Description

Rear-mounted multifunctional electronic safety indicator for motor-driven vehicle

The utility model relates to a kind of telltale, the rearmounted multifunction electronic security display of particularly a kind of self-propelled vehicle.

In the self-propelled vehicle of producing at present both at home and abroad, most rearmounted safety light is all former thereby be arranged on shorter position because of the integral layout of self-propelled vehicle, and this situation car and motor bike are more outstanding.Modern big and medium-sized cities traffic is more and more busier, self-propelled vehicle often because of heavy traffic so that low running speed is followed nearerly, the rearmounted safety light of front truck shortly is difficult for seeing clearly (this situation with cart with dolly for very) because of being provided with, car accident takes place easily.At this reason, some producer sets up an indicator lamp in the higher position rear seat windscreen of dolly recently, but has only when brake just bright on this device basic, function singleness.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of various indicating status are made summary display, and is installed in the self-propelled vehicle rear seat windscreen, with the rearmounted multifunction electronic security display of the self-propelled vehicle that improves travel safety.

The purpose of this utility model can reach by following measure: the utility model comprises housing, permanent seat, it is characterized in that: also have control circuit, LED display, four control end L, R of control circuit, E, S accept respectively from the signal that self-propelled vehicle left and rightly turns to, night travel and brake are sent here, and its mouth is delivered to A, B, C, the D end of LED display respectively.

The purpose of this utility model can also reach by following measure: LED display is loaded on the front of housing, and whole housing is contained in the self-propelled vehicle rear seat windscreen by permanent seat.Right steering signal input part R passes through D1, D7 and aerotron T1, the base stage of T2 is joined, pass through D2, the emitter-base bandgap grading of D3 and T1～T3 joins, pass through D2, the emitter-base bandgap grading of D9 and aerotron T4 joins, left direction signal input end L passes through D5, D6 and T3, the base stage of T2 is joined, pass through D4, the emitter-base bandgap grading of D3 and T1～T3 joins, pass through D4, the emitter-base bandgap grading of D9 and T4 joins, night travel signal input part E passes through D8, the emitter-base bandgap grading of R4 and T1～T3 joins, brake signal input end S passes through D10, the emitter-base bandgap grading of D9 and T4 joins, pass through D10, the emitter-base bandgap grading of D3 and T1～T3 joins, the collecting electrode of aerotron T1～T4 respectively with the A of LED display 2, D, B, the C end joins.

Fig. 1 is a functional-block diagram of the present utility model;

Fig. 2 is a contour structures scheme drawing of the present utility model;

Fig. 3 is an electrical schematic diagram of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, the utility model is made up of control circuit 1 and LED display 2 two large divisions.LED display 2 is contained in the front of housing 3, and whole housing 3 is contained in the dolly rear seat windscreen by permanent seat 4.Read-out 2 is made luminary by red high-brightness LED (light-emitting diode), evenly arranges, and is divided into A, B, C, D four parts, constitutes 11 kinds of functions by control and shows.

As shown in Figure 3, T1, T2, T3 and T4 control LED display A, D, B and C part respectively.When being used as the right steering indication, R high level (L, E and S are low level), the emitter-base bandgap grading of T1, T2, T3 and T4 gets, but simultaneously high level is caused the base stage of T1 and T2 because of D1 and D7, so the time have only T3 and T4 conducting, LED display B and C two parts are bright, and it is bright promptly to point to right-hand arrow, realize the right steering indication.When being used as the left steering indication, L high level (R, E and S are low level), the emitter-base bandgap grading of T1, T2, T3 and T4 gets, simultaneously high level is caused the base stage of T2 and T3 again because of D5 and D6, so the time have only T1 and T4 conducting, LED display A and C two parts are bright, promptly indicate to the arrow of left brightly, realize the left steering indication.When driving a vehicle night, E is high level (R, L and S are low level), and T1, T2 and T3 emitter-base bandgap grading must conduct, and LED display A, D and B three parts are bright, but because of the step-down of R4, so the time only have an appointment 70% brightness, realize the night travel indication.S is high level (R, L and E are low level) during brake, and T1, T2, T3 and T4 emitter-base bandgap grading must conduct, and the bright realization brake of LED display A, D, B and C four parts shows.When night driving and make right steering, when left steering and brake indication, realize by following approach: (1) right (or left side) is when turning to, R(or L) level be between height and low level, to change with the light on and off of self-propelled vehicle turning indicator, as R(or L) when being high level, though E also is a high level, but because of D1, D7(or D5, D6) with R(or L) high level cause T1, T2(or T2, T3) base stage, so have only T3, T4(or T1, T4) conducting, LED display B, C(or A, C) two is partly bright, the arrow that promptly points to right-hand (or left) is bright, as R(or L) when being low level, E still is high level, LED display A as hereinbefore, D and B three parts are bright; During this period, right (or left side) rotation arrow and night travel indication Alternation Display realize the demonstration that turns to of night travel.When (2) braking, S is a high level, because of the clamper of D3, D10, makes LED display A, B, C and D four part places highlighted (100% brightness) state; When S was low level, E still was a high level, and LED display A, D and B three parts are bright as hereinbefore, realized the brake indication of night travel.Brake during right (or left side) turns to, or do right (or left side) during the brake when turning to indication, S is a high level, and R(or L) level changes with low tone high, as hereinbefore, because D1, D7(or D5, D6) effect, make LED display make right (or left side) rotation arrow and brake indication Alternation Display with going out with the brightness of turning indicator, realize that doing right (or left side) during brake or the brake during right (or left side) turns to turns to indication.When sending the danger warning signal when the self-propelled vehicle et out of order, the level of R and L changes with low tone simultaneously high, because the effect of D1, D5, D6 and D7, the C part that makes LED display is with the synchronous light on and off of danger warning indicator lamp; And in night running, send danger warning when indication when self-propelled vehicle, LED display C part and night travel indication are the light on and off Alternation Display with the danger warning indicator lamp.

Load onto this telltale in the motorcycle helmet lower rear, by terminal pin and motor bike coorespondingly left and rightly turn to, night travel and each control end that brakes link to each other, and can realize that also above-mentioned 11 kinds of functions show.

The utility model has following advantage compared to existing technology:

1. the rearmounted green indicating lamp of motor vehicle various indicating status are under steam made synthesis display, improved the security of driving.

2. clear dazzling, warning function is obvious, and little power consumption, and is reliability and durability, and the circuit advantages of simple can adapt to modern busy traffic needs.
