Description
Affiliated technical field
The utility model belongs to the automotive safety technical field.
Background technology:
The automobile that is parked in the roadside opens the door suddenly, is easy to blow down back pedestrian by bike, causes the contingency that can not envision.Car door throws open in the automobile normal running, and the passenger in the car is easy to be thrown out of outside the car.
If a kind of vehicle safety system is arranged, there is the people to come by bike in the automobile back, during soon near automotive door, just can the locking automotive door also remind the passenger " to have the people to note opening the door behind the car " simultaneously, just can prevent that automobile door opening from blowing down pedestrian's accident generation.Car door in the automobile normal running, the locking car door just can prevent that car door is opened in the automobile normal running.
By top analysis, I determine to adopt ultrasonic testing automobile back pedestrian by bike.Super sonic directive property is strong, and expenditure of energy is slow, and is far away in meson kind propagation distance.Speed sensor with automobile detects car speed, and automobile is the locking car door under steam.The utility model provides a kind of safety system of automobile door opening.Native system according to car after cyclist's speed, people's speed of walking and cyclist's speed distinguished treats, driver or the passenger speed of coming over is slow just without the locking car door.Cyclist's speed is than soon with regard to the locking car door.Calculate the super sonic time of return by SCM program, time of return is conversed pedestrian's speed by bike, if the cyclist comes, micro controller system just sends instruction locking automotive door or reminds the passenger of the door of driving to note opening the door, if cyclist's speed is very slow, the automotive door normal door.In automobile normal running, children do not note car door opening is easy to have an accident.Native system is with regard to the locking car door in the automobile normal running, when car speed approaches zero and the not locking car door when not having the cyclist to come of car rear.
Summary of the invention
Adopt to solve automobile behind the present invention and open the door suddenly and blow down back pedestrian by bike, prevent from simultaneously to open the door suddenly in the running car.A kind of automobile door safety system is made up of speed sensor circuit, ultrasonic testing circuit and single chip circuit; 1, the delivery port P1.0 of micro controller system U1, aerotron V1, ultrasonic emitting probe LS1 form ultrasonic transmit circuit, are formed super sonic and are accepted circuit by micro controller system U1 input port P0.0, integrated decode block U8, integrated transporting discharging U10 and U9, super sonic acceptance probe LS2 again; 2, pyroelectricity module U7, micro controller system U1 input port P0.1 form in the pyroelectric sensor inspection vehicle whether people's circuit is arranged, and have man-hour to start vehicle safety system in the inspection vehicle; 3, form hand near induction type circuit start native system voice reminder circuit near induction module U6, micro controller system U1 input port P0.3; 4, automotive speed sensor U5, micro controller system U1 car speed detection port P0.5 formed automobile speed detect the loop; 5, form the voice reminder circuit by micro controller system U1 its enable port P2.0 and close port P2.1, voice reminder module U4, loud speaker LS3; 6, open electromagnetic lock port P2.2 by micro controller system U1 and close electromagnetic lock port P2.3, electromagnetic lock module JCDXS forms the electromagnetic lock circuit; 7, button SB2, micro controller system U1 input port P0.7 form startup or close native system car door blocking function circuit.
The technical scheme that its technical matters that solves the utility model adopts is
Native system does not start super sonic locking car door circuit in automobile normal running, a toggle speed sensor occlusion car door circuit.1) by automotive speed sensor OES the car speed signal being sent into native system micro controller system U10 input port P0.5 calculates through micro controller system U1.Direct locking car door in the running car, if during parking of automobile by the ultrasonic testing circuit according to alternative condition locking car door.2) after native system micro controller system U1 output port P1.0 output signal amplifies through aerotron V1, through ultrasonic transmitter LS1 (TCT40-16T) output ultrasonic wave, after super sonic receiver LS2 (TCT40-16R) receives the super sonic that reflects, amplify through integrated operational amplifier U9, U10 (LM324), pass through integrated decode block U8 (LM567) again the super sonic that reflects is sent back to micro controller system U10 input port P0.0, whether micro controller system determines the locking car door according to cyclist's velocity magnitude.3) whether native system is with having the people in pyroelectricity module U7 (RE200B) inspection vehicle, if nobody just should close the native system protective circuit.Pyroelectricity module U7 (RE200B) will detect letter input micro controller system U1 input port P0.1, calculate whether start protective circuit through micro controller system U1.4) native system is used near induction module U6 (MC030), and the passenger sends starting this device voice reminder LS3. (when condition has the cyclist after native system detects car) when opening the door handle in the inspection vehicle: " having people's locking to open the door behind the car ".5) native system micro controller system U1 is according to two output port P2.2 of calculation control (unlatching) electromagnetic lock U3 (JCDXS) or P2.3 (closing) electromagnetic lock U3 (JCDXS).6) native system locking car door function can be selected whether to drop into or be withdrawed to native system according to user's specific (special) requirements by button SB2.7) in system's effective monitoring scope, micro controller system has been controlled the hypracoustic efficient range on launch time.The invention has the beneficial effects as follows, remedy automobile and when opening the door, blown down the leak that opens the door suddenly in back cyclist and the running car, prevent in the running car that the passenger opens the door and cyclist's locking car door, sound prompt function arranged behind locking, the car, can guarantee passenger and cyclist's personal safety, stop the generation of human casualty accident.
