Description

스타터 모터의 손상방지장치Damage prevention device of starter motor

본 고안은 엔진을 시동하는 스타터모터의 손상방지장치에 관한 것이다.The present invention relates to a damage preventing device of a starter motor for starting an engine.

내연기관인 자동차 엔진은 자가시동을 할 수 없기 때문에 시동을 걸때는 외력에 의해 크랭크 축을 회전시켜야 하기 때문에 도 2에서와 같이 축전지전원(11)에 의해 시동장치(12)를 구동시키게 된다.Since the automobile engine, which is an internal combustion engine, cannot start itself, the starter 12 is driven by the battery power source 11 as shown in FIG. 2 because the crankshaft must be rotated by an external force when starting the engine.

상기 시동장치(12)는 스타터모터와 모터의 힘을 엔진으로 전달하는 동력전달기구로 이루어져 있는데 시동장치(12)는 일반적인 전기기기와는 달리 안전사용시간이 매우 짧아서 (보통 수십초 이내) 장시간 사용하면 모터 손상의 원인이 되며 통상 엔진의 시동이 걸린 다음에 스타터 스위치를 돌리면 기어가 맞부딪쳐서 심한 소음이 나고 스타터 하우징을 파손하는 경우가 발생되므로 주의하지 않으면 안된다.The starter 12 is composed of a power transmission mechanism for transmitting the power of the starter motor and the motor to the engine. The starter 12 has a very short safe use time (usually within several tens of seconds), unlike general electric devices. Doing so may cause damage to the motor, and turning the starter switch after the engine has been started will normally cause gears to strike, resulting in severe noise and damage to the starter housing.

그럼에도 불구하고 능숙치 못한 운전자는 엔진의 시동이 걸린 것을 모르고 시동키 스위치를 계속 돌리므로써 스타터모터의 손상을 가져오는 일이 종종 발생하는 문제점이 있다.Nevertheless, the inexperienced driver often does not know that the engine has been started and causes the starter motor to be damaged by continuously turning the ignition switch.

이에 본원 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 엔진의 시동이 일단 걸린상태에서는 스타터 모터에의 전원공급을 원천적으로 차단하므로써 시동키스위치의 재작동시 발생하는 스타터모터 구동에 따른 손상을 방지할 수 있는 스타터모터의 손상방지장치를 제공하는데 있다.The present invention has been proposed in view of the above problems, and its purpose is to stop the power supply to the starter motor once the engine is started. It is to provide a damage preventing device of the starter motor that can prevent the damage caused.

이하 본 고안의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 고안에 의한 스타터모터의 손상방지장치를 나타내는 도면으로 도면에 있어서 부호 1은 엔진이며 부호 2는 엔진을 시동하는 시동장치의 스타터모터이다.1 is a view showing a damage preventing apparatus of a starter motor according to the present invention, in which 1 is an engine and 2 is a starter motor of a starter for starting an engine.

상기 스타터모터(2)는 배터리전원(3)에 의해 구동되며 시동키스위치(4)의 온조작에 의해 전원회로가 접속된다.The starter motor 2 is driven by the battery power source 3 and is connected to a power supply circuit by the on operation of the start key switch 4.

상기 시동키스위치(4)와는 직렬회로로 회로단락스위치(5)가 접속되며 상기 회로단락스위치(5)의 온ㆍ오프는 솔레노이드(6)의 작동에 의해 이루어진다.The circuit short switch 5 is connected to the start key switch 4 in a series circuit, and the circuit short switch 5 is turned on and off by the operation of the solenoid 6.

도면 중 부호 7은 타이밍 벨트로서 엔진(1)이 시동되면 타이밍 벨트(7)는 항상 회전하게 된다.In the figure, reference numeral 7 denotes a timing belt. When the engine 1 starts, the timing belt 7 always rotates.

상기 타이밍벨트(7)의 표면에는 회전감지센서(8)가 설치되어 그의 회전로울러(8a)가 타이밍벨트(7)와의 마찰력에 의해 회전하게 되면 그 움직임을 신호로 출력하여 전자제어장치(9)에 인가하며 전자제어장치(9)는 상기 솔레노이드(6)를 작동시켜 회로단락스위치(5)를 오프상태로 전환하며 회전감지센서(8)로부터 타이밍벨트(7)의 움직임이 검출되지 않으면 솔레노이드(6)를 오프시켜 회로단락스위치(5)를 온상태로 전환한다.The rotation detecting sensor 8 is installed on the surface of the timing belt 7, and when the rotary roller 8a is rotated by the frictional force with the timing belt 7, the motion is output as a signal to output the electronic controller 9. And the electronic control device 9 operates the solenoid 6 to turn the circuit short switch 5 off and if the movement of the timing belt 7 is not detected from the rotation sensor 8, the solenoid ( 6) is turned off to turn the circuit short switch 5 on.

이하에 본 고안의 작동에 대하여 구체적으로 설명한다.Hereinafter, the operation of the present invention will be described in detail.

시동키스위치(4)를 온위치로 작동하면 스타터모터(2)에 배터리전원(3)이 공급되어 엔진(1)이 시동된다.When the starter key switch 4 is operated to the on position, the battery power source 3 is supplied to the starter motor 2 to start the engine 1.

엔진(1)의 시동이 성공하면 시동키스위치(4)로부터 손을 떼게되며 이에따라 전원회로가 오프되어 스타터모터(2)에의 전원공급이 끊긴다.If the engine 1 is successfully started, the hand is released from the start key switch 4, and accordingly, the power supply circuit is turned off so that the power supply to the starter motor 2 is cut off.

엔진(1)이 시동되었으므로 타이밍벨트(7)가 회전하게 되며 타이밍벨트(7)의 움직임은 회전감지센서(8)를 통해 감지되어 전자제어장치(9)에 보내진다.Since the engine 1 is started, the timing belt 7 rotates, and the movement of the timing belt 7 is sensed through the rotation sensor 8 and sent to the electronic controller 9.

전자제어장치(9)는 이 신호를 받아 솔레노이드(6)를 작동시켜 회로단락스위치(5)를 오프시키므로써 배터리전원 공급회로를 원천적으로 차단한다.The electronic control unit 9 receives this signal and operates the solenoid 6 to turn off the circuit short switch 5, thereby essentially blocking the battery power supply circuit.

이때 만일 운전자가 엔진시동이 걸리지 않은 것으로 오해하여 시동키스위치(4)를 돌려 재시동을 시도하더라도 회로단락스위치(5)에 의해 전원공급회로가 단락되어 있기 때문에 스타터모터(2)는 구동되지 않게된다.At this time, even if the driver misunderstands that the engine is not started and tries to restart by turning the ignition key switch 4, the starter motor 2 is not driven because the power supply circuit is short-circuited by the short circuit switch 5. .

그러나 만일 처음부터 엔진시동이 걸리지 않았다면 타이밍벨트는 회전하지 아니하며 그 신호를 검출하여 솔레노이드가 오프되므로써 회로단락스위치(5)는 전원회로를 온 접속하는 상태가 되어 재시동에 의해 스타터모터(4)가 구동되어지게 된다.However, if the engine is not started from the beginning, the timing belt does not rotate and the solenoid is turned off by detecting the signal, so that the circuit short switch 5 is turned on and the starter motor 4 is driven by restart. Will be.

이상과 같은 본원 고안에 의하면 엔진의 시동을 타이밍벨트의 움직임을 통해 검출한후 스타터모터 구동을 위한 배터리전원회로를 단락하도록 하므로써 엔진이 시동된 상태에서 이를 모르고 재시동을 시도하더라도 스타터모터가 구동되지 아니하게 되므로 스타터모터의 손상을 방지하게 되는 효과가 있다.According to the present invention as described above, by detecting the start of the engine through the movement of the timing belt to short-circuit the battery power circuit for driving the starter motor, the starter motor is not driven even if the engine is started without knowing this. It is effective to prevent damage to the starter motor.
