Description

차량용 범퍼 결합 구조 {Vehicle bumper coupling structure}Vehicle bumper coupling structure [0001]

본 발명은 차량용 범퍼 결합 구조에 관한 것으로, 더욱 상세하게는 범퍼의 상단에 마련된 결합부를 차체의 고정브래킷에 별도의 체결부재 없이 고정할 수 있는 차량용 범퍼 결합 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bumper coupling structure for a vehicle, and more particularly to a bumper coupling structure for a vehicle which can fix a coupling portion provided at an upper end of a bumper to a fixing bracket of a vehicle body without a separate coupling member.

통상적으로, 차량은 차체와 섀시로 크게 구분된다. 차체는 엔진을 비롯하여 차실, 하대, 기관실, 트렁크실, 펜더 등으로 구성되어 운전자나 적재화물에 필요한 공간을 제공하며, 다수의 패널을 용접이나 볼트 등의 결합을 통해 차량의 외형을 형성한다. Generally, a vehicle is largely divided into a vehicle body and a chassis. The body is made up of the engine, the car, the undercarriage, the engine room, the trunk room, the fender, etc. to provide the space required for the driver or the cargo, and the outer shape of the vehicle is formed by joining a plurality of panels with welding or bolts.

또한, 차체는 사고로 인한 충돌 및 전복시 외부 충격으로부터 차량 내의 탑승자를 보호할 수 있을 정도의 충분한 강성을 구비해야 하며, 이와 함께 충격을 단계적으로 흡수하여 승객에게 전달되는 힘을 최소화함으로써 상해 정도를 줄일 수 있도록 구성된다.In addition, the vehicle body should have enough rigidity to protect the passenger in the vehicle from an external impact in case of an accidental collision or rollover, and by absorbing the impact step by step to minimize the power transmitted to the passenger, .

이렇게 차체에 전달되는 충격을 단계적으로 흡수하여 승객에게 전달되는 충격을 경감할 수 있도록 차량의 전면과 후면부는 크러스존(Crush zone)이 구비된 크러셔블 보디(Crushable body)로 이루어져 있으며, 오늘날 대부분의 자동차는 이러한 구조를 갖추고 있다. The front and rear parts of the vehicle are made of a crushable body equipped with a crush zone so that the impact transmitted to the vehicle body can be absorbed in a stepwise fashion to alleviate the impact to passengers. Of cars have this structure.

특히, 차량의 전방과 후방에는 범퍼가 장착되어 차량의 전방 충돌 및 후방충돌 사고 발생시 그 충격을 흡수하여 차체로 전달되는 충격을 최소화함으로써, 운전자를 비롯한 탑승객을 보호함은 물론 엔진을 비롯한 차량 각부의 차체를 보호하는 역할을 수행한다.Particularly, a bumper is mounted on the front and rear of the vehicle to absorb a shock of a front collision or a rear collision of the vehicle to minimize impact transmitted to the vehicle body, thereby protecting the driver and other passengers, And protects the vehicle body.

이러한 종래의 범퍼 결합 구조가 도 1에 도시되어 있다. Such a conventional bumper coupling structure is shown in Fig.

도시된 바와 같이, 종래의 범퍼 결합 구조는, 범퍼(10)의 상단부에 체결홀(11a)이 형성된 결합부재(11)가 마련되고, 이 결합부재(11)가 차체(20)에 구비되는 고정브래킷(21)에 별도의 체결부재(30)로 체결되어 고정되는 구조이다.As shown in the drawings, the conventional bumper coupling structure is provided with a coupling member 11 having a coupling hole 11a formed at the upper end of the bumper 10, and the coupling member 11 is fixed to the vehicle body 20 And is fastened to the bracket 21 with another fastening member 30 and fixed.

결합부재(11)는 곡면형상으로 된 범퍼(10)의 상단에 차량의 후방 쪽으로 돌출되되 수평으로 돌출 형성된다. 그리고 결합부재(11)에는 별도의 체결부재(30)인 볼트가 끼워지는 복수의 체결홀(11a)이 형성된다.The coupling member 11 protrudes horizontally from the upper end of the curved bumper 10 toward the rear of the vehicle. The coupling member 11 is formed with a plurality of coupling holes 11a through which bolts, which are separate coupling members 30, are inserted.

차체(20)에는 범퍼(10)를 결합하기 위한 고정브래킷(21)이 마련되되, 이 고정브래킷(21)은 일정길이의 판부재가 절곡되어 'ㄱ' 형상으로 형성된다. 그리고 고정브래킷(21)의 상단부인 수평부에 체결부재(30)가 끼워지는 다른 체결홀(21a)이 형성된다. 여기서, 고정브래킷(21)은 결합부재(11)에 형성된 체결홀(11a)과 같은 숫자로 구성되며 각 체결홀(11a)(21a)에 대응되도록 구성된다.The vehicle body 20 is provided with a fixing bracket 21 for coupling the bumper 10, and the fixing bracket 21 is formed in a shape of a plate by bending a plate member of a predetermined length. Another fastening hole 21a in which the fastening member 30 is fitted is formed in the horizontal part of the upper end of the fastening bracket 21. Here, the fixing bracket 21 is formed in the same number as the fastening hole 11a formed in the fastening member 11, and is configured to correspond to each fastening hole 11a, 21a.

따라서, 고정브래킷(21)의 수평부인 상단부의 윗면에 결합부재(11)가 올려진 후에 볼트가 결합부재(11)의 체결홀(11a)과 고정브래킷(21)의 체결홀(21a)에 끼워져 체결되는 것이다. The bolt is inserted into the fastening hole 11a of the fastening member 11 and the fastening hole 21a of the fastening bracket 21 after the fastening member 11 is mounted on the upper surface of the upper end of the fastening bracket 21 It is concluded.

상기와 같은 종래의 범퍼 결합 구조는, 범퍼(10)가 별도의 체결부재(30)에 의해 차체(20)에 구비되는 고정브래킷(21)에 고정되도록 구성된다.The conventional bumper coupling structure is configured such that the bumper 10 is fixed to the fixing bracket 21 provided on the vehicle body 20 by a separate fastening member 30. [

따라서, 범퍼(10)를 결합하는 별도의 체결부재(30)가 별도의 부품으로서 범퍼(10)와 별도로 관리되어야 하고, 체결부재(30)를 체결하기 위해서는 체결공구를 필요로 하게 됨으로써 조립 작업에 시간이 소요되는 문제점과 체결부재(30)를 분실하게 되는 문제점이 있었다.Therefore, the separate fastening member 30 for coupling the bumper 10 needs to be managed separately from the bumper 10 as a separate component. In order to fasten the fastening member 30, a fastening tool is required, There is a problem that it takes time and the fastening member 30 is lost.

지지리브(311)는 고정부(310)의 밑면에 고정부(310)의 길이 방향으로 형성되되, 다수가 일정간격으로 이격되어 마련된다.The supporting ribs 311 are formed on the bottom surface of the fixing portion 310 in the longitudinal direction of the fixing portion 310 and are spaced apart at a predetermined distance.

상기와 같은 구성된 본 발명의 일실시예에 따른 차량용 범퍼 결합 구조에 대한 작용을 간략하게 설명하기로 한다. The operation of the bumper coupling structure for a vehicle according to an embodiment of the present invention will be briefly described.

먼저, 차체에 고정브래킷(110)의 수직부(112)가 볼트와 같은 체결부재로 고정되어 있으며, 범퍼 결합부재(210)에 고정부(310)가 사출 성형시 일체로 형성된다.First, a vertical portion 112 of a fixing bracket 110 is fixed to a vehicle body by a fastening member such as a bolt, and a fixing portion 310 is formed integrally with the bumper coupling member 210 during injection molding.

또한, 범퍼 결합부재(210)도 범퍼(200)의 상단에 일체로 성형되거나 별도의 체결부재로 고정되어 마련된다. Further, the bumper coupling member 210 is integrally formed on the upper end of the bumper 200 or is fixed by a separate fastening member.

따라서, 범퍼(200)를 차체(100)에 조립하기 위해서는 범퍼 결합부재(210)와 고정브래킷(110)에 마련된 체결수단(300)을 사용하여야 한다.Therefore, in order to assemble the bumper 200 to the vehicle body 100, the bumper coupling member 210 and the fastening means 300 provided on the fastening bracket 110 should be used.

먼저, 범퍼를 차체에 결합하기 전에 체결수단(300)의 고정부(310)를 범퍼 결합부재(210)에 대해 접어서 범퍼 결합부재(210)의 밑면에 이탈방지부(340)로 고정시킨다. 즉, 고정부(310)의 밑면에 형성된 이탈방지용 돌기(341)를 범퍼 결합부재(210)의 밑면에 형성된 끼움홈(342)에 끼워 고정하여 고정부(310)가 범퍼 결합부재(210)의 밑면에 밀착되어 떨어지지 않도록 한다. First, before the bumper is coupled to the vehicle body, the fixing portion 310 of the fastening means 300 is folded with respect to the bumper coupling member 210 and fixed to the bottom of the bumper coupling member 210 with the anti-departure portion 340. The detent protrusion 341 formed on the bottom of the fixing part 310 is fitted and fixed in the fitting groove 342 formed on the bottom of the bumper coupling member 210 so that the fixing part 310 is fixed to the bumper coupling member 210 Make sure that it does not fall off the bottom surface.

이후에, 범퍼 결합부재(210)가 마련된 범퍼를 차체 쪽으로 이동시킨 후에 고정부(310)에 형성된 고정후크(320)를 고정브래킷(110)의 고정홀(115)에 일치시킨 후에 범퍼 결합부재를 위에서 눌러 고정하게 된다. Thereafter, after the bumper provided with the bumper coupling member 210 is moved toward the vehicle body, the fixing hook 320 formed on the fixing portion 310 is aligned with the fixing hole 115 of the fixing bracket 110, And is fixed by pressing it from above.

그러면, 고정후크(320)가 고정홀(115)에 끼워져 고정홀(115)의 하측 가장자리에 걸려서 고정되는 것이다. Then, the fixing hook 320 is inserted into the fixing hole 115 and is caught and fixed to the lower edge of the fixing hole 115.

상술한 바와 같이 본 발명은 도면에 도시된 실시 예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 기술적 보호범위는 아래의 특허청구범위에 의해서 정하여져야 할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is understandable.
