[0002] Pneumatic massage seats are designed according to ergonomics and feature a pneumatic massage system comprised of an air pump, air valves, and multiple air bags. The air pump supplies air, while the air valves control the inflation and deflation of each air bag, which in turn controls the expansion and contraction of each bag to achieve a massage effect, alleviating fatigue, improving comfort, and protecting the lumbar spine.

[0003] However, in the process of implementing the embodiments of the present invention, the inventors found that: currently, during the inflation process of the air bag, the air bag is gradually expanded by the continuous air supply of the air pump, and the process of the air bag expanding is relatively slow, so that the air bag can only achieve a supporting effect on the back of the passenger, and cannot achieve a pounding effect similar to human body massage, resulting in poor massage effect. Summary of the Invention

[0004] The embodiment of the present invention provides an air bag, a pneumatic massage system and a seat, aiming to solve the problem that a beating effect similar to that in human body massage cannot be achieved, resulting in poor massage effect.

[0006] Optionally, one of the first adsorption component and the second adsorption component is a suction cup, and the other of the first adsorption component and the second adsorption component has a smooth surface, so that when the air pressure in the airbag body is lower than a preset value, the suction cup is connected to the other of the first adsorption component and the second adsorption component by negative pressure adsorption.

When the air bag is deflated, the first adsorption component and the second adsorption component are attracted to each other. When the air bag is filled with gas, until the air pressure in the air bag exceeds a preset value, the first adsorption component and the second adsorption component separate, so that the air bag body produces rapid deformation, forming an explosive filling effect, thereby achieving a hammering effect and improving the massage effect.

[0026] For ease of understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this invention belongs. The terms used in this specification and in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0028] See also Figure 1-Figure 3 The present invention provides an air bag 100, which includes an air bag body 1, a first adsorption component 2 and a second adsorption component 3. The air bag body 1 is used to fill gas. The first adsorption component 2 and the second adsorption component 3 are fixed in the air bag body 1. When the air bag 100 shrinks, the first adsorption component 2 and the second adsorption component 3 are attracted to each other. When gas is filled into the air bag 100, when the air pressure in the air bag 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 air bag body 1 from deforming. When the air pressure in the air bag 100 exceeds the preset value, the first adsorption component 2 and the second adsorption component 3 are separated, so that the air bag body 1 is rapidly deformed, forming an explosive filling effect, thereby achieving a pounding effect and enhancing the massage effect.

[0029] In some embodiments, the preset value is an 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, an electrostatic adsorption value, or the like.

[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 variable-volume cavity used to be filled with gas. The air nozzle 12 is connected to the air cavity 11. During operation, the airbag body 1 is expanded by filling the air cavity 11 with gas through the air nozzle 12, or the gas in the air cavity 11 is released outward through the air nozzle 12, causing the airbag body 1 to contract. The process of switching between the expansion and contraction states of the airbag body 1 corresponds to the squeezing and releasing process of massage. The first inner surface 13 and the second inner surface 14 are arranged relative to each other along the main deformation direction X.

[0031] In some embodiments, the airbag body 1 is made of a weldable plastic material, including but not limited to polycarbonate (PC), thermoplastic polyurethane (TPU), polyvinyl chloride (PVC) and the like.

[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 a preset value, the suction cup and the other of the first adsorption component 2 and the second adsorption component 3 are connected by 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, thereby forming a more complete vacuum area and a more firm suction, reducing the situation where the preset value becomes smaller and the deformation speed of the airbag body 1 slows down, thereby reducing the situation where the explosive filling effect caused 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 undergo secondary processing to form a smooth surface, thereby reducing 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 to play a role of storing force, so that the deformation speed of the airbag body 1 becomes faster and the explosive charging effect is improved, 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 is detachably connected to the card interface. Furthermore, 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. Furthermore, 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 attracted.

[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 is understandable 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 present invention, 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 the gas. The airbag body 1 includes a first inner surface 13 and a second inner surface 14 arranged relative to each other 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 attracted to each other 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 pounding effect is achieved, thereby enhancing the massage effect. Furthermore, the massage method of the pneumatic massage system is increased to enhance the user experience.

[0041] The present invention also provides a pneumatic massage system, which can be used in car seats, high-speed rail seats, airline seats, home seats, and the like; in vehicle massage cushions; or in mattresses, indirectly or directly affecting certain body parts of a sleeping user. The pneumatic massage system includes an air pump, a valve assembly, a controller, and the aforementioned air bag 100. The air pump is used to inflate or deflat the air bag body 1 through an air circuit; the valve assembly is used to control the opening and closing of the air circuit between the air pump and the air bag 100; and the controller is connected to the valve assembly and is used to control the opening and closing of the valve assembly. The structure and function of the air bag 100 can be found in the aforementioned embodiments and will not be detailed here.

[0042] In some embodiments, the pneumatic massage system further includes a gas storage device for storing gas, one end of the gas storage device being connected to the valve assembly, and the other end of the gas storage device being 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 suddenly separate, 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 replenished into the air bag 100, avoiding the situation where the air pump's air output is insufficient and sufficient gas cannot be quickly replenished into the air bag 100, thereby improving the explosive charging effect of the air bag 100 and further improving 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 present invention 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 and will not be described in detail here.

These embodiments are not intended to be additional limitations on the content of the present invention.

In addition, the above-mentioned technical features can be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of the present invention.
