본 발명은 차량에 설치되는 범퍼의 조립구조에 관한 것이다.The present invention relates to an assembly structure of a bumper installed in a vehicle.

일반적으로, 자동차는 동력을 발생시키는 엔진을 비롯하여 자동차의 외형을 구성하는 차체와 상기 차체에 장착되어 엔진에서 발생되는 동력을 이용하여 주행 및 정지를 가능하게 하는 샤시 등으로 이루어지며, 상기 차체는 다수의 패널이 용접이나 볼트 등의 결합을 통해 차량 전체의 외형을 이루고 있다.In general, an automobile includes an engine that generates power, a chassis that forms the exterior of the vehicle, and a chassis that is mounted on the vehicle to enable driving and stopping by using the power generated by the engine. The panel is forming the overall appearance of the vehicle by welding or bolting.

상기 차체에는 엔진과 변속기를 비롯하여 차량 운행에 필요한 각종 구성부품이 장착되어 있으며 사고로 인한 충돌 및 전복시에는 외부충격으로부터 차량내의 탑승자를 보호할 수 있을 정도의 충분한 강성을 구비해야 하며, 이와 함께 충격을 단계적으로 흡수하여 승객에게 전달되는 힘을 최소화함으로써 상해 정도를 줄일 수 있도록 구성되어 있다.The vehicle body is equipped with various components necessary for driving the vehicle, including the engine and the transmission, and should have sufficient rigidity to protect the occupants in the vehicle from external shocks in case of collision and overturning due to an accident. It is designed to reduce the degree of injury by minimizing the force transmitted to the passengers by absorbing step by step.

특히, 차량의 전방과 후방에 장착되는 프런트 범퍼와 리어 범퍼는 차량의 전방충돌 및 후방충돌 사고시에 발생되는 충격을 흡수하여 차체로 전달되는 충격이 최소화되도록 하여 탑승객을 보호함과 동시에 엔진을 비롯한 차량 각부의 차체를 보호하는 역활을 한다.In particular, the front bumper and the rear bumper mounted on the front and rear of the vehicle absorb shocks generated during the front collision and the rear collision accident of the vehicle to minimize the shock transmitted to the vehicle body to protect the passengers and at the same time the vehicle including the engine It serves to protect the body of each part.

상기 프런트 범퍼의 경우에는 통상적으로 차량대 차량의 충돌시에 자기차량을 보호하기 위해 범퍼의 외피를 이루는 범퍼커버와, 상기 범퍼커버의 형상유지와 충돌시에 충격을 완화하고 형상복원 기능을 갖는 에너지압소바, 및 상기 에너지압소바와 접촉되며 충돌시의 에너지를 탄성변형 또는 소성변형을 통하여 흡수하는 백빔을 포함하여 구성된다.In the case of the front bumper, a bumper cover which forms a bumper envelope to protect the own vehicle in the event of a collision between a vehicle and a vehicle, and an energy having a shape restoring function while alleviating an impact during a shape maintenance and collision of the bumper cover. And a back beam which is in contact with the energy absorber and absorbs the energy during the collision through elastic deformation or plastic deformation.

도 1은 종래의 범퍼 조립구조를 도시한 사시도로써, 범퍼커버(2)의 내측면에 형성된 마운틴 플랜지(3)에 에너지 압소바(4)가 삽입되어 클립(5)에 의해 고정되고, 상기 에너지 압소바(4)의 하부에 범퍼그릴(6)이 설치되는 구조로 조립되었다.1 is a perspective view illustrating a conventional bumper assembly structure, in which an energy absorber 4 is inserted into a mountain flange 3 formed on an inner surface of a bumper cover 2 to be fixed by a clip 5, and the energy absorber Assembled in the structure in which the bumper grill 6 is installed in the lower part of (4).

상기와 같이 조립된 종래의 범퍼(1)는 차체에 결합되는 범퍼커버(2)의 내측면 좌,우 상하에 마운틴 플랜지(3)가 구비되어 상기 마운틴 플랜지(3)에 에너지 압소바(4)를 삽입하고 클립(5)을 이용하여 고정한다.The conventional bumper 1 assembled as described above is provided with a mountain flange 3 on the upper and lower left and right sides of the inner surface of the bumper cover 2 which is coupled to the vehicle body, thereby providing energy absorbers 4 to the mountain flange 3. Insert and fix with the clip (5).

도 2a는 도 1에 도시된 a-a선 단면도로써, 에너지 압소바(4)는 범퍼커버(2)의 후면에 설치되는데 상기 범퍼커버(2)에 구비된 마운틴 플랜지(3)에 좌,우 상하로 총 4곳에 삽입되어 장착된다. 상기 범퍼커버(2)는 내측면에 성형된 마운틴 플랜지(3)가 범퍼커버(2)의 굴곡 부위에 성형된 상단보다 상대적으로 평평한 하단에 성형된 곳에 범퍼커버(2)의 외측에 싱크마크(Sink Mark) 현상이 발생한다.FIG. 2A is a cross-sectional view taken along the line aa of FIG. 1, and the energy absorber 4 is installed at the rear side of the bumper cover 2, and the left and right upper and lower sides are mounted on the mountain flange 3 provided in the bumper cover 2. It is inserted and mounted in four places. The bumper cover 2 has a sink mark on the outside of the bumper cover 2 where the mountain flange 3 formed on the inner side is formed at a lower end relatively flat than the upper end formed on the bent portion of the bumper cover 2. Sink Mark phenomenon occurs.

상기 포밍부(22)는 상기 에너지 압소바(20)의 후방을 향해 요입 형성되며, 상기 에너지 압소바(20)의 하부에 위치하고 포밍부(22)에 상단부가 설치되는 장착부(32)가 형성된 범퍼그릴(30)을 포함하여 구성된다.The forming unit 22 is recessed toward the rear of the energy absorber 20, and a bumper grill having a mounting portion 32 formed under the energy absorber 20 and having an upper end installed in the forming unit 22 ( 30).

상기와 같이 구성되는 차량의 범퍼 조립구조에 대해 도면을 참조하여 조립되는 과정을 상세히 설명한다.A process of assembling the bumper assembly structure of the vehicle configured as described above with reference to the drawings will be described in detail.

첨부된 도 3 내지 도 4를 참조하면, 작업자는 범퍼커버(10)의 내측에 형성된 마운틴 플랜지(12)에 에너지 압소바(20)를 삽입하여 클립(5)을 이용하여 고정한다. 3 to 4, the operator inserts the energy absorber 20 into the mountain flange 12 formed inside the bumper cover 10 and fixes the clip by using the clip 5.

상기와 같이 체결된 상태에서 에너지 압소바(20)의 내측 하부면상에 형성된 포밍부(22)에 범퍼그릴(30)의 장착부(32)를 면접촉시킨다.In the fastened state as described above, the mounting portion 32 of the bumper grill 30 is brought into surface contact with the forming portion 22 formed on the inner lower surface of the energy absorber 20.

상기 범퍼그릴(30)의 장착부(32)는 포밍부(22)에 설치되어 상기 범퍼그릴(30)의 플랜지력을 증가시켜 보다 더 견고히 고정된다.The mounting portion 32 of the bumper grill 30 is installed in the forming portion 22 to increase the flange force of the bumper grill 30 is more firmly fixed.

도 5는 도 3의 A-A선 단면도로써, 에너지 압소바(20)의 상단은 범퍼커버(10)에 형성된 마운틴 플랜지(12)에 의해 고정되고, 하단은 포밍부(22)에 면접촉되는 범퍼그릴(30)의 장착부(32)에 의해 지지 고정되어 범퍼커버(10)상에 고정된다.FIG. 5 is a cross-sectional view taken along line AA of FIG. 3, and an upper end of the energy absorber 20 is fixed by a mountain flange 12 formed on the bumper cover 10, and a lower end thereof is a bumper grill which is in surface contact with the forming unit 22. It is supported and fixed by the mounting portion 32 of the 30 is fixed on the bumper cover (10).

상기와 같은 상태로 조립하게되면 범퍼커버(10)와 에너지 압소바(20) 및 범퍼그릴(30)이 상호간에 지지됨과 동시에 견고히 체결되어 구조적으로 안정되게 조립된다.When assembled in the above state, the bumper cover 10 and the energy absorber 20 and the bumper grill 30 are mutually supported and firmly fastened to be structurally stable assembled.

한편, 본 발명은 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다. On the other hand, the present invention can be variously modified by those skilled in the art without departing from the gist of the invention.

이상에서 설명한 바와 같이, 본 발명에 따른 차량의 범퍼 조립구조는 범퍼커 버에 에너지 압소바를 조립하기 위해 마운틴 플래지와 클립의 갯수가 감소되어 원가 절감 및 직업성이 향상되는 효과가 있다.As described above, the bumper assembly structure of the vehicle according to the present invention has the effect of reducing the number of mountain flanges and clips in order to assemble the energy absorber to the bumper cover has the effect of reducing cost and improved professionalism.

또한, 상기 범퍼커버 하단의 마운틴 플랜지가 삭제되어 범퍼커버 외측에 싱크마크 현상이 발생하지 않으며, 상기 에너지 압소바의 하단에 포밍부를 형성하여 상기 포밍부에 설치되는 범퍼그릴과 에너지 압소바와의 지지력이 증대되어 보다 더 견고히 체결할 수 있는 효과가 있다.In addition, the mountain flange at the bottom of the bumper cover is deleted, so that no sink mark occurs on the outside of the bumper cover, and a forming portion is formed at the bottom of the energy absorber so that the bearing force between the bumper grill and the energy absorber installed at the forming portion is increased. There is an effect that can be tightened more firmly.
