[0056] According to an aerogel material body 130 heat insulation board structure 100 of the present invention, Figure 1 As shown, including:

[0057] A first membrane body 110 having a first membrane cavity 112 with a first open end 111;

[0058] The second membrane body 120 has a second membrane cavity 122 with a second open end 121, and the second open end 121 cooperates with the first open end 111 so that the first membrane cavity 112 and the second membrane cavity 122 jointly define a containing cavity A;

[0059] The aerogel material body 130 is filled in the accommodating cavity A; for example, the filler is aerogel fabric or aerogel paste.

[0060] That is to say, the first membrane cavity 112 and the second membrane cavity 122 jointly define a accommodating cavity A for filling the aerogel material body 130, so that the insulation board structure 100 can achieve insulation effect on the building by relying on the insulation effect of the aerogel material body 130 during use. In addition, the structure is simple, easy to produce and manufacture, low cost, good practicality, and easy to popularize.

[0061] Preferably, the first film body 110 and the second film body 120 are both building insulation plastic parts, for example, the first film body 110 and the second film body 120 are synthetic resins;

[0062] By designing the first film body 110 and the second film body 120 as building thermal insulation plastic parts, the thermal insulation effect of the thermal insulation board structure 100 can be further improved.

[0063] In one example of the present invention, Figure 4 and Figure 5 As shown, the first open end 111 forms a first thermal cover 113, and the second open end 121 forms a second thermal cover 123, and the first thermal cover 113 and the second thermal cover 123 are fixedly connected by a heat sealing process;

[0064] Generally, the heat sealing process is to heat the first heat sealing surface 113 and the second heat sealing surface 123 by a heat sealing device, and then press the first film body 110 and the second film body 120 together, so that the first film body 110 and the second film body 120 are fixedly connected together. The heat sealing process can make the sealing of the first film body 110 and the second film body 120 firm and have good sealing performance, which is suitable for the sealing of various plastic films and plastic bags and is relatively more efficient.

[0065] In one example of the present invention, Figure 1 As shown, it also includes: a first plate body 140 and a second plate body 150, the first plate body 140 is located in the first membrane cavity 112, and is arranged between the aerogel material body 130 and the bottom surface of the first membrane cavity 112, and the second plate body 150 is located in the second membrane cavity 122, and is arranged between the aerogel material body 130 and the bottom surface of the second membrane cavity 122;

[0066] By arranging the first plate body 140 and the second plate body 150 on both sides of the aerogel material body 130 , the aerogel material body 130 can be protected, thereby improving the overall structural strength of the thermal insulation board structure 100 .

[0067] Preferably, the first plate body 140 and the second plate body 150 are both made of synthetic resin.

[0068] In one example of the present invention, Figure 2 and Figure 3As shown, a plurality of first sound absorbing cavities 141 are formed on one side of the first plate body 140 close to the bottom surface of the first membrane cavity 112, and a plurality of second sound absorbing cavities 151 are formed on one side of the second plate body 150 close to the bottom surface of the second membrane cavity 122;

[0069] By setting a plurality of first sound absorbing cavities 141 on the first plate body 140, the noise on one side outside the heat insulation board can be absorbed. By setting a plurality of second sound absorbing cavities 151 on the second plate body 150, the noise on the other side outside the heat insulation board can be absorbed, thereby improving the overall internal and external sound insulation effect of the heat insulation board structure 100.

[0070] In an example of the present invention, the structures of the first sound absorbing cavity 141 and the second sound absorbing cavity 151 are that the inner diameter of the cavity gradually decreases from the inlet end to the direction away from the inlet end;

[0071] Taking the first sound absorbing cavity 141 as an example, according to the Huygens principle, when the noise sound wave is incident on the surface of the first plate body 140, a part of it is reflected on the surface of the first plate body 140, and the other part is transmitted to the inside of the first sound absorbing cavity 141, causing the air inside the first sound absorbing cavity 141 to vibrate and rub against the wall surface of the first sound absorbing cavity 141. Due to the viscosity and heat conduction effects, the sound energy can be converted into heat energy and consumed, and the noise sound wave can be repeatedly refracted on the wall surface of the first sound absorbing cavity 141, so that the sound energy is continuously converted and consumed, and the effect of sound absorption and noise reduction can be achieved repeatedly.

[0072] Take the first sound absorbing cavity 141 as an example for explanation, that is, the radial dimension of the end of the first sound absorbing cavity 141 close to the open end is greater than the radial dimension of the end of the first sound absorbing cavity 141 away from the open end. Similarly, the noise sound waves can be better refracted repeatedly on the wall surface of the first sound absorbing cavity 141, so that the sound energy is continuously converted and consumed, and the first sound absorbing cavity 141 can be used to better absorb the sound energy, and the sound absorption and noise reduction effect is better. Similarly, the second sound absorbing cavity 151 is similar to it, and it will not be repeated here.

[0073] In one example of the present invention, Figure 4 and Figure 5 As shown,

[0074] The plurality of first sound absorbing cavities 141 are arranged in an array along the transverse direction X and the longitudinal direction Y of the first plate body 140;

[0075] The plurality of second sound absorbing chambers 151 are arranged in an array along the transverse direction X and the longitudinal direction Y of the second plate body 150;

[0076] The transverse direction X and the longitudinal direction Y are perpendicular to each other.

[0077] Arranging a plurality of first sound absorbing cavities 141 and second sound absorbing cavities 151 in an array can enable the first plate body 140 and the second plate body 150 to better absorb external noise, thereby greatly improving the noise absorbing effect of the first sound absorbing cavity 141 and the second sound absorbing cavity 151 .

[0078] In one example of the present invention, Figure 4 and Figure 5 As shown,

[0079] A plurality of first sound guide holes 114 communicating with the first membrane cavity 112 are formed on the bottom surface of the first membrane cavity 112;

[0080] A plurality of second sound guide holes 124 communicating with the second membrane cavity 122 are formed on the bottom surface of the second membrane cavity 122;

[0081] By opening the first sound guide hole 114 on the bottom surface of the first membrane cavity 112, external noise located on the side of the first membrane cavity 112 can be introduced into the first membrane cavity 112 through the first sound guide hole 114, so that the noise is absorbed by the first sound absorption cavity 141 of the first plate body 140;

[0082] By opening a second sound guide hole 124 on the bottom surface of the second membrane cavity 122 , external noise located on the side of the second membrane cavity 122 can be introduced into the second membrane cavity 122 through the second sound guide hole 124 , so that the noise is absorbed by the second sound absorbing cavity 151 of the second plate body 150 .

[0083] In one example of the present invention, Figure 1 As shown,

[0084] The projection of the first sound guide hole 114 in the depth direction Z of the first membrane cavity 112 of the first plate body 140 has an overlapping area with the first sound absorbing cavity 141;

[0085] The projection of the second sound guide hole 124 in the depth direction Z of the second membrane cavity 122 of the second plate body 150 has an overlapping area with the second sound absorbing cavity 151;

[0086] The depth direction Z, the transverse direction X and the longitudinal direction Y are perpendicular to each other.

[0087] In short, the first sound guide hole 114 and the first sound absorbing cavity 141 have at least a partial overlap in the depth direction Z, so that the external noise located on the side of the first membrane cavity 112 can be transmitted to the first sound absorbing cavity 141 at the shortest distance and then absorbed; the second sound guide hole 124 and the second sound absorbing cavity 151 have at least a partial overlap in the depth direction Z, so that the external noise located on the side of the second membrane cavity 122 can be transmitted to the second sound absorbing cavity 151 at the shortest distance and then absorbed;

[0088] Preferably, the first sound guide hole 114 is disposed opposite to the first sound absorbing cavity 141 , and the second sound guide hole 124 is disposed opposite to the second sound absorbing cavity 151 .

[0089] In one example of the present invention, the aerogel material body 130 is connected to the first plate body 140 and the second plate body 150 by an adhesive. The adhesive can be used to form an integral structure of the first plate body 140, the second plate body 150 and the aerogel material body 130, which helps to install the insulation board structure 100 on the one hand, and also helps to improve the structural strength of the insulation board on the other hand.

[0090] In one example of the present invention, the thickness dimension of the aerogel material body 130 in the depth direction Z is greater than half of the dimension of the accommodating cavity A in the depth direction Z;

[0091] That is to say, the thickness of the aerogel material body 130 should be greater than half of the depth of the accommodating cavity A, so as to ensure that there is a sufficient thickness of the aerogel material body 130 in the accommodating cavity A, thereby improving the heat insulation effect of the aerogel material body 130.

[0092] The exemplary implementation of the aerogel material body 130 insulation board structure 100 proposed in the present invention is described in detail above with reference to the preferred embodiments. However, those skilled in the art will appreciate that, without departing from the concept of the present invention, various modifications and variations may be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention may be combined in various ways without exceeding the protection scope of the present invention, which is determined by the appended claims.
