Abstract

PURPOSE: Structure of a collision-preventing steering column is provided to improve the safety and commercial value of a vehicle by preventing the injury on a driver in a collision of a vehicle. CONSTITUTION: An upper tube(101) having a piston(103) is installed on the inner upper portion of a hollow core housing(104) having a ventilation hole(106). A lower tube(107) having a descending space(107a) is installed on the inner lower portion of the housing. The lower end of the upper tube is connected with the lower tube via a connecting pin(105). An inflator(102) is installed between the inner upper end of the housing and the upper end of the piston. The inflator is connected to a control unit(108) and a shock sensor(109). Since the upper tube and a steering wheel descend upon a collision of a vehicle, the injury on a driver inclined toward a steering wheel is prevented.

Description

충돌방지형 스티어링 칼럼 구조{STEERING COLUMN FOR PREVENTING VEHICLE COLLISION}Collision-proof steering column structure {STEERING COLUMN FOR PREVENTING VEHICLE COLLISION}

본 발명은 자동차 정면 충돌시에 스티어링 휠에 의해 운전자가 부상을 당하는 것을 방지할 수 있도록 하는 충돌방지형 스티어링 칼럼 구조에 관한 것으로, 더 자세하게는 자동차 정면 충돌시에 스티어링 휠이 설치된 상부튜브가 하강할 수 있도록 한 것에 관한 것이다.The present invention relates to an anti-collision steering column structure that can prevent a driver from being injured by a steering wheel during a frontal collision of a vehicle, and more particularly, an upper tube installed with a steering wheel during a frontal collision of a vehicle may descend. It's about making things happen.

일반적으로 자동차의 정면 충돌이 방생하게 되면 운전자의 몸이 앞쪽으로 쏠리면서 스티어링 휠에 부딪히게 되어 운전자가 부상을 입게 되는 일이 많게 되는 바, 종래에 있어서 이와 같이 스티어링 휠에 부딪히는 운전자의 부상을 저감할 수 있도록 하는 충격방지형 스티어링 칼럼구조는 도 1과 같이 차량의 정면 충돌시 엔진힘으로 스티어링 휠이 고정되는 상부튜브(12)를 끌어내려 스티어링 칼럼(10)이 자동으로 붕괴되도록 슬롯홈(10)을 중심으로 하여 유니버셜조인트 및 상부튜브(13)를 4절링크(14)에 연결시킨 것과, 도 2와 같이 스티어링 칼럼(22)에 요철부(23)를 형성하여 충돌 발생시 변형되면서 충돌에너지를 흡수하도록 하는 것 등이 제안되었다.In general, when the frontal collision of the car occurs, the driver's body is leaned forward and hits the steering wheel, which causes the driver to be injured. Thus, the injury of the driver who hits the steering wheel in the related art is reduced. The shockproof steering column structure which allows the slot groove 10 to automatically collapse the steering column 10 by pulling down the upper tube 12 to which the steering wheel is fixed by the engine power when the front collision of the vehicle as shown in FIG. The universal joint and the upper tube 13 are connected to the four-section link 14 around the center, and as shown in FIG. 2, the uneven portion 23 is formed in the steering column 22 to deform when collision occurs. Absorption has been proposed.

그러나 상기 종래 구조들은 그 구조가 복잡하여 제작이 어렵고 비용이 많이 들 뿐 아니라 일단 스티어링 휠에 운전자의 충돌이 일어난 후에야 비로소 스티어링 칼럼의 변형이 이루어지기 때문에 어느 정도의 부상을 감수할 수밖에 없는 문제가 있었다.However, the conventional structures have a problem in that the structure is complicated and difficult to manufacture and expensive, and the steering column is deformed only after the driver's collision occurs in the steering wheel. .

본 발명은 상기와 같은 종래 구조의 제결함을 감안하여 안출한 것이며, 그목적이 자동차 정면 충돌시 운전자가 스티어링 휠에 부딪치게 되어 부상을 입게 되는 것을 효과적으로 방지할 수 있도록 하는 충돌방지형 스티어링 칼럼 구조를 제공하는 데에 있는 것이다.The present invention has been made in view of the above-described deficiencies of the conventional structure, the purpose of the collision-proof steering column structure that can effectively prevent the driver from colliding with the steering wheel when the front of the car hit the steering wheel injuries. It is to provide.

본 발명은 상기의 목적을 달성하기 위하여 중공상의 하우징의 내상부에 피스톤을 갖는 상부튜브를 설치하고, 하우징의 내하부에 하강공간부가 내상단부에 마련된 하부튜브를 설치하며, 하부튜브의 하강공간부 내상부에 삽입되는 상부튜브의 하단부를 연결핀을 통해 접속하는 한편, 하우징 내상단과 피스톤 상단 사이에 인플레이터를 설치하고, 이 인플레이터를 제어부 및 충격센서에 접속하는 것을 특징으로 하며, 이하 그 구체적인 기술내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.The present invention is to provide an upper tube having a piston in the inner upper portion of the hollow housing in order to achieve the above object, to install a lower tube provided with a lower space portion in the inner upper end of the lower housing, the lower space portion of the lower tube While connecting the lower end of the upper tube inserted into the upper portion through the connecting pin, an inflator is installed between the upper end of the housing and the upper end of the piston, and the inflator is connected to the control unit and the impact sensor. The content is described in more detail based on the attached drawings as follows.

즉, 도 3에는 본 발명의 한 실시예가 도시되어 있는 바, 본 발명은 하단 일측에 배기홀(106)이 형성되는 중공상의 하우징(104)의 내상부에 피스톤(103)이 외주에 마련된 상부튜브(101)를 설치하고, 하우징(104)의 내하부에 하강공간부(107a)가 내상단부에 마련된 하부튜브(107)를 설치하며, 하부튜브(107)의 하강공간부(107a) 내상부에 삽입되는 상부튜브(101)의 하단부를 연결핀(105)을 통해 하부튜브(107)와 접속하는 한편, 하우징(104) 내상단과 피스톤(103) 상단 사이에 인플레이터(102)를 설치하고, 이 인플레이터(102)를 제어부(108) 및 자동차 전면범퍼(미도시) 등에 설치되는 충격센서(109)에 접속하여서 되는 것이다.That is, one embodiment of the present invention is shown in Figure 3, the present invention is the upper tube is provided on the outer periphery of the piston 103 in the inner upper portion of the hollow housing 104, the exhaust hole 106 is formed on one side of the lower end 101 is installed, and a lower tube 107 having a lower space 107a is provided in the upper and lower ends of the housing 104, and an inner upper portion of the lower space 107a of the lower tube 107. While connecting the lower end of the upper tube 101 to be inserted into the lower tube 107 through the connecting pin 105, the inflator 102 is installed between the upper end of the housing 104 and the upper end of the piston 103, The inflator 102 is connected to the control unit 108 and the impact sensor 109 provided on the vehicle front bumper (not shown).

상기와 같이 구성된 본 발명에 있어서는 자동차의 정면 충돌이 발생하게 되면 즉각적으로 자동차 전면범퍼 등에 설치되는 충격센서(109)가 작동하게 되어 제어부(108)에서 인플레이터(102)로 폭발신호를 보내게 되게 되므로 인플레이터(102)가 폭발하게 되는 것으로, 인플레이터(102)가 폭발하게 되면 그 폭발력으로 피스톤(103) 및 상부튜브(101)가 하강하게 되고, 그 하강력에 의해 연결핀(105)이 파손되어 상부튜브(101)의 하단부가 하부튜브(107)의 하강공간부(107a) 깊숙이 하강하게 되므로 상부튜브(101)에 설치되는 스티어링 휠(미도시)이 하강하게 되며, 그에 따라 관성력에 의해 운전자의 몸이 스티어링 휠쪽으로 쏠리게 되더라도 하강한 스티어링 휠에는 운전자의 몸이 닿지 않게 되므로 스티어링 휠에 의한 운전자의 부상을 효과적으로 방지할 수 있게 되는 것이다.In the present invention configured as described above, when a frontal collision of the vehicle occurs, the impact sensor 109 installed on the front bumper of the vehicle is immediately activated, so that the control unit 108 sends an explosion signal to the inflator 102. The inflator 102 is to be exploded, and when the inflator 102 is exploded, the piston 103 and the upper tube 101 is lowered by the explosive force, and the connecting pin 105 is broken by the lowering force, thereby Since the lower end of the tube 101 is lowered deeply in the lower space 107a of the lower tube 107, the steering wheel (not shown) installed in the upper tube 101 is lowered, and accordingly the body of the driver by the inertia force Even if the steering wheel is pulled toward the steering wheel, the lowered steering wheel does not touch the driver's body, thereby effectively preventing the driver's injury from the steering wheel. to be.

이상에서 설명한 바와 같이 본 발명은 자동차의 전면범퍼 등에 설치한 충격센서(109)를 통해 충돌을 감지하는 경우 제어부(108)에서 하우징(104)에 설치한 인플레이터(102)의 폭발시켜 스티어링 휠이 설치되는 상부튜브(101)를 하강시킬 수 있도록 한 것으로, 본 발명에 의하면 자동차의 충돌과 거의 동시에 상부튜브(101) 및 스티어링 휠이 하강하게 되므로 충돌에 의해 스티어링 휠쪽으로 쏠리게 되는 운전자의 부상을 더욱 효과적으로 방지할 수 있게 되어 자동차의 안전성과 상품성을 일층 향상시킬 수 있게 되는 등의 효과를 얻을 수 있게 된다.As described above, in the present invention, when the collision is detected through the impact sensor 109 installed on the front bumper of the vehicle, the steering wheel is installed by exploding the inflator 102 installed in the housing 104 by the controller 108. It is to be able to lower the upper tube 101, according to the present invention, the upper tube 101 and the steering wheel is lowered almost at the same time as the collision of the vehicle, so that the injury of the driver to be directed toward the steering wheel by the collision more effectively It is possible to prevent the effects, such as to further improve the safety and merchandise of the car.
