Description

자동차의 보조범퍼장치{SUB-BUMPER OF A CAR}Auxiliary bumper device for vehicle {SUB-BUMPER OF A CAR}

본 고안은 자동차의 보조범퍼장치에 관한 것이다.The present invention relates to a secondary bumper device of a vehicle.

종래의 자동차마다 차체의 전후 양단부에 범퍼가 장착되어 있고 범퍼에 의하여 차체가 어떤 물체와 부디치면 범퍼가 충돌시의 충격을 완충할 수 있게 되어 있다.In conventional automobiles, bumpers are mounted on both front and rear ends of the vehicle body, and the bumper can cushion the impact when the vehicle collides with an object by the bumper.

자동차의 범퍼는 종류가 다양하며, 승용차의 경우에는 주로 범퍼를 구성하고 있는 고강도 합성수지의 재질적인 탄성에 의하여 충돌시의 충격을 완충하게 되어 있다. 그러나 기존 범퍼만으로는 범퍼가 감당할 수 있는 완충능력이 한계가 있고 또 범퍼의 완충기능은 높을 수록, 자동차의 안전성이 증대되기 때문에 범퍼의 기능을 개선하는데 제한이 있을 수 없다.There are various types of bumpers for cars, and in the case of passenger cars, the impact at the time of collision is buffered by the material elasticity of the high strength synthetic resin constituting the bumper. However, the existing bumper alone has a limited buffering capacity that the bumper can handle, and the higher the cushioning function of the bumper, the greater the safety of the car, so there is no limit in improving the function of the bumper.

또한 자동차의 충격을 완충하기 위한 범퍼의 구성은 다양하나 자동차 메이커에서 사양으로 정하여진 범퍼를 자동차에 장착하기 때문에 자동차에 장착된 범퍼에 의하여 자동차의 충격을 완충할 수 밖에 없었다.In addition, the configuration of the bumper to cushion the shock of the car is various, but because the bumper specified in the car manufacturer to install the bumper attached to the car was forced to buffer the shock of the car.

본 고안은 이러한 사정을 감안하여 본래 자동차에 장착된 주범퍼는 그대로 두고 여기에 보조범퍼를 복수개의 에어실린더에 의하여 전후로 움직일 수 있게 설치하여 에어실린더의 공기도관은 전자밸브를 통하여 압축공기탱크와 진공탱크측으로 연관하고 도관의 일단부측에 충격신호에 작동되는 배기전자밸브를 장착하였다.In view of such circumstances, the present invention leaves the main bumper originally mounted on the vehicle as it is, and the auxiliary bumper is installed to be moved back and forth by a plurality of air cylinders. The air conduits of the air cylinders are compressed air tanks and vacuum via solenoid valves. Exhaust solenoid valves connected to the tank side and actuated by shock signals on one end of the conduit were fitted.

평소, 자동차 주행시에는 보조범퍼가 주범퍼에 중접(重接)되어 있어 외견상 보조범퍼가 별로 눈에 띄이지 않는다. 그러나 소정의 속도(예컨데 50㎞/h)이상으로 주행중 급브레이크를 밟으면, 압축공기의 전자밸브가 열리면서 압축탱크로부터 고압공기가 공급되어 에어 실린더의 팽창으로 보조범퍼가 주펌퍼의 앞쪽으로 돌출하여 충돌에 예비한다. 또 밟었던 브레이크 패달을 떼면, 진공탱크의 전자밸브가 개방되면서 에어 실린더가 감압되어 돌출된 보조범퍼는 원위치로 복귀된다. 또 서행 중에는 브레이크 패달을 빈번하게 밟어도 보조범퍼는 움직이지 않는다. 소정 이상의 속도로 주행중 앞에 장해물이 나타나 급브레이크를 밟을 때만 보조 범퍼가 순간적으로 돌출되고 장해물과 부디치면, 충격신호에 의한 배기전자밸브의 개방으로 충돌에 따른 보조범퍼의 밀리는 충격에너지는 에어실린더의 고압공기의 배기작용으로 전환되어 보조범퍼는 서서히 후퇴되면서 충격을 흡수 완충하고 보조범퍼가 주범퍼에 중접된 후에는 주범퍼가 충격을 흡수 완충한다, 따라서 주범퍼와 보조펌퍼에 의하여 자동차의 충격에 대한 완충작용이 보다 증대되어 그만큼 자동차의 안전성을 높힐 수 있다.Normally, when driving a vehicle, the auxiliary bumper is overlapped with the main bumper, so the auxiliary bumper is not noticeable. However, if the sudden brake is pressed while driving at a predetermined speed (for example, 50 km / h), the solenoid valve of the compressed air is opened and the high pressure air is supplied from the compression tank so that the secondary bumper protrudes in front of the main pump due to the expansion of the air cylinder. Prepare to. When the brake pedal is released, the solenoid valve of the vacuum tank is opened and the air cylinder is depressurized, and the protruding auxiliary bumper returns to its original position. In addition, the auxiliary bumper does not move even if the brake pedal is frequently pressed during slow motion. When the obstacle appears in front of you while driving at a certain speed or more, the auxiliary bumper protrudes only momentarily when you step on the brake. The secondary bumper absorbs and cushions the shock by gradually retreating to the air, and after the secondary bumper is in contact with the main bumper, the main bumper absorbs and cushions the shock. Therefore, the main bumper and the auxiliary pump absorb the shock of the vehicle. The action can be further increased to increase the safety of the car.

또 보조범퍼는 인위적으로 작동시키는 것이 아니므로 운전자에게 전혀 별도의 부담이 없으며, 구조가 간단하여 보다 편리하게 설치 사용할 수 있게 안출한 것이다.In addition, the auxiliary bumper is not artificially operated, so there is no burden on the driver at all, and the structure is simple, and it is designed to be installed and used more conveniently.

자동차(1)의 전후 양단부에 주 범퍼(2)를 장착 한 것에 있어서, 주범퍼(2)의 앞쪽에 보조펌퍼(3)를 복수개의 에어실린더(4)와 피스톤(5)에 의하여 전후로 움직일 수 있게 장착하고, 에어실린더(4)에 관접된 공기 도관(6)에는, 압축탱크(도시되지 않음)의 전자밸브(v1)가 장착된 공급관(6')과, 진공탱크(도시되지 않음)의 전자밸브(v2)가 환류관(6') 및 충돌신호로 작동되는 전자배기밸브(v3)가 장착된 배기관(6'')을 각각 관접하여서 된 것이다.In the case in which the main bumpers 2 are mounted at both front and rear ends of the vehicle 1, the auxiliary pump 3 can be moved back and forth by the plurality of air cylinders 4 and the piston 5 in front of the main bumper 2. Air conduit 6, which is mounted in the air cylinder 4, is provided with a solenoid valve v 1 of a compression tank (not shown) and a vacuum tank (not shown). The solenoid valve v 2 of the valves is made by contacting the exhaust pipe 6 'and the exhaust pipe 6''equipped with the solenoid exhaust valve v 3 operated by the collision signal.

본 고안의 실시에 있어서 에어실린더의 장착 수단으로서 실린더(4)는 주범퍼의 내면에 보강철판(2')을 이용하여 장착하고 동 실린더(4)에 삽입된 피스톤(5)은 보조범퍼(3)의 내면에 보강철판(3')을 이용하여 장착해도 된다. 또 도3에 표시된 바와 같이 실린더와 피스톤 사이의 공간부에 탄성질의 주름관으로 된 신축성 에어백(5a)을 내장할 수도 있다.In the implementation of the present invention, as a mounting means of the air cylinder, the cylinder 4 is mounted on the inner surface of the main bumper by using a reinforcing steel plate 2 ', and the piston 5 inserted into the cylinder 4 is a secondary bumper (3). May be mounted on the inner surface of the panel using a reinforcing steel plate 3 '. As shown in Fig. 3, an elastic airbag 5a made of an elastic corrugated pipe may be incorporated in the space between the cylinder and the piston.

에어백(5a)을 내장한 때에는 에어백(5a)의 일단부에 공기도관(6)을 관접하여 압축공기를 주입 팽창하거나 흡기 수축할 수 있게 하고 에어백(5a)의 수축시에는 보조범퍼(3)가 주범퍼측으로 복귀할 수 있게 에어백(5a)의 타단부를 보조펌버 (3)에 연결한다.When the air bag 5a is incorporated, the air conduit 6 is connected to one end of the air bag 5a so that the compressed air can be injected, expanded or inflated and contracted. When the air bag 5a is contracted, the auxiliary bumper 3 The other end of the airbag (5a) is connected to the auxiliary pump (3) so as to return to the main bumper side.

도1, 도2는 자동차의 앞쪽에 설치된 보조범퍼를 표시하고 있으나 도3 및 도4에 표시된 보조범퍼의 구성은 자동차의 전후 양단부에 장착된 주 펌퍼에 동일하게 적용되며, 편의상 한쪽의 보조범퍼에 대하여만 설명한다.1 and 2 show an auxiliary bumper installed in the front of the vehicle, but the configuration of the auxiliary bumper shown in FIGS. 3 and 4 is equally applied to the main pumps mounted at both front and rear ends of the vehicle, and for convenience, the auxiliary bumper Explain only.

도면중 미설명 부호 7은 단자(a)(b)(c)를 통하여 유입되는 신호에 따라 각 전자 밸브를 제어하는 전자 제어기이다.In the figure, reference numeral 7 denotes an electronic controller that controls each solenoid valve in accordance with a signal flowing through the terminals (a) (b) (c).

이와 같이 된 본 고안은 도1 및 도3에 표시된 바와 같이, 에어 실린더(4)와 피스톤(5)은 수축상태이며 보조펌버(3)는 주범퍼(2)에 중접되어 있다.1 and 3, the air cylinder 4 and the piston 5 are in a contracted state, and the auxiliary pump 3 is in contact with the main bumper 2. As shown in FIGS.

자동차의 주행속도 신호와 브레이크 신호는 각각 단자(a)(b)를 통하여 전자제어기(7)로 유입된다. 그러나 소정의 속도 이하의 주행에서는 반복적으로 브레이크를 밟어도 전자제어기(7)는 작동신호가 송출되지 않으므로 각 전자밸브(v1)(v2)는 작동하지 않는다. 따라서 보조범퍼(3)는 주범퍼(2)에 중접된 채 운행된다.The traveling speed signal and the brake signal of the vehicle flow into the electronic controller 7 through terminals a and b, respectively. However, even when the brake is repeatedly applied at a predetermined speed or less, the electronic controller 7 does not transmit an operation signal, so that the respective solenoid valves v 1 and v 2 do not operate. Therefore, the auxiliary bumper 3 is operated while being in the indirect contact with the main bumper (2).

그러나 소정의 속도(예컨데 50km/h) 이상로 주행중에 급브레이크를 밟을 때는 전자제어기(7)로 부터 압축공기 탱크의 전자밸브(v1)에 동작신호가 송출되어 동전자밸브(v1)가 개방되면서 압축탱크(도시되지 않음)에서 압축공기가 공급관(6') 및 도관(6)을 통하여 각 실린더(4)에 공급팽창되어서, 도2 및 도3의 가상선으로 표시된 바와 같이 보조범퍼(3)는 주범퍼(2)의 앞쪽으로 돌출되고 돌출된 후에는 감지센서(도시되지 않음)에 의하여 압축공기탱크의 전자밸브(v1)는 닫히어 그 이상의 공기압력은 부가되지 않는다.However, when the brake is pressed while driving at a predetermined speed (for example, 50 km / h) or more, an operation signal is sent from the electronic controller 7 to the solenoid valve v 1 of the compressed air tank so that the coin valve v 1 is closed. As it is opened, compressed air is expanded in each of the cylinders 4 through the supply pipe 6 'and the conduit 6 in a compression tank (not shown), so that the auxiliary bumper (as indicated by the imaginary line in Figs. 3) is protruded to the front of the main bumper (2), and after being protruded, the solenoid valve v 1 of the compressed air tank is closed by a sensor (not shown) so that no further air pressure is applied.

밟은 브레이크를 떼면 정해놓은 지연시간(예컨데 약5초)후에 전자 제어기(7)로부터 이번에는 진공탠크의 전자밸브(v2)에 동작신호가 송출되어 동 전자밸브가 개방되면서 실린더내(4)의 공기를 환류관(6')을 통하여 흡입 감압시킨다. 따라서 도1 및 도3의 실선으로 표시된 바와 같이 보조범퍼(3)는 본래의 위치로 복귀하여 주범퍼(2)에 중접된다.After the brake is released, the operation signal is sent from the electronic controller 7 to the solenoid valve v 2 of the vacuum tank after the predetermined delay time (for example, about 5 seconds), and the solenoid valve is opened to open the inside of the cylinder 4. The air is suctioned and decompressed through the reflux tube 6 '. Thus, as indicated by the solid lines in Figs. 1 and 3, the auxiliary bumper 3 returns to its original position and is superimposed on the main bumper 2.

또 도2 및 도4에 표시된 바와 같이, 소정의 속도 이상으로 주행중 전방에 장해물이 나타나, 급브레이크를 밟으면, 상기한 바와 같이 보조범퍼(3)는 주범퍼(2)의 앞쪽으로 돌출되며 이상태에서 물체에 보조범퍼(3)가 부디치면, 부디치는 충격신호가 단자(c)로 유입되어 전자제어기(7)로 부터 전자 배기밸브(v3)측으로 동작신호가 송출되어 배기밸브(v3)가 개방된다.In addition, as shown in Figs. 2 and 4, obstacles appear in front of the vehicle while driving at a predetermined speed or more, and when the brake is pressed down, the auxiliary bumper 3 protrudes in front of the main bumper 2 as described above. When the auxiliary bumper 3 touches the object, the impact signal flows into the terminal c, and an operation signal is sent from the electronic controller 7 to the electromagnetic exhaust valve v 3 , whereby the exhaust valve v 3 is opened. Open.

따라서 보조범퍼(3)에 가해진 충격에너지는 보조범퍼(3)가 후퇴되는 동작에따라 실린더(5), 또는 에어백(5a)에 충전된 압축공기를 배기밸브(v3)를 통하여 배기관(6'')의 외부로 배출되는 작용으로 전환되어 보조범퍼(3)는 서서히 후퇴하면서 충격을 흡수한다. 보조범퍼(3)가 주범퍼(2)에 중접된 후에는 감지센서(도시되지 않음)에 의하여 전자배기밸브(v3)는 닫히고 중접된 후부터는 남어지 충격은 주범퍼(2)가 담당하여 완충작용을 하는 것이다.Therefore, the impact energy applied to the auxiliary bumper 3 is reduced by the exhaust pipe 6 'through the exhaust valve v 3 in the compressed air charged in the cylinder 5 or the air bag 5a as the auxiliary bumper 3 is retracted. The secondary bumper (3) is retracted to absorb the impact while being retracted to the action of discharged to the outside of '). After the auxiliary bumper 3 is in contact with the main bumper 2, the solenoid exhaust valve v 3 is closed by a sensor (not shown), and after the indirect contact, the remaining shock is acted on by the main bumper 2 to cushion the action. To do.

본 고안은 자동차의 주범퍼에 보조범퍼를 복수개의 에어실린더에 의하여 신축동작되게 장착하여 소정 이상의 주행속도에서 급브레이크를 밟을 때만 압축공기탱크의 전자밸브의 개방으로 압축공기가 공급되어 보조범퍼가 주범퍼 앞으로 돌출되고 브레이크 패달을 떼면 보조범퍼가 진공탱크의 전자밸브의 개방으로 복귀되게 구성하였기 때문에, 서행시에는 반복적으로 브레이크로 밟어도 보조범퍼는 동작하지 않어 그만큼 보조범퍼의 동작기구에 물리적인 무리가 적고 외견상 기존 범퍼와 차이가 없이 보인다.According to the present invention, the auxiliary bumper is elastically operated by a plurality of air cylinders to the main bumper of the vehicle so that the compressed air is supplied by opening the solenoid valve of the compressed air tank only when the rapid brake is applied at a predetermined or higher traveling speed. Since the auxiliary bumper is configured to return to the opening of the solenoid valve of the vacuum tank when the bumper protrudes in front of the bumper and is released, the auxiliary bumper does not operate even if the user presses the brake repeatedly in a slow motion. It is small and seemingly no difference from the existing bumper.

또 보조펌퍼가 돌출한 상태에서 혹 물체와 충돌하면 보조범퍼의 충격 에너지가 실린더의 압축공기의 배기작용으로 전환되므로 보조범퍼와 주범퍼 사이의 간격이 크기 않어도 배기조건의 조절에 따라 배기저항을 크게 할 수 있어 1차적인 완충작용을 높힐 수 있다.In addition, if the bumper collides with an object while the auxiliary pump is protruding, the impact energy of the auxiliary bumper is converted into the exhaust action of the compressed air of the cylinder. Therefore, even if the distance between the auxiliary bumper and the main bumper is not large, the exhaust resistance is adjusted according to the exhaust condition. It can increase the primary buffering effect.

또 보조범퍼에 의하여 1차적인 완충작용을 담당한 후에 남어지 충격에너지를 주범퍼가 담당하게 되므로 그만큼 자동차의 범퍼의 완충능력이 증대되어 자동차의 안전성이 높게 된다.In addition, since the primary bumper is responsible for the remaining impact energy after the primary shock absorbing action by the auxiliary bumper, the shock absorbing capacity of the bumper of the car increases, thereby increasing the safety of the car.

또 인위적으로 보조범퍼를 작동하는 것이 아니므로 운전자에게 별도의 부담을 주는 일이 없이 안전하게 운전할 수 있다.In addition, since the auxiliary bumper is not operated artificially, the driver can safely drive without burdening the driver.

보조범퍼는 구조가 간단하고 주범퍼에 간편하게 설치할 수 있으므로 기존의 자동차의 사양을 그대로 두고도 자동차 메이커에서 처음부터 보조범퍼를 주범퍼에장착할 수 도 있고 출고된 차량에 옵션에 따라 보조범퍼를 장착할 수 도 있다.Since the auxiliary bumper is simple in structure and can be easily installed in the main bumper, the car maker can mount the auxiliary bumper on the main bumper from the beginning even without the specification of the existing car. You may.

또 종래 주범퍼에만 자동차의 완충을 의존하던 것에 비하여 범퍼의 완충능력 보조범퍼에 의하여 증대되므로 충격으로 부터 차량과 운전자를 안전하게 보호할 수 있는 여러가지 효과가 있다.In addition, compared to the conventional bumper only relying on the cushioning of the car bumper bumper capacity is increased by the auxiliary bumper has a number of effects that can safely protect the vehicle and the driver from impact.
