Rotary viewing platform of spherical screen cinema

Abstract

The invention relates to a rotating stand for mutual configuration of ball-screen cinema and ball screen, comprising support tower frame and bearing seat arranged on the support tower frame, where a rotating shaft is arranged in the bearing seat, one end of the rotating shaft is connected with a rotating platform through hinge seat, and the other end of the rotating shaft is connected with a turning driver through transmission rotating arm. And the invention uses the overturn of the rotating platform to transform the stand from horizontal position to the position closely vertical to the ground so as to make each watching position suspended in the air and located on the focal plane of the ball screen so that the visual angle can completely enter in the ball screen to achieve the optimum watching effect of ball screen; and the invention has features of simple structure, low making cost, stable and reliable operating performance, convenient to be seated, implementing watching effect of dynamic and simulated flight; a bell cover is arranged on the rotating platform to give the passengers feeling of mysterious atmosphere and large-screen switching in space.

Description

technical field [0001] The invention relates to a rotating viewing platform used for a spherical screen theater and a spherical screen. Background technique [0002] Dome theaters are increasingly respected by people because of their strong three-dimensional viewing, good visual effects, and realistic immersion. The spherical screen theater is mainly composed of two parts: a spherical screen and a viewing platform. Most of the existing viewing platforms use a fixed ground or slope (inclined) viewing mode. There is a large difference in the separation distance between the two, resulting in the difference in viewing angle distance, which cannot be on the focal plane of the spherical screen at the same time, which affects the viewing effect and quality. In order to achieve a better viewing effect in the dome screen theater, the viewing platform can be set to an orientation that is close to vertical to the ground, so that the audience positions on the viewing platform are all o...

Problems solved by technology

However, viewing the platform vertically will cause great inconvenience to the audience's seating

For this reason, there is a method of adopting a roller coaster to achieve this kind of vertical suspension in the air to watch a dome movie, but the mechanism of the roller coaster is complicated and the cost is expensive to realize.
