Problems solved by technology

Most of the existing devices fix the display panel and realize the dynamic light and shadow effect by changing the lighting effect. The light and shadow conversion effect is limited, and it needs to be observed from different angles to achieve a better viewing effect, which cannot well demonstrate the principle of perspective.

Embodiment 1

[0035] Applying the present invention to a science and technology exhibition hall, placing it inside the glass cover or fixing it on the wall, is mainly used to enrich residents' common sense of three-dimensional geometry and physical optics, and to control the panel by adjusting the reciprocating speed or swing angle of the motor. The small prismatic reflective angle of the unit achieves a relatively novel viewing effect. Internal specific embodiments of the present invention are as follows:

[0036] Such as figure 1 , image 3 As shown, the new device includes a motor 1, a cam 2, a driven wheel 3, a fixed end 4, a spring 5, a guide sleeve 6, a guide rod 7, a fixed support 8, a bracket 9, a cam 10, a top 11, a display panel 12, Spring 13 and light source 14.

[0037] The cam 2 is coaxially connected with the motor 1, and the driven wheel 3 moves up and down with the rotation of the cam 2. The cam 2 must be coaxially connected with the motor 1, wherein the rotation speed o...

Embodiment 2

[0049] The present invention can also be applied to the teaching tools of three-dimensional geometry and physical optics in primary and secondary schools. Because of its simple structure, it can be made into a portable small model for teaching in the classroom. Because of its simple operation and obvious observation results, it is helpful Students quickly understand and absorb relevant knowledge, and the others are the same as in Embodiment 1.

Abstract

The invention discloses a cube sensing device based on light and shadow conversion. The cube sensing device comprises a display panel, a fixed structure, a driving structure and a light source; the display panel is a panel composed of an orthorhombic array with an outer surface spliced by diamond pieces; the fixed structure is used for installing the display panel, and the display panel is disposed on a display platform by the fixed structure; the driving structure is used to drive the display panel to move; and the light emitted by the light source is directed toward the display panel. The mechanical motion of the cube sensing device belongs to the reciprocating motion, and the display panel continuously displays different viewing effects due to the constantly changed light, the cube sensing device increases the interest, and can also carry out science teaching on optical physics knowledge to achieve the purpose of teaching and learning.

Description

technical field [0001] The invention relates to a popular science teaching device, in particular to a device for perceiving a cube structure by generating visual illusions through light and shadow conversion. Background technique [0002] Today's society pays more and more attention to popular science education for the public. Science and technology museums around the world are not only open to the public free of charge, but also continuously introduce various novel popular science devices, trying to use various vivid and interesting cases to let everyone feel the magic of physical phenomena and learn at the same time. Basic physics knowledge. Optical phenomena are both common and complex physical phenomena, especially the parallel perspective and angled perspective of three-dimensional images are still difficult for many people to understand. Therefore, it is necessary to provide a popular science teaching device, which can enable people to learn the principle of perspecti...
