Description

Technical Field

[0001] This utility model relates to the field of furniture decoration, and in particular to a three-dimensional depth-of-field display device. Background Technology

[0002] In the market for tourist souvenirs, gifts, and home decorations, decorative items such as refrigerator magnets, desktop picture frames, and ornaments have long been popular with consumers. However, existing products of this type have significant limitations in terms of visual effects, structural design, and functionality. Most decorative display devices on the market currently employ a single-layer structure. For example, common refrigerator magnets or decorative stickers are typically made of a single sheet of material (such as metal, ceramic, plastic, or rigid cardboard), with a flat pattern printed or engraved on its surface. The drawback of these products is that their display effect is limited to a two-dimensional plane, lacking a sense of three-dimensionality and visual depth. The images are monotonous and fail to create an immersive visual effect with spatial hierarchy, making it difficult to meet consumers' growing demand for high-end, exquisite decorative items.

[0003] To address the issue of flatness, some existing technologies attempt to introduce multi-layered structures to create a sense of depth. One approach involves using multiple layers of wood or metal sheets, carved with openwork to allow the lower layers' patterns to show through the openwork sections of the upper layers. However, such structures typically rely on adhesives to permanently hold the layers together. This means that once the product is assembled, it cannot be altered; users cannot change the internal patterns or adjust the layer order according to personal preference, resulting in extremely low interactivity and personalization. Furthermore, wood or metal materials are inherently opaque, relying on external light reflection, making it difficult to showcase rich, vibrant, and translucent color details.

[0004] Another known technique involves layering multiple transparent acrylic (PMMA) sheets to create a visual depth effect through physical spacing. However, these methods have significant problems with how the sheets are secured. They typically use simple magnetic adsorption or glue the sheets directly to the backing panel. The former results in a loose structure, with sheets prone to misalignment or slippage, leading to poor stability and durability; the latter completely sacrifices the product's replaceability and customizability, rendering it a disposable item. None of these methods provide a stable, reliable, and user-friendly overall structure for easy assembly and disassembly.

[0005] In summary, the display devices in the prior art have the following common problems: (1) the visual effect is flat and lacks a real sense of three-dimensional depth; (2) the multi-layer structure is mostly fixed, and users cannot easily change or adjust the internal patterns, resulting in poor interactivity; (3) the overall structure is not stable enough, or due to the fixing method, such as adhesive, it loses the potential for reusability and personalized customization. Utility Model Content

[0006] This utility model aims to solve the technical problems in the prior art mentioned above, and proposes a three-dimensional depth-of-field display device, which includes: a first frame, the first frame having an observation part, the observation part being a transparent cover or an open structure, for users to observe objects or patterns within the frame; a second frame, the first frame and the second frame being detachably connected, the first frame and the second frame together forming an accommodating space; at least two sheets, each sheet being a transparent material and each sheet having a different pattern, the at least two sheets being stacked to form a three-dimensional depth-of-field pattern, and the at least two sheets being placed in the accommodating space, allowing the three-dimensional depth-of-field pattern formed by the at least two sheets to be observed through the observation part.

[0007] Furthermore, the observation section is an opening on the first frame.

[0008] Furthermore, the stereoscopic depth display device includes a sliding rail mechanism, which allows the first frame and the second frame to slide relative to each other along a predetermined trajectory via the sliding rail mechanism, so as to achieve mutual combination and separation.

[0009] Furthermore, the slide rail mechanism includes a protruding strip disposed on the first frame and a grooved track disposed on the second frame that is adapted to the protruding strip, so that the first frame can slide relative to the second frame through the cooperation of the protruding strip and the grooved track.

[0010] Furthermore, the slide rail mechanism includes a protrusion disposed on the first frame and a positioning groove disposed on the second frame that is adapted to the protrusion. The protrusion and the positioning groove are used to lock the first frame and the second frame when they are in place.

[0011] Furthermore, a magnetic body is fixedly provided on the second frame to attract the second frame to the metal surface.

[0012] Furthermore, the second frame also has a snap-fit ​​portion for accommodating the magnetic body, the snap-fit ​​portion being provided with a spring tab for fixing the magnetic body.

[0013] Furthermore, the second frame is provided with a bracket, which can rotate and be fixed relative to the second frame to support the second frame.

[0014] Furthermore, the sheet material is acrylic.

[0015] Furthermore, the first and second frames are made of plastic, metal, or wood.

[0016] In summary, the 3D depth-of-field display device of this application combines structural stability, visual uniqueness, user interactivity, and scene versatility. Its detachable frame and multi-layered transparent sheet structure provide stable physical support while creating a customizable 3D depth-of-field visual effect. By introducing both magnetic and bracket-based fixing methods, the product's applicability is effectively expanded, meeting users' decorative and display needs in different scenarios.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0028] refer to Figures 1 to 6 A preferred embodiment of the stereoscopic depth-of-field display device 100 includes: a first frame 1 having an observation section 11; a second frame 2, wherein the first frame 1 and the second frame 2 are detachably connected, and the detachable connection can be achieved by setting fasteners or according to the frame structure, such as by means of slide rails, buckles, screws, magnets, etc. The first frame 1 and the second frame 2 together enclose a receiving space 3; at least two sheets 4, each sheet 4 being made of transparent material and having a different pattern (not shown in the figure), wherein at least two sheets 4 are stacked to form a stereoscopic depth-of-field pattern, and the stacked sheets 4 are placed in the receiving space 3, allowing the stereoscopic depth-of-field pattern formed by the at least two sheets 4 to be observed through the observation section 11. Figure 3 and Figure 4 Five sheets 4 are exemplarily shown. It is understood that the number of sheets 4 is not limited to five; different numbers of sheets 4 can be designed according to the size of the stereoscopic depth-of-field display device 100. Each sheet 4 can be freely combined and stacked to display different depth-of-field patterns. The mutually detachable first frame 1 and second frame 2 allow the sheets 4 to be replaced at any time, and there is no shaking when multiple sheets 4 are placed in the receiving space 3. Figure 6As shown, multiple sheets 4 are stacked within the receiving space 3, filling the entire space. This design uses two detachably connected frames to form the receiving space 3, which holds multiple layers of patterned transparent sheets 4, thus creating a visual experience with a sense of three-dimensionality and depth that cannot be achieved by traditional single-layer or fixed multi-layer structures. Simultaneously, the detachable structure provides a basis for replacing and customizing the sheets 4.

[0029] The sheet material 4 includes acrylic, PET, PC, glass, etc., preferably acrylic. Using acrylic ensures excellent light transmittance for a clear depth-of-field effect while providing good surface hardness, wear resistance, and printability, which is beneficial for fine pattern production and long-term preservation, and the cost is relatively controllable. The first frame 1 and the second frame 2 are made of plastic, metal, or wood. A variety of materials can be selected to give the product different appearances, textures, weights, and cost levels. Plastic is suitable for mass production and complex shapes, metal enhances texture and durability, and wood brings a natural and unique artistic feel, meeting the diverse needs of the market.

[0030] refer to Figures 1 to 5 In a preferred embodiment, the observation section 11 is an opening on the first frame 1. This arrangement provides a simple and reliable observation method without requiring the entire frame to be transparent, reducing manufacturing costs and process complexity. It is understood that a transparent cover plate can also be provided in the opening to effectively protect the internal sheet 4 from dust and scratches.

[0031] refer to Figure 3 and Figure 4 In a preferred embodiment, the stereoscopic depth display device 100 includes a slide rail mechanism 5, allowing the first frame 1 and the second frame 2 to slide relative to each other along a predetermined trajectory via the slide rail mechanism 5, thereby achieving mutual engagement and disengagement. The slide rail mechanism 5 provides a detachable connection method that offers precise guidance, smooth operation, and a stable connection. It avoids the use of other fasteners, such as screws, enabling rapid assembly and disassembly of the product and greatly improving the convenience and experience for users when replacing the sheet 4.

[0032] refer to Figure 3 , Figure 4 and Figure 6In a preferred embodiment, the slide rail mechanism 5 includes a protruding strip 51 disposed on the first frame 1 and a grooved track 52 disposed on the second frame 2 that is adapted to the protruding strip 51. The cooperation between the protruding strip 51 and the grooved track 52 allows the first frame 1 to slide relative to the second frame 2. The cooperation between the protruding strip 51 and the grooved track 52 is a simple, easy-to-manufacture, and low-cost sliding guide method. It ensures accurate movement trajectories of the two frames during assembly and disassembly, prevents misalignment, and guarantees the reliability of the connection.

[0033] refer to Figure 3 and Figure 4 In a preferred embodiment, the slide rail mechanism 5 includes a protrusion 53 disposed on the first frame 1 and a positioning groove 54 disposed on the second frame 2 that matches the protrusion 53. The protrusion 53 and the positioning groove 54 are used to lock the first frame 1 and the second frame 2 when they are in place. The positioning structure can provide clear tactile or audible feedback, such as a "click" sound, after the frame slides into place, allowing the user to clearly perceive that the engagement is complete. This effectively prevents accidental opening due to loose engagement, improving the structural stability and safety of the product.

[0034] refer to Figure 3 and Figure 4 In a preferred embodiment, a magnetic element 6 is preferably fixedly disposed on the inner side of the second frame 2 to attract the second frame 2 to a metal surface. It is understood that the magnetic element 6 can be disposed at any position, as long as it can attract the display device to the target surface. The built-in magnetic element 6 gives the display device the additional function of being used as a refrigerator magnet, greatly expanding its application scenarios (such as refrigerators, metal whiteboards, security doors, etc.), realizing a functional leap from desktop ornament to wall decoration. The figure shows an embodiment with two identical magnetic elements 6. It is understood that the number of magnetic elements 6 is not limited, and the number of magnetic elements 6 can be selected according to the size of the 3D depth-sensing display device 100.

[0035] refer to Figure 4 In a preferred embodiment, the second frame 2 preferably has a snap-fit ​​portion 7 on its inner side for accommodating the magnetic body 6. The snap-fit ​​portion 7 is provided with a spring tab 71 for fixing the magnetic body 6. The cooperation between the snap-fit ​​portion 7 and the spring tab 71 provides a way to fix the magnetic body 6 without adhesive, which facilitates rapid assembly on the production line and also facilitates future maintenance or replacement of the magnetic body 6, improving the manufacturability and maintainability of the product. It is understood that there is no limit to the number of snap-fit ​​portions 7, and the number of snap-fit ​​portions 7 can be set according to the number of magnetic bodies 6.
