The applicant has found that cushioning packaging is an important component in the field of packaging, and the cushioning properties of the cushioning structure directly affect the safety and performance of the product to be protected during reliability tests such as transportation, vibration, dropping and the like. There are two main types of commonly used cushioning packages, namely, foam and paper cushioning packages, and foam has been widely used as a cushioning material due to its excellent cushioning property and shock absorption property, but the market application of foam has gradually moved to the end due to the increasing environmental pollution caused by the foam, especially the stricter restriction on the use of plastic in recent years. The paper cushion packaging is a cushion packaging which can be completely recycled or degraded, has higher environmental protection, but has poorer cushion performance and load-bearing performance due to the limitation of materials. Especially, many paper buffer packages in the market can not better meet the product protection requirement due to unreasonable structural design. In addition, compared with the foam plastic, the paper cushion packaging has one more folding forming processing procedure, most folding forming actions need manual operation, and the folding forming process of the paper cushion packaging has complex actions and needs multiple parts for assembly, so that the material and labor cost is high, and the application of the paper cushion packaging is limited to a great extent in the two aspects.

The hollow portions of the first wall portion and the second wall portion can cushion the packaged article in the first direction. The first protrusions of the first wall portion and the second wall portion protrude relative to the central plate, and can play a role in buffering the packaged articles along the second direction. One end of the first wall portion and one end of the second wall portion in the third direction are protruded relative to the third wall portion and the fourth wall portion, and the packaged product can be buffered in the third direction. In addition, the buffer structure is simple in structure by adopting one piece of paper, and is convenient to process and manufacture.

The hollow portion 121 of the first wall portion 12 can cushion the packaged article in the first direction Z. The tongue insertion portion 122 is inserted into the positioning insertion hole 111 of the center plate 11, so that the first wall portion 12 can be positioned perpendicular to the center plate 11, and the possibility of damage to the packaged article due to the first wall portion 12 being pressed by the rotation toward the center plate 11 is reduced. Furthermore, the first projection 123 projects with respect to the central plate 11 towards the side facing away from the hollow 121. The packaged article is placed on the side of the central plate 11 facing the hollow portion 121, and therefore the first protrusion 123 can support the packaged article in the second direction Y. The first wall portion 12 and the second wall portion 13 have the same structure, and are not described in detail here.

Because only need buckle just can form stable in structure, buffer structure that buffer capacity is strong, simplified the processing degree of difficulty of the buffer structure of this application embodiment, reduced the cost of manufacture.

Further, with continued reference to fig. 1 to 3, the hollow portion 121 includes an inner plate 125 and an outer plate 124 which are connected in a bending manner, one end of the outer plate 124 along the second direction Y is connected with the inner plate 125 in a bending manner through a first connecting plate 126, a part of the other end of the outer plate 124 along the second direction Y is connected with the central plate 11 in a bending manner, and the other part of the other end of the outer plate along the second direction Y is connected with the first protrusion 123; the outer plate 124, the first connecting plate 126, the inner plate 125 and the center plate 11 enclose a hollow space.

The inner plate 125, the outer plate 124 and a part of the central plate 11 enclose a hollow portion 121, both ends of the hollow portion 121 in the third direction X may not be closed, and the hollow portion 121 provides a cushion for the packaged article mainly through the inner plate 125 and the outer plate 124. The outer plate 124 and the inner plate 125 are connected by bending, and the bent inner plate 125 and the outer plate 124 may be parallel or non-parallel. The angle of the outer panel 124 with respect to the first direction Z may be determined according to the shape of the packing box, for example, the outer panel 124 is parallel to the side wall of the packing box. The angle of the inner plate 125 with respect to the first direction Z may be determined according to the shape of the packaged article, for example, the inner plate 125 is parallel to the side wall of the packaged article. The straight line where the outer plate 124 and the central plate 11 are connected is parallel to the third direction X, a part of the central plate 11 at the end of the outer plate 124 is bent and connected, and the other part extends along the outer plate 124 to form a first protrusion 123. During manufacturing, the shape of the first protrusion 123 may be cut in the corresponding area of the central plate 11, and when the outer plate 124 and the first protrusion 123 are formed by bending, the first protrusion 123 and the outer plate 124 are respectively located on two sides of the central plate 11 along the second direction Y.

Further, with continued reference to fig. 1-3, the inner panel 125 is parallel to the outer panel 124 and the third wall portion 14 abuts the outer panel 124. The inner plate 125 and the outer plate 124 are parallel to each other and perpendicular to the first direction Z, so that the hollow portion 121 can bear a force acting in the first direction Z to a greater extent, thereby improving the cushioning ability of the cushioning structure of the embodiment of the present application in the first direction Z. Further, since the third wall portion 14 abuts against the outer panel 124 and accordingly the fourth wall portion 15, the outer panel 124 can be maintained in a state perpendicular to the first direction Z, so that the stability of the first wall portion 12 is improved and the cushioning ability in the first direction Z of the cushioning structure of the embodiment of the present application is enhanced.

Since the first wall portion 12 and the second wall portion 13 have the same structure, the first wall portion 12, the second wall portion 13, the third wall portion 14, the fourth wall portion 15, and the central panel 11 can form a stable structure, so that the cushioning structure of the embodiment of the present application can have a certain structural strength to provide support and cushioning for the packaged article.

Further, with continuing reference to fig. 1 to 3, the third wall portion 14 includes a supporting plate 141, one end of the supporting plate 141 along the second direction Y is connected to the central plate 11 in a bending manner, and the supporting plate 141 is inserted into the first engaging groove 128; the supporting plate 141 includes a limiting protrusion 143 and an abdicating notch 142, the limiting protrusion 143 extends along the second direction Y and is located between the inner plate 125 and the outer plate 124, two ends of the limiting protrusion 143 along the first direction Z are respectively abutted against the inner plate 125 and the outer plate 124, and the abdicating notch 142 is a fan-shaped notch for abdicating the inner plate 125.

The supporting plate 141 is a main body of the third wall portion 14, and can prevent the third wall portion 14 from being easily deformed when being subjected to an external force, thereby ensuring a supporting effect of the third wall portion 14. The support plate 141 can be inserted into the first notch 128 to fix the relative positions of the first wall portion 12 and the third wall portion 14. When the cushion structure of the embodiment of the present application is manufactured, a paper forming process in the form of a folded paperboard structure is adopted, and the abdicating notch 142 is used for abdicating the inner plate 125 during the folding forming process. In the bending, the support plate 141 and the outer plate 124 may be first bent, and the inner plate 125 may be bent with respect to the outer plate 124. In this process, the supporting plate 141 needs to be inserted into the first engaging groove 128 first, and then the inner plate 125 is bent, so that the relief notch 142 enables the inner plate 125 to be bent smoothly until the inner plate 125 abuts against the limiting protrusion 143. At this time, the inner plate 125 and the outer plate 124 abut against both ends of the stopper projection 143 in the first direction Z, respectively. Therefore, the position-limiting protrusion 143 can further fix the relative positions of the inner plate 125 and the outer plate 124, so that the structure of the first wall portion 12 is more stable, and the cushioning ability of the cushioning structure of the embodiment of the present application in the first direction Z is further improved.

Further, with continued reference to fig. 1 to fig. 3, the third wall portion 14 further includes a second connecting plate 144, and the second connecting plate 144 is connected to one end of the supporting plate 141 along the first direction Z in a bending manner; the joint of the second connecting plate 144 and the supporting plate 141 is parallel to the second direction Y; the second connecting plate 144 is connected to the outer plate 124 by bending, the second connecting plate 144 is attached to the outer plate 124, and the joint between the second connecting plate 144 and the outer plate 124 is inclined in both the second direction Y and the third direction X.
