차량용 범퍼 부착 구조{STRUCTURE OF COMBINING BUMPER FOR CAR}Bumper attachment structure for vehicle {STRUCTURE OF COMBINING BUMPER FOR CAR}

본 고안은 차량용 범퍼에 관한 것으로, 특히 범퍼와 차체를 스프링으로 연결하고, 상기 범퍼를 핸드브레이크와 링크를 사용하여 연결하며, 범퍼에 일측종단이 일체로 부착되어 타측이 차체에 관통되는 축을 유압실린더의 피스톤축으로 함으로써, 핸드브레이크를 당기면 범퍼가 차체와 붙도록 하고, 핸드브레이크를 풀면 범퍼가 차체로부터 스프링 길이만큼 이격되도록 하여, 충돌 시에 스프링 및 유압실린더에 의하여 충격이 흡수되도록 하는 차량용 범퍼부착 구조에 관한 것이다.The present invention relates to a vehicle bumper, and in particular, to connect the bumper and the vehicle body by a spring, and to connect the bumper using a hand brake and a link, one end is integrally attached to the bumper, the other side of the hydraulic cylinder through the shaft When the hand brake is pulled out, the bumper is attached to the body of the piston, and when the hand brake is released, the bumper is spaced apart from the body by the length of the spring, so that the shock is absorbed by the spring and the hydraulic cylinder in the event of a collision. It's about structure.

일반적으로, 차체의 최전방에는 범퍼가 부착되어 있어서, 충돌 시에 충격을 완화시키도록 하고 있으나, 상기한 범퍼가 흡수하는 충격력이 미약하므로 충돌 발생시에 충격력의 대부분이 차체로 인가되어 차량손상이 커지게 되거나 승차자의 부상이 심하게 되는 문제점이 있었다.In general, bumpers are attached to the front of the vehicle to mitigate impact during a collision. However, since the impact force absorbed by the bumper is weak, most of the impact force is applied to the vehicle when a collision occurs, causing damage to the vehicle. There was a problem that the injury of the occupant is severe.

상술한 바와 같은 문제점을 해결하기 위한 본 고안의 목적은 범퍼와 차체를 스프링으로 연결하고, 상기 범퍼를 핸드브레이크와 링크를 사용하여 연결하며, 범퍼에 일측종단이 일체로 부착되어 타측이 차체에 관통되는 축을 유압실린더의 피스톤축으로 함으로써, 핸드브레이크를 당기면 범퍼가 차체와 붙도록 하고, 핸드브레이크를 풀면 범퍼가 차체로부터 스프링 길이만큼 이격되도록 하여, 충돌 시에 스프링 및 유압실린더에 의하여 충격이 흡수되도록 하는 차량용 범퍼부착 구조를 제공하는 데 있다.An object of the present invention for solving the problems described above is to connect the bumper and the vehicle body by a spring, connect the bumper using a hand brake and a link, one end is integrally attached to the bumper and the other side penetrates the vehicle body When the shaft is used as the piston shaft of the hydraulic cylinder, when the hand brake is pulled, the bumper is attached to the body, and when the hand brake is released, the bumper is spaced apart from the body by the spring length, so that the impact is absorbed by the spring and the hydraulic cylinder in the event of a collision. The present invention provides a bumper attachment structure for a vehicle.

이와 같은 목적을 달성하기 위한 본 고안의 실시 예를 하기에서 도면을 참조하여 보다 상세하게 살펴본다.An embodiment of the present invention for achieving the above object will be described in more detail with reference to the accompanying drawings.

도 1은 본 고안에 따른 차량용 범퍼 부착구조를 나타내는 분리 사시도이다.1 is an exploded perspective view illustrating a bumper attachment structure for a vehicle according to the present invention.

본 고안에 따른 차량용 범퍼 부착구조는 차체(10) 전방에 소정크기의 범퍼(11)를 부착하고, 상기 범퍼(11)와 다른 범퍼(12)를 다수개의 스프링(14)으로 연결하고, 상기 차체(10) 및 범퍼(11)를 관통하는 링크(16)를 사용하여 상기 범퍼(12)와 핸드브레이크(도시하지 않음)를 연결하여 핸드브레이크를 풀면 범퍼(12)가 차체(10)와 이격되도록 하고 핸드브레이크를 당기면 범퍼(12)가 차체(10)에 붙도록 하고, 차체(10) 내측에는 소정 갯수의 유압실린더(20)를 부착하여 상기 유압실린더(20)의 피스톤축(22)을 차체(10)를 관통시켜 범퍼(11)에 일체로 부착하고, 상기 범퍼(12)가 다른 범퍼(11)와 이격되었을 경우 범퍼(12)의 부착상태를 보다 견고하게 하기 위하여 일측종단이 상기 범퍼(12)에 일체로 부착되어 선단부가 범퍼(12)의 전/후 이동에 따라 일체로 전/후 이동되는 다수개의 고정봉(24)을 상기 다른 범퍼(11)를 관통시켜 차체(10)에 일체로 고정한다.The bumper attachment structure for a vehicle according to the present invention attaches a bumper 11 of a predetermined size to the front of the vehicle body 10, connects the bumper 11 and another bumper 12 with a plurality of springs 14, and the vehicle body. The bumper 12 is spaced apart from the vehicle body 10 by connecting the bumper 12 and the hand brake (not shown) using the link 16 penetrating the 10 and the bumper 11 to release the hand brake. When the hand brake is pulled, the bumper 12 is attached to the vehicle body 10, and a predetermined number of hydraulic cylinders 20 are attached to the inside of the vehicle body 10 to move the piston shaft 22 of the hydraulic cylinder 20 to the vehicle body. One end is connected to the bumper 11 so as to be integrally attached to the bumper 11 and the bumper 12 is firmly attached to the bumper 11 when the bumper 12 is spaced apart from other bumpers 11. 12) is integrally attached to the plurality of end portions are moved forward / backward integrally in accordance with the front / rear movement of the bumper 12 The Ding Feng 24 by passing through the other bumper 11 is integrally fixed to the vehicle body (10).

한편, 상기한 구성에서 범퍼(12)에 장착된 고정봉(24)을 차체에 고정하는 구조는 해당업자라면 다수의 방법으로 실시 가능하겠으나, 본 고안의 실시 예에서는 바람직하게 상기 고정봉(24)을 직경이 다르게 이분형성하여, 일측고정봉(24a)은 상기 범퍼(12)에 부착하고 타측 고정봉(24b)은 차체(10)에 일체로 부착하여 직경이 작은 고정봉이 직경이 큰 고정봉 내로 삽입되도록 한것이다.On the other hand, the structure for fixing the fixing rod 24 mounted to the bumper 12 in the vehicle body in the above configuration can be implemented in a number of ways if the relevant person, the embodiment of the present invention preferably the fixing rod 24 By dividing the diameter into two parts, one fixing rod 24a is attached to the bumper 12 and the other fixing rod 24b is integrally attached to the vehicle body 10 so that the fixing rod having a small diameter is inserted into the fixing rod having a large diameter. To be inserted.

상기한 바와 같이 구성된 본 고안에 따른 범퍼 부착구조의 실시 예를 살펴보면, 우선, 주행을 하지 않고 주차하고 있을 경우 도 2에 나타내는 바와 같이 운전자가 핸드브레이크를 당기면 상기 핸드브레이크에 연결된 링크(도 1에 도시 ; 16)가 당겨지면서 범퍼(12)를 당기게 되어 범퍼(12)는 다른 범퍼(11)에 밀착이 된 상태를 유지하게 되고, 이에 따라 상기 범퍼(12)에 부착된 유압실린더(20)의 피스톤축(22)이 돌출된 상태를 유지하게 된다.Looking at the embodiment of the bumper attachment structure according to the present invention configured as described above, first, if the driver pulls the hand brake as shown in FIG. 2 when the car is parked without driving (see FIG. 1). As shown in FIG. 16, the bumper 12 is pulled while being pulled, so that the bumper 12 remains in close contact with the other bumper 11, and thus, the hydraulic cylinder 20 attached to the bumper 12 is maintained. The piston shaft 22 is maintained in a protruding state.

그리고, 운전자가 주행을 할려고 핸드브레이크를 풀게 되면, 도 3에 나타내는 바와 같이 상기 핸드브레이크에 연결된 링크(도 1에 도시 ; 16)의 당기는 힘이 제거되어 범퍼(12)는 스프링(14)의 원복력에 의하여 다른 범퍼(11)로부터 밀려나서 복수의 범퍼(12)(11)는 스프링(14)의 거리만큼 이격된 상태를 유지하게 되고, 이에 따라 고정봉(24)이 범퍼(12)와 함께 전방으로 당겨지게 되어 주행중 범퍼(12)가 상하로 유동되는 것을 방지한다.Then, when the driver releases the handbrake to drive, the pulling force of the link (shown in FIG. 1; 16) connected to the handbrake is removed as shown in FIG. The bumper 12 is pushed away from the other bumper 11 by the reinforcement force so that the plurality of bumpers 12 and 11 remain spaced apart by the distance of the springs 14, and thus the fixing rod 24 is together with the bumper 12. Pulled forward to prevent the bumper 12 from flowing up and down while driving.

이와 같은 상태로 주행을 하다가 충돌이 발생할 경우, 우선 스프링(14)에 의하여 충격력이 1차로 흡수되며, 그 충격력이 클 경우 내부범퍼(11)에 부착된 유압실린더(20)의 피스톤축(22)이 유압실린더(20)내로 밀리면서 충격력이 재 흡수되어 차체(10)에 전달되는 충격력은 상당히 감소하게 된다.If a collision occurs while driving in this state, first, the impact force is first absorbed by the spring 14, and when the impact force is large, the piston shaft 22 of the hydraulic cylinder 20 attached to the inner bumper 11 is applied. The impact force is reabsorbed while being pushed into the hydraulic cylinder 20, and the impact force transmitted to the vehicle body 10 is significantly reduced.

따라서, 본 고안에 따른 차량용 범퍼 부착구조에 의하면, 충돌 시에 스프링과 유압실린더에 의하여 충격력이 대폭 감소되므로 충돌로 인한 차량의 파손 및 승차자의 부상정도가 대폭 감소되는 효과가 있다.Therefore, according to the bumper attachment structure for a vehicle according to the present invention, since the impact force is greatly reduced by the spring and the hydraulic cylinder at the time of collision, the damage of the vehicle due to the collision and the degree of injury of the occupant are greatly reduced.
