The hybrid drive movable multi-degree-of-freedom parallel motion platform comprises a first-layer folding mechanism, a second-layer rotating mechanism, a third-layer movable suction cup mechanism and a posture monitoring module; the first-layer folding mechanism comprises an upper top plate, a lower bottom plate, a folding frame and a linear driver; a folding frame is arranged between the upper top plate and the lower bottom plate; the second-layer rotating mechanism comprises a flange cover, an upper flange, a worm wheel, a worm, a worm wheel frame, a lower flange, a motor and a motor frame; the third layer of movable suction cup mechanism comprises a supporting plate, telescopic suction cup devices, a seat plate, universal wheel assemblies and a supporting rod; and the telescopic suction cup devices are further arranged on the two sides of the supporting rod, suction cups of the telescopic suction cup devices can freely shuttle on the seat plate, the universal wheel assemblies are further installed on the bottom face of the seat plate, and the posture monitoring module is further installed on the seat plate. The hybrid drive movable multi-degree-of-freedom parallel motion platform has the characteristics of compact structure, flexibility in adjustment, large moving range, simplicity and convenience in operation and good stability, and is suitable for multi-degree-of-freedom posture adjustment and motion control.

Description

technical field [0001] The invention relates to a parallel motion platform, in particular to a hybrid-driven mobile multi-degree-of-freedom parallel motion platform and a control method. Background technique [0002] Motion platforms are widely used in industrial production, entertainment and leisure, such as motion simulation, stability compensation, dynamic simulation, etc. Parallel mechanisms are widely used in motion due to their advantages of high stiffness, strong bearing capacity, and ease of trajectory planning and control. platform. [0003] At present, the multi-freedom motion platform has received extensive attention in the market. The multi-degree-of-freedom motion platform is composed of multiple electric cylinders, six upper and lower universal hinges and two upper and lower platforms. The lower platform is fixed on the foundation. With the help of the telescopic movement of multiple electric cylinders, the movement of the upper platform with multiple degrees ...

AI Technical Summary

Problems solved by technology

At present, the multi-degree-of-freedom motion platform has problems such as single driving mode and inability to move flexibly

Multi-degree-of-freedom motion platforms are divided into serial motion platforms and parallel motion platforms. The serial motion platforms have low motion efficiency but high operational stability, while the parallel motion platforms overcome the problem of low efficiency and can complete operations efficiently. However, there are still a series of problems such as unstable operation and insufficient degrees of freedom.

In the previous design of multi-degree-of-freedom motion platforms, the degree of freedom design is relatively limited, and there is a problem of single drive during operation. It can realize up-and-down motion and sideways motion, but lacks a large-scale motion mechanism, and cannot perform large-scale platform motion, and the platform fixed
