Modularized synchronous translation unfolding antenna mechanism without sliding joint

The invention relates to a modular synchronous translation unfolding antenna mechanism without a sliding joint, and belongs to the technical field of aerospace mechanisms. The supporting mechanism comprises a base, a driving module, a first panel, a second panel, a third panel, a fourth panel, a first main module, a connecting module and a second main module. All the components are directly connected through the rotating pairs, no sliding pair or gear pair exists, and expansion can be conveniently achieved by adding the connecting module and the main module. The invention aims to overcome the defects in the prior art and provides the single-degree-of-freedom modular synchronous translation unfolding supporting mechanism without a sliding pair, a gear pair and a spherical pair. 本发明涉及一种不含滑动关节的模块化同步平动展开天线机构，属于航空航天机构技术领域。该支撑机构包括基座、驱动模块、第一面板、第二面板、第三面板、第四面板、第一主模块、连接模块和第二主模块。本发明各部件之间通过转动副直接连接，无滑动副或齿轮副，并可通过添加连接模块和主模块方便实现拓展。本发明的目的是解决现有技术方案中的不足之处，提供一种不含滑动副，齿轮副和球副的单自由度模块化同步平动展开支撑机构。
