The car steering wheel deflection angle display is characterized in that the laser needle is fixedly arranged on an output shaft on the tail end of a steering device and connected with a laser generator to transmit single-beam laser; the position where the laser needle is fixedly arranged meets the requirements that when the deflection angle of a car steering wheel is zero, i.e. a car goes straight, the laser needle is pointed to the direction of travel, the transmitted single-beam laser illuminates the (n+1)/2 photosensitive diode in the middle position of the semicircular base, the photosensitive diode is conducted by illumination, and the LED light connected with the photosensitive diode on the display is lightened; and when the laser needle turns left or right along with the output shaft, the single-beam laser transmitted by the laser needle illuminates the left or the right photosensitive diode with the corresponding angle, the LED light corresponding to the photosensitive diode on the display is lightened, and the left steering angle or the right steering angle of the steering wheel is displayed.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of motor turning wheel angle of inclination display instrument.
Background technology
Chaufeur comes the travel direction of Control of Automobile through the steering dish, because angle and motor turning wheel angle that bearing circle rotates are inconsistent, the travel direction of automobile is that the rotational angle and the number of turns of steering dish are confirmed by rule of thumb by chaufeur basically.When automobile went on narrow road or get into the parking stall reversing, the angle of inclination of wheel flutter had deviation slightly, and automobile will depart from conditional travel direction, caused traffic accident.Motor turning wheel angle of inclination display instrument can show motor turning wheel deflection angle in real time, helps chaufeur and takes correct operation measure, also guarantees that for chaufeur wheel is in the normal position visual indication is provided when parking.
Summary of the invention
To an existing difficult problem, the purpose of the utility model provides a kind of motor turning wheel angle of inclination display instrument, can show motor turning wheel deflection angle in real time, is beneficial to chaufeur and takes correct operation measure.
The utility model solves the technical scheme that its technical matters adopted: motor turning wheel angle of inclination display instrument; Comprise that mainly (n among this paper is odd number and is at least 7 for laser needle, a n photodiode; As follows), half circular base, seal closure, power supply, switch, a n LED lamp, display instrument; Be characterized in: said laser needle is fixed on to be connected also on the terminal output shaft of deflector, with laser generator can launch single beam laser; Satisfy its fixed position, is zero to be automobile when keeping straight on when motor turning wheel angle of inclination, and laser needle points to direction of traffic; The single beam laser of launching can shine on (n+1)/2 photodiode of half circular base midway location; The angle of laser needle left-hand rotation or right-hand rotation is all less than 90 °, and the angle of steered wheel left-hand rotation or right-hand rotation is also all less than 90 °, i.e. the angle of the angle of laser needle deflection and steered wheel deflection forms one to one and concerns; Said half circular base is fixed on the seal closure fwd inside face, at inboard stationary arrangement n photodiode of half circular base; Said seal closure is provided with fixed orifice and axis hole, and the diameter of terminal output shaft of deflector and axis hole is adaptive and pass from axis hole, can seal closure be fixed on the car chassis through fixed orifice, and laser needle, half circular base are all in seal closure; In the said n photodiode; Each all passes through lead and connects back parallelly connected with a LED lamp; The upper end lead is received the positive pole of power supply through switch; The lower end lead is received the negative pole of power supply, and n LED lamp semicircular in shape is fixedly installed on the dish of display instrument and is corresponding one by one with motor turning wheel angle of inclination.
During use; Display instrument is fixed in the operator's compartment; Open laser generator, Closing Switch gets final product, if not deflection of automobile steering roller; The single beam laser that laser needle is launched will shine on (n+1)/2 photodiode of half circular base midway location, and this photodiode is lighted (the n+1)/2LED lamp that is attached thereto on the display instrument because of the illumination conducting; When the terminal output shaft rotating band of deflector electrical automobile wheel flutter left or right avertence when changeing; Laser needle on it can be along with left or turn right moving; The single beam laser that laser needle is launched will shine the photodiode of a left side or right corresponding angle, light cooresponding with it LED lamp on the display instrument.Do not think the time spent, close laser generator, cut-off switch gets final product, and also can remove easily.
The beneficial effect of the utility model is, and is simple in structure, easy for installation, helps safe driving.
