Embodiment

Below in conjunction with accompanying drawing, and other technical characteristic above-mentioned to the utility model and advantage are carried out clearly and completely Description, it is clear that described embodiment is only section Example of the present utility model, rather than whole embodiments.

Reference picture 1, the utility model provide a kind of shared bicycle and overturn identification warning device, are arranged on shared bicycle In cushion 1.

Reference picture 2, the shared bicycle, which overturns identification warning device, includes gravity sensor 100, control circuit 200, first Single-shot trigger circuit 310, the second single-shot trigger circuit 320, the first sound circuit 410 and the second sound circuit 420；Tool Body is that gravity sensor 100 is located at the rearward end of cushion 1 and connects control circuit 200, is turned over to the left for detecting shared bicycle Or turn over to the right；First single-shot trigger circuit 310 connects the sound circuit 410 of control circuit 200 and first respectively, and altogether Enjoy and the sounding alarm of the first sound circuit 410 is controlled when bicycle turns over to the left；Second single-shot trigger circuit 320 connects control electricity respectively The sound circuit 420 of road 200 and second, and the sounding alarm of the second sound circuit 420 is controlled when shared bicycle turns over to the right；Its In, the alarm terminal BL of the first sound circuit 410 and the second sound circuit 420 is respectively arranged on right-hand end and the left side of cushion 1 End.

In the present embodiment, why gravity sensor 100 is arranged in cushion 1, is because shared bicycle is when overturning Meeting bad student's significant shock, and gravity sensor 100 is relatively accurate device, is easily damaged when being impacted by larger hardness. Therefore, it is arranged in cushion 1, solves this problem well.In addition, for devices such as alarm terminal BL, have also been made Identical processing.

In fact, when shared bicycle overturn when, exist and turn over or turn over to the right two kinds of situations to the left, no matter which kind of situation, Alarm terminal BL is arranged on surface when shared bicycle overturns, pedestrian can be prompted to the full extent.Therefore, will alarm Terminal BL is arranged on the both side ends of cushion 1 so that when shared bicycle overturns, alarm terminal BL can be towards surface.In this base On plinth, it can to the left be turned over by the shared bicycle of the acquisition of gravity sensor 100 and still turned over to the right, when shared bicycle turns over to the left, led to The control of control circuit 200 is crossed to be alarmed positioned at the alarm terminal BL of the right-hand end of cushion 1, when shared bicycle turns over to the right, Alarmed by the control of control circuit 200 positioned at the alarm terminal BL of the left end of cushion 1.

More specifically, reference picture 3, the first single-shot trigger circuit 310 include NE555p chips, and the 4th of NE555p chips the Pin and the 8th pin are all connected with the positive pole of battery, and the first pin and the 5th pin of NE555p chips connect battery respectively Negative pole, the output end of the second pin connection control circuit 200 of NE555p chips, the 3rd pin connection the of NE555p chips One sound circuit 410.In addition, the positive pole of the 4th pin of NE555p chips and the equal gate-controlled switch connection battery of the 8th pin, Gate-controlled switch is controlled by control circuit 200.As alarm terminal BL, the first sound circuit 410 include speech chip, triode with And alarm terminal BL, the 3rd pin of the input connection NE555p chips of speech chip, the output end connection three of speech chip The base stage of pole pipe, the colelctor electrode of triode connect the positive pole of battery, the emitter stage connection battery of triode by loudspeaker Negative pole.

Accordingly, the second single-shot trigger circuit 320 includes NE555p chips, the 4th pin of NE555p chips and the 8th Pin is all connected with the positive pole of battery, and the first pin and the 5th pin of NE555p chips connect the negative pole of battery respectively, The output end of the second pin connection control circuit 200 of NE555p chips, the 3rd pin of NE555p chips connect the first voice Circuit 410.In addition, the positive pole of the 4th pin of NE555p chips and the equal gate-controlled switch connection battery of the 8th pin, controllable to open Pass is controlled by control circuit 200.As alarm terminal BL, the second sound circuit 420 includes speech chip, triode and alarm Terminal BL, the 3rd pin of the input connection NE555p chips of speech chip, the output end connecting triode of speech chip Base stage, the colelctor electrode of triode connect the positive pole of battery, the negative pole of the emitter stage connection battery of triode by loudspeaker.

Operation principle therein is that, when shared bicycle is overturning, gravity sensor 100 produces induced signal, can make Single-shot trigger circuit switchs to transient state by stable state, and its 3rd pin output high level makes the output end of speech chip export high electricity It is flat, turn-on transistor, and then make loudspeaker sounding alarm.

Particular embodiments described above, the purpose of this utility model, technical scheme and beneficial effect are carried out to enter one The detailed description of step, it will be appreciated that the foregoing is only specific embodiment of the utility model, be not used to limit this reality With new protection domain.Particularly point out, to those skilled in the art, it is all the spirit and principles of the utility model it It is interior, any modification, equivalent substitution and improvements done etc., it should be included within the scope of protection of the utility model.
