Description

Technical Field

[0001] This application belongs to the field of packaging technology, specifically relating to a base pad assembly, a packaging box, and a household appliance assembly. Background Technology

[0002] When transporting household appliances, they need to be wrapped in cardboard boxes to protect them. The cardboard boxes include a paper bottom pad, which supports and secures the appliance; specifically, the bottom pad supports the bottom of the appliance.

[0003] In related technologies, the paper base pads have an unreasonable structural design, lack cushioning features, and have poor cushioning performance. When transporting household appliances, the paper base pads are prone to denting or even breaking under mechanical impact, resulting in a loss of support and inability to effectively protect the appliances. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this application proposes a base pad assembly.

[0006] The second aspect of this application proposes a packaging box.

[0007] A third aspect of this application proposes a household appliance component.

[0008] In view of this, the first aspect of this application proposes a bottom pad assembly, comprising: a cushioning structure, wherein a support portion is provided on one side of the cushioning structure; a corrugated cardboard box, wherein the corrugated cardboard box includes a bottom plate, a side plate and a first flange, wherein the side plate is connected to the outer edge of the bottom plate and the first flange is connected to the side plate; the bottom plate abuts against the side of the cushioning structure opposite to the support portion, the side plate abuts against the outer peripheral wall of the cushioning structure, and the first flange is disposed on the support portion.

[0009] The present application provides a base pad assembly comprising a cushioning structure and a corrugated cardboard box.

[0010] The corrugated cardboard box includes a base plate, side plates, and a first flange. The side plates are connected to the outer edges of the base plate, and the first flange is connected to the side plates.

[0011] The cushioning structure is installed inside the corrugated cardboard box. Specifically, the bottom plate abuts against the side of the cushioning structure away from the support, the side plate abuts against the outer peripheral wall of the cushioning structure, and the first flange covers the support. That is, the cushioning structure is located between the first flange and the bottom plate.

[0012] When the item to be packaged (e.g., a household appliance) is placed on the base assembly, the bottom of the item to be packaged abuts against the first flange. In other words, the support is supported on the bottom of the item to be packaged by the first flange.

[0013] The base pad assembly includes a cushioning structure with a support portion on one side. The support portion supports the packaged item, which is placed on the support portion. The cushioning structure has good cushioning performance, thus enhancing the cushioning performance of the base pad assembly. When subjected to mechanical impact, the cushioning structure can absorb impact force, disperse pressure, and provide shock absorption protection. It can reduce the external force acting on the packaged item, reduce the deformation of the packaged item caused by external impact, and provide impact protection for the packaged item. It can also ensure the packaged item's dimensions and performance. The base pad assembly can stably support the packaged item.

[0014] The base pad assembly also includes a corrugated cardboard box. The corrugated cardboard box has excellent compression resistance, allowing it to wrap around the bottom, sides, and support sections of the cushioning structure. This enhances the cushioning performance of the base pad assembly while strengthening its overall structural strength and stability, ensuring its pressure-bearing capacity and reducing the probability of deformation under mechanical impact. This guarantees the effectiveness and reliability of supporting the packaged items. Furthermore, the first flange of the corrugated cardboard box is positioned on the support section. That is, the first flange partially closes or covers the top of the cushioning structure, further enhancing the overall structural stability of the base pad assembly and improving its compression and impact resistance.

[0015] It is understandable that the cushioning structure and the corrugated cardboard box are not two independent structures. The first flange and the support are connected, and the cushioning structure is located between the first flange and the base plate. Therefore, the cushioning structure and the corrugated cardboard box are assembled into a whole, which can enhance the stability and strength of the overall structure.

[0016] Therefore, it can be seen that the structure of the bottom pad assembly is reasonably designed, which can improve the cushioning performance of the bottom pad assembly, while ensuring the overall pressure resistance and impact resistance of the bottom pad assembly, effectively protecting the packaged items placed on the bottom pad assembly, and improving the performance of the bottom pad assembly.

[0017] In some technical solutions, optionally, there are multiple support parts and multiple first flanges, with multiple support parts arranged at intervals, and each first flange covering at least one support part.

[0018] In this technical solution, there are multiple support parts and multiple first flanges, with each first flange covering at least one support part. That is, each support part is covered with a first flange, ensuring the coverage area of ​​the corrugated cardboard box and the top of the cushioning structure. This is equivalent to forming multiple fixing points on the top of the cushioning structure, firmly connecting the corrugated cardboard box and the cushioning structure at multiple locations. This enhances the connection strength between the corrugated cardboard box and the cushioning structure, improves the overall structural stability of the base pad assembly, and enhances its compression and impact resistance.

[0019] Furthermore, by incorporating multiple support components, the contact area between the base pad assembly and the packaged item can be increased. This is equivalent to setting multiple localized load-bearing and positioning points on the base pad assembly, preventing the weight of the packaged item from being concentrated in one place. Instead, the weight is distributed across multiple support components, which helps reduce the risk of localized deformation or crushing. The combined effect of multiple support components enhances the overall vibration resistance, meeting the needs of long-distance transportation or heavy-duty logistics environments.

[0020] In some technical solutions, optionally, along the circumference of the buffer structure, the side plate includes multiple sub-plates connected end to end; each sub-plate includes a plate body and two ends, with the plate body connected between the two ends; the plate bodies of two adjacent sub-plates are located on different sides of the buffer structure, each end of one sub-plate is a tongue, and each end of the other sub-plate is a bend, the bend including a first bend segment and a second bend segment, the first bend segment being connected between the second bend segment and the bottom plate, the second bend segment being located between the first bend segment and the buffer structure, and the tongue being inserted between the first bend segment and the second bend segment.

[0021] In this technical solution, the structure of the side plate is refined.

[0022] Along the circumference of the buffer structure, the side plate includes multiple sub-plates, which are connected end to end in sequence.

[0023] Each sub-board consists of a body and two ends, with the body connected between the two ends.

[0024] Two adjacent sub-plates are defined as the first plate and the second plate, respectively. The first plate includes a plate body and two ends, and the second plate includes a plate body and two ends. The plate bodies of the first plate and the second plate are located on different sides of the buffer structure. Each end of the first plate body is a tongue. Each end of the second plate body is a bend, and the tongue is inserted into the bend.

[0025] The bending section includes a first bending segment and a second bending segment. The first bending segment connects the second bending segment and the base plate. The second bending segment is bent relative to the first bending segment; specifically, the second bending segment is located between the first bending segment and the buffer structure. That is, the first and second bending segments are bent to form an angular structure, and a tongue is inserted between the first and second bending segments. The tongue and the bending section cooperate to form a splicing structure, specifically, an embedded snap-fit ​​structure, thereby achieving a stable connection between adjacent sub-plates and effectively preventing loosening, detachment, or misalignment between sub-plates. When subjected to external impact, multiple sub-plates cooperate to maintain the overall dimensions of the side plates, reduce the probability of side plate deformation, improve overall rigidity and vibration resistance, and enhance the protection of the packaged items.

[0026] Understandably, the side panel consists of multiple sub-panels. The side panel is not formed by bending a single piece of corrugated paper, but by connecting multiple sub-panels end to end. Each sub-panel can be cut individually, making it suitable for mass production and automated operations.

[0027] In addition, the cooperative structure of multiple sub-boards allows each sub-board to adapt to the external dimensions of the cushioning structure by adjusting the dimensions of the connection between adjacent sub-boards, thus ensuring the effective assembly dimensions of the corrugated cardboard box and the cushioning structure.

[0028] In some technical solutions, optionally, the body of each sub-board is connected to at least one first flange.

[0029] In this technical solution, the mating structure between the sub-board and the first flange is refined.

[0030] Specifically, each sub-board body is connected to at least one first flange, that is, the sub-board body serves as the connecting carrier for the first flange, and the first flange is bent from the board body to cover the support. The first flange is not isolated on the support, but is connected to the corresponding sub-board body.

[0031] Since the panels of two adjacent sub-boards are located on different sides of the cushioning structure, and each sub-board is connected to at least one first flange, after the corrugated box and the cushioning structure are assembled, multiple first flanges can be connected to multiple supports on the cushioning structure from different sides. Multiple first flanges bend and extend to the supports from multiple directions and connect to the supports. The corrugated box and the cushioning structure are firmly combined at multiple angles and multiple positions, which can enhance the connection strength of the corrugated box and the cushioning structure, which is conducive to enhancing the overall structural stability of the bottom pad assembly and improving the compression and impact resistance of the bottom pad assembly.

[0032] In some technical solutions, optionally, the multiple sub-boards include a first sub-board and a second sub-board, the body of the first sub-board is connected to at least one first flange, the corrugated cardboard box also includes a second flange, the body of the second sub-board is connected to the second flange, and the second flange covers the portion of the cushioning structure located on the periphery of the support.

[0033] In this technical solution, the matching structure of the corrugated cardboard box and the cushioning structure is refined.

[0034] The multiple sub-boards are classified into different types, including a first sub-board and a second sub-board. The first sub-board is used to cooperate with the first flange, and the second sub-board is used to cooperate with the second flange of the corrugated cardboard box.

[0035] Specifically, the body of the first sub-plate is connected to at least one first flange, and the body of the second sub-plate is connected to a second flange. The first flange is connected to the support portion of the buffer structure and covers the support portion. The second flange is connected to the portion of the buffer structure located around the support portion and covers the portion of the buffer structure located around the support portion.

[0036] Understandably, the number and arrangement of the support components are designed according to load-bearing requirements. When it cannot be guaranteed that each sub-board can cooperate with the first flange, a second flange can be set to connect with the second sub-board and cover the part of the buffer structure located around the support component. In this way, after the corrugated cardboard box and the buffer structure are assembled, the first flange and the second flange cooperate to connect with the buffer structure from different sides. The first flange and the second flange cooperate to bend and extend to the top of the buffer structure from multiple directions. The corrugated cardboard box and the buffer structure are firmly combined at multiple angles and positions, which can enhance the connection strength between the corrugated cardboard box and the buffer structure, which is conducive to enhancing the overall structural stability of the base pad assembly and improving the compression and impact resistance of the base pad assembly.

[0037] In some technical solutions, the base pad assembly may optionally include paper corner protectors, which surround the cushioning structure, and both the side plates and the bottom plate abut against the cushioning structure through the paper corner protectors.

[0038] In this technical solution, the base pad assembly also includes paper corner protectors, which surround the cushioning structure. Specifically, one part of the paper corner protector is located between the cushioning structure and the side panels, while the other part is located between the cushioning structure and the base plate. The paper corner protectors are connected to the cushioning structure, the side panels abut against the cushioning structure via the paper corner protectors, and the base plate abuts against the cushioning structure via the paper corner protectors.

[0039] Understandably, the paper corner protectors have a circular structure, which can enhance the impact resistance at the corners of the base pad assembly. This helps to reduce the deformation of the base pad assembly when using straps to bind it, ensuring that the size of the base pad assembly can effectively support the packaged item.

[0040] Understandably, paper corner protectors serve to reinforce edges and corners. They possess a certain degree of rigidity, support, compression resistance, and cushioning, connecting the cushioning structure and the corrugated cardboard box, thus enhancing overall structural stability. By using paper corner protectors, a stable and flat contact surface is provided for the side panels and bottom panel, allowing them to be securely assembled to the cushioning structure indirectly through the corner protectors. The corner protectors also create a more uniform and tighter contact between the side panels and the cushioning structure, reducing local gaps.

[0041] Understandably, the corners of the cushioning structure are areas of concentrated stress and are prone to damage, especially during transportation when they are easily subjected to squeezing, collisions, or friction. Because the paper corner protectors surround the cushioning structure, they can cover the weakest areas, providing reinforcement and support. Furthermore, since the paper corner protectors are located between the cushioning structure and the side panels, they can distribute some of the pressure, reducing localized stress on the corrugated box and lowering the probability of bending or even denting.

[0042] In some technical solutions, the paper corner protector may optionally include: a bottom corner protector located between the cushioning structure and the base plate, with an opening in the middle; and a side corner protector connected to the outer edge of the bottom corner protector, located between the cushioning structure and the side plate, surrounding the cushioning structure, with the height of the side corner protector less than the height of the cushioning structure along the direction from the base plate to the cushioning structure.

[0043] In this technical solution, the structure of the paper corner protectors is refined.

[0044] Paper corner protectors include bottom corner protectors and side corner protectors. The outer edges of the side corner protectors are connected to those of the bottom corner protectors. The bottom corner protector is located between the cushioning structure and the base plate, while the side corner protectors are located between the cushioning structure and the side plates, and the side corner protectors are arranged around the cushioning structure.

[0045] The bottom corner protector has an opening in the middle, which enhances the impact resistance of the bottom pad assembly at the corner while reducing the material input of the bottom corner protector, thus helping to reduce the production cost of the product.

[0046] Along the direction from the base plate to the cushioning structure, the height of the side corner protectors is less than the height of the cushioning structure. This defines the relationship between the height of the side corner protectors and the height of the cushioning structure. In other words, the side corner protectors are located lower on the cushioning structure. The lower part of the cushioning structure is where stress is concentrated and where damage is more likely. Therefore, by setting the position of the side corner protectors, the effectiveness of the paper corner protectors in reinforcing the edges and corners can be ensured while reducing the material input for the side corner protectors, which helps to reduce the production cost of the base pad assembly. In addition, the position of the side corner protectors also prevents interference between the paper corner protectors and the packaged item, which helps to reduce the assembly difficulty of the packaged item and the base pad assembly and improves assembly efficiency.

[0047] In some technical solutions, the cushioning structure may optionally be a honeycomb paper structure; or the cushioning structure may be a vertical corrugated paper structure; or a portion of the cushioning structure may be a honeycomb paper structure and the other portion of the cushioning structure may be a vertical corrugated paper structure.

[0048] In this technical solution, the structure of the buffer device is refined.

[0049] The cushioning structure is a honeycomb paper structure. Alternatively, the cushioning structure is a vertical corrugated paper structure. Or, part of the cushioning structure is a honeycomb paper structure, and the other part is a vertical corrugated paper structure.

[0050] Honeycomb paper structures have excellent cushioning performance, high strength and rigidity per unit weight, which is conducive to recovery of deformation after compression, has good resilience, and is not prone to failure.

[0051] Vertical corrugated paper structures offer excellent cushioning capabilities, absorbing shock and dispersing stress. They effectively resist pressure from above and below, exhibiting strong load-bearing capacity. The vertical corrugation refers to the corrugations being perpendicular to the paperboard plane, providing strong compressive strength in the vertical direction. Vertical corrugated paper structures also offer good shock absorption and cushioning performance, effectively absorbing impact forces.

[0052] In some technical solutions, optionally, the side of the buffer structure with the support part is also provided with a limiting part, the limiting part is arranged separately from the support part, and the limiting part is used to limit the packaged item; wherein, along the direction from the bottom plate to the buffer structure, the height of the side of the limiting part away from the bottom plate is lower than the height of the side of the support part away from the bottom plate.

[0053] In this technical solution, the buffer structure is also provided with a limiting part, and the limiting part and the supporting part are located on the same side of the buffer structure.

[0054] The limiting part and the supporting part are arranged separately, meaning that there is no interference between the limiting part and the supporting part. When the packaged item is placed on the base pad assembly, the limiting part is used to limit the packaged item to restrict the displacement of the packaged item relative to the base pad assembly. This prevents the packaged item from moving, shaking, or deflecting, and ensures the effective fit between the packaged item and the supporting part, thus ensuring the effectiveness and reliability of the base pad assembly in supporting the packaged item.

[0055] Specifically, along the direction from the base plate to the buffer structure, the height of the side of the limiting part away from the base plate is lower than the height of the side of the supporting part away from the base plate. That is, the distance from the side of the limiting part away from the base plate to the base plate is less than the distance from the side of the supporting part away from the base plate to the base plate. The supporting part is used to support the packaged item. When the packaged item is placed on the base pad assembly, the limiting part will not interfere with the assembly of the packaged item and the supporting part; that is, the limiting part will not push the packaged item upwards, ensuring that the packaged item effectively rests on the supporting part, ensuring the contact area between the packaged item and the first flange, preventing the packaged item from tilting, and ensuring that the supporting part can provide a stable load-bearing foundation.

[0056] In some technical solutions, the limiting part may optionally include at least one of a limiting groove and a limiting hole.

[0057] In this technical solution, the structure of the limiting part is refined.

[0058] The limiting portion includes at least one of a limiting groove and a limiting hole. That is, the limiting portion includes a limiting groove, or the limiting portion includes a limiting hole, or the limiting portion includes both a limiting groove and a limiting hole.

[0059] Once the packaged item is placed on the base assembly, the positioning part of the packaged item will insert into the limiting part. For example, the positioning part will insert into the limiting hole, or the positioning part will insert into the limiting groove. The structure of the limiting part can increase the limiting area of ​​the limiting part and the packaged item, and can limit the packaged item from multiple directions and multiple positions, effectively preventing the packaged item from moving, shaking, and deflecting.

[0060] In some technical solutions, optionally, the buffer structure includes: a buffer body located between the support and the base plate; when the limiting part includes a limiting groove, the limiting part includes a first protrusion and a second protrusion, both the first protrusion and the second protrusion being connected to the side of the buffer body away from the base plate, the first protrusion and the second protrusion being arranged at intervals to enclose the limiting groove; when the limiting part includes a limiting hole, the limiting hole is provided in the buffer body.

[0061] In this technical solution, the buffer structure includes a buffer body, which is located between the support and the base plate, and the support is connected to the buffer body.

[0062] When the limiting part includes a limiting groove, the limiting part includes a first protrusion and a second protrusion, both of which are connected to the side of the buffer body opposite to the bottom plate. That is, the first protrusion, the second protrusion, and the support part are located on the same side of the buffer body, and any one of the first protrusion, the second protrusion, and the support part is connected to the buffer body. The first protrusion and the second protrusion are arranged at intervals to enclose the limiting groove. The positioning part of the packaged item extends between the first protrusion and the second protrusion to limit the packaged item from multiple directions and angles, effectively preventing the packaged item from moving, shaking, or deflecting.

[0063] When the limiting part includes a limiting hole, the limiting hole is located in the buffer body, and the positioning part of the packaged item will extend into the limiting hole to limit the packaged item from multiple directions and multiple angles, which can effectively prevent the packaged item from moving, shaking and deflecting.

[0064] In some technical solutions, optionally, the number of limiting holes is multiple, and the multiple limiting holes include at least a first limiting hole and a second limiting hole; when the limiting part includes a limiting groove and a first limiting hole, the first limiting hole is located between the first protrusion and the second protrusion; when the limiting part includes a limiting groove and a second limiting hole, the second limiting hole is arranged separately from the limiting groove.

[0065] In this technical solution, there are multiple limiting holes, which are categorized into different types, including at least a first limiting hole and a second limiting hole. The first limiting hole and the second limiting hole are located in different positions.

[0066] When the limiting part includes a limiting groove and a first limiting hole, the first limiting hole is located between the first protrusion and the second protrusion. That is, it defines the positional relationship between the limiting groove and the first limiting hole. The positioning part of the packaged item can extend into the first limiting hole while extending into the limiting groove, so as to increase the limiting area of ​​the positioning part and the limiting part, and effectively prevent the packaged item from moving, shaking and deflecting.

[0067] When the limiting part includes a limiting groove and a second limiting hole, the second limiting hole is arranged separately from the limiting groove. That is, the positional relationship between the limiting groove and the second limiting hole is defined. The limiting groove and the second limiting hole can be limited and engaged with different positioning parts of the packaged item. Through multiple positions and multiple limiting engagement structures, the displacement of the packaged item relative to the base pad assembly is jointly restricted, providing structural support to effectively prevent the packaged item from moving, shaking and deflecting.

[0068] In some technical solutions, optionally, the buffer body includes: a first buffer portion; a second buffer portion, the first buffer portion being located between the support portion and the second buffer portion; when the limiting portion includes a first protrusion and a second protrusion, the first protrusion, the second protrusion, and the support portion are located on the same side of the first buffer portion; when the limiting portion includes a limiting hole, the limiting hole penetrates through the first buffer portion.

[0069] In this technical solution, the buffer body includes a first buffer part and a second buffer part. The first buffer part is located between the support part and the second buffer part, which defines the positional relationship between the first buffer part, the second buffer part and the support part.

[0070] The first and second buffer parts work together to ensure the thickness of the buffer structure in the direction from the base plate to the buffer structure, which in turn ensures the positional relationship between the support part and the packaged item, so that the support part can effectively support the packaged item.

[0071] When the limiting part includes a first protrusion and a second protrusion, the first protrusion, the second protrusion and the support part are located on the same side of the first buffer part. The first buffer part serves as the mounting carrier for the first protrusion, the second protrusion and the support part, and has the function of mounting and fixing the first protrusion, the second protrusion and the support part.

[0072] When the limiting part includes a limiting hole, the limiting hole penetrates the first buffer part; that is, the limiting hole penetrates the first buffer part, but the limiting part does not penetrate the second buffer part. This not only satisfies the insertion and mating requirements between the positioning part of the packaged item and the limiting hole, but also reduces the volume of the limiting hole, decreases the area where the limiting hole is located on the buffer body, ensures the structural strength and rigidity of the buffer body, and guarantees the buffering effect of the buffer body.

[0073] Optionally, in some technical solutions, the first buffer portion includes: a first buffer layer, wherein, if the limiting portion includes a second limiting hole, the second limiting hole penetrates the first buffer layer; a second buffer layer, wherein the first buffer layer is located between the support portion and the second buffer layer, and the first buffer portion is cross-sectioned along a direction perpendicular to the base plate to the first flange, the cross-sectional area of ​​the second buffer layer is larger than the cross-sectional area of ​​the first buffer layer, and a portion of the second buffer layer protrudes from the outer peripheral wall of the first buffer layer; if the limiting portion includes a first protrusion and a second protrusion, both the first protrusion and the second protrusion are located on the portion of the second buffer layer protruding from the first buffer layer; if the limiting portion includes a first limiting hole, the first limiting hole penetrates the second buffer layer.

[0074] In this technical solution, the first buffer part includes a first buffer layer and a second buffer layer.

[0075] The first buffer layer is located between the support and the second buffer layer.

[0076] The bottom pad assembly is cross-sectioned along a direction perpendicular to the first buffer layer to the second buffer layer. The cross-sectional area of ​​the second buffer layer is larger than that of the first buffer layer, wherein a portion of the second buffer layer protrudes from the outer peripheral wall of the first buffer layer.

[0077] When the limiting part includes a second limiting hole, the second limiting hole penetrates the first buffer layer, but does not penetrate the second buffer layer. This not only meets the usage requirements of the positioning part of the packaged item and the second limiting hole for insertion and matching, but also reduces the volume of the second limiting hole and the area where the second limiting hole is set in the first buffer part, ensuring the structural strength and rigidity of the buffer body and ensuring the buffering effect of the buffer body.

[0078] When the limiting part includes a first protrusion and a second protrusion, both the first and second protrusions are located on the portion of the second buffer layer that protrudes beyond the first buffer layer. That is, the portion of the second buffer layer that protrudes beyond the first buffer layer serves as the mounting carrier for the first and second protrusions, functioning to install and fix them. It is understood that by utilizing the area difference between the first and second buffer layers, the first and second protrusions are positioned on the second buffer layer, while the first buffer layer avoids them, thus meeting the insertion requirements of the positioning part of the packaged item and the limiting groove. It is also understood that the portion of the second buffer layer protruding beyond the first buffer layer and the first buffer layer enclose a recessed platform, thereby reducing the installation height of the first and second protrusions. This results in the height of the side of the limiting part away from the bottom plate along the direction from the bottom plate to the buffer structure being lower than the height of the side of the support part away from the bottom plate. Therefore, by setting a mating structure between the first and second buffer layers, the effectiveness of the limiting groove setting can be ensured while reducing the material input of the first buffer part, which is beneficial for reducing the production cost of the base pad assembly.

[0079] When the limiting part includes a first limiting hole, the first limiting hole penetrates the second buffer layer. The portion of the second buffer layer protruding beyond the first buffer layer is not obstructed by the first buffer layer, and the portion of the second buffer layer protruding beyond the first buffer layer is exposed. By allowing the first limiting hole to penetrate the second buffer layer, the first buffer layer does not obstruct the first limiting hole, thus satisfying the usage requirements for the insertion and mating of the positioning part of the packaged item with the first limiting hole. Therefore, by setting a mating structure of the first and second buffer layers, while ensuring the effectiveness of the first limiting hole setting, the material input of the first buffer part can be reduced, which is beneficial to reducing the production cost of the base pad assembly.

[0080] Furthermore, the stacking of the first and second buffer layers creates a multi-layered energy absorption path. When an external impact force acts on the base pad assembly, the first and second buffer layers respond sequentially, gradually compressing to delay impact transmission and disperse impact energy. This prevents the impact from concentrating on a single point in either the first or second buffer layer, thus improving the buffering performance of the buffer structure, enabling rapid absorption of impact energy, and achieving effective energy dispersion.

[0081] In addition, the first and second buffer layers are designed in a layered manner so that the impact force is not concentrated in the first or second buffer layer, but is shared by the first and second buffer layers. This can effectively reduce the risk of local crushing and deformation and effectively protect the packaged items.

[0082] In some technical solutions, optionally, at least a portion of the corners of the first buffer layer are provided with notches, and the second limiting hole is disposed opposite to the notch.

[0083] In this technical solution, the structure of the first buffer layer is refined.

[0084] Along the circumference of the buffer structure, the sidewall of the first buffer layer includes multiple sub-walls connected end to end. Any two adjacent sub-walls extend in different directions, and the connection point between two adjacent sub-walls is the corner of the first buffer layer.

[0085] The first buffer layer has multiple corners, and at least some of the corners have notches. The notches are used to avoid the structural components (such as hinges) at the bottom of the item to be packaged, so as to avoid interference with the structural components of the item to be packaged. The structure of the notches not only avoids the structural components of the item to be packaged, but also does not increase the thickness of the bottom pad assembly.

[0086] The second limiting hole is set opposite to the notch, the setting position of the second limiting hole matches the position of the positioning part of the part to be packaged, and the setting position of the notch matches the position of the structural part of the part to be packaged.

[0087] In some technical solutions, the second buffer may optionally include multiple third buffer layers, which are stacked together.

[0088] In this technical solution, the structure of the second buffer section is refined. The second buffer section includes multiple third buffer layers, which are stacked. Each third buffer layer has good elasticity, compressibility, and resilience. When multiple third buffer layers are stacked together, they can form a multi-layered energy absorption path. When an external impact force acts on the base pad assembly, the different third buffer layers respond sequentially, and the multiple third buffer layers are gradually compressed, thereby delaying the transmission of impact and dispersing the impact energy. This prevents the impact from concentrating on a certain third buffer layer or a certain point in the second buffer section, which is beneficial to improving the buffering performance of the buffer structure, achieving rapid absorption of impact energy, and effectively dispersing energy.

[0089] In addition, multiple third buffer layers can more effectively absorb and mitigate the impact from the outside world compared to a single third buffer layer. By setting up layers, the impact force is not concentrated on a single third buffer layer, but is shared by multiple third buffer layers, which can effectively reduce the risk of local crushing and deformation, and effectively protect the packaged items.

[0090] The second aspect of this application proposes a packaging box comprising: a base pad assembly as described in the first aspect.

[0091] The packaging box provided in this application includes the base pad assembly as described in the first aspect, and therefore has all the beneficial effects of the aforementioned base pad assembly, which will not be described in detail here.

[0092] A third aspect of this application provides a household appliance assembly, comprising: a household appliance; and a base assembly as in the first aspect; or a packaging box as in the second aspect, the packaging box covering the household appliance; the household appliance being located on the base assembly, a first flange being located between the household appliance and a support portion, and at least a portion of the positioning portion of the household appliance being detachably inserted into the limiting portion of the base assembly.

[0093] The household appliance components provided in this application include, as in the first aspect, the base pad assembly or as in the second aspect, and therefore have all the beneficial effects of the aforementioned base pad assembly, which will not be described in detail here.

[0119] The following is combined with Figures 1 to 17 This invention describes the base pad assembly 10, the packaging box, and the household appliance assembly 50, according to embodiments of the present invention.

[0120] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the bottom pad assembly 10 according to some embodiments of the present invention includes: a buffer structure 100, a support portion 110 provided on one side of the buffer structure 100; a corrugated cardboard box 200, the corrugated cardboard box 200 including a bottom plate 210, a side plate 220 and a first flange 230, the side plate 220 being connected to the outer edge of the bottom plate 210, and the first flange 230 being connected to the side plate 220; the bottom plate 210 abutting against the side of the buffer structure 100 away from the support portion 110, the side plate 220 abutting against the outer peripheral wall 102 of the buffer structure, and the first flange 230 covering the support portion 110.

[0121] According to an embodiment of the present invention, the bottom pad assembly 10 includes a cushioning structure 100 and a corrugated cardboard box 200.

[0122] The corrugated cardboard box 200 includes a base plate 210, a side plate 220 and a first flange 230. The side plate 220 is connected to the outer edge of the base plate 210, and the first flange 230 is connected to the side plate 220.

[0123] The cushioning structure 100 is installed inside the corrugated cardboard box 200. Specifically, the bottom plate 210 abuts against the side of the cushioning structure 100 away from the support portion 110, the side plate 220 abuts against the outer peripheral wall 102 of the cushioning structure, and the first flange 230 covers the support portion 110. That is, the cushioning structure 100 is located between the first flange 230 and the bottom plate 210.

[0124] When the item to be packaged (e.g., household appliance 500) is placed on the base assembly 10, the bottom of the item to be packaged abuts against the first flange 230. In other words, the support part 110 is supported on the bottom of the item to be packaged by the first flange 230.

[0125] The base pad assembly 10 includes a buffer structure 100, with a support portion 110 on one side. The support portion 110 supports the packaged item. The packaged item is placed on the support portion 110. The buffer structure 100 has good buffering performance, thus enhancing the buffering performance of the base pad assembly 10. When subjected to mechanical impact, the buffer structure 100 can absorb impact force, disperse pressure, and provide shock absorption protection. It can reduce the external force acting on the packaged item, reduce the deformation of the packaged item caused by external impact, and provide impact protection for the packaged item. It can ensure the external dimensions and performance of the packaged item. The base pad assembly 10 can stably support the packaged item.

[0126] The base pad assembly 10 also includes a corrugated cardboard box 200. The corrugated cardboard box 200 has good compression resistance, allowing it to wrap around the bottom, sides, and support portion 110 of the cushioning structure 100. This enhances the cushioning performance of the base pad assembly 10 while strengthening its overall structural strength and stability, ensuring its pressure-bearing capacity, and reducing the probability of deformation under mechanical impact. This ensures the effectiveness and reliability of supporting the packaged item. Furthermore, the first flange 230 of the corrugated cardboard box 200 covers the support portion 110, meaning the first flange 230 partially closes or covers the top of the cushioning structure 100, further enhancing the overall structural stability of the base pad assembly 10 and improving its compression and impact resistance.

[0127] It is understandable that the cushioning structure 100 and the corrugated cardboard box 200 are not two independent structures. The first flange 230 is connected to the support part 110, and the cushioning structure 100 is located between the first flange 230 and the base plate 210. Therefore, the cushioning structure 100 and the corrugated cardboard box 200 are assembled into a whole, which can enhance the stability and strength of the overall structure.

[0128] Therefore, it can be seen that the structure of the bottom pad assembly 10 is reasonably designed in this application, which can improve the cushioning performance of the bottom pad assembly 10, while ensuring the overall pressure resistance and impact resistance of the bottom pad assembly 10, effectively protecting the packaged items placed on the bottom pad assembly 10, and improving the performance of the bottom pad assembly 10.

[0129] According to some embodiments of the present invention, there are multiple support portions 110 and multiple first flanges 230, with multiple support portions 110 arranged at intervals, and each first flange 230 covering at least one support portion 110.

[0130] Specifically, there are multiple support portions 110 and multiple first flanges 230, with each first flange 230 covering at least one support portion 110. That is, each support portion 110 is covered with a first flange 230, which ensures the coverage area of ​​the corrugated cardboard box 200 and the top of the cushioning structure 100. This is equivalent to forming multiple fixing points on the top of the cushioning structure 100, and the corrugated cardboard box 200 and the cushioning structure 100 are firmly connected at multiple locations, enhancing the connection strength between the corrugated cardboard box 200 and the cushioning structure 100. This is beneficial to enhancing the overall structural stability of the base pad assembly 10 and improving the pressure resistance and impact resistance of the base pad assembly 10.

[0131] Furthermore, by providing multiple support parts 110, the contact area between the base pad assembly 10 and the packaged item can be increased. This is equivalent to setting multiple local load-bearing and positioning points on the base pad assembly 10. The weight of the packaged item will not be concentrated in one place, but will be distributed through multiple support parts 110, which helps reduce the risk of local deformation or crushing. The combined effect of multiple support parts 110 can enhance the overall vibration resistance and meet the usage requirements of long-distance transportation or heavy logistics environments.

[0132] It is understood that each first flange 230 is disposed on at least one support portion 110, that is, the first flange 230 can cooperate with one support portion 110, and the first flange 230 can also cooperate with multiple support portions 110.

[0133] For example, multiple first flanges 230 and multiple support portions 110 are matched one-to-one.

[0134] For example, in a portion of a plurality of first flanges 230, the first flange 230 engages with a support portion 110.

[0135] For example, in a portion of the plurality of first flanges 230, the first flange 230 cooperates with a plurality of support portions 110.

[0136] For example, such as Figure 2As shown in the figures, the plurality of supporting portions 110 enclose a "hollow square" shaped structure, which can reduce the number of the supporting portions 110 while ensuring effective support for a to-be-packaged article, can reduce material input of the supporting portions 110, and is beneficial to reducing production cost of the base pad assembly 10.

[0137] In some embodiments according to the present utility model, as Figure 2 , Figure 9 and Figure 10 shown, along the circumferential direction of the buffer structure 100, the side plate 220 comprises a plurality of sub-plates 221 connected end to end in sequence; the sub-plate 221 comprises a plate body 222 and two end portions 223, and the plate body 222 is connected between the two end portions 223; the plate bodies 222 of two adjacent sub-plates 221 are located at different sides of the buffer structure 100, each end portion 223 of one sub-plate 221 is an insertion tongue 223a, and each end portion 223 of the other sub-plate 221 is a bent portion 223b, the bent portion 223b comprises a first bending section 224 and a second bending section 225, the first bending section 224 is connected between the second bending section 225 and the bottom plate 210, the second bending section 225 is located between the first bending section 224 and the buffer structure 100, and the insertion tongue 223a is inserted between the first bending section 224 and the second bending section 225.

[0138] Specifically, the structure of the side plate 220 is refined.

[0139] Along the circumferential direction of the buffer structure 100, the side plate 220 comprises a plurality of sub-plates 221, and the plurality of sub-plates 221 are connected end to end in sequence.

[0140] Each sub-plate 221 comprises a plate body 222 and two end portions 223, and the plate body 222 is connected between the two end portions 223.

[0141] Two adjacent sub-plates 221 are respectively defined as a first plate and a second plate, the first plate comprises a plate body 222 and two end portions 223, and the second plate comprises a plate body 222 and two end portions 223. The plate body 222 of the first plate and the plate body 222 of the second plate are located at different sides of the buffer structure 100. Each end portion 223 of the first plate body 222 is an insertion tongue 223a. Each end portion 223 of the second plate body 222 is a bent portion 223b, and the insertion tongue 223a is inserted into the bent portion 223b.

[0142] The bending portion 223b includes a first bending segment 224 and a second bending segment 225. The first bending segment 224 is connected between the second bending segment 225 and the base plate 210. The second bending segment 225 is bent relative to the first bending segment 224. Specifically, the second bending segment 225 is located between the first bending segment 224 and the buffer structure 100. That is, the first bending segment 224 and the second bending segment 225 are bent to form an angled structure, and the tongue 223a is inserted between the first bending segment 224 and the second bending segment 225. The tongue 223a and the bending portion 223b cooperate to form a splicing structure, specifically, an embedded snap-fit ​​structure, thereby achieving a stable connection between adjacent sub-plates 221 and effectively preventing the sub-plates 221 from loosening, falling off, or misaligning. When subjected to external impact, the multiple sub-plates 221 cooperate with each other to maintain the overall shape and size of the side plate 220, reduce the probability of deformation of the side plate 220, improve the overall rigidity and vibration resistance, and enhance the protection of the packaged items.

[0143] It is understandable that the side panel 220 includes multiple sub-panels 221. The side panel 220 is not formed by bending a whole piece of corrugated paper, but by connecting multiple sub-panels 221 end to end. Each sub-panel 221 can be cut individually, which is suitable for mass production and automated operation.

[0144] In addition, the cooperative structure of multiple sub-boards 221 allows each sub-board 221 to adapt to the external dimensions of the buffer structure 100 by adjusting the size of the connection between adjacent sub-boards 221, thus ensuring the effective assembly size of the corrugated cardboard box 200 and the buffer structure 100.

[0145] It is understandable that the side plate 220 abuts against the buffer structure 100. Therefore, the buffer structure 100 can compress the second bending section 225 to ensure the matching dimensions of the tongue 223a and the bending part 223b, and to ensure the stability and reliability of the connection of the side plate 220.

[0146] It is understandable that, such as Figure 9 As shown, the corrugated cardboard box 200 is provided with pressure lines 400, and the corrugated cardboard box 200 is formed by folding.

[0147] For example, an adhesive layer is provided at the connection between the tongue 223a and the bend 223b to ensure that the tongue 223a and the bend 223b are firmly connected together.

[0148] According to some embodiments of the present invention, the plate body 222 of each sub-plate 221 is connected to at least one first flange 230.

[0149] Specifically, the mating structure between the sub-plate 221 and the first flange 230 is refined.

[0150] Each sub-board 221 has its body 222 connected to at least one first flange 230. That is, the body 222 of the sub-board 221 serves as the connecting carrier for the first flange 230, which is bent from the body 222 to cover the support portion 110. The first flange 230 is not isolated on the support portion 110, but is connected to the body 222 of the corresponding sub-board 221.

[0151] Since the plates 222 of two adjacent sub-plates 221 are located on different sides of the buffer structure 100, and the plate 222 of each sub-plate 221 is connected to at least one first flange 230, after the corrugated box 200 and the buffer structure 100 are assembled, multiple first flanges 230 can be connected to multiple support portions 110 on the buffer structure 100 from different sides of the buffer structure 100. Multiple first flanges 230 bend and extend to the support portions 110 from multiple directions and are connected to the support portions 110. The corrugated box 200 and the buffer structure 100 are firmly combined at multiple angles and multiple positions, which can enhance the connection strength between the corrugated box 200 and the buffer structure 100, which is beneficial to enhancing the overall structural stability of the bottom pad assembly 10 and improving the pressure resistance and impact resistance of the bottom pad assembly 10.

[0152] According to some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 , Figure 10 and Figure 11 As shown, the plurality of sub-boards 221 include a first sub-board 221a and a second sub-board 221b. The board body 222 of the first sub-board 221a is connected to at least one first flange 230. The corrugated cardboard box 200 also includes a second flange 240. The board body 222 of the second sub-board 221b is connected to the second flange 240. The second flange 240 covers the portion of the buffer structure 100 located around the support portion 110.

[0153] Specifically, the matching structure of the corrugated cardboard box 200 and the cushioning structure 100 is refined.

[0154] The multiple sub-boards 221 are classified into different types, such that the multiple sub-boards 221 include a first sub-board 221a and a second sub-board 221b. The first sub-board 221a is used to cooperate with the first flange 230, and the second sub-board 221b is used to cooperate with the second flange 240 of the corrugated cardboard box 200.

[0155] Specifically, the body 222 of the first sub-plate 221a is connected to at least one first flange 230, and the body 222 of the second sub-plate 221b is connected to a second flange 240. The first flange 230 is connected to the support portion 110 of the buffer structure 100 and covers the support portion 110. The second flange 240 is connected to the portion of the buffer structure 100 located around the support portion 110 and covers the portion of the buffer structure 100 located around the support portion 110.

[0156] Understandably, the number and arrangement of the support parts 110 are designed according to the load-bearing requirements. When it cannot be guaranteed that each sub-board 221 can cooperate with the first flange 230, a second flange 240 can be set to connect the second flange 240 with the second sub-board 221b and cover the portion of the buffer structure 100 located around the support part 110. In this way, after the corrugated cardboard box 200 and the buffer structure 100 are assembled, the first flange 230 and the second flange 240 cooperate and can connect with the buffer structure 100 from different sides. The first flange 230 and the second flange 240 cooperate to bend and extend to the top of the buffer structure 100 from multiple directions. The corrugated cardboard box 200 and the buffer structure 100 are firmly combined at multiple angles and positions, which can enhance the connection strength between the corrugated cardboard box 200 and the buffer structure 100, which is beneficial to enhancing the overall structural stability of the base pad assembly 10 and improving the pressure resistance and impact resistance of the base pad assembly 10.

[0157] For example, the number of first sub-boards 221a is one, the number of first flanges 230 is at least one, and the first sub-boards 221a are connected to at least one first flange 230.

[0158] For example, there are multiple first sub-boards 221a and first flanges 230, and each first sub-board 221a is connected to at least one first flange 230.

[0159] For example, there is one second sub-board 221b and at least one second flange 240, and the second sub-board 221b is connected to at least one second flange 240.

[0160] For example, there are multiple second sub-boards 221b and second flanges 240, and each second sub-board 221b is connected to at least one second flange 240.

[0161] According to some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the base pad assembly 10 also includes paper corner protectors 300, which surround the buffer structure 100. The side plate 220 and the bottom plate 210 both abut against the buffer structure 100 through the paper corner protectors 300.

[0162] Specifically, the base pad assembly 10 also includes paper corner protectors 300, which surround the cushioning structure 100. That is, a portion of the paper corner protectors 300 is located between the cushioning structure 100 and the side plate 220, and another portion of the paper corner protectors 300 is located between the cushioning structure 100 and the base plate 210. The paper corner protectors 300 are connected to the cushioning structure 100, the side plate 220 abuts against the cushioning structure 100 via the paper corner protectors 300, and the base plate 210 abuts against the cushioning structure 100 via the paper corner protectors 300.

[0163] Understandably, the paper corner protector 300 has a ring-shaped structure. The paper corner protector 300 can enhance the anti-collision capability at the corner 136 of the base pad assembly 10. In this way, when the base pad assembly 10 is tied with straps, it is beneficial to reduce the deformation of the base pad assembly 10, ensure the size of the base pad assembly 10, and effectively support the packaged item.

[0164] Understandably, the paper corner protectors 300 serve to reinforce the edges and corners. They possess a certain degree of rigidity, support, compressive strength, and cushioning, connecting the cushioning structure 100 and the corrugated cardboard box 200, thus enhancing the overall structural stability. By providing the paper corner protectors 300, a stable and flat contact surface is created for the side panels 220 and the bottom panel 210, allowing them to be securely assembled to the cushioning structure 100 indirectly through the paper corner protectors 300. The paper corner protectors 300 also ensure a more uniform and tighter contact between the side panels 220 and the cushioning structure 100, reducing local gaps.

[0165] Understandably, the corner 136 of the cushioning structure 100 is a stress concentration point and is prone to damage, especially during transportation, where it is easily subjected to squeezing, collision, or friction. Since the paper corner protectors 300 are arranged around the cushioning structure 100, they can cover the weakest areas of the cushioning structure 100, thus providing reinforcement and support. Furthermore, because the paper corner protectors 300 are located between the cushioning structure 100 and the side panel 220, they can share some of the pressure, reducing the localized stress on the corrugated cardboard box 200 and lowering the probability of the corrugated cardboard box 200 bending or even denting.

[0166] According to some embodiments of the present invention, such as Figure 8As shown, the paper corner protector 300 includes: a bottom corner protector 310, which is located between the buffer structure 100 and the base plate 210, and has an opening 312 in the middle; and a side corner protector 320, which is connected to the outer edge of the bottom corner protector 310, and is located between the buffer structure 100 and the side plate 220. The side corner protector 320 is arranged around the buffer structure 100, and along the direction from the base plate 210 to the buffer structure 100, the height of the side corner protector 320 is less than the height of the buffer structure 100.

[0167] Specifically, the structure of the paper corner protector 300 is refined.

[0168] The paper corner protector 300 includes a bottom corner protector 310 and a side corner protector 320. The side corner protector 320 is connected to the outer edge of the bottom corner protector 310. The bottom corner protector 310 is located between the cushioning structure 100 and the base plate 210, and the side corner protector 320 is located between the cushioning structure 100 and the side plate 220, and the side corner protector 320 is arranged around the cushioning structure 100.

[0169] The bottom corner protector 310 has an opening 312 in the middle, which enhances the anti-collision capability at the corner 136 of the bottom pad assembly 10 while reducing the material input of the bottom corner protector 310, thus helping to reduce the production cost of the product.

[0170] Along the direction from the base plate 210 to the buffer structure 100, the height of the side guard 320 is less than the height of the buffer structure 100. That is, the relationship between the height of the side guard 320 and the height of the buffer structure 100 is defined. In other words, the side guard 320 is located lower on the buffer structure 100. The lower part of the buffer structure 100 is a location of concentrated stress and vulnerability; therefore, by setting the position of the side guard 320, while ensuring the effectiveness of the paper corner protector 300 in reinforcing the edges and corners, the material input for the side guard 320 can be reduced, which helps to lower the production cost of the base pad assembly 10. In addition, the position of the side guard 320 can also prevent the paper corner protector 300 from interfering with the packaged item, which helps to reduce the assembly difficulty of the packaged item and the base pad assembly 10 and improve assembly efficiency.

[0171] According to some embodiments of the present invention, the buffer structure 100 is a honeycomb paper structure; or the buffer structure 100 is a vertical corrugated paper structure; or a part of the buffer structure 100 is a honeycomb paper structure and the other part of the buffer structure 100 is a vertical corrugated paper structure.

[0172] Specifically, the structure of the buffer device is refined.

[0173] The cushioning structure 100 is a honeycomb paper structure. Alternatively, the cushioning structure 100 is a vertical corrugated paper structure. Or, a portion of the cushioning structure 100 is a honeycomb paper structure, and the other portion is a vertical corrugated paper structure.

[0174] Honeycomb paper structures have excellent cushioning performance, high strength and rigidity per unit weight, which is conducive to recovery of deformation after compression, has good resilience, and is not prone to failure.

[0175] Vertical corrugated paper structures have good cushioning capabilities, effectively reducing shock and dispersing stress, and can effectively resist pressure from above and below, with strong load-bearing capacity.

[0176] According to some embodiments of the present invention, such as Figure 1 As shown, the buffer structure 100 is provided with a limiting part 120 on one side of the supporting part 110. The limiting part 120 is arranged separately from the supporting part 110 and is used to limit the packaged item. In the direction from the bottom plate 210 to the buffer structure 100, the height of the limiting part 120 away from the bottom plate 210 is lower than the height of the supporting part 110 away from the bottom plate 210.

[0177] Specifically, the buffer structure 100 is also provided with a limiting part 120, and the limiting part 120 and the supporting part 110 are located on the same side of the buffer structure 100.

[0178] The limiting part 120 and the supporting part 110 are arranged separately, that is, there is no interference between the limiting part 120 and the supporting part 110. When the packaged item is placed on the base pad assembly 10, the limiting part 120 is used to limit the packaged item to restrict the displacement of the packaged item relative to the base pad assembly 10. This can prevent the packaged item from moving, shaking, or deflecting, and can ensure the effective fit between the packaged item and the supporting part 110, thus ensuring the effectiveness and reliability of the base pad assembly 10 in supporting the packaged item.

[0179] In the direction from the base plate 210 to the buffer structure 100, the height of the side of the limiting part 120 facing away from the base plate 210 is lower than the height of the side of the supporting part 110 facing away from the base plate 210. That is, the distance from the side of the limiting part 120 facing away from the base plate 210 to the base plate 210 is less than the distance from the side of the supporting part 110 facing away from the base plate 210 to the base plate 210. The supporting part 110 is used to support the packaged item. When the packaged item is placed on the base pad assembly 10, the limiting part will not interfere with the assembly of the packaged item and the supporting part 110. That is, the limiting part 120 will not push the packaged item upwards, ensuring that the packaged item effectively rests on the supporting part 110, ensuring the contact area between the packaged item and the first flange 230, preventing the packaged item from tilting, and ensuring that the supporting part 110 can provide a stable load-bearing foundation.

[0180] According to some embodiments of the present invention, the limiting part 120 includes at least one of the limiting groove 122 and the limiting hole 124.

[0181] Specifically, the structure of the limiting part 120 is refined.

[0182] The limiting portion 120 includes at least one of a limiting groove 122 and a limiting hole 124. That is, the limiting portion 120 includes a limiting groove 122, or the limiting portion 120 includes a limiting hole 124, or the limiting portion 120 includes both a limiting groove 122 and a limiting hole 124.

[0183] After the packaged item is placed on the base assembly 10, the positioning part 510 of the packaged item will insert into the limiting part 120. For example, the positioning part 510 will insert into the limiting hole 124, or the positioning part 510 will insert into the limiting groove 122. The structure of the limiting part 120 can increase the limiting area of ​​the limiting part 120 and the packaged item, and can limit the packaged item from multiple directions and multiple positions, effectively preventing the packaged item from moving, shaking, and deflecting.

[0184] For example, the number of limiting parts 120 is one.

[0185] For example, there are multiple limiting parts 120, which are arranged at intervals. The multiple limiting parts 120 have the same structure. Or, some of the multiple limiting parts 120 have the same structure. Or, the multiple limiting parts 120 have different structures.

[0186] According to some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the buffer structure 100 includes: a buffer body 130, which is located between the support portion 110 and the base plate 210; when the limiting portion 120 includes a limiting groove 122, the limiting portion 120 includes a first protrusion 126 and a second protrusion 128, both of which are connected to the side of the buffer body 130 away from the base plate 210, and the first protrusion 126 and the second protrusion 128 are arranged at intervals to enclose the limiting groove 122; when the limiting portion 120 includes a limiting hole 124, the limiting hole 124 is provided in the buffer body 130.

[0187] Specifically, the buffer structure 100 includes a buffer body 130, which is located between the support part 110 and the base plate 210, and the support part 110 is connected to the buffer body 130.

[0188] When the limiting part 120 includes a limiting groove 122, the limiting part 120 includes a first protrusion 126 and a second protrusion 128, both of which are connected to the side of the buffer body 130 away from the bottom plate 210. That is, the first protrusion 126, the second protrusion 128, and the support part 110 are located on the same side of the buffer body 130, and any one of the first protrusion 126, the second protrusion 128, and the support part 110 is connected to the buffer body 130. The first protrusion 126 and the second protrusion 128 are arranged at intervals to enclose the limiting groove 122. The positioning part 510 of the packaged item will extend between the first protrusion 126 and the second protrusion 128 to limit the packaged item from multiple directions and angles, effectively preventing the packaged item from moving, shaking, and deflecting.

[0189] When the limiting part 120 includes the limiting hole 124, the limiting hole 124 is provided in the buffer body 130, and the positioning part 510 of the packaged item will extend into the limiting hole 124 to limit the packaged item from multiple directions and multiple angles, which can effectively prevent the packaged item from moving, shaking and deflecting.

[0190] For example, the number of limiting grooves 122 is one.

[0191] For example, there are multiple limiting grooves 122, which are arranged at intervals to increase the limiting area of ​​the limiting part 120 and the packaged item. This allows the packaged item to be limited from multiple directions and positions, effectively preventing the packaged item from moving, shaking, or deflecting.

[0192] For example, the number of limiting holes 124 is one.

[0193] For example, there are multiple limiting holes 124, which are arranged at intervals to increase the limiting area of ​​the limiting part 120 and the packaged item. This allows the packaged item to be limited from multiple directions and positions, effectively preventing the packaged item from moving, shaking, or deflecting.

[0194] According to some embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 15 , Figure 16 and Figure 17 As shown, there are multiple limiting holes 124, and the multiple limiting holes 124 include at least a first limiting hole 124a and a second limiting hole 124b; when the limiting part 120 includes a limiting groove 122 and a first limiting hole 124a, the first limiting hole 124a is located between the first protrusion 126 and the second protrusion 128; when the limiting part 120 includes a limiting groove 122 and a second limiting hole 124b, the second limiting hole 124b is arranged separately from the limiting groove 122.

[0195] Specifically, there are multiple limiting holes 124, which are categorized into different types. Each limiting hole 124 includes at least a first limiting hole 124a and a second limiting hole 124b. The first limiting hole 124a and the second limiting hole 124b are located in different positions.

[0196] When the limiting part 120 includes a limiting groove 122 and a first limiting hole 124a, the first limiting hole 124a is located between the first protrusion 126 and the second protrusion 128. That is, it defines the positional relationship between the limiting groove 122 and the first limiting hole 124a. The positioning part 510 of the packaged item can extend into the first limiting hole 124a when it extends into the limiting groove 122, so as to increase the limiting area of ​​the positioning part 510 and the limiting part 120, and effectively prevent the packaged item from moving, shaking and deflecting.

[0197] When the limiting part 120 includes a limiting groove 122 and a second limiting hole 124b, the second limiting hole 124b is arranged separately from the limiting groove 122. That is, the positional relationship between the limiting groove 122 and the second limiting hole 124b is defined. The limiting groove 122 and the second limiting hole 124b can be limited and engaged with different positioning parts 510 of the packaged item. Through multiple positions and multiple limiting engagement structures, the displacement of the packaged item relative to the base pad assembly 10 is jointly restricted, providing structural support for effectively preventing the packaged item from moving, shaking and deflecting.

[0198] For example, when there are multiple first limiting holes 124a and limiting grooves 122, each first limiting hole 124a cooperates with one limiting groove 122.

[0199] For example, the number of second limiting holes 124b is at least one. When there are multiple second limiting holes 124b, the multiple second limiting holes 124b are arranged at intervals.

[0200] According to some embodiments of the present invention, such as Figure 2 , Figure 7 and Figure 8 As shown, the buffer body 130 includes: a first buffer portion 131; a second buffer portion 132, wherein the first buffer portion 131 is located between the support portion 110 and the second buffer portion 132; when the limiting portion 120 includes a first protrusion 126 and a second protrusion 128, the first protrusion 126, the second protrusion 128 and the support portion 110 are located on the same side of the first buffer portion 131; when the limiting portion 120 includes a limiting hole 124, the limiting hole 124 penetrates the first buffer portion 131.

[0201] Specifically, the buffer body 130 includes a first buffer portion 131 and a second buffer portion 132. The first buffer portion 131 is located between the support portion 110 and the second buffer portion 132, that is, it defines the positional relationship between the first buffer portion 131, the second buffer portion 132 and the support portion 110.

[0202] The first buffer part 131 and the second buffer part 132 cooperate to ensure the thickness of the buffer structure 100 in the direction from the base plate 210 to the buffer structure 100, so as to ensure the positional relationship between the support part 110 and the packaged item, and so that the support part 110 can effectively support the packaged item.

[0203] When the limiting part 120 includes a first protrusion 126 and a second protrusion 128, the first protrusion 126, the second protrusion 128 and the support part 110 are located on the same side of the first buffer part 131. The first buffer part 131 serves as a mounting carrier for the first protrusion 126, the second protrusion 128 and the support part 110, and has the function of mounting and fixing the first protrusion 126, the second protrusion 128 and the support part 110.

[0204] When the limiting part 120 includes a limiting hole 124, the limiting hole 124 penetrates the first buffer part 131, that is, the limiting hole 124 penetrates the first buffer part 131, but the limiting part 120 does not penetrate the second buffer part 132. In this way, not only can the insertion and engagement requirements of the positioning part 510 of the packaged item and the limiting hole 124 be met, but the volume of the limiting hole 124 can also be reduced, the area of ​​the buffer body 130 where the limiting hole 124 is set can be reduced, the structural strength and rigidity of the buffer body 130 can be guaranteed, and the buffering effect of the buffer body 130 can be guaranteed.

[0205] According to some embodiments of the present invention, such as Figure 2 , Figure 7 and Figure 8 As shown, the first buffer portion 131 includes: a first buffer layer 133, in which the second limiting hole 124b penetrates the first buffer layer 133 when the limiting portion 120 includes the second limiting hole 124b; a second buffer layer 134, in which the first buffer layer 133 is located between the support portion 110 and the second buffer layer 134, and the first buffer portion 131 is cross-sectioned along a direction perpendicular to the bottom plate 210 to the first flange 230, the cross-sectional area of ​​the second buffer layer 134 is larger than the cross-sectional area of ​​the first buffer layer 133, and a portion of the second buffer layer 134 protrudes from the outer peripheral wall of the first buffer layer 133; in which the limiting portion 120 includes the first protrusion 126 and the second protrusion 128, the first protrusion 126 and the second protrusion 128 are both located on the portion of the second buffer layer 134 that protrudes from the first buffer layer 133; in which the limiting portion 120 includes the first limiting hole 124a, the first limiting hole 124a penetrates the second buffer layer 134.

[0206] Specifically, the first buffer section 131 includes a first buffer layer 133 and a second buffer layer 134.

[0207] The first buffer layer 133 is located between the support portion 110 and the second buffer layer 134.

[0208] The bottom pad assembly 10 is cross-sectioned along a direction perpendicular to the first buffer layer 133 to the second buffer layer 134. The cross-sectional area of ​​the second buffer layer 134 is larger than that of the first buffer layer 133. A portion of the second buffer layer 134 protrudes from the outer peripheral wall of the first buffer layer 133.

[0209] When the limiting part 120 includes the second limiting hole 124b, the second limiting hole 124b penetrates the first buffer layer 133, but does not penetrate the second buffer layer 134. In this way, not only can the insertion and engagement requirements of the positioning part 510 of the packaged item and the second limiting hole 124b be met, but the volume of the second limiting hole 124b can also be reduced, the area where the second limiting hole 124b is set in the first buffer part 131 can be reduced, the structural strength and rigidity of the buffer body 130 can be guaranteed, and the buffering effect of the buffer body 130 can be guaranteed.

[0210] When the limiting part 120 includes a first protrusion 126 and a second protrusion 128, both the first protrusion 126 and the second protrusion 128 are located on the portion of the second buffer layer 134 that protrudes beyond the first buffer layer 133. That is, the portion of the second buffer layer 134 that protrudes beyond the first buffer layer 133 serves as a mounting carrier for the first protrusion 126 and the second protrusion 128, and has the function of installing and fixing the first protrusion 126 and the second protrusion 128. It can be understood that by utilizing the difference in area between the first buffer layer 133 and the second buffer layer 134, the first protrusion 126 and the second protrusion 128 are positioned on the second buffer layer 134, and the first buffer layer 133 avoids the first protrusion 126 and the second protrusion 128, which can meet the usage requirements of the positioning part 510 of the packaged item and the limiting groove 122 for insertion and engagement. It is understandable that the portion of the second buffer layer 134 protruding beyond the first buffer layer 133 and forming a recessed platform with the first buffer layer 133 will reduce the installation height of the first protrusion 126 and the second protrusion 128. This results in the height of the side of the limiting part 120 away from the base plate 210 along the direction from the base plate 210 to the buffer structure 100 being lower than the height of the side of the supporting part 110 away from the base plate 210. Therefore, by setting the cooperative structure of the first buffer layer 133 and the second buffer layer 134, the effectiveness of the limiting groove 122 can be ensured while reducing the material input of the first buffer part 131, which is beneficial to reducing the production cost of the base pad assembly 10.

[0211] When the limiting part 120 includes a first limiting hole 124a, the first limiting hole 124a penetrates the second buffer layer 134. The portion of the second buffer layer 134 protruding outside the first buffer layer 133 is not blocked by the first buffer layer 133, and the portion of the second buffer layer 134 protruding outside the first buffer layer 133 is exposed outside the first buffer layer 133. By allowing the first limiting hole 124a to penetrate the second buffer layer 134, the first buffer layer 133 will not block the first limiting hole 124a, thus satisfying the usage requirements of the positioning part 510 of the packaged item and the insertion and engagement of the first limiting hole 124a. Therefore, by setting the engagement structure of the first buffer layer 133 and the second buffer layer 134, while ensuring the effectiveness of the setting of the first limiting hole 124a, the material input of the first buffer part 131 can be reduced, which is beneficial to reducing the production cost of the base pad assembly 10.

[0212] According to some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 7 As shown, at least a portion of the corners 136 of the first buffer layer 133 are provided with notches 137, and the second limiting hole 124b is disposed opposite to the notches 137.

[0213] Specifically, the structure of the first buffer layer 133 is refined.

[0214] Along the circumference of the buffer structure 100, the sidewall of the first buffer layer 133 includes a plurality of sub-walls connected end to end. Any two adjacent sub-walls extend in different directions, and the connection point of two adjacent sub-walls is the corner 136 of the first buffer layer 133.

[0215] The first buffer layer 133 has multiple corners 136, and at least a portion of the multiple corners 136 are provided with notches 137. The notches 137 are used to avoid the bottom structural components (such as hinges) of the item to be packaged, so as to avoid interference with the structural components of the item to be packaged. The structure of the notches 137 can not only avoid the structural components of the item to be packaged, but also does not increase the thickness of the bottom pad assembly 10.

[0216] The second limiting hole 124b is disposed opposite to the notch 137. The position of the second limiting hole 124b matches the position of the positioning part 510 of the part to be packaged, and the position of the notch 137 matches the position of the structural part of the part to be packaged.

[0217] In some other embodiments, the location of the notch 137 is not limited to the corner 136 of the first buffer layer 133, but the notch 137 can also be located in the portion of the first buffer layer 133 between two adjacent corners 136.

[0218] In some other embodiments, the second limiting hole 124b may not be positioned opposite to the notch 137.

[0219] According to some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the second buffer section 132 includes a plurality of third buffer layers 135, which are stacked together.

[0220] Specifically, the structure of the second buffer section 132 is refined. The second buffer section 132 includes multiple third buffer layers 135, which are stacked. Each third buffer layer 135 has good elasticity, compressibility, and resilience. When multiple third buffer layers 135 are stacked together, they can form a multi-layered energy absorption path. When an external impact force acts on the base pad assembly 10, the different third buffer layers 135 respond sequentially, and the multiple third buffer layers 135 are gradually compressed, thereby delaying the transmission of impact and dispersing the impact energy. The impact will not be concentrated in a certain third buffer layer 135 or a certain point in the second buffer section 132, which is beneficial to improving the buffering performance of the buffer structure 100, realizing the rapid absorption of impact energy, and realizing the effective dispersion of energy.

[0221] In addition, multiple third buffer layers 135 can more effectively absorb and mitigate the impact from the outside compared to a single third buffer layer. By setting them in layers, the impact will not be concentrated on a single third buffer layer 135, but will be shared by multiple third buffer layers 135. This can effectively reduce the risk of local crushing and deformation, and effectively protect the packaged items.

[0222] A packaging box according to some embodiments of this application includes: a base pad assembly 10 as described in any of the above embodiments.

[0223] The packaging box provided in this application includes the bottom pad assembly 10 as described in the above embodiment, and therefore has all the beneficial effects of the bottom pad assembly 10, which will not be described in detail here.

[0224] For example, the packaging box also includes a side panel and a top panel, the top panel being spaced apart from the bottom pad assembly 10, and the side panel being connected between the top panel and the bottom pad assembly 10.

[0225] The packaging box covers the outside of the item to be packaged.

[0226] like Figure 12 , Figure 13 , Figure 14 and Figure 15As shown, a household appliance assembly 50 according to some embodiments of this application includes: a household appliance 500; and a base pad assembly 10 of any of the above embodiments; or a packaging box as described in the above embodiments, the packaging box covering the household appliance 500; the household appliance 500 is located on the base pad assembly 10, a first flange 230 is located between the household appliance 500 and the support portion 110, and at least a portion of the positioning portion 510 of the household appliance 500 is detachably inserted into the limiting portion 120 of the base pad assembly 10.

[0227] The household appliance assembly 50 provided in this application includes the base pad assembly 10 as described in any of the above embodiments or the packaging box as described in the above embodiments. Therefore, it has all the beneficial effects of the base pad assembly 10, which will not be described in detail here.

[0228] For example, the category of household appliances 500 includes refrigeration appliances, washing appliances, and other small appliances, which will not be listed here. For instance, refrigeration appliances include refrigerators, freezers, air conditioners, etc. Washing appliances include washing machines, dryers, and washer-dryer combos, etc. Small appliances include dishwashers, sterilizers, etc.

[0229] Exemplarily, the bottom pad assembly 10 of this application includes a cushioning structure 100, a corrugated cardboard box 200, and paper corner protectors 300. The corrugated cardboard box 200 is provided with a first flange 230 and a second flange 240. The bottom of the bottom pad assembly 10 uses paper corner protectors 300 to enhance the corner impact resistance. The corrugated cardboard box 200 has a cushioning structure 100 inside, which simplifies the assembly structure of the bottom pad assembly 10 and can improve the pressure-bearing capacity and overall strength of the bottom pad assembly 10, making it convenient for the household appliance 500 to be picked up, placed, and positioned, and improving the stability and safety of the packaging.

[0230] For example, after the cushioning structure 100 is placed in the corrugated cardboard box 200, the first flange 230 and the second flange 240 around the corrugated cardboard box 200 are bent at 90° along the pressure line 400. The first flange 230 is bonded to the support portion 110 of the cushioning structure 100, and the second flange 240 is bonded to the portion of the cushioning structure 100 located around the support portion 110, which can improve the pressure bearing capacity of the bottom pad assembly 10.

[0231] For example, the cushioning structure 100 is a honeycomb paper structure. The cushioning structure 100 is processed using a die-cutting process, and the various components of the cushioning structure 100 are glued together. This, along with the first flange 230 and the second flange 240 of the corrugated cardboard box 200, increases the overall integrity and impact resistance of the packaging.

[0232] For example, the buffer structure 100 includes a plurality of honeycomb pads 1 (i.e., first protrusions 126 and second protrusions 128), a plurality of honeycomb pads 2 (i.e., support portions 110), honeycomb pads 3 (i.e., support portions 110), honeycomb pads 4 (i.e., support portions 110), honeycomb pads 5 (i.e., first buffer layer 133), honeycomb pads 6 (i.e., second buffer layer 134), a plurality of honeycomb pads 7 (i.e., third buffer layer 135), and paper corner protectors 300. The first protrusions 126, second protrusions 128, support portions 110, first buffer layer 133, second buffer layer 134, and third buffer layer 135 are bonded together.

[0233] For example, such as Figure 9 As shown, after the four sides of the unfolded corrugated cardboard box 200 are folded up along the crease 400, the tongues 223a of the left and right sub-plates 221 are inserted into the bent portions 223b of the front and rear sub-plates 221 to form a cavity structure.

[0234] For example, Figure 3 and Figure 4 As shown, after the cushioning structure 100 is placed inside the corrugated cardboard box 200, the first flange 230 and the second flange 240 are folded along the pressure line 400, and the first flange and the support part 110 are bonded together, and the second flange 240 is bonded to the part of the cushioning structure 100 located around the support part 110.

[0235] For example, when it is necessary to package a household appliance 500, the base pad assembly 10 is first placed directly in a position, and then the positioning part 510 of the household appliance 500 is aligned with the limiting part 120 and placed to complete the packaging operation.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
