조향장치는 일반적으로 운전자로부터 회전력을 전달받는 조향휠, 조향휠로부터 회전력을 전달받는 조향축 및 조향축이 삽입된 상부 컬럼과 하부 컬럼을 포함하는데, 이러한 상부 컬럼과 하부 컬럼은 각각 상부 브라켓 및 하부 브라켓에 의해 차체에 고정되게 된다. 이러한 조향장치에는 자동차의 전방 충돌시 충돌 관성으로 인해 운전자가 조향휠에 부딪쳤을 때 그 충격력을 흡수 및 완화하여 충격량을 감소시켜서 운전자의 상해를 최소화하도록 하기 위한 충격 에너지 흡수구조가 다양하게 개발되어 설치되고 있다.Steering devices generally include a steering wheel that receives rotational force from the driver, a steering shaft that receives rotational force from the steering wheel, and an upper column and a lower column into which the steering shaft is inserted. The upper column and the lower column are respectively an upper bracket and a lower column. It is fixed to the vehicle body by the bracket. These steering devices are developed and installed in a variety of shock energy absorbing structure to minimize the driver's injury by reducing the amount of impact by absorbing and mitigating the impact force when the driver hits the steering wheel due to the collision inertia during the front collision of the car have.

도 1은 종래의 조향 컬럼의 사시도이다. 도 1에 도시된 바와 같이, 조향 컬럼(Steering Column: 100)은 외측 튜브(120), 내측 튜브(110), 하부 마운팅 브라켓(140) 및 상부 마운팅 브라켓(130)을 포함한다. 1 is a perspective view of a conventional steering column. As shown in FIG. 1, the steering column 100 includes an outer tube 120, an inner tube 110, a lower mounting bracket 140, and an upper mounting bracket 130.

외측 튜브(120)는 조향휠 측에 형성되어 있으며, 내부에는 외측 튜브(120) 보다 외경이 작아 충격시 외측 튜브(120) 내부로 슬라이딩하는 내측 튜브(110)가 삽입되며 내측 튜브는 하부 마운팅 브라켓(140)에 고정되어 차체에 결합된다. 또한, 외측 튜브(120) 및 내측 튜브(110)는 중공 튜브로서 충격시 그 내부에 수축 가능한 조향축을 포함하며 조향축이 원활하게 회전할 수 있는 공간이 형성되어 있다.The outer tube 120 is formed on the steering wheel side, the outer diameter is smaller than the outer tube 120, the inner tube 110 is inserted into the inner tube 110 sliding in the outer tube 120 during impact, the inner tube is a lower mounting bracket It is fixed to 140 is coupled to the vehicle body. In addition, the outer tube 120 and the inner tube 110 is a hollow tube includes a steering shaft that can be contracted therein when impacted, and a space in which the steering shaft can rotate smoothly is formed.

도 2는 도 1에 도시된 외측 튜브가 내측 튜브로 이동되는 모습을 나타낸 측면도이다. 자동차의 충돌 사고시 운전자가 조향휠(미도시)에 충격을 가했을 때 외측 튜브(120)가 내측 튜브(110) 방향으로 이동하면서 충격을 흡수하고 외측 튜브(120)가 최대한 이동되었을 때의 모습을 도시한 도면이다.Figure 2 is a side view showing a state in which the outer tube shown in Figure 1 is moved to the inner tube. When the driver impacts the steering wheel (not shown) during the collision of the vehicle, the outer tube 120 moves toward the inner tube 110 to absorb the shock and the outer tube 120 is moved as much as possible. One drawing.

외측 튜브의 외주면 일측에는 자동차의 키를 삽입하기 위한 키-셋부(200, Key-Set부)가 형성되어 있다. 키-셋부(200)는 자동차의 키를 삽입한 후 키를 회전하여 자동차의 전원을 인가하고 스타트 모터(미도시)를 구동하여 엔진(미도시)의 시동을 거는 역할 및 자동차의 도난을 방지하기 위하여 키가 키-셋부(200)에 삽입되지 않은 상태에서 조향을 할 경우 조향휠이 일정량 회전하다가 더 이상 조향되지 않고 고정되는 키-락(Key-Lock) 기능을 구비한다.On one side of the outer circumferential surface of the outer tube, a key-set part 200 (Key-Set part) for inserting a key of a vehicle is formed. The key-set unit 200 inserts a key of the vehicle and rotates the key to apply power to the vehicle and drive a start motor (not shown) to start the engine (not shown) and to prevent theft of the vehicle. In order to steer in a state where the key is not inserted into the key-set part 200, the steering wheel is rotated by a certain amount and has a key-lock function that is fixed without being steered.

현재 조향 컬럼(100)은 점차 짧게 개발되고 있는 추세이며 이에 따라 조향 컬럼(100)의 충격 흡수량 또한 확보하기가 어려워졌으며, 자동차의 충돌 사고시 외측 튜브(120)가 내측 튜브(110) 방향으로 이동하면서 충격을 흡수하다가 내측 튜브(110)의 일단부가 키-셋부(200)와 부딪쳐서 이동이 중지되어 더 이상 충격을 흡수하지 못하고 운전자에게 충격을 가하는 문제점이 있었다.At present, the steering column 100 is gradually developed and thus it is difficult to secure the shock absorbing amount of the steering column 100. As the outer tube 120 moves in the direction of the inner tube 110 during a collision of the vehicle, While absorbing the shock, one end of the inner tube 110 hits the key-set part 200 and the movement is stopped, so that there is a problem in that the shock is not absorbed any more and the driver is shocked.

이러한 문제점을 해결하기 위해 본 발명은, 조향장치에 구비된 내측 튜브의 단부에 키-셋 홈을 형성함으로써 자동차의 충돌 사고시 운전자의 신체가 조향휠에 충격을 가했을 때 외측 튜브가 내측 튜브로 이동되는 거리를 증가시켜 충격 흡수량을 확보하는 키-셋 홈이 형성된 내측 튜브를 구비한 조향장치를 제공하는 데 그 목적이 있다.In order to solve this problem, the present invention, by forming a key-set groove in the end of the inner tube provided in the steering apparatus, the outer tube is moved to the inner tube when the driver's body impacts the steering wheel during the collision of the vehicle It is an object of the present invention to provide a steering apparatus having an inner tube with a key-set groove formed to increase the distance to secure the shock absorbing amount.

이러한 목적을 달성하기 위해 본 발명은, 자동차의 앞바퀴가 선회하는 회전 중심을 임의로 변경하여 상기 자동차를 선회시키며, 운전자를 보호하기 위한 충격 흡수 장치 중 조향 컬럼에 외측 튜브 및 내측 튜브를 구비한 조향장치에 있어서, 자동차의 충돌 사고 발생시 외측 튜브가 내측 튜브로 최대로 이동되었을 때 외측 튜브에 구비된 키-셋부와 접하는 내측 튜브를 일부 절개하여 키-셋 홈을 내측 튜브에다 형성한 것을 특징으로 한다.In order to achieve the above object, the present invention provides a steering apparatus having an outer tube and an inner tube in a steering column of a shock absorbing device for turning the vehicle by arbitrarily changing the rotational center of the vehicle's front wheel. In the case of the collision of the vehicle, when the outer tube is moved to the inner tube to the maximum, the inner tube in contact with the key-set portion provided in the outer tube is partially cut and characterized in that the key-set groove is formed in the inner tube.

조향장치에 구비된 조향 컬럼(100)은 일반적으로 내측 튜브(110)와 외측 튜브(120)를 포함하여 구성된다. 원가 절감, 자동차의 경량화 및 조향 전달력 증대 등을 목적으로 조향 컬럼(100)의 전체 길이는 짧도록 하고, 외측 튜브(120)가 내측 튜브(110)로 이동되는 거리는 증가시켜 자동차의 충돌 사고시 충격을 흡수하는 거리 및 양을 증가하도록 하는 것이 최근의 추세이다.The steering column 100 provided in the steering apparatus generally includes an inner tube 110 and an outer tube 120. The overall length of the steering column 100 is shortened for the purpose of cost reduction, weight reduction of the vehicle, and increased steering transmission force, and the distance in which the outer tube 120 is moved to the inner tube 110 is increased to impact the collision of the car. It is a recent trend to increase the distance and the amount of absorption.

외측 튜브(120)가 내측 튜브(110)로 완전히 이동되었을 때 외측 튜브(120)에 구비된 키-셋부(200)에 내측 튜브(110)의 일측 단부가 접하여 충격 흡수 진행을 방해하는 것을 방지하며 외측 튜브(120)가 내측 튜브(110)로 이동되는 거리를 증가시키기 위해서, 내측 튜브(110)가 외측 튜브(120)에 구비된 키-셋부(200)에 접하는 부위를 일부 절개하여 키-셋 홈(300, Key-Set Groove)을 형성한다.When the outer tube 120 is completely moved to the inner tube 110, one end of the inner tube 110 is in contact with the key-set portion 200 provided in the outer tube 120 to prevent the shock absorbing process from interfering. In order to increase the distance that the outer tube 120 is moved to the inner tube 110, a portion of the inner tube 110 in contact with the key-set portion 200 provided in the outer tube 120 is incised to the key-set A groove 300 is formed to form a key set groove.

내측 튜브(110)를 일부 절개하여 키-셋 홈(300)을 형성함으로써 발생하는 외측 튜브(120)와 내측 튜브(110) 간의 지지력을 보강하기 위해 내측 튜브(110)가 삽입되는 외측 튜브(120)의 단부 외주면에 복수개의 지지구(400)를 형성한다.The outer tube 120 into which the inner tube 110 is inserted to reinforce the bearing force between the outer tube 120 and the inner tube 110 generated by partially cutting the inner tube 110 to form the key-set groove 300. A plurality of supports 400 is formed on the outer peripheral surface of the end.

지지구(400)는 동일 원주상에 3 ~ 4개 형성하며 1 ~ 3열로 형성하는 것이 바람직하다. 지지구(400)의 형성 방법은 외측 튜브(120)의 외주면을 사각형 모양으로 일부 절개하되 키-셋부(200)와 가까운 쪽은 고정되어 있도록 하고 나머지 3면을 절개한 후 고정되어 있는 부위를 외측 튜브(120)의 내주면 방향으로 절곡하되 지지구(400)의 내면과 외측 튜브(120)의 내주면이 마주보도록 절곡한다. The support 400 is preferably formed in three to four rows on the same circumference. The method of forming the supporter 400 is to make a partial incision in the outer peripheral surface of the outer tube 120 in a rectangular shape so that the side close to the key-set part 200 is fixed, and after cutting the remaining three surfaces outside the outer portion The inner circumferential surface of the tube 120 is bent, but the inner surface of the supporter 400 and the inner circumferential surface of the outer tube 120 are bent to face each other.

지지구(400)를 형성한 후 내측 튜브(110)를 외측 튜브(120)에 삽입하게 되면 지지구(400)가 내측 튜브(110)의 외주면을 가압하게 되어 내측 튜브(110)에 키-셋 홈(300)을 구비하더라도 적정한 지지 강성을 유지하게 된다.When the inner tube 110 is inserted into the outer tube 120 after the supporter 400 is formed, the supporter 400 presses the outer circumferential surface of the inner tube 110 to key-set the inner tube 110. Even if the groove 300 is provided, the proper support rigidity is maintained.
