Description
본 발명은 자동차 범퍼에 관한 것이고, 보다 상세하게는 설치 및 분리가 용이한 한편, 충돌 성능이 개선된 구조를 가지는 자동차 범퍼에 관한 것이다.The present invention relates to an automobile bumper, and more particularly, to an automobile bumper having a structure that is easy to install and remove and has improved crash performance.
통상적으로, 자동차의 범퍼는 차량의 주행시 자동차 또는 외부 물체와의 충돌시 그 충격을 어느 정도 흡수하여 차체에 충격량을 감소시켜, 차량 및 운전자 또는 차량 탑승자가 손상 또는 부상을 방지하고자 차량의 전방 및 후방에 통상 설치된다.Typically, the bumper of a vehicle absorbs the impact to some extent when the vehicle collides with the vehicle or an external object to reduce the amount of impact on the vehicle body, thereby preventing the vehicle and the driver or the occupant of the vehicle from being damaged or injured. It is usually installed in.
이러한 자동차의 범퍼는 크게 3부분으로 나누어지며, 범퍼 페이스는 차량의 가장 전방에 위치되어 외부에서 보이는 부분으로, 폴리프로필렌 플라스틱으로 통상 제조된다. 범퍼 페이스의 내측 구조물은 AZDEL(폴리프로필렌 + 강화 섬유)로 이루어진 범퍼 보강물(리인포스먼트)이며, 범퍼 페이스와 범퍼 보강물 사이에는 에너지 업소버 포옴(form)이 위치된다. 범퍼 페이스는 플라스틱 체결구로 고정되며, 범퍼 보강물은 나사부를 가지는 스테이에 체결되는 너트로 차체에 고정된다. 범퍼 페이스와 범퍼 보강물은 통상 에너지 업소버 포옴을 그 사이에 두고 브라켓을 통하여 나사 수단에 의해 서로 결합되고, 이러한 범퍼는 범퍼 보강물을 자동차의 하부 프레임에 연결된 범퍼 스테이에 볼트를 이용하여 고정함으로써 자동차에 장착된다.The bumper of such a vehicle is largely divided into three parts, and the bumper face is located at the front of the vehicle and is visible from the outside, and is usually made of polypropylene plastic. The inner structure of the bumper face is a bumper reinforcement (reinforcement) made of AZDEL (polypropylene + reinforcing fiber), and an energy absorber form is located between the bumper face and the bumper reinforcement. The bumper face is fixed with plastic fasteners, and the bumper reinforcement is fixed to the vehicle body with a nut fastened to the stay with the threaded portion. The bumper face and the bumper reinforcement are usually joined together by screw means via brackets with an energy absorber foam in between, and these bumpers are secured by bolting the bumper reinforcement to the bumper stays connected to the underframe of the car. Is mounted on.
도 1은 종래의 자동차 범퍼의 장착 구조를 도시한 단면도이고, 도 2는 도 1에 도시된 범퍼의 평면도이다.1 is a cross-sectional view showing a mounting structure of a conventional automobile bumper, Figure 2 is a plan view of the bumper shown in FIG.
도 1 및 도 2에 도시된 바와 같이, 범퍼 페이스(11)가 정면에 위치되고, 범퍼 페이스(11)의 바로 뒤에는 에너지 업소버 포옴(12)이 위치된다. 에너지 업소버 포옴(12)은 차체에 설치되는 보강물(13)에 설치되도록 다수의 설치용 돌출부(14)들을 가진다. 이러한 설치용 돌출부(14)들이 도 1에 도시된 바와 같이, 보강물(13)의 전면에 형성된 구멍에 삽입된 후에, 볼트와 같은 체결구가 체결됨으로써, 에너지 업소버 포옴(12)은 보강물(13)에 설치된다.As shown in FIGS. 1 and 2, the bumper face 11 is located in front, and immediately behind the bumper face 11 is an energy absorber foam 12. The energy absorber foam 12 has a plurality of mounting protrusions 14 to be installed in the reinforcement 13 installed in the vehicle body. After the installation protrusions 14 are inserted into the holes formed in the front surface of the reinforcement 13, as shown in FIG. 1, fasteners such as bolts are fastened, whereby the energy absorber foam 12 is reinforcement 13. It is installed in).
그러나, 상기된 바와 같은 종래의 자동차 범퍼는 차체에 설치될 때 부품수가 많기 때문에, 조립 공수가 많이 소요되고 또한 범퍼를 회수하기 위하여 차체로부터분리할 때 복잡한 과정을 거친다는 문제점이 있었다.However, since the conventional bumper as described above has a large number of parts when installed in the vehicle body, there is a problem in that a lot of assembly labor is required and a complicated process is performed when separating from the vehicle body to recover the bumper.
또한, 에너지 업소버 포옴을 사용함으로써, 범퍼의 중량이 크기 때문에 조립 및 분리가 곤란하다는 문제점이 있었다.In addition, by using the energy absorber foam, there is a problem that the assembly and separation is difficult because the weight of the bumper is large.
따라서, 본 발명의 목적은 보다 경량으로 형성되는 한편, 조립 및 분리가 용이하도록 적은 부품수를 가지며, 또한 자동차의 충돌 성능을 개선할 수 있는 자동차 범퍼를 제공하는데 있다.Accordingly, it is an object of the present invention to provide an automobile bumper which is formed at a lighter weight, has a smaller number of parts for easier assembly and disassembly, and can also improve the collision performance of an automobile.

(도면의 주요 부분에 대한 부호의 설명)(Explanation of symbols for the main parts of the drawing)
1 : 범퍼 페이스 2 : 가스 주입구1: bumper face 2: gas inlet
3 : 가스 통로 4 : 공동부3: gas passage 4: cavity part
5 : 수평 리브 6 : 수직 리브5: horizontal rib 6: vertical rib
상기된 바와 같은 목적은, 차체의 전면에 보강부재에 의해 설치되는 범퍼 페이스에 있어서, 상기 범퍼 페이스의 외부면에 다수 형성된 가스주입구에 연통되어 작동가스가 소통되게 가스통로가 내설되고 상기 가스통로를 통해 유입된 작동가스에 의해 형성된 공동부가 상기 범퍼 페이스 상측, 하측 및 후측에 절곡형성된 수평리브 및 수직리브 사이에 위치되어 상기 수평리브 및 수직리브의 싱크마크를 방지하게 구성함으로 인해 달성된다.As described above, in the bumper face installed by the reinforcing member on the front surface of the vehicle body, a gas passage is built in communication with a gas inlet formed in a plurality of outer surfaces of the bumper face so that a working gas can be communicated with the gas passage. A cavity formed by the working gas introduced therethrough is achieved between the horizontal ribs and the vertical ribs bent at the upper, lower and rear sides of the bumper face to prevent sink marks of the horizontal ribs and the vertical ribs.
이하, 본 발명의 바람직한 실시예를 명세서에 첨부된 도면을 참조하여 보다 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
도 3은 본 발명에 따른 자동차 범퍼의 장착 구조를 도시한 단면도이다.3 is a cross-sectional view showing a mounting structure of a vehicle bumper according to the present invention.
도 3에 도시된 바와 같이, 본 발명에 따른 자동차 범퍼는 이를 구성하는 범퍼 페이스(1)의 외부면에 다수의 가스 주입구(2)가 형성되며, 또한 상기 가스 주입구(2)에는 예를 들어, 질소 가스와 같은 작동가스가 통과하는 다수의 가스 통로(3)가 연통되어 형성된다. 상기와 같이 형성된 가스 주입구(2)로부터 범퍼 페이스(1) 내부에 충진되어 있는 성형재에 상기에 예를 든 질소가스를 유입시키면 가스압에 의해 순간적으로 공동부(4)가 형성되어, 자동차가 다른 물체와 충돌되었을 때, 가스압에 의하여 형성된 상기 공동부(4)에 의해 충격이 완충 및 흡수된다.As shown in FIG. 3, the automobile bumper according to the present invention has a plurality of gas inlets 2 formed on an outer surface of the bumper face 1 constituting the same, and also in the gas inlets 2, for example, A plurality of gas passages 3 through which working gases such as nitrogen gas pass are formed in communication. When the above-described nitrogen gas is introduced into the molding material filled in the bumper face 1 from the gas inlet 2 formed as described above, the cavity 4 is instantaneously formed by the gas pressure, so that the automobile is different. When collided with the object, the shock is absorbed and absorbed by the cavity 4 formed by the gas pressure.
한편, 본 발명에 따른 범퍼 페이스(1)의 강성을 보강하기 위해 이 범퍼 페이스(1)의 상측 및 하측에 각각 수평리브(5)가 형성되고, 후측에는 수직리브(6)가 상호 절곡연결 되며 내부에는 상기와 같이 형성된 공동부(4)가 상기 수평리브(5)와 수직리브(6) 사이에 공간을 형성하게 된다. 그리고, 상기와 같은 구조를 가지는 범퍼 페이스(1)는 차체에 설치된 보강물(도면에 도시되지 않음)에 설치된다.On the other hand, in order to reinforce the rigidity of the bumper face 1 according to the present invention, horizontal ribs 5 are formed on the upper side and the lower side of the bumper face 1, respectively, and the vertical ribs 6 are bent and connected to the rear side. The cavity 4 formed as described above forms a space between the horizontal rib 5 and the vertical rib 6. Then, the bumper face 1 having the structure as described above is installed in a reinforcement (not shown in the figure) provided in the vehicle body.
또한, 살두께가 각각 다른 범퍼 페이스(1), 수평리브(5) 및 수직리브(6) 사이에 접촉하여 위치하는 공동부(4)에 의해 상기 범퍼 페이스(1), 수평리브(5) 및 수직리브(6)에 성형시 발생되는 싱크마크(SINK MARK)의 발생이 방지된다.Further, the bumper face 1, the horizontal ribs 5, and the cavity 4 are positioned by contact between the bumper face 1, the horizontal ribs 5, and the vertical ribs 6 having different flesh thicknesses. Generation of sink marks generated during molding on the vertical ribs 6 is prevented.
이러한 구조를 가지는 본 발명에 따른 자동차 범퍼는 2.5MPH의 속도에서 충돌하였을 때, 만족할만한 충돌 성능을 보인다.An automobile bumper according to the present invention having such a structure shows satisfactory collision performance when collided at a speed of 2.5 MPH.
이상에서 상세히 설명한 바와 같이, 본 발명은 에너지 업소버 포옴이 사용되지 않으므로, 종래의 자동차 범퍼와 비교하여 범퍼의 중량이 현저하게 경량화 되고, 조립을 위한 부품수가 감소되므로, 차체에 대한 설치 및 분리가 용이하며, 또한 범퍼 페이스 내부의 공동부에 의하여 수평리브와 수직리브의 싱크마크를 방지할 수 있으며, 상기 공동부에 의해 완충작용도 할 수 있는 효과를 제공한다.As described in detail above, since the energy absorber foam is not used, the weight of the bumper is remarkably lighter and the number of parts for assembling is reduced compared to a conventional automobile bumper, so that installation and separation of the vehicle body are easy. In addition, by the cavity inside the bumper face, it is possible to prevent the sync mark of the horizontal ribs and the vertical ribs, and provides an effect that can also be a buffer effect by the cavity.
