The metal layer 31 includes a first side surface 311 and a second side surface 312 that are relatively distributed in the thickness direction X. In the present embodiment, the metal layer 31 includes a thickness direction X, a length direction Y, and a width direction Z, as shown in the figure. Specifically, the thickness direction X, the length direction Y, and the width direction Z of the metal layer 31 are the thickness direction X, the length direction Y, and the width direction Z of the rack assembly 3.

By arranging the first protective layer 32 on the first side surface 311 in the thickness direction X of the metal layer 31 and arranging the second protective layer 33 on the second side surface 312 in the thickness direction X of the metal layer 31, the first protective layer 32, the metal layer 31 and the second protective layer 33 are stacked in sequence, so as to ensure the overall rigidity of the shelf assembly 3, high load-bearing capacity, reduce the weight of the shelf assembly 3, facilitate assembly with other components of the refrigerator 1, and protect the metal layer 31, which is not easy to be damaged. The edges of the first protective layer 32 and the second protective layer 33 extend at the edges of the metal layer 31 and wrap the metal layer 31. In this embodiment, the metal layer 31 is a rectangular plate, and the four peripheral surfaces of the rectangular plate are all wrapped by the edges extended by the first protective layer 32 and the second protective layer 33. In this way, the edge of the metal layer 31 is wrapped by the edge extended by the first protective layer 32 and the second protective layer 33, so as to further protect the metal layer 31 and facilitate the cleaning of the shelf assembly 3. In some embodiments, the distance from the edge extended by the first protective layer 32 and the second protective layer 33 to the edge of the metal layer 31 ranges from 1.5 mm to 3 mm.

[0042] exist Figure 2In the illustrated embodiment, the thickness range of the first protective layer 32 is 1.5 mm-3 mm. In some embodiments, the thickness of the first protective layer 32 may be other values ​​such as 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc., but not limited thereto. With such a configuration, the first protective layer 32 will not cause the overall thickness of the rack assembly 3 to be too thick within this range, and can effectively protect the first side 311 of the metal layer 31. The thickness range of the second protective layer 33 is 1.5 mm-3 mm. In some embodiments, the thickness of the second protective layer 33 may be other values ​​such as 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc., but not limited thereto. With such a configuration, the second protective layer 33 will not cause the overall thickness of the rack assembly 3 to be too thick within this range, and can effectively protect the second side 312 of the metal layer 31. The thickness range of the metal layer 31 is 1 mm-3 mm. In some embodiments, the thickness of the metal layer 31 may be other values ​​such as 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc., but not limited thereto. With such a configuration, the metal layer 31 will not cause the overall thickness of the shelf assembly 3 to be too thick within this range, and can effectively ensure the rigidity of the shelf assembly 3, ensure the load-bearing capacity, and is not easily damaged. The ratio of the thickness of the first protective layer 32 to the thickness of the metal layer 31 is in the range of 0.5-3. In some embodiments, the ratio of the thickness of the first protective layer 32 to the thickness of the metal layer 31 can be 0.5, 1, 1.5, 2, 2.5, 3, etc., but is not limited thereto. With such a configuration, the thickness of the first protective layer 32 to the thickness of the metal layer 31 is in this ratio range, so that the first protective layer 32 can effectively protect the first side 311 of the metal layer 31. The ratio of the thickness of the second protective layer 33 to the thickness of the metal layer 31 is in the range of 0.5-3. In some embodiments, the ratio of the thickness of the second protective layer 33 to the thickness of the metal layer 31 can be 0.5, 1, 1.5, 2, 2.5, 3, etc., but is not limited thereto. In this way, the thickness of the second protective layer 33 and the metal layer 31 is within this ratio range, so that the second protective layer 33 can effectively protect the second side 312 of the metal layer 31. The metal layer 31 is one of aluminum alloy and stainless steel. Specifically, the metal layer can be an aluminum alloy plate or a stainless steel plate. In this embodiment, the metal layer 31 is made of aluminum alloy. In this way, the aluminum alloy material has a low density and is corrosion-resistant, so that the metal layer 31 can reduce weight under the same volume. In some other embodiments, the metal layer 31 is made of stainless steel. In this way, the rigidity of the metal layer 31 is higher, ensuring that more items can be placed on the shelf assembly 3. The first protective layer 32 is a polymer. The second protective layer 33 is a polymer. In this embodiment, the first protective layer 32 can be plastic, and the second protective layer 33 can be plastic. In this way, it is easy to assemble with the box 2 of the refrigerator 1, and there is no need to set other plastic clips on both sides of the shelf assembly 3 to assemble with the box 2, saving manufacturing process, and reducing the places where dirt and grime are hidden in the shelf assembly 3, which is easy to clean.

[0043] Figure 4 FIG. 2 is a cross-sectional view of another embodiment of the rack assembly 3 of the present application. Figure 3 and Figure 4In the illustrated embodiment, the metal layer 31 includes a plurality of through holes 34 that penetrate in the thickness direction X thereof. In the present embodiment, a total of 8 through holes 34 are provided, and other numbers such as 2, 4, 6, etc. may also be provided, without limitation thereto. In the present example, the cross-sections of the plurality of through holes 34 are circular. In some other embodiments, shapes such as elliptical, rectangular, etc. may also be provided, without limitation thereto. The first protective layer 32 and the second protective layer 33 extend into the plurality of through holes 34 and wrap the inner walls of the through holes 34. In the present embodiment, the first protective layer 32 extends in the thickness direction X of the metal layer 31 through the plurality of through holes 34, the second protective layer 33 extends in the thickness direction X of the metal layer 31 through the plurality of through holes 34, and the first protective layer 32 and the second protective layer 33 are fitted in the plurality of through holes 34. With such a configuration, the structure formed by the first protective layer 32, the metal layer 31, and the second protective layer 33 is more stable, improves the stability of the shelf assembly 3, and is not easily damaged. Some of the through holes 34 are spaced apart in the length direction Y of the metal layer 31. In the present embodiment, four through holes 34 can be spaced apart in the length direction Y of the metal layer 31, and other numbers can also be set, not limited thereto. In some embodiments, multiple through holes 34 can be evenly distributed in the length direction Y of the metal layer 31. In this way, the metal layer 31 is more stable with the first protective layer 32 and the second protective layer 33 in the length direction Y, and the rigidity of the rack assembly 3 is more uniform, thereby improving the stability of the rack assembly 3. Some of the through holes 34 are spaced apart in the width direction Z of the metal layer 31. In the present embodiment, two through holes 34 can be spaced apart in the length direction Y of the metal layer 31, and other numbers can also be set, not limited thereto. In some embodiments, multiple through holes 34 can be evenly distributed in the width direction Z of the metal layer 31. In this way, the metal layer 31 is more stable with the first protective layer 32 and the second protective layer 33 in the width direction Z, thereby improving the stability of the rack assembly 3. In the present embodiment, eight through holes 34 are relatively distributed in two rows in the width direction Z of the metal layer 31, wherein each row of through holes 34 includes four through holes 34, and the four through holes 34 are evenly spaced in the length direction Y of the metal layer 31. Some of the through holes 34 among the plurality of through holes 34 are close to the edge of the metal layer 31. With such arrangement, the structure of the shelf assembly 3 close to the edge of the metal layer 31 is more compact. The spacing between two adjacent through holes 34 among the plurality of through holes 34 is 150-250 mm. In the present embodiment, the spacing between two adjacent through holes 34 is 200 mm, and can also be set to 150 mm and 250 mm, but is not limited thereto. With such arrangement, while reducing the influence of rigidity, the combination between the first protective layer 32, the metal layer 31 and the second protective layer 33 is made as compact as possible. The aperture range of the through hole 34 is 4 mm-8 mm.In some embodiments, the aperture of the through hole 34 can be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm or other values, but is not limited thereto. This arrangement facilitates the manufacture of the shelf assembly 3 and ensures that the first protective layer 32 and the second protective layer 33 are effectively combined with the metal layer 31 .
