AI Technical Summary

Technical Problem

The signal board of the existing airborne blade antenna is susceptible to corrosion from the external environment when it does not extend beyond the diffusion reception area, and the spring-driven reset action is prone to plastic deformation, affecting its service life and normal function.

Method used

The adjustment mechanism, driven by a motor, uses components such as a lead screw, lifting seat, and connecting rod to extend and reposition the signal board, eliminating the single spring repositioning mode and ensuring that the signal board has sufficient space when extended and is sealed and protected after repositioning.

Benefits of technology

It improves the signal board's resistance to damage and service life, ensures the stability and effectiveness of the reset action, avoids the shaping problem caused by spring compression, and realizes the orderly adjustment and protection functions of the signal board.

Abstract

This invention relates to the field of aviation antenna technology, specifically to an airborne blade antenna, comprising a base and a motor. A housing is fixedly connected to the top of the base, and an adjustment mechanism is provided inside the housing. The adjustment mechanism includes two guide rods, two positioning rods, a lead screw, and a rack. A lifting seat is threaded onto the lead screw, and symmetrically arranged connecting rods are rotatably connected to the lifting seat. Positioning blocks are fixedly connected to the side walls of the lifting seat corresponding to the connecting rods. Signal plates are slidably connected to the guide rods, and transmission blocks are fixedly connected to the signal plates. The beneficial effects of this invention are: it eliminates the need for a spring to provide reset power, avoiding the problem of long-term compression of the spring causing plastic deformation and shape fixation, thus ensuring the stability and effectiveness of the reset action during long-term antenna use, improving the overall service life of the antenna, and also extending the service life of the signal plates.
