[0043] The housing provided in this embodiment can be applied to refrigeration equipment, such as refrigerators, freezers, etc. The housing is generally made of sheet metal and plays a role in protecting and supporting the internal structure. For example, the housing of refrigeration equipment is generally made of high-quality steel plate or stainless steel, which has high strength and corrosion resistance and can meet the needs of long-term use.
[0044] After the shell of the refrigeration equipment is made of steel plate or stainless steel into the required shape and size by cutting, bending and welding, the inner liner is made in the shell by foaming process. However, during the foaming process, there are gaps at the bends of the corners of the shell, which is prone to overflow. In the related art, the gaps are generally filled with foam or tape to seal, so as to prevent overflow. However, if foam or tape is used to prevent overflow, the foam or tape will be exposed to the outside, affecting the appearance of the product. The shell structure provided by this embodiment can not only prevent overflow without the need for foam and tape, but also ensure the appearance of the product.
[0045] Combination Figures 1 to 5 As shown, the embodiment of the present disclosure provides a housing, including a first sheet 10 and a second sheet 20, which are relatively bent. Generally, the first sheet 10 and the second sheet 20 are relatively bent to form a right angle. In practical applications, the housing includes a plurality of sheets, the first sheet 10 and the second sheet 20 are two of the sheets, and the structural shape between adjacent sheets in the housing can refer to the first sheet 10 and the second sheet 20. The housing encloses a receiving space by relatively bending a plurality of sheets.
[0046] The first sheet 10 has a first folded edge 101 on its edge; the second sheet 20 is bent together with the first sheet 10 and has a second folded edge 201 on its edge, for defining the accommodating space of the shell; wherein the first folded edge 101 and the second folded edge 201 are adjacent to each other and bent on the same side, an end of the first folded edge 101 is bent to form a first sub-folded edge 102, and an end of the second folded edge 201 abuts against the first sub-folded edge 102 to cover the gap between the first folded edge 101 and the second folded edge 201.
[0047] The first sheet 10 can be regarded as a top plate that encloses the accommodation space, and the second sheet 20 can be regarded as a side plate that encloses the accommodation space. The first sheet 10 and the second sheet 20 are bent relative to each other at a right angle. The first folded edge 101 is bent downward from the edge of the first sheet 10, and the second folded edge 201 is bent to one side from the edge of the second sheet 20. The first folded edge 101 and the second folded edge 201 are adjacent and relatively on the same side, that is, the edges of the first folded edge 101 and the second folded edge 201 are also at a right angle. Among them, the first folded edge 101 and the second folded edge 201 are both rectangular, but in actual application, after the first folded edge 101 and the second folded edge 201 are bent, the adjacent ends overlap, resulting in an uneven corner of the shell, so the ends of the first folded edge 101 and the second folded edge 201 are beveled, so that the ends of the first folded edge 101 and the second folded edge 201 can overlap. In this way, there is a gap between the adjacent edges of the first folded edge 101 and the second folded edge 201.
[0048] In this embodiment, the first sheet 10 and the second sheet 20 are both rectangular, and the structures of the rectangular first sheet 10 and the second sheet 20 are improved. The first end of the first sheet 10 is arranged opposite to the first end of the second sheet 20, and the first end of the first sheet 10 is bent to form a first sub-folded edge 102, and the first end of the second folded edge 201 is in contact with the surface of the first sub-folded edge 102, so that not only the gap between the first folded edge 101 and the second folded edge 201 can be blocked, but also the flatness and aesthetics of the shell appearance can be maintained. When the inner liner is foamed, it can prevent the foaming material from overflowing from the gap between the first end of the first sheet 10 and the second end of the second sheet 20.
[0049] The first end of the first sheet 10 is bent to form a first sub-folded edge 102, which can enhance the structural strength of the first sheet 10 at the first end, and avoid overlapping with the second folded edge 201, which would affect the flatness and aesthetics of the shell corner. It should be noted that the first sub-folded edge 102 is bent from the first sheet 10 toward the housing space of the shell, so that the first sub-folded edge 102 is prevented from being exposed outside the shell.
[0050] After the first sub-fold 102 is bent, the end of the second fold 201 abuts against the first sub-fold 102, and the second fold 201 blocks the gap between the first fold 101 and the second fold 201. In addition, the second fold 201 abuts against the first sub-fold 102, which can further improve the structural strength of the first end of the first fold 101.
[0051] In this embodiment, the end of the second folded edge 201 is abutted against the first sub-folded edge 102, which can not only block the gap between the first folded edge 101 and the second folded edge 201, but also maintain the flatness and aesthetics of the shell appearance. When the inner liner is foamed, it can prevent the foaming material from overflowing from the gap between the first end of the first sheet 10 and the second end of the second sheet 20. It should be noted that the end of the second folded edge 201 is bent in the direction facing the accommodating space of the shell.
[0052] In actual application, the first folded edge 101 and the second folded edge 201 are in the same plane. When the end of the second folded edge 201 overlaps the first sub-folded edge 102, the end of the second folded edge 201 needs to have a certain bending setting to meet the requirement of abutting against the first sub-folded edge 102.
[0053] By using the shell provided by the embodiment of the present disclosure, the end of the first sheet 10 is bent to form a first sub-folded edge 102, which can strengthen the structural strength of the first sheet 10 at the first end. After the first sub-folded edge 102 is bent, the end of the second folded edge 201 abuts against the first sub-folded edge 102, which can not only block the gap between the first folded edge 101 and the second folded edge 201 to prevent overflow; but also can further improve the structural strength at the first end of the first folded edge 101, and improve the flatness and aesthetics of the corner of the shell.
[0054] Optionally, the first sub-folded edge 102 is arranged in parallel with the first folded edge 101 to enhance the structural strength of the end of the first folded edge 101 .
[0055] The first sub-fold 102 is bent inward from the corner of the first fold 101 until the first sub-fold 102 is arranged parallel to the first fold 101, which is equivalent to thickening the first fold 101 through the first sub-fold 102, thereby strengthening the structural strength of the end of the first fold 101. During transportation, installation, etc., if the shell collides and happens to collide with the corner area, the shell of this embodiment is not easy to deform based on the structural design of the first sub-fold 102, that is, the corner of the shell provided by this embodiment has a high anti-deformation ability.
[0056] Optionally, the first sub-folded edge 102 is located on the inner side of the first folded edge 101 and faces the accommodating space of the shell.
[0057] The first sub-folded edge 102 is located inside the first folded edge 101, that is, it can be understood that the first sub-folded edge 102 is folded in the direction of the housing space of the shell, and after folding, it is located on the inner side wall of the first folded edge 101. The first sub-folded edge 102 is hidden inside the shell. In this way, while strengthening the structural strength of the end of the first folded edge 101, the flatness and aesthetics of the shell corner can also be guaranteed.
[0058] Optionally, the first sub-folded edge 102 is triangular.
[0059] The triangular shape of the first sub-folded edge 102 not only helps to ensure its own structural stability and improve its anti-deformation ability, but also can further improve the anti-deformation ability of the end of the first folded edge 101 when folded to the first folded edge 101.
[0060] Optionally, the first sub-folded edge 102 is arranged to fit closely with the first folded edge 101 .
[0061] The first sub-folded edge 102 is arranged to fit with the first folded edge 101, which can be understood as the surface of the first sub-folded edge 102 fits with the surface of the first folded edge 101, which is equivalent to thickening the first folded edge 101, thereby improving the structural strength and deformation resistance of the end of the first folded edge 101.
[0062] In addition, the first sub-folded edge 102 is arranged in close contact with the first folded edge 101, which can also prevent the foaming material from entering the gap between the first sub-folded edge 102 and the first folded edge 101 during the foaming molding process of the inner liner.
[0063] Optionally, in this embodiment, the second folded edge 201 includes: a second sub-folded edge 202, which is bent from the end of the second folded edge 201 and abuts against the first sub-folded edge 102 to cover the gap between the first folded edge 101 and the second folded edge 201. Figure 2 shown.
[0064] The second sub-folded edge 202 is bent from the end of the second folded edge 201 and abuts against the first sub-folded edge 102, which can not only block the gap between the first folded edge 101 and the second folded edge 201, but also further improve the structural strength of the end of the first folded edge 101.
[0065] In addition, the second sub-folded edge 202 is bent from the second folded edge 201 toward the accommodating space of the shell, so that the second sub-folded edge 202 overlaps the inner side of the first sub-folded edge 102, and can also achieve the purpose of hiding while blocking the gap, thereby ensuring the flatness and aesthetics of the corner of the shell.
[0066] The second sub-folded edge 202 is bent in order to better adapt to the thickness dimension of the first sub-folded edge 102 superimposed after being bent from the first folded edge 101 .
[0067] Optionally, the second fold 201 includes: a third sub-fold 203, which is bent from the end of the second fold 201 along the first direction and arranged parallel to the second fold 201; and a fourth sub-fold 204, which is formed by the reverse bending structure of the third sub-fold 203 along the first direction and abuts against the first sub-fold 102 to block the gap. Figure 5 shown.
[0068] In this embodiment, the second folded edge 201 includes a third sub-folded edge 203, and the third sub-folded edge 203 is bent again to form a fourth sub-folded edge 204. The third sub-folded edge 203 is bent toward the inside of the second folded edge 201, and the third sub-folded edge 203 is arranged parallel to the second folded edge 201 after being bent, which can improve the structural strength of the end of the second folded edge 201.
[0069] The fourth sub-folded edge 204 is formed by bending the third sub-folded edge 203 in the opposite direction along the first direction, that is, it can be understood that the second folded edge 201, the third sub-folded edge 203 and the fourth sub-folded edge 204 are similar to a Z-shaped structure.
[0070] After being bent, the fourth sub-folded edge 204 abuts against the first sub-folded edge 102 , thereby covering the gap between the first folded edge 101 and the second folded edge 201 .
[0071] The third sub-fold 203 is bent inward from the corner of the second fold 201 until the third sub-fold 203 is arranged parallel to the second fold 201, which is equivalent to thickening the second fold 201 through the third sub-fold 203, thereby strengthening the structural strength of the end of the second fold 201. During transportation, installation, etc., if the shell collides and happens to collide with the corner area, the shell of this embodiment is not easy to deform at the corner of the shell through the structural design of the third sub-fold 203, and has a high anti-deformation ability.
[0072] Optionally, the third sub-folded edge 203 is located on the inner side of the second folded edge 201 and faces the accommodating space of the shell.
[0073] The third sub-folded edge 203 is located inside the second folded edge 201, that is, it can be understood that the third sub-folded edge 203 is folded in the direction of the housing space of the shell, and after folding, it is located on the inner side wall of the second folded edge 201. The third sub-folded edge 203 is hidden inside the shell. In this way, while strengthening the structural strength of the end of the second folded edge 201, the flatness and aesthetics of the shell corner can also be guaranteed.
[0074] Optionally, the third sub-folded edge 203 is triangular.
[0075] The third sub-folded edge 203 is triangular in shape, which not only helps to ensure its own structural stability and improve its anti-deformation ability, but also can further improve the anti-deformation ability of the end of the second folded edge 201 when folded to the second folded edge 201.
[0076] Optionally, the third sub-folded edge 203 is arranged to fit the second folded edge 201 .
[0077] The third sub-folded edge 203 is fitted with the second folded edge 201, which can be understood as the surface of the third sub-folded edge 203 is fitted with the surface of the second folded edge 201, which is equivalent to thickening the second folded edge 201, thereby improving the structural strength and deformation resistance of the end of the second folded edge 201.
[0078] In addition, the third sub-folded edge 203 is arranged in close contact with the second folded edge 201, which can also prevent the foaming material from entering the gap between the third sub-folded edge 203 and the second folded edge 201 during the foaming molding of the inner liner.
[0079] Optionally, the fourth sub-edge 204 is arranged in parallel with the third sub-edge 203 .
[0080] Optionally, the surfaces of the second folded edge 201, the third sub-folded edge 203 and the fourth sub-folded edge 204 are sequentially fitted together.
[0081] The surfaces of the second folded edge 201, the third sub-folded edge 203 and the fourth sub-folded edge 204 are sequentially fitted, that is, it can be understood that the surface of the second folded edge 201 fits with the surface of the third sub-folded edge 203, and the other surface of the third sub-folded edge 203 fits with the surface of the fourth sub-folded edge 204. This is equivalent to thickening the second folded edge 201, thus improving the structural strength and anti-deformation ability of the end of the second folded edge 201.
[0082] In addition, the second folded edge 201, the third sub-folded edge 203 and the fourth sub-folded edge 204 are arranged in close contact with each other, which can also prevent the foaming material from entering the gaps between them during the foaming molding process of the inner liner.
[0083] Optionally, the bending edge of the first sub-folded edge 102 is arranged opposite to and parallel to the bending edge of the third sub-folded edge 203 .
[0084] The bending edge of the first sub-fold 102 can be understood as the edge opposite to the second fold 201 after the first sub-fold 102 is bent, that is, the bending edge of the first sub-fold 102. Similarly, the bending edge of the third sub-fold 203 can be understood as the edge opposite to the first fold 101 after the third sub-fold 203 is bent, that is, the bending edge of the third sub-fold 203.
[0085] The bending edge of the first sub-folded edge 102 is arranged opposite and parallel to the bending edge of the third sub-folded edge 203, which can avoid interference between the first sub-folded edge 102 and the third sub-folded edge 203, thereby affecting the flatness of the shell corner and the overall aesthetics of the shell.
