Description
Technical field
The utility model relates to automobile fitting technical field, is specifically a kind of automobile safety belt reminding system.
Background technology
The speed of modern automobile is very fast, once collide, and vehicle body stop motion, and passenger's body can move forward due to inertia, in Che Nei and vehicle body strikes, Windshield may be crashed and fly out forward outside window time serious.For preventing, when colliding, similar injury occurs, public security department requires that small-sized bus man and front-seat passenger must use of seat belts, so that when there is traffic accident, safety strap plays the effect of buffering to people, prevents secondary injury.On high-grade car, except front, back row seats have outside safety strap, are also installed with air bag system, once get into an accident, air bag will eject by automatic inflating, avoids people to bump against on vehicle body.
The effect of safety strap primary protection has:
1) deceleration/decel when antagonism is collided, make driver and crew unlikely with bearing circle, instrument carrier panel and Windshield etc. article generation secondary impact;
2) by the progradation of safety strap, can the effect of buffer deceleration power once again;
3) prevent the driver and crew's Emergency time in car from being dished out outside car.
At present, all vehicles all possess prompting function of not fastening the safety belt in steerman side, and some vehicle copilot side possesses too.Steerman great majority are fastened the safety belt after can accomplishing to get on the bus, but other passengers consciousness of generally not fastening the safety belt and custom, once there is traffic accident, consequence is hardly imaginable.Meanwhile, steerman is supervised repeatedly, other passengers also can be made to produce and be sick of psychology.
Summary of the invention
The purpose of this utility model is: provide a kind of automobile safety belt reminding system, and prepare to start when vehicle puts down parking brake, when having passenger to be seated on cushion in car, can send voice message, reminding passengers fastens one's safety belt simultaneously.
The utility model solves the technical scheme that its technical matters adopts: a kind of automobile safety belt reminding system, comprise the cushion be made up of cushion part and back-rest, safety belt reminding device, hand brake lever and hand brake lever base, safety belt reminding device comprises microcontroller, pressure sensor, loud speaker and power supply, pressure sensor is positioned at cushion part inside and is connected with microcontroller, microcontroller is connected with loud speaker, hand brake lever base is positioned at below hand brake lever and is provided with conductive contact one, the position that the bottom of hand brake lever is corresponding with conductive contact one is provided with conductive contact two, conductive contact one is connected with power supply, conductive contact two respectively with microcontroller, pressure sensor, loud speaker is connected, the connection lead that power supply is connected with conductive contact one is provided with source switch.
Further, described microcontroller adopts model to be the micro controller system of AT89C51.
The utility model compared with prior art, have the following advantages: the utility model automobile safety belt reminding system, prepare to start when vehicle puts down parking brake, when having passenger to be seated on cushion in car simultaneously, voice message can be sent, reminding passengers fastens one's safety belt, and alleviates the degree come to harm because of traffic accident.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of the utility model automobile safety belt reminding system.
Fig. 2 is the structural representation of the cushion related in the utility model.
Shown in figure: 1, cushion 11, cushion part 12, back-rest 2, microcontroller 3, pressure sensor 4, loud speaker 5, power supply 6, conductive contact 1, conductive contact 28, boss 9, source switch 10, hand brake lever 11, hand brake lever base.
Detailed description of the invention
Below by drawings and Examples, the utility model is further elaborated.
As depicted in figs. 1 and 2: a kind of automobile safety belt reminding system, the cushion 1, safety belt reminding device, hand brake lever 10 and the hand brake lever base 11 that are made up of cushion part 11 and back-rest 12 is comprised.Safety belt reminding device comprises microcontroller 2, pressure sensor 3, loud speaker 4 and power supply 5.Pressure sensor 3 is positioned at cushion part 11 inside and is connected with microcontroller 2, and microcontroller 2 is connected with loud speaker 4.Hand brake lever base 11 is positioned at below hand brake lever 10 and is provided with conductive contact 1, the position that the bottom of hand brake lever 10 is corresponding with conductive contact 1 is provided with conductive contact 27.Conductive contact 1 is connected with power supply 5, and conductive contact 27 is connected with microcontroller 2, pressure sensor 3, loud speaker 4 respectively.The connection lead that power supply 5 is connected with conductive contact 1 is provided with source switch 9.
When hand brake lever 10 is put down, conductive contact 1 contacts with conductive contact 27, makes two conductive contact mutual conduction, and power supply 5 bio-occlusion microcontroller 2, pressure sensor 3 and loud speaker 4 are powered; When hand brake lever 10 pull-up, conductive contact 27 and conductive contact 1 depart from, and power supply 5 stops powering to microcontroller 2, pressure sensor 3 and loud speaker 4.
In order to when ensureing that hand brake lever 10 is put down, conductive contact 1 can contact smoothly with conductive contact 27, hand brake lever base 11 is positioned at below hand brake lever 10 and is provided with boss 8, conductive contact 1 is arranged on boss 8.So greatly can shorten the distance of conductive contact 1 and conductive contact 27, when ensureing that hand brake lever 10 is put down, conductive contact 1 can contact smoothly with conductive contact 27.
Be provided with interlayer in cushion part 11, pressure sensor 3 is positioned at interlayer.During concrete enforcement, microcontroller 2 adopts model to be the micro controller system of AT89C51.Microcontroller 2 and power supply 5 are also all positioned at this interlayer, and so design can not affect the traveling comfort of passenger.Source switch 9 is positioned on the left of main driving cushion part 11, and loud speaker 4 is positioned at the pillowcase of back-rest 12 upper end.
Principle: when source switch 9 closes, and when parking brake puts down preparation startup, power supply 5 gives microcontroller 2, pressure sensor 3, loud speaker 4 supply regular power.Now, if there is passenger to be sitting on cushion 1, pressure sensor 3 just can detect pressure signal, simultaneously by the signal transmission that detects in microcontroller 2, send the prompt tone of not fastening the safety belt by microcontroller 2 control loudspeaker 4, fasten one's safety belt with reminding passengers.For copilot side, when not having passenger or parking brake not to put down, safety belt reminding device can not ring.Only take passenger and vehicle parking brake put down prepare start time alarm just can sound (do not detect and whether fasten the safety belt), source switch 9 can be opened if worn.
During use, when steerman is sat after in car, source switch 9 is closed.If there is passenger to be seated on cushion 1, and put down hand brake lever 10 when preparing to start, the voice message that loud speaker 4 can send " safety strap is little, safety is large " etc., reminding passengers fastens one's safety belt.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff in the scope not departing from this invention thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its scope protected according to right.
