본 고안은 자동차 범퍼의 충격 흡수장치에 관한 것으로서, 더욱 상세하게는 차량이 주행시 충돌의 위험을 센서가 감지하여 실린더내에 가스를 충입시킴으로서, 범퍼가 전진하여 충돌의 충격을 흡수 인명피해나 차량의 손상을 방지하도록 한 자동차 범퍼의 충격 흡수장치에 관한 것이다.The present invention relates to a shock absorber of an automobile bumper, and more particularly, a sensor detects a risk of a collision while a vehicle is driving and injects gas into a cylinder, so that the bumper moves forward to absorb the impact of a collision. The present invention relates to a shock absorber of an automobile bumper.
일반적으로 차량의 충돌시 충격을 완화하는 장치로는 자체 프레임과 범퍼 사이에 복수개의 스프링을 장치하여 충격을 스프링의 탄성력으로 흡수하는 고안이 공지되어 있는데, 이는 범퍼에 부딪히는 충격을 흡수하는 스프링의 탄성력으로는 차체의 보호와 인명의 안전을 지키기위한 고안으로는 미흡하였다.In general, as a device for mitigating a shock during a collision of a vehicle, a device is known to absorb a shock by the elastic force of the spring by installing a plurality of springs between its own frame and the bumper, which is the elastic force of the spring to absorb the impact hit the bumper In order to protect the body of the body and to ensure the safety of human life, it was insufficient.
상기한 고안에서 충돌시 스프링에 전해지는 충격이 차체에 도달함과 동시에 스프링은 면과 면이 맞닿게 됨으로서 차체에 전해지는 충격은 그대로 전해지게 되어 앞서 제기한 인명의 보호와 차체의 안전에 대한 효과는 크게 기대할 수 없었다.In the above design, the impact transmitted to the spring at the time of collision reaches the vehicle body, and the spring is brought into contact with the surface, and the impact transmitted to the vehicle body is transmitted as it is. Could not have been greatly expected.
본 고안은 상기한 바와 같은 종래 고안의 문제점을 해소하기 위하여 안출된 것으로서, 본 고안의 목적은 차량이 주행시 충돌의 위험을 센서가 감지하여 실린더내에 가스를 충입시킴으로서, 범퍼가 전진하여 충돌의 충격을 흡수 인명피해나 차량의 손상을 방지하도록 한 자동차 범퍼의 충격 흡수장치를 제공하는데 있다.The present invention has been made to solve the problems of the conventional design as described above, the object of the present invention is to detect the risk of collision when the vehicle is driving the gas into the cylinder, so that the bumper moves forward to impact the impact It is to provide a shock absorber of an automobile bumper to prevent the absorption of life damage or damage to the vehicle.
이를 실현하기 위한 보고안은 범퍼의 양측부를 차체 프레임과 연결하여 주는 공압 실린더와 ; 상기 공압 실린더와 중공부재로 연통되며 내부에 가스가 충전된 봄베와 ; 충돌 예측 신호에 의하여 봄베 내의 가스를 인화 폭발시켜 주는 뇌관과 ; 충돌 예측을 감지하여 상기 뇌관이 동작되도록 신호를 보내주는 센서로 구성됨을 제공한다.Reports for realizing this include: a pneumatic cylinder connecting both sides of the bumper to the body frame; A cylinder communicating with the pneumatic cylinder and the hollow member and filled with gas therein; A detonator that flashes and explodes gas in the bomb by a collision prediction signal; It provides a sensor that detects the collision prediction and sends a signal to operate the primer.
이하 본 고안의 바람직한 실시예를 첨부한 도면에 따라 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
제1도는 범퍼에 감지장치가 장착되는 부위를 도시한 도면이고, 제2도는 본 고안의 일 실시예를 도시한 도면으로서, 부호 1은 범퍼를 지칭한다.FIG. 1 is a view showing a part in which a sensing device is mounted on a bumper, and FIG. 2 is a view showing an embodiment of the present invention, and reference numeral 1 designates a bumper.
상기 범퍼(1)는 양측부가 공압 실린더(2)에 의하여 프레임(3)에 고정되는데, 그의 후단부가 차체 프레임(3)에 고정되고, 그의 전측으로 형성된 피스톤(4)의 선단부가 범퍼 스테이(5)에 고정된다.The bumper 1 has both sides fixed to the frame 3 by a pneumatic cylinder 2, the rear end of which is fixed to the vehicle body frame 3, and the front end portion of the piston 4 formed at its front side is a bumper stay 5 It is fixed to).
그리고 상기 피스톤(4)의 선단에는 중공부재(6)가 연결되어 가스가 충전되어 있는 봄베(7)과 연통되어지고, 이의 봄베(7) 전측에는 충돌 예측 신호에 의하여 동작되는 뇌관(8)이 형성된다.A hollow member 6 is connected to the front end of the piston 4 to communicate with a cylinder 7 filled with gas, and a primer 8 operated by a collision prediction signal on the front side of the cylinder 7 is provided. Is formed.
상기 뇌관(8)은 범퍼(1)의 전면으로 설치되어 있는 초음파 센서(9)와 연결되어진다. 이에 따라 자동차의 주행중에 센서(9)에 의하여 충돌 예측 신호가 감지되면 이의 신호는 뇌관(8)으로 전달 되어지게 되며, 이의 신호를 받은 뇌관(8)은 동작되면서 봄베(7)내의 가스를 인화 팽창시키게 된다.The primer 8 is connected to the ultrasonic sensor 9 which is installed in front of the bumper (1). Accordingly, when a collision prediction signal is detected by the sensor 9 while driving the vehicle, the signal is transmitted to the primer 8, and the primer 8 receiving the signal is operated to ignite the gas in the bomb 7. Inflated.
그러면 팽창되는 가스는 중공부재(6)를 통해 범퍼(1) 양측을 지지하고 있는 공압 실린더(2)로 공급되어지게 되며, 이와같은 경로로 팽창가스가 공급된 공압 실린더(2)에는 공압의 증가로 인하여 그의 전측으로 형성되어 있는 피스톤(4)을 전측으로 밀어주어 범퍼(1)를 전방으로 밀어내게 된다.Then, the expanded gas is supplied to the pneumatic cylinder (2) supporting both sides of the bumper (1) through the hollow member (6), the pneumatic cylinder (2) supplied with the expansion gas in this way increases the pneumatic pressure By pushing the piston (4) formed on the front side to the front to push the bumper (1) forward.
이와같이 범퍼(1)가 돌출된 상태에서 충돌이 이루어지면 범퍼(1)는 다시 후측으로 후퇴하면서 공압실린더(2)내에 충진되어 있는 공압에 의하여 완충작용을 수행하게 되는 것이다.As such, when the collision occurs in the state in which the bumper 1 protrudes, the bumper 1 retreats to the rear side and performs a buffering action by the pneumatic pressure filled in the pneumatic cylinder 2.
상기한 센서(9)는 차량의 범퍼(1) 전면에 형성되어 일정속도 이상에서만 작동 되도록 되어 있어서, 주차시나 정지시에 다른 차량과 근접 거리를 유지하더라도 충격 흡수 장치가 작동하지 않도록 하였다.The sensor 9 is formed on the front of the bumper 1 of the vehicle to operate only at a predetermined speed or more, so that the shock absorbing device does not operate even when the vehicle is kept in close proximity to other vehicles during parking or stopping.
또한 평상시에는 제2도에서 부호(10)과 같이 프레임(3)에 부착되어 있는 공압 실린더(2)에 피스톤(4)이 전진하지 않고 완전 결합된 상태하에서 차량이 운행되게 되어 있다.In addition, the vehicle is normally operated in a state in which the piston 4 is fully engaged without advancing the pneumatic cylinder 2 attached to the frame 3 as shown by reference numeral 10 in FIG. 2.
이러한 본 고안의 효과는 충돌로 인하여 운전자와 차체에 미치는 충격이 실린더 내에 충입된 가스에 의해 충격 흡수 시간이 길어지게 됨으로서, 충돌에 의한 충격이 차체에 직접 전달되지 않아 차량의 보호와 운전자의 생명을 보호할 수 있는 매우 유용한 고안이다.The effect of the present invention is that the impact on the driver and the body due to the collision is extended by the gas charged in the cylinder, so that the impact of the impact is not transmitted directly to the body to protect the vehicle and the driver's life. It is a very useful design to protect.
