[0029] See also Figure 1-Figure 3 The utility model provides an airbag 100, which includes an airbag body 1, a first snap-fit ​​structure 2 and a second snap-fit ​​structure 3. The airbag body 1 is used for filling gas. The first snap-fit ​​structure 2 and the second snap-fit ​​structure 3 are fixed in the airbag body 1. When the airbag 100 is in a contracted state, the first snap-fit ​​structure 2 and the second snap-fit ​​structure 3 are snap-connected. When filling gas into the airbag 100, when the air pressure in the airbag body 1 is less than or equal to a preset value, the first snap-fit ​​structure 2 is snap-connected with the second snap-fit ​​structure 3 to prevent the airbag body 1 from deforming. When the air pressure in the airbag body 1 exceeds the preset value, the first snap-fit ​​structure 2 is separated from the second snap-fit ​​structure 3, so that the airbag body 1 is deformed quickly to form an explosive filling effect, thereby achieving a beating effect and improving the massage effect.

[0030] In some embodiments, the preset value is the force value required for the first buckle structure 2 and the second buckle structure 3 to separate.

[0031] For the above-mentioned airbag body 1, please refer to Figure 3 The airbag body 1 is provided with an air cavity 11, an air nozzle 12, a first inner surface 13 and a second inner surface 14. The air cavity 11 is a cavity with a variable volume, and the air cavity 11 is used to fill gas. The air nozzle 12 is connected to the air cavity 11. During operation, the airbag body 1 is expanded by filling gas into the air cavity 11 through the air nozzle 12, or the gas in the air cavity 11 is released outward through the air nozzle 12 to shrink the airbag body 1. The expansion and contraction state switching process of the airbag body 1 corresponds to the squeezing and loosening process of massage. The first inner surface 13 and the second inner surface 14 are arranged relatively along the main deformation direction X.

[0032] In some embodiments, the airbag body 1 is made of a weldable plastic material, and the weldable plastic material includes but is not limited to polycarbonate (PC), thermoplastic polyurethane elastomer (TPU), polyvinyl chloride (PVC) material, etc.

[0033] For the first buckle structure 2, please refer to Figure 3 The first buckle structure 2 is provided with a fixing plate 21 and at least two hooks 22.

The first hole portion 311 is located at one end close to the hook 22, and the diameter of the first hole portion 311 is smaller than the diameter of the second hole portion 312, so that the hook 22 is buckled at the connection between the first hole portion 311 and the second hole portion 312, thereby connecting the first buckle structure 2 and the second buckle structure 3. The hole wall of the first hole portion 311 close to one end of the hook 22 is provided with a second guide surface 3111, and the second guide surface 3111 is used to further guide the hook 22.

[0035] It can be understood that, in some embodiments, the structure of the connecting hole 31 is not limited to the above structure, and the connecting hole 31 can also be other structures. For example, the hole wall of the connecting hole 31 is provided with a receiving hole, and the receiving hole is located at one end close to the hook 22. The receiving hole is obtained by the depression of the hole wall of the connecting hole 31, and the receiving hole is set for the hook 22 so that the hook 22 is buckled in the receiving hole.

[0036] It is understandable that, in some embodiments, the second buckle structure 3 is not limited to the above structure, and the second buckle structure 3 can be other structures. For example, the second buckle structure 3 is not provided with the above connection hole 31, and the edge of the second buckle structure 3 is provided with a buckling portion, and when the first buckle structure 2 is connected with the second buckle structure 3, each hook 22 is buckled on the edge of the surface of the buckling portion away from the first buckle structure 2.

For example, the first snap-on structure 2 is provided with at least one hook 22, and the second snap-on structure 3 is not provided with the above-mentioned connecting hole 31, and the second snap-on structure 3 is provided with a groove, and the groove is provided corresponding to the hook 22. When the first snap-on structure 2 is connected with the second snap-on structure 3, the hook 22 is accommodated in the groove, and the hook 22 is buckled on the surface of the second snap-on structure 3 facing away from the first snap-on structure 2.

[0038] It can be understood that, in some embodiments, the first snap-in structure 2 and the second snap-in structure 3 are not limited to the above-mentioned structure, and the first snap-in structure 2 and the second snap-in structure 3 can be other structures. For example, the first snap-in structure 2 is not provided with the above-mentioned hook 22, and the first snap-in structure 2 is provided with a protrusion, and the protrusion is fixed to the surface of the fixing plate 21 away from the first inner surface 13. The second snap-in structure 3 is not provided with the above-mentioned connecting hole 31, the buckling portion and the recessed hole, and the second snap-in structure 3 is provided with a mounting hole, and the mounting hole is used to accommodate the protrusion, and the diameter of the mounting hole is smaller than the diameter of the protrusion. When the first snap-in structure 2 is connected to the second snap-in structure 3, the protrusion and the mounting hole are connected by interference fit.

[0039] In the embodiment of the utility model, the airbag 100 includes an airbag body 1, a first buckle structure 2 and a second buckle structure 3, the airbag body 1 is used to fill gas, the airbag body 1 includes a first inner surface 13 and a second inner surface 14 arranged opposite to each other along the main deformation direction, the first buckle structure 2 is arranged on the first inner surface 13, and the second buckle structure 3 is arranged on the second inner surface 14, wherein, when the air pressure in the airbag body 1 is less than or equal to a preset value, the first buckle structure 2 is buckled with the second buckle structure 3 to prevent the airbag body 1 from deforming, and when the air pressure in the airbag body 1 exceeds the preset value, the first buckle structure 2 is separated from the second buckle structure 3 to make the airbag body 1 deform rapidly. When the first buckle structure 2 and the second buckle structure 3 are suddenly separated under the action of gas, the airbag 100 is deformed rapidly under the action of gas to form an explosive charging effect, thereby achieving a thumping effect and improving the massage effect. Further, the massage method of the pneumatic massage system is increased to avoid the massage method being too single and improve the user experience.

[0040] The utility model also provides a pneumatic massage system, which can be a massage system used in car seats, high-speed rail seats, airline seats, home seats and other seats, or a massage system used in a car massage pad, or a massage system used in a mattress to indirectly or directly act on certain body parts of a sleeping user. The pneumatic massage system includes an air pump, a valve assembly, a controller and the above-mentioned air bag 100, the air pump is used to inflate or exhaust the air bag body 1 of the air bag 100 through an air path, the valve assembly is used to control the on-off of the air path between the air pump and the air bag 100, the controller is connected to the valve assembly, and the controller is used to control the opening and closing of the valve assembly.

The gas in the gas storage device can be quickly added to the air bag 100, so as to avoid the air pump's insufficient gas output and the inability to quickly add sufficient gas to the air bag 100, so as to enhance the explosive charging effect of the air bag 100, and further enhance the beating effect of the air bag 100.

[0042] In some embodiments, the gas storage device is a gas storage bag or a gas storage tank.
