Abstract
A fatigue driving pre-alarm relates to a device using sounds to alarm a tired driver. The fatigue driving pre-alarm is composed of a group of grasping switches, a main switch, a relay, a music playing chip, a loudhailer and batteries. One end of the batteries is respectively connected with a pole of a relay coil and a pole of the music playing chip, the other end of the batteries is divided into two lines after passing through the main switch, one line is connected with the relay coil via the grasping switches, the other line is connected with the other pole of the music playing chip via the normally-closed contact of the relay, and the loudhailer is connected with the music playing chip. The fatigue driving pre-alarm with simple structure and low cost can efficiently awake the driver in driving by sounds.
Description
Technical field
A kind of fatigue driving precaution device relates to a kind of device that utilizes sound prompting fatigue driving person.
Background technology
Fatigue driving is one of the main cause that causes a traffic accident.According to statistics, the traffic hazard of China 1/3 is caused by fatigue driving.Yet there are no similar products like in the market.
The utility model content
The purpose of this utility model provides a kind of when driver fatigue, utilizes the device of its attention of sound prompting.
This fatigue driving precaution device is to be made of one group of grip pressure formula switch, master switch, relay, music chip, loudspeaker and battery; One utmost point of battery links with the utmost point of relay coil and music chip respectively, another utmost point of battery is divided into two-way after by master switch, leading up to grip pressure formula switch and relay coil links, another road links by the normally closed contact of relay and another utmost point of music chip, and loudspeaker and music chip link.
This fatigue driving precaution device is contained in grip pressure formula switch on the automobile steering wheel in use, and the outside puts direction indicators cover, and other parts can be fitted together, and is put in any position in the pilothouse.During driving, hold bearing circle, closed master switch.When a little, one or more closings of contact of grip pressure formula switch are connected.At this moment, relay power, its normally closed contact disconnects, and the outage of music chip is not worked.When driver fatigue was sleepy, hand can break away from bearing circle, and grip pressure formula switch disconnects, the relay outage, and its normally closed contact is connected, and the music chip is switched on, and sends the sound by loudspeaker, reminds the driver to note.
This fatigue driving precaution device is simple in structure, and cost is low, can effectively remind the driver to drive by sound.
Description of drawings
Fig. 1 is the connection synoptic diagram of each parts of this fatigue driving precaution device.
