Description

Technical Field

[0001] This utility model relates to the field of LDE holographic fan technology, specifically a multi-angle display device for digital innovation achievements. Background Technology

[0002] In the field of digital innovation achievement display, holographic fans have been widely and deeply applied in various display scenarios due to their ability to present three-dimensional images based on the principle of visual persistence. The structural design of traditional holographic fans usually adopts the form of straight fan blades, and the fan blades are mostly connected to the central drive component only on one side.

[0003] From a viewing perspective, during the process of the straight fan blades rotating at high speed to form a holographic image, the inherent limitations of the straight shape of the fan blades themselves will be clearly felt by the audience when they are in different positions. Specifically, for the audience located outside a certain angle range on the side of the fan blades, the straight structure of the fan blades will block and interfere with the propagation of light and visual imaging, making it difficult for these audiences to obtain a complete and coherent holographic image experience, which greatly affects the audience coverage and overall viewing experience of the display effect.

[0004] From the perspective of structural stability, the straight blades of traditional holographic fans are only connected to the center on one side. This connection method causes the blades to be subjected to a large centrifugal force when the blades rotate at high speed. Under the continuous action of centrifugal force, the blades are prone to slight deformation or even vibration. The deformation or vibration of the blades will directly affect the imaging components such as the LED light array, causing instability in the position and light emission state of the imaging components. This will have an extremely adverse effect on the clarity and stability of the image, often resulting in problems such as image ghosting and blurring. It cannot meet the needs of scenarios with high requirements for display effects, such as high-end product launches and exhibitions of precision scientific and technological achievements. Utility Model Content

[0005] The purpose of this invention is to provide a multi-angle display device for digital innovation achievements, so as to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: including a fixed base and a mounting base disposed on one side of the fixed base, wherein a power supply coil is assembled on the side of the fixed base near the mounting base, and a power receiving coil is assembled on the side of the mounting base near the fixed base. The mounting base has a cross-shaped slot on the side away from the fixed base. Four straight beams are screwed into the cross-shaped slot. An arc-shaped beam is fixedly connected to the opposite ends of two straight beams. An LED light array is embedded between the arc-shaped beam and the straight beam. A rotating seat is slidably engaged with the surface of the fixed base. A connecting rod is fixedly connected to the surface of the rotating seat. The arc-shaped beam and the connecting rod are fixedly connected by bolts.

[0007] In a further embodiment, an annular limiting seat is fixedly connected to the side of the fixed seat near the mounting seat, and an annular limiting block that is slidably connected to the annular limiting seat is assembled on the side of the mounting seat near the fixed seat.

[0008] In a further embodiment, conductive connectors are symmetrically mounted on the side of the straight beam near the cross slot, and conductive sockets for use with the conductive connectors are provided inside the cross slot.

[0009] In a further embodiment, the mounting base is equipped with a main control board, and a microcontroller (MCU) is embedded in the side of the straight beam near the cross slot.

[0010] In a further embodiment, a drive motor is installed inside the fixed base, and the output end of the drive motor extends through to the outside of the fixed base and is fixedly connected to the mounting base. A heat dissipation hole is provided on the side of the fixed base away from the mounting base, and a dustproof mesh is installed inside the heat dissipation hole.

[0011] In a further embodiment, the side of the mounting base away from the mounting base is equipped with a power supply socket, a data transmission interface, and control buttons.

[0012] In a further embodiment, a fixing bracket is fixedly connected to the side of the fixing base away from the mounting base.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention changes the shape of the traditional straight blades of a holographic fan by adopting an arc-shaped beam design. When the device rotates at high speed to form an image, the arc-shaped light-emitting surface can evenly scatter light over a wider angle range, allowing viewers from different directions to receive a more complete and continuous image light. This effectively reduces the viewing angle limitations caused by the straight shape of the blades, greatly expands the effective viewing range of the audience, and enhances the holographic image viewing experience for viewers from multiple directions.

[0014] This invention uses a rotating base and connecting rod to fix one end of the arc-shaped beam a second time. This design can disperse the centrifugal force and other forces that the fan blades bear when rotating at high speed. Compared with the structure of traditional holographic fans where the fan blades are only connected to the center on one side, the secondary fixing structure of this invention enhances the overall structural stability of the fan blades and reduces the possibility of deformation or shaking of the fan blades during high-speed rotation. This ensures the stability of the position and light emission state of imaging components such as LED light arrays, helps to improve the clarity of imaging, and reduces the probability of image ghosting and blurring.

[0017] 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.

[0018] This embodiment discloses a multi-angle display device for digital innovation achievements, including a fixed base 1 and a mounting base 2 disposed on one side of the fixed base 1. A power supply coil 3 is mounted on the side of the fixed base 1 near the mounting base 2, and a power receiving coil 4 is mounted on the side of the mounting base 2 near the fixed base 1. An annular limiting seat 11 is fixedly connected to the side of the fixed base 1 near the mounting base 2, and an annular limiting block 12, slidably connected to the annular limiting seat 11, is mounted on the side of the mounting base 2 near the fixed base 1. Figure 1 , Figure 2 and Figure 4 As shown, the fixed base 1 is the basic support component of the entire device, used to support and fix other related components, providing a stable installation foundation for the device. The mounting base 2 is set on one side of the fixed base 1 and is the main component for mounting the fan blades. The power supply coil 3 is assembled on the side of the fixed base 1 near the mounting base 2, and the power receiving coil 4 is assembled on the side of the mounting base 2 near the fixed base 1. The two are arranged opposite each other and realize the power transmission from the fixed base 1 to the mounting base 2 through the principle of electromagnetic induction, so as to power the LED light array 8 and other components on the mounting base 2. The annular limiting seat 11 is fixedly connected to the side of the fixed base 1 near the mounting base 2, and the annular limiting block 12 is assembled on the side of the mounting base 2 near the fixed base 1. The annular limiting block 12 is slidably connected to the annular limiting seat 11. Their function is to limit and guide the rotation of the mounting base 2, ensuring that the mounting base 2 maintains a stable posture during rotation and preventing deviation, thereby improving the stability of the device's rotational imaging.

[0019] More specifically, the mounting base 2 has a cross-shaped slot 5 on the side away from the fixed base 1. Four equidistant straight beams 6 are screwed into the cross-shaped slot 5. An arc-shaped beam 7 is fixedly connected to the opposite ends of two straight beams 6. An LED light array 8 is embedded between the arc-shaped beam 7 and the straight beams 6. A rotating seat 9 is slidably engaged with the surface of the fixed base 1. A connecting rod 10 is fixedly connected to the surface of the rotating seat 9. The arc-shaped beam 7 and the connecting rod 10 are fixedly connected by bolts. Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the cross-shaped slot 5 is formed on the surface of the mounting base 2 away from the fixed base 1, and is distributed in a cross shape. Four straight beams 6 are fixed inside the cross-shaped slot 5 by bolts at equal intervals, forming a support structure extending from the center of the mounting base 2 to the surrounding areas. The end of each straight beam 6 away from the center of the mounting base 2 is fixedly connected to the arc beam 7. The four straight beams 6 are respectively connected to the four arc beams 7, which together form the main frame of the fan blade of the device. The LED light array 8 is embedded in the connection between the straight beams 6 and the arc beams 7 and on the surface, conforming to the contour distribution of the straight beams 6 and the arc beams 7 to form a complete light-emitting array, which is the core of the imaging. The core component, the rotating seat 9, is mounted on the surface of the fixed seat 1 via a sliding snap-fit, allowing it to rotate stably along the surface of the fixed seat 1. One end of the connecting rod 10 is fixedly connected to the surface of the rotating seat 9, and the other end is fixedly connected to the side of the arc beam 7 away from the straight beam 6 via bolts, providing secondary support between the fan blade frame and the fixed seat 1. The cross slot 5 provides precise installation positioning for the straight beam 6, ensuring that the four straight beams 6 are equidistantly distributed, avoiding dynamic imbalance during fan blade rotation due to misalignment of the straight beams 6. The screw connection ensures a firm connection between the straight beam 6 and the mounting seat 2, preventing the straight beam 6 from falling off during high-speed rotation, and providing a stable support frame for the subsequent installation of the arc beam 7 and LED light array. The arc beam 7 bears the support force of the straight beam 6, and its arc profile breaks the limitations of traditional straight fan blades, guiding the LEDs. The light emission direction of the LED array diffuses to a wider angle, while the arc structure disperses the centrifugal force during high-speed rotation, reducing the risk of blade deformation. It serves the dual purpose of optimizing the viewing angle and resisting structural damage. The embedded LED array 8 is distributed along the straight beam 6 and the arc beam 7. When it rotates at high speed driven by the mounting base 2, the LED beads change color and light on and off, forming a holographic image using the principle of persistence of vision. It fits the distribution of the straight beam 6 and the arc beam 7 to ensure the complete coverage of the light array and avoid gaps in the image. The rotating base 9 and the connecting rod 10 form an auxiliary support structure. Through the fixed connection with the arc beam 7, it provides additional tension and support for the blade frame. Traditional holographic fans rely only on a single point connection between the straight beam 6 and the mounting base 2, which can easily cause the blades to vibrate due to centrifugal force. This structure can disperse the force on the arc beam 7, reducing the deformation and vibration of the blades during high-speed rotation, thereby ensuring the clarity of the image formed by the LED array 8. At the same time, the sliding snap-fit ​​design of the rotating base 9 can adapt to the blade rotation trajectory and avoid the support structure interfering with the normal rotation of the blades.

[0020] Furthermore, conductive connectors 13 are symmetrically mounted on the side of the straight beam 6 near the cross slot 5. A conductive socket 14 for use with the conductive connector 13 is provided inside the cross slot 5. A main control board 15 is mounted inside the mounting base 1. A microcontroller MCU 16 is embedded on the side of the straight beam 6 near the cross slot 5. A power supply socket 19, a data transmission interface 20, and control buttons 21 are respectively mounted on the side of the mounting base 1 away from the mounting base 2. Figure 3 , Figure 5 , Figure 6and Figure 7 As shown, conductive connectors 13 are symmetrically assembled on the side of the straight beam 6 near the cross slot 5, and are electrically connected to the microcontroller MCU16 embedded in the straight beam 6. Conductive sockets 14 are located inside the cross slot 5, forming a circuit connection with the main control board 15 inside the mounting base 1. The two are precisely connected through the screw connection between the straight beam 6 and the cross slot 5 to form a circuit. The main control board 15 is assembled inside the mounting base 1, and establishes a signal and power transmission link with the microcontroller MCU16 on the straight beam 6 through the connection of the conductive sockets 14 and conductive connectors 13. The microcontroller MCU16 is embedded in the straight beam 6... The side of beam 6 closest to the cross slot 5 directly connects to the LED light array 8 on the straight beam 6 and the curved beam 7. The power supply socket 19, data transmission interface 20, and control button 21 are all mounted on the side of the fixed base 1 away from the mounting base 2. The power supply socket 19 supplies power to the entire device, the data transmission interface 20 is used to transmit image data from external devices, and the control button 21 is used for manual operation of the device. All three are electrically connected to the main control board 15 inside the fixed base 1. The conductive connector 13 and the conductive socket 14, acting as a bridge for power and signal transmission, form a detachable electrical connection. When the straight beam... When screwed into the cross-shaped slot 5, the conductive connector 13 is inserted into the conductive socket 14, enabling power transmission from the fixed base 1 to the straight beam 6 and the curved beam 7, supplying power to the LED light array 8 and the microcontroller MCU 16. It also transmits control signals between the main control board 15 and the microcontroller MCU 16, ensuring accurate issuance of imaging commands. The detachable design facilitates the installation, replacement, and maintenance of the straight beam 6. The main control board 15 is the central control unit of the device, receiving image data from the external data transmission interface 20 and generating synchronous control commands by combining the speed information of the drive motor 17. The electrical link sends signals to the microcontroller MCU16 on each straight beam 6. It also integrates the power distribution of the power supply socket 19 and the operation commands of the control button 21, such as adjusting the speed and switching the screen. As a sub-control unit, the microcontroller MCU16 receives the instructions from the main control board 15 and directly drives the LED light array 8 on the corresponding straight beam 6 and curved beam 7. It precisely controls the on / off state, color and brightness of the LED beads to ensure that the light emission timing of each LED bead matches the spatial position when rotating at high speed, forming a stable holographic image. Layered control can reduce the signal load of a single path and improve control accuracy.

[0021] Finally, a drive motor 17 is installed inside the mounting base 1. The output end of the drive motor 17 extends through to the outside of the mounting base 1 and is fixedly connected to the mounting base 2. A heat dissipation hole 18 is provided on the side of the mounting base 1 away from the mounting base 2, and a dustproof mesh is installed inside the heat dissipation hole 18. A fixing bracket 22 is fixedly connected to the side of the mounting base 1 away from the mounting base 2. Figure 1 Figure 6 and Figure 7As shown, the drive motor 17 provides rotational power and is the power source of the device. Through the fixed connection between the output end and the mounting base 2, the drive motor 17 drives the mounting base 2 and the straight beam 6, arc beam 7, LED light array 8 and other components on the mounting base 2 to rotate at high speed, providing the basic motion conditions for the visual persistence effect of holographic imaging. The speed stability of the motor directly affects the continuity of imaging. Its output torque needs to match the weight of the fan blade frame to ensure a smooth rotation process. The function of the heat dissipation hole 18 is to dissipate the heat generated inside the fixed base 1 through air circulation, so as to avoid the high temperature causing the performance of electronic components to degrade or shorten their lifespan. The fixed bracket 22 provides external installation support for the entire device. According to the needs of the display scene, the fixed base 1 can be stably installed in the target position through the bracket to ensure that the device will not shake or shift when rotating at high speed, thus indirectly ensuring the stability of imaging.

[0022] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
