Field of the Invention The present invention relates to a bumper structure for a vehicle, and more particularly, to a bumper for a pull-out vehicle that is configured to reduce a passenger's injury and damage to a vehicle by effectively absorbing impact energy by protruding a bumper face immediately before a vehicle collision or collision. will be.
주지된 바와 같이 차량용 범퍼는 차량 전후면에 장착되어 충돌 또는 추돌시 충격에너지로부터 차체와 탑승객을 보호하는 역할을 수행하는 바, 이러한 차량용 범퍼는 주로 차체에 고정되는 연결 브라켓트인 백범에 완충재와 범퍼 페이스가 연속 부착되는 구조로 되어 있는데, 종래 차량용 범퍼는 충돌 또는 추돌시 충격에너지를 효과적으로 흡수하지 못하여 탑승객과 차량 모두에게 심각한 상해와 훼손을 입히게 되는 안전성이 떨어지는 문제점이 있었다.As is well known, the vehicle bumper is mounted on the front and rear of the vehicle and serves to protect the body and passengers from impact energy in the event of a collision or collision.The vehicle bumper is mainly a connection bracket that is fixed to the vehicle body. Is a structure that is continuously attached, the conventional vehicle bumper has a problem in that the safety of the serious injury and damage to both the passengers and the vehicle can not be effectively absorbed due to the impact or collision impact energy.
그러나 종래에도 상기와 같은 문제점을 해결하기 위해 국내 실용신안공개공보 제 1998- 44297호로 제안된 유압식 범퍼장치는 도 2에 도시된 바와 같이 백범(101)에 유체가 담겨진 실린더(102)의 피스톤(110)과 범퍼 페이스(104)에 설치되는 완충재(105)가 연결되는 구조로 되어 있는데, 이러한 종래 유압식 범퍼구조는 충돌 또는 추돌시 충격에너지를 3단계로 완화하는 효과를 지니지만, 유체 역시 충돌시에는 강체와 유사하게 거동함에 따라 충격 흡수에너지를 보다 효과적으로 완화시킬 필요가 있었다.However, the conventional hydraulic bumper device proposed in the Korean Utility Model Publication No. 1998-44297 to solve the above problems, as shown in FIG. 2, the piston 110 of the cylinder 102 in which the fluid is contained in the back bump 101. ) And the cushioning material 105 installed on the bumper face 104 has a structure in which the conventional hydraulic bumper structure has the effect of mitigating impact energy in three stages during a collision or collision, As they behaved similarly to rigid bodies, it was necessary to more effectively mitigate the impact energy.
이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 차량 운행중 충돌 내지는 추돌 발생직전에 범퍼가 일정한 길이로 돌출 신장됨으로써 충돌 시간을 지연시키면서 인플레이트의 폭발가스가 충격에너지를 후차적으로 흡수할 수 있음에 따라 안전도를 향상시킨 인출식 자동차용 범퍼를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above-described conventional problems, the explosion gas of the in-flate after the impact time is delayed by delaying the collision time by the bumper protrudes to a certain length immediately before the collision or collision occurs during vehicle operation It is an object of the present invention to provide a bumper for a pull-out vehicle with improved safety as it can be absorbed.

상기와 같은 목적을 달성하기 위한 본 발명은 차체에 고정되는 백빔에 실린더 하우징이 연결되고, 이 실린더 하우징의 피스톤로드는 범퍼 페이스로 감싸진 완충재에 연결되어 이루어진 다단계 흡수식 자동차용 범퍼에 있어서, 상기 백빔의 내부에는 인플레이터가 내장되고 이 백빔의 내부와 실린더 하우징의 내부는 가스구멍을 매개로 연통되며 상기 실린더 하우징 내부에는 피스톤과 피스톤로드가 일체로 되어 내장되는 구조로 되어 있다.The present invention for achieving the above object is a cylinder housing is connected to the back beam fixed to the vehicle body, the piston rod of the cylinder housing is a multi-stage absorbing automotive bumper made of a bumper face wrapped in the bumper, the back beam An inflator is built in the interior of the back beam and the cylinder housing so as to communicate with each other through a gas hole, and the piston housing has a structure in which the piston and the piston rod are integrated.
이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 인출식 자동차용 범퍼에 전기적인 회로가 연결된 상태를 보여주는 개략 단면도이다.1 is a schematic cross-sectional view showing a state in which an electrical circuit is connected to the pull-out vehicle bumper according to the present invention.
본 발명은 차체에 고정되는 백빔(1)에 실린더 하우징(2)이 연결되고, 이 실린더 하우징(2)의 피스톤 로드(3)는 범퍼 페이스(4)로 감싸진 완충재(5)에 연결되어 이루어진 다단계 흡수식 자동차용 범퍼에 있어서, 상기 백빔(1)의 내부에는 제어부(6)와 케이블(7)을 매개로 전기적인 신호호 접단속되는 인플레이터(8)가 내장되고, 이 백빔(1)의 내부와 실린더 하우징(2)의 내부는 가스구멍(9)을 매개로 연통되며, 상기 실린더 하우징(2)의 내부에 장착되는 피스톤로드(3)는 피스톤(10)과 연결되어 이루어진 구조로 되어 있다.According to the present invention, a cylinder housing 2 is connected to a back beam 1 fixed to a vehicle body, and the piston rod 3 of the cylinder housing 2 is connected to a cushioning material 5 wrapped with a bumper face 4. In the multi-stage absorption type bumper for automobiles, an inflator 8 which is electrically connected to an electrical signal call through a control unit 6 and a cable 7 is built in the back beam 1. The inside of the cylinder housing 2 is communicated via the gas hole 9, and the piston rod 3 mounted inside the cylinder housing 2 is connected to the piston 10 has a structure.
또한 상기 인플레이터(8)를 작용시키는 제어부(6)는 초음파센서(11)와 연결되어 이 초음파센서(11)로부터 차량의 속도와 거리를 계측된 신호로 연산하는 제어부(6)에서 충돌 또는 추돌이 발생될 것으로 판단되면, 상기 제어부(6)는 인플레이터(8)를 폭발시키기 위해 폭발신호를 케이블(7)을 통하여 인가시키도록 되어 있다.In addition, the control unit 6 for operating the inflator 8 is connected to the ultrasonic sensor 11, the collision or collision in the control unit 6 to calculate the speed and distance of the vehicle from the ultrasonic sensor 11 as a measured signal If determined to occur, the control unit 6 is adapted to apply an explosion signal through the cable 7 to explode the inflator 8.
그리고 상기 실린더 하우징(2)의 전방쪽에는 피스톤(10)에 의해 내부공기를 유출시키기 위한 배기구멍(12)이 형성되어 있다.In addition, an exhaust hole 12 is formed at the front side of the cylinder housing 2 to allow the internal air to flow out by the piston 10.
이어 본 발명의 작동을 설명한다.Next, the operation of the present invention will be described.
차량 충돌 또는 추돌 직전에 초음파센서(11)에서 상대차량의 차속과 거리를 계측된 신호에 의해 연산하는 제어부(6)에서 충돌 내지는 추돌로 판단되면, 상기 제어부(6)는 케이블(7)을 통해 폭발신호를 인플레이터(8)에 인가시키게 된다.If it is determined that the collision or collision occurs in the control unit 6 which calculates the vehicle speed and distance of the relative vehicle by the measured signal in the ultrasonic sensor 11 immediately before the collision or collision, the control unit 6 uses the cable 7. The explosion signal is applied to the inflator 8.
그러면 상기 인플레이터(8)는 폭발하여 가스를 분출하게 되는데, 폭발된 가스는 가스구멍(9)을 통하여 실린더 하우징(2)의 피스톤(10)을 밀게 되는 바, 이때 이 피스톤(10)의 전방쪽 공기는 배기구멍(12)을 통하여 외기로 방출된다.Then, the inflator 8 explodes to eject gas, which pushes the piston 10 of the cylinder housing 2 through the gas hole 9, in which case the front side of the piston 10. Air is discharged to the outside air through the exhaust hole 12.
그리고 충돌 또는 추돌이 발생하면 범퍼 페이스(4)와 완충재(5)에서 1차충격이 흡수되고, 2차충돌은 상기 피스톤(10)내부의 폭발가스에 의하여 충격이 완화되면, 3차 충돌은 이 피스톤로드(3)보다 약간 길게 장착된 실린더 하우징(2)이 변형되면서 충격에너지를 흡수할 뿐만 아니라, 최종적으로 백빔(1)이 충돌하여 전체적인 충격에너지를 흡수하도록 되어 있다.When a collision or a collision occurs, the primary shock is absorbed by the bumper face 4 and the cushioning material 5, and the secondary collision is caused by the explosion gas inside the piston 10. The cylinder housing 2 mounted slightly longer than the piston rod 3 is deformed to absorb the impact energy, and finally the back beam 1 collides to absorb the overall impact energy.
더욱이 충격 흡수시 충돌시간을 지연시켜 탑승객의 상해치와 차체의 훼손을 저감시키도록 되어 있다.Furthermore, the impact time is delayed during shock absorption to reduce the passenger injury and damage to the vehicle body.
상기와 같이 본 발명에 따른 인출식 자동차용 범퍼는 충격에너지를 폭발가스를 이용하여 다단계로 흡수할 뿐만 아니라 충돌시간의 지연으로 탑승객의 상해치와차체 훼손을 최소화 시킬 수 있는 안전성의 향상을 가져온다.As described above, the bumper for pull-out vehicle according to the present invention not only absorbs the impact energy in multiple stages by using the explosive gas, but also improves the safety that can minimize the injury value of the passenger and damage to the vehicle due to the delay of the collision time.
