Description
본 발명은 승용차의 앞쪽차체 본네트 하부쪽에 설치되는 샷건(Shot Gun) 차체구조에 관한 것으로, 특히 차량충돌 및 추돌시 흡수성능강화 및 보행자와의 충돌시 충돌에너지를 약화시키어 보행자를 보호할 수 있는 승용차용 이중 샷건 차체구조에 관한 것이다.The present invention relates to a structure of a shot gun body installed below the bonnet of the front body of a passenger car. In particular, a passenger car that can protect pedestrians by strengthening absorption performance during vehicle collision and collision and weakening collision energy during collision with a pedestrian. Dual shotgun body structure.
통상, 승용차의 앞차체 본네트의 하부쪽에는 엔진룸의 테두리 일부를 구성하는 샷건 차체구조가 설치되어 있는 바, 이 샷건 차체는 휠 에이프론 차체와 전방펜더 사이를 연결하면서 자체의 강성을 향상시키기 위해 그 단면을 폐단면으로 형성하도록 보강재가 부착되어 있다.In general, a shotgun body structure is formed at the lower part of the front body bonnet of the passenger car, which forms a part of the rim of the engine room. The shotgun body is connected between the wheel apron body and the front fender to improve its rigidity. The reinforcing material is attached so that the cross section may be formed into the closed cross section.
즉, 종래 승용차의 앞차체에 설치되는 샷건 차체구조를 도 3의 참조로 설명하면, 샷건 차체(101)에 휠 에이프론(104)이 부착되고, 이 휠 에이프론(104)의 대향된 아우트쪽에 공지의 전방펜더가 연결되며, 상기 샷건 차체(101)의 자유단 쪽에는 공지의 라지에타 그릴(106)의 지지대가 설치되어 있는데, 이 샷건 차체(101)의 강성을 강화하기 위해 보강브라켓트(102)로 상기 샷건 차체(101)의 단면을 폐단면으로 형성시킨 구조로 되어 있다.In other words, when the shotgun body structure installed in the front vehicle body of a conventional passenger car is described with reference to FIG. 3, the wheel apron 104 is attached to the shotgun body 101, and the wheel apron 104 is opposite to the outer side of the wheel apron 104. A known front fender is connected, and a support of a known radiator grill 106 is installed at the free end of the shotgun body 101. The reinforcing bracket 102 is used to reinforce the rigidity of the shotgun body 101. The cross section of the shotgun vehicle body 101 is formed in a closed cross section.
그러나 종래 이와 같은 샷건 차체구조는 폐단면을 형성시킴으로서 차체 강성을 강화시킨 잇점이 있으나, 불의의 사고로 충돌하는 보행자에 가해지는 충격력을 상대적으로 크게 작용하여 보행자 사고시 사고 위험율을 높이는 문제점이 있었으며, 또한 차량의 정면충돌시 차체의 축압축력이 낮아 탑승자 및 운전자의 상해치를 높게 하는 문제점도 지니고 있었다.However, the conventional shotgun body structure has the advantage of strengthening the body rigidity by forming a closed cross section, but has a problem of increasing the risk of accidents in pedestrian accidents by acting relatively large impact force on the pedestrians collided with an accident. When the frontal collision of the vehicle has a problem of increasing the injuries of the occupants and drivers because of the low axial compression force of the body.
이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 보행자와의 사고시 또는 차량정면 충돌시에 충돌하는 보행자의 충격에너지를 완화시키어 사고 상해치를 낮추면서 차체의 축압축력을 강화시켜 운전자 또는 탑승객의 상해치를 완화시킬 수 있는 승용차용 이중 샷건 차체구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above conventional problems, by reducing the impact energy of pedestrians colliding at the time of an accident with a pedestrian or a vehicle front collision to reduce the accident injury value to enhance the axial compression force of the vehicle body or the driver or An object of the present invention is to provide a dual shotgun body structure for a passenger car that can alleviate the injury to the passengers.

상기와 같은 목적을 달성하기 위한 본 발명은 ㄷ자형 샷건 차체에 길이 방향을 따라 동일한 길이로 연장 부착되는 보강브라켓트를 갖추어 폐단면을 이루는 샷건 차체구조에 있어서, 상기 보강 브라켓트는 샷건차체의 상부쪽으로 연장되어 벤딩부가 형성된 이중구조를 갖추도록 되어있다.In order to achieve the above object, the present invention has a reinforcing bracket which is attached to the U-shaped shotgun body in the same length along the longitudinal direction and forms a closed cross section, wherein the reinforcing bracket extends toward the upper portion of the shotgun body. It is intended to have a double structure formed with a bending portion.
이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명이 적용된 승용차용 앞쪽차체의 부분사시도이고, 도 2는 도 1에서 본네트가 설치된 상태를 가정한 Ⅰ-Ⅰ선 단면도로서, 충격이 가해질 때 샷건 차체의 이동상태를 나타낸 도면이다.1 is a partial perspective view of a front vehicle body to which the present invention is applied, and FIG. 2 is a cross-sectional view taken along line I-I assuming that a bonnet is installed in FIG. 1, and shows a moving state of the shotgun body when an impact is applied.
도면에 도시된 바와 같이 본 발명은 ㄷ자형 샷건 차체(1)에 길이방향을 따라 동일한 길이로 연장부착되는 보강브라켓트(2)를 갖추어 폐단면을 이루면서 휠 에이프런(4)에 연결되는 승용차용 샷건차체구조에 있어서, 상기 보강브라켓트(2)는 샷건 차체(1)의 상부쪽으로 연장되어 벤딩부(3)가 형성된 2단구조로 이루어진 것을 특징으로 하고 있다.As shown in the drawing, the present invention has a reinforcing bracket (2) which is attached to the U-shaped shotgun body (1) extending in the same length along the longitudinal direction, and is connected to the wheel apron (4) while forming a closed section. In the structure, the reinforcing bracket (2) is characterized in that it consists of a two-stage structure extending to the upper side of the shotgun vehicle body (1) formed with a bending portion (3).
즉, 상기 보강브라켓트(2)는 ㄷ자형 샷건 차체(1)의 개방부에 맞닿아 상부쪽으로 연장되면서 90°각도로 벤딩되는 벤딩부(3)를 갖추고 있으며, 이 보강브라켓트(2)의 벤딩부는 앞쪽 펜더(5)의 벤딩부(3a)가 보울트와 같은 체결수단을 이용하여 부착되어 있다.That is, the reinforcing bracket (2) is provided with a bending portion (3) which is bent at an angle of 90 degrees while contacting the opening of the U-shaped shotgun body (1) and extending upward, the bending portion of the reinforcing bracket (2) The bending part 3a of the front fender 5 is attached using fastening means, such as a bolt.
따라서, 본 발명에 따른 이중 샷건 차체구조는 앞쪽 차체의 축압축력을 향상시키면서 보행자와의 충돌시 보행자에 가해지는 충격력을 완화시킬 수 있는바, 우선 보행자와의 충돌시 상기 화살표 방향으로 충격이 가해지면 본네트(6)의 하부쪽에 설치되는 샷건 차체(1)의 보강 브라켓트(2)에 형성된 벤딩부(3)가 실선에서 점선의 위치로 휘어지면서 보행자에 가해지는 충돌 에너지를 완화시킴에 따라 상해치를 저감시키도록 되어 있는 반면, 차량의 정면 충돌의 경우에는 샷건 차체(1)의 기본 폐단면 위쪽으로 개단면이 더 추가적으로 형성됨에 따라 축압축력이 높아져서 운전자와 탑승객의 상해치를 완화시키는 잇점을 갖추게 된다.Therefore, the double shotgun body structure according to the present invention can mitigate the impact force applied to the pedestrian during the collision with the pedestrian while improving the axial compression force of the front body. As the bending part 3 formed in the reinforcing bracket 2 of the shotgun body 1 installed at the lower side of the bonnet 6 is bent to the dotted line position in the solid line, the injury energy is reduced by reducing the collision energy applied to the pedestrian. On the other hand, in the case of a frontal collision of the vehicle, as the opening section is further formed above the basic closed section of the shotgun body 1, the axial compression force is increased, which has the advantage of alleviating the injury of the driver and the passenger.
상기와 같이 본 발명은 승용차의 앞차체에 설치되는 샷건 차체를 이중구조로 형성시키어 차량 정면충돌시 탑승객과 운전자의 상해 충격력을 감소시킬 뿐만 아니라, 보행자와의 충돌시에도 보행자에 가해지는 충격력을 완화시키도록 되어 있다.As described above, the present invention forms a shotgun body installed in the front body of the passenger car in a dual structure to reduce the impact force of passengers and drivers in front of the vehicle, as well as to reduce the impact force applied to the pedestrians in the event of a collision with the pedestrian. It is supposed to be.
