Abstract
The utility model provides an automobile rear-end collision preventing device, which is arranged at the rear part of an automobile and alarms through sound and light signals. The automobile rear-end collision preventing device is fixed on the rear side face of the automobile and is characterized by comprising a power supply used for providing power for electrical components of the whole device, a distance detection unit used for detecting the distance between a following automobile and the automobile, an electric bell and a light bulb used for warning and a control unit used for controlling, and the distance detection unit, the control unit, the light bulb and the electric bell are connected in series and are then connected with the two ends of the power supply. The utility model not only adopts optical signals to warn the following driver not to be too close, but also adopts the sound-type warning tone, thereby achieving better effect.
Description
Technical field
The utility model relates to a kind of automobile anti-rear end collision device, in particular, relates in particular to a kind of automobile anti-rear end collision device that automobile tail utilizes sound and light signal to warn that is arranged at.
Background technology
More and more universal along with family saloon, automobile has become the indispensable vehicle in Modern Family's life, what the increasing of vehicle brought thereupon is increasing of traffic accident, the traffic accident major part all since rear-end collision cause.Though present automobile has the taillight that serves as warning, for this quotidian alarm signal, people more and more are not present to the mind.
Summary of the invention
The utility model has overcome the shortcoming of above-mentioned technical matters, provides a kind of automobile tail that is arranged to receive the automobile anti-rear end collision device that sound and light signal is reported to the police.
For achieving the above object, the utility model has adopted following technical scheme:
Automobile anti-rear end collision device of the present utility model, this automobile anti-rear end collision device is fixed on the trailing flank of automobile, its special feature is: described automobile anti-rear end collision device comprises and is used for the power supply of electric energy, the distance detecting unit that is used to detect rear portion automobile and this automobile distance, electric bell that serves as warning and bulb being provided and starting to control the control unit of making usefulness, the two ends of receiving power supply after described distance detecting unit, control unit, bulb and electric bell are connected in series with electric device to whole device; When detected automobile and when distance between the automobile of this device is installed less than 5 meters, impedance in the described distance detecting unit incircuit is zero, impedance under other situations in the distance detecting unit incircuit is infinitely great, and the circuit that described control unit is used to control after the warning disconnects.
Automobile anti-rear end collision device of the present utility model, described bulb be shaped as lightning shape, triangle or knife-edge.The structure that adopts this shape is in order to play better warning function.
The beneficial effects of the utility model are: Kai Detai is not near not only to adopt optical signal to remind the driver of back to drive, but also adopts the prompt tone of form of sound, makes effect more.
Description of drawings
Fig. 1 is the design sketch after the installation of the present utility model;
Fig. 2 is a circuit theory scheme drawing of the present utility model.
1 power supply, 2 distance detecting unit, 3 control units, 4 bulbs, 5 electric bells.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
As depicted in figs. 1 and 2, this shown device is arranged on the trailing flank of automobile, bulb wherein adopts the general-duty redness, this bulb uses several LED small bulbs to constitute different shapes, be lightning shape for example, this shape can play the warning function of becoming reconciled, shown distance detecting circuit is used to detect the distance of back automobile apart from this automobile, the signal of its output is equivalent to switching value, when within the distance range that the automobile that detects the back is being set apart from the distance of this automobile, it is equivalent to the switch of a closure in circuit, when detected automobile when the distance of this automobile is outside setting value, it is equivalent to an open circuited switch in circuit.Shown control unit 3 is used to control the disconnection of sending the back circuit of reporting to the police, control unit comprises the signal receiver that is arranged in the warning circuit, with the corresponding signal projector of this signal receiver for movably, be placed on the inside of automobile, after signal alarm is reported to the police a period of time, the driver makes warning circuit disconnect by the signal projector that remote control is positioned over automotive interior, stops to report to the police.
Described alarm sound also can adopt the signal of propagandaing directed to communicate, and causes that like this degree that the back automobilist notes is better.
