The invention discloses a three degree of freedom electric dynamic chair which is applied to entertainment venues such as a 4D (four-dimensional) cinema and a commercial
game machine. The three degree of freedom electric dynamic chair comprises a base, a chair connecting plate and three sets of electric lifting mechanisms, wherein the electric lifting mechanisms are arranged between the base and the chair connecting plate, one set of electric lifting mechanism is arranged on the middle of the front end of the base, each of the left side and the right side of the rear end of the base is provided with one set of electric lifting mechanism, the three sets of electric lifting mechanisms are arranged into a regular triangle, each electric lifting mechanism comprises a spherical hinge, a
servo electric cylinder and a revolute pair
assembly, the upper end of each electric lifting mechanism is connected with the chair connecting plate through the spherical hinge, and the lower end of electric lifting mechanism is connected with the base through the revolute pair
assembly. The two sets of electric lifting mechanisms do rotating movement in a horizontal plane and one set of electric lifting mechanism does translation movement in a vertical direction, thus the actions of front-back swinging, left-right swinging, up-ascending and down-descending, bumping and the like of the dynamic chair can be completed; and by combining with other external facilities such as a networking
control system, a 3D film and
television system, blowing and
smoke, the three degree of freedom electric dynamic chair can bring the immersive feeling for audiences, and has the characteristics of flexibility in movement, controllable speed and acceleration, strong
bearing capacity,
low noise and the like.
