Description
본 발명은 자동차의 승객 보호장치에 관한 것이다.The present invention relates to a passenger protection device of a motor vehicle.
일반적으로 자동차는 고속으로 주행하는 것이기 때문에 탑승객의 보호를 위한 각종 수단이 마련된다.In general, since the vehicle is traveling at a high speed, various means for protecting passengers are provided.
예컨대, 자동차의 전면과 후면에 범퍼(bumper)를 마련하여, 정면 및 후면 충돌사고시 충격력을 흡수함으로써 탑승객의 보호를 도모하고 있으며, 도어상에는 임팩트 빔을 마련하여 측면 충돌시 도어가 내부로 밀림에 의해 발생될 수 있는 탑승객의 상해를 저감하도록 하고 있는등 많은 탑승객 보호수단이 채용되고 있다.For example, bumpers are provided on the front and rear of the car to protect the passengers by absorbing impact forces in front and rear collisions, and impact beams are provided on the doors so that the doors are pushed into the interior during side impacts. Many passenger protection measures are employed, such as reducing the injuries of passengers that may occur.
이러한 보호 수단에 있어서도 가장 큰 역할을 하는 것이 자동차의 전면에 마련되는 범퍼이다.The biggest role in such protection means is the bumper provided on the front of the vehicle.
즉, 도 3에서와 같이, 엔진룸을 밀폐하고 있는 후드(hood;11)의 전면측 바디(body;10)상에는 범퍼 커버(bumper cover;20)가 위치되고, 이 범퍼 커버(20)는 사이드 프레임(side frame;30)에 연결된 범퍼 빔(40)에 결합된다.That is, as shown in Figure 3, a bumper cover 20 is located on the front body (10) of the hood (hood) 11 that seals the engine room, the bumper cover 20 is a side It is coupled to a bumper beam 40 connected to a side frame 30.
미설명부호(50)은 차체 패널이며, S는, 휠(W)과 차체 패널(50) 사이에 개재되어 주행시 상,하 방향으로의 진동을 흡수하는 현가장치의 하나인 스프링이다.Reference numeral 50 is a body panel, S is a spring that is interposed between the wheel (W) and the body panel 50, one of the suspension device that absorbs the vibration in the up and down direction when running.
이러한 구성을 갖는 종래 자동차는, 정면 충돌시 범퍼 커버(20)가 충격력을 흡수함과 동시에 범퍼 빔(40)을 통해 사이드 빔(30)에 충격력을 분산시켜 충격을 완화시킴으로써 탑승객을 보호하도록 하고 있다.In the conventional vehicle having such a configuration, the bumper cover 20 absorbs the impact force during the frontal collision, and simultaneously distributes the impact force to the side beam 30 through the bumper beam 40 to mitigate the impact to protect passengers. .
그러나 이러한 종래 자동차에 있어서는, 통상적으로 정면 충돌시 운전자가 급 브레이크 작동을 행하게 되는 바, 이에따라 전방측 차체는 관성력에 의해 하향되어진다.However, in such a conventional vehicle, the driver normally performs a quick brake operation during a frontal collision, so that the front body is lowered by the inertia force.
이와같이 차체가 하향함에 있어서는, 차체 높이가 상대적으로 높은 트럭등과 충돌이 발생될 때 트럭의 차체 하부로 후드(11) 상부면이 밀려들어가게 되고, 최종적으로 차 내부로 트럭 등의 대형차의 차체가 밀려듬으로써 탑승객에게 치명적인 상해를 가하는 문제점이 야기된다.In this way, when the body is lowered, when the collision occurs with a truck having a relatively high body height, the upper surface of the hood 11 is pushed into the lower body of the truck, and finally the body of a large vehicle such as a truck is pushed into the car. This causes the problem of fatal injury to the passengers.
이러한 문제점은 최근에 가장 큰 문제점을 대두되고 있으며, 이에따른 적절한 방비책이 요망되고 있는 실정이다.This problem has been raised the biggest problem in recent years, according to the situation that the appropriate defense measures are required.
본 발명은 이와같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 충돌사고시 차체의 전면측을 상승시킴으로써 트럭 등의 대형차와 충돌이 발생될 때 차체가 대형차의 하부로 유입되는 것을 억제하여 탑승객의 안전을 도모할 수 있는 자동차의 탑승객 보호장치를 제공함에 그 목적이 있다.The present invention was created to solve such a conventional problem, by raising the front side of the vehicle body in the event of a collision, when the collision with a large vehicle such as a truck is suppressed from flowing into the lower portion of the large vehicle to reduce the safety of the passengers The purpose is to provide a passenger protection device of the vehicle that can be planned.
상기한 목적을 달성하기 위하여 본 발명은, 범퍼 빔을 통해 사이드 프레임상에 고정 설치되는 범퍼 커버와; 양단이 상,하 지지판에 의해 차체 패널과 휠 구동축상에 결합되며, 차체의 상,하 진동을 흡수하는 서스펜션 스프링과; 상기 범퍼 커버와 서스펜션 스프링의 상단 사이에 개재되어 충돌시 서스펜션 스프링을 가압함과 동시에 범퍼측 바디를 상승시키는 전방 차체 상승수단;으로 구성된 것을 그 특징으로 한다.In order to achieve the above object, the present invention includes a bumper cover fixedly installed on a side frame through a bumper beam; A suspension spring coupled to the vehicle body panel and the wheel driving shaft by upper and lower support plates, the suspension spring absorbing vibration of the vehicle body; And a front vehicle body lifting means interposed between the bumper cover and the upper end of the suspension spring to pressurize the suspension spring and raise the bumper side body at the time of collision.

도 1 및 도 2에서와 같이 본 발명은, 범퍼 빔(bumper beam;40)을 통해 사이드 프레임(side frame;30)상에 고정 설치되는 범퍼 커버(bumper cover;20)를 구비한다.As shown in FIGS. 1 and 2, the present invention includes a bumper cover 20 fixedly installed on a side frame 30 through a bumper beam 40.
그리고 휠(W) 구동축(3)과 바디(10) 즉 차체 패널(50)에 양단이 결합됨으로써 주행과정에서의 상,하 진동을 흡수하여 승차감을 향상시키는 서스펜션 스프링(S)을 구비한다.And both ends are coupled to the wheel (W) drive shaft 3 and the body 10, that is, the vehicle body panel 50 is provided with a suspension spring (S) for absorbing the up and down vibration during the driving process to improve the riding comfort.
즉, 서스펜션 스프링(S)은 상,하 지지판(1,2)을 통해 차체 패널(50)과 구동축(3)상에 개재됨으로써 상,하 진동을 흡수하게 되는 것이다.That is, the suspension spring (S) is absorbed up and down vibration by being interposed on the vehicle body panel 50 and the drive shaft (3) through the upper and lower support plates (1, 2).
이때 전술한 범퍼 커버(20)와 서스펜션 스프링(S)에는 본 발명의 특징적인 요소를 갖고 있는 것으로서, 충돌시 서스펜션 스프링(S)을 가압하여, 범퍼 커버(20)측 바디(10)를 상승시키는 전방 차체 상승수단(100)이 마련된다.At this time, the above-mentioned bumper cover 20 and the suspension spring (S) as having a characteristic element of the present invention, by pressing the suspension spring (S) during the collision, which raises the body 10 side of the bumper cover 20 The front vehicle body lifting means 100 is provided.
이러한 전방 차체 상승수단(100)의 상세한 구조를 보면, 크게 회전 레버(110)와 연결 레버(120)로 이루어진다.Looking at the detailed structure of the front vehicle body lifting means 100, it consists largely of the rotary lever 110 and the connecting lever 120.
회전 레버(110)는, 대략 중심면이 사이드 프레임(30)상에 회전 가능하게 힌지 결합되는 것으로서, 일단은 서스펜션 스프링(S)의 상단에 즉, 서스펜션 스프링(S)의 상면을 지지하고 있는 상부 지지판(1)의 상면에 개재된다.Rotation lever 110, the center surface is rotatably hinged on the side frame 30, one end is the upper end of the suspension spring (S), that is, the upper part supporting the upper surface of the suspension spring (S) It is interposed on the upper surface of the support plate 1.
그리고 이 회전 레버(110)의 타단은 사이드 프레임(20)에 힌지 결합된 부위를 중심으로 하여 상부 방향으로 소정각도 경사지게 연장 형성된다.And the other end of the rotary lever 110 is formed to extend inclined a predetermined angle in the upper direction with respect to the portion hinged to the side frame 20.
연결 레버(120)는, 일단이 범퍼 빔(40)의 내측면에 고정되는 것으로서, 타단은 전술한 회전 레버(110)의 타단에 회전 가능하게 힌지 결합된다.The connecting lever 120, one end is fixed to the inner surface of the bumper beam 40, the other end is rotatably hinged to the other end of the rotary lever 110 described above.
이와같이 구성된 본 발명은, 주행중에 정면 충돌이 발생하게 되면, 그 충격력은 범퍼 커버(20)를 통해 범퍼 빔(40)으로 전달된다.According to the present invention configured as described above, when a frontal collision occurs while driving, the impact force is transmitted to the bumper beam 40 through the bumper cover 20.
동시에 범퍼 빔(40)에 일단이 결합된 연결 레버(120)로 충격력이 전달되면서, 연결 레버(120)는 후방으로 이동되고, 이에따라 연결 레버(120)의 타단과 결합된 회전 레버(110)가 사이드 프레임(30)에 힌지 결합된 부위를 중심으로 하여 시계 방향으로 회전한다.At the same time, as the impact force is transmitted to the connection lever 120, one end of which is coupled to the bumper beam 40, the connection lever 120 is moved to the rear, whereby the rotary lever 110 coupled with the other end of the connection lever 120 is It rotates in a clockwise direction about a hinged portion of the side frame 30.
이와같이 회전 레버(110)가 시계 방향으로 회전하게 되면, 이 회전 레버(110)의 일단이 서스펜션 스프링(S)을 지면측으로 가압하여 서스펜션 스프링(S)을 압축함과 동시에 상기 서스펜션 스프링(S)의 압축력과 동일한 반작용(힘)이 상방 즉 차체 패널(50)에 작용함으로써 전방측 바디(10)가 상승하게 되며, 상기 전방측 바디(10)의 상승높이는 종래의 것보다 회전 레버(110)의 서스펜션 스프링(S)의 압축력만큼 증대되는 것이다.When the rotation lever 110 rotates in the clockwise manner as described above, one end of the rotation lever 110 presses the suspension spring S toward the ground to compress the suspension spring S and at the same time the A reaction (force) equal to the compressive force acts upward, i.e., on the vehicle body panel 50, so that the front body 10 rises, and the lift height of the front body 10 is higher than that of the conventional suspension of the rotary lever 110. It is increased by the compression force of the spring (S).
따라서 트럭등 대형차와 충돌이 발생될 때 급 브레이크 작동에 의해 전방측 바디(10)가 하향하는 것이 방지되어 차체가 대형차의 바디 하부로 유입됨에 의한 탑승객의 상해가 방지되는 것이다.Therefore, when a collision with a large vehicle such as a truck occurs, the front body 10 is prevented from descending by the rapid brake operation, thereby preventing injuries of passengers due to the inflow of the vehicle body under the body of the large vehicle.
한편, 상술한 동작에 의해 범퍼 커버(20)로 부터의 충격력이 범퍼 빔(40)을 통해 사이드 프레임(30)으로 고르게 전달됨으로써 전체적으로 고른 충격력 분포에 따른 완충효과를 배가시킬 수 있게된다.On the other hand, the impact force from the bumper cover 20 by the above-described operation is evenly transmitted to the side frame 30 through the bumper beam 40, it is possible to double the buffer effect according to the even impact force distribution as a whole.
이상과 같이 본 발명은, 정면 충돌시 전방 차체 상승수단을 통해 전방측 바디가 반작용에 의하여 상승됨으로써 대형차와의 충돌시 대형차의 바디 하부로 차체가 유입되는 것이 억제되어 탑승객의 안전을 도모할 수 있는 이점이 있다.As described above, according to the present invention, the front body is lifted by the reaction through the front body riser in the case of a frontal collision, so that the body is prevented from flowing into the lower body of the large vehicle when colliding with the large vehicle. There is an advantage.
또한 충격력이 범퍼 커버와 범퍼 빔 및 사이드 프레임으로 고르게 분포되어 흡수됨으로써 완충 효과를 상승시킬 수 있는 이점이 있다.In addition, the impact force is evenly distributed and absorbed into the bumper cover, the bumper beam and the side frame, thereby increasing the cushioning effect.
