Description
본 고안은 자동차의 충격완화장치에 관한 것으로, 특히 자동차의 후방부를 다른 차량이 추돌할 때 차체로 전달되는 충격을 완화시키고, 다른 차량이 자동차의 후방시트 부분으로 밀려들어오지 않도록 함으로써 후방시트에 착석한 탑승자를 보호할 수 있도록 되어 있는 자동차의 충격완화장치에 관한 것이다.The present invention relates to a shock absorber of an automobile, and in particular, to reduce the shock transmitted to the vehicle body when another vehicle collides with the rear of the vehicle, and to prevent the other vehicle from being pushed into the rear seat portion of the vehicle, The present invention relates to a shock absorber of a vehicle configured to protect a passenger.
일반적으로 자동차에는 주행중 충돌시에 탑승자를 보다 안전하게 보호하기 위해 충격완화범퍼가 차체의 전후방에 장착되어 있는 바, 이 충격완화범퍼는 제일 바깥쪽에 장착되어 외관미를 향상시키는 페시아와, 이 페시아의 이면에 결합되어 자동차가 충돌되거나 추돌될 경우에 충격에너지를 1차적으로 흡수하는 발포고무와 같은 재질로 된 충격흡수재및, 이 충격흡수재의 이면에 결합되어 충격완화범퍼의 구조적인 강성을 증대시킴과 더불어 충격을 2차적으로 흡수하기 위해 범퍼스테이를 개재하여 차체와 체결되는 충격흡수빔을 갖춘 구조로 되어 있다.In general, in order to protect the occupants more safely in the event of a crash while driving, a shock-absorbing bumper is mounted on the front and rear of the vehicle body. Coupled to the shock absorber made of a material such as foam rubber that absorbs the impact energy primarily when the vehicle collides or collides, and increases the structural stiffness of the shock-absorbing bumper by being coupled to the back of the shock absorber. In order to absorb shock secondaryly, it has a structure with a shock absorbing beam that is fastened to the vehicle body via a bumper stay.
그런데, 이러한 구조를 갖는 충격완화범퍼는 자동차의 후방부에 고정부착되어 있어, 다른 차량이 심하게 충돌하는 경우에는 충격완화가 제대로 이루어지지 않을뿐 아니라, 충돌이 심할 경우에는 충격완화범퍼가 차체 측으로 휘어지면서 후방시트에 착석해 있는 탑승자가 부상을 입게 된다는 문제점이 있었다.However, the shock-absorbing bumper having such a structure is fixedly attached to the rear of the vehicle, so that in case of severe collision with other vehicles, the shock-absorbing bumper is not properly performed. There was a problem in that the occupants sitting on the rear seats were injured.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 자동차의 후방부를 다른 차량이 추돌할 때 차체로 전달되는 충격을 완화시키고, 다른 차량이 자동차의 후방시트 부분으로 밀려들어오지 않도록 함으로써 후방시트에 착석한 탑승자를 보호할 수 있도록 되어 있는 자동차의 충격완화장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, to alleviate the shock transmitted to the vehicle body when another vehicle collides the rear portion of the vehicle, and to prevent the other vehicle is not pushed to the rear seat portion of the vehicle rear seat It is an object of the present invention to provide a shock absorber of a vehicle that is capable of protecting a passenger seated at the vehicle.
상기의 목적을 달성하기 위한 본 고안은, 자동차의 후방부에 설치되는 실린더와, 실린더 내부의 헤드부분에 설치되어 소정치 이상의 압력이 가해질 때 폭발하는 폭발장치와, 자동차의 후방부 외측에 설치되고 실린더실 내에 수용된 피스톤의 헤드 반대측에 고정설치된 강성체로 된 연결바의 단부에 고정되며 폭발장치의 폭발에 의해 자동차의 후방부로부터 외측으로 이격되는 빔형상을 갖는 충격완화범퍼로 이루어지는 자동차의 범퍼충격완화장치에 의해 달성된다.The present invention for achieving the above object is a cylinder installed in the rear of the vehicle, an explosion device which is installed in the head portion inside the cylinder and explodes when a predetermined pressure or more is applied, and is installed outside the rear of the vehicle and Bumper shock mitigation of a vehicle, which is fixed to an end of a rigid connection bar made of a rigid body opposite to the head of a piston housed in a cylinder chamber, and has a beam-releasing bumper having a beam shape spaced outward from the rear of the vehicle by an explosion of an explosion device. Achieved by the device.
상기한 기술구조에 의해, 다른 차량이 자동차의 후방부의 충격완화범퍼에 충돌할 때에는, 충격완화범퍼가 실린더의 헤드부분으로 소정거리 이격되어 폭발장치를 가압하여 폭발장치가 폭발함으로써 충격완화법퍼가 자동차의 후방부 외측으로 밀리면서 다른 차량을 밀게 된다. 이에 따라, 충돌시 차체로 전달되는 충격이 완화되고 자동차의 후방시트로 다른 차량이 밀고 들어오는 것이 차단되어 후방시트에 착석한 탑승자가 보호될 수 있게 된다.According to the above-described technical structure, when another vehicle collides with the impact releasing bumper at the rear of the vehicle, the impact releasing bumper is spaced a predetermined distance to the head of the cylinder, pressurizes the explosive device, and the explosion device explodes. Pushing out of the rear of the car will push another vehicle. Accordingly, the impact transmitted to the vehicle body in the event of a collision is alleviated, and other vehicles are pushed in and out of the rear seat of the vehicle, thereby protecting the occupant seated on the rear seat.

도 1은 본 고안에 따른 범퍼충격완화장치가 장착된 자동차의 측면도이고, 도 2는 도 1의 범퍼충격완화장치의 사시도이다. 이들 도면에 도시된 바와 같이, 자동차의 차체 전후방부에는 주행중 충돌시에 탑승자를 보다 안전하게 보호하기 위해 빔형상의 충격완화범퍼(1a, 1b)가 설치되어 있다. 이들 충격완화범퍼(1a, 1b) 중 자동차의 후방부에 설치되는 충격완화범퍼(1b)는 본 고안에 따른 범퍼충격완화장치를 구성하게 되는 바, 자동차 후방부의 충격완화범퍼(1b)에 인접한 차체에는 실린더(3)가 설치되어 있고, 실린더(3) 내부의 헤드부분에는 소정치 이상의 압력이 가해졌을 때 폭발하게 되는 폭발장치(5)가 장착되어 있다. 실린더(3) 내부에는 피스톤(7)이 수용되어 왕복동할 수 있도록 되어 있고, 피스톤(7)의 헤드 반대측에 고정설치되는 강성체로 된 연결바(9)의 단부가 충격완화범퍼(1b)에 고정되어 있다.1 is a side view of a vehicle equipped with a bumper shock absorber according to the present invention, Figure 2 is a perspective view of the bumper shock absorber of FIG. As shown in these figures, the front and rear parts of the vehicle body are provided with beam-shaped shock alleviating bumpers 1a and 1b in order to protect the occupants more safely during a collision during driving. Among these shock-absorbing bumpers 1a and 1b, the shock-absorbing bumper 1b installed at the rear of the vehicle constitutes a bumper shock-absorbing device according to the present invention. The cylinder 3 is provided, and the head part inside the cylinder 3 is equipped with the explosion apparatus 5 which will explode when a pressure more than a predetermined value is applied. The piston 7 is accommodated inside the cylinder 3 so as to reciprocate, and an end portion of the rigid connection bar 9 fixed to the head opposite side of the piston 7 is fixed to the shock absorber 1b. It is.
이러한 구성에 의하여, 다른 차량이 자동차의 후방부의 충격완화범퍼(1b)에 충돌할 때에는, 도 3 및 도 4에 도시된 바와 같이 충격완화범퍼(1b)가 실린더(3)의 헤드부분으로 소정거리 이격되어 폭발장치(5)를 가압하여 폭발장치(5)가 폭발함으로써 충격완화법퍼가 자동차의 후방부 외측으로 밀리면서 다른 차량을 밀게 된다. 이에 따라, 충돌시 차체로 전달되는 충격이 완화되고 자동차의 후방시트(11)로 다른 차량이 밀고 들어오는 것이 차단되어 후방시트(11)에 착석한 탑승자가 보호될 수 있게 된다.By such a configuration, when another vehicle collides with the impact alleviating bumper 1b of the rear part of the vehicle, the impact alleviating bumper 1b moves a predetermined distance to the head portion of the cylinder 3 as shown in FIGS. 3 and 4. Pressing the explosive device 5 is spaced apart to explode the explosive device 5, the impact relaxation method is pushed to the outside of the rear portion of the vehicle to push another vehicle. Accordingly, the impact transmitted to the vehicle body in the event of a collision is alleviated and other vehicles are pushed in and out of the rear seat 11 of the vehicle so that the occupant seated on the rear seat 11 can be protected.
이상 설명한 바와 같이 본 고안에 따른 자동차의 범퍼충격완화장치에 의하면, 자동차의 후방부를 다른 차량이 추돌할 때 차체로 전달되는 충격을 완화시키고, 다른 차량이 자동차의 후방시트(11) 부분으로 밀려들어오지 않도록 함으로써 후방시트(11)에 착석한 탑승자를 보호할 수 있는 효과가 있게 된다.As described above, according to the bumper shock absorber of a vehicle according to the present invention, the shock transmitted to the vehicle body is alleviated when another vehicle collides with the rear part of the vehicle, and the other vehicle is not pushed into the rear seat 11 of the vehicle. By doing so, there is an effect that can protect the occupant seated on the rear seat (11).
