Description

Technical Field

[0001] This application relates to the field of packaging and transportation of smart voice-activated screens, and more particularly to an inner lining structure and cushioning packaging. Background Technology

[0002] With the continuous improvement of production technology, the demand for smart homes is constantly increasing. The centralized controller of the existing smart system, namely the voice-activated smart screen, serves as the local interaction center and control hub for all smart home devices. It connects all smart home appliances, features an all-in-one smart design, and integrates multiple interaction methods such as voice and touch. It has far-field sensitive voice pickup and provides a wealth of voice skills such as music, audiobooks, weather, and alarm clock. It also provides five major butler services: air, energy, health, lighting, and security. One device can control all smart home devices and, based on AI big data models and algorithms, provides users with more natural and proactive smart butler services.

[0003] Considering the transportation and storage of voice-activated smart screens, existing packaging lining structures generally use materials such as foam, sponge, and air cushions. Foam, to achieve good cushioning, often requires a thicker material, taking up a large packaging volume. Furthermore, its non-biodegradability and widespread use cause serious environmental problems. In terms of mold manufacturing, producing foam linings requires high precision and is costly. While sponge is soft, its resilience is limited, requiring a large quantity to ensure protection, leading to packaging volume expansion. Sponge is also highly absorbent and prone to deterioration, potentially requiring frequent replacement, increasing packaging material costs. Customized mold manufacturing for sponge also faces complex processes. Air cushions, although relatively thin, have weak pressure resistance. To ensure protection of the voice-activated smart screen, multiple air cushions may be needed, further increasing packaging volume. Air cushions are also easily damaged and have poor durability, requiring more packaging materials for replacement. Mold manufacturing for air cushions presents technical challenges in ensuring airtightness, increasing complexity and cost.

[0004] In summary, the existing packaging materials for smart voice displays are relatively thick and bulky, increasing the use of packaging materials. Furthermore, the existing lining structure is complex, making mold manufacturing inconvenient, which can lead to problems such as inconvenient mold opening and dimensional deviations, and also results in high processing and manufacturing costs. Utility Model Content

[0005] This application provides an inner lining structure and cushioning packaging to solve the technical problems of complex inner lining structures and inconvenient mold manufacturing in existing applications.

[0006] The lining structure provided by this utility model includes a first support lining and a second support lining integrally folded into shape. The first support lining and the second support lining are at least partially structurally connected, and the second support lining is fastened to at least a portion of the first support lining. An upper bearing cavity and a lower bearing cavity communicating below the upper bearing cavity are obtained at the opening of the lining structure. The upper bearing cavity has buffer side plates around its perimeter. The bottom surface of the upper bearing cavity is constructed as a support platform with a hollow center. The lower bearing cavity includes at least a bearing groove formed on a support plate.

[0007] The second support liner has at least two fitted support frames, each of which is a hollow structure. Each support frame has a supporting upright plate on one side where they fit together, serving as the side edge of each support frame. Each supporting upright plate has a bearing groove, which includes a bearing bottom surface. The bearing bottom surface and the bottom surface of the upper bearing cavity provide support for the packaged item to overcome its own weight. The side surface of the bearing groove and the buffer side plate of the upper bearing cavity respectively limit the movement of the packaged item along its circumferential direction. The packaged item does not contact the rest of the second support liner.

[0008] The first support liner includes a buffer side plate with a snap-fit ​​protrusion; the support platform has a gap; each of the support uprights also has a snap-fit ​​top surface with a snap-fit ​​groove, and the snap-fit ​​protrusion passes through the gap and engages with the snap-fit ​​groove.

[0009] The side of the bearing groove is a buffer side, and a stepped surface is formed between the snap-fit ​​top surface, the buffer side, and the bearing bottom surface. The buffer side and the bearing bottom surface are used to support and buffer the lower structure of the item to be packaged.

[0010] The inner lining structure is constructed as multiple folded edges connected in an extended plane. The inner lining structure includes a first folded edge constructed as a loop and a second folded edge connected to each side of the first folded edge. Two third folded edges are also connected to one side of the second folded edge arranged along a first direction, and the two third folded edges are spaced apart. The two second folded edges arranged along a second direction are also connected to a fourth folded edge, and each of the fourth folded edges is also connected to a fifth folded edge. There are creases between each folded edge. Each second folded edge, each of the third folded edges, each of the fourth folded edges, and each of the fifth folded edges are folded towards the same side of the first folded edge to form the second support lining.

[0011] The two fifth folds are folded to form the support plates, and the support plates divide the second support liner into two support frames. The third folds are inserted into the support frames respectively, and the third folds form folded edges.

[0012] The fifth folded edge is a U-shaped structure, the supporting bottom surface is the bottom surface of the U-shaped structure, the snap-fit ​​top surface is the top surface of the U-shaped structure, and the slot is formed on the top surface of the fifth folded edge.

[0013] The inner lining structure further includes a seventh folded edge constructed in a U-shape, a plurality of eighth folded edges connected to the inner edges of each side of the seventh folded edge, and a plurality of sixth folded edges connected to the outer edges of each side of the seventh folded edge, wherein one of the sixth folded edges is connected to a second folded edge; each of the eighth folded edges and each of the sixth folded edges are folded toward the same side of the seventh folded edge to form the first support lining.

[0014] The eighth fold edge is spaced apart along its own circumferential direction, and each eighth fold edge forms a buffer side plate, and each snap-fit ​​protrusion is formed on the inner circumferential side of each eighth fold edge.

[0015] This utility model also provides a cushioning packaging, which includes the aforementioned inner lining structure and a packaging box. The inner lining structure is installed inside the packaging box, and the inner lining structure is fitted or interference-fitted with each inner sidewall of the packaging box.

[0016] The packaging box has a self-locking bottom surface and a box body glued on one side, and also has an upper flap folded edge. The upper flap folded edge has upper flap cut edges on both sides. The upper flap folded edge is used to cover the top opening of the box body, and the upper flap cut edges are used to prevent tearing when the upper flap folded edge is fastened to the box body.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] The lining structure and cushioning packaging provided in this application embodiment consider the actual application scenarios of the lining structure. It is mainly used to provide support for the packaged item and to cushion it in the event of shaking or collision. For example, the packaged item in this application is a voice-activated smart screen. The cross-sectional structure of the voice-activated smart screen is T-shaped, comprising an upper structure and a lower structure. Based on this, the lining structure of this application, having a first supporting lining and a second supporting lining, is applied. The second supporting lining is used to fold towards the first supporting lining and engage with at least a portion of the structure of the first supporting lining. This forms a cushioned upper bearing cavity with four sides and a perimeter that is jointly limited by the bottom surface. This upper bearing cavity can support the upper structure of the voice-activated smart screen and limit the movement of the upper structure of the voice-activated smart screen along its perimeter or lateral direction, further providing cushioning. Furthermore, the upper supporting cavity is cushioned by buffer side plates around its perimeter to support the upper structure of the product. The bottom surface of the upper supporting cavity is constructed with a support platform that is not hollowed out in the middle. Based on this hollowed-out part, the lower structure of the product can extend into the lower supporting cavity. The lower supporting cavity includes at least a supporting groove formed on a supporting plate. The lower structure of the product can be accommodated through this supporting groove. That is, the bottom surface of the supporting groove can be used to support the lower structure of the voice smart screen, and the side surface of the supporting groove can be used to limit the movement of the lower structure of the packaged item along its own circumferential direction and further provide cushioning.

[0019] The inner lining structure of this application is used in the packaging of a voice-activated smart screen. The first and second support linings are integrally folded from cardboard of a preset thickness. The overall structure does not require assembly of other materials or structures besides the inner lining structure, nor does it require adhesive bonding. The molding process is simple, which can reduce packaging materials and reduce processing and manufacturing costs. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0037] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] In the smart home industry, to facilitate the transportation of related structural components, they are generally packaged individually before shipment. These related structural components can be understood as items to be packaged. In existing packaging for these items, an inner lining structure is typically used as the connection between the packaging box and the item to be packaged.

[0039] The following is a description of the inner lining structure, which has many important functions in the packaging field.

[0040] For example, the inner lining structure has a cushioning and protective function. Firstly, it provides shock absorption and cushioning: the inner lining structure typically uses elastic materials such as foam, sponge, and air cushions, which can effectively absorb and disperse external forces during transportation and handling, preventing damage to the packaged items due to collisions and vibrations. For instance, in electronic product packaging, foam linings can isolate mobile phones, tablets, etc., from external impacts, ensuring that the delicate electronic components inside are not damaged. Secondly, it provides corner protection: for items with sharp edges or protruding parts, the inner lining can be designed with specific shapes to provide focused protection for these vulnerable areas. For example, in glass product packaging, the inner lining is thickened at the corners or uses special cushioning materials to reduce the risk of breakage at the corners upon impact.

[0041] For example, the inner lining structure also has a fixing and positioning function. First, it can provide precise positioning: the inner lining structure can be customized according to the shape and size of the packaged items, allowing the items to be accurately placed in a specific position and preventing them from shifting inside the packaging. Second, it can provide multi-item separation: when multiple items need to be placed inside the packaging, the inner lining can be designed as a layer or compartment to separate different items, not only fixing them in place but also preventing them from rubbing against each other, scratching, or getting mixed up.

[0042] Based on this, although the existing lining structures demonstrate many functions, most of them use materials such as foam plastic, sponge, and air cushion. In order to achieve the corresponding functions, it is necessary to open molds to obtain lining structures with corresponding functions. The material thickness and packaging volume of the existing lining structures are relatively large, which increases the use of packaging materials. In addition, the lining structures in the packaging of existing applications are complex, and mold manufacturing is inconvenient, which will cause problems such as inconvenience in mold opening and dimensional deviation, and has high processing and manufacturing costs.

[0043] To alleviate the aforementioned problems, this application provides an inner lining structure and cushioning packaging, which is applied to the packaging of an item to be packaged. For example, the item to be packaged is a voice-activated smart screen. Considering that the voice-activated smart screen may experience shaking and collisions during transportation, the inner lining structure of this application also provides a four-sided cushioning and restraining function for the item to be packaged (i.e., the voice-activated smart screen). Furthermore, the inner lining structure of this application can employ an integrally folded first support lining and a second support lining to support the item to be packaged and cushion shaking and collisions during transportation. It should be noted that the entire molding process of the inner lining structure provided in this application is achieved through folding and fastening, facilitating molding and eliminating the need for mold opening to produce the required structure.

[0044] refer to Figures 1-10 This disclosure provides an inner lining structure 1A, which includes a first support lining 11A and a second support lining 12A integrally folded together. The second support lining 12A is engaged with at least a portion of the structure of the first support lining 11A. An upper bearing cavity 112A and a lower bearing cavity communicating below the upper bearing cavity are obtained at the opening of the inner lining structure. The upper bearing cavity 112A has buffer side plates 111A around its perimeter. The bottom surface of the upper bearing cavity 112A is constructed as a support platform with a hollow center. The lower bearing cavity includes at least a bearing groove 52 formed on a support upright plate 1211A.

[0045] The inner lining structure 1A of this application embodiment includes an upper supporting cavity 112A that supports the upper structure of the voice-activated smart screen and limits the movement of the upper structure of the voice-activated smart screen along its periphery or lateral direction, further providing cushioning. Furthermore, the upper supporting cavity 112A is cushioned by buffer side plates 111A around its periphery to support the upper structure of the product. The bottom surface of the upper supporting cavity 112A has a centrally hollowed-out support platform. Based on this centrally hollowed-out portion, the lower structure of the product can extend into the lower supporting cavity. The lower supporting cavity includes at least one supporting groove 52 formed on a supporting upright plate 1211A. This supporting groove 52 can accommodate the lower structure of the product; that is, the bottom surface of the supporting groove 52 can support the lower structure of the voice-activated smart screen, and the side surface of the supporting groove can limit the movement of the lower structure of the packaged item along its periphery, further providing cushioning.

[0046] It should be further noted that the bearing groove 52 used in this embodiment is formed on the support plate 1211A. The support plate 1211A is made of folded cardboard and has a cardboard structure. The actual contact area between the bearing groove 52 and the lower structure of the product is very small, but it can play a role in supporting the lower structure and limiting and buffering in the circumferential direction, which can save structural materials.

[0047] Considering the actual application scenarios of the inner lining structure 1A, it is mainly used to provide support for the packaged item 1B and to provide cushioning for the packaged item 1B in the event of shaking or collision; for example, the packaged item 1B of this application is a voice smart screen, and the cross-sectional structure of the voice smart screen is T-shaped, which includes an upper structure and a lower structure.

[0048] It should be noted that the voice-activated smart screen is placed inside the upper supporting cavity 112A and does not protrude from the top surface of the upper supporting cavity 112A, thus avoiding interference problems.

[0049] Furthermore, the second support liner 12A includes at least two fitted support frames 121A, each support frame 121A having a hollow structure. Each support frame 121A has a support plate 1211A on one side where they are fitted together, serving as the side of each support frame 121A. Each support plate 1211A has the aforementioned bearing groove 52. The bottom surface of the bearing groove 52 and the bottom surface of the upper bearing cavity 112A provide support for the packaged item 1B to overcome its own weight. The side surface of the bearing groove 52 and the periphery of the upper bearing cavity 112A respectively limit the movement of the packaged item 1B along its own periphery. The packaged item 1B has no contact with the other parts of the second support liner 12A.

[0050] In this way, the bearing groove 52 can be used to support the lower structure of the voice-activated smart screen, and the inner side of the bearing groove 52 on each supporting plate 1211A can provide limiting and buffering for the lower structure of the voice-activated smart screen. In summary, the bearing groove 52 and the bottom surface of the upper bearing cavity 112A provide support for the packaged item 1B (i.e., the voice-activated smart screen) to overcome its own weight, and the sides of the bearing groove 52 and the upper bearing cavity 112A respectively limit the movement of the lower and upper structures of the packaged item 1B along their circumferential directions. Furthermore, the packaged item 1B does not contact the other positions of the second supporting liner 12A. Thus, the support and limiting of the lower structure of the packaged item 1B can be achieved using only the simple structure of the bearing groove 52 of the supporting plate 1211A, which can save structural materials.

[0051] For example, the bearing groove 52 of the support plate 1211A here can also be understood as a bearing concave edge. The support plate 1211A used in this application embodiment is a cardboard structure. The bearing groove 52 is an edge formed on the support plate 1211A after stamping. It is equivalent to the area of ​​the thickness line width of the cardboard structure multiplied by the line length of each surface of the bearing groove 52. This area is small and approximately equal to the bearing concave edge playing a supporting and limiting role.

[0052] Thus, when the inner lining structure 1A of this application is applied to the packaging of a voice-activated smart screen, the first support lining 11A and the second support lining 12A are integrally folded from cardboard of a preset thickness. The overall structure does not require assembly of any other materials or structures besides the inner lining structure 1A, nor does it require adhesive bonding. The molding process is simple, which can reduce packaging materials and lower processing and manufacturing costs.

[0053] For example, at least a portion of the structure of the second support liner 12A and the first support liner 11A are engaged to form an upper bearing cavity that is buffered around the perimeter and limited by the perimeter and the bottom surface. It can be understood that the upper bearing cavity 112A has a buffer plate-like structure arranged around the perimeter of the upper bearing cavity 112A and a support plate-like structure located on the bottom surface of the upper bearing cavity 112A.

[0054] For example, the mutually fitted support frames 121A in the second support liner 12A can be understood as each support frame 121A having a stable box-like structure for enclosing support. For example, the enclosing support may be located on one side of each support frame 121A, or the enclosing support may be located on two sides of each support frame 121A, or the enclosing support may be located on multiple sides of each support frame 121A.

[0055] For example, the first support liner 11A and the second support liner 12A are interconnected box-like structures. The first support liner 11A and the second support liner 12A are folded and fastened to form an integrally molded box structure with support and buffer space.

[0056] Considering the specific fastening scheme of the first support liner 11A and the second support liner 12A, in the inner liner structure 1A provided in this application, the first support liner 11A includes a buffer side plate 111A, and the buffer side plate 111A has a snap-fit ​​protrusion 81; the second support liner 12A includes a first folded edge 1, and the first folded edge 1 has a gap hole 11, that is, the first folded edge 1 forms the aforementioned support platform after being folded, that is, the support platform has a gap hole 11; each support upright plate 1211A also has a snap-fit ​​top surface, and the snap-fit ​​top surface has a snap-fit ​​groove 51, and the snap-fit ​​protrusion 81 passes through the gap hole 11 and snaps into the snap-fit ​​groove 51.

[0057] In this way, by folding, the buffer side plate 111A, the first folded edge 1 and the support plate 1211A can be fastened together. The snap-fit ​​protrusion 81 on the buffer side plate 111A can pass through the gap hole 11 on the first folded edge 1 and fasten with the snap-fit ​​groove 51 on the support plate 1211A. That is, without the need for additional structural components or processes, the buffer side plate 111A, the first folded edge 1 and the support plate 1211A can be fixed together. In other words, a stable structure in which the first support liner 11A and the second support liner 12A are connected can be obtained by folding and fastening.

[0058] This application does not limit the shape and size of the snap-fit ​​protrusion 81, the slot 11, and the groove 51, as long as the three cooperate with each other to achieve the effect of the snap-fit ​​protrusion 81 passing through the slot 11 and engaging with the groove 51. For example, the snap-fit ​​protrusion 81 can be rectangular, the slot 11 is a small hole structure adapted to the thickness of the snap-fit ​​protrusion 81, and the structural size of the slot 11 should not be too large. Furthermore, the groove width of the groove 51 is a groove-shaped structure adapted to the thickness of the snap-fit ​​protrusion 81. For example, the groove 51 can be a U-shaped groove or a V-shaped groove, or the groove 51 can be any of a regular shape or an irregular shape.

[0059] For example, one side of the buffer side plate 111A has a snap-fit ​​protrusion 81, and both sides of the snap-fit ​​protrusion 81 also have abutting edges. When the snap-fit ​​protrusion 81 passes through the gap 11, the abutting edges can abut against the first folded edge 1, and the buffer side plate around the perimeter and the first folded edge 1 form the aforementioned upper bearing cavity 112A.

[0060] Considering the specific support and cushioning scheme of the second support liner 12A for the packaged item 1B, in the inner liner structure 1A provided in this application, the side of the bearing groove 52 is a cushioning side 522, the bottom surface of the bearing groove 52 is a bearing bottom surface 521, and a stepped surface is formed between the snap-fit ​​top surface, the cushioning side 522 and the bearing bottom surface 521. The cushioning side 522 and the bearing bottom surface 521 are used to support and accommodate the lower structure of the packaged item 1B. In addition, the upper bearing cavity 112A is used to support the upper structure of the packaged item 1B and provide cushioning along its own radial direction to the periphery of the upper structure.

[0061] Each support plate 1211A has a snap-fit ​​top surface with a snap-fit ​​groove 51 for limiting the snap-fit ​​protrusion 81 in the first support liner 11A. Each support plate 1211A not only has a snap-fit ​​top surface with a groove 51 for connecting with a portion of the first support liner 11A, but also serves as a structural component in the second support liner 12A primarily supporting the upper structure of the packaged item 1B. Each support plate 1211A, as a structural component in the second support liner 12A primarily supporting the lower structure of the packaged item 1B, is positioned below the upper structure corresponding to the lower structure of the packaged item 1B. The bearing bottom surface 521 of the bearing groove 52 on each support plate 1211A for supporting the lower structure is located below the snap-fit ​​top surface. To further consider that the packaged item 1B will not experience unnecessary shaking in the second support liner 12A, a buffer side surface 522 is provided on each of the support uprights 1211A between the corresponding snap-fit ​​top surface and the bearing bottom surface 521. For example, the buffer side surface 522 can be a single plane, or it can be a curved surface or other shaped structural surface that adapts to the lower structural contour of the packaged item 1B.

[0062] In this way, a buffer side surface 522 is provided between the snap-fit ​​top surface of each support plate 1211A and the bearing bottom surface 521. The buffer side surface 522 can limit the bearing space of the lower structure of the packaged item 1B in the second support liner 12A, thereby preventing uncontrollable shaking of the lower structure of the packaged item 1B in the bearing space of the second support liner 12A, which would affect the structural stability of the second support liner 12A and the overall inner liner structure 1A.

[0063] Considering the specific structural scheme of each support frame 121A in the second support liner 12A, in the liner structure 1A provided in this application, one side face of the support frame 121A has two folded edges, each folded edge is used to fit into the side opening of each support frame 121A to form a stable support structure with the side support plate 1211A.

[0064] In this way, the structural stability of each support frame 121A can be ensured under the interlocking application of the two folded edges, and the stable support function can also be provided for each support plate 1211A, avoiding the failure of each support plate 1211A to achieve the functions of support and engagement.

[0065] Taking a support frame 121A with only one side having two folded edges as an example, that is, the support frame 121A does not have an interlocking or snap-fitting structure on the opposite side of that side. In each support frame 121A, only one side has these two folded edges. It should be noted that in the second support liner 12A, there are two mutually fitting support plates 1211A between each support frame 121A. The two support plates 1211A serve as reinforcing ribs in the second support liner 12A. The interlocking of the two folded edges can prevent the two support plates 1211A from being isolated in the middle space of the second support liner 12A. Specifically, the two folded edges can further ensure that the two support frames 121A form stable square frame structures respectively.

[0066] This application does not limit the structure, shape, and size of the constituent surfaces of the support frame 121A. As long as the support frame 121A has at least two fitting support plates 1211A and a folded edge on one side, it is sufficient. In this way, it is not necessary to set buffers or supports at multiple positions around the lower structure of the packaged item 1B. Only one side structure of the bearing bottom surface 521 of the bearing groove 52 of the support plate 1211A is needed for support. Moreover, the streamlined buffer side 522 formed by stamping of the support plate 1211A is sufficient to limit the position of the lower structure of the packaged item 1B along its own circumferential direction. It does not need to have excessive contact with the lower structure of the packaged item 1B to achieve the support and buffer functions. Furthermore, the lower structure of the packaged item 1B will not shake within the second support liner 12A.

[0068] Considering the specific molding scheme of the second support liner 12A in the inner liner structure 1A, the inner liner structure 1A provided in this application is constructed as multiple folded edges connected in the extension plane. The inner liner structure 1A includes a first folded edge 1 constructed as a loop structure and a second folded edge 2 connected to each side of the first folded edge 1. Two third folded edges 3 are also connected to one side of the second folded edge 2 arranged along the first direction, and the two third folded edges 3 are spaced apart. The two second folded edges 2 arranged along the second direction are also connected to a fourth folded edge 4, and each fourth folded edge 4 is also connected to a fifth folded edge 5. There are creases between each folded edge. Each second folded edge 2, each third folded edge 3, each fourth folded edge 4 and each fifth folded edge 5 are folded towards the same side of the first folded edge 1 to form the second support liner 12A.

[0069] This application does not limit the shape and size of the first fold 1, second fold 2, third fold 3, fourth fold 4, and fifth fold 5, as long as the first fold 1, second fold 2, third fold 3, fourth fold 4, and fifth fold 5 together form a frame-like structure with the aforementioned functional characteristics of the second support liner 12A. Furthermore, the structure of the second support liner 12A obtained by folding in this application does not require bonding or assembly of other structural components, and a structurally stable inner liner structure 1A can be directly obtained, making the overall processing technology simpler.

[0070] It should be noted that the first fold 1, the second fold 2, the third fold 3, the fourth fold 4 and the fifth fold 5 of the second support liner 12A used to form the inner liner structure 1A in this application are all interconnected planar cardboard structures.

[0071] For example, the first fold 1 is constructed as a loop-shaped structure, and the outer edge of the first fold 1 serves as the reference line for folding, which can be used to define the approximate volume of the internal space of the three-dimensional structure formed by the inner lining structure 1A after folding.

[0072] Considering the inner lining structure 1A, the second support lining 12A is formed by folding. In order to obtain the second support lining 12A with the aforementioned stable shape, the extended planar structure is further described in correspondence with the aforementioned support plate 1211A, support frame 121A and folded edge.

[0073] Specifically, in the inner lining structure 1A provided in this application, the two fifth folds 5 are folded to form the aforementioned support plates 1211A, and the support plates 1211A divide the second support lining 12A into two support frames 121A. Each third fold 3 is inserted into each support frame 121A, and each third fold 3 forms a folded edge.

[0074] In this way, by using the foldable third fold 3 and fifth fold 5, two adjacent support frames 121A with stable structural performance can be obtained, and it can be ensured that the two support uprights 1211A formed by the two fifth folds 5 of the cardboard can simultaneously play the role of limiting and engaging the snap-fit ​​protrusion 81 of the first support liner 11A and supporting and limiting circumferential shaking of the lower structure of the package 1B.

[0075] Figure 2 The planar extended structure is the initial state of the inner lining structure 1A. The following defines the direction of the screen facing the user as upward and the direction of the screen facing the inside of the display as downward, to illustrate the folding process of the inner lining structure 1A:

[0076] Using the first folded edge 1 as the folding reference plane, the second folded edge 2 on the circumference of the first folded edge 1 is folded downwards. The fourth folded edge 4, connected to the second folded edge 2, can then continue to fold around the first folded edge 1 until the fifth folded edge 5 is folded to a perpendicular angle to the first folded edge 1. At this point, the two fifth folded edges 5 remain close together, and each fifth folded edge 5, along with its connected fourth folded edge 4, second folded edge 2, and first folded edge 1, forms an unclosed opening structure. There is no connection between the fifth folded edge 5 and the first folded edge 1. In this state, although an opening structure is formed, the connection is unstable. The two third folded edges 3, connected to one side of the second folded edge 2, are then inserted into the aforementioned two opening structures. Thus, using the third folded edge 3 as the second support liner 12A functioning as the folding edge, an initially stable opening frame structure is formed. However, since there is still no connection between the fifth folded edge 5 and the first folded edge 1, this initially stable opening frame structure is only temporarily formed and cannot bear weight.

[0077] Considering the stable positioning scheme of the fifth fold 5 relative to the first fold 1, in the lining structure 1A provided in this application, the fifth fold 5 is constructed as a U-shaped structure, the bearing bottom surface 52 is the bottom surface of the U-shaped structure, the snap-fit ​​top surface is the top surface of the U-shaped structure, and the snap-fit ​​groove 51 is formed on the top surface of the fifth fold 5.

[0078] In this way, the slot 51 on the top surface of the fifth fold 5 can engage with the locking protrusion 81 that passes through the hole 11 of the first fold 1. That is, the fifth fold 5 and the first fold 1 are relatively fixed. This relative fixation can be understood as a detachable fixed connection.

[0079] Based on the folding scheme of the second support liner 12A as described above, and considering the folding scheme of the first support liner 11A of this application, the inner liner structure 1A provided by this application further includes a seventh fold 7 constructed as a loop structure, a plurality of eighth folds 8 connected to the inner edges of each side of the seventh fold 7, and a plurality of sixth folds 6 connected to the outer edges of each side of the seventh fold 7, wherein one of the sixth folds 6 is connected to a second fold 2; each of the eighth folds 8 and each of the sixth folds 6 are folded toward the same side of the seventh fold 7 to form the first support liner 11A.

[0080] It should be noted that the folding direction of each edge in the first support liner 11A is opposite to the folding direction of each edge in the second support liner 12A.

[0081] In this way, with the seventh fold 7 as the folding reference surface, the sixth fold 6 and the eighth fold 8 set around the perimeter are folded towards the direction of the second support liner 12A. When the second support liner 12A is folded again towards the first support liner 11A, each of the sixth fold 6 can cover the outside of the corresponding second fold 2. Moreover, there is only a surface-to-surface contact between each of the sixth fold 6 and the corresponding second fold 2. There is no adhesive or locking mechanism for fixing.

[0082] Figure 2 The planar extended structure is the initial state of the inner lining structure 1A. The following defines the direction of the screen facing the user as upward and the direction of the screen facing the inside of the display as downward, to illustrate the folding process of the inner lining structure 1A:

[0083] The folding process of the second support liner 12A is as follows: taking the first folded edge 1 as the folding reference plane, the second folded edge 2 on the circumferential side of the first folded edge 1 is folded downwards, and then the fourth folded edge 4 connected to the second folded edge 2 can continue to be folded around the first folded edge 1 until the fifth folded edge 5 is folded to a perpendicular angle with the first folded edge 1. At this time, the two fifth folded edges 5 are kept close together, and each fifth folded edge 5 and the fourth folded edge 4, the second folded edge 2 and the first folded edge 1 connected to it form an unclosed mouth-shaped structure. There is no connection between the fifth folded edge 5 and the first folded edge 1. In this state, although a mouth-shaped structure is formed, the connection is not stable. Continue by inserting the two third edges 3 connected to the second edge 2 on one side into the two mouth-shaped structures mentioned above. In this way, the third edge 3 serves as the second support liner 12A with the function of the folded edge, forming a mouth-shaped frame structure with initial positioning stability. However, since there is still no connection and positioning relationship between the fifth edge 5 and the first edge 1, the mouth-shaped frame structure with initial positioning stability can only be temporarily formed and cannot bear the weight.

[0084] Furthermore, the folding process of the first support liner 11A is as follows: taking the seventh fold 7 as the folding reference plane, the sixth fold 6 and the eighth fold 8 arranged around the perimeter are folded towards the direction of the second support liner 12A, that is, each sixth fold 6 and each eighth fold 8 is folded upwards. Then, the second support liner 12A, which has been initially stabilized by the aforementioned folding, is bent again towards the first support liner 11A that was just bent. Each sixth fold 6 can cover the outside of the corresponding second fold 2, and the first fold 1 can be located below the seventh fold 7 and the eighth fold 8 after folding. At this time, the first support liner 11A and the second support liner 12A still have a degree of freedom in the Z direction.

[0085] Considering that the degree of freedom in the Z direction between the first support liner 11A and the second support liner 12A is 0, in the inner liner structure 1A provided in this application, each eighth fold 8 is spaced apart along its own circumferential direction, and each eighth fold 8 forms a buffer side plate 111A, and each snap-fit ​​protrusion 81 is formed on the inner circumferential side of each eighth fold 8.

[0086] In this way, the snap-fit ​​protrusions 81 of each of the eighth folds 8 can pass through the corresponding slots 11 of the first fold 1, and thus engage with the slots 51 of the fifth fold 5. Furthermore, under the constraints of this engagement relationship, refer to... Figure 6 The eighth fold 8 can stably form a buffer limit around the upper structure of the packaged item 1B below the seventh fold 7.

[0087] For example, the buffer side plate 111A formed by the eighth fold 8 can be a buffer upright plate. The buffer upright plate can form a state of fitting, abutting or wrapping around the upper structure of the package 1B. At the same time, the first fold 1 can directly support the upper structure of the package 1B. That is, the first fold 1 and each of the eighth folds 8 together form the aforementioned upper bearing cavity 112A.

[0088] For example, the seventh fold 7, the eighth fold 8 and the first fold 1 together form a stepped groove structure, which is used to support the upper structure of the packaged item 1B, that is, the upper structure of the voice smart screen.

[0089] For the inner lining structure 1A in the final form after folding and forming of this application, the U-shaped groove of the fifth fold 5 provides the main support and limiting function for the lower structure of the package 1B. The bearing bottom surface 521 (i.e., bearing bottom edge) and the buffer side surface 522 (i.e. buffer side) of the bearing groove 52 of the fifth fold 5 play a major supporting and limiting function. At the same time, the groove of the snap-fit ​​top surface of the fifth fold 5 can also stably limit the eighth fold 8.

[0090] In summary, the inner lining structure 1A provided in this application can be folded multiple times through a planar extension structure to form a three-dimensional box-shaped structure. Moreover, the three-dimensional box-shaped structure can obtain a stable support structure shape by simply locking and limiting, without the need for additional limiting assembly process or additional assembly connection structure. Furthermore, the flat plate forming process of the planar extension structure is simple and does not require designing mold opening angle or mold opening size, which can reduce packaging materials and reduce processing and manufacturing costs.

[0091] refer to Figure 9 and Figure 10 This application embodiment also provides a cushioning package, which includes the aforementioned inner lining structure 1A and a packaging box 2A. The inner lining structure 1A is installed inside the packaging box 2A, and the inner lining structure 1A is fitted or interference-fitted with each inner sidewall of the packaging box 2A.

[0092] Further reference Figure 9 The packaging box 2A has a planar extended structure. Specifically, the packaging box 2A has a self-locking bottom surface and a box body glued on one side. It also has an upper flap fold 27. The upper flap fold 27 has upper flap cut edges 28 on both sides. The upper flap fold 27 is used to cover the top opening of the box body. The upper flap cut edges 28 are used to prevent tearing when the upper flap fold 27 is fastened to the box body.

[0093] In this way, the self-locking bottom structure can prevent the bottom of the packaging box 2A from being opened unintentionally, and the upper flap knife edge 28 can prevent the edge from tearing when the upper flap fold 27 is fastened to the box body.

[0094] Specifically, the planar extension structure of the packaging box 2A includes a first self-locking fold 21, a second self-locking fold 22, a third self-locking fold 23, and a fourth self-locking fold 24. By combining and folding the first self-locking fold 21, the second self-locking fold 22, the third self-locking fold 23, and the fourth self-locking fold 24, the bottom surface of the self-locking structure of the packaging box 2A of this application can be obtained.

[0095] Specifically, the packaging box 2A also includes a first top cover fold 25 and a second top cover fold 26. The box body, which is glued on one side, has a top opening. The first top cover fold 25 and the second top cover fold 26 are folded over relative to the top opening. Combined with the snapping action of the top cover fold 27 with the top flap cut 28, the inner liner structure 1A carrying the packaged items can be completely stored inside the packaging box 2A.

[0096] To further ensure transportation safety, the outer perimeter of packaging box 2A can be sealed with plastic to prevent damage to or failure to open the packaging box 2A.

[0097] It should be noted that the package 1B is placed in the aforementioned inner lining structure 1A, and the inner lining structure 1A carrying the package 1B is placed inside the packaging box 2A. The internal space of the packaging box 2A is adapted to accommodate the inner lining structure 1A, and the inner lining structure 1A will not shake inside the packaging box 2A.

[0098] In summary, the inner lining structure 1A and cushioning packaging of this application are adopted. Considering the actual application scenarios of the inner lining structure 1A, it is mainly used to provide support for the packaged item 1B and to provide cushioning for the packaged item 1B in the event of shaking or collision. For example, the packaged item 1B of this application is a voice smart screen. The cross-sectional structure of the voice smart screen is T-shaped, which includes an upper structure and a lower structure.

[0099] Based on this, the inner lining structure 1A of this application, having a first support liner 11A and a second support liner 12A, wherein the second support liner 12A is used to fold toward the first support liner 11A and to fasten with at least a portion of the structure of the first support liner 11A, thereby forming an upper bearing cavity 112A with four-sided buffering and four-sided positioning with the ground. The upper bearing cavity 112A can be used to support the upper structure of the voice smart screen and provide buffering around the four sides of the upper structure of the voice smart screen.

[0100] Furthermore, the second support liner 12A includes two mating support frames 121A, each with two or more support uprights 1211A on one mating side, and each support upright 1211A having a bearing bottom surface 521. Thus, the bearing bottom surface 521 can support the lower structure of the voice-activated smart screen, and the buffer sides 522 on both sides of the bearing bottom surface 521 on each support upright 1211A can provide cushioning for the lower structure of the voice-activated smart screen. In summary, the bearing bottom surface 521 and the bottom surface of the upper bearing cavity 112A provide support for the packaged item 1B (i.e., the voice-activated smart screen) to overcome its own weight. Furthermore, the packaged item 1B does not contact the other parts of the second support liner 12A. That is, the lower structure of the packaged item 1B does not contact the other parts of the second support liner 12A. In this way, the support and limiting of the lower structure can be achieved solely through the support plate 1211A (with its bearing groove 52), which can save on the structural materials of the second support liner 12A and the overall inner liner structure 1A.

[0101] The inner lining structure 1A and packaging box 2A of this application are used in the packaging of a voice-enabled smart screen. The first support lining 11A and the second support lining 12A are integrally folded from cardboard of a preset thickness. The overall structure does not require assembly of other materials or structures besides the inner lining structure 1A, nor does it require adhesive bonding. The molding process is simple, which can reduce packaging materials and reduce processing and manufacturing costs.

[0102] In summary, the cardboard folding and molding inner lining structure 1A used in this application for a voice-activated smart screen has the following advantages:

[0103] Firstly, in terms of cost and process: It is inexpensive, as cardboard is widely available and relatively cheaper than other packaging materials such as plastics and metals, thus reducing packaging costs. Furthermore, the folding and forming process is relatively simple, requiring no complex equipment or processes, further saving costs. It is also easy to process; cardboard is easy to cut and fold, and can be quickly folded into various shapes and sizes of inner lining structures according to design requirements, adapting to the packaging needs of different products. It boasts high production efficiency and can quickly respond to market orders.

[0104] Secondly, in terms of performance and function: It offers excellent cushioning performance. The cardboard itself has a certain degree of elasticity and toughness, and after folding and shaping, the cushioning effect can be enhanced through structural design, effectively protecting products from damage caused by collisions, vibrations, and other external forces during transportation and storage. It boasts high space utilization. Precise design can be tailored to the product's shape and size. Through reasonable folding, it tightly fits the product, effectively filling the space between the product and the outer packaging, reducing packaging volume, facilitating transportation and storage, and lowering logistics costs. It also exhibits excellent environmental performance. Cardboard is a recyclable and biodegradable material, meeting environmental protection requirements. Its use will not cause serious environmental pollution, helping companies establish a positive environmental image.

[0105] In addition, cardboard printing is highly adaptable. Its smooth surface facilitates various printing and coating surface treatments, allowing for the printing of product information and patterns, thus promoting and beautifying products and enhancing their appeal. Furthermore, it is easy to assemble and disassemble; multiple folded cardboard liners can be easily combined for packaging complex or multi-part products. After use, it is also easy to disassemble, facilitating recycling or reuse.

[0106] Furthermore, the cardboard folded and integrally formed inner lining structure 1A is applied to the packaging of the voice smart screen. Even if a collision occurs during transportation, the inner lining structure 1A can ensure that it provides cushioning support to the voice smart screen to resist the collision. In this way, it can avoid the problem that the components of the voice smart screen will separate due to the collision or that the electronic components such as the circuit of the voice smart screen will fail to realize the smart function due to the collision.
