Abstract
The utility model relates to the technical field of auto parts, in particular to an automobile instrument panel structure with a sound-proof effect. The automobile instrument panel structure comprises an instrument panel main body, wherein the instrument panel main body comprises an inner surface for mounting an instrument and an outer surface facing to one side of an automobile engine; the outer surface is provided with sound absorption cups of which the bottoms are connected with the outer surface; an opening is formed in the top of each sound absorption cup; sound-proof cotton is arranged in the cavity of each sound absorption cup. According to the utility model, part of noise can be reflected back by the outer side surfaces of the sound absorption cups, and part of noise enters the cavities of the sound absorption cups and is repeatedly reflected and absorbed by the sound-proof cotton in the cavities, so that noise is effectively processed, noise penetrating the instrument panel to enter a cab is greatly reduced, and accordingly, a favorable sound-proof effect is achieved.
Description
Technical field
The utility model relates to vehicular spare parts technical field, relates in particular to a kind of automobile instrument panel structure with soundproof effect.
Background technology
In the driving procedure of automobile, driving engine is the largest source of noise, if excessive noise enters operator's compartment, can cause serious impact to the experience of driving of navigating mate.Automobile instrument panel is between driving engine and chaufeur, and motor noise easily directly enters operator's compartment through automobile instrument panel, give chaufeur drive impact, be therefore necessary automobile instrument panel to carry out sound Insulation Design.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile instrument panel structure with soundproof effect for the deficiencies in the prior art.
To achieve these goals, the utility model is by the following technical solutions:
A kind of automobile instrument panel structure with soundproof effect, comprise gauge panel body, described gauge panel body comprises for the inside face of instrument being installed and towards the outside face of automotive engine one side, described outside face is provided with sound-absorbing cup, the bottom of described sound-absorbing cup is connected with outside face, the top of sound-absorbing cup is provided with opening, in the cavity of sound-absorbing cup, is provided with acoustical cotton.
Wherein, the cross-sectional plane of described sound-absorbing cup is trapezoidal.
Preferably, described trapezoidal upper base is 1/4～3/4 with the length ratio of going to the bottom.
Further preferred, described trapezoidal upper base is 1/2 with the length ratio of going to the bottom.
Wherein, the sound-absorbing cup of described sound-absorbing cup for being made by hard plastic sheet.
Further, described sound-absorbing cup comprises a plurality of, and a plurality of sound-absorbing cups are disposed in an evenly spaced relation in the outside face of gauge panel body.
The beneficial effects of the utility model are: the automobile instrument panel structure with soundproof effect of the present utility model, outside face at gauge panel body is provided with sound-absorbing cup, the bottom of described sound-absorbing cup is connected with outside face, the top of sound-absorbing cup is provided with opening, in the cavity of sound-absorbing cup, be provided with acoustical cotton, in the process of using, the lateral surface of sound-absorbing cup can reflect back part noise, part noise enters the cavity interior process multiple reflections of sound-absorbing cup and is absorbed by the acoustical cotton in cavity, noise is carried out to actv. processing, greatly reduce the noise that enters operator's compartment through gauge panel, there is good soundproof effect.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section with the gauge panel structure of soundproof effect of the present utility model.
Reference numeral comprises:
1-gauge panel body; 11-inside face; 12-outside face; 2-sound-absorbing cup; 3-acoustical cotton.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of automobile instrument panel structure with soundproof effect, comprise gauge panel body 1, described gauge panel body 1 comprises for the inside face 11 of instrument being installed and towards the outside face 12 of automotive engine one side, described outside face 12 is provided with sound-absorbing cup 2, the bottom of described sound-absorbing cup 2 is connected with outside face 12, the top of sound-absorbing cup 2 is provided with opening, in the cavity of sound-absorbing cup 2, be provided with acoustical cotton 3, in the process of using, the lateral surface of sound-absorbing cup 2 can reflect back part noise, part noise enters the cavity interior process multiple reflections of sound-absorbing cup 2 and is absorbed by the acoustical cotton 3 in cavity, noise is carried out to actv. processing, greatly reduce the noise that enters operator's compartment through gauge panel, there is good soundproof effect.
Wherein, the cross-sectional plane of described sound-absorbing cup 2 is trapezoidal, concrete, described sound-absorbing cup 2 is pyramid, the top of the pyramid sound-absorbing cup 2 formation opening of pruning, can increase the face area of the lateral surface of sound-absorbing cup 2, thereby increases the reflective area of noise, the reflection efficiency that improves noise, has guaranteed the utlity model has good sound insulation and noise reduction effect.
Preferably, described trapezoidal upper base is 1/4～3/4 with the length ratio of going to the bottom, further preferred, described trapezoidal upper base is 1/2 with the length ratio of going to the bottom, with this understanding, the lateral wall of described trapezoidal sound-absorbing cup 2 can reflect back part noise, and the inner chamber of sound-absorbing cup 2 forms resonant cavity, the noise that enters this resonant cavity inside absorbs through multiple reflections and by the acoustical cotton 3 in cavity, sound insulation and noise reduction successful.
Wherein, the sound-absorbing cup 2 of described sound-absorbing cup 2 for being made by hard plastic sheet, concrete, described hard plastic sheet can be selected hard PVC sheet, and not only noise reflecting effect is good, and cost is low.
Wherein, described sound-absorbing cup 2 comprises a plurality of, and a plurality of sound-absorbing cups 2 are disposed in an evenly spaced relation in the outside face 12 of gauge panel body 1, further improve noise reflection efficiency, improves the design's sound insulation and noise reduction effect.
Above embodiment is the restriction for the technical solution of the utility model is described but not to the utility model protection domain only; although the utility model is explained in detail with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
