Description

Technical Field

[0001] The present invention belongs to the technical field of refrigerators, and specifically provides a display module, a refrigerator door, and a refrigerator. Background Art

[0002] The door of an existing refrigerator generally includes an inner panel and an outer panel, with a foaming space formed between the inner panel and the outer panel. The foaming space is used to be filled with a foaming agent so that the door can achieve a heat insulation function through the foaming agent.

[0003] At present, some refrigerators also install a display screen on the outer panel of the door body, so that the refrigerator can display relevant data of the refrigerator through the display screen, such as the temperature inside the refrigerator, the ambient temperature of the environment where the refrigerator is located, the humidity inside the refrigerator, etc.

[0004] However, during the process of injecting the foaming agent into the door, the foaming agent's expansion pushes outward against the inner and outer panels, causing them to deform and affecting the flatness of the outer panels, particularly the mounting plate on the outer panel used to mount the display. When this mounting plate swells, the display cannot be mounted on the outer panel of the door. When the display cannot be mounted on the outer panel of the door, workers often need to repair the outer panel, wasting manpower, material resources, and time, and reducing production efficiency. Summary of the Invention

[0005] One object of the present invention is to solve the problem in existing refrigerators that a mounting plate of a display screen swells due to foaming, thereby making it difficult to mount the display screen on the mounting plate.

[0006] To achieve the above objectives, the present invention provides a display module in a first aspect, which is suitable for a refrigerator. The display module includes:

[0007] A display screen mounting member, comprising a display screen back panel;

[0008] a module back cover, at least a portion of which is aligned with the display back panel;

[0009] a foaming cavity formed between the display screen mounting member and the module back cover;

[0010] a first tensioning structure, which is provided on a side of the display screen back panel facing the module back housing, and the first tensioning structure is fixedly connected to the display screen back panel or is integrally formed therewith;

[0011] A second tensioning structure and a substrate, the substrate is fixedly connected to the display screen mounting structure or the module back shell, the second tensioning structure is fixedly connected to the substrate or is made as one piece, and the second tensioning structure is tensioned with the first tensioning structure; when the foaming cavity is filled with a foaming agent, the foaming agent forces the substrate to approach the at least a portion of the module back shell, and thereby causes the second tensioning structure to tighten the first tensioning structure to prevent the display screen back panel from bulging outward.

[0012] Optionally, the first tensioning structure includes a plurality of first tensioning hooks arranged at intervals, and the second tensioning structure includes a plurality of second tensioning hooks arranged at intervals, and the first tensioning hooks and the second tensioning hooks are hooked together.

[0013] Optionally, a positioning hole is provided on one of the first and second hooks, and a positioning protrusion is provided on the other of the first and second hooks; the positioning protrusion is embedded in the positioning hole to prevent the first and second hooks hooked together from being misaligned with each other.

[0014] Optionally, a fixing column is further provided on the side of the display screen mounting member facing the module back shell, and at least one through hole is provided on the substrate, and the diameter of the through hole is smaller than the outer diameter of the fixing column; the display module also includes a screw, which passes through the through hole and is tightened together with the fixing column, thereby fixing the substrate and the display screen mounting member together.

[0015] Optionally, an arc-shaped positioning plate is provided on the substrate, and in the direction in which the positioning protrusion is inserted into the positioning hole, the arc-shaped positioning plate is located on one side of the through hole, so that the fixing column gradually approaches the arc-shaped positioning plate as the positioning protrusion is inserted into the positioning hole, and the fixing column can abut against the inner side surface of the arc-shaped positioning plate after the positioning protrusion is inserted into the positioning hole.

[0016] Optionally, at least one of the through holes is distributed at an end portion of the substrate, so that a portion of the substrate corresponding to the tensioning structure is close to the at least a portion of the module back shell under the action of the foaming agent.

[0017] Optionally, the display module further comprises a display screen mounted on the display screen mounting member and aligned with the display screen back panel.

[0018] Optionally, the display module further comprises glass, and the glass is mounted on the display screen mounting member.

[0019] In a second aspect, the present invention provides a door of a refrigerator, wherein the door comprises the display module according to any one of the first aspects.

[0020] Optionally, the door body includes an outer panel and an inner panel, and the module back shell is fixedly connected to the inner panel or is made as one piece.

[0021] In a third aspect, the present invention provides a refrigerator comprising a cabinet, a door, and the display module according to any one of the first aspects, wherein the display module is mounted on the cabinet.

[0022] In a third aspect, the present invention provides a refrigerator comprising a cabinet and the door described in the second aspect.

[0023] Based on the foregoing description, those skilled in the art will understand that, in the aforementioned technical solution of the present invention, by disposing a first tensioning structure, a second tensioning structure, and a substrate between the display backplate and the module backshell, the display backplate is prevented from bulging when the foaming cavity of the display module foams, thereby ensuring the flatness of the display backplate and, in turn, ensuring the installation of the display backplate with the display. Specifically, by fixedly connecting or integrally forming the first tensioning structure with the display mounting member or the side of the display backplate facing the module backshell, the substrate is fixedly connected to the module backshell, the second tensioning structure is fixedly connected or integrally formed with the substrate, and the second tensioning structure is tensioned with the first tensioning structure, the foaming agent filled in the foaming cavity can force the substrate closer to the module backshell, thereby causing the second tensioning structure to tighten the first tensioning structure, thereby preventing the display backplate from bulging outward due to the extrusion of the foaming agent.

[0024] Furthermore, by configuring the first tensioning structure as a plurality of first hooks distributed at intervals, and configuring the second tensioning structure as a plurality of second hooks distributed at intervals, the first tensioning structure and the second tensioning structure can be hooked together through the first hooks and the second hooks.

[0025] Furthermore, by providing a positioning hole on one of the first and second hooks, and providing a positioning protrusion on the other of the first and second hooks, and allowing the positioning protrusion to fit into the positioning hole, the first and second hooks, when hooked together, are prevented from misaligning. This also enhances the connection strength of the first and second hooks when hooked together, preventing them from becoming disengaged due to excessive tension.

[0026] Furthermore, by setting a fixing column on the side of the display screen mounting component facing the module back shell, setting a through hole on the substrate, and passing the screw through the through hole and tightening it together with the fixing column, the substrate and the display screen mounting component are fixed.

[0027] Furthermore, by arranging an arc-shaped positioning plate on the substrate, and making the fixing column gradually approach the arc-shaped positioning plate as the positioning protrusion is inserted into the positioning hole, the fixing column can abut against the inner side surface of the arc-shaped positioning plate after the positioning protrusion is inserted into the positioning hole, so that the fixing column and the through hole, and the positioning hole and the positioning protrusion can be matched together at the same time with the help of the arc-shaped positioning plate, which facilitates the workers to assemble the display module.

[0028] Furthermore, by distributing at least one through hole at the end of the substrate, the portion of the substrate corresponding to the second tensioning structure can have a certain degree of freedom, so that the portion can be close to or even close to the module back shell under the action of the foaming agent, thereby allowing the first tensioning structure and the second tensioning structure to tighten the back panel of the display screen.

[0046] The display module of the present invention is suitable for a refrigerator. The display module of the present invention includes a display screen mounting member, a module back shell, a foaming cavity, a first tensioning structure, a first tensioning structure, a second tensioning structure, and a substrate. The display screen mounting member includes a display screen back panel. At least a portion of the module back shell is aligned with the aforementioned display screen back panel. The foaming cavity is formed between the aforementioned display screen mounting member and the aforementioned module back shell. The first tensioning structure is provided on the side of the aforementioned display screen back panel facing the aforementioned module back shell, and the aforementioned first tensioning structure is fixedly connected to the aforementioned display screen back panel or is integrally formed.

[0049] like Figures 1 to 4 As shown, in some embodiments of the present invention, the display module 100 includes a display screen mounting member 101, a module back shell 102, a first tensioning structure 103, a second tensioning structure 104, a substrate 105, optional screws 106, an optional display screen 107, an optional glass 108, an optional side panel 109 and an optional handle 110.

[0050] like Figure 5 As shown, in some embodiments of the present invention, the display module 100 further defines a foaming cavity 111 .

[0051] like Figure 1 、 Figure 3 and Figure 6 As shown, the display screen mounting member 101 includes a display screen back plate 1011 for mounting the display screen 107 . Furthermore, a fixing post 1012 is provided on a side of the display screen mounting member 101 facing the module back shell 102 , and the fixing post 1012 is used to fix the substrate 105 .

[0052] like Figure 6 As shown, there are four fixing posts 1012, and the four fixing posts 1012 are distributed at both ends of the display screen back panel 1011. Preferably, each fixing post 1012 corresponds to a corner of the display screen back panel 1011. In addition, those skilled in the art can also set the fixing posts 1012 to any other feasible number as needed, for example, one, two, three, five, six, etc. Further, those skilled in the art can also set multiple fixing posts 1012 at any other feasible position on the display screen back panel 1011 as needed, for example, setting multiple fixing posts 1012 evenly on the display screen back panel 1011, or setting multiple fixing posts 1012 in the middle of the display screen back panel 1011.

[0053] like Figure 1 、 Figures 3 to 5 As shown, the module back shell 102 is fixed relative to the display screen mounting member 101. Specifically, the module back shell 102 and the display screen mounting member 101 can be fixed together using a direct fixed connection method (such as a snap connection, screw connection, adhesive bonding, etc.), or they can be fixed relative to each other through other components of the display module 100 (such as the side panels 109 and / or the handle 110). Furthermore, at least a portion of the module back shell 102 is aligned with the display screen back panel 1011 so that the module back shell 102 is compatible with the substrate 105 through this at least a portion. Preferably, this at least a portion of the module back shell 102 is capable of abutting the substrate 105.

[0054] For the convenience of description, the at least one portion of the module back shell 102 is referred to as a plate-shaped portion hereinafter.

[0055] like Figure 1 、 Figure 3 and Figure 5 As shown, the first tensioning structure 103 is provided on the side of the display screen back panel 1011 facing the module back housing 102, and the first tensioning structure 103 is fixedly connected or integrally formed with the display screen back panel 1011. The fixed connection method can be any feasible connection method such as screw connection, clamping, bonding, etc.

[0056] like Figure 6As shown, the first tensioning structure 103 includes a plurality of first hooks 1031 spaced apart from each other, and the plurality of first hooks 1031 are distributed between the plurality of fixing posts 1012. Furthermore, each first hook 1031 is provided with a positioning protrusion 10311, so that the first hook 1031 is engaged with the second tensioning structure 104 via the positioning protrusion 10311, thereby preventing the first hook 1031 from being misaligned with respect to the second tensioning structure 104.

[0057] like Figure 1 、 Figure 5 、 Figure 7 and Figure 8 As shown, the second tensioning structure 104 and the base plate 105 are fixedly connected or integrally formed. The second tensioning structure 104 includes a plurality of spaced-apart second hooks 1041 that mate with the first hooks 1031. Furthermore, the second hooks 1041 are provided with positioning holes 10411 that mate with the positioning protrusions 10311.

[0058] like Figure 5 and Figure 9 As shown, when the display module 100 is assembled, the first hook 1031 and the second hook 1041 are hooked together, and the positioning protrusion 10311 is embedded in the positioning hole 10411 to prevent the first hook 1031 and the second hook 1041 from being misaligned. At the same time, the hooking and embedding between the first hook 1031 and the second hook 1041 also improves the reliability and strength of the connection between the first hook 1031 and the second hook 1041.

[0059] In addition, those skilled in the art may also set the positioning protrusion 10311 on the second hook 1041 and the positioning hole 10411 on the first hook 1031 as needed.

[0060] like Figure 7 and Figure 8 As shown, at least one through hole 1051 is provided on the substrate 105. Preferably, the number of through holes 1051 is the same as the number of fixing posts 1012, so that each fixing post 1012 corresponds to a through hole 1051. Furthermore, the diameter of the through hole 1051 is smaller than the outer diameter of the fixing post 1012.

[0061] When the display module 100 is assembled, the screw 106 passes through the through hole 1051 and is screwed together with the fixing post 1012, thereby fixing the substrate 105 to the display mounting member 101. Specifically, the screw shank of the screw 106 passes through the through hole 1051 and is screwed together with the fixing post 1012, thereby causing the nut of the screw 106 and the fixing post 1012 to clamp the substrate 105.

[0062] Continue reading Figure 7 and Figure 8 , an arc-shaped positioning plate 1052 is provided on the substrate 105, and each through hole 1051 corresponds to a corresponding arc-shaped positioning plate 1052, and the arc-shaped positioning plate 1052 is used to position the fixing column 1012 in the radial direction of the through hole 1051. In addition, those skilled in the art may also configure the arc-shaped positioning plate 1052 for only a portion of the multiple through holes 1051 as needed. Further preferably, the arc-shaped positioning plate 1052 is a semi-annular cylinder coaxial with the through hole 1051. Alternatively, those skilled in the art may also set the arc-shaped positioning plate 1052 to any other feasible structure, such as a U-shaped cylinder, as needed.

[0063] from Figure 7 and Figure 8 It can be seen that in the direction of the positioning protrusion 10311 being inserted into the positioning hole 10411, the arc-shaped positioning plate 1052 is located on one side of the through hole, so that the fixing column 1012 gradually approaches the arc-shaped positioning plate 1052 as the positioning protrusion 10311 is inserted into the positioning hole 10411, and the fixing column 1012 can abut against the inner side surface of the arc-shaped positioning plate 1052 after the positioning protrusion 10311 is inserted into the positioning hole 10411.

[0064] In other words, during assembly of the display module 100, the first hook 1031 and the second hook 1041 are first offset radially relative to the fixing post 1012 to align the positioning protrusion 10311 with the positioning hole 10411. Then, the second tensioning structure 104 and the substrate 105 are moved radially relative to the fixing post 1012 to engage the positioning protrusion 10311 with the positioning hole 10411. As the positioning protrusion 10311 engages the positioning hole 10411, the fixing post 1012 gradually radially engages within the arcuate positioning plate 1052. The substrate 105 and the fixing post 1012 are then tightened together using screws 106, thereby securing the display mounting member 101, the first tensioning structure 103, the second tensioning structure 104, and the substrate 105.

[0065] Optionally, the portion of the substrate 105 corresponding to the second tensioning structure 104 is flexible. Furthermore, although not shown in the figures, in preferred embodiments of some embodiments of the present invention, after the display module 100 is assembled and before the display module 100 is foamed, a gap exists between the substrate 105 and the module back shell 102 (specifically, the plate-shaped portion), allowing this portion of the substrate 105 to approach the module back shell 102 (specifically, the plate-shaped portion), or even to cling to the module back shell 102 (specifically, the plate-shaped portion). This allows the substrate 105 to tighten the display back plate 1011 through the first tensioning structure 103 and the second tensioning structure 104, preventing the display back plate 1011 from bulging outward.

[0066] Return to continue reading Figure 1 and Figure 3 , the display screen 107 is mounted on the display screen back plate 1011. Those skilled in the art will appreciate that, since the display screen 107 is generally flat, the display screen back plate 1011 also needs to have a certain degree of flatness to ensure that the display screen 107 is mounted on the display screen back plate 1011.

[0067] like Figures 1 to 3 As shown, the glass 108 is mounted on the display screen mounting member 101 and is located outside the display screen 107 to protect the display screen 107 .

[0068] Continue reading Figures 1 to 3 The display module 100 is provided with a side panel 109 at each end. The side panel 109 is used to fix the display screen mounting member 101 and the module back shell 102 together. The side panel 109 and the display screen mounting member 101 and / or the module back shell 102 can be connected together in any feasible manner, such as welding, clamping, screw connection, etc.

[0069] like Figures 1 to 4 As shown, in some embodiments of the present invention, when the display module 100 is applied to a door, for example, a refrigerator door, the display module 100 further includes a handle 110 so that the user can open the corresponding door through the handle 110 .

[0070] like Figure 5 and Figure 9 As shown, a foaming cavity 111 is formed between the display screen mounting member 101 and the module back cover 102 and is used to be filled with a foaming agent 112 .

[0071] Refer to the following Figure 9 The interaction relationship among the display screen back plate 1011 , the fixing column 1012 , the first hook 1031 , the second hook 1041 , the substrate 105 and the foaming agent 112 in some embodiments of the present invention will be described.

[0072] like Figure 9 As shown, after the display module 100 is assembled, the end of the display back plate 1011 and the end of the base plate 105 are fixed together by the fixing column 1012 and the screw 106. The display back plate 1011 and the base plate 105 are pulled together by the first hook 1031 and the second hook 1041.

[0073] When the foaming agent 112 is filled in the foaming cavity 111 and the foaming agent 112 starts to foam, the foaming agent 112 will fill the foaming cavity 111. During the foaming process of the foaming agent 112, a force will be provided to the display back plate 1011 to move away from the substrate 105 (such as Figure 91011 ), providing a force for the substrate 105 to move away from the display back panel 1011 (as shown by the solid large arrow in the foaming agent 112). Figure 9 (as indicated by the large solid arrow in the foaming agent 112 portion).

[0074] At the same time, since the display screen back plate 1011 and the substrate 105 are pulled together by the first hook 1031 and the second hook 1041, the first hook 1031 provides a force for the display screen back plate 1011 to move closer to the substrate 105 (such as Figure 9 As shown by the arrow at the first hook 1031 in the figure, the second hook 1041 provides a force for the substrate 105 to move closer to the display back panel 1011 (as shown by the arrow at the first hook 1031 in the figure). Figure 9 As shown by the arrow at the second hook 1041 in the middle, the first hook 1031 and the second hook 1041 hooked together offset the stress generated by the foaming agent 112, thereby preventing the display back panel 1011 from bulging outward.

[0075] Furthermore, those skilled in the art may also make the portion of the substrate 105 corresponding to the second tensioning structure 104 flexible as needed, so that when the stress generated by the foaming agent 112 during the foaming process is too large, the stress can be released through the flexible deformation of the substrate 105 (bulging toward the side of the module back shell 102), so as to avoid the stress acting on the display back panel 1011 and avoid the display back panel 1011 from bulging outward. To achieve this purpose, the substrate 105 can be made of any feasible material, such as plastic sheet, plastic sheet, metal sheet, metal sheet, etc. In order to reserve deformation space for the substrate 105 to bulge outward, there is a gap between the substrate 105 and the module back shell 102 (such as Figure 9 The gap ranges from 0.5 mm to 5 mm, and preferably, the gap is 1 mm.

[0076] Based on the foregoing description, those skilled in the art will understand that, in some embodiments of the present invention, by arranging a first tensioning structure 103, a second tensioning structure 104 and a substrate 105 between the display screen back panel 1011 and the module back shell 102, the display screen back panel 1011 is prevented from swelling when the foaming cavity 111 of the display module 100 foams, thereby ensuring the flatness of the display screen back panel 1011 and further ensuring the installation of the display screen back panel 1011 and the display screen 107.

[0077] Although not shown in the figures, in other embodiments of the present invention, those skilled in the art may also, as needed, fix the substrate 105 to the module back shell 102 and selectively omit the setting of the fixing column 1012 on the display screen mounting component 101.

[0078] Although not shown in the figures, in some other embodiments of the present invention, those skilled in the art may also configure the first tensioning structure 103 and the second tensioning structure 104 into any other feasible structure as needed. For example, one of the first tensioning structure 103 and the second tensioning structure 104 may be configured as a screw, or one of the first tensioning structure 103 and the second tensioning structure 104 may be configured as a cylinder with a threaded hole.

[0079] Refer to the following Figure 10 and Figure 11 The refrigerators in some embodiments of the present invention are described in detail.

[0080] like Figure 10 As shown, in some embodiments of the present invention, the refrigerator includes a cabinet 210 and a door 220, and the door 220 is pivotally connected to the cabinet 210. Furthermore, the door 220 is also equipped with the display module 100 described in any of the above embodiments.

[0081] like Figure 11 As shown, the door body 220 includes an outer panel 221 and an inner panel 222, with a foaming space formed between the outer panel 221 and the inner panel 222. The display module 100 is embedded in the door body 220. Preferably, the outer surface of the glass 108 of the display module 100 is flush with the outer surface of the outer panel 221. The module back shell 102 of the display module 100 is fixedly connected to the inner panel 222, for example, by welding, riveting, or screwing. Alternatively, those skilled in the art may also form the module back shell 102 and the inner panel 222 as a single piece, or use a portion of the inner panel 222 as the module back shell 102, as needed.

[0082] In addition, in other embodiments of the present invention, those skilled in the art may also install the display module 100 described in any of the above embodiments onto the box 210 as needed.
