Abstract
The invention discloses a steering indicator of a tricycle, and relates to the technical field of steering voice prompt for a vehicle. The steering indicator comprises a music integrated circuit IC1 and a time-base circuit IC2 which are connected together, a self-excited multi-vibrator formed by the time-base circuit IC2, a resistor R2, a potentiometer W, a capacitor C1 and the like, and an audio frequency oscillator and a steering lamp circuit which are connected with the time-base circuit IC2. The steering indicator has the beneficial effects that when a steering lamp of the tricycle is on, music prompt is given out at the same time, thus reducing crash events.
Description
Technical field
The present invention relates to a kind of Vehicular turn auditory tone cues device, specifically is that a kind of three-wheel vehicle turns to the news Chinese percussion instrument.
Background technology
At present, though the three-wheel vehicle on the market all has steering indicating light, do not have the auditory tone cues of turning to device.Night, other people can be clearly seen that the flicker of steering indicating light, can get ready in advance.But just do not see the flicker of Chu steering indicating light, the generation that easily cause the accident because sunray is stronger daytime.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the invention provides a kind of three-wheel vehicle and turn to the news Chinese percussion instrument, when turning to, sends three-wheel vehicle voice prompt, the generation of prevention car accident.
The present invention realizes with following technical scheme: a kind of three-wheel vehicle turns to the news Chinese percussion instrument, comprise music integrated circuit IC1, with music integrated circuit IC1 bonded assembly time base circuit IC2, the free running multivibrator that time base circuit IC2 and resistance R 2, potential device W and cond C1 etc. constitute, with time base circuit IC2 bonded assembly audio frequency oscillator, with time base circuit IC2 bonded assembly steering indicating light circuit.
The invention has the beneficial effects as follows: when the steering indicating light of three-wheel vehicle lights, have music tip simultaneously, reduced the incidence of bumper car incident.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is schematic circuit diagram of the present invention.
The specific embodiment
As shown in drawings, three-wheel vehicle turns to the news Chinese percussion instrument, comprise music integrated circuit IC1, with music integrated circuit IC1 bonded assembly time base circuit IC2, the free running multivibrator that time base circuit IC2 and resistance R 2, potential device W and cond C1 etc. constitute, with time base circuit IC2 bonded assembly audio frequency oscillator, with time base circuit IC2 bonded assembly steering indicating light circuit.
In the present embodiment, music integrated circuit IC1 adopts Music Clip CW9561; Time base circuit IC2 adopts 555 time base circuits.Parallel capacitance C1,2 pin and 6 pin are connected respectively to the end of potential device W between 1 pin of time base circuit IC2 and 2 pin, and the other end of W is connected to 7 pin of IC2, shunt resistance R2 between 7 pin and 8 pin, and 8 pin are connected with 4 pin; Foregoing circuit has constituted free running multivibrator.Audio frequency oscillator comprises resistance R 3, unijunction transistor BG2 and piezoelectricity singing piece Y2; Resistance R 3, unijunction transistor BG2 and piezoelectricity singing piece Y2 constitute a C/LOOP, and the base stage of BG2 connects the common port that is Y2 and R3, and the two poles of the earth in addition of BG2 and 1,3 pin of 555 time base circuits are connected.The steering indicating light circuit comprises coupled twin switch K2, left steering lamp DL, right steering lamp DR, the end of K2 is connected with 4 pin of 555 time base circuits, the other end is connected the midway location of left steering lamp DL and right steering lamp DR, and the other end of left steering lamp DL and right steering lamp DR is connected with 3 pin of 555 time base circuits respectively.
Concrete mode of operation: when the 3 pin output high level of 555 time base circuits, by the audio frequency oscillator work that resistance R 3, unijunction transistor BG2 and piezoelectricity singing piece Y2 form, piezo Y2 pronounces, to other people prompting of sounding.When 3 pin output low levels, left steering lamp DL and right steering lamp DR are luminous because of obtaining voltage.When coupled twin switch K2 was in the center at ordinary times, 555 time base circuits and DL, DR and power supply E disconnected, and circuit does not send sound and light signal.And when K2 is in a left side or right position, all can connect power supply and steering indicating light of IC2, make circuit alternately send sound and light signal, to cause other vehicles and pedestrian's attention.
This circuit also can be used as illumination, electronic bell etc. except that there being the turning flash news to ring the function.The K1 that closes a switch in the circuit can light illuminating lamp DZ; Press the button AN, music integrated circuit IC1 work promptly can be used as electronic bell.
