[0038] Please refer to Figures 1 to 8 The present application provides a refrigerator lower rib plate assembly 100, which is applied to a refrigerator, mainly used for connecting and structurally supporting the bottom plate of the refrigerator and components such as compressors, and by increasing the structural strength of the structure, it can meet the structural requirements of modern refrigerators.

[0039] As Figure 1 shown, the refrigerator lower rib plate assembly 100 includes a base 10, a reinforcing lining 20 and a lower rib plate 30, wherein the base 10 has opposite front side 11 and rear side 12, the base 10 includes a first plate body 13 lying flat and a second plate body 14 standing, the second plate body 14 is connected to the front side 11 of the first plate body 13, and the rear side 12 of the first plate body 13 is used to connect the refrigerator bottom plate assembly 102. The first plate body 13 and the second plate body 14 are not strictly limited to flat plates, only express their general overall shape, according to the processing and assembly requirements, can be with reinforcing ribs, flanges, local deformation, etc., wherein the standing and the lying are understood as the relative extension direction of the two plate bodies in the use state of the refrigerator, and are not strictly limited to the angle relationship with the horizontal plane.

[0040] The reinforcing lining 20 is attached to the connecting part of the first plate body 13 and the second plate body 14, and the top edge 141 of the second plate body 14 is a combination part 21 that is higher than the reinforcing lining 20. The transition part between the first plate body 13 and the second plate body 14 is more prone to stress deformation, and the reinforcing lining 20 and the first plate body 13 and the second plate body 14 both have fixed parts, which can better inhibit the deformation between them.

[0041] The lower rib plate 30 is bent to form a first mounting groove 31 and a second mounting groove 32, the first mounting groove 31 is downwardly open and is inserted into the joint 21, and the second mounting groove 32 is upwardly open and is used to connect the refrigerator liner 101. The bending of the lower rib plate 30 can further improve the strength of the lower rib plate 30, and the two mounting grooves can be inserted into the surrounding components, which is more convenient for assembly and compensates for the processing error.

[0042] It should be explained that the existing refrigerator lower rib plate assembly 100 is usually composed of a simple sheet metal part or a thin iron sheet metal combined with a hollow plastic plate, which has weak structural strength and poor connection strength between the components. During the transportation or fixing process, the refrigerator lower rib plate assembly 100 is prone to cracking or deformation. In the present application, the refrigerator lower rib plate assembly 100 with large structural strength and less deformation is formed by the combination of the base 10, the reinforcing liner 20 and the lower rib plate 30. The first mounting groove 31 of the lower rib plate 30 is downwardly open and can be inserted into the joint 21 on the base 10, so as to fix the reinforcing liner 20 on the base 10, which makes the connection structure of the assembly more stable and less likely to crack, and meets the structural requirements of modern refrigerators.

[0043] Here, the base is made of plastic material, and the thickness of the base is set to 2.3mm-2.7mm. The plastic material is easy to form, has small density and good heat preservation performance, which can improve the performance of the refrigerator and save the production cost of the refrigerator. The thickness of the base can be set to 2.3mm, 2.4mm, 2.5mm, 2.6mm or 2.7mm, but is not limited thereto, and can be determined according to the specific use. In the present embodiment, the thickness of the base is set to 2.5mm.

[0044] As preferred, the rear side 12 of the base 10 is provided with a motor wire hole, which can facilitate the after-sales maintenance of the refrigerator.

[0045] As shown in FIGS. 1, 2 and 3, the first plate body 13 is provided with a reinforcing liner 20, which is arranged on the top surface of the first plate body 13 and is used to reinforce the first plate body 13. Figure 1 Figure 4 As shown in FIGS. 1, 2 and 3, the first plate body 13 is provided with a reinforcing liner 20, which is arranged on the top surface of the first plate body 13 and is used to reinforce the first plate body 13.

[0046] Further, the number of the two parts of the fireproof cover 131 is one or more, which can be one, two or four, but is not limited thereto, and the specific number can be determined according to the actual use. In the present embodiment, the number of the two parts of the fireproof cover 131 is one.

[0047] ​Here, the fireproof cover 131 is made of metal sheet to increase the structural strength of the whole assembly.

[0048] For example, the first plate body 13 is provided with a raised area 132 for avoiding other components on the bottom side, and the two parts of the fireproof cover 131 are arranged on the two sides of the raised area 132 respectively. The raised area 132 can avoid other components of the refrigerator such as the push rod assembly and the motor. In this embodiment, the other components are the push rod assembly for assisting the opening and closing of the refrigerator door, which is inserted into the raised area through a guide structure and fixed by screws.

[0049] Preferably, the lower rib assembly 100 of the refrigerator is provided with a wind deflector, and the base 10 and the fireproof cover 131 are further provided with uniformly arranged small holes. The wind deflector is installed on the base 10 by screws, and the small holes and the wind deflector are used for heat dissipation, air permeation and foaming sealing.

[0050] As shown in Figures 1 to 6 The second plate body 14 has opposite inner side 142 and outer side 143, the inner side 142 of the second plate body 14 is limitedly connected to the reinforcing liner 20, and the outer side 143 is provided with a first tongue 144 clamping and limiting the bottom edge of the lower rib 30. The first tongue 144 on the second plate body 14 can limit the lower rib 30, so that the structural connection between the lower rib 30 and the base 10 is more firm.

[0051] For example, the base 10 is further provided with a second tongue 145, the second tongue 145 is arranged on the first plate body 13, and the second tongue 145 is bent to form a first positioning groove 1451 with the opening downward, the first folding edge 1311 of the fireproof cover 131 is inserted into the first positioning groove 1451, so that the fireproof cover 131 can be limited on the base 10, and the installation is more firm, so as to increase the structural stability of the lower rib assembly 100 of the refrigerator.

[0052] Further, the base 10 is further provided with a second positioning groove 1452, the second positioning groove 1452 is arranged on the rear bottom of the first plate body 13, and is used for positioning and connecting the refrigerator bottom plate assembly 102.

[0053] Preferably, the two sides of the second plate body 14 in the horizontal direction are arranged with first connecting holes 146 for penetrating fasteners, which can be fixedly connected with the reinforcing liner 20 and other components of the refrigerator by screws.

[0054] For example, the reinforcing liner 20 is made of metal sheet, and is arranged on the inner side of the second plate body 14, so as to stably connect the reinforcing liner 20 with the base 10, strengthen the whole structure of the lower rib assembly 100 of the refrigerator, and support the lower rib 30 and the base 10, and is not easy to deform.

[0055] Further, the thickness of the reinforcing pad 20 can be set to a range of 1.4mm-1.6mm to reduce the production cost while ensuring the structural rigidity of the reinforcing pad 20. The thickness of the reinforcing pad 20 can be 1.4mm, 1.45mm, 1.5mm, 1.55mm, 1.6mm, but is not limited thereto and can be determined according to the specific use. In the embodiment, the thickness of the reinforcing pad 20 is set to 1.5mm.

[0056] As shown in Figure 1 and Figure 7 , the reinforcing pad 20 includes a third plate body 22 and a fourth plate body 23, wherein the third plate body 22 is fixedly attached to the top surface of the first plate body 13, and the fourth plate body 23 is connected to the front edge of the third plate body 22 and fixedly attached to the inner side of the second plate body 14. The fourth plate body 23 has a gap 231 between the two side edges in the horizontal direction and the third plate body 22, and the two side edges are provided with second connecting holes 232 matched with the first connecting holes 146. The gap 231 between the third plate body 22 and the fourth plate body 23 is provided to allow the two to have a deformation space allowing movement, which can compensate for the machining and assembly errors of the components at this position. The second connecting holes 232 and the first connecting holes 146 can be connected by thread or other structures to increase the strength of the connecting structure.

[0057] In combination with Figure 3 and Figure 8 , the lower rib plate 30 is made of metal sheet metal parts, which can increase the strength of the lower rib plate 30 components, so as to further increase the structural strength of the refrigerator lower rib plate assembly 100.

[0058] Further, the top of the reinforcing pad 20 is bent to form a stepped structure 24, the second mounting groove 32 of the lower rib plate 30 is located on the inner side of the second plate body 14, and the part of the lower rib plate 30 for forming the second mounting groove 32 is located directly above and adjacent to the stepped structure 24. The stepped structure 24 not only can improve the strength of the top of the reinforcing pad 20, but also can play a supporting and limiting role when the lower rib plate 30 has a tendency to deform.
