Description

Technical Field

[0001] This disclosure relates to the field of refrigerators with door illumination function, and more particularly to a decorative panel assembly, a refrigerator door, and a refrigerator. Background Technology

[0002] Traditional refrigerator doors are often decorated with a single color or simple, fixed pattern, lacking personalization and interactivity. This makes them unsuitable for meeting the advanced demands of users for aesthetic design, functional diversity, and user experience in the context of smart home development. Existing refrigerator doors with lighting functions generally use fixed patterns or simple LED light strips, whose lighting effects and pattern styles cannot be adjusted according to user aesthetic preferences, failing to meet users' demands for personalized aesthetics and flexible usage scenarios.

[0003] With the upgrading of consumption, users' demand for customized and scenario-based home appliances is becoming increasingly prominent. However, there is a lack of existing technologies that can organically integrate the light-emitting function with the door structure and allow for easy replacement of the light-emitting pattern and flexible adjustment of the light transmission effect for refrigerator doors.

[0004] Traditional light-emitting structures are either integrated with the door body and difficult to disassemble and maintain, or the pattern replacement operation is complicated and the maintenance cost is high. They cannot take into account structural stability, ease of use and personalized needs. Therefore, there is an urgent need for a door light-emitting technology solution that is structurally reasonable, easy to operate and can flexibly switch the light-emitting patterns. Summary of the Invention

[0005] This disclosure provides a decorative panel assembly, a refrigerator door, and a refrigerator to solve the technical problem in the prior art that the existing door light-emitting structure cannot simultaneously meet the requirements of structural stability, ease of use, and personalization.

[0006] This disclosure provides a decorative panel assembly installed on a refrigerator door. The decorative panel assembly includes a bracket, a surface light source, a replaceable diaphragm, and a door panel. The bracket serves as a support base. The surface light source is mounted on one side of the bracket. The diaphragm is detachably attached to the side of the surface light source away from the bracket. The door panel covers the side of the diaphragm away from the surface light source and is fixedly connected to the bracket. The diaphragm is made of a transparent or semi-transparent material and has patterns or text printed on its surface. By replacing the diaphragm, the luminous pattern on the refrigerator door changes. The light emitted by the surface light source passes sequentially through the diaphragm and the door panel to form a visual luminous effect.

[0007] The membrane structure is partially transparent, where the area corresponding to the pattern or text is the transparent area and the remaining area is the light-blocking area. The membrane is constructed as a fully transparent structure, and the entire membrane of the fully transparent structure is a light-transmitting area; The lighting effect of the refrigerator door can be adjusted by selecting films with different light-transmitting structures.

[0008] The surface light source includes an LED light board, a light guide plate, and a diffuser plate. The LED light board is mounted on the bracket. The light guide plate is attached to the light-emitting side of the LED light board. The diffuser plate is attached to the side of the light guide plate away from the LED light board. The light emitted by the LED light board is uniformly diffused by the light guide plate and diffused by the diffuser plate to form a uniform backlight.

[0009] The door panel surface is formed with a preset pattern layer using a screen printing process. The preset pattern layer is adapted to the pattern or text on the surface of the diaphragm, and the two are superimposed to form a composite luminous pattern. The door panel is made of acrylic sheet or glass and is used to support and protect the diaphragm and the surface light source.

[0010] This disclosure also provides a refrigerator door body, including the above-mentioned decorative panel assembly. The refrigerator door body further includes a foaming assembly, and the decorative panel assembly and the foaming assembly are assembled into the refrigerator door body by detachable fastening.

[0011] The foaming component is provided with a spring support, a spring, a snap fastener rotating support bracket, a snap fastener rotating support, and a snap fastener on the side facing the decorative panel component. The spring support is vertically fixed to the surface of the foaming component, and the spring is sleeved on the spring support with one end abutting against the surface of the foaming component. The push-button rotating support bracket is two in number and symmetrically arranged on both sides of the spring support bracket. The two ends of the push-button rotating support bracket are respectively rotatably connected to the two push-button rotating support brackets. The middle part of the press buckle is fixedly connected to the press buckle rotating support column, the left end of the press buckle extends to the end of the spring away from the foaming component and is fastened to the spring, and the right end of the press buckle is provided with a locking claw structure.

[0012] The decorative panel assembly is provided with a claw, a limiting claw, and a lower support column on the side facing the foaming assembly; the foaming assembly is provided with a claw hole, a limiting claw hole, and a lower support column groove respectively corresponding to the positions of the claw, the limiting claw, and the lower support column. During assembly, the lower support column is first inserted into the lower support column slot to complete the initial positioning, the limiting claw is inserted into the limiting claw hole to restrict lateral displacement, and the claw is inserted into the claw hole and engages with the claw structure at the right end of the press buckle to complete the locking of the decorative panel assembly and the foam assembly. When the left end of the snap button is pressed, the snap button rotates around the snap button rotation pillar, and the right end claw structure lifts up and disengages from the claw, for removing the decorative panel assembly from the foam assembly.

[0013] The decorative panel assembly is provided with at least one of the claws, and each claw is evenly distributed along the edge of the decorative panel assembly.

[0014] The limiting claw can be replaced by the clamping claw, and the limiting claw hole on the foaming component can be replaced with a clamping claw hole that is compatible with the clamping claw.

[0015] The foaming assembly is also provided with a decorative cover, which is placed on the outside of the spring, the rotating support bracket of the snap fastener, the rotating support of the snap fastener and the snap fastener. The decorative cover is directly assembled with the foaming assembly and is used to cover the internal components.

[0016] The lower support column is provided in two places, and the two lower support columns are spaced apart and parallel along the length direction of the foaming component. The decorative panel component is provided with a corresponding slot that is adapted to the lower support column, and one lower support column is engaged with one corresponding slot.

[0017] It also includes a decorative cover, which is a ring structure. The decorative cover is fitted onto the outer edge of the door panel, and one side of the decorative cover is directly connected to the bracket to cover the connection gap between the door panel and the bracket.

[0019] The technical solutions provided in this disclosure have the following advantages compared with the prior art: The decorative panel assembly, refrigerator door, and refrigerator provided in this disclosure offer infinitely adjustable luminous patterns through the replaceable film. Users can flexibly replace the film according to their scenarios and preferences, breaking through the limitations of traditional fixed patterns and adapting to personalized aesthetic needs in smart home scenarios. Furthermore, the layered structure of the surface light source, film, and door panel ensures that the light emitted by the surface light source is uniformly diffused and can completely pass through the pattern or text area of ​​the film, presenting a clear and soft visual luminous effect through the door panel. This avoids the problems of uneven light spots and blurred patterns in traditional LED light strips. At the same time, the door panel can prevent external dust and moisture from contacting the internal components, extending the lifespan of the film and surface light source, balancing luminous effect and structural durability. It should be noted that the solution only achieves the luminous function through modular disassembly and the addition of internal components, without changing the core structure of the decorative panel assembly. It can be adapted to various types of doors, such as single doors, double doors, and French doors, and has a wide range of application scenarios. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0026] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0027] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, inside, outside, inner side, outer side, below, below, above, front, back, etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly; for example, an element described as being below or under other elements or features will subsequently be oriented above or above other elements or features. Therefore, the example term "below" can include orientations of "above" and "below". The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.

[0028] refer to Figures 1-9This disclosure provides a decorative panel assembly 001, which is installed on a refrigerator door 01. The decorative panel assembly 001 includes a bracket 0013, a surface light source 0015, a replaceable diaphragm 0016, and a door panel 0017. The bracket 0013 serves as a support base. The surface light source 0015 is installed on one side of the bracket 0013. The diaphragm 0016 is detachably attached to the side of the surface light source 0015 away from the bracket 0013. The door panel 0017 covers the side of the diaphragm 0016 away from the surface light source 0015 and is fixedly connected to the bracket 0013. The diaphragm 0016 is made of a transparent or semi-transparent material and has patterns or text printed on its surface. By replacing the diaphragm 0016, the luminous pattern on the refrigerator door 01 changes. The light emitted by the surface light source 0015 passes through the diaphragm 0016 and the door panel 0017 in sequence to form a visual luminous effect.

[0029] For example, the application scenario is to use the foaming component of the refrigerator door in conjunction with the aforementioned decorative panel component, and the subsequent solution will be further explained.

[0030] That is, the refrigerator door 01 includes a decorative panel assembly 001 and a foaming assembly 002, which are assembled into the refrigerator door 01 by detachable fastening.

[0031] For example, the detachable snap-fit ​​installation can be achieved through the cooperation of the snap fastener 0023, the claw 0011, and the slot. Specific implementation details can be found in subsequent solutions. For instance, the foam component 002 may be equipped with a spring 0021, a snap fastener rotating support 0024, and a snap fastener 0023, while the decorative panel component 001 may be equipped with a claw 0011. During installation, the claw 0011 of the decorative panel component 001 is inserted into the claw hole 003 of the foam component 002 and engages with the snap fastener 0023. During disassembly, pressing one end of the snap fastener 0023 causes it to rotate around the snap fastener rotating support 0024, while the other end lifts and disengages from the claw 0011, allowing the decorative panel component 001 to be removed from the foam component 002. This entire process requires no screws or other fasteners, making it a tool-free, detachable snap-fit ​​structure.

[0032] For example, the detachable bonding means that the diaphragm 0016 and the surface light source 0015 do not need to be fixed with adhesive substances such as glue or tape. The diaphragm 0016 is bonded to the surface light source 0015 by its own flatness and slight friction, such as the surface of the diffuser plate of the surface light source 0015. For example, when the diaphragm 0016 is made of flexible transparent PET material, the diaphragm 0016 can be directly aligned with the edge of the surface light source 0015 and bonded. When disassembling, the diaphragm 0016 can be easily peeled off by pinching one corner with your fingers. When replacing the diaphragm 0016, it can be re-aligned and bonded. This is a non-destructive disassembly and re-bonding connection method.

[0033] For example, the material of the transparent or semi-transparent film 0016 includes either PET polyethylene terephthalate film or PC polycarbonate film; the surface pattern or text can be made by screen printing or UV printing process. For example, if a partial light transmission effect is required, light-blocking ink can be screen printed on the film 0016 to form a background, leaving only the main area of ​​the pattern transparent, such as the star part of a star pattern being transparent while the rest of the area is light-blocking, and light passing through the star area forms a glowing star; if a full light transmission effect is required, a semi-transparent pattern, such as a light-colored floral pattern, can be printed on the transparent film 0016, and when light passes through, it presents an overall glowing effect with the pattern.

[0034] For example, the structure of the surface light source 0015 may include an LED light panel, a light guide plate, and a diffuser plate. The LED light panel is the main body of the light source and may be a surface-mount LED array. The light guide plate is made of acrylic material with microstructures on its surface, which can uniformly guide the side light emitted by the LED light panel to the front. The diffuser plate is made of frosted PET material and is attached to the front of the light guide plate to soften the light emitted by the light guide plate, avoid LED light spots, and ultimately form a uniform and soft surface light, ensuring that the pattern of the film 0016 is clear after light transmission.

[0035] For example, the material of the door panel 0017 can be a transparent acrylic sheet or tempered glass; the surface can be made with a light-colored background or simple patterns through screen printing. For example, after screen printing a light gray background, it can be superimposed with the blue ocean pattern of the membrane 0016. When light passes through, it presents a composite effect of light gray background and blue glowing ocean, which not only enhances the aesthetics, but also avoids the pattern of the membrane 0016 from appearing abrupt due to the background being too light.

[0036] In this way, the detachable fastening installation of the decorative panel assembly 001 and the foaming assembly 002 allows for the replacement of the film 0016 and the maintenance of the surface light source 0015 without disassembling the entire refrigerator door 01 or damaging the door structure. For example, when replacing the film 0016, the decorative panel assembly 001 can be removed simply by pressing the fastening structure, the old film 0016 can be peeled off, the new film 0016 can be attached, and then the fastening can be reattached. No professional tools are required throughout the process, the operation time is short, and the maintenance difficulty and cost are significantly reduced. The replaceable film 0016 allows for infinitely adjustable luminous patterns. Users can flexibly replace the film 0016 according to the scene and their preferences, breaking through the limitations of traditional fixed patterns and adapting to the personalized aesthetic needs of smart home scenarios.

[0037] Furthermore, the system employs a layered structure of surface light source 0015, diaphragm 0016, and door panel 0017. This allows the light emitted by the surface light source 0015 to be evenly diffused and fully penetrate the pattern or text area of ​​the diaphragm 0016, then pass through the door panel 0017 to present a clear and soft visual lighting effect, avoiding the problems of uneven light spots and blurred patterns in traditional LED light strips. At the same time, the door panel 0017 can prevent external dust and moisture from contacting the internal components, extending the lifespan of the diaphragm 0016 and surface light source 0015, balancing lighting effect and structural durability. It should be noted that the solution only achieves the lighting function through modular disassembly and the addition of internal components, without changing the core structure of the refrigerator door 01, such as the heat insulation performance of the foam component 002 and the door's opening and closing sealing. It can be adapted to various types of refrigerator doors 01, such as single-door, double-door, and side-by-side doors, and has a wide range of application scenarios.

[0038] Considering the different options available for the diaphragm 0016, in this embodiment of the disclosure, the diaphragm 0016 is configured to be partially translucent. In this partially translucent structure, the area corresponding to the pattern or text is the translucent area, and the remaining area is the light-blocking area. The diaphragm 0016 is constructed as a fully transparent structure, and the entire diaphragm 0016 is a transparent area. The lighting effect of the refrigerator door 01 can be adjusted by selecting a membrane 0016 with different light transmission structures.

[0039] For example, the partially translucent membrane 0016 can be made of transparent PET substrate, and partitioning can be achieved through screen printing. No ink is printed in the area of ​​the cartoon bear pattern, preserving the transparency of the substrate and forming a translucent area. Black acrylic opaque ink is printed in the remaining areas outside the pattern. When the surface light source 0015 emits light, the light only passes through the area of ​​the cartoon bear, and the door panel 0017 only shows the effect of the bear shining brightly and the background being dark, which is suitable for the scene of low light pollution and highlighting the cute atmosphere of the refrigerator in the bedroom at night.

[0040] For example, the fully transparent membrane 0016 can be made of a high-transmittance PC substrate, and a light gray semi-transparent geometric grid pattern can be printed on the surface of the substrate using a UV printing process. The membrane 0016 has no light-blocking areas and is entirely transparent. When the surface light source 0015 emits light, the light passes evenly through all areas of the membrane 0016, and the door panel 0017 presents an overall soft glow with the geometric grid faintly appearing with the light, which is suitable for brightening the kitchen and refrigerator space during the day and creating a simple and beautiful scene.

[0041] For example, adjusting the lighting effect of the refrigerator door 01 can be understood as follows: In the exemplary scenario, during the day, the user can replace the fully transparent film 0016 to make the refrigerator door 01 illuminate as a whole, thereby improving the brightness of the kitchen; at night, the user can replace the partially transparent film 0016 to illuminate only the patterned area, avoiding strong light from affecting nighttime rest; when replacing, there is no need to disassemble the door or modify the surface light source 0015, but only to peel off the old film 0016 and align and attach the new film 0016, which takes less time and achieves tool-free and quick adjustment.

[0042] In this way, a solution is formed by differentiating the light-transmitting structure of the membrane 0016. For the need to highlight patterns or text and focus visual attention, a partially light-transmitting membrane 0016 is set up, with the pattern or text area as the light-transmitting zone and the rest of the area as the light-blocking zone. This allows light to be presented only through the light-transmitting zone, solving the problem of traditional light emission without a visual focus. At the same time, for the need to brighten the overall light and create a sense of transparency, a fully light-transmitting membrane 0016 is set up, making the entire membrane 0016 a light-transmitting zone. Visual distinction is achieved only through semi-transparent patterns or text, solving the problem of traditional solutions not being able to emit light throughout. Moreover, both types of membrane 0016 can share the existing decorative panel component 001. Users only need to replace the membrane 0016 to switch the lighting effect, ultimately solving the problems of non-adjustable light transmission effect and poor scene adaptability.

[0043] Considering the specific formation scheme of the surface light source 0015, in this embodiment of the disclosure, the surface light source 0015 includes an LED light board, a light guide plate and a diffuser plate. The LED light board is mounted on a bracket, the light guide plate is attached to the light-emitting side of the LED light board, and the diffuser plate is attached to the side of the light guide plate away from the LED light board. The light emitted by the LED light board is uniformly diffused by the light guide plate and diffused by the diffuser plate to form a uniform backlight.

[0044] For example, an LED light board refers to a basic light source assembly composed of LED beads, circuit boards and driving components. An example solution is as follows: 2835 model surface mount LED beads are uniformly soldered onto an FR-4 epoxy resin circuit board at a spacing of 10mm; the LED light board is fixed to the edge area of ​​the bracket by screws or double-sided adhesive, so that its light emission direction is towards the side of the light guide plate, avoiding direct irradiation of the 0016 film and the generation of localized overly bright spots.

[0045] For example, a light guide plate is a core component that enables the conversion of light from linear or point-like to planar light. An exemplary solution is as follows: a 5mm thick transparent acrylic sheet is used, and micro-dots are made on the side of the sheet away from the LED light panel using a laser engraving process; the light guide plate is attached to the light-emitting side of the LED light panel with transparent double-sided adhesive. After the light emitted from the LED light panel enters the light guide plate, it is refracted and reflected by the micro-dots and evenly distributed on the entire front of the light guide plate, thus completing the conversion of linear light to planar light.

[0046] For example, the diffuser plate refers to a component that further softens the light and eliminates residual light spots. An exemplary solution is to use a frosted PET plate, which is attached to the side of the light guide plate away from the LED light plate by electrostatic adsorption or transparent double-sided adhesive, i.e., the front side of the light guide plate. When the planar light emitted by the light guide plate passes through the diffuser plate, it is refracted multiple times by the tiny protrusions on the frosted surface, completely eliminating the tiny light spots that may remain in the micro-dots of the light guide plate, and finally forming a uniform backlight with small brightness deviation, ensuring that the luminous brightness of each area of ​​the cartoon pattern or text mark on the diaphragm 0016 is consistent.

[0047] After the light is uniformly distributed by the light guide plate and diffused by the diffuser plate, a uniform backlight is formed. An exemplary light path is as follows: linear light rays are emitted from the edge of the LED light board, enter the side of the light guide plate, are refracted and reflected by the micro-dots of the light guide plate, and are evenly distributed on the front of the light guide plate. The light rays penetrate the front of the light guide plate, enter the diffuser plate, are refracted multiple times by the frosted surface of the diffuser plate to eliminate light spots, and are emitted from the front of the diffuser plate to form a backlight with uniform brightness covering the corresponding area. At this time, the pattern or text of the film 0016 attached to the front of the diffuser plate can be presented completely and clearly with the uniform backlight.

[0048] In this way, by setting up a layered structure with multiple components working together to create a surface light source 0015, a complete and uniform backlight formation mechanism is constructed from light source generation to light optimization. Using an LED light panel as the basic light source, stable light emission is provided, solving the problems of insufficient brightness and short lifespan of traditional light sources. The linear or point light from the LED light panel is converted into surface light by a light guide plate, achieving initial light homogenization and solving the problem of uneven light distribution. Then, the light from the light guide plate is further softened by a diffuser plate to eliminate residual light spots, ultimately forming a backlight with a wide coverage and uniform brightness. This ensures that the patterns or text on the film 0016 can be presented clearly and without deviation, completely solving the core problem of uneven illumination of the refrigerator door 01 in the prior art.

[0049] Considering the formation scheme of the composite light-emitting pattern, in this embodiment of the disclosure, the surface of the door panel 0017 is formed with a preset pattern layer by screen printing process. The preset pattern layer is adapted to the pattern or text on the surface of the diaphragm 0016. The two are superimposed to form a composite light-emitting pattern. The door panel 0017 is made of acrylic sheet or glass material. The door panel 0017 is used to support and protect the diaphragm 0016 and the surface light source 0015.

[0050] For example, the screen printing process to form a preset pattern layer refers to creating a fixed pattern layer on the surface of the door panel 0017 using screen printing technology. For example, semi-transparent light gold screen printing ink is selected, and fine lines of scrolling grass patterns are printed on the surface of the door panel 0017 using screen printing. During printing, the ink is controlled and cured by baking to form a preset pattern layer that is firmly attached and has uniform light transmission. This pattern layer will not completely block the light and only serves as a background base for composite light emission.

[0051] For example, the preset pattern layer is adapted to the pattern or text on the surface of the membrane 0016, meaning that the two match in style and size to form a harmonious composite effect. An example adaptation relationship is as follows: the preset pattern layer of the door panel 0017 is a light gold scroll pattern, and the pattern on the surface of the membrane 0016 is a red plum blossom, with the size adapted to the panel; when the surface light source 0015 emits light, the light passes through the red plum blossom of the membrane 0016 and the light gold scroll pattern of the door panel 0017 in sequence, ultimately presenting a layered effect of the red plum blossom emitting light on the background of the light gold scroll pattern; if the membrane 0016 is replaced with a blue crane, the composite effect becomes the blue crane emitting light on the background of the light gold scroll pattern, and the adaptability is not limited by the pattern type.

[0052] In this way, by combining pattern overlay with highly adaptable material selection, the dual goals of upgrading visual effects and strengthening structural protection are achieved. On the one hand, a preset pattern layer is silkscreened on the surface of the door panel 0017, making it compatible with the pattern or text on the diaphragm 0016. This transforms single pattern illumination into composite illumination of the diaphragm 0016 pattern and the preset pattern on the panel, solving the problem of traditional illumination lacking layered aesthetics. On the other hand, acrylic sheets or glass are selected as the material for the door panel 0017. While ensuring light transmittance to present the composite pattern, the material's hardness and structural strength are used to block external damage, providing physical protection for the diaphragm 0016 and the surface light source 0015. Ultimately, this solves the dual problems of insufficient visual effects and lack of structural protection in existing technologies.

[0053] Considering the specific structural scheme of the detachable structure provided on the foaming component 002, in this embodiment of the present disclosure, the foaming component 002 is provided with a spring support 0022, a spring 0021, a snap fastener rotating support 0024 bracket, a snap fastener rotating support 0024 and a snap fastener 0023 on the side facing the decorative panel component 001. Spring support 0022 is vertically fixed to the surface of foam component 002, and spring 0021 is sleeved on spring support 0022 with one end abutting against the surface of foam component 002. There are two snap-lock rotating support brackets 0025, which are symmetrically arranged on both sides of the spring support 0022. The two ends of the snap-lock rotating support 0024 are rotatably connected to the two snap-lock rotating support brackets 0025 respectively. The middle part of the snap fastener 0023 is fixedly connected to the snap fastener rotating support 0024. The left end of the snap fastener 0023 extends to the end of the spring 0021 away from the foaming component 002 and engages with the spring 0021. The right end of the snap fastener 0023 is provided with a locking claw 0011 structure.

[0054] For example, the spring support 0022 can be made of ABS engineering plastic and is integrally molded by injection molding or fixed to the surface of the foam component 002 by screws, corresponding to the position of the claw 0011 of the decorative panel component 001; the spring 0021 is a stainless steel compression spring, which is sleeved on the spring support 0022, with its lower end abutting against the surface of the foam component 002 and its upper end fastening to the left end of the press buckle. When the press buckle 0023 is pressed, the spring 0021 is compressed and stores the restoring force. After releasing, the spring 0021 rebounds and drives the press buckle 0023 to reset.

[0055] For example, the press buckle rotating support bracket 0025 consists of two symmetrical L-shaped plastic parts, which are fixed to the surface of the foam component 002 by screws and are located on both sides of the spring support 0022; the press buckle rotating support 0024 is a stainless steel round rod, with both ends inserted into the reserved holes of the two brackets 0013 to form the rotation fulcrum of the press buckle 0023.

[0056] For example, the snap fastener 0023 is made of PP plastic, and its middle part is integrally molded or tightly fitted onto the snap fastener rotating support 0024 by injection molding, and can rotate synchronously with the support. Its left end has a U-shaped groove, and its right end has a hook-shaped claw 0011 structure. When the left end of the snap fastener 0023 is pressed, the snap fastener 0023 rotates clockwise around the rotating support, and the right-end claw 0011 structure lifts upward, disengaging from the claw 0011 of the decorative panel assembly 001 to unlock. After releasing, the spring 0021 rebounds, pushing the left end of the snap fastener 0023 back upward, and the snap fastener 0023 rotates counterclockwise around the rotating support, causing the right-end claw 0011 structure to return downward and re-engage into the claw hole 003, completing the locking process.

[0057] Thus, through the detachable structure created by the synergistic action of spring 0021, snap fastener 0023, and snap fastener rotating support 0024, a tool-free, quick-assembly and disassembly locking and unlocking mechanism is constructed. The spring support 0022 serves as the basic load-bearing component, with spring 0021 providing elastic restoring force. The snap fastener rotating support 0024 is fixed by symmetrically arranged snap fastener rotating support brackets 0025, allowing snap fastener 0023 to rotate around the support. The left end of snap fastener 0023 engages with spring 0021 to store restoring potential energy, while the right end features a locking claw structure for locking. When pressed, snap fastener 0023 rotates around the rotating support, and the right-end locking claw structure lifts to unlock. After releasing, the spring drives snap fastener 0023 to reset and lock. This structure eliminates the need for screws or other fasteners; the decorative panel assembly 001 and foam assembly 002 can be assembled and disassembled solely through a pressing action, completely solving the problems of inconvenient disassembly and high maintenance costs associated with traditional connection methods. This provides a convenient operational basis for replacing the diaphragm 0016 and repairing the surface light source 0015.

[0058] Considering the adaptation scheme of the decorative panel assembly 001 to the detachable structure of the foaming assembly 002, in this embodiment of the present disclosure, the decorative panel assembly 001 is provided with a claw 0011, a limiting claw 0012, and a lower support column 0018 on the side facing the foaming assembly 002; the foaming assembly 002 is provided with a claw hole 003, a limiting claw hole 004, and a lower support column slot 0029 respectively at the positions corresponding to the claw 0011, the limiting claw 0012, and the lower support column 0018; during assembly, the lower support column 0018 is first inserted into the lower support column slot 0018. Initial positioning is completed within 029. The limiting claw 0012 is inserted into the limiting claw hole 004 to limit lateral displacement. The locking claw 0011 is inserted into the locking claw hole 003 and engages with the locking claw structure at the right end of the pressing buckle 0023 to lock the decorative panel assembly 001 and the foam assembly 002. When the left end of the pressing buckle 0023 is pressed, the pressing buckle 0023 rotates around the pressing buckle rotating support 0024, and the right end locking claw structure is lifted and disengaged from the locking claw 0011, which is used to remove the decorative panel assembly 001 from the foam assembly 002.

[0059] For example, the lower support column 0018 can be made of ABS engineering plastic and is integrally injection molded with the back of the decorative panel assembly 001. Two columns are provided, located at the lower left and lower right corners of the decorative panel assembly 001 respectively, with a gap between them. The lower support column slot 0029 is a cylindrical groove opened at the corresponding position on the surface of the foam assembly 002. During assembly, the lower support column 0018 is aligned with the slot and inserted to quickly determine the initial installation position of the decorative panel assembly 001, avoiding repeated adjustments.

[0060] For example, the limiting claw 0012 is an L-shaped plastic protrusion integrally formed on the back of the decorative panel assembly 001; the limiting claw hole 004 is a rectangular hole corresponding to the surface of the foam assembly 002. After the lower support 0018 is inserted into the slot, the decorative panel assembly 001 is gently pressed, and the limiting claw 0012 can be elastically inserted into the hole, restricting the left and right lateral displacement of the decorative panel assembly 001, and ensuring that the subsequent claw 0011 can accurately align with the claw hole 003.

[0061] For example, the claw 0011 is a barbed structure on the back of the decorative panel assembly 001, corresponding to the circular claw hole 003 on the foam assembly 002. During assembly, after the limiting claw 0012 is engaged, the decorative panel assembly 001 is pressed down, and the claw 0011 passes through the claw hole 003. Its barb engages with the barb groove of the claw structure on the right end of the press buckle 0023, thus locking it in place. During disassembly, the left end of the press buckle 0023 on the foam assembly 002 is pressed down, and the press buckle 0023 rotates around the rotating support column. The claw structure on the right end lifts up and disengages from the claw barb. At this time, gently pull the decorative panel assembly 001 outward, and the claw 0011, limiting claw 0012, and lower support column 0018 will sequentially disengage from their corresponding holes or grooves, completing the disassembly process without any tools.

[0062] In this way, the adaptable structure, with its step-by-step positioning, dual limiting, and convenient unlocking, works synergistically with the detachable structure of the foam component 002. Initial positioning during assembly is achieved by inserting the lower support column 0018 into the lower support column slot 0029, solving the alignment difficulties of traditional assembly methods. Lateral displacement is limited by inserting the limiting claw 0012 into the limiting claw hole 004, solving the problem of easy displacement after connection. Stable locking is achieved by inserting the claw 0011 into the claw hole 003 and engaging with the press buckle 0023. Simultaneously, the rotation unlocking mechanism of the press buckle 0023 allows for tool-free disassembly. Ultimately, this constructs an adaptable structure that is accurate in positioning, stable in locking, and easy to assemble and disassemble, completely resolving the assembly and maintenance pain points of traditional connection methods.

[0063] Considering one of the configuration schemes for the engagement position on the decorative panel assembly 001, in this embodiment of the disclosure, the decorative panel assembly 001 is provided with at least one claw 0011, and each claw 0011 is evenly distributed along the edge of the decorative panel assembly 001.

[0064] For example, the number of claws 0011 needs to meet the basic locking requirements and can be flexibly adjusted according to the size of the decorative panel assembly 001. Therefore, the number of claws 0011 is limited to at least one.

[0065] For example, the finger claws 0011 are evenly distributed along the edge of the decorative panel assembly 001, with equal spacing at the edge, to ensure symmetrical force distribution and avoid deformation of the snap fastener 0023 or warping of the panel due to excessive force on one of the claws.

[0066] For example, the claw 0011 may be a protruding structure protruding from the decorative panel assembly 001, which may be an integrally formed structure of at least a portion of the decorative panel assembly 001, or the claw 0011 may be detachably mounted in the decorative panel assembly 001.

[0067] In this way, by matching the number of claws and evenly distributing them along the edges, the decorative panel component 001 and the foaming component 002 are stably locked and subjected to balanced forces during assembly and disassembly. Specifically, at least one claw 0011 is provided on the decorative panel assembly 001. In practical applications, there can be one or more claws to improve stability. All claws 0011 are evenly distributed along the edges of the decorative panel assembly 001, such as the top and bottom edges, left and right edges, or all four edges. Each claw 0011 is adapted to the corresponding claw hole 003 and press buckle 0023 structure on the foaming component 002. During assembly, the evenly distributed claws 0011 engage with the corresponding press buckle 0023 simultaneously, so that the force is evenly distributed at each point on the edge of the decorative panel assembly 001, avoiding panel tilting or loosening due to excessive local force. During disassembly, after pressing the corresponding press buckle 0023, each claw 0011 disengages simultaneously, ensuring that the panel can be removed smoothly, solving the problems of disassembly and assembly jamming and component damage caused by traditional non-uniform claws 0011.

[0068] Considering alternative solutions for the limiting claw 0012, in this embodiment of the disclosure, the limiting claw 0012 can be replaced with the clasp 0011. At the same time, the limiting claw hole 004 on the foaming component 002 is replaced with the clasp hole 003 that is adapted to the clasp 0011.

[0069] For example, the replaced limiting claw 0012 is completely identical to the original claw 0011 in structure, material, and size, requiring no additional new parts. For instance, the original claw 0011 is a hook-shaped structure made of ABS material, while the original limiting claw 0012 is an L-shaped protrusion made of PP material. After replacement, the structure of the limiting claw 0012 is changed to the same hook shape as the original claw, the material remains ABS, and the size is completely identical to the original claw, ensuring that it can share the production mold with the original claw 0011, thus reducing manufacturing costs.

[0070] For example, the replaced hole position is structurally identical to the original claw hole position 003, ensuring that the new claw 0011 can be accurately inserted and simultaneously achieve limiting and locking. For instance, the original limiting claw hole position 004 is a rectangular hole opened on the foaming component 002, and the original claw hole position 003 is a circular hole; after replacement, the original rectangular limiting claw hole position 004 is changed to a circular hole identical to the original claw hole position 003. After the new claw 0011 is inserted into this circular hole, the gap between the hole wall and the root of the claw 0011 is small, which can limit lateral displacement. At the same time, the barb of the claw 0011 can accurately engage with the claw structure of the press buckle 0023, achieving dual functions.

[0071] In this way, the limiting claw 0012 on the decorative panel assembly 001 is replaced with a claw whose structure is completely identical to the original claw. Simultaneously, the limiting claw hole 004 on the foam assembly 002, which is adapted to the limiting claw, is replaced with a claw hole 003 that matches the size and shape of the claw. During operation, the replaced claw 0011 retains the function of the original limiting claw in restricting lateral displacement; after being inserted into the new claw hole 003, the gap fit between the claw 0011 and the hole prevents the decorative panel assembly 001 from shifting left or right. It also possesses the stable locking function of the original claw; the barb structure of the claw 0011 engages with the press buckle 0023 of the foam assembly 002, achieving a fixed connection between the decorative panel assembly 001 and the foam assembly 002. Ultimately, through this dual-purpose claw and single-hole adaptation, the number of parts is reduced, processing and maintenance costs are lowered, while ensuring connection stability and positioning accuracy.

[0072] Considering a stable solution for detachable installation between the foaming component 002 and the decorative panel component 001, in this embodiment of the disclosure, the foaming component 002 is further provided with a decorative cover 0026. The decorative cover 0026 covers the outside of the spring 0021, the press buckle rotating support bracket 0025, the press buckle rotating support 0024 and the press buckle 0023. The decorative cover 0026 is directly assembled with the foaming component 002 and is used to cover the internal components.

[0073] For example, the decorative cover 0026 can be made of ABS engineering plastic and has an overall U-shaped groove structure with the opening facing the decorative panel assembly 001. Its internal space dimensions are set according to the overall outline of the covered parts. There is a gap between the inner wall of the decorative cover 0026 and each part, which not only avoids friction between the parts and the cover during operation, but also ensures complete coverage. A circular recess is provided at the left end of the press buckle 0023 to facilitate the insertion and pressing of fingers, while avoiding interference between the press buckle and the cover when it is reset.

[0074] For example, in the direct assembly method with the foam component 002, the decorative cover 0026 does not require additional connectors and is fixed to the foam component 002 through its own structure. For instance, the decorative cover 0026 has three elastic buckles at its bottom, and the foam component 002 has corresponding buckle holes. The decorative cover 0026 is aligned with the holes and pressed down, and the buckles elastically engage with the holes to complete the fixation. Alternatively, the decorative cover 0026 has two screw holes on its edge, and the foam component 002 has pre-embedded nuts at corresponding positions. The decorative cover 0026 is tightened and fixed by self-tapping screws. Both methods can achieve a stable connection between the decorative cover 0026 and the foam component 002 without damaging the original structure of the foam component 002.

[0075] In this way, a stable auxiliary structure with both protective and aesthetic functions is constructed by adding a decorative cover 0026. Specifically, the decorative cover 0026 is directly assembled onto the foam component 002, so that the decorative cover 0026 completely covers the outside of the spring 0021, the push-button rotating support bracket 0025, the push-button rotating support 0024, and the push-button 0023, forming a closed protective space. During operation, the decorative cover 0026 not only prevents dust and moisture from entering the internal components, avoiding spring corrosion and push-button jamming, and ensuring the long-term stable operation of the detachable structure, but also conceals the internal components, improving the visual cleanliness of the area where the foam component 002 and the decorative panel component 001 meet. At the same time, the decorative cover 0026 provides operating space for the push-button, such as a recess or opening in the area corresponding to the left end of the push-button 0023, ensuring that the push-to-unlock action is not affected by obstruction. Together with the detachable installation structure, it achieves a stable protection effect without interfering with disassembly and assembly, solving the protection and aesthetic defects of traditional exposed structures.

[0076] Considering another installation scheme for the initial positioning between the decorative panel assembly 001 and the foam assembly 002, in this embodiment of the present disclosure, two lower support columns 0018 are provided. The two lower support columns 0018 are spaced apart and parallel along the length direction of the foam assembly 002. The decorative panel assembly 001 is provided with a corresponding slot adapted to the lower support column 0018. One lower support column 0018 cooperates with a corresponding lower support column slot 0029.

[0077] For example, the length of the foam component 002 corresponds to the size of the refrigerator main door. The lower support is made of ABS engineering plastic, which is compatible with the thickness of the decorative panel. The two lower support 0018 are located at 1 / 4 and 3 / 4 of the length of the foam component 002, respectively, with a gap between them. The axes of the two support are parallel to each other and are perpendicular to the surface of the foam component 002 facing the decorative panel, ensuring that the insertion into the slot will not cause jamming due to tilt.

[0078] For example, the lower support slot 0029 is a cylindrical groove injection molded on the back of the decorative panel. The center distance between the two slots is exactly the same as the center distance between the two lower supports 0018 on the foam component 002. The inner wall of the slot is fitted with a silicone pad. After the lower support 0018 is inserted, the silicone pad deforms slightly, which increases the friction to prevent the panel from loosening and avoids wear of the parts caused by hard contact. This ensures that the lateral displacement of the panel after initial positioning is negligible and the rotational offset is negligible.

[0079] Thus, through a two-point support and parallel arrangement optimized initial positioning structure, specifically, two lower support pillars 0018 are set on the foam component 002, spaced apart and parallel along the length of the foam component 002, while two matching slots are opened at corresponding positions on the decorative panel component 001. During operation, in the initial assembly stage, the two lower support pillars are inserted into the corresponding slots to form a two-point positioning structure. The parallel arrangement of the lower support pillars 0018 restricts the rotational freedom of the decorative panel component 001, preventing rotation around a single pillar, while the spaced arrangement restricts lateral displacement, preventing the panel from shifting left or right. Under this dual constraint, high-precision initial positioning is achieved, ensuring that the subsequent limiting claws 0012 and clasps 0011 can accurately align with the holes on the foam component 002 in one go, without repeated adjustments. This solution significantly improves the stability and efficiency of initial positioning by simply increasing the number of lower support pillars 0018 and optimizing their arrangement.

[0080] Considering the overall aesthetics and stability of the door's light-emitting structure, in this embodiment of the present disclosure, the refrigerator door 01 also includes a decorative cover 005. The decorative cover 005 is a ring structure. The decorative cover 005 is fitted onto the outer edge of the door panel 0017, and one side of the decorative cover 005 is directly connected to the bracket 0013 to cover the connection gap between the door panel 0017 and the bracket 0013.

[0081] In this way, an optimized structure integrating aesthetics, protection, and reinforcement is constructed by adding a ring-shaped decorative cover 005. The ring-shaped decorative cover 005 is fitted onto the outer edge of the door panel 0017, with one side directly connected to the bracket 0013 without the need for additional connectors. On the one hand, the ring-shaped shielding surface of the decorative cover 005 completely covers the connection gap between the door panel 0017 and the bracket 0013, eliminating visual imperfections and improving the overall aesthetics of the door's luminous structure. On the other hand, the decorative cover 005, through its connection with the bracket 0013, strengthens the fixation between the door panel 0017 and the bracket 0013, reducing the risk of panel loosening. At the same time, it prevents external dust and moisture from entering the interior through the gaps, avoiding mold growth on the diaphragm 0016 and short circuits in the surface light source 0015. Ultimately, without affecting the luminous effect, it balances the exquisite appearance and structural stability.

[0082] This disclosure also provides a refrigerator, including the refrigerator door 01 described above, which can achieve all the effects of the refrigerator door 01 described above, and will not be described in detail here.

[0083] To better understand the solutions for the decorative panel assembly 001, the refrigerator door 01, and the refrigerator provided in this disclosure, the following exemplary description is provided: The decorative panel assembly 001 provided in this embodiment is installed on a refrigerator door 01 with a replaceable pattern. By setting a replaceable colored film on the front of the light source, the pattern and light-transmitting area can be changed, thereby improving the visual effect and user experience of the refrigerator door.

[0084] like Figure 1 As shown, the refrigerator door 01 is composed of a decorative panel assembly 001 and a foaming assembly 002, as... Figure 2 and Figure 3 As shown, on the foaming component 002, there is a spring support 0022, on which there is a spring 0021. Inside the cavity of the spring support 0022, there are two push-button rotating support brackets 0025, on which there is a push-button rotating support 0024. On the push-button rotating support 0024, there is a push-button 0023. The left end of the push-button 0023 is fastened inside the spring 0021, and the right end has a claw structure. The push-button 0023 can be rotated by pressing the push-button rotating support 0024. When it is pressed down, the right end of the push-button 0023 is lifted up, so that it is disengaged from the claw 0011.

[0085] like Figure 4 and Figure 5 As shown, the foaming component 002 has a claw hole 003, a limiting claw hole 004, and a lower support slot 0029. Correspondingly, the decorative panel component 001 has a claw 0011, a limiting claw 0012, and a lower support 0018. During installation, the lower support 0018 is first inserted into the lower support slot 0029, and simultaneously the limiting claw 0012 is inserted into the limiting claw hole 004. The claw 0011 is inserted into the claw hole 003 and simultaneously engages with the push-button 0023 to lock it in place. Furthermore, the decorative panel component 001 has at least one or more claws 0011, and the limiting claw 0012 can be replaced by a claw 0011, and is not limited to the claw 0011 itself.

[0086] like Figure 6 and Figure 7 As shown, on the bracket 0013, there is a surface light source 0015, which includes an LED light panel, a light guide plate, and a diffuser plate, used to provide uniform backlighting. On the surface of the surface light source 0015, there is a film 0016, made of transparent or semi-transparent material, with patterns or text printed on its surface, which can be replaced to achieve different visual effects. On the outermost layer, there is a door panel 0017, made of transparent or semi-transparent material with screen printing, used to organically combine with the pattern of the film 0016 and serve as the final display surface. Specifically, the light emitted by the surface light source passes through the film 0016 to form a specific pattern; users can replace the colored film according to their preferences to achieve different pattern and color effects. Door panel 0017 provides support and protection while enhancing the overall aesthetics. Furthermore, this application is not limited to refrigerator doors; it can also be used for internal refrigerator lighting, refrigerator drawer panels, etc. All solutions applying this principle should be within the scope of this solution's protection.

[0087] In this way, the refrigerator door pattern can be personalized by replacing the colored film, and the pattern can be changed; the colored film can be set to partial or full light transmission, and the lighting effect can be adjusted as needed to obtain a controllable light transmission area; the colored film is organically integrated with the door panel 0017 without affecting the door structure and function, resulting in an integrated structure with the door; low-power LED light source is used, combined with high light transmission materials, to achieve energy saving and environmental protection.

[0088] In summary, it can enhance the aesthetics and technological feel of refrigerator doors; enable personalized customization to meet the aesthetic needs of different users; is easy to operate and has low maintenance costs; and is applicable to various types of refrigerator doors, with broad application prospects.
