specific Embodiment

[0024] see figure 1 , a spherical three-degree-of-freedom parallel mechanism 100 for an entertainment robot, comprising a triangular prism bracket 110 , a drive unit 120 and a moving platform 130 . Each surface of the triangular prism is provided with a mounting groove, a threaded hole and a limit groove for installing the drive unit 120 and limiting the range of motion of the drive unit 120, and the structure of each surface is consistent; the drive unit is composed of three drive units. Each unit is hinged with the moving platform through an arc connecting rod 1208. Each unit is independently controlled to form three degrees of freedom, so as to realize multiple posture changes and flexible movements of the entertainment robot joints.

[0025] Specifically in this example, this mechanism is a parallel mechanism, there is a strict geometric relationship between the connecting rods, and there is a strict transmission speed ratio between the gears, the expression of the kinema...

Abstract

The invention discloses an entertainment robot sphere three-freedom-degree parallel mechanism which comprises a triangular prism support, a drive unit and a movable platform. The drive unit comprises three drive branch mechanisms of the same structure on the triangular prism support. Each drive branch mechanism comprises a motor, a bearing base, a gear set and an arc-shaped rod, wherein the arc-shaped rod comprises a circular-arc oscillating bar and a circular-arc connection rod, the circular-arc oscillating bar is hinged to the circular-arc connection rod, and the circular-arc connection rod is hinged to the movable platform. The movable platform is provided with axial pressing buckles for conducting axial limiting on the arc-shaped connection rods. In the working process, the parallel mechanism is controlled by the three independent drive branch mechanisms, and the movable platform conducts three-freedom-degree sphere rotation around the same point, so that an entertainment robot can achieve more vivid actions similar to the waist and shoulder actions of human bodies.

Description

technical field [0001] The invention relates to an entertainment robot, in particular to an entertainment robot spherical three-degree-of-freedom parallel mechanism. Background technique [0002] Today's popular fourth-generation theme parks use a large number of entertainment robots to create various atmospheres, especially high-simulation robots, which can bring tourists novel, exciting and unforgettable play experiences, improve the quality and popularity of theme parks, and attract More tourists go to visit the amusement park. [0003] However, most of these simulated robots have relatively few single-joint degrees of freedom or adopt a series method when they have multiple degrees of freedom. With the development of the fourth-generation theme park, the requirements for high-simulation robots are getting higher and higher, and more realistic mechanisms for simulating human joint motions are needed. Contents of the invention [0004] The object of the present inventi...
