Description

Acoustooptic indicator for bicycle

The utility model relates to a kind of indicating device that can send voice, light information, particularly a kind of bicycle acousto-optic indicating device.

China is bicycle user big country.At present, bicycle is only warned with bicycle bell, when turning by bike, as by day, someone one hand takes off making signal, influence traffic safety, and as at night, the someone is being with flash light as throwing light on by bike, because torch light is very dazzling, all make troubles for oneself and others, traffic accident easily takes place.

The purpose of this utility model is for ease of the bicycle traffic safety management, to provide a kind of acousto-optic indicating device of bicycle use.

Composition of the present utility model comprises the housing that can be installed on the handle-bar, power supply, sound light control circuit, luminotron, indicator lamp, loud speaker, it is characterized in that each sound light control circuit parallel connection, comprise: (1), by the wheelpath display switch, luminotron, the wheelpath display circuit that current-limiting resistance is formed, (2), by the switch of warning, the musical film of warning, electronic switch, promote aerotron, the control circuit of warning that loud speaker is formed, (3), by a left side, the right-hand corner switch, a left side, the right-hand corner indicator lamp, about turning voice sheet, promote aerotron, loud speaker form about the sound and light show circuit of turning.

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

Fig. 1 is the utility model electrical schematic diagram.

Fig. 2 is the utility model profile scheme drawing.

As shown in Figure 1, be connected to 6 volts of direct supplys in the circuit, sound light control circuit in parallel: wheelpath display circuit---wheelpath display switch K1, two groups of luminotron LED1-LED6, LED7-LED12, current-limiting resistance R1, control circuit---the K switch 2 of warning of warning, musical film IC1 warns, by diode D1, D2, resistance R 2, R3, the electronic switch that aerotron Q1 forms, promote aerotron Q2, loud speaker Y, about sound and light show circuit---the turnon left K switch 3 of turning, turnon left indicator lamp I1, right-hand corner K switch 4, right-hand corner indicator lamp I2, about turning voice sheet IC2, promote aerotron Q3, loud speaker Y.The D1 of electronic switch, D2 anode are connected with indicator lamp I2, I1 anode respectively, and negative terminal is connected to R2 one end, another termination of R2 Q1 base stage, Q1 emitter sound taking alarm musical film negative terminal, collecting electrode power connection negative terminal, R3 one termination R2, other end power connection negative terminal.

The utility model control process is as follows:

Can connect K1 night by bike, and LED1-LED12 is luminous for the luminotron group, the display line wheel paths.When meeting emergency situation, can connect K2, because chimes of doom music sheet IC1 trigger electrode is connected on power positive end, the IC1 ground wire connects the aerotron Q1 emitter of electronic switch, R2, R3 connects provides biasing to Q1, the Q1 conducting promotes IC1 and aerotron Q2, makes IC1, Q2 obtain enough warning outgoing currents, promotes loud speaker Y and sends loud and clear alarm sound music.During turnon left, connect K3, I1 is bright for the turnon left indicator lamp, trigger current is provided for simultaneously voice ic chip 2, the IC2 outgoing current is given the Q3 base stage, promotes loud speaker Y and sends the cue of turnon left language, equally, connect K4 during right-hand corner, I2 is bright for the right-hand corner indicator lamp, and loud speaker Y sends right-hand rotation voice suggestion signal.The effect of the electronic switch of being made up of D1, D2, R2, R3, Q1 is, utilize the unilateral conductivity of diode D1, D2, when K3 or K4 connection, provide reverse bias by D1 or D2, R2 to Q1, Q1 is ended, cut off the negative power supply of IC1 and Q2 emitter, in case alarm switch K2 is when opening, turning voice suggestion sound about chimes of doom disturbs.

As shown in Figure 2, the utility model shell 1 can be fixed on the handle-bar 2, and K1-K4 is 4 switches among the figure, and LED1-LED12 is the luminotron group, and I1, I2 are left and right sides rear blinker, and Y is a loud speaker.

The IC1 model is 9562 among the embodiment, the IC2 model is 56026, and Q1 is the C8550 aerotron, and Q2, Q3 are the C8050 aerotron, D1, D2 are the IN4148 diode, R1 is 30-60 ohm/1W carbon film or metal film resistor, and R2, R3 are respectively 1K ohm/1/8W carbon resister, and I1, I2 are the 0.1A/6.3V indicator lamp, LED1-LED12 is a light-emitting diode, Y is 0.25W/8 ohm loud speaker, and K1-K4 is 1 * 2 toggle switch, and power supply is made up of 4 R6P dry storage batterys.

The utility model compact conformation, volume is little, and use all very convenient day and night, and the sound of warning is melodious, guarantees traffic safety, reduces traffic accident.
