Description
본 발명은 자동차용 범퍼에 관한 것으로, 더욱 상세하게는 자동차와 보행자간의 충돌사고가 발생할 경우 보행자의 신체부위 손상을 최소화할 수 있도록 발명된 것이다.The present invention relates to a bumper for automobiles, and more particularly, to minimize damage to body parts of pedestrians when a collision accident between a vehicle and a pedestrian occurs.
일반적으로, 범퍼(Bumper)는 자동차의 앞 또는 뒤에 부착되어 충돌사고가 발생될 경우 자동차에 전달되는 충격력을 흡수하는 역활을 하게되는 충격 완화 장치로, 보행자 법규 규제치(가속도 규제, 굽힘각 규제, 전단변위 규제)에 만족하도록 설계되어진다.In general, a bumper is a shock mitigation device that is attached to the front or the rear of a vehicle to absorb the impact force transmitted to the vehicle in the event of a crash. Pedestrian regulations (acceleration regulation, bending angle regulation, shear) The displacement regulation).
즉, 플라스틱재 범퍼페이스와, 상기 범퍼페이스내에 충진된 완충재와, 상기 범퍼페이스의 후방에 설치된 스틸레일로 구성되어 있다.That is, it consists of a plastic material bumper face, the buffer material filled in the said bumper face, and the steel rail provided in the back of the said bumper face.
따라서, 상기 펌퍼페이스방향으로 충격이 가해지면 펌퍼페이스로 부터 완충재, 스틸레일로 순차적인 충돌 충격이 전달되면서 완충작용이 일어나게 되는데, 보행자와의 충돌일 경우에는 보행자의 허벅지와 정강이 즉, 다리부위와의 충돌이 발생하게 된다.Therefore, when an impact is applied in the direction of the pump face, a shock is generated while a sequential impact is transmitted from the pump face to the cushioning material and the steel rail. In the case of a collision with the pedestrian, the thigh and the shin of the pedestrian, Will cause a collision.
즉, 보행자와의 충돌사고가 발생되게 되면, 상기 범퍼페이스내에 충진되어 있는 완충재에 의해 보행자는 충돌의 충격으로 부터 보호받게 되는 것이다.That is, when a collision accident with the pedestrian occurs, the pedestrian is protected from the impact of the collision by the cushioning material filled in the bumper face.
상기와 같이 구성된 종래의 자동차용 범퍼는, 자동차와 보행자와의 충돌 사고가 발생할 경우 보행자의 신체부위중 특히 다리부위에 치명적인 상해가 발생할 수 있다.The conventional bumper for automobiles configured as described above may cause fatal injuries, especially in the leg part of the body part of the pedestrian when a collision accident between the car and the pedestrian occurs.
이는, 보행자 법규 중 굽힘각 규제에 따른 것으로, 자동차와 충돌이 발생할 경우 보행자의 다리부위 중 무릅을 기준으로 허벅지와 정강이의 굽힘각이 15°이상으로 꺽여지는데, 이는 범퍼페이스내에 충진되어 있는 완충재가 연질의 것으로 보행자의 정강이를 상부로 상승시키지 못하는 것에 의해 허벅지와 정강이의 굽힘각이30°이상으로 꺽이는 것에 의해 치명적인 상해가 발생할 수 있는 등의 문제점이 있었다.This is in accordance with the bending angle regulation of the pedestrian legislation.In the event of a collision with a car, the bending angle of the thigh and the shin is bent over 15 ° based on the knee of the leg of the pedestrian, which is the cushioning material filled in the bumper face. There is a problem that a fatal injury may occur by bending the angle of the thigh and the shin over 30 ° due to the inability to raise the shin of the pedestrian upward.
본 발명의 목적은, 범퍼페이스 내측에 완충재 및 굽힘방지수단을 설치하여 보행자와 자동차의 충돌이 발생할 경우 보행자의 정강이부위를 상부로 상승시켜 허벅지와 정강이의 굽힘각이 15°이내로 줄일 수 있는 것에 의해 손상부위를 최소화할 수 있는 자동차용 범퍼를 제공하는 데 있다.An object of the present invention is to install a cushioning material and a bend preventing means inside the bumper face by raising the shin portion of the pedestrian to the upper portion when the collision between the pedestrian and the car can be reduced by reducing the bending angle of the thigh and shin within 15 °. An object of the present invention is to provide a bumper for an automobile that can minimize damage.

상기 범퍼페이스의 내측으로 완충재의 하부에 설치된 굽힘방지수단으로 구성되어 달성된다.It is achieved by consisting of the bending preventing means installed in the lower portion of the cushioning material to the inside of the bumper face.
따라서, 자동차와 보행자간의 충돌이 발생할 경우 상기 완충재 하부에 설치되어 있는 굽힘방지수단이 보행자의 다리부위 중 정강이를 상부로 상승시켜, 허벅지와 정강이와의 굽힘각을 최소화시키므로써, 충돌에 의한 손상부위를 최소화시킬 수 있는 것이다.Therefore, in the event of a collision between a car and a pedestrian, the bend preventing means installed at the lower portion of the cushioning material raises the shank to the upper part of the leg part of the pedestrian, thereby minimizing the bending angle between the thigh and the shin, thereby causing damage to the site. This can be minimized.
이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명인 자동차용 범퍼를 사시도로 도시한 것으로, 자동차의 앞, 뒤쪽에 부착되는 범퍼페이스의 형상을 나타낸 것이다.1 is a perspective view of a bumper for a vehicle according to the present invention, and shows a shape of a bumper face attached to a front and a rear of a vehicle.
도 2는 제 1도의 A - A'선을 단면도로 도시한 것으로, 범퍼페이스(11)의 내측으로 충돌이 발생할 경우 자동차 및 보행자를 충격으로 부터 보호할 수 있는 완충재(10)가 설치되며, 상기 완충재(10)를 향해 충돌방향에 대하여 지지할 수 있도록 스틸레일(20)이 상기 완충재(10)의 후방에 설치된다.FIG. 2 is a cross-sectional view taken along line AA ′ of FIG. 1, and a shock absorbing material 10 may be installed to protect a vehicle and a pedestrian from impact when a collision occurs inside the bumper face 11. The steel rail 20 is installed at the rear of the shock absorber 10 so as to be supported in the collision direction toward the shock absorber 10.
상기 완충재(10)는 충돌이 발생할 경우 충격을 흡수할 수 있는 연질의 발포수지로 된 것을 사용하는 것이 좋다.The cushioning material 10 is preferably made of a soft foamed resin that can absorb the impact when a collision occurs.
그리고, 상기 범퍼페이스(11)의 내측에 설치된 완충재(10)의 하부에는 굽힘방지수단(30)이 설치되는데, 상기 굽힘방지수단(30)은 대략 20mm의 지름에 1t의 두께를 갖는 스틸 파이프(31)가 사용된다.In addition, a bending preventing means 30 is installed at a lower portion of the cushioning material 10 installed inside the bumper face 11, and the bending preventing means 30 is a steel pipe having a thickness of about 1 t and a diameter of about 20 mm. 31) is used.
이는, 보행자 법규(가속도 규제, 굽힘각 규제, 전단변위 규제)의 규제치를 만족할 수 있는 것으로, 자동차와 보행자간의 충돌이 발생할 경우, 보행자의 다리부위 손상여부는 무릅을 기준으로 허벅지와 정강이의 굽힘각에 의해 판단할 수 있는데, 보행자 법규 중 굽힘각 규제에 의하면 15°이상의 굽힘각이 발생할 경우 보행자는 치명적인 상해를 당할 수 있다.This can satisfy the regulations of pedestrian laws (acceleration regulation, bending angle regulation, shear displacement regulation) .In case of collision between car and pedestrian, if the leg part of pedestrian is damaged, bending angle of thigh and shin based on knee According to the bending angle regulation, the pedestrian may be fatally injured if a bending angle of more than 15 ° occurs.
즉, 상기 굽힘방지수단(30)인 스틸파이프(31)가 완충재(10)의 하부에 설치되게 되면, 자동차와 보행자간의 충돌시 발생되는 충격은 범퍼페이스(11)로 부터 완충재(10), 굽힘방지수단(30)인 스틸파이프(31)로 전달되며, 그 후방에 설치되어 충돌방향에 대하여 지지할 수 있는 스틸레일(20)로 순차적인 충격이 전달되면서 완충작용이 일어나게 된다.That is, when the steel pipe 31, which is the bending preventing means 30, is installed at the lower portion of the cushioning material 10, the impact generated during the collision between the vehicle and the pedestrian is the cushioning material 10 from the bumper face 11, bending It is transmitted to the steel pipe 31, which is a prevention means 30, and the shock absorbing action occurs while the sequential shock is transmitted to the steel rail 20 which is installed at the rear thereof and can support the collision direction.
이때, 보행자의 정강이를 굽힘방지수단(30)인 스틸파이프(31)가 상부로 상승시켜 허벅지와 정강이간의 굽힘각을 15°이내로 줄일 수 있는데, 이는, 정강이가 상부로 상승하게 되면 허벅지와의 굽힘각이 감소하게 된다.At this time, the steel pipe 31, which is the bending prevention means 30, is raised to the upper portion to reduce the bending angle between the thigh and the shank to within 15 °, which is caused by bending the thigh when the shank rises to the upper portion. The angle is reduced.
그러므로, 보행자 법규의 규제치를 만족하여 자동차와의 충돌에 의한 치명적인 손상으로 부터 보행자를 보호할 수 있는 것이다.Therefore, it is possible to protect the pedestrian from the fatal damage caused by the collision with the car by satisfying the regulation value of the pedestrian law.
상기와 같은 본 발명의 구성에 의하면, 보행자 법규의 규제치(15°)를 만족시킬 수 있는 굽힘방지수단인 스틸파이프를 범퍼페이스의 내측에 설치하므로써, 자동차와 보행자간의 충돌이 발생할 경우 보행자의 정강이를 상기 굽힘방지수단이 상부로 상승시키는 것에 의해 규제치 이상으로 허벅지와 정강이가 굽히는 것에 의해 발생할 수 있는 치명적인 손상으로 부터 보호자를 보호할 수 있는 등의 매우 유용한 발명인 것이다.According to the configuration of the present invention as described above, by installing a steel pipe, which is a bending prevention means that can satisfy the regulation value (15 °) of the pedestrian legislation inside the bumper face, when the collision between the car and the pedestrian occurs, the shin of the pedestrian is It is a very useful invention to protect the protector from the fatal damage that may occur by bending the thigh and the shank above the regulation value by raising the bending preventing means upward.
