Abstract
The utility model relates to a back vision safety vehicle speed display system which comprises a display screen installed on the rear window of a vehicle. The display screen installed on the rear window of the vehicle is connected with a decoder, a vehicle sensor and a vehicle-mounted power supply in series. The display screen is a light-emitting diode (LED) display screen and is a transparent display screen. The back vision safety vehicle speed display system has the advantages that the speed of the vehicle is displayed by the display screen installed on the rear window of the vehicle in real time for vehicles or pedestrians behind, and therefore when an emergency brake of the vehicle is pulled, drivers of the vehicles behind can timely judge speed reduction of the vehicle before and pull brakes, rear-end collision of the vehicles behind with the vehicle is avoided, running safety is improved and meanwhile running back vision obstacles of the drivers are avoided.
Description
Technical field
The utility model relates to a kind of backsight accident-free vehicle speed indication system, belongs to the on-vehicle safety apparatus technology.
Background technology
Existing vehicle speed shows all unified middle controlling disk positions that is installed in vehicle, and purpose is to be convenient to the real-time speed of a motor vehicle that chaufeur is in time understood institute's steering vehicle.Along with the continuous increase of number of vehicles, normal in the driving process the anxious phenomenon of stopping appears, and the vehicle driver at its rear tends to lead to that vehicle hangs or traffic accident such as vehicle rear-end collision because the visual determination spacing is slipped up.Because the vehicle driver at its rear does not know the instantaneous velocity of front vehicles, only whether light with the stoplight stop lamp of front vehicles or spacing obviously reduces to determine whether brake, thereby increased the danger coefficient of urban drive greatly, also helped supervisory management zone and the public to the supervision of overspeed of vehicle simultaneously.Existing vehicle-carrying display screen all is the read-out of transparent materials, and during driver drives vehicle, often by road conditions behind the central back mirror real time inspection car, but the sight line that the read-out that adopts often blocks chaufeur has increased driving hidden danger greatly.The utility model also adopts transparent display screen to be installed in the vehicle rear window, eliminates driver's driving backsight obstacle, and the vehicle driver who loads this patent can view the shown real-time speed of a motor vehicle that goes out on the transparent display screen by central back mirror.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of backsight accident-free vehicle speed indication system.
The technical solution of the utility model is as follows:
A kind of backsight accident-free vehicle speed indication system comprises the read-out that is installed in the vehicle rear window, and the described read-out that is installed in the vehicle rear window is connected with demoder, car speed sensor and vehicle power, and described read-out is transparent display screen.
Preferred according to the utility model, described read-out is LED display.
Advantage of the present utility model is:
1. a kind of backsight accident-free vehicle speed indication system described in the utility model, the speed of a motor vehicle that shows himself by the read-out that is installed in the vehicle rear window in real time to its rear vehicles or pedestrians, make it when emergency brake, the chaufeur of its front vehicle can in time be judged the reduction of speed of front vehicles, in time make brake, avoid and its generation rear-end collision, improved traffic safety, also help supervisory management zone and the public to the supervision of overspeed of vehicle simultaneously.
2. the utility model also adopts transparent display screen to be installed in the vehicle rear window, eliminates driver's driving backsight obstacle, and the vehicle driver who loads this patent can view the shown real-time speed of a motor vehicle that goes out on the transparent display screen by central back mirror.
3. the utility model circuit structure is simple and easy, is convenient to promote install and use.
Description of drawings
Fig. 1 is circuit connection diagram of the present utility model.
In Fig. 1,1, read-out; 2, demoder; 3, car speed sensor; 4, vehicle power.
The specific embodiment
Below in conjunction with embodiment and Figure of description the utility model is described in detail, but is not limited thereto.
A kind of backsight accident-free vehicle speed indication system comprises the read-out 1 that is installed in the vehicle rear window, and the described read-out 1 that is installed in the vehicle rear window is connected with demoder 2, car speed sensor 3 and vehicle power 4.Described read-out 1 is LED display.
As embodiment 1 described a kind of backsight accident-free vehicle speed indication system, its difference is that described read-out is transparent display screen.
Claims (2)
1. a backsight accident-free vehicle speed indication system is characterized in that this system comprises the read-out that is installed in the vehicle rear window, and the described read-out that is installed in the vehicle rear window is connected with demoder, car speed sensor and vehicle power, and described read-out is transparent display screen.
2. a kind of backsight accident-free vehicle speed indication system according to claim 1 is characterized in that described read-out is LED display.
