Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and more specifically, to a cushioning packaging base for household appliances. Background Art

[0002] The cushioning packaging base of household appliances is a packaging component used to support and fix white household appliances and protect them during transportation and storage. White household appliances are a specific category name for household appliances. White household appliances refer to electrical appliances that can replace people's housework, mainly including washing machines, some kitchen appliances, and those that improve the living environment and improve the material living standards (such as air conditioners, refrigerators, etc.).

[0003] With the booming home appliance industry, the transportation and storage safety of home appliances is of vital importance. As a key protective component, the cushioning packaging base is facing many challenges and changes. The existing base is generally made of foam plastics, paper materials (corrugated cardboard), etc. The existing foam solution uses a mold to form a protective effect in one step, but the mold cost of the foam product is high and the mold making and repairing cycle is long. In addition, foam plastics are difficult to degrade and recycle, and foam packaging is highly polluting to the environment, and toxic and harmful substances will volatilize during the production process; some European and Australian countries have promulgated relevant regulations to prohibit the use of white foam materials in the packaging of imported products. In order to respond to the international call for regulations to ban foam plastics, it is also necessary to avoid the use of home appliance cushioning packaging made of foam plastics as much as possible.

[0004] For home appliances that need to be exported and transported by sea, the cushioning packaging needs to meet the high temperature and high humidity environment of sea transportation, so as to fully protect the goods during the long and complex transportation. In a high temperature and high humidity environment, the base made of paper materials (corrugated cardboard) may affect the effect of the home appliance cushioning packaging and the structural strength of the cushioning parts due to the high temperature and high humidity environment. For this reason, it is also necessary to avoid using home appliance cushioning packaging made of paper materials (corrugated cardboard) as much as possible.

[0005] Under the industry trend of energy conservation and consumption reduction, it is necessary to comply with environmental protection policies and adapt to the high temperature and high humidity environment of sea transportation, minimize costs, and achieve the same cushioning effect as foam materials, while providing sufficient protection. Therefore, environmentally friendly and recyclable polypropylene materials can be used to manufacture hollow boards, and then the hollow boards can be made into home appliance cushioning packaging bases. Home appliance cushioning packaging bases made of hollow boards have lower costs and simpler production processes. Home appliance cushioning packaging bases made of polypropylene inherit the chemical corrosion resistance of polypropylene materials, can resist erosion by a variety of chemical substances, and can adapt to the high temperature and high humidity environment of sea transportation. Home appliance cushioning packaging bases made of polypropylene materials are made of hollow boards, which inherit the seismic cushioning properties of hollow boards to achieve the same cushioning effect as foam materials.

[0006] Among them, the hollow board is a board with a hollow structure inside. It is usually made of two or more layers of flat plates connected by a specific process, forming a uniformly distributed hollow layer in the middle. The hollow structure design greatly reduces the weight of the board while ensuring a certain strength of the board; it enhances the vibration resistance of the board, so that the home appliance cushioning packaging base made of the hollow board has the same cushioning effect as the foam material. Specifically, for the seismic resistance, because the polypropylene material has a certain flexibility and elasticity, the molecular chain of the hollow board can be deformed to a certain extent when it is vibrated or impacted, thereby absorbing and dispersing part of the energy and improving the seismic buffering performance. When vibrated, the hollow structure of the hollow board can play a role of buffering and isolation, reduce the propagation of vibration waves inside the board, and improve the seismic buffering performance. The hollow structure and wall thickness inside the hollow board can also be reasonably designed so that the vibration resistance of the board in all directions is relatively balanced, for example, the hollow structure is evenly distributed. When the vibration comes from different directions, the evenly distributed hollow structure can evenly disperse and absorb energy, avoiding local excessive force and causing damage to the board. Designing the appropriate wall thickness can ensure that the plate has sufficient strength and rigidity to resist the stress and deformation generated during vibration.

[0007] Therefore, the home appliance cushioning packaging base made of hollow board can effectively protect the product from damage by vibration and collision during transportation and storage.

[0008] In order to meet the requirements of environmental protection and high temperature and high humidity, without sacrificing the protective effect, a home appliance packaging base with lower cost and simpler production process is needed. A home appliance cushioning packaging base made of polypropylene hollow board is needed, which is convenient for packaging, transportation and disassembly. Summary of the invention

DETAILED DESCRIPTION

[0025] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0026] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0028] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0029] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0030] Embodiment 1 Reference Figure 1-Figure 7 The household appliance buffer packaging base provided in this embodiment includes a base 10 and a support assembly 40 detachably connected to the base 10; wherein a protective assembly 50 is fixed to the outer wall of the base 10 in a circumferential direction, and the protective assembly 50 includes a protective strip 51 for protecting the bottom edge of the base 10, a first protective fixing member 52 for protecting the side edge of the base 10 and connecting two adjacent protective strips 51, and a second protective fixing member 53 connecting two adjacent protective strips 51 and the first protective fixing member 52, so as to protect the bottom edge and side edge of the outer side of the base 10; the base 10 includes an outer frame 20 and an inner frame assembly 30 connected to the outer frame 20, and one or more support assemblies 40 are detachably connected to the inner frame assembly 30; specifically, a groove strip 31 is provided on the inner frame assembly 30, and the support assembly 40 includes a main support block 41 and a buffer support block 42 which are detachably connected, and the main support block 41 extends from the bottom of the groove strip 31 and is plugged into the buffer support block 42 located above the inner frame assembly 30. In order to improve the practicability of the household appliance cushioning package, a avoidance hole 11, a plug-in slot 12 and a avoidance slot 13 may be provided on the base 10; and a passive smart label is fixed on the base.

[0031] It is understandable that the home appliance cushioning packaging base is composed of a base 10 and a support assembly 40, which are detachably connected. This design is not only convenient for packaging and transportation, but also convenient for later disassembly and recycling. The base 10 includes an outer frame 20 and an inner frame assembly 30 connected to the outer frame 20. The outer frame 20 serves as the overall shape constraint framework of the base. When the base is subjected to a drop impact, it can provide sufficient bending strength and effectively reduce the inward conductive shock wave, thereby protecting the home appliance from direct damage by external impact force. The inner frame assembly 30 is mainly composed of a multi-layer slotted hollow plate, which can not only limit the range of motion of the internal support assembly 40, but also absorb the external impact force layer by layer when the base is subjected to a drop impact, preventing the impact force from directly acting on the home appliance body, thereby avoiding damage to the body.

[0032] The protective assembly 50 is composed of a protective strip 51, a first protective fixture 52 and a second protective fixture 53. The protective strip 51 focuses on protecting the bottom edge of the bottom bracket. The first protective fixture 52 is closely connected to the adjacent protective strips 51 to protect the side edge of the bottom bracket. The second protective fixture 53 further strengthens the connection stability between the adjacent protective strips 51 and the first protective fixture 52, and together builds an indestructible protection system to effectively resist various external collisions and impacts. By protecting the bottom edge and side edge of the outer side of the base 10, the bottom bracket is provided with all-round protection. When the bottom bracket collides or rubs with other objects during transportation, use or storage, the protective assembly 50 can first withstand the impact force, reduce the direct damage to the bottom bracket, and prevent scratches or wear on the surface of the bottom bracket, which affects the stability of the bottom bracket. It should be noted that the protective strip 51 can be fixed to the bottom edge of the bottom bracket in a variety of ways. Common fixing methods include pasting, snapping, screw fixing, etc. Pasting is suitable for some occasions where the fixing strength is not required. By applying glue or double-sided tape on the contact surface of the protective strip 51 and the base, the protective strip 51 can be firmly attached to the base. The buckle fixation uses the buckle structure designed on the protective strip 51 and the base to clip the protective strip 51 into the card slot of the base. This fixing method is easy to disassemble and can be reused. Screw fixation is suitable for situations where high fixing strength is required. Holes are punched on the protective strip 51 and the base, and then they are tightened and fixed with screws. Different fixing methods can be selected according to actual needs.

[0033] The base 10 is provided with a position-avoiding hole 11, a plug-in slot 12 and a position-avoiding slot 13 to meet different installation and use requirements. For example, for a drum washing machine, the position-avoiding hole 11 is used to place the four corners of the drum washing machine, the plug-in slot 12 is used to insert the column, and the position-avoiding slot 13 is used to place the water outlet pipe, three-phase plug, etc. of the drum washing machine. It should be noted that the position-avoiding hole 11 runs through the base 10, that is, through the outer frame 20 and the inner frame assembly 30; at the same time, a passive smart tag is fixed on the bottom bracket to facilitate the tracking and management of home appliances.

[0034] The protective component 50, the outer frame 20 and the inner frame component 30 relieve the impact force layer by layer, effectively absorbing the impact while ensuring the stability of the structure, and cooperating with the support component 40 to support the home appliances, thereby fully ensuring the safety of the home appliances during transportation and storage.

[0035] It should be noted that the above-mentioned embodiment is suitable for heavy household appliances, such as drum washing machines. The protective component 50, the outer frame 20 and the inner frame component 30 unload the impact force layer by layer, effectively absorbing the impact while ensuring the stability of the structure, and cooperating with the support component 40 to support the household appliances, thereby comprehensively ensuring the safety of the household appliances during transportation and storage, and preventing the packaging from receiving a large impact during transportation, causing the packaging to fall apart and affecting the protective effect. For light household appliances, such as pulsator washing machines, the impact received by the packaging during transportation is much lower than that of pulsator washing machines, and the packaging is not easy to fall apart. At this time, you can refer to Figure 3 The outer frame 20 is integrally formed by injection molding, and there is no need for a protective component 50 to connect and fix the components of the outer frame 20. The outer frame 20 can be formed into a box body with an opening upward to place the inner frame component 30, thereby reducing manufacturing and processing costs.

[0036] When using the home appliance buffer packaging base provided in this embodiment, insert the first groove 411 side plate of one or more main support blocks 41 along the groove strip 31 opened on the inner frame assembly 30 to achieve preliminary horizontal limit of the main support block 41, ensuring that its position is accurate and not prone to left and right deviation. The first groove 411 side plate of the main support block 41 extends from the bottom of the groove strip 31 opened on the inner frame assembly 30, further limiting and fixing, preventing the main support block 41 from falling downward in the vertical direction, and providing a stable bottom support foundation for the entire support assembly 40. Then, the buffer support block 42 is staggered and plugged with the corresponding main support block 41 to ensure that the two are tightly and firmly connected.

[0037] The protection strip 51 protects the bottom edge of the outer frame 20, the first protection fixture 52 closely connects the adjacent protection strips 51 and protects the side edge of the outer frame 20, and the second protection fixture 53 connects the protection strip 51 and the first protection fixture 52 to strengthen the connection stability between the adjacent protection strips 51 and the first protection fixture 52, and together builds an indestructible protection system to prevent the outer frame 20 from falling apart. The inner frame assembly 30 with the support assembly 40 installed is placed as a whole in the outer frame 20, and the nesting is achieved through the size design of the inner and outer frames 20. The passive smart tag is fixed on the bottom bracket to facilitate the tracking and management of home appliances, and the installation of the bottom bracket is completed.

[0038] It should be noted that the outer frame 20 can also be an integrally formed outer frame 20 produced by open mold injection molding. There is no need for the protective component 50 to connect and fix the components of the outer frame 20. The outer frame 20 can be formed into a box body with an opening upward to place the inner frame component 30, thereby reducing manufacturing and processing costs.

[0039] Embodiment 2 Based on the first embodiment, according to the characteristics and requirements of different components inside the home appliance, support components 40 with different structures and shapes are designed to provide accurate and stable support for key components of the home appliance, thereby ensuring the stability and safety of each component during transportation. Figure 1-Figure 13 The support assembly 40 includes a main support block 41 and a buffer support block 42 which are detachably connected. The main support block 41 and the buffer support block 42 are staggered and inserted to form the support assembly 40. The support assembly 40 also includes an elastic support member 43 which is detachably connected to the fixing hole 32 provided on the inner frame assembly 30.

[0040] The main support block 41 includes a plurality of first grooves 411 connected to each other, and first slots 412 are provided on the side panels of the first grooves 411 at intervals, and a first insertion strip 413 is formed between two adjacent first slots 412. The inner frame assembly 30 is provided with a groove strip 31, which is adapted to the side panels of the first grooves 411 and is used to insert the side panels of the first grooves 411. The buffer support block 42 includes a plurality of second grooves 421 connected to each other, and second slots 422 are provided on the side panels of the second grooves 421 at intervals, and a second insertion strip 423 is formed between two adjacent second slots 422; the support assembly 40 also includes a support plate 44, and a multi-directional limiting groove 414 is provided at the bottom of the main support block 41, which runs through one or more first grooves 411 in a transverse direction, and the multi-directional limiting plate 44 is plugged into the multi-directional limiting groove 414.

[0041] Specifically, the corresponding first insertion strips 413 are adapted to the horizontal distance between the side panels of the second grooves 421, the corresponding second insertion strips 423 are adapted to the horizontal distance between the side panels of the adjacent first grooves 411, the first slots 412 are adapted to the side panel width of the buffer support block 42, and the second slots 422 are adapted to the side panel width of the main support block 41; the height of the first insertion strip 413 is adapted to the height of the corresponding second slots 422, and the top surface inclination angle and shape of the first insertion strip 413 are adapted to the bottom plate inclination angle and shape of the corresponding second groove 421.

[0042] It is understandable that the detachably connected main support block 41 and the buffer support block 42 are interlaced to form a support assembly 40, thereby providing corresponding support for household appliances. The groove strip 31 on the inner frame assembly 30 is adapted to the first groove 411 side plate of the main support block 41, so that the main support block 41 can be inserted and positioned through the groove strip 31. Among them, the first groove 411 can be composed of one or more layers of hollow plates. During installation, the first groove 411 side plate of the main support block 41 is inserted along the groove strip 31 to achieve preliminary positioning of the main support block 41 in the horizontal direction, ensuring that its position is accurate and not prone to left and right deviation. The main support block 41 extends from the bottom of the groove strip 31 of the inner frame assembly 30, which can play a further role in limiting and fixing, preventing the main support block 41 from falling downward in the vertical direction, and providing a stable bottom support foundation for the entire support assembly 40. Matching slots and flanges may also be designed on the main support block 41 and the buffer support block 42 for simple positioning to prevent displacement during the plug-in process. This can also improve the tightness of the connection between the main support block 41 and the buffer support block 42 to prevent loosening.

[0043] The elastic support member 43 can be connected to the fixing hole 32 opened on the inner frame assembly 30 in a detachable manner. When the household appliance is impacted by external force, the elastic support member 43 can be elastically deformed, absorb and dissipate part of the impact force, further enhance the buffering performance of the entire support assembly 40, reduce the impact of the impact force on the household appliance, and can also rely on its elastic recovery force to maintain the close connection between the support assembly 40 and the base 10, ensuring that the household appliance is always in the correct placement position. The elastic support member 43 also plays the role of auxiliary support in the support assembly 40, and cooperates with the main support block 41 and the buffer support block 42 to improve the stability and reliability of the support. Its detachable connection method is convenient for operation when the elastic support member 43 is damaged or needs to be replaced, and does not affect the structural integrity of the entire support assembly 40. There are differences in size, weight and shape of household appliances of different models and specifications. The elastic characteristics of the elastic support member 43 enable it to be adaptively adjusted within a certain range to meet the packaging requirements of different household appliances.

[0044] Specifically, the main support block 41 is composed of a plurality of first grooves 411 connected to each other, and the buffer support block 42 is composed of a plurality of second grooves 421 connected to each other. The design of the first groove 411 and the second groove 421 increases the structural complexity of the main support block 41 and the buffer support block 42, so that the main support block 41 and the buffer support block 42 can absorb and disperse energy through the deformation of the first groove 411 and the second groove 421 when subjected to pressure, thereby playing a buffering role. Second slots 422 are spaced apart on the side panels of the second groove 421, and second insertion strips 423 are formed between two adjacent second slots 422. This structure cooperates with the first insertion strip 413 and the first slot 412 of the main support block 41 to achieve staggered insertion of the main support block 41 and the buffer support block 42, ensuring that the two are tightly and firmly connected. At the same time, the main support block 41 and the buffer support block 42 can evenly disperse the weight of the home appliance to avoid damage to the home appliance caused by excessive local pressure; when impacted by external force, the main support block 41 and the buffer support block 42 can disperse the impact force through the deformation of the hollow plate and the connection structure of the main support block 41 and the buffer support block 42, so that the impact force will not be concentrated at a certain point or a certain area, thereby better protecting the home appliance products, ensuring that the main support block 41 and the buffer support block 42 can effectively absorb and buffer these vibrations and impacts during transportation, reduce damage to the home appliance, protect the key components of the home appliance, and ensure the stability and safety of each component during transportation.

[0045] In order to quickly, accurately and firmly connect the main support block 41 and the buffer support block 42 to form the support assembly 40, and to firmly fix it on the inner frame assembly 30, the compatibility between the components must be ensured. The horizontal distance between the corresponding first insertion strip 413 and the side plate of the second groove 421 is matched, and the horizontal distance between the corresponding second insertion strip 423 and the side plate of the adjacent first groove 411 is also matched, to ensure that during the plug-in process, the components can be accurately docked in the horizontal direction to avoid looseness, misalignment, etc. The first slot 412 is matched with the side plate width of the buffer support block 42, and the second slot 422 is matched with the side plate width of the main support block 41. This helps the components to fit closely during plug-in and improves the firmness of the connection. The height of the first insertion strip 413 is matched with the height of the corresponding second slot 422, and the top surface inclination angle and shape of the first insertion strip 413 are matched with the bottom plate inclination angle and shape of the corresponding second groove 421, thereby ensuring the fit between the main support block 41 and the buffer support block 42 when they are staggered and plugged in from multiple dimensions, so that the entire support assembly 40 is structurally stable and reliable after assembly, and can better provide strong support for home appliances during transportation and storage.

[0046] It should be noted that the plug-in connection method of the main support block 41 and the buffer support block 42 can be quickly disassembled, which improves the assembly efficiency of the packaging base. It can also adjust the number, position and other parameters of the inserts and slots according to the size, weight and shape requirements of different home appliances or different accessories inside the same home appliance to achieve a flexible combination of the support assembly 40 and the buffer support block 42 to meet the diverse buffer support needs. For example, for a drum washing machine, the support assembly 40 innovatively sets a motor support pile 401, a bucket support pile 402 and a cement counterweight support pile 403 according to the characteristics and requirements of different components inside the drum washing machine, respectively providing accurate and stable support for key components such as the motor, bucket and cement counterweight inside the drum washing machine, ensuring the stability and safety of each component during transportation.

[0047] Reference Figure 8-9 The main support block 41 and the buffer support block 42 form a motor support stack 401. The main support block 41 extends from the bottom of the groove strip 31 of the inner frame assembly 30 to be limited and fixed. The buffer support block 42 is inserted from the top to form a support structure. While fitting the contact surface of the main support block 41, it can strongly support the motor of the drum washing machine. The top surface of the buffer support block 42 is a curved surface with different heights. The top surface shape of the buffer support block 42 matches the contour of the bottom or side of the motor of the home appliance, and can fit the home appliance tightly, providing more stable support, preventing the home appliance from shaking or shifting during transportation, and reducing the risk of damage due to collision. Figure 10-11 The main support block 41 and the buffer support block 42 form a water bucket support stack 402. The main support block 41 extends from the bottom of the groove strip 31 of the inner frame assembly 30 to be limited and fixed. The buffer support block 42 is inserted from the top to form a support structure. While fitting the contact surface of the main support block 41, it can strongly support the water bucket of the drum washing machine. The top surface of the buffer support block 42 is a curved surface and a avoidance groove 13. The top surface shape of the buffer support block 42 matches the contour of the bottom or side of the water bucket of the home appliance, and can fit the home appliance tightly, providing more stable support, preventing the home appliance from shaking or shifting during transportation, and reducing the risk of damage due to collision. Refer to Figure 12-13 The main support block 41 and the buffer support block 42 form a cement counterweight support pile 403. The main support block 41 extends from the bottom of the groove strip 31 of the inner frame assembly 30 to be limited and fixed, and the buffer support block 42 is inserted from the top to form a support structure. While fitting the contact surface of the main support block 41, it can strongly support the cement counterweight of the drum washing machine. The top surface of the buffer support block 42 is a flat inclined surface. The top surface shape of the buffer support block 42 matches the contour of the bottom or side of the cement counterweight of the home appliance, which can fit the home appliance tightly, provide more stable support, prevent the home appliance from shaking or displacement during transportation, and reduce the risk of damage due to collision.

[0048] When the length of the main support block 41 is too large, in order to prevent the first groove 411 from being greatly deformed and broken due to the stress not being well balanced and released when receiving the impact force, the stability of the support of the main support block 41 is affected. Figure 4-Figure 7 , Figure 12-13 A multi-directional limiting groove 414 is provided at the bottom of the main support block 41 composed of the first grooves 411 and laterally penetrates the plurality of first grooves 411. After the main support block 41 provided with the multi-directional limiting groove 414 at the bottom is fixed on the inner frame assembly 30, a multi-directional limiting plate 44 adapted to the multi-directional limiting groove 414 is extended from the bottom of the groove strip 31 of the inner frame assembly 30 and inserted into the multi-directional limiting groove 414 to limit and fix the main support block 41, thereby improving the connection stability between the main support block 41 and the inner frame assembly 30 and reducing the risk of deformation and fracture of the main support block 41 and the connection portion between the main support block 41 and the inner frame assembly 30 due to collision.

[0049] It should be noted that, because the bottom of the main support block 41 and the bottom of the inner frame assembly 30 are not on the same horizontal plane after the main support block 41 is connected to the inner frame assembly 30, in order to prevent the bottom of the main support block 41 from moving in the outer frame 20, a pad with holes matching the bottom of the main support block 41 can be placed between the inner frame assembly 30 and the outer frame 20. The multi-directional limit plate 44 can also be fixed on the pad.

[0050] The home appliance cushioning packaging base provided in this embodiment, when in use, insert the first groove 411 side plate of one or more main support blocks 41 along the groove strip 31 opened on the inner frame assembly 30 to achieve the initial horizontal limit of the main support block 41, ensuring that its position is accurate and not prone to left and right deviation; insert the elastic support member 43 from the fixing hole 32 opened on the inner frame assembly 30 to achieve the initial horizontal limit of the elastic support member 43, ensuring that its position is accurate and not prone to left and right deviation. The first groove 411 side plate of the main support block 41 extends from the bottom of the groove strip 31 opened on the inner frame assembly 30, further limiting and fixing, preventing the main support block 41 from falling off downward in the vertical direction, and providing a stable bottom support foundation for the entire support assembly 40; the elastic support member 43 extends from the bottom of the fixing hole 32 opened on the inner frame assembly 30, further limiting and fixing, preventing the elastic support member 43 from falling off downward in the vertical direction, and providing a stable bottom support foundation for the entire support assembly 40. Then, the second insertion strip 423 and the second slot 422 of the buffer support block 42 are connected to the first insertion strip 413 and the first slot 412 corresponding to the main support block 41, so as to realize the staggered connection between the main support block 41 and the buffer support block 42, and ensure that the two are tightly and firmly connected.

[0051] The protective strip 51 protects the bottom edge of the outer frame 20, the first protective fixing piece 52 tightly connects the adjacent protective strips 51 and protects the side edge of the outer frame 20, and the second protective fixing piece 53 connects the protective strip 51 and the first protective fixing piece 52 to strengthen the connection stability between the adjacent protective strips 51 and the first protective fixing piece 52, and together construct an indestructible protective system to prevent the outer frame 20 from falling apart.

[0052] The inner frame assembly 30 with the support assembly 40 installed is placed as a whole in the outer frame 20, and the nesting is achieved through the size design of the inner and outer frames 20. A passive smart tag is fixed on the base to facilitate tracking and management of home appliances, thereby completing the installation of the base.

[0053] It should be noted that the outer frame 20 can also be an integrally formed outer frame 20 produced by open mold injection molding. There is no need for the protective component 50 to connect and fix the components of the outer frame 20. The outer frame 20 can be formed into a box body with an opening upward to place the inner frame component 30, thereby reducing manufacturing and processing costs.

[0054] Embodiment 3 On the basis of the first and second embodiments, when the outer frame 20 and the inner frame assembly 30 are designed as separate parts, the outer frame 20 and the inner frame assembly 30 are mainly composed of multi-layered slotted hollow plates. When the bottom bracket is subjected to a drop impact, the outer impact force is absorbed layer by layer to prevent the impact force from directly acting on the home appliance body, thereby avoiding damage to the body. Specifically, in an optional embodiment, refer to Figure 1-Figure 5 The outer frame 20 includes a first outer panel 21, a first outer side panel 22 fixed on two opposite sides of the first outer panel 21, and a second outer side panel 23 fixed on the other opposite sides of the first outer panel 21, and the first outer side panel 22 is connected to the second outer side panel 23.

[0055] The inner frame assembly 30 is placed in the outer frame 20, and the inner frame assembly 30 includes a first inner frame, a third inner frame, and a second inner frame connecting the first inner frame and the third inner frame. The first inner frame includes a first inner panel 33 and a first inner side panel 331 fixed on opposite sides of the first inner panel 33, and the first inner side panel 331 is attached to the first outer side panel 22; the second inner frame includes a second inner panel 34 and a second inner side panel 341 fixed on opposite sides of the second inner panel 34, the second inner panel 34 is located above the first inner panel 33 and connected to the first inner panel 33, the second inner side panel 341 is attached to the second outer side panel 23, and the first inner side panel 331 is connected to the second inner side panel 341; the third inner frame includes a third inner panel 35, and the third inner panel 35 is located above the second inner panel 34 and connected to the second inner panel 34. The inner frame assembly 30 is also provided with a groove strip 31 for adapting and connecting with the main support block 41 of the support assembly 40 to ensure the stable installation of the support assembly 40.

[0056] It is understandable that the outer frame 20 is connected by a first outer panel 21, a first outer panel 22 fixed on two opposite sides thereof, and a second outer panel 23 on the other opposite sides thereof, forming a box body with an opening upward, which serves as an overall shape constraint framework of the bottom bracket, and provides a stable external environment for the inner frame assembly 30 and the home appliance. When subjected to an impact, the outer frame 20 can limit the displacement of the inner frame assembly 30 and the home appliance by virtue of its structural integrity and sufficient bending strength, and prevent them from excessive shaking or falling out under the impact force. It can also be combined with a protective assembly 50 fixed circumferentially on the outer wall of the outer frame 20 to more effectively resist various external collisions and impacts.

[0057] The inner frame assembly 30 is made of a hollow plate, and the inner frame assembly 30 is placed in the outer frame 20 as a whole. The nesting is achieved through the size design of the inner and outer frames 20, wherein the inner size of the outer frame 20 is slightly larger than the outer size of the inner frame assembly 30, so that the inner frame assembly 30 can be smoothly placed in the outer frame 20 and positioned to a certain extent. When the remaining impact force is transmitted to the inner frame after the initial buffering of the outer frame 20, the inner frame absorbs and disperses the impact force again through its own multi-layer structure, groove strips 31, avoidance holes 11 and fixing holes 32. The impact force that ultimately acts on the home appliance body is effectively reduced by layered buffering to prevent the body from being damaged. Specifically, the first inner frame, the second inner frame and the third inner frame of the inner frame assembly 30 absorb and disperse the impact force in turn, just like a multi-stage shock absorption system, gradually weakening the impact force.

[0058] It should be noted that fixing holes 32 and groove strips 31 are provided on the second inner panel 34 and the third inner panel 35, and cooperate with the first inner panel 33 to fix the support assembly 40 on the inner frame assembly 30; avoidance holes 11 are provided on the second inner panel 34 and the third inner panel 35, and plug-in grooves 12 and avoidance grooves 13 are provided on the first inner side panel 331 and the second inner side panel 341 to meet different installation and use requirements. For example, for a drum washing machine, the avoidance holes 11 are used to place the four corners of the drum washing machine, the plug-in grooves 12 are used to insert the columns, and the avoidance grooves 13 are used to place the water outlet pipe of the drum washing machine.

[0059] When the home appliance buffer packaging base provided in this embodiment is used, the first groove 411 side panels of one or more main support blocks 41 are inserted along the groove strips 31 provided on the second inner panel 34 and the third inner panel 35 to connect the second inner frame and the third inner frame, so as to achieve preliminary positioning of the main support block 41 in the horizontal direction, ensuring that its position is accurate and not prone to left-right deviation; the elastic support member 43 is inserted from the fixing holes 32 provided on the second inner panel 34 and the third inner panel 35 to achieve preliminary positioning of the elastic support member 43 in the horizontal direction, ensuring that its position is accurate and not prone to left-right deviation. The side plate of the first groove 411 of the main support block 41 extends from the bottom of the groove strip 31 opened on the second inner panel 34 and the third inner panel 35, connects the first inner frame, the second inner frame and the third inner frame, and further limits and fixes the main support block 41 to prevent it from falling off downward in the vertical direction, providing a stable bottom support foundation for the entire support assembly 40; the elastic support member 43 extends from the bottom of the fixing hole 32 opened on the second inner panel 34 and the third inner panel 35, and further limits and fixes the elastic support member 43 to prevent it from falling off downward in the vertical direction, providing a stable bottom support foundation for the entire support assembly 40. Then, the second insertion strip 423 and the second slot 422 of the buffer support block 42 are connected to the first insertion strip 413 and the first slot 412 corresponding to the main support block 41, so as to realize the staggered insertion of the main support block 41 and the buffer support block 42, and ensure that the two are tightly and firmly connected.

[0060] The protective strip 51 protects the bottom edge of the outer frame 20, the first protective fixing piece 52 tightly connects the adjacent protective strips 51 and protects the side edge of the outer frame 20, and the second protective fixing piece 53 connects the protective strip 51 and the first protective fixing piece 52 to strengthen the connection stability between the adjacent protective strips 51 and the first protective fixing piece 52, and together construct an indestructible protective system to prevent the outer frame 20 from falling apart.

[0061] The inner frame assembly 30 with the support assembly 40 installed is placed as a whole in the outer frame 20, and the nesting is achieved through the size design of the inner and outer frames 20. A passive smart tag is fixed on the base to facilitate tracking and management of home appliances, thereby completing the installation of the base.

[0062] It should be noted that the outer frame 20 can also be an integrally formed outer frame 20 produced by open mold injection molding, so that the first outer panel 21, the two first outer panels 22 and the two second outer panels 23 are integrally formed, and there is no need for a protective component 50 to connect and fix the various components of the outer frame 20. The outer frame 20 can be formed into a box body with an opening upward to place the inner frame component 30, thereby reducing manufacturing and processing costs.

[0063] Embodiment 4 On the basis of the first and second embodiments, when the outer frame 20 and the inner frame assembly 30 are designed as an integral whole, the outer frame 20 and the inner frame assembly 30 are mainly composed of multiple layers of slotted hollow plates. When the base is subjected to a falling impact, the outer impact force is absorbed layer by layer to prevent the impact force from directly acting on the home appliance body, thereby avoiding damage to the body.

[0064] Reference Figure 1-Figure 2 , Figure 6-Figure 7 The outer frame 20 includes a second outer panel 24, a third outer panel 25 fixed on opposite sides of the second outer panel 24, and a connecting plate 26 fixed on opposite sides of the third outer panel 25; the inner frame assembly 30 includes a fourth inner frame and a fifth inner frame connected to the top surface of the fourth inner frame; the fourth inner frame includes a fourth inner panel 36 and a fourth inner panel 361 fixed on opposite sides of the fourth inner panel 36, the fourth inner panel 36 is located above the second outer panel 24 and connected to the second outer panel 24, and the opposite sides of the fourth inner panel 361 are connected to the connecting plate 26; the fifth inner frame includes a fifth inner panel 37, the fifth inner panel 37 is located above the fourth inner panel 36 and connected to the fourth inner panel 36.

[0065] It can be understood that the second outer panel 24, the third outer panel 25 and the connecting plate 26 of the outer frame 20 are connected to form a relatively stable external frame structure, the fourth inner frame and the fifth inner frame of the inner frame assembly 30 are connected to each other, and the fourth inner frame is connected to the second outer panel 24 of the outer frame 20 through the fourth inner panel 36, and the fourth inner side panel 361 is connected to the connecting plate 26, so that the inner frame assembly 30 is tightly combined with the outer frame 20 to form a bottom support. The groove strip 31 provided on the inner frame assembly 30 is adapted to be connected with the main support block 41 of the support assembly 40, further enhancing the stability of the internal structure. The support assembly 40 can fix and support the home appliance to prevent the home appliance from shaking or falling out during transportation.

[0066] It should be noted that the sizes of the outer frame 20 and the inner frame assembly 30 are matched when they are designed, so that the inner frame assembly 30 can be accurately nested inside the outer frame 20. During the assembly process, accurate positioning and alignment are used to ensure that the fourth inner panel 36 and the second outer panel 24, the fourth inner side panel 361 and the connecting plate 26 and other connecting parts can be correctly docked. The outer frame 20 and the inner frame assembly 30 are composed of hollow plates. When the bottom bracket is subjected to a falling impact, the multi-layer structure of the bottom bracket can play a buffering role. Each layer of hollow plate can absorb and disperse part of the impact force, just like a multi-layer shock-absorbing spring. The impact force is gradually weakened in the process of passing through the layers of hollow plates, thereby reducing the impact force that ultimately acts on the home appliance body and effectively preventing the body from being damaged.

[0067] It should be noted that fixing holes 32 and groove strips 31 are provided on the fourth inner panel 36 and the fifth inner panel 37, which cooperate with the second outer panel 24 to fix the support assembly 40 on the outer frame 20 and the inner frame assembly 30; avoidance holes 11 are provided on the fourth inner panel 36 and the fifth inner panel 37, and plug-in grooves 12 and avoidance grooves 13 are provided on the third outer panel 25 and the fourth inner panel 361 to meet different installation and use requirements. For example, for a drum washing machine, the avoidance holes 11 are used to place the four corners of the drum washing machine, the plug-in grooves 12 are used to insert the columns, and the avoidance grooves 13 are used to place the water outlet pipe of the drum washing machine.

[0068] When the household appliance cushioning packaging base provided in this embodiment is used, the first groove 411 side panels of one or more main support blocks 41 are inserted along the groove strips 31 provided on the fourth inner panel 36 and the fifth inner panel 37 to connect the fourth inner frame and the fifth inner frame, so as to achieve preliminary positioning of the main support block 41 in the horizontal direction, ensuring that the position thereof is accurate and not prone to left-right deviation; the elastic support member 43 is inserted from the fixing holes 32 provided on the fourth inner panel 36 and the fifth inner panel 37 to achieve preliminary positioning of the elastic support member 43 in the horizontal direction, ensuring that the position thereof is accurate and not prone to left-right deviation. The side plate of the first groove 411 of the main support block 41 extends from the bottom of the groove strip 31 opened on the fourth inner panel 36 and the fifth inner panel 37, connects the outer frame 20, the fourth inner frame and the fifth inner frame, and further limits and fixes the main support block 41 to prevent it from falling off downward in the vertical direction, providing a stable bottom support foundation for the entire support assembly 40; the elastic support member 43 extends from the bottom of the fixing hole 32 opened on the fourth inner panel 36 and the fifth inner panel 37, and further limits and fixes the elastic support member 43 to prevent it from falling off downward in the vertical direction, providing a stable bottom support foundation for the entire support assembly 40. Then, the second insertion strip 423 and the second slot 422 of the buffer support block 42 are connected to the first insertion strip 413 and the first slot 412 corresponding to the main support block 41, so as to realize the staggered insertion of the main support block 41 and the buffer support block 42, and ensure that the two are tightly and firmly connected.

[0069] The third outer plate 25 of the fourth inner frame with the support assembly 40 installed is connected to the connecting plate 26 of the outer frame 20, and nesting is achieved through the size design of the inner and outer frames 20. A passive smart tag is fixed on the base to facilitate tracking and management of home appliances, thereby completing the installation of the base.

[0070] The protection strip 51 protects the bottom edge of the base, the first protection fixing piece 52 tightly connects the adjacent protection strips 51 and protects the side edge of the base, the second protection fixing piece 53 connects the protection strip 51 and the first protection fixing piece 52, strengthens the connection stability between the adjacent protection strips 51 and the first protection fixing piece 52, and together constructs an indestructible protection system to prevent the base from falling apart.

[0071] The household appliance cushioning packaging base of the present invention has the following advantages: The hollow board made of environmentally friendly and recyclable polypropylene material has low cost for manufacturing home appliance cushioning packaging base. It only needs simple stamping, folding and fixing to form. The manufactured base can be recycled, and the cost of single packaging is low, thus achieving cost reduction. It complies with environmental protection policies, can be recycled and is environmentally friendly.

[0072] Passive smart tags can realize full-process intelligent monitoring; passive smart tags have the functions of positioning, road spectrum collection, impact data collection, excessive impact alarm, temperature and humidity collection and data transmission, ensuring that during the long-term sea transportation process, the transportation environment is monitored throughout the process and alarms are issued for extreme situations. Abnormal white appliances can be screened in advance before terminal delivery, and problem links can be identified to reduce cargo damage, improve customer satisfaction with receipt, and enhance brand reputation.

[0073] For the first time in the industry, hollow boards are used as cushioning materials, making full use of the advantages of hollow boards. Through structural design and board assembly, the same cushioning effect as foam materials can be achieved.
