具体的, 所述安装件 99具有一安装部 991及连接该安装部 991的连接 部 993, 该安装部 991呈平面状, 通过螺钉 20固定安装于底板 111的中间 位置上, 该连接部 993 固定连接于座体 91或导轨 93上, 进一步的, 该连 接部 993以烊接或螺紋连接的方式固定连接于座体 91或导轨 93上。
所述一对滑块 97位于安装件 99的两侧, 并相对于所述安装件 99对称 设置。 特别需要指出的是, 该对滑块 97反向设置, 以实现转动丝杠 95时, 该对滑块 97能沿导轨 93向相反的方向滑动;每一滑块 97具有一导引面 971, 且该导引面 971 为孤面或斜面, 其朝向对应的凸起 113设置。 转动丝杠 95 时, 该对滑块 97沿导轨 93 向相反的方向滑动, 所述导引面 971分别从所 述一对凸起 113的内侧逐渐挤压相应的凸起 113, 使得所述底板 111发生弯 曲。
所述每一导轨 93的横截面呈倒 L形, 其具有一平面导引部 931, 该对 导轨 93的导引部 931相对设置; 所述滑块 97对应设有一对滑槽 973, 以分 别与导轨 93 的导引部 931 配合滑动, 所述每一滑块 97设有一螺丝孔 975 以与丝杠 95啮合,通过转动丝杠 95促使该对滑块 97进行相反方向的滑动。
所述丝杠 95可通过手动或配备电动马达、液压马达等动力源(未图示) 的自动方式带动其转动, 优选的, 所述丝杠 95通过配备电动马达、 液压马 达等动力源的自动方式带动其转动。
图 3、 图 4中, 曲面背板 11处于未弯曲状态, 呈平面状, 此时曲面液 晶显示装置可作为平面液晶显示装置使用。 当开启动力源带动所述丝杠 95 转动时, 如图 5、 图 6所示, 与所述丝杠 95啮合的一对滑块 97配合所述导 轨 93 向相反方向滑动, 逐渐趋近于底板 111上对应的一对凸起 113, 直至 所述导引面 971从所述一对凸起 113的内侧逐渐挤压相应的凸起 113, 由于 所述安装件 99的安装部 991通过螺钉 20固定安装于底板 111 的中间位置 上, 且所述导轨 93的材料刚度与强度大于曲面背板 11的材料刚度与强度, 在所述导引面 971对凸起 113的挤压作用下, 所述底板 111发生弯曲。所述 丝杠 95的转动圈数越多, 所述导引面 971对凸起 113的挤压幅度越大, 相 应的所述底板 111的弯曲曲率越大。 如图 10所示, 该曲面液晶显示装置的 其它部件适应曲面背板 11的底板 111的弯曲, 整体呈曲面状, 其曲率亦随 着所述丝杠 95转动圈数的不同而发生变化, 使得用户能够根据观看需要, 快速、 方便的进行曲面液晶显示装置曲率的调节。
同理, 反方向转动丝杠 95, 与所述丝杠 95啮合的一对滑块 97配合所 述导轨 93向相反方向滑动, 逐渐远离底板 111上对应的一对凸起 113, 所 述导引面 971逐渐放松对应的凸起 113, 从而所述底板 111得以放松, 即可 减小曲面液晶显示装置的弯曲曲率, 直至恢复平面状态。
综上所述, 本发明的曲面液晶显示装置, 在曲面背板的底板上安装具 有丝杠、 导轨、 与一对滑块的支架, 并在底板上对应该对滑块设置一对凸 起, 通过转动丝杠带动该对滑块挤压或放松对应的凸起, 使曲面背板的底 板的曲率发生变化, 实现对曲面液晶显示装置曲率的方便、 快速调节, 能 够提高产品对市场的吸引力, 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。
