[0047] The application will be further described with reference to the drawings and specific examples. It is to be understood that the specific examples described herein are merely exemplary and that the application is not limited to these specific examples. In the following description, numerous specific details are discussed to provide a thorough and complete understanding of embodiments of the application.

[0048] AsFigure 1 and Figure 2 As shown in FIGS. 1, 2 and 3, the present disclosure provides a lower supporting structure 1, which can include a shell body 11 and a buffer structure 12. The shell body 11 has an inner part with a containing area and a buffer energy-absorbing area. The buffer energy-absorbing area is located at at least one corner area of the shell body 11. The containing area is located on a side of the side wall of the shell body 11 away from the buffer energy-absorbing area, and is configured to contain a structure to be packaged. The buffer structure 12 is arranged in the buffer energy-absorbing area, and the buffer structure 12 has a buffer energy-absorbing property.

[0049] It should be noted that, in the transportation process, the corner area in the lower supporting structure 1 is more likely to collide with the outside than other areas. The embodiments of the present disclosure are more conducive to reducing the impact force on the structure to be packaged contained in the lower supporting structure 1 when the lower supporting structure 1 is impacted by external force, so as to improve the buffering performance and shockproof performance of the lower supporting structure 1 on the structure to be packaged, and further to reduce the risk of damage to the structure to be packaged in the transportation process.

[0050] For example, the shell body 11 can have a plurality of corner areas, and a buffer energy-absorbing area is arranged on each corner area, so as to improve the buffering performance of the lower supporting structure 1 as a whole, reduce the impact force on the structure to be packaged contained in the lower supporting structure 1 when the lower supporting structure 1 is impacted by external force, and further to reduce the risk of damage to the structure to be packaged in the transportation process.

[0051] It should be noted that, when a buffer energy-absorbing area is arranged on each corner area, the shape and size of the buffer energy-absorbing area on each corner area can be the same, but are not limited thereto. The shape and size of the buffer energy-absorbing area on each corner area can be different, which can be set according to actual conditions.

[0052] As shown in FIGS. 1, 2 and 3, the present disclosure provides a lower supporting structure 1, which can include a shell body 11 and a buffer structure 12. The shell body 11 has an inner part with a containing area and a buffer energy-absorbing area. The buffer energy-absorbing area is located at at least one corner area of the shell body 11. The containing area is located on a side of the side wall of the shell body 11 away from the buffer energy-absorbing area, and is configured to contain a structure to be packaged. The buffer structure 12 is arranged in the buffer energy-absorbing area, and the buffer structure 12 has a buffer energy-absorbing property. Figure 1 and Figure 2 As shown in FIGS. 1, 2 and 3, the present disclosure provides a lower supporting structure 1, which can include a shell body 11 and a buffer structure 12. The shell body 11 has an inner part with a containing area and a buffer energy-absorbing area. The buffer energy-absorbing area is located at at least one corner area of the shell body 11. The containing area is located on a side of the side wall of the shell body 11 away from the buffer energy-absorbing area, and is configured to contain a structure to be packaged. The buffer structure 12 is arranged in the buffer energy-absorbing area, and the buffer structure 12 has a buffer energy-absorbing property.

[0053] For example, the shell body 11 in the embodiments of the present disclosure can be substantially a cuboid, and the two long sides of the shell body 11 can extend along the transverse direction X, the two short sides of the shell body 11 can extend along the longitudinal direction Y, and the height direction of the side wall of the shell body 11 can be parallel to the vertical direction Z. The shell body 11 can be provided with a plurality of first reinforcing ribs 111 on the two side walls of the long side, and the plurality of first reinforcing ribs 111 are arranged in the transverse direction X.

[0054] But not limited to this, the shell body 11 can also be provided with a plurality of first reinforcing ribs 111 on the two side walls on the short side, at this time, the plurality of first reinforcing ribs 111 can be arranged along the longitudinal direction Y.

[0055] Alternatively, the shell body 11 can also be provided with a plurality of first reinforcing ribs 111 on both the two long sides and the two short sides, which can be set according to actual conditions.

[0056] It should be noted that the interval arrangement in the above "a plurality of first reinforcing ribs 111 are arranged along the transverse direction X" can mean that the plurality of first reinforcing ribs 111 are uniformly arranged along the transverse direction X, that is, the plurality of first reinforcing ribs 111 are arranged at equal intervals. But not limited to this, the plurality of first reinforcing ribs 111 can also be arranged at unequal intervals, which can be set according to actual conditions. The interval arrangement in the following can be the same.

[0057] The shell body 11 of the shell body 11 is provided with a plurality of first reinforcing ribs 111 on the side wall, so as to improve the structural strength of the side wall of the shell body 11, reduce or avoid the deformation, bending or even damage of the side wall of the shell body 11 caused by the weak structural strength of the side wall of the shell body 11 when the user or the staff carries the lower supporting structure 1, so as to improve the transportation safety of the structure to be packaged and improve the durability of the lower supporting structure 1.

[0058] As shown in Figure 1 and Figure 2 In some embodiments, a plurality of second reinforcing ribs 112 are arranged on the region between at least two adjacent buffer structures 12, the plurality of second reinforcing ribs 112 are arranged at intervals along the extension direction of the side wall of the shell body 11, one end of the second reinforcing rib 112 abuts the inner side of the side wall of the shell body 11, and the other opposite end extends towards the accommodation area. The bottom surface of the second reinforcing rib 112 is connected with the bottom wall of the shell body 11.

[0059] For example, when the shell body 11 is a cuboid with two oppositely arranged long sides and two oppositely arranged short sides, the two long sides of the shell body 11 extend along the transverse direction X, the two short sides of the shell body 11 extend along the longitudinal direction Y, and the height direction of the side wall of the shell body 11 is parallel to the vertical direction Z, the second reinforcing rib 112 can be arranged on the region between the two adjacent buffer energy absorption areas on the long side of the shell body 11, at this time, the plurality of second reinforcing ribs 112 are arranged at intervals along the transverse direction X.

[0060] But not limited to this, the second reinforcing rib 112 in the embodiment of the present disclosure can also be arranged on the region between the two adjacent buffer energy absorption areas on the short side of the shell body 11, at this time, the plurality of second reinforcing ribs 112 are arranged at intervals along the longitudinal direction Y.

[0061] In addition, the second reinforcing ribs 112 in the embodiments of the present disclosure can also be arranged on the area between two adjacent buffer energy-absorbing zones on the long side and the short side of the shell body 11, which can be determined according to actual conditions.

[0062] It should be noted that the user or the staff usually carries the lower supporting structure 1 by lifting the side wall area of the shell body 11. When the shell body 11 contains the structure to be packaged, the weight of the containing area is large. In order to avoid the problems such as bending, deformation, and even damage of the shell body 11 on the area between two adjacent buffer structures 12 during the carrying process, the present application sets multiple second reinforcing ribs 112 arranged at intervals on the area between two adjacent buffer structures 12 to improve the structural strength of the side wall and the bottom wall of the shell body 11 on the area between the two adjacent buffer structures 12, thereby improving the transportation safety of the structure to be packaged and prolonging the service life of the lower supporting structure 1.

[0063] As shown in FIGS. 1 and 2, Figure 1 and Figure 2 In some embodiments, multiple first alignment grooves can be arranged on the area between at least two adjacent buffer structures 12, and the multiple first alignment grooves can be arranged at intervals along the extension direction of the side wall of the shell body 11.

[0064] For example, multiple first alignment beams 113 can be arranged in the area between two adjacent buffer structures 12, and the first alignment grooves are formed by surrounding the two adjacent first alignment beams 113. The two first alignment beams 113 located at opposite ends can be respectively in abutment with the two adjacent buffer structures 12.

[0065] As shown in FIGS. 1 and 2, Figures 2 to 4 The top surface of the first alignment beam 113 can be flush with the top surface of the side wall of the shell body 11, and the shell body 11 in the lower supporting structure 1 can form multiple protruding portions 114 arranged around the containing area. As shown in FIGS. 1 and 2, Figures 5 to 6 When multiple lower supporting structures 1 are stacked vertically upwards and downwards, at least part of the protruding portions 114 in the lower supporting structure 1 located above are in abutment with the buffer structures 12 in the lower supporting structure 1 located below. At this time, at least part of the protruding portions 114 in the lower supporting structure 1 located above are embedded in the first alignment grooves in the lower supporting structure 1 located below.

[0066] In some embodiments, one first reinforcing rib 111 and / or one second reinforcing rib 112 can be arranged in each first alignment groove.

[0067] The top surface of the first reinforcing rib 111 can be flush with the top surface of the buffer inner layer 121, so that when a plurality of lower support structures 1 are stacked vertically Z, the bottom surface of the protruding portion 114 located in the first positioning groove can abut against the top surface of the first reinforcing rib 111 in the corresponding first positioning groove, thereby enhancing the support performance of the lower support structure 1 located above and increasing the stacking balance.

[0068] As shown in Figure 1 and Figure 2 In some embodiments, the area between at least two adjacent buffer structures 12 is provided with a carrying groove 115, the groove opening of the carrying groove 115 is flush with the outer side surface of the side wall of the shell body 11, and the groove bottom of the carrying groove 115 is located on the side of the groove opening of the carrying groove 115 close to the accommodation area.

[0069] It should be noted that the outer side surface of the side wall of the shell body 11 refers to the surface of the side wall of the shell body 11 away from the buffer inner layer 121.

[0070] For example, the lower support structure 1 can be a rectangular body, the carrying grooves 115 can be located on the two short edges of the lower support structure 1, and the carrying grooves 115 can be located in the central area of the corresponding short edge to improve the stability of the lower support structure 1 during carrying. However, it is not limited thereto, and the carrying grooves 115 can also be located on the two long edges of the lower support structure 1, and the carrying grooves 115 can be located in the central area of the corresponding long edge. Alternatively, the carrying grooves 115 can be provided on both the two long edges and the two short edges of the lower support structure 1, which can be determined according to actual conditions.

[0071] The carrying grooves 115 are provided in the embodiments of the present disclosure to facilitate the grasping and carrying of the lower support structure 1 during transfer.

[0072] As shown in Figure 1 and Figure 2 In some embodiments, the buffer structure 12 can include a buffer inner layer 121 and a plurality of connecting portions 122. The buffer inner layer 121 is arranged opposite to and spaced apart from the two side walls constituting the corner in the shell body 11. The plurality of connecting portions 122 are arranged between the buffer inner layer 121 and the two side walls of the shell body 11 in the corner direction to separate the area formed between the buffer inner layer 121 and the two side walls of the shell body 11 into a plurality of buffer energy absorption cavities.

[0073] It should be noted that the buffer inner layer 121 can include two side walls, and the two side walls of the buffer inner layer 121 can correspond one-to-one to the two side walls constituting the corner in the shell body 11.

[0074] The two side walls of the buffer inner layer 121 can be arranged in parallel and spaced apart from the two side walls forming the corner in the shell body 11, but are not limited thereto. The two side walls of the buffer inner layer 121 can also be arranged in spaced apart from the shell body 11 while forming a certain angle between the two side walls forming the corner in the shell body 11. The specific arrangement can be set according to actual conditions.

[0075] In the embodiment of the present disclosure, the connecting portion 122 can be a connecting plate, a connecting rod or the like. The opposite ends of the connecting portion 122 are connected to the side wall of the buffer inner layer 121 and the shell body 11, respectively. In the embodiment of the present disclosure, the buffer structure 12 is arranged in the buffer and energy absorption area, so as to absorb the impact force transmitted from the shell body 11 to the to-be-packaged structure accommodated in the shell body 11 by the buffer structure 12. The buffer performance and the shock resistance of the lower supporting structure 1 to the to-be-packaged structure are improved, the risk of damage of the lower supporting structure 1 due to impact is reduced, and the overall structural strength of the lower supporting structure 1 is also enhanced, so as to improve the durability of the lower supporting structure 1.

[0076] In some embodiments, the side wall of the shell body 11 can be arranged to be inclined inward from top to bottom, that is, the side wall of the shell body 11 is arranged to be inclined from the top surface to the bottom surface of the shell body 11 towards the direction close to the accommodation area.

[0077] In the embodiment of the present disclosure, the area surrounded by the top surface of the side wall of the shell body 11 is larger than the area surrounded by the bottom surface of the side wall of the shell body 11. The to-be-packaged structure can be placed in the accommodation area conveniently, and the requirement for the alignment accuracy when the plurality of lower supporting structures 1 are stacked vertically is reduced, so as to improve the efficiency of the stacked arrangement of the plurality of lower supporting structures 1.

[0078] In some embodiments, the top surface of the buffer inner layer 121 and the top surface of the connecting portion 122 can be lower than the top surface of the side wall of the shell body 11. When the plurality of lower supporting structures 1 are arranged vertically and stacked, the bottom surface of the side wall of the lower supporting structure 1 located at the upper position is in abutment with the buffer structure 12. That is, when the plurality of lower supporting structures 1 are stacked vertically, the bottom surface of the side wall of the shell body 11 in the lower supporting structure 1 located at the upper position is lower than the top surface of the side wall of the shell body 11 in the lower supporting structure 1 located at the lower position. Therefore, the occupied height in the vertical direction Z when the plurality of lower supporting structures 1 are stacked can be reduced, and the transportation and storage space of the lower supporting structure 1 can be saved, so as to realize the lean management of the lower supporting structure 1.

[0079] In some embodiments, the buffer inner layer 121 has a corner point, and the corner point of the buffer inner layer 121 corresponds to the corner point of the shell body 11. The plurality of connecting portions 122 include a corner connecting piece 123. One end of the corner connecting piece 123 is connected to the corner point of the buffer inner layer 121, and the other end is connected to the corner point of the shell body 11.

[0080] It is to be noted that the inflection point refers to the turning point of the two side walls constituting the corner. The turning point of the two side walls constituting the corner in the shell body 11 is the inflection point of the corner region. The cushion inner layer 121 is arranged opposite and spaced apart from the two side walls constituting the corner in the shell body 11, and therefore the cushion inner layer 121 can form an inflection point at the position corresponding to the inflection point of the shell body 11.

[0081] In the embodiments of the present disclosure, the inflection point connecting piece 123 is arranged in the cushion energy absorption area, and the opposite ends of the inflection point connecting piece 123 are connected to the inflection points of the shell body 11 and the cushion inner layer 121 respectively, so as to strengthen the structural strength of the shell body 11 and the cushion inner layer 121 at the inflection points, and reduce the risk of damage of the shell body 11 and the cushion inner layer 121 at the inflection points when the lower supporting structure 1 is impacted by external force, thereby prolonging the service life of the lower supporting structure 1.

[0082] In some embodiments, the top surface of the end of the inflection point connecting piece 123 connected to the cushion inner layer 121 can be flush with the top surface of the cushion inner layer 121, the top surface of the end of the inflection point connecting piece 123 connected to the shell body 11 can be higher than the top surface of the cushion inner layer 121, and the top surface of the end of the inflection point connecting piece 123 connected to the shell body 11 can be lower than the top surface of the side wall of the shell body 11.

[0083] When the plurality of lower supporting structures 1 are stacked vertically upward and downward along the vertical direction Z, the bottom surface of the side wall of the shell body 11 in the lower supporting structure 1 located above is lower than the top surface of the side wall of the shell body 11 in the lower supporting structure 1 located below, because the top surface of the end of the inflection point connecting piece 123 connected to the shell body 11 is lower than the top surface of the side wall of the shell body 11, thereby reducing the occupied height in the vertical direction Z when the plurality of lower supporting structures 1 are stacked upward and downward. Meanwhile, the top surface of the end of the inflection point connecting piece 123 connected to the shell body 11 is higher than the top surface of the cushion inner layer 121, thereby increasing the connection area between the connecting part 122 and the shell body 11, so as to strengthen the supporting performance of the inflection point connecting piece 123 to the shell body 11.

[0084] As shown in FIGS. 1, 2 and 3, Figure 1 and Figure 2 In some embodiments, the lower supporting structure 1 can include a supporting piece arranged in the accommodating area, and the supporting piece has an arc-shaped supporting surface 131 for receiving the structure to be packaged, and the shape of the arc-shaped supporting surface 131 is adapted to the shape of the structure to be packaged.

[0085] For example, the structure to be packaged in the embodiments of the present disclosure can be a curved display 4, as shown in FIG. 4. Figure 7 The shape of the arc-shaped supporting surface 131 in the supporting piece can be adapted to the shape of the display surface of the curved display 4, and when the curved display 4 is placed in the lower supporting structure 1, the arc-shaped supporting surface 131 can completely fit the display surface of the curved display 4, thereby strengthening the supporting performance of the supporting piece to the structure to be packaged.

[0086] In some embodiments, the support is connected with the cushion inner layer 121.

[0087] Specifically, the support is connected with the inner side of the cushion inner layer 121 away from the shell main body 11.

[0088] In the embodiments of the present disclosure, at the connection between the support and the cushion inner layer 121, the arc-shaped support surface 131 is lower than the top surface of the cushion inner layer 121, so that when the structure to be packaged is placed in the accommodation area, the cushion structure 12 can abut against at least part of the side surface of the structure to be packaged, so that the impact force of the external environment on the structure to be packaged can be effectively absorbed by the cushion structure 12, thereby reducing the risk of damage to the structure to be packaged.

[0089] Of course, in order to improve the protection performance of the lower supporting structure 1 on the structure to be packaged, the height difference between the arc-shaped support surface 131 and the top surface of the corresponding cushion inner layer 121 in the embodiments of the present disclosure can be greater than or equal to the thickness of the structure to be packaged, so that when the structure to be packaged is placed in the accommodation area, the side surface of the structure to be packaged is completely abutted against the cushion inner layer 121.

[0090] As Figure 1 and Figure 2 In some embodiments, the side of the support close to the cushion inner layer 121 can be provided with a first avoiding groove 132, and the groove top of the first avoiding groove 132 is higher than the groove bottom. The first avoiding groove 132 can extend around the outer side wall of the support.

[0091] For example, the first avoiding groove 132 in the embodiments of the present disclosure can be a groove structure formed between the support and the cushion inner layer 121, the groove top of the first avoiding groove 132 is flush with the arc-shaped support surface 131, and the groove bottom of the first avoiding groove 132 is lower than the arc-shaped support surface 131.

[0092] It should be noted that the dihedral angle formed between the front surface of the structure to be packaged in contact with the arc-shaped support surface 131 and the side surface of the structure to be packaged in contact with the cushion inner layer 121 is prone to scratching with the arc-shaped support surface 131 and the cushion inner layer 121 at the corresponding positions during the carrying process, the lower supporting structure 1 is worn, and debris is generated.

[0093] The embodiments of the present disclosure can reduce the contact area between the lower supporting structure 1 and the two-angle formed between the front and side of the to-be-packaged structure, reduce the friction between the lower supporting structure 1 and the to-be-packaged structure during the carrying process, thereby reducing the wear of the lower supporting structure 1 and the to-be-packaged structure, and reducing the debris generated by the friction of the lower supporting structure 1, thereby reducing the problem of the to-be-packaged structure being contaminated by the debris, and improving the user's unpacking experience. When the to-be-packaged structure is a display, the debris generated by the lower supporting structure 1 can also reduce the problem of entering the display and causing poor display effect of the display.

[0094] As shown in Figure 1 and Figure 2 In some embodiments, the support is hollow inside, and the support and the bottom wall of the shell body 11 form a containing groove, at this time, the area of the arc-shaped supporting surface 131 is smaller than the front of the to-be-packaged structure, and the support can also reduce the contact area between the arc-shaped supporting surface 131 and the to-be-packaged structure while supporting the to-be-packaged structure, so as to reduce the friction between the to-be-packaged structure and the support.

[0095] In the embodiments of the present disclosure, at least one first reinforcing piece 133 can be arranged in the containing groove, the first reinforcing piece 133 is located in the middle of the containing groove, and the bottom surface of the first reinforcing piece 133 is connected with the bottom wall of the shell body 11, and the opposite ends of the first reinforcing piece 133 abut against the inner side surface of the support. The top surface of the first reinforcing piece 133 is lower than the corresponding arc-shaped supporting surface 131.

[0096] For example, when the bottom surface of the containing groove is a rectangle, the first reinforcing piece 133 can extend along the short edge direction of the bottom surface of the containing groove. When one first reinforcing piece 133 is arranged in the containing groove, the central axis of the first reinforcing piece 133 coincides with the central axis of the long edge of the bottom surface of the containing groove. When more than two first reinforcing pieces 133 are arranged in the containing groove, the first reinforcing pieces 133 are uniformly spaced in the middle of the containing groove, and the first reinforcing pieces 133 are arrayed along the long edge direction of the bottom surface of the containing groove. However, the first reinforcing piece 133 in the embodiments of the present disclosure can also extend along the long edge direction of the bottom surface of the containing groove, which can be set according to actual conditions.

[0097] The embodiments of the present disclosure can arrange the first reinforcing piece 133 in the containing groove to improve the overall structural strength of the lower supporting structure 1 and reduce the possibility of bending deformation of the lower supporting structure 1 at the position of the containing groove during the carrying process.

[0098] Further, the embodiments of the present disclosure can also open a pull-through groove 136 on the first reinforcing piece 133, and the pull-through groove 136 can be located in the middle of the first reinforcing piece 133 to effectively increase the strength of the first reinforcing piece 133 and reduce the risk of bending of the first reinforcing piece 133 under stress.

[0099] In some embodiments, at least one second reinforcing member 134 can be arranged in the accommodating groove, the second reinforcing member 134 is arranged at a corner of the accommodating groove, and the bottom surface of the second reinforcing member 134 is connected with the bottom surface of the shell body 11, and the two opposite side surfaces of the second reinforcing member 134 are respectively connected with the two inner side surfaces of the support member corresponding to the corner.

[0100] Specifically, the second reinforcing member 134 in the embodiment of the present disclosure can be a diagonal brace arranged at the corner of the accommodating groove, the second reinforcing member 134 is installed on the bottom wall of the shell body 11, and the two opposite side surfaces of the second reinforcing member 134 are respectively abutted on the two inner side surfaces of the support member corresponding to the corner.

[0101] The embodiment of the present disclosure can improve the overall structural strength of the lower supporting structure 1 by arranging the second reinforcing member 134, and reduce the possibility of bending deformation of the lower supporting structure 1 at the position of the accommodating groove, so as to improve the supporting performance of the support member to the structure to be packaged.

[0102] In some embodiments, a third reinforcing member 135 can also be arranged in the accommodating groove, the third reinforcing member 135 is arranged on at least one inner side surface of the support member, wherein the third reinforcing member 135 can be located at the middle part of the corresponding inner side surface of the support member, and one surface of the third reinforcing member 135 is connected with the corresponding inner side surface of the support member, and the other surface is connected with the bottom wall of the shell body 11. That is, the third reinforcing member 135 supports the bottom wall of the shell body 11 and the inner side surface of the support frame, so as to strengthen the structural strength of the lower supporting structure 1, reduce the possibility of bending deformation of the lower supporting structure 1 at the position of the accommodating groove, and improve the supporting performance of the support member to the structure to be packaged.

[0103] In some embodiments, an arrow mark can also be arranged on the bottom wall of the shell body 11, so as to facilitate the production line to identify the operation direction and avoid repeated operation caused by misplacement of the structure to be packaged.

[0104] For example, when the structure to be packaged is placed in the lower supporting structure 1, the upper part of the structure to be packaged can be located in the direction indicated by the arrow.

[0105] In the embodiment of the present disclosure, the upper supporting structure 2 can be made of paper-plastic material, which can realize 100% recyclable utilization of the lower supporting structure 1, reduce the manufacturing cost and tax fee of recycling processing of the lower supporting structure 1, and also make the lower supporting structure 1 meet the green and environmental protection packaging laws and regulations in Europe, America, Japan and Korea, so as to expand the application market of the lower supporting structure 1 and improve the practicability of the lower supporting structure 1.

[0106] In some embodiments, the lower supporting structure 1 can be an integrated structure.

[0107] Specifically, the lower supporting structure 1 in the embodiments of the present disclosure can be integrally compression-formed by a mechanical device, and has an elegant, simple, and generous appearance. Compared with the lower supporting structure 1 formed by manual assembly and folding, the lower supporting structure 1 in the present disclosure can simplify the manual operation process of the lower supporting structure 1, thereby reducing the labor cost.

[0108] As shown in Figure 1 , Figure 8 , Figure 9 , the present disclosure provides a cushioning package 3, which can include an upper supporting structure 2 and any of the lower supporting structures 1 as described above.

[0109] As shown in Figures 9 to 12 , the upper supporting structure 2 can include a containing area and a positioning area arranged around the containing area, and a plurality of protruding structures 21 are arranged on the positioning area. At least part of the protruding structures 21 in the upper supporting structure 2 can be used for positioning with the first positioning groove.

[0110] In the embodiments of the present disclosure, when the upper supporting structure 2 is arranged in the box with the lower supporting structure 1, the upper supporting structure 2 is arranged vertically above the lower supporting structure 1, and the bottom surface of the protruding structure 21 is lower than the top surface of the side wall of the shell main body 11.

[0111] Specifically, when the upper supporting structure 2 is arranged in the box with the lower supporting structure 1, the bottom surface of the protruding structure 21 can be completely arranged in the space formed by the side wall of the lower supporting structure 1, and the bottom surface of at least part of the protruding structure 21 is in abutment with the cushioning structure 12.

[0112] The bottom surface of the upper supporting structure 2 forms an arc-shaped supporting surface in the containing area, and the shape of the arc-shaped supporting surface is adapted to the shape of the structure to be packaged. That is, when the structure to be packaged is arranged in the cushioning package 3, the arc-shaped supporting surface can be in close contact with the back surface of the structure to be packaged away from the lower supporting structure 1, thereby reducing the shaking of the structure to be packaged in the cushioning package 3, reducing the risk of friction and collision between the structure to be packaged and the cushioning package 3, and improving the protection performance of the cushioning package 3 on the structure to be packaged.

[0113] As shown in Figure 9 and Figure 12 , in some embodiments, two mounting grooves 22 can also be arranged on the upper supporting structure 2.

[0114] It should be noted that when the structure to be packaged is a display, the structure to be packaged is usually also provided with a base structure 6 and a support structure 5, as shown in Figure 13 , the base structure 6 and the support structure 5 are respectively mounted in the two mounting grooves 22.

[0115] The mounting groove 22 can be located on the side of the upper supporting structure 2 away from the lower supporting structure 1, so as to avoid the risk of friction and collision between the base and the support and the structure to be packaged.

[0116] The embodiments of the present disclosure realize the maximum utilization of the space of the upper supporting structure 2 by setting two installation grooves 22 on the upper supporting structure 2, rationally setting the installation grooves 22 of the placing support and the base by using the characteristics of the structure of the structure to be packaged, achieving the purpose of protecting the product, and at the same time, achieving a more reasonable package size and maximizing the loading and transportation efficiency. That is, the upper supporting structure 2 of the present disclosure can achieve a smaller packaging specification and a larger cabinet loading capacity, reduce the overall space occupied by the packaging structure, and achieve the purposes of reducing the packaging cost and reducing the transportation and storage cost.

[0117] In some embodiments, the upper supporting structure 2 can include a buffer housing 23, the buffer housing 23 including a bottom plate and a side plate arranged around the bottom plate, the bottom plate and the side plate surrounding to form a containing space. Wherein, the containing space is located on the side of the buffer housing 23 away from the lower supporting structure 1.

[0118] In the embodiments of the present disclosure, a plurality of third reinforcing ribs 24 can be arranged in the containing space, the plurality of third reinforcing ribs 24 can extend along the extension direction of the side plate, the third reinforcing rib 24 is connected with the side plate, and the third reinforcing rib 24 extends along the height direction of the side plate. The embodiments of the present disclosure set the third reinforcing rib 24 to improve the structural strength of the buffer housing 23 and reduce the problems of deformation, bending and the like of the upper supporting structure 2.

[0119] In some embodiments, a second avoiding groove is formed between the accommodating area and the alignment area, the second avoiding groove is located on the side of the buffer housing 23 close to the lower supporting structure 1, and the groove opening of the second avoiding groove is lower than the groove bottom.

When the structure to be packaged is a display, it can also reduce the problem that the debris generated by the lower supporting structure 1 enters the display and causes poor display effect of the display.

[0121] In some embodiments, a plurality of second alignment beams 25 can be arranged in the buffer space, and a second alignment groove is formed between adjacent two second alignment beams 25. Figure 14 and Figure 15 As shown in FIGS. 5 and 6, when a plurality of upper supporting structures 2 are stacked vertically, the protruding structure 21 in the upper supporting structure 2 located at the upper side is embedded in the second alignment groove, thereby reducing the occupied space when a plurality of upper supporting structures 2 are vertically stacked.

The vertical Z height of a set of EVA is 195mm, and each additional set of EVA increases the vertical Z height by 195mm. Taking ten sets of cushioning packages 3 in storage as an example, the vertical stacking height of ten sets of cushioning packages 3 in the present disclosure is 1265mm, occupying 0.55m3 of warehouse space. The vertical stacking height of ten sets of EVA is 1950mm, occupying 0.79m3 of warehouse space. The vertical height difference between ten sets of cushioning packages 3 in the present disclosure and ten sets of EVA in storage is 685mm, and the space utilization rate is optimized by 30.37%. The more the number of cushioning packages 3 stacked vertically in the vertical Z direction, the more obvious the storage saving benefit.

[0125] In some embodiments, a third reinforcing rib 24 can be arranged in each second positioning slot. When a plurality of upper supporting structures 2 are vertically stacked, the bottom surface of the protruding structure 21 in the upper supporting structure 2 above abuts against the top surface of the third reinforcing rib 24 in the upper supporting structure 2 below. When a plurality of cushioning packages 3 are vertically stacked, the bottom surface of the protruding portion 114 in the upper supporting structure 1 above abuts against the top surface of the third reinforcing rib 24 in the upper supporting structure 2 below.

[0126] In some embodiments, an arrow mark can be arranged on the side of the cushioning shell 23 away from the lower supporting structure 1, to facilitate the production line to identify the operation direction and avoid repeated operations caused by misplacement of the to-be-packaged structure.

[0127] For example, when the to-be-packaged structure is placed in the cushioning package 3, the upper part of the to-be-packaged structure is in the direction indicated by the arrow of the upper supporting structure 2.

[0128] When the upper supporting structure 2 and the lower supporting structure 1 are both provided with arrow marks, the direction of the arrow in the upper supporting structure 2 can be the same as the direction of the arrow in the lower supporting structure 1.

Then, the upper supporting structure 2 is arranged in the box with the lower supporting structure 1, and when the upper supporting structure 2 is arranged in the box, the direction of the arrow in the upper supporting structure 2 is the same as the direction of the arrow in the lower supporting structure 1. After the upper supporting structure 2 and the lower supporting structure 1 are arranged in the box, the base and the support are placed in the corresponding mounting groove 22. Finally, the buffer packaging 3 containing the to-be-packaged structure can be placed in the adaptive outer packaging box as a whole.
