이들 도면에 도시된 바와 같이 본 발명의 실시예에 따른 자동차의 범퍼 마운팅구조는 범퍼커버(100)의 후방에 구비된 한쌍의 상단걸림부(210), 범퍼커버(100)의 후방에 구비되되 한쌍의 상단걸림부(210)의 좌우방향 외측으로 이격되어 구비된 한쌍의 하단걸림부(410), 상측단의 양측이 상단걸림부(210)에 결합되며 하측단의 양측이 하단걸림부(410)에 결합되고, 범퍼커버(100)의 후방면에 장착되어 차량 충돌시 충격을 흡수하는 업소버(300)를 포함하는 것을 특징으로 한다.As shown in these drawings, the bumper mounting structure of a vehicle according to an embodiment of the present invention is provided with a pair of upper engaging portions 210 provided at the rear of the bumper cover 100, and provided at the rear of the bumper cover 100 A pair of lower engaging portions 410 provided spaced apart from the left and right of the upper engaging portion 210 of the upper end, both sides of the upper end are coupled to the upper engaging portion 210, and both sides of the lower end are lower engaging portions 410 It is coupled to, and is mounted on the rear surface of the bumper cover 100, characterized in that it comprises an absorber 300 for absorbing the impact when a vehicle collision.

범퍼커버(100)는 차량의 전방에 구비되어 범퍼 외관을 형성하며, 범퍼커버(100)의 후방면에는 업소버(300) 등이 결합되어 차량 충돌시 가해지는 충격을 흡수한다.The bumper cover 100 is provided in the front of the vehicle to form the exterior of the bumper, and an absorber 300, etc. are coupled to the rear surface of the bumper cover 100 to absorb the shock applied during a vehicle collision.

업소버(300)는 자동차의 폭방향으로 길게 형성되어 범퍼커버(100) 후방면에 구비되는 상단걸림부(210)와 하단걸림부(410)에 의해 마운팅되며, 차량 충돌시에 가해지는 충격을 흡수하여 운전자에게 전달되는 충격을 감소시키는 역할을 한다.The absorber 300 is formed long in the width direction of the vehicle and is mounted by the upper engaging portion 210 and the lower engaging portion 410 provided on the rear surface of the bumper cover 100, and absorbs the impact applied when a vehicle crashes. Thus, it plays a role in reducing the shock transmitted to the driver.

상단걸림부(210)는 업소버(300)의 상측을 감싸도록 절곡 형성되어 범퍼커버(100)의 후방에 한쌍으로 구비된다.The upper engaging portion 210 is formed to be bent to surround the upper side of the absorber 300 and provided in a pair at the rear of the bumper cover 100.

하단걸림부(410)는 업소버(300)의 하측을 감싸도록 절곡 형성되어 범퍼커버(100)의 후방에 한쌍으로 구비되는데, 한쌍의 상단걸림부(210)의 좌우방향 외측으로 이격되어 구비된다.The lower engaging portions 410 are formed to be bent to surround the lower side of the absorber 300 and provided as a pair at the rear of the bumper cover 100, and are spaced apart from each other in the left and right directions of the pair of upper engaging portions 210.

이에 따라 업소버(300)는 상측을 상단걸림부(210)에 삽입하여 고정시킨 후에 길이방향 단부를 벤딩시켜 하측을 하단걸림부(410)에 삽입하여 고정시킴으로써, 범퍼커버(100)의 후방에 장착된다.Accordingly, the absorber 300 is mounted on the rear of the bumper cover 100 by inserting and fixing the upper side into the upper engaging portion 210 and then bending the longitudinal end to insert the lower side into the lower engaging portion 410 and fixing it. do.

이때, 상단걸림부(210)와 하단걸림부(410)는 적어도 200mm 이상의 좌우방향 이격거리만큼 이격되게 구비되어 업소버(300)의 상측 두곳이 상단걸림부(210)에 삽입 고정된 상태에서 길이방향 단부를 벤딩하여 하단걸림부(410)에 삽입 고정시킬 수 있는 구조가 된다.At this time, the upper engaging portion 210 and the lower engaging portion 410 are provided to be spaced apart by at least 200 mm or more in the horizontal direction, so that the upper two places of the absorber 300 are inserted into the upper engaging portion 210 and fixed in the longitudinal direction. It has a structure that can be inserted and fixed to the lower engaging portion 410 by bending the end.

즉, 업소버(300)는 상단걸림부(210)와 하단걸림부(410)에 끼움결합되는 것으로, 상단걸림부(210)와 하단걸림부(410)는 상하방향으로 업소버(300)의 상하방향 길이만큼 이격되는 위치에 구비되어 있기 때문에, 상단걸림부(210)와 하단걸림부(410)가 좌우방향으로 이격되어 있어야 업소버(300)의 길이방향 단부를 벤딩하여 조립할 수 있는 것이다. That is, the absorber 300 is fitted to the upper engaging portion 210 and the lower engaging portion 410, and the upper engaging portion 210 and the lower engaging portion 410 are vertically arranged in the vertical direction of the absorber 300 Since it is provided at a position spaced apart by the length, the upper engaging portion 210 and the lower engaging portion 410 must be spaced apart from each other in the left-right direction so that the longitudinal end of the absorber 300 can be bent and assembled.

이와 같이 업소버(300)가 상단걸림부(210)와 하단걸림부(410)에 각각 끼움 결합됨에 따라 업소버(300)를 범퍼커버(100)에 장착시키기 위한 별도 부품이 필요 없게 되며, 뿐만 아니라 종래에 조립되던 별도 부품의 조립과정을 없앨 수 조립시간이 단축되고, 별도 부품의 제작비용 및 조립비용을 절약할 수 있게 된다.In this way, as the absorber 300 is fitted to the upper engaging portion 210 and the lower engaging portion 410, respectively, there is no need for a separate part for mounting the absorber 300 to the bumper cover 100, as well as conventional By eliminating the assembly process of separate parts that were assembled in the assembly, the assembly time is shortened, and the manufacturing cost and assembly cost of the separate parts can be saved.

특히, 상단걸림부(210)는 업소버(300)의 상측에서 범퍼커버(100)에 체결되는 마운팅브라켓(200)에 구비될 수 있으며, 마운팅브라켓(200)의 후방면의 양측에서 돌출되어 업소버(300)의 상측단을 감싸도록 절곡 형성된다. 단, 상단걸림부(210)는 업소버(300)의 상측을 지지해줄 수 있는 범퍼커버(100) 또는 범퍼커버(100)에 부착되는 부품의 어느 위치에든 구비될 수 있다.In particular, the upper engaging portion 210 may be provided on the mounting bracket 200 fastened to the bumper cover 100 from the upper side of the absorber 300, protruding from both sides of the rear surface of the mounting bracket 200, the absorber ( 300) is bent to surround the upper end. However, the upper engaging portion 210 may be provided at any position of the bumper cover 100 capable of supporting the upper side of the absorber 300 or a component attached to the bumper cover 100.

마운팅브라켓(200)은 일예로 범퍼커버(100)의 후방면에 용접 고정되거나 별도 체결부재(미도시)를 이용하여 고정될 수 있다.The mounting bracket 200 may be fixed by welding to the rear surface of the bumper cover 100 or may be fixed using a separate fastening member (not shown).

또한, 하단걸림부(410)는 업소버(300)의 하측에서 상기 범퍼커버(100)에 체결되는 로워커버(400)에 구비될 수 있으며, 로워커버(400)의 상측단의 양측에서 돌출되어 상기 업소버(300)의 하측단을 감싸도록 절곡 형성된다. 단, 하단걸림부(410)는 업소버(300)의 하측을 지지해줄 수 있는 범퍼커버(100) 또는 범퍼커버(100)에 부착되는 부품의 어느 위치에든 구비될 수 있다.In addition, the lower engaging portion 410 may be provided on the lower cover 400 fastened to the bumper cover 100 from the lower side of the absorber 300, protruding from both sides of the upper end of the lower cover 400 It is formed bent to surround the lower end of the absorber 300. However, the lower engaging portion 410 may be provided at any position of the bumper cover 100 that can support the lower side of the absorber 300 or a component attached to the bumper cover 100.

로워커버(400)도 마운팅브라켓(200)의 장착구조와 유사하게 범퍼커버(100)와 용접 고정되거나 별도 체결부재(미도시)를 이용하여 고정될 수 있으며, 범퍼커버(100)의 하단에 위치되어 범퍼 하단의 외관을 형성한다.Similar to the mounting structure of the mounting bracket 200, the lower cover 400 may be welded to the bumper cover 100 or may be fixed using a separate fastening member (not shown), and is located at the bottom of the bumper cover 100 To form the exterior of the bottom of the bumper.
