[0022] Reference Figure 2-Figure 9 , is an embodiment of the packaging structure of the present invention. The packaging structure is disposed in a washing machine to support the outer drum module of the washing machine. The washing machine may be a washing machine, a dryer, a shoe washer, etc.

[0023] See also Figure 4 The packaging structure includes a base 100 and a flexible shell 200 arranged on the base 100.

[0024] like Figure 2 As shown, the base 100 has at least one supporting portion 110 , the supporting portion 110 has an inner cavity 120 with an open top surface, and a material injection hole 130 communicating with the inner cavity 120 is provided on the base 100 .

[0025] The flexible shell 200 is made of a flexible material, such as rubber, silicone, or elastic plastic. The flexible shell 200 has an internal cavity 210 . The flexible shell 200 is fitted over the top opening of the support portion 110 through an injection port, connecting the internal cavity 210 of the flexible shell 200 with the inner cavity 120 to form an injection cavity.

[0026] In this embodiment, a counterweight 400 is provided at the bottom of the outer cylinder module.

[0027] The outer cylinder module is placed on the base 100. Through compression, the flexible shell 200 deforms according to the shape of the counterweight 400, adapting its shape to that of the counterweight 400. This allows the flexible shell 200 to fit snugly against the bottom of the counterweight 400. This deformation of the flexible shell 200 also alters the injection molding cavity, which is then filled with foam material 300. The foam material 300 utilizes its foaming properties to securely bond the flexible shell 200 to the counterweight 400.

[0028] The manufacturing method of the packaging structure is specifically as follows: First, the base 100 is formed by foaming; then, the flexible shell 200 is placed on the support portion 110 of the base 100; and then the outer cylinder module is placed on the packaging structure, such as Figure 6 and Figure 7 As shown, at this time, the flexible shell 200 is deformed due to the squeezing of the counterweight 400 at the bottom of the outer cylinder module; finally, as shown Figure 8 and Figure 9 As shown, the foaming material 300 is injected from the injection hole 130 of the base 100, and the foaming ability of the foaming material 300 is used to tightly combine the flexible shell 200 and the counterweight 400 at the bottom of the outer cylinder module.

[0029] The above-mentioned packaging structure adopts the method of assembly first and then molding, which makes the packaging structure have high structural adaptability and strong versatility; and there is no need to design the packaging in advance, which greatly reduces the time cost of designers; in addition, the foam material 300 is injected after assembly, which can make the whole machine and the packaging structure more tightly assembled, thereby ensuring that the packaging structure is installed in place accurately and correctly, and enhancing the overall stability and protection effect.

[0030] In this embodiment, the base 100 is made of expanded polystyrene (EPS), and the foaming material 300 is made of polyurethane foam (PUFoam). The base 100 is made of expanded polystyrene, which has a low density and high elasticity, providing excellent cushioning performance. The foaming material 300 within the flexible shell 200 is made of polyurethane foam, leveraging its plasticity to tightly integrate the flexible shell 200 with the counterweight 400. The packaging structure of this embodiment utilizes two foaming materials 300 of different densities, thereby providing appropriate cushioning and protection for different parts of the body.

[0031] See also Figure 3 In this embodiment, the outer wall of the support portion 110 is provided with a looped slot 111, and the injection port of the flexible shell 200 is nested within the looped slot 111. Since the flexible shell 200 is made of a flexible material, the injection port of the flexible shell 200 also has a certain degree of elasticity and can be nested within the looped slot 111 of the support portion 110 for fixation, preventing the flexible shell 200 from separating from the support portion 110 during the process of injecting the foaming material 300 into the flexible shell 200.

[0032] In this embodiment, the support portion 110 is a rectangular shell structure with an open top, and the flexible shell 200 is a rectangular shell structure with an open bottom. The bottom opening of the flexible shell 200 forms an injection port. The flexible shell 200 can be a shell structure and can have a specific shape. In other embodiments, the flexible shell 200 can also have a non-specific shape, such as a film bag structure, which is formed into a specific shape after the foaming material 300 is injected.

[0033] In order to ensure that the flexible shell 200 and the foam material 300 inside it will not be taken out when disassembling the device, Figure 3 and Figure 5 As shown, a locking groove 112 is provided on at least one side wall of the support portion 110, which passes through the inner and outer side walls. The locking groove 112 is connected to the injection cavity. The locking groove 112 is a reserved groove. When the foaming material 300 is injected into the injection cavity, the foaming material 300 fills the locking groove 112 to form a foam locking portion 310. Figure 8 and Figure 9 The foam locking portion 310 is embedded and fixed in the locking groove 112, which can prevent the flexible shell 200 and the foam material 300 therein from being taken out when the device is disassembled.

[0034] In this embodiment, the top of the support portion 110 is provided with a flange 113. A locking groove 112 is defined along the bottom surface of the flange 113, located between the sleeve groove 111 and the flange 113. When the flexible shell 200 is sleeved onto the support portion 110, the flange 113 slightly expands the flexible shell 200, forming a constricted structure at the injection port of the flexible shell 200, thereby enabling a tighter connection to the support portion 110 and preventing the two from falling off. Furthermore, the space outside the locking groove 112 is increased, and the amount of foam material 300 outside the locking groove 112 is increased, thereby increasing the volume of the foamed locking portion 310 and improving the connection stability.

[0035] In this embodiment, the injection hole 130 is provided at the bottom of the base 100, and passes through the base 100 and communicates with the inner cavity 120 of the support portion 110. In other embodiments, the injection hole 130 can also be provided at other positions of the base 100.

[0036] Furthermore, the bottom of the outer cylinder module also has a motor 500. The base 100 has two support portions 110. These two support portions 110 are used to securely support the counterweight 400 and the motor 500, respectively. The above description and accompanying drawings of this embodiment illustrate only the example of a support portion 110 securing the counterweight 400. It should be noted that the support portion 110 securing the motor 500 can also employ the same structure as the support portion 110 securing the counterweight 400, and similarly be encased in the flexible housing 200, though this is not shown in the accompanying drawings of this embodiment.

[0037] The present invention also provides a method for manufacturing a packaging structure, see Figure 2-Figure 9 The packaging structure includes a base 100 and a flexible shell 200 arranged on the base 100.

[0038] The base 100 has at least one supporting portion 110 . The supporting portion 110 has an inner cavity 120 with an open top surface. The base 100 is provided with an injection hole 130 communicating with the inner cavity 120 .

[0039] The flexible shell 200 is made of a flexible material, such as rubber, silicone, or elastic plastic. It has an internal cavity 210. The flexible shell 200 is positioned over the top opening of the support portion 110 via an injection port, connecting the internal cavity 210 of the flexible shell 200 with the inner cavity 120 to form an injection cavity. The injection cavity is filled with a foam material 300.

[0040] The manufacturing method of the packaging structure specifically includes: S100 , the base 100 is formed by foaming.

[0041] S200 , the flexible shell 200 is placed on the support portion 110 of the base 100 .

[0042] S300 , placing the outer cylinder module on the packaging structure, and the flexible shell 200 is deformed due to the compression of the bottom of the outer cylinder module.

[0043] S400 , injecting the foaming material 300 from the injection hole 130 of the base frame 100 , and utilizing the foaming ability of the foaming material 300 to tightly combine the flexible shell 200 with the bottom of the outer cylinder module.

[0044] Among them, the foaming injection process can be allocated at the machine placement position without providing additional production nodes.

[0045] The base 100 is formed by foaming polystyrene, and the foaming material 300 is injected from the injection hole 130 of the base 100 and is formed by foaming polyurethane.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
