Abstract

The invention discloses an eggshell seat device capable of passively resisting shaking and adjusting angles, and belongs to the field of industrial design and manufacturing of upper-layer facilities of ships. The invention solves the problems that the comfort of passengers is greatly reduced and even symptoms such as dizziness and nausea are caused because the seat is unstable due to the shaking of the ship body in the sailing process of the existing small and medium-sized cruise ship. The seat is connected with the rubber base through the angle adjusting assembly to achieve face angle adjustment of the seat, all-directional position adjustment is achieved by connecting a cross ball cage type rolling universal joint, sensing of shaking is achieved by arranging a force sensing mechanism, passive shaking resistance is achieved by arranging a hydraulic rod device between the corresponding hinged supports, and the safety of the seat is improved. And the seat is kept in a horizontal stable state. Passive anti-shaking and active adjustment of the facing angle of the seat can be achieved in the ship shaking environment, the riding experience of passengers is remarkably improved, discomfort caused by ship body shaking is effectively relieved, and therefore the economical efficiency and comfort of ship operation are enhanced.
