[0052] The packaging assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0053] like Figure 1 and Figure 5 As shown, the packaging assembly 100 according to an embodiment of the present invention is used for an indoor unit of an air conditioner. The packaging assembly 100 is a degradable component and includes two first packaging structures 1 and a base 2.

[0054] Specifically, refer to the attached Figure 1 and attached Figure 2 As shown, the two first packaging structures 1 are suitable for being respectively arranged in the length direction of the air conditioner indoor unit (refer to the attached Figure 1 The two first packaging structures 1 and the base 2 are respectively arranged at both ends of the air-conditioning indoor unit in the longitudinal direction, and respectively cover the parts at both ends of the air-conditioning indoor unit in the longitudinal direction. The base 2 is arranged at the lower ends of the two first packaging structures 1 and is suitable for extending along the longitudinal direction of the air-conditioning indoor unit, and is used to support the air-conditioning indoor unit at the bottom of the air-conditioning indoor unit. It can be understood that the arrangement of the two first packaging structures 1 and the base 2 can jointly wrap the air-conditioning indoor unit in the middle, thereby improving the buffering effect of the packaging assembly 100 on the air-conditioning indoor unit. The combined use of the two first packaging structures 1 and the base 2 can jointly support and protect the air-conditioning indoor unit, reduce the damage to the air-conditioning indoor unit caused by collision, falling, etc., and ensure the safety of the air-conditioning indoor unit during transportation.

[0055] It can be understood that the packaging component 100 used for the air-conditioning indoor unit is a degradable part. Compared with the EPS (expanded polystyrene) foam used in packaging in the prior art, the packaging component 100 of the present invention adopts a zero-plastic design, which can make the packaging component 100 for packaging the air-conditioning indoor unit degradable and recyclable, in line with modern environmental protection trends and meet the requirements of environmental protection packaging regulations.

[0056] It should be noted that the packaging component 100 of the present invention is an assembly, and the incoming materials are integrated into one component, which can be directly used to package the air-conditioning indoor unit without on-site assembly. It can simplify the packaging process of the air-conditioning indoor unit and reduce the difficulty of packaging operations. Moreover, the packaging operation of the present invention is not much different from the EPS packaging solution in the prior art, and will not affect the production efficiency of the production line.

[0057] According to the packaging assembly 100 of the present invention, the packaging assembly 100 for the air conditioner indoor unit is biodegradable, making it biodegradable and recyclable, conforming to modern environmental trends and meeting environmentally friendly packaging regulations. Furthermore, the packaging assembly 100 includes two first packaging structures 1 and a base 2, which together support and protect the air conditioner indoor unit, reducing damage to the unit from collisions, falls, and other hazards, thereby ensuring its safety during transportation.

[0058] In some embodiments of the present invention, Figure 1 and attached Figure 2 As shown, the lower side of the first packaging structure 1 is open, and the base 2 is spliced ​​with the first packaging structure 1 to block the lower open opening 10 of the first packaging structure 1. This facilitates the placement of the air conditioner indoor unit within the space defined by the two first packaging structures 1 and the base 2, simplifying the process of packaging the air conditioner indoor unit with the packaging assembly 100 and reducing the difficulty of packaging the air conditioner indoor unit with the packaging assembly 100. For example, the air conditioner indoor unit can be placed on the base 2 first, and then the two first packaging structures 1 can be sequentially placed on both ends of the air conditioner indoor unit in the longitudinal direction. Alternatively, the air conditioner indoor unit can be inverted first, inserted from the lower side of the first packaging structure 1, and finally the base 2 can be used to block the lower open opening 10 of the first packaging structure 1 to prevent the air conditioner indoor unit from falling out.

[0059] In a further embodiment of the present invention, refer to the attached Figure 3 and attached Figure 4 As shown, the first packaging structure 1 includes a buffer component 101 and a second buffer member 13. The lower side of the buffer component 101 is open, and the buffer components 101 of the two first packaging structures 1 are open on one side facing each other. The second buffer member 13 is formed into an open ring and the opening is located at the bottom. The opening of the second buffer member 13 and the opening of the buffer component 101 are opposite and jointly form a lower side opening 10. Along the axial direction of the second buffer member 13 (refer to the attached Figure 3 The left and right directions shown in the figure), at least a part of the second buffer member 13 is arranged in the buffer assembly 101, and the second buffer members 13 of the two first packaging structures 1 are respectively located on the side of the buffer assemblies 101 of the two first packaging structures 1 facing each other, and one end of the air-conditioning indoor unit in the length direction is located on the inner side of the second buffer member 13. The arrangement of the second buffer member 13 can increase the length of the first packaging structure 1 along the length direction of the air-conditioning indoor unit, so that the force-bearing area of ​​the first packaging structure 1 is increased, the force is dispersed, and the impact energy can be absorbed when the air-conditioning indoor unit falls or is hit by external force, thereby ensuring the structural strength of the first packaging structure 1 and improving the stability of the packaging assembly 100, thereby increasing the contact area between the first packaging structure 1 and the air-conditioning indoor unit, and expanding the supporting effect and protective effect of the first packaging structure 1 on the air-conditioning indoor unit.

[0060] It should be noted that an open ring refers to a ring structure that is not completely closed.

[0061] In a further embodiment of the present invention, refer to the attached Figure 3 and attached Figure 4 As shown, the buffer assembly 101 includes a frame 11 and a first buffer member 12. The frame 11 is formed into an open ring with an opening at the bottom. The first buffer member 12 is arranged in the frame 11 and is located at one end of the frame 11 facing the second buffer member 13, and is used to block the axial direction of the frame 11 (see the attached Figure 4 The frame 11 wraps the first buffer member 12 in the middle, which can increase the force-bearing area of ​​the first buffer member 12 and improve the structural strength of the first buffer member 12 and the frame 11. The frame 11 and the first buffer member 12 can jointly support and protect the air-conditioning indoor unit, reduce the damage to the home appliance caused by collision, falling, etc., and ensure the safety of the home appliance during transportation.

[0062] In a further embodiment of the present invention, referring to the attached Figure 4 As shown, the frame 11 includes a side plate 111 and a bottom plate 112. The side plate 111 is formed into an open ring with the opening at the bottom. The bottom plate 112 is located inside the side plate 111. One end of the bottom plate 112 in the width direction is aligned with the axial direction of the side plate 111 (see attached Figure 4 The bottom plate 112 is connected to one end of the side plate 111 in the left and right directions as shown, the bottom plate 112 is perpendicular to the side plate 111, the bottom plate 112 extends from one end to the other end of the side plate 111 in the length direction, the first buffer member 12 is located between the second buffer member 13 and the bottom plate 112, the first buffer member 12 and the bottom plate 112 are stacked and connected, the bottom plate 112 is located on the side of the first buffer member 12 away from the air conditioner indoor unit, and the side plate 111 surrounds the air conditioner indoor unit, and can protect the air conditioner indoor unit from the circumferential direction.

[0063] Further, refer to the attached Figure 3 and attached Figure 4 As shown, the bottom plate 112 and the first buffer component 12 are stacked at one end of the length direction of the air-conditioning indoor unit, which can enhance the overall buffering strength of the first packaging structure 1 and protect it from one end of the length direction of the air-conditioning indoor unit. The side panels 111 and the bottom plate 112 together wrap the first buffer component 12 in the middle, so that the force-bearing area of ​​the first buffer component 12 is increased, the force is dispersed, the structural strength of the first packaging structure 1 is ensured, the stability of the first packaging structure 1 is improved, and the protection effect of the packaging component 100 for the air-conditioning indoor unit is improved.

[0064] In a specific example, see the attached Figure 4 As shown, the frame 11 is formed by bending a single piece of paper corner strip and secured with box nails, eliminating the need for multiple sub-components to be assembled. This facilitates the production and processing of the frame 11 and simplifies the assembly process of the first packaging structure 1. It should be noted that the frame 11 made of paper corner strips serves as the primary force bearing point against external impacts and falls, effectively protecting the corners of the air conditioner indoor unit and providing support for stacking.

[0065] In a further embodiment of the present invention, referring to the attached Figure 3 and attached Figure 4 As shown, the buffer assembly 101 also includes a third buffer component 14. Along the axial direction of the frame 11, the third buffer component 14 is arranged on the side of the frame 11 away from the first buffer component 12 and is located on the outside of the second buffer component 13. The third buffer component 14 extends along the circumferential direction of the frame 11 and is connected to the frame 11. The setting of the third buffer component 14 can strengthen the height of the frame 11 along the axial direction, improve the supporting effect of the first packaging structure 1 for the air-conditioning indoor unit, and the third buffer component 14 is arranged on the outside of the second buffer component 13, which can enhance the protection of the second buffer component 13 from the outside of the second buffer component 13.

[0066] In a further embodiment of the present invention, referring to the attached Figure 3 and attached Figure 4 As shown, the frame 11 has multiple corners, and the third buffer 14 includes multiple sub-buffers 141. The multiple sub-buffers 141 are respectively arranged at the multiple corners of the frame 11. Each sub-buffer 141 includes a first plate 142 and a second plate 143. The first plate 142 and the second plate 143 are angled with each other and are respectively aligned with the two adjacent sides of the frame 11 at the corresponding corners. The first plate 142 and the second plate 143 can respectively strengthen the second buffer 13 from the two adjacent sides of the frame 11, so that the force-bearing area of ​​the frame 11 and the second buffer 13 is increased, which can further buffer and protect the air-conditioning indoor unit, reduce the probability of the air-conditioning indoor unit being damaged during transportation, and ensure the safety of the air-conditioning indoor unit.

[0067] In a specific example, see the attached Figure 3 and attached Figure 4 As shown, the frame 11 has two corners, and the third buffer member 14 includes two sub-support members 134 . The two sub-support members 134 are respectively arranged at the two corners of the frame 11 , which can protect and strengthen the two corners of the frame 11 .

[0068] In a further embodiment of the present invention, the third cushioning member 14 is a paper corner strip. The paper corner strip protects the corners of the second cushioning member 13, strengthens the structural strength of the first packaging structure 1, and improves the protective effect of the packaging assembly 100 on the air conditioner indoor unit. Furthermore, the paper corner strip can replace wood, reducing resource waste. It is 100% recyclable and reusable, making it a green and environmentally friendly packaging material, further meeting the environmental protection requirements of the packaging assembly 100. It should be noted that the third cushioning member 14 made of the paper corner strip serves as the first force point to resist external impact and falls, effectively protecting the corners of the air conditioner indoor unit and providing support for stacking.

[0069] Furthermore, the third buffer member 14 is bonded to the frame 11. Bonding technology is a process of connecting two or more materials together through an adhesive or adhesive material. Bonding the third buffer member 14 to the frame 11 can achieve overall uniform force, avoid concentrated stress, and improve the connection strength between the third buffer member 14 and the frame 11; bonding can simplify the manufacturing process of the first packaging structure 1, reduce the production cost and production time of the first packaging structure 1; through bonding, materials can be used more effectively, the material utilization rate can be improved, and waste can be reduced; bonding can connect the third buffer member 14 to the frame 11 without adding too much weight, which contributes to the lightweight design of the first packaging structure 1 and improves the performance and efficiency of the packaging component 100.

[0070] Furthermore, the third buffer member 14 is bonded to the second buffer member 13. Bonding the third buffer member 14 to the second buffer member 13 can achieve overall uniform force, avoid concentrated stress, and improve the connection strength between the third buffer member 14 and the second buffer member 13; bonding can simplify the manufacturing process of the first packaging structure 1, reduce the production cost and production time of the first packaging structure 1; through bonding, materials can be used more effectively, improve material utilization rate, and reduce waste; bonding can connect the third buffer member 14 to the second buffer member 13 without adding too much weight, which contributes to the lightweight design of the first packaging structure 1 and improves the performance and efficiency of the packaging component 100.

[0071] In a further embodiment of the present invention, the frame 11 is a paper corner strip. The paper corner strip can protect the corners of the first buffer member 12, strengthen the structural strength of the first packaging structure 1, and improve the protective effect of the packaging assembly 100 on the air conditioner indoor unit. In addition, the paper corner strip can replace wood, reducing resource waste. It is 100% recyclable and reusable, making it a green and environmentally friendly packaging material, further meeting the environmental protection requirements of the packaging assembly 100. It should be noted that the frame 11 made of the paper corner strip is the first force point to resist external impact and falling, and can not only effectively protect the corners of the air conditioner indoor unit, but also provide stacking support.

[0072] Furthermore, the first buffer member 12 is a honeycomb cardboard, which is made based on the principle of the natural honeycomb structure. It is a new type of environmentally friendly and energy-saving material with a sandwich structure, which is made by connecting corrugated paper into countless hollow three-dimensional regular hexagons by gluing to form an integral load-bearing member - the paper core, and gluing surface paper on both sides.

[0073] Compared to other sheet materials, the honeycomb sandwich structure offers a superior strength-to-mass ratio, resulting in a favorable performance-to-price ratio for its finished product. This allows the first cushioning member 12 to be lightweight, require minimal material, and be low-cost, contributing to the lightweight design of the first packaging structure 1 and reducing the manufacturing cost of the packaging assembly 100. Furthermore, the honeycomb sandwich structure is nearly isotropic, exhibits excellent structural stability, is resistant to deformation, exhibits high strength, and has a smooth surface, offering excellent compressive and bending resistance. This ensures that the first packaging structure 1 effectively protects the air conditioner indoor unit and reduces the risk of damage during distribution.

[0074] It should be noted that honeycomb paperboard is made of a flexible paper core and face paper, and has excellent toughness and resilience. Its unique honeycomb sandwich structure provides excellent cushioning performance and has the highest energy absorption per unit volume among all cushioning materials. High-thickness honeycomb paperboard can replace the EPS (expanded polystyrene) plastic foam cushions widely used in existing technologies. While ensuring impact resistance and cushioning properties, it also achieves the biodegradability of the first cushioning member 12, making it 100% recyclable after use, in line with modern environmental trends and meeting environmental requirements.

[0082] In a further embodiment of the present invention, referring to the attached Figure 8 As shown, the buffer assembly 101 also includes an eighth buffer member 164, which is located between the second buffer member 13 and the fifth buffer member 161. The eighth buffer member 164 is formed into an open ring, and the openings of the eighth buffer members 164 of the two first packaging structures 1 are located on the side of the two eighth buffer members 164 facing each other, so that the second buffer member 13 can be placed in the eighth buffer member 164. The setting of the eighth buffer member 164 can further improve the structural strength of the first packaging structure 1 and improve the stability of the packaging assembly 100, thereby increasing the contact area between the first packaging structure 1 and the air-conditioning indoor unit, and expanding the support effect and protection effect of the first packaging structure 1 for the air-conditioning indoor unit.

[0083] Preferably, the eighth buffer member 164 is corrugated cardboard. Corrugated cardboard is a multi-layer adhesive body composed of at least one layer of corrugated core paper (commonly known as "corrugated paper," "corrugated core paper," "corrugated paper core," or "corrugated base paper") and one layer of cardboard (also known as "boxboard" or "boxboard"). It has high mechanical strength and can withstand collisions and falls during transportation. This ensures that the first packaging structure 1 provides protection for the air conditioner indoor unit and reduces the damage rate of the air conditioner indoor unit during transportation. Optionally, the corrugated cardboard can be single-corrugated cardboard or double-corrugated cardboard to meet different strength requirements.

[0084] It should be noted that the eighth buffer member 164 can be formed in one page, which is easy to produce and process without additional bonding.

This ensures that the first packaging structure 1 effectively protects the air conditioner indoor unit and reduces the damage rate of the air conditioner indoor unit during transportation. Alternatively, the corrugated cardboard can be single-corrugated or double-corrugated to meet different strength requirements.

[0087] Furthermore, the seventh cushioning member 163 is a paper corner strip, which protects the corners of the sixth cushioning member 162, strengthens the structural strength of the first packaging structure 1, and enhances the protective effect of the packaging assembly 100 on the air conditioner indoor unit. Furthermore, the paper corner strip can replace wood, reducing resource waste and being 100% recyclable, making it a green and environmentally friendly packaging material, further meeting the environmental protection requirements of the packaging assembly 100. It should be noted that the seventh cushioning member 163, made of paper corner strips, serves as the primary force bearing point against external impacts and falls, effectively protecting the corners of the air conditioner indoor unit and providing support for stacking.

[0088] It should be noted that the fifth buffer member 161 is formed in one sheet, which is convenient to produce and process, and does not require additional bonding. The rigidity of the paper corner strip and the vertical compressive strength of the corrugated cardboard can effectively protect the corners from falling and serve as a stacking support.

[0089] Furthermore, the fifth buffer member 161 and the sixth buffer member 162 are bonded and connected. Bonding the fifth buffer member 161 and the sixth buffer member 162 can achieve overall uniform force, avoid concentrated stress, and improve the connection strength between the fifth buffer member 161 and the sixth buffer member 162; bonding can simplify the manufacturing process of the first packaging structure 1, reduce the production cost and production time of the first packaging structure 1; through bonding, materials can be used more effectively, improve material utilization rate, and reduce waste; bonding can connect the fifth buffer member 161 and the sixth buffer member 162 without adding too much weight, which contributes to the lightweight design of the first packaging structure 1 and improves the performance and efficiency of the packaging component 100.

[0092] In a further embodiment of the present invention, referring to the attached Figure 3 and attached Figure 4As shown, the first packaging structure 1 also includes a fourth buffer part 15, which is arranged in the second buffer part 13. The fourth buffer part 15 and the buffer assembly 101 are stacked and connected along the axial direction of the second buffer part 13, which can increase the overall buffering strength of the first packaging structure 1 and protect the air-conditioning indoor unit from one end in the length direction.

[0093] Further, refer to the attached Figure 3 and attached Figure 4 As shown, the buffer assembly 101 has a hand hole 121, and the hand hole 121 is along the length direction of the air conditioner indoor unit (refer to the attached Figure 4 The fourth buffer component 15 is provided with an avoidance gap 151 opposite to and connected to the hand hole 121 to facilitate the insertion of a hand, making the design of the hand hole 121 effective.

[0094] In a further embodiment of the present invention, the fourth buffer member 15 is a honeycomb cardboard, which is made according to the principle of the natural honeycomb structure. It is a new type of environmentally friendly and energy-saving material with a sandwich structure, which is made by connecting corrugated paper into countless hollow three-dimensional regular hexagons by gluing to form an integral load-bearing member - the paper core, and gluing surface paper on both sides.

[0095] Compared to other sheet materials, the honeycomb sandwich structure offers a superior strength-to-mass ratio, resulting in a favorable performance-to-price ratio for its finished product. This allows the fourth cushioning member 15 to be lightweight, require minimal material, and be low-cost, contributing to the lightweight design of the first packaging structure 1 and reducing the manufacturing cost of the packaging assembly 100. Furthermore, the honeycomb sandwich structure is nearly isotropic, offers excellent structural stability, resists deformation, possesses high strength, and has a smooth surface, offering excellent compressive and bending resistance. This ensures that the first packaging structure 1 effectively protects the air conditioner indoor unit and reduces the risk of damage during distribution.

[0096] It should be noted that honeycomb paperboard is made of a flexible paper core and face paper, exhibiting excellent toughness and resilience. Its unique honeycomb sandwich structure provides excellent cushioning performance, boasting the highest energy absorption per unit volume among all cushioning materials. High-thickness honeycomb paperboard can replace the EPS (expanded polystyrene) plastic foam cushioning pads widely used in existing technologies. While maintaining impact resistance and cushioning properties, it also achieves the degradability of the fourth cushioning member 15, making it 100% recyclable after use. This conforms to modern environmental trends and meets environmental requirements. Optionally, the fourth cushioning member 15 can be made of either high-density honeycomb paperboard or ordinary honeycomb paperboard.

[0097] Furthermore, the fourth buffer part 15 is bonded to the buffer component 101.

[0099] In a further embodiment of the present invention, referring to the attached Figure 6 and attached Figure 7As shown, the first packaging structure 1 also includes a ninth buffer member 17, which is arranged in the second buffer member 13. The ninth buffer member 17 is located on the side of the fourth buffer member 15 away from the buffer assembly 101. The ninth buffer member 17 is formed into an open ring, and the openings of the ninth buffer members 17 of the two first packaging structures 1 are located on the side of the two ninth buffer members 17 facing each other, which can facilitate the placement of the air-conditioning indoor unit into the ninth buffer member 17. The setting of the ninth buffer member 17 can further improve the structural strength of the first packaging structure 1 and improve the stability of the packaging assembly 100, thereby increasing the contact area between the first packaging structure 1 and the air-conditioning indoor unit, and expanding the support and protection effects of the first packaging structure 1 on the air-conditioning indoor unit.

[0100] In a specific example, see the attached Figure 8 As shown, along the left and right directions (such as Figure 8 As shown), the sixth buffer 162, the fifth buffer 161, the eighth buffer 164, the fourth buffer 15 and the ninth buffer 17 are stacked, which can protect the air-conditioning indoor unit from both ends of the length direction of the air-conditioning indoor unit, disperse the collision force, and ensure the safety of the air-conditioning indoor unit during transportation.

[0101] Preferably, the ninth buffer member 17 is kraft paper, which is also called box board paper or kraft paper. It is one of the main types of paper used for cartons. Kraft paper has a tough texture, high burst resistance, high ring pressure strength, good tear resistance, and high water resistance. It can ensure that the ninth buffer member 17 has a tough texture, good tear resistance, and good water resistance, and can play a good load-bearing role. By utilizing the toughness of the kraft paper, the ninth buffer member 17 is used as the first contact point of the air-conditioning indoor unit, reducing the probability of external force penetrating the honeycomb paperboard and improving the stability of the first packaging structure 1.

[0102] In a further embodiment of the present invention, referring to the attached Figure 3 and attached Figure 4 As shown, the second buffer member 13 includes a plurality of sub-plates 131 spliced ​​along the circumferential direction of the second buffer member 13. The plurality of sub-plates 131 are arranged along the circumferential direction of the second buffer member 13 to facilitate the production and manufacturing of the buffer assembly 101 and reduce the difficulty of producing and manufacturing the first packaging structure 1.

[0103] In a further embodiment of the present invention, referring to the attached Figure 3 and attached Figure 4 As shown, the plurality of sub-boards 131 include a support plate 132 at the top, which can protect the top of the air conditioner indoor unit. The lower surface of the support plate 132 is provided with a support member 134, which is used to stop against the front panel of the air conditioner indoor unit in the direction from top to bottom (such as Figure 4As shown in the figure, the wall surface of the support member 134 opposite to the front panel is inclined toward the front side, so that the support member 134 can fit the shape of the front panel, and can play a role in supporting the front panel when the air-conditioning indoor unit accidentally falls, so that the first packaging structure 1 is evenly stressed as a whole, reducing stress concentration in the air-conditioning indoor unit and reducing plastic deformation of plastic parts of the air-conditioning indoor unit.

[0104] Specifically, refer to the attached Figure 3 and attached Figure 4 As shown, the sub-plate 131 includes a support plate 132 and a fifth plate 133. The support plate 132 is arranged along the width direction of the air conditioner indoor unit (see the attached FIG. Figure 4 The fifth plate 133 extends in the vertical direction of the air conditioner indoor unit (as shown in the front and rear directions). Figure 4 The two fifth plates 133 extend along the length direction of the support plate 132 (see the attached Figure 4 The two fifth plates 133 are spaced apart in the front-to-back direction (as shown), and the ends of the two fifth plates 133 facing away from the base 2 are both against the support plate 132.

[0105] In a further embodiment of the present invention, the support plate 132 is a honeycomb cardboard, which is made based on the principle of the natural honeycomb structure. It is a new type of environmentally friendly and energy-saving sandwich structure material made by connecting corrugated paper into countless hollow three-dimensional regular hexagons using glue to form an integral load-bearing member - the paper core, and gluing surface paper on both sides.

[0106] Compared to other sheet materials, the honeycomb sandwich structure offers a superior strength-to-mass ratio, resulting in a favorable performance-to-price ratio for its finished product. This allows the support plate 132 to be lightweight, require minimal materials, and be low-cost, facilitating the lightweight design of the first packaging structure 1 and reducing the manufacturing cost of the packaging assembly 100. Furthermore, the honeycomb sandwich structure is nearly isotropic, exhibits excellent structural stability, is resistant to deformation, exhibits high strength, and has a smooth surface. It also offers excellent compressive and bending resistance, ensuring the first packaging structure 1 effectively protects the air conditioner indoor unit and reducing the risk of damage during distribution.

[0107] It should be noted that honeycomb paperboard is made of a flexible paper core and face paper, exhibiting excellent toughness and resilience. Its unique honeycomb sandwich structure provides excellent cushioning performance, boasting the highest energy absorption per unit volume among all cushioning materials. High-thickness honeycomb paperboard can replace the EPS (expanded polystyrene) plastic foam cushioning pads widely used in existing technologies. While maintaining impact resistance and cushioning properties, it also achieves the degradability of support plate 132, making it 100% recyclable after use. This conforms to modern environmental trends and meets environmental requirements. Optionally, support plate 132 can be made of either high-density honeycomb paperboard or standard honeycomb paperboard.

[0108] Furthermore, the support member 134 is made of corrugated cardboard. Corrugated cardboard is a multi-layer adhesive body consisting of at least one layer of corrugated core paper (commonly known as "corrugated sheet," "corrugated paper," "corrugated core paper," "corrugated paper core," or "corrugated base paper") and one layer of cardboard (also known as "boxboard" or "boxboard").

[0110] In a further embodiment of the present invention, the second buffer member 13 is a honeycomb cardboard, which is made based on the principle of the natural honeycomb structure. It is a new type of environmentally friendly and energy-saving material with a sandwich structure, which is made by connecting corrugated paper into countless hollow three-dimensional regular hexagons using glue to form an integral load-bearing member - the paper core, and gluing surface paper on both sides.

[0111] Compared to other sheet materials, the honeycomb sandwich structure offers a superior strength-to-mass ratio, resulting in a favorable performance-to-price ratio for its finished product. This allows the second cushioning member 13 to be lightweight, require minimal material, and be low-cost, contributing to the lightweight design of the first packaging structure 1 and reducing the manufacturing cost of the packaging assembly 100. Furthermore, the honeycomb sandwich structure is nearly isotropic, exhibits excellent structural stability, is resistant to deformation, exhibits high strength, and has a smooth surface. It also offers excellent compressive and bending resistance, ensuring the first packaging structure 1 effectively protects the air conditioner indoor unit and reducing the risk of damage during distribution.

[0112] It should be noted that honeycomb paperboard is made of a flexible paper core and face paper, and has good toughness and resilience. Its unique honeycomb sandwich structure provides excellent cushioning performance and has the highest energy absorption per unit volume among all cushioning materials. The high-thickness honeycomb paperboard can replace the EPS (expanded polystyrene) plastic foam cushions widely used in the existing technology. While ensuring impact resistance and cushioning properties, it also achieves the degradability of the second cushioning member 13, making it 100% recyclable after use, conforming to modern environmental trends and meeting environmental protection requirements. Optionally, the second cushioning member 13 can be made of high-density honeycomb paperboard or ordinary honeycomb paperboard.

[0113] It should be noted that the cushioning effect of the corrugated cardboard combined with the flat compression strength of the honeycomb cardboard can provide the first packaging structure 1 with overall cushioning performance, absorbing the impact energy when the air conditioner indoor unit falls, and meeting the requirements of side falls.

[0114] Furthermore, the second buffer part 13 is bonded to the buffer component 101. Bonding the second buffer part 13 to the buffer component 101 can achieve overall uniform force, avoid concentrated stress, and improve the connection strength between the second buffer part 13 and the buffer component 101; bonding can simplify the manufacturing process of the first packaging structure 1, reduce the production cost and production time of the first packaging structure 1; through bonding, materials can be used more effectively, improve material utilization rate, and reduce waste; bonding can connect the second buffer part 13 to the buffer component 101 without adding too much weight, which contributes to the lightweight design of the first packaging structure 1 and improves the performance and efficiency of the packaging component 100.

[0115] In a further embodiment of the present invention, referring to the attached Figure 2 and attached Figure 3 As shown, the base 2 includes a third plate 21 and a fourth plate 22. The third plate 21 extends along the length direction of the air conditioner indoor unit and is used to block the lower open openings 10 of the two first packaging structures 1. The fourth plate 22 is multiple and is stacked with the third plate 21. The multiple fourth plates 22 extend along the length direction of the third plate 21 (see attached Figure 3 The third plate 21 is arranged to support the air-conditioning indoor unit and play a bottom protection role. The fourth plate 22 is arranged to play a buffering role when the air-conditioning indoor unit accidentally falls, thereby minimizing the damage to the air-conditioning indoor unit and reducing the damage to the air-conditioning indoor unit.

[0116] In a further embodiment of the present invention, referring to the attached Figure 3 and attached Figure 4As shown, there are two fourth plates 22 and both are arranged on the lower side of the third plate 21. The two fourth plates 22 are respectively arranged at both ends of the length direction of the third plate 21. The third plate 21 can directly contact the lower side of the air-conditioning indoor unit to better support the air-conditioning indoor unit. The fourth plate 22 can play a buffering role on the lower side of the third plate 21. When the air-conditioning indoor unit accidentally falls or is hit by external force, the fourth plate 22 can contact the impact surface first, reduce the collision force transmitted to the third plate 21, and thereby reduce the damage to the air-conditioning indoor unit and reduce damage to the air-conditioning indoor unit.

[0117] In some embodiments of the present invention, Figure 7 and attached Figure 8 As shown, there are two fourth plates 22 and both are arranged on the upper side of the third plate 21. The two fourth plates 22 are respectively arranged at the two ends of the length direction of the third plate 21. The base 2 also includes a tenth buffer member 23. There are two tenth buffer members 23. The two tenth buffer members 23 are arranged in a one-to-one correspondence with the two fourth plates 22. It can be understood that the third plate 21 is not in direct contact with the bottom surface of the air-conditioning indoor unit. When the air-conditioning indoor unit accidentally falls or is hit by external force, the contact area between the packaging component 100 and the impact surface can be increased to better absorb the impact force, so that the collision force on the fourth plate 22 is greatly reduced. The setting of the tenth buffer member 23 can improve the structural strength of the fourth plate 22, ensure the stability of the fourth plate 22, and reduce the deformation of the fourth plate 22 due to the existence of the impact force, thereby ensuring the protective effect of the base 2 on the air-conditioning indoor unit and reducing the damage when the air-conditioning indoor unit accidentally falls.

[0118] Further, refer to the attached Figure 7 and attached Figure 8 As shown, the tenth buffer member 23 includes a second side plate 231 and a top plate 232. The second side plate 231 is formed into an open ring. The openings of the second side plates 231 of the two tenth buffer members 23 are located on the side of the two second side plates 231 facing each other, and the top plate 232 is located inside the second side plate 231. One end of the top plate 232 in the width direction is connected to one end of the second side plate 231 in the axial direction. The top plate 232 and the second side plate 231 are perpendicular to each other. The top plate 232 extends from one end of the second side plate 231 in the length direction to the other end. The fourth plate 22 is located between the third plate 21 and the top plate 232. The fourth plate 22 and the top plate 232 are stacked and connected. The top plate 232 is located on the side of the fourth plate 22 facing the air-conditioning indoor unit. The second side plate 231 surrounds the fourth plate 22 and can protect the air-conditioning indoor unit from the bottom.

[0119] Further, see the attached Figure 6As shown, the top plate 232, the fourth plate 22 and the third plate 21 are stacked on the lower side of the air-conditioning indoor unit, which can enhance the overall buffering strength of the base 2 and protect the air-conditioning indoor unit from the lower side. The top plate 232 and the second side plate 231 together wrap the fourth plate 22 in the middle, so that the force-bearing area of ​​the fourth plate 22 is increased, the force is dispersed, the structural strength of the base 2 is ensured, the stability of the base 2 is improved, and the protection effect of the packaging component 100 for the air-conditioning indoor unit is improved.

[0120] In a specific example, see the attached Figure 8 As shown, each tenth buffer member 23 is formed by bending a single piece of paper corner strip and secured with box nails, eliminating the need for multiple sub-components to be assembled. This facilitates the production and processing of the tenth buffer member 23 and simplifies the assembly process of the base 2. It should be noted that the tenth buffer member 23 supported by the paper corner strip serves as the primary force bearing point against external impacts and falls, effectively protecting the corners of the air conditioner indoor unit while also providing support for stacking.

[0121] In a further embodiment of the present invention, the third board 21 is honeycomb paperboard or corrugated paperboard. It is understood that when the third board 21 is honeycomb paperboard, it is manufactured based on the principles of a natural honeycomb structure. It is a novel, environmentally friendly, energy-saving sandwich material made by gluing corrugated paper together to form numerous hollow, three-dimensional regular hexagons, forming a single, load-bearing member—a paper core—with face paper glued to both sides.

[0122] Compared to other sheet materials, the honeycomb sandwich structure offers a superior strength-to-mass ratio, resulting in a favorable performance-to-price ratio for the finished product. This allows the third plate 21 to be lightweight, require minimal materials, and be low-cost, facilitating the lightweight design of the base 2 and reducing the manufacturing costs of the packaging assembly 100. Furthermore, the honeycomb sandwich structure is nearly isotropic, offers excellent structural stability, resists deformation, possesses high strength, and has a smooth surface, offering excellent compressive and bending resistance. This ensures that the base 2 effectively protects the air conditioner indoor unit and reduces the risk of damage during distribution.

[0123] It should be noted that honeycomb paperboard is made of a flexible paper core and face paper, exhibiting excellent toughness and resilience. Its unique honeycomb sandwich structure provides excellent cushioning performance, boasting the highest energy absorption per unit volume among all cushioning materials. High-thickness honeycomb paperboard can replace the EPS (expanded polystyrene) plastic foam cushioning pads widely used in existing technologies. While maintaining impact resistance and cushioning properties, the third board 21 is biodegradable, making it 100% recyclable after use, in line with modern environmental trends and meeting environmental requirements. Alternatively, the third board 21 can be made of either high-density honeycomb paperboard or standard honeycomb paperboard.

[0124] When the third plate 21 is a corrugated cardboard, the corrugated cardboard is a multi-layer adhesive body, which is composed of at least a layer of corrugated core paper (commonly known as "corrugated paper," "corrugated core paper," "corrugated paper core," or "corrugated base paper") and a layer of cardboard (also known as "boxboard" or "boxboard"). It has high mechanical strength and can withstand collisions and falls during transportation. It can ensure the protective effect of the first packaging structure 1 on the air conditioner indoor unit and reduce the damage rate of the air conditioner indoor unit during transportation. Optionally, the corrugated cardboard can be single corrugated cardboard or double corrugated cardboard to meet different strength requirements.

[0125] Furthermore, the fourth plate 22 is a honeycomb cardboard, which is made based on the principle of the natural honeycomb structure. It is a new type of environmentally friendly and energy-saving material with a sandwich structure, which is made by connecting corrugated paper into countless hollow three-dimensional regular hexagons using glue to form an integral load-bearing member - the paper core, and gluing surface paper on both sides.

[0126] Compared to other sheet materials, the honeycomb sandwich structure offers a superior strength-to-mass ratio, resulting in a favorable performance-to-price ratio for the finished product. This allows the fourth plate 22 to be lightweight, require minimal material, and be low-cost, facilitating the lightweight design of the base 2 and reducing the manufacturing cost of the packaging assembly 100. Furthermore, the honeycomb sandwich structure is nearly isotropic, exhibits excellent structural stability, resists deformation, exhibits high strength, and has a smooth surface. It also offers excellent compressive and bending resistance, ensuring that the base 2 effectively protects the air conditioner indoor unit and reducing the risk of damage during distribution.

[0127] It should be noted that honeycomb paperboard is made of a flexible paper core and face paper, exhibiting excellent toughness and resilience. Its unique honeycomb sandwich structure provides excellent cushioning performance, boasting the highest energy absorption per unit volume among all cushioning materials. High-thickness honeycomb paperboard can replace the EPS (expanded polystyrene) plastic foam cushioning pads widely used in existing technologies. While maintaining impact resistance and cushioning properties, the fourth panel 22 is biodegradable, making it 100% recyclable after use, in line with modern environmental trends and meeting environmental requirements. Alternatively, the fourth panel 22 can be made of either high-density honeycomb paperboard or standard honeycomb paperboard.

[0128] Furthermore, the third plate 21 and the fourth plate 22 are bonded together. Bonding the third plate 21 and the fourth plate 22 can achieve uniform stress on the whole, avoid concentrated stress, and improve the connection strength between the third plate 21 and the fourth plate 22; bonding can simplify the manufacturing process of the base 2, reduce the production cost and production time of the base 2; through bonding, materials can be used more effectively, improve material utilization rate, and reduce waste; bonding can connect the third plate 21 and the fourth plate 22 without adding too much weight, which contributes to the lightweight design of the base 2 and improves the performance and efficiency of the packaging component 100.

[0129] In some embodiments of the present invention, Figure 1 and attached Figure 2 As shown, the packaging assembly 100 also includes a second packaging structure 3, which is arranged between the two first packaging structures 1 and is used to cover the top wall and side wall of the air-conditioning indoor unit. It can be understood that the arrangement of the two first packaging structures 1 and the second packaging structure 3 can jointly wrap the top wall and side wall of the air-conditioning indoor unit, further improving the protective effect and supporting effect of the packaging assembly 100 for the air-conditioning indoor unit. The combined use of the two first packaging structures 1, the second packaging structure 3 and the base 2 can jointly support and protect the air-conditioning indoor unit, reduce the damage to the air-conditioning indoor unit caused by collision, falling, etc., and ensure the safety of the air-conditioning indoor unit during transportation.

[0130] In a further embodiment of the present invention, refer to the attached Figure 3 and attached Figure 4 As shown, the second packaging structure 3 includes an outer frame 31 and an inner frame 32. The outer frame 31 is formed into an open ring with the opening at the bottom, and the inner frame 32 is arranged on the inner side of the outer frame 31. The inner frame 32 is formed into an open ring with the opening at the bottom. The setting of the inner frame 32 ensures the buffering performance of the second packaging structure 3, and can absorb the impact energy when the air-conditioning indoor unit falls, reduce the damage to the air-conditioning indoor unit caused by collision, falling, etc., and ensure the safety of the air-conditioning indoor unit during transportation. The setting of the outer frame 31 can increase the compressive resistance in the vertical direction and improve the stacking support.

[0131] In a further embodiment of the present invention, referring to the attached Figure 3 and attached Figure 4As shown, at least one of the inner frame 32 and the outer frame 31 includes a plurality of sub-frames 321 spliced ​​and arranged along the circumferential direction of the inner frame 32. The plurality of sub-frames 321 are arranged along the circumferential direction of the inner frame 32 to facilitate the production of the inner frame 32 and reduce the difficulty of producing the second packaging structure 3. It is understandable that the inner frame 32 may include the plurality of sub-frames 321 spliced ​​and arranged along the circumferential direction of the inner frame 32, the outer frame 31 may include the plurality of sub-frames 321 spliced ​​and arranged along the circumferential direction of the inner frame 32, or both the inner frame 32 and the outer frame 31 may include the plurality of sub-frames 321 spliced ​​and arranged along the circumferential direction of the inner frame 32.

[0132] In a specific example, see the attached Figure 3 and attached Figure 4 As shown, the inner frame 32 includes three sub-frames 321 spliced ​​along the circumferential direction of the inner frame 32, and the three sub-frames 321 include a sixth plate 322 and two seventh plates 323. The sixth plate 322 extends along the width direction of the air conditioner indoor unit, and the two seventh plates 323 extend along the up-down direction of the air conditioner indoor unit and are in the length direction of the sixth plate 322 (see attached Figure 4 The sixth plate 322 is spaced apart in the front-to-back direction (as shown), and both ends of the sixth plate 322 in the length direction respectively abut against the ends of the two fifth plates 133 that are away from the base 2.

[0133] The cooperation between the inner frame 32 and the outer frame 31 can make up for the defect that the gap at the corner position is easy to fail, thereby increasing the circumferential impact resistance of the second packaging structure 3.

[0134] In a further embodiment of the present invention, the outer frame 31 is a composite cardboard. The composite cardboard is a laminated structural board made by gluing two thin surface boards to a thicker core layer. The material properties of different cardboards can be utilized to make the strength, rigidity, cushioning performance and other indicators of the outer frame 31 better, thereby improving the overall comprehensive performance of the outer frame 31.

[0135] Furthermore, the inner frame 32 is a honeycomb cardboard, which is made based on the principle of the natural honeycomb structure. It is a new type of environmentally friendly and energy-saving material with a sandwich structure, which is made by connecting corrugated paper into countless hollow three-dimensional regular hexagons using glue to form an integral load-bearing member - the paper core, and gluing surface paper on both sides.

[0136] Compared to other sheet materials, the honeycomb sandwich structure offers a superior strength-to-mass ratio, resulting in a favorable performance-to-price ratio for its finished products. This allows the inner frame 32 to be lightweight, utilize minimal materials, and achieve low cost, facilitating the lightweight design of the second packaging structure 3 and reducing the manufacturing cost of the packaging assembly 100. Furthermore, the honeycomb sandwich structure is nearly isotropic, exhibits excellent structural stability, is resistant to deformation, exhibits high strength, and has a smooth surface. It also offers excellent compressive and bending resistance, ensuring the protective effect of the second packaging structure 3 on the air conditioner indoor unit and reducing the risk of damage during distribution.

[0137] It should be noted that honeycomb paperboard is made of a flexible paper core and face paper, offering excellent toughness and resilience. Its unique honeycomb sandwich structure provides excellent cushioning performance, boasting the highest energy absorption per unit volume among all cushioning materials. High-thickness honeycomb paperboard can replace the EPS (expanded polystyrene) plastic foam cushioning commonly used in existing technologies. While maintaining impact resistance and cushioning properties, it also achieves a degradable inner frame 32, making it 100% recyclable after use. This conforms to modern environmental trends and meets environmental requirements. Alternatively, the inner frame 32 can be made of either high-density or standard honeycomb paperboard.

[0138] Furthermore, the outer frame 31 and the inner frame 32 are bonded together. Bonding the outer frame 31 and the inner frame 32 can achieve uniform stress on the whole, avoid concentrated stress, and improve the connection strength between the outer frame 31 and the inner frame 32; bonding can simplify the manufacturing process of the second packaging structure 3, reduce the production cost and production time of the second packaging structure 3; through bonding, materials can be used more effectively, improve material utilization rate, and reduce waste; bonding can connect the outer frame 31 and the inner frame 32 without adding too much weight, which contributes to the lightweight design of the second packaging structure 3 and improves the performance and efficiency of the packaging component 100.

[0139] It is understood that by leveraging the material properties of the individual components, the rigidity of the paper corner strips, the cushioning properties of the honeycomb paperboard, and the strength of the corrugated paperboard, the present invention provides the packaging assembly 100 with a relatively good overall load-bearing capacity, meeting various current packaging tests for air conditioner indoor units, such as dropping, clamping, stepping on, and stacking. Furthermore, the simple molding of the materials used ensures the production efficiency of the packaging assembly 100, thereby ensuring the production cost of the packaging assembly 100 and reducing the packaging cost of air conditioner indoor units. Furthermore, compared to the biodegradable materials used in some packaging structures in the prior art, the present invention has a relatively lower production cost.

[0140] It should be noted that some components made of honeycomb cardboard can also be replaced with corrugated cardboard. Corrugated cardboard is a multi-layer adhesive body consisting of at least one layer of corrugated core paper (commonly known as "corrugated paper," "corrugated core paper," "corrugated paper core," or "corrugated base paper") and one layer of cardboard (also known as "boxboard" or "boxboard"). It has high mechanical strength and can withstand collisions and falls during transportation. It can ensure the protection of the components for the air conditioner indoor unit and reduce the damage rate of the air conditioner indoor unit during transportation. Optionally, the corrugated cardboard can be single-corrugated cardboard or double-corrugated cardboard to meet different strength requirements.

[0141] Reference below Figures 1 to 8 The packaging assembly 100 according to two specific embodiments of the present invention is described. It is worth noting that the following description is merely exemplary and intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0142] Example 1

[0143] Specifically, if Figures 1 to 4 As shown, packaging assembly 100 is used for an air conditioner indoor unit. The packaging structure is biodegradable. Compared to the EPS (expanded polystyrene) foam used in prior art packaging, the packaging assembly 100 of the present invention adopts a zero-plastic design, making the packaging assembly 100 for the air conditioner indoor unit biodegradable and recyclable, conforming to modern environmental trends and meeting environmentally friendly packaging regulations. Packaging assembly 100 includes two first packaging structures 1, a base 2, and a second packaging structure 3.

[0144] Furthermore, the two first packaging structures 1 are suitable for being respectively arranged at the two ends of the length direction of the air-conditioning indoor unit and respectively covering the parts at the two ends of the length direction of the air-conditioning indoor unit. The lower side of the first packaging structure 1 is open, and the base 2 is spliced ​​with the two first packaging structures 1 to seal the lower open opening 10 of the first packaging structure 1. The base 2 extends along the length direction of the air-conditioning indoor unit and is used to support the air-conditioning indoor unit at the bottom of the air-conditioning indoor unit.

[0145] Furthermore, the first packaging structure 1 includes a buffer component 101, a second buffer part 13 and a fourth buffer part 15. The lower side of the buffer component 101 is open, and the side of the buffer components 101 of the two first packaging structures 1 facing each other is open. The buffer component 101 includes a frame 11, a first buffer part 12 and a third buffer part 14. The frame 11 is a paper corner strip and includes a side panel 111 and a bottom panel 112. The side panel 111 is formed into an open ring and the opening is located at the bottom. The bottom panel 112 is located inside the side panel 111. One end of the bottom panel 112 in the width direction is connected to one end of the side panel 111 in the axial direction. The bottom panel 112 is perpendicular to the side panel 111. The bottom panel 112 extends from one end of the side panel 111 in the length direction to the other end. The first buffer part 12 is a high-density honeycomb paperboard and is located between the second buffer part 13 and the bottom panel 112. The first buffer part 12 and the bottom panel 112 are stacked and adhesively connected to seal the open opening at one end of the axial direction of the frame 11.

[0146] Furthermore, the second buffer member 13 is formed into an open ring shape and the opening is located at the bottom. The second buffer member 13 is a high-density honeycomb cardboard. The opening of the second buffer member 13 and the opening of the buffer component 101 are opposite to each other and together form a lower open opening 10. Along the axial direction of the second buffer member 13, at least part of the second buffer member 13 is arranged in the buffer component 101. The second buffer members 13 of the two first packaging structures 1 are respectively located on the side of the buffer components 101 of the two first packaging structures 1 facing each other, and one end of the air-conditioning indoor unit in the length direction is located on the inner side of the second buffer member 13. The setting of the second buffer member 13 can increase the length of the first packaging structure 1 along the length direction of the air-conditioning indoor unit, so that the force-bearing area of ​​the first packaging structure 1 is increased and the force is dispersed. It can absorb the impact energy when the air-conditioning indoor unit falls or is hit by external force, ensure the structural strength of the first packaging structure 1, and improve the stability of the packaging component 100, thereby increasing the contact area between the first packaging structure 1 and the air-conditioning indoor unit, and expanding the support and protection effects of the first packaging structure 1 for the air-conditioning indoor unit.

[0147] Furthermore, the second buffer member 13 includes three sub-plates 131 spliced ​​along the circumferential direction of the frame 11, and the multiple sub-plates 131 are arranged along the circumferential direction of the frame 11. The three sub-plates 131 include a support plate 132 located at the top, and the support plate 132 is a double corrugated cardboard, which can protect the top of the air-conditioning indoor unit. The lower surface of the support plate 132 is provided with a support member 134, and the support member 134 is used to stop with the front panel of the air-conditioning indoor unit. In the direction from top to bottom, the wall surface of the support member 134 opposite to the front panel is inclined toward the front side, so that the support member 134 can fit the shape of the front panel, and can support the front panel when the air-conditioning indoor unit accidentally falls, so that the first packaging structure 1 is evenly stressed as a whole, reducing stress concentration in the air-conditioning indoor unit and reducing plastic deformation of plastic parts of the air-conditioning indoor unit.

[0148] Furthermore, along the axial direction of the frame 11, the third buffer 14 is a paper corner strip and is arranged on the side of the frame 11 away from the first buffer 12, and is located on the outside of the second buffer 13. The third buffer 14 extends along the circumferential direction of the frame 11 and is adhesively connected to the frame 11. The frame 11 has two corners. The third buffer 14 includes two sub-buffers 141. The two sub-buffers 141 are respectively arranged at the two corners of the frame 11. Each sub-buffer 141 includes a first plate 142 and a second plate 143. The first plate 142 and the second plate 143 are angled with each other and are respectively aligned with the two adjacent sides of the frame 11 at the corresponding corners. The first plate 142 and the second plate 143 can respectively strengthen the second buffer 13 from the two adjacent sides of the frame 11, thereby increasing the force-bearing area of ​​the frame 11 and the second buffer 13, which can further buffer and protect the air-conditioning indoor unit, reduce the probability of damage to the air-conditioning indoor unit during transportation, and ensure the safety of the air-conditioning indoor unit.

[0149] Furthermore, the fourth buffer component 15 is a high-density honeycomb cardboard and is arranged in the second buffer component 13. The fourth buffer component 15 and the buffer component 101 are stacked and adhesively connected along the axial direction of the second buffer component 13, which can increase the overall buffering strength of the first packaging structure 1 and protect the air-conditioning indoor unit from one end in the length direction. The buffer component 101 wraps the fourth buffer component 15 in the middle, so that the force-bearing area of ​​the fourth buffer component 15 is increased, the force is dispersed, the structural strength of the first packaging structure 1 is ensured, the stability of the first packaging structure 1 is improved, and the protective effect of the packaging component 100 for the air-conditioning indoor unit is improved.

[0150] Furthermore, the base 2 includes a third plate 21 and a fourth plate 22, both of which are high-density honeycomb cardboard. The third plate 21 extends along the length direction of the air-conditioning indoor unit and is used to seal the lower open openings 10 of the two first packaging structures 1. There are two fourth plates 22 and they are arranged on the lower side of the third plate 21. The two fourth plates 22 are spaced apart along the length direction of the third plate 21. The setting of the third plate 21 can support the air-conditioning indoor unit and play a bottom protection role. The setting of the fourth plate 22 can play a buffering role when the air-conditioning indoor unit accidentally falls, thereby reducing the damage to the air-conditioning indoor unit as much as possible and reducing the damage to the air-conditioning indoor unit.

[0151] Furthermore, the second packaging structure 3 is disposed between the two first packaging structures 1 and is used to cover the top and side walls of the air conditioner indoor unit. The second packaging structure 3 includes an outer frame 31 and an inner frame 32. The outer frame 31 is formed in an open ring shape with an opening at the bottom. The outer frame 31 is made of composite reinforced cardboard, and the inner frame 32 is made of high-density honeycomb cardboard. The inner frame 32 is disposed inside the outer frame 31 and is formed in an open ring shape with an opening at the bottom. The provision of the inner frame 32 ensures the cushioning performance of the second packaging structure 3, capable of absorbing the impact energy when the air conditioner indoor unit falls, reducing damage to the air conditioner indoor unit from collisions, falls, and other such damage, thereby ensuring the safety of the air conditioner indoor unit during transportation. The provision of the outer frame 31 can increase the vertical compressive strength and improve the stacking support. Furthermore, the inner frame 32 includes three sub-frames 321 spliced ​​and arranged along the circumference of the inner frame 32. The three sub-frames 321 are arranged along the circumference of the inner frame 32 to facilitate the production of the inner frame 32 and reduce the difficulty of manufacturing the second packaging structure 3.

[0152] In addition, the buffer component 101 has a hand hole 121, which passes through the buffer component 101 along the length direction of the air-conditioning indoor unit, allowing people to insert their hands to facilitate the transportation of the packaged air-conditioning indoor unit, thereby reducing the difficulty of transporting the air-conditioning indoor unit. The fourth buffer component 15 is provided with an avoidance notch 151 opposite to and connected to the hand hole 121, so as to facilitate the insertion of people's hands, making the design of the hand hole 121 effective.

[0153] It is understood that by leveraging the material properties of the individual components, the rigidity of the paper corner strips, the cushioning properties of the honeycomb paperboard, and the strength of the corrugated paperboard, the present invention provides the packaging assembly 100 with a relatively good overall load-bearing capacity, meeting various current packaging tests for air conditioner indoor units, such as dropping, clamping, stepping on, and stacking. Furthermore, the simple molding of the materials used ensures the production efficiency of the packaging assembly 100, thereby ensuring the production cost of the packaging assembly 100 and reducing the packaging cost of air conditioner indoor units. Furthermore, compared to the biodegradable materials used in some packaging structures in the prior art, the present invention has a relatively lower production cost.

[0154] Example 2

[0155] This embodiment is basically the same as the first embodiment, wherein the same components use the same names and marks. The only difference between the second embodiment and the first embodiment is that the buffer assembly 101 includes a fifth buffer member 161, a sixth buffer member 162, a seventh buffer member 163 and an eighth buffer member 164, the fifth buffer member 161 is a corrugated cardboard and is located on the outside of the second buffer member 13, the lower side of the fifth buffer member 161 is open, and the sides of the fifth buffer members 161 of the two first packaging structures 1 facing each other are open, which can facilitate the placement of the second buffer members 13 of the two first packaging structures 1 into the two fifth buffer members 161 respectively, further ensuring the structural strength of the first packaging structure 1, improving the stability of the packaging assembly 100, and expanding the protective effect of the first packaging structure 1 on the air-conditioning indoor unit, and can absorb the impact energy when the air-conditioning indoor unit falls or is hit by external force.

[0156] Furthermore, the sixth buffer member 162 is a corrugated cardboard. Along the axial direction of the second buffer member 13, the sixth buffer member 162 is located on the side of the fifth buffer member 161 away from the second buffer member 13. The fifth buffer members 161 of the two first packaging structures 1 are each provided with a sixth buffer member 162 on the side away from each other, thereby increasing the length of the first packaging structure 1 along the length direction of the air-conditioning indoor unit, thereby increasing the force-bearing area of ​​the first packaging structure 1 and dispersing the force. It can absorb the impact energy when the air-conditioning indoor unit falls or is hit by external force, thereby ensuring the structural strength of the first packaging structure 1 and improving the stability of the packaging assembly 100, thereby increasing the contact area between the first packaging structure 1 and the air-conditioning indoor unit, and expanding the support and protection effects of the first packaging structure 1 on the air-conditioning indoor unit.

[0157] Furthermore, the seventh buffer member 163 is a paper corner strip and there are two of them. The two seventh buffer members 163 are respectively located at the two ends of the sixth buffer member 162 in the front-to-back direction. The seventh buffer member 163 extends in the up-down direction and is connected to the sixth buffer member 162. The setting of the seventh buffer member 163 can increase the force-bearing area of ​​the sixth buffer member 162, and improve the structural strength of the sixth buffer member 162 and the fifth buffer member 161. The seventh buffer member 163, the sixth buffer member 162 and the fifth buffer member 161 can jointly support and protect the air-conditioning indoor unit, reduce the damage to home appliances caused by collisions, falls, etc., and ensure the safety of home appliances during transportation.

[0158] Furthermore, the seventh buffer member 163 includes a first side plate 1631 and a second side plate 1632. The first side plate 1631 is arranged on the side of the sixth buffer member 162 away from the fifth buffer member 161. The second side plate 1632 is located on the outside of the fifth buffer member 161 and is perpendicular to the first side plate 1631. One end of the second side plate 1632 in the width direction is connected to one end of the first side plate 1631 in the width direction. The first side plate 1631 and the second side plate 1632 both extend in the up and down directions. Along the length direction of the air-conditioning indoor unit, the first side plate 1631, the sixth buffer member 162 and the fifth buffer member 161 are stacked and connected. Along the front and back direction, the second side plate 1632 and the fifth buffer member 161 are stacked and connected, which can enhance the protection of the four corners of the air-conditioning indoor unit, disperse the collision force, and ensure the safety of household appliances during transportation.

[0159] Furthermore, the eighth buffer member 164 is a corrugated cardboard and is located between the second buffer member 13 and the fifth buffer member 161. The eighth buffer member 164 is formed into an open ring shape. The openings of the eighth buffer members 164 of the two first packaging structures 1 are located on the side of the two eighth buffer members 164 facing each other, so that the second buffer member 13 can be placed in the eighth buffer member 164. The setting of the eighth buffer member 164 can further improve the structural strength of the first packaging structure 1 and improve the stability of the packaging assembly 100, thereby increasing the contact area between the first packaging structure 1 and the air-conditioning indoor unit, and expanding the support and protection effects of the first packaging structure 1 on the air-conditioning indoor unit.

[0160] Furthermore, the first packaging structure 1 also includes a ninth buffer member 17, which is made of kraft paper and is arranged in the second buffer member 13. Along the left and right directions, the sixth buffer member 162, the fifth buffer member 161, the eighth buffer member 164, the fourth buffer member 15 and the ninth buffer member 17 are stacked. The ninth buffer member 17 is formed into an open ring, and the openings of the ninth buffer members 17 of the two first packaging structures 1 are located on the side of the two ninth buffer members 17 facing each other, which can facilitate the placement of the air-conditioning indoor unit into the ninth buffer member 17. The setting of the ninth buffer member 17 can further improve the structural strength of the first packaging structure 1 and improve the stability of the packaging assembly 100, thereby increasing the contact area between the first packaging structure 1 and the air-conditioning indoor unit, and expanding the support and protection effects of the first packaging structure 1 for the air-conditioning indoor unit.

[0161] Furthermore, there are two fourth plates 22 and both are arranged on the upper side of the third plate 21. The two fourth plates 22 are respectively arranged at both ends of the length direction of the third plate 21. The base 2 also includes a tenth buffer member 23. The tenth buffer member 23 is a paper corner strip and there are two of them. The two tenth buffer members 23 are arranged in a one-to-one correspondence with the two fourth plates 22. It can be understood that the third plate 21 is not in direct contact with the bottom surface of the air-conditioning indoor unit. When the air-conditioning indoor unit accidentally falls or is hit by external force, the contact area between the packaging component 100 and the impact surface can be increased to better absorb the impact force, so that the collision force on the fourth plate 22 is greatly reduced.
