Description

자동차의 범퍼 {BUMPER FOR VEHICLE}Bumper of car {BUMPER FOR VEHICLE}

본 발명은 자동차의 범퍼에 관한 것이다.The present invention relates to a bumper of a motor vehicle.

일반적으로 자동차의 범퍼(bumper)는 자동차의 전면과 후면에 마련되어 충돌사고시 충격력을 흡수함으로써 탑승자의 보호를 도모하는 기능을 수행한다.In general, a bumper of a vehicle is provided at the front and rear of the vehicle to absorb the impact force in a crash, thereby protecting the occupant.

도 3에는 이러한 자동차 범퍼의 일반적인 예를 나타내 보였는 바, 이는 차체의 길이 방향으로 설치되는 프레임(2)을 구비한다.3 shows a general example of such an automobile bumper, which has a frame 2 installed in the longitudinal direction of the vehicle body.

그리고 이 프레임(1)의 단부와 전체 범퍼(1)를 결합 시키기 위한 범퍼 스테이(3)와, 범퍼 스테이(3)와 결합되는 범퍼 레일(4) 그리고 범퍼 레일(4)을 커버링하는 범퍼 커버(5)를 구비한다.And a bumper stay (3) for joining the end of the frame (1) and the entire bumper (1), a bumper rail (4) coupled to the bumper stay (3) and a bumper cover for covering the bumper rail (4) 5).

이때 범퍼 커버(5)와 범퍼 레일(4) 사이에는 충돌시 충격을 흡수하는 업소버 (6)가 개재된다.At this time, between the bumper cover 5 and the bumper rail 4 is an absorber (6) for absorbing the shock during the collision.

이러한 구성을 갖는 범퍼(1)는 충돌시 범퍼 커버(5)의 소성 변형과 업소버 (6)를 통해 충격을 흡수하고, 동시에 범퍼 레일(4)과 범퍼 스테이(3)를 거쳐 프레임(2)상으로 충격을 분산 시킴으로써 탑승자의 안전을 도모하고 있다.The bumper 1 having such a structure absorbs the impact through the plastic deformation of the bumper cover 5 and the absorber 6 during collision, and at the same time passes on the frame 2 via the bumper rail 4 and the bumper stay 3. By distributing the impact, the passenger's safety is promoted.

한편, 이러한 범퍼(1)에 있어서, 범퍼(1)의 중앙부분과 전봇대등과 같은 폴(pole;P)이 충돌될 때 범퍼(1)의 중앙 부분은 범퍼 스테이(3)에 의해 지지되지 않은 상태이기 때문에 상대적으로 취약하여 쉽게 변형 및 파손이 유발되게 된다.On the other hand, in this bumper 1, when the center portion of the bumper 1 collides with a pole P such as a power pole or the like, the center portion of the bumper 1 is not supported by the bumper stay 3. Because it is a state, it is relatively fragile and easily deforms and breaks.

이를 방지하기 위하여 종래에는 도 4에 나타내 보인 바와 같이 범퍼 레일(4)의 중앙 외측면에 강성을 보강하기 위한 레인포스(7)를 결합시키고 있다.In order to prevent this, as shown in FIG. 4, a rain force 7 for reinforcing rigidity is coupled to the central outer surface of the bumper rail 4.

그러나 이러한 종래 범퍼에 있어서는, 레인포스(7)를 통해 어느정도의 강성은 보강한 것이지만, 범퍼 레일(4)의 변형을 방지할 수 없는 것이어서, 수리비의 상승을 초래하는 문제점이 야기되며, 또한 충분한 변형 공간부를 요망함으로써 범퍼 레일(4)의 과도한 돌출 상태가 필요로 하여 디자인의 자유도를 저해하는 요인이 되고 있다.However, in such a conventional bumper, although a certain amount of rigidity is reinforced through the rain force 7, the deformation of the bumper rail 4 cannot be prevented, resulting in a problem of an increase in repair cost, and also sufficient deformation. By requesting the space portion, an excessive protruding state of the bumper rail 4 is required, which is a factor that hinders the degree of freedom in design.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 폴등과 중앙부분의 충돌시 범퍼 레일의 변형을 감소시킬 수 있어 수리비의 상승을 방지할 수 있으며, 특히 범퍼 레일의 돌출량을 축소할 수 있어 디자인 자유도를 향상시킬 수 있는 자동차 범퍼를 제공함에 그 목적이 있다.The present invention was created in order to solve such a conventional problem, it is possible to reduce the deformation of the bumper rail during collision between the pole and the center portion can prevent the increase in repair costs, in particular to reduce the amount of protrusion of the bumper rail The purpose is to provide a car bumper that can improve design freedom.

상기한 목적을 달성하기 위하여 본 발명은, 바디로 부터 연장 형성된 패널에 스테이를 통해 고정 설치되며 자동차의 주행 방향을 기준으로 하여 외측면으로 만곡되게 형성된 범퍼 레일과; 상기 범퍼 레일의 전면에 위치되는 범퍼 커버와; 상기 범퍼 커버와 범퍼 레일 사이에 개재되어 충격을 흡수하는 압소버와; 상기 범퍼 커버의 중심부와 대응되는 패널의 외측면에 마련되어 범퍼 레일의 중심부 변형을 감소시키는 탄성 브라켓;을 포함하여 된 것을 그 특징으로 한다.In order to achieve the above object, the present invention, the bumper rail is fixed to the panel formed extending from the body through the stay and formed to be curved to the outer surface based on the driving direction of the vehicle; A bumper cover positioned at a front surface of the bumper rail; An absorber interposed between the bumper cover and the bumper rail to absorb a shock; And an elastic bracket provided on an outer surface of the panel corresponding to the center of the bumper cover to reduce the center deformation of the bumper rail.

도 1은 본 발명에 따른 자동차 범퍼를 개념적으로 나타낸 평면도이고, 도 2는 변형 방지수단을 발췌하여 나타낸 사시도로써, 이하에는 도 3을 참조하여 설명하며 동일부품에는 동일한 부호를 부여하였다.1 is a plan view conceptually illustrating an automobile bumper according to the present invention, and FIG. 2 is a perspective view showing an anti-deformation means, which will be described below with reference to FIG.

먼저 도 3을 참조하면, 차체의 길이 방향으로 설치되며 바디로 부터 연장 형성된 패널(8)과 결합되는 프레임(2)을 구비한다.First, referring to FIG. 3, a frame 2 is installed in the longitudinal direction of the vehicle body and coupled to a panel 8 extending from the body.

그리고 이 프레임(1)의 단부와 전체 범퍼(1)를 결합 시키기 위한 범퍼 스테이(3)와, 범퍼 스테이(3)와 결합되는 범퍼 레일(4) 그리고 범퍼 레일(4)을 커버링하는 범퍼 커버(5)를 구비한다.And a bumper stay (3) for joining the end of the frame (1) and the entire bumper (1), a bumper rail (4) coupled to the bumper stay (3) and a bumper cover for covering the bumper rail (4) 5).

이때 범퍼 커버(5)와 범퍼 레일(4) 사이에는 충돌시 충격을 흡수하는 업소버(6)가 개재된다.At this time, between the bumper cover 5 and the bumper rail 4 is an absorber 6 is absorbed in the impact during the collision.

한편, 전술한 범퍼 레일(4)의 중심부와 대응되는 패널(8)의 외측면에는 실질적으로 본 발명의 특징적인 요소를 갖고 있는 것으로서, 폴(P) 등에 중심부가 충돌되었을 때 변형을 감소시키는 탄성 브라켓(10)이 고정 설치된다.On the other hand, the outer surface of the panel 8 corresponding to the center portion of the bumper rail 4 described above has substantially the characteristic elements of the present invention, and is elastically reducing deformation when the center portion collides with the pole P or the like. The bracket 10 is fixedly installed.

이러한 탄성 브라켓(10)의 상세한 구조를 보면, 도 2에 나타내 보인 바와 같이, 패널(8)의 외측면에는 서로 소정간격으로 고정편(11)이 예컨대 고정나사나 용접 등의 방법에 의해 고정 설치된다.Referring to the detailed structure of the elastic bracket 10, as shown in Fig. 2, the fixing piece 11 is fixedly installed on the outer surface of the panel 8 at predetermined intervals by, for example, a fixing screw or welding. do.

이 고정편(11)은 탄성편(12)에 의해 일체로 연결되는 바, 탄성편(12)은, 범퍼 레일(4)과 접촉될 수 있도록 중심부가 만곡되게 연장 형성된다.The fixing piece 11 is integrally connected by the elastic piece 12, the elastic piece 12 is formed so that the center portion is curved so as to be in contact with the bumper rail (4).

이때 특히 탄성편(12)상에는 좀더 상승된 탄성력을 얻기 위하여 좌,우 방향을 따라 소정폭으로 절개홈(12a)이 형성된다.In this case, in particular, the incision groove 12a is formed on the elastic piece 12 in a predetermined width along the left and right directions in order to obtain a more elevated elastic force.

이러한 구성을 갖는 본 발명은, 전봇대등과 같은 폴(P)에 차체의 중심부가 충돌되면, 범퍼 레일(4)을 감싸고 있는 범퍼 커버(5)의 소성 변형을 통해 그 충격력을 흡수하고 또한 범퍼 커버(5)와 범퍼 레일(4) 사이에 위치된 압소버(6)를 통해 충격력을 분산 흡수한다.The present invention having such a configuration absorbs the impact force through plastic deformation of the bumper cover 5 surrounding the bumper rail 4 when the central portion of the vehicle collides with a pole P such as a power pole or the like, and the bumper cover. The absorbing force is dispersed and absorbed through the absorber 6 positioned between the 5 and the bumper rails 4.

이와동시에 충격력에 의한 범퍼 레일(4)이 변형되는 것은 이 범퍼 레일(4)의 내측면과 접촉되고, 패널(8)상에 고정 설치된 탄성 브라켓(10)에 의해 방지된다.At the same time, the deformation of the bumper rail 4 due to the impact force is prevented by the elastic bracket 10 which is in contact with the inner surface of the bumper rail 4 and is fixed on the panel 8.

이를 좀더 상세히 설명하면, 폴(P)에 의해 가해진 충격력이 범퍼 레일(4)에가해지게 되면, 범퍼 레일(4)을 거쳐 탄성 브라켓(10)의 탄성편(12)에 전달되게 되고, 이 탄성편(12)이 도 1에 가상선으로 나타내 보인 바와 같이 패널(8)을 향해 변형되면서 충격력이 흡수되어 결과적으로 범퍼 레일(4)의 변형을 감소시킬 수 있게된다.In more detail, when the impact force applied by the pole P is applied to the bumper rail 4, it is transmitted to the elastic piece 12 of the elastic bracket 10 via the bumper rail 4. As the elastic piece 12 is deformed toward the panel 8 as shown by an imaginary line in FIG. 1, the impact force is absorbed, and as a result, the deformation of the bumper rail 4 can be reduced.

이상과 같이 본 발명은, 전봇대등과 같은 폴이 취약한 중앙부분에 충돌될 때 발생되는 범퍼 레일의 변형을 패널에 고정 설치된 탄성 브라켓을 통해 감소시킬 수 있게된다.As described above, the present invention, it is possible to reduce the deformation of the bumper rail generated when a pole, such as a pole, such as a pole to the weak through the elastic bracket fixed to the panel.

따라서 수리비의 절감을 도모할 수 있을 뿐만 아니라, 범퍼 레일의 돌출량을 축소시킬 수 있게되어 디자인을 자유롭게 행할 수 있는 이점이 있다.Therefore, it is possible not only to reduce the repair cost, but also to reduce the amount of protrusion of the bumper rails, so that the design can be freely performed.
