본 발명은 영구자석과 전자석을 통한 완충장치가 설치된 차량용 범퍼에 관한 것으로, 더욱 상세하게는 범퍼페이스의 내면과 차체 전면의 사이에 차례대로 설치된 제1영구자석과 제2영구자석 간의 척력과 함께 상기 제2영구자석의 후방에 설치되어 차량의 주행속도 60km/h이상과 충돌체와 거리 6~8m이내일 때 작동하는 전자석의 척력을 통해 다른 차량 혹은 장애물과의 충돌시 발생하는 충격을 차량의 주행속도 60km/h를 기준으로 하여 적응적인 완충력으로 효과적으로 흡수 완충하는 구조를 제공함에 따라, 보다 우수하고 향상된 충격 흡수 기능을 발휘하게 됨으로써, 차량의 파손과 함께 승차자의 부상을 방지하여 물적 및 인적 피해를 최소화할 수 있도록 한 영구자석과 전자석을 통한 완충장치가 설치된 차량용 범퍼에 관한 것이다. The present invention relates to a bumper for a vehicle provided with a permanent device and a shock absorber through an electromagnet, and more particularly, with the repulsive force between the first permanent magnet and the second permanent magnet, which are sequentially installed between the inner surface of the bumper face and the front of the vehicle body. It is installed at the rear of the second permanent magnet, and the shock generated by collision with other vehicles or obstacles through the repulsive force of the electromagnet operated when the vehicle's traveling speed is more than 60km / h and the collision body is within 6-8m. By providing a structure that absorbs and absorbs effectively with an adaptive buffering force based on 60 km / h, it exhibits better and improved shock absorption function, thereby minimizing physical and human damage by preventing vehicle injuries and injury to passengers.

[문헌 1] 한국 공개특허공보 제10-2002-0074885호, 2002.10.04.[Document 1] Korean Unexamined Patent Publication No. 10-2002-0074885, 2002.10.04.

일반적으로 차량이 다른 차량 혹은 그 밖에 장애물 등과 충돌할 경우, 차량의 전면과 후면에 설치되어 있고 범퍼페이스와 충격흡수폼으로 크게 구성된 범퍼가 충돌시 발생하는 충격을 흡수 완충하는 기능을 수행함에 따라 차체의 큰 손상을 방지함과 아울러 승차자의 크고 작은 부상을 예방할 수 있도록 한다. In general, when a vehicle collides with another vehicle or other obstacles, the bumper is installed on the front and rear of the vehicle and a bumper face composed of a bumper face and a shock absorbing foam absorbs and cushions the shock generated during the collision. This prevents major damage to the passengers and prevents injuries of passengers, large and small.

즉, 범퍼페이스가 충격에 의해 차체 측으로 밀리고 충격흡수폼이 범퍼페이스와 차체의 사이에서 압축되면서 충격을 흡수 완충하여 상기의 효과를 달성하는 것이다. That is, the bumper face is pushed toward the vehicle body by the impact and the shock absorbing foam is compressed between the bumper face and the vehicle body to absorb and cushion the shock to achieve the above effect.

그러나 이러한 차량의 범퍼는 차량의 주행속도가 저속에서 충돌할 경우에는 제기능을 충분히 할 수 있지만 차량의 주행속도가 30~40Km/h 이상에서 충돌할 경우에는 충격흡수폼의 완충 능력에 한계가 있으므로 범퍼페이스와 충격흡수폼이 쉽게 파손되어 상기한 기능을 제대로 발휘할 수 없는 문제점이 있었다. However, the bumper of such a vehicle can function properly when the traveling speed of the vehicle collides at a low speed, but the shock absorbing foam cushioning ability is limited when the traveling speed of the vehicle collides at 30-40 km / h or more. There was a problem that the bumper face and the shock absorbing foam are easily broken so that the above functions cannot be properly exhibited.

이러한 문제점을 해소하기 위하여 범퍼의 내부에 동일한 극성을 가지는 두 개의 영구자석을 일정공간을 사이에 두고 설치한 자기력을 이용한 차량용 범퍼가 선출되었다. 즉, 동일한 극성을 가짐에 따라 서로 밀어내는 척력을 이용하여 범퍼로 가해지는 충격을 흡수 완충하는 것이다. In order to solve such a problem, a bumper for a vehicle using a magnetic force installed with two permanent magnets having the same polarity in a predetermined space therebetween was selected. That is, the shock applied to the bumper is absorbed and buffered by using the repulsive force pushing each other with the same polarity.

따라서 차량의 주행속도가 30~40Km/h 이상에서 충돌할 경우에 범퍼페이스와 충격흡수폼의 완충 능력에 상기 영구자석 간의 척력에 의한 완충 능력이 더해지게 됨에 따라, 범퍼페이스가 파손되면서 충격흡수폼을 타격하여 상기 충격흡수폼이 차체 측으로 압축되더라도 파손되지 않고 다시 원상태로 복귀할 수 있게 됨으로써 그 충격을 효과적으로 흡수 완충할 수 있었다. Therefore, when the vehicle travels at a speed of 30-40 km / h or more, the shock absorbing ability of the bumper face and the shock absorbing foam is added to the cushioning ability of the permanent magnet by the repulsive force between the permanent magnets. By hitting the shock absorbing foam can be restored to its original state without being damaged even if the shock absorbing foam is compressed to the vehicle body side was able to absorb and buffer the shock effectively.

그러나 상기한 자기력을 이용한 차량용 범퍼도 일정한 척력을 발휘하는 두 영구자석에 의해 충격을 흡수 완충하는 구조임에 따라, 차량의 주행속도가 60km/h 이상에서 충돌할 경우에는 영구자석의 척력도 감당할 수 없는 매우 큰 충격이 발생되므로, 범퍼페이스와 충격흡수폼이 그대로 파손되고, 이로 인해 차체가 크게 파손되게 되며 승차자도 크게 부상을 입게 되는 문제점을 여전히 가지고 있다. However, the vehicle bumper using the magnetic force is also a structure that absorbs and cushions the shock by the two permanent magnets exhibiting a certain repulsive force, so when the vehicle's traveling speed collides more than 60km / h, the permanent magnet can also handle the repulsive force Since a very large impact is not generated, the bumper face and the shock absorbing foam are damaged as it is, and thus the vehicle body is greatly damaged, and the passenger still suffers a serious injury.

본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 차량의 주행속도에 관계 없이 범퍼의 정면으로 가해지는 충격을 효과적으로 완충하여 차량의 손상을 막고 승차자의 부상도 방지할 수 있도록 하기 위하여, 동일한 극성을 가지는 두 개의 영구자석 간에 작용하는 척력을 이용하여 충돌로 인한 충격을 흡수 완충하는 차량용 범퍼를 구성함에 있어서, 범퍼페이스의 내면에 설치된 제1영구자석과; 차체의 전면에 설치된 충격흡수폼의 전면에 설치되어 상기 제1영구자석과 동일한 극성을 가지는 제2영구자석과; 상기 충격흡수폼의 내부에 설치되어 차량의 주행속도가 기준속도 이상시 상기 제2영구자석과 동일한 극성을 가지는 전자석을; 포함하여 구성됨을 특징으로 한 영구자석과 전자석을 이용한 완충장치가 설치된 차량용 범퍼를 제공함에 그 목적이 있다. The present invention has been invented to solve the above problems, in order to effectively cushion the impact applied to the front of the bumper regardless of the running speed of the vehicle to prevent damage to the vehicle and to prevent injuries of the rider, In constructing a vehicle bumper for absorbing and cushioning a shock caused by a collision by using a repulsive force acting between two permanent magnets having a polarity, the first permanent magnet installed on the inner surface of the bumper face; A second permanent magnet installed at the front of the shock absorbing foam installed at the front of the vehicle body and having the same polarity as the first permanent magnet; An electromagnet installed inside the shock absorbing foam and having the same polarity as the second permanent magnet when the traveling speed of the vehicle is equal to or greater than the reference speed; An object of the present invention is to provide a bumper for a vehicle in which a shock absorber using a permanent magnet and an electromagnet is installed.

본 발명은 기준속도를 기준으로 차량의 주행속도에 따라 범퍼를 보강하는 척력을 다르게 작용시켜 범퍼로 가해지는 충격을 지능적이면서 효과적으로 흡수 완충함으로써 차체의 파손은 물론이고 승차자의 부상을 방지하여 인적피해 및 물적피해를 최소화할 수 있는 효과가 있다. The present invention intelligently and effectively absorbs and cushions the shock applied to the bumper by differently applying the repulsive force to reinforce the bumper according to the traveling speed of the vehicle based on the reference speed, thereby preventing damage to the vehicle body and injury to the occupant. There is an effect that can minimize physical damage.

상기 범퍼페이스(1)는 차체(3)의 양측에 형성된 유동공간(9)에 의해 충격시 후방으로 밀려날 수 있도록 차체(3)에 설치되어 있다. The bumper face 1 is provided on the vehicle body 3 so that the bumper face 1 can be pushed backward in the event of an impact by the flow spaces 9 formed on both sides of the vehicle body 3.

상기 제1영구자석(2)은 제2영구자석(5) 간의 척력이 방해 받지 않도록 고무판(10)을 매개로 범퍼페이스(1)의 내면에 설치되어 있다. The first permanent magnet 2 is provided on the inner surface of the bumper face 1 via the rubber plate 10 so that the repulsive force between the second permanent magnets 5 is not disturbed.

이와 같이 구성된 본 발명의 영구자석과 전자석을 이용한 완충장치가 설치된 차량용 범퍼(100)는 차량의 차체(3) 정면 및 후면에 설치되어 다른 차량 혹은 장애물 등과의 충돌시 가해지는 충격을 흡수 완충하여 차체(3)의 손상과 승차자의 부상 을 방지하기 위한 보호장치이다. The bumper 100 for a vehicle in which the shock absorber using the permanent magnet and the electromagnet of the present invention configured as described above is installed on the front and rear of the vehicle body 3 so as to absorb and cushion the impact applied when colliding with another vehicle or an obstacle. (3) It is a protective device to prevent the damage and injury of the occupant.

특히, 본 발명의 영구자석과 전자석을 이용한 완충장치가 설치된 차량용 범퍼(100)는 차량의 주행속도에 관계 없이 우수한 완충 능력을 발휘함에 따라 더욱 효과적으로 완충 기능을 할 수 있는 것이 큰 특징이다. Particularly, the bumper 100 for a vehicle in which the shock absorber using the permanent magnet and the electromagnet of the present invention is installed is characterized in that the shock absorbing function can be more effectively performed as it exhibits excellent shock absorbing ability regardless of the running speed of the vehicle.

이는 도 1과 도 2에 도시된 바와 같이, 범퍼페이스(1)의 내면에 제1영구자석(2)이 설치되고, 차체(3)의 전면에 설치된 충격흡수폼(4)의 전면에 상기 제1영구자석(2)과 동일한 극성을 가지는 제2영구자석(5)이 설치되며, 상기 충격흡수폼(4)의 내부에 차량의 주행속도가 기준속도 이상일 때 작동하여 상기 제2영구자석(5)과 동일한 극성을 가지는 전자석(6)이 설치됨에 의한 것이다. 1 and 2, the first permanent magnet 2 is installed on the inner surface of the bumper face 1, and the first permanent magnet 2 is installed on the front surface of the shock absorbing foam 4 installed on the front of the vehicle body 3. The second permanent magnet 5 having the same polarity as that of the first permanent magnet 2 is installed, and operates when the traveling speed of the vehicle is greater than or equal to the reference speed in the shock absorbing foam 4. This is because the electromagnet 6 having the same polarity as) is installed.

즉, 차량의 주행속도에 따라 범퍼페이스(1)와 충격흡수폼(4) 간의 척력작용공간(13)에 자력에 의한 척력의 크기를 적응적으로 다르게 적용시켜 효과적으로 완충 기능을 할 수 있게 한 것에 의한 것이다. 이의 작용을 상세하게 설명하면 다음과 같다. That is, by applying the magnitude of the repulsive force by the magnetic force adaptively differently in the repulsive action space 13 between the bumper face 1 and the shock absorbing foam (4) according to the running speed of the vehicle to effectively buffer Is due. The operation thereof is described in detail as follows.

먼저, 차량의 주행속도가 60km/h 미만으로 주행할 경우에는 충격흡수폼(4)의 내부에 설치된 전자석(6)이 작동하는 기준속도 보다 느린 속도이므로, 범퍼페이스(1)의 내면에 설치된 제1영구자석(2)과 충격흡수폼(4)의 전면에 설치된 제2영구자석(5) 간의 척력이 작용한다. First, when the traveling speed of the vehicle is less than 60km / h, since the electromagnet 6 installed inside the shock absorbing foam 4 is slower than the reference speed at which the vehicle operates, the vehicle is installed on the inner surface of the bumper face 1. The repulsive force between the first permanent magnet 2 and the second permanent magnet 5 installed on the front surface of the shock absorbing foam 4 acts.

따라서 60km/h 미만의 주행속도에서 다른 차량이나 장애물 등과 충돌할 경우 상기 제1영구자석(2)과 제2영구자석(5) 간에 작용하는 척력이 척력작용공간(13) 내부에 작용하여 완충력을 보강하게 됨으로써, 상기 범퍼페이스(1)가 차체(3) 측으로 밀리더라도 파손될 정도로 밀리지 않아 충격을 효과적으로 흡수 완충할 수 있게 된다. Therefore, when colliding with another vehicle or obstacle at a traveling speed of less than 60 km / h, the repulsive force acting between the first permanent magnet 2 and the second permanent magnet 5 acts inside the repulsive action space 13 to provide a buffering force. By reinforcing, even if the bumper face 1 is pushed toward the vehicle body 3 side, the bumper face 1 is not pushed to the extent of being damaged, so that the shock can be effectively absorbed and buffered.

더욱이 상기 범퍼페이스(1)는 차체(3)에 형성된 유동공간(9)에 의해 후방으로 밀려나게 설치되어 있기 때문에 전혀 파손 없이 후방으로 밀려나게 된다. Furthermore, since the bumper face 1 is installed to be pushed backward by the flow space 9 formed in the vehicle body 3, it is pushed backward without any damage.

또한, 상기 범퍼페이스(1)는 상기 원상태로 제1영구자석(2)과 제2영구자석(5) 간에 작용하는 척력으로 인해 바로 원상태로 복원됨에 따라 2차적인 충돌로 인한 충격도 효과적으로 흡수 완충할 수 있게 된다. In addition, since the bumper face 1 is restored to its original state due to the repulsive force acting between the first permanent magnet 2 and the second permanent magnet 5 in the original state, the shock caused by the secondary collision is also effectively absorbed and buffered. You can do it.

이에 따라 범퍼페이스(1)의 파손을 방지함과 동시에 차체(3)의 파손도 방지할 수 있게 된다. Accordingly, damage to the bumper face 1 can be prevented and damage to the vehicle body 3 can be prevented.

여기서 제1영구자석(2)의 전면에 부착되어 제1영구자석(2)의 자력이 척력작용공간(13) 측으로만 작용되게 하는 고무판(10)과, 충격흡수폼(4)의 내부에 수직으로 설치되어 제2영구자석(5)을 후면에서 지지하여 제2영구자석(5)이 제1영구자석(2)과의 척력에 의해 차체(3) 측으로 밀리는 것을 막는 보강대(7)에 의해 척력작용공간(13)에서의 제1영구자석(2)과 제2영구자석(5) 간의 척력이 더욱 효과적으로 작용할 수 있게 된다. Here, the rubber plate 10 is attached to the front surface of the first permanent magnet 2 so that the magnetic force of the first permanent magnet 2 is applied only to the repulsive action space 13 side, and perpendicular to the interior of the shock absorbing foam 4. The second permanent magnet (5) from the rear to support the second permanent magnet (5) by the reinforcement (7) to prevent the second permanent magnet (5) from being pushed to the vehicle body 3 side by the repulsive force with the first permanent magnet (2) The repulsive force between the first permanent magnet 2 and the second permanent magnet 5 in the working space 13 can act more effectively.

그리고 차량의 주행속도가 60km/h 이상으로 주행하면서 충돌체와의 거리가 6~8mm 이내일 경우에는 전자석(6)이 작동하는 기준속도와 기준거리에 동시에 만족하므로, 제1영구자석(2) 및 제2영구자석(5)과 함께 전자석(6)이 컨트롤박스(12)에 의해 작동하게 된다. And when the traveling speed of the vehicle is more than 60km / h and the distance to the colliding body is within 6 ~ 8mm, the first permanent magnet (2) and The electromagnet 6 is operated by the control box 12 together with the second permanent magnet 5.

따라서 60km/h 미만의 주행속도에서 다른 차량이나 장애물 등과 충돌할 경우 척력작용공간(13) 내부에는 제1영구자석(2)과 제2영구자석(5) 간에 작용하는 척력에다가 전자석(6)이 더해진 척력이 작용하여 범퍼(100)의 완충력을 더욱 보강하게 된다. Therefore, when colliding with another vehicle or obstacle at a traveling speed of less than 60 km / h, the electromagnet 6 is added to the repulsive force acting between the first permanent magnet 2 and the second permanent magnet 5 in the repulsive action space 13. The added repulsive force acts to further reinforce the buffering force of the bumper 100.

이에 따라 상기보다 더 큰 충격이 범퍼페이스(1)로 가해지라도 범퍼페이스(1)는 파손될 정도로 밀리지 않고 버텨 본래의 위치로 복귀됨으로써 범퍼페이스(1)와 차체(3)의 파손 없이 상기 충격을 효과적으로 흡수 완충할 수 있게 된다. 이를 통해 차량에 승차한 승차자의 안전도 보장할 수 있게 된다. Accordingly, even if a larger impact is applied to the bumper face 1, the bumper face 1 is not pushed to the extent of being damaged and returned to its original position so that the impact is effectively prevented without damaging the bumper face 1 and the vehicle body 3. Absorption buffer becomes possible. Through this, it is possible to ensure the safety of the rider riding on the vehicle.

상기와 같이 본 발명의 영구자석과 전자석을 이용한 완충장치가 설치된 차량용 범퍼(100)는 기준속도를 기준으로 차량의 주행속도에 따라 범퍼(100)를 보강하는 척력을 다르게 작용시켜 지능적으로 범퍼(100)로 가해지는 충격을 흡수 완충할 수 있게 됨으로써, 차체(3)의 파손은 물론이고 승차자의 부상을 방지하여 인적 및 물적 피해를 최소화할 수 있게 된다. As described above, the bumper 100 for a vehicle in which the shock absorber using the permanent magnet and the electromagnet of the present invention is installed has a bumper 100 intelligently by acting different repulsive forces to reinforce the bumper 100 according to the traveling speed of the vehicle based on the reference speed.
