Description

차량용 오버슬램 범퍼Car Overslam Bumper

본 고안은 자동차의 오버 슬램범퍼에 관한 것으로서, 보다 상세하게는 오버 슬램범퍼의 형상을 보완하여 완충력을 향상시켜, 진동 및 소음을 방지할 수 있는 차량용 오버 슬램범퍼에 관한 것이다.The present invention relates to an over slam bumper of an automobile, and more particularly, to an over slam bumper for a vehicle that can prevent vibration and noise by improving the buffering force by supplementing the shape of the over slam bumper.

일반적으로 자동차의 개폐가 가능한 곳 즉, 도어나 후드 또는, 트렁크 리드와 같은 개폐부재가 접촉하는 차체에는 완충부재로 성형된 오버 슬램범퍼가 설치되어 있다.In general, an over slam bumper formed of a shock absorbing member is installed in a vehicle body that can be opened and closed, that is, a door or hood, or a vehicle body in which an opening member such as a trunk lid contacts.

상기한 오버 슬램범퍼는 개폐부재가 닫힐 때, 그 충격력이 차체에 전달되는 것을 차단하고 또한, 상기 개폐부재의 변형을 방지하기 위해 완충력이 우수한 탄성체로 이루어진다.The over slam bumper is made of an elastic body excellent in cushioning force to block the transmission of the impact force to the vehicle body when the opening and closing member is closed, and to prevent deformation of the opening and closing member.

종래의 오버 슬램범퍼는 첨부된 도면 도 3에 도시된 바와 같이, 외주면으로 일정한 깊이와 홈을 형성하여 차체패널(100)에 결합되는 고정부(200)와, 상기한 고정부(200)의 일측으로 길이방향으로 성형되며, 개폐부재(미도시)와 접촉하는 마찰면(350)을 갖는 몸체부(300)로 이루어진다.Conventional over slam bumper is a fixed portion 200 is coupled to the vehicle body panel 100 by forming a predetermined depth and groove to the outer circumferential surface as shown in the accompanying drawings, one side of the fixing portion 200 It is formed in the longitudinal direction, and consists of a body portion 300 having a friction surface 350 in contact with the opening and closing member (not shown).

그러나, 상기한 오버 슬램범퍼는 개폐부재의 충격력을 자체 탄성력만으로 흡수하게 되는데, 장기간에 걸쳐 사용할 경우 파손 및 변형을 일으켜 완충성능이 저하되고, 수명 단축의 문제점이 있다.However, the over slam bumper is to absorb the impact force of the opening and closing member only by its own elastic force, when used over a long period of time, causing damage and deformation, the buffering performance is lowered, there is a problem of shortening the life.

또한, 상기한 오버 슬램범퍼는 개폐부재와의 접촉시 발생하는 충격력을 효과적으로 흡수하지 못하고 차체에 전가하게 된다.In addition, the over slam bumper does not effectively absorb the impact force generated when the contact with the opening and closing member is transferred to the vehicle body.

따라서, 상기한 차체와 개폐부재의 충격력이 커지게 되고, 이로 인해 페이트 벗겨짐이나, 개폐부재의 국부적인 변형을 초래하는 문제점이 있다.Therefore, the impact force between the vehicle body and the opening / closing member is increased, resulting in a peeling of the paint or a local deformation of the opening / closing member.

본 고안의 목적은 자동차의 개폐부재를 닫을 때, 발생하는 충격력에 충분하게 대응하는 반발력을 가질 수 있는 오버 슬램범퍼를 제공하는데 있다.An object of the present invention is to provide an over slam bumper that can have a repulsive force that sufficiently corresponds to the impact force generated when closing the opening and closing member of the vehicle.

상기한 바와 같은, 목적을 달성하기 위하여, 본 고안은 외주면으로 차체패널에 결합하기 위해 홈을 형성한 고정부와, 상기한 고정부의 일측에 길이방향으로 제공되며 개폐부재와 접촉하는 마찰면을 형성한 몸체부를 포함하고, 상기한 몸체부는 탄성부재를 내장할 수 있도록 한 차량용 오버 슬램범퍼를 제공한다.As described above, in order to achieve the object, the present invention provides a fixing portion formed with a groove for coupling to the vehicle body panel as an outer circumferential surface, and a friction surface provided in one side of the fixing portion in the longitudinal direction and in contact with the opening and closing member It includes a formed body portion, the body portion provides a vehicle over slam bumper to be able to embed the elastic member.

이와 같이, 이루어지는 오버 슬램범퍼는 충돌력에 대한 반발력을 향상시키고, 충격력을 분산 흡수할 수 있다.Thus, the over slam bumper made can improve the repulsive force with respect to a collision force, and can absorb and absorb an impact force.

이하 본 고안의 바람직한 실시예를 첨부한 도면을 참조하여 더욱 상게하게 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described more encouragingly.

도 1은 본 고안의 실시예에 따른 차량용 오버 슬램범퍼를 나타낸 단면도로서, 부호 1을 오버 슬램범퍼라 지칭한다.1 is a cross-sectional view showing a vehicle over slam bumper according to an embodiment of the present invention, the reference numeral 1 refers to an over slam bumper.

자동차의 개폐가 가능한 곳 즉, 도어나 후드 또는 트렁크 리드와 같은 개폐부재(2)와 접촉하는 차체에는 충격력을 흡수하기 위해 완충부재로 성형된 오버 슬램범퍼(1)가 제공된다.Where the vehicle can be opened and closed, that is, the vehicle body in contact with the opening and closing member 2 such as a door, hood or trunk lid is provided with an over slam bumper 1 formed of a shock absorbing member to absorb impact force.

상기한 오버 슬램범퍼(1)는 외주면으로 일정한 깊이와 홈을 형성하여 차체패널(3)에 결합되는 고정부(10)와, 상기한 고정부(10)의 일측에 설치되는 완충력이 우수한 탄성부재(30)와, 상기한 탄성부재(30)를 내부에 장착할 수 있는 길이방향의 중공부(25)를 형성하고, 그 일단은 고정부(10)의 상단에 결합되는 몸체부(20)로 이루어진다.The over slam bumper 1 has a fixed portion 10 coupled to the vehicle body panel 3 by forming a constant depth and a groove on an outer circumferential surface thereof, and an elastic member having excellent buffering force installed on one side of the fixed portion 10. 30 and the hollow portion 25 is formed in the longitudinal direction in which the elastic member 30 can be mounted therein, and one end thereof is coupled to the body portion 20 coupled to the upper end of the fixing portion 10. Is done.

상기한 몸체부(20)는 그 상측으로 개폐부재(2)와 접촉을 갖는 마찰면(21)이 제공되며, 상기 마찰면(21)은 내부에 형성된 중공부(25)와 연결되는 통기구(22)가 형성된다.The body portion 20 is provided with a friction surface 21 having a contact with the opening and closing member 2 to the upper side, the friction surface 21 is a vent 22 connected to the hollow portion 25 formed therein ) Is formed.

또한, 상기한 몸체부(20)는 바깥쪽으로 찌그러지도록 상기 몸체부(20)의 하측 외주면에 홈(23)을 형성한다.In addition, the body portion 20 forms a groove 23 on the lower outer circumferential surface of the body portion 20 to be distorted outward.

상기한 탄성부재(30)는 탄성력과 복원력이 우수한 코일스프링(30)이 사용될 수 있다.The elastic member 30 may be a coil spring 30 having excellent elastic force and restoring force.

이와 같이, 이루어지는 차량용 오버 슬램범퍼(1)는, 도어나 후드와 같은 개폐부재(2)가 닫힐 때 발생하는 충격력을 탄성부재(30)가 제공된 몸체부(20)에서 흡수하게 된다.In this way, the over-slam bumper 1 for a vehicle absorbs the impact force generated when the opening / closing member 2 such as a door or a hood is closed by the body portion 20 provided with the elastic member 30.

첨부된 도면 도 2는 본 고안에 따른 실시예를 나타낸 것으로서, 오버 슬램범퍼(1)의 마찰면(21)에 개폐부재(2)가 접촉된 상태를 나타냈다.2 is a view illustrating an embodiment according to the present invention, and a state in which the opening and closing member 2 is in contact with the friction surface 21 of the over slam bumper 1.

일반적으로, 개폐부재(2)는 오버 슬램범퍼(1)의 마찰면(21)에 수직방향으로 충돌력을 가하며, 상기한 오버 슬램범퍼(1)는 하방향으로 수축하게 된다.In general, the opening and closing member 2 exerts a collision force in the vertical direction on the friction surface 21 of the over slam bumper 1, the over slam bumper 1 is contracted downward.

특히, 오버 슬램범퍼(1)의 몸체부(20) 하측에 형성된 홈(23)은 몸체부(20)를 외측으로 변형되도록 유도한다.In particular, the groove 23 formed below the body portion 20 of the over slam bumper 1 induces the body portion 20 to be deformed outward.

상기한 몸체부(20)의 내부에는 탄성부재(30)가 설치되며, 이 탄성부재(30)는 충격력을 탄성에너지로 바꾸어 충격을 흡수한다.An elastic member 30 is installed inside the body 20, and the elastic member 30 absorbs shock by changing the impact force into elastic energy.

충격력이 최초로 작용하는 순간에, 상기한 마찰면(21)에 형성된 통기구(22)는 개폐부재(2)와 밀착하게 되어, 탄성부재(30)가 설치된 중공부(25)의 공기가 외부로 새어나가는 것을 방지하게 되어 몸체부(20)의 중공부(25)는 에어댐퍼 작용을 하게 된다.At the moment when the impact force acts for the first time, the air vent 22 formed in the friction surface 21 is in close contact with the opening and closing member 2, and the air of the hollow portion 25 provided with the elastic member 30 leaks to the outside. The hollow portion 25 of the body portion 20 is prevented from going out to act as an air damper.

충격력에 따른 몸체부(20)의 변형량이 증가하게 되면 개폐부재(2)와 밀착하는 마찰면(21)도 변형을 일으키게 되고 중공부(25)의 공기는 통기구(22)를 통해 배출된다.When the deformation amount of the body portion 20 according to the impact force increases, the friction surface 21 in close contact with the opening and closing member 2 also causes deformation, and the air of the hollow portion 25 is discharged through the vent 22.

따라서, 상기한 중공부(25)가 보유한 충격력에 따른 변형에너지를 개폐부재(2)쪽으로 되돌릴 수 있게 되며, 나머지 잔류 충격력은 탄성부재(30)가 대응하게 되어, 충격력을 분산할 수 있다.Therefore, the deformation energy according to the impact force retained by the hollow part 25 can be returned to the opening / closing member 2, and the remaining residual impact force corresponds to the elastic member 30, thereby dispersing the impact force.

상기한 오버 슬램범퍼는 탄성부재를 내장하므로 충격력에 대한 반발력을 높일 수 있으며, 개폐부재와 충돌시 그 충돌력을 분산 흡수할 수 있어 페인트 벗겨짐 및 개폐부재의 국부적인 변형을 방지할 수 있다.Since the over slam bumper has a built-in elastic member, it can increase the repulsive force against impact force, and can absorb and disperse the impact force when colliding with the open / close member, thereby preventing paint peeling and local deformation of the open / close member.
