본 발명은 차량 추돌시 순간적으로 작동하여 운전자는 물론 조수석의 동승자도 동시에 보호함은 물론 사고차량의 수리후 재운행시에 다시 안전장치로 사용할 수 있으며 적은 비용으로 설치가 가능한 자동차의 안전장치에 관한 것이다.The present invention relates to a safety device of a vehicle which can be operated instantaneously during a vehicle crash to protect not only the driver but also the passenger of the passenger seat at the same time, and can be used as a safety device again when the accident vehicle is repaired and can be installed again at a low cost. .
현재는 자동차 추돌시 운전자를 보호할 수 있도록 핸들 전면에 에어백을 설치하여 차량 추출과 도시에 에어빽이 순간적으로 팽창되어 운전자를 보호하고 있다.Currently, airbags are installed on the front of the steering wheel to protect the driver in the event of a car crash.
그러나 이것은 가격이 고가이며 한번 사용후에는 재사용이 불가능할 뿐 아니라 운전자의 옆의 동승자는 보호하지 못하는 문제로 차량추돌시 조수석에 탑승한 사람은 거의 무방비상태로 노출되어 있다.However, it is expensive and cannot be reused once used, and the driver next to the driver cannot be protected.
조수석에도 에어백을 설치할 수 있으나 대부분 설치비용이 고가인 관계로 조수석에는 설치하지 않고 안전벨트에 의존하고 있으나 충격이 심할 경우 안전벨트로 인해 또다른 부상을 당하는 경우가 자주 발생하였다.Airbags can be installed in the passenger seat, but most of them are expensive, so they are not installed in the passenger seat but rely on the seat belt. However, when the impact is severe, they are often injured by the seat belt.
본 발명은 이와같은 문제점을 해결하기 위한 것이며 차량추돌시 운전자는 물론 조수석에 탑승한 동승자도 동시에 보호할 수 있고 또한, 충격을 다소나마 흡수완화시킬 수 있도록 하여, 차량의 손상을 최소한으로 방지할 수 있도록 하며 또, 차량을 폐차시키지 않는 한 재사용할 수 있는 안전장치를 제공함에 그 목적을 있는바, 이와같은 본 발명의 구성을 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention is to solve such a problem and to protect not only the driver but also the passenger occupying the passenger seat at the time of the vehicle crash, and also to absorb the shock somewhat somewhat, to prevent damage to the vehicle to a minimum In addition, the purpose of the present invention is to provide a safety device that can be reused unless the vehicle is decommissioned. The configuration of the present invention will be described in detail with reference to the accompanying drawings.

It is configured to support.
이와같은, 제동축(6)의 후단에는 2차적인 완충작용과 안전장치의 연동작용을 위한 실린더(7)가 연결되어 있다.As such, the rear end of the brake shaft 6 is connected to the cylinder 7 for the secondary shock absorbing action and the interlocking action of the safety device.
실린더(7) 전단에는 제동축(6)의 밀판(8)이 끼워지고 후단에는 연동로드(9)의 받침판(9a)이 끼워지며, 이들 사이에 스프링(3A)이 받쳐져서 서로 반대로 밀려지도록 구성하고 있다.The front end of the cylinder (7) is fitted with the closing plate (8) of the braking shaft (6), the back end is fitted with the support plate (9a) of the interlocking rod (9), the spring (3A) between them is supported so as to be pushed against each other. Doing.
또한, 연동로드(9)의 받침판(9a) 뒷면과 실린더(3b)의 후벽면 사이에는 또 다른 스프링(3b)을 설치하여 받침판(9a)이 전방쪽으로 밀려지게 하므로서 전·후방의 스프링(3a)(3b)이 이중으로 완충작용을 하도록 구성한 것이다.In addition, another spring 3b is provided between the back surface of the supporting plate 9a of the interlocking rod 9 and the rear wall surface of the cylinder 3b so that the supporting plate 9a is pushed forward and the front spring 3a is pushed forward. (3b) is configured to double the buffer.
연동로드(9)의 후단에는 실내의 안정장치와 연결되는 링크(10)가 연결되며, 링크(10)의 중앙부는 차체하단의 브라켓트(11)에 회동가능하게 연결하므로써 중앙 연결지점을 중심으로하여 상·하단이 반대로 회동하도록 구성한 것이다.The rear end of the interlocking rod (9) is connected to the link 10 is connected to the stabilizer in the room, the center of the link 10 is connected to the bracket 11 at the lower end of the vehicle body by rotating the center of the connection point The upper and lower ends are configured to rotate in reverse.
이렇게 고정된 연동로드(10) 일측상단은 차체(1)내의 운전석(12)고 조수석 중간뒤쪽의 바닥에 설치되는 포스트(20)내의 와이어로우프(21) 하단부와 연결한다.One side upper end of the fixed interlocking rod 10 is connected to the lower end of the wire rope 21 in the driver's seat 12 in the vehicle body 1 and the post 20 installed at the bottom of the rear of the passenger seat.
포스트(20)의 상단일측에는 지지축(24)이 경사형으로 연결되어 있으며, 지지축(24)의 상단부에 보호대(22)의 꼬리축(23)이 힌지식으로 결속되어 있다.The support shaft 24 is inclinedly connected to the upper end side of the post 20, and the tail shaft 23 of the guard 22 is hingedly coupled to the upper end of the support shaft 24.
그리고 보호대(22) 전방에는 발포우레탄재로 만든 쿳션(14)이 횡방향으로 길게 형성되고 후방의 꼬리축(24) 전단부에 와이어 로우프(21)의 상단부가 연결되어 있다.And the cushion 14 made of foamed urethane material is formed in the transverse direction in front of the guard 22, the upper end of the wire rope 21 is connected to the front end of the tail shaft 24 in the rear.
또한, 보호대(22)가 상방으로 들려진 상태를 유지하도록 차체천정(30)에는 클립(31)을 설치하였으며, 클립(31)은 탄성편을 이용하여 집게형으로 형성하므로서 외력에 의해서만 클립에서 쿳션이 이탈될 수 있는 것이다.In addition, a clip 31 is installed on the body ceiling 30 so as to keep the guard 22 lifted upwards, and the clip 31 is formed by the forceps using an elastic piece, so that the clip is secured by the external force. This can be deviated.
지지축(6)을 다수 설치하여 범퍼(5)와 접합시킨 이유는 범퍼(5)가 일반적인 운행중에는 흔들거림없는 안전성을 확보하기 위함이며 또 다른 이유는 범퍼(5)의 좌·우나 중앙어디에 부딪쳐도 본 발명의 안전장치가 작동되게 한것으로 실린더(7)에 끼워진 제동축(6)은 각각의 완충구(2)에 독립되게 연결되어 있어 어느곳에 충격이 가해지더라도 실린더(7)의 밀판(8)을 정확하게 밀어주어 안전장치가 작동하게 한것이다.The reason why a plurality of support shafts 6 are installed and bonded to the bumper 5 is to ensure that the bumper 5 is free from shaking during normal operation. Another reason is that the bumper 5 may be bumped into the left, right or center of the bumper 5. The braking shaft 6 fitted to the cylinder 7 by operating the safety device of the present invention is connected to each of the shock absorbing openings 2 independently, so that no matter where the impact is applied, the sealing plate 8 of the cylinder 7 It is pushed correctly to make the safety device work.
이와같이 된 본 발명의 범퍼(5)일측에 추돌로 인해 충격이 가해지면 범퍼(5)와 연접된 지지축(4)이 차체(1)의 운전석(12)쪽으로 밀리면서 완충구(2)의 스프링(3)이 지지축(4)의 연결핀(4a)에 밀려 수축되며 1차로 충격이 흡수됨과 동시에 제동축(6)후진하면서 실린더(7)내의 밀편(8)을 밀어준다. 그러면 연동로드(9)와 일체로된 받침판(9a)이 뒤쪽으로 밀려나게 된다.When a shock is applied to one side of the bumper 5 according to the present invention as described above, the support shaft 4 connected to the bumper 5 is pushed toward the driver's seat 12 of the vehicle body 1, and the spring of the shock absorber 2 is applied. (3) is pushed and contracted by the connecting pin (4a) of the support shaft (4) and the first shock is absorbed and at the same time pushes the push piece (8) in the cylinder (7) while the brake shaft (6) backwards. Then, the supporting plate 9a integrated with the interlocking rod 9 is pushed backward.
즉, 실린더(7)에 연접된 연동로드(9)의 받침판(9a)이 밀판(8) 및 스프링(3a)에 의해 밀리게 되고 받침편(9a)은 스프링(3b)은 압축하면서 뒤쪽으로 밀려난다.That is, the support plate 9a of the interlocking rod 9 connected to the cylinder 7 is pushed by the mill plate 8 and the spring 3a, and the support piece 9a is pushed backward while compressing the spring 3b. Flies
이렇게 작동과정에서 차체(1)에 전달되는 충격을 2~3번 스프링(3)(3a)(3b)이 흡수하여 최소한으로 감소시켜준다.In this way, the shock transmitted to the vehicle body 1 is absorbed by the springs 2, 3, 3, 3a, and 3b to minimize it.
이와동시에 연동로드(9)가 뒤로 밀려나면서 링크(10)의 중심부(A)를 지점으로 하단부는 차체 뒤쪽으로 밀려나고 상단부는 차체 앞쪽으로 회동하면서, 와이어로우프(21)를 아래로 당겨주게 되고, 그 즉시, 꼬리축(23)이 당겨지게 되어 차체 천정의 클립(31)에 물려져서 들려있던 쿳션(14)이 클립(31)에서 강제 이탈되면서 꼬리축 힌지부를 기점으로하여 원호상으로 낙하되어 운전자나 동승자의 전방부위를 받쳐주므로 추돌충격에 의해 운전자나 동승자나 외부로 튕겨 나가는 경우가 없고, 얼굴이나 가슴에 대한 충격을 완화시켜 안전하게 보호할 수 있는 것으로 완충구(2)와 실린더(7)를 공압이나 유압으로 대체하여서도 사용이 가능한 것이다.At the same time, as the interlocking rod 9 is pushed backward, the lower end is pushed toward the rear of the vehicle body by the center A of the link 10 and the upper end rotates toward the front of the vehicle body, and the wire rope 21 is pulled down. Immediately, the tail shaft 23 is pulled out so that the section 14, which is held up by the clip 31 of the body ceiling, is forcibly released from the clip 31 and falls to an arc shape from the tail shaft hinge as a starting point. (B) It supports the front part of the passenger, so that it does not bounce off to the driver, passenger or outside due to a collision shock, and it can protect the face and chest safely so that the shock absorber (2) and the cylinder (7) can be safely protected. It can be used by replacing with pneumatic or hydraulic.
이와같이된 본 발명은 범퍼에 충격이 심할수록 보호대의 움직이는 작동속도는 기계적인 특성에 의해 가속도가 붙어 더욱 빨리 작동하여 안전사고로부터 최대한으로 보호하여 주며 종래 일회사용에 한정하는 에어백에 비해서 저렴한 설치비용으로 월등한 효과를 얻을 수 있고 차체에 대한 충격완화 작용과 안전 쿳션 작용이 함께 하기 때문에 운전자에 대한 충격을 더욱 감소시킬 수 있는 효과가 있다.In the present invention as described above, the greater the impact on the bumper, the faster the moving speed of the protector is due to its mechanical properties, which accelerates faster and provides maximum protection from safety accidents. It is possible to reduce the impact on the driver because it is possible to obtain a superior effect and the impact reduction action on the body and the safety cushion action together.
