Title:
ELECTRIC DOWNTILT ANGLE ADJUSTMENT APPARATUS AND BASE STATION ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/179334
Kind Code:
A1
Abstract:
The present invention relates to the technical field of antennas, and in particular, to an electric downtilt angle adjustment apparatus and a base station antenna. The electric downtilt angle adjustment apparatus comprises a position selection transmission assembly and a phase shift assembly. The position selection transmission assembly comprises a support frame, a moving switching mechanism, a transmission gear, and a second guide shaft. The second guide shaft is mounted on the support frame, and multiple transmission intermediate wheels are mounted on the second guide shaft at intervals, the transmission gear being configured to drive the transmission intermediate wheels to rotate. The moving switching mechanism is mounted on the support frame, and the moving switching mechanism is used to drive the transmission gear to move and switch among the multiple transmission intermediate wheels. A driving member is disposed on the moving switching mechanism, and the driving member is used to drive the transmission gear to rotate. The phase shift assembly comprises multiple driven members, the multiple driven members each being used to connect to a corresponding phase shifter to implement adjustment of tilt angles of the phase shifters. The electric downtilt angle adjustment apparatus provided in the present invention has the advantages of having a simple structure, being convenient to manufacture, low in cost, and light weight, having a small size, and having reliable quality.
