Detailed Description

As shown in fig. 2-3, a driving state suggestion device' S controller mainly include a group relay K1, control chip U1, trigger switch S2, step-down resistance R, filter capacitance C, thyristor VS and a plurality of binding post. The group-one relay K1 is provided with a group-one first normally open contact K-1, a group-one second normally open contact K-2, a group-one first normally closed contact K-3 and a group-one second normally closed contact K-4 which correspond to each other. The positive electrode of the first relay K1 is connected with the second connecting terminal J2, and the negative electrode of the first relay K1 is connected with the third connecting terminal J3 after being positively connected with the thyristor VS. One end of the trigger switch S2 is connected with the second connecting terminal J2, and the other end is connected with the control end of the thyristor VS. The positive electrode input end of the control chip U1 is connected with a first normally open contact K-1 in series and then connected with a first wiring terminal J1, the negative electrode input end is connected with a second normally open contact K-2 in series and then connected with a third wiring terminal J3, the positive electrode output end of the control chip U1 is connected with a second normally closed contact K-4 in series and then connected with a third wiring terminal J3, and the negative electrode output end is connected with a first normally closed contact K-3 in series and then connected with a first wiring terminal J1. The positive electrode output end of the control chip U1 is further connected with a seventh wiring terminal J7, and the negative electrode output end of the control chip U1 is further connected with a sixth wiring terminal J6. The positive electrode input end of the control chip U1 is further connected with a fourth wiring terminal J4, and the negative electrode input end of the control chip U1 is further connected with a fifth wiring terminal J5. The voltage reduction resistor R and the trigger switch S2 are connected in series and then connected between a second connecting terminal J2 and the control terminal of the thyristor VS. And the filter capacitor C is connected between the control end of the thyristor VS and the cathode in parallel. The filter capacitor C is used to prevent the thyristor VS from being triggered by voltage fluctuations.

The prompting device comprises the controller, and then further comprises a driving lamp L1, a first prompting lamp L4 and a sounder Spk. The running lamp L1 is positively connected to the voltage output terminal of the control chip U1, and the first indicator lamp L4 is reversely connected to the voltage output terminal of the control chip U1. The sounder Spk is connected in parallel to the voltage input terminal of the control chip U1.

When the prompting device works, the prompting device is connected to a running lamp power supply end V1 through a first wiring terminal J1, a second wiring terminal J2 is connected between a brake lamp switch S1 and a brake lamp L2, and a third wiring terminal J3 is connected to a voltage negative end of a vehicle working main circuit or is connected to the common ground. The driving lamp L1 and the first warning lamp L4 form a lamp unit, and the lamp unit only has two pins outwards. After the original driving lamp is detached, the two pins of the lamp unit are connected to the lamp holder of the original driving lamp, and then in-situ installation can be achieved.

When the vehicle is normally driven: the driving lamp power supply end V1 outputs 12V, and the current flows back to the third connecting terminal J3 through the first connecting terminal J1, the first normally closed contact K-3, the driving lamp L1 and the second normally closed contact K-4 in sequence to form a working loop. The running light L1 lights up and the other lights turn off.

When braking is needed and walking is not needed: the running light power supply terminal V1 maintains a 12V output. The brake lamp switch S1 is closed, the brake lamp supply terminal V2 outputs 12V to the brake lamp L2, and the second connection terminal J2 simultaneously receives 12V input. However, the thyristor VS remains off, so the group one relay K1 does not operate, the first indicator light L4 remains off, and the running light L1 remains normally on.

When the bicycle needs to be driven after braking: in the braking state, the driver manually activates the trigger switch S2 again. At the moment, the thyristor VS is electrified and conducted, and the relay K1 is also electrified and works simultaneously. And a group of first normally open contacts K-1 and a group of second normally open contacts K-2 are closed, and a group of first normally closed contacts K-3 and a group of second normally closed contacts K-4 are opened correspondingly. The current of the driving lamp power supply end V1 flows back to the third connecting terminal J3 through the first connecting terminal J1, the first normally open contact K-1, the voltage input end of the control chip U1 and the second normally open contact K-2 in sequence to form a loop. The voltage output end of the control chip U1 outputs working voltage to the first indicator light L4 to enable the first indicator light L4 to be turned on, and at the moment, the running light L1 is turned off. If the sounder Spk is installed, the sounder Spk is also powered on to work at the moment, and gives a yield signal outside the vehicle.

After yielding, the circuit automatically returns to a normal driving state after the brake is released, and the logic relation in various states is shown in the following truth table. When the driving lamp power supply terminal V1 is not output, the vehicle is in a non-driving state, so technical analysis is not carried out in the state.

On the basis of the embodiment, the technical scheme can be further optimized, the rear vehicle can know that the vehicle is in the yielding state, and the pedestrian is prevented from being accidentally injured by the tap outer side of the rear vehicle. As shown in fig. 4 and 5, the controller further includes a diode VD, a group two relay K2, an eighth connection terminal J8, a ninth connection terminal J9 and a tenth connection terminal J0, wherein the group two relay K2 is provided with a group two first normally open contact K-6 and a group two second normally open contact K-7. The positive pole of the group two relay K2 is connected with an eighth connecting terminal J8, the negative pole of the group two relay K2 is divided into two branches, one branch is connected with a ninth connecting terminal J9 after being connected with a group two first normally open contact K-6 in series, and the other branch is connected with a third connecting terminal J3. One end of the second normally open contact K-7 is connected with the first wiring terminal J1, and the other end is connected with the tenth wiring terminal J0. And the ninth connecting terminal J9 is connected with the seventh connecting terminal J7. On the basis, the prompting device also comprises a reversing lamp L3 and a second prompting lamp L5. The anode of the reversing light L3 is connected with a tenth connecting terminal J0, and the cathode is connected with a ninth connecting terminal J9. The second prompting lamp L5 is reversely connected in parallel at two ends of the reversing lamp L3. The anode of the diode VD is connected with a tenth connecting terminal J0, and the cathode of the diode VD is connected with a sixth connecting terminal J6.

The backup light L3 and the second warning light L5 constitute another light unit, which also has only two outward pins. After the original backup lamp is disassembled, the refitting principle is the same as that of the lamp unit corresponding to the running lamp L1. The running light L1 and the first warning light L4 may be installed in the vehicle front direction, and the backup light L3 and the second warning light L5 may be installed in the vehicle rear direction.

In normal driving, the current conditions are similar to those described above, and the running light L1 is turned on and the other lights are turned off.

When the vehicle is braked and does not need to be driven, the brake lamp L2 and the driving lamp L1 are turned on, and other lamps are turned off.

After braking and letting go, the first warning light L4 lights up. At this time, the second warning light L5 is also turned on, and the electric circuit passing through the second warning light L5 is the positive voltage output terminal of the control chip U1, the ninth connection terminal J9, the second warning light L5, the tenth connection terminal J0, the diode VD, and the negative voltage output terminal of the control chip U1 in this order. The other light fixtures remain off.

When the vehicle is backed up, the backup lamp switch S3 is closed, the group two relay K2 is electrified to work, namely the group two first normally open contact K-6 and the group two second normally open contact K-7 are closed. The backup lamp L3 is turned on by the running lamp power supply V1 providing the operating voltage, and the running lamp L1 remains on and the other lamps remain off. Because the brake is often needed to be stepped on when backing a car, if the trigger switch S2 is touched by mistake after backing a car and stepping on the brake, the short circuit of the prompting device can be caused, and the driving safety is influenced. Therefore, the set two normally closed contacts K-5 corresponding to the set two relay K2 can be further improved. The group two normally closed contacts K-5 are connected in series between the group one first normally open contact K-1 and the first wiring terminal J1. When the second relay K2 is powered on, the K5 is disconnected, and even if the brake is stepped on and the trigger switch S2 is touched by mistake, the control chip U1 cannot be powered on, so that short circuit is prevented.

The logic relationship of the specific working process is shown in the following truth table:

to sum up, the two connection terminals corresponding to the voltage output end of the control chip U1 output different voltage polarities during normal driving and during driving. Reasonably and properly adjust the state transformation of the lamp, thereby improving the driving safety. And the lamp can be directly refitted in situ on the original vehicle, thereby being very convenient and safe. First warning light L4 and second warning light L5 can be green LED lamp or LED banks, green based on social human cognition, can directly perceived the driving intention of giving way. The control chip U1 can be implemented by various control chips in the prior art, such as a control chip of a flashlight with a flashing function, so that the first indicator light L4 and the second indicator light L5 realize the effects of normally lighting, flashing or rhythmic flashing, and the like. The sounder Spk may be a beeper or other prior art device capable of sounding, and may prestore a passing recording or rhythmically playing the general indication information of the blind, etc. The trigger switch S2 may be a tact switch or a remote switch, etc.

After the brake pedal is pressed down, the brake lamp switch S1 is equivalent to being closed through signal processing of a vehicle original circuit. Similarly, the backup lamp will be turned on after the driver starts the backup function in the original circuit of the vehicle, which is also equivalent to the switch S3 of the backup lamp being turned on. The utility model discloses only utilized backup lamp feed end V3 to the power supply effect of former backup lamp.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
