The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0028] See also Figure 1-Figure 3 The utility model provides an airbag 100, which includes an airbag body 1, a first adsorption component 2 and a second adsorption component 3. The airbag body 1 is used to fill gas. The first adsorption component 2 and the second adsorption component 3 are fixed in the airbag body 1. When the airbag 100 shrinks, the first adsorption component 2 and the second adsorption component 3 are attracted to each other. When the airbag 100 is filled with gas, when the air pressure in the airbag 100 is less than a preset value, the first adsorption component 2 and the second adsorption component 3 are attracted to each other to prevent the airbag body 1 from deforming. When the air pressure in the airbag 100 exceeds the preset value, the first adsorption component 2 and the second adsorption component 3 are separated, 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.

[0029] In some embodiments, the preset value is the attraction value of the first attraction component and the second attraction component. Specifically, the attraction value is a negative pressure adsorption value, a magnetic adsorption value, an adhesion value or an electrostatic adsorption value, etc.

[0030] For the above-mentioned airbag body 1, please refer to Figure 2 and 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.

[0031] 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.

[0032] For the first adsorption component 2, please refer to Figure 3 The first adsorption component 2 is fixedly disposed on the first inner surface 13. The first adsorption component 2 is fixed to the first inner surface 13 by adhesive bonding or welding.

[0033] For the second adsorption component 3, please refer to Figure 3 The second adsorption component 3 is fixedly disposed on the second inner surface 14. The second adsorption component 3 is fixed to the second inner surface 14 by adhesive bonding or welding.

[0034] Among them, one of the first adsorption component 2 and the second adsorption component 3 is a suction cup, and the other of the first adsorption component 2 and the second adsorption component 3 has a smooth surface, so that when the air pressure in the airbag body 1 is less than the preset value, the suction cup is connected to the other of the first adsorption component 2 and the second adsorption component 3 through negative pressure adsorption. Furthermore, the other of the first adsorption component 2 and the second adsorption component 3 has a smooth surface, which is conducive to the suction cup to remove gas more thoroughly when it is sucked together, so that the vacuum area formed is more complete, the suction is more firm, and the situation that the preset value becomes smaller and the deformation speed of the airbag body 1 becomes slower, thereby reducing the situation that the explosive filling effect formed by the rapid deformation of the airbag body 1 is reduced. Furthermore, in some embodiments, the other of the first adsorption component 2 and the second adsorption component 3 is an acrylic plate, and the surface of the acrylic plate is smooth. The surface of the acrylic plate does not need to be processed twice to form a smooth surface, reducing the production and processing costs.

[0035] In some embodiments, in order to increase the force when the first adsorption component 2 and the second adsorption component 3 are separated and play a role of accumulating force, so as to speed up the deformation speed of the airbag body 1 and improve the explosive charging effect, the other of the first adsorption component 2 and the second adsorption component 3 is provided with a claw, and the claw is detachably connected to the suction cup. Specifically, the suction cup is provided with a card interface, and the claw can be detachably connected to the card interface. Further, one end of the claw is provided on the second adsorption component 3, and the other end of the claw is provided with a first guide surface, and the first guide surface is used to play a guiding role. Further, the suction cup is provided with a second guide surface, and the second guide surface is used to guide the claw when the suction cup and the other of the first adsorption component 2 and the second adsorption component 3 are sucked together.

[0036] It is understood that in some embodiments, see Figure 4 At least one of the first adsorption component 2 and the second adsorption component 3 is a magnet, and the other of the first adsorption component 2 and the second adsorption component 3 is a magnet or a ferromagnetic object, and the first adsorption component 2 and the second adsorption component 3 are connected by magnetic adsorption.

[0037] In some embodiments, in order to make the deformation speed of the airbag body 1 faster after the first adsorption component 2 and the second adsorption component 3 are separated, at least one of the two magnets is a magnet with variable magnetic poles. When the air cavity 11 is filled with gas until the air pressure in the air cavity 11 exceeds a preset value, the magnetic pole of the magnet with variable magnetic pole changes, thereby generating a repulsive force. Of course, both magnets can be magnets with variable magnetic poles. When the airbag body 1 needs to switch to rapid deformation, it is only necessary to adjust the magnetic pole of one of the magnets. The magnet with variable magnetic poles can specifically be an electromagnet or an electromagnet.

[0038] It can be understood that, in some embodiments, adhesive is provided on the side of the first adsorption component 2 facing the second adsorption component 3 and / or on the side of the second adsorption component 3 facing the first adsorption component 2, and the first adsorption component 2 and the second adsorption component 3 are connected by the adhesive.

[0039] It can be understood that, in some embodiments, the first adsorption component 2 and the second adsorption component 3 are both electrostatic tapes, and the first adsorption component 2 and the second adsorption component 3 are connected by electrical adsorption.

[0040] In an embodiment of the utility model, the airbag 100 includes an airbag body 1, a first adsorption component 2 and a second adsorption component 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 relatively along the main deformation direction X. The first adsorption component 2 is fixedly arranged on the first inner surface 13, and the second adsorption component 3 is fixedly arranged on the second inner surface 14. When the air pressure in the airbag 100 is less than a preset value, the first adsorption component 2 and the second adsorption component 3 are mutually attracted to prevent the airbag body 1 from deforming. When the air pressure in the airbag body 1 exceeds the preset value, the first adsorption component 2 and the second adsorption component 3 are separated to allow the airbag body 1 to deform rapidly. Since the airbag body 1 can deform rapidly to form an explosive filling effect, a beating effect is achieved to enhance the massage effect. Furthermore, the massage mode of the pneumatic massage system is increased to enhance the user experience.

[0041] 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 through the 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 structure and function of the air bag 100 can be referred to the above-mentioned embodiment, which will not be repeated here.

[0042] In some embodiments, the pneumatic massage system further includes a gas storage device, which is used to store gas, one end of which is connected to the valve assembly, and the other end of which is connected to the air pump. When the air bag 100 is filled with gas until the first adsorption component 2 and the second adsorption component 3 of the air bag 100 are suddenly separated, the volume of the air bag 100 suddenly increases, and the air pressure inside the air bag 100 decreases. 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.

[0043] In some embodiments, the gas storage device is an air storage bag 100 or an air storage tank.

[0044] The utility model further provides a seat, which includes the above-mentioned pneumatic massage system. The structure and function of the pneumatic massage system can be found in the above-mentioned embodiments, which will not be described in detail here.

[0045] It should be noted that the preferred embodiments of the utility model are given in the specification and drawings of the utility model, but the utility model can be implemented in many different forms and is not limited to the embodiments described in the specification. These embodiments are not used as additional restrictions on the content of the utility model.

In addition, the above-mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as the scope of the description of the utility model; further, for ordinary technicians in this field, they can be improved or transformed according to the above description, and all these improvements and transformations should belong to the scope of protection of the claims attached to the utility model.
