본 고안은 자동차용 충돌시 충격에너지를 흡수하여 운전자에게 치명적인 손상을 줄일 수 있도록 한 자동차용 조향핸들 컬럼의 구조에 관한 것이다.The present invention relates to a structure of a steering wheel column for a vehicle to absorb the impact energy in the collision of the vehicle to reduce the fatal damage to the driver.

일반적으로 자동차용 조향핸들은 자동차의 진행방향을 임의로 조정하기 위해 기어박스측과, 조향핸들간을 조향축에 의해 연결하고 그 외주연에는 내, 외파이프가 결합된 컬럼에 의해 보호되는 상태로 자동차의 차체에 고정토록 하는 것이다.In general, the steering wheel for automobile is connected to the gearbox side and the steering wheel by steering shaft to arbitrarily adjust the driving direction of the vehicle, and the outer circumference of the steering wheel is protected by a column in which inner and outer pipes are coupled. To be fixed to the body of the car.

그런데 종래의 컬럼(51)은 제5도 및 제6도에서와 같이 내, 외파이프(52)(53)를 삽입하여 결합하되, 자동차의 충돌시 마찰하중을 높일수 있도록 내파이프(52)의 90°선상에 길이방향으로 돌기부(54)를 엠보하여 돌기부(54)와 외파이프(53) 내면과 긴밀히 접촉된 상태로 삽입고정하였다.However, the conventional column 51 is combined with the inner pipes 52 and 53 by inserting the inner pipes 52 and 53 as in FIGS. 5 and 6, but the 90 of the inner pipes 52 may be increased to increase the frictional load during the collision of the vehicle. The projections 54 were embossed in the longitudinal direction on the line, and inserted and fixed in intimate contact with the inner surfaces of the projections 54 and the outer pipe 53.

그러나, 상기와 같은 컬럼(51)은 자동차의 주행중 충돌시에 외파이프(53)는 내파이프(52)에 길이방향으로 형성된 돌기부(54)를 누르면서 길이방향으로 미끄러져 압입되어 충격에너지의 흡수가 용이치 못하는 결점이 있었을 뿐만 아니라, 조향핸들 컬럼(51)을 이루는 내파이프(52)의 90°선상에 길이방향으로 돌기부(54)의 엠보시 치수관리가 어려워 하중관리가 어려웠던 한편, 돌기부(52)의 각 부위별 형상이 정확하지 않아 제품불량이 과다하게 발생되는 문제점이 야기되었다.However, as described above, the column 51 slides in the longitudinal direction while pressing the protrusion 54 formed in the longitudinal direction in the inner pipe 52 during the collision of the vehicle while driving the vehicle, thereby absorbing the impact energy. Not only was there a faulty defect, it was difficult to control the embossed dimensions of the projections 54 in the longitudinal direction on the 90 ° line of the inner pipe 52 constituting the steering wheel column 51, and the load management was difficult. The shape of each part of the) is not accurate, causing a problem of excessive product defects.

본 고안은 상기한 종래의 제문제점등을 해결하기 위하여 안출된 것으로서 본 고안의 그 목적으론, 조향핸들 컬럼의 내, 외파이프를 결합하되, 내, 파이프 또는 파이프 자체에 선택적으로, 돌기부를 내향 또는 외향 벤딩하여 조립을 간편용이하게 하고 자동차의 충돌시 돌기부의 마찰에 의해 충격에너지 흡수를 가일층 높이려는 것이 그 특징이다.The present invention has been made to solve the above-mentioned problems, the purpose of the present invention is to combine the inner and outer pipes of the steering wheel column, the inner, the pipe or the pipe itself, optionally, the projection inward or It is characterized by the fact that it is easy to assemble by bending outward and to further increase the absorption of impact energy by friction of the projections during the collision of the vehicle.

상기의 목적을 달성할 수 있는 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When the present invention to achieve the above object will be described in detail by the accompanying drawings as follows.

제1도 및 제3도에서와 같이 조향축외주연에 설치되는 컬럼(1)을 내, 외파이프(2)(3)로 상호조립 구성하되, 상기 외파이프(3)의 외주연 수개의 지점을 절단한후 내향절곡시켜 돌기부(4)를 형성하여, 내파이프(2)는 억지끼움 결합구성된 것이다.As shown in FIG. 1 and FIG. 3, the column 1 installed at the outer periphery of the steering shaft is assembled with the outer pipes 2 and 3, and several points of the outer periphery of the outer pipe 3 are formed. After cutting, inward bending is performed to form the projections 4, the inner pipe 2 is configured to be interference fit.

이때 내파이프(2)는 외파이프(3)의 외주연 수개의 점에 내향 절곡된 돌기부(4)와 충격에너지를 할수 있는 상태로 압입고정 되는 것이다.At this time, the inner pipe 2 is press-fitted and fixed in a state capable of impact energy with the protruding portion 4 bent inward at several points of the outer circumference of the outer pipe 3.

이와같이 구성된 본 고안의 컬럼(1)은 자동차의 주행중 충돌시 충격에너지가 가해지면 외파이프(3)의 외연에 내향절곡 형성된 돌기부(4)와 내파이프(2)의 외주연과 마찰을 일으키면서 그 마찰에 의해 충격을 흡수하게 되는 것이다.The column 1 of the present invention configured as described above causes friction with the outer periphery of the protrusion 4 and the inner pipe 2 formed inwardly bent on the outer edge of the outer pipe 3 when impact energy is applied during the driving of the vehicle. The shock is absorbed by friction.

제4도는 본 고안의 다른 실시예 결합단면도로서 컬럼(1)을 내, 외파이프(2)(3)로 조립구성함에 있어서, 내파이프(2)의 외주연 다수의 지점을 절단한 후 내향절곡시켜 돌기부(4')를 외향절곡 형성하여 외파이프(3)를 억지끼움 결합한 것이다.4 is a cross-sectional view of another embodiment of the present invention in which the column 1 is assembled into the outer pipe 2 and the inner pipe 2, and the inner periphery of the inner pipe 2 is cut and then inwardly bent. By forming the protrusions 4 'outwardly bent to force the outer pipe (3) is combined.

이와같이 구성된 본 고안의 다른 실시예에 있어서도 전자와 같이 자동차의 주행중 충돌시 충격에너지가 가해지면 내파이프(2) 외주연에 외향절곡형성된 다수의 돌기부(4')가 외파이프(3)의 내면과 마찰되면서 충격에너지를 흡수토록하게 되는 것이다.In another embodiment of the present invention configured as described above, when the impact energy is applied during the collision of the vehicle as in the former, a plurality of protrusions 4 ′ formed outwardly bent on the outer circumference of the inner pipe 2 are formed with the inner surface of the outer pipe 3. The friction is to absorb the impact energy.

이상 설명한 바와같이 컬럼을 구성하는 내, 외파이프의 외주연에 선택적으로 외향 또는 내향절곡된 돌기부를 형성한 후 자동차의 충돌시 충격에너지가 돌기부와 내, 외파이프의 내면 또는 외면과 마찰되면서 충격에너지를 흡수토록한 유용한 고안이다.As described above, after forming protrusions which are selectively outwardly or inwardly bent on the outer periphery of the inner and outer pipes constituting the column, the impact energy is rubbed with the protrusions and the inner and outer surfaces of the outer pipe during impact of the vehicle. It is a useful design to absorb.
