Description

자동차의 비상등 점멸장치Car emergency light flasher

본 고안은 자동차의 비상등에 관한 것으로, 특히 자동차의 주행중에 급정지를 위하여 브레이크페달을 밟았을 때에 비상등이 자동으로 점멸되게 하는 자동차의 비상등 점멸장치에 관한 것이다.The present invention relates to an emergency light of an automobile, and more particularly, to an emergency light flasher of a vehicle that causes the emergency light to flash automatically when the brake pedal is pressed for sudden stop while driving the vehicle.

자동차에 장착된 브레이크장치는 운행되는 자동차를 제동시키는 제동장치로, 운전자가 브레이크페달을 밟았을 때에 페달의 답력이 유압을 발생시켜 자동차바퀴의 휠일측에 장착된 브레이크디스크를 구동시키므로, 회전중인 바퀴를 제동시키는 것이다.A brake device mounted on a vehicle is a brake device for braking a moving vehicle. When the driver presses the brake pedal, the pedal force generates hydraulic pressure to drive the brake disc mounted on one side of the wheel of the automobile wheel. To brake.

주행중인 자동차를 제동시키기 위하여 브레이크페달을 밟으면, 브레이크페달의 일측에 장착된 브레이크스위치가 온되고, 브레이크스위치는 자동차의 후미에 구성된 브레이크등을 점등시킨다. 브레이크등은 운전자가 브레이크페달을 밟았을 때에 온되어 점등되므로, 후방으로부터 주행되는 자동차에 급정거를 알려주는 기능을 한다.When the brake pedal is pressed in order to brake a vehicle in motion, a brake switch mounted on one side of the brake pedal is turned on, and the brake switch lights a brake light configured at the rear of the vehicle. Since the brake light is turned on and turned on when the driver presses the brake pedal, the brake light serves as a function of informing a sudden stop of a vehicle running from the rear.

이와 동시에 종래에 브레이크페달의 답력을 브레이크장치에 전달시켜 자동차의 바퀴를 제동시키는 브레이크장치는 첨부된 도 1의 유압브레이크의 작동도에서, 브레이크페달을 밟으면, 오일탱크내의 오일(1)이 오일공급관(2)을 통해 실린더(5)로 공급되고, 실린더(5)내의 오일의 유압은 피스톤(6)을 밀어내게 되고, 피스톤(6)은 브레이크디스크(4)의 양측에 구비된 디스크헤드(3)를 밀어내어 브레이크디스크(4)를 제동시킨다. 이때, 디스크헤드(3)에는 패드가 구비되어 있어 실제로 브레이크디스크(4)를 패드가 눌러주어 제동을 시키는 기능을 한다.At the same time, the brake device for braking the wheels of a vehicle by transmitting the pedal pedal effort to the brake device in the related art, in the operation diagram of the hydraulic brake of FIG. 1 attached, when the brake pedal is pressed, the oil 1 in the oil tank becomes an oil supply pipe. (2) is supplied to the cylinder (5), the hydraulic pressure of the oil in the cylinder (5) pushes out the piston (6), the piston (6) is the disk head (3) provided on both sides of the brake disc (4) ) To brake the brake disc (4). At this time, the disk head 3 is provided with a pad, so that the pad actually presses the brake disk 4 to perform braking.

이와 같이 종래에는 운전자가 브레이크페달을 밟았을 때에 후방에서 주행되는 자동차의 운전자에게 브레이크등만을 점등시키므로, 후방의 운전자가 용이하게 인식하기에는 미흡한 점이 있었다. 즉, 주간에 자동차를 주행중에 브레이크페달을 밟았을 때에 주위가 밝거나 후광이 있으면, 브레이크등의 점등여부를 용이하게 인식할 수 없어 추돌사고를 일으킬 위험이 있었고, 또한 야간에는 미등의 점등과 동시에 차폭등이 점등되고, 차폭등에는 브레이크페달을 밟았을 때에 별도의 브레이크등이 점등되므로, 주행중에 차폭등이 점등된 상태에서 브레이크등이 동시에 점등되므로, 운전자가 브레이크등의 점등상태를 용이하게 인식하지 못하여 추돌사고를 일으킬 위험이 내재된 문제가 있었다.As described above, when the driver presses the brake pedal, only the brake light is turned on to the driver of the vehicle running behind the vehicle, so that the driver behind the vehicle is not easily recognized. That is, if the brake pedal is pressed while driving a car during the day, if the surrounding light is bright or there is a halo, the brake light may not be recognized easily, and there is a risk of causing a crash. Since the vehicle's side light is turned on and the brake light is turned on when the brake pedal is pressed, the driver lights up the brake light easily while the vehicle's side light is on while driving. There was a problem inherent in the risk of causing a collision accident.

본 고안은 상기와 같은 문제를 감안하여 안출된 것으로, 운전자가 제동을 위하여 브레이크페달을 밟았을 때에 비상등이 자동으로 점멸되도록하여 후방의 운전자가 용이하게 인식할 수 있게 한 자동차의 비상등 점멸장치를 제공하기 위한 것이 목적이다.The present invention is conceived in view of the above problems, to provide an emergency light flashing device of the vehicle so that the emergency light flashes automatically when the driver presses the brake pedal for braking so that the driver behind the car can easily recognize. The purpose is to.

본 고안은 상기의 목적을 달성하기 위하여, 자동차의 브레이크페달을 밟았을 때에 브레이크등을 점등시키는 장치에 있어서, 브레이크페달의 답력으로 변화되는 유압을 감지하는 유압감지센서와, 상기 유압감지센서에서 감지된 유압신호가 (+)단을 통해 인가되고, (-)단으로는 기준되는 유압에 관한 전압을 발생시키는 기준전압을 인가받아 입력된 신호를 비교하는 비교기와, 상기 브레이크페달의 일측에 구비되어 브레이크페달을 밟았을 때에 온되어 배터리전원을 도통시키는 브레이크스위치와, 상기 비교기로부터 입력된 비교신호와 브레이크스위치로부터 인가된 배터리전원을 논리곱으로 연산하는 논리곱게이트와, 상기 논리곱게이트로부터 출력된 논리신호로 배터리전원을 온 또는 오프시키는 릴레이와, 상기 릴레이의 스위칭으로 인가된 배터리전원을 일정시간간격으로 온 또는 오프시키는 블링크릴레이와, 상기 블링크릴레이의 스위칭으로 점멸되는 비상등을 포함하여 이루어진 것이 특징이다.The present invention, in order to achieve the above object, in the device for turning on the brake light when the brake pedal of the vehicle, the hydraulic pressure sensor for detecting the hydraulic pressure is changed by the pedal pedal effort, and the hydraulic pressure sensor detects And a comparator for comparing the input signals by applying a reference voltage for generating a voltage related to the reference hydraulic pressure, and a side of the brake pedal. A brake switch which is turned on when the brake pedal is pressed and conducts battery power, a logical AND gate for calculating a logical product of the comparison signal input from the comparator and the battery power applied from the brake switch, and an output from the logical AND gate; A relay for turning on or off the battery power with a logic signal and a battery applied by switching the relay; Is characterized by consisting of, including a blink relay for turning on or off at predetermined intervals in a circle, emergency light is blinking in blink switching of said relay.

이하, 첨부된 도면에 의거하여 본 고안에 관하여 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 자동차의 브레이크페달을 작동시킬 때에 비상등을 점멸시키는 장치의 회로구성도이다. (다음에 설명되는 종래와 동일한 구성에 대해서는 동일한 부호를 기재한다.)2 is a circuit diagram of a device for blinking an emergency light when operating a brake pedal of an automobile. (The same code | symbol is described about the structure same as the conventional one demonstrated below.)

유압센서(10)는 오일의 유압으로 작동되는 실린더(5)의 내측에 장착되어 유압을 감지하는 데, 유압의 변화에 따라 출력되는 전압신호가 달라진다. 즉, 유압센서(10)는 감지되는 유압이 커지면 저항이 작아져 도통되는 배터리전원(B+)의 전압신호가 커지고, 감지되는 유압이 작아지면 저항이 커져 도통되는 배터리전원(B+)의 전압신호가 작아진다.The oil pressure sensor 10 is mounted inside the cylinder 5 which is operated by oil pressure of oil to detect oil pressure, and the output voltage signal varies according to the change of oil pressure. That is, the oil pressure sensor 10 increases the voltage signal of the battery power (B +) that is conducted when the oil pressure is increased and the resistance decreases, and increases the voltage signal of the battery power (B +) that is conducted when the oil pressure is reduced, the resistance is increased. Becomes smaller.

비교기(12)는 상기 유압센서(10)로부터 (+)단으로 입력되는 전압신호와 (-)단으로 입력되는 기준전압(V1)을 비교하여 비교된 신호를 출력시킨다. 즉, 유압센서(10)에서 출력되는 전압신호와 기준전압(V1)으로부터 입력되는 신호를 비교하여 비교신호를 출력시키는 데, 기준전압(V1)보다 유압센서(10)로부터 입력되는 전압신호가 크면, 비교기(12)의 비교신호는 로우상태가 되고, 이와 반대로 기준전압(V1)보다 유압센서(10)로부터 입력되는 전압신호가 작으면, 비교기(12)의 비교신호는 하이상태가 된다. 따라서, 비교기(12)는 기준전압(V1)의 전압크기에 따라 유압의 증감을 감지하는 유압센서(10)의 저항변위를 조정할 수 있다.The comparator 12 compares the voltage signal input from the hydraulic sensor 10 to the (+) stage and the reference voltage V1 input to the (-) stage, and outputs the compared signal. That is, the voltage signal output from the hydraulic sensor 10 and the signal input from the reference voltage V1 are compared to output a comparison signal. When the voltage signal input from the hydraulic sensor 10 is greater than the reference voltage V1, The comparison signal of the comparator 12 is in a low state. On the contrary, when the voltage signal input from the hydraulic sensor 10 is smaller than the reference voltage V1, the comparison signal of the comparator 12 is in a high state. Accordingly, the comparator 12 may adjust the resistance displacement of the oil pressure sensor 10 that detects the increase or decrease of the oil pressure according to the voltage magnitude of the reference voltage V1.

브레이크스위치(14)는 브레이크페달의 일측에 장착되어 브레이크페달을 밟으면 온되고, 브레이크페달을 놓으면 오프된다. 브레이크스위치(14)가 온되면 배터리전원(B+)을 도통시키고, 오프되면 배터리전원(B+)을 차단시킨다.The brake switch 14 is mounted on one side of the brake pedal and is turned on when the brake pedal is pressed, and turned off when the brake pedal is released. When the brake switch 14 is turned on, the battery power B + is turned on, and when the brake switch 14 is turned off, the battery power B + is cut off.

논리곱게이트(16)는 상기 브레이크스위치(14)를 통해 인가된 배터리전원(B+)의 전압신호와 비교기(12)로부터 입력된 비교신호를 논리곱으로 연산하여 연산된 논리신호를 출력시킨다. 논리곱게이트(16)는 입력되는 신호가 모두 하이신호이면, 논리연산된 논리신호는 하이신호가 출력되고, 입력되는 신호중에 하나라도 로우신호가 입력되면 출력되는 논리신호는 로우신호를 출력시킨다.The AND gate 16 outputs a logic signal calculated by performing a logical AND on the voltage signal of the battery power source B + applied through the brake switch 14 and the comparison signal input from the comparator 12. If the input signal is all high signals, the logical product gate 16 outputs a high signal, and if any of the input signals is a low signal, the output logic signal outputs a low signal.

릴레이(18)는 코일부(18a)와 릴레이스위치(18b)로 나뉘어져 있고, 상기 논리곱게이트(16)의 출력단이 릴레이(18)의 코일부(18a)에 접속되어 있으며, 릴레이스위치(18b)의 일단에는 배터리전원(B+)이 연결되어 있다. 릴레이(18)는 논리곱게이트(16)에서 하이신호가 출력되면, 코일부(18a)가 온되어 전기장을 갖게되고, 코일부(18a)의 전기장은 대응되게 구성된 릴레이스위치(18b)를 온시켜 배터리전원(B+)을 도통시킨다.The relay 18 is divided into a coil portion 18a and a relay switch 18b, and the output terminal of the logical product gate 16 is connected to the coil portion 18a of the relay 18, and the relay switch 18b One end of the battery power (B +) is connected. When the high signal is output from the logical product gate 16, the relay 18 turns on the coil unit 18a to have an electric field, and the electric field of the coil unit 18a turns on the corresponding relay switch 18b. Turn on battery power (B +).

블링크릴레이(20)는 코일부(20a)와 릴레이스위치(20b)로 구성되고, 상기 릴레이(18)의 릴레이스위치(18b)에 블링크릴레이(20)의 코일부(20a)가 접속되고, 블링크릴레이(20)의 릴레이스위치(20b)에는 배터리전원(B+)이 연결되어 있다.The blink relay 20 includes a coil part 20a and a relay switch 20b, and a coil part 20a of the blink relay 20 is connected to a relay switch 18b of the relay 18, and a blink relay The battery power source B + is connected to the relay switch 20b of 20.

비상등(30-33)은 자동차의 전후방일측에 각각 구성되어 자동차의 긴급상황이나 고장 또는 각종의 비상상황을 표시하는 램프로, 별도로 구비되어 있는 비상등스위치(미도시)의 조작으로 점멸시킬 수 있고, 상기 블링크릴레이(20)의 릴레이스위치(20b)에 접속되어 블링크릴레이(20)의 온 또는 오프로 일정시간간격으로 점멸된다.Emergency light 30-33 is a lamp that is configured on each side of the front and rear of the car to indicate the emergency or breakdown of the car or various emergency situations, and can be flashed by the operation of an emergency light switch (not shown) provided separately. It is connected to the relay switch 20b of the blink relay 20 and blinks at a predetermined time interval when the blink relay 20 is turned on or off.

이와 같이 구성된 브레이크페달의 작동으로 비상등을 점멸시키는 장치에 관한 작용을 설명하면 다음과 같다.Referring to the operation of the device for flashing the emergency light by the operation of the brake pedal configured as described above are as follows.

자동차의 운전자가 자동차를 주행중에 위급상황 등으로 인하여 브레이크페달을 밟게 되면, 브레이크페달의 일측에 구비된 브레이크스위치(14)는 온되고, 브레이크페달의 답력이 유압으로 전달되어 실린더(5)에 구성된 유압센서(10)가 오일(1)의 유압을 감지한다. 유압센서(10)에서 감지된 감지신호는 비교기(12)의 (+)단으로 인가되어 (-)단에 연결된 기준전압(V1)으로부터 인가된 전압신호와 비교된다. 비교기(12)의 (-)단으로 인가되는 기준전압(V1)은 유압센서(10)에서 감지하는 기준되는 전압으로 유압센서(10)의 감지범위를 제한시킨다. 즉, 유압센서(10)에서 감지된 감지신호가 기준전압(V1)의 전압신호보다 크면 비교기(12)의 출력단으로는 하이신호가 출력되고, 유압센서(10)에서 감지된 감지신호가 기준전압(V1)보다 작으면 비교기(12)의 출력단으로는 로우신호가 출력된다.When the driver of the vehicle presses the brake pedal due to an emergency or the like while driving the vehicle, the brake switch 14 provided on one side of the brake pedal is turned on, and the pedal pedal power is transmitted hydraulically to constitute the cylinder 5. The hydraulic pressure sensor 10 detects the oil pressure of the oil 1. The sensing signal sensed by the hydraulic sensor 10 is applied to the (+) end of the comparator 12 and compared with the voltage signal applied from the reference voltage V1 connected to the (-) end. The reference voltage V1 applied to the negative end of the comparator 12 limits the detection range of the hydraulic sensor 10 to the reference voltage detected by the hydraulic sensor 10. That is, when the detection signal detected by the hydraulic sensor 10 is greater than the voltage signal of the reference voltage V1, a high signal is output to the output terminal of the comparator 12, and the detection signal detected by the hydraulic sensor 10 is a reference voltage. If less than V1, a low signal is output to the output terminal of the comparator 12.

비교기(12)에서 출력된 비교신호는 논리곱게이트(16)의 입력단으로 인가되어 상기 브레이크스위치(14)로부터 인가된 배터리전원(B+)과 논리곱으로 연산된다. 논리곱게이트(16)는 브레이크스위치(14)가 온상태이고, 비교기(12)의 출력이 하이신호이면 하이신호를 출력시킨다. 논리곱게이트(16)에서 출력된 하이신호는 릴레이(18)의 코일부(18a)로 인가되어 코일부(18a)가 전기장을 갖도록 한다. 코일부(18a)에서 발생된 전기장은 대응되게 구성된 릴레이스위치(18b)를 온시켜 배터리전원(B+)을 도통시킨다.The comparison signal output from the comparator 12 is applied to the input terminal of the logical AND gate 16 and is calculated by logical AND with the battery power source B + applied from the brake switch 14. The AND gate 16 outputs a high signal when the brake switch 14 is on and the output of the comparator 12 is a high signal. The high signal output from the AND gate 16 is applied to the coil portion 18a of the relay 18 so that the coil portion 18a has an electric field. The electric field generated in the coil portion 18a turns on the correspondingly configured relay switch 18b to conduct the battery power source B +.
