Abstract

PURPOSE: A vehicle bumper using a magnetic force is provided to enhance a passenger's safety without increasing a thickness of the bumper by arranging magnetic plates of a same polarity to face each other. CONSTITUTION: A bumper is composed of a front bumper(11), an energy absorbing plate(12) and a reinforcing plate(13). The energy absorbing plate(12) and the reinforcing plate(13) including each magnet(10a,10b) are separated from each other in a certain distance. Same polarity of the magnets(10a,10b) are arranged to face each other, so that a repulsive force generates if the magnets come close each other. The reinforcing plate is placed between the energy absorbing plate and a vehicle body(14). An elastic assembly(15) for increasing a shock absorbing effect by the repulsive force of the magnets(10a,10b) is installed between the vehicle body(14) and the reinforcing plate. The elastic assembly is composed of a coil spring(15c), a spring inserting pipe(15a), and a rod(15b).

Description

자기력을 이용한 차량 범퍼{A bumper using magnetic force for automobile}A bumper using magnetic force for automobile}

본 발명은 차량의 범퍼에 관한 것으로, 상세하게는 같은 극으로 마주하는 자석판이 제공된 차량의 범퍼에 관한 것이다.The present invention relates to a bumper of a vehicle, and more particularly to a bumper of a vehicle provided with magnetic plates facing the same pole.

자동차가 장애물과 충돌할 경우, 범퍼는 충격을 흡수하여 차체와 탑승객을 부상으로부터 보호하도록 차량의 전면과 후면에 설치된다.If the vehicle collides with an obstacle, bumpers are installed on the front and rear of the vehicle to absorb shocks and protect the body and passengers from injury.

도 2는 차량 전면에 제공된 범퍼의 구성이 도시된 것으로, 범퍼는 범퍼 페이스(1), 에너지 흡수 폼(2), 보강판(3)으로 구성된다. 범퍼 페이스(1)는 차량의 외측면에 위치되고, 보강판(3)은 범퍼 페이스(1)의 내측에 위치된다. 또한, 에너지 흡수 폼(2)은 범퍼 페이스(1)와 보강판(3) 사이에 있고 일반적으로 발포성 플라스틱으로 형성된다.2 shows the configuration of a bumper provided on the front of the vehicle, which is composed of a bumper face 1, an energy absorbing foam 2 and a reinforcement plate 3. The bumper face 1 is located on the outer side of the vehicle and the reinforcement plate 3 is located inside the bumper face 1. In addition, the energy absorbing foam 2 is between the bumper face 1 and the reinforcement plate 3 and is generally formed of foamable plastic.

상기 구성에 의하여, 차량이 장애물과 충돌하게 되면 범퍼 페이스(1)는 차량 안쪽으로 밀리며, 에너지 흡수 폼(2)은 범퍼 페이스(1)와 보강판(3) 사이에서 압축되면서, 충격을 흡수하여 차체를 보호한다.By the above configuration, when the vehicle collides with an obstacle, the bumper face 1 is pushed into the vehicle, and the energy absorbing foam 2 is compressed between the bumper face 1 and the reinforcement plate 3 to absorb shocks. Protect the bodywork

그러나, 상기된 바와 같은 구성을 가지는 범퍼는 차량이 강하게 충돌할 경우 에너지 흡수 폼이 충격에 의하여 짓눌려 파손되고, 재충돌할 경우 파손된 에너지 흡수 폼은 충격을 효과적으로 흡수하지 못하며, 범퍼의 완충력을 향상시키려면 에너지 흡수 폼의 부피가 커져야하므로 차량의 외관미가 나빠지는 단점이 있었다.However, the bumper having the configuration as described above is damaged by the energy absorbing foam is crushed by the impact when the vehicle is strongly impacted, the broken energy absorbing foam does not effectively absorb the impact when the collision, and improves the buffering capacity of the bumper In order to increase the volume of the energy-absorbing foam has a disadvantage that the appearance of the vehicle worsens.

따라서, 차량이 재충돌할 경우에도 완충효과가 감소되지 않도록 자석의 척력을 이용하여 완충 효과를 향상시키는데 목적이 있다.Therefore, an object of the present invention is to improve the shock absorbing effect by using the repulsive force of the magnet so that the shock absorbing effect is not reduced even when the vehicle crashes again.

도 1은 본 발명에 따른 차량 범퍼의 구성이 도시된 사시도.1 is a perspective view showing the configuration of a vehicle bumper according to the present invention.

도 2는 종래의 차량 범퍼의 구성이 도시된 사시도.Figure 2 is a perspective view showing the configuration of a conventional vehicle bumper.

본 발명은 차량 전면에 위치되는 범퍼 페이스와, 범퍼 페이스의 내측면에 위치되며 자석판이 제공된 에너지 흡수 판과, 상기 자석판과 서로 마주하는 자석판을 포함하며 에너지 흡수 판으로부터 일정 거리 이격되며 수 개의 개구부가 제공된 보강판과, 에너지 흡수 판과 차체를 가압하도록 개구부를 관통하여 양단이 에너지 흡수 판과 차체에 고정되며 탄성을 가지는 탄성 조립체로 구성된다.The present invention includes a bumper face positioned at the front of the vehicle, an energy absorbing plate positioned on the inner side of the bumper face and provided with a magnet plate, and a magnet plate facing each other with the magnet plate and spaced apart from the energy absorbing plate by a certain distance, and having several openings. A reinforcing plate provided, and an elastic assembly having elasticity, both ends being fixed to the energy absorbing plate and the vehicle body through the opening to pressurize the energy absorbing plate and the vehicle body.

이하, 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the drawings.

도 1에 도시된 바와 같이, 범퍼는 프론트 범퍼(11), 에너지 흡수판(12), 보강판(13)으로 구성된다. 서로 일정 거리 이격되어 설치된 에너지 흡수 판(12)과 보강판(13)은 각각 자석들(10a, 10b)이 서로 마주하여 제공된다. 자석들(10a, 10b)은 근접할 경우 척력을 갖도록 서로 같은 극으로 배열되며, 충격에 의하여 파손되지 않도록 고무 재질로 형성되는 것이 바람직하다.As shown in FIG. 1, the bumper includes a front bumper 11, an energy absorbing plate 12, and a reinforcing plate 13. The energy absorbing plate 12 and the reinforcing plate 13 provided to be spaced apart from each other by a distance are provided with the magnets 10a and 10b facing each other. The magnets 10a and 10b are arranged at the same poles so as to have repulsion when they are close, and are preferably formed of a rubber material so as not to be damaged by an impact.

또한, 자석(10a, 10b)은, 도면에 도시된 바와 같이, 에너지 흡수 판(12) 및 보강판(13)에 부착되는 작은 크기로 형성될 수도 있고, 에너지 흡수 판(12)과 보강판(13)의 전면 또는 후면 크기로 부착될 수도 있다. 보강판(13)은 에너지 흡수 판(12)과 차체(14)사이에 위치되며 수 개의 개구부(13a)가 제공된다.In addition, the magnets 10a and 10b may be formed in a small size attached to the energy absorbing plate 12 and the reinforcing plate 13 as shown in the drawing, and the energy absorbing plate 12 and the reinforcing plate ( It may be attached to the front or rear size of 13). The reinforcement plate 13 is located between the energy absorbing plate 12 and the vehicle body 14 and is provided with several openings 13a.

자석들(10a, 10b)의 척력에 의한 완충 효과를 증가시키도록 탄성 조립체(15)가 차체(14)와 보강판(13) 사이에 설치된다. 탄성 조립체(15)는 코일 스프링(15c)과, 일단부가 차체에 고정되며 스프링(15c)이 삽입된 스프링 삽입관(15a)과, 스프링 삽입관(15a)에 삽입되며 일단부가 보강판(13)에 고정되는 봉(15b)으로 구성된다. 또한, 탄성 조립체(15)는 에너지 흡수 판(12)과 차체(14)를 탄성적으로 가압하도록 일단부가 차체(14)에 고정되며 타단부가 보강판(13)을 관통하여 에너지 흡수 판(12)에 고정된다.An elastic assembly 15 is installed between the vehicle body 14 and the reinforcement plate 13 to increase the shock absorbing effect by the repulsive forces of the magnets 10a and 10b. The elastic assembly 15 includes a coil spring 15c, a spring insertion tube 15a having one end fixed to the vehicle body and having a spring 15c inserted therein, and a spring insertion tube 15a inserted at one end thereof and having a reinforcing plate 13. It consists of a rod (15b) fixed to. In addition, the elastic assembly 15 has one end fixed to the vehicle body 14 to elastically pressurize the energy absorbing plate 12 and the vehicle body 14, and the other end penetrates the reinforcing plate 13 to allow the energy absorbing plate 12 to be elastically pressed. It is fixed to).

상기 구성에 의하여, 차량 충돌시 에너지 흡수 판(12)이 보강판(13) 측으로 밀릴 경우, 개구부(15)을 관통하는 탄성 조립체(15)는 충격에너지를 차체에 전달하면서 압축되고, 에너지 흡수 판(12)과 보강판(13)의 거리는 탄성체(15)가 일정 정도 압축된 후에 좁혀지며 거리가 좁혀질수록 자석판(10a, 10b)에 의한 척력은 증가한다.According to the above configuration, when the energy absorbing plate 12 is pushed toward the reinforcing plate 13 during a vehicle collision, the elastic assembly 15 penetrating through the opening 15 is compressed while transmitting impact energy to the vehicle body, and the energy absorbing plate The distance between the 12 and the reinforcing plate 13 is narrowed after the elastic body 15 is compressed to some extent, and the repulsive force by the magnetic plates 10a and 10b increases as the distance is narrowed.

그러나, 탄성 조립체(15)는 차체(14)와 보강판(13)사이에 제공되었지만, 범퍼 페이스(11)와 차체(14) 사이에 제공되어도 동일한 효과를 얻을 수 있고, 자석판(10a, 10b)은 범퍼 페이스(11)와 에너지 흡수판(12)에 같은 극으로 서로 마주하여 제공될 수도 있다.However, although the elastic assembly 15 is provided between the vehicle body 14 and the reinforcement plate 13, the same effect can be obtained even if provided between the bumper face 11 and the vehicle body 14, and the magnetic plates 10a and 10b. The silver may be provided to the bumper face 11 and the energy absorbing plate 12 facing each other at the same pole.

이에 의하여, 범퍼의 완충 효과를 개선하는 것은 자석판의 자기력을 증가시키는 것으로 용이하게 달성되므로 범퍼의 두께가 늘어나지 않고, 완충 효과는 서로 떨어져 있는 자석판에 의하여 달성되므로 에너지 흡수 판이 짓눌려 파손되지 않아 차량이 재충돌할 경우에도 완충 효과가 감소되지 않는 효과가 있다.As a result, improving the shock absorbing effect of the bumper is easily achieved by increasing the magnetic force of the magnetic plate, so that the thickness of the bumper does not increase, and the shock absorbing effect is achieved by the magnetic plates that are separated from each other. In the event of a collision, the buffering effect is not reduced.
