TRANSMISSION, SELECTION, AND SWITCHING DEVICE FOR ELECTRICAL TILT ANTENNA

WIPO Patent Application WO/2020/052181

A1

The present invention provides a transmission, selection, and switching device for an electrical tilt antenna, for connecting and driving multiple downtilt angle adjustment devices and for performing selection and switching on multiple downtilt angle devices, and comprising a transmission mechanism, a selection and switching mechanism, and driven mechanisms. The transmission mechanism comprises a group of multi-stage transmission gears. The selection mechanism is a clutch mechanism, and comprises a selection screw, a switching and selection part, clutch parts, and a clutch spring. Under the action of the switching and selection part, the selection mechanism causes the clutch part to be connected to a corresponding driven screw in the driven mechanism. The driven mechanisms respectively correspond to the clutch parts of the switching and selection mechanism, and the driven mechanism comprises a driven screw and a driven internally-threaded slider threadingly connected to the driven screw. An axial rotation movement of the driven screw can be converted into an axial translation movement of the driven internally-threaded slider, so as to drive the downtilt angle adjustment device to perform a translation movement.
