Abstract
The utility model discloses a sound absorption automobile inner decorating plate. The sound absorption automobile inner decorating plate overcomes the shortage that the existing automobile inner decorating plate does not possess a sound absorption function. The sound absorption automobile inner decorating plate comprises a body. The body is provided with an elastic connecting layer. The connecting layer is provided with a first polyester fiber layer and a second polyester fiber layer. The connecting layer attaches to the first polyester fiber layer. An interlayer is arranged between the first polyester fiber layer and the second polyester fiber layer. A plurality of sound absorption holes are formed in the interlayer. The sound absorption automobile inner decorating plate is also suitable in the situations where the existing automobile inner decorating plate is suitable and possesses the sound absorption holes which can match with the two polyester fiber layers to form a sound absorption cavity. The sound absorption automobile inner decorating plate has the advantages of absorbing sound and separating part of noise by utilizing the polyester fiber layers.
Description
Technical field
The utility model relates to a kind of vehicular spare parts, relates in particular to a kind of interior decoration panel for automobile.
Background technology
Interior decoration panel for automobile is the common structure in the car, and it can play and block vehicle body sheet metal, improves the effect of occupant's ride comfort.Automobile produces noise thereby tire can be passed to vehicle body by body mounting with vibrations, and finally cause producing the noise that causes because of vibrations on the interior decoration panel for automobile, and existing interior decoration panel for automobile is still not enough to some extent aspect the noise absorption function in motion.
China Patent Publication No. CN201842034U, open day on May 25th, 2011, the name of utility model is called low foaming decorative sheet for automobile, this application case discloses a kind of low foaming decorative sheet for automobile, it is characterized in that: the low foamed board upper surface of described PVC is fixed with one deck and decorates with PVC veneer film, and it is fixed that decoration presses solidly by environment friendly flame-retardant adhesives and the low foamed board composite cold of PVC with PVC veneer film.This utility model weak point is still the function with absorption of noise.
The utility model content
The utility model has overcome the deficiency that existing interior decoration panel for automobile does not have the noise absorption function, and a kind of interior decoration panel for automobile with noise absorption function is provided.
The utility model is achieved through the following technical solutions:
A kind of sound absorption interior decoration panel for automobile, comprise body, described body is provided with elastomeric articulamentum, described articulamentum is provided with the first layer of polyester fiber, the second layer of polyester fiber, described articulamentum and the first layer of polyester fiber are fitted, be provided with interlayer between described the first layer of polyester fiber and the second layer of polyester fiber, described interlayer is provided with some bloops.Layer of polyester fiber can play deadening, after noise is passed to body outside by car, elastomeric articulamentum is by the vibrations of self, can eliminate partial noise, then the first layer of polyester fiber has been isolated partial noise, simultaneously vibrations and noise transfer to interlayer, the interlayer both sides all are layer of polyester fiber, be provided with bloop in the interlayer, being equivalent to has a plurality of hollow cavitys between two layer of polyester fiber, these bloops can further be eliminated and noise isolation, so that the noise that the occupant hears reaches minimum.
As preferably, described articulamentum is the articulamentum of rubber, and described articulamentum thickness is not less than the sixth of the first poly-ester fibres layer thickness or the second poly-ester fibres layer thickness.The rubber articulamentum can be eliminated partial noise by the vibrations of itself, make simultaneously whole automotive trim panel larger vibrations can not occur, therefore its thickness can not be too small, need to accept or reject according to the thickness of layer of polyester fiber, comprehensive consideration is chosen the sixth that its thickness is not less than the first poly-ester fibres layer thickness or the second poly-ester fibres layer thickness.
As preferably, described interlayer is PE material interlayer, and described bloop is circular bloop, and described thickness of interlayer is not less than 1/10th of the first poly-ester fibres layer thickness.PE is polyethylene, its lighter weight, can additionally not increase too much weight, PE interlayer and the first layer of polyester fiber and the second layer of polyester fiber are interosculated, and the circular bloop on the interlayer has just become some columniform cavitys, therefore can play the effect of eliminating noise, and in order to guarantee erasure effect, cavity volume can not be too small, therefore thickness of interlayer had requirement, chooses thickness of interlayer at this and be not less than 1/10th of the first poly-ester fibres layer thickness.
Therefore, the beneficial effects of the utility model are: (1) has bloop, can cooperate two layer of polyester fiber to form the noise reduction cavity, plays the effect of eliminating noise; (2) have layer of polyester fiber, can the isolated part noise.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of the utility model interlayer.
Among the figure: body 1, articulamentum 2, the first layer of polyester fiber 3, the second layer of polyester fiber 4, interlayer 5, bloop 6.
The specific embodiment
Below by embodiment, by reference to the accompanying drawings the technical solution of the utility model is described further:
A kind of sound absorption interior decoration panel for automobile as shown in Figure 1 and Figure 2, comprise body 1, described body 1 is provided with elastomeric articulamentum 2, described articulamentum 2 is provided with the first layer of polyester fiber 3, the second layer of polyester fiber 4, described articulamentum 2 and the first layer of polyester fiber 3 are fitted, be provided with interlayer 5 between described the first layer of polyester fiber 3 and the second layer of polyester fiber 4, described interlayer 5 is provided with some bloops 6.Layer of polyester fiber can play deadening, can isolate part vibrations.Described articulamentum 2 is the articulamentum 2 of rubber, and described articulamentum 2 thickness are not less than the sixth of the first layer of polyester fiber 3 thickness or the second layer of polyester fiber 4 thickness.Rubber articulamentum 2 can be eliminated partial noise by the vibrations of itself, make simultaneously whole automotive trim panel larger vibrations can not occur, therefore its thickness can not be too small, need to accept or reject according to the thickness of layer of polyester fiber, comprehensive consideration is chosen the sixth that its thickness is not less than the first layer of polyester fiber 3 thickness or the second layer of polyester fiber 4 thickness.Described interlayer 5 is PE material interlayer 5, and described bloop 6 is circular bloop 6, and described interlayer 5 thickness are not less than 1/10th of the first layer of polyester fiber 3 thickness.PE is polyethylene, and its lighter weight can additionally not increase too much weight.And in order to guarantee erasure effect, cavity volume can not be too small, therefore interlayer 5 thickness had requirement, chooses interlayer 5 thickness at this and be not less than 1/10th of the first layer of polyester fiber 3 thickness.
After noise was passed to body 1 outside by car, elastomeric articulamentum 2 can be eliminated partial noise by the vibrations of self, and then the first layer of polyester fiber 3 has been isolated again partial noise, simultaneously vibrations and noise transfer to interlayer 5.PE interlayer 5 and the first layer of polyester fiber 3 and the second layer of polyester fiber 4 are interosculated, circular bloop 6 on the interlayer 5 has just become some columniform cavitys, it is air in the cavity, after sound wave is passed to cavity, its propagation slows down in solid relatively greatly, what therefore it can be decayed is more, thus can play the effect of further isolation and elimination noise, so that the noise that the occupant hears reaches minimum.
