Description

차량용 범퍼 {BUMPER FOR VEHICLE}Car Bumper {BUMPER FOR VEHICLE}

본 발명은 차량용 범퍼에 관한 것이다.The present invention relates to a vehicle bumper.

주지하는 바와 같이 차량용 범퍼는 강판제 및 플라스틱제로 구분되며, 통상적으로 강판제 범퍼는 강판을 ㄷ형으로 형성하여 프레임에 고정하고, 플라스틱제 범퍼는 플라스틱제 범퍼 커버, 발포 플라스틱제 에너지 압소버 및 철제 백빔으로 구성하여 철제 백빔에 형성된 범퍼 스테이를 사이드 멤버에 고정한 것이다.As is well known, a vehicle bumper is divided into steel sheet and plastic, and in general, the steel sheet bumper forms a steel plate in a c shape and is fixed to the frame, and the plastic bumper includes a plastic bumper cover, a foamed plastic energy absorber, and an iron back beam. The bumper stay formed in the iron back beam was fixed to the side member.

상기한 강판제 범퍼는 강성이 큼으로 자기 차량 및 그 탑승자의 보호가 양호하고, 플라스틱제 범퍼는 에너지 압소버가 충격을 흡수함으로서 자기 차량 및 그 탑승자의 보호외에 다른 차량 및 보행자의 충격을 경감토록 한 것이다.The steel plate bumper has a high rigidity, so that the protection of the vehicle and its occupants is good, and the plastic bumper absorbs the impact of the energy absorber to reduce the impact of other vehicles and pedestrians in addition to the protection of the vehicle and its occupants. It is.

그러나 상기한 강판제 범퍼는 다른 차량 및 보행자의 충격흡수가 거의 불가능하고, 플라스틱제 범퍼도 자기 또는 다른 차량과 그 탑승자 및 보행자의 충격을 에너지 압소버가 가지는 재질의 특성만에 의존하여 흡수함으로서 충격흡수가 양호하지 못한 문제점이 있는 것이다.However, the steel plate bumper is almost impossible to absorb shocks of other vehicles and pedestrians, and the plastic bumpers also absorb shocks of self or other vehicles, their occupants, and pedestrians depending only on the characteristics of the material of the energy absorber. There is a problem that the absorption is not good.

본 발명은 상기한 문제점을 시정하여, 자기 또는 다른 차량과 그 탑승자 및 보행자의 충격흡수를 양호하게 할 수 있는 차량용 범퍼를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle bumper capable of correcting the above problems and making it possible to improve shock absorption of a magnetic or other vehicle and its occupants and pedestrians.

상기한 목적을 달성하기 위하여, 본 발명은 범퍼 스테이와, 범퍼 커버와, 상기 범퍼 스테이의 상하에 레일을 고정함과 동시에 범퍼 커버의 내면 하방에 충격 감지레버를 요동할 수 있게 지지하여 상기 레일과 충격 감지레버의 타단을 스톱퍼가 설치된 링케이지로 연결한 충격 감지수단과, 상기 레일에 이동레일을 스프링과 함께 슬라이딩할 수 있게 지지하여 상기 스톱퍼로 록킹하고 범퍼 커버의 내면 중앙에 고정바를 설치하여 고정바의 타단과 이동레일을 링크로 연결한 범퍼 커버 지지수단으로 구성한 것이다.In order to achieve the above object, the present invention is to support the bumper stay, the bumper cover, the upper and lower rails of the bumper stay and at the same time to support the shock detection lever to swing below the inner surface of the bumper cover and the rail and Shock sensing means connecting the other end of the shock detection lever to a ring cage with a stopper, and supporting the movable rail with a spring to slide on the rail to lock with the stopper and fixed by installing a fixing bar in the center of the inner surface of the bumper cover It is composed of a bumper cover support means connecting the other end of the bar and the moving rail by a link.

At least two sets of means 12 are incorporated.

4는 충격 감지수단으로서, 상기 충격 감지수단(4)은 상기 범퍼 스테이(1)의 상하에 레일(5)(5')을 일정간격으로 고정하고, 범퍼 커버(3)의 내면 하방에 충격 감지레버(6)를 요동할 수 있게 지지함과 동시에 상기 충격 감지레버(6)의 타단에 링케이지(7) 즉 충격 감지레버(6)의 타단에 직선 링크(8)를, 직선 링크(8)의 타단에 범퍼 스테이(1)에 설치한 브래킷(미도시)에 지지핀(10)(10')으로 지지한 ㄱ형 링크 (9)(9')를 연결한 후 ㄱ형 링크(9)(9')에 수직으로 스톱퍼(11)(11')를 지지하여서 상기 레일(5)(5')에 지지한 것이다.4 is an impact sensing means, and the impact sensing means 4 fixes the rails 5 and 5 'at regular intervals above and below the bumper stay 1, and detects the impact below the inner surface of the bumper cover 3. The link 6 is supported at the other end of the impact detection lever 6 at the other end of the linkage 7, that is, at the other end of the impact detection lever 6, and the straight link 8 is supported at the other end of the impact detection lever 6. At the other end of the a-type link (9) (9 ') supported by the support pin (10) (10') to the bracket (not shown) installed in the bumper stay (1), and then the a-type link (9) (9 ') The stopper (11) (11 ') is supported perpendicularly to the rail (5) (5').

12는 범퍼 커버 지지수단으로서, 상기 범퍼 커버 지지수단(12)은 상기 레일(5)(5')에 이동레일(13)(13')을 코일 스프링(14)(14')과 함께 슬라이딩할 수 있게 지지함과 동시에 상기 스톱퍼(11)(11')로 록킹하고, 범퍼 커버(3)의 내면 중앙에 고정바(15)를 설치하여 고정바(15)의 타단과 이동레일(13)(13') 사이에 범퍼 스테이 (1)에 브래킷(미도시)으로 지지된 링크(16)(16')를 연결하여서 된 것이다.12 is a bumper cover support means, wherein the bumper cover support means 12 can slide the movable rails 13 and 13 'together with the coil springs 14 and 14' on the rails 5 and 5 '. It is supported so that it can be locked at the same time as the stopper (11) (11 '), and the fixing bar 15 is installed in the center of the inner surface of the bumper cover (3) by the other end of the fixing bar (15) and the moving rail (13) ( 13 ') by connecting links 16 and 16' supported by a bracket (not shown) to the bumper stay 1.

그리고 충격 감지레버(6)의 수직부와 범퍼 커버(3) 사이에 코일 스프링(17)을 설치하여 정상 상태시에 충격 감지레버(6)의 요동을 방지토록 한 것이다.In addition, the coil spring 17 is installed between the vertical part of the shock detection lever 6 and the bumper cover 3 to prevent the shock detection lever 6 from shaking in a normal state.

이상과 같은 본 발명은 스톱퍼(11)(11')가 이동레일(13)(13')을 록킹한 상태 즉 정상상태에서 범퍼 커버(3)에 충격이 가하여지면 충격 감지레버(6)가 충격방향과 동일방향으로 요동함에 따라 직선 링크(8)를 밀고 ㄱ형 링크(9)(9')가 지지핀 (10)(10')을 지점으로 도 1의 화살표 방향으로 회전함으로서 ㄱ형 링크 (9)(9')에 지지된 스톱퍼(11)(11')가 이동레일(13)(13')의 록킹을 해제하는 것이다.In the present invention as described above, the shock detection lever 6 is shocked when the stopper 11, 11 'is applied to the bumper cover 3 in the locked state of the movable rails 13 and 13'. The a-type link (9) by pushing the straight link (8) as it swings in the same direction as the a-type link (9) (9 ') rotates the support pin (10) (10') in the direction of the arrow in FIG. The stoppers 11 and 11 'supported by 9' release the locking of the moving rails 13 and 13 '.

상기와 같이 이동레일(13)(13')의 록킹이 해제되면 이동레일(13)(13')은 코일 스프링(14)(14')의 탄성에 의하여 충격방향과 반대방향으로 이동됨과 동시에 링크(16)(16')의 스톱퍼 연결부분이 벌어짐으로서 고정바(15)를 견인함에 따라 범퍼 커버(3)는 충격방향과 동일방향으로 이동하면서 즉 범퍼 커버(3)가 차체 측으로 축소되면서 코일 스프링(14)(14')에 의하여 충격을 흡수하는 것이기 때문에 자기 또는 다른 차량과 그 탑승자 및 보행자에 가하여지는 충격흡수가 양호하게 되는 것이다.As described above, when the locking of the moving rails 13 and 13 'is released, the moving rails 13 and 13' are moved in the opposite direction to the impact direction by the elasticity of the coil springs 14 and 14 ', and at the same time, the link is removed. As the stopper connection portions of the 16 and 16 'are opened, the bumper cover 3 moves in the same direction as the impact direction, i.e., the bumper cover 3 shrinks toward the vehicle body side as the towing of the fixing bar 15 causes the coil spring to move. Since the shock is absorbed by (14) and (14 '), the shock absorption applied to the magnetic or other vehicle and its occupants and pedestrians becomes good.

이상과 같이 본 발명은 범퍼 스테이와 범퍼 커버 사이에 충격 감지수단을 연결하고, 충격 감지수단과 범퍼 커버 사이에 범퍼 커버 지지수단을 연결하여 충격시에 범퍼 커버를 차체 측으로 축소하면서 충격을 흡수하도록 하였음으로 충격흡수가 양호하면서 차량의 파손을 적게하고, 탑승자 및 보행자의 보호를 증진할 수 있는 것이다.As described above, the present invention connects the shock sensing means between the bumper stay and the bumper cover, and connects the bumper cover support means between the shock sensing means and the bumper cover to reduce the bumper cover toward the vehicle body during shock to absorb the shock. The shock absorption is good while reducing the damage of the vehicle, it is possible to promote the protection of occupants and pedestrians.
