Abstract

The utility model relates to a device which comprises a casing and an alarm circuit composed of an oscillator, a relay and two sets of displayers, wherein, the output of the oscillator is connected with the relay whose normally open contact and normally closed contact are respectively connected with the power supply end of one set of displayer; the displayer are arranged on the front panel of the casing. An oscillatory wave output by the oscillator causes the relay to obtain electricity and lose electricity alternatively; the normally open contact and the normally closed contact of the relay cause the two sets of displayers to be switched on with the power supply, and thus the two sets of displayers alternatively display set patterns. The utility model uses the form of light to stimulate drivers, and thus the attention of the drivers is not easy to be distracted, and thus the utility model is helpful to driving safety, and can reduce the occurrence of traffic accidents.

Description

The automotive safety annunciator

The utility model relates to a kind of annunciator.

Increasing along with self-propelled vehicle, safety traffic has become important social issue.Because automobile driver has alarming device to remind when driving, chaufeur causes traffic accident because of absent-minded easily.

The purpose of this utility model provides a kind of chaufeur of can reminding constantly and notes the safety warning device of safety traffic.

For reaching this purpose, the utility model adopts following scheme: the automotive safety annunciator, and it comprises shell, it is characterized in that: the warning circuit of being made up of oscillator, relay, two group display equipments is housed in the shell, and wherein: electrical equipment is succeeded in the output of oscillator; The normal opened contact of relay and normally closed contact connect the power end of a group display equipment respectively, the power end of the fixed contact connection circuit of relay; Telltale is contained on the front panel of shell.

Described telltale is made of luminotron and the warning picture hollowed-out board that is contained in before the luminotron, also can be made of the luminotron that is combined into warning picture.

Also can comprise to oscillator and telltale in the described warning circuit galvanic regulator rectifier circuit is provided.

The wave of oscillation of energising back oscillator output makes relay replace electricly and dead electricity, and the normal opened contact of relay and normally closed contact take turns energized with two group display equipments, and such two group display equipments are the pattern set of Alternation Display just.

Because the form that the utility model can be used up stimulates chaufeur constantly, make the thought of chaufeur be difficult for paralysis, so help traffic safety, can reduce traffic accident and take place.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 and Fig. 2 are respectively schematic circuit diagram of the present utility model and profile scheme drawing.

See also accompanying drawing, circuit of the present utility model provides galvanic regulator rectifier circuit to form by oscillator IC2, relay J, red green two group display equipments and for oscillator and telltale.Among the figure: diode D7～D10 constitutes rectifier bridge, and capacitor C 1, C2 and 7806 integrated regulator IC1 form mu balanced circuit; Oscillator adopts 555 time-base integrated circuits, resistance R 1, R2 and capacitor C 3, C4 are the outward element of oscillator IC2, be used to set oscillation frequency, the series connection point of R1 and R2 connects 7 pin of oscillator IC2, the series connection point of R2 and C3 connects 6 pin and 2 pin of oscillator IC2, and the coil of electrical equipment J is succeeded in the output of oscillator IC2; Telltale is made of red luminotron D1～D3, green luminotron D4～D6, current-limiting resistance R3～R8, warning picture hollowed-out board 2, and warning picture hollowed-out board 2 is positioned at before the red and green luminous pipe, and is contained on the front panel of shell 1; The normal opened contact of relay J and normally closed contact connect the power end of red group of luminotron and green group of luminotron respectively, and the fixed contact of relay J connects direct supply.

The utility model is placed in the operator's compartment front portion, after the input end of its rectifier is connected to the source of AC of automobile, the wave of oscillation of oscillator IC2 output makes relay J replace electricly and dead electricity, the normal opened contact of relay J and normally closed contact take turns red green two group display equipments and power connection, two group display equipments are the pattern of Alternation Display setting just, i.e. " taking care " printed words of Alternation Display redness and green " guarding the friendship method rigidly " printed words.

If directly adopt the direct supply of automobile, then the regulator rectifier circuit in the circuit can be save.

In other embodiment of the present utility model, telltale also can be made of luminotron, promptly without hollowed-out board, only is combined into warning picture with luminotron.
