Abstract
The utility model relates to an experiment teaching aid, in particular to an experiment teaching aid for simulating an automobile reversing radar, which comprises a power supply, a switch, a photoelectric switch, a relay and a warning circuit, wherein the warning circuit is controlled by the relay, and the power supply, the switch, the photoelectric switch and the relay are connected in series for forming a loop. The utility model has the advantages of simple structure, low cost, good demonstration effect and the like.
Description
Technical field
The utility model relates to a kind of experiment teaching aid, relates in particular to a kind of experiment teaching aid of simulated automotive radar for backing car.
Background technology
Reversing radar of vehicle is the active safety system on the automobile, and it can remind the driver in when reversing, and automobile tail reaches or in time reports to the police exceed safe distance the time.In field research, need a cover can help the automobile major student to understand the experiment teaching aid of reversing radar of vehicle principle of work better.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, and is with low cost, the experiment teaching aid of the simulated automotive radar for backing car of good demonstration effect.
The utility model comprises power supply, switch, optoelectronic switch, relay and warning circuit; Described warning circuit is controlled by relay; Above-mentioned power supply, switch, optoelectronic switch, relay are composed in series a loop.
Work as switch closure, as long as when the distance of barrier and optoelectronic switch is reduced to a certain value (this value can be adjusted), optoelectronic switch conducting, engage relay.Connect warning circuit after the relay adhesive, warning circuit begins to report to the police.Experiment teaching aid in the utility model is simple in structure, with low cost, can be truly, the course of work of simulated automotive radar for backing car visually, and help the student to understand the principle of work of reversing radar of vehicle better, have good demonstration effect.
As improvement of the present utility model, described warning circuit comprises loudspeaker, bulb and flasher; Described bulb is connected electrically on the flasher; Above-mentioned loudspeaker are in parallel with flasher and bulb.
Above-mentioned warning circuit is reported to the police by acousto-optic two aspects, and promptly loudspeaker are when piping, and bulb is intermittently glittering, has demonstrated the course of work of reversing radar of vehicle more visually.
Described power supply is accumulator preferably.
