Abstract

The utility model relates to a driving safety distance warning device. The back part of a vehicle body is provided with a wave source transmitter and a signal receiving unit, and signals are reflected backwards by the latter. The safety distance of the speed of the vehicle can be detected by the speed and distance detection unit. When the closing object is over the safety distance, a warning lamp and a buzzer which are arranged in the vehicle can be started to remind the driver of the vehicle to know the possible danger on back side and warning. On the other hand, a third brake lamp on the back side can also be started to cause the attention of the back vehicle in order to make both sides warn and strain in real time to ensure the better driving safety.

Description

The safety driving distance warning device

The utility model relates to a kind of traffic safety warning device, refers to a kind of safety driving distance warning device of judging the speed of a motor vehicle and safe distance between vehicles especially.

Because people come and go land transportation still based on automobile, therefore with regard to traffic accident, also be maximum with the automobile, though some traffic accidents are because the intentional contrary to traffic regulation of chaufeur causes, but be minority after all, still have many situations to be in fact because human negligence, or pay no attention to for the moment, very fast and after a period of time because of the speed of a motor vehicle again because the illusion that visual fatigue produced, and make chaufeur think by mistake the speed of a motor vehicle be not actual fast, when by the time critical condition being arranged, stepping on brake again has been that distance is not enough, causes the horrors of giving birth to more, has caused many misfortune and domestic tragedy.

Main purpose of the present utility model just is to provide a kind of safety driving distance warning device, by this device the detection of spacing is started alarming device, reminding this car and the timely strain of back car chaufeur, thereby ensures the safety of driving, and generation cuts down traffic accidents.

Another purpose of the present utility model is: be provided with light and sound caution unit in car, make this car chaufeur can obtain optimal prompting, thereby guarantee traffic safety.

For achieving the above object, the utility model provides a kind of safety driving distance warning device, at least comprise a power supply, a Brake lights, it is provided with wave source projector, received signal unit and speed and distance detecting unit at the car body rear, and behind car, be provided with the 3rd Brake lights, in car, be provided with switch control unit and caution unit simultaneously; Described wave source projector, received signal unit, speed are all in parallel with power supply with distance detecting unit, Brake lights, the 3rd Brake lights, switch control unit and caution unit; Between Brake lights, the 3rd Brake lights, switch control unit and caution unit and power supply, also be respectively equipped with a regulating switch.

Described caution unit includes a Warning light or buzzer phone at least.

Safety driving distance warning device provided by the utility model, it is the warning device of a kind of intelligent judgement speed of a motor vehicle and safe distance between vehicles, it is to be provided with wave source projector and received signal unit at the car body rear, the latter is with the signal of reflected back, judge that through speed and distance detecting unit the speed of this car should have safety distance how long, but sensing starts caution unit set in the car near the distance of thing, can remind this car chaufeur institute vigilance in good time, also start the 3rd Brake lights at rear on the other hand, can cause the attention of back car, so that both sides' vigilance and optimum strain interaction is arranged all to some extent makes traffic safety more obtain to ensure.In addition, the utility model is provided with light and sound caution unit in car, for example: Warning light or buzzer phone, make this car chaufeur can obtain optimal prompting and strain in addition in time, to avoid contingent unnecessary trouble, thereby reach the assurance traffic safety, the effect that cuts down traffic accidents and take place.

Below in conjunction with drawings and the specific embodiments the utility model is further described in more detail.

Fig. 1 is a composition scheme drawing of the present utility model.

Fig. 2 is an enforcement illustration of the present utility model.

Fig. 3 is a circuit diagram of the present utility model.

Please referring to shown in Figure 1, the utility model mainly is on power supply 10 circuits, be parallel with switch control unit 20 wave source projectors 40, received signal unit 41, speed and distance detecting unit 42, Brake lights 50, the 3rd Brake lights 51 and caution unit 60 respectively, above-mentioned member unit can be equipped with the

switch

30,31,32 and 33 of regulation and control in its place ahead, can do in good time unlatching according to need or closes; Wherein wave source projector 40 can be ultrasonic, laser or electromagnetic wave etc., and the ripple that it sent is accepted by received signal unit 41 through reflected back, and is transferred to speed and distance detecting unit 42 forms path in succession.

Warn in addition unit 60 can the lamp source or sound as caution, for example itself be a

buzzer phone

61 and 62 parallel connections of flash caution lamp.

Please referring to shown in Figure 3, Fig. 3 is that wave source projector 40 of the present utility model, received signal unit 41 and speed and distance detecting unit 42 are arranged in the circuit diagram in the car; Please cooperate referring to shown in Fig. 1,2,3, this wave source projector 40 and received signal unit 41 are to be located at the outer rear of car appropriate location again, and the buzzer phone 61 and the flash caution lamp 62 of caution unit 60 can place in the car, and especially the latter can place operator's saddle the place ahead appropriate location; Then after the wave source that wave source projector 40 is sent is got near thing 70, the signal of its reflected back through received signal unit 41 and speed and distance detecting unit 42 judge that the speed of these cars travels down, near between thing 70 and this car safety distance how long being arranged, if surpass this safety distance near thing 70, then start set switch control unit 20 in the car, can be with flash of light Warning light 62, the switch 33 of buzzer phone 61 or other music systems is opened, then make sound and this car of sparkling prompting chaufeur understand that danger may be easily given birth at the rear and vigilance to some extent, also start the switch 32 of the 3rd Brake lights 51 at rear on the other hand, can cause the attention of rear near thing 70, so that both sides vigilance and updated strain all to some extent, to guarantee preferable traffic safety.
