Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a bracket structure, a lower bottom plate assembly and a refrigerator. Background Art

[0002] The lower bottom plate assembly of a refrigerator is welded by a sheet metal bottom plate, a left bracket, a right bracket, a left bracket reinforcing iron, a right bracket reinforcing iron and a feed port rebound sheet. Among them, the sizes of the left and right brackets are closely related to the model of the compressor used in the refrigerator. With the iterative upgrade of refrigerator products, the models of refrigerator compressors tend to be diversified. Generally, the refrigerator industry changes the component size by opening a new sheet metal mold for different compressor models. By changing the part sizes of the left and right brackets, a suitable compressor installation space is formed in the assembly to meet the installation requirements of different models of compressors. Different-sized molds need to be made for the left and right bracket parts in the lower bottom plate assembly, which further increases the production cost of the lower bottom plate assembly. At the same time, when the left and right brackets are welded to the bottom plate, the circular bosses on the bottom plate are used to cooperate with the circular punching holes on the left and right brackets for shape positioning. The form tolerance of the bosses is ±0.3mm, and the tolerance of the punching holes is ±0.1mm. The positioning accuracy is poor when the two cooperate, and the positioning stability of the two parts directly affects the quality of the assembly.

[0003] The applicant of the present invention has found that the prior art has at least the following technical problems:

[0004] 1. New sheet metal molds for the left and right brackets: When producing the left and right brackets, different sheet metal molds are made for different compressor models, and they cannot be borrowed among different refrigerator models. Under the premise of product diversity, this method results in more mold cost investment and mold management investment, which is not conducive to the cost control of refrigerators.

[0005] 2. Shape positioning of the circular bosses on the bottom plate: This structure uses the circular bosses on the bottom plate to cooperate with the circular punching holes on the left and right brackets to achieve the effect of assisting welding positioning. During the production process, the employees perform welding after visual comparison. During this process, due to the instability of the structure cooperation, the consistency of the welding quality cannot be guaranteed. At the same time, the operation time also increases because the employees adjust the cooperation effect of the circular bosses and the holes, resulting in low production efficiency. The outer contour size of the bosses is 3mm ± 0.3mm, and the punching size is 5 ± 0.1mm. There is a moving space of 2.4mm during actual production. Content of the Utility Model

[0006] The purpose of the utility model is to provide a bracket structure, a lower bottom plate assembly and a refrigerator to solve the technical problems of high number and high cost of mold making for the left and right brackets in the prior art.

[0007] To achieve the above object, the utility model provides the following technical solutions:

[0017] When there are more than one layer of installation holes, that is, when installation holes are provided in at least two installation positions, and only one layer of installation holes can be used during assembly, the other unused layers of installation holes need to be blocked to prevent the leakage of foam. It should be noted that the structure of the hole-blocking member is not specifically limited here, as long as it can block the holes.

Specific embodiments

[0049] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts fall within the scope protected by the present utility model.

[0050] As Figures 1-4 shown, the present utility model provides a support structure, including a flat plate-type support body, and the support body has an installation space 60 and an installation area 10 located on the periphery of the installation space 60; at least two layers of installation positions are arranged side by side from the inside to the outside in the installation area 10, and an installation hole 50 is opened in one of the installation positions for connecting with a component to be installed.

[0051] In the support structure of the present utility model, several optional installation holes are designed on the left and right supports, and different installation holes are selected according to the external dimensions of the compressor to realize the flexible application of the parts. At the same time, due to the selectivity of the installation holes, the unselected installation holes are not punched on the parts, and there is no need to increase foaming and leak plugging.

[0052] It should be noted here that in this embodiment, the component to be installed can be the bottom plate 3 in the lower bottom plate assembly of the refrigerator, and support structures are provided on both sides of the bottom plate 3. In this embodiment, the support structures on both sides of the bottom plate 3 are respectively called the left support 1 and the right support 2.

[0053] The structures of the left support 1 and the right support 2 are completely the same.

[0054] The bracket structure provided by the present utility model sets at least two layers of mounting positions in the mounting area 10 outside the mounting space 60, and the mounting positions are arranged side by side from the inside to the outside to form different mounting heights. By setting a mounting hole 50 in one of the mounting positions for connecting with the bottom plate 3 in the lower bottom plate assembly, the adjustment of the mounting height of the bottom plate 3 can be realized to adapt to compressors of different specifications. This structure can effectively reduce the number of left and right bracket molds, and at the same time effectively solve the inconvenience of the welding and installation operation of the bottom plate assembly, and effectively improve the assembly installation efficiency and positioning stability.

[0055] During use, the mounting hole 50 can be opened in the corresponding mounting position according to the specification of the bottom plate 3, without opening the mounting hole 50 in all the mounting positions. This method realizes the setting of the mounting hole 50 as needed, not only without re-opening the mold of the bracket structure, but also improving the applicable range of the bracket structure to meet the placement of compressors of different specifications.

[0056] As an optional implementation manner of the present utility model, the number of mounting positions is three layers, namely a low mounting position 20, a middle mounting position 30 and a high mounting position 40. As Figure 2 shown, when the component to be installed is of small size, the mounting hole 50 is opened in the low mounting position 20; as Figure 3 shown, when the component to be installed is of medium size, the mounting hole 50 is opened in the middle mounting position 30; as Figure 4 shown, when the component to be installed is of large size, the mounting hole 50 is opened in the high mounting position 40.

[0057] The low, middle and high here are relative. When the bottom plate 3 is installed in the high mounting position 40, the mounting space 60 enclosed between the bottom plate 3, the left bracket 1 and the right bracket 2 is larger and higher, suitable for compressors with larger specifications; when the bottom plate 3 is installed in the middle mounting position 30, the mounting space 60 enclosed between the bottom plate 3, the left bracket 1 and the right bracket 2 is slightly larger and slightly higher, suitable for compressors with medium specifications; when the bottom plate 3 is installed in the low mounting position 20, the mounting space 60 enclosed between the bottom plate 3, the left bracket 1 and the right bracket 2 is smaller and shorter, suitable for compressors with smaller specifications. Of course, the large, medium, small, high and low mentioned here are all relative and do not represent a certain numerical range.

[0058] The bracket structure of the present utility model can adjust the position of the mounting hole 50 according to the size of the component to be installed, solves the current process situation that the left and right bracket parts need to be molded corresponding to different models of compressors during the production of the refrigerator lower bottom plate assembly, increases the flexible application of the left and right bracket parts, and reduces the mold manufacturing and management costs.

[0059] Furthermore, in this embodiment, the mounting hole 50 is opened in at least two layers of mounting positions.

[0060] With this structural arrangement, multiple mounting holes 50 can be set up at one time, reducing the on-site hole-opening steps. However, after installation, there is a need to seal the unused mounting holes 50.

[0061] As another alternative embodiment of the present utility model, mounting holes 50 are provided in all mounting positions.

[0062] With this structural arrangement, all the mounting holes 50 can be punched out at one time, with high processing efficiency and all the holes can be punched simultaneously at one time. However, it is necessary to seal the unused holes after installation.

[0063] As a further improvement of the present utility model, it further includes a hole-blocking member detachably disposed in the installed area 10 for blocking some of the mounting holes 50.

[0064] When there is more than one layer of mounting holes 50, that is, when mounting holes 50 are provided in at least two mounting positions, and only one layer of mounting holes 50 can be used during assembly, the other unused layers of mounting holes 50 need to be blocked to prevent the foam from leaking. It should be noted that the structure of the hole-blocking member is not specifically limited here as long as it can block the holes.

[0065] As a further improvement of the present utility model, the hole-blocking member is made of aluminum foil, such as an aluminum foil sheet.

[0066] The size of the aluminum foil sheet can be selected according to needs. For example, multiple aluminum foil sheets can be provided, and each aluminum foil sheet blocks all the mounting holes 50 in one layer of the mounting position.

[0067] As Figures 1-4 shown, in this embodiment, the installation area 10 has an L-shaped structure and is located at the top and front of the bracket body respectively.

[0068] Specifically, the installation area 10 is located at the top and front of the left bracket 1 and the right bracket 2 respectively. To simplify the structure, the position between the top and front of the left bracket 1 and the right bracket 2 is a bevel structure, which not only saves materials and reduces costs but also avoids sharp corner structures.

[0069] Through the L-shaped installation area 10, an L-shaped installation structure can be formed, providing installation limits in the horizontal and vertical directions respectively, improving the assembly stability of the components, and ensuring stability during welding.

[0070] As a further improvement of the present utility model, the number of mounting holes 50 in one installation area 10 is at least two, and they are arranged at intervals along the extension direction of the installation area 10.

[0071] By installing at at least two points, the connection stability between the bracket body and the bottom plate 3 can be ensured.

[0072] As shown Figures 1-4 In the figure, as a further improvement of the present utility model, the number of mounting holes 50 in a mounting area 10 is three, which are respectively arranged at both sides and the connection part of both sides of the mounting area 10.

[0073] Specifically, the mounting holes 50 in the mounting area 10 include horizontal holes, inclined holes and vertical holes. The horizontal holes are located at the tops of the left bracket 1 and the right bracket 2, the inclined holes are located at the inclined surface structure, and the vertical holes are located at the front parts of the left bracket 1 and the right bracket 2.

[0074] By arranging three mounting holes 50 in each mounting area 10 to form an L-shaped mounting structure, the limiting is carried out respectively from the vertical direction and the horizontal direction to ensure the connection stability and facilitate the welding operation.

[0075] As shown Figure 1 In the figure, as a further improvement of the present utility model, a pressing plate part 6 is vertically extended from the bottom of the bracket body.

[0076] By arranging the pressing plate part 6, it is used for the placement and limiting fixation of the U-shaped reinforcing iron.

[0077] As shown Figure 1 In the figure, as a further improvement of the present utility model, a U-shaped stopper part 7 is vertically extended outward from the rear part of the bracket body.

[0078] By arranging the stopper part 7, it is convenient for the limiting at the rear side of the U-shaped reinforcing iron.

[0079] As shown Figures 5-8 In the figure, a lower bottom plate assembly provided by the present utility model includes a bottom plate 3, a reinforcing iron and a bracket structure; wherein:

[0080] The bracket structure includes a left bracket 1 and a right bracket 2;

[0081] The left bracket 1 and the right bracket 2 are respectively arranged on the left and right sides of the bottom plate 3;

[0082] The reinforcing iron includes a left bracket reinforcing iron 4 and a right bracket reinforcing iron 5;

[0083] Plug-in parts 8 for plugging and connecting with the mounting holes 50 are respectively arranged on the left and right sides of the bottom plate 3;

[0084] The reinforcing iron is pressed between the bracket structure and the bottom plate 3.

[0085] Specifically, the left bracket reinforcing iron 4 is pressed on the pressing plate part 6, the stopper part 7 of the left bracket 1 and the bottom plate 3; the right bracket reinforcing iron 5 is pressed on the pressing plate part 6, the stopper part 7 of the right bracket 2 and the bottom plate 3;

[0086] In this embodiment, both the left bracket reinforcing iron 4 and the right bracket reinforcing iron 5 are L-shaped structures and the cross section is U-shaped.

[0087] The lower bottom plate assembly provided by the utility model adopts a bracket structure that can be flexibly applied, enabling the lower bottom plate assembly to meet the installation requirements of compressors of different models, saving production costs. By setting the insertion part 8 and the installation hole 50 for limit connection, it is not only easy to assemble, has high stability, but also has high strength, can meet the requirements for positioning stability during the welding process, reduces the operation time of employees, improves product quality, and enhances production efficiency.

[0088] As a further improvement of the utility model, as Figure 5 shown, the number of the insertion parts 8 is three, which are respectively arranged corresponding to the three installation holes 50 in the same installation position.

[0089] The bottom plate of the utility model is designed with an insertion part 8 that can be optionally installed with the left and right brackets. After the bottom plate is inserted into the left and right brackets, the flanging of the insertion part 8 of the bottom plate is carried out, and then the component is welded. Through the line-surface contact between the side lines of the optional installation holes of the left and right brackets and the insertion part of the bottom plate, stable positioning is achieved, and at the same time, the time for employees to adjust the matching effect is reduced, and the production efficiency is improved.

[0090] The bottom plate 3 is also provided with a flanging part 9 for limiting the insertion depth. Specifically, the flanging part 9 is located between the two insertion parts 8. When the bottom plate 3 is installed with the left bracket 1 and the right bracket 2, the insertion part 8 is inserted through the installation hole 50 and then folded 90 degrees to fit on the outer wall of the left bracket 1 or the right bracket 2; at this time, the flanging part 9 just fits tightly with the inner wall of the left bracket 1 or the right bracket 2, so as to realize the limitation of the insertion depth of the insertion part 8.

[0091] For the lower bottom plate assembly of the utility model, the left and right bracket parts realize stepped changes in part sizes by adding optional installation holes 50, meet the changing requirements of the installation space 60 of different compressors, effectively reduce the mold manufacturing of the left and right bracket parts, and reduce the mold manufacturing cost and management cost. At the same time, this structure realizes stable positioning through the cooperation of the openings of the left and right brackets and the flanging structure of the bottom plate 3, reduces the visual comparison operation time of employees, improves efficiency, and improves the consistency of welding quality.

[0092] A refrigerator provided by the utility model includes the above-mentioned lower bottom plate assembly.

[0093] When the lower bottom plate assembly of the present utility model is assembled, the original lapping method of the bottom plate is changed to plug-in + lapping. The left and right brackets have multiple groups of selectable punching holes, optimizing the original flanging lapping process of the bottom plate. First, the plug-in part of the bottom plate is inserted into the optional mounting holes (punching hole groups) on the left and right brackets, and then the flanging and bending of the plug-in part of the bottom plate are carried out. Structurally, the bottom plate restricts the freedom degree of the left and right brackets in the horizontal direction through the flanging part and the plugged-in part, and at the same time, through the mounting holes on the left and right brackets, further restricts the freedom degree of the bottom plate in the vertical direction after the flanging and bending of the plug-in part of the bottom plate, achieving effective line-plane contact limiting. After the above installation is completed, the subsequent spot welding work is carried out to complete the final installation and fixation of the lower bottom plate assembly.

[0094] The limiting of the freedom degrees in the horizontal and vertical directions here means that the mounting holes are arranged on multiple side parts to form an L-shaped structure to achieve the limitation of two freedom degrees.

[0095] In addition, the line-plane contact limiting referred to in this embodiment means that the plane contacts with the inner edge of the mounting hole, which is equivalent to projecting the inner edge of the mounting hole onto the plane to form contact, that is, understood as line contact. At the same time, since the mounting holes on the left and right brackets can be selectively processed or not processed during production, there is no need to specially consider the plugging work of the unused punching holes during foam filling, effectively avoiding problems such as liquid leakage caused by the newly added mounting holes, and at the same time avoiding the redundant tape sealing due to the addition of mounting holes.

[0096] The refrigerator of the present utility model includes a refrigerator lower bottom plate assembly that is easy to assemble, has high stability, and sufficient strength. Due to the differences in the external dimensions of different compressors and the different required installation spaces, in order to meet the installation space requirements, it is necessary to manufacture lower bottom plate assemblies of different sizes for installation. The left and right brackets are the key parts in the lower bottom plate assembly that determine the installation space, and different-sized molds need to be manufactured during production to meet the installation space requirements. Based on lean design and the concept of minimizing unnecessary elements and costs, the present utility model designs multiple groups of selectable mounting holes on the left and right brackets. When installing parts, by replacing different bottom plate parts and selecting different selectable mounting holes, the change of the installation space can be realized. Without opening new molds, by selecting the selectable mounting holes, the installation requirements of the compressor can be met, effectively reducing the number of mold openings for the left and right bracket parts and reducing production costs. This lower bottom plate assembly can meet the requirements for positioning stability during the welding process, reduce the operation time of employees, improve product quality, and enhance production efficiency.
