Abstract
The invention provides a soundproof panel for an automobile. The soundproof panel comprises a first panel, a second panel, and soundproof cotton arranged between the first panel and the second panel, wherein keels are arranged on the first panel; the keels and the first panel are formed by one-time injection; the keels form a grid-shaped structure in a criss-cross manner; each grid shape forms a soundproof unit with a hollow structure; the soundproof cotton is filled in the soundproof units. The soundproof panel further comprises a connection device used for connecting the first panel with the second panel. The soundproof panel provided by the invention has the following beneficial effects that: the interior noise of the automobile can be effectively lowered while the weight and the cost of the automobile are not obviously increased, with no changes on the original panel structure of the automobile, and the purpose can be realized only by adding one working procedure; the soundproof panel is low in machining cost, simple in structure, easy to detach, convenient to repair, capable of updating a soundproof effect by replacing an interior soundproof layer material, free from generating hazardous substances by using the soundproof material, and environment-friendly and safe.
Description
Technical field
The invention belongs to vehicular spare parts field, especially relate to a kind of auto sound panel.
Background technology
Noise is many-sided on the impact of health, and function of noise, in people's central nerves system, makes the corticocerebral excitement of people and suppresses dysequilibrium, causes conditioned reflex abnormal, and cerebrovascular tension force is damaged.Noise also has serious harmful effect to digestive system, cardiovascular system, can cause indigestion, poor appetite, n and V, thereby cause the attack rate of stomach trouble and gastric ulcer to improve, make the attack rate of hypertension, artery sclerosis and coronary heart disease than the obvious raising of normal circumstances.Noise also can cause harmful effect to the organs of vision.
On the other hand, car noise not only increases chaufeur and occupant's fatigue, and affects the driving safety of automobile.As the important critical for the evaluation of vehicle ride comfort, car noise also can reflect design level and the technological level of manufacturer to a great extent.Therefore, controlling car noise is also the direction that automobile designers is pursued to minimum level.
Car noise has four " sources ": the noise that engine noise, tire noise, airborne noise and body structure cause.The means that reduce noise are a lot, tire noise and noise of air that damping block and sound-absorbing pad can fine reduction vehicle traveling processes.Automobile generally can adopt the panel of hollow and trim panel etc. in order to lower weight and reducing costs, the soundproof effect of this panel or trim panel is poor, effectively lattice keep off noise, therefore, when increasing sound isolating layer on existing car panel and trim panel, the weight of unconspicuous increase automobile and cost become the important research direction that reduces car noise.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of auto sound panel, when being especially applicable to not obvious increase vehicle weight and cost, provides the scheme of effective reduction automotive interior noise.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of auto sound panel, comprise the first panel, the second panel and be arranged on the first panel and the second panel between Sound-proof material, on described the first panel, be provided with keel, wherein, described keel and the first panel are single injection-molded, described keel form grating texture crisscrossly, each trellis forms a sound insulation unit with hollow structure, described Sound-proof material is filled in described sound insulation unit, also comprises described the first panel and the second panel connecting device connected to one another.
Further, the material of described the first panel and the second panel is epoxy resin.
Further, described Sound-proof material is that poly-ester fibres is cotton.
Further, the cross section of described sound insulation unit is a kind of in circular, rectangle or polygon.
Further, described connecting device is arranged on the plug on the first panel and is arranged on the slot on the second panel.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, can be in not obvious increase vehicle weight and cost, effectively reduce automotive interior noise, do not change original car panel structure, process for machining and manufacturing is constant, only increasing by a procedure can realize, tooling cost is low, and panel construction is simple, quick detachable, easy to maintenance, more can be by changing the inner sound isolation layer material soundproof effect of upgrading.Use body insulation not produce objectionable impurities, Environmental Safety.

The specific embodiment
As shown in Figure 1, the invention provides a kind of auto sound panel, comprise the first panel 1, the second panel 2 and be arranged on the first panel and the second panel between Sound-proof material 4, on described the first panel, be provided with keel 3, wherein: described keel 3 and the first panel 1 are single injection-molded, described keel 3 form grating texture crisscrossly, each trellis forms a sound insulation unit 5 with hollow structure, described Sound-proof material 4 is filled in described sound insulation unit 5, also comprise by described the first panel 1 and the second panel 2 connecting device 8 connected to one another, as shown in Figure 2.
The material of described the first panel 1 and the second panel 2 is for being epoxy resin.
Described Sound-proof material 4 is that poly-ester fibres is cotton.
The cross section of described sound insulation unit 5 is a kind of in circular, rectangle or polygonal cross-section.
Described connecting device 8 is arranged on the first panel 1 plug 6 and is arranged on the slot 7 on the second panel 2.
The working process of this example: install after fixing use in the present invention, if there is damaging or other reasons need to be changed Sound-proof material, or the Sound-proof material material of upgrading promotes soundproof effect, can be by the first panel and the second panel connecting device connected to one another be opened, sound insulation unit is exposed, after changing Sound-proof material, again connecting device is installed again to repeated usage.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
