차량용 범퍼 장치 {Bumper device for vehicle}Bumper device for vehicle}

본 발명은 차량용 범퍼 장치에 관한 것으로, 더욱 상세하게는 저속 충돌 성능을 유지하는 동시에 보행자 보호 성능을 향상시킬 수 있는 차량용 범퍼 장치에 관한 것이다.
The present invention relates to a vehicle bumper device, and more particularly, to a vehicle bumper device that can improve pedestrian protection while maintaining low speed collision performance.

일반적으로 자동차의 범퍼는 차량의 앞뒤에서 충돌 등으로 인해 외부로부터 자동차에 가해지는 충격 에너지를 흡수하여 차체 및 탑승자를 보호하기 위한 장치이다.In general, the bumper of the vehicle is a device for protecting the vehicle body and the occupant by absorbing the impact energy applied to the vehicle from the outside due to a collision, etc. in front and rear of the vehicle.

보통 자동차의 범퍼는 범퍼 커버가 차체의 외관을 이루고, 범퍼의 강성 및 충격 흡수의 기능을 위해 상기 범퍼 커버의 뒤에 차체에 고정된 범퍼 백빔이 설치되며, 상기 범퍼 백빔과 범퍼 커버 사이에 충돌 등으로 인해 외부로부터 자동차에 가해지는 충격 에너지를 흡수하기 위한 E/ABS가 설치된 구조를 갖는다.In general, a bumper of a vehicle has a bumper cover forming the exterior of a vehicle body, and a bumper back beam fixed to the vehicle body is installed behind the bumper cover to function as a rigidity and shock absorber of the bumper. Due to this structure, the E / ABS is installed to absorb the impact energy applied to the vehicle from the outside.

상기 E/ABS는 폼 구조물로서 스펀지와 같은 구조로 구비되고, 상기 범퍼 커버 또는 범퍼 백빔에 클립 등을 통해 고정된다.The E / ABS is provided as a foam structure in a sponge-like structure, and is fixed to the bumper cover or the bumper back beam through a clip or the like.

최근 자동차의 범퍼 장치 등에 관련하여 유럽의 자동차 관련 법규는 승객의 안전을 보호하는 단계를 넘어서 보행자 안전을 위한 범위로 확대되고 있으며, 이에 따라 차량의 범퍼 장치 또한 보행자 보호 성능을 고려한 수준의 상품성을 제공하도록 설계되고 있다.Recently, European automobile laws have been expanded to protect pedestrian safety beyond the protection of passengers, and thus, bumper devices of vehicles also provide a level of merchandise in consideration of pedestrian protection. It is designed to be.

도 1 내지 도 2에 도시된 바와 같이, 종래 기술에 따른 차량용 범퍼 장치는 차량의 저속 충돌시 타차량과의 오버라이드를 방지하기 위한 보강 부품으로 범퍼 백빔(1) 상단에 어퍼 레인포스(2)를 구성하고 있다.1 to 2, the vehicle bumper device according to the prior art is a reinforcement part for preventing the override with other vehicles in the low-speed collision of the vehicle as the upper rain force (2) on the top of the bumper back beam (1) It consists.

그러나, 이러한 어퍼 레인포스(2)는 보행자 충돌시 타격영역의 하나인 어퍼래그 영역에서 보행자에게 상해를 입히는 문제가 있다(도 3 참조).However, the upper rain force 2 has a problem of causing injury to pedestrians in the upper lag area, which is one of the hitting areas when pedestrians collide (see FIG. 3).

이에 따라, 차량용 범퍼는 저속 충돌시 타차량과의 오버라이드를 방지하는 동시에 보행자 보호 성능을 만족하기 위해 강하면서도 부드러운 성능을 가져야 하는 모순이 발생하게 된다.Accordingly, a bumper for a vehicle may have a contradiction in which a bumper for a vehicle should have a strong and smooth performance in order to prevent an override with another vehicle at the same time and to satisfy a pedestrian protection performance.

예컨대, 범퍼 장치의 설계시, 보행자 보호 성능의 저하를 방지하기 위해 상기의 어퍼 레인포스를 삭제해야 하는데, 이 경우 저속 충돌시 타차량과의 오버라이드가 발생하고 그에 따른 수리비가 증가하게 되는 문제점이 있다.For example, in the design of the bumper device, the upper rain force must be deleted to prevent the pedestrian protection performance from deteriorating. In this case, there is a problem in that an override with another vehicle occurs at a low speed collision and the repair cost increases accordingly. .

이와 같이 종래 기술에 따른 차량용 범퍼 장치는 저속 충돌 성능과 보행자 보호 성능을 동시에 유지하기 어려운 문제가 있으며, 그에 따라 디자인 자유도 및 패키지 레이아웃 측면에서 제약이 발생하게 된다.
As such, the bumper device for a vehicle according to the related art has a problem that it is difficult to simultaneously maintain a low-speed collision performance and a pedestrian protection performance, and thus, a limitation occurs in terms of design freedom and package layout.

본 발명은 상기와 같은 문제점을 해결하기 위해 발명한 것으로서, 저속 충돌 및 보행자 충돌 등의 충돌 조건에 따라 회전하면서 세워지거나 눕혀지는 어퍼 레인포스를 구성하여, 저속 충돌시에는 타차량과의 오버라이드를 방지하고 보행자 충돌시에는 타격영역의 차체 변형을 위한 공간을 확보함으로써, 저속 충돌 성능을 유지함과 동시에 보행자 보호 성능을 향상시킬 수 있도록 한 차량용 범퍼 장치를 제공하는데 그 목적이 있다.
The present invention has been invented to solve the above problems, and constitutes an upper rain force that is erected or lying down while rotating according to collision conditions such as low speed collision and pedestrian collision, and prevents override with other vehicles during low speed collision. The purpose of the present invention is to provide a bumper device for a vehicle that maintains a low speed collision performance and improves pedestrian protection while securing a space for deformation of the vehicle body in a pedestrian collision.

상기한 목적을 달성하기 위해 본 발명은, 범퍼 백빔 상부에 회전가능하게 설치된 어퍼 레인포스가 구성되어서, 저속 충돌시에는 하부의 힌지축을 중심으로 하여 위로 회전되어 세워지면서 타차량의 오버라이드를 방지하고, 보행자 충돌시에는 하부의 힌지축을 중심으로 하여 아래로 회전되어 눕혀지면서 차체 변형공간을 확보할 수 있도록 된 것을 특징으로 하는 차량용 범퍼 장치를 제공한다.In order to achieve the above object, the present invention, the upper reinforcement is rotatably installed on the bumper back-beam upper portion, in the case of a low-speed collision is rotated up around the lower hinge axis to prevent the override of other vehicles, In the case of a pedestrian collision, the vehicle is provided with a bumper device, which is configured to secure a vehicle deformation space while being rotated and laid down around a hinge axis of the lower portion.

바람직하게, 상기 어퍼 레인포스는 저속 충돌시 범퍼 백빔의 상부에 접촉되어 지지되는 스토퍼부와, 보행자 충돌시 E/ABS의 걸림단이 걸림 고정되는 가이드리브를 갖는 것을 특징으로 한다.Preferably, the upper reinforcement has a stopper portion which is in contact with and supported by the upper portion of the bumper back beam during low-speed collision, and a guide rib that locks the locking end of the E / ABS during pedestrian collision.

또한, 상기 어퍼 레인포스는 범퍼 백빔 상단의 로워 플레이트를 관통한 힌지축에 의해 관통되어 상기 로워 플레이트에 회전가능하게 결합된다.
In addition, the upper rain force is rotatably coupled to the lower plate through the hinge axis passing through the lower plate on the top of the bumper backbeam.

본 발명에 따른 차량용 범퍼 장치는 보행자 충돌시 어퍼 레인포스가 눕혀지면서 차체 변형공간을 확보하게 됨으로써 보행자 상해치를 감소시킬 수 있고, 또한 저속 충돌시 어퍼 레인포스가 세워지면서 타차량의 오버라이드를 방지함에 따라 수리비를 절감하는 등 저속 충돌 성능을 개선하는 효과를 얻을 수 있다.The bumper device for a vehicle according to the present invention can reduce the pedestrian injury by securing the vehicle deformation space while the upper rain force is laid down during a pedestrian collision, and also prevents the override of other vehicles while the upper rain force is raised during a low-speed collision. This can improve the low speed collision performance, such as reducing the repair cost.

아울러, 본 발명에 의하면 평상시 라디에이터의 유효 쿨링면적을 확보함에 따라 냉각성능을 향상시킬 수 있는 이점이 있다.
In addition, according to the present invention there is an advantage that can improve the cooling performance by ensuring the effective cooling area of the radiator.

본 발명은 저속 충돌 성능 및 보행자 보호 성능을 동시에 만족시킬 수 있는 차량용 범퍼 장치에 관한 것으로, 범퍼 백빔 상부에 회전가능한 구조의 어퍼 레인포스를 설치 구성하여서 저속 충돌시에는 타차량의 오버라이드를 방지하고 보행자 충돌시에는 충격 흡수를 위해 차체 변형공간을 확보할 수 있도록 한다.The present invention relates to a bumper device for a vehicle capable of satisfying low-speed collision performance and pedestrian protection at the same time. The upper rain force of a rotatable structure is installed on the bumper back beam to prevent override of other vehicles during low-speed collision and In the event of a collision, it is possible to secure the body deformation space for shock absorption.

이하, 첨부된 도면을 참조로 하여 본 발명의 바람직한 일 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 일 실시예에 따른 차량용 범퍼 장치는 범퍼 커버(10)와 범퍼 백빔(11), E/ABS(18)와 함께 상기 범퍼 백빔(11) 상부에 설치된 어퍼 레인포스(12)를 포함하여 구성된다(도 6 참조).A bumper device for a vehicle according to an embodiment of the present invention includes a bumper cover 10, a bumper back beam 11, and an upper rain force 12 installed on the bumper back beam 11 together with the E / ABS 18. Configured (see FIG. 6).

도 4 및 도 5에 도시된 바와 같이, 상기 어퍼 레인포스(12)는 범퍼 백빔(11)의 상단에 설치 고정된 로워 플레이트(16)에 힌지축(17)을 통해 회전가능하게 결합된다.As shown in Figures 4 and 5, the upper rain force 12 is rotatably coupled via a hinge shaft 17 to a lower plate 16 fixed to the top of the bumper backbeam 11.

다시 말해, 상기 어퍼 레인포스(12)는 범퍼 백빔(11) 상단의 로워 플레이트(16)를 관통한 힌지축(17)에 의해 관통되어 상기 로워 플레이트(16)에 회전가능하게 결합된다.In other words, the upper rain force 12 is rotatably coupled to the lower plate 16 through the hinge shaft 17 passing through the lower plate 16 on the top of the bumper backbeam 11.

즉, 상기 힌지축(17)은 로워 플레이트(16)와 이에 맞물린 어퍼 레인포스(12)를 동시에 관통하여서 상기 어퍼 레인포스(12)를 로워 플레이트(16)에 회전가능한 구조로 연결한다.That is, the hinge shaft 17 penetrates through the lower plate 16 and the upper rain force 12 engaged therewith, thereby connecting the upper rain force 12 to the lower plate 16 in a rotatable structure.

이렇게 범퍼 백빔(11) 상부에 힌지축(17)을 중심으로 회전가능하게 설치된 어퍼 레인포스(12)는, 저속 충돌시에는 하부의 힌지축(17)을 중심으로 하여 위로 회전되어 세워지면서 타차량의 오버라이드를 방지하고, 보행자 충돌시에는 하부의 힌지축(17)을 중심으로 하여 아래로 회전되어 눕혀지면서 차체의 변형을 위한 공간을 확보하게 된다.In this way, the upper rain force 12 is rotatably installed around the hinge shaft 17 on the upper part of the bumper back beam 11, and is rotated upwardly about the lower hinge shaft 17 in the case of a low speed collision. In order to prevent the override of the pedestrian collision, and rotated down around the hinge axis 17 of the lower side to secure a space for the deformation of the vehicle body.

이를 위하여 상기 어퍼 레인포스(12)는 상단의 가이드리브(14)와 하단의 스토퍼부(13)를 갖는 바람직한 형태로 구성된다.To this end, the upper rain force 12 is configured in a preferred form having a guide rib 14 at the upper end and a stopper portion 13 at the lower end.

구체적으로 살펴보면, 상기 어퍼 레인포스(12)는 타차량과의 저속 충돌시 범퍼 백빔(11)의 상부(즉, 로워 플레이트의 상면)에 접촉 및 지지되는 평평한 단면 형태의 스토퍼부(13)가 하단에 구비되고, 보행자 충돌시 충돌 에너지에 의해 변형되는 E/ABS(18)의 걸림단(19)이 걸림 고정되는 가이드리브(14)가 상단에 형성된다.Specifically, the upper reinforcement 12 has a flat cross-sectional stopper portion 13 contacting and supported by the upper portion of the bumper back beam 11 (ie, the upper surface of the lower plate) at a low speed collision with another vehicle. The guide rib 14 is provided on the upper end of the locking end 19 of the E / ABS 18, which is deformed by the collision energy during the pedestrian collision.

상기 스토퍼부(13)는 저속 충돌로 인해 어퍼 레인포스(12)가 도 7의 (a)와 같이 위로 회전될 시 범퍼 백빔(11)의 상단에 접촉되어 어퍼 레인포스(12)를 수직한 기립 상태로 세우고 지지하는 역할을 한다.The stopper part 13 stands on the upper rain force 12 vertically by contacting the upper end of the bumper back beam 11 when the upper rain force 12 is rotated upward as shown in FIG. It plays a role in establishing and supporting the state.

상기 가이드리브(14)는 보행자 충돌이 발생하는 경우 어퍼래그 영역에 가해지는 충격에 의해 E/ABS(18)가 변형되고 그에 따라 걸림단(19)이 어퍼 레인포스(12) 측으로 하강될 때 상기 걸림단(19)이 어퍼 레인포스(12)를 벗어나지 않도록 가이드하는 역할을 한다.The guide rib 14 is deformed when the E / ABS 18 is deformed by the impact applied to the upper lag area when a pedestrian collision occurs, and thus the locking end 19 is lowered to the upper rain force 12 side. The locking end 19 serves to guide the upper reinforcement 12 from leaving the upper reinforcement 12.

이에 의해 상기 어퍼 레인포스(12)는 가이드리브(14)에 고정된 걸림단(19)에 의해 도 7의 (b)와 같이 아래로 회전되어 차체 변형을 위한 공간을 확보함으로써 보행자의 상해를 감소시킬 수 있다.As a result, the upper reinforcement 12 is rotated downward by the locking end 19 fixed to the guide rib 14 as shown in FIG. You can.

이러한 어퍼 레인포스(12)는 범퍼 백빔(11) 상부에 그 길이방향을 따라 적어도 하나 이상으로 설치 구성될 수 있다.The upper rain force 12 may be installed at least one or more along the longitudinal direction of the bumper back beam (11).

또한, 상기 어퍼 레인포스(12)는 저속 충돌 시에만 도 8의 (b)와 같이 위로 세워지게 되고, 평상 시에는 도 8의 (a)와 같이 누워있음에 의해 라디에이터의 유효 냉각면적을 확보하여 냉각성능을 향상시킬 수 있다.In addition, the upper rain force 12 is erected up as shown in FIG. 8 (b) only at a low-speed collision, and normally, as shown in FIG. 8 (a), the effective cooling area of the radiator is secured. Cooling performance can be improved.

이상에서 설명한 바와 같이, 본 발명의 차량용 범퍼 장치는 저속 충돌 성능을 개선하여 타차량의 오버라이드를 방지할 수 있음은 물론 보행자 보호 성능을 향상시켜 보행자의 상해치를 줄일 수 있다.
As described above, the vehicle bumper device of the present invention can prevent the override of other vehicles by improving the low speed collision performance, and also improve the pedestrian protection performance, thereby reducing the injury value of the pedestrian.
