However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

도 4에 도시된 바와 같이, 본 발명에 따른 언더커버는 특히, 엔진룸 언더커버(100)는 차량의 공력개선, 흡음성 증대, 소음 감소 등의 목적으로 저중량의 LWRT(Low Weight Reinforced Thermoplastics) 소재를 채택하고 있으며, 엔진룸 하부를 전면 커버하는 형태로 전환되고 있다.As shown in FIG. 4, the under cover according to the present invention is particularly applicable to an engine room under cover 100 having a low weight reinforced thermoplastics (LWRT) material for the purpose of improving the aerodynamic performance of a vehicle, increasing sound absorption, And it is converted into a form that covers the bottom of the engine compartment.

이때, 상기 LWRT(Low Weight Reinforced Thermoplastics)는 열가소성수지에 글래스 화이버가 함침된 복합소재를 의미하며, 강도가 우수하여 저중량 설계가 가능하므로 두께를 얇게 하여 차량 경량화에 이바지함은 물론 내부에 기공층이 형성되어 있기 때문에 흡음특성도 향상시킬 수 있는 소재이다.The LWRT (Low Weight Reinforced Thermoplastics) refers to a composite material impregnated with a glass fiber in a thermoplastic resin. The LWRT (Low Weight Reinforced Thermoplastics) is a composite material impregnated with a glass fiber. So that the sound absorption characteristic can be improved.

통상, 차체의 엔진(EN)에는 오일필터(OF)와 오일드레인(OD)이 구비되며, 엔진룸 언더커버(100)의 이들 대응 부위는 절개된 상태로 따내어지고, 따내진 부위에는 별도로 제조된 커버(이하 '정비커버'라 함)가 조립된다.Normally, the engine EN of the vehicle body is provided with an oil filter OF and an oil drain OD, and these corresponding portions of the engine room under cover 100 are taken in an incised state, (Hereinafter referred to as " maintenance cover ") is assembled.

종래에는 이 정비커버가 오일필터 교환용 커버와 오일드레인 교환용 커버 2개로 나뉘어 제조된 후 각각 엔진룸 언더커버(100)에 조립되었으나, 본 발명에서는 나누지 않고 오일필터 교환용 커버와 오일드레인 교환용 커버가 하나로 된 일체형 정비커버(200)를 제공한다.In the related art, the maintenance cover is divided into an oil filter replacement cover and an oil drain replacement cover, and then assembled to the engine room under cover 100. In the present invention, however, the oil filter replacement cover and the oil drain replacement Thereby providing an integral maintenance cover 200 having a single cover.

이 경우, 상기 정비커버(200)는 엔진룸 언더커버(100)를 구성하고 있는 소재와 동일한 LWRT 소재로 제조되도록 하여 상호 이질감을 없애도록 구성된다.In this case, the maintenance cover 200 is made of the same LWRT material as the material of the engine room under cover 100, thereby eliminating the sense of heterogeneity.

특히, 상기 정비커버(200)는 차체 조립라인에서 조립성을 향상시키기 위해 상기 엔진룸 언더커버(100) 상에 조립된 상태로 이송되는데, 보통 도 5의 예시와 같이 정비커버(200)의 둘레를 따라 5-6개의 헥사 타입의 스크류(210)가 체결되게 된다.In particular, the maintenance cover 200 is transported in an assembled state on the engine room under cover 100 in order to improve the assemblability in the car body assembly line. Usually, the circumference of the maintenance cover 200 5 to 6 hexa-type screws 210 are fastened together.

그런데, 정비커버(200)가 체결된 상태로 엔진룸 언더커버(100) 다수개를 적층하여 이송하게 되면 이송과정에서 상기 스크류(210)에 의해 하측에 배치된 엔진룸 언더커버(100) 표면이 손상되는 스크래치 불량이 유발될 수 있어 제품 품질이 떨어지고, 클레임 사항이 된다.However, when a plurality of engine room under covers 100 are stacked and transported while the maintenance cover 200 is engaged, the surface of the engine room under cover 100 disposed at the lower side by the screw 210 during the transportation process Scratch defects may be caused to be damaged, resulting in poor product quality and being a claim.

이를 방지하기 위해, 본 발명에서는 엔진룸 언더커버(100)와 정비커버(200)가 접하면서 스크류(210)에 의해 체결되는 부위를 포밍하여 스크류(210)가 돌출되지 않게 함으로써 상기한 스크래치 불량을 미연에 방지하도록 구성된다.In order to prevent this, in the present invention, the engine room under cover 100 and the maintenance cover 200 are in contact with each other to form a portion to be fastened by the screw 210 to prevent the screw 210 from protruding, In order to prevent it from occurring.

즉, 상기 엔진룸 언더커버(100)에서는 하방향으로 요입되게 대략 'U' 형상의 엔진커버포밍부(F1)를 형성하고, 상기 정비커버(200)에서는 상방향으로 요입되게 대략 '∩' 형상의 정비커버포밍부(F2)를 형성하여 상호 맞대어지게 구성한 다음 이들을 관통하여 스크류(210)를 체결함으로써 스크류(210)가 포밍된 깊이 안에 갇히도록 하여 스크래치를 방지하도록 구성된다.That is, in the engine room under cover 100, an approximately U-shaped engine cover forming portion F1 is formed to be recessed in a downward direction, and in the maintenance cover 200, The cover cover forming portions F2 of the cover cover forming portions F2 are formed so as to face each other, and then the cover cover forming portions F2 are made to face each other. Then, the cover 210 is screwed into the screw 210 to be trapped in the formed depth to prevent scratches.

다시 말해, 상기 엔진커버포밍부(F1) 및 정비커버포밍부(F2)의 포밍 깊이는 상기 스크류(210)의 길이보다 커야 한다.In other words, the forming depths of the engine cover forming section F1 and the cover forming section F2 must be greater than the length of the screw 210. [

뿐만 아니라, 상기 스크류(210)의 하단부 둘레에는 탄성편부(212)를 구성하고, 상기 탄성편부(212)와 간격을 두고 스크류(210)의 외주면에는 밀폐편부(214)를 더 구성하여 상기 스크류(210) 체결시 상기 엔진커버포밍부(F1)와 정비커버포밍부(F2)가 상기 탄성편부(212)와 밀폐편부(214) 사이에 배치되게 조립함으로써 조립부 주변의 기밀성도 유지하도록 하면 더욱 좋다.The elastic piece portion 212 is formed around the lower end of the screw 210 and the sealing piece portion 214 is formed on the outer peripheral surface of the screw 210 with an interval from the elastic piece portion 212, The engine cover forming portion F1 and the maintenance cover forming portion F2 may be assembled so as to be disposed between the elastic piece portion 212 and the sealing piece portion 214 so as to maintain airtightness around the assembly portion .

특히, 상기와 같이 포밍부를 구성하게 되면 도 6의 예시와 같이, 정비커버(200)가 부착된 상태로 엔진룸 언더커버(100)를 이송할 때, 엔진룸 언더커버(100)를 서로 포개어 적층시킨 상태로 이송하더라도 스크류(210)는 포밍부 안에 위치하게 되어 엔진룸 언더커버(100)는 물론 정비커버(200), 스크류(210)들 끼리도 서로 닿지 않게 되어 표면 스크래치가 완전히 방지되므로 고품질의 언더커버를 구현할 수 있게 된다.6, when the engine room under cover 100 is transported with the maintenance cover 200 attached thereto, the engine room under cover 100 is superimposed on each other, The screw 210 is positioned in the forming portion so that the maintenance cover 200 and the screws 210 as well as the engine room under cover 100 are not contacted with each other and the surface scratch is completely prevented. The cover can be implemented.

덧붙여, 정비커버(200)의 둘레 중 일부, 더 정확하게는 차체에 고정되지 않고 엔진룸 언더커버(100) 하고만 체결되는 부분을 제외한 나머지 둘레부는 상기 엔진룸 언더커버(100)를 관통함과 동시에 차체에 고정되도록 구성됨이 바람직하다.In addition, a part of the circumference of the maintenance cover 200, more precisely, the circumferential portion excluding the portion which is not fixed to the vehicle body but is engaged only by the engine room under cover 100 penetrates the engine room under cover 100 It is preferable to be configured to be fixed to the vehicle body.

즉, 엔진룸 언더커버(100)와 동시에 차체 또는 샤시품에 체결되는 것으로 이는 당연하다 하겠다.
That is, it is a matter of course that the engine room under cover 100 is fastened to the vehicle body or the chassis at the same time.
