图3是图2所示背板框架的支架和弯折部的立体结构示意图；
图4是本发明背光模组一实施例的结构示意图；以及
图5是本发明液晶显示装置一实施例的结构示意图。
【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。
请参阅图2和图3，图2是采用本发明实施例背板框架的液晶显示装置的结构示意图，图3是图2所示背板框架的支架和弯折部的立体结构示意图。
在本实施例中，背板框架20包括但不限于支架201和弯折部202。
支架201主要用来支撑和收容光学部材。具体而言，支架201包括底板2011、侧壁2012以及挡墙2013，底板2011的一端和侧壁2012相连接，底板2011用于支撑背光模组的光学部材，挡墙2013设于侧壁2012远离底板2011的一端以用于支撑液晶面板，同时，挡墙2013与光学部材之间还可以夹设有弹性件211，以防止光学部材作平行于挡墙2013和底板2011之间的连线方向的移动，从而避免背板框架20刮伤光学部材。进一步地，底板2011、侧壁2012与挡墙2013配合形成类似于“[”型的容置槽，该容置槽可以容置光学部材的侧边。
弯折部202可以由挡墙2013的主体部分破孔以翻折成型，具体而言，弯折部202自挡墙2013往远离容置槽的方向折成型并紧邻液晶面板的侧边设置，通过弯折部202与挡墙2013的配合，可以在水平方向上限制液晶面板的移动，并配合挡墙2013的支撑作用从而固定液晶面板。弯折部202为多个并间隔设置于挡墙2013上，在本实施例中，弯折部202优选为4个，并两两对称设置在挡墙2013上，当然，只要能同样起到固定作用的一个或者多个弯折部202都可以，本发明对此不作限定。同时，在弯折部202与液晶面板的侧边之间夹设有弹性件211，以防止弯折部202刮伤液晶面板，值得注意的是，弹性件211可以由较柔软的塑胶或者橡胶等弹性材料制得。
背板框架20由多个支架201依序首尾相连以拼接形成，多个支架201的底板2011之间设有固定件（图未示）以配合底板2011固定光学部材，在本实施例中，支架201优选为4个，4个支架201可通过铰接或者螺接组合成一个矩形框架结构，同时，支架201还可以通过旋转弯折嵌套至另一个支架201中，以减小背板框架20在运输过程中的体积。而该固定件可以为一个或多个板块间隔设置以呈“川”字形，通过该固定件的两端分别连接到多个支架201的不同底板2011上，以进一步封装固定光学部材，当然，固定件也可以呈十字形或井字形，在此不作限定。进一步地，本实施例中，支架201和弯折部202组合成的背板框架20采用一体成型，从而可以共用一个模具，减小模具费用。另外，上述背板框架20可以为铝件或者镀锌钢件。
请参阅图4，图4是本发明背光模组一实施例的结构示意图。
在本实施例中，背光模组200主要用来为液晶面板提供光源，该背光模组200包括但不限于背板框架20和光学部材21。背板框架20用来容置和固定光学部材21，光学部材21包括导光板和光学膜片等，具体地，背板框架20的多个支架201依序首尾相连形成容置空间，以使得光学部材21可容置于该容置空间内；多个支架201的多个底板2011之间设有上述的固定件。当然，该固定件还可以是螺丝或铆钉等，在此不作限定，底板2011通过固定件的配合以固定光学部材21。
请参阅图5，图5是本发明液晶显示装置一实施例的结构示意图。该液晶显示装置包括但不限于背光模组200和液晶面板300。其中，背板框架20上设置有一个或多个弯折部202，弯折部202紧邻液晶面板300的侧边设置以固定液晶面板300。
通过上述方式，本发明实施例的背板框架通过底板支撑背光模组的光学部材、挡墙支撑液晶面板以及与挡墙相连接的弯折部配合挡墙固定液晶面板，能够省略胶框，减少模具以及材料费用，从而降低生产成本。
以上所述仅为本发明的实施方式，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。
