Single-degree-of-freedom three-spherical-surface four-rod loopback mechanism
The invention relates to a single-degree-of-freedom three-spherical-surface four-rod loopback mechanism which comprises three spherical-surface four-rod units, namely a first spherical-surface four-rod unit, a second spherical-surface four-rod unit and a third spherical-surface four-rod unit. Each spherical four-rod unit comprises four rod pieces, the four rod pieces are sequentially connected end to end, and the joints are rotationally connected; a connecting joint is arranged between two adjacent rod pieces; the first spherical four-bar unit is connected with one connecting joint of the second spherical four-bar unit and one connecting joint of the third spherical four-bar unit through two connecting joints of the first spherical four-bar unit and achieves rotating connection, and the other connecting joint of the second spherical four-bar unit is connected with the other connecting joint of the third spherical four-bar unit and achieves rotating connection. According to the single-degree-of-freedom three-spherical-surface four-rod loopback mechanism, the mechanism not only has the characteristic of single degree of freedom, but also has the characteristics that the mechanism is unfolded into a plane and folded into an umbrella-shaped bunch, and has reciprocating folding and unfolding movement and the like.
本发明涉及一种单自由度三球面四杆回环机构，包括三个球面四杆单元：第一球面四杆单元、第二球面四杆单元和第三球面四杆单元；每个球面四杆单元包括四个杆件，四个杆件依次首尾相接，且相接处为转动连接；在其中两个相邻的杆件中部设有连接关节；第一球面四杆单元通过自身的两个连接关节分别与第二球面四杆单元和第三球面四杆单元的一个连接关节相连并实现转动连接，第二球面四杆单元的另一个连接关节和第三球面四杆单元的另一个连接关节相连并实现转动连接。本发明提出一种单自由度三球面四杆回环机构，使机构不仅具有单自由度的特性、还具有展开为一个平面、折叠为伞状的一束、具有往复折展运动等特点。
