Abstract

PURPOSE: Bumper face reinforcement structure is provided to reduce the cost and the weight without additional components, and to improve impact resistance. CONSTITUTION: Plural horizontal ribs(11) are arranged at a right angle in a bumper face(BF), and integrated with the inner side of the bumper face. Vertical ribs(12) connected to each other are contacted to the ends of the horizontal ribs. The connecting portion of the horizontal rib has a hollow(11a) with injecting gas at forming. The connecting portion is thinned to prevent the sink mark of the bumper face. The bumper face has full impact resistance against the collision by the horizontal ribs and the vertical ribs without additional reinforcement. The bumper face reduces the weight and the cost without using additional components, and improves productivity by reducing working process.

자동차 범퍼페이스의 보강구조Reinforcement structure of automobile bumper face

본 발명은 자동차 범퍼페이스의 보강구조에 관한 것으로서, 상세하게는 범퍼페이스의 내측으로 내충격성을 보강하는 수평리브와 수직리브를 형성함으로써 별도 부품의 절감 및 경량화를 이루도록 하는 자동차 범퍼페이스의 보강구조에 관한 것이다.The present invention relates to a reinforcing structure of an automobile bumper face, and more particularly, to a reinforcing structure of an automobile bumper face that forms horizontal ribs and vertical ribs that reinforce impact resistance inside the bumper face to reduce and reduce weight of separate parts. It is about.

일반적으로 차량의 범퍼페이스(BF ; Bumper Face)는 도 1에 예시한 바와 같이 차량의 전후에서 차체를 보호하기 위해 설치된 범퍼(B ; Bumper)의 외부를 이루는 부품이다.In general, a bumper face (BF) of a vehicle is a component that forms an exterior of a bumper B (Bumper) installed to protect a vehicle body before and after the vehicle, as illustrated in FIG. 1.

이와 같은 범퍼페이스(BF)는 도 1의 A-A선 단면으로 종래 범퍼(B)의 구성을 나타낸 도 4에 도시한 바와 같이 내측의 에너지업소버폼(20 ; Energy Absorber Foam)과 보강부재(30 ; Reinforcement)를 감싸는 형태로 결합되어 범퍼(B)를 구성한다.Such a bumper face (BF) is a cross-sectional view of the conventional bumper (B) in the cross-section AA line of Figure 1 as shown in Figure 4 the energy absorber foam (20; Energy Absorber Foam) and the reinforcement member (30; ) Is combined to form a wrapper to form a bumper (B).

따라서 외부의 충격이 범퍼페이스(BF)를 통하여 에너지업소버폼(20) 및 보강부재(30)로 전달되면서 충격흡수의 기능을 수행하는 것이다.Therefore, the external shock is transmitted to the energy absorber foam 20 and the reinforcing member 30 through the bumper face (BF) to perform the function of shock absorption.

그러나 상기한 바와 같은 종래 구조는 보강부재 등 별도의 부품의 사용으로 인하여 중량이 커지며 작업공수가 많아짐에 따라 원가상승의 요인이 되고 있어 차량의 경량화 및 경제성에 문제점이 있었다.However, the conventional structure as described above has a problem that the weight increases due to the use of a separate component such as a reinforcing member and the cost increases as the number of work is increased, there is a problem in the weight and economy of the vehicle.

따라서 본 발명은 상기한 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 별도 부품의 사용을 절감하고 중량 및 원가를 절감하면서도 충분한 내충격성을 구비할 수 있도록 한 자동차 범퍼페이스의 보강구조를 제공하는 데 있다.Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a reinforcement structure of an automobile bumper face that can provide sufficient impact resistance while reducing the use of separate parts and reducing weight and cost. There is.

상기한 목적을 이루기 위하여 본 발명은 차량의 범퍼(B) 외관을 이루는 범퍼페이스(BF) 구조에 있어서,In order to achieve the above object, the present invention provides a bumper face (BF) structure forming the exterior of a bumper (B) of a vehicle,

상기 범퍼페이스(BF)의 내측으로 직각방향 수평형성된 수평리브(11)를 다수개 형성하고 이러한 수평리브(11)의 단부를 서로 연결한 수직리브(12)를 형성하여 구성되는 것을 특징으로 하는 자동차 범퍼페이스의 보강구조를 제공한다.An automobile characterized in that it is formed by forming a plurality of horizontal ribs (11) formed at right angles to the inside of the bumper face (BF) and vertical ribs (12) connecting the ends of the horizontal ribs (11) to each other. Provides a reinforcement structure for the bumper face.

이하 첨부된 예시도면을 참조하여 본 발명의 바람직한 실시예를 보다 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 도 1의 A-A선 단면에 대한 본 발명의 구성을 나타낸 예시도로서, 도시한 바와 같이 본 발명은 범퍼페이스(BF)의 내측으로 직각방향 수평형성된 수평리브(11)를 다수개 형성하고, 이러한 수평리브(11)의 단부에는 서로 연결된 수직리브(12)를 형성하여 구성된다.Figure 2 is an exemplary view showing the configuration of the present invention for the cross-section line AA of Figure 1, as shown in the present invention to form a plurality of horizontal ribs 11 formed horizontally perpendicular to the inside of the bumper face (BF) The ends of the horizontal ribs 11 are formed by forming vertical ribs 12 connected to each other.

이때 상기 범퍼페이스(BF)의 내측면과 일체로 성형되어 접속 연결되는 수평리브(11)의 연결부에는 도 3에 도 2의 C부를 확대 도시한 바와 같이 중공부(11a)를 구비함이 바람직한 바, 이는 성형시 개스를 주입하여 형성하는 것이며 범퍼페이스에 싱크마크(Sink Mark)가 발생되는 것을 방지하고자 접속부 두께를 얇게 형성한 것이다.At this time, the connecting portion of the horizontal rib 11 which is integrally molded and connected to the inner surface of the bumper face (BF) is preferably provided with a hollow portion (11a) as shown in FIG. , Which is formed by injecting gas during molding and forming a thin connection portion to prevent a sink mark from occurring on the bumper face.

이와 같이 형성된 범퍼페이스(BF)는 별도의 보강부재를 사용하지 않아도 상기 수평리브(11) 및 수직리브(12)로 인하여 외부의 충돌에도 충분한 내충격성을 갖게 된다.The bumper face (BF) formed as described above has sufficient impact resistance against external impact due to the horizontal ribs 11 and the vertical ribs 12 without using a separate reinforcing member.

이상과 같이 구성된 본 발명은 범퍼의 내충격성을 유지하면서도 중량을 절감할 수 있어서 차량의 경량화에 기여하는 효과를 가져오게 되며, 별도의 부품을 사용치 않음으로써 원가절감을 이룰 수 있게 된다. 또한 작업공수가 절감되어 생산성 향상의 효과를 이룰 수 있다.The present invention configured as described above can reduce the weight while maintaining the impact resistance of the bumper to bring the effect of contributing to the weight reduction of the vehicle, it is possible to achieve cost savings by not using a separate component. In addition, labor savings can be achieved, thereby improving productivity.
