Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a padding structure. Background Technology

[0002] During the production, transportation, and storage of refrigerators, it is necessary to use padding structures to fix and protect the glass or plastic shelves inside the refrigerator to prevent them from shaking or colliding.

[0003] In related technologies, pre-foamed EPS (Expanded Polystyrene) block components are used as padding structures. During use, they are placed between shelves or between shelves and the inner liner, and the elasticity of the foam material is used to achieve cushioning and fixation.

[0004] However, the pre-formed block components are bulky, resulting in high space occupancy and high costs in transportation and storage. Furthermore, the foam structure is prone to damage when stacked under pressure, affecting its protective performance. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a padding structure.

[0006] This application provides a padding structure for use in refrigeration equipment. The refrigeration equipment includes a cabinet and a shelf, with the shelf disposed in the cabinet. The padding structure is used to support the shelf in the cabinet. The padding structure includes a body, which includes a socket, a first locking part, and a second locking part. The body has a first state and a second state. In the first state, the body is plate-shaped. The body switches to the second state by bending. In the second state, the body is column-shaped, and the socket is used to insert the shelf. The first locking part and the second locking part are used to lock the body in the second state by connection.

[0007] When the padding structure is in the first state, its flat shape allows multiple padding structures to be stacked tightly. Compared with the block components in related technologies, the flat padding structure has a relatively high volume compression rate, thereby increasing the storage capacity per unit volume. More padding structures can be stored without changing the storage space, thus solving the technical problem of high storage costs in related technologies.

[0008] When the padding structure is in the second state, compared with the block structure in related technologies, its columnar shape can bear a larger force in the axial direction, and the support direction of the padding structure for the shelf is concentrated in this axial direction. Therefore, the possibility of irreversible deformation of the columnar padding structure is relatively low. It can provide effective support for the shelf during production, storage and transportation, thereby solving the technical problem of poor support reliability in related technologies.

[0009] Based on this, the first locking part and the second locking part can maintain the shape of the body by connecting them, reducing the probability of the body falling apart when under load, thereby further improving the reliability and stability of the padding structure for supporting the shelf.

[0010] In summary, this application achieves the technical effect of reducing warehousing costs and enhancing the protection performance of shelving by designing a body with a convertible form and setting a first locking part and a second locking part on the body that can interlock.

[0011] In some embodiments, the body further includes a buckle and a latch, the buckle forming a first locking part and the latch forming a second locking part, and the buckle and the latch engaging.

[0012] By incorporating snap-fit ​​and latches, the stability of the main body in its second state is enhanced, thereby improving the reliability of the padding structure's support for the shelf. Furthermore, the snap-fit ​​and latches can be unlocked by applying a reverse force, enabling non-destructive disassembly and allowing the padding structure to be reused, thus reducing the cost of shelf support.

[0013] In some embodiments, the buckle and the body are an integral structure, and the buckle can be bent relative to the body.

[0014] Compared to designing the buckle as a separate component, integrating the buckle with the main body simplifies the manufacturing process of the mounting structure, achieving the technical effect of reducing process complexity and production costs. Furthermore, by designing the buckle to bend relative to the main body, it gains freedom of movement during installation, specifically allowing it to self-adjust within a certain range to adapt to the position of the locking mechanism. This ensures a smooth and reliable engagement between the buckle and the locking mechanism, thereby reducing operational difficulty.

[0015] In some embodiments, the body further includes at least two folds, and the body switches to a second state by folding along the folds.

[0016] The folding section defines the number of bends, the angle of bends, and the area of ​​bends on the main body, thereby ensuring that the structural shape formed by each pad structure after being manually folded by the operator has a high degree of consistency. This allows each pad structure to provide support with a preset, uniform shape and size, thereby achieving the technical effect of improving the support stability and reliability of the pad structure.

[0017] In some embodiments, in the second state, the body is prismatic.

[0018] Compared to the irregular shape or loose structure of EPS block components in related technologies, the prism-shaped structure formed by folding has a definite and consistent shape, thereby ensuring that each pad structure can provide reliable support for the shelf, thus achieving the technical effect of improving support reliability.

[0019] In some embodiments, in a first state, the body is a rectangular plate, the body includes three folds extending in the length direction of the body, and the three folds are distributed in the width direction of the body; wherein, in the width direction of the body, the folds are distributed between the first locking part and the second locking part, and at least one fold is distributed on the socket.

[0020] By distributing three folding portions along the width of the body between the first locking portion and the second locking portion, when the body is bent along the folding portions, the first folding area carrying the first locking portion and the fourth folding area carrying the second locking portion can approach each other through the folding movement and eventually overlap together, thereby providing convenient conditions for the connection of the first locking portion and the second locking portion, and thus achieving the technical effect of reducing the difficulty of operation.

[0021] Meanwhile, by ensuring that the upper portion of the socket has at least one fold, it can be ensured that the socket can form a slot with an angle after folding. Compared with the solution of inserting the socket directly into the shelf without folding, the folded socket can provide three-dimensional support for the shelf, preventing the shelf from flipping in the socket, thereby achieving the technical effect of improving shelf stability and reducing shelf wear.

[0022] In some embodiments, at least one end of the body includes a notch in the length direction of the body, and one end of the fold extends to the notch.

[0023] By guiding the end of the folded part to the notch, a local, unobstructed bending guide area can be provided for the folded part, thereby reducing bending resistance, allowing the material in the folded part area to deform more freely, reducing the force required for bending, reducing the probability of incomplete bending or jamming, making the folding action of the body smoother and less strenuous, and thus improving the convenience of folding operation, reducing the difficulty of folding operation, and improving the consistency of the shape in the second state.

[0024] In some embodiments, the body is corrugated cardboard, and the folds include at least one of indentation, cut, and micro-perforation.

[0025] Corrugated paper is biodegradable. Compared with the related technologies that use EPS material to prepare padding structures, this embodiment can solve the technical problems of high environmental pollution and poor environmental protection in the related technologies.

[0026] Furthermore, corrugated paper is recyclable and easy to process, which helps reduce production costs.

[0027] By using the above-mentioned process to form the folded part, the main body can be accurately and effortlessly transformed from the first state to the second state, thereby reducing the difficulty of folding the main body and improving the user experience for operators.

[0028] In some embodiments, the body further includes a slot, which is located at the end of the body in a second state.

[0029] During installation, the corresponding parts of the shelf can be embedded or snapped into the slot, so that both ends of the padding structure can have the function of positioning the shelf, thus expanding the applicable scenarios of the padding structure.

[0030] Meanwhile, the surface of the inner liner of the box may have reinforcing ribs, screw heads or other protruding structures. The contour of the slot is designed to avoid these protruding structures, ensuring that the padding structure can fit tightly with the inner liner of the box and guarantee the effective transmission of support force.

[0031] In some embodiments, a protective film is also included, disposed on the surface of the body, the protective film being used to contact the inner wall of the housing.

[0032] By setting a protective film, a smooth and dense physical isolation layer is formed between the padding structure and the inner wall of the cabinet. This allows the relatively smooth protective film to replace the main body in contact with the inner wall of the cabinet, thereby reducing the risk of scratching the cabinet. This achieves the technical effects of improving the practicality of the padding structure, reducing shelf friction loss, and improving the yield rate of refrigeration equipment.

[0037] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0039] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In related technologies, pre-foamed EPS block components are commonly used as padding structures. This solution reduces the probability of damage to the shelves and the inner liner of the box due to collision by inserting EPS block components of a specific shape between two adjacent shelves or between the shelf and the inner liner of the box, thereby achieving buffering and fixing of the shelves.

[0043] However, to achieve the fixing and cushioning functions of EPS block components, they need to be prefabricated into a three-dimensional structure with a specific shape. Once formed, this three-dimensional structure cannot be changed, resulting in a large volume and high space occupation during transportation and warehousing, thus increasing logistics and warehousing costs. In addition, the structural strength of EPS block components is limited, making them prone to breakage or irreversible deformation during transportation, stacking, and handling, which compromises their protective performance and fails to provide reliable support for shelving.

[0044] It is evident that the aforementioned technologies suffer from high warehousing costs and poor support reliability.

[0045] To solve the above-mentioned technical problems, this application combines Figures 1 to 10 A padding structure 100 is proposed.

[0046] like Figure 1 , Figure 2 and Figure 10As shown, the padding structure 100 provided in this embodiment is used for a refrigeration device 200. The refrigeration device 200 includes a housing 210 and a shelf 220. The shelf 220 is disposed in the housing 210. The padding structure 100 is used to support the shelf 220 in the housing 210. The padding structure 100 includes a body 110. The body 110 includes an insertion port 111, a first locking part 112, and a second locking part 113. The body 110 has a first state and a second state. In the first state, the body 110 is plate-shaped. The body 110 switches to the second state by bending. In the second state, the body 110 is column-shaped. The insertion port 111 is used to insert the shelf 220. The first locking part 112 and the second locking part 113 are used to lock the body 110 in the second state by connection.

[0047] The refrigeration equipment 200 includes refrigerators, freezers, vending machines with refrigeration functions, etc. This application does not impose a rigid limitation on the product type of the refrigeration equipment 200, as long as it has the support and positioning requirements of shelves 220.

[0048] The cabinet 210 is the external frame of the refrigeration equipment 200. The interior of the cabinet 210 encloses a refrigeration space, and items that need to be refrigerated are placed inside the cabinet 210.

[0049] Shelves 220 refer to the internal space partitioning structure of the refrigeration equipment 200, including glass partitions or plastic partitions. Shelves 220 can divide the cabinet 210 into multiple storage spaces to achieve partitioned storage.

[0050] The padding structure 100 proposed in this application is installed in the housing 210 to position and support the shelves 220 inside the housing 210 during the production, transportation and storage of the refrigeration equipment 200, so as to avoid collision damage to adjacent shelves 220 or collision damage between shelves 220 and the inner liner of housing 210.

[0051] The main body 110 is the main part of the padding structure 100. The socket 111 is an opening provided on the main body 110, and its shape and size are designed to accommodate and lock the edge or specific part of the refrigerator shelf 220. The first locking part 112 and the second locking part 113 are a set of interlocking structures provided in different parts of the main body 110, and they achieve mechanical interlocking by connecting with each other.

[0052] The first state corresponds to the transportation and storage scenarios, in which the main body 110 is an unfolded flat plate. The second state corresponds to the usage scenario where it is installed in the housing 210, in which the main body 110 has formed a stable columnar structure through bending.

[0053] Based on this, the main body 110 is formed from a single sheet and can be folded through material design or pre-cutting and creasing treatment. During transportation and storage, the main body 110 remains in its first state, namely, flat.

[0054] When installation is required, the operator bends the main body 110, transforming it from a flat plate in the first state to a columnar structure in the second state. This columnar structure provides stable support for the shelf 220. During the bending process, the first locking part 112 and the second locking part 113 located on the main body 110 approach and engage with each other. When the main body 110 is bent to the second state, the first locking part 112 and the second locking part 113 connect together to form a mechanical interlock, locking the main body 110 in the second state, preventing it from spreading out, and ensuring the stability of the support.

[0055] When the main body 110 is in the second state, the slot 111 provided thereon is used to insert the refrigerator shelf 220. The outline of the slot 111 is designed to match the edge or specific part of the shelf 220, thereby securing the shelf 220. In the second state, the padding structure 100 is placed between the shelf 220 and the inner liner of the cabinet 210, with one end or side of its columnar structure contacting the inner liner of the cabinet 210. When the door of the refrigeration unit 200 is closed, the pressure exerted by the door on the padding structure 100 is transmitted to the shelf 220, thereby pressing and fixing the shelf 220 inside the cabinet 210, preventing the shelf 220 from shaking or colliding during transportation.

[0056] When the padding structure 100 is in the first state, its flat shape allows multiple padding structures 100 to be stacked tightly. Compared with the block-shaped components in related technologies, the flat padding structure 100 has a relatively high volume compression rate, thereby increasing the storage capacity per unit volume. More padding structures 100 can be stored without changing the storage space, thus solving the technical problem of high storage costs in related technologies.

[0057] When the padding structure 100 is in the second state, compared with the block structure in the related technology, its columnar shape can bear a larger force in the axial direction, and the support direction of the padding structure 100 on the shelf 220 is concentrated in this axial direction. Therefore, the possibility of irreversible deformation of the columnar padding structure 100 is relatively low. It can provide effective support for the shelf 220 during production, storage and transportation, thereby solving the technical problem of poor support reliability in the related technology.

[0058] Based on this, the first locking part 112 and the second locking part 113 can maintain the shape of the body 110 by connecting them, reducing the probability of the body 110 falling apart when bearing load, thereby further improving the reliability and stability of the padding structure 100 supporting the shelf 220.

[0059] In summary, this application achieves the technical effect of reducing storage costs and enhancing the protection performance of the shelf 220 by designing a body 110 with a convertible form and providing a first locking part 112 and a second locking part 113 on the body 110 that can be interlocked.

[0060] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of this application, the body 110 further includes a buckle 1121 and a latch 1131, the buckle 1121 forming a first locking part 112, the latch 1131 forming a second locking part 113, and the buckle 1121 and the latch 1131 engaging.

[0061] The buckle 1121 is a protrusion or hook-shaped structure with a specific shape set on the plate of the body 110, and the latch 1131 is a hole, groove or recess structure that matches the shape of the buckle 1121 and is set on another position of the body 110.

[0062] During the bending process of the body 110 from a flat plate shape in the first state to a cylindrical shape in the second state, the area with the latch 1121 and the area with the slot 1131 gradually approach each other. When the bending action causes the body 110 to reach the shape corresponding to the second state, the latch 1121 can be engaged with the slot 1131 through its elasticity or through a specific movement trajectory, thus achieving the engagement between the two. The engagement between the latch 1121 and the slot 1131 creates a mechanical constraint, which prevents the two areas that have approached each other from separating, overcomes the force of the body 110 returning to the first state, and thus maintains the body 110 in the second state.

[0063] Therefore, by setting the buckle 1121 and the latch 1131, the stability of the body 110 in the second state is improved, achieving the technical effect of improving the support reliability of the padding structure 100 for the shelf 220. Furthermore, the snap-fit ​​of the buckle 1121 and the latch 1131 can be unlocked by applying a reverse force, achieving non-destructive disassembly and allowing the padding structure 100 to be reused, thereby reducing the support cost of the shelf 220.

[0064] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of this application, the buckle 1121 and the body 110 are an integral structure, and the buckle 1121 can be bent relative to the body 110.

[0065] The buckle 1121 is integrally formed on the body 110. Specifically, the buckle 1121 is formed by cutting and embossing on the body 110. The buckle 1121 is cut out as part of the body 110, but its root is still connected to the body 110. Its movable boundary is defined by the embossing line, so that the buckle 1121 can be bent along the embossing line at its root when the locking function needs to be performed.

[0066] Compared to designing the buckle 1121 as a separate component, integrating the buckle 1121 with the body 110 simplifies the manufacturing process of the mounting structure 100, achieving the technical effect of reducing process complexity and production costs. Furthermore, by designing the buckle 1121 to bend relative to the body 110, the buckle 1121 has a degree of freedom of movement during installation, specifically, it can self-adjust within a certain range to adapt to the position of the latch 1131, ensuring that the buckle 1121 and the latch 1131 can smoothly and reliably complete the engagement action, thereby reducing the technical effect of operational difficulty.

[0067] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of this application, the body 110 further includes at least two folds 114, and the body 110 switches to a second state by folding along the folds 114.

[0068] The folding portion 114 is a linear structure pre-machined on the body 110 sheet material to guide and define the bending position. Specifically, at least two folding portions 114 divide a single sheet material into multiple folding areas. When it is necessary to change the body 110 from a first state to a second state, the operator bends along the folding portion 114.

[0069] The folding part 114 defines the number of bends, the bend angle, and the bend area on the body 110, thereby ensuring that the structural shape formed by each pad structure 100 after being manually folded by the operator has a high degree of consistency, so that each pad structure 100 can provide support with a preset, uniform shape and size, thereby achieving the technical effect of improving the support stability and reliability of the pad structure 100.

[0070] like Figure 2 , Figure 3 and Figure 5 As shown in some embodiments of this application, in the second state, the body 110 is prismatic.

[0071] After the main body 110 is folded along at least two folds 114, its shape is prismatic, including but not limited to triangular prisms, quadrangular prisms, etc.

[0072] The prismatic structure has strong stability. When its axial direction is consistent with the direction of the supporting force, it can distribute the pressure evenly on its edges and sides, so that the padding structure 100 can withstand the weight of the shelf 220 in the second state, thereby providing stable support for the shelf 220.

[0073] Compared to the irregular shape or loose structure of EPS block components in related technologies, the prism-shaped structure formed by folding has a definite and consistent shape, thereby ensuring that each pad structure 100 can provide reliable support for the shelf 220, thus achieving the technical effect of improving support reliability.

[0074] like Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments of this application, in a first state, the body 110 is a rectangular plate, and the body 110 includes three folded portions 114. The folded portions 114 extend in the length direction of the body 110, and the three folded portions 114 are distributed in the width direction of the body 110. In the width direction of the body 110, the folded portions 114 are distributed between the first locking portion 112 and the second locking portion 113, and at least one folded portion 114 is distributed on the socket 111.

[0075] The rectangular plate defines the shape of the body 110 during transportation and storage, and has a defined length and width direction. The folded portion 114 extends along the length direction of the body 110, meaning the indentation line or cutting line is a parallel line set along the long side of the rectangular plate. The three folded portions 114 distributed along the width direction mean that these three parallel folded portions 114 divide the rectangular plate into four continuous folded areas along its width.

[0076] Among them, with Figure 1 Taking this as an example, the main body 110 is divided into a first folded region, a second folded region, a third folded region, and a fourth folded region from left to right. After folding, the first and fourth folded regions overlap to form one sidewall of the triangular prism. The second and third folded regions form the other two sidewalls. Therefore, the cross-section of the main body 110 in the second form is triangular. A triangular cross-section structure possesses strong structural stability. Compared to designs with quadrilateral or pentagonal cross-sections, the triangular cross-section of the main body 110 has higher structural strength and a relatively lower possibility of uncontrollable deformation during support, thus achieving the technical effect of improving support stability and reliability.

[0077] Furthermore, under the combined action of the three folding parts 114, the rectangular plate can be bent sequentially to ensure that the body 110 with a triangular cross-section is finally formed. This makes the folding process of the body 110 repeatable and consistent, ensuring that any operator can complete the same folding operation according to the preset folding parts 114. This reduces the impact of the uncontrollable characteristics of manual operation on the second form, reduces the risk of shelf 220 fixing failure due to shape deviation of individual padding structures 100, and thus achieves the technical effect of unifying the form in the second state and improving the support accuracy.

[0078] Based on this, by distributing three folding portions 114 along the width direction of the body 110 between the first locking portion 112 and the second locking portion 113, when the body 110 is bent along the folding portions 114, the first folding area carrying the first locking portion 112 and the fourth folding area carrying the second locking portion 113 can approach each other through the folding movement and eventually overlap together, thereby providing convenient conditions for the connection of the first locking portion 112 and the second locking portion 113, and thus achieving the technical effect of reducing the difficulty of operation.

[0079] Meanwhile, by ensuring that the socket 111 has at least one folded portion 114, it can be ensured that the socket 111 can form a slot with an angle after folding. Taking one folded portion 114 in the socket 111 and two other folded portions 114 distributed on the left and right sides of the socket 111 as an example, the folded socket 111 is V-shaped. Compared with the solution of directly inserting the unfolded socket 111 into the shelf 220, the folded socket 111 can provide three-dimensional support for the shelf 220, preventing the shelf 220 from flipping in the socket 111, thereby achieving the technical effect of improving the stability of the shelf 220 and reducing the wear and tear of the shelf 220.

[0080] like Figure 1 and Figure 7 As shown, in some embodiments of this application, at least one end of the body 110 includes a notch 115 in the length direction of the body 110, and one end of the fold 114 extends to the notch 115.

[0081] The notch 115 is a structure formed by cutting the edge of the body 110 plate, specifically a V-shaped notch. The folded portion 114 provided on the body 110 extends to and terminates at the notch 115. This structural feature is applicable to any one or more folded portions 114, and the notch 115 can be provided at any end or both ends in the length direction of the body 110.

[0082] When an operator bends the body 110 along the fold 114, the inner and outer layers of the body 110 will be stretched and compressed at the fold 114. The material will experience significant bending resistance due to stress concentration and the restraint from surrounding unbent material. By guiding the end of the fold 114 to the notch 115, a localized, unobstructed bending guide area can be provided for the fold 114, thereby reducing bending resistance. This allows the material in the fold 114 area to deform more freely, reducing the force required for bending and decreasing the probability of incomplete bending or jamming. This makes the folding action of the body 110 smoother and less strenuous, ultimately improving the convenience of the folding operation, reducing the difficulty of the folding operation, and enhancing the consistency of the form in the second state.

[0083] In some embodiments of this application, the body 110 is corrugated cardboard, and the fold 114 includes at least one of indentation, cut, and micro-perforation.

[0084] Corrugated paper is a biodegradable material. Compared with the related technology that uses EPS material to prepare padding structure 100, this embodiment can solve the technical problems of high environmental pollution and poor environmental protection in the related technology.

[0085] Furthermore, corrugated paper is recyclable and easy to process, which helps reduce production costs.

[0086] Building on this, indentation is a process that uses a mold to apply pressure to the surface of corrugated cardboard, causing some of its fiber structure to be crushed, thus creating a groove line that is easy to bend. This process does not cut the material.

[0087] A slit is an incomplete cut made on the surface of corrugated cardboard, severing the surface fibers but preserving some continuity of the bottom or middle layer material, thus forming a line that guides the bend.

[0088] A microperforated line is a dotted line formed by densely packed tiny holes on corrugated cardboard. These holes weaken the structural strength of the board at that point, making it easy to bend along the line.

[0089] The above processing methods are all applicable to corrugated cardboard, used to form preset structural weakening lines on the corrugated cardboard, thereby forming the fold portion 114 that controls the folding accuracy. By using these processes to form the fold portion 114, the body 110 can be accurately and effortlessly transformed from the first state to the second state, thereby reducing the difficulty of folding the body 110 and improving the user experience for operators.

[0090] like Figure 1 As shown, in some embodiments of this application, the body 110 also includes a slot 116, which is located at the end of the body 110 in a second state.

[0091] The slot 116 is a recess or cut made on the edge of the body 110 plate.

[0092] When the main body 110 is in the second state, the slot 116 is located at its end. The shape and size of the slot 116 are designed to fit the shape of the shelf 220, for example, to match the support edge, protrusion, or metal edging on the shelf 220. During installation, the corresponding part of the shelf 220 can be inserted into or snapped into the slot 116, thereby enabling both ends of the padding structure 100 to position the shelf 220, thus expanding the applicable scenarios of the padding structure 100.

[0093] Meanwhile, the inner surface of the housing 210 may have reinforcing ribs, screw heads, or other protruding structures. The contour of the slot 116 is designed to avoid these protruding structures, preventing interference between the padding structure 100 and these protruding structures after installation. This ensures that the padding structure 100 can fit tightly against the inner surface of the housing 210, guaranteeing effective transmission of support force. Therefore, by setting the slot 116, the adaptability of the padding structure 100 within the housing 210 can be improved, thereby reducing the installation difficulty of the padding structure 100 and improving support accuracy.

[0094] like Figure 9 As shown, in some embodiments of this application, the padding structure 100 further includes a protective film 120 disposed on the surface of the body 110, and the protective film 120 is used to contact the inner wall of the box 210.

[0095] The protective film 120 is a thin layer of polymer material, such as PE (Polyethylene) film or PP (Polypropylene) film, covering the surface of the body 110. Specifically, the protective film 120 is attached to the surface of the body 110 by a coating, lamination, or coating process, and is located at least in the area where the body 110 contacts the inner wall of the housing 210.

[0096] The fibers on the surface of corrugated cardboard can cause scratches on the inner wall of the box 210 under long-term vibration and friction. By setting a protective film 120, a smooth and dense physical isolation layer is formed between the padding structure 100 and the inner wall of the box 210. This allows the relatively smooth protective film 120 to replace the body 110 in contact with the inner wall of the box 210, thereby reducing the risk of scratching the box 210. This improves the practicality of the padding structure 100, reduces the friction loss of the shelf 220, and improves the yield of the refrigeration equipment 200.

[0097] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
