Description
본 발명은 자동차용 언더커버 장착구조에 관한 것으로서, 보다 상세하게는 자동차의 공력성능을 향상시키기 위하여 자동차의 플로워패널 하부에 설치되는 언더커버의 장착구조를 개선시킨 자동차용 언더커버 장착구조에 관한 것이다.The present invention relates to an undercover mounting structure for an automobile, and more particularly, to an undercover mounting structure for an automobile having an improved undercover mounting structure installed under a floor panel of an automobile to improve aerodynamic performance of the automobile. .
일반적으로, 자동차는 주행할 때 차체가 대기중의 공기와 충돌하게 됨으로써 공기저항력을 받게 되는데 이 공기저항력은 크게 항력과 양력으로 나뉜다.In general, when a vehicle is driven, the vehicle body is subjected to air resistance by colliding with air in the air, which is divided into drag and lift.
여기서 항력이란 주행 중에 공기와 직접 충돌되는 차체가 주행의 반대방향으로 받는 저항력을 말하고, 양력이란 주행중의 차체 상부와 하부에서 발생되는 압력차이로 차체가 뜨게 되는 현상을 말한다.Here, drag refers to a resistance force received by the vehicle body collided directly with the air while driving, and lift means a phenomenon in which the vehicle body floats due to a pressure difference generated in the upper and lower parts of the vehicle while driving.
따라서, 자동차 개발 초기단계에서 이러한 공기저항력을 최대한 저감시키고자 목표 공기저항계수를 정해놓고 그 목표를 달성하기 위해 여러 차례의 시뮬레이션과 풍동실험을 수행하면서 차체 형상을 결정한다.Therefore, in order to reduce the air resistance as much as possible in the early stage of automobile development, the target air resistance coefficient is determined and the body shape is determined by performing several simulations and wind tunnel tests to achieve the target.
한편, 기본적인 차체 형상이 결정된 다음에도 항력과 양력을 저감시킴으로써 공력성능을 향상시키기 위한 여러 가지 수단이 제공되는데, 그 중의 하나가 자동차의 하부에 언더커버를 설치하는 것이다.On the other hand, even after the basic body shape is determined, various means for improving aerodynamic performance by reducing drag and lift are provided, one of which is to install an undercover at the bottom of the vehicle.
자동차의 하부에는 배기관을 포함한 각종 부품이 설치되어 있어서 자동차의 하부 바닥면을 이루는 플로워패널이 굴곡과 복잡한 형상을 갖게 되고, 이 때문에 차체 하부로 대량의 공기가 유입되게 되면 플로워패널에서 와류가 발생된다.Various parts including exhaust pipes are installed in the lower part of the car, so the floor panel forming the lower floor of the car has a curved shape and a complicated shape. Therefore, when a large amount of air flows into the lower part of the vehicle, vortices are generated in the floor panel. .
따라서, 자동차의 플로워패널 하부를 매끈한 패널로 커버함으로써 공력성능이 향상될 수 있도록 하는데 종래에는 도1 및 도2에 도시된 바와 같이, 플로워패널(10) 하부면에는 다수개의 마운팅브래킷(11)이 돌출되게 설치되고, 상기 마운팅브래킷(11)에는 체결용 너트(11a)가 일체로 설치되어 있다.Therefore, the aerodynamic performance can be improved by covering the lower portion of the floor panel of the vehicle with a smooth panel. Conventionally, as shown in FIGS. 1 and 2, a plurality of mounting brackets 11 are provided on the lower surface of the floor panel 10. Protrudingly installed, the mounting bracket 11 is integrally provided with a fastening nut 11a.
또한, 상기 플로워패널(10)의 하부를 커버하기 위하여 상기 마운팅브래킷(11)과 접촉되는 언더커버(20)가 마련된다. 상기 언더커버(20)는 상기 마운팅브래킷(11)에 결합되기 위하여 상기 마운팅브래킷의 너트(11a)에 체결되는 볼트(b)가 언더커버(20)의 하부에서 끼워진다.In addition, an under cover 20 in contact with the mounting bracket 11 is provided to cover the lower portion of the follower panel 10. The under cover 20 is fitted with a bolt (b) fastened to the nut (11a) of the mounting bracket to be coupled to the mounting bracket 11 in the lower portion of the under cover (20).
그러나, 상술한 바와 같은 종래의 언더커버 장착구조에서는 언더커버(20)를 플로워패널의 마운팅브래킷(11)에 고정시키기 위한 볼트(b)가 상기 언더커버(20) 하부면에 돌출되는 구조를 갖게 됨으로써 자동차가 주행하다가 차체의 하부가 도로 노면과 닿게 되면 언더커버(20) 상에 돌출된 볼트(b)가 노면과 닿아 소음이 발생되거나 심한 경우에는 볼트(b)가 파손되어 언더커버(20)의 마운팅이 불량해지는 문제가 생긴다.However, in the conventional undercover mounting structure as described above, the bolt b for fixing the undercover 20 to the mounting bracket 11 of the floor panel has a structure that protrudes from the lower surface of the undercover 20. When the vehicle is driven while the lower part of the vehicle comes into contact with the road surface, the bolts (b) protruding on the undercover (20) come into contact with the road surface, and noise is generated. Problem of poor mounting.
또한, 종래의 언더커버 장착구조에서는 언더커버(20)를 플로워패널(10) 하부에 장착하기 위하여 마운팅브래킷(11)과 너트(11a) 및 볼트(b)가 필요하므로 그에 따른 작업공정수가 많고 부품비용이 많이 드는 문제점이 있다.In addition, in the conventional undercover mounting structure, a mounting bracket 11, a nut 11a, and a bolt b are required to mount the undercover 20 under the floor panel 10. There is a costly problem.
본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적은 자동차의 플로워패널 하부에 장착되는 언더커버 상으로 어떠한 부품도 돌출되지 아니하며 언더커버 장착에 따른 부품수 및 장착공정수를 줄이기 위함에 있다.The present invention has been proposed in order to solve the above problems, the object of which is that no parts protrude onto the undercover mounted on the floor panel of the vehicle and reduce the number of parts and the number of mounting process according to the undercover installation. For sake.
