Abstract

The present invention provides a telescopic-arm-type antenna unfolding mechanism including a box-type telescopic arm, which is an overall skeleton of the telescopic-arm type-antenna unfolding mechanism and includes a plurality of mutually connected joint arms; a horizontally extending oil cylinder group disposed in the box-type telescopic arm and providing a linear driving force for the telescopic-arm-type antenna unfolding mechanism; and a pulley transmission device for realizing the unfolding and the folding of the box-type telescopic arm, and fixed in the box-type telescopic arm and disposed corresponding to the horizontally extending oil cylinder group; and a combination slide rail disposed outside the wall surface of the box-type telescopic arm, and provided with a square slider connected with the antenna frame and used for the synchronous unfolding of the antenna frame. The telescopic-arm-type antenna unfolding mechanism reduces the antenna erection time, simplifies the erectionstep, and improves the reliability of the antenna erection.

Description

technical field [0001] The invention relates to the technical field of antenna equipment, in particular to a telescopic arm type antenna deployment mechanism. Background technique [0002] With the development of technology and increasing demand, the requirements for high mobility of ground radar are getting higher and higher, and the retractable performance of the antenna array directly affects the high mobility of radar. At the same time, the development of large-caliber front radar has become a trend, which undoubtedly restricts the development of high maneuverability of radar. [0003] The current radar antenna is often erected by the antenna, rotated and folded through multiple actions to realize the erection of the radar antenna; this erection method directly leads to a long time for the antenna erection, complicated erection steps, and a decrease in reliability. [0004] In view of the above-mentioned defects, the creator of the present invention has finally obtained...
