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

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a storage device in which a first connecting member is sealedly connected to a metal inner container via a flange portion protruding from the edge of a first mounting hole, and a second connecting member is used to connect the first connecting member to a shelf member through a third mounting hole, thereby achieving a tight fit between the inner side wall of the metal inner container and the shelf member, reducing the possibility of rust and overflow of the metal inner container, and improving the product's qualification rate and service life.

[0004] In a first aspect, the present application provides a storage device, comprising:

[0005] A metal liner, forming a compartment and a plurality of first mounting holes;

[0006] at least two shelf members, the shelf members being located within the compartment and forming a second mounting hole;

[0007] a plurality of flanges provided on the metal liner and corresponding one to one with the first mounting holes, the flanges extending from the edge of the first mounting hole toward the metal liner in a direction away from the shelf member to the outside of the metal liner;

At the same time, the direct connection between the first connecting member and the second connecting member achieves an indirect connection between the shelf member and the metal liner. Compared with the related art method of directly connecting the metal liner and the shelf member with screws, this reduces damage to the surface of the metal liner, serves to isolate the second connecting member from the metal liner, and reduces the possibility of rusting of the metal liner.

[0014] The first section. One end of the first section is disposed at the bottom of the receiving groove, and the flange portion is located between the outer side wall of the first section and the inner side wall of the receiving groove;

[0015] The second section, one end of the second section is arranged at the other end of the first section, the other end of the second section passes through the first mounting hole and extends into the compartment, and the third mounting hole passes through the second section and the first section and extends to the main body.

[0016] According to one embodiment of the present application, at least one of the cross section of the first section and the cross section of the flange portion is an N-gon, and N=2n, where n is a natural number greater than or equal to 1; or

[0017] At least one of a cross section of the first section and a cross section of the flange portion has an oval shape.

[0018] According to one embodiment of the present application, at least one weight-reducing hole is formed in the main body.

[0019] According to one embodiment of the present application, the connection structure further includes:

[0020] A sealing member is located in the receiving groove, and an outer wall of the sealing member is respectively in contact with the outer wall of the protrusion, the inner wall of the receiving groove, and a side of the flange away from the first mounting hole.

[0021] According to one embodiment of the present application, the connection structure further includes:

[0022] The third connecting member is arranged at the outer edge of the slot of the accommodating slot and is respectively connected to the sides of the main body and the metal liner that are close to each other.

[0023] According to one embodiment of the present application, the diameter of the third mounting hole gradually increases in a direction approaching the shelf member; and / or

[0024] The third mounting hole is a blind hole.

[0025] According to one embodiment of the present application, the second connecting member is a self-tapping screw.

[0050] 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.

[0051] Reference below Figures 1-8 The storage device provided by an embodiment of the present application is described, and the storage device includes a metal inner container 100 , at least two shelf members 200 , a plurality of flange portions 400 and a plurality of connection structures 300 .

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] In this embodiment, the shelf member 200 extends in the up-down direction, and the object storage member extends in the left-right direction.

[0058] The flange portion 400 is disposed on the metal inner liner 100 and corresponds one-to-one with the first mounting hole 102. The flange portion 400 extends from the edge of the first mounting hole 102 toward the metal inner liner 100, away from the shelf member 200, and extends to the outside of the metal inner liner 100. It should be noted that the shape and size of the flange portion 400 can be designed according to actual needs and are not specifically limited in this embodiment.

[0059] It is understood that the flange portion 400 protrudes from the side of the metal liner 100 away from the shelf member 200 to increase the contact area with the connecting structure 300, improving the stability and durability of the storage device. Furthermore, during the foaming process, the flange portion 400 is squeezed by the foaming material, ensuring a tighter fit between the connecting structure 300 and the metal liner 100. Furthermore, because the flange portion 400 is positioned at the edge of the first mounting hole 102, it insulates and protects the first mounting hole 102, thereby reducing the risk of rust and overflow.

[0060] The connection structure 300 corresponds to the first mounting hole 102 one by one. The connection structure 300 includes a first connecting member 310 and a second connecting member (not shown). The first connecting member 310 is sealed with the flange portion 400, and the first connecting member 310 partially extends through the first mounting hole 102 into the compartment 101. The first connecting member 310 forms a third mounting hole 3101. One end of the second connecting member passes through the second mounting hole 201 and cooperates with the third mounting hole 3101.

[0061] It should be noted that the material of the first connecting member 310 includes, but is not limited to, ABS (Acrylonitrile Butadiene Styrene) or PP (Polypropylene). The material of the second connecting member includes, but is not limited to, aluminum alloy or zinc alloy. The connection between the first connecting member 310 and the second connecting member 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 are not specifically limited in this embodiment.

[0062] 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 is positioned using the first mounting hole 102 and is sealed with the metal liner 100 through the flange portion 400, which can make the connection between the metal liner 100 and the first connecting member 310 tighter and reduce the generation of gaps. It not only reduces the possibility of the foaming material overflowing from the first mounting hole 102 into the compartment 101, but also reduces 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 connects 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 on 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. 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, the second connecting member and the metal liner 100 are isolated, and the possibility of rusting of the metal liner 100 is reduced.

[0063] According to the storage device provided in the embodiment of the present application, the first connecting member 310 is sealedly connected to the metal liner 100 through the flange portion 400 protruding from the edge of the first mounting hole 102, and the second connecting member 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.

[0064] In some embodiments, 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 ranges from 1 to 3 mm to ensure that the contact area between the first connecting member 310 and the flange portion 400 is as large as possible.

[0065] In this embodiment, the length of the flange portion 400 along the axis of the first mounting hole 102 is 2 mm.

[0066] In some embodiments, as Figure 2 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.

[0067] 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.

[0068] It should be noted that a plurality includes two and more than two.

[0069] In some embodiments, as Figures 3 to 6 and Figure 8 As shown, the first connector 310 includes a main body 311 and a raised portion 312. The main body 311 is disposed outside the metal liner 100 and forms a receiving groove 3111. The flange 400 is at least partially located within the receiving groove 3111 and is sealed therewith. One end of the raised portion 312 is disposed at the bottom of the receiving groove 3111, and the other end of the raised portion 312 extends through the first mounting hole 102 into the compartment 101. The third mounting hole 3101 passes through the raised portion 312 and extends to the main body 311. It should be noted that the shapes and sizes of the main body 311, raised portion 312, and receiving groove 3111 can be designed according to actual needs and are not specifically limited in this embodiment.

[0070] It should be noted that the main body 311 is located on the side of the metal liner 100 away from the shelf 200, and the protrusion 312 partially passes through the first mounting hole 102 and extends into the compartment 101, so that the shelf 200 can be connected to the protrusion 312 through the second connecting member.

[0071] As will be appreciated, on the one hand, the receiving groove 3111 formed in the main body 311 of the first connector 310 is sealedly connected to the flange 400, improving the sealing performance of the storage device while making the entire storage device more compact. Furthermore, during the foaming process, the foaming material can be used to squeeze the flange 400, ensuring a tighter fit between the first connector 310 and the flange 400. On the other hand, the flange 400 is at least partially located within the receiving groove 3111, providing some protection for the flange 400. This ensures that the foaming material passes through the receiving groove 3111 before flowing into the first mounting hole 102, extending the flow path of the foaming material and reducing the possibility of overflow. The solidification of the foaming material further strengthens the connection between the main body 311 and the flange 400, helping to form a good seal between the outer wall of the flange 400 and the inner wall of the receiving groove 3111, reducing the possibility of cold air leakage and rusting of the metal liner 100, thereby improving the energy efficiency of the storage device.

[0072] At the same time, one end of the protrusion 312 is arranged at the bottom of the accommodating groove 3111, and the other end passes through the first mounting hole 102 and extends into the compartment 101, thereby increasing the contact area between the protrusion 312 and the main body 311, improving the connection strength and making the structure of the first connecting member 310 more compact.

[0073] In addition, the third mounting hole 3101 passes through the raised portion 312 and extends to the main body 311 , thereby increasing the contact area between the second connecting member and the first connecting member 310 and improving the overall stability and reliability of the connection structure 300 .

[0074] In some embodiments, as Figure 5 and 8 As shown, the main body 311 forms at least one weight-reducing hole 3112. It should be noted that the number, shape and size of the weight-reducing holes 3112 can be designed according to actual needs, and are not specifically limited in this embodiment.

[0075] It can be understood that by providing the weight-reducing holes 3112 , not only the possibility of injection deformation of the first connecting member 310 can be reduced, but also the manufacturing cost can be saved.

[0076] In this embodiment, Figure 5 and 8 As shown, a plurality of weight-reducing holes 3112 are provided, and the plurality of weight-reducing holes 3112 are arranged around the outside of the accommodating groove 3111 .

[0077] Exemplarily, six lightening holes 3112 are provided.

[0078] In some embodiments, as Figure 5 As shown, the weight-reducing hole 3112 is a blind hole, which reduces the possibility of the foaming material flowing from the weight-reducing hole 3112 into the receiving groove 3111, reduces the risk of overflow, and improves the sealing performance between the first connecting member 310 and the metal inner liner 100, reduces the leakage of cold air, and improves the energy efficiency of the storage device.

[0079] In some embodiments, as Figure 3 、 Figure 5 、 Figure 6 and Figure 8 As shown, the raised portion 312 includes a first section 3121 and a second section 3122. One end of the first section 3121 is disposed at the bottom of the receiving groove 3111, and the flange portion 400 is located between the outer wall of the first section 3121 and the inner wall of the receiving groove 3111. One end of the second section 3122 is disposed at the other end of the first section 3121, and the other end of the second section 3122 extends through the first mounting hole 102 into the compartment 101. The third mounting hole 3101 passes through the second section 3122 and the first section 3121 and extends to the main body 311. The shape of the second section 3122 includes, but is not limited to, a circle. It should be noted that the length and shape of the first section 3121 and the second section 3122 can be designed according to actual needs and are not specifically limited in this embodiment.

[0080] It is understood that the segmented design of the raised portion 312 can disperse stress and reduce stress concentration, thereby improving the durability and reliability of the connection point. The lengths of the first segment 3121 and the second segment 3122 can be adjusted as needed to accommodate different installation requirements. Furthermore, the first segment 3121 and the inner sidewall of the receiving groove 3111 position the flange portion 400, allowing the foaming material to squeeze the flange portion 400 during the foaming process, resulting in a tighter fit between the first segment 3121 and the flange portion 400. Furthermore, the second segment 3122 positions the first mounting hole 102, thereby ensuring that the first connector 310 is connected to the flange portion 400 and the metal liner 100, while also enhancing the strength of the first connector 310.

[0081] In addition, the third mounting hole 3101 sequentially passes through the second section 3122 and the first section 3121 and then extends to the main body 311 , thereby increasing the contact area between the second connector and the first connector 310 and improving the overall stability and reliability of the connection structure 300 .

[0082] In some embodiments, as Figure 3 、 Figure 5 、 Figure 6 and Figure 8 As shown, the outer diameter of the second section 3122 is smaller than the outer diameter of the first section 3121, which helps to reduce stress concentration, improve the structural fatigue life of the first connecting member 310, and facilitates the second section 3122 to pass through the first mounting hole 102, reducing the resistance during the installation process and the wear on the edge of the first mounting hole 102, improving assembly efficiency, helping to reduce the structural weight, and achieving a weight-saving design.

[0083] In some embodiments, as Figure 8 As shown, the main body portion 311 and the protruding portion 312 are an integrally formed structure to improve the strength of the entire first connecting member 310 .

[0084] In some embodiments, as Figure 3 and Figure 8 As shown, at least one of the cross section of the first section 3121 and the cross section of the flange portion 400 is an N-gon, where N=2n, and n is a natural number greater than or equal to 1.

[0085] It is understood that the first section 3121 of the N-gon cross-section provides more contact points with the inner wall of the flange portion 400. This not only evenly distributes the load, reduces stress concentration, and improves the durability and reliability of the first connector 310, but also serves as anti-rotation support, reducing the possibility of the first connector 310 rotating relative to the first mounting hole 102 during installation of the second connector 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.

[0086] Similarly, the flange portion 400 with an N-gonal cross-section provides more contact points with the outer wall portion of the first section 3121, which not only evenly distributes the load, reduces stress concentration, and improves the durability and reliability of the first connecting member 310, but also serves 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 in the third mounting hole 3101, thereby increasing the stability of the connecting structure 300.

[0087] In this embodiment, Figure 3 and Figure 8 As shown, the cross-sections of the first section 3121 and the flange portion 400 are both square, ie, n = 2. Similarly, since the flange portion 400 is disposed at the edge of the first mounting hole 102 , the first mounting hole 102 is also square.

[0088] In some other embodiments, at least one of the cross-section of the first section 3121 and the cross-section of the flange portion 400 is in a rounded shape.

[0089] It can be understood that the first section 3121 of the oval-shaped cross-section provides more contact area with the inner wall portion of the flange portion 400, 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.

[0090] Similarly, the flange portion 400 with an oval cross-section provides more contact points with the inner wall portion of the first section 3121, 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 first connecting member 310, 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 in the third mounting hole 3101, thereby increasing the stability of the connecting structure 300.

[0091] In some embodiments, as Figure 3 、 Figure 5 and Figure 6 As shown, the connection structure 300 further includes a sealing member 330. The sealing member 330 is located within the receiving groove 3111, and the outer wall of the sealing member 330 abuts against the outer wall of the protrusion 312, the inner wall of the receiving groove 3111, and the surface of the flange portion 400 away from the first mounting hole 102. The sealing member 330 includes, but is not limited to, a sealing ring.

[0092] It should be noted that a closed sealing surface is formed between the outer wall of the seal 330, the outer wall of the flange portion 400 and the inner wall of the accommodating groove 3111 to reduce the foaming material from flowing into the first mounting hole 102 from between the inner wall of the flange portion 400 and the outer wall of the first section 3121.

[0093] It can be understood that by providing the seal 330, an effective seal is formed between the first connecting member 310 and the flange portion 400 to prevent leakage of cold air and intrusion of foaming material, and the elastic properties of the seal 330 are utilized to adapt to thermal expansion and contraction caused by temperature changes, maintain sealing performance, reduce wear and corrosion, and thus improve the durability and service life of the entire storage device.

[0094] In some embodiments, as Figure 6 and Figure 8 As shown, considering the shapes of the flange portion 400 and the protrusion 312, the receiving groove 3111 is annular to ensure that the inner side walls of the receiving groove 3111 correspond one-to-one with the inner side walls of the flange portion 400 and the outer side of the protrusion 312.

[0095] In some embodiments, considering that the length of the flange portion 400 along the axis of the first mounting hole 102 ranges from 1 to 3 mm, the width of the accommodating groove 3111 ranges from 1 to 1.5 mm, and the depth of the accommodating groove 3111 ranges from 1 to 3 mm.

[0096] In this embodiment, the length of the flange portion 400 along the axis of the first mounting hole 102 is 2 mm, the width of the receiving groove 3111 is 1.23 mm, the depth of the receiving groove 3111 is 2 mm, and the diameter of the sealing member 330 is 1.1 mm.

[0097] In some embodiments, as Figures 4 to 6 As shown, the connection structure 300 further includes a third connection member 340 , which is disposed at the outer edge of the slot of the receiving slot 3111 and is respectively connected to the sides of the main body 311 and the metal liner 100 that are close to each other.

[0098] It can be understood that the third connecting member 340 is located outside the notch of the accommodating groove 3111 to avoid the protrusion 312, and one side of the third connecting member 340 is arranged on the side of the main body 311 close to the metal inner liner 100, and the other side of the third connecting member 340 is connected to the side of the metal inner liner 100 close to the main body 311, thereby increasing the contact area between the first connecting member 310 and the metal inner liner 100, so that the flange portion 400 is hidden, thereby improving the sealing performance and reducing the possibility of overflow.

[0099] In this embodiment, the third connecting member 340 includes a double-sided sponge tape, that is, the third connecting member 340 is respectively adhered to the main body 311 and the metal liner 100 to provide a simplified installation process while providing a stable connection, and filling the uneven parts on the surface of the metal liner 100 and the main body 311, which helps to form a better seal, absorb vibration and reduce noise, thereby improving the comfort of use of the storage device and reducing manufacturing costs and maintenance costs.

[0100] In some embodiments, as Figure 5 As shown, the third mounting hole 3101 is a blind hole.

[0101] It can be understood that the third mounting hole 3101 only passes through the second section 3122 and the first section 3121, thereby reducing the gap formed at the third mounting hole 3101 when installing the second connecting member, 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.

[0102] In some embodiments, as Figure 5 As shown, the diameter of the third mounting hole 3101 gradually increases in a direction approaching the shelf member 200 .

[0103] It can be understood that the diameter of the third mounting hole 3101 close to the second section 3122 is smaller than the diameter of the third mounting hole 3101 close to the main body 311, 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, and improving the tightness and stability of the connection between the shelf member 200 and the metal inner liner 100.

[0104] Exemplarily, the taper of the third mounting hole 3101 is 1°.

[0105] In this embodiment, Figure 5 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.

[0106] In some embodiments, the second connecting member is a self-tapping screw.

[0107] 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.

[0108] In some embodiments, as Figure 1 As 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.

[0109] 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.
