본 발명은 차량범퍼의 강화구조에 관한 것으로, 특히 스프링과 측면보강재를 사용하여 정면충돌에 대한 충격흡수를 높여 안정성을 강화시킨 차량범퍼의 강화구조에 관한 것이다.The present invention relates to a reinforcing structure of a vehicle bumper, and more particularly, to a reinforcing structure of a vehicle bumper having improved stability by increasing shock absorption against frontal collisions using a spring and a side reinforcement material.

일반적으로 차량범퍼는 차체의 전·후부위에 장착되어 충돌시 발생되는 충격을 흡수시켜 차체의 변형을 방지하면서 차체내의 승객이 보호될 수 있도록 된 장치로서 충돌시 충격의 흡수를 높이기 위해 댐퍼(DAMPER)흡수방식, 포옴(FOAM)흡수방식, 플래스틱(PLASTIC)구조물흡수방식등과 같은 여러가지 형식의 범퍼강화구조가 사용되었다.In general, the vehicle bumper is mounted on the front and rear of the vehicle body to absorb the shock generated during the collision to prevent the deformation of the vehicle body and to protect the passengers in the vehicle body. Various types of bumper-reinforced structures, such as absorption method, foam absorption method, and plastic structure absorption method, are used.

이중 댐퍼에 의해 충격의 흡수를 높이도록 된 댐퍼흡수방식은 (A)에 도시된 바와 같이, 범퍼페시어(102)와 차체의 지지프레임(101) 사이에는 보강재(106)에 고정보올트(105)를 매개로 고정된 댐퍼(103)가 취부되어 충돌시 가해지는 충격이 상기 댐퍼(103)를 흡수시키게 된다.Damper absorption method is to increase the absorption of the impact by the double damper is, as shown in (A), the high information olt 105 in the reinforcement 106 between the bumper passer 102 and the support frame 101 of the vehicle body The damper 103 fixed through a) is mounted to absorb the damper 103 when a shock is applied.

그러나, 이와같은 댐퍼흡수방식은 측면충돌시 적은 충돌에는 매우 취약하고 한번 충격이 가해지게 되면 댐퍼(103)내의 오일이 누유되어 사용하지 못하게 되는 문제점이 있었다.However, such a damper absorption method is very vulnerable to small collisions during side collisions, and once the impact is applied, oil in the damper 103 is leaked and cannot be used.

상기 댐퍼흡수방식을 보완하기 위해 (B)에 다른 실시예인 포옴흡수방식이 도시되어 있는 바, 범퍼페시어(202)와 자체의 지지프레임(201) 사이에는, 상기 범퍼페시어(202)를 따라 설치된 일정한 두께를 갖는 포옴(207)과, 이 포옴(207)에 접촉되어 설치된 일정한 두께를 갖는 보강재(206) 및 이 보강재(206)를 지지하고 고정하기 위해 지지프레임(201)에 고정보올트(205)와 너트(205a)를 매개로 고정된 스트레이(203)가 취부되어 충돌시 가해지는 측면 및 정면에 대한 충격을 흡수하게 된다.In order to complement the damper absorption method (B) is shown in another embodiment the foam absorption method, between the bumper passer 202 and its support frame 201, along the bumper passer 202 A foam 207 having a predetermined thickness, a reinforcing material 206 having a predetermined thickness installed in contact with the foam 207, and a high information olt on the support frame 201 to support and fix the reinforcing material 206. The stray 203 fixed through the 205 and the nut 205a is mounted to absorb the impact on the side and the front that are applied during the collision.

그러나, 이와 같은 포옴흡수방식은 포옴(207)을 범퍼페시어(202)를 따라 일정한 두께로 장착되어야만 하므로 이에 따른, 설정공간이 필요하게 되어 구조룸이 공간이 상당히 커지게 되는 등의 문제가 있었다.However, such a foam absorption method has to be equipped with a predetermined thickness along the bumper passer 202, the foam 207, according to this, there is a problem such that the space required to set the space is considerably large. .

상기 포옴흡수방식을 보완하기 위해 (C)에 따른 실시예인 플래스틱구조물 흡수방식이 도시되어 있는바, 범퍼페시어(302)와 차체의 지지프레임(301) 사이에는, 플래스틱보강재(206)에 고정보울트(305)를 매개로 고정된 스트레이(3030가 상기 지지프레임(301)의 내부로 삽입되어 충돌시 가해지는 정면 및 측면에 대한 충격을 흡수하게 된다.In order to supplement the foam absorbing method, a plastic structure absorbing method according to the embodiment according to (C) is shown. Between the bumper passer 302 and the support frame 301 of the vehicle body, a high information bolt on the plastic reinforcing material 206 is provided. The stray 3030 fixed through 305 is inserted into the support frame 301 to absorb impacts on the front and side surfaces applied during the collision.

그러나, 이와같은 플래스틱구조물 흡수방식은 충돌시 충격에 따른 변형범위가 크게되어 이에따른 충격흡수변위공간이 상당히 커져야만되는 문제가 있었다.However, such a plastic structure absorption method has a problem that the deformation range according to the impact at the time of impact is large, so that the shock absorption displacement space must be considerably large.

이에 본 발명은 위와같은 문제점을 해소하기 위해 발명된 것으로, 범퍼페시어와 지지프레임 사이에 스프링을 매개로 보강재가 장착됨과 더불어, 측면부위에는 확장플랜지와 측면플랜지로 이루어져 부채꼴형상으로 된 측면보강재가 장착되어 정면충돌시 상기 보강재와 스프링에 의해 2중으로 충격이 흡수될 뿐만 아니라, 측면충돌시 상기 측면보강재에 의해 충격이 흡수되도록 된 차량범퍼의 강화구조를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the above problems, the reinforcement is mounted between the bumper passer and the support frame via a spring, and the side portion of the side reinforcement in the shape of a fan made of an expansion flange and a side flange The purpose of the present invention is to provide a reinforcing structure of a vehicle bumper, in which a shock is absorbed by the reinforcing member and the spring in the event of a frontal collision, and the shock is absorbed by the side reinforcing material in the case of a side collision.
