Description

Technical Field

[0001] The present application belongs to the field of refrigeration technology, and in particular relates to a storage device. Background Art

[0002] Commercial refrigerators are commonly found in shopping malls, supermarkets, tourist attractions, convenience stores, and other locations, displaying and selling consumer goods that require low-temperature storage, such as alcoholic beverages. During the assembly of the refrigerator's metal liner and shelf rails, the shelves are typically secured to the liner with screws. This requires pre-punching circular holes in the liner sheet material for the screws to pass through. However, punching these holes damages the liner's protective coating, making it susceptible to rust around the holes. Inadequate sealing between the holes and the screws can also result in material spillage, impacting both product quality and service life. Utility Model Content

[0044] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0045] Reference below Figures 1-8 The storage device provided in an embodiment of the present application is described, and the storage device includes a metal inner container 100 , at least two shelf members 200 and a plurality of connection structures 300 .

[0046] It should be noted that the storage devices in the embodiments can be understood as refrigerated storage devices in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold storage cabinets, and refrigerated vending machines. Storage devices have diverse structural forms and a wide range of applications. As a specific example, a commercial upright freezer is used as a specific example in the embodiments of this application.

[0047] The metal liner 100 forms a compartment 101 and a plurality of first mounting holes 102. Materials for the metal liner 100 include, but are 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 first mounting holes 102, as well as the number of first mounting holes 102, can be designed based on actual needs and are not specifically limited in this embodiment.

[0048] In this embodiment, it is considered that the storage device is a commercial upright refrigerator, that is, the opening of the compartment 101 faces forward to facilitate displaying and taking out items.

[0049] The shelf member 200 is located within the compartment 101 and defines a second mounting hole 201. The shelf member 200 may be made of, but is not limited to, stainless steel. It should be noted that the size and shape of the second mounting hole 201 and the number of the first mounting holes 102 can be designed based on actual needs and are not specifically limited in this embodiment.

[0050] It is understood that the two shelf members 200 are disposed oppositely on the two inner side walls of the compartment 101 to form a shelf group, thereby achieving uniform support for the shelves and maximizing 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 are not specifically limited in this embodiment.

[0051] In this embodiment, the shelf member 200 extends in the up-down direction, and the object storage member extends in the left-right direction.

[0052] The connecting structure 300 corresponds one-to-one to the first mounting hole 102. The connecting structure 300 includes a first connecting member 310 and a second connecting member 320. The first connecting member 310 is arranged in the first mounting hole 102 and is riveted to the metal liner 100. The first connecting member 310 forms a third mounting hole 3101. One end of the second connecting member 320 passes through the second mounting hole 201 and cooperates with the third mounting hole 3101.

[0053] Exemplarily, the first connecting member 310 is a compression rivet.

[0054] It should be noted that the material of the first connecting member 310 includes, but is not limited to, aluminum alloy or zinc alloy. The material of the second connecting member 320 includes, but is not limited to, aluminum alloy or zinc alloy. The connection between the first connecting member 310 and the second connecting member 320 includes, but is not limited to, a threaded connection. It should be noted that the shape and size of the third mounting hole 3101 can be designed according to actual needs and is not specifically limited in this embodiment.

[0055] It can be understood that, on the one hand, compared with the related art of directly connecting the metal liner 100 and the shelf member 200 with screws, the first connecting member 310 and the metal liner 100 are riveted together through the first mounting hole 102, which can make the connection between the metal liner 100 and the first connecting member 310 tighter and reduce the generation of gaps. It can not only withstand large external forces such as tension and shear force, but also reduce the risk of damage and rust to the metal liner 100 due to loosening or falling off of the screws; on the other hand, the second connecting member 320 realizes the connection between the first connecting member 310 and the shelf member 200 through the third mounting hole 3101, while making the inner side wall of the metal liner 100 and the shelf member 200 fit tightly, reducing the possibility of the foaming material overflowing from the first mounting hole 102 into the compartment 101 during the foaming process after the shelf member 200 is installed in the metal liner 100. At the same time, an indirect connection between the shelf member 200 and the metal liner 100 is achieved through the direct connection between the first connecting member 310 and the second connecting member 320. Compared with the related art in which the metal liner 100 and the shelf member 200 are directly connected with screws, the damage to the surface of the metal liner 100 is reduced, and the second connecting member 320 and the metal liner 100 are isolated, thereby reducing the possibility of rust on the metal liner 100.

[0056] According to the storage device provided in the embodiment of the present application, the first connecting member 310 is riveted to the metal liner 100 through the first mounting hole 102, and the second connecting member 320 is used to connect the first connecting member 310 and the shelf member 200 through the third mounting hole 3101, so that the inner wall of the metal liner 100 and the shelf member 200 are tightly fitted, reducing the possibility of rust and overflow of the metal liner 100, and improving the product's qualification rate and service life.

[0057] In some embodiments, as Figure 8 As shown, the shelf member 200 is provided with a plurality of second mounting holes 201 spaced apart along the length of the shelf member 200 to improve the stability of the connection between the metal liner 100 and the shelf member 200 and enhance the support of the shelf. It should be noted that the number of second mounting holes 201 can be designed according to actual needs and is not specifically limited in this embodiment.

[0058] It can be understood that the sum of the number of the second mounting holes 201 of all shelf members 200 , the number of the connecting structures 300 , and the number of the first mounting holes 102 are equal.

[0059] It should be noted that a plurality includes two and more than two.

[0060] In some embodiments, as Figure 6 and Figure 7As shown, the first connecting member 310 includes a first section 311 and a second section 312. The first section 311 is partially disposed in the first mounting hole 102 and extends in a direction away from the shelf member 200. The second section 312 is connected to the first section 311, and the outer diameter of the second section 312 is larger than the outer diameter of the first section 311. The second section 312 abuts against the inner wall portion of the metal liner 100 located at the edge of the first mounting hole 102. The third mounting hole 3101 passes through the second section 312 and extends to the first section 311. The cross-section of the second section 312 includes, but is not limited to, a circle. It should be noted that the outer diameters of the first section 311 and the second section 312 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0061] It should be noted that the second section 312 is in contact with the side of the metal liner 100 close to the shelf 200 , a portion of the first section 311 is disposed in the first mounting hole 102 , and another portion of the first section 311 is located on the side of the metal liner 100 away from the shelf 200 .

[0062] It can be understood that since the first connecting member 310 and the metal liner 100 are riveted together, that is, the first section 311 is partially compressed and deformed until the part of the first section 311 close to the second section 312 is arranged in the first mounting hole 102, and the outer diameter of the second section 312 is larger than the outer diameter of the first section 311, so that the second section 312 can form a closer contact with the side of the metal liner 100 close to the shelf member 200, reducing the possibility of overflow due to the gap between the metal liner 100 and the shelf member 200, and helping to form a good seal between the second section 312 and the inner wall of the metal liner 100, reducing the possibility of cold air leakage and rusting of the metal liner 100, and improving the energy efficiency of the storage device.

[0063] In addition, the third mounting hole 3101 passes through the second section 312 and extends to the first section 311 , thereby increasing the contact area between the second connecting member 320 and the first connecting member 310 and improving the overall stability and reliability of the connection structure 300 .

[0064] In some embodiments, the first connecting member 310 is an integrally formed structure to improve the strength of the entire first connecting member 310 .

[0065] In some embodiments, as Figure 3 、 Figure 6 and Figure 7As shown, the first section 311 includes a first sub-segment 3111 and a second sub-segment 3112. One end surface of the first sub-segment 3111 is connected to the second section 312, and a portion of the outer wall of the first sub-segment 3111 abuts the inner edge of the first mounting hole 102. The second sub-segment 3112 is disposed at the other end of the first sub-segment 3111. The outer diameter of the first sub-segment 3111 is larger than the outer diameter of the second sub-segment 3112. The third mounting hole 3101 passes through the first sub-segment 3111 and extends to the second sub-segment 3112. The cross-section of the second sub-segment 3112 includes, but is not limited to, a circular shape. It should be noted that the outer diameters of the first sub-segment 3111 and the second sub-segment 3112 can be designed according to actual needs and are not specifically limited in this embodiment.

[0066] It is understood that the second section 312, the first sub-section 3111, and the second sub-section 3112 are sequentially connected, and the first sub-section 3111 is partially compressed and deformed until the portion of the first sub-section 3111 adjacent to the second section 312 is positioned within the first mounting hole 102. This facilitates the positioning of the first connector 310 within the first mounting hole 102, thereby improving the structural stability of the entire storage device. The deformed portion of the first sub-section 3111 located outside the first mounting hole 102 abuts against the outer wall of the metal liner 100 at the edge of the first mounting hole 102, allowing the second sub-section 3112 to form a closer contact with the side of the metal liner 100 facing away from the shelf 200. This reduces the possibility of material overflow due to the gap between the metal liner 100 and the first connector 310, helps form a good seal between the first connector 310 and the outer wall of the metal liner 100, reduces the possibility of cold air leakage and rust on the metal liner 100, and improves the energy efficiency of the storage device.

[0067] At the same time, the third mounting hole 3101 passes through the second section 312 and the first subsection 3111 and extends to the second subsection 3112, thereby increasing the contact area between the second connecting member 320 and the first connecting member 310 and improving the overall stability and reliability of the connection structure 300.

[0068] In addition, since the outer diameter of the first sub-segment 3111 of the first section 311 is larger than the outer diameter of the second sub-segment 3112, that is, the outer diameters of the second section 312, the first sub-segment 3111 and the second sub-segment 3112 gradually become smaller, it helps to disperse the load, reduce local stress concentration, optimize the riveted connection, and enhance the firmness of the connection between the metal liner 100, the shelf member 200 and the connecting structure 300.

[0069] In some embodiments, as Figure 3 、 Figure 6 and Figure 7 As shown, at least one of the cross section of the first sub-segment 3111 and the cross section of the first mounting hole 102 is an N-gon, where N=2n, and n is a natural number greater than or equal to 1.

[0070] It is understood that the first subsegment 3111 of the N-gon cross-section provides more contact points with the inner wall of the first mounting hole 102. This not only evenly distributes the load, reduces stress concentration, and improves the durability and reliability of the connection structure 300, but also serves as anti-rotation support points, reducing the possibility of the first connecting member 310 rotating relative to the first mounting hole 102 during the installation of the second connecting member 320 in the third mounting hole 3101, thereby increasing the stability of the connection structure 300. Furthermore, because the N-gon has an even number of sides, it also facilitates positioning and guiding during automated loading, improving loading stability, flexibility, and efficiency.

[0071] Similarly, the inner wall of the first mounting hole 102 with an N-gonal cross-section provides more contact points with the outer wall of the first sub-segment 3111, which can not only evenly distribute the load, reduce stress concentration, and improve the durability and reliability of the connection structure 300, but also use these contact points as anti-rotation support points, thereby reducing the possibility of the first connecting member 310 driving the rotation relative to the first mounting hole 102 during the installation of the second connecting member 320 in the third mounting hole 3101, thereby increasing the stability of the connection structure 300.

[0072] In this embodiment, Figure 3 、 Figure 6 and Figure 7 As shown, the cross section of the first sub-segment 3111 and the cross section of the first mounting hole 102 are both square, that is, n=2.

[0073] In some other embodiments, at least one of the cross section of the first sub-segment 3111 and the cross section of the first mounting hole 102 is in an oval shape.

[0074] It can be understood that the first sub-segment 3111 of the oval-shaped cross-section provides more contact area with the inner wall portion of the first mounting hole 102, which can not only evenly distribute the load, reduce stress concentration, increase the torsional resistance of the first connecting member 310, and improve the durability and reliability of the connecting structure 300, but also reduce the possibility of the second connecting member 320 driving the first connecting member 310 to rotate relative to the first mounting hole 102 during the installation of the second connecting member 320 in the third mounting hole 3101 based on the oval-shaped shape, thereby increasing the stability of the connecting structure 300.

[0075] Similarly, the inner wall of the first mounting hole 102 with an N-gonal cross-section provides more contact points with the outer wall of the first sub-segment 3111, which can not only evenly distribute the load, reduce stress concentration, increase the torsional resistance of the first connecting member 310, and improve the durability and reliability of the connecting structure 300, but also use these contact points as anti-rotation support points, thereby reducing the possibility of the first connecting member 310 being driven to rotate relative to the first mounting hole 102 during the installation of the second connecting member 320 in the third mounting hole 3101, thereby increasing the stability of the connecting structure 300.

[0076] In some embodiments, as Figure 3 、 Figure 6 and Figure 7 As shown, the length of the first sub-segment 3111 along the extension direction of the first segment 311 is in the range of 1 to 3 mm, so as to ensure that the contact area between the first connecting member 310 and the metal liner 100 is as large as possible.

[0077] In this embodiment, the length of the first sub-segment 3111 along the extension direction of the first segment 311 is 2 mm.

[0078] In some embodiments, as Figures 4 to 7 As shown, the outer side wall of the second section 312 and the two end surfaces of the second section 312 are both provided with rounded corners.

[0079] It can be understood that a chamfer is provided between the outer wall of the second section 312 and the end face of the second section 312 close to the shelf member 200, and a chamfer is provided between the outer wall of the second section 312 and the end face of the second section 312 close to the metal liner 100, so as to reduce the possibility of the first connecting member 310 damaging the surface coating of the metal liner 100 during pressing, reduce the possibility of the metal liner 100 rusting, and improve the production quality of the metal liner 100.

[0080] Exemplarily, the radius of the rounded corner is 0.1 mm.

[0081] In some embodiments, as Figure 5 and Figure 6 As shown, the third mounting hole 3101 is a blind hole.

[0082] It can be understood that the third mounting hole 3101 only passes through the second section 312 and the first sub-section 3111, thereby reducing the gap formed at the third mounting hole 3101 when installing the second connecting member 320, thereby reducing the risk of foam material overflowing from the third mounting hole 3101, and improving the sealing performance between the shelf member 200 and the metal inner liner 100, reducing the leakage of cold air, and improving the energy efficiency of the storage device.

[0083] In some embodiments, as Figure 5 and Figure 6As shown, the diameter of the third mounting hole 3101 gradually increases in a direction approaching the shelf member 200 .

[0084] It can be understood that the aperture of the third mounting hole 3101 near the second sub-section 3112 is smaller than the aperture of the third mounting hole 3101 near the second section 312, thereby facilitating the die-casting of the first connecting member 310 and reducing the friction and resistance during the installation of the second connecting member 320, and improving the tightness and stability of the connection between the shelf member 200 and the metal inner liner 100.

[0085] Exemplarily, the taper of the third mounting hole 3101 is 1°.

[0086] In this embodiment, Figure 5 and Figure 6 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.

[0087] In some embodiments, as Figure 2 、 Figure 4 and Figure 5 As shown, the second connecting member 320 is a self-tapping screw.

[0088] It is understood that, compared to ordinary screws, self-tapping screws can directly form their own threads on the first connecting member 310 during installation, eliminating the need for pre-tapping the first connecting member 310. This can speed up the manufacturing and installation process and improve efficiency. It can also reduce the need for additional fasteners such as nuts and washers, simplifying the entire connection structure 300 and reducing assembly complexity.

[0089] In some embodiments, as Figures 4 to 6 As shown, the inner sidewall of the metal liner 100 is recessed outward to form a groove 103. The groove 103 corresponds one-to-one with the first mounting hole 102. The first mounting hole 102 is located at the bottom of the groove 103. The shelf member 200 abuts against the inner wall of the metal liner 100 at the edge of the groove 103. It should be noted that the size and shape of the groove 103 can be designed according to actual needs and are not specifically limited in this embodiment.

[0090] It can be understood that by making the side wall portion of the metal liner 100 concave in the direction away from the shelf member 200, the structural strength of the metal liner 100 is enhanced, and the shelf member 200 and the metal liner 100 are fitted on the surface while avoiding the first connecting member 310, thereby improving the air insulation effect and reducing the possibility of rust on the metal liner 100. At the same time, the tightly fitted metal liner 100 and the shelf member 200 can also reduce the possibility of overflow during foaming, thereby improving the quality of the storage device.

[0091] In some embodiments, as Figure 1As shown, the metal liner 100 is assembled from multiple sheet metal parts. 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 sheet metal parts can be designed based on actual needs and are not specifically limited in this embodiment.

[0092] It is understood that sheet metal parts can be produced through standardized processing techniques such as cutting, stamping, and bending, making the manufacturing process of the metal liner 100 more efficient and controllable. At the same time, the splicing design makes the assembly process more flexible and facilitates large-scale production. Compared to a one-piece metal liner 100, the metal liner 100 formed by splicing multiple sheet metal parts has lower manufacturing and maintenance costs, is easier to transport and store, and has greater flexibility.

[0093] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more.
