Document Type and Number:
WIPO Patent Application WO/2023/040229
Kind Code:
A1
Abstract:
A rotary motion system. The rotary motion system comprises an angle rotation joint having a single-degree-of-freedom. The angle rotation joint is composed of four members which are stacked on each other; a first member (6) is used as a basis and does not rotate, a second member (7) is located on the first member (6) and rotates around a first rotation axis (23), a third member (8) is located at the top of the second member (7) and rotates around a second rotation axis (24), and a fourth member (9) is located at the top of the third member (8); the second member (7) and the third member (8) have the same included angle at both ends, and are driven by a single motor and a transmission assembly and reversely rotate at equal angular velocity, and the fourth member (9) is limited not to rotate along with the third member (8); an additional motor is provided on the first member (6) and/or the fourth member (9), or a plurality of single-degree-of-freedom angle rotation joints are stacked to obtain a motion system having multiple degrees of freedom. The motion system can be applied to industrial fields such as virtual reality seats, medical instrument support systems, and solar trackers.
