[0002] In the related art, in the process of manufacturing the support structure, a rivet structure needs to be additionally provided on the carrier, and then the hinge structure on the door body is supported by the rivet structure. In this way, an additional manufacturing process is required, and the rivet structure needs to be additionally prepared, which reduces the manufacturing efficiency of the support structure. SUMMARY

[0003] The present application aims to at least solve one of the technical problems in the prior art.

[0004] To this end, the first aspect of the present application provides a support structure.

[0005] The second aspect of the present application provides a cavity structure.

[0006] The third aspect of the present application provides a dishwasher.

[0007] The fourth aspect of the present application provides a manufacturing method of the support structure.

[0008] The first aspect of the present application provides a support structure for a cavity structure, the cavity structure comprising a cavity body and a door body, the door body being provided with a hinge structure, the support structure comprising: a carrier for connecting the cavity body; a connecting piece provided on the carrier and formed by stamping at least part of the carrier, the connecting piece being used to connect the hinge structure.

[0009] The support structure provided by the present application can be used in the cavity structure and realize the rotational connection between the door body and the cavity body in the cavity structure. The support structure comprises a carrier and a connecting piece. The connecting piece is formed by stamping at least part of the carrier, so that the connecting piece and the carrier are integrated, and the manufacturing process of the connecting piece and the entire support structure is simplified.

[0010] During use of the support structure, the carrier of the support structure is arranged on the cavity body of the cavity structure, and the connecting piece of the support structure is rotationally connected with the hinge structure on the door body, thereby realizing the opening and closing connection between the door body and the cavity body.

[0011] Particularly, in the support structure provided by the present application, the connecting member and the bearing member are in an integrated structure, and the connecting member is directly formed by stamping at least part of the bearing member. In this way, on the one hand, the structural strength of the connecting member and the bearing member can be improved by the integrated structure, thereby reducing the risk of breakage of the connecting member during use of the support structure; on the other hand, the manufacturing process of the support structure can be simplified, especially avoiding the manufacturing process of adding rivets and the like structures on the bearing member in the related art, thereby improving the manufacturing efficiency of the support structure and reducing the materials of the support structure, which is conducive to reducing the cost of the support structure.

[0012] In some possible designs, the bearing member is provided with a through hole; and the connecting member includes a first flange, the first flange being formed at an edge of the through hole and used to connect the hinge structure.

[0013] In this design, the bearing member is provided with a through hole, and the connecting member includes a first flange. In addition, the first flange is formed at an edge of the through hole and protrudes from the side of the bearing member. In this way, during use, the hinge structure can be directly connected through the first flange. Specifically, during the manufacturing of the support structure, the bearing member can be subjected to stamping treatment, thereby forming the through hole on the bearing member; then, the edge of the through hole is subjected to flanging treatment, so as to form a structure connected with the hinge structure through the first flange formed at the edge of the through hole.

[0014] In some possible designs, the first flange and the bearing member are in an integrated structure.

[0015] In this design, the first flange and the bearing member are in an integrated structure. That is, the first flange is formed by deforming part of the bearing member at the edge of the through hole through flanging treatment of the edge of the through hole. In addition, the first flange and the bearing member are in an integrated structure, which on the one hand simplifies the manufacturing process of the connecting member, and on the other hand improves the strength of the first flange, especially the strength of the connection between the first flange and the bearing member, thereby reducing the risk of breakage of the first flange during use of the support structure.

[0016] In some possible designs, the first flange is hollow inside.

[0017] In this design, the first flange is hollow inside. In this way, after the edge of the through hole is subjected to flanging treatment, the first flange can be directly formed. In addition, the hollow inside of the first flange is also conducive to reducing the weight of the entire support structure, while reducing the materials of the support structure.

[0018] In some possible designs, the first flange defines a cylindrical body.

[0019] In the design, the first flange defines a cylinder, and the hinge structure is connected through the cylinder. In particular, during use of the support structure, the hinge structure connected with the first flange rotates with the door body. Therefore, the present application defines a cylinder through the first flange and connects the hinge structure through the cylinder, thereby improving the smoothness of the rotation of the hinge structure and the door body, allowing the user to smoothly open or close the door body, which is beneficial for daily operation.

[0020] In some possible designs, the connecting piece further includes a first arc transition part formed between the first flange and the bearing piece.

[0021] In the design, the connecting piece further includes a first arc transition part. The first arc transition part is formed between the first flange and the bearing piece, and the first arc transition part is an integral structure with the first flange and the bearing piece. In particular, through the arrangement of the first arc transition part, the straight-angle connection at the connection between the first flange and the bearing piece is avoided, and the stress concentration at the connection between the first flange and the bearing piece is also avoided. In addition, the first flange and the bearing piece are smoothly transitioned through the first arc part, thereby reducing the risk of breakage of the support part from the bearing piece during use of the support structure.

[0022] In some possible designs, the connecting piece further includes a second flange provided at an end of the first flange and protruding from a circumferential side of the first flange, and the second flange is used to limit the hinge structure.

[0023] In the design, the connecting piece further includes a second flange. The second flange is provided at an end and protrudes from a circumferential side of the first flange. Specifically, a first end of the first flange is connected to the bearing piece, and a second flange is provided at a second end of the first flange. During use of the support structure, the hinge structure on the door body is sleeved on the first flange through the connecting port and is rotationally connected with the first flange; the second flange is provided at the end of the first flange and can limit the hinge structure to avoid the hinge structure from falling off the first flange.

[0024] In some possible designs, the second flange is an integral structure with the first flange.

[0025] In the design, the second flange is an integral structure with the first flange. That is, the present application directly forms the second flange by flanging the end of the first flange to deform the end of the first flange. In addition, the second flange is an integral structure with the first flange, which on the one hand simplifies the manufacturing process of the connecting piece, and on the other hand improves the strength of the second flange, especially the strength of the connection between the second flange and the first flange, thereby reducing the risk of breakage of the second flange during use of the support structure.

[0026] In some possible design, the connecting piece further comprises a second arc transition part formed between the first flange and the second flange.

[0027] In this design, the connecting piece further comprises a second arc transition part. The second arc transition part is formed between the first flange and the second flange, and the second arc transition part is in an integral structure with the first flange and the second flange. In particular, by arranging the second arc transition part, the right-angle connection of the first flange and the second flange can be avoided, and the stress concentration at the connection of the first flange and the second flange can be avoided. In addition, the first flange and the second flange are smoothly connected through the second arc transition part, and thus the risk of the second flange being broken from the first flange during use of the support structure is reduced.

[0028] In some possible design, the support structure is a metal structure.

[0029] The second aspect of the present application provides a cavity structure, comprising: a cavity body; a support structure according to the first aspect of the present application, the support structure being arranged on the cavity body; and a door body, the door body being provided with a hinge structure, the hinge structure being rotationally connected with the support structure.

[0030] In the cavity structure provided by the present application, the support structure is as described in the first aspect of the present application. Therefore, the cavity structure has all the beneficial effects of the support structure described above, which will not be discussed in detail here.

[0031] In addition, the cavity structure further comprises a cavity body and a door body. The support structure is arranged on the cavity body, and the hinge structure arranged on the door body is rotationally connected with the support structure, so that the door body and the cavity body are rotationally connected.

[0032] In some possible design, the hinge structure is provided with a connecting port, the first flange of the connecting piece is rotationally arranged in the connecting port, and the second flange of the connecting piece is used for limiting the hinge structure.

[0033] In this design, the hinge structure is provided with a connecting port. After the cavity structure is assembled, the hinge structure is clamped to the first flange of the connecting piece through the connecting port, and the rotational connection between the first hinge structure and the support structure is ensured. In addition, the second flange of the connecting piece is located at the side of the hinge structure and effectively limits the hinge structure, so that the risk of the hinge structure falling off the first flange is reduced.

[0034] The third aspect of the present application provides a dishwasher, comprising: a cavity structure according to the second aspect of the present application.

[0035] In the dishwasher provided by the present application, the cavity structure is as described in the second aspect of the present application. Therefore, the cavity structure has all the beneficial effects of the cavity structure described above, which will not be discussed in detail here.

[0036] The fourth aspect of the present application provides a manufacturing method of the support structure, for manufacturing the support structure as the first aspect of the present application, comprising: stamping at least part of the position of the carrier to form the connecting piece on the carrier.

[0037] The manufacturing method of the support structure provided by the present application can manufacture the support structure as the first aspect of the present application. Specifically, in the process of manufacturing the support structure, the present application stamps at least part of the position of the carrier, and then directly forms the connecting piece on the carrier.

[0038] In particular, the present application stamps at least part of the carrier to directly form the connecting piece in an integrated structure with the carrier. In this way, the structural strength of the connecting piece and the carrier can be improved by the integrated structure form, thereby reducing the risk of breaking the connecting piece during use of the support structure; on the other hand, the manufacturing process of the support structure can be simplified, especially avoiding the need for manufacturing processes such as adding rivets and other structures on the carrier in the related art, thereby improving the manufacturing efficiency of the support structure and reducing the materials of the support structure, which is beneficial to reduce the cost of the support structure.

[0039] In some possible designs, stamping at least part of the position of the carrier comprises: punching the carrier to form a through hole on the carrier; and flanging the edge of the through hole to form a first flange of the connecting piece.

[0040] In this design, in the process of stamping at least part of the position of the carrier, the carrier is first punched to form a through hole on the carrier; and then the edge of the through hole is flanged to make the edge of the through hole form and form a first flange. The first flange protrudes from the side of the carrier and can be used to connect the hinge structure on the door body. Specifically, the first flange is hollow inside and defines a cylindrical body to ensure the smooth rotation of the hinge structure.

[0041] Further, in the process of flanging the edge of the through hole, a first transition arc portion can be directly formed between the first flange and the carrier, so that the first flange and the carrier are smoothly transitioned through the first arc portion, thereby reducing the risk of the first flange breaking from the carrier during use of the support structure.

[0042] In some possible designs, stamping at least part of the position of the carrier further comprises: flanging the end of the first flange to form a second flange of the connecting piece.

[0043] In this design, during the stamping process of at least a portion of the bearing member, the end of the first flange can also be flanged to form a second flange at the end of the first flange. The second flange is then used to limit the hinge structure connected to the first flange, preventing the hinge structure from detaching from the support structure.

[0044] Furthermore, during the flanging process of the end of the first flange, a second transition arc portion can be formed directly between the first flange and the second flange, thereby allowing the first flange and the second flange to transition smoothly through the second arc portion, reducing the risk of the second flange breaking off from the first flange during the use of the support structure.

[0045] In some possible designs, the first and second flanges are formed by a single flanging process.

[0046] In this design, the first and second flanges can be formed simultaneously in a single stamping process. This reduces the number of stamping operations in the support structure manufacturing process, thereby simplifying the processing steps and improving the manufacturing efficiency of the support structure.

[0047] In some possible designs, the first and second flanges are formed sequentially through at least two flanging processes.

[0048] In this design, the first and second flanges can be formed separately during the stamping process. That is, only the first flange is formed in the first stamping process, and then the second stamping is performed to form the second flange. This reduces the stamping difficulty and lowers the yield rate of the support structure.

The second circular arc transition portion is formed between the first flange 108 and the second flange 110, and the second transition circular arc portion is an integral structure with the first flange 108 and the second flange 110.

[0092] In particular, by arranging the second transition arc part, the right angle connection of the connection part of the first flange 108 and the second flange 110 can be avoided, and the stress concentration of the connection part of the first flange 108 and the second flange 110 can be avoided.

The support structure 100 is arranged on the cavity body 202, and the hinge structure 206 arranged on the door body 204 is rotationally connected with the support structure 100, thereby realizing the opening and closing connection between the door body 204 and the cavity body 202.

[0100] In this embodiment, further, as shown in Figure 11 The hinge structure 206 is provided with a connecting port 208. After the cavity structure 200 is assembled, the hinge structure 206 is clamped to the first flange 108 of the connecting piece 104 through the connecting port 208, and the rotational connection between the first hinge structure 206 and the support structure 100 is ensured. In addition, the second flange 110 of the connecting piece 104 is located at the side of the hinge structure 206 and effectively limits the hinge structure 206, thereby reducing the risk of the hinge structure 206 falling off from the first flange 108.

[0101] The seventh embodiment of the present application provides a dishwasher comprising the cavity structure 200 of the sixth embodiment of the present application.

[0102] The dishwasher provided in this embodiment comprises the cavity structure 200 of the sixth embodiment of the present application. Therefore, the dishwasher has all the beneficial effects of the cavity structure 200 described above, on the one hand, the structural strength of the connecting piece 104 and the carrier 102 can be improved, thereby reducing the risk of the connecting piece 104 breaking during use of the support structure 100; on the other hand, the manufacturing process of the support structure 100 can be simplified, especially avoiding the manufacturing process of adding rivets and the like structures on the carrier in the related art, thereby improving the manufacturing efficiency of the support structure 100 and reducing the materials of the support structure 100, which is beneficial to reducing the cost of the support structure 100, and will not be discussed in detail here.

[0103] As shown in Figure 12 The eighth embodiment of the present application provides a manufacturing method of a support structure, comprising:

[0104] In step 1202, at least part of the carrier is subjected to stamping treatment to form a connecting piece on the carrier.

[0105] The manufacturing method of the support structure provided by the present application can manufacture the support structure of the first aspect of the present application. Specifically, in the process of manufacturing the support structure, at least part of the carrier is subjected to stamping treatment, thereby directly forming a connecting piece on the support piece.

[0106] Particularly, the present application forms the connecting piece in an integral structure with the carrier through the stamping process on at least part of the carrier. In this way, firstly, the structural strength of the connecting piece and the carrier can be improved through the integral structure, thereby reducing the risk of the connecting piece breaking during use of the support structure. On the other hand, the manufacturing process of the support structure can be simplified, especially avoiding the manufacturing process of adding rivets and the like structures on the carrier in the related art, thereby improving the manufacturing efficiency of the support structure and reducing the materials of the support structure, which is beneficial to reducing the cost of the support structure.

[0107] The ninth embodiment of the present application provides a manufacturing method of a support structure, which is further based on the eighth embodiment and has the following improvements:

[0108] As shown in Figure 6 and Figure 7 , during the stamping process on at least part of the carrier, the carrier is first punched to form a through hole on the carrier. Then, as shown in Figure 8 and Figure 9 , the edge of the through hole is flanged to form a first flange on the edge of the through hole. The first flange protrudes from the side of the carrier and can be used to connect the hinge structure on the door body. Specifically, the first flange is hollow inside and defines a cylindrical body to ensure the smooth rotation of the hinge structure.

[0109] Further, during the flanging process on the edge of the through hole, a first transition arc portion can be directly formed between the first flange and the carrier, so that the first flange and the carrier are smoothly transitioned through the first arc portion, thereby reducing the risk of the first flange breaking from the carrier during use of the support structure.

[0110] The tenth embodiment of the present application provides a manufacturing method of a support structure, which is further based on the ninth embodiment and has the following improvements:

[0111] During the stamping process on at least part of the carrier, the end of the first flange can also be flanged to form a second flange on the end of the first flange, thereby limiting the hinge structure connected to the first flange through the second flange to avoid the hinge structure from separating from the support structure.

[0112] Further, during the flanging process on the end of the first flange, a second transition arc portion can be directly formed between the first flange and the second flange, so that the first flange and the second flange are smoothly transitioned through the second arc portion, thereby reducing the risk of the second flange breaking from the first flange during use of the support structure.

[0113] In the embodiment, the first flange and the second flange can be formed simultaneously by one stamping process during the stamping of the first flange and the second flange. In this way, the number of stamping processes in the manufacturing process of the support structure can be reduced, and the machining process of the support structure is simplified, thereby improving the manufacturing efficiency of the support structure.

[0114] In the embodiment, the first flange and the second flange can be formed respectively by separate stamping processes during the stamping of the first flange and the second flange. That is, only the first flange is formed in the first stamping process, and then the second flange is formed in the second stamping process. In this way, the difficulty of stamping is reduced, and the yield of the support structure is improved.

[0115] In particular, in the related art, a rivet structure is added to the carrier during the manufacturing of the support structure, and the hinge structure on the door body is supported by the rivet structure. In this way, an additional manufacturing process is required, and the rivet structure needs to be prepared additionally, which reduces the manufacturing efficiency of the support structure.

[0116] As shown in Figure 1 , the present application provides a brand-new support structure 100, which can be manufactured by one-piece stamping, thereby simplifying the manufacturing process of the support structure 100 and avoiding the problem of additional material preparation.

[0117] As shown in Figure 1 , the support structure 100 includes a carrier 102 and a connecting piece 104. Further, at least part of the carrier 102 is stamped to form the connecting piece 104, so that the connecting piece 104 and the carrier 102 are integrated.

[0118] Further, the carrier 102 is provided with a through hole 106, and the present application directly flanges the edge of the through hole 106 to form a structure connected with the hinge structure 206 by the first flange 108 formed on the edge of the through hole 106. Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the first flange 108 and the carrier 102 are integrated, thereby improving the strength of the connection between the first flange 108 and the carrier 102. In addition, the first flange 108 is hollow inside, and the first flange 108 defines a cylindrical body, thereby improving the smoothness of the rotation of the hinge structure 206 and the door body 204, so that the user can smoothly open or close the door body 204, which is beneficial for daily operation. Specifically, the first flange 108 and the carrier 102 are smoothly transitioned by the first arc portion, thereby reducing the risk of breakage of the support portion from the carrier 102 during use of the support structure 100.

[0119] Further, as shown in Figure 2 ,Figure 3 、 Figure 4 and Figure 5 As shown in the drawings, the end of the first flange 108 is provided with a second flange 110, and the second flange 110 is arranged on the circumferential side of the first flange 108 and protrudes towards the side. During use of the support structure 100, the hinge structure 206 on the door body 204 is sleeved on the first flange 108 through the connecting port 208 and is rotationally connected with the first flange 108; the second flange 110 is arranged at the end of the first flange 108 and can limit the hinge structure 206 to avoid the hinge structure 206 from falling off the first flange 108. Specifically, the second flange 110 is an integral structure with the first flange 108, thereby improving the strength of the connection between the second flange 110 and the first flange 108. Specifically, the first flange 108 and the second flange 110 are smoothly transitioned through the second circular arc portion, thereby reducing the risk of the second flange 110 breaking off from the first flange 108 during use of the support structure 100.

[0120] Further, during stamping of the above-mentioned first flange 108 and second flange 110, the above-mentioned first flange 108 and second flange 110 can be stamped respectively or can be stamped synchronously at one time.

[0121] In the case of synchronously stamping the above-mentioned first flange 108 and second flange 110 at one time, the number of stamping during manufacturing of the support structure 100 can be reduced, thereby simplifying the processing procedure of the support structure 100 and improving the manufacturing efficiency of the support structure 100.

[0122] In the case of respectively stamping the above-mentioned first flange 108 and second flange 110, the stamping difficulty can be reduced, and the yield of the support structure 100 can be improved.

[0123] Therefore, the support structure 100 provided by the present application can improve the structural strength of the connecting piece 104 and the bearing piece 102, thereby reducing the risk of the connecting piece 104 breaking during use of the support structure 100; on the other hand, the manufacturing procedure of the support structure 100 can be simplified, especially avoiding the manufacturing procedure of adding rivets and the like structures on the bearing piece in the related art, thereby improving the manufacturing efficiency of the support structure 100 and reducing the materials of the support structure 100, which is beneficial to reducing the cost of the support structure 100, and will not be discussed in detail here.
