Because the utility model is provided with left arrow lamp, right arrow lamp and information warning lamp on described read-out; Described left arrow lamp, right arrow lamp and information warning lamp are connected with stoplight stop lamp with left-hand lamp, the dextrad lamp of self-propelled vehicle with stoplight stop lamp contact A by the left lamp contact C of control setup, right lamp contact D respectively, make when driving, left side arrow lamp, right arrow lamp and information warning lamp have played tangible warning function along with lighting of left and right lamp and stoplight stop lamp lighted simultaneously.In addition, the control setup that the utility model adopts also comprises individual character driving circuit, display control circuit and whole driving circuit, and described information warning lamp also comprise can independent displaying the caution word, described control setup correspondence comprises the control joint of above-mentioned caution word, described caution word is connected respectively with caution word joint, like this, makes under the control of control circuit, each caution word can show that warning function is stronger by different patterns.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the scheme drawing of an embodiment of the utility model;

Fig. 2 is the control setup logical schematic that the utility model embodiment adopts;

Fig. 3 is the circuit diagram of the actual enforcement of Fig. 2.

At first with reference to figure 1.Fig. 1 is first embodiment of the present utility model.The described vehicle safety annunciator of Fig. 1 comprises headlight K switch 3, left/right lamp switch K2, braking signal switch K1, also comprises read-out 1 and control setup 2, is provided with left arrow lamp 11, right arrow lamp 12 and information warning lamp 13 on described read-out 1.Above-mentioned left arrow lamp 11, right arrow lamp 12 show when being used for motor turning, above-mentioned information warning lamp 13 comprise can independent displaying the caution word, all caution words of whole information warning lamp 13 can whole show, also can independent displaying, form abundant display format.Can make by light-emitting diode or common bulb in above-mentioned information warning lamp 13 reality; Described left arrow lamp 11, right arrow lamp 12 and information warning lamp 13 are connected with stoplight stop lamp with left-hand lamp, the dextrad lamp of self-propelled vehicle with stoplight stop lamp contact A by the left lamp contact D of control setup 2, right lamp contact C respectively; The positive pole of described control setup 2 is connected with the normally closed contact of headlight K switch 3, left/right lamp switch K2, braking signal switch K1, is connected the positive pole of power supply; By above-mentioned connection, when left/right lamp switch K2 dialled to the dextrad lamp, right arrow lamp 12 and dextrad lamp were lighted simultaneously, when left/right lamp switch K2 dials to the left-hand lamp, left side arrow lamp 11 and left-hand lamp are lighted simultaneously, and when braking signal switch K1 dialled to stoplight stop lamp, information warning lamp 13 and stoplight stop lamp were lighted simultaneously.

For making vehicle safety annunciator described in the utility model have abundanter, strong caution effect, the control setup 2 that adopts at the utility model embodiment is provided with individual character driving circuit 21, display control circuit 22 and whole driving circuit 23, the mouth of described display control circuit 22 and whole driving circuit 23 is connected with the individual character control input end with the whole control input end of individual character driving circuit 21 respectively, and described individual character driving circuit 21 mouths are connected with the input end of information warning lamp 13; Described individual character driving circuit 21 is used to drive the demonstration that each independently warns word; Described display control circuit 22 is used to control individual character driving circuit 21, therefore pass through the control of 22 pairs of individual character driving circuits 21 of display control circuit, make each caution word to show in a different manner, for example roll display, the demonstration of beating, whole demonstration etc., and then the variation of the display format of control caution word, produce colourful display effect; Described whole driving circuit 23 is used for control and drives individual character driving circuit 21, and each caution word is shown simultaneously.With reference to figure 2.
