Description

자동차용 범퍼의 충격흡수구조Shock Absorption Structure of Automobile Bumper

본 고안은 자동차용 범퍼의 충격흡수구조에 관한 것으로, 차체 진행방향과 충격에너지의 전달방향이 소정각도를 이루도록 되어 상기 충격에너지의 전파가 차체로 직접 전해지는 것이 방지됨에 따라 완충효율을 향상시킬 수 있도록 된 자동차용 범퍼의 충격흡수구조에 관한 것이다.The present invention relates to a shock absorbing structure of a bumper for automobiles, the vehicle body direction and the direction of the transmission of impact energy to achieve a predetermined angle to prevent the transmission of the impact energy directly to the vehicle body can improve the buffering efficiency The present invention relates to a shock absorbing structure of an automobile bumper.

일반적으로, 자동차의 전·후방에는 외부 이물질이나 타 차체 등과의 충돌에 따른 충격을 감소시켜 차체 및 자동차탑승자를 보호할 수 있도록 된 범퍼가 구비되는 바, 이 범퍼는 종래에 도 2에 도시된 바와 같이, 차체 전방의 슈라우드판넬(1) 전면에 범퍼(2) 전체를 지지할 수 있도록 대략 박스형상을 이룬 리인포스먼트(3)가 볼트 등을 매개로 체결되고, 이 리인포스먼트(3)의 전면에 일측면이 개구된 박스형상을 이루면서 차체 외형에 따라 다수부에서 절곡·성형된 범퍼페이스(5)가 취부되고, 이 범퍼페이스(5) 내에 충격을 완화시킬 수 있는 수지 등의 재질로 이루어진 에너지옵서버폼(4)이 충진된 구조로 되어 있다.In general, the front and rear of the car is provided with a bumper that can reduce the impact caused by collisions with foreign objects or other bodies to protect the vehicle body and the occupant, which is a conventional bumper as shown in FIG. Similarly, a substantially box-shaped reinforcement 3 is fastened via a bolt or the like so that the entire bumper 2 can be supported on the front shroud panel 1 in front of the vehicle body, and the reinforcement 3 A bumper face 5 bent and molded at a plurality of parts is mounted in a box shape with one side opening at the front side, and the bumper face 5 is made of a material such as resin that can alleviate impact. The energy observer form 4 is filled.

따라서, 상기 범퍼(2)의 외측에서 외부충격이 가해질시 범퍼페이스(5)의 형상 등에 의해 상기 외부충격이 1차 완화되고, 이 범퍼페이스(5)에서 미처 완화되지 못한 외부충격이 상기 범퍼페이스(5)와 밀착·취부된 에너지옵서버폼(4)에 의해 2차로 완충되며, 상기 범퍼페이스(5)와 에너지옵서버폼(4)은 리인포스먼트(3)에 의해 지지되도록 한다.Therefore, when the external shock is applied from the outside of the bumper 2, the external shock is primarily mitigated by the shape of the bumper face 5 or the like, and the external shock that is not alleviated by the bumper face 5 is the bumper face. Secondary buffering is performed by the energy observer form 4 in close contact with (5), and the bumper face 5 and the energy observer form 4 are supported by the reinforcement 3.

그러나 상기와 같이 범퍼페이스(5)와 에너지옵서버폼(4) 등이 다층형상을 이루면서 겹쳐 형성됨에 따라, 자동차의 정면충돌 등, 차체와 수평되는 방향에서 범퍼(2) 전면으로 외부 충격이 가해질시, 이 외부충격이 범퍼페이스(5)의 전면에 걸쳐 전달되고, 이 범퍼페이스(5)에 전해진 외부충격이 에너지옵서버폼(4)의 전면에 전해져 에너지옵서버폼(4) 자체의 충격흡수력에 따라 외부충격이 완화되거나 상기 에너지옵서버폼(4)이 압착되는 등 변형되면서 상기 외부충격이 완충되되, 이때 상기 에너지옵서버폼(4)이나 범퍼페이스(5)의 전면에 가해지는 외부충격이 범퍼(2)가 취부되도록 된 차체 리인포스먼트(3) 등에 의해 지지되도록 됨에 따라, 상기 외부충격에너지가 차체에 전해져 차체 및 차량탑승자에게 전해져 안정성이 저하되는 문제가 있었다.However, as the bumper face 5 and the energy observer foam 4 are formed in a multi-layered form as described above, when an external shock is applied to the front of the bumper 2 in a direction parallel to the vehicle body, such as a frontal collision of an automobile. The external shock is transmitted over the front surface of the bumper face 5, and the external shock transmitted to the bumper face 5 is transmitted to the front face of the energy observer form 4, and according to the shock absorbing force of the energy observer form 4 itself. The external shock is alleviated or the external shock is buffered as the energy observer foam 4 is deformed, and the like, wherein the external shock applied to the front surface of the energy observer form 4 or the bumper face 5 is bumper 2. ) Is supported by the vehicle body reinforcement (3), etc. to be mounted, there is a problem that the external impact energy is transmitted to the vehicle body and transmitted to the vehicle body and the vehicle occupant to reduce the stability.

이에 본 고안은 상기와 같은 제반 문제점을 해소하기 위해 안출된 것으로서, 외부에서 차체로 가해지는 충격방향이 범퍼 자체 형상에 의해 분산 및 방향전환되도록 되어 상기 외부충격이 충분히 완충되도록 됨은 물론, 차체에 직접 전해지는 것이 방지되어 완충효율을 향상시킬 수 있도록 된 자동차용 범퍼의 충격흡수구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, the impact direction applied to the vehicle body from the outside is dispersed and diverted by the bumper itself shape, so that the external shock is sufficiently buffered, as well as directly to the vehicle body It is an object of the present invention to provide a shock absorbing structure of a bumper for a vehicle that is prevented from being transmitted to improve a buffering efficiency.

도 2는 종래구조로서 도 1에 대응되는 구성도이다.2 is a configuration diagram corresponding to FIG. 1 as a conventional structure.

상기와 같은 목적을 달성하기 위한 본 고안은, 범퍼페이스의 전면에 대략 삼각형 단면을 이루도록 된 돌출부가 일체 형성되고, 이 범퍼페이스의 돌출부내에 에너지옵서버폼의 확장부가 충진된 구조로 되어 있다.In order to achieve the above object, the present invention has a structure in which a protrusion having a substantially triangular cross section is integrally formed on the front surface of the bumper face, and an extension of the energy observer form is filled in the protrusion of the bumper face.

상기와 같이 구성된 본 고안은, 자동차의 정면충돌 등 범퍼 전면에 외부충격이 가해질시, 상기 범퍼의 범퍼페이스 전면에 돌출된 돌출부에 전해지는 외부충격이 돌출부 선단에서 상·하 방향으로 분산되고, 상기 돌출부에 전해지는 외부충격이 돌출부 내측에 충진된 에너지 옵서버폼의 확장부에 의해 지지·완충된다.According to the present invention configured as described above, when an external shock is applied to the front of the bumper, such as a front collision of the vehicle, the external shock transmitted to the protrusion projected on the front of the bumper face of the bumper is dispersed in the vertical direction at the tip of the protrusion, External shocks transmitted to the protrusions are supported and buffered by the extension of the energy observer foam filled inside the protrusions.

이하, 첨부된 예시도면을 참조하여 본 고안에 따른 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 고안에 따른 범퍼를 도시한 것으로, 종래구조를 도시한 도 2와 동일한 부위에는 동일한 참조부호를 표기하면서 그에 대한 상세한 설명을 생략하기로 한다.Figure 1 shows a bumper according to the present invention, while the same reference numerals are denoted in the same parts as in Figure 2 showing a conventional structure and a detailed description thereof will be omitted.

본 고안은, 범퍼페이스(5)의 전면에 대략 상·하 대칭되는 삼각형 형상의 단면을 이루면서 상기 범퍼페이스(5)의 횡방향 폭과 동일한 폭을 이루고 외측으로 돌출된 돌출부(5a)가 일체 형성되고, 이 돌출부(5a)의 내측에 상기 범퍼페이스(5)에 내설되는 에너지옵서버폼(4)의 확장부(4a)가 밀착·취부된다.The present invention forms a cross section of a triangular shape that is substantially up-down symmetrical to the front surface of the bumper face 5 while forming the same width as the transverse width of the bumper face 5 and protruding outwards 5a integrally formed. Then, the extension portion 4a of the energy observer foam 4 embedded in the bumper face 5 is in close contact with and attached to the inner side of the protruding portion 5a.

따라서, 범퍼(2) 전면에 외부충격이 가해질시, 상기 외부충격이 돌출부(5a)에 의해 상·하 방향으로 분산되고, 이 돌출부(5a)에 가해지는 외부충격은 에너지옵서버폼(4)의 확장부(4a)에 의해 완충되며, 이 에너지옵서버폼(4) 및 범퍼페이스(5)가 슈라우드판넬(1) 등 차체에 체결된 리인포스먼트(3)에 의해 지지된다.Therefore, when an external shock is applied to the front surface of the bumper 2, the external shock is dispersed in the up and down directions by the protrusion 5a, and the external shock applied to the protrusion 5a is applied to the energy observer foam 4. The energy observer foam 4 and the bumper face 5 are supported by the reinforcement 3 fastened to the vehicle body such as the shroud panel 1 by being buffered by the expansion part 4a.

이상 설명한 것은 본 고안 자동차용 범퍼의 충격흡수구조를 실시하기 위한 하나의 실시예로서 제안된 것으로, 본 고안의 청구범위에서 청구하는 본 고안의 요지를 벗어남 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진자라면 누구라도 변경·실시가 가능할 것이다.What has been described above is proposed as one embodiment for implementing the shock absorbing structure of the bumper for automobiles of the present invention, without departing from the gist of the subject innovation claimed in the claims of the present invention, Anyone who owns it can change it.

이상 설명한 바와 같이 본 고안에 의하면, 범퍼(2)에 가해지는 외부충격에너지가 돌출부(5a) 및 확장부(4a)에 의해 분산되어 완충효율을 향상시킬 수 있으며, 상기 외부충격이 차체에 곧바로 가해지는 것이 방지되어 안정성을 향상시킬 수 있는 효과가 있다.As described above, according to the present invention, external impact energy applied to the bumper 2 may be dispersed by the protrusions 5a and 4a to improve the buffering efficiency, and the external shocks may be directly applied to the vehicle body. There is an effect that can prevent the loss to improve the stability.
