Description
본 고안은 차량의 전후방에 설치되어 차량 충돌시 충격을 흡수하는 범퍼(Bumper)에 관한 것이다.The present invention relates to a bumper (Bumper) is installed in the front and rear of the vehicle to absorb the shock during the vehicle crash.
차량의 전후방에 설치되는 범퍼는 차량의 충돌시 1차적으로 충격을 흡수하게 되는 부재이나 종래의 경우 단순히 발포우레탄수지로 프레임을 형성하여 설치하고 있어 차량 충돌시 충격에너지 흡수분산이 범퍼의 파손에만 의존하므로 충격 흡수효과가 낮아 엔진룸이 실내로 밀려들어와 탑승자의 상해치를 높이게 되는 문제점이 있었다.Bumpers installed in the front and rear of the vehicle are members that absorb shock primarily when the vehicle collides, but in the conventional case, they are simply formed by forming a frame with foamed urethane resin. Therefore, there is a problem that the impact absorption effect is low and the engine room is pushed into the room to increase the injury value of the occupant.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 차량 충돌시 충격에너지를 다단계로 흡수하여 승객을 보호하게 되는 범퍼를 제공하는데 있다.The present invention has been proposed in view of the above problems, and its object is to provide a bumper that protects passengers by absorbing impact energy in multiple stages during a vehicle crash.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1 은 본 고안에 의한 차량의 충격흡수용 범퍼를 나타내는 단면도로서 도면중 부호 1은 범퍼의 외부케이스이다.1 is a cross-sectional view showing a shock absorber bumper of the vehicle according to the present invention, the reference numeral 1 in the drawings is the outer case of the bumper.
외부케이스(1)는 발포우레탄 수지재나 또는 금속재로 형성되며 그 내부공간에는 고무튜브체(2)가 내장된다.The outer case 1 is formed of a foamed urethane resin material or a metal material, and a rubber tube body 2 is embedded in an inner space thereof.
고무튜브체(2)의 전면은 ㄹ자 형상의 요철부(3)로 형성되며 외부케이스(1)와의 사이에 형성되는 1차 공기층(4)에 공기가 충진되어 있다.The front surface of the rubber tube body (2) is formed of the r-shaped uneven portion (3) and the air is filled in the primary air layer (4) formed between the outer case (1).
그리고 상기 고무튜브체(2)의 내부공간 역시 공기가 충진되어 2차 공기층(5)을 형성하며 상기 고무튜브체(2)가 압축력을 받을 때 2차 공기층(5)내의 공기를 후방으로 배출토록 공기배출공(6)이 형성되어 있다.In addition, the inner space of the rubber tube body 2 is also filled with air to form a secondary air layer 5, and when the rubber tube body 2 receives a compressive force, the air in the secondary air layer 5 is discharged to the rear. An air discharge hole 6 is formed.
이와같은 본 고안은 차량이 충돌시 1차 공기층(4)에서 1차로 충격에너지를 흡수하게 되며 계속하여 고무튜브체(2)가 압착될 때 그 내부의 2차 공기층(5)에 의해 충격에너지를 흡수한 후 2차 공기층(5)내의 공기가 공기배출공(6)을 통해 후방으로 배출되면서 3차로 충격에너지를 분산하게 되는 것이다.In the present invention, when the vehicle collides, the impact energy is first absorbed by the primary air layer 4, and when the rubber tube body 2 is compressed, the impact energy is absorbed by the secondary air layer 5 therein. After absorption, the air in the secondary air layer 5 is discharged to the rear through the air discharge hole 6 to disperse the impact energy in the third.
이상과 같은 본 고안에 의한 범퍼에 의하면 범퍼케이스 내부에 1차 공기층 및 2차 공기층을 형성하는 고무튜브체를 내장하고 그의 후방에는 외부와 연통하는 공기배출공을 형성하는 것에 의해서 다단계로 충격에너지를 흡수하게 되므로써 충돌시 구조물의 실내유입을 방지하여 승객을 보호하게 되는 효과가 있다.According to the bumper according to the present invention as described above, the impact energy is multi-stage by forming a rubber tube body forming a primary air layer and a secondary air layer inside the bumper case and forming an air discharge hole communicating with the outside at the rear thereof. By absorbing, there is an effect of protecting the passengers by preventing the indoor flow of the structure in the event of a collision.
