[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0037] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0038] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] The first aspect of the present application proposes a packaging structure, which can be wrapped around the outside of the packaged object to form a protective layer. For example, some household appliances such as refrigerators and dishwashers are often packaged with packaging structures before transportation. Taking the dishwasher as an example, during the transportation of the packaged dishwasher, it is inevitable that it may fall or collide. In order to cushion and absorb the impact force to reduce damage to the dishwasher, in the related art, EPS (Expanded Polystyrene, polystyrene plastic) foam is set on the bottom bracket of the packaging structure to cushion the fall and impact during transportation to ensure the protection of household appliances. However, EPS foam is not easy to degrade and is easy to pollute the environment.

[0041] In order to solve the above problem, the second aspect of the present application proposes a bottom support structure 100 . In an embodiment of the present application, the bottom support structure 100 includes a paper support body 10 and an energy absorbing member 20 .

[0042] For ease of expression, the definition is as follows Figure 1 In the front-to-back direction, the up-down direction, and the left-to-right direction shown, the dishwasher is placed above the paper support body 10, and the paper support body 10 plays a role in protecting and supporting the bottom of the dishwasher. The shape of the paper support body 10 can be adapted to the shape and size of the bottom of the packaged dishwasher. In one embodiment of the present application, the outer contour of the paper support body 10 can be set in a rectangular block shape, and the bottom of the dishwasher can be placed inside.

[0043] The energy absorbing member 20 is used to protect the side wall of the bottom of the dishwasher, so as to absorb and disperse the impact energy when the packaging structure containing the dishwasher falls or is hit. The energy absorbing member 20 can only abut against one side wall of the bottom of the dishwasher for protection, or the energy absorbing member 20 can simultaneously abut against the circumferential side wall of the bottom of the dishwasher for protection. It can be understood that the paper holder body 10 and the energy absorbing member 20 are both made of paper structure, which effectively avoids the overall weight being too heavy and meets environmental protection requirements.

[0044] Reference Figures 1 to 3 The energy absorbing member 20 includes a flexible portion 21 and a hard portion 22. It is understandable that the structural strength of the hard portion 22 is greater than the structural strength of the flexible portion 21. Specifically, the flexible portion 21 and the hard portion 22 can have different strengths by using different materials, or they can have different strengths by combining different structural shapes. The hard portion 22 and the flexible portion 21 can be fixed as one by bonding or the like. This integrated design not only simplifies the installation process, so that the two can be installed simultaneously during installation, thereby improving work efficiency, but also ensures a close connection between the two, ensuring that the energy absorbing member 20 can work together when impacted to achieve the best energy absorption effect.

[0045] However, in some specific applications, it may be more appropriate to design the hard part 22 and the flexible part 21 as a split structure. The split structure design allows the two to remain relatively independent during manufacturing, transportation and installation, thereby facilitating operation and management. In addition, the split structure also provides greater flexibility, and the hard part 22 and the flexible part 21 can be replaced or repaired separately according to actual needs, reducing maintenance costs.

[0046] Based on the embodiment of the present application, the bottom support structure 100 of the packaging structure is composed of a paper support body 10 and an energy absorbing member 20 of a paper structure. Compared with the existing solution of using EPS foam material for buffering, the selection of this paper material is more environmentally friendly in the production, use and waste treatment process, which helps to reduce pollution to the environment, and has good mechanical properties and wear resistance, and can provide stable support for the packaged objects during transportation and storage. At the same time, the energy absorbing member 20 includes a flexible portion 21 and a hard portion 22. The flexible portion 21 abuts against the packaged object. In this way, when subjected to external force, the flexibility and resilience of the flexible portion 21 can effectively buffer the impact force transmitted to the packaged object, and reduce the hard contact with the packaged object, thereby reducing the risk of damage. The hard portion 22 is firmly arranged on the paper support body 10, so that when the packaging structure falls or is hit, the hard portion 22 can not only play a supporting role, ensuring the integrity and stability of the bottom support structure 100, but also enable the flexible portion 21 to better play its buffering role, providing more reliable protection for the packaged object.

[0047] In this way, through the design of the bottom support structure 100 of the present application, the packaged objects can be effectively protected during transportation and storage, reducing the damage caused by falling or impact, while also reducing pollution to the environment, which is more environmentally friendly.

[0048] Reference Figures 1 to 3 In some structural forms, the first direction is defined from the center of the paper holder body 10 to the edge of the paper holder body 10. The flexible portion 21 and the hard portion 22 are stacked in sequence along the first direction. That is, the flexible portion 21 and the hard portion 22 are arranged in sequence in the horizontal direction, and the hard portion 22 is located outside the flexible portion 21, so that the hard portion 22 can bear the main load and provide solid support, while the flexible portion 21 is distributed to play a role of buffering and shock absorption, effectively dispersing the impact force, so that when the packaging structure falls or is hit, the above arrangement can further reduce the external force in the horizontal direction, thereby protecting the packaged objects from damage.

[0049] Furthermore, the thickness values ​​of the flexible part 21 and the hard part 22 in the first direction are D1 and D2 respectively, satisfying: 10mm≤D1≤200m, 10mm≤D2≤200m. Among them, when D1 and D2 are less than 10mm, the too thin flexible part 21 and the hard part 22 may not provide sufficient support and cushioning effect, and when D1 and D2 are greater than 200mm, the flexible part 21 and the hard part 22 will increase the size and weight of the bottom support structure 100, which is not conducive to transportation and storage. Therefore, the thickness value D1 of the flexible part 21 in the first direction is limited to the range of 10mm to 200mm, which can maintain sufficient softness and elasticity, effectively absorb and disperse external impact, and provide necessary cushioning protection for the packaged components. At the same time, the thickness value D2 of the hard part 22 in the first direction is in the range of 10mm to 200mm, and it can also maintain sufficient hardness and stability within this thickness range, providing solid support for the paper tray to prevent it from deformation or damage. Specifically, D1 and D2 are limited to between 10 mm and 200 mm, for example, 10 mm, 50 mm, 100 mm, 150 mm and 200 mm.

[0050] Optionally, the thickness values ​​of the flexible part 21 and the hard part 22 in the up and down directions of the paper holder body 10 are H1 and H2, respectively, satisfying: 10mm≤H1≤200m, 10mm≤H2≤200m. Among them, when H1 and H2 are less than 10mm, the too thin flexible part 21 and the hard part 22 may not provide sufficient support and cushioning effect, and when H1 and H2 are greater than 200mm, the flexible part 21 and the hard part 22 will increase the size and weight of the bottom support structure 100, which is not conducive to transportation and storage. Thus, the thickness value H1 of the flexible part 21 in the first direction is limited to the range of 10mm to 200mm, which can maintain sufficient softness and elasticity, effectively absorb and disperse external impact, and provide necessary cushioning protection for the packaged components. At the same time, the thickness value H2 of the hard part 22 in the first direction is in the range of 10mm to 200mm, and it can also maintain sufficient hardness and stability within this thickness range, providing solid support for the paper holder to prevent it from deformation or damage. Specifically, H1 and H2 are limited to between 10 mm and 200 mm, for example, 10 mm, 50 mm, 100 mm, 150 mm and 200 mm.

[0051] Another arrangement of the flexible portion 21 and the hard portion 22 can be: along the up and down direction of the paper holder body 10, the flexible portion 21 and the hard portion 22 are stacked in sequence from top to bottom. In this way, the hard portion 22 is placed at the bottom, firstly ensuring the vertical stability of the support. The hard portion 22 serves as the core of the support, and its solid texture provides a solid foundation for the entire piece, effectively preventing the displacement or shaking of the support during use. In addition, when the packaging structure falls or is hit, the above arrangement can further reduce the external force in the vertical direction, thereby further protecting the packaged objects from damage.

[0052] Another arrangement of the flexible portion 21 and the hard portion 22 may be: the first direction is defined as pointing from the center of the paper holder body 10 to the edge of the paper holder body 10, and the second direction is the up-down direction of the paper holder body 10. The hard portion 22 includes a first sub-portion and a second sub-portion that are connected to each other, the flexible portion 21 and the first sub-portion are stacked in sequence along the first direction, and the flexible portion 21 and the second sub-portion are stacked in sequence along the second direction. Among them, the first sub-portion and the second sub-portion may be an integral structure to ensure the structural strength of the hard portion 22. By setting the first sub-portion, the hard portion 22 can support the flexible portion 21 in the horizontal direction to improve the impact resistance in the horizontal direction, and by setting the second sub-portion, the hard portion 22 can support the flexible portion 21 in the vertical direction to improve the impact resistance in the vertical direction. The above arrangement can further reduce the external force in the vertical and horizontal directions at the same time, so as to further protect the packaged objects from damage.

[0053] In addition, the first sub-section and the second sub-section can be cleverly matched to form an L-shaped structure. This shape design not only increases the structural stability of the hard portion 22, but also provides a perfect accommodation space for the flexible portion 21. The flexible portion 21 can be easily placed in the notch of the L-shaped structure, and its stability and position accuracy on the paper holder body 10 can be ensured without additional fixing measures.

[0054] In some structural forms, the hard part 22 includes a single layer or multiple layers of corrugated paperboard or a composite corrugated paperboard, and the extension direction of the corrugation points to the edge of the paper support body 10 along the center of the paper support body 10. Among them, the corrugated paperboard has good mechanical strength and support, can withstand a certain pressure from a plane, is elastic, and has a good buffering effect. The composite corrugated paperboard is a paperboard made by compounding different types of paperboards or materials. This composite process can involve a variety of different types of paperboards, such as kraft paper, white paperboard, etc., and combine them together through a specific process to form a paperboard with a multi-layer structure. On this basis, the corrugated paperboard and the composite corrugated paperboard also have the advantage of being recyclable. At the same time, by making the extension direction of the corrugation along the center of the paper support body 10 pointing to the edge of the paper support body 10, the hard part 22 is more stable in the extension direction and is not easy to deform, so that the external force in the horizontal direction can be further reduced, thereby protecting the packaged objects from damage.

[0055] Optionally, the flexible part 21 comprises a single-layer or multi-layer honeycomb paperboard. Generally, the honeycomb paperboard is made of a flexible paper core and a surface paper, has good toughness and resilience, and the honeycomb structure provides excellent buffering performance, so that the flexible part 21 can be stable and effectively protect the dishwasher.

[0056] Reference Figures 1 to 3, the following still takes the dishwasher as an example for explanation. The paper tray body 10 can be made entirely of corrugated paper, or it can be composed of a combination of corrugated paper and other paper structures. In some embodiments, the paper tray body 10 includes a bottom plate 11 and a surrounding plate 12 arranged around the bottom plate 11, and at least part of the surrounding plate 12 protrudes from the upper surface of the bottom plate 11. In this way, the bottom plate 11 and the surrounding plate 12 cooperate to form a receiving groove 10A. The existence of this receiving groove 10A provides a precise positioning space for the flexible part 21 and the hard part 22, ensuring the stability and convenience of installation. At the same time, the surrounding plate 12 includes a front side plate 121, a left side plate 122, a rear side plate 123 and a right side plate 124 connected in sequence, and the front side plate 121 and the rear side plate 123 are arranged relative to each other, and the left side plate 122 and the right side plate 124 are arranged relative to each other. This not only enhances the overall structural stability of the paper tray body 10, but also provides all-round protection for the dishwasher. The flexible portion 21 and the hard portion 22 are both arranged on the upper surface of the bottom plate 11, and the hard portion 22 is at least partially arranged corresponding to the front side plate 121, and the hard portion 22 is located between the flexible portion 21 and the front side plate 121. Such a layout enables the front side plate 121 to first withstand external force when the dishwasher is dropped or hit, and then transfer the external force to the flexible portion 21 through the hard portion 22, thereby playing a role of buffering and protection. It is understandable that in other designs, the hard portion 22 can be further extended to form a close corresponding relationship with the left side plate 122, the right side plate 124 and the rear side plate 123. Such a design enables the hard portion 22 to not only support and protect the front side plate 121, but also provide additional support and protection for the left side, right side and rear side of the dishwasher, thereby further enhancing the overall protection capability of the bottom of the dishwasher.

[0057] Reference Figures 1 to 3 In an optional structural form, the enclosure 12 is not only composed of a front side panel 121, a left side panel 122, a rear side panel 123 and a right side panel 124, but also includes a retaining edge 125 arranged at the bottom of the above-mentioned side panels, and the retaining edge 125 is tightly matched with the front side panel 121, the left side panel 122, the rear side panel 123 and the right side panel 124 to form an assembly groove 12A. The retaining edge 125 not only serves as an auxiliary tool during installation, but also provides additional support for the bottom plate 11 to ensure that the relative position between the bottom plate 11 and the enclosure 12 is stable and unchanged. This structural mutual support effectively improves the stability and durability of the entire paper tray. Furthermore, the retaining edge 125 and the bottom plate 11 can be bonded and fixed to achieve a tighter connection. This bonding and fixing method not only enhances the overall strength of the paper tray body 10, but also further improves the stability after installation, ensuring that the dishwasher can be fully protected during transportation.

[0058] Furthermore, the flexible portion 21 and the hard portion 22 are both arranged in a strip-shaped structure, which is not only convenient for processing and installation, but also can effectively increase the contact area with the enclosure 12. The two opposite ends of the flexible portion 21 along the length direction are respectively abutted against the left plate 122 and the right plate 124, and the two ends of the flexible portion 21 along the length direction are limited to improve the stability of the flexible portion 21 after installation. The hard portion 22 can also follow the same design principle, and its two ends in the length direction are also tightly fitted with the left plate 122 and the right plate 124, and the two ends of the hard portion 22 along the length direction are also limited to improve the stability of the hard portion 22 after installation. Of course, the two opposite ends of the flexible portion 21 and the hard portion 22 along the length direction can also be abutted against the left plate 122 and the right plate 124 at the same time. Such a design not only combines the above two advantages, but also further improves the stability and durability of the support through the synergistic effect of the flexible portion 21 and the hard portion 22. This design provides solid protection for the dishwasher whether facing slight vibrations or strong impacts.

[0059] Reference Figures 1 to 3 Optionally, the surface of the flexible portion 21 facing away from the bottom plate 11 is flush with the surface of the hard portion 22 facing away from the bottom plate 11. This design structurally enhances the stability of the support. The flexible portion 21 and the hard portion 22 are flush on the surface facing away from the bottom plate 11, which means that a tighter combination is formed between them, effectively avoiding loosening or displacement that may occur during use. It should be noted that the surface of the flexible portion 21 facing away from the bottom plate 11 and the surface of the hard portion 22 facing away from the bottom plate 11 can also be flush with the upper surface of the front side plate 121 of the enclosure 12, so that the flexible portion 21 and the hard portion 22 can be fully supported by the front side plate 121. Of course, in order to improve the protection effect, the surface of the flexible portion 21 facing away from the bottom plate 11 and the surface of the hard portion 22 facing away from the bottom plate 11 can also be higher than the upper surface of the front side plate 121 of the enclosure 12. Alternatively, in order to reduce costs, the surface of the flexible portion 21 away from the bottom plate 11 and the surface of the hard portion 22 away from the bottom plate 11 can also be lower than the upper surface of the front side plate 121 of the enclosure 12. The specific selection can be made by technical personnel in this field according to needs.

[0060] In some embodiments, the bottom plate 11 includes a honeycomb paperboard and a composite corrugated paperboard arranged in sequence in a direction away from the flexible portion 21. First, the honeycomb paperboard exhibits excellent compressive strength and stability due to its unique honeycomb structure. This structure can buffer and absorb energy when falling or impacting. At the same time, the composite corrugated paperboard as the second layer of the bottom plate 11 further enhances the impact resistance of the bottom plate 11. Its unique corrugated structure makes the bottom plate 11 not easy to deform, ensuring its structural stability. In general, the bottom plate 11 adopts a combination design of honeycomb paperboard and composite corrugated paperboard, which not only improves the buffering and energy absorption of the bottom plate 11, but also significantly improves its impact resistance and structural stability.

[0061] Reference Figures 1 to 3 Optionally, the bottom support structure 100 also includes a buffer lining 30, which is at least arranged between the front side plate 121 and the hard part 22, and the buffer lining 30 includes a honeycomb paperboard to buffer the impact force transmitted to the hard part 22 through the front side plate 121. It can be understood that the buffer lining 30 can play a role in reducing the impact force. In this embodiment, the buffer lining 30 can be arranged on the surface of the front side plate 121 facing the hard part 22 by gluing or other methods, so as to form a multi-layer structure of the front side plate 121-buffer lining 30-hard part 22-flexible part 21, which can further improve the ability of the bottom support structure 100 to resist impact force and improve protection. It should be noted that the buffer lining 30 can be an annular structure, so as to extend and connect with the left side plate 122, the right side plate 124, and the rear side plate 123 at the same time, so as to further improve the ability of the bottom support structure 100 to resist impact force.

[0062] Generally speaking, there is often a certain bottom gap between the housing and the skirting board of the dishwasher. In this regard, optionally, the bottom support structure 100 also includes a limiter 40 disposed on the bottom plate 11, and the limiter 40 is spaced apart from the flexible portion 21. The limiter 40 is used to pass through the above bottom gap and abut the bottom of the dishwasher housing. Optionally, the limiter 40 includes a plurality of corrugated cardboards stacked along the thickness direction of the bottom plate 11. When the dishwasher is set on the bottom support structure 100, the limiter 40 can support the bottom of the dishwasher housing and the skirting board, thereby improving the stability of the dishwasher.

[0063] Among them, when the dishwasher is placed on the paper support body 10, most of the weight of the dishwasher is borne by the bottom plate 11. When the bottom plate 11 is impacted, the deformation of the bottom plate 11 is large, and the impact force to be resisted is also strong. Therefore, in one embodiment, optionally, the bottom support structure 100 also includes a buffer pad 50, and the buffer pad 50 is arranged on the upper surface of the bottom plate 11, so that when the dishwasher is arranged on the bottom support structure 100, the dishwasher is placed on the buffer pad 50 to buffer the bottom surface of the dishwasher. Optionally, the buffer pad 50 includes honeycomb paperboard. Commonly, honeycomb paperboard is made of a flexible paper core and a facial paper, has good toughness and resilience, and the honeycomb structure provides excellent buffering performance. In addition, the front and rear dimensions of the buffer pad 50 are smaller than the front and rear dimensions of the bottom plate 11, so that two sinks 60 are formed on the front and rear sides of the buffer pad 5033. When there are two support members, they can be respectively arranged in the two sinks 60 to avoid displacement of the two support members.

[0064] The above is an explanation of the specific structural example of the bottom support structure 100 of the embodiment of the present application.
