Description

리어범퍼의 차체 고정구조{REAR BUMPER MOUNTING IMPROVEMENT}REAR BUMPER MOUNTING IMPROVEMENT}

본 발명은 리어범퍼의 차체 고정구조에 관한 것으로 더욱 상세하게는 리어범퍼의 사이드측의 'L 자형' 부분을 차체의 아우터 프레임에 직접 취부할 수 있도록 하여 외관을 향상시키고 차체와 리어범퍼사이의 단차를 발생시키지 않도록 발명된것이다.The present invention relates to a vehicle body fixing structure of the rear bumper, and more particularly, the 'L-shaped' portion on the side of the rear bumper can be directly mounted on the outer frame of the vehicle body, thereby improving the appearance and the step between the vehicle body and the rear bumper. Invented so as not to generate.

범퍼는 자동차의 앞뒤에서 보디를 보호하기 위하여 설치되어 있는 장치로서 부딪혔을 때 그 충격을 흡수하는 역할을 한다.The bumper is a device installed to protect the body from the front and the back of the vehicle, and absorbs the shock when it is hit.

종래의 범퍼는 강철재료 보디에서 약간 튀어나온 정도였으나, 미국에서 대형 범퍼가 사용되게 되어 현재는 에너지 흡수 범퍼라고 불리우는 것이 일반화되어 있다.Conventional bumpers were only slightly protruding from the steel body, but large bumpers have been used in the United States and are now commonly referred to as energy absorbing bumpers.

상기 에너지 흡수 범퍼는 우레탄등의 재질로 제조되며, 충격흡수의 정도가 커져 있으나 동시에 보디와 일체화한 디자인 등에 의하여, 장식을 겸한 부품으로 되어가고 있다.The energy absorbing bumper is made of a material such as urethane, and the degree of shock absorption is increased, but at the same time, the energy absorbing bumper has become a decorative part by a design integrated with a body.

에너지 흡수 범퍼(Energy Aborbent Bumper)는 저속으로 충돌했을 경우 차체가 손상받지 않도록 기계적 에너지를 흡수하는 범퍼이며, 북미에서는 8 Km/h 충돌에너지 흡수범퍼의 설치가 법으로 의무화되어 있었으나, 현재는 4Km/h로 완화되었다.Energy Aborbent Bumper is a bumper that absorbs mechanical energy in order to avoid damage to the body when collided at low speed. In North America, the installation of 8 Km / h collision energy absorption bumper is required by law. relaxed to h.

각 메이커가 여러가지 범퍼를 개발하고 있으나, 크게 나누어 우레탄등의 완충재를 쓰는 것(예; 우레탄 리어범퍼)과 오일의 점도를 이용한 것(예; 메나스코식 리어범퍼)이 있다.Although each manufacturer has developed various bumpers, there are two types of bumpers, such as urethane buffers (e.g. urethane rear bumpers) and oil viscosity (e.g. Menasco rear bumpers).

상기와 같은 범퍼는 차체 전면에 부착되는 프론트 범퍼(Front Bumper)와 후면에 부착되는 리어범퍼(Rear Bumper)로 구분된다.The bumper is classified into a front bumper attached to the front of the vehicle body and a rear bumper attached to the rear of the vehicle body.

그리고, 상기 리어범퍼를 차체에 고정시키는 구조는 도 1 에서 도시한 바와 같이 리어범퍼(10') 내측면에 차체를 이루는 플레이트(20')의 외측면과 밀착되도록돌출된 보스(11')를 형성하여 스크류 등과 같은 체결수단(40')을 상기 플레이트 내측면에서 보스(11')로 관통하여 체결함으로서 고정시켰다.In addition, the structure of fixing the rear bumper to the vehicle body has a boss 11 'protruded to be in close contact with the outer surface of the plate 20' forming the vehicle body on the inner surface of the rear bumper 10 'as shown in FIG. It was formed by fixing the fastening means 40 'such as a screw penetrating through the boss 11' from the inner surface of the plate.

그러나, 상기와 같이 리어범퍼가 플레이트에만 고정되어 있고, 아우터 프레임에 직접 취부되지 않으므로 리어범퍼의 끝단과 아우터 프레임의 사이드측 간에 단차(t)가 발생되는 폐단이 있었던 것이다.However, as described above, since the rear bumper is fixed only to the plate and is not directly mounted on the outer frame, there is a closed end at which a step t is generated between the end of the rear bumper and the side side of the outer frame.

또한, 리어범퍼의 내측면에 스크류가 관통되어 체결되는 보스가 형성된 부분의 외측면에 싱크 마크(Sink Mark)가 발생되어 외관이 저하되는 문제점이 있었던 것이다.In addition, a sink mark is generated on the outer surface of the boss where the screw is penetrated to the inner surface of the rear bumper and the appearance is deteriorated.

본 발명의 목적은 리어범퍼를 체결수단을 이용하여 차체를 이루는 플레이트와 아우터 플레이트를 관통하여 고정하므로서 리어범퍼를 차체에 밀착시킬 수 있으며 리어범퍼 외측면에 싱크 마크가 생기는 것을 방지하여 품질을 증대시키는 리어범퍼의 차체 고정구조를 제공하는 데 있다.An object of the present invention is to fix the rear bumper through the plate and the outer plate forming the vehicle body by using the fastening means to closely adhere the rear bumper to the vehicle body and to prevent the occurrence of the sink mark on the outer surface of the rear bumper to increase the quality It is to provide a body fixing structure of the rear bumper.

이러한 본 발명의 목적은 리어범퍼(10)를 차체에 고정함에 있어서;The object of this invention is to secure the rear bumper 10 to the vehicle body;

리어범퍼(10)의 L자형 파트부(12)를 차체를 이루는 플레이트(20)와 아우터 프레임(30) 사이에 결합하고, 상기 플레이트(20)의 외측면으로 부터 상기 아우터 프레임(30) 내측으로 체결수단(40)을 관통시켜 주는 것에 의해 달성된다.The L-shaped part 12 of the rear bumper 10 is coupled between the plate 20 constituting the vehicle body and the outer frame 30, and from the outer surface of the plate 20 to the inner frame 30. It is achieved by penetrating the fastening means 40.

즉, 체결수단(40)을 관통시켜 리어범퍼(10)의 L자형 파트부(12)를 플레이트(20) 및 아우터 프레임(30)에 직접 체결하여 리어범퍼(10)가 차체에 고정되므로 리어범퍼(10) 사이드측의 L자형 파트부(12)를 차체에 면착시킬 수 있는 것이다.That is, the rear bumper 10 is fixed to the vehicle body by directly fastening the L-shaped part 12 of the rear bumper 10 to the plate 20 and the outer frame 30 by penetrating the fastening means 40. (10) The L-shaped part 12 on the side can be attached to the vehicle body.

본 발명의 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

도 2와 도 3에서 도시한 바와 같이 리어범퍼(10)가 설치되는 차체 패널 구조는 누수 및 소음 방지를 위해 트렁크 룸 내측으로 플레이트(20), 아우터 프레임등(30)으로 다중겹으로 구성되어 있다.As shown in FIG. 2 and FIG. 3, the vehicle body panel structure in which the rear bumper 10 is installed is composed of multiple layers including a plate 20 and an outer frame 30 inside the trunk room to prevent leakage and noise. .

즉, 상기 플레이트(20)와 아우터 프레임(30) 사이에 끝단이 절곡형성된 리어범퍼(10)의 L자형 파트부(12)를 결합한다.That is, the L-shaped part portion 12 of the rear bumper 10 having an end bent is coupled between the plate 20 and the outer frame 30.

그리고, 플레이트(20)의 외측면에서 웰드핀(Weld-Pin)(41)을 아우터 프레임(30)의 내측으로 돌출되도록 관통하여 체결시켜 고정시키는 것이다.Then, the weld pin (Weld-Pin) (41) in the outer surface of the plate 20 is to be fixed by penetrating through so as to protrude into the outer frame (30).

한편, 상기 플레이트(20)와 리어범퍼(10)의 L자형 파트부(12) 및 아우터 프레임(30)을 체결한 웰드핀(41)의 돌출부에는 그로밋(Grommet)(42)을 결합하여 상기 웰드핀(41)의 돌출부분을 감싸며 지지하도록 하여 견고히 고정될 수 있도록 하고, 아우터 프레임(30)의 관통부분을 보호함과 아울러 방수, 방진효과를 증대시킬 수 있는 것이다.On the other hand, by connecting the grommet (42) to the protrusion of the weld pin 41 to which the L-shaped part portion 12 and the outer frame 30 of the plate 20 and the rear bumper 10 is coupled, the weld The protrusions of the pins 41 may be wrapped and supported to be firmly fixed, and the waterproof and dustproof effects may be increased while protecting the through parts of the outer frame 30.

이러한 본 발명의 구성에 의하면, 리어범퍼(10)의 L자형 파트부(12)가 차체(1)의 플레이트(20)와 아우터 플레이트(30) 양측에 모두 체결되어 고정되므로, 리어범퍼(10)가 차체에 면착되어 리어범퍼(10)와 차체사이에 발생되는 단차를 방지할 수 있는 것이다.According to the configuration of the present invention, since the L-shaped part 12 of the rear bumper 10 is fastened and fixed to both sides of the plate 20 and the outer plate 30 of the vehicle body 1, the rear bumper 10 Is attached to the vehicle body to prevent the step that is generated between the rear bumper 10 and the vehicle body.

또한, 리어범퍼(10)를 차체에 더욱 견고히 고정할 수 있는 것이다.In addition, the rear bumper 10 can be more firmly fixed to the vehicle body.

따라서, 차량의 미관과 품질을 향상시킬 수 있는 매우 유용한 발명인 것이다.Therefore, it is a very useful invention that can improve the aesthetics and quality of the vehicle.
