Description

차량 범퍼의 크래쉬 박스 보강 구조{A CRASH BOX REINFORCE STRUCTURE FOR VEHICLE'S BUMPER}Crash box reinforcement structure of vehicle bumper {A CRASH BOX REINFORCE STRUCTURE FOR VEHICLE'S BUMPER}

본 발명은 차량의 범퍼 크래쉬 박스에 관한 것으로, 보다 상세하게는 차량의 범퍼와 차체 프레임을 연결하는 크래쉬 박스의 내측으로 삽입 설치되어 차량 충돌시 크래쉬 박스의 변형을 방지하는 차량 범퍼의 크래쉬 박스 보강 구조에 관한 것이다. The present invention relates to a bumper crash box of a vehicle, and more particularly, a crash box reinforcement structure of a vehicle bumper that is inserted into an inner side of a crash box connecting a vehicle bumper and a vehicle frame to prevent deformation of the crash box during a vehicle crash. It is about.

일반적으로 차량 범퍼의 크래쉬 박스는 도 1a에 도시되어 있는 바와 같이, 일반적으로 자동차의 앞뒤에는 충돌 또는 추돌 사고시 차체에 가해지는 충격 에너지를 흡수하여 탑승자의 안전을 도모할 수 있도록 범퍼(2)가 설치된다. In general, as shown in FIG. 1A, the crash box of the vehicle bumper includes a bumper 2 installed at the front and rear of the vehicle so as to absorb the impact energy applied to the vehicle body in the event of a collision or crash, to promote the safety of the occupant. do.

상기 범퍼(2)는 차체에 볼트(B) 결합되는 범퍼 스테이(2a)와, 상기 범퍼 스테이(2a)의 끝부분에 용접되어 결합되는 범퍼빔(2b)과, 상기 범퍼 빔(2b)의 외측면에 부착되어 차체에 가해지는 충격에너지를 흡수하는 업소버(2c)와, 상기 업소버(2c)가 감싸지도록 차체에 설치되어 차량의 외측에 노출되는 범퍼 커버(2d) 등으로 구성된다. The bumper 2 includes a bumper stay 2a that is bolted to the vehicle body B, a bumper beam 2b that is welded to and coupled to an end of the bumper stay 2a, and an outside of the bumper beam 2b. And an absorber 2c attached to the side to absorb shock energy applied to the vehicle body, and a bumper cover 2d installed on the vehicle body so as to surround the absorber 2c and exposed to the outside of the vehicle.

한편, 상기 범퍼(2)와 차체 프레임 사이에는 저속 충돌시 충격을 흡수하여 차량의 손상을 최소화할 수 있도록 크래쉬 박스(6)가 설치된다. Meanwhile, a crash box 6 is installed between the bumper 2 and the vehicle body frame so as to absorb a shock during a low-speed collision and minimize damage to the vehicle.

도 1b는 크래쉬 박스의 형태를 나타내는 사시도로서, 범퍼를 구성하는 범퍼빔(2b)의 양단 후방으로 크래쉬 박스(6)가 설치되어 있고, 차체 프레임과는 볼트 결합됨을 나타내고 있다. FIG. 1B is a perspective view showing the shape of a crash box, in which a crash box 6 is provided behind both ends of the bumper beam 2b constituting the bumper, and is bolted to the vehicle body frame.

상기 크래쉬 박스(6)는 내부에 공간이 형성되어 있기 때문에, 외부에서 충돌에 의한 에너지가 인가될 때, 변형되면서 충격을 흡수한다. Since the crash box 6 has a space formed therein, when the energy due to the collision is applied from the outside, it is deformed and absorbs the shock.

상기와 같은 크래쉬 박스는 차량과 차량의 운전자에게 영향을 주지 않는 저속 충돌시에도 쉽게 변형되기 때문에 차량의 수리에 비용과 시간이 소모되는 문제점이 있었다. Since the crash box is easily deformed even at low speed collisions that do not affect the vehicle and the driver of the vehicle, there is a problem in that cost and time are consumed in repairing the vehicle.

본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 차량의 범퍼에 연결되는 크래쉬 박스의 내측으로 보강 부재를 추가하여 저속 충돌시에 크래쉬 박스의 변형이 발생되지 않도록 하는 차량 범퍼의 크래쉬 박스 보강 구조를 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, a crash box reinforcement structure of the bumper of the vehicle so that the deformation of the crash box does not occur during low-speed collision by adding a reinforcing member to the inside of the crash box connected to the bumper of the vehicle The purpose is to provide.

상기 목적을 달성하기 위해 본 발명 차량 범퍼의 크래쉬 박스 보강 구조는 차량 범퍼의 크래쉬 박스에 있어서, 크래쉬 박스의 차체 프레임 연결 부위 내측으로 설치되는 보강재를 포함한다. In order to achieve the above object, the crash box reinforcement structure of the vehicle bumper of the present invention includes a reinforcement that is installed inside the vehicle frame connection portion of the crash box in the crash box of the vehicle bumper.

상기 보강재는 플레이트 형태로 형성되는 보강 본체, 상기 보강 본체의 양단에 서로 평행하게 형성되는 결합단으로 구성된다. The reinforcing material is composed of a reinforcing body formed in the form of a plate, the coupling end formed in parallel to each other on both ends of the reinforcing body.

상기 결합단은 크래쉬 박스의 내측에 용접으로 결합된다. The coupling end is welded to the inside of the crash box.

상기와 같이 구성된 본 발명은, 차량의 범퍼에 연결되는 크래쉬 박스의 내측으로 보강 부재를 추가하여 차량과 운전자에게 영향을 주지 않는 저속 충돌시에는 크래쉬 박스에 변형이 발생되지 않는 효과가 있다. The present invention configured as described above has the effect that deformation does not occur in the crash box during a low-speed collision that does not affect the vehicle and the driver by adding a reinforcing member to the inside of the crash box connected to the bumper of the vehicle.

상기와 같이 구성되는 본 발명에 의한 차량 범퍼의 크래쉬 박스 보강 구조의 일실시예의 구성을 상세히 살펴보면 다음과 같다. Looking at the configuration of an embodiment of the crash box reinforcement structure of the vehicle bumper according to the present invention configured as described above in detail as follows.

도 2는 본 발명에 의한 차량 범퍼의 크래쉬 박스 보강 구조의 일 실시예의 구성을 나타내는 사시도로서, 금속 재질의 플레이트를 이용하여 보강재(100)를 형성한다. 플레이트의 중앙 부분은 보강 본체(120)로 사용하고, 보강 본체(120)의 양단을 동일 방향으로 절곡하여 결합단(140)을 형성하여, 보강재(100)는 'ㄷ' 형태의 단면을 갖도록 형성한다. Figure 2 is a perspective view showing the configuration of an embodiment of a crash box reinforcement structure of a vehicle bumper according to the present invention, to form a reinforcement 100 using a metal plate. The central portion of the plate is used as the reinforcing body 120, and both ends of the reinforcing body 120 is bent in the same direction to form a coupling end 140, the reinforcement 100 is formed to have a cross-section '' ' do.

보강 본체(120)의 폭은 보강재(100)가 결합되는 크래쉬 박스(6)의 내측의 폭과 동일하게 형성하여 보강재(100)를 크래쉬 박스(6)의 내부에 삽입했을 때, 보강재(100)를 구성하는 결합단(140)이 크래쉬 박스(6)의 내측면에 밀착되는 크기로 형성되는 것이 바람직하다. The width of the reinforcing body 120 is the same as the width of the inner side of the crash box 6 to which the reinforcing material 100 is coupled, when the reinforcing material 100 is inserted into the crash box 6, the reinforcing material 100 Coupling end 140 constituting the is preferably formed in a size close to the inner surface of the crash box (6).

결합단(140)에는 크래쉬 박스(6)와 차체 프레임이 결합될 때 사용하는 볼트가 결합될 수 있도록 웰드 너트(160)가 고정되는 것이 바람직하다. It is preferable that the weld nut 160 is fixed to the coupling end 140 so that the bolt used when the crash box 6 and the vehicle body frame are coupled to each other.

보강재(100)를 구성하는 결합단(140)은 크래쉬 박스(6)의 내측에 용접에 의해 결합된다.Coupling end 140 constituting the reinforcing material 100 is coupled to the inside of the crash box (6) by welding.

상기와 같이 구성된 본 발명에 의한 차량 범퍼의 크래쉬 박스 보강 구조의 일 실시예의 작용을 도 3은 참조하여 살펴보면 다음과 같다. Referring to Figure 3 with reference to the operation of the embodiment of the crash box reinforcement structure of the vehicle bumper according to the present invention configured as described above are as follows.

우선, 도 2에 도시되어 있는 바와 같이 구성된 보강재(100)를 도 3에 도시되 어 있는 바와 같이, 크래쉬 박스(6)의 내측으로 삽입한다. First, the reinforcement 100 configured as shown in FIG. 2 is inserted into the crash box 6, as shown in FIG.

크래쉬 박스(6)와 차체 프레임(미도시)은 볼트 결합되므로, 보강재(100)가 삽입된 후 크래쉬 박스(6)와 차체 프레임을 볼트에 의해 결합시키되, 볼트의 단부는 결합단(140)에 고정되어 있는 웰딩 너트(160)에 결합되도록 한다. Since the crash box 6 and the body frame (not shown) are bolted, the crash box 6 and the body frame are coupled by bolts after the reinforcement 100 is inserted, but the ends of the bolts are coupled to the coupling end 140. It is coupled to the welding nut 160 is fixed.

볼트가 고정된 후, 크래쉬 박스(6)와 차체 프레임 및 보강재는 용접에 의해 고정되도록 한다. After the bolt is fixed, the crash box 6 and the body frame and reinforcement are fixed by welding.

상기와 같이 보강재(100)가 크래쉬 박스(6)의 내부에 고정되면 차량이 저속으로 주행 도중 충돌하였을 경우 즉, 차량의 탑승자가 부상을 입지 않는 정도의 사고가 발생했을 경우 사고에 의해 발생된 충격량이 크래쉬 박스(6)에 인가되어도 보강재(100)에 의해 흡수되어 크래쉬 박스(6)의 변형이 발생하지 않게 된다.When the reinforcement 100 is fixed to the inside of the crash box 6 as described above, when the vehicle collides while driving at a low speed, that is, when an accident occurs in which the occupant of the vehicle is not injured, the amount of impact generated by the accident Even when applied to the crash box 6, it is absorbed by the reinforcing material 100 so that the deformation of the crash box 6 does not occur.
