Detailed ways

Figure 1 is a schematic structural diagram of a packaging component during the applicant's research and development process. Referring to Figure 1, the packaging component includes two foams 100' arranged on opposite sides of the product to be protected 500. The two foams 100' are relatively separated and are not integrated and have no stability, and the two foams 100' are relatively separated. The separated foam 100' provides a limited buffer protection area for the product and cannot form a comprehensive protection. In addition, the fixation between the two separated foam 100' and the product relies on the outer layer of corrugated or cartons, corrugated and The cost of cartons is higher and there is a lot of room for improvement.

Based on the problems existing in the above-mentioned packaging components, the present disclosure provides a packaging component, aiming to solve, at least to a certain extent, the technical problems of unstable protection, inability to fully protect, and high cost of packaging components when transporting products to be protected. .

Figure 2 is a schematic diagram of a packaging assembly in accordance with some embodiments of the present disclosure. Referring to Figure 2, the packaging assembly is used for transportation protection of products to be protected. The packaging assembly includes a protective body 200. The protective body 200 can be wrapped on at least part of the outer surface of the product to be protected to form a protective layer to protect transportation. products in the process.

The protective body 200 includes more than three protective pieces 201 , one of which is fitted with two adjacent protective pieces 201 and supports the two adjacent protective pieces 201 , so that the protective body 200 can form a whole. type protective structure. During transportation, if a certain part of the protective body 200 (a certain protective piece 201) is subject to an impact force, the impact force can be dispersed to the remaining parts of the protective body 200 (the remaining protective pieces 201). other parts, thereby reducing the impact force of the product to be protected 500. If a certain part of the protective body 200 (a certain protective piece 201) is broken by the impact force, the remaining parts of the protective body 200 (the remaining protective parts 201) will cause damage to the broken part. It plays a supporting role to prevent the fractured part from shifting, so as to improve the comprehensive protection ability of the packaging components, and has very good practical value.

The material of the protective body 200 can be selected from common foam on the market. The two sides of each protective piece 201 can be fitted with the sides of two adjacent protective pieces 201. Since the sides of the protective piece 201 are used, The edges fit into each other, so that the protective piece 201 can be utilized to the greatest extent to form a protective layer that matches at least part of the outer surface of the product 500 to be protected, thereby saving costs.

Of course, in other embodiments, the adjacent protective parts 201 may not be fitted side-to-side, that is, the side edge of one protective part 201 may be fitted in the middle of another protective part 201, or it may be A matching protective layer is constructed to cover at least part of the outer surface of the product 500 to be protected. This solution will cause a waste of cost because there will be redundant protective pieces 201 that are not beneficial. However, this solution will extend the distance between the external collision object and the product 500 to be protected, which is more conducive to the protection of the product to be protected.

According to the appearance characteristics of the product 500 to be protected, the protective body 200 can be wrapped on the outer surface of a part of the product 500 to be protected, or can be wrapped on the entire outer surface of the product 500 to be protected. It can be set according to the specific shape of the product to be protected. . For example, some of the outer surfaces of the product to be protected (such as the back, top or bottom, etc.) do not need special protection. The protective body 200 does not need to be covered on these outer surfaces that do not need special protection. On the premise of achieving protection, it can also save money. cost; if the outer surface of the product 500 to be protected needs to be completely protected, the protective body 200 needs to be completely covered on these outer surfaces that do not require special protection to effectively protect the product 500 to be protected.

The product to be protected can be provided with a peripheral side. Correspondingly, a plurality of protective pieces 201 can enclose a protective cavity that matches the peripheral side and is used to accommodate the peripheral side. That is, the protective body 200 can only cover the peripheral side of the product to be protected. , to form a protective layer that only protects the peripheral side of the product to be protected.

Of course, the product 500 to be protected can also be provided with a top connected to the top of the peripheral side and a bottom connected to the bottom of the peripheral side. Correspondingly, multiple protective pieces 201 can enclose a protective cavity that matches the outer surface of the product to be protected, that is, a protective body. 200 can only cover the entire outer surface of the product 500 to be protected to form a protective layer that protects the entire outer surface of the product 500 to be protected.

The fitting between the protective pieces 201 in this disclosure means that the adjacent protective pieces 201 can be spliced into a detachable whole through their own insertion, mortise and tenon connection, etc. When the spliced protective body 200 forms an integral structure, it can cover the outer surface of the product 500 to be protected; when the integral structure is disassembled into each protective piece 201, the product 500 to be protected can be easily and quickly taken out. .

Specifically, both sides of the protective member 201 are connected with the sides of the adjacent protective member 201 by mortise and tenon to facilitate the assembly and disassembly of the protective body 200, so that the product 500 to be protected has better loading and unloading efficiency.

When transporting the product 500 to be protected, each protective piece 201 of the protective body 200 can be assembled on the outer peripheral surface of the product 500 to be protected, and then the various protective pieces 201 can be connected as a whole. In addition, the inner side of each protective piece 201 can match the shape of the covered part of the product 500 to be protected, and can effectively protect the product 500 to be protected, while the outer side of each protective piece 201 preferably forms a smoother surface. , an operating part for holding may be provided on the outer surface of the protective piece 201. The operating part may be hole-shaped or groove-shaped, and is not limited here.

Taking the product 500 to be protected as an oven as an example, the structure of the protective body 200 will be further described. Of course, the product 500 to be protected can also be electrical equipment such as a refrigerator or a washing machine, or an industrial product such as porcelain, which is not limited here. .

The oven is usually hexahedral, that is, it includes four peripheral sides connected in sequence along the circumferential direction, a top connecting the tops of the peripheral sides, and a bottom connecting the bottom ends of the peripheral sides. Referring to Figure 2, based on the oven described above, the protective body 200 includes two first protective parts 2011 and two second protective parts 2012. The two first protective parts 2011 relatively cover the parts extending in the first direction of the product 500 to be protected. On two sides, two second protective pieces 2012 are relatively covered on the two sides of the product 500 to be protected extending in the second direction, and the first direction and the second direction are different. That is, each protective piece 201 of the protective body 200 is connected in sequence around the peripheral side of the product 500 to be protected to form a vertically penetrating box structure, that is, the protective pieces 201 are only provided on the four sides of the oven.

Since the four sides of the perimeter of the oven are usually parallel in pairs, the first direction and the second direction are in a vertical relationship, that is, when the oven is placed on a horizontal plane, the first direction can be the X axis and the second direction can be the Y axis. axis. The two first protective pieces 2011 and the two second protective pieces 2012 are arranged opposite each other to cover and protect the peripheral side of the oven.

Of course, in other embodiments, if the four sides of the peripheral side of the product 500 to be protected are nearly relatively parallel, at this time, the first direction and the second direction may be in a nearly vertical relationship, that is, the first direction and the second direction There is a nearly vertical angle between them, and the angle can be 85°-95°. It can be specifically set according to the shape of the peripheral side of the product 500 to be protected, and is not limited here.

In order to prevent the top and bottom of the oven from impact, the top of the box structure may partially cover the top of the product to be protected, or/and the bottom of the box structure may partially cover the bottom of the product to be protected. That is to say, in order to cover the outer surface of the oven, each protective member 201 will be provided with a groove that matches the outer surface of the oven, so that the top of each protective member 201 covers part of the edge of the top of the oven, or/and each The bottom of the protective member 201 covers part of the edge of the bottom of the oven, so that the top of the box structure protrudes from the top of the oven, or/and the bottom of the box structure can protrude from the bottom of the oven, so that the top or/and the middle part of the bottom of the oven The outer surface is not covered by the protective piece 201, but it can be supported by the protective piece 201 on the side of the oven to keep a certain distance between the top and bottom of the oven and possible collision objects to reduce external collisions and impact objects. Risk of impact to the top and bottom of the oven to increase the reliability of the oven's transport protection.

Since the protective body 200 only protects the sides of the oven, only four protective pieces 201 are needed. Compared with the solution in which the protective pieces 201 are provided on the sides, top and bottom of the oven, this embodiment requires less protection. 201, accordingly, the manufacturing cost can be reduced.

Figure 3 is a schematic structural diagram of a first protective piece according to some embodiments of the present disclosure. Figure 4 is a schematic structural diagram of a second protective piece provided with a first tenon post according to some embodiments of the present disclosure. Figure 5 is a schematic structural diagram of a first protective piece according to some embodiments of the present disclosure. A schematic structural diagram of a second protective piece provided with a second tenon post according to some embodiments of the present disclosure. With reference to Figure 3, Figure 4 and Figure 5, the two first protective pieces 2011 can be disposed on the left and right sides of the oven respectively, that is, the first direction can be the front and rear direction, and the two second protective pieces 2012 can be disposed on the left and right sides of the oven respectively. The front and back sides, that is, the second direction can be the left and right directions, and the second direction is perpendicular to the first direction.

3, 4 and 5, each first protective piece 2011 is provided with more than one first mortise and tenon interface 202 on one side, and each second protective piece 2012 is provided with more than one second mortise interface on the other side. Mortise and tenon interface 203; correspondingly, among the two second protective parts 2012, one second protective part 2012 is provided with first mortise and tenon posts 204 on both sides, and the first mortise and tenon posts 204 on both sides are respectively connected with the two first protection parts. The first mortise and tenon interface 202 of the component 2011 corresponds to the mortise and tenon connection. The other second protective component 2012 is provided with second mortise and tenon posts 205 on both sides. The second mortise and tenon posts 205 on both sides are respectively connected with the two first protection components. The second mortise and tenon interface 203 of the component 2011 corresponds to the mortise and tenon connection.

Specifically, the side of the first protective member 2011 may be provided with an inwardly concave recess, which may be the above-mentioned mortise and tenon interface, and the side of the second protective member 2012 may be provided with an outwardly extending protrusion. The protruding part can be the above-mentioned mortise and tenon column, and the corresponding protruding part and the recessed part are fitted to realize the mortise and tenon connection between the mortise and tenon column and the corresponding mortise and tenon interface.

During implementation, first install the two first protective pieces 2011 on the left and right sides of the oven so that they fit closely with the oven. Since the two first protective pieces 2011 and the two first protective pieces 2011 have a mortise and tenon fit, , therefore, you can directly push the two second protective parts 2012 to the oven after aligning the mortise and tenon interfaces of the second protective part 2012 with the first protective part 2011. When the second protective piece 2012 is merged with the mortise and tenon interface of the first protective piece 2011, the two second protective pieces 2012 fit tightly with the oven, which is convenient and fast.

Further, the two first mortise and tenon interfaces 202 and the two second mortise and tenon interfaces 203 are arranged symmetrically to ensure symmetrical force. 203 are not at the same height. This is because, since the peripheral surface of the product 500 to be protected may have an irregular shape, correspondingly, the thickness of the protective member 201 where the first mortise-and-tenon interface 202 and the second mortise-and-tenon interface 203 are located is different. The first mortise and tenon interface 202 and the second mortise and tenon interface 203 are arranged at different heights of the protective member 201, which can ensure that the first mortise and tenon interface 202 and the second mortise and tenon interface 203 are at positions with different thicknesses. That is, the mortise and tenon interface is preferably provided on the thicker part of the protective piece 201. The mortise and tenon of the mortise and tenon interface on the thicker part of the protective piece 201 is stronger, which is more conducive to the integrity of the protective body 200; in addition, , the mortise and tenon interfaces at different heights can also be beneficial to the integrity of the protective body 200 and further improve the protective effect of the protective product 500 to be protected.

For the packaging assembly of the oven, the first mortise and tenon interface 202 can be provided in the middle of the side of the first protective member 2011, and the second mortise and tenon interface 203 can be provided at the upper part of the side of the first protective member 2011. This is Because: since the middle size of an oven or the like is thicker than the upper size, correspondingly, the thickness of the middle part of the first protective piece 2011 is smaller than the thickness of the upper part of the first protective piece 2011. The second mortise and tenon interface 203 located on the upper part of the first protective piece 2011 , the mortise and tenon of the second mortise and tenon column are strong, which is more conducive to the integrity of the protective body 200 and further improves the protective effect of the protective product 500 to be treated.

The packaging assembly provided by this disclosure connects multiple protective pieces 201 into an integral protective body 200 through overlapping tenon and tenon connections. During transportation, when any one of the foam pieces is subjected to an impact force, it can pass through The connection and contact parts disperse the impact force to other protective parts 201, thereby reducing the impact force on the oven. If any protective part 201 is broken by the impact force, other protective parts 201 also have a supporting effect on the broken protective part 201 to prevent The broken guard 201 is displaced. Therefore, compared with the existing protective structures with the same protection capabilities, the thickness of the overlapping mortise-and-tenon-connected packaging components will be reduced by about 50% while ensuring easy installation, which can significantly reduce the production cost and increase the amount of cabinets. , reducing shipping costs and having good economic value.

It should be noted that the first mortise and tenon interface 202 and the second mortise and tenon interface 203 can also be provided with more, such as three, four, etc., correspondingly, the first mortise and tenon column-204 and the second mortise and tenon column -205 can also be set to have more, such as three, four, etc., there is no limit here.

Further, a friction portion 206 for increasing friction is provided on the inner wall of the first mortise and tenon interface 202 and the second mortise and tenon interface 203. The friction portion 206 can be in a zigzag shape (as shown in Figure 6) or a wave shape ( As shown in Figure 7). Referring to FIG. 6 , the zigzag friction portion 206 can be composed of multiple triangles connected in sequence, and the triangle can be an isosceles triangle with a vertex angle of 120°. Referring to Figure 7, the wavy friction portion 206 can be composed of multiple protrusions connected in sequence. The protrusions can be a cubic sample of the two bottom corner points, two waist midpoints and the vertex of an isosceles triangle with a vertex angle of 120°. function curve.

Using the mortise and tenon interface with the friction part 206 can increase the active area of the mortise and tenon interface and increase the load-bearing capacity. At the same time, the only way for the mortise and tenon interface to come out is that the front and rear protective parts 201 can only come out first to enhance the fastening of the package. degree, further improving the integrity of the packaging and improving the protective effect.

Of course, the friction part 206 of the inner wall of the first mortise and tenon interface 202 and the second mortise and tenon interface 203 can also be in other shapes, and the friction part 206 may not be provided, that is, the first mortise and tenon interface 202 and the second mortise and tenon interface The inner wall of 203 is a flat surface, which is not limited here.

FIG. 8 is a schematic diagram of another packaging assembly according to some embodiments of the present disclosure. With reference to FIG. 8 , the protective body 200 of the packaging assembly also includes two third protection pieces in addition to the first protective piece 2011 and the second protective piece 2012 . Part 2013, two third protective parts 2013 are relatively covered on both sides of the vertical direction of the product 500 to be protected, that is, the two third protective parts 2013 are relatively covered on the top and bottom of the product 500 to be protected, The two sides of each third protective member 2013 in the first direction are respectively connected with the two sides of the two first protective members 2011 in the vertical direction. The two sides of each third protective member 2013 in the second direction are connected with each other by mortise and tenon. They are respectively connected with two sides of the two second protective parts 2012 in the vertical direction by mortise and tenon. That is, the protective body 200 can form an integral protective layer on the entire outer peripheral surface of the oven. Since the protective body 200 has an integral structure, during transportation, if a certain part of the protective body 200 is subjected to an impact force, it can The impact force is dispersed to other parts through the remaining parts of the protective body 200, thereby reducing the impact force on the product to be protected 500. If a certain part of the protective body 200 is broken by the impact force, the remaining parts of the protective body 200 will cause damage to the broken part. It has a supporting role and prevents the fractured part from shifting. It has the characteristics of good protection stability and comprehensive protection, so as to give full play to the comprehensive protection ability of the packaging components, and has very good practical value.

As for the assembly relationship between the third protective member 2013 and the first protective member 2011 and the second protective member 2012, reference may be made to the description of the mortise and tenon connection of the first protective member 2011 and the second protective member 2012, which will not be described again here.

It should be noted that since the protective body 200 itself is formed by the mortise and tenon connection of each protective piece 201, it can already provide all-round and stable protection for the product. At the same time, the protective body 200 formed by the mortise and tenon connection makes the packaging components and the product more secure. It can produce stable positioning, eliminate the use of external packaging, and significantly reduce packaging costs. When the external support body is eliminated, more matching mortise-and-tenon interfaces and mortise-and-tenon columns required for mortise-and-tenon connections can be provided to improve the reliability and stability of the protection.

In order to further reduce the cost, with reference to Figure 8, the protective body 200 can be provided with a hollow portion 207. There can be one hollow portion 207, or there can be multiple hollow portions, or each hollow portion 201 that constitutes the protective body 200 can be provided. Hollow portions 207 are provided on all of them, or hollow portions 207 can be provided on some of the protective pieces 201 constituting the protective body 200. Specifically, the hollow portions 207 can be adjusted according to the appearance and protection requirements of the product 500 to be protected. The hollow portion 207 can be an outwardly concave groove on the inside of the protective body 200, or/and an inwardly concave groove on the exterior of the protective body 200, or/and a through hole penetrating the protective body 200, etc. As for the hollow portion 207 The shape can be a square, a circle center, or other shapes, which are not limited here.

In some cases, the hollow portion 207 can be provided as an operating portion for transporting and assembling the protective member 201, so as to reasonably facilitate the structure of the protective body 200.

Figure 9 is a schematic diagram of the layout of the energy absorbing portion on the protective body. With reference to Figure 9, an energy absorbing portion 208 can be provided at the bottom corner of the protective body 200 to alleviate packaging tearing caused by the bottom collision impact of the product 500 to be protected. An energy-absorbing portion 208 may also be provided at the top corner of the protective body 200 to alleviate packaging tearing caused by the impact of the top of the product 500 to be protected.

It should be noted that it is preferable to only provide the energy absorbing part 208 at the corner of the bottom of the protective body 200, and the energy absorbing part 208 provided at the corner of the top of the protective body 200 is optional and can be rationalized according to actual needs. Setting options; In addition, the energy absorbing portion can be provided at one or a few corners of the protective body 200, or the energy absorbing portion 208 can be provided at all corners of the protective body 200. As for the specific installation quantity and installation area of the energy absorbing parts 208, rational installation selection can be made according to actual needs, and there is no restriction here.

For example: usually the protection of the side of the product 500 to be protected facing the operator (that is, the front of the product to be protected) is particularly important. Therefore, in the embodiment of the present application, the protective body 200 can only cover the side of the product 500 to be protected that faces the operator. An energy-absorbing part 208 is provided at the bottom or/and at the corner (as shown in Figure 9); for another example: a light-transmitting part is usually provided on the peripheral side of the product to be protected, and the light-transmitting part may be a glass window for observation. , or operation panel, etc. In this case, the energy-absorbing part 208 is provided on the side of the protective body 200 covering the light-transmitting part. For example, if the light-transmitting part is provided on the side of the product to be protected, the protective body 200 can only cover the transparent part. Energy absorbing portions 208 are provided at the corners of the top or/and bottom of the side of the light portion.

Since the two second protective parts 2012 are sandwiched between the two first protective parts 2011, the first protective part 2011 located on the outside is more likely to cause a collision impact. Therefore, in the embodiment of the present application, it is preferable to separate the energy absorbing part 208 and the absorbing part 2011. The energy portion 208 is provided at the bottom or/and top corner of the first protective member 2011 to improve the anti-collision impact capability of the protective body 200 .

Under normal circumstances, each energy-absorbing part 208 can be made of a material with a density higher than that of the protective member 201. The overall size of each energy-absorbing part will affect the protective capability of the energy-absorbing part. If the overall size of the energy-absorbing part is too small, it will This will lead to problems with the energy absorption effect. If the overall size of the corner protector 300 is too large, the support and protection effect on the protective body 200 will be weakened. Therefore, the selection of the material and size of the corner protector 300 needs to be studied.

Referring to FIG. 8 , the protective body 200 may have a notch 209 at the location where the energy-absorbing part 208 is provided. The corner protection 300 is received in the corresponding notch 209 , and the corner protection 300 is configured as the energy-absorbing part 208 .

As a preferred solution, the corner protectors 300 can be selectively and separately arranged in the corresponding missing corners 209. That is, when assembling the protective body 200, first assemble the bottom corner protector 300 in place, and then the product to be protected equipped with the protective body 200 will be assembled. 500 can be placed in place. If there is a top corner protector 300, the top corner protector 300 can be assembled on the protective body 200.

Of course, the corner protectors 300 can also be integrally molded, bonded or hot-melted, and placed in the corresponding missing corners 209, and also have the above-mentioned anti-collision and impact capabilities.

In related technologies, corner protectors are mostly made of hard materials. When an external collision object hits the corner protector, the hard material corner protector is likely to crush the foam of the packaging component, thereby causing technical problems such as damage to the protective product 500. The embodiment of the present application provides a corner protector with buffering and energy absorption.

The material of the corner protector 300 with buffering and energy absorption can be D3O material, honeycomb material with negative Poisson's ratio or local resonance metamaterial.

D3O material is a shear-thickening fluid that is a mixture of an oily liquid lubricant and a polymer suspended in it. When force is slowly applied to a shear-thickening fluid, the polymer chains have time to move and rearrange, so the viscosity is not affected. But if force is applied quickly, the polymer chains do not have time to rearrange and become tangled together, greatly increasing the viscosity. That is, when the corner protector 300 is impacted by a collision, the corner protector 300 made of D3O material can absorb the impact force of the collision. Compared with the hard corner protector 300, it can improve the situation in which the corner protector 300 crushes the internal protective body 200, and has better performance. energy absorption effect.

When the corner protector 300 is made of D3O material, you need to confirm the overall size of the corner protector 300. Since the overall size of the corner protector 300 cannot be too small, this will cause problems with the attenuation effect. If the overall size of the corner protector 300 cannot be too large, , will weaken the structure supporting the corner protector 300, so the size of the corner protector 300 is selected to be 70x30x30mm.

Similarly, the corner protector 300 containing negative Poisson's ratio honeycomb material can collapse and absorb local instantaneous large energy. When subjected to collision impact, the corner protector 300 can shrink. Compared with the hard corner protector 300, the corner protector 300 can be improved. When the internal protective body 200 is crushed, it has a better energy absorption effect.
