Description
본 고안은 차량 후방장애물 감지시 자동으로 제동되게 하는 후진시 접촉사고 방지장치에 관한 것이다.The present invention relates to a device for preventing accidents during reverse driving to automatically brake when detecting an obstacle behind a vehicle.
종래에는 자동차 후퇴시에는 직접 눈으로 확인할 수 없는 자동차 후방의 사각을 보충할 목적으로 차량 후방에 모니터 카메라를 설치하거나 또는 감지센서를 부착하여 운전자에게 경고하도록 하는 고안이 제시된 바 있다.In the related art, in order to compensate for blind spots at the rear of the vehicle, which cannot be seen directly when the vehicle is retracted, a device for installing a monitor camera at the rear of the vehicle or attaching a sensor has been proposed to warn the driver.
그러나 이러한 근접워닝 경고장치는 경고음이나 또는 모니터를 통해 장애물을 감지한 후 운전자가 직접 브레이크를 조작하여야 되기 때문에 순발력이 부족할 경우 접촉사고를 방지하는데는 미흡한 실정이다.However, the proximity warning device is insufficient to prevent contact accidents when the wits are insufficient because the driver must operate the brakes directly after detecting an obstacle through a warning sound or a monitor.
본 고안은 이러한 점을 감안하여 안출된 것으로, 특히 후방장애물이 감지될 경우 자동으로 차량이 제동되게 하여 접촉사고를 원천적으로 방지할 수 있는 후진시 접촉사고 방지장치를 제공하는데 그 목적이 있다.The present invention has been devised in view of this point, and in particular, it is an object of the present invention to provide a contact accident prevention device in reverse when the vehicle is automatically braked when a rear obstacle is detected.
이러한 목적을 달성하기 위한 본 고안의 후진시 접촉사고 방지장치는 차량 리어범퍼 소정위치에 설치되어 후방 장애물을 감지하는 후방감지센서와, 상기 후방감지센서에 의해 장애물이 감지될 경우 전원이 통전되어 구동하는 구동모터와, 상기 구동모터와 축설되는 웜기어와, 상기 웜기어의 웜휠이 회전할 경우 브레이크페달을 연동시키는 체인으로 구성됨을 특징으로 한다.In order to achieve the above object, the device for preventing accidents during reversing is installed at a vehicle rear bumper at a predetermined position to detect a rear obstacle, and when the obstacle is detected by the rear sensor, the power is energized and driven. It characterized in that it comprises a drive motor, a worm gear that is built up with the drive motor, and a chain linking the brake pedal when the worm wheel of the worm gear rotates.
상기 브레이크페달과 브라켓트 사이에 체인을 감합한 상태로 탄성부재가 설치됨을 특징으로 한다.An elastic member is installed in a state in which a chain is fitted between the brake pedal and the bracket.
이러한 구성에 의하면, 본 고안은 센서에 의해 후방 장애물이 감지되면 구동모터에 전원이 인가되고 동시에 웜휠이 회전하면서 브레이크페달을 끌어당겨 자동으로 제동을 걸게 된다.According to this configuration, when the rear obstacle is detected by the sensor, the power is supplied to the driving motor, and at the same time, the worm wheel rotates and pulls the brake pedal to automatically apply braking.

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 통해 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안의 구성도 및 회로도로써, 도면중 부호 100은 브레이크페달이다. 본 고안은 도 2와 같이 차량 리어범퍼 소정위치에 설치되어 후방 장애물을 감지하는 후방감지센서(110)와, 상기 후방감지센서에 의해 장애물이 감지될 경우 전원이 통전되어 구동하는 구동모터(120)와, 상기 구동모터의 회전축과 축설된 웜(121) 및 이와 치합되는 웜휠(122)과, 상기 웜휠(122)의 회전시 브레이크페달(100)을 끌어당기는 체인(130)과, 상기 브레이크페달(100)과 브라켓트(140) 사이에 체인(130)이 삽입되게 설치되는 복원스프링(141)으로 구성되어 후방 장애물 감지시 자동으로 차량에 제동이 걸리도록 한다. 도면중 부호 SW1은 온/오프 모드스위치이고 L1은 경고등이다.1 is a configuration diagram and a circuit diagram of the present invention, in which 100 is a brake pedal. The present invention is installed in the vehicle rear bumper predetermined position as shown in Figure 2 and the rear detection sensor 110 for detecting a rear obstacle, the drive motor 120 is energized to drive when the obstacle is detected by the rear detection sensor 120 And, the worm 121 and the worm wheel 122 and the toothed shaft and the rotation axis of the drive motor, the chain 130, which pulls the brake pedal 100 during the rotation of the worm wheel 122, and the brake pedal ( It is composed of a restoring spring 141 is installed so that the chain 130 is inserted between the 100 and the bracket 140, so that the brake is automatically applied to the vehicle when the rear obstacle is detected. In the figure, SW1 is an on / off mode switch and L1 is a warning light.
이하, 상기한 실시예 구성에 따른 작용을 상세하게 설명하면, 본 고안은 차량이 후진하면서 장애물이 자동차 리어범퍼에 설치된 후방감지센서(110)에 의해 감지되면, 전원라인이 폐회로를 형성하면서 경고등(L1)을 점등시킴과 동시에 구동모터(120)에 전원이 인가되며, 동시에 회전축에 축설된 웜(121)이 회전하면서 웜휠(122)을 회전시키게 된다. 이와 같이 웜휠(122)이 회전하면 이와 일체로 형성된 체인(122)이 웜휠의 축에 권선되면서 브레이크페달(100)을 잡아당기게 되고 이로 인해 마스터실린더에 유압이 작용하여 제동이 걸리게 된다.Hereinafter, the operation according to the above embodiment configuration in detail, the present invention is when the vehicle is reversed, when the obstacle is detected by the rear detection sensor 110 installed in the car rear bumper, the power line forms a closed circuit warning light ( At the same time the L1) is turned on and the power is applied to the driving motor 120, and at the same time rotates the worm 121 is installed on the rotating shaft to rotate the worm wheel 122. As the worm wheel 122 rotates as described above, the chain 122 formed integrally with the worm wheel 122 is wound around the shaft of the worm wheel, thereby pulling the brake pedal 100. Accordingly, hydraulic pressure is applied to the master cylinder, thereby causing braking.
반대로, 차량이 전진하거나 또는 후방에 장애물이 제거되면 전원라인은 개회로를 형성하게 되고 이로 인해 경고등(L1)이 소등되면서 구동모터(120)에 인가되는 전원도 차단된다. 동시에 복원스프링(141)의 복원력에 의해 웜휠(122)에 권선된 체인(122)이 풀리게 되고 브레이크페달(100)이 원상태로 복귀하면서 마스터실린더에 가압된 유압이 감압되어 제동이 해제된다. 이러한 작용은 모드스위치(SW1)가 온 상태일 경우에만 가능하게 된다.On the contrary, when the vehicle moves forward or the obstacle is removed from the rear, the power line forms an open circuit, and thus the power applied to the driving motor 120 is cut off while the warning light L1 is turned off. At the same time, the chain 122 wound around the worm wheel 122 is released by the restoring force of the restoring spring 141, and the brake pedal 100 is restored to its original state, and the hydraulic pressure applied to the master cylinder is reduced to release the braking. This operation is possible only when the mode switch SW1 is on.
이상에서 설명한 바와 같이 본 고안은 후진시 후방감지센서에 의해 일정거리내에 장애물이 감지되면 자동으로 브레이크페달이 조작되게 하여 제동이 걸리도록 함으로써 접촉사고를 방지하게 된다.As described above, the present invention prevents contact accidents by automatically braking the brake pedal when the obstacle is detected within a certain distance by the rear sensor during retraction.
