Description

一种带有旋转模块手机的天线结构 技术领域
本实用新型涉及一种天线结构,特别涉及一种可以 覆盖较宽的通讯频段的带有旋转模块手机的天线结构 。
背景技术
随着手机的发展，现在出现了一种带旋转模块的手机，手机的旋转模块内设有金属块，金属块的旋转会导致天线环境的变化，常规天线在此变化的天线环境中会产生频偏和效率变化的问题，如果在带旋转模块手机上应用常规天线，势必会出现天线效率低和通信频段窄的现象，天线性能不理想，手机通讯受限。
实用新型内容
本实用新型提供一种带有旋转模块手机的天线结构，具有两种辐射模式，形成两个谐振点，可以覆盖较宽的通讯频段。
为了解决技术问题，本实用新型采取以下技术方案：
一种带有旋转模块手机的天线结构，包括支撑手机主体结构的支撑金属板和位于旋转模块内的旋转金属块，旋转金属块的两端通过转轴与支撑金属板连接，旋转金属块与支撑金属板形成长条状的缝隙，支撑金属板上设有手机主板。所述缝隙中设有天线分支，手机主板上设有射频连接器，天线分支分别与射频连接器和支撑金属板电连接。
所述天线分支与射频连接器之间设有馈入引脚，天线分支与射频连接器通过馈入引脚连接。
所述天线分支与支撑金属板之间设有短路引脚，天线分支与支撑金属板通过短路引脚连接。
所述支撑金属板为凹形，旋转金属块位于凹陷位置中 。
所述转轴位于旋转金属块两端的中心位置，旋转金属块绕转轴为中心旋转；或所述转轴位于旋转金属块两端的偏心位置，旋转金属块绕转轴为偏心旋转。
本实用新型的天线分支通过馈入引脚连接主板上的射频连接器馈入信号，形成天线，产生谐振，天线分支同时作为馈入分支，耦合到缝隙，激励起缝隙谐振，形成缝隙天线，这样形成两个谐振点，两种辐射模式，此天线结构可以覆盖较宽的通讯频段。在旋转金属块动作时，因为缝隙长度不变，天线分支长度不变，天线频偏较小，天线性能有保证。
附图说明
图1为本实用新型中支撑金属板和旋转金属块的结构示意图；
图2为本实用新型结构示意图。
图中标号所示为：1-支撑金属板，2-旋转金属块，3-转轴，4-缝隙，5-手机主板，6-射频连接器，7-天线分支，8-馈入引脚，9-短路引脚。
具体实施方式
为了便于本领域技术人员的理解，下面结合附图对本实用新型作进一步的描述。
如图1所示，一种带有旋转模块手机的天线结构，包括支撑手机主体结构的支撑金属板1和位于旋转模块内的旋转金属块2。支撑金属板1为凹形，旋转金属块2位于凹陷位置中，旋转金属块2的两端通过转轴3与支撑金属板1连接。转轴3位于旋转金属块2两端的中心位置，旋转金属块2绕转轴3旋转为中心旋转，或转轴3位于旋转金属块2两端的偏心位置，旋转金属块2绕转轴3旋转为偏心旋转。旋转金属块2与支撑金属板1之间形成长条状的缝隙4，在旋转金属块2旋转时，缝隙4的长度是不变的。
如图2所示，支撑金属板1上设有手机主板5，手机主板5上设有射频连接器6，在缝隙4中设有天线分支7。射频连接器6与天线分支7之间设有馈入引脚8，支撑金属板1与天线分支7之间设有短路引脚9，天线分支7分别通过馈入引脚8和短路引脚9与射频连接器6和支撑金属板1电连接。支撑金属板1作为整个的接地系统，天线分支7通过短路引脚9与接地系统连通。
本实施例在工作时，天线分支7通过射频连接器6和馈入引脚8馈入信号，形成天线，产生谐振，天线分支7同时作为馈入分支，耦合到缝隙4，激励起缝隙谐振，形成缝隙天线。两个谐振点的形成形式是不一样的，这就会形成两种辐射模式，此种天线结构就相当于覆盖了个通讯频段，覆盖的通讯频段更宽。在旋转金属块2动作时，因为缝隙4长度和天线分支7长度均不变，天线频偏较小，天线性能有保证。
上述实施例为本实用新型的较佳的实现方式，并非是对本实用新型的限定，在不脱离本实用新型的发明构思的前提下，任何显而易见的替换均在本实用新型的保护范围之内。
