Document Type and Number:
WIPO Patent Application WO/2021/179210
Kind Code:
A1
Abstract:
A multi-degree-of-freedom parallel mechanism and an assembly provided with the parallel mechanism. The parallel mechanism comprises a guide piece (G), two primary branches (1) and one secondary branch (2); each primary branch (1) comprises two active pieces (11), one branch platform (12) and a plurality of primary connecting rods, the active pieces (11) being capable of moving back and forth along the guide piece (G); the secondary branch (2) comprises one positioning platform (20) and a plurality of secondary connecting rods; one of the two active pieces (11) in each primary branch (1) is connected to the branch platform (12) via at least two primary connecting rods to form a parallelogram which is parallel with a first plane (xoz); one of the two branch platforms (12) is connected to the positioning platform (20) in the secondary branch (2) via at least two secondary connecting rods to form a parallelogram which is capable of moving within a second plane (xoy); the first plane (xoz) is perpendicular to the second plane (xoy). The multi-degree-of-freedom parallel mechanism is compact and simple in structure and easy to control, and has a large range of movement on the vertical direction.
