Abstract

The invention relates to a classroom model based on holographic laser projection and the application thereof. The classroom model comprises a main body bracket. A lower base plate, a quadrangular pyramid and an image source turntable are arranged on the main body bracket. The lower base plate is fixed at the lower part of the main body bracket, and the quadrangular pyramid is arranged above the lower base plate. The quadrangular pyramid is surrounded by four trapezoidal acrylic plates. The image source turntable is located directly above the quadrangular pyramid. A liquid crystal display screen is arranged in the image source turntable, and the top is connected with a driven sheave through a driving shaft. The driven sheave cooperates with a driving dial to form a sheave mechanism. The driving dial is connected with the output shaft of a motor through the driving shaft. The motor is fixed on the main body bracket through a motor mounting plate and a supporting column. The motor and the sheave mechanism drive the image source turntable to rotate, so that students can all-directionally watch holographic laser projection. The interactivity and the interestingness of classroom teaching are enhanced. Teaching contents are vivid and visual. Teaching quality can be improved.

Further, image source is described LCDs, to provide image sources.
Further, when described image source turntable rotates, described LCDs uses described slip ring to connect power supply to prevent coiling.
Further, the transmission of the described leading screw, described feed screw nut and the described bevel gear that are provided with by described lower shoe realizes institute State the folding of rectangular pyramid, thus save occupation of land space.
Further, the angle between trapezoidal acrylic board and the described lower shoe of described truncated rectangular pyramids is 45 °.
The invention have the benefit that
Screen image is thrown by a kind of based on line holographic projections technology classroom model and application that the present invention provides in 360 degree of panorama modes Being mapped on rectangular pyramid 3D holographic cell, make projection picture more third dimension, start motor, motor drives image by Geneva mechanism Source turntable rotates, and presents the line holographic projections bandwagon effect without viewing dead angle, and rectangular pyramid can be real by the transmission of leading screw and bevel gear Existing folding, thus save and take up room.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is lower shoe structural representation of the present invention;
