[0035] The embodiments of this utility model 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 utility model, and should not be construed as limiting this utility model.

[0036] Currently, all refrigeration equipment enclosures require insulation. During the manufacturing process, foaming liquid needs to be injected into the foaming cavity of the enclosure to form a heat-insulating foam layer. During the foaming process, the foaming liquid will generate high-temperature gas. If the high-temperature gas remains in the enclosure and cannot be discharged smoothly, the concentrated thermal stress can easily cause the enclosure structure to crack.

[0037] In related technologies, high-temperature gas is discharged by arranging vent holes on the base plate assembly. However, the foaming liquid is prone to leaking out of the vent holes to the outside of the box, resulting in foam leakage. Some of the foaming liquid is located on the outer wall of the box, affecting the appearance of the box.

[0038] Based on this, refer to Figure 1 As shown, a bottom plate assembly 1000 is provided in an embodiment of this utility model. The bottom plate assembly 1000 is applied in a box and is located at the bottom of the box. The bottom plate assembly 1000 includes a bottom plate body 100, and the bottom plate body 100 is provided with an exhaust channel 111. The exhaust channel 111 penetrates the upper and lower sides of the bottom plate body 100, so that the upper end of the exhaust channel 111 communicates with the foaming cavity of the box. (Refer to...) Figure 4 As shown, the inner wall of the exhaust channel 111 is also provided with a boss 112. The boss 112 can be understood as a protruding structure or a baffle structure. The boss 112 can prevent the foaming liquid from flowing or expanding along the exhaust channel 111. Furthermore, the boss 112 does not completely close the exhaust channel 111. In other words, the boss 112 is constructed to narrow or reduce the flow cross-section of the exhaust channel 111 at a local location. The boss 112 will reduce the flow cross-section of the exhaust channel 111 at the position of the boss 112 relative to the flow cross-section at other positions. When the foaming liquid passes through the position of the boss 112, the flow rate of the foaming liquid will decrease due to the reduced flow cross-section, thereby preventing the foaming liquid from passing through the boss 112.

[0039] During the manufacturing process of the enclosure, when foaming liquid is injected into the foaming cavity of the enclosure, initially, the foaming liquid generally flows from top to bottom. At this time, the foaming liquid has not yet reached the exhaust channel 111. The high-temperature gas generated by the foaming liquid can be discharged to the outside of the enclosure through the exhaust channel 111. The high-temperature gas is not easy to remain in the foaming cavity of the enclosure, which can reduce the impact of thermal stress and protect the structure of the enclosure. Then, when the foaming liquid reaches the exhaust channel 111, the foaming liquid will flow from top to bottom and enter the exhaust channel 111. The boss 112 can prevent the foaming liquid from passing through the exhaust channel 111. Since the foaming liquid will adhere to the inner wall of the exhaust channel 111, it can slow down the flow rate of the foaming liquid, making it less likely for the foaming liquid to leak to the outside of the exhaust channel 111, which can reduce the occurrence of foam leakage. Finally, after a period of time, the foaming liquid will gradually expand, thereby filling the exhaust channel 111 and sealing the exhaust channel 111.

[0040] It should be noted that when the foaming liquid cools in the foaming cavity of the box, it will form a foam layer. The foam layer can be a foam material, which plays a role in heat preservation.

[0041] Reference Figure 4 and Figure 5 As shown, according to other embodiments of the present invention, the boss 112 extends circumferentially along the exhaust channel 111, which can also be understood as the boss 112 extending around the center line of the exhaust channel 111. The boss 112 extends into a disc structure, and the boss 112 and the exhaust channel 111 are an integral structure. The outer peripheral wall of the boss 112 is connected to the inner wall of the exhaust channel 111. The exhaust channel 111 can be understood as a stepped hole structure. Specifically, the exhaust channel 111 extends in the vertical direction, and the exhaust channel 111 includes a first hole segment arranged sequentially from top to bottom. The first hole section 1111 and the second hole section 1112 can be understood as a through hole structure, and the first hole section 1111 and the second hole section 1112 are interconnected. The second hole section 1112 is formed on the boss 112 and penetrates the boss 112 in the vertical direction. Furthermore, the inner diameter of the second hole section 1112 is smaller than the inner diameter of the first hole section 1111. The second hole section 1112 is mainly used to narrow the flow cross section of the exhaust channel 111. The inner diameter of the second hole section 1112 can be set to 0.5mm-2mm.

[0042] In this embodiment, when the foaming liquid foams and forms in the foaming cavity of the housing, the high-temperature gas generated by the foaming liquid can be discharged to the outside of the housing through the first orifice 1111 and the second orifice 1112. When the foaming liquid enters the exhaust channel 111, a stepped hole is formed due to the different inner diameters of the first orifice 1111 and the second orifice 1112. As the foaming liquid flows along the exhaust channel 111, it first accumulates in the first orifice 1111. The first orifice 1111 can accumulate a certain volume of foaming liquid, and the foaming liquid adheres to the first orifice 1111. The inner wall of 111 makes it difficult for the foaming liquid to flow downwards. At this time, the high-temperature gas generated by the foaming liquid can be discharged to the outside of the exhaust channel 111 through the second hole section 1112. In addition, since the inner diameter of the second hole section 1112 is relatively small, the flow cross section of the exhaust channel 111 is relatively narrowed. When the foaming liquid flows from the first hole section 1111 to the second hole section 1112, the flow rate is reduced, making it difficult for the foaming liquid to pass through the second hole section 1112 and to leak out to the outside of the exhaust channel 111.

[0043] In some other embodiments, the boss 112 may be constructed in other shapes, such as a fan-shaped structure, with a gap formed between the outer wall of the boss 112 and the inner wall of the exhaust channel 111, through which the high-temperature gas generated by the foaming liquid can leave the exhaust channel 111 and be discharged to the outside of the housing.

[0044] Reference Figure 4 and Figure 5 As shown, in some embodiments, since the first orifice 1111 is mainly used for accumulating foaming liquid and the second orifice 1112 is mainly used for venting the high-temperature gas generated by the foaming liquid, the length of the first orifice 1111 is greater than the length of the second orifice 1112 in the vertical direction. This arrangement can increase the area of ​​the inner wall of the first orifice 1111, so that more foaming liquid can adhere to the inner wall of the first orifice 1111. The first orifice 1111 can accumulate more foaming liquid, which helps to hinder the downward flow of the foaming liquid, thereby slowing down the speed at which the foaming liquid flows out of the first orifice 1111. The high-temperature gas generated by the foaming liquid can be discharged to the outside of the exhaust channel 111 through the second orifice 1112.

[0045] Reference Figure 5 As shown, in some embodiments, the boss 112 can be located at the lower end of the exhaust channel 111, which can increase the volume of the first hole section 1111 and the inner wall area of ​​the first hole section 1111. The first hole section 1111 can accommodate more foaming liquid, making it less likely for the foaming liquid to flow out of the exhaust channel 111 to the outside.

[0046] Reference Figure 4As shown, according to some embodiments of the present invention, the exhaust channel 111 further includes a third hole segment 1113, which is located below the second hole segment 1112. Specifically, the first hole segment 1111, the second hole segment 1112, and the third hole segment 1113 are arranged sequentially from top to bottom and are connected sequentially from top to bottom. When the foaming liquid enters the exhaust channel 111, the foaming liquid will pass through the first hole segment 1111, the second hole segment 1112, and the third hole segment 1113 in the arrangement order. Furthermore, the inner diameter of the third hole segment 1113 is larger than the inner diameter of the second hole segment 1112, and the inner diameter of the third hole segment 1113 can be approximately equal to the inner diameter of the first hole segment 1111. At the same time, along the vertical direction, the length of the third hole segment 1113 is greater than the length of the first hole segment 1111. It should be noted that, since the foaming liquid will accumulate in the first hole section 1111, if the length of the first hole section 1111 is too large, the accumulation height of the foaming liquid in the first hole section 1111 may be too high, and the foaming liquid in the first hole section 1111 may easily block the first hole section 1111, making it difficult for the high-temperature gas generated by the foaming liquid to pass through the first hole section 1111. Therefore, the length of the first hole section 1111 can be set to be less than the length of the third hole section 1113. The length of the first hole section 1111 is relatively suitable, so that the height of the foaming liquid accumulated in the first hole section 1111 is more suitable. The high-temperature gas can pass through the first hole section 1111 more easily, and then pass through the second hole section 1112 and the third hole section 1113 in sequence to be discharged to the outside of the exhaust channel 111. At the same time, it is also ensured that the exhaust channel 111 has a certain height. The exhaust channel 111 has a certain height, which makes it difficult for the foaming liquid on the base plate body 100 to enter the exhaust channel 111, thus playing a blocking effect.

[0047] Reference Figure 4 As shown, in some embodiments, the boss 112 can guide part of the foaming liquid in the second hole section 1112 to flow along the bottom wall of the boss 112, thereby guiding part of the foaming liquid to the inner wall of the third hole section 1113. Part of the foaming liquid is not easy to drip directly vertically down from the second hole section 1112, but can flow along the bottom wall of the boss 112 to the inner wall of the third hole section 1113. Since the foaming liquid adheres to the inner wall of the third hole section 1113, the flow speed of the foaming liquid can be slowed down, making it less likely for the foaming liquid to leak out of the exhaust channel 111.

[0048] Reference Figure 2 and Figure 4As shown, according to some embodiments of the present invention, the base plate body 100 is provided with an upwardly protruding column portion 110, and an exhaust channel 111 is formed in the column portion 110. The column portion 110 structure can be machined on the base plate body 100 using an integral molding process, thereby simplifying the manufacturing process. In this embodiment, since the column portion 110 protrudes upwards, a certain height of foaming liquid needs to be accumulated above the base plate body 100 before the foaming liquid can enter the exhaust channel 111 from the top of the column portion 110. Furthermore, the column portion 110 does not occupy the space below the base plate body 100, which can reduce the space occupied by the base plate body 100. The upward extension of the column portion 110 can also increase the inner wall area of ​​the exhaust channel 111, allowing more foaming liquid to adhere to the inner wall of the exhaust channel 111. That is, the contact area between the foaming liquid and the inner wall of the exhaust channel 111 is increased, which can hinder the flow of foaming liquid along the exhaust channel 111. The foaming liquid is less likely to flow out of the exhaust channel 111, which helps to reduce the occurrence of foam leakage.

[0049] Reference Figure 4 As shown, according to some embodiments of the present invention, the column portion 110 is constructed as a cone shape. Specifically, the outer diameter of the column portion 110 gradually increases from top to bottom. It can be understood that the column portion 110 has a draft angle. When the base plate body 100 is manufactured using an integral molding process, the column portion 110 can be easily demolded, which facilitates manufacturing.

[0050] Reference Figure 4 As shown, in some embodiments, since the first hole segment 1111 and the third hole segment 1113 have a certain length, the inner diameter of the first hole segment 1111 and the inner diameter of the third hole segment 1113 can also gradually increase from top to bottom, thereby forming a draft angle. Such an arrangement can facilitate the demolding of the column part 110.

[0051] In related technologies, due to the relatively weak structural strength of the base plate assembly, in order to reduce cargo damage caused by impact, a large number of packaging protective structures (such as foam) are usually arranged to protect the base plate assembly. Currently, these packaging protection designs are heavy, with large packaging volume and high logistics costs.

[0052] Reference Figure 2 and Figure 6As shown, according to some embodiments of the present invention, at least a portion of the structure of the top wall of the base plate body 100 protrudes upward to form a protrusion 120. The protrusion 120 can be understood as a rectangular rib or boss structure. The protrusion 120 can be arranged at the front position of the base plate body 100. For example, in the front-rear direction, the maximum distance between the protrusion 120 and the front end of the base plate body 100 is less than or equal to 1 / 3 of the total length of the base plate body 100 in the front-rear direction. It can also be understood that the protrusion 120 falls within the front 1 / 3 area of ​​the base plate body 100. This is the optimal arrangement position of the protrusion 120, which can better improve the bending strength and torsional strength of the base plate body 100. The protrusion 120 extends in the front-rear direction, the width of the protrusion 120 in the left-right direction is 15mm-25mm, and the height of the protrusion 120 in the up-down direction is 2mm-5mm. Multiple protrusions 120 can be arranged at intervals along the left-right direction, which increases structural strength and bending resistance, making the base plate body 100 less prone to bending under impact, improving impact resistance, thus eliminating the need for packaging protection structures, driving packaging miniaturization, increasing container loading capacity, and lowering freight costs. A column portion 110 is located at the top of the protrusions 120, and the column portion 110 and protrusions 120 are an integral structure manufactured using a one-piece molding process. Multiple column portions 110 can be arranged at intervals along the extension direction of the protrusions 120. This arrangement allows multiple exhaust channels 111 to more evenly cover various areas of the base plate body 100, facilitating the discharge of high-temperature gases generated by the foaming liquid in each area, thereby reducing the impact of thermal stress. Additionally, refer to... Figure 4 As shown, since the protrusion 120 protrudes upwards, a corresponding groove 121 is formed on the lower side of the base plate body 100. The position of the groove 121 corresponds to the position of the protrusion 120. Since the column part 110 is located on top of the protrusion 120, the groove 121 is connected to the exhaust channel 111. With this arrangement, even if some foaming liquid leaks out from the exhaust channel 111, it will adhere to the inner wall of the groove 121 and remain in the groove 121. It can be understood that the groove 121 can accommodate a portion of the foaming liquid, and the foaming liquid is not easy to leak out of the groove 121, thus having a weak impact on the appearance of the box.

[0053] In some embodiments, the protrusion 120 and the base plate body 100 are integral structures, and the structure of the protrusion 120 can be processed by an integral molding process, which can simplify the manufacturing process.

[0054] Reference Figure 1 and Figure 6As shown in some embodiments of this utility model, the top wall of the base plate body 100 is provided with multiple crisscrossing first reinforcing ribs 130. Each first reinforcing rib 130 is a long strip structure, protruding upwards. The first reinforcing ribs 130 can increase the structural strength or bending strength of the base plate body 100, making it less prone to bending and improving impact resistance. This eliminates the need for a protective packaging structure, promotes packaging miniaturization, increases container loading capacity, and lowers freight costs. The first reinforcing ribs 130 can be arranged in areas of weaker rigidity on the base plate body 100 according to actual needs; for example, they can be arranged on the front side of the base plate body 100.

[0055] In some embodiments, a portion of the first reinforcing rib 130 may be arranged corresponding to the position of the protrusion 120. For example, in the front-rear direction, the maximum distance between the first reinforcing rib 130 and the front end of the base plate body 100 is less than or equal to 1 / 3 of the total length of the base plate body 100 in the front-rear direction. This can also be understood as the first reinforcing rib 130 falling into the position of the front 1 / 3 region of the base plate body 100, which can better improve the structural strength or bending strength of the base plate body 100.

[0056] Reference Figure 1 and Figure 6 As shown, in some embodiments, multiple first reinforcing ribs 130 are arranged in a grid pattern along the front-back and left-right directions. Viewed from above, the position of the protrusion 120 partially overlaps with the position of the first reinforcing ribs 130. This can be understood as the protrusion 120 being located within the area containing the multiple first reinforcing ribs 130. The protrusion 120 and the first reinforcing ribs 130 can jointly increase the structural strength or bending strength of the base plate body 100. Some of the first reinforcing ribs 130 extending in the left-right direction cross over the protrusion 120, meaning that some of the first reinforcing ribs 130 are connected to the protrusion 120 as a single unit, which can further increase the structural strength or bending strength of the base plate body 100.

[0057] Reference Figure 7As shown, this embodiment of the utility model also provides a box 2000, which includes a shell 300, an inner liner 310, a foaming layer, and a bottom plate assembly 1000 as described in the above embodiment. The inner liner 310 is disposed inside the shell 300 and has a storage compartment 311. The bottom plate assembly 1000 is connected to the bottom of the shell 300. A foaming cavity 320 is defined between the shell 300, the inner liner 310, and the bottom plate assembly 1000. The foaming layer is located in the foaming cavity 320. Within 20, during the manufacturing process of the cabinet 2000, after assembling the shell 300, inner liner 310 and bottom plate assembly 1000, foaming liquid needs to be injected into the foaming cavity 320 to form a foam layer inside the foaming cavity 320. The foam layer can block the heat from the outside of the cabinet 2000 from being transferred to the storage compartment 311 of the inner liner 310. It can also be understood as being used to prevent the external environment from affecting the temperature of the storage compartment 311, thus playing a role in heat insulation.

[0058] This utility model embodiment also provides a refrigeration device, which includes the cabinet 2000 of the above embodiment. The refrigeration device can be a refrigerator, freezer, wine cabinet, or other equipment.

[0059] Reference Figure 1 and Figure 3 As shown, in some embodiments, when the base plate assembly 1000 has a compressor compartment 200, the base plate body 100 can be a generally horizontally arranged plate structure. The compressor compartment 200 is connected to the base plate body 100. The compressor compartment 200 includes a front side plate 210, a left side plate 220, a right side plate 230, and an upper side plate 240. The front side plate 210, left side plate 220, and right side plate 230 are connected to the base plate assembly 1000. The left side plate 220 and right side plate 230 extend vertically and are arranged opposite each other. The front side plate 210 is connected between the left side plate 220 and right side plate 230. The upper side plate 240 extends horizontally and is connected above the front side plate 210, left side plate 220, and right side plate 230. The overall structure formed by the front side plate 210, left side plate 220, right side plate 230, and upper side plate 240 protrudes upward, thereby forming the compressor compartment 200 for accommodating components such as compressors and condensers.

[0060] In some other embodiments, the housing may not have a compressor compartment 200, and the base plate assembly 1000 may be a generally horizontally arranged plate structure.

[0061] It should be noted that in related technologies, the base plate body 100, front side plate 210, left side plate 220, right side plate 230 and upper side plate 240 are generally connected together by fasteners or welding, resulting in a large number of parts and making assembly more complicated.

[0062] Based on this, according to some embodiments of the present invention, the base plate body 100 and the compressor compartment 200 are an integral structure. Specifically, the base plate body 100, the front side plate 210, the left side plate 220, the right side plate 230 and the upper side plate 240 are integral structures. The base plate body 100, the front side plate 210, the left side plate 220, the right side plate 230 and the upper side plate 240 can be processed simultaneously using integral injection molding or metal die casting. The wall thickness of the main structure of the base plate assembly 1000 can be 2mm. The number of parts is relatively simplified, which can improve production efficiency and achieve the effect of improving efficiency and reducing costs.

[0063] In some embodiments, refer to Figure 1 and Figure 6 As shown, the base plate assembly 1000 also includes a second reinforcing rib 140. The second reinforcing rib 140 is a rib structure and can extend in the front-to-back direction. The second reinforcing rib 140 can be arranged between the base plate body 100 and the left side plate 220, or it can be arranged between the base plate body 100 and the right side plate 230, thereby enhancing the structural strength or bending strength of the base plate body 100 on the left and right sides. The thickness of the second reinforcing rib 140 can be 2mm, and there can be multiple second reinforcing ribs 140 arranged in a crisscross pattern. Multiple first reinforcing ribs 130 can be arranged in a crisscross pattern.

[0064] In some embodiments, refer to Figure 1 and Figure 6 As shown, the base plate assembly 1000 also includes a first reinforcing block 150. The first reinforcing block 150 is located near the left side plate 220 or near the right side plate 230 of the base plate body. The reinforcing block is mainly used to strengthen the structural strength or bending strength at this location. The thickness of the first reinforcing block 150 can be about 10mm to make the base plate assembly 1000 less prone to bending. The first reinforcing block 150 is located on at least one side of the compressor compartment 200 along its length. Figure 1 The left and right directions within. It is understandable that the first reinforcing block 150 could be a metal part or a thicker plastic part.

[0065] In some embodiments, threaded holes can be provided on the first reinforcing block 150 for fastener threaded connection. These fasteners are used to fix the base plate assembly 1000 and the compressor base plate. Since the first reinforcing block 150 is a thickened structure, it can improve the connection stability between the base plate assembly 1000 and the compressor base plate. The first reinforcing block 150 can be understood as an added thickness at the connection point between the base plate assembly 1000 and the compressor base plate, thereby improving the connection stability. The first reinforcing block 150 can be integrally formed with the base plate body 100 through injection molding or die casting, thus facilitating manufacturing. It should be noted that in related technologies, vacuum forming is used to manufacture the base plate assembly. However, vacuum forming makes it difficult to directly form the structure of the first reinforcing block on the base plate body. Furthermore, this area is where the compressor mounting plate and the housing are bolted together. The vacuum-formed base plate assembly cannot be bolted at this location, requiring additional reinforcing iron. Therefore, the solution in this embodiment is better.

[0066] In some embodiments, refer to Figure 1 and Figure 6 As shown, the base plate assembly 1000 also includes a second reinforcing block 250, which is located on at least one side of the compressor compartment 200 along its length direction. The width of the second reinforcing block 250 in the width direction of the compressor compartment 200 gradually increases from top to bottom. Figure 1 In the front-to-back direction, the second reinforcing block 250 can be understood as a trapezoidal boss structure. Specifically, the second reinforcing block 250 is connected to the left side plate 220 or the right side plate 230, which can increase the structural strength or bending strength of the left side plate 220 or the right side plate 230, making the left side plate 220 or the right side plate 230 less prone to bending. It can be understood that the second reinforcing block 250 can be a metal part or a plastic part with a large thickness.

[0067] It should be noted that, for the reinforcing ribs or reinforcing blocks in the above embodiments, they can be integral with the base plate body 100, injection molded together with the base plate body 100, integrally molded by metal die casting, or injection molded as inserts together with the base plate body 100.

[0068] Reference Figure 1As shown, in some embodiments, a crossbeam structure can be provided at the edge of the base plate assembly 1000, for example, a crossbeam can be arranged at the front, left or right edge of the base plate body 100. Alternatively, a crossbeam can be provided at the rear edge of the upper side plate 240. These crossbeam structures can be understood as flange structures. For example, the front of the base plate body 100 is provided with a first flange 160, the right side of the base plate body 100 is provided with a second flange 170, the left side of the base plate body 100 is provided with a third flange 180, and the rear side of the upper side plate 240 is provided with a fourth flange 241. These crossbeam structures are mainly used to connect with the side plates of the housing or with the compressor base plate. The first flange 160, the second flange 170, the third flange 180 and the fourth flange 241 can be understood as being processed with the base plate assembly 1000 through a bending process or an integral molding process, which can save the number of parts and achieve a high degree of integration.
