Description

Technical Field

[0001] This utility model relates to the field of packaging technology for protecting products, and in particular to a packaging structure and an electrical component having the packaging structure. Background Technology

[0002] Because EPS foam (polystyrene foam) is not easily degradable and damages the natural ecological environment, in order to solve the serious white pollution problem caused by EPS foam (polystyrene foam) as a cushioning liner in packaging structures, a new packaging structure uses a support liner formed by pulp molding as its cushioning liner. Compared with (polystyrene foam), the support liner formed by pulp molding is biodegradable and does not produce plastic residues that are difficult to decompose, thus avoiding the white pollution problem. It can also be recycled and reused, thereby reducing resource consumption and saving energy.

[0003] However, existing support pads formed by pulp molding only have a buffer arc surface to protect the product, resulting in a small buffer protection space and weak support structure strength, especially for heavy and large-volume products (such as water tanks of water heaters, cylindrical air conditioners, washing machines, refrigerators and other home appliances) where the buffer protection and support strength are insufficient. Summary of the Invention

[0004] To achieve the primary objective of this utility model, it provides a packaging structure that increases the buffer protection space, enhances the buffer protection capability of the product, strengthens the support structure, and improves the support protection capability of the product, thereby improving the buffer support protection effect of the product. Moreover, the packaging material is green and environmentally friendly, thus conforming to the concept of sustainable development.

[0005] To achieve the second objective of this utility model, this utility model provides an electrical component having the above-described packaging structure.

[0006] To achieve the primary objective of this utility model, it provides a packaging structure comprising an outer support shell and multiple inner cushioning pads, all located within the outer support shell. The outer support shell includes an end cover plate and a peripheral wall plate. The peripheral wall plate is disposed around the periphery of the end cover plate and forms a receiving cavity with the end cover plate. Both the peripheral wall plate and the end cover plate are made of cardboard. Each inner cushioning pad includes an arc-shaped plate, an inner side plate, and an outer side plate. The arc-shaped plate connects the inner side plate and the outer side plate, and the inner side plate abuts against the end cover plate. The inner side plate, with its supporting end away from the arc-shaped plate, abuts against the peripheral wall plate. The outer side plate is located at the opening of the receiving cavity away from the end cover plate, and the supporting end of the outer side plate, with its supporting end away from the arc-shaped plate, abuts against the peripheral wall plate. The arc-shaped plate is recessed towards the peripheral wall plate and has a supporting part. The supporting surface of the supporting part away from the arc-shaped plate abuts against the peripheral wall plate. The arc-shaped plates of the multiple inner cushions form a receiving cavity for accommodating the product. The end cover plate covers one end of the receiving cavity away from the outer side plate, and each inner cushion is integrally molded from pulp.

[0007] As can be seen from the above scheme, the packaging structure of this utility model places multiple inner cushioning pads within the receiving cavity formed by the end cover plate and the peripheral wall plate of the outer support shell. The end cover plate and the peripheral wall plate of the outer support shell provide structural support for the inner cushioning pads. Simultaneously, the arc-shaped plate of the inner cushioning pad connects the inner side plate and the outer side plate. The inner side plate abuts against the end cover plate, and the supporting end of the inner side plate away from the arc-shaped plate abuts against the peripheral wall plate. The outer side plate is located at the opening of the receiving cavity away from the end cover plate, and the supporting end of the outer side plate away from the arc-shaped plate abuts against the peripheral wall plate. Furthermore, the curved plate is recessed into the peripheral wall plate with a supporting part, the supporting surface of which abuts against the peripheral wall plate, thereby enhancing the support strength of the curved plate of the inner cushioning pad. Additionally, the arrangement of the outer and inner plates and the supporting part ensures sufficient buffering distance between the curved plate of the inner cushioning pad, which is adapted to the product, and the peripheral wall plate of the outer support shell, increasing the buffer protection space. Thus, the multiple curved plates of the inner cushioning pads form a cavity for accommodating the product, ensuring that the product is stably confined within the cavity of the packaging structure. Moreover, compared to EPS foam (polystyrene foam), this packaging structure uses cardboard to make the end caps and peripheral wall plates of the outer support shell, and uses pulp molding to integrally form each inner cushioning pad, all of which are biodegradable and recyclable, reducing environmental pollution and making it green and environmentally friendly.

[0008] Therefore, the packaging structure of this utility model can increase the buffer protection space, enhance the buffer protection capability of the product, and strengthen the support structure to improve the support protection capability of the product, thereby improving the buffer support protection effect of the product. Moreover, the packaging material is green and environmentally friendly, thus conforming to the concept of sustainable development.

[0009] A further embodiment involves forming a limiting groove between the arc-shaped plate, inner side plate, and outer side plate at the first end of the circumferential direction of each inner cushion in the receiving cavity, and having a first limiting plate protruding from the arc-shaped plate at the second end of the circumferential direction of each inner cushion in the receiving cavity, a second limiting plate protruding from the inner side plate at the second end of each inner cushion in the receiving cavity, and a third limiting plate protruding from the outer side plate at the second end of each inner cushion in the receiving cavity. The first, second, and third limiting plates are connected to form a limiting platform. In two adjacent inner cushions, the limiting platform of one inner cushion is inserted into the limiting groove of the other inner cushion.

[0010] A further solution is to position the support unit close to the limiting groove.

[0011] A further embodiment includes a peripheral side plate in each inner cushion, which is connected between the inner side plate and the outer side plate and is adjacent to the limiting platform. The peripheral side plate is also connected between the first limiting plate and the third limiting plate and abuts against the peripheral wall plate.

[0012] A further embodiment includes a reinforcing plate in each inner cushion, which is connected between the peripheral side plate, the first limiting plate, the second limiting plate and the third limiting plate, and the reinforcing plate is located at the convex end of the limiting platform away from the arc-shaped plate in the circumferential direction of the accommodating cavity.

[0013] A further option is to extend the support portion in the arcuate extension direction of the arcuate plate.

[0014] A further option is to have two support parts, one of which is located near the inner side plate and the other is located near the outer side plate.

[0015] A further option is to have the support located in the middle between the inner and outer side plates.

[0016] A further design involves both the end cap and the peripheral wall plate being quadrilateral in shape, with four inner cushions corresponding to the four corners of the outer support shell. The supporting end of one inner side plate abuts against two adjacent side walls of the peripheral wall plate, and the supporting end of one outer side plate abuts against two adjacent side walls of the peripheral wall plate. The supporting surface of one support part abuts against two adjacent side walls of the peripheral wall plate, or the supporting surface of one support part abuts against one side wall plate of the peripheral wall plate.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0031] First embodiment of packaging structure:

[0032] See Figures 1 to 6This embodiment discloses a packaging structure 10, including an outer support shell 11 and multiple inner cushions 12, all of which are located inside the outer support shell 11. The outer support shell 11 includes an end cover plate 111 and a peripheral wall plate 112. The peripheral wall plate 112 is disposed around the periphery of the end cover plate 111 and forms a receiving cavity (not shown) with the end cover plate 111. Both the peripheral wall plate 112 and the end cover plate 111 are made of cardboard. Furthermore, each inner cushion 12 includes an arc-shaped plate 121, an inner side plate 124, and an outer side plate 122. The arc-shaped plate 121 is connected between the inner side plate 124 and the outer side plate 122. The inner side plate 124 abuts against the end cover plate 111, and the supporting end of the inner side plate 124 away from the arc-shaped plate 121 abuts against the peripheral wall plate 112. The outer side plate 122 is located at the opening of the receiving cavity away from the end cover plate 111, and the supporting end of the outer side plate 122 away from the arc-shaped plate 121 abuts against the peripheral wall plate 112. The arc-shaped plate 121 is recessed towards the peripheral wall plate 112 and a support portion 123 is provided. The support surface 1231 of the support portion 123 away from the arc-shaped plate 121 abuts against the peripheral wall plate 112. Furthermore, the arc-shaped plates 121 of the multiple inner cushioning pads 12 form a receiving cavity 13 for accommodating the product, and an end cover plate 111 covers one end of the receiving cavity 13 away from the outer plate 122, and each inner cushioning pad 12 is integrally molded from pulp. Specifically, in this embodiment, the receiving cavity 13 formed by the arc-shaped plates 121 of the multiple inner cushioning pads 12 is fitted to the outer surface of the product.

[0033] In this embodiment, the packaging structure 10 places multiple inner cushioning pads 12 within the receiving cavity formed by the end cover plate 111 and the peripheral wall plate 112 of the outer support shell 11. The end cover plate 111 and the peripheral wall plate 112 of the outer support shell 11 provide structural support for the inner cushioning pads 12. Simultaneously, in this embodiment, the arc-shaped plate 121 of the inner cushioning pad 12 connects between the inner side plate 124 and the outer side plate 122. The inner side plate 124 abuts against the end cover plate 111, and the supporting end of the inner side plate 124 away from the arc-shaped plate 121 abuts against the peripheral wall plate 112. The outer side plate 122 is located at the opening of the receiving cavity away from the end cover plate 111, and the supporting end of the outer side plate 122 away from the arc-shaped plate 121 abuts against the peripheral wall plate 112. In addition, the arc-shaped plate 121 is recessed inward toward the peripheral wall plate 112 and a support portion 123 is provided. The support surface 1231 of the support portion 123 abuts against the peripheral wall plate 112, thereby enhancing the support strength of the arc-shaped plate 121 of the inner cushion 12. Furthermore, due to the arrangement of the outer side plate 122, the inner side plate 124 and the support portion 123, there is a sufficient buffer distance between the arc-shaped plate 121 of the inner cushion 12 that is adapted to the product and the peripheral wall plate 112 of the outer support shell 11, which can increase the buffer protection space. Thus, the arc-shaped plates 121 of the multiple inner cushions 12 form a receiving cavity 13 for accommodating the product, which can ensure that the product is stably confined within the receiving cavity 13 of the packaging structure 10. In addition, compared to EPS foam (polystyrene foam), the packaging structure 10 of this embodiment uses cardboard to make the end cap 111 and peripheral wall plate 112 of the outer support shell 11, and uses pulp molding to integrally form each inner cushion 12, which can be degraded and recycled, reducing environmental pollution and making it green and environmentally friendly.

[0034] Therefore, the packaging structure 10 in this embodiment can increase the buffer protection space, enhance the buffer protection capability of the product, and strengthen the support structure to improve the support protection capability of the product, thereby improving the buffer support protection effect of the product. Moreover, the packaging material is green and environmentally friendly, which is in line with the concept of sustainable development.

[0035] Specifically, in this embodiment, an indentation line is designed between the end cover plate 111 and the peripheral wall plate 112. The plate is folded around the indentation line and nailed or glued at the connection point to form the outer support shell 11 of this embodiment.

[0036] To improve the stability and reliability of the accommodating cavity 13 formed by the arcuate plates 121 of the multiple inner cushions 12 within the accommodating cavity of the outer support shell 11 for accommodating the product, in this embodiment, each inner cushion 12 forms a limiting groove 126 between the arcuate plate 121, inner side plate 124, and outer side plate 122 at the first end of the circumferential direction of the accommodating cavity 13 of each inner cushion 12. Furthermore, a first limiting plate 1252 protrudes from the arcuate plate 121 at the second end of the circumferential direction of the accommodating cavity 13 of each inner cushion 12, a second limiting plate 1253 protrudes from the inner side plate 124 at the second end of each inner cushion 12, and a third limiting plate 1251 protrudes from the outer side plate 122 at the second end of each inner cushion 12. The first limiting plate 1252, the second limiting plate 1253, and the third limiting plate 1251 are connected to form a limiting platform 125. Thus, in two adjacent inner cushions 12, the limiting platform 125 of one inner cushion 12 is inserted into the limiting groove 126 of the other inner cushion 12, so that the multiple inner cushions 12 in the receiving cavity of the outer support shell 11 are stably connected together in the circumferential direction of the receiving cavity 13, so as to avoid the dimensional deviation of the receiving cavity 13 for accommodating the product formed by the arc plates 121 of the multiple inner cushions 12.

[0037] To enhance the structural strength of the limiting platform 125, each inner cushion 12 in this embodiment further includes a peripheral side plate 128. The peripheral side plate 128 is connected between the inner side plate 124 and the outer side plate 122 and is disposed adjacent to the limiting platform 125. The peripheral side plate 128 is also connected between the first limiting plate 1252 and the third limiting plate 1251 and abuts against the peripheral wall plate 112. Furthermore, each inner cushion 12 in this embodiment also includes a reinforcing plate 127. The reinforcing plate 127 is connected between the peripheral side plate 128, the first limiting plate 1252, the second limiting plate 1253, and the third limiting plate 1251. The reinforcing plate 127 is located at the circumferentially convex end of the limiting platform 125 away from the arc-shaped plate 121 in the accommodating cavity 13, thereby further enhancing the structural strength of the limiting platform 125.

[0038] In order to improve the strength of the support structure on the side of the limiting groove 126, the support part 123 is set close to the limiting groove 126 in this embodiment.

[0039] Furthermore, in this embodiment, both the end cover plate 111 and the peripheral wall plate 112 are quadrilateral in shape. There are four inner cushioning pads 12, each corresponding to one of the four corners of the outer support shell 11. The supporting end of one inner side plate 124 abuts against two adjacent side walls of the peripheral wall plate 112, and the supporting end of one outer side plate 122 abuts against two adjacent side walls of the peripheral wall plate 112. Additionally, in this embodiment, the supporting surface 1231 of one supporting part 123 abuts against one side wall of the peripheral wall plate 112.

[0040] Second embodiment of packaging structure:

[0041] As an explanation of the second embodiment of the packaging structure of this utility model, the following description only focuses on the differences from the first embodiment of the packaging structure.

[0042] See Figures 7 to 9 In this embodiment, the support portion 123' extends in the arcuate extension direction of the arcuate plate 121. When both the end cover plate 111 and the peripheral wall plate 112 of the outer support shell 11 are quadrilateral, the support surface 1231' of one support portion 123' abuts against two adjacent side walls of the peripheral wall plate 112 of the outer support shell 11, further enhancing the strength of the support structure and further improving the support and protection capabilities for the product.

[0043] To further enhance the strength of the supporting structure, this embodiment has two support parts 123', one of which is located near the inner side plate 124 and the other is located near the outer side plate 122.

[0044] Third embodiment of packaging structure:

[0045] As an explanation of the third embodiment of the packaging structure of this utility model, the following description only focuses on the differences from the first embodiment of the packaging structure 10.

[0046] See Figures 10 to 12 In this embodiment, the support portion 123" extends in the arcuate extension direction of the arcuate plate 121. When both the end cover plate 111 and the peripheral wall plate 112 of the outer support shell 11 are quadrilateral, the support surface 1231" of one support portion 123" abuts against two adjacent side walls of the peripheral wall plate 112 of the outer support shell 11, further enhancing the strength of the support structure and further improving the support and protection capabilities for the product.

[0047] To further enhance the strength of the supporting structure, in this embodiment, the support portion 123 is located in the middle between the inner side plate 124 and the outer side plate 122.

[0048] The above embodiments are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles of this utility model patent application should be included within the scope of this utility model patent application.
