Description

밴드플레이이트 타입 조향컬럼 충격흡수장치{Band plate typed steer column collapse absorbing device} Band plate type steer column collapse absorbing device

본 발명은 조향컬럼 충격흡수장치에 관한 것으로, 특히 부품수량을 줄이고 용이한 조립성을 갖는 밴드플레이이트 타입 조향컬럼 충격흡수장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering column shock absorbing device, and more particularly, to a band plate type steering column shock absorbing device having a reduced number of parts and easy assembly.

일반적으로 차량의 조향장치는 운전자의 정면으로 위치되므로, 충돌시 조향컬럼의 변형으로 인해 운전자 부상을 초래할 수 있는 위험성을 갖는다.In general, since the steering device of the vehicle is located in front of the driver, there is a risk that the driver may be injured due to deformation of the steering column during a collision.

차량 충돌시 조향컬럼의 충격하중(Collapse Load 또는 Break Away Load)에 대한 승객가슴 변형량의 관계는 각국 법규와 상품성 관련시험의 중요한 상해평가인자이다.The relationship of the passenger's chest deformation to the impact load (Collapse Load or Break Away Load) of the steering column in the event of a vehicle crash is an important injury evaluation factor in the national regulations and the commerciality test.

이를 만족하고 운전자 부상을 방지하기 위한 대표적인 방식으로 조향휠에 내장된 에어백이 있지만, 에어백의 작동 불량이나 또는 에어백 미 장착을 고려해 또 다른 방식으로 운전자의 부상을 방지한다.There is an airbag built into the steering wheel to satisfy this and to prevent driver injuries, but it prevents the driver's injury in another way in consideration of the malfunction of the airbag or the non-airbag installation.

이러한 방식으로는 조향컬럼의 변형을 이용해 충격을 흡수하는 조향컬럼 충격흡수장치가 있으며, 이는 충돌시 조향컬럼 부위의 변형으로 충격을 흡수·완충하므로, 다양한 방식과 구조로 이루어진다.In this way, there is a steering column shock absorbing device that absorbs the impact by using the deformation of the steering column, which is absorbed and buffered by the deformation of the steering column in the event of a collision, it is made of various ways and structures.

일례로, 플라스틱사출물을 넣어 조향 컬럼쪽에 조립하는 캡슐(Capsule)방식이나, 또는 조향 컬럼쪽에 볼트등으로 밴드를 고정하는 밴드플레이트(Bend Plate)방식이 있으며, 이는 모두 마찰력과 변형을 통해 충격을 흡수·완충함으로써, 조향휠쪽으로 부딪히는 운전자가 조향컬럼으로 인한 부상을 줄일 수 있도록 작용한다.For example, there is a capsule method in which plastic injection is put into a steering column, or a band plate method in which a band is fixed to a steering column by bolts, all of which absorb shock through friction and deformation. By mitigating, the driver hits the steering wheel to reduce the injury caused by the steering column.

실제적으로는 다른 다양한 조건인 운전자중량과, 충돌속도와, 충돌조건등을 고려해 안전신뢰성을 향상시키도록 2가지 방식을 혼합해 사용되며, 대표적으로 캡슐과 밴드플레이트를 모두 적용한다. In practice, a combination of the two methods is used to improve safety reliability in consideration of various other conditions, such as driver weight, collision speed, and collision conditions. Representatively, both capsules and band plates are applied.

이러한 이중 방식은 캡슐을 조향컬럼의 하우징에 플라스틱 인서트 몰딩으로 고정하고, 다시 충돌흡수용 밴드플레이트를 조립하는 방식으로 구현한다.This dual method is implemented by fixing the capsule to the housing of the steering column with a plastic insert molding, and then assembling the band plate for collision absorption.

도 2는 본 실시예에 따라 조향컬럼하우징의 마운팅블록쪽에 조립된 밴드플레이이트 타입 조향컬럼 충격흡수장치의 구성도를 나타낸다.Figure 2 shows the configuration of the band plate type steering column shock absorbing device assembled on the mounting block side of the steering column housing according to the present embodiment.

도시된 바와 같이, 캡슐밴드플레이트(1)는 캡슐밴드(3)쪽이 조향컬럼하우징에 장착된 마운팅블록(20)의 양쪽에 형성된 결합단(21)에 끼워져 고정되고, 상기 캡슐밴드(3)에서 일체로 형성된 밴드플레이트(2)가 상기 결합단(21)의 아래쪽에서 돌출된 상태로 조립된다.As shown, the capsule band plate 1 is fixed to the coupling band 21 formed on both sides of the mounting block 20, the capsule band 3 side is mounted to the steering column housing, the capsule band (3) Band plate (2) formed integrally with the assembled in the state protruding from the bottom of the coupling end (21).

본 실시예에서 상기 밴드플레이트(2)는 결합단(21)의 폭을 벗어나 조향휠쪽의 반대쪽으로 돌출된 길이를 갖는데, 이는 충격으로 밀려날 때 접촉변형되면서 출격을 흡수하기 위한 것으로, 밴드플레이트 타입 충격흡수장치에서 구현되는 고유작용이다.In this embodiment, the band plate (2) has a length protruding out of the width of the coupling end 21 to the opposite side of the steering wheel, which is to absorb the outgoing contact deformation when pushed out of the impact, band plate type impact It is a unique action implemented in an absorber.

본 실시예에서 상기 캡슐밴드(3)는 결합단(21)의 하면으로 하단판(4)이 위치되고, 결합단(21)의 상면으로 상단판(5)이 위치되고, 상기 하단판(4)과 상단판(5)의 가이드홀(4a,5a)이 결합단(21)에 뚫린 체결홀(22)을 관통한 볼트로 고정된 상태로 조립된다.In the present embodiment, the capsule band 3 has a lower plate 4 positioned on the lower surface of the coupling end 21, an upper plate 5 positioned on the upper surface of the coupling end 21, and the lower plate 4. ) And the guide holes 4a and 5a of the top plate 5 are assembled in a fixed state with bolts passing through the fastening holes 22 drilled in the coupling end 21.

또한, 도1(나)에 도시된 바와 같이, 상기 캡슐밴드(3)는 엠보돌기(10)를 통해 결합단(21)의 엠보홈(23)과 결합됨으로써, 충격에 대한 마찰저항을 높이게 된다.In addition, as shown in Figure 1 (b), the capsule band 3 is coupled to the embossed groove 23 of the coupling end 21 through the embossed projection 10, thereby increasing the frictional resistance to impact. .

본 실시예에 따른 캡슐밴드플레이트(1)는 전달되는 충격크기가 작으면 밴드플레이트(2)쪽을 통한 충격흡수작용이 일어나는데, 이는 충격이 밴드플레이트(2)쪽에서 모두 흡수되어 캡슐밴드(3)쪽까지 전달되지 않음에 기인한다.In the capsule band plate 1 according to the present embodiment, when the impact size is small, the shock absorbing action occurs through the band plate 2 side, which is absorbed by the band plate 2 side, so that the capsule band 3 is absorbed. Due to not being delivered to the side.

하지만, 충격크기가 클 땐 밴드플레이트(2)쪽에 전달된 충격으로 캡슐밴드(3)쪽에서 볼트파손에 의한 충격흡수와 더불어 엠보돌기(10)쪽 마찰에 의한 부가적인 충격완충작용이 일어난다.However, when the impact size is large, the shock transmitted to the band plate (2) toward the capsule band (3) side of the shock absorption due to the bolt damage and the additional impact buffering action by the friction of the embossed projection (10) occurs.

상기와 같은 엠보돌기(10)를 통한 작용은 도 2(나)와 같이, 상기 엠보돌기(10)가 결합단(21)의 엠보홈(23)에 끼워진 상태에서 빠져나갈 때 발생하는 마찰력 작용을 통해 구현됨을 의미한다. The action through the embossing protrusion 10 as described above is the friction force action generated when the embossing protrusion 10 exits from being fitted in the emboss groove 23 of the coupling end 21 as shown in FIG. Implemented through

이와 같이 본 실시예에 따른 캡슐밴드플레이트(1)가 캡슐에 의한 충격흡수작용을 갖는 캡슐밴드(2)와, 밴드플레이트에 의한 충격흡수작용을 갖는 밴드플레이트(3)를 일체화해 충격완충을 이중으로 구현함으로써, 운전자중량과, 충돌속도와, 충돌조건등과 같이 다른 다양한 조건에서도 안전신뢰성을 크게 높일 수 있게 된다.
As described above, the capsule band plate 1 according to the present embodiment integrates the capsule band 2 having the shock absorbing action by the capsule and the band plate 3 having the shock absorbing action by the band plate to double the impact buffer. By implementing this, safety reliability can be greatly increased even under various other conditions such as driver weight, collision speed, and collision conditions.
