Description

판스프링을 이용한 자동차용 흡격흡수장치Automobile absorption device using leaf spring

본 고안의 자동차의 전,후측에 장착되는 범퍼의 내부에 설치되는 임펙트빔에 충격 흡수수단을 더 강구한 판스프링을 이용한 자동차 충격흡수장치에 관한 것이다.The present invention relates to an automobile shock absorbing apparatus using a leaf spring further provided with an impact absorbing means in an impact beam installed inside a bumper mounted on a front and a rear of a vehicle of the present invention.

자동차의 범퍼는 자동차의 전,후측에 장착되어 저속충돌시 충격력을 흡수하여 차체를 보호함은 물론 특히 차체의 전방에 위치하고 있는 라디에이터나 헤드라이트 등의 보호함에 그 목적이 있다.The bumper of the vehicle is installed on the front and rear of the vehicle to absorb the impact force at low speed collisions and to protect the vehicle body, as well as to protect the radiator or the headlights located in front of the vehicle body.

종래의 일반적인 자동차의 범퍼는 차체의 프레임선단에 고정되는 임펙트빔, 임펙트빔의 외측에 결합되어 충돌시 충격력을 흡수할 수 있도록 하는 충격흡수재 및 범퍼커버로 구성이 된다.The conventional bumper of the conventional vehicle is composed of an impact beam fixed to the frame front end of the vehicle body, the shock absorber and the bumper cover coupled to the outside of the impact beam to absorb the impact force during a collision.

이러한 종래의 범퍼 경우에는 저속충돌시에도 범퍼자체의 역할을 수행하지 못하고 범퍼커버가 손상되면서 충격흡수재로 전달되는 충력력을 충격흡수재가 원활하게 흡수치 못하게 된다.In the case of such a conventional bumper, the shock absorber does not smoothly absorb the impulse transmitted to the shock absorber as the bumper cover is damaged even when the bumper cover is damaged even at a low speed crash.

이는 충격흡수재가 우레탄과 같은 재질로 되어 있으므로 뾰조한 부위와의 접촉으로 일어나는 충격은 흡수치 못하게 되므로 임펙트빔을 통하여 차체의 전달되어지고, 이 층격력은 다시 좌,우팬더나 헤드라이트 및 라디에이터를 가격하여 차체손상을 크게하는 등의 문제점들이 있었다.Since the shock absorber is made of urethane-like material, the impact caused by contact with the sharp part is not absorbed, so the vehicle body is transmitted through the impact beam. There were problems such as price increase and car body damage.

뿐만 아니라, 충돌후 임펙트빔의 손상내지는 변형을 가져오기 때문에 차체의 손상이 더욱 커지고 복원이 어렵게 되는 등의 문제점들이 있었다.In addition, the damage of the impact beam after the collision is brought about deformation, there is a problem such that the damage of the car body is further increased and difficult to restore.

이에 본 고안에서는 상기한 문제점들을 해결하기 위하여 안출이 된 것으로서 임펙트빔의 전방에 판스프링을 설치하여 충격력을 원활하게 흡수하고 감쇄시킬 수 있도록 한 것이 특징이다.Therefore, the present invention is designed to solve the above problems, it is characterized by the installation of a leaf spring in front of the impact beam to smoothly absorb and attenuate the impact force.

제 1 도는 본 고안의 일 실시예를 도시한 분해 사시도, 제 2 도는 본 고안의 결합상태 단면도로서 함께 설명을 한다.1 is an exploded perspective view showing an embodiment of the present invention, Figure 2 will be described together as a cross-sectional view of the combination of the present invention.

자동차의 차체판넬(어프론;10)에 고정되는 임펙트빔(11)의 전방에 판스프링(12)을 설치하여 저속충돌시 차체로 전하여지는 충격력을 흡수토록 한 것이다.The leaf spring 12 is installed in front of the impact beam 11 fixed to the vehicle body panel (apron) 10 of the vehicle to absorb the impact force transmitted to the vehicle body at low speed collision.

상기 판스프링(12)은 중앙부가 외측으로 돌출되도록 임팩트빔(11)의 양측에 고정볼트(13)를 이용하여 고정을 하되, 상기 판스프링(12)과 고정볼트(13)상간에는 완충작용을 위한 스프링(14)을 개입시키고 고정볼트(13)로 고정되는 부위에는 긴 개구(15)를 형성하여 충돌시 판스프링(12)이 펼쳐지면서 신장할 수 있는 여유를 주었다.The leaf spring 12 is fixed to the both sides of the impact beam 11 by using a fixing bolt 13 so that the center portion protrudes outward, the buffer spring between the plate spring 12 and the fixing bolt 13 has a buffering effect Intervening with the spring (14) for fixing the fixing bolts 13 to form a long opening (15) to give a space to expand the plate spring (12) in the event of a stretch.

상기 판스프링(12)의 내측 중앙과 임펙트빔(11)의 중앙 외측에는 보조판스프링(16,16')를 더 설치하여 충격력 감쇄에 도움이 되도록 하였다.Auxiliary plate springs 16 and 16 'are further installed at the inner center of the leaf spring 12 and the outer center of the impact beam 11 to assist in reducing the impact force.

그리고, 판스프링(12)의 중앙에는 (ㄷ)형상의 래치(20)를 고정하여 충격력 전달시 임펙트빔(11)의 중앙 상면과 저면에는 형성시킨 스트라이커(21)에 결합되어 판스프링(12)이 원복되지 않토록하여 2차충격을 방지토록 한 것이다.In addition, the (L) shaped latch 20 is fixed to the center of the leaf spring 12 so as to be coupled to the striker 21 formed on the upper and lower surfaces of the center of the impact beam 11 when the impact force is transmitted to the leaf spring 12. This prevents secondary shocks.

상기 래치(20)에는 후방에는 선단으로는 경사부(22)를 두고 후방에는 걸림턱(23)을 가지도록 한 로크(24)를 형성하여 스트라이커(21)를 쉽게 벗어나지 않토록 구성한 것이다.The latch 20 has a lock 24 formed at the rear end thereof with an inclined portion 22 at the front end and a locking jaw 23 at the rear thereof so that the striker 21 can be easily removed.

상기와 같이 구성된 본 고안의 작용관계를 살펴보면, 먼저, 판스프링(12)이 설치된 임펙트빔(11)의 외측에 범퍼커버를 씌워서 사용됨은 당연할 것이며, 이러한 상태에서 자동차가 주행중 저속으로 충돌할 경우에 임펙트빔(11)의 전방에 설치된 판스프링(12)에 의하여 충격력이 흡수되는 것이다.Looking at the working relationship of the present invention configured as described above, first, it is natural to use the bumper cover on the outside of the impact beam 11 is installed, the leaf spring 12, in this state, if the car crashes at low speed while driving Impact force is absorbed by the leaf spring 12 installed in front of the impact beam (11).

즉, 1차로 범퍼커버로 충격력이 전달되면 그 여파가 임펙트빔(11)의 전방에 돌출되게 설치된 판스프링(12)에 충격력이 전달되어진다.That is, when the impact force is first transmitted to the bumper cover, the impact force is transmitted to the leaf spring 12 installed to protrude in front of the impact beam 11.

충격력을 전달받은 판스프링(12)은 충격력에 의하여 측방으로 펼쳐지면서 임펙트빔(11)방향으로 밀착되면서 충격력을 흡수/감쇄시키는 것이다.The plate spring 12 received the impact force is absorbed / attenuated by the impact force while being in close contact with the impact beam 11 while being extended laterally by the impact force.

이는 판스프링(12)의 양측에 긴 개구(15)를 형성하고있고 이 개구(15)에 스프링(14)을 개입시킨체 고정볼트(13)로 고정되어 있으므로 충격력을 전달받은 판스프링(12)은 개구(15)의 폭만큼 펼쳐지면서 1차충격을 흡수하고 다시 임펙트빔(11)방향으로 밀착되면서 보조판스프링(16,16')와 스프링(14)에 의하여 2차로 충격을 흡수하게 되는 것이다.It forms a long opening (15) on both sides of the leaf spring (12) and is fixed to the fixing bolt 13 through the spring 14 through the opening (15), the leaf spring received the impact force (12) Is absorbed by the width of the opening 15 to absorb the primary shock and again in the direction of the impact beam 11 is to absorb the secondary shock by the auxiliary plate spring (16, 16 ') and the spring (14).

그리고, 판스프링(12)이 임펙트빔(11)과 연접함과 동시에 판스프링(12)의 중앙에 고정한 래치(20)의 걸림턱(23)이 임펙트빔(11)의 중앙 상면과 저면에 형성된 스트라이커(21)에 걸림이 됨으로서 판스프링(12)이 원복치 못하게하여 충돌후 발생하는 2차 충격의 발생을 억제하게 되는 것이다.In addition, while the leaf spring 12 is in contact with the impact beam 11, the latching jaw 23 of the latch 20 fixed to the center of the leaf spring 12 is formed on the top and bottom surfaces of the center of the impact beam 11. By being caught by the striker 21, the leaf spring 12 is not restrained, thereby suppressing the occurrence of the secondary shock occurring after the collision.

상기 래치(20)와 스트라이커(21)의 결합상태는 인위적인 방법으로 강제 해지를 시켜재 사용할 수 있게되는 것이다.Coupling state of the latch 20 and the striker 21 is to be reusable by artificially forced release.

제 3 도는 본 고안의 다른 실시예를 도시한 단면도로서 도어임펙트빔을 판스프링(12)으로 대체한 것이다.3 is a cross-sectional view showing another embodiment of the present invention to replace the door impact beam with a leaf spring (12).

즉, 판스프링(12)의 양단부에는 고정공(51)을 형성하여 고정볼트(52)로서 도어(53)의 양측방 프레임(54)상에 고정하고, 도어외부판넬(55)과 연접하는 면의 판스프링(12)부위에는 충격완화와 더불어 판스프링(12)의 유동을 방지할 수 있도록 고무나 실리콘(60)으로 마감을 하여 측면 충격력을 흡수토록 한 것이다.That is, the surface of the leaf spring 12 is formed with a fixing hole 51 to be fixed on both sides of the frame 54 of the door 53 as a fixing bolt 52, the surface that is in contact with the outer panel 55 The leaf spring portion 12 of the rubber or silicon (60) to prevent the flow of the leaf spring 12 with the impact mitigation is to absorb the side impact force.

이상과 같은 본 고안은 임펙트빔의 전방에 부착된 판스프링에 의하여 충격력을 감쇄시킴은 물론 임펙트빔의 변형을 방지하여 차체손상은 물론 임명피해도 줄일 수 있는 등의 장점을 가진다.The present invention as described above has the advantage of reducing the impact force by the leaf spring attached to the front of the impact beam, as well as preventing deformation of the impact beam to reduce the damage to the body as well as installation.
