[0047] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0048] The following is for reference. Figures 1-8 The present application describes a storage device including a metal inner liner 100, at least two shelf members 200, and a plurality of connecting structures 300.

[0049] It should be noted that the storage devices in the embodiments can be understood as refrigeration and storage devices in a broad sense, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines, etc. Storage devices have diverse structural forms and a wide range of applications. As a specific example, this application embodiment uses a commercial upright freezer as an example for illustration.

[0050] The metal inner liner 100 forms a compartment 101 and a plurality of first mounting holes 102, with the shelf member 200 located within the compartment 101. The material of the metal inner liner 100 includes, but is not limited to, PCM (Phase Change Material), steel, zinc, and aluminum. It should be noted that the size and shape of the compartment 101 and the first mounting holes 102, as well as the number of the first mounting holes 102, can be designed according to actual needs; this embodiment does not impose specific limitations in this regard.

[0051] In this embodiment, the storage device is a commercial upright freezer, meaning that the opening of compartment 101 faces forward to facilitate the display and retrieval of items.

[0052] It is understood that the two shelf components 200 are respectively arranged on the two inner side walls of the compartment 101 to form a shelf group, so as to achieve uniform support for the shelf and thus maximize the use of the internal space of the compartment 101 for classified storage of items. It should be noted that the number and specific distribution of the shelf groups can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0053] In this embodiment, the shelf member 200 extends in the vertical direction, and the item placed on it extends in the horizontal direction.

[0054] The connecting structure 300 corresponds one-to-one with the first mounting hole 102. The connecting structure 300 includes a first connector 310, which is sealed to the first mounting hole 102 and connected to the shelf component 200. The material of the first connector 310 includes, but is not limited to, ABS (Acrylonitrile Butadiene Styrene) or PP (Polypropylene).

[0055] Understandably, compared to the use of screws to connect the metal inner liner 100 and the shelf component 200 in related technologies, the first connector 310 is sealed to the metal inner liner 100 through the first mounting hole 102. This reduces the generation of gaps, allowing the first connector 310 to connect the shelf component 200 and the metal inner liner 100 while reducing the problem of rust on the metal inner liner 100. It also reduces the possibility of foaming material overflowing into the compartment 101 from the first mounting hole 102 during the foaming process after the shelf component 200 is installed on the metal inner liner 100. Simultaneously, by directly connecting the first connector 310 to both the metal inner liner 100 and the shelf component 200, an indirect connection is achieved between the shelf component 200 and the metal inner liner 100. Compared to the direct screw connection in related technologies, this reduces damage to the surface of the metal inner liner 100, effectively isolating the shelf component 200 and the metal inner liner 100, and lowering the possibility of rust on the metal inner liner 100.

[0056] According to the storage device provided in the embodiments of this application, the first connector 310 is sealed to the metal inner liner 100 through the first mounting hole 102, and the first connector 310 is connected to the shelf 200, so that the inner wall of the metal inner liner 100 and the shelf 200 fit tightly, reducing the possibility of rust and overflow of the metal inner liner 100, and improving the product qualification rate and service life.

[0057] In some embodiments, such as Figures 3 to 5 As shown, the storage device also includes multiple flange portions 400, which are disposed on the metal inner liner 100 and correspond one-to-one with the first mounting holes 102. The flange portions 400 extend from the edge of the first mounting holes 102 toward the metal inner liner 100 in a direction away from the shelf member 200, and are engaged with the first connecting member 310. It should be noted that the shape and size of the flange portions 400 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0058] Understandably, the flange 400 protrudes from the side of the metal inner liner 100 away from the shelf member 200. That is, one end of the first connector 310 passes through the first mounting hole 102 and engages with the flange 400, thereby increasing the contact area with the first connector 310, improving the stability and durability of the storage device, and allowing the foaming material to compress the flange 400 during the foaming process, making the first connector 310 and the flange 400 fit more tightly. Simultaneously, since the flange 400 is located at the edge of the first mounting hole 102, it provides insulation and protection for the first mounting hole 102, thus reducing the risk of rust and spillage.

[0059] In some embodiments, such as Figure 3 , Figure 5 and Figure 7 As shown, the length of the flange portion 400 along the axis of the first mounting hole 102 is between 1 and 3 mm to ensure that the contact area between the first connector 310 and the flange portion 400 is as large as possible.

[0060] In this embodiment, the length of the flange portion 400 along the axis of the first mounting hole 102 is 2mm.

[0061] In some embodiments, such as Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the outer wall of the first connector 310 is provided with at least one sealing part 3102, and the inner wall of the flange 400 abuts against the outer wall of the sealing part 3102. It should be noted that the number, shape and size of the sealing parts 3102 can be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0062] Understandably, when the first connector 310 passes through the first mounting hole 102 from the side of the metal inner liner 100 near the shelf member 200, the outer wall of the sealing part 3102 and the inner wall of the flange part 400 abut against each other, ensuring the stability of the connection between the first connector 310 and the metal inner liner 100, and forming a sealed fit, reducing the possibility of foam material entering the first mounting hole 102 from the flange part 400.

[0063] In some embodiments, multiple sealing portions 3102 may be provided, and the multiple sealing portions 3102 are spaced apart along the extending direction of the flange portion 400 to increase the contact area between the first connector 310 and the flange portion 400, thereby improving the connection strength and sealing performance. It should be noted that "multiple" includes two or more.

[0064] In some embodiments, the length of the sealing portion 3102 along the extending direction of the flange portion 400 is in the range of 0.1 to 0.3 mm; the vertical distance between the outer wall of the sealing portion 3102 and the corresponding outer wall of the first connector 310 is in the range of 0.4 to 0.6 mm, so as to ensure a good sealing effect between the sealing portion 3102 and the flange portion 400, while avoiding excessive interference or friction, and ensuring that the first connector 310 has enough space for positioning and fixing during installation.

[0065] In this embodiment, a sealing part 3102 is provided. The length of the sealing part 3102 along the extending direction of the flange part 400 is 0.2 mm, and the vertical distance between the outer wall of the sealing part 3102 and the corresponding outer wall of the first connector 310 is 0.5 mm.

[0066] In some embodiments, such as Figure 3 , Figure 4 , Figures 6 to 8 As shown, at least one guide block 3103 protrudes from the outer wall of the first connector 310. The guide block 3103 is located on the side of the metal inner liner 100 away from the shelf member 200. The outer wall of the guide block 3103 away from the first connector 310 has a guide surface 31031, and the guide surface 31031 is inclined in the direction close to the shelf member 200 towards the direction away from the first mounting hole 102. It should be noted that the size and inclination angle of the guide surface 31031 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0067] Understandably, the guide block 3103 helps guide the first connector 310 to be correctly positioned and assembled during installation, so that the first connector 310 can pass smoothly through the first mounting hole 102 from the side of the metal liner 100 near the shelf member 200 via the inclined guide surface 31031, until the sealing part 3102 abuts against the flange part 400. At this time, the guide block 3103 is located on the side of the flange part 400 away from the shelf member 200. The protruding guide block 3103 and guide surface 31031 can also reduce the first connector 310 from passing through the first mounting hole 102 in the opposite direction, thereby improving the stability of the connection between the first connector 310 and the metal liner 100.

[0068] In some embodiments, such as Figure 3 , Figure 4 , Figures 6 to 8 As shown, multiple guide blocks 3103 are provided, spaced apart around the first connector 310 to improve the accuracy and convenience of installing the first mounting component, and also to help ensure the sealing and stability between the first connector 310 and the metal inner liner 100. It should be noted that the number and specific distribution of the guide blocks 3103 can be designed according to actual needs, and this embodiment does not impose specific limitations in this regard.

[0069] In some embodiments, such as Figures 4 to 8 As shown, at least one of the cross-sections of the first connector 310 and the flange 400 is oval.

[0070] Understandably, the oval cross-section of the first connector 310 provides a larger contact area with the inner wall of the flange 400, which not only distributes the load evenly, reduces stress concentration, increases the torsional resistance of the first connector 310, and improves the durability and reliability of the connection structure 300, but also reduces the possibility of the first connector 310 rotating relative to the first mounting hole 102 based on its oval shape, thereby increasing the stability of the connection structure 300.

[0071] Similarly, the flange portion 400 with an oval cross-section provides more contact points with the inner wall portion of the first connector 310, which can not only distribute the load evenly, reduce stress concentration, increase the torsional resistance of the first connector 310, and improve the durability and reliability of the first connector 310, but also use these contact points as anti-rotation support points, reducing the possibility of the first connector 310 rotating relative to the first mounting hole 102, and increasing the stability of the connection structure 300.

[0072] In this embodiment, the cross-section of the first connector 310 and the cross-section of the flange 400 are both oval. Similarly, since the flange 400 is located at the edge of the first mounting hole 102, the first mounting hole 102 is also oval.

[0073] In some other embodiments, at least one of the cross-sections of the first connector 310 and the flange 400 is N-sided, and N = 2n, where n is a natural number greater than or equal to 1.

[0074] Understandably, the first connector 310 with an N-sided cross-section provides more contact points with the inner wall of the flange 400. This not only distributes the load more evenly, reducing stress concentration and improving the durability and reliability of the first connector 310, but also allows these contact points to serve as anti-rotation support points, reducing the possibility of the first connector 310 rotating relative to the first mounting hole 102 and increasing the stability of the connection structure 300. Simultaneously, since the number of sides of the N-sided shape is even, it also facilitates positioning and guiding during automated feeding, improving the stability, flexibility, and efficiency of the feeding process.

[0075] Similarly, the flange portion 400 with an N-sided cross-section provides more contact points with the outer wall portion of the first connector 310, which can not only distribute the load evenly, reduce stress concentration, and improve the durability and reliability of the first connector 310, but also use these contact points as anti-rotation support points, reducing the possibility of the first connector 310 rotating relative to the first mounting hole 102 and increasing the stability of the connection structure 300.

[0076] In some embodiments, such as Figures 6 to 8 As shown, the first connector 310 includes a main body 311 and a connecting part 312. The main body 311 is partially sealed to the first mounting hole 102. The connecting part 312 is disposed on the side of the main body 311 near the shelf member 200. The outer diameter of the connecting part 312 is larger than the inner diameter of the first mounting hole 102, so that the connecting part 312 abuts against the side of the metal inner liner 100 near the shelf member 200.

[0077] Understandably, one end of the main body 311 is sealed to the metal inner liner 100 via a flange 400 and extends outward from the flange 400 on the side away from the shelf member 200. The outer diameter of the connecting portion 312 is larger than the inner diameter of the first mounting hole 102 to abut against the side of the metal inner liner 100 near the shelf member 200, which helps to provide additional support and stability and reduces the possibility of spillage from the first mounting hole 102 into the compartment 101.

[0078] In some embodiments, such as Figures 6 to 8As shown, the sealing part 3102 and the guide block 3103 are spaced apart on the main body 311 along the extending direction of the flange 400. That is, during the process of the first connecting member 310 being installed from the side of the metal liner 100 near the shelf member 200 to the metal liner 100, the main body 311 is squeezed and cooperates with the guide block 3103 to smoothly pass through the first mounting hole 102 until the sealing part 3102 abuts against the flange 400. At this time, the guide block 3103 is located on the side of the flange 400 away from the shelf member 200, and the connecting part 312 abuts against the side of the metal liner 100 near the shelf member 200.

[0079] In some embodiments, such as Figure 3 and Figure 4 As shown, the first connector 310 is detachably connected to the shelf 200 to facilitate maintenance or replacement of the shelf 200 and to adapt to different storage needs.

[0080] In some embodiments, such as Figures 2 to 4 , Figure 7 and Figure 8 As shown, one of the first connector 310 and the shelf member 200 forms a slot, and the other of the first connector 310 and the shelf member 200 is provided with a buckle 202 that cooperates with the slot.

[0081] It is understandable that one of the first connector 310 and the shelf member 200 forms a slot, and the other is provided with a buckle 202. The first connector 310 and the shelf member 200 are detachably connected through the cooperation of the slot and the buckle 202, so as to achieve the firmness of the connection and the convenience of disassembly.

[0082] In some embodiments, such as Figures 2 to 4 , Figure 7 and Figure 8 As shown, when the slot is formed in the first connector 310, the slot includes two connecting grooves 3104 and 3105 spaced apart along the length of the shelf member 200. The opening of the first connecting groove 3104 faces the shelf member 200, and the first connecting groove 3104 and the second connecting groove 3105 are connected but their openings face opposite directions. One end of the buckle 202 is connected to the shelf member 200, and the other end extends through the opening of the first connecting groove 3104 into the second connecting groove 3105. It should be noted that the shape and size of the first connecting groove 3104 and the second connecting groove 3105 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0083] It is understood that the opening of the first connecting groove 3104 faces the shelf member 200, and the opening of the second connecting groove 3105 faces away from the shelf member 200. The first connecting groove 3104 and the second connecting groove 3105 are spaced apart, so that the shelf member 200 can slide along the length direction of the shelf member 200 so that the buckle 202 can slide smoothly in the slot until it abuts and engages, thereby realizing the connection and fixation between the shelf member 200 and the first connecting member 310.

[0084] Furthermore, when the buckle 202 abuts against the slot, a portion of the surface of the buckle 202 covers the opening of the first connecting groove 3104, while the other portion abuts against the wall of the second connecting groove 3105. This reduces the possibility of the foaming material flowing through the opening of the second connecting groove 3105, sequentially passing through the second connecting groove 3105 and the first connecting groove 3104, and then flowing into the compartment 101 from the opening of the first connecting groove 3104, thus improving the sealing performance of the connection between the shelf component 200 and the first connecting component 310. Simultaneously, the curing of the foaming material can also enhance the stability of the connection between the shelf component 200 and the first connecting component 310.

[0085] In some embodiments, such as Figure 7 and Figure 8 As shown, the first connecting groove 3104 passes through the connecting portion 312 and extends into the main body portion 311, and the second connecting groove 3105 passes through the main body portion 311 and extends into the connecting portion 312.

[0086] In some embodiments, such as Figure 3 and Figure 4 As shown, the shelf member 200 extends vertically, and the end of the buckle 202 away from the shelf member 200 extends downward. The first connecting groove 3104 is disposed above the second connecting groove 3105 to improve the stability of the connection between the two by utilizing the weight of the shelf member 200 itself. Of course, in other embodiments, the end of the buckle 202 away from the shelf member 200 may extend upward, and the first connecting groove 3104 may be disposed below the second connecting groove 3105. This embodiment does not impose specific limitations on this.

[0087] In some embodiments, such as Figure 2 and Figure 3 As shown, the shelf member 200 forms a relief groove 203, the inner wall of the relief groove 203 abuts against the outer wall of the connecting part 312, and the surface portion of the shelf member 200 located at the edge of the groove of the relief groove 203 abuts against the metal inner liner 100. It should be noted that the shape and size of the relief groove 203 can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0088] Understandably, considering that the connecting part 312 protrudes from the side of the metal inner liner 100 near the shelf member 200, by making the shelf member 200 form a relief groove 203 with the groove facing the metal inner liner 100, and the relief groove 203 extending along the length of the shelf member 200, the shelf member 200 and the first connecting member 310 are engaged, while the inner wall of the relief groove 203 and the outer wall of the connecting part 312 abut against each other, and the surface of the shelf member 200 located at the edge of the groove of the relief groove 203 abuts against the metal inner liner 100, it helps to make the structure of the storage equipment more compact, while enhancing the stability and sealing of the connection between the shelf member 200, the metal inner liner 100 and the first connecting member 310, and reducing the possibility of overflow and rusting of the metal inner liner 100.

[0089] In some embodiments, such as Figures 2 to 4 and Figure 7 As shown, the shelf member 200 is located within the compartment 101 and forms a second mounting hole 201. The first connector 310 forms a third mounting hole 3101. The connecting structure 300 also includes a second connector (not shown), one end of which passes through the second mounting hole 201 and mates with the third mounting hole 3101. The connection between the first connector 310 and the second connector includes, but is not limited to, a threaded connection. The material of the shelf member 200 includes, but is not limited to, stainless steel. The material of the second connector includes, but is not limited to, aluminum alloy or zinc alloy. It should be noted that the size and shape of the second mounting hole 201 and the third mounting hole 3101, as well as the number of the second mounting holes 201, can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0090] Understandably, the second connector, through the third mounting hole 3101, enables a detachable connection between the first connector 310 and the shelf component 200, while simultaneously ensuring a tight fit between the inner wall of the metal liner 100 and the shelf component 200. This reduces the possibility of foaming material overflowing into the compartment 101 from the first mounting hole 102 during the foaming process after the shelf component 200 is installed in the metal liner 100. Simultaneously, the direct connection between the first connector 310 and the second connector achieves an indirect connection between the shelf component 200 and the metal liner 100. This differs from the related art where screws are directly used to connect the metal liner 100 and the shelf component 200, reducing damage to the liner surface and isolating the second connector from the metal liner 100, thus lowering the possibility of rust on the metal liner 100.

[0091] In this embodiment, as Figures 2 to 4 , Figure 7 and Figure 8As shown, the first connector 310 forms a slot and a third mounting hole 3101 to increase the contact area with the shelf member 200 and improve the flexibility and stability of assembly. Of course, in other embodiments, the first connector 310 may only have one of the slot, the buckle 202 and the third mounting hole 3101, and this embodiment does not impose specific limitations on this.

[0092] In some embodiments, such as Figure 2 As shown, the shelf component 200 is provided with a plurality of second mounting holes 201 at intervals along its length, which improves the stability of the connection between the metal inner liner 100 and the shelf component 200 and enhances the support force on the shelf. It should be noted that the number of second mounting holes 201 can be designed according to actual needs, and this embodiment does not impose a specific limitation on this.

[0093] It is understood that the sum of the number of second mounting holes 201 of all shelf components 200, the number of connecting structures 300, and the number of first mounting holes 102 are equal. It should be noted that "multiple" includes two or more.

[0094] In some embodiments, such as Figure 4 As shown, the third mounting hole 3101 passes through the connecting part 312 and extends to the main body part 311, thereby increasing the contact area between the second connector and the first connector 310 and improving the overall stability and reliability of the connecting structure 300.

[0095] In some embodiments, such as Figure 4 As shown, the third mounting hole 3101 is a blind hole.

[0096] Understandably, the third mounting hole 3101 only penetrates the connecting part 312, thereby reducing the gap formed at the third mounting hole 3101 when installing the second connecting part, reducing the risk of foam material overflowing from the third mounting hole 3101, improving the sealing performance between the shelf part 200 and the metal inner liner 100, reducing cold air leakage, and improving the energy efficiency of the storage equipment.

[0097] In some embodiments, such as Figure 4 As shown, the diameter of the third mounting hole 3101 gradually increases along the direction close to the shelf member 200.

[0098] It is understandable that the diameter of the third mounting hole 3101 near the main body 311 is smaller than the diameter of the third mounting hole 3101 near the connecting part 312, thereby reducing the friction and resistance during the installation of the first connector 310 and improving the tightness and stability of the connection between the shelf 200 and the metal liner 100.

[0099] For example, the taper of the third mounting hole 3101 is 1°.

[0100] In this embodiment, as Figure 4 As shown, the third mounting hole 3101 is a tapered blind hole, that is, the longitudinal section of the third mounting hole 3101 is trapezoidal.

[0101] In some embodiments, the second connector is a self-tapping screw.

[0102] Understandably, self-tapping screws, compared to ordinary screws, can directly form their own threads on the first connector 310 during installation, eliminating the need for pre-tapping the first connector 310. This speeds up the manufacturing and installation process, improving efficiency. It also reduces the need for additional fasteners such as nuts and washers, simplifying the entire connection structure 300 and reducing assembly complexity.

[0103] In some embodiments, such as Figure 1 As shown, the metal inner liner 100 is assembled from multiple sheet metal parts. These sheet metal parts include, but are not limited to, PCM sheets, hot-dip galvanized powder-coated sheets, or aluminum sheets. It should be noted that the number and shape of the sheet metal parts can be designed according to actual needs; this embodiment does not impose specific limitations in this regard.

[0104] Understandably, sheet metal parts can be produced using standardized processing techniques, such as cutting, stamping, and bending, making the manufacturing process of the metal inner liner 100 more efficient and controllable. At the same time, the splicing design makes the assembly process more flexible and facilitates mass production. Compared to a one-piece molded metal inner liner 100, the metal inner liner 100 formed by splicing multiple sheet metal parts has lower manufacturing and maintenance costs, is easier to transport and store, and offers greater flexibility.
