Description
본 발명은 충격흡수기능을 갖는 차량의 조향휠에 관한 것으로, 보다 상세하게는 차량의 충격에 의해 이동되는 승객으로부터 가해지는 충격을 흡수·완충할 수 있도록 된 충격흡수기능을 갖는 차량의 조향휠에 관한 것이다.The present invention relates to a steering wheel of a vehicle having a shock absorbing function, and more particularly, to a steering wheel of a vehicle having a shock absorbing function capable of absorbing and buffering a shock applied from a passenger moved by the impact of the vehicle. It is about.
일반적으로 차량의 운전석에 구비된 조향휠은 자동차의 주행시 운전자가 진행방향을 조작하는 데에 사용되지만, 만약 주행 중에 외부에서 충격이 가해지거나 급정거하는 경우, 차량의 운동에너지가 운전자에게 그대로 전달되므로 운전자가 안전벨트를 착용하였더라도 신체의 머리부위나 가슴부위가 조향휠부위에 부딪치게 되고, 이에 따라 통상 비탄성체의 굳은 재질로 이루어진 조향휠의 특성상 운전자에게 치명적인 부상을 입히는 문제점이 있다.In general, the steering wheel provided in the driver's seat of the vehicle is used by the driver to control the driving direction while driving the vehicle. However, if the vehicle is impacted or suddenly stopped while driving, the driver's kinetic energy is transmitted to the driver as it is. Even if the seat belt is worn, the head or chest of the body hits the steering wheel, and thus there is a problem of causing a fatal injury to the driver due to the characteristics of the steering wheel made of a hard material of inelastic material.
이러한 문제점을 보안하고자 충돌 사고시에 탑승자를 안전하게 보호하기 위해 조향휠에 에어백 시스템을 장착하지만, 이와 같은 에어백은 그 설치 비용이 고가이므로 장착하지 않은 차량이 많음은 물론, 차속이 약 50~60km 이상의 속도에서 주행 시 충돌사고에 의해서만 펼쳐지는 문제점이 고 또한 급정거로 인해 위급한 상황에서 펼쳐지지는 않아 운전자의 신체가 조향휠부위로 충돌하는 현상으로부터 운전자의 부상을 방지하기에는 한계가 있는 문제가 있게 된다.In order to secure this problem, the airbag system is mounted on the steering wheel to protect the occupants in the event of a crash. However, such airbags are expensive to install, so many vehicles are not installed and the speed of the vehicle is about 50 to 60 km or more. It is a problem that is unfolded only by a collision accident when driving in a road, and is not unfolded in an emergency situation due to a sudden stop, so there is a problem that a driver's body is prevented from crashing to a steering wheel part and thus there is a limit problem.
또한, 이와 같이 에어백을 장착한 경우 펼쳐지면서 조향휠 쪼긍로 이동되는 운전자의 얼굴 부위를 가리면서 급격하게 펼쳐지므로 에어백의 충격으로 인해 오히려 호흡곤란을 겪는 위급한 문제점이 있는 단점이 있게 된다.In addition, when the airbag is mounted as described above, the airbag is unfolded rapidly while covering the driver's face, which is moved by the steering wheel, and thus has an emergency problem of experiencing difficulty in breathing due to the impact of the airbag.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 조향휠로 운전자가 부딪히더라도 충격이 가해지는 조향휠 부위가 변형되면서 충격을 흡수·완충해 운전자의 부상을 방지함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and the object of the present invention is to prevent the injury of the driver by absorbing and buffering the shock while the steering wheel part is deformed even when the driver hits the steering wheel.

도 1은 본 발명에 따른 충격흡수기능을 갖는 차량의 조향휠의 구성도를 도시한 것인바, 본 발명은 조향휠이 스포크(2)를 매개로 원형을 유지하는 상부림(1)의 하부부위에서 스포크(2)의 분기된 결합보스(2a)를 매개로 서로 분리되어 결합된 하부림(1')으로 이루어지되, 상기 하부림(2)의 내부에는 가해지는 충격에 의해 발생되는 콘트롤러(9)의 제어신호를 통해 변형되어 운전자의 손상을 방지하는 변형수단(3)이 구비되어진다.1 is a block diagram of a steering wheel of a vehicle having a shock absorbing function according to the present invention, the present invention is a lower portion of the upper rim (1) in which the steering wheel maintains a circle through the spoke (2) Consists of the lower rim (1 ') is separated from each other through the branched coupling boss (2a) of the spoke (2) in the controller, which is generated by the impact applied to the interior of the lower rim (2) Deformation means (3) is provided through the control signal of the) to prevent damage to the driver.
여기서, 상기 변형수단(3)은 도 2에 도시된 바와 같이 스포크(2)의 분기된 결합보스(2a)와 분리된 하부림(1')을 서로 연결하는 변형튜브(4)에 의해 서로 연결되어지는데, 이 변형튜브(4)내에는 도 3에 도시된 바와 같이 하부림(1')의 내부에 수용된 압력 센서(10)의 신호에 의해 발화·폭발되도록 배터리와 전원회로를 연결하는 콘트롤러(9)에 의해 작동되는 인플레이터(5)와, 이 인플레이터(5)의 폭발에 따른 팽창에 의해 스포크(2)쪽으로 이동되는 이동플레이트(6), 이 이동플레이트(6)에 의해 스포크(2)의 결합보스(2a)를 감싸 이동되면서 그 길이가 수축되는 이동부재(8) 및 이 이동부재(8)를 지지하면서 충격에 의해 이동되는 하부림(1')과 함께 이동되는 가이드로드(7)로 이루어진다.Here, the deforming means 3 are connected to each other by a deformable tube 4 connecting the branched coupling boss 2a of the spoke 2 and the separated lower rim 1 'as shown in FIG. In the deformable tube 4, as shown in FIG. 3, a controller for connecting the battery and the power circuit so as to ignite and explode by the signal of the pressure sensor 10 accommodated inside the lower rim 1 '( An inflator 5 actuated by 9), a movable plate 6 which is moved towards the spoke 2 by expansion due to the explosion of the inflator 5, and the movable plate 6 of the spoke 2 To move around the engaging boss (2a) and the guide member (7) moved together with the lower member (1 ') that is moved by impact while supporting the movable member (8) and its length is contracted. Is done.
한편, 상기 하부림(1')에 내장된 압력 센서(10)는 충격 감지 성능을 높이도록 하부림(1')의 전체 구간을 따라 구비되어짐은 물론이다.On the other hand, the pressure sensor 10 embedded in the lower rim (1 ') is of course provided along the entire section of the lower rim (1') to increase the impact detection performance.
이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 주행 중인 차량의 충돌이나 또는 급정거에 따라 운전자의 신체가 관성력에 의해 조향휠로 이동되면서 운전자의 가슴부위로 조향휠의 하부부위를 가격하게 되면, 이 조향휠의 하부부위를 이루는 하부림(1')에 내장된 압력 센서(10)가 가해진 충격에 따라 콘트롤러(9)로 신호를 발생하고, 이와 같이 센서(10)의 신호를 받은 콘트롤러(9)가 내장된 프로그램(Program)에 따라 배터리의 전원을 통전시키도록 변형수단(3)의 인플레이터(5)와 전원회로를 이루게 된다.According to the present invention, when the driver's body moves to the steering wheel by inertial force and strikes the lower part of the steering wheel by the driver's chest, the lower rim of the steering wheel is formed. A signal is generated by the controller 9 according to the impact applied by the pressure sensor 10 embedded in the 1 ', and the controller 9 which receives the signal of the sensor 10 is in accordance with a built-in program. A power circuit is formed with the inflator 5 of the deforming means 3 so as to energize the battery.
이어, 상기 인플레이터(5)에 전원이 공급되면 순간적으로 폭발하면서 팽창해도 4에 도시된 바와 같이, 이동플레이트(6)를 스포크(2)의 결합보스(2a)쪽으로 이동시키게 되는데 즉, 상기 이동플레이트(6)가 인플레이터(5)의 팽창에 의해 이동부재(8)를 가압하면서 스포크(2)의 결합보스(2a)를 따라 수축되고 이때, 하부림(1')과 스포크(2)사이를 이어주는 변형튜브(4)는 상기 이동부재(8)의 수축을 원활히 하도록 그 길이 방향으로 찌그러지는 변형부(4a)를 형성하게 된다.Subsequently, when power is supplied to the inflator 5, even if it explodes instantaneously and expands, the moving plate 6 is moved toward the coupling boss 2a of the spoke 2, that is, the moving plate. 6 is contracted along the engaging boss 2a of the spoke 2 while pressing the movable member 8 by the expansion of the inflator 5, whereby the lower rim 1 'and the spoke 2 are connected. The deformation tube 4 forms a deformation portion 4a that is distorted in the longitudinal direction so as to facilitate the contraction of the movable member 8.
이와 같이, 상기 하부림(1')과 스포크(2)사이에서 일정 간격을 유지하고 있던 이동부재(8)가 운전자에 의해 가해진 충격에 의해 폭발된 인플레이터(5)를 통해 수축되면 도 5에 도시된 바와 같이, 상부림(1)과 동일 선상을 이루는 하부림(1')이 초기위치에서 변형위치로 이동되면서 운전자에 의해 가해진 충격력(F)을 분리되는 변형간격을 통해 흡수·완충해 신체 부상을 완화시킬 수 있게 된다.As such, when the movable member 8, which has been maintained at a constant distance between the lower rim 1 ′ and the spokes 2, is contracted through the inflator 5 exploded by the impact applied by the driver, it is shown in FIG. 5. As shown, the lower rim 1 ', which is in the same line as the upper rim 1, is moved from the initial position to the deformation position, absorbing and buffering the shock force F applied by the driver through the deformation interval separating the body injury. This can be alleviated.
이상 설명한 바와 같이 본 발명에 의하면, 조향휠이 서로 분리되는 상·하부림으로 형성하면서 운전자로부터 충격을 받는 하부림의 내부에는 가해지는 충격을 감지하는 센서의 신호에 따라 인플레이터를 폭발·팽창시켜 하부림을 충격 방향으로 이동시켜, 차량의 충돌이나 급정거에 의해 조향휠로 운전자가 부딪히더라도 충격을 받은 조향휠 부위가 변형되면서 충격을 흡수·완충해 운전자의 부상을 방지할 수 있는 효과가 있게 된다.As described above, according to the present invention, the steering wheel is formed with the upper and lower rims separated from each other, and the inflator is exploded and expanded in accordance with the signal of the sensor that senses the impact applied to the inside of the lower rim which is impacted by the driver. By moving the bulim in the impact direction, even if the driver hits the steering wheel due to a collision or sudden stop of the vehicle, the affected steering wheel part is deformed and absorbs and buffers the shock, thereby preventing the driver's injury. .
