본 발명은 엔진룸의 하부에 장착되는 언더커버에 관한 것으로서, 더욱더 상세하게는 차량을 운행 시 엔진룸에 설치되어 있는 엔진의 하부면이 노면의 돌출부에 접촉되지 않도록 함과 동시에 고속으로 운행 시에는 엔진룸의 하부로 주행풍이 유입되어 엔진이 냉각되도록 하는 차량 엔진룸의 언더커버에 관한 것이다.The present invention relates to an undercover mounted to a lower part of an engine room. More particularly, the lower cover of an engine installed in an engine room does not come into contact with a protrusion of a road surface while driving a vehicle. It relates to an undercover of a vehicle engine room for driving wind flows into the lower part of the engine room to allow the engine to cool.

통상 우천 또는 강설중이나 비가 갠 뒤에 주행을 하면 고속으로 회전하는 타이어에 의해 분산되는 오수 또는 눈의 일부는 미세한 분무로 변해 차체 측면이나 차체 밑면의 기류를 타고 옮겨진다.In general, when driving in rain or snow, or after rain, some of the sewage or snow, which is dispersed by the tires rotating at high speed, is turned into fine sprays and is carried by the airflow at the side of the body or under the body.

그리고 먼지가 많은 건조로를 주행하는 경우에는 우천의 경우와 같이, 타이어에 의해 발생하는 먼지가 차체 후륜 등의 박리 영역에 부유해 차체 하면 및 후면에 부착된다.When driving through a dusty drying furnace, as in the case of rain, dust generated by tires floats in the peeling area such as the rear wheel of the vehicle body and adheres to the lower surface and the rear surface of the vehicle body.

이와 같이 주행 중 노면의 흙탕물이나 먼지 및 그밖에 돌조각 등이 엔진룸에 침투하여 엔진룸에 설치된 엔진을 비롯하여 와이어링하니스 또는 이와 연결된 커넥터 등에 부착되어서 기관의 작동에 악영향을 미치게 하거나 부속품의 수명을 단축시키게 된다.In this way, muddy water, dust and other fragments of the road surface penetrate the engine room and are attached to the wiring harness or the connector connected to the engine installed in the engine room to adversely affect the operation of the engine or to shorten the life of accessories. do.

특히 주행중 학교, 아파트 등의 주택단지 근처 도로 노면에 설치한 과속방지용 돌출턱 및 돌부리 등에 의해 엔진룸의 하부가 접촉되는 경우 차체가 일그러지거나 심한 경우 파손되었다.In particular, when the lower part of the engine room is in contact with the speed bumps and bevels, which are installed on the road surface near the housing complex such as schools and apartments, the vehicle body is distorted or severely damaged.

따라서 이와 같이 돌조각 등이 엔진룸에 침투하는 것을 원천적으로 차단하거나 노면의 돌출부에 엔진룸의 하부가 접촉되지 않도록 엔진룸의 하부에는 얇은 철판으로 된 언더커버를 장착시키고 있다. Therefore, the under cover made of a thin iron plate is installed at the lower part of the engine room so that the stone fragments, etc., are inherently blocked from penetrating the engine room or the lower part of the engine room does not come into contact with the protrusion of the road surface.

이와 같은 언더커버는 자동차의 전면에 형성된 엔진룸의 하부에 위치되도록 Such an undercover is located under the engine room formed in the front of the vehicle.

엔진룸을 형성하고 있는 차체에 단부가 보울트 체결되어, 차량을 운행 시 노면에 설치된 돌출부에 엔진룸에 설치되어 있는 엔진의 하부가 접촉되지 않도록 함 과 동시에 상기 엔진이 설치되어 있는 엔진룸의 내부로 흙탕물 등과 같은 이물질이 유입되지 않게 되는 것이다.An end is bolted to the vehicle body forming the engine room, so that the lower part of the engine installed in the engine room does not come into contact with the protrusion provided on the road surface while driving the vehicle and at the same time into the engine room where the engine is installed. Foreign matters such as muddy water will not be introduced.

그러나, 이러한 종래의 언더커버는 엔진룸의 하부를 막아 주행 중 바람이 엔진룸으로 유입되는 것을 차단되므로 엔진이 과열되었을 때 엔진을 효율적으로 냉각시키지 못하는 문제점이 있었다.However, since the conventional undercover blocks the lower part of the engine room and blocks the wind from entering the engine room while driving, there is a problem in that the engine cannot be cooled efficiently when the engine is overheated.

한편, 종래에도 상기와 같은 문제점을 해결하기 위해 언더커버에 수개의 공기홀을 관통되게 형성시켜, 차량을 운행 시 과열되는 엔진이 냉각되도록 하고 있다.On the other hand, in order to solve the above problems in the prior art by forming a plurality of air holes in the undercover, so that the engine is overheated when the vehicle is running.
