The invention relates to the field of mobile communication base station antennas, and discloses an electric adjustable antenna transmission switching device and a base station antenna, comprising: a transmission mechanism including a screw, a transmission shaft, a transmission gear and a first driving member; several screws are arranged side by side, and the screw and the lower The inclination adjustment devices are connected in one-to-one correspondence; the first end of the screw rod is selectively engaged with the first end of the transmission shaft; any transmission shaft is sleeved with a transmission gear, and the transmission gear and the transmission shaft rotate integrally, and the transmission shaft is aligned with the transmission gear along the shaft. The first driving member is used to simultaneously drive several transmission gears to rotate; the switching mechanism is arranged at the second end of the transmission shaft, and is used to push one of the transmission shafts to move axially and connect with the corresponding screw. The electronically adjustable antenna transmission switching device and the base station antenna provided by the present invention are arranged in a tiled manner, which avoids occupying a limited height space of the antenna, thereby reducing the installation space and reducing the complexity of antenna installation and maintenance.
Description
technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to an electric adjustable antenna transmission switching device and a base station antenna. Background technique [0002] As the final control terminal of the mobile communication network, the antenna of the communication base station makes the final adjustment to the network provided to the user. The electric downtilt function of the electric adjustable antenna can meet the needs of the same type of antenna in different use areas and different communication load areas, and realize remote control and adjustment of the downtilt angle, so as to provide greater network capacity, reduce communication interference, and reduce labor costs. . [0003] With the increase in the number of mobile communication users, the demand for communication capacity of the communication network is increasing. It is often required that the same antenna can meet the requirements of...
