즉, 상기 장애물감지센서(20)는 밀폐된 도어(1)가 개방될 때 도어개방감지센서(10)와 연동되어 작동되면서 실외측의 장애물을 감지하게 되는 것이다.That is, the obstacle detection sensor 20 is operated in conjunction with the door open detection sensor 10 when the closed door 1 is opened to detect the obstacle on the outdoor side.
또한, 상기 전방현가장치(40)와 후방현가장치(50)는 차량의 전후방에 각각 장착된 쇽업소버이며, 상기 현가장치작동수단(60)에 의해 발생된 압축공기는 쇽업소버의 공기실로 유입되게 된다.In addition, the front suspension device 40 and the rear suspension device 50 are shock absorbers mounted in front and rear of the vehicle, respectively, and the compressed air generated by the suspension device operation means 60 is introduced into the air chamber of the shock absorber. do.
그리고, 상기 현가장치작동수단(60)은, 상기 전자제어유니트(30)의 제어신호에 의해 온/오프되는 차고조정작동스위치(61)와, 이 차고조정작동스위치(61)에 의해 구동되면서 외기를 압축시키도록 된 공기압축기(62)와, 이 공기압축기(1)에서 발생한 압축공기의 압력을 제어하도록 된 압력조정밸브(63)와, 압축공기를 저장하는 공기탱크(64)와, 상기 공기압축기(62)와 공기탱크(64)사이에 설치되어 압축공기내의 수분을 제거하면서 압축공기가 상기 공기탱크(64)로 과공급되는 것을 방지하도록 된 에어드라이어(65)와, 하중의 변화에 따라 전방현가장치(40)와 후방현가장치(50)안의 공기압을 적절히 조정하도록 된 전방에어밸브(66) 및 후방에어밸브(67)로 구성되어 있다.The suspension operating means 60 is a garage adjustment operation switch 61 that is turned on / off by a control signal of the electronic control unit 30, and is driven by the garage adjustment operation switch 61 while the outside air is driven. An air compressor 62 for compressing the pressure, a pressure regulating valve 63 for controlling the pressure of the compressed air generated in the air compressor 1, an air tank 64 for storing the compressed air, and the air. An air dryer 65 installed between the compressor 62 and the air tank 64 to prevent the compressed air from being excessively supplied to the air tank 64 while removing moisture in the compressed air; It consists of the front air valve 66 and the rear air valve 67 which adjust the air pressure in the front suspension apparatus 40 and the rear suspension apparatus 50 suitably.
한편, 운전석에 위치된 계기판에는 경고등과 경고음발생수단이 장착되어 있으며, 이 경고등과 경고음발생수단은 상기 전자제어유니트(30)의 제어신호에 의해작동되도록 되어 있다.On the other hand, the instrument panel located in the driver's seat is equipped with a warning light and warning sound generating means, the warning light and warning sound generating means is to be operated by the control signal of the electronic control unit (30).
즉, 상기 전자제어유니트(30)에 의해 개방되는 도어(1)가 실외측의 장애물과 접촉된다고 판단하게 되면 상기 전자제어유니트(30)는 현가장치작동수단(60)을 구동하여 차고를 조정함과 동시에 계기판에 장착된 경고등과 경고음발생수단을 작동시켜 운전자 및 탑승자에게 주의를 환기시키게 된다.That is, when it is determined that the door 1 opened by the electronic control unit 30 is in contact with an obstacle on the outdoor side, the electronic control unit 30 drives the suspension operating means 60 to adjust the garage. At the same time, the warning lights and warning sound generating means mounted on the instrument panel are operated to draw attention to the driver and the occupant.
이하, 본 발명에 따른 차고조정장치의 작동과정에 대해 설명하기로 한다.Hereinafter, an operation process of the garage adjustment apparatus according to the present invention will be described.
먼저, 차량의 탑승자가 하차를 위해 인너핸들(1a)을 작동시키게 되면 도어개방감지센서(10)가 이를 감지하여 도어(1)의 개방상태를 전자제어유니트(30)로 전송하게 된다.First, when the occupant of the vehicle operates the inner handle 1a for getting off, the door open detection sensor 10 detects this and transmits the open state of the door 1 to the electronic control unit 30.
이와 동시에 상기 도어(1)에 장착된 장애물감지센서(20)는 실외측에 위치되고 개방되는 도어(1)의 회전반경내에 위치된 장애물을 감지하여 전자제어유니트(30)로 전송하게 된다.At the same time, the obstacle detecting sensor 20 mounted on the door 1 detects an obstacle located within a rotation radius of the door 1 located at the outdoor side and transmits the detected obstacle to the electronic control unit 30.
이에 따라, 상기 전자제어유니트(30)는 도어개방감지센서(10)에 의해 도어(1)의 개방상태를 판단하게 되고, 동시에 장애물감지센서(20)에 의해 개방되는 도어(1)의 최하단부가 인도 및 장애물등에 접촉되는지를 판단하게 된다.Accordingly, the electronic control unit 30 determines the open state of the door 1 by the door open sensor 10, and at the same time, the lowest end of the door 1 opened by the obstacle sensor 20. Judgment is made as to whether it is contacted with sidewalks or obstacles.
이때, 상기 전자제어유니트(30)에 의해 개방되는 도어(1)의 최하단부가 장애물과 접촉된다고 판단되면, 상기 전자제어유니트(30)는 차고조정작동스위치(61)를 온(on)시켜 공기압축기(62)를 구동시키게 되고, 이 공기압축기(62)의 구동으로 인해 발생된 압축공기는 에어드라이어(65)를 경유하여 공기탱크(64)에 저장되게 된다.At this time, if it is determined that the lowermost end of the door 1 opened by the electronic control unit 30 is in contact with the obstacle, the electronic control unit 30 turns on the garage adjustment operation switch 61 to turn on the air compressor. (62) is driven, and the compressed air generated by the driving of the air compressor (62) is stored in the air tank (64) via the air dryer (65).
그리고, 상기 공기탱크(64)에 보관된 압축공기는 상기 전자제어유니트(30)의 제어신호에 의해 선택적으로 온/오프되는 전방에어밸브(66) 및 후방에어밸브(67)를 경유하여 전방현가장치(40) 및 후방현가장치(50)로 공급되게 되며, 상기 전방현가장치(40) 및 후방현가장치(50)의 작동으로 인해 차고가 조정되어 개방되는 도어(1)가 실외측에 위치된 장애물과 접촉되는 것이 방지되게 된다.In addition, the compressed air stored in the air tank 64 has a front suspension via the front air valve 66 and the rear air valve 67 which are selectively turned on / off by the control signal of the electronic control unit 30. The door 40, which is supplied to the device 40 and the rear suspension device 50 and the garage is adjusted and opened due to the operation of the front suspension device 40 and the rear suspension device 50, is located at the outdoor side. Contact with the obstacle is prevented.
한편, 차고조정이 완료되고 탑승자가 하차하여 차량의 중량이 감소되게 되면, 상기 전방현가장치(40) 및 후방현가장치(50)로 공급된 압축공기는 전자제어유니트(30)의 제어신호에 의해 대기로 배출되게 되며, 이로 인해 차량의 차고는 정상상태로 복귀되게 된다.On the other hand, when the height adjustment is completed and the occupant gets off and the weight of the vehicle is reduced, the compressed air supplied to the front suspension unit 40 and the rear suspension unit 50 by the control signal of the electronic control unit 30 It is discharged to the atmosphere, which causes the garage of the vehicle to return to its normal state.
이와 같이, 도어(1)의 개방될 때 차량의 차고가 본 발명에 따른 차고조정장치에 의해 자동적으로 조정되게 됨으로써, 탑승자의 하차시 상기 도어(1)가 실외측에 위치된 장애물과 접촉되어 파손되는 것을 미리 방지할 수 있게 될 뿐만 아니라, 이로 인해 상기 도어(1)의 외관미가 나빠지게 되는 것도 예방할 수 있게 된다.As such, when the door 1 is opened, the height of the vehicle is automatically adjusted by the height adjusting device according to the present invention, so that the door 1 is in contact with an obstacle located at the outdoor side when the passenger gets off and is damaged. Not only can it be prevented in advance, but also prevents the appearance of the door 1 from deteriorating.
이상 설명한 바와 같이 본 발명에 의하면, 탑승자의 하차시 개방되는 도어가 실외측의 장애물과 접촉된다고 판단되면 현가장치작동수단에 의해 차고가 높게 조정되어 상기 도어와 장애물과의 접촉이 방지되게 됨으로써, 탑승자의 하차시 상기 도어(1)의 파손을 미리 예방할 수 있게 될 뿐만 아니라 이로 인해 상기 도어(1)의 외관미가 나빠지게 되는 것도 예방할 수 있게 되어 소비자의 선호도가 향상되면서 상품성이 증가되는 효과가 있게 된다.As described above, according to the present invention, when it is determined that the door that is opened when the occupant gets out of contact with an obstacle on the outdoor side, the height of the garage is adjusted by the suspension operating means so that contact between the door and the obstacle is prevented. In addition to being able to prevent the damage of the door (1) in advance when getting off, it is also possible to prevent the appearance of the door (1) is worsened, so that the consumer's preference is improved and the merchandise is increased. .
