Technical Field

[0001] This utility model relates to the field of packaging structure technology, and in particular to a top cushioning packaging structure for an outdoor unit. Background Technology

[0002] During transportation, air conditioner outdoor units need to be protected by packaging structures. The advantage of this is that through effective protective measures, the product is protected from damage during transportation and storage, maintaining its performance and appearance integrity.

[0003] Currently, most mainstream air conditioner outdoor units on the market are packaged using plastic bags to cover the unit for protection, with foam material used for cushioning at the top and bottom, and finally the entire package placed in an outer cardboard box. This packaging method effectively protects the outdoor unit from damage during transportation to some extent. However, the foam material used for the top and bottom of these units is typically EPS (Expanded Polystyrene) as cushioning. The widespread use of EPS has led to serious white pollution problems. As a non-degradable material, EPS is difficult to break down in the natural environment, causing a large amount of plastic waste. Furthermore, the current packaging method uses a variety of different materials, such as plastic bags, top and bottom foam, and boxes, resulting in complexity in material preparation on the production floor. This not only increases the difficulty of inventory and logistics management but also reduces the efficiency of packaging operations.

[0004] Therefore, it is necessary to design a new structure that is environmentally friendly, recyclable, low-cost, and shock-resistant, in order to solve the problems of environmental pollution and production complexity in the current packaging methods for air conditioner outdoor units.

[0034] Air conditioner outdoor units are typically protected during transportation using plastic bags, EPS foam, and paper boxes. While this traditional packaging method effectively protects the product, the widespread use of EPS foam has led to serious environmental pollution problems. In addition, the use of multiple materials increases the complexity of material preparation, resulting in low inventory management and packaging efficiency.

[0035] To address this issue, this utility model provides a top-mounted buffer packaging structure for outdoor units that is environmentally friendly, recyclable, low-cost, and offers excellent moisture-proof, corrosion-proof, and shock-resistant protection, thus solving the problems of environmental pollution and production complexity associated with current packaging methods for air conditioner outdoor units.

[0036] Specifically, by employing an inflatable air cushion body 1, combined with a hot-pressing section 104 and a hot-pressing bending line 105, an environmentally friendly, recyclable, low-cost packaging method with excellent moisture-proof, corrosion-proof, and shock-resistant protection is provided. The air cushion body 1 uses a long strip-shaped air cavity 101 connected to an inflation channel 102, forming an air column after inflation, which effectively absorbs external impact forces and achieves shock protection. Simultaneously, the film material used in the air cushion body 1 has good moisture-proof and corrosion-proof properties, protecting the outdoor unit of the air conditioner from environmental factors. The design of the hot-pressing section 104 and the bending line allows the air cushion to be folded into a square structure as needed, facilitating transportation and storage, and the materials used are recyclable, reducing environmental pollution. Furthermore, the overall structure is simple, the production process is relatively simple, production costs are reduced, and the problems of environmental pollution and production complexity in current air conditioner outdoor unit packaging methods are solved.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] Please see Figure 1 An outdoor unit top cushioning packaging structure includes an air cushion body 1, on which a hot pressing part 104 and a hot pressing bending line 105 are provided.

[0039] In this embodiment, the air cushion body 1 is the core component of the outdoor unit top cushioning packaging structure. After inflation, it provides cushioning protection to prevent external impacts from damaging the top cover of the air conditioner outdoor unit. The air cushion body 1 is designed as a flexible, inflatable structure, which provides ideal cushioning during packaging and facilitates folding and stacking during transportation and storage.

[0040] The hot-pressing section 104 provided on the air cushion body 1 is a key part of the design. The hot-pressing section 104 is typically processed using high temperature and high pressure, enabling localized fusion or reinforcement of the material to form a shaped structure. These hot-pressing sections 104 have the following functions:

[0041] By incorporating a heat-pressing section 104 on the air cushion body 1, the overall stability of the air cushion can be effectively enhanced, ensuring that it maintains a certain shape during transportation and does not undergo large-scale deformation due to external forces. The heat-pressing section 104 also helps the air cushion body 1 form fold lines, allowing the air cushion to maintain a certain degree of flexibility after inflation. By precisely controlling the position and shape of the heat-pressing section 104, designers can ensure that the air cushion can fold along a predetermined path when needed, thereby saving space during packaging and transportation.

[0042] The function of the hot-pressed bending lines 105 is similar to that of the hot-pressed section 104, mainly used to help form the folded parts of the air cushion body 1. These bending lines are usually designed as fold lines perpendicular to the air column of the air cushion body 1, for the following purpose:

[0043] The hot-pressing bending line 105, by setting predetermined folding positions, can effectively guide the air cushion body 1 to automatically form the required folding shape during inflation, thereby creating a five-sided structure that surrounds the top cover of the air conditioner. The bending line design allows the air cushion body 1 to tightly wrap around the top of the outdoor unit, providing more balanced cushioning protection. Because the bending line is pre-positioned on the air column body, it ensures the correct bending direction of the air column after inflation, avoiding uneven expansion in certain areas.

[0044] The bend lines also make the packaging structure easier to install and disassemble. These bend lines give the packaging structure a self-positioning function; users only need to place the air cushion body 1 correctly to ensure it adheres stably to the top of the air conditioner, avoiding cumbersome fixing steps during installation.

[0045] In summary, the hot-pressing section 104 and the hot-pressing bending line 105 play a crucial role in the air cushion body 1. They not only control the structural stability of the air cushion and ensure the uniform expansion of the air column, but also help the packaging structure quickly form a suitable enclosure shape for the outer cover after inflation, thus providing effective protection. Through a reasonable design of the hot-pressing section 104 and the bending line, efficient and convenient installation and disassembly processes can be achieved while ensuring packaging effectiveness, thereby improving the transportation and storage efficiency of the packaging.

[0046] In one embodiment, please refer to Figures 1 to 2 The air cushion body 1 has several elongated air chambers 101, which are distributed on the surface of the air cushion body 1.

[0047] In this embodiment, the air cushion body 1 is designed to provide efficient cushioning protection for the outdoor unit of the air conditioner. Specifically, the air cushion body 1 has several elongated air chambers 101, which are evenly distributed on the surface of the air cushion body 1. This design not only helps to evenly distribute external forces and improve the overall cushioning effect, but also allows for adaptation to outdoor units of different sizes and shapes by adjusting the number and arrangement of the air chambers.

[0048] In one embodiment, please refer to Figure 1 The air cushion body 1 is provided with an inflation channel 102, and several elongated air chambers 101 are connected to the inflation channel 102.

[0049] In this embodiment, the inflation channel 102 is one of the key components of the entire air cushion body 1. It ensures that the gas can be evenly distributed into each air chamber, thereby guaranteeing good stability and uniformity of the air cushion body 1 after inflation. In practical applications, operators only need to connect the inflation device to one end of the inflation channel 102 to quickly complete the inflation process of the air cushion body 1.

[0050] In one embodiment, please refer to Figures 1 to 2 A one-way inflation valve 103 is provided at the connection between the elongated air cavity 101 and the inflation channel 102. When gas enters the inflation channel 102, it enters the elongated air cavity 101 through the one-way inflation valve 103. The elongated air cavity 101 bulges outward from the air cushion body 1 to form an air column.

[0051] Of particular note is the one-way inflation valve 103 installed at the connection between the elongated air chamber 101 and the inflation channel 102. When gas enters the inflation channel 102 and passes through the one-way inflation valve 103, it is effectively guided into the interior of each elongated air chamber 101. The one-way inflation valve 103 is designed to prevent gas backflow and ensure that gas does not easily leak out once it enters the air chamber. Furthermore, since each air chamber bulges outward from the air cushion body 1, this not only increases the overall thickness of the air cushion but also significantly improves its ability to absorb external impacts, thus providing more effective protection for the outdoor unit of the air conditioner.

[0052] In other embodiments, considering different application scenarios and needs, the elongated air cavity 101 expands simultaneously to both the inner and outer sides of the air cushion body 1 during inflation, forming a cylindrical air column structure. This design allows the air cushion to adjust its shape as needed to better conform to the contours of the outdoor air conditioning unit, providing more precise protection. Furthermore, this double-sided expansion method further enhances the air cushion's pressure resistance, enabling it to maintain good morphological stability even under significant external pressure.

[0053] In one embodiment, please refer to Figure 1 The aforementioned inflation channel 102 is located at one end of the air cushion body 1, and the inflation channel 102 is perpendicular to the elongated air cavity 101.

[0054] In this embodiment, regarding the design of the air cushion body 1, the inflation channel 102 is cleverly positioned at one end of the air cushion body 1 and is perpendicular to the elongated air cavity 101. This design not only simplifies the inflation process but also ensures that the gas can be evenly distributed into each air cavity, thereby guaranteeing a consistent and stable inflation effect for the entire air cushion body 1.

[0055] In one embodiment, please refer to Figure 1The aforementioned hot-pressing bending lines 105 are two first discontinuous easy-bend lines perpendicular to the elongated air cavities 101. Each first discontinuous easy-bend line includes several first hot-pressing points 1051, which are respectively located on several elongated air cavities 101 without blocking them. This design allows operators to easily complete the folding action along these pre-set easy-bend lines when the air cushion needs to be folded, while maintaining unaffected gas flow within each air cavity, thus ensuring the stability of the air cushion bag's shape and its cushioning performance after folding.

[0056] In one embodiment, please refer to Figure 1 The aforementioned air cushion body 1 has heat-pressing portions 104 at its corners. Specifically, each of the four corners of the air cushion body 1 has a heat-pressing portion 104, which is composed of several parallel, discontinuous, easily foldable lines. This design not only enhances the structural strength at the corners of the air cushion and improves durability, but also provides predetermined folding points, facilitating the shaping of the air cushion and adapting to different packaging needs. Simultaneously, it ensures unaffected gas flow, optimizes space utilization efficiency, and improves user experience and ease of operation. This design cleverly combines functionality and economy, significantly improving the overall performance of the product.

[0057] In one embodiment, please refer to Figure 1 The aforementioned hot-pressing section 104 consists of several second discontinuous foldable lines perpendicular to the elongated air cavities 101. Each second discontinuous foldable line includes several second hot-pressing points 1041, which are respectively located on the elongated air cavities 101 without blocking them. This method not only enhances the structural strength of the corner area of ​​the air cushion body 1, but also allows the air cushion to be more easily folded or bent into specific shapes when necessary, adapting to air conditioner outdoor unit top covers of different sizes and shapes.

[0058] Therefore, the design of the inflation channel 102 being vertically connected to the air chamber simplifies the inflation process; while the presence of the first and second discontinuous folding lines ensures smooth gas flow within the air chamber and provides flexible folding options, enhancing the application range and practicality of the packaging structure. These innovative designs work together to provide a more efficient, environmentally friendly, and economical packaging solution for air conditioner outdoor units.

[0059] In one embodiment, please refer to Figures 2 to 7The aforementioned air cushion body 1 is folded along the heat-pressing section 104 and the heat-pressing bending line 105 to form a square structure with an opening at the lower end. After the air column is inflated, the operator can fold it according to the preset heat-pressing section 104 and the two bending lines. These pre-set lines ensure that the air cushion bag can accurately surround the air conditioner outdoor unit to form a five-sided enclosure structure (front, back, left, right, and top). This design not only ensures that the packaging structure tightly wraps the air conditioner outdoor unit, but also effectively avoids the risk of displacement of the air cushion body 1 during use.

[0060] In one embodiment, please refer to Figure 3 and Figure 4 Double-sided adhesive 106 is provided on the inner wall of the air cushion body 1. These double-sided adhesive 106 are carefully positioned on the front, back, left, and right sides of the air cushion bag to ensure that the four sides are firmly bonded and fixed to the air conditioner unit after the air cushion body 1 is placed on the top cover of the air conditioner unit. This not only prevents the air cushion body 1 from slipping or falling off during the handling or transportation of the air conditioner unit, but also simplifies subsequent packaging steps on the production line and improves work efficiency.

[0061] In one embodiment, please refer to Figures 1 to 7 The aforementioned outdoor unit top cushioning packaging structure also includes a protective film 107, which is located below the air cushion body 1.

[0062] In this embodiment, the protective film 107 is preferably made of a polymer material with excellent wear resistance and tear resistance, such as polyethylene (PE) or polypropylene (PP). These materials have good flexibility and mechanical strength, and are low in cost and easy to process and mold. The protective film 107 is designed to be located below the air cushion body 1, that is, in direct contact with the top cover and body of the outdoor unit of the air conditioner. Its main function is to prevent the surface of the outdoor unit of the air conditioner from being scratched and worn during transportation and handling.

[0063] The size of the protective film 107 is customized according to the specific specifications of the air conditioner outdoor unit to ensure complete coverage of the areas requiring protection, including but not limited to the top cover, sides, and bottom sections. To accommodate different models of air conditioner outdoor units, the protective film 107 can be designed to be adjustable in size, for example, by leaving pre-cut lines or by using elastic materials.

[0064] Special coatings or additives can be added to the protective film 107 to give it a certain degree of moisture and corrosion resistance, making it particularly suitable for storage and transportation in high-humidity or corrosive environments. For high-end air conditioner outdoor units with many sensitive electronic components, antistatic components can be added to the protective film 107 to prevent static electricity buildup from damaging the internal circuitry. The protective film 107 can also be printed with relevant product information, warning signs, or brand logos to improve product visibility and remind operators to handle and move it correctly.

[0065] In another embodiment, please refer to Figure 9 The top cushioning packaging structure of the outdoor unit also includes an elastic band 108, which fixes the air cushion body 1 to the outdoor unit.

[0066] When applying the above packaging structure to the outdoor unit of an air conditioner, firstly, the protective film 107 is laid on top of the outdoor unit. Then, the air cushion body 1 is inflated and folded to form a square structure that surrounds five sides. Finally, the air cushion body 1 is fixed to the outdoor unit using double-sided tape 106 or elastic band 108, ensuring that the entire packaging structure fits tightly and remains stable.

[0067] This design cleverly combines the functions of traditional top foam and packaging bags into a single material, achieving the environmental goal of reducing EPS usage while lowering logistics costs and improving packaging efficiency. When uninflated, the air cushion bag is flat, small in size and lightweight, facilitating storage and transportation; on-site inflation allows for rapid packaging, significantly improving production efficiency. Made from environmentally friendly and recyclable materials, it reduces the use of non-degradable materials such as EPS foam, aligning with the modern trend of green packaging.

[0068] In one embodiment, the aforementioned elongated air cavities are regularly arranged on the surface of the air cushion body 1. Rectangular hot-pressing portions 104 are provided at the four corners of the air cushion body 1, and two bends are provided adjacent to the hot-pressing portions 104. These hot-pressing portions 104 and bends are achieved through hot-pressing points on the elongated air cavities. The hot-pressing points are evenly distributed and do not affect gas flow, while reducing the amount of air in the inflation part, making this part soft and easy to fold. After inflation, the air cushion body 1 is folded to form a square structure including five sides: front, back, left, right, and top, with one side open for fitting over the top cover of the outdoor unit of the air conditioner, thus providing all-round protection for the top cover. At the same time, the protective film 107 provides abrasion protection around the outdoor unit body. Double-sided adhesive 106 is installed on the four sides of the air cushion body 1. After inflation, the air cushion body 1, formed by folding, can be fixed to the outdoor unit to prevent displacement and ensure stability during transportation. When deflated, the air cushion body 1 is a flat rectangle; when inflated, it forms a square structure with one open side. The deflated state facilitates transportation and reduces space occupation.

[0069] In one embodiment, the air cushion body 1 is a single layer of adhesive film, and the elongated air cavity 101 is another layer of adhesive film. Of course, the inflatable portion of this embodiment may include at least two layers of adhesive film, i.e., more than one elongated air cavity 101, to provide cushioning protection. The left end of each elongated air cavity 101 is heat-sealed between two layers of adhesive film to form a one-way inflation valve 103103. The one-way inflation valve 103103 ensures that air can only enter the air column through the inflation channel 102 without leakage. One end of the inflation channel 102 is open, and the other end is closed. During use, the open end is connected to an inflation device for inflation.

[0070] The hot-pressing section 104 consists of several second hot-pressing points 1041, which are spaced apart, evenly distributed, and centered along the width of each elongated air cavity 101. Although the hot-pressing points do not obstruct the flow of gas inside the air column, they effectively reduce the amount of air required for the hot-pressing section 104, making the area more flexible and foldable. The area of ​​the second hot-pressing points 1041 accounts for approximately 70% of the area of ​​the hot-pressing section 104. Hot-pressing bending lines 105 are provided on the left and right sides adjacent to the hot-pressing section 104, consisting of two rows of parallel first hot-pressing points 1051, and their function is the same as that of the second hot-pressing points 1041. The presence of the hot-pressing bending lines 105 allows the air column to bend downwards through this part after inflation, thereby forming the left and right side structures of the air cushion bag.

[0071] In general, after being inflated and folded using an inflation device, the air cushion body 1 can form as follows: Figure 2 The structure shown has an opening on one side and is surrounded on five sides. Double-sided adhesive tape 106 is provided on the front, back, left, and right sides of the inflatable part. Its function is to allow the air column pad bag to be placed on the top cover of the outdoor unit, and the four sides can be glued and fixed to the machine body, which facilitates the subsequent packaging operations on the production line.

[0072] like Figure 8 As shown, an outdoor unit top cushioning packaging structure is formed by heat-sealing two layers of plastic film. The outer plastic film is a protective film 107, the size of which is just enough to cover the outdoor unit body. The inflation channel 102 can be designed to be open at both ends, allowing inflation to be performed simultaneously from both ends by two inflation devices, thereby improving inflation efficiency. In addition, the protective film 107 can be shared with the elongated air chamber 101, or a separate plastic film can be used to bond to the elongated air chamber 101.

[0073] After inflation and molding, the double-sided adhesive 106 on the inside of the air cushion body 1 can be replaced with an elastic band 108. This method can also be used to fix the air column cushion bag on the outdoor unit and prevent it from sliding.

[0074] In summary, the air cushion body 1 replaces traditional EPS foam, reducing environmental pollution and using environmentally friendly materials, thus contributing to improved green biodegradability of air conditioner packaging. By combining the functions of the outdoor unit's top foam and packaging bag into one material, the types and quantities of packaging materials can be reduced. When uninflated, the air cushion body 1 is flat, effectively reducing the volume of incoming materials, significantly lowering transportation costs, and increasing the batch size per shipment.

[0075] This top-mounted cushioning packaging structure for outdoor units not only solves the problems existing in traditional air conditioner outdoor unit packaging, but also provides a more efficient, economical and environmentally friendly solution through innovative design.

[0076] The above-mentioned outdoor unit top cushioning packaging structure, by using a recyclable air cushion body 1, combined with a hot pressing part 104 and a hot pressing bending line 105, not only simplifies the production process and reduces costs, but also ensures the environmental friendliness of the packaging materials; the air cushion body 1 has good shock resistance characteristics, which can effectively protect the outdoor unit of the air conditioner, and is flat when not inflated, avoiding the environmental pollution problems of traditional packaging methods and reducing the complexity of production.

[0077] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
