为了使本技术领域的人员更好地理解本发明方案，下面结合附图和实施例对本发明作进一步的详细说明。
请参阅图1和图2，图1是本发明实施例的结构示意图，图2是图1所示的装置实施方式的结构爆炸图。
本发明实施例提供一种电调天线传动选择切换装置，用于基于两组电机连接驱动多个下倾角调整装置，并实现在各个下倾角调节装置之间的选择切换。本发明的传动切换装置包含三大部分：传动机构，选择切换机构，从动机构。所述从动机构用于把从动电机的扭矩转化为水平运动，并传递到下倾角调节装置，实现下倾角角度控制。所述的选择切换机构用于在不同的下倾角调节装置之间进行自由的选择切换，其中包含有离合机构，利用离合机构来实现在从动丝杆之间的啮合与脱离。
所述传动机构中主要设置一组多级传动齿轮，其中1个齿轮接受 外部动力输入，至少2个齿轮与所述切换选择机构的离合零件相连接，实施例中传动机构包含：从动动力输入转接头1，多级传动齿轮组2，动力输入齿轮3，切换动力输入转接头8，切换动力输入齿轮9。所述的多级传动齿轮组中的齿轮分为动力传递齿轮和动力输出齿轮。
所述选择切换机构包含：选择螺杆10，切换选择零件11，离合零件4，离合弹簧5。所述离合零件4和所述离合弹簧5按照方案所需采用6组，也可以按照具体需求进行数量调整，其数量大于5组即能达到节约成本、节省空间的目的。
所述从动机构包含：从动螺杆6，从动内螺纹滑块7。从动螺杆6两头进行固定，能够对与其相连接的从动内螺纹滑块7提供更好的强度支撑，与扭力传递，确保从动内螺纹滑块7平稳的在从动螺杆6上进行轴向运动。
所述从动动力输入转接头1，用于与一颗电机进行连接，其采用插头插座模式，可以方便的安装、拆卸。接收外部动力输入，通过动力输入齿轮3把动力输送给多级传动齿轮组2。
所述多级传动齿轮在接受外部动力输入的传动齿轮两侧排布，所述动力传递齿轮与动力输出齿轮可以是为奇数齿轮201也可以为偶数齿轮202。
优选地，奇数齿轮201与接受外部动力输入的齿轮转向相反，偶数齿轮202与接受外部动力输入的齿轮转向同向。则奇数齿轮201的转向与接受外部传动输入齿轮转向相反，从动螺杆的转向与动力输入齿轮的转向相反；偶数齿轮202的转向与接受外部传动输入齿轮转向 相同，从动螺杆的转向与动力输入齿轮的转向相同。即：
所述离合零件连接奇数传动齿轮时，所述从动螺杆与接受外部动力输入的齿轮转向相反。
所述离合零件连接偶数传动齿轮时，所述从动螺杆与接受外部动力输入的传动齿轮转向相同。
具体实施时，根据实际需要，通过选择连接奇数传动齿轮和/或偶数传动齿轮，可以使所述全部从动螺杆转向同向，也可以使依次相邻的从动螺杆转向相反。
参见图5，本发明实施例使用的下倾角调节装置运动方式是相同的，所以需要的是同向运动的滑块，因此选用的动力输出齿轮是动力输入齿轮3两侧的奇数齿轮201，偶数齿轮202作为动力传递齿轮，动力输出齿轮的转向一致，这样电机的转向就不需要频繁变更，同时下倾角调整装置的运动方向也是一致，在基站天线整机设计布局上更清晰。当从动电机输入动力时，多级传动齿轮组2的所有齿轮都进行转动。
所述多级传动齿轮组2中的动力输出齿轮与所述离合零件4一一对应连接。动力输出齿轮与所述离合零件4一直保持啮合状态，当从动电机输入动力时，所有的离合零件开始转动。
所述切换动力输入转接头8与另外一颗电机进行连接，其用于接收选择切换所需的动力。实施例采用锥齿轮实现动力输入齿轮9和选择螺杆10的连接，以便改变传动方向，切换动力输入齿轮9与一组锥齿轮相连接，锥齿轮组中的一个与切换动力输入齿轮9相连接，另一 个与选择螺杆10相连接。这样选择螺杆10的转动方向与切换动力输入齿轮9的转动方向成90°夹角。所述选择螺杆10用于支撑、控制切换选择零件11的轴向运动，控制切换选择零件11停止在指定位置。选择螺杆10为外螺纹结构，切换选择零件11为内螺纹结构，两者互相连接，选择螺杆10的转动推动切换选择零件11沿着选择螺杆10的轴向进行往复运动，并把切换选择零件11停在指定位置，选择螺杆10需要一定的强度，用于支撑切换选择零件11推动所述离合零件4时所受的阻力。所述切换选择零件11所停的位置与离合零件4一一对应，其上的凸台对齐离合零件4。
参见图4，所述离合零件4，采用的圆筒对称结构，其可以在底座的套筒内进行灵活的反复活动，在其初始位置时，其上的凸台401与所述从动螺杆6的凹槽处于断开关系，离合零件4的转动无法传递到从动螺杆6上。在离合零件4的另外一端，采用的多边形对称凸台结构，其目的是与所述的从动螺杆6的凹槽能够顺利的滑入，顺利的脱出，能够卡住从动螺杆6进行旋转。在离合零件4凸台401上套着所述离合弹簧5，由所述离合弹簧5提供离合零件4与从动螺杆6断路所需推力。
所述切换选择零件包含至少一个凸台结构1101，当凸台结构1101运动到某一个所述离合零件位置时，其凸台结构1101把所述离合零件顶到啮合位置，于是离合零件与从动螺杆完成啮合，实现动力输出齿轮与从动螺杆的的连接。优选的，所述切换选择零件的凸台结构1101，可以为一个，或者多个，其目的是为了控制切换选择零件的轴向平移 的距离，进而可以控制所述电调天线传动选择切换装置的宽度尺寸。当所述的切换选择零件的凸台结构1101运动到所选择的离合零件位置时，所述切换选择零件的凸台结构1101把所述离合零件顶起，使离合零件的多边形凸台结构1101插入到从动螺杆的凹槽内，实现离合零件与从动螺杆的啮合。
参见图3，实施例中所述切换选择零件11有对称的两个三角形凸台结构1101，三角形凸台结构1101采用大夹角三角形结构，三角形的两边为大夹角(实施例中大于120°)，其目的是在顶所述离合零件4时的阻力不会太大。三角形的顶点为顶离合零件4的功能部位。
所述切换选择零件11停在指定位置上时，所述切换选择零件11上的三角形凸台结构1101把离合零件4朝前顶，压缩所述离合弹簧5，克服弹簧阻力，于是所述离合零件4上的凸台401插入到从动螺杆6的凹槽内，完成离合零件4与从动螺杆6的连接。
所述的切换选择零件11离开指定位置时，离合零件4在离合弹簧5弹力的作用下，退回到初始位置，离合零件4上的凸台401从从动螺杆6的凹槽中脱离，离合零件4与从动螺杆6断开连接。
当切换动力开始输入时，从动动力停止输入，当切换选择零件11完成切换后，从动动力重新开始输入。从动动力、切换动力两者之间切换输入。
通过所述选择螺杆10的运动、停止，来实现某一离合零件4与对应从动螺杆6的断开、啮合，最终实现从动动力到某一根从动螺杆6的动力输入、停止。
以上内容是结合具体实施例对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
