본 고안은 차량용 충격 흡수장치에 관한 것으로, 더욱 상세하게는 차체와 범퍼 사이에서 충격을 효과적으로 흡수함으로써 인명과 차체의 손상을 최소화하게 된 것이다.The present invention relates to a shock absorber for a vehicle, and more particularly, to minimize the damage to the human life and the vehicle by effectively absorbing the impact between the vehicle body and the bumper.
종래에도 차체의 전후면에는 차량의 충돌, 추돌시에 그 충격량을 최소화하기 위한 다양한 기구적 구성, 형태 및 소재의 범퍼 또는 충격흡수 수단이 제시되어 있다.Conventionally, bumpers or shock absorbing means of various mechanical configurations, shapes, and materials are proposed on the front and rear surfaces of a vehicle body to minimize the amount of impact during a collision or collision of a vehicle.
그러나, 상기한 종래 기술에서는 사고 발생시에 충격량 최소화라는 원래의 목적이 효과적으로 달성되지 못하여 차량이 손상됨으로써 많은 경제적 손실을 유발함은 물론, 차량에 탑승한 승차자에게도 충격이 직접 가해져 귀중한 인명의 손실이 유발된다는 문제점이 지적되고 있다.However, in the above-described prior art, the original purpose of minimizing the amount of impact at the time of an accident is not effectively achieved, causing damage to the vehicle, causing a lot of economic losses, and directly impacting the occupant on the vehicle, thus causing the loss of valuable lives. The problem is that it is pointed out.
특히, 종래의 범퍼는 총격을 받을 경우 그 자체가 형태 변형 즉 파손되므로 작은 충격이 가해질 경우에는 고가의 범퍼 자체를 교환해야만 한다는 문제점도 지적되고 있다.In particular, it is pointed out that the conventional bumper itself has to be replaced by an expensive bumper when a small impact is applied since it is itself deformed, that is, broken.
본 고안은 상기한 문제점들을 근본적으로 해소시킬 수 있는 차량용 충격 흡수장치를 제공함에 그 목적이 있으며, 상기 목적을 효과적으로 달성하기 위하여 본 고안에서는 차체와 범퍼 사이에 피스톤과 실린더를 설치하여 충격 부하시에 유압의 누출이 유발되도록 하여 충격을 흡수함과 동시에 충격 흡수 후에는 압축스트림의 복귀력에 의해 원래 상태로 복귀되도록 함으로써 충격흡수 효율의 극대화에 의해 차체와 인명 손상의 최소화가 구현되게 하였다.The object of the present invention is to provide a shock absorber for a vehicle that can fundamentally solve the above problems. In order to effectively achieve the above object, the present invention provides a piston and a cylinder between a vehicle body and a bumper, so The hydraulic leakage is induced to absorb the shock, and the shock stream is returned to the original state by the return force of the compressed stream, thereby minimizing damage to the vehicle body and life by maximizing the shock absorption efficiency.
이하에서 상기 본 고안의 양호한 실시예를 첨부도면에 의해 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail by the accompanying drawings.
본 고안 충격 흡수장치는 제1도에서와 같이 범퍼(1)에 고정 설치되며 그 외면에는 압축실(21) 상단과 회수실(22) 하단을 연결하도록 체크 밸브(23)를 포함하는 리턴통로(24)를 형성시킨 실린더(2)와, 상기 압축실(21)과 회수실(22)을 연결하는 유압통로(31)가 형성되어 차체(4)에 고정설치되는 피스톤(3)과, 상기 압축실(21)과 피스톤(3) 상단 사이에 압축 설치되어 복귀력을 제공하는 압축스프링(5)으로 구성된다.The shock absorber of the present invention is fixedly installed in the bumper 1 as shown in FIG. 1 and has a return passage including a check valve 23 connected to an upper end of the compression chamber 21 and a lower end of the recovery chamber 22 on the outer surface thereof. A cylinder (2) having a 24 formed therein, a hydraulic passage (31) connecting the compression chamber (21) and the recovery chamber (22) to form a piston (3) fixed to the vehicle body (4), and the compression Compression spring 5 is provided between the seal 21 and the upper end of the piston 3 to provide a return force.
이와 같은 구성의 본 고안은 차량의 운행중 충돌 또는 추돌에 의해 범퍼(1)에 충격이 가해질 경우, 범퍼(1)와 함께 실린더(2)도 후방으로 이동하게 된다.According to the present invention having the above configuration, when the impact is applied to the bumper 1 by collision or collision while the vehicle is running, the cylinder 2 together with the bumper 1 also moves rearward.
이에 따라 피스톤(3)은 전진하게 되므로 압축실(21)은 고압 상태가 되며, 이와 동시에 압축실(21)에 수용된 작용유는 피스톤(30의 유압통로(31)를 통해 회수실(22)로 이동하게 된다.Accordingly, since the piston 3 is advanced, the compression chamber 21 is in a high pressure state, and at the same time, the working oil contained in the compression chamber 21 is transferred to the recovery chamber 22 through the hydraulic passage 31 of the piston 30. Will move.
상기 작동은 강한 충격을 받는 경우에 발생하는 압축실(21)의 고압이 좁은 유압통로(31)를 통해 회수실(22)로 서서히 이동되는 즉, 충격을 흡수하는 결과로 나타나며, 상기 작동에 따라 압축스프링(5)로 압축되면서 충격을 흡수하게 되므로 충격 흡수 효율은 극대화 된다.The operation occurs as a result of the high pressure of the compression chamber 21 generated in the event of a strong shock is gradually moved to the recovery chamber 22 through the narrow hydraulic passage 31, that is, absorbs the shock, according to the operation Since the shock is absorbed while compressed by the compression spring (5), the shock absorption efficiency is maximized.
한편, 상기 작동시에 압축실(21)과 회수실(22) 사이에 연통 설치된 리턴통로(24)는 체크밸브(23)에 의해 폐쇄 상태를 유지하게 된다.On the other hand, during the operation, the return passage 24 provided between the compression chamber 21 and the recovery chamber 22 is kept closed by the check valve 23.
상기한 충격 흡수 후에는 압축스프링(5)의 복귀력에 의해 범퍼(1)를 포함하는 실린더(2)는 원위치로 복귀되는데, 이때에는 회수실(22)에 이동된 작동유는 피스톤(3)의 유압통로(31)와 리턴통로(24)를 통해 압축실(21)로 신속히 이동되어 초기 상태로서 또 다른 충격을 대기하게 된다.After the shock absorption described above, the cylinder 2 including the bumper 1 is returned to its original position by the return force of the compression spring 5. In this case, the hydraulic oil moved to the recovery chamber 22 is transferred to the piston 3. The hydraulic passage 31 and the return passage 24 are quickly moved to the compression chamber 21 to wait for another shock as an initial state.
이와 같이 본 고안은 차량의 충돌, 추돌시에 발생하는 충격을 효과적으로 흡수함과 동시에 신속히 원상 회복되므로, 충격 흡수 효율의 극대화에 의해 차체와 인명의 손상 및 경제적 손실의 최소화를 구현할 수 있게 된 유용한 고안이다.As such, the present invention effectively absorbs shocks generated during collisions and collisions of vehicles and restores the original condition quickly. Therefore, the present invention is useful to realize minimization of damage and economic loss of the vehicle body and life by maximizing the shock absorption efficiency. to be.
