차량의 브레이크 패드 교환시기 알림장치 {Apparatus for indicating the time of exchanging a brake pad for vehicles}Applicator for indicating the time of exchanging a brake pad for vehicles}

본 발명은 차량의 브레이크 패드 교환시기 알림장치에 관한 것으로서 특히, 광소자와 광센서를 이용하여 전자적으로 교환시기를 운전자에게 알리도록 하고, 운전자에게 브레이크 패드의 교체시기를 정확히 알려주도록 함으로써 운전자의 편의성을 향상시키고 교체시기가 너무 이르거나 지체되어 발생하는 비용증가 및 사고의 위험을 방지할 수 있도록 하는 차량의 브레이크 패드 교환시기 알림장치에 관한 것이다.The present invention relates to a brake pad replacement time notification device of a vehicle, and in particular, to inform the driver of the replacement time electronically by using an optical device and an optical sensor, and to inform the driver accurately when to replace the brake pads, the driver's convenience The present invention relates to a brake pad replacement timing notification device of a vehicle, which improves the cost and prevents an increase in cost and an accident caused by too soon or delayed replacement.

차량에 사용되는 브레이크는 보통 드럼 브레이크와 디스크 브레이크가 사용되며, 특히 디스크 브레이크는 디스크가 노출되어 있으므로 열작용이 좋고, 그 구조가 간단하므로 패드의 교환 및 손질이 용이하여 많이 사용되고 있다.A brake used in a vehicle is usually a drum brake and a disc brake, and in particular, the disc brake has a good heat action because the disc is exposed, and its structure is simple, so that the pads are easily replaced and cleaned.

도 1은 일반적인 디스크 브레이크를 나타내는 개략도로서, 운전자가 브레이크 페달을 밟으면 유압이 작용하여 캘리퍼 내의 실린더(1)에 유압이 전달되어 피스톤(2)이 브레이크 패드(3)를 화살표 방향으로 이동시켜 브레이크 디스크(4)를 압착하여 브레이크 작용을 하게 된다.1 is a schematic diagram showing a general disc brake. When the driver presses the brake pedal, the hydraulic pressure acts, the hydraulic pressure is transmitted to the cylinder 1 in the caliper, and the piston 2 moves the brake pad 3 in the direction of the arrow to brake disk. (4) is pressed to brake.

상기 브레이크 패드(3)는 소모품으로서 사용 수명이 있어서 일정시간 사용한 후에는 교체가 필요하다. 종래에는 상기 브레이크 패드(3)를 교체함에 있어서는 운전자가 임의로 그 시기를 판단하여 교체하거나, 브레이크 패드(3) 뒷면에 철심을넣어서 브레이크 작동시 소음을 운전자가 판단하여 교체하는 방법이 있다.The brake pad 3 has a service life as a consumable and needs to be replaced after a certain time of use. Conventionally, in replacing the brake pad 3, the driver arbitrarily determines the time of replacement, or replaces the brake pad 3 by inserting an iron core into the rear of the brake pad 3 so as to determine and replace the noise when the brake is operated.

그러나 운전자가 임으로 그 시기를 판단하여 교체하는 경우에는 운전자의 사용습관에 따라 브레이크 패드를 교체하는 타입에 따라, 너무 이르게 교체하면 자원 낭비 및 비용증가의 문제가 있고, 너무 늦게 교체하면 제동성능 및 브레이크 디스크에 이상을 가져오는 문제점이 있다.However, if the driver decides to replace the brake pads at the time, the brake pads are replaced according to the driver's usage habits. If the driver is replaced too early, there is a problem of waste of resources and increase of cost. There is a problem with the disk.

또한 상기와 같은 철심에 의한 판단에 의하여 교체하는 경우에는 그 교체시기가 지체하면 이상 소음이 장기간 발생하여 운전자 및 주변사람에게 불안감을 주는 문제점이 있었다.In addition, when the replacement by the judgment of the iron core as described above, if the replacement time is delayed, there was a problem that the abnormal noise occurs for a long time to the driver and people around.

본 발명은 상기의 결점을 해소하기 위한 것으로, 운전자에게 브레이크 패드의 교체시기를 정확히 알려주도록 함으로써 운전자의 편의성을 향상시키고 교체시기가 너무 이르거나 지체되어 발생하는 비용증가 및 사고의 위험을 방지할 수 있도록 하는 차량의 브레이크 패드 교환시기 알림장치를 제공하고자 한다.The present invention is to solve the above-mentioned shortcomings, it is possible to improve the driver's convenience by accurately telling the driver when to replace the brake pads and to prevent the cost increase and risk of accidents caused by too soon or delayed replacement time It is intended to provide a brake pad replacement time notification device of a vehicle.

도 2는 본 발명의 차량의 브레이크 패드 교환시기 알림장치를 나타내는 개략도이고, 도 3은 본 발명의 차량의 브레이크 패드 교환시기 알림장치의 브레이크 디스크를 나타내는 평면도로서, 본 발명은 실린더에 유압이 전달되어 피스톤이 양측의 브레이크 패드(20)를 이동시켜 브레이크 디스크(10)를 압착하여 브레이크 작용을 하는 디스크 브레이크에 있어서, 상기 일측의 브레이크 패드(20)의 부착부(21)에 설치되는 광소자(30)와; 타측의 브레이크 패드(20)의 부착부(21)의 상기 광소자(30)가 설치된 지점의 대향측에 설치되는 광센서(40)와; 상기 브레이크 디스크(10)에 외측에 상기 광소자(30)와 광센서(40)가 위치하는 곳의 원주를 따라 형성된 다수개의 홀(11)과; 상기 광소자(30)와 광센서(40)를 구동하는 전원부(50)와; 상기 광센서(40)에 연결되는 신호부(60)로 구성되는 것을 그 기술상의 특징으로 한다.Figure 2 is a schematic diagram showing a brake pad replacement time notification device of the vehicle of the present invention, Figure 3 is a plan view showing a brake disk of the brake pad replacement time notification device of the vehicle of the present invention, the invention is a hydraulic pressure is delivered to the cylinder In a disc brake in which a piston moves the brake pads 20 on both sides and compresses the brake disc 10 to act as a brake, an optical element 30 provided in the attachment portion 21 of the brake pad 20 on the one side. )Wow; An optical sensor 40 provided on an opposite side of a point where the optical element 30 of the attachment portion 21 of the brake pad 20 on the other side is installed; A plurality of holes (11) formed along the circumference of the place where the optical element (30) and the optical sensor (40) are located on the outside of the brake disc (10); A power supply unit 50 for driving the optical device 30 and the optical sensor 40; It is characterized by the technical features that the signal unit 60 is connected to the optical sensor 40.

상기 브레이크 디스크(10)의 홀은 그 원주를 따라 일정 간격으로 형성되며, 그 크기는 상기 광소자(30) 및 광센서(40)의 정도의 크기를 이루도록 하는 것이 바람직하다.The holes of the brake disc 10 are formed at regular intervals along the circumference thereof, and the size of the brake disc 10 may be about the size of the optical device 30 and the optical sensor 40.

상기한 바와 같이, 상기 광소자(30)와 광센서(40) 및 그 사이에 위치하는 브레이크 디스크(10)의 홀(11)은 일직선을 이루게 된다.As described above, the optical element 30 and the optical sensor 40 and the holes 11 of the brake disc 10 positioned therebetween form a straight line.

따라서, 브레이크 패드(20)가 마모되지 않은 상태에서는 상기 광소자(30)에서 발산된 빛은 상기 광센서(40)에 이르지 못하고 차단되어 있는 상태이나, 상기 브레이크 패드(20)가 마모되어 빛이 통과할 정도의 두께에 이르게 되면, 상기 광소자(30)에서 발산된 빛이 상기 광센서(40)에 이르게 되고, 그러면 상기 광센서(40)에 연결된 신호부(60)에서 신호를 발신함으로써, 운전자에게 브레이크 패드(20)의 교체시기를 알리는 것이다.Therefore, in the state where the brake pad 20 is not worn, the light emitted from the optical device 30 is blocked without reaching the optical sensor 40, but the brake pad 20 is worn and the light is blocked. When it reaches a thickness enough to pass through, the light emitted from the optical device 30 reaches the optical sensor 40, and then by sending a signal from the signal unit 60 connected to the optical sensor 40, Informing the driver of the replacement of the brake pad 20.

이상과 같은 본 발명은 운전자에게 브레이크 패드의 교체시기를 정확히 알려주도록 함으로써 운전자의 편의성을 향상시키고 교체시기가 너무 이르거나 지체되어 발생하는 비용증가 및 사고의 위험을 방지할 수 있도록 하는 효과가 있는 발명인 것이다.The present invention as described above has the effect of improving the driver's convenience by informing the driver precisely when to replace the brake pad and to prevent the cost increase and the risk of accidents caused by the replacement time too late or delayed will be.
