[0031] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.
[0032] In addition, the terms "first", "second", etc. are used only for descriptive purposes and should not be construed as implying or suggesting relative importance or an indicated number of the technical features indicated. Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified and limited.
[0033] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0034] Reference Figures 1 to 6 The utility model embodiment provides a silica gel air bag air cushion 10, silica gel air bag air cushion 10 can be used as the cushion of car seat, sofa etc., in addition, a plurality of silica gel air bag air cushion 10 can be spliced into air cushion bed and used.
[0035] Combined with reference Figure 2 And Figure 4 The silica gel air bag air cushion 10 includes a substrate 100 and a plurality of air bags 200 disposed on the substrate 100. The plurality of air bags 200 are spaced apart, and at least a portion of each air bag 200 protrudes from the substrate 100. Each air bag 200 has a hollow air bag cavity 300 disposed therein, and any two air bag cavities 300 are not connected.
[0036] The non-communication between the air bag cavities 300 makes the different air bags 200 independent of each other. When a certain air bag 200 is damaged and the air bag cavity 300 leaks, the air bag cavities 300 in other air bags 200 will not be affected.
[0037] Reference Figure 3 In the present embodiment, the plurality of spaced apart air bags 200 are arranged in rows in the transverse direction and in columns in the vertical direction to form an array structure.
[0038] The silica gel air bag air cushion 10 uses silica gel material with good air permeability. The air permeability of the silica gel material is more than 10 times that of rubber material. The silica gel material also has excellent resilience and can quickly recover to its original state after being compressed.
[0039] It can be understood that, compared with materials such as rubber with strong air tightness, the air bag 200 in the embodiment of the application is composed of silica gel material with good air permeability. The air bag 200 will slowly leak air after being pressed and slowly deform. When the pressure becomes smaller or the pressure is removed, the good resilience of the silica gel will make the air bag 200 rebound to the natural state and form a negative pressure in the air bag cavity 300. Due to the pressure difference between the inside and outside of the air bag 200, the external gas will enter the air bag cavity 300 inside the air bag 200, completing automatic inflation. Therefore, the inflation device of the traditional air cushion can be omitted, the structure is simple, the production cost is low, and the service life is long.
[0040] In some possible embodiments, when the user sits or lies on the air cushion, the air bag 200 deforms too fast under force, resulting in that the user does not feel supported and the use experience is poor.
[0041] In combination with reference Figure 2 and Figure 6 To this end, in the silica gel air bag air cushion 10 of the embodiment, the height dimension of the air bag cavity 300 is greater than the radial dimension thereof, the air bag cavity 300 becomes steeper, the air bag cavity 300 is not easy to deform, and the user can have a lasting support experience.
[0042] Specifically, referring to Figure 6 , the height direction refers to the direction perpendicular to the substrate 100, the radial direction refers to the direction parallel to the substrate 100, the height dimension of the air bag cavity 300 is L1, the radial dimension of the air bag cavity 300 is L2, L1>L2, under the condition that the area of the air bag cavity 300 in the orthographic projection on the substrate 100 is unchanged, the ratio of L1 to L2 increases, and the air bag cavity 300 is not easy to deform.
[0043] In the embodiment, the wall of the air bag 200 is set to 0.4 mm to 1.5 mm. If the thickness of the wall is less than 0.4 mm, the gas in the air bag 200 escapes too fast when the human body applies pressure to the air bag 200, and only a short-term support effect can be provided, and the use experience is poor. If the thickness of the wall is greater than 1.5 mm, after the human body leaves the silica gel air bag air cushion 10, it takes too long for the gas to re-enter the inside of the air bag 200, and the effect of rapid self-inflation cannot be achieved. Of course, in other embodiments, the manufacturer can set the wall of the air bag 200 to other values while sacrificing part of the use performance.
[0044] In the embodiment, the hardness of the silica gel air bag 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 easily crushed, and a long-term support effect cannot be provided, and the use experience is poor. When the hardness of the silica gel is greater than 70 degrees, the silica gel is too hard, and sitting on the air cushion is similar to sitting on a hard object, and the air cushion loses the effect of elastic support.
[0045] Continuing to refer toFigure 6 Specifically, the air bag 200 comprises a first top portion 210, an intermediate portion 220 and a second top portion 230 connected in sequence, the intermediate portion 220 is connected with the base plate 100, the first top portion 210 and the second top portion 230 are respectively connected to opposite sides of the intermediate portion 220, and the first top portion 210 and the second top portion 230 respectively protrude from opposite sides of the base plate 100, the air bag cavity 300 comprises a first cavity 310 corresponding to the first top portion 210, an intermediate cavity corresponding to the intermediate portion 220 and a second cavity 330 corresponding to the second top portion 230.
[0046] It can be understood that in other embodiments, one of the first top portion 210 and the second top portion 230 can be omitted, that is, the air bag 200 only protrudes from one side of the base plate 100.
[0047] In the embodiment, the intermediate portion 220 is cylindrical, the first top portion 210 and the second top portion 230 are both hemispherical, and the bag walls of the first top portion 210 and the second top portion 230 are tangent to the intermediate portion 220.
[0048] In this way, the connection between the air bag 200 and the base plate 100 is smoother, and the connection part is not easy to crack or break due to pressure deformation; in addition, the first top portion 210 and the second top portion 230 are set to be hemispherical, the bearing area on the human body is larger, and the user is more comfortable when sitting on the air cushion. Of course, in other embodiments, manufacturers can adjust the first top portion 210, the second top portion 230 and the intermediate portion 220 to other shapes, such as a cuboid.
[0049] Continuing to refer to Figure 6 Specifically, the intermediate portion 220 comprises a protruding portion 221 protruding from the base plate 100, the protruding portion 221 is connected with the first top portion 210 or the second top portion 230, and the extension direction of the protruding portion 221 is perpendicular to the extension direction of the base plate 100.
[0050] Since the extension direction of the protruding portion 221 is perpendicular to the extension direction of the base plate 100, the protruding portion 221 is not easy to bend relative to the base plate 100, so that the protruding portion 221 is not easy to be crushed when stressed, and can still support the human body after the first top portion 210 or the second top portion 230 is crushed, so that the silica gel air bag air cushion 10 can continuously provide support to the human body.
[0051] In combination with reference to Figure 2 and Figure 6 In the embodiment, the first top portion 210 and the second top portion 230 are both provided with a bump structure 400, the bump structure 400 protrudes from the outer surface of the top portion to achieve the effect of massage. It can be understood that in other embodiments, the bump structure 400 can be provided only on one of the first top portion 210 and the second top portion 230, and manufacturers can freely adjust the setting position of the bump structure 400.
[0052] In the embodiment, the convex structure 400 is integrally formed with the top, so that the connection between the convex structure 400 and the top is more compact, and the problem that the convex structure 400 is separated from the top after long-term use does not occur.
[0053] Specifically, Figure 2 It is shown that the convex structure 400 includes a central convex point 410 and a plurality of edge convex points 420 arranged around the central convex point 410, and the central convex point 410 is located at the maximum end or the minimum end in the height direction of the top. In this way, the combination of the central convex point 410 and the edge convex point 420 can provide a larger massage effect to the human body.
[0054] The edge convex point 420 is arranged between the central convex point 410 and the substrate 100, that is, the edge convex point 420 is arranged closer to the substrate 100. When the top is pressed by the human body, the massage effect of the central convex point 410 on the human body is weakened, at this time, the edge convex point 420 contacts the human body to provide a massage effect, so that the convex structure 400 can continuously provide a massage effect.
[0055] It should be noted that in the embodiment, the volume of the central convex point 410 is greater than the volume of the edge convex point 420. By increasing the volume of the central convex point 410, the central convex point 410 can still provide a certain massage effect to the human body after the top is pressed.
[0056] For reference Figure 2 and Figure 3 Specifically, the silica gel air bag cushion 10 further includes a convex edge 500, which is arranged at the edge of the substrate 100 and extends continuously along the circumference of the substrate 100, and at least part of the convex edge 500 protrudes from the substrate 100. In this way, the convex edge 500 can play a role in strengthening the edge strength of the substrate 100, preventing the edge of the substrate 100 from being torn.
[0057] Specifically, the silica gel air bag cushion 10 is further provided with a hand hole 600, and the user can insert fingers into the hand hole 600 to lift the silica gel air bag cushion 10 and move the silica gel air bag cushion 10. In addition, the hand hole 600 can also be used as a hanging hole for hanging on a hook or the like. When a plurality of silica gel air bag cushions 10 are spliced into a cushion bed, nylon ropes or the like can be used to pass through the hand hole 600 to fix two adjacent silica gel air bag cushions 10.
[0058] Specifically, the silica gel air bag cushion 10 is further provided with a breathable hole 700. When the human body is pressed on the silica gel air bag cushion 10, the side in contact with the bearing surface will form an approximately airtight lower space with the bearing surface. The gas in the lower space can escape through the breathable hole 700, and the escaping gas flow can form a gas flow effect, making the human body acting on the silica gel air bag cushion 10 feel cool.
[0059] While the present application has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. As mentioned above, changes and modifications can be made to the above-described embodiments without departing from the spirit or scope of the application. Therefore, the above-described embodiments are to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
