Description
본 발명은 자동차나 모터보트의 운전 중 휠의 방향 또는 방향키를 핸들의 조작과 더불어 지시침이 조향각을 표시하는 조향각 표시기에 관한 것으로, 더욱 상세하게는 기어의 유격에 의해 지시침이 기준선을 벗어났을 때 영점 조정을 용이하게 할 수 있는 리셋 기능이 있는 핸들 조향각 표시기에 관한 것이다.The present invention relates to a steering angle indicator in which the indicator hand indicates a steering angle in addition to the steering wheel operation of a wheel or a direction key while driving an automobile or a motor boat. More specifically, the indicator hand may be out of the reference line due to the play of the gear. Handle steering angle indicator with reset function to facilitate zero adjustment when
일반적으로 차량의 핸들은 그 주행 방향을 제어하는 기구로 필수적인 장치이며, 이것은 운전자가 의도하는 바대로 회동 조작되었을 때에 앞 차륜을 연동시켜 조향 되게 하는 구성으로 되어 있다. 일반적으로 차량의 핸들은 승용차의 경우에 좌우로 1.5회전, 버스 트럭 등의 상용차는 2.5회전에 앞 차륜이 최대의 조향 상태로 되게 하고 있다. In general, the steering wheel of a vehicle is an essential device as a mechanism for controlling the driving direction, which is configured to steer by interlocking the front wheels when the driver rotates as intended. In general, the steering wheel of the vehicle is 1.5 turns left and right in the case of a passenger car, and the commercial vehicle, such as a bus truck, is made 2.5 turns in the front wheel, so that the front wheel is in the maximum steering state.
앞바퀴의 조향 상태는 대개 핸들을 통한 조작 감각과 차량의 진행 방향을 감지하여 예측함이 일반적이지만 이것은 능숙한 운전자에 해당하고, 운전 초심자는 주차 후의 출발 초기 단계에서 앞차륜의 현재 상태를 예측치 못하여 사고를 유발하는 일이 있고, 특히 앞뒤 차량 사이에서 좁은 공간을 이용하여 빠져나오려 하는 때의 전 후진 조향은 운전자가 운전석에서 앞 차륜의 조향 상태를 알아볼 수 있으면 접촉 사고 없이 조향이 가능하여 대단히 편리하게 된다.The steering condition of the front wheels is usually estimated by sensing the steering feeling and the direction of the vehicle's driving, but this is a good driver, and the beginners do not predict the current condition of the front wheels at the initial stage of departure after parking and cause accidents. In particular, when the driver attempts to escape by using a narrow space between the front and rear vehicles, the driver can recognize the steering state of the front wheel in the driver's seat and can be steered without contact accident.
종래의 조향각 표시 방법은 핸들과 연결된 스티어링 축의 회동을 센서로 측정하여 이를 연산한 다음 인스트루먼트 패널 등에 배치된 디스플레이를 통하여 차륜의 조향각을 그림 등으로 표시하여 주는 것이 있으나 이것은 차량의 제조 공정에서 미리 조립되어야 하고 기존 차량에는 적용할 수 없는 단점이 있어서 실용화하기가 어려운 문제가 있다.Conventional steering angle display method is to measure the rotation of the steering shaft connected to the steering wheel using a sensor to calculate it and then display the steering angle of the wheel as a picture through a display disposed on the instrument panel, etc. This must be assembled in advance in the manufacturing process of the vehicle And there is a problem that can not be applied to the existing vehicle is difficult to be practical.
다른 방법으로 중력 작용을 이용한 방법이 제안되어 있다. 이 방식은 중력을 받는 구슬이나 중량체가 일정의 궤적에 따라 움직일 수 있게 제한하여 놓고, 핸들의 회동 시에 야기되는 상기 구슬이나 중량체의 중심 이동에 수반하여 판체가 연동되게 하고, 상기 구슬이나 중량체에 의한 판체의 이동이 소형의 감속기어를 경유하여 방향 표시판을 연동시켜서 그 판 면에 열린 구멍을 통해 상기 판체 상면에 인쇄된 각도 수치로 앞 차륜의 조향 상태가 표시되게 하고 있다.Another method using gravity action has been proposed. This method restricts the movement of gravity bead or weight body according to a certain trajectory, and allows the plate to be interlocked with the movement of the center of the bead or weight caused by the rotation of the handle. The movement of the plate body by the sieve interlocks the direction display plate via the small reduction gear, and the steering state of the front wheel is displayed by the angle value printed on the upper surface of the plate body through the opening in the plate surface.
그러나, 이러한 종래의 조향각 표시기는 기어방식을 사용하기 때문에 핸들조작시 기어의 유격에 의해 지시침이 중앙 기준선에서 좌측 또는 우측으로 벗어나는 경우가 종종 발생한다. 따라서 지시침의 영점 조정을 위하여 조향각 표시기를 차량에서 떼어낸 후 영점을 조정하여 수시로 다시 부착해야하는 번거로움이 있다.However, since such a conventional steering angle indicator uses a gear type, the indicator hand often deviates from the center reference line to the left or the right by the play of the gear during the steering wheel operation. Therefore, it is troublesome to remove the steering angle indicator from the vehicle to adjust the zero point of the indicator hand and to reattach it from time to time.
