Title:
GEAR-SHIFT-TYPE MULTI-PATH PHASE-SHIFTER DRIVE TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/137594
Kind Code:
A1
Abstract:
Provided is a gear-shift-type multi-path phase-shifter drive transmission device, comprising: a drive device (3), a gear shift mechanism, a plurality of angle-adjusting mechanisms, and a plurality of scale mechanisms. During use, the drive device (3) drives a gear-shift gear rack (11) of the gear shift mechanism to move to the position of a corresponding angle-adjusting mechanism; a gear shift projection (111) of the gear-shift gear rack (11) holds a lever (13), causing the active clutch gear (16) of the angle-adjusting mechanism to mesh with the passive clutch gear (17), thereby driving a transmission threaded rod (19) to rotate and causing a transmission nut (20) on the transmission threaded rod (19) to move linearly in a reciprocating manner. In the phase-shifter drive transmission device, one drive device (3) may be used to drive a plurality of phase shifters to adjust angles; thus the quantity of drive sources is reduced, costs are effectively decreased, and using such a drive transmission device allows for a simpler structure; modularized assembly is possible and maintenance and replacement are convenient, while the external appearance is also more aesthetically pleasing; the problem of tangled wires does not occur and performance is more reliable.
