Abstract
The utility model discloses a motor vehicle safety belt lock which comprises a safety belt alarming switch, an intermediate relay and an electronic controlling unit. The safety belt alarming switch is arranged inside the socket of the safety belt and corresponds to the buckle of the safety belt, one end of a normally open contact of the safety belt is connected with power ground, the other end of the normally open contact of the safety belt is connected with the input end of the electronic controlling unit, one end of the controlling coil of the intermediate relay is connected with the power ground, the other end of the controlling coil of the intermediate relay is connected with the output end of the electronic controlling unit, and the normally open contact is connected in the starting loop of a vehicle in a series mode. According to the motor vehicle safety belt lock, the safety belt alarming switch is used for monitoring the state of the safety belt, and the electronic controlling unit receives the monitoring signal output by the safety belt alarming switch and controls on-off of the starting loop of the vehicle through the intermediate relay. The vehicle is allowed to start only a driver fastens the safety belt, and therefore the situation that the driver starts the vehicle under the situation of forgetting fastening the safety belt is prevented, and personal safety of the driver is ensured.
Description
Technical field
The utility model relates to a kind of device that can forbid vehicle launch when automobile driver is not fastened the safety belt, belongs to automobile technical field.
Background technology
Safety strap is the important safety of self-propelled vehicle, can effectively protect chaufeur and occupant's safety when the vehicle accident.Although people's awareness of safety constantly strengthens, the chaufeur that some new hands is always arranged or do not form good habit is forgotten when driving and is fastened the safety belt, thereby the personal safety of chaufeur is brought hidden danger.Therefore, how effectively to prevent chaufeur in the situation that forget that fastening the safety belt drives a car is the difficult problem that the relevant personnel face always.
The utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of automobile safety with lock, prevents chaufeur in the situation that forget the steering vehicle of fastening the safety belt.
Problem described in the utility model realizes with following technical proposals:
A kind of automobile safety is with lock, comprise safety strap alarm switch, intermediate relay and electronic control unit in the formation, described safety strap alarm switch is installed in the socket of safety strap and is corresponding with the buckle of safety strap, its open contact one end bonding, the input end of one termination electronic control unit, the control coil one end bonding of described intermediate relay, the mouth of a termination electronic control unit, its open contact are serially connected in the startup loop of vehicle.
Above-mentioned automobile safety is with lock, and the open contact of described intermediate relay also is serially connected in the control circuit of igniting system for motor vehicle and fuel-feed system.
Above-mentioned automobile safety is with lock, and the coupling end of described safety strap alarm switch and electronic control unit is provided with pull-up resistor.
Above-mentioned automobile safety is with lock, and described electronic control unit adopts self-propelled vehicle control computer.
The utility model utilizes the state of safety strap alarm switch monitoring safety strap, electronic control unit receives behind the monitor signal of safety strap alarm switch output the break-make by intermediate relay control vehicle launch loop, only have and after chaufeur is fastened seat belts, just allow vehicle launch, so effectively prevent chaufeur in the situation that forget to fasten the safety belt and start vehicle, thereby guaranteed the personal safety of chaufeur.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is electrical schematic diagram of the present utility model.
Each list of reference numerals is among the figure: ECU, electronic control unit, K1, safety strap alarm switch, K2, starting switch, J1, intermediate relay, J2, starting relay, F, fusible line, B, storage battery, QD, starter motor, R, pull-up resistor.
The specific embodiment
Referring to Fig. 1, the utility model comprises electronic control unit ECU, safety strap alarm switch K1 and intermediate relay J1, and safety strap alarm switch K1 is installed in the safety strap socket.Starting switch K2 among Fig. 1 and starting relay J2 are used for control starter motor QD.
After safety belt buckle inserts socket, safety strap alarm switch K1 is triggered, its open contact is closed, with electronic control unit ECU(self-propelled vehicle control computer) level of input end drags down, electronic control unit ECU makes intermediate relay J1 action after receiving this signal, the open contact of intermediate relay J1 is closed, and self-propelled vehicle can normally be started.Forget that when chaufeur when fastening the safety belt, the open contact of intermediate relay J1 disconnects, even this moment, starting switch K2 was closed, the coil of starting relay J2 can not get electric yet, and vehicle can't start.
For gasoline car, the open contact of intermediate relay J1 also can be serially connected in the control loop of high-tension coil, and chaufeur forgets when fastening the safety belt, and high-tension coil can't be worked, and vehicle can't start equally.The utility model also can also be included the control circuit of self-propelled vehicle " ignition system " and " fuel-feed system " in range of control, like this behind motor vehicle starting, chaufeur also can stop working as safety strap is removed, and must fasten the safety belt when driving thereby thoroughly limit chaufeur.
In addition, electronic control unit ECU receives that safety strap is not can also give the alarm by warning behind the signal, is reminded chaufeur.As safety belt buckle is extracted socket, electronic control unit ECU can only close start-up system, ignition system or fuel-feed system, but can not have influence on steering swivel system and brake system, thereby, prevent from causing other accident.
In addition, contacting between safety belt buckle and the socket can be designed to one to one, just as automobile key, only has a buckle can make this device work, wears Safety Belt thereby limited to the full extent chaufeur.
