Description
본 고안은 에어백 작동신호를 이용한 전기자동차 안전장치에 관한 것으로서, 더욱 상세하게는 충돌로 인하여 전기자동차에 장착되어 있는 에어백 작동시 전기자동차의 동력으로 제공되는 모터의 전기를 차단함으로써 충돌시 전기 자동차의 안전성을 높일 수 있도록 하는 에어백 작동신호를 이용한 전기자동차 안전장치에 관한 것이다.The present invention relates to an electric vehicle safety device using an airbag operation signal, and more particularly, to cut off electric power of a motor provided by the power of an electric vehicle when an airbag mounted on an electric vehicle is operated due to a collision. The present invention relates to an electric vehicle safety device using an airbag operation signal for increasing safety.
종래 차량에 사용되고 있는 연료가 연소되면서 인체나 자연에 유해한 배가가스를 배출된다는 점을 감안하여 근래에 와서는 유해한 배기가스가 배출되지 않는 전기자동차가 등장하였다. 그리고 이는 최근에 와서 기술발전과 더불어 일반 자동차들과 한께 널리 보급되어 가고 있는 추세이다. 그리고 이러한 전기자동차에도 에어백 시스템을 장착하여 전기자동차고 안전사고, 즉 충돌사고시 운전자를 충돌로부터 보호한다.In view of the fact that the fuel used in the conventional vehicle is combusted to emit harmful exhaust gas harmful to the human body or nature in recent years, electric vehicles that do not emit harmful exhaust gas has emerged. And this is a trend that has recently been widely spread with general automobiles with technological development. The electric vehicle is also equipped with an airbag system to protect the driver from an accident in an electric vehicle safety accident, that is, a collision accident.
이러한 전기자동차에도 충돌사고시 안전을 고려하여 에어백 시스템이 장착되어 있는데, 에어백 시스템이 작동될 정도의 충돌사고시에도 전기자동차의 동력원인 모터에는 계속해서 동작전원이 공급되어 전기자동차가 계속해서 전진하기 때문에 전기자동차의 충돌력이 배가되는 결점이 있다.These electric vehicles are also equipped with an airbag system in consideration of safety in the event of a crash.In the event of a crash that causes the airbag system to operate, the motor, which is the power source of the electric vehicle, is continuously supplied with the operating power and the electric vehicle continues to move forward. The disadvantage is that the collision force of the car is doubled.
이에 본 고안은 상기한 바와 같은 종래의 결점을 해결하기 위해서 안출된 것으로, 충돌로 인하여 전기 자동차에 장착되어 있는 에어백 작동시 전기자동차의 동력으로 제공되는 모터의 전기를 차단함으로써 충돌시 전기자동차의 안전성을 높일 수 있도록 하는 에어백 작동신호를 이용한 전기자동차 안전장치를 제공하고자 하는데 그 목적이 있는 것이다.In order to solve the above-mentioned drawbacks, the present invention is designed to cut off the electric power of the motor provided by the power of the electric vehicle during the operation of the airbag mounted on the electric vehicle due to the collision. The purpose of the present invention is to provide an electric vehicle safety device using an airbag operation signal to increase the level.

도 1은 본 고안에 따른 구성도이다.1 is a block diagram according to the present invention.
본 고안은 도 1에 도시한 바와 같이 차량의 속도변화에 따른 가속도를 감지하는 가속도 센서(100)와, 이 가속도 센서(100)에 의해 감지되는 가속도가 일정레벨 이상시 에어백을 작동시키기 위한 작동신호를 발생시키는 작동신호 발생부(200)와, 이 작동신호 발생부(200)의 작동신호를 인가받아 모터(M)의 작동을 정지시키기 위한 스위칭 신호를 출력하는 콘트롤러(300)와, 이 콘트롤러(300)의 스위칭신호를 인가받아 메인 배터리(400)로부터 모터(M)에 공급되는 전원을 차단하는 릴레이(RY1)(RY2)로 구성된다.The present invention, as shown in Figure 1 acceleration sensor 100 for detecting the acceleration according to the speed change of the vehicle, and the operation signal for operating the airbag when the acceleration detected by the acceleration sensor 100 is a certain level or more The controller 300 for outputting a switching signal for stopping the operation of the motor (M) by receiving the operation signal generator 200 for generating an operation signal of the operation signal generator 200, and the controller ( It is composed of a relay (RY1) (RY2) for receiving a switching signal of 300 to cut off the power supplied to the motor (M) from the main battery (400).
이와 같이 구성된 본 고안의 작용을 설명한다.The operation of the present invention configured as described above will be described.
주행중인 전기자동차의 속도변화를 감지하는 가속도센서(100)에 의해 전기자동차가 충돌사고를 유발하는 것으로 판정되는 경우 작동신호 발생부(200)는 이에 대응하는 작동신호를 생성하여 에어백 시스템에 공급함으로써 운전자를 충돌사고로부터 보호함과 동시에 이 작동신호를 콘트롤러(300)에 공급하게 된다.When it is determined that the electric vehicle causes a collision accident by the acceleration sensor 100 which detects a speed change of the driving electric vehicle, the operation signal generator 200 generates an operation signal corresponding thereto and supplies it to the airbag system. It protects the driver from collision and at the same time supplies this operating signal to the controller 300.
그리하면 콘트롤러(300)는 이 작동신호를 인가받아 전기자동차가 충돌사고를 유발한 것으로 인지하고 모터(M)를 정지시키기 위한 하이 레벨의 스위칭신호를 생성하여 트랜지스터(TR)의 베이스측에 인가한다. 하이 레벨의 스위칭신호를 인가받은 트랜지스터(TR)가 턴온 상태로 절환함으로써, 트랜지스터(TR)의 콜렉터측에 인가중인 전원이 트랜지스터(TR)를 통해서 각각의 릴레이(RY1)(RY2)에 공급되므로 이들 릴레이(RY1)(RY2)가 오프 상태로 절환된다.Then, the controller 300 receives the operation signal, recognizes that the electric vehicle has caused a crash accident, generates a high level switching signal for stopping the motor M, and applies it to the base side of the transistor TR. . Since the transistor TR applied with the high level switching signal is turned on, power applied to the collector side of the transistor TR is supplied to the respective relays RY1 and RY2 through the transistor TR, so that these transistors are turned on. The relays RY1 and RY2 are switched off.
이에 따라 이들 릴레이(RY1)(RY2)를 통해서 모터(M)에 공급되던 메인 배터리(400)의 출력전원이 차단되어 모터(M)가 정지됨으로써, 더 이상의 동력이 생성되는 것을 차단할 수 있는 것이다.Accordingly, the output power of the main battery 400 supplied to the motor M through the relays RY1 and RY2 is cut off and the motor M is stopped, thereby preventing further generation of power.
이상에서와 같이 본 고안은 주행중인 전기자동차의 운전자나 기타 요인으로 인하여 충돌시 에어백 시스템을 동작시켜 운전자를 충돌로부터 보호함과 동시에 에어백 시스템을 작동시킨 작동신호를 이용하여 전기자동차의 동력원인 모터에 공급되는 메인 배터리의 출력전원을 차단함으로써, 전기자동차의 충돌사고시 전기자동차의 안전성을 배가시킬 수 있는 것이다.As described above, the present invention protects the driver from collision by operating the airbag system due to the driver or other factors of the driving electric vehicle and at the same time, by using the operation signal which operates the airbag system to the motor which is the power source of the electric vehicle. By cutting off the output power of the main battery, the safety of the electric vehicle can be doubled in the event of an electric vehicle crash.
즉, 전기자동차의 충돌사고시 전기자동차의 동력원이 전기모터를 정지시켜 전기자동차의 동력이 더이상 공급되지 않도록 함으로써, 충돌시 발생되는 충격을 줄일 수 있을 뿐만 아니라 에어백의 효과를 배가시킬 수 있는 것이다.That is, when the collision of the electric vehicle, the power source of the electric vehicle stops the electric motor so that the power of the electric vehicle is no longer supplied, thereby reducing the impact generated during the collision as well as double the effect of the airbag.
본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 실용신안등록 청구의 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary knowledge in the field to which the present invention belongs without departing from the gist of the present invention claimed in the utility model registration claims. Would be possible.
