Abstract
The utility model relates to a kind of drunk-driving prevention engine starting gears, including power supply, alcohol sensor, relay, ignition switch and start motor, the connection of the feeder ear of power supply and alcohol sensor, the output end of alcohol sensor and the coil both ends of relay connect, and the normally-closed contact of relay and common end are connect with ignition switch and starting motor respectively；The normally-closed contact that alcohol sensor is used to control relay when detecting that the alcohol concentration in driver's expiration is more than preset value disconnects, to disconnect ignition switch and start the connection between motor.The utility model is when alcohol sensor detects that the alcohol concentration in driver's expiration is more than preset value, the normally-closed contact for controlling relay disconnects, to disconnect ignition switch and start the connection between motor, so that driver, which is unable to control, starts motor start-up automobile, to effectively prevent the generation of drunk driving behavior.
Description
Technical field
The utility model relates to field of engine control, and in particular to a kind of drunk-driving prevention engine starting gear.
Background technique
Currently, as automobile enters more and more families, drunk driving behavior happens occasionally, causes seriously to traffic safety
Influence.The interim selective examination that traffic police department is relied primarily on currently for the restriction of drunk driving behavior, can not effectively avoid driver
Drunk driving can not avoid the generation of drunk driving behavior from source.
Utility model content
In view of the above technical problems, the utility model provides a kind of drunk-driving prevention engine starting gear.
The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of drunk-driving prevention engine starting gear, packet
It includes power supply, alcohol sensor, relay, ignition switch and starts motor, the power supply of the power supply and the alcohol sensor
End connection, the output end of the alcohol sensor are connect with the coil both ends of the relay, the normally-closed contact of the relay
It is connect respectively with the ignition switch and the starting motor with common end；
The alcohol sensor is used for when detecting that the alcohol concentration in driver's expiration is more than preset value, described in control
The normally-closed contact of relay disconnects, to disconnect the ignition switch and the connection started between motor.
The beneficial effects of the utility model are: the alcohol concentration in alcohol sensor detects that driver exhales is more than pre-
If when value, the normally-closed contact for controlling the relay is disconnected, to disconnect between the ignition switch and the starting motor
Connection so that driver be unable to control start motor start-up automobile, to effectively prevent the generation of drunk driving behavior.
Based on the above technical solution, the utility model can also do following improvement.
It further, further include alarm, the normally opened contact of the relay is connect with the alarm；
The alcohol sensor is used for when detecting that the alcohol concentration in driver's expiration is more than preset value, described in control
The normally opened contact of relay is closed, so that the alarm equipment alarm.
Further, the alarm is combined aural and visual alarm or phonetic alarm.
Further, the alcohol sensor is set on steering wheel.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of drunk-driving prevention engine starting gear provided by the embodiment of the utility model；
Fig. 2 is the structural schematic diagram of another drunk-driving prevention engine starting gear provided by the embodiment of the utility model.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Fig. 1 is a kind of structural schematic diagram of drunk-driving prevention engine starting gear provided by the embodiment of the utility model, such as Fig. 1
Shown, which includes power supply 1, alcohol sensor 2, relay 3, ignition switch 4 and starts motor 5, the power supply 1 with
The feeder ear of the alcohol sensor 2 connects, and the coil both ends of the output end of the alcohol sensor 2 and the relay 3 connect
It connects, the normally-closed contact M and common end Q of the relay are connect with the ignition switch 4 and the starting motor 5 respectively；
The alcohol sensor 2 is used to control institute when detecting that the alcohol concentration in driver's expiration is more than preset value
The normally-closed contact M for stating relay 3 is disconnected, so that the ignition switch 4 and the connection started between motor 5 are disconnected, this
When, when driver's starting ignition switchs, starting motor 5 can not start, and automobile engine also can not just start, so that driving
The person of sailing can not drive a car, to effectively prevent the generation of drunk driving behavior.
Optionally, in this embodiment, as shown in Fig. 2, the device further includes alarm 6, the normally opened touching of the relay 3
Point N is connect with the alarm 6；
The alcohol sensor 2 is used to control institute when detecting that the alcohol concentration in driver's expiration is more than preset value
The normally opened contact N closure of relay 3 is stated, so that the alarm equipment alarm, prompts driver not carry out drunk driving behavior.
Optionally, in this embodiment, the alarm is combined aural and visual alarm or phonetic alarm.
Optionally, in this embodiment, the alcohol sensor is set on steering wheel.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
