Description
본 발명은 자동차 범퍼의 완충장치에 관한 것으로, 특히 충돌시 발생하는 충격을 다단계로 흡수하여 충격 완충능력을 향상시킬 수가 있는 범퍼의 완충장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorber of an automobile bumper, and more particularly, to a shock absorber of a bumper capable of improving shock shock absorbing capacity by absorbing a shock generated during a collision in multiple stages.
도 2 및 도 3은 종래의 범퍼의 실시예들을 보여주는 도면으로, 도 2는 종래의 범퍼의 한 가지 실시예를 보여주는 도 1의 A-A'선의 단면도이며, 도 3은 종래의 범퍼의 다른 실시예를 보여주는 종단면도이다.2 and 3 are views showing embodiments of a conventional bumper, Figure 2 is a cross-sectional view of the line AA 'of Figure 1 showing one embodiment of a conventional bumper, Figure 3 is another embodiment of a conventional bumper A longitudinal cross-sectional view showing an example.
도 2를 참고하면, 종래의 범퍼구조는, 범퍼커버(1)와, 이 범퍼커버(1)의 내측에 장착되는 업소버 폼(energy absorber foam)(2)과, 업소버 폼(2)의 내측에 고장력의 빔(3)이 장착되게 된다.Referring to FIG. 2, a conventional bumper structure includes a bumper cover 1, an absorber foam 2 mounted inside the bumper cover 1, and an inside of the absorber foam 2. The high tension beam 3 is mounted.
이와 같은 종래의 범퍼는 충격을 가해지게 되면, 업소버 폼(2)의 완충작용에 의하여 충격을 흡수하게 된다.When such a conventional bumper is subjected to an impact, the shock absorber is absorbed by the buffering action of the absorber foam 2.
그러나, 이와 같은 종래의 범퍼구조는 충격을 업소버 폼(2)에 의해서만 충격을 흡수되게 되므로, 충격흡수 능력이 떨어지게 된다. 따라서, 이와 같은 종래의 범퍼구조를 개선하여 다단계로 충격을 흡수하기 위한 범퍼 완충장치가 개시되어 있다.However, such a conventional bumper structure is to absorb the shock only by the absorber foam (2), so that the shock absorbing capacity is reduced. Therefore, a bumper shock absorber for absorbing a shock in multiple stages by improving such a conventional bumper structure is disclosed.
도 3에 도시된 바와 같이, 다단계로 충격을 흡수하기 위한 종래의 범퍼 완충장치는, 범퍼커버(11)의 내측에 설치되는 업소버 폼(12)의 내측에 충격을 1차로 흡수하는 충격흡수부재(13)와, 유압의 완충작용으로 충격을 2차로 흡수하는 유압 완충수단(14)과, 이 유압완충수단(14)에 의한 오일을 수거함과 함께 충격을 3차로 흡수하는 보강빔(15)을 순차적으로 설치하여 구성된다.As shown in FIG. 3, a conventional bumper shock absorber for absorbing a shock in a multi-stage includes a shock absorbing member that primarily absorbs a shock inside an absorber foam 12 installed inside the bumper cover 11. 13), the hydraulic shock absorbing means 14 for absorbing the shock secondly by the hydraulic shock absorbing action, and the reinforcing beam 15 for absorbing the shock in the third order while collecting the oil by the hydraulic shock absorbing means 14 sequentially. It is configured by installing.
상기 유압완충수단(15)은 충격 흡수부재(13)의 내측면에 고정되는 피스톤부(16)와, 상기 보강빔(15)의 외측면에 형성되어 피스톤부(16)가 결합되는 실린더부(17)와, 이 실린더부(17)의 내부에 충진되는 오일(18)과, 상기 보강빔(15)의 실린더부(17)의 연결부위에 설치되는 체크밸브(19)로 구성된다.The hydraulic shock absorber 15 is a piston portion 16 fixed to the inner surface of the shock absorbing member 13, and a cylinder portion formed on the outer surface of the reinforcing beam 15, the piston portion 16 is coupled ( 17, an oil 18 filled in the cylinder portion 17, and a check valve 19 provided at the connection portion of the cylinder portion 17 of the reinforcing beam 15.
이와 같이 구성된 종래의 범퍼 완충장치는, 외부로부터 충격이 가해지게 되면, 충격 흡수부재(13)에 의하여 1차적(A)으로 충격을 흡수하게 되며, 피스톤부(16)가 실린더부(17)를 따라 이동하여 오일(18)을 압축시켜 체크밸브(19)를 개방시킴으로써 2차적(B)으로 충격을 흡수하여, 보강빔(15)에 의하여 3차적(C)으로 충격을 흡수하게 되는 것이다.In the conventional bumper shock absorber configured as described above, when the shock is applied from the outside, the shock absorbing member 13 absorbs the shock primarily by the A, and the piston part 16 opens the cylinder part 17. By moving along and compressing the oil 18 to open the check valve 19 to absorb the impact in the secondary (B), the reinforcement beam 15 to absorb the impact in the tertiary (C).
그러나, 이와 같이 유체를 완충부재로서 사용하는 경우에는 극히 짧은 시간에 발생하게 되는 충돌 충격을 효과적으로 대처하기가 어렵다. 즉, 짧은 시간동안에 충돌이 일어나는 경우에는 유체 역시도 강체와 유사한 강성을 갖기 때문에 완충부재로서의 유체는 충분한 완충효과를 얻기가 어렵게 된다.However, when the fluid is used as the shock absorbing member in this way, it is difficult to effectively cope with the collision shock generated in an extremely short time. That is, when a collision occurs for a short time, the fluid also has a rigidity similar to that of a rigid body, so that the fluid as a buffer member becomes difficult to obtain a sufficient buffering effect.
본 발명은 상기의 결점을 해소하기 위한 것으로, 충돌시에 발생하는 충격력이 다단계로 분산하여 흡수하도록 하는 범퍼 완충장치를 제공하고자 한다.The present invention is to solve the above-mentioned drawbacks, and to provide a bumper shock absorber that allows the impact force generated during a collision is dispersed and absorbed in multiple stages.
이러한 본 발명은 충격흡수재가 구비된 범퍼커버와; 상기 충격흡수재의 양측에 구비되는 제1플레이트와; 일측이 상기 제1플레이트에 결합되며, 타측이 차체 사이드멤버의 측부에 장착된 브래킷에 고정되는 완충부재와; 상기 사이드멤버에 횡방향으로 장착된 크로스멤버와 대면하는 충격흡수재에는 상기 제1플레이트보다 돌출되게 구비되는 제2플레이트로써 달성된다.This invention is a bumper cover provided with a shock absorber; First plates provided on both sides of the shock absorber; A shock absorbing member having one side coupled to the first plate and the other side fixed to a bracket mounted to the side of the vehicle body side member; The shock absorber facing the cross member mounted laterally to the side member is achieved as a second plate provided to protrude more than the first plate.

도 4에 도시된 바와 같이, 본 발명의 범퍼 완충장치는, 충격흡수재(101)가 구비된 범퍼커버(100)와; 상기 충격흡수재(101)의 양측에 구비되는 제1플레이트(110)와; 일측이 상기 제1플레이트(110)에 결합되며, 타측이 차체 사이드멤버(120)의 측부에 장착된 브래킷(121)에 고정되는 완충부재(130)와; 상기 사이드멤버(120)에 횡방향으로 장착된 크로스멤버(140)와 대면하는 충격흡수재(101)에는 상기 제1플레이트(110)보다 돌출되게 구비되는 제2플레이트(150)로 구성되는 것을 특징으로 한다.As shown in Figure 4, the bumper shock absorber of the present invention, the bumper cover 100 is provided with a shock absorbing material (101); First plates 110 provided on both sides of the shock absorber 101; A buffer member 130 having one side coupled to the first plate 110 and the other side fixed to the bracket 121 mounted on the side of the vehicle side member 120; The shock absorber 101 facing the cross member 140 mounted to the side member 120 in the lateral direction is configured as a second plate 150 protruding from the first plate 110. do.
상기 충격흡수재(101)는 종래에 공지된 업소버 폼(energy absorber foam)이 사용되며, 그 후단에는 제1플레이트(110) 및 제2플레이트(150)가 장착되게 된다. 상기 제1플레이트(110)는 충격흡수재(101)의 양측에 대칭되게 장착되며, 상기 제2플레이트(150)는 중앙부에 장착된다. 도 4에 도시된 바와 같이, 상기 제2플레이트(150)는 상기 제1플레이트(110)보다 도면부호 d만큼 돌출되도록 한다.The shock absorber 101 is a conventionally known absorber foam (energy absorber foam) is used, the rear end of the first plate 110 and the second plate 150 is mounted. The first plate 110 is mounted symmetrically on both sides of the shock absorber 101, the second plate 150 is mounted in the central portion. As shown in FIG. 4, the second plate 150 protrudes by the reference numeral d from the first plate 110.
상기 완충부재(130)는 탄성력을 갖는 것으로, 코일스프링 또는 주름이 형성된 주름관이 사용될 수가 있다.The buffer member 130 has an elastic force, a coil spring or a corrugated pipe formed with corrugations may be used.
이와 같이 구성된 본 발명의 범퍼 완충장치의 충돌시 작용은 다음과 같다.The action at the time of the bumper shock absorber of the present invention configured as described above is as follows.
충돌이 발생하게 되면, 1차적으로 범퍼커버(100)에 취부된 충격흡수재(101)가 충격을 흡수하게 되며, 이와 동시에 완충부재(130)가 좌굴되면서 충격 에너지를 흡수하게 된다. 이때, 충격 에너지는 양측의 사이드멤버(120)에는 전달되지 않는 상태이다. 계속해서 완충부재(130)가 압축되면서 제2플레이트(150)가크로스멤버(140)에 접촉되면서 양측 사이드멤버(120)에 간접적으로 충격이 전달되게 되면서 2차적으로 충격 에너지가 사이드멤버(120)에 의해 흡수되게 되며, 최종적으로 양 측면에 설치된 제1플레이트(110)가 사이드멤버(120)에 접촉되어 충격이 가해지면서 충격 에너지를 흡수하게 된다.When a collision occurs, the shock absorber 101 mounted on the bumper cover 100 primarily absorbs the shock, and at the same time, the shock absorbing member 130 buckles to absorb the impact energy. At this time, the impact energy is not transmitted to the side members 120 on both sides. Subsequently, the shock absorbing member 130 is compressed and the second plate 150 contacts the cross member 140, thereby indirectly transmitting shock to both side members 120. It is absorbed by, and finally the first plate 110 is installed on both sides are in contact with the side member 120 to absorb the impact energy as the impact is applied.
이와 같은 본 발명의 범퍼 완충장치는 충돌이 발생하게 되면, 발생된 충격이 다단계로 분산되어 사이드멤버에 전달됨에 따라 충돌시간이 지연되게 되므로, 승객에게 전달되는 충격을 효과적으로 완화시킬 수가 있게 된다.Such a bumper shock absorber of the present invention, when a collision occurs, the impact time is delayed as the generated shock is distributed in multiple stages and transmitted to the side members, it is possible to effectively alleviate the shock delivered to the passenger.
이상과 같은 본 발명은 충돌이 발생하게 되면 충격을 다단계로 분산하여 사이드멤버에 전달하게 되므로 충돌 에너지를 효과적으로 흡수하여 승객에게 가해지는 충격을 최소화할 수 있는 효과가 있는 발명인 것이다.The present invention as described above is an invention having the effect of minimizing the impact on the passengers by absorbing the collision energy effectively because the impact is distributed to the side members when the impact occurs in multiple stages.
