A vehicle bumper comprises: an upper back beam(100a) and a lower back beam(100b) divided in the top and bottom within the vehicle bumper inside; a spring(200) formed between both ends of the lower back beam and upper back beam; a stay(300) guiding the up and down motion of the lower back beam and upper back beam; and a bracket in which one side is positioned at the bumper cover and the other side is at the lower back beam and the other the upper back beam. The spring connects the upper back beam and lower back beam. The bracket move the upper back beam and the lower back beam up and down in the rear side collision.

Description

차량용 범퍼{Bumper for vehicle}Bumper for vehicle

본 발명은 차량용 범퍼에 관한 것으로서, 특히 후방 충돌 발생시 차량의 침입량을 줄여 차체의 손상을 최소화시키기 위한 차량용 범퍼에 관한 발명이다.The present invention relates to a vehicle bumper, and more particularly, to an automobile bumper for minimizing damage to a vehicle body by reducing an intrusion amount of a vehicle when a rear collision occurs.

일반적으로 자동차의 범퍼는 차체 전방 및 후방에 설치되어 차량 또는 외부 물체와 충돌시 충격을 흡수하여 차체가 받는 충격량을 감소시킴으로써 차체 및 탑승자를 보호할 뿐 아니라 후드 및 엔진룸에 장착된 엔진과 각종 구동기기 등을 보호하는 역할을 하는데, 각종 법규에 의한 충격요건에 만족되어야 함은 물론 소정의 강성과 신축성을 갖도록 설계되어야 한다.Generally, bumpers of automobiles are installed at the front and rear of the vehicle body to absorb shocks when colliding with the vehicle or external objects to reduce the amount of impact received by the vehicle body, thereby protecting the body and occupants, as well as the engines and various drives mounted in the hood and engine compartment. It serves to protect the equipment, etc., and it must be designed to have a certain rigidity and elasticity as well as satisfying the shock requirements according to various laws.

한편, 도 1에 도시된 바와 같이, 최근에는 전후방 충돌시 오버라이드 및 언더라이드 방지구조에 대해 지속적으로 요구하고 있는 바, 정상적인 차량 범퍼 테스트뿐만 아니라 SUV와 같은 지상고(地上高)가 높은 차량의 오버라이드 테스트도 시행하고 있는 실정이다.Meanwhile, as shown in FIG. 1, in recent years, there is a continuous demand for an override and underride prevention structure in front and rear collisions, as well as a normal vehicle bumper test, as well as an override test of a vehicle having a high ground height such as an SUV. It is also being implemented.

도 1 및 도 2는 종래의 차량용 범퍼에 관한 것으로, 도 1은 종래의 차량용 범퍼 충돌 테스트를 도시하는 도이며, 도 2는 종래의 차량용 범퍼를 도시하는 도이다.1 and 2 are related to a conventional vehicle bumper, Figure 1 is a diagram showing a conventional vehicle bumper crash test, Figure 2 is a diagram showing a conventional vehicle bumper.

종래의 차량용 범퍼는 도 2에 도시된 바와 같이, 범퍼커버(10)와, 상기 범퍼커버(10) 상단에 위치하는 리드패널(20)과, 상기 범퍼커버(10) 내측에 마련되어 충돌시 충격을 흡수하는 에너지옵져버(30)와, 상기 에너지옵져버(30)에 부착되어 있는 백빔(40)으로 이루어진다.Conventional vehicle bumpers are provided in the bumper cover 10, the lead panel 20 positioned on the bumper cover 10 and the bumper cover 10 inside the bumper cover 10, as shown in FIG. It consists of an energy observer 30 for absorbing and a back beam 40 attached to the energy observer 30.

이러한 차량용 범퍼의 후방 충돌 테스트시 오버라이드(over ride)인 경우에는 범퍼의 백빔(40)으로 충돌에너지의 흡수가 필요하지만, 평가장비(A)와 같이 높이가 상이하게 된 차량의 경우에는 대응할 수 없는 문제점이 있었다.In the case of an over ride during the rear collision test of the vehicle bumper, it is necessary to absorb collision energy by the back beam 40 of the bumper, but it is not possible to cope with a vehicle having a different height such as the evaluation equipment A. There was a problem.

또한, 차량 충돌시 오버라이드 및 언더라이드를 방지하기 위해 백빔의 높이를 증대시켜야 하지만 이러한 경우에는 범퍼의 크기 증대에 따른 중량증가로 인해 비용 상승 및 연비가 저하되는 문제점이 있었다.In addition, the height of the back beam should be increased in order to prevent override and underride in a vehicle crash, but in this case, there is a problem in that the cost increases and fuel economy is reduced due to the weight increase due to the increase in the size of the bumper.

본 발명은 차량용 범퍼에 관한 것으로서, 특히 후방 충돌 발생시 차량의 침입량을 줄여 차체의 손상을 최소화시켜 상품성을 향상시키는 동시에 운전자의 안전성을 증대시키기 위한 것을 목적으로 한다.BACKGROUND OF THE INVENTION 1.

Stay 300 for guiding the up and down movement of the back beam (100a) and the lower back beam (100b), one side is located in the bumper cover and the other side is a bracket which is located in the upper back beam (100a) and the lower back beam (100b) It consists of 400.

도 3 및 도 4에 도시된 바와 같이, 상방백빔(100a) 및 하방백빔(100b)은 차량의 범퍼커버 내측에 상하방향으로 분할되어 위치한다.As shown in FIGS. 3 and 4, the upper white beam 100a and the lower white beam 100b are divided in the up and down direction inside the bumper cover of the vehicle.

스프링(200)은 상방백빔(100a)과 하방백빔(100b)의 양끝단 사이에 마련되어 상기 상방백빔(100a)과 하방백빔(100b)을 상호 연결시켜주게 된다.The spring 200 is provided between both ends of the upper white beam 100a and the lower white beam 100b to interconnect the upper white beam 100a and the lower white beam 100b.

스테이(300)는 상방백빔(100a)과 하방백빔(100b)의 양끝단에 마련되어 상기 상방백빔(100a)과 하방백빔(100b)의 상하운동을 가이드 하게 된다.The stay 300 is provided at both ends of the upper white beam 100a and the lower white beam 100b to guide the vertical movement of the upper white beam 100a and the lower white beam 100b.

이때, 스테이(300)에는 가이드홀(310)이 형성되어 상방백빔(100a)과 하방백빔(100b)을 연결하는 스프링(200)이 상기 가이드홀(310)을 따라 이동할 수 있도록 하는 것이 바람직하다.At this time, it is preferable that the guide hole 310 is formed in the stay 300 so that the spring 200 connecting the upper white beam 100a and the lower white beam 100b can move along the guide hole 310.

브래킷(400)은 범퍼커버와 백빔을 연결하는 것으로, 일측은 상기 범퍼커버에 위치하게 되며, 타측은 상방백빔(100a)과 하방백빔(100b)에 위치하게 되어 후방 충돌시 상기 상방백빔(100a)과 하방백빔(100b)의 상하운동을 가능하게 한다.Bracket 400 is to connect the bumper cover and the back beam, one side is located in the bumper cover, the other side is located in the upper back beam (100a) and the lower back beam (100b) is the upper back beam (100a) in the rear collision It enables the vertical movement of the lower back beam 100b.

이하, 본 발명의 실시예를 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described.

도 3 및 도 4에 도시된 바와 같이, 차량의 범퍼커버 내측에 상하 분할되어 위치하는 상방백빔(100a)과 하방백빔(100b)의 양끝단에 스프링(200)을 통해 상호 연결되며, 상기 상방백빔(100a)과 하방백빔(100b) 양끝단에는 상기 스프링(200)이 이동할 수 있도록 가이드홀(310)이 형성된 스테이(300)가 마련되고, 상기 범퍼커버와 상기 상방백빔(100a) 및 하방백빔(100b)을 연결하는 브래킷(400)이 마련되어 후방 충돌시 상기 상방백빔(100a)과 하방백빔(100b)의 상하운동이 가능하게 한다.As shown in FIGS. 3 and 4, the upper and lower beams 100a and 100b, which are divided up and down inside the bumper cover of the vehicle, are connected to both ends of the upper and lower beams 100b by springs 200, respectively. Both ends 100a and 100b of the lower back beam 100b are provided with a stay 300 formed with a guide hole 310 to move the spring 200, and the bumper cover and the upper and lower back beams 100a and 100, respectively. A bracket 400 connecting 100b is provided to enable vertical movement of the upper white beam 100a and the lower white beam 100b during a rearward collision.

도 4 및 도 5에 도시된 바와 같이, 차량의 후방 충돌시 범퍼커버와 연결된 브래킷(400)에 힘이 전달되면 상방백빔(100a)과 하방백빔(100b) 방향으로 상기 브래킷(400)이 이동하게 되며, 이때 상기 브래킷(400)의 상하폭이 증대하게 되어 상기 상방백빔(100a)과 하방백빔(100b)을 상하방향으로 각각 이동시키게 된다.As shown in FIGS. 4 and 5, when a force is transmitted to the bracket 400 connected to the bumper cover during the rear collision of the vehicle, the bracket 400 moves in the direction of the upper back beam 100a and the lower back beam 100b. At this time, the vertical width of the bracket 400 is increased to move the upper white beam 100a and the lower white beam 100b in the vertical direction.

한편, 상방백빔(100a)과 하방백빔(100b) 양끝단에 위치하여 상기 상방백빔(100a)과 하방백빔(100b)을 연결하는 스프링(200)이 이완되어 스테이(300)에 형성된 가이드홀(310)을 따라 이동하게 되는데, 충돌 종료후에는 탄성력에 의해 상기 스프링(200)이 본래 위치로 이동하게 되어 상하방향으로 이동되었던 상기 상방백빔(100a)과 하방백빔(100b)이 정상 위치로 복원되도록 하는 것이다.On the other hand, the guide hole 310 formed in the stay 300 by relaxing the spring 200 is located at both ends of the upper white beam (100a) and the lower white beam (100b) connecting the upper white beam (100a) and the lower white beam (100b) After the collision, the spring 200 is moved to its original position by the elastic force so that the upper and lower back beams 100a and 100b, which have been moved up and down, are restored to their normal positions. will be.

상기와 같이 구성된 본 발명의 차량용 범퍼는 차량의 범퍼커버 내측에 상하 분할되어 위치하는 상방백빔과 하방백빔의 양끝단에 스프링을 통해 상호 연결되며, 상기 상방백빔과 하방백빔 양끝단에는 상기 스프링이 이동할 수 있도록 가이드홀이 형성된 스테이로 이루어져, 차체의 손상을 줄일 수 있게 하여 상품성을 향상시킬 수 있으며, 종래에는 충돌시 백빔에 힘이 전달되도록 하는 브래킷을 별도로 추가해야 했으나 본 발명에서는 상방백빔과 하방백빔에 적용되는 브래킷을 2개에서 1개로 축소하여 부품수 감소로 인해 원가를 절감시키는데 탁월한 이점을 가진 발명인 것이다.The bumper for a vehicle of the present invention configured as described above is connected to both ends of the upper and lower back beams which are split up and down inside the bumper cover of the vehicle through springs, and the spring moves to both ends of the upper and lower back beams. The guide hole is formed so that the damage to the body can be improved to improve the merchandise, conventionally had to add a bracket for transmitting the force to the back beam during a collision, but in the present invention, the upper and lower back beams It is an invention having an excellent advantage in reducing the cost by reducing the number of parts by reducing the bracket applied to two to one.
