Description

Technical Field

[0001] This utility model relates to the field of inflatable products, and in particular to an air chamber connecting component and an inflatable product. Background Technology

[0002] Inflatable products are disposable or reusable products that achieve a specific purpose through inflation, such as swimming pools, hovercrafts, and air cushions. They are typically made of multiple layers of plastic or rubber materials and are inflated to achieve the desired shape and size.

[0003] Most inflatable products on the market, if they require different air chambers, are usually made by directly splicing fabric together to form a single piece. Multiple air chambers cannot be connected, and each air chamber needs to have its own inflation port designed. This requires high production equipment and manpower, has low production efficiency, and cannot be modularized.

[0004] In addition, the after-sales service cost of the one-piece design is high. If a part (such as one of the air chambers) is damaged and cannot be repaired, the entire inflatable product will be scrapped, resulting in a large waste, which is not in line with the concept of environmental protection and further increases the production cost of inflatable products.

[0005] In existing technologies, when inflatable products are being inflated or deflated, the walls of the product tend to stick to the inflation / deflation ports connecting the two chambers, preventing inflation and deflation and affecting efficiency. Furthermore, if the inflation / deflation ports are stuck to the product walls during deflation, the product will not deflate sufficiently. Using a vacuum pump to expel the gas would be cumbersome and increase the cost of additional pumps. Moreover, if the product walls remain stuck to the end of the inflation / deflation port between the two chambers for an extended period, the vacuum pump may run dry, eventually damaging it. Utility Model Content

[0006] The purpose of this invention is to solve the technical problem of low inflation / deflation efficiency in the prior art. This invention provides an air chamber connecting component, which can avoid the problem of the wall of the inflated product sticking to the end of the connecting part between the two air chambers during inflation / deflation, ensuring that the inflation / deflation process of the air chambers is always unobstructed, thereby improving inflation / deflation efficiency.

[0007] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a gas chamber communication assembly, comprising:

[0008] The first connecting part includes:

[0009] the first through hole; and

[0010] A first wall defines the first through hole and includes:

[0011] First end;

[0012] The second end is positioned opposite to the first end; and

[0013] The first intermediate portion is located between the first end and the second end;

[0014] The second connecting part includes:

[0015] the second through hole; and

[0016] A second wall defines the second through hole, and the first wall is at least partially located within the second through hole and is sealingly connected to the second wall, the second wall comprising:

[0017] The third end;

[0018] The fourth end is disposed opposite to the third end; and

[0019] The second intermediate portion is located between the third end and the fourth end;

[0020] A ventilation section is provided on the first wall and / or the second wall.

[0021] Using the above technical solution, the air chamber communication assembly provided in this application is disposed between at least two air chambers. The first wall of the first connecting part extends at least partially into the second through hole of the second connecting part and is sealed to the second wall, thereby achieving the cooperation between the first and second connecting parts and forming airflow communication between the at least two air chambers. Therefore, the user only needs to use the inflation / deflation valve provided on one of the air chambers to complete the inflation / deflation of at least two air chambers, which is simple to operate and highly efficient. During the inflation / deflation process, if the wall of an air chamber adheres to the end of the first wall of the first connecting part and / or the end of the second wall of the second connecting part, thereby blocking the first through hole and preventing gas flow between the at least two air chambers, the presence of at least one ventilation part on the first and / or second wall effectively prevents the wall of the air chamber from adhering to the end. Even if the end is adhered to the wall of the air chamber, gas can still communicate between the at least two air chambers through the ventilation part, thus avoiding the problem caused by the air chamber wall adhering during inflation / deflation and ensuring that the inflation / deflation process is always unobstructed, thereby improving inflation / deflation efficiency.

[0022] According to a specific embodiment of the present invention, the ventilation section includes a plurality of protrusions, which are spaced apart.

[0023] Using the above technical solution, the ventilation section includes multiple spaced protrusions, and gas can flow between at least two air chambers through the recess formed between two adjacent protrusions, ensuring that the inflation and deflation process of the air chambers is always unobstructed, thereby improving inflation and deflation efficiency.

[0024] According to a specific embodiment of the present invention, the plurality of protrusions are spaced apart at the first end of the first wall.

[0025] According to a specific embodiment of the present invention, the plurality of protrusions are spaced apart at the second end of the first wall.

[0026] According to a specific embodiment of the present invention, the plurality of protrusions are spaced apart at the first end and the second end of the first wall.

[0027] According to a specific embodiment of the present invention, the plurality of protrusions are spaced apart at the third end of the second wall.

[0028] According to a specific embodiment of the present invention, the plurality of protrusions are spaced apart at the first end of the first wall and the third end of the second wall.

[0029] According to a specific embodiment of the present invention, the plurality of protrusions are spaced apart at the second end of the first wall and the third end of the second wall.

[0030] According to a specific embodiment of the present invention, the plurality of protrusions are spaced apart at the first end, the second end, and the third end of the first wall.

[0031] According to another specific embodiment of the present invention, the venting part includes an annular body, the annular body including at least one first through hole.

[0032] By adopting the above technical solution, gas can flow between at least two gas chambers through the first through hole of the annular body, ensuring that the gas filling and emptying process of the gas chambers is always unobstructed, thereby improving the gas filling and emptying efficiency.

[0033] According to another specific embodiment of the present invention, the annular body protrudes from the first end of the first wall.

[0034] According to another specific embodiment of the present invention, the annular body protrudes from the second end of the first wall.

[0035] According to another specific embodiment of the present invention, the annular body protrudes from the first end and the second end of the first wall.

[0036] According to another specific embodiment of the present invention, the annular main body protrudes from the third end of the second wall.

[0037] According to another specific embodiment of the present invention, the annular body protrudes from the first end of the first wall and the third end of the second wall.

[0038] According to another specific embodiment of the present invention, the annular body protrudes from the second end of the first wall and the third end of the second wall.

[0039] According to another specific embodiment of the present invention, the annular body protrudes from the first end, the second end, and the third end of the first wall.

[0040] According to another specific embodiment of the present invention, the ventilation part further includes a plurality of protrusions; the plurality of protrusions are spaced apart at at least one of the first end, the second end and the third end; the annular body is provided at least one of the first end, the second end and the third end where the plurality of protrusions are not provided.

[0041] According to another specific embodiment of the present invention, the ventilation section includes:

[0042] A second through hole is provided in the first middle portion of the first wall; and

[0043] The third through hole is located in the second middle portion of the second wall and is aligned with the second through hole.

[0044] According to another specific embodiment of the present invention, the ventilation part further includes an annular body having at least one first through hole, the annular body being disposed at at least one of the first end, the second end and the third end of the first wall.

[0045] According to another specific embodiment of the present invention, the ventilation part further includes a plurality of protrusions, which are spaced apart at at least one of the first end, the second end and the third end of the first wall.

[0046] According to another specific embodiment of the present invention, the ventilation section includes:

[0047] A first airflow channel, the first airflow channel being disposed within the first middle portion of the first wall and including a first opening and a second opening; and

[0048] The second airflow channel is disposed on the second middle portion of the second wall and aligned with the second opening of the first airflow channel.

[0049] By adopting the above technical solution, without the need for additional annular body or protrusion, gas can be sequentially passed through the second through hole and the third through hole to achieve airflow communication between at least two gas chambers, ensuring that the gas filling and emptying process of the gas chambers is always unobstructed, thereby improving the filling and emptying efficiency.

[0050] According to another specific embodiment of the present invention, the first wall is at least partially located within the second through hole of the second wall and a sealing structure is provided between the first wall and the second wall.

[0051] According to another specific embodiment of the present invention, the second end of the first wall includes a snap-fit ​​protrusion, and the third end of the second wall includes a snap-fit ​​recess. The snap-fit ​​protrusion snaps into the snap-fit ​​recess to fix the first connecting part to the second connecting part.

[0052] Using the above technical solution, the snap-fit ​​protrusion can abut against the snap-fit ​​recess. Through the interlocking of the snap-fit ​​protrusion and the snap-fit ​​recess, the first connecting part and the second connecting part are snapped together, further ensuring that the two air chambers are not easy to fall off during use. Moreover, the two air chambers can rotate relative to each other under the action of external force, which can provide flexibility for inflatable products and improve the user experience.

[0053] According to another specific embodiment of the present invention, the sealing structure includes a rib, which is integrally disposed on the outer surface of the first wall and abuts against the inner surface of the second wall, or the rib is integrally disposed on the inner surface of the second wall and abuts against the outer surface of the first wall.

[0054] By adopting the above technical solution, a rib is provided between the first wall and the second wall, and there is no need to open a sealing groove. This can improve the airtightness between the first connection part and the second connection part, reduce the processing difficulty, and improve production efficiency.

[0055] According to another specific embodiment of the present invention, the sealing structure includes at least one sealing ring, and at least one sealing groove is provided on the outer surface of the first wall or the inner surface of the second wall. The at least one sealing ring is disposed in the at least one sealing groove to form a seal between the outer surface of the first wall and the inner surface of the second wall.

[0056] By adopting the above technical solution, a sealing ring is set between the first wall and the second wall, which can further improve the airtightness between the first connecting part and the second connecting part, and ensure that the inflatable product will not leak air.

[0057] According to another specific embodiment of the present invention, the height h1 between the first end and the second end of the first wall is greater than or equal to the height h2 between the third end and the fourth end of the second wall.

[0058] According to another specific embodiment of the present invention, an air chamber communication component is disclosed, wherein the height of the snap-fit ​​protrusion is less than or equal to the height of the snap-fit ​​recess.

[0059] Using the above technical solution, when the first connecting part is pressed to connect with the second connecting part, since the height of the snap-fit ​​protrusion is less than or equal to the height of the snap-fit ​​recess, the first wall does not protrude from the second through hole, thus avoiding damage to the fabric of the first inflation chamber from the first wall protruding.

[0060] According to another specific embodiment of the present invention, at least one of the second end of the first wall and the fourth end of the second wall includes a chamfered surface so as to facilitate the insertion of the first wall of the first connecting portion into the second through hole.

[0061] Using the above technical solution, when the first connecting part is inserted into the second connecting part, the beveled surface at the chamfer can provide guiding force, making it easy to achieve rapid assembly by pressing with external force.

[0062] This utility model also discloses an inflatable product, comprising:

[0063] A first gas filling chamber includes a first gas filling outer wall, the first gas filling outer wall defining a first gas filling chamber;

[0064] The second gas filling includes a second gas filling outer wall, the second gas filling outer wall defining a second gas filling chamber; and

[0065] In any of the above embodiments, the first end of the first wall includes a first extension section connected to the first gas-filled outer wall, and the first connecting portion protrudes outside the first gas-filled chamber; the fourth end of the second wall includes a second extension section connected to the second gas-filled outer wall, and the second connecting portion extends toward the interior of the second gas-filled chamber.

[0066] By adopting the above technical solution, by setting a first connecting part that is fluidly connected to the air chamber (e.g., the second inflation chamber) of the inflatable product, and a second connecting part that is fluidly connected to another air chamber (e.g., the first inflation chamber) of the inflatable product, or by setting a first connecting part that is fluidly connected to the first inflation chamber and a second connecting part that is fluidly connected to the second inflation chamber, the larger complete body of the inflatable product can be divided into different parts for design and production, realizing modular production of the inflatable product. For example, the first connecting part and the second inflation chamber can be one module, and the first inflation chamber and the second connecting part can be another module. Even if any module is damaged, only the corresponding module needs to be replaced. In addition, for after-sales service of inflatable products, modular design can also realize modular after-sales service, which can reduce the probability of scrapping the entire product and has great benefits in terms of environmental protection and production cost control.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0147] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0148] See Figure 1 , Figure 1 This illustration shows a schematic diagram of the car mattress and seat assembly provided in an embodiment of this application. This embodiment exemplarily provides a car mattress 10 for fitting a seat 20. The car mattress 10 includes a concave-convex structure 121, and the seat 20 includes a concave-convex portion 21. The concave-convex portion 21 engages with the concave-convex structure 121, meaning the concave-convex structure 121 of the car mattress 10 can flatten the concave-convex portion 21 of the seat 20, thereby making the car mattress 10 more stable during use.

[0149] Exemplarily, seat 20 includes a first seat cushion 201, a first backrest 202, a second seat cushion 203, and a second backrest 204, wherein the first seat cushion 201 and the first backrest 202 are connected, and the second seat cushion 203 and the second backrest 204 are connected. Exemplarily, the first seat cushion 201 is a front seat cushion (e.g., a first-row seat cushion), and the second seat cushion 203 is a rear seat cushion (e.g., a second-row seat cushion). It is understood that the embodiments of this application do not limit the first seat cushion 201 and the second seat cushion 203. For example, the first seat cushion 201 can also be a second-row seat cushion, and correspondingly, the second seat cushion 203 can be a third-row seat cushion. By analogy, for mid-size and large SUVs and other models, the first seat cushion 201 can also be a third-row seat, etc.

[0150] For example, see Figure 1 After the first backrest 202 is laid flat, there are adjacent first recesses 211 and first protrusions 212 near the connection between the first seat cushion 201 and the first backrest 202. The first recess 211 is in concave-convex fit with the first protrusion 1211 of the concave-convex structure 121, and the first protrusion 212 is in concave-convex fit with the first recess 1214 of the concave-convex structure 121. The first backrest 202 has a second recess 213 adjacent to the first protrusion 212, and the second recess 213 is in concave-convex fit with the second protrusion 1212 of the concave-convex structure 121.

[0151] A third recess 214 is provided at the connection between the second seat cushion 203 and the second backrest 204. The third recess 214 engages with the third protrusion 1213 of the concave-convex structure 121. The adjacent portions of the second seat cushion 203 and the first backrest 202 form a second protrusion 215, which engages with the second recess 1215 of the concave-convex structure 121. When the first backrest 202 is flat, the car mattress 10 is placed on the first seat cushion 201, the first backrest 202, and the second seat cushion 203. The concave-convex structure 121 of the car mattress 10 can fill the recesses at the first recess 211, the second recess 213, and the third recess 214. The aforementioned first recess 211, first convex portion 212, second recess 213, second convex portion 215, and third recess 214 together form the concave-convex portion 21 of the seat 20. The distribution and degree of concavity and convexity of the concave-convex portion 21 are determined according to the design of the seat 20, and this application does not limit it.

[0152] In some embodiments, see Figure 2 and combined Figure 1 , Figure 2 An exploded view of a car mattress provided in an embodiment of this application is shown. The car mattress 10 provided in this embodiment includes a first inflation gas 11 and a second inflation gas 12. Along a first direction X, the first inflation gas 11 is disposed above the second inflation gas 12. The second inflation gas 12 includes the aforementioned concave-convex structure 121, which is disposed on the side of the second inflation gas 12 facing away from the first inflation gas 11, and is used to match the concave-convex portion 21 of the vehicle seat. The concave-convex structure 121 and the concave-convex portion 21 are in concave-convex fit.

[0153] Using the above technical solution, the second inflation 12 includes a concave-convex structure 121, which contacts the concave-convex portion 21 of the vehicle seat and engages with the concave-convex portion 21, thereby giving the mattress good stability during use and preventing it from shaking. It also keeps the surface of the first inflation 11 flat, improving the user experience.

[0154] In some embodiments, see Figure 2 and combined Figure 1The first inflation gas 11 includes a first base sheet 1101, a first top sheet 1102, and a sponge filling portion 1103. Along the first direction X, the sponge filling portion 1103 is disposed between the first base sheet 1101 and the first top sheet 1102. The first base sheet 1101 contacts the second top sheet 1202 (described later for the second inflation gas). The first base sheet 1101 and the first top sheet 1102 together form the first inflation outer wall of the first inflation gas 11 and together enclose a first inflation chamber 111. The sponge filling portion 1103 fills the first inflation chamber 111. For example, as shown... Figure 4 As shown, when the first inflation gas 11 does not include the sponge filling part 1103, the first inflation gas 11 also includes the first side piece 1104. Along the first direction X, the first bottom piece 1101 and the first top piece 1102 are spaced apart and arranged opposite to each other. The first side piece 1104 is connected to the first bottom piece 1101 and the first top piece 1102. At this time, the first bottom piece 1101, the first top piece 1102 and the first side piece 1104 together form the first inflation gas outer wall of the first inflation gas 11 and together enclose the first inflation chamber 111.

[0155] In some embodiments, see Figure 4 and combined Figure 1 , Figure 2 , Figure 4 This diagram illustrates a specific embodiment of the air chamber communication assembly provided in this application in a first state. The second inflation gas 12 includes a second bottom plate 1201, a second top plate 1202, and a second side plate 1203. Along the first direction X, the second bottom plate 1201 and the second top plate 1202 are spaced apart and arranged opposite to each other. The second side plate 1203 is connected to the second bottom plate 1201 and the second top plate 1202. The second bottom plate 1201, the second top plate 1202, and the second side plate 1203 together form the second inflation gas outer wall of the second inflation gas 12 and together enclose the second inflation chamber 122. The concave-convex structure 121 is provided on the second bottom plate 1201, that is, the second bottom plate 1201 contacts the concave-convex portion 21 of the seat 20. Along the first direction X, the first inflation gas 11 is provided on the side of the second top plate 1202 facing away from the second bottom plate 1201. For example, the second side piece 1203 can be formed by connecting one piece of material end to end, or it can be formed by welding four pieces of material end to end. This application does not set any limit on this.

[0156] Exemplarily, the first inflation gas 11 and the second inflation gas 12 may or may not be connected. The first inflation gas 11 is filled with a sponge filling portion 1103, and the second bottom plate 1201 of the second inflation gas 12 contacts the seat 20. The second inflation gas 12 provides a flat placement platform for the first inflation gas 11, allowing the user to lie flat on the first inflation gas 11. It is understood that the first inflation gas 11 may not include the sponge filling portion 1103, or may be filled with a portion of the sponge filling portion 1103, etc., and this application embodiment does not set this limitation.

[0157] In some embodiments, see Figure 3 and combined Figure 1 , Figure 2 , Figure 3 A perspective view of a car mattress provided in an embodiment of this application is shown. The first inflation valve 11 includes an air nozzle 112, which is located at the chamfer of the first bottom sheet 1101 and the first top sheet 1102. The air nozzle 112 is used to inflate or deflate the first inflation valve 11. When the first inflation valve 11 and the second inflation valve 12 are connected, the second inflation valve 12 is also inflated or deflated through the air nozzle 112. Due to the limited space inside the car, the car mattress 10 is surrounded by obstacles, making it difficult to access the air nozzle 112. The air nozzle 112 provided in this embodiment is located at the chamfer of the first bottom sheet 1101 and the first top sheet 1102. Because a small space is left at the chamfer, it is sufficient for the user to access the air nozzle 112, thus facilitating inflation or deflation.

[0158] In the description of this application, after the pressure of the gas (e.g., air) in the second inflation chamber 122 and the first inflation chamber 111 reaches the required value, the car mattress 10 is inflated and maintains a preset shape; while when the gas in the second inflation chamber 122 and the first inflation chamber 111 is discharged, the car mattress 10 is deflated, and the volume of the car mattress 10 is greatly reduced compared to when it is inflated, thereby facilitating the storage of the car mattress 10.

[0159] In some embodiments, the thickness of the sponge filling portion 1103 along the first direction X can be 2cm to 10cm (e.g., 2cm, 3cm, 4cm, 5.5cm, 10cm) or 4cm to 7cm (e.g., 4cm, 4.6cm, 5.5cm, 7cm). Correspondingly, the width along the third direction Z is 45cm to 65cm (e.g., 45cm, 49cm, 50cm, 65cm) or 50cm. The length ranges from m to 60cm (e.g., 50cm, 53cm, 58.6cm, 60cm), and the length along the second direction Y ranges from 1.65m to 2m (e.g., 1.65m, 1.68m, 1.71m, 1.82m, 1.9m, 2m) or from 1.7m to 1.9m (e.g., 1.7m, 1.71m, 1.72m, 1.73m, 1.74m, 1.75m, 1.83m, 1.85m, 1.9m). It is understood that the dimensions of the sponge filling portion 1103 are not limited in this embodiment. For example, the dimensions of the sponge filling portion 1103 may be 6.5cm thick, 59cm wide, and 1.75m long, or 6.5cm thick, 59cm wide, and 1.8m long.

[0160] Figures 4 to 13 This application illustrates an air chamber communication component 13, used in inflatable products (such as the car mattress provided in the aforementioned embodiment). The second inflation chamber 122 and the first inflation chamber 111 are fluidly connected through the air chamber communication component 13. It is understood that the air chamber communication component 13 provided in this application is not limited to use in car mattresses, but can be used between any two inflatable gases. That is, the inflatable products provided in this application include, but are not limited to, car mattresses. For example, the air chamber communication component 13 can be used in inflatable sofas, inflatable tents, inflatable pools, inflatable spas, inflatable boats, inflatable toys, inflatable mattresses, camping mattresses, inflatable headrests, and other inflatable products. This application does not impose any limitations on this.

[0161] In some embodiments, see Figure 4 , Figure 4 This diagram illustrates a specific embodiment of the air chamber communication assembly provided in this application in a first state. The car mattress 10 also includes an air chamber communication assembly 13, which includes a first connecting portion 131 and a second connecting portion 132. The first connecting portion 131 is disposed in the second inflation chamber 122, and the second connecting portion 132 is disposed in the first inflation chamber 111. It is understood that the air chamber communication assembly provided in this application is not limited to being disposed in two air chambers, but may also be disposed in three, four, five, or other numbers of air chambers.

[0162] It is understood that the embodiments of this application do not limit the positions of the first connecting part 131 and the second connecting part 132. For example, the first connecting part 131 may also be provided in the first inflation chamber 111, and the second connecting part 132 may be provided in the second inflation chamber 122. Exemplarily, the first connecting part 131 is provided in the first bottom sheet 1101, and the second connecting part 132 is provided in the second top sheet 1202, or the first connecting part 131 is provided in the second top sheet 1202, and the second connecting part 132 is provided in the first bottom sheet 1101.

[0163] For ease of understanding, the following description will take the example of the first connecting part 131 being located in the second inflation chamber 122 and the second connecting part 132 being located in the first inflation chamber 111. The first connecting part 131 can be connected to the outer wall of the second inflation chamber 122 by means including but not limited to high-frequency welding, hot-pressing connection, etc., and the second connecting part 132 can also be connected to the outer wall of the first inflation chamber 111 by means including but not limited to high-frequency welding, hot-pressing connection, etc.

[0164] For example, see Figure 4 The second connecting portion 132 is disposed on the first bottom plate 1101 of the first inflation chamber 111, and the first connecting portion 131 is disposed on the second top plate 1202 of the second inflation chamber 122. The first connecting portion 131 and the second connecting portion 132 are detachably connected, and the air chamber communication assembly 13 can switch between a first state and a second state. For example, as shown... Figure 6 As shown, along the second direction Y, the second side surface 1320 of the second connecting portion 132 is opposite to and spaced apart from the first side piece 1104, and the first side surface 1310 of the first connecting portion 131 is opposite to and spaced apart from the second side piece 1203 or the first side piece 1104. When the first connecting portion 131 and the second connecting portion 132 are connected, the first side surface 1310 of the first connecting portion 131 and the second side surface 1320 of the second connecting portion 132 are parallel and opposite to each other.

[0165] In the first state, the first connecting portion 131 is at least partially located at the second connecting portion 132 and is sealed to the second connecting portion 132, and the second inflation chamber 122 and the first inflation chamber 111 are in communication. In the second state, the first connecting portion 131 is disengaged from the second connecting portion 132, and the second inflation chamber 122 and the first inflation chamber 111 are not in communication. When the second inflation chamber 122 and the first inflation chamber 111 need to be connected, the first connecting portion 131 can be inserted into the second connecting portion 132 by pressing, which switches the air chamber communication assembly 13 to the first state.

[0166] For example, both the first connecting part 131 and the second connecting part 132 are made of hard plastic. Hard plastic is sensitive to high temperatures and can deform when heated. This allows the first connecting part 131 and the second connecting part 132 to be disassembled by appropriately heating them, thus switching the air chamber communication assembly 13 to the second state. It is understood that the first connecting part 131 and the second connecting part 132 can also be disassembled by adjusting the hardness or softness of the materials, but this embodiment does not limit this.

[0167] For example, the first connecting part 131 and the second connecting part 132 are both made of materials that are not sensitive to high temperatures, that is, they will not deform after heating. Thus, the first connecting part 131 and the second connecting part 132 are not detachable, so that the air chamber communication assembly 13 cannot be switched from the first state to the second state.

[0168] The materials of the first connecting part 131 and the second connecting part 132 are not limited in this application embodiment. For example, they can also be polyvinyl chloride (PVC), thermoplastic urethanes (TPU), polyethylene terephthalate-vinyl acetate (PEVA), etc.

[0169] By adopting the above technical solution, and by setting a first connecting part 131 that is fluidly connected to the second inflation chamber 122 and a second connecting part 132 that is fluidly connected to the first inflation chamber 111, a modular design can be achieved. That is, the first connecting part 131 and the second inflation chamber 122 are one module, and the first inflation chamber 111 and the second connecting part 132 are another module. Even if any module is damaged, only the corresponding module needs to be replaced, which can reduce the probability of scrapping the entire product and has great benefits in terms of environmental protection and production cost control.

[0170] On the other hand, in the first state, the first connecting part 131 is at least partially located inside the second connecting part 132 and is sealed to the second connecting part 132. The second inflation chamber 122 and the first inflation chamber 111 are connected. The user can inflate and deflate the two chambers with just one inflation and deflation operation, which is simple to operate and highly efficient.

[0171] In some embodiments, see Figure 7 and combined Figure 5 , Figure 6The first connecting portion 131 includes a first through hole 1311, and the second connecting portion 132 includes a second through hole 1321. In a first state, the first connecting portion 131 is located within the second through hole 1321, and the first through hole 1311 is in fluid communication with either the second through hole 1321 or the first inflation chamber 111. The first connecting portion 131 includes a first wall 1312, and the second connecting portion 132 includes a second wall 1322. The first through hole 1311 is defined by the first wall 1312, meaning the first through hole 1311 is an internal channel of the first wall 1312. The first wall 1312 is at least partially disposed within the second through hole 1321, and the outer surface of the first wall 1312 abuts against the inner surface of the second wall 1322 that defines the second through hole 1321. The second inflation chamber 122 and the first inflation chamber 111 are connected through the first through hole 1311.

[0172] In some embodiments, see Figure 9 and combined Figure 7 , Figure 8 Along the first direction X, the first wall 1312 defines a first through hole 1311 and includes a first end 1313, a second end 1314 and a first intermediate portion 1317. The first intermediate portion 1317 is disposed between the first end 1313 and the second end 1314. The first end 1313 is used to connect to the second gas-filled outer wall. The second end 1314 of the first wall 1312 is provided with a snap-fit ​​protrusion 1315 protruding along the second direction Y.

[0173] Along the first direction X, the second wall 1322 defines the second through hole 1321 and includes a fourth end 1323, a third end 1324 and a second intermediate portion 1327. The second intermediate portion 1327 is disposed between the third end 1324 and the fourth end 1323. The third end 1324 is located in the first inflation chamber 111. The fourth end 1323 is used to connect with the outer wall of the first inflation chamber. The third end 1324 of the second wall 1322 is provided with a snap-fit ​​recess 1325 recessed along the second direction Y. In the first state, the snap-fit ​​protrusion 1315 snaps into the snap-fit ​​recess 1325 to fix the first connecting portion 131 to the second connecting portion 132.

[0174] like Figure 10 As shown, taking the example of the air nozzle 112 being located in the second inflation chamber 122, during inflation, gas (e.g., air) enters the second inflation chamber 122 through the air nozzle 112, then flows into the first inflation chamber 111 along arrow a through the first through hole 1311. This allows one chamber (e.g., the second inflation chamber 122) to be inflated, while the other chamber (e.g., the first inflation chamber 111) receives gas, ultimately balancing the air pressure in both chambers and completing the inflation. During deflation, simply open the air nozzle 112, and gas flows from the first inflation chamber 111 into the second inflation chamber 122 along arrow b through the first through hole 1311. Finally, the gas is discharged into the external environment through the air nozzle 112.

[0175] For example, see Figure 9 and combined Figure 7 , Figure 8 The snap-fit ​​recess 1325 includes an abutment surface 13251 extending along a second direction Y (e.g., a horizontal direction). Understandably, the abutment surface 13251 of the snap-fit ​​recess 1325 can also be changed from a horizontal structure to an inclined structure to achieve the effect of making the first connecting part 131 and the second connecting part 132 impossible to disassemble or easy to disassemble. Alternatively, the width of the abutment surface 13251 can also be changed to achieve the effect of making the first connecting part 131 and the second connecting part 132 impossible to disassemble or easy to disassemble.

[0176] For example, see Figure 10 and combined Figure 8 , Figure 9 In the first state, along the first direction X, the first wall 1312 will not protrude from the second through hole 1321, that is, the height h1 between the second end 1314 and the first end 1313 is greater than or approximately equal to the height h2 between the third end 1324 and the fourth end 1323. The second end 1314 of the first wall 1312 and the third end 1324 of the second wall 1322 are flush in the second direction Y. The height of the snap-fit ​​protrusion 1315 is less than or approximately equal to the height of the snap-fit ​​recess 1325. When the first connecting part 131 and the second connecting part 132 are connected by pressing, the snap-fit ​​protrusion 1315 can be completely located within the snap-fit ​​recess 1325, avoiding obstruction of the snap-fit ​​protrusion 1315 during installation and thus preventing installation from being affected. For example, in the first state, the combined height of the first connecting part 131 and the second connecting part 132 does not exceed 18mm, which will not affect the appearance and storage of the product.

[0177] Exemplarily, at least one of the second end 1314 and the fourth end 1323 includes a chamfered surface. Exemplarily, the chamfered surface of the fourth end 1323 is formed by a first inclined surface 13231, and the chamfered surface of the second end 1314 is formed by a second inclined surface 13141. When the first connecting portion 131 is inserted into the second connecting portion 132, the first inclined surface 13231 and the second inclined surface 13141 contact each other, providing a guiding force for the first wall 1312 to enter the second through hole 1321. This facilitates the rapid assembly of the first connecting portion 131 and the second connecting portion 132 by external force pressing, reduces the risk of damaging the second wall 1322, and makes the connection process of the first connecting portion 131 and the second connecting portion 132 smoother. It is understood that the embodiments of this application do not limit the type of chamfer; for example, it can be a rounded corner or a beveled corner. When the chamfer is a rounded corner, the corresponding inclined surface is arc-shaped (e.g., Figure 9 The second inclined plane (13141) in the middle.

[0178] In some embodiments, see Figure 10 and combined Figure 8 , Figure 9The first connecting portion 131 includes a first extension 1316, which is located at the first end 1313 of the first wall 1312 and is attached to the second inflatable outer wall of the second inflation chamber 122 (e.g., the second top plate 1202). The second connecting portion 132 includes a second extension 1326, which is located at the fourth end 1323 of the second wall 1322 and is attached to the first inflatable outer wall of the first inflation chamber 111 (e.g., the first bottom plate 1101).

[0179] The first extension 1316 is an annular shape surrounding the first wall 1312, and the second extension 1326 is an annular shape surrounding the second wall 1322. The first through hole 1311 and the second through hole 1321 are both cylindrical. In this embodiment, the shapes of the first through hole 1311, the second through hole 1321, the first extension 1316, and the second extension 1326 are not limited. For example, the first through hole 1311 and the second through hole 1321 can also be cylindrical, etc.

[0180] For example, the first extension 1316 and the first end 1313 include rounded corners, and the second extension 1326 and the fourth end 1323 include rounded corners. Thus, the outer sides of both the first connecting portion 131 and the second connecting portion 132 have no sharp edges, and by rounding the corners, damage to the first inflation 11 and the second inflation 12 can be avoided. It can be understood that the first extension 1316 can also be attached to the first inflation outer wall of the first inflation chamber 111 (e.g., the first bottom sheet 1101), and the second extension 1326 can be attached to the second inflation outer wall of the second inflation chamber 122 (e.g., the second top sheet 1202).

[0181] In some embodiments, see Figure 10 and combined Figure 11 A sealing structure is provided between the first wall 1312 and the second wall 1322. Exemplarily, the sealing structure includes a sealing ring 13122. The first wall 1312 has a sealing groove 13121, and the sealing ring 13122 is disposed within the sealing groove 13121. In a first state, the sealing ring 13122 abuts against the second wall 1322; or, the second wall 1322 has a sealing groove 13121, and the sealing ring 13122 is disposed within the sealing groove 13121. In a first state, the sealing ring 13122 abuts against the inner surface of the second wall 1322 and against the outer surface of the first wall 1312. Exemplarily, the first wall 1312 has two sealing grooves 13121, and correspondingly, each sealing groove 13121 contains a sealing ring 13122 (e.g., an O-ring silicone seal). Understandably, the number of sealing grooves 13121 and sealing rings 13122 in this application embodiment is not limited, for example, it can be 3, 4, 5, 6, 7, etc.

[0182] This application does not limit the type of sealing structure; for example, see the following: Figure 12 and combined Figure 13 The sealing structure includes ribs 13123. Exemplarily, the first wall 1312 has two ribs 13123, and the first wall 1312 does not have a sealing groove 13121. In a first state, the ribs 13123 are located on the inner surface of the second wall 1322 and abut against the outer surface of the first wall 1312; or, the ribs 13123 are located on the outer surface of the first wall 1312 and abut against the inner surface of the second wall 1322. This application does not limit the number of ribs 13123, for example, it can be 1, 3, 4, 5, 6, 7, etc. Exemplarily, the ribs 13123 and the first wall 1312 are integrally formed, but this application does not limit this; the ribs 13123 and the first wall 1312 can also be two independent components.

[0183] In the foregoing embodiments, for example Figure 10 As shown, during the inflation / deflation process, when the outer wall of the second inflation gas adheres to the end of the first through hole 1311 (e.g., the first extension 1316) along the first direction X, the first through hole 1311 may be adhered to the outer wall, preventing airflow from smoothly flowing between the first inflation chamber 111 and the second inflation chamber 122. Alternatively, during the inflation / deflation process, when the outer wall of the first inflation gas adheres to the end of the first through hole 1311 (e.g., the snap-fit ​​boss 1315) along the first direction X, the first through hole 1311 may be adhered to the outer wall, preventing airflow from smoothly flowing between the second inflation chamber 122 and the first inflation chamber 111. Understandably, it is also possible that both ends of the first through hole 1311 (e.g., the first extension 1316 and the snap-fit ​​boss 1315) may be adhered to the outer walls of both the first and second inflation gases simultaneously. In the aforementioned scenarios, inflation / deflation efficiency will be reduced.

[0184] Based on this, the air chamber communication assembly 13 provided in this application embodiment further includes a ventilation section 133, which is disposed on the first wall 1312 or the second wall 1322, or on both the first wall 1312 and the second wall 1322. Further, the ventilation section 133 can be disposed on the first side 1310 of the first connecting portion 131 and the second side 1320 of the second connecting portion 132. It is understood that the ventilation section 133 can be disposed solely on the first side 1310 of the first connecting portion 131 or the second side 1320 of the second connecting portion 132.

[0185] The first side 1310 refers to at least one of the first end 1313, the second end 1314, and the first intermediate portion 1317 of the first wall 1312, and the first side 1310 is disposed opposite to the first side piece 1104 or the second side piece 1203. The second side 1320 refers to at least one of the third end 1324 and the second intermediate portion 1327 of the second wall 1322, and the second side 1320 is disposed opposite to the first side piece 1104. The ventilation section 133 provided in this embodiment can prevent the first through hole 1311 from being blocked by the outer wall of the first gas filling chamber and / or the outer wall of the second gas filling chamber along the first direction X, thus preventing gas from flowing between the first inflation chamber 111 and the second inflation chamber 122 through the first through hole 1311 in the first direction X. Therefore, when the outer wall of the first gas filling chamber and / or the outer wall of the second gas filling chamber is blocked by the end of the first wall 1312 and / or the second wall 1322, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the ventilation section 133.

[0186] The specific form of the ventilation section 133 will be further explained below:

[0187] Figure 14 According to another specific embodiment of the present invention, a perspective view of the venting portion 133 of the air chamber communication assembly 13 in a first state is shown. In this embodiment, the venting portion 133 is provided at the first connecting portion 131 and the second connecting portion 132.

[0188] For example, Figure 14a and Figure 14b Cross-sectional views and exploded perspective views of the venting portion 133 of the air chamber communication assembly 13 provided in this application embodiment in a second state are shown respectively. The venting portion 133 is located at the first end 1313 of the first wall 1312 of the first connecting portion 131, ensuring fluid communication between the first through hole 1311 and the second inflation chamber 122. This prevents gas from being unable to flow between the second inflation chamber 122 and the first through hole 1311 when the outer wall forming the second inflation chamber 122 (e.g., the second substrate 1201) adheres to and blocks the end of the first through hole 1311 (e.g., the portion of the first end 1313 directly opposite the second substrate 1201). Meanwhile, the ventilation section 133 is also provided at the third end 1324 of the second wall 1322 of the second connecting section 132, so that the first through hole 1311 and the first inflation chamber 111 are kept in fluid communication, thereby preventing gas from flowing between the first inflation chamber 111 and the first through hole 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1102) is attached to and blocks the end of the first through hole 1311 (e.g., the part of the third end 1324 facing the first top plate 1102).

[0189] For example, the air chamber communication assembly 13 includes four protrusions 134, which surround and are spaced apart at the third end 1324. Along the first direction X, the four protrusions 134 protrude from the snap-fit ​​recess 1325 to define the second side surface 1320. Four first ventilation recesses 1341 are formed on the second side surface 1320, so that the first through hole 1311 and the first inflation chamber 111 are in fluid communication. This prevents gas from flowing between the first inflation chamber 111 and the first through hole 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1102) is attached to and blocks the end of the first through hole 1311 (e.g., the part of the third end 1324 facing the first top plate 1102). Meanwhile, the air chamber communication assembly 13 also includes four additional protrusions 134, which are arranged around and spaced apart from the first end 1313. Along the first direction X, the four protrusions 134 protrude from the first extension 1316 to define the first side surface 1310. Four second ventilation recesses 1342 are formed on the first side surface 1310, allowing fluid communication between the first through hole 1311 and the second inflation chamber 122. This prevents gas from being unable to flow between the second inflation chamber 122 and the first through hole 1311 when the outer wall of the second inflation chamber 122 (e.g., the second substrate 1201) adheres to and blocks the end of the first through hole 1311 (e.g., the portion of the first end 1313 facing the second substrate 1201). The aforementioned protrusions 134, the first ventilation recesses 1341, and the second ventilation recesses 1342 together define the ventilation section 133.

[0190] Figure 14c A cross-sectional view of the air chamber communication assembly 13 provided in an embodiment of this application in a first state is shown. Exemplarily, along the first direction X, when the second bottom plate 1201 is attached to the four protrusions 134 of the first end 1313 and the first top plate 1102 is attached to the four protrusions 134 of the third end 1324, the protrusions 134 can prevent the second bottom plate 1201 and the first top plate 1102 from sticking together and blocking the end of the first through hole 1311. Therefore, gas can still flow between the first air vent 1341 and the second air vent 1342 defined between two adjacent protrusions 134 on the third end 1324 and the first end 1313, respectively. Since the first vent recess 1341 is located on the second side 1320 and the second vent recess 1342 is located on the first side 1310, the fact that one end of the first through hole 1311 along the first direction X is blocked by the outer wall of the second gas filling 12 or the third end 1324 is blocked by the outer wall of the first gas filling 11 does not affect the flow of gas between the first gas filling chamber 111 and the second gas filling chamber 122. The vent 133 can prevent the third end 1324 and the first end 1313 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0191] Understandably, in this embodiment of the application, blockage refers to the inability of gas to flow smoothly between the second inflation chamber 122 and the first inflation chamber 111 through the first through hole 1311, thereby hindering the normal inflation and deflation of the inflatable product.

[0192] Figure 15 According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, the vent 133 is provided on the first connecting portion 131.

[0193] For example, Figure 15a and Figure 15b Cross-sectional view and exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state are shown respectively. In this embodiment, the vent 133 is provided at the second end 1314 of the first wall 1312 of the first connecting portion 131, so that the first through hole 1311 and the first inflation chamber 111 are kept in fluid communication. This prevents gas from flowing between the first inflation chamber 111 and the second inflation chamber 122 when the wall forming the first inflation chamber 111 (e.g., the first top plate 1102) is attached to and blocks the end of the first through hole 1311 (e.g., the part of the second end 1314 facing the first top plate 1102).

[0194] For example, the air chamber communication assembly 13 includes four protrusions 134, which surround and are spaced apart at the second end 1314. Along the first direction X, the four protrusions 134 protrude from the snap-fit ​​protrusions 1315 to define the first side surface 1310. Two adjacent protrusions 134 define four first ventilation recesses 1341 on the first side surface 1310. The four ventilation recesses 1341 together define the ventilation portion 133, so that the first through hole 1311 and the first inflation chamber 111 are in fluid communication. This prevents gas from flowing between the first inflation chamber 111 and the second inflation chamber 122 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) is attached to and blocks the end of the first through hole 1311 (e.g., the part of the second end 1314 facing the first top plate 1102).

[0195] Figure 15cA cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. Exemplarily, along the first direction X, when the first top piece 1102 is attached to the four protrusions 134 of the second end 1314 of the first connecting portion 131, the protrusions 134 can prevent the first top piece 1102 from covering the first through hole 1311. Therefore, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first venting recess 1341 defined between two adjacent protrusions 134 on the second end 1314. Since the first vent recess 1341 is located on the first side surface 1310, the fact that the end of the first through hole 1311 located in the first inflation chamber 111 is covered by the outer wall of the first inflation gas 11 does not affect the flow of gas between the first inflation chamber 111 and the second inflation chamber 122. This vent can prevent the second end 1314 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0196] Figure 16 According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, the vent 133 is provided on the first connecting portion 131.

[0197] For example, Figure 16a An exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state is shown. A vent 133 is provided at the first end 1313, ensuring fluid communication between the first through hole 1311 and the second inflation chamber 122. This prevents gas from being unable to flow between the second inflation chamber 122 and the first inflation chamber 111 when the outer wall forming the second inflation chamber 122 (e.g., the second substrate 1201) adheres to and blocks the end of the first through hole 1311 (e.g., the portion of the first end 1313 directly opposite the second substrate 1201).

[0198] Exemplarily, the air chamber communication assembly 13 includes four protrusions 134, which are arranged around and spaced apart at the first end 1313. Along the first direction X, the four protrusions 134 protrude from the first extension 1316 to define a first side surface 1310, in which four first ventilation recesses 1341 are formed. When the second substrate 1201 is attached to the four protrusions 134 at the first end 1313, the protrusions 134 can prevent the second substrate 1201 from covering the end of the first through hole 1311. Therefore, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first ventilation recesses 1341 defined between two adjacent protrusions 134 at the first end 1313. Since the first vent recess 1341 is located on the first side 1310, when one end of the first through hole 1311 along the first direction X is covered by the outer wall of the second gas filling 12, it does not affect the flow of gas between the first filling chamber 111 and the second filling chamber 122. This can prevent the first end 1313 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the gas chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0199] Figure 17 According to yet another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, the vent 133 is provided at the first connecting portion 131.

[0200] For example, Figure 17a and Figure 17b A cross-sectional view and an exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state are shown. In this embodiment, a vent 133 is provided at the first end 1313, allowing fluid communication between the first through hole 1311 and the second inflation chamber 122. This prevents gas from being unable to flow between the second inflation chamber 122 and the first through hole 1311 when the outer wall of the second inflation chamber 122 (e.g., the second substrate 1201) adheres to and blocks the end of the first through hole 1311 (e.g., the portion of the first end 1313 directly opposite the second substrate 1201). Meanwhile, the ventilation section 133 is also provided at the second end 1314, so that the first through hole 1311 and the first inflation chamber 111 are in fluid communication, thereby preventing gas from being unable to flow between the first inflation chamber 111 and the first through hole 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) is attached to and blocks the end of the first through hole 1311 (e.g., the part of the second end 1314 facing the first top plate 1102).

[0201] For example, the air chamber communication assembly 13 includes four protrusions 134, which surround and are spaced apart at the first end 1313. Along the first direction X, the four protrusions 134 protrude from the first extension 1316 to define the first side surface 1310. Four second ventilation recesses 1342 are formed on the first side surface 1310, so that the first through hole 1311 and the second inflation chamber 122 are in fluid communication. This prevents gas from flowing between the second inflation chamber 122 and the first through hole 1311 when the outer wall of the second inflation chamber 122 (e.g., the second substrate 1201) is attached to and blocks the end of the first through hole 1311 (e.g., the part of the first end 1313 facing the second substrate 1201). The air chamber communication assembly 13 also includes four additional protrusions 134, which are arranged around and spaced apart from the second end 1314. Along the first direction X, the four protrusions 134 protrude from the snap-fit ​​protrusions 1315 and form four first ventilation recesses 1341 on the second end 1314, so that the first through hole 1311 and the first inflation chamber 111 are in fluid communication. This prevents gas from being unable to flow between the first inflation chamber 111 and the first through hole 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1102) is attached to and blocks the end of the first through hole 1311 (e.g., the part of the second end 1314 facing the first top plate 1102).

[0202] Figure 17c A cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. Exemplarily, along the first direction X, when the second bottom plate 1201 is attached to the four protrusions 134 of the first end 1313 of the first connecting portion 131, and the first top plate 1102 is attached to the four protrusions 134 of the second end 1314 of the first connecting portion 131, the protrusions 134 can prevent the second bottom plate 1201 and the first top plate 1102 from sticking together and blocking the end of the first through hole 1311. Therefore, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first ventilation recess 1341 and the second ventilation recess 1342 defined between two adjacent protrusions 134 on the second end 1314 and the first end 1313, respectively. Since both the first vent recess 1341 and the second vent recess 1342 are located on the first side surface 1310, the fact that the two ends of the first through hole 1311 along the first direction X are covered by the outer walls of the first gas filling 11 and the second gas filling 12 does not affect the flow of gas between the first gas filling chamber 111 and the second gas filling chamber 122. This can prevent the first end 1313 and the second end 1314 from being blocked by the outer walls during inflation and deflation, ensuring that the inflation and deflation process of the gas chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0203] Figure 18According to yet another embodiment of the present invention, a cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, the vent 133 is provided at the second connecting portion 132.

[0204] For example, Figure 18a An exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state is shown. A vent 133 is provided at the third end 1324, allowing fluid communication between the first through hole 1311 and the first inflation chamber 111. This prevents gas from being unable to flow between the first inflation chamber 111 and the first through hole 1311 when the outer wall forming the first inflation chamber 111 (e.g., the first top plate 1101) adheres to and blocks the end of the first through hole 1311 (e.g., the portion of the second end 1314 facing the first top plate 1102).

[0205] Exemplarily, the air chamber communication assembly 13 includes four protrusions 134, which are arranged around and spaced apart at the third end 1324. Along the first direction X, the four protrusions 134 protrude from the snap-fit ​​recess 1325 to define the second side 1320. When the first top piece 1102 is attached to the four protrusions 134 at the third end 1324 of the second connecting portion 132, the protrusions 134 can prevent the first top piece 1102 from covering the first through hole 1311. Therefore, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first venting recess 1341 defined between two adjacent protrusions 134 on the third end 1324. Since the first ventilation recess 1341 is located on the first side 1310, the flow of gas between the first inflation chamber 11 and the second inflation chamber 122 is not affected when the third end 1324 along the first direction X is covered by the outer wall of the first inflation gas 11. This avoids the phenomenon of the third end 1324 being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0206] Figure 19 According to yet another embodiment of the present invention, a cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, a vent 133 is provided at the first connecting portion 131 and the second connecting portion 132.

[0207] For example, Figure 19aAn exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state is shown. A vent 133 is provided at the first end 1313, allowing fluid communication between the first through hole 1311 and the second inflation chamber 122. This prevents gas from being unable to flow between the second inflation chamber 122 and the first through hole 1311 when the outer wall of the second inflation chamber 122 (e.g., the second substrate 1201) adheres to and blocks the end of the first through hole 1311 (e.g., the portion of the first end 1313 directly opposite the second substrate 1201). Meanwhile, the ventilation section 133 is also provided at the second end 1314 and the third end 1324 of the second wall 1322, so that the first through hole 1311 and the first inflation chamber 111 are in fluid communication. This prevents gas from being unable to flow between the first inflation chamber 111 and the first through hole 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) is attached to and blocks the end of the first through hole 1311 (e.g., the part of the second end 1314 and the third end 1324 facing the first top plate 1102).

[0208] Exemplarily, the air chamber communication assembly 13 includes twelve protrusions 134, of which four protrusions 134 are arranged around and spaced apart at the third end 1324 along the first direction X, four protrusions 134 protruding from the snap-fit ​​recess 1325 to define the second side surface 1320, and four more protrusions 134 are arranged around and spaced apart at the second end 1314 along the first direction X, four protrusions 134 protruding from the snap-fit ​​protrusion 1315, and the remaining four protrusions 134 are arranged around and spaced apart at the first end 1313 along the first direction X, four protrusions 134 protruding from the first extension 1316. The protrusions 134 protruding from the snap-fit ​​protrusion 1315 and the first extension 1316 at the second end 1314 and the first end 1313 define the first side surface 1310.

[0209] When the first top piece 1102 is attached to the protrusion 134 of the second end 1314 and the third end 1324, the protrusion 134 can prevent the first top piece 1102 from sticking to and blocking the end of the first through hole 1311. Therefore, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first ventilation recess 1341 defined between two adjacent protrusions 134 on the second end 1314 and the third end 1324; and / or, when the second bottom piece 1201 is attached to the protrusion 134 of the first end 1313, the protrusion 134 can prevent the second bottom piece 1201 from sticking to and blocking the end of the first through hole 1311. Therefore, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the second ventilation recess 1342 defined between two adjacent protrusions 134 on the first end 1313. Therefore, when one end of the first through hole 1311 along the first direction X is blocked by the outer wall of the first gas filling 11 or the second gas filling 12, or when both ends of the first through hole 1311 along the first direction X are blocked by the outer walls of the first gas filling 11 and the second gas filling 12, the flow of gas between the first inflation chamber 111 and the second inflation chamber 122 is not affected. This can prevent the first end 1313, the second end 1314 and the third end 1324 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the gas chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0210] It is understood that the number of protrusions 134 and venting recesses 1341 is not limited in any embodiment of this application, and may be, for example, 2, 3, 5, 6, 7, 10, etc.

[0211] Figure 20 According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, a vent 133 is provided at the first connecting portion 131 and the second connecting portion 132.

[0212] For example, Figure 20a An exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state is shown. A vent 133 is provided at the second end 1314 and the third end 1324, allowing fluid communication between the first through hole 1311 and the first inflation chamber 111. This prevents gas from being unable to flow between the first inflation chamber 111 and the second inflation chamber 122 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1102) is fitted against and blocks the end of the first through hole 1311 (e.g., the portion of the third end 1324 facing the first top plate 1102, and the portion of the second end 1314 facing the first top plate 1102).

[0213] For example, the air chamber communication assembly 13 includes eight protrusions 134, of which four protrusions 134 are arranged around and spaced apart at the second end 1314 to define a first side surface 1310. Along the first direction X, the four protrusions 134 protrude from the snap-fit ​​protrusions 1315 to form four first ventilation recesses 1341 on the first side surface 1310. The remaining four protrusions 134 are arranged around and spaced apart at the third end 1324 to define a second side surface 1320. Along the first direction X, the four protrusions 134 protrude from the snap-fit ​​recesses 1325 to form four first ventilation recesses 1341 on the second side surface 1320.

[0214] When the first top piece 1102 is attached to the protrusion 134 of the second end 1314 and the third end 1324, the protrusion 134 can prevent the first top piece 1102 from sticking to and blocking the end of the first through hole 1311. Therefore, gas can still flow between the first air vent 1341 defined between the two adjacent protrusions 134 on the second end 1314 and the third end 1324. In this embodiment, since the first vent recess 1341 is provided on the first side 1310 and the second side 1320, the fact that one end of the first through hole 1311 along the first direction X is covered by the outer wall of the first gas filling 11 does not affect the flow of gas between the first gas filling chamber 111 and the second gas filling chamber 122. This can avoid the phenomenon that the second end 1314 and the third end 1324 are covered by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the gas chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0215] Figure 21 According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, the vent 133 is provided at the second connecting portion 132.

[0216] For example, Figure 21a and Figure 21bCross-sectional view and exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state are shown respectively. The ventilation section 133 is located at the third end 1324 and includes an annular body 135. The annular body 135 protrudes from the third end 1324 to define a second side surface 1320. Along the first direction X, the annular body 135 protrudes from the snap-fit ​​recess 1325. Four first through holes 1351 are spaced apart and arranged around the second side surface 1320 to define the ventilation section 133, allowing fluid communication between the first through holes 1311 and the first inflation chamber 111. This prevents gas from flowing between the first inflation chamber 111 and the second inflation chamber 122 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) partially blocks the first through holes 1311 by adhering to and obstructing the end of the annular body 135 along the first direction X.

[0217] Figure 21c A cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. Exemplarily, along the first direction X, when the first top plate 1102 is attached to the end of the annular body 135 directly opposite the first top plate 1102 in the first direction X and partially obstructs the first through hole 1311, gas can still flow between the first through hole 1311 and the first through hole 1351 provided on the annular body 135, preventing the third end 1324 of the second connection portion 132 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving inflation and deflation efficiency.

[0218] Figure 22 According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, the vent 133 is provided on the first connecting portion 131.

[0219] For example, Figure 22a and Figure 22bCross-sectional view and exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state are shown respectively. A vent 133 is provided at the second end 1314 and includes an annular body 135. The annular body 135 protrudes from the second end 1314 to define a first side surface 1310. Along the first direction X, the annular body 135 protrudes from a snap-fit ​​protrusion 1315, and four first through holes 1351 are spaced apart and arranged around the first side surface 1310 to define the vent 133. This allows fluid communication between the first through holes 1311 and the first inflation chamber 111, thereby preventing gas from flowing between the first inflation chamber 111 and the second inflation chamber 122 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) adheres to and blocks the end of the annular body 135 along the first direction X.

[0220] Figure 22c A cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. Exemplarily, along the first direction X, when the first top piece 1102 is attached to the end of the annular body 135 directly opposite the first top piece 1102 in the first direction X, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first through hole 1311 and the first through hole 1351 provided on the annular body 135. This prevents the second end 1314 of the first connecting portion 131 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving inflation and deflation efficiency.

[0221] Figure 23 According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, the vent 133 is provided on the first connecting portion 131.

[0222] For example, Figure 23aAn exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state is shown. A vent 133 is provided at the first end 1313 and includes an annular body 135 protruding from the first end 1313 to define a first side surface 1310. Along the first direction X, the annular body 135 protrudes from a first extension 1316. The first side surface 1310 is provided with four first through holes 1351 spaced apart and surrounding the first end. When the second substrate 120 is attached to the end of the annular body 135 at the first end 1313 along the first direction X, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first through holes 1351 and the first through holes 1311. Since the first through hole 1351 is located on the first side 1310, when the end of the annular body 135 along the first direction X is covered by the outer wall of the second gas filling 12, the flow of gas between the first filling chamber 111 and the second filling chamber 122 is not affected. This can prevent the first end 1313 of the first connecting part 131 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the gas chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0223] Figure 24 According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, the vent 133 is provided on the first connecting portion 131.

[0224] For example, Figure 24a and Figure 24bCross-sectional views and exploded perspective views of another embodiment of the air chamber communication assembly 13 in a second state are shown respectively. A vent 133 is provided at the first end 1313. The vent 133 is an annular body 135 protruding from the first end 1313 and the second end 1314 to define a first side surface 1310. Exemplarily, along the first direction X, the portion of the annular body 135 at the first end 1313 protrudes from the first extension 1316. Four first through holes 1351 are spaced apart and arranged around the annular body 135, allowing fluid communication between the first through holes 1311 and the second inflation chamber 122. This prevents gas from flowing between the second inflation chamber 122 and the first through holes 1311 when the outer wall of the second inflation chamber 122 (e.g., the second substrate 1201) adheres to and blocks the end of the annular body 135 along the first direction X. Meanwhile, the annular body 135 of the venting part 133 is also provided at the second end 1314. The portion of the annular body 135 located at the second end 1314 protrudes from the snap-fit ​​protrusion 1315. Four first through holes 1351 are spaced apart and arranged around the annular body 135, allowing the first through holes 1311 and the first inflation chamber 111 to be in fluid communication. This prevents gas from being unable to flow between the first inflation chamber 111 and the first through hole 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) is attached to and blocks the other end of the annular body 135 along the first direction X. Therefore, by providing annular bodies 135 with first through holes 1351 at the first end 1313 and the second end 1314 respectively, the problem of the end of the first connecting part 131 being attached to and blocked by the outer walls of the first inflation gas 11 and the second inflation gas 12, thus affecting the inflation and deflation efficiency of the inflatable product, can be effectively avoided.

[0225] Figure 24c A cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. Along the first direction X, when the first top plate 1102 is attached to the end of the annular body 135 directly opposite the first top plate 1102 in the first direction X, and / or the second bottom plate 1201 is attached to the end of the annular body 135 directly opposite the second bottom plate 1201 in the first direction X, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first through hole 1351 provided on the annular body 135. This can prevent the first end 1313 and the second end 1314 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0226] Figure 25According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, a vent 133 is provided at the first connecting portion 131 and the second connecting portion 132.

[0227] For example, Figure 25a An exploded perspective view of another embodiment of the air chamber communication assembly 13 in a second state is shown. The vent 133 is an annular body 135 disposed at a second end 1314 and a third end 1324. Exemplarily, along the first direction X, the annular body 135 is disposed at the second end 1314, protruding from the snap-fit ​​protrusion 1315 to define a first side surface 1310; simultaneously, the annular body 135 also protrudes from the third end 1324 to define a second side surface 1320, and along the first direction X, the annular body 135 protrudes from the snap-fit ​​recess 1325. Four first through holes 1351 are spaced apart and arranged around the annular body 135 on the second end 1314 and the third end 1324, so that the first through holes 1311 and the first inflation chamber 111 are in fluid communication. This prevents gas from being unable to flow between the first inflation chamber 111 and the second inflation chamber 122 when the outer wall of the first inflation chamber 111 (e.g., the first top piece 1102) is attached to and blocks the end of the annular body 135 along the first direction X. Therefore, when the first top plate 1102 is attached to the ends of the annular body 135 of the second end 1314 and the third end 1324, the gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first through hole 1311 and the first through hole 1351 provided on the annular body 135. This avoids the second end 1314 and the third end 1324 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0228] Figure 26 According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, a vent 133 is provided at the first connecting portion 131 and the second connecting portion 132.

[0229] For example, Figure 26a and Figure 26bCross-sectional views and exploded perspective views of another embodiment of the air chamber communication assembly 13 in a second state are shown. The venting section 133 includes an annular body 135, which protrudes from a first end 1313 and a third end 1324, defining a first side surface 1310 and a second side surface 1320, respectively. Exemplarily, the annular body 135 is located at the first end 1313, with a portion of the annular body 135 at the first end 1313 protruding from a first extension section 1316. The annular body 135 is provided with four spaced-apart and circumferential first through holes 1351, allowing fluid communication between the first through holes 1311 and the second inflation chamber 122. This prevents gas from being unable to flow between the second inflation chamber 122 and the first through holes 1311 when the outer wall of the second inflation chamber 122 (e.g., the second substrate 1201) adheres to and blocks one end of the annular body 135 along the first direction X. Meanwhile, an annular body 135 is also provided at the third end 1324. Along the first direction X, the portion of the annular body 135 at the third end 1324 protrudes from the snap-fit ​​recess 1325. The annular body 135 is provided with four first through holes 1351 spaced apart and surrounding it, so that the first through holes 1311 and the first inflation chamber 111 are in fluid communication. This prevents gas from being unable to flow between the first inflation chamber 111 and the first through holes 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) adheres to and blocks the other end of the annular body 135 along the first direction X. Therefore, by providing annular bodies 135 with first through holes 1351 at the first end 1313 and the third end 1324 respectively, the problem of the inflation and deflation efficiency of the inflatable product being affected by the outer walls of the first inflation gas 11 and the second inflation gas 12 being adhered to and blocked can be effectively avoided.

[0230] Figure 26c A cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. Along the first direction X, when the second bottom plate 1201 is attached to the end of the annular body 135 directly opposite the second bottom plate 1201 in the first direction X, and the first top plate 1102 is attached to the end of the annular body 135 directly opposite the first top plate 1102 in the first direction X, gas can still flow between the first through hole 1351 and the first through hole 1311 between the first inflation chamber 111 and the second inflation chamber 122. This prevents the first end 1313 and the third end 1324 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving inflation and deflation efficiency.

[0231] Figure 27According to yet another embodiment of the present invention, a cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, a vent 133 is provided at the first connecting portion 131 and the second connecting portion 132.

[0232] For example, Figure 27a A perspective view of another embodiment of the air chamber communication assembly 13 in a second state is shown. The venting section 133 includes three annular bodies 135. One annular body 135 is located at a first end 1313 along a first direction X. This annular body 135 protrudes from a first extension 1316 and is provided with four spaced-apart and circumferential first through holes 1351, allowing fluid communication between the first through holes 1311 and the second inflation chamber 122. This prevents the outer wall forming the second inflation chamber 122 (e.g., the second substrate 1201) from adhering to and blocking the end of the annular body 135 along the first direction X, thus preventing gas from flowing between the second inflation chamber 122 and the first inflation chamber 111 through the first through holes 1311.

[0233] Meanwhile, two other annular bodies 135 are respectively provided at the second end 1314 and the third end 1324. Along the first direction X, the annular bodies 135 are respectively provided with the snap-fit ​​protrusion 1315 and the snap-fit ​​recess 1325, and four first through holes 1351 are spaced apart and arranged around the annular body 135, so that the first through hole 1311 and the first inflation chamber 111 are in fluid communication, thereby preventing gas from being unable to flow between the first inflation chamber 111 and the second inflation chamber 122 when the outer wall of the first inflation chamber 111 (e.g., the first top piece 1101) is attached to and blocks the other end of the annular body 135 along the first direction X.

[0234] Therefore, when the first top sheet 1102 is attached to the end of the annular body 135 at the second end 1314 and the third end 1324, gas can still flow between the first inflation chamber 111 and the first through hole 1311 through the first through hole 1351, and / or, when the second bottom sheet 1201 is attached to the end of the annular body 135 at the first end 1313, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first through hole 1351. Therefore, when the end of the annular body 135 of the first end 1313 is covered by the outer wall of the first inflation gas 11, and / or when the ends of the annular body 135 of the second end 1314 and the third end 1324 are covered by the outer wall of the second inflation gas 12, the flow of gas between the first inflation chamber 111 and the second inflation chamber 122 is not affected. This can prevent at least one of the first end 1313, the second end 1314, and the third end 1324 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the gas chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0235] Figure 28 According to yet another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, a vent 133 is provided at the first connecting portion 131 and the second connecting portion 132.

[0236] For example, Figure 28a and Figure 28b Cross-sectional views and exploded perspective views of another embodiment of the air chamber communication assembly 13 in a second state are shown. The ventilation section 133 includes four second through holes 1331 and four third through holes 1332, respectively disposed on the first intermediate portion 1317 of the first wall 1312 and the second intermediate portion 1327 of the second wall 1322. The second through holes 1331 and third through holes 1332 are arranged opposite each other along the second direction Y and their positions correspond, allowing fluid communication between the first through hole 1311 and the first inflation chamber 111. This prevents gas from flowing between the first inflation chamber 111 and the first through hole 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) adheres to and blocks the end of the first through hole 1311 (e.g., the portion of the third end 1324 facing the first top plate 1102, and the portion of the second end 1314 facing the first top plate 1102).

[0237] Figure 28c A cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. Along the first direction X, when the first top plate 1102 is attached to the second end 1314 of the first connecting portion 131 and the third end 1324 of the second connecting portion 132, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the second through hole 1331 and the third through hole 1332. This avoids the second end 1314 and the third end 1324 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0238] Figure 29 According to another embodiment of the present invention, a perspective view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, a vent 133 is provided at the first connecting portion 131 and the second connecting portion 132.

[0239] For example, Figure 29a and Figure 29bCross-sectional views and exploded perspective views of another embodiment of the air chamber communication assembly 13 in a second state are shown. The ventilation section 133 includes four second through holes 1331 and four third through holes 1332, respectively disposed on the first intermediate portion 1317 of the first wall 1312 and the second intermediate portion 1327 of the second wall 1322. The second through holes 1331 and third through holes 1332 are arranged opposite each other along the second direction Y and their positions correspond, allowing fluid communication between the first through hole 1311 and the first inflation chamber 111. This prevents gas from flowing between the first inflation chamber 111 and the first through hole 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) adheres to and blocks the end of the first through hole 1311 (e.g., the portion of the third end 1324 facing the first top plate 1102, and the portion of the second end 1314 facing the first top plate 1102).

[0240] For example, the ventilation section 133 further includes an annular body 135, which protrudes from the first end 1313 to define the first side surface 1310. Along the first direction X, the annular body 135 protrudes from the first extension section 1316, and four first through holes 1351 are spaced apart and arranged around the annular body 135 for connecting the second inflation chamber 122 and the first through hole 1311. The aforementioned first through holes 1351, second through holes 1331, and third through holes 1332 together define the ventilation section 133.

[0241] Figure 29c A cross-sectional view of another embodiment of the vent 133 in a first state is shown. Along the first direction X, when the first top plate 1102 is attached to the second end 1314 of the first connecting portion 131 and the third end 1324 of the second connecting portion 132, and / or when the second bottom plate 1201 is attached to the end of the annular body 135 directly opposite the second bottom plate 1201 in the first direction X, since the first through hole 1351 and the second through hole 1331 are provided on the first side 1310 and the third through hole 1332 is provided on the second side 1320, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the first through hole 1351, the second through hole 1331 and the third through hole 1332. This can prevent the first end 1313 and / or the second end 1314 from being blocked by the outer wall of the second inflation gas 12 and / or the first inflation gas 11 during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0242] Figure 30 According to yet another embodiment of the present invention, a cross-sectional view of another embodiment of the air chamber communication assembly 13 in a first state is shown. In this embodiment, a vent 133 is provided at the first connecting portion 131 and the second connecting portion 132.

[0243] For example, Figure 30a A perspective view of another embodiment of the air chamber communication assembly 13 in a second state is shown. The vent 133 includes a protrusion 134 located at a first end 1313, allowing fluid communication between the first through hole 1311 and the second inflation chamber 122. This prevents gas from being unable to flow between the second inflation chamber 122 and the first through hole 1311 when the outer wall forming the second inflation chamber 122 (e.g., the second substrate 1201) adheres to and blocks the end of the first through hole 1311 (e.g., the portion of the first end 1313 directly opposite the second substrate 1201).

[0244] Furthermore, the ventilation section 133 also includes four second through holes 1331 and four third through holes 1332, which are respectively disposed on the first intermediate portion 1317 of the first wall 1312 and the second intermediate portion 1327 of the second wall 1322. The second through holes 1331 and the third through holes 1332 are arranged opposite to each other along the second direction Y and their positions correspond to each other, so that the first through hole 1311 and the first inflation chamber 111 are in fluid communication. This prevents gas from flowing between the first inflation chamber 111 and the first through hole 1311 when the outer wall of the first inflation chamber 111 (e.g., the first top plate 1101) is attached to and blocks the end of the first through hole 1311 (e.g., the part of the third end 1324 facing the first top plate 1102, and the part of the second end 1314 facing the first top plate 1102).

[0245] Therefore, when the first top sheet 1102 is attached to the second end 1314 and the third end 1324, gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the second through hole 1331 and the third through hole 1332. And / or, when the second bottom sheet 1201 is attached to the protrusion 134 of the first end 1313, the protrusion 134 can prevent the second bottom sheet 1201 from covering the end of the first through hole 1311, so that gas can still flow between the first inflation chamber 111 and the second inflation chamber 122 through the second through hole 1331 and the third through hole 1332. Therefore, the fact that the end of the first through hole 1311 along the first direction X is blocked by the outer wall of the first gas filling 11 and / or the second gas filling 12 does not affect the flow of gas between the first inflation chamber 111 and the second inflation chamber 122. This avoids at least one of the first end 1313, the second end 1314, and the third end 1324 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the gas chamber is always unobstructed, thereby improving inflation and deflation efficiency. It is understood that the embodiments of this application do not limit the number of the first through hole 1351, the second through hole 1331, and the third through hole 1332, for example, they can be 1, 2, 3, 5, 6, 7, 10, etc.

[0246] In some embodiments, see Figure 31 , Figure 31 This illustration shows a cross-sectional view of another embodiment of the air chamber communication assembly provided in this application, in a first state. The ventilation portion 133 of the air chamber communication assembly 13 includes a first airflow channel 136 and a second airflow channel 137. The first airflow channel 136 is disposed within a first intermediate portion 1317 of a first wall 1312 and includes a first opening 1361 and a second opening 1362. The second airflow channel 137 is disposed on a second intermediate portion 1327 of a second wall 1322 and aligned with the second opening 1362 of the first airflow channel 136. The outer surface of the first wall 1312 defines a first side surface 1310, and the outer and inner surfaces of the second wall 1322 define a second side surface 1320. The outer surface of the first wall 1312 is in contact with the inner surface of the second wall 1322. The first airflow channel 136 has a first opening 1361 in the first extension 1316 of the first end 1313. The first opening 1361 is disposed through the first intermediate portion 1317 and communicates with the second opening 1362. The second opening 1362 communicates with the second airflow channel 137.

[0247] Therefore, when the first top plate 1102 is attached to the second end 1314 of the first connecting portion 131 and the third end 1324 of the second connecting portion 132, and / or the second bottom plate 1201 is attached to the first end 1313 of the first connecting portion 131, the gas can still flow between the second inflation chamber 122 and the first inflation chamber 111 through the first airflow channel 136 and the second airflow channel 137. This can prevent at least one of the first end, the second end 1314, and the third end 1324 from being blocked by the outer wall during inflation and deflation, ensuring that the inflation and deflation process of the air chamber is always unobstructed, thereby improving the inflation and deflation efficiency.

[0248] Understandably, the airflow channel 136 can also be provided separately on the first wall 1312 or the second wall 1322, and the second opening 1362 can be provided on the first wall 1312 or the second wall 1322.

[0249] It should be noted that the embodiments of this application do not specifically limit the structure of the venting part 133. For example, the foregoing embodiments list at least five forms of the venting part 133: the venting part 133 includes multiple protrusions 134; the venting part 133 includes an annular body 135; the venting part 133 includes multiple protrusions 134 and an annular body 135; the venting part 133 includes a second through hole 1331 and a third through hole 1332; and the venting part includes a first airflow channel and a second airflow channel. These five forms of venting parts can be arranged in any combination on the first connecting part 131 and the second connecting part 132, or they can be arranged in any combination individually on the first connecting part 131 or the second connecting part 132.

[0250] Those skilled in the art will understand that if an inflatable chamber is filled with sponge, other substances, or if the material of the inflatable chamber is not easily adhered to at least one of the first end 1313, the second end 1314, and the third end 1324, then the first wall 1312 of the first connecting portion 131 and / or the second wall 1322 of the second connecting portion 132 may optionally not require an additional ventilation portion 133. If both chambers are simply inflatable chambers, then both the first wall 1312 of the first connecting portion 131 and the second wall 1322 of the second connecting portion 132 need to be provided with ventilation portions 133. For example, if the second inflation chamber 122 is filled with sponge, other substances, or the material of the inflation chamber is not easily adhered to the outer wall, then optionally, a vent 133 is not required on the first end 1313 of the first wall 1312 of the first connecting portion 131 of the second inflation chamber 122; instead, a vent 133 can be provided on the second wall 1322 and / or the second end 1314 of the first wall 1312 of the second connecting portion 132. In some embodiments, see [reference]. Figure 28 , Figure 29 and in conjunction with the appendix Figure 2 Along the first direction X, the first gas 11 is stacked on top of the second gas 12, and the first gas 11 and the second gas 12 are detachably connected.

[0251] For example, the second top plate 1202 of the second gas filling 12 is in contact with the first bottom plate 1101 of the first gas filling 11. The first gas filling 11 and the second gas filling 12 are detachably connected only through the gas chamber communication assembly 13, and are not connected by the connecting piece 123 (e.g., Figure 3 (As shown). By adopting the above technical solution, the first inflation gas 11 can rotate relative to the second inflation gas 12, which can increase the operability of the inflatable product, thereby increasing the flexibility and fun of using the car mattress 10, and forming a modular design, that is, the first inflation gas 11 is one module and the second inflation gas 12 is another module.

[0252] In some embodiments, the first gas 11 and the second gas 12 may be further connected to enhance the stability of the first gas 11 and the second gas 12. For example, see [link to documentation]. Figure 32 The car mattress also includes a connecting piece 123, which connects to the second inflation gas 12 and the first inflation gas 11. One side of the connecting piece 123 is located at the junction of the second top piece 1202 and the second side piece 1203, and the connecting piece 123 is located on the long side (parallel to the second direction Y) of the first inflation gas 11. The other side of the connecting piece 123 is connected to the first top piece 1102.

[0253] Understandably, the connecting piece 123 can also be located on the short side (parallel to the third direction Z) of the first gas filling 11, or simultaneously on both the long and short sides of the first gas filling 11; this application does not limit this. Each connecting piece 123 can also be composed of two pieces of material, such as a second top piece and a second bottom piece, where one piece of material, such as the second top piece, is connected to the first gas filling 11, and the other piece of material, such as the second bottom piece, is connected to the second gas filling 12. The two pieces of material of the connecting piece 123 can be connected by welding or gluing to form a fixed connecting piece 123, or the two pieces of material of the connecting piece 123 can be connected by zippers, buttons, or Velcro to form a detachable connecting piece 123.

[0254] Furthermore, this application does not limit the connection method between the first gas filling 11 and the second gas filling 12. For example, see [reference needed]. Figure 32 , Figure 33 and in conjunction with the appendix Figure 2 The first top sheet 1102 (i.e., the surface of the first gas filling 11) and the second top sheet 1202 (i.e., the surface of the second gas filling 12) are connected by a connecting piece 123, or the first top sheet 1102 and the second side sheet 1203 of the second gas filling 12 are connected by a connecting piece 123. Exemplarily, the first bottom sheet 1101 (i.e., the bottom sheet of the first gas filling 11) and the second top sheet 1202 are connected by a connecting piece 123, or the first bottom sheet 1101 and the second side sheet 1203 are connected by a connecting piece 123.

[0255] It is understood that the connection method of the first gas filling 11 and the second gas filling 12 is not limited to this. For example, the first bottom sheet 1101 can be connected to the second top sheet 1202 and the second side sheet 1203 simultaneously through the connecting piece 123, and the first top sheet 1102 can be connected to the second top sheet 1202 and the second side sheet 1203 simultaneously through the connecting piece 123. It is understood that the embodiments of this application do not limit the specific connection process of the aforementioned connection method, such as including but not limited to high-frequency welding, hot pressing connection, or providing a zipper on the first gas filling 11 and the second gas filling 12 to achieve a detachable connection.

[0256] In some embodiments, see Figure 32 , Figure 33 and in conjunction with the appendix Figure 2The concave-convex structure 121 includes a first protrusion 1211, a second protrusion 1212, a third protrusion 1213, a first recess 1214, and a second recess 1215. Specifically, the first protrusion 1211 mates with the recesses at the first seat cushion 201 and the first backrest 202 of the front seat 20. The second protrusion 1212 mates with the recesses at the first backrest 202 of the front seat 20. The third protrusion 1213 mates with the recesses at the second seat cushion 203 and the second backrest 204 of the rear seat 20. The first recess 1214 mates with the protrusion at the first backrest 202 of the front seat 20. The second recess 1215 mates with the protrusions adjacent to the first backrest 202 of the front seat 20 and the second seat cushion 203 of the rear seat 20.

[0257] For example, on the first top piece 1102, along the second direction Y, a first protrusion 1211 and a second protrusion 1212 are adjacent, and a third protrusion 1213 and a second protrusion 1212 are adjacent. The second protrusion 1212 is disposed between the first protrusion 1211 and the third protrusion 1213. A first recess 1214 is formed between the first protrusion 1211 and the second protrusion 1212, and a second recess 1215 is formed between the second protrusion 1212 and the third protrusion 1213. The first protrusion 1211 engages with the first recess 211, the first recess 1214 engages with the first protrusion 212, the second protrusion 1212 engages with the second recess 213, the second recess 1215 engages with the second protrusion 215, and the third protrusion 1213 engages with the third recess 214.

[0258] In some embodiments, see Figure 32 , Figure 33 and in conjunction with the appendix Figure 2 Along the second direction Y, the second inflation chamber 122 sequentially includes a first region 1221, a second region 1222, and a third region 1223. A first protrusion 1211 is provided in the first region 1221, a second protrusion 1212 is provided in the second region 1222, and a third protrusion 1213 is provided in the third region 1223. Along the first direction X, the maximum height of the first region 1221 and the third region 1223 is not less than the maximum height of the second region 1222.

[0259] That is, the maximum height of the first protrusion 1211 and the third protrusion 1213 is not less than the maximum height of the second protrusion 1212. The second substrate 1201 forms a lower surface with varying heights, so that the concave-convex structure 121 can match the concave-convex portion 21 generated when the front seat of the vehicle is in a flat position. The height relationship between the first region 1221, the second region 1222, and the third region 1223 is not limited. In other embodiments, the height relationship between the first region 1221, the second region 1222, and the third region 1223 can be changed according to different concave-convex portions 21 of the seat 20.

[0260] For example, on the second film 1201, a first region 1221 is provided on the first seat cushion 201 and part of the first backrest 202, a second region 1222 is provided on the first backrest 202, and a third region 1223 is provided on the second seat cushion 203.

[0261] In some embodiments, see Figure 32 , Figure 33 and in conjunction with the appendix Figure 2 The second inflation 12 includes an arcuate portion 12221, and the width of the second base plate 1201 narrows at the arcuate portion 12221. Along the third direction Z, the width of the second region 1222 is no greater than the width of the first region 1221, and the width of the second region 1222 is no greater than the width of the third region 1223. Exemplarily, along the third direction Z, the two sides of the second region 1222 include arcuate portions 12221 that converge and narrow towards each other. Since the first backrest 202 is generally concave in its flat state, the narrowed arcuate portion 12221 of the second region 1222 can match the corresponding concave shape, further improving the stability of the car mattress 10. The position of the arcuate portion 12221 is not limited; in other embodiments, the arcuate portion 12221 can be positioned at other locations on the second inflation 12 according to the shape of the seat 20.

[0262] In some embodiments, see Figure 32 , Figure 33 and in conjunction with the appendix Figure 2 The second inflation chamber 12 includes several sets of tensioning members, which are located in the second inflation chamber 122 and connected to the second bottom plate 1201 and the second top plate 1202. The several sets of tensioning members have different heights.

[0263] Exemplarily, the plurality of tensioning members include a first group of tensioning members 124, a second group of tensioning members 125, and a third group of tensioning members 126. The first group of tensioning members 124 is disposed in a first region 1221, the second group of tensioning members 125 is disposed in a second region 1222, and the third group of tensioning members 126 is disposed in a third region 1223. Along the first direction X, the upper and lower sides of each tensioning member are respectively connected to the second base plate 1201 and the second top plate 1202. Exemplarily, each tensioning member is connected to the second base plate 1201 and the second top plate 1202 by high-frequency welding, hot melting, adhesive bonding, or other connection methods. After being tensioned, the tensioning members provide tension to the second base plate 1201 and the second top plate 1202 to limit the deformation of the first inflatable gas 11, so that the first inflatable gas 11 can maintain a preset shape after being inflated, such as maintaining a convex or concave state.

[0264] Optionally, the plurality of tensioning members may have different structures in different embodiments. For example, each tensioning member may be a sheet-like tensioning member or a wire-like tensioning member.

[0265] Sheet-shaped tensioning components can have single-layer or composite-layer structures depending on actual needs.

[0266] When the sheet-like tensioning member is a single-layer sheet, it can be made of a polymer material, which may include, but is not limited to, one or more of polyvinyl chloride (PVC), polyurethane (PU), thermoplastic polyurethanes (TPU), polyethylene terephthalate (PET), ethylene-vinyl acetate (EVA) copolymer, and nylon. Understandably, in other embodiments, the main body of the single-layer sheet-like tensioning member may also be made of materials other than polymer materials, such as fabric materials, wherein the fabric material may optionally be finely woven or form a mesh structure. The fabric material may be, but is not limited to, natural fiber fabrics (e.g., but not limited to, cotton, linen, wool, and silk) or synthetic fiber fabrics (e.g., but not limited to, polyester, polyethylene, and polypropylene fabrics).

[0267] When the sheet-like tensioning member is a composite sheet, it consists of two or more layers of sheet material bonded together by adhesive, welding or other means, and each layer of the multilayer sheet material can be made of the polymer material as described above or other materials as described above.

[0268] The linear tensioning member comprises one or more threads that span the distance between the second base sheet 1201 and the second top sheet 1202 of the inflatable product, and may optionally be parallel or substantially parallel in space, for example, the threads being spaced apart from each other at equal intervals or in a manner that varies according to a certain pattern. The material of the one or more threads in the linear tensioning member may be, but is not limited to, natural fibers (e.g., but not limited to, cotton, linen, wool, and silk) or synthetic fibers (e.g., but not limited to, polyester, polyethylene, and polypropylene). The linear tensioning member is typically indirectly connected to the second base sheet 1201 and the second top sheet 1202 via a connector, which may be made of a polymeric material, but is not limited to, that facilitates welding of the second base sheet 1201 and the second top sheet 1202.

[0269] In some embodiments, see Figure 32 , Figure 33 , Figure 34 and in conjunction with the appendix Figure 2The first group of tensioning members 124 includes nine first tensioning members 1241. The nine first tensioning members 1241 are spaced apart along the second direction Y in the first region 1221. Along the first direction X, the first tensioning member 1241 at the middle position of the first region 1221 has a first height h3, and the first tensioning members 1241 at both ends of the first region 1221 have a second height h4. The first height h3 is greater than the second height h4.

[0270] For example, the height of the nine first tensioning members 1241 increases and then decreases along the length direction (e.g., the second direction Y) of the car mattress, exhibiting a normal distribution that is low at both ends and high in the middle. This makes the protruding portion of the first protrusion 1211 smoother, less likely to damage the seat 20, and provides better stability. In some embodiments, see [reference to...] Figure 32 , Figure 33 , Figure 34 and in conjunction with the appendix Figure 2 Along the second direction Y, the height of the plurality of first tensioning members 1241 located at the middle position opposite to the two ends decreases sequentially from the first height h3 to the second height h4. It is understood that the number of first tensioning members 1241 in this application embodiment is not limited, for example, it can also be 7, 8, 10, 11, 12, etc.

[0271] In some embodiments, see Figure 32 , Figure 33 , Figure 34 and in conjunction with the appendix Figure 2 The second set of tensioning members 125 includes six second tensioning members 1251, which are spaced apart along the second direction Y in the second region 1222. The heights of the six second tensioning members 1251 are basically equal, and each second tensioning member 1251 has a second height h4. Using the above technical solution, the equal heights of the multiple second tensioning members 1251 allow for a good match with the smaller recesses of the backrest. Furthermore, the fact that each second tensioning member 1251 has a second height h4 means that the height of the second tensioning members 1251 in the second region 1222 is the same as the height of the lowest first tensioning member 1241 in the first region 1221. This makes the connection between the first protrusion 1211 and the second protrusion 1212 smoother, less likely to damage the seat 20, and provides better stability.

[0272] Understandably, the number of the second tensioning member 1251 is not limited in the embodiments of this application. For example, it can be 5, 7, 8, 10, 11, 12, etc.

[0273] In some embodiments, see Figure 32 , Figure 33 , Figure 34 and in conjunction with the appendix Figure 2The third set of tensioning members 126 includes five third tensioning members 1261, the height of which gradually increases along the length direction of the car mattress (e.g., the second direction Y). For example, along the second direction Y, the five third tensioning members 1261 are spaced apart in the third region 1223. The third tensioning member 1261 at one end of the third region 1223 near the second region 1222 has a second height h4, and the third tensioning member 1261 at the other end of the third region 1223 has a first height h3. With this technical solution, the third tensioning member 1261 at one end of the third region 1223 has a second height h4, meaning the height of the lowest third tensioning member 1261 in the third region 1223 is the same as the height of the second tensioning member 1251 in the second region 1222. This makes the connection from the second protrusion 1212 to the third protrusion 1213 smoother, less likely to damage the seat 20, and provides better stability.

[0274] In some embodiments, see Figure 32 , Figure 33 , Figure 34 and in conjunction with the appendix Figure 2 Along the second direction Y, the height of the plurality of third tensioning members 1261 at one end of the third region 1223 opposite to the other end of the third region 1223 increases sequentially from the second height h4 to the first height h3. Using the above technical solution, the height of the plurality of third tensioning members 1261 at one end of the third region 1223 opposite to the other end increases sequentially from the second height h4 to the first height h3. That is, the height of the tallest first tensioning member 1241 in the first group of tensioning members 124 is the same as the height of the tallest third tensioning member 1261 in the third group of tensioning members 126, making the third protrusion 1213 more widely applicable, for example, it can be used to mate with the concave and convex parts of the rear seat 20.

[0275] Understandably, the number of the third tensioning member 1261 is not limited in the embodiments of this application. For example, it can be 4, 7, 8, 10, 11, 12, etc.

[0276] In some embodiments, see Figure 32 , Figure 33 , Figure 34 and in conjunction with the appendix Figure 2 Along the first direction X, each of the aforementioned tensioning members (e.g., the first tensioning member 1241, the second tensioning member 1251, and the third tensioning member 1261) includes a first side 127 and a second side 128. The first side 127 is connected to the second bottom piece 1201, and the second side 128 is connected to the second top piece 1202.

[0277] For example, several tensioning members include trapezoidal tensioning members, where the length of the first side 127 of the trapezoidal tensioning member is less than the length of the second side 128. That is, the length of the second side 128 along the third direction Z is greater than the length of the first side 127 along the third direction Z. For example, some tensioning members have a longer second side 118 near the first inflation gas 11 and a shorter first side 127 away from the first inflation gas 11, and their projections along the second direction Y are all trapezoidal, which can better support the first inflation gas 11. Specifically, the second tensioning members 1251 in the second group of tensioning members 125 are all trapezoidal, and the width of the second base plate 1201 is narrowed at the second region 1222 to accommodate the second group of tensioning members 125, thereby forming an arc 12221.

[0278] Understandably, the shape of the tensioning member is not limited in the embodiments of this application. For example, it can also be a rectangular shape, in which case the length of the first side 127 of the rectangular tensioning member is equal to the length of the second side 128. The arrangement and quantity ratio of the trapezoidal tensioning members and the rectangular tensioning members can be adjusted according to the needs of the concave-convex structure 121. For example, referring to... Figure 2 and Figure 26 In the first group of tensioning members 124, the three taller first tensioning members 1241 in the middle section are rectangular tensioning members, while the remaining shorter first tensioning members 1241 are trapezoidal tensioning members. In other embodiments, all the first tensioning members 1241 in the first group of tensioning members 124 may be trapezoidal or rectangular tensioning members, or the taller first tensioning members 1241 in the middle section may be trapezoidal tensioning members, while the remaining shorter first tensioning members 1241 are rectangular tensioning members, and so on.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
