본 고안은 자동차의 측면충돌시에 승객의 피해를 최소화할 수 있게 하는 자동차의 측면충돌 보강구조에 관한 것으로, 더 자세하게는 측면충돌시에 차내의 플로어로 전달되는 충격에너지를 더욱 효과적으로 분산, 흡수할 수 있도록 개선한 것에 관한 것이다.The present invention relates to a side collision reinforcement structure of a vehicle to minimize the damage of passengers in the event of a side collision of the vehicle, and more particularly, to more effectively disperse and absorb the impact energy transmitted to the floor of the vehicle during side collision. It's about making improvements.

일반적으로 자동차를 운행함에 있어서는 충돌이나 추돌 등에 의해 자동차의 사방 각 부위에 외부 충격이 가해질 우려가 있게 되는 바, 이와 같은 외부충격이 차체에 가해지게 되면 차체의 손상은 물론 차내에 탑승한 각 승객이 신체적, 정신적인 피해를 입게 되기 마련이다.In general, when driving a car, an external shock may be applied to all parts of the car due to a collision or a collision. When such an external shock is applied to the car body, each passenger in the car is damaged as well as the car body is damaged. Physical and mental damage will occur.

따라서 자동차에서는 차체의 각 부위에 가해질 수 있는 외부 충격에 효과적으로 대응할 수 있도록 하여 운행안정성을 더욱 높이기 위한 보강구조 및 충격완화구조가 마련된다.Therefore, the automobile is provided with a reinforcing structure and a shock-absorbing structure to increase the operational stability by effectively responding to the external impact that can be applied to each part of the body.

본 고안은 특히 도아가 장착되는 자동차의 측면에 가해지는 외부 충격에 대해 효과적으로 대응할 수 있도록 하는 자동차의 측면충돌 보강구조에 관계하는 것인 바, 종래의 측면충돌 보강구조는 제1도와 같이 도아(10')의 내부에 임팩트바(20';impact bar)만을 설치하는 단순한 형태의 것이 주로 사용되었다.The present invention particularly relates to a side collision reinforcement structure of a vehicle that can effectively respond to external impacts applied to the side of the vehicle on which the door is mounted, the conventional side collision reinforcement structure is as shown in FIG. The simple form of installing only the impact bar (20 ';) inside the') was mainly used.

그러나 일반적으로 도아(10')의 하단부는 실사이드(30';sill side)의 상부와 오버랩(overlap)되기 때문에 상기 종래의 구조에 있어서는 측면충돌시에 임팩트바(20')에 전달된 충격에너지가 아무런 보강수단도 경유하지 않고 실사이드(30')을 통해 플로어(40';floor)에 전달되므로 플로어(40')의 변형량이 많게 되고, 그에 따라 승객의 안전성이 크게 떨어지는 문제가 있었다.However, in general, since the lower end portion of the door 10 'overlaps with the upper portion of the seal side 30', the impact energy transmitted to the impact bar 20 'during side impact in the conventional structure. Is transmitted to the floor 40 'through the sealside 30' without passing through any reinforcing means, so the deformation amount of the floor 40 'is increased, thereby greatly reducing the safety of the passengers.

본 고안은 상기 종래 구조의 문제점을 감안하여 안출한 것이며, 그 목적은 내부에 임팩트바가 장착된 도아에 가해지는 외부의 충격에너지를 더욱 효과적으로 분산, 흡수하는 것에 의해 플로어의 변형을 최소화할 수 있게 함으로써 승객의 안전성을 제고할 수 있게 하는 자동차의 측면충돌 보강구조를 제공하는 데에 있는 것이다.The present invention has been devised in view of the problems of the conventional structure, and its purpose is to minimize the deformation of the floor by more effectively dispersing and absorbing the external impact energy applied to the door with the impact bar mounted therein. It is to provide a side collision reinforcement structure of a vehicle that can improve passenger safety.

본 고안은 상기의 목적을 달성하기 위하여 임팩트바의 하단에 보강브라켓트를 설치하는 한편 실사이드의 상부 전면에 걸림부재를 설치하고, 도아의 후하부에 걸림홈을 마련하는 것을 특징으로 하며, 이하 그 구체적인 내용을 첨부도면에 도시한 한 바람직한 실시예를 통하여 더욱 자세히 설명하면 다음과 같다.The present invention is characterized in that to install a reinforcing bracket at the bottom of the impact bar to install the locking member on the upper front side of the seal side, and to provide a locking groove in the rear lower portion of the door to achieve the above object, The specific contents will be described in more detail with reference to one preferred embodiment shown in the accompanying drawings.

즉, 본 고안은 제2도와 같이 도아(10)의 내부에 임팩트바(20)가 설치되고, 도아(10)의 하단부가 실사이드(30)의 상부와 오버랩되는 자동차에 있어서, 상기 도아(10)의 내부의 임팩트바(20)의 하부에 보강브라켓트(12)를 설치하는 한편 실사이드(30)의 전방 상부에 L형의 걸림부재(13)를 설치하고, 도아(10)의 후하부에 이 걸림부재(13)에 삽입되는 걸림홈(11)을 형성하여서 되는 것이다.That is, in the present invention, the impact bar 20 is installed in the inside of the door 10 as shown in FIG. 2, and the lower end of the door 10 overlaps the upper part of the seal side 30. Reinforcing bracket 12 is installed in the lower part of the impact bar 20 inside the inside, while the L-shaped locking member 13 is installed in the front upper part of the seal side 30, and in the rear lower part of the door 10 It is to form a locking groove 11 to be inserted into the locking member (13).

도면부호 중 미설명부호 40은 플로어이다.Reference numeral 40 in the drawing denotes a floor.

상기와 같이 구성된 본 고안에 있어서는 도아(10)가 장착된 차량의 측면으로부터 외부 충격이 가해지는 경우에 도아(10)애 내장된 임팩트바(20)를 통해 그 충격에너지를 흡수하게 되고, 흡수된 충격에너지의 일부는 보강브라켓트(12)로 전달되어 걸림홈(11)에 결합된 걸림부재(13)를 통해 실사이드(30)로 전달되며, 실사이드(30)를 통해 플로어(40)로 전달된다.In the present invention configured as described above, when an external shock is applied from the side of the vehicle on which the door 10 is mounted, the impact energy is absorbed through the impact bar 20 embedded in the door 10 and absorbed. A part of the impact energy is transmitted to the reinforcing bracket 12 to the seal side 30 through the locking member 13 coupled to the locking groove 11, and to the floor 40 through the seal side 30. do.

따라서 본 고안에 의하면 외부의 충격력이 임팩트바(20)와 보강브라켓트(12), 걸림홈(11), 걸림부재(13)를 거쳐 실사이드(30)로 전달되는 과정에서 효과적으로 분산되어 흡수될 수 있게 되므로 최종적으로는 극히 일부의 충격에너지만이 플로어(40)에 작용하게 되고, 그에 따라 플로어(40)의 변형량을 최소화할 수 있게 됨은 물론 차내에 탑승한 승객의 피해를 크게 줄일 수 있게 된다.Therefore, according to the present invention, the external impact force can be effectively dispersed and absorbed in the process of being transmitted to the seal side 30 through the impact bar 20, the reinforcing bracket 12, the locking groove 11, and the locking member 13. Finally, only a small part of the impact energy acts on the floor 40, thereby minimizing the amount of deformation of the floor 40, and of course, greatly reducing the damage of passengers in the vehicle.

이상에서와 같이 본 고안은 임팩트바(20)가 설치된 도아(10)에 가해지는 충격력이 플로어(40)에 이르기까지에 여러 분산부재 및 분산구조를 거치게 함으로써 플로어(40)의 변형을 방지함은 물론 승객의 안전을 도모할 수 있게 한 것으로, 그 실사용에 있어서 자동차의 안정성을 일층 제고하여 상품성을 크게 향상시킬 수 있게 되고, 제품의 신뢰성을 제고할 수 있게 되는 신규 유용의 실용적인 고안인 것이다.As described above, the present invention prevents the deformation of the floor 40 by passing through the various dispersion members and the dispersion structure until the impact force applied to the door 10 having the impact bar 20 is installed on the floor 40. Of course, it is possible to improve the safety of the passengers, it is a practical design of the new useful to be able to enhance the stability of the car in the actual use, and to greatly improve the product quality, and to improve the reliability of the product.
