Abstract

A bumper having a supplementary mechanism to absorb collision shock comprises a pair of slidable support arms (5) hinged at both ends of a bumper frame (1), and a pair of belt drums (20) with a belt (24) mounted on each end of the support arms. The support arms, each of which is slidable backward and has first and second coil springs (25,26) to be compressed, are stretched by a pair of expandable members (16) when they are released from manuallyoperated hooks (29). The expandable member consists of a piston (17) and a cylinder (18) actuated by a coil spring (19). The belt may be automatically rewound by a rotatable rewinding member (22) in the belt drum when the support arms are folded.

본 발명은 주행하던 자동차가 피충돌물과 충돌할 때 완충작용을 하여 인명피해을 포함한 여러가지의 피해를 축소시키기 위한 자동차의 완충장치에 관한 것이다.The present invention relates to a shock absorber of a vehicle for reducing a variety of damages, including human injury, by buffering when a driving vehicle collides with a collision object.

일반적으로 자동차의 충돌사고 중에서는 자동차 주행중에 피충돌물(사람포함)이 주행 안전거리 이내에서 별안간 발견되어 브레이크를 밟았으나, 차량의 관성에 의하여 어쩔 수 없이 충돌하는 경우가 많은데, 본 발명은 상기와 같은 상황에서 2차적으로 완충장치를 동작시켜 피충돌물과의 접촉시 충격을 완화시켜 인명피해를 포함하느 충돌로 인한 피해를 극소화 시키고자 개발한 것이다.In general, in a car crash accident, a collision object (including a person) is suddenly found within a driving safety distance and is braked while driving, but the vehicle inevitably collides due to the inertia of the vehicle. In this situation, it was developed to minimize the damage caused by collisions including human injury by mitigating the impact of contact with the impact object by operating the shock absorber secondarily.

이를 도면에 따라 상세히 설명하면 다음과 같다.This will be described in detail with reference to the drawings.

1은 기대로서, 양측에 절개부(2)를 형성하고 정면에 요홈(3)과 돌턱(4)은 중앙으로부터 대칭되게 형성한다. 5는 상기 기대(1) 양측에 설치되는 한쌍의 완충 아암으로, 내측에 활동개구(6'(7')을 가진 내, 외벽(6)(7)과 걸림턱(9)을 형성하고 내부 공간(8)에 원통 레일(10)을 설치한다. 11은 상기의 완충 아암(5)을 기대(1)의 양측에 회동자재토록 연결하는 연결구로서, 선단에 상기의 원통 레일(10)이 관총하는 관통공(11')을 천공하고 후단은 상기 기대(1) 양측의 절개부(2)에 핀(12)으로 회동 자재토록 설치되며 그 후방에 록크홈(13)이 형성되어 절개부(2)의 하방에 스프링(15)으로 탄동되는 록크핀(14)과 결합된다.1 is a base, the incision part 2 is formed in both sides, and the recessed part 3 and the protrusion 4 are formed symmetrically from the center in the front. 5 is a pair of shock absorbing arms provided on both sides of the base 1 to form an inner and outer walls 6 and 7 and a latching jaw 9 having an active opening 6 '(7') inside. A cylindrical rail 10 is provided at (8), and 11 is a connector for connecting the above-mentioned buffer arm 5 to both sides of the base 1 so as to rotate freely. The through hole 11 'is drilled and the rear end is pivotally installed on the cutouts 2 on both sides of the base 1 with pins 12, and a lock groove 13 is formed behind the cutout 2 It is coupled with the lock pin 14 is driven by the spring 15 below.

16은 신축 아암으로, 스프링(19)으로 탄발되는 피스톤(17)과 실린더(18)로 구성되며 실린더(18)의 후단은 상기 기대(1)의 요홈(3)에 회동 자재토록 유설되며 피스톤(17)의 선단은 걸림턱(17')을 형성하여 이 걸림턱(17')이 완충 아암(5)의 내·외벽(6)(7) 사이에서 활동토록 한다.16 is a telescopic arm, which is composed of a piston 17 and a cylinder 18 that is shot with a spring 19, and the rear end of the cylinder 18 is rotatably disposed in the groove 3 of the base 1, and the piston ( A tip of 17) forms a locking jaw 17 'such that the locking jaw 17' is active between the inner and outer walls 6 and 7 of the buffer arm 5.

20은 벨트드럼으로, 상기 완충 아암(5)의 선단에 대칭되게 연장부(20')로 고정되며 내부에 축(21)과 회전원통(22)을 설치하되 축(21)과 회전원통(22) 사이에 코일 스프링(23)을 게재시켜 코일 스프링(23)의 일단은 축(21)에 고정하고 타단은 회전원통(22)에 고정시키며, 양쪽 벨트드럼(20) 사이에 벨트(24)를 연결하되 벨트(24)의 양단을 상기 회전원통(22)에 고정하여 완충 아암(5)이 전개될 때는 회전원통(22)이 벨트(24)에 풀리는 힘에 의해 풀림방향으로 강제회전 되었다가 완충 아암(5)이 절첩될 때 회전원통(22)이 스프링(23)의 힘에 의해 감김방향으로 회전하면서 벨트(24)를 감아준다.20 is a belt drum, which is fixed to the extension portion 20 'symmetrically to the tip of the buffer arm 5, and has a shaft 21 and a rotating cylinder 22 therein, the shaft 21 and the rotating cylinder 22. The coil spring 23 is placed between the two ends so that one end of the coil spring 23 is fixed to the shaft 21 and the other end is fixed to the rotating cylinder 22, and the belt 24 is sandwiched between both belt drums 20. When both ends of the belt 24 are secured to the rotary cylinder 22 so that the shock absorbing arm 5 is developed, the rotary cylinder 22 is forcedly rotated in the disengaging direction by a force released by the belt 24, and then cushioned. When the arm 5 is folded, the rotary cylinder 22 winds the belt 24 while rotating in the winding direction by the force of the spring 23.

25, 26은 원통형 레일(10)에 설치되는 1, 2차 완충 스프링으로, 연결구(11)와 선단의 벨트드럼(20)의 연장부(20')사이에서 탄발작용을 하며 워셔(27)를 중간에 두고 후방에는 1차 완충 스프링(25)을, 전방에는 2차 완충 스프링(26)을 배치한다. 28은 좌우 한쌍으로 된 괘지구로서, 선단의 걸고리(29)는 기대(2)의 정면으로 표출되어 완충 아암(5)의 걸림턱(9)을 걸도록 되어 잇으며, 축(30)을 중심으로 회전하고 후단은 레버(31)에 연결하되 스프링(32)으로 탄설하며 레버(31')는 운전석에서 원격조정 가능케 한다.25 and 26 are primary and secondary shock absorbing springs installed on the cylindrical rails 10, and act as a springing force between the connector 11 and the extension portion 20 'of the belt drum 20 at the distal end. In the middle, the primary shock absorbing spring 25 is arranged in the rear, and the secondary shock absorbing spring 26 is arranged in the front. 28 is a left and right pair of hanging strips, and the hooks 29 at the tips are exposed to the front of the base 2 so as to hook the latching jaw 9 of the buffer arm 5 and center the shaft 30. Rotate to the rear end is connected to the lever 31, but the spring 32 and the lever (31 ') allows the remote control from the driver's seat.

이상과 같은 본 발명은 기대(1)가 제6도에서 나타낸 바와 같이 자동차의 범퍼 대신 설치사용 되는 것으로, 평상시에는 제6도와 같이 절첩된 상태에서 운행되며 이때는 기대(1) 양측에 설치된 완충 아암(5)이 괘지구(28)의 걸고리(29)에 의해 절첩상태가 유지되다가(제5(a)도 참조), 사고 발발시 운전자가 레버(31)를 동작시키면 레버(31)가 괘지구(28)의 후단을 밀어 괘지구(28)의 선단 걸고리(29)를 완충 아암(5)의 걸림턱(9)으로부터 해제시켜 주며, 이때 완충 아암(5)은 신축 아암(16)의 스프링(19)의 탄발력에 의해 탄발하려는 피스톤(17)의 힘에 의해 제5(b)도와 같이 양쪽으로 전개됨과 동시에, 완충 아암(5)의 후단에 설치된 연결구(11)의 록크홈(13)에 록크핀(14)이 록크되어 완충 아암(5)은 기대(1)와 수직상태를 유지하게 된다. 이때 완충 아암(5)의 전개에 따라 양쪽 벨트드럼(20) 내의 벨트(24)가 펼쳐지게 되며 이러한 상태에서의 벨트(24)는 모두 풀려져 있는 상태로서 더이상 풀릴 여지가 거의 없는 상태이다. 이러한 상태에서 벨트(24)가 피충돌물체(사람을 포함한다)에 부딪치면 제5(c)도와 같이 완충 아암(5)이 후퇴하면서 완충작용을 단계적으로 하게 된다.In the present invention as described above, the base 1 is used instead of the bumper of the vehicle as shown in FIG. 6, and is normally operated in a folded state as shown in FIG. 6, and in this case, the shock absorbing arms installed on both sides of the base 1 5) The folded state is maintained by the hook 29 of the ruler 28 (see also fifth (a)). If the driver operates the lever 31 at the time of an accident, the lever 31 moves to the ruler ( The rear end of 28 is pushed to release the front end hook 29 of the ruler 28 from the latching jaw 9 of the buffer arm 5, wherein the buffer arm 5 is a spring 19 of the telescopic arm 16. By the force of the piston 17 to be repulsed by the repulsive force of), it expands to both sides as shown in FIG. 5 (b) and locks to the lock groove 13 of the connector 11 provided at the rear end of the buffer arm 5. The pin 14 is locked so that the buffer arm 5 is perpendicular to the base 1. At this time, according to the development of the buffer arm 5, the belts 24 in both belt drums 20 are unfolded, and in this state, the belts 24 are all released and there is little room for release. When the belt 24 hits the object to be impacted (including a person) in this state, the buffer arm 5 retreats as shown in FIG.

즉, 제1단계 완충작용은 1차 완충 스프링(25)이 수축되면서 이루어지고 1차 완충 스프링(25)이 어느 정도 충격을 흡수하고 나머지 여분의 충격은 2차 완충 스프링(26)이 수축되면서 충격을 완전히 흡수하는 것이다.That is, the first stage buffering action is made as the primary buffer spring 25 is contracted and the primary buffer spring 25 absorbs a certain amount of shock and the remaining extra shock is impacted as the secondary buffer spring 26 is contracted. Is to absorb it completely.

위와 같이 완충작용을 하는 본 발명은 일단 동작된 후에는 상기 동작의 역순으로 하여 인위적으로 절첩괘지시키면 원상 복귀된다.The present invention, which has a buffer function as described above, returns to its original state when it is artificially folded and held in the reverse order of the above operation.

상기한 바와 같은 본 발명은 차체의 외관을 해치지 않는 매우 간단한 구조로써 자동차의 충돌사고에 대비한 것으로 인명피해 등의 제반피해를 극소화시켜 운전자와 피해자에게 자동차의 위험부담을 크게 덜어줄 수 있는 특징을 지닌 것이다.The present invention as described above is a very simple structure that does not harm the appearance of the car body to prepare for a crash accident of the car to minimize the damages such as personal injury and the like can greatly reduce the risk of the vehicle to the driver and the victim I have it.
