Most of battery vehicles do not have the Brake lamp working procedure that camera motor-car is the same on the market, potential safety hazard when this has just formed fast running, so stop lamp time-delay quenching control device is installed in battery vehicle, can remind vehicle below to note, has very large Practical significance for battery vehicle traffic safety.The utility model is after battery vehicle installs stop lamp time-delay quenching control device additional, can allow battery vehicle Brake lamp as car Brake lamp, after braking system resets, time delay Brake lamp in 1～2 second just can extinguish again, for reminding the vehicle after closelying follow to note, can effectively avoid vehicle rear-end collision accident to occur, increase battery vehicle traffic safety.
Below describe the correlation technique content that stop lamp delayed lights-out control device for battery car described in the utility model relates in implementation process in detail.
Utility model content
Goal of the invention and beneficial effect: most of battery vehicles do not have the Brake lamp working procedure that camera motor-car is the same on the market, potential safety hazard when this has just formed fast running, so stop lamp time-delay quenching control device is installed in battery vehicle, can remind vehicle below to note, for battery vehicle traffic safety, have very large Practical significance.The utility model is after battery vehicle installs stop lamp time-delay quenching control device additional, can allow battery vehicle Brake lamp as car Brake lamp, after braking system resets, time delay Brake lamp in 1～2 second just can extinguish again, for reminding the vehicle after closelying follow to note, can effectively avoid vehicle rear-end collision accident to occur, increase battery vehicle traffic safety.
Circuit working principle: when battery vehicle normally travels, because the brake line of brushless motor controller is exported about 5V high level, NPN type triode VT1 is all the time in conducting state, at this moment on electrochemical capacitor C1, substantially there is no direct voltage, enhancement mode N channel field-effect pipe VT2 can not get bias voltage and ends, and the upper no-voltage of Brake lamp HL1～HL2 is not worked; When battery vehicle is when braking, the high level of brake line output becomes low level, make NPN type triode VT1 cut-off, when electrochemical capacitor C1 passes through resistance R 2 quick charge, give enhancement mode N channel field-effect pipe VT2 bias voltage, make enhancement mode N channel field-effect pipe VT2 conducting, Brake lamp HL1～HL2 has electric current to flow through to be lit.After take-off the brake handle, direct voltage on electrochemical capacitor C1 can not discharge rapidly, enhancement mode N channel field-effect pipe VT2 just continues to keep conducting state, along with electrochemical capacitor C1 discharges by discharge resistance R3, that is: the direct voltage on electrochemical capacitor C1 is through discharging for 1～2 second, direct voltage on electrochemical capacitor C1 is during lower than enhancement mode N channel field-effect pipe VT2 conducting valve threshold voltage, enhancement mode N channel field-effect pipe VT2 cut-off, after Brake lamp HL1～HL2 being lighted maintained for 1～2 second, extinguish, then NPN type triode VT1 recovers again conducting, enhancement mode N channel field-effect pipe VT2 ends again, make Brake lamp HL1～HL2 again in extinguishing state, thereby reach the object of battery vehicle braking indication.
The turn on delay time of enhancement mode N channel field-effect pipe VT2 is determined by 2 factors: the one, and the size of electrochemical capacitor C1 discharge loop discharge resistance R3 resistance; The 2nd, the amount of capacity of electrochemical capacitor C1.
