Description
본 고안은 자동차의 사이드 멤버를 이루고 있는 본체와 보강 패널간의 강도 보강구조에 관한 것이다.The present invention relates to a strength reinforcement structure between the main body and the reinforcement panel forming the side member of the vehicle.
일반적으로, 자동차는 매우 고속으로 주행하는 장치이기 때문에 충돌 시의 탑승자 안전이 매우 크게 요구된다.In general, a vehicle is a device that travels at a very high speed, so occupant safety in the event of a crash is very high.
즉, 정면 또는 측면 충돌 시 자동차 내부에 탑승하고 있는 사람의 안전이 매우 중요하게 되기 때문에 자동차 설계시 바디의 충격에 대한 강성이 중요하게 된다.That is, since the safety of the person in the interior of the car is very important in the front or side collision, the rigidity against the impact of the body is important when designing the vehicle.
따라서, 자동차에는 정면 충돌 시의 충격에 의한 탑승자의 부상을 최소화하기 위하여 범퍼 어셈블리등이 설치되어 있는바, 이는 범퍼 어셈블리가 범퍼 스테이를 통해 엔진룸의 측면을 이루는 사이드 멤버에 연결되어 있게 된다.Accordingly, the vehicle is provided with a bumper assembly, etc. in order to minimize the injuries of the occupants due to the impact during the frontal collision, which is connected to the side member forming the side of the engine room through the bumper stay.
따라서 정면 충돌시 충격이 범퍼 어셈블리에 인가되면 이와 연결된 범퍼스테이와 사이드 멤버를 통해 충격이 분산 및 흡수되는 것이다.Therefore, when an impact is applied to the bumper assembly during frontal collision, the impact is dispersed and absorbed through the bumper stay and the side member connected thereto.
여기서, 사이드 멤버는 제3도 및 제4도에 도시된 바와 같이 ㄷ자형의 본체(11)와, 이 본체(11)의 상면에 결합되어 폐공간으로 형성하여 강성을 향상시키는 보강 패널(12)로 구성된다.Here, as shown in FIGS. 3 and 4, the side member is a c-shaped main body 11 and a reinforcement panel 12 that is coupled to the upper surface of the main body 11 to form a closed space to improve rigidity. It consists of.
즉, 보강 패널(12)와 본체(11)는 제4도에 도시된 바와 같이 본체(11)의 외측단을 보강 패널(12)의 측면에 폐공간을 형성하도록 용접 고정시켜 수직 및 정면 충격 흡수 능력을 향상시키는 것이다.That is, the reinforcing panel 12 and the main body 11 are welded and fixed to form a closed space on the side of the reinforcing panel 12, as shown in FIG. It is to improve your ability.
그러나, 이와같은 종래 사이드 멤버에 있어서는, 본체(11)의 외측면과 보강 패널(12)의 측면을 용접하는 과정에서 언더 컷이 발생됨으로써 상호간의 결합강도가 저하되는 요인이 되어왔다.However, in such a conventional side member, undercut is generated in the process of welding the outer surface of the main body 11 and the side surface of the reinforcement panel 12, and it has become a factor which reduces mutual bond strength.
따라서 가벼운 정면 충돌에 의해서도 사이드 멤버(10)에 전체적으로 균열 즉, 크랙이 유발되어 충격 흡수 능력이 저하되는 문제점이 발생된다.Therefore, even a light frontal impact causes cracking, that is, cracks, on the side member 10 as a whole.
본 고안은 이와같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본체와 보강 패널간의 결합강도를 향상시킴으로써 이에따른 충격 흡수 능력의 향상을 꾀할 수 있는 자동차의 사이드 멤버 보강구조를 제공함에 그 목적이 있다.The present invention has been made to solve such a conventional problem, and the object of the present invention is to provide a side member reinforcement structure of an automobile that can improve the shock absorbing ability by improving the bonding strength between the main body and the reinforcement panel. .
이와같은 목적을 달성하기 위하여 본 고안에 따른 사이드 멤버 보강구조는, ㄷ자형의 본체와, 이 본체에 폐공간을 이루도록 결합되는 보강 패널로 이루어진 자동차의 사이드 멤버에 있어서, 상기 본체와 상기 보강 패널간의 결합강도를 증가시키도록 자동차의 진행 방향을 기준으로 하여, 상기 보강 패널의 최선단부에 상기 본체의 내측 바닥면과 상,하 바닥면에 각각 용접 고정되는 제1,2경사부를 마련하여 된 것을 그 특징으로 한다.In order to achieve the above object, the side member reinforcement structure according to the present invention is a side member of a vehicle consisting of a U-shaped body and a reinforcement panel coupled to form a closed space in the body, between the body and the reinforcement panel. The first and second inclined portions which are welded and fixed to the inner bottom surface and the upper and lower bottom surfaces of the main body are provided at the uppermost end of the reinforcement panel to increase the bonding strength. It features.

제1도는 본 고안 사이드 멤버 보강구조를 도시한 사시도이고, 제2(a),(b),(c)도는 제1도의 A-A, B-B, C-C선 단면도이다.1 is a perspective view showing a side member reinforcing structure of the present invention, and Figs. 2 (a), (b) and (c) are cross-sectional views taken along line A-A, B-B and C-C of Fig. 1.
이에 도시된 바와 같이 본 고안 사이드 멤버(10)는 ㄷ자형 본체(11)와, 이 본체(11)와 동일 단면 형상을 가지며, 이에 용접 고정되어 폐단면을 형성하는 보강 패널(12)을 갖는다.As shown therein, the present invention side member 10 has a U-shaped body 11 and a reinforcement panel 12 having the same cross-sectional shape as the main body 11 and welded thereto to form a closed cross section.
이때 자동차의 진행 방향을 기준으로하여 보강 패널(12)의 선단부에는 하향 경사의 제1,2경사부(12a,12b)가 연장 형성되는 바, 이 제1,2경사부(12a,12b)는 본체(11)의 바닥면과 상,하 측면부를 따라 전체적으로 용접 고정된다.At this time, the first and second inclined portions 12a and 12b of downward inclination are extended to the front end portion of the reinforcement panel 12 based on the traveling direction of the vehicle. The first and second inclined portions 12a and 12b are formed. The welding is fixed as a whole along the bottom surface and the upper and lower side portions of the main body 11.
이와같은 본 고안은, 제2(a),(b),(c)도에 도시된 바와 같이 본체(11)와 결합되어 폐단면을 형성하는 보강 패널(12)의 용접부위가 크게 3부분으로 나뉘어 짐으로써 즉, 상호간의 용접 면적이 증대된 것이기 때문이 용접 과정에서 발생되는 언더 컷에 의해서도 충분한 결합 강도를 유지할 수 있게된다.The present invention, as shown in the second (a), (b), (c) as shown in the main body 11, the welded portion of the reinforcement panel 12 to form a closed cross-section is largely divided into three parts By being divided, that is, the increased welding area between each other, the sufficient bond strength can be maintained even by the undercut generated during the welding process.
따라서 정면 충돌시에도 충분한 강도를 유지할 수 있게되어 안정된 충격 흡수 능력을 발휘하게 된다.Therefore, sufficient strength can be maintained even in the case of frontal collision, thereby exhibiting a stable shock absorbing ability.
이상과 같은 본 고안은, 정면 충돌시에 보강 패널이 그 선단부에 형성된 제1,2경사부를 통해 본체에 용접 고정된 것이기 때문에 용접 강도를 증가시킬 수 있게되어 정면충격 흡수력이 향상되는 잇점이 있다.The present invention as described above has the advantage that the welding strength can be increased because the reinforcement panel is welded and fixed to the main body through the first and second inclined portions formed at the front end portion at the time of the frontal collision, and thus the frontal shock absorption power is improved.
