  • the second limiting rod 423 is provided so that the driving seat 422 can cooperate with the driving screw 421 to prevent rotation.
  • the form of the drive seat 422 is not limited, and it can be an integrated setting or a detachable setting.
  • the drive seat 422 is set to be detachable to facilitate the assembly and installation of parts. Since the second input part 41 drives the drive screw 421 to rotate in a single direction, in order to make the drive seat 422 reciprocate on the drive screw 421, the drive screw 421 can be set as a bidirectional screw, and the drive screw 421 can also be reversed by external parts under the premise of the unidirectional rotation of the first drive gear 325, which is not limited here.

  • the input shaft 6 in the second input part 41 can be driven to rotate, and the driving screw 421 can be driven to rotate through the seventh transmission gear 38, the eighth transmission gear 39 and the ninth transmission gear 40 to complete the adjustment of the horizontal position of the first output part 32;
  • the power output part 11 is connected to the first input part 31 by driving, the input shaft 6 in the first input part 31 can be driven to rotate, and the first output part 32 can be driven to connect through the mutual meshing relationship of the third transmission gear 34, the fourth transmission gear 35, the fifth transmission gear 36 and the sixth transmission gear 37, so that the first output part 32 drives the corresponding regulator assembly 2 to adjust the electrical downtilt angle of the target antenna.
  • the power transmission between the first input part 31 and the first output part 32 and the power transmission between the second input part 41 and the second output part 42 are respectively completed in the form of multiple sets of gear transmission, so that the overall layout of the transmission device 100 is more compact and the integration is higher.
  • the present application also proposes an antenna system, which includes the transmission device 100 as described above. Since the antenna system adopts all the technical solutions of all the above embodiments, it at least has the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
