Description

차량용 프론트범퍼Car Front Bumper

본 고안은 차량용 프론트범퍼에 관한 것으로, 특히 프론트범퍼페이시어의 형상을 변경하고 하단에 플랜지부를 형성하여 프론트범퍼가 차량 보디와 밀착될 수 있도록 함으로써, 프론트범퍼와 차체 사이의 공간에 공기가 유입되는 것을 방지하도록하여 차량의 주행성능이 향상 될 수 있게 한 것이다.The present invention relates to a vehicle front bumper, and in particular, by changing the shape of the front bumper facer and forming a flange portion at the bottom so that the front bumper can be in close contact with the vehicle body, air is introduced into the space between the front bumper and the vehicle body. It is to prevent the vehicle from being improved so that the driving performance of the vehicle can be improved.

일반적으로, 차량의 범퍼는 자동차가 다른 자동차 또는 물체에 충돌했을 경우, 보디의 손상을 경미하게 하는 것을 주목적으로 하고 있으며 자동차의 디자인에도 크게 관계하고 있다.In general, the bumper of a vehicle is mainly aimed at minimizing damage to the body when the vehicle collides with another vehicle or an object, and is also related to the design of the vehicle.

도1은 차량전면에 장착되는 프론트범퍼의 표면을 따라 흐르는 외부공기의 흐름을 나타낸 것으로서, 상기 프론트범퍼와 차량 보디사이에 소정의 공간이 형성되어 있으며 차량의 주행에 따라 차량전면의 공기가 프론트범퍼의 상하측으로 분리되어 차체를 따라 흐르게 된다.1 is a view illustrating a flow of external air flowing along a surface of a front bumper mounted on a front surface of a vehicle, in which a predetermined space is formed between the front bumper and the vehicle body, and the air on the front surface of the vehicle is driven by driving of the vehicle. It is separated by the upper and lower sides of the flow along the body.

그러나, 종래의 프론트범퍼에서는 프론트범퍼페이시어하부와 차체 사이가 밀착되지 않아 주행중 프론트범퍼와 차량보디 사이의 공간으로 외부의 공기가 유입되므로, 프론트범퍼 후측에서 와류가 발생하여 소음이 증가하고 차량의 주행성능을 저하시키며, 차체하부면으로 흐르는 공기에 의하여 양력이 발생하여 차체가 뜨게 되는 문제점이 있었다.However, in the conventional front bumper, since the front bumper face is not in close contact with the vehicle body, outside air flows into the space between the front bumper and the body of the vehicle during driving. There is a problem in that the running performance is reduced, and lift is generated due to air flowing to the lower surface of the vehicle body.

본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로, 프론트범퍼페이시어의 하단에 돌출부를 형성하여 차량주행시 프론트범퍼의 전면으로 유입되는 공기의 일부를 차체측면을 따라 흐르게 함으로써 차체하부로 유입되는 공기의 양을 감소시키고, 또한 상기 돌출부에서 절곡되어 플랜지부를 형성하여 상기 플랜지부에 의해 프론트범퍼페이시어와 차량의 보디가 밀착될 수 있게 함으로써 차체와 프론트범퍼 사이의 공간에서 와류가 생성되는 것을 방지하도록 함에 그 목적이 있다.The present invention was devised to solve the above problems, by forming a protruding portion at the bottom of the front bumper facer to flow into the lower part of the vehicle body by flowing a part of the air flowing into the front of the front bumper when driving the vehicle along the side of the vehicle body. To reduce the amount of air, and to form a flange portion by bending at the protrusion to allow the front bumper facer and the body of the vehicle to come into close contact with each other to generate vortex in the space between the vehicle body and the front bumper. The purpose is to prevent it.

상기와 같은 목적을 달성하기 위한 본 고안은, 차량의 전면에 장착되는 프론트범퍼에 있어서, 상기 프론트범퍼의 외곽을 이루는 프론트범퍼페이시어의 하단 전면으로 돌출부가 형성되고, 상기 돌출부에서 절곡되어 플랜지부가 형성된 것을 특징으로 한다.The present invention for achieving the above object, in the front bumper mounted on the front of the vehicle, a protrusion is formed on the front surface of the lower end of the front bumper face forming the outer of the front bumper, bent from the protrusion flange portion Characterized in that formed.

차량진행시 프론트범퍼의 전면으로 유입되는 차량전방의 공기는 본 고안에 의해 프론트범퍼의 하단에 돌출부가 형성됨에 따라 프론트범퍼 하측으로의 흐름이 방해받게 되며 이에 따라 프론트범퍼의 측면으로 흐르게 된다. 또한, 돌출부에서 절곡 형성된 플랜지부가 차량보디에 밀착됨에 따라 차량보디와 프론트범퍼 사이의 공간으로 공기가 유입되는 것이 방지된다.The air in front of the vehicle flowing into the front of the front bumper during the vehicle progression is prevented from flowing to the lower side of the front bumper as the protrusion is formed at the bottom of the front bumper according to the present invention and thus flows to the side of the front bumper. In addition, as the flange portion bent from the protrusion is in close contact with the vehicle body, air is prevented from entering the space between the vehicle body and the front bumper.

이하, 본 고안의 실시예를 예시도면에 의거하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도2에 도시된 바와 같이, 차량의 프레임을 구성하는 프론트롱지튜디널부재(2)의 전면에는 범퍼스테이(3)가 취부되고 상기 범퍼스테이(3)에는 프론트범퍼(4)가 체결되어 있다. 상기 프론트범퍼(4)의 내부구조는 일반적인 범퍼의 구조와 동일한 것으로, 스틸 임팩트빔(5)과 플라스틱 허니컴에너지업쇼바(6)와 프론트범퍼페이시어(11)로 이루어져 있으며, 본 고안에서는 상기 프론트범퍼페이시어(11)의 하단 전면으로 돌출부(12)를 형성하고 상기 돌출부(12)에서 절곡되어 플랜지부(13)가 형성되어 있다. 이에 따라, 차량의 주행시 프론트범퍼(4)로 유입되는 차량전방의 공기는 프론트범퍼(4) 하단의 돌출부(12)에 의해 차량하부로의 흐름이 방해받게 되므로 프론트범퍼(4)측면을 따라 차체의 측면으로 흐르게 된다. 이와 같이, 차체의 하부로 유입되는 공기의 흐름량이 감소함에 비례하여 주행시 발생되는 양력의 크기 또한 감소하게 된다.As shown in FIG. 2, a bumper stay 3 is mounted on a front surface of the front long terminal member 2 constituting the vehicle frame, and a front bumper 4 is fastened to the bumper stay 3. The internal structure of the front bumper (4) is the same as the structure of a general bumper, consisting of a steel impact beam (5), a plastic honeycomb energy upshoe (6) and a front bumper facer (11), in the present invention the front A protrusion 12 is formed on the lower front surface of the bumper face 11 and is bent from the protrusion 12 to form a flange 13. Accordingly, the air in front of the vehicle flowing into the front bumper 4 when the vehicle is running is disturbed by the protrusion 12 at the bottom of the front bumper 4 so that the flow to the lower part of the vehicle is prevented along the front bumper 4 side. Will flow to the side. As such, the amount of lift generated during driving is also reduced in proportion to the decrease in the amount of air flowing into the lower portion of the vehicle body.

또한, 상기 프론트범퍼페이시어(11)는 하단의 돌출부(12)에서 절곡되어 플랜지부(13)가 형성되어 있음에 따라, 상기 플랜지부(13)에 의해 프론트범퍼(4)의 하부가 차체에 밀착 되므로 차량주행시 프론트범퍼(4) 하측으로 유입되는 차량전방의 공기가 차체와 프론트범퍼(4) 사이의 공간에서 와류를 생성하는 것을 방지하게 된다.In addition, since the front bumper facer 11 is bent from the protrusion 12 at the lower end thereof so that the flange portion 13 is formed, the lower portion of the front bumper 4 is connected to the vehicle body by the flange portion 13. Since the vehicle is in close contact with the front bumper 4 when the vehicle is driven, the air in front of the vehicle is prevented from generating a vortex in the space between the vehicle body and the front bumper 4.

위와 같이 차량전면에 장착되는 본 고안에 의한 프론트범퍼는 프론트범퍼페이시어의 하단 전면으로 돌출부를 형성하고 상기 돌출부에서 절곡시켜 플랜지부를 형성함에 따라서, 차량주행시 프론트범퍼로 유입되는 차량전방의 공기가 상기 돌출부에 의해 차체 하부로의 흐름이 방해받게 되므로 차체하부로 유입되는 공기의 양이 감소하여 이로 인한 차체 부양력의 감소효과를 기대할 수 있으며, 플랜지가 차량보디에 밀착되므로 차량보디와 프론트범퍼 사이의 공간에서 생성되는 와류로 인한 소음 및 공기의 저항을 제거하여 정숙성 및 주행성능의 개선을 실현할 수 있는 효과를 제공한다.The front bumper according to the present invention, which is mounted on the front of the vehicle, forms a protrusion on the bottom front surface of the front bumper facer and forms a flange by bending at the protrusion, so that air from the front of the vehicle flowing into the front bumper when the vehicle is driven. Since the flow to the lower part of the body is hindered by the protrusion, the amount of air flowing into the lower part of the body is reduced, and thus, a reduction effect of the body buoyancy can be expected, and the flange is in close contact with the body of the vehicle, so that between the body and the front bumper The noise and air resistance caused by the vortex generated in the space are removed to provide the effect of improving the quietness and driving performance.
