Compared with the prior art, the utility model discloses on being fixed in the automobile body panel beating, in effectively filling the great space that exists between preceding panel beating outer oil pipe and the engine to block the too much heat that comes from the engine production by high temperature resistant aluminium foil, let the vibration isolator effectively exert sound absorption vibration isolation effect, reach further improve and improve thermal-insulated, vibration isolation, sound insulation, shock attenuation in the automobile cabin, fall the purpose of making an uproar.
Description
Technical Field
The utility model relates to a vibration isolator especially relates to a preceding outer vibration isolator of enclosing.
Background
Along with the development of the automobile industry, the requirements of people on safety, comfort and environmental protection of automobiles are higher and higher, and the standard requirements on sound insulation, vibration isolation, corrosion prevention and noise prevention in automobile cabins are also continuously improved. At present, automobile engineering technicians perform sound insulation and vibration isolation technical upgrading on vehicle vibration dampers, sound insulation and heat insulation pads, sound insulation in automobiles, vibration isolation carpets, automobile body pasting glass, automobile roofs and the like in automobiles, so that vibration and noise in automobile cabins are effectively improved. However, at present, the three-cylinder machine is adopted in a large number of automobiles, and the three-cylinder machine generates more heat compared with the traditional four-cylinder machine, so that the vibration isolation pad outside the front wall bears more heat energy, the vibration isolation pad can not completely isolate the heat energy, the heat energy is transferred into the automobile, the heat energy can not effectively reach the requirements of heat insulation, vibration isolation and sound absorption, and the technical problem is not well solved all the time.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a front wall outer vibration isolation pad for overcoming the defects of the prior art.
The purpose of the utility model can be realized through the following technical scheme:
The front wall outer vibration isolation pad comprises a vibration isolation pad body and an aluminum foil covering the vibration isolation pad body.
Further, the vibration isolation pad body comprises a first non-woven fabric layer, a light PU layer and a second non-woven fabric layer from outside to inside in sequence.
Furthermore, the aluminum foil is provided with a back adhesive, so that the adhesion degree is increased, and the fixation is facilitated.
Furthermore, be provided with recess and arch on the aluminium foil, can produce diffuse reflection to sound wave and heat radiation, effectively prevent that the energy from concentrating.
Furthermore, the thickness of aluminium foil is 0.6mm, and is lighter.
Furthermore, the aluminum foil is further provided with through holes for part installation requirements and positioning, and the shock insulation pad is convenient to install and position.
Further, the first nonwoven fabric layer and the second nonwoven fabric layer The areal density of the two non-woven fabric layers is 90-100g/m 2。
Furthermore, the vibration isolating pad is fixed on a stud of a metal plate of the vehicle body through a clamp, and a larger gap between the metal plate and the oil pipe and between the metal plate and the engine is effectively filled.
The high-temperature-resistant aluminum foil blocks excessive heat generated by an engine, and the vibration isolation pad effectively plays a sound absorption and vibration isolation role, so that the aims of improving and improving sound insulation, heat insulation, vibration reduction and noise reduction in the vehicle are fulfilled.
Compared with the prior art, the utility model discloses on being fixed in the automobile body panel beating, in effectively filling the great space that exists between preceding panel beating outer oil pipe and the engine to block the too much heat that comes from the engine production by high temperature resistant aluminium foil, let the vibration isolator effectively exert sound absorption vibration isolation effect, reach further improve and improve thermal-insulated, vibration isolation, sound insulation, shock attenuation in the automobile cabin, fall the purpose of making an uproar.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Examples
A vibration isolating pad for the front wall of a vehicle comprises a vibration isolating pad body and an aluminum foil 4 covering the vibration isolating pad body, as shown in figure 1. The vibration isolation pad body comprises a first non-woven fabric layer 1, a light PU layer 2 and a second non-woven fabric layer 3 from outside to inside in sequence. The aluminum foil 4 is provided with the back adhesive, so that the adhesion degree is increased, and the fixation is facilitated. The aluminum foil 4 is provided with the groove 6 and the protrusion 5, so that diffuse reflection effect can be generated on sound waves and heat radiation, and energy collection is effectively prevented In (1). The aluminum foil 4 is 0.6mm thick and is lighter. The aluminum foil 4 is further provided with a through hole, sound waves and vibration are transmitted to the vibration isolation pad main body, the vibration isolation effect is improved, and meanwhile, the vibration isolation pad is used for part installation requirements and positioning, and installation and positioning of the vibration isolation pad are facilitated. The first nonwoven fabric layer 1 and the second nonwoven fabric layer 3 have an areal density of 90 to 100g/m 2. As shown in FIG. 2, the vibration isolator is fixed on the stud of the vehicle body metal plate 8 through a clamp 7, and large gaps among the metal plate 8, the oil pipe and the engine are effectively filled. The high-temperature resistant aluminum foil 4 blocks excessive heat generated by an engine, and the vibration isolation pad effectively plays a sound absorption and vibration isolation role, so that the aims of improving and improving sound insulation, heat insulation, vibration reduction and noise reduction in the vehicle are fulfilled.
The embodiments described above are intended to facilitate the understanding and use of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications to these embodiments may be made, and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. Therefore, the present invention is not limited to the above embodiments, and those skilled in the art should make improvements and modifications within the scope of the present invention according to the disclosure of the present invention.
