Description

一种液晶面板固定组件及显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种液晶面板固定组件及显示装置。
背景技术
在液晶面板的开发中，由于差异化需求的考量，同一显示尺寸的面板具有不同的外观尺寸。特别是不同的面板厂家，由于采用的技术路线不同，面板外形尺寸会有较大的差异。而在背光模组的开发中，为减少模具的开发，降低开发成本，缩短开发周期，通常希望背光模组兼容不同外观尺寸的液晶面板，然而常用的固定方法无法满足这种需求。
发明内容
鉴于现有技术存在的不足，本发明提供了一种能使背光模组兼容不同尺寸的液晶面板的固定组件及显示装置。
为了实现上述的目的，本发明采用了如下的技术方案：
一种液晶面板固定组件，包括方形的框体结构和多个限位块，所述框体结构用于支撑液晶面板，所述框体结构上相邻的两个边上分别设有多组与所述框体结构的内侧面距离不同的固定部，所述限位块可选择性地固定在一组所述固定部上，以形成不同的液晶面板放置区域。
其中，所述固定部包括两个间隔设置的插孔，所述限位块的一面设有两个间隔的凸柱，所述凸柱插入所述固定部内。
或者，所述液晶面板固定组件还包括紧固件，所述固定部包括两个间隔设置的插孔，所述限位块的一面间隔地设有凸柱和通孔，所述凸柱插设于所述固定部内，所述紧固件穿过所述通孔后插设于所述固定部内。
或者，所述液晶面板固定组件还包括紧固件，所述固定部包括两个间隔设置的插孔，所述限位块上间隔地设有两个通孔，所述紧固件穿过所述通孔后插设于所述固定部内。
其中，所述固定部在其所在边的长度方向上间隔设置。
其中，所述限位块转动180°再次固定在同一组所述固定部后，多个所述限位块围成的液晶面板放置区域大小改变。
其中，所述框体结构为中框的水平部分。
其中，所述液晶面板固定组件还包括前框，所述前框将液晶面板按压在所述框体结构上。
其中，所述框体结构顶面凸设有限位柱，所述前框上开设有限位孔，所述限位柱穿设于所述限位孔内。
本发明的另一目的在于提供一种显示装置，包括液晶面板和上述液晶面板固定组件，所述液晶面板的底面放置在所述框体结构上，所述液晶面板的侧壁由所述限位块夹紧进行限位。
本发明通过设计一种液晶面板固定组件，利用框体结构支撑液晶面板，在框体结构的各个边上设有位置可调的限位块，通过改变框体结构各个边上限位块的位置可以很方便地实现对多种尺寸的液晶面板进行固定，省去了需要针对不同尺寸液晶面板设计不同的背光模组的成本，同时也提高了背光模组的兼容性。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。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。
实施例1
参阅图1，本发明的液晶面板固定组件用于对显示装置中的液晶面板1进行限位和固定，包括方形的框体结构10和设于框体结构10上的若干限位块20，框体结构10用于支撑液晶面板1，框体结构10上相邻的两个边上分别设有多组与框体结构10的内侧面距离不同的固定部11，限位块20可选择性地固定在其中一组固定部11上，四周的限位块20间隔地设置，以形成不同的液晶面板放置区域，显示面板1的底面放置在框体结构10上，液晶面板1的侧壁由限位块20夹紧进行限位。框体结构10为显示装置的中框的水平部分。
结合图2和图3，在框体结构10上，设在同一侧的固定部11在其所在边的长度方向上间隔设置，而相邻的两个固定部11到框体结构10的内侧面距离均不同，因此，可以通过将限位块20选择性地固定在相应的固定部11上从而改变多个限位块20的内壁围成的矩形区域的大小。
如图3所示的方向，本实施例的固定部11为两个间隔设置的插孔，固定部11的每两个插孔之间的间距相同，在框体结构10的同一侧，越靠近框体结构10的角部，固定部11距离框体结构10中部的距离越大，使得在调节限位块20的位置的过程中，越朝框体的角部调节限位块20，限位块20实际围成的矩形区域越大，所能夹紧的液晶面板1的尺寸越大。图4a中，限位块20的底面设有两个间隔的凸柱21，凸柱21通过过盈配合的方式插入固定部11内实现限位块20与框体结构10的相对固定。
图4b为本实施例的限位块20的另一种结构，限位块20的底面间隔地设有凸柱21和通孔22，凸柱21插入到固定部11内，紧固件23穿过通孔22后插入到固定部11内完成固定。
图4c为本实施例的限位块20的又一种结构，限位块20上间隔地设有两个通孔22，紧固件23穿过通孔22后插设于固定部11内。
进一步地，前框30设于显示装置的外表面，用于保护显示装置内的结构，前框30将液晶面板1按压在框体结构10上。在框体结构10顶面凸设有限位柱12，相应地，在前框30上开设有限位孔31，限位柱12穿设于限位孔31内，可以对框体结构10作进一步限位，提高液晶面板1固定的可靠性。
实施例2
结合图5所示，进一步地，本实施例的限位块20上的两个凸柱21到限位块20的内侧壁S1、外侧壁S2的距离不等，即内侧的凸柱21距内侧壁S1的距离与外侧的凸柱21距外侧壁S2的距离不等，通过这样的设置，当限位块20拔出后转动180°(即外侧壁S2与内侧壁S1位置对调)再次固定在同一个固定部11后，框体结构10上两条相对侧壁上的限位块20之间的距离发生改变，导致多个限位块20围成的液晶面板放置区域的大小改变，进一步扩大了同一液晶面板固定组件所能兼容的液晶面板的尺寸范围。可以理解的是，实施例1的图4b、图4c中限位块20的另外两种方式也可以作相应的改变，能够在限位块20的外侧壁S2与内侧壁S1位置对调后，限位块20所围成的矩形区域尺寸发生改变。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
