TRANSMISSION MECHANISM FOR BASE STATION ANTENNA

The present disclosure relates to a transmission mechanism for a base station antenna, including: a motor having an output shaft; a gear assembly including a first gear and a second gear meshed with each other, an output end of the output shaft connected to the first gear and driving the first gear to rotate; a screw, a first end thereof connected to the second gear and a second end thereof rotatably supported by a support element; a movable element mounted on the screw, fixedly connected to one end of a connecting rod and translating along an axial direction of the screw when the screw rotates, thereby driving the connecting rod to translate along the axial direction; and an anti-rotation element configured to cooperate with the movable element to prevent the movable element from rotating with the screw, where the motor and the screw are configured to be arranged parallel to each other on a same side of the gear assembly. The transmission mechanism of the present disclosure can have a smaller length, can provide greater axial force to the connecting rod, and/or can be assembled and disassembled more quickly.
