Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, and in particular relates to an inner lining structure and a packaging box. Background Technology

[0002] Panel lights are lighting devices suitable for recessed installation in ceilings to achieve direct lighting. Their light-emitting surface usually uses a light guide plate with high light transmittance, which allows light to diffuse evenly when passing through, thus forming a soft and consistent planar light source with good illuminance uniformity. The lighting effect is comfortable and bright, which helps to reduce visual fatigue.

[0003] As market demand for panel lights continues to grow, their slim and lightweight design has become a major feature, but this also makes them unsuitable for vertical display and arrangement. To prevent damage during transportation and display, existing packaging boxes typically use linings made of materials such as pearl cotton, EVA, or sponge to provide a cushioning structure for the panel lights, thereby protecting their internal structure.

[0004] However, linings made of pearl cotton, EVA, or sponge are not only expensive, but also do not meet increasingly stringent environmental requirements for panel lights. Especially as the packaging industry gradually requires "de-plasticization," these materials are difficult to meet the development trend of green packaging. Utility Model Content

[0005] The purpose of this application is to provide an inner lining structure that addresses the issue of how to improve the reliability and environmental friendliness of panel light packaging.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] In a first aspect, a lining structure is provided, comprising: a base plate, two first side plate assemblies disposed opposite to each other and connected to the base plate, and two second side plate assemblies disposed opposite to each other and connected to the base plate, wherein the first side plate assemblies and the second side plate assemblies are arranged alternately in sequence, and both ends of any first side plate assembly are respectively connected to two second side plate assemblies, wherein the base plate, the two first side plate assemblies and the two second side plate assemblies together form a receiving cavity, wherein the first side plate assembly has a hollow structure, and the lining structure further comprises a buffer platform located at least partially within the receiving cavity and having a hollow structure, wherein each first side plate assembly is provided with at least one buffer platform.

[0008] In some embodiments, the first side plate assembly includes a first side plate connected to the base plate, a second side plate spaced apart from the first side plate and at least partially located in the receiving cavity, and a third side plate connecting the first side plate and the second side plate, wherein the buffer platform is connected to the second side plate.

[0009] In some embodiments, the buffer platform includes an inner support platform and an outer support platform. The inner support platform is connected to the first side plate and the bottom plate and protrudes into the accommodating cavity. The outer support platform is connected to the second side plate and protrudes into the accommodating cavity and is stacked with the outer support platform.

[0010] In some embodiments, the inner support platform includes two interconnected and staggered inner support plates, which are respectively connected to the first side plate and the bottom plate, and are stacked with the outer support platform.

[0011] In some embodiments, the outer support platform includes two interconnected and staggered outer support plates, the two outer support plates being respectively connected to the second side plate and the bottom plate.

[0012] In some embodiments, the first side plate assembly further includes a third side plate located in the accommodating cavity and laid flat on the bottom plate, and a fourth side plate disposed on the bottom plate, wherein the outer support plate is connected to the fourth side plate.

[0013] In some embodiments, the second side panel assembly includes a pressure strip connecting the fourth and fifth side panels of the base plate and connecting the edges of the fourth and fifth side panels, the pressure strip having a hollow structure and extending at least partially into the receiving cavity.

[0014] In some embodiments, the first side panel assembly has a slot, and the edge of the pressure strip has a protruding tongue that engages with the slot.

[0015] In some embodiments, the pressure strip includes a plurality of fifth side plates and sixth side plates connected in sequence, wherein one of the fifth side plates and the sixth side plate is connected to the fourth side plate and the fifth side plate.

[0016] Secondly, a packaging box is provided, which includes the aforementioned inner lining structure.

[0017] The beneficial effects of this application are as follows: A receiving cavity is formed by the base plate, the first side plate assembly, and the second side plate assembly. Utilizing the hollow structure of the first side plate assembly and the buffer platform, the first side plate assembly can absorb the energy of accidental impacts to the panel light along the second direction, while the buffer platform can absorb the energy of accidental impacts to the panel light along the direction perpendicular to the base plate. This improves the reliability of the inner lining structure in protecting the panel light packaging, effectively absorbing the impact forces that may occur during transportation and providing stable protection for the panel light. Simultaneously, the base plate, each of the first side plates, each of the second side plates, and the buffer platform are integrally formed from paper material, meeting environmental protection requirements and conforming to the trend of green packaging. Furthermore, the integrally formed structure is simple, easy to process, and reduces production costs. Attached Figure Description

[0028] Please see Figures 1 to 2 This application provides an inner lining structure 100 and a packaging box having the same. The inner lining structure 100 can position and protect the packaged items, thereby improving the safety and reliability of the items. In this embodiment, the item can be a panel light; in other embodiments, the item can be selected according to the actual situation, and no limitation is made here.

[0029] Please see Figures 1 to 2 The inner lining structure 100 includes: a base plate 40, two first side plate assemblies 10 that are arranged opposite to each other and connected to the base plate 40, and two second side plate assemblies 20 that are arranged opposite to each other and connected to the base plate 40. It can be understood that the base plate 40, the first side plate assemblies 10 and the second side plate assemblies 20 can all be made of paper, so that the inner lining structure 100 has a certain strength and flexibility, and can effectively support and protect the panel light.

[0030] Two first side plates 11 are arranged along a first direction, which can be represented as the X direction, and two second side plates 12 are arranged along a second direction, which can be represented as the Y direction.

[0031] Please see Figures 1 to 2 The first side panel assembly 10 and the second side panel assembly 20 are arranged alternately in sequence, and the two ends of any first side panel assembly 10 are respectively connected to the two second side panel assemblies 20. The first side panel assembly 10 and the second side panel assembly 20 have a certain height, so that the base plate 40, the two first side panel assemblies 10 and the two second side panel assemblies 20 together form a receiving cavity 111. The receiving cavity 111 has an opening, and the panel light can be put into the receiving cavity 111 from the opening. The two ends of the panel light are respectively adjacent to the two first side panel assemblies 10 along the first direction.

[0032] The first side panel assembly 10 has a hollow structure and a certain degree of elasticity. When the panel light located in the accommodating cavity 111 is subjected to an accidental impact, the panel light will abut against the first side panel assembly 10 in the second direction, so that the two first side panel assemblies 10 can undergo elastic deformation, thereby absorbing the impact energy of the panel light and improving the safety of the panel light protection.

[0033] Please see Figures 1 to 2 The inner lining structure 100 also includes a buffer platform 30, which is at least partially located within the accommodating cavity 111, has a hollow structure, and possesses elastic restoring force. Each first side panel assembly 10 is provided with at least one buffer platform 30. In this embodiment, each first side panel assembly 10 is provided with two buffer platforms 30 spaced apart along a first direction. In other embodiments, the number of buffer platforms 30 can be selected according to actual conditions, and is not limited here. The edge of the panel light abuts against four buffer platforms 30, so that when the panel light suffers an accidental impact in the direction perpendicular to the base plate 40, the panel light can drive each buffer platform 30 to undergo elastic deformation, thereby allowing the buffer platforms 30 to absorb the accidental impact suffered by the panel light and improving the reliability of the panel light protection. The base plate 40, each first side plate 11, each second side plate 12, and the buffer platform 30 are integrally formed from paper material. It can be understood that the base plate 40, each first side plate 11, each second side plate 12, and the buffer platform 30 can be integrally formed from a single sheet of folded paper. This not only simplifies the processing of the inner lining structure 100, but also makes the inner lining structure 100, which is made of paper material, easy to decompose, thereby improving the environmental friendliness of the inner lining structure 100 and reducing costs.

[0034] Please see Figures 1 to 2 The inner lining structure 100 provided in this application embodiment is made of paper, and can be folded from a single piece of cardboard to form a base plate 40, a first side plate assembly 10, and a second-level side plate assembly, which meets environmental protection requirements.

[0035] Please see Figures 1 to 2 The inner lining structure 100 provided in this embodiment forms an accommodating cavity 111 through a base plate 40, a first side plate assembly 10, and a second side plate assembly 20. Utilizing the hollow structure of the first side plate assembly 10 and the buffer platform 30, the first side plate assembly 10 can absorb the energy of accidental impacts to the panel light along a second direction, while the buffer platform 30 can absorb the energy of accidental impacts to the panel light along a direction perpendicular to the base plate 40. This improves the reliability of the inner lining structure 100 in protecting the panel light packaging, effectively absorbing impact forces that may occur during transportation and providing stable protection for the panel light. Simultaneously, the base plate 40, each first side plate 11, each second side plate 12, and the buffer platform 30 are integrally formed from paper material, meeting environmental protection requirements and conforming to the trend of green packaging. Furthermore, the integrally formed structure is simple, easy to process, and reduces production costs.

[0036] Optionally, the base plate 40, the first side plate assembly 10, the buffer platform 30, and the second side plate assembly 20 can be made of corrugated paper. Corrugated paper is a composite material made by sandwiching core paper between two or more layers of flat cardboard (called face paper). The core paper is processed into a wavy (corrugated) shape through a special process to form a hollow structure. Corrugated paper is widely used in the packaging field due to its lightweight, high strength, impact resistance, and good cushioning performance, and is suitable for making packaging boxes and inner lining structures 100. Its main characteristics include environmental friendliness and recyclability, low cost, ease of processing and printing, and the ability to flexibly adjust strength and thickness through different corrugation types to meet various packaging needs.

[0037] Please see Figures 1 to 2 In some embodiments, the first side plate assembly 10 includes a first side plate 11 connected to the base plate 40, a second side plate 12 spaced apart from the first side plate 11 and at least partially located in the receiving cavity 111, and a third side plate 13 connecting the first side plate 11 and the second side plate 12, with the buffer platform 30 connected to the second side plate 12.

[0038] It is understood that the edge of the first side plate 11 is connected to the edge of the base plate 40 along the first direction, and the height directions of the first side plate 11 and the second side plate 12 are both arranged in a direction perpendicular to the base plate 40. The third side plate 13 is arranged in a direction parallel to the base plate 40, so that the two sides of the third side plate 13 are respectively connected to the first side plate 11 and the second side plate 12. The spaced arrangement of the first side plate 11 and the second side plate 12 provides deformation space for the elastic deformation of the first side plate assembly 10.

[0039] Optionally, the first side panel 11, the second side panel 12, and the third side panel 13 form a multi-layered buffer structure, enhancing the impact resistance of the inner lining structure 100 to the panel light. Furthermore, the spatial arrangement of the first side panel 11, the second side panel 12, and the third side panel 13 can be achieved through the folding of paper materials, maintaining environmental friendliness. Simultaneously, the dual support of the first side panel 11 and the second side panel 12 improves the overall rigidity and stability of the inner lining structure 100, ensuring the safety of the panel light during transportation and display.

[0040] Please see Figures 1 to 2 In some embodiments, the buffer platform 30 includes an inner support platform 31 and an outer support platform 32. The inner support platform 31 is connected to the first side plate 11 and the bottom plate 40 and protrudes into the receiving cavity 111. The outer support platform 32 is connected to the second side plate 12 and protrudes into the receiving cavity 111 and is stacked with the outer support platform 32.

[0041] Optionally, both the inner support platform 31 and the outer support platform 32 are L-shaped. The two ends of the inner support platform 31 are connected to the first side plate 11 and the bottom plate 40, respectively, and the two ends of the outer support platform 32 are connected to the second side plate 12 and the bottom plate 40, respectively. The panel light is placed against and rests on the outer support platform 32. The inner support platform 31 and the outer support platform 32 protrude from the accommodating cavity 111 in a stacked arrangement, thereby improving the structural strength and buffering performance of the buffer platform 30. This can effectively disperse the external impact of the panel light and enhance the protection capability of the inner lining structure 100 for the panel light. At the same time, the folding characteristics of paper materials are used to achieve structural simplification and environmental protection, meeting the requirements of green packaging.

[0042] Please see Figures 1 to 2 In some embodiments, the inner support platform 31 includes two interconnected and staggered inner support plates 311, which are respectively connected to the first side plate 11 and the bottom plate 40, and are stacked with the outer support platform 32.

[0043] Optionally, the inner support plate 311 connecting the first side plate 11 is arranged in a direction parallel to the bottom plate 40 and attached to the back of the inner support platform 31, and the other inner support plate 311 connecting the bottom plate 40 is arranged in a direction parallel to the first side plate 11 and attached to the back of the inner support platform 31. Thus, the buffering performance is achieved through the two staggered inner support plates 311, which improves the impact resistance of the inner lining structure 100, protects the panel light from external impact, and maintains the environmental advantages of paper materials. The structure is compact and easy to fold and form.

[0044] Please see Figures 1 to 2 In some embodiments, the outer support platform 32 includes two interconnected and staggered outer support plates 321, which are respectively connected to the second side plate 12 and the bottom plate 40.

[0045] Optionally, the outer support plate 321 connecting the second side plate 12 is arranged in a direction parallel to the bottom plate 40 and stacked with one of the inner support plates 311, and the other outer support plate 321 connecting the bottom plate 40 is arranged in a direction parallel to the second side plate 12 and stacked with another inner support plate 311. Thus, the buffering performance is achieved through the two staggered inner support plates 311, which improves the impact resistance of the inner lining structure 100, protects the panel light from external impact, and has a compact structure that is easy to fold and form.

[0046] The two inner support plates 311 are stacked with the two outer support plates 321 respectively, which enhances the overall rigidity and stability of the buffer platform 30, improves the protection effect of the inner lining on the panel light, and simplifies the processing technology and reduces the production cost by utilizing the folding characteristics of paper material, thus meeting the requirements of environmentally friendly packaging.

[0047] In some embodiments, the first side plate assembly 10 further includes a third side plate 13 located in the accommodating cavity 111 and laid flat on the bottom plate 40, and a fourth side plate 14 disposed on the bottom plate 40, with an outer support plate 321 connected to the fourth side plate.

[0048] Optionally, both fourth and third side plates are laid on the bottom plate 40, thereby improving the structural strength of the inner lining structure 100 at the bottom plate 40, strengthening the bottom support capacity of the inner lining structure 100, and enhancing the overall compressive strength.

[0049] Please see Figures 1 to 2 In some embodiments, the second side panel assembly 20 includes a pressure strip connecting the fourth side panel 14 and the fifth side panel 21 of the base plate 40 and connecting the edges of the fourth side panel 14 and the fifth side panel 21. The pressure strip has a hollow structure and extends at least partially into the receiving cavity 111.

[0050] It is understandable that the hollow pressure strip has a certain elastic deformation capability. The panel light is placed on each buffer platform 30, and the pressure strip is folded into the receiving cavity 111 so that the lower end of the pressure strip abuts against the upper surface of the panel light, so that the panel light is positioned between the four buffer platforms 30 and the two pressure strips in the direction perpendicular to the bottom plate 40.

[0051] Optionally, when the panel light suffers an accidental upward impact, the panel light can drive the two retaining strips to elastically deform, allowing the two retaining strips to absorb the accidental impact energy of the panel light and enhance the protective capability of the inner lining structure 100. It is also understood that the retaining strips, made of paper material with a hollow structure, not only maintain environmentally friendly characteristics but also improve the impact resistance of the inner lining structure 100 through structural optimization, making it suitable for the packaging needs of thin and light panel lights.

[0052] Please see Figures 1 to 2 In some embodiments, the first side panel assembly 10 has a slot 15, and the edge of the pressure strip has a protruding tongue 23, which is inserted into the slot 15.

[0053] Optionally, two slots 15 are arranged at intervals along the first direction on the two first side plates 11, and tongues 23 are protruding at both ends of the pressure strip along the second direction. After the pressure strip is packaged in place, the two tongues 23 on the pressure strip are respectively inserted into the corresponding two slots 15, so that the pressure strip is kept in contact with the panel light. This not only enables the assembly and protection of the panel light by the inner lining structure 100, but also improves the overall stability and deformation resistance of the inner lining structure 100.

[0054] Optionally, the card slot 15 is located partly on the second side plate 12 and partly on the third side plate 13.

[0055] Please see Figures 1 to 2In some embodiments, the pressure strip includes a plurality of fifth side plates 21 and sixth side plates 22 connected in sequence, wherein one fifth side plate 21 and the sixth side plate 22 are connected to the fourth side plate 14 and the fifth side plate 21.

[0056] Optionally, multiple fifth side plates 21 and sixth side plates 22 are connected in sequence, and the fifth side plates 21 and sixth side plates 22 located at the ends are connected to the fourth side plate 14 and the fifth side plate 21. The tongue 23 is connected to one of the fifth side plates 21 and the sixth side plate 22. The cross-sectional shape of the pressure strip is polygonal, so that the pressure strip forms a flexible and stable hollow structure, which enhances the buffering performance and lateral support capability of the second side plate assembly 20.

[0057] Please see Figures 2 to 5 The following section, based on the characteristics of the inner lining structure 100, explains how to form the inner lining structure 100 by folding a single sheet of paper:

[0058] Please see Figure 2 First, fold lines (represented by dashed lines) are embossed on the folded paper, and cutting lines (represented by solid lines) are processed on the folded paper. The material of the folded paper can be corrugated paper.

[0059] Please see Figure 3 Next, the first side plate 11, the second side plate 12 and the third side plate 13 are folded along the corresponding fold lines in sequence to form the inner support platform 31 and the outer support platform 32, thereby forming the first side plate assembly 10 and the buffer platform 30; another first side plate assembly 10 is folded in the same way to finally form two first side plate assemblies 10 and four buffer platforms 30.

[0060] Please see Figures 4 to 5 Next, the fourth side panel 14 and the fifth side panel 21 are folded along the corresponding fold lines, and each of the fifth side panels 21 and the sixth side panel 22 is folded along the corresponding fold lines in sequence to form a pressure strip. Then, the tongues 23 at both ends of the pressure strip are inserted into the corresponding two slots 15, and the other second side panel assembly 20 is folded in the same manner. Finally, the inner lining structure 100 is formed by folding a piece of paper.

[0061] This utility model also proposes a packaging box, which includes an inner lining structure 100. The specific structure of the inner lining structure 100 is as described in the above embodiments. Since this packaging box adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0062] In some embodiments, the packaging box further includes a box body and a lid that cooperates with the box body, and the inner lining structure 100 can be housed in the box body, thereby closing the box body with the lid to improve the reliability and safety of the panel light protection.

[0063] Optionally, the first side panel assembly 10 is also provided with a clearance groove 121, through which the user can remove the panel light from the receiving cavity 111, thereby improving the convenience and safety of disassembling the panel light.

[0064] The above are merely optional embodiments of this application and are not intended to limit this application.
