Six-degree-of-freedom stable seats connected in parallel

Abstract

The invention discloses six-degree-of-freedom stable seats connected in parallel. Each seat comprises a seat body, handles, a base, and six driving branches and four spring load branches, wherein the driving branches and the spring load branches are used for connecting the seat body and the base; among the six driving branches, four SPSP driving branches adopting the same structures are arranged on two sides of the seat body, and two SPS driving branches adopting the same structures are arranged below the seat body; one end of each of the four driving branches arranged on the two sides of the seat body is connected with the outer side of the corresponding handle through one corresponding spherical hinge; the other ends of the four driving branches arranged on the two sides of the seat body are vertically mounted on the base; one end of each of the two driving branches arranged below the seat body is connected with the bottom of the seat body through one corresponding spherical hinge; the other ends of the two driving branches arranged below the seat body are connected with the rear side of the base through corresponding spherical hinges; the four spring load branches are SPS branches adopting the same structures; and the two ends of each spring load branch are respectively connected with the bottom of the seat body and the base through corresponding spherical hinges. The six-degree-of-freedom stable seat provided by the invention is simple and compact in structure, and has the advantages that the height of the seat body above the ground is effectively reduced, the bearing capability of the seat body is greatly improved in the presence of the spring load branches, and the stable vibration isolation effect is very good.

Description

technical field [0001] The invention relates to a stable seat, in particular to a six-degree-of-freedom parallel stable seat. Background technique [0002] When a ship is sailing at sea, due to the influence of sea waves and sea wind, it will produce six degrees of freedom motions of rolling, pitching, yaw, sway, surge and heave. Activity. At the same time, with the advancement of science and technology, the society is constantly developing, and people's requirements for the quality of life are also gradually improving. When traveling on a cruise ship, these movements can also cause dizziness or discomfort to the occupants. In view of the above problems, it is necessary to propose a stable seat that can isolate the motion of the hull. At present, a multi-degree-of-freedom seat is used as a vehicle driving simulator for simulation training of various vehicles including armored vehicles, but its size is too large, and the simulation effect is not ideal, so it is not suitabl...

Problems solved by technology

At present, a multi-degree-of-freedom seat is used as a vehicle driving simulator for simulation training of various vehicles including armored vehicles, but its size is too large, and the simulation effect is not ideal, so it is not suitable for isolating the movement of the hull

[0003] Patent CN201420108962.4 proposes an electric sports seat, including a seat surface, a base, three support rods connecting the seat surface and the base, and three electric cylinders, which can realize three-dimensional movement of the seat, but cannot completely eliminate the above-mentioned Effects o
