Description

Technical Field

[0001] The utility model relates to the technical field of holographic display cabinets, in particular to a holographic display cabinet for visual communication. Background Art

[0002] Holographic display cabinets are a new type of display technology that has emerged internationally in recent years. This technology can make three-dimensional images float directly in the free space outside the equipment without the help of any screen or medium, and the three-dimensional images are displayed from any 360° angle. This display method breaks the conventional physical display method. The clarity and color of the three-dimensional images are high and the three-dimensional sense is strong, so they are very realistic. They can give the audience a novel and mysterious visual impact, stimulate the audience's desire to explore, and can play a role in gathering popularity on the scene, deepening the visitor's impression, and increasing the popularity of the exhibits. At present, the appearance of the holographic display cabinet is composed of a cabinet body, a four-sided cone and a top plate from bottom to top. Four video playback devices corresponding to the four outer inclined surfaces of the four-sided cone are installed on the upper surface of the cabinet body or the lower surface of the top plate. The video playback device is specifically composed of an LCD screen, and the four-sided cone is specifically composed of holographic glass.

[0003] The holographic display cabinet is based on the principle that holographic glass forms a four-sided cone imaging. Through special processing of constructing a three-dimensional model of the product through actual shooting, the photographed product image or the product three-dimensional model image is superimposed into the scene through the light emitted by four LCD screens, forming a product display system that combines dynamic and static. People do not need to wear any polarized glasses and can enjoy the 3D phantom stereoscopic display effects without any constraints, giving people a visual impact and a strong sense of depth, so that the products can be better visually conveyed. However, in the existing holographic display cabinet, that is, the periphery of the four-sided cone, that is, the periphery of the 3D holographic image space, there is no device for blocking dust. The floating dust in the air may fall or be adsorbed on the outer wall of the LCD screen and the holographic glass. The dust accumulated on the outer wall of the LCD screen and the holographic glass will affect the light emitted by the LCD screen. In view of this, this paper aims to propose a holographic display cabinet that encloses and protects the 3D holographic image space and is used for visual communication. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the periphery of the holographic display cabinet, i.e., the four-sided pyramid, is not provided with a device for shielding dust, and floating dust in the air may accumulate on the outer wall of the liquid crystal screen and the holographic glass, thereby affecting the light emitted by the liquid crystal screen. A holographic display cabinet for visual communication is proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] A holographic display cabinet for visual communication includes a cabinet body and a top plate, both of which have square cross-sections. The top plate is arranged parallel to and directly above the cabinet body. A 3D stereoscopic holographic image space for visual communication of commodities is reserved between the cabinet body and the top plate. The cabinet body is provided with a dustproof mechanism, which includes a plurality of rubber rollers and a high-definition soft film ring arranged parallel to each other. The inner ring of the high-definition soft film ring is surrounded by a plurality of rubber rollers and is installed on the periphery of the 3D stereoscopic holographic image space.

[0007] Preferably, the lower ends of several rubber rollers are respectively vertically installed at the four corners of the cabinet table, the top ends of the rubber rollers are vertically connected to the top plate, and the rubber rollers are rotatably connected to the cabinet and the top plate respectively.

[0008] Preferably, belt loops are fixedly connected to the opening edges at the upper and lower ends of the high-definition soft film ring, and the two belt loops are in contact with the cabinet body and the top plate respectively. Annular belt grooves are provided on the outer periphery of the upper and lower ends of the rubber roller, and the inner cavity of the annular belt groove and the inner ring of the belt loop are extruded and engaged.

[0009] Preferably, one side of the high-definition soft film ring is rotatably connected to a rotating drum through several steering rollers, the outer wall of the rotating drum and the inner ring of the high-definition soft film ring are in contact with each other, and the upper and lower ends of the rotating drum are rotatably connected to the cabinet and the top plate through connecting plates respectively.

[0010] Preferably, an outer cylinder is fixedly mounted between the two connecting plates, a cleaning cloth is fixedly mounted on the inner wall of the outer cylinder, and the cleaning cloth and the high-definition soft film ring on the periphery of the outer cylinder are in contact with each other.

[0011] Preferably, a handwheel is coaxially fixedly connected to the lower end of the rotating drum.

[0012] Compared with the prior art, the present invention provides a holographic display cabinet for visual communication, which has the following beneficial effects:

[0013] 1. The holographic display cabinet for visual communication, by integrating the high-definition soft film ring in the dustproof mechanism with the cabinet body and the top plate, encloses the 3D holographic imaging space in the holographic display cabinet for visual communication, thereby effectively preventing dust from falling in the 3D holographic imaging space. This also prevents dust from falling on the four LCD screens and the outer surface of the holographic glass in the 3D holographic imaging space, ensuring that the light emitted by the LCD screen will not be blocked by dust.

[0014] 2. The holographic display cabinet used for visual communication can clean the outer surface of the high-definition soft film ring by rotating the rotating drum with a hand wheel. After the rotating drum rotates, the rotating drum can drive the high-definition soft film ring through two belt loops to rotate along eight rubber rollers around the periphery of the 3D holographic image space. The outer wall of the rotating high-definition soft film ring will pass through the cleaning cloth on the inner ring of the outer drum in turn, that is, the cleaning cloth will wipe the outer wall of the high-definition soft film ring in turn to ensure the cleanliness of the outer wall of the high-definition soft film ring.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] Refer to the attached Figure 1-4A holographic display cabinet for visual communication includes a cabinet body 1 and a top plate 2. The cross-sections of the cabinet body 1 and the top plate 2 are both square. The top plate 2 is fixedly installed parallel to and directly above the upper end table of the cabinet body 1. A 3D stereoscopic holographic image space for visual communication of goods is reserved between the cabinet body 1 and the top plate 2. A dustproof mechanism 3 is installed on the periphery of the 3D stereoscopic holographic image space.

[0023] In this embodiment, the dustproof mechanism 3 includes eight vertically parallel rubber rollers 301, a high-definition soft film ring 302, an outer cylinder 303, two vertically parallel steering rollers 308, a vertically arranged rotating drum 309 and a cleaning cloth 310. The lower ends of the rubber rollers 301, the steering rollers 308 and the rotating drum 309 are all vertically arranged on the same horizontal plane. The eight rubber rollers 301 are evenly divided into four groups and are respectively arranged at the four corners of the upper end table of the cabinet 1. The upper and lower ends of the rubber rollers 301 are respectively connected to the top plate 2 and the cabinet 1 for vertical rotation.

[0024] The high-definition soft film ring 302 is composed of a rectangular soft film connected end to end to form a ring. The inner ring of the high-definition soft film ring 302 surrounds the outer periphery of eight rubber rollers 301. Two steering rollers 308 are respectively arranged on the outside of two rubber rollers 301 at a corner of the cabinet 1. The steering rollers 308 and the adjacent rubber rollers 301 squeeze the outer and inner rings of the high-definition soft film ring 302. The two steering rollers 308 are mainly used to guide the high-definition soft film ring 302 from between the two rubber rollers 301 to fold outward and bypass the rotating drum 309, that is, the rotating drum 309 is in contact with the inner ring of the high-definition soft film ring 302;

[0025] The upper and lower ends of the rotating drum 309 are rotatably connected to the top plate 2 and the cabinet 1 in sequence through two connecting plates 304, that is, the two connecting plates 304 are fixedly connected to the top plate 2 and the cabinet 1 respectively, and the rotating drum 309 and the connecting plates 304 are rotatably connected. The outer drum 303 is arranged on the periphery of the rotating drum 309, and the upper and lower ends of the outer drum 303 are fixedly connected to the two connecting plates 304 respectively. One side of the cleaning cloth 310 is fixedly fitted on the inner wall of the outer drum 303, and the other side of the cleaning cloth 310 is fitted with the outer wall of the high-definition soft film ring 302.

[0026] In this embodiment, the opening edges of the upper and lower ends of the high-definition soft film ring 302 are fixedly connected with a belt ring 307, and the upper and lower ends of the eight rubber rollers 301 are provided with annular belt grooves 306, one side of the annular belt groove 306 is engaged with the inner ring of the belt ring 307, and the upper and lower ends of the steering roller 308 and the rotating drum 309 are respectively provided with a small annular groove and a large annular groove that are engaged with the inner ring of the belt ring 307. The inner ring of one belt ring 307 is squeezed and engaged with the two small annular grooves, the large annular groove and the eight annular belt grooves 306 respectively, and the lower end of the rotating drum 309 is coaxially fixed with a hand wheel 305. The two belt rings 307 are respectively in contact and sealed with the top plate 2 and the cabinet 1, and then the high-definition soft film ring 302 is used to seal the two belt rings 307, thereby realizing the sealing of the periphery of the 3D stereoscopic holographic imaging space between the cabinet 1 and the top plate 2, and thus preventing dust from falling in the 3D stereoscopic holographic imaging space;

[0027] It should be noted that the present application mainly observes the 3D stereoscopic image formed in the 3D stereoscopic holographic image through the high light transmittance of the high-definition soft film ring 302. Therefore, the high-definition soft film ring 302 needs to be prevented from being scratched when it rotates. Therefore, belt loops 307 are set at the upper and lower ends of the high-definition soft film ring 302, and then the two belt loops 307 are used to drive the high-definition soft film ring 302 to rotate. Compared with directly driving the high-definition soft film ring 302 to rotate, the inner ring of the high-definition soft film ring 302 is subjected to smaller traction force, which can effectively prevent the high-definition soft film ring 302 from being scratched. The outer wall surfaces of the rubber roller 301, the rotating drum 309 and the steering roller 308 that are in contact with the inner and outer rings of the high-definition soft film ring 302 are set to soft rubber or cloth, which can also prevent the high-definition soft film ring 302 from being scratched.

[0028] The utility model, by combining the high-definition soft film ring 302 in the dustproof mechanism 3 with the cabinet body 1 and the top plate 2, encloses the 3D holographic image space in the holographic display cabinet for visual communication, thereby effectively preventing dust from falling in the 3D holographic image space. In addition, dust will not fall on the outer surface of the four liquid crystal screens and the holographic glass in the 3D holographic image space, ensuring that the light emitted by the liquid crystal screen will not be blocked by dust.

[0029] The outer surface of the high-definition soft film ring 302 can be cleaned by manually rotating the rotating drum 309 through the hand wheel 305. After the rotating drum 309 rotates, the rotating drum 309 can drive the high-definition soft film ring 302 to rotate along the eight rubber rollers 301 around the periphery of the 3D stereoscopic holographic imaging space through the two belt loops 307. The outer wall of the rotating high-definition soft film ring 302 will pass through the cleaning cloth 310 on the inner ring of the outer drum 303 in turn, that is, the cleaning cloth 310 will wipe the outer wall of the high-definition soft film ring 302 in turn to ensure the cleanliness of the outer wall of the high-definition soft film ring 302.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
