Abstract

The present invention relates to a structure for reinforcing a side unit of a bumper for a vehicle. On an inner upper side of the bumper (10), a flange (11) is formed to be bent toward one side and to come in contact with a lower surface of a side frame (20). The flange (11) has a fastening hole (12) formed to penetrate, allowing a fastening bolt (30) fastened with the side frame (20) to be inserted to be penetrated. Between the flange (11) and an inner side surface of the bumper (10), a reinforcing rib (13) is formed, so even if an accident occurs on a side surface of the vehicle while the vehicle is driving and an impact is applied to the side unit of the bumper (10), it suppresses the deformation and damage of the flange, which connects the side frame (20) to the side unit of the bumper (10), by the reinforcing rib (13). Accordingly, collision performance is improved, and passengers riding in the vehicle have improved safety. In addition, the side unit of the bumper (10) is suppressed from being separated from the side frame (20), thereby maintaining the exterior aesthetics of the vehicle.

Description

안정성을 향상 시킨 자동차 범퍼의 사이드부 보강기술{anjeongseong-eul hyangsang sikin jadongcha beompeoui saideubu bogang-gisul}Side reinforcement technology of automobile bumpers with improved stability{anjeongseong-eul hyangsang sikin jadongcha beompeoui saideubu bogang-gisul}

본 발명은 자동차용 범퍼의 사이드부 보강구조에 관한 것으로서, 더욱더 상세하게는 차량의 정면과 후면에 설치되는 범퍼의 사이드부가 차량을 운행중 발생하는 접촉사고등에 의해 사이드프레임으로부터 쉽게 분리되는 것이 억제되도록 하는 자동차용 범퍼의 사이드부 보강구조에 관한 것이다.The present invention relates to a reinforcing structure of a side portion of a bumper for a vehicle, and more particularly, the side portion of the bumper installed at the front and rear of the vehicle is prevented from being easily separated from the side frame due to a contact accident occurring while driving the vehicle. It relates to a reinforcement structure of a side part of a bumper for an automobile.

일반적으로 자동차의 전후면에는 차량을 운행중 정면 및 후면에서 충돌사고가 발생하는 경우에도 상기 정면 및 후면에서 발생된 충격에너지를 효과적으로 흡수하여 차실에 탑승한 승원이 부상당하는 것이 억제되도록 하는 전면 범퍼와 후면 범퍼가 차체에 각각 결합되어 있다.In general, the front and rear bumpers and rear bumpers that effectively absorb the impact energy generated from the front and rear sides of a vehicle to prevent injuries to crew members in the vehicle compartment even when a collision occurs from the front and rear while driving the vehicle. Each bumper is attached to the body.

한편, 상기 범퍼의 사이드부에는 도 1에 도시하고 있는 바와 같이, 범퍼(10)의 내측 상부에 일측으로 절곡되어 사이드프레임(20)의 저면에 접하는 플랜지(11)가 형성되고, 상기 플랜지(11)에는 사이드프레임(20)에 체결되는 체결볼트(30)가 관통되게 삽입되도록 하는 체결공(12)이 관통되게 형성되어 있다.On the other hand, the side portion of the bumper, as shown in Figure 1, is bent to one side on the inner upper portion of the bumper 10, a flange 11 in contact with the bottom surface of the side frame 20 is formed, the flange 11 ) Has a fastening hole 12 through which the fastening bolt 30 fastened to the side frame 20 is inserted through.

이러한 종래 범퍼의 사이드부는 범퍼(10)의 상부에 일측으로 절곡되어 형성된 플랜지(11)의 상부면이 사이드프레임(20)의 접하도록 한 상태에서 상기 사이드프레임(20)에 체결볼트(30)가 체결되도록 체결공(12)에 삽입시키는 것에 의해 상기 범퍼(10)의 사이드부가 사이드프레임(20)에 결합되고 있다.The side portion of the conventional bumper is bent to one side on the top of the bumper 10 so that the upper surface of the flange 11 is in contact with the side frame 20, and the fastening bolt 30 is attached to the side frame 20. The side portion of the bumper 10 is coupled to the side frame 20 by inserting it into the fastening hole 12 so as to be fastened.

그러나 이러한 종래 자동차용 범퍼의 사이드부는 사이드프레임(20)의 저면에 접하며 체결볼트(30)에 의해 체결되는 플랜지(11)가 범퍼(10)의 상부 일측에 일측으로 절곡되는 것에 의해서만 형성됨으로서, 상기 플랜지(11)가 형성된 범퍼(10)의 사이드에 차량을 운행중 접촉사고등이 발생하여 외부의 충격이 가해지는 경우, 상기 범퍼(10)에 형성된 플랜지(11)가 충격에너지에 의해 쉽게 변형 및 파손되고, 상기 플랜지(11)가 변형 및 파손되는 것에 의해 사이드프레임(20)으로 부터 범퍼(10)의 사이드부가 분리되는 문제점이 있었다.However, the side portion of the bumper for a conventional vehicle is formed only by bending the flange 11 to one side on the upper side of the bumper 10 and being in contact with the bottom surface of the side frame 20 and fastened by the fastening bolt 30, the When an external impact is applied to the side of the bumper 10 on which the flange 11 is formed due to a contact accident while driving the vehicle, the flange 11 formed on the bumper 10 is easily deformed and damaged by impact energy. Then, there is a problem in that the side portion of the bumper 10 is separated from the side frame 20 by the deformation and damage of the flange 11.

본 발명의 목적은 상기 종래와 같은 문제점을 해결하기 위해, 플랜지와 범퍼의 내측면에 사이에 보강리브를 형성하여, 상기 플랜지에 외부의 충격이 가해지는 경우에도, 상기 플랜지가 변형 및 파손되는 것이 억제되도록 함으로서, 차실에 탑승한 승원의 안정성이 향상되도록 하는 자동차용 범퍼의 사이드부 보강구조를 제공하는 데 있다.An object of the present invention is to form a reinforcing rib between the flange and the inner surface of the bumper in order to solve the problem as in the prior art, even when an external impact is applied to the flange, the flange is deformed and damaged. It is intended to provide a reinforcement structure for a side portion of a bumper for a vehicle so that the stability of a crew on board a vehicle cabin is improved by suppressing it.

이하, 첨부된 도면에 의하여 본 발명의 그 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 자동차용 범퍼의 사이드부 보강구조도 도 2와 도 3 및 도 4에 도시하고 있는 바와 같이, 범퍼(10)의 내측 상부에 일측으로 절곡되어 사이드프레임(20)의 저면에 접하는 플랜지(11)가 형성되고, 상기 플랜지(11)에는 사이드프레임(20)에 체결되는 체결볼트(30)가 관통되게 삽입되도록 하는 체결공(12)이 관통되게 형성되는 것은 종래와 같다.As shown in Figs. 2 and 3 and 4, the reinforcing structure of the side part of the bumper for a vehicle of the present invention is bent to one side on the inner upper part of the bumper 10 and is in contact with the bottom surface of the side frame 20 ( 11) is formed, and a fastening hole 12 through which the fastening bolt 30 fastened to the side frame 20 is inserted through the flange 11 is formed to pass through, as in the related art.

단, 본 발명은 상기 플랜지(11)와 범퍼(10)의 내측면에 사이에 보강리브(13)가 형성됨을 그 기술적 구성상의 기본 특징으로 한다.However, the present invention is a basic feature of the technical configuration that the reinforcing rib 13 is formed between the flange 11 and the inner surface of the bumper 10.

따라서 이러한 본 발명은 차량을 운행중 차량의 측면으로 접촉사고등이 발생하여 범퍼(10)의 사이드부로 충격이 가해지는 경우에도, 사이드프레임(20)에 범퍼(10)의 사이드부가 연결되도록 하는 플랜지(11)가 보강리브(13)에 의해 변형 및 파손되는 것이 억제됨으로서, 충돌성능이 향상되어 차실에 탑승한 승원의 안정성이 향상됨은 물론, 상기 범퍼(10)의 사이드부가 사이드프레임(20)으로 부터 분리되는 것이 억제되어 차량의 외관미가 저감되는 것이 억제되도록 하는 효과가 있다.Therefore, in the present invention, even when a contact accident occurs to the side of the vehicle while driving the vehicle and an impact is applied to the side portion of the bumper 10, the flange for connecting the side portion of the bumper 10 to the side frame 20 ( 11) is suppressed from being deformed and damaged by the reinforcing ribs 13, the collision performance is improved and the stability of the crew in the car cabin is improved, as well as the side portion of the bumper 10 from the side frame 20. Separation is suppressed so that the appearance of the vehicle is suppressed from being reduced.

이상에서 살펴본 바와 같이 본 발명은차량의 정면과 후면에 설치되는 범퍼의 사이드부가 차량을 운행중 발생하는 접촉 사고등에 의해 사이드프레임으로부터 쉽게 분리되는 것이 억제되어, 차실에 탑승한 승원의 안정성이 향상되도록 하는 매우 유용한 발명이다.As described above, the present invention prevents the side parts of the bumpers installed at the front and rear of the vehicle from being easily separated from the side frame due to contact accidents occurring while driving the vehicle, thereby improving the stability of the crew in the vehicle cabin. It is a very useful invention.

이와 같이 구성되는 본 발명은, 플랜지(11)가 형성된 범퍼(10)의 사이드에 차량을 운행중 접촉사고등이 발생하여 외부의 충격이 가해지는 경우, 상기 범퍼(10)에서 1차적으로 충격에너지를 흡수 및 분산시킨 후 보강리브(13)로 전달하고, 상기 보강리브(13)에서 2차적으로 충격에너지를 흡수 및 분산시키며, 상기 보강리브(13)에서 2차적으로 흡수 및분산되고 남은 충격에너지는 플랜지(11)를 통해 사이드프레임(20)으로 폭넓게 분산되면서 충격에너지가 흡수된다.In the present invention configured as described above, when a contact accident occurs while driving a vehicle on the side of the bumper 10 on which the flange 11 is formed and an external shock is applied, the bumper 10 primarily generates impact energy. After being absorbed and dispersed, it is transferred to the reinforcing rib 13, and the impact energy is secondarily absorbed and dispersed in the reinforcing rib 13, and the remaining impact energy is secondarily absorbed and dispersed in the reinforcing rib 13 Impact energy is absorbed while being widely distributed to the side frame 20 through the flange 11.
