Description

Technical Field

[0001] This utility model relates to the field of science and education demonstration equipment technology, specifically to a polarized light interactive display device. Background Technology

[0002] The asymmetry between the direction of vibration and the direction of wave propagation is called polarization. As an electromagnetic wave, the propagation direction of light waves is closely related to the vibration directions of the electric and magnetic fields. Specifically, the propagation direction of light waves is perpendicular to both the electric field vibration vector (E) and the magnetic field vibration vector (H). Therefore, light waves are transverse waves, and due to the relative independence of their vibration direction from their propagation direction, light waves exhibit polarization characteristics. However, when natural light passes through specific optical elements, such as polarizers, the vibration direction of the light waves is restricted or adjusted, allowing them to vibrate only in a specific direction, thus becoming polarized light.

[0003] Current polarized light educational demonstration devices often use large LCD screens of 50 inches or more to display phenomena related to polarized light. Demonstrations typically involve placing a rotating windmill or similar dynamic object in front of the screen and using a fan or duct to move the object and demonstrate the effect of polarized light. However, the high cost of purchasing and maintaining large LCD screens, coupled with the continuous airflow and frequent vibrations of the ducts during demonstrations, can lead to aging, damage, or loosening of the duct materials, thus affecting the stable operation of the overall demonstration device.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0037] like Figures 1-13As shown, in one embodiment, a polarized light interactive display device includes: a support frame assembly 1, on which a polarized display component 2 and a touch interaction component 3 are detachably mounted, allowing viewers to experience and understand polarized light phenomena more intuitively and interactively.

[0038] The polarization display component 2 mainly consists of a rhombic polarizer 21, a backplate polarizer 22, a diffuser 23, a servo motor 24, and an LED strip 25, specifically designed to demonstrate phenomena related to polarized light. The combination of the rhombic polarizer 21 and the backplate polarizer 22 effectively demonstrates the polarization properties of light. When light passes through the polarizer, viewers can clearly see changes in light intensity, color shifts, or changes in direction, thus intuitively experiencing the effects of polarization. The diffuser 23 provides a uniform light source by scattering light, enhancing the visual effect. The servo motor 24 controls the angle of the polarizer or the direction of the polarized light, allowing viewers to observe the changes in light at different polarization angles in real time by rotating or adjusting the angle. The LED strip 25 provides a stable light source, ensuring consistent light intensity and brightness throughout the demonstration. Through precise design and operation, this component helps viewers understand the working principles and applications of polarized light.

[0039] Furthermore, the touch interaction component 3 consists of a guardrail 31 and a touch screen component 32, aiming to provide viewers with a more immersive interactive experience. The guardrail 31 serves a protective function, ensuring that viewers can maintain a safe distance when interacting with the display device, while not obstructing their view. The touch screen component 32 allows viewers to obtain more display information through touch operations, such as explanations, scientific principles, and practical applications of polarized light phenomena. Users can switch display content and even conduct simulation experiments through simple clicks or swipes, helping viewers better understand polarization phenomena.

[0040] In addition, the support frame assembly 1 is used to ensure the stability of the polarization display assembly 2 and the touch interaction assembly 3. The support frame includes a pre-embedded part 11, the bottom of which is directly fixed to the ground 4 to avoid instability or tilting of the equipment due to external interference. A support frame 27 is installed on the top of the pre-embedded part 11. The support frame 27 supports and fixes the polarization display assembly 2 and the touch interaction assembly 3 to ensure that all display equipment can be stably hung or installed in the correct position to avoid shaking or loosening.

[0041] Please continue reading. Figures 1-13In this embodiment, the guardrail 31 includes multiple sets of stainless steel rectangular tubes 311, and a protective net 312 is installed between the rectangular tubes 311 to effectively prevent the audience from touching the polarization display component 2 and protect the safety of the audience and exhibits. A heat dissipation plate 313 is installed on the top of the guardrail 31. The heat dissipation plate 313 is provided with heat dissipation holes, and a fan can be installed inside to dissipate heat from the touch screen component 32 above, so as to avoid the touch screen component 32 from overheating and ensure its stable operation.

[0042] Furthermore, the touch screen assembly 32 includes a touch screen cover 321, which is fixed to the top of the guardrail 31. Inside the touch screen cover 321, a touch screen 323 is installed via a touch screen pressure plate 322. When in use, users can click on the touch screen 323 to watch instructional videos and select demonstration shapes.

[0043] Please continue reading. Figures 1-13 In this embodiment, the back plate polarizer 22 is bonded to the diffuser plate 23, and the back plate polarizer 22 and the diffuser plate 23 are symmetrically provided with mounting holes to facilitate precise docking and stable installation of the components.

[0044] Furthermore, the rhomboid polarizer 21 is bonded to the rhomboid bracket, which is made of highly transparent acrylic material to ensure that the transmission of light is not affected, thereby ensuring the clarity and realism of the polarization demonstration effect. The rhomboid bracket is connected to the servo motor 24 through a coupling. The design of the coupling ensures the precise adjustment of the polarizer, and the polarization angle can be adjusted as needed to show different polarization effects. The servo motor 24 is symmetrically mounted on the support frame 27. The rotation angle range of the servo motor 24 is 0-180°, which has high-precision rotation control capability and can accurately adjust the angle of the polarizer to ensure that each step of the demonstration can be carried out according to the preset requirements.

[0045] Furthermore, the light strip 25 is mounted on the support frame 27 via the fixing plate 26, providing uniform illumination for the entire display device and ensuring that there is no strong flickering or shadows during the polarized light demonstration. The support frame 27 and the backdrop wall 5 are detachably connected, facilitating the installation, maintenance, and transportation of the equipment, as well as the replacement and adjustment of the backdrop, ensuring the flexibility of the exhibition or display space. To ensure the safety and durability of the components, a pressure frame 28 is installed on the outside of the diffuser plate 23. The pressure frame 28, through its embedded protective plate 29, forms a robust protective barrier, effectively preventing damage to key components such as the internal rhomboid polarizer 21 and the back plate polarizer 22 from external impacts or other accidents. The protective plate 29 is designed not only to provide high-strength protection but also to have a certain degree of pressure resistance and scratch resistance, ensuring the long-term stable use of the internal components.

[0046] Please continue reading. Figure 12In this embodiment, the computer host, touchscreen, and speaker are electrically connected to achieve collaborative operation. When the touchscreen senses a user's touch, the signal is transmitted to the computer host. Upon receiving the touchscreen's operation signal, the computer host automatically launches the corresponding demonstration program and begins playing a preset demonstration video. Simultaneously, the computer host transmits data to the driver board via a serial port server, sending control signals to the driver board. Upon receiving the signals, the driver board precisely controls the connected servo motor 24, instructing it to rotate, which in turn rotates the rhomboid polarizer 21, displaying different polarization effects.

[0047] Working principle: The light emitted by the LED strip 25, after passing through the diffuser plate 23, can evenly illuminate the back plate polarizer 22. The touchscreen has various preset graphics. Clicking on a graphic triggers a signal from the computer. According to a preset program, the computer sends a signal to the serial port server. The server sends signals to multiple driver boards, which control the servo motor 24 to move to a preset position. This position, via a coupling, drives the rhomboid polarizer 21 to rotate. Different positions of the rhomboid polarizer 21 produce different color effects. When the rhomboid polarizer 21 is in a horizontal position, perpendicular to the direction of the back plate polarizer 22, it appears black, and the area behind the polarizer is not visible. Arrays of polarizers of different colors can form specific patterns.

[0048] Through the above technical solution, the entire device of this application is easy to operate and allows for intuitive viewing of the demonstration effect, and can operate stably for a long time.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
