Abstract

The invention provides an electric adjustable antenna adjustment mechanism, which includes a transmission module and a motor module detachably connected with the transmission module; the motor module includes a shift motor and an electric adjustment motor; The gear assembly includes a shift gear; each transmission assembly includes: a transmission screw, a transmission gear, and a transmission nut; the transmission gears of multiple groups of transmission assemblies are arranged at intervals on the shifting motion stroke of the shift gear, so that the shift gear can selectively It meshes with the transmission gear of one of the transmission components. When the shift gear is driven by the electric motor to rotate, it drives the meshed transmission gear and the corresponding transmission screw to rotate, so that the corresponding transmission nut moves linearly along the transmission screw to perform electric adjustment. . The electronically adjustable antenna adjusting mechanism of the present invention can drive the movement of multiple sets of transmission components through a group of motor modules and a shift gear, thereby driving the electric adjustment of the multi-band antenna by the phase shifter. The entire adjusting mechanism occupies a small space and is easy to operate. Simple and efficient.

Description

technical field [0001] The invention relates to the field of mobile communication base station antennas, in particular to an electric adjustable antenna adjustment mechanism. Background technique [0002] As the terminal of the mobile communication network, the mobile antenna carries the dual functions of electromagnetic wave transmission and reception, that is, the carrier of mobile communication signal transmission, and its application effect directly determines the quality of the mobile communication network. Among them, the electric adjustable antenna is used The electronically adjustable downtilt angle mobile antenna is widely used in mobile communication base stations because the electronically adjustable antenna can reduce call loss, reduce interference, and adjust the downtilt angle with high precision. [0003] In the mobile communication system, in order to optimize the coverage of the wireless signal in the service area and to suppress the mutual interference of t...
