Abstract
The utility model discloses a kind of automobile using sound panel, including sound insulation fibrous layer, the lower surface of the sound insulation fibrous layer is fixedly connected with diatom mud layer, the lower surface of the diatom mud layer is fixedly connected with acoustical cotton layer, the lower surface of the acoustical cotton layer is fixedly connected with foam insulation, and the lower surface of the foam insulation is fixedly connected with layers of insulating fabric.The automobile using sound panel, pass through foam insulation, the low frequency segment that car engine is sent can be absorbed well, the high frequency segment that harmful car engine sends can be absorbed well by the diatom mud layer of setting, and low frequency segment is further decayed, influence of the high temperature to sound panel is reduced from largely injury of the reduction noise to human body, and by the layers of insulating fabric of design, lifts soundproof effect.
Description
Technical field
The utility model belongs to car engine technical field of sound isolation, and in particular to a kind of automobile using sound panel.
Background technology
During normally travel, the external temperature of car engine can be typically controlled at 80-90 DEG C or so, automobile engine cover every
In sound, often because temperature keeps high temperature the soundproof effect of sound panel is reduced, it is impossible to reach good soundproof effect, and
Because the high-frequency sound of car engine is very sharp, health can be seriously affected.
Utility model content
The purpose of this utility model is to provide a kind of automobile using sound panel, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of automobile using sound panel, including sound insulation are fine
Layer is tieed up, the lower surface of the sound insulation fibrous layer is fixedly connected with diatom mud layer, and the lower surface of the diatom mud layer, which is fixed, to be connected
Acoustical cotton layer is connected to, the lower surface of the acoustical cotton layer is fixedly connected with foam insulation, the bottom of the foam insulation
Surface is fixedly connected with layers of insulating fabric.
Preferably, the diatom mud layer is the diatom ooze flaggy that thickness is not less than 2mm.
Preferably, the foam insulation is polyurethane foam thermal baffle layer.
Preferably, the sound insulation fibrous layer is polyester soundproof fiberboard layer.
Preferably, the layers of insulating fabric is alumina silicate fibre thermal baffle layer.
Preferably, the acoustical cotton layer is high temperature resistant acoustical cotton layer.
Technique effect of the present utility model and advantage：The automobile using sound panel, by foam insulation, it can inhale well
The low frequency segment that car engine is sent is received, harmful car engine can be absorbed well by the diatom mud layer of setting
The high frequency segment sent, and low frequency segment is further decayed, from largely injury of the reduction noise to human body, and passing through
The layers of insulating fabric of design reduces influence of the high temperature to sound panel, lifts soundproof effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1 sound insulation fibrous layer, 2 diatom mud layers, 3 acoustical cotton layers, 4 foam insulations, 5 layers of insulating fabrics.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model provides a kind of automobile using sound panel as shown in Figure 1, including sound insulation fibrous layer 1, the sound insulation
The lower surface of fibrous layer 1 is fixedly connected with diatom mud layer 2, and the lower surface of the diatom mud layer 2 is fixedly connected with acoustical cotton
Layer 3, the lower surface of the acoustical cotton layer 3 is fixedly connected with foam insulation 4, and the lower surface of the foam insulation 4 is consolidated
Surely it is connected with layers of insulating fabric 5.
Specifically, the diatom mud layer 2 is the diatom ooze flaggy that thickness is not less than 2mm.
Specifically, the foam insulation 4 is polyurethane foam thermal baffle layer.
Specifically, the sound insulation fibrous layer 1 is polyester soundproof fiberboard layer.
Specifically, the layers of insulating fabric 5 is alumina silicate fibre thermal baffle layer.
Specifically, the acoustical cotton layer 3 is high temperature resistant acoustical cotton layer.
Specifically, the automobile using sound panel, by foam insulation 4, can absorb well car engine send it is low
Frequency segment, the high frequency segment that harmful car engine sends can be absorbed well by the diatom mud layer 2 of setting, and
Low frequency segment is further decayed, from largely injury of the reduction noise to human body, and the layers of insulating fabric 5 for passing through design
Influence of the high temperature to sound panel is reduced, lifts soundproof effect.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Progress equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc.,
It should be included within the scope of protection of the utility model.
