Description

支撑结构、直下式背光源和显示装置 技术领域
本发明属于显示技术领域，具体涉及一种支撑结构、直下式背光源和显示装置。
背景技术
液晶显示装置已被广泛应用于手机、笔记本、显示器等电子信息产品中。现有的液晶显示装置主要包括液晶显示面板和为液晶显示面板提供面光源的背光源模组。
如图1所示，通常直下式背光源包含背板2、光源4、多个支撑结构30和扩散板1。其中，背板2与扩散板1相对设置；支撑结构30设置在背板2与扩散板1之间；显示面板5置于直下式背光源的扩散板1之上。光源4所发出的光线通过扩散板1提供给显示面板5。随着直下式液晶显示装置尺寸的逐渐增大，为防止扩散板1和显示面板5由于受到自身重力的作用而弯曲下垂，一般会在背板2和扩散板1之间装置多个支撑结构30用于支撑扩散板1和显示面板5，从而获得更佳的显示效果。
发明内容
发明人发现现有技术中至少存在如下问题：支撑结构30多为直接粘到或者钉到背板2上，在长期使用过程中，粘到背板2上的支撑结构30容易松动；在背光源维修过程中，钉到背板2上的支撑结构30拆卸困难。
针对现有的直下式背光源中的支撑结构易松动或难拆卸的问题，提供了一种支撑结构、直下式背光源和显示装置。
本发明实施例采用了以下技术方案：

可选的，所述支撑柱包括主支撑柱和辅助支撑柱，在垂直于上表面的方向上，主支撑柱的高度大于辅助支撑柱的高度。
本发明实施例还提供一种背板，包括用于供根据以上所述的支撑结构的卡勾穿过的安放孔，以及用于卡合所述突起的锁合孔。
可选的，所述安放孔均匀分布于背板上。
本发明实施例还提供一种直下式背光源，包括相对设置的扩散板和上述背板，以及多个位于所述背板与所述扩散板之间的上述的支撑结构。
可选的，所述压条与背板之间设有与所述下表面平行设置的反射片，所述反射片设有与卡勾相对应的安放孔。
可选的，所述背板与所述扩散板之间还包括多个光源，在垂直于扩散板的方向上，所述支撑结构不与所述光源的投影重合。
本发明实施例还提供一种显示装置，包括上述的直下式背光源。
本发明实施例的支撑结构中，采用支撑柱支撑扩散板，采用卡勾穿过背板上的安放孔，然后移动支撑结构以使锁合孔与突起卡合，完成卡合和锁紧的操作。将该支撑结构用于直下式背光源，在长期使用中，支撑结构不易松动；在检修维修时，反向移动支撑结构即可，拆卸容易。本发明实施例的直下式背光源适用于各种显示装置，尤其适用于大尺寸的液晶显示装置。

至少一个卡勾，所述卡勾包括连接部和条状部，所述连接部连接所述条状部和所述下表面，所述条状部上设置有朝向所述下表面的突起。
本实施例的支撑结构中，采用支撑柱支撑扩散板，采用卡勾穿过背板上的安放孔后移动支撑结构以使锁合孔与突起卡合，完成卡合和锁紧的操作。将该支撑结构用于直下式背光源，在长期使用中，支撑结构不易松动；在检修维修时，反向移动支撑结构即可，拆卸容易。本发明实施例的直下式背光源适用于各种显示装置，尤其适用于大尺寸的液晶显示装置。
在一个实施例中，提供了一种支撑结构30，如图2-7所示，包括：
压条303，包括安装后靠近显示屏的上表面和靠近背板的下表面；其下表面压在背板2靠近扩散板1的面上；
支撑柱，设于所述压条303的上表面上，也即靠近扩散板1的面上，用于支撑扩散板1；
至少一个卡勾304，所述卡勾304包括连接部3041和条状部3042，所述连接部3041连接所述条状部3042和所述下表面，所述条状部3042上设置有朝向所述下表面的突起3043。
本实施例的支撑结构30中，采用支撑柱支撑扩散板1，采用卡勾304穿过背板2上的安放孔201后移动支撑结构30以使锁合孔202与突起3043卡合，完成卡合和锁紧的操作。将该支撑结构30用于直下式背光源，在长期使用中，支撑结构30不易松动；在检修维修时，反向移动支撑结构30即可，拆卸容易。本发明实施例的直下式背光源适用于各种显示装置，尤其适用于大尺寸的液晶显示装置。
可选的，如图2所示，所述支撑结构30包括至少两个卡勾304。
通常，压条303被设计成长条状。由于两点能够固定一条直线，在一个压条303上设置两个卡勾304，可以将支撑结构30充分固定。
可选的，如图2所示，所述至少两个卡勾304的条状部3042相互平行设置。
利用相互平行设置的条状部3042，能够便利安装和拆卸。
可选的，如图3所示，所述支撑结构30包括一个卡勾304。
在将单独的卡勾304插入安放孔后，绕着与所述下表面垂直的轴线旋转所述支撑结构30，所述卡勾304的突起3043就能够与锁合孔卡合。
可选的，所述卡勾304的连接部3041设置在所述条状部3042的中央；并且所述条状部3042的两端分别设置有一个所述突起3043。以这样的方式，所述支撑结构30可以更加稳固地安装在背板上。
可选的，所述卡勾304能够相对于所述压板303绕垂直于所述下表面的轴旋转。尽管图3中示出的卡勾304的位置对应于支撑柱301，本领域技术人员能够理解，在使用仅一个卡勾304时，卡勾304可以布置在下表面的任意位置上。所述卡勾304穿过安放孔201旋转一定角度后，突起与锁合孔202卡合。
可选的，所述支撑柱包括主支撑柱301和辅助支撑柱302，在垂直于上表面的方向上，主支撑柱301的高度大于辅助支撑柱302的高度。也就是说，主支撑柱301和辅助支撑柱302的结构类似，主支撑柱301比辅助支撑柱302的高度大一些，设置辅助支撑柱302便于安装与拆卸操作。
在一些实施例中，如图2和3所示，支撑结构30是一体成型的，使用时，横向移动支撑结构30或者转动支撑结构30，以使锁合孔202与突起卡合，完成卡合和锁紧的操作。将该支撑结构用于直下式背光源后示意图如图4、图5所示。在一些实施例中，卡勾304相对于压条303可以转动，使用时，将卡勾304旋转至与压条303平行的位置处，安装至如图7所示的背板2上，然后再转动卡勾304，使卡勾304与压条303呈一定角度，从而使锁合孔202与突起卡合，完成卡合和锁紧的操作。
在一个实施例中，提供了一种背板2，如图6、7所示，包括用于供支撑结构30的卡勾304穿过的安放孔201，以及用于卡合突起的锁合孔202，所述支撑结构30为实施例2的支撑结构30。
也就是说，图6的背板2与图2的卡勾304相对应，图7的背板2与图3的卡勾304相对应。图2的一体成型卡勾304，穿过图6的背板2上的安放孔201，然后将卡勾304向右平行移动，使锁合孔202与突起卡合，完成卡合和锁紧的操作。维修拆卸时，将卡勾304向左平行移动，突起脱离锁合孔202即可。图3的卡勾304相对于压条303可以转动，使用时，将卡勾304旋转至与压条303平行的位置处，穿过图7的安放孔201，然后转动卡勾304，使卡勾304与压条303呈一定角度，使卡勾304转动至图7的锁合孔202，从而使锁合孔202与突起卡合，完成卡合和锁紧的操作。维修拆卸时，反向转动卡勾304，至突起脱离锁合孔202。
可选的，所述安放孔201均匀分布于背板2上。
也就是说，所述背板2与所述扩散板1之间可以设有多个支撑结构30；其中支撑结构30均匀分布于背板2与所述扩散板1之间，以便给显示面板5提供均匀的支撑力。
在一个实施例中，提供了一种直下式背光源，如图2-7所示，包括相对设置的扩散板1和实施例3的背板2，以及多个位于所述背板2与所述扩散板1之间的实施例2所述的支撑结构30。
使用了上述支撑结构30的直下式背光源，在长期使用中，支撑结构30不易松动；在检修维修时，反向移动支撑结构30即可，拆卸容易。本发明实施例的直下式背光源适用于各种显示装置，尤其适用于大尺寸的液晶显示装置。
可选的，所述背板2与所述扩散板1之间还包括多个光源4，在垂直于扩散板1的方向上，所述支撑结构30不与所述光源4的投影重合。
也就是说，支撑结构30对光源4进行避让，支撑结构30安装于背板2上不设光源4的位置处。
可选的，所述压条303与背板2之间设有与所述下表面平行设置的反射片6，所述反射片6设有与卡勾304相对应的安放孔201，用于卡勾304穿过。
也就是说，压条303与背板2之间设有反射片6，反射片6的作用是提高光源4的利用率，为了使卡勾304穿过反射片6进而穿过背板2，相应的在反射片6上也设有安放孔201。
在一个实施例中，提供了一种显示装置，其包括上述任意一种直下式背光源。所述显示装置可以为：液晶显示面板、电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
显然，上述各实施例的具体实施方式还可进行许多变化；例如：压条、支撑柱、卡勾的具体尺寸可以根据直下式背光源的大小进行调整，背板与扩散板之间设置的支撑结构的个数可以根据具体型号进行改变。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
