본 발명은 자동차용 범프스토퍼에 관한 것으로서, 더욱 더 상세하게는 바디와 섀시 사이에 설치되는 범프스토퍼의 몸체가 충분한 탄성력을 가지며 설치되도록 함과 동시에, 상기 바디에 범프스토퍼를 설치하는 것이 용이하게 이루어지도록 하는 자동차용 범프스토퍼에 관한 것이다.The present invention relates to a bump stopper for an automobile, and more particularly, the body of the bump stopper installed between the body and the chassis is provided with sufficient elastic force, and at the same time, it is easy to install the bump stopper on the body. It relates to a bump stopper for automobiles.

일반적으로 자동차용 서스펜션에는 차량이 범프나 리바운드시에도 섀시와 바디가 직접 충돌하지 않도록 하는 범프스토퍼가 설치되어 있다.Generally, suspensions for automobiles are provided with bump stoppers to prevent the chassis and the body from directly colliding even when the vehicle is bumped or rebounded.

여기에서 종래 자동차용 범프스토퍼는 도 1에 도시하고 있는 바와 같이, 자체 탄성력을 갖고있는 몸체(110)와, 상기 몸체(110)의 상부에 고정되게 장착되어있는 상부지지브라켓(120)으로 구성되어 있다.As shown in FIG. 1, the conventional bump bumper includes a body 110 having its own elastic force and an upper support bracket 120 fixedly mounted on an upper portion of the body 110. have.

이러한 종래 자동차용 범프스토퍼는 상부지지브라켓(120)의 상부면이 바디(200)의 저면에 접촉되도록 위치시킨 상태에서 볼트(600) 체결시켜 주는 것에 의해 상기 몸체(110)가 섀시(300)와 소정접촉상태가 유지되도록 설치된 상태를 유지하게 된다.In the conventional bump bumper for automobiles, the body 110 is connected to the chassis 300 by fastening the bolt 600 while the upper surface of the upper support bracket 120 is positioned to contact the bottom surface of the body 200. The installed state is maintained to maintain a predetermined contact state.

그러나 이러한 종래 자동차용 범프스토퍼는 상부지지브라켓(120)의 상부면이 바디(200)의 저면에 접촉하도록 설치하기 위해서는 몸체(110)의 길이방향으로 드라이버등과 같은 작업도구가 삽입될수 있는 공구홀(110)을 형성시켜야 함으로써, 상기 몸체(110)의 탄성력이 저하되는 문제점이 있었다.However, such a conventional bump bumper for a vehicle has a tool hole into which a work tool such as a driver can be inserted in the longitudinal direction of the body 110 in order to install the upper surface of the upper support bracket 120 in contact with the bottom surface of the body 200. By forming the 110, there was a problem that the elastic force of the body 110 is lowered.

또한, 상기 공구홀(110)이 형성되어 있는 몸체(110)가 일정수준 이상의 탄성력이 유지되도록 폭을 확대시키는 경우에는. 스프링(S)이 설치되어 있는 섀시(300)와 바디(200) 사이에 범프스토퍼(100)를 설치시, 상기 스프링(S)과 범프스토퍼(100)의 몸체(110) 사이에 갑섭이 발생하게 됨으로써, 상기 범프스토퍼(100)를 스프링(S)의 내부에 위치되도록 설치할 수 없게되는 문제점이 있었다.In addition, when the body 110 in which the tool hole 110 is formed is enlarged to maintain the elastic force of a predetermined level or more.

이러한 본 발명의 목적은, 자체 탄성력을 갖고있는 몸체(110)와, 상기 몸 체(110)의 상부에 고정되게 자력을 가지며 장착되는 상부지지브라켓(120)과 상기 상부지지브라켓(120)과 섀시(300)에 설치된 접촉상대물(310)과의 접촉상태를 감지하는 감지센서(130)와, 상기 감지센서(130)에 감지된 접촉상태에 따라 배터리(400)의 전원공급량을 제어하는 중앙처리장치(500)와, 상기 중앙처리장치(500)를 통해 공급되는 배터리의 전력 공급량에 따라 자력의 크기가 변화되는 전자석(140)으로 구성되는 것에 의해 달성된다.An object of the present invention, the body 110 has its own elastic force, and the upper support bracket 120 and the upper support bracket 120 and the chassis that is mounted to have a magnetic force to be fixed to the upper portion of the body 110 The central sensor for controlling the power supply of the battery 400 according to the detection sensor 130 for detecting a contact state with the contact object 310 installed in the 300 and the contact state detected by the detection sensor 130 It is achieved by the device 500 and the electromagnet 140, the magnitude of the magnetic force is changed in accordance with the power supply of the battery supplied through the central processing unit 500.

한편, 상기 상부지지브라켓(120)에는 결합돌기(121)가 상부로 돌출되어 형성되고, 상기 결합돌기(121)가 삽입되는 결합공(210)을 바디(200)에 형성시켜, 범프스토퍼(100)를 조립시, 작업자가 바디에 형성된 결합공(210)에 결합돌기(121)를 삽입시켜 주는 것에 의해 상기 범프스토퍼(100)가 바디(200)와 섀시(300)의 설치위치에 설치되어지게 된다. On the other hand, the upper support bracket 120 is formed by the coupling protrusion 121 protrudes upward, the coupling hole 210 is inserted into the coupling protrusion 121 is formed in the body 200, bump stopper 100 When assembling the operator, the bump stopper 100 is installed at the installation position of the body 200 and the chassis 300 by inserting the coupling protrusion 121 into the coupling hole 210 formed in the body. do.

이 구성에 의하면, 자체탄성력을 가지고 있는 범프스토퍼(100)의 몸체(110)에 자력을 가지고 있는 상부지지브라켓(120)을 결합시킨 상태에서, 상기 범프스토퍼(100)를 바디(200)의 저면에 접촉시켜 주는 것에 의해 상기 범프스토퍼(100)가 자력에 의해 바디(200)에 설치된 상태를 유지하게 됨으로써, 차량을 조립시 범프스토퍼(100)를 바디(200)와 섀시(300) 사이에 설치하는 것이 용이하게 이루어지게 된다.According to this configuration, in the state in which the upper support bracket 120 having magnetic force is coupled to the body 110 of the bump stopper 100 having its own elastic force, the bump stopper 100 is the bottom surface of the body 200. The bump stopper 100 is maintained in the state of being installed on the body 200 by magnetic force by contacting the bump stopper 100, so that the bump stopper 100 is installed between the body 200 and the chassis 300 when the vehicle is assembled. It is easy to do.

따라서, 자동차를 조립시 작업시간이 단축되어지게 되어 차량의 제작단가가 저감되어지게 된다.Therefore, the work time is shortened when assembling the vehicle, thereby reducing the manufacturing cost of the vehicle.

또한 차랑을 운행중 범핑이 발생하여 상부지지브라켓(120)과 섀시(300)에 설 치된 상대접촉물(310)과의 접촉상태가 좁아지는 경우에는 감지센서(130)에 감지된 접촉상태량에 따라 중앙처리장치(500)가 전자석으로 배터리(400)의 전원을 공급하여 자력이 증대되도록 하는 것에 의해 몸체(110)로 들어오는 힘에 의해 상부지지브라켓(120)이 바디(200)로부터 분리되지 않게 된다.In addition, when bumping occurs while driving the car, the contact state between the upper support bracket 120 and the relative contact 310 installed in the chassis 300 is narrowed, according to the amount of contact state detected by the sensor 130. The upper support bracket 120 is not separated from the body 200 by the force coming into the body 110 by supplying power of the battery 400 to the electromagnet so that the magnetic force is increased.

본 발명의 자동차용 범프스토퍼는 자체 탄성력을 갖고있는 범프스토퍼(100)의 몸체(110)의 상부에 자력을 갖는 상부지지브라켓(120)이 결합되고, 상기 상부지지브라켓(120)에는 섀시(300)에 설치된 접촉상대물(310)과의 접촉상태를 감지하는 감지센서(130)가 설치된다.Bump stopper for automobiles of the present invention is coupled to the upper support bracket 120 having a magnetic force on the upper portion of the body 110 of the bump stopper 100 has its own elastic force, the upper support bracket 120 to the chassis 300 A detection sensor 130 for detecting a contact state with the contact object 310 installed in the) is installed.

한편, 상기 범프스토퍼(100)가 설치되는 바디(200)의 상부에는 중앙처리장치(500)에 의해 배터리(400)의 전원 공급량이 제어되면서 자력이 변화되는 전자석(140)이 설치되고, 상기 중앙처리장치(500)는 감지센서(130)를 통해 감지되는 상부지지브라켓(120)과 섀시(300)에 설치된 상대접촉물(310)과의 접촉상태에 따라 전자석(140)에 공급되는 전원공급량을 제어하도록 한다On the other hand, the upper portion of the body 200 in which the bump stopper 100 is installed, the electromagnet 140 is installed, the magnetic force is changed while the power supply amount of the battery 400 is controlled by the central processing unit 500, the center The processing device 500 measures the power supply amount supplied to the electromagnet 140 according to the contact state between the upper support bracket 120 detected by the sensor 130 and the relative contact 310 installed in the chassis 300. To control

이와같이 구성되는 본 발명은, 자체탄성력을 가지고 있는 범프스토퍼(100)의 몸체(110)에 자력을 가지고 있는 상부지지브라켓(120)을 결합시키고, 상기 상부지지브라켓(120)의 상부에 돌출형성된 결합돌기(121)를 바디(200)에 형성된 결합공(210)에 삽입시켜 주게되면 상기 범프스토퍼(100)가 정확한 위치에 자력에 의해 설치된 상태를 유지하게 된다.The present invention configured as described above, coupled to the upper support bracket 120 having a magnetic force to the body 110 of the bump stopper 100 having its own elastic force, the coupling formed to protrude on the upper support bracket 120 When the protrusion 121 is inserted into the coupling hole 210 formed in the body 200, the bump stopper 100 maintains a state in which it is installed by a magnetic force.

한편, 상기와 같이 바디(200)와 섀시(300) 사이에 설치된 범프스토퍼(100)의 몸체(110)에 차량을 운행시 범핑이 발생하여 하중이 발생하면 도 5에 도시하고 있는 바와 같이, 거리센서(130)로부터 범프스토퍼(100)와 만나는 섀시 접촉상대물과의 거리를 d라고 할 때, d = L 에서 접촉이 시작하고, d = l 에서 풀범프(Full Bump) 라 하면 d=L이 되는 순간 코일에 전류를 흘려보내 전자석이 작동을 시작하게 하고 d = l이 되는 순간까지 흐르는 전류량을 증가시켜 d = l이 되는 순간 최대 전류가 흐르게 하고 다시 d > l이 되면 전류량을 점차 감소시켜 d > L 이되면 전류를 흘려보내지 않게된다. On the other hand, as shown in Figure 5 when bumping occurs when driving the vehicle to the body 110 of the bump stopper 100 installed between the body 200 and the chassis 300 as described above, the load, as shown in FIG. When d is the distance from the sensor 130 to the chassis contact object that meets the bump stopper 100, d starts contacting at d = L, and d = l when full bump at d = l. Current flows through the coil at the moment that the electromagnet starts to work and increases the current flowing until the moment d = l so that the maximum current flows at the time d = l and then decreases the current amount d d again. > L will not flow current.

이때, 상기 범프스토퍼(100)가 섀시(300)의 상대접촉물(310)과 접촉 시부터 전류를 세게 흘려주는 이유는 범프량이 증가하면 범프스토퍼(100)에 들어오는 하중이 점점 커지기 때문에 범프스토퍼(100)가 바디(200)로부터 이탈되는 것을 방지하기 위함이다.At this time, the reason why the bump stopper 100 flows a hard current from the contact with the relative contact 310 of the chassis 300 is because the load entering the bump stopper 100 increases as the amount of bump increases and thus the bump stopper ( This is to prevent the 100 from being separated from the body 200.

또한, 상기 범프스토퍼(100)가 섀시(300) 상대접촉물(310)과 접촉하지 않으면 범프스토퍼(100)로 들어오는 힘이 거의 없기 때문에 처음에 만들어준 상부지지브라켓(120)의 자력만으로도 충분히 조립된 상태를 유지하기 때문이다.In addition, if the bump stopper 100 does not come into contact with the relative contact 310 of the chassis 300, there is almost no force coming into the bump stopper 100, and thus the assembly of the upper support bracket 120 made by the magnetic force is sufficient. This is because it is kept intact.

따라서 이러한 본 발명은 자체탄성력을 가지고 있는 범프스토퍼(100)의 몸체(110)에 자력을 가지고 있는 상부지지브라켓(120)을 결합시킨 상태에서, 상기 범프스토퍼(100)를 바디(200)의 저면에 접촉시켜 주는 것에 의해 상기 범프스토퍼(100)가 자력에 의해 바디(200)에 설치된 상태를 유지하게 됨으로써, 차량을 조립시 범프스토퍼(100)를 바디(200)와 섀시(300) 사이에 설치하는 것이 용이하게 이루어지게 되고, 자동차를 조립시 작업시간이 단축되어지게 되며, 차량의 제작단가가 저감되어지도록 하는 효과가 있다.Therefore, the present invention is coupled to the upper support bracket 120 having a magnetic force to the body 110 of the bump stopper 100 having its own elastic force, the bump stopper 100 to the bottom surface of the body 200 The bump stopper 100 is maintained in the state of being installed on the body 200 by magnetic force by contacting the bump stopper 100, so that the bump stopper 100 is installed between the body 200 and the chassis 300 when the vehicle is assembled. It is easy to make, the working time is reduced when assembling the vehicle, there is an effect that the manufacturing cost of the vehicle is reduced.

또한 본 발명은 차랑이 운행중 범핑이 발생하여 상부지지브라켓(120)과 섀시(300)에 설치된 상대접촉물(310)과의 접촉상태가 좁아지는 경우에는 감지센서(130)에 감지된 접촉상태량에 따라 중앙처리장치(500)가 전자석으로 배터리(400)의 전원을 공급하여 자력이 증대되도록 하는 것에 의해 몸체(110)로 들어오는 힘에 의해 상부지지브라켓(120)이 바디(200)로부터 분리되지 않게되는 등의 효과가 있는 매우 유용한 발명이다.In addition, in the present invention, when bumping occurs while driving in a lane, the contact state between the upper support bracket 120 and the relative contact 310 installed in the chassis 300 is narrowed to the amount of contact state detected by the sensor 130. Accordingly, the central processing unit 500 supplies the power of the battery 400 to the electromagnet so that the magnetic force is increased so that the upper support bracket 120 is not separated from the body 200 by the force entering the body 110.
