Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and specifically, to a bottom packaging cushion assembly, a packaging assembly and a household electrical appliance assembly. Background Art

[0002] Currently, white pollution has been increasingly taken seriously by various countries. Countries and regions such as the European Union, India and Australia have successively introduced plastic restriction orders, imposing some restrictions and specific requirements on relevant plastic products in packaging materials. In particular, France has introduced regulations requiring that the packaging materials for some products in 2024 need to use green recyclable materials, and the use of commonly used plastic products such as packaging foam is prohibited for packaging.

[0003] Currently, as Figure 1 shown, the inner packaging materials of existing air conditioner products are all EPS packaging foams 100. For example, the outdoor unit 102 of an air conditioner adopts the form of upper and lower packaging foams. There is no feasible and mature green environmental protection packaging in the market, and there is an urgent need to introduce an effective green plastic-free packaging solution to replace the existing solution to meet the market needs. Since the outdoor unit of the air conditioner is relatively heavy and the chassis is an uneven curved surface, the weight is mainly supported by the two feet 103 of the air conditioner outdoor unit 102, resulting in characteristics such as concentrated stress on the packaging materials at the supporting feet 103, and higher requirements for packaging protection.

[0004] In addition, there is an existing honeycomb paper packaging structure and packaging assembly for the outdoor unit of an air conditioner. In this technical solution, the compressor feet are supported by honeycomb boards, without secondary buffering ability. After the honeycomb boards are crushed, dangerous situations such as the collapse of the machine are likely to occur during storage stacking. Moreover, the use of honeycomb board components does not solve the problem of easy breakage during incoming materials and turnover. In addition, there is no effective restraint for the placement of accessories, which is likely to cause the loss of accessories. Summary of the Utility Model

[0005] The first object of the utility model is to provide a bottom packaging cushion assembly that can not only provide strong support and still maintain sufficient support strength after drop impact while meeting the requirements of green plastic-free environmental protection, but also has a certain buffering and protection ability.

[0006] The second object of the utility model is to provide a packaging assembly that adopts the above-mentioned bottom packaging cushion assembly.

[0007] The third object of the utility model is to provide a household electrical appliance assembly that adopts the above-mentioned packaging assembly.

[0008] To achieve the above first object, the present utility model provides a bottom packaging cushion assembly, comprising: a corner guard frame, the corner guard frame includes a circumferential border and a bottom border both in a ring shape, and the circumferential border extends vertically upward from the outer edge of the bottom border; a honeycomb cardboard, the honeycomb cardboard is located inside the corner guard frame and covers the opening in the middle of the bottom border; a middle packaging cushion plate, the middle packaging cushion plate is arranged on the honeycomb cardboard and is located in the middle of the length direction of the honeycomb cardboard; support paper tubes, the number of the support paper tubes is more than two, at least one support paper tube is arranged at each of the two ends of the middle packaging cushion plate in the length direction, the support paper tubes all extend along the width direction of the honeycomb cardboard, the cross section of the support paper tube is rectangular, and a support portion is arranged on the top wall of the support paper tube.

[0009] As can be seen from the above solution, due to the heavy weight of the air conditioner outdoor unit itself, the chassis is an uneven curved surface, and the weight is mainly supported by the two feet of the outdoor unit, resulting in concentrated stress on the packaging materials at the support feet. This bottom packaging cushion assembly is provided with support paper tubes at the support parts such as the feet of the air conditioner outdoor unit, directly supports the feet with a square paper tube structure, and at the same time, a strengthened honeycomb cardboard is designed and used in cooperation under the square paper tube, which can play a certain buffering role, ensuring that it can not only provide strong support and still maintain sufficient support strength after a drop impact, but also has a certain buffering and protection ability, solving the problems of insufficient support and no secondary buffering ability in the prior art. At the same time, by pasting a whole piece of strengthened honeycomb cardboard on the inner side of the corner guard frame, and pasting other honeycomb cardboard such as the middle packaging cushion plate and the support paper tubes on the whole piece of honeycomb cardboard, the integrity of the overall structure is guaranteed. In addition, honeycomb cardboard products are prone to being knocked and damaged during turnover and production packaging. This technical solution designs a corner guard structure around the honeycomb cardboard to improve the overall structural strength.

[0010] A preferred solution is that the bottom packaging cushion assembly further includes a limit cushion plate, the limit cushion plate is pasted on the honeycomb cardboard and is arranged near the end of the length direction of the honeycomb cardboard, and the side wall of the limit cushion plate is attached to the support paper tube near it in the length direction.

[0011] Thus, the multi-layer cushion can further improve the support performance and buffering performance of the bottom packaging cushion assembly. At the same time, the limit cushion plate can be in limit cooperation with the support paper tube to prevent the support paper tube from shifting after being stressed.

[0012] A further solution is that the bottom packaging cushion assembly further includes a transverse cushion block, which is made of honeycomb paper; the transverse cushion block is arranged at the first end in the length direction of the honeycomb paperboard and extends along the width direction of the honeycomb paperboard, and the honeycomb direction of the transverse cushion block is parallel to the length direction; the first side wall of the transverse cushion block is attached to the inner surface of the circumferential frame, the bottom wall of the transverse cushion block is attached to the honeycomb paperboard, the second side wall of the transverse cushion block is attached to the side wall of the limit cushion plate far from the support paper tube, and the first side wall and the second side wall are arranged opposite to each other in the honeycomb direction of the transverse cushion block.

[0013] It can be seen that by arranging the transverse cushion block made of honeycomb paper on the side of the corner guard frame and pasting it on the circumferential frame inside the corner guard frame, the anti-clamping ability improved by the strong flat pressure of the honeycomb paperboard is fully utilized.

[0014] A further solution is that the bottom packaging cushion assembly further includes a longitudinal cushion block group, and the bottom wall of the longitudinal cushion block group is attached to the honeycomb paperboard; the longitudinal cushion block group is arranged at the end of the limit cushion plate in the width direction of the honeycomb paperboard; the two side walls of the longitudinal cushion block group in the width direction are respectively attached to the limit cushion plate and the circumferential frame; the two end walls of the longitudinal cushion block group in the length direction are respectively attached to the support paper tube and the circumferential frame close to the longitudinal cushion block group.

[0015] A further solution is that the number of the longitudinal cushion block groups is four, and the four longitudinal cushion block groups are respectively located at the four corners of the corner guard frame.

[0016] A further solution is that each longitudinal cushion block group includes two or more longitudinal cushion blocks that are parallel and attached along the width direction, and each longitudinal cushion block extends along the length direction of the honeycomb paperboard, and the honeycomb direction of the longitudinal cushion block is parallel to the width direction.

[0017] It can be seen that through the settings of the peripheral circumferential frame, honeycomb paperboard, and each transverse cushion block and longitudinal cushion block, etc., it is ensured that the product has strong anti-clamping force.

[0018] A further solution is that a drainage joint placement groove is provided on one of the longitudinal cushion block groups, and the drainage joint placement groove is located at the first end in the length direction of the honeycomb paperboard; this longitudinal cushion block group includes a first longitudinal cushion block and a second longitudinal cushion block, the first longitudinal cushion block is attached to the circumferential frame in the width direction; the length of the first longitudinal cushion block is less than the length of the second longitudinal cushion block; the drainage joint placement groove is surrounded by the honeycomb paperboard, the end wall of the first longitudinal cushion block, the side wall of the second longitudinal cushion block, and the circumferential frame.

[0019] It can be seen that the outdoor unit of an air conditioner is usually equipped with accessories such as binding tapes, drainage joints, and connecting pipes. The effective placement of the accessories can ensure the normal flow of the production line and avoid the loss of accessories caused by unreliable placement or inconvenient packaging, which affects the production efficiency. Based on the shape of the drainage joint equipped with the outdoor unit of the air conditioner, the bottom packaging cushion assembly is provided with a placement structure specifically for placing the drainage joint, overcoming the characteristic of the environmentally friendly packaging material that is not easy to process special shapes, and making a special design for the placement position of the accessories to ensure effective restraint on the accessories and avoid problems such as the drainage joint and other accessories being easily dropped on the production line or during the turnover process.

[0020] A preferred solution is that the two ends of the transverse cushion blocks are respectively attached to the side walls of two of the longitudinal cushion block groups; and / or the top surfaces of the transverse cushion blocks are all at the same height as the top surface of the circumferential frame; and / or the top surfaces of the longitudinal cushion block groups are all at the same height as the top surface of the circumferential frame.

[0021] It can be seen that the top surfaces of the longitudinal cushion block groups are all at the same height as the top surface of the circumferential frame. Using the high strength of the corner guard frame to wrap each honeycomb cardboard, it is ensured that during the stacking, incoming material turnover, transportation, and packaging processes, the circumferential frame can protect the components such as each cushion plate inside the corner guard frame from being damaged, and ensure the reliability and aesthetics of the materials.

[0022] A preferred solution is that the number of the limiting cushion plates is more than two, and at least one limiting cushion plate is respectively arranged at both ends in the length direction of the honeycomb cardboard.

[0023] A further solution is that the bottom packaging cushion assembly further includes an accessory accommodating cushion plate, and the accessory accommodating cushion plate extends along the width direction and is pasted on the limiting cushion plate close to the second end of the honeycomb cardboard; a binding tape placement groove is formed on the accessory accommodating cushion plate, and the binding tape placement groove is recessed downward from the top surface of the accessory accommodating cushion plate.

[0024] It can be seen that since accessories such as binding tapes need to be placed, it is necessary to ensure the thickness of the cushion plate provided with the accessory groove. By setting multiple thinner cushion plates laminated and pasted together, the problem that the flat compression strength decreases instead as the thickness of the honeycomb cardboard increases is solved. At the same time, based on the shapes of the drainage joint and the binding tape equipped with the outdoor unit of the air conditioner, a placement structure specifically for placing the drainage joint and the binding tape is set, overcoming the characteristic of the environmentally friendly packaging material that is not easy to process special shapes, and making a special design for the placement position of the accessories to ensure effective restraint on the accessories and avoid problems such as the accessories being easily dropped on the production line or during the turnover process. The binding tape placement groove can be formed by stamping process.

[0025] A further solution is that the bottom packaging cushion assembly further includes a supporting cushion plate, and the supporting cushion plate extends along the width direction and is pasted on the limiting cushion plate close to the second end of the honeycomb cardboard; in the length direction, the supporting cushion plate is located between the accessory accommodating cushion plate and the supporting paper tube.

[0026] A preferred solution is that the bottom border includes four bottom flanges connected end to end along the circumference of the corner guard frame; the circumferential border includes four side flanges connected end to end along the circumference of the corner guard frame; the width of the bottom flange is greater than the width of the side flange.

[0027] Thus, the wider width of the bottom flange results in a larger bottom support area for the product. At the same time, when fixed to the honeycomb cardboard with adhesive, the bonding area is larger, ensuring firm adhesion.

[0028] A further solution is that the length of the support paper tube is less than the distance between two relatively side flanges in the width direction.

[0029] Thus, it can be seen that the length of the support paper tube needs to be designed shorter than the base feet of the air conditioner outdoor unit. When the bottom edge in the length direction of the product is impacted by the outdoor unit, the base feet will not directly transfer the impact force to the bottom border of the corner guard frame through the support paper tube, preventing the middle position of the bottom border from being broken.

[0030] A preferred solution is that at least one of the middle packaging cushion plate, the support paper tube, and the limit cushion plate is made of honeycomb paper.

[0031] A preferred solution is that a base foot installation position is provided above the support part, and the width of the support part is greater than the width of the base foot installation position.

[0032] Thus, the base foot installation position is used to place the base feet of the air conditioner outdoor unit. The width of the support part on the support paper tube is greater than the width of the base foot installation position, ensuring that the extremely high support strength of the vertical side of the support paper tube can be fully exerted.

[0033] A preferred solution is that the thickness of the honeycomb cardboard is greater than or equal to 6 millimeters.

[0034] A preferred solution is that the top surface of the middle packaging cushion plate is lower than and close to the top surface of the circumferential border; and / or the top surface of the support paper tube is lower than the top surface of the middle packaging cushion plate; and / or a connection pipe accessory installation groove is formed between the middle packaging cushion plate and the circumferential border, and the connection pipe accessory installation groove extends along the length direction.

[0035] Thus, the connection pipe accessory installation groove is used to place the connection pipe accessories.

[0036] To achieve the above second object, the present utility model provides a packaging assembly, including a top packaging cushion component and the above bottom packaging cushion component arranged oppositely along the vertical direction.

[0037] Preferably, the top packaging cushion assembly includes a top paper frame and a cushion plate assembly. The top paper frame includes a top wall of the paper frame and a folded edge of the paper frame. The folded edge of the paper frame extends vertically downward from the outer edge of the top wall of the paper frame. The cushion plate assembly is located inside the top paper frame and is adhered to the folded edge of the paper frame.

[0038] Furthermore, the cushion plate assembly is made of honeycomb paper. The cushion plate assembly includes a first longitudinal cushion plate, a second longitudinal cushion plate, a first transverse cushion plate, and a second transverse cushion plate. The first longitudinal cushion plate and the second longitudinal cushion plate are arranged opposite to each other along the width direction of the top paper frame. The first transverse cushion plate and the second transverse cushion plate are arranged opposite to each other along the length direction of the top paper frame. The honeycomb directions of the first longitudinal cushion plate and the second longitudinal cushion plate are both parallel to the width direction of the top paper frame. The honeycomb direction of the first transverse cushion plate is parallel to the length direction of the top paper frame. The number of the second transverse cushion plates is more than two. Each of the second transverse cushion plates is stacked and adhered vertically. The honeycomb directions of each of the second transverse cushion plates are all parallel to the vertical direction.

[0039] It can be seen that the top paper frame can protect the internal cushion plate assembly. At the same time, the cushion plate assembly is adhered to the folded edge of the paper frame of the top paper frame, and the flat compression strength of the honeycomb cardboard is used to improve the anti-clamping ability of the product. For the relatively wide second transverse cushion plate, it is pasted flat. At the same time, in order to ensure the strength, more than two honeycomb cardboard can be used for composite pasting.

[0040] To achieve the above third object, the present utility model provides a household electrical appliance assembly, including a household electrical appliance and the above-mentioned packaging assembly. The household electrical appliance is fixed between the top packaging cushion assembly and the bottom packaging cushion assembly. Description of the Drawings

[0057] Technologies, methods, and devices known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0058] See Figure 2 and Figure 3 , the household electrical appliance assembly of this embodiment includes a household electrical appliance and a packaging assembly. The packaging assembly includes a top packaging cushion assembly 2 and a bottom packaging cushion assembly 3 that are oppositely arranged vertically. The household electrical appliance is fixed between the top packaging cushion assembly 2 and the bottom packaging cushion assembly 3. The household electrical appliance in this embodiment is an outdoor air conditioner 1, and the bottom of the outdoor air conditioner 1 has feet 11 for supporting the entire outdoor air conditioner 1.

[0059] See Figures 3 to 10 , the bottom packaging cushion assembly 3 includes a corner guard frame 4, honeycomb paperboard 5, a middle packaging cushion board 6, a support paper tube 7, a limit cushion board 8, a transverse cushion block 9, a longitudinal cushion block group 10, a support cushion board 12, and an accessory accommodation cushion board 13. In this embodiment, the corner guard frame 4, honeycomb paperboard 5, middle packaging cushion board 6, support paper tube 7, limit cushion board 8, transverse cushion block 9, longitudinal cushion block group 10, support cushion board 12, and accessory accommodation cushion board 13 are all made of honeycomb paper. In other embodiments, the corner guard frame 4, middle packaging cushion board 6, support paper tube 7, limit cushion board 8, transverse cushion block 9, longitudinal cushion block group 10, support cushion board 12, and accessory accommodation cushion board 13, etc. can also be made of other paperboards such as composite paperboard or corrugated paperboard.

[0060] The corner guard frame 4 includes a circumferential border 41 and a bottom border 42 that are both annular. The circumferential border 41 extends vertically upward from the outer edge of the bottom border 42. The bottom border 42 includes four bottom flanges 421 that are connected end to end along the circumference of the corner guard frame 4. The circumferential border 41 includes four side flanges 411 that are connected end to end along the circumference of the corner guard frame 4.

[0061] The honeycomb cardboard 5 is located inside the corner guard frame 4 and covers the opening 43 in the middle of the bottom border 42 surrounded by four bottom flanges 421. The edges around the honeycomb cardboard 5 are adhesively fixed to each bottom flange 421. The thickness of the honeycomb cardboard 5 is greater than or equal to 6 millimeters. The width of the bottom flange 421 of the corner guard frame 4 is greater than the width of the side flange 411. The wider bottom flange 421 results in a larger bottom support area for the product. At the same time, when adhesively fixed to the honeycomb cardboard 5, it has a larger bonding area, ensuring firm adhesion.

[0062] The middle packaging cushion plate 6, the support paper tube 7, the limit cushion plate 8, the transverse cushion block 9, and the longitudinal cushion block group 10 are all adhesively attached to the honeycomb cardboard 5.

[0063] The middle packaging cushion plate 6 is located in the middle of the honeycomb cardboard 5 in the length direction. The number of support paper tubes 7 is two, and the two support paper tubes 7 are respectively arranged at both ends of the middle packaging cushion plate 6 in the length direction of the honeycomb cardboard 5. The number of limit cushion plates 8 is two. One limit cushion plate 8 is arranged close to one support paper tube 7, and the limit cushion plate 8 is located on the side of the corresponding support paper tube 7 away from the middle packaging cushion plate 6 and is in contact with the corresponding support paper tube 7 in the length direction of the honeycomb cardboard 5. A connecting pipe accessory installation groove 44 is formed between the middle packaging cushion plate 6 and the circumferential border 41. The connecting pipe accessory installation groove 44 extends along the length direction of the honeycomb cardboard 5 and is used for placing a connecting pipe accessory (not shown).

[0064] The support paper tubes 7 all extend along the width direction of the honeycomb cardboard 5. The cross-section of the support paper tube 7 is rectangular. The top surface 61 of the middle packaging cushion plate 6 is lower and closer to the top surface 412 of the circumferential border 41. The top surface 73 of the support paper tube 7 is lower than the top surface 61 of the middle packaging cushion plate 6.

[0065] The top wall of the support paper tube 7 is provided with a support portion 71. Above the support portion 71, there is a base foot installation position 72, which is used for placing the base foot 11 of the air conditioner outdoor unit. The width of the support portion 71 is greater than the width of the base foot installation position 72, that is, the width of the support paper tube 7 is greater than the width of the base foot 11. In this way, it can ensure that the extremely high support strength of the vertical side of the support paper tube 7 is fully exerted.

[0066] The length of the support paper tube 7 is less than the distance between two relatively side flanges 411 in the width direction of the honeycomb cardboard 5. In this way, the length design of the support paper tube 7 can be shorter than the base foot 11 of the air conditioner outdoor unit 1, avoiding the situation that when the bottom edge in the length direction of the product is impacted by the outdoor unit, the base foot 11 directly transmits the impact force through the support paper tube 7 to the bottom border 42 of the corner guard frame 4, causing the middle position of the bottom border 42 to be broken.

[0067] The horizontal spacer 9 is made of honeycomb paper. The horizontal spacer 9 is arranged at the first end of the honeycomb paperboard 5 in the length direction and extends along the width direction of the honeycomb paperboard 5. The honeycomb direction of the horizontal spacer 9 is parallel to the length direction of the honeycomb paperboard 5. The honeycomb direction refers to the through direction of the honeycomb holes. The first side wall 91 of the horizontal spacer 9 fits against the inner surface of the circumferential border 41. The bottom wall 93 of the horizontal spacer 9 fits against the honeycomb paperboard 5. The second side wall 92 of the horizontal spacer 9 fits against the side wall of the limit backing plate 8 away from the support paper tube 7. The first side wall 91 and the second side wall 92 of the horizontal spacer 9 are oppositely arranged in the honeycomb direction of the horizontal spacer 9. The two ends of the horizontal spacer 9 respectively fit against the side walls of two of the longitudinal spacer groups 10. The top surfaces 94 of the respective horizontal spacers 9 are all at the same height as the top surface 412 of the circumferential border 41. By arranging the horizontal spacer 9 made of honeycomb paper on the side surface of the corner guard frame 4 and pasting it on the circumferential border 41 inside the corner guard frame 4, the strong flat pressure of the honeycomb paperboard 5 is fully utilized to enhance the anti-clamping ability.

[0068] The number of the longitudinal spacer groups 10 is four groups. The four groups of longitudinal spacer groups 10 are respectively located at the four corners of the corner guard frame 4. The bottom walls of the longitudinal spacer groups 10 fit against the honeycomb paperboard 5. The top surfaces of the respective longitudinal spacer groups 10 are all at the same height as the top surface 412 of the circumferential border 41. The longitudinal spacer groups 10 are arranged at the ends of the limit backing plate 8 in the width direction of the honeycomb paperboard 5. The two side walls of the longitudinal spacer groups 10 in the width direction of the honeycomb paperboard 5 respectively fit against the limit backing plate 8 and the side folded edge 411 of the circumferential border 41. The two end walls of the longitudinal spacer groups 10 in the length direction of the honeycomb paperboard 5 respectively fit against the support paper tube 7 near the longitudinal spacer and the side folded edge 411 of the circumferential border 41.

[0069] The top surfaces of the horizontal spacer 9 and the longitudinal spacer groups 10 are all at the same height as the top surface 412 of the circumferential border 41. The high strength of the corner guard frame 4 is used to wrap each honeycomb paperboard 5, ensuring that during the stacking, incoming material turnover, transportation, and packing processes, the circumferential border 41 can protect the components such as each backing plate inside the corner guard frame 4 from being damaged, and guaranteeing the reliability and aesthetic appearance of the materials.

[0070] Each longitudinal spacer group 10 includes two or more longitudinal spacers 16 that are parallel and arranged in a fitting manner along the width direction of the honeycomb paperboard 5. Each longitudinal spacer 16 extends along the length direction of the honeycomb paperboard 5. The honeycomb direction of the longitudinal spacer 16 is parallel to the width direction of the honeycomb paperboard 5. Through the settings of the peripheral circumferential border 41, honeycomb paperboard 5, and each horizontal spacer 9 and longitudinal spacer 16, etc., the product is guaranteed to have strong anti-clamping force.

[0071] One of the longitudinal cushion groups 10 is provided with a drainage joint placement groove 101, and the drainage joint placement groove 101 is located at the first end in the length direction of the honeycomb paperboard 5. The longitudinal cushion group 10 includes a first longitudinal cushion 16 and a second longitudinal cushion 16. The first longitudinal cushion 16 fits against the circumferential border 41 in the width direction of the honeycomb paperboard 5. The length of the first longitudinal cushion 16 is less than that of the second longitudinal cushion 16. The drainage joint placement groove 101 is surrounded by the honeycomb paperboard 5, the end wall of the first longitudinal cushion 16, the side wall of the second longitudinal cushion 16, and the circumferential border 41.

[0072] The accessory accommodation cushion plate 13 extends along the width direction of the honeycomb paperboard 5 and is adhered to the limit cushion plate 8 near the second end of the honeycomb paperboard 5. The accessory accommodation cushion plate 13 is provided with a strapping tape placement groove 131, and the strapping tape placement groove 131 is recessed downward from the top surface of the accessory accommodation cushion plate 13.

[0073] The air conditioner outdoor unit 1 is usually equipped with accessories such as a strapping tape 14, a drainage joint 15, and a connecting pipe. The effective placement of the accessories can ensure the normal flow of the production line, avoid the loss of accessories caused by unreliable placement of the accessories or inconvenient packaging that affects the production efficiency. Based on the shape of the drainage joint 15 equipped with the air conditioner outdoor unit, the bottom packaging cushion assembly 3 is provided with a placement structure specifically for placing the drainage joint 15, overcomes the characteristic of the environmentally friendly packaging material that is not easy to process special shapes, and has a special design for the placement position of the accessories to ensure effective restraint of the accessories and avoid problems such as the drainage joint 15 and other accessories being easily dropped on the production line or during the turnover process. In addition, since accessories such as the strapping tape 14 need to be placed, it is necessary to ensure the thickness of the cushion plate provided with the accessory groove. By setting multiple thinner cushion plates laminated and adhered together, the problem that the flat compression strength decreases instead as the thickness of the honeycomb paperboard increases is solved.

[0074] The support cushion plate 12 extends along the width direction of the honeycomb paperboard 5 and is adhered to the limit cushion plate 8 near the second end of the honeycomb paperboard 5. In the length direction of the honeycomb paperboard 5, the support cushion plate 12 is located between the accessory accommodation cushion plate 13 and the support paper tube 7.

[0075] See Figure 11 , the top packaging cushion assembly 2 includes a top paper frame 21 and a cushion plate assembly 22. The top paper frame 21 includes a paper frame top wall 211 and a paper frame folding edge 212, and the paper frame folding edge 212 extends vertically downward from the outer edge of the paper frame top wall 211. The cushion plate assembly 22 is located inside the top paper frame 21 and is fixedly adhered to the paper frame folding edge 212.

[0076] The top paper frame 21 and the backing plate assembly 22 are both made of honeycomb paper. The backing plate assembly 22 includes a first longitudinal backing plate 221, a second longitudinal backing plate 222, a first transverse backing plate 223 and a second transverse backing plate 224. The first longitudinal backing plate 221 and the second longitudinal backing plate 222 are oppositely arranged along the width direction of the top paper frame 21, and the first transverse backing plate 223 and the second transverse backing plate 224 are oppositely arranged along the length direction of the top paper frame 21. The honeycomb directions of the first longitudinal backing plate 221 and the second longitudinal backing plate 222 are both parallel to the width direction of the top paper frame 21, the honeycomb direction of the first transverse backing plate 223 is parallel to the length direction of the top paper frame 21, the number of the second transverse backing plates 224 is two, and the two second transverse backing plates 224 are stacked and pasted along the vertical direction, and the honeycomb direction of each second transverse backing plate 224 is parallel to the vertical direction.

[0077] The top paper frame 21 can protect the internal backing plate assembly 22. At the same time, the backing plate assembly 22 is pasted on the paper frame hem 212 of the top paper frame 21. The flat compression strength of the honeycomb cardboard 5 is used to improve the anti-clamping ability of the product. For the relatively wide second transverse backing plate 224, it is pasted flat. At the same time, in order to ensure the strength, more than two second transverse backing plates 224 made of honeycomb paper can be used for composite pasting.

[0078] As can be seen from the above, due to its own weight, the chassis of the air conditioner outdoor unit is an uneven curved surface, and the weight is mainly supported by the two feet of the outdoor unit, resulting in concentrated stress on the packaging materials at the supporting feet. This bottom packaging cushion assembly is provided with support paper tubes at the supported parts such as the feet of the air conditioner outdoor unit, and the square paper tube structure directly supports the feet. At the same time, a reinforced honeycomb cardboard is designed and used under the square paper tube, which can play a certain buffering role, ensuring that it can not only provide strong support and still maintain sufficient support strength after a drop impact, but also has a certain buffering and protection ability, solving the problems of insufficient support and no secondary buffering ability in the prior art. At the same time, by pasting a whole piece of reinforced honeycomb cardboard on the inner side of the corner guard frame, the middle packaging backing plate, the support paper tube and other honeycomb cardboards are pasted on the whole piece of honeycomb cardboard, ensuring the integrity of the overall structure. In addition, honeycomb cardboard products are prone to be bumped and damaged during the turnover process and production packaging. The technical solution designs corner guard structures around the honeycomb cardboard to improve the overall structural strength.

[0079] In addition, the number of the support paper tubes can also be two or more, and at least one support paper tube is respectively arranged at both ends of the middle packaging backing plate in the length direction. The number of the limiting backing plates can also be two or more, and at least one limiting backing plate is respectively arranged at both ends of the honeycomb cardboard in the length direction. The number of the second transverse backing plates can also be two or more, and the second transverse backing plates are stacked and pasted along the vertical direction. The above changes can also achieve the purpose of the present utility model.

[0080] Finally, it should be emphasized that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
