본 발명은 자동차용 충격흡수 프레임에 관한 것으로, 특히 자동차의 정면 충돌시 프레임 전단부에서 충격을 보다 크게 흡수하도록 개선된 구조의 충격흡수 프레임에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorbing frame for an automobile, and more particularly, to a shock absorbing frame having an improved structure to absorb more impact at a front end of a frame during a frontal collision of a vehicle.
일반적으로 자동차는 충돌시의 충격을 가능한 많이 차체에서 흡수하여 탑승자에게 전달되지 않도록 설계된다. 자동차 충돌시 충격은 일차적으로 범퍼와 프레임 전단부에서 흡수되고 이어서 바디에서 흡수하도록 되어 있으며 프레임과 바디의 과도한 변형으로 탑승자가 부상을 입지 않도록 설계되어야 한다.In general, cars are designed to absorb the impact of a collision as much as possible from the body and not be transmitted to the occupant. In a car crash, the shock is primarily absorbed by the bumper and the front end of the frame and then by the body, and should be designed so that the occupant is not injured by excessive deformation of the frame and the body.
자동차 프레임 전단부에서 충격흡수를 위한 종래 프레임(1)을 제1도와 제2도에 전달부만 개략적으로 도시된 바와 같이 전단부에 충격흡수를 위한 벨로우즈형의 주름부(2)를 형성하거나 보조프레임(3)을 형성하였다.Conventional frame 1 for shock absorption at the front end of an automobile frame is formed or assisted by forming bellows-shaped pleats 2 for shock absorption at the front end as schematically shown in FIGS. The frame 3 was formed.
그러나, 이와 같은 구조로 흡수가능한 충격량이 극히 제한적이고, 제조 비용이 과다하고 프레임 전단부의 변형시 프레임(1)을 수리하여 사용할 수 없는 단점이 있었다.However, such a structure has a disadvantage that the absorbable impact amount is extremely limited, the manufacturing cost is excessive, and the frame 1 cannot be repaired and used when the frame front end is deformed.
본 발명의 목적은 상술한 종래 기술의 단점을 해소하여 충격흡수가능하며 비교적 작은 크기의 충격시 메인프레임이 변형되지 않도록 하고 제조비용이 큰 증가 없는 구성의 충격 흡수 프레임을 제공하는 것이다.SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the prior art and to provide a shock absorbing frame that is shock-absorbing, prevents the mainframe from deforming upon impact of a relatively small size, and has no increase in manufacturing cost.
본 발명에 의한 자동차용 충격흡수 프레임은 메인프레임 전단부 외측으로 부분적으로 끼워지는 보조프레임을 제공하며, 상기 보조프레임의 후단부 측부에 노치형 개구부를 형성하고 그 개구부를 통하여 돌출되게 메인프레임에 쐐기형 돌기부를 형성하고, 상기 돌기부 앞쪽의 보조프레임 측부에 스틸밴드를 접합하여 충돌시의 충격력에 의해 보조프레임이 후방으로 밀리게 되면 메인프레임의 쐐기에 의해 보조프레임의 쐐깃형 개구부가 확대되면서 스틸밴드가 파단되어 메인프레임의 변형에 의한 충격흡수전에 1차적으로 충격력을 흡수하도록 구성되어 있다.The shock absorbing frame for automobiles according to the present invention provides an auxiliary frame that is partially fitted to the outside of the front end of the main frame, and forms a notched opening at the rear end side of the auxiliary frame and weds the main frame to protrude through the opening. If the auxiliary frame is pushed backward by the impact force at the time of collision by joining the steel band to the side of the auxiliary frame in front of the protrusion, the wedge-shaped opening of the auxiliary frame is enlarged by the wedge of the main frame. Is broken and is configured to primarily absorb impact force before shock absorption due to deformation of the mainframe.
이하 본 발명의 일실시예를 도시한 첨부 도면을 참고하여 본 발명을 상세히 서명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing an embodiment of the present invention.
제3도는 본 발명에 따른 충격흡수 프레임을 도시하고 있다. 메인프레임(10)의 전단부에 그 외측으로 보조프레임(11)이 끼워지며, 보조프레임(11)의 후단부 일측부에 노치형의 개구부(12)가 형성되어 있다.3 shows a shock absorbing frame according to the present invention. The auxiliary frame 11 is fitted to the front end of the main frame 10 to the outside thereof, and the notched opening 12 is formed at one side of the rear end of the auxiliary frame 11.
상기 보조프레임(11)의 개구부(12)에 대응한 위치의 메인프레임(10)에는 쐐기형 돌기부(13)가 형성되어 보조프레임 장착시 개구부(12)의 후측에서 돌기부(13)가 돌출되게 된다.The main frame 10 at the position corresponding to the opening 12 of the auxiliary frame 11 is formed with a wedge-shaped protrusion 13 so that the protrusion 13 protrudes from the rear side of the opening 12 when the auxiliary frame is mounted. .
상기 보조프레임(11)의 개구부(12)는 그 개구된 폭이 앞쪽에서 뒤쪽으로 증대되게 예를 들어 높이가 큰 삼각형을 옆으로 누인 형상으로 형성된다.The opening 12 of the auxiliary frame 11 is formed in a shape of, for example, a triangle having a large height sideways so that the opening width thereof is increased from the front side to the rear side.
또한, 개구부(12)를 수직으로 걸쳐 지나도록 스틸밴드(14)가 보조프레임(11)의 측면에 리벳 또는 용접과 같은 공지의 접합수단으로 접합된다.In addition, the steel band 14 is joined to the side of the auxiliary frame 11 by known joining means such as riveting or welding so as to vertically pass through the opening 12.
제4도는 제3도의 프레임을 선 A-A에 의해 절취한 단면도로서 메인프레임(10) 보조프레임(11)이 결합된 관계를 도시하고 있다.4 is a cross-sectional view of the frame of FIG. 3 taken along line A-A, and illustrates a relationship in which the main frame 10 and the auxiliary frame 11 are coupled to each other.
본 발명에 따른 자동차 프레임 전단부를 상술한 바와 같이 구성함으로써, 자동차의 전방 충돌시 그 충격력에 의해 보조프레임(11)은 메인프레임(10)상에서 슬라이드 되면서 후방으로 밀리게 되며, 이때 보조프레임(11)의 노치형 개구부(12)을 통하여 돌출된 메인프레임(10)의 돌기부(13)에 의해 개구부(12)가 확대되는 1차적 충격흡수과정과, 보조프레임(11)이 계속 후방으로 밀리면서 스틸밴드(19)가 돌기부(13)에 의해 파단되는 2차적 충격흡수과정에서 충격력이 흡수된다.By configuring the front end of the vehicle frame according to the present invention as described above, the auxiliary frame 11 is pushed to the rear while sliding on the main frame 10 by the impact force during the front collision of the vehicle, wherein the auxiliary frame 11 The primary shock absorbing process in which the opening 12 is enlarged by the protrusion 13 of the main frame 10 protruding through the notched opening 12 of the main frame 10, and the auxiliary frame 11 continues to push backwards, and the steel band Impact force is absorbed in the secondary shock absorption process in which 19 is broken by the protrusion 13.
상기와 같은 1차적 충격흡수과정에서 메인프레임(10)은 전혀 손상되지 않으므로, 종래 프레임 자체의 전단부가 충격에 의해 변형되면 수리비용이 크게 부담되는 것에 비하여 경제적 및 자원절약면에서 큰 잇점이 있으며, 본 발명에 따른 보조프레임(11)의 형성을 위한 부품수도 많지 않고 작업도 간편하여 저렴한 뿐만 아니라 프레임측에서의 보다 큰 충격흡수로 탑승자의 안전성이 크게 개선된다.Since the main frame 10 is not damaged at all in the primary shock absorption process as described above, when the front end portion of the conventional frame itself is deformed by the impact, there is a great advantage in terms of economic and resource savings as compared with a large repair cost. The number of parts for the formation of the auxiliary frame 11 according to the present invention is not much and the operation is simple and inexpensive, and the safety of the occupant is greatly improved due to the larger shock absorption at the frame side.
제3도와 4도에는 보조프레임(11)의 노치형 개구부(12) 및 스틸밴드(14), 그리고 메인프레임(10)의 쐐기형 돌기부(13)가 일측부에만 구성된 것으로 도시되어 있으나, 이러한 구성을 메인프레임(10) 및 보조프레임(11)의 양측부에 각각 형성하는 것도 가능하며, 이 경우에는 보조프레임(11)을 통해 메인프레임(10)으로 전달되는 충격력이 프레임에 대칭적으로 작용하므로 보다 효과적이다.3 and 4, the notched opening 12 and the steel band 14 of the auxiliary frame 11, and the wedge-shaped protrusion 13 of the main frame 10 are shown to be configured only on one side, but such a configuration It is also possible to form the respectively on both sides of the main frame 10 and the auxiliary frame 11, in this case, since the impact force transmitted to the main frame 10 through the auxiliary frame 11 acts symmetrically on the frame More effective.
