Description

A kind of brake annunciator

(1) technical field

The utility model relates to by time-delay, vibration, the brake annunciator that signal feedback three partial circuits are formed.

(2) technical background

Braking warning is the indispensable critical function of vehicle, after the vehicle brake that travels slows down, the red light of afterbody can blast warn back vehicle and pedestrian to note, but in the frequent traffic accident of knocking into the back, we find that the caution of this kind afterbody red light blast obviously is not enough to remind back vehicle to note.

(3) summary of the invention

The purpose of this utility model provides a kind of simple in structure, is easy to bonded assembly brake annunciator, can overcome the not enough problem of brake caution in the past.

Solution is: by a socket with stoplight stop lamp, Cornering Lamp, BK Brake Switch, flasher relay, control circuit connects into a complete circuit, connect by time delay circuit by BK Brake Switch between stoplight stop lamp and Cornering Lamp, the control circuit that oscillating circuit and reactive circuit are formed, flasher relay is connected across between power positive end and the turning switch.When BK Brake Switch is moved, start by time delay circuit, the control circuit that oscillating circuit and reactive circuit are formed, when making stoplight stop lamp bright, the Cornering Lamp stroboscopic.Time delay circuit can be made of the RC circuit, also can be made of quartz crystal; Oscillating circuit can be made of electric capacity or inductor oscillating, also can take crystal oscillation circuit.Socket DJ has four inserted sheets, the one end respectively with BK Brake Switch K1, stoplight stop lamp L3, Cornering Lamp L1, L2, L4 and L5 link to each other; The socket DJ inserted sheet DJ-1 other end and three branch roads, be respectively, diode VD1, the anode of VD2, the drain electrode of field effect transistor is joined.The negative pole of diode VD1 by resistance R 1 respectively with resistance R 2, R3, R5,4,8 pin of ic chip, the anode of zener diode VD7 and capacitor C 1 connects.Socket DJ inserted sheet DJ-2 and VD4, the negative pole of VD6 joins, the VD6 positive pole respectively with field effect transistor VT4 emitter, capacitor C 5, resistance R 9, resistance R 7, capacitor C 4 and diode VD5 are anodal to be connected; The VD4 positive pole respectively with diode VD3 negative pole, 2 pin of ic chip, capacitor C 2 and resistance R 2 links to each other, socket DJ inserted sheet DJ-3 and diode VD3 positive pole, the VD5 negative pole connects, the VD5 positive pole links to each other with the VD6 positive pole, the VD3 negative pole links to each other with the VD4 negative pole; Socket DJ inserted sheet DJ-4 and aerotron VT1, the VT2 emitter, diode VD7 positive pole, 1 pin of capacitor C 1 negative pole ic chip, capacitor C 2, the C3 negative pole links to each other; 3 of resistance R 3 and capacitor C insert integrated package 6,7 pin, and 3 pin of ic chip link to each other with the VT1 base stage through resistance R 4, VT1 collecting electrode and R5, and the VT2 base stage connects; The VT2 collecting electrode is connected with the VT3 base stage.The collecting electrode of VT3, emitter respectively with resistance R 8, R9 connects, R8, the other end of R9 respectively with R6, the series arm of R7, C4 the two poles of the earth, VT4 collecting electrode, emitter parallel connection.When BK Brake Switch K1 moves, 3 pin of IC output high potential, the VT1 conducting, VT2 ends, VT3, VT4, the oscillating circuit of compositions such as C5 and load is started working, Cornering Lamp L1, L2, L4 and L5 are glittering.When BK Brake Switch K1 moved, because C2, the C3 both end voltage can not be suddenlyd change, and can only pass through resistance R 2, and R3 is to its charging.When the 6 pin current potentials of IC rise to power line voltage 2/3 the time, 3 pin of IC become active potential by high potential, VT1 ends, the VT2 conducting, the base stage of VT3 is by short circuit, oscillating circuit quits work, left and right sides Cornering Lamp L1, L2, L4 and L5 stop dodging.Turn sign passes through VD3 simultaneously, the C2 fast charge of VD4, and 2 pin of IC are high potential, and at this moment as BK Brake Switch K1 action, 2 pin no longer are triggered, and 3 pin are exported active potential all the time.VT1 ends, the VT2 conducting, and VT3, VT4 does not work.C1 in the circuit, C4 is a filter capacitor, and VD7 plays pressure stabilization function, and R1 plays metering function, damages circuit component for preventing that input voltage from raising.VD1, VD2 prevent the power line voltage reversal connection and are provided with that motor bike also can normal operation under the state of no storage battery.

By this kind improvement, when BK Brake Switch is moved, start by time delay circuit, the control circuit that oscillating circuit and reactive circuit are formed, when making stoplight stop lamp bright, the Cornering Lamp stroboscopic has strengthened the brake alarm signal.
