套在第二盖体122的导引凸条1223上，牵引固定部1232凸出第一盖体121和第二盖体122的外侧，第一盖体121的凸台1212插入第二盖体122的定位凹槽1221中，第一通孔1211、第二通孔1233和卡槽1222正对，插置部114依次插入第一通孔1211、第二通孔1233和卡槽1222；接下来，沿第一方向X拉动锁板123，锁板123的第二通孔1233沿第一方向X平移，第二通孔1223的边缘卡入卡扣部115的凹槽中，从而防止插置部自后框12中脱离；进一步地，将锁板123的牵引固定部1232弯折至第二盖体122的外侧，使牵引固定部1232上的通孔1235与背板31上的螺纹孔正对，将螺钉124拧入通孔1235和背板31的螺纹孔中，至此，液晶显示装置的组装过程完成，显示面板20和背光模组30固定于外框组件10中。
前述实施例中，牵引固定部1232最终折叠于第二盖体122的外侧并通过螺钉124拧紧至背光模组30的背板31上。实际应用中，牵引固定部1232亦可通过螺钉固定至第二盖体122上；或者，将牵引固定部1232折叠至第一盖体121的外侧并通过螺钉拧紧至第一盖体121或者前框11上。不论牵引固定部1232最终固定至前框11、第一盖体121、第二盖体122、背板31中的哪一个，锁板123均相对第一盖体121或者第二盖体122固定，前框11、后框12、显示面板20和背光模组30形成一个有机的整体。
与现有技术相比，本发明液晶显示装置的外框组件10的前框11上设置若干包括卡扣部115的插置部114，后框12包括第一盖体121、第二盖体122和位于二者之间的锁板123，第一盖体121和第二盖体122通过定位装置相对定位，第一盖体121、锁板123和第二盖体122对应于插置部114的位置处分别设置第一通孔1211、第二通孔1233和卡槽1222，将前框11和后框12叠放在一起时，插置部114依次插入第一通孔1211、第二通孔1233和卡槽1222，此时，仅需沿第一方向X拉动锁板123，锁板123即可卡持于插置部114的卡扣部115中，接下来将锁板123相对第一盖体121或者第二盖体122固定，前框11和后框12即可相对固定，组装过程简单。而且，当外框组件10需要拆卸时，仅需将锁板123相对第一盖体121或第二盖体122拆下并沿第一方向X的反方向推动锁板123，即可将前框11自后框12中取出，拆卸过程亦非常简单。本发明液晶显示装置的外框组件能够快速组装和拆卸，进而能够提高生产效率。
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。
