AI Technical Summary
Technical Problem
The transmission methods of the current antenna industry's drive system restrict the antenna structure layout, the increase in the number of screws affects the width, the use of non-recyclable materials, and the long switching time.
Method used
A flexible transmission device is adopted, including a support base, output shaft, active component, flexible component and driven component. The transmission is achieved by switching gears and elastic elements, which reduces the space occupied inside the antenna and uses environmentally friendly materials.
Benefits of technology
It reduces the space occupied by the internal cavity of the antenna, the transmission stroke is not limited by the phase shifter stroke, saves switching time, and the materials are environmentally friendly.

Abstract
This application provides a flexible transmission device and apparatus, belonging to the field of electrically tunable antenna technology. The flexible transmission device includes a support base, a first output shaft, a second output shaft, an active component, a flexible component, and a driven component. The active component is located inside the support base, while the first and second output shafts are located outside the support base and are respectively connected to the active component. One end of the flexible component is connected to the active component, and the other end is connected to the driven component. The active component includes at least two switching gears and several driving wheels. The first output shaft drives one of the switching gears to slide and mesh with one of the driving wheels, while another switching gear is offset from the remaining driving wheels. The second output shaft drives the engaged driving wheel to rotate, thereby moving the flexible component and the driven component. By replacing the screw-slider structure with a flexible transmission device, less internal antenna cavity is occupied, saving space for antenna electrical design, and the transmission stroke is almost unrestricted by the phase shifter stroke.
