Abstract

본 발명은 자동차의 후진시 후방의 장애물에 대한 경보 및 후방의 장애물을 자동으로 감지하여 차를 정지시키기 위한 브레이크장치에 관한 것이다.The present invention relates to a brake for stopping an automobile by automatically detecting an obstacle for an obstacle behind the vehicle and automatically detecting an obstacle behind the vehicle.

종래와 같이 송신되는 초음파와 수신되는 초음파와의 사이의 타이밍값(T)을 계산하여, 이를 경보에 필요한 기준시간(T0)과 비교함으로써 상기 타이밍값(T)이 경보용 기준시간(T0)보다 같거나 작으면 경보음을 발신하고, 이상의 종래의 방식에 부가하여 본 발명에서는 상기 타이밍값(T)을 충돌이 예상되는 기준시간(T1)과 비교하여 상기 타이밍값(T)이 충돌방지용 기준시간(T1)보다 같거나 작으면 자동으로 자동차를 정지시키기 위한 장치를 제공하는 데 그 목적이 있다. 따라서 후방 장애물이 있다는 경보음을 발하게 되는 기능과, 모터를 구동시켜 상기 모터의 축기어(15)를 회전시키고 이는 다시 레버(11)와 핀결합이 되어 있는 호형 레크(13)를 회전시키게 됨으로써 핸드브레이크를 작동시키게 되어 자동차를 정지시켜, 간단한 구성으로서 후진시 자동차의 충돌로 인한 손상을 방지함과 동시에 후방의 인마를 보호하게 되며 다른 자동차나 건물의 손상도 방지하게 되는 효과를 갖는다.By calculating the timing value T between the transmitted ultrasound and the received ultrasound as in the prior art, and comparing it with the reference time (T 0 ) required for the alarm, the timing value (T) is the alarm reference time (T 0). If it is less than or equal to), an alarm is sounded, and in addition to the conventional method described above, in the present invention, the timing value T collides with the timing value T compared with the reference time T 1 at which the collision is expected. It is an object of the present invention to provide a device for automatically stopping a vehicle when it is less than or equal to the reference time T 1 for prevention. Therefore, the alarm sound that there is a rear obstacle, and the drive the motor to rotate the shaft gear 15 of the motor, which in turn rotates the arc-shaped rack 13 which is pin-coupled with the lever 11 by hand By operating the brakes to stop the car, a simple configuration to prevent damage due to the collision of the car at the same time to protect the rear horse and also has the effect of preventing damage to other cars or buildings.
