Description

A kind of automobile limit is sailed telltale

Technical field

The utility model relates to a kind of automobile accessory, especially a kind of sound prompt device that is used to remind chaufeur rest in time or replaces chaufeur.

Background technology

At present domestic chaufeur is the fatigue driving ubiquity when driving, and especially enters express highway, and distance is long, and chaufeur is tired easily, and the probability that has an accident increases greatly.Abroad, some national traffic law has stipulated that continuous driving must not fatigue driving.

Summary of the invention

Technical problem to be solved in the utility model is to propose a kind of in the driver drives vehicle prompting that can give the alarm earlier after a period of time, and telltale is sailed in the back flame-out automobile limit of outage automatically, thereby plays the effect that reduces fatigue driving.

For solving the problems of the technologies described above, technical characterictic of the present utility model is: a kind of automobile limit is sailed telltale, form by timer, chip, loud speaker, switch, circuit links to each other with automobile circuit, timer is connected with automobile power supply switch, timer connects with chip, loud speaker, and the timing of timer can be regulated, interior dress automatic power-off switch.

The utility model has can be reminded chaufeur in time to have a rest or replace chaufeur, reduces fatigue driving, thus the effect of life security during the better guarantee driving.
