Description
Technical field
The utility model relates to automotive accessory technical field, specifically a kind of automobile tail safety alarm device.
Background technology
According to the applicant understood; when automobile travels; human pilot often can because the reasons such as the speed of a motor vehicle, rearview mirror angle and human visual scope to produce after car dead angle large before than car; the complete front sided mirror unit of car of leaning on also cannot effectively be observed and know people and thing; especially oversize vehicle, the radius of gyration is large, and dead range is wide; mainly still rely at present driver and estimate judgement, thereby the accident causing occurs often. Spacing before and after in addition when road driving is also difficult to hold, and is easy to have an accident, and causes any property loss and personal injury.
Utility model content
The purpose of this utility model is: the problem existing for above-mentioned prior art, proposes a kind of for the automobile tail safety alarm device that can judge fast, warns and be quick on the draw of barrier closely.
In order to reach above object, automobile tail safety alarm device of the present utility model, comprises the alarming device being arranged on license plate frame, and described alarming device comprises the sensing unit and the alarm unit that are controlled by control module; Described sensing unit comprises the distance measuring sensor being made up of ultrasonic transmit circuit and ultrasonic wave receiving circuit; It is characterized in that: described alarm unit comprises acoustic alarm unit and/or the light alarm unit in the both sides mounting shell that is arranged on described license plate frame, and the horizontal cross-section of described mounting shell is curved;
Transducing signal control end, transducing signal input and the controlling alarm output of described control module connect respectively ultrasonic transmit circuit, ultrasonic wave receiving circuit, and acoustic alarm unit and/or light alarm unit.
The technical scheme that the utility model further limits is:
Further, described acoustic alarm unit comprises the first resistance, triode and the buzzer of series connection successively.
Further, described smooth alarm unit comprises light emitting diode and second resistance of series connection successively.
Further, the below of described license plate frame is also provided with display screen.
Further, also comprise and the power module of master controller connection.
Beneficial effect: the utility model is that acoustic-optic alarm is installed at existing vehicles identifications place, not only simple in structure, generous, have in the back people or vehicle near time sound and light warning, to point out driver or personnel to note keeping at a distance, avoid the generation of accident, ensured the safety of driving. Be provided with display screen at afterbody simultaneously and not only can be used as caveat display screen prompting front vehicle personnel, can also serve as in addition advertising screen, the beneficial effect of generation is to kill two birds with one stone.
