[0055] To make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0056] Figure 1 The inflatable vehicle-mounted mattress 1 (hereinafter referred to as the vehicle-mounted mattress 1) according to one embodiment of the present application is schematically shown. The vehicle-mounted mattress 1 includes a mattress portion 2 and a support portion 3 connected to the mattress portion 2. Figure 3a and Figure 3b As shown, the mattress portion 2 includes a first wall 21 defining a first air-filled cavity 203. A first gas control device 22 ( Figure 3a and Figure 3bThe first gas control device 22 is connected to the first gas-filled cavity 203 to inflate or deflate the first gas-filled cavity 203. The support portion 3 includes a second wall 31 defining a second gas-filled cavity 303. The second gas-filled cavity 303 is separated from the first gas-filled cavity 203 by a partition wall 313. A second gas control device 32 is provided on the second wall 31, and the second gas control device 32 is connected to the second gas-filled cavity 303 to inflate or deflate the second gas-filled cavity 303.

[0057] After the pressure of the gas (e.g., air) in the first inflation cavity 203 reaches a desired value, the mattress portion 2 is in an inflated state and maintains a preset shape; and when the gas in the first inflation cavity 203 is exhausted, the mattress portion 2 is in a deflated state. The same is true for the support portion 3. The volume of the vehicle-mounted mattress 1 in the deflated state is greatly reduced relative to the volume when it is in the inflated state, thereby facilitating the storage of the vehicle-mounted mattress 1.

[0058] like Figure 1 As shown, when the mattress portion 2 and the support portion 3 are inflated, the support portion 3 is substantially perpendicular to the mattress portion 2 to support the mattress portion 2 in a vertical direction substantially perpendicular to the mattress portion 2. When the inflated vehicle mattress 1 is placed in a vehicle, the support portion 3 is supported on the floor between the front seat and the rear seat, and a portion of the mattress portion 2 is supported on the rear seat. Thus, the vehicle mattress 1 is stably placed in the vehicle.

[0059] In one embodiment, Figure 1 As shown, the mattress portion 2 is generally in the shape of a rectangular parallelepiped and includes a first edge 201 and a second edge 202 that are parallel to each other (for example, the first edge 201 and the second edge 202 are two long sides of the mattress portion 2). The support portion 3 is configured to extend along the longitudinal direction of the mattress portion 2 (i.e., the length direction of the mattress portion) (i.e., the support portion 3 generally extends along the extension direction of the first edge 201). The distance between the support portion 3 and the first edge 201 is greater than the distance between the support portion 3 and the second edge 202. In other words, the support portion 3 is located on the side of the line connecting the midpoints of the two short sides of the mattress portion 2 close to the second edge 202. When the inflated vehicle mattress 1 is placed in a vehicle, the second edge 202 can be pressed against the backrest of the front seat, and the first edge 201 can be pressed against the backrest of the rear seat. In this way, the front seat and the rear seat limit the vehicle mattress 1, preventing the vehicle mattress 1 from moving in the vehicle, which helps to improve the user experience of the vehicle mattress 1. It should be understood that the length of the vehicle-mounted mattress 1 only needs to match the width of the vehicle, and there is no specific limitation.

[0060] In one embodiment, the vehicle-mounted mattress 1 may further include auxiliary components such as an inflatable pillow, and a concave-convex shape may be constructed on the vehicle-mounted mattress 1 to improve the comfort of the vehicle-mounted mattress 1 .

[0061] The vehicle-mounted mattress 1 also includes a one-way valve 4. Figure 3a As shown, there are two one-way valves 4 installed on the partition wall 313. Each one-way valve 4 is configured to allow the gas in the second gas-filled cavity 303 to flow into the first gas-filled cavity 203, while preventing the gas in the first gas-filled cavity 203 from flowing into the second gas-filled cavity 303. It should be noted that in the present application, the number of one-way valves 4 installed on the partition wall 313 is not limited, and for example, 1, 2, 3, 4 or 5 one-way valves 4 may be provided.

[0062] When using the vehicle-mounted mattress 1 of the present application, the second inflation chamber 303 can be inflated through the second gas control device 32 on the support part 3. The one-way valve 4 allows the gas in the second inflation chamber 303 to flow into the first inflation chamber 203. In this way, the entire vehicle-mounted mattress 1 is inflated (that is, both the mattress part 2 and the support part 3 can be inflated). During the inflation process, there is no need to use multiple air pumps to inflate the first inflation chamber 203 and the second inflation chamber 303 independently, which facilitates the user's operation. Of course, it is also possible to inflate the first inflation chamber 203 through the first gas control device 22 according to actual conditions, and at the same time inflate the second inflation chamber 303 through the second gas control device 32 to improve the inflation efficiency of the vehicle-mounted mattress 1.

[0063] Users of vehicle-mounted mattresses often have the need to use inflatable mattresses in spaces outside the vehicle (for example, at home, outdoors), and often hope that the vehicle-mounted mattress can be compatible with other occasions at the same time, but other occasions often do not have the environmental structure of the vehicle. For example, in order to use the vehicle-mounted mattress 1 on a flat ground (or other flat environment) (that is, only using the mattress part 2), the first inflation chamber 203 can also be inflated through the first gas control device 22, but the second inflation chamber 303 is not inflated through the second gas control device 32. The gas in the first inflation chamber 203 cannot flow into the second inflation chamber 303 through the one-way valve 4. As a result, the mattress part 2 is in an inflated state, the second inflation chamber 303 cannot be inflated, and the support part 3 is in a deflated state and does not support the mattress part 2 (such as Figure 2 As shown). In this way, the vehicle-mounted mattress 1 can be used on a flat ground. In addition, when both the mattress part 2 and the support part 3 are inflated, the second gas control device 32 can be used to deflate the second inflation chamber 303, so that the support part 3 is in a deflated state. The one-way valve 4 prevents the gas in the first inflation chamber 203 from flowing into the second inflation chamber 303, so that the mattress part 2 remains inflated. In this way, the vehicle-mounted mattress 1 can also be used on a flat ground.

[0064] When the vehicle-mounted mattress 1 is folded, the first air chamber 203 can be deflated by the first air control device 22, and the second air chamber 303 can be deflated by the second air control device 32. Thus, both the mattress portion 2 and the support portion 3 are in a deflated state, so that the vehicle-mounted mattress 1 can be folded.

[0065] like Figure 5 As shown, the one-way valve 4 includes a mounting plate 41 and a flexible valve plate 42. Specifically, as Figure 7 and Figure 8 As shown, the mounting plate 41 includes a main body 411, and an assembly hole 412 and a vent hole 413 are configured on the main body 411. For example, the number of the assembly hole 412 is one and is arranged at the center of the main body 411, and the number of the vent holes 413 is multiple and is arranged around the assembly hole 412.

[0066] In addition, the main body 411 further has a first end surface 414 and a second end surface 415 opposite to the first end surface 414. The mounting plate 41 is mounted on the partition wall 313 and the first end surface 414 of the main body 411 faces the first plenum cavity 203 and the second end surface 415 of the main body 411 faces the second plenum cavity 303.

[0067] The valve plate 42 may be made of, for example, silicone rubber. Fig. 9 As shown, the valve plate 42 includes a blocking plate 421 and a mounting post 422 connected to the blocking plate 421. The mounting post 422 is adapted to be fixedly mounted in the assembly hole 412, and the blocking plate 421 is adapted to be attached to the first end surface 414 to block the vent hole 413, or to be separated from the first end surface 414 to allow the vent hole 413 to be open.

[0068] According to this one-way valve 4, before the vehicle-mounted mattress 1 is inflated, the air pressure in the second inflatable cavity 303 of the support part 3 is equal to the air pressure in the first inflatable cavity 203 of the mattress part 2, and the blocking sheet 421 is tightly attached to the first end surface 414 and blocks the vent 413. When the second inflatable cavity 303 is inflated, the air pressure in the second inflatable cavity 303 gradually increases. When the air pressure difference between the second inflatable cavity 303 and the first inflatable cavity 203 is large enough, the blocking sheet 421 will be pushed away from the first end surface 414 by the gas in the second inflatable cavity 303 to open the vent 413, and the gas in the second inflatable cavity 303 will flow into the first inflatable cavity 203 through the vent 413 to inflate the mattress part 2. Finally, both the support part 3 and the mattress part 2 are inflated. After the vehicle-mounted mattress 1 is inflated, the air pressure in the second inflation cavity 303 is equal to the air pressure in the first inflation cavity 203 , and the blocking sheet 421 returns to being in close contact with the first end surface 414 and blocks the vent hole 413 .

[0069] If the mattress part 2 accidentally leaks slightly, the air pressure in the second air chamber 303 will be greater than the air pressure in the first air chamber 203 again. The blocking sheet 421 will leave the first end surface 414 again to open the vent hole 413, so that the gas in the second air chamber 303 will flow into the first air chamber 203 to replenish the air in the mattress part 2. For example, when a person's body accidentally touches the first air control device 22 (for example, it can be the first air plug described below), so that the first air control device 22 is in an open state, the mattress part 2 will continue to leak, resulting in the air pressure in the second air chamber 303 being higher than the air pressure in the first air chamber 203, so that the gas in the second air chamber 303 flows into the first air chamber 203 through the one-way valve 4 to continuously replenish the air in the mattress part 2. When the air leakage of the mattress part 2 is discovered in time and the first gas control device 22 is closed, the air pressure in the second air chamber 303 gradually reaches a balance with the air pressure in the first air chamber 203, and the one-way valve 4 will return to the closed state, and the gas in the second air chamber 303 will no longer flow into the first air chamber 203.

[0070] When only the mattress part 2 is inflated, the air pressure in the first inflation cavity 203 is greater than the air pressure in the second inflation cavity 303, so that the blocking sheet 421 is kept in close contact with the first end surface 414 and blocks the vent 413. Thus, the air is prevented from flowing from the first inflation cavity 203 into the second inflation cavity 303, so that the support part 3 is in a deflated state, while the mattress part 2 is in an inflated state.

[0071] When both the support part 3 and the mattress part 2 are inflated, when the support part 3 is deflated, the air pressure in the second inflation chamber 303 will decrease and be lower than the air pressure in the first inflation chamber 203. The blocking sheet 421 will be pressed tightly against the first end surface 414 by the air in the first inflation chamber 203 and keep blocking the vent 413 to prevent the air from flowing from the first inflation chamber 203 into the second inflation chamber 303. In this way, the support part 3 is finally in a deflated state, while the mattress part 2 is in an inflated state.

[0072] Preferably, the blocking sheet 421 is circular, and the diameter of the blocking sheet 421 is between 10.0 mm and 36.0 mm, and more preferably, the diameter of the blocking sheet 421 is between 13.0 mm and 23.0 mm. For example, the blocking sheet 421 can be circular with a diameter of 10.0 mm, 13.0 mm, 18.0 mm, 23.0 mm or 36.0 mm. Preferably, the vent hole 413 can also be circular, and the diameter of the vent hole 413 is between 1.0 mm and 7.0 mm, and more preferably, the diameter of the vent hole 413 is between 2.0 mm and 5.0 mm. For example, the diameter of the vent hole 413 is 1.0 mm, 2.0 mm, 3.5 mm, 5.0 mm or 7.0 mm.

[0073] When the diameter of the blocking sheet 421 is a certain value, the larger the diameter of the vent hole 413, the easier it is for the gas to pass through the one-way valve 4 quickly, but the one-way valve 4 is relatively easy to leak. The smaller the diameter of the vent hole 413, the better the air tightness of the one-way valve 4, but the speed of the airflow passing through the one-way valve 4 is relatively slow.

[0074] In addition, when the ratio of the area of ​​the blocking sheet 421 to the total area of ​​the vent 413 is smaller, the total area of ​​the vent 413 accounts for a larger proportion in the total area of ​​the main body 411 of the mounting plate 41, and the gas is more likely to pass through the one-way valve 4 quickly, but the one-way valve 4 is relatively easy to leak; when the ratio of the area of ​​the blocking sheet 421 to the total area of ​​the vent 413 is larger, the total area of ​​the vent 413 accounts for a smaller proportion in the total area of ​​the main body 411 of the mounting plate 41, and the one-way valve 4 has better air tightness, but the air flow speed is relatively slow. For this reason, the blocking sheet 421 is set to a ratio of the area of ​​the blocking sheet 421 to the total area of ​​the vent 413 between 2.3 and 54. For example, the diameter of the blocking sheet 421 can be between 10 mm and 36 mm. The number of vents 413 is 6, and the diameter of each vent 413 is between 1 mm and 7 mm. In this way, it is ensured that the gas can pass through the one-way valve 4 easily and quickly, and the air tightness of the one-way valve 4 is also ensured. Preferably, when the diameter of the blocking sheet 421 is 18.0 mm and the number of the vent holes 413 is 6, it is calculated that the area of ​​the blocking sheet 421 is 254.5 mm 2 At this time, the diameter of the vent hole 413 can be 1.0 mm, 2.8 mm, 3.5 mm, 4.1 mm or 4.8 mm. According to calculation, the corresponding total area of ​​the vent holes is 4.7 mm 2 、36.9mm 2 、57.7mm 2 、79.2mm 2 and 108.6mm 2 Furthermore, by dividing the area of ​​the blocking sheet 421 by the total area of ​​the vent holes 413 , it can be obtained that the ratio of the area of ​​the blocking sheet 421 to the total area of ​​the vent holes 413 is 54, 6.9, 4.4, 3.2 or 2.3 respectively.

[0075] In one embodiment, preferably, the thickness of the barrier sheet 421 is between 0.3 mm and 1.2 mm, and more preferably, the thickness of the barrier sheet 421 is between 0.35 mm and 0.7 mm. For example, the thickness of the barrier sheet 421 may be 0.3 mm, 0.35 mm, 0.4 mm, 0.7 mm, or 1.2 mm. In this way, the thickness of the barrier sheet 421 is small to improve the flexibility of the barrier sheet 421.

[0076] like Figure 6 and Fig. 9As shown, the mounting post 422 is configured with a convex shoulder 423, which protrudes outward from the circumferential surface of the mounting post 422. When the valve plate 42 is mounted on the mounting plate 41, the convex shoulder 423 is contracted and deformed to pass through the assembly hole 412. After passing through the assembly hole 412, the convex shoulder 423 automatically expands and abuts against the second end surface 415 of the main body 411 of the mounting plate 41. In this way, the valve plate 42 is fixedly mounted on the mounting plate 41.

[0077] Also like Figure 7 As shown, a boss 416 surrounding the assembly hole 412 is constructed on the second end surface 415 of the main body 411 of the mounting plate 41. When the valve plate 42 is mounted on the mounting plate 41, the boss 423 engages with the boss 416 (for example, the boss 423 abuts against the end surface of the boss 416). In this way, after the valve plate 42 is mounted on the mounting plate 41, the mounting column 422 is slightly elongated, so that the blocking sheet 421 fits tightly on the first end surface 414 of the main body 411 of the mounting plate 41. In this way, when the air pressure in the second inflatable cavity 303 is lower than the air pressure in the first inflatable cavity 203 (for example, when the mattress part 2 is inflated and the support part 3 is in deflated), the blocking sheet 421 is not easy to separate from the first end surface 414, so that the gas in the first inflatable cavity 203 can hardly flow into the second inflatable cavity 303 through the vent 413.

[0078] Also like Figure 7 and Figure 8 As shown, the mounting plate 41 further includes a flange 417 surrounding the main body 411 and connected to the main body 411. For example, the flange 417 is located radially outside the main body 411. The flange 417 is adapted to be fixedly connected to the partition wall 313 so as to fix the one-way valve 4 on the partition wall 313. The flange 417 is spaced apart from the vent hole 413 along the radial direction of the mounting plate 41. In this way, when the flange 417 is connected to the partition wall 313, it is not easy to cause the vent hole 413 to be blocked, and it is not easy to cause the one-way valve 4 to fail. Preferably, the flange 417 is in a circular ring shape, and the outer diameter of the flange 417 is between 20.0 mm and 60.0 mm, and more preferably, the outer diameter of the flange 417 is between 25.0 mm and 35.0 mm. For example, the outer diameter of the flange 417 can be 20.0 mm, 25.0 mm, 30.0 mm, 35.0 mm or 60.0 mm.

[0079] In one embodiment, the mounting plate 41 includes a cylindrical connecting portion 418. The connecting portion 418 has a first end and a second end axially opposite to the first end. The first end of the connecting portion 418 is connected to the second end surface 415, and the flange 417 is connected to the second end of the connecting portion 418. For example, the connecting portion 418 is connected to the circumferential edge of the second end surface 415 and is substantially perpendicular to the main body 411 and the flange 417. In this way, the main body 411 and the flange 417 are on different planes, and when the flange 417 is connected to the partition wall 313, the vent hole 413 can be prevented from being blocked. Preferably, the height of the connecting portion 418 is between 4.0 mm and 15.0 mm, and more preferably, the height of the connecting portion 418 is between 5.0 mm and 10.0 mm. For example, the height of the connecting portion 418 can be 4.0 mm, 5.0 mm, 6.0 mm, 10.0 mm or 15.0 mm.

[0080] In one embodiment, the partition wall 313 is made of a plastic film, and the mounting plate 41 is also made of plastic. In this way, the flange 417 can be welded to the partition wall 313. In one embodiment, the partition wall 313 can be made of a PVC (i.e., polyvinyl chloride) film or a TPU (i.e., thermoplastic polyurethane) film, so that the partition wall 313 has good flexibility, so as to facilitate the storage of the vehicle-mounted mattress 1.

[0081] In one embodiment, Figure 1 As shown, the first gas control device 22 is a first air plug. The first air plug can deflate the mattress portion 2. In one embodiment, an external air pump (not shown) can also be used to connect to the first air plug to inflate the mattress portion 2.

[0082] In one embodiment, the first gas control device 22 may also be a first built-in air pump (not shown) mounted on the first wall 21. In this way, the first built-in air pump can be used to inflate or deflate the mattress portion 2 without providing a first air plug on the mattress portion 2. When the vehicle-mounted mattress 1 is used or folded, the first built-in air pump does not need to be removed from the mattress portion 2. Of course, if the first built-in air pump can only inflate the mattress portion 2 but cannot deflate the mattress portion 2, then the first air plug needs to be provided on the mattress portion 2.

[0083] In one embodiment, Figure 1 As shown, the second gas control device 32 includes a second built-in air pump 321 and a second air plug 322. When the vehicle-mounted mattress 1 is used or folded, the second built-in air pump 321 does not need to be removed from the support portion 3. The second built-in air pump 321 is used to inflate the support portion 3 (or the vehicle-mounted mattress 1), so that the user does not need to configure an additional air pump for the vehicle-mounted mattress 1, which avoids the inconvenience caused to the user by carrying an air pump. The second air plug 322 can be used to deflate the support portion 3.

[0084] In one embodiment, the second built-in air pump 321 can also be used to deflate the support portion 3. In this case, there is no need to provide a second air plug on the support portion 3.

[0085] In one embodiment, Figure 4 As shown, only the second air plug 322 is provided on the support part 3, but no second built-in air pump is provided. In this case, an external air pump (not shown) needs to be connected to the second air plug 322 to inflate the support part 3 (or the vehicle-mounted mattress 1).

[0086] like Figure 3a and Figure 3b As shown, the first wall 21 of the mattress portion 2 includes a top sheet 211 and a bottom sheet 212. The edges of the top sheet 211 and the bottom sheet 212 are connected together (e.g., welded together) and define the first inflation chamber 203. The first gas control device 22 is mounted on the top sheet 211 or the bottom sheet 212. The partition wall 313 is formed as at least a part of the bottom sheet 212 of the mattress portion 2. In this way, the one-way valve 4 is also mounted on the bottom sheet 212 of the mattress portion 2.

[0087] The support portion 3 has a mounting end 315 facing the bottom sheet 212 of the mattress portion 2. An opening 314 communicating with the second inflatable chamber 303 is configured at the mounting end 315. The mounting end 315 of the support portion 3 is connected to the bottom sheet 212 of the mattress portion 2 (for example, welded together), and the one-way valve 4 is within the range of the opening 314. In this way, the one-way valve 4 can control the gas flow between the first inflatable chamber 203 and the second inflatable chamber 303.

[0088] In one embodiment, Figure 3a As shown, the bottom sheet 212 of the mattress part 2 is made of a plastic film (e.g., a PVC film or a TPU film), or made of a PVC mesh material or a TPU mesh material. A mounting hole 213 is provided on the bottom sheet 212, and the one-way valve 4 is installed in the mounting hole 213. According to this structure, the partition wall 313 is integral with the bottom sheet 212. The mounting end 315 of the support part 3 is welded to the bottom sheet 212, and the one-way valve 4 is within the range of the opening 314 at the mounting end 315 of the support part 3. The above-mentioned "mesh material" refers to a three-layer material formed by bonding two polymer sheets (such as PVC film or TPU film) and a mesh cloth sandwiched therebetween.

[0089] In another embodiment, Figure 3bAs shown, the bottom sheet 212 of the mattress part 2 includes a first part 214 made of a PVC cloth patch or a TPU cloth patch and a partition wall 313 made of a plastic film (e.g., a PVC film or a TPU film), and the shape of the partition wall 313 is substantially the same as the shape of the mounting end 315 of the support part 3. The partition wall 313 is connected to the first part 214. For example, an interface substantially the same in shape as the partition wall 313 is provided on the first part 214, and the partition wall 313 is welded at the interface to form a circumferentially closed first weld 215. According to this structure, the partition wall 313 is a part of the bottom sheet 212. The mounting hole 213 is provided on the partition wall 313, and the one-way valve 4 is installed in the mounting hole 213. In this case, the mounting end 315 of the support part 3 is welded to the partition wall 313 to form a circumferentially closed second weld 216, and the second weld 216 is located on the inner side of the first weld 215. In addition, the one-way valve 4 is located inside the second weld 216, so that the one-way valve 4 is also located within the range of the opening 314 at the mounting end 315 of the support part 3. The "cloth patch" refers to a double-layer material formed by bonding a fabric or non-woven fabric and a polymer sheet (such as a PVC film or a TPU film) to each other. It should be understood that the surface sheet 211 of the mattress part 2 can also be a PVC cloth patch or a TPU cloth patch to improve the user's experience.

[0090] In one embodiment, Figure 3b As shown, the second wall 31 of the support portion 3 includes a first side piece 311, a second side piece 312 and a surrounding piece 316. For example, the first side piece 311 and the second side piece 312 are generally rectangular and each has two long edges and two short edges. The surrounding piece 316 can be a whole piece formed in one piece, for example, the surrounding piece 316 is generally strip-shaped and has two long edges and two short edges in an unfolded state when not welded. The first side piece 311 and the second side piece 312 are generally parallel and oppositely arranged and spaced apart. One long edge of the surrounding piece 316 is connected to two width edges and one length of the first side piece 31, and the other long edge of the surrounding piece 316 is connected to two width edges and one length of the second side piece 312. Thus, the first side panel 311, the second side panel 312 and the surrounding panel 316 together define the second inflation cavity 303, and the other long edge of the first side panel 311, the other long edge of the second side panel 312 and the two short edges of the surrounding panel 316 together define the opening 314 at the mounting end 315 of the support portion 3.

[0091] In addition, the surrounding piece 316 can also be formed by splicing three sides, that is, the surrounding piece 316 includes two vertical surfaces and a bottom surface, and each vertical surface includes two long edges and two short edges. The bottom surface includes two long edges and two short edges. The two long edges of each vertical surface are respectively connected to the short edges of the first side piece 311 and the second side piece 312. The bottom surface is at the bottom of the support portion 3, and the two long edges of the bottom surface are respectively connected to the corresponding long edges of the first side piece 311 and the second side piece 312, and the two short edges of the bottom surface are respectively connected to the corresponding short edges of the two vertical surfaces to define the second inflatable cavity 303. The other short edges of the two vertical surfaces, together with the other long edge of the first side piece 311 and the other long edge of the second side piece 312, define the opening 314 at the mounting end 315 of the support portion 3. It should be understood that the support portion 3 may also have other structures, but have an opening at the mounting end of the support portion 3.

[0092] A plurality of tensioning members (not shown) are arranged in the first inflation cavity 203 of the mattress part 2, and the tensioning members are connected to the top sheet and the bottom sheet by high-frequency welding, hot melting, gluing or other connection methods. After being tensioned, the tensioning members provide tension to the top sheet and the bottom sheet to limit the deformation of the mattress part, so that the mattress part can maintain a preset shape after being inflated. The same is true for the support part. For example, Figure 3b As shown, a plurality of tension members 302 are arranged in the second inflation chamber 303 of the support portion 3. The tension members 302 are connected between the first side panel 311 and the second side panel 312.

[0093] Optionally, the plurality of tension members have different structures in different embodiments. For example, each tension member is a sheet-like tension member or a linear tension member.

[0094] The sheet-like tension member may have a single-layer structure or a composite-layer structure according to actual needs.

[0095] When the sheet-like tension member is a single-layer sheet material, it can be made of a polymer material, and the polymer material can include but is not limited to one or more of polyvinyl chloride (PVC), polyurethane (PU), thermoplastic polyurethanes (TPU), polyethyleneterephthalate (PET), ethylene-vinyl acetate (EVA) copolymer and nylon. It can be understood that the main body of the single-layer sheet-like tension member can also be made of other materials other than polymer materials in other embodiments, such as a fabric material, wherein the fabric material can be finely woven or formed into a mesh structure. The fabric material can be but is not limited to a natural fiber fabric (for example, but not limited to, cotton fabric, linen fabric, wool fabric, silk fabric) or a synthetic fiber fabric (for example, but not limited to, polyester fiber fabric, polyethylene fiber fabric, polypropylene fiber fabric).

[0096] When the sheet-like tension member is a composite sheet, it is composed of two or more layers of sheets bonded together by gluing, welding or other means, and each layer of the multi-layer sheet can be made of the polymer material or other materials as described above.

[0097] The linear tension member includes one or more threads. The one or more threads are optionally parallel or substantially parallel in space, for example, the threads are spaced from each other at equal distances or in a manner that varies according to a certain rule. The material of the one or more threads in the linear tension member can be, but is not limited to, natural fibers (for example, but not limited to, cotton fibers, linen fibers, wool fibers, silk fibers) or synthetic fibers (for example, but not limited to, polyester fibers, polyethylene fibers, polypropylene fibers).

[0098] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
