차량의 흡음재 조립구조{sound-absorbing materials bolting structure in a car}Sound-absorbing materials bolting structure in a car}

본 발명은 차량의 흡음재 조립구조에 관한 것으로, 보다 상세하게는 흡음재의 유동을 방지하기 위해 차량의 바디패널에 일체로 형성된 수나사와 체결부를 치합함으로써 조립 설치를 용이하게 할 수 있는 차량의 흡음재 조립구조에 관한 것이다.The present invention relates to a sound absorbing material assembling structure of a vehicle, and more particularly to a sound absorbing material assembling structure of the vehicle that can facilitate the assembly installation by joining the male screw and the fastening portion integrally formed in the body panel of the vehicle to prevent the flow of the sound absorbing material. It is about.

일반적으로 자동차를 주행함에 있어서는 쾌적한 실내 환경을 유지하기 위하여 정숙성을 요망하고 있다.In general, in driving a car, quietness is required to maintain a comfortable indoor environment.

이와 같은 정숙성은 차량의 차 외부에서 발생되는 소음을 차단하는 것이라 할 것이다.Such quietness is to block the noise generated from the outside of the vehicle.

따라서, 차량의 외형을 이루는 바디패널에 흡음재를 부착하여 외부의 소음이 내부로 유입되는 것을 차단하고 있다.Therefore, by attaching a sound absorbing material to the body panel forming the outer appearance of the vehicle to block the outside noise from entering.

도 1에 도시한 바와 같이, 차량의 바디패널(body panel,10) 전면에는 폴리우레탄 계열의 흡음재(12)가 부착 설치된다.As shown in FIG. 1, a polyurethane-based sound absorbing material 12 is attached to a front surface of a body panel 10 of a vehicle.

상기 흡음재(12)가 바디패널(10) 상에서 요동되지 않도록 볼트(22)와 너트(24)로 체결하게 된다.The sound absorbing material 12 is fastened to the bolt 22 and the nut 24 so that the sound absorbing material 12 does not rock on the body panel 10.

이때, 상기 바디패널(10)에는 다수개의 제 1설치공(11)이 일정하게 통공 형성되어 있다.At this time, the body panel 10 has a plurality of first installation holes 11 are formed through the constant.

그리고, 상기 바디패널(10)의 전면에 설치될 흡음재(12)에는 제 1설치공(11)과 일치되는 제 2설치공(13)이 형성되어 있다.In addition, the sound absorbing material 12 to be installed on the front surface of the body panel 10 is formed with a second installation hole 13 that matches the first installation hole 11.
