Abstract

The invention discloses a six-freedom-degree motion platform and electronic equipment. The six-freedom-degree motion platform comprises a fixed platform, a movable platform and three branched chain assemblies. Each branched chain assembly comprises a rotating drive device, a rotating connection piece and an automatic extending and retracting device, wherein the rotating drive device is designed tobe used for driving the rotating connection piece to rotate, the rotating connection piece is rotationally connected with the fixed platform, and the end, in the extending and retracting direction, of the automatic extending and retracting device is hinged to the rotating connection piece, and the other end of the automatic extending and retracting device is connected with the movable platform through a spherical hinge. Connection lines of the three rotating connection pieces form a triangle, and connection lines of three hinged points form a triangle. The six-freedom-degree motion platform is simple in structure and can achieve all kinds of motion in the space.

Description

technical field [0001] The present invention relates to the technical field of motion platforms, and more specifically, to a six-degree-of-freedom motion platform and electronic equipment. Background technique [0002] In recent years, parallel six-degree-of-freedom platforms have been widely used, such as motion simulators, parallel machine tools, aircraft wind tunnel tests, VR experience chairs, etc. The parallel platform has many advantages such as high rigidity, strong bearing capacity, high precision, and compact structure. [0003] The most common by far is the Stewart platform driven by six telescopic cylinders and used as a branch chain. The six-branch mechanism of the traditional Stewart platform has a large volume and mass, a small working stroke, and poor flexibility. Due to the interconnection and coupling between the branch chains, there are relatively many singular configurations, and the kinematic forward solution is complex, which is rarely found effectively...
