技术领域technical field

本发明涉及天线技术领域，特别涉及一种天线传动装置。The invention relates to the technical field of antennas, in particular to an antenna transmission device.

背景技术Background technique

基站天线在工作时通常需要相对于水平线向下倾斜一定的角度，此倾角的大小可改变天线的辐射范围。目前，天线下倾角的调节主要由机械下倾角和电下倾角两种方式，电下倾角可通过远程电调控制，成本低，因此得到越来越广泛的应用。The base station antenna generally needs to be tilted downward at a certain angle relative to the horizontal line during operation, and the size of the tilt angle can change the radiation range of the antenna. At present, there are two main ways to adjust the antenna downtilt angle: mechanical downtilt angle and electrical downtilt angle. The electrical downtilt angle can be controlled by remote electric adjustment, and the cost is low, so it is more and more widely used.

随着移动通信终端用户数量在的不断增加，往往要求同根天线需要有更多数量的通信频段，而每个通信频段的电下倾角均需独立控制，通过驱动其对应的移相器传动机构实现电下倾角的的改变。传统的传动装置中，通常采用一个驱动电机对应一个移相器传动机构，此种方式由于控制电路与电机的数量多，势必造成成本高，结构复杂，空间占用大和可靠性低等问题。As the number of mobile communication terminal users continues to increase, it is often required that the same antenna needs to have more communication frequency bands, and the electrical downtilt of each communication frequency band needs to be independently controlled by driving its corresponding phase shifter transmission mechanism. Changes in electrical downtilt. In traditional transmission devices, one drive motor is usually used to correspond to one phase shifter transmission mechanism. Due to the large number of control circuits and motors, this method will inevitably cause problems such as high cost, complex structure, large space occupation and low reliability.
