Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 3, 4, 5 and 6, the multi-element modular door liner assembly of the present invention includes corner defining members 11 and edge extensions 12. When the refrigerator door liner 100 is formed by splicing, the corner defining pieces 11 are used for defining four corners of the refrigerator door liner 100, and generally, four corner defining pieces 11 distributed at four corners are required for one refrigerator door liner 100; the edge extension pieces 12 are used for extending the side length of the refrigerator door liner 100, and the edge extension pieces 12 are increased or decreased in pairs, so that the refrigerator door liners 100 with different sizes are formed by splicing.

Comparing the specific structure of the refrigerator door liner 100 shown in fig. 4 and 6, the refrigerator door liner 100 shown in fig. 4 has only one pair of edge extensions 12, and the refrigerator door liner 100 shown in fig. 6 has a pair of edge extensions 12 added to the refrigerator door liner 100 of fig. 4, and the side length of the refrigerator door liner 100 can be changed based on the pair increase or decrease of the edge extensions 12. In other words, the refrigerator door liners 100 with different sizes can be spliced by increasing or reducing the number of the edge extending pieces 12, so that the requirements of refrigerator door bodies with different models are met, the number of corresponding jigs can be greatly reduced in the large-scale refrigerator manufacturing process, and the production cost of the refrigerator door liners is effectively reduced.

As shown in fig. 4 and 6, when the multi-element modular door liner assembly according to the present invention is assembled to form the refrigerator door liner 100, two edge extensions 12 that are increased or decreased in pairs are respectively located on two opposite sides of the refrigerator door liner 100, and each edge extension 12 is located between two corner defining pieces 11 on the same side.

The multi-element modular door lining assembly according to the present invention further comprises a central connector tile 13, the central connector tile 13 being adapted to cover a gap formed by the plurality of corner defining members 11 and/or the edge extension members 13 when assembled to form the refrigerator door lining 100. Referring to fig. 5 and 6, when the refrigerator door liner 100 has the edge extensions 12 on the four sides, a hollow gap is formed in the inner area of the refrigerator door liner 100, and the gap needs to be blocked by the middle joint plate 13 to ensure the integrity of the refrigerator door liner 100.

To avoid gaps formed after the components are assembled, the corner defining members 11, the edge extensions 12 and the middle connector tiles 13 of the present invention each have overlapping portions that overlap adjacent corner defining members 11, edge extensions 12 and/or middle connector tiles 13 when assembled to form the refrigerator door liner 100.

Specifically, referring to fig. 1, the corner defining piece 11 has a corner defining piece body 110 for defining two adjacent sides of the refrigerator door liner 100, and the adjacent two inner sides of the corner defining piece body 110 are formed with a first overlapping portion 111 and a second overlapping portion 112, respectively. In the implementation, the first bridging portion 111 and the second bridging portion 112 are offset in height in the thickness direction of the corner defining member 11 itself. Based on this, when there is no side extension 12 between the same side two corner defining pieces 11 of the refrigerator door liner 100, the same side two corner defining pieces 11 can be engaged with each other by the first engaging portion 111 and the second engaging portion 112.

As shown in fig. 2 and 3 or fig. 2 and 5, the edge extension 12 according to the present invention has opposite sides facing the two corner defining members 11 on the same side when the refrigerator door liner 100 is assembled. Referring to fig. 2, the edge extension 12 has an edge extension body 120, the edge extension body 120 having a third strap 121 and a fourth strap 122 on opposite sides of the same side corner defining piece 11, the third strap 121 and the fourth strap 122 being complementary to the first strap 111 and the second strap 112, respectively, of the corner defining piece 11. As such, in the refrigerator door liner 100 having the edge extension 12 shown in fig. 4 or 6, a tight lap joint can be formed between the edge extension 12 and the corner defining piece 11.

Referring to fig. 2 and 5, in this embodiment, a fifth overlapping portion 123 is provided at a side of the edge extension 12 facing a side of the door liner of the refrigerator, and a sixth overlapping portion 130 may be provided at a periphery of the middle connector plate 13, wherein the sixth overlapping portion 130 overlaps the fifth overlapping portion 123.

It is understood that in other embodiments of the present invention, the first overlapping part 111, the second overlapping part 112, the third overlapping part 121, the fourth overlapping part 122, the fifth overlapping part 123 and the sixth overlapping part 130 are designed to achieve reliable overlapping between two adjacent components when the refrigerator door liner 100 is formed by splicing, and the specific form is not limited to the structure shown in the figures, and in other embodiments of the present invention, the overlapping parts may have other forms.

The corner defining members 11, the side extensions 12 and the central connector tiles 13 are all injection moulded in accordance with the invention. Because the corner limiting pieces 11, the side extending pieces 12 and the middle connecting plate 13 are all in fixed shapes, in the specific implementation process, the manufacture of the refrigerator linings 100 of various models can be realized only by three sets of injection molds, and the manufacture cost of the molds can be effectively reduced.

The refrigerator door liner 100 of the present invention is formed by splicing the above-described multi-component modular door liner assembly, and the spliced refrigerator door liner 100 may have different sizes based on the design structure of the multi-component modular door liner assembly.

In order to ensure reliable bonding between the components of the spliced refrigerator door liner 100, the spliced seam positions of the refrigerator door liner 100 are connected by gluing. In the specific splicing and assembling process, the first overlapping part 111, the second overlapping part 112, the third overlapping part 121, the fourth overlapping part 122, the fifth overlapping part 123 and the sixth overlapping part 130 may be provided with a medium such as glue or double-sided tape at the position overlapping with other components to achieve the bonding between objects.

The refrigerator door body comprises the refrigerator door liner. When the refrigerator door body is specifically constructed, the refrigerator door body further comprises an outer shell (not shown in the figure) arranged opposite to the refrigerator door liner and a heat insulation material filled between the outer shell and the refrigerator door liner.

It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.

The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
