[실시예]EXAMPLE

이하,본 발명의 바람직한 일 실시예를 첨부한 도면에 의하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.

제1도는본 발명에 따른 충돌 방지 브레이크장치를 도시한 도면으로, 부호(1)은 충돌 방지 브레이크장치를 지칭한다.1 is a diagram showing an anti-collision brake device according to the present invention, wherein reference numeral 1 denotes an anti-collision brake device.

상기한 충돌 방지 브레이크장치(1)는 자동차의 범퍼 등에 설치되어 앞차와 거리 및 제동등 밝기를 감지할 수 있는 센서(2)가 설치되어 있다.The anti-collision brake device 1 is installed on a bumper of a vehicle, and a sensor 2 capable of detecting the brightness of a front vehicle, a distance, and a braking lamp is installed.

상기한 센서(2)의 전기적인 신호를 감지한 전자제어장치(3)에 의해 컨트롤밸브(4)가 제어되며, 그리고 배터리(5) 전원이 전자제어장치(3)에 의해 에어펌프(6)에 인가되도록 하여 에어를 정정하도록 하고 있다.The control valve 4 is controlled by the electronic controller 3 which senses the electrical signal of the sensor 2, and the battery 5 is powered by the electronic controller 3 by the air pump 6. To correct the air.

상기한 에어펌프(6)에 의해 에어가 엑츄에이터(7)에 가압되면 액츄에이터(7)내의 피스톤(8)을 전진시키고, 이 피스톤과 일체로 된 푸쉬로드(9)는 전진하게 되어 있다.When air is pressurized by the air pump 6 by the above-mentioned air pump 6, the piston 8 in the actuator 7 is advanced, and the push rod 9 integrated with this piston is advanced.

상기한 액츄에이터(7)에 의해 전진하는 푸쉬로드(9)의 선단에 회전축(10)으로 푸쉬링크(11)가 연결되어 있다. 이 푸쉬링크(11)의 중간부위에는 힌지축(12)으로 고정되어 있어 푸쉬로드(9)의 전진시 푸쉬링크(11)가 회전하도록 되어 있다.The push link 11 is connected to the front end of the push rod 9 forward by the actuator 7 by the rotation shaft 10. The intermediate portion of the push link 11 is fixed to the hinge shaft 12 so that the push link 11 rotates when the push rod 9 moves forward.

상기한 푸쉬링크(11)의 일단에는 제1기어(13)가 연결되도록 하고 있으며, 이 제1기어(13)는 스플라인기어(14)가 형성된 브레이크축(15)에 설치되어 푸쉬링크(11)의 회동에 의해 제1기어(13)가 전진 이동하도록 되어 있다.The first gear 13 is connected to one end of the push link 11, and the first gear 13 is installed on the brake shaft 15 on which the spline gear 14 is formed, thereby pushing the push link 11. The first gear 13 moves forward by the rotation of.

상기한 제1기어(13)는 탄성부재(16)에 의하여 탄지된 상태에 있게 되는데, 푸쉬링크(11)가 작동하지 않을 때는 이 탄성부재(16)에 의해 탄지되어 브레이크축(15)의 스프라인기어(14)를 슬라이딩하도록 되어 있다.The first gear 13 is in a state of being held by the elastic member 16. When the push link 11 is not operated, the first gear 13 is supported by the elastic member 16 to be supported by the soup of the brake shaft 15. The line gear 14 is slid.

상기한 제1기어(13)가 푸쉬링크(11)의 회동에 의해 슬라이딩하여 전진함으로서 구동축(18)에 설치된 제2기어(19)와 치합하게 되어 있다.The first gear 13 is engaged with the second gear 19 provided on the drive shaft 18 by sliding forward by the rotation of the push link 11.

상기한 제2기어(19)에 제1기어(13)가 치합되면 전자제어장치(3)는 구동모타(20)를 작동시키게 되고, 이 구동모타(20)에 연결된 구동축(18)에 설치된 제2기어(19)가 회전하게 되어 있다.When the first gear 13 is engaged with the second gear 19, the electronic controller 3 operates the driving motor 20, and the first gear 13 is installed on the driving shaft 18 connected to the driving motor 20. The two gears 19 rotate.

상기한 제2기어(19)의 회전에 의해 치합된 제1기어(13)도 회전하게 되어 있기 때문에 브레이크축(15)도 같이 회전하게 되어 있다. 그리고 브레이크축(15)을 회전시키는 제2기어(19)는 계속 회전하여 브레이크축(15)에 설치된 브레이크페달(22)이 회동하여 제동이 이루어지도록 하고 있다.Since the first gear 13 engaged by the rotation of the second gear 19 is also rotated, the brake shaft 15 is also rotated together. The second gear 19 for rotating the brake shaft 15 continues to rotate so that the brake pedal 22 provided on the brake shaft 15 rotates to perform braking.

상기한 브레이크페달(22)의 회동에 의해 제동상태에 이르게 되면 구동모타(20)는 계속 회전하려고 하기 때문에 부하가 걸리게 되는데, 이때 구동모타(20)의 부하를 방지하기 위하여 구동축(21)에 슬립현상을 일으킬 수 있는 클러치(23)이 설치되어 있다.When the brake pedal 22 reaches the braking state due to the rotation of the brake pedal 22, the driving motor 20 is constantly trying to rotate, and a load is applied to the driving pedal 21. In this case, the driving shaft 21 is slipped to prevent the load of the driving motor 20. The clutch 23 which can cause a phenomenon is provided.

상기한 브레이크 페달(22)이 계속 회동함에 따라 구동모타(20)와, 컨트롤밸브(4)의 작동 정지와, 또 에어펌프(6)를 역회전시켜 엑츄에이터(7) 내의 에어가 배출됨에 따라 탄성부재(16)에 제1기어(13)가 제2기어(19)에서의 치합 해제와 더블어 제동도 해제되도록 브레이크페달(22)에 의해 온(ON)이 됨을 전자제어장치(3)에 전기적인 신호를 인가하는 브레이크 스위치(24)가 설치되어 있다.As the brake pedal 22 continues to rotate, the driving motor 20, the control valve 4 are stopped, and the air pump 6 is rotated in reverse to discharge the air in the actuator 7. The electronic device 3 is electrically connected to the member 16 so that the first gear 13 is turned ON by the brake pedal 22 so that the engagement and the double braking of the second gear 19 are also released. The brake switch 24 which applies a signal is provided.

제2도는 본 발명에 따른 에어펌프(6)에서 액츄에이터(8)로 공급될 때에는 콘트롤밸브(4)의 포트(A)에서 포트(B)를 통해 제1라인(25)을 통해 가압하고, 제동 해제시에는 전자제어장치(3)에 의해서 전원이 차단되면서 스프링(26)에 의해 포트변환이 이루어지면서 제2라인(27)을 통해 포트(C)와 포트(D)를 통해서 역회전하는 에어펌프(6)로 복귀하게 되어 있다.2 is pressurized through the first line 25 through the port B from the port A of the control valve 4 when supplied to the actuator 8 from the air pump 6 according to the present invention, and braking The air pump rotates backward through the port (C) and the port (D) through the second line (27) while the port is switched by the spring (26) while the power is cut off by the electronic controller (3). It is supposed to return to (6).

이와 갈이 이루어지는 본 발명의 작용은 주행 중에 예상치 못했던 앞차의 제동을 범퍼에 설치된 센서(2)가 거리 및 제동등 밝기 등을 감지하여 전자제어장치((3)에 전기적인 신호를 인가함으로서 전자제어장치(3)는 먼저 에어펌프(6)를 작동하여 엑츄에이터(7)로 하여금 제1기어(13)가 제2기어(19)와 치합하도록 한다.The operation of the present invention, which is made in this way, is applied to the electronic control device (3) by applying an electric signal to the electronic control device (3) by sensing the distance and the brightness of the braking light by the sensor (2) installed in the bumper for unexpected braking of the vehicle while driving. (3) first operates the air pump 6 to cause the actuator 7 to engage the first gear 13 with the second gear 19.

상기한 제1기어(13)가 제2기어(19)와 치합하면 전자제어장치(3)가 구동모타(20)를 회전시켜 제1기어(13)가 설치된 브레이크축(15)을 회전시키게 되면, 이 브레이크 축(15)에 설치된 브레이크페달(22)이 회동하여 제동이 이루어지면서 브레이크 스위치(24)도 온(ON)이 된다.When the first gear 13 meshes with the second gear 19, the electronic controller 3 rotates the driving motor 20 to rotate the brake shaft 15 provided with the first gear 13. When the brake pedal 22 provided on the brake shaft 15 is rotated and braking is performed, the brake switch 24 is also turned ON.

상기한 브레이크스위치(24)가 온(ON)이 됨에 따라 전자제어장치(3)는 브레이크의 제동상태를 해제시키기 위하여 제일 먼저 구동모타(20)를 정지시키고 다음은 에어펌프(6)와 엑츄에이터(7)를 연통시키고 있던 컨트롤밸브(4)를 후진시켜 정지시키고 이어서 에어펌프(6)를 역회전시키게 된다.As the brake switch 24 is turned on, the electronic controller 3 first stops the driving motor 20 in order to release the braking state of the brake, and then the air pump 6 and the actuator ( The control valve 4 which communicates 7) is reversed and stopped, and the air pump 6 is then reversed.

이에 따라 상기한 엑츄에이터(7) 내의 에어가 빠져 나오면서 푸시시로드(9)가 후진하게 되고, 이어 제1기어(13)가 탄성부재(16)의 탄지력에 의해 제2기어(19)에서 이탈되게 되어 브레이크의 제동은 운전자에 의해서 제동할 수 있게 되어 있다.Accordingly, the rod 9 is pushed backward while the air in the actuator 7 is released, and the first gear 13 is separated from the second gear 19 by the holding force of the elastic member 16. Therefore, the braking of the brake can be braked by the driver.

이러한 본 발명은 앞차의 급제동에 대해 뒤따르던 자동차는 안전하게 제동이 걸리게 됨으로 운전자가 당황하지 않고 후속조치를 취할 수 있는 경우가 생기며 이에 따라 앞차의 급제등 또는 운전자의 전방 주시 태만에 의해 발생할 수 있는 안전사고의 유발을 방지할 수 있는 효과가 있다.In the present invention, the vehicle following the sudden braking of the front vehicle is safely braked, so that the driver may take a follow-up action without being embarrassed, and thus the safety that may be caused by the emergency lighting of the front vehicle or the neglect of the driver ahead. There is an effect that can prevent the occurrence of an accident.
