Description
본 고안은 차량용 범퍼에 관한 것으로서, 특히 차량 충돌시 완충 구조물을 이용하여 그 충격을 흡수하는 충격완화용 범퍼 구조물(bumper structure for relieving an impact for automobile)에 관한 것이다.The present invention relates to a bumper for a vehicle, and more particularly, to a bumper structure for relieving an impact for automobile, which absorbs the shock by using a shock absorbing structure in a vehicle collision.
일반적으로, 범퍼는 차량의 앞뒤에서 보디를 보호하기 위하여 설치되는 구조물로서, 충돌시 그 충격을 흡수하도록 사용된다. 종래에는 강철 재료를 이용하여 보디에서 약간 튀어나온 정도였으나 미국에서 대형 범퍼가 사용되게 되어 오늘날에는 에너지 흡수 범퍼라고 불리우는 것이 일반화되어 있다. 이러한 범퍼는 강철 비임과 커버의 사이에 업소버(absorber)와 같은 충격흡수재가 개지되는 구조를 취하고 있고, 충격 흡수재로는 우레탄 등이 사용된다.In general, the bumper is a structure installed to protect the body in front and behind the vehicle, and is used to absorb the impact in a collision. Conventionally, it was a bit protruding from the body using a steel material, but large bumpers are used in the United States, and it is now commonly called an energy absorbing bumper. This bumper has a structure in which a shock absorber such as an absorber is sandwiched between the steel beam and the cover, and urethane or the like is used as the shock absorber.
최근들어서는, 상기와 같은 복잡한 구조를 취하는 범퍼를 대신하여 강성유지 및 충격흡수의 양 기능을 동시에 수행하게 되는 백빔(back beam)이 널리 사용되고 있으며, 도 1에는 종래 기술에 따라 장착된 차량의 개략적인 사시도이고, 도 2는 도 1의 선 A-A를 따라 취한 단면도이다.Recently, a back beam that performs both functions of rigid maintenance and shock absorption is widely used in place of a bumper having such a complicated structure, and FIG. 1 schematically shows a vehicle mounted according to the prior art. 2 is a perspective view, taken along line AA of FIG. 1.
프런트 범퍼(10)는 차량의 전단부에서 전방으로 돌출하여 설치되는데, 도 2에서 처럼, 하나의 패널로 형성된 범퍼 커버(12)가 최전방을 보호하도록 감싸서 장착된다.The front bumper 10 is installed to protrude forward from the front end of the vehicle. As shown in FIG. 2, the bumper cover 12 formed of one panel is wrapped and installed to protect the foremost front.
그러나, 상기한 바와 같이 구조되는 종래 기술에 따른 범퍼 구조에 있어서는, 충격 시험을 수행하거나 외부물체와 충돌할 경우, 범퍼에 의해 1차충격 흡수기능만 수행하기 때문에 외부로 받은 충격에너지를 충분히 분산 또는 흡수시키지 못해 범퍼에 크랙이 발생되고 충격 완화성능이 저하되는 문제점이 있었다.However, in the bumper structure according to the prior art structured as described above, when the impact test is performed or collides with an external object, only the primary shock absorption function is performed by the bumper, so that the impact energy received from the outside is sufficiently dispersed or There was a problem in that the bumper is not absorbed and the shock absorbing performance is reduced.
본 고안은 상기한 바와 같은 종래 기술에 내재되었던 문제점을 해결하기 위해 창안된 것으로서, 본 고안의 목적은 범퍼의 내측에 충격완화 구조물을 설치하여 충격력을 흡수 및 분산시키게 하므로써 충격 완화성능을 향상시킬 수 있는 충격 완화용 범퍼 구조물을 제공함에 있다.The present invention was devised to solve the problems inherent in the prior art as described above, an object of the present invention is to install a shock-absorbing structure inside the bumper to absorb and disperse the impact force, thereby improving the shock-absorbing performance. The present invention provides a shock absorbing bumper structure.

도 2는 도 1의 선 A-A를 따라 취한 단면도.2 is a cross-sectional view taken along the line A-A of FIG.

상기와 같은 목적은 본 고안에 의해 쉽게 달성되며, 본 고안에 따른 충격 완화용 범퍼 구조물은, 후면 일정부위에 가이드 에어 벤트가 형성되고, 전면이 일체로 성형되는 범퍼 커버와; 상기 범퍼 커버의 내측면에 밀착하여 장착하되, 상기 범퍼 커버와 접촉하는 전방 중앙부에는 서로 이격되어 일차 공기층이 형성되고, 내부에는 이차 공기층이 형성되도록 장착되는 완충부재를 포함하는 것을 특징으로 한다.The above object is easily achieved by the present invention, and the impact relief bumper structure according to the present invention, a guide air vent is formed on a predetermined rear portion, the front and the bumper cover integrally molded; It is mounted in close contact with the inner surface of the bumper cover, the front center portion in contact with the bumper cover is spaced apart from each other to form a primary air layer, it characterized in that it comprises a cushioning member mounted to form a secondary air layer.
이하, 첨부한 도면을 참조로 하여 본 고안의 바람직한 실시예를 상술하고, 도면 전체를 통하여 동일한 부분에는 동일한 도면부호를 사용하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the same reference numerals will be used for the same parts throughout the drawings.
도 3은 본 고안에 따른 충격완화용 범퍼 구조물의 개략적인 구성 단면도이고, 본 고안에 따른 충격완화용 범퍼 구조물은 범퍼 커버(22), 완충 부재(24) 등으로 이루어진다.3 is a schematic cross-sectional view of a shock-absorbing bumper structure according to the present invention, the shock-absorbing bumper structure according to the present invention consists of a bumper cover 22, a buffer member 24 and the like.
상기 범퍼 커버(22)는 후면 일정부위에 가이드 에어 벤트(30)가 형성되고, 전면(全面)이 일체로 성형되는데 상기 에어 벤트(30)의 직경은 다수의 소경으로 형성되는 것이 바람직하며 이것은 차량 충돌시 발생되는 충격량을 완만하게 연속하여 분산시키는 효과가 있기 때문이다.The bumper cover 22 has a guide air vent 30 formed at a predetermined rear surface thereof, and a front surface of the bumper cover 22 is integrally formed. The diameter of the air vent 30 is preferably formed of a plurality of small diameters. This is because there is an effect of slowly and continuously dispersing the amount of impact generated during a collision.
상기 완충 부재(24)는 상기 범퍼 커버(22)의 내측면에 밀착시켜 부착시키는 고무부재로, 상기 범퍼 커버(22)와 접촉하는 전방 중앙부에는 서로 이격되어 일차공기층(26)이 형성되고, 내부에는 상기 가이드 에어 벤트(30)와 연통되어 형성되는 이차 공기층(28)이 내설된다.The buffer member 24 is a rubber member that adheres to the inner surface of the bumper cover 22 to be attached. The front center portion contacting the bumper cover 22 is spaced apart from each other to form a primary air layer 26. There is a secondary air layer 28 is formed in communication with the guide air vent (30).
본 고안의 상기와 같은 구성으로, 차량과 외부물체가 충돌되면 상기 범퍼 커버(22)가 받는 충격량은 일차적으로 상기 일차 공기층(26)이 이를 흡수하고, 이차적으로는 상기 이차 공기층(28)의 공기가 상기 충격량을 상쇄하고, 삼차적으로 상기 에어 벤트(30)에서 공기가 분출되면서 충격 에너지는 분산 흡수되면서 완화된다.With the above-described configuration of the present invention, when the vehicle and the external object collide, the impact amount received by the bumper cover 22 is primarily absorbed by the primary air layer 26, and secondly, the air of the secondary air layer 28 Cancels the impact amount, and as the air is ejected from the air vent 30, the impact energy is alleviated by dispersion absorption.
전술한 바와 같이, 본 고안은, 차량의 충돌시 범퍼가 외부로 부터 받는 충격력을 흡수 및 분산시킴으로서, 충격에 대한 안전성능을 향상시켜 운전자의 안전을 확보할 수 있고, 차량의 상품성을 증대시킬 수 있게 된다.As described above, the present invention, by absorbing and dispersing the impact force that the bumper received from the outside in the event of a collision of the vehicle, it is possible to improve the safety performance against the impact to ensure the driver's safety, and to increase the merchandise of the vehicle Will be.
이상에서 본 고안을 특정의 바람직한 실시예에 관련하여 도시하고 설명하였지만, 이하의 실용신안등록청구의 범위에 의해 마련되는 본 고안의 정신이나 분야를 이탈하지 않는 범위내에서 본 고안이 다양하게 개조 및 변경될 수 있다는 것을 당업계에서 통상의 지식을 가진자라면 용이하게 이해할 수 있을 것이다.Although the present invention has been illustrated and described with reference to certain preferred embodiments, the present invention has been variously modified and modified without departing from the spirit or the field of the present invention provided by the following utility model registration claims. It will be readily understood by those skilled in the art that changes may be made.
