The invention discloses a novel single-degree-of-freedom planar deployable mechanism network composed of three symmetric Bricard mechanisms, which is formed by connecting a plurality of three symmetric Bricard mechanisms through shear fork mechanisms, the three symmetric Bricard mechanisms in the mechanism network are divided into two types according to different rod lengths, and except for different rod length parameters, other parameters of the mechanisms are the same. According to the invention, the configuration characteristics of the three symmetric Bricard mechanisms are utilized, the constructed planar expandable mechanism network has the degree of freedom of 1 and is planar in an expanded state, and as the rod lengths of the units in the mechanism network are different, the mechanism network has smaller height and higher folding ratio in a folded state, and gridding expansion can be realized by adding new mechanism units; and the mechanism network is suitable for constructing alarge-scale space deployable mechanism.

    本发明公开一种由三对称Bricard机构组成的新型单自由度平面可展开机构网络,它由多个三对称Bricard机构通过剪叉机构连接而成,机构网络中的三对称Bricard机构按照杆长的不同分为两类,除杆长参数不同外,机构的其它参数都相同。本发明利用了三对称Bricard机构的构型特点,构造的平面可展开机构网络自由度为1,展开状态下为平面,因为机构网络中单元的杆长不同,在收拢状态下具有较小的高度,折叠比较高,可以通过增加新的机构单元实现网格化扩展,适合构建大尺度空间可展开机构。
