摘要： The present disclosure relates to a phase shifter assembly includes: a first phase shifter including a first through-hole; a second phase shifter including a second through-hole and disposed at a side of the first phase shifter; a first gear including a third through-hole and disposed at a side of the second phase shifter facing away from the first phase shifter, wherein the first through-hole, the second through-hole, and the third through-hole are aligned with each other in an assembled state; a rack configured to drive, through driving the first gear, the second phase shifter to move relative to the first phase shifter, to adjust an electrical tilt angle of an antenna corresponding to the phase shifter assembly; and a first reversing mechanism disposed between the first gear and the rack and engaged with the first gear and the rack, respectively, making a direction of a component of a linear velocity at an electrical contact between the first phase shifter and the second phase shifter in a moving direction of the rack opposite to the moving direction of the rack.

摘要： The present disclosure provides a transmission mechanism, wherein the transmission mechanism comprises a driving shaft; and a stopper assembly, the stopper assembly including: a base, a surface of the base forming a first thread; and a rotating component, the rotating component being positioned on the driving shaft and can rotate with the driving shaft, and the surface of the rotating component forms a second thread matching the first thread, wherein ,at least one of the base and the rotating component is configured with a stopper; when the driving shaft rotates, the rotating component rotates with the driving shaft and slides relative to the base through an engagement of the first thread and the second thread; when the stopper resists the base or the rotating component, a relative sliding between the base and the rotating component stops. Since the stop assembly uses fewer parts and the structural fit gap is correspondingly reduced, the initial phase shift position of the phase shifter can be calibrated more accurately using this stop assembly, thereby improving the adjustment efficiency of the phase shifter.
