Description

Technical Field

[0001] This utility model relates to the field of inflatable products, and in particular to an air chamber communication structure for inflatable products. 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. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that inflatable products cannot be modularly designed in the prior art. This invention provides a connected air chamber structure for inflatable products, which enables modular design between different air chambers of the inflatable product, improving production efficiency and reducing production costs.

[0006] To solve the above-mentioned technical problems, the present invention discloses an air chamber communication structure for an inflatable product, comprising:

[0007] The first gas filling includes:

[0008] First outer wall;

[0009] The first air chamber is defined by the first outer wall;

[0010] The first connecting part includes:

[0011] The first through hole is in fluid communication with the first air chamber;

[0012] The first end is connected to the first outer wall; and

[0013] The second end is located outside the first air chamber;

[0014] The second gas filling includes:

[0015] Second outer wall;

[0016] The second air chamber is defined by the second outer wall;

[0017] The second connecting part includes:

[0018] The second through hole is in communication with the fluid in the second air chamber;

[0019] The third end is connected to the second outer wall; and

[0020] Fourth end;

[0021] Wherein, the first connecting part is at least partially located in the second through hole and is sealed to the second connecting part; the first through hole is in fluid communication with the second through hole or the second air chamber.

[0022] By adopting the above technical solution, and by setting a first connecting part that is fluidly connected to the first air chamber and a second connecting part that is fluidly connected to the second air chamber, the larger complete body of the inflatable product can be designed and manufactured in different parts, realizing the modular production of the inflatable product. For example, the first connecting part and the first air chamber are one module, and the second air chamber and the second connecting part are 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 after-sales service can also be realized through modular design, which can reduce the probability of scrapping the entire product and has great benefits in terms of environmental protection and production cost control.

[0023] On the other hand, the first connecting part is at least partially located in the second through hole and is sealed to the second connecting part. The first through hole is in fluid communication with the second through hole or the second air chamber, and the user can charge and deflate both air chambers with only one charge and deflate operation, which is simple to operate and highly efficient.

[0024] According to another specific embodiment of the present invention, an embodiment of the present invention discloses an air chamber communication structure for an inflatable product, wherein the fourth end of the second connecting part is located inside the second air chamber.

[0025] According to another specific embodiment of the present invention, an air chamber communication structure for an inflatable product is disclosed. The second end of the first connecting part further includes a snap-fit ​​protrusion, and the fourth end of the second connecting part further includes a snap-fit ​​recess. The snap-fit ​​protrusion is located in the snap-fit ​​recess to snap the first connecting part and the second connecting part together.

[0026] 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 first air chamber and the second air chamber can rotate relative to each other under the action of external force, which can provide flexibility for inflatable products and improve the user experience.

[0027] According to another specific embodiment of the present invention, an air chamber communication structure for an inflatable product is disclosed. The first connecting part includes a first hole wall, the second connecting part includes a second hole wall, the first hole wall is located inside the second hole wall, and a sealing structure is provided between the first hole wall and the second hole wall.

[0028] According to another specific embodiment of the present invention, the embodiment of the present invention discloses an air chamber communication structure for an inflatable product, wherein the sealing structure is a rib ring; the rib ring is integrally disposed on the outer side of the first hole wall and abuts against the inner side of the second hole wall, or the rib ring is integrally disposed on the inner side of the second hole wall and abuts against the outer side of the first hole wall.

[0029] By adopting the above technical solution, a rib ring is set between the first hole wall and the second hole 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.

[0030] According to another specific embodiment of the present invention, an air chamber communication structure for an inflatable product is disclosed, wherein the sealing structure is at least one sealing ring, and the at least one sealing ring abuts against the inner side of the second hole wall and abuts against the outer side of the first hole wall.

[0031] According to another specific embodiment of the present invention, an embodiment of the present invention discloses an air chamber communication structure for an inflatable product, wherein at least one of the first connecting part and the second connecting part includes a sealing groove, and the at least one sealing ring is located in the sealing groove.

[0032] By adopting the above technical solution, a sealing ring is set between the first hole wall and the second hole 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.

[0033] According to another specific embodiment of the present invention, an embodiment of the present invention discloses an air chamber communication structure for an inflatable product, wherein the height h1 of the first connecting part is less than or equal to the height h2 of the second connecting part.

[0034] According to another specific embodiment of the present invention, an embodiment of the present invention discloses an air chamber communication structure for an inflatable product, wherein the height of the snap-fit ​​protrusion is less than or equal to the height of the snap-fit ​​recess.

[0035] 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 hole wall does not protrude from the second through hole, thus avoiding damage to the fabric of the second air chamber by the first hole wall protruding.

[0036] According to another specific embodiment of the present invention, an embodiment of the present invention discloses an air chamber communication structure for an inflatable product, wherein the first end of the first connecting part includes a first extension section, the first extension section being fixedly connected to the first outer wall of the first inflatable gas; the third end of the second connecting part includes a second extension section, the second extension section being fixedly connected to the second outer wall of the second inflatable gas.

[0037] By adopting the above technical solution, the first extension of the first connecting part is fixedly connected to the first outer wall of the first gas chamber, and the second extension of the second connecting part is fixedly connected to the second outer wall of the second gas chamber, which can enhance the connection stability between the first connecting part and the second gas chamber, as well as enhance the connection stability between the second connecting part and the first gas chamber.

[0038] According to another specific embodiment of the present invention, an embodiment of the present invention discloses an air chamber communication structure for an inflatable product, wherein the second end includes a second inclined surface and forms a chamfer to facilitate the insertion of the second end into the second through hole.

[0039] According to another specific embodiment of the present invention, an embodiment of the present invention discloses an air chamber communication structure for an inflatable product, wherein the third end includes a first inclined surface and forms a chamfer to facilitate the insertion of the second end into the second through hole.

[0040] 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. Attached Figure Description

[0062] 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.

[0063] See Figure 1This application 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 and the concave-convex structure 121 are in concave-convex fit, that is, the concave-convex structure 121 of the car mattress 10 can be used to fill the concave-convex portion 21 of the seat 20, thereby making the car mattress 10 more stable during use.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] In some embodiments, see Figure 1 , Figure 2 The car mattress 10 provided in this application embodiment includes a second inflation gas 11 and a first inflation gas 12. Along the first direction X, the second inflation gas 11 is disposed above the first inflation gas 12. The first inflation gas 12 includes the aforementioned concave-convex structure 121, which is disposed on the side of the first inflation gas 12 facing away from the second 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.

[0068] Using the above technical solution, the first 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 second inflation 11 flat, improving the user experience.

[0069] In some embodiments, see Figure 1 , Figure 2 The first inflation gas 12 includes a first piece 1201, a second piece 1202, and a side piece 1203. The first piece 1201, the second piece 1202, and the side piece 1203 together form the first outer wall of the first inflation gas 12 and together enclose the first air chamber 122. The concave-convex structure 121 is provided on the first piece 1201, that is, the first piece 1201 contacts the concave-convex portion 21 of the seat 20. Along the first direction X, the second inflation gas 11 is provided on the side of the second piece 1202 facing away from the first piece 1201. Exemplarily, the 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 limitations on this.

[0070] In some embodiments, see Figure 1 , Figure 2 The second gas filling 11 includes a third piece 1101, a fourth piece 1102, and a sponge filling part 1103. Along the first direction X, the sponge filling part 1103 is disposed between the third piece 1101 and the fourth piece 1102. The third piece 1101 is in contact with the second piece 1102. The third piece 1101 and the fourth piece 1102 together form the second outer wall of the second gas filling 11 and together enclose the second air chamber 111. The sponge filling part 1103 fills the second air chamber 111.

[0071] Exemplarily, the second inflation gas 11 and the first inflation gas 12 may or may not be connected. The second inflation gas 11 is filled with a sponge filling portion 1103, and the first piece 1201 of the first inflation gas 12 contacts the seat 20. The first inflation gas 12 provides a flat placement platform for the second inflation gas 11, allowing the user to lie flat on the second inflation gas 11. It is understood that the second 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.

[0072] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The second inflation gas 11 includes an air nozzle 112, which is located at the chamfered corners of the third piece 1101 and the fourth piece 1102. The air nozzle 112 is used to inflate or deflate the second inflation gas 11. When the second inflation gas 11 and the first inflation gas 12 are connected, the first inflation gas 12 is also inflated or deflated through the air nozzle 112. Due to the limited space inside the vehicle, 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 chamfered corners of the third piece 1101 and the fourth piece 1102. Because a small space is left at the chamfered corners, it is sufficient for the user to access the air nozzle 112, thus facilitating inflation or deflation.

[0073] In the description of this application, after the pressure of the gas (e.g., air) in the first air chamber 122 and the second air chamber 111 reaches the required value, the car mattress 10 is inflated and maintains a preset shape; while when the gas in the first air chamber 122 and the second air 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.

[0074] 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.

[0075] Figures 4 to 13This application illustrates an air chamber communication structure 13 for an inflatable product (e.g., a car mattress), wherein a first air chamber 122 and a second air chamber 111 are fluidly connected through the air chamber communication structure 13.

[0076] In some embodiments, see Figure 4 , Figure 5 , Figure 6 The car mattress 10 also includes an air chamber communication structure 13, which includes a first connecting part 131 and a second connecting part 132. The first connecting part 131 is located in the first air chamber 122, and the second connecting part 132 is located in the second air chamber 111.

[0077] Understandably, the embodiments of this application do not limit the positions of the first connecting portion 131 and the second connecting portion 132. For example, the first connecting portion 131 may also be provided in the second air chamber 111, and the second connecting portion 132 may be provided in the first air chamber 122. Exemplarily, the first connecting portion 131 may be provided in the third piece 1101, and the second connecting portion 132 may be provided in the second piece 1202, or the first connecting portion 131 may be provided in the second piece 1202, and the second connecting portion 132 may be provided in the third piece 1101.

[0078] For ease of understanding, the following description will take the example of a first connecting part 131 located in a first air chamber 122 and a second connecting part 132 located in a second air chamber 111. The first connecting part 131 can be connected to the sheet material of the first air chamber 122 by means including but not limited to high-frequency welding and hot-pressing, and the second connecting part 132 can also be connected to the sheet material of the second air chamber 111 by means including but not limited to high-frequency welding and hot-pressing.

[0079] For example, see Figure 4 , Figure 5 , Figure 6 The second connecting part 132 is provided on the third piece 1101 of the second air chamber 111, and the first connecting part 131 is provided on the second piece 1202 of the first air chamber 122. The first connecting part 131 and the second connecting part 132 are detachably connected, and the air chamber communication structure 13 can switch between the first state and the second state.

[0080] 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 first air chamber 122 and the second air chamber 111 are in communication. In the second state, the first connecting portion 131 is detached from the second connecting portion 132, and the first air chamber 122 and the second air chamber 111 are not in communication. When the first air chamber 122 and the second air chamber 111 need to be connected, the air chamber communication structure 13 can be switched to the first state simply by pressing the first connecting portion 131 into the second connecting portion 132.

[0081] 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 structure 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, etc. The embodiments provided in this application do not limit this.

[0082] 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 structure 13 cannot be switched from the first state to the second state.

[0083] 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.

[0084] By adopting the above technical solution, and by setting a first connecting part 131 that is fluidly connected to the first air chamber 122 and a second connecting part 132 that is fluidly connected to the second air chamber 111, a modular design can be achieved. That is, the first connecting part 131 and the first air chamber 122 are one module, and the second air chamber 111 and the second connecting part 132 are another module. Even if either module is damaged, only the corresponding module needs to be replaced, which can reduce the probability of scrapping the entire product and has significant benefits in terms of environmental protection and production cost control. 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, and the first air chamber 122 and the second air chamber 111 are connected. The user only needs to perform one inflation and deflation operation to inflate and deflate the two air chambers, which is simple to operate and has high efficiency.

[0085] In some embodiments, see Figure 5 , Figure 6 , Figure 7The 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 second air chamber 111. The first connecting portion 131 includes a first hole wall 1312, and the second connecting portion 132 includes a second hole wall 1322. The first through hole 1311 is located within the first hole wall 1312, that is, the first through hole 1311 is an internal channel of the first hole wall 1312. The outer surface of the first hole wall 1312 abuts against the inner surface of the second hole wall 1322 of the second through hole 1321, and the first air chamber 122 and the second air chamber 111 are connected through the first through hole 1311.

[0086] In some embodiments, see Figure 7 , Figure 8 , Figure 9 Along the first direction X, the first connecting portion 131 includes a first end 1313 and a second end 1314. The first end 1313 is used to connect with the first outer wall, and the second end 1314 is provided with a snap-fit ​​protrusion 1315 protruding along the second direction Y. Along the first direction X, the second connecting portion 132 includes a third end 1323 and a fourth end 1324. The fourth end 1324 is located in the second air chamber 111. The third end 1323 is used to connect with the second outer wall, and the fourth end 1324 is provided with a snap-fit ​​recess 1325 recessed along the second direction Y. In the first state, the snap-fit ​​protrusion 1315 abuts against the snap-fit ​​recess 1325.

[0087] like Figure 10 As shown, taking the air nozzle 112 located in the first air chamber 122 as an example, during inflation, gas (e.g., air) enters the first air chamber 122 through the air nozzle 112, then flows along arrow a through the first through hole 1311 into the second air chamber 111. This allows one air chamber (e.g., the first air chamber 122) to be inflated, while the other air chamber (e.g., the second air 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 second air chamber 111 along arrow b through the first through hole 1311 into the first air chamber 122, eventually being released into the atmosphere.

[0088] For example, see Figure 7 , Figure 8 , Figure 9 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.

[0089] For example, see Figure 8 , Figure 9 , Figure 10 In the first state, along the first direction X, the first hole 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 less than or approximately equal to the height h2 between the fourth end 1324 and the third end 1323. The second end 1314 of the first hole wall 1312 and the fourth end 1324 of the second hole 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 preventing the first hole wall 1312 from protruding from the second through hole 1321 and damaging the sheet material of the second air chamber 111. 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.

[0090] Exemplarily, both the second end 1314 and the third end 1323 include chamfers. Exemplarily, the chamfer of the third end 1323 is formed by a first inclined surface 13231, and the chamfer of the second end 1314 is formed by a second inclined surface 13141. When the first connecting part 131 is inserted into the second connecting part 132, the first inclined surface 13231 and the second inclined surface 13141 contact each other, providing a guiding force for the first hole wall 1312 to enter the second through hole 1321. This facilitates the rapid assembly of the first connecting part 131 and the second connecting part 132 by external force pressing, reduces the risk of damaging the second hole wall 1322, and makes the connection process of the first connecting part 131 and the second connecting part 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.

[0091] In some embodiments, see Figure 8 , Figure 9 , Figure 10The first connecting portion 131 includes a first extension 1316, which is located at the first end 1313 and is attached to the first outer wall of the first air chamber 122 (e.g., the second piece 1202). The second connecting portion 132 includes a second extension 1326, which is located at the third end 1323 and is attached to the second outer wall of the second air chamber 111 (e.g., the third piece 1101). The first extension 1316 is an annular shape surrounding the first hole wall 1312, and the second extension 1326 is an annular shape surrounding the second hole wall 1322. The first through hole 1311 and the second through hole 1321 are both cylindrical. This application embodiment does not limit the shape of the first through hole 1311, the second through hole 1321, the first extension 1316, and the second extension 1326. For example, the first through hole 1311 and the second through hole 1321 can also be cylindrical.

[0092] For example, the first extension 1316 and the first end 1313 are rounded, and the second extension 1326 and the third end 1323 are rounded. In this way, there are no sharp edges on the outer sides of the first connecting portion 131 and the second connecting portion 132. By rounding the edges, damage to the second inflation gas 11 and the first inflation gas 12 can be avoided.

[0093] In some embodiments, see Figure 10 , Figure 11 A sealing structure is provided between the first hole wall 1312 and the second hole wall 1322. Exemplarily, the sealing structure includes a sealing ring 13122. The first hole 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 hole wall 1322; or, the second hole 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 hole wall 1322 and against the outer surface of the first hole wall 1312. Exemplarily, the first hole 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.

[0094] This application does not limit the type of sealing structure; for example, see the following: Figure 12 , Figure 13The sealing structure includes ribs 13123. Exemplarily, the first hole wall 1312 is provided with two ribs 13123, and the first hole wall 1312 does not have a sealing groove 13121. In a first state, the ribs 13123 are located on the inner side of the second hole wall 1322 and abut against the outer side of the first hole wall 1312; alternatively, the ribs 13123 are located on the outer side of the first hole wall 1312 and abut against the inner side of the second hole 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 hole wall 1312 are integrally formed, but this application does not limit this; the ribs 13123 and the first hole wall 1312 can also be two independent components.

[0095] In some embodiments, see Figure 14 , Figure 15 and in conjunction with the appendix Figure 2 Along the first direction X, a second gas filling gas 11 is stacked above a first gas filling gas 12, and the second gas filling gas 11 and the first gas filling gas 12 are detachably connected. Exemplarily, the second piece 1202 of the first gas filling gas 12 contacts the third piece 1101 of the second gas filling gas 11, and the second gas filling gas 11 and the first gas filling gas 12 are detachably connected only through a gas chamber communication structure 13, not through a connecting piece 123 (e.g., ...). Figure 3 (As shown). By adopting the above technical solution, the second inflation gas 11 can rotate relative to the first 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 second inflation gas 11 is one module and the first inflation gas 12 is another module.

[0096] In some embodiments, the second gas 11 and the first gas 12 may be further connected to enhance their stability. For example, see [link to relevant documentation]. Figure 14 , Figure 15 The car mattress also includes a connecting piece 123, which is connected to the first inflation piece 12 and the second inflation piece 11. One side of the connecting piece 123 is located at the junction of the second piece 1202 and the side piece 1203, and the connecting piece 123 is located on the long side (parallel to the second direction Y) of the second inflation piece 11. The other side of the connecting piece 123 is connected to the fourth piece 1102.

[0097] Understandably, the connecting piece 123 can also be located on the short side (parallel to the third direction Z) of the second gas filling 11, or simultaneously on both the long and short sides of the second 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 first piece and a second piece, where one piece, such as the first piece, is connected to the second gas filling 11, and the other piece, such as the second piece, is connected to the first gas filling 12. The two pieces of the connecting piece 123 can be connected by welding or gluing to form a fixed connecting piece 123, or the two pieces of the connecting piece 123 can be connected by zippers, buttons, or Velcro to form a detachable connecting piece 123.

[0098] Furthermore, this application does not limit the connection method between the second filling gas 11 and the first filling gas 12. For example, see [reference needed]. Figure 14 , Figure 15 and in conjunction with the appendix Figure 2 The fourth piece 1102 (i.e., the surface piece of the second gas-filled 11) is connected to the second piece 1202 (i.e., the surface piece of the first gas-filled 12) via a connecting piece 123, or the fourth piece 1102 is connected to the side piece 1203 of the first gas-filled 12 via a connecting piece 123. Exemplarily, the third piece 1101 (i.e., the bottom piece of the second gas-filled 11) is connected to the second piece 1202 via a connecting piece 123, or the third piece 1101 is connected to the side piece 1203 via a connecting piece 123.

[0099] Understandably, the connection method between the second gas filling 11 and the first gas filling 12 is not limited to this. For example, the third piece 1101 can be connected to both the second piece 1202 and the side piece 1203 via a connecting piece 123, and the fourth piece 1102 can be connected to both the second piece 1202 and the side piece 1203 via a connecting piece 123. Understandably, 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 second gas filling 11 and the first gas filling 12 to achieve a detachable connection.

[0100] In some embodiments, see Figure 14 , Figure 15 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.

[0101] For example, on the first piece 1201, along the second direction Y, a first protrusion 1211 and a second protrusion 1212 are adjacent, 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.

[0102] In some embodiments, see Figure 14 , Figure 15 and in conjunction with the appendix Figure 2 Along the second direction Y, the first air 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.

[0103] 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 first piece 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.

[0104] For example, on the first piece 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.

[0105] In some embodiments, see Figure 14 , Figure 15 and in conjunction with the appendix Figure 2 The first inflation 12 includes an arcuate portion 12221, where the width of the first piece 1201 narrows. 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 a flat position, 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 first inflation 12 according to the shape of the seat 20.

[0106] In some embodiments, see Figure 14 , Figure 15 and in conjunction with the appendix Figure 2 The first gas filling 12 includes several sets of tensioning members, which are located in the first gas chamber 122 and connected to the first piece 1201 and the second piece 1202. The several sets of tensioning members have different heights.

[0107] 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 first piece 1201 and the second piece 1202. Exemplarily, each tensioning member is connected to the first piece 1201 and the second piece 1202 by high-frequency welding, hot melting, adhesive bonding, or other connection methods. After being tensioned, the tensioning members provide tension to the first piece 1201 and the second piece 1202 to limit the deformation of the second inflatable 11, so that the second inflatable 11 can maintain a preset shape after being inflated, such as maintaining a convex or concave state.

[0108] 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.

[0109] Sheet-shaped tensioning components can have single-layer or composite-layer structures depending on actual needs.

[0110] 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).

[0111] 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.

[0112] The linear tensioning member comprises one or more threads that span the distance between the first piece 1201 and the second piece 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 first piece 1201 and the second piece 1202 via a connector, which may be made of a polymeric material, but is not limited to, materials that facilitate welding the first piece 1201 and the second piece 1202.

[0113] In some embodiments, see Figure 14 , Figure 15 , Figure 16 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.

[0114] 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] Figure 14 , Figure 15 , Figure 16 and in conjunction with the appendix Figure 2 Along the second direction Y, the height of the plurality of first tensioning members 1241 from the middle position toward 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.

[0115] In some embodiments, see Figure 14 , Figure 15 , Figure 16 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.

[0116] 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.

[0117] In some embodiments, see Figure 14 , Figure 15 , Figure 16 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.

[0118] In some embodiments, see Figure 14 , Figure 15 , Figure 16 and in conjunction with the appendix Figure 2 Along the second direction Y, the height of the plurality of third tensioning members 1261 facing one end of the third region 1223 toward 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 facing one end of the third region 1223 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.

[0119] 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.

[0120] In some embodiments, see Figure 14 , Figure 15 , Figure 16 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 first piece 1201, and the second side 128 is connected to the second piece 1202.

[0121] 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 128 near the second gas 11 and a shorter first side 127 away from the second gas 11, and their projections along the second direction Y are all trapezoidal, which can better support the second gas 11. Specifically, the second tensioning members 1251 in the second group of tensioning members 125 are all trapezoidal, and the width of the first piece 1201 is narrowed at the second region 1222 to fit the second group of tensioning members 125, thereby forming an arc portion 12221.

[0122] 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 16 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.

[0123] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. 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.
