Description

자동차 후론트론지튜디널의 앞단부구조Front-end structure of the car front trophy

본 고안은 자동차 후론트론지튜디널의 앞단부구조에 관한 것으로, 보다 자세하게는 후론트 론지튜디널의 앞 단부면에 내부가 빈 사각뿔 형태의 크라쉬 캔(CRASH CAN)을 부착하여 정면충돌시 충돌 하중을 흡수하도록 한 자동차 후론트론지튜디널의 앞단부구조에 관한 것이다.The present invention relates to the front end structure of the front side of the front of the vehicle, more specifically to the front end of the front side of the front of the front of the front of the front of the crash cone (CRASH CAN) in the form of a hollow cone-shaped crash can load It's about the front end structure of the front-front of the automobile, which is absorbed.

후론트 론지튜디널(1)은 후방의 사이드셀(3)과 전방의 후론트 크로스멤버 후레임(4) 사이에 좌·우 양편으로 설치되어 엔진 및 변속기를 지지하는 후레임으로서, 상기 후방 사이드셀(3)과의 연결부위에는 상부로 굽은 만곡부(2)가 형성되어 있다.The front longi-terminal (1) is a frame that is installed between the rear side cell (3) at the rear and the front cross member frame (4) at the left and right to support the engine and the transmission, and the rear side cell (3). The curved part 2 bent upwards is formed in the connection part with a.

전방 충돌시 상기의 만곡부(2)는 중앙부위가 상부로 접혀지며 충동 하중을 흡수하는 완충역할을 한다.In the forward collision, the curved portion 2 has a central portion folded upward and serves as a buffer to absorb the impulsive load.

종래 자동차 후론트론지튜디널(1)의 앞 단부구조는 도 1에 도시한 바와 같이 횡단면이 ㄷ자 형태를 이루고 상하부의 선단(6)(6a)에는 소정의 폭을 갖는 접합플랜지(7)(7a)가 각각 길이 방향을 따라 일체로 직각되게 형성되어 있으며, 앞단부(5)에는 후론트크로스멤버 후레임(4)이 용접에 의해 부착되어 있다.As shown in FIG. 1, the front end structure of a conventional automobile front-side tunnel 1 has a cross-section having a C-shape and a joint flange 7 and 7a having a predetermined width at the top and bottom ends 6 and 6a. Are respectively formed at right angles to each other along the longitudinal direction, and the front cross member frame 4 is attached to the front end 5 by welding.

종래의 후론트 론지튜디널은 정면충돌시 일차적으로 후론트 범퍼에서 흡수하는 충돌 하중을 제외하고는 대부분의 충격하중을 만곡부에서 흡수하도록 하는 구조로 되어 있기 때문에 충돌하중이 크거나, 옵셋 충돌의 경우에는 엔진룸이 승객실안으로 밀려 탑승자가 상해를 입는 큰 문제점이 있다.Conventional Front Rondive Studio is designed to absorb most impact loads at the curved part except for the impact load absorbed by the front bumper during frontal collision, so the impact load is large or in the case of offset collision There is a big problem that the passengers are injured because the room is pushed into the passenger compartment.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 그 목적은 충돌하중이 큰 정면충돌사고나, 옵셋 충돌과 같은 위험한 전방충돌시 엔진룸이 승객실안으로 밀리는 것을 방지하기 위한 새로운 형태의 자동차 후론트론지튜디널의 앞단부구조를 제공하고자 하는 것이다.The present invention is to solve the above problems, the object is a new type of vehicle frontron for preventing the engine room from being pushed into the passenger compartment during dangerous frontal collisions, such as a frontal collision with a large impact load, offset offset collision This is to provide the front end structure of the tutorial.

이러한, 목적을 달성하기 위하여, 본 고안은 횡단면이 ㄷ자 형태를 이루면서 앞 단부선이 편평하고, 상하부의 선단에는 소정의 폭을 갖는 접합플랜지가 각각 길이 방향을 따라 일체로 직각되게 형성되어 있고, 상기 접합프랜지의 부착면에는 휀더에이프론 후론트판넬이 부착된 후론트 론지튜디널의 앞단부의 구조에 있어서, 전면부에 상하로 긴 장방형의 전면이 형성되고, 좌·우 양측면은 상기 전면의 양측 선단으로부터 점차 상하로 넓어지는 사리꼴 형상을 이루며 후방에 형성된 장방형의 부착면의 양측 선단에 연결되고, 상부와 저부에는 양선단이 평행한 장방형의 상면과 저면이 형성되며, 내부에는 충격완충공간이 형성되어 있는 크라쉬 캔(CRASH CAN)이 상기 후론트 론지튜디널의 앞단부에 부착되어 구성된 것을 특징으로 한다.In order to achieve the above object, the present invention has a cross-section forming a U-shape while the front end line is flat, and the upper and lower ends of the joint flanges each having a predetermined width are integrally formed at right angles along the longitudinal direction. In the structure of the front end of the front side of the front side of the frondron front panel with the fender apron front panel attached, the front and rear sides are formed with a long rectangular shape vertically, and the left and right sides are gradually formed from both front ends of the front surface. It is connected to both ends of the rectangular attachment surface formed at the rear and forms a trapezoidal shape that is widened up and down, and the upper and lower portions have a rectangular upper and lower sides parallel to each other, and an impact buffer space is formed therein. CRASH CAN is characterized in that it is attached to the front end of the front Rondition.

도 2는 도 1의 A를 확대시켜 본 고안에 따른 크라쉬 캔의 장착 상태를 나타내는 분해사시도도로서, 이에 도시한 바와 같이 횡단면이 ㄷ자 형태를 이루면서 상하부의 선단(6)(6a)에는 소정의 폭을 갖는 접합플랜지(7)(7a)가 각각 길이방향을 따라 일체로 직각되게 성형되어 있고, 상기 접합플랜지(7)(7a)의 부착면(8)(8a)에는 휀더에이프론 후론트판넬(9)이 부착되며, 후론트 론지튜디널(1)의 앞단부(5)에는 충돌 하중을 흡수할 수 있도록 내부가 중공된 구조의 육면체로 된 크라쉬 캔(CRASH CAN)(10)이 예컨대 용접에 의해 부착된다.FIG. 2 is an exploded perspective view showing a mounting state of the crash can according to the present invention by enlarging A of FIG. 1, and as shown in FIG. 1, a predetermined cross section of the upper and lower ends 6 and 6a is formed in a c-shape. Bonding flanges 7 and 7a having a width are formed integrally at right angles along the longitudinal direction, respectively, and are attached to the attachment surfaces 8 and 8a of the joining flanges 7 and 7a by a fender apron front panel ( 9) is attached, and the front end 5 of the front long terminal 1 has a hexahedral CRASH CAN 10 having a hollow structure so as to absorb a collision load. Is attached by.

상기의 크라쉬 캔(CRASH CAN)(10)은 전면부에 상하로 긴 장방형의 전면(11)이 형성되고, 좌·우 양측면(13)(14)은 상기 전면(11)의 양측 선단(11a)(11b)으로부터 점차 상하로 넓어지는 사리꼴 형상을 이루며 후방에 형성된 장방형의 부착면(12) 양측 선단(12a)(12b)에 연결되고, 상부와 저부에는 동일한 폭의 장방형으로 된 상면(15)과 저면(16)이 형성되며, 내부에는 충돌시 내부의 상하 및 좌우면(13a)(14a)(15a)(16a)이 안으로 접혀지도록 하여 충돌 하중을 흡수하는 충돌완충공간(17)이 형성된다.The above CRASH CAN 10 is formed with a front surface 11 of a rectangular shape that is long vertically up and down, and the left and right side surfaces 13 and 14 are both front ends 11a of the front surface 11a. A top surface 15 having a rectangular shape having a quadrilateral shape gradually extending upwardly and downwardly from the bottom face 11b and connected to both front ends 12a and 12b of a rectangular attachment surface 12 formed at the rear, and having the same width at the top and the bottom. ) And a bottom surface 16 are formed therein, and a collision buffer space 17 for absorbing a collision load is formed so that the upper and lower sides and the left and right sides 13a, 14a, 15a, and 16a of the inside are folded inward. do.

도 3은 본 고안에 따른 자동차 후론트론지튜디널의 앞 단부가 충돌로 인하여 변형되는 것을 나타내는 사시도로서, 이에 도시한 바와 같이 전방의 충돌물이 크라쉬 캔의 전면부에 충돌될 때 상·하면과 좌·우측면이 벨로우즈와 같이 주름이 잡히면 상기의 전면이 후방으로 후퇴된다.Figure 3 is a perspective view showing that the front end of the front front of the front of the vehicle according to the present invention is deformed due to a collision, as shown in the upper and lower and when the collision of the front hit the front of the crash can If the left and right sides are pleated like bellows, the front face is retracted backward.

본 고안은 후론트 범퍼와 후론트 론지튜디널의 만곡부사이에 설치되어 정면충돌이나 전방옵셋 충돌시 상기의 후론트 범퍼 이후로 전달되는 충돌하중을 엔진룸의 앞쪽에서 찌끄러지며 흡수 약화 시키므로 후방의 만곡부로 전달되는 충격이 상당 감소되어 엔진룸이 승객실 내부로 밀리는 것을 최소화할 수 있는 효과가 있다.This design is installed between the front bumper and the curved part of the front rondinal, and in the case of frontal collision or front offset collision, the impact load transmitted after the front bumper is crushed and absorbed from the front of the engine room and transmitted to the rear bent part. There is a significant reduction in the impact that can be minimized to push the engine room into the passenger compartment.
