[0042] As shown in Figure 1 , in a first aspect, the embodiments of the present application provide an air bag cushion 1000, which relates to the technical field of soft furniture and is mainly applied to a mattress to provide a comfortable surface for users to sleep or rest.

[0043] Of course, the air bag cushion 1000 can also be applied to other soft furniture, such as a sofa, a massage chair, a floor mat, etc., and the application scenarios of the air bag cushion 1000 are not specifically limited herein.

[0044] As shown in Figure 2 , Figure 3 and Figure 8 , the air bag cushion 1000 provided by the embodiments includes at least one sub-air bag cushion 100, each sub-air bag cushion 100 includes two plastic uptake layers 110 which are stacked, each plastic uptake layer 110 has a recess 111 formed by plastic uptake, the parts of the two plastic uptake layers 110 except the recess 111 are hot-melt connected, the recesses 111 of the two plastic uptake layers 110 are spliced to form a plurality of air bag groups 120, each air bag group 120 includes a plurality of air bag parts 121 having air bag cavities and a plurality of air passage parts 122 having air passages; in each air bag group 120, each air bag part 121 is connected with at least one adjacent air bag part 121 through the air passage part 122, so that each air bag cavity is communicated with at least one adjacent air bag cavity through the air passage.

[0045] Exemplarily, the number of the sub-air bag cushions 100 can be one, two, three, four, five, etc., and is not specifically limited herein.

[0046] It can be understood that in the air bag cushion 1000 provided by the embodiments, the two plastic uptake layers 110 which are formed with the recess 111 by the plastic uptake process are stacked and hot-melt connected, which is easy to form the air bag part 121 which is thinner in shape and higher, the thinner air bag part 121 can increase its arrangement density, and the higher air bag part 121 can increase its deformation space in the height direction, so that the air bag cushion 1000 can better support and fit the human body.

[0047] As shown in Figures 3 to 6 and Figure 8As shown, in one embodiment, the airbag cushion 1000 has a first direction X, a second direction Y and a third direction Z perpendicular to each other, two plastic uptake layers 110 are arranged in the third direction Z, each airbag part 121 includes two sub-airbag parts 1211 arranged oppositely in the third direction Z, each sub-airbag part 1211 includes a first bag body 12111 and a second bag body 12112 connected together, the first bag bodies 12111 of the two sub-airbag parts 1211 are connected together to jointly define the airbag cavity, the orthographic projection shape of each first bag body 12111 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is rectangular, and the orthographic projection shape of each second bag body 12112 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is semispherical. Such shape design makes each airbag part 121 have the characteristics of small force area and small volume, so that the airbag cushion 1000 feels more soft to the human body.

[0048] It should be noted that the orthographic projection shape of each first bag body 12111 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is rectangular, which means that the orthographic projection shape of each first bag body 12111 on a plane perpendicular to the first direction X is rectangular, and the orthographic projection shape of each first bag body 12111 on a plane perpendicular to the second direction Y is rectangular. The orthographic projection shape of each second bag body 12112 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is semispherical, which means that the orthographic projection shape of each second bag body 12112 on a plane perpendicular to the first direction X is semispherical, and the orthographic projection shape of each second bag body 12112 on a plane perpendicular to the second direction Y is semispherical.

[0049] As Figure 8 and Figures 10 to 13As shown, in another embodiment, the airbag cushion 1000 has a first direction X, a second direction Y and a third direction Z perpendicular to each other, two plastic uptake layers 110 are arranged in the third direction Z, each airbag part 121 includes two sub-airbag parts 1211 arranged oppositely in the third direction Z, each sub-airbag part 1211 includes a first bag body 12111 and a second bag body 12112 connected to each other, the first bag bodies 12111 of the two sub-airbag parts 1211 are connected to each other to jointly define the airbag cavity, and the orthographic projection shape of each first bag body 12111 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is a trapezoid. Further, each second bag body 12112 includes two first bag segments 121121 and a second bag segment 121122 connected between the two first bag segments 121121, the second bag segment 121122 and each first bag segment 121121 are connected to the first bag body 12111, the orthographic projection shape of each first bag segment 121121 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is a quarter sphere, and the orthographic projection shape of the second bag segment 121122 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is a rectangle. Such shape design makes each airbag part 121 have a large force-receiving area and a large volume, so that the airbag cushion 1000 has a more intense feeling to the human body.

[0050] It should be noted that the orthographic projection shape of each first bag body 12111 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is a trapezoid, which means that the orthographic projection shape of each first bag body 12111 on a plane perpendicular to the first direction X is a trapezoid, and the orthographic projection shape of each first bag body 12111 on a plane perpendicular to the second direction Y is a trapezoid. The orthographic projection shape of each first bag segment 121121 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is a quarter sphere, which means that the orthographic projection shape of each first bag segment 121121 on a plane perpendicular to the first direction X is a quarter sphere, and the orthographic projection shape of each first bag segment 121121 on a plane perpendicular to the second direction Y is a quarter sphere.

[0051] In addition, the orthographic projection shape of the second bag segment 121122 on a plane perpendicular to the first direction X and on a plane perpendicular to the second direction Y is a rectangle, which means that the orthographic projection shape of the second bag segment 121122 on a plane perpendicular to the first direction X is a rectangle, and the orthographic projection shape of the second bag segment 121122 on a plane perpendicular to the second direction Y is a rectangle.

[0052] As Figure 1 , Figure 7 and Figure 13As shown, in one embodiment, the airbag cushion 1000 has a third direction Z, the two plastic uptake layers 110 are stacked along the third direction Z, and the size of each airbag portion 121 in the third direction Z is H, which satisfies 5cm≤H≤14cm.

[0053] Exemplarily, H can be selected as any value in 5cm, 6cm, 7cm, 7.5cm, 8cm, 9cm, 10cm, 11cm, 13cm, 14cm or any range formed by any two of them, which is not specifically limited here.

[0054] It should be noted that the above H refers to the maximum size of the airbag portion 121 in the third direction Z after inflation, rather than the size change range of the airbag portion 121 when deformed.

[0055] It can be understood that when the third direction Z is a vertical direction, the size H of each airbag portion 121 in the third direction Z is the height of each airbag portion 121. By stacking and hot melting the two plastic uptake layers 110 formed with the recesses 111 using the plastic uptake process, it is easy to form the airbag portion 121 with a higher shape, so that the height of the airbag portion 121 is between 5cm and 14cm, so that the airbag cushion 1000 can better fit the curved structure of the human body, so as to reduce the generation of the suspended area between the human body and the airbag cushion 1000, and further improve the sleep quality.

[0056] As shown in Figure 8 and Figure 9 In one embodiment, each plastic uptake layer 110 includes a first plastic layer 112 and a second plastic layer 113, and the second plastic layer 113 is connected to the side of the first plastic layer 112 away from the airbag cavity.

[0057] It can be understood that based on the above structure, when the airbag cushion 1000 is made, the first plastic layer 112 and the second plastic layer 113 are first compounded to form the plastic uptake layer 110, then the plastic uptake process is used to form the recess 111 on each plastic uptake layer 110, and then the areas of the two plastic uptake layers 110 except the recess 111 are hot melted to connect, so that the recesses 111 of the two plastic uptake layers 110 are spliced to form the plurality of airbag groups 120.

[0058] Further, the first plastic layer 112 is one of a thermoplastic polyurethane layer (TPU), a polyurethane layer (PU), and a polyvinyl chloride layer (PVC), and the second plastic layer 113 is one of a polyester lycra cloth and a polyether lycra cloth.

[0059] It should be noted that the polyester Lycra fabric and the polyether Lycra fabric are two kinds of elastic fabrics containing Lycra (Spandex) component, and the main difference lies in the chemical structure and performance of the base fiber. Specifically, the polyester Lycra fabric is a fabric made of polyester fiber (Polyester, PET) as the main base fiber, blended or compounded Lycra. Polyester fiber is obtained by chemical synthesis, which has high strength and wear resistance. The polyether Lycra fabric is a fabric made of polyether-based polyurethane fiber or fiber containing polyether compounds combined with Lycra. The polyether-based Spandex contains polyether segments in the molecular structure, and has higher softness and hydrophilicity.

[0060] It can be understood that one of the thermoplastic polyurethane layer, the polyurethane layer and the polyvinyl layer is used as the first plastic layer 112, so that the blister layer 110 has good thermoplasticity, which is convenient for blister processing to form the recess 111. One of the polyester Lycra fabric and the polyether Lycra fabric is used as the second plastic layer 113, which can increase the structural strength of the air bag cushion 1000, prolong the service life of the air bag cushion 1000, and reduce the noise generated by the rebound of the air bag part 121, achieving the effect of noise reduction.

[0061] As shown in Figure 9 Further, each blister layer 110 further comprises an adhesive layer 114 disposed between the first plastic layer 112 and the second plastic layer 113 to bond the first plastic layer 112 and the second plastic layer 113, thereby realizing the compounding of the first plastic layer 112 and the second plastic layer 113.

[0062] Exemplarily, the adhesive layer 114 can be a glue layer, double-sided tape, etc., which is not specifically limited here.

[0063] As shown in Figure 3 In one embodiment, the air bag cushion 1000 comprises a plurality of sub-air bag cushions 100, and in each sub-air bag cushion 100, the portions of the two blister layers 110 except the recess 111 are heat-fused to form a connecting plate 130, and a plurality of air bag groups 120 are arranged on the connecting plate 130; the connecting plate 130 of each sub-air bag cushion 100 is detachably connected with the connecting plate 130 of at least one adjacent sub-air bag cushion 100, so that each sub-air bag cushion 100 is detachably connected with at least one adjacent sub-air bag cushion 100. In this way, the air bag cushion 1000 can be easily divided into a plurality of sub-air bag cushions 100, or the plurality of sub-air bag cushions 100 can be easily assembled into the air bag cushion 1000, thereby facilitating the factory packaging and logistics transportation of the air bag cushion 1000.

[0064] As shown in Figure 3 and Figure 4As shown, in one embodiment, at least one air bag part 121 in each air bag group 120 is provided with an air nozzle 123, which is used for the input and output of gas, i.e. the air nozzle 123 has a dual role of gas input and gas output. In this way, the air bag cushion 1000 can be dynamically adjusted by controlling the gas to meet the physical conditions and personal preferences of different users.

[0065] In summary, the process flow of the air bag cushion 1000 provided by the embodiment is as follows: 1. The first plastic layer 112 and the second plastic layer 113 are compounded into the blister layer 110 through the adhesive layer 114; 2. Each blister layer 110 is placed in a positive and negative pressure blister machine, and each part of the blister layer 110 is uniformly heated by a heating tube, and then placed in a mold for blistering. During the blistering process, the blister layer 110 and the mold are first sealed to form a recess 111 by vacuumizing treatment, and then the recess 111 is blown by a gas pipe to make the forming effect better; 3. The two blister layers 110 after blistering are placed in a high-frequency equipment, and are hot-melt connected by high-frequency voltage to make the two blister layers 110 compounded together to form a sub-air bag cushion 100.

[0066] In the second aspect, the embodiment of the present application further provides a mattress, which comprises the air bag cushion 1000 in any one of the embodiments of the first aspect.

[0067] It can be understood that, since the mattress provided by the embodiment has the air bag cushion 1000 in any one of the embodiments of the first aspect, it has all the beneficial effects of the air bag cushion 1000, which will not be described here.
