请参阅图 1至图 3 ,为本发明曲面液晶显示器的曲率调整结构的一较 佳实施例，适用于尺寸较小的曲面液晶显示器，该曲面液晶显示器的曲率 调整结构包括：背板 1、 固定安装于背板 1上的一螺柱 3、 对应螺柱 3设 置的两端抵靠于背板 1 上的支架 5、 及与该螺柱 3 螺纹配合的调整螺母 7 ,所述螺柱 3穿过支架 5后与调整螺母 7配合，通过转动调整螺母 7挤 压或放松支架 5 ,借由支架 5挤压或放松背板 1 ,实现对背板 1曲率的调 该曲面液晶显示器的曲率调整结构还包括设置于所述调整螺母 7与支 架 5之间的垫环 9。
所述背板 1采用弹性较好的材料制成，优选的，采用弹簧钢或塑胶制 成，易于发生及恢复弹性变形。 所述背板 1具有底板 110
所述螺柱 3可通过焊接或螺纹连接的方式固定安装于所述背板 1的底 板 11上。 在背板 1未弯曲的状态下，所述螺柱 3的长度足够贯穿支架 5、 垫环 9及调整螺母 7。
所述支架 5设置于该底板 11夕卜侧的中部。 所述支架 5包括架体 51及 连接在架体两端的接触部 53 ,且该支架 5关于所述底板 11的中心对称。 所述架体 51呈弧形，其中心设有一通孔 511以供螺柱 3穿过；所述架体 51围绕所述通孔 511周缘设置有环形凸台 513 ,所述螺柱 3亦穿过该环形 凸台 513 ,凸出于所述支架 5以外；所述接触部 53抵紧于所述背板 1的底 板 11上。 接触部 53呈弧形设置，以更好与背板 1的底板 11进行接触。 所述架体 51上设置加强筋 515 ,以加强强度。
所述支架 5采用刚度与强度均较高的材料制成，其刚度与强度大于所 述背板 1的材料刚度与强度。
所述调整螺母 7包括螺接部 71、 及连接该螺接部 71的手柄 730 所述 螺接部 71与所述螺柱 3的螺纹配合，在本实施例中该螺接部 71呈外六角 形。 所述手柄 73用于旋转所述螺接部 71 ,达到方便、 省力的目的。
所述垫环 9位于所述调整螺母 7与支架 5的架体 51之间，套在所述 环形凸台 513上，且该垫环 9的厚度大于所述环形凸台 513的高度，其所 起的作用是间接的增大所述调整螺母 7与架体 51之间的接触面积。
图 1中，背板 1处于未弯曲状态，呈平面状，此时曲面液晶显示器可 作为平面液晶显示器使用。 当手动旋转所述手柄 73 时，带动调整螺母 7 转动，同时所述调整螺母 7的旋接部 71沿与其螺纹配合的螺柱 3相对上 升，调整螺母 7挤压支架 5 ,所述螺柱 3相对于调整螺母 7与支架 5下 降。 由于所述螺柱 3固定安装于背板 1的底板 11上，所述背板 1在螺柱 3 的牵引下，同时相对于支架 5下降，即趋近于所述支架 5。 又由于所述支 架 5两端的接触部 53抵紧于所述背板 1的底板 11上，且支架 5的材料刚 度与强度大于背板 1的材料刚度与强度，在所述螺柱 3的牵引与所述支架 5的挤压共同作用下，所述背板 1发生弹性变形，并随所述调整螺母 7的 转动圈数不同而呈弯曲程度不同的弧形。 所述调整螺母 7转动圈数越多， 则背板 1越趋近于支架 5 ,直至如图 3所示，所述背板 1与所述支架 5的 架体 51的弧形曲线拟合。 请参阅图 4 ,具有该曲面液晶显示器的曲率调整 结构的曲面液晶显示器适应所述背板 1 的弯曲，整体呈曲面状，其曲率随 所述调整螺母 7转动圈数的不同而发生变化，使得用户能够根据观看需 要，随时、 方便的进行曲面液晶显示器曲率的调整。
同理，反方向旋转所述调整螺母 7的手柄 73 ,调整螺母 7的螺接部 71沿与其螺纹配合的螺柱 3向外移动，调整螺母 7放松支架 5 ,所述背板 1得以放松，即可减小曲面液晶显示器的弯曲程度，直至恢复平面状态。
请参阅图 5 ,为本发明曲面液晶显示器的曲率调整结构的另一较佳实 施例，适用于尺寸较大的曲面液晶显示器。 为使尺寸较大的曲面液晶显示 器的背板 Γ变形均匀，可在背板 Γ的底板 1 Γ上均匀排布多个支架 5， ,并 采用自动调整方式代替手动调整方式以保证对每个支架的调整的同步，从 而保证对曲面液晶显示器的曲率调整的一致性。 与上述实施例不同，在本实施例中，增设一动力齿轮 20 ,调整螺母 7' 包括与螺柱 3'螺纹配合的螺接部 71 '、 及啮合连接该螺接部 71 '的调整齿轮 73' ,该调整齿轮 73'用于与所述动力齿轮 20啮合。
具体的，所述螺柱 3，、 支架 5，与调整螺母 7，均为三个，其依次等间距 排列，位于中间的调整螺母 7'的调整齿轮 73'用于与动力齿轮 20啮合，且 所述位于中间的调整螺母 7'的调整齿轮 73'分别与相邻的调整齿轮 73'通过 一传动齿轮 40进行动力传递。
所述动力齿轮 20可连接在电动马达或液压马达等自动动力源（未图 示）上。 开启自动动力源后，所述动力齿轮 20带动与其啮合的位于中间 的调整螺母 7'的调整齿轮 73'转动，所述位于中间的调整齿轮 73'分别通过 与其啮合的传动齿轮 40带动相邻的调整齿轮 73'及与其啮合连接的螺接部 71 '同步转动。 三个调整螺母 7'同时进行转动，且三者的转动速度与转动 圈数均相同，所述背板 Γ在三个支架 5'与三个螺柱 3'的共同作用下，弯曲 变形均匀，从而使得曲面液晶显示器的显示效果更佳。
综上所述，本发明的曲面液晶显示器的曲率调整结构，将螺柱固定于 背板上、 将弧形支架两端抵紧于背板上，并设置与螺柱螺纹配合的调整螺 母，通过转动调整螺母挤压或放松支架，借由支架挤压或放松背板，实现 对背板曲率的调节，从而使得曲面液晶显示器的曲率方便可调，能够提高 产品对巿场的吸引力，且结构较简单，易实现。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术 方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形 都应属于本发明权利要求的保护范围。
