차량의 차량도어(4)가 닫힌 상태에서 도어닫힘상태는 도어스위치(미도시됨)에 의하여 감지된다. 도어스위치는 도어의 열고 닫힘상태에 따라서 이에 상응하는 온/오프신호를 발생시키고, 발생된 온/오프신호는 차량의 ECU(미도시됨)에 의하여 감지되어서 필요한 동작을 수행한다. 상기 도어스위치와 ECU는 차량에서 널리 사용되고 있는 것이므로 상세한 설명은 생략한다.The door closed state is detected by a door switch (not shown) while the vehicle door 4 of the vehicle is closed. The door switch generates an on / off signal corresponding to the open / closed state of the door, and the generated on / off signal is detected by the ECU (not shown) of the vehicle to perform a necessary operation. Since the door switch and the ECU are widely used in a vehicle, detailed description thereof will be omitted.
도어닫힘상태로 감지되면 ECU에서는 유압펌프(20)의 피스톤을 상승시키도록 제어신호를 출력시킨다. 유압펌프(20)에서는 ECU로부터 제어신호가 입력되면 피스톤을 작동시켜 작동로드(22)를 상승시킨다. When the door is closed, the ECU outputs a control signal to raise the piston of the hydraulic pump 20. In the hydraulic pump 20, when the control signal is input from the ECU, the operating rod 22 is raised by operating the piston.
작동로드(22)의 상승에 의하여 도어지지판(10)의 타단부가 힌지결합된 일단부를 중심으로 상승하고, 상승된 도어지지판(10)은 차량도어(4)의 하부측에 밀착되면서 차량도어(4)가 진동에 의하여 상하이동되는 것을 방지하게 된다.The other end of the door support plate 10 is raised about the one end hinged by the lifting of the operation rod 22, and the raised door support plate 10 is in close contact with the lower side of the vehicle door 4, 4) is prevented from moving by vibration.
차량의 주행이 정지된 후에 차량도어(4)가 열리게 되면 도어스위치에서 도어의 열림상태를 감지한다. 감지신호는 ECU에 입력되며 ECU에서는 열림상태가 감지되면 유압펌프(20)에 제어신호를 출력하여 피스톤을 하강시킨다.When the vehicle door 4 is opened after driving of the vehicle is stopped, the door switch detects an open state of the door. The detection signal is input to the ECU and when the open state is detected in the ECU, the control signal is output to the hydraulic pump 20 to lower the piston.
피스톤의 하강에 따라서 작동로드(22)가 하강하게 되고, 이에 따라서 도어지지판(10)이 하강한다. 하강된 도어지지판(10)이 커버(30)의 커버돌출부(32) 사이에 안착하게 되면 하강이 정지된다. 따라서 차량의 차량도어(4)에 가해지던 압력이 해소되며 탑승자는 용이하게 차량도어(4)를 열고 나올 수 있다. 차량도어(4)가 닫히게 되면 도어지지판(10)은 상기한 것과 같이 상승하여 차량도어(4)를 지지한다.As the piston descends, the operation rod 22 descends, and accordingly the door support plate 10 descends. When the lowered door support plate 10 is seated between the cover protrusions 32 of the cover 30, the lowering is stopped. Therefore, the pressure applied to the vehicle door 4 of the vehicle is released and the occupant can easily open and exit the vehicle door 4. When the vehicle door 4 is closed, the door support plate 10 rises as described above to support the vehicle door 4.
본 발명의 장치는 차량도어(4)의 열림/닫힘상태에 따라서 작동되는 것이 설명되었지만, 차량의 주행중시에만 작동되도록 제어할 수 있다. 즉 ECU에서 차량의 주행상태, 또는 엔진작동상태를 확인한 경우에만 차량도어의 처짐방지장치를 선택적으로 작동시키는 것이 가능하다.Although the device of the present invention has been described to operate in accordance with the open / closed state of the vehicle door 4, it can be controlled to operate only during the running of the vehicle. That is, it is possible to selectively operate the deflection prevention device of the vehicle door only when the ECU confirms the driving state or the engine operation state of the vehicle.
이와 같은 본 발명에 의하면 도어가 닫히면 차량도어를 지지하도록 작동되고 도어가 열리면 지지해제상태로 복귀하여, 주행중인 차량도어에 반복적인 상하진동에 의한 처짐현상이 발생되는 것을 방지하는 효과가 있다.According to the present invention, when the door is closed, the door is operated to support the vehicle door, and when the door is opened, it returns to the released state, thereby preventing the drooping phenomenon caused by repeated vertical vibration in the driving vehicle door.
