本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
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。
本发明提供一种扩散板支撑件，用于安装在背板和扩散板之间，请参看图1和图2，在一实施例中，该扩散板支撑件1包括：固定部12和支撑部11。所述固定部12用于与背板固定；所述支撑部11与所述固定部12连接并向背离所述固定部12的方向延伸。所述支撑部11用于抵触并支撑扩散板；所述支撑部11在受到所述延伸方向1112的压力时产生弹性形变而在所述延伸方向1112缩短。
本实施例所提供的扩散板支撑件1当受到扩散板的挤压时，可以产生弹性形变，从而缓冲该挤压。达到避免该挤压力导致扩散板破裂、导致位于扩散板出光面的液晶面板破裂或者导致扩散板支撑件1断裂。
为了更好的对该扩散板支撑件1的技术特征和有益效果进行说明，将扩散板支撑件1应用于一背光模组来进行描述。
本实施例还提供了一种背光模组，请结合参看图3，在一实施例中，该背光模组包括背板2、灯条3、反光板4、扩散板5和扩散板支撑件1。所述扩散板5固设于所述背板2的顶侧，所述扩散板支撑件1安装于所述背板2与所述扩散板5之间以支撑所述扩散板5。所述灯条3和反光板4也设于所述背板2与所述扩散板5之间，所述背板2上留有安装孔以固定灯条3和反光板4。所述灯条3和反光板4皆安装于所述背板2朝向扩散板5的一侧，灯条3的发光体31经反光板4上的过孔41而穿至所述反光板4朝向扩散板5的一面，以发光照亮扩散板5。反光板4将向背板方向发出的光反射至扩散板5上，以增强扩散板5接收到的光强。
所述背板2上朝向所述扩散板5的面上设有安装结构；反光板4对应该安装结构的位置开设有过孔42以供扩散板支撑件1穿过。
请结合参看图7，所述扩散板支撑件1的固定部12与所述背板2的安装结构固定；所述支撑部11与所述固定部12连接并向背离所述固定部12的方向延伸，以抵触并支撑扩散板5；所述支撑部11在受到所述延伸方向1112的压力时产生弹性形变而在所述延伸方向1112缩短。
本实施例所提供的背光模组，在扩散板5受到安装于其出光面的液晶面板挤压时，可以产生弹性形变，从而缓冲该挤压。达到避免该挤压力导致扩散板破裂、导致位于扩散板出光面的液晶面板破裂或者导致扩散板支撑件1断裂。
本实施例的背光模组中设有的反光板4和灯条3的形状位置关系并不影响背光模组达到上述效果。因此，可以理解的是，在其他实施例中，也可以不采用反光板4或者采用其他形式的灯条和反光板4的安装关系。
本实施例中，所述支撑部11包括：支撑板111和加强筋112。所述支撑板111与所述固定部12连接并背离所述固定部12延伸（即所述延伸方向1112）。所述加强筋112连接于所述固定部12和支撑板111的连接处，以加强所述支撑板111的支撑强度。所述支撑板111从所述支撑板111的延伸末端至与所述加强筋112连接处之间的部位为弹性形变部位1111；所述弹性形变部位1111在所述支撑部11受到所述延伸方向1112的压力时，产生弯折弹性形变使得支撑部11在所述延伸方向1112缩短。本实施例的背光模组，一方面其扩散板支撑件1采用同种材料一体成型即可，因此具有结构简单，易于加工和装配的效果。另一方面，支撑板111的韧性好可以产生弯折弹性形变以避免扩散板5被顶碎；经加强筋加强后的支撑板111具有足够的强度，从而避免支撑板111过于软，而不能起到支撑扩散板5的效果。
当然，在其他实施例中，也可以采用多种材料混合制成。例如，在支撑部11的顶部增加缓冲胶帽，例如支撑部11通过弹性件与固定部12连接等。
本实施例中，所述支撑板111包括与所述固定部12连接的两短边和两长边1114（图中仅标出其中一条长边），该两长边和短边构成矩形。所述加强筋112包括两个，分别连接于所述两长边1114的中间位置，所述加强筋112与所述固定部12连接的底面为半圆状，所述加强筋112在所述延伸方向1112上逐渐缩小；所述支撑板111在所述延伸方向1112上逐渐缩小。本实施例中，两个加强筋112合并后的整体呈锥形，所述支撑板111整体呈V型。
当然，在其他实施例中，加强筋112也可以是连接于两短边处，例如加强筋112呈C形将短边及短边与长边1114的连接处围合。
具体地，本实施例中，支撑板111的板厚在0.6mm至0.8mm之间。由于支撑板111的板厚较薄，一方面可以具有良好的韧性，另一方面可以增强光线透过率，改善由于支撑件遮挡光线而带来的十字交叉式灯影现象。
请结合参看图4和图5，本实施例中，所述扩散板支撑件1的固定部12包括：连接板121和滑扣头123。所述扩散板支撑件1的支撑部11凸设于所述连接板121的顶面1211；所述扩散板支撑件1的滑扣头123凸设于所述连接板121的底面1212。所述滑扣头123包括颈部1231和头部1232，所述颈部1231连接于连接板121和头部1232之间，所述头部1232的轮廓大于所述颈部1231。
所述背板2的安装结构包括设于所述背板2上的基板21和设于所述基板21上对应所述滑扣头123的滑扣槽211；所述滑扣槽211包括相连通的宽槽部位2111和窄槽部位2113。
所述滑扣头123插于所述滑扣槽211的宽槽部位2111时可以自由移动；所述滑扣头123插于所述滑扣槽211的窄槽部位2113时所述连接板121和所述滑扣头123的头部1232分别抵紧于所述基板21的相对两面，使得扩散板支撑件1安装于背板2上。
本实施例中，扩散板支撑件1通过一滑扣结构安装于背板2上，该种连接方式，具有便于安装和拆卸，并且适用于钣金背板和塑胶背板，因此具有较好的通用性。
当然，可以理解的是，在其他实施例中，也可以采用插卡、螺紧或粘接的方案来将扩散板支撑件1安装于背板2上。
请结合参看图6和图7本实施例中，进一步地，所述滑扣槽211在宽槽部位2111和窄槽部位2113的连接处还设有颈槽部位2112。所述颈槽部位2112的最小宽度小于所述滑扣头123的颈部1231最小宽度，用于限制滑扣头123于所述窄槽部位2113。
所述滑扣头123的远离所述连接板121的端面凹设有让位孔1233；所述滑扣头123在从所述宽槽部位2111和窄槽部位2113之间移动时受所述颈槽部位2112的边缘的挤压而向所述让位孔1233内形变，所述滑扣头123在位于所述宽槽部位2111或窄槽部位2113压力消失时恢复弹性。
具体地，本实施例中，所述颈槽部位2112的宽度为2.0mm至2.1mm，而滑扣头123的颈部1231为直径为2.5mm的圆柱体。滑扣头123形成所述让位孔1233的最小壁厚为0.5mm，从而使得滑扣头123具有足够的强度和韧性。上述具体尺寸仅代表一种实施例，并限定本发明仅能采用上述尺寸。
本实施例中，采用上述设计可以将滑扣头123固定于窄槽部位2113，从而达到更牢靠地将扩散板支撑件1安装于背板2上。
进一步地，所述扩散板支撑件1的固定部12还包括定位件122，所述定位件122凸设于所述连接板121的底面1212。所述定位件122在所述滑扣头123插于所述滑扣槽211的窄槽部位2113时插于所述宽槽部位2111内，用于在所述扩散板支撑件1在所述窄槽部位2113内自转时与所述宽槽部位2111的边缘相抵触，而限制扩散板支撑件1的自转角度。当然，在其他实施例中，定位件122也可以与背板上的其他凹槽配合以实现限制扩散板支撑件1的自转角度的目的。
请再次参看图3和图5，具体地，通过上述定位件122与宽槽部位2111的配合，所述扩散板支撑件1的支撑板111的长度方向1113与所述灯条的长度方向32之间的夹角小于等于10°。扩散板支撑件1在此角度范围内旋转不会产生光学不良，满足光学要求。
由于扩散板支撑件1在安装后需要紧固于背板上，为了达到该紧固效果，需要所述扩散板支撑件1的连接板121和滑扣头123的头部1232夹紧所述基板21。通常紧密配合将导致安装困难，为了克服该困难，请再次参看图2，本实施例中，所述扩散板支撑件1的所述连接板121的底面凹陷呈盘状。请再次参看图7，呈盘状的所述连接板121在所述滑扣头123插于所述滑扣槽211的窄槽部位2113时，所述连接板121通过所述反光板4与所述基板21抵压而产生趋向平板状的弹性形变，使得所述连接板121和滑扣头123的头部1232夹紧所述基板21。本实施例所提供的扩散板支撑件1的连接板121具有弹性，从而可以在安装时具有较充足的安装余量使得装配更方便。
具体地，本实施例中，所述连接板121的底面1212呈圆弧面，因此底面1212的周缘为最低点，越往底面1212的中间的位置越高。本实施例中，该底面1212的最低点与最高点的距离差为0.5mm，以具有较好的强度和韧性。上述具体尺寸仅代表一种实施例，并限定本发明仅能采用上述尺寸。
以上仅为本发明的优选实施例，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。
