본 고안은 차량의 엔진룸에 착설되어 엔진으로 부터 발생되는 진동 및 소음 등을 용이하게 차단시킬 수 있는 흡음 및 차음패드에 관한 것으로 이는 특히 알루미늄 포일(Al Foil)을 개재하여 폴리우레탄과 폴리에틸렌 발포층이 각각 형성된 패드 본체부를 시이트상으로 제작하여 차량의 엔진룸 내측으로 착설함으로써 차량의 엔진으로부터 발생되는 진동과 이에 따른 소음을 가일층 차단시킬 수 있도록 함은 물론, 차량의 철판진동을 억제함으로 인한 실내의 단열 및 정숙성을 향상시킬수 있도록한 차량의 흡음 및 차음패드에 관한 것이다.The present invention relates to a sound absorbing and sound insulating pad that can be easily installed in an engine room of a vehicle to easily block vibrations and noises generated from an engine, and is particularly a polyurethane and polyethylene foam layer through an aluminum foil. The pad body is formed in a sheet form and installed inside the engine room of the vehicle to further block the vibration and the noise generated from the engine of the vehicle, as well as to suppress the vibration of the steel plate of the vehicle. The present invention relates to a sound absorbing and sound insulating pad of a vehicle capable of improving insulation and quietness.

일반적으로 알려져 있는 버스 등과 같은 차량의 엔진룸 내측으로 설치되는 흡음 패드에 있어서는 제1도에 도시한 바와같이 알루미늄 포일(21) 상측에 섬유질층(22)이 적층 형성된 패드 본체부(23)를 시이트상으로 제작후, 이를 차량(24)의 엔진룸(25) 내측 철판의 벽면상에 스크류로서 착설시킨 구조로 이루어진다.In a sound absorbing pad installed inside an engine room of a vehicle such as a bus, which is generally known, as shown in FIG. 1, a pad main body portion 23 in which a fibrous layer 22 is laminated on an aluminum foil 21 is formed.

Alternatively, the pad body 23 itself may be configured as a polyurethane foam layer and used only as a single use to block noise generated from an engine. Therefore, the severe vibration generated from the engine room 25 of the vehicle 24 is transmitted as it is to the room as it is, the quietness of the room is greatly reduced, resulting in a number of problems, such as appearing as a major factor of noise generation.
