Description
본 고안은 자동차의 스티어링 휠 구동장치에 관한 것이며, 보다 상세히는 차량의 충돌시 운전석 또는 조수석 에어백의 전개와 동시에 스티어링 휠이 후진 되도록하는 스티어링 휠 구동장치에 관한 것이다.The present invention relates to a steering wheel driving apparatus of a vehicle, and more particularly to a steering wheel driving apparatus for allowing the steering wheel to move backwards with the deployment of the driver's seat or the passenger seat airbag during a collision of the vehicle.
종래의 충돌 안전 장치인 경우, 차량의 충돌이 발생되면 운전석 또는 조수석의 에어백이 전개되어 승객을 보호하게 된다. 그러나, 에어백의 미전개로 운전자가 스티어링 휠에 부딪혀 다치는 경우가 많고, 차체가 찌그러지는 충돌 사고시 운전자가 운전대에 끼여 효과적으로 탈출 또는 피신을 할 수 없는 경우가 발생된다.In the case of a conventional collision safety device, when a vehicle collision occurs, an airbag of a driver's seat or a passenger seat is deployed to protect a passenger. However, the driver is often injured by hitting the steering wheel due to the undeployment of the airbag, and the driver cannot be effectively escaped or escaped by being caught in the steering wheel during a collision accident in which the vehicle body is crushed.
따라서, 본 고안은 상술한 종래의 문제점을 극복하기 위한 것으로서, 본 고안의 목적은 차량의 충돌되면 스티어링 휠 및 그 샤프트가 후진되어 운전자의 얼굴 또는 가슴을 압박하지 않게 하며, 더욱이 심한 충돌시 운전대 사이에 운전자가 탈출하지 못하는 경우를 방지하는 스티어링 휠 구동장치를 제공하는데 있다.Therefore, the present invention is to overcome the above-mentioned conventional problems, the object of the present invention is that when the collision of the vehicle steering wheel and its shaft is reversed so as not to press the driver's face or chest, even more severe between the steering wheel during the collision The present invention provides a steering wheel driving device for preventing a driver from escaping.
상기 본 고안의 목적을 달성하기 위한 스티어링 휠 구동장치의 일예로서, 내주면에 브레이드가 구비되며 하부에 플랜지가 연장된 스티어링 휠 샤프트의 구동부와, 상기 구동부의 일부를 수용하고 있는 케이스와, 상기 케이스의 바닥면에서 수직하게 연장된 가이드부와, 가스실에 충진된 가스를 폭발시키는 인플레이터와, 상기 플랜지 하부에 위치한 스프링으로 구성되어, 충돌이 일어나면 상기 인플레이터가 점화된다.As an example of a steering wheel drive device for achieving the object of the present invention, a blade is provided on the inner peripheral surface and the drive portion of the steering wheel shaft with a flange extending in the lower portion, a case accommodating a portion of the drive portion, It consists of a guide portion extending vertically from the bottom surface, an inflator for exploding the gas filled in the gas chamber, and a spring located below the flange, so that the inflator is ignited when a collision occurs.
이러한 구성에 의해, 운전대가 충돌시 후진되어 운전자를 보호하게 된다.With this arrangement, the steering wheel is reversed in the event of a collision to protect the driver.

이하, 본 고안의 실시예를 도 1 및 도 2를 참조하여 상세히 설명하기로 한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.
도 1을 참조하면, 본 고안에 따른 스티어링 휠 구동장치는 내주면에 브레이드(15)가 구비되며 하부에 플랜지(23)가 연장된 스티어링 휠 샤프트의 구동부(11)와, 상기 구동부의 일부를 수용하고 있는 케이스(27)와, 상기 케이스(27)의 바닥면에서 수직하게 연장된 가이드부(32)와, 가스실(17)에 충진된 가스를 폭발시키는 인플레이터(19)와, 상기 플랜지(23) 하부에 위치한 스프링(21)으로 구성된다.Referring to Figure 1, the steering wheel driving apparatus according to the present invention is provided with a braid 15 on the inner circumferential surface and receives a drive portion 11 and a portion of the drive portion of the steering wheel shaft extending flange 23 at the bottom A case 27, a guide portion 32 extending vertically from the bottom surface of the case 27, an inflator 19 for exploding gas filled in the gas chamber 17, and a lower portion of the flange 23. Consists of a spring 21 located in.
상기 구동부(11) 내에는 피구동부(13)가 장착된다.The driven part 13 is mounted in the driving part 11.
상기와 같은 구성에 의해 본 고안의 스티어링 휠 구동장치는 다음과 같이 작동한다.By the above configuration, the steering wheel driving device of the present invention operates as follows.
충돌이 발생되면, 이를 충돌 센서(1)에서 감지하게 된다. 그러면, ECU(2)는 운전석 및 조수석의 에어백을 구동시키는 인플레이터(3)를 작동시킨다. 또한, ECU(2)는 스티어링 휠 구동용 인플레이터(19)를 작동시킨다.When a collision occurs, it is detected by the collision sensor 1. The ECU 2 then operates the inflator 3 which drives the airbags of the driver's seat and the passenger seat. In addition, the ECU 2 operates the inflator 19 for driving a steering wheel.
이 인플레이터(19)가 구동되면, 가스실(17)의 가스가 팽창하여, 그 팽창력으로 구동부(11)의 플랜지(23)를 하방으로 밀게 된다. 이때, 구동부(11)는 블레이드(15)로 인하여 회전되지는 않게 된다. 이렇게 구동부(11)가 후진함으로서 구동부의 상단에 장착된 스티어링 휠도 후진되는 것이다.When the inflator 19 is driven, the gas in the gas chamber 17 expands, and the flange 23 of the drive unit 11 is pushed downward by the expansion force. At this time, the driving unit 11 is not rotated due to the blade (15). As the driving unit 11 moves backward, the steering wheel mounted on the upper end of the driving unit also moves backward.
상술한 바와 같이 본 고안에 따른 스티어링 휠 구동장치는 차량이 충돌되면 스티어링 휠 및 그 샤프트가 후진되어 운전자의 얼굴 또는 가슴을 압박하지 않게 하며, 더욱이 심한 충돌시 운전대 사이에 운전자가 탈출하지 못하는 경우를 방지하게 된다.As described above, when the vehicle collides, the steering wheel driving apparatus according to the present invention prevents the steering wheel and its shaft from being retracted so as not to press the driver's face or chest, and furthermore, the driver may not escape between the steering wheel during a severe collision. Will be prevented.
이상에서 설명한 것은 본 고안에 따른 스티어링 휠 구동장치를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 고안은 상기한 실시예에 한정되지 않고, 이하의 실용신안등록청구의 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변경 실시가 가능할 것이다.What has been described above is just one embodiment for implementing a steering wheel driving apparatus according to the present invention, the present invention is not limited to the above embodiment, the present invention of claim in the following utility model registration claims Various modifications can be made by those skilled in the art without departing from the gist of the present invention.
