Abstract
The utility model relates to a vehicle distance display device, in particular to a digital vehicle distance display screen for preventing rear-end collision. The digital vehicle distance display screen for preventing rear-end collision can detect distance away from a vehicle just behind the vehicle and can display the real-time distance between two vehicles by Arabic numerals in running. In the digital vehicle distance display screen, the input end of a data micro-processing unit is electrically connected with a ranging unit; the output end of the data micro-processing unit is electrically connected with a digital display screen; the output end of the data micro-processing unit is also electrically connected with a sound prompting unit; and the digital display screen is fixed on the left upper corner of the rear windshield of the vehicle. According to the digital vehicle distance display screen, vehicle rear-end collision accidents can be furthest avoided, and safety of nation and people life and property can be protected.
Description
Technical field
The utility model relates to the spacing read out instrument, specifically is vehicle detectable dead aft vehicle spacing and show a kind of anti-spacing digital display screen that knocks into the back of real-time spacing with Arabic number when advancing.
Background technology
It is the gratifying performance that people's quality of life improves fast that the family car recoverable amount is significantly increased sharply in recent years, yet the more and more frequent road traffic accident that takes place is again the problem of having to face, wherein vehicle rear-end collision is the extra high class traffic accident of occurrence frequency, also is the inducement that causes all kinds of major traffic accidents.Rear-end collision degree size all can be brought property and spiritual loss to the country and people, even threat to life.Avoid rear-end collision generation chaufeur mainly to grasp at present by range estimation and driving experience, but chaufeur is hard to keep at a kind of stable driving condition because variable factor in the road travel process is more, the visbility that brings as weather conditions descends and the not obvious following distance that makes the chaufeur error in judgement danger occur of object of reference, perhaps chaufeur dispersion attention, visual fatigue is to the strong and weak degree delay of response of brake lamp optical signal, and these all very easily cause the vehicle rear-end collision accident.Improve the chaufeur attention and keep reasonable safe distance between vehicles be the most basic effectively also be the simplest a kind of vehicle rear-end collision measure of avoiding.
The utility model content
The utility model purpose is to solve the strong and weak prompting front vehicle chaufeur that changes of the single forward car light optical signal of present road running vehicle to note the problem that spacing exists, provide a kind of vehicle can monitor the real-time spacing of front vehicle in real time in advancing and directly intuitively be shown to the anti-spacing digital display screen that knocks into the back that the rear chaufeur reads with Arabic number, avoid because of daytime light object of reference at strong or night not clearly rely on the obscure understanding of range estimation and the strong and weak judgement of light spacing that rear-end collision takes place to the rear chaufeur.
Technical solutions of the utility model: a kind of anti-spacing digital display screen that knocks into the back, comprise digital display screen and the range cells that is electrically connected with its input end, it is fixed on the rear seat windscreen of vehicle or the vehicle afterbody.
Between range cells and digital display screen, be electrically connected the data microprocessing unit, be that data microprocessing unit input end is electrically connected range cells, data microprocessing unit mouth is electrically connected digital display screen, also is electrically connected sound Tip element at data microprocessing unit mouth.
Described range cells is the ultrasonic ranging unit.
Described digital display screen is the LED digital display screen.
Described digital display screen fixedly optimum position is the vehicle rear seat windscreen upper left corner.
The utility model beneficial effect: by being arranged on the spacing digital display screen on the front truck rear seat windscreen; in the road travel process; back car chaufeur can be known read the real-time spacing of understanding with front truck intuitively; avoid the chaufeur vision that the external cause variation is brought when road travel to the strong and weak ambiguity of judging of wigwag; the continuous variation of displaying contents can improve the attention of back car chaufeur when driving with car greatly; improper the dwindling by vehicle driver before and after read-out flicker and the sounding while auxiliary prompting of spacing controlled reasonable spacing safe driving; greatly limit avoids the vehicle rear-end collision accident to take place, protection country and people life property safety.
Description of drawings

Fig. 2 is one of a utility model embodiment structural representation.
1 digital display screen among the figure, 2 vehicle rear seat windscreens.
The specific embodiment
The LED digital display screen of the utility model is integrated ultrasonic ranging and data processing function is made up of shell, glass holder support, ultrasonic ranging unit, data microprocessing unit, sound Tip element etc.
As shown in Figure 2, the utility model read-out is installed in the vehicle rear seat windscreen upper left corner and faces dead aft driving vehicle position of driver in the same way, has comprised spacing viewing area and ultrasonic fault detection and region of acceptance on it.
The utility model working power is supplied with by power supply on the vehicle, its anodal car key ignition circuit positive pole that connects, and negative pole connects vehicle bonding negative pole, begins each cell operation of powering behind the vehicle launch.
Described ultrasonic ranging unit begins the vehicle of entry range is carried out the probe vehicles distance behind vehicle launch, and vehicle distance data is reached the data microprocessing unit.
Described data microprocessing unit is that real-time vehicle distance data is carried out analysis and judgement, in real time vehicle distance data changes and is divided into increase, maintains an equal level and dwindles three kinds of situations, and spacing is and increases and when fair, the data microprocessing unit is judged as two car spacing safety, and control LED digital display screen is made normal spacing and shown; When spacing dwindles, the data microprocessing unit is judged as front truck has deceleration or braking or back car that acceleration is arranged, control LED digital display screen displaying contents makes high frequency flicker and sound Tip element is made sounding, reaches aid prompting front and back vehicle driver with this and notices that spacing changes safe driving.
Range cells, data microprocessing unit, sound Tip element, digital display screen are prior art.
