Embodiment Construction

[0034] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present application, and Not an exhaustive list of all embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0035] The core idea of ​​this solution is to use the telescopic mechanism to drive the array antenna to fold and extend, and at the same time, use the drive mechanism to drive the support device to rotate, so as to realize the rapid retraction of the array antenna and save manpower and time costs.

[0036] Such as figure 1 As shown, a folded array antenna device is used to install multiple radiation units 13 on t...

Abstract

An embodiment of the present application provides a support structure, including: a main beam and a telescopic mechanism; one side of the telescopic mechanism is connected to the main beam, and the telescopic mechanism can perform telescopic movement in a direction perpendicular to the main beam; the The telescopic mechanism is provided with a plurality of row skeletons parallel to the main beam for fixing the antenna. The present application also discloses a foldable array antenna device, which includes: the above-mentioned supporting structure arranged on the antenna tower body; a plurality of radiation units are arranged on the supporting structure; the supporting structure can be relatively The antenna tower body rotates horizontally. The technical solution described in this application has the characteristics of simple structure, fast unfolding and folding, and the same thickness and size of the antenna before and after folding.

Description

technical field [0001] The present application relates to the field of radar antenna structures, in particular to a support structure and a foldable large array antenna device including the support structure. Background technique [0002] The warning radar has high mobility requirements. The length and width of the antenna are generally more than 10 meters (length) × 5 meters (width). The folding scheme of the antenna is a key link that affects the mobility of the radar. [0003] The choice of the antenna folding scheme depends on the size of the antenna, the number of radiating elements, and the arrangement. For horizontally polarized array antennas, the existing folding scheme is to divide the antenna into four rigid sub-arrays, and then fold the sub-arrays. This solution can make the radar antenna vehicle meet the requirements of road transportation, but there is a problem of super height during railway transportation. [0004] In view of the above-mentioned problems exi...
