본 발명은 자동차용 임팩트빔 구조에 관한 것으로서, 더욱 상세하게는 범퍼커버 내측에 설치되어 차량의 정면 충돌시에 차체를 보호하는 자동차용 임팩트빔 구조에 관한 것이다.The present invention relates to an impact beam structure for an automobile, and more particularly, to an impact beam structure for an automobile installed inside a bumper cover to protect a vehicle body during a frontal collision of the vehicle.

통상적으로 자동차에는 제1도에 도시된 바와 같이 저속충돌시의 차체의 보호를 위해 전후면에 각각 범퍼(1)가 설치되어 있다. 이러한 범퍼는 대략 차종에 따라 5mile/h 이하 또는 2.5mile/h 정도의 속력이내에서 완충효과를 갖도록 제작된다.In general, as shown in FIG. 1, bumpers 1 are respectively installed on the front and rear surfaces to protect the vehicle body during a low-speed collision. These bumpers are designed to have a cushioning effect within a speed of less than 5 miles / h or 2.5 miles / h depending on the vehicle model.

상기 속도는 국가에 따라 차량에 적용하는 법규에 의해 달라지게 되는 것으로 국내에서는 현재 2.5mile/h을 기준으로 하고 있다. 이는 즉, 2.5mile/h 이하의 속력에서 차량 충돌시에 범퍼(1)가 차체 및 전장품 예를들면, 전조등(2) 또는 엔진후드(3) 등에 손상을 주지 않는 성능을 보유해야 하는 것을 의미한다.The speed will vary depending on the laws and regulations that apply to vehicles in different countries. Currently, the speed is based on 2.5 miles / h. This means that the bumper 1 must have the performance of not damaging the vehicle body and the electrical equipment, for example, the headlight 2 or the engine hood 3, at the speed of 2.5 miles / h or less. .

제2도를 참고하여 통상의 범퍼구조를 살펴보면 커버(4) 내측에 임팩트 빔(5)이 설치되고, 임팩트 빔(5)과 커버(4) 사이에는 충격흡수재(6)가 개재된다. 그리고, 임팩트 빔(5)을 차체(8)에 고정시키는 스테이(7)가 구비된다.Referring to FIG. 2, the impact bumper 5 is installed inside the cover 4, and the shock absorber 6 is interposed between the impact beam 5 and the cover 4. And the stay 7 which fixes the impact beam 5 to the vehicle body 8 is provided.

그러나 상기와 같은 종래의 임팩트 빔은 차종에 따라 그 호환이 안 되는 문제를 갖고 있었다.However, such a conventional impact beam had a problem that is not compatible depending on the vehicle model.

즉, 상기한 바와 같이 범퍼는 5mile/h 또는 2.5mile/h 중 선택된 속도에 맞게 설계되어야 하는데, 종래에는 속도변화에 따라 다른 형태의 임팩트 빔(5)을 사용해야 하므로 별도의 금형제작은 물론 그에 따른 제반 부품을 별도로 제조하여야 하므로 속도변화에 따른 호환이 불가능하여 제조원가의 상승요인으로 작용하고 있었다.That is, as described above, the bumper should be designed according to the selected speed of 5 miles / h or 2.5 miles / h. In the related art, a different mold impact beam 5 should be used according to the speed change, so that a separate mold is manufactured as well. Since all parts had to be manufactured separately, it was not compatible with the change of speed, which caused the increase of manufacturing cost.

또한, 종래에는 차폭에 따라 임팩트 빔(5)의 길이가 변형되므로 각각의 차종에 따라 다른 크기의 임팩트 빔(5)을 필요로 하고 있으므로 이 또한 임팩트 빔의 호환성을 저해하는 요인으로 작용하고 있었다.In addition, since the length of the impact beam 5 is deformed in accordance with the vehicle width, the impact beam 5 having a different size is required for each vehicle type, which also acts as a factor that impairs the compatibility of the impact beam.

따라서, 상기와 같은 문제를 해결하기 위하여 제3도 및 제4도에 도시된 바와 같이 본 출원인에 의해 양단에 체결공(12)이 형성되어 있는 수개의 임팩트바(10)와, 상기 임팩트바(10)의 양단을 지지하는 수개의 결합공(22) 및 각각의 결합공(22)을 동축상으로 관통하는 관통공(24)를 갖는 지지부재(20)와, 상기 관통공(24)과 체결공(12)을 통해 삽입되고 분할핀(32)에 의해 이탈이 방지되면서 임팩트바(10)를 지지부재(20)에 고정하는 체결핀(30)을 구비한 것이 개발되어 있다.Therefore, in order to solve the above problems, as shown in FIGS. 3 and 4, the impact bars 10 having the fastening holes 12 formed at both ends by the applicant, and the impact bars ( 10 and a support member 20 having a plurality of coupling holes 22 for supporting both ends of each of the ends 10 and through holes 24 coaxially passing through the respective coupling holes 22, and the through holes 24. Is provided with a fastening pin 30 for inserting through the ball 12 and preventing the impact bar 10 to the support member 20 while being prevented from being separated by the split pin 32.

이에 따르면 임팩트바(10)의 수를 가감하는 것에 의해 임팩트 빔 전체의 강도를 조정하여 차속에 맞게 변형이 가능하고, 또한, 임팩트바의 길이를 크게 하거나 또는 작게 하는 것에 의해 임팩트 빔의 넓이를 조절할 수 있게 되므로 차종에 따라 호환 가능하게 되는 것이다.According to this, the intensity of the entire impact beam can be adjusted by adding or subtracting the number of impact bars 10 so that deformation can be made according to the vehicle speed, and the width of the impact beam can be adjusted by increasing or decreasing the length of the impact bar. It becomes possible to be compatible according to the vehicle model.

그러나 이러한 구조는 상기 임팩트바의 삽입단에서 응력 집중이 발생하여 강도가 저하되는 문제를 갖고 있었다.However, such a structure has a problem in that stress concentration occurs at an insertion end of the impact bar, thereby decreasing strength.

즉, 차량충돌시에 결합공(22)의 입구가 위치하는 임팩트바(10)상의 지점에서 응력이 집중하게 되어 임팩트바(10)가 소정의 충격에 견디지 못하고 상기 응력집중부가 휘어지거나 또는 절단되므로 설정속도 이하에서의 충격에서도 차체를 보호할 수 없으므로 전체적으로 강도를 높여 이를 보완할 수밖에 없는 문제를 갖고 있다.That is, since the stress is concentrated at the point on the impact bar 10 where the inlet of the coupling hole 22 is located at the time of the vehicle crash, the impact bar 10 does not endure a predetermined shock and the stress concentration portion is bent or cut. Since the body cannot be protected even when the impact is below the set speed, the overall strength is increased to compensate for this problem.

이에, 본 발명은 상기한 문제를 고려하여 안출된 것으로서, 그 목적은 임팩트바상의 응력집중을 약화시켜 설정강도를 유지할 수 있는 자동차용 임팩트빔 구조를 제공함에 있다.Accordingly, the present invention has been made in view of the above problems, and its object is to provide an impact beam structure for automobiles that can maintain the set strength by weakening the stress concentration on the impact bar.

이러한 본 발명의 목적은 결합공과 임팩트바 사이에 완충부재를 개재하여 달성될 수 있다.The object of the present invention can be achieved through a buffer member between the coupling hole and the impact bar.

즉, 결합공내에 완충부재를 개재하고 이 완충부재에 임팩트바를 삽입하여 충격시 응력을 분산시켜 임팩트바의 강도를 유지할 수 있게 되는 것이다.In other words, it is possible to maintain the strength of the impact bar by interposing the shock absorbing member in the coupling hole and inserting the impact bar into the shock absorbing member to disperse the stress during the impact.

이하, 본 발명의 바람직한 실시예를 첨부 도면에 의거하여 좀 더 구체적으로 설명하면 다음과 같다.(종래와 동일구성은 부호를 동일하게 설명한다.)Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

제5도에서는 본 발명에 따른 임팩트 빔의 구성이 분해 도시되어 있는데, 양단에 체결공(12)이 형성되어 있는 수개의 임팩트바(10)가 구비되어 있다.5 is an exploded view of the configuration of the impact beam according to the present invention, which has several impact bars 10 having fastening holes 12 formed at both ends thereof.

그리고 상기 임팩트바(10)의 양단을 지지하는 수개의 결합공(22) 및 각각의 결합공(22)을 동축상으로 관통하는 관통공(24)를 갖는 지지부재(20)가 구비된다. 또한 상기 관통공(24)과 체결공(12)를 통해 삽입되고 분할핀(32)에 의해 이탈이 방지되면서 임팩트바(10)를 지지부재(20)에 고정하는 체결핀(30)이 구비되고, 이 체결핀(30)은 분할핀(32)에 의해 이탈이 방지된다.In addition, a support member 20 having a plurality of coupling holes 22 supporting both ends of the impact bar 10 and a through hole 24 penetrating through the coupling holes 22 coaxially is provided. In addition, the fastening pin 30 is inserted through the through hole 24 and the fastening hole 12, and is prevented from being separated by the split pin 32, and a fastening pin 30 is fixed to the support member 20. The fastening pin 30 is prevented from being separated by the split pin 32.

한편, 본 발명은 상기 결합공(22) 내에 삽입되고, 내측으로 상기 임팩트바(10)를 수용하는 완충부재(40)가 구비된다. 이 완충부재(40)는 비교적 완충력이 우수한 고무재질로 이루어져 있다.On the other hand, the present invention is inserted into the coupling hole 22, the shock absorbing member 40 for receiving the impact bar 10 inward is provided. The buffer member 40 is made of a rubber material having a relatively good buffering force.

이와 같은 구성을 갖는 본 발명은 충격이 가해지면 임팩트바(10)에 가해지는 충격은 완충부재에서 순간흡수하며, 그 흡수과정에서 충격을 지지부재(20)와 임팩트바(10)의 결합단에 집중되는 응력이 임팩트바(10)의 내측으로 분산되어진다. 따라서 임팩트바(10)는 응력집중으로 인한 강도 저하를 방지하게 된다.According to the present invention having such a configuration, when an impact is applied, the impact applied to the impact bar 10 is instantaneously absorbed by the shock absorbing member, and the shock is absorbed to the coupling end of the support member 20 and the impact bar 10 during the absorption process. The concentrated stress is distributed to the inside of the impact bar 10. Therefore, the impact bar 10 is to prevent the decrease in strength due to the concentration of stress.

상술한 바와 같이 본 발명에 따른 자동차용 임팩트빔 구조는 임팩트바와 지지부재 사이에 완충부재를 개재하여 충격시 임팩트바의 국부적인 응력집중으로 인한 강도 저하를 미연에 방지할 수 있으므로 임팩트빔의 성능을 향상시킬 수 있는 효과를 갖는 것이다.As described above, the impact beam structure for automobiles according to the present invention can prevent the degradation of strength due to local stress concentration of the impact bar in the event of an impact through a buffer member between the impact bar and the support member, thereby improving the performance of the impact beam. It is to have an effect that can be improved.
