Description

Technical Field

[0001] This utility model relates to the field of holographic projection equipment technology, and in particular to a holographic projection mechanism for interactive star evolution. Background Technology

[0002] With the continuous development of astronomical science popularization and interactive displays in science museums, the public's demand for visualization and interactivity in stellar evolution is increasing. Stellar evolution involves multiple stages, from star birth and the main sequence to red giants and white dwarfs. Its long time span and large spatial scale make it difficult for traditional textual explanations or static models to intuitively present the details of evolution. Holographic projection technology, with its three-dimensional display characteristics, can vividly recreate the stellar evolution process, becoming a key device for enhancing interactive experiences and improving science popularization effects. It is being increasingly widely used in various science museums and educational institutions.

[0003] In current interactive stellar evolution demonstration scenarios, while existing holographic projection equipment can achieve basic 3D projection functions, two issues still urgently need optimization in practical use. Firstly, to switch between different stages of stellar evolution projection content, existing equipment often requires disassembling lens components, connecting external control devices for parameter adjustments, or manually rotating the internal transmission structure to complete channel switching. Due to the lack of integrated linkage transmission design, this process not only requires staff to possess certain professional operational skills but is also cumbersome and time-consuming, making it difficult to quickly adjust the projection content according to the real-time needs of the demonstration scenario, thus limiting the flexibility and smoothness of the interactive display. Secondly, considering the differences in spatial height in different venues and the viewing angle requirements of different audience groups (such as children and adults), while existing equipment has height adjustment capabilities, the adjustment process often only achieves a single lifting and lowering action, without simultaneously considering the upward shift of the equipment's center of gravity after height increase. Due to the lack of a support range extension structure linked to height adjustment, the bottom support stability is insufficient after the equipment is raised. To improve stability, additional external counterweights or supports are required, increasing the complexity of equipment use and making it difficult to balance the convenience of height adjustment with structural stability.

[0004] In response to this technical problem, this application proposes a holographic projection mechanism for interactive stellar evolution. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a holographic projection mechanism for interactive stellar evolution. This mechanism allows for rapid switching of projection channels via button linkage, eliminating the need for complex adjustments and enhancing display flexibility. The height adjustment simultaneously expands the support range, and the grounding components enhance stability, adapting to different scenario requirements while resolving the pain points of existing equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A holographic projection mechanism for interactive stellar evolution includes a projection glass and a projection device. The outer wall of the projection glass is fixedly connected to the upper side of the outer wall of the projection device. A speaker is fixedly connected to the front outer wall of the projection device. A base is slidably connected to the lower outer wall of the projection device. A support component is provided at the bottom of the projection device. A projection hole is fixedly connected to the upper outer wall of the projection device. A button is slidably connected to the upper side of the projection device. A replacement component is provided to the left of the button.

[0007] Furthermore, the replacement component includes a sliding ring fixedly connected to the inside of the back side of the button, a rotating disk is provided inside the sliding ring, and the outer wall of the rotating disk is rotatably connected to the inside of the upper side of the projection device.

[0008] Furthermore, the support assembly includes a first fixed frame fixedly connected to the bottom of the projection device, a second fixed frame fixedly connected to the front side of the first fixed frame, a support rod slidably connected inside the second fixed frame, a screw threadedly connected to one end of the support rod, and a rubber pad fixedly connected to the lower end of the screw.

[0009] Furthermore, the outer wall of the rotating disk is provided with an inclined groove, and a guide block is provided inside the inclined groove. The outer wall of the guide block is fixedly connected to the inside of the sliding ring.

[0010] Furthermore, a fixed ring is slidably connected to the lower outer wall of the sliding ring, the outer wall of the fixed ring is fixedly connected to the upper inner side of the projection device, a telescopic rod is fixedly connected to the inner wall of the fixed ring, a spring is sleeved on the outer wall of the telescopic rod, and the upper end of the telescopic rod is fixedly connected to the lower side of the sliding ring.

[0011] Furthermore, the second fixing frame is threaded with a bidirectional threaded rod in the middle, and a knob is fixedly connected to the front end of the bidirectional threaded rod. A connecting plate is threaded to the outer wall of the front side of the knob, and a support frame is rotatably connected to the right side of the connecting plate. The other end of the support frame is rotatably connected to the outer wall of the front side of the support rod.

[0012] Furthermore, a rotating block is slidably connected inside the first fixed frame, and the outer wall of the rotating block is threadedly connected to the outside of the bidirectional threaded rod.

[0013] Furthermore, a rotating plate is rotatably connected to the lower side of the bidirectional threaded rod, and a fixed plate is rotatably connected to the lower side of the rotating plate. The outer wall of the fixed plate is fixedly connected to the inner wall of the upper side of the base.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the mechanism triggers the linkage between the sliding component and the rotating component by a button, which transforms linear motion into precise circular motion, enabling rapid switching of the projection channel. After switching, it can be automatically reset with the help of elastic components. The whole process does not require disassembling the equipment or performing complex debugging. It is simple to operate and responds quickly, greatly reducing the difficulty of operation for staff. At the same time, it can adjust the projection content in real time according to the display scene, improving the flexibility and smoothness of the interactive display of stellar evolution.

[0015] 2. In this utility model, when it is necessary to adjust the projection height to suit the display environment or the audience's perspective, the relevant components can be driven to generate a displacement difference through a simple rotation operation, so as to achieve a smooth rise of the projection device. At the same time, the bottom support range will be expanded during the height adjustment process, and the adjustable grounding component will enhance the fit with the ground. This effectively solves the instability problem that may be caused by the center of gravity shifting upward after the device is raised. It not only meets the projection height requirements in diverse spatial scenarios, but also ensures the structural stability and safety of the device during use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a holographic projection mechanism for interactive stellar evolution, comprising a projection glass 1 and a projection device 2. The outer wall of the projection glass 1 is fixedly connected to the upper side of the outer wall of the projection device 2. A speaker 3 is fixedly connected to the front outer wall of the projection device 2. A base 6 is slidably connected to the lower outer wall of the projection device 2. A first fixing frame 17 is provided at the bottom of the projection device 2. A second fixing frame 20 is fixedly connected to the front of the first fixing frame 17. A support rod 7 is slidably connected inside the second fixing frame 20. A screw 8 is threadedly connected to one end of the support rod 7. A rubber pad 9 is fixedly connected to the lower end of the screw 8. A projection hole 10 is fixedly connected to the upper outer wall of the projection device 2. A button 4 is slidably connected to the upper side of the projection device 2. A sliding ring 15 is provided to the left of the button 4. A rotating disk 11 is provided inside the sliding ring 15. The outer wall of the rotating disk 11 is rotatably connected to the upper interior of the projection device 2.

[0020] Specifically, during use, the device allows for quick lens replacement to meet diverse needs. Pressing button 4 moves the sliding ring 15 downwards. Because a guide block 12 is fixed to the inner wall of the sliding ring 15, and this guide block 12 is located in a semi-circular groove on the side of the rotating disk 11, as the sliding ring 15 slides downwards, the guide block 12 moves along the groove on the side of the rotating disk 11, causing the rotating disk 11 to rotate half a circle, thus changing the inner projection channel. When the button is released, the spring 14 and the telescopic rod 13 push the sliding ring 15 upwards, and the guide block 12 moves upwards along the axial groove on the outer side of the rotating disk 11, allowing button 4 to return to its original position for repeated use. However, while the device can be raised during use, this raises the center of gravity, leading to instability. Rotating knob 5 causes the rotating blocks 22 on both sides to move outwards, and the rotating plate 18 to rotate, thereby creating a displacement difference and increasing the height. Furthermore, rotating knob 5 will drive the connecting plate 19 to move towards the center, thereby causing the support frames 21 on both sides to rotate outwards, thus increasing the width of the support rods 7 on both sides. By rotating screw 8, the rubber pad 9 can be brought closer to the ground, improving the overall stability.

[0021] Reference Figures 2-4The outer wall of the rotating disk 11 has an inclined groove, and a guide block 12 is set inside the inclined groove. The outer wall of the guide block 12 is fixedly connected to the inside of the sliding ring 15. A fixed ring 16 is slidably connected to the lower outer wall of the sliding ring 15. The outer wall of the fixed ring 16 is fixedly connected to the upper inside of the projection device 2. A telescopic rod 13 is fixedly connected to the inner wall of the fixed ring 16. A spring 14 is sleeved on the outer wall of the telescopic rod 13. The upper end of the telescopic rod 13 is fixedly connected to the lower side of the sliding ring 15. A two-way threaded rod 24 is threadedly connected to the middle of the second fixed frame 20. A knob 5 is fixedly connected to the front end of the two-way threaded rod 24. A connecting plate 19 is threadedly connected to the front outer wall of the knob 5. A support frame 21 is rotatably connected to the right side of the connecting plate 19. The other end of the support frame 21 is rotatably connected to the front outer wall of the support rod 7. A rotating block 22 is slidably connected inside the first fixed frame 17. The outer wall of the rotating block 22 is threadedly connected to the outside of the two-way threaded rod 24. A rotating plate 18 is rotatably connected to the lower side of the bidirectional threaded rod 24, and a fixed plate 23 is rotatably connected to the lower side of the rotating plate 18. The outer wall of the fixed plate 23 is fixedly connected to the upper inner wall of the base 6.

[0022] Specifically, the device is mainly used to demonstrate the process of stellar evolution to facilitate audience learning. The inclined groove on the outer wall of the rotating disk 11, in conjunction with the guide block 12, converts the linear motion of the sliding ring 15 into the circular motion of the rotating disk 11, allowing it to rotate precisely half a revolution and achieve rapid channel switching. The guide block 12 is fixed inside the sliding ring 15, connecting the two and ensuring synchronized movement to prevent misalignment. The fixing ring 16 on the lower side of the sliding ring 15 is fixed to the upper side of the projection device 2, limiting the trajectory of the sliding ring 15 and preventing lateral deviation. The telescopic rod 13 on the inner wall of the fixing ring 16 provides support for the sliding ring 15 to reset, and works with the outer wall spring 14 to achieve reset—when the button 4 is pressed, the spring 14 is compressed and stores force, and when released, the force is released to push the sliding ring 15 to reset. The telescopic rod 13 can also stably transmit elastic force to ensure smooth reset.

[0023] The bidirectional threaded rod 24 in the middle of the second fixed frame 20 is the core of the adjustment, which can drive the rotating block 22 and the connecting plate 19, and has the functions of adjusting height and support width. The knob 5 at its front end is easy to manually apply force, reducing the difficulty of operation. The connecting plate 19 in front of the knob 5 is connected to the support frame 21. Rotating the knob 5 provides the rotation power for the support frame 21. When the connecting plate 19 moves to the middle, the support frame 21 pushes the support rod 7 to unfold, expanding the support range and improving the stability of the device after it is raised. The rotating block 22 in the first fixed frame 17 is threadedly connected to the bidirectional threaded rod 24. It rotates and slides with the rotating block 22, driving the rotating plate 18. The rotating plate 18 is rotatably connected to the fixed plate 23. When the rotating block 22 moves outward, the rotating plate 18 rotates around the fixed plate 23 to generate a displacement difference, thereby raising the projection device 2. The fixed plate 23 is fixed to the base 6, providing a stable fulcrum for the rotating plate 18 and ensuring accurate height adjustment.

[0024] Working principle: When the operator presses button 4 on the upper side of the projection device 2, button 4 causes the associated sliding ring 15 to slide downwards along the inner wall of the fixed ring 16. At this time, the fixed ring 16 acts as a guide, ensuring that the sliding ring 15 always moves vertically and avoids lateral deviation. As the sliding ring 15 moves downwards, the guide block 12 fixed inside it slides synchronously along the inclined groove on the outer wall of the rotating disk 11. Due to the trajectory design of the inclined groove, the linear motion of the guide block 12 is converted into the circular motion of the rotating disk 11, causing the rotating disk 11 to rotate precisely half a revolution around its own axis. The rotation of the rotating disk 11 directly drives the switching of the projection channel on its inner side, meeting the display needs of projection content at different stages of stellar evolution. When the staff releases button 4, the spring 14 on the outer wall of the telescopic rod 13, which is fixed to the inner wall of the fixing ring 16, releases the elastic potential energy that was previously compressed and stored, pushing the telescopic rod 13 to extend upward. The upper end of the telescopic rod 13 then drives the sliding ring 15 to return to its initial position. At the same time, the guide block 12 resets along the trajectory of the outer wall of the rotating disk 11, and button 4 also returns to its initial state, preparing for the next projection channel switching operation. The whole process does not require complicated disassembly, realizing a fast and convenient switching of the projection channel.
