Steering angle displayer for handle with reset function}

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

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.

Steering conditions of the front wheels are usually predicted by the sense of operation through the steering wheel and the direction of travel of the vehicle, but this is a good driver, and beginners do not know the current state of the front wheels at the initial stage of departure after parking and have an accident. In particular, when the driver attempts to escape by using a narrow space between the front and rear vehicles, steering is possible without contact accident if the driver can recognize the steering condition of the front wheel from the driver's seat. .

Conventional steering angle display method is to measure the rotation of the steering shaft connected to the steering wheel by 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.

Another method using gravity action has been proposed. This method restricts the movement of gravity-bearing beads or weights according to a certain trajectory, and allows the plate to be interlocked with the movement of the center of the beads 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.

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.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a steering wheel steering angle indicator having a reset function which can easily perform zero adjustment even when the indicator hand is out of the reference line.

In addition, another object of the present invention is to improve the configuration of the gear to provide a steering wheel steering angle indicator with a reset function to prevent the departure of the gear even when used for a long time with accurate operation.
