Abstract
The utility model relates to a type of making an uproar sheath falls for car, include the rubber spare of the intercalary band sound insulating cavity body and install the internal sound insulation sponge at sound insulating cavity, during the sound insulating cavity that installs sound insulation sponge at rubber spare through the expansion to rubber spare is internal, when the noise will be through the sheath, except that the cavity formula structure of rubber spare itself can weaken the noise, the sound insulation sponge noise reduction further that embeds. Compared with the prior art, the utility model has the advantages of better noise resistance.
Description
Technical field
The utility model is related to a kind of sheath, more particularly, to a kind of noise reducing type sheath for automobile.
Background technology
In China, the competition of automobile product is fierce all the more, how to improve the competitiveness of automobile, how meeting consumption
The various demands of person, are problem of each main engine plants in thinking.It is current using innovative technology, raising quality, raising comfort level
Three directions of automobile market.Previous decade Chinese automobile is particularly independent brand automobile, may ignore NVH performances, and car exists
Car wind is made an uproar just very greatly when 100 kilometers of speed per hours per hour are reached on road, and this kind of situation can not meet customer demand, in order to full
The requirement of sufficient consumer, car load NVH values can only be dropped under certain decibel.
Existing sheath is all gum structure, as long as by the wall thickness of sheath come noise reduction, DeGrain.Current city
Client reduces noise requirements more and more higher for in-car on field, based on this, needs a kind of process is simple, better performances simultaneously can have
More preferable decrease of noise functions jacket structure.
Utility model content
The purpose of this utility model is exactly the defect in order to overcome above-mentioned prior art to exist and provides a kind of for automobile
Noise reducing type sheath.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of noise reducing type sheath for automobile, including Intermediate Gray sound insulation cavity rubber parts and installed in sound insulation cavity
Interior sound-isolating sponge；
During by the expansion to rubber parts sound-isolating sponge is arranged in the sound insulation cavity of rubber parts, when noise will pass through
During sheath, in addition to the cavity type structure of rubber parts itself can weaken noise, built-in sound-isolating sponge further reduces noise.
Described rubber parts is followed successively by shirt rim, main framing, pipe portion and cable-through hole by outer rim to middle part, in described main framing
Sound insulation cavity is formed between surface and pipe portion outer surface.
Changeover portion is provided between described main framing and shirt rim.
Described main framing is convex structure, and it is integrally formed with pipe portion.
Described sound-isolating sponge is cirque structure, and center hole loads in sound insulation cavity after being set in pipe portion.
Described sound insulation inside cavity is provided with the support column for supporting sound-isolating sponge.
Compared with prior art, the utility model has advantages below：
1st, it is universal：This structure can be applicable to vehicle body diverse location the sheath of noise reduction requirement, with generally applicable property.
2nd, it is preferably noise reduction：The sheath that the cavity type structure and built-in sponge structure of this structure make has more preferable noise reduction work(
Energy.
3rd, simple structure, easy to assembly：Using rubber parts and sound-isolating sponge be directly sleeved on part by use.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structural representation of the utility model with sound-isolating sponge.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is a part of embodiment of the present utility model, rather than all implement
Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of creative work is not made
The every other embodiment for obtaining, should all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of noise reducing type sheath for automobile, including the rubber parts 1 of Intermediate Gray sound insulation cavity with
And the sound-isolating sponge 2 in sound insulation cavity 3；
The structure of rubber parts design when in the middle of formed a sound insulation cavity body structure, can make noise cavity tie
Appropriate decrease is obtained in structure simultaneously, has the space can be with security protection sound-isolating sponge.
During by the expansion to rubber parts 1 sound-isolating sponge 2 is arranged in the sound insulation cavity 3 of rubber parts, when noise will
During by sheath, in addition to the cavity type structure of rubber parts itself can weaken noise, built-in sound-isolating sponge is further reduced
Noise.
Described rubber parts 1 is followed successively by shirt rim 11, main framing 12, pipe portion 13 and cable-through hole 14 by outer rim to middle part, described
The inner surface of main framing 12 and the outer surface of pipe portion 13 between formed sound insulation cavity.It is provided between described main framing 12 and shirt rim 11
Changeover portion 15.Described main framing 12 is convex structure, and it is integrally formed with pipe portion.Described sound-isolating sponge is annular knot
Structure, center hole loads in sound insulation cavity after being set in pipe portion.Described sound insulation inside cavity is provided with for supporting sound insulation sea
Continuous support column.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any those familiar with the art can readily occur in various in the technical scope that the utility model is disclosed
Equivalent modification or replacement, these modifications or replace all should be covered within protection domain of the present utility model.Therefore, this practicality
New protection domain should be defined by scope of the claims.
