Patent ID: 11022217

Abstract:
A shift-type multi-phase-shifter drive transmission device includes a drive device (3), a shifting mechanism, multiple angle adjustment mechanisms and multiple ruler mechanisms. When the shift-type drive transmission device works, the drive device (3) firstly drives a shifting rack (11) of the shifting mechanism to move to a position which is corresponding to one of the angle adjustment mechanisms, a shifting bulge (111) on the shifting rack (11) is against a driving lever (13) for engaging an active clutch gear (16) with a passive clutch gear (17) of the corresponding angle adjustment mechanism, so as to further drive a transmission screw (19), thus a transmission nut (20) on the transmission screw (19) implements the reciprocating linear motion. The shift-type drive transmission device is able to drive multiple phase shifters through one drive device (3) to perform angle adjustment, which reduces an amount of the drive sources and effectively decreases cost.
