Description
본 고안은 자동차의 범퍼 구조에 관한 것으로서, 특히 충돌할 때 차체가 받는 충격력의 흡수 및 완충 성능을 향상시켜, 차체의 손상을 감소하고, 탑승자의 안전을 보호할 수 있도록 하는 에어 완충수단이 구비된 범퍼에 관한 것이다.The present invention relates to a bumper structure of an automobile, and in particular, to improve the absorption and cushioning performance of the impact force received by the vehicle when it collides, it is equipped with air cushion means to reduce the damage of the vehicle body and protect the safety of the occupants It's about the bumper.
도 1 에 상세하게 도시된 바와 같이, 자동차의 범퍼(1)는 프론트 및 리어쪽 차체(3)에 설치되어, 차량의 추돌시 발생되는 충격력으로부터 차체 및 탑승자를 보호한다.As shown in detail in FIG. 1, the bumper 1 of the vehicle is installed in the front and rear vehicle bodies 3 to protect the vehicle body and the occupant from the impact force generated when the vehicle crashes.
이러한 범퍼는 외장재인 페이셔와, 충격에너지 흡수재인 완충부재 및, 큰 충격에너지를 흡수하며 차체에 고정되는 보강부재의 3부분으로 구분된다.The bumper is divided into three parts: a facer, which is an exterior material, a buffer member, which is an impact energy absorber, and a reinforcement member that absorbs large impact energy and is fixed to a vehicle body.
페이셔는 범퍼의 최외곽에 위치되어 외장을 이루는 부분으로 플라스틱 체결구에 의해 보강부재에 고정되며, 통상 폴리프로필렌 합성수지로 제조된다.The facer is positioned at the outermost part of the bumper to form an exterior and is fixed to the reinforcing member by a plastic fastener, and is usually made of polypropylene synthetic resin.
완충부재는 페이셔의 내부와 보강부재의 외면과의 사이에 부착되는 것으로, 통상 AZDEL(폴리 프로필렌+강화성유)의 발포체나 하니컴의 구조로 제조된다.The shock absorbing member is attached between the inside of the facer and the outer surface of the reinforcing member, and is usually manufactured in the structure of a foam or honeycomb of AZDEL (polypropylene + reinforcing oil).
보강부재는 범퍼의 구조물로서 완충부재와 페이셔를 차체에 고정하며, 큰 충격에너지를 흡수한다.The reinforcing member is a bumper structure that fixes the cushioning member and the facer to the vehicle body and absorbs a large impact energy.
종래 기술에서 설명된 범퍼에 있어서, 종래의 완충부재는 합성수지로 제조된 하니컴의 경우, 1회의 충격으로 재 사용이 불가능하게 변형되는 문제점이 있다.In the bumper described in the prior art, the conventional shock absorbing member is a honeycomb made of a synthetic resin, there is a problem that can not be reused in one impact.
또한, 발포체인 경우 범퍼는 충격 흡수율이 부족하여, 고속 주행시의 추돌과 같은 큰 충격에 약한 문제점이 있다.In addition, in the case of the foam, the bumper is insufficient in the shock absorption rate, there is a weak problem in large impacts such as collision during high-speed running.
따라서, 종래에는 차량의 추돌사고시 차체의 손상 및 탑승자의 부상 정도를 크게 하는 문제점이 있다.Therefore, in the related art, there is a problem of increasing the damage of the vehicle body and the degree of injury of the occupant during the collision of the vehicle.
본 고안은 상술한 종래 기술의 문제점을 해소하기 위한 목적에서 제안된 것으로서, 차량의 충돌시 차체가 받는 충격력의 완충 및 흡수 성능을 향상시켜, 탑승자와 차체를 보호할 수 있도록 하는 자동차의 범퍼 구조를 제공한다.The present invention has been proposed in order to solve the problems of the prior art described above, and improves the shock absorbing and absorbing performance of the impact force received by the vehicle in the event of a collision, thereby improving the bumper structure of the vehicle to protect the occupants and the vehicle body. to provide.

상술한 목적을 실현하기 위한 수단으로서, 본 고안의 구성을 첨부된 도면에 의거하여 보다 상세하게 설명한다.As means for realizing the above object, the configuration of the present invention will be described in more detail with reference to the accompanying drawings.
도 2 는 본 실시예에 관련된 자동차의 범퍼 구조를 보인 것으로서, 도 1 의 A-A 선을 절취 도시한 상태의 단면도이다.FIG. 2 is a cross-sectional view illustrating a bumper structure of the vehicle according to the present embodiment, and is taken along line A-A of FIG. 1.
본 실시예를 설명함에 있어, 종래 기술에서 인용된 도면과 동일한 본 실시예의 구성에 대해서는 설명의 명료성을 위해 동일한 부호를 사용한다.In describing the present embodiment, the same reference numerals are used for the clarity of description for the configuration of the present embodiment that is the same as the drawings cited in the prior art.
도면에서의 설명 부호 (1)은 범퍼 전체를 지칭한다.Reference numeral 1 in the drawings refers to the entire bumper.
범퍼(1)의 최전방 혹은 최후방에는 외장면을 형성하는 페이셔(5)가 설치되고, 그 페이셔(5)는 빔(beam)상의 보강부재(도시생략)와 함께 프론트 및 리어쪽 차체에 설치된다.The front or rear of the bumper 1 is provided with a facer 5 for forming an exterior surface, and the facer 5 is provided on the front and rear bodies together with a reinforcing member (not shown) on the beam. Is installed.
페이셔(5)와 보강부재의 사이에는 차체의 추돌시 그 충격에너지를 흡수하기 위한, 완충수단이 설치된다.A buffer means is provided between the facer 5 and the reinforcing member to absorb the impact energy when the vehicle body collides.
이러한 구성들을 포함하는 범퍼 구조에 있어서, 본 실시예에서는 상기 완충수단으로서 페이셔(5)에서 차체의 리어쪽으로 연결된 피스톤(7)과, 상기 피스톤(7)이 삽입되어 직선 왕복운동되는 에어 실린더(9)와, 그 에어 실린더(9)가 삽입되어 직선 왕복운동되며 보강부재에 설치된 유압 실린더(11)를 포함하여 구성된다.In the bumper structure including such configurations, in the present embodiment, the piston 7 is connected to the rear of the vehicle body in the facer 5 as the shock absorber, and the air cylinder in which the piston 7 is inserted and reciprocates linearly. 9) and a hydraulic cylinder 11 inserted into the air cylinder 9 to linearly reciprocate and installed in the reinforcing member.
이상에서 설명하고 있는 구성에 의한 본 실시예의 작용은 다음과 같다.The operation of this embodiment by the configuration described above is as follows.
즉, 차량의 추돌에 의해 소정의 충격력이 가해지면, 페이셔(5)가 피스톤(7)을 가압하고, 그 피스톤(7)에 의해 에어 실린더(9)의 내부에 충진된 에어가 압축되면서, 충격력이 1차적으로 흡수 및 완충된다.That is, when a predetermined impact force is applied by the collision of the vehicle, the pacer 5 presses the piston 7, and the air filled in the inside of the air cylinder 9 is compressed by the piston 7, Impact force is primarily absorbed and cushioned.
또한, 상기 에어 실린더(9)는 유압 실린더(11)의 내부에 충진된 유체를 압착하면서, 충격력이 2차적으로 흡수 및 완충된다.In addition, the air cylinder 9, while compressing the fluid filled in the hydraulic cylinder 11, the impact force is secondarily absorbed and buffered.
이상에서 설명된 구성 및 작용을 통하여 알 수 있듯이, 본 고안에 의한 자동차의 범퍼 구조는 종래 기술의 문제점을 실질적으로 해소한다.As can be seen through the configuration and operation described above, the bumper structure of the vehicle according to the present invention substantially solves the problems of the prior art.
즉, 본 고안은 차량의 추돌에 의해 차체 및 탑승자에게로 전달되는 충격력을 2차에 걸쳐 흡수 및 완충하므로서, 차체 및 탑승자의 손상을 퍼펙트하게 감소시키는 효과를 얻을 수 있다.That is, the present invention absorbs and buffers the impact force transmitted to the vehicle body and the occupant over two times by the collision of the vehicle, thereby achieving an effect of perfectly reducing the damage of the vehicle body and the occupant.
또한, 접촉사고와 같은 미세한 충격에 대하여, 에어의 완충 작용으로, 변형이 방지되는 효과도 아울러 얻을 수 있다.In addition, the effect that the deformation is prevented by the buffering action of air against minute impact such as a contact accident can also be obtained.
한편, 본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 실용신안등록 청구의 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.On the other hand, the present invention is not limited to the above-described specific preferred embodiment, any person having ordinary knowledge in the field to which the subject innovation belongs without departing from the gist of the subject innovation claimed in the utility model registration claims Modifications may be made.
