Description

Technical Field

[0001] The present invention belongs to the technical field of holographic stage equipment, and particularly relates to a holographic stage equipment with an automatically lifting holographic film. Background Art

[0002] Holographic stage equipment is a kind of stage equipment that uses holographic projection technology and related hardware devices to create virtual images and interactive scenes. These devices project holographic images or 3D visual effects onto a transparent medium or a specific stage surface, creating the effects of virtual objects or characters floating, moving, and transforming, enabling the audience to visually experience a surreal spatial and scene change. Holographic stage equipment usually includes high-precision projectors, transparent screens or films made of special materials, optical lenses, and a dynamic control system, capable of achieving various effects such as 360-degree rotation, transformation, floating, and lifting of the images.

[0003] In the existing holographic stage equipment, projectors are usually used in combination with holographic films to project and display virtual images. However, the lifting and angle adjustment of the existing holographic films and projectors lack an automated function, resulting in the inability to accurately position the holographic film in the used or unused state, which will cause the presentation of the holographic effect to be unclear, seriously affecting the presentation of the stage effect. Moreover, the projector cannot flexibly adjust the projection angle, affecting the visual effect of the display, having an impact on the accuracy and stability of the projection image, and also restricting the switching and performance capabilities of the projector between different stage effects.

[0004] Therefore, we provide a holographic stage equipment with an automatically lifting holographic film to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a holographic stage equipment with an automatically lifting holographic film, which solves the problem that the existing holographic stage equipment cannot automatically adjust the lifting of the holographic film and the angle of the projector through the cooperation of a switching component and a limiting component.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention relates to a holographic stage device with an automatically lifting holographic film, including a chassis. One side of the top of the chassis is fixedly connected with a support frame, and a projector is arranged on the other side of the top of the chassis. A switching component is arranged in the inner cavity of the chassis. The switching component includes a lead screw, the lead screw is movably connected to the inner cavity of the chassis, a sliding sleeve is threadedly connected to the surface of the lead screw, a dual-axis motor is fixedly connected to the inner cavity of the sliding sleeve, a driving rod is fixedly connected to the output end of the dual-axis motor, a driving bevel gear is fixedly connected to one end of the driving rod, a rotating rod is movably connected to one side of the inner cavity of the chassis, and a driven rod is movably connected to the other side of the inner cavity of the chassis. Limiting components are arranged on both sides of the inner cavity of the chassis. The limiting components include spring rods, the spring rods are fixedly connected to both sides of the inner cavity of the chassis, a limiting clamp is fixedly connected to the free end of the spring rod, an inclined block is fixedly connected to one side of the limiting clamp, and rollers are movably connected to both sides of the sliding sleeve.

[0008] The present invention is further provided that a turntable is fixedly connected to one side of the top of the chassis, a support rod is movably connected to the inner cavity of the turntable, one end of the support rod is fixedly connected to the bottom of the projector, and a transmission rod is fixedly connected to the bottom of the projector.

[0009] The present invention is further provided that a winding roller is movably connected to the inner top of the support frame, rotating shafts are fixedly connected to both ends of the winding roller, driving belt pulleys are fixedly connected to both sides of the surface of the rotating rod, a driven belt pulley is fixedly connected to the surface of the rotating shaft, and the driving belt pulley and the driven belt pulley are connected by a belt in a transmission manner.

[0010] The present invention is further provided that a worm gear is fixedly connected to the surface of the transmission rod, a worm is fixedly connected to the surface of the driven rod, and the worm is meshed with the worm gear.

[0011] The present invention is further provided that driven bevel gears are fixedly connected to the surfaces of the transmission rod and the rotating rod, and the driving bevel gear is meshed with the driven bevel gear.

[0012] The present invention is further provided that a support plate is fixedly connected to one side of the inner cavity of the chassis, and one end of the driven rod is rotatably connected to the inner top of the support plate through a movable shaft.

[0013] The present invention is further provided that a servo motor is fixedly connected to one side of the chassis, and the output end of the servo motor is fixedly connected to one end of the lead screw.

[0014] The present invention is further provided that a fixing plate is fixedly connected to one side of the inner cavity of the chassis, and one end of the lead screw is rotatably connected to the inner top of the fixing plate through a movable shaft.

[0015] The present invention is further provided that a film receiving opening is formed at the bottom of the support frame, and the film receiving opening is used for lifting the holographic film.

[0016] The present invention is further configured such that a limiting block is fixedly connected to one side of the bottom of the sliding sleeve, a limiting groove is formed in the inner bottom of the chassis, and the bottom of the limiting block is slidably connected to the inner cavity of the limiting groove.

[0017] The present invention has the following beneficial effects.

[0018] 1. Driven by the servo motor, the present invention can move the sliding sleeve, so that the driving bevel gear at the output end of the double-shaft motor meshes with the driven bevel gear on the surface of the rotating rod. Furthermore, the double-shaft motor drives the rotating rod to rotate. The rotation of the rotating rod is coordinated with the driving pulley and the driven pulley thereon to drive the rotating shaft to rotate. The rotation of the rotating shaft further drives the winding roller to rotate, thereby realizing the lifting operation of the holographic film. Through this collaborative work, the position of the holographic film can be accurately controlled, enabling it to automatically lift as needed.

[0019] 2. The present invention drives the sliding sleeve to move through the servo motor, and further realizes the meshing of the driving bevel gear at the other output end of the double-shaft motor and the driven bevel gear on the surface of the driven rod. Driven by the double-shaft motor, the worm installed on the surface of the driven rod will drive the worm wheel to rotate, thereby promoting the rotation of the transmission rod. The rotation of the transmission rod drives the projector to adjust its angle through the connecting mechanism at its top, enabling the automatic adjustment of the projector angle, thus meeting the changing requirements of the projection angle in different scenarios.

[0020] 3. Through the movement of the sliding sleeve, the present invention can make the driving bevel gear and the driven bevel gear mesh. During the movement of the sliding sleeve, the roller will exert an extrusion force on the inclined block, causing the free end of the spring rod to contract, and further releasing the limiting effect of the limiting clip on the free end of the spring rod on the surface of the rotating rod or the driven rod, enabling the rotating rod or the driven rod to rotate freely. At the same time, when the driving bevel gear and the driven bevel gear are separated, due to the elastic action of the spring rod itself, the limiting clip will re-limit the rotating rod or the driven rod, thereby preventing the unnecessary automatic rotation of the rotating rod or the driven rod.

[0021] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment 3

[0040] Please refer to Figure 1-8 , on the basis of Embodiment 1, a support plate 25 is fixedly connected to one side of the inner cavity of the chassis 1. The inner top of the support plate 25 is rotatably connected to one end of the driven rod 10 through a movable shaft. One side of the chassis 1 is fixedly connected to a servo motor 26. The output end of the servo motor 26 is fixedly connected to one end of the lead screw 4. One side of the inner cavity of the chassis 1 is fixedly connected to a fixing plate 27. The inner top of the fixing plate 27 is rotatably connected to one end of the lead screw 4 through a movable shaft. A film receiving opening 28 is provided at the bottom of the support frame 2. The film receiving opening 28 is used for lifting and lowering the holographic film. One side of the bottom of the sliding sleeve 5 is fixedly connected with a limiting block. A limiting groove is provided at the bottom of the inner part of the chassis 1. The bottom of the limiting block is slidably connected to the inner cavity of the limiting groove.

[0041] Specifically, the support plate 25 is used to support and limit the driven rod 10 without affecting the rotation of the driven rod 10. The fixing plate 27 is used to support and limit the lead screw 4 without affecting the rotation of the lead screw 4. The servo motor 26 is fixed on one side of the cross frame in the middle of the chassis 1 to facilitate driving the rotation of the lead screw 4. The film receiving opening 28 is provided at the bottom of the support frame 2. The holographic film extends to the outside of the support frame 2 through the inner cavity of the film receiving opening 28 to facilitate the winding and unwinding of the holographic film and achieve the effect of lifting and lowering. The limiting block and the limiting groove can support and limit the sliding sleeve 5.

[0042] The working principle of the present invention is as follows: When this holographic stage device with automatic lifting of the holographic film is needed and the holographic film needs to be automatically lifted and lowered, the servo motor 26 can be started through an external control device. The servo motor 26 operates to drive the rotation of the lead screw 4. The lead screw 4 drives the sliding sleeve 5 to move. The sliding sleeve 5 drives the dual-axis motor 6 to move. When the sliding sleeve 5 moves to a certain position, the roller 14 will contact the inclined block 13 and, as the sliding sleeve 5 moves, the roller 14 presses the inclined block 13, causing the free end of the spring rod 11 to contract, thereby releasing the limit on the rotating rod 9 by the limit clamp 12. At the same time, the movement of the sliding sleeve 5 causes the driving bevel gear 8 at one end of the driving rod 7 to mesh with the driven bevel gear 24.

[0043] Then, the biaxial motor 6 can be started through an external control device. When the biaxial motor 6 works, it drives the driving rod 7 to rotate. The driving rod 7 drives the driving bevel gear 8 to rotate. The driving bevel gear 8 drives the driven bevel gear 24 to rotate. The driven bevel gear 24 drives the rotating rod 9 to rotate. The rotating rod 9 drives the driving pulley 20 to rotate. The driving pulley 20 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the winding roller 18 to rotate. The rotation of the winding roller 18 can wind and unwind the holographic film, thereby achieving the effect of automatic lifting.

[0044] When the angle of the projector 3 needs to be adjusted, only need to move the sliding sleeve 5 in the reverse direction. The movement of the sliding sleeve 5 causes the roller 14 to release the extrusion on the inclined block 13. The spring rod 11 returns to its original position by its own elasticity, driving the limiting clip 12 to limit the surface of the rotating rod 9, preventing the rotating rod 9 from rotating automatically. And the movement of the sliding sleeve 5 causes the driving bevel gear 8 to mesh with the driven bevel gear 24 on the surface of the driven rod 10. Driven by the biaxial motor 6, the driven rod 10 can drive the worm 23 to rotate. The worm 23 drives the worm wheel 22 to rotate. The worm wheel 22 drives the transmission rod 17 to rotate. The transmission rod 17 drives the projector 3 to rotate the angle. In this way, the automatic lifting of the holographic film and the automatic angle adjustment of the projector 3 can be completed.
