CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The application claims priority of Chinese patent application CN2025200700360, filed on Jan. 10, 2025, which is incorporated herein by reference in its entireties.TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of air cushions, and in particular to a silica gel airbag air cushion.BACKGROUND

[0003] An airbag air cushion is an air cushion product with an airbag structure. The airbag air cushion is loved by more and more consumers due to its advantages of light weight, good comfortability and the like.

[0004] At present, there are mainly two kinds of airbag air cushions on the market: the first one is an airbag air cushion provided with an inflation device. When the airbag air cushion leaks due to long-term use, the inflation device can be used to restore an airbag, but this kind of airbag air cushion has a complex structure, heavy weight and high production cost. The second one is an airbag air cushion without an inflation device. This kind of airbag air cushion is often made of a material with good air tightness so as to reduce the leakage of gas in an internal airbag and prolong the service life of the airbag air cushion. However, during the use of the airbag air cushion, there will still be air leakage in the airbag, and the airbag will lose its rebound function when the airbag deflates due to air leakage.

[0005] Based on this, the present disclosure provides an airbag air cushion with low cost and having long service life of an airbag.SUMMARY

[0006] The present disclosure provides a silica gel airbag air cushion, so as to solve the technical problem that the existing airbag air cushion is provided with an inflation device to cause complex structure, heavy weight and high production cost, or is not provided with an inflation device to cause an airbag to lose a rebound function after air leakage.

[0007] To solve the above technical problem, the present disclosure adopts the following technical solution:

[0008] a silica gel airbag air cushion includes a substrate and a plurality of airbags arranged on the substrate, where the plurality of airbags are arranged at intervals; at least part of each of the airbags protrudes from the substrate; a hollow airbag cavity is formed in each of the airbags; any two airbag cavities do not communicate with each other; and

[0009] in at least one airbag cavity, the height dimension of the airbag cavity is greater than the radial dimension of the airbag cavity.

[0010] In one of the embodiments, each of the airbags includes a first top part, a middle part and a second top part which are connected sequentially, the middle part is connected to the substrate, the first top part and the second top part are respectively connected to two opposite sides of the middle part, and the first top part and the second top part respectively protrude from two opposite sides of the substrate; and

[0011] each of the airbag cavities comprises a first cavity corresponding to the first top part, a middle cavity corresponding to the middle part and a second cavity corresponding to the second top part.

[0012] In one of the embodiments, the middle part is cylindrical, the first top part and the second top part are semi-spherical, and bag walls of the first top part and the second top part are tangent to a bag wall of the middle part.

[0013] In one of the embodiments, the middle part includes a protruding part protruding from the substrate, the protruding part is connected to the first top part or the second top part, and an extending direction of the protruding part is perpendicular to an extending direction of the substrate.

[0014] In one of the embodiments, the first top part and / or the second top part are / is provided with a protruding point structure, and the protruding point structure protrudes from an outer surface of the first top part or the second top part.

[0015] In one of the embodiments, the protruding point structure and the first top part or the second top part are integrally formed.

[0016] In one of the embodiments, the protruding point structure includes a central protruding point and a plurality of edge protruding points arranged around the central protruding point, the central protruding point is located at a largest end or a smallest end of the first top part or the second top part in a height direction, and the edge protruding points are located between the central protruding point and the substrate.

[0017] In one of the embodiments, the volume of the central protruding point is greater than the volume of the edge protruding points.

[0018] In one of the embodiments, the silica gel airbag air cushion further includes a protruding edge, where the protruding edge is arranged at an edge of the substrate and extends continuously in a circumferential direction of the substrate, and at least part of the protruding edge protrudes from the substrate.

[0020] According to the above technical solution, the embodiments of the present disclosure at least have the following advantages and positive effects:

[0021] in the silica gel airbag air cushion of the embodiments of the present disclosure, the airbags are made of a silica gel material with good air permeability. The airbags will leak slowly after being compressed, and the airbags will deform slowly. After the pressure is reduced or canceled, the good resilience of the silica gel will make the airbags rebound to the natural state and form negative pressure in the airbag cavities. Due to the pressure difference between the inside and the outside of each of the airbags, external gas will enter the airbag cavities inside the airbags to complete automatic inflation, so that an inflation device of a traditional air cushion can be omitted, the structure is simple, the production cost is low and the service life is long.

[0048] Typical embodiments embodying the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can have various changes in different embodiments without departing from the scope of the present disclosure, and the description and illustrations therein are essentially for illustration, not for limiting the present disclosure.

[0049] In addition, terms “first” and “second” are used merely for description, and cannot be construed as indicating or implying relative importance or implicitly indicating a quantity of indicated technical features. Therefore, features defined with “first” and “second” may explicitly or implicitly include one or more of the features. In the description of the present application, “a plurality of” means two or more, unless otherwise specifically defined.

[0050] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms “arrange”, “connected” and “connection” should be understood in a broad sense, for example, they may be fixed connection, may be detachable connection or integrated connection, may be mechanical connection, may also be electrical connection, may be direction connection, may also be indirect connection through an intermediate medium, and may be communication of two elements. Those of ordinary skill in the art may understand specific meanings of the above-mentioned terms in the present application based on the specific situation.

[0051] Referring to FIG. 1 to FIG. 6, the embodiments of the present disclosure provide a silica gel airbag air cushion 10. The silica gel airbag air cushion 10 can be used as a cushion for automobile seats, sofa and the like, and in addition, a plurality of silica gel airbag air cushions 10 can also be spliced into an air cushion bed for use.

[0052] Referring to FIG. 2 and FIG. 4, the silica gel airbag air cushion 10 includes a substrate 100 and a plurality of airbags 200 arranged on the substrate 100, where the plurality of airbags 200 are arranged at intervals; at least part of each of the airbags 200 protrudes from the substrate 100; a hollow airbag cavity 300 is formed in each of the airbags 200; and any two airbag cavities 300 do not communicate with each other.

[0053] The airbag cavities 300 do not communicate with one another, so that different airbags 200 are mutually independent. When a certain airbag 200 is damaged to cause leakage of the airbag cavity 300, the airbag cavities 300 in other airbags 200 will not be affected.

[0054] Referring to FIG. 3, in this embodiment, the plurality of airbags 200 arranged at intervals are in rows in a transverse direction and in columns in a vertical direction to form an array structure.

[0055] The silica gel airbag air cushion 10 is made of a silica gel material with good air permeability, the air permeability of the silica gel material is 10 times that of a rubber material, and the silica gel material also has excellent resilience and can rapidly rebound to the original state after being compressed.

[0056] It can be understood that compared with rubber and other materials with strong air tightness, the airbags 200 in the embodiments of the present application are made of a silica material with good air permeability. The airbags 200 will leak slowly after being compressed, and the airbags 200 will deform slowly. After the pressure is reduced or canceled, the good resilience of the silica gel will make the airbags 200 rebound to the natural state and form negative pressure in the airbag cavities 300. Due to the pressure difference between the inside and the outside of each of the airbags 200, external gas will enter the airbag cavities 300 inside the airbags 200 to complete automatic inflation, so that an inflation device of a traditional air cushion can be omitted, the structure is simple, the production cost is low and the service life is long.

[0057] In some possible embodiments, when a user sits or lies on the air cushion, the airbags 200 are deformed too fast, so that the user does not feel supported, and the use experience is poor.

[0058] Referring to FIG. 2 and FIG. 6, in view of this, in the silica gel airbag air cushion 10 in this embodiment, the height dimension of the airbag cavities 300 is greater than the radial dimension of the airbag cavities, so the airbag cavities 300 become steeper, and the airbag cavities 300 are not prone to deformation, which can bring lasting support experience to users.

[0059] Specifically, referring to FIG. 6, the height direction refers to a direction perpendicular to the substrate 100, the radial direction refers to a direction parallel to the substrate 100, the height dimension of the airbag cavities 300 is L1, the radial dimension of the airbag cavities 300 is L2, L1>L2, and under the condition that the orthographic projection area of the airbag cavities 300 on the substrate 100 is unchanged, the ratio of L1 to L2 is increased, and the airbag cavities 300 are not prone to deformation.

[0060] In this embodiment, the thickness of a bag wall of each of the airbags 200 is set to 0.4 mm to 1.5 mm; if the thickness of the bag wall is less than 0.4 mm, gas in the airbags 200 will escape too fast when the human body exerts pressure on the airbags 200, which can only provide a short-term support effect, resulting in poor use experience; and if the thickness of the bag wall is greater than 1.5 mm, it takes too long for the gas to re-enter the airbags 200 after the human body leaves the silica gel airbag air cushion 10, so that the effect of rapid self-inflation cannot be achieved. Of course, in other embodiments, the manufacturer can set the thickness of the bag wall of the airbags 200 to other values at the expense of some performance.

[0061] In this embodiment, the hardness of the silica gel airbag air cushion 10 is Shore hardness 50 degrees to 70 degrees; when the hardness of the silica gel is less than 50 degrees, the resilience of the silica gel is insufficient and the silica gel is easy to be crushed, which cannot provide a long-term support effect, resulting in poor use experience; and when the hardness of the silica gel is greater than 70 degrees, the silica gel is too hard, the effect of sitting on the air cushion is similar to that of sitting on a hard object, so the air cushion loses the elastic support effect.

[0062] Continuously referring to FIG. 6, specifically, each of the airbags 200 includes a first top part 210, a middle part 220 and a second top part 230 which are sequentially connected, where the middle part 220 is connected to the substrate 100, the first top part 210 and the second top part 230 are respectively connected to two opposite sides of the middle part 220, and the first top part 210 and the second top part 230 respectively protrude from two opposite sides of the substrate 100; and each of the airbag cavities 300 includes a first cavity 310 corresponding to the first top part 210, a middle cavity corresponding to the middle part 220 and a second cavity 330 corresponding to the second top part 230.

[0063] It can be understood that in other embodiments, one of the first top part 210 and the second top part 230 can be omitted, that is, the airbags 200 only protrude from a side of the substrate 100.

[0064] In this embodiment, the middle part 220 is cylindrical, the first top part 210 and the second top part 230 are semi-spherical, and bag walls of the first top part 210 and the second top part 230 are tangent to a bag wall of the middle part 220.

[0065] In this way, the connection between the airbags 200 and the substrate 100 is smoother, and the connection part is not prone to crack or breakage due to pressure deformation. In addition, the first top part 210 and the second top part 230 are set to be semi-spherical, the bearing area for the human body is larger, and a user can sit on the air cushion more comfortably. Of course, in other embodiments, the manufacturer can adjust the first top part 210, the second top part 230 and the middle part 220 into other shapes, such as a cuboid shape.

[0066] Continuously referring to FIG. 6, specifically, the middle part 220 includes a protruding part 221 protruding from the substrate 100, the protruding part 221 is connected to the first top part 210 or the second top part 230, and an extending direction of the protruding part 221 is perpendicular to an extending direction of the substrate 100.

[0067] Since the extending direction of the protruding part 221 is perpendicular to the extending direction of the substrate 100, the protruding part 221 is not easy to bend relative to the substrate 100, so that the protruding part 221 is not easy to deflate when stressed. The first top part 210 or the second top part 230 still can play a certain support role for the human body after being deflated, so that the silica gel airbag air cushion 10 can continuously provide support for the human body.

[0068] Referring to FIG. 2 and FIG. 6, in this embodiment, the first top part 210 and the second top part 230 are provided with protruding point structures 400, and the protruding point structures 400 protrude from outer surfaces of the first top part or the second top parts to achieve the massage effect. It can be understood that in other embodiments, one of the first top part 210 and the second top part 230 can be provided with the protruding point structure 400, and the manufacturer can freely adjust the setting position of the protruding point structure 400.

[0069] In this embodiment, the protruding point structure 400 and the first top part or the second top part are integrally formed, so that the protruding structure 400 can be connected to the first top part or the second top part more closely, and the problem that the protruding point structure 400 is separated from the first top part or the second top part after long-term use can be avoided.

[0070] Specifically, FIG. 2 shows that the protruding point structure 400 includes a central protruding point 410 and a plurality of edge protruding points 420 arranged around the central protruding point 410, and the central protruding point 410 is located at a largest end or a smallest end of the first top part or the second top part in a height direction. In this way, the combination of the central protruding point 410 and the edge protruding points 420 can provide a massage effect with larger coverage for the human body.

[0071] The edge protruding points 420 are arranged between the central protruding point 410 and the substrate 100, that is, the edge protruding points 420 are arranged closer to the substrate 100. When the top is crushed by the human body, the massage effect of the central protruding point 410 on the human body is weakened, and at this time, the edge protruding points 420 are in contact with the human body to provide the massage effect, so that the protruding point structure 400 can continuously provide the massage effect.

[0072] It should be noted that in this embodiment, the volume of the central protruding point 410 is greater than the volume of the edge protruding points 420, and by increasing the volume of the central protruding point 410, the central protruding point 410 still can provide a certain massage effect to the human body after the first top part or the second top part is partially crushed.

[0073] Referring to FIG. 2 and FIG. 3, specifically, the silica gel airbag air cushion 10 further includes a protruding edge 500, where the protruding edge 500 is arranged at an edge of the substrate 100 and extends continuously in a circumferential direction of the substrate 100, and at least part of the protruding edge 500 protrudes from the substrate 100. In this way, the protruding edge 500 can enhance the edge strength of the substrate 100 and prevent the edge of the substrate 100 from being torn.

[0074] Specifically, the silica gel airbag air cushion 10 is further provided with a hand-held hole 600. A user can insert a finger into the hand-held hole 600 to lift the silica gel airbag air cushion 10 and transfer the silica gel airbag air cushion 10. In addition, the hand-held hole 600 also can be used as a hanging hole for hanging a hook and the like. When a plurality of silica gel airbag air cushions 10 are spliced into an air cushion bed, the two adjacent silica gel airbag air cushions 10 can be fixed by inserting a nylon rope into the hand-held hole 600.

[0075] Specifically, the silica gel airbag air cushion 10 is further provided with a breathable hole 700. When the human body is pressed on the silica gel airbag air cushion 10, a side in contact with a bearing surface will form an approximately closed lower space with the bearing surface, the gas in the lower space can escape from the breathable hole 700, and the escaped gasflow can form a gas flow effect, so that the human body sitting on the silica gel airbag air cushion 10 can feel cool.

[0076] Although the present disclosure has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary rather than limiting. Since the present disclosure can be specifically implemented in various forms without departing from the spirit or essence of the present disclosure, it should be understood that the above-mentioned embodiments are not limited to any of the foregoing details, but should be broadly interpreted within the spirit and scope defined by the appended claims, so all changes and modifications that fall within the scope of the claims or their equivalents should be covered by the appended claims.
