위와 같이 구성된 본 발명의 실시예를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.An embodiment of the present invention configured as described above will be described in detail with reference to the accompanying drawings.
도 2 에 나타낸 바와 같이, 범퍼(10)는 사이드 프레임(13)의 전단에 백빔(12)을 결합시키되, 백빔(12)의 배면에 브래킷(14)를 부착하여 사이드 프레임(13)에 삽입하고, 브래킷(14)의 외주연에 코일 스프링(15)을 끼워 고정시킨다.As shown in FIG. 2, the bumper 10 couples the back beam 12 to the front end of the side frame 13, and attaches the bracket 14 to the rear surface of the back beam 12 to insert the side beam 13. , The coil spring 15 is fixed to the outer periphery of the bracket (14).
또한, 백빔(120의 전면에 범퍼 커버(11)를 결합시키고, 브래킷(14)의 후측 사이드 프레임(13) 내부에 주름탱크(16)를 설치하고, 주름탱크(16)의 후측에 공기 배출공(17)을 형성하되, 상기 공기 배출공(17)에 삽입되는 댐핑 핀(19)을 형성한 판 스프링(18)를 주름탱크(16)의 배면에 부착한다.In addition, the bumper cover 11 is coupled to the front surface of the back beam 120, and the corrugation tank 16 is installed inside the rear side frame 13 of the bracket 14, and the air exhaust hole is provided at the rear side of the corrugation tank 16. (17) is formed, and a leaf spring (18) having a damping pin (19) inserted into the air discharge hole (17) is attached to the rear surface of the corrugation tank (16).
작동부(20)는 상기 범퍼(10)의 주름탱크(16)에 에어탱크(23)를 공기 공급관(21)으로 연결하여 연통시키고, 공기 공급관(21)에 솔레노이드 밸브(22)를 설치한다.The operation unit 20 connects the air tank 23 to the corrugated tank 16 of the bumper 10 by the air supply pipe 21 to communicate with each other, and installs the solenoid valve 22 in the air supply pipe 21.
제어부(30)는 상기 작동부(20)의 솔레노이드 밸브(22)에 콘트롤 유니트(31)를 접속시키되, 콘트롤 유니트(31)의 입력단에 차량의 전방물체를 감지하는 거리 감지센서(32)와 차량의 현재속도를 감지하는 가속도센서(33)를 접속시킨다.The control unit 30 connects the control unit 31 to the solenoid valve 22 of the operation unit 20, and the distance detecting sensor 32 and the vehicle detecting the front object of the vehicle at the input terminal of the control unit 31. Connect the acceleration sensor 33 to detect the current speed of.
이러한 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention as follows.
차량의 주행중 전방에 장애물체나 주행차량등과 충돌우려가 있는 경우, 즉 가속도센서(33)와 거리 감지센서(32)의 값을 콘트롤 유니트(31)에서 센싱하여 이를 비교분석하고, 이때 분석값이 일정값 이하로 설정되어 차량의 충돌우려가 발생되면 솔레노이드 밸브(22)에 전원을 인가하여 솔레노이드 밸브(22)를 오픈시켜 에어탱크(23)의 공기를 공기 공급관(21)을 통하여 주름탱크(16)에 공급하여 주름탱크(23)를 팽창시킴과 동시에 내부압력을 상승시킴으로써, 주름탱크(16)의 팽창으로 브래킷(14)이 전방으로 밀려 범퍼(10)가 전방으로 돌출된다.When there is a possibility of collision with an obstacle or a traveling vehicle in front of the vehicle while driving, that is, the values of the acceleration sensor 33 and the distance sensor 32 are sensed by the control unit 31 and compared and analyzed. When the vehicle is set to a predetermined value or less and there is a concern of collision, the solenoid valve 22 is applied to open the solenoid valve 22 to supply air to the air tank 23 through the air supply pipe 21. 16 to expand the corrugated tank 23 and at the same time increase the internal pressure, the expansion of the corrugated tank 16 pushes the bracket 14 forward and the bumper 10 protrudes forward.
이때 차량이 충돌하게 되면, 폐단면을 형성한 백빔(12)이 1차로 충격을 흡수하고, 다시 2차로 주름탱크(16)가 충격을 감쇠시킴과 동시에 주름탱크(16)의 충격에 의한 압력상승으로 판 스프링(18)의 탄성으로 공기 배출공(17)을 차단시킨 댐핑핀(19)을 밀어 공기를 외부로 배출시켜 충격 감쇠력을 증대시킨다.At this time, when the vehicle collides, the back beam 12 having the closed cross section absorbs the shock first, and the corrugation tank 16 attenuates the shock secondly, and at the same time, the pressure increases due to the impact of the corrugation tank 16. By pushing the damping pin 19 to block the air outlet hole 17 by the elasticity of the leaf spring 18 to discharge the air to the outside to increase the impact damping force.
이상에서 살펴본 바와 같이, 본 발명은 차량의 충돌 가능성을 주행중에 감지하여 충돌전 범퍼의 충격 에너지에 대한 감쇠능력을 배가시켜 충돌 발생시 충격량을 범퍼에 최대한 흡수시킴으로써, 차량의 손상을 최소로 줄일 뿐 아니라, 운전자의 탑승자를 최대한 보호하여 안전성을 극대화시킬 수 있는 것이다.As described above, the present invention detects the possibility of collision of the vehicle while driving and doubles the damping ability of the impact energy of the bumper before the collision, thereby absorbing the impact amount to the bumper as much as possible, thereby reducing damage to the vehicle to a minimum. In addition, the driver's occupant can be protected as much as possible to maximize safety.
