본 고안은 차량용 발전장치에 관한 것으로, 특히 밧데리의 충전상태에 따라 발전기를 선택적으로 구동시키도록 된 발전장치에 관한 것이다.The present invention relates to a vehicle power generation device, and more particularly to a power generation device to selectively drive the generator according to the state of charge of the battery.
종래의 차량용 발전장치는 일련의 동력전달 수단에 의하여 배터리의 충전상태에 관계없이 엔진구동과 동시에 발전기가 구동되게 되어 있다. 따라서, 밧데리의 충전상태가 양호하여 충전시킬 필요가 없는 경우에도 발전기가 구동되어 그 발전기의 구동에 따른 불필요한 엔진출력의 낭비와 연료소모의 문제를 안고 있었다.In the conventional vehicle power generator, a generator is driven at the same time as the engine is driven by a series of power transmission means regardless of the state of charge of the battery. Therefore, even when the battery is in a good state of charge and does not need to be charged, the generator is driven, which causes unnecessary engine output waste and fuel consumption due to the driving of the generator.
본 고안은 상기한 사정을 감안하여 안출된 것으로서, 밧데리의 충전상태에 따라 발전기를 선택적으로 구동함으로써, 엔진의 에너지 효율을 높일 수 있도록 된 자동차용 발전장치를 제공함에 그 목적이 있다.The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a power generator for an automobile that can increase the energy efficiency of an engine by selectively driving a generator according to a state of charge of a battery.
상기 목적을 실현하기 위한 본 고안에 따른 자동차용 발전장치는 엔진의 구동력을 이용하여 소정의 전압을 생성하는 발전기와, 밧데리의 충전전압을 검출하는 전압센서, 이 전압센서에 의한 감지전압에 따라 스위치 구동부를 제어하는 제어부 및, 상기 스위치 구동부에 의해 구동되는 마그네틱 스위치를 포함하여 구성되고, 상기 발전기는 상기 마그네틱 스위치가 동작할 때 회전자가 회전축과 분리되도록 구성된 것을 특징으로 한다.Automotive power generation apparatus according to the present invention for achieving the above object is a generator for generating a predetermined voltage using the driving force of the engine, a voltage sensor for detecting the charge voltage of the battery, the switch according to the detected voltage by the voltage sensor And a magnetic switch driven by the switch driver, wherein the generator is configured such that the rotor is separated from the rotating shaft when the magnetic switch is operated.
이하, 도면을 참조하여 본 고안에 따른 실시예를 설명한다.Hereinafter, with reference to the drawings will be described an embodiment according to the present invention.
제1도는 본 고안의 1실시예에 따른 자동차용 발전장치를 나타낸 구성도로, 도면에서 참조번호 1은 충방전용 밧데리이고, 2는 시동 스위치, 3은 이 시동 스위치(2)가 온(ON)되게 되면 밧데리의 출력전압을 감지하여 출력전압이 일정 이상으로 되면 소정 레벨의 감지신호를 출력하는 전압센서, 6은 마그네틱 스위치로서, 이는 예컨대 하이레벨의 전기적 신호가 인가되면 자기장 형성에 따른 힘에 의해 스프링의 탄력을 누르고 회전자(73)를 클러치판(75)측으로 슬라이딩시킴으로써 상기 회전자(73)를 회전축(71)의 클러치판(75)과 결합시키게 된다.1 is a block diagram showing a power generation device for a vehicle according to an embodiment of the present invention, in the drawing, reference numeral 1 is a battery for charging and discharging, 2 is a start switch, and 3 is a start switch 2 to be turned on. When the output voltage of the battery is detected and the output voltage exceeds a certain level, the voltage sensor outputs a detection signal of a predetermined level, and 6 is a magnetic switch. By pressing the elasticity and sliding the rotor 73 to the clutch plate 75 side to couple the rotor 73 to the clutch plate 75 of the rotary shaft 71.
또한 참조번호 4는 상기 전압센서(3)로부터 감지신호가 인가되면 예컨대 인가된 신호가 하이레벨인 경우 마그네틱 스위치(6)를 구동시키기 위한 제어신호를 발생하는 제어부로서의 CPU이고, 5는 상기 CPU(4)의 명령에 따라 마그네틱 스위치(6)를 구동시키는 스위치 구동부, 7은 발전기(Alternator), 8은 자동차의 크랭크축과 벨트등에 의해 기계적으로 결합된 풀리로서, 여기서 발전기(7)는 상기 풀리(8)와 일체로 형성됨과 더불어 일단에 클러치판(75)이 구비된 회전축(71)과, 상기 마그네틱 스위치(6)에 의해 클러치판(75)과 밀착됨으로써 풀리(8)의 회전시 함께 회전하는 회전자(73)를 갖추고 있다.Further, reference numeral 4 denotes a CPU as a controller which generates a control signal for driving the magnetic switch 6 when the detection signal is applied from the voltage sensor 3, for example, when the applied signal is at a high level. Switch drive unit for driving the magnetic switch 6 in accordance with the command of 4), 7 is an alternator, 8 is a pulley mechanically coupled by the crankshaft and belt of the car, where the generator 7 is the pulley ( 8 is formed integrally with the rotary shaft 71 provided with a clutch plate 75 at one end, and the magnetic switch 6 is in close contact with the clutch plate 75 to rotate together when the pulley 8 rotates. The rotor 73 is provided.
즉, 상기한 구성에 있어서는 운전자가 시동을 걸게 되면 밧데리의 전압은 비교기의 비반전 단자에 입력되고, 저항 R1과 R2에 의해 분압된 기준전압이 반전단자에 각각 입력된다. 이때, 기준전압은 밧데리(1)가 적정수준으로 충전되었을 때의 전압으로 설정되게 된다.That is, in the above configuration, when the driver starts up, the voltage of the battery is input to the non-inverting terminal of the comparator, and the reference voltage divided by the resistors R 1 and R 2 is input to the inverting terminals, respectively. At this time, the reference voltage is set to the voltage when the battery 1 is charged to an appropriate level.
그리고, 전압센서(3)에 입력되는 밧데리 전압이 기준전압보다 낮게 되면 상기 전압센서(3)로부터 하이레벨의 검출전압이 출력되게 되고 CPU는 스위치 구동부(5)를 구동시키게 된다. 따라서, 스위치 구동부(5)에 의해 마그네틱 스위치(6)가 온(ON) 상태가 되어 자기장 형성에 따른 힘에 의해 회전자(73)가 슬라이딩 되면서 회전축(71)의 클러치판(75)과 결합되게 됨으로써, 발전기(7)가 구동되어 발전동작을 실행하게 된다.When the battery voltage input to the voltage sensor 3 becomes lower than the reference voltage, a high level detection voltage is output from the voltage sensor 3, and the CPU drives the switch driver 5. Accordingly, the magnetic switch 6 is turned on by the switch driving unit 5 so that the rotor 73 is slid by the force according to the magnetic field to be coupled to the clutch plate 75 of the rotation shaft 71. As a result, the generator 7 is driven to execute the power generation operation.
한편, 밧데리(1)가 충전되어 밧데리 전압이 기준전압 이상으로 되게 되면 전압센서(3)로부터의 출력은 로우레벨로 되고 CPU(4)는 스위치 구동부(5)를 제어하여 마그네틱 스위치(6)를 오프(OFF)시키게 된다. 따라서, 이때는 마그네틱 스위치(6)내에 있는 스프링의 복원력에 의해 클러치판(75)과 회전자(73)가 분리되게 됨으로써 발전기(7)에 의한 엔진부하가 제거된다.On the other hand, when the battery 1 is charged and the battery voltage becomes higher than the reference voltage, the output from the voltage sensor 3 becomes low level, and the CPU 4 controls the switch driver 5 to control the magnetic switch 6. It will be turned OFF. Therefore, at this time, the clutch plate 75 and the rotor 73 are separated by the restoring force of the spring in the magnetic switch 6, so that the engine load by the generator 7 is removed.
따라서, 상기 실시예에 의하면 밧데리의 충전 상태에 따라 발전기가 선택적으로 구동되게 됨으로써, 발전기의 구동에 따른 엔진부하를 최소한도로 절감시켜 엔진의 에너지 효율을 높일 수 있게 된다.Therefore, according to the embodiment, the generator is selectively driven according to the state of charge of the battery, thereby reducing the engine load according to the driving of the generator to the minimum, thereby increasing the energy efficiency of the engine.
또한, 본 고안은 상기 실시예에 한정되지 않고 본 고안의 기술적 요지를 벗어나지 않는 범위내에서 다양하게 변형 실시할 수 있다.In addition, the present invention is not limited to the above embodiments and can be variously modified within the scope not departing from the technical gist of the present invention.
이상 설명한 바와 같이 본 고안에 의하면, 엔진에 의한 발전기의 불필요한 구동을 방지할 수 있도록 된 차량용 발전장치를 실현할 수 있게 된다.As described above, according to the present invention, it is possible to realize a vehicle power generator that can prevent unnecessary driving of a generator by an engine.
