Detailed Implementation

[0032] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0033] In the description of this application, the terms "center", "longitudinal", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] Furthermore, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium. Moreover, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this application, the terms "first," "second," etc., are used to distinguish different objects and should not be construed as indicating or implying a specific order or hierarchy, or implicitly specifying the number of technical features indicated. Therefore, a feature marked "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0036] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] In the description of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering. For example, if the angle between two directions is 80° to 90°, the two directions can be considered perpendicular; if the angle between two directions is 0° to 10°, the two directions can be considered parallel.

[0038] Airbag mattresses, filled with gas to form a support structure, provide a comfortable surface for sleep and rest. However, current airbag mattresses are one-piece structures; if an airbag in one area is damaged, the entire mattress needs to be replaced, making repairs difficult. Furthermore, larger airbag mattresses are inconvenient for packaging and shipping.

[0039] To solve the above technical problems, such as Figure 1 and Figure 6 As shown, in a first aspect, embodiments of this application provide an airbag cushion 1000, which relates to the field of upholstered furniture technology and is mainly used in mattresses to provide users with a comfortable surface for sleeping or resting.

[0040] Of course, the Airbag Cushion 1000 can also be applied to other soft furniture, such as sofas, massage chairs, floor mats, etc. No specific restrictions are placed on the application scenarios of the Airbag Cushion 1000 here.

[0041] like Figures 1 to 3 As shown, the airbag cushion 1000 provided in this embodiment includes a plurality of sub-airbag cushions 100 and at least one detachable component 200.

[0042] Each sub-airbag cushion 100 includes a connecting plate 120 and a plurality of airbags 111 disposed on the connecting plate 120. The edges of the connecting plates 120 of two adjacent sub-airbag cushions 100 overlap. Each sub-airbag cushion 100 has a connecting hole 121 on its edge, which penetrates the connecting plate 120. Each detachable component 200 is disposed through the connecting hole 121 of two adjacent connecting plates 120, so that two adjacent sub-airbag cushions 100 can be detachably connected.

[0043] It is understood that the airbag cushion 1000 provided in this embodiment includes multiple sub-airbag cushions 100. Each sub-airbag cushion 100 includes a connecting plate 120 and multiple airbags 111 disposed on the connecting plate 120. The edges of the connecting plates 120 of adjacent sub-airbag cushions 100 overlap, and each sub-airbag cushion 100's connecting plate 120 edge is provided with a through connection hole 121. Furthermore, the airbag cushion 1000 also includes at least one detachable component 200. Each detachable component 200 is respectively disposed through the connection holes 121 of two adjacent connecting plates 120, allowing adjacent sub-airbag cushions 100 to be detachably connected. Thus, when any airbag 111 of a sub-airbag cushion 100 is damaged, only that sub-airbag cushion 100 needs to be disassembled, without replacing the entire airbag cushion 1000. This reduces the maintenance difficulty of the airbag cushion 1000, making its maintenance more convenient and cost-effective.

[0044] Furthermore, this detachable design allows the airbag cushion 1000 to be easily disassembled into multiple sub-airbag cushions 100, or multiple sub-airbag cushions 100 to be easily assembled into the airbag cushion 1000, thereby facilitating the factory packaging and logistics transportation of the airbag cushion 1000.

[0045] like Figures 2 to 5 As shown, in one embodiment, the connecting holes 121 of two adjacent connecting plates 120 are arranged opposite to each other. The detachable part 200 includes a male buckle 210 and a female buckle 220. The female buckle 220 is provided with a limiting part 221. The male buckle 210 includes a top cap part 211, a through part 212 and an elastic snap-fit ​​part 213. The through part 212 is connected to the top cap part 211 and the elastic snap-fit ​​part 213 respectively. The through part 212 is provided to pass through the connecting holes 121 of two adjacent connecting plates 120 respectively. The elastic snap-fit ​​part 213 snaps with the limiting part 221.

[0046] Understandably, by engaging the elastic snap-fit ​​portion 213 of the male snap-fit ​​210 with the limiting portion 221 of the female snap-fit ​​220, the male snap-fit ​​210 and the female snap-fit ​​220 can be easily joined together to assemble two adjacent sub-airbag cushions 100 together, and can also be easily separated to disassemble two adjacent sub-airbag cushions 100, thereby reducing the maintenance difficulty of the airbag cushion 1000 and facilitating factory packaging and logistics transportation.

[0047] Furthermore, the through part 212 is a cylinder, and the connecting hole 121 is a circular hole, with the cylinder and the circular hole having a clearance fit.

[0048] It is understandable that by using a cylinder as the through part 212 and a circular hole as the connecting hole 121, the two work together to effectively limit the relative movement of two adjacent sub-airbag cushions 100, making the structure of the airbag cushion 1000 more stable and reliable.

[0049] Of course, in the above embodiment, the through part 212 can also be an elliptical body and the connecting hole 121 can be an elliptical hole. There are no specific restrictions on the types of the through part 212 and the connecting hole 121.

[0050] like Figure 4 and Figure 5 As shown, the elastic snap-fit ​​portion 213 further includes a first snap-fit ​​2131 and a second snap-fit ​​2132 spaced apart. The first snap-fit ​​2131 and the second snap-fit ​​2132 are respectively connected to the through portion 212. The limiting portion 221 includes a first snap-fit ​​hole 2211 and a second snap-fit ​​hole 2212 that are connected. The first snap-fit ​​2131 is disposed through the first snap-fit ​​hole 2211 and engages with the second snap-fit ​​hole 2212. The second snap-fit ​​2132 is disposed through the first snap-fit ​​hole 2211 and engages with the second snap-fit ​​hole 2212. In this way, the snap-fit ​​between the male snap-fit ​​210 and the female snap-fit ​​220 is realized, so that the male snap-fit ​​210 and the female snap-fit ​​220 can be easily joined or easily separated, thereby facilitating the assembly and disassembly of two adjacent sub-airbag cushions 100.

[0051] Of course, in the above embodiment, the elastic snap-fit ​​part 213 may also include a spring and a steel ball, with a mounting hole provided on the outer periphery of the through part 212. The spring is connected between the bottom wall of the mounting hole and the steel ball, and the steel ball is movably disposed at the mounting hole. The limiting part 221 is a groove that mates with the steel ball. Under the elastic extension and contraction of the spring, the steel ball can be snapped into the groove or slide out of the groove, thus achieving the snap-fit ​​between the male buckle 210 and the female buckle 220. No specific limitations are made on the structure of the elastic snap-fit ​​part 213 and the limiting part 221 here.

[0052] like Figures 6 to 8 As shown, in another embodiment, the connecting holes 121 of two adjacent connecting plates 120 are staggered, and the detachable part 200 is a cable tie 230.

[0053] It is understandable that by using cable ties 230 to pass through the connection holes 121 of two adjacent connecting plates 120, the two adjacent sub-airbag pads 100 can also be detachably connected. That is, the cable ties 230 can be used to easily assemble or separate the two adjacent sub-airbag pads 100, thereby reducing the maintenance difficulty of the airbag pad 1000 and facilitating factory packaging and logistics transportation. No specific limitations are made regarding the structure of the detachable component 200.

[0054] Furthermore, the connecting hole 121 is an elliptical hole, and the direction of the major axis of the elliptical hole (i.e. the straight line direction where the longest diameter on the ellipse is located) is parallel to the width direction of the cable tie 230.

[0055] It is understandable that by using an elliptical hole as the connecting hole 121, and making the major axis of the elliptical hole parallel to the width direction of the cable tie 230, the gap between the cable tie 230 and the hole wall of the elliptical hole can be reduced, thereby effectively restricting the relative movement of two adjacent sub-airbag pads 100.

[0056] Of course, in the above embodiments, the connecting hole 121 can also be a rectangular hole, and the length direction of the rectangular hole (i.e. the length direction of the rectangle) is parallel to the width direction of the cable tie 230. There is no specific limitation on the type of connecting hole 121 here.

[0057] like Figure 7 and Figure 8 As shown, in one embodiment, the edge of the connecting plate 120 of each sub-airbag cushion 100 is provided with a stepped structure 122. The stepped structure 122 includes a first stepped surface 1221 and a second stepped surface 1222 connected to each other. The first stepped surface 1221 and the second stepped surface 1222 are perpendicular to each other. In the connecting plates 120 of two adjacent sub-airbag cushions 100, the first stepped surface 1221 of one connecting plate 120 abuts against the first stepped surface 1221 of the other connecting plate 120, and the second stepped surface 1222 of one connecting plate 120 abuts against the second stepped surface 1222 of the other connecting plate 120.

[0058] It is understandable that the abutting fit between the stepped structures 122 of the two adjacent connecting plates 120 can not only reduce the possibility of relative movement between the two adjacent sub-airbag pads 100, thereby increasing the stability of the airbag pad 1000, but also reduce the height difference after the two adjacent sub-airbag pads 100 are assembled together, making the entire airbag pad 1000 more flat after multiple sub-airbag pads 100 are assembled into the airbag pad 1000.

[0059] It should be noted that the design of the step structure 122 described above is applicable to both embodiments where the detachable part 200 is a cable tie 230 and embodiments where the detachable part 200 includes a male buckle 210 and a female buckle 220. No specific limitations are made on the application scenarios of the step structure 122 here.

[0060] like Figure 2 and Figure 7 As shown, in one embodiment, the airbag cushion 1000 includes a plurality of detachable parts 200. Each sub-airbag cushion 100 has a plurality of connection holes 121 on its connecting plate 120. Two adjacent connection holes 121 are spaced apart, meaning that two adjacent sub-airbag cushions 100 can be connected by a plurality of detachable parts 200. This improves the reliability and stability of the connection, thereby extending the service life of the airbag cushion 1000.

[0061] like Figure 6 and Figure 7 As shown, in one embodiment, each sub-airbag cushion 100 includes a plurality of airbag groups 110, which are spaced apart on the connecting plate 120. Each airbag group 110 includes a plurality of airbags 111. In each airbag group 110, each airbag 111 is connected to at least one adjacent airbag 111 to achieve communication between the plurality of airbags 111 in each airbag group 110. At least one airbag 111 in each airbag group 110 is provided with a nozzle 112 for inputting and outputting gas.

[0062] It is understood that by setting multiple airbag groups 110, each airbag group 110 including multiple airbags 111, that is, each airbag group 110 is set independently, so that the gas between two adjacent airbag groups 110 does not affect each other; at the same time, each airbag 111 is connected to at least one adjacent airbag 111, so as to realize the communication between the multiple airbags 111 in each airbag group 110. At least one airbag 111 in each airbag group 110 is provided with a nozzle 112 for inputting and outputting gas, that is, the nozzle 112 has the dual function of air intake and air exhaust. In this way, it is convenient to control the gas, for example, the airbag 111 inflates when gas is input and the airbag 111 contracts when gas is output, thereby realizing the dynamic adjustment of the airbag pad 1000 to meet the different physical conditions and personal preferences of different users.

[0063] Furthermore, the airbag cushion 1000 also includes multiple bidirectional air pumps, each bidirectional air pump being connected to an air nozzle 112, and the bidirectional air pumps have the function of both inflating and deflating.

[0064] It should be noted that the airbag cushion 1000 can be manufactured using the following process: 1. The first plastic layer and the second plastic layer are bonded together to form a vacuum-formed layer through an adhesive layer; 2. Each vacuum-formed layer is placed in a positive and negative pressure vacuum forming machine, and each part of the vacuum-formed layer is heated evenly through a heating tube. Then, it is placed in a mold for vacuum forming. During vacuum forming, the vacuum-formed layer and the mold are first sealed, and a vacuum treatment is performed to form a recessed part. Then, air is blown into the recessed part through an air tube to improve the forming effect; 3. The two vacuum-formed layers are placed in a high-frequency equipment and heat-fused together through high-frequency voltage, so that the two vacuum-formed layers are bonded together to form a sub-airbag cushion 100. After bonding, the recessed parts of the two vacuum-formed layers are spliced ​​together to form multiple airbag groups 110.

[0065] For example, the first plastic layer is one of thermoplastic polyurethane (TPU), polyurethane (PU), and polyethylene (PVC) base layer, and the second plastic layer is one of polyester Lycra and polyether Lycra. The adhesive layer is an adhesive layer, double-sided adhesive layer, etc., and is not specifically limited here.

[0066] It's important to note that polyester Lycra and polyether Lycra are two types of elastic fabrics containing Lycra (spandex), differing primarily in the chemical structure and properties of their base fibers. Specifically, polyester Lycra is made by blending or combining polyester fiber (PET) with Lycra as the main base fiber. Polyester fiber is chemically synthesized and possesses high strength and abrasion resistance. Polyether Lycra, on the other hand, is made by combining Lycra with polyether-based polyurethane fiber (Polyether-based Spandex) or fibers containing polyether compounds. Polyether-based spandex contains polyether segments in its molecular structure, resulting in greater softness and hydrophilicity.

[0067] Understandably, using one of the following as the first plastic layer—a thermoplastic polyurethane layer, a polyurethane layer, and a polyethylene base layer—gives the vacuum forming layer good thermoplasticity, facilitating vacuum forming to create the recessed area. Using one of the following as the second plastic layer—polyester Lycra or polyether Lycra—increases the structural strength of the airbag cushion, extends its service life, and reduces noise generated by the airbag's rebound, achieving a noise reduction effect.

[0068] Secondly, embodiments of this application also provide a mattress, including the airbag cushion 1000 in any of the embodiments of the first aspect described above.

[0069] It is understood that since the mattress provided in this embodiment has the airbag cushion 1000 in any of the embodiments of the first aspect, it has all the beneficial effects of the airbag cushion 1000, which will not be described in detail here.
