Three degree of freedom electric dynamic chair

Abstract

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.

Description

technical field [0001] The invention relates to a three-degree-of-freedom electric dynamic seat. Under the excitation of a control signal, the dynamic seat can perform actions such as front and rear swing, left and right swing, up and down, and bumping synchronously with a 3D film and television picture. Background technique [0002] Dynamic seats are used in entertainment industries such as 4D cinemas and commercial game consoles. They can combine 3D film and television images and special effects to bring audiences into virtual sports scenes and give audiences an immersive and real experience. The three-degree-of-freedom dynamic seat is developed on the basis of the two-degree-of-freedom dynamic seat. Compared with the two-degree-of-freedom dynamic seat, the vertical translation movement is added. The three-degree-of-freedom dynamic seats commonly used in the market are mainly driven by hydraulic pressure or air pressure. On the one hand, oil and gas are easy to leak, causi...
