[0034] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] like Figures 1 to 6As shown, an airbag assembly of this embodiment includes: multiple airbags 10, each airbag 10 includes multiple stacked sub-airbags and a connecting portion 11. The connecting portion 11 is provided between adjacent sub-airbags to connect the sub-airbags. When the airbag assembly is placed horizontally, the projections of adjacent airbags 10 on a vertical plane have overlapping portions. The airbags 10 extend from a first side of the airbag 10 to a second side of the airbag 10. The sub-airbag at the top of the airbag 10 is connected to the sub-airbag of the adjacent airbag 10.

[0036] In the technical solution of this application, each airbag 10 of the airbag assembly 100 is composed of multiple stacked sub-airbags. This allows the airbag's operating height to be increased without increasing its diameter. This structure effectively meets the human body's requirements for height during massage. The sub-airbag at the top of the airbag is connected to the sub-airbags of adjacent airbags, making it less likely to misalign, thereby improving the overall, stable, and consistent massage experience. The technical solution of this embodiment effectively solves the problems of poor overall, stability, and consistency in airbag assemblies in the prior art.

[0037] It should be noted that the connecting portion 11 of this embodiment has a predetermined length, which facilitates the installation of the airbag clamping structure. The sub-airbags in the airbag are bonded together or integrally formed, rather than simply placing the upper sub-airbag on the lower sub-airbag. The bottom surface of the first sub-airbag 12 at the bottom of the airbag has an airbag connector. This connector is flat and extends in the direction of the airbag assembly's extension, which can be customized depending on the situation. The flat structure ensures that the thickness of the airbag connector does not cause discomfort to the human body. If the airbag connector is thicker, a groove can be made in the mattress to accommodate it. In the technical solution of this embodiment, multiple airbag connectors are provided, each spaced apart and extending in the direction of the airbag assembly's extension. This makes the airbag assembly 100 more secure and consistent, and prevents the airbag from detaching. In another embodiment, the airbag connector is a closed rectangular shape, which improves the integrity and stability of the airbag assembly 100. Alternatively, the airbag connector can be a rectangular shape with a hollowed-out structure. This structure allows the airbag assembly 100 to be more material-efficient and lighter. It should be noted that the hollowed-out structure can take various forms, such as a rectangular shape with a large hollowed-out center, giving the airbag connector a square shape. The airbag connector is located on the same side of the airbag assembly 100. This facilitates the mating of the airbag assembly 100 with the mattress body. For example, if the airbag connector is located at the bottom of the airbag assembly 100, the airbag assembly 100 can be installed by simply accessing one side of the assembly 100. There are various ways to connect the airbag 10 and the airbag connector: adhesive bonding; tying the airbag 10 and the airbag connector with a cable tie; tying the airbag 10 and the airbag connector with a flexible rope; welding the airbag 10 and the airbag connector; zippering the airbag 10 and the airbag connector; or any combination of the above connection methods. It should be noted that the airbag assembly 100 can also be directly riveted to the mattress body, such as Figure 5 shown.

[0038] like Figures 1 to 4As shown, the multiple sub-airbags include a first sub-airbag 12 and a second sub-airbag 13, the connecting portion 11 is arranged between the first sub-airbag 12 and the second sub-airbag 13, and the first side of the rear airbag is clamped between the first sub-airbag 12 and the second sub-airbag 13 of the front airbag. The structure in which the first side of the rear airbag is clamped between the first sub-airbag 12 and the second sub-airbag 13 of the front airbag makes it difficult for the airbags 10 of the airbag assembly 100 to detach. That is, part of the upper surface of the rear airbag 10 is in contact with the lower surface of the second sub-airbag 13 of the front airbag, and part of the lower surface of the rear airbag 10 is in contact with the upper surface of the first sub-airbag 12 of the front airbag. The sub-airbags of the same airbag 10 are connected. This structure is easy to inflate, and there is no need to inflate each sub-airbag separately. Moreover, this avoids the need for a large number of inflation ports, reducing the probability of damage. The inflation port of the airbag 10 is arranged on a side of the first sub-airbag 12 away from the second sub-airbag 13 . When the airbag 10 is not inflated, the first sub-airbag 12 and the second sub-airbag 13 overlap to form a rectangle.

[0039] In the technical solution of this embodiment, the rear second sub-airbag 13 is connected to the front second sub-airbag 13. This makes it more difficult for the airbag assembly 100 to be disengaged when subjected to external force.

[0040] In the technical solution of this embodiment, adjacent second sub-airbags 13 are fixedly connected, and / or adjacent second sub-airbags 13 are connected relatively movably using a connector. In actual use, adjacent second sub-airbags 13 can be fixedly connected, adjacent second sub-airbags 13 can be connected relatively movably using a connector, or the same airbag assembly 100 can have adjacent second sub-airbags 13 fixedly connected and adjacent second sub-airbags 13 connected relatively movably using a connector.

[0041] In the technical solution of this embodiment, when adjacent second sub-airbags 13 are relatively movably connected, the connection methods between the adjacent second sub-airbags 13 include cable tie connection, rivet connection, and rope binding connection. Because the airbag assembly 100 has an inflated state and a non-inflated state, the relative position of the sub-airbags changes. The relatively movably connected adjacent second sub-airbags 13 precisely meet the requirements of this relative position change.

[0042] like Figure 1 and Figure 3 As shown, in the technical solution of this embodiment, each second sub-airbag 13 has a connecting through-hole 131, through which the connecting member passes. The provision of connecting through-hole 131 facilitates connection, simplifies operation, and reduces installation costs. It should be noted that each sub-airbag in this embodiment includes a sub-airbag body and a skirt located at the edge of each sub-airbag. The connecting through-hole 131 is located at the skirt to prevent damage to the sub-airbag.

[0043] like Figure 1 As shown, in the technical solution of this embodiment, the connecting through hole 131 is located on the second side of the second sub-airbag 13. The connecting through hole 131 is located on the skirt of the second side of the second sub-airbag 13, which facilitates the connection of the second sub-airbag 13.

[0044] like Figure 1 As shown, in the technical solution of this embodiment, each second sub-airbag 13 has multiple connecting through-holes 131, arranged along both sides of the airbag 10 in the direction from the first side to the second side. This structure facilitates the connection of adjacent second sub-airbags 13 and ensures balanced force on the airbag 10. The multiple connecting through-holes 131 are located on both sides of the extension direction of the airbag assembly 100, so that the connecting through-holes 131 are located on the side edges of the second sub-airbag 13. This structure prevents the airbag 10 from being lifted or misplaced from the edge.

[0045] like Figure 1 As shown, in the technical solution of this embodiment, each second sub-airbag 13 also has a matching through-hole 132. A connecting member passes through the connecting through-hole 131 and the matching through-hole 132 to connect the second sub-airbags 13. The matching form of the connecting through-hole 131 and the matching through-hole 132 makes the connection between the second sub-airbags relatively convenient.

[0046] like Figure 1 As shown, in the technical solution of this embodiment, there are multiple mating through holes 132, and the multiple mating through holes 132 are respectively located between the first side of the airbag 10 and the second side of the airbag 10, and are located on both sides of the extending direction from the first side of the airbag 10 to the second side of the airbag 10. This makes it easier to mate the mating through holes 132 with the connecting through holes 131, and the mating through holes 132 and the connecting through holes 131 will not damage the airbag body.

[0047] In the technical solution of this embodiment, there are multiple matching through holes 132 on each side, so that the connection positions of two adjacent second sub-airbags 13 can be adjusted as needed to ensure that the adjacent airbags 10 are in the best matching state.

[0048] In the technical solution of this embodiment (not shown in the figures), when rivets are used for connection, the connecting through-hole 131 is an elongated hole extending from the first side of the airbag 10 to the second side of the airbag 10. The connecting through-hole 131 is an elongated hole extending from the first side of the airbag 10 to the second side of the airbag 10. This allows adjacent second sub-airbags 13 to move relative to each other along the direction from the first side of the airbag 10 to the second side of the airbag 10, and forms a limit in other directions. It should be noted that when rivets are used for connection, the length of the rivet's polished rod is greater than the sum of the wall thicknesses of the two second sub-airbags, and the width of the elongated hole is compatible with the diameter of the rivet. In this way, the second sub-airbags 13 cannot move in the left-right direction and can be relatively unique in the front-back direction. The rivet in this embodiment can be made of metal or non-metallic material, such as non-metallic materials such as rubber, silicone, etc. As other embodiments, it is also possible for the matching through-hole 132 to be an elongated hole, or it is also possible for both the connecting through-hole 131 and the matching through-hole 132 to be elongated holes.

[0049] As another embodiment, adjacent second sub-airbags 13 may also be fixedly connected, including but not limited to the following connection methods: adhesive connection, sewing connection, fastener connection, and Velcro connection.

[0050] Adjacent air bags are clamped and overlapped.

[0051] In the technical solution of this embodiment, the side of the second sub-airbag 13 away from the first sub-airbag 12 has an arc-shaped surface. The use of a smooth arc-shaped transition can make the human body feel better. Specifically, the second sub-airbag 13 gradually shrinks and becomes thinner from a certain position in the middle to the first side of the second sub-airbag 13, and the second sub-airbag 13 gradually shrinks and becomes thinner from a corresponding position in the middle of the second sub-airbag 13 to the second side of the second sub-airbag 13. The projected area of the first sub-airbag 12 in the vertical direction is equal to the projected area of the second sub-airbag 13 in the vertical direction. The area of the first sub-airbag 12 is the same as the area of the second sub-airbag 13. Such a structure has strong adaptability. Generally speaking, it can meet both the requirements of stability and the needs of pushing and stroking. As another possible implementation, the vertical projection area of the first sub-airbag 12 is larger than the vertical projection area of the second sub-airbag 13, that is, the area of the lower sub-airbag is larger. Such an airbag is more stable, that is, the first sub-airbag 12 is set to be larger than the second sub-airbag 13, so that the bottom support of the airbag is stable, and the top airbag is smaller at this time, which will give the human body a greater pressure, and the experienced pushing and stroking force is greater. Other implementations can also be that the vertical projection area of the first sub-airbag 12 is smaller than the vertical projection area of the second sub-airbag 13. Such a structure makes the pushing and stroking area of the airbag larger. Setting the first sub-airbag 12 to be smaller than the second sub-airbag 13 can make the bottom airbag form a seesaw-like structure. At this time, when the human body lies on top of the airbag, the airbag can move together in one direction according to the body position adjustment.

[0052] like Figure 1 As shown, in the technical solution of this embodiment, the length from the connecting portion 11 to the first side of the airbag 10 accounts for 1 / 8 to 1 / 2 of the length from the first side of the airbag 10 to the second side of the airbag 10. This makes the airbag 10 more stable when assembled. For example, when the airbags 10 are clamped together, the mating area is larger. Specifically, the length from the connecting portion 11 to the second side of the airbag 10 accounts for 1 / 4 to 1 / 3 of the length from the first side of the airbag 10 to the second side of the airbag 10.

[0053] like Figure 1As shown, in the technical solution of this embodiment, the connecting portion 11 is a single connecting pipe or multiple connecting pipes. This structure is convenient. The connecting portion 11, the first sub-airbag 12, and the second sub-airbag 13 are made of the same material. In this embodiment, they are an integrally molded structure. Of course, the connecting portion 11, the first sub-airbag 12, and the second sub-airbag 13 can also be made of different materials, or even different colors to distinguish them, thereby distinguishing functional areas by color. In the technical solution of this embodiment, the first sub-airbag 12, the second sub-airbag 13, and the connecting portion 11 can be made of TPU (thermoplastic polyurethane elastomer rubber) or rubber. When the connecting portion 11 is a single connecting pipe, the connecting pipe is equidistant from the left and right sides of the airbag. This structure ensures that the force applied to the airbag 10 is relatively uniform. The single pipe arrangement can be configured so that the connecting pipe runs from the left side of the airbag to the right side of the airbag. This structure makes the connecting pipe structure relatively strong, allows the airbag to withstand relatively large forces, and applies force more evenly, making the connecting pipe less prone to clogging. For example, when a human body is pressed on top of the airbag 10, due to the effect of pressure, the connecting pipeline is prone to blockage, and a higher gas pressure needs to be provided. Of course, a pipeline can also be set up in such a way that the distance between a connecting pipe and the left side of the airbag is the same as the distance between the connecting pipe and the right side of the airbag, so that the force on the airbag is balanced. It should be noted that when the distance between a connecting pipe and the left side of the airbag and the right side of the airbag is large, the gap at the edge of the container is large, and the comfort level will be reduced. The shape of a pipeline is similar to a rectangle. The first sub-airbag 12 and the second sub-airbag 13 are also similar to a rectangle when there is no gas. When the connecting part 11 is a plurality of connecting pipelines, the plurality of connecting pipes are evenly spaced in the direction from the left side of the airbag to the right side of the airbag. The airbag of the above structure is more evenly stressed.

[0054] This application also provides a mattress. The mattress includes an airbag assembly 100, which is the aforementioned airbag assembly 100. Such a mattress provides more consistent massage, better integrity, and greater stability. Specifically, the mattress includes a mattress body, to which the airbag assembly 100 is connected.

[0055] The present application also provides a bed. The bed includes a mattress, which is the aforementioned mattress. The bed of the present application has good consistency, stability, and integrity in terms of massage and stroking.
