Description

Do not insert safety strap time-delay retarder

Technical field

The utility model relates to a kind of auto-safety mechanism, relates in particular to a kind of safety strap time-delay retarder of not inserting.

Background technology

According to " People's Republic of China's law on road traffic safety " regulation, during motor-driven vehicle going, steerman, passenger should use of seat belts by as prescribed.Traffic law does not in recent years have the driving behavior punishment of wear safety belt more and more severeer to the driver, in the driver driving process whether wear safety belt will become the new emphasis of the safety of driving.

Because current driver's quality is relatively poor, wear safety belt is uncomfortable just not to be worn, in case occurrence of traffic accident, the speed when safety air bag is opened is up to 300km/h, and human body head moment contact impulse force can produce huge injury to human body up to the hundreds of kilogram.Safety strap becomes at present effective passive safety apparatus as main occupant restraint fender guard.According to statistics, the correct wear safety belt of navigating mate gets into an accident, and positive collision can make mortality reduce 57%, and colliding and can make mortality reduce 44% in the side, can reduce 40% during overturning.Yet China's manned vehicle safety strap condition of service but allows of no optimist, and data in 2005 show that China's manned vehicle operating seat seatbelt wearing rate is merely 68%, and are all lower than each developed country's manned vehicle seatbelt wearing rate.In order to change the not bad habit of wear safety belt of chaufeur, be necessary to adopt a kind of later-model, remind more obviously, more perfect functions, be prone to received device and improve the seatbelt wearing rate.

The present safety strap suggestion device of not inserting has the loudspeaker voice reminder, makes the driver think that agitation makes the actual effect of wear safety belt unsatisfactory owing to sending the voice suggestion meeting in the car; Also have the safety strap warning light, but tend to still can forget wear safety belt because the safety strap warning light is not obvious.

Summary of the invention

The utility model provides a kind of safety strap time-delay retarder of inserting, and can not control the speed of a motor vehicle during wear safety belt the driver and reduce and limit the speed of a motor vehicle.

In order to achieve the above object, the utility model is taked following technical scheme:

Do not insert safety strap time-delay retarder; Comprise automobile power supply switch, delay timer, speed detector and fuel injector; The corresponding electrical connection of the input end of speed detector with delay timer, the corresponding electrical connection of the mouth of speed detector with speed relay, speed relay respectively with fuel injector, the corresponding electrical connection of automobile power supply switch; The corresponding electrical connection of fuel injector with delay timer, the corresponding electrical connection of delay timer with automobile power supply switch.Be electrically connected corresponding of one end of line pressure switch and primary pressure sensor parallel branch with automobile power supply switch, the corresponding electrical connection of the other end with main relay, main relay respectively with delay timer, automobile power supply switch, mainly drive the corresponding electrical connection of seat belt switch; One end of secondary pressure switch and secondary stress sensor parallel branch with the line pressure switch, the primary pressure sensor parallel branch is corresponding is electrically connected; The corresponding electrical connection with secondary relay of the other end, secondary relay are driven the corresponding electrical connection of seat belt switch with delay timer, automobile power supply switch, pair respectively.The corresponding electrical connection of deceleration warning light with delay timer.

When the driver is sitting in main driving on the seat, if chaufeur does not have wear safety belt, the main seat belt switch of driving breaks off.The line pressure switch closure of installing in the seat through the closed automobile power supply switch of automobile key, is connected automobile power source; Primary pressure sensor is started working, and senses and takes down, and the closure signal of line pressure switch and primary pressure sensor starts delay timer work through main relay; If the driver has not also worn safety strap in the delay time that delay timer sets, the start signal of line pressure switch and primary pressure sensor control deceleration warning light is bright, and delay timer closing signal control this moment fuel injector breaks off; Thereby control is slowed down; This moment delay timer actuation signal control rate sensors work, speed detector closing signal control fuel injector breaks off, and can limit the speed of a motor vehicle after the deceleration; Prevent that the driver from arbitrarily quickening automotive engine is caused damage, also guaranteed driving safety in the time of speed limit.If chaufeur is found the bright back of deceleration warning light wear safety belt in time, the main seat belt switch closure of driving, closure signal is closed delay timer, the light on and off of deceleration warning light, speed detector through main relay and is quit work, and removes speed limit.

When the passenger is sitting on the vice operator's seat chair, if the passenger does not have wear safety belt, pair is driven seat belt switch and is broken off.The closure signal of secondary pressure switch and secondary stress sensor starts delayer work through secondary relay; If the passenger has not also worn safety belt in the delay time that delayer sets; The start signal control deceleration warning light of secondary pressure switch and secondary stress sensor is bright; Delayer shutdown signal control this moment fuel injector breaks off; Thereby control is slowed down; This moment delayer enabling signal control rate sensors work; Speed detector shutdown signal control fuel injector breaks off; Can limit the speed of a motor vehicle after the deceleration; The timely wear safety belt in the bright back of warning light if the passenger finds to slow down; Pair is driven the seat belt switch closure; Closure signal is closed delayer through main relay; The light on and off of deceleration warning light; Speed detector quits work, and removes speed limit.

When nobody takes on the vice operator's seat chair, send secondary pressure switch and secondary stress sensor actuation signal by line pressure switch and primary pressure sensor and control the delay timer delayed startup and detect speed limit.

The above-mentioned safety strap time-delay retarder of inserting also comprises the emergency recovery switch, emergent relay respectively with emergency recovery switch, delay timer, the corresponding electrical connection of main relay, the corresponding electrical connection of emergency recovery switch with automobile power supply switch.

The utility model is simple in structure, and the mode of utilizing delay timer to control the fuel injector deceleration is reminded driver and passenger's wear safety belt, and the speed of a motor vehicle that limits after slowing down has ensured that traffic safety has also reduced the infringement of deceleration to driving engine simultaneously.
