Description
본 고안은 차량의 전면에 형성하는 본넷트의 전방에 형성된 프레임에 취부되는 크로스멤버에 관한 것으로서, 특히 크로스멤버의 내부에 보강리브를 형성함으로써 차량의 정면충돌시 차체에 전달되는 충격에너지를 흡수할 수 있도록 하는 차량용 크로스멤버의 보강구조에 관한 것이다.The present invention relates to a cross member mounted to a frame formed in front of a bonnet formed on the front side of a vehicle. In particular, by forming a reinforcing rib inside the cross member, it is possible to absorb the impact energy transmitted to the vehicle body in front of the vehicle. It relates to a reinforcing structure of a vehicle cross member.
일반적으로 차량의 전면에는 제1도에서 도시되는 바와 같이 엔진부(1)가 형성되고, 상기 엔진부(1)를 보호하기 위해 전면 좌우측에는 프론트사이드패널(10)이 형성되며, 상기 프론트사이드패널(10)의 전면 일측에 형성된 프론트프레임(20) 일측면에는 용접에 의해 사이드패널(30)이 취부되어 있다.In general, an engine unit 1 is formed on the front surface of the vehicle as shown in FIG. 1, and front side panels 10 are formed on the front left and right sides to protect the engine unit 1. The side panel 30 is mounted to one side of the front frame 20 formed at one side of the front surface of the front surface 10 by welding.
여기에서 상기 사이드패널(30)의 일측에는 결합공(31)이 형성되어 크로스멤버(40)가 끼워서 결합되도록 형성되는 바, 상기 크로스멤버(40)는 전면에 형성되는 프론트크로스멤버(41)와 후면에 형성되는 리어크로스멤버(42)로 구성되어 상,하단부가 용접에 의해 접합되어 구비된 것이다.Here, the coupling member 31 is formed at one side of the side panel 30 so that the cross member 40 is inserted and coupled to the bar, and the cross member 40 is the front cross member 41 formed on the front surface. It is composed of a rear cross member 42 formed on the back, the upper and lower ends are provided by welding.
이러한 차량용 크로스멤버의 보강구조는 차량의 정면충돌시 상기 크로스멤버(40)를 형성하는 프론트크로스멤버(41)와 리어크로스멤버(42)가 충격에너지를 흡수하지 못하는 결점이 있다.The reinforcement structure of the vehicle cross member has a drawback that the front cross member 41 and the rear cross member 42 forming the cross member 40 do not absorb the impact energy during the frontal collision of the vehicle.
이는 크로스멤버(40)의 내부 공간부(43)에 차량의 충돌시 충격에너지를 흡수할 수 있는 보강재를 형성하지 못함으로써 차량의 정면충돌 또는 접촉사고시 크로스멤버(40)의 변형이 심하고, 이로 인해 발생되는 충격에너지를 크로스멤버(40)가 그대로 흡수하여 쉽게 실내쪽으로 침입하게 됨으로써 엔진부에 충격을 가하게 되어 화재의 위험이 있어 승원의 안전을 위협하는 문제점이 있었다.This is because the internal member 43 of the cross member 40 does not form a reinforcement material that absorbs the impact energy when the vehicle collides, so that the deformation of the cross member 40 is severe during a frontal collision or contact accident of the vehicle. The impact energy generated by the cross member 40 is absorbed as it is, and easily penetrates into the room, thereby causing an impact on the engine unit.
이에 본 고안은 상기와 같은 문제점을 보완하기 위해 크로스멤버를 형성하는 프론트크로스멤버와 리어크로스멤버가 접합된 내부 공간부에 별도의 보강리브를 형성함으로써 차량의 정면충돌시 충돌에너지를 효과적으로 흡수할 수 있도록 하여 차체의 변형을 방지함은 물론 승원의 안전을 향상시킬 수 있는 차량용 크로스멤버의 보강구조를 제공함에 그 목적이 있다.Therefore, the present invention can effectively absorb collision energy during frontal collision of the vehicle by forming a separate reinforcing rib in the inner space where the front cross member and the rear cross member are joined to form the cross member. The purpose of the present invention is to provide a reinforcing structure of a vehicle cross member that can prevent deformation of the vehicle body and improve safety of the crew.

이하, 첨부된 도면에 의하여 본 고안의 기술적 사상을 상세히 설명하면 다음과 같다.Hereinafter, the technical spirit of the present invention in detail with reference to the accompanying drawings.
본 고안의 차량용 크로스멤버의 보강구조는 제1도에서 도시된 바와 같이 차량의 전면에 엔진부(1)가 형성되고, 상기 엔진부(1)를 보호하기 위해 전면 좌우측에는 프론트사이드패널(10)이 형성되며, 상기 프론트사이드패널(10)의 전면 일측에는 프론트프레임(20)이 형성되되, 이 프론트프레임(20)의 일측면에는 용접에 의해 사이드패널(30)이 취부되고, 상기 사이드패널(30)의 일측에는 결합공(31)이 형성되어 크로스멤버(40)가 끼워서 결합되는 차체구조가 종래와 동일하나, 본 고안의 요지는 제3도와 제4도에서 도시되는 바와 같이 크로스멤버(40)를 형성하는 프론트크로스멤버(41)와 리어크로스멤버(42)의 상,하단부가 용접에 의해 접합되어 구비되고, 상기 크로스멤버(40)의 내측에 생기는 공간부(43)에 보강리브(50)의 선단부가 절곡연장되어 프론트크로스멤버(41)와 리어크로스멤버(42)의 외측면과 전면부에 부착됨을 그 기술적 구성상의 특징으로 한다.The reinforcement structure of the vehicle cross member of the present invention has an engine unit 1 formed on the front of the vehicle as shown in FIG. 1, and the front side panel 10 on the front left and right sides to protect the engine unit 1. Is formed, the front frame 20 is formed on one side of the front side of the front side panel 10, the side panel 30 is mounted on one side of the front frame 20 by welding, the side panel ( 30, one side of the coupling hole 31 is formed, the cross member 40 is fitted to the body structure is the same as the conventional, but the subject matter of the present invention as shown in the third and fourth cross member 40 The upper and lower ends of the front cross member 41 and the rear cross member 42 are formed by joining by welding, and the reinforcing rib 50 is provided in the space 43 formed inside the cross member 40. Front end member is bent to extend the front cross member (41) That attached to the outer surface of the front portion of the rear cross member (42) is characterized in that on the technical configuration.
여기에서 상기 보강리브(50)는 소정폭을 갖는 판재로서 선단부가 절곡되고 하단부 소정위치에 절곡부(51)가 형성되어 있는 바, 상기 선단부는 프론트크로스멤버(41)와 리어크로스멤버(42)가 용접되는 상단부에 접합되어 취부되고, 하단부는 용접에 의해 상기 프론트크로스멤버(41)와 리어크로스멤버(42)가 용접되는 하단부에 접합되어진다.Here, the reinforcing rib 50 is a plate having a predetermined width, the front end is bent and the bent portion 51 is formed at the lower end predetermined position, the front end member 41 and the rear cross member 42 Is joined to the upper end to be welded, and the lower end is joined to the lower end to which the front cross member 41 and the rear cross member 42 are welded by welding.
또한 상기 보강리브(50)의 하부쪽에 형성된 절곡부(51)는 차체 전방쪽으로 비드면으로 형성시키어 차량 정면충돌 및 추돌시 차체의 가장 취약한 부위에 대하여 효과적으로 충격에너지를 흡수하도록 되어 있다.In addition, the bent portion 51 formed at the lower side of the reinforcing rib 50 is formed in the bead surface toward the front of the vehicle body to effectively absorb the impact energy to the most fragile parts of the vehicle body during collision and collision of the front of the vehicle.
이와 같이 구성되는 본 고안은 차량의 정면충돌시 크로스멤버(40)에 충격에너지가 직접적으로 전달되어지게 된다.According to the present invention configured as described above, the impact energy is directly transmitted to the cross member 40 during the frontal collision of the vehicle.
이때 크로스멤버(40)에 전달되는 충돌에너지를 상기 크로스멤버(40)를 형성하는 프론트크로스멤버(41)와 리어크로스멤버(42)가 결합되어 형성되는 내부 공간부(43)에 취부되는 보강리브(50)가 충돌에너지를 흡수하도록 형성된 것이다.At this time, the reinforcement ribs are installed in the inner space 43 formed by combining the front cross member 41 and the rear cross member 42 which form the cross member 40 with the collision energy transmitted to the cross member 40. 50 is formed to absorb the collision energy.
따라서 이러한 본 고안은 차량의 정면충돌 또는 접촉사고시 크로스멤버(40)에 작용되는 하중이 효과적으로 분산되도록 함으로써 차체의 변형을 감소시키며 승원의 안전성이 향상되도록 하는 효과를 갖는다.Therefore, the present invention has the effect of reducing the deformation of the vehicle body and improving the safety of the occupants by effectively distributing the load applied to the cross member 40 in the front collision or contact accident of the vehicle.
이상에서 설명한 바와 같이 본 고안은 크로스 멤버를 형성하는 프론트크로스멤버와 리어크로스멤버가 접합된 내부 공간부에 별도의 보강리브를 형성함으로써 차량의 정면충돌시 충돌에너지를 효과적으로 흡수할 수 있도록 하여 차체의 변형을 방지함은 물론 엔진부에 가해지는 충격을 감소하고 승원의 안전을 향상시키도록 되어 있다.As described above, the present invention forms an additional reinforcing rib in an inner space where the front cross member and the rear cross member, which form a cross member, are joined to effectively absorb the collision energy during the frontal collision of the vehicle. In addition to preventing deformation, the impact on the engine portion is reduced and the safety of the crew is improved.
