Abstract
The utility model discloses a steering lamp twinkling device of an electric vehicle. The steering lamp twinkling device of the electric vehicle comprises a 12V direct current power supply, an oscillating circuit, a phonation circuit and a steering lamp conversion circuit. The steering lamp twinkling device of the electric vehicle is characterized in that the model number of an oscillator IC1 in the oscillating circuit is LM3909. The steering lamp twinkling device of the electric vehicle uses an oscillator chip manufactured by the company of American country semiconductor; only a timing capacitor is used to form a twinkling circuit at the periphery of the LM3909, and the circuit can directly drive the steering lamp and the speaker to work at the same time. A voice prompt function is added, therefore, the working state of the steering lamp is indicated on one hand, and a driver is reminded to timely turn off the steering lamp after turning a corner on the other hand. The circuit has the advantages of high integration degree, stable twinkling frequency, anti-vibration performance and reliable operation, and the phenomenon of ablating a trigger contact is completely eradicated.
