[0049] The invention discloses a packaging structure to meet the requirements of buffering performance.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] The inventors have found that the current packaging materials need to use EPE (Expanded Polyethylene) and other foam materials that can form a closed-cell structure as cushioning materials. For environmental protection requirements, the above cushioning materials need to be recycled, and the recycling of the above cushioning materials requires the establishment of a complete recycling chain, which limits recycling. If the packaging materials are environmentally friendly materials such as paper materials, they can meet the needs of deplasticization and there is almost no difficulty in recycling. However, the cushioning performance of the current packaging structures (such as cardboard or paper plastic) made of environmentally friendly materials (paper materials) cannot meet the requirements of cushioning performance.

[0052] Therefore, the embodiment of the present invention provides a packaging structure, which can effectively improve the cushioning effect even if it is made of environmentally friendly materials to meet the requirements of cushioning performance. Of course, it is not excluded to use other non-environmentally friendly materials.

[0053] like Figure 1-Figure 18 As shown, the packaging structure includes a packaging box 100 and a buffer component disposed in the packaging box 100. The packaging box 100 can provide a storage space for the product 001 and the buffer component, and the buffer component can be located between the product 001 and the packaging box 100 to achieve a buffering effect. That is, during the packaging process of the product 001, the product 001 contacts the buffer component, and the buffer component contacts the packaging box 100, so that the buffer component is located between the product 001 and the packaging box 100. In the case where the packaging box 100 receives an external impact force or other impact force (such as the impact force received by the packaging box 100 in contact with the ground due to falling), the external impact force or other impact force needs to pass through the buffer component during the process of being transmitted to the product 001, thereby alleviating the force to protect the product 001.

[0054] The buffer assembly includes a first structural layer 300 and a second structural layer 200 , wherein the first structural layer 300 is used to carry the product 001 , and the second structural layer 200 is used to connect the first structural layer 300 to provide buffering for the first structural layer 300 .

[0055] The first structural layer 300 has a first area 310 and a second area 320 at least partially connected to the first area 310. The first area 310 is used to support the product 001, and the second area 320 is used to limit the position of the product 001. That is, the second area 320 is used to limit the movement of the product 001 relative to the first structural layer 300, so as to ensure that the first area 310 is arranged corresponding to the area where the product 001 is supported, so that the first area 310 is used to provide support force for the product 001.

[0056] The second structural layer 200 has a third region 210 corresponding to the first region 310 and a fourth region 220 corresponding to the second region 320. That is, when the first structural layer 300 and the second structural layer 200 are connected, the third region 210 of the second structural layer 200 corresponds to the first region 310 of the first structural layer 300, and the fourth region 220 of the second structural layer 200 corresponds to the second region 320 of the first structural layer 300.

[0057] In which, taking the correspondence between the third region 210 of the second structural layer 200 and the first region 310 of the first structural layer 300 as an example, in the state where the first structural layer 300 is connected to the second structural layer 200, along the arrangement direction of the first structural layer 300 and the second structural layer 200, the projection of the first region 310 and the projection of the third region 210 may partially or completely overlap, so that the first region 310 and the third region 210 at least include a partially overlapping region along the arrangement direction of the first structural layer 300 and the second structural layer 200. This partially overlapping region has a structure that can contact or interact with each other, so as to achieve the effect of the third region 210 providing a buffer to the first region 310. In which, when the projection of the first region 310 and the projection of the third region 210 are completely overlapped, the projection area of ​​the first region 310 is the same as the projection area of ​​the third region 210, and the projection edge of the first region 310 is aligned with the projection edge of the third region 210. The projection of the first area 310 may not completely overlap with the projection of the third area 210, so that the projection area of ​​the first area 310 is larger or smaller than the projection area of ​​the third area 210, and the projection edge of the first area 310 may be partially aligned or completely misaligned with the projection edge of the third area 210. The specific setting depends on actual needs and is not specifically limited here.

[0058] Similarly, the fourth region 220 of the second structural layer 200 corresponds to the second region 320 of the first structural layer 300. When the first structural layer 300 is connected to the second structural layer 200, along the arrangement direction of the first structural layer 300 and the second structural layer 200, the projection of the second region 320 and the projection of the fourth region 220 may partially or completely overlap, so that the second region 320 and the fourth region 220 at least include a partially overlapping region along the arrangement direction of the first structural layer 300 and the second structural layer 200. This partially overlapping region has a structure that can contact or interact with each other, so that the fourth region 220 provides a buffering effect on the second region 320.

[0059] Furthermore, the first region 310 and the third region 210 form a first buffer structure, and / or the second region 320 and the fourth region 220 form a second buffer structure, so both the first buffer structure and the second buffer structure can provide buffering for the first structural layer 300, thereby having a buffering effect on the product 001. That is, when the first structural layer 300 and the second structural layer 200 are connected, the first buffer structure and / or the second buffer structure can serve as a structure for the second structural layer 200 to provide buffering for the first structural layer 300.

[0060] The first buffer structure may be located in a region where the first region 310 and the third region 210 overlap along the arrangement direction of the first structure layer 300 and the second structure layer 200. The second buffer structure may be located in a region where the second region 320 and the fourth region 220 overlap along the arrangement direction of the first structure layer 300 and the second structure layer 200.

[0061] The packaging structure provided in the embodiment of the present application can, through the cooperation of the first structural layer 300 and the second structural layer 200, on the basis of providing support stability for the product 001, realize the buffering effect of the second structural layer 200 on the first structural layer 300 through the first buffer structure and / or the second buffer structure, thereby playing an effective buffering role and meeting the requirements of buffering performance.

[0062] Among them, product 001 can be electronic equipment such as servers, laptops, mobile phones, etc., or it can be material products that require buffered transportation, etc.

[0063] Since the first area 310 and the third area 210 form a first buffer structure and / or the second area 320 and the fourth area 220 form a second buffer structure, that is, the first structural layer 300 and the second structural layer 200 can cooperate to form a buffer structure, thereby avoiding the use of foam materials (plastics) that can form a closed-cell structure as components in the packaging structure. The first structural layer 300 and the second structural layer 200 can be made of environmentally friendly materials such as paper-plastic materials, cardboard, wood materials or bamboo materials, so as to meet the requirements of buffer performance on the basis of meeting environmental protection requirements.

[0064] In some embodiments, the first region 310 and the third region 210 may form a first buffer structure, and the second region 320 and the fourth region 220 may form a second buffer structure.

[0065] Since the first area is used to support product 001, the first buffer structure can provide effective buffering for the support surface (such as the first surface) of product 001 supported by the first area. In the process of being impacted by external force, the impact on the support surface of product 001 is reduced. In addition, since the second area is used to limit product 001, the second buffer structure can provide effective buffering for the limiting part (such as the side of product 001 or the edge of the first surface) of product 001 limited by the second area. In the process of being impacted by external force, the impact on product 001 due to shaking is reduced.

[0066] In other embodiments, only the first region 310 and the third region 210 may form a first buffer structure. That is, the product 001 can keep the first region supported on the supporting surface (such as the first surface) of the product 001 under the limitation of the second region. The first buffer structure can effectively buffer the supporting surface of the product 001. When the product 001 is impacted by external force, the impact on the supporting surface of the product 001 is reduced.

[0067] In other embodiments, only the second area 320 and the fourth area 220 may form a second buffer structure. That is, when the product 001 is supported by the first area 310, the product 001 tends to shake (displaced relative to the first area 310) when subjected to external impact, so that the limiting part of the product 001 will collide with the second area. The second buffer structure can provide effective buffering for the limiting part of the product 001. When subjected to external impact, the impact of the shaking on the product 001 is reduced.

[0068] In specific applications, adjustments can be made based on the actual buffering requirements of product 001, and a buffer component with a first buffer structure and a second buffer structure can be selected, or a buffer component with only a first buffer structure can be selected, or a buffer component with only a second buffer structure can be selected.

[0069] The first structural layer 300 and / or the second structural layer 200 may have a concave-convex structure. For example, the first structural layer 300 may have a receiving groove 307, wherein the first region 310 may include the groove bottom surface of the receiving groove 307, and the second region 320 may include the groove side wall of the receiving groove 307. When the product 001 is packaged by the packaging structure, the groove bottom surface of the receiving groove 307 contacts the side of the product 001 facing the buffer component, so as to support the product 001, and the groove side wall of the receiving groove 307 is arranged opposite to the side wall of the product 001 (the edge of the side of the product 001 facing the buffer component) to limit the product 001. Of course, a first protrusion and a second protrusion may also be provided on the first structural layer 300, wherein the second protrusion protrudes from the top surface of the first protrusion, the first area 310 may include the first protrusion, and the second area 320 may include the second protrusion. The first protrusion may contact the side of the product 001 facing the buffer component to provide support, and the side wall of the second protrusion may be arranged opposite to the side wall of the product 001 to limit the product 001.

[0070] Furthermore, the first structural layer 300 and the second structural layer 200 can be sheet structures processed from sheet substrates, and the concave-convex structures thereon are correspondingly arranged, so as to adjust the rigidity of the sheet structure to ensure the optimization of the buffering effect in different directions. Taking the first structural layer 300 as an example, the first structural layer 300 has a first surface and a second surface opposite to each other, the concave area of ​​the first surface corresponds to the convex area of ​​the second surface, and the convex area of ​​the first surface is the concave area of ​​the second surface. The above-mentioned sheet structure can be a paper-plastic structure, or a structure processed by other processing methods.

[0071] In some embodiments, the third region 210 has a first cavity 201 opening toward the first structural layer 300, and the opening of the first cavity 201 can be closed by the first region 310 to form a first cavity 231 for buffering, and the first buffer structure includes at least one first cavity 231. In this embodiment, when the first structural layer 300 is connected to the second structural layer 200, the first structural layer 300 and the second structural layer 200 can be stacked together, so that the first region 310 corresponding to the third region 210 can cover the opening of the first cavity 201, thereby closing the opening of the first cavity 201 to form the first cavity 231 for buffering. That is, the inner wall of the first cavity 201 and the side of the first region 310 of the first structural layer 300 facing the second structural layer 200 can enclose the first cavity 231. When the buffer component is subjected to external force, the first cavity 231 can produce elastic or plastic deformation to reduce the external force transmitted to the product 001, thereby achieving a buffering effect. Since the first cavity 201 is located in the third area 210, the first cavity 231 corresponds to the first area 310 of the first structural layer 300 and the third area 210 of the second structural layer 200, thereby being able to effectively buffer the supported area of ​​the product 001 supported by the first area 310, and further buffer the product 001 as a whole.

[0072] The fourth region 220 may also have a second cavity 202 with an opening toward the first structural layer 300, and the opening of the second cavity 202 may be closed by the second region 320 to form a second cavity 232 for buffering, and the second buffer structure includes at least one second cavity 232. Similarly, when the first structural layer 300 is connected to the second structural layer 200, the first structural layer 300 and the second structural layer 200 may be stacked on each other, so that the second region 320 corresponding to the fourth region 220 may cover the opening of the second cavity 202, thereby closing the opening of the second cavity 202 to form a second cavity 232 for buffering. That is, the inner wall of the second cavity 202 and the side of the second region 320 of the first structural layer 300 facing the second structural layer 200 may enclose the second cavity 232. When the buffer assembly is subjected to external force, the second cavity 232 may produce elastic or plastic deformation to reduce the external force transmitted to the product 001, thereby achieving a buffering effect. Since the second cavity 232 is located in the fourth area 220, the first cavity 231 corresponds to the second area 320 of the first structural layer 300 and the fourth area 220 of the second structural layer 200, thereby being able to effectively buffer the contact area of ​​the product 001 that is limited by the second area 320, thereby buffering the entire product 001.

[0073] Of course, the first region 310 may also have a cavity opening toward the first structural layer 300, the opening of the cavity may be closed by the third region 210 to form a cavity for buffering, and the first buffer structure may include at least one of the above cavities. Alternatively, the second region 320 may have a cavity opening toward the first structural layer 300, the opening of the cavity may be closed by the fourth region 220 to form a cavity for buffering, and the second buffer structure may include at least one of the above cavities.

[0074] The distribution of the first cavity 201 and the second cavity 202 can be adjusted according to actual needs.

[0075] like Figure 7 As shown, in this embodiment, the first region 310 is a region located in the middle of the first structural layer 300, and the second region 320 is a "C"-shaped region arranged above, to the left, and below the first region 310. Fig.11 As shown, in contrast, the third region 210 is a region located in the middle of the second structural layer 200, and the fourth region 220 is a "C"-shaped region arranged above, to the left and below the third region 210. Figure 7 and Fig.11 The buffer assembly formed in the arrangement state can protect the left half of the product 001, and the right half of the product 001 can extend to the right side of the buffer assembly so as to be protected by another buffer assembly. The number of the first cavity 201 is multiple and they are arranged along the connecting edge of the third area 210 and the fourth area 220. Fig.11 As shown, a plurality of first cavities 201 are arranged along a "C"-shaped structure. A plurality of second cavities 202 are arranged along the shape of the fourth region 220. Fig.11 As shown, the plurality of second cavities 20 are arranged along a "C"-shaped structure.

[0076] The plurality of first cavities 201 may be relatively independent cavities, so that the first buffer structure includes a plurality of relatively independent first cavities 231. At least two of the plurality of first cavities 201 may also be connected, wherein the two connected first cavities 201 may be arranged adjacent to each other, or may be arranged with other structures (such as other first cavities 201) in between. The two connected first cavities 201 may be relatively connected via a connecting cavity, and the depth of the connecting cavity may be less than the depth of the first cavity 201. The above-mentioned depth direction is the arrangement direction along the two opposite surfaces of the second structural layer 200, that is, perpendicular to Fig.11Direction of the view shown. The two first cavities 201 may also be directly connected. Furthermore, the plurality of second cavities 202 may be relatively independent cavities, so that the second buffer structure includes a plurality of relatively independent second cavities 232. At least two of the plurality of second cavities 202 may also be connected, wherein the two connected second cavities 202 may be arranged adjacent to each other, or may be arranged with other structures (such as other second cavities 202) in between. The two connected second cavities 202 may be relatively connected via a connecting cavity, and the depth of the connecting cavity may be less than the depth of the second cavity 202. The above-mentioned depth direction is the arrangement direction along the two opposite surfaces of the second structural layer 200, that is, perpendicular to the Fig.11 The direction of the view shown. It is also possible to make the two second cavities 202 directly connected.

[0077] In order to improve the versatility of the packaging structure, the second cavity 202 can adjust the rigidity of the second region 320 by increasing or decreasing the filler therein. That is, by filling the second cavity 202 with fillers, the structural stability of the second cavity 202 can be improved. When the filler in the second region 320 is increased, the supporting effect of the filler on the inner wall of the second cavity 202 is also improved, thereby improving the structural stability of the second cavity 202 and further improving the rigidity of the second region 320; when the filler in the second region 320 is reduced, the supporting effect of the filler on the inner wall of the second cavity 202 is also reduced, thereby reducing the structural stability of the second cavity 202 and further reducing the rigidity of the second region 320. Among them, the filler can be a component made of environmentally friendly materials such as corrugated paper or honeycomb paperboard. The rigidity of the second region 320 can be adjusted according to the product 001 to meet the cushioning effect of different products 001, reducing the necessity of adjusting the mold (such as mold repair and mold modification) for making the cushioning component to meet the cushioning requirements of the product 001, thereby reducing costs. The second cavity 202 can be a columnar cavity or a long strip cavity, etc. The long strip cavity is particularly suitable for filling corrugated paper and honeycomb paperboard.

[0078] The first structural layer 300 has a first surface and a second surface opposite to each other; Figure 7 is the first surface of the first structural layer 300, Figure 8 It is the second surface of the first structural layer 300 .

[0079] The first surface is used to contact the product 001, and the second surface forms a recessed structure 306 that can at least partially accommodate the second structural layer 200. That is, during the process of combining the first structural layer 300 with the second structural layer 200, the second structural layer 200 is fully or partially embedded in the recessed structure 306 to achieve the connection between the first structural layer 300 and the second structural layer 200. The bottom surface of the groove of the recessed structure 306 can be in contact with the surface of the second structural layer 200 facing the first structural layer 300, and the side wall of the groove of the recessed structure 306 can be opposite to the side wall of the second structural layer 200, so as to limit the relative movement of the first structural layer 300 and the second structural layer 200.

[0080] In order to further improve the buffering effect, the second structural layer 200 has a cut-angle structure 203. That is, the connection between two adjacent side walls of the second structural layer 200 is disconnected to avoid the two adjacent side walls from being connected to each other to achieve the supporting effect. Through the above-mentioned cut-angle structure 203, the overall stiffness of the second structural layer 200 can be reduced, thereby further improving the buffering effect provided by the second structural layer 200 to the first structural layer 300. In addition, the cut-angle structure 203 can be at least partially embedded in the recessed structure 306 to meet the overall structural stability of the buffer component.

[0081] The cut corner side length of the cut corner structure 203 may be 45 mm to 80 mm, preferably, the cut corner side length is 60 mm. Fig.11 As shown, the above-mentioned cut-corner structure 203 is a right-angled triangle structure, and the length of its cut-corner side can be the length of the right-angled side of the right-angled triangle structure.

[0082] The number of buffer components is at least two; wherein the first structural layers 300 of the two buffer components can be arranged opposite to each other and respectively contact the first surface and the second surface of the product 001, and the first surface and the second surface are two opposite surfaces of the product 001. That is, the product 001 can be sandwiched between the two buffer components to provide opposite support effects on the two opposite surfaces of the product 001, thereby ensuring the support effect of the product 001 between the two buffer components.

[0083] by Figure 2 , Figure 4 and Figure 5 Taking the two buffer components arranged opposite to each other on the left side as an example, the first structural layers 300 of the two buffer components are opposite to each other and both have a receiving groove 307 (such as Figure 7 ). The upper left portion of the product 001 can be inserted into the receiving groove 307 of the upper left buffer assembly, and the first surface contacts the bottom surface of the receiving groove 307; the lower left portion of the product 001 can be inserted into the receiving groove 307 of the lower left buffer assembly, and the second surface contacts the bottom surface of the receiving groove 307. That is, the receiving grooves 307 of the two buffer assemblies are arranged opposite to each other to form a space for accommodating the left portion of the product 001.

[0084] In order to improve the structural stability, the second area 320 has a concave portion and a convex portion; when the first structural layers 300 of the two buffer components are arranged relative to each other, the concave portion of the second area 320 of one first structural layer 300 is arranged corresponding to the convex portion of the second area 320 of the other first structural layer 300. That is, when the first structural layers 300 of the above-mentioned two buffer components are relative to each other and clamped on the two surfaces (the first surface and the second surface) of the product 001, the second areas 320 of the first structural layers 300 of the two buffer components are relative to each other and the concave and convex parts match, thereby limiting the positions of the two buffer components and avoiding the two buffer components from being misaligned along the stacking direction perpendicular to the two components (such as Figure 5 The horizontal direction and Figure 6 Through the above arrangement, the overall wrapping of the packaging structure is enhanced, the close fit between the product 001 and the buffer component is ensured, and the safety and stability of the product 001 during transportation is further improved.

[0085] like Figure 5 , Figure 6 and Figure 7 As shown, the second area 320 at least includes a first recessed portion 302, a second recessed portion 304, a first convex portion 301 and a second convex portion 303. The first recessed portion 302 can be matched with the first convex portion 301, and the second recessed portion 304 can be matched with the second convex portion 303. The first recessed portion 302 can be matched with the first convex portion 301 to limit the misalignment of the two buffer components along the first direction (such as Figure 7 The second concave portion 304 can cooperate with the second convex portion 303 to limit the misalignment of the two buffer components along the second direction (such as Figure 7 in the horizontal direction).

[0086] There may be more than one first recessed portion 302, second recessed portion 304, first protruding portion 301 and second protruding portion 303. Preferably, the first recessed portion 302 corresponds to the first protruding portion 301 one by one, and the second recessed portion 304 corresponds to the second protruding portion 303 one by one. That is, when two buffer components are stacked, any first recessed portion 302 has only one first protruding portion 301 to match it, and any second recessed portion 304 has only one second protruding portion 303 to match it.

[0087] The above-mentioned multiple first recessed parts 302, multiple second recessed parts 304, multiple first protruding parts 301 or multiple second protruding parts 303 can be the same or different. Taking multiple first recessed parts 302 and multiple first protruding parts 301 matched therewith as an example for explanation, the structures of the multiple first recessed parts 302 can be the same, or the structures of at least two of the multiple first recessed parts 302 can be different, and the multiple first recessed parts 302 with the same structure are arranged at different positions of the second area 320 to play a corresponding role. For example, the first recessed portion 302 can be set to a "T"-shaped structure, an "L"-shaped structure, a "Y"-shaped structure, a "U"-shaped structure or an "N"-shaped structure, etc., and the above-mentioned settings can increase the number of groove side walls of the first recessed portion 302 and the different directions of the multiple groove side walls. The first protrusion 301 is a structure that corresponds to the first recessed portion 302, so that the first recessed portion 302 has multiple side walls that cooperate with different groove side walls, so that the first protrusion 301 and the first recessed portion 302 can play a role in limiting and supporting in multiple directions under the concave-convex cooperation between the first protrusion 301 and the first recessed portion 302. The two opposite groove side walls can position the first protrusion 301 that cooperates with the first recessed portion 302. The first protrusion 301 can be a cavity inside, such as the first protrusion 301 can be a structure formed on the reverse side of the cavity formed by the second region 320. When subjected to external force, the groove side wall of the first recessed portion 302 and the side wall of the first protrusion 301 are relatively squeezed and can play a buffering effect.

[0088] The first recessed portion 302 may also be configured as a square structure, a circular structure, a triangular structure, etc. The shape of the above structure is the projection shape of the first recessed portion 302 along the arrangement direction of the above two buffer components (such as two buffer components that can be clamped on two opposite surfaces of the product 001). Similarly, the second recessed portion 304 may also be configured as a "T"-shaped structure, an "L"-shaped structure, a "Y"-shaped structure, a "U"-shaped structure, or an "N"-shaped structure, etc., and may also be configured as a square structure, a circular structure, or a triangular structure, etc., and the second protrusion 303 is a structure that corresponds to and cooperates with the second recessed portion 304.

[0089] like Figure 7 As shown, the concave portion and the convex portion are symmetrically arranged on both sides of the first center line W of the buffer component; in the buffer components with two first structural layers 300 that can be arranged relatively, if one buffer component rotates 180° with the first center line W as the rotation axis, its placement state is the same as the placement state of the other buffer component. That is, the above two buffer components that can be stacked and have concave and convex limit fits can be processed by the same set of molds. Figure 4 and Figure 5Taking the two stacked buffer components on the left side as an example, one buffer component rotates 180° along the first center line W as the axis of rotation from its current placement state to the placement state of the other buffer component, and because the recessed portion and the raised portion are symmetrically arranged on both sides of the first center line W of the buffer component, the recessed portion and the raised portion on one buffer component are respectively located on both sides of the first center line W, while the raised portion and the recessed portion of the other buffer component are respectively located on both sides of the first center line W under the symmetry with the first center line W as the center, which makes the recessed portion on one buffer component correspond to the raised portion of the other buffer component, and the raised portion on one buffer component corresponds to the recessed portion of the other buffer component when the two buffer components are stacked, so that the structures of the two stacked buffer components can be the same, and the two stacked buffer components can meet the concave and convex limit fit. Since the structures of the two stacked buffer components can be the same, the types of molds for processing the buffer components can be reduced, the production process can be simplified, the cost can be further reduced, the optimization of mold opening can be achieved, the versatility of the buffer components can be improved, and the production and packaging efficiency can be improved, and the waste of resources can be reduced.

[0090] In some embodiments, the number of buffer components is at least two; wherein the first structural layers 300 of the two buffer components can respectively contact different areas of the first surface of the product 001. That is, the two buffer components can jointly support the same side (first surface) of the product 001, and by adjusting the spacing between the two buffer components, the buffering effect of products 001 of different lengths can be satisfied. Figure 4 The left and right buffer components shown in the figure take these two buffer components as an example. The length of product 001 ( Figure 4 When the horizontal direction in the middle is long, the distance between the left buffer component and the right buffer component can be adjusted, so as to facilitate the packaging of different products 001 while satisfying the wrapping property (support stability) of product 001.

[0091] In order to prevent the packaging structure from being impacted during the transportation of the product 001 and causing the buffer component to shift, the packaging structure also includes an intermediate buffer 400 disposed in the packaging box 100. Figure 4 When the first structural layer 300 of the left buffer component and the right buffer component in the middle (the middle buffer component) are in contact with different areas of the first surface of the product 001, the middle buffer component 400 is supported between the two buffer components. That is, the middle buffer component 400 has a supporting and limiting effect on the two buffer components, so as to prevent the relative position between the two buffer components from changing and affecting the buffering effect on the product 001.

[0092] Other structures such as cardboard or corrugated paper may also be used to connect the second structural layer 200 or the outer surface of the two buffer components to limit the relative positions of the two buffer components.

[0093] In some embodiments, the inner wall of the buffer assembly that contacts the intermediate buffer 400 has a first groove portion 305, and the intermediate buffer 400 has a second groove portion 401; when the buffer assembly contacts the intermediate buffer 400, the first groove portion 305 and the second groove portion 401 are arranged correspondingly. The corresponding arrangement of the first groove portion 305 and the second groove portion 401 can form a hollow structure to reduce the weight of the buffer assembly and the intermediate buffer 400, thereby reducing costs. In addition, since the first groove portion 305 and the second groove portion 401 are arranged correspondingly, a relatively stable structure (such as Figure 4 The oblong opening shown in the figure). Combined with the simulation test, it can be seen that Figure 4 The impact acceleration value of the structural surface shown is relatively large after being impacted, and the opening structure formed by the first groove portion 305 and the second groove portion 401 can reduce a part of the area, thereby improving the G value of the surface. The G value is the ratio of the acceleration to which the object is subjected to to the acceleration due to gravity.

[0094] Specifically, the first structure layer 300 of the buffer assembly has a first groove portion 305 , and the second structure layer 200 has a third groove portion 204 corresponding to the first groove portion 305 .

[0095] like Figure 1 and Figure 2 As shown, the packaging structure can have four groups of buffer components, which are located at the upper left, lower left, upper right and lower right of the product 001. Of course, the number of buffer components can also be increased or decreased according to the specific structure of the product 001, which will not be described in detail here. Therefore, two buffer components are symmetrically arranged on both sides of the middle buffer 400. Fig.15 , Fig.16 , Fig.17 and Fig.18 As shown, in some embodiments, the middle buffer 400 is symmetrically provided with second grooves 401 on both sides. The middle buffer 400 may have a middle support surface 410 for supporting the product 001 and a middle protrusion 420 for limiting the product 001, so as to provide a supporting and buffering effect for the middle part of the product 001 between the left and right buffer components.

[0096] The intermediate buffer 400 may be a single-layer structure. In order to improve the supporting effect of the intermediate buffer 400, the intermediate buffer 400 may have a concave-convex structure to improve the buffering effect of the intermediate buffer 400. For example, the intermediate buffer 400 has a groove structure 402 that is recessed away from the product 001. Of course, other concave-convex structures may also be provided, which will not be described in detail here and are all within the scope of protection.

[0097] The middle buffer may also have at least two structural layers, and a buffer area (such as a cavity, etc.) may be formed by two adjacent structural layers to provide buffer support for the middle portion of the product 001.

[0098] Furthermore, when the buffer assembly and the intermediate buffer member 400 are assembled with the product 001, the outer surface (the side facing away from the product 001) of the buffer assembly and the intermediate buffer member 400 can be flush. The outer surface can directly contact the inner wall of the packaging box 100, or a cushion layer (such as corrugated paperboard or honeycomb paperboard, etc.) can be arranged between the outer surface and the inner wall of the packaging box 100 to further enhance the buffering effect.

[0099] like Figure 1 and Figure 2 As shown, in some embodiments, the number of buffer components is four, which are respectively wrapped at the upper left, lower left, upper right and lower right of the product 001. In addition, an intermediate buffer 400 is arranged between the two buffer components wrapped at the upper left and upper right of the product 001, and an intermediate buffer 400 is arranged between the two buffer components wrapped at the lower left and lower right of the product 001. Through the above arrangement, the four buffer components and the two intermediate buffer components 400 form a structure that fully wraps the product 001, thereby improving the buffer protection effect of the product 001.

[0100] In some embodiments, the second structural layer 200 and / or the first structural layer 300 are formed by pulp molding. For example, the second structural layer 200 and / or the first structural layer 300 are paper-plastic structures formed by pulp molding, and can also be bamboo-plastic structures formed by bamboo pulp molding, etc. Among them, the first structural layer 300 and the second structural layer 200 can be processed by pulp molding. It is also possible to make only the first structural layer 300 molded by pulp, and the second structural layer 200 processed by other methods (such as cardboard folding, etc.). It is also possible to make the second structural layer 200 molded by pulp, and the first structural layer 300 processed by other methods (such as cardboard folding, etc.).

[0101] In other embodiments, the second structural layer 200 and / or the first structural layer 300 are formed by stamping of a sheet substrate. For example, a sheet substrate is made of an environmentally friendly material with high toughness, and the second structural layer 200 and / or the first structural layer 300 are formed by die stamping. Similarly, both the first structural layer 300 and the second structural layer 200 can be processed by stamping of a sheet substrate. It is also possible to make only the first structural layer 300 be stamped by a sheet substrate, and the second structural layer 200 be processed by other methods (such as cardboard folding or slurry molding). It is also possible to make the second structural layer 200 be stamped by a sheet substrate, and the first structural layer 300 be processed by other methods (such as cardboard folding or slurry molding).
