전자제어식 가속페달장치{Device for electronic accelerator pedal}Electronically controlled accelerator pedal device {Device for electronic accelerator pedal}

본 발명은 차량의 가속페달장치에 관한 것으로, 특히 가속페달에 인가된 답력에 따라 연료 분사량을 전자제어하는 전자제어식 가속페달장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accelerator pedal apparatus of a vehicle, and more particularly, to an electronically controlled accelerator pedal apparatus for electronically controlling a fuel injection amount according to a step force applied to an accelerator pedal.

일반적으로 자동차의 가속페달장치는 페달 스트로크에 따라 연료 분사량을 제어하게 되며, 크게 기계식과 전자제어식으로 구분된다.In general, the accelerator pedal of the vehicle controls the fuel injection amount according to the pedal stroke, and is largely divided into mechanical and electronically controlled.

기계식 가속페달장치는 케이블 타입과 로드 타입이 있다.Mechanical accelerator pedals are available in both cable and rod types.

전자제어식 가속페달장치는 운전자가 가속페달을 밟으면 가속페달에 구비된 센서가 신호를 감지하여 제어유니트에 의해 연료량을 조절하도록 하고 있다.The electronically controlled accelerator pedal device controls the amount of fuel by the control unit by detecting a signal when the driver presses the accelerator pedal.

도 1은 일반적인 전자제어식 가속페달장치를 보여주는 도면이다.1 is a view showing a general electronically controlled accelerator pedal device.

이하, 일반적인 전자제어식 가속페달장치를 구체적으로 살펴보면 다음과 같다.Hereinafter, a general electronically controlled accelerator pedal device will be described in detail.

도 1을 참고하면, 풋플레이트(10)와 피봇 스핀들(11)에 의해 힌지 체결된 하부플레이트(20)가 구비된다.Referring to FIG. 1, the lower plate 20 hinged by the foot plate 10 and the pivot spindle 11 is provided.

풋플레이트(10)의 하부에는 회동 가능하게 힌지 체결된 롤러조립체(30)가 구비되며, 이 롤러조립체(30)의 하단에는 자유 회동하는 롤러(31)가 구비된다.The lower portion of the foot plate 10 is provided with a rotatable hinged roller assembly 30, the lower end of the roller assembly 30 is provided with a roller 31 for free rotation.

풋플레이트(10)의 하부에는 롤러조립체(30)의 회전 동작을 감지하여 신호를 출력하는 센서부(40)가 구비된다. 이 센서부(40)는 센서튜브(41)에 의해 미도시된 제어유니트로 연결되어 풋플레이트(10)의 답력에 따라 제어유니트는 엔진 연료량을조절하게 된다.The lower portion of the foot plate 10 is provided with a sensor unit 40 for outputting a signal by detecting the rotational movement of the roller assembly 30. The sensor unit 40 is connected to the control unit (not shown) by the sensor tube 41 so that the control unit adjusts the engine fuel amount according to the foot force of the foot plate 10.

풋플레이트(10)와 롤러조립체(30)에는 리턴스프링(50)이 구비되며, 이 리턴스프링(50)의 양 단부는 각각 풋플레이트(10)와 롤러조립체(30)에 각각 고정된다.The foot plate 10 and the roller assembly 30 are provided with a return spring 50, and both ends of the return spring 50 are fixed to the foot plate 10 and the roller assembly 30, respectively.

리턴스프링(50)은 운전자가 풋플레이트(10)를 조작하는 경우에 답력을 제공하게 된다.The return spring 50 provides a response when the driver manipulates the foot plate 10.

이와 같이 구성된 종래의 전자제어식 가속페달장치는 운전자가 풋플레이트(10)를 조작하게 되면, 센서부(40)가 신호를 감지하여 제어유니트로 출력하며, 제어유니트는 엔진 연료량을 조절하게 된다.In the conventional electronically controlled accelerator pedal device configured as described above, when the driver operates the foot plate 10, the sensor unit 40 detects a signal and outputs the signal to the control unit, and the control unit adjusts the engine fuel amount.

이때, 운전자가 풋플레이트(10)를 조작하기 위해 필요한 답력은 풋플레이트(10)에 구비된 리턴스프링(50)의 복원력에 의해 결정된다.At this time, the driver's effort required for manipulating the foot plate 10 is determined by the restoring force of the return spring 50 provided in the foot plate 10.

기계식 가속페달장치에서는 리턴스프링이 답력에 미치는 영향은 크지 않으나, 전자제어식 가속페달장치에서 리턴스프링만이 답력을 결정하게 된다.In the mechanical accelerator pedal system, the return spring does not have a significant effect on the horse power, but in the electronically controlled accelerator pedal, only the return spring determines the horsepower.

그러나, 종래에 전자제어식 가속페달장치는 리턴스프링의 탄성력이 일률적으로 동일하게 설정되어 나오게 되므로 운전자의 조건에 따라 풋플레이트의 조작 답력을 변경할 수가 없으므로 많은 불편함이 발생하게 된다.However, in the conventional electronically controlled accelerator pedal device, since the elastic force of the return spring is uniformly set, the operation effort of the foot plate cannot be changed according to the driver's condition, which causes a lot of inconvenience.

본 발명은 상기의 결점을 해소하기 위한 것으로, 가속페달에 인가된 답력에 따라 연료 분사량을 전자제어하는 전자제어식 가속페달장치에 있어 운전자의 편의에 따라 풋플레이트의 조작 답력의 설정을 변경할 수 있는 전자제어식 가속페달장치를 제공하고자 한다.The present invention is to solve the above-mentioned shortcomings, the electronically controlled accelerator pedal for electronically controlling the fuel injection amount in accordance with the response force applied to the accelerator pedal, the electronic that can change the setting of the operation effort of the foot plate according to the driver's convenience To provide a controlled accelerator pedal device.

이러한 본 발명은 풋플레이트 답력을 감지하기 위한 센서부와, 이 센서부의 신호에 따라 연료량을 조절하는 제어유니트로 구성된 차량의 전자식 가속페달장치에 있어서, 최소한 두개 이상의 걸림부가 구비되어 상기 풋플레이트의 하부에 구비된 지지브라켓과; 걸림핀이 구비되어 상기 지지브라켓에 힌지 체결된 롤러조립체와; 각 단부가 상기 걸림부와 상기 걸림핀에 걸려 고정된 탄성체로써 달성된다.The present invention is an electronic accelerator pedal apparatus of a vehicle composed of a sensor unit for detecting a foot plate stepping force, and a control unit for adjusting the fuel amount in accordance with the signal of the sensor unit, at least two engaging portions are provided in the lower portion of the foot plate Support brackets provided in; A roller assembly provided with a locking pin and hinged to the support bracket; Each end is achieved by an elastic body fixed to the locking portion and the locking pin.

상기 풋플레이트(100)는 차체프레임에 고정 설치된 하부플레이트(200)와 피봇 스핀들(101)에 의해 힌지 체결된다.The foot plate 100 is hinged by the lower plate 200 fixed to the vehicle body frame and the pivot spindle 101.

상기 롤러조립체(130)의 하단에는 하부플레이트(200)를 따라 자유 회동하는 롤러(132)가 구비된다.The lower end of the roller assembly 130 is provided with a roller 132 for free rotation along the lower plate 200.

풋플레이트(100)의 하부에 구비된 지지브라켓(120)은 바람직하게는 원호 형상을 가지며, 답력 설정 범위에 따라 다수의 걸림부(121)가 형성된다.The support bracket 120 provided in the lower portion of the foot plate 100 preferably has an arc shape, and a plurality of engaging portions 121 are formed according to the setting range of the stepping force.

상기 탄성체는 축회전에 의해 탄성력을 갖는 힌지스프링(140)으로 제공될 수가 있으며, 힌지스프링(140)의 양 단부는 각각 롤러조립체(130)의 걸림핀(131)과, 지지브라켓(120)의 걸림부(121)에 걸려 고정된다.The elastic body may be provided to the hinge spring 140 having an elastic force by the axial rotation, the both ends of the hinge spring 140, respectively, the engaging pin 131 of the roller assembly 130 and the support bracket 120 It is caught and fixed to the locking portion 121.

이와 같이 구성된 본 발명의 전자제어식 가속페달장치는 종래기술에서 상술한 바와 같이 동일한 작용에 의해 풋플레이트(100)의 조작에 따라 가속페달에 작용된 답력이 센서부(110)를 통하여 제어유니트에 전달되어 엔진 연료량을 조절하게 된다.In the electronically controlled accelerator pedal apparatus of the present invention configured as described above, the pedaling force acting on the accelerator pedal according to the operation of the foot plate 100 is transmitted to the control unit through the sensor unit 110 as described above in the related art. The engine fuel amount is adjusted.

이때, 지지브라켓(120)에 형성된 다수의 걸림부(121) 중에 하나에 걸려 고정된 힌지스프링(120)의 단부의 위치를 변경함으로써 운전자는 풋플레이트(100)를 조작하는데 필요한 답력의 정도를 조정할 수가 있다.At this time, by changing the position of the end of the hinge spring 120 is fixed to one of the plurality of engaging portions 121 formed in the support bracket 120, the driver adjusts the degree of the step required to operate the foot plate 100 There is a number.
