AI Technical Summary

⚠Technical Problem

Existing antenna systems suffer from uneven force and asynchronous displacement in multi-channel synchronous control, which makes it difficult to meet reliable driving requirements, especially in large-size, high-precision smart antennas.

⚗Method used

The single-axis driven phase-shifting transmission module is adopted. Through the transmission shaft and multiple power conversion components spaced along its axial direction, the rotational torque of the transmission shaft is synchronously transmitted to all power conversion components, so as to achieve strict synchronization and synchronization accuracy of multi-channel output.

🎯Benefits of technology

It significantly improves the consistency and synchronization accuracy of the multi-phase shifter, simplifies the layout and control logic of the antenna system, enhances the reliability and ease of maintenance of the system, and is suitable for high-consistency beamforming of large-scale array antennas.

Abstract

This invention provides a phase-shifting drive module and antenna. The phase-shifting drive module includes a drive shaft and multiple power conversion components spaced apart along the axial direction of the drive shaft. Each power conversion component includes a drive gear and an output rack. The drive gear is sleeved on the drive shaft and fixedly installed. The drive gear and the output rack are drively connected. The power conversion components convert the rotational motion of the drive shaft into the linear motion of the output rack. Each output rack drives the phase-shifting component of its corresponding phase shifter to move. Multiple output racks drive multiple phase shifters to perform phase shifting. The drive shaft synchronously drives all power conversion components distributed along its axial direction to move synchronously. Each power conversion component converts the rotational motion of the drive shaft into linear motion, driving its corresponding phase shifter to perform phase shifting operation synchronously, effectively ensuring the consistency of operation of multiple phase shifters over a long span.
