Technical Field

[0001] This utility model relates to the field of inflatable products, and in particular to a vehicle-mounted inflatable bed. Background Technology

[0002] Inflatable products, due to their light weight and ease of packaging and storage, have been widely used in people's leisure and entertainment. For example, an inflatable bed is an inflatable product for people to sit or lie on for leisure and entertainment.

[0003] However, most inflatable mattresses on the market are flat, while the interior of a car is uneven due to the presence of car seats and other internal components. Using an inflatable mattress in a car would result in instability and wobbling, posing a safety hazard when the user is sitting or lying down. Utility Model Content

[0004] The purpose of this invention is to solve the problem of shaking that occurs when inflatable mattresses are used in vehicles. This invention provides a vehicle-mounted inflatable mattress that effectively avoids shaking when used in a vehicle.

[0005] To solve the above-mentioned technical problems, this utility model discloses a vehicle-mounted inflatable mattress, comprising:

[0006] The main body of the air bed includes the main air-inflating chamber;

[0007] The first support body is located at the bottom of the air bed body and includes a first air chamber;

[0008] The second support body is located at the bottom of the air bed body and includes a second air chamber. Along the width direction, the second support body is spaced apart from the first support body.

[0009] The third support body is located at the bottom of the air bed body and includes a third air chamber. Along the length direction, the first support body and the second support body are located on the same side of the third support body, and the length direction is perpendicular to the width direction.

[0010] By adopting the above technical solution, when using the vehicle-mounted inflatable mattress, the first support body is placed above the driver's seat, the second support body is placed above the passenger seat, and the third support body is placed above the rear seats of the car. Thus, the first, second, and third support bodies together support the main body of the inflatable mattress in a horizontal or near-horizontal state for the user to rest in. Alternatively, the first, second, and third support bodies can be described as "filling" the surface, leveling any uneven areas inside the car (such as the seat cushions of the driver's seat, passenger seat, and rear seats), thereby ensuring that the tops of the first, second, and third support bodies are aligned. This, in turn, keeps the main body of the inflatable mattress in a horizontal or near-horizontal state, effectively preventing the vehicle-mounted inflatable mattress 100 from shaking during use, avoiding potential dangers, and providing a good user experience.

[0131] 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.

[0132] refer to Figures 1 to 4 In the description of this application, the gas-filled chamber includes at least one first wall 11, a second wall 12, and an inflation chamber 13 defined by the first wall 11 and the second wall 12. When the pressure of the gas (e.g., air) in the inflation chamber 13 reaches the required value, the gas-filled chamber is in an inflated state and maintains a preset shape. When the gas in the inflation chamber 13 is discharged, the gas-filled chamber is in a deflated state, and the volume of the gas-filled chamber is greatly reduced compared to when it is in an inflated state, thereby facilitating the storage of the gas-filled chamber.

[0133] A plurality of tensioning members 20 are provided in the gas-filled chamber 13. The tensioning members 20 are connected to the first wall 11 and the second wall 12 by high-frequency welding, hot melting, adhesive bonding or other connection methods. After being tensioned, the tensioning members 20 provide tension to the first wall 11 and the second wall 12 to limit the deformation of the gas, so that the gas can maintain a preset shape after being inflated.

[0134] Optionally, the plurality of tensioning members 20 may have different structures in different embodiments. For example, each tensioning member 20 may be a sheet-like tensioning member 21 or a wire-like tensioning member 22.

[0135] The sheet-like tensioning member 21 can have a single-layer or composite-layer structure depending on actual needs.

[0136] refer to Figure 1 When the sheet-like tensioning member 21 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 21 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).

[0137] refer to Figure 2 When the sheet-like tensioning member 21 is a composite sheet, it is composed of two or more layers of sheet material bonded together by adhesive, welding or other means. Each layer of the multilayer sheet material can be made of the polymer material as described above or other materials as described above.

[0138] refer to Figure 3 and Figure 4The linear tensioning member 22 comprises one or more threads that span the distance between the gas-filled first wall 11 and the second wall 12, 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 22 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 22 is typically indirectly connected to the first wall 11 and the second wall 12 via a connector, which may be made of a polymeric material, but is not limited to, materials that facilitate welding of the first wall 11 and the second wall 12.

[0139] refer to Figure 5a This application provides a vehicle-mounted inflatable mattress 100, including: an inflatable mattress body 200, a first support 300, a second support 400, and a third support 500. The first support 300, second support 400, and third support 500 are all located at the bottom of the inflatable mattress body 200. When the vehicle-mounted inflatable mattress 100 is in use, the first support 300, second support 400, and third support 500 are respectively supported by the structure inside the vehicle, thereby keeping the tops of the first support 300, second support 400, and third support 500 at the same or approximately the same horizontal plane, so that the inflatable mattress body 200 located above remains horizontal or approximately horizontal, thus providing a good user experience.

[0140] It should be noted that the reference Figure 5b In this embodiment, "approximately horizontal" means that the air mattress body 200 is slightly inclined relative to the horizontal plane a. For example, the angle β between the air mattress body 200 and the horizontal plane a is less than 10°. Preferably, the angle β between the air mattress body 200 and the horizontal plane a is less than 5°. More preferably, the angle β between the air mattress body 200 and the horizontal plane a is less than 2°.

[0141] To facilitate the description of the specific structure of the vehicle-mounted air mattress 100, this embodiment first defines the length direction X, width direction Y, and height direction Z of the vehicle-mounted air mattress 100, wherein the length direction X, width direction Y, and height direction Z are perpendicular to each other. When the vehicle-mounted air mattress 100 is in use, the length direction of the vehicle-mounted air mattress 100 is the same as the length direction of the car, both being the length direction X; the width direction of the vehicle-mounted air mattress 100 is the same as the width direction of the car, both being the width direction Y; and the height direction Z of the vehicle-mounted air mattress 100 is the same as the height direction Z of the car, both being the height direction Z.

[0142] It is understood that a car includes front seats and rear seats. The front seats (not shown in the figure) are located near the front of the car along the length X direction, and the rear seats (not shown in the figure) are located near the rear of the car along the length X direction. The front seats include the driver's seat (not shown in the figure) and the front passenger seat (not shown in the figure), which are located on opposite sides of the car and spaced apart along the width Y direction. Between the driver's seat and the front passenger seat are functional components of the car (not shown in the figure), such as the center console and gear shift lever.

[0143] refer to Figure 6 and combined Figure 5a In the vehicle-mounted inflatable mattress 100 of this application embodiment, the second support body 400 and the first support body 300 are spaced apart along the width direction Y, forming a first clearance space 600. Along the length direction X, the first support body 300 and the second support body 400 are located on the same side of the third support body 500. Furthermore, both the first support body 300 and the second support body 400 extend along the length direction X, while the third support body 500 extends along the width direction Y. Thus, the first support body 300, the second support body 400, and the third support body 500 are arranged in a "U" shape.

[0144] Accordingly, refer to Figure 5a and combined Figure 6 The air mattress body 200 is also U-shaped. Specifically, the air mattress body 200 includes a first main body 210, a second main body 220, and a third main body 230. A first support 300 is located at the bottom of the first main body 210, a second support 400 is located at the bottom of the second main body 220, and a third support 500 is located at the bottom of the third main body 230. Along the width direction Y, the second main body 220 and the first main body 210 are spaced apart to form a second clearance space 240. Along the length direction X, the first main body 210 and the second main body 220 are located on the same side of the third main body 230. Furthermore, the first main body 210 and the second main body 220 both extend along the length direction X, and the third main body 230 extends along the width direction Y. Thus, the first main body 210, the second main body 220, and the third main body 230 are arranged in a U-shape.

[0145] When using the vehicle-mounted inflatable mattress 100, the first support 300 is placed above the driver's seat, the second support 400 is placed above the passenger seat, and the third support 500 is placed above the rear seats. The first clearance space 600 and the second clearance space 240 together avoid obstacles such as the center console and gear shift lever. Thus, the first support 300, the second support 400, and the third support 500 together support the main body of the inflatable mattress 200 in a horizontal or near-horizontal position for the user to rest. In other words, the first support 300, the second support 400, and the third support 500 play a "filling" role, leveling uneven areas inside the car (such as the seat cushions of the driver's seat, passenger seat, and rear seats), thereby keeping the tops of the first support 300, the second support 400, and the third support 500 at the same height. This, in turn, keeps the inflatable bed body 200 above it in a horizontal or near-horizontal state, effectively preventing the inflatable bed 100 from shaking during use, avoiding danger, and providing users with a good user experience.

[0146] Specifically, in some possible usage scenarios, the backrests of the driver's seat and the passenger seat are folded forward (i.e., towards the front of the car along the length direction X), so that the first support 300 is placed on the backrest of the driver's seat and the second support 400 is placed on the backrest of the passenger seat.

[0147] In other possible use cases, the backrests of the driver's seat and passenger seat are folded back (i.e., towards the rear of the vehicle along the length X direction). This allows the first support 300 to be placed on the driver's seat cushion or backrest, or a portion of the first support 300 to be placed on the driver's seat cushion and another portion on the driver's seat backrest. Similarly, the second support 400 is placed on the passenger seat cushion or backrest, or a portion of the second support 400 to be placed on the passenger seat cushion and another portion on the passenger seat backrest.

[0148] In some possible use cases, the backrests of the rear seats of the car are folded forward (i.e., towards the front of the car along the length direction X), thereby placing the third support 500 above the backrests of the rear seats.

[0149] In other possible use cases, the backrests of the rear seats of the car are folded back (i.e., in the direction of the rear of the car along the length X), so that the third support 500 is placed on the seat cushion or backrest of the rear seat, or a portion of the third support 500 is placed on the seat cushion of the rear seat and another portion is placed on the backrest of the rear seat.

[0150] It should be noted that the specific shape of the air mattress body 200 is not specifically limited in this embodiment. For example, in other possible implementations, the specific shape of the air mattress body 200 can be rectangular, trapezoidal, or fan-shaped, etc., and can be adapted to the space inside the car. However, it should be ensured that the first clearance space 600 formed by the first support 300 and the second support 400 can avoid the car functional components located between the driver's seat and the passenger seat, so as to avoid the air mattress 100 from being squeezed by the car functional components, causing damage or malfunction of the car functional components, or causing damage to the air mattress 100.

[0151] For example, refer to Figure 6 In this embodiment of the application, along the length direction X, the length L1 of the first support 300 and the length L2 of the second support 400 are equal. However, this is not the limitation. In other possible embodiments, the length L1 of the first support 300 is greater than the length L2 of the second support 400, or the length L2 of the second support 400 is greater than the length L1 of the first support 300, which can be adjusted according to actual needs.

[0152] Continue to refer to Figure 6 In this embodiment of the application, along the width direction Y, the width W1 of the first support 300 and the width W2 of the second support 400 are equal, but not limited thereto. In other possible embodiments, the width W1 of the first support 300 is greater than the width W2 of the second support 400, or the width W2 of the second support 400 is greater than the width W1 of the first support 300, which can be adjusted according to actual needs.

[0153] In this embodiment of the application, the air bed body 200, the first support 300, the second support 400, and the third support 500 can be as follows: Figures 1 to 4 The gas filling shown.

[0154] Specifically, refer to Figure 7 The air mattress body 200 includes an upper piece 201 and a lower piece 202. The lower piece 202 and the upper piece 201 are disposed opposite to each other along the height direction Z and connected to each other to define a main inflation chamber 203. The upper piece 201 or the lower piece 202 is provided with an air valve (not shown), which is used to inflate or deflate the main inflation chamber 203. The air valve may also be located at the connection between the upper piece 201 and the lower piece 202. Exemplarily, the shapes of the upper piece 201 and the lower piece 202 are adapted to the shape of the air mattress body 200, both being "U"-shaped.

[0155] When using the vehicle-mounted inflatable mattress 100, the user sits or lies on the main body 200 of the inflatable mattress, with their body in contact with the upper sheet 201. In this embodiment, a layer of sponge 250 is provided inside the inflation chamber 203. The sponge 250 is connected to the inner surfaces of the upper sheet 201 and the lower sheet 202 by means of heat melting, adhesive bonding, etc., thereby improving the softness of the upper sheet 201 and providing the user with a more comfortable experience.

[0156] In some possible implementations, the sponge 250 may be attached only to the inner surface of the upper sheet 201, or the sponge 250 may be attached only to the inner surface of the lower sheet 202.

[0157] For example, continue to refer to Figure 7 In some possible implementations, the sponge 250 is provided with a plurality of weight-reducing holes 251. Each weight-reducing hole 251 extends along the width direction Y and penetrates the sponge 250. The plurality of weight-reducing holes 251 are spaced apart along the length direction X. The weight-reducing holes 251 can effectively reduce the weight of the sponge 250, thereby reducing the weight of the vehicle-mounted air mattress 100, making the vehicle-mounted air mattress 100 of this embodiment lighter, easier to carry and use.

[0158] For example, the sponge 250 in this embodiment is a single piece of sponge. In other possible implementations, the sponge 250 may also be composed of multiple pieces of sponge spliced ​​together.

[0159] In other possible implementations, the main inflation chamber 203 does not contain a sponge 250, but instead contains multiple sponges such as... Figures 1 to 4 The tensioning member 20 shown in the embodiment. One end of the plurality of tensioning members 20 is connected to the upper piece 201 by means of welding, adhesive bonding or the like, and the other end is connected to the lower piece 202 by means of welding, adhesive bonding or the like.

[0160] In some possible implementations, the upper sheet 201 and the lower sheet 202 are connected to each other via side sheets (not shown). Specifically, the upper edge of the side sheet is connected to the outer edge of the upper sheet 201, and the lower edge of the side sheet is connected to the outer edge of the lower sheet 202, thereby the upper sheet 201, the lower sheet 202, and the side sheet together define the main inflation chamber 203. Exemplarily, the air valve of the air bed body 200 may also be provided on the side sheet.

[0161] refer to Figure 8 and combined Figure 7 The first support 300 includes: a first top piece 301, a first bottom piece 302, and two first side pieces 340. Figure 8Only one first side piece 340 is shown in the figure. Along the height direction Z, the first top piece 301 and the first bottom piece 302 are arranged opposite each other. Along the length direction X, one end of the first top piece 301 is connected to one end of the first bottom piece 302, and the other end of the first top piece 301 is connected to the other end of the first bottom piece 302. Along the width direction Y, two first side pieces 340 are located on opposite sides of the first top piece 301 and the first bottom piece 302, respectively. Specifically, along the width direction Y, one end of the first top piece 301 is connected to the first bottom piece 302 via one first side piece 340, and the other end of the first top piece 301 is connected to the first bottom piece 302 via the other first side piece 340. Thus, the first top piece 301 and the first bottom piece 302 define a first inflation chamber (not shown in the figure). The first inflation chamber is provided with a plurality of first tensioning members (not shown in the figure), which can be as follows: Figures 1 to 4 Tensioning member 20 as shown in any embodiment. One end of a plurality of first tensioning members is connected to a first top plate 301 by means of welding, adhesive bonding or the like to form a first top plate weld 303, and the other end is connected to a first bottom plate 302 by means of welding, adhesive bonding or the like to form a first bottom plate weld (not shown).

[0162] In this embodiment, each of the plurality of first tensioning members extends along the width direction Y, and the plurality of first tensioning members are spaced apart along the length direction X. Correspondingly, each first top plate weld 303 extends along the width direction Y, and the plurality of first top plate welds 303 are spaced apart along the length direction X. Each first bottom plate weld extends along the width direction Y, and the plurality of first bottom plate welds are spaced apart along the length direction X. The height (dimension along the height direction Z) of each first tensioning member can be the same or different. In this embodiment, the height of the first tensioning member changes sequentially along the length direction X to form a predetermined concave-convex shape on the first bottom plate 302. The concave-convex shape formed by the first bottom plate 302 matches the shape of the upper surface of the driver's seat backrest after it is laid flat, thereby enabling the first support 300 to fill the recess of the driver's seat, thereby making the upper surface of the first support 300 (i.e., the first top plate 301) in a horizontal or nearly horizontal state. In other embodiments, the height distribution of the first tensioning members can be changed according to the shape of different driver's seats.

[0163] The present application does not impose specific restrictions on the extension direction of the first tensioning member. In other possible implementations, the first tensioning member may also extend along the length direction X, and multiple first tensioning members may be spaced apart along the width direction Y.

[0164] When the vehicle-mounted air mattress 100 is in use, the first top piece 301 of the first support body 300 contacts the lower piece 202 of the air mattress body 200, and the first bottom piece 302 of the first support body 300 contacts the driver's seat of the car.

[0165] For example, the first top piece 301 is provided with a first connecting valve 330, and the lower piece 202 of the air bed body 200 is provided with a second connecting valve (not shown in the figure). The first connecting valve 330 is connected to the second connecting valve so that the first inflation chamber is connected to the main inflation chamber 203. Thus, by inflating the main inflation chamber 203, both the air bed body 200 and the first support 300 can be inflated simultaneously, and by deflating the main inflation chamber 203, both the air bed body 200 and the first support 300 can be deflated simultaneously.

[0166] It should be noted that, in other possible embodiments, the first support 300 may only have one first side piece 340, which surrounds the first support 300. The first top piece 301 and the first bottom piece 302 are not directly connected. Along the height direction Z, the upper edge of the first side piece 340 is connected to the outer edge of the first top piece 301, and the lower edge of the first side piece 340 is connected to the outer edge of the first bottom piece 302, thereby defining the first inflation chamber.

[0167] In some other possible implementations, the outer edge of the first top sheet 301 and the outer edge of the first bottom sheet 302 may be directly connected, that is, the first support 300 does not include the first side sheet 340.

[0168] Continue to refer to Figure 8 and combined Figure 7 The second support 400 includes: a second top sheet 401, a second bottom sheet 402, and two second side sheets 440. Figure 8 Only one second side piece 440 is shown in the figure. Along the height direction Z, the second top piece 401 and the second bottom piece 402 are arranged opposite each other. Along the length direction X, one end of the second top piece 401 is connected to one end of the second bottom piece 402, and the other end of the second top piece 401 is connected to the other end of the second bottom piece 402. Along the width direction Y, the two second side pieces 440 are located on opposite sides of the second top piece 401 and the second bottom piece 402, respectively. Specifically, along the width direction Y, one end of the second top piece 401 is connected to the second bottom piece 402 via one second side piece 440, and the other end of the second top piece 401 is connected to the second bottom piece 402 via the other second side piece 440, thereby defining a second inflation chamber (not shown in the figure). A second tensioning member is provided within the second inflation chamber, and the second tensioning member can be as follows: Figures 1 to 4 Tensioning member 20 as shown in any embodiment. One end of a plurality of second tensioning members is connected to the second top plate 401 by means of welding, adhesive bonding or the like to form a second top plate weld 403, and the other end is connected to the second bottom plate 402 by means of welding, adhesive bonding or the like to form a second bottom plate weld (not shown).

[0169] In this embodiment, each of the plurality of second tensioning members extends along the width direction Y, and the plurality of second tensioning members are spaced apart along the length direction X. Correspondingly, each second top plate weld 403 extends along the width direction Y, and the plurality of second top plate welds 403 are spaced apart along the length direction X. Each second bottom plate weld extends along the width direction Y, and the plurality of second bottom plate welds are spaced apart along the length direction X. The height (dimension along the height direction Z) of each second tensioning member can be the same or different. In this embodiment, the height of the second tensioning member changes sequentially along the length direction X to form a predetermined concave-convex shape on the second bottom plate 402. The concave-convex shape formed by the second bottom plate 402 matches the shape of the upper surface of the passenger seat backrest after it is laid flat, thereby enabling the second support 400 to fill the recess of the passenger seat, thereby making the upper surface of the second support 400 (i.e., the second top plate 401) in a horizontal or nearly horizontal state. In other embodiments, the height distribution of the second tensioning members can be changed according to the shape of different passenger seats.

[0170] The present application does not impose specific restrictions on the extension direction of the second tensioning member. In other possible implementations, the second tensioning member may also extend along the length direction X, and multiple second tensioning members may be spaced apart along the width direction Y.

[0171] When the vehicle-mounted air mattress 100 is in use, the second top piece 401 of the second support body 400 contacts the lower piece 202 of the air mattress body 200, and the second bottom piece 402 of the second support body 400 contacts the passenger seat of the car.

[0172] For example, the second top piece 401 is provided with a third connecting valve 430, and the lower piece 202 of the air bed body 200 is provided with a fourth connecting valve (not shown in the figure). The third connecting valve 430 is connected to the fourth connecting valve so that the second air chamber is connected to the main air chamber 203. Thus, by inflating the main air chamber 203, the air bed body 200 and the second support 400 can be inflated simultaneously, and by deflating the main air chamber 203, the air bed body 200 and the second support 400 can be deflated simultaneously.

[0173] It should be noted that, in other possible embodiments, the second support 400 may be provided with only one second side piece 440, which surrounds the second support 400. The second top piece 401 and the second bottom piece 402 are not directly connected. Along the height direction Z, the upper edge of the second side piece 440 is connected to the outer edge of the second top piece 401, and the lower edge of the second side piece 440 is connected to the outer edge of the second bottom piece 402, thereby defining the second inflation chamber.

[0174] In some other possible implementations, the outer edge of the second top sheet 401 and the outer edge of the second bottom sheet 402 may be directly connected, that is, the second support 400 does not include the second side sheet 440.

[0175] Continue to refer to Figure 8 and combined Figure 7 The third support 500 includes a third top piece 501, a third bottom piece 502, and a third side piece 560, the third side piece 560 being disposed around the third support 500. Along the height direction Z, the third top piece 501 and the third bottom piece 502 are disposed opposite each other. Along the height direction Z, the upper edge of the third side piece 560 is connected to the outer edge of the third top piece 501, and the lower edge of the third side piece 560 is connected to the outer edge of the third bottom piece 502. Thus, the third top piece 501, the third bottom piece 502, and the third side piece 560 together define a third inflation chamber (not shown). The third inflation chamber is provided with a plurality of third tensioning members, which can be, for example,... Figures 1 to 4 Tensioning member 20 as shown in any embodiment. One end of a plurality of third tensioning members is connected to the third top plate 501 by means of, for example, welding or gluing, and the other end is connected to the third bottom plate 502 by means of, for example, welding or gluing.

[0176] For example, a portion of the plurality of third tensioning members extends along the width direction Y, and the third tensioning members of this portion are spaced apart along the length direction X. A plurality of third top plate transverse welds 503 extending along the width direction Y are formed on the third top plate 501, and a plurality of third bottom plate transverse welds extending along the width direction Y are formed on the third bottom plate 502 (not shown). Another portion of the plurality of third tensioning members extends along the length direction X, and the third tensioning members of this portion are spaced apart along the width direction Y. A plurality of third top plate longitudinal welds 504 extending along the length direction X are formed on the third top plate 501, and a plurality of third bottom plate longitudinal welds extending along the length direction X are formed on the third bottom plate 502 (not shown). Specifically, the third top plate transverse weld 503 and the third bottom plate transverse weld are distributed on the third support body 500 on the portion of the first support body 300 and the second support body 400 along the length direction X near the rear of the vehicle. The third top plate longitudinal weld 504 and the third bottom plate longitudinal weld are distributed on the third support body 500 on the portion of the first clearance space 600 along the length direction X near the rear of the vehicle. That is, along the width direction Y, the third top plate 501 has the third top plate transverse weld 503, the third top plate longitudinal weld 504, and the third bottom plate transverse weld 503 in sequence, and the third bottom plate 502 has the third bottom plate transverse weld, the third bottom plate longitudinal weld, and the third bottom plate transverse weld in sequence. Furthermore, in this embodiment, the height of the third tensioning member located between the longitudinal weld seam 504 of the third top plate and the longitudinal weld seam of the third bottom plate is less than the height of the third tensioning member located between the transverse weld seam 503 of the third top plate and the transverse weld seam of the third bottom plate, thereby forming a recess on the third top plate 501 and the third bottom plate 502 of the third support 500 to match the shape of the protrusion at the edge of the seat.

[0177] The present application does not impose specific limitations on the extension direction of the third tensioning member. In other possible embodiments, the plurality of third tensioning members may all extend along the length direction X, and the plurality of third tensioning members may be spaced apart along the width direction Y. In some other possible embodiments, the plurality of third tensioning members may all extend along the width direction Y, and the plurality of third tensioning members may be spaced apart along the length direction X.

[0178] When the vehicle-mounted air mattress 100 is in use, the third top piece 501 contacts the lower piece 202 of the air mattress body 200, and the third bottom piece 502 contacts the rear seat of the car.

[0179] For example, the third top piece 501 is provided with a fifth connecting valve 550, and the lower piece 202 of the air bed body 200 is provided with a sixth connecting valve (not shown in the figure). The fifth connecting valve 550 is connected to the sixth connecting valve so that the third air chamber is connected to the main air chamber 203. Thus, by inflating the main air chamber 203, both the air bed body 200 and the third support 500 can be inflated simultaneously, and by deflating the main air chamber 203, both the air bed body 200 and the third support 500 can be deflated simultaneously.

[0180] In this embodiment, the air bed body 200, the first support 300, the second support 400, and the third support 500 are all inflated with gas, and the air bed body 200, the first support 300, the second support 400, and the third support 500 are independent of each other, which makes it easy to disassemble the air bed body 200 for storage and carrying.

[0181] Meanwhile, in this embodiment of the application, a first connecting valve 330 is provided on the first support body 300, a third connecting valve 430 is provided on the second support body 400, a fifth connecting valve 550 is provided on the third support body 500, and a second connecting valve for connecting to the first connecting valve 330, a fourth connecting valve for connecting to the third connecting valve 430, and a sixth connecting valve for connecting to the fifth connecting valve 550 are provided on the air bed body 200. This allows the main inflation chamber 203 to communicate with the first inflation chamber, the second inflation chamber, and the third inflation chamber. When using the air bed, the user only needs to inflate or deflate the air bed body 200 to inflate or deflate the first support body 300, the second support body 400, and the third support body 500, providing convenience for the user's operation.

[0182] Furthermore, the connection between the first connecting valve 330 and the second connecting valve can connect the first support 300 and the air bed body 200. Correspondingly, the connection between the third connecting valve 430 and the fourth connecting valve can connect the second support 400 and the air bed body 200, and the connection between the fifth connecting valve 550 and the sixth connecting valve can connect the third support 500 and the air bed body 200, effectively improving the stability of the support provided by the first support 300, the second support 400 and the third support 500 to the air bed body 200.

[0183] It is understood that the specific location of the air valve is not specifically limited in the embodiments of this application. For example, in some possible implementations, the air valve may also be set in any one of the first support 300, the second support 400 and the third support 500.

[0184] The number of air valves is not specifically limited in this application embodiment. For example, in some possible implementations, the number of air valves may be two, three, or four. Exemplarily, in other possible implementations, air valves may be provided on any two, three, or four of the air bed body 200, the first support 300, the second support 400, and the third support 500.

[0185] Exemplarily, in some possible implementations, the first support 300, the second support 400, and the third support 500 may be integrally formed. That is, the first support 300, the second support 400, and the third support 500 are different parts of the same gas-filled structure, and the gas filling has a "U"-shaped structure. In possible implementations, the first top piece 301 of the first support 300, the second top piece 401 of the second support 400, and the third top piece 501 of the third support 500 are integrally formed, or the first top piece 301, the second top piece 401, and the third top piece 501 are different parts of the same sheet (e.g., a "U"-shaped sheet). Accordingly, the first substrate 302 of the first support 300, the second substrate 402 of the second support 400, and the third substrate 502 of the third support 500 are integrally formed, or in other words, the first substrate 302, the second substrate 402, and the third substrate 502 are different parts of the same sheet (e.g., a "U"-shaped sheet). Correspondingly, the first inflation chamber, the second inflation chamber, and the third inflation chamber are interconnected.

[0186] Exemplarily, in some other possible embodiments, the first support 300 and the third support 500 are integrally formed. That is, the first support 300 and the third support 500 are different parts of the same gas-filled structure, and the gas filling is L-shaped, while the second support 400 is a gas-filled structure independent of the first support 300 and the third support 500. In possible embodiments, the first top sheet 301 of the first support 300 and the third top sheet 501 of the third support 500 are integrally formed, or the first top sheet 301 and the third top sheet 501 are different parts of the same sheet (e.g., an L-shaped sheet). Correspondingly, the first bottom sheet 302 of the first support 300 and the third bottom sheet 502 of the third support 500 are integrally formed, or the first bottom sheet 302 and the third bottom sheet 502 are different parts of the same sheet (e.g., an L-shaped sheet). Correspondingly, the first inflation chamber and the third inflation chamber are interconnected, while the second inflation chamber is independent of the first inflation chamber and the third inflation chamber.

[0187] Exemplarily, in other possible embodiments, the second support 400 and the third support 500 are integrally formed. That is, the second support 400 and the third support 500 are different parts of the same gas-filled structure, and the gas filling is L-shaped, while the first support 300 is an independent gas-filled structure separate from the second support 400 and the third support 500. In this embodiment, the second top piece 401 of the second support 400 and the third top piece 501 of the third support 500 are integrally formed, or in other words, the second top piece 401 and the third top piece 501 are different parts of the same sheet (e.g., an L-shaped sheet). Correspondingly, the second bottom piece 402 of the second support 400 and the third bottom piece 502 of the third support 500 are integrally formed, or in other words, the second bottom piece 402 and the third bottom piece 502 are different parts of the same sheet (e.g., an L-shaped sheet). Correspondingly, the second and third inflation chambers are interconnected, while the first inflation chamber is independent of the second and third inflation chambers.

[0188] Continue to refer to Figure 6 and combined Figure 5a For example, the third support 500 includes a first portion 510, a second portion 520, and a third portion 530. Along the width direction Y, the third portion 530 is located between the first portion 510 and the second portion 520. When the vehicle-mounted air mattress 100 is in use, the first portion 510 is placed on the left side of the rear seat of the vehicle (the seat behind the driver's seat), and the second portion 520 is placed on the right side of the rear seat of the vehicle (the seat behind the front passenger seat). Along the height direction Z, the side of the third portion 530 away from the air mattress body 200 (i.e., the portion of the third portion 530 located on the third base plate 502) is recessed towards the air mattress body 200, forming a recess 532.

[0189] For example, in some cars, the rear seats consist of only a left and a right rear seat. The edge of the left rear seat is higher than the center cushion of the left rear seat, and the edge of the right rear seat is higher than the center cushion of the right rear seat. Therefore, in scenarios where the third support 500 is placed on the rear seat cushion, the recess 532 effectively avoids the protruding parts of the edges of the left and right rear seats, allowing the third support 500 to keep the third main body 230 of the inflatable bed body 200 in a horizontal or near-horizontal state.

[0190] In some possible implementations, the shape of the recess 532 is adapted to the shape of the protruding portion of the edge of the left rear seat and the protruding portion of the edge of the right rear seat, so that the portion between the left and right rear seats engages with the recess 532.

[0191] For example, refer to Figure 8 and combined Figure 5a and Figure 6 Along the height direction Z, the third portion 530 is recessed in the direction away from the air mattress body 200 (i.e., the portion of the third portion 530 located on the third top plate 501) to form an upper recess 531. Thus, when the vehicle-mounted air mattress 100 is in use, the lower recess 532, the first portion 510, and the second portion 520 define a third clearance space (not shown in the figure).

[0192] It is understandable that, along the height direction Z, the height of the third tensioning member located at the upper recess 531 and lower recess 532 within the third support 500 is less than the height of the third tensioning member at other locations.

[0193] For example, in some cars, the edge of the left rear seat is higher than the center cushion of the left rear seat, and the edge of the right rear seat is higher than the center cushion of the right rear seat. Therefore, in scenarios where the third support 500 is placed on the rear seat cushion, a third clearance space is provided for the edge of the seat to pass through. Furthermore, in some cars, the rear seats consist only of a left and a right rear seat, with a center armrest (not shown) located between the left and right rear seats. Therefore, in scenarios where the third support 500 is placed on the rear seat cushion, a third clearance space is provided for the center armrest to pass through, thus avoiding obstruction to the center armrest.

[0194] refer to Figure 6 and combined Figure 5a For example, the first support 300 includes a first recess 310, which is located on the side of the first support 300 away from the air mattress body 200 (i.e., the first base plate 302), and the first recess 310 is located at the middle position of the first base plate 302 along the length direction X, and the first recess 310 is recessed towards the air mattress body 200. That is, along the length direction X, the first support 300 forms a convex shape on the adjacent sides of the first recess 310 to match the recessed shape on the passenger seat. When the backrest of the driver's seat of the car is folded back (i.e., towards the rear of the car along the length direction X), so that a part of the first support 300 is placed on the seat cushion of the driver's seat and another part is placed on the backrest of the driver's seat, in this usage scenario, the first recess 310 can avoid the position where the seat cushion of the driver's seat connects to the backrest, so that the first support 300 holds the first main body portion 210 of the air mattress body 200 in a horizontal or nearly horizontal position.

[0195] The specific location of the first recess 310 is not specifically limited in this embodiment. For example, in other possible implementations, the first recess 310 is located near the end of the first film 302 along the length direction X, and can be adaptively adjusted according to actual needs.

[0196] It is understandable that, along the height direction Z, the height of the first tensioning member located at the first recess 310 within the first support 300 is less than the height of the first tensioning member at other locations.

[0197] For example, in other possible implementations, the first support 300 may not have the first recess 310.

[0198] Continue to refer to Figure 6 and combined Figure 5a For example, the second support 400 includes a second recess 410, which is located on the side of the second support 400 away from the air mattress body 200 (i.e., the second base plate 402), and the second recess 410 is located at the middle position of the second base plate 402 along the length direction X, and the second recess 410 is recessed towards the air mattress body 200. That is, along the length direction X, the second support 400 forms a protruding shape on the adjacent sides of the second recess 410 to match the recessed shape on the passenger seat. When the backrest of the passenger seat of the car is folded back (i.e., towards the rear of the car along the length direction X), a part of the second support 400 is placed on the passenger seat cushion and another part is placed on the passenger seat back. In this usage scenario, the second recess 410 can avoid the position where the passenger seat cushion connects to the backrest, so that the second support 400 holds the second main body portion 220 of the air mattress body 200 in a horizontal or nearly horizontal position.

[0199] The specific location of the second recess 410 is not specifically limited in this application embodiment. For example, in other possible implementations, the second recess 410 is located near the end of the second film 402 along the length direction X, and can be adaptively adjusted according to actual needs.

[0200] It is understandable that, along the height direction Z, the height of the second tensioning member located at the second recess 410 within the second support 400 is less than the height of the second tensioning member at other locations.

[0201] For example, in other possible implementations, the second support 400 may not have the second recess 410.

[0202] refer to Figure 6 and combined Figure 5aFor example, along the length direction X, the third portion 530 is recessed toward the first support 300 and the second support 400 on the side away from the first support 300 and the second support 400 (i.e., the portion of the third portion 530 located at the third side piece 560) to form a first rear recess 533. Correspondingly, along the length direction X, the third main body portion 230 of the air bed body 200 is recessed toward the first main body portion 210 and the second main body portion 220 on the side away from the first main body portion 210 and the second main body portion 220 to form a second rear recess 260.

[0203] In some cars, the first rear recess 533 and the second rear recess 260 are able to avoid the portion between the backrest of the left rear seat and the backrest of the right rear seat.

[0204] For example, refer to Figure 6 and combined Figure 5a The vehicle-mounted inflatable mattress 100 in this embodiment of the application further includes: two first connecting pieces 320 ( Figure 6 Only one first connecting piece 320 and two second connecting pieces 420 are shown in the image. Figure 6 Only one second connecting piece 420 and two third connecting pieces 540 are shown. The first connecting piece 320 is connected to the air bed body 200 and the first support 300, the second connecting piece 420 is connected to the air bed body 200 and the second support 400, and the third connecting piece 540 is connected to the air bed body 200 and the third support 500.

[0205] Specifically, along the width direction Y, two first connecting pieces 320 are located on opposite sides of the first support body 300. One end of each first connecting piece 320 is connected to the air mattress body 200 (e.g., the upper piece 201 or lower piece 202 of the air mattress body 200; in some possible embodiments, it may also be a side piece of the air mattress body 200) via a means such as high frequency, heat pressing, adhesive, zipper, or button. The other end is connected to the first support body 300 (e.g., the first top piece 301, first bottom piece 302, or first side piece 340 of the first support body 300) via the same means. This allows the first support body 300 to be stably connected to the air mattress body 200, further improving the support stability of the first support body 300 for the air mattress body 200.

[0206] It should be noted that the specific positions of the two first connecting pieces 320 are not specifically limited in this application embodiment. For example, in some possible implementations, the two first connecting pieces 320 are located on opposite sides of the first support 300 along the length direction X.

[0207] The specific number of the first connecting piece 320 is not specifically limited in this application embodiment. For example, in other possible implementations, the number of the first connecting piece 320 may be one, or three, four, or five, etc.

[0208] For example, along the width direction Y, two second connecting pieces 420 are located on opposite sides of the second support body 400. One end of each second connecting piece 420 is connected to the air mattress body 200 (e.g., the upper piece 201 or lower piece 202 of the air mattress body 200; in some possible embodiments, it may also be a side piece of the air mattress body 200) via a means such as high frequency, heat pressing, adhesive, zipper, or button. The other end is connected to the second support body 400 (e.g., the second top piece 401, second bottom piece 402, or second side piece 440 of the second support body 400) via a means such as high frequency, heat pressing, adhesive, zipper, or button. This allows the second support body 400 to be stably connected to the air mattress body 200, further improving the support stability of the second support body 400 for the air mattress body 200.

[0209] It should be noted that the specific positions of the two second connecting pieces 420 are not specifically limited in this application embodiment. For example, in some possible implementations, the two second connecting pieces 420 are located on opposite sides of the second support 400 along the length direction X.

[0210] The specific number of the second connecting piece 420 is not specifically limited in this application embodiment. For example, in other possible implementations, the number of the second connecting piece 420 may be one, or three, four, or five, etc.

[0211] For example, along the width direction Y, two third connecting pieces 540 are located on opposite sides of the third support 500. One end of each third connecting piece 540 is connected to the air mattress body 200 (e.g., the upper piece 201 or lower piece 202 of the air mattress body 200; in some possible embodiments, it may also be a side piece of the air mattress body 200) via a means such as high frequency, heat pressing, adhesive, zipper, or button. The other end is connected to the third support 500 (e.g., the third top piece 501, third bottom piece 502, or third side piece 560 of the third support 500) via a means such as high frequency, heat pressing, adhesive, zipper, or button. This allows the third support 500 to be stably connected to the air mattress body 200, further improving the support stability of the third support 500 for the air mattress body 200. Therefore, the third support 500 can be stably connected to the air bed body 200, further improving the support stability of the third support 500 on the air bed body 200.

[0212] It should be noted that the specific positions of the two third connecting pieces 540 are not specifically limited in this application embodiment. For example, in some possible implementations, the two third connecting pieces 540 are located on opposite sides of the third support 500 along the length direction X.

[0213] The specific number of the third connecting piece 540 is not specifically limited in this application embodiment. For example, in other possible implementations, the number of the third connecting piece 540 may be one, or three, four, or five, etc.

[0214] Exemplarily, in possible embodiments, the first connecting piece 320 includes a first sheet and a second sheet, wherein the first sheet is fixed to the air mattress body 200, the second sheet is fixed to the first support 300, and the second sheet is connected to the first sheet by means such as high frequency, heat pressing, adhesive, zipper, or button. The second connecting piece 420 includes a third sheet and a fourth sheet, wherein the third sheet is fixed to the air mattress body 200, the fourth sheet is fixed to the second support 400, and the fourth sheet is connected to the third sheet by means such as high frequency, heat pressing, adhesive, zipper, or button. The third connecting piece 540 includes a fifth sheet and a sixth sheet, wherein the fifth sheet is fixed to the air mattress body 200, the sixth sheet is fixed to the third support 500, and the sixth sheet is connected to the fifth sheet by means such as high frequency, heat pressing, adhesive, zipper, or button.

[0215] The embodiments of this application do not impose special restrictions on the specific structure of the first connecting piece 320, the second connecting piece 420, and the third connecting piece 540. For example, in other possible implementations, the first connecting piece 320, the second connecting piece 420, and the third connecting piece 540 are all single-layer sheets.

[0216] Exemplarily, in other embodiments, such as Figure 9 As shown, with Figure 6The difference in the illustrated embodiment is that, along the length direction X, from the portion near the front of the vehicle to the portion near the rear, the width (dimension along the width direction Y) of the third support 500 narrows. Specifically, the third support 500 sequentially includes a support width portion 570, a support contraction portion 580, and a support narrow portion 590. Along the length direction X, the support width portion 570 of the third support 500 is located near the front of the vehicle, the support narrow portion 590 is located near the rear of the vehicle, and the support contraction portion 580 is located between the support width portion 570 and the support narrow portion 590. Further, along the length direction X, from the portion near the front of the vehicle to the portion near the rear, the width (dimension along the width direction Y) of the third main body portion 230 of the air mattress body 200 narrows. Specifically, the third main body portion 230 of the air mattress body 200 sequentially includes a main body contraction portion 231 and a main body narrow portion 232. Along the length direction X, the main body contraction portion 231 of the third main body portion 230 is located near the front of the vehicle, and the main body narrow portion 232 of the third main body portion 230 is located near the rear of the vehicle. When the vehicle-mounted air mattress is in use, the first support body 300 is located on and in contact with the left rear seat of the vehicle, the second support body 400 is located on and in contact with the right rear seat of the vehicle, and the third support body 500 is located in the trunk of the vehicle and in contact with the bottom of the trunk; the main body narrow portion 232 is located on and supported by the support narrow portion 590, and the main body contraction portion 231 is located on and supported by the support wide portion 570 and the support contraction portion 580. This application does not restrict the state of the vehicle-mounted air mattress during use. For example, the first support 300 is located on the driver's seat and in contact with the driver's seat, the second support 400 is located on the passenger seat and in contact with the passenger seat, and the third support 500 is located on the rear seats and the bottom of the trunk and in contact with the rear seats and the bottom of the trunk, etc.

[0217] In some possible embodiments, the third support 500 may only include a support contraction portion 580 and a support narrow portion 590. That is, along the length direction X, the width of the third support 500 begins to narrow from the end near the front of the vehicle until it reaches the boundary between the support contraction portion 580 and the support narrow portion 590, after which the width of the third support 500 remains unchanged. Alternatively, the third main body portion 230 of the air bed body 200 may also include a main body wide portion (not shown), a main body contraction portion 231, and a main body narrow portion 232. Correspondingly, the support relationship between the third support body 500 and the third main body portion 230 of the air bed body 200 may also be different. For example, when the third main body portion 230 of the air bed body 200 includes a main body wide portion, a main body contraction portion 231, and a main body narrow portion 232, and the third support body 500 sequentially includes a support wide portion 570, a support contraction portion 580, and a support narrow portion 590, the main body wide portion of the third main body portion 230 may be supported by the support wide portion 570 of the third support body 500, the main body contraction portion 231 of the third main body portion 230 may be supported by the support contraction portion 580 of the third support body 500, the main body narrow portion 232 of the third main body portion 230 may be supported by the support narrow portion 590 of the third support body 500, and so on. This application does not impose any limitations on this.

[0218] By way of example, in other embodiments, at least a portion of the air mattress body 200 may directly contact the vehicle seat, or at least a portion of the air mattress body 200 may directly contact the vehicle trunk, meaning the air mattress body 200 is not supported by a support structure, or is only partially supported by a support structure. (See reference...) Figure 10a and Figure 10b The bottom of the air mattress body 200 can be configured with different shapes. Specifically, along the length direction X, the air mattress body 200 contains a sponge 250 ( Figure 7 (As shown), the sponge 250 is connected to the inner surfaces of the upper sheet 201 and the lower sheet 202 by means of heat melting, adhesive bonding, etc. The sponge 250 can have multiple different heights, thereby giving the air mattress body 200 multiple mating portions 270 and transition portions 280 of different heights. For example, a portion of the bottom surface of the sponge 250 can be a plane, thus the bottom surface of the mating portion 270 of the air mattress body 200 is a plane; a portion of the bottom surface of the sponge 250 can be a slope, an arc surface, or an irregular curved surface, thus the bottom surface of the transition portion 280 of the air mattress body 200 is a slope (e.g., ...). Figure 10a As shown), curved surface (as shown) Figure 10b(As shown) or an irregular curved surface. Further, the sponge 250 can be a single, unique unit, or a combination of multiple individual sponges, with the number of individual sponges being 2, 3, 4, 5, etc. When the sponge 250 is a combination of multiple individual sponges, adjacent individual sponges can be tightly pressed together without gaps, or adjacent individual sponges can be spaced apart to maintain some spacing. For example, the distance between two adjacent individual sponges that are spaced apart is less than 10cm. Thus, through the spacing between adjacent individual sponges, the surface of the air mattress body 200 will have some patterns due to the spacing between the individual sponges, achieving an aesthetic effect. In some other possible embodiments, the internal filling of the air mattress body 200 consists of multiple individual sponges, all of which have the same height and no height difference. When the vehicle-mounted air mattress 100 is placed inside a vehicle, it contacts the vehicle seat through the mating part 270, or through the mating part 270 and the transition part 280, and the corresponding part of the air mattress body 200 is directly supported by the vehicle's interior structure. This application does not limit the internal structure of the air mattress body 200. For example, in some other possible embodiments, the air mattress body 200 may not contain the sponge 250, but instead may contain something like... Figure 1-4 The tensioning member shown is connected to the inner surfaces of the upper piece 201 and the lower piece 202 by means of heat fusion, adhesive bonding or other methods. By setting multiple tensioning members of different heights, a mating part 270 and a transition part 280 are formed on the air bed body. For example, a tensioning member with the same height as the mating part 270 can be provided at the mating part 270 of the air bed body, and a tensioning member with the same height change as the transition part 280 can be provided at the transition part 280 of the air bed body; alternatively, a tensioning member can be provided only at the mating part 270 of the air bed body, and no tensioning member can be provided at the transition part 280 of the air bed body 200, so that the transition part 280 of the air bed body 200 is formed naturally after the air bed body 200 is inflated; or a tensioning member can be provided only at the transition part 280 of the air bed body, and no tensioning member can be provided at the mating part 270 of the air bed body 200, so that the mating part 270 of the air bed body 200 is formed naturally after the air bed body 200 is inflated. The number of mating parts 270 and transition parts 280 is not limited in this application. For example, the number of mating parts 270 can be 1, 2, 3, 4, etc., and the number of transition parts 280 can be 1, 2, 3, 4, etc. In some possible embodiments, depending on the shape or position of the vehicle seat, the mating parts 270 and transition parts 280 of the inflatable bed body 200 can be adaptively changed. For example, it may include only the mating parts 270 without the transition parts 280, or only the transition parts 280 without the mating parts 270, etc. This application does not limit this. In other possible embodiments, refer to... Figure 10cThe inflatable bed body 200 includes only one transition section 280, and the bottom surface of the transition section 280 is inclined. That is, along the length direction X, the bottom surface of the inflatable bed body 200 gradually slopes upward from the end near the front of the vehicle to the end near the rear of the vehicle, i.e., the height of the bottom surface of the inflatable bed body 200 gradually increases from the end near the front of the vehicle to the end near the rear of the vehicle. This application does not limit this; for example, the bottom surface of the inflatable bed body 200 may also gradually slope downward from the end near the front of the vehicle to the end near the rear of the vehicle, i.e., the height of the bottom surface of the inflatable bed body 200 gradually decreases from the end near the front of the vehicle to the end near the rear of the vehicle, and so on. In some other possible embodiments, the air mattress body 200 includes only a transition portion 280, and the top surface of the transition portion 280 is inclined (not shown in the figure). That is, along the length direction X, the top surface of the air mattress body 200 gradually slopes upward from the end near the front of the vehicle to the end near the rear of the vehicle, i.e., the height of the top surface of the air mattress body 200 gradually increases from the end near the front of the vehicle to the end near the rear of the vehicle. This application does not limit this; for example, the top surface of the air mattress body 200 may also gradually slope downward from the end near the front of the vehicle to the end near the rear of the vehicle, i.e., the height of the top surface of the air mattress body 200 gradually decreases from the end near the front of the vehicle to the end near the rear of the vehicle, and so on.

[0219] For example, when the internal filling of the air mattress body 200 is sponge, the difference between the highest and lowest height of the sponge is less than 30 cm. Preferably, when the internal filling of the air mattress body 200 is sponge, the difference between the highest and lowest height of the sponge is less than 15 cm.

[0220] This application discloses a scheme for installing a support structure at the bottom of a vehicle-mounted inflatable mattress. When a user needs to rest in the vehicle, the support structure at the bottom of the inflatable mattress can be placed above the driver's seat, passenger seat, and rear seats to keep the inflatable mattress in a horizontal or near-horizontal position for the user's rest. The vehicle-mounted inflatable mattress of this application can prevent the main body of the mattress from shaking during use, avoiding potential dangers and providing a better user experience.

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.
