Description
본 고안은 자동차의 전, 후면 충돌시 완충 작용을 하도록 자동차 범퍼의 내부에 설치되는 완충 폼에 관한 것이다.The present invention relates to a cushioning foam that is installed inside the bumper of the vehicle so as to cushion the front and rear of the vehicle.
통상적으로, 자동차의 범퍼는 차량의 주행시 자동차 또는 외부 물체와의 충돌시 그 충격을 어느 정도 흡수하여 차체에 가해지는 충력량을 감소시켜, 차량 및 운전자 또는 차량 탑승자가 손상 또는 부상을 방지하고자 차량의 전방 및 후방에 설치된다.Typically, a bumper of a vehicle absorbs the impact to some extent when the vehicle collides with a vehicle or an external object to reduce the amount of force applied to the vehicle body, thereby preventing the vehicle and the driver or the occupant of the vehicle from being damaged or injured. It is installed at the front and rear.
이러한 자동차의 범퍼는 차량의 충돌시 상대방 차량과 직접 접촉하도록 외부에 노출되는 범퍼 페이스(face), 범퍼 페이스를 보강함과 아울러 범퍼 페이스를 차체에 취부하도록 된 보강재 및 차량 충돌시 충격을 완충하도록 범퍼 페이스와 보강재 사이에 설치되는 완충 폼으로 이루어진다.The bumper of such a vehicle reinforces the bumper face exposed to the outside to directly contact the other vehicle when the vehicle collides, the bumper face, and the reinforcement that attaches the bumper face to the vehicle body and cushions the impact during the vehicle collision. It consists of a cushioning foam installed between the face and the reinforcement.
이중에서 완충 폼은 주로 폴리프로필렌 재질을 발포시켜 이루어지는 발포물로서, 도 1A 및 도 1B에 도시된 바와 같은 형상을 가진다.In particular, the cushioning foam is a foam mainly formed by foaming a polypropylene material, and has a shape as shown in FIGS. 1A and 1B.
그러나, 상기한 바와 같은 범퍼에 있어서 종래의 완충 폼은 단일 재질의 단순한 구조로 차량 충돌시 한 번에 충격을 흡수하도록 되어 있으므로 충격을 효과적으로 흡수할 수 없는 문제점이 있었다.However, in the bumper as described above, the conventional cushioning foam has a problem in that the shock absorber cannot be effectively absorbed because the shock absorber is designed to absorb a shock at the time of a vehicle collision.
따라서, 본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로, 자동차의 충돌시 그 충격을 효과적으로 흡수할 수 있는 구조를 가지는 자동차 범퍼의 완충 폼을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a shock absorbing foam for an automobile bumper having a structure that can effectively absorb the impact during a collision of the vehicle.
도 1A 는 일반적인 자동차 범퍼의 완충 폼을 도시한 사시도.1A is a perspective view of a cushioning foam of a typical automobile bumper;
도 1B 는 도 1A의 IB-IB선을 따라 취한 완충 폼의 단면도.1B is a cross-sectional view of the cushioning foam taken along line IB-IB in FIG. 1A.
도 2 는 도 1B에 대응되는 본 고안에 다른 완충 폼의 단면도.Figure 2 is a cross-sectional view of the buffer foam according to the present invention corresponding to Figure 1B.

1 : 발포물2 : 보강 플레이트1 foam 2 reinforcement plate
상기와 같은 목적을 달성하기 위한 본 고안은 자동차의 전, 후면 충돌시 완충 작용을 하도록 자동차 범퍼의 범퍼 페이스와 보강재 사이에 설치되는 완충 폼으로서, 충격에 대한 강성을 보강하기 위한 금속재 보강 플레이트가 내부 소정 위치에 수직하게 삽입되는 것을 특징으로 한다.The present invention for achieving the above object is a cushioning foam that is installed between the bumper face and the reinforcement of the bumper of the car so as to cushion the front and rear collision of the vehicle, the metal reinforcing plate for reinforcing the rigidity against impact It is characterized in that it is inserted perpendicular to a predetermined position.
[실시예]EXAMPLE
이하, 본 고안의 바람직한 일 실시예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in detail.
도 3에 본 고안에 따른 자동차 범퍼의 완충 폼이 도시되어 있다.3 shows a cushioning foam of an automobile bumper according to the present invention.
도시된 바와 같이, 본 고안에 따른 자동차 범퍼의 완충 폼은 폴리플로필렌 재질을 발포시켜 형성한 발포물(1)의 내부에 보강 플레이트(2)가 삽입, 설치됨으로써 이루어진다.As shown, the cushioning foam of the automobile bumper according to the present invention is made by inserting and installing the reinforcing plate (2) inside the foam (1) formed by foaming a polyflopropylene material.
상기 보강 플레이트(2)는 대략 0.8~1.2 사이의 두께를 가지는 금속 재질의 플레이트로서, 충격흡수성능이 향상될 수 있도록 완만하게 형성되는 요철부를 가진다. 또한 보강 플레이트(2)는 발포물(1)의 내부에 수직으로 삽입되며, 상기 발포물(1)의 전면으로부터 대략 30mm의 떨어진 위치에 삽입된다.The reinforcing plate 2 is a metal plate having a thickness of about 0.8 to 1.2, and has a concave-convex portion that is gently formed so that the shock absorbing performance can be improved. The reinforcing plate 2 is also inserted vertically inside the foam 1 and is inserted at a position approximately 30 mm away from the front of the foam 1.
이러한 구조를 가지는 본 고안에 따른 자동차 범퍼의 완충폼은 충돌시 범퍼 페이스로부터 발포물을 통하여 보강재로 전달되는 충격이 보강 패널에 의해 상당부분 흡수되므로 범퍼 완충 폼의 충격에너지 흡수 성능이 향상된다.The shock absorbing foam of the automobile bumper according to the present invention having such a structure is improved in the impact energy absorption performance of the bumper cushioning foam because the impact transmitted from the bumper face to the reinforcement through the foam is absorbed by the reinforcement panel.
상기된 바와 같은 본 고안은 발포물의 내부에 설치되는 보강 플레이트에 의해 완충 폼의 충격 에너지 흡수 성능이 향상되므로, 충돌시 그 충격을 효과적으로 흡수하여, 범퍼 및 차체를 보호할 수 있는 장점이 있다.The present invention as described above is improved by the impact energy absorption performance of the cushioning foam by the reinforcing plate installed inside the foam, there is an advantage that can effectively absorb the impact during a collision, to protect the bumper and the vehicle body.
