Abstract
A kind of car intrinsic motivation hatchcover sealing denoising structure, comprise engine compartment cover, the cotton layer of sound-insulating and heat-insulating and cabin seam sealing joint strip, the cotton layer uniform spreading of described sound-insulating and heat-insulating is located on machinery space interior surface, described cabin seam sealing joint strip is arranged on the periphery of machinery space, it is characterized in that: between the sidewall and the cotton layer of sound-insulating and heat-insulating of described engine compartment cover, be provided with a circle sealing layer; Described sealing layer and cabin seam sealing joint strip close contact, make machinery space seal.The utility model is by increasing by a circle glass fibre reinforced plastic structure in engine compartment cover inner peripheral, the contact of engine compartment cover and sealing joint strip is made to form firmly-soft contact, contact more closely near and can not be out of shape, make effect noise reduction in car better, the circle glass fibre reinforced plastic structure set up also can increase the intensity of engine compartment cover.
Description
Technical field
The utility model relates to automotive field, particularly a kind of car intrinsic motivation hatchcover sealing denoising structure.
Background technology
Preposition minibus engine position, in car, especially on the right side of chaufeur, if sealing effectiveness bad meeting in car intrinsic motivation cabin causes noise in larger car, has a strong impact on the ride comfort sense of chaufeur and passenger; Existing car intrinsic motivation cabin hermetically-sealed construction realizes sealing by the contact between engine compartment cover and machinery space seam sealing joint strip, and engine compartment cover structure is that glass-felt plastic covers skin directly inner side stickup sound-insulating and heat-insulating cotton realization sealing, but noise reduction is not good.Inside engine compartment cover, Sound-proof material directly contacts with machinery space sealing joint strip, is equivalent to soft-soft contact, and after distortion, Sound-proof material not easily restores to the original state, and easily produces gap, cause sealing effectiveness to decline when causing again sealing, and soundproof effect is deteriorated.
Utility model content
Technical matters to be solved:
The utility model, for above-mentioned defect, provides a kind of and reduces noise in F/F minibus car, increases the car intrinsic motivation hatchcover sealing denoising structure of the intensity of engine compartment cover simultaneously.
Technical scheme:
In order to realize above function, the utility model provides a kind of car intrinsic motivation hatchcover sealing denoising structure, comprise engine compartment cover, the cotton layer of sound-insulating and heat-insulating and cabin seam sealing joint strip, the cotton layer uniform spreading of described sound-insulating and heat-insulating is located on machinery space interior surface, described cabin seam sealing joint strip is arranged on the periphery of machinery space, it is characterized in that: between the sidewall and the cotton layer of sound-insulating and heat-insulating of described engine compartment cover, be provided with a circle sealing layer; Described sealing layer and cabin seam sealing joint strip close contact, make machinery space seal.
Further, described sealing layer is divided into gusset and the end to enclose, and gusset is arranged on the inner side of engine compartment cover, parallel with the sidewall of engine compartment cover, and the sidewall connecting gusset and engine compartment cover is enclosed at the described end, makes the sidewall along engine compartment cover form a vacuum ring.
Preferred as one, described sealing layer is glass steel material.
Further, the lower surface of the cotton layer of described sound-insulating and heat-insulating is also provided with Sound-proof material layer.
Further, described Sound-proof material layer is tinfoil paper+PE body insulation, and this Sound-proof material is directly adhesive in inner side sound insulation heat insulation foam layer and periphery one encloses on glass-felt plastic.
Beneficial effect:
The sealing denoising structure that the utility model provides is by increasing by a circle glass fibre reinforced plastic structure in engine compartment cover inner peripheral, the contact of engine compartment cover and sealing joint strip is made to form firmly-soft contact, contact more closely near and can not be out of shape, namely make adhesive tape be out of shape also easily to recover, make effect noise reduction in car better, reduce 2 decibels by the other noise of noise tester actual measurement chaufeur ear.The circle glass fibre reinforced plastic structure set up also can increase the intensity of engine compartment cover.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the overall schematic of engine compartment cover;
Fig. 2 is the structural representation of the engine compartment cover section adopted in prior art;
The structural representation of a kind of car intrinsic motivation hatchcover sealing denoising structure section that Fig. 3 provides for the utility model;
Wherein, 1-engine compartment cover, the cotton layer of 2-sound-insulating and heat-insulating, 3-cabin seam sealing joint strip, 4-Sound-proof material layer, 5-sealing layer.
Detailed description of the invention
The utility model provides a kind of car intrinsic motivation hatchcover to seal denoising structure, and for making the purpose of this utility model, technical scheme and effect clearly, clearly, and further describe the utility model with reference to accompanying drawing examples.Should be appreciated that concrete enforcement described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of car intrinsic motivation hatchcover sealing denoising structure, comprise engine compartment cover 1, the cotton layer 2 of sound-insulating and heat-insulating and cabin seam sealing joint strip 3, cotton layer 2 uniform spreading of described sound-insulating and heat-insulating to be located in engine compartment cover 1 on the surface, described cabin seam sealing joint strip 2 is arranged on the periphery of machinery space, it is characterized in that: between the sidewall and the cotton layer 2 of sound-insulating and heat-insulating of described engine compartment cover 1, be provided with a circle sealing layer 5; Described sealing layer 5 and cabin seam sealing joint strip 3 close contact, make machinery space seal.
Further, described sealing layer 5 is divided into gusset and the end to enclose, and gusset is arranged on the inner side of engine compartment cover, parallel with the sidewall of engine compartment cover, and the sidewall connecting gusset and engine compartment cover 1 is enclosed at the described end, makes the sidewall along engine compartment cover 1 form a vacuum ring.
Preferred as one, described sealing layer 5 is glass steel material.
Further, the lower surface of the cotton layer 2 of described sound-insulating and heat-insulating is also provided with Sound-proof material layer 4.
Further, described Sound-proof material layer 4 is tinfoil paper+PE body insulation, and this Sound-proof material layer 4 is directly adhesive in inner side sound insulation heat insulation foam layer and periphery one encloses on glass-felt plastic.
This sealing denoising structure that the utility model provides is by increasing by a circle glass fibre reinforced plastic structure in engine compartment cover inner peripheral, it is cotton that nexine pastes sound-insulating and heat-insulating, skin is close to one deck Sound-proof material again, not only can increase the intensity of hatchcover, and make the contact of machinery space sealing joint strip and engine compartment cover tightr, as described in Figure 3, be firmly a kind of-soft way of contact, even if adhesive tape distortion also easily recovers, make effect noise reduction in car better.2 decibels are reduced by the other noise of noise tester actual measurement chaufeur ear.
Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the utility model.
