Description

자동차의 충격 완충장치{IMPACT ABSORBING DEVICE OF VEHICLES}IMPACT ABSORBING DEVICE OF VEHICLES}

본 발명은 자동차의 충격 완충장치에 관한 것으로서, 좀더 상세하게는 차동차의 전, 후면에 작동실린더에 의해 팽창하는 에어튜브를 구비하여 전후방은 물론 그 측방에서의 충돌 사고에 따른 충격을 효과적으로 완충하도록 하므로 사고의 피해를 최소화하는 자동차의 충격 완충장치에 관한 것이다.The present invention relates to a shock absorber of an automobile, and more particularly, having an air tube that is expanded by an operation cylinder on a front and a rear of a differential vehicle to effectively cushion a shock caused by a crash accident in the front and rear as well as the side thereof. The present invention relates to a shock absorber of a vehicle which minimizes the damage of an accident.

일반적으로 자동차 사고의 대부분은 자동차의 전,후면에서의 충돌에 따른 사고이다.In general, most of the car accidents are caused by collisions in the front and rear of the car.

이로인해 종래에는 고무합성수지와 같은 완충재를 차량의 전,후 범퍼의 양측방으로 부착하였으나, 이는 충격을 완충한다기 보다는 가벼운 충돌시 범퍼의 손상을 방지하는 역활 정도를 하는 것이었다.Due to this, in the past, a cushioning material such as a rubber synthetic resin was attached to both sides of the front and rear bumpers of the vehicle, but this was to play a role of preventing damage to the bumper during a light collision rather than cushioning the impact.

실제로 상기한 완충재만으로는 자동차에 가해지는 충격을 완화하는 것은 곤란하였다.In fact, it was difficult to alleviate the shock applied to the automobile only with the above-mentioned cushioning material.

이에 범퍼와 자동차 차체 사이로 각종 완충장치를 설치하는 구조가 다양하게 개시된 바 있는데, 대한민국 특허공보 제1996-8263호에서는 자동차의 전후 범퍼에 에어실린더를 연결하여서, 차량의 주행시 에어펌프에서 상기 에어실린더에 에어를공급하므로 전후 범퍼를 전후방으로 돌출시킨다.In this regard, various structures for installing various shock absorbers between the bumper and the vehicle body have been disclosed. In Korean Patent Publication No. 1996-8263, an air cylinder is connected to a front and rear bumper of a vehicle, so that the air cylinder is connected to the air cylinder during driving of the vehicle. As air is supplied, the front and rear bumpers protrude forward and backward.

이와 같은 상태에서 자동차의 충돌사고가 발생하면, 상기 범퍼에 가해지는 충격을 에어실린더가 완충하되, 상기 에어실린더는 일정 압력 이상에서 에어를 배출하므로서 가해진 충격을 흡수 상쇄시키게 된다.When a collision accident of a vehicle occurs in such a state, an air cylinder buffers the shock applied to the bumper, and the air cylinder absorbs and cancels the shock applied by discharging air at a predetermined pressure or more.

그러나, 상기한 충격 완충장치는, 충돌사고시 단순히 에어 실린더에 의해서만 충격을 완화하므로서, 그 충격완화가 효과적이 못하게 된다.However, the above-described shock absorber only dampens the impact only by the air cylinder in the event of a collision, so that the shock mitigation is not effective.

즉, 상기 에어실린더가 완충할 수 있는 한계 이상의 충격이 가해지는 경우에상기 에어실린더가 손상되면서 실질적으로 충격 완충의 기능을 수행하지 못하게 된다.That is, when an impact is applied beyond the limit that the air cylinder can cushion, the air cylinder is damaged and thus does not substantially function as a shock buffer.

특히, 자동차가 충돌사고가 자동차의 전후면에 정확히 일치하지 않고, 예를 들어 정면 45°방향이나 전후면의 측방에서 충격이 가해지는 경우에는 이러한 충격의 완충작동은 더욱 곤란하였다.In particular, in the case where the crash accident of the automobile does not exactly correspond to the front and rear surfaces of the vehicle, for example, an impact is applied in the front 45 ° direction or on the side of the front and rear surfaces, it is more difficult to cushion the shock.

외냐하면, 상기 에어실린더의 로드가 밀리면서 충격을 완화하는 방향과 엇갈리게 충격이 가해지면서 상기 에어실린더는 그 충격 완충작동을 하지 못하기 때문이다.In other words, the impact of the air cylinder is pushed against the direction to relieve the impact as the rod of the cylinder is pushed, the air cylinder does not perform the shock buffer operation.

또한, 상기한 완충장치는 평시에 자동차의 전후방 범퍼를 돌출된 상태를 유지해야만하므로 운전 등에 매우 불편한 문제점 등이 있다.In addition, the above-mentioned shock absorber has to maintain a protruding state of the front and rear bumpers of the vehicle in the usual time, there is a problem such as driving very inconvenient.

또한, 범퍼의 충돌로 인해 범퍼의 손상은 방치하기 때문에, 상기 범퍼의 잦은 교체로 인한 경제적 손실을 유발하게되는 것이다.In addition, since the bumper is left undamaged due to the bumper collision, it causes economic losses due to frequent replacement of the bumper.

본 발명은 상기한 종래 기술이 갖는 제반 문제점을 근본적으로 해결하고자 창출된 것으로서, 자동차의 전후방 정면에서 가해지는 충돌이나, 측면에서의 가해지는 충격 등에 대해 효과적으로 완충작동을 행하므로 안전사고의 피해를 최소화하는데 그 목적이 있다.The present invention was created to fundamentally solve all the problems of the prior art, and effectively minimizes the damage of safety accidents by effectively cushioning the impacts applied to the front and rear of the vehicle and the impact applied to the side. Its purpose is to.

또한, 본 발명은 평상시에는 완충수단이 차량에 밀착되게 설치된 상태를 유지하므로 편안하고, 안전한 운전을 제공하도록 하는데 그 목적이 있다.In addition, the present invention has an object to provide a comfortable, safe driving because the cushioning means is usually kept in close contact with the vehicle.

이러한 본 발명의 목적은, 자동차의 전후방 양측방에 전후방으로 탄발 유동하는 작동실린더를 설치하고, 그 실린더 로드 선단에 절첩되게 에어튜브를 구비하여 충돌에 의한 충격에 의해 상기 작동실린더가 작동하여 에어튜브를 펼치는 것에 의해 외부의 에어가 유입되어 에어튜브가 팽창하거나, 별도의 압축공기탱크내의 압축공기가 상기 에어튜브에 유입되어 팽창하도록 하므로서, 충돌에 따른 충격을 완화하므로 달성된다.The object of the present invention is to install an actuating cylinder in front and rear on both sides of the vehicle, and to provide the air tube to be folded at the front end of the cylinder rod so that the actuating cylinder is operated by the impact of the collision. By spreading the outside air is introduced to expand the air tube, or to compress the compressed air in a separate compressed air tank is introduced into the air tube to expand, thereby achieving the impact due to the impact.

즉, 본 발명은 도 1 내지 도 4에 도시된 바와 같이,That is, the present invention is shown in Figures 1 to 4,

자동차의 전후방 범퍼(3)(4)로 가해지는 충격을 완충하는 것에 있어서,In buffering the shock applied to the front and rear bumpers 3 and 4 of the vehicle,

상기 범퍼(3)(4)에는 좌우 양측방에 충돌을 감지하는 센서(미도시)에 의해 작동하는 작동실린더(10)를 전후방으로 각각 탄발 유동케 설치하고, 상기 작동실린더(10)의 로드(12) 선단에는 전후방향으로 절첩되는 자바라형의 에어튜브(20)를 설치하되, 상기 작동실린더(10)는 로드(12)의 신장으로 에어튜브(20)가 펼쳐지면서 그 외측방을 따라 다수 구비된 일방향 밸브(30)로 에어가 유입되어 팽창하도록 이루어진다.The bumper (3) (4) is installed in the front and rear operating cylinders (10) operated by a sensor (not shown) for detecting a collision in the left and right sides, respectively, and the rod of the operation cylinder (10) 12) the bellows-type air tube 20 is folded in the front and rear direction at the front end, the operation cylinder 10 is provided with a plurality along the outer side while the air tube 20 is unfolded by the extension of the rod 12 Air is introduced into the one-way valve 30 is made to expand.

이때, 상기 에어튜브(20)의 내측부(21)의 일부는 범퍼(3)나 작동실린더(10)에 고정하고, 그 외측부의 내측단면으로 상기 작동실린더(10)의 로드(12)가 연결되어 에어튜브(20)의 펼치는 작동이 가능하게 된다.In this case, a part of the inner part 21 of the air tube 20 is fixed to the bumper 3 or the working cylinder 10, and the rod 12 of the working cylinder 10 is connected to the inner end of the outer part. Unfolding operation of the air tube 20 is enabled.

또한, 상기 에어튜브(20)는 외측부의 내측단면에 완충재질의 지지횡바(25)를설치하여 상기 작동실린더(10)의 로드(12)를 연결하므로 상기 에어튜브(20)를 횡방향으로 전체적으로 펼치는 작동이 용이하게 된다.In addition, the air tube 20 is installed on the inner end surface of the outer side of the cushioning material supporting bar (25) to connect the rod 12 of the operation cylinder 10, so that the air tube 20 to fully spread in the transverse direction It is easy to operate.

이때, 상기 작동실린더(10)의 로드(12) 선단에는 좌우로 보조지지바(13)를 설치하여 상기 에어튜브(20) 외측부의 내측단면을 미는 작동이 원활하도록 하게 된다.At this time, the auxiliary support bar 13 is installed to the front and rear of the rod 12 of the operation cylinder 10 to smoothly push the inner end surface of the outer portion of the air tube 20.

또한, 본 발명은 상기 작동실린더(10)의 전후방 탄발 유동을 다양한 방법으로실시할 수 있는데, 이는 도 4a,b에 도시된 바와 같이 상기 작동실린더(10)가 삽입되어 안내작동하는 안내로(42)를 갖는 설치브라켓(40)을 설치하되, 상기 안내로(42)에 삽입하거나, 상기 작동실린더(10)와 설치브라켓(40)을 연결하는 형태로 완충스프링(45)(45')을 설치하게 된다.In addition, the present invention can be carried out in various ways to the front and rear shot flow of the operating cylinder 10, which is the guide passage 42 is inserted into the operation cylinder 10 as shown in Figure 4a, b Install the mounting bracket 40 having a), but is inserted into the guide path 42, or installing the buffer spring (45, 45 ') in the form of connecting the operating cylinder 10 and the mounting bracket 40. Done.

미설명부호로서, 22는 작동실린더의 로드(12)를 안내하는 에어튜브(20)의 가이더를 나타내는 것이다.As an unexplained reference numeral 22 denotes a guider of the air tube 20 for guiding the rod 12 of the operation cylinder.

다음은 상기와 같이 구성된 본 발명의 작동 및 작용에 대해 살펴보기로 한다.Next will be described the operation and action of the present invention configured as described above.

즉, 본 발명은 상기 자동차의 전후 범퍼(3)(4) 양측방에 전후방향으로 구멍을 천공하여, 작동실린더(10)를 설치하되, 상기 작동실린더(10)는 차체(5)내부에 고정설치된 설치브라켓(40)에 완충스프링(45)에 의해 전후방향으로 탄발 유동케 안내되도록 설치되고, 상기 작동실린더(10)의 로드(12) 선단에는 절첩된 형태의 에어튜브(20)가 설치된 구조로 되어 있다.That is, according to the present invention, the operation cylinder 10 is installed by drilling holes in the front and rear directions on both sides of the front and rear bumpers 3 and 4 of the vehicle, and the operation cylinder 10 is fixed inside the vehicle body 5. The installation bracket 40 is installed to be guided in the front and rear direction by the shock absorbing spring 45, the structure of the air tube 20 of the folded form is installed at the tip of the rod 12 of the operation cylinder 10 It is.

이와 같은 상태에서 자동차를 사용하게 된다.In this state, the car is used.

이때, 상기 자동차의 전후 범버(3)(4)에는 절첩된 에어튜브(20)만큼만이 돌출된 상태가 되므로, 주행이나 주차시 등에 큰 불편은 없게 된다.At this time, since only the air tube 20 folded into the front and rear bumpers 3 and 4 of the vehicle is in a protruding state, there is no great inconvenience when driving or parking.

이와 같은 상태에서 상기 자동차를 사용하다가 충돌사고가 발생하는 경우, 우선 작은 접촉의 충돌(자동차에 충격을 주지못할 정도)에는 상기 고무재의 절첩된 에어튜브(20) 자체로도 그 충격을 완충함은 물론 차체(5)나 범퍼(3)(4)의 손상을 방지하게 된다.If a collision accident occurs while using the vehicle in such a state, first, the impact of the folded air tube 20 of the rubber material buffers the impact in the event of a small contact collision (not enough to impact the vehicle). Of course, damage to the vehicle body 5 and the bumpers 3 and 4 is prevented.

이와 달리, 큰 충돌사고가 발생하는 경우에, 상기 충돌에 의한 충격을 검지 센서(미도시)가 검지하여 작동실린더(10)를 작동시키게 된다.On the contrary, when a large collision accident occurs, a detection sensor (not shown) detects the impact caused by the collision to operate the operation cylinder 10.

이때, 상기 센서는 차체의 전후부에 설치하여 전후방의 작동실린더(10)가 전후방의 충돌여부에 따라 각각 작동하거나 또는 동시에 작동하도록 설정할 수 있다. 이는 상기 전방부의 충돌과 함께 뒤 따라 오던 차량의 연속충돌이 발생할 소지가 높기 때문이다.In this case, the sensor may be installed at the front and rear of the vehicle body so that the operation cylinders 10 at the front and rear may be set to operate at the same time or at the same time depending on whether the front and rear collisions are performed. This is because there is a high possibility of a continuous collision of the vehicle following the collision with the front part.

이와 같이 작동실린더(10)의 로드(12)가 순간적으로 신장작동하면, 상기 로드선단에 연결된 에어튜브(20) 외측부의 내측단면을 전방으로 밀어 상기 절첩되어 있던 에어튜브(20)를 신장하게 된다.As such, when the rod 12 of the operation cylinder 10 extends momentarily, the inner end surface of the outer portion of the air tube 20 connected to the rod end is pushed forward to extend the folded air tube 20. .

이때, 상기 작동실린더(10)의 로드(12)에는 횡방향으로 연장 형성된 횡바(25)와, 보조지지바(13)에 의해 에어튜브(20)를 폭방향의 전체적으로 일정하게 밀어 전체적으로 펼치는 작동이 원활히 제공된다.At this time, the rod 12 of the operation cylinder 10 has a horizontal bar (25) extending in the lateral direction, the operation of pushing the air tube 20 to the entire width in the width direction by the auxiliary support bar 13 to expand the whole. Provided smoothly.

따라서, 상기 신장되는 에어튜브(20)는 외측면을 따라 형성된 다수의 일방향 밸브(30)를 통해 외부에서 공기가 유입되므로 팽창된 상태가 되기 때문에 상기 충돌에 따른 충격을 통상의 에어백과 같이 완화하게 되는 것이다.Accordingly, the elongated air tube 20 is in an expanded state because air is introduced from the outside through a plurality of one-way valves 30 formed along the outer surface to mitigate the impact of the collision as in a conventional air bag. Will be.

이때, 상기 에어튜브(20)내로 유입된 공기는 상기 일방향 밸브(30)에 의해 다시 외부로 배출되지 않므로 팽팽한 상태를 유지할 수 있어 충격의 완충이 가능하게 된다.At this time, since the air introduced into the air tube 20 is not discharged out again by the one-way valve 30, it is possible to maintain a taut state and to cushion the impact.

더우기, 본 발명은 상기 자동차의 전방 측부에서의 충격이 가해지는 경우에도, 상기 팽창된 에어튜브(20)에 완충작동을 하게 되므로, 결국 자동차의 전후방에 정면이나 측면에서 가해지는 충격에 대해서도 충분히 완충하여 충격을 완화할 수 있는 것이다.In addition, the present invention is a shock absorbing operation to the inflated air tube 20 even when an impact is applied to the front side of the vehicle, and thus fully cushions against an impact applied from the front or side to the front and rear of the vehicle. To mitigate the impact.

또한, 상기 에어튜브(20)를 신장시킨 작동실린더(10)의 로드(12)에 차량의 충격이 직접적으로 작용하는 경우에, 상기 작동실린더(10)는 완충스프링(45)에 탄발적으로 밀리면서 상기 충격에 의한 손상을 방지하게 되는 것이다.In addition, when the impact of the vehicle directly acts on the rod 12 of the operation cylinder 10 in which the air tube 20 is extended, the operation cylinder 10 is elastically pushed against the shock absorbing spring 45. While preventing the damage caused by the impact.
