Description

Engine bonnet silencing pad
Technical field
The present invention relates to automotive interior gadget technical field, be specifically related to a kind of engine bonnet silencing pad.
Background technology
Along with the development of science and technology, improving constantly of people's living standard, the pursuit of people to life not only rests on material base, and what more take notice of is that spiritual one is enjoyed and pursued.Along with the arrival in private car epoch, the standard of quality that what people focused on more is, people are when selecting to buy private car, and a kind of especially of emphasis can bring comfortable high standard performance.At present, the driving engine of the private car of higher gears is all equipped with engine bonnet silencing pad, because driving engine can produce noise pollution in the course of the work, affect the mood outputing mood comfort level and motroist and the comfort level of navigating mate, even affect the quality of life of surrounding population.But the sound insulation silencing pad ubiquity sound-insulation effect of existing engine bonnet is bad, heat radiation is slow waits deficiency.Therefore, need to improve a kind of new scheme to solve.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of sound insulation good muffling effect, rapid heat dissipation, the engine bonnet silencing pad of long service life.
Technical matters to be solved by this invention realizes by the following technical solutions:
Engine bonnet silencing pad, it comprises silencing pad body, it is characterized in that: the upper surface of described silencing pad body is processed with five bossings, and five bossings are also symmetrically arranged with in the lower surface of described silencing pad, the upper surface of described silencing pad body is also processed with center hole clipping, the bottom edge place of described silencing pad body is processed with some breach, and described silencing pad body upper surface is also processed with five little hole clippings.
As preferred embodiment, described in be positioned at silencing pad body edge surrounding be evenly processed with some bloops.
As preferred embodiment, described in be positioned at silencing pad body lower surface bossing on be all processed with wave groove.
As preferred embodiment, described silencing pad body comprises aluminium foil layer, carbon fiber layer, nonwoven layer, Fiber mat layer, and wherein, described aluminium foil layer is positioned at the inner surface of silencing pad body.
As preferred embodiment, the Thickness Design of described aluminium foil layer is 0.2-0.5mm.
Further, the large I of shape and size of described silencing pad body designs according to the concrete shape of vehicle motor interior surface intermediate groove and size.
Further, the height of described breach designs as the case may be, and the skin area being positioned at the bossing of silencing pad body lower surface is generally designed to the 30%-60% of internal surface area.
The invention has the beneficial effects as follows:
1) at utmost can reduce the noise that driving engine produces, better more comfortable riding and running environments is provided;
2) there is good heat sinking function, extend the service life of driving engine;
3) prevent dust particles from entering driving engine, cause not necessary damage and economic loss;
4) there is aesthetic value, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic cross-section of the present invention;
In figure: 1-silencing pad body; 2-bossing; 3-wave groove; 4-center hole clipping; The little hole clipping of 5-; 6-breach; 7-bloop; 8-Fiber mat layer; 9-nonwoven layer; 10-carbon fiber layer; 11-aluminium foil layer.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1-2, engine bonnet silencing pad, it comprises silencing pad body 1, the upper surface of silencing pad body 1 is processed with five bossings 2, and five bossings 2 are also symmetrically arranged with in the lower surface of silencing pad body 1, bossing 2 makes to leave gap between silencing pad body 1 and the contact surface of engine bonnet, is convenient to the blocking-up of noise, is convenient to distributing of heat simultaneously; The upper surface of silencing pad body 1 is also processed with center hole clipping 4, and center hole clipping 4 is for fixing silencing pad body 1; The bottom edge place of silencing pad body 1 is processed with some breach 6, for blocking noise, reaches aesthetic simultaneously; Silencing pad body 1 upper surface is also processed with five little hole clippings 5, for fixing silencing pad body 1, strengthens steadiness.
The edge surrounding being positioned at silencing pad body 1 is evenly processed with some bloops 7, strengthens resistance sound soundproof effect.
The bossing 2 being positioned at silencing pad body 1 lower surface is all processed with wave groove 3, strengthens soundproof effect further and accelerate heat and distribute, increasing service life of engine.
Silencing pad body 1 comprises aluminium foil layer 11, carbon fiber layer 10, nonwoven layer 9, Fiber mat layer 8, and wherein, aluminium foil layer 11 is positioned at the inner surface of silencing pad body 1, is the material of high-quality, and have good soundproof effect, heat radiation function, cost is low, economic environmental protection.
The Thickness Design of aluminium foil layer 11 is 0.2-0.5mm, is convenient to reach best sound insulation and radiating effect.
The large I of shape and size of silencing pad body 1 designs according to the concrete shape of vehicle motor interior surface intermediate groove and size, is convenient to promote the use of.
The height of breach 6 designs as the case may be, and the skin area being positioned at the bossing 2 of silencing pad body 1 lower surface is generally designed to the 30%-60% of internal surface area, is convenient to promote the use of and reach sound insulation to the full extent and radiating effect.
More than show and describe groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
