Abstract

The utility model discloses a inhale sound shock attenuation bubble cotton, include: a damping rubber layer; the sound insulation layer is fixedly connected with the damping rubber layer; the sound absorption layer is fixedly connected to one side of the sound insulation layer, which is far away from the damping rubber layer; the sound insulation layer is fixedly connected to one side, far away from the sound insulation layer, of the sound absorption layer. The utility model discloses a set up the cushion rubber layer and the cotton layer of bubble can play absorbing effect, can play syllable-dividing effect through setting up the puigging, can play the effect of inhaling the sound through the sound absorbing layer, and then realize that this structure can play the good effect of inhaling the sound shock attenuation.

Description

Sound-absorbing shock-absorbing foam

Technical Field

The utility model belongs to the technical field of the bubble is cotton, especially, relate to a inhale sound shock attenuation bubble cotton.

Background

The foam is a material foamed by plastic particles, has a series of characteristics of elasticity, light weight, quick pressure-sensitive fixation, convenient use, free bending, ultrathin volume, reliable performance and the like, and is combined with other materials to meet different requirements at present in order to enable the foam to have different characteristics. In the existing foam structure, the sound absorption effect is generally poor.

Therefore, a sound-absorbing and shock-absorbing foam is provided to solve the problems.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides an inhale sound shock attenuation bubble cotton, the device can play good shock attenuation and syllable-dividing effect to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a sound-absorbing and shock-absorbing foam comprising:

a damping rubber layer;

the sound insulation layer is fixedly connected with the damping rubber layer;

the sound absorption layer is fixedly connected to one side, far away from the damping rubber layer, of the sound insulation layer;

the sound insulation layer is fixed on the sound absorption layer, and the foam layer is fixedly connected to one side, far away from the sound insulation layer, of the sound absorption layer.

Furthermore, the soundproof layers are provided with two groups and are respectively and fixedly connected to two sides of the damping rubber layer.

Further, the damping rubber layer is made of butyl rubber, the sound insulation layer is made of fiberboard, the sound absorption layer is made of polyurethane foam, and the foam layer is made of pearl wool.

Furthermore, the puigging is the fold structure, shock-absorbing rubber layer and sound absorbing layer are used for filling the setting with puigging both sides.

Further, the convex angle and the concave angle of the folds of the sound insulation layer are both smaller than 90 degrees.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a set up the yielding rubber layer and the cotton layer of bubble can play absorbing effect, can play syllable-dividing effect through setting up the puigging, can play the effect of inhaling the sound through the sound absorbing layer, and then realize that this structure can play good sound shock attenuation effect of inhaling.

Drawings

Fig. 1 is the utility model provides a inhale cotton overall structure schematic diagram of sound shock attenuation bubble.

In the figure: 1. a damping rubber layer; 2. a sound insulating layer; 3. a sound absorbing layer; 4. and (5) soaking a cotton layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Referring to fig. 1, the sound-absorbing and shock-absorbing foam comprises a shock-absorbing rubber layer 1, a sound-insulating layer 2, a sound-absorbing layer 3 and a foam layer 4.

And puigging 2 and cushion rubber layer 1 fixed connection, 3 fixed connection of sound absorbing layer are in the one side that cushion rubber layer 1 was kept away from to puigging 2, and foam layer 4 fixed connection is in the one side that sound absorbing layer 3 kept away from puigging 2, and this fixed mode is can be fixed by mode such as gluing.

Wherein cushion rubber layer 1 is the butyl rubber material, and puigging 2 is the fibreboard, and sound absorbing layer 3 is the polyurethane foam material, and bubble cotton layer 4 is the cotton material of pearl to the realization plays absorbing effect through the high damping nature that cushion rubber layer 1 and bubble cotton layer 4 have through its self material, and plays the effect that plays the reflection to the sound wave through puigging 2, plays the effect of inhaling the sound through sound absorbing layer 3.

And wherein can be provided with the one deck with puigging 2, it sets up in cushion rubber layer 1 one side, and if both sides all need play good sound absorbing effect, can be provided with two-layer with puigging 2, and fixed connection respectively is in cushion rubber layer 1 both sides to realize that both sides homoenergetic enough play good sound absorbing effect.

Puigging 2 is the fold structure, and damping rubber layer 1 and sound absorbing layer 3 are used for filling the setting with 2 both sides of puigging, and the bulge angle and the sunk angle of 2 folds of puigging all are less than 90 degrees to realize can the better position in 2 caves in puigging of sound wave repeated reflection, absorb with 3 absorptions of sound absorbing layer in order to realize better.

The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
