The application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

FIG. 1 is a schematic view of a package assembly during the development of the applicant. In connection with fig. 1, the package assembly includes two foams 100 'disposed on opposite sides of a product 500 to be protected, the two foams 100' are disposed in a relatively separated manner, without being integrated, without stability, and the two separated foams 100 'provide limited cushioning protection areas for the product, without forming a complete protection, and the fixation between the two separated foams 100' and the product depends on the corrugated or cardboard box covered by the outer layer, which has high cost and a large improvement space.

Based on the problems of the packaging assembly, the embodiment of the application provides a packaging assembly, which aims to at least solve the technical problems of unstable protection, incapability of comprehensive protection and higher cost of the packaging assembly when the product 500 to be protected is transported.

Fig. 2 is a schematic view of a package assembly according to an embodiment of the present application. Referring to fig. 2, the package assembly according to the embodiment of the present application is used for transportation protection of a product to be protected, and the package assembly includes a protecting body 200, and the protecting body 200 may be coated on at least a portion of an outer surface of the product to be protected to form a protecting layer for protecting the product during transportation.

The protective body 200 according to the embodiment of the application includes more than three protective pieces 201, wherein one protective piece 201 is embedded with two adjacent protective pieces 201 and supports the two adjacent protective pieces 201, so that the protective body 200 can form an integral protective structure, in the transportation process, if a certain part (a certain protective piece 201) of the protective body 200 receives impact force, the impact force can be dispersed to other parts through other parts (other protective pieces 201) of the protective body 200, so that the impact force of a product 500 to be protected is reduced, if a certain part (a certain protective piece 201) of the protective body 200 receives impact force to break, other parts (other protective pieces 201) of the protective body 200 can play a supporting role on the broken parts, and the broken parts are prevented from shifting, so that the comprehensive protection capability of the packaging assembly is improved, and the protective body has good practical value.

The material of the protective body 200 in the embodiment of the present application may be a commercially available foam, wherein two sides of each protective piece 201 may be embedded with the sides of two adjacent protective pieces 201, and the protective pieces 201 may be utilized to the greatest extent due to the embedding of the sides of the protective pieces 201, so as to form a protective layer matching with at least part of the outer surface of the product 500 to be protected, thereby saving cost.

Of course, in other embodiments, the adjacent protection pieces 201 may not be in an edge-to-edge engagement manner, that is, the side edge of one protection piece 201 may be engaged with the middle of another protection piece 201, and a protection layer that is wrapped around at least part of the outer surface of the product 500 to be protected may be configured. In this solution, the unnecessary unfavorable protecting member 201 is present, which may result in cost waste, but this solution may prolong the distance between the external collision object and the product 500 to be protected, which is more favorable for protecting the product to be protected.

In the embodiment of the present application, according to the appearance characteristics of the product to be protected 500, the protecting body 200 may be wrapped on the outer surface of the portion of the product to be protected 500, or may be wrapped on all the outer surfaces of the product to be protected 500, and may be set according to the specific shape of the product to be protected. For example, part of the outer surface (such as the back, the top or the bottom) of the product to be protected does not need to be specially protected, the protecting body 200 can not be coated on the outer surface which does not need to be specially protected, and the cost can be saved on the premise of achieving protection; if the outer surface of the product 500 to be protected needs to be protected, the protecting body 200 needs to be covered on the outer surfaces which do not need to be protected in particular, so as to protect the product 500 to be protected effectively.

The product to be protected according to the embodiment of the present application may be provided with a peripheral surface, and accordingly, the plurality of protection pieces 201 may enclose a protection cavity that is matched with the peripheral surface and is used for accommodating the peripheral surface, that is, the protection body 200 may only cover the peripheral surface of the product to be protected, so as to form a protection layer that only protects the peripheral surface of the product to be protected.

Of course, the product 500 to be protected may also be provided with a top portion connected to the top end of the peripheral side surface and a bottom portion connected to the bottom end of the peripheral side surface, and accordingly, the plurality of protecting members 201 may enclose a protecting cavity matched with the outer surface of the product to be protected, that is, the protecting body 200 may only cover all the outer surfaces of the product 500 to be protected, so as to form a protecting layer for protecting all the outer surfaces of the product 500 to be protected.

The embedding between the protection pieces 201 in the embodiment of the present application means that adjacent protection pieces 201 can be spliced into a detachable whole by means of self-plugging, mortise-tenon connection, and the like. When the spliced protective body 200 forms an integral structure, the outer surface of the part of the product 500 to be protected is coated; when the unitary structure is disassembled into the respective guards 201, the product 500 to be safeguarded can be conveniently and rapidly taken out.

In the embodiment of the application, two sides of the protecting piece 201 are in mortise and tenon connection with the side edges of the adjacent protecting pieces 201, so that the protecting body 200 is convenient to assemble and disassemble, and the product 500 to be protected has good loading and unloading efficiency.

In transporting the product 500 to be protected, each of the protection pieces 201 of the protection body 200 may be assembled on the outer circumferential surface to be protected first, and then each of the protection pieces 201 may be connected as a unit. In addition, the inner side surface of each protecting member 201 in the embodiment of the present application may be matched with the shape of the covered part of the product 500 to be protected, so that the product 500 to be protected may be effectively protected, while the outer side surface of each protecting member 201 preferably forms a relatively smooth surface, and an operation portion for holding may be provided on the outer side surface of the protecting member 201, and the operation portion may be in a hole shape or a groove shape, which is not limited herein.

Taking the to-be-protected product 500 as an oven as an example, the structure of the protecting body 200 will be further described, however, the to-be-protected product 500 may be an electrical device such as a refrigerator or a washing machine, or an industrial product such as porcelain, which is not limited herein.

The oven is generally hexahedral, i.e. it comprises four circumferential sides connected in sequence in the circumferential direction, and a top part connecting the top ends of the circumferential sides and a bottom part connecting the bottom ends of the circumferential sides. Fig. 2 is a schematic structural diagram of a protective body according to an embodiment of the present application, and referring to fig. 2, based on the above-mentioned oven, a protective body 200 according to an embodiment of the present application includes two first protective pieces 2011 and two second protective pieces 2012, wherein the two first protective pieces 2011 are oppositely coated on two sides extending in a first direction of a product 500 to be protected, the two second protective pieces 2012 are oppositely coated on two sides extending in a second direction of the product 500 to be protected, and the first direction and the second direction are different. Namely, each of the protecting pieces 201 of the protecting body 200 according to the embodiment of the present application is sequentially connected around the peripheral side surface of the product 500 to be protected to form a vertically penetrating box structure, namely, the protecting pieces 201 are provided only for four side surfaces of the oven.

Since four sides of the peripheral side of the oven are generally parallel to each other, the first direction and the second direction of the embodiment of the present application are in a perpendicular relationship, i.e., the first direction may be the X-axis and the second direction may be the Y-axis when the oven is placed on a horizontal plane. The two first guards 2011 and the two second guards 2012 are disposed opposite to each other to cover the peripheral side of the oven.

Of course, in other embodiments, if four sides of the peripheral side of the product 500 to be protected are approximately relatively parallel, the first direction and the second direction may be in an approximately vertical relationship, that is, an approximately vertical angle may be formed between the first direction and the second direction, and the angle may be 85 ° -95 °, and may be specifically set according to the shape of the peripheral side of the product 500 to be protected, which is not limited herein.

In order to prevent the top and bottom of the oven from collision and impact, the top of the box structure of the embodiment of the present application 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, in order to cover the outer surface of the toaster, each of the guard members 201 may be provided with a groove matching with the outer surface of the toaster such that the top of each guard member 201 covers the rim of the top of a portion of the toaster, or/and the bottom of each guard member 201 covers the rim of the bottom of a portion of the toaster such that the top of the case structure protrudes from the top of the toaster, or/and the bottom of the case structure may protrude from the bottom of the toaster such that the outer surface of the top of the toaster or/and the middle of the bottom of the toaster is not covered by the guard members 201, but may have a certain distance between the top of the toaster, the bottom of the toaster, and a collision object that may be generated by the guard members 201 through the support of the guard members on the sides of the toaster such that the collision object from the outside collides with the top and the bottom of the toaster is reduced to improve the reliability of the transportation protection of the toaster.

Since the shield body 200 only shields the side of the toaster, only four shields 201 are required, this embodiment requires fewer shields 201 than the scheme in which the shields 201 are provided to both the side and top and bottom of the toaster, and accordingly, manufacturing costs can be reduced.

Fig. 3 is a schematic structural view of a first protection member according to an embodiment of the present application, fig. 4 is a schematic structural view of a second protection member provided with a first mortise and tenon column according to an embodiment of the present application, and fig. 5 is a schematic structural view of a second protection member provided with a second mortise and tenon column according to an embodiment of the present application. Referring to fig. 3, 4 and 5, in the embodiment of the present application, two first protection pieces 2011 may be disposed on the left side and the right side of the oven, that is, the first direction of the embodiment of the present application may be the front-rear direction, and two second protection pieces 2012 may be disposed on the front side and the rear side of the oven, that is, the second direction of the embodiment of the present application may be the left-right direction, and the second direction is perpendicular to the first direction.

Referring to fig. 3, 4 and 5, one side of each first guard 2011 is provided with more than one first mortise and tenon interface 202, and the other side of each second guard 2012 is provided with more than one second mortise and tenon interface 203; correspondingly, in the two second guard pieces 2012, the first mortise and tenon posts 204 are arranged on two sides of one second guard piece 2012, the first mortise and tenon posts 204 on two sides are respectively in corresponding mortise and tenon connection with the first mortise and tenon interfaces 202 of the two first guard pieces 2011, the second mortise and tenon posts 205 are respectively arranged on two sides of the other second guard piece 2012, and the second mortise and tenon posts 205 on two sides are respectively in corresponding mortise and tenon connection with the second mortise and tenon interfaces 203 of the two first guard pieces 2011.

In the embodiment of the present application, the side surface of the first protection member 2011 may be provided with an inward concave portion, the concave portion may be the mortise and tenon joint, and the side surface of the second protection member 2012 may be provided with an outward extending protrusion, the protrusion may be the mortise and tenon column, and the corresponding protrusion and concave portion are engaged with each other, so that mortise and tenon connection between the mortise and tenon column and the corresponding mortise and tenon joint may be achieved.

In implementation, the two first protection pieces 2011 are firstly installed on the left side and the right side of the oven to be tightly attached to the oven, and as the two first protection pieces 2011 and the two first protection pieces 2011 are in mortise and tenon matching relation, the two second protection pieces 2012 can be directly pushed to the oven after being aligned with mortise and tenon interfaces of the first protection pieces 2011. When the second guard 2012 merges with the mortise and tenon interface of the first guard 2011, the two second guards 2012 are tightly attached to the oven, which is convenient and fast.

Further, in the embodiment of the present application, the two first mortise and tenon interfaces 202 and the two second mortise and tenon interfaces 203 are symmetrically arranged to ensure that the stress is symmetrical, and the first mortise and tenon interfaces 202 and the second mortise and tenon interfaces 203 are not at the same height in the vertical direction. This is because, since there is a possibility that the outer shape of the circumferential surface of the product 500 to be protected may be irregular, accordingly, the thicknesses of the parts of the protection member 201 where the first mortise and tenon joint 202 and the second mortise and tenon joint 203 are located are different, and the first mortise and tenon joint 202 and the second mortise and tenon joint 203 are disposed at different heights of the protection member 201, it is ensured that the first mortise and tenon joint 202 and the second mortise and tenon joint 203 are located at positions where the thicknesses are different. That is, the mortise and tenon interface in the embodiment of the application is preferably arranged on the thicker part of the guard 201, and the mortise and tenon interface on the thicker part of the guard 201 is strong, which is more beneficial to the integrity of the guard 200; in addition, mortise and tenon interfaces at different heights can also be beneficial to the integrity of the protection body 200, and the protection effect of the product 500 to be protected is further improved.

For the packaging assembly for an oven provided by the embodiment of the present application, the first mortise and tenon interface 202 of the embodiment of the present application may be disposed in the middle of the side of the first guard 2011, and the second mortise and tenon interface 203 may be disposed in the upper part of the side of the first guard 2011, because: because the middle size of oven etc. is thicker than the upper portion size, correspondingly, the middle thickness of first protector 2011 is less than the upper portion thickness of first protector 2011, is located the second mortise and tenon interface 203 of the upper portion of first protector 2011, and is strong with the mortise and tenon of second mortise and tenon post, more is favorable to the wholeness of protection body 200 to further improve the protection effect of treating protection product 500.

According to the packaging assembly provided by the embodiment of the application, the plurality of protection pieces 201 are connected into the integral protection body 200 through the lap mortise and tenon connection, and when any foam piece is impacted, the impact force can be dispersed to other protection pieces 201 through the connection and contact parts in the transportation process, so that the impact force to an oven is reduced, if any protection piece 201 is broken due to the impact force, the other protection pieces 201 also have supporting effect on the broken protection piece 201, and the broken protection piece 201 is prevented from shifting. Therefore, compared with the existing protective structure with the same protective capability, the packaging assembly with the lap mortise and tenon connection has the advantages that the thickness can be reduced by about 50% while the convenience in installation is ensured, the generation cost can be greatly reduced, the cabinet loading quantity can be increased, the sea transport cost is reduced, and the economic value is very good.

It should be noted that, in the embodiment of the present application, the first mortise and tenon joint 202 and the second mortise and tenon joint 203 may be provided with more, for example, three, four, etc., and correspondingly, the first mortise and tenon column-204 and the second mortise and tenon column-205 may be provided with more, for example, three, four, etc., which are not limited herein.

Referring to fig. 6, the saw-tooth-shaped friction portion 206 may be formed by sequentially connecting a plurality of triangles, and the triangle may be an isosceles triangle having a vertex angle of 120 °. Referring to fig. 7, for the wavy friction portion 206, it may be formed by sequentially connecting a plurality of protrusions, and the protrusions may be cubic spline curves based on two bottom corner points, two waist middle points and vertex points of an isosceles triangle with a vertex angle of 120 °.

The mortise and tenon interface with the friction part 206 is used, so that the acting area of the mortise and tenon interface is increased, the bearing capacity is increased, meanwhile, the mortise and tenon interface release mode is unique, the front and rear protection piece 201 can be released firstly, the fastening degree of the package is enhanced, the package integrity is further improved, and the protection effect is improved.

Of course, the friction portions 206 of the inner side walls of the first mortise and tenon joint 202 and the second mortise and tenon joint 203 may have other shapes, and the friction portions 206 may not be provided, that is, the inner side walls of the first mortise and tenon joint 202 and the second mortise and tenon joint 203 are planar, which is not limited herein.

It should be noted that, in the embodiment of the present application, it is preferable to only set the energy absorbing portion 208 at the corner of the bottom of the protection body 200, and the energy absorbing portion 208 set at the corner of the top of the protection body 200 is an alternative, so that a reasonable setting selection can be performed according to actual requirements; in addition, the energy absorbing portion may be provided at one or several corners of the shielding body 200, or the energy absorbing portion 208 may be provided at all corners of the shielding body 200. As for the specific number and arrangement area of the energy absorbing portions 208, a reasonable arrangement selection may be made according to actual requirements, which is not limited herein.

For example: protection of the side of the product 500 to be protected facing the operator (i.e., the front side of the product to be protected) is generally important, and thus, the energy absorbing portion 208 may be disposed only at the bottom or/and the corner of the protective body 200 covering the side of the product 500 to be protected facing the operator (as shown in fig. 9); also for example: the peripheral side of the product to be protected is usually provided with a light-transmitting portion, which may be a glass window for observation, or an operation panel, etc., in which case, the side of the protecting body 200 covered with the light-transmitting portion is provided with an energy-absorbing portion 208, such as: the light transmitting portion is disposed on a side of the product to be protected, and the energy absorbing portion 208 may be disposed only at a corner of the top or/and bottom of the side of the protective body 200 covering the light transmitting portion.

Since the two second protection pieces 2012 are sandwiched between the two first protection pieces 2011, the first protection pieces 2011 located on the outer side are more likely to cause collision impact, the embodiments of the present application preferably provide the energy absorbing portion 208 and the energy absorbing portion 208 at the bottom or/and top corners of the first protection pieces 2011 to improve the anti-collision impact capability of the protection body 200.

In general, each energy absorbing portion 208 may be made of a material having a density higher than that of the protective member 201, and the overall size of each energy absorbing portion may affect the protective capability of the energy absorbing portion, if the overall size of the energy absorbing portion is too small, the energy absorbing effect may be problematic, and if the overall size of the corner protector 300 is too large, the supporting protective effect on the protective body 200 may be weakened, so that the selection of the material and the size of the corner protector 300 needs to be studied.

Referring to fig. 8, in the protective body 200 according to the embodiment of the present application, a corner defect 209 may be formed at a portion where the energy absorbing portion 208 is disposed, and the corner protector 300 is accommodated in the corresponding corner defect 209, and the corner protector 300 is configured as the energy absorbing portion 208.

As a preferred embodiment of the present application, the corner protector 300 may be selectively and separately disposed in the corresponding unfilled corner 209, that is, when the protective body 200 is assembled, the bottom corner protector 300 is assembled in place, and the product 500 to be protected with the protective body 200 is placed in place. If the top corner protector 300 is present, the top corner protector 300 is assembled to the protective body 200.

Of course, the corner protector 300 in the embodiment of the present application may be integrally formed, adhered or heat-fused, and disposed in the corresponding unfilled corner 209, so as to have the above-mentioned anti-collision and impact capabilities.

In the related art, the corner protector is made of hard materials, and when an external collision object impacts the corner protector, the corner protector made of hard materials is likely to crush foam of the packaging assembly, so that the product 500 to be protected is damaged.

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

The D3O material is a shear thickening fluid formed by mixing an oily liquid lubricant and a polymer suspended therein. When a force is slowly applied to the shear thickening fluid, the polymer chains have time to move and rearrange, so the viscosity is not affected. However, if a force is applied rapidly, the polymer chains do not have time to rearrange and become entangled, and the viscosity increases greatly. Namely, when the corner protector 300 receives impact, the corner protector 300 made of the D3O material can absorb impact force, and compared with the hard corner protector 300, the situation that the corner protector 300 crushes the inner protective body 200 can be improved, and a better energy absorption effect is achieved.

In the case where the corner protector 300 is made of D3O material, the overall size of the corner protector 300 is required to be confirmed, and the damping effect is problematic because the overall size of the corner protector 300 cannot be too small, and if the overall size of the corner protector 300 cannot be too large, the structure supporting the corner protector 300 is weakened, and thus the size of the corner protector 300 is selected to be 70x30x30mm.

Also, the corner protector 300 comprising the honeycomb material with negative poisson's ratio can collapse to absorb local instantaneous large energy, and when the corner protector 300 is impacted by collision, the corner protector 300 can shrink, compared with the hard corner protector 300, the situation that the corner protector 300 crushes the inner protective body 200 can be improved, and the energy absorption effect is better. The corner protector 300 comprising the negative poisson's ratio honeycomb material can be composed of three parts, upper and lower kraft paper layers and a middle negative poisson's ratio metamaterial.

The local damping band gap of the corner protector 300 of the local resonance metamaterial is realized through local resonance between the microstructure of the corner protector and the frequency of external wave, and the external wave energy can be absorbed and converted into the kinetic energy of an internal resonator, so that wave propagation inhibition is realized. The impact frequency of the oven angle drop is about hundred hertz, so that the local resonance frequency of the metamaterial is also about hundred hertz. This requires a rational design of the structure and material properties of the metamaterial.

When the corner protector 300 receives the collision impact, the vibration exciter 305 can absorb the generated collision impact force, has the characteristic of buffering and absorbing energy, and compared with the hard corner protector 300, the situation that the corner protector 300 crushes the inner protection body 200 can be avoided to a certain extent, and has a better energy absorbing effect.

Fig. 13 is a schematic structural view of a package assembly with a support. Referring to fig. 13, the package assembly according to the embodiment of the present application may further include a supporting body 400, wherein a receiving cavity for receiving the shielding body 200 is provided in the supporting body 400, and when the shielding body 200 is received in the receiving cavity, the shielding body 200 is in contact with an inner wall of the supporting body 400.

In the package assembly according to the embodiment of the application, since the package assembly includes the support body 400 for accommodating the protective body 200, in the transportation process, the support body 400 disposed outside the protective body 200 can protect the protective body 200 on one hand, and can reduce the impact force applied to the protective body 200, so as to reduce the breakage phenomenon of the protective body 200, and if one of the protective pieces 201 of the protective body 200 breaks, the support body 400 disposed outside the protective body 200 can also support the breaking portion of the protective body 200, thereby preventing the breaking portion from shifting, so as to furthest exert the comprehensive protection capability of the package assembly, and the package assembly has good practical value.

In this embodiment of the present application, the support body 400 located outside may include a corrugated or cardboard box, which is wrapped around the outer surface of the protection body 200 to perform a primary protection function, and may provide an assembly space for the integral protection member 201 to support the integral protection body 200, so as to prevent the protection member 201 from being damaged due to collision and splitting, thereby performing a good protection function on the product 500 to be protected.

When the product 500 to be protected is transported, the protecting body 200 may be assembled on the outer circumferential surface of the product 500 to be protected, and then the supporting body 400 may be sleeved on the protecting body 200. In addition, in the embodiment of the present application, the inner side surface of each protection piece 201 is matched with the shape of the covered part of the product 500 to be protected, and the outer side surface of each protection piece 201 is in plane contact with the inner side part of the accommodating cavity, so that no gap can be formed between the support body 400 and the protection body 200 and between the protection body 200 and the product 500 to be protected after the product 500 to be protected is assembled in the packaging assembly, thereby playing a role in firmly protecting the product 500 to be protected, and further improving the protection effect of the product 500 to be protected.

Referring to fig. 13, the accommodating cavity in the embodiment of the present application may be provided with an opening 401 for accommodating the protection body 200, that is, after the product 500 to be protected is assembled into the support body 400, the support body 400 assembled with the product to be protected may enter the accommodating cavity of the support body 400 from the opening 401, and then the opening 401 of the support body 400 may be closed.

In some embodiments, the opening 401 has an opening area not larger than the circumferential cross-sectional area of the shielding body 200, so that when the shielding body 200 is received in the receiving cavity, the shielding body 200 can expand the receiving cavity, and the shielding body 200 is tightly attached to the inner wall of the supporting body 400. Namely, when the protection body 200 is accommodated in the accommodating cavity, the negative gap between the protection body 200 and the support body 400 can further improve the integrity of the protection body 200, so as to prevent the phenomenon that the product to be protected cannot be effectively protected due to the loosening of the protection body 200 in the transportation process as much as possible.

In the case of the support body 400, and under the working condition that the corner protector 300 is separately disposed in the corresponding unfilled corner 209, when the protection body 200 is assembled in the support body 400, the bottom corner protector 300 is assembled in the support body 400, and the product 500 to be protected with the protection body 200 is placed in the support body 400. If a top corner protector exists, the top corner protector 300 is assembled on the protective body 200.

Since the interior of the protective body 200 according to the embodiment of the present application is shaped to match the external shape of the product to be protected, the protective body 200 is irregularly shaped, and has a thickness of not more than 10mm, i.e., 10mm or 9 mm.

The packaging component in the related art has the defects of large foam thickness and large corresponding outer packaging size. Taking an oven as an example, the oven in the related art has a cabinet size of 216=3x4x18. By adopting the packaging assembly provided by the embodiment of the application, the corresponding external package size is small, and the cabinet loading amount is 304 = 4x4x19. If the sea transport cost of a single container is $ 12000, the sea transport cost of a single oven is reduced by 100 yuan. The oven has 100 tens of thousands of pins per year, can reduce the cost by 1 hundred million yuan per year, and has the cost of about 27 yuan because of the reduced thickness of foam, 9.2 yuan lower than the original package, 900 ten thousand yuan lower in year, and has very obvious economic benefit.

In summary, the packaging assembly provided by the application can exert the comprehensive protection capability of the packaging assembly to the greatest extent, reduce the generation cost and the transportation cost, and has good practical value.
