Description

Technical Field

[0001] The utility model relates to the technical field of audio-visual entertainment facilities, in particular to a tunnel-shaped panoramic amusement facility, and in particular to a multi-screen naked-eye tunnel facility with adjustable screens. Background Art

[0002] Tunnel-shaped panoramic amusement facilities are a new type of entertainment that combines modern technology with traditional amusement projects. They mainly create an immersive experience through advanced display technology, light and shadow effects, sound design and interactive devices.

[0003] Tunnel-shaped panoramic amusement rides commonly utilize LED displays or holographic projection technology. LED displays, with their vibrant colors, high brightness, and wide viewing angles, can present a rich variety of visual and animation effects. Holographic projection technology, on the other hand, uses lasers and specialized optical materials to blend virtual images with the real environment, creating scenes with a strong sense of three-dimensionality and space. Through precise light and shadow variations and stereo sound effects, tunnel-shaped panoramic amusement rides can simulate the atmosphere of various scenes, such as the starry sky, the ocean, and the forest, making visitors feel as if they were immersed in a real environment. The changes in light, shadow, and sound not only enhance the visual and auditory experience, but also increase the overall sense of immersion.

[0004] While traditional tunnel-shaped panoramic amusement rides have achieved certain breakthroughs in display technology and audiovisual effects, their panoramic screens are fixed, which, to a certain extent, restricts the design capabilities of audiovisual designers. Because the screens are fixed, audiovisual designers are often constrained by physical space when designing scenes, unable to dynamically adjust scene content based on real-time visitor feedback or behavior. This can lead to visitors experiencing scenes that feel monotonous and lack freshness.

[0005] Furthermore, the fixed panoramic screen means that audiovisual designers must consider the physical limitations of the screen and the audience's viewing angle when creating the experience. This, to a certain extent, limits the designers' creativity and the diversity of the scene design. Furthermore, since it cannot be dynamically adjusted based on the actual experience of tourists, it is also difficult for designers to continuously optimize and improve the scene.

[0006] To this end, the utility model proposes a multi-screen naked-eye tunnel facility with adjustable screens. Utility Model Content

[0007] In view of this, the embodiments of the present invention hope to provide a multi-screen naked-eye tunnel facility with adjustable screens to solve or alleviate the technical problems existing in the prior art, namely how to improve traditional tunnel-shaped panoramic amusement facilities so that audio-visual designers have better hardware support for the design of audio-visual images, thereby improving their design ceiling. The technical solution of the present invention is achieved as follows:

[0008] A multi-screen naked eye tunnel facility with adjustable screens comprises: a tunnel-shaped outer frame 1, and the following components which are sequentially installed in the tunnel-shaped outer frame 1 from the outside to the inside:

[0009] A first linkage assembly 2 capable of annularly sliding along the interior of the tunnel-shaped outer frame 1;

[0010] A second linkage assembly 3 mounted on the first linkage assembly 2 and capable of universal angle adjustment;

[0011] A flexible annular screen 4 is installed on the second linkage component 3 and can be flexibly deformed according to the sliding position change of the first linkage component 2 and the universal angle change of the second linkage component 3.

[0012] During use, visitors can travel through the tunnel-shaped outer frame 1, or more precisely, through the flexible annular screen 4, achieving a panoramic audiovisual effect based on the audiovisual images transmitted by the flexible annular screen 4. Furthermore, based on the aforementioned hardware support, designers can tailor the audiovisual images based on the fact that some structures of the flexible annular screen 4 can be adjusted to a certain degree of angle and some structures can be adjusted to a certain degree of circular position, thereby achieving a more three-dimensional and realistic visual effect. In other words, this tunnel-shaped amusement facility with an adjustable screen essentially provides designers with a hardware platform, significantly raising the design ceiling for the audiovisual effects of traditional panoramic amusement facilities.

[0013] In one embodiment, the first linkage assembly 2 includes an annular guide rail 201 fixed to the inner wall of the tunnel-shaped outer frame 1, and at least four support units 202 arranged in an annular array in the tunnel-shaped outer frame 1;

[0014] The support unit 202 at the upper portion is fixed to the inner wall of the tunnel-shaped outer frame 1, and the support unit 202 at the lower portion is annularly slidably fitted in the annular guide rail 201;

[0015] The support unit 202 at the upper portion can control the support unit 202 at the lower portion to perform a certain degree of annular sliding.

[0016] In one embodiment, the support unit 202 includes an arc-shaped frame 2021; the arc-shaped frame 2021 of the support unit 202 located at the upper portion is fixed to the inner wall of the tunnel-shaped outer frame 1, and the arc-shaped frame 2021 of the support unit 202 located at the lower portion is annularly slidably fitted in the annular guide rail 201;

[0017] The curved frame 2021 of the upper support unit 202 is hingedly connected to the cylinder body of the first servo electric cylinder 2022 via a fisheye joint. The piston rod of the first servo electric cylinder 2022 is hingedly connected to the outer surface of the curved frame 2021 of the lower support unit 202 via a fisheye joint. In other words, extending or retracting the piston rod of the first servo electric cylinder 2022 controls the curved frame 2021 of the lower support unit 202 to annularly slide with the annular guide rail 201.

[0018] In one embodiment, the second linkage assembly 3 includes two fixing frames 301 and a second servo electric cylinder 302 arranged in a ring and connected between the two fixing frames 301.

[0019] The cylinder body and piston rod of the second servo electric cylinder 302 are universally hinged to the respective opposite sides of the two fixing frames 301 through a universal joint coupling 303;

[0020] One of the fixing frames 301 is fixed to the connecting frame 2023 of the arc frame 2021 of the supporting unit 202 of the first linkage assembly 2, and the other fixing frame 301 is fixed to the non-screen side of the flexible annular screen 4;

[0021] When each of the second servo electric cylinders 302 is in operation, it can control the other fixing frame 301 to perform universal angle adjustment, so that a part of the structure of the flexible annular screen 4 fixed at the "other fixing frame 301" undergoes a certain degree of deformation.

[0022] In one embodiment, three adjacent second servo cylinders 302 are arranged in an N-shape. In this way, when a second servo cylinder 302 reaches its limit travel point, the two adjacent second servo cylinders 302 can compensate for it.

[0023] In one embodiment, the present invention further comprises a platform 5 fixed in the tunnel-shaped outer frame 1 , and a sightseeing bus 6 for carrying tourists is provided on the platform 5 via rails.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] (1) Improved the upper limit and diversity of audio-visual design: By introducing the first linkage component and the second linkage component and utilizing the precise control capability of the servo electric cylinder, this technology enables audio-visual designers to more flexibly adjust the position and shape of the flexible ring screen. This not only increases the diversity of design, but also enables designers to create more unique and engaging audio-visual effects according to actual needs.

[0026] (2) Enhanced visitors’ sense of immersion and experience: Since the position and shape of the screen of the utility model can be adjusted to a certain extent, the amusement facility can present a more realistic and dynamic audio-visual picture. The realistic picture and dynamic effect significantly enhance the visitors’ sense of immersion and experience, allowing them to feel the fun brought by the amusement facility more deeply during the tour.

[0027] (3) Improved stability and reliability of amusement rides: This utility model, by adopting the universal joint function of the universal joint coupling, absorbs the stress and vibration caused by screen deformation to a certain extent, thereby improving the stability and reliability of the amusement ride. This improvement in stability and reliability not only extends the service life of the amusement ride, but also reduces maintenance requirements and lowers operating costs.

[0028] (4) Solving the problem of the stroke limitation of a single servo cylinder: The present invention solves the problem of the stroke limitation of a single servo cylinder by designing a second servo cylinder arranged in an N-shaped pattern. This design allows the two adjacent servo cylinders to compensate when one servo cylinder reaches its limit, thereby maintaining the continuity and stability of the flexible ring screen. This provides audio-visual designers with greater design space, allowing them to create more complex and continuous audio-visual effects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Example: See Figure 1-5 , this specific embodiment provides a multi-screen naked-eye tunnel facility with an adjustable screen, including: a tunnel-shaped outer frame 1, a first linkage component 2, a second linkage component 3 and a flexible annular screen 4. The tunnel-shaped outer frame 1 serves as the main structure and provides the basic form of the amusement facility. The first linkage component 2 is installed inside the tunnel-shaped outer frame 1 and is designed to slide in a ring to adjust the position of the screen. The second linkage component 3 is installed on the first linkage component 2 and has a universal angle adjustment function, so that the screen can be adjusted according to different angle requirements. The flexible annular screen 4 is installed on the second linkage component 3, and its characteristic is that it can flexibly deform according to the sliding position of the first linkage component 2 and the angle change of the second linkage component 3, thereby realizing dynamic adjustment of the screen.

[0038] Specifically: The design principle of this amusement facility is based on the combination of mechanical linkage and flexible screen technology. The first linkage component 2 is connected to the tunnel-shaped outer frame 1 through an annular sliding mechanism, allowing the screen to move in the horizontal direction. The second linkage component 3 achieves multi-angle adjustment through a universal joint or similar mechanical structure, increasing the flexibility of the screen in the vertical and tilt directions. The flexible annular screen 4 is made of flexible materials, such as a flexible LED display or a retractable projection screen, and can deform accordingly according to the position and angle changes of the mechanical linkage component below, maintaining the flatness of the screen and the continuity of the picture.

[0039] It is understood that, in the technical solution provided by this embodiment, from an application perspective, this amusement facility significantly enhances the audiovisual effects of traditional tunnel-shaped panoramic amusement facilities. Visitors can experience the panoramic audiovisual effects delivered by the flexible annular screen 4 as they navigate through the tunnel-shaped outer frame 1. Designers can leverage the angle and annular position adjustment capabilities of some of the screen's structures to tailor the audiovisual imagery, creating a more three-dimensional and realistic visual effect. This design not only enhances visitors' immersion but also provides designers with greater creative freedom, significantly raising the upper limit of audiovisual design for traditional panoramic amusement facilities.

[0040] It should be pointed out that the flexible ring screen 4 can be either a whole screen or a plurality of flexible screens spliced together in an approximately ring-shaped form; if it is the latter, the "flexible ring screen 4" as a whole should be called an "approximate topological shape", but it can be designed specifically according to the audio-visual images it plays to compensate for the visual impact brought by the topological shape.

[0041] In the technical solution of this embodiment, please refer to Figures 2 to 5 : The first linkage assembly 2 consists of a ring guide rail 201 and at least four support units 202. The ring guide rail 201 is fixed to the inner wall of the tunnel-shaped outer frame 1 to form an annular sliding track. The support units 202 are arranged in a ring array in the tunnel-shaped outer frame 1, wherein the support units 202 located at the upper part are fixedly mounted on the inner wall of the tunnel-shaped outer frame 1 to play a supporting and fixing role. The support units 202 located at the lower part are fitted on the ring guide rail 201 through an annular sliding, so that these support units can slide on the annular guide rail. In addition, the support units 202 located at the upper part also have a control function, which can control the support units 202 located at the lower part to perform a certain degree of annular sliding, thereby realizing dynamic adjustment of the screen position.

[0042] Specifically: Based on the interaction between the annular guide rail and the support unit. The annular guide rail 201 provides a stable sliding track to ensure that the support unit 202 can slide smoothly on it. The design of the support unit 202 enables it to not only play a supporting role, but also to adjust its position by sliding. The upper support unit 202 cooperates with the lower support unit 202 to transmit power to achieve the sliding of the lower support unit on the annular guide rail. This design enables the first linkage component 2 to flexibly adjust the position of the screen in the horizontal direction.

[0043] It can be understood that the technical solution provided in this embodiment significantly enhances the flexibility and dynamic effects of the tunnel-shaped amusement facility. By controlling the lower support unit 202 to slide on the annular guide rail 201, the designer can adjust the position of the flexible annular screen 4 in real time, thereby creating a more varied and dynamic audio-visual effect. This design not only enhances the immersion and experience of visitors, but also provides designers with greater creative freedom and design space. At the same time, due to the annular array arrangement and sliding fit design of the support unit 202, the stability and flatness of the screen during movement are ensured, further improving the overall quality of the amusement facility.

[0044] In this solution, all electrical components of the entire facility rely on AC power for energy supply; specifically, the electrical components of the entire facility are conventionally electrically connected to the AC power output port through facilities such as relays, transformers and button panels to meet the energy supply needs of all electrical components of the facility.

[0045] Specifically, a controller is also provided on the outside of the facility, which is used to connect and control all electrical components of the entire facility to be driven according to a pre-set program as a preset value and drive mode; it should be pointed out that the above-mentioned drive mode corresponds to the corresponding start and stop time intervals, speed, power and other output parameters between the relevant electrical components below, that is, it meets the requirements of the relevant electrical components described below to drive the relevant mechanical facilities to operate according to the functions described therein.

[0046] In the technical solution of this embodiment, please refer to Figures 2 to 5 The support unit 202 is mainly composed of an arc frame 2021 and a first servo electric cylinder 2022. The arc frame 2021 of the upper support unit 202 is fixedly mounted on the inner wall of the tunnel-shaped outer frame 1, providing a stable support. The arc frame 2021 of the lower support unit 202 is designed to slide in an annular manner on the annular guide rail 201, thereby achieving dynamic position adjustment. To achieve this function, the arc frame 2021 of the upper support unit 202 is hingedly connected to the cylinder body of the first servo electric cylinder 2022 via a fisheye joint, while the piston rod of the first servo electric cylinder 2022 is hingedly connected to the outer surface of the arc frame 2021 of the lower support unit 202 via another fisheye joint. In this way, when the piston rod of the first servo electric cylinder 2022 extends or retracts, the arc frame 2021 of the lower support unit 202 can be controlled to slide in an annular manner on the annular guide rail 201.

[0047] Specifically: Based on the telescopic movement of the servo electric cylinder and the articulated coordination of the fisheye joint. The first servo electric cylinder 2022 is an electric device that can accurately control the extension and retraction of the piston rod, and realizes the movement of the piston rod through its internal motor and transmission mechanism. The fisheye joint is a connector that allows relative rotation within a certain angle range. Its design allows the connected parts to perform a certain degree of relative movement while maintaining the connection. In this embodiment, the fisheye joint is used to connect the arc frame 2021 and the first servo electric cylinder 2022, so that when the piston rod of the servo electric cylinder moves, it can drive the lower arc frame 2021 to slide on the annular guide rail 201.

[0048] It is understandable that in the technical solution provided in this embodiment, the curved frame 2021 of the lower support unit 202 is precisely controlled by the first servo electric cylinder 2022 to achieve flexible sliding of the circular guide rail 201. This enables designers to more precisely adjust the position of the flexible annular screen 4, thereby creating a more refined and dynamic audio-visual effect. At the same time, due to the use of fisheye joints for articulation, the design can also absorb and alleviate the stress and vibration caused by the adjustment of the screen position to a certain extent, thereby improving the stability and reliability of the amusement facility. This design not only enhances the immersion and experience of tourists, but also provides a guarantee for the long-term stable operation of the amusement facility.

[0049] In the technical solution of this embodiment, please refer to Figures 2 to 5 : The second linkage assembly 3 consists of two fixed frames 301 and a second servo electric cylinder 302 arranged in a ring. The two fixed frames 301 are respectively used to connect the support unit 202 of the first linkage assembly 2 and the flexible annular screen 4. Specifically, one fixed frame 301 is fixed to the connecting frame 2023 of the arc frame 2021 of the support unit 202, while the other fixed frame 301 is fixed to the non-screen side of the flexible annular screen 4. The second servo electric cylinder 302 is arranged in a ring and connected between the two fixed frames 301. Its cylinder body and piston rod are universally hinged on the respective opposite sides of the two fixed frames 301 through a universal joint coupling 303. In this way, when each second servo electric cylinder 302 is executed, it can control the fixed frame 301 connected to it to perform universal angle adjustment, thereby causing the partial structure of the flexible annular screen 4 fixed at the fixed frame 301 to undergo a certain degree of deformation.

[0050] Specifically: Based on the telescopic movement of the servo electric cylinder and the universal articulation function of the universal joint coupling. The second servo electric cylinder 302 is an electric device that can accurately control the extension and retraction of the piston rod, and realizes the movement of the piston rod through its internal motor and transmission mechanism. The universal joint coupling 303 is a connecting part that can allow relative rotation in two mutually perpendicular planes. Its design enables the connecting parts to perform multi-directional relative movement while maintaining the connection. In this embodiment, the universal joint coupling 303 is used to connect the cylinder body and piston rod of the second servo electric cylinder 302 with the two fixed frames 301, so that when the piston rod of the servo electric cylinder moves, it can drive the fixed frame 301 connected to it to perform universal angle adjustment, thereby realizing the deformation of part of the structure of the flexible annular screen 4.

[0051] It is understandable that in the technical solution provided in this embodiment: through the precise control of the second servo electric cylinder 302 and the universal articulation function of the universal joint coupling 303, flexible deformation of part of the structure of the flexible annular screen 4 is achieved. This allows designers to more accurately adjust the shape and angle of the screen to meet different audio-visual effect requirements. At the same time, due to the use of a universal joint coupling for connection, the design can also absorb and alleviate the stress and vibration caused by the deformation of the screen to a certain extent, thereby improving the stability and reliability of the amusement facility. This design not only enhances the immersion and experience of tourists, but also provides strong hardware support for the diverse audio-visual effects of the amusement facility.

[0052] In the technical solution of this embodiment, please refer to Figures 2 to 5 Every three adjacent second servo cylinders 302 are designed to be arranged in an N-shape. This arrangement ensures that when one second servo cylinder 302 reaches its limit of travel, the two adjacent second servo cylinders 302 still have sufficient travel space to compensate, thereby maintaining the continuity and stability of the flexible annular screen 4.

[0053] Specifically, the design utilizes the coordinated operation of multiple servo cylinders and an N-shaped arrangement. By arranging every three adjacent second servo cylinders 302 in an N-shaped configuration, it ensures that at all times, at least two servo cylinders are in a non-limited travel state, providing additional travel to compensate for those at the limit. This design leverages the precise control capabilities and stroke adjustability of the servo cylinders, achieving a wider travel range and more stable screen deformation through the coordinated operation of multiple cylinders. This enhanced control capability enables audiovisual designers to more delicately adjust the shape and angle of the screen, resulting in a more realistic and engaging audiovisual experience.

[0054] It can be understood that in the technical solution provided by this embodiment, the N-shaped arrangement significantly improves the deformation capacity and stability of the flexible annular screen 4. This allows the screen to deform smoothly and continuously over a wider range, without the sudden changes or instability caused by a single servo cylinder reaching its limit. This design not only enhances the audiovisual effects of the amusement ride but also increases the visitor's sense of immersion and experience. Furthermore, because multiple servo cylinders can work together to compensate for each other's travel limitations, this design also extends the ride's service life and reduces maintenance requirements.

[0055] In the technical solution of this embodiment, please refer to Figure 1 : It also includes a platform 5 fixed in the tunnel-shaped outer frame 1, and the platform 5 is equipped with a sightseeing bus 6 for carrying tourists through rails.

[0056] Specifically, platform 5 is securely fastened to tunnel-shaped outer frame 1, providing a stable foundation for supporting the rails and tour bus 6. The rails, in turn, are laid on platform 5, creating a smooth and stable path for tour bus 6. Through the interaction of its wheels and rails, tour bus 6 can travel along a pre-set route on platform 5, guiding visitors throughout the entire tunnel-shaped amusement facility.

[0057] As can be appreciated, in the technical solution provided by this embodiment, guests can ride a tour bus 6 along a pre-set route within the tunnel-shaped outer frame 1 while enjoying the diverse audiovisual effects presented by the flexible annular screen 4. This design not only enhances the interactivity of the amusement facility but also allows visitors to more easily enjoy the entire experience. Furthermore, the robust design of the platform 5 and rails ensures the safety and stability of the tour bus 6, providing visitors with a safe and comfortable environment.

[0058] In summary, this specific embodiment addresses the issues associated with conventional technologies by employing the following technical means or features based on the aforementioned multi-panel naked-eye tunnel facility with adjustable screens: Conventional tunnel-shaped panoramic amusement rides lack a flexible screen adjustment mechanism. This embodiment, through the introduction of a first linkage assembly 2 (comprising an annular guide rail 201 and support unit 202) and a second linkage assembly 3, achieves a degree of control over the position and angle of the flexible annular screen 4. This allows audiovisual designers to flexibly adjust the screen's position and shape based on actual needs, thereby creating more diverse and dynamic audiovisual effects.

[0059] The above-described embodiments merely represent implementation methods for the relevant practical applications of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
