Field of the Invention The present invention relates to a bumper structure for a vehicle, and more particularly, to a bumper structure for a vehicle, which can prevent a vehicle occupant from being damaged and parts thereof, .

종래에는 도 1에 도시된 바와같이 차량의 전방및 후방에 구비된 범퍼(1)는 그 내부에 충격흡수용 완충부재(2)를 삽입하고, 상기 완충부재(2)를 고정하며 차체와 연결된 범퍼 빔(3)으로 이루어져 타차량 또는 타설물과의 충돌시 범퍼(1)내부에 저장된 완충부재(2)가 그 충격을 흡수하도록 된 구조로 되어 있었다.Conventionally, as shown in FIG. 1, a bumper 1 provided at the front and rear of a vehicle has a shock absorbing member 2 inserted therein, a bumper 1 connected to a vehicle body by fixing the shock absorbing member 2, The shock absorbing member 2, which is made of the beam 3 and stored in the bumper 1 when the vehicle collides with the other vehicle, is made to absorb the impact.

이러한 종래의 범퍼는 타설물과의 충돌시 범퍼에 내장된 완충부재만이 그 충격력을 흡수할수 있는 구조로 충격량이 일정한도를 넘어서게되면 범퍼의 커버가 손상되고, 연속된 충격량이 곧바로 차체에 전달되어 운전자및 탑승자는 심한 충격을 받게되는 문제점이 있었다.Such a conventional bumper has a structure in which only the buffer member incorporated in the bumper can absorb the impact force when the bumper collides with the pierced object. When the amount of the impact exceeds a predetermined level, the cover of the bumper is damaged and a continuous impact amount is transmitted to the vehicle body There is a problem that the driver and the passenger are severely shocked.

상기와 같은 문제점을 해결하기 위한 본 발명은 차량이 타설물과의 충돌시 범퍼에서 받게되는 충격량을 단계적으로 흡수할수 있도록 하여 차량의 손상및 탑승자를 보다 안전하게 보호할 수 있도록 차량용 범퍼 구조물을 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention provides a bumper structure for a vehicle that can absorb an amount of an impact received from a bumper when the vehicle collides with a pile, and protect the passenger more safely. There is a purpose.

상기 목적을 달성하기 위한 본 발명은 차량의 전후방에 구비되며 내부에 충격흡수용 완충부재와, 상기 완충부재를 보호하고 차체와 연결된 빔으로 이루어진 범퍼에 있어서, 상기 빔은 일면이 상기 완충부재에 고정되고, 타면이 상하단에 지지면을 형성한 완충편과; 일면이 차체에 고정되고, 상기 완충편의 지지면 양쪽내측으로 슬라이드 되도록 타면의 상하단에 안내면이 형성된 흡수편과; 서로 결합된 상기 완충편과 상기 흡수편이, 서로 슬라이드 이동및 복원되도록 양쪽 내측면에 스프링이 삽입된 스프링 고정구가 각각 형성된 것을 특징으로 한다.According to an aspect of the present invention, there is provided a bumper provided at front and rear sides of a vehicle, the bumper including a shock absorbing cushion member and a beam connected to the vehicle body to protect the cushioning member. The beam is fixed to the cushioning member A cushion piece having a support surface formed on the upper and lower ends of the other surface; An absorbing piece having one side fixed to the vehicle body and a guide surface formed on the upper and lower ends of the other side so as to slide inside the both sides of the supporting surface; And the spring claws are formed on both inner side surfaces of the buffer piece and the absorbing piece, which are coupled to each other, so that the absorbing pieces are slidably moved and restored to each other.

이러한 특징으로 형성된 본 발명은 차량의 범퍼에 충격이 발생될때 그 충격량은 일차로 완충부재로 전달되고, 연이은 충격량은 완충부재와 연결된 완충편을 이동시키며, 이동되는 완충편은 차체와 고정된 흡수편과의 사이에 구비된 스프링의 압축으로 그 충격량을 감소시키는 구조로 되어있다.According to the present invention formed in this manner, when an impact is generated in a bumper of a vehicle, the amount of the impact is transmitted to the buffer member in a primary direction, the subsequent amount of impact moves the buffer piece connected to the buffer member, So that the amount of the impact is reduced.

차량의 전후방에는 충격보호용 범퍼(11)가 구비되며, 상기 범퍼(11)의 내부에는 충격흡수용 완충부재(12)와, 상기 완충부재(12)를 보호하고 차체(16)와 연결된 빔(13)으로 이루어져 있다. 그리고 상기 빔(13)은 각각 일면이 상기 완충부재(12)에 고정된 완충편(14)과, 일면이 차체(16)와 고정된 흡수편(15)으로 구성되고, 상기 완충편(14)의 타면은 상하단에 지지면(14a)(14b)이 형성되며, 상기 흡수편(15)의 타면은 상기 완충편(14)에 구비된 지지면(14a)(14b)의 양쪽내측으로 슬라이드 되도록 타면의 상하단에는 안내면(15a)(15b)이 형성되어 있다. 또한 상기 완충편(14)의 내면에는 다수개의 스프링 고정구(17)가 형성되고, 상기 흡수편(15)의 내면에는 상기 완충편(14)의 스프링 고정구(17)와 동일방향 동일위치로 다수개의 스프링 고정구(17)가 형성된 구조로 되어있다. 한편 상기 완충편(14)과 흡수편(15)의 양측단에는 보올트, 너트등의 고정구(18)에 의해 서로 체결되도록 체결브라켓(19)(20)이 구비된 구조로 되어있다.The bumper 11 is provided with shock absorbing cushioning members 12 and a beam 13 connected to the vehicle body 16 to protect the cushioning member 12 ). The beam 13 is composed of a cushioning piece 14 whose one surface is fixed to the cushioning member 12 and an absorbing piece 15 whose one surface is fixed to the vehicle body 16, And the other surface of the absorbent member 15 is slid toward the inside of both the support surfaces 14a and 14b of the cushioning member 14, And guide surfaces 15a and 15b are formed at the upper and lower ends of the guide surface 15a. A plurality of spring fixtures 17 are formed on the inner surface of the cushion piece 14 and a plurality of spring cushions 17 are formed on the inner surface of the cushion piece 14 at the same position in the same direction as the spring fixture 17 of the cushion piece 14. [ And a spring fixing hole 17 is formed. On both sides of the cushioning piece 14 and the absorbing piece 15, fastening brackets 19 and 20 are provided so as to be fastened to each other by fasteners 18 such as bolts and nuts.

이하, 본 발명에 따른 차량용 범퍼 구조물의 일 실시예를 첨부된 도면에 의거하여 상세히 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a vehicle bumper structure according to the present invention will be described in detail with reference to the accompanying drawings.

도 3에서와 같이, 차량의 범퍼(11)에 충격이 발생되었을 경우에는 그 충격량은 일차로 완충부재(12)로 전달되고, 연이은 충격량은 완충부재(12)와 연결된 완충편(14)에 전달된다. 이후 충격량을 전달받은 상기 완충편(14)은 차체(16)와 고정된 흡수편(15)의 지지로 상기 차체(16)로 슬라이드 이동되는데, 이때 상기 완충편(14)과 흡수편(15) 사이에 구비된 스프링(21)의 압축으로 그 충격량을 흡수하게 되는 것이다. 그리고 충격을 흡수하고 나면 스프링(21)의 복원력에 의해 상기 완충편(14)은 상기 흡수편(15)의 지지로 다시 복원되고, 복원되는 상기 완충편(14)에 의해 완충부재(12)가 복원되며, 연속해서 상기 완충부재(12)를 감싼 범퍼(11)커버가 원래의 상태로 복원되는 것이다.3, when an impact is generated in the bumper 11 of the vehicle, the impact amount is transmitted to the shock absorber 12 in a primary direction, and the subsequent shock amount is transmitted to the shock absorber 14 connected to the shock absorber 12 do. The cushion 14 is slid to the vehicle body 16 by the support of the absorbing piece 15 fixed to the vehicle body 16. The cushioning piece 14 and the absorbing piece 15 are slid, So that the amount of the impact is absorbed by the compression of the spring 21 provided between them. After absorbing the shock, the buffering piece 14 is restored to the support of the absorbing piece 15 by the restoring force of the spring 21, and the buffering member 12 is restored by the buffering piece 14 to be restored And the cover of the bumper 11 continuously wrapping the buffer member 12 is restored to its original state.

따라서 차량이 타설물과의 충돌시 범퍼에서 받게되는 충격량을 완충부재와, 서로 슬라이드 결합되는 완충편과 흡수편사이에서 스프링이 압축되며 단계적으로 충격량을 흡수할 수 있도록 하여 차량의 손상및 탑승자를 안전하게 보호할 수 있는 효과가 있다.Therefore, the amount of the shock that the vehicle receives at the bumper when the vehicle is impacted with the bumper is compressed between the shock absorbing member and the cushioning member and the absorbing member that are slidably engaged with each other. There is an effect that can protect.
