[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] The packaging structure can be wrapped around the outside of the packaged object to form a protective layer to protect the packaged object during transportation. Commonly, some household appliances such as refrigerators and dishwashers are often packaged with packaging structures before transportation. Taking dishwashers as an example, during the transportation of packaged dishwashers, it is inevitable that they may fall or hit. In order to cushion and absorb the impact force to reduce damage to the dishwasher, EPS foam is often used as a vibration-absorbing and buffering material in related technologies. However, EPS foam is easy to pollute the environment due to its difficult-to-degrade characteristics.

[0055] In view of this, the embodiment of the present application proposes a packaging structure 100. Next, the packaging structure 100 is used for packaging a dishwasher, especially a built-in dishwasher, as an example for explanation.

[0056] Please refer to Figures 1 to 3 In some embodiments of the present application, the packaging structure 100 includes a corrugated box 10 and an energy absorbing component 30 .

[0057] The corrugated box 10 plays a protective and supporting role. The shape and size of the corrugated box 10 should be adapted to the shape and size of the dishwasher being packaged. Figure 1 In the illustrated embodiment, the corrugated box 10 is substantially in the shape of a rectangular parallelepiped, and a dishwasher can be placed therein.

[0058] For the convenience of description, the front-back direction, the up-down direction and the left-right direction are defined as shown in the figure. The corrugated box body 10 includes a cylinder 13 and an upper cover 11 and a lower cover 15 connected to the upper and lower ends of the cylinder 13. The cylinder 13 is a quadrangular prism with a hollow interior and openings on both sides. The upper cover 11 is arranged above the cylinder 13 and is used to cover the upper opening of the cylinder 13. The lower cover 15 is arranged opposite to the upper cover 11, is located below the cylinder 13, and is used to cover the lower opening of the cylinder 13. The connection method of the upper cover 11, the lower cover 15 and the cylinder 13 is not limited in this application. The upper cover 11 and the cylinder 13 can be connected by sleeve connection, bonding, etc., and the connection method of the lower cover 15 and the cylinder 13 can be the same or different from that of the upper cover 11. The matching method of the upper cover 11, the lower cover 15 and the cylinder 13 is more convenient for the packaging structure 100 to be assembled outside the dishwasher, and the assembly efficiency is high. After the upper cover 11 and the lower cover 15 are connected to the drum 13, the upper cover 11, the lower cover 15 and the drum 13 together enclose a mounting cavity 10a for placing the dishwasher.

[0059] The corrugated box body 10 is made of a paper structure. Specifically, the cylinder 13 and at least most of the upper cover 11 and the lower cover 15 can be made of corrugated cardboard. The corrugated cardboard has good mechanical strength and support, can withstand a certain pressure from a plane, is elastic, and has a good buffering effect. On this basis, the corrugated cardboard also has the advantage of being recyclable.

[0060] Reference Figure 2 and Figure 3 The energy absorbing component 30 is arranged in the corrugated box 10, and plays a role of buffering and resisting impact, so as to protect the dishwasher when the packaging structure 100 containing the dishwasher falls or is hit. The energy absorbing component 30 includes at least two stoppers 35, wherein the two stoppers 35 are arranged on the lower cover 15 and are arranged opposite to each other to respectively abut against the bottom of the dishwasher, and the two stoppers 35 respectively abut against the opposite two side walls of the bottom of the dishwasher, that is, the front side and the rear side, to achieve a limiting effect on the dishwasher. Furthermore, the number of the stoppers 35 can be set to multiple, and they are arranged along the peripheral side of the dishwasher to abut against multiple peripheral wall surfaces of the dishwasher, which not only improves the limiting effect, but also improves the buffering effect.

[0061] Based on the embodiments of the present application, on the basis of providing high mechanical strength and good wear resistance and impact resistance of the corrugated paper box, an energy absorbing component 30 having at least two baffles 35 is provided. The two baffles 35 are provided on the lower cover 15 to abut against the opposite sides of the packaged object (dishwasher). In this way, when the packaging structure 100 of the packaged object falls or is hit during transportation, not only can the corrugated box body 10 withstand the impact force generated by the fall or impact, but the impact force transmitted to the packaged object is further reduced by the two baffles 35, thereby effectively protecting the packaged object and reducing the risk of failure of the packaged object during transportation.

[0062] Combined with reference Figure 4 and Figure 5 Furthermore, each stopper 35 includes a first plate 351 and a second plate 353 that are cross-connected, which not only provides good support, but also uses less material, which is conducive to reducing costs. When subjected to impact force, the first plate 351 and the second plate 353 can also produce relative displacement and twist to further improve the buffering and energy absorption effect, and further reduce the impact on the packaged object. At the same time, on this basis, the corrugated box 10 and the first plate 351 and the second plate 353 are all made of degradable and recyclable corrugated paperboard. Therefore, the present application not only achieves good protection and reliability of the packaging structure 100, but also reduces pollution to the environment, which is more environmentally friendly.

[0063] When the dishwasher is packaged in the packaging structure 100, the first plate 351 has a first limiting surface 3511 and a second limiting surface 3513 that are arranged opposite to each other. The first limiting surface 3511 is used to abut the inner wall surface of the cylinder 13, and the second limiting surface 3513 is used to abut the packaged object. It can be understood that in this embodiment, the first plate 351 mainly plays a role of abutment to stably maintain the distance between the cylinder 13 and the dishwasher, thereby improving the support and buffering performance of the dishwasher. At the same time, in the projection direction of the upper cover 11 toward the lower cover 15, the second plate 353 is arranged vertically with the first plate 351. That is, the first plate 351 and the second plate 353 are arranged in a "cross" shape, and the cross intersection surface abuts the upper surface of the lower cover 15 to improve the stability of the stopper 35 at the lower cover 15. The cross-shaped structure can evenly disperse the force received, so that the stopper 35 is not easy to produce excessive stress concentration when it is subjected to external impact or extrusion, thereby improving the stability of the stopper 35. In another arrangement, the cross-intersecting surfaces of the first plate 351 and the second plate 353 can be arranged to face the bottom of the dishwasher and the side wall of the drum 13, and then the first plate 351 or the second plate 353 can be abutted against the upper surface of the lower cover 15. In this way, the contact area between the stopper 35 and the side wall of the drum 13 and the dishwasher is increased, so as to improve the effect of stably maintaining the distance between the drum 13 and the dishwasher, thereby improving the support and buffering performance of the dishwasher.

[0064] Furthermore, in this embodiment, in order to improve the fit between the stopper 35 and the bottom of the dishwasher, the shape of the limiting surface of the first plate 351 is roughly similar to the shape of the bottom of the dishwasher. For example, the bottom of the side wall of the dishwasher is often provided with an arc-shaped skirting board, and correspondingly, the limiting surface of the first plate 351 is set in an arc surface, which can better fit the skirting board at the bottom of the dishwasher, increase the contact area, and improve the stability of the dishwasher.

[0065] Reference Figure 4 Optionally, the lower surface of the first plate 351 and the lower surface of the second plate 353 are both in contact with the top surface of the lower cover 15. That is, the cross-intersecting surfaces of the first plate 351 and the second plate 353 are in contact with the top surface of the lower cover 15 to increase the contact area between the stopper 35 and the lower cover 15, thereby further improving the stability of the stopper 35 located on the lower cover 15.

[0066] In some structural forms, reference Figure 5, there are multiple first plates 351, and the multiple first plates 351 are arranged at intervals along the length extension direction of the second plate 353. Through the multiple first plates 351 arranged at intervals, the contact area between the stopper 35 and the inner wall of the cylinder 13 and the dishwasher can be increased to further stably maintain the spacing between the cylinder 13 and the dishwasher. The first plates 351 arranged at intervals can more effectively absorb and disperse the impact force, reducing the possibility of the impact force being transmitted to the dishwasher, thereby improving the buffering effect and protection performance of the entire packaging structure 100. In addition, a wiring structure is often suspended on the rear side of the bottom of a dishwasher or other household appliances, and the wiring structure is used to connect a power supply. In order to avoid squeezing the wiring structure, the space between the first plates 351 arranged at intervals can also be used to accommodate the wiring structure to form a package for the wiring structure, effectively reducing the impact of the impact force on the wiring structure. Of course, the above-mentioned structural design of the stopper 35 of the embodiment of the present application is not only applicable to the wiring structure, but also to other structures protruding or suspended at the bottom of other household appliances, which will not be repeated here.

[0067] Further, the spacing between adjacent first plates 351 at the end of the second plate 353 is smaller than the spacing between adjacent first plates 351 at the middle of the second plate 353. It is understandable that in the design of the packaging structure 100, the end is often a region with greater force, because the impact force is often concentrated here. Smaller spacing means that the multiple first plates 351 at the end of the second plate 353 are more densely connected, which can increase the strength and stability of the end of the stopper 35 and reduce deformation and damage when impacted. By reducing the spacing between adjacent first plates 351 at the end of the second plate 353, the support points at the end of the stopper 35 can be increased, making the stopper 35 more stable and able to more effectively resist impact force, thereby improving the support and buffering performance of the dishwasher.

[0068] In another configuration, the spacing between adjacent first plates 351 is equal. Keeping the spacing between adjacent first plates 351 equal can simplify the manufacturing process and make the assembly process easier and more efficient. By unifying the spacing, the complexity in manufacturing and the adjustment in assembly can be reduced, thereby reducing production costs and improving production efficiency.

[0069] Optionally, refer to Figure 5 There are multiple second plates 353, and the multiple second plates 353 are arranged at intervals along the length extension direction of the first plate 351. The multiple second plates 353 arranged at intervals increase the support points with the first plate 351, so that the stopper 35 is more firmly fixed on the corrugated box 10, reducing the possibility of deformation and displacement of the stopper 35 when impacted, and improving the buffering effect and protection performance of the entire packaging structure 100.

[0070] Furthermore, the spacing between adjacent second plates 353 at the ends of the first plates 351 is smaller than the spacing between adjacent second plates 353 at the middle of the first plates 351. Similar to the arrangement of the plurality of first plates 351, the strength and stability of the ends of the stopper 35 can also be increased, and deformation and damage when impacted can be reduced. By reducing the spacing between adjacent second plates 353 at the ends of the first plates 351, the support points at the ends of the stopper 35 can be increased, making the stopper 35 more stable and more effectively able to resist impact force, thereby improving the support and buffering performance of the dishwasher.

[0071] Combined with reference Figure 2 and Figure 5 In some structural forms, a notch may be formed on the upper surface of the first plate 351, and the notch is connected to the first limiting surface 3511, so that the upper surface of the first plate 351 and the first limiting surface 3511 define a contour groove 35A. That is, in the front-to-back direction, a contour groove 35A is provided on the side of the stopper 35 away from the dishwasher, so as to accommodate special-shaped structures such as the outer contour of the dishwasher, so as to increase the contact area with the dishwasher. For example, the contour groove 35A can be used to accommodate the edge of the door body of the dishwasher, and the two side walls of the contour groove 35A abut against the bottom wall and side walls of the edge of the door body of the dishwasher to be closely combined for buffering. It can be understood that the contour groove 35A is not limited to the above-mentioned form, and can be adjusted according to the bottom shape of the dishwasher.

[0072] Optionally, in conjunction with reference Figure 2 and Figure 5 , the lower surface of the first plate 351 and the second limiting surface 3513 of at least one stopper 35 define an avoidance groove 35B, and the inner wall of the avoidance groove 35B is used to abut against a part of the surface of the packaged object. Similarly, in the front-to-back direction, an avoidance groove 35B can be set on the side of the stopper 35 close to the dishwasher to accommodate special-shaped structures such as the outer contour of the dishwasher to increase the contact area with the dishwasher. For example, the avoidance groove 35B can be used to accommodate the electric control box at the edge of the dishwasher, and the two side walls of the avoidance groove 35B abut against the bottom wall and side walls of the edge of the electric control box of the dishwasher to be tightly combined for buffering. It can be understood that the avoidance groove 35B is not limited to the above form and can be adjusted according to the bottom shape of the dishwasher.

[0073] Reference Figure 5 and Figure 6In some embodiments, the first plate 351 is provided with a first plug-in port 351a, and the second plate 353 is provided with a second plug-in port 353a, and the first plate 351 and the second plate 353 are cross-inserted and integrated into one body through the first plug-in port 351a and the second plug-in port 353a. In this way, by using the first plug-in port 351a and the second plug-in port 353a, the first plate 351 and the second plate 353 can be more firmly connected together, thereby enhancing the structural stability of the entire baffle 35. This cross-insertion combination method can effectively prevent the baffle from moving or loosening when impacted, and maintain the integrity of the packaging structure 100. The design of the plug-in port makes the assembly between the first plate 351 and the second plate 353 simpler and more efficient. Workers only need to insert the first plate 351 and the second plate 353 into the corresponding plug-in ports to complete the assembly, without the need for additional tools or complicated steps, thereby saving assembly time and cost. In summary, the design of the first plug-in port 351a and the second plug-in port 353a can improve the stability, reliability and adjustability of the packaging structure 100, thereby better protecting the packaged objects and meeting different packaging requirements.

[0074] Reference Figure 2 and Figure 3 In some embodiments, the energy absorbing assembly 30 further includes a lower buffer pad 33 and a side buffer pad 31. The lower buffer pad 33 is disposed on the inner surface of the lower cover 15, and the side buffer pad 31 is attached to the inner surface of the cylinder 13 and is arranged along the circumference of the cylinder 13. The lower buffer pad 33 and the side buffer pad 31 both include honeycomb paperboard.

[0075] Commonly, honeycomb paperboard is made of a flexible paper core and a face paper, has good toughness and resilience, and the honeycomb structure provides excellent cushioning performance. The lower cushion pad 33 is arranged on the inner surface of the lower cover 15. When the dishwasher is arranged in the installation cavity 10a, the dishwasher is placed on the lower cushion pad 33. The side cushion pad 31 is arranged on the inner surface of the cylinder 13 and is arranged along the circumference of the cylinder 13. That is, in order to protect the peripheral side of the dishwasher, the side cushion pad 31 on the inner surface of the cylinder 13 can also be roughly cylindrical. Among them, the side cushion pad 31 can be an integrated cylindrical structure, or it can be spliced ​​by a plurality of pads arranged along the circumference of the cylinder 13, and the embodiment of the present application does not limit this. Specifically, the lower cushion pad 33 and the side cushion pad 31 can be directly attached to the inner surface of the lower cover 15 and the inner surface of the cylinder 13 respectively, or in order to improve the connection strength, the lower cushion pad 33 and the side cushion pad 31 can also be arranged on the inner surface of the lower cover 15 and the inner surface of the cylinder 13 by gluing.

[0076] Combined with reference Figure 7 and Figure 8Further, the packaging structure 100 includes a support assembly 70, which is arranged in the corrugated box 10 and is used to provide lateral support for the cylinder 13 at least. It can be understood that the support assembly 70 can be made of a material that is harder than paper and has a more stable structure, so that it can play a supporting role and play a compressive role when subjected to external pressure. For example, the support assembly 70 can be made of degradable hard plastic, wood, etc., and can adopt a strip-shaped, plate-shaped, etc. structure. During transportation, the packaging structure 100 may be deformed due to shaking, collision, or due to the clamping effect during transportation. The support assembly 70 can be directly connected to the cylinder 13. When the cylinder 13 has a tendency to deform under external action, for example, the opposite sides of the cylinder 13 have a tendency to approach each other, the support assembly 70 can provide support for the cylinder 13 to avoid excessive deformation of the cylinder 13 and cause the overall structure of the packaging structure 100 to fail, thereby ensuring structural reliability. Alternatively, the support assembly 70 may also be connected to the side buffer pads 31. When the cylinder 13 is deformed, the cylinder 13 acts on the internal side buffer pads 31 and causes the side buffer pads 31 to deform. Therefore, the support structure may indirectly act on the cylinder 13 by supporting the side buffer pads 31 to provide support for the cylinder 13. Of course, the support assembly 70 may also be connected to both the cylinder 13 and the side buffer pads 31, which can further improve the tightness of the structure and provide support for the overall structure of the corrugated box 10 and the energy absorbing assembly 30. Furthermore, by connecting the support assembly 70 to multiple-side structures of the cylinder 13 and the side buffer pads 31, the support assembly 70 can support the deformation of multiple sides of the cylinder 13.

[0077] When the dishwasher is packaged in the packaging structure 100, the support assembly 70 can be arranged on the peripheral side of the dishwasher. For example, the support assembly 70 can be arranged in a frame shape and enclose a through hole for the dishwasher to pass through. In some other embodiments, the support assembly 70 is arranged close to the upper cover 11 and is located on the top of the dishwasher. On the one hand, in this case, the support assembly 70 has a better supporting effect; on the other hand, in this way, after the dishwasher is placed in the cylinder 13, the support assembly 70 is placed on the top of the dishwasher, and the support assembly 70 is connected to at least one of the cylinder 13 or the side buffer plate, and finally the upper cover 11 is connected to the cylinder 13 to complete the assembly. The assembly is relatively convenient and efficient.

[0078] Reference Figure 8In some embodiments, the support assembly 70 includes at least two support members 71. In the embodiment shown in the figure, the support assembly 70 includes three support members 71, each support member 71 is in the shape of a long strip and extends along the left-right direction, and the three support members 71 are arranged side by side at intervals along the front-back direction. Among them, the two ends of each support member 71 are connected to the opposite side walls of the cylinder 13. When the cylinder 13 is deformed, the end of the support member 71 can provide support for the cylinder 13. Multiple support members 71 can achieve multi-point support on the side wall of the cylinder 13, making the structure more stable. In addition, compared with the solution in which the support members 71 are completely covered, since the intervals between two adjacent support members 71 are set, while providing effective support, the weight of the support assembly 70 can be reduced, and the support assembly 70 can be prevented from damaging the corrugated box 10, thereby improving stability, reducing materials, and reducing costs.

[0079] Optionally, without affecting the structural strength, a hollow structure may be provided on the support member 71 to further reduce weight and save material costs.

[0080] The above-mentioned embodiment is applicable to the case where the packaging structure 100 is clamped from the left and right sides when the packaging structure 100 is transferred. The support assembly 70 can better resist the clamping force along the left and right directions to prevent the packaging structure 100 from damaging or damaging the dishwasher. For the case where the packaging structure 100 is clamped from the front and back sides, multiple support members 71 can also be arranged along the left and right directions, and each support member 71 extends along the front and back directions. Of course, the embodiment of the present application does not limit the number of support members 71, nor does it limit the structure of multiple support members 71. Multiple support members 71 can also be arranged in other feasible structures, which will not be repeated here.

[0081] Reference Figure 8 In some embodiments, to facilitate connection and assembly, the support assembly 70 further includes a connecting plate 72. The connecting plate 72 connects at least one of the cylinder 13 and the side buffer pad 31, and the support member 71 is connected to the top of the connecting plate 72 and abuts against at least two opposite side walls of the cylinder 13. The connecting plate 72 is a corrugated cardboard, which has good mechanical strength and support, and can cooperate with the support member 71 to improve the support strength. The use of corrugated cardboard can also be recycled, which is more environmentally friendly.

[0082] Furthermore, the support member 71 is made of wood. The support member 71 can be obtained by simply processing the wood, and the wood can also be recycled without polluting the environment, further making the packaging structure 100 of the embodiment of the present application more environmentally friendly.

[0083] The following explanation is still based on the dishwasher as an example. Figure 4 , Fig. 9 as well as Fig.10, the lower cover 15 can be made entirely of corrugated paper, or it can be composed of corrugated paper and other paper structures. In one embodiment, the lower cover 15 includes a lower cover plate 151 and a lower retaining edge 153. The lower cover plate 151 covers an opening of the cylinder 13, so that the shape and size of the lower cover plate 151 are roughly the same as the shape and size of the opening of the cylinder 13. The lower retaining edge 153 is arranged along the circumference of the lower cover plate 151, and the lower retaining edge 153 extends toward the side of the lower cover plate 151 facing the cylinder 13, and forms a lower mounting groove 15a with the lower cover plate 151. Among them, the lower cover plate 151 is made of corrugated paperboard. In order to further improve the strength and support, the lower cover plate 151 can also adopt a composite corrugated paperboard with a multi-layer corrugated structure. The lower retaining edge 153 can adopt a multi-layer paper structure. Among them, the lower retaining edge 153 can be a square frame formed by combining multiple edges, and one side of the lower retaining edge 153 is bonded to the upper surface of the lower cover plate 151. Alternatively, in another optional structural form, the lower rib 153 is formed into a frame structure as shown in the figure, that is, the lower rib 153 includes a bottom frame 1531 and a lower side frame 1533 connected to the bottom frame 1531 and extending upward from the bottom frame 1531, the bottom frame 1531 and the lower side frame 1533 form a lower assembly groove 153a, the lower cover 151 is arranged in the lower assembly groove 153a, and the bottom surface of the lower cover 151 is glued and connected to the bottom wall of the lower assembly groove 153a. In addition, the bottom frame 1531 of the lower rib 153 is enclosed to form an opening, so that the lower cover 151 is exposed at the opening, so that the packaging structure 100 can realize the support and protection of the bottom of the dishwasher. In this way, in the embodiment shown in the figure, the contact area between the lower rib 153 and the lower cover 15 body is larger and the connection is tighter, which is convenient for production and assembly connection, and the lower rib 153 can also protect the corners of the lower cover 15 body and improve the structural strength of the lower cover 15.

[0084] When assembling the packaging structure 100, the cylinder 13 can extend into the lower mounting groove 15a formed by the lower retaining edge 153 and the lower cover plate 151, so that the lower retaining edge 153 is arranged on the outer side of the end of the cylinder 13 close to the lower cover 15. In other words, the lower cover 15 of the embodiment of the present application is sleeved on one end of the cylinder 13, and it can be understood that the lower retaining edge 153 and the end of the cylinder 13 can form a multi-layer protection structure to improve the impact resistance of the cylinder 13.

[0085] The lower buffer pad 33 is arranged on the inner surface of the lower cover plate 151. When the dishwasher is located in the installation cavity 10a, the weight of the dishwasher is mostly borne by the lower buffer pad 33. When the dishwasher is impacted, the deformation of the lower buffer pad 33 is large, and the impact force to be resisted is also strong. Therefore, in one embodiment, the lower buffer pad 33 includes a plurality of stacked honeycomb paperboards, which are stacked in the up and down directions to ensure the effectiveness of the lower buffer pad 33 and effectively reduce the impact force to protect the dishwasher. The lower buffer pad 33 includes at least two honeycomb paperboards, and the front and rear dimensions of the honeycomb paperboard on the uppermost layer are smaller than those of the honeycomb paperboard on the next layer, so as to form two sinks on the front and rear sides of the lower buffer pad 33, and the two stoppers 35 are respectively arranged in the two sinks to prevent the two stoppers 35 from shifting.

[0086] Combined with reference Figure 4 , Fig. 9 as well as Fig.10 In one embodiment, when the cylinder 13 is connected to the lower cover 15, the portion of the lower rib 153 extending upward is spaced apart from the outer side surface of the cylinder 13 to define a lower buffer groove 10c. It can be understood that the lower buffer groove 10c is arranged around the end of the cylinder 13 close to the lower cover plate 151. The energy absorption assembly 30 also includes at least one buffer liner 37, at least one buffer liner 37 is arranged in the lower buffer groove 10c, connected to the inner surface of the lower rib 153, and arranged around the cylinder 13. Among them, the buffer liner 37 includes honeycomb paperboard. It can be understood that the buffer liner 37 can play a role in reducing impact force. In this embodiment, the buffer liner 37 can be arranged in the lower buffer groove 10c by gluing or the like, so as to form a multilayer structure of the lower rib 153-buffer liner 37-cylinder 13-side buffer pad 31, which can further improve the ability of the packaging structure 100 to resist impact force and improve protection.

[0087] The buffer liner 37 is also an annular structure. The buffer liner 37 can be pre-connected with the lower rib 153 by gluing or other methods. During the assembly process of the packaging structure 100, the lower cover 15 can be directly sleeved with the end of the cylinder 13. After the sleeve is completed, the buffer liner 37 abuts against the outer side of the end of the cylinder 13 close to the lower cover 15. Optionally, the buffer liner 37 can be an integrated annular structure, or it can be spliced ​​by multiple buffer blocks, which is easier to produce and more efficient.

[0088] In one embodiment, the buffer liner 37 or buffer block includes a plurality of honeycomb paperboards, which are stacked along the radial direction of the cylinder 13. Optionally, the plurality of honeycomb paperboards can be stacked uniformly or non-uniformly. When subjected to impact, the plurality of honeycomb paperboards can deform along at least the radial direction of the cylinder 13, which can not only further improve the resistance to impact force to protect the dishwasher, but also buffer the lower ribs 153 and the cylinder 13 on both sides of the buffer liner 37 to prevent the lower ribs 153 and the cylinder 13 from directly interacting with each other and causing the packaging structure 100 to rupture. Directly using honeycomb paperboard to form the buffer liner 37 can effectively improve the protection capability while being easy to process and having high efficiency.

[0089] In another embodiment, the buffer liner 37 is further provided with a buffer covering member covering a plurality of honeycomb paperboards. The plurality of honeycomb paperboards form a block structure, and the buffer covering member covers each surface of the block structure formed by the plurality of honeycomb paperboards and is connected to the honeycomb paperboards by gluing, thereby playing the role of gathering the plurality of honeycomb paperboards, improving the integrity of the buffer liner 37, and facilitating assembly. Optionally, the buffer covering member can be made of facial paper or corrugated paper used for packaging. When corrugated paper is used, the buffer covering member can also have further impact resistance.

[0090] Optionally, in addition to arranging a plurality of honeycomb paperboards in the cushioning covering, corrugated paper or other structures may be added according to actual needs to enhance the performance of the cushioning lining 37 and improve practicality.

[0091] The lower cushion 33 includes at least two honeycomb paperboards. The front and rear dimensions of the uppermost honeycomb paperboard are smaller than those of the lower layer of honeycomb paperboard, so as to form two sinking grooves on the front and rear sides of the lower cushion 33. The two stoppers 35 are respectively arranged in the two sinking grooves to prevent the two stoppers 35 from shifting.

[0092] Combined with reference Figure 7 , Fig.11 as well as Fig.12In the embodiment of the present application, the upper cover 11 may also be made entirely of corrugated paper, or a combination of corrugated paper and other paper structures. In one embodiment, the upper cover 11 includes an upper cover plate 111 and an upper retaining edge 113. The upper cover plate 111 covers the opening of the cylinder 13 away from the lower cover 15, and the shape and size of the upper cover plate 111 are roughly the same as the shape and size of the opening of the cylinder 13. The upper retaining edge 113 is arranged along the circumference of the upper cover plate 111, and the upper retaining edge 113 extends from top to bottom and forms an upper mounting groove with the upper cover plate 111. Among them, the upper cover plate 111 is made of corrugated paperboard. In order to further improve the strength and support, the upper cover plate 111 can also adopt a composite corrugated paperboard with a multi-layer corrugated structure. The upper retaining edge 113 can adopt a multi-layer paper structure. Exemplarily, the upper retaining edge 113 can be in the shape of a square frame composed of multiple edges, and one side of the upper retaining edge 113 is bonded to the upper surface of the upper cover plate 111. Alternatively, in another optional structural form, the upper rib 113 is formed into a frame structure as shown in the figure, that is, the upper rib 113 includes a top frame 1131 and an upper side frame 1133 connected to the top frame 1131 and extending downward from the top frame 1131, the top frame 1131 and the upper side frame 1133 construct an upper assembly groove 113a, the upper cover 111 is arranged in the upper assembly groove 113a, and the top surface of the upper cover 111 is glued and connected to the top wall of the upper assembly groove 113a. In addition, the upper rib 113 top frame 1131 is enclosed to form an opening, so that the upper cover 111 is exposed at the opening, so that the packaging structure 100 can realize the support and protection of the top of the dishwasher. In this way, in the embodiment shown in the figure, the contact area between the upper rib 113 and the upper cover 11 body is larger and the connection is tighter, which is convenient for production and assembly connection, and the upper rib 113 can also protect the corners of the upper cover 11 body and improve the structural strength of the upper cover 11.

[0093] When assembling the packaging structure 100, the cylinder 13 can be extended into the upper installation groove formed by the upper rib 113 and the upper cover plate 111, so that the upper rib 113 is arranged outside the end of the cylinder 13 close to the upper cover 11. In other words, the upper cover 11 of the embodiment of the present application is sleeved on one end of the cylinder 13, and it can be understood that the upper rib 113 and the end of the cylinder 13 can form a multi-layer protection structure to improve the impact resistance of the cylinder 13.

[0094] In one embodiment, when the cylinder 13 is connected to the upper cover 11, the portion of the upper rib 113 extending upward is spaced apart from the outer side of the cylinder 13 to define an upper buffer groove 10b. It can be understood that the upper buffer groove 10b is arranged around the end of the cylinder 13 close to the upper cover plate 111. At least one buffer liner 37 is arranged in the upper buffer groove 10b, and connects the upper rib 113 and the outer side of the cylinder 13, and is arranged around the cylinder 13. In this embodiment, the buffer liner 37 can be arranged in the upper buffer groove 10b by gluing or the like, so as to form a multi-layer structure of the upper rib 113 - buffer liner 37 - cylinder 13 - side buffer pad 31, which can further improve the ability of the packaging structure 100 to resist impact force and improve the protection.

[0095] The buffer liner 37 is also an annular structure. The buffer liner 37 can be pre-connected with the upper rib 113 by gluing or other methods. During the assembly process of the packaging structure 100, the upper cover 11 and the end of the cylinder 13 can be directly sleeved. After the sleeve connection is completed, the buffer liner 37 abuts against the outer side of the end of the cylinder 13 close to the upper cover 11. Optionally, the buffer liner 37 can be an integrated annular structure, or it can be spliced ​​by multiple buffer blocks, which is easier to produce and more efficient.

[0096] It can be understood that in one embodiment, the upper cover 11 and the lower cover 15 are connected to the two ends of the cylinder 13 by sleeve connection, and an upper buffer groove 10b and a lower buffer groove 10c are formed between the cylinder 13, respectively, and a buffer liner 37 is provided in each of the upper buffer groove 10b and the lower buffer groove 10c. The buffer liner 37 can be pre-connected with the upper rib 113 or the lower rib 153, and sleeved on the cylinder 13 together with the upper cover 11 or the lower cover 15, and the buffer liner 37 abuts against the outer side of the end of the cylinder 13, so that a multi-layer structure of the upper rib 113-buffer liner 37-cylinder 13-side buffer pad 31 is formed at the upper and lower ends of the packaging structure 100, which can effectively resist the impact force and protect the dishwasher. Furthermore, the upper and lower ends of the packaging structure 100 and the cylinder 13 of the embodiment of the present application are designed with a buffer structure, which can play a buffering role as a whole, and can play a comprehensive protection, effectively resisting the impact force from multiple directions.

[0097] Of course, an upper buffer pad may be attached to the upper cover plate 111, and the upper buffer pad may be made of honeycomb paperboard, so as to resist impact from above and protect the dishwasher.

[0098] In some embodiments, the packaging structure 100 also includes a bundling piece, which can be a rope or a cable tie. After the packaging box, the energy absorbing assembly 30 and the dishwasher are assembled, the bundling piece is wrapped around the outside of the corrugated box 10 to at least block the movement of the upper cover 11 and the lower cover 15 from the cylinder 13, making the structure more compact, ensuring that the packaging box and the energy absorbing assembly 30 can play a role in resisting impact force and protecting the dishwasher as a whole, thereby improving the protective effect of the packaging structure 100.
