附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例一提供的背板结构的背板示意图；
图2为本发明实施例一提供的背板结构的支架示意图；
图3为本发明实施例一提供的背板结构示意图；
图4为本发明实施例一提供的曲面显示器示意图；
图5为本发明实施例二提供的背板结构示意图；
图6为本发明实施例二提供的背板结构背板中线位置的剖视图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明实施例一提供的背板结构的背板示意图，如图所示，背板10为平面薄板状片材，背板10包括底边102、顶边104及背板中线106，底边102与顶边104相对设置，分布于背板中线106两侧并与背板中线106的距离相同。一种实施方式中，背板10为材质为环氧树脂的薄板状片材，当然，背板10的材质也可为环氧树脂、玻璃钢、金属、聚合物膜、陶瓷或碳纤。背板10表面安装支架20后将被弯折成曲率半径均匀的曲面。
图2为本发明实施例一提供的背板结构的支架示意图，如图所示，支架20为曲面状结构，支架20包括第一边202、第二边204及支架中线206，第一边202与第二边204相对设置，分布于支架中线206两侧并与支架中线206 的距离相同。支架20的第一边202所在一端设为第一区域，并设置第一区域的曲率半径为R；支架20的第二边204所在一端设为第二区域，并设置第二区域的曲率半径为(R-R0)，支架20的曲率半径由第一区域向第二区域均匀过渡，即支架20的曲率半径由第一边202向第二边204均匀减小。一种实施方式中，支架20为不锈钢板，当然，支架20也可为铝合金板、电镀锌钢板或热镀锌钢板。
结合图3，支架20采用多个固定件安装于背板10靠近底边102一侧，第一边202与底边102重合，支架20弯曲背板10形成曲面，其中固定件为螺钉、铆钉、双面黏胶、拉钉或卡扣。背板10被支架20弯曲后，理论上背板10各位置的曲率半径值及变化趋势与支架20的曲率半径接近，即底边102的曲率半径理论值为R，顶边104的曲率半径理论值为(R-R1)，其中R1的值受R0的值影响；由于背板10的回弹性导致的远离支架20的一侧，即顶边104的回弹力抵消了部分支架20提供的支持力，导致实际背板10的顶边104的曲率半径为(R-R1+R2)，底边102的曲率半径为R。
通过采用CAE仿真技术计算出R0的值，使R1与R2的值接近并相互抵消，使背板10的底边102及顶边104的曲率半径均近似达到目标曲率半径R，得到背板10的各位置曲率均匀且近似相等。
本发明实施例一提供的背板结构将支架20安装于背板10的靠近底边102的一侧，通过将支架20的第一区域设置于支架20的第一边202所在端，第二区域设置于支架20的第二边204所在端，利用第一边202与第二边204的曲率半径差值抵消背板10的顶边104由于回弹特性造成的曲率变化，得到的背板10各位置曲率均匀且相等，为后一步装配超薄且曲率均匀的曲面显示器提供了外观美观并满足使用要求的背板结构。
图4为本发明实施例一提供的曲面显示器示意图，如图所示，曲面显示器由本发明实施例一提供的背板结构与显示面板装配而成。显示面板包括反射片40、导光板50、光学膜片60及液晶玻璃70，显示面板与背板结构之间通过粘接、镶嵌、磁性吸附或真空吸附的方式连接，以形成一显示主体，并采用中框30与前框80固定显示主体。
本发明实施例一提供的曲面显示器设备满足超薄设计的要求，有效改善了 超薄背板回弹引起的曲率不均匀问题，背板直接做外观零件，设备外观美观，给予消费者强力的视觉冲击。
图5为本发明实施例二提供的背板结构示意图，如图所示，与实施例一的区别在于，支架20安装于背板10的中间位置，支架中线206与背板中线106重合。支架20的支架中线206所在的中间部分设为第一区域，并设置第一区域的曲率半径为R；第二区域的数量为两个，两个第二区域分别位于支架20的相对的第一边202与第二边204所在的两端，且对称分布在第一区域的两侧，并设置第二区域的曲率半径为(R-R0)。支架20的曲率半径由支架中线206向支架20的第一边202与第二边204分别均匀减小。
背板10被支架20弯曲后，理论上背板10各区域的曲率半径值及变化趋势与支架20的曲率半径接近，即背板中线106的曲率半径理论值为R，底边102及顶边104的曲率半径理论值均为(R-R1)，其中R1的值受R0的值影响；由于背板10的回弹性导致的远离支架20的两侧，即底边102及顶边104的回弹力抵消了部分支架20提供的支持力，导致实际背板10的底边102及顶边104的曲率半径均为(R-R1+R2)，背板中线106的曲率半径为R。
通过采用CAE仿真技术计算出R0的值，使R1与R2的值接近并相互抵消，使背板10的底边102、顶边104及背板中线106均近似达到目标曲率半径R，背板10的各位置曲率均匀且近似相等。
本发明实施例二提供的背板结构将支架20安装于背板10的中间位置，支架中线206与背板中线106重合，通过将支架中线206所在的中间部分设为第一区域，两个第二区域分别位于支架20的相对的第一边202与第二边204所在的两端，，利用第一边202及第二边204部分与支架中线206的曲率半径差值抵消背板10的底边102及顶边104由于回弹特性造成的曲率变化，得到的背板10各位置曲率均匀且相等，为装配超薄且曲率均匀的曲面显示器提供了外观美观并满足使用要求的背板结构。
一种实施方式中，在背板10与支架20相接触的位置处，背板10表面设有两个对称的凸起108，支架20表面设有两个对称的凹槽208，凸起108与凹槽208配合，使支架20与背板10相互定位。图6为本发明实施例二提供的背板结构在支架中线106及背板中线206处的截面图，如图所示，两个凸起108 与两个凹槽208相互配合，将背板10与支架20的相对位置固定。凸起108与凹槽208的设计有利于支架20弯曲背板10成预设曲面并保持背板10的曲率，同时利于支架20与背板10在装配过程中的相互定位。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易的想到各种等效的修改或替换，这些修改或替换都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
