Description
본 고안은 자동차의 오프셋충돌에 대응하기 위한 차체의 보강구조에 관한 것으로, 특히 40% 오프셋충돌시 섀시보조프레임이 후방으로 밀리는 것을 효과적으로 대응할 수 있도록 한 자동차용 차체의 보강구조에 관한 것이다.The present invention relates to a reinforcing structure of a vehicle body to cope with an offset collision of a vehicle, and more particularly, to a reinforcing structure of a vehicle body for effectively coping with the rear side of the chassis auxiliary frame is pushed back when 40% offset collision.
일반적으로 오프셋충돌(OFFSET CRUSH)이란 랩충돌 또는 오프셋 크러시라고도 불리우며, 이는 장애물에 대한 자동차의 부분적인 충돌을 말한다. 충돌실험에서는 자동차의 전폭 중 얼마만큼의 폭이 충돌했는가를 백분율로 나타내어 몇 퍼센트(%)오프셋충골이라고 표현한다. 오프셋은 중심을 벗어나 있는 것으로 대형차와의 충돌이나 사고를 피하기 위하여 운전조작하다가 충돌을 한 경우을 생각한 것이다.Offset collision is also commonly referred to as lap collision or offset crush, which is the partial collision of the vehicle against obstacles. In the collision test, the percentage of the full width of the car collided is expressed as a percentage, which is expressed as a percentage of the offset bone. The offset is off center and is considered to be a collision while driving to avoid a collision or accident with a large vehicle.
종래 승용차에는 도 1에 도시된 것과 같이, 섀시서브프레임(10)이 하부에 배치된 전방사이드멤버(20)와 센터필러사이드멤버(30)가 삼각형상의 스테이(40)를 매개로 결합되어 있다.In the conventional passenger car, as shown in FIG. 1, the front side member 20 and the center pillar side member 30 having the chassis subframe 10 disposed below are coupled to each other via a triangular stay 40.
여기서 상기 센터필러사이드멤버(30)에 스테이(40)가 결합된 상태는 상기 센터필러사이드멤버(30)를 구성하는 내외측센터필러사이드멤버(31,32)중에서 내측센터필러사이드멤버(31)에 고정되어 있다.Here, the state 40 is coupled to the center pillar side member 30 is an inner center pillar side member 31 of the inner and outer center pillar side members 31 and 32 constituting the center pillar side member 30. It is fixed at.
미설명부호 21은 전방사이드멤버의 결합부이고, 31a는 내측센터필러사이드멤버의 결합부이다.Reference numeral 21 is a coupling portion of the front side member, 31a is a coupling portion of the inner center pillar side member.
따라서 상기 전방사이드멤버(20)쪽에서 충격이 전달되어 섀시서브프레임(10)이 후방으로 밀리면 상기 결합부(21,31a)에 의해 고정된 스테이(40)가 이를 지지해 주게 된다.Accordingly, when the shock is transmitted from the front side member 20 and the chassis subframe 10 is pushed backward, the stay 40 fixed by the coupling parts 21 and 31a supports it.
그러나 40% 오프셋 충돌시 섀시서브프레임의 결합부뒷쪽이 적은 변형이 발생하도록 설치된 상기 스테이(40)는 섀시서브프레임(10)에 후방으로의 밀림이 생기면 상기 섀시서브프레임(10)의 체결부(11)을 힌지로 해서 회전운동이 발생하므로 버팀부재로서의 역할을 충분히 하지 못하는 결점이 있었다.However, the stay 40 installed such that the rear side of the coupling portion of the chassis subframe is less deformed when the 40% offset collision occurs, when the rear surface of the chassis subframe 10 is pushed back, the fastening portion of the chassis subframe 10 ( 11) as a hinge, the rotational movement occurs, there was a defect that can not be enough as a brace member.
이에 본 고안은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 내외측센터필러사이드멤버에 스테이를 고정할 수 있도록 구성하여, 40% 오프셋충돌시 섀시보조프레임이 후방으로 밀릴 때 이를 효과적으로 지지할 수 있도록 한 자동차용 차체의 보강구조를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned drawbacks, and it can be configured to fix the stay on the inner and outer center pillar side members, and can effectively support it when the chassis auxiliary frame is pushed backwards at 40% offset collision. The purpose is to provide a reinforcement structure of a vehicle body.

상기와 같은 목적을 달성하기 위한 본 고안 자동차용 차체의 보강구조는, 섀시서브프레임이 배치된 전방사이드멤버와 센터필러사이드멤버가 스테이를 매개로 결합되되, 상기 스테이가 대략⊂자 형상으로 되면서 단면은 중절모자의 중앙을 절단한 상태의 단면을 갖는 한편, 양단은 센터필러사이드멤버를 구성하는 내외측센터필러사이드멤버에 각각 고정됨과 더불어, 상기 전방사이드멤버의 하부에 설치된 섀시서브프레임과 전방사이드멤버에 소정위치가 각각 고정된 것을 특징으로 한다.The reinforcement structure of the vehicle body of the present invention for achieving the above object, the front side member and the center pillar side member in which the chassis sub-frame is arranged is coupled via the stay, the stay is in the shape of a cross-section Has a cross section in the state of cutting the center hat, while both ends are fixed to the inner and outer center pillar side members constituting the center pillar side member, and the chassis subframe and the front side member installed under the front side member. The predetermined position is characterized in that each fixed.
이하 본 고안에 의한 일실시예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안에 따른 자동차의 오프셋충돌에 대응하기 위한 차체의 보강구조를 나타내는 요부사시도이고, 도 3은 도 2의 A - A선 단면도로서, 종래기술을 설명하는 도 1 과 동일한 부위에는 동일한 참조부호를 붙이면서 그 설명은 생략한다.2 is a perspective view showing a reinforcing structure of the vehicle body corresponding to the offset collision of the vehicle according to the present invention, Figure 3 is a cross-sectional view taken along the line A-A of Figure 2, the same in Figure 1 illustrating the prior art The description is omitted while the reference numeral is attached.
본 고안은, 섀시서브프레임(10)이 배치된 전방사이드멤버(20)와 센터필러사이드멤버(30)가 스테이(40)를 매개로 결합된 자동차용 차체의 보강구조에 있어서, 상기 스테이(100)가 ⊂자 형상으로 되면서 단면은 중절모자의 중앙을 절단한 상태의 단면을 갖는 한편, 양단은 센터필러사이드멤버(30)를 구성하는 내외측센터필러사이드멤버(31,32)에 각각 고정됨과 더불어, 상기 전방사이드멤버(20)의 하부에 설치된 섀시서브프레임(10)과 전방사이드멤버(20)에 소정위치가 각각 고정된 구조로 되어 있다.The present invention, in the reinforcement structure of the vehicle body is coupled to the front side member 20 and the center pillar side member 30 in which the chassis subframe 10 is disposed via the stay 40, the stay 100 ) Has a U-shaped cross section and has a cross section in the state of cutting the center hat, while both ends are fixed to the inner and outer center pillar side members 31 and 32 constituting the center pillar side member 30, respectively. The predetermined position is fixed to the chassis subframe 10 and the front side member 20 installed under the front side member 20, respectively.
여기서 상기 센터필러사이드멤버(30)의 내외측센터필러사이드멤버(31,32)도 단면이 상기 스테이(100)의 단면과 동일하게 형성되어 있다.Here, the inner and outer center pillar side members 31 and 32 of the center pillar side member 30 are also formed in the same cross section as that of the stay 100.
따라서 상기 전방사이드멤버(20)쪽에서 충격이 전달되어 섀시서브프레임(10)이 후방으로 밀리면 상기 센터필러사이드멤버(30)의 내외측센터필러사이드멤버 (31,32)에 의해 고정된 스테이(100)가 이를 지지해 주게 된다.Therefore, when the shock is transmitted from the front side member 20 and the chassis subframe 10 is pushed backward, the stay 100 is fixed by the inner and outer center pillar side members 31 and 32 of the center pillar side member 30. ) Will support it.
즉 상기 내외측센터필러사이드멤버(31,32)에 의해 고정된 스테이(100)의 양단이 고정되어 있으므로 충격흡수시 상기 스테이(100)가 회동운동을 하지 않게 된다.That is, since both ends of the stay 100 fixed by the inner and outer center pillar side members 31 and 32 are fixed, the stay 100 does not rotate when the shock is absorbed.
또한 단면의 높이를 높게 하여 충격흡수력을 높이는 효과가 있다.In addition, it is effective to increase the impact absorption by increasing the height of the cross section.
이상 설명한 바와 같이 본 고안에 의하면, 40% 오프셋충돌시 섀시보조프레임이 후방으로 밀릴 때 이를 효과적으로 지지할 수 있는 효과가 있다.As described above, according to the present invention, when the chassis auxiliary frame is pushed to the rear when 40% offset collision, there is an effect that can be effectively supported.
이상에서 본 고안의 구체적인 일 실시예를 상세히 설명하였으나, 본 고안은 이에 한정되는 것은 아니며, 이 분야의 통상의 지식을 가진 자라면 본 고안의 기술적 사상을 바탕으로 다양한 변경과 수정이 가능할 것이다.Although one specific embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and those skilled in the art may make various changes and modifications based on the technical idea of the present invention.
