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

fig. 1 is a schematic view of a packaging assembly in the development process of the applicant. Referring to fig. 1, the packaging assembly includes two foams 100 'oppositely disposed on opposite sides of a product 500 to be protected, the two foams 100' are oppositely disposed and separated, no integration is formed, no stability is provided, the two separated foams 100 'provide a limited cushioning protection area for the product, no overall protection can be formed, and the fixation between the two separated foams 100' and the product depends on an externally wrapped corrugated or cardboard box, which has high cost and large improvement space.

Based on the problems of the packaging assembly, the embodiment of the application provides the packaging assembly, and aims to solve the technical problems of instability in protection, incapability of comprehensive protection and high cost of the packaging assembly during transportation of a product 500 to be protected to at least a certain extent.

Fig. 2 is a schematic view of a package assembly according to an embodiment of the present application. With reference to fig. 2, the packaging assembly of the present application is used for transportation protection of products to be protected, and includes a protection body 200, and the protection body 200 can be coated on at least part of the outer surface of the products to be protected to form a protection layer for protecting the products during transportation.

The protection body 200 of the embodiment of the present application includes more than three protection parts 201, wherein one protection part 201 is embedded with two adjacent protection parts 201, and supports two adjacent protection parts 201, so that the protection body 200 can form an integral protection structure, and in the transportation process, if a certain part (a certain protection part 201) of the protection body 200 receives an impact force, the impact force can be dispersed to other parts through other parts (other protection parts 201) of the protection body 200, so as to reduce the impact force of the product 500 to be protected, and if the certain part (a certain protection part 201) of the protection body 200 is broken by the impact force, the other parts (other protection parts 201) of the protection body 200 can support the broken part, so as to prevent the broken part from being displaced, so as to improve the comprehensive protection capability of the packaging component, and have a good practical value.

The protection body 200 of the embodiment of the present application may be made of a commercially available foam, wherein both sides of each protection member 201 may be engaged with the side edges of two adjacent protection members 201, and since the side edges of the protection members 201 are engaged with each other, the protection members 201 may be utilized to the maximum extent to form a protection layer matching with at least a part of the outer surface of the product 500 to be protected, so as to save cost.

Of course, in other embodiments, adjacent protection components 201 may not be engaged in a side-to-side manner, that is, the side of one protection component 201 may be engaged in the middle of another protection component 201, and a protection layer may be configured to be coated on at least a part of the outer surface of the product 500 to be protected. This solution causes a waste of cost because there is a surplus of the protection member 201 which is not advantageous, but it extends the distance between the external collision object and the product 500 to be protected, and is more advantageous for protecting the product to be protected.

In the embodiment of the present application, according to the shape characteristics of the product 500 to be protected, the protection body 200 may be wrapped on the outer surface of the portion of the product 500 to be protected, or may be wrapped on all the outer surfaces of the product 500 to be protected, and may be set according to the specific shape of the product to be protected. For example, part of the outer surface (e.g., back, top, bottom, etc.) of the product to be protected does not need special protection, and the protective body 200 may not be coated on the outer surface that does not need special protection, so that 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 completely protected, the protecting body 200 needs to be completely coated on the outer surface which does not need to be specially protected, so as to effectively protect the product 500 to be protected.

The product of treating protection of this application embodiment can be provided with all sides, and correspondingly, a plurality of guards 201 can be enclosed and all sides phase-match and be used for holding the protection chamber of all sides, and protection body 200 can only wrap on the all sides of the product of treating protection promptly to form the inoxidizing coating that only treats all sides of the product of protecting and protect.

Of course, the product 500 to be protected may 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, and accordingly, the plurality of protection members 201 may enclose a protection cavity matching the outer surface of the product 500 to be protected, i.e. the protection body 200 may only be coated on the whole outer surface of the product 500 to be protected, so as to form a protection layer for protecting the whole outer surface of the product 500 to be protected.

The interlocking between the protection parts 201 in the embodiment of the present application means that the adjacent protection parts 201 can be spliced into a detachable whole by means of self-plugging, mortise and tenon connection, etc. When the spliced protection body 200 forms an integral structure, the protection body is used for coating the outer surface of the part of the product 500 to be protected; when the integrated structure is disassembled into the individual protection members 201, the product 500 to be protected can be conveniently and quickly taken out.

In the embodiment of the present application, two sides of the protection component 201 are mortise and tenon connected with the side edges of the adjacent protection component 201, so as to facilitate the assembly and disassembly of the protection body 200, and make the product 500 to be protected have better loading and unloading efficiency.

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

Now, the structure of the protection body 200 will be further described by taking the product 500 to be protected as an oven as an example, but the product 500 to be protected may also be electric equipment such as a refrigerator or a washing machine, and may also be industrial products such as porcelain, and the invention is not limited herein.

The oven is generally hexahedral, i.e. it comprises four circumferential sides connected in succession along the circumferential direction, as well as a top portion connecting the top ends of the circumferential sides and a bottom portion connecting the bottom ends of the circumferential sides. Fig. 2 is a schematic structural diagram of a protection body according to an embodiment of the present application, and with reference to fig. 2, based on the above-mentioned oven, the protection body 200 according to the embodiment of the present application includes two first protection parts 2011 and two second protection parts 2012, where the two first protection parts 2011 are relatively covered on two sides of the product 500 to be protected extending in the first direction, the two second protection parts 2012 are relatively covered on two sides of the product 500 to be protected extending in the second direction, and the first direction and the second direction are different. Namely, the protection parts 201 of the protection body 200 of the embodiment of the present application are sequentially connected to form a vertically through box structure around the peripheral side of the product 500 to be protected, that is, the protection parts 201 are only arranged on the four sides of the oven.

Since the four sides of the peripheral side of the oven are generally parallel two by two, the first direction and the second direction of the embodiment of the present application are in a perpendicular relationship, that is, when the oven is placed on a horizontal plane, the first direction may be an X axis, and the second direction may be a Y axis. The two first guards 2011 and the two second guards 2012 are disposed opposite to each other to cover and protect 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 parallel, the first direction and the second direction may be approximately perpendicular, that is, the first direction and the second direction have an approximately perpendicular included angle therebetween, which may be 85 ° to 95 °, and may be specifically configured according to the shape of the peripheral side of the product 500 to be protected, which is not limited herein.

To protect the top and bottom of the oven from impact impacts, the top of the box structure of embodiments 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 oven, each protection member 201 may be provided with a groove matching with the outer surface of the oven, so that the top of each protection member 201 covers a portion of the edge of the top of the oven, or/and the bottom of each protection member 201 covers a portion 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 may protrude from the bottom of the oven, so that the outer surface of the top of the oven or/and the middle of the bottom is not covered by the protection member 201, but may have a certain distance between the top of the oven, the bottom of the oven and a possible collision object through the support of the protection member 201 at the side of the oven, so as to reduce the risk of collision impact objects hitting the top and the bottom of the oven, and improve the reliability of the transportation protection of the oven.

Since the protection body 200 protects only the side of the oven, only four protection members 201 are required, which requires fewer protection members 201 than a solution in which the protection members 201 are provided to both the side and the top and bottom of the oven, and accordingly, the manufacturing cost can be reduced.

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

With reference to fig. 3, 4 and 5, one side of each first protection part 2011 is provided with more than one first mortise and tenon interface 202, and the other side of each second protection part 2012 is provided with more than one second mortise and tenon interface 203; correspondingly, in two second protection parts 2012, two sides of one second protection part 2012 are provided with first mortise and tenon column 204, the first mortise and tenon column 204 on two sides respectively corresponds mortise and tenon connection with first mortise and tenon interface 202 of two first protection parts 2011, two sides of another second protection part 2012 are respectively provided with second mortise and tenon column 205, and second mortise and tenon column 205 on two sides respectively corresponds mortise and tenon connection with second mortise and tenon interface 203 of two first protection parts 2011.

In implementation, the two first protection parts 2011 are first installed at the left and right sides of the oven to be tightly attached to the oven, and since the two first protection parts 2011 and the two first protection parts 2011 are in a mortise and tenon matching relationship, the two second protection parts 2012 can be directly pushed to the oven after the second protection parts 2012 are aligned with the mortise and tenon interfaces of the first protection parts 2011. When the second protection part 2012 is combined with the mortise and tenon joint of the first protection part 2011, the two second protection parts 2012 are just tightly attached to 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 of the embodiment of the present application 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 located at the same height in the vertical direction. This is because, since there may be irregular shapes on the peripheral surface of the product 500 to be protected, accordingly, the thicknesses of the portions of the protection element 201 where the first mortise and tenon interface 202 and the second mortise and tenon interface 203 are located are different, and the first mortise and tenon interface 202 and the second mortise and tenon interface 203 are disposed at different heights of the protection element 201, so that the first mortise and tenon interface 202 and the second mortise and tenon interface 203 can be ensured to be located at positions with different thicknesses. That is, the mortise and tenon interface in the embodiment of the present application is preferably disposed on the thicker portion of the protection element 201, and the mortise and tenon of the mortise and tenon interface on the thicker portion of the protection element 201 is robust, which is more favorable for the integrity of the protection body 200; in addition, mortise and tenon interfaces at different heights can also be beneficial to the integrity of the protection body 200, and further improve the protection effect of the product 500 to be protected.

It should be noted that, in the embodiment of the present application, it is preferable to provide the energy absorbing portion 208 only at the bottom corner of the protection body 200, and the energy absorbing portion 208 provided at the top corner of the protection body 200 is an alternative, and the setting selection can be rationalized according to the actual requirement; additionally, energy absorbing portions may be provided at one or more corners of the protective body 200, or energy absorbing portions 208 may be provided at all corners of the protective body 200. As for the specific arrangement number and arrangement area of the energy absorbing portion 208, the arrangement selection can be rationalized according to the actual requirement, and is not limited herein.

For example: protection of the front side (i.e., the side facing the consumer) of the product 500 to be protected is generally of particular importance, and therefore, embodiments of the present application may be provided with energy absorbing portions 208 only at the bottom or/and corners of the front side of the protective body 200 (as shown in fig. 9); another example is: 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 covering the light-transmitting portion is provided with an energy-absorbing portion 208, such as: the light-transmitting part is arranged on the side surface of a product to be protected, and the energy-absorbing part 208 can be arranged only on the top or/and the bottom corner of the side surface of the protective body 200 covering the light-transmitting part.

Since the two second guards 2012 are sandwiched between the two first guards 2011, the first guard 2011 located at the outer side is more likely to cause collision impact, and therefore, in the embodiment of the present application, the energy absorbing portion 208 and the energy absorbing portion 208 are preferably disposed at the bottom or/and the top corner of the first guard 2011, so as to improve the collision impact prevention capability of the protection body 200.

Generally, each energy absorbing portion 208 may be made of a material having a density higher than that of the protection member 201, the overall size of each energy absorbing portion may affect the protection 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 and protecting effect on the protection 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 guard 200 according to the embodiment of the present invention, a notch 209 may be formed at a portion where the energy absorbing portion 208 is provided, the corner protector 300 is accommodated in the corresponding notch 209, and the corner protector 300 is disposed as the energy absorbing portion 208.

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

Of course, the corner protectors 300 in the embodiment of the present application may also be integrally formed, adhered or heat-melted in the corresponding unfilled corners 209, and have the above-mentioned anti-collision and impact-proof capability.

Among the correlation technique, the material of angle bead is mostly hard material, and when external bump striking angle bead, hard material's angle bead is probably with the foam crushing of package assembly to treat that protection product 500 causes the technical problem of damage, this application embodiment provides an angle bead with buffering energy-absorbing.

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

The D3O material is a shear thickening fluid that is a mixture of 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, and thus the viscosity is not affected. However, if a force is applied rapidly, the polymer chains are not time-rearranged and become entangled, and the viscosity is greatly increased. That is, when the corner protector 300 is subjected to a collision impact, the corner protector 300 made of D3O material can absorb the collision impact, and compared to the hard corner protector 300, the situation that the inner protector 200 is crushed by the corner protector 300 can be improved, and a better energy absorption effect can be obtained.

In the case where the corner protector 300 is made of D3O material, it is necessary to confirm the overall size of the corner protector 300, and since the overall size of the corner protector 300 cannot be made too small, there is a problem in the damping effect, and if the overall size of the corner protector 300 cannot be made too large, the structure supporting the corner protector 300 is weakened, and therefore the size of the corner protector 300 is selected to be 70x30x30mm.

Similarly, the angle bead 300 made of the honeycomb material with the negative poisson ratio can collapse to absorb local instantaneous large energy, when collision impact is applied, the angle bead 300 can contract, and compared with the hard angle bead 300, the condition that the angle bead 300 crushes the internal protection 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, namely upper kraft paper, lower kraft paper and middle negative poisson's ratio metamaterial.

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

When the corner protector 300 is impacted by collision, the vibration exciter 305 can absorb the generated collision impact force, so that the energy absorption characteristic is achieved, and compared with the hard corner protector 300, the situation that the inner protective body 200 is crushed by the corner protector 300 can be avoided to a certain extent, and the energy absorption effect is better.
