본 발명은 범퍼 에너지 업서버 폼 개선 구조에 관한 것으로서, 더욱 상세하게는 범퍼 페이시아(Bumper Facia)와 범퍼 백빔(Back Beam)사이에 설치되어 차량의 충돌 시 보행자를 보호하고, 타 물체와 저속 충돌시 범퍼 백빔 보호, 범퍼 페이시아 형태를 유지시켜 주는 범퍼 에너지 업서버 폼 개선 구조에 관한 것이다.The present invention relates to a bumper energy upserver form improvement structure, and more particularly, it is installed between bumper facia and bumper back beam to protect pedestrians when a vehicle collides, and to collide with other objects at low speed. Bumper back-up protection, bumper energy upserver form improvement structure to maintain bumper fascia shape.

일반적으로, 자동차의 전·후방에는 외부에서 가해지는 충격을 완충시켜 차체 및 자동차 탑승자를 보호할 수 있도록 된 범퍼가 구비되고, 이 범퍼의 범퍼페이스 내측에는 외부충격 등을 완충시킬 수 있도록 된 에너지 업서버 폼 등 완충재가 충진되는 것이 보편화 되어 있다.In general, the front and rear of the car is provided with a bumper to cushion the impact from the outside to protect the vehicle body and the occupant of the vehicle, the energy up to buffer the external shock, etc. inside the bumper face of the bumper Filling of cushioning materials such as server foam is common.

따라서, 자동차의 전방 및 후방에서 외부충격이 가해질시, 상기 충격이 범퍼페이스의 형상이나 재질 등에 따라 1차 완화되고, 이 범퍼 페이스에서 미처 완충되지 못한 외부충격이 에너지 업서버 폼 등 완충재에 의해 완충 되도록 된다.Therefore, when an external shock is applied at the front and rear of the vehicle, the shock is primarily mitigated according to the shape and material of the bumper face, and the external shock that is not buffered at the bumper face is buffered by a buffer such as an energy upserver foam. To be possible.

도 1에서 보듯이, 자동차의 전방 프레임을 이루는 캐리어(10)와, 이 캐리어(10) 전방부분에 체결되는 백빔(20)과, 이 백빔(20) 상에 결합되는 에너지 업서버 폼(30)과 그 하다부에 마련되는 로어 스티프너(40)와, 이러한 구성으로 이루어진 범퍼 외관을 감싸는 범퍼커버(50)로 구성된다.As shown in FIG. 1, a carrier 10 constituting a front frame of an automobile, a back beam 20 fastened to a front portion of the carrier 10, and an energy upserver form 30 coupled to the back beam 20. And a lower stiffener 40 provided at the lower portion thereof, and a bumper cover 50 surrounding the bumper exterior having the above configuration.

이러한 구성으로, 자동차의 전방 범퍼에는 보행자 보호를 하기 위해서 로어 스티프너(lower stiffener)가 사용된다. 이는 차량이 보행자와 충돌할 때, 보행자의 무릎 아래의 다리를 범퍼가 치게 되는데, 이때 무릎의 인대 파열 및 무릎뼈의 파손을 방지하기 위하여 과도한 모멘트 발생이 일어나지 않도록 하기 위함이다. 이를 위하여 스티프너를 장착하여 하지에 두 개 이상의 스톱퍼가 작용되어 하지가 차량의 아래로 들어가지 않고 되돌아 나오도록 한다.In this configuration, a lower stiffener is used for the front bumper of the vehicle to provide pedestrian protection. This is because when the vehicle collides with the pedestrian, the bumper hits the leg under the pedestrian's knee, in order to prevent excessive moment from occurring in order to prevent tearing of the ligaments of the knee and damage to the knee bone. To this end, a stiffener is mounted so that two or more stoppers act on the lower extremity so that the lower extremity does not enter the underside of the vehicle.

그러나, 상기와 같은 종래의 구조는 다음과 같은 문제점을 가지고 있다.However, such a conventional structure has the following problems.

상기 스티프너는 보행자 보호를 위하여 아주 만족스러운 성능을 주지만, 상기 도 1에서 보여진 형상처럼 무게 및 장착 방법의 제한 등으로 판의 형태를 가지고 있다. 또한 주로 경량화를 위하여 플라스틱을 재질로 사용하고 있다. 상기 스티프너는 타 물체와 충돌시 충돌에너지를 흡수하는 능력이 부족하다 그 이유로는 판의 형상으로 인하여 충돌시 도 2와같이 벤딩이 일어나 휘어져 버리는 문제점이 있었다.The stiffener gives a very satisfactory performance for the protection of pedestrians, but has a form of a plate due to the limitation of weight and mounting method as shown in FIG. 1. In addition, plastic is mainly used as a material for light weight. The stiffener lacks the ability to absorb the collision energy when colliding with another object. For this reason, there is a problem that bending occurs due to the shape of the plate as shown in FIG. 2.

또한, 같은 역할을 하는 범퍼 에너지 업서버 폼과 로어 스티프너를 두 개로 별도 개발 장착함으로써 발생되는 개발비 증가와 중량 증대, 제작비 증가의 문제점을 가지고 있었다.In addition, the development cost and weight increase, the production cost increase caused by the separate development and installation of two bumper energy upserver foam and lower stiffener to play the same role.

In the server foam structure, the lower support portion 310 is provided to extend so as to act as a stiffener in the lower direction on both sides of the bumper energy upserver form 300.

상기 범퍼 에너지 업서버 폼(300)에는 강성과 강도를 향상시키기 위하여 스틸 또는 알루미늄으로 감싸진다.The bumper energy upserver foam 300 is wrapped in steel or aluminum to enhance rigidity and strength.

상기 하부 지지부(310) 각 하단부에 연장되어 내측 방향으로 만날 수 있도록 확장부(320)가 마련된다. 이 확장부(320)에는 이 확장부(320)의 강성을 증대시키기 위하여 강성 증대용 랩(500)이 외면에 감싸진다.Extension parts 320 are provided to extend in the lower ends of the lower support parts 310 so as to meet in the inward direction. In order to increase the rigidity of the expansion part 320, the expansion part 320 is wrapped in the stiffness increasing wrap 500 on the outer surface.

상기 확장부(320) 외면에 체결되어 충돌 에너지 흡수량 조절이 가능하도록 변화하는 단면을 가지고, 차체 프레임 상에 상기 범퍼 에너지 업서버 폼(300)이 고정될 수 있도록 마련된 로드(400)가 구성되고, 이 로드(400)에는 그 강성을 증대시키기 위하여 스틸 또는 알루미늄이 외면에 감싸진다.The rod 400 is fastened to an outer surface of the expansion unit 320 and has a cross section that changes to adjust the amount of collision energy absorption, and a rod 400 provided to fix the bumper energy upserver form 300 on a vehicle body frame. The rod 400 is wrapped with steel or aluminum to the outside to increase its rigidity.

상기 로드(400)는 차량이 고속으로 주행중 일체형 범퍼 업서버 폼(300)이 차량에 단단하게 고정되어 있도록 하기 위하여 범퍼 업서버 폼(300) 아래에 감싸진 철판과 서브 프레임을 상기 로드(400) 브라켓을 이용하여 고정되도록 한 것이다.The rod 400 may include an iron plate and a subframe wrapped under the bumper upserver form 300 so that the integrated bumper upserver form 300 is firmly fixed to the vehicle while the vehicle is traveling at high speed.

도 5는 본 발명에 따른 범퍼 에너지 업서버 폼 개선 구조의 보행자 충돌시 충돌 위치를 도시한 도면이고, 도 6은 본 발명에 따른 범퍼 에너지 업서버 폼 개선 구조의 차량 감속도 개선효과를 도시한 도면이다.5 is a view showing a collision position during the pedestrian collision of the bumper energy upserver form improvement structure according to the present invention, Figure 6 is a view showing the vehicle deceleration improvement effect of the bumper energy upserver form improvement structure according to the present invention. to be.

차량이 보행자와 충돌이 일어나게 되면 도 5에서와 같이, A와 B에서 동시에 보행자의 하지와 접촉하게 된다. 이렇게 동시에 접촉함으로써 하지를 밀어내어 무릎 부위에 과도한 벤딩 모멘트가 걸리는 것을 방지하게 된다. 즉, 기존의 기술에서 로어 스티프너(40)의 역할을 대체하는 역할을 한다.When the vehicle collides with the pedestrian, as shown in FIG. 5, A and B simultaneously come into contact with the lower surface of the pedestrian. This simultaneous contact pushes the lower extremities and prevents excessive bending moments from being applied to the knees. That is, it serves to replace the role of the lower stiffener 40 in the existing technology.

또한, 범퍼 에너지 업서버 폼(300) 하부의 확장부(320) 부분을 서브 프레임과 로드를 이용하여 연결함으로써, 충격량이 큰 고속 정면 충돌의 경우, 범퍼 에너지 업서버에서 일정량의 충격 에너지를 흡수함으로써, 타 차량 등과 충돌시에 도 6에서와 같이 운전자에게 가해지는 차량의 감가속도는 충돌 초기에 상승되고 충돌 후기에는 감소되는 현상이 나타난다. 이것은 승객 구속장치의 조기 구속과 승객에게 가해지는 최대 감가속도를 적게 함으로써 승객의 상해 치를 줄일 수 있다.In addition, by connecting a portion of the extension 320 under the bumper energy upserver form 300 by using a subframe and a rod, in the case of a high-speed frontal impact with a large impact amount, a predetermined amount of impact energy is absorbed by the bumper energy upserver For example, as shown in FIG. 6, when the vehicle collides with another vehicle, the deceleration of the vehicle that is applied to the driver increases in the early stage of the collision and decreases in the late stage of the collision. This can reduce passenger injuries by premature restraint of the passenger restraint and by reducing the maximum deceleration exerted on the passenger.
